Description

Juicer {JUICER}

The present invention relates to a juicer, and more particularly, to a juicer screw used in a juicer to produce juice juice by pressing and crushing vegetables or fruits, and a juicer using the same.

For health, green juice or juice is often made and eaten at home, and for this purpose, a number of devices have been disclosed that allow the juice to be extracted simply by using vegetables or fruits at home.

Conventionally, the juicer puts the material in the inlet and crushed it by a blade rotating at a high speed to make juice by centrifugation. However, such juicers may destroy the taste and nutrients inherent in ingredients during high-speed crushing, and it was difficult to make green juice with vegetables made of stems or leaves, and it was difficult to make juice with fruits such as kiwi or strawberry with high viscosity. No, it was impossible at all to make soy milk from soybeans.

In order to solve this problem, Korean Patent Registration No. 10-0793852 is a method of compressing and crushing material between a mandrel and a screw rotating at a low speed, and using the principle of grinding and pressing beans into soy milk. There is an effect of making juice by grinding and pressing fruits with high viscosity, such as tomatoes, kiwis, and strawberries, on a steel plate, so that the problem of the conventional juicer as described above could be solved.

However, even in this case, due to the size of the screw and the size of the input port that is manufactured so that the material of an appropriate size is injected according to the size of the screw, there is an inconvenience of having to cut the material in advance before putting the material into the input port.

Accordingly, Korean Patent Registration No. 10-1270140 increases the size of the inlet port and pre-crushes the large material by the crushing part and the crushing part to supply the crushed material to the eccentric side of the screw. Larger ingredients can be juiced without increasing their size.

However, even in this case, since the structure of the conventional juicer that fixedly supports the upper and lower ends of the screw rotation shaft, the inlet port for inputting the large material is in a shape that protrudes outward from an eccentric position to one side of the screw. As a result, there was a problem that the shape of the juicer became large and complicated, and furthermore, the configuration of crushing the material before juice, such as the crushed part and the crushed part, became complicated.

In addition, when debris accumulates on the lower surface of the screw during the juice process, a strong pressure is generated to move the screw in the vertical upward direction. When the screw moves upward, the durability of the juicer decreases due to vibration, and further, the separation distance between the net drum and the screw is changed, so that the juice efficiency may drop rapidly. In particular, in a structure in which the upper and lower ends of the screw are not fixedly supported but only the lower end is supported as in the present invention, a structure to prevent the screw from rising is required.

1 is a cross-sectional view of a juicer according to an embodiment of the present invention.

The juicer according to an embodiment of the present invention may be configured to include a main body 100, a housing 200, a screw 300, and a juice drum 400.

The main body 100 is supported from the bottom surface and a driving unit 110 for rotating the screw 300 may be disposed therein. The driving unit 110 may be composed of a motor and a reducer, but may be composed of only a low-speed motor without a reducer. Unlike the conventional blender that finely crushes the material by rotating the rotating blade at high speed, in the present invention, the juicer and the juicer to perform juice by separating the juice and the debris by rotating the screw 300 at a low speed to compress and crush the material Since it is related, the screw 300 is rotated at a low speed.

At this time, the drive shaft 120 of the motor protrudes from the top of the main body 100, the drive shaft 120 is coupled to the screw 300 to rotate the screw 300.

The housing 200 has an overall shape of a container and is attached to an upper portion of the main body 100, and may accommodate a screw 300 and a juice drum 400 to be described later. The housing 200 may be formed in a form in which the upper surface of the housing 200 is entirely open, and material may be introduced into the housing 200 through an inlet 230 which is an open upper surface. Accordingly, as shown, a material having a size larger than the radius of the screw 300 may also be introduced into the housing 200. Although not shown, a lid (not shown) for opening and closing the upper inlet 230 of the housing 200 may be formed. A separate injection hole may be formed in the lid to limit the size of the material injected into the housing 200 to be larger than the radius of the screw 300 but within a predetermined range.

In the center of the bottom of the housing 200, a waterproof cylinder 240 having a through hole 242 is formed to protrude upward, and a lower rotation shaft 350 of the screw 300 to be described later is inserted through the through hole 242 It may be coupled to the drive shaft 120 under the housing 200. The waterproof cylinder 240 is formed to protrude upward to prevent juice from flowing into the driving unit 110 through the through hole 242. In addition, a packing ring (not shown) formed of a material such as rubber or silicone is inserted at the edge of the through hole 242 to more effectively prevent the juice from flowing into the body 100.

A screw 300 is disposed at the lower end of the housing 200, and as shown, the upper inner side of the housing 200 located above the screw 300 waits before the material input from the inlet 230 is juiced. To form an atmospheric space.

In addition, a juice outlet 250 for discharging the juice juiced from the material inside the housing 200 and a waste outlet (not shown) for discharging the remaining waste are formed to be spaced apart from the lower end of the housing 200.

As described later, the juice flowing out of the juice drum 400 through the outlet hole of the juice drum 400 flows to the juice outlet 250 communicating with the bottom of the housing 200 and is discharged, and separated by juice. The remaining waste may be discharged to the outside of the juice drum 400 through the bottom or one lower side of the juice drum 400 and finally discharged from the waste outlet of the housing 200 in communication therewith.

The screw 300 is disposed at the lower end of the housing 200, the shaft hole 351 of the lower rotation shaft 350 extending downward from the inner center of the screw 300 to the drive shaft 120 of the above-described body 100 By inserting into the screw 300 can be mounted.

In the present embodiment, the housing 200 has the screw 300 disposed therein, and the juice outlet 250 and the waste outlet are attached to the lower housing 210 and the lower housing 210 formed outside the lower end. It may be formed separated by an upper housing 220 that forms a space in which the material inputted from the open inlet 230 stays.

At this time, a pressing step 222 or a pressing protrusion 224 is formed at the lower end of the upper housing 220 as shown, and the juice is disposed inside the lower housing 210 when it is fastened to the lower housing 210. The drum 400 is pressed down to fix the position of the juice drum 400. In FIG. 1, the pressing step 222 supports the upper edge side and the upper surface of the inner module 410 constituting the juice drum 400 and presses it downward, so that the pressing protrusion 224 protrudes downward to juice the juice. It is formed to press the upper edge of the outer module 450 constituting the drum 400 in a downward direction, but is not limited thereto and may be modified in various forms.

In addition, one or more crushing latches 270 protruding in the vertical direction may be formed on the inner side of the upper housing 220 along the circumferential direction of the inner side. As will be described later, the screw 300 according to the present invention may be formed in a shape in which the screw thread 320 extends above the screw body 310. At this time, the end of the screw thread 320 extending above the screw body 310 is located at the lower end of the upper housing 220. At this time, even if a material having a large size such as an apple or orange in a state that has not been cut in advance is introduced into the upper housing 220, the screw thread 320 extending over the screw body 310 rotates and the upper housing 220 The material can be effectively crushed by interaction with the crushing locking projection 270 protruding in the longitudinal direction along the inner surface. That is, the material can be crushed by pressing and mutual cutting according to rotation of the screw thread 320 extending above the screw body 310 in a state in which the material having a large size is caught by the crushing locking projection 270. At this time, when the screw 300 rotates, the pulverized materials can be easily moved under the screw 300 along the surface of the screw thread 320 inclined downward.

In the present embodiment, a case where the crushing protrusion 270 is formed on the upper housing 220 is described as an example when the housing 200 is separated into the upper housing 220 and the lower housing 210, As will be described later with reference to FIG. 19, the housing 200 may be integrally formed without being separated into the upper housing 220 and the lower housing 210. Also in this case, a crushing locking jaw 270 protruding in the longitudinal direction along the circumferential direction of the inner surface of the housing 200 may be formed, and the crushing locking jaw 270 may extend to the upper portion of the screw body 310. In order to interact with the screw thread 320, the lower end of the crushing locking jaw 270 is formed to extend to the upper end of the screw 300 where the screw thread 320 extending above the screw body 310 is located. desirable.

In this case, the direction of the crushing locking protrusion 270 is preferably formed to protrude vertically below the inner surface of the housing 200, but may be formed to be inclined at a predetermined angle. In addition, when the plurality of crushing locking projections 270 are formed along the inner surface of the housing 200, each inclination angle may be formed differently.

The screw 300 is disposed at the lower end of the housing 200 to receive power from the drive shaft 120 of the main body 100 and rotates at a low speed around the rotation axis, and between the juice drum 400 and the screw 300 to be described later. The located material is moved to the lower side, and the juice is pressed and pulverized by interaction with the juice drum 400 to perform juice.

A lower rotation shaft 350 protruding downward is formed under the screw 300, and as described above, the lower rotation shaft 350 is coupled to the drive shaft 120 of the motor to perform rotational motion. In this case, a shaft hole 351 into which the drive shaft 120 is inserted is formed in the lower rotation shaft 350, and the screw 300 may be coupled to the drive shaft 120. Preferably, it is formed as a square shaft hole 351 so that the coupling between the drive shaft 120 and the screw 300 can be firmly formed, and accordingly, the drive shaft 120 is preferably formed as a square shaft.

Hereinafter, various embodiments of the screw 300 according to the present invention will be described in more detail with reference to FIGS. 2 to 11.

2 and 3 are perspective views of the screw according to the first embodiment of the present invention shown in FIG. 1, FIG. 4 is a plan view of FIG. 2, and FIG. 5 is a side view of FIG. 2 taken from various angles, and FIG. 6 Is a perspective view of a screw according to a modified example of FIG. 2, FIG. 7 is a plan view of FIG. 6, FIG. 8 is a side view of FIG. 6 viewed from various angles, and FIG. 9 is a perspective view of a screw according to another modified example of FIG. And FIG. 10 is a plan view of FIG. 9, and FIG. 11 is a side view of FIG. 9 taken from various angles.

The screw 300 may be formed including a screw body 310 and a screw thread 320 protruding in a spiral shape on the outer surface of the screw body 310.

As shown, the screw body 310 may be divided into an upper portion and a lower portion centering on a portion having the largest radius of the screw 300 as shown. The lower portion of the screw body 310 is formed such that the radius gradually decreases as it goes downward, and the radius decreases as it goes downward, thereby forming a space in which the waste separated by juice is located. However, the lower shape of the screw body 310 is not limited thereto, and for example, it may be formed in a straight line downward without a change in radius.

In addition, the upper portion of the screw body 310 is formed so that the radius gradually decreases as it goes upward, and the width of the change in the radius according to the height change is larger than that of the lower portion of the screw body 310 as shown. The uppermost end of the screw body 310 is formed to have the smallest radius and gradually increase in radius as it goes downward.According to this shape, a material having a large size is gradually reduced in size by compression and pulverization and can be transferred. It forms a space. In other words, since the diameter of the upper portion of the screw body 310 gradually increases as it goes downward, the size of the space through which the material formed by the screw body 310 together with the screw thread 320 is transported gradually increases along the transport direction of the material. Becomes smaller. That is, the material is compressed and pulverized by the rotation of the screw 300 to gradually decrease in size and move under the screw 300 along the transfer space gradually decreasing along the screw thread 320 formed in the downward direction. It is done.

The screw thread 320 is formed protruding from the outer circumferential surface of the screw body 310 in the form of a spiral, by which the object of juice is compressed into a narrow gap between the screw 300 and the juice drum 400 by the screw thread 320 It is transferred to the lower side. At this time, the screw thread 320 is preferably protruded to contact or close to the juice drum 400 or the housing 200. As described above, since the upper portion of the screw body 310 has a smaller radius as it goes upward, the protruding height of the screw thread 320 is formed to increase toward the upper portion of the screw body 310.

Screw thread 320 may be formed in one or a plurality, in the present invention, any one thread is formed extending upward of the screw body 310 in the form of a spiral as shown (hereinafter,'the first screw thread ( 320-1) is called'extended part'). Therefore, since the screw body 310 does not exist at the height at which the extension of the first screw thread 320-1 is formed, the size is larger than the radius of the screw 300 even when considering the extension of the first screw thread 320-1. A space in which a large material is located can be formed, and when the screw 300 rotates in the space, the extension of the first screw thread 320-1 and the crushing locking protrusion 270 formed on the inner surface of the housing 200 ), the material can be crushed. At this time, since the surface of the screw thread 320 is formed to be inclined downward, the crushed material is transported downward along the screw thread 320 and juice is performed at the lower end of the screw 300.

As described above, in the present invention, it is not necessary to support the upper rotation shaft on the screw 300 by supporting only by the lower rotation shaft 350, away from the conventional structure for supporting and rotating both ends of the rotation shaft of the screw 300. Therefore, the entire space on the screw 300 can be utilized, and thus, a material having a large size can be directly injected through the inlet 230 on the screw 300 to perform juice. However, in this case, compared to the support structure at both ends of the screw rotation shaft, the screw can easily move upward during the pressing process, and the present invention proposes several embodiments for preventing the screw from moving upward. This will be described later with reference to FIGS. 15 to 18.

At this time, as shown in FIGS. 2 to 5, the shape of one end of the extension part of the first screw thread 320-1 is the opposite direction in which the first screw thread 320-1 extends above the screw body 310 It is formed in the shape of a concave arc, and as a whole, the first screw thread 320-1 at the top may have a hook shape.

In addition, as shown in FIGS. 6 to 8, one end of the extended portion of the first screw thread 320-1 is formed in a straight line, so that the first screw thread 320-1 at the upper end has a semicircular shape as a whole. There can be.

Further, as shown in FIGS. 9 to 11, the shape of one end of the extension part of the first screw thread 320-1 is in a direction in which the first screw thread 320-1 extends above the screw body 310. It is formed in the shape of a convex arc, and as a whole, the first screw thread 320-1 at the top may have a cotyledon shape.

In addition, as shown, a second screw thread 320-2 formed in a spiral shape starting from the top of the screw body 310 and downward may be formed, and the first screw thread of the lower part of the screw body 310 Another plurality of threads 320-3 may be formed between the second screw threads 320-1 and the second screw threads 320-2. Therefore, the width between the adjacent screw threads 320 formed in the screw body 310 is formed to have a relatively wide gap in the upper portion of the screw body 310, and a plurality of screws are formed in the lower portion of the screw body 310 It is formed to have a relatively narrow gap by the threads (320-1, 320-2, 320-3). That is, the upper side of the screw 300 mainly performs a function of crushing a large sized juiced object, and the lower side of the screw 300 may mainly perform a juice function by crushing and pressing.

In addition, a plurality of debris guide jaws 330 protruding outside the radius of the lower end of the screw body 310 may be formed in a circumferential direction. When the screw 300 rotates, the remnant guide 330 performs a function of sweeping the remnants separated by juice and transferred to the lower side of the juice drum 400 to the lower side. In this way, by the dregs guide 330 formed on the outer circumferential surface of the lower end of the screw 300, the dregs caught under the juice drum 400 may be smoothly removed, thereby further increasing the juice efficiency.

Again, referring to FIG. 1, when the juice drum 400 is described, the juice drum 400 is coupled to the housing 200 in the housing 200 and accommodates the screw 300 therein. That is, the juice drum 400 is located between the housing 200 and the screw 300. The material input from the inlet 230 and located on the upper part of the housing 200 crushes the material through the interaction of the first screw thread 320-1 and the crushing protrusion 270 and is transferred downward. Next, the material located between the juice drum 400 and the screw 300 is compressed and crushed while being transported down along the screw 300. The juice juiced in this process is discharged to the outside of the juice drum 400 through an outlet hole formed in the juice drum 400 and finally discharged through the juice outlet 250 of the housing 200, and the juice separated from the juice is It is transferred to the space under the juice drum 400 and finally discharged through the waste outlet of the housing 200.

Hereinafter, the juice drum 400 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 12 to 14.

12 and 13 are exploded perspective views of the juice drum shown in FIG. 1, and FIG. 14 is a combined perspective view of the juice drum of FIGS. 12 and 13;

As shown, the juice drum 400 according to the present invention may be configured by a combination of the inner module 410 and the outer module 450. Here, the inner module 410 and the outer module 450 may be made of a material such as polyetherimide (PEI).

The inner module 410 may have a generally cylindrical shape and may have upper and lower sides open. Here, the inner module 410 includes a plurality of inner plate portions 411 and a plurality of slits 412 are formed by the plurality of inner plate portions 411.

Here, the plate portion is named for convenience for explanation of the design, and when it is divided into a hole portion in which the slit 412 is formed and a plate portion in which the slit 412 is not formed in the cylindrical module, the plate portion in which the slit 412 is not formed It is defined as "distributor."

In this case, the width of the slit 412 on the upper side of the slit 412 may be smaller than the width of the slit 412 on the lower side. That is, the width of the slit 412 may be narrower as it goes upward. In addition, as illustrated in FIG. 12, a step portion 413 may be formed in the slit 412. A width of the upper slit 412 may be smaller than the width of the lower slit 412 based on the stepped portion 413.

In addition, a first rib protrusion 420 may be formed on an inner circumferential surface of the inner plate portion 411. The first rib tuck 420 compresses or crushes the material by interaction with the screw thread 320 according to the rotation of the screw 300. If the first rib tuck 420 is not present, the juiced object may be stagnated without going down, or the pressing force or the crushing force may be low or may not occur.

In addition, a second rib protruding 425 may be formed on the inner surface of the inner plate portion 411 in the longitudinal direction. The second rib tuck 425 performs a function of transporting the material injected into the juice drum 400 to the lower portion and crushing the juice object. The second rib tuck 425 may perform a function of reinforcing the rigidity of the inner module 410 and may perform a function of guiding a juice object into the juice drum 400. In addition, the second rib tuck 425 may perform a function of adjusting the position of the screw 300 and adjusting the juice space.

The protruding height of the second rib chin 425 may be formed to have the same height from the top to the bottom of the inner module 410, but is preferably formed in a form that gradually decreases from the top to the bottom of the inner module 410 Can be. In addition, the second rib chin 425 is formed to incline downward from the top to the bottom of the inner module 410, and protrudes toward the screw 300 at an intermediate portion thereof to form a stepped step 426. I can. The stepped portion 426 may be variously modified in its position, number, or protruding height according to the shape of the screw 300 and the design condition of the screw thread 320. The number and arrangement form of the second rib tuck 425 may be variously changed as necessary in consideration of design conditions and efficiency of juice. In the embodiment of the present invention, the formation direction of the second rib tuck 425 has been described as an example that is formed vertically in the vertical direction of the inner module 410, but the scope of the present invention is not limited thereto.

In this case, the first rib jaw 420 is formed on the lower inner surface of the inner plate portion 411, and the second rib jaw 425 is formed entirely below the inner surface of the inner plate portion 411.

Next, the outer module 450 will be described. The outer module 450 is generally cylindrical and includes an outer plate portion 451 whose upper and lower sides are open and a rib 452 protruding from an inner surface of the outer plate portion 451.

The outer plate portion 451 is formed to be detachable (removable) by receiving the inner module 410 therein. That is, when the outer module 450 is coupled to the inner module 410, the outer module 450 may be coupled to receive and surround the inner module 410 inside. In this case, the outer module 450 may wrap and support the inner module 410.

When the outer module 450 and the inner module 410 move up and down and are coupled, the rib 452 is inserted into and coupled to the slit 412 under the slit 412 of the inner module 410. At this time, a slit hole, which is a fine gap formed between the slit 412 and the rib 452, is formed, and the juice generated in the juice drum 400 can be discharged to the outside through the slit hole.

As described above, in this embodiment, the inner module 410, the slit 412 and the outer module 450 of the rib 452 are combined to discharge the juice through the gap between the slit 412 and the rib 452 Because it forms, it is very easy to clean compared to the conventional mesh drum.

At this time, the rib 452 may be formed to correspond to the shape of the slit 412 described above, and the width of the rib 452 is narrower toward the upper side, so that the width of the upper rib 452 is It may be smaller than the width of the rib 452.

In addition, a step portion 453 is formed in the rib 452, so that the width of the upper rib 452 may be smaller than the width of the lower rib 452 based on the step portion 453.

When the outer module 450 and the inner module 410 are moved up and down by the shape of the rib 452 and the slit 412 as described above, when the outer module 450 and the inner module 410 are moved up and down, the width is relatively lower than the relatively large slit 412 By inserting the upper portion of the small rib 452, the outer module 450 and the inner module 410 can be easily coupled.

In addition, a plurality of juice discharge holes 460 may be formed in the outer plate portion 451 along the plate surface of the outer plate.

In this way, the juice formed in the juice drum 400 formed by the combination of the inner module 410 and the outer module 450 is the slit 412 of the inner module 410 and the rib 452 of the outer module 450 It may be discharged to the outside of the juice drum 400 by passing through the slit hole formed therebetween and the juice discharge hole 460 formed in the outer module 450.

At this time, it is preferable that the gap formed between the slit 412 and the rib 452 is formed so that the width of the gap increases in the radial direction to facilitate the discharge of juice. Further, the gap is made to have a smaller width of the gap as it goes downward in the longitudinal direction, so as to prevent the debris generated by being crushed more finely as it goes downwards to be discharged through the gap and to apply strong pressure by the screw 300 It is desirable to support it.

Hereinafter, a structure for preventing the screw from moving upward will be described with reference to FIGS. 15 to 18.

First, a description will be given of a structure for preventing screw upward movement according to a first embodiment of the present invention.

A lower rotation shaft 350 protruding downward from the inside is formed in the lower center of the screw 300. A shaft hole 351 is formed at the lower end of the lower rotation shaft 350 inwardly so that the upper end of the driving shaft 120 is coupled. In this case, it is preferable that the upper end of the drive shaft 120 is formed as a square shaft, and the shaft hole 351 is formed as a square shaft hole. Accordingly, when the drive shaft 120 rotates, it is possible to prevent the drive shaft 120 from spinning and transmit the rotational force of the drive shaft 120 to the screw 300.

A rotation support part 353 is coupled to the outer periphery of the lower rotation shaft 350. At this time, a bearing 3555 is formed between the lower rotational shaft 350 and the rotational support 353, so that the screw 300 can freely rotate with respect to the rotational support 353.

The rotation support part 353 has a hole through which the rotational shaft of the screw 300 passes through the center, and includes an insertion protrusion 3552 and a seating part 3551.

A shaft hole 351 is formed at the lower end of the lower rotation shaft 350 inwardly so that the upper end of the driving shaft 120 is coupled. At this time, it is preferable that the upper end of the drive shaft 120 is formed as a square shaft, and the shaft hole 351 is formed as a square shaft hole. Accordingly, when the drive shaft 120 rotates, it is possible to prevent the drive shaft 120 from spinning, thereby transmitting the rotational force of the drive shaft 120 to the screw 300.

A rotation support part 3601 is coupled to the outer periphery of the lower rotation shaft 350. At this time, a bearing 3564 is formed between the lower rotation shaft 350 and the rotation support part 361, so that the screw 300 can freely rotate with respect to the rotation support part 3601.

The rotation support part 3601 has a hole in the center through which the lower rotation shaft 350 of the screw 300 passes, and may be formed in a circular plate shape covering the lower surface of the screw 300, and around the hole It has a protruding shape and a bearing 3564 may be disposed. A protruding rib 3562 protruding in a radial direction is formed on the rotation support part 361, and the protruding rib 3562 may be formed continuously along the circumferential direction, or may be formed in a protruding shape with a predetermined interval. have. An insertion groove 203 into which the protruding rib 3562 is inserted may be formed on the inner surface of the housing 200.

When coupled to 201, the protruding rib 3562 of the rotation support portion 3601 is positioned in the insertion groove 203 between the lower surface of the second housing 202 and the lower surface of the first housing 201. In this way, while the screw 300 is fixed in the housing 200, the drive shaft 120 is inserted into the shaft hole 351 formed in the lower rotation shaft 350 of the screw 300, so that the drive shaft 120 and the screw 300 are inserted. Combine.

Therefore, the rotational force of the drive shaft 120 can be transmitted to the screw 300 by the coupling between the driving shaft 120 of the square shaft and the lower rotation shaft 350 of the square shaft hole, and a strong rising pressure or falling pressure on the screw 300 When this is applied, it is possible to prevent the upward movement and downward movement of the screw 300 due to the contact between the protruding rib 3562 and the insertion groove 203.

In the following description, the differences will be mainly described as compared to the above-described embodiment with reference to FIGS. 1 to 14.

First, compared to the above-described embodiment, the biggest difference is that in the above-described embodiment, the juice drum 400 is disposed between the housing 200 and the screw 300, but in this embodiment, the juice drum 400 is omitted. Instead, the shape of the screw 300 is modified. In the present embodiment, the screw 300 is configured to be separated and coupled to the first module 360 and the second module 380, hereinafter, in more detail with reference to the drawings for the screw 300 according to the embodiment of the present invention. I will explain it clearly.
