Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a centrifugal type juicer for general household use.

Conventional Structure and Problems Conventionally, in this type of shoe, as shown in FIG. 1, the cutter 2 driven by the motor 1 was parallel to the horizontal plane. Therefore, the pieces 3 of the fruit etc. cut by the cutter 2 fly out in the horizontal direction and are not crushed into sufficiently fine pieces, resulting in a disadvantage that the juice extraction rate is low.

OBJECTS OF THE INVENTION An object of the present invention is to provide a juicer that takes into account the problems of the prior art and improves the juice extraction rate.

Structure of the Invention In order to achieve the above object, the present invention includes a motor built in a main body, a centrifugal cage driven by the motor, and a centrifugal cage with a cross section of approximately ♂ 1 which is not fixed to the bottom of the centrifugal cage. and a square-shaped cutter,
Furthermore, this cutter consists of a primary cutting blade, which is used to first crush the input material, and a secondary cutting blade, which uses centrifugal force to crush the crushed material pieces. has been done.

This structure of the cutter allows the once-pulverized material pieces to be finely crushed again, thus improving the juice extraction rate.

DESCRIPTION OF THE EMBODIMENT A -3 Behmib embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, 4 is the main body of the juicer, the bottom plate 5 of which has legs 6, and a motor 7 inside which is attached via a buffer 9 to a support 8 that protrudes inward from the bottom plate 5. have. The main body 4 has a juice container 1o.
The juice receiver is provided with a juice receiver part 11 inside the container 10 and a juice outlet 12 at the bottom. Further, in this juice receiver, a substantially cylindrical centrifugal separation basket (hereinafter referred to as a spinner) 13 whose diameter increases upward is provided inside the container 10. A circular cutter 14 (hereinafter simply referred to as a cutter) having a substantially inverted mountain cross section is fixed to the inner bottom of the spinner 13, and a primary cutting edge 16 with a blade height Hl is provided on the upper surface of the cutter 14. A secondary cutting edge 16 with a blade height of F2 is formed. (However, H, > F2) A juice receptor lid (S) attached to the upper part of the main body 4 is provided with a material input cylinder 17 that projects downward, and this material input cylinder 17 is pressed against the cutter 14 by a push rod 19. It has the role of guiding fruit.

In addition, 10 in the figure is a cylindrical comb-shaped filter detachably installed in the spinner 13, and 21 is the spinner 13.
A vibration isolator 22 is a deceleration device that decelerates the rotational motion of the motor 7 and transmits it to the spinner 13.

To explain the operation in the above configuration, juice materials such as fruits are introduced into the input cylinder 17, and the pushing rod 19 is used to
If the material is pressed against the cutter 14, since the cutter 14 is rotating at high speed, the material is mainly cut into the primary cutting blade 1 with a high blade height.
It is cut and crushed by 5.

A centrifugal force, F, acts on the pulverized material pieces 23 due to the high speed rotation of the cutter 14. At this time, cutter 1
4 has an inverted chevron shape with an upward angle, the centrifugal force F is equal to the component force F2 in the direction of the cutter 14 surface and the cutter 14
It is decomposed into a component force F1 in the direction perpendicular to the plane of . For this reason,
The material piece 23 moves on the surface of the cutter 14 while being pressed downward by the force F2 acting on the material piece 23 for 5 pages. Note that if the height of the secondary cutting blade 16 is high, the re-cutting effect will not be sufficient because the material pieces 23 themselves are fine, and If the blade height of the primary cutting blade 16 is low, the blade will become clogged during the first cutting of the material, resulting in poor cutting performance.

The material pieces cut and crushed as described above stay inside the filter 20 installed in the spinner 13,
It is separated into lees and juice by centrifugal force, of which only the juice passes through the slit part of the filter 20.
The juice receiver rises up the inner wall surface of the spinner 13 and is discharged into the container 1o from the upper opening.

Effects of the Invention As is clear from the above embodiments, the juicer of the present invention is particularly advantageous in that the cutter is shaped like an inverted ridge, and the centrifugal force of the cutter is used to make the material pieces even finer. Therefore, it is possible to improve the juice squeezing rate, which is of great value.
