Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dregs retention type juicer used in general households.

Conventional structure and its problems Conventionally, this kind of waste retention type juicer is shown in Fig. 1.
As shown in FIG. 2, a cylindrical centrifugal separation tube 1 having a non-porous side wall and a comb-shaped filter are known. The filter 2 has a protrusion 3 on the outside that is in contact with the inner surface of the centrifugal separation tube 1, and the inner surface where the dregs stay is flat, and
Generally, the comb teeth 21L are formed by providing a plurality of slits 4 in the vertical direction through which the juice passes.

Points to keep in mind when designing a juicer are that even when cutting various materials such as fruits and vegetables, it must be possible to minimize the amount of debris mixed in and to obtain a large amount of clear juice. . With residence-type juicers, all of the shaved material is stored in the centrifuge tube, which increases the time needed to squeeze out the juice. Therefore, it is necessary to squeeze out the juice quickly.

However, with the above-mentioned retention type juicer, among the materials to be squeezed, especially soft and slimy materials such as tomatoes or strawberries, the accumulated scum is shocked by the scum and liquid that is released during successive cutting. Move rapidly. Therefore, the dregs are unevenly distributed during centrifugation,
Unbalanced load causes abnormal vibration. In order to prevent the occurrence of abnormal vibrations, it is necessary to increase the width of the slit 4 of the filter 3 (0.6 m or more) so that the dregs are bitten into the slit 4. However, in the case of other materials, such as apples, if the width of the slit 4 of the filter 3 is large, there is a problem that debris comes out from the slit 4, making it impossible to obtain clear juice.

Moreover, the fact that the inner surface of the filter 2 is flat means that the material accumulated on the inner surface of the filter 2 is relatively slippery regardless of the type of material, which causes a further problem in that the juice extraction time becomes longer.

Purpose of the Invention The present invention solves these conventional problems, obtains a clear juice liquid, makes the waste evenly adhered to the inside of the centrifugal tube, reduces vibrations and makes the noise quieter, and makes it easier to squeeze out the juice. It provides a fast juicer.

Structure of the Invention The juicer of the present invention includes a comb-shaped filter having a plurality of slits installed in a cylindrical centrifugal tube having a material cutting filter at the inner bottom, and comb-shaped teeth constituting the filter. A protrusion is provided on the leading edge of the rotation in the longitudinal direction and inwardly, and this structure prevents the movement of debris and reduces vibration, and also reduces the slit width of the filter. By squeezing out clear juice and increasing the density of the residue adhering to the filter on the slit side, the juice squeezing time is shortened and the amount of juice extracted is increased.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 3 to 6, 10 is the main body of the juicer;
A motor 11 is built-in. Reference numeral 12 designates a container placed on the main body 10, from which a motor shaft 13 protrudes from the center. Reference numeral 14 denotes a connecting shaft fitted to the motor shaft 13, on which a centrifugal separation cylinder 16 is detachably attached via a fitting part 16.

The centrifugal separation tube 16 has a cylindrical shape with a non-porous side wall, and has an annular liquid balancer 17 on its upper outer periphery, in which a liquid 8 such as salt water is sealed. Further, a material cutting cutter 19 is fixed to the bottom of the centrifugal separation cylinder 16.

2o is a comb-shaped filter having a plurality of slits 23, and is detachably mounted in the centrifugal separation tube 16. A convex portion 21a'Ir that forms a gap for passing the juice liquid is provided on the outer surface of the comb-like teeth 21 constituting the filter 20 that is in contact with the inner wall of the centrifugal separation tube 16. A protrusion 22 is provided on the inner surface where the rotation leading side line protrudes vertically and inwardly.

It is preferable to provide this protrusion 22 on each comb-like tooth 21, but it may be provided on only a few locations.

24 is a lid that covers the opening of the container 12, and a material input port 25
, into which the push rod 26 is inserted. 27 is a juice outlet, and 28 is a juice receiver.

The operation in the above configuration will be explained. Material input port 2
When the material is inserted from 5 and pushed in with the push rod 26, it is ground by the rotating cutter 19 for cutting the material. Next, this crushed material to be separated is pressed against the filter 20 by centrifugal force. The material to be separated that has reached the filter 20 stops at a protrusion 22 protruding from the inner surface of the filter 20, and the density of the material to be separated increases at that location, and the liquid is easily squeezed out through the slit 23. Separated centrifuge tube 16
reaches the inner wall surface. Since the centrifugal separation tube 16 has no holes on the side wall surface, a force equal to the centrifugal force acts upward due to the positive liquid flow, and the liquid is blown away from the upper opening edge of the centrifugation tube 16 to the outer periphery and is received in the container 12. The juice is taken out from the juice outlet 27 and remains in the juice receiver 28. Therefore, even if the material is a tomato, the protrusion 2
20 action does not move the waste, and the slit 2
The width of the slit 3 can be made smaller, and the density of waste at the slit portion can be increased to allow the squeezing to be performed in a short time.

Effects of the Invention The juicer of the present invention has the following excellent effects because the protrusion is provided on the inner surface where the residue of the filter accumulates.

(1) By reducing the slit width, it is possible to suppress the outflow of squeezing residue and obtain clear juice.

(2) There is no rapid movement of waste during centrifugation, preventing abnormal vibrations, and any material can be made into juice.

(3) The density of waste at the slit portion of the filter increases, and the time required to squeeze out the juice can be shortened.
