Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer that stores lees inside a centrifugal nozzle, and is designed to reduce unbalanced vibrations caused by the lees that occur during juice extraction.

As a method to reduce the rotational vibration of conventional juicers that store lees internally, a metal balancer is replaced with a centrifugal separator as shown in Figure 1, with the aim of reducing weight and cost. Hollow annular body 2 filled with liquid
A juicer equipped with this has been proposed. This type of juicer reduces vibrations caused by unbalanced rotation and exhibits good vibration performance at steady high speeds. However, during juice extraction, due to the load caused by the contact resistance between the cutter 3 and the fruits put in, the rotational speed may drop to about several hundred rpm, albeit for a short time.

When the rotation speed of the centrifugal separator falls below the resonance wave number of the vibration system consisting of motor rubber 4, motor 5, and centrifugal separator 1, the liquid distribution acts to promote vibration, and the balancer effect is lost. It was something. At this time, if the dregs 7 stored in the centrifugal separation valve 1 comes into contact with the outer wall 6 of the charging cylinder, which is a fixed part, the impact may cause abnormal vibrations.

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

In FIG. 2, reference numeral 7 indicates a base plate 8 having legs 9.

- The main body of the server, 10 is a motor attached to the main body 7 via a motor rubber 11, and 12 is a juice receiver which is placed in the main body 7 and has a juice receiver 13 inside and a juice outlet 14 at the bottom. It is a container, and a rotatable substantially cylindrical centrifugal separator 16 is installed on the upper part of the container. A hollow annular body 16 having a liquid sealed therein is fixed to the upper outer periphery of the centrifugal separation lever 15 to form an autobalancer.

17 is a cutter attached to the inner bottom of the centrifugal lever 15, and 18 is a cylindrical comb-shaped filter detachably inserted into the centrifugal lever 15. The upper end of the filter 18 has a protrusion 19 that protrudes from the upper edge of the centrifugal separation lever 16 and is inclined inward. Further, a protrusion 24 is provided in the upper part of the filter 18 .

2o is a juice receiver with a container lid 21 [equipped with a charging cylinder,
The push rod 22 has the role of guiding fruits etc. to the cutter 17.

Next, the operation and effects of the juicer with the above configuration will be explained. The fruits guided to the cutter 17 by the push rod 22 are crushed by the cutter 17, centrifuged by centrifugal force applied by the comb 15, and separated into juice and lees 23 by the cylindrical comb-shaped filter 18.

The juice rises up the inner wall surface of the centrifugal pump 15 and is discharged from above, passing through the juice receiver section 13 and the juice outlet 14 and dripping to the outside. Also, the dregs 23 are stored inside the cylindrical comb-shaped filter 18 at this time. As the juice continues to be extracted, the lees 23 accumulate inside the cylindrical comb-shaped filter 18, and the uneven distribution of the lees generated at this time causes unbalanced vibrations. However, vibrations are normally reduced by the automatic vibration adjustment effect of a hollow annular body 16, which is installed on the outer periphery of the upper part of the centrifugal separator 15 and has a liquid sealed inside.

That is, motor rubber 4. Motor 6, centrifugal separation 15
The rotation number of the centrifugal separation mechanism 15 is higher than the resonant frequency of the oscillating vibration mode of the oscillating system formed by the oscillating system, and therefore, the uneven distribution of the liquid inside the hollow annular body 16 has the effect of canceling out the uneven distribution of the lees. Because it does.

If the accumulation of lees continues, the cylindrical comb-shaped filter-1
The lees overflows from the upper end of 8 and is also stored inside the inwardly inclined protrusion 19. Separately, the lees comes into contact with the outer wall of the charging tube 20, and therefore an impact force acts on the centrifugal separation. Also, at this time, lees and feeding tube 2
o Due to the contact resistance with the outer wall and the contact resistance between the fruits and the cutter 17, the rotation speed of the centrifugal separation roller 16 is 6 and the motor rubber 11. Motor 10. The vibration frequency becomes lower than the resonant frequency of the vibration system consisting of the centrifugal separation coil 15, and the automatic vibration adjustment function of the hollow annular body 16 often does not work. However, even at that time, the gyroscopic effect due to the moment of inertia of the lees stored in the loading portion 19 causes the position of the protruding portion 19 to be farther from the motor support portion, so that the motor rubber 11. It functions to effectively regulate the vibration in the oscillation mode of the vibration system consisting of the motor 10 and the centrifugal separator 15,
The name reduces vibration at low speeds, which was a drawback of conventional models.

As described above, the present invention makes the upper end of the filter inside the centrifugal corner having a hollow annular body filled with liquid protrude from the upper edge of the centrifugal corner, and the protruding part is tilted inward, so that the dregs can be collected here. , it is possible to achieve stable and good vibration performance from high speed to low speed during juice extraction.
