BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device for crushing kitchen garbage and the like.

[0002]

2. Description of the Related Art Conventionally, as this type of garbage processing apparatus, one disclosed in Japanese Patent Laid-Open No. 2-359945 is known. That is, in this, a rotary plate driven by a rotary drive device such as an electric motor to receive the kitchen waste is provided in the main body having a kitchen throwing port formed in the upper part, and a cylindrical fixed blade surrounding the rotary plate is provided. Provided in the main body, rotatably pivoting a crushing tool composed of a cubic metal piece, a plate-shaped resin piece, or the like on the upper surface of the rotary plate so as to face the fixed blade, together with dirty water in the main body. After the thrown garbage is received by the rotary plate, it is struck by centrifugal force on the inner peripheral surface of the fixed blade, and is crushed by the impact crushing action of the crushing tool, and the crushed garbage is crushed by the inner surface of the fixed blade and the rotary plate. It is designed to be dropped from between the outer peripheral surface and discharged from the lower discharge port.

[0003]

However, according to the above-mentioned conventional structure, since the garbage is crushed only by the impact of the crushing tool of the metal piece, it is difficult to cut the garbage into pieces, and the crushing ability is limited. Further, it is difficult to obtain a strong impact force with a crushing tool for resin pieces.

On the other hand, instead of using the above-mentioned crushing tool, it is also known that a mixer blade-like tool is attached upward to cut off the garbage thrown from the garbage throwing port. When cleaning the inside, it is easy to get injured by accidentally touching the upward blade, which is unsafe for use.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a garbage disposal device which can improve the crushing ability and can clean the inside of the main body safely. I am trying.

[0006]

In order to achieve the above object, the present invention provides a rotary plate which is driven by a rotary drive device in a main body having an garbage throwing port formed in an upper portion thereof to receive the garbage from the garbage throwing port. And a crushing tool for crushing the garbage with a cylindrical fixed blade that surrounds the rotating plate and is fixed in the main body, and a crushing tool that is rotatably supported on the rotating plate. In the apparatus, a movable cutter protruding from a free end of the crushing tool by centrifugal force when the rotating plate rotates in a space formed in the crushing tool, and a return spring for retracting the movable cutter to a storage position when the rotating plate stops. And are arranged.

[0007]

According to the kitchen garbage processing apparatus having the above structure, when the rotation driving device is operated, the rotary plate and the crushing tool rotate. Then, the garbage thrown in with the waste water from the garbage throwing port flows down downward, is received by the rotating plate, is hit by the inner peripheral surface of the fixed blade by centrifugal force, and is crushed by the rotating crushing tool. On the other hand, when the rotary plate rotates, the movable cutter incorporated in the crushing tool projects from the free end of the crushing tool against the spring force of the return spring, so the kitchen waste is also cut by this movable cutter. Then, it falls downward between the outer peripheral surface of the rotary plate and the inner peripheral surface of the fixed blade and is discharged.

That is, since the impact crushing action by the crushing tool and the cutting action by the movable cutter are given to the garbage, the crushing effect is enhanced. Further, since the movable cutter is stored in the crushing tool when not in use, it is possible to prevent the cutter from accidentally injuring a hand when cleaning the inside of the main body.
