Description

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

Conventional structure and its problems Conventionally, this type of waste retention type extractor was
As shown in FIGS. 1 and 2, a cylindrical centrifuge tube 1 having a non-porous side wall and a comb-shaped filter are known. The filter 2 is provided with a protrusion 3 on the outside in contact with the inner surface of the centrifugal separation tube 1, the inner surface where the waste remains is made flat, and a plurality of slits 4 through which the waste liquid passes are provided in the vertical direction to form comb-like teeth 2a. It is common that it is formed.

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. . In addition, in a retention type juicer, all of the scraped material is stored in a centrifugal tube, which increases the time required to squeeze out the juice. Therefore, it is necessary to squeeze out the juice liquid quickly.

However, with the above-mentioned retention type cutter, especially soft and slimy materials such as tomatoes or strawberries are squeezed, and the scraps and liquid that come out as they are cut one after another are impacted and accumulate. The debris moves rapidly. Therefore, the debris is distributed unevenly during centrifugation, resulting in an uneven load and abnormal vibrations. In order to prevent the occurrence of abnormal vibrations, it is necessary to increase the width of the slit 4 of the filter 3 (0.5 m or more) to allow the slits 4 to bite into the slits. However, other materials, such as
In the case of apples, etc., use slit 4 of filter 3.
If the width is large, there is a problem that dregs will come out from here and it will not be possible to obtain clear juice.

Furthermore, the fact that the inner surface of the filter 2 is flat means that
There is also the problem that the material accumulated on the inner surface of the filter 2 is relatively slippery, regardless of the type of material, and this increases the time required to squeeze out the juice.

Purpose of the Invention The present invention solves these conventional problems, obtains a clear juice liquid, makes the waste evenly adhere to the inside of the centrifugal separation cylinder, reduces vibration and makes the noise quieter, and makes it easier to squeeze out the juice. It provides quick delivery.

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 separation cylinder having a material cutting filter at the inner bottom, and comb-shaped teeth constituting the filter. A protrusion is provided on the rotation leading side edge of the filter to protrude vertically and inwardly. With this structure, it is possible to prevent the movement of debris and reduce vibrations, and also to reduce the slit width of the filter, thereby improving the clarity of the filter. By squeezing out the juice liquid and increasing the density of the residue adhering to the filter on the slit side, the time for squeezing out the juice liquid is shortened and the amount of juice liquid extracted is increased.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the accompanying drawings. In FIGS. 3 to 5, reference numeral 10 denotes a main body of the pump, in which a motor 11 is built-in. 1
2 is a container placed on the main body 10, from which a motor shaft 13 protrudes from the center. 14 is motor shaft 1
A centrifugal separation cylinder 16 is removably attached to the connecting shaft through a fitting part 15.

The centrifuge tube 16 has a cylindrical shape with a non-porous side wall,
There is an annular liquid balancer 17 on the upper outer periphery, and a liquid 8 such as salt water is sealed therein. In addition, at the bottom of the centrifugal separation tube 16 there is a cutter 19 for cutting material.
is fixed.

Reference numeral 20 denotes a comb-shaped filter having a plurality of slits 23, which is detachably mounted in the centrifugal separation tube 16. On the outer surface of the comb-like teeth 21 constituting the filter 20 in contact with the inner wall of the centrifugal separation tube 16, a convex portion 21a is provided in the vertical direction to form a gap for passing the youth liquid, and the squeezed scum of the comb-like teeth 21 is retained. On the inner surface thereof, a protrusion 22 is provided on the leading side edge of the rotation so as to protrude vertically and inward. It is preferable to provide this protrusion 22 on each comb-like tooth 21, but it may be provided on only a few locations.

A lid 24 covers the opening of the container 12 and has a material input port 25 into which a push rod 26 is inserted. 27 is a youth outlet, and 28 is a youth receptor.

The operation in the above configuration will be explained. When the material is put into the material input port 25 and pushed in with the push rod 26, it is ground by the rotating material cutting cutter 19. Next, this crushed object 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 at that point A increases, and the liquid is easily squeezed out and separated at the slit 23. and reaches the inner wall surface of the centrifuge tube 16. and centrifuge tube 16
Since there are no holes in the side wall surface, a force equal to the centrifugal force acts upward due to the liquid pressure, and the liquid is blown from the upper opening edge of the centrifuge tube 16 to the outer periphery and is received in the container 12. It is taken out from the youth outlet 27 and remains in the youth receptor 28 . Therefore, even if the material is a tomato, the protrusion 22
Due to this action, the waste does not move, and the width of the slit 23 can be reduced, and furthermore, the density of the waste at the slit portion can be increased, so that squeezing can 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 filter dregs accumulate.

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

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

(3) The density of waste at the slit portion of the filter increases, making it possible to shorten the time it takes to squeeze out the waste.
