Description

[0001] JUICE SQUEEZING DRUM AND JUICER [0002]

The present invention relates to a juice drum 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.

[ Further, the drive shaft 6 is connected to the shaft of the screw 300 through a hole penetrating the center of the drum housing 200.

The lower support 3 extends in the direction of the juice outlet from the lower portion of the main body 1 and can be formed in a plate shape (in FIG. 1C, the direction of the lower support 3 is not exactly represented as extending in the direction of the juice outlet I did not). On the lower support part 3, a juice cup (not shown) capable of containing juice may be arranged.

As will be described later, the drum housing 200 of the present invention shown in Figs. 1A and 1B replaces the juice drum 400 that receives the screw. More specifically, the outer module 20 constituting the juice drum 400 replaces the drum housing 200. The juice drum 400 houses a screw 300 therein and a driving motor (not shown) of the main body 1 is transmitted to the screw 300 through a driving shaft (not shown). 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.

FIG. 2A (and FIG. 5A) and FIG. 2B (and FIG. 5B) are exploded perspective views of a configuration in which the main body is omitted from the juicer according to the embodiment shown in FIGS. 1A and 1B of the present invention. 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 juicer according to an embodiment of the present invention may include a hopper 100, a screw 300, and a juice drum 400, as shown in Figures 2A (and 5A) and 2B (and 5B) have. A screw 300 is disposed inside the juice drum 400 and the hopper 100 is detachably coupled to the outer module 20 constituting the juice drum 400.

The juice outlet 220 and the juice outlet 230 are formed in the lower part of the outer module 20 constituting the juice drum 400. The juice outlet 220 can be formed in a pipe shape from one side of the juice drum 200 so that the juice can be easily discharged. The debris discharge port 230 may be formed so that debris can be discharged to the side of the outer module 20. The juice outlet 220 can be opened or closed by a juice opening / closing mechanism (not shown), and the juice outlet 230 can be opened or closed by a debris opening / closing mechanism (not shown).

Drum holes 260 are formed in the lower center of the outer module 20 of the juice drum 200. The drive shaft connected to the motor is inserted into the drum hole 260 and connected to the screw 300 so that power can be transmitted 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 that the drive shaft can be inserted.

The screw (300) is rotatably received by receiving a rotational force from a drive shaft, and presses or crushes a juice object. A screw shaft 320 is formed at a lower portion of the screw 300 and an upper portion of the screw shaft 320 is coupled to the screw shaft 320 so as to transmit power. At least one first spiral protrusion 310 is formed on the outer circumferential surface of the screw 300 so as to be in contact with the juice drum 400. 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 at the top of the screw 300 may be greater than the spacing between adjacent first helical projections 310 at the bottom of the screw 300. [ 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 upper portion of the screw 300 is inserted into a shaft hole (not shown) formed in the lower surface of the hopper 100 so that the screw 300 can be rotated in both upper and lower directions of the shaft. Accordingly, the vibration of the screw and the wear of the apparatus can be prevented, and the noise generated when the screw hits the inner wall of the juice drum 400 can be reduced.

Figures 3a-d are views of one embodiment of a juice drum of the present invention. Embodiments of the juice drums of the present invention can be applied to all of the juicers shown in Figs. 1A and 1B. 3A is a perspective view of an inner module according to an embodiment of the present invention, FIG. 3B is a sectional view of a portion "AA" shown in FIG. 3A, and FIGS. 3C and 6D and FIG. Is an exploded perspective view of a juice drum according to one embodiment of the present invention.

As shown in FIGS. 3A to 4D, the juice drum 400 according to the embodiment of the present invention 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. On the other hand, the juice drum 400 should be made of a high strength material which is harmless to the human body and strong enough to withstand the pressure generated during the juicing process and to keep the width of the juice constant. The inner drum 10 and the outer drum 20 can be made integral with each other by using polyetherimide (PEI) and the inner module 10 10 and the outer module 20 can be manufactured by injection molding.

The inner module 10 is formed into 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 side surface at upper and lower portions. The slit 12 may be formed continuously on both sides of the slit and on the upper and lower surfaces of the slit without forming a boundary therebetween. In this embodiment, the width of the slit is fixed and the through- The hole size is also fixed.

Also, the outer module 20 is formed into a cylindrical shape having an open top so as to be detachably coupled to the inner module 10. In the embodiment of the present juice drum, the outer module 20 replaces the drum housing which receives juice juice. The outer module 20 of the present invention is configured to form the ribs 22 on the inner side and receive the inner module 10. At this time, a juice outlet 220 and a debris outlet 230 are formed below the outer module 20. However, the slit as in the inner module 10 is not formed. The juice outlet 220 and the juice outlet 230 may be formed in a pipe or similar shape so that juice and debris can be easily discharged, respectively. A drum hole 260 is formed in the lower center of the outer module 20. The drive shaft may be inserted into the drum hole 260 to transmit power to the screw 300. And a screw 200 and an inner module 10 are seated on the bottom surface of the outer module 20.

The ribs 22 formed on the inner side of the outer module 20 are protrusions including both side surfaces and protruding surfaces and upper and lower surfaces to be inserted into the slit 12 of the inner module 10 when the inner module 10 is engaged with the ribs 22 . The side surface and the protruding surface of the rib, and the upper surface and the lower surface may be formed continuously without being bounded to each other. The ribs 22 define a predetermined fixed gap between both sides of the slit 12 of the inner module 10 and both sides of the rib 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 10 so as to be narrow and long, and juice is filtered out between the gaps formed on the inner module 10 side during juicing. As a result, debris remains inside the inner module 10 of the juice drum 400, and the juice can be separated and discharged to the outer module 20 side. That is, the gap between the slit 12 and the rib 22 serves as a mesh of the conventional mesh structure. Accordingly, only the slit formed in the inner module 10 of the juice drum can be formed without forming a circular fine vortex like the conventional network drum, so that the wastes trapped between the through holes of the slit can be easily cleaned. Accordingly, the two modules can be easily separated from the conventional network drum, so that it is easy to clean, and the problem of clogging of the net hole in the conventional network drum is fundamentally solved, and the brush which had to be provided in the conventional vertical raw- Various parts are not necessary.

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. Such gap spacing is determined to be optimized according to the overall design conditions. In addition, the juice gap can be formed by passing through the slit 12 or the rib (not shown) when the screw 300 can be formed with a long through hole that intersects the spiral 310 of the screw 300 at a predetermined angle when the screw 300 is received in the juice drum 400 22 may be any shape, such as a bar-shaped hole or an egg-shaped hole.

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 diameter of the inner module 10 is smaller than the inner diameter of the outer module 20 so that the rib 22 of the outer module 20 is inserted into the slit 12 of the module 10, The module 20 may have a generally truncated conical shape that tapers downwardly.

The juice drum may have various forms, depending on the type of juicer applied. In an embodiment of the present invention, the inner module 10 and the outer module 20, which serve as a drum housing while accommodating the inner module, are formed to have a similar length and the slit 12 is formed in the inner module 10 And is formed to correspond to the entire length.

As shown in FIGS. 3A and 3C, the inner module 10 of the present invention composed of two modules protrudes radially inward toward the screw at regular intervals along the inner circumferential surface where the slits 12 are not formed A plurality of rib jaws 13 and 14 can be formed. The rib jaws 13 and 14 are formed on the inner peripheral surface of the inner module 10 perpendicularly along the vertical direction.

In this embodiment, since the outer module 20 does not directly interact with the screw 300, the rib jaws 13 and 14, which grind the juice down and assist in the pressing action by interacting with the screw 300, Is formed only in the module (10) and not on the inner surface of the outer module (20). As shown in FIG. 4C, 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 vertically over the entire upper and lower portions of the inner module 10 interacting with the screw.

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.

That is, the screw 300 is received in the inner module 10 and is crushed while being rotated, is sandwiched between the outer surface of the screw 300 and the inner circumferential surface of the inner module 10. At this time, the material that rotates due to the rotational force of the screw 300 can be lowered to the inner module 10 by colliding with the rib jaws 13 and 14. 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.

The rib jaws 13 and 14 may be divided into a first rib jaw 13 having a relatively short height and a second rib jaw 14 having a relatively long protrusion height. 3A and 3C, in an embodiment of the present invention, the first rib jaw 13 has a length shorter than or similar to the length of the slit 12, and the second rib jaw 14 has a length generally equal to the length of the slit 12, As shown in Fig. 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 jaw 14 so that the compressive force is gradually increased to crush the material. The juice generated by the compression of the compressive force is filtered through the gap formed by inserting the rib 22 of the outer module 20 into the slit 12 of the inner module 10 to be discharged and effective juicing is performed. At this time, the material which is crushed by the second rib jaws 14 and pushed down along the spiral bones of the screw is further crushed by the plurality of first rib jaws 13 formed from the lower side while being crushed. At this time, the material is strongly pressed by the applied conveying compressive force, the juice is squeezed, and the juice is ejected and discharged to increase the juice efficiency.

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. At this time, the rib jaws 13 and 14 can be used as members for reinforcing the inner module 10. [ In one embodiment of the present invention, one rib jaw (13, 14) is formed in one knife. In an embodiment of the present invention, the second rib jaw 14, which is formed relatively large, can perform the function of reinforcing the rigidity of the inner module 10. 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. Further, the function of the juice to be pushed downward by the second rib jaw 14 to the bottom of the juice drum 400 is as described above. In addition, the second rib jaw 14 can perform a function of fixing the receiving position of the screw 300 in the juice drum 400 and fixing the juice space with a material pushed down by the pressure during the juicing process have.

The protruding height of the second rib jaw 14 of the inner module 10 may be the same as the height from the upper portion to the lower portion or may be gradually decreased from the lower portion as shown in FIG. 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.

Further, in order to fix the coupling position of the inner module 10 and the outer module 20, the space between the plurality of ribs 22 may be relatively narrow and relatively wide. A surface not formed in the slit of the inner module 20 may be superimposed on a space having a relatively large gap between the plurality of ribs 22. [ The key projection 25 may be formed in a space having a relatively large gap between the plurality of ribs 22.

As shown in FIG. 3C, in the embodiment of the present invention, the outer module 20 corresponds to the outer surface 10-1 (see FIG. 3A) of the surface of the inner module 10 on which the slit 12 is not formed, When the inner module 10 and the outer module 20 are coupled to each other, the first module 10 is guided to the outer module 20 while the guide surface 20-1 without the ribs 22 is formed, And thus the gap is fixed and can not be moved. As shown in FIGS. 2A and 3D, the key protrusion 25 can be formed on a part of the inner circumferential surface of the outer module 20, and the key groove 15 can be formed on the outer circumferential 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.

The first rib jaws 13 protrude in the radial direction of the screw and are vertically formed along the longitudinal direction on the inner circumferential surface of the inner module 10 and are spaced apart from each other along the inner circumferential surface of the inner module 10 As shown in FIG. The first rib jaw 13 is crushed by the second rib jaw 14 by the rotation of the screw, and then the material such as vegetables transferred to the lower portion is finely and uniformly pressed while being crushed by the second rib jaw 14. The projection height of the first rib jaw 13 is lower than the projection height of the second rib jaw 14 and shorter than the length of the second rib jaw 14. [

Also, in a preferred embodiment of the present invention, as shown in FIGS. 3A and 3B, the first rib jaw 13 can be formed close to the upstream edge of the slit 12 in the screw rotating 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. Also, in another preferred embodiment, the first rib jaw 13 may be formed to extend radially inward at an edge formed in the vertical direction of the slit 12. 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. See FIG. 3B for the description of the inclined portion 18. FIG. 3B is a cross-sectional view of the portion "A-A" shown in Fig. 3A. As shown in FIG. 3B, 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. 3B is a cross-sectional view showing the appearance of the juice drum viewed from below and showing the insertion of the rib 22 of the outer module 20 into the slit 12 of the inner module 10. The position of the first rib jaw 13 and the inclined portion 18 will be described in detail with reference to Fig. 3B. 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 from 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 is rotated inside the inner module 10, the debris of the juice to be crushed between the screw 300 and the inner module 10 flows into the first rib jaw 13 In the case of a small amount that can not be exceeded, the debris moves along the first rib jaw 13 to the lower side of the inner module 10.

When the amount of the residue increases to exceed the first rib jaw 13, the residue rides over the first rib jaw 13 and moves 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 rides along the inclined portion 18 formed at the edge of the slit 12 facing the first rib jaw 13 to the adjacent first rib jaw 13 It is prevented that the debris is 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 course of the object to be juiced passing over the first rib jaw 13 is reduced, so that the trapping of debris in the gap can be minimized.

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. By using the drum housing as the second module, .

In another embodiment, the outer diameter of the inner module 10 and the inner diameter of the outer module 20 are relatively matched so that the space between the outer circumferential surface of the inner module 10 and the inner circumferential surface of the outer module 20 gradually widens toward the lower side . The outer diameter of the inner module 10 may be gradually decreased as the outer diameter of the inner module 10 decreases from the upper portion to the lower portion of the inner diameter of the outer module 20 toward the lower portion of the juice drum, One or more stepped portions whose diameters are sharply reduced may be provided. The juice discharged through the gap formed between the slits 12 and the ribs 22 is widened toward the lower side, so that the juice can be smoothly discharged to the juice discharge port 220.

In another embodiment of the present invention, the circumferential width of the juice formed between the slits 12 of the inner module 10 and the ribs 22 of the outer module 20 is preferably 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 a preferred embodiment of the present invention, the width of the rod 11 (the distance between one first slit and the neighboring first slit along the circumferential direction), as seen in Figures 3c and 3d, ) Of the protruding portion 311. As shown in Fig. In this case, the cylindrical module is formed with a through 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 alternately, and the slit 12 is formed And the plate portion 11 which is not formed is defined as "rod ". 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. For this, the inner rod 11 may have a semicircular, elliptical, or trapezoidal cross section.

Also, in one embodiment of the present invention, as shown in FIGS. 3C and 3D, an annular flange portion 16 may be formed at the lower end of the inner module 10. The material pushed down by the spiral bone of the screw into the inner side of the inner module 10 is more reliably made by the flange portion as the discharge is stagnated and the juicing efficiency is improved. The flange portion 16 also serves to support the width of the slit 12 to be fixed. Since the lower side of the inner module 10 is supported by the flange portion 16, the width of the slit 12 is not changed by the pressing force during the juicing process. In addition, the debris of the juice to be crushed between the screw 300 and the inner module 10 is moved downward by the first rib jaw 13 and the second rib jaw 14, And a guiding jaw 27-1 formed with an inclined projection extending from the lower end of the two ribs 14 is formed to serve as a guiding jaw for smooth movement of the debris to the debris discharging port 230. [

As shown in FIG. 3D, in another embodiment of the present invention, the flange portion 16 is formed at the lower end of the inner module 10 and the flange portion and the connecting end of the side lower portion of the inner module 10 are provided with a first step (119) may be formed. Also, as shown in FIG. 3C, the second step 226 may be formed on the lower side of the rib 22 of the outer module 20. The first step 119 may be seated and supported on the second step 226 of the outer module 20. At this time, the flange portion can be inserted and fastened below the second step.

3C, the second step 226 slightly protrudes radially inward, and the first step 119 is seated in the second step 226, so that the bottom surface of the inner module 10 is positioned on the outer side Or may be positioned so as not to abut the inner bottom surface of the module 20. In this way, a larger space is provided in the lower portion of the outer module 20 so that the juice efficiency is increased.

As shown in FIGS. 3C and 3D, a debris discharge hole 110 is formed at one side of the lower side of the inner module 10 so that the discharged straw can be completely discharged while the discharge is stagnated by the flange portion 16 .

As shown in FIG. 3D, a residue discharge adjuster 111 may be additionally provided in the residue discharge hole 110 at this time. The debris discharger 111 may be hinged to the inner module 10. The debris discharge regulator 111 is composed of an elastic packing so that the debris can be pushed out of the debris discharge regulator 111 and discharged through the debris discharge port 230 during the juicing process. Since the debris discharge regulator 111 is hinged to the debris discharge hole 110 when the inner module 10 is cleaned, the debris pushed into the debris discharge hole 110 pushes up the packing of the debris discharge regulator 111 It can be easily removed automatically.

Will be described in more detail with reference to FIGS. 4 to 10. FIG.

4B to 4D are partial sectional views of the juice drum as one embodiment of the present invention. FIG. 4B is a top view of the juice drum as one embodiment of the present invention. 4C is a cross-sectional view taken along the line A-A of FIG. 4B, and FIG. 4D is a cross-sectional view taken along the line B-B of FIG. 4B. 4B, 4C and 4D, the cross section in the direction of " AA "is such that a section on the side of the juice outlet port 220 is visible. , The juice discharge passage and the debris discharge passage are shown in a clear view.

Referring to FIG. 4A, which is a perspective view of the juice drum cut in the AA 'direction, a juice discharge groove 297 is formed on the bottom surface of the outer module 20 on the outer side in the radial direction around the drum hole 260. A debris discharge groove 298 is formed on the upper surface of the flange 16 formed at the lower end of the inner module 10. The juice discharge groove 297 is in communication with the juice discharge port 220 and the debris discharge groove 298 is in the form of debris And communicates with the discharge hole 110 and the residue discharge port 230.

The juice discharged through the gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 due to the interaction with the screw as shown in Fig. And is discharged through the juice outlet 220 (see arrows in Fig. 4C).

4D, the residue left between the inner module 10 and the screw 300 flows along the residue discharge groove 298 and flows through the residue discharge hole 110 and the residue discharge hole 230 .

At this time, an annular flange portion 16 extending radially inwardly at the lower end of the inner module 10 flows along the waste discharge groove 298 and is discharged to the waste discharge port 230 through the waste discharge hole 110 . That is, the time during which the juice object stays between the screw 300 and the inner module 10 increases, which makes it possible to sufficiently juice the juice object, thereby increasing the juice efficiency.

Referring to FIG. 4C, the flow path of the juice is described as follows. The outlet of the juice extruded through the gap between the inner module 10 and the outer module 20 is well illustrated. When the material is injected into the hopper 100, the screw 300 is rotated to press the material down while discharging the juice into the gap between the juice drums 10 and 20 in the process.

Referring to FIG. 4D, a path for discharging debris pushed down through the gap between the inner module 10 and the screw 300 is shown. Although the debris discharge hole 110 formed at the lower side of the inner module 10 is not shown, the debris is discharged through the discharge hole 110 formed in the inner module lower end flange 16 and attached to the lower side surface or the bottom surface of the inner module The waste discharge can be automatically adjusted according to the discharge pressure by the packed seal 239.

A drum hole 260 is formed at the center of the inner bottom surface of the outer module 20. (Not shown) for waterproofing on the inner circumferential surface of the drum hole 260 or may include a cylinder protruding and inserted into the inner central space of the screw 300 according to design needs. The first step 119 (see FIG. 3D) formed at the lower end of the inner module 10 may be supported on the second step 226 formed on the inner circumferential surface of the outer module 20 as described above. (See FIG. 3C) formed at the lower end of the rib 22 of the outer module 20, as shown in FIG.

Guide grooves 291 and 292 into which the lower ring 390 of the screw 300 is inserted so that the screw 300 can be rotatably supported by the upper surface of the flange 16 formed at the lower end of the inner module 10 The guiding jaw 294 and the like can be provided. The lower ring 390 of the screw 300 is preferably formed by a first lower ring 391 and a second lower ring 392 so that the first lower ring 391 and the second lower ring 392 The first guide groove 291 and the second guide groove 292, which are inserted and supported, can be formed. In this way, while the screw 300 is rotatably fixed and supported, the pressure of the debris or the juice drops, so that the debris or juice does not enter the drive shaft.

The second guiding jaws 294 close to the central axis can be formed in an annular shape on the inner surface of the bottom flange portion of the inner module 10 so that the debris can not escape into the juice discharge passage.

5b, the first screw packing 330 may be coupled to the outer circumferential surface of the screw shaft 320 in another embodiment of the present invention. 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, it is possible to prevent the juice from flowing into the inside of the drum hole 260 during the juicing process.

A packing groove 340 may be formed between the first lower ring 291 and the second lower ring 291 on the lower outer circumferential surface of the screw 300. The packing groove 340 may be formed with a second screw The packing 395 (see Figs. 5B and 4C and 4D) can be combined. The second screw packing 395 seals the inside of the seating portion 293 when the packing groove 340 is seated in the seating portion 293 formed in the inner lower side of the inner module 10. Accordingly, it is possible to prevent the debris from flowing into the juice outlet 220 during the juicing process.

One embodiment of the inner module 10 and the outer module 20 will be described in more detail with reference to FIG. A rib 22 may be formed on the inner circumferential surface of the outer module 20. A slit is not formed on the inner peripheral surface of the outer module 20 according to one embodiment of the present invention. That is, the inner peripheral surface of the outer module 20 is formed of a continuous surface.

On the other hand, when the inner module 10 and the outer module 20 are coupled, the rib 22 of the outer module 20 is inserted into the slit 12 of the inner module 10. A predetermined gap can be formed by inserting the ribs 22 into the slits 12. [ The size of the gap may be constant or non-constant. The debris collected at the lower inner side of the inner module 10 is transferred to the outer module 20 through the debris discharge hole 110 and is finally formed at the lower side of the outer module 20 And can be discharged through the residue discharge port 230.

In another embodiment of the present invention, the lower side juice gap of the juice drum, in which the juice is filtered by relatively matching the widths of the slits 12 and the ribs 22, may be narrower than the upper side juice gap. 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 So that the material gradually compresses and the granules become smaller, and the compression force due to the compression of the material gradually becomes larger as it goes down. 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.

In this way, excessive pressure on the upper part of the juice drum can be reduced, and the granules of the material, which becomes smaller due to the compressive force increasing toward the lower part, can be more easily filtered out, and the juice overflowed by the lower side debris, The juice efficiency can be improved. The width of the through hole of the slit 12 of the inner module 10 may be increased toward the lower side and the width of the rib 22 of the outer module 20 may be increased toward the lower side. In the embodiment of the present invention, as shown in FIGS. 5A to 8, the upper side width of the slit 12 is formed to be smaller than the lower side width of the slit 12. Further, the width of the slit 12 may be made narrower toward the upper side. At this time, for example, the width of the ribs 22 of the outer module 20 may be narrower than the width of the slits 12 toward the upper side so that the wings may be formed wider toward the upper side.

It is also preferable that a step 121 is formed in the slit 12 of the inner module 10 and the upper side slit width is smaller than the lower side slit width with respect to the step portion 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. The width of the slit 12 of the inner module 10 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, And can be widened toward the upper side with respect to the stepped portion 24.

In another embodiment of the present invention, as shown in FIG. 6, the width of the upper side rib 22 of the outer module 20 may be smaller than the width of the lower side rib 22. Further, the width of the ribs 22 may become narrower toward the upper side. The rib 22 may be provided with a step 24 so that the width of the rib 22 on the upper side relative to the step 24 is smaller than the width of the rib 22 on the lower side. Furthermore, the width of the rib 22 on the upper side of the stepped portion 24 may become narrower toward the upper side.

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. 6, the object to be juiced is caught by the stepped portion 24, and accumulation of the object to be juiced in the gap can be prevented.

5A to 10, the invention related to the residue discharge regulator will be described in more detail.

6 and 7 are exploded perspective views of a juice drum according to an embodiment to which a debris discharge regulator is applied, and Fig. 8 is an exploded perspective view of a juice extractor according to an embodiment of the present invention, 1 is a partial cross-sectional perspective view of a juice drum according to one embodiment to which a drain controller is applied.

First, referring to Figs. 5 to 8, a juicer to which a juice drum is applied will be summarized as a whole. However, the contents related to the main body portion in which the drive motor and the speed reducer are disposed are the same as those already described above, so they are omitted.

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 an inner module 10 and an outer module 20. The juice drum 400 may be constructed by combining the inner module 10 and the outer module 20 and the inner module 10 and the outer module 20 may be detachably coupled to each other. 6, the inner diameter D2 of the outer module 20 may be larger than the outer diameter D1 of the inner module 10 (D2> D1). Accordingly, the inner module 10 can be smoothly inserted and coupled to the outer module 20.

The inner module 10 is generally cylindrical in shape, and the upper and lower sides thereof can be opened. A plurality of slits 12 are formed in the inner module 10. On the other hand, the first rib jaw 13 and the second rib jaw 14 may be formed on the inner peripheral surface of the inner module 10. The material can be squeezed or crushed by the interaction of the first spiral protrusion 310 and the rib jaws 13, 14 in accordance with the rotation of the screw 300 in the juice module. Further, it is preferable that the first rib jaw 13 is formed adjacent to the slit 12.

On the other hand, ribs 22 are formed on the inner peripheral surface of the outer module 20. These ribs 22 may be inserted into the slits 12 formed in the inner module 10. Here, no slit is formed on the inner peripheral surface of the outer module 20. That is, the inner circumferential surface of the outer module 20 is configured as a continuous surface so as to surround the inner module 10. At this time, the ribs 22 may not be formed on the inner circumferential surface of the outer module 20 corresponding to the surface on which the slits 12 are not formed in the inner module 10. The main surface on which the slit of the inner module 10 is not formed can be positioned in this space and the key projection 25 can be formed. At least one key groove 15 may be formed around the upper outer circumferential surface of the inner module 10 corresponding to the key protrusion 25 so that the key protrusion 25 is inserted.

When the embodiments of the present invention are combined with the inner module 10 and the outer module 20, the ribs 22 are inserted into the slit 12. That is, by inserting the ribs 22 into the slits 12, a predetermined gap can be formed between the slits 12 and the ribs 22. Through these gaps, the juice juice can be drained. As a result, the juice can be separated and discharged from the juice drum 400 to the outer module 20 side, with the debris remaining on the inner side of the inner module 10. On the other hand, an annular flange 16 may be formed on the lower side of the inner module 10.

A juice outlet 220 and a debris outlet 230 are formed in the lower portion of the outer module 20. The juice outlet 220 may be formed in a pipe shape from one side of the juice drum 400 so that the juice can be easily discharged. The debris discharge port 230 may be formed so that debris can be discharged to the outside of the outer module 20. On the other hand, a residue discharge regulator 719a may be further coupled to the residue discharge hole 719. [ That is, the residue generated in the juicing process collects in the inner lower part of the inner module 10, pushes the debris discharge regulator 19a from the debris discharge hole 719 and goes out through the debris discharge port 230 of the outer module 20 to the outside Can be discharged.

With reference to Figures 5A-8, one embodiment related to a debris exhaust regulator will be described in more detail. A fitting portion 11a is formed on one side of the lower portion of the outer peripheral surface of the inner module 10 and a debris discharge hole 719 communicating with the inside of the inner module 10 is formed on the outer circumferential surface of the inner module 10 at a lower portion of the fitting portion 11a May be formed.

A fitting groove 28 is formed at one side of the lower portion of the inner circumferential surface of the outer module 20 so as to fit the fitting portion 11a at the time of coupling the inner module 10 and the outer module 20 corresponding to the fitting portion 11a .

Accordingly, when the inner module 10 is inserted into the outer module 20, the fitting portion 11a is inserted into the fitting groove 28, thereby guiding the movement of the inner module 10, The inner module 10 can be properly positioned inside the inner module 10.

On the other hand, a residue discharge regulator 719a may be further coupled to the residue discharge hole 719. [ The upper portion of the drainage regulator 719a may be hinged to the fitting portion 11a so as to selectively open and close the waste discharge hole 719 by being rotated upward from the outer peripheral surface of the inner module 10. [ Here, the debris discharge regulator 19a may be constituted by a packing.

That is, the debris generated in the juicing process collects in the inner lower part of the inner module 10 and pushes the debris discharge regulator 719a from the debris discharge hole 719 to the outside through the debris discharge port 230 of the outer module 20 Can be discharged. At this time, the debris discharge regulator 719a may be made of an elastic member and its one side may abut against the protrusion of the drum housing to resist, thereby allowing the debris to be automatically discharged only when the set pressure is exceeded.

When the user removes the inner module 10 from the outer module 20 and then rinses the inner module 10, the user rotates and lifts the debris discharge regulator 719a hinged to the fitting portion 11a so that the debris discharge hole 719 can be easily removed.

5 and 6, the first screw packing 330 may be coupled to the outer circumferential surface of the screw shaft 320 in the present invention.

The first screw packing 330 closes the outer circumferential surface of the drum hole 260 when the screw shaft 320 is inserted into the drum hole 260. Accordingly, it is possible to prevent the juice from flowing into the inside of the drum hole 260 during the juicing process.

In addition, a packing groove 340 having a wider diameter than the first screw packing 330 may be formed under the screw 300.

8, the guide groove 290 may be formed on the lower inner surface of the inner module 10 so that the packing groove 340 is seated.

When the screw 300 is inserted into the inner module 10, a seal is formed between the guide groove 290 and the packing groove 340 so as to seal the gap between the guide groove 290 and the packing groove 340. 2 screw packings can be combined.

That is, when the packing groove 340 is seated in the guide groove 290 formed on the lower inner surface of the inner module 10, the second screw packing hermetically seals the inside of the guide groove 290. Accordingly, it is possible to prevent the debris from flowing into the juice outlet 220 during the juicing process.

9 and 10 are perspective views of an inner module for a juice drum according to another embodiment to which a debris discharge regulator is applied. 9 and 10, another embodiment to which the debris discharge regulator is applied will be described in detail.

9, another embodiment of the inner module 40 has the same outer shape, structure, shape, and characteristics as those of the above-described embodiment, except that the installation positions of the debris discharge hole and the debris discharge controller are different, A detailed description thereof will be omitted.

In another embodiment of the present invention, a fitting portion 48 is formed at one side of the lower portion of the outer peripheral surface of the inner module 40, and a debris discharge hole 49 communicating with the inside of the inner module 40 is formed at the lower end of the fitting portion 48. [ Can be formed.

An annular flange 46 connected to the fitting portion 48 is formed at the lower end of the inner module 40. A debris discharge regulator 49a is provided at the lower end of the fitting portion 48 corresponding to the debris discharge hole 49, The engaging groove 49b can be formed.

Here, the engaging groove 49b may be recessed upward from the lower surface of the flange 46 so that the debris discharge regulator 49a is engaged and smoothly closes the debris discharge hole 49.

Accordingly, the debris discharge regulator 49a may be hinged to the radially inner one end of the coupling groove 49b to selectively open and close the debris discharge hole 49 by being rotated to the lower portion of the inner module 40.

That is, when the residues generated in the juicing process gather more than a certain amount in the inner lower part of the inner module 40, the debris pushes the debris discharge regulator 49a from the debris discharge hole 49. At this time, the residue discharge regulator 49a may be made of an elastic member and its one side may abut against the projection of the drum housing to resist, so that the residue can be discharged automatically only when the set pressure is exceeded.

10, the debris discharge regulator 49a is rotated downward by the debris discharged from the debris discharge hole 49 to open the debris discharge hole 49 to discharge the debris to the outer module 20 To the outside of the outer module 20 through the waste outlet 230 of the outer module 20.

In addition, when the user separates and cleans the inner module 40 according to another embodiment of the present invention as seen from the outer module 20, the user pushes the debris discharge adjuster 49a hinged to the engaging groove 49b downward So that it is possible to easily remove the debris that can be caught in the residue discharge hole 49.

As described above, according to the embodiment of the present invention, the juice drum 400 constituted by the two inner modules and the outer modules 10 and 20 can be easily cleaned and the juicing efficiency can be improved.

In addition, according to the embodiments of the present invention, it is possible to smoothly transfer the material by the screw 300 during the pressing process, increase the juicing rate through the fine grinding and pressing of the material, .

In addition, according to the embodiments of the present invention, it is possible to prevent the juice drum 400 from being trapped in the juice drum 400, thereby preventing the flow of the juice juice from being disturbed by the debris.

Further, according to the embodiments of the present invention, deformation of the juice drum 400 can be prevented during the juicing process. Thereby, it is possible to prevent the slit 12 from being opened and to keep the interval between the slits 12 from which the juice is discharged constant.

Further, according to the embodiment of the present invention, the assembling and disassembling and manufacturing of the juice drum 400 constituted in the juicer can be facilitated.

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.
