That is, the second drive shaft 154 and the first drive shaft 152 are formed in the form of a concentric double shaft so that the second drive shaft 154 surrounds the outer end of the first drive shaft 152. The upper end of the second drive shaft 154 is formed with a prismatic protrusion 153 protruding into a prismatic shape so as to be inserted and coupled to the prismatic shaft hole 351 formed in the lower rotation shaft 350 of the screw 300, and the lower end is formed with a top cover ( 102). That is, the end of the second drive shaft 154 is also protruded from the upper surface of the drive body 100. At this time, the first bearing 160 is disposed between the inner surface of the top cover part 102 and the second drive shaft 154, and the second bearing 160 is disposed between the inner surface of the second drive shaft 154 and the first drive shaft 152. Since the bearing 162 is disposed, the second drive shaft 154 may be able to rotate relative to the top cover part 102 and the first drive shaft 152. A flange portion 151 extending in a radial direction in a flange shape may be formed at the lower end of the second drive shaft 154, and the flange portion 151 includes an upper shaft of a plurality of third planetary gears 143 to be described later.

Thus, 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 discharge port of the juice housing 200 in communication therewith.

Screw 300 is disposed at the lower end of the juice housing 200, the second drive shaft 154 of the above-described drive body 100 of the lower rotation shaft 350 extending downward from the inner center of the screw 300 The screw 300 can be mounted by inserting it into the shaft hole 351.

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

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 Figure 2, the pressing step 222 is to press the upper edge of the inner module 410 constituting the juice drum 400, the pressing protrusion 224 of the outer module 450 constituting the juice drum 400 It is formed to pressurize the upper surface of the edge, but is not limited thereto and can be modified in various forms.

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 is rotated. 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 compression and mutual cutting according to rotation of the screw thread 320 extending above the screw body 310 in a state in which a 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 easily move under the screw 300 along the surface of the screw thread 320 inclined downward.

In this embodiment, the case where the juice housing 200 is separated into the upper housing 220 and the lower housing 210 is described as an example in which the crushing locking protrusion 270 is formed in the upper housing 220. , As will be described later, the juice 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 juice housing 200 may be formed, and the crushing locking jaw 270 extends to the top of the screw body 310 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 so as to interact with the screw thread 320 It is desirable.

At this time, the direction of the crushing locking jaw 270 is preferably formed to protrude vertically below the inner surface of the juice 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 juice housing 200, each inclination angle may be formed differently.

The screw 300 is disposed at the lower end of the juice housing 200 to receive power from the second drive shaft 154 of the drive body 100 and rotates at a low speed around the rotation shaft. 300) The material located between the material is moved to the lower side, and the juice is pressed and crushed 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 second drive shaft 154 to perform rotational motion. In this case, a shaft hole 351 into which the second drive shaft 154 is inserted is formed in the lower rotation shaft 350, and the screw 300 may be coupled to the second drive shaft 154. Preferably, the second drive shaft 154 and the screw 300 are formed with a square shaft hole 351 so that the coupling between the second drive shaft 154 and the screw 300 can be firmly formed, and accordingly, the second drive shaft 154 is also preferably formed as a square shaft.

Hereinafter, the screw 300 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 11 to 20.

11 and 12 are perspective views of the screw shown in FIG. 1, FIG. 13 is a plan view of FIG. 11, FIG. 14 is a side view of FIG. 11 viewed from various angles, and FIG. 15 is a screw according to a modified example of FIG. FIG. 16 is a plan view of FIG. 15, FIG. 17 is a side view of FIG. 15 taken from various angles, FIG. 18 is a perspective view of a screw according to another modified example of FIG. 11, and FIG. 19 is a plan view of FIG. 18 And FIG. 20 is a side view of FIG. 18 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 so 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, 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 has the smallest radius and is formed to gradually increase the 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 transported. 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 decreases. 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 in the form of a spiral on the outer circumferential surface of the screw body 310, and the juice object 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 juice 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 above the screw body 310 in the form of a spiral as shown (hereinafter,'first screw thread ( 320-1) is called'extended part'). Therefore, the screw body 310 does not exist at the height at which the extension portion of the first screw thread 320-1 is formed, and thus the size is larger than the radius of the screw 300 even when considering the extension portion of the first screw thread 320-1. It is possible to form a space in which a large material is located, and when the screw 300 rotates in the space, the extension portion of the first screw thread 320-1 and the crushing protrusion formed on the inner surface of the juice housing 200 ( The interaction between 270) allows the material to be crushed. At this time, since the surface of the screw thread 320 is formed to be inclined downward, the pulverized 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 design, the structure for supporting the upper rotation shaft on the screw 300 is not required 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. Accordingly, 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.

At this time, as shown in FIGS. 11 to 14, 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. 15 to 17, one end of the extension part of the first screw thread 320-1 is formed in a straight line, so that the first screw thread 320-1 at the top has a semicircular shape as a whole. There can be.

Further, as shown in FIGS. 18 to 20, 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 starting from the top of the screw body 310 and downward may be formed, and a first screw thread at the bottom of the screw body 310 Another plural number of threads 320-3 may be formed between the (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 juice 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 jaw 330 performs a function of sweeping the debris separated by juice and transferred to the lower side of the juice drum 400 to the lower side. In this way, the dregs caught under the juice drum 400 can be smoothly removed by the dregs guide jaws formed on the outer circumferential surface of the lower end of the screw 300 by the dregs guiding jaws 330 to further increase the juice efficiency.

Referring again to Figs. 1 and 2, the juice drum 400 is described, the juice drum 400 is bound to the juice housing 200 in the juice housing 200 and accommodates the screw 300 therein. do. That is, the juice drum 400 is located between the juice housing 200 and the screw 300. The material input from the inlet 230 and positioned on the juice housing 200 is pulverized and transported downward through the interaction of the first screw thread 320-1 and the crushing protrusion 270. Next, the material positioned between the juice drum 400 and the screw 300 is compressed and crushed while being transported downward 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 juice housing 200, and the juice separated from the juice Is transferred to the space under the juice drum 400 and is finally discharged through the waste outlet of the juice 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. 21 to 23.

21 and 22 are exploded perspective views of the juice drum shown in FIG. 1, and FIG. 23 is a combined perspective view of the juice drum of FIGS. 21 and 22.

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. The inner plate portion 411 is a body of the inner module 410 and is formed in a cylindrical shape, and a plurality of slits 412 are spaced apart from each other along the circumference of the inner plate portion 411.

Here, when the cylindrical module is divided into a space portion in which the slit 412 is formed and a plate portion in which the slit 412 is not formed, the plate portion in which the slit 412 is not formed is defined as a “plate portion”.

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 toward the upper side. In addition, as illustrated in FIG. 21, a stepped portion 413 may be formed in the slit 412. The width of the slit 412 on the upper side may be smaller than the width of the slit 412 on the lower side based on the stepped portion 413.

In addition, a first rib protrusion 420 may be formed on the inner circumferential surface of the inner plate portion 411. The first rib tuck 420 compresses or pulverizes 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 object to be juiced 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 transferring the material input 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.

In addition, the second rib tuck 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 stepped portion 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 tuck 420 is formed at the lower end of the inner side of the inner plate portion 411, and the second rib tuck 425 is entirely formed from the upper end to the lower end of the inner side 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 part 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 fine gap is formed between the inner surface of the slit 412 and the rib 452, and the juice generated inside the juice drum 400 can be discharged to the outside through the gap. In other words, the gap serves as an outlet hole.

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 with respect to 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 wide under the slit 412 having a relatively large width. By inserting the upper part 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 fine gap formed therebetween and the juice discharge hole 460 formed in the outer module 450.

At this time, the gap formed between the slit 412 and the rib 452 is preferably formed to increase the width of the gap in the radial direction to facilitate the discharge of juice. Furthermore, 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, and to prevent discharge through the gap, and a strong pressure by the screw 300 It is desirable to support it.
