Hopper 210 is detachably coupled to the upper portion of the juice drum (280). The hopper 210 forms a space for storing the input juice material (eg, fruits, vegetables, grains, etc.). The cut portion 225 rotatably fixed on the bottom surface of the hopper 210 receives power from the screw 230 and rotates to cut and stir the juice material and supply it to the juice drum 280 at the bottom. Therefore, in the present invention, since the cutting of the juice material is made in the hopper 210, it is not necessary to cut the juice material in advance.

The hopper 210 may be largely divided into a hopper housing 215 , a lid part 220 , and a cut part 225 .

The hopper housing 215 has a cylindrical or truncated cone shape and forms a space for receiving the juice material through an open top.

As shown in FIG. 8 , the bottom surface of the hopper housing 215 may be formed detachably from the upper cylindrical body, but is not necessarily limited thereto and may be integrally formed.

The cut portion 225 may be rotatably mounted on the bottom surface of the hopper housing 215 , and the cut portion 225 receives power from the screw 230 inside the juice drum 280 to receive power from the screw 230 and can rotate together.

On the inner surface of the hopper housing 215 , a comb protrusion 2151 protruding inwardly in the longitudinal direction may be formed along the circumferential direction. This is to prevent light juicing materials such as leaf vegetables from adhering to the inner surface of the hopper housing 215 by absorbing moisture and to be easily removed. At this time, it is preferable that the comb-tooth projections are formed on the front inner surface of the hopper housing 215 .

On one side of the outer circumferential surface of the hopper housing 215, a handle portion 216 that allows a user to hold the container may be formed. The handle 216 may be formed to extend from the upper end of one side of the cylindrical hopper housing 215 in a ring shape to the lower end of the hopper housing 215 as shown, and the lower end of the handle 216 must be the hopper housing.

In the drawing, one discharge hole 217 is formed on one side of the bottom surface of the hopper 210, and the larger the number of discharge holes 217 or the size of the area of the discharge hole 217 is, the larger the amount (or larger size). of the juice material may be supplied to the juice drum 280 . However, since a load may be applied to the screw 230 when an excessive amount of juice material is supplied into the juice drum 280, the size of the discharge hole 217 and the size and It is desirable to set the number.

In addition, an inclined surface 2171 inclined toward the discharge hole 217 may be formed on the inner surface of the bottom surface of the hopper housing 215 . At this time, it is preferable that the inclined surface 2171 is formed so as to be inclined downward along the rotational direction of the cutting part 225 . Since the height of the portion in contact with the inclined surface 2171 and the discharge hole 217 is lower than the height of the inner bottom surface of the hopper housing 215 , the juice material can be efficiently guided toward the discharge hole 217 . The juice material that may be fixed or stagnant between the inner surface of the bottom surface of the hopper housing 215 and the horizontal cutting edge 227 of the cut portion 225 by the inclined surface 2171 may be moved downward smoothly.

Furthermore, in the present invention, as shown in FIG. 11 , an inclined surface 2172 may be formed on the outer surface of the bottom surface of the hopper housing 215 (the bottom surface of the hopper 210 ). The inclined surface 2172 is formed to be inclined downward from the discharge hole 217 along the rotational direction of the cutting part 225 so that the juice material can be smoothly supplied to the juice drum 280 through the discharge hole 217 . .

In addition, the safety guide part 223 may also serve to prevent the lid part 220 from rotating in the horizontal direction together with the rotation prevention rib 2224 .

The safety guide part 223 may be formed to protrude to a certain height along the edge of the lower surface of the lid part 220, but as shown in the figure, the protrusion height is gradually reduced from the far side to the hinge coupling part. The lower surface may be formed to be inclined.

The cut part 225 is rotatably coupled to the inner bottom surface of the hopper 210 and receives rotational force from the screw 230 located inside the juice drum 280 to rotate inside the hopper 210, the hopper 210 The juice material injected therein is cut and stirred, and the juice material cut through the discharge hole 217 formed in the lower surface of the hopper 210 is supplied into the juice drum 280 located below the hopper 210 .

In the present invention, the cutting part 225 rotates in a state in which both sides are supported between the lower end and the upper end of the hopper 210 inside the hopper 210 and does not cut the juice material, but one side supported at the lower end of the hopper 210. Since the juice material is cut in the state, an open space is formed on the upper side of the cut portion 225 in the hopper 210 without interference. Accordingly, since the entire upper side of the cut portion 225 forms an open open space, it is possible to cut the juice material with a large size, such as a passing day, into the hopper 210 .

Next, a structure in which the cut portion 225 is rotatably coupled to the bottom surface of the hopper housing 215 and receives rotational force from the screw 230 to rotate the cut portion 225 will be described with reference to FIGS. 8 and 9 . decide to do

A bushing part 218 is disposed in the connection hole 2152 formed in the bottom surface of the hopper housing 215 . The radially inner and outer surfaces of the bushing portion 218 are formed in a cone shape with a radius decreasing toward the top, and protrude in the form of a circular flange at the bottom to form a stepped 2181 . The inner surface of the connection hole 2152 is formed with a conical inclined surface and a locking protrusion 2158 to correspond to the shape of the outer surface of the bushing part 218 . At this time, the bushing part 218 may be integrally formed on the bottom surface of the hopper housing 215 by insert injection.

The connection hole 2152 and the bushing 218 are in contact with each other in the form of a cone whose radius decreases toward the top, so that even when the screw 230 rises due to a load during the juice extraction process, the bottom surface of the hopper and the bushing 218 receive upward force. Since the coupling force between the parts 218 can be firmly maintained, it is possible to prevent deformation due to the levitation of the screw 230 .

A hole is formed inside the bushing part 218 in an open top and bottom form, and the power transmission part 219 is inserted. When the screw 230 rotates in a state in which the upper rotation shaft 233 of the screw 230 is inserted into the power transmission unit 219, the power transmission unit 219 inserted inside the bushing unit 218 is the bushing unit 218 . ) because it rotates inside, it is preferable that the bushing part 218 is made of a material that is not easily deformed by friction generated when the power transmission part 219 rotates.

The power transmission unit 219 may include a coupling unit 2191 and an upper protrusion 2195 . The outer surface of the coupling part 2191 is also formed in the shape of a cone whose radius decreases toward the top so as to correspond to the shape of the inner surface of the bushing part 218 that is formed in a cone shape with a radius decreasing toward the top. A shaft hole 2192 into which the upper rotation shaft 233 of the screw 230 is inserted is formed in the coupling part 2191 . The upper rotation shaft 233 of the screw 230 may be formed as a prismatic shaft, and the shaft hole 2192 may be formed as a prismatic shaft hole. In the present embodiment, the upper rotation shaft 233 of the screw 230 is formed as a hexagonal shaft, and the shaft hole 2192 is formed as a 12-angle shaft hole 2192 that is twice as large. 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 rotation shaft 233 of the screw 230, but if it is formed as a shaft hole with 12 angles, which is a double The coupling between the screw 230 and the upper rotating shaft 233 and the power transmission unit 219 may be more easily achieved. Furthermore, by forming an inclined surface in which the size of the shaft hole is expanded at the entrance of the shaft hole of the 12 angles, it is possible to further facilitate the coupling. Accordingly, when the upper rotational shaft 233 of the screw 230 is formed as an n-shaped prismatic shaft in order to facilitate coupling between the two members, the shaft hole formed in the coupling portion 2191 of the power transmission unit 219 is It can be formed with a 2n square shaft 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 hopper 210 .

An upper protrusion 2195 is formed on the upper portion of the coupling portion 2191, and when the power transmission unit 219 is inserted into the bushing portion 218 from the bottom surface of the hopper housing 215, the upper protrusion 2195 is the bushing portion ( It protrudes above the upper surface of the bushing part 218 through the hole of 218 and is located inside the hopper 210 . At this time, the upper protrusion 2195 is formed in a quadrangular shape, and a prismatic groove 2251 is formed on the bottom surface of the cut part 225 in a corresponding shape to couple the cut part 225 to the upper protrusion 2195. have. The shape of the upper protrusion 2195 and the shape of the groove 2251 on the bottom surface of the cut part 225 corresponding thereto are not limited thereto, and may be variously modified, such as a cross shape, a spline shape, and the like.

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

A step is formed at the upper end of the shaft hole 2192 formed on the inner surface of the coupling portion 2191 to limit the insertion depth of the upper rotary shaft 233 of the screw 230, and the screw 2199 head is at the top based on the step. will be located

As described above, as the inner surface of the bushing unit 218 and the outer surface of the power transmission unit 219 are in contact with each other in the form of a cone whose radius decreases toward the top, respectively, when the screw 230 receives a lifting force In order to prevent injury of the screw 230 . Furthermore, as the power transmitting unit 219 receives a force to face upward, the power transmitting unit 219 and the bushing unit 218 are more concentrically positioned, so that 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 part 225 may be driven by including a hook-type cutting edge 226 and a horizontal cutting edge 227 . At this time, the hook-type cutting edge 226 and the horizontal cutting edge 227 may be integrally formed.

The hook-type cutting edge 226 is formed to extend upwardly in the form of a spiral in the rotational direction of the cutting part 225 from the rotational center. The upper end of the hook-type cutting edge 226 is preferably formed in the form of a sharp hook as the cross section becomes smaller toward the end. The hook-type cutting edge 226 is not formed in a plate shape, but is formed to have a predetermined flesh thickness, and has a smaller cross section as it goes upward, and is curved in a spiral and extended upward, so it is formed in the form of a cone.

The hook-type cutting edge 226 facing upward in the shape of a hook mainly plays a role of crushing the juice material input to the upper portion. In addition, since the hook-type cutting edge 226 is formed not in a plate shape but in a shape having a predetermined flesh thickness, it is possible to prevent a phenomenon in which stem vegetables such as water parsley are wound around the hook-type cutting edge 226 . In addition, the shape extending spirally into a cone shape serves to induce the cut juice material to move downward. At this time, the radially inner surface of the hook-type cutting edge 226 is formed with an inclined curved surface 2261 toward the radially outward as it goes downward, so that the hook-type cutting edge 226 rotates and the hook-type cutting edge 226 is rotated. ) so that the juice material crushed by the

As the height of the upper end of the hook-type cutting edge 226 increases, the crushing effect increases. In addition, it is preferable that the radial length of the hook-type cutting edge 226 is formed as long as possible in the radial direction in a 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 lower surface of the hopper 210 . The horizontal cutting edge 227 is preferably formed to have a predetermined thickness even in the vertical direction. As shown, a blade is formed at the top where the inclined surfaces of the front and rear surfaces of the horizontal cutting edge 227 meet in the rotation direction. At this time, as shown in FIG. 13 , the end of the horizontal cutting edge 227 may be formed such that the height thereof is gradually reduced. The horizontal cutting edge 227 serves to secondarily crush the juice material that has been crushed by the hook-type cutting edge 226 by the blade formed at the top and has moved downward, and the horizontal cutting edge 227 is As it is formed to have a thickness, the juice material located on the bottom surface of the hopper 210 is pushed so that it can be smoothly discharged through the discharge hole 217 . This is because if the thickness of the horizontal cutting edge 227 is thin, the hopper 210 may not be able to push the juice material located on the bottom surface and a phenomenon may occur in vain.

The horizontal cutting edge 227 is preferably formed to extend at a position 180 degrees opposite to the direction in which the hook-type cutting edge 226 extends from the center of rotation of the cutting part 225 , but is not limited thereto. At this time, it is preferable that the horizontal cutting edge 227 is curved in a direction opposite to the rotation direction of the cutting part 225 .

It is preferable that the horizontal cutting edge 227 is also formed as long as possible in the radial direction in a range in which interference with the inner surface of the hopper 210 does not occur, similarly to the hook-type cutting edge 226 .

A bottom surface groove 2271 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 cut portion 225 .

As described above, in the center of rotation of the lower surface of the cut portion 225, a prismatic groove 2251 may be formed to correspond to the shape of the upper protrusion 2195 of the power transmission unit 219 formed in a square prismatic shape, and the prismatic groove ( 2251) is formed on the screw groove 2252 to which the screw is fastened. By fastening the cut portion 225 using a screw 2199 in a state in which the square groove 2251 is inserted into the upper protrusion 2195 of the power transmission unit 219, the cut portion on the inner bottom surface of the hopper housing 215 (225) may be rotatably mounted.

On the inner surface of the hopper 210, at least one first inner protrusion 2155 that is formed to protrude inwardly in the vertical direction may be formed at least one or more as shown in FIG. 9 . The first inner protrusion 2155 interacts with the hook-type cutting edge 226, and the juice material injected into the hopper 210 is caught by the first inner protrusion 2155 and serves to hold the hook-type cutting edge ( 226) to improve the crushing efficiency. If there is no first inner protrusion 2155 , the juice material rotates together with the hook-type cutting edge 226 and is not cut may occur. However, by rotating the hook-type cutting edge 226 in a state in which the juice material is supported in the rotational direction by the first inner protrusion 2155, the juice material can be easily crushed. Therefore, the first inner protrusion 2155 is preferably formed to have a relatively large height protruding inward compared to the second inner protrusion 2157 to be described later so as to support the juice material in the radial direction.

One side of the outer circumferential surface of the hopper 210 is recessed into the inside by the aforementioned interference prevention groove 2154. As shown, a first inner protrusion 2155 may be formed together with the interference prevention groove 2154 as shown.

At this time, the lower end of the inner protrusion is preferably formed so as to be positioned at the upper end of the hook-type cutting edge 226, the lower end of the first inner protrusion 2155 as shown in FIG. Through-groove 2156 penetrating both sides may be formed in the shape of the upper end of the hook-type cutting edge 226 so that the upper end of the blade 226 can pass therethrough. By forming the lower end of the first inner protrusion 2155 in this way, the lower end of the first inner protrusion 2155 and the upper end of the hook-type cutting edge 226 can be positioned at a position where they overlap each other. At the same time, the radial length of the hook-shaped cutting edge 226 can be made larger, so that the cutting efficiency can be increased.

In addition, at least one second inner protrusion 2157 protruding radially inwardly from the upper portion of the position where the end of the horizontal cutting edge 227 is located may be formed on the inner surface of the hopper 210 . 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 and introduced into the discharge hole 217 as the horizontal cutting edge 227 rotates, and a portion is gradually moved radially outward by centrifugal force. At this time, the juice material located on the upper part of the horizontal cutting edge 227 may not flow into the discharge hole 217 and may cause a problem of spinning together in the upper part of the horizontal cutting edge 227 . At this time, the juice material pushed out of the upper portion of the horizontal cutting edge 227 by centrifugal force may collide with the second inner protrusion 2157 and may be separated from the horizontal cutting edge 227 .

In this embodiment, the second inner protrusion 2157 is formed under the first inner protrusion 2155 . In addition, a discharge hole 217 is formed vertically below the first inner protrusion 2155 and the second inner protrusion 2157 , and is cut through the first inner protrusion 2155 and the second inner protrusion 2157 and separated. It allows the juice material to fall vertically down and be directly supplied into the juice drum 280 through the discharge hole 217 .

Hereinafter, the screw 230, the juice separation drum 260, and the juicer drum 280 constituting the juicer 200 and positioned under the hopper 210 will be described. First, the screw 230 will be first described 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 a bottom surface of the screw shown in Fig. 16, and Fig. 19 is shown in Figs. This is a modification of the screw.

The screw 230 is mounted inside the juice separation drum 260 and receives rotational force from the drive shaft 130 of the main body 100 to perform a rotational motion, and compresses and pulverizes 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 shape from an outer surface of the screw body 231 .

As illustrated, the screw body 231 may be divided into upper and lower portions around a portion having the largest radius of the screw body 231 . At this time, the upper portion forms a cutting section for additionally cutting the juice material input from the hopper 210, and the lower portion forms a juice section for generating juice by squeezing the juice material in earnest under the cutting section.

The lower portion of the screw body 231 is formed to have a gradually smaller radius as it goes down, and by making the radius smaller as it goes down, it is possible to form a space in which the residue separated by the juice is located. However, the lower shape of the screw body 231 is not limited thereto, and, for example, may be formed in a straight line downward without a change in radius.

In addition, the upper portion of the screw body 231 is formed to have a gradually smaller radius as it goes upward. As shown, the radius of change according to the height change is larger than that of the lower portion of the screw body 231 . The tip of the screw body 231 has the smallest radius and is formed to gradually increase in radius as it goes down. According to such a shape, a large material can be transported while gradually decreasing in size by compression and pulverization. to form space. In other words, since the diameter of the upper part of the screw body 231 is gradually increased as it goes down, the size of the space in which the material formed by the screw body 231 together with the screw thread 232 is transported gradually increases along the feeding direction of the material. becomes smaller as That is, by the rotation of the screw 230, the material is compressed and pulverized so that its size is gradually reduced and moves downward the screw 230 along the transport space that is gradually reduced along the screw thread 232 formed in the downward direction. it will be 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 , and the juice target is squeezed into a narrow gap between the screw 230 and the juice separation drum 260 by the screw thread 232 . and transported downwards. At this time, it is preferable that the screw thread 232 protrudes so as to be in contact with or close to the juice separation drum 260 . As described above, the upper portion of the screw body 231 has a smaller radius as it goes upward, and thus the protrusion height of the screw thread 232 increases toward the upper portion of the screw body 231 .

The screw thread 232 may be formed in one or a plurality, in the present invention, any one of the plurality of screw threads 232 (the first screw thread 232-1) is the upper end of the screw body 231 . A single-edged screw 230 that is formed to extend to form a single-edged 2321 at the upper end of the screw body 231 may be used. When a double-edged screw in which two screw threads extend symmetrically to the upper end of the screw body 231 is used, a large load is applied, so the single-edged screw 230 is used in the present invention, but is not necessarily limited thereto.

At this time, in the present invention, the radius of the outer blade 2321 of the upper end of the screw body 231 may be formed to protrude outward to be larger than the longest radius of the screw body 231 . In this way, in a state where the size of the screw body 231 is maintained as before, the radius size of the single blade 2321 is formed to be larger than the longest radius of the screw body 231, thereby securing a wider space in which the juice material is put in the upper part. can do This allows the juice material subdivided in the upper hopper 210 to be more smoothly introduced into the screw 230 .

As shown, a second screw thread 232-2 that is spirally formed starting from the upper portion of the screw body 231, which is a juice section, may be formed, and the first screw of the lower portion of the screw body 231 is formed. Another plurality of third screw threads 232-3 may be formed between the threads 232-1 and the second screw threads 232-2. Accordingly, the width between the adjacent screw threads 232 formed in the screw body 231 is formed to have a relatively wide interval at the upper portion of the screw body 231 , and a plurality of screws in the lower portion of the screw body 231 . It is formed to have a relatively narrow interval by the screw thread (232). That is, in the cutting section, which is the upper part of the screw 230 , the function of crushing a large-sized juice target is mainly performed, and in the juice section, which is the lower part of the screw 230 , the function of juicing is performed by crushing and pressing by the rotation of the screw 230 . can be mainly performed.

In addition, a plurality of residue guide jaws 235 protruding outside the radius of the lower end of the screw body 231 may be formed in a circumferential direction. The residue guide jaw 235 performs a function of sweeping down the residues transferred to the bottom of the juice separation drum 260 by being separated by the juice when the screw 230 rotates. As described above, by smoothly removing the residues caught under the juice separation drum 260 by the residue guide jaws 235 formed on the radial outer peripheral surface of the lower end of the screw 230, it is possible to further increase the juice extraction efficiency.

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

In addition, the screw 230 lower rotation shaft 234 protruding downward from the hollow inside of the screw body 231 is formed as a prismatic shaft hole and inserted into the prismatic driving shaft 130 protruding from the upper portion of the body 100 . to receive power from the motor 1001 . As described in the coupling structure between the screw 230, the upper rotary shaft 233 and the power transmission unit 219, the drive shaft 130 is formed as an n-angle prismatic axis, and the screw 230, the lower rotary shaft 234 is positioned at a 2n angle. It is also possible to facilitate the coupling between the two members by forming a prismatic shaft hole. For example, when the drive shaft 130 is formed as a hexagonal shaft, the lower rotation shaft 234 of the screw 230 may be formed as a 12-angled shaft hole.

A gripping part 236 may be formed at an upper end of the screw body 231 . The gripper 236 may be formed to protrude from the top of the screw body 231 with a single blade 2321 at a predetermined horizontal angle, which is a user using the screw 230 mounted in the juice drum 280 for reasons such as washing. This is so that it can be easily pulled out by holding it together with the single blade 2321.

19 shows a modified example of the screw 230 described above, in this embodiment, between the cutting section and the juice section, in the form of a circular ring or a belt at the boundary between the upper and lower parts of the screw 230 An over-injection prevention rib 239 protruding to a predetermined thickness from the screw body 231 along the circumferential direction is formed.

The over-injection prevention rib 239 is to prevent 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 once. The gap between the screw 230 and the juice separation drum 260 is reduced by the over-injection prevention rib 239 , and thus it is possible to prevent a large amount of juice material from being injected into the space therebetween.

Since the configuration of the remaining 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 an embodiment of the present invention will be described in more detail with reference to FIGS. 20 to 21 .

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

As shown, the juice separation drum 260 according to the present invention may be configured by a combination of the inner module 240 and the 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 elongated in the vertical direction by the plurality of inner plate portions 241.

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

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

In addition, the first rib tuck 244 may be formed to protrude long along the vertical direction on the inner peripheral surface of the inner module 240 . The first rib tuck 244 allows the material to be compressed or crushed by interaction with the screw thread 232 according to the rotation of the screw 230 . If the first rib tuck 244 is not present, the juice target does not go down and is stagnant, or the compression or crushing force is low or may not occur. In this case, the first rib tuck 244 may be formed on one side of the slit 242 of the inner module.

In addition, a predetermined number of second rib tucks 243 protruding long in the vertical direction may be formed on the inner surface of the inner module 240 . The second rib tuck 243 transfers the juice material input into the inside of the juice separation drum 260 to the lower portion and performs a function of crushing the juice target. The second rib tuck 243 may perform a function of reinforcing the rigidity of the inner module 240 , and may perform a function of guiding a juice target 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 protrusion height of the second rib tuck 243 may be formed to have the same height from the upper part to the lower part of the inner module 240 , but is preferably formed in a form that gradually decreases from the upper part to the lower part of the inner module 240 . can be In addition, the second rib tuck 243 is formed to be inclined downward from the upper part of the inner module 240 to the lower part, and protrudes toward the screw 230 in the middle portion thereof to form a stepped stepped part 2431 . 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 tucks 243 may be variously changed as necessary in consideration of design conditions and efficiency of juicing. In the embodiment of the present invention, the formation direction of the second rib tuck 243 has been 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 tuck 244 is formed on the lower inner surface of the inner plate part 241 (in more detail, one side of the slit 242 ), and the second rib rib 243 is the inner surface of the inner plate part 241 . It is formed as a whole from the upper part to the lower part.

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

In addition, a material inflow guide part 246 that is a curved part gradually inwardly along the rotation direction of the screw 230 may be formed on one side of the extension part 245 . If there is no material inlet guide part 246, the juice material does not flow down and there may be a problem of spinning together with the single blade 2321 on the extension part 245. When the juice material rotates with the single blade 2321 In contact with the material inflow guide portion 246, it can be induced to move downward away from the single blade 2321. Furthermore, it is possible to solve the problem of material being caught in the material inlet guide part 246 as it is formed as a soft inclined surface. The upper surface of the material inlet guide part 246 is formed so as not to interfere with the lower surface of the single blade 2321 .

A predetermined number of fitting protrusions 247 are formed on the lower surface of the inner module 240 , and when coupling between the inner module 240 and the outer module 250 , the fitting protrusions 247 are formed on the outer module 250 . ) is inserted into the fitting groove 258 formed on the bottom surface, thereby coupling between the two members 240 and 250 .

Next, the outer module 250 will be described. The outer module 250 is generally cylindrical in shape and includes an outer plate part 251 having open upper and lower sides and a rib 252 protruding from the inner surface of the outer plate part 251 .

The outer plate part 251 accommodates the inner module 240 therein, so that the outer module 250 and the inner module 240 may be detachably coupled. That is, the outer module 250 may be coupled to receive and surround the inner module 240 when combined with the inner module 240 . In this case, the outer module 250 may surround and support the inner module 240 .

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

As such, in this embodiment, the slit 242 of the inner module 240 and the rib 252 of the outer module 250 are combined to discharge the 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 slit 242 described above, and the width of the rib 252 is narrower toward the upper side so that the width of the upper rib 252 is that of the lower side. It may be smaller than the width of the rib 252 .

When the outer module 250 and the inner module 240 are vertically moved and coupled by the shape of the rib 252 and the slit 242 as described above, the lower portion of the relatively wide slit 242 is relatively wide. By inserting the upper part of the small rib 252, the outer module 250 and the inner module 240 can be easily coupled.

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

In this way, the juice formed inside the juice separation drum 260 formed by the combination of the inner module 240 and the outer module 250 is the slit 242 of the inner module 240 and the rib 252 of the outer module 250 . ) may be discharged to the outside of the juice separation drum 260 through a slit hole formed between the slit hole and 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 so that the width of the gap gradually increases 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 slit 242 is gradually increased in the radial direction.

Further, in the longitudinal direction, the width of the gap is made smaller as it goes down, so that the residue generated by being pulverized more finely toward the bottom is prevented from being discharged through the gap, and strong pressure by the screw 230 is applied. It is preferable to support it.

At the upper end of the outer module 250, a predetermined number of drum fixing parts 259 protruding in the horizontal direction are formed, which are inserted into the drum fixing groove 2802 formed on the upper part of the juice drum 280 to be described later to the juice drum ( It is possible to fix the position of the juice separation drum 260 in the 280).

In addition, a predetermined number of fitting grooves 258 are formed in the lower surface of the outer module 250, and when coupling between the inner module 240 and the outer module 250, the fitting protrusion 247 is the outer module. It is inserted into the fitting groove 258 formed on the bottom surface of the 250, to couple between the inner module 240 and the outer module (250).

In this embodiment, a juice separation drum 260 that forms an outlet hole by the combination of the inner module 240 and the outer module 250 is used, but a mesh drum in which a plurality of circular mesh holes are formed on the conventionally well-known drum surface. is free to use In addition, in this embodiment, the rib 252 is formed in the outer module 250 and the slit 242 is formed in the inner module 240 to discharge the juice when the inner module 240 and the outer module 250 are combined. However, without forming a separate outer module 250, the above-mentioned rib 252 is formed on the inner surface of the juice drum 280 and the juice is discharged by inserting the inner module 240. An outflow hole may be formed.

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

23 is a partially cut-away perspective view of the juice drum shown in FIG. 4, FIG. 24 is a perspective view of the juice drum showing an open state of the juice stopper in FIG. 23, and FIG. 25 is a rear view of the juice stopper shown in FIG.

In the present invention, as shown, a double packing that is fixed between the upper and lower surfaces of the upper part of the waterproof cylinder 281 and packs the upper and lower surfaces together may be used.

At the outer lower end of the juice drum 280 , the juice outlet 285 through which juice is discharged and the residue outlet 284 through which the residue is discharged may be disposed at positions spaced apart from each other.

A plurality of binding protrusions 2801 are formed on the inner side edge of the upper portion of the juice drum 280, and the coupling protrusions 2174 formed on the outer edge of the lower end of the hopper housing 215 are positioned between the binding protrusions 2801. and by rotating the hopper 210 by pressing it slightly downward, the coupling protrusion 2174 is positioned below the binding protrusion 2801 to couple the juice drum 280 and the hopper 210 . At this time, the binding protrusion 2801 has a rotation preventing protrusion 2803 at the end in the fastening direction to prevent further rotation of the coupling protrusion 2174 to maintain the binding between the two members 210 and 280 .

In addition, when the coupling protrusion 2174 of the hopper 210 is positioned in the space between the two adjacent binding protrusions 2801, the space between the two binding protrusions 2801 is so that the coupling protrusion 2174 can sufficiently move left and right. It is preferable to secure it widely. As described above, in the present invention, since the screw 230, the lower rotation shaft 234 is composed of an n-shaped prismatic shaft, and the shaft hole of the power transmission unit 219 is composed of a 2n-shaped prismatic shaft hole, the user can use the hopper 210 This is to secure a rotational space so as to hold and rotate the screw 230 and a position for inserting the power transmission unit 219 into the lower rotating shaft 234 .

The juice packing 287 on the bottom surface of the juice drum 280 may be fixed so that one end is fixed and the other end can freely rotate. The residue packing 287 closes the residue discharge hole 2806 when no external force is applied from the inside of the juice separation drum 260 to the outside, and elastically deforms to open the residue discharge hole 2806 when an external force is applied. do. Accordingly, the residue inside the juice separation drum 260 reaches the bottom surface of the juice drum 280 and pushes the residue packing 287 to be discharged through the residue outlet 284 .

At this time, in the present invention, the residue outlet 284 may be formed in a structure that is opened and closed by rotation, rather than being fixed to one side of the juice drum 280 .

As shown, the portion forming the upper end of the residue discharge hole 2806 and the residue discharge port 284 to which the residue packing 287 is fixed is integrally formed with the juice drum 280 body 100, and the residue discharge port ( 284) is hinged rotatably to the bottom surface of the juicing drum 280, the residue outlet lower end forming the lower end (2842). A packing ring 2844 is mounted on the upper surface of the lower end of the waste outlet 2842 to surround the waste outlet 2806 to prevent juice or debris from leaking to the outside. A 'C'-shaped fixing ring 2843 is rotatably coupled to one end of the lower end of the waste outlet 2842 .

When the juice portion 200 is coupled to the main body 100, the rotation prevention key 112 is inserted into the rotation prevention key groove 2159 and is coupled. Therefore, it is possible to fix the circumferential position of the juicer 200 by the coupling structure of the rotation prevention key groove 2159 and the rotation prevention key 112 . In addition, when the screw 230 rotates in reverse, the binding between the juice drum 280 and the hopper 210 may be released, and the rotation of the hopper 210 is blocked by the coupling structure to prevent this.

As described above, in the present invention, for the safety of the user, it is not possible to bind the hopper 210 to the upper portion of the juice drum 280 in a state where only the juice drum 280 is seated on the body 100, and the juice drum 280 The juicer 200 may be coupled to the body 100 only in a state in which the hopper 210 is bound.

The second magnet 1102 forms a magnetic force with the first magnet 2211 fixed to the magnet arrangement part 221 of the lid part 220 described above. When the lid part 220 is opened and closed, as the magnet arrangement part 221 rotates, the magnetic force between the first magnet 2211 and the second magnet 1102 (the first magnet 2211 and the second magnet 1102) Depending on the polarity, attractive or repulsive force) is changed. As the magnetic force changes, the position of the second magnet 1102 is changed. Accordingly, the rotation bar 1151 moves according to the change in the position of the second magnet 1102 , so that the sensor unit in the opening/closing sensing unit 115 detects the opening/closing state of the lid unit 220 .

When the lid part 220 is opened, the power supply to the motor 1001 is cut off to prevent rotation of the screw 230 .

The drive shaft 130 is protruded from the upper surface of the lower body 120 , and the lower rotation shaft 234 of the screw 230 can be directly coupled to the drive shaft 130 , but in the present invention, the drive shaft 130 and the screw (230) A flow drive shaft is used to automatically couple between the lower rotary shafts 234. Hereinafter, the configuration of the flow drive shaft will be described in detail.
