Drum holes 260 are formed in the lower center of the second module 20 of the juice drum 200. The drive shaft is inserted into the drum hole 260 and connected to the screw 300, and can transmit power to the screw 300. The inner circumferential surface of the drum hole 260 may have a shape corresponding to the shape of the drive shaft so as to receive a rotational force from the drive shaft.

The screw (300) receives rotational force from the drive shaft and rotates, and presses or crushes the juice object. A plurality of screw spirals 310 are formed in a portion of the screw 300 that contacts the juice drum 400. The juice is squeezed by a narrow gap between the screw 300 and the juice drum 400 by the screw thread 310 and is conveyed downward.

The juice drum 400 has a hollow cylindrical or frusto-conical shape and can be squeezed or crushed by interaction with the screw 300.

The juice drum 400 according to one embodiment of the present invention may include a first module 10 and a second module 20. The juice drum 400 may be constituted by a combination of the first module 10 and the second module 20.

The first module 10 may be generally cylindrical in shape and open on the upper and lower sides. The first module 10 may include a plurality of first comb bars 11 and a plurality of first slits 12 may be formed by a plurality of first comb bars 11.

2 and 3, the width of the first slit 12 on the upper side may be smaller than the width of the first slit 12 on the lower side. Also, the width of the first slit 12 may be made narrower toward the upper side. In addition, the first slit 12 may have a step 121 formed thereon. The width of the first slit 12 on the upper side relative to the step 121 may be smaller than the width of the first slit 12 on the lower side. The first slit 12 may be continuously formed from the upper side of the first module 10 to the lower side.

2A, the first rib 13 and the second rib 14 may be formed on the inner circumferential surface of the first comb- As the screw 300 rotates, the material can be squeezed or crushed by the interaction of the screw spiral 310 and the first rib 13. If the first rib 13 is not provided, the juice may not go down and may be stagnated, or may not be pressed or crushed. The second rib 14 may perform a function of reinforcing the first module 10 and may guide the juice object into the juice drum 400. In addition, the second rib 14 may adjust the position of the screw 300 and adjust the juice space.

2B, the plurality of first comb-teeth bars 11 may include a first comb-like bar 11 having a relatively narrow width and a first comb-like bar 11 having a relatively wide width . The first ribs 13 are formed on the inner circumferential surface of the first comb-like rod 11 having a relatively narrow width and the second ribs 14 can be formed on the inner circumferential surface of the first comb- have.

On the other hand, comb teeth protrusions 22 are formed on the inner peripheral surface of the second module 20 and the comb teeth protrusions 22 can be inserted into the first slits 12 between the first comb teeth bars 11. A predetermined gap can be formed by inserting the comb teeth protrusion 22 into the first slit 12. The juice is discharged through the gap and the debris is separated inside the first module 10 of the juice drum 400 and the juice can be separated and discharged to the second module 20 side.

As can be seen from FIG. 2A, the cross-section of the first comb-teeth rod 11 may have a wider width toward the radially inner side of the first module 10. Accordingly, when the first module 10 and the second module 20 are engaged, a gap is formed in the lower outer circumferential surface of the first module 10, so that the juice can be smoothly discharged.

A first flange 16 may be formed on the lower side of the first comb-like bar 11. The first flange 16 supports the width of the first slit 12 between the plurality of first comb-bars 11 to be fixed. Since the lower end of the first module 10 is rotatably supported, the width of the first slit 12 does not change during the juicing process.

Also, as shown in FIG. 2B, the first step 17 may be formed on the lower side of the first comb-like rod 11. 2A, the second step 26 may be formed below the comb teeth 22 of the second module 20. The first step 17 can be seated and supported in the second step 26 of the second module 20 and the second step 26 can be slightly protruded radially inward The bottom surface of the first module 10 may be positioned so that it does not abut the inner bottom surface of the second module 20. In this case,

As shown in FIGS. 2A and 2B, debris discharge holes 18 and 110 may be formed on the lower side of the first module 10.

Further, as shown in FIG. 2B, the debris discharge hole 110 may further include a debris discharge controller 111 and may be hinged to the first module 10. The debris discharge regulator 111 is composed of packing so that debris can be pushed out of the debris discharge regulator 111 and discharged through the debris discharge port 230 during the juicing process. The debris discharge adjuster 111 is hinged to the debris discharge hole 110 when the first module 10 is cleaned so that the debris that can be caught in the debris discharge hole 110 lifts the debris discharge adjuster 111 As shown in FIG.

The second module 20 of the present invention is configured so as to surround the first module 10 without a slit formed on the main surface thereof. At this time, a juice outlet 220 and a debris outlet 230 are formed below the second module 20. The juice outlet (220) and the juice outlet (230) may be formed in a pipe shape so that juice and debris can be easily discharged. A drum hole 260 is formed in the lower center of the second module 20. The drive shaft may be inserted into the drum hole 260 to transmit power to the screw 300.

Also, as shown in FIG. 1B, the first screw packing 330 may be coupled to the outer circumferential surface of the screw shaft 320. The first screw packing 330 seals the outer peripheral surface of the drum hole 260 when the screw shaft 320 is inserted into the drum hole 260. Accordingly, the juice can be prevented from flowing into the drum hole 260 during the juicing process.

Further, a packing groove (340) may be formed on the lower outer circumferential surface of the screw (300), and a second screw packing may be coupled to the packing groove (340). The second screw packing seals the inside of the seat portion when the packing groove 340 is seated in the seat portion formed inside the second module 20. Accordingly, it is possible to prevent the debris from flowing into the juice outlet 220 during the juicing process.

One embodiment of the second module 20 will be described in more detail with reference to Figs. 1A and 2A. The comb teeth protrusion 22 may be formed on the inner peripheral surface of the second module 20. A slit is not formed on the inner circumferential surface of the second module 20 according to one embodiment of the present invention. That is, the inner peripheral surface of the second module 20 is constituted by a continuous surface.

The comb teeth protrusion 22 of the second module 20 is inserted into the first slit 12 of the first module 10 when the first module 10 and the second module 20 are coupled. A predetermined gap can be formed by inserting the comb teeth protrusion 22 into the first slit 12. The size of the gap may be constant or non-constant. The juice is discharged through the gap and the debris is collected in the second module 20 in the lower part of the inner side of the first module of the juice drum 400 and discharged through the debris discharge port 230 formed on the lower side of the second module 20 .

2A, the width of the comb-like projections 22 on the upper side of the second module 20 may be smaller than the width of the comb-like projections 22 on the lower side. Further, the width of the comb teeth protrusion 22 may become narrower toward the upper side. The stepped portion 24 may be formed on the comb tooth protrusion 22. The width of the upper comb-like projection 22 may be smaller than the width of the lower comb-like projection 22 with respect to the stepped portion 24. Furthermore, the width of the comb teeth 22 on the upper side of the stepped portion 24 may become narrower toward the upper side.

The pressure is applied to the lower side of the juice drum 400 in the pressing process so that the juice drums 400 formed between the slits 12 of the first module 10 and the comb teeth 22 of the second module 20 400 are preferably narrower on the lower side. For example, when the width of the first slit 12 between the first comb-like bars 11 on the upper side is constant and the width of the comb-shaped projections 22 on the upper side of the stepped portion 24 becomes narrower toward the upper side The size of the gap may be increased toward the upper side with respect to the stepped portion 24.

In the case of a hard juice object such as a carrot, the juice may be discharged through a gap formed in the lower part in the compression process. In the case of a juicy object such as tomato, the juice may be discharged not only in the gap formed in the lower side but also in the gap formed in the lower side during the pressing process, as the object to be juiced is raised to the upper wide gap. As described above, when the size of the gap is not constant, the juice efficiency can be improved for both the hard juice object such as carrot and the juice object such as tomato juice. The size of the gap can be kept constant without changing during the juicing process. In addition, in the case of a juicy juice such as a carrot, the juice can be accumulated in the gap during the juicing process. In this case, the object to be juiced is caught by the stepped portion 24, and the object to be juiced can be prevented from accumulating in the gap.

Meanwhile, it is preferable that the first ribs 13 formed on the inner circumferential surface of the first comb-teeth rod 11 are formed adjacent to the first slits 12 (not shown). When the first rib 13 is formed adjacent to the first slit 12, the debris is less caught in the gap than in the case where the first rib 13 is formed at the center portion of the first comb-like bar 11. That is, when the first ribs 13 are formed adjacent to the first slits 12, the pressing force applied to the gaps in the process of passing the juice over the first ribs 13 is reduced, so that debris is caught in the gaps Can be reduced.

1A, the key protrusion 25 can be formed on a part of the inner circumferential surface of the second module 20, and the key groove 15 can be formed on the outer circumferential surface of the first module 10, The coupling position of the module 10 and the second module 20 can be fixed.

Also, in order to fix the coupling position of the first module 10 and the second module 20, a relatively narrow space and a relatively wide space may be formed between the plurality of comb teeth protrusions 22. [ The first comb-teeth rod 11 having a relatively large width can be inserted into a space having a relatively large space between the plurality of comb-teeth projections 22.

As described above, according to the embodiment of the present invention, by constituting the juice drum 400 composed of two modules, the washing is simple and the juicing efficiency can be improved.
