In addition, the first rib jaw 13 may protrude from the inner circumferential surface of the inner plate portion 11 . In this embodiment, the first rib 13 is formed in a protruding band shape, but it can be deformed into any shape that comes into contact with the screw helix.

The material of the first rib 13 may be compressed or pulverized by interaction with the screw helix 310 according to the rotation of the screw 300 .

If there is no first rib jaw 13, the juice target may not go down and stagnate, or the compression force or crushing force may be low or not generated.

The first rib chin 13 may protrude inward in the radial direction from a corner formed in the vertical direction of the first slit 12 .

If the first rib 13 is formed in the middle part of the inside of the inner plate part 11, the material is finely cut in the middle part of the inner plate part 11 by the first rib 13 and the screw 300. As the particle size of the juice target is rapidly reduced by grinding, the juice target is rotated together with the screw helix 310 of the screw 300 without being caught on the second rib 14 at the bottom of the inner plate portion 11.

Therefore, the juice target is not smoothly transported downward along the screw helix 310 of the screw 300, and there is a problem of being stagnant inside the inner plate portion 11.

When the juice target is stagnant inside the inner plate 11, the additionally added juice target further increases the stagnation of the juice target, and the inconvenience of forcibly pressing the juice target using a separate tool causes inconvenience do.

In order to prevent such a problem from occurring, the first rib 13 according to the embodiment of the present invention is formed on the lower part of the inner plate 11, so that the size of the particles to be juiced does not change rapidly and gradually. As a result, the juice target is smoothly transported downward by the screw helix 310 and the second rib 14, and the juice target is moved downward by the first rib 13 at the bottom of the inner plate 11. It can be pulverized more finely.

As it is, the pressure due to the juice target residue of the inner plate portion 11 and the screw 300 gradually increases. The juice extracted from the juice target 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 .

In addition, while being transported to the lower portion, the primarily crushed juice target is further finely pulverized by the first rib 13 formed at the bottom of the inner plate portion 11, and increases between the screw 300 and the inner plate portion 11. The residue of the juice target is strongly pressed by the pressure, and the juice generated at this time is pushed upward, and the juice is discharged through the gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 Therefore, the juice extraction efficiency increases.

Accordingly, a gap is formed when the inner module 10 and the outer module 20 are coupled, and the gap is gradually formed outward in the radial direction so that the juice can be smoothly discharged. In addition, the cross section of the inner plate portion 11 may be semicircular or trapezoidal.

Through this, when the user places the outer module 20 inside the drum housing 200, the support groove 210 can be easily identified with the user's naked eyes, improving assembly quality.

In addition, if the support protrusion 26 is seated in the support groove 210, the outer module 20 can be fixed, and assembling properties can be remarkably improved.

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

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 protrusion 25 .

That is, the coupling position, rotation, and tilting of the inner module 10 and the outer module 20 are limited by the combination of the key groove 15 and the key protrusion 25, and at the same time, the size of the gap can be maintained. .

In addition, an annular outer flange 27 may be formed on the lower side of the outer plate portion 21 . The outer flange 27 does not directly move the debris to the lower side of the inner module 10, and the debris temporarily stays on the upper surface of the outer flange 27.

That is, the staying time of the juice target between the screw 200 and the inner module 10 increases, and as a result, the juice target can be sufficiently squeezed, and the juice extraction efficiency can be increased.

In addition, on the other hand, one side of the outer flange 27 is formed with a coupling groove 29 through which the coupling protrusion 19 of the inner module 10 passes.

When the coupling groove 29 and the coupling protrusion 19 are coupled, the relative position of the outer module 20 with respect to the inner module 10 is determined, and accordingly, the size of the gap can be maintained.

In the above-described coupling protrusion 19 and coupling groove 29, the projection can be transformed into a groove, the groove can be transformed into a projection, and the means for fixing the inner module 10 and the outer module 20 is from above. It is not limited to the coupling grooves and coupling protrusions described.

In addition, a hooking end 211 is formed on the lower side of the outer flange 27 . Therefore, when the outer module 20 surrounds the inner module 10 and is coupled, the hooking jaw 111 of the inner module 10 is seated on the hooking end 211 so that the outer module 10 is attached to the inner module 10. ) to support the bottom of the

Next, the gap formed by coupling the inner module and the outer module described above will be described.

7 is a coupling state diagram of FIG. 5, and FIG. 8 is a coupling state diagram of FIG. Referring to FIGS. 7 and 10 , when the inner module 10 is accommodated inside the outer module 20, the outer module 20 may be coupled while surrounding the inner module 10.

At this time, a rib 22 protruding from the inner surface of the outer plate part 21 is inserted into the slit 12 between the inner plate parts 11 to form a predetermined gap a. Here, the size of the gap (a) may be constant or not constant. In addition, the gap (a) may be formed to communicate with a separation space (b) to be described later.

The gap (a) is formed to be widened outward in the radial direction, so that the juice can be smoothly discharged.

In addition, the gap (a) may be formed such that the upper gap (a1) is larger than the lower gap (a2) in the longitudinal direction and becomes narrower from the upper side to the lower side. That is, since more pressure is applied to the lower side of the juice drum 400 during the compression process, it is preferable that the gap on the lower side of the juice drum 400 is narrowed.

For example, when the width of the slit 12 between the upper side of the inner plate portion 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 gap The size may be wider toward the upper side based on the stepped portion 24 .

In the case of hard juice objects such as carrots, juice may be discharged through a gap formed on the lower side during the pressing process. In the case of a soft juice object such as a tomato, the juice can be discharged as the juice accumulated in the gap formed on the lower side as well as the gap formed on the lower side rises to the wide gap on the upper side during the pressing process. In this way, when the size of the gap (a) is not constant, it is possible to improve juice extraction efficiency for both hard juice objects such as carrots and soft juice objects such as tomatoes.

The size of the gap (a) may be maintained constant without being changed during the juice extraction process. In addition, in the case of hard juice targets such as carrots, they may be accumulated in the gap (a) during the juice extraction process. In this case, since the juice target is caught by the stepped portion 24, accumulation of the juice target in the gap (a) can be prevented.

Next, the separation space (b) formed by the combination of the inner module 10 and the outer module 20 will be described.

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

Here, the separation space (b) serves as a passage through which the juice discharged through the gap (a) can move.

At this time, at least a part of the outer plate portion 21 and the inner plate portion 11 are in line contact or surface contact from the top downward to a certain point, and a separation space (b) may be formed from a certain point. The part where the at least part is in line contact or surface contact may form a space where the juice moves, such as the above-mentioned gap (a).

In addition, the separation space (b) may be formed to be wider or the same as it goes to the lower side.

11 is a longitudinal cross-sectional view of a coupled state of the screw and the juice module, and FIG. 12 is a partially enlarged view of FIG. 11 . 11 and 12, the separation space will be described in detail.

When the inner module 10 is detachably accommodated inside the outer module 20 in the vertical direction and coupled, the inner surface of the outer plate 21 surrounds the outer surface of the inner plate 11 and is coupled.

At this time, the outer surface of the inner plate part 11 is formed to be inclined at a certain angle (A) based on the vertical line, and the inner surface of the outer plate part 21 is divided up to a point set at the top of the outer plate part 21 based on the vertical line. It is inclined at 1 angle (B), and is formed to be inclined at a second angle (C) from a 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.

On the other hand, the angle (A) of the outer peripheral surface of the inner plate portion 11 and the first angle (B) of the outer plate portion 21 are formed identically, and the inner plate portion ( At least a part of the outer surface of 11) and the inner surface of the outer plate 21 are in line contact or surface contact ('X' marked portion) with each other, so that the upper part of the inner plate part 11 is formed by the upper part of the outer plate part 21. can be supported

In this case, the angle between the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 becomes '0'. Due to this, the load or pressure applied to the inner module 10 is transmitted to the outer module 20 during juice extraction of the juice target according to the rotation of the screw 300, so that the stiffness of the inner module 10 is reinforced. there is.

And the inner surface of the outer plate portion 21 is set in advance Since a second angle greater than the first angle is formed from a certain point to the bottom surface of the outer plate portion 21, the angle α formed by the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 is ' greater than 0'.

Thus, a separation space (b) in which the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 are spaced apart from each other is formed (see 'Y' mark). Here, the separation space (b) serves as a flow path through which the juice escaped through the gap (a) moves as described above.

As such, since the angle α formed between the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 is greater than '0', the separation space (b) may become wider toward the lower side. By forming the separation space (b), a space in which juice can be discharged and flowed through the gap (a) can be secured.

Preferably, the inner plate portion 11 is formed in a cylindrical shape whose diameter decreases toward the lower side, so that the separation space b may become wider toward the lower side.

Alternatively, a step difference may be formed on the lower side of the inner plate portion 11 so that the separation space b may become wider toward the lower side by the step difference.

As described above, the juice that has passed through the separation space (b) is discharged to the outside of the outer module 20 through the juice discharge hole 23, and the residue between the screw 300 and the inner module 10 is discharged to the inner module ( 10) can be discharged to the lower side.

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

13 is a plan view of the drum housing of FIG. 1, FIG. 14 is a partially cut-away perspective view of FIG. 13, and FIG. 15 is a plan view of the drum housing of FIG. 13 and an external module coupled thereto.

Referring to FIGS. 1 and 13 to 15 , the drum housing 200 has a substantially cylindrical shape with an open upper surface and an inner space, and is configured to be seated on the upper portion of the body part 1 . The juice drum 400 and the screw 300 described above may be disposed in the inner space, and the hopper 100 may be coupled to the open 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, and may 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 driving shaft 6 so that rotational force generated by the driving motor can be transmitted through the driving shaft.

That is, the drum housing 200 is seated on the main body 1 so that power of a driving shaft (not shown) receiving power from a driving motor (not shown) may be transmitted to the screw 300 .

A waterproof part 261 formed of an elastic material such as packing may be provided around the drum hole 260 . That is, a driving shaft that transmits power to the screw 300 is inserted into the drum hole 260, and leaking of juiced residue or juice to the drive shaft side through the waterproof portion 261 can be prevented.

Meanwhile, a juice outlet 220 is formed on one side of the lower part of the drum housing 200, and a dregs outlet 230 is formed on the other side.

The juice outlet 220 protrudes from one side of the drum housing 200 in a pipe shape so that the juice can be easily discharged, and the waste can be discharged directly downward.

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

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

The dregs discharge groove 298 is formed radially outside the drum hole 260 on the bottom surface of the drum housing 200 in a circumferential direction.

Also, the juice discharge groove 297 is formed in the circumferential direction on the bottom surface of the drum housing 200 like the waste discharge groove 298, and may be formed radially outside the waste discharge groove 298.

That is, the dregs discharge groove 298 is located inside the outer module 20 in the radial direction, and the juice discharge groove 297 is located outside the outer module 20 in the radial direction.

In addition, a juice discharge connection groove 221 interconnecting the juice discharge groove 297 and the juice outlet 220 is formed, and a residue discharge connection groove 221 interconnecting the residue discharge groove 298 and the residue discharge port 230 ( 231) is formed.

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

Meanwhile, a plurality of coupling bosses 299 may be formed between the waste discharge groove 298 and the juice discharge groove 297 along the circumferential direction. In the present invention, a recessed form is shown.

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

In this way, the coupling boss 299 is fixable 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 outer module 20 And the drum housing 200 may be integrally coupled. Through this, damage to the inner module 10 and the outer module 20 can be prevented and the above-described gap (a) and separation space (b) can be maintained despite the compression force caused by the rotation of the screw 300 .

Next, the operating state of the juicer according to an embodiment of the present invention described above will be described. 16 to 19 are operational state diagrams of a juicer according to an embodiment of the present invention.

First, juice discharge will be described. First, as shown in FIG. 17, when the juice material is put into the hopper 100, the screw 300 rotates and the material is compressed while being transported down, and then, as shown in FIG. 18, in the process, the slit 12 of the inner module 10 ) And the juice is discharged into the gap (a) between the rib 22 of the outer module (20).

Then, the juice discharged from the gap (a) between the slit 12 and the rib 22 passes through the separation space (b) formed between the inner module 10 and the outer module 20 as shown in FIG. , The juice is discharged between the inner circumference of the drum housing 200 and the outer surface of the outer module 20 through the discharge hole 23 of the outer module 20 .

Subsequently, the juice discharged between the inner circumferential surface of the drum housing 200 and the outer surface of the outer module 20 moves downward and flows into the juice discharge groove 297 formed on the bottom of the drum housing 200, and then the juice is discharged After passing through the juice discharge connection groove 221 connected to the groove 297, the juice is discharged through the outlet 220.

In the next waste discharge, referring to FIG. 19 , the waste compressed between the screw 300 and the inner module 10 flows into the waste discharge groove 298, passes through the waste discharge connection groove 231, and then the waste discharge port. It exits through 230 (see arrow in FIG. 18).

At this time, due to the outer flange 27 extending radially inward from the lower end of the inner module 10, the debris does not directly move to the lower side of the inner module 10, and the debris is temporarily placed on the upper surface of the outer flange 27. will stay

That is, the time the juice target stays between the screw 200 and the inner module 10 increases, and as a result, the juice target can be sufficiently squeezed, resulting in increased juice extraction efficiency.

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

Referring to FIG. 20 , a separation space may not be formed between an outer surface of the inner plate portion 11 of the inner module 10 and an inner surface of the outer plate portion 21 of the outer module 20 .

In this way, when the outer circumferential surface of the inner plate 11 and the inner circumferential surface of the outer plate 21 are in close contact, even if vibration is applied to the entire juice drum 400 during the juice extraction process, the inner module 10 and the outer module 20 are in close contact. It can be effective to keep the size of the gap (a) constant.

Next, a second modified example of the juice drum of the present invention will be described. 21 is a perspective view of an outer module according to a second modification, and FIG. 22 is a combined perspective view of a juice drum according to a second modification.

At least one of the inner surface of the outer plate 21 or the outer surface of the inner plate 11 has a support 130 for supporting the inner surface of the outer plate 21 and the outer surface of the inner plate 11 in close contact with each other may be intervened.

In this modification, it is shown that the support part 130 protrudes from the inner surface of the outer plate part 21 in the radial direction.

When the inner module 10 and the outer module 20 are coupled, the support part 130 comes into close contact with the outer surface of the inner plate part 11 .

Therefore, even if vibration is applied to the juice drum 400 during the juice extraction process, the support 130 elastically supports the inner plate 11 and the outer plate 21 while keeping them in close contact with each other, so that the inner plate 11 and the outer plate ( 21) can be effective in keeping the size of the gap (a) and the separation space (b) constant.

On the other hand, although not shown, the support part 130 may be formed separately into at least two parts in a mutually fastenable form (eg, a form in which a concave part and a convex part are mutually coupled).

At this time, some of the separated support parts 130 may be formed on the inner surface of the outer plate part 21, and other parts may be formed on the outer surface of the inner plate part 11.

That is, when formed in a mutually fastened form, the inner plate portion 11 and the outer plate portion 21 are integrally formed, so that the elastic support for vibration applied to the juice drum 400 can be improved.

Next, a third modified example of the juice drum of the present invention will be described. 23 is a perspective view of an inner module according to a third modification, and FIG. 24 is an operating state diagram of a juice drum according to a third modification.

Referring to FIG. 23, in the inner module 10 according to the third modified example, the formation position of the first rib 13 formed on the inner surface of the inner plate 11 is changed, and an inclined surface 18 is further added. do.

The formation position of the first rib jaw 13 according to the third modified example is formed so as to come into contact with the end of the slit 12 in the width direction or formed adjacent to the slit 12 . The bar shown is formed so as to come into contact with the end of the slit 12 in the width direction.

When the first rib 13 is formed adjacent to the slit 12, it is possible to reduce debris from being caught in the gap, which will be described later, compared to the case where the first rib 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 compression force applied to the gap decreases in the process of the juice target passing over the first rib jaw 13, thereby preventing debris from getting stuck in the gap. can be reduced

In addition, among the longitudinal edges forming the slit 12 on the inner surface of the inner plate portion 11, the longitudinal edge located upstream with respect to the rotational direction of the screw 300 has an inclined surface to prevent debris from getting caught in the gap ( 18) can be formed.

Expressing this differently around the slit 12, the first rib 13 is formed at the upstream edge of the slit 12, and the inclined surface 18 is formed at the downstream edge of the slit 12.

The rib 22 of the outer module 20 is inserted into the slit 12, and a gap a is formed between the slit 12 and the rib 22 to discharge the crushed juice. At this time, the residue of the juice target may be caught in the gap (a). However, by the first rib 13 and the inclined surface 18, it is possible to prevent the dregs of the juice extraction target from being caught in the gap a.

If this is explained in detail with reference to FIG. 24, When the screw 300 rotates inside the inner module 10, the juice target moves downward, which is a space in which the distance between the screw helix 310 and the inner plate 11 gradually decreases.

At this time, if the residue of the juice target crushed between the screw 300 and the inner module 10 is small enough to not pass over the first rib chin 13, the residue is inside along the first rib chin 13 Move to the lower side of the module (10).

At this time, when the amount of scum increases to the extent that it rides over the first rib chin 13, the scum climbs over the first rib chin 13 and moves to the adjacent first rib 13 by the rotational force of the screw 300. go to

And, by the height of the first rib rib 13, the scum crosses the gap a between the slit 12 and the rib 22 and moves to the adjacent first rib 13. When the debris rides over the first rib jaw 13, the debris moves to the adjacent first rib jaw 13 along the inclined surface 18 formed at the edge of the slit 12 facing the first rib jaw 13. Therefore, debris is prevented from being caught in the gap (a) between the slit 12 and the rib 22.

In addition, the debris colliding with the adjacent first rib 13 moves to the lower side of the inner module 10 along the adjacent first rib 13.

In addition, the compression force applied to the gap (a) formed between the slit 12 and the protrusion 22 is reduced in the process of the juice extraction target crossing the first rib 13, thereby minimizing the trapping of debris in the gap. .

Next, a fourth modified example of the juice drum of the present invention will be described. 25 is a perspective view of an outer module according to a fourth modification, and FIG. 26 is a bottom perspective view of a juice drum coupled according to a fourth modification.

And, the outer surface 21 is formed with a stepped portion 28 protruding outward in the radial direction. At this time, the step portion 28 is Formed with a step difference with the outer flange 27 is shown.

Also, the juice discharge hole 23 may be formed on a bottom surface protruding outward in a radial direction from the stepped portion 28 .

Through this structure, the juice discharged from the upper part of the gap (a) may be discharged to the outer lower portion of the outer module 20 through the juice discharge hole 140 .

At this time, since the outer surface of the outer module 20 is composed of a continuously blocked surface, splashing of juice to the inner surface of the drum housing 200 can be prevented.

Next, a fifth modified example of the juice drum of the present invention will be described. 27 is a perspective view of an outer module according to a fifth modified example, and FIG. 28 is a bottom perspective view of FIG. 27 .

27 and 28, in the juice module 400 according to the fifth modified example, the lower protrusion 21a extending the outer plate portion 21 to the lower side of the outer flange 27 of the outer module 20 In the inner module 10, the inner plate portion 11 extends to a length corresponding to the lower protrusion 21a.
