Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifter having an autobalance mechanism capable of reducing unbalanced vibrations caused by rotation, and is intended to reduce vibrations when stopped.

Conventionally, in a lees retention type juicer, a so-called auto-balance mechanism, which is a method in which a ring-shaped body filled with liquid is removed from a spinner, has been proposed in order to reduce vibrations caused by unbalance of the lees. However, the drawback of this method is that the autobalancer has no effect at rotation speeds below the resonant frequency of the regulator.
On the contrary, there is a point where it encourages vibration. During steady cutting, the Jusa rotates at a rotation speed higher than the resonance frequency, so the liquid moves in the opposite direction to the unbalance caused by the accumulated lees, canceling the unbalance caused by the lees and reducing unbalanced vibrations. Ru. When cutting is completed and the power is turned off, the rotation speed gradually decreases, and when it becomes below the resonant frequency, the liquid moves in the direction of the unbalanced load due to the lees, promoting unbalanced vibration and causing the spinner to vibrate violently. It may come into contact with the lid.

The present invention solves the drawbacks seen in the above-mentioned conventional examples, and will be described in detail below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a regulator main body, on which a motor 2 is elastically supported via a vibration-proof rubber 3. The output of the motor 2 is transmitted through a speed reduction mechanism 4 to a spinner 20 having a cylindrical shape with a bottom. spinner 20
A cutter 5 is fixed to the inner bottom surface, and a cylindrical comb-shaped filter 6 is fitted to the inner periphery. An annular body 7 is fixed to the outer periphery of the spinner, a liquid 8 is sealed inside the annular body, and a partition plate 9 is installed. A communication portion 11 for flowing liquid is bored from the center of the partition plate 9 to the outer wall 10 of the annular body. The communication portion 11 is not provided on the partition plate 9, but is provided between the end of the partition plate 9 and the outer wall 10.
A gap may be formed between the two and this may be used as a communication section. The partition plate 9 is perpendicular to the spinner bottom surface 12 and has an angle opposite to the direction of rotation shown by an arrow 14 with respect to a plane that passes through the joint between the partition plate 9 and the inner surface of the outer wall 10 of the annular body and includes the spinner rotation axis 13. It is fixed.

Reference numeral 15 denotes a use receptacle, into which a container lid 17 having an input port 16 is fitted. Reference numeral 18 is a push rod for inserting materials, and 19 is a receptacle tip, which are placed on the main body 1.

Next, the action of the above-mentioned juicer will be described. Turn on the power to the motor 2, rotate the spinner 20, input materials such as fruit from the input port 16, and press the push rod 1.
8 leads to cutter 5. Fruits are cutter 5
The waste is crushed by a cylindrical comb-shaped filter 6 and centrifuged, and the waste passes through the upper part of the spinner into a waste receiver 15.
flows to The lees stays and accumulates in the cylindrical comb-shaped filter 6. The extracted youth then flows to the youth receiver 19. As the material is repeatedly introduced in this manner, the lees accumulate in the filter 6 and grow. When this lees is accumulated unevenly, an unbalanced load is generated due to the lees and unbalanced vibration occurs. At this time, the rotation speed of the spinner 20 (r,
p, m) are spinner 20, anti-vibration rubber 3, motor 2
Because it is higher than the resonant frequency Hz of the vibration system consisting of
The auto-balancer mechanism works, that is, the liquid 8 inside the annular body moves to a position opposite to the unbalanced load, canceling out the unbalanced load and reducing unbalanced vibrations. The position of the unbalanced load on the lees changes each time the material is introduced. The liquid 8 flows quickly and cancels out the unbalanced load. That is, when an unbalanced load occurs, the material is being crushed, so the spinner 20 is decelerated. Next, when the load of material crushing is removed, the spinner 2
0 is accelerated and the liquid moves relatively in the direction of arrow 21. In this direction, the resistance of the partition plate 9 is small and the liquid moves quickly, canceling out the unbalanced load.

When the extraction of liquid is finished and the power is turned off, the rotation speed of the spinner 20 gradually decreases, and when it becomes below the resonance frequency, the liquid moves in the direction of the unbalanced load and tries to promote unbalanced vibration, but the spinner 20 Since it is in the deceleration state, the direction of movement of the liquid is in the direction of arrow 22. However, in this direction, the resistance of the partition plate 9 is large and the liquid 8 is difficult to move, so when the spinner 20 is stopped, the imbalance is promoted and the spinner 20 is stopped before the phenomenon of vibration growth occurs. The vibration of the spinner 20 when it is stopped is substantially reduced.

As is clear from the above embodiments, the present invention has the following effects.

1. To deal with the unbalance of the lees that occurs when pulverizing the material and extracting the juice, the liquid inside the annular body flows quickly, canceling out the unbalanced load, and allowing comfortable juice extraction with low vibration.

2. When stopped, the structure of the partition plate prevents the movement of liquid, and the spinner stops quietly without promoting unbalanced vibration, and the spinner does not hit the container lid.
