Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a juicer for grating vegetables, fruits, etc. and squeezing juice from the pulp.

(Prior Art) Recently, juicers that squeeze juice from ground pulp have been equipped with 1. The output shaft of the motor or a rotating shaft that rotates in conjunction with this (hereinafter simply referred to as the rotating shaft, etc.) protrudes, and a mortar-shaped centrifugal separation basket with a mortar at the bottom is rotatably attached to the tip of the rotating shaft, etc. Research has been conducted on a device in which a substantially cylindrical receiving tray is disposed around the centrifugal separation basket to collect the juice filtered by the rotating centrifugal separation basket. The bottom wall of this saucer part has a discharge port for dripping juice into the juice cup below the bottom wall, and the upper opening of the saucer part has a stepped part for fitting. A cylindrical waste case for catching the waste scattered from the centrifugal cage is removably fitted into the stepped portion.

(Problem to be Solved by the Invention) However, in the case of such a juicer, the waste case and the saucer part are fitted together simply by mounting the waste case on the stepped part provided at the upper opening of the saucer part, so centrifugal separation When the basket is rotated at high speed, the juice filtered by the centrifugal basket adheres to the space between the fitting part of the saucer part and the cassette case. There is a problem that it permeates and leaks from the upper opening of the saucer part. In addition, in order to solve the problem of bending, if the stepped part of the upper opening of the saucer part is formed deeper in the direction of the bottom wall of the saucer part, the saucer part becomes larger, which is disadvantageous in terms of miniaturization of the juicer. There's a problem.

(Object of the invention) The present invention has been made focusing on the above problems,
The objective is to provide a high-quality, compact juicer in which juice does not leak from between a saucer part and a waste case.

(Means for Solving the Problems) In order to achieve the above object, the juicer according to the present invention is provided with a rotatable mortar-shaped centrifugal separation cage for juice filtration, which is provided with a dispensing metal part at the bottom. A saucer portion is provided around the centrifuge cage, and a saucer portion is provided with a peripheral wall portion that receives the juice scattered from the rotating centrifuge basket, and an upper opening of the peripheral wall portion of the saucer portion is provided with the A bottomed cylindrical waste case is made up of a bottom wall part facing the upper end opening of the separation cage, and a cylindrical peripheral wall part standing upright on the periphery of the bottom wall part to receive the waste scattered from the upper end opening. In the juicer that is used.

a first vertical wall portion that fits into the outer peripheral surface of the cylindrical peripheral wall portion of the cass case, and a first vertical wall portion that fits into the upper opening of the peripheral wall portion of the saucer portion;
A first step extending from the lower part of the vertical wall to the center of the saucer, a second vertical wall extending downward from the inner corner of the first step, and further extending from the second wall to the center of the saucer. A second step part is formed on the lower surface of the bottom wall of the cassette case, which fits into the second vertical wall part and whose lower end abuts the second step part, so that the lower surface of the bottom wall and the first step part are connected to each other. The first part is for preventing liquid from entering between the parts.
A supporting rib forming a space is erected, and a small step portion forming a second space extending along the corner of the second vertical wall portion and the second step portion is provided at the lower end of the supporting rib. It is characterized by being formed.

(Function) According to this configuration, the centrifugal basket is rotated to unload the fruit, and the ground pulp is lifted up the mortar-shaped centrifugal basket by centrifugal force. The pulp is centrifuged on its way up, and the filtered juice collects in the tray, while the waste after squeezing the juice scatters from the upper opening of the centrifuge basket and adheres to the inside of the waste case. While the process of unloading fruits and the like using the centrifugal basket continues, the juice filtered by the centrifugal basket is scattered toward the cylindrical peripheral wall of the saucer part due to centrifugal force.

However, when the waste case is placed on the upper opening of the peripheral wall of the saucer, the cylindrical peripheral wall of the waste case fits into the first vertical wall, the supporting ribs fit into the second vertical wall, and the waste case fits into the first vertical wall. A first space that prevents liquid from entering is formed between the lower surface of the bottom wall and the first step, and a small step formed at the tip of the supporting rib connects the second vertical wall and the second step. Since the second space is formed at the corner, the infiltration of juice is prevented, and the leakage of juice from the fitting part between the saucer part and the cass case is prevented. Furthermore, since the first space and the second space are extremely small compared to the size of the waste case, the waste case and the receiving tray portion can be formed compactly.
