Description

[Detailed Description of the Invention] The present invention relates to a juicer used for extracting juice from vegetables, fruits, etc., and it reduces the vibration that occurs when extracting juice by centrifugal force generated by rotation, making it easier to use. It provides good jujusa.

Conventionally, a spinner with a cutter fixed to the bottom is rotated at high speed and the finely cut material is retained in the spinner to extract the juice. However, a ring-shaped balance weight is provided on the outer periphery of the top of the spinner to improve the extraction process. It is considered to prevent vibrations caused by unbalance that occurs in In such a method, vibration is reduced by increasing the moment of inertia of the balance weight, so it is necessary to increase the weight of the balance weight.

As a result, the weight of the spinner as a whole increases, making it difficult to handle during use, and the need to balance the spinner itself increases manufacturing costs.

The present invention solves the above-mentioned drawbacks and provides a pumper with less vibration and easy handling.One embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a spinner made of resin and having a cylindrical shape with a bottom. It has a non-porous side wall, and a recess 2 for containing a liquid 18 is integrally provided on the outer periphery of the uppermost part of the spinner. In order to control the movement of the liquid 18 inside, a plurality of plate-shaped partitions 4 having a ribbon-shaped communication portion 3 are provided. Then, a resin cover 5 is placed on top, and liquid is sealed by a method such as thermal welding. The recess 2 and the cover 5 constitute an annular body, which together with the internal liquid and the partition 4 constitutes a balancer. The communication portion 3 of the partition body 4 is provided only at a position closer to the inner wall surface than the center position of the annular body. A cutter 7 having a cutter blade 6 in the shape of a metal cutter is fixed to the bottom. Reference numeral 8 denotes a filter, which is detachable from the spinner 1 and has a flange 9 at the top.
The cylindrical wall has a large number of communicating portions 10 arranged vertically in a straight line. Further, a connector 11 is provided at the bottom of the spinner 1, and is connected to a motor connector 12 to transmit rotation of a motor 13.

14A is the main body of the regulator, and the motor 1
3 is attached, a youth container 14B is placed on top of it, and an input port 15 is placed above it.
A lid 16 is placed thereon. Reference numeral 17 denotes a push rod for pushing the material from the input port 15 into the cutter surface.

Next, the operating state during juice extraction will be explained. First, fit the filter 8 into the spinner 1, and then put the lid 16 on.
will fall into place. Next, by starting the motor 13, the spinner 1 rotates and reaches the resonance point (the primary resonance point at several hundred rpm, the secondary resonance point at approximately
2000rpm) quickly to reach steady rotation.
Reaches 4000rpm. At this time, in order for the spinner 1 to be in a balanced state, the liquid in the recess 2
8 are uniformly distributed, and as shown in FIG. 4, the spinner 8 forms a substantially circular ring along the outer wall 19 of the recess 2 due to centrifugal force, and continues to rotate at substantially the same speed as the spinner 1.
At this time, the liquid amount and the position of the communication section 3 of the partition body 4 are set so that the vertical liquid level of the liquid 18 is located near the communication section 3.

In this state, when material is introduced from the input port 15, the material is cut into small pieces by the cutter 7 and adheres to the inner wall of the filter. This adhered material is compressed by centrifugal force to separate the solid and liquid, and only the liquid is extracted from the communication portion 10, ascends the inner wall of the spinner 1, and is discharged to the outside. By sequentially repeating this operation, a large amount of liquid is extracted, while solids accumulate in the filter 8, and the accumulated solids create an imbalance, causing the entire pump to vibrate. The state of this imbalance changes each time the material is introduced and cut. At this time, in order to automatically balance the spinner with a balancer integrated into the upper part of the spinner and continue rotating smoothly without generating vibrations,
In response to a change in the unbalanced state, it is necessary for the liquid in the recess 2 to move and at the same time gather at a portion opposite to the eccentric load. To do this, at the same time that an unbalanced load is generated by cutting the material, a part of the liquid 18 that has been in an annular shape quickly moves through the communication part 3 of the partition 4 and moves to a position opposite to the unbalanced load. It needs to be in a stable state. In order to control the moving speed and stable state of the liquid 18, it is necessary to appropriate the size of the communication portion of the partition 4. In the case of a slit as in the example, experimental results have demonstrated that the slit width may be set to 0.5 to 2 mm.

If the slit width is narrower than 0.5 mm, the movement of the liquid 18 is delayed when passing the resonance point and when an uneven load occurs, resulting in abnormal vibrations and the vibrations continuing for a long time.

On the other hand, if the slit width is wider than 2 mm, the liquid 18 moves faster, but on the other hand, it is not stable in the position facing the unbalanced load, and abnormal vibrations continue due to the whirling movement due to the inertial movement of the liquid 18. ,
The rotation speed of the spinner will not increase to the steady rotation speed.

In addition, if an imbalance occurs because the communicating portion 3 of the partition body 4 is provided only in the vicinity of the inner wall surface of the liquid 18 which becomes approximately annular in an unbalanced state, a part of the portion near the communicating portion 3 Only the liquid 18 quickly moves through the communication part 3 by an amount corresponding to the amount of unbalance, and most of the liquid 18 is prevented from moving by the partition 4, so some of the liquid 18 that has moved is unbalanced. It gathers smoothly on the opposite side of the load and can quickly achieve a balanced state.

Furthermore, even if no unbalance occurs, the rotational speed of the spinner 1 decreases due to the increase in load when cutting the material, and the liquid 18 moves due to inertia. Since it is provided only near the inner wall surface, movement of the liquid 18 is prevented and rotation can continue in a balanced state.

Further, even if the shape of the communicating portion 3 is one in which fine holes 13 are continuously provided as shown in FIGS. 5 and 6, the same effect can be obtained.

As described above, the juicer of the present invention has the following excellent effects.

1. By providing an annular body on the side wall of the spinner, enclosing the liquid and partitioning it with a partition, the movement of the liquid within the annular body is controlled in response to the occurrence of imbalance that occurs during the cutting process of the material, and the liquid is It quickly moves to the opposite side of the unbalanced load and at the same time becomes stable, making it possible to quickly achieve a balanced state.

2 By providing the communication part of the partition only near the inner wall surface of the liquid, which is approximately annular in a balanced state, it quickly responds to unbalance and maintains a balanced state, and when the spinner rotational speed fluctuates, the liquid It is possible to continue stable rotation by preventing the movement of the

3. The partition body can be molded integrally with the spinner or the annular body, so it can be molded at low cost.

4. The spinner is lightweight as a whole and is extremely advantageous in terms of handling.
