Description

[0001] JUICE SQUEEZING DRUM AND JUICER [0002]

The present invention relates to a juice drum and a juicer used in a vertical low-speed juicer, and more particularly to a juice drum and a juicer composed of two modules.

In recent years, interest in health has increased in households, and the frequency of use of an electric juice dispenser having an ability to take juice from vegetables such as vegetables, grains, fruits, and the like is increased.

A typical operating mode of such a juicer is a method in which juice is pressed on a steel plate by using a principle of milling soybeans and squeezing the juice as disclosed in Korean Patent No. 793852, for example.

To this end, the juice dispenser includes a drum housing having a driving part for providing a rotational force, a driving shaft for receiving a rotational force from the driving part, a screw for pressing and crushing the juice object by a screw spiral formed on a part of the driving shaft, And a juice drum for separating juice produced by the juice. The driving unit that provides rotational force to the juicer includes a motor and a speed reducer. The motor is connected to the drive shaft so as to transmit rotational force to the screw. To this end, the drive shaft passes through the lower portion of the drum housing and is connected to the screw.

Generally, the juice drum has a mesh structure composed of mesh balls. In the case of a juice drum having a mesh structure, since the juice is easily clogged by the residue of the juice during the juicing process, the juice efficiency is low. In addition, since the mesh is formed closely, there is a problem that it is difficult to wash off the residue of the juice to be applied to the mesh. In addition, it is possible to assume various filter structures, but it is difficult to apply it to a juicer of a compression type using a screw such as performing a simple filtration function.

In addition, a minute round hole is formed on the side surface of the conventional mesh drum to discharge the juice produced in the mesh drum to the outside. However, if the debris trapped in the vents is not cleanly cleaned, the debris may be spoiled and the germs may propagate. In the conventional network drum structure, there is a problem that it is difficult to wash the debris trapped in the vents.

The juice drum according to one embodiment of the present invention is designed to solve the problems described above. The juice drum is composed of two modules and can be applied to a juicer of a pressing type, The present invention has been made to solve the above problems.

The juice drum according to an embodiment of the present invention is a juice drum for separating juice and debris from a juice to be juiced by a screw rotating in the inside of the juice drum. The juice drum is formed as a hollow cylinder whose top is opened to accommodate the screw, An inner module having a plurality of slits formed by through holes having upper and lower surfaces; And an outer module which is opened at an upper portion to be detachable from the upper side of the inner module and has a protruding surface and an upper surface and a lower surface protruding radially inwardly from the inner module, Wherein the ribs of the outer module are inserted into the slits of the inner module when the modules are coupled to surround the module so that the juice sucked by the screw is discharged between the slit side of the inner module and the rib side of the outer module, The gap may be formed to be long in the vertical direction, and the circumferential width of the gap formed between the slit and the rib may be wider toward the outer side in the radial direction.

The gap between both side surfaces of the slit may be formed to widen toward the radially outer side.

The width of the ribs may be widened toward the radially inner side.

Wherein a plurality of rib jaws protruding radially inward from the inner peripheral surface of the inner module are formed at regular intervals, the plurality of rib jaws have a relatively short length and a low projection height, and a relatively wide width A first rib jaw formed on the narrow bar; And a second rib jaw having a relatively long length and a high protruding height and formed on a relatively wide rod formed between the slits.

The outer circumferential surface of the inner module and the inner circumferential surface of the outer module may be closely attached to each other.

A juice outlet may be formed between the plurality of first seals formed in the outer module.

And a second joint protruding from an inner circumferential surface of the outer module.

The second cover may be in close contact with an outer circumferential surface of a rod formed between the slits of the inner module.

A juice drain hole may be formed in the outer module.

The outer module may include a lower cylinder and an upper cylinder having a larger diameter than the lower cylinder, and the juice discharge hole may be formed on a stepped surface formed between the upper cylinder and the lower cylinder.

According to another embodiment of the present invention, the juicer may include a drum housing having a coupling groove on which a protrusion formed on the outer peripheral surface of the outer module is seated.

A juice drum according to another embodiment of the present invention is a juice drum for separating juice and debris from a juice to be juiced by a rotating screw in the inside of the juice drum. The juice drum is formed as a hollow cylinder having an open upper portion for receiving the screw, An inner module having a plurality of slits formed in through holes having both side surfaces and upper and lower surfaces; And an outer module which is opened at an upper portion to be detachable from the upper side of the inner module and has a protruding surface and an upper surface and a lower surface protruding radially inwardly from the inner module, Wherein the ribs of the outer module are inserted into the slits of the inner module when the modules are coupled to surround the module so that the juice sucked by the screw is discharged between the slit side of the inner module and the rib side of the outer module, And the gap formed between the slit and the rib may be formed to be narrower in the lower side gap than in the upper side gap.

The width of the slit may be constant and the width of the rib may be narrower toward the upper side.

A stepped portion may be formed at a central portion of the rib, and a width of the lower side rib may be greater than a width of the upper side rib with respect to the stepped portion.

Also, at least one or more of the solutions set forth above may be applied to devise a juicer.

According to the embodiments of the present invention as described above and the juice drum to which the technical ideas common to these are applied, since the two juice drums can be combined with each other, the two modules can be easily assembled and disassembled, The drum is easy to manufacture and easy to clean.

The drive motor includes a speed reducer (not shown), and the speed reducer decelerates the rotation speed (about 1800 rpm) of the drive motor so that the screw 300 rotates at a low speed (about 80 rpm or less). This makes juice possible without destroying nutrients. Generally, a juicer having such an arrangement structure is referred to as a vertical low-speed juicer.

Figures 2a and 2b are exploded perspective views of the juicer according to one embodiment shown in Figures 1a and 1b of the present invention. In order to avoid redundant description, the body portion is omitted. As shown in FIGS. 2A and 2B, the hopper 100 is capable of feeding a juice (for example, vegetables, grains, fruit, etc.) into the hopper 100 and feeding the juice into the juice drum 400 Guide.

The object to be juiced is conveyed to the lower part by the first screw projections 310 and the object to be juiced is pressed by a narrow gap between the screw 300 and the juice drum 400. The spacing between adjacent first helical projections 310 formed on the top of the screw 300 may be greater than the spacing between neighboring first helical projections 310 formed below the screw 300. [

Figures 2c and 2d are exploded perspective views of the juicer according to another embodiment shown in Figures 1c and 1d of the present invention. The juicer according to another embodiment of the present invention is substantially the same as the embodiment of the juicer shown in Figs. 2A and 2B described above, but the shape of the juice drum 400 is different. The difference is that the juice drum 400 is seated on the upper portion of the main body 1 so that the driving shaft 6 of the driving motor 5 can transmit power to the screw 300 on the same axis, Do not. In the drawing, the first modified example of the first embodiment of the present invention will be described. However, the present invention is also applicable to FIGS. 1A and 1B.

The common structure of the juice drums of the present invention to accomplish the object of the present invention will be briefly described in advance of the detailed description of the embodiments of the individual juice drums.

FIGS. 3A and 3B are exploded perspective views of a juice drum according to a first embodiment of the present invention, and FIGS. 4A and 4B are perspective views of a juice drum according to a first embodiment of the present invention. Figs. 5A to 5D are modifications of the juice drum of the present invention, and Fig. 6 is an embodiment of the inner module of the juice drum of the present invention.

As can be seen in FIGS. 3A-6, the juice drum 400 is hollow cylindrical or frusto-conical in shape and can be squeezed or crushed by interaction with the screw 300.

The juice drum 400 of the present invention is composed of two modules in which a cylindrical inner module 10 and an outer module 20 are detachably assembled. When the two modules are combined, the juice sucked by the screw is caught A narrow gap is formed so as to come out.

The inner module 10 is formed in a hollow cylindrical shape having an open top so that the screw 300 can be received therein, and one or more slits 12 are formed on the inner surface of the inner module 10, If necessary, the lower part may also be formed into an open cylindrical shape. The slit 12 is formed as a through hole including both side surfaces and upper and lower surfaces so that the interval between the slits is fixed, and the side surface, the upper surface and the lower surface may be formed continuously without being bounded to each other.

The outer module 20 is formed in a cylindrical shape having an open upper part to be detachably coupled to the inner module 10 and includes a rib inserted into the slit 12 of the inner module 10 22 are formed. If necessary, the lower part may also be formed into an open cylindrical shape. The ribs 22 may be formed as side surfaces and protruding surfaces, and upper and lower surfaces may be formed continuously without being bounded to each other by comb teeth or protrusions including both side surfaces, protruding surfaces, upper surfaces and lower surfaces.

The rib 22 is formed in the inner module 10 such that when the inner module 10 and the outer module 20 are combined, a predetermined fixed gap is formed between the inner module 10 and the slit 12 of the inner module 10, Has a position and shape corresponding to the slit (12) and juice is filtered out between the gaps when juicing. More specifically, the ribs 22 are fixed between both side surfaces of the inner module slit 12 and both side surfaces of the ribs 22 of the outer module 20 when the inner module 10 and the outer module 20 are engaged. The inner module 10 has a position and a shape corresponding to the slit 12 of the inner module so that the minute gap formed is narrow and long. When the object is juiced by the interaction with the screw 300, juice is filtered between the gaps formed on the inner module 10 side And the residue is left inside the inner module 10.

The interval of the gaps may be determined according to the requirements of the design of the module and the specific design conditions of the various materials, and it is sufficient that the gaps are spaced such that the wastes can be filtered out during the pressing of the juice.

Further, since the gap can be drained if it is a through hole formed so as to cross the spiral of the screw 300 when the screw 300 is received in the juice drum 400, the shape of the slit 12 can be a rod- Or any shape thereof.

The upper module 20 is opened so that the inner module 10 can be freely attached and removed to the upper side of the outer module 20, The inner module 10 and the outer module 20 have a generally truncated conical shape that narrows downward as the rib 22 of the outer module 20 is inserted into the slit 12 of the module 10, Is formed to be smaller than the inner diameter of the outer module (20).

Accordingly, it is possible to easily separate two modules while improving the juicing efficiency compared to the conventional network drums, thereby facilitating the cleaning, and the problem of clogging of the net holes in the conventional network drum is fundamentally resolved and the brushes And various components for driving the brush are not necessary.

6 shows an inner module 10 of a juice drum according to an embodiment of the present invention. As shown in FIG. 6, ribs 13 and 14 protruding radially inward at regular intervals are formed on the inner circumferential surface of the inner module 10 of the present invention composed of two modules according to one embodiment of the present invention . The rib jaws 13 and 14 are formed along the vertical direction on the inner peripheral surface of the inner module 10. Since the outer module 20 does not directly interact with the screw 300, the rib jaws 13 and 14 that grind down and crush the juice object in cooperation with the screw 300, And is not formed on the inner surface of the outer module 20. As shown in FIG. 7B, in an embodiment of the present invention, the screw 300 is fully received in the inner module 10 so that the screw 300 entirely interacts with the inner module 10. The rib jaws 13 and 14 are formed over the entire upper and lower portions of the inner module 10 that interact with the screw.

The rib jaw can be divided into a long rib and a short rib, and can be divided into a first rib jaw having a relatively short height and a second rib jaw having a relatively long protrusion height. The compression force is increased more and more as the material is effectively moved from the upper portion to the lower portion of the inner module 10 by the screw and the second rib jaws 14. [ The juice generated by the compression of the compressive force is filtered through the gap formed by inserting the ribs 22 of the second module 20 into the slit 12 of the inner module 10 and is discharged to effect effective juicing. At this time, the material to be conveyed downward while being compressed is finely pulverized by the plurality of first rib jaws 13 formed on the lower side of the second rib jaw 14. At this time, the material is strongly pressed by the conveying compressive force applied to the material, and the juice is squeezed out and ejected into the gap to increase the juice efficiency.

The second rib jaws 14 protruding in the screw side radial direction may be additionally formed on the inner peripheral surface of the inner module 10 perpendicular to the longitudinal direction. In the absence of the second rib jaw 14, a material such as vegetables can not be smoothly conveyed downward along the screw helix when the screw rotates, and congestion may occur in the juice drum. When the second rib jaw 14 is formed, as the screw rotates, the material is smoothly conveyed downward along the screw spiral, crushed and crushed, and the second rib jaw 14 itself reinforces the rigidity of the inner module 10 .

The protrusion height of the second rib jaw 14 may be equal to the height from the upper portion to the lower portion, or may be gradually decreased from the lower portion. Since the slit 12 is not formed on the surface 10-1 where the second rib jaw 14 is formed on the outer peripheral surface of the inner module 10, the rigidity of the inner module 10 is reinforced.

Further, the second rib jaw 14 may be inclined downward from the upper portion to the lower portion, and a step portion 14-1 may be formed at an intermediate portion thereof so as to protrude toward the screw. The step portion 14-1 of the second rib jaw 14 can be variously modified in its position, number, or protruding height according to the shape of the screw and the design conditions of the spiral.

In addition, the second rib jaw 14 may be gradually lowered to the lower portion, and the second rib jaw 14 may not be formed in the lower portion of the inner module 10.

As shown in Figs. 3A and 3B and Figs. 5A and 5B, the outer module 20 is provided with ribs 22 (corresponding to the outer surface 10-1 of the inner module 10) To the function of fixing the coupling position while guiding the inner module 10 to the outer module 20 when the inner module 10 and the outer module 20 are coupled with each other by forming the guide surface 20-1 on which the inner module 10 is not formed So that the gap is fixed and can not be moved.

Further, the lower end of the inner module 10 may be completely opened, and an annular flange portion 16 which is open at the center and extends inward may be formed. When the lower end of the inner module 10 is completely opened, the debris is directly discharged downward. However, when the flange portion 16 is formed at the lower end of the inner module 10, the effect of juicing efficiency can be enhanced by stagnating the debris . In this case, a helical guide jaw 27-1 extending from the second rib jaw 14 toward the center of the inner module 10 is formed on the upper surface of the flange portion 16 so that the debris is caught and accurately guided downward .

The first rib jaw 13 protrudes in the radial direction of the screw and is formed perpendicularly to the inner circumferential surface of the inner module 10 along the longitudinal direction and protrudes in the form of a plurality of spaced apart from each other along the inner circumferential surface of the inner module 10 . The first rib jaw 13 performs a function of finely and uniformly secondarily grinding a material such as vegetables while being fed to the bottom while being juiced by the rotation of the screw. Therefore, the protrusion height of the first rib jaw 13 is generally lower than the protrusion height of the second rib jaw 14, and is shorter than the length of the second rib jaw 14.

The length of the first rib jaw 13 may be equal to or less than the length of the slit 12 of the inner module 10. The inner rib 10 may be formed to extend downward beyond the second rib jaw 14 as viewed from the upper end of the inner module 10 to the lower end of the inner module 10. [

Further, the first rib jaw 13 can further form a stepped portion in the middle thereof. The stepped portion can prevent the juice material from hanging and stagnating.

5b to 5d, the first rib jaw 13 may be formed close to the upstream edge of the slit 12 in the screw rotational direction. As the first rib jaw 13 is formed closer to the upstream edge of the slit 12 in the screw rotating direction, it functions as a speed limiter. As the material is compressed and conveyed, the pressing force of the gap is lowered, And the phenomenon that comes together with less.

Further, the inclined portion 18 can be formed by pulling the downstream side edge of the slit 12 of the inner module 10 in the screw rotating direction. When the inclined portion 18 is formed, the phenomenon that the debris that has passed through the first rib jaw 13 smoothly moves and joins to the downstream side gap is reduced.

The circumferential width of the gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 can be made wider toward the outer side in the radial direction. In other words, the gap on the downstream side is wider than the gap on the upstream side in the direction in which the juice is ejected, so that the flow of the juice to be extruded can be made smooth. In order to achieve this, both sides of the slit 12 of the inner module 10 may be widened toward the outside in the radial direction, and the width of the protruding surface of the rib 22 of the outer module 20 may be radially inward It may have a wider shape.

In addition, the width of the slit 12 and the width of the rib 22 are relatively matched so that the lower side gap of the juice drum, which is drained from the juice, can be narrower than the upper side gap. By doing so, it is possible to more easily remove the granules of the material which is reduced by the compressive force increasing toward the lower part, and the juice overflowed by the lower side debris can be discharged to the upper side gap, thereby improving the juicing efficiency. To this end, the gap of the slit 12 of the inner module 10 may be made wider toward the lower side, and the width of the rib 22 of the outer module 20 may be wider toward the lower side. It is also preferable that a step 121 is formed in the slit 12 of the inner module 10 and the upper slit width is smaller than the lower slit pot with respect to the step 121, The width of the lower side rib 22 may be formed wider than the width of the upper side with respect to the stepped portion 24 by forming the step portion 24 on the rib 22 of the lower side rib 20.

7B to 7D, the outer diameter of the inner module 10 and the inner diameter of the outer module 20 are relatively matched to each other, so that the space between the outer surface of the inner module 10 and the inner surface of the outer module 20, It can be gradually widened toward the side. The juice discharged through the gap formed between the slit 12 and the rib 22 widens toward the lower side and the juice can be smoothly discharged to the juice discharge port 220. [

Hereinafter, various embodiments and some configurations not described above will be described in more detail with the common structure of the juice drums 400 according to the embodiments of the present invention. As described above, the juice drum according to embodiments of the present invention includes an inner module 10 and an outer module 20, and the inner module 10 and the outer module 20 are detachably coupled to each other .

The inner module 10 has a hollow cylindrical shape opened upside down and includes at least one elongated slit 12. The slit 12 is formed downward at a position spaced apart from the lower portion of the upper end of the inner module 10 by a predetermined distance. The outer module 20 has a hollow cylindrical shape and includes at least one rib 22 inserted corresponding to the slit 12 formed in the inner module 10. A predetermined gap is formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 when the outer module 20 and the inner module 10 are combined, The juice separated from the generated debris 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 of the conventional mesh structure.

Depending on the type of juicer to which the juice drum is applied, the juice drum may have various forms as shown in Figures 3a to 9b. For example, the inner module 10 and the outer module 20 may have the same length or the outer module 20 may have a length shorter than the inner module 10.

The slit 12 may be formed to correspond to the entire length of the inner module 10 (the length of the slit 12 is longer than the set distance), and the slit 12 may be formed only in the lower portion of the inner module 10 The length of the slit 12 is formed to be shorter than the set distance).

Further, the slit 12 may be divided into an upper slit formed on the upper portion of the inner module 10 and a lower slit formed on the lower portion of the inner module 10. The upper slit (12) is located further radially outward than the lower slit (12). In the present invention, the slits are not formed in the outer module 20, and the through holes formed in the outer module 20 do not serve as slits but serve as passages for discharging the juice.

Meanwhile, the slit 12 is not limited to a rectangular hole or an elliptical hole, as long as the hole 300 is seen to cross the spiral of the screw 300 when the screw 300 is received in the juice drum. Further, the rib 22 is not limited to any shape as long as it can be inserted corresponding to the slit 12 to form a gap with the slit 12. In the cylindrical module, a hole portion in which the slit 12 is formed along the circumferential direction and a plate portion in which the slit 12 is not formed are alternately formed, and the slit 12 is not formed The plate portion 11 will be referred to as "rod ".

The rib 22 according to the embodiments of the present invention is inserted into the slit 12 of the inner module 10 and inserted into the rib 22 and the slit 12 in the radial direction, Any desired shape can be used so that the gap between the first screw projection 310 and the first screw projection 310 can be crossed.

Meanwhile, at least one rib jaw (13, 14) may be formed apart from the inner peripheral surface of the inner module (10). The rib jaws 13 and 14 may be formed in the longitudinal direction of the inner module 10. The ribs 13 and 14 formed on the inner circumferential surface of the inner module 10 and the ribs 22 of the outer module 20 inserted into the slit 12 of the inner module 10 are inserted through the above- ) Will perform different functions.

If there is no such rib jaws 13 and 14, the juice object may not go down and become stagnant, or the pressing force or the crushing force may be low or not generated. Since the inner module 10 can be deformed by the compressive force generated when the material is transferred and compressed by the spiral 310 of the screw 300, the rib jaws 13, 14 may be formed. In addition, one rib jaw 13, 14 can be formed in one flesh.

The rib jaws 13 and 14 are formed on the inner peripheral surface of the rod 11 on which the slit 12 of the inner module 10 is not formed and the ribs 13 and 14 have a length shorter than or equal to the length of the slit 12, The slit 12 is formed to be vertically or vertically closer to the inner circumferential surface of the rod 13 without the slit 12 formed therein than the jaw 13 (hereinafter referred to as "first rib jaw") and longer than the length of the slit 12 And a rib jaw 14 (hereinafter referred to as "second rib jaw").

Generally, the rib jaws 13 and 14 serve to allow the material to be introduced into the juice drum 400 to fall down in a narrow portion abutting the screw 300. The rib jaws 13 and 14 can function to squeeze and squeeze the material together with the screw 300 while lowering the material down. Therefore, the rib jaws 13 and 14 do not necessarily have to be formed in the longitudinal direction of the juice drum 400 but are formed so as to intersect the spiral 310 of the screw 300. In order to efficiently convey and press the material, But may also be implemented in a sloped form with a constant slope.

Meanwhile, the second rib jaw 14 is formed on the inner circumferential surface of the rod 11 along the longitudinal direction. The second rib jaw 14 is formed in the process of conveying and pressing the material by the spiral of the screw 300, A function of adjusting the receiving position of the screw 300 in the juice drum 400 and adjusting the juice space can be performed.

In addition, the protrusion height of the second rib jaw 14 may be configured to have the same height from the upper portion to the lower portion. However, as shown in FIGS. 3A, 6, and 8B, At least one step portion 14-1 may be formed at an intermediate portion of the two ribs 14 in the longitudinal direction.

3A to 9B, the plurality of rods 11 may include a rod 11 having a relatively narrow width and a rod 11 having a relatively wide width. The first ribs 13 are formed on the inner circumferential surface of the rod 11 having a relatively narrow width and the second ribs 14 can be formed on the inner circumferential surface of the rod 11 having a relatively wide width.

Further, instead of forming the rib 22 on the inner peripheral surface of the outer module 20 abutting the outer peripheral surface of the relatively large rod 11 of the inner module 10 when the inner module 10 and the outer module 20 are coupled, Means for securing the inner module 10 and the outer module 20 may be provided.

5B, a key projection 25 may be formed on a part of the inner peripheral surface of the outer module 20, and a key groove 15 may be formed on an outer peripheral surface of the inner module 10, The engagement position of the inner module 10 and the outer module 20 can be fixed by inserting the protrusion 25 into the key groove 15. [ The engagement of the inner and outer modules 10 and 20 with respect to each other can be restricted by fitting the key projection 25 into the key groove 15.

Separately, as can be seen in FIG. 5A, the engaging projection 19 can be formed at the lower end of the outer periphery of the relatively wide rod 11 of the inner module 10, and the relatively wide rod 11 An engaging groove 29 can be formed in the lower end annular flange 27 of the outer module 20 facing the engaging projection 19. By the engagement of the engaging groove 29 and the engaging projection 19, the relative position of the outer module 20 with respect to the inner module 10 is determined, so that the size of the gap can be maintained.

In the above-described embodiment, the protrusions may be grooves, the grooves may be deformed into protrusions, and the means for fixing the inner module 10 and the outer module 20 are not limited to the above-described coupling grooves and coupling protrusions.

The inner module 10 and the outer module 20 may be separated from each other by a space formed between the inner circumferential surface of the outer module 20 where the ribs 22 are not formed and the outer circumferential surface of the inner module 10 corresponding thereto, There is a space for the juice to flow between and the juice flows down without interruption.

In another aspect, the spacing space between the inner circumferential surface of the outer module 20 where the ribs 22 are not formed and the outer circumferential surface of the inner module 10 corresponding thereto is formed to be lower It can grow bigger.

In another aspect, in order to form a spacing space between the inner circumferential surface of the outer module 20 where the ribs 22 are not formed and the outer circumferential surface of the corresponding inner module 10, Or at least one stepped portion whose outer diameter is reduced at the longitudinal center position of the outer peripheral surface of the inner module 10 may be provided.

3a to 9b, the width of the rod 11 formed between the slits 12 of the inner module 10 (the distance between one slit and the adjacent slit along the circumferential direction) It is possible to have a shape widening toward the center. In this case, the gap formed between the slit 12 of the inner module 10 of the juice drum 400 and the rib 22 of the outer module 20 becomes wider as it goes outward from the inner side in the radial direction, It is possible to prevent the above-mentioned gap from being clogged or disturbing the flow of the juice due to the scum.

In one aspect, the rod 11 formed in the inner module 10 may have a generally semicircular, elliptical, or trapezoidal cross-section in order to increase the width of the rod 11 toward the radial center.

On the other hand, the material is conveyed downward by the rotation of the screw 300 inside the inner module 10 of the juice drum 400, and the interval between the screw 300 and the inner peripheral surface of the inner module 10 gradually increases As the material becomes narrower, the material gradually compresses and the granules become smaller, and the compressive force due to the compression of the material becomes larger and larger as it goes downward. Therefore, the lower side gap of the juice drum from which the juice is filtered out can be formed narrower than the upper side gap. Depending on the material, the drainage of the juice through the lower side gap may be impeded by the scum generated during the juicing process. Therefore, the upper side gap of the juice drum can be formed relatively wider than the lower side gap so that the juice overflows through the upper side gap. That is, the gap formed between the slit 12 of the inner module 10 of the juice drum and the rib 22 of the outer module 20 can be configured such that the lower portion is continuously or discontinuously narrower than the upper portion.

3A and 9B, the width of the slit 12 of the inner module 10 can be made wider toward the lower side and the width of the slit 12 of the inner module 10 can be increased, May be formed to be narrower toward the upper side. In another aspect, the width of the slit 12 of the inner module 10 may be made constant and the width of the rib 22 of the outer module 20 may be made narrower toward the upper side.

3A to 9B, a step is provided at the longitudinal center portion of the inner module 10 or the outer module 20, and the slit 12 (see Fig. 3A) of the inner module 10 Of the outer module 20 and the rib 22 of the outer module 20 can be wider than that of the lower side so that the width of the rib 22 of the outer module 20 is set at the upper side It can be made narrower.

On the other hand, the juice drum 400 can be made of a high strength material which is harmless to the human body and is strong enough to withstand the pressure generated during the juicing process and to maintain the gap between the slits 12. Also, the juice drum 400 may be made of a single thin plate made of high strength material.

In one aspect, the inner module 10 and the outer module 20 may be made integral using a polyetherimide. The inner module 10 and the outer module 20 can be manufactured by injection molding.

As the compressing force of the material gradually increases toward the lower part of the juice drum 400, deformation or breakage of the inner module 10 occurs or a gap formed between the inner module 10 and the outer module 20 is opened Deformation may occur. Therefore, as shown in FIGS. 3A and 9B, an annular reinforcing ring or flange 16 can be formed to fix the slit 12 of the inner module 10. The reinforcing ring 16 may be formed between the lower end or the upper end and the lower end of the inner module 10 to hold the slit 12 and may be formed in the shape of an annular flange at the lower end opening. As a result, the slit 12 is not opened or the width of the slit 12 is not changed during the juicing process, and the screw can be seated in the juice drum. 5A to 5C, an annular flange 27 may be formed at the lower end of the outer module 20 to support the inner module 10. As shown in FIGS.

Figures 3a-b are views of various embodiments of a juice drum of the present invention. The first embodiment of the juice drum of the present invention can be applied to all of the juicers shown in Figs. 1A to 1B.

3A and 3B are exploded perspective views of a juice drum according to a first embodiment of the present invention. The first embodiment of the juice drum shown in Figs. 3A and 3B can be applied to the juicer shown in Figs. 1A to 1B. As shown in FIGS. 3A and 3B, the juice drum 400 may include an inner module 10 and an outer module 20. Basically, the juice drum 400 of the present invention is composed of two modules in which a cylindrical inner module 10 and an outer module 20 are detachably assembled, and when the two modules are combined, A narrow gap is formed so as to protrude.

The inner module 10 and the outer module 20 can be made integral by using polyetherimide (PEI). The inner module 10 and the outer module 20 can be manufactured by injection molding.

The inner module 10 is generally cylindrical in shape, and the upper and lower sides thereof can be opened. The inner module 10 includes a plurality of rods 11 and a plurality of slits 12 are formed by the plurality of rods 11.

The outer module 20 is formed in a cylindrical shape with an open upper part to be detachably coupled to the inner module 10 and includes a rib inserted into the slit 12 of the inner module 10 when coupled with the inner module 10 22 are formed. If necessary, the lower part may also be formed into an open cylindrical shape. The ribs 22 are rib-shaped protrusions including both side surfaces, protruding surfaces, upper and lower surfaces, and the side surfaces and the protruding surface, and the upper surface and the lower surface may be formed continuously without being bounded to each other.

The rib 22 is formed in the inner module 10 such that when the inner module 10 and the outer module 20 are combined, a predetermined fixed gap is formed between the inner module 10 and the slit 12 of the inner module 10, Has a position and shape corresponding to the slit (12) and juice is filtered out between the gaps when juicing.

The interval of the gaps may be determined according to the requirements of the design of the module and the specific design conditions of the various materials, and it is sufficient that the gaps are spaced such that the wastes can be filtered out during the pressing of the juice. Further, since the gap can be juiced if it is a through-hole name formed so as to intersect the spiral of the screw 300 when the screw 300 is received in the juice drum 400, the shape of the slit 12 can be either a rod- Or any shape thereof.

The upper module 20 is opened so that the inner module 10 can be freely attached and removed to the upper side of the outer module 20, The inner module 10 and the outer module 20 have a generally truncated conical shape that narrows downward as the rib 22 of the outer module 20 is inserted into the slit 12 of the module 10, Is formed to be smaller than the inner diameter of the second module (20).

In addition, since the pressure is more applied to the lower side of the juice drum 400 during the pressing process, it is preferable to make the lower side gap of the juice drum 400 narrower. Therefore, the upper side width of the slit 12 may be narrower than the lower side width of the slit 12 as shown in FIG. 3A. That is, the width of the slit 12 may become narrower toward the upper side. The slits 12 may be formed with stepped portions 121. The upper side width of the slit 12 may be smaller than the lower side width of the slit 12 with respect to the step portion 121. [

3A and 6, the width of the rib 22 on the upper side may be smaller than the width of the rib 22 on the lower side. That is, the width of the ribs 22 may become narrower toward the upper side. Further, the ribs 22 may be formed with the stepped portions 24. The width of the upper side rib 22 may be smaller than the width of the lower side rib 22 with respect to the step portion 24. Furthermore, the width of the rib 22 on the upper side of the stepped portion 24 may become narrower toward the upper side.

On the other hand, ribs protruding in the vertical direction can be formed on the inner circumferential surface of the inner module 10 of the present invention composed of two modules at regular intervals.

The rib jaw can be divided into a long rib and a short rib, and can be divided into a first rib jaw having a relatively short height and a second rib jaw having a relatively long protrusion height.

The compressive force is increased more and more as the material is effectively moved from the upper portion to the lower portion of the inner module 10 by the screw and the second rib jaws 14. [ The juice generated by the compression of the compressive force is filtered through the gap formed by inserting the ribs 22 of the second module 20 into the slit 12 of the inner module 10 and is discharged to effect effective juicing. At this time, the material to be conveyed downward while being compressed is finely pulverized by the plurality of first rib jaws 13 formed on the lower side of the second rib jaw 14. At this time, the material is strongly pressed by the conveying compressive force applied to the material, and the juice is squeezed out and ejected into the gap to increase the juice efficiency.

That is, when the screw 300 is housed in the inner module 10 and rotates while grinding the juice, the debris generated is caught between the outer surface of the screw 300 and the inner circumferential surface of the inner module 10. At this time, the debris that rotates due to the rotational force of the screw 300 may bump against the rib jaws 13 and 14 and may descend downward of the inner module 10.

The second rib jaw 14 may function to reinforce the rigidity of the inner module 10 and may guide the juice extractor 400 to the lower part of the juice extractor drum 400. The inner module 10 has a thin overall thickness and can be made less rigid by the slit 12. Therefore, the rigidity of the inner module 10 can be reinforced by forming the second rib jaws 14 in the inner module 10. The function of guiding the juice to the lower portion of the juice drum 400 by the second rib jaw 14 is as described above. The second rib jaw 14 may function to fix the receiving position of the screw 300 in the juice drum 400 and fix the juice space.

The first and second rib jaws 13 and 14 function to squeeze and squeeze the material together with the screw 300 while moving the juice object and the residue downward. Therefore, the first and second rib jaws 13 and 14 do not necessarily have to be formed in the lengthwise direction of the juice drum 400 but are formed to cross the spiral 310 of the screw 300, But may also be implemented in an inclined form having a constant slope with respect to the longitudinal direction.

On the other hand, the plurality of rods 11 may include a rod 11 having a relatively narrow width and a rod 11 having a relatively wide width. In embodiments of the present invention, a plurality of bars (e.g., three bars) of relatively narrow widths are disposed at regular intervals and a plurality of bars of relatively narrow widths A wide rod can be placed. At this time, the first rib jaws 13 are formed on the inner circumferential surface of the relatively small rod 11, and the second rib jaws 14 can be formed on the inner circumferential surface of the rod 11 having a relatively wide width.

As shown in FIGS. 3A and 3B, in order to fix the coupling position of the inner module 10 and the outer module 20, a gap between the plurality of ribs 22 is relatively narrow and a space relatively large . The bar 11 having a relatively large width may be located in a space where the interval between the plurality of ribs 22 is relatively large. The key projection 25 may be formed in a space having a relatively large gap between the plurality of ribs 22.

4A and 4B are perspective views of a juice drum according to a first embodiment of the present invention.

As shown in FIG. 4A, the width of the rod 11 (the distance between one first slit and the adjacent first slit along the circumferential direction) widens toward the radially inner side of the inner module 10 . For this purpose, the rod 11 may have a semicircular, elliptical, or trapezoidal cross section.

Referring again to FIG. 3A, a key groove 15 may be formed on the outer peripheral surface of the inner module 10. For example, the key groove 15 may be formed in a substantially triangular shape with respect to the vertical cross section of the inner module 10. The key groove 15 may be formed on the outer peripheral surface of the rod 11 having a relatively large width.

A key projection 25 may be formed on the inner peripheral surface of the outer module 20. The key projection 25 may be formed in a shape corresponding to the key groove 15 of the inner module 10. That is, the key protrusion 25 may be formed in a substantially triangular shape with respect to the vertical section of the outer module 20 so that the protrusion 25 protrudes from the upper surface of the outer module 20 and protrudes downward.

The inner protrusion 25 of the outer module 20 is inserted into the key groove 15 of the inner module 10 when the inner module 10 is coupled to the outer module 20, The coupling position of the outer module 20 can be fixed. The key projection (25) is fitted in the key groove (15), so that the coupling position, relative rotation, and tilting of the inner module (10) and the outer module (20) can be restricted.

Also, an annular first flange 16 may be formed on the underside of the rod 11. The first flange 16 supports the width of the slit 12 between the plurality of rods 11 to be fixed. As the comb teeth rod 11 is fixed by the first flange 16, the slits 12 are formed with through holes fixed to the upper and lower surfaces and both side surfaces.

The rod 11 is formed as a cantilever extending in the vertical direction, and the pressing force between the screw 300 and the inner module 10 becomes larger toward the lower side. Therefore, there is a fear that the lower portion of the rod 11 is deformed by the pressing force between the screw 300 and the inner module 10. [ In order to prevent such a problem from occurring, it is possible to prevent the width of the slit 12 from being changed by the pressing force in the juicing process by supporting the lower portion of each rod 11 through the first flange 16 have.

On the other hand, as shown in FIG. 3B, a seating part 17 supported by the bottom surface of the drum housing 200 is formed in the lower part of the inner module 10. The seating part 17 may be formed as a groove protruding downward from the first flange 16 or extending upward from the first flange 16.

3A, the outer module 20 is configured such that the inner diameter of each portion of the outer module 20 is larger than the outer diameter of the corresponding portion of the inner module 10 so that the inner module 10 can be surrounded and engaged. Can be largely formed. The outer module 20 is generally cylindrical in shape, and the upper and lower sides thereof can be opened. The outer module 20 may include a plurality of first bracings 21 (referred to as first bracing to clearly distinguish it from another second bracing rod or a basic bracing rod). On the inner circumferential surface of the first cover 21, a rib 22 may be formed protruding radially inward.

A plurality of juice outlets (23) are formed by the plurality of first covers (21). The ribs 22 can be inserted into the slits 12 between the rods 11. A predetermined gap may be formed between the slit 12 and the rib 22 by inserting the rib 22 into the slit 12. The ribs 22 may be inserted into the slits 12 of the inner module 10 to form gaps therebetween that intersect the first spiral protrusions 310 Any shape is not limited thereto. The juice is discharged radially outward of the juice drum 400 through the gap and the juice separated debris can be collected in the inner lower part of the juice drum 400.

The material is conveyed downward by the rotation of the screw 300 inside the inner module 10 of the juice drum 400 and the interval between the screw 300 and the inner peripheral surface of the inner module 10 becomes narrower The material is gradually compressed so that the grain of the juice object becomes smaller, and the compressive force of the material becomes larger as it goes downward. Therefore, the lower side gap of the juice drum 400 from which the juice is filtered out can be narrower than the upper side gap. Depending on the material, the drainage of the juice through the lower side gap may be impeded by the scum generated during the juicing process. Therefore, the upper side gap of the juice drum can be formed relatively wider than the lower side gap so that the juice overflows through the upper side gap. For example, when the width of the slit 12 between the rods 11 is constant and the width of the rib 22 on the upper side of the stepped portion 24 becomes narrower toward the upper side of the stepped portion 24, The size of the gap widens 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 narrow gap formed mostly in the lower part during the pressing process. However, in the case of a juicy object such as tomato, in the process of squeezing, not only the juice formed in the lower side but also the juice object lodged in the lower side rises to the upper wide gap and the juice can be discharged through the upper gap have. When the size of the gap is not constant along the longitudinal direction (or up and down direction), juice efficiency can be improved for both a hard juice such as a carrot and a juicy juice such as a tomato.

The size of the gap can be kept constant without changing during the juicing process. In addition, in the case of a juicy object such as a carrot, it can be accumulated in the gap in a juicing process. In this case, as shown in FIG. 3A, 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.

7B to 7D, a space may be formed between the outer circumferential surface of the inner module 10 and the inner circumferential surface of the outer module 20, as shown in FIGS. The spacing space may become wider as it goes to the lower side of the juice drum 400. By forming the spacing space, a space can be secured in which the juice can be discharged and flowed through the gap between the slit 12 and the rib 22. Preferably, the inner module 10 is formed in a cylindrical shape with its diameter becoming smaller downward, so that the spacing space can be wider as it goes to the lower side of the juice drum 400. Alternatively, a step is formed at a lower side of the rod 11 of the inner module 10 so that the spacing becomes wider as it goes to the lower side of the juice drum 400 by the step.

4A, a space is not formed between the outer circumferential surface of the inner module 10 and the inner circumferential surface of the outer module 20, but the outer circumferential surface of the inner module 10 and the outer module 20 Can be closely attached to the inner circumferential surface. The inner module 10 and the outer module 20 are in close contact with each other even if the outer peripheral surface of the inner module 10 and the inner peripheral surface of the outer module 20 are in close contact with each other even if the juice drum 400 is vibrated during the juicing process, It can be effective that the size of the gap between the rib 13 and the rib 22 is kept constant.

Also, as shown in FIG. 3A, a protrusion 26 may be formed on the outer peripheral surface of the outer module 20. The protrusion 26 may be seated in the coupling groove 210 formed in the inner circumferential surface of the drum housing 200 shown in FIG. 2A. The outer circumferential surface of the juice drum 400 can be separated from the inner circumferential surface of the drum housing 200 by the protrusion 26 being seated in the engaging groove 210 and the state where the juice drum 400 and the drum housing 200 are separated from each other, Can be improved. Preferably, the protrusions 26 are formed at equal intervals in the circumferential direction at the upper end of the second module 20, and the coupling grooves 210 are formed at corresponding positions in the drum housing 200 So that when the juice drum 400 is coupled to the drum housing 200, it is easy to identify with the naked eye and can be easily assembled.

On the other hand, as shown in FIGS. 3A and 4A, an annular second flange 27 may be formed below the first cover 21. The first cover 21 may extend downwardly of the second flange 27. When the inner module 10 and the outer module 20 are assembled, the rod 11 formed on the inner module 10 may be formed to extend to the lower side of the second flange 27. In other words, when the inner module 10 and the outer module 20 are assembled, the entire area of the slit 12 formed in the inner module 10, regardless of the position of the second flange 27, A predetermined gap may be formed between the slit 12 and the rib 22 by inserting the rib 22 formed on the inner surface of the rib 21.

4A, the first flange portion 16 may extend radially inwardly from the inner circumferential surface of the inner module 10, and the upper surface of the first flange portion 16 may have a guiding jaw (27-1) may be provided. The guide protrusion 27-1 may extend from the second rib jaw 14 formed on the inner circumferential surface of the inner module 10 and may be inclined in the direction of rotation of the screw 300. [

The residue of the juice to be squeezed between the screw 300 and the inner module 10 is moved downward by the first rib jaw 13 and the second rib jaw 14. The debris is discharged from the waste outlet 230, The guiding jaw 27-1 formed of the slanting projections guides the waste to the waste outlet.

Figs. 5A to 5D show a first modification of the juice drum shown in Figs. 3A to 4B. This first modified embodiment of the juice drum can be applied to an exploded perspective view of the juicer of Figs. 2c and 2d.

5A to 5D, a first flange 16 for connecting the lower portion of the rod 11 of the inner module 10 is formed, and a coupling protrusion 19 is protruded from the first flange 16 do. The engaging projection 19 may be formed in a substantially rectangular shape and the engaging projection 19 may be formed to extend from the relatively wide rod 11. [ The engaging projections 19 may be spaced a predetermined distance in the circumferential direction so that a plurality of (for example, four) engaging projections 19 may be formed.

A second flange 27 is formed at the lower end of the outer module 20. The second flange 27 may be formed with an extension extending radially inwardly of the outer module 20. The extending portion is formed with an engaging groove 29 having a shape corresponding to the engaging projection so that the engaging projection 19 of the inner module 10 is inserted.

When the inner module 10 is inserted into and joined to the outer module 20, the engaging projections 19 are inserted into the engaging grooves 29, so that the inner module 10 and the outer module 20 can be accurately have.

In addition, the engaging projection 19 may take the role of the seat 17 shown in Fig. 3B. When the engaging projection 19 is used as the seating portion, the engaging projection 19 can fix the inner module 10 coupled with the outer module 20 to the bottom surface of the drum housing 200. Accordingly, the inner module 10 to which the outer module 20 is coupled can be seated and fixed to the drum housing 200.

The juice drums 400 shown in Figs. 5A to 5D may also have the key grooves 15 and the key projection 25 shown in Figs. 3A and 3B.

That is, when the inner module 10 and the outer module 20 are coupled to each other, the relative positions of the inner module 10 and the outer module 20 are first determined while the coupling protrusions are inserted into the coupling grooves, Since the relative positions of the inner module 10 and the outer module 20 can be determined secondarily as the protrusions 25 are fitted in the key groove 15, the relative positions of the inner module 10 and the outer module 20 The position is fixed.

The inner module 10 and the outer module 20 are coupled to each other by a coupling protrusion 19 and a coupling groove 29 at the lower part of the inner module 10 and the outer module 20, The relative rotation between the inner module 10 and the outer module 20 is restricted and the inner module 10 and the outer module 20 can be prevented from tilting with respect to each other .

Although the coupling protrusion 19 is formed in the inner module 10 and the coupling groove 29 is formed in the outer module 20 in the embodiment of the present invention, The coupling projections 19 may be formed in the outer module 20 and the coupling grooves 29 may be formed in the inner module 10. [ Although the key groove 15 is formed in the inner module 10 and the key projection 25 is formed in the outer module 20, the key groove 15 is formed in the outer module 20 The key projection 25 may be formed in the inner module 10.

Also, as shown in FIG. 5B, a protrusion 26 may be formed on the outer circumferential surface of the upper module 20. The projecting portion 26 may be seated in the coupling groove 210 formed in the inner circumferential surface of the drum housing 200 shown in FIG. The outer circumferential surface of the juice drum 400 can be separated from the inner circumferential surface of the drum housing 200 by the protrusion 26 being seated in the engaging groove 210 and the state where the juice drum 400 and the drum housing 200 are separated from each other, Can be improved. Preferably, the protrusions 26 are formed at equal intervals in the circumferential direction at the upper end of the second module 20, and the coupling grooves 210 are formed at corresponding positions in the drum housing 200 So that when the juice drum 400 is coupled to the drum housing 200, it is easy to identify with the naked eye and can be easily assembled.

5B and 6, a first rib protrusion 13 protrudes from the inner circumferential surface of the inner module 10, and the first rib protrusion 13 may be formed adjacent to the slit 12. Preferably, the first rib jaw 13 may extend radially inwardly from an edge of the slit 12 formed in the vertical direction. At this time, the height of the first rib jaw 13 may be longer than the width (or width) of the slit 12. An inclined portion 18 may be formed at the edge of the slit 12 facing the edge of the slit 12 where the first rib jaw 13 is formed.

Reference is made to Fig. 5D for the description of the inclined portion 18. Fig. 5D is a cross-sectional view of the portion "A-A" shown in Fig. 5C. 5D shows the juice drum viewed from below.

The position of the first rib jaw 13 and the inclined portion 18 will be described in detail with reference to FIG. 5D. The slit portion 18, which is provided in the inner module 10, The first rib jaw 13 is formed at an edge of the screw 12 and an inclined portion 18 is formed at an edge of the slit 12 following the rotation direction of the screw 300.

For example, when the screw 300 rotates counterclockwise inside the inner module 10, the first rib jaw 13 is formed to extend radially inward at the left edge of the slit 12, The portion 18 may be formed at the right edge of the slit 12.

A rib 22 of the outer module 20 is inserted into the slit 12 and a predetermined gap is formed between the slit 12 and the rib 22 to discharge the juice to be squeezed. At this time, the residue of the juice can be caught in the gap between the slit 12 and the rib 22.

It is possible to prevent the debris of the object to be juiced from being caught in the gap between the slit 12 and the rib 22 by the first rib jaw 13 and the inclined portion 18 formed on the slit 12. [

More specifically, when the screw 300 rotates inside the inner module 10, the debris of the juice to be crushed between the screw 300 and the inner module 10 rides on the first rib jaw 13 The residue moves to the lower side of the inner module 10 along the first rib jaw 13. In this case,

When the amount of the residue increases to exceed the first rib jaw 13, the residue rides over the first rib jaw 13 and is moved to the adjacent first rib jaw 13 by the rotational force of the screw 300 do. The debris moves by the height of the first rib jaw 13 to the adjacent first rib jaw 13 across the gap between the slit 12 and the rib 22 of the outer module 20. [ When the debris rides over the first rib jaw 13, the debris moves to the adjacent first rib jaw 13 along the inclined portion formed at the edge of the slit 12 facing the first rib jaw 13, The debris is prevented from being caught in the gap between the slit 12 and the rib 22 of the outer module 20. The debris striking the adjacent first rib jaws 13 moves to the lower side of the inner module 10 along the adjacent first rib jaws 13. In addition, the pressing force applied to the gap formed between the slit (12) and the rib (22) in the process of passing the juice object over the first rib jaw (13) is reduced, so that it is possible to minimize the accumulation of debris in the gap.

Referring to FIG. 6, the first rib jaw 13 formed on the inner circumferential surface of the rod 11, such as the juice drum shown in FIGS. 5A to 5D, may be formed adjacent to the slit 12. When the first rib jaw 13 is formed adjacent to the slit 12, the first rib jaw 13 functions like a speed braking jaw like the juice drum 400 shown in Figs. 5A to 5D, The debris is less likely to be caught in the gap than when the rib jaw 13 is formed in the central portion of the rod 11. [ The details of this are the same as those described above, so the description is omitted.

Figs. 7A to 7C are partial cross-sectional views of the juice drum of the first modified embodiment of the first embodiment combined with the drum housing. Fig. FIG. 7A is a top view of the juicer to which the juice drum of the first modified embodiment is applied, FIG. 7B is a sectional view in the "A-A" direction in FIG. 7A, and FIG. 7C is a sectional view in the "B- In this case, the cross-sectional view in the direction of "AA" is such that a section on the side of the juice outlet port 220 is visible, and the cross-sectional view in the direction of BB "is such that the cross section on the side of the debris outlet port 230 is visible. , The juice discharge passage and the debris discharge passage are shown clearly.

Referring to FIG. 7B, the juice outlet 23 formed in the outer module 20 is well illustrated. When the material is loaded on the upper portion of the hopper 100, the screw 300 is rotated to compress the material while being conveyed downward. In this process, the slit 12 of the inner module 10 and the rib 22 of the outer module 20 The juice is discharged through the gap.

The juice discharged from the gap moves downward between the inner circumferential surface of the drum housing 200 and the outer circumferential surface of the outer module 20 through the juice outlet 23 of the outer module 20 and is formed on the bottom of the drum housing 200 And flows through the juice discharge groove 297. And the juice is discharged through the juice discharge port 220 communicating with the juice discharge groove 297 (see the arrow in FIG. 7B).

Referring to FIG. 7C, there is shown a passage through which the debris pushed down by the gap between the inner module 10 and the screw 300 is discharged. The debris squeezed between the screw 200 and the inner module 10 flows through the debris discharge groove 298 and is discharged through the debris discharge port 230 communicating with the debris discharge groove 298 ).

At this time, the debris can not be directly transferred to the lower side of the inner module 10 by the second flange 27 extending radially inward at the lower end of the inner module 10, and the debris is temporarily transferred to the second flange 27 And remains on the upper surface. That is, the time during which the juice object stays between the screw 200 and the inner module 10 is increased, so that the juice can be sufficiently juiced and the juice efficiency is increased.

In this embodiment, the debris discharge can be controlled by the debris discharger 238 with the packing.

As can be seen from this drawing, the distance between the outer diameter of the inner module 10 and the inner diameter of the outer module 20 is further increased toward the lower side so that the juice drum 400 is formed wider toward the lower side.

7B, a drum hole 260 is formed at the center of the inner bottom surface of the drum housing 200 and may include a packing 261 for waterproofing the inner circumferential surface of the drum hole 260, And may include a cylinder protruding and inserted into the inner central space of the screw 300. A guide pin 290 is formed around the drum hole 260 so that the lower ring 390 of the screw 300 can be seated. The guide jaw 290 is formed at a predetermined height on the bottom surface of the drum housing 200 so as to be inserted into the inner circumferential surface of the lower ring 390 of the screw 300. In this way, while the screw is rotatably fixed and supported, the pressure of the debris or the juice is reduced so that the debris or juice does not enter the drive shaft.

An annular step 299 is formed on the inner bottom surface of the drum housing 200 so that the bottom flange side of the inner module 10 to which the outer module 20 is coupled can be abutted and engaged so that the residue does not flow into the juice discharge passage. .

Figs. 8A and 8B show another modified embodiment of the juice drum shown in Fig. 3A or Fig. 5A.

8A and 8B, the outer module 10 may further include a plurality of second seals 130 (the second seals may be clearly distinguished from another third comb rod or a basic comb rod) The second remainder is named again). The second covering (130) may be formed between the first covering (22).

When the inner module 10 and the outer module 20 are coupled, the second seal 130 is brought into close contact with the outer peripheral surface of the rod 11. [ Therefore, even if vibration is applied to the juice drum 400 during the juicing process, the second compaction 130 and the rod 11 are in close contact with each other, so that the gap between the first slit 13 and the rib 22 is kept constant Can be effective.

Figs. 9A and 9B show another modification of the juice drum shown in Fig. 3A or 5A.

As shown in FIGS. 9A and 9B, a juice discharge hole 140 may be formed at an intermediate portion of the outer module 20. The first module 21 and the juice outlet 23 are not formed in the outer module 20 shown in Figs. 12A and 12B. That is, the outer module 20 is formed in a general cylindrical shape with no perforation on its outer circumferential surface. Instead, the outer module 20 is formed as a two-sided cylindrical shape having a lower diameter smaller than the upper diameter, and a step difference surface 141 is formed between the upper cylindrical portion 150a and the lower cylindrical portion 150b. A juice discharge hole 140 is formed in the stepped surface 141. The rib 22 protrudes radially inward from the inner peripheral surface of the outer module 20. [ Accordingly, the juice discharged from the gap at the upper portion of the juice discharge hole 140 can be discharged through the juice discharge hole 140. At this time, since no hole is formed in the outer peripheral surface of the outer module 20, the juice can be prevented from splashing on the inner surface of the drum housing 200.

Meanwhile, up to now, a slit is formed in the inner module and a rib is formed in the inner peripheral surface of the outer module. However, it will be understood from the foregoing description that the same function can be performed even if a rib protruding radially outward is formed on the outer peripheral surface of the rod of the inner module and the rib is inserted into the outer outlet module 23.

According to the first embodiment of the present invention, the juice drum can be easily cleaned and the juicing efficiency can be improved.

In addition, according to the first embodiment of the present invention, it is possible to smoothly convey the material by the screw during the pressing process, increase the juicing rate through the fine grinding and pressing of the material, and smoothly insert the material.

In addition, according to the first embodiment of the present invention, it is possible to prevent the problem that the drainage of the juice drum is interfered with the flow of the juice by preventing the problem that the juice drum is caught in the juice drum during the juicing process.

According to the first embodiment of the present invention, the juice drum is made of a rigid material, so that deformation of the juice drum can be prevented in the juice process. Thus, it is possible to prevent the slit from spreading and to keep the gap between the slits from which the juice is discharged constant.

According to the first embodiment of the present invention, the juice drum is easily assembled and disassembled into the juice extractor, and the juice drum is easily manufactured.

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.

As described above, the juice drum according to the embodiment of the present invention is configured so that the two modules can be coupled in the vertical direction, so that the assembling and disassembling of the two modules is facilitated and the washing is simplified.

Further, it is possible to prevent the debris from being caught in the gap through which the juice is discharged by being formed between the two modules through the first rib jaw and the inclined portion formed in the first slit, and the juicing efficiency can be improved.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the appended claims. It belongs to the scope of design.
