Description

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

Conventional structure and problems thereof Conventionally, in this type of juicing machine, as shown in FIG. 1, the cutter 2 driven by the motor 1 was approximately parallel to the horizontal plane. Therefore, the pieces 3 of fruit etc. cut by the cutter 2 fly out in the horizontal direction as they are, and are not crushed sufficiently finely, resulting in a disadvantage that the juice squeezing rate is low.

OBJECTS OF THE INVENTION The present invention takes into account the problems of the prior art and aims to provide a juicer with an improved reduction rate.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a motor built in a main body, a centrifugal separation cage driven by the motor, and a centrifugal separation cage whose cross section is approximately an inverted mountain, which is fixed to the bottom of the centrifugal separation cage. It is made up of a cutter in the shape of a cutter. As a result, the once-pulverized material pieces are further pressed against the cutter by centrifugal force.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 4 denotes the main body of the controller, the bottom plate 5 of which has legs 6, and a motor 7 attached to a support 8 that protrudes inwardly from the bottom plate 5 via a buffer 9. have. A youth receptacle 10 is placed on the main body 4, and the youth receptacle 10 is provided with a youth receptacle 11 inside and a youth outlet 12 at its bottom. Also, inside the juice receiving container 10, there is a substantially cylindrical centrifugal separation basket (hereinafter referred to as a spinner) whose diameter increases upwardly.
13 are deployed. 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 with a blade height of H ₁ is provided on the upper surface of the cutter 14. 15, and a secondary cutting edge 16 with a blade height of H ₂ is formed. (However, H ₁ > H ₂ ) Youth receptor lid 18 attached to the top of main body 4
is provided with a material input tube 17 that projects downward, and this material input tube 17 has the role of guiding the fruits that are pressed against the cutter 14 by the push rod 19.

In the figure, 10 is a cylindrical comb-shaped filter detachably mounted inside the spinner 13, 21 is a vibration isolator for reducing unbalanced vibration of the spinner 13, and 22 is a vibration isolator for reducing the rotational movement of the motor 7. This is a speed reduction device for transmitting power to the spinner 13.

To explain the operation in the above configuration, when a youth material such as fruits is put into the charging tube 17 and pressed against the cutter 14 by the push rod 19, the cutter 14 is rotating at high speed, so the material is mainly It is cut and crushed by the primary cutting blade 15 with a high height.

This crushed material piece 23 has a cutter 14
Centrifugal force: F acts due to the high speed rotation of . At this time, since the cutter 14 is in an inverted mountain shape and has an upward angle, the centrifugal force F is resolved into a component force F ₂ in the direction of the plane of the cutter 14 and a component force F ₁ in the direction perpendicular to the plane of the cutter 14. be done. Therefore, the material piece 23 moves on the surface of the cutter 14 while being pressed downward by the force F ₂ acting on the material piece 23. At this time, the material piece 23 moves on the surface of the cutter 14 mainly due to the low blade height. 16 to further crush the material.

Note that if the blade height of the secondary cutting blade 16 is high, the effect of re-cutting will not be sufficiently produced because the material pieces 23 themselves are fine, and
If the blade height is low, the blade will become clogged when cutting the material for the first time, resulting in poor cutting performance.

The material pieces cut and crushed as described above are
It stays inside the filter 20 installed in the spinner 13, and is separated by centrifugal force into a lees fraction and a youth fraction, of which only the youth fraction passes through the slit portion of the filter 20 and ascends the inner wall surface of the spinner 13. The juice is discharged into the youth receiving container 10 through the upper opening.

Effects of the Invention As is clear from the above embodiments, the juicer of the present invention has a rotatable, substantially cylindrical centrifugal separation cage with a substantially inverted mountain-shaped cross section on the inner bottom, and a blade height on the top surface. Since the cutter with at least two different types of cutting blades is fixed, when the material is pressed against the cutter, the material is mainly cut and crushed by the primary cutting blade with a high blade height. The centrifugal force caused by the high-speed rotation of the cutter acts on the crushed material pieces. At this time, since the cross section of the cutter is approximately an inverted mountain shape, the centrifugal force is combined with the force in the direction of the cutter surface. , the material section is decomposed into a force perpendicular to the cutter surface, and the material section is moved on the cutter surface by the force in the direction of the cutter surface while being pressed against the cutter surface with a strong force by the vertical force. Since the powder is further finely ground by the lower-height secondary cutting blade, it has the practical effect of improving the reduction ratio.
