Description

Juicer {JUICER}

The present invention relates to a juicer, and more particularly, to a juicer screw used in a juicer to produce juice juice by pressing and crushing vegetables or fruits, and a juicer using the same.

For health, green juice or juice is often made and eaten at home, and for this purpose, a number of devices have been disclosed that allow the juice to be extracted simply by using vegetables or fruits at home.

Conventionally, the juicer puts the material in the inlet and crushed it by a blade rotating at a high speed to make juice by centrifugation. However, such juicers may destroy the taste and nutrients inherent in ingredients during high-speed crushing, and it was difficult to make green juice with vegetables made of stems or leaves, and it was difficult to make juice with fruits such as kiwi or strawberry with high viscosity. No, it was impossible at all to make soy milk from soybeans.

In order to solve this problem, Korean Patent Registration No. 10-0793852 is a method of compressing and crushing material between a mandrel and a screw rotating at a low speed, and using the principle of grinding and pressing beans into soy milk. There is an effect of making juice by grinding and pressing fruits with high viscosity, such as tomatoes, kiwis, and strawberries, on a steel plate, so that the problem of the conventional juicer as described above could be solved.

However, even in this case, due to the size of the screw and the size of the input port that is manufactured so that the material of an appropriate size is injected according to the size of the screw, there is an inconvenience of having to cut the material in advance before putting the material into the input port.

Accordingly, Korean Patent Registration No. 10-1270140 increases the size of the inlet port and pre-crushes the large material by the crushing part and the crushing part to supply the crushed material to the eccentric side of the screw. Larger ingredients can be juiced without increasing their size.

However, even in this case, since the structure of the conventional juicer that fixedly supports the upper and lower ends of the screw rotation shaft, the inlet port for inputting the large material is in a shape that protrudes outward from an eccentric position to one side of the screw. As a result, there was a problem that the shape of the juicer became large and complicated, and furthermore, the configuration of crushing the material before juice, such as the crushed part and the crushed part, became complicated.

In addition, when debris accumulates on the lower surface of the screw during the juice process, a strong pressure is generated to move the screw in the vertical upward direction. When the screw moves upward, the durability of the juicer decreases due to vibration, and further, the separation distance between the net drum and the screw is changed, so that the juice efficiency may drop rapidly. In particular, in a structure in which the upper and lower ends of the screw are not fixedly supported but only the lower end is supported as in the present invention, a structure to prevent the screw from rising is required.

Hereinafter, the present design will be described with reference to the drawings for explaining a juicer according to embodiments of the present invention.

1 is a cross-sectional view of a juicer according to an embodiment of the present invention.

The juicer according to an embodiment of the present invention may be configured to include a main body 100, a housing 200, a screw 300, and a juice drum 400.

The main body 100 is supported from the bottom surface and a driving unit 110 for rotating the screw 300 may be disposed therein. The driving unit 110 may be composed of a motor and a reducer, but may be composed of only a low-speed motor without a reducer. Unlike the conventional blender that finely crushes the material by rotating the rotating blade at high speed, in the present invention, the juicer and the juicer to perform juice by separating the juice and the debris by rotating the screw 300 at a low speed to compress and crush the material Since it is related, the screw 300 is rotated at a low speed.

At this time, the drive shaft 120 of the motor protrudes from the top of the main body 100, the drive shaft 120 is coupled to the screw 300 to rotate the screw 300.

The housing 200 has an overall shape of a container and is attached to an upper portion of the main body 100, and may accommodate a screw 300 and a juice drum 400 to be described later. The housing 200 may be formed in a form in which the upper surface of the housing 200 is entirely open, and material may be introduced into the housing 200 through an inlet 230 which is an open upper surface. Accordingly, as shown, a material having a size larger than the radius of the screw 300 may also be introduced into the housing 200. Although not shown, a lid (not shown) for opening and closing the upper inlet 230 of the housing 200 may be formed. A separate injection hole may be formed in the lid to limit the size of the material injected into the housing 200 to be larger than the radius of the screw 300 but within a predetermined range.

In the center of the bottom of the housing 200, a waterproof cylinder 240 having a through hole 242 is formed to protrude upward, and a lower rotation shaft 350 of the screw 300 to be described later is inserted through the through hole 242 It may be coupled to the drive shaft 120 under the housing 200. The waterproof cylinder 240 is formed to protrude upward to prevent juice from flowing into the driving unit 110 through the through hole 242. In addition, a packing ring (not shown) formed of a material such as rubber or silicone is inserted at the edge of the through hole 242 to more effectively prevent the juice from flowing into the body 100.

A screw 300 is disposed at the lower end of the housing 200, and as shown, the upper inner side of the housing 200 located above the screw 300 waits before the material input from the inlet 230 is juiced. To form an atmospheric space.

In addition, a juice outlet 250 for discharging the juice juiced from the material inside the housing 200 and a waste outlet (not shown) for discharging the remaining waste are formed to be spaced apart from the lower end of the housing 200.

As described later, the juice flowing out of the juice drum 400 through the outlet hole of the juice drum 400 flows to the juice outlet 250 communicating with the bottom of the housing 200 and is discharged, and separated by juice. The remaining waste may be discharged to the outside of the juice drum 400 through the bottom or one lower side of the juice drum 400 and finally discharged from the waste outlet of the housing 200 in communication therewith.

The screw 300 is disposed at the lower end of the housing 200, the shaft hole 351 of the lower rotation shaft 350 extending downward from the inner center of the screw 300 to the drive shaft 120 of the above-described body 100 By inserting into the screw 300 can be mounted.

In the present embodiment, the housing 200 has the screw 300 disposed therein, and the juice outlet 250 and the waste outlet are attached to the lower housing 210 and the lower housing 210 formed outside the lower end. It may be formed separated by an upper housing 220 that forms a space in which the material inputted from the open inlet 230 stays.

At this time, a pressing step 222 or a pressing protrusion 224 is formed at the lower end of the upper housing 220 as shown, and the juice is disposed inside the lower housing 210 when it is fastened to the lower housing 210. The drum 400 is pressed down to fix the position of the juice drum 400. In FIG. 1, the pressing step 222 supports the upper edge side and the upper surface of the inner module 410 constituting the juice drum 400 and presses it downward, so that the pressing protrusion 224 protrudes downward to juice the juice. It is formed to press the upper edge of the outer module 450 constituting the drum 400 in a downward direction, but is not limited thereto and may be modified in various forms.

In addition, one or more crushing latches 270 protruding in the vertical direction may be formed on the inner side of the upper housing 220 along the circumferential direction of the inner side. As will be described later, the screw 300 according to the present invention may be formed in a shape in which the screw thread 320 extends above the screw body 310. At this time, the end of the screw thread 320 extending above the screw body 310 is located at the lower end of the upper housing 220. At this time, even if a material having a large size such as an apple or orange in a state that has not been cut in advance is introduced into the upper housing 220, the screw thread 320 extending over the screw body 310 rotates and the upper housing 220 The material can be effectively crushed by interaction with the crushing locking projection 270 protruding in the longitudinal direction along the inner surface. That is, the material can be crushed by pressing and mutual cutting according to rotation of the screw thread 320 extending above the screw body 310 in a state in which the material having a large size is caught by the crushing locking projection 270. At this time, when the screw 300 rotates, the pulverized materials can be easily moved under the screw 300 along the surface of the screw thread 320 inclined downward.

In the present embodiment, a case where the crushing protrusion 270 is formed on the upper housing 220 is described as an example when the housing 200 is separated into the upper housing 220 and the lower housing 210, As will be described later with reference to FIG. 41, the housing 200 may be integrally formed without being separated into the upper housing 220 and the lower housing 210. Also in this case, a crushing locking jaw 270 protruding in the longitudinal direction along the circumferential direction of the inner surface of the housing 200 may be formed, and the crushing locking jaw 270 may extend to the upper portion of the screw body 310. In order to interact with the screw thread 320, the lower end of the crushing locking jaw 270 is formed to extend to the upper end of the screw 300 where the screw thread 320 extending above the screw body 310 is located. desirable.

In this case, the direction of the crushing locking protrusion 270 is preferably formed to protrude vertically below the inner surface of the housing 200, but may be formed to be inclined at a predetermined angle. In addition, when the plurality of crushing locking projections 270 are formed along the inner surface of the housing 200, each inclination angle may be formed differently.

The screw 300 is disposed at the lower end of the housing 200 to receive power from the drive shaft 120 of the main body 100 and rotates at a low speed around the rotation axis, and between the juice drum 400 and the screw 300 to be described later. The located material is moved to the lower side, and the juice is pressed and pulverized by interaction with the juice drum 400 to perform juice.

A lower rotation shaft 350 protruding downward is formed under the screw 300, and as described above, the lower rotation shaft 350 is coupled to the drive shaft 120 of the motor to perform rotational motion. In this case, a shaft hole 351 into which the drive shaft 120 is inserted is formed in the lower rotation shaft 350, and the screw 300 may be coupled to the drive shaft 120. Preferably, it is formed as a square shaft hole 351 so that the coupling between the drive shaft 120 and the screw 300 can be firmly formed, and accordingly, the drive shaft 120 is preferably formed as a square shaft.

Hereinafter, various embodiments of the screw 300 according to the present invention will be described in more detail with reference to FIGS. 2 to 11.

2 and 3 are perspective views of the screw according to the first embodiment of the present invention shown in FIG. 1, FIG. 4 is a plan view of FIG. 2, and FIG. 5 is a side view of FIG. 2 taken from various angles, and FIG. 6 Is a perspective view of a screw according to a modified example of FIG. 2, FIG. 7 is a plan view of FIG. 6, FIG. 8 is a side view of FIG. 6 viewed from various angles, and FIG. 9 is a perspective view of a screw according to another modified example of FIG. And FIG. 10 is a plan view of FIG. 9, and FIG. 11 is a side view of FIG. 9 taken from various angles.

The screw 300 may be formed including a screw body 310 and a screw thread 320 protruding in a spiral shape on the outer surface of the screw body 310.

As shown, the screw body 310 may be divided into an upper portion and a lower portion centering on a portion having the largest radius of the screw 300 as shown. The lower portion of the screw body 310 is formed such that the radius gradually decreases as it goes downward, and the radius decreases as it goes downward, thereby forming a space in which the waste separated by juice is located. However, the lower shape of the screw body 310 is not limited thereto, and for example, it may be formed in a straight line downward without a change in radius.

In addition, the upper portion of the screw body 310 is formed so that the radius gradually decreases as it goes upward, and the width of the change in the radius according to the height change is larger than that of the lower portion of the screw body 310 as shown. The uppermost end of the screw body 310 is formed to have the smallest radius and gradually increase in radius as it goes downward.According to this shape, a material having a large size is gradually reduced in size by compression and pulverization and can be transferred. It forms a space. In other words, since the diameter of the upper portion of the screw body 310 gradually increases as it goes downward, the size of the space through which the material formed by the screw body 310 together with the screw thread 320 is transported gradually increases along the transport direction of the material. Becomes smaller. That is, the material is compressed and pulverized by the rotation of the screw 300 to gradually decrease in size and move under the screw 300 along the transfer space gradually decreasing along the screw thread 320 formed in the downward direction. It is done.

The screw thread 320 is formed protruding from the outer circumferential surface of the screw body 310 in the form of a spiral, by which the object of juice is compressed into a narrow gap between the screw 300 and the juice drum 400 by the screw thread 320 It is transferred to the lower side. At this time, the screw thread 320 is preferably protruded to contact or close to the juice drum 400 or the housing 200. As described above, since the upper portion of the screw body 310 has a smaller radius as it goes upward, the protruding height of the screw thread 320 is formed to increase toward the upper portion of the screw body 310.

Screw thread 320 may be formed in one or a plurality, in the present invention, any one thread is formed extending upward of the screw body 310 in the form of a spiral as shown (hereinafter,'the first screw thread ( 320-1) is called'extended part'). Therefore, since the screw body 310 does not exist at the height at which the extension of the first screw thread 320-1 is formed, the size is larger than the radius of the screw 300 even when considering the extension of the first screw thread 320-1. A space in which a large material is located can be formed, and when the screw 300 rotates in the space, the extension of the first screw thread 320-1 and the crushing locking protrusion 270 formed on the inner surface of the housing 200 ), the material can be crushed. At this time, since the surface of the screw thread 320 is formed to be inclined downward, the crushed material is transported downward along the screw thread 320 and juice is performed at the lower end of the screw 300.

As described above, in the present invention, it is not necessary to support the upper rotation shaft on the screw 300 by supporting only by the lower rotation shaft 350, away from the conventional structure for supporting and rotating both ends of the rotation shaft of the screw 300. Therefore, the entire space on the screw 300 can be utilized, and thus, a material having a large size can be directly injected through the inlet 230 on the screw 300 to perform juice. However, in this case, compared to the support structure at both ends of the screw rotation shaft, the screw can easily move upward during the pressing process, and the present invention proposes several embodiments for preventing the screw from moving upward. This will be described later with reference to FIGS. 15 to 40.

At this time, as shown in FIGS. 2 to 5, the shape of one end of the extension part of the first screw thread 320-1 is the opposite direction in which the first screw thread 320-1 extends above the screw body 310 It is formed in the shape of a concave arc, and as a whole, the first screw thread 320-1 at the top may have a hook shape.

In addition, as shown in FIGS. 6 to 8, one end of the extended portion of the first screw thread 320-1 is formed in a straight line, so that the first screw thread 320-1 at the upper end has a semicircular shape as a whole. There can be.

Further, as shown in FIGS. 9 to 11, the shape of one end of the extension part of the first screw thread 320-1 is in a direction in which the first screw thread 320-1 extends above the screw body 310. It is formed in the shape of a convex arc, and as a whole, the first screw thread 320-1 at the top may have a cotyledon shape.

In addition, as shown, a second screw thread 320-2 formed in a spiral shape starting from the top of the screw body 310 and downward may be formed, and the first screw thread of the lower part of the screw body 310 Another plurality of threads 320-3 may be formed between the second screw threads 320-1 and the second screw threads 320-2. Therefore, the width between the adjacent screw threads 320 formed in the screw body 310 is formed to have a relatively wide gap in the upper portion of the screw body 310, and a plurality of screws are formed in the lower portion of the screw body 310 It is formed to have a relatively narrow gap by the threads (320-1, 320-2, 320-3). That is, the upper side of the screw 300 mainly performs a function of crushing a large sized juiced object, and the lower side of the screw 300 may mainly perform a juice function by crushing and pressing.

In addition, a plurality of debris guide jaws 330 protruding outside the radius of the lower end of the screw body 310 may be formed in a circumferential direction. When the screw 300 rotates, the remnant guide 330 performs a function of sweeping the remnants separated by juice and transferred to the lower side of the juice drum 400 to the lower side. In this way, by the dregs guide 330 formed on the outer circumferential surface of the lower end of the screw 300, the dregs caught under the juice drum 400 may be smoothly removed, thereby further increasing the juice efficiency.

Again, referring to FIG. 1, when the juice drum 400 is described, the juice drum 400 is coupled to the housing 200 in the housing 200 and accommodates the screw 300 therein. That is, the juice drum 400 is located between the housing 200 and the screw 300. The material input from the inlet 230 and located on the upper part of the housing 200 crushes the material through the interaction of the first screw thread 320-1 and the crushing protrusion 270 and is transferred downward. Next, the material located between the juice drum 400 and the screw 300 is compressed and crushed while being transported down along the screw 300. The juice juiced in this process is discharged to the outside of the juice drum 400 through an outlet hole formed in the juice drum 400 and finally discharged through the juice outlet 250 of the housing 200, and the juice separated from the juice is It is transferred to the space under the juice drum 400 and finally discharged through the waste outlet of the housing 200.

Hereinafter, the juice drum 400 according to an embodiment of the present invention will be described in more detail with reference to FIGS. 12 to 14.

12 and 13 are exploded perspective views of the juice drum shown in FIG. 1, and FIG. 14 is a combined perspective view of the juice drum of FIGS. 12 and 13;

As shown, the juice drum 400 according to the present invention may be configured by a combination of the inner module 410 and the outer module 450. Here, the inner module 410 and the outer module 450 may be made of a material such as polyetherimide (PEI).

The inner module 410 may have a generally cylindrical shape and may have upper and lower sides open. Here, the inner module 410 includes a plurality of inner plate portions 411 and a plurality of slits 412 are formed by the plurality of inner plate portions 411.

Here, the plate portion is named for convenience for explanation of the design, and when it is divided into a hole portion in which the slit 412 is formed and a plate portion in which the slit 412 is not formed in the cylindrical module, the plate portion in which the slit 412 is not formed It is defined as "distributor."

In this case, the width of the slit 412 on the upper side of the slit 412 may be smaller than the width of the slit 412 on the lower side. That is, the width of the slit 412 may be narrower as it goes upward. In addition, as illustrated in FIG. 12, a step portion 413 may be formed in the slit 412. A width of the upper slit 412 may be smaller than the width of the lower slit 412 based on the stepped portion 413.

In addition, a first rib protrusion 420 may be formed on an inner circumferential surface of the inner plate portion 411. The first rib tuck 420 compresses or crushes the material by interaction with the screw thread 320 according to the rotation of the screw 300. If the first rib tuck 420 is not present, the juiced object may be stagnated without going down, or the pressing force or the crushing force may be low or may not occur.

In addition, a second rib protruding 425 may be formed on the inner surface of the inner plate portion 411 in the longitudinal direction. The second rib tuck 425 performs a function of transporting the material injected into the juice drum 400 to the lower portion and crushing the juice object. The second rib tuck 425 may perform a function of reinforcing the rigidity of the inner module 410 and may perform a function of guiding a juice object into the juice drum 400. In addition, the second rib tuck 425 may perform a function of adjusting the position of the screw 300 and adjusting the juice space.

The protruding height of the second rib chin 425 may be formed to have the same height from the top to the bottom of the inner module 410, but is preferably formed in a form that gradually decreases from the top to the bottom of the inner module 410 Can be. In addition, the second rib chin 425 is formed to incline downward from the top to the bottom of the inner module 410, and protrudes toward the screw 300 at an intermediate portion thereof to form a stepped step 426. I can. The stepped portion 426 may be variously modified in its position, number, or protruding height according to the shape of the screw 300 and the design condition of the screw thread 320. The number and arrangement form of the second rib tuck 425 may be variously changed as necessary in consideration of design conditions and efficiency of juice. In the embodiment of the present invention, the formation direction of the second rib tuck 425 has been described as an example that is formed vertically in the vertical direction of the inner module 410, but the scope of the present invention is not limited thereto.

In this case, the first rib jaw 420 is formed on the lower inner surface of the inner plate portion 411, and the second rib jaw 425 is formed entirely below the inner surface of the inner plate portion 411.

Next, the outer module 450 will be described. The outer module 450 is generally cylindrical and includes an outer plate portion 451 whose upper and lower sides are open and a rib 452 protruding from an inner surface of the outer plate portion 451.

The outer plate portion 451 is formed to be detachable (removable) by receiving the inner module 410 therein. That is, when the outer module 450 is coupled to the inner module 410, the outer module 450 may be coupled to receive and surround the inner module 410 inside. In this case, the outer module 450 may wrap and support the inner module 410.

When the outer module 450 and the inner module 410 move up and down and are coupled, the rib 452 is inserted into and coupled to the slit 412 under the slit 412 of the inner module 410. At this time, a slit hole, which is a fine gap formed between the slit 412 and the rib 452, is formed, and the juice generated in the juice drum 400 can be discharged to the outside through the slit hole.

As described above, in this embodiment, the inner module 410, the slit 412 and the outer module 450 of the rib 452 are combined to discharge the juice through the gap between the slit 412 and the rib 452 Because it forms, it is very easy to clean compared to the conventional mesh drum.

At this time, the rib 452 may be formed to correspond to the shape of the slit 412 described above, and the width of the rib 452 is narrower toward the upper side, so that the width of the upper rib 452 is It may be smaller than the width of the rib 452.

In addition, a step portion 453 is formed in the rib 452, so that the width of the upper rib 452 may be smaller than the width of the lower rib 452 based on the step portion 453.

When the outer module 450 and the inner module 410 are moved up and down by the shape of the rib 452 and the slit 412 as described above, when the outer module 450 and the inner module 410 are moved up and down, the width is relatively lower than the relatively large slit 412 By inserting the upper portion of the small rib 452, the outer module 450 and the inner module 410 can be easily coupled.

In addition, a plurality of juice discharge holes 460 may be formed in the outer plate portion 451 along the plate surface of the outer plate.

In this way, the juice formed in the juice drum 400 formed by the combination of the inner module 410 and the outer module 450 is the slit 412 of the inner module 410 and the rib 452 of the outer module 450 It may be discharged to the outside of the juice drum 400 by passing through the slit hole formed therebetween and the juice discharge hole 460 formed in the outer module 450.

At this time, it is preferable that the gap formed between the slit 412 and the rib 452 is formed so that the width of the gap increases in the radial direction to facilitate the discharge of juice. Further, the gap is made to have a smaller width of the gap as it goes downward in the longitudinal direction, so as to prevent the debris generated by being crushed more finely as it goes downwards to be discharged through the gap and to apply strong pressure by the screw 300 It is desirable to support it.

Hereinafter, a structure for preventing the screw from moving upward will be described with reference to FIGS. 15 to 40.

First, a description will be given of a structure for preventing screw upward movement according to a first embodiment of the present invention.

FIG. 15 is an exploded perspective view of a structure for preventing screw upward movement according to a first embodiment of the present invention, and FIG. 16 is a view showing a state in which a protrusion is inserted into an insertion part by rotation of a drive shaft to prevent the screw from moving upward, 17 is a diagram illustrating a modification example of FIGS. 15 to 16.

As shown in FIG. 15, a protrusion 1210 protruding in a radial direction is formed on a side surface of the driving shaft 120 protruding from the upper portion of the main body 100. In this case, the protrusion 1210 is preferably formed to protrude symmetrically on both sides of the drive shaft 120. The protrusion 1210 may be manufactured integrally with the driving shaft 120, or may be manufactured by forming a hole penetrating through the driving shaft 120 to force a pin into the hole. The position of the protrusion 1210 is located below a predetermined distance from the upper end of the drive shaft 120, and the upper end of the drive shaft 120 including the protrusion 1210 is inserted into the shaft hole 351 of the screw 300.

A lower rotation shaft 350 protruding downward from the inside is formed in the lower center of the screw 300. As described above, the lower rotation shaft 350 rotates the screw 300 by receiving power from the motor by being coupled with the drive shaft 120 of the motor.

A shaft hole 351 is formed from the lower end of the lower rotation shaft 350 to the inside, and the upper end of the driving shaft 120 is inserted into the shaft hole 351 to be coupled. In this embodiment, it is preferable that it is formed as a circular shaft hole 351, and accordingly, the drive shaft 120 may also be formed as a circular drive shaft 120 in cross section.

In addition, the upper and lower guide portions 3502 that are open from the lower end of the lower rotary shaft 350 to the upper are formed, and the lower rotary shaft 350 of the screw 300 is driven by linearly moving the screw 300 vertically downward. When fastened to, the upper and lower guide portions 3502 provide a path so that the protrusion 1210 can move up and down inside the rotation shaft without interference. When the protrusions 1210 are formed symmetrically on both sides of the drive shaft 120, the upper and lower guide portions 3502 are also symmetrically formed on both sides of the lower rotation shaft 350. The lower end of the upper and lower guide portions 3502 forms an inclined surface 3503 so that the open width gradually decreases toward the upper portion, so that the protrusion 1210 is guided along the inclined surface 3503 so that it can be easily inserted into the upper and lower guide portions 3502. There can be.

In this case, an insertion portion 3501 is formed which is opened in the circumferential direction from the upper end of the upper and lower guide portions 3502 and into which the protrusion 1210 is inserted. Therefore, when inserting the upper end of the drive shaft 120 into the shaft hole 351 to fasten the lower rotation shaft 350 of the screw 300 to the drive shaft 120, the protrusion 1210 is guided along the upper and lower guide parts 3502 As a result, it can be moved inside the lower rotating shaft 350 and positioned at the upper end of the upper and lower guide parts 3502. At this time, when the drive shaft 120 is rotated or the screw 300 is rotated, the protrusion 1210 may be inserted into the insertion unit 3501. When the drive shaft 120 is rotated during the juice process, the protrusion 1210 is inserted into the insertion part 3501 and the outer surface of the protrusion 1210 in the rotational direction and the inner surface of the insertion part 3501 come into contact with each other. The rotational force of 120 may be transmitted to the screw 300 through the contact. In addition, when the screw 300 receives an upward pressure due to an increase in internal pressure during the juice process, the lower outer surface of the protrusion 1210 and the lower inner surface of the insertion part 3501 come into contact to prevent the screw 300 from moving upward. I can do it.

In this embodiment, unlike a modification to be described later with reference to FIG. 17, since the protrusion 1210 is inserted into the insertion part 3501 in the form of being fitted, the protrusion 1210 even when the screw 300 receives a strong downward pressure. It is possible to prevent the downward movement of the screw 300 by contacting the upper outer surface of and the upper inner surface of the insertion part 3501.

In this case, the insertion portion 3501 may be formed on both left and right sides of the upper and lower guide portions 3502 as shown, or may be formed only on one side. When formed on both left and right sides, it is inserted into any one of the left and right insertion portions 3501 according to the rotation direction of the drive shaft 120 to transmit the rotational force of the drive shaft 120 and prevent the screw 300 from moving upward. I can do it.

The upper and lower guide parts 3502 and the insertion part 3501 may be formed to be completely open in the radial direction as shown, or a groove dug in the radial direction inside the shaft hole 351 of the lower rotation shaft 350 It may be formed in the form of.

The protective cap 3510 is formed in a ring shape having a ring surface, and is inserted into the outer circumferential surface of the lower rotation shaft 350 so that the ring surface of the protective cap 3510 covers the coupling part between the protrusion 1210 and the insertion part 3501 . The rigidity of the coupling portion between the lower rotation shaft 350 and the drive shaft 120 may be reinforced by the protective cap 3510. At this time, as shown, a stepped jaw 3505 may be formed on the insertion portion 3501, and the top surface of the protective cap 3510 contacts the stepped portion 3505 to determine the insertion position of the protective cap 3510 When the protective cap 3510 is inserted into the stepped jaw 3505, the outer peripheral surface formed by the lower rotation shaft 350 and the protective cap 3510 may be formed as a surface without a step.

17 shows a modified example of the structure for preventing the screw 300 from moving upward according to the first embodiment. In this embodiment, the upper and lower opening widths of the insertion portion 3501 are protruding portions compared to the first embodiment. It is characterized in that it is larger than the upper and lower widths of (1210). When fastening the lower rotation shaft 350 to the drive shaft 120, there is no need to move the screw 300 so that the protrusion 1210 is located at the upper end of the upper and lower guide parts 3502, and the protrusion 1210 is inserted into the insertion part 3501 ) Is formed at the upper end of the upper and lower guide portions 3502, the drive shaft 120 or the screw 300 is rotated so that the protrusion 1210 is positioned within the insertion portion 3501. At this time, as described above, when the driving shaft 120 rotates, the outer surface in the rotation direction of the protrusion 1210 and the inner surface of the insertion part 3501 come into contact, so that the rotational force of the driving shaft 120 is brought into contact with the screw ( 300). In addition, when the screw 300 receives an upward pressure due to an increase in internal pressure during the juice process, the lower outer surface of the protrusion 1210 and the lower inner surface of the insertion part 3501 come into contact to prevent the screw 300 from moving upward. I can do it.

In this embodiment, as the insertion portion 3501 is formed larger than the vertical width of the protrusion 1210 in the upward direction, the screw 300 may form a predetermined clearance in the vertical direction, or the upper end of the drive shaft 120 The surface and the upper surface of the shaft hole 351 may be formed to contact each other to prevent movement of the screw 300 downward.

Even in the modified example of FIG. 17, a protective cap 3510 may be formed to reinforce the bonding site.

Next, a structure for preventing the screw 300 from moving upward according to a second embodiment of the present invention will be described.

FIG. 18 is an exploded perspective view of a structure for preventing screw upward movement according to a second embodiment of the present invention, FIG. 19 is a cut-away perspective view showing the inside of the rotation shaft of the screw in FIG. 18, and FIG. 20 is a bottom view of the rotation shaft of the screw in FIG. 18 FIG. 21 is a side cross-sectional view showing a state in which the screw rotation shaft is coupled to the drive shaft to prevent the screw from moving upward, and FIG. 22 is a first of the present invention for explaining a modified example inside the rotation shaft in FIG. 2 is a separate cross-sectional view of the screw upward movement prevention structure according to the embodiment, FIG. 23 is a cross-sectional view showing a state in which the rotational shaft and the drive shaft of the screw are coupled in FIG. 22, and FIG. 24 is Fig. 25 is an exploded perspective view of the structure, and Fig. 25 is a side view (Fig. 25 (a) and (b)) and a plan view (Fig. 25 (c)) of the drive shaft in Fig. 24, and Fig. 26 is a bottom view of the rotation shaft of the screw in Fig. 24 FIG. 27 is a cross-sectional view taken along line A-A' in FIG. 24, and FIG. 28 is a cross-sectional view showing a state in which the drive shaft is coupled to the rotational shaft of the screw along line A-A' in FIG. 24 is a side cross-sectional view showing a state in which the screw rotation shaft is coupled to the drive shaft to prevent the screw from moving upward.

As shown in FIG. 18, a locking pin 1220 protruding in a radial direction is formed on a side surface of the driving shaft 120 protruding above the main body 100. At this time, it is preferable that the locking pin 1220 is formed to protrude symmetrically in both directions. The locking pin 1220 may be manufactured integrally with the driving shaft 120, or may be manufactured by forming a hole penetrating the driving shaft 120 to force the pin into the hole. The position of the locking pin 1220 is located below a predetermined distance from the upper end of the driving shaft 120, and the upper end of the driving shaft 120 including the locking pin 1220 is inserted into the shaft hole 351 of the screw 300. At this time, in this embodiment, the drive shaft 120 has a stepped step 1222 formed so as to reduce the diameter at the top, which will be described later. The locking pin 1220 is formed on the stepped jaw 1222.

A shaft hole 351 is formed from the lower end of the lower rotation shaft 350 to the inside, and the upper end of the driving shaft 120 is inserted into the shaft hole 351 to be coupled. At the lower end of the lower rotation shaft 350, a rising preventing part 3251 protruding from the inner surface of the shaft hole 351 in the form of a flange for a predetermined distance in the radial center direction may be formed. As will be described later, when the screw 300 is subjected to an upward pressure, the locking pin 1220 may contact the upper surface of the ascending prevention unit 3251 to prevent the screw 300 from moving upward.

At this time, as shown in Fig. 20, the anti-lift part 3251 is not continuously formed along the circumferential direction of the shaft hole 351, but a guide part 3523 open up and down in some spaces is formed, which is a drive shaft When the screw 300 is coupled to the 120, the locking pin 1220 is to be inserted without interference with the anti-lift unit 3251. In the present embodiment, the locking pin 1220 is formed to protrude symmetrically from both sides from the side of the drive shaft 120, so that the guide portion 3523 is formed symmetrically on both sides of the ascending prevention portion 3251. Therefore, the shaft hole 3525 formed by the anti-lift portion 3251 formed at the lower end of the lower rotation shaft 350 has a circular shape so that the circular drive shaft 120 is inserted, and is locked at a position symmetrical by 180 degrees. The guide portion 3523 additionally opened to pass through the pin 1220 has a shape.

In addition, as shown in FIG. 19, a rotation engaging end 3522 protruding from the inner surface of the lower rotation shaft 350 is formed from the upper portion of the ascending prevention part 3251. The rotation engaging end 3522 makes contact with the side surface of the engaging pin 1220 to transmit the rotational force of the driving shaft 120 to the screw 300 when the driving shaft 120 rotates. As shown, the rotation engaging end 3522 may be formed to protrude from the inner surface of the shaft hole 351 and the upper surface of the ascending prevention part 3251.

Therefore, when the screw 300 is coupled to the drive shaft 120, the upper end of the drive shaft 120 including the locking pin 1220 through the shaft hole 3525 goes into the shaft hole 351 of the lower rotation shaft 350. It can be inserted, and by rotating the drive shaft 120 or the screw 300 in one direction, it is possible to position the locking pin 1220 on the top of the anti-lift portion 3251. At this time, when the drive shaft 120 is rotated in one direction, as shown in FIG. 21, the locking pin 1220 comes into contact with the rotation locking end 3522 to transmit the rotational force of the driving shaft 120 to the screw 300. have. In addition, when a strong pressure to lift the screw 300 is applied, the upper surface of the lift preventing unit 3251 is caught on the lower side of the locking pin 1220 to prevent the screw 300 from moving upward.

At this time, as shown in FIG. 19, each of the rising preventing portions 3251 formed on both sides around the guide portion 3523 formed open so that the locking pin 1220 moves up and down the inside and outside of the lower rotation shaft 350 without interference. It is preferable that the rotation engaging stage 3522 is formed in the middle of the. Therefore, each of the rising preventing portions 3251 can be separated on both left and right sides with the rotation engaging end 3522 as the center, and one or the other side of the rotating engaging end 3522 and the locking pin according to the rotation direction of the drive shaft 120 The driving force can be transmitted irrespective of the rotation direction of the drive shaft 120 by allowing the 1220 to contact.

In addition, as shown in FIGS. 18 and 21, a stepped step 1222 may be formed on the driving shaft 120, and the lower portion of the driving shaft 120 is formed with a larger diameter than the upper portion by the stepped step 1222. Accordingly, the upper end of the drive shaft 120 can be inserted into the shaft hole 351 of the lower rotation shaft 350 through the shaft hole 3525 based on the stepped step 1222, and the lower end of the drive shaft 120 is the stepped step ( It cannot be inserted into the lower rotary shaft 350 by 1222, and the lower end surface of the lower rotary shaft 350 is caught by the stepped jaws 1222. That is, the stepped step 1222 limits the distance the drive shaft 120 is inserted into the lower rotation shaft 350, and furthermore, when the screw 300 is subjected to a downward pressure by the stepped step 1222, the screw 300 ) To prevent downward movement.

Further, although not shown, when the upper surface of the drive shaft 120 is brought into contact with the upper surface of the shaft hole 351 of the lower rotation shaft 350 and the screw 300 receives downward pressure, the contact causes the screw 300 to It can also be configured to prevent descending movement.

In addition, as shown in FIGS. 22 to 23, a flow plate 3530 and an elastic member 3530 may be formed at the upper end of the shaft hole 351 of the lower rotation shaft 350. A protruding jaw 3526 protruding inward is formed in an inner middle portion of the shaft hole 351 of the lower rotation shaft 350. The flow plate 3529 is inserted into the hole formed by the protruding protrusion 3526, and the lower surface is in a flange shape on top of the cylindrical contact portion 3527 and the contact portion 3527 in contact with the upper surface of the drive shaft 120. It is formed as a locking plate 3528 which is protruding in the direction and is caught on the upper surface of the protruding jaw 3526, and an elastic member 3530 such as a spring is formed between the upper surface of the shaft hole 351 and the locking plate 3528 to allow the flow It elastically supports the plate (3529). The flow plate 3529 is limited downward by contact between the locking plate 3528 and the protruding jaw 3526, and elastically moves upwards of the shaft hole 352.

Therefore, as shown in FIG. 22, when the contact portion 3528 of the flow plate 3528 and the top surface of the drive shaft 120 do not contact, the flow plate 3530 is formed by the elastic force of the elastic member 3530. The locking plate 3528 is positioned in a state that is caught by the protruding jaw 3526. At this time, when the lower rotation shaft 350 of the screw 300 is inserted into the drive shaft 120 and the shaft hole 351 is pressed and rotated by pressing the screw 300, the top surface of the drive shaft 120 flows as shown in FIG. In contact with the contact portion 3527 of the plate 3522, the flow plate 3530 is moved upward, and the locking pin 1220 is positioned on the rising preventing portion 3251 of the lower rotation shaft 350, and the locking pin 1220 is The rotational motion of the motor may be transmitted to the screw 300 by contacting the rotation engaging end 3522. At this time, since the flow plate 3530 which is elastically supported by the elastic member 3530 and moves upward may be limited in the upward movement, the screw 300 is provided by the flow plate 3530 when the screw 300 receives a downward pressure. Can prevent the downward movement of the vehicle.

Next, a modified example of the structure for preventing upward movement of the screw 300 according to the second embodiment described above will be described with reference to FIGS. 24 to 29.

As shown in FIGS. 24 and 25, a locking protrusion 1230 extending in the axial direction may be formed at an end of the driving shaft 120. At this time, the bottom surface of the locking protrusion 1230 forms a protruding surface protruding in the radial direction of the driving shaft 120. The protruding surface is inserted into the shaft hole 351 of the lower rotation shaft 350 and then contacts the upper surface of the ascending prevention part 3531 to prevent the screw 300 from moving upward.

As an example, the locking protrusion 1230 has a width of the locking protrusion 1230 that is smaller than the diameter of the drive shaft 120 when viewed from one side (Fig. 25A), and the other side rotated by 90 degrees (Fig. 25 As seen in (b)), it protrudes than the diameter of the drive shaft 120, but is formed in a shape that is smaller than the diameter of the shaft hole 351 of the lower rotation shaft 350, and the area of the cross section gradually or stepwise from the bottom to the top. It can be formed to be reduced to.

This is to allow the first protrusion 1241 to be inserted without interference with the ascent prevention part 3451. In this embodiment, since the first protrusion 1241 protrudes symmetrically from both sides of the drive shaft 120, the guide part 3543 is formed symmetrically on both sides of the ascending preventing part 3451.

The power transmission unit 3545 is formed to protrude from the bottom surface of the ascending prevention unit 3451. At this time, the power transmission unit 3545 is preferably formed to protrude from the middle portion of the lower surface of the ascent prevention unit 3451. Accordingly, when the drive shaft 120 rotates, the side surface of the second protrusion 1242 may contact the side surface of the power transmission unit 3545 to transmit the rotational force of the drive shaft 120 to the screw 300. In addition, since the second protrusion 1242 may contact the lower end of the anti-lift part 3451, when the screw 300 descends, the upper end of the second protrusion 1242 is the lower end of the anti-lift part 3451 It is in contact with the surface to prevent the screw 300 from falling.

It is a cross-sectional view, FIG. 37 is a bottom view of FIG. 35, FIG. 38 is a plan view of FIG. 35, and FIGS. 39 and 40 are views illustrating a process of coupling between the drive shaft and the rotational shaft of the screw in FIG. 35.

As shown in FIG. 34, a locking part 1250 protruding in the radial direction of the driving shaft 120 is formed on the driving shaft 120, more preferably in a shape protruding in the radial direction from the side of the driving shaft 120. There can be. In this case, the locking part 1250 may be manufactured integrally with the driving shaft 120, or may be manufactured by forming a hole penetrating through the driving shaft 120 to force a pin into the hole.

A shaft hole 351 is formed from the lower end of the rotation shaft 350 to the inside, and the upper end of the driving shaft 120 is inserted into the shaft hole 351 to be coupled. At the lower end of the rotation shaft 350, a lift preventing portion 3551 protruding from the inner surface of the shaft hole 351 in the form of a flange for a predetermined distance in the radial center direction may be formed. When the screw 300 is subjected to an upward pressure, the locking part 1250 located on the upper surface of the upward preventing part 351 may contact to prevent the screw 300 from moving upward.

In the drawings of FIGS. 35 to 40, only the rotation shaft 350 is shown, and the illustrated rotation shaft 350 may be separately mounted on the screw body 310. Further, although not shown, the illustrated rotation shaft 350 may be formed integrally with the screw body 310.

An extension portion 3559 extending upwardly is formed on the top surface of the contact portion 3556. The extension part 3559 may extend above the top of the screw 300. At this time, between the top surface of the shaft hole 351 of the rotation shaft 350 and the top surface of the contact portion 3556, an elastic member 3554 may be formed in a form inserted into the extension portion 359. Accordingly, when the rotation engaging portion 3555 moves upward, an elastic force may be stored in the elastic member 3554.

At this time, the extension part 359 has a rectangular cross section. In the drawings, the cross section is formed in a rectangular shape, but is not limited thereto.

In the following description, the differences will be mainly described as compared to the above-described embodiment with reference to FIGS. 1 to 14.

First, compared to the above-described embodiment, the biggest difference is that in the above-described embodiment, the juice drum 400 is disposed between the housing 200 and the screw 300, but in this embodiment, the juice drum 400 is omitted. Instead, the shape of the screw 300 is modified. In the present embodiment, the screw 300 is configured to be separated and coupled to the first module 360 and the second module 380, hereinafter, in more detail with reference to the drawings for the screw 300 according to the embodiment of the present invention. I will explain it clearly.

It can be formed as Some sections may be cut off little by little, but generally, a continuous screw thread 320 is formed.

When the first module 360 and the second module 380 as described above are combined, the inner diameter of the first body 361 of the first module 360 is the outer diameter of the second body 381 of the second module 380 Larger, the first module 360 is wrapped and coupled to accommodate the second module 380, and the rib 382 of the second module 380 is inserted and coupled into the slit 362 of the first module 360. Then, the portion of the first body 361 in which the slit 362 is not formed and the portion of the second body 381 where the rib 382 is not formed are combined in a radial direction.

At this time, as the rib 382 of the second module 380 is inserted into the slit 362 of the first module 360, a predetermined gap is formed between the slit 362 and the rib 382. The juice is introduced into and discharged into the screw 300 through the gap, and the debris separated from the juice is collected in the lower portion between the screw 300 and the housing 200 and discharged to the outside.

In addition, when the first module 360 and the second module 380 are coupled, a gap is formed between the outer surface of the second body 381 and the inner surface of the first body 361 to form a separation space. I can do it. Juice flowing into the spaced space through the gap through the clearance may move downward between the first module 360 and the second module 380. In this case, a juice discharge hole 385 may be formed under the second body 381. The juice collected under the spaced space between the first module 360 and the second module 380 through the juice discharge hole 385 may be introduced into the inside of the screw 300.

Therefore, in this embodiment, compared to the above-described embodiment, the material is compressed between the housing 200 and the screw 300 without the need to arrange a separate juice drum 400 between the screw 300 and the housing 200. And the pulverized juice is separated into juice and waste, and the generated juice flows into the screw 300 and is discharged through the juice outlet 250, and the waste transferred under the housing 200 is separated and discharged through the waste outlet. Accordingly, the first rib tuck 280 and the second rib tuck corresponding to the first rib tuck 420 and the second rib tuck 425 positioned on the inner surface of the inner module 410 of the juice drum 400 described above. The configuration of 285 may be formed on the inner surface of the housing 200 as shown in FIG. 47.

The shape of the extension part of the first screw thread 320-1 above the screw 300 is the same as the embodiment described above with reference to FIGS. 1 to 14, and as shown in FIGS. 45 to 46, the first screw thread ( The shape of the extension part of 320-1) can be modified into a semicircular shape and a cotyledon shape as well as a hook shape.

In addition, in the above-described embodiment, the housing 200 is formed separately into the lower housing 210 and the upper housing 220, but in this embodiment, the housing 200 is formed integrally.
