Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a juicer that cuts and crushes the material to be cooked with a cutting blade and squeezes the juice in a squeezing part.

[Technical background of the invention and its problems]

In a conventional juicer of this type, the material to be cooked is first cut and crushed by a cutter installed on the top surface of a rotating body that rotates around a vertical rotation axis, and the cut and crushed material is placed on the circumferential surface of the rotating body. A juicer has been developed that extracts and separates juices by squeezing them using a formed spiral squeezing part, which prevents air bubbles from being mixed into the juices and produces low vibration noise.
No. 58-69575 (Japanese Unexamined Patent Publication No. 59-194710)).

In a juicer with such a structure, the lower surface of the rotor contacts the bearing that supports the rotary shaft protruding from the lower surface of the rotor, so the fibrous material of the material fed to the lower part of the rotor is attached to the rotary shaft. The problem is that fibers get wrapped around the bearing, causing fibers to get into the inner circumferential surface of the bearing, which causes the inner circumferential surface of the bearing to wear easily.Also, it takes time to clean and remove the fibers that are wrapped around the rotating shaft and the fibers that have gotten into the bearing. was.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a juicer in which the fibers of the cut and crushed cooking material are less likely to get caught up in the rotating shaft, and which can be easily cleaned.

[Summary of the invention]

The present invention has a rotary body that has a plate-shaped cutter having a cutting blade on its upper surface and a spiral squeezing portion on its circumferential surface and rotates around a vertical rotation axis, and a rotating body that has a small gap between the squeezing portion of this rotary body and A cooking case, which surrounds the cooking chamber to form a cooking chamber, has a juice outlet and waste discharge port opened on the side of the cooking chamber, and has a through hole in the bottom through which the rotating shaft of the rotating body is inserted; a container body having a fitting portion that removably fits and holds the case and is provided with a drive shaft that is coupled to a lower end coupling portion of the rotating shaft of the rotating body; a lid body that covers the upper opening of the chamber and forms a cooking material inlet facing the cutter; a fixed bearing protruding from the lower surface of the rotating body around the rotating shaft; A movable bearing whose outer periphery upper part is rotatably fitted to the bearing is provided on the rotating shaft so as to be rotatable and movable in the axial direction. When the rotating body is fitted into the cooking chamber, the rotating shaft is connected to the drive shaft by the coupling part, and the upper part of the movable bearing is fitted to the fixed bearing, and the rotating shaft is connected to the drive shaft by the coupling part. The outer movable bearing and the fixed bearing make the diameter of the part where the fibers of the material to be cooked are likely to get wrapped large to prevent the fibers from getting wrapped around, and the movable bearing is separated from the fixed bearing during cleaning. This is what I did.

4, the material to be cooked is put in and pressed against the cutter 49 with a push rod 55. The material to be cooked that is pressed against the cutter 49 is cut and crushed by the cutting blade 51, and fed into the outer circumferential direction of the cutter 49 by centrifugal force, from the feeding guide section 25 of the cooking case 23 to the squeezing section 34 of the rotating body 33. It is sent between the inner surface of the cooking case 23 and the inner surface of the cooking case 23. Then, the material to be cooked is sequentially squeezed in the squeezing section 34, and the separated juices are passed through the filter 30 from the juice outlet 29, flowed into the juice outlet chamber 19, and then from the juice outlet 20 of the juice outlet 19. It flows into the youth container 22. Further, the pomace of the material to be cooked is stored in the dregs storage section 16 through the dregs discharge port 28 of the cooking case 23. The scraps that are not discharged from the scrap discharge port 28 enter between the lower surface of the rotary body 33 and the bottom surface of the cooking case 23, but the rotary shaft 38
A movable bearing 40 is disposed on the outer periphery of the movable bearing 40, and since the outer diameter of the movable bearing 40 is larger than the outer periphery of the rotating shaft 38, the fibers do not wrap around the outer periphery of the movable bearing 40. In addition, the liquid that has entered downward from the stepped portion 13 of the movable bearing 40 presses the lip-shaped edge 48 of the packing 47 against the liquid seal stepped portion 12 and is maintained in a liquid-tight state. Since the lip-shaped edge 46 of the packing 45 is in close contact with the outer periphery of the rotary shaft 38, it does not flow into the insertion hole 11, and the intrusion of dirt and liquid into the container body 1 is prevented.

Further, in the movable bearing 40, the protrusion 42 is fitted and supported by the receiving step part 42 and rotatably supported by the rotating shaft 38, so even if the center of the rotating body 33 is slightly eccentric, the rotating shaft 38, the bearing 37 , 40 do not generate heat or wear out due to the rotation of the rotating body 33,
Furthermore, the locking portion 43 of the movable bearing 40 engages with the protrusion 44, so that rotation is restricted.

In addition, after the use processing is completed, remove the lid body 52,
Pull out the support case 4 and then remove the cooking case 23.
At the same time, the rotating body 33 is removed from the cooking case 23 and cleaned. This cooking case 3
Since the movable bearing 40 provided on the rotating shaft 38 of the rotating body 33 extracted from the rotary body 3 moves downward away from the fixed bearing 37, it can be easily cleaned.

In the above embodiment, the supporting case 8 was provided, and the receiving part 13 and the liquid sealing part 12 were formed in the supporting case 8. A liquid seal stepped portion 12 may be formed.

〔Effect of the invention〕

According to the present invention, a fixed bearing is provided that protrudes from the lower surface of the rotating body having a plate-shaped cutter on the upper surface and a spiral squeezed portion formed on the circumferential surface, and the upper part of the outer periphery is rotatable on this fixed bearing. A movable bearing that is fitted to the rotary shaft is provided to be rotatable and movable in the axial direction, and a receiving step for fitting and holding the movable bearing is formed at the bottom of the fitting part of the vessel body. The shaft is surrounded by a movable bearing, and the outer diameter of the movable bearing is larger than the outer diameter of the rotating shaft, so that the fibrous residue of the cooking material from which the juice has been separated is difficult to wrap around the outer periphery of the movable bearing.
Since fibers do not enter the bearing, there is no wear and tear, increasing the life of the bearing.Also, since the movable bearing slides on the rotating shaft and separates from the fixed bearing, there is no space between the movable and fixed bearing. It is also easy to clean the clogged debris.
