Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer for extracting juice from vegetables, fruits, etc., and aims to prevent vibrations.

Conventionally, in so-called waste retention type juicers that have a cylindrical spinner, the waste cut by the cutter accumulates inside the spinner and remains attached to the inner wall with almost no fluidity, resulting in uneven adhesion of waste. There was a drawback that vibrations were generated due to the uneven distribution of this dregs.

As one of the anti-vibration measures, a method has been considered in which a ring-shaped balance weight is provided above the spinner and the unbalance is absorbed by the inertial force of this balance weight. However, even with this anti-vibration measure using balance weights,
There is a drawback that vibration increases when the unbalanced position approaches the balance weight (the unbalance is at a high position).The present invention eliminates this drawback and suppresses the unbalanced position to a position lower than the balance weight position. , to prevent large vibrations from occurring. Hereinafter, one embodiment will be described based on the drawings. In Fig. 1, reference numeral 1 is a cylindrical spinner with a side wall without holes, and a cutter 3 with a grater-like blade 2 is fixed to the bottom of the spinner, and a ring-shaped cutter 3 is attached to the top outer circumference of the spinner 1. A balance weight 4 is fixed.

Reference numeral 5 denotes a filter, which is removably attached to the inner surface of the spinner 1 and is prevented from coming off upward, and has a flange portion protruding inward at the upper end, as shown in FIGS. 2 and 3. 6, and a large number of slits 7 are provided in the cylindrical wall in a straight line in the vertical direction at a constant width W.

Further, the height of the spinner 1 is set so that the flange portion 6 is located below the position of the balance weight 4 when the filter 5 is attached to the spinner 1. 8 is an input port for inputting materials.

Next, the operation will be explained.

First, the filter 5 is fitted into the spinner 1, and then a lid (not shown) is placed on the spinner 1, and the input port 8, which is integrated with the lid, is placed in a predetermined position. Next, while rotating the spinner 1 at a high speed, material is introduced from the input port 8, and the material is cut into small pieces by the cutter 3 and adheres to the inner wall of the filter 5. This adhered material is separated into solid and liquid by the far D force, and the slit 7
Only the liquid is extracted from the spinner 1, ascends the inner wall of the spinner 1, and is discharged to the outside to obtain juice. At this time, the debris adhering to the inner wall of the filter 5 does not go above the flange 6 of the filter 5, and the flange 6 is located below the balance weight 4. Therefore, the unbalance position due to debris will always be below the balance weight position. It can also be proven from the experiment shown in Figure 4 that the lower the unbalanced position is, the smaller the vibration becomes. The graph C in Figure 4 shows how the amplitude changes with the difference in the distance A in the rotation axis direction between the balance weight 4 and the unbalance a (simulated load) under the conditions shown in A and B. , unbalance a
It can be seen that the closer the balance weight is to the balance weight 4, the stronger the vibration becomes. From this result, it is found that it is more advantageous for vibration if the unbalance is located further down than the balance weight 4, and with the configuration of the embodiment of the present invention, it is possible to suppress the unbalance due to debris to a position lower than the balance weight. It is possible to reduce vibration. As described above, the present invention obtains a vibration-proofing effect by considering the relative position between the balance weight and the flange portion of the filter, and the effect is extremely large in combination with the simple structure.
