Description

[Detailed Description of the Invention] The present invention relates to an automatic grater that grinds radish, yam, etc. using a rotor-type grater rotated by a motor.

Conventional automatic graters of this type have a structure in which a grater disk with many small protrusions protruding from its surface is installed horizontally in a case, and the disk is attached to the rotating shaft of a motor. The radish is grated by pressing it against a rotating grater disk.

However, since the direction of pressing the radish etc. is perpendicular to the plane of rotation of the grater disk, a large amount of pressing requires force, making it difficult for women and girls to use it for long periods of time.

Furthermore, the ground radish and other ground chips grated by the grater are scattered by the centrifugal force of the rotating disk, and are brought out to the outlet. Then it returns to the disk.

As a result, the protrusions on the disc become clogged with scraps, resulting in a disadvantage that the grating efficiency gradually decreases.

Furthermore, it is structurally troublesome to assemble and disassemble the case and the grater disk, and cleaning operations, which are especially important in food processing machines, cannot reach every nook and cranny, resulting in unsanitary conditions.

This invention attempts to eliminate the above-mentioned drawbacks.
The purpose is to provide an automatic grater that can quickly grind radish and the like without requiring almost any force when pressing on the radish to be grated, and that is easy to clean.

The present invention will be described in detail with reference to the illustrated embodiment. In the figure, 1 is a motor case, 1a is a motor flange fixed to the case, 2 is a leg stand, and the leg stand 2 is attached to both sides of the lower surface of the motor case 1. After fixing, bend and attach the motor flange 1a.
It protrudes from the side.

3 is a power cord, and 4 is a power switch.

In FIG. 3, the motor 5 is housed in the motor case 1 by being fixed to the motor flange 1a,
The rotating shaft 5a passes through the motor flange 1a, projects horizontally to the outside, and has parallel chamfers formed on its outer periphery.

6 is a cooling fan for the motor 5, and 7 is a capacitor.

Reference numeral 8 denotes a rotor blade to serve as a grater, and a large number of protruding blades are protruded from the outer peripheral surface 9 of the rotor blade 8, as shown in FIG.

This protruding blade 10 can be made by making a hole in the rotor 8' itself with a knife, by making a hole in a metal plate with a press or the like and wrapping it around the outer circumference of the rotor 8', or by punching out a part of the metal plate. There is a method in which teeth are formed by raising the portions that have been raised, and the teeth are wound around the outer circumference of the rotor 8', and any method may be used.

The rotor blade 8 configured as described above has a cylindrical shaft 11
After inserting the center hole 11a into the rotating shaft 5a of the motor 5, the male screw 12 screwed onto the cylindrical shaft 11 so as to be rotatable is tightened to removably fix it to the rotating shaft 5a. However, separate seats 13. are provided at the front and rear ends of the cylindrical shaft 11.
13 is attached, and its center hole 13a is connected to the rotating shaft 5.
The rotor blade 8 is formed in an oblong hole so as to be in close contact with the chamfered portion a, so that the rotor blade 8 cannot rotate with respect to the rotating shaft 5a.

14 is a rotor blade case; On the top of the
A hopper 15 is provided for feeding grated material A such as radish, and its bottom and side surfaces are opened, and the bottom opening in particular is a discharge port 1 for grated scraps.
It is 6.

Reference numeral 17 indicates a receiving tube, and the receiving tube 17 is fixed at both upper corners of the rotor blade case 14 toward the side opening side, and 18 is a receiving tube 17. This is a tightening screw that is rotatably screwed into the rotor blade case 14 from the outside.

A guide rod 19 is inserted into the receiving tube 17, and the guide rod 19 projects from the motor flange 1a.

Therefore, the rotor blade case 14 is installed by inserting the guide rod 19 into the receiving tube 17 and bringing the side opening of the rotor blade case 14 into close contact with the motor flange 1a.
It is fixed to the motor case 1 by tightening 8.

Here, the center X of the hopper 15 is the center Y of the rotor blade 8.
Rather than being aligned with the rotor blade 8, it is attached to the top surface of the rotor blade case 14 with a slight shift in the rotational direction of the cylindrical blade 8. When pressed, grated material A can be ground without applying force.

The automatic grater according to the present invention has a motor case 1 and a rotor blade case 14 as described above. Since the rotating shaft 5a of the motor 5 and the rotor blade 8 are configured to be removable,
It is easy to assemble and disassemble, and it is easy to clean, which is especially important for food processing machines, and it is hygienic because it can be used in a clean state at all times.

In addition, a hopper 15 is provided upright on the upper surface of the rotor blade case 14, and the center X of the hopper 15 is offset from the center Y of the rotor blade 8 in the rotation direction.
The radish and the like are pulled into the hopper 15 by the protruding blade 10 in the direction of rotation of the rotor blade 8, and therefore only a small amount of force is required to press the radish against the grated item.

For example, in the case of a soft material such as a yam, there is no need to press it, and it can be automatically lowered by simply placing it in the hopper 15.

Moreover, at least the lower end of the hopper 15 on the side in the direction of deflection hangs down into the rotor blade case 14 and is brought close to the outer periphery of the rotor blade 8, so that the grated material is not crushed and reduced in size. Also this is hopper 15
It can be stopped by the bottom edge of the holder to prevent it from falling down.
Therefore, even small items can be safely grated to the last drop, resulting in the effect that no waste occurs.
