Modification.

First, the structure of the detachable screw according to various embodiments of the present creation will be described in detail through Figs. 1a to 4b, and a juice extractor to which the detachable screw can be applied will be described.

The detachable screw 300 according to the embodiment of the present invention includes two cylindrical first modules 10 and a second module 20. A screw spiral protrusion 13 (hereinafter also referred to as a "screw spiral portion" for convenience) is obliquely formed with respect to the longitudinal direction on the outer peripheral surface of the hollow first module 10, and a plurality of first slits 15 are along the length The direction extends to form. In the present specification, the plate member in which the first slit 15 is not formed in the first module 10 is referred to as a first bar 14. A plurality of ribs are formed on the outer peripheral surface of the cylindrical second module 20, and the shape thereof corresponds to the first slits 15. In the present specification, the ribs formed on the outer peripheral surface of the second module 20 are referred to as second bars 21.

At this time, the screw spiral protrusion 29 may also be formed on the outer peripheral surface of the second rod 21 (in order For convenience, the following will also be referred to as "screw helix"). Depending on the shape of the screw helix portion and the position of the second rod 21, the screw spiral protrusion 29 may not be formed on the outer peripheral surface of the portion of the second rod 21.

When the first module 10 is combined with the second module 20, since the inner diameter of the first module 10 is larger than the outer diameter of the second module 20, the first module 10 is coupled to the second module 20 at this time. The second rod 21 of the second module 20 is inserted into the first slit 15 of the first module 10, and a predetermined gap is formed between the slit 15 and the second rod 21. The juice enters the inside of the detachable screw 300 through the slit, and the slag from which the juice is separated gathers to the lower portion between the detachable screw 300 and the juice rinsing barrel 200, and is then discharged outward.

When the first module 10 is combined with the second module 20, the screw spiral portion formed on the outer peripheral surface of the detachable screw 300 is continuously formed. Although some sections are somewhat intermittent, they generally form a continuous screw helix. For this reason, the diameter of the first rod 14 and the diameter of the second rod 21 may be the same, and the protruding heights of the screw spiral protrusions 13, 29 may be the same.

Further, as shown in FIGS. 1a and 1b, a plurality of first ribs 250 and second ribs 260 may be formed on the inner circumferential surface of the juice jug 200 in the circumferential direction. The second rib 260 is formed along the length direction of the juice jug 200, and the first rib 250 may be formed only on a portion of the length of the juicing bucket 200. That is, the length of the second rib 260 may be formed to be larger than the length of the first rib 250.

Without such ribs 250, 260, the juiced object does not go down and stagnate, or the pressing or pulverizing force is reduced or does not occur. Further, the ribs 250, 260 can prevent deformation of the juice jug 200 caused by the pressing force generated during the conveyance and pulverization of the material by the spiral portion of the detachable screw 300.

The function of the ribs 250, 260 is generally such that the material entering the interior of the juice jug 200 is clamped down the narrow portion adjacent the screw 300. The ribs 250, 260 can function to cause the material to go down and to crush the material together with the screw 300. Therefore, it is not necessary to form the ribs 250, 260 along the longitudinal direction of the juice extracting tub 200, and it is also possible to form a shape that intersects with the spiral portion 310 of the screw 300, that is, an inclined shape having a certain inclination with respect to the longitudinal direction, to effectively Conveying and pressing materials.

Further, since the second rib 260 is formed to extend in the longitudinal direction on the inner circumferential surface of the juice jug 200, not only the function of guiding and pressing materials but also the prevention of the material being conveyed and pressed by the spiral portion of the screw 300 can be exhibited. The resulting pressing force causes the reinforcing function of the deformation of the juice jug 200 and the function of adjusting the position of the screw 300 in the juicing barrel 200 and the juicing space.

Further, the protruding height of the second rib 260 may be formed to have the same height from top to bottom, or may be formed to gradually decrease from the top to the bottom or at least one step in the intermediate portion of the longitudinal direction of the second rib 260. The protruding height of the upper portion of the second rib 260 may be lower than the protruding height of the lower portion of the second rib 260 with reference to the step.

Further, the width of the first rod 14 may be substantially set to have a shape that is narrower toward the center in the radial direction. At this time, the gap formed between the first slit 15 of the first module 10 of the detachable screw 300 and the second rod 21 of the second module 20 is wider toward the center in the radial direction, thereby avoiding the squeeze The scum of the juice process causes the gap to be clogged or to hinder the flow of juice. In one embodiment, the first rod 14 of the first module 10 may be substantially semi-circular, elliptical or trapezoidal in cross section so that the width of the first rod 14 is narrower toward the center in the radial direction. .

On the other hand, the second module 20 of the detachable screw 300 forms a plurality of second slits 22 between the plurality of second bars 21. In one embodiment, the second slit 22 may be in the form of its inner peripheral surface being sealed as a whole. In another embodiment, the second slit 22 may be in the form of a portion of its inner peripheral surface, particularly the lower inner peripheral surface of the second slit 22. Further, a gap may be formed between the inner circumferential surface of the second slit 22 and the inner circumferential surface of the first rod 14. The juice can be moved to the lower portion between the first module 10 and the second module 20 through the gap juice. The lower side of the second slit 22 may form a juice hole 28. The juice collected in the lower portion between the first module 10 and the second module 20 can pass through the juice hole 28 into the inside of the detachable screw 300. Further, the lower inner peripheral surface of the second slit 22 may have an open shape, and the open inner peripheral surface functions as the juice hole 28.

A through hole 30 through which the screw shaft 11 is inserted may be formed on the top surface 27 of the second module 20. Through hole 30 may be a polygonal hole to fix the combined position of the first module 10 and the second module 20 and prevent relative rotation of the first module 10 and the second module 20. The through holes 30 are illustrated as being quadrangular in FIGS. 2a to 4b, but the shape of the through holes 30 is not limited thereto. In the present specification, the first module 10 and the second module 20 can be fixed at four different positions by a quadrangular shaft, that is, a screw shaft 11 and a quadrangular hole, that is, a through hole 30.

The lower side of the second module 20 may form a seating groove 25 to enable the detachable screw 300 to be placed in the juice jug 200. A projection (not shown) corresponding to the seating groove 25 may be formed to protrude upward from the bottom surface of the juice jug 200. The seating groove 25 is coupled to the mounting projection so as to prevent the separated dross from entering the inside of the screw 300 during the juicing process.

As described above, between the inner circumferential surface of the second slit 22 and the inner circumferential surface of the first rod 14 (that is, the inner circumferential surface of the first module 10 and the outer circumferential surface of the second module 20) Between) can form a gap. The gap may become wider toward the lower side of the detachable screw 300. The gap can ensure that the juice enters the space between the first module 10 and the second module 20 through the slit.

In addition, a magnet accommodating portion 26 may be formed on the top surface 27 of the second module 20. A magnet is disposed in the magnet accommodating portion 26, and a magnet or a magnet having an opposite polarity is disposed on the inner side of the first module 10, so that when the second module 20 is coupled to the first module 10, the second module 20 and the second module are A module 10 is not easily separated, so that the second module 20 can be fixedly coupled to the first module 10.

Further, a first damper 16 may be formed at a lower end of the first rod 14 of the first module 10, and a second ridge 23 may be formed on a lower side of the second rod 21 corresponding thereto. The second ferrule 23 of the second module 20 is engaged with the first ferrule 16 of the first module 10 to withstand the pressure transmitted to the screw 300 and to prevent dross from entering the inside of the screw 300.

Next, a juice extractor to which the detachable screw 300 according to the embodiment of the present invention can be applied will be described.

As shown in Figures 1a and 1b, the juicer can include a feed hopper 100, a juice extraction tub 200, and a detachable screw 300. The inside of the juice jug 200 is provided with a detachable screw 300, and the feeding hopper 100 is detachable It is incorporated into the juice jug 200.

Juice objects (eg, vegetables, cereals, fruits, etc.) enter the juice jug 200 through the feed hopper 100.

The juice jug 200 may be formed in a cylindrical shape in which the upper portion is open, and a detachable screw 300 is placed inside.

The lower portion of the juice jug 200 is formed with a juice outlet 220 for discharging juice and a tap opening 230 for discharging the dross. The juice extract is separated into the dross and the juice by the juice jug 200 and the detachable screw 300, and the dross is left radially outward of the detachable screw 300, and the juice is moved to the radially inner side of the detachable screw 300. Thereafter, the dross is discharged through the tap hole 230, and the juice is discharged through the juice outlet 220 through another path different from the dross discharge path.

A barrel hole 240 is formed in the center of the lower portion of the juice jug 200. The drive shaft is inserted into the barrel hole 240 to transmit power to the detachable screw 300. The inner circumferential surface of the barrel hole 240 may have a shape corresponding to the shape of the drive shaft so that the drive shaft can be inserted.

The inner peripheral surface of the juice jug 200 may form first ribs 250 and second ribs 260 spaced apart in the circumferential direction. The first rib 250 and the second rib 260 may be formed along the length direction or at an acute angle to the longitudinal direction. As the detachable screw 300 rotates, the interaction material that passes through the screw spirals 13, 29 and the first ribs 250 and the second ribs 260 is pressed or pulverized. The second rib 260 can also function to direct the juiced object to the lower portion of the juice extraction tub 200. Further, in addition to the function of pressing and pulverizing the material, the second rib 260 can also function to adjust the position of the detachable screw 300 and adjust the juice extraction space.

The detachable screw 300 receives a rotational force from the drive shaft to perform a rotational motion, and presses or pulverizes the juiced object.

The detachable screw 300 can include a first module 10 and a second module 20. The first module 10 and the second module 20 are detachably coupled.

A screw shaft 11 is disposed at the center of the interior of the first module 10. The screw shaft 11 is further protruded from the top surface of the detachable screw 300 so as to be inserted into the accommodating hole formed in the bottom surface of the feed hopper 100.

A screw hole 12 that receives a rotational force of the drive shaft is opened at a lower portion of the screw shaft 11.

At least one screw spiral portion 13 that can be in contact with the juice jug 200 is formed on the outer peripheral surface of the first module 10.

A plurality of first bars 14 are formed on the first module 10. The plurality of first bars 14 may be formed over the entire length of the first module 10 or may be formed only on a portion of the first module 10 in the longitudinal direction. A plurality of first slits 15 are formed by the plurality of first bars 14. The plurality of first bars 14 may include a first bar 14 having a relatively narrow width and a first bar 14 having a relatively wide width to fix a combined position with the second module 20.

The first rod 14 may have a shape in which the width is narrower toward the inner side in the radial direction of the first module 10. Therefore, it is possible to avoid the problem that the dross in the juicing process causes the gap to be blocked or hinder the flow of the juice. To achieve such a purpose, the cross-section of the first rod 14 can be substantially semi-circular, elliptical or trapezoidal.

A first snap 16 can be formed on the underside of the first rod 14. The second ferrule 23 of the second module 20 is engaged with the first ferrule 16 of the first module 10 to withstand the pressure transmitted to the screw 300 and to prevent dross from entering the inside of the screw 300.

The second module 20 can be configured to be inserted into the first module 10. The second module 20 may have a substantially cylindrical shape with the upper side/lower side open.

The second module 20 includes a plurality of second bars 21 protruding outward in the radial direction, and a plurality of second slits 22 are formed by the plurality of second bars 21. The second rod 21 may be inserted into the first slit 15 between the first rods 14 and form a predetermined gap between the first slit 15 and the second rod 21. The juice enters the radially inner side of the detachable screw 300 through the slit, and the dross remains separated between the detachable screw 300 and the juice rinsing barrel 200. The dross remaining between the detachable screw 300 and the juice jug 200 passes through the detachable screw The space between the 300 and the juice jug 200 moves to the lower portion.

A screw spiral protrusion 29 which is in contact with the juice jug 200 can be formed on the outer peripheral surface of the second rod 21. The bonding position of the first module 10 and the second module 20 can be kept constant so that the screw spiral protrusions 13 formed in the first module 10 and the screw spiral protrusions 29 formed in the second module 20 coincide. That is, it is assumed that the reference point of the first module 10 and the reference point of the second module 20 form an angle of 0° in the circumferential direction at a position where the first module 10 and the second module 20 are completely coupled. When the reference point of the first module 10 and the reference point of the second module 20 have a set angle (for example, 90°, 180°, 270°) in the circumferential direction, the first module 10 and the second Module 20 can be fully integrated. At this time, the screw spiral protrusion 13 formed in the first module 10 and the screw spiral protrusion 29 formed in the second module 20 are identical (that is, a continuous screw spiral portion is formed). In order to keep the bonding position of the first module 10 and the second module 20 constant, the space between the plurality of second bars 21 and the relatively wide space can be repeated every predetermined angle in the circumferential direction. form. A first strip 14 having a relatively wide width may be inserted into a space between the plurality of second bars 21 in a relatively wide space. Therefore, when the first module 10 and the second module 20 are combined, the screw spiral protrusion 13 formed in the first module 10 and the screw spiral protrusion 29 formed in the second module 20 are aligned, so that a continuous screw can be formed. Spiral part.

Unlike this, the screw spiral protrusion 29 may not be formed on the outer peripheral surface of the second rod 21. At this time, by making the width of the second rod 21 narrow, it is possible to achieve the same or similar juice extraction efficiency as the case where the screw spiral protrusion 29 is formed on the outer peripheral surface of the second rod 21.

The upper side of the second rod 21 may form an annular flange 24. The flange 24 serves as a support to fix the spacing between the plurality of second bars 21.

The lower side of the second module 20 may form a seating groove 25 to enable the detachable screw 300 to be placed in the juice jug 200. A gasket can be provided in the mounting groove 25. Therefore, it is possible to prevent dross from entering the inside of the detachable screw 300 during the juicing process.

Between the inner circumferential surface of the first module 10 and the outer circumferential surface of the second module 20 A gap is formed. The gap may be wider toward the lower side of the detachable screw 300. By forming the gap, it is ensured that the juice penetrates into the gap between the first module 10 and the second module 20 through the slit.

As shown in FIGS. 2a and 2b, the detachable screw 300 according to the second embodiment of the present invention may include the first module 10 and the second module 20. The detachable screw 300 can be configured by a combination of the first module 10 and the second module 20.

A screw shaft 11 is disposed at the center of the interior of the first module 10. The screw shaft 11 protrudes from the top surface of the detachable screw 300 toward the upper side.

A screw hole 12 that receives a rotational force of the drive shaft is formed at the center of the inner portion of the first module 10.

A plurality of screw spiral protrusions 13 are formed on a portion of the outer peripheral surface of the first module 10 that contacts the juice extracting tub 200.

A plurality of first bars 14 are formed on the first module 10. A plurality of first slits 15 are formed by the plurality of first bars 14.

The first rod 14 may have a shape in which the width is narrower toward the inner side in the radial direction of the first module 10. Therefore, it is possible to avoid the problem that the dross in the juicing process causes the gap to be blocked or hinder the flow of the juice. To achieve such a purpose, the cross-section of the first rod 14 can be substantially semi-circular, elliptical or trapezoidal.

A first snap 16 can be formed on the underside of the first rod 14. The second ferrule 23 of the second module 20 is engaged with the first ferrule 16 of the first module 10 to withstand the pressure transmitted to the screw 300 and to prevent dross from entering the inside of the screw 300.

The second module 20 can be configured to be inserted into the first module 10. The second module 20 may include a plurality of second bars 21 formed on an outer circumferential surface thereof, and a plurality of second slits 22 formed by the plurality of second bars 21.

The second rod 21 can be inserted into the first slit 15 between the first rods 14 and form a predetermined slit. The juice can pass through the slit into the inside of the detachable screw 300, and the dross is separated between the detachable screw 300 and the juice jug 200 and discharged to the lower portion.

A plurality of screw spiral projections 29 may be formed on a portion of the outer peripheral surface of the second rod 21 that contacts the juice extracting tub 200. The bonding position of the first module 10 and the second module 20 can be fixed such that the screw spiral protrusion 13 formed in the first module 10 and the screw spiral protrusion 29 formed in the second module 20 coincide.
