At this time, the bushing portion 218 may be integrally formed on the bottom surface of the hopper housing 215 by insert injection.

Between the connection hole 2152 and the bushing part 218, the hopper bottom faces and the bushing even if the screw 230 is lifted by the load during the juice process, so that the radius of the cone decreases as it goes upward. Since the coupling force between the portions 218 can be maintained firmly, it is possible to prevent deformation due to the injury of the screw 230.

Inside the bushing 218, a hole is formed in a vertically open shape, and the power transmission unit 219 is inserted. When the screw 230 rotates while the upper rotation shaft 233 of the screw 230 is inserted into the power transmission unit 219, the power transmission unit 219 inserted into the bushing unit 218 is inserted into the bushing unit 218 ) Since it rotates inside, the bushing portion 218 is preferably formed of a material that is not easily deformed by friction generated when the power transmission portion 219 rotates.

The power transmission unit 219 may be composed of an engaging portion 2191 and an upper protrusion 2195. The outer surface of the coupling portion 2191 is also formed in a conical shape with a decreasing radius toward the upper portion so as to correspond to the shape of the inner surface of the bushing portion 218, which is formed in a conical shape with a decreasing radius toward the upper portion. The inside of the coupling portion 2191 is formed with a shaft hole 2192 into which the upper rotation shaft 233 of the screw 230 is inserted. The upper rotating shaft 233 of the screw 230 is formed as an angular axis, and the axial hole 2192 may be formed as an angular axial hole. In this embodiment, the upper rotation axis 233 of the screw 230 is formed by a hexagonal axis, and the axis hole 2192 is formed by a 12-angle axis hole 2192 that is a multiple of 2 times. The shaft hole 2192 formed in the power transmission unit 219 may also be formed as a hexagonal shaft hole to correspond to the shape of the upper rotational shaft 233 of the screw 230, but when it is formed as a shaft hole at a double angle of 12 The coupling between the upper rotation shaft 233 of the screw 230 and the power transmission unit 219 may be easier. Furthermore, an inclined surface in which the size of the shaft hole is expanded may be formed at the entrance of the 12-angle shaft hole to facilitate the coupling. Therefore, in order to facilitate the coupling between the two members, when the upper rotational shaft 233 of the screw 230 is formed as an n-square angular axis, the axial hole formed in the coupling portion 2191 of the power transmission unit 219 is It can be formed by a 2n square axial hole.

At this time, when the power transmission unit 219 is fastened to the bushing unit 218, the bottom surface of the power transmission unit 219 is positioned above the bottom surface of the bottom surface of the hopper 210.

The upper protrusion 2195 is formed on the upper portion of the coupling portion 2191, and when the power transmission portion 219 is inserted into the bushing portion 218 at the bottom surface of the hopper housing 215, the upper protrusion portion 2195 has a bushing portion ( It penetrates through the hole of 218) and protrudes over the upper surface of the bushing 218 to be located inside the hopper 210. At this time, the upper protrusion 2195 is formed in a quadrangular square shape, and a cut groove 225 is formed on the bottom surface of the cutting portion 225 in a shape corresponding to this, so that the cutting portion 225 can be coupled to the upper protrusion 2195. have. The shape of the upper protrusion 2195 and the shape of the groove 2251 of the bottom surface of the cutting portion 225 corresponding thereto are not limited thereto, and may be variously modified, such as a cross shape or a spline shape.

The screw 2199 is inserted through the shaft hole 2192 of the coupling portion 2191 and screwed into the screw hole 2196 passing through the upper protrusion 2195 and the screw groove 2252 formed in the rotation center of the bottom of the cutting portion 225 By combining, the cutting portion 225 can be firmly fixed to the upper projection portion 2195.

The upper end of the shaft hole 2192 formed on the inner surface of the coupling portion 2191 is formed with a stepped to limit the insertion depth of the upper rotational shaft 233 of the screw 230, and the head of the screw 2199 is provided on the upper side based on the stepped Is located.

As described above, when the inner surface of the bushing unit 218 and the outer surface of the power transmission unit 219 come into contact with each other in the form of a cone having a radius that decreases toward each other, when the screw 230 receives a rising force In order to prevent the injury of the screw 230. Furthermore, as the power transmission unit 219 receives a force to face upward, the power transmission unit 219 and the bushing unit 218 are in a more concentric position, so mechanical stability can be improved.

The cutting unit 225 is rotatably coupled to the bottom surface of the hopper 210 to receive rotational force from the screw 230 through the power transmission unit 219 to rotate and cut and stir the juice material.

The cutting unit 225 may be driven to include a hook-type cutting edge 226 and a horizontal cutting edge 227. At this time, the hook-shaped cutting edge 226 and the horizontal cutting edge 227 may be integrally formed.

The hook-shaped cutting edge 226 is formed to extend upward in the form of a spiral in the direction of rotation of the cutting portion 225 from the center of rotation. The upper end of the hook-type cutting edge 226 is preferably formed in a sharp hook shape as the cross section becomes smaller toward the end. The hook-shaped cutting edge 226 facing upward in the form of a hook mainly plays a role of dividing and crushing the juice material put into the upper portion. At this time, the radially inner surface of the hook-type cutting edge 226 is formed with an inclined curved surface 2601 so that it faces radially outward toward the bottom, and the hook-type cutting edge 226 rotates and the hook-type cutting edge 226 ) Allows the crushed juice material to be smoothly moved downward along the curved surface.

The higher the upper height of the hook-type cutting edge 226, the higher the crushing effect, and is preferably formed at least higher than the height of the upper surface of the horizontal cutting edge 227. In addition, the radial length of the hook-shaped cutting edge 226 is preferably formed to be as long as possible in the radial direction in the range that does not interfere with the inner surface of the hopper 210.

The horizontal cutting edge 227 is formed to extend horizontally on the bottom surface of the hopper 210. The horizontal cutting edge 227 is preferably formed to have a predetermined thickness even in the vertical direction. At this time, the end of the horizontal cutting edge 227 may be formed to gradually decrease its height. The horizontal cutting edge 227 serves to secondaryly crush the juice material that has been crushed and moved down by the hook-shaped cutting edge 226 by the blade formed at the top, and the horizontal cutting edge 227 is predetermined. As it is formed to have a thickness, the juice material located on the bottom surface of the hopper 210 is pushed to be smoothly discharged through the discharge hole 217. This is because if the horizontal cutting edge 227 is thin, the juice material located on the bottom surface of the hopper 210 may not be pushed and may be lost.

The horizontal cutting edge 227 is preferably such that the hook-type cutting edge 226 extends at a position opposite to the direction in which the hook-shaped cutting edge 226 extends from the rotation center of the cutting portion 225, but is not limited thereto. At this time, the horizontal cutting edge 227 is preferably formed in a curved shape in the direction opposite to the rotation direction of the cutting portion 225.

The horizontal cutting edge 227 is also preferably formed to be as long as possible in the radial direction in the range that does not interfere with the inner surface of the hopper 210, like the hook-type cutting edge 226.

A bottom groove 2701 dug to a predetermined depth may be formed on the bottom surface of the horizontal cutting edge 227. This may serve to reduce the weight of the cutting portion 225.

As described above, at the center of rotation of the bottom surface of the cutting portion 225, a square groove 2251 may be formed to correspond to the shape of the upper protrusion 2195 of the power transmission portion 219 formed in a square square shape, and a square groove ( 2251) a screw groove 2252 in which a screw is fastened is formed. By fastening the cutting portion 225 using a screw 2199 in a state where the square groove 2251 is fitted to the upper projection portion 2195 of the power transmission portion 219, the cutting portion on the inner bottom surface of the hopper housing 215 The 225 can be rotatably mounted.

At least one first inner protrusion 2155 may be formed on the inner surface of the hopper 210 to protrude inwardly in the vertical direction as shown in FIG. 9. The first inner protrusion 2155 interacts with the hook-type cutting edge 226, and the juice material injected inside the hopper 210 serves to catch and catch the first inner protrusion 2155, thereby cutting the hook-type cutting edge ( 226) to improve the crushing efficiency. If there is no first inner protrusion 2155, the juice material may rotate with the hook-type cutting edge 226 and not be cut. However, when the juice material is supported in the rotational direction by the first inner protrusion 2155, rotating the hook-shaped cutting edge 226 can easily break the juice material. Therefore, it is preferable that the first inner protrusion 2155 has a relatively large height protruding inward as compared to the second inner protrusion 2157 described later so that the juice material can be supported in the radial direction.

One side of the outer circumferential surface of the hopper 210 is indented by the interference prevention groove 2154 described above, and as illustrated, the first inner protrusion 2155 may be configured together with the interference prevention groove 2154.

 At this time, the lower end of the inner projection is preferably formed to be located at the upper end of the hook-type cutting edge 226, as shown in Figure 9 (a), the lower end of the first inner projection 2155 is a hook-shaped cutting unit In order to allow the upper end portion of the 225 to pass, a through groove 2156 penetrating both sides in the shape of the upper end portion of the hook-shaped cutting portion 225 may be formed. As the lower end of the first inner projection 2155 is formed in this way, the lower end of the first inner projection 2155 and the upper end of the hook-type cutting edge 226 may be positioned to overlap each other. At the same time, it is possible to form a larger radial length of the hook-type cutting edge 226, thereby improving the cutting efficiency.

In addition, at least one second inner protrusion 2157 may be formed on the inner surface of the hopper 210 to protrude radially inward from the position where the end of the horizontal cutting edge 227 is located. The second inner protrusion 2157 may interact with the horizontal cutting edge 227. The juice material located on the bottom surface of the hopper 210 is partially pushed into the discharge hole 217 as the horizontal cutting edge 227 rotates, and partly moves radially outward by centrifugal force. At this time, the juice material located on the upper portion of the horizontal cutting edge 227 may not flow into the discharge hole 217, but a problem may occur in the upper part of the horizontal cutting edge 227. At this time, the juice material pushed outward from the upper portion of the horizontal cutting edge 227 by the centrifugal force may collide with the second inner protrusion 2157 and fall off from the horizontal cutting edge 227.

In this embodiment, the second inner protrusion 2157 is formed under the first inner protrusion 2155. In addition, by forming the discharge hole 217 under the vertical of the first inner projection 2155 and the second inner projection 2157, it is cut through the first inner projection 2155 and the second inner projection 2157 and separated. The juice material to be dropped vertically down to be directly supplied into the juice drum 280 through the discharge hole 217.

Hereinafter, the screw 230, the juice separation drum 260, and the juice drum 280, which constitute the juicer 200 and located under the hopper 210, will be described. First, the screw 230 will be described first with reference to FIGS. 16 to 19.

FIG. 16 is a perspective view of the screw shown in FIG. 4, FIG. 17 is a side view of FIG. 16, FIG. 18 is a perspective view showing the bottom of the screw shown in FIG. 16, and FIG. 19 is shown in FIGS. 16 to 18 It is a modification of the screw.

The screw 230 is mounted inside the juice separation drum 260 to receive rotational force from the drive shaft 130 of the main body 100 to perform rotational motion, and compress and crush the juice material together with the juice separation drum 260.

The screw 230 may include a screw body 231 and a screw thread 232 protruding in a spiral form on the outer surface of the screw body 231.

The screw body 231 may be divided into upper and lower portions around a portion having the largest radius of the screw body 231 as illustrated. At this time, the upper part forms a cutting section for additionally cutting the juice material input from the hopper 210, and the lower part forms a juice section that compresses the juice material in earnest under the cutting section to generate juice.

The lower portion of the screw body 231 is formed to gradually decrease in radius as it goes down, so that the radius becomes smaller as it goes down to form a space where debris separated by juice is located. However, the lower shape of the screw body 231 is not limited thereto, and may be formed in a straight line, for example, without changing the radius.

In addition, the upper portion of the screw body 231 is formed to gradually decrease in radius as it goes upward, as shown in the figure, the change width of the radius according to the height change is larger than that of the lower portion of the screw body 231. The uppermost end of the screw body 231 is formed such that the radius is the smallest and the radius increases gradually as it goes down, and a material having a large size according to such a shape can be transported while gradually decreasing in size by compression and grinding. It forms a space. In other words, since the diameter of the upper portion of the screw body 231 gradually increases as it goes down, the size of the space through which the material formed by the screw body 231 along with the screw thread 232 is gradually increased along the material transport direction. It becomes smaller. That is, the material is compressed and crushed by the rotation of the screw 230, and the size thereof gradually decreases, and the movement of the screw 230 moves downward along the transport space gradually decreasing along the screw thread 232 formed in the downward direction. Is done.

The screw thread 232 is formed to protrude in the form of a spiral on the outer circumferential surface of the screw body 231, by which the object to be squeezed is squeezed into a narrow gap between the screw 230 and the juice separation drum 260 by the screw thread 232. Will be transported down. At this time, it is preferable that the screw thread 232 protrudes to be in contact with or close to the juice separation drum 260. As described above, since the radius of the upper portion of the screw body 231 becomes smaller as it goes upward, the protruding height of the screw thread 232 becomes larger as it goes toward the upper portion of the screw body 231.

The screw thread 232 may be formed in one or a plurality, in the present design, any one of the plurality of screw threads 232 (first screw thread (232-1)) is the top of the screw body 231 It can be used to form an outer blade screw 230 to form an outer blade 2321 at the upper end of the screw body 231. When using a double-edged screw in which two screw threads are formed to extend symmetrically to the top of the screw body 231, a large load is applied, but the outer blade screw 230 is used in the present invention, but is not limited thereto.

At this time, in the present invention, the radius of the outer edge 2321 of the upper end of the screw body 231 may be formed to protrude outwardly larger than the longest radius of the screw body 231. In this way, by maintaining the size of the screw body 231 as before, the radius of the outer blade 2321 is formed to be larger than the longest radius of the screw body 231, thereby ensuring a wider space for the juice material to be introduced from the top. I can do it. This allows the juice material fractionated from the upper hopper 210 to be more smoothly introduced into the screw 230.

As illustrated, a second screw thread 232-2 formed in a spiral shape starting from the top of the screw body 231 which is a juice section may be formed, and the first screw in the lower portion of the screw body 231 may be formed. Another plurality of third screw threads 232-3 may be formed between the threads 232-1 and the second screw threads 232-2. Therefore, the width between neighboring screw threads 232 formed in the screw body 231 is formed to have a relatively wide gap at the upper portion of the screw body 231, and a plurality of screws at the lower portion of the screw body 231. It is formed to have a relatively narrow gap by the threads 232. That is, the cutting section, which is the upper portion of the screw 230, mainly performs the function of crushing a large-scaled juice object, and the juice section, which is the lower portion of the screw 230, is crushed and compressed by rotation of the screw 230 to perform the juice function. Can mainly be done.

In addition, a plurality of debris guide jaws 235 protruding outward from the radius of the lower end of the screw body 231 may be formed in a circumferential direction. The waste guide jaw 235 is separated by juice when the screw 230 rotates, and performs a function of sweeping down the debris transported below the juice separation drum 260. In this way, by removing the residue jammed under the juice separation drum 260 by the residue guide jaw 235 formed on the outer circumferential surface of the screw 230, the juice efficiency can be further increased.

The upper rotational shaft 233 of the screw 230 protruding above the screw body 231 is formed as an angled shaft and coupled to an angled shaft hole 2192 of the power transmission unit 219 to transmit power to the cutting unit 225 do.

In addition, the screw 230, the lower rotating shaft 234, which protrudes downward from the inside emptied into the hollow of the screw body 231, is formed into an angular axial hole and inserted into the angular driving shaft 130 protruding above the main body 100. It is to receive power from the motor 1001. As described in the coupling structure between the screw 230, the upper rotational shaft 233 and the power transmission unit 219, the drive shaft 130 is formed into an n-axis angular axis and the screw 230, the lower rotational shaft 234 is 2n angle It is also possible to facilitate the coupling between the two members by forming a square axial hole of. For example, when the drive shaft 130 is formed with a hexagonal axis, the screw 230 and the lower rotational shaft 234 may be formed with a 12-angled angular hole.

A gripping portion 236 may be formed on the top of the screw body 231. The gripping portion 236 may be formed to protrude from the upper end of the screw body 231 with the outer edge 2321 at a predetermined horizontal angle, which allows the user to use the screw 230 mounted in the juice drum 280 for washing or the like. This is to make it easy to take out with the single blade 2321.

19 shows a modification of the above-described screw 230, in this embodiment, between the cutting section and the juice section, at the boundary of the upper and lower screw 230 in the form of a circular ring or belt (belt) The over-insertion prevention ribs 239 protruding from the screw body 231 along a circumferential direction to a predetermined thickness are formed.

The over-injection prevention rib 239 is intended to prevent an overload due to the pressure of the screw 230 in the juice section when a large amount of the juice material in the cutting section is supplied to the juice section at a time. The gap between the screw 230 and the juice separation drum 260 is reduced by the over-injection prevention rib 239, so that a large amount of juice material can be prevented from being introduced into the space therebetween.

Since the configuration of the rest of the screws 230 except for the over-injection prevention rib 239 is the same as described above, a description of the same configuration will be omitted.

Hereinafter, the juice separation drum 260 according to the embodiment of the present invention will be described in more detail with reference to FIGS. 20 to 21.

20 and 21 are exploded perspective views of the juice separation drum shown in FIG. 4, and FIG. 22 is a partially cut perspective view of the juice separation drum shown in FIG.

As illustrated, the juice separation drum 260 according to the present invention may be configured by a combination of an inner module 240 and an outer module 250. Here, the inner module 240 and the outer module 250 may be made of a material such as polyetherimide (PEI).

The inner module 240 has a generally cylindrical shape, and the upper and lower sides may be opened. Here, the inner module 240 includes a plurality of inner plate portions 241, and a plurality of slits 242 are formed long in the vertical direction by the plurality of inner plate portions 241.

Here, the plate portion 241 is named for convenience of explanation, and when the cylindrical module is divided into a hole portion in which the slit 242 is formed and a plate portion in which the slit 242 is not formed, the slit 242 is not formed. The plate portion is defined as a "plate portion 241".

In this case, the width of the slit 242 on the upper side may be smaller than the width of the slit 242 on the lower side. That is, the width of the slit 242 may be narrower toward the upper side.

In addition, a first rib jaw 244 may be formed to protrude on the inner circumferential surface of the inner module 240 in the longitudinal direction. The first rib jaw 244 compresses or crushes the material by interaction with the screw thread 232 according to the rotation of the screw 230. If the first rib jaw 244 is not present, the object to be juice may stagnate without falling down, or the compression force or crushing force may be low or may not occur. At this time, the first rib jaw 244 may be formed on one side of the slit 242 of the inner module.

In addition, a second rib jaw 243 protruding long along the vertical direction may be formed on the inner surface of the inner module 240 in a predetermined number. The second rib jaw 243 transfers the juice material introduced into the juice separation drum 260 to the bottom and performs a function of crushing the juice object. The second rib jaw 243 may perform a function of reinforcing the rigidity of the inner module 240, and may guide a juice object into the juice separation drum 260. In addition, the second rib jaw 243 may perform a function of adjusting the position of the screw 230 and adjusting the juice space.

The protruding height of the second rib jaw 243 may be formed to have the same height from the top to the bottom of the inner module 240, but is preferably formed in a form that gradually decreases from the top to the bottom of the inner module 240 Can be. In addition, the second rib jaw 243 is formed to be inclined downward from the top to the bottom of the inner module 240, protruding toward the screw 230 in the middle portion to form a stepped stepped portion (2431) You can. The stepped portion 2431 may be variously modified in its position, number, or protruding height according to the shape of the screw 230 and the design condition of the screw thread 232. The number and arrangement of the second rib jaws 243 may be variously changed as necessary in consideration of design conditions and efficiency of juice. In an embodiment of the present invention, the formation direction of the second rib jaw 243 is described as an example that is formed vertically in the vertical direction of the inner module 240, but the scope of the present invention is not limited thereto.

At this time, the first rib jaw 244 is formed on the lower inner surface of the inner plate portion 241 (more specifically, one side of the slit 242), and the second rib jaw 243 is the inner surface of the inner plate portion 241 It is formed from the top to the bottom as a whole.

The upper end portion of the inner module 240, as shown, is formed with an extension portion 245 that expands to increase in radius toward the upper portion. Since the upper end of the inner module 240 is expanded in the shape of a trumpet, the outer edge 2321 of the top of the screw 230 inside the extension 245 can rotate without interference.

In addition, a material inflow guide portion 246 which is a curved portion gradually facing inward along a rotation direction of the screw 230 may be formed on one side of the expansion portion 245. If there is no material inlet guide 246, the juice material does not flow down, and a problem may occur with the blade 2321 on the extension 245. When the juice material rotates with the blade 2232, In contact with the material inlet guide 246, it can be guided to move away from the outer edge 2321. Furthermore, it is possible to solve the problem that the material is caught in the material inflow guide portion 246 as it is formed of a smooth inclined surface. The upper surface of the material inflow guide portion 246 is formed so as not to interfere with the bottom surface of the outer blade 2321.

A fitting protrusion 247 that protrudes a predetermined number is formed on a lower surface of the inner module 240. When the inner module 240 is coupled between the outer module 250, the fitting protrusion 247 has an outer module 250. ) Is inserted into the fitting groove portion 258 formed on the bottom surface, thereby joining between the two members 240 and 250.

Next, the outer module 250 will be described. The outer module 250 is composed of a cylindrical shape, and includes an outer plate portion 251 whose upper and lower sides are open and a rib 252 protruding from an inner surface of the outer plate portion 251.

The outer plate portion 251 accommodates the inner module 240 therein and can be detachably coupled between the outer module 250 and the inner module 240. That is, the outer module 250 may be coupled to receive and surround the inner module 240 when coupled with the inner module 240. At this time, the outer module 250 may wrap the inner module 240 to support it.

When the outer module 250 and the inner module 240 move up and down, the rib 252 is inserted into and coupled to the slit 242 under the slit 242 of the inner module 240. At this time, a fine gap formed between the slit 242 and the rib 252 is formed, through which the juice generated inside the juice separation drum 260 can be discharged to the outside.

As described above, in this embodiment, the slit 242 of the inner module 240 and the rib 252 of the outer module 250 are combined to discharge juice through the gap between the slit 242 and the rib 252. Since it forms a ball, it is very easy to clean.

At this time, the rib 252 may be formed to correspond to the shape of the above-described slit 242, the width of the rib 252 becomes narrower toward the upper side, the width of the rib 252 on the upper side of the lower side It may be smaller than the width of the ribs 252.

When the outer module 250 and the inner module 240 are moved up and down by the shape of the rib 252 and the slit 242 as described above, the width is relatively lower than the lower portion of the relatively large slit 242. By inserting the upper portion of the small rib 252, the outer module 250 and the inner module 240 can be easily combined.

In addition, a plurality of juice discharge holes 253 may be formed on the lower side of the outer plate portion 251.

As described above, the juice formed inside the juice separation drum 260 formed by the combination of the inner module 240 and the outer module 250 has slits 242 of the inner module 240 and ribs 252 of the outer module 250. ) Can be discharged to the outside of the juice separation drum 260 by passing through the slit hole which is a fine gap formed between the juice discharge hole 253 formed in the outer module 250.

At this time, the gap formed between the slit 242 and the rib 252 is preferably formed to gradually increase the width of the gap in the radial direction to facilitate the discharge of juice. For example, when the width of the slit 242 is gradually increased in the radial direction, the size of the gap gradually increases in the radial direction.

 Further, the gap is made to be smaller in width in the longitudinal direction, so that the width of the gap is smaller, and it is further finely crushed to prevent debris generated from being discharged through the gap and exerts strong pressure by the screw 230. It is desirable to support.

A drum fixing portion 259 protruding in a horizontal direction with a predetermined number is formed at an upper end of the outer module 250, which is inserted into a drum fixing groove 2802 formed on an upper portion of the juice drum 280, which will be described later, to extract the juice drum ( It is possible to fix the position of the juice separation drum 260 within 280).

In addition, a fitting groove 258 that is dug in a predetermined number is formed on the lower surface of the outer module 250. When engaging the inner module 240 and the outer module 250, the fitting protrusion 247 is the outer module. It is inserted into the fitting groove portion 258 formed on the bottom surface of the 250, and is coupled between the inner module 240 and the outer module 250.

In this embodiment, the juice separation drum 260 that forms the outflow hole by the combination of the inner module 240 and the outer module 250 is used, but a mesh drum having a plurality of circular meshes formed on a surface of a drum widely known in the art You can use it. In addition, in this embodiment, ribs 252 are formed on the outer module 250 and slits 242 are formed on the inner module 240 to discharge juice when the inner module 240 and the outer module 250 are combined. In order to form the outlet hole, the separate ribs 252 are formed on the inner surface of the juice drum 280 without forming the outer module 250, and the juice is discharged by inserting the inner module 240. It may also form an outflow hole.

Hereinafter, the juice drum 280 according to the embodiment of the present invention will be described in more detail with reference to FIGS. 23 to 27.

At this time, the step formed by the stepped hole 313 makes the lower limit of the drive transmission unit 310 by making the drive transmission unit 310 contact the upper end of the drive shaft 130 when the shaft moves downward.

Furthermore, a stepped locking groove 3111 is formed at a lower end of the motor shaft coupling portion 311, and a locking jaw 132 protruding at a predetermined position on the outer circumferential surface of the driving shaft 130 is formed to correspond to this, thereby driving transmission. The lower limit of the drive transmission unit 310 may be configured by allowing the locking groove to contact the locking projection 132 when the unit 310 moves downwardly.

In the middle of the stepped hole 313, an inner protrusion 314 protruding in the axial center direction may be formed inward. The inner protrusion 314 compresses the coil spring 315 by making contact with the upper end of the coil spring 315 when the drive transmission unit 310 moves downward. In addition, when the drive transmission unit 310 moves upward by the elastic energy of the coil spring 315, the inner protrusion 314 contacts the head portion 318, where the head portion 318 is the drive transmission portion ( 310).

In addition, a stopper 3101 for blocking an opening may be formed on an upper end of the driving transmission unit 310. The screw 319 is inserted through the opening of the upper end of the drive transmission part 310 to be coupled to the drive shaft 130, forming a step at the upper end of the drive transmission part 310 and seating the stopper 3101 on the step The opening at the top of the drive transmission unit 310 may be shielded. At this time, the stopper 3101 is to prevent the penetration of juice between the head 318 of the screw 319 and the inner surface of the screw coupling portion 312.

Therefore, when there is no force to press the drive transmission part 310 from the top to the bottom, the drive transmission part 310 is driven by the elastic force of the coil spring 315 as shown in FIG. 31 (a). When the driving transmission unit 310 is pressed from the top to the bottom, the driving transmission unit 310 moves downward in the axis and is positioned at the position of the lower limit as shown in FIG. 31 (b). Is done. At this time, the coil spring 315 is compressed, the elastic energy is stored, and when the pressurization of the upper portion of the drive transmission unit 310 is released, the drive transmission unit 310 is again at the upper limit by the elastic energy of the coil spring 315. It will move elastically to the position.

When the juicer 200 is seated on the main body 100, when the lower rotation shaft 234 of the screw 230 matches the screw coupling portion 312 of the driving transmission unit 310, the driving force of the driving shaft 130 Can be transmitted to the screw 230 by the drive transmission unit 310.

On the other hand, when the lower rotation shaft 234 of the screw 230 does not match the screw coupling portion 312 of the drive transmission unit 310, the screw 230 presses the drive transmission unit 310, The drive transmission unit 310 is moved downward.

In this state, when the motor 1001 is rotated, the drive transmission part 310 coupled to the drive shaft 130 rotates, and the screw coupling part 312 above the drive transmission part 310 is the lower part of the screw 230 It will be in a position to match the rotating shaft 234. At this time, by the elastic energy of the coil spring 315, the drive transmission unit 310 elastically moves upward in the axis, and automatically matches the lower rotational shaft 234 to transmit the driving force of the drive shaft 130 to the screw 230. It becomes possible.
