Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a juicer, which cuts and crushes the material to be cooked with a cutter and presses it with a squeezing part of a rotary body to process the juice. This invention relates to a bearing that supports a drive shaft that rotates the body below the cooking case.

[Conventional technology]

The material to be cooked is cut and crushed by a cutter installed on the upper surface of a rotating body that rotates around a vertical axis of rotation, and the cut and crushed material is passed through a spiral squeezing section formed on the circumferential surface of the rotating body. In this type of juicer that performs pressing and juice processing, in order to pivotally support the drive shaft for rotating the rotating body below the cooking case, the bearing for pivotally supporting the drive shaft is formed below the cooking case. Although a structure is adopted in which the bearing is fitted and supported in the fitting recess, it is necessary to prevent the bearing from rotating.As shown in Fig. 3, the bearing is formed below the cooking case. A bearing 1 that is fitted into the fitting recess and pivotally supports the drive shaft is formed into a substantially cylindrical shape having a drive shaft insertion hole 2, and the lower surface of the bearing 1 is fitted into the recess at an axially symmetrical position on the circumferential surface of the bearing 1. A pair of planar substantially arc-shaped protrusions 3, 3 are protruded to abut on the upper surface of the annularly formed step. A structure may be considered in which locking portions 4, 4 are provided in a protruding manner to prevent rotation of the bearing 1 by being engaged with an engaging projection provided on the surface. The purpose of providing the protrusions 3, 3 and the stepped portion is to fit the seal packing 7 into the lower part of the bearing 1.

[Problem that the invention attempts to solve]

In the conventional structure described above, since the pair of protrusions 3, 3 protruding from the circumferential surface of the bearing 1 are separated, the circumferential surface 5 of the bearing 1 between the protrusions 3, 3 and the stepped portion A gap is created between the inner circumferential edge of the upper surface, and through this gap, the pulp residue and juice of the crushed cooking material from the cooking chamber of the cooking case are transferred between the lower part of the bearing 1 and the stepped part of the bearing fitting recess. There is a problem of leakage into the space.
At this time, the leakage to the outside of the support case is prevented by a seal packing 7 that is fitted into the lower part of the bearing 1 and whose lip portion 6 is pressed against the periphery of the through hole of the support case.
However, fine pulp particles may enter between the bearing 1 and the fitted seal packing 7 due to the pressure caused by the accumulation, and this is often not noticed by cleaning. There was a problem that sometimes they were left without being thoroughly cleaned, resulting in unsanitary conditions.

The purpose of the present invention is to form the protrusion of the bearing into an annular shape so that no gap is generated between the circumferential surface of the bearing and the step of the bearing fitting recess, and to prevent the formation of a gap between the lower part of the bearing and the recess. Pulp scraps from the ingredients to be cooked will not leak into the space between them, and therefore pulp scraps will not get caught between the bearing and the seal packing, making cleaning easy and sanitary. It's about getting Juusa.

Therefore, the pulp residue, juice, etc. of the material to be cooked will not leak into the space 57. Therefore, cut pieces of the material do not get stuck between the seal packing 44 and the bearing 23, resulting in good cleaning performance and hygiene.

According to the above configuration, the annular protrusion 42 of the bearing 23 and the annular step 26 of the bearing fitting recess 24
Since liquid tightness is maintained by the contact over the entire circumference, the seal packing 44 is even unnecessary.

Furthermore, even if the juice separated from the cooking material cut by the cutter 48 is scattered due to centrifugal force, the lip portion 51 of the upper seal packing 50
The upper seal packing 50 is pressed against the inner surface of 2.
The sealing effect of the lip portion 51 is enhanced by increasing the internal pressure, and the juice does not leak from the lid 52.

[Effect of idea]

According to the present invention, the protrusion protrudes from the circumferential surface of the bearing to be fitted into the bearing fitting recess facing the cooking chamber and whose lower surface abuts the upper surface of the annular stepped portion of the recess. Since the lower surface of the protrusion is in contact with the upper surface of the stepped portion over the entire circumference, the space between the lower part of the bearing and the lower part of the recess is small. It is liquid-tightly isolated from the cooking chamber where processing is performed, and during reuse processing, the lower surface of the protrusion is pressed against the upper surface of the step by the pressure inside the cooking chamber, making it more reliable to maintain liquid-tightness. Pulp dregs and juice from the ingredients to be cooked do not leak into this space, and therefore, pulp dregs and the like do not enter the underside of the bearing, resulting in good cleaning performance and hygiene. It is something.
