Description

[Detailed Description of the Invention] The present invention relates to a juicer used for extracting juice from fruits, etc., and provides an easy-to-use juicer by reducing unbalanced vibrations caused by rotation. .

In order to reduce unbalanced vibrations of the rotating body, it is often seen that the rotating body is equipped with a hollow annular body filled with an appropriate amount of liquid (so-called an auto-balancer mechanism). In addition, the above autobalancer mechanism,
Some devices are also seen equipped with lees retention type juicers that store a cutting shaft inside.

However, when adopting the above autobalancer mechanism for a lees retention type juicer, the following points need to be taken into consideration.

That is, in the case of a lees retention type juicer, the distribution state of the lees changes from time to time due to cutting of the material, and therefore the unbalanced state of the rotating body (spinner) also changes. At this time, in order to achieve the anti-vibration effect of the auto balancer mechanism,
The liquid sealed in the autobalancer mechanism also needs to move quickly in response to changes in the unbalanced state due to lees.

However, if the moving state of the liquid is too good, a phenomenon of running of the enclosed liquid within the hollow annular body is observed, and the biased state of the enclosed liquid is not stabilized at a location opposite to the unbalanced position of the lees.
As a result, unstable vibrations of the rotating body (spinner) occur.

Similarly, if the amount of movement of the enclosed fluid is greater than necessary,
A problem similar to the above phenomenon occurs.

That is, as explained above, the moving speed of the liquid sealed in the autobalancer mechanism of the lees retention type juicer needs to be appropriately fast and at the same time appropriately delayed, and the amount of liquid moved needs to be appropriate as well. I can understand that.

Conventionally, an autobalancer mechanism used in a lees retention type juicer has a hollow annular body 2 provided at the upper end of a spinner 1 constituting a rotating body, as shown in FIG.
An appropriate amount of liquid 3 and a plurality of partition plates 6 provided with slits 4 for circulating this liquid 3 are provided inside.

FIGS. 2(a) and 2(b) are diagrams showing the relationship between the slit portion 4 and the sealed liquid 3 when centrifugal force is applied due to the rotation of the spindle 1. The state of indicates a parallel state.

The state shown in Fig. 2 (a) is when the amount of sealed liquid is small, and at this time, it is difficult for the liquid to move in response to the momentary changes in the unbalanced position due to lees, and therefore the autobalancer The vibration-proofing effect of the mechanism cannot be fully demonstrated.

In addition, Fig. 2(b) shows a case where there are more liquid ruts than (-), and the amount of water that can be moved at this time is (n1X
t) is the amount of water for the area of . That is, this [11Xt
) The liquid moves and is biased to a position opposite to the unbalanced position of the lees, resulting in the anti-vibration effect of the auto balancer mechanism.

The problem here is that if the amount of movable liquid is too large, it will cause unstable vibration of the spinner 1, as described above. In order to prevent this, it is necessary to set one dimension with great precision, but this is actually a very difficult problem when considering variations in the slit shape, variations in the amount of liquid sealed, etc. Ta.

The present invention eliminates the drawbacks seen in the above conventional example,
One embodiment will be described below based on the drawings.

In FIG. 3, reference numeral 6 denotes the main body of the Genesa having legs 8 on the bottom plate 7, 9 a motor attached to the main body e via a buffer 10, 11 placed on the main body 6, and a juice receiver inside. 12 and a juice receptacle having a juice outlet 13 at the bottom, the juice receptacle is a container, and inside the container 11, a rotatable spinner 14 is disposed, which has a substantially cylindrical shape with a bottom that increases in diameter toward the top. has been done.

The spinner 14 is equipped with a cutting blade 16 at the center bottom, and a plurality of partition plates 18 at the upper end thereof, each having an appropriate amount of liquid 16 inside and a slit section 17 for circulating this liquid 16. A hollow annular body 19 is provided.

2o is a cylindrical comb-shaped filter that is detachably inserted into the spinner 14; 21 is a gies receiver that is a charging tube provided on the container lid 22;
The cutting blade 15 is arranged coaxially with the cutting blade 15, and approximately half of the opening forms an opening, which serves to guide the fruit that is pressed against the cutting blade 15 by the pushing rod 23. This push rod 23
The fruit pressed against the cutting blade 16 is finely crushed and adheres to the inner wall of the filter 20, and then the fruit is crushed by the spinner 14.
The solid and liquid are separated by the centrifugal force generated by the rotation of the spinner 14, and only the liquid (juice) passes through the filter 20, ascends the inner wall of the spinner 14, and is discharged to the outside. That is, the cutting shaft 24 remains inside the filter 20.

25 is a speed reducer of an appropriate type for reducing the rotation of the motor 9 and transmitting the speed to the spinner 14, and 26 is a cooling fan for the motor.

FIG. 4(-) shows that the hollow annular body 1
9 shows a state in which centrifugal force is applied to the sealed liquid 16 in 9.

As is clear from the figure, the state of the sealed liquid 16 is distributed vertically on the outer side of the hollow annular body 19.

On the other hand, at least the shape of the slit portion 17 located on the outer side has a slight angle with respect to the vertical plane.

The anti-vibration effect of the auto balancer mechanism at this time will be explained.

By cutting the material, the distribution state of the lees changes moment by moment, and the enclosed liquid 16 moves accordingly, causing the liquid to be biased to a position opposite to the unbalanced position of the lees.

At this time, the amount of liquid that moves is equal to the flow area of the approximately triangular shape shown in (A) in the figure. This is clearly smaller than the flow area [:11 can be kept low.

Furthermore, even if the amount of sealed liquid varies somewhat, in the case of the groove shape based on the present invention, the increase in the flow area is smaller than in the case of the conventional example (Fig. 2 (b)), and the amount of transferred liquid is The increase should not be more than necessary.

FIGS. 4(b) and 4(C) show examples of other slit shapes based on the gist of the present invention.
7 can also achieve the object of the present invention.

The forming of the hollow annular body 19 described in the explanation can be sufficiently realized by the conventional hot plate welding method, etc. As described above, the juicer of the present invention By considering the shape of the slit portion of the partition plate inside the body, the following excellent effects are achieved.

1. The amount of moving liquid does not increase more than necessary, and unstable vibration of the spinner can be reduced.

2. Even if the amount of sealed liquid varies somewhat, the rate of increase in the circulation area is small, and therefore the rate of change in the amount of liquid transferred is also small.
Unstable vibration of the spinner can be reduced.
