For health reasons, the number of people making and drinking green juice or juice at home is increasing, and for this purpose, many devices that allow users to easily make juice from vegetables or fruits at home are being released.

In the past, juicers put ingredients into an inlet, crushed them with blades rotating at high speed, and made juice using a centrifugal method. However, these juicers may destroy the inherent taste and nutrients of the ingredients during the high-speed crushing process, and it is difficult to make green juice from vegetables with stems or leaves, and it is also difficult to make juice from fruits with high viscosity such as kiwi or strawberry. In fact, it was completely impossible to make soy milk from soybeans.

To solve this problem, Republic of Korea Patent No. 10-0793852 uses a method of compressing and pulverizing ingredients between a mandrel and a screw rotating at low speed, using the principle of grinding soybeans with a millstone and pressing them to produce soymilk. It has the effect of making juice by grinding and pressing fruits with high viscosity such as tomatoes, kiwi, and strawberries on a grater, so it was possible to solve the problems of the conventional juicer as described above.

However, even in this case, there was the inconvenience of having to cut the material into small pieces in advance before putting it into the inlet due to the size of the screw and the size of the inlet that was manufactured to allow the appropriate size of material to be injected according to the size of the screw.

That is, the rotational force of the drive shaft 130 is transmitted to rotate the screw 230 inside the juice drum 280 and the cut portion 225 inside the hopper 210 to cut and compress the input juice material to generate juice. Separate the juice and residue and discharge them.

As shown in FIG. 2, the juicer 200 can be installed in the main body 100 as shown in FIG. 1 only when the hopper 210 is fastened to the upper part of the juice drum 280. That is, in the present invention, the hopper 210 cannot be attached to the upper part of the juice drum 280 when only the juice drum 280 is seated on the main body 100. If the juicer is operated with only the juice drum 280 seated on the main body 100, the user may suffer unexpected injuries. As will be described later, in the present invention, power is supplied to the juicer only when the lid of the hopper 210 is closed while the juicer 200 is seated on the main body 100, so that the user may be harmed by unintentional operation of the juicer. Try to prevent injury in advance. In addition, mechanically, the entire juice unit 200 can be seated on the main body 100 only when the juice unit 200 is assembled, thereby further ensuring user safety. A description of the structure related to this will be provided later.

Hereinafter, each component constituting the juice extraction unit 200 and the configuration of the main body 100 will be described in more detail with reference to the drawings.

The hopper 210 is detachably coupled to the upper part of the juice drum 280. The hopper 210 forms a space for storing the input juice ingredients (eg, fruits, vegetables, grains, etc.). The cutting part 225, which is rotatably fixed on the bottom surface of the hopper 210, receives power from the screw 230 and rotates to cut and stir the juice material and supply it to the juice drum 280 below. Therefore, in the present invention, since the cutting of the juice material is carried out within the hopper 210, there is no need to pre-cut the juice material before inserting it.

The hopper 210 can be largely divided into a hopper housing 215 and a lid portion 220, and a cut portion 225 can be mounted inside the hopper 210, so it may be referred to as a hopper 210 including the cut portion 225. It may be possible.

The hopper housing 215 has a cylindrical or truncated cone shape and forms a space through which juice is supplied through the open upper part.

As shown in FIG. 8, the bottom surface of the hopper housing 215 may be formed to be separable from the upper cylindrical body, but it is not necessarily limited to this and may be formed integrally.

A cutting part 225 can be rotatably mounted on the upper part of the bottom of the hopper housing 215. The cutting part 225 receives power from the screw 230 inside the juice drum 280 and is connected to the screw 230. They can rotate together.

On the inner surface of the hopper housing 215, comb protrusions 2151 may be formed along the circumferential direction, protruding long inward in the longitudinal direction. This is to prevent light juice ingredients such as leafy vegetables from absorbing moisture and sticking to the inner surface of the hopper housing 215 and to enable them to be easily removed. At this time, it is preferable that comb protrusions 2151 are formed on the entire inner surface of the hopper housing 215.

A handle portion 216 may be formed on one side of the outer peripheral surface of the hopper housing 215 to allow the user to hold the container. As shown, the handle portion 216 may extend in a ring shape from the upper end of one side of the cylindrical hopper housing 215 and extend to the lower end of the hopper housing 215. The lower end of the handle portion 216 must be the hopper housing. (215) It does not need to be configured to be connected to the lower end.

As shown, the handle portion 216 may be formed in a shape that includes a vertical surface extending vertically downward after the horizontal surface extends a predetermined distance from the upper part of the hopper housing 215, and the horizontal surface of the upper part includes a lid portion ( A fastening hole 2161 may be formed into which the hook fastening part 2221 of 220) is inserted and fastened.

A penetrating connection hole 2152 is formed in the center of the bottom of the hopper housing 215. Through the connection hole 2152, the upper rotating shaft 233 of the screw 230 located below the hopper 210 and the cut portion 225 located on the upper bottom of the hopper 210 can be connected to enable power transmission. The detailed structure regarding this will be described later.

At least one penetrating discharge hole 217 may be formed between the center of the bottom surface and the edge of the hopper housing 215. The juice material in the hopper 210 is cut and stirred by the cutting part 225 rotatably fixed on the bottom surface of the hopper 210, passes through the discharge hole 217, and is placed in the juice drum disposed below the hopper 210. It can be supplied as (280). In the drawing, one discharge hole 217 is formed on one side of the bottom surface of the hopper 210. The larger the number of discharge holes 217 or the size of the area of the discharge hole 217, the greater the amount (or the larger the size). The juice materials can be supplied to the juice drum (280). However, if too much of the juice material is supplied into the juice drum 280, a load may be placed on the screw 230, so the size and size of the discharge hole 217 are adjusted so that the juice material of the appropriate amount and size can be supplied. It is desirable to set the number.

As shown in FIGS. 12 and 13, the width of the discharge hole 217 may be formed to gradually widen along the rotation direction of the cut portion 225. Therefore, the soft juice material or the small crushed juice material is allowed to immediately flow into the screw 230 through the narrow portion at the front of the discharge hole 217 in the direction of rotation, and the hard juice material or the relatively large crushed juice is allowed to flow into the screw 230. The material can be allowed to remain inside the hopper 210 and be further pulverized by the cutting portion 225 and discharged through the wide portion at the rear end of the discharge hole 217 in the direction of rotation.

Additionally, an inclined surface 2171 inclined toward the discharge hole 217 may be formed on the inner surface of the bottom of the hopper housing 215. At this time, it is preferable that the inclined surface 2171 is formed to slope downward along the rotation direction of the cutting portion 225. Since the height of the part where the inclined surface 2171 and the discharge hole 217 come into contact is lower than the height of the inner bottom surface of the hopper housing 215, the juice material can be efficiently guided toward the discharge hole 217. The inclined surface 2171 allows juice material that may be stuck or stagnant between the inner bottom surface of the hopper housing 215 and the cutting blade 227 of the cutting unit 225 to be smoothly moved downward.

Furthermore, as shown in FIG. 13, in the present invention, an inclined surface 2172 may be formed on the outer bottom surface of the hopper housing 215 (bottom surface of the hopper 210). The inclined surface 2172 is formed to slope downward from the discharge hole 217 along the rotation direction of the cut portion 225 to enable the juice material to be smoothly supplied to the juice drum 280 through the discharge hole 217. . The inclined surface 2171 formed on the inner surface of the bottom of the hopper housing 215 and the inclined surface 2172 formed on the outer surface of the bottom of the hopper housing 215 are the front end of the discharge hole 217 along the rotation direction of the cut portion 225, respectively. They are formed at the upper and rear ends, respectively, and the inclined directions are all inclined downward along the rotational direction of the cutting portion 225.

Figure 14 shows a modified example of the bottom surface of the hopper 210. In this embodiment, like the above-described embodiment, the width of the discharge hole 217 is formed to gradually widen along the rotation direction of the cutting portion 225. . At this time, an inclined surface 2173 is formed that slopes radially downward from the center of the hopper 210 toward the discharge hole 217. Since the width of the discharge hole 217 gradually widens along the rotational direction of the cutting part 225, the radial width of the inclined surface 2173 gradually narrows along the rotational direction of the cutting part 225. The size of the discharge hole 217 may be formed to gradually decrease in the vertical direction due to the inclined surface 2173. In this way, the inclined surface 2173 formed in the radial direction toward the discharge hole 217 effectively guides the juice material downward and allows the juice material to stay a little longer within the discharge hole 217, thereby adding juice material. An effect that can be cut occurs.

On the outer edge of the lower part of the hopper housing 215, a predetermined number of binding protrusions 2174 are formed that protrude long in the horizontal direction, and these are formed along the circumference of the binding protrusion 2801 formed on the inner edge of the upper part of the juice drum 280. ) so that the juice drum 280 and the hopper 210 are detachably coupled.

The lid portion 220 is formed to be able to open and close the open upper part of the hopper housing 215. An additional inlet 2201, which is a penetrating hole, may be formed in the center of the lid portion 220. When a relatively small size of juice material needs to be added during the juice extraction operation, the juice material can be supplied into the hopper 210 through the additional inlet 2201. In addition, the push bar 290 can be inserted through the additional inlet 2201 to apply force so that the juice material inside the hopper 210 moves to the lower part of the hopper 210. Although not shown, a separate stopper may be formed to block the additional inlet 2201.

As shown in FIG. 9, the additional input port 2201 is located in the center of the lid portion 220. At this time, when the push rod 290 is inserted through the additional inlet 2201, the lower end of the push rod 290 is added so that it is located above the center of the cut portion 225 disposed on the inner lower surface of the hopper 210. The inlet 2201 is formed so as not to cause interference with the cutting portion 225. In particular, the cutting portion 225 of the present invention may be formed of a cutting blade 226 extending upward in the form of a spiral and a cutting blade 227 extending horizontally on the bottom surface of the hopper, as will be described later. Since the cutting blade 226 is formed to extend upward in the form of a spiral, no interference occurs even when the lower end of the pressing rod 290 is inserted inside the cutting blade 226, so the pressing rod is raised to just above the rotation center of the cutting portion 225. (290) can be manufactured sufficiently long.

A hinge coupling portion in which a pinhole 2203 penetrating in the horizontal direction is formed is formed on one side of the edge of the lid portion 220, more specifically, on the side opposite to where the handle portion 216 of the hopper housing 215 is formed. By placing the pinhole 2203 of the hinge joint between the pin fixing holes 2153 formed on both sides of the top of the hopper housing 215 and inserting the pin 224 into the pin fixing hole 2153 and the pin hole 2203. The lid portion 220 may be hinged to the upper part of the hopper housing 215. That is, in the present invention, the lid portion 220 is hinged to the hopper housing 215 and is formed separately or integrally with the hopper housing 215.

The magnet placement portion 221 extends vertically downward from the hinge coupling portion. A first magnet 2211 is disposed inside the magnet placement portion 221 to detect the open/closed state of the lid. As will be described later, a second magnet 1102 may be disposed inside the upper body 110. When the lid 220 is opened and closed, the magnet placement portion 221 rotates and changes its position, thereby changing the first magnet 1102. The magnetic force changes as the distance between the magnet 2211 and the second magnet 1102 changes, and whether the lid portion 220 is opened or closed can be detected by the movement of the second magnet 1102 according to the change in magnetic force. A detailed description of this will be provided later with reference to FIGS. 49 to 50.

When the lid portion 220 is opened, the magnet arrangement portion 221 extending vertically downward from the hinge coupling portion rotates toward the inside of the hopper housing 215, so interference with the outer surface of the hopper housing 215 may occur. there is. Therefore, as shown, on the outer surface of the hopper housing 215 where the magnet arrangement part 221 is located, the hopper housing 215 forms a space in which the magnet arrangement part 221 can move toward the center of the hopper 210. ) An interference prevention groove 2154 recessed inward may be formed.

The lid handle portion 222 protrudes outward from the lid portion 220 covering the open upper surface of the cylindrical hopper housing 215 on one side opposite to the hinge coupling portion and is located at the upper part of the handle portion 216. The lid handle portion 222 may be fastened to the handle portion 216 at the top of the handle portion 216. The lid handle portion 222 is formed to protrude from the lid portion 220 covering the open upper surface of the hopper housing 215 in a horizontal plane having a predetermined width, and a hook fastening portion 2221 is provided on the bottom of the lid handle portion 222. is formed protruding downward. At this time, the hook fastening portion 2221 is formed to protrude vertically downward to have a plate surface in the width direction of the lid handle portion 222 so that it can be pressed toward the user by the user's finger.

As described above, the upper horizontal surface of the handle portion 216 has a fastening hole 2161 that extends long in the width direction and has a shape corresponding to the cross section of the hook fastening portion 2221 so that the hook fastening portion 2221 can be inserted through it. This is formed.

In addition, a fixing step 2222 is formed on the outer surface of the hook fastening part 2221 so that the hook fastening part 2221 is caught on the side of the lower edge of the fastening hole 2161 and the lid part 220 is fixed without opening. There is a number.

Therefore, when the hook fastening part 2221 of the lid part 220 is inserted into the fastening hole 2161 and the fixed step 2222 of the hook fastening part 2221 is caught on the lower edge side of the fastening hole 2161, the lid While the part 220 covers the upper open surface of the hopper housing 215, artificial opening is prevented.

Conversely, while the user is holding the handle portion 216, he or she presses the hook fastening portion 2221 toward the user with a finger such as the index finger to release the fixed step 2222 caught on the edge of the fastening hole 2161, and in this state, the thumb The lid portion 220 can be opened by applying force to lift the lid handle portion 222 upward with the fingers of the back.

Furthermore, anti-rotation ribs 2224 may be formed on both edges of the bottom of the lid handle 222, protruding long downward in the direction in which the lid handle 222 protrudes. The anti-rotation rib 2224 is supported from both upper edges of the handle 216 when the lid 220 is closed, so that the lid 220 fastened to the upper part of the hopper housing 215 through the hinge joint is horizontal. Avoid turning in one direction.

As shown in FIG. 7, a safety guide portion 223 may be formed to protrude vertically downward along the bottom edge of the lid portion 220 and be inserted into the upper inner portion of the hopper housing 215. The safety guide portion 223 prevents the user's hand from entering the inside of the hopper housing 215 when the lid portion 220 is opened at a certain angle. As described above, the juicer of the present invention does not operate when the lid portion 220 is opened by the operation of the first magnet 2211 and the second magnet 1102, and the safety guide portion 223 is connected to the lid portion 220. ) Even if the lid part 220 is partially opened due to a sensing error of the open/closed sensing unit 115 that detects the open/closed state, it is not detected, thereby preventing unexpected safety accidents from occurring. In addition, the safety guide portion 223, together with the anti-rotation rib 2224, may also serve to prevent the lid portion 220 from rotating in the horizontal direction.

The safety guide portion 223 may be formed to protrude inside the hopper 200 at a certain height along the edge of the bottom surface of the lid portion 220, but gradually protrudes from the side away from the hinge joint toward the hinge joint as shown. The bottom surface can be formed to be inclined so that the protrusion height is reduced.

Figure 11 shows a modified example of the safety guide portion 223. As shown, the bottom of the lid portion 220 protrudes toward the inside of the hopper housing 215, and the bottom surface of the lid portion 220 protrudes toward the inside of the hopper housing 215. It may be formed to be inserted into the housing 215. The bottom of the lid portion 220 may also be formed as an inclined surface so that the protruding height gradually decreases from the side away from the hinge coupling portion toward the hinge coupling portion.

In this way, the safety guide portion 223 is formed in such a way that a portion of the lid portion 220 is inserted into the upper inner portion of the hopper housing 215, so that when the lid portion 220 is opened at a certain angle, the user's hand moves into the hopper housing. (215) It can be prevented from entering the interior.

The cut portion 225 is rotatably coupled to the inner bottom surface of the hopper 210 and rotates inside the hopper 210 by receiving rotational force from the screw 230 located inside the juice drum 280. The juice material introduced inside is cut and stirred, and the cut juice material is supplied into the juice drum 280 located below the hopper 210 through the discharge hole 217 formed on the bottom surface of the hopper 210.

In the present invention, the cutting unit 225 rotates inside the hopper 210 with both sides supported between the bottom and top of the hopper 210, and does not cut the juice material, but is supported on one side at the bottom of the hopper 210. Since the juice material is cut in this state, an open space free from interference is formed on the upper side of the cut portion 225 in the hopper 210. Accordingly, since the entire upper side of the cutting unit 225 forms an open space, large-sized juice materials such as whole fruits can be inserted into the hopper 210 and cut.

Next, the cut part 225 is rotatably coupled to the bottom surface of the hopper housing 215 and a structure that rotates the cut part 225 by receiving rotational force from the screw 230 is shown in FIGS. 8, 9, 20, and The description will be made with reference to FIG. 26.

A bushing portion 218 is disposed in the connection hole 2152 formed on the bottom of the hopper housing 215. The radial inner and outer surfaces of the bushing portion 218 are formed in a cone shape whose radius decreases toward the top, and are protruded in the form of a circular flange at the bottom to form a step 2181. A cone-shaped inclined surface and a locking protrusion 2158 are formed on the inner surface of the connection hole 2152 to correspond to the shape of the outer surface of the bushing portion 218. At this time, the bushing portion 218 may be formed integrally with the bottom surface of the hopper housing 215 by insert injection.

The connection hole 2152 and the bushing portion 218 are in contact with each other in the form of a cone whose radius decreases toward the top, so that even if an upward force is applied when the screw 230 rises due to a load during the juicing process, the hopper bottom surface and the bushing Since the coupling force between the parts 218 can be firmly maintained, deformation due to the screw 230 rising can be prevented.

A hole is formed in an open top and bottom shape inside the bushing portion 218, and the power transmission portion 219 is inserted. When the screw 230 rotates with the upper rotating shaft 233 of the screw 230 inserted into the power transmission unit 219, the power transmission unit 219 inserted inside the bushing unit 218 is inserted into the bushing unit 218. ) Since it rotates internally, the bushing portion 218 is preferably formed of a material that is not easily deformed by friction that occurs when the power transmission portion 219 rotates.

The power transmission part 219 may be composed of a coupling part 2191 and an upper protrusion 2195. To correspond to the shape of the inner surface of the bushing portion 218, which is formed in a cone shape whose radius decreases toward the top, the outer surface of the coupling portion 2191 is also formed in a cone shape whose radius decreases toward the top. The interior of the coupling portion 2191 is formed with a shaft hole 2192 into which the upper rotation shaft 233 of the screw 230 is inserted. The upper rotation axis 233 of the screw 230 may be formed as a square shaft, and the shaft hole 2192 may be formed as a square shaft hole. In this embodiment, the upper rotation axis 233 of the screw 230 is formed as a hexagonal axis, and the axis hole 2192 may be formed as a 12-angle axis hole 2192, which is a multiple of 2. The shaft hole 2192 formed in the power transmission unit 219 may also be formed as a hexagonal shaft hole to correspond to the shape of the upper rotation shaft 233 of the screw 230, but the shaft hole 2192 may be formed as a 12-angle multiple of 2. When formed, the coupling between the upper rotating shaft 233 of the screw 230 and the power transmission unit 219 can be made easier. Furthermore, coupling can be made easier by forming an inclined surface that expands the size of the axial hole at the entrance of the 12-angled axial hole 2192. Therefore, in order to facilitate the coupling between the two members, when the upper rotation axis 233 of the screw 230 is formed as an n-shaped square axis, the shaft hole formed in the coupling part 2191 of the power transmission unit 219 is It can be formed with a 2*n square axial hole.

At this time, when the power transmission unit 219 is fastened to the bushing unit 218, the bottom surface of the power transmission unit 219 is located above the bottom surface of the hopper 210, and the bottom surface of the shaft hole 2192 is a step ( 2181) is located above the bottom surface. Therefore, the bottom surface of the shaft hole 2192 is located inside the bottom surface of the hopper 210 and does not protrude the bottom surface of the hopper 210 (see partially enlarged view of FIG. 9). Therefore, interference does not occur due to unnecessary protrusion and material costs are reduced.

An upper protrusion 2195 is formed on the upper part of the coupling portion 2191. When the power transmission portion 219 is inserted into the bushing portion 218 from the bottom of the hopper housing 215, the upper protrusion 2195 is a bushing portion ( It passes through the hole of 218 and protrudes onto the upper surface of the bushing portion 218 and is located inside the hopper 210. At this time, the upper protrusion 2195 is formed in a quadrangular shape, and a rectangular groove 2251 is formed on the bottom of the cut part 225 in a corresponding shape, so that the cut part 225 can be coupled to the upper protrusion 2195. there is. The shape of the upper protrusion 2195 and the corresponding shape of the groove 2251 on the bottom of the cut portion 225 are not limited to this and may be modified in various ways, such as a cross shape or a spline shape.

In a state where the upper protrusion 2195 and the groove 2251 on the bottom of the cut portion 225 (see FIGS. 20 and 26) are coupled, the screw 2199 is inserted through the shaft hole 2192 of the coupling portion 2191 to The cut portion 225 is attached to the upper protrusion 2195 by screwing it into the screw hole 2196 penetrating the protrusion 2195 and the screw groove 2252 formed at the rotation center of the bottom of the cut portion 225 (see FIGS. 20 and 26). ) can be firmly fixed.

A step is formed at the top of the shaft hole 2192 formed on the inner surface of the coupling portion 2191 to limit the insertion depth of the upper rotation axis 233 of the screw 230, and the head of the screw 2199 is located at the top based on the step. is located.

As described above, when the inner surface of the bushing part 218 and the outer surface of the power transmission part 219 contact each other in a cone shape whose radius decreases toward the top, the screw 230 receives a rising force. Avoid injury to the screw 230. Furthermore, as the power transmission unit 219 receives force directed upward, the power transmission unit 219 and the bushing unit 218 become more concentric, so mechanical stability can be improved.

15 and 16 show a sealing structure formed in the hopper 210. As described above, the hopper 210 is attached to the upper part of the juice drum 280, and the sealing structure serves to seal between the two members 210 and 280. As shown, the packing ring 211 may be fixed along the outer edge of the hopper 210. At this time, in the present invention, the packing ring 211 may be formed in a vertically symmetrical structure. Since the packing ring 211 is formed in a vertically symmetrical structure, the packing ring 211 can be assembled in both directions, and the problem of poor packing performance due to the vertical direction being changed during assembly can be solved. For reference, Figure 15 shows the lower part of the hopper 210.

The packing ring 211, which is formed in the shape of a circular ring, is inserted into the fixing groove, which is a groove formed along the outer edge of the lower part of the hopper 210, and the radial direction from the upper and lower ends of the fixing part 2111, respectively. It may be formed to include a packing wing portion 2112 that protrudes in the shape of a wing.

As described above, the hopper 210 and the juice drum are connected by the engaging protrusion 2174 formed on the outer edge of the lower end of the hopper housing 215 and the engaging protrusion 2801 formed on the inner edge of the upper part of the juice drum 280. (280) can be settled. The two members 210 and 2880 can be coupled by inserting the coupling protrusion 2174 through the space between the coupling protrusions 2801 and rotating it to position the coupling protrusion 2174 under the coupling protrusion 2801. .

At this time, if an inclined surface is formed on the binding surface of the coupling protrusion 2174 as shown, the relative position between the coupling protrusion 2801 and the coupling protrusion 2174 is changed when the hopper 210 and the juice drum 280 are coupled. Depending on this, the vertical position of the hopper 210 with respect to the juice drum 280 may be changed. As the coupling between the juice drum 280 and the hopper 210 progresses by the coupling protrusion 2174 and the binding protrusion 2801, the binding protrusion 2801 is formed by an inclined surface formed on the binding surface of the binding protrusion 2801. The vertical contact position of the coupling protrusion 2174 is changed. At this time, as the combination progresses, the hopper 210 moves toward the juice drum 280 in the direction of the inclined surface, and the upper surface of the juice drum 280 contacts the lower side of the packing wing portion 2112. The packing wing portion 2112 is pressurized. At this time, in the drawing, an inclined surface is formed on the binding surface of the coupling protrusion 2174, but as the coupling between the hopper 210 and the juice drum 280 progresses, the upper surface of the juice drum 280 becomes the packing wing portion 2112. ) can be pressed, an inclined surface may be formed on the binding surface of the binding protrusion 2801, or an inclined surface may be formed on both the binding surfaces of the binding protrusion 2801 and the binding protrusion 2174.

Figures 16 (a) and (b) show the shape of the packing ring 211 before and after the juice drum 280 and the hopper 210 are combined, respectively, in which the binding protrusion 2801 rises to form the packing wing portion ( 2112) is raised by pressurizing the lower side and sealing is performed. Therefore, the sealing force can be improved by increasing the pressing force through the inclined surface formed on the binding surface.

At this time, as shown in (b) of FIG. 16, when the combination of the juice drum 280 and the hopper 210 is completed, the packing wings 2112 located at the top and bottom are prevented from contacting each other, thereby reducing friction. It is desirable to improve the fastening properties of the hopper.

The cutting unit 225 is rotatably coupled to the bottom surface of the hopper 210 and rotates by receiving rotational force from the screw 230 through the power transmission unit 219 to cut and stir the juice material.

The cutting portion 225 may include a cutting blade 226 and a cutting blade 227. The cutting blade 226 and the cutting blade 227 can rotate at the same speed. At this time, the cutting blade 226 and the cutting blade 227 may be formed as one piece, and therefore the cutting blade 226 and the cutting blade 227 rotate together at the same speed.

The cutting blade 226 extends upward from the rotation center in the direction of rotation of the cutting portion 225 in the form of a spiral. The upper end of the cutting blade 226 is preferably formed in a sharp hook shape with a cross-section that becomes smaller toward the end. In addition, the cutting blade 226 is not formed in a plate shape but is formed to have a predetermined thickness. The cross-section becomes smaller as it goes upward, and it is curved in a spiral and extends upward, so that it is formed in the shape of a bull's horn.

The cutting blade 226, which is in the form of a hook and faces upward, is mainly responsible for cutting and crushing the juice material introduced to the upper part. In addition, as the cutting blade 226 is formed not in a plate shape but in a shape with a predetermined flesh thickness, it is possible to prevent stem vegetables such as water parsley from being caught on the cutting blade 226. In addition, the spirally extending shape of the cow horn serves to guide the cut juice material to move downward. At this time, the radially inner surface of the cutting blade 226 is formed with an inclined curved surface 2261 so that it faces radially outward toward the bottom, so that the cutting blade 226 rotates and the juice crushed by the cutting blade 226 is extracted. Allows the material to move smoothly downward along the curved surface.

The higher the height of the top of the cutting blade 226, the higher the crushing effect. It is preferable that the cutting blade 226 be formed at least higher than the height of the upper surface of the cutting blade 227. In addition, the radial length of the cutting blade 226 is preferably formed as long as possible in the radial direction within a range that does not interfere with the inner surface of the hopper 210.

The cutting blade 227 is formed to extend horizontally on the lower surface of the hopper 210. The cutting blade 227 is preferably formed to have a predetermined thickness in the vertical direction. As shown, a blade is formed at the top where the inclined surfaces of the front and rear sides of the rotation direction of the cutting blade 227 meet. At this time, as shown in FIG. 18, the end of the cutting blade 227 may be formed so that its height gradually decreases in the radial direction. The cutting blade 227 serves to secondarily crush the juice material that has been crushed and moved downward from the cutting blade 226 by the blade formed at the top, and at the same time, the cutting blade 227 has a predetermined thickness. As it is formed, the juice material located on the bottom surface of the hopper 210 is pushed so that it can be smoothly discharged through the discharge hole 217. This is because if the thickness of the cutting blade 227 is thin, it may not be able to push the juice material located on the bottom surface of the hopper 210 and may spin around.

It is preferable that the cutting blade 227 extends from the rotation center of the cutting portion 225 at a position 180 degrees opposite to the direction in which the cutting blade 226 extends, but it is not necessarily limited to this. At this time, the cutting blade 227 is preferably formed in a shape that is curved in a direction opposite to the rotation direction of the cutting portion 225.

Therefore, in the present invention, the cutting blade 226 and the cutting blade 227 exist in opposite directions from the rotation center, but the blade ends of the cutting blade 226 and the cutting blade 227 are bent toward each other, so that the cutting part The overall shape of (225) is similar to a crescent moon.

In addition, since the cutting blade 226 and the cutting blade 227 are not located on the same plane and the cutting blade 226 has a shape that is bent in a spiral and extends upward, the overall shape of the cutting portion 225 is like a crescent moon. It is similar to this, but has a distorted shape in space.

Like the cutting blade 226, the cutting blade 227 is preferably formed as long as possible in the radial direction within a range that does not interfere with the inner surface of the hopper 210.

As described above, a rectangular groove 2251 may be formed at the rotation center of the bottom of the cut portion 225 to correspond to the shape of the upper protrusion 2195 of the power transmission unit 219, which is formed in a square shape, and a rectangular groove ( A screw groove 2252 into which a screw is fastened is formed above 2251). By fastening the cut part 225 using a screw 2199 with the square groove 2251 inserted into the upper protrusion 2195 of the power transmission unit 219, the cut part 225 is formed on the inner bottom surface of the hopper housing 215. (225) can be rotatably mounted.

Figure 21 shows a modified example of the cut portion 225. In this embodiment, a circular protrusion 2250 protruding in a circular ring shape is formed on the bottom of the cut portion 225. As shown in FIG. 22, a circular groove 2150, which is a circular groove into which the circular protrusion 2250 is inserted, is formed on the lower surface of the hopper 210 to correspond to the circular protrusion 2250. Therefore, as shown in FIG. 23, the cutting part 225 rotates with the circular protrusion 2250 inserted into the circular groove 2150, so the waste in the hopper 210 flows toward the rotation axis of the cutting part 225. You can prevent it from happening. Furthermore, it is possible to solve the problem of long vegetables or fibers, such as stem vegetables, being wound around the rotation axis of the cutting unit 225.

In this embodiment, an uneven structure in which a circular protrusion 2250 is formed on the bottom of the cut portion 225 and a circular groove 2150 is formed on the bottom surface of the hopper 210 is explained as an example. However, on the contrary, the cut portion 225 It may be formed as a concavo-convex structure in which a circular groove is formed on the bottom of the hopper 210 and a circular protrusion is formed on the bottom of the hopper 210.

At this time, a waste discharge portion 21501 is formed in the circular groove 2150 on the lower surface of the hopper 210, which communicates with the circular groove 2150 and discharges the waste caught in the circular groove 2150 to the outside of the circular groove 2150. It can be. As shown in FIG. 22, the waste discharge unit 21501 includes a groove further drilled downward at a predetermined position of the circular groove 2150, and one side of the outer surface of the circular groove 2150, including the outer surface of the groove. It may be formed in the form of an open open surface. Accordingly, as the cutting part 225 rotates, the debris caught in the circular groove 2150 can be pushed into the groove and discharged through the open surface on the outside, or can be discharged directly through the open surface on the outside of the circular groove. At this time, it is desirable to allow the waste to be discharged through the open surface toward the discharge hole 217 formed on the bottom of the hopper 210.

At this time, the cut portion 225 according to an embodiment of the present invention may be formed as a double structure including a core body 2255 and a shell 2259 covering the outside of the core body 2255 made of a different material from the core body 2255. there is. As shown in FIGS. 24 and 25, the core body 2255, which is made of a material with relatively stronger strength than the outer shell 2259, forms the inside of the cut portion 225 and covers the outer surface of the core body 2255. The outer shell 2259 is formed to have a predetermined thickness.

The cutting portion 225 must be made of an eco-friendly, high-strength, easy-to-process, and lightweight material that is harmless to the human body. In particular, in the case of the cutting blade 226, when it rotates, a strong load is applied due to contact with the uncut juice material that is first put into the hopper 210, and if strength is not secured due to the geometrical characteristics of the hook, it can be easily broken. There is a number. Accordingly, in the present invention, the inside of the cut portion 225 forms a core body 2255 made of a strong material, and the cut portion 225 has a double structure of a shell 2259 that covers the outside of the core body 2255 and is made of a different material from the core body 2255. ) was formed to ensure rigidity and at the same time satisfy the remaining conditions required for the cut portion 225.

At this time, the core body 2255 may be formed of an Ultem material, and the outer shell 2259 may be formed of a POM (polyoxymethylene or polyacetal) material or an ABS (Acrylonitrile butadiene styrene) material.

The core body 2255 and the outer shell 2259, which are made of two different materials, can be manufactured to be strongly joined by insert injection. The overall shape of the core body 2255 may have a shape similar to the overall shape of the cutting portion 225 and corresponding to the shape of the cutting blade 226 and the cutting blade 226. The core body 2255 has a surface of the core body 2255. A protrusion 2256 protruding from the core body 2255, a groove 2257 recessed from the surface of the core body 2255, or a through hole 2258 penetrating the core body 2255 are formed to increase the bonding force between the core body 2255 and the outer shell 2259. to increase. At this time, the outer surface of the protrusion 2256, the inner surface of the groove 2257, and the inner surface of the through hole 2258 are formed as curved surfaces to increase the bonding area between the core body 2255 and the outer shell 2259. , Furthermore, the bonding force between the core body 2255 and the outer shell 2259 can be strengthened by contacting in multiple directions through the valley curved surface. Furthermore, the coupling area can be further increased by forming the outer surface of the protrusion 2256, the inner surface of the groove 2257, and the inner surface of the through hole 2258 into curved surfaces.

In this embodiment, as shown, a protrusion 2256 and a groove 2257 are formed to continuously extend at the rotation center portion of the cut portion 225, and protrusions 2256 of a predetermined shape are formed to be spaced apart along the rotation direction. , A through hole (2258) is formed in the area corresponding to the cutting blade (226) where a strong load is applied to strengthen the bonding force.

In addition, as shown in FIG. 26, a coupling member having a square groove 2251 and a screw groove 2252 formed on the bottom of the cut portion 225 that couples the power transmission portion 219 and the cut portion 225. It is preferable to prepare (2254) separately and manufacture the coupling member (2254), core body (2255), and shell (2259) by insert injection.

The cutting portion 225 according to the present invention is rotatably fixed to the bottom surface of the hopper 210, and may be detachable. The cut portion 225 may be contaminated by juice extract material, but in the present invention, the cut portion 225 is made detachable so that the cut portion 225 can be separated from the hopper 210 and easily cleaned. Hereinafter, the detachment structure of the cut portion 225 will be described with reference to FIGS. 27 to 36.

First, Figures 27 to 30 show the detachment and attachment structure of the cut portion 225 according to an embodiment of the present invention.

In this embodiment, as described above, the bushing portion 218 is disposed in the connection hole 2152, and the power transmission portion 219 is inserted into the bushing portion 218. The configuration of the power transmission unit 219 including the coupling portion 2191, the upper protrusion 2195, and the shaft hole 2192 into which the upper rotation shaft 233 of the screw 230 is inserted is described above with reference to FIGS. 8 and 9. The configuration is the same, and in this embodiment, a locking portion 2197 is formed protruding in the radial direction from the outer surface of the pillar protruding above the upper protrusion 2195. At this time, two locking portions 2197 may be formed to protrude on both sides symmetrically by 180 degrees.

The power transmission part 219 is inserted into the connection hole 2152 from below the lower end of the hopper 210, and then the cut part 225 is formed with a square through hole 2253 on the central axis according to the shape of the upper protrusion 2195. ) is inserted into the upper protrusion 2195 and fixed, the locking portion 2197 protrudes toward the upper part of the cut portion 225. At this time, the cut part 225 can be rotatably fixed to the lower surface of the hopper 210 by the fixing cap 228 that inserts and fixes the locking part 2197 at the top of the cut part 225.

The fixing cap 228 is a member that covers and fixes the locking portion 2197 protruding above the cut portion 225, and is opened from the bottom of the fixing cap 228 to the top so that the locking portion 2197 can move up and down. An upper and lower guide portion 2281 that provides and an insertion portion 2282 that allows the locking portion 2197 to be inserted and fixed in the circumferential direction are formed at the top of the upper and lower guide portions 2281. At this time, as described above, when two locking portions 2197 are formed to protrude symmetrically, two upper and lower guide portions 2281 and two insertion portions 2282 may also be formed symmetrically.

Therefore, when the fixing cap 228 is moved downward with the lower end of the upper and lower guide portions 2281 positioned at the position of the locking portion 2197, the locking portion 2197 is positioned at the top of the upper and lower guide portions 2281. At this time, when the fixing cap 228 is rotated in the circumferential direction, the locking portion 2197 is located in the insertion portion 2282. Therefore, the fixing cap 228 can be fixed to the power transfer unit 219 with the cut part 225 positioned between the power transfer unit 219 and the fixing cap 228. When separating the cut portion 225 from the hopper 210, the above process can be reversed by rotating the fixing cap 228 in the opposite direction.

At this time, an elastic body 2284 made of an elastic material may be fixed to the bottom of the fixing cap 228. The elastic body 2284 may be formed of rubber, for example. As shown, the elastic body 2284 is formed in the shape of a circular ring, and the bottom of the fixing cap 228 has a fixing groove 2285 dug in the shape of a circular ring so that the elastic body 2284 can be inserted and fixed. ) can be formed.

The bottom of the elastic body 2284 is preferably formed to protrude downward from the bottom of the fixing cap 228. Therefore, a force is applied to press the fixing cap 228 downward from the upper part of the cut portion 225, and the fixing cap 228 is rotated only in a state in which the elastic body 2284 is compressed, thereby attaching the locking portion 2197 to the insertion portion 2282. By allowing it to be located in , the fixing force by the fixing cap 228 can be further strengthened.

Additionally, a seating groove 2283 may be formed on the bottom surface of the circumferential end of the insertion portion 2282 so that the locking portion 2197 may be seated thereon. When the locking portion 2197 is located at the upper part of the seating groove 2283, the fixing cap 228 moves upward due to the elastic force of the elastic body 2284, so that the locking portion 2197 cannot be seated in the seating groove 2283. there is. Accordingly, the locking portion 2197 is caught in the seating groove 2283 to prevent the fixing cap 228 from being easily disengaged. In order to release the coupling of the fixing cap 228, the fixing cap 228 is pressed downward to release the locking portion 2197 from being caught in the seating groove 2283, thereby compressing the elastic body 2284 to release the locking portion (2197) from the fixing groove 2283. 2197) is positioned spaced apart from the upper part of the seating groove 2283, and in this state, the fixing cap 228 can be rotated in the circumferential direction to release the fixed coupling of the fixing cap 228.

Next, Figures 31 to 33 show the detachment and attachment structure of the cut portion 225 according to another embodiment of the present invention.

In this embodiment, a rotation support portion 229 is formed on the rotation axis of the cutting portion 225 to rotatably support the cutting portion 225. Accordingly, an axis bundle is formed that allows the cutting portion 225 to rotate relative to the rotation support portion 229. The rotation support part 229 functions as the bushing part 218 described above and has a shape that protrudes out of the connection hole 2152 when inserted into the hopper 210 for detachment.

When the shaft assembly including the rotation support portion 229 is inserted into the connection hole 2152 formed at the center of the bottom surface of the hopper 210 from the inside of the hopper 210, the rotation support portion 229 is connected to the hopper 210. It protrudes below the bottom surface. At this time, the cutting part 225 including the shaft assembly can be fixed to the bottom surface of the hopper 210 by fixing the fixing part 2295 to the outer circumference of the rotation support part 229 protruding below the bottom surface of the hopper 210. there is. Conversely, when the coupling between the fixing part 2295 and the rotation support part 229 is released, the cutting part 225 including the shaft bundle can be separated from the hopper 210.

The fixing part 2295 may be formed in a circular ring shape, and has at least one fixing protrusion 2296 protruding inward in the radial direction. In this embodiment, three fixing protrusions 2296 are formed radially inward at equal intervals.

To correspond to the fixing part 2295, a path is provided on the outer peripheral surface of the rotation support part 229 that is open from the bottom of the rotation support part 229 to the top so that the fixing protrusion 2296 of the fixing part 2295 can move up and down. An upper and lower guide portion 2292 in which a groove is formed and an insertion portion 2293 that is a groove into which the fixing protrusion 2296 is inserted in the circumferential direction may be formed at the top of the upper and lower guide portion 2292. Therefore, in a state in which the rotation support part 229 protrudes below the lower end of the hopper 210, the fixing protrusion 2296 of the fixing part 2295 is positioned below the lower end of the upper and lower guide parts 2292, and then the fixing part 2295 ) is raised so that the fixing protrusion 2296 is located at the top of the upper and lower guide parts 2292, and in this state, the fixing part 2295 is rotated so that the fixing protrusion 2296 of the fixing part 2295 is inserted into the insertion part 2293. ), so that the fixing part 2295 can be fixed to the outer peripheral surface of the rotation support part 229. With the fixing part 2295 fixed to the outer peripheral surface of the rotation support part 229, the upper surface of the fixing part 2295 is in contact with the bottom surface of the hopper 210 to firmly fix the cutting part 225 including the shaft assembly. There is a number.

A gripping part 2297 is formed that protrudes outward in the radial direction of the fixing part 2295, so that a force is applied by holding the gripping part 2297, so that the fixing part 2295 can be easily rotated when engaging or disengaging. .

In addition, at least one guide protrusion 2291 is formed at a predetermined position on the outer peripheral surface of the rotation support part 229, and a guide protrusion 2291 is formed on the inner surface of the connection hole 2152 to correspond to the guide protrusion 2291. A guide groove portion 21521 into which is inserted may be formed. When inserting the cut portion 225 including the shaft assembly through the connection hole 2152, the insertion position of the shaft assembly can be guided by inserting the guide protrusion 2291 into the guide groove portion 21521.

Next, Figures 34 to 36 show the detachment and attachment structure of the cut portion 225 according to another embodiment of the present invention.

In this embodiment, a rotation support portion 229 is formed on the rotation axis of the cutting portion 225 to rotatably support the cutting portion 225, and the configuration of forming the shaft bundle is the same as the above-described embodiment. However, in this embodiment, rather than being fixedly coupled by the fixing part 2295 below the bottom surface of the hopper 210, the shaft assembly including the rotation support part 229 is connected to the center of the bottom surface of the hopper 210. The difference is that it is directly detachably coupled to the hole 2152.

In this embodiment, at least one fixed protrusion 2294 is formed on the outer surface of the rotation support unit 229, and an insertion portion (not shown) into which the fixed protrusion 2296 is inserted is formed on the inner peripheral surface of the connection hole 2152. You can. Although not shown, the rotation support portion 229 is similar to the configuration in which the fixing protrusion 2296 of the fixing portion 2295 is inserted and fixed into the insertion portion 2293 formed on the outer periphery of the rotation support portion 229 in the above-described embodiment. The fixed protrusion 2294 protruding from the outer circumferential surface of the connection hole 2152 is inserted into the insertion part (not shown) formed on the inner circumferential surface of the connecting hole 2152. It can be fixed to .

In addition, as shown, fixed steps 21522 are formed on the inner peripheral surface of the connection hole 2152 and are spaced apart in the circumferential direction and protrude radially inward, and a fixed protrusion (21522) is formed between the space between the fixed steps 21522. 2296) is inserted, the shaft assembly including the rotation support portion 229 is rotated so that the fixing protrusion 2296 is located below the fixing step portion 21522, and the cutting portion 225 including the shaft assembly is formed. It can be fixed to the bottom of the hopper 210.

Again, explaining the configuration of the hopper 210, at least one first inner protrusion 2155 that interacts with the cutting blade 226 may be formed on the inner surface of the hopper 210. As shown in FIG. 9 , the first inner protrusion 2155 may be formed to protrude long and downward on the inner surface of the hopper 210 in a vertical direction. The first inner protrusion (2155) interacts with the cutting blade (226), and the juice material inserted into the hopper 210 is caught on the first inner protrusion (2155) and plays a role in holding it, so that the juice material inserted into the hopper (210) is caught by the cutting blade (226). Improve crushing efficiency. If the first inner protrusion 2155 is not present, the juice material rotates with the cutting blade 226 and may not be cut. However, the juice material can be easily crushed by rotating the cutting blade 226 while the juice material is supported in the rotation direction by the first inner protrusion 2155. Therefore, it is preferable that the first inner protrusion 2155 protrudes inward at a relatively large height compared to the second inner protrusion 2157, which will be described later, so as to support the juice material in the radial direction.

One side of the outer peripheral surface of the hopper 210 is indented inside by the above-mentioned interference prevention groove 2154, and as shown, the first inner protrusion 2155 can be formed together with the interference prevention groove 2154.

At this time, the lower end of the first inner protrusion 2155 may be formed to be located at the upper end of the cutting blade 226. As shown in (a) of FIG. 9, the lower end of the first inner protrusion 2155 has two sides. A penetration groove 2156 penetrating may be formed. At this time, the upper end of the cutting blade 226 can pass through the through groove 2156. By forming a through groove 2156 at the lower end of the first inner protrusion 2155 to correspond to the shape of the upper end of the cutting blade 226, the lower end of the first inner protrusion 2155 and the upper end of the cutting blade 226 are mutually They can be positioned to overlap. At the same time, the radial length of the cutting blade 226 can be made larger, thereby improving cutting efficiency.

Figure 10 (a) shows a modified example of the positional relationship between the first inner protrusion 2155 and the cutting blade 226. In this embodiment, the lower end of the first inner protrusion 2155 and the cutting blade 226 They do not overlap but are spaced apart from each other. That is, the upper end of the cutting blade 226 is located below the lower end of the first inner protrusion 2155.

However, in this embodiment as well, a through groove 2156 (see FIG. 9 (b)) that penetrates both sides of the lower end of the first inner protrusion 2155 and is recessed toward the top may be formed. At this time, the through groove 2156 provides a space where the material crushed by the first inner protrusion 2155 and the cutting blade 226 can be smoothly discharged in the circumferential direction. When hard vegetables or fruits, such as carrots, are caught in the first inner protrusion (2155), a lot of load is applied, and the first inner protrusion (2155) and the cutting blade (226) are separated by the space secured by the through groove (2156). ) to ensure that the shredded material can be discharged smoothly.

Figure 10(b) shows another modified example of the positional relationship between the first inner protrusion 2155 and the cutting blade 226. In this embodiment, the end line of the inner end of the first inner protrusion 2155 Based on the extending virtual line, the upper outer end line of the cutting blade 226 is the same or is located further inward in the radial direction. In this way, larger-diameter materials can be more smoothly crushed using the cutting blade 226 and fed into the juice drum.

Additionally, at least one second inner protrusion 2157 that interacts with the cutting blade 227 may be formed on the inner surface of the hopper 210. As shown in FIG. 9, the second inner protrusion 2157 may be formed on the inner surface of the hopper 210 to protrude inward in the radial direction corresponding to the rotating position of the end of the cutting blade 227. The second inner protrusion 2157 interacts with the cutting blade 227, and prevents the juice material from spinning around on the upper part of the cutting blade 227, allowing the juice material to flow smoothly into the discharge hole 217. . Some of the juice material located on the bottom of the hopper 210 is pushed as the cutting blade 227 rotates and flows into the discharge hole 217, and the other portion gradually moves outward in the radial direction due to centrifugal force. If there is no protrusion 2157, the juice material located on the upper part of the cutting blade 227 may not flow into the discharge hole 217 and may spin around on the upper part of the cutting blade 227. At this time, the juice material pushed out of the upper part of the cutting blade 227 by centrifugal force may collide with the second inner protrusion 2157 and fall off from the cutting blade 227.

In this embodiment, the second inner protrusion 2157 is formed below the first inner protrusion 2155. In addition, a discharge hole 217 is formed perpendicularly below the first inner protrusion 2155 and the second inner protrusion 2157, so that the discharge hole 217 is cut and separated through the first inner protrusion 2155 and the second inner protrusion 2157. The juice material falls vertically so that it can be supplied directly into the juice drum 280 through the discharge hole 217.

Hereinafter, the screw 230, juice separation drum 260, and juice drum 280, which constitute the juice unit 200 and are located below the hopper 210, will be described. First, the screw 230 will be described with reference to FIGS. 37 to 40.

Figure 37 is a perspective view of the screw shown in Figure 4, Figure 38 is a side view of Figure 37, Figure 39 is a perspective view showing the bottom of the screw shown in Figure 37, and Figure 40 is a perspective view showing the bottom of the screw shown in Figure 37 to Figure 39. This is a modified example of a screw.

The screw 230 is mounted inside the juice separation drum 260, receives rotational force from the drive shaft 130 of the main body 100, rotates, and compresses and crushes the juice material together with the juice separation drum 260.

The screw 230 may be formed to include a screw body 231 and a screw thread 232 protruding in the form of a spiral on the outer surface of the screw body 231.

As shown, the screw body 231 may be divided into an upper part and a lower part centered around the part with the largest radius of the screw body 231. At this time, the upper part forms a cutting section that further cuts the juice material input from the hopper 210, and the lower part forms a juice section that generates juice by pressing the juice material in earnest below the cutting section.

The lower part of the screw body 231 is formed so that the radius becomes gradually smaller as it goes downward. By making the radius smaller as it goes downward, it is possible to form a space where the residue separated by juice is located. However, the shape of the lower part of the screw body 231 is not limited to this and, for example, may be formed straight downward without changing the radius.

In addition, the upper part of the screw body 231 is formed so that the radius gradually decreases as it goes up, and as shown, the radius change according to the height change is greater than that of the lower part of the screw body 231. The tip of the screw body 231 has the smallest radius and is formed so that the radius gradually increases as it goes downward. According to this shape, large-sized materials can be transported while being gradually reduced in size by compression and crushing. creates space. In other words, since the diameter of the upper part of the screw body 231 gradually increases downward, the size of the space through which the material formed by the screw body 231 together with the screw thread 232 is transported gradually increases along the material transport direction. becomes smaller. That is, the material is compressed and pulverized by the rotation of the screw 230, and its size gradually decreases, and it moves down the screw 230 along the gradually decreasing transport space along the screw thread 232 formed in the downward direction. It will be done.

The screw thread 232 is formed to protrude in the form of a spiral on the outer peripheral surface of the screw body 231, and the juice object is squeezed into the narrow gap between the screw 230 and the juice separation drum 260 by the screw thread 232. and is transported downward. At this time, the screw thread 232 is preferably protruded so as to contact or be close to the juice separation drum 260. As described above, the radius of the upper part of the screw body 231 becomes smaller as it goes upward, so the protruding height of the screw thread 232 increases as it goes towards the upper part of the screw body 231.

The screw thread 232 may be formed as one or a plurality of screw threads. In the present invention, one screw thread (the first screw thread 232-1) of the plurality of screw threads 232 is located at the top of the screw body 231. A single-edged screw 230 that extends to form a single blade 2321 at the top of the screw body 231 can be used. Since a lot of load is applied when using a double-edged screw in which two screw threads extend symmetrically to the top of the screw body 231, the present invention uses a single-edged screw 230, but is not necessarily limited thereto.

At this time, in the present invention, the radius of the outer blade 2321 at the top of the screw body 231 may be formed to protrude outward to be larger than the longest radius of the screw body 231. In this way, while maintaining the size of the screw body 231 as before, the radius of the single blade 2321 is made larger than the longest radius of the screw body 231, thereby securing a wider space for the juice material to be input from the top. I can do it. This allows the juice material divided in the upper hopper 210 to be more smoothly introduced into the screw 230.

As shown, a second screw thread 232-2 may be formed starting from the upper part of the screw body 231, which is the juice section, and spiraling downward, and the first screw at the lower part of the screw body 231. Another plurality of third screw threads 232-3 may be formed between the screw thread 232-1 and the second screw thread 232-2. Therefore, the width between neighboring screw threads 232 formed in the screw body 231 is formed to have a relatively wide gap at the upper part of the screw body 231, and a plurality of screws are formed at the lower part of the screw body 231. It is formed to have a relatively narrow gap by the screw thread 232. That is, the cutting section at the top of the screw 230 mainly performs the function of crushing large-sized juice objects, and the juice section at the bottom of the screw 230 performs the juice function through crushing and compression by rotation of the screw 230. can mainly be performed.

Additionally, a plurality of debris guide jaws 235 protruding outside the radius of the lower end of the screw body 231 may be formed in the circumferential direction. The debris guide jaw 235 performs the function of sweeping downward the debris separated by juice and transported below the juice separation drum 260 when the screw 230 rotates. In this way, the debris caught under the juice separation drum 260 can be smoothly removed by the debris guide jaw 235 formed on the outer peripheral radius of the lower end of the screw 230, thereby further increasing the juice extraction efficiency.

The upper rotating shaft 233 of the screw 230, which protrudes above the top of the screw body 231, is formed as a square shaft and is coupled to the square shaft hole 2192 of the power transmission portion 219 to transmit power to the cutting portion 225. do.

In addition, the lower rotating shaft 234 of the screw 230, which protrudes downward from the hollow interior of the screw body 231, is formed as a square shaft hole and is inserted into the square drive shaft 130 protruding from the upper part of the main body 100. and receives power from the motor 1001. As described in the coupling structure between the upper rotation shaft 233 of the screw 230 and the power transmission unit 219, the drive shaft 130 is formed as an n-angle rectangular shaft, and the lower rotation shaft 234 of the screw 230 is formed as a 2n angle shaft. It can also be formed with a square shaft hole to facilitate coupling between the two members. For example, when the drive shaft 130 is formed as a hexagonal shaft, the lower rotation shaft 234 of the screw 230 may be formed as a 12-square shaft hole.

A gripping portion 236 may be formed on the top of the screw body 231. The gripper 236 may be formed to protrude from the top of the screw body 231 at a predetermined horizontal angle with the single blade 2321, which allows the user to use the screw 230 mounted in the juice drum 280 for reasons such as cleaning. This is so that it can be easily removed by holding it together with the outer blade (2321).

Figure 40 shows a modified example of the screw 230 described above. In this embodiment, a circular ring or belt is formed at the boundary between the cutting section and the juice section and the upper and lower parts of the screw 230. An over-injection prevention rib 239 is formed that protrudes from the screw body 231 along the circumferential direction to a predetermined thickness.

The overfill prevention rib 239 is used to prevent overloading of the juice section by the pressure of the screw 230 when a large amount of the juice material in the cutting section is supplied to the juice section at once. The overfill prevention rib 239 reduces the gap between the screw 230 and the juice separation drum 260, thereby preventing a large amount of juice material from being input into the space between them at once.

Since the configuration of the remaining screw 230 except for the over-injection prevention rib 239 is the same as described above, description of the same configuration will be omitted.

Hereinafter, the juice separation drum 260 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 41 to 43.

Figures 41 and 42 are an exploded perspective view of the juice separation drum shown in Figure 4, and Figure 43 is a partially cut away combined perspective view of the juice separation drum.

As shown, the juice separation drum 260 according to the present invention can be constructed by combining the inner module 240 and the outer module 250. Here, the inner module 240 and the outer module 250 may be made of a material such as polyetherimide (PEI).

The inner module 240 has a generally cylindrical shape and may be open at the top and bottom. Here, the inner module 240 includes a plurality of inner plate portions 241, and a plurality of slits 242 are formed long in the vertical longitudinal direction by the plurality of inner plate portions 241.

Here, the plate portion 241 is named for convenience in explaining the design. When dividing the cylindrical module into a hole portion in which the slit 242 is formed and a plate portion in which the slit 242 is not formed, the plate portion in which the slit 242 is not formed is The plate part is defined as “plate part (241)”.

At this time, the width of the slit 242 on the upper side of the slit 242 may be smaller than the width of the slit 242 on the lower side. That is, the width of the slit 242 may become narrower toward the top.

Additionally, a plurality of first rib jaws 244 that protrude long along the vertical and longitudinal directions may be formed on the inner peripheral surface of the inner module 240 along the circumferential direction. The first rib jaw 244 compresses or crushes the material through interaction with the screw thread 232 as the screw 230 rotates. If the first rib jaw 244 is not present, the juice object may not go down and stagnate, or the compression force or grinding force may be low or not generated. At this time, the first rib jaw 244 may be formed on one side of the slit 242 of the inner module.

Additionally, a predetermined number of second rib jaws 243 that protrude long along the vertical and longitudinal directions may be formed on the inner surface of the inner module 240 along the circumferential direction. The second rib jaw 243 transports the juice material inputted into the juice separation drum 260 to the lower part and performs the function of pulverizing the object to be juiced. The second rib jaw 243 may perform the function of reinforcing the rigidity of the inner module 240 and may serve the function of guiding the juice object into the juice separation drum 260. In addition, the second rib jaw 243 may perform the function of adjusting the position of the screw 230 and the juice space.

The protruding height of the second rib jaw 243 may be formed to have the same height from the top to the bottom of the inner module 240, but is preferably formed to gradually decrease from the top to the bottom of the inner module 240. It can be. In addition, the second rib jaw 243 is formed to slope downward from the top to the bottom of the inner module 240, and a stepped portion 2431 is formed in the middle portion protruding toward the screw 230. You can. The position, number, or protruding height of the step portion 2431 may be modified in various ways depending on the shape of the screw 230 and the design conditions of the screw thread 232. The number and arrangement of the second rib jaws 243 may be varied as needed considering design conditions and juice extraction efficiency. In the embodiment of the present invention, the formation direction of the second rib jaw 243 has been described as an example of being formed perpendicular to the vertical direction of the inner module 240, but the scope of the present invention is not limited thereto.

At this time, the first rib jaw 244 is formed on the lower inner surface of the inner plate portion 241 (more specifically, one side of the slit 242), and the second rib jaw 243 is formed on the inner surface of the inner plate portion 241. It is formed entirely from top to bottom.

As shown, the upper end of the inner module 240 is formed with an expansion portion 245 whose radius increases toward the top. Since the upper end of the inner module 240 is expanded in a trumpet shape, the outer blade 2321 at the top of the screw 230 inside the expanded part 245 can rotate without interference.

In addition, a material inflow guide portion 246, which is a curved portion that gradually faces inward along the rotation direction of the screw 230, may be formed on one side of the expansion portion 245. If there is no material inflow guide part 246, a problem may occur where the juice material does not flow downward and spins around with the single blade 2321 on the expansion part 245, when the juice material rotates with the single blade 2321. By contact with the material inflow guide portion 246, it can be induced to break away from the single blade 2321 and move downward. Furthermore, by forming a smooth curved surface, the problem of material being caught in the material inlet guide portion 246 can be solved. The upper surface of the material inflow guide portion 246 is formed so as not to interfere with the bottom surface of the single blade 2321.

At this time, the material inflow guide portion 246 may be formed integrally with the second rib jaw 243 at the upper end of the second rib jaw 243, or may be formed separately from the second rib jaw 243. Additionally, the material inflow guide portion 246 may be formed in plural pieces spaced apart in the circumferential direction. As shown in FIG. 12, at least one of the material inlet guide parts 246 is preferably located below the discharge hole 217 of the hopper 210. The material inflow guide portion 246 located below the discharge hole 217 allows hard juice materials or relatively large crushed juice materials to stagnate inside the hopper 210 so that they can be sufficiently cut by the cutting portion 225.

A predetermined number of fitting protrusions 247 are formed on the bottom surface of the inner module 240. When the inner module 240 and the outer module 250 are coupled, the fitting protrusions 247 are formed on the outer module 250. ) is inserted into the fitting groove portion 258 formed on the bottom of the frame, thereby coupling the two members 240 and 250.

Next, the outer module 250 will be described. The outer module 250 has a generally cylindrical shape and includes an outer plate 251 with open upper and lower sides and a rib 252 protruding from the inner surface of the outer plate 251.

The outer plate portion 251 accommodates the inner module 240 inside, and the outer module 250 and the inner module 240 can be detachably coupled. That is, when the outer module 250 is combined with the inner module 240, it can be combined to accommodate and surround the inner module 240 inside. At this time, the outer module 250 may surround and support the inner module 240.

When the outer module 250 and the inner module 240 move up and down and are coupled, the ribs 252 are inserted into and coupled to the slit 242 below the slit 242 of the inner module 240. At this time, a fine gap is formed between the slit 242 and the rib 252, and the juice generated inside the juice separation drum 260 can be discharged to the outside through the gap.

As such, in this embodiment, the slit 242 of the inner module 240 and the rib 252 of the outer module 250 are combined to discharge juice through the gap between the slit 242 and the rib 252. Since it forms a ball, it is very easy to clean the inner module 240 and the outer module 250 by separating them.

At this time, the ribs 252 may be formed to correspond to the shape of the slit 242 described above. The width of the ribs 252 becomes narrower toward the top, so that the width of the ribs 252 on the upper side is greater than that on the lower side. It may be smaller than the width of the rib 252.

When the outer module 250 and the inner module 240 are moved up and down and coupled by the shape of the rib 252 and the slit 242 as described above, the width is relatively lower at the lower part of the relatively wide slit 242. The outer module 250 and the inner module 240 can be easily combined by inserting the upper part of this small rib 252.

Additionally, a plurality of juice discharge holes 253 may be formed at the lower end of the outer plate portion 251.

In this way, the juice formed inside the juice separation drum 260 formed by combining the inner module 240 and the outer module 250 is formed through the slit 242 of the inner module 240 and the rib 252 of the outer module 250. ) It can be discharged to the outside of the juice separation drum 260 through the slit hole, which is a fine gap formed between the juice, and the juice discharge hole 253 formed in the outer module 250.

At this time, it is preferable that the gap formed between the slit 242 and the rib 252 be formed so that the width of the gap gradually increases in the radial direction to facilitate discharge of juice. For example, when the width of the slit 242 gradually increases in the radial direction, the size of the slit gradually increases in the radial direction.

Furthermore, the width of the gap is made smaller as it goes down in the longitudinal direction, so as to prevent the residue generated by being pulverized more finely as it goes down from being discharged through the gap, and strong pressure by the screw 230 is used. It is desirable to support it.

At the top of the outer module 250, a predetermined number of drum fixing parts 259 are formed that protrude in the horizontal direction, which are inserted into the drum fixing groove 2802 formed on the top of the juice drum 280, which will be described later, and the juice drum ( The position of the juice separation drum 260 can be fixed within 280).

In addition, a predetermined number of fitting grooves 258 are formed on the bottom surface of the outer module 250. When the inner module 240 and the outer module 250 are coupled, the fitting protrusion 247 is formed on the outer module 250. It is inserted into the fitting groove 258 formed on the bottom of 250 to couple the inner module 240 and the outer module 250.

In this embodiment, the juice separation drum 260 is used to form an outflow hole by combining the inner module 240 and the outer module 250, but the previously widely known net drum with a plurality of circular mesh holes formed on the drum surface is used. It is okay to use . Additionally, in this embodiment, a rib 252 is formed on the outer module 250 and a slit 242 is formed on the inner module 240 to discharge juice when the inner module 240 and the outer module 250 are combined. An outlet hole is formed, but the juice is discharged by forming the above-described rib 252 on the inner surface of the juice drum 280 and inserting the inner module 240 without forming a separate outer module 250. An outflow hole may be formed.

Hereinafter, the juice drum 280 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 44 to 48.

Figure 44 is a partially cut away perspective view of the juice drum shown in Figure 4, Figure 45 is a perspective view of the juice drum showing the juice stopper opened in Figure 44, and Figure 46 is a rear view of the juice stopper shown in Figure 45. It is a perspective view showing, FIG. 47 is a perspective view showing the bottom of the juice drum shown in FIG. 44, and FIG. 48 is a perspective view of the lower part of the waste discharge port shown in FIG. 47.

The juice drum 280 has an overall shape of a cylindrical container and accommodates a juice separation drum 260 and a screw 230 inside, and a hopper 210 can be fastened to the top as described above.

At the center of the bottom of the juice drum 280, a waterproof cylinder 281 with a through hole 2805 is formed to protrude upward, and the lower rotating shaft 234 of the screw 230 is inserted through the through hole 2805 to form a driving shaft. It can be combined with (130). The waterproof cylinder 281 is formed to protrude upward to prevent juice from flowing into the drive shaft 130 through the through hole 2805. In addition, a packing ring 2811 made of a material such as rubber or silicon is inserted into the edge of the through hole 2805 to more effectively block juice from flowing into the drive shaft 130. In the present invention, as shown in FIG. 3, a double packing that is fixed between the upper and lower sides of the upper end of the waterproof cylinder 281 and packs the upper and lower sides together can be used.

At the outer lower part of the juice drum 280, a juice outlet 285 through which juice is discharged and a residue outlet 284 through which residue is discharged may be disposed at positions spaced apart from each other.

A plurality of binding protrusions 2801 are formed on the inner edge of the upper portion of the juice drum 280. The binding protrusions 2174 formed on the outer edge of the lower part of the hopper housing 215 described above are positioned between the binding protrusions 2801. Then, the juice drum 280 and the hopper 210 can be coupled by placing the engaging protrusion 2174 below the binding protrusion 2801 by slightly pressing and rotating the hopper 210 downward. At this time, the coupling protrusion 2801 has a rotation stopper 2803 at an end in the fastening direction to prevent further rotation of the coupling protrusion 2174 to maintain coupling between the two members 210 and 280.

In addition, when the coupling protrusion 2174 of the hopper 210 is placed in the space between the two neighboring coupling protrusions 2801, the space between the two coupling protrusions 2801 is maintained so that the coupling protrusion 2174 can sufficiently move left and right. It is desirable to secure it widely. As described above, in the present invention, since the lower rotating shaft 234 of the screw 230 is composed of an n-shaped square shaft and the shaft hole of the power transmission unit 219 is composed of a 2n-shaped square shaft hole, the user can use the hopper 210 This is to secure rotation space so that the power transmission unit 219 can be positioned to be held and rotated and inserted into the lower rotation shaft 234 of the screw 230.

In addition, a fixing groove 2804 is formed on the outside of the bottom of the juice drum 280, and is combined with the fixing protrusion 122 formed on the upper surface of the main body 100, from which the drive shaft 130 protrudes, to produce juice on the upper part of the main body 100. Allows the drum 280 to be fixed.

A first circular protrusion 282 is formed on the bottom surface of the juice drum 280 and protrudes in a circular shape at a position spaced a predetermined distance from the inner surface of the juice drum 280. The outer module 250 of the juice separation drum 260 is seated on the inner surface of the first circular protrusion 282. At this time, the juice separated from the juice separation drum 260 is stored on the circular bottom surface between the inner surface of the juice drum 280 and the first circular protrusion 282 and can be discharged through the juice outlet 285. . It is preferable that the circular bottom surface is inclined toward the juice outlet 285 so that the juice flows toward the juice outlet 285 due to its own weight.

In addition, a second circular protrusion 283 protruding in a circular shape is formed around the waterproof cylinder 281 on the bottom surface of the juice drum 280. The inner ring 237 of the screw 230 is seated in the space between the second circular protrusion 283 and the waterproof cylinder 281, and the outer ring 238 is seated on the outer side of the second circular protrusion 283 to secure the screw. Fix the position of (230).

At this time, in the present invention, an insert ring 2381 made of stainless steel is formed on the inner surface of the outer ring 238 to reduce wear caused by friction between the outer ring 238 and the second circular protrusion 283.

A residue discharge hole 2806 may be formed on one side of the outer bottom surface of the second circular protrusion 283 so that the residue separated in the juice separation drum 260 can be discharged. The residue discharge hole 2806 is connected to the residue discharge port 284 so that the residue inside the juice separation drum 260 can be discharged to the outside.

A waste packing 287 made of an elastic material such as rubber or silicon may be formed in the waste discharge hole 2806. One end of the residue packing 287 on the bottom of the juice drum 280 may be fixed and the other end may be fixed so that it can freely rotate. When no external force is applied from the inside of the juice separation drum 260 to the outside, the residue packing 287 closes the residue discharge hole 2806, and when an external force is applied, it is elastically deformed to open the residue discharge hole 2806. do. Accordingly, the residue inside the juice separation drum 260 reaches the bottom surface of the juice drum 280 and is discharged through the residue discharge port 284 by pushing the residue packing 287.

At this time, in the present invention, the waste discharge port 284 may not be formed in a fixed form on one side of the juice drum 280, but may be formed in a structure that opens and closes by rotation.

As shown, the portion forming the upper end of the waste discharge hole 2806 and the waste discharge port 284 where the waste packing 287 is fixed is formed integrally with the main body 100 of the juice drum 280, and the waste discharge port ( The lower part of the waste discharge port 2842, which forms the lower part of the juice drum 284, is rotatably hinged to the bottom of the juice drum 280. A packing ring 2844 is installed on the upper surface of the bottom of the waste discharge port 2842 to surround the waste discharge hole 2806 to prevent juice or waste from leaking to the outside. A 'ㄷ' shaped fixing ring 2843 is rotatably coupled to one end of the bottom of the waste discharge port 2842.

Therefore, the lower part of the waste discharge port 2842 is rotated to form the upper part of the waste discharge port 284 in a state in which it is brought into close contact with the bottom surface of the juice drum 280, and a fixing ring is attached to the portion 2849 that protrudes outward from the juice drum 280. When (2843) is rotated and fixed, a waste discharge port 284 is formed through which waste is discharged through the waste discharge hole 2806.

Conversely, by rotating the fixing ring 2843 to release the coupling and rotating the lower part of the waste discharge port 2842 downward, the waste packing 287 can be exposed to the outside, and the user can use the waste packing 287 and the waste discharge port ( 284) The inner side can be cleaned.

A juice stopper 286 is rotatably coupled to the end of the juice outlet 285. The juice outlet 285 can be opened and closed by rotating the juice stopper 286, which is rotatably hinged to the upper part of the juice outlet 285. Packing 2861 is attached to the inside of the juice stopper 286 to prevent juice from leaking out of the juice outlet 285.

Hereinafter, the main body 100 according to an embodiment of the present invention will be described.

Figure 49 is an exploded perspective view of the main body shown in Figure 2, Figure 50 is a perspective view of the opening/closing sensing unit shown in Figure 3, Figures 51 to 56 respectively show other variations of the structure for preventing release of the hopper, and Figure 57 is an separated perspective view of the floating motor shaft shown in FIG. 49, and FIG. 58 is a partially cut away perspective view of the floating motor shaft explaining the operation of the floating motor shaft.

The main body 100 may include a lower main body 120 and an upper main body 110.

The lower body 120 is supported from the bottom, and a drive shaft 130 that rotates at reduced speed by the motor 1001 is protruding from the upper surface of the lower body 120. When the juice unit 200 is coupled to the drive shaft 130, the lower rotation shaft 234 of the screw 230 is inserted to transmit the rotational force of the drive shaft 130 to the screw 230.

A power cable 102 is connected to one side of the lower part of the lower body 120 to receive power from the outside. Inside the lower body portion 120, a motor 1001 driven from an external power source and a speed reduction unit 1002 formed of a plurality of gears to reduce the rotational speed of the motor 1001 and transmit it to the drive shaft 130 may be formed. there is.

The upper main body 110 is formed to protrude upward from one side of the lower main body 120 and supports the outer surface of the juicer 200 when the juicer 200 is coupled to the lower main body 120. . A control button 104 may be formed on the outer surface of the upper main body 110 to control the operation of the juicer.

As shown, a rotation prevention key 112 may be formed on the inner surface of the upper main body 110 to protrude to a predetermined length in the longitudinal direction. A rotation prevention key groove 2159 into which the rotation prevention key 112 is inserted is formed on the outer surface of the hopper 210 to correspond to the rotation prevention key 112. The rotation prevention key groove 2159 may be formed integrally below the interference prevention groove 2154 as shown in FIG. 5.

When the juice extraction unit 200 is coupled to the main body 100, the rotation prevention key 112 is inserted into the rotation prevention key groove 2159 and coupled. Therefore, the circumferential position of the hopper 210 can be fixed by the combination structure of the rotation prevention key groove 2159 and the rotation prevention key 112. In addition, when juice material is caught in the cut portion 225 and a load is applied, the hopper 210 receives a force that rotates in the direction opposite to the direction of fastening with the juice drum 280, resulting in fastening between the juice drum 280 and the hopper 210. This can be released, and this is prevented by preventing rotation of the hopper 210 by the coupling structure.

As described above, in the present invention, for the safety of the user, the hopper 210 cannot be attached to the upper part of the juice drum 280 when only the juice drum 280 is seated on the main body 100, and the juice drum 280 The juice extraction unit 200 can be coupled to the main body 100 only when the hopper 210 is attached. The hopper 210 and the juice drum 280 are fixed by a combination between the coupling protrusions 2174 and 2801. When only the juice drum 280 is seated on the main body 100, the coupling protrusions 2174 If an attempt is made to couple the juice drum 280 and the hopper 210 by rotating the binding protrusion 2801, the positions of the anti-rotation key groove 2159 and the anti-rotation key 112 do not match, so they do not engage. In addition, when fixing the hopper 210 to the upper main body 110 by aligning the positions of the rotation prevention key groove 2159 and the rotation prevention key 112, the coupling protrusion 2174 and the coupling protrusion 2801 are aligned and coupled to each other. The binding protrusion 2174 and the binding protrusion 2801 are located so that it is impossible. Therefore, in the present invention, the juicer 200 can be coupled to the main body 100 only when the hopper 210 is coupled to the upper part of the juice drum 280.

In the above-described embodiment, the upper body 110 supporting the outer surface of the juicer 200 is formed in the main body 100, and the rotation prevention key 112 and the hopper 210 are formed in the upper main body 110. ), the rotation prevention key groove 2159 is formed to prevent loosening between the hopper 210 and the juice drum 280 due to reverse rotation of the hopper 210 during juice extraction. At this time, if the main body 100 does not have an upper main body 110 that supports the outer surface of the juicer 200, a separate loosening prevention part is required to prevent the hopper 210 from rotating in the reverse direction during juicing and being released. do. Hereinafter, various embodiments of the loosening prevention portion will be described with reference to FIGS. 51 to 56.

First, as shown in FIG. 51, a movable binding portion 401 that moves up and down within the juice drum 280 may be formed. A housing may be formed in the juice drum 280 to form a space in which the movable fastener 401 can move up and down separately outside the space in which the screw 230 is mounted.

The movable fastener 401 may be formed in the shape of a long bar. When the movable fastener 401 moves upward, the upper end of the movable fastener 401 is formed at the upper guide hole 406 of the juice drum 280. ) and may protrude onto the juice drum 280.

At this time, the upper end of the movable fastener 401 protruding above the juice drum 280 is inserted into the fastener groove 402 formed on the bottom of the hopper 210, so that even if a force in the reverse direction is applied to the hopper 210, the hopper ( 210) rotation can be prevented.

A movement guide protrusion 404 protruding upward may be formed on the upper surface of the main body 100 where the drive shaft 130 protrudes. In addition, an insertion groove 403 into which the moving guide protrusion 404 is inserted may be formed on the bottom of the juice drum 280 to correspond to the moving guide protrusion 404. In addition, a lower guide hole 405 into which the lower end of the movable fastening portion 401 is inserted may be formed connected to the upper part of the insertion groove 403. Accordingly, when the movable fastener 401 moves downward, the lower end of the movable fastener 401 may be inserted into the lower guide hole 405 and protrude downward into the insertion groove 403.

To describe the shape of the movable fastener 401 in more detail, as shown in FIG. 51, the axial position of the upper guide hole 406 into which the upper end of the movable fastener 401 is inserted and the movable fastener 401 ), the axial positions of the lower guide holes 406 into which the lower ends are inserted are different from each other, so the movable fastening portion 401 generally has a long bar shape, but may have a shape that is bent or curved in the middle.

At this time, steps 4011 and 4012 protruding in the radial direction are formed on the upper outer surface and the lower outer surface of the movable fastening part 401, thereby limiting the position at which the movable fastening part 401 moves up and down.

When the movable fastener 401 moves upward, the step 4011 formed at the upper end of the movable fastener 401 contacts the spring 407 interposed between the bottom surface of the upper guide hole 406 and the step 4011. By doing so, the upward movement of the movable fastener 401 can be restricted. In addition, when the movable fastener 401 moves downward, the step 4012 formed at the lower end of the movable fastener 401 comes into contact with the upper surface of the lower guide hole 406, so that the lower part of the movable fastener 401 Movement may be restricted.

As shown, in this embodiment, the step 4012 formed at the lower end of the movable fastener 401 is formed together with the bent portion of the movable fastener 401.

In addition, a step 4013 is formed under the lower end of the movable fastener 401 inserted into the lower guide hole 406 by changing the diameter of the movable fastener 401, and the lower inner surface of the lower guide hole 406 Also, by forming a step 4051 protruding inward to correspond to the step 4013, the lower movement of the movable coupling portion 401 can be restricted by contact between the two steps 4013 and 4051.

As shown in (a) of Figure 51, when the juice unit 200 is coupled to the main body 100 in the correct position, the moving guide protrusion 404 is inserted into the insertion groove 403. At this time, the moving guide protrusion 404 is inserted into the insertion groove 403. It contacts the bottom of the movable fastener 401 located in the insertion groove 403 and pushes the movable fastener 401 up so that the movable fastener 401 moves upward. At this time, the upper end of the movable binding portion 401 inserted into the upper guide hole 406 protrudes above the juice drum 280 and is inserted into the binding groove 402 formed on the bottom of the hopper 210, thereby forming the juice drum 280. and the hopper 210 can be connected.

As shown in (b) of Figure 51, when the juice unit 200 is separated from the main body 100, the contact between the movable guide protrusion 404 and the movable fastener 401 is released, and the movable fastener 401 is connected to the spring. The lower end of the movable binding portion 401, which was inserted into the lower guide hole 405 by moving downward again due to the elastic force caused by (407), is again located within the insertion groove 403, and protrudes above the juice drum 280. The upper end of the movable fastening part 401 is again located inside the upper guide hole 406. Therefore, the binding between the juice drum 280 and the hopper 210 by the movable binding unit 401 is released, and the hopper 210 or the juice drum 280 is rotated to connect the juice drum 280 and the hopper 210. can be separated.

Next, another embodiment of the loosening prevention portion will be described with reference to FIG. 52.

In this embodiment, an elastic coupling portion 411 that elastically moves toward the handle portion 216 is formed on the inner side of the handle portion 216 formed in the hopper 210. That is, the spring 412 is interposed between the elastic fastening portion 411 and the handle portion 216, so that the elastic fastening portion 411 can elastically move toward the handle portion 216 in a button manner.

At this time, the lower end of the elastic binding portion 411 is bent toward the outer surface of the juice drum 280, and the lower end of the elastic binding portion 411 is inserted into the binding groove 413 formed on the outer surface of the juice drum 280. It can be.

As shown in (a) of FIG. 52, when the juice drum 280 and the hopper 210 are coupled in place, the elastic fastening portion 411 can elastically move toward the juice portion 200. At this time, The lower end of the elastic fastening portion 411 can be inserted into the fastening groove 413 to fasten the juice drum 280 and the hopper 210.

In addition, as shown in (b) of FIG. 52, when the user holds and presses the elastic fastener 411, the elastic fastener 411 moves toward the handle portion 216, and at this time, elastic force is stored in the spring 412. It can be. As the elastic coupling portion 411 moves toward the handle portion 216, the coupling between the lower end of the elastic coupling portion 411 and the coupling groove 413 is released, and the juice drum 280 is formed by the elastic coupling portion 411. The binding between the hopper 210 and the hopper 210 is released, and the hopper 210 or the juice drum 280 can be rotated to separate the juice drum 280 and the hopper 210.

Next, another embodiment of the loosening prevention portion will be described with reference to FIG. 53.
