The lower support portion 3 may be formed in a plate shape extending from the bottom of the body 1 toward the lower side of the cylinder cover 200. A residue cup (not shown) for containing the residue may be disposed on the lower supporting portion 3.

The speed reducer housing 4 extends laterally from the center of the body 1 toward the cover 200, and a speed reducer can be disposed therein. The decelerator accommodating part 4 may be formed in a shape corresponding to a lower surface of the cylinder cover 200 so as to be able to mount the cylinder cover 200 thereon.

Next, as shown in fig. 1b, the lower driving type juice extractor according to another embodiment of the present invention is substantially the same as the one embodiment of the juice extractor shown in fig. 1a described above, but is different in that a juice extracting barrel 400 is installed at an upper portion of the main body 1 and a driving shaft 6 of a driving motor 5 can transmit power to the screw 300 on the same axis.

The main body 1 may include an upper support 2 and a lower support 3. A drive motor for generating a drive force and a speed reducer (not shown) for transmitting the drive force to the drive shaft 6 are disposed inside the main body 1.

As for the upper support 2, in order to receive the cylinder cover 200 at an upper portion thereof and to connect the driving shaft 6 to the screw 300, the upper support 2 may be formed in a shape corresponding to a portion of a lower surface of the cylinder cover 200. The upper support 2 is configured such that the drive shaft 6 is connected to the shaft of the screw 300 through a hole formed through the center of the cylindrical cover 200.

The lower support 3 extends from the lower portion of the main body 1 in the direction of the juice outlet, and may be formed in a plate shape (it is not shown in fig. 1b that the extending direction of the lower support 3 is precisely directed in the direction of the juice outlet). A juice cup (not shown) capable of containing juice is disposed on the lower supporting portion 3.

The juice extractor of the present invention shown in fig. 1a and 1b is replaced by a juice extracting tube 400 containing a screw, which will be described later. More specifically, the cartridge cover 200 is replaced by an outside module 20 that configures the juice extractor cartridge 400. The juice extracting tube 400 houses the screw 300 therein, and a drive motor (not shown) of the main body 1 transmits power to the screw 300 via a drive shaft (not shown). The driving motor includes a decelerator (not shown) for decreasing the number of revolutions (about 1800rpm) of the driving motor to rotate the screw 300 at a low speed (about 80rpm or less). Thus, the juice can be squeezed without destroying the nutrients. A juicer having such a configuration is generally referred to as a vertical low-speed juicer.

Fig. 2a (and fig. 5a) and 2b (fig. 5b) are exploded perspective views of the juice extractor according to the embodiment of the present invention shown in fig. 1a and 1b, with the main body removed. As shown in fig. 2a and 2b, a juicing object (for example, vegetables, grains, fruits, etc.) may be put into the funnel 100, and the funnel 100 guides the put juicing object to the juicing barrel 400.

As shown in fig. 2a (and fig. 5a) and fig. 2b (fig. 5b), the juice extractor of the embodiment of the present invention may include a funnel 100, a screw 300, and a juice extracting barrel 400. A screw 300 is disposed inside the juice extracting cylinder 400, and the funnel 100 is detachably coupled to the outer block 20 constituting the juice extracting cylinder 400.

The juice outlet 220 and the residue outlet 230 are formed at the lower part of the outer module 20 of the juice extracting barrel 400. In order to facilitate the discharge of juice, a juice discharge port 220 may be provided to protrude in a tube shape from one side of the juice extracting drum 200. The slag discharge port 230 may be formed to discharge slag from the side of the outside module 20. The juice outlet 220 can be opened or closed by a juice outlet opening and closing mechanism (not shown), and the residue outlet 230 can be opened or closed by a residue outlet opening and closing mechanism (not shown).

A barrel hole 260 is formed in the center of the bottom of the outer module 20 of the juice extractor barrel 200. A driving shaft connected to a motor is inserted into the cylindrical hole 260 and connected to the screw 300, thereby enabling power transmission to the screw 300. The inner circumferential surface of the cylinder hole 260 may have a shape corresponding to the shape of the drive shaft so that the drive shaft can be inserted.

The screw 300 is capable of performing a rotational motion after receiving a rotational force from the driving shaft, and the screw 300 is used to squeeze or crush the objects of juicing. For this, a screw shaft 320 is formed at the bottom of the screw 300, and the upper portion of the driving shaft is coupled to the screw shaft 320 so as to be able to transmit power. At least one first spiral protrusion 310 is formed on an outer circumferential surface of the screw 300, and the first spiral protrusion 310 can be in contact with the juice extracting barrel 400. The objects to be juiced are moved to the lower portion by the first spiral protrusion 310, and are squeezed through the fine slits between the screw 300 and the juice extracting barrel 400.

For this, the interval between the first spiral protrusions 310 adjacent to each other at the upper portion of the screw 300 may be greater than the interval between the first spiral protrusions 310 adjacent to each other at the lower portion of the screw 300. The juice extracting barrel 400 may have a hollow cylindrical or truncated cone shape, and may press or crush juice objects by interaction with the screw 300.

Further, an upper portion of the screw 300 may be inserted into a shaft hole (not shown) formed at a bottom surface of the hopper 100 and supported, so that the screw 300 is fixed and rotated in both upper and lower directions of the shaft. This prevents the screw from vibrating and wearing the device, and reduces noise generated when the screw collides with the inside of the juice extracting tube 400.

Fig. 3a to 4d are views illustrating an embodiment of the juice extracting barrel according to the present invention. The embodiment of the juice extractor of the present invention can be applied to both of the juice extractors shown in fig. 1a and 1 b. Fig. 3a is a perspective view of an inner module according to an embodiment of the present invention, fig. 3b is a cross-sectional view of a portion "a-a" in fig. 3a, and fig. 3c (and fig. 6) and 3d (and fig. 7) are exploded perspective views of a juice extracting tube according to an embodiment of the present invention.

As shown in fig. 3a to 4d, the juice extracting cartridge 400 according to the embodiment of the present invention may include an inner module 10 and an outer module 20. The utility model discloses a juice extraction cartridge 400 is basically by two modules of cylindric inboard module 10 and outside module 20 detachably equipment, forms longer slit when two module combinations to filter out the juice after being squeezed the juice by the screw rod. In addition, the juice extracting tube 400 should be made of a high strength material which is not harmful to the human body, can sufficiently endure the pressure occurring during the juice extracting process, and can constantly maintain the width of the juice discharging slit. In addition, the juice extracting tube 400 is made of high strength material, in an embodiment of the present invention, the inner module 10 and the outer module 20 may be integrally manufactured by Polyetherimide (PEI), and the inner module 10 and the outer module 20 may be manufactured by injection molding.

The inner block 10 is formed in a hollow cylindrical shape with an open upper portion so as to be able to accommodate the screw 300 therein, and has one or more slits 12 formed in a side surface thereof so as to penetrate from the upper portion to the bottom portion. The slit 12 is a through hole formed with two side faces, an upper surface and a lower surface, and the side faces, the upper surface and the lower surface of the slit can be continuously formed without distinguishing boundaries from each other.

The outer block 20 is formed in a cylindrical shape with an open upper portion so as to surround and be detachably coupled to the inner block 10. In the present juice extractor embodiment, the outside module 20 replaces the cartridge cover for receiving extracted juice. The outside module 20 of the present invention is formed with ribs 22 on the inner side surface and is configured to receive the inside module 10. At this time, a juice outlet 220 and a residue outlet 230 are formed at the lower portion of the outer module 20. But no slots as in the inner module 10 are formed. The juice outlet 220 and the dregs outlet 230 may be formed to protrude in a tube shape or the like so that juice and dregs can be easily discharged, respectively. A cylindrical hole 260 is formed at the center of the lower portion of the outside module 20. The drive shaft may be inserted into the bore 260 and transmit power to the screw 300. Further, a structure for mounting the screw 200 and the inner module 10 is formed on the bottom surface of the outer module 20.

The rib 22 formed on the inner side of the outer module 20 is a protrusion including two sides, a convex surface, an upper surface and a lower surface, and the rib 22 is inserted into the slit 12 of the inner module 10 when the outer module 20 is coupled with the inner module 10. The side surfaces, convex surfaces, upper surfaces and lower surfaces of the ribs may be continuously formed without distinguishing boundaries therebetween. The rib 22 is formed in a position and shape corresponding to the slit 12 of the inner module 10 so that a predetermined fixing gap is formed between both side surfaces of the slit 12 of the inner module 10 and both side surfaces of the rib 22 of the outer module 20 in a long manner when the inner module 10 and the outer module 20 are coupled, and juice is filtered through the gap formed on the side of the inner module 10 when juice is extracted. Thereby, dregs may remain inside the inner module 10 of the juice extracting tub 400, and juice can be separated and discharged to the outer module 20 side. That is, the gap between the slit 12 and the rib 22 functions as a mesh of a conventional mesh structure. Thus, it is not necessary to form a circular fine mesh like the conventional net drum, and it is possible to easily clean dregs stuck between the through holes of the slit by forming only the slit in the inner block 10 of the juice extracting drum. Therefore, the two modules can be separated more easily than the prior net cylinder, so that the cleaning is easy, the problem that the mesh holes are blocked in the prior net cylinder is fundamentally solved, the brush which is required to be arranged in the prior vertical stock solution device is not required, and various parts for driving the brush are not required.

The gap interval can be determined according to the need by considering the juicing efficiency of different materials and the specific design conditions of the module, and the gap interval only needs to be the interval capable of filtering dregs in the process of squeezing juice. Such a gap interval can be optimized according to design conditions. In addition, the shape of the slit 12 or the rib 22 is not limited to a rod-shaped hole, an egg-shaped hole, or any other shape as long as it can cross the screw 310 of the screw 300 at a predetermined angle and form a long through hole when the screw 300 is received in the juice extracting tube 400.

Further, in order to naturally detachably provide the inside module 10 on the upper side of the outside module 20, not only the upper portion of the outside module 20 is opened, but also in order that the rib 22 of the outside module 20 is inserted into the slit 12 of the inside module 10 when the inside module 10 is received in the outside module 20, the outer diameter of the inside module 10 is formed to be smaller than the inner diameter of the outside module 20, and the inside module 10 and the outside module 20 may have a substantially cut conical shape which is narrowed downward.

The juice extractor cartridge may have a variety of shapes depending on the type of extractor used. In an embodiment of the present invention, the lengths of the inside module 10 and the outside module 20, which is representatively provided to receive the inside module and simultaneously functions as a drum cover, are similar to each other, and the slit 12 is formed to correspond to the entire length of the inside module 10.

As can be seen from fig. 3a and 3c, in the inner block 10 of the juice extractor of the present invention, which is composed of two blocks, a plurality of

ribs

13, 14 protruding radially inward toward the screw may be formed at predetermined intervals along the inner peripheral surface where the slits 12 are not formed. The

ribs

13, 14 are vertically formed on the inner peripheral surface of the inner module 10 in the up-down length direction.

In the present embodiment, the outside block 20 does not directly interact with the screw 300, and thus the

ribs

13, 14, which crush the juicing objects descending downward by interacting with the screw 300 and assist the squeezing action, are formed only on the inside block 10, not on the inside face of the outside block 20. As can be seen from fig. 4c, an embodiment of the invention is configured to fully receive the screw 300 in the inner module 10, such that the whole body of the screw 300 interacts with the inner module 10. Therefore,

ribs

13, 14 are vertically formed on the whole of the upper and lower portions of the inner module 10 interacting with the screw.

The

ribs

13, 14 function as follows: the material put into the juice extracting barrel 400 can be caught in the narrow portion where the

ribs

13 and 14 are in contact with the screw 300 and descend downward. The

ribs

13, 14 may function to crush and press the material sufficiently together with the screw 300 while the material is lowered downward. Therefore, the

ribs

13 and 14 do not necessarily have to be formed along the longitudinal direction of the juice extracting tube 400, and may be formed in an inclined shape intersecting the thread 310 of the screw 300 and having a certain inclination with respect to the longitudinal direction in order to efficiently transfer and extract the material.

That is, the juice extracting object, which receives the screw 300 inside the inner block 10 and is crushed by the rotating screw 300, is sandwiched between the outer surface of the screw 300 and the inner circumferential surface of the inner block 10. At this time, the material rotated by the rotational force of the screw 300 may collide with the

ribs

13, 14 and descend to the lower side of the inner module 10. Without

such ribs

13, 14, the object to be squeezed juice cannot descend downward and stagnates, or squeezing force or crushing force may be reduced or not generated.

The

beads

13, 14 may be divided into a first bead 13 having a relatively short and low protruding height and a second bead 14 having a relatively long and high protruding height. As can be seen from fig. 3a and 3c, in an embodiment of the invention, the first ribs 13 generally have a length shorter or similar to the length of the slit 12, and the second ribs 14 generally have a length longer than the length of the slit 12. The material is effectively moved from the upper portion to the lower portion of the inner module 10 by the screw and the second ribs 14, and the compression force is gradually increased, thereby pulverizing the material. The juice generated by the pressing by such a compressive force is filtered out through the slits formed when the ribs 22 of the outer module 20 are inserted into the slits 12 of the inner module 10, thereby achieving efficient juicing. At this time, the material crushed by the second ribs 14 while being pushed down along the thread valleys of the screw is more minutely crushed and pressed by the plurality of first ribs 13 formed at the lower side. At this time, the material is forcibly pressed by the applied transfer compression force and juice is discharged, and the juice is ejected and discharged from the slits, thereby increasing the juice extracting efficiency.

A compression force is generated during the material is transferred and compressed by the screw 310 of the screw 300, and the compression force may cause deformation of the inner module 10. In this case, the

ribs

13 and 14 can be used as a member for reinforcing the inside module 10. In an embodiment of the invention, a

rib

13, 14 is formed on one bar 11. In an embodiment of the present invention, the second rib 14 formed to be relatively large may function to reinforce the rigidity of the inside module 10. The inner module 10 has a thin thickness as a whole, and may be weakened in rigidity due to the slit 12. Therefore, the second ribs 14 may be formed on the inside module 10 to reinforce the rigidity of the inside module 10. The function of pushing the juice-extracting target downward toward the lower portion of the juice extracting tube 400 while being crushed by the second ribs 14 is the same as that described above. The second ribs 14 can fix the receiving position of the screw 300 in the juice extracting tube 400 and fix the juice extracting space via the material pushed down by pressure during the juice extracting process.

The second ribs 14 of the inside module 10 may be provided to have the same protruding height from the upper portion to the lower portion, and as can be seen from fig. 3a, the second ribs 14 may also be provided in a shape gradually becoming lower toward the lower portion. The slits 12 are not formed on the surface 10-1 of the outer circumferential surface of the inside module 10 on which the second ribs 14 are formed, and thus the rigidity of the inside module 10 is enhanced.

Further, the second rib 14 may be inclined downward from the upper portion to the lower portion, and a stepped portion 14-1 protruding in a stepped manner toward the screw side is formed at a middle portion thereof. The position, number or protruding height of the stepped portion 14-1 of the second rib 14 may be variously modified depending on the shape of the screw and the design condition of the thread.

In addition, the second ribs 14 may also be gradually lowered toward the lower portion, and the second ribs 14 are not formed at the lower portion of the inner module 10.

In addition, in order to fix the coupling position of the inside module 10 and the outside module 20, a space in which the interval between the plurality of ribs 22 is relatively narrow and a space in which the interval is relatively wide may be formed. A surface of the inside module 20, on which no slit is formed, may be combined in a space in which the interval between the plurality of ribs 22 is relatively wide. The key protrusions 25 may be formed in spaces between the plurality of ribs 22, which are relatively widely spaced.

As can be seen from fig. 3c, in an embodiment of the present invention, a guide surface 20-1 where no rib 22 is formed on the outside module 20 corresponding to an outer surface 10-1 (see fig. 3a) of a surface where the slit 12 is not formed in the inside module 10, thereby also functioning to guide the first module 10 to the outside module 20 and fix the coupling position when the inside module 10 and the outside module 20 are coupled, thereby fixing the slit and preventing the movement thereof. Further, as can be seen from fig. 2a and 3d, a key protrusion 25 may be formed on a portion of an inner circumferential surface of the outside block 20 and a key groove 15 may be formed on an outer circumferential surface of the inside block 10, and a coupling position of the inside block 10 and the outside block 20 may be fixed by inserting the key protrusion 25 into the key groove 15. By inserting the key protrusion 25 into the key groove 15, the coupling position, the relative rotation, and the inclination of the inside module 10 and the outside module 20 can be restricted.

As described above, the first rib 13 is radially protruded toward the screw side, and is vertically formed on the inner circumferential surface of the inner module 10 in the longitudinal direction, and a plurality of the first ribs 13 are protruded and formed on the inner circumferential surface of the inner module 10 in a shape spaced apart from each other. The first ribs 13 serve to finely and uniformly push out and crush the materials such as vegetables, which are crushed by the second ribs 14 by the rotation of the screw and then transferred to the lower part, and perform secondary pressing. Therefore, the first beads 13 have a lower protruding height than the second beads 14 and a shorter length than the second beads 14.

Further, as can be seen from fig. 3a and 3b, in a preferred embodiment of the present invention, the first rib 13 may be formed near the screw rotation direction upstream side edge of the slit 12. The first ribs 13 are formed closer to the upstream side edge of the slit 12 in the screw rotation direction, and function like a speed bump, thereby reducing the phenomenon that dregs and juice are discharged through the slit at the same time due to the decrease of the pressing force of the slit when the material is pressed and transferred. Further, in another preferred embodiment, the first rib 13 may be formed to extend radially inward on an edge formed in the up-down direction in the slit 12. At this time, the height of the first rib 13 may be longer than the width (or width) of the slit 12.

Further, a slope 18 may be formed on an edge of the slit 12 opposite to the edge where the first rib 13 is formed. The inclined portion 18 is explained with reference to fig. 3 b. Fig. 3b is a cross-sectional view of the portion "a-a" in fig. 3 a. As can be seen from fig. 3b, the downstream side edge of the slit 12 of the inner block 10 in the screw rotation direction may be chamfered to form the slope 18. Fig. 3b is a cross-sectional view showing a juice extractor tube pattern viewed from below, so that it is easy for people to understand the pattern in which the ribs 22 of the outer block 20 are inserted into the slits 12 of the inner block 10. The positions of the first rib 13 and the inclined portion 18 are specifically described as follows with reference to fig. 3 b. The first rib 13 is formed on the edge of the slit 12 on the upstream side in the rotation direction of the screw 300 that is provided inside the inner block 10 and rotates, and the inclined portion 18 is formed on the edge of the slit 12 on the downstream side in the rotation direction of the screw 300.

For example, when the screw 300 is rotated in the counterclockwise direction in the inside of the inside module 10, the first rib 13 may be formed extending radially inward on the left side edge of the slit 12, and the inclined portion 18 may be formed on the right side edge of the slit 12.

The ribs 22 of the outer module 20 are inserted into the slit 12, and a predetermined gap is formed between the slit 12 and the ribs 22 to discharge juice to be crushed. At this time, dregs of the object of juicing may be jammed in the gap between the slit 12 and the rib 22. However, the clogging of dregs of the object of juicing in the gap between the slit 12 and the rib 22 can be prevented by the first rib 13 and the inclined part 18 formed on the slit 12.

This is explained in more detail below. When the amount of dregs of the juicing object mashed between the screw 300 and the inside module 10 is small so as not to reach the amount capable of passing over the first rib 13 when the screw 300 rotates inside the inside module 10, the dregs move to the lower side of the inside module 10 along the first rib 13.

When the amount of dross increases to an amount capable of passing over the first rib 13, the dross passes over the first rib 13 and moves to the adjacent first rib 13 by the rotational force of the screw 300. By the height of the first ribs 13, the dross moves back over the gap between the slit 12 and the rib 22 of the outside module 20 to the adjacent first ribs 13. When the dross passes over the first rib 13, since the dross moves to the adjacent first rib 13 by the slope 18 formed on the edge of the slit 12 opposite to the first rib 13, the dross is prevented from jamming in the gap between the slit 12 and the rib 22 of the outside module 20. Also, the dross colliding with the adjacent first rib 13 moves to the lower side of the inner module 10 along the adjacent first rib 13. In addition, the pressing force applied to the gap formed between the slit 12 and the rib 22 is reduced in the process that the object to be juiced passes over the first rib 13, so that the phenomenon that the dregs are jammed in the gap can be reduced to the maximum.

As described above, the juice extracting cartridge 400 composed of two modules is constructed according to the embodiment of the present invention, thereby facilitating cleaning, being capable of improving juice extracting efficiency, and significantly reducing the number of parts due to the use of the cartridge cover as the second module.

Further, in another embodiment, the space between the outer circumferential surface of the inner module 10 and the inner circumferential surface of the outer module 20 may be gradually widened toward the lower side by setting the outer diameter of the inner module 10 and the inner diameter of the outer module 20 accordingly. For this, the inner block 10 may be constructed toward the lower portion of the juice extracting tube such that the outer diameter of the inner block 10 is gradually smaller than the inner diameter of the outer block 20 from the top to the bottom, or one or more steps having an outer diameter that is sharply reduced may be provided at predetermined positions on the outer circumferential surface of the inner block 10. Thus, since the space is widened toward the lower side, the juice discharged through the gap formed between the slit 12 and the rib 22 can be smoothly discharged to the juice outlet 220.

In addition, in another embodiment of the present invention, it is preferable that the circumferential width of the juice discharge slit formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 is set to be wider toward the radial outside. That is, when viewed from the direction in which the juice is ejected, the juice can be smoothly flowed by setting the downstream-side slit interval to be wider than the upstream-side slit interval. For this purpose, the juice extracting tub may have a shape in which a gap between both inner and outer sides of one slit 12 of the inner block 10 is widened toward a radial outer side, and may have a shape in which a width of a convex surface of the rib 22 of the outer block 20 is widened toward a radial inner side. In a preferred embodiment of the invention, as can be seen from fig. 3c and 3d, the width of the bars 11 (the distance between one first slit and an adjacent first slit in the circumferential direction) may be such that it widens towards the radially inner side of the inner module 10. Here, the rods are named for convenience of explanation. Through-hole portions where the slits 12 are formed and plate portions where the slits 12 are not formed are alternately arranged in the circumferential direction in the cylindrical module, wherein the plate portions 11 where the slits 12 are not formed are defined as "rods". At this time, the gap formed between the slit 12 of the inner block 10 and the rib 22 of the outer block 20 of the juicing barrel 400 may be configured to be widened from the radially inner side to the outer side, thereby preventing the phenomenon that the gap is blocked or the flow of juice is blocked due to dregs during the juicing process. For this purpose, the cross-section of the inner rod 11 may be semicircular, elliptical or stepped.

In addition, as shown in fig. 3c and 3d, in an embodiment of the present invention, an annular flange 16 may be formed at the lower end of the inner module 10. The material pushed down along the inner surface of the inner block 10 by the thread valley of the screw is discharged by the flange part, so that the juice can be extracted more reliably and the juice extracting efficiency can be improved. Further, the flange portion 16 may further function to fix the width of the slit 12. Since the underside of the inner block 10 is supported by the flange portion 16, the width of the slit 12 is not changed by the squeezing force during the juicing process. Further, the dregs of the juicing object crushed between the screw 300 and the inner module 10 are moved downward by the first and

second ribs

13 and 14, and at this time, a guide boss 27-1 formed with an inclined protrusion extending from the lower end of the second rib 14 is provided in the upper surface of the flange part, thereby functioning as a guide boss which can smoothly transfer the dregs to the dregs discharging port 230.

Furthermore, as can be seen from fig. 3d, in another embodiment of the present invention, a flange portion 16 may be formed at the lower end of the inner module 10, and a first step 119 may be formed at the connecting end of the flange portion and the lateral lower portion of the inner module 10. Furthermore, as can be seen from fig. 3c, a second step 226 may be formed on the underside of the rib 22 of the outside module 20, corresponding to the first step 119. The first step 119 may be mounted and supported on the second step 226 of such outside module 20. At this time, the flange portion may be inserted and coupled to a lower side of the second step.

Furthermore, as can be seen from fig. 3c, the second step 226 may also slightly protrude radially inward so that the first step 119 is mounted on the second step 226 so as not to contact the lower surface of the inner module 10 with the inner bottom surface of the outer module 20. Thus, a wider juice flowing space can be secured at the lower portion of the outer block 20, and the juice extracting efficiency can be improved.

Furthermore, as can be seen from fig. 3c and 3d, a residue discharge hole 110 may be formed at a lower side of the inner module 10 to allow residue, which is discharged by stagnation of the flange part 16 and completely juiced, to be discharged.

At this time, as can be seen from fig. 3d, a slag discharge regulator 111 may be further provided on the slag discharge hole 110. The slag discharge regulator 111 may be hinged to the inner module 10. The residue discharge adjuster 111 is formed of an elastic spacer, and residues in the juicing process can push the residue discharge adjuster 111 open and then be discharged through the residue discharge port 230. When the inner module 10 is cleaned, since the slag discharging regulator 111 is hinged to the slag discharging hole 110, the slag pushed to the slag discharging hole 110 can push up the gasket of the slag discharging regulator 111 to be easily and automatically removed.

This is explained in more detail with reference to fig. 4 to 10.

Fig. 4b to 4d are partial sectional views of the juice extracting barrel according to an embodiment of the present invention. Fig. 4b is a top view of the juicer cartridge according to an embodiment of the present invention. Fig. 4c is a sectional view taken along the line "a-a" in fig. 4B, and fig. 4d is a sectional view taken along the line "B-B" in fig. 4B. The sectional view in the direction of "A-A" is used to observe the sectional view on the juice outlet 220 side, and the sectional view in the direction of "B-B" is used to observe the sectional view on the slag outlet 230 side. Thus, the juice and slag discharge channels are clearly shown in fig. 4b, 4c and 4 d.

First, referring to fig. 4a, which is a perspective view of the juice extractor tube cut along the direction a-a, a juice discharge groove 297 is formed radially outward of the bottom surface of the outer block 20 around the tube hole 260. Also, a slag discharge groove 298 is formed on an upper surface of the flange portion 16 formed at the lower end of the inner block 10. The juice discharging groove 297 is communicated with the juice discharging port 220, and the residue discharging groove 298 is communicated with the residue discharging hole 110 and the residue discharging port 230.

As can be seen from fig. 4c, juice discharged from the gap formed between the slit 12 of the inner module 10 and the rib 22 of the outer module 20 by interaction with the screw flows along the juice discharge groove 297 and is discharged through the juice discharge port 220 (see the arrow of fig. 4 c).

As can be seen from fig. 4d, the residue after juicing between the inner module 10 and the screw 300 flows along the residue discharge groove 298 and is discharged through the residue discharge opening 230 after passing through the residue discharge hole 110.

At this time, the slag flows along the slag discharge groove 298 through the annular flange portion 16 extending radially inward at the lower end of the inner block 10, and is discharged to the slag discharge port 230 through the slag discharge hole 110. That is, the time for which the object to be juiced stays between the screw 300 and the inner block 10 increases, so that the object to be juiced can be sufficiently juiced, thereby increasing the juicing efficiency.

The flow path of the juice is described below with reference to figure 4 c. The gap between the inner module 10 and the outer module 20 clearly shows the exit path of the juice after pressing. After the material is charged into the upper portion of the hopper 100, the screw 300 rotates and presses the material while transferring the material downward, in which process juice is discharged from the gap between the

juice extracting tubs

10 and 20.

The slag discharge path is explained with reference to fig. 4d, in which the discharge path of the slag pushed to the gap between the inner block 10 and the screw 300 is clearly shown. Although the slag discharge hole 110 formed at the lower side of the inner block 10 is not shown, the slag may be discharged through the discharge hole 110 formed at the lower end flange portion 16 of the inner block, and the slag discharge is automatically adjusted by the spouting pressure by the gasket 239 attached to the lower end side or bottom surface of the inner block.

Further, a cylindrical hole 260 is formed in the center of the inner bottom surface of the outer block 20. The inner circumferential surface of the cylindrical hole 260 may include a gasket (not shown) for waterproofing, or may include a cylinder that protrudes into the inner central space of the screw 300 according to design requirements. As described above, the first step 119 (see fig. 3d) formed at the lower end of the inside module 10 may be mounted and supported on the second step 226 formed at the inner circumferential surface of the outside module 20. Preferably, the first step 119 may be installed and supported on a step 226 (see fig. 3c) formed at the lower end of the rib 22 of the outside module 20.

Further, guide

grooves

291, 292 into which the lower end ring 390 of the screw 300 is inserted and guide bosses (294, etc.) thereof may be provided on an upper surface of the flange portion 16 formed at the lower end of the inner module 10 so as to be able to rotatably mount and support the screw 300. Preferably, the lower end ring 390 of the screw 300 may be provided as a double ring, i.e., a first lower end ring 391 and a second lower end ring 392, and form a first guide groove 291 and a second guide groove 292, which insert and support the first lower end ring 391 and the second lower end ring 392, respectively. In this way, the pressure of the dregs or juice is reduced while the screw 300 is rotatably fixed and supported, thereby preventing the dregs or juice from entering the driving shaft.

Further, a second guide boss 294, which is annular and close to the central axis, may be formed on the hollow inner side surface of the bottom flange portion of the inner module 10 to prevent dregs from being discharged through the juice discharge passage.

Furthermore, as can be seen from fig. 5b, in another embodiment of the present invention, a first screw washer 330 may be combined on the outer circumferential surface of the screw shaft 320. When the screw shaft 320 is inserted into the cylindrical hole 260, the first screw washer 330 closes the outer circumferential surface of the cylindrical hole 260. Thereby, juice can be prevented from entering the inside of the cylinder hole 260 during the juicing process.

Further, a gasket groove 340 may be formed between the first and second lower end rings 291 and 291 on the lower outer circumferential surface of the screw 300, and a second screw gasket 395 may be coupled to the gasket groove 340 (see fig. 5b, 4c, and 4 d). When the shim groove 340 is mounted to the mounting portion 293 formed at the inner lower side of the inner module 10, the second screw shim 395 closes the inner side of the mounting portion 293. Thus, the dregs can be prevented from entering the juice discharge port 220 during the juice-extracting process.

One embodiment of the inboard 10 and outboard 20 modules is described in further detail with reference to fig. 6. Ribs 22 may be formed on the inner circumferential surface of the outside module 20. The slit is not formed on the inner peripheral surface of the outside module 20 according to an embodiment of the present invention. That is, the inner peripheral surface of the outer block 20 is formed of a continuous surface.

In addition, when the inside module 10 and the outside module 20 are combined, the rib 22 of the outside module 20 is inserted into the slit 12 of the inside module 10. By inserting the rib 22 into the slit 12, a predetermined gap can be formed. The size of the gap may or may not be constant. Through the gap, juice is drained, and the sludge gathered to the lower portion of the inside of the inner module 10 may move to the outer module 20 through the sludge discharge hole 110, and finally discharged through the sludge discharge port 230 formed at one side of the lower portion of the outer module 20.

In another embodiment of the present invention, the lower juice discharge slit of the juice extracting barrel from which juice is filtered can be set narrower than the upper juice discharge slit by setting the widths of the slits 12 and the ribs 22 accordingly. In the inner block 10 of the juice extractor 400, the material is transferred to the lower side by the rotation of the screw 300, and the gap between the screw 300 and the inner circumferential surface of the inner block 10 is gradually narrowed toward the lower side, so that the material is gradually compressed, the particles become smaller, and the compression force by the compression of the material is gradually increased toward the lower side. Accordingly, the lower slits of the juice extracting barrel 400 may be set to be narrower than the upper slits. In addition, dregs generated during the juicing process may block the juice drainage through the lower slits depending on the material. Accordingly, the upper slit of the juice extracting tub may be provided to be relatively wider than the lower slit so that juice can overflow through the upper slit.

Thus, it is possible to reduce an excessive pressure applied to the upper portion of the juice extracting tube, to more sufficiently filter particles of a material reduced by a compressive force increased toward the lower portion, and to discharge juice overflowing by dregs at the lower side through the upper side slits, thereby improving the juice extracting efficiency. For this, the width of the through hole of the slit 12 of the inner module 10 may be set to be widened toward the lower side, and the width of the rib 22 of the outer module 20 may also be set to be widened toward the lower side. As can be seen from fig. 5a to 8, in an embodiment of the present invention, the width of the upper side of the slit 12 is smaller than the width of the lower side of the slit 12. Further, the width of the slit 12 may be narrowed toward the upper side. At this time, the juice discharge slit may be set to be wider toward the upper side, for example, by setting the width of the rib 22 of the outside module 20 to be narrower toward the upper side than the width of the slit 12.

Further, it is preferable that a step part 121 is formed in the slit 12 of the inner module 10, and an upper slit width is set to be smaller than a lower slit width with reference to the step part 121, while a step part 24 is formed on the rib 22 of the outer module 20, and a width of the lower rib 22 is set to be larger than an upper width with reference to the step part 24. Differently from this, the width of the slit 12 of the inner module 10 may be set to be constant, and the width of the upper rib 22 of the step portion 24 may be set to be narrower toward the upper side of the step portion 24, thereby widening the size of the gap toward the upper side with reference to the step portion 24.

As can be seen from fig. 6, in another embodiment of the present invention, the width of the upper side rib 22 of the outside module 20 may be set to be smaller than the width of the lower side rib 22. Further, the width of the rib 22 may be set to be narrower toward the upper side. Further, a step portion 24 may be provided on the rib 22, and the width of the upper rib 22 may be set smaller than the width of the lower rib 22 with reference to the step portion 24. Further, the width of the upper rib 22 of the step portion 24 may be narrowed toward the upper side.

In the case where the object to be juiced is a hard material such as carrot, most of the juice can be discharged through the slit formed at the lower side during the squeezing process. However, when the object to be squeezed is a soft material such as tomato, juice can be discharged not only through the slit formed on the lower side during squeezing but also through the wide slit formed on the upper side as the object to be squeezed rises up due to accumulation in the slit on the lower side. Thus, when the size of the gap is not uniform in the longitudinal direction or the vertical direction, the juicing efficiency can be improved for both a hard juicing object such as carrot and a soft juicing object such as tomato. The size of the gap does not change during the juicing process, but can be kept constant. In addition, in the case where the object to be juiced is a hard juicing material such as carrot, the juicing material may be jammed in the gap and accumulated during the juicing process. At this time, as shown in fig. 6, the object to be juiced is caught by the step portion 24, and the object to be juiced can be prevented from being accumulated in the gap.

Referring to fig. 5a to 10, the technical solution related to the slag discharging regulator will be described in more detail.

Fig. 5a and 5b are exploded perspective views of a juicer to which a residue discharge regulator according to an embodiment is applied, fig. 6 and 7 are exploded perspective views of a juicer to which a residue discharge regulator according to an embodiment is applied, and fig. 8 is a partially cut-away perspective view of a juicer to which a residue discharge regulator according to an embodiment is applied.

First, the entire juice extractor to which the juice extracting cartridge is applied is summarized with reference to fig. 5 to 8. However, the description of the main body portion in which the drive motor and the speed reducer are arranged has been described above, and therefore, the description is omitted.

The juice extracting barrel 400 has a hollow cylindrical or truncated cone shape, and can extract or crush juice by interaction with the screw 300. The juice extracting cartridge 400 of an embodiment of the present invention may include an inner module 10 and an outer module 20. The juice extractor 400 may be constructed by a combination of the inside module 10 and the outside module 20, the inside module 10 and the outside module 20 being detachably combined with each other. Wherein, as can be seen in FIG. 6, the inner diameter D2 of the outer module 20 may be sized to be larger than the outer diameter D1 of the inner module 10 (D2> D1). Thereby, the inner module 10 can be smoothly inserted into and coupled to the outer module 20.

The inner block 10 is substantially cylindrical and is open at its upper and lower sides. A plurality of slits 12 are formed on the inner module 10. In addition, a first rib 13 and a second rib 14 may be formed on the inner circumferential surface of the inner module 10. In the juicing module, the material may be squeezed or pulverized by the rotation of the screw 300 and by the interaction of the first spiral protrusions 310 and the

ribs

13, 14. Further, the first rib 13 is preferably formed adjacent to the slit 12.

In addition, ribs 22 are formed on the inner peripheral surface of the outer module 20. Such ribs 22 can be inserted into the slots 12 formed on the inner module 10. Wherein no slit is formed on the inner circumferential surface of the outer module 20. That is, the inner circumferential surface of the outside module 20 is configured by a continuous surface, and surrounds the inside module 10. At this time, the rib 22 may not be formed on the inner circumferential surface of the outer module 20, which corresponds to the surface of the inner module 10 on which the slit 12 is not formed. In this space, a peripheral surface of the inner block 10 where no slit is formed may be provided, or a key protrusion 25 may be formed. In correspondence with such a key protrusion 25, at least one key groove 15 may be formed on the upper-side outer circumferential surface of the inner module 10 around which the key protrusion 25 is inserted.

In an embodiment of the present invention, the rib 22 is inserted into the slit 12 when the inside module 10 and the outside module 20 are combined. That is, by inserting the rib 22 into the slit 12, a predetermined gap can be formed between the slit 12 and the rib 22. The extracted juice can be discharged through the gap. Thereby, dregs may remain inside the inner module 10 of the juice extracting tub 400, and juice may be separated and discharged to the outer module 20 side. In addition, an annular flange portion 16 may be formed at the lower side of the inner block 10.

A juice outlet 220 and a residue outlet 230 are formed at the lower portion of the outer module 20. In order to easily discharge juice, a juice discharge port 220 is formed to protrude in a tubular shape from one side of the juice extracting tub 400. The slag discharge port 230 may be formed to enable the slag to be discharged to the outside of the outside module 20. In addition, a slag discharge regulator 719a may be further coupled to the slag discharge hole 719. That is, dregs generated during the juicing process may be collected at the inner lower portion of the inner module 10, and discharged to the outside through the dregs outlet 230 of the outer module 20 after being pushed out of the dregs discharging hole 719 by pushing the dregs adjuster 19a open.

Referring to fig. 5a to 8, an embodiment related to the slag discharging regulator will be described in more detail. An insertion portion 11a may be formed at a lower side of an outer circumferential surface of the inner block 10, and a drain hole 719 communicating with the inside of the inner block 10 may be formed at the outer circumferential surface of the inner block 10 at the lower portion of the insertion portion 11 a.

An insertion groove 28 may be formed on a lower side of an inner circumferential surface of the outer module 20 to correspond to the insertion portion 11a, and the insertion portion 11a may be inserted into the insertion groove 28 when the inner module 10 and the outer module 20 are coupled.

Thus, when the inner module 10 is inserted into the outer module 20, the insertion portion 11a is inserted into the insertion groove 28 to guide the movement of the inner module 10 and also perform a function of positioning the inner module 10 inside the outer module 20.

In addition, a slag discharge regulator 719a may be further coupled to the slag discharge hole 719. An upper portion of such a slag discharging regulator 719a may be hinged to the insertion portion 11a so that an outer circumferential surface of the inner module 10 rotates upward to selectively open and close the slag discharging hole 719. Wherein the slag discharging regulator 19a may be constructed of a gasket.

That is, dregs generated during the juicing process may be collected at the inner lower portion of the inner module 10, and discharged to the outside through the dregs outlet 230 of the outer module 20 after pushing the dregs regulator 719a open from the dregs discharging hole 719. At this time, the slag discharging regulator 719a is constructed of an elastic member, one side of which can be contacted and resisted with the projection of the cylinder cover, so that the slag can be automatically discharged only in case of exceeding the set pressure.

Further, when the user detaches the inside module 10 from the outside module 20 to wash, the user may rotate up the slag discharging regulator 719a hinged with the insertion portion 11a, thereby easily removing the slag that may be stuck in the slag discharging hole 719.

As can be seen from fig. 5 and 6, a first screw washer 330 may be coupled to an outer circumferential surface of the screw shaft 320 of the present invention.

Such a first screw washer 330 closes the outer peripheral surface of the cylinder bore 260 when the screw shaft 320 is inserted into the cylinder bore 260. Thereby, juice can be prevented from entering the inside of the cylinder hole 260 during the juicing process.

Further, a washer groove 340 having a diameter larger than that of the first screw washer 330 may be formed at a lower portion of the screw 300.

Among them, as can be seen from fig. 8, guide grooves 290 for mounting the gasket grooves 340 may be formed on the lower inner surface of the inner module 10.

Thus, when the screw 300 is inserted into the inside of the inner module 10, the second screw gasket may be coupled between the guide groove 290 and the gasket groove 340 so as to close between the guide groove 290 and the gasket groove 340.

That is, when the gasket groove 340 is fitted in the guide groove 290 formed in the lower inner surface of the inner module 10, the second screw gasket closes the inside of the guide groove 290. Thus, the dregs can be prevented from entering the juice discharge port 220 during the juice-extracting process.

Fig. 9 and 10 are perspective views of an inner module of a juicer cartridge adapted with a residual discharge regulator according to another embodiment. Referring to fig. 9 and 10, another embodiment to which the slag discharging regulator is applied will be described in detail.

Referring to fig. 9, in another embodiment of the inner module 40, the outer shape, structure, shape and characteristics are the same as those of the previous embodiment except for the arrangement positions of the slag discharge hole and the slag discharge regulator, and thus detailed description thereof will be omitted.

In another embodiment of the present invention, an insertion portion 48 may be formed on a lower side of an outer circumferential surface of the inner side module 40, and a slag discharge hole 49 communicating with the inside of the inner side module 40 may be formed at a lower end of the insertion portion 48.

An annular flange 46 connected to the insertion portion 48 may be formed at the lower end of the inner block 40, and a coupling groove 49b coupled to the slag discharge adjuster 49a may be formed at the lower end of the insertion portion 48 corresponding to the slag discharge hole 49.

Wherein, a combining groove 49b may be concavely provided from the lower surface of the flange 46 to the upper side for combining with the slag discharging regulator 49a to smoothly close the slag discharging hole 49.

Thus, one end of the slag discharging regulator 49a facing the radial inner side may be hinged to the coupling groove 49b to rotate to the lower portion of the inner block 40 and selectively open and close the slag discharging hole 49.

That is, when the dregs generated in the juicing process are accumulated in the lower part of the inner side of the inner module 40 by a predetermined amount or more, the dregs push the dregs regulator 49a from the dregs discharge hole 49. At this time, the slag discharging regulator 49a may be constructed of an elastic member, one side of which can be contacted and resisted with the boss of the cylinder cover, thereby automatically discharging the slag only in case of exceeding the set pressure.

In this case, as can be seen from fig. 10, the slag discharging regulator 49a can rotate downward by the slag discharged from the slag discharge hole 49 to open the slag discharge hole 49, thereby discharging the slag to the outside of the outside module 20 through the slag discharge port 230 of the outside module 20.

Further, when the user cleans the inside module 40 of another embodiment of the present invention by detaching it from the outside module 20, the user can rotate the slag discharging regulator 49a hinged to the coupling groove 49b downward and easily remove the slag that may be jammed in the slag discharging hole 49.

As described above, according to the embodiment of the present invention, the juice extracting tube 400 is constructed by the two modules of the inner module 10 and the outer module 20, thereby facilitating the cleaning and improving the juice extracting efficiency.

Furthermore, according to the utility model discloses an embodiment can be transferred the material by screw rod 300 smoothly in squeezing the in-process to improve the rate of squeezing juice through the small crushing and the squeezing of material, and can drop into the material smoothly.

Furthermore, according to the utility model discloses an embodiment, can prevent the problem at juicing barrel 400 at the dregs jam of juicing in-process, and can prevent that the juice after the juice is squeezed from flowing the phenomenon that receives dregs hindrance.

Furthermore, according to the utility model discloses an embodiment, can prevent the deformation of the juice extraction section of thick bamboo 400 of the in-process of squeezing the juice. This prevents the slits 12 from becoming large, and can keep the interval between the slits 12 for draining juice constant.

Furthermore, according to an embodiment of the present invention, the assembling and disassembling of the juice extracting cylinder 400 provided on the juice extractor can be easily performed, and the manufacturing is easy.

As described above, the juice extracting tube according to the embodiment of the present invention is configured to be able to combine two modules in the up-down direction, so that the assembly and disassembly of the two modules are easy, and the cleaning is convenient.

Further, by the first rib and the inclined part formed on the first slit, clogging of dregs in a gap for discharging juice formed between the two modules can be prevented, and thus the juice extracting efficiency can be improved.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above, and various modifications can be made within the scope shown in the claims, the detailed description and the drawings, which obviously belong to the scope of the present invention.
