Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking machine, and relates to a structure for performing juice processing by cutting and squeezing using a rotating body having a spiral wing body.

Eliminates the drawbacks of conventional centrifugal separation type juicers, such as the generation of cutting noise due to high-speed rotation, the increase in size due to the centrifugal separation cage, the destruction of vitamin C in juice due to contact oxidation with air, and the hassle of cleaning after use. As an improved juicer for the purpose of Means have been developed to obtain juice by cutting the material through the outer diameter of the wing and squeezing the cut material in the valleys. In such a configuration, it is desirable to minimize the gap between the inner wall of the aperture case body and the outer diameter of the helical wing body of the rotating body. This is because the smaller the gap, the finer the cutting and the more effective the drawing effect. However, when molding a synthetic resin or metal rotating body by injection molding or casting, when a thick solid molded product is molded, there are many variations in dimensions due to deformation and sink marks due to extreme uneven thickness. It is difficult to maintain a constant gap between the outer diameter of the wing body and the inner wall of the aperture case body, and it is necessary to provide an extra gap between the two to account for variations in size. For this reason, it has been difficult to make the gap between the rotating body and the aperture case body minute.

The present invention was created in view of the problems caused by molding a rotating body from synthetic resin and integrally molding a spiral wing body on the outer peripheral surface of this rotating body. By making it hollow, there are no parts with extremely uneven thickness, and by making the wall thickness almost uniform, it prevents dimensional variations due to deformation and sink marks during molding, improves dimensional accuracy, and improves the outer diameter of the wing body. The purpose is to make the gap between the inner wall of the aperture case body as small as possible, and to save the material and weight of the rotating body.

Engagement protrusion 4
1 is compressed by pressing down a push button 43 inserted from the outside of the transmission mechanism housing 4, and the engaging protrusion 41 is moved back.

Next, the hollow rotating body 20 is made of metal or synthetic resin, and the base end of this rotating body 20 is
One end of the rotating shaft 44 inserted into the axis of the diaphragm case body 19 is passed through and sealed with an integrally molded end face plate 45, and is projected outward from the base end opening of the aperture case body 19. A grip portion 51 for pulling out the rotating body 20 from the aperture case body 19 is formed. A sealing lid 47 is welded or adhesively fixed to the distal end surface via an annular sealing material 46 such as rubber to seal the inside of the rotating body 20. The annular sealing material 46 is fitted onto the inner wall of the rotating body 20 so as to protrude slightly inward from this surface, and an annular protrusion 48 protruding from the inner surface of the sealing lid 47 is crimped onto the inner surface of the annular sealing material 46. ing. The other end of the rotating shaft 44 is connected to the airtight lid 4.

A scrap discharge rib 50 is provided protrudingly on the outer surface of the rotating body 20, and the rotary body 20 retreats inside the aperture case body 19 which expands toward the rear in a tapered shape by cutting and squeezing operations, and the front end surface of the rotary body 20 is removed. This prevents pomace from entering if a gap is created between the front end back surface of the aperture case body 19 and the front end back surface of the aperture case body 19. Incidentally, since the rear end surface of the rotating shaft 44 is in contact with the front end surface of the coupling ring 10, the rotating body 20 will not move backward indefinitely.

Further, a rotating shaft 44 that penetrates the rotating body 20 and projects from both ends is rotatably mounted on a bearing of the aperture case body 19, and a coupling portion 52 at the base end of the rotating shaft 44 that projects from one of the bearings 38 Output shaft 9
It is removably fitted into a coupling ring 10 fixed to.

A spiral wing body 53 is integrally formed on the outer periphery of the rotating body 20, and the crest of this wing body 53 becomes a cutting edge portion 54 at a position below the input port 21, and the trough between the blade bodies 53 at the tip. constitutes the pressing section 55. The pitch of the wing body 53 is formed gradually smaller from the base toward the tip, and furthermore, the pitch of the wing body 53 is
The difference between the diameter a of the peak portion and the diameter b of the valley portion becomes gradually smaller toward the tip, and the outer diameter of the blade body 53 is such that there is a slight constant gap a between the inner circumference of the aperture case body 19 and the outer diameter of the blade body 53. The diameter becomes smaller toward the tip from the base end of the rotating body 20. Therefore, the height of the rib 26 for locking the filter 25 of the aperture case body 19 is formed so as not to protrude inwardly beyond the gap s, and the thickness of the filter 25 is thinner than the height of the rib 26. It's summery. In addition, the pitch p of the wing body 53 at the cutting edge portion 54 located below the input port 21 was made slightly larger than the inner diameter d of the input port 21, and a workpiece to be cut approximately equal to the inner diameter d of the input port 21 was input. In this case, it is sent forward while being held between the blades 53 and the edge portion 56 of the lower opening edge of the inlet 21 and the blades 5.
It is designed to be cut by the cutting blade portion 54 of No. 3. Furthermore, a large number of small protrusions 57 for non-slip and crushing purposes are formed in the compressing portion 55 and have a lower diameter than the outer diameter of the wing body 53 at this position.

Next, 58 is a waste receiver, which is supported on the support portion 5 of the base 1 adjacent to the juice container 28, and has an opening 59 opened in front of the side surface on the side of the aperture case body 19. A sludge discharge tube 29 protruding from the base 19 is inserted and fitted, and is sandwiched between the support portion 5 and the sludge discharge tube 29, and furthermore, the rear end surface of the sludge receiver 58 is attached to the front end surface of the motor storage section 2 of the base body 1. When the cooking machine main body 18 is used, the residue receiver 58 comes off and the residue receiver 58 is carried.
from falling off from the base body 1.

Next, the operation of the above embodiment will be explained.

When the coupling portion 52 of the rotary shaft 44 protruding from the case lid 39 of the cooking machine main body 18 is fitted into the coupling 10, the fitting cylinder portion 40 protruding rearward from the case lid 39 engages with the fitting cylinder of the clamp case 11. 13, and are engaged with the rotation prevention of the aperture case body 19 by the rotation prevention flat portion and the engagement protrusion 41 and the engagement hole 42 of this flat portion.
At the same time, the base of the aperture case body 19 is supported by the case receiver 16 extending forward from the aperture case body 19, and the protrusion 60 of the aperture case body 19 is fitted into the groove 17 of the case receiver 16.

Next, by driving the electric motor and rotating the output shaft 9 via the speed reduction mechanism, the rotating shaft 44 connected via the coupling 10 and the rotating body 20 integrated therewith are rotated. In this state, the cooking material input port 2
When the material to be cooked is put in from 1 and pushed by the push rod 22, the material is cut by the cutting blade part 54 of the rotating body 20 and the edge part 56 of the lower opening edge of the inlet 21, and the material is cut into a spiral wing body. Rotating body 2 by 53
0 is transferred to the tip side. In this case, the pitch p of the wing body 53 located below the input port 21 is
When the material is smaller than the inner diameter d of the input port 21, if a material having a size substantially equal to the inner diameter d of the input port 21 is input, the material will be placed on the cutting blade part 54 and cannot be transferred by the spiral wing body 53. Therefore, the pitch p of the wing body 53 located below the input port 21 needs to be larger than the inner diameter d of the input port 21. Cutting blade part 54
The cut material is transferred forward by a spiral wing body 53, fed into a pressing section 55 having a wing body 53 continuous to a cutting blade section 54, and squeezed into the squeeze case body 1.
9 and the valley of the rotating body 20, and the extracted liquid is passed through the juice outlet 23 at the bottom.
The liquid is then flowed out through the small hole 24 of the filter 25 and dripped into the juice container 28. At this time, the pressing part 55
In this case, the pitch of the blade body 53 is gradually reduced, and the difference between the peak diameter a and the valley diameter b of the blade body 53 is also gradually decreased, so the volume of the compressed portion 55 gradually decreases toward the tip. As the pulverized material gradually decreases in volume as it moves forward, the speed of progress decreases, and as the squeezing time increases, the squeezing force increases, effectively separating the fibrous material and the liquid containing pulp. Ru. Furthermore, since the gap between the inner surface of the squeeze case body 19 and the spiral wing body 53 is a constant minute gap s, the material is crushed as finely as possible, and at the same time, the many small protrusions 57 formed in the squeeze part 55 are crushed. This prevents the material fed with strong force from slipping in the pressing section 55 and serves to crush the material. Furthermore, the rotating body 20 retreats due to squeezing within the aperture case body 19, which is tapered toward the front, and a gap is created between this end surface and the inner surface of the end of the aperture case body 19, and the pomace remains. In case of intervention, the ribs 50 on the outer surface of the sealing lid 47 remove the residue to the waste outlet 30.

The fiber residue from which the juice has been squeezed out is sent to the tip of the rotating body 20 and discharged from the residue discharge port 30 through the residue discharge pipe 29 into the residue receiver 58. At this time, the adjustment plate 3 facing the waste discharge port 30
1 by gripping this knob 32 and sliding it in the guide groove 33 to adjust the area of the dregs discharge port 30. For example, when using materials with a lot of pulp such as watermelon or tomatoes, the adjustment plate 31 is moved forward to reduce the opening area of the waste discharge port 30, thereby lengthening the pressing time and increasing the pressing force to contain fine pulp. If fruit juice is obtained and the material contains a lot of fiber, the fiber can be quickly removed by retracting the adjusting plate 21 and increasing the opening area of the waste discharge port 30. Further, during cleaning, the adjustment plate 31 is removed from the opening at one end of the guide groove 33 to facilitate cleaning.
Furthermore, since the rotating body 20 is formed hollow, its wall thickness is approximately uniform compared to a solid body, so deformation due to extreme thickness unevenness during molding and variation in dimensions due to sinkage can be prevented. Therefore, the wing body 53
The diameter of the aperture case body 19 and the blade body 53 are
It is easy to achieve dimensional accuracy of the gap s with the outer diameter of the gap s.
In addition to reducing the weight as much as possible, the overall weight has been reduced to facilitate handling and reduce material costs.

Next, when separating the cooking machine main body 18 into the squeeze case body 19 and the rotating body 20, first, the outside of the fitting cylinder 13 is removed in order to disengage the case lid 39 and the fitting cylinder 13 of the clamp case 11. This engagement protrusion 41
The pressing force of the spring pressing the button 43 is released, the engagement protrusion 41 is retreated from the engagement hole 42 of the fitting cylinder part 40 of the case lid 39, and then the fitting cylinder 13 is released. At the same time when the fitting cylinder part 40 is pulled out, the protrusion 60 on the lower part of the aperture case body 19 that has engaged with the groove 17 of the case receiving part 16 of the fitting cylinder 13 also moves into the groove 1.
7 and the cooking machine main body 18 is removed from the base 1. Next, when the case lid 39 screwed onto the opening of the aperture case body 19 is unscrewed, the grip portion 51 at the rear of the rotating body 20 fitted in the aperture case body 19 protrudes from the rear end of the aperture case body 19. The case body 19 is squeezed by gripping the gripping portion 51 and squeezing the rotating body 20.
Pull it out.

According to the present invention, the rotary body rotatably mounted in the squeezing case and cutting and squeezing the material to be cooked is
The rotating body is hollow and made of synthetic resin, and the spiral wing body that constitutes the cutting blade part and the compressing part is integrally molded on the outer peripheral surface of the rotating body. Since the wall thickness is almost uniform, it is possible to prevent dimensional variations due to deformation and sinkage caused by extreme uneven thickness during molding.This allows for precision in the outer diameter of the wing body, and allows for the adjustment of the aperture case body and wing body. By reducing the gap between the material and the outer diameter as much as possible, the cutting edge of the wing body can cut the material finely, and the squeezing part can strengthen the squeezing action to crush the material and increase the squeezing effect of the youth. Furthermore, hollow rotating bodies are lighter and easier to handle than solid ones, require less power, and can reduce material costs.
