Description

Juicer screw and juicer using the same

The present invention relates to a juicer screw and a juicer using the same, and more particularly, to a juicer screw used for 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.

In a conventional juicer, the material was put into the inlet and crushed 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.

Recently, in order to improve the juice efficiency of the juicer, research on each of the components constituting the juicer is ongoing. In particular, since the screw is a configuration that directly crushes and compresses the juice object, it directly affects the juice efficiency of the juicer. Therefore, active research is being conducted on the structure of the screw.

1 shows a conventional screw, in which the screw according to the prior art has an upper surface 10 formed horizontally on the ground at the top of the screw body, and the screw thread 12 is inclined downward to the side thereof. It is extended, and the object to be juiced is input and transported through each screw thread above. The juiced object injected as above is guided to the lower part of the screw by riding the screw thread surface having an inclination to be compressed.

However, due to the area occupied by the upper surface of the screw, if a material with a large diameter is input from the top of the screw, it is not cut or crushed, but remains on the top of the screw.Therefore, it is a hassle to cut the material in advance before putting the material into the inlet. Rejuvenation occurs. In addition, the upper surface of the screw acts as an obstacle to rapidly moving the juice material to the bottom, resulting in a problem that the juice processing speed is slowed.

In addition, a large-diameter juicer that does not require cutting the material in advance before putting the material in the inlet has been developed, and is typically disclosed in Korean Patent No. 10-1270140. The juicer of the above patent increases the size of the inlet and pre-crushes the large material by the crushing unit and the crushing unit to supply the crushed material to the eccentric side of the screw, so that the size of the screw is not increased. It was made to be able to juice large ingredients.

However, even in this case, the inlet of the material is formed in a shape that protrudes outward from an eccentric position toward one side of the screw rather than the upper part of the screw, resulting in a problem that the shape of the juice juicer becomes large and complicated, especially to one side of the screw. There arises a problem that the length of the screw is lengthened due to the formation of a crushing part that crushes the input material.

Therefore, the object of the present invention is to solve such a conventional problem, by forming a screw thread blade inclined upward in the extending direction of the screw thread with respect to the screw thread extending to the uppermost side of the screw body, It is to provide a juicer screw that can be used in a large-capacity juicer because it is possible to increase the size of the material input into the furnace and quickly transfer the juice to the lower portion of the screw to improve the juice processing speed.

In addition, it is to provide a large-capacity juicer in which the screw is used.

The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems that are not mentioned will be clearly understood by those skilled in the art from the following description.

The object is, according to the present invention, in a juicer screw formed with one or more screw threads helically protruding from the outer circumferential surface of the screw body, wherein the screw thread extending helically to the uppermost side of the screw body is This can be achieved by a juicer screw forming a screw thread blade in the direction of extension.

Here, the screw thread may extend to an upper end of the screw body.

Here, two screw threads may be formed symmetrically around the screw body.

Here, the screw thread blade may be inclined downward in a radial direction.

Here, the screw thread blade may have a convex arc shape in the extending direction of the screw thread.

Here, the screw thread blade may have a straight line shape.

Here, the screw thread blade may be in the shape of a concave arc in a direction opposite to the extending direction of the screw thread.

Here, the upper end of the screw body may be formed such that the radius gradually decreases toward the top.

Here, the screw thread may be formed to protrude beyond the longest radius of the screw body in a radial direction.

In addition, the object, according to the present invention, the main body including a drive shaft protruding upward; A housing having an open upper portion mounted on the upper portion of the main body and having a juice outlet for discharging juice juiced from the juice material and a waste outlet for discharging the remaining wastes to be spaced from the outside; A net drum disposed inside the housing and having a net hole for discharging the juice to the outside; The above-described juicer screw disposed inside the mandrel and rotated by coupling with the drive shaft; And a lid covering the open upper surface of the housing and having an inlet through which the juice material is introduced.

Here, the lid may include a cover portion that covers an upper end of the screw and has a shaft coupling portion formed therein to be coupled to an upper rotation shaft of the screw, and the inlet may be formed on an eccentric side of the cover portion and above the screw.

Here, a part of the inlet may be formed to protrude outside the radius of the screw.

Here, the lid may have an input channel extending in a vertical direction from the inlet so that the juice material moves.

Here, a protrusion protruding in a radial direction to accommodate the inlet may be formed on one side of the upper end of the net drum.

Here, the inner surface of the protrusion may be formed as a downwardly inclined surface.

Here, the circumferential end of the protrusion may be provided with a guide portion whose inner protrusion length gradually decreases.

Here, the guide portion may be formed to extend smoothly with the inner surface of the net drum on which the protrusion portion is not formed.

Here, the guide portion may be formed at an end portion in the rotation direction of the screw.

Here, the guide portion may be formed outside the inlet.

Here, the screw thread blade is formed to be inclined downward in a radial direction, and an inner surface of the cover portion may be formed to be inclined downward in a radial direction according to the shape of the screw thread blade.

According to the screw for the juicer of the present invention and the juicer using the same as described above, the screw thread blade is formed without forming an upper surface on the upper end of the screw, thereby securing a wider space for the material input to the screw top, and entering from the inlet. There is an advantage that the subdivision size of the material can be increased.

In addition, there is an advantage in that the juice processing speed can be increased since the object to be juiced can be quickly transferred to the bottom by forming the screw thread to be inclined downward in the radial direction of the screw thread blade and in the direction in which the screw thread extends downward.

In addition, since a material having a large subdivision size can be fed from the top of the screw rather than from the eccentric side of the screw, there is an advantage in that it is not necessary to increase the length of the screw up and down.

In addition, there is an advantage in that the shape of the entire juicer can be manufactured in a more compact and simple form by introducing a material having a size larger than the radius of the screw through the inlet opened from the upper side of the screw.

That is, the debris separated from the inside of the net drum 300 is made to pass through the net drum discharge hole 312 and the waste discharge hole 202 of the net drum 300 sequentially and exit to the debris outlet 220.

As shown in (b) of FIG. 13, a remnant packing 314 made of a material such as rubber or silicone may be interposed in the net drum discharge hole 312 to block the path. The remnant packing 314 is fixed on only one side, so when no external force is applied, the net drum discharge hole 312 is closed, and when an external force is applied (especially, when pressure is applied from the top to the bottom), it is elastically deformed. It is formed to open the net drum discharge hole 312.

The waste opening/closing mechanism 280 is for opening and closing the movement path of the waste, and may be a means for opening and closing the net drum discharge hole 312 in detail, and may be formed in various forms within the range for achieving this purpose. I can. The waste opening/closing mechanism 280 may be in close contact with the lower end of the net drum discharge hole 312 to open and close the net drum discharge hole 312, and when the waste packing 314 is provided, by supporting the waste packing 314 The net drum discharge hole 312 may be sealed.

As shown in FIG. 9, the waste opening/closing mechanism 280 includes a rotation lever 282 and a rotation panel 284 formed to open and close the mandrel discharge hole 312 according to the rotation of the rotation lever 282. Done. When the remnant packing 314 is provided in the net drum discharge hole 312, the rotating panel 284 may be formed to support the remnant packing 314. The rotation lever 282 is fixed to the lower end of the housing 200 so as to be rotatable with respect to the rotation axis. At this time, the end of the rotation lever 282 is formed to protrude out of the sidewall of the housing 200 so that it is formed to be easily operated while the user is grasped, and the rotation panel 284 by the operation of the rotation lever 282 ) Is formed to open and close the net drum discharge hole 312 while moving. The rotating panel 284 may basically be formed as a means for sealing the moving path of the waste or supporting the waste packing 314.

The degree of opening of the mesh drum discharge hole 312 or the waste packing 314 can be adjusted according to the operation of the rotation lever 282, so that an appropriate amount of waste can be discharged if necessary.

In this way, the waste opening/closing mechanism 280 prevents the waste from being discharged when it is not sufficiently compressed (in a state where the juice is not sufficiently separated). In particular, when the remnant packing 314 is provided, the primary blocking of discharged remnants is made by the remnant packing 314, and the secondary blocking is made by the remnant opening/closing mechanism 280.

The net drum 300 is attached to the inside of the housing 200 and accommodates the screw 400 therein. In addition, as described above, a rotating brush 600 may be formed between the mesh drum 300 and the housing 200. The juice material injected from the inlet 114 of the lid 100 is crushed and compressed by the screw thread blade 425 at the top of the screw 400 and transferred to the lower portion to be located between the mandrel 300 and the screw 400. do. The material located between the mesh drum 300 and the screw 400 is compressed and crushed while moving downward along the screw 400, and the juice juiced in this process is formed on the side of the mesh drum 300. ) Through the mesh drum 300 is discharged to the outside.

The mandrel 300 is formed in a shape in which the upper and lower portions are opened, and the radius increases toward the upper portion of the cylinder or overall. A bottom ring 310 in which an insertion hole 311 is formed so as to surround the lower ring 412 of the screw 400 is formed at the lower end of the net drum 300 to constitute the bottom surface of the net drum 300. At the edge of the upper surface of the bottom ring 310, an arc-shaped discharge inclined surface 316 that gradually increases in depth in the rotational direction of the screw 400 is formed, and at the end of the discharge inclined surface 316, the debris after juice is removed from a mandrel. 300) A net drum discharge hole 312 is formed to discharge to the outside. The net drum discharge hole 312 is connected to the waste discharge port 220 of the housing 200 so that the waste may be discharged to the outside.

A plurality of mesh holes 302 are formed in the upper and lower portions of the mesh drum 300 along the surface of the mesh drum. Since the size of the material decreases from the top to the bottom, the size of the net hole 302 may be formed to gradually decrease as the material goes from the top to the bottom so that non-juice materials are not discharged through the net hole 302. In addition, it is preferable that the mesh hole 302 increases the size of the mesh hole 302 in the radial direction so that the juice in the mesh hole 302 can be smoothly discharged. At this time, the size of the mesh hole 302 is gradually increased in the radial direction, or by forming a stepped in the middle of the mesh hole 302, the outer surface of the mesh drum 300 is greater than the mesh hole 302 on the inner surface of the mesh drum 300. The network hole 302 can be formed to be large.

The first rib tuck 320 is formed to protrude in the longitudinal direction from the upper end to the lower end of the inner surface of the mesh drum 300 and is positioned between the screw 400 and the mesh drum 300 together with the rotating screw 400 It plays the role of crushing the material to be used. At this time, it is preferable that the protrusion height of the first rib tuck 320 is formed to decrease as it goes downward so that the material can be crushed more finely as the material is transferred to the lower portion along the screw 400 by rotation of the screw 400. A stepped jaw may be formed in the middle of the first rib jaw 320 depending on the shape of the outer peripheral surface of the screw 400 mounted therein. At this time, the juice generated in the process of pulverizing and compressing the material due to the interaction between the upper portion of the screw 400 and the first rib tuck 320 is discharged to the outside of the mesh drum 300 through the mesh hole 302.

Between the surfaces in which the upper and lower mesh holes 302 are formed, the rigidity of the mesh drum 300 is reinforced with a ring-shaped sealing structure. In addition, since the material is pulverized more finely at this part, it is formed in a closed structure rather than a network structure, and in the process of being pulverized, debris escapes to the net hole 302 and prevents getting caught in the net or rotting inside the juice. To get In addition, a plurality of second rib protrusions 330 protruding in the longitudinal direction are formed on the inner side in the circumferential direction to further finely crush the material.

The first rib tuck 320 described above is formed to extend over the upper and lower ends of the inner side of the mesh drum 300, but the second rib tuck 330 is formed in the middle of the mesh drum 300 to form the first rib tuck 320 and In comparison, its length is short. In addition, the first rib tuck 320 may be formed in one or more in the circumferential direction of the mandrel 300, and the second rib tuck 330 is the first rib tuck 320 in the circumferential direction. It is desirable to form a much larger number than that so that the material is finely ground. In this case, the second rib tuck 330 may also be formed to have a lower protrusion height toward the bottom, like the first rib tuck 320.

The mesh hole surface formed under the second rib tuck 330 has the closest distance to the screw 400, and the material is crushed more finely with a strong pressure according to the rotation of the screw 400, and juice is generated by compression. .

At this time, a protrusion 305 protruding in the radial direction is formed on one side of the upper end of the mandrel 300 according to the present embodiment so that the upper opening of the net drum 300 accommodates the inlet 114 of the lid 100 described above. Can be formed. That is, as shown, the top surface of the mesh drum 300 is not formed in a circular shape, but one side is formed to protrude in the radial direction, so that the radial edge of the inlet 114 and the protrusion 305 of the mesh drum 300 ) To be connected up and down, but the upper opening of the mandrel 300 including the protrusion 305 to accommodate the inlet 114. The inner surface of the protrusion 305 is formed as an inclined surface.

As described above, in the present invention, the cross-sectional width direction of the inlet 114 may be formed to protrude in the radial direction of the screw 400. By connecting the upper edge of the inlet 114 and the mesh drum 300 through the protrusion 305, the material crushed and compressed by the screw thread blade 425 facing the top of the screw 400 from the inlet 114 is meshed. It is possible to prevent being introduced into the space between the net drum 300 and the housing 200 without flowing into the drum 300. In addition, the size of the cross-sectional area into which the juice material is injected from the top of the screw 400 can be expanded while maintaining the size of the screw 400 by the configuration of the inlet 114 and the protrusion 305 described above.

As described above, the top surface of the mandrel 300 may be pressed by the stepped jaws 118 formed in the circumferential direction of the inner surface of the lid 110 of the lid 100. In the circumferential direction, the stepped portion 118 is not formed at the portion where the inlet 114 is formed, and the protruding portion 305 protruding in the radial direction from the upper end of the mandrel 300 is formed at the portion where the stepped portion 118 is not formed. The top of is located. The inner surface of the protrusion 305 is formed as an inclined surface facing the inside of the mandrel 300, and the juice material introduced into the protrusion 305 is crushed and compressed by the screw thread blade 425 at the top of the screw 400 The net drum 300 can be smoothly introduced into the inside by its own weight.

In this case, as shown in FIGS. 10 and 11, a guide portion 306 may be formed at an end portion of the protrusion 305 in the circumferential direction in which the protruding length of the inner surface gradually decreases. Therefore, the stepped portion is not formed at the circumferential edge of the protrusion 306, but may be connected to the inner side of the mandrel 300 in which the protrusion 306 is not formed and extend smoothly in the circumferential direction. If the guide part 306 is not formed as described above, the juice material may not be smoothly transferred downward because the juice material is caught in the stepped jaw formed by the edge of the protrusion 305 and the inner surface of the mesh drum 300, but the guide part By 306, the inner surface formed by the protrusion 305 and the inner surface of the mandrel are naturally extended so that the juice material rotates with the rotation of the screw 300 and can be smoothly transferred downward. It is preferable that the guide part 306 is formed at an end of the screw 400 in the rotational direction of both ends of the protrusion 305. In addition, as shown in Figure 11, the protrusion 305 is formed to be connected to the radial edge of the inlet 114, and is formed longer than the inlet 114 in the circumferential direction, so that the guide portion 306 is the inlet 114 Is formed on the outside of. Therefore, it is preferable that the guide portion 306 does not interfere with the transfer of the juice material flowing downward from the inlet 114.

The screw 400 is disposed inside the mesh drum 300 to receive power from the drive shaft 510 of the main body 500 and rotates at a low speed around the rotation axis, and is located between the mesh drum 300 and the screw 400. The material is moved to the bottom, and the juice is pressed and pulverized by interaction with the mesh drum 300.

The screw 400 may be formed to include a screw body 410 rotating about a rotation axis and one or more screw threads 420 that are helically protruding from the outer peripheral surface of the screw body 410.

As shown in FIG. 16, the screw body 410 may be divided into upper and lower parts with the largest radius of the screw body 410 as the center. The lower portion of the screw body 410 is formed such that the radius gradually decreases toward the bottom, and the radius decreases toward the bottom, thereby forming a space in which the waste separated by the juice is located. However, the lower shape of the screw body 410 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 410 is formed such that the radius gradually decreases as it goes upward, and the width of the change in the radius according to the height change is greater than that of the lower portion of the screw body 410 as shown. Therefore, the uppermost end of the screw body 410 is formed to have the smallest radius and gradually increase in radius toward the bottom. According to this shape, a material having a large size is gradually reduced in size by compression and crushing. It forms a space that can be used. In other words, since the diameter of the upper portion of the screw body 410 gradually increases as it goes downward, the size of the space through which the material formed by the screw body 410 together with the screw thread 420 is transported gradually increases along the transport direction of the material. It becomes smaller. That is, the material is compressed and crushed by the rotation of the screw 400 to gradually decrease in size and move under the screw 400 along the transfer space gradually decreasing along the downward screw thread 420 will be.

The lower portion of the screw body 410 has an insertion space inside so that it can be inserted into the waterproof cylinder 240 on the bottom of the housing 200, and the lower rotation shaft is formed to protrude toward the lower portion and is coupled to the drive shaft 510 450 is formed. The lower rotation shaft 450 may be formed as a square shaft hole 452, and as described above, the shaft hole 452 of the lower rotation shaft 450 is inserted into the square drive shaft 510 and can be directly coupled. When the brush rotation means is formed in the lower portion of the housing 200 to rotate the brush 600, the shaft hole 452 of the lower rotation shaft 450 may be inserted and coupled to the upper end of the first gear shaft of the brush rotation means. .

An upper rotation shaft 440 protruding to the outside may be formed at an upper end of the screw body 410. As described above, the upper rotation shaft 440 may be inserted into the shaft coupling part 112 formed on the inner surface of the lid part 110 of the lid 100 to be rotatably fixed.

The screw thread 420 is formed protruding from the outer circumferential surface of the screw body 410 in the form of a spiral, by which the object of juice is squeezed into a narrow gap between the screw 400 and the mandrel 300 by the screw thread 420 It is transferred to the lower side. At this time, it is preferable that the screw thread 420 protrudes to contact or close to the mesh drum 300. As described above, since the upper portion of the screw body 410 has a smaller radius toward the top, the protruding height of the screw thread 420 increases toward the upper portion of the screw body 410. At this time, the screw thread 420 formed on the upper end of the screw body 410 may be formed to protrude beyond the longest radius of the screw body 410.

The screw thread 420 may be formed as one or a plurality, in the present invention, any one thread extends to the upper end of the screw body 410 in the form of a spiral as shown. At this time, it is preferable that two screw threads 420-1 and 420-2 extending to the top of the screw body 410 are formed symmetrically around the screw body 410 as shown. As the screw 400 is formed in a symmetrical shape, vibration caused by rotation can be minimized when the screw 400 rotates. At this time, the two screw threads extending to the upper end of the screw body 410 will be referred to as a first screw thread 420-1 and a second screw thread 420-2 and will be described later.

At this time, in the present invention, the first screw thread 420-1 and the second screw thread 420-2 are screw threads 420-1 and 420 when the screw threads 420-1 and 420-2 extend upward. -2) A screw thread blade 425 is formed at one end in the extending direction. Conventionally, as shown in FIG. 1, an upper surface 10 horizontal to the ground is formed at the top of the screw 400, and the upper surface 10 and the screw thread 12 are connected, so that the screw thread 12 is extended. No screw thread edge was formed in the direction. However, in the present invention, the first screw thread 420-1 and the second screw thread 420-2 are not only the protruding directions in which the screw threads 420-1 and 420-2 protrude, but also the screw threads 420-1, 420-2) A screw thread blade 425 is formed on the top in the extending direction of the screw threads 420-1 and 420-2. As the screw threads 420-1 and 420-2 are formed to extend upward in a spiral shape, the upper screw thread blade 425 forms an upwardly inclined blade in the axial direction.

In addition, as shown in FIG. 16, the screw thread blade 425 at the upper end of the first screw thread 420-1 and the second screw thread 420-1 is formed to be inclined downward in the radial direction. In this way, as the screw thread blade 425 is formed to be inclined downward in the radial direction, the inner side of the cover portion 110 of the above-described lid 100 is also formed to be inclined downward in the radial direction according to the shape of the upper end of the screw 400. , The inner surface of the cover portion 110 may be formed to be close to the screw thread blade 425.

In this way, in the present design, the screw thread blade 425 is formed on the top of the screw 400 in the extending direction of the screw threads 420-1 and 420-2. Therefore, the juice material located at the inlet 114 can be pulverized by the rotation of the screw thread blade 425, compared to the case of forming a horizontal upper surface 10 on the top of the screw 400 It is possible to secure a wider space through which the juice material flows into the upper side through the inlet 114. Accordingly, the size of the juice material injected from the upper portion of the screw 400 may be increased, and as described above, the inlet 114 protrudes in the radial direction of the screw 400, thereby maximizing the size.

In addition, as the first screw thread 420-1 and the second screw thread 420-2 are formed in a spiral shape, a downward inclined surface is formed. Further, the screw thread blade 425 at the upper end of the first screw thread 420-1 and the second screw thread 420-2 is formed to be inclined downward in the radial direction, and the screw thread at the upper end of the screw 400 The surface also forms a downward slope in the radial direction. Accordingly, the juice material crushed and compressed to a smaller size by the screw thread blade 425 can be smoothly transferred downward along the screw thread surface. That is, the juice material located on the screw thread surface at the top of the screw 400 is not concentrated on the screw body 410 side, but is widely distributed in the radial direction and can be moved downward along the screw thread surface. Therefore, the juice material can be quickly transferred to the lower portion of the screw 400, thereby increasing the juice processing speed.

At this time, the screw thread blade 425 may have a convex arc shape in a direction in which the screw threads 420-1 and 420-2 extend upward as shown in FIGS. 14 to 18. Alternatively, as shown in FIG. 19, the screw thread blade 425 may have a straight line shape. In addition, as shown in FIG. 20, the screw thread blade 425 may have a concave arc shape in the opposite direction from which the screw threads 420-1 and 420-2 extend. In the case of FIGS. 19 and 20, the screw thread blade 425 is preferably formed to be inclined downward in the radial direction.

In addition, as shown, the third screw thread 420-3 formed in a spiral downward starting from the middle portion of the screw body 410 is the first screw thread 420-1 and the second screw thread 420 -2) It can be formed in plurality. Therefore, the width between the adjacent screw threads 420 formed in the screw body 410 is formed to have a relatively wide gap in the upper portion of the screw body 410, and a plurality of screws are formed in the lower portion of the screw body 410. It is formed to have a relatively narrow gap by the thread 420. That is, the upper side of the screw 400 mainly performs a function of crushing a large juice object, and the lower side of the screw 400 may mainly perform a juice function by crushing and pressing.

In addition, a plurality of debris guide jaws 414 protruding outside the radius of the lower end of the screw body 410 may be formed in a circumferential direction. When the screw 400 rotates, the remnant guide 414 performs a function of sweeping down debris separated by juice and transferred under the mandrel 300 to the lower side. In this way, the dregs caught under the mandrel 300 can be smoothly removed by the dregs guide 414 formed on the outer circumferential surface of the lower end of the screw 400 to further increase the juice efficiency.

The lower end of the screw 400 on which the waste guide protrusion 414 is formed is formed to be stepped radially inward. In general, when the pressure to push the debris is small or a part of the debris gets caught in the valley of the screw thread 420, the discharge of the debris is not smooth. When the waste is not discharged smoothly, a high load is generated on the screw 400 and the overall juice efficiency is degraded. By the way, according to the present invention, the lower end of the screw 400 is formed to be stepped inward in the radial direction, and the debris guided to the lower end of the screw 400 can be discharged while receiving the juice pressure at the upper stepped portion. In addition, as described above, the lower end of the screw 400 performs a function of sweeping the debris pushed to the lower end of the screw 400 by the debris guide 414 protruding outward from the radius to further increase the juice efficiency. do.

The main body 500 is supported from the bottom surface, and the above-described housing 200 is attached to the top.

A plurality of fixing protrusions 502 are formed on the upper surface of the main body 500, and a fixing groove (not shown) is formed at the corresponding position of the fixing protrusion 502 on the lower surface of the housing 200 to be fixed to the fixing protrusion 502 The coupling state between the main body 500 and the housing 200 may be firmly maintained by inserting a groove.

A driving unit for rotating the screw 400 may be disposed inside the main body 500. The drive unit may be composed of a motor and a reducer, but may be composed of only a low-speed motor without a reducer. Unlike conventional blenders that finely crush materials by rotating a rotating blade at high speed, in the present design, juice is performed by separating juice and debris by compressing and pulverizing the material by rotating the screw 400 at a low speed. Since it is related to the group, the screw 400 is rotated at low speed.

At this time, the drive shaft 510 of the motor protrudes from the upper surface of the main body 500, and the drive shaft 510 is directly coupled with the screw 400 or coupled with the aforementioned first shaft gear 252 to rotate the screw 400 Let it be.

The scope of the present invention is not limited to the above-described embodiments, but may be implemented in various types of embodiments within the scope of the appended utility model claims. Without departing from the gist of the present invention as claimed in the utility model claims, anyone with ordinary knowledge in the technical field to which the subject design belongs is considered to be within the scope of the description of the claims of the present invention to the various ranges that can be modified.
