The drum housing 200 houses the separation screw 600 therein and the driving motor (not shown) of the main body 1 is transmitted to the separation screw 600 through a driving shaft (not shown). The driving motor includes a speed reducer (not shown), and the speed reducer decelerates the rotational speed of the driving motor (about 1800 rpm), and the separating screw 600 rotates at a low speed (about 80 rpm or less). This makes juice possible without destroying nutrients. Generally, a juicer having such an arrangement structure is referred to as a vertical low-speed juicer.

2A and 2B are exploded perspective views of a configuration in which a body portion is omitted from the juicer according to the embodiment shown in Figs. 1A and 1B of the present invention. As shown in FIGS. 2A and 2B, the hopper 100 is adapted to feed a juice object (for example, vegetables, grains, fruits, etc.) into the hopper 100 and to feed the juice object into the drum housing 200 Guide.

The drum housing 200 is formed in a cylindrical shape having an open top, and a screw 300 may be disposed therein. The juice outlet 220 and the debris outlet 230 are formed in the lower portion of the drum housing 200.

The juice outlet 220 can be opened or closed by the juice opening and closing mechanism 240 and the juice outlet 230 can be opened or closed by the dirt opening and closing mechanism 250.

The drum housing 200 has a hollow cylindrical or truncated conical shape and can be squeezed or crushed by interaction with the screw 300. A drum hole 270 is formed in the lower center of the drum housing 200. The drive shaft may be inserted into the drum hole 270 and connected to the screw 300 to transmit power to the screw 300. The inner circumferential surface of the drum hole 270 may have a shape corresponding to the shape of the drive shaft so that the drive shaft can be inserted.

The screw (300) is rotatably received by receiving a rotational force from a drive shaft, and presses or crushes a juice object. At least one first spiral protrusion 310 is formed on the outer circumferential surface of the screw 300 so that the juice object can contact the drum housing 200. The object to be juiced is conveyed to the lower part by the first screw projections 310 and the juice object is pressed by the narrow gap between the screw 300 and the juice drum 200. [ The spacing between adjacent first helical projections 310 formed on the top of the screw 300 may be greater than the spacing between neighboring first helical projections 310 formed below the screw 300. [

The upper portion of the screw 300 is inserted into a shaft hole (not shown) formed in the lower surface of the hopper 100 so that the screw 300 can be rotated in both upper and lower directions of the shaft. Accordingly, the vibration of the screw and the wear of the apparatus can be prevented, and the noise generated when the screw hits the inner wall of the drum housing 200 can be reduced.

First, referring to FIGS. 2A and 2B, FIG. A separating screw 600 is disposed inside the drum housing 200 and the hopper 100 can be detachably coupled to the drum housing 200.

(E.g., vegetable, cereal, fruit, etc.) is guided to the drum housing 200 through the hopper 100. [

The drum housing 200 is formed in a cylindrical shape with an open top, and a separation screw 600 may be disposed therein.

In the lower part of the drum housing 200, an juice outlet 220 for discharging juice and a juice outlet 230 for discharging the juice are formed. The juice is separated into the residue and the juice by the drum housing 200 and the separation screw 600 and the residue is left on the radially outer side of the separation screw 600 and the juice is moved radially inward of the separation screw 600 do. Thereafter, the debris is discharged through the debris discharge port 230, and the juice is discharged through the juice discharge port 220 through a path different from the path through which the debris is discharged.

A drum hole 270 is formed in the lower center of the drum housing 200. The drive shaft may be inserted into the drum hole 270 to transmit power to the separation screw 600. The inner circumferential surface of the drum hole 270 may have a shape corresponding to the shape of the drive shaft so that the drive shaft can be inserted.

The first rib jaw 250 and the second rib jaw 260 may be formed on the inner circumferential surface of the drum housing 200 along the circumferential direction. The first rib jaw 250 and the second rib jaw 260 may be formed to be inclined at an acute angle in the longitudinal direction or the longitudinal direction. The material can be squeezed or crushed by the interaction of the spiral projections 613 and 629 and the first and second rib jaws 250 and 260 as the separation screw 600 rotates. The second rib jaw 260 may further perform a function of guiding the object to be juiced to the lower portion of the drum housing 200. In addition, the second rib jaw 260 may function to adjust the position of the separation screw 600 and adjust the juice space in addition to the function of crushing and crushing the material.

The second rib jaw 260 may be formed in the longitudinal direction of the drum housing 200 and the first rib jaw 250 may be formed only in a part of the length of the drum housing 200. That is, the length of the second rib jaw 260 may be longer than the length of the first rib jaw 250.

If there is no such rib jaws 250 and 260, the juice object may not go down and become stagnant, or the pressing force or grinding force may be low or not. Also, the rib jaws 250 and 260 can prevent deformation of the drum housing 200, which may be caused by a compressive force generated when the material is conveyed and crushed by the spiral of the separation screw 600.

Generally, the rib jaws 250 and 260 serve to allow the material to be inserted into the drum housing 200 downward at a narrow portion where the material abuts against the screw 600. The rib jaws 250 and 260 can function to squeeze and squeeze the material together with the screw 600 while lowering the material down. The rib jaws 250 and 260 do not have to be formed in the longitudinal direction of the drum housing 200 but are formed so as to intersect with the spirals 613 and 629 of the screw 600, But may also be implemented in inclined form with a constant slope with respect to.

The second rib jaw 260 is formed long in the longitudinal direction on the inner circumferential surface of the drum housing 200 so as to guide and press the material and to transfer and press the material by the screw of the screw 600 A reinforcing function for preventing deformation of the drum housing 200 due to the pressing force generated, and a function of adjusting the receiving position of the screw 600 in the drum housing 200 and adjusting the juice space.

The protrusion height of the second rib jaw 260 may be configured to have the same height from the upper portion to the lower portion, but may be gradually lowered from the upper portion to the lower portion, or at least one Or more may be formed. The protrusion height of the upper portion of the second rib jaw 260 may be lower than the protrusion height of the lower portion of the second rib jaw 260. [

The separation screw 600 receives rotational force from the drive shaft and rotates, and presses or crushes the juice object.

Next, an embodiment of a separating screw which can be applied to Figs. 2A and 2B will be described with reference to Figs. 3A and 3B.

The separation screw 600 according to embodiments of the present invention includes a first module 610 and a second module 620 in two cylindrical shapes. A first spiral projection 613 (hereinafter also referred to as a "screw spiral") is formed obliquely with respect to the longitudinal direction on the outer peripheral surface of the hollow first module 610, and a plurality of slits 615 extend in the longitudinal direction . In this embodiment, the plate member in which the slit 615 is not formed in the first module 610 is referred to as a rod 614. [ A plurality of ribs protruding from the outer circumferential surface of the cylindrical second module 620 are formed in a shape corresponding to the slit 615. In this specification, a rib formed on the outer peripheral surface of the second module 620 is referred to as a rib 621. [

At this time, a second helical projection 629 (hereinafter also referred to as a "screw spiral") may be formed on the outer peripheral surface of the rib 621. Depending on the shape of the screw thread and the position of the rib 621, the second helical projection 629 may not be formed on the outer peripheral surface of the part of the rib 621.

When the first module 610 and the second module 620 are coupled to each other, the first module 610 has an inner diameter larger than the outer diameter of the second module 620, A predetermined gap is formed between the slit 615 and the rib 621 while the rib 621 of the second module 620 is inserted into the slit 615 of the first module 610. [ The juice flows into the separating screw 600 through the gap and the separated juice separated at the lower part between the separating screw 600 and the drum housing 200 can be collected and discharged to the outside.

In an embodiment of the present invention, when the first module 610 and the second module 620 are coupled, a screw thread formed on the outer peripheral surface of the separating screw 600 is continuously formed. In other embodiments, some of the sections may be cut off to some extent, but generally form a continuous screw helix. For this, the diameter of the rod 614 and the diameter of the rib 621 are the same, and the projecting heights of the screw spiral protrusions 613 and 629 may be equal to each other.

On the other hand, the width of the rod 614 can be made narrower toward the radial center. In this case, the gap formed between the slit 615 of the first module 610 of the separation screw 600 and the rib 621 of the second module 620 becomes wider toward the radial center, It is possible to prevent the above-mentioned gap from being clogged or disturbing the flow of the juice due to the scum. In one aspect, the cross-section of the rod 614 of the first module 610 may be generally semicircular, elliptical, or trapezoidal in order to narrow the width of the rod 614 toward the radial center of reflections.

On the other hand, the second module 620 of the separation screw 600 has a plurality of screw grooves 622 formed between the plurality of ribs 621. In one aspect, the screw groove 622 may be in the form of an entirely enclosed inner circumferential surface. In another aspect, the screw groove 622 may be in the form of a part of the inner circumferential surface thereof, particularly, the lower inner circumferential surface of the screw groove 622 being open. A clearance may be formed between the inner circumferential surface of the screw groove 622 and the inner circumferential surface of the rod 614. Through which the juice can move downwardly between the first module 610 and the second module 620. A juice discharge hole 628 may be formed on the lower side of the screw groove 622. The juice collected at the lower part between the first module 610 and the second module 620 can be introduced into the inside of the separation screw 600 through the juice discharge hole 628. [ Meanwhile, the lower inner circumferential surface of the screw groove 622 may be opened so that the opened inner circumferential surface may serve as the juice discharge hole 628.

An axial through hole 630 through which the screw shaft 611 is inserted may be formed on the upper surface 627 of the second module 620. The shaft through hole 630 may be a square hole in order to fix the coupling position of the first module 610 and the second module 620 and prevent relative rotation of the first module 610 and the second module 620 . 13A to 16 illustrate that the axial through hole 630 is rectangular, but the shape of the axial through hole 630 is not limited to the illustrated one. In this specification, the first module 610 and the second module 620 can be fixed at four different positions by the screw shaft 611, which is a square shaft, and the shaft hole 630, which is a square hole, .

A seating groove 625 may be formed on the lower side of the second module 620 so that the separation screw 600 can be seated in the drum housing 200. A seating protrusion (not shown) corresponding to the seating groove 625 may protrude upward from a lower surface of the drum housing 200. By joining the seating groove 625 so as to surround the seating protrusion, it is possible to prevent the debris separated during the juicing process from flowing into the screw 600.

A gap is formed between the inner circumferential surface of the screw groove 622 and the inner circumferential surface of the rod 614 (that is, between the inner circumferential surface of the first module 610 and the outer circumferential surface of the second module 620) . The clearance may become wider toward the lower side of the separation screw 600. The clearance can be ensured in a space in which the coolant can flow and flow between the first module 610 and the second module 620 through the clearance.

A first step 616 may be formed on the lower end of the rod 614 of the first module 610 and a second step 623 may be formed on the lower side of the rib 621. The second step 623 of the second module 620 and the first step 616 of the inner module 10 are coupled to each other to withstand the pressure transmitted to the screw 600 and to prevent the debris from entering the inside of the screw 600 Do not.

3A and 3B, an embodiment of the separation screw according to the present invention will be described in more detail. The separation screw 600 of the present invention may include a first module 610 and a second module 620. The first module 610 and the second module 620 may be detachably coupled.

A screw shaft 611 is disposed at an inner center of the first module 610. The screw shaft 611 is further projected from the upper surface of the separation screw 600 and can be inserted into a receiving hole formed in the bottom surface of the hopper 100.

A screw hole 612 is formed in the lower portion of the screw shaft 611 to receive the rotational force of the drive shaft.

At least one screw spiral 613 is formed on the outer circumferential surface of the first module 610 so as to be in contact with the drum housing 200.

The first module 610 has a plurality of rods 614 separated by a plurality of slits 615. The plurality of rods 614 may be formed on the entire length of the first module 610, but may be formed on only a part of the length of the first module 610. A plurality of slits 615 are formed by the plurality of bars 614. The plurality of rods 614 may include a rod 614 having a relatively narrow width and a rod 614 having a relatively wide width to fix the coupling position with the second module 620.

The width of the rod 614 may be narrowed toward the radially inner side of the first module 610. Accordingly, it is possible to prevent a problem that the gap is blocked by the residue during the juicing process or the flow of the juice is interrupted. For this purpose, the cross section of the rod 614 may be generally semicircular, elliptical, or trapezoidal.

A first step 616 may be formed below the rod 614. The second step 623 of the second module 620 and the first step 616 of the first module 610 can withstand the pressure delivered to the screw 600 and the debris flows into the screw 600 .

The second module 620 may be configured to be inserted into the first module 610. The second module 620 may be generally cylindrical in shape and open at its upper and lower sides.

The second module 620 includes a plurality of ribs 621 protruding radially outward and a plurality of screw grooves 622 formed by a plurality of ribs 621. A predetermined gap may be formed between the slit 615 and the rib 621 by inserting the rib 621 into the slit 615 between the bars 614. The juice flows into the radial direction of the separating screw 600 through the gap and the debris remains between the separating screw 600 and the drum housing 200. The residue left between the separation screw 600 and the juice drum 200 moves downward through the spacing space between the separation screw 300 and the drum housing 200.

A second helical projection 629 can be formed on the outer circumferential surface of the rib 621 so as to be in contact with the drum housing 200. The coupling position of the first module 610 and the second module 620 is adjusted so that the first screw projections 613 formed on the first module 610 and the second screw projections 629 formed on the second module 620 are aligned, Can be constant. That is, assuming that the angle formed between the reference point of the first module 610 and the reference point of the second module 620 along the circumferential direction is 0 degrees at the position where the first module 610 and the second module 620 are completely combined Only when the reference point of the first module 610 and the reference point of the second module 620 have an angle (for example, 90 degrees, 180 degrees, 270 degrees) set along the circumferential direction, And the second module 620 can be completely combined. At this time, the first screw projections 613 formed on the first module 610 and the second screw projections 629 formed on the second module 620 are matched (that is, continuous screw spiral is formed). In order to keep the coupling position of the first module 610 and the second module 620 constant, a space having a relatively narrow space between the plurality of ribs 621 and a space having a relatively large space are periodically As shown in FIG. A rod 614 having a relatively large width can be inserted into a space in which a space between the plurality of ribs 621 is relatively large. The first spiral protrusion 613 formed on the first module 610 and the second spiral protrusion 629 formed on the second module 620 when the first module 610 and the second module 620 are engaged, ) Are aligned so that the screw spiral can be continuously formed.

Alternatively, the second helical projections 629 may not be formed on the outer circumferential surface of the ribs 621. In this case, it is possible to achieve the same or similar juicing efficiency as compared with the case where the second helical projections 629 are formed on the outer circumferential surface of the ribs 621 by narrowly forming the ribs 621.

An annular flange 624 may be formed on the upper side of the rib 621. The flange 624 supports the gap between the plurality of ribs 621 to be fixed.

A seating groove 625 may be formed on the lower side of the second module 620 so that the separation screw 600 can be seated in the drum housing 200. A packing may be disposed in the seating groove 625. Accordingly, it is possible to prevent the debris from entering the inside of the separation screw 600 during the juicing process.

A clearance may be formed between the inner circumferential surface of the first module 610 and the outer circumferential surface of the second module 620. The clearance may become wider toward the lower side of the separation screw 600. As the clearance is formed, a space for flowing and flowing between the first module 610 and the second module 620 through the gap can be secured.

3A and 3B, the separating screw 600 may be formed with a magnet receiving portion 626 on the upper surface 627 of the second module 620. In this case, When the second module 620 is coupled to the first module 610, magnets are disposed in the magnet accommodating portion 626 so that the second module 620 and the first module 610 are not easily separated, The second module 620 can be fixedly coupled to the first module 610 by disposing a magnet or a magnetic body having an opposite polarity inside the first module 610. [

4A and 4B, a key projection 640 is formed on the bottom surface of the upper surface of the first module 610 to fix the engagement position of the first module 610 and the second module 620 And a key groove 645 into which the key projection 640 is inserted may be formed on the upper surface of the second module 620. Rotation of the first module 610 and tilting of the second module 620 can be restricted by fitting the key projection 640 into the key groove 645. [

As shown in FIGS. 5A and 5B, another second modified embodiment of the separation screw 600 may be formed with a first rod step 650 on the upper side of the rod 614. In addition, a second bar step 655 may be formed on the lower side of the rib 621. The size of the gap between the slit 615 and the rib 621 can be changed during the rotation of the separation screw 600 in the juicing process. During the juicing process, the size of the gap can be kept constant in the juicing process by the first rod step 650 and the second rod step 655. [

Also, as shown in FIGS. 6 to 6C, an inclined portion 618 may be formed to receive the edge adjacent to the slit 615 of the first module 610. When the inclined portion 618 is formed in this manner, the object to be juiced can be smoothly passed, and the residue can be prevented from entering the separation screw gap.

7 is a partial cross-sectional view of the separation screw coupled to the drum housing; The left side section of FIG. 7 is expressed in such a manner that the passage through which the filtered debris is drained after the juice is squeezed between the separation screw 600 and the drum housing 200 can be understood and the right side section is compressed into the inner space of the separation screw 600, This juice is evident in the juice discharge path.

A drum hole 270 is formed at the center of the inner bottom surface of the drum housing 200. And a waterproofing cylinder 280 which may include a packing 261 for waterproofing on the inner circumferential surface of the drum hole 270 and inserted into the inner central space of the separating screw 600 according to design needs. A guide tab 282 is formed around the drum hole 270 so that the lower ring 390 of the separating screw 600 can be seated. The guiding jaw 282 is formed at a predetermined height on the bottom surface of the drum housing 200 so as to be inserted into the inner circumferential surface of the lower ring 390 of the separation screw 600 and a guide groove 291 is formed on the upper surface of the guiding jaw 282 can do. In this way, while the juice drum is fixedly supported, it is prevented that the drive shaft interferes with the drive shaft.

The separation screw is pushed into the screw internal space and flows into the juice discharge groove 297 formed at the center of the bottom surface of the drum housing. The juice collected here can be discharged through the juice outlet (220). The juice storage part 281 may be a storage space formed by an annular guiding wall on the outer wall and a waterproofing cylinder 280 on the inner wall.

At the outer side of the juice discharge groove 297 in the radial direction, a droplet discharge groove 298 is formed. The debris discharge groove (198) communicates with the debris discharge port (230). That is, the residue other than the juice between the separation screw 600 and the drum housing 200 moves downward between the separation screw 600 and the inner peripheral surface of the drum housing 200 and flows along the residue discharge groove 289 And is discharged through the residue discharge port 230.

As described above, according to the present invention, the conventional network drum is eliminated, and the configuration is simple and the manufacturing cost can be reduced. Further, by removing the conventional network drum, the washing is simple and the juicing efficiency can be improved.

In addition, according to the present invention, the feed of the material by the juice screw is smooth during the pressing process, and the juicing efficiency is improved by the fine grinding and pressing of the material, so that the addition of the material can be facilitated.

In addition, by preventing the juice drum from being caught in the juice drum during the juicing process, the juice may not disturb the juice from which the juice is extracted.

Further, since the juice drum is formed of a rigid material, deformation such as slitting of the juice drum in the juicing process can be prevented.

In addition, according to the embodiment of the present invention, the two modules can be coupled vertically so that the assembly and disassembly of the two modules are easy and the washing is simple.

Moreover, it is possible to prevent the debris from being caught in the gap through which the juice is discharged, by being formed between the two modules through the inclined portion formed in the juice screw, and the juicing efficiency can be improved.
