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. The aim is to provide good jujusa.

Conventionally, juices are extracted by retaining the lees in a spinner with a filter inside the inner wall and a cutter fixed to the bottom. It prevented vibration. In such a conventional method, vibrations are reduced by increasing the moment of inertia of the balance weight, so it is necessary to increase the weight of the balance weight.

This has resulted in disadvantages such as the weight of the spinner as a whole increases, the need to balance the spinner itself, which increases manufacturing costs, and the difficulty of handling when using the juicer. In addition, in order to eliminate these drawbacks, it is possible to install a balance ring filled with liquid at the top of the spinner instead of a balance weight like in a centrifugal dehydrator, but in order to perform the function as a juicer, Merely providing a balance ring would cause problems in handling and extraction of juices.

The present invention aims to provide an easy-to-handle lever that eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a cylindrical spinner with a bottom, which has a non-porous side wall, and a recess 2 for containing a liquid 19 is provided on the outer periphery of the side wall. This recess 2 shares the side wall of the spinner 1, and the inside of the spinner 1 is a flat surface 1' without steps or protrusions. The inner wall of the spinner 1 is sloped toward the upper opening so that the juice can be easily discharged. In addition, a slit 3 is provided in the recess 2 to control the movement of the liquid 19 inside.
A plurality of control boards 4 are provided. Then, a ring-shaped cover 5 having a concave cross section is placed over the concave portion 2 and joined by heat welding, and a liquid is sealed inside. That is, the recess 2 and the cover 5 form a sealed space in which a fluid is sealed, thereby configuring a balancer. Although welding burrs occur at the welded portion 1a of the recess 2 and the cover 5, overall, the entire inner side wall of the spinner 1 is flat, forming a flat surface 1'. Further, a ring-shaped groove may be formed to cover welding burrs, but in this case as well, when viewed as a whole, it constitutes a flat surface as described above.

A cutter 7 having a cutter blade 6 in the shape of a metal cutter is fixed to the bottom of the spinner 1. Reference numeral 8 denotes a filter, which is detachably provided inside the spinner 1, and has a flange 9 at the upper part, and a slit 10 is formed in a straight line in the vertical direction in the cylindrical wall, except for a substantially annular part 9a near the flange 9. A large number of them are provided. The welded part 1a of the balancer component of the spinner 1 is provided at a position opposite to the substantially annular part 9a near the flange 9 of the filter 8. Also, a connector 11 is provided at the bottom of the spinner 1, and a motor connector 12 and motor 13
conveys the rotation of Reference numeral 14 denotes a main body of the juicer, in which a motor 13 is housed, a juice container 15 is placed on top of the main body, and a lid 17 having an input port 16 is placed on top of the juice container 15. Reference numeral 18 denotes a push rod for pushing the material from the input port into the cutter 7 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 17 on.
will fall into place. Next, while rotating the spinner 1 at a high speed, material is introduced from the input port 16, and 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 and solid-liquid separates.
Only liquid is extracted from the slit 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 maintain balance using the balancer integrated with the spinner 1 and continue rotating smoothly without generating vibrations, it is necessary to quickly respond to changes in the unbalanced state and to At the same time as the liquid 19 moves,
It needs to be concentrated in the area opposite to the eccentric load. For this reason, it is necessary to increase the outer diameter of the balancer in order to make it more susceptible to the influence of centrifugal force when moving it, and to increase the amount of unbalance resistance, it is necessary to increase the vertical height. A great effect can be obtained by doing this. Therefore, it is conceivable to provide the balancer not only on the upper part of the spinner 1 but also on the entire outside of the spinner 1. In that case, the recess 2 may be opened downward. Further, the welded portion 1a of the balancer component is a substantially annular portion 9a provided on the filter 8.
Since the filter 8 is provided at a position opposite to
After dispersing over a relatively wide area through the weld area 1
Since it is applied to a, the unbalanced load is applied uniformly without being applied locally. Therefore, the welding strength of the welded portion can be kept low. When extraction of juice is finished, remove the lid 17, hold the upper outer wall of the spinner 1 and the flange 9 on the upper part of the filter 8, pull it upwards, remove it from the motor connector 12, and then remove the filter 8 from the spinner 1. The filter 8 can be pulled out by holding the protrusion at the upper or lower end of the balancer part and the flange 9 of the filter 8, and the solid matter inside can be removed and washed with water. In the case of the juicer of the embodiment, a small amount of welding burr may appear at the joint between the recess 2 and the cover 5, but this amount of welding burr does not have any adverse effect on juice extraction. The same applies to the grooves that cover welding burrs.

As is clear from the above examples, the juicer of the present invention has the following excellent effects.

(1) Since it is a balancer using liquid, the weight of the entire spinner is lighter than conventional ones, which is advantageous in terms of handling and cost.

(2) Since the entire inside side wall of the spinner is a flat surface, it is easy to attach and remove the filter, and it is also easy to clean the squeeze scum that has adhered to the inside of the spinner. Furthermore, it is possible to form a slope on the inside of the spinner that widens toward the opening, making it easier to discharge the spinner to the youth.

(3) Since the entire inner side wall of the spinner is a flat surface and there is no protrusion in the area where drawing residue accumulates,
The inner volume of the filter can be made as close as possible to the inner volume of the spinner, and the amount of squeezed residue accumulated can be increased.

(4) Since the welded part of the balancer component of the spinner is provided at a position opposite to the approximately annular part provided on the filter, the weld strength is improved because no local load is applied to the welded part due to the action of the approximately annular part. This makes it possible to reduce the welding area, minimize the protrusion of burrs inside the inner wall of the spinner, and improve reliability.
