Description

[Detailed Description of the Invention] The present invention relates to a juicer that cuts a material with a rotating cutter and centrifugally separates a juice liquid with a cylindrical separation basket.

Conventionally, a juicer with a cylindrical separation cage,
As shown in Fig. 1, there is a grater-like cutter 2' at the bottom of a cylindrical centrifugal tube 1' that is rotationally driven by a motor, and cuts fruits etc. that are put in through the input port 3'. is blown onto the side wall of the separation cylinder, and is separated into scum and liquid by a film 5' having a large number of small holes 4' installed in the separation cylinder and small holes 6' drilled in the side wall of the separation cylinder, and the scum is separated. Remains in the cylinder,
The liquid is extracted to the outside from the outlet 7'. However, the material cut by the cutter 2' is pressed against the side wall of the separation cylinder by centrifugal force and remains attached with no fluidity, resulting in uneven adhesion of debris, and this uneven distribution of debris causes vibrations. The disadvantage is that when cutting materials that are difficult to cut, the cutting speed decreases and reaches near the resonance point.
There are drawbacks such as large vibrations and a reduction in the aperture ratio due to a decrease in rotational speed, and there are no particularly effective anti-vibration measures, such as increasing the weight of the Jusa body or lowering the center of gravity. to reduce vibration.

The present invention eliminates the drawbacks of conventional juicers, provides a lightweight juicer with less vibration even when the unbalance position is high, and makes it possible to use it as an additional function for cooking appliances such as food processors. An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 2, reference numeral 1 denotes a cylindrical separating basket, on the bottom of which a cutter 3 with a grater-like blade 2 is fixed together with a spinner stand 4.
Further, the spinner stand 4 is detachably inserted into a rotating shaft 5, a pulley 6 is provided at the other end of the rotating shaft 5, and rotation of a motor 8 is transmitted through a belt 7. Further, on the inner wall of the cylindrical separation cage 1, a cylindrical filter 1 having a web-shaped slit 9 on the side wall is provided.
0 is inserted, and the upper part of this filter 10 is provided with a flange portion 11 inside. Also,
The filter 10 is locked by a plurality of ring-shaped protrusions 12 provided on the cylindrical separation basket 1 and a recess 13 of the filter 10. Further, a ring-shaped balance weight 14 is fixed to the outer periphery of the cylindrical separation cage 1 at a position above the cutter 3 position. Reference numeral 15 denotes a container, which is placed on the main body 16 and is removably locked. Reference numeral 17 denotes a juicer lid, which is removably secured to the opening of the container 15, and has an approximately cylindrical inlet 1 near its center.
8 passes through it, and its lower end faces the cutter 3 at a small distance. Further, a groove 19 along the inner wall of the lid 17 is connected to a juice extraction port 20. Further, 21 is a charging rod that presses the material against the cutter 3.

Next, the operation of the juicer having the above configuration will be explained. When the motor 8 is rotated, the rotation transmitted by the belt 7 is transmitted to the rotating shaft 5 via the pulley 6, and the cylindrical separation cage 1 and the cutter 3 are rotated. Next, when material is put into the input port 18, the material is finely cut by the cutter 3, blown away by centrifugal force, and adheres to the side wall of the filter 10 in the cylindrical separation basket 1, and the liquid content of the material is removed by the centrifugal force. It passes through the slit 9 of the filter 10, ascends the inner wall of the cylindrical separation basket 1, is blown from the upper end to the outer periphery, hits the lid 17, flows through the groove 19, and enters the extraction port 2.
Extracted from 0. Also, for the waste, filter 10
It cannot pass through the slit 9 and remains in the separation cage 1. The debris remaining in the separation cage 1 rarely adheres uniformly within the separation cage, and an unbalanced force is generated in the separation cage during high-speed rotation, causing it to vibrate. However, due to the large inertia of the balance weight 14 installed at the top of the separation cage, the separation cage rotates stably at high speed. Even if this happens, the rotational speed will not drop even if the cutting position and the amount of cutting resistance change.
Therefore, stable high-speed rotation can be continued without causing vibration. The graph shown in Figure 3C shows the balance weight 14 (190g) and unbalance a under the conditions shown in Figure 3A and B.
This graph shows how the amplitude changes depending on the distance A between the (simulated loads) in the rotation axis direction.As can be seen from this graph, the closer the unbalance a position is to the balance weight 14, the closer the unbalance a position is to the balance weight 14. It can be seen that the amplitude becomes larger as the distance increases, and it can be seen that the effect is greater when the balance weight 14 is placed as far upward as possible from the unbalanced position. In addition, when actually cutting the material, it is not known at what position within the separation cage 1 the imbalance will occur, so it is most effective to install the balance weight 14 at the top end of the cylindrical separation cage 1. Advantageous against vibration. In addition, in a rotating body where the unbalanced position is high with respect to the fulcrum position of the rotating shaft, the unbalanced force will be large and the vibration will be large, so making the shaft of the separation cage 1 higher is disadvantageous accordingly.
If the anti-vibration method uses the balance weight 14,
If the distance A to the unbalance and the weight of the balance weight are considered, vibration can be prevented even if the axis of the separation cage is made high.

Although it is convenient to attach the balance weight 14 to the outer periphery of the upper end of the separation cage 1, the purpose can be sufficiently achieved if it is located above the cutter 3. Further, although the juicer in the embodiment is shown as an attachment for a food processor, the same applies to a single juicer.

As described above, according to the present invention, the balance weight provided in the cylindrical separation cage, which is non-porous and has sufficient strength, provides the most stable rotation during high-speed rotation. Even if unbalance occurs sequentially, vibration does not occur and high-speed rotation can be maintained.Also, even if resistance occurs when cutting the material, the rotation of the separating cage will not decrease even if the cutting position and the magnitude of cutting resistance change. Therefore, it does not affect the drawing rate and cutting performance of the Jusa, which are the original basic performance of the Jusa. Also, since vibration can be prevented only with this balance weight, it is possible to avoid increasing the weight of the main body.
There is no need to lower the center of gravity, and the juicer itself can be made lighter.
By simply using the container and shaft as they are, replacing the cooking cutter and separation basket of the food processor with the shaft, and attaching a juicer lid, it is possible to add a vibration-free juicer function, increasing the width of the food processor as a multi-functional cooking device. This makes it possible to create a cooking device with a wide range of Further, by providing the balance weight on the outer periphery of the cylindrical separation cage, effects such as ease of attaching and detaching the separation filter to the inner wall of the separation cage can be obtained.
