BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a juice drum and a juicer using the same. More particularly, the present invention relates to a juice drum composed of two modules and a juicer using the same.

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 juicer includes a driving unit for providing rotational force; A drum housing having a driving shaft for receiving rotational force from a driving unit; A screw connected to the driving shaft and pressing and grinding the juice object by a screw spiral formed in a part of the screw; And a juice drum for separating the juice made by the screw. 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, the juice is easily clogged by the juice object, and thus the juicing efficiency is low. Further, since the mesh is formed closely, there is a problem that it is difficult to clean the juice object put on 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.

1 to 4, the juicer according to an embodiment of the present invention may include a main body 1, a hopper 100, a screw 300, and a juice drum 400.

The juice extractor according to the present invention is also referred to as a juice drum including a drum housing. However, for convenience of explanation, the drum housing and the juice drum are separately described.

The body part 1 may include an upper support part 2 and a lower support part 3. [ A driving motor for generating a driving force and a speed reducer (not shown) for transmitting the driving force to the driving shaft are disposed in the main body 1.

In this embodiment, the driving motor and the speed reducer are constituted, but the driving motor and the speed reducer may be constituted by a low speed motor.

The upper support portion 2 may be formed in a shape corresponding to the outer circumferential surface of the drum housing 200 to support the lower portion of the drum housing 200.

The lower supporting part 3 extends to one side from the lower part of the body part 1 and may be formed in a plate shape. A debris cup (not shown) capable of holding debris can be disposed on the lower support portion 3.

The speed reducer serves to change the high-speed rotation of the driving motor to a low speed and can be disposed inside the upper support portion 2. [

The hopper 100 is detachably coupled to the drum housing 200 in a configuration in which the juice (for example, vegetables, grains, fruits, etc.) is temporarily received and guided to the juice drum 400.

The drum housing 200 is formed in a cylindrical shape having an upper surface opened and an inner space formed therein, and is mounted on the upper portion of the main body 10. In addition, a juice outlet 220 is formed on one side and a debris outlet 230 is formed on the other side.

The juice drum 400 and the screw may be disposed in the inner space, and the hopper 100 may be coupled to the opened upper surface.

The drum housing 200, together with the juice drum 400, is a core structure of the present invention, and a detailed description thereof will be given later on after the juice drum 400.

The screw 300 is connected to the drive shaft 6 of the driving motor and the upper side of the screw 300 is coupled to the coupling part 110 of the hopper 100. The screw 300 receives rotational force generated by the driving motor through the driving shaft 6 The juice object is crushed or crushed by rotating motion.

In addition, when the screw 300 is placed inside the juice drum 400 to be described later, the space (space) with the juice drum 400 is formed to be narrowed downward to a certain point.

In addition, a plurality of screw spirals 310 are formed in the screw 300 at a portion contacting the juice drum 400. The juice is pressed by the screw spiral 310 in a space (space) formed between the screw 300 and the juice drum 400 and is conveyed downward.

In addition, the screw spiral 310 formed on the screw 300 is formed with a relatively large gap by forming a single screw thread on the upper side. In addition, a plurality of screw spirals 310 are formed on the lower side so as to have a relatively narrow gap.

That is, the upper side performs the function of crushing the juice object, and the lower side performs the function of crushing and pressing. As a result, the juice is moved from the upper side to the lower side by the rotation of the screw 300, and the juice is squeezed between the screw spiral 310 and the inner surface of the inner module 10 to be described later.

The juice drum 400 is a core structure of the present invention, and can be squeezed or crushed by interaction with the screw 300 as a hollow cylindrical or frusto-conical shape.

In addition, the juice drum 400 may be constituted by a combination of the inner module 10 and the outer module 20. [

Here, the inner module 10 and the outer module 20 may be made of a material such as polyetherimide (PEI).

The inner module 10 is generally cylindrical in shape and can be opened up and down. Here, the inner module 10 includes a plurality of inner plate portions 11, and a plurality of slits 12 are formed by a plurality of inner plate portions 11.

Here, the plate portion is referred to as a "plate portion" for the sake of convenience of description, and the plate portion in which the slit is not formed is defined as a "plate portion" when the hole portion in which the slit is formed in the cylindrical module and the plate portion in which the slit is not formed.

Further, the slit 12 is not limited to a bar-shaped hole or an oval-shaped hole, as long as the above-described screw 300 is seen to cross the spiral of the screw 300 when the screw 300 is received in the juice drum.

The width of the slit 12 on the upper side of the slit 12 may be smaller than the width of the slit 12 on the lower side. 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 width of the slit 12 on the upper side relative to the step 121 may be smaller than the width of the slit 12 on the lower side.

In addition, a first rib jaw 13 may be formed to protrude from the inner circumferential surface of the inner side plate 11. In this embodiment, the first rib jaws 13 are formed in a protruding strip shape, but they can be deformed in any form contacting the screw spiral.

The first rib jaw 13 can be pressed or crushed by interaction with the screw spiral 310 as the screw 300 rotates.

If the first rib jaw 13 is not provided, the juice object may not go down and stagnate, or the pressing force or the crushing force may be low or not.

The first ribs 13 may protrude radially inward from corners of the first slits 12 formed in the vertical direction.

The height of the first rib jaw 13 may be longer than the width (or width) of the slit 12.

The inner side surface of the inner side plate 11 may be provided with a second rib jaw 14 protruding along the longitudinal direction thereof.

The second rib jaw 14 can function to reinforce the rigidity of the inner module 10 and can guide the juice object into the juice drum 400.

In addition, the second rib jaw 14 may adjust the position of the screw 300 and adjust the juice space.

The second rib jaw 14 functions to transfer the material to be supplied into the juice drums 400 to the bottom and crush the juice.

For this purpose, the second rib jaw 14 may be formed vertically in the vertical direction on the inner peripheral surface of the inner module 10 (or the inner surface of the inner plate portion 11).

The protrusion height of the second rib jaw 14 may be formed to have the same height from the upper portion to the lower portion of the inner module 10 but preferably is formed to be gradually lowered from the upper portion of the inner module 10 to the lower portion thereof .

The second rib jaw 14 is formed so as to be inclined downward from the upper portion of the inner module 10 toward the lower portion and has a stepped portion 14-1 protruding toward the screw 300 at an intermediate portion thereof .

The stepped portion 14-1 can be variously modified in its position, number, or protruding height according to the shape of the screw 300 and the design conditions of the screw spiral 310. [

The number and arrangement of the second rib jaws 14 can be variously changed as necessary in consideration of the design conditions and efficiency of the juice.

In the embodiment of the present invention, the formation direction of the second rib jaw 14 is described as being perpendicular to the vertical direction of the inner module 10, but the scope of the present invention is not limited thereto.

The second rib jaw 14 is formed so as to intersect with the screw thread 310 of the screw 300 so that the second rib jaw 14 is inserted into the screw 300 by the interaction of the screw 300 and the second rib jaw 14 of the inner module 10 The juice may be formed to have a constant slope so as to be pulverized while being conveyed downward.

On the other hand, the operation according to the length of the first rib jaw 13 and the second rib jaw 14 will be described.

The first rib jaw 13 is accommodated in the inner module 10 and is conveyed downward by the rotation of the rotating screw 300. The first and second rib jaws 13, It carries out the function of crushing by car.

To this end, the first rib jaw 13 is formed on the inner bottom surface of the inner side plate 11. That is, the first rib jaws 13 may be formed to have a shorter length in the vertical direction than the second rib jaws 14.

As a result, the second rib jaw 14 is formed entirely below the inner side surface of the inner side plate 11, and the first rib jaw 13 can be formed only up to a predetermined height from the lower side of the inner side plate 11. [

If the first rib jaw 13 is formed in the middle portion of the inside plate 11, the material is finely formed at the intermediate portion of the inside plate 11 by the first rib jaw 13 and the screw 300 The object of the juice is not caught by the second rib jaw 14 at the lower part of the inner plate 11 and is rotated together with the screw spiral 310 of the screw 300 because the particle size of the juice object is sharply reduced.

Therefore, the juice can not be smoothly conveyed downward along the screw spiral 310 of the screw 300, and the inside of the inner plate 11 becomes stagnant.

When the object to be juiced is stagnated inside the inner plate 11, the object to be juiced is further increased due to the object of the juice to be added, and there is inconvenience that the object to be juiced must be pressed by using a separate tool do.

In order to prevent such a problem from occurring, the first rib jaw 13 according to the embodiment of the present invention may be formed at the lower portion of the inner side plate 11, so that the particle size of the object to be juiced does not change abruptly, So that the juice is smoothly conveyed downward by the screw spiral 310 and the second rib jaw 14 and the juice is sucked by the first rib jaw 13 from the lower part of the inner side plate 11 And can be further finely pulverized.

The first ribs 13 are formed at the lower portion of the inner plate 11 so that the juice can be smoothly conveyed from the upper portion of the inner plate 11 to the lower portion by the screws 300 and the second ribs 14, The pressure due to the juice to be juiced of the inner plate portion 11 and the screw 300 gradually increases. The juice sucked from the juice object by this pressure can be smoothly discharged through the gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20.

The juice object which is firstly pulverized while being transferred to the lower portion is further finely pulverized by the first rib jaw 13 formed at the lower portion of the inner plate portion 11 and is further finely pulverized between the screw 300 and the inner plate portion 11 The juice is pushed upward and the juice is discharged through a gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 by the pressure, So the juice efficiency is increased.

Accordingly, a gap is formed at the time of coupling the inner module 10 and the outer module 20, and the gap is gradually increased radially outward, so that the juice can be smoothly discharged. In addition, the inner plate 11 may have a semicircular or trapezoidal cross section.

The plurality of inner plate portions 11 may include an inner plate portion 11 having a relatively narrow width and an inner plate portion 11 having a relatively wide width.

That is, a relatively narrow space and a relatively large space may be formed between the plurality of ribs 22 to fix the coupling position of the inner module 10 and the outer module 20. The inner plate portion 11 having a relatively large width can be inserted into a space having a relatively large gap between the plurality of ribs 22.

The first rib jaw 13 is formed on the inner surface of the inner plate portion 11 having a relatively narrow width and the second rib jaw 14 is formed on the inner surface of the inner plate portion 11 having a relatively wide width. .

The end face of the inner side plate 11 may have a shape which widens inward in the radial direction of the inner module 10.

A locking step 111 is formed on the lower side of the inner side plate 11 and an annular inner flange 16 is formed on the radially inner side.

The latching jaw 111 is configured to engage with a latching end 211 formed on the outer flange 27 of the outer module 10 to be described later and has a function of fixing the coupling between the inner module 10 and the outer module 20 .

The inner flange 16 supports the plurality of slits 12 formed in the inner side plate 11 so as to have a fixed width so that the width of the slit 12 does not change during the juicing process.

In addition, the upper surface of the inner flange 16 is formed to be inclined downwardly in the radially outward direction, thereby facilitating juice discharge and improving the juicing efficiency.

If the lower end of the inner module 10 is completely opened, the debris is immediately discharged downward. However, if the inner flange 16 is formed at the lower end of the inner module 10, the debris can be temporarily stagnated to further enhance the juicing efficiency .

The inner flange 16 may be directly coupled to the inner side surface of the inner side plate 11 although the inner flange 16 is formed on the inner side of the engaging step 111 in the present embodiment.

A coupling protrusion 19 is formed on the lower portion of the inner plate 11 and the coupling protrusion 19 penetrates the coupling groove 29 of the outer module 20 to be described later, Can be supported by the surface.

The engaging projection 19 may be formed to protrude downward from the inner flange 16 or may be formed as an upwardly recessed groove.

A helical guide jaw (16-1 in Fig. 4A) may be formed on the upper surface of the inner flange 16 so as to be directed toward the center.

In this case, a helical guide jaw 16-1 extending from the second rib jaw 14 toward the center of the inner module 10 is formed on the upper surface of the inner flange 16 so that the debris is caught and accurately guided downward, .

The helical guide jaw 16-1 may be formed to extend from the second rib jaw 14 and be inclined at a predetermined angle in the rotating direction of the screw 300. [

That is, 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 guiding jaws 16-1 formed of slanting protrusions serve to guide the debris to the scum discharging port.

On the other hand, a key groove 15 may be formed in a part of the outer side surface of the inner side plate portion 11. A key projection (25) formed on the inner side surface of the outer side plate (21) to be described later is fitted in the key groove (15), so that the coupling position of the key plate can be fixed.

Next, the outer module 20 will be described. The outer module 20 includes an outer plate 21 and a rib 22 protruding from the inner surface of the outer plate 21 in a generally cylindrical shape.

The outer plate portion 21 is formed to be detachable (detachable) by receiving the inner module 10 therein. That is, the outer module 20 may be coupled to the inner module 10 when the inner module 10 is coupled with the inner module 10. At this time, the outer module 20 can cover the inner module 10. [

The rib 22 is inserted into the slit 12 of the inner module 10 to form a gap with the slit 12 and may be protruded from the inner surface of the outer plate 21.

However, it is not limited to any shape as long as it can be inserted into the slit 12 of the inner module 10 to form a gap. In addition, the ribs 22 may be separately configured to be coupled to the outer plate 21.

At this time, the width of the rib 22 on the upper side may be smaller than the width of the rib 22 on the lower side so that the width of the rib 22 becomes narrower toward the upper side.

The rib 22 is formed with a step portion 24. The width of the rib 22 on the upper side relative to the step portion 24 may be smaller than the width of the rib 22 on the lower side.

In addition, a plurality of juice discharge holes 23 may be formed along the plate surface of the outer side surface of the outer side plate portion 21.

Here, the bottom surface of the juice discharge hole 23 is formed to be inclined downward to the outside in the radial direction, thereby facilitating juice discharge and improving the juicing efficiency.

On the other hand, a support protrusion 26 may be formed on the upper side of the outer side plate portion 21. The support protrusion 26 may be seated in a support groove (210 in FIG. 3) formed in the inner circumferential surface of the drum housing 200.

The outer protrusion 26 is seated in the support groove 210 so that the outer side of the outer module 20 is separated from the inner side of the drum housing 200 and the outer module 20 is supported by the screw 300 So that it can be fixed without being rotated in the rotating direction.

Here, the support protrusions 26 may be configured to support at least two points in order to prevent the outer module 20 from rotating.

In order to stably engage the support protrusions 26, four circumferentially spaced apart support protrusions 26 are formed at equal intervals, and the support recesses 210 of the drum housing 200 are formed at the same positions as the support protrusions 26 .

Further, the support protrusions 26 are formed on the upper outer circumferential surface of the upper side of the outer side plate portion 21. Accordingly, when the user places the outer module 20 inside the drum housing 200, the support groove 210 can be easily recognized by the user's eyes, thereby improving the assemblability.

In addition, if the support protrusions 26 are seated only in the support grooves 210, the outer module 20 can be fixed, and the assemblability can be remarkably improved.

On the other hand, a key projection 25 is formed on the inner side surface of the outer side plate portion 21 to be fitted into the key groove 15 of the inner module 10 by a method of fitting or sliding.

The coupling position between the inner module 10 and the outer module 20 can be fixed by fitting the key groove 15 and the key projection 25. [

That is, the coupling position, rotation, and tilting of the inner module 10 and the outer module 20 can be limited by the engagement of the key groove 15 and the key projection 25, and the size of the gap can be maintained .

Further, an annular outer flange 27 may be formed on the lower side of the outer main body 21. The debris can not directly move to the lower side of the inner module 10 by the outer flange 27 and the debris temporarily stays on the upper surface of the outer flange 27. [

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 can be increased.

On the other hand, on one side of the outer flange 27, an engaging groove 29 through which the engaging projection 19 of the inner module 10 communicates is formed.

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 engaging projections 19 and engaging grooves 29, the projections can be deformed into grooves, the grooves can be deformed into projections, and the means for securing the inner module 10 and the outer module 20 can be modified But the present invention is not limited to the coupling grooves and coupling projections described.

Further, the outer flange 27 is formed with a latching end 211 on the lower side thereof. When the outer module 20 surrounds the inner module 10 and the outer module 10 is mounted on the inner module 10 As shown in Fig.

Next, a gap formed by the combination of the inner module and the outer module will be described.

Fig. 7 is a coupling state view of Fig. 5, and Fig. 8 is a coupling state view of Fig. Referring to FIGS. 7 and 10, when the inner module 10 is accommodated in the outer module 20, the outer module 20 can surround and couple the inner module 10.

At this time, a rib 22 protruding from the inner side surface of the outer body 20 is inserted into the slit 12 between the inner main bodies 11 to form a predetermined gap a. Here, the size of the gap a may be constant or not constant. Also, the gap a may be formed so as to communicate with a spacing space b described later.

The gap (a) is formed to be wider radially outward so that the juice can be smoothly discharged.

In addition, the gap a may be formed such that the upper side gap a1 is formed to be larger than the lower side gap a2 in the longitudinal direction, and narrows from the upper side to the lower side. That is, since the pressure is more applied to the lower side of the juice drum 400 during the pressing process, the lower side gap of the juice drum 400 is preferably narrow.

For example, when the width of the slit 12 between the upper side of the inner side plate 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, The size can be widened toward the upper side with respect to the stepped portion 24.

In the case of a hard juice object such as a carrot, the juice may be discharged through a gap formed in the lower part in the compression process. In the case of a juicy object such as tomato, the juice may be discharged not only in the gap formed in the lower side but also in the gap formed in the lower side during the pressing process, as the object to be juiced is raised to the upper wide gap. As described above, when the size of the gap (a) is not constant, the fruit juice efficiency can be improved for both the juice object such as carrot and the juice object such as tomato.

The size of the gap a 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 a during the juicing process. In this case, the object to be juiced is caught by the stepped portion 24, and accumulation of juice objects in the gap a can be prevented.

Next, the spacing space b formed by the coupling of the inner module 10 and the outer module 20 will be described.

FIG. 9 is a longitudinal sectional view taken along the line I-I 'of FIG. 7, and FIG. 10 is a longitudinal sectional view taken along the line II-II' of FIG. 9 and 10, when the inner module 10 is accommodated in the outer module 20, a space is formed between the outer surface of the inner plate 11 and the inner surface of the outer plate 21, (b) may be formed.

Here, the spacing space (b) serves as a flow path through which the juice discharged through the gap (a) can move.

At this time, at least a part may be linearly or surface-contacted from the upper end where the outer side plate portion 21 and the inner side plate portion 11 come into contact with each other downward to a certain point, and a spacing space b may be formed after a certain point. A space in which the juice moves as in the above-mentioned gap (a) may be formed at a portion where the above-mentioned at least part is linearly or surface-contacted.

Further, the spacing space b may be formed to be wider or equal to the lower side.

Fig. 11 is a longitudinal sectional view of the combined state of the screw and the juice module, and Fig. 12 is a partially enlarged view of Fig. 11 and 12, the spacing space will be described in detail.

The inner side surface of the outer side plate portion 21 surrounds and connects the outer side surface of the inner side plate portion 11 when the inner module 10 is detachably housed inside the outer module 20 in the vertical direction.

At this time, the outer side surface of the inner side plate portion 11 is inclined at a predetermined angle A with respect to the vertical line, and the inner side surface of the outer side plate portion 21 is formed with a Is inclined at one angle (B) and is inclined at a second angle (C) from the set point of the outer module (20) to the bottom of the outer module (20).

Here, preferably, the second angle may be formed larger than the first angle.

The angle A of the outer circumferential surface of the inner side plate portion 11 and the first angle B of the outer side plate portion 21 are formed to be equal to each other. 11) and the inner side surface of the outer side plate portion 21 are at least partly in line contact or surface contact ('X' portion), and the upper portion of the inner side plate portion 11 is connected to the upper side of the outer side plate portion 21 Can be supported.

In this case, the angle between the outer surface of the inner side plate portion 11 and the inner side surface of the outer side plate portion 21 is '0'. The load or pressure applied to the inner module 10 during the juicing of the juice due to the rotation of the screw 300 is transferred to the outer module 20 to enhance the rigidity of the inner module 10 have.

When the inner side surface of the outer side plate portion 21 is set in advance The angle? Formed by the outer surface of the inner side plate portion 11 and the inner side surface of the outer side plate portion 21 is set to be smaller than the first angle from the predetermined point to the bottom surface of the outer side plate portion 21, 0 '.

Thus, a space b is formed in which the outer side surface of the inner side plate portion 11 and the inner side surface of the outer side plate portion 21 are spaced apart from each other (refer to 'Y' portion). Here, the spacing space (b) serves as a channel through which the juice escaping through the gap (a) moves as described above.

Since the angle? Formed by the outer side surface of the inner side plate portion 11 and the inner side surface of the outer side plate portion 21 is larger than '0', the spacing space b can be further widened toward the lower side. By forming the spacing space b, a space can be secured in which the juice can be discharged through the gap a and flow.

Preferably, the inner side plate 11 is formed in a cylindrical shape whose diameter decreases toward the lower side, so that the spacing space b can be wider as it goes downward.

Alternatively, a step may be formed on the lower side of the inner side plate 11 so that the spacing b may be further widened toward the lower side by the step.

The juice that has passed through the spacing space b is discharged to the outside of the outer module 20 through the juice discharge hole 23 and the debris is discharged from the inner module 10 10, respectively.

Next, a drum housing of a juicer according to an embodiment of the present invention will be described.

Fig. 13 is a plan view of the drum housing of Fig. 1, Fig. 14 is a partial cutaway perspective view of Fig. 13, and Fig. 15 is a plan view of the drum housing and the outer module of Fig.

Referring to FIGS. 1 and 13 to 15, the drum housing 200 is formed in a cylindrical shape having an open upper surface and an internal space, and is mounted on the upper portion of the main body 10. The juice drum 400 and the screw 300 described above are disposed in the inner space, and the hopper 100 may be coupled to the opened upper surface.

A drum hole 260 is formed at the center of the bottom surface of the drum housing 200. The driving shaft 6 is inserted into the drum hole 260 and connected to the screw 300 so as to transmit power to the screw 300.

The inner circumferential surface of the drum hole 260 may have a shape corresponding to the shape of the drive shaft 6 so that the rotational force generated by the drive motor can be transmitted through the drive shaft.

That is, the drum housing 200 is mounted on the main body 1, and the power of a driving shaft (not shown) receiving the power of the driving motor (not shown) can be transmitted to the screw 300.

A waterproof portion 261 formed of an elastic material such as a packing may be provided around the drum hole 260. That is, a driving shaft for transmitting power to the screw 300 is inserted into the drum hole 260. The drainage of the juice or the juice juiced through the waterproof portion 261 can be prevented from leaking to the driving shaft side.

On the other hand, a juice outlet 220 is formed on a lower side of the drum housing 200, and a debris outlet 230 is formed on the other side.

The juice outlet 220 is formed to protrude in a pipe shape from one side of the drum housing 200 so that the juice can be easily discharged, and the debris can be discharged directly to the lower chamber.

At this time, the juice outlet 220 can be opened or closed by the juice opening / closing mechanism 240, and the juice outlet 230 can be opened or closed by the residue opening / closing mechanism 250.

On the bottom surface of the drum housing 200, a debris discharge groove 298 and a juice discharge groove 297 are formed around the drum hole 260.

The residue discharge groove 298 is formed on the bottom surface of the drum housing 200 in the circumferential direction on the outer side in the radial direction around the drum hole 260.

And the juice discharge groove 297 is formed along a circumference of the bottom surface of the drum housing 200, such as the waste discharge groove 298 can be formed in the outer radial direction from the debris discharge flute 298.

That is, the debris discharge groove 298 is located radially inward of the outer module 20, and the juice discharge groove 297 is located radially outward of the outer module 20.

A juice discharge connection groove 221 for interconnecting the juice discharge groove 297 and the juice discharge port 220 is formed and a debris discharge connection groove 227 for interconnecting the residue discharge groove 298 and the debris discharge port 230 231 are formed.

At this time, a blocking portion 232 for blocking the juice discharge groove 297 and the residue discharge groove 298 from each other is formed, so that juice and debris can be completely separated and discharged through different discharge openings.

A plurality of engaging bosses 299 may be formed along the circumferential direction between the residue discharge groove 298 and the juice discharge groove 297. In the present invention, a recessed shape is shown.

The coupling protrusion 19 of the inner module 10 protruding downward from the coupling groove 29 of the outer module 20 can be inserted into the coupling boss 299. [

The coupling boss 299 can be fixed together with the coupling protrusion 19 of the inner module 10 and the coupling groove 29 of the outer module 20 so that the inner module 10, And the drum housing 200 can be integrally combined. As a result, breakage of the inner module 10 and the outer module 20 is prevented, and the gap a and the spacing b described above can be maintained even when the screw 300 is rotated.

Next, an operation state of the juice extractor according to an embodiment of the present invention will be described. 16 to 19 are operational states of the juicer according to an embodiment of the present invention.

First, the juice discharge will be described. 17, when the juice material is injected into the hopper 100, the screw 300 is rotated, and the material is conveyed down while being conveyed. Then, during the process as shown in FIG. 18, the slit 12 of the inner module 10 And the ribs 22 of the outer module 20, as shown in Fig.

17, the juice discharged from the gap a between the slit 12 and the rib 22 passes through the spacing space b formed between the inner module 10 and the outer module 20 And is discharged to the space between the inner circumferential surface of the drum housing 200 and the outer surface of the outer module 20 through the juice discharge hole 23 of the outer module 20.

The discharged juice between the inner circumferential surface of the drum housing 200 and the outer circumferential surface of the outer module 20 moves downward into the juice discharge groove 297 formed in the bottom of the drum housing 200, And is discharged through the juice outlet 220 after passing through the juice outlet connecting groove 221 connected to the groove 297.

19, the debris squeezed between the screw 300 and the inner module 10 flows into the debris discharge groove 298. After passing through the debris discharge connection groove 231, (See arrows in Fig. 18).

At this time, the debris can not be directly transferred to the lower side of the inner module 10 by the outer flange 27 extending radially inward at the lower end of the inner module 10, and the debris is temporarily transferred to the upper surface of the outer flange 27 I will stay.

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.

Next, a first modified example of the juice drum of the present invention will be described. 20 is an assembled perspective view of the juice drum according to the first modification of the first modification.

20, no spacing space may be formed between the outer surface of the inner side plate 11 of the inner module 10 and the inner surface of the outer side plate 21 of the outer module 20.

In this modified example, the support portion 130 is formed to protrude in the radial direction on the inner side surface of the outer side plate portion 21.

When the inner module 10 and the outer module 20 are coupled to each other, the support portion 130 is brought into close contact with the outer surface of the inner plate portion 11.

Therefore, even if the juice drum 400 is vibrated during the juicing process, the support portion 130 elastically supports the inner plate portion 11 and the outer plate portion 21 while being in close contact with each other, so that the inner plate portion 11 and the outer plate portion 21 and the size of the spacing a and the spacing b can be kept constant.

Meanwhile, although not shown, the support portions 130 may be separated into at least two portions in a mutually engageable form (for example, a concave portion and a convex portion are mutually coupled).

At this time, a part of the separated supporting portions 130 may be formed on the inner side surface of the outer side plate portion 21 and the other portion may be formed on the outer side surface of the inner side plate portion 11.

That is, when the inner plate 11 and the outer plate 21 are integrally formed, the elastic support of the juice drum 400 against vibrations can be improved.

The formation position of the first rib jaw 13 according to the third modification is formed so as to abut the widthwise end of the slit 12 or adjacent to the slit 12. [ The bar shown is formed to abut the widthwise end of the slit 12.

When the first rib jaw 13 is formed adjacent to the slit 12, the debris can be less likely to be caught in a gap, which will be described later, than when the first rib jaw 13 is formed in the central portion of the inner plate portion 11 .

That is, when the first rib jaw 13 is formed adjacent to the slit 12, the pressing force applied to the gap in the process of the juice passing over the first rib jaw 13 is reduced, and the debris is caught in the gap Can be reduced.

In the longitudinal edge of the inner side plate 11 located at the upstream side with respect to the rotational direction of the screw 300 among the longitudinal edges of the slit 12 forming the slit 12, 18 may be formed.

The first rib jaw 13 is formed on the upstream side edge of the slit 12 and the sloped surface 18 is formed on the downstream side edge of the slit 12 as shown in FIG.

At this time, when the juice to be squeezed between the screw 300 and the inner module 10 is small enough not to overtake the first rib jaw 13, the debris flows along the first rib jaw 13, Moves to the lower side of the module (10).

When the amount of the residue increases and becomes larger than the first rib jaw 13, the residue rides over the first rib jaw 13 and is transferred to the adjacent first rib jaw 13 by the rotational force of the screw 300. At this time, .

The debris moves to the adjacent first rib jaw 13 through the gap a between the slit 12 and the rib 22 by the height of the first rib jaw 13. [ When the residue rides over the first rib jaw 13, the residue moves along the inclined surface 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 a between the slit 12 and the rib 22.

And the debris that strikes the adjacent first rib jaw 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 (a) formed between the slit 12 and the projection 22 in the process of moving the juice over the first rib jaw 13 is reduced, so that the trapping of debris in the gap can be minimized .
