The juice target is transferred to the lower part by the screw spiral 310 and the juice target is compressed by a narrow gap between the screw 300 and the juice drum 400 . To this end, the spacing between the screw spirals 310 adjacent to the top of the screw 300 may be greater than the spacing between the screw spirals 310 adjacent to the bottom of the screw 300 .

The juicing drum 400 may have a hollow cylindrical or truncated cone shape, and may compress or pulverize a juice target by interaction with the screw 300 .

Hereinafter, the juice drum 400 according to embodiments of the present invention will be described in detail. The juice drum according to embodiments of the present invention includes a first module 10 and a second module 20, and the first module 10 and the second module 20 can be detachably coupled to each other. have.

The first module 10 has a hollow cylindrical shape opened up and down, and includes at least one elongated slit 12 . The slit 12 is formed downward at a position spaced apart by a set distance from the lower portion of the upper end of the first module 10 . The lower end of the slit 12 may be opened or blocked by the reinforcing ring 16 or the like. The second module 20 has a hollow cylindrical shape and includes at least one or more ribs 22 inserted corresponding to the slits 12 formed in the first module 10 . When the second module 20 and the first module 10 are coupled, a predetermined gap is formed between the slit 12 of the first module 10 and the rib 22 of the second module 20, and the material The juice separated from the residue generated when juicing the juice is discharged from the inside of the juice drum to the outside through the gap. That is, the gap between the slit 12 and the rib 22 serves as a mesh hole in the conventional mesh structure.

According to the type of juicer to which the juice drum is applied, the juice drum may have various shapes as shown in FIGS. 1A to 6B . For example, the length of the first module 10 and the second module 20 is similar to that of FIGS. 1A to 4 and FIGS. 6A and 6B, or the length of the second module 20 is similar to that of FIGS. 5A and 5B. It may be formed shorter than the length of the first module 10 . In addition, in the first and second embodiments shown in FIGS. 1A to 4 , the slit 12 is formed to correspond to the entire length of the first module 10 (the length of the slit 12 is longer than the set distance) formed), whereas in the third embodiment shown in FIGS. 5A and 5B , the slit 12 may be formed only in the lower portion of the first module 10 (the length of the slit 12 being shorter than the set distance). . That is, the cylinder 101 having a compression space formed therein is formed on the upper portion of the first module 10 , and the slit 12 may be formed only on the lower portion of the first module 10 . Furthermore, in the fourth embodiment shown in FIGS. 6A and 6B , the slits 12a and 12b are an upper slit 12a formed in the upper portion of the first module 10 and a lower portion formed in the lower portion of the first module 120 . It may include a slit (12b). The upper slit 12a may be positioned more radially outward than the lower slit 12b.

6A and 6B, a first step 103 is formed in the central portion of the first module 10 in the longitudinal direction, and in the central portion of the second module 20 in the longitudinal direction, the A second step 203 corresponding to the first step is formed, so that the first module 10 may be supported by the second module 20 .

In addition, a reinforcing ring 16 is formed on the first step, and the slits 12a and 12b are divided into an upper slit 12a formed in the upper portion and a lower slit 12b formed in the lower portion based on the first step. do.

On the other hand, if the slit 12 is a hole that appears to cross the spiral of the screw 300 when the screw 300 is accommodated in the juice drum, whether a square-shaped hole or an oval-shaped hole is not limited thereto. Also, the rib 22 is inserted corresponding to the slit 12 to form a gap therebetween, and any shape is not limited thereto. The first module includes a hole portion in which the slit 12 is formed and a plate portion in which the slit 12 is not formed along the circumferential direction. In this specification, for convenience, the plate portion 11 in which the slit 12 is not formed is used. referred to as "live".

In the embodiments of the present invention, the first module 10, as can be seen in FIGS. 1a to 6b, is a cylindrical shape with an upper and a lower part open so that the screw 300 can be accommodated therein, and as a whole from the upper part. It may be formed so that the inner diameter gradually decreases as it goes down. In this case, as the screw 300 rotates, the volume between the first module 10 in which the material can be located and the screw 300 decreases from the upper side to the lower side, and the compressive force applied to the material decreases from the upper side to the lower side. will gradually increase. Thus, as the material moves from top to bottom, it is compressed into smaller particles or pulverized. However, the shape and size of the screw 300 may be variously configured in a shape and size in which the compression force applied to the material becomes stronger as it goes downward, and the present invention is not limited to the shape of the embodiments described herein.

As can be seen in Figures 1a to 6b, the second module 20 according to the embodiments of the present invention has the inner diameter of each part of the second module 20 so that it can be coupled by surrounding the first module 10. It may be formed larger than the outer diameter of the corresponding portion of the first module (10). However, the shape of the second module 20 is not limited to the embodiments of the present invention, and the rib 22 is inserted into the slit 12 of the first module 10 so that the rib 22 and the slit 12 are inserted. ) can be any arbitrary shape in which the gap between the screw helices 310 can intersect.

Meanwhile, at least one or more ribs 13 and 14 may be spaced apart along the inner circumferential surface of the first module 10 . The ribs 13 and 14 may be formed in the longitudinal direction of the first module 10 . The ribs 13 and 14 formed on the inner circumferential surface of the first module 10 and the ribs of the second module 20 inserted into the slit 12 of the first module 10 through the previous description and the description to be described later. (22) will be understood to perform different functions.

Without these ribs (13, 14), the juice target does not go down and is stagnant, or the compression or crushing force is low or may not occur. In addition, since the first module 10 may be deformed by the compressive force generated in the process of transporting and compressing the material by the spiral 310 of the screw 300 , the first module 10 may be reinforced with the first module 10 . Ribs 13 and 14 may be formed in (10). In addition, one rib (13, 14) may be formed in one flesh.

In one aspect, the ribs 13 and 14 are formed on the inner circumferential surface of the flesh 11 in which the slit 12 of the first module 10 is not formed, and a rib having a length shorter than or similar to the length of the slit 12 . (13) (hereinafter referred to as "first rib") and a rib ( 14) (hereinafter referred to as “second rib”).

In general, the ribs 13 and 14 serve to allow the material to be introduced into the juice drum 400 to go down by being sandwiched in a narrow portion in contact with the screw 300 . The ribs 13 and 14 may perform a function of squeezing the material together with the screw 300 while making the material go down. Therefore, the ribs 13 and 14 do not necessarily have to be formed in the longitudinal direction of the juice drum 400, and are formed to intersect the spiral 310 of the screw 300 in the longitudinal direction for efficient transport and compression of the material. It may also be implemented in a slanted form having a constant inclination.

At this time, as can also be seen in FIG. 2C , the first rib 13 may be formed at a position adjacent to the slit 12 in the flesh 11 of the first module 10 . When the first rib 13 is formed adjacent to the slit 12, compared to the case where the first rib 13 is formed in the central portion of the flesh 11, debris is reduced in the gap.

On the other hand, the second rib 14 is formed long along the longitudinal direction on the inner circumferential surface of the flesh 11 so as to guide and compress the material, as well as the spiral of the screw 300 . It is possible to perform a reinforcing function to prevent deformation of the first module 10 due to the compression force, and a function of adjusting the receiving position of the screw 300 in the juice drum 400 and adjusting the juice space.

In addition, the protrusion height of the second rib 14 may be configured to have the same height from the top to the bottom, but as can be seen in FIGS. 1A, 2A, 2C, 3A and 4, it is gradually lowered from the top to the bottom, or 2 At least one step having a reduced diameter may be formed in the middle portion in the longitudinal direction of the ribs 14 .

Also, as can be seen in FIGS. 1A, 2A, 2C, 3A and 4 , the plurality of ribs 11 may include a relatively narrow rib 11 and a relatively wide rib 11 . In addition, the first rib 13 may be formed on the inner circumferential surface of the flesh 11 having a relatively narrow width, and the second rib 14 may be formed on the inner circumferential surface of the flesh 11 having a relatively wide width.

Further, when the first module 10 and the second module 20 are combined, the ribs 22 ), instead of forming a means for fixing the first module 10 and the second module 20 may be provided. For example, a coupling groove 19 may be formed on the outer peripheral surface of the relatively wide rib 11 of the first module 10, and the second module facing the relatively wide rib 11 ( A coupling protrusion 29 capable of being coupled to the coupling groove 19 may be formed on the inner circumferential surface of the 20 . Alternatively, a coupling protrusion may be formed on the outer circumferential surface of the relatively wide rib 11 of the first module 10 , and the second module 20 facing the relatively wide rib 11 . A coupling groove capable of being coupled to the coupling protrusion may be formed on the inner circumferential surface. By the coupling of the coupling groove 19 and coupling protrusion 29, the relative position of the second module 20 with respect to the first module 10 is determined and , and thus the size of the gap can be maintained. In addition, the means for fixing the first module 10 and the second module 20 is not limited to the coupling groove and the coupling protrusion described above.

Meanwhile, in the second module 20 , a separation space may be formed between the inner circumferential surface on which the ribs 22 are not formed and the corresponding outer circumferential surface of the first module 10 , or may be brought into contact with each other.

In one aspect, when a separation space is formed between the inner peripheral surface on which the rib 22 is not formed in the second module 20 and the outer peripheral surface of the first module 10 corresponding thereto, the first module 10 and the second module (20) A space is provided for the juice to flow through, so that the juice flows downward without obstruction.

In another aspect, the spaced apart space between the inner peripheral surface where the rib 22 is not formed in the second module 20 and the outer peripheral surface of the first module 10 corresponding thereto so that the juice is collected as it goes down. It can get bigger as you go down.

In another aspect, the outer diameter of the first module 10 to form a spaced space between the inner peripheral surface on which the rib 22 is not formed in the second module 20 and the outer peripheral surface of the first module 10 corresponding thereto It may be configured to gradually decrease from the upper part to the lower part, and at least one step difference of which the outer diameter is reduced may be placed at a central position in the longitudinal direction of the outer peripheral surface of the first module 10 .

Also, as can be seen in FIGS. 1A, 2A, 2C, 3A, and 4, the width of the spokes 11 formed between the slits 12 of the first module 10 (one slit along the circumferential direction and a neighboring slit) The distance between them) may be made to have a shape that generally becomes wider toward the center in the radial direction. In this case, the gap formed between the slit 12 of the first module 10 of the juice drum 400 and the rib 22 of the second module 20 is configured to become wider from the inside in the radial direction to the outside, It is possible to prevent the problem of clogging the gap or obstructing the flow of juice by debris in the process.

In one aspect, in order to increase the width of the flesh 11 toward the center of the radial reflection, the cross section of the flesh 11 formed in the first module 10 may be generally semicircular, oval, or trapezoidal. .

On the other hand, the material is transferred to the lower side by the rotation of the screw 300 inside the first module 10 of the juice drum 400, and the gap between the screw 300 and the inner peripheral surface of the first module 10 is lowered. As it becomes narrower, the material is gradually compressed and the grains become smaller. Accordingly, the lower gap of the juice drum from which the juice is filtered may be formed narrower than the upper gap. In addition, depending on the material, the discharge of the juice through the gap on the lower side may be hindered by the residue generated during the juice extraction process. Accordingly, the upper gap of the juice drum may be formed relatively wider than the lower gap so that the juice overflows through the upper gap. That is, the gap formed between the slit 12 of the first module 10 of the juice drum and the rib 22 of the second module 20 may be configured such that the lower portion is continuously or discontinuously narrowed than the upper portion.

To this end, in one aspect, as can be seen in FIGS. 1A, 1B, 2A, 2C, 3A and 4, the width of the slit 12 of the first module 10 can be made wider toward the lower side and the second The width of the slit 12 of one module 10 may be formed narrower toward the upper side. In another aspect, the width of the slit 12 of the first module 10 may be formed to be constant, and the width of the rib 22 of the second module 20 may be formed narrower toward the upper side.

In another aspect, as can be seen in FIGS. 1A , 1B , 2A , 2C , 3A and 4 , the steps 121 , 221 in the longitudinal central portion of the first module 10 or the second module 20 . and the gap formed between the slit 12 of the first module 10 and the rib 22 of the second module 20 based on the steps 121 and 221 is such that the upper side is wider than the lower side. For this, the width of the rib 22 of the second module 20 may be made narrower toward the upper side based on the step 221 .

On the other hand, the juicing drum 400 may be made of a high-strength material that is strong enough to withstand the pressure generated during the juicing process while being harmless to the human body and to maintain the spacing between the slits 12 . In addition, the juice drum 400 may be made of one thin plate made of a high-strength material.

In one aspect, the first module 10 and the second module 20 may be integrally formed using polyetherimide. The first module 10 and the second module 20 may be manufactured by injection.

On the other hand, since the compression force received by the material gradually increases toward the lower portion of the juice drum 400 , deformation or damage of the first module 10 occurs or a gap formed between the first module 10 and the second module 20 . This may occur or deformation may occur. Accordingly, as can be seen in FIGS. 1A to 3B and 6A to 6B , an annular reinforcing ring 16 may be formed to fix the slit 12 of the first module 10 . The reinforcing ring 16 may be formed at the lower end or between the upper and lower ends of the first module 10 to hold the slit 12, and may be formed in the form of an annular flange at the lower opening. Accordingly, the slit 12 is not widened or the width thereof is not changed during the juicing process.

When the reinforcing ring 16 is formed at the lower end of the first module 10 , an annular protruding ring 15 protruding upward may be formed on the inner circumferential surface of the reinforcing ring 16 . In addition, a reinforcing ring residue outlet 17 communicating with the residue outlet 230 may be formed on one side of the reinforcing ring 16 .

In addition, as shown in FIGS. 5A to 6B , an annular flange 27 is formed at the lower end of the second module 20 to support the first module 10 .

Meanwhile, the first screw packing 330 may be coupled to the outer circumferential surface of the screw shaft 320 as shown in FIG. 7C . When the screw shaft 320 is inserted into the drum hole 260 , the first screw packing 330 seals the outer peripheral surface of the drum hole 260 . Accordingly, it is possible to prevent the juice from flowing into the drum hole 260 during the juice extraction process.

Furthermore, a packing groove 340 may be formed on the lower outer circumferential surface of the screw 300 , and a second screw packing (not shown) may be coupled to the packing groove 340 . When the packing groove 340 is seated on the seating part formed on the inner lower side of the second module 20, the second screw packing seals the inside of the seating part. Accordingly, it is possible to prevent the dregs from flowing into the juice outlet 220 during the juicing process.

As described above, according to the embodiment of the present invention, by configuring the juice drum 400 composed of two modules, it is possible to simplify cleaning and improve the juice extraction efficiency.

Meanwhile, it has been exemplified that the slit is formed in the first module 10 and the rib 22 is formed in the second module 20 . However, it will be understood from the description so far that even if a rib protruding radially outwardly is formed in the first module 10 and a slit into which the rib is inserted is formed in the second module 20 , the same function can be performed.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also provided. is within the scope of the right.
