DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household residue type juicer.

[0002]

2. Description of the Related Art As shown in FIG. 10, a conventional juicer of this type cuts food by integrally providing a cutter 2 with a separation basket 1 which is driven to rotate at a low speed of 4 to 5,000 revolutions per minute. The cut food is scattered and retained on the filter 3 provided in the separation basket 1, and the juice is centrifuged and taken out.

[0003]

However, in the above-mentioned conventional construction, the rotation speed cannot be increased due to the occurrence of unbalanced rotation due to the accumulation of the cake in the separation basket 1 and the restriction on the strength of the separation basket itself. Was. For this reason, there is an advantage that the residue is collected in the filter 3 to sufficiently separate the juice and that the residue treatment after use is easy. On the other hand, since the food is cut at a low speed, the juice is not cut finely. The yield did not increase much.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a juicer in which a food is finely cut to sufficiently separate a juice and to easily treat a cake after use. .

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention separates the rotation of a cutter and a separation basket, makes the rotation speed of the cutter higher than the rotation speed of the separation basket, A vertical stopper is provided to prevent the cutter from falling out of the separation basket.

[0006] This allows the cutter to exceed the limit of the separating basket and to increase the rotation speed, and can cut the food finely to sufficiently separate the juice. Further, although the rotation of the separation basket and the cutter are separated, even if the separation basket is turned upside down, the cutter does not drop unexpectedly.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 comprises a main body having a built-in electric motor, and a residue disposed inside the main body and rotated by the electric motor. A separation basket with a filter for separating juice, and a cutter arranged in the separation basket,
The rotation speed of the cutter is higher than the rotation speed of the separation basket, the separation basket is provided with a substantially circular vertical retainer having an inner shape, and the cutter is provided with a vertical retainer having a substantially circular outer shape. The outer diameter of the retainer is made larger than the inner diameter of the retainer of the separation basket, and the cutter is loosely fitted in the separation basket, and the cutter is configured not to fall out of the separation basket. .

As a result, the rotation speed of the cutter can be higher than the limit of the separating basket, and the food can be finely cut to greatly improve the yield of juice. Further, although the rotation of the separation basket and the cutter are separated, even if the separation basket is turned upside down, the cutter does not drop unexpectedly.

[0009] The invention according to claim 2 is to prevent the separation basket from falling off.

Of the juicer.

[0010] With this configuration, when the cutter is mounted on the separating basket, the cutter does not drop unexpectedly even if the separating basket is turned upside down, and can be easily disassembled and washed during washing. According to a third aspect of the present invention, a high-speed rotating shaft and a low-speed rotating shaft are arranged on a main body, a cutter is fitted to the high-speed rotating shaft, and a separating basket is fitted to the low-speed rotating shaft. The juicer described.

[0011] This makes it possible to completely separate the cutter and the separating basket and individually arrange them on the main body.
It is easier to clean the cutter and the separation basket respectively.

According to a fourth aspect of the present invention, there is provided the juicer according to the first or second aspect, wherein the outer peripheral portion of the back surface of the cutter portion and the inner peripheral portion of the bottom surface of the separation basket are vertically overlapped.

[0013] This makes it difficult for the residue and the like to enter the gap between the cutter and the separation basket, and also to prevent the juice from spilling on the main body even when a small amount of juice or the like is accumulated in the separation basket.

According to a fifth aspect of the present invention, there is provided the juicer according to the first or second aspect, wherein the cutter has a plurality of grater blades formed on a base integrally formed with the entire surface in contact with the food.

As a result, there is no gap generated when the cutter is fixed to another member, and juice and the like enter into this, and mold can be maintained without any mold.

According to a sixth aspect of the present invention, there is provided the juicer according to the first or second aspect, wherein a drain hole is provided in the bottom surface of the separation basket.

[0017] Thus, even if water or the like is spilled into the separation basket disposed on the main body, water can be prevented from spilling onto the main body from a gap between the cutter and the separation basket since water is drained from the drain hole. .
