JPH07232095A - Garbage disposer - Google Patents

Abstract

PURPOSE:To provide a garbage disposer capable of reducing further the ground grain size of garbage. CONSTITUTION:A part of the outer peripheral part of a rotary blade 8 is formed projecting 10 in a radial direction, and all around the inner peripheral part of a fixed blade 9, a recessed part 11 corresponding to the projecting part 10 of the rotary blade. Consequently, the length of a cut face is increased by both the projecting part and the recessed part and thus garbage can be ground more finely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen waste processing apparatus for crushing kitchen waste discharged from a kitchen and flowing it into a sewer through a drainage pipe.

[0002]

2. Description of the Related Art FIG. 2 is a cross-sectional view of a conventional garbage disposal device, and FIG. 3 is a plan view of a main portion thereof. Reference numeral 1 denotes a casing of the garbage disposal device connected to a sink and having a conical hood. 2 and a cylindrical case 3 are connected by a connecting portion 4, and at the bottom of the casing 1, a waterproof housing 5 for hermetically housing a motor that is a rotation drive device is provided.

Inside the casing 1, a rotary disk 6 for receiving the thrown garbage is attached to a rotary shaft 7 of a motor so as to be rotatable around the axis of the rotary shaft 7. The rotary blade 8 is arranged on the upper surface. A ring-shaped fixed blade 9 having a blade formed in the vertical direction is provided on the inner peripheral surface of the casing 1 facing the rotary blade 8, and the rotary blade is rotated by the rotation of the rotary disc 6 driven by a motor. By rotating 8 the kitchen waste is crushed between the rotary blade 8 and the fixed blade 9.

[0004]

However, in the above-mentioned garbage treatment device, there is a problem that the drainage pipe and the sewer pipe are heavily loaded unless the garbage is finely crushed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a kitchen waste processing apparatus capable of making the crushed grain size of kitchen garbage smaller.

[0006]

In order to solve the above-mentioned problems, the kitchen waste disposal apparatus of the present invention is attached to the lower part of the sink, and the kitchen waste thrown in from above is crushed by a rotary blade and a fixed blade to sewer. Which is a garbage disposal device to be flown into the inside of the casing, a rotary disc for receiving the thrown garbage is provided rotatably by a motor, a rotary blade is arranged on the upper surface of the rotary disc, and the casing facing the rotary blade is provided. In a garbage disposal device in which a fixed blade is arranged on the inner peripheral surface of the rotary blade, a part of the outer peripheral portion of the rotary blade is formed in a convex shape by protruding in the radial direction, and the convex shape of the rotary blade is formed on the inner peripheral portion of the fixed blade. The concave portion corresponding to the portion is formed over the entire circumference.

[0007]

With the above structure, the convex portion of the rotary blade moves in the concave direction formed in the fixed blade in the circumferential direction, and the garbage has the cut surface length increased by the convex portion and the concave portion. It is crushed more finely by passing through.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of essential parts of a garbage processing apparatus according to an embodiment of the present invention. The kitchen waste processing apparatus of this embodiment is shown in FIG.
Since it is almost the same as the conventional garbage processing device described with reference to FIG. 3, illustration and description of the entire configuration will be omitted.
Members having the same configuration and the same action will be described with the same reference numerals.

The garbage treating apparatus of this embodiment is different from the conventional one in that the sharp blade 10 is formed substantially at the center of the outer peripheral portion of the rotary blade 8 in the radial direction, and the fixed blade 9 is formed.
A concave portion 11 corresponding to the convex portion 10 of the rotary blade 8 is provided on the inner peripheral portion of the
Is a point formed over the entire circumference.

With the above structure, the convex portion 10 of the rotary blade 8 is formed.
Moves in the circumferential direction while being positioned inside the concave portion 11 formed in the fixed blade 9, and the convex portion 10 and the concave portion 1
1 increases the length of the cut surface, and the sharp convex shape of the rotary blade 8 facilitates the crushing of kitchen waste. Therefore, when the kitchen waste is thrown in from above, the kitchen waste is received by the rotary disk 6 and crushed by the rotary blade 8 and the fixed blade 9, and finely crushed when passing between the convex portion 10 and the concave portion 11.

[0011]

As described above, according to the present invention, a part of the outer peripheral portion of the rotary blade is formed to project in the radial direction so as to be convex, and the inner peripheral portion of the fixed blade and the convex portion of the rotary blade are formed. By forming corresponding recesses over the entire circumference and increasing the length of the cut surface, the kitchen waste can be crushed more finely than before and flowed into the drain pipe.
