Abstract

<P>PROBLEM TO BE SOLVED: To improve abrasion resistance of a disposer for treating a wet refuse and to decrease a noise. <P>SOLUTION: In the disposer for treating the wet refuse, a suction casing body is wholly made into a double structure by fitting a tubular metal hopper to the inside of a nearly cylindrical resin-made suction main body. An outside surface of the hopper is made to be a cylindrical surface fitted closely to the inner surface of the suction casing main body and an inner surface of the hopper is made to be funnel-shaped inclined surface narrowing downward. A fixed blade and a rotary blade of the disposer are constituted so as to be arranged downward inside a lower end circumference of the funnel-shaped inclined surface. The hopper is prepared by gouging out an inner surface of a thick-walled metallic cylindrical body in a funnel-shape. As another example, the hopper can be also prepared by fitting a truncated cone to a thin-walled cylinder to be joined at an upper end circumference. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer which is disposed on a sink of a domestic or commercial kitchen to treat raw garbage.

[0002]

2. Description of the Related Art Conventionally, a suction casing constituting a main body of a garbage disposer has been constituted by a single component made of aluminum or synthetic resin.

[0003]

When the suction casing of the disposer is made of synthetic resin, it is inexpensive and lightweight, but it has poor wear resistance and causes the sound of impact to be generated, which causes noise. There was a drawback. If the suction casing is made of metal, the problems of abrasion resistance and noise can be solved, but it is heavy and expensive, and it is necessary to paint it in order to keep its appearance beautiful. Further, in order to perform a badge treatment of a large amount of garbage, it is preferable that the suction casing has a large capacity, while the fixed blade and the rotary blade are made as small as possible to reduce the cost. Therefore, a suction casing was devised in which the upper portion has a large capacity and the lower rotary blade is squeezed into a cone shape, but there is a drawback that the structure becomes complicated to manufacture it as a single part.

[0004]

According to the present invention, in a garbage disposer, a tubular metal hopper is fitted inside a substantially cylindrical resin suction casing body,
By making the entire suction casing a double structure, the problems such as the above-mentioned complicated structure and insufficient durability are solved.

The shape of the metal hopper can be any shape according to the capacity of the suction casing, the size of the cutting blades and their arrangement. As an example, the outer surface of the hopper is closely fitted to the inner surface of the suction casing body. Molded so that the inner surface of the hopper is a funnel-shaped inclined surface that narrows downward, and the fixed blade and rotating blade of the disposer are located inside the lower end circumference of the funnel-shaped inclined surface. To do.

The hopper is made by hollowing the inner surface of a thick metal cylinder into a funnel shape, but it can also be made by fitting a truncated cone into a thin cylinder and joining the upper circumference. it can. By making the hopper made of metal and tightly fitted to the inner surface of the suction casing, it has better abrasion resistance than the resin suction casing alone, and the introduction of raw dust to the crushing blade is smooth and noise is reduced. Also, the occurrence of vibrations is reduced.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention is shown in FIGS. The food waste disposer 1 has a food waste input port 2 and a food waste crushing unit 3 at the upper part, and a discharge casing 5 having a discharge port 4 at the lower part, a rotary blade 6 and an outer peripheral surface of the rotary blade 6. Fixed blade 7 and rotary blade 6 arranged to face each other
The driving device 8 is disposed, and the hammer 9 and the fixed blade 7 grind the garbage according to the rotation of the rotary blade 6. In the disposer 1 of the present invention, a tubular metal hopper 11 is fitted inside a substantially cylindrical resin suction casing 10 main body, and the suction casing 10 as a whole has a double structure.

In one embodiment of the present invention, as shown in FIGS. 1 and 2, the suction casing 10 has a cylindrical surface 12 whose outer surface is closely fitted to the inner surface of the suction casing main body, with the inner surface of the hopper facing downward. The funnel-shaped inclined surface 13 is narrowed toward the bottom, and the fixed blade 7 and the rotary blade 6 of the disposer are arranged inside the lower end circumference of the funnel-shaped inclined surface 13. The hopper 11 is formed by hollowing out the inner surface of a thick metal cylinder into a funnel shape.

As another embodiment of the present invention, a hopper 1
1 can also be created by fitting a truncated cone into a thin-walled cylinder and joining the top circumference. Further, it is also possible to make the outer peripheral surface of the hopper 11 elastic and press-fit it into the inner surface of the suction casing 10 made of resin to tightly fit both. For comparison with the present invention, FIG. 4 shows a conventional disposer in which the suction casing is made of a single component made of aluminum or synthetic resin.

[0010]

Since the present invention is constructed as described above,
The following operational effects are achieved. (1) Since the inner surface of the suction casing is formed into a funnel shape by the hopper, the raw dust is gradually supplied to the crushing blade, so that the processing efficiency is good and the noise and vibration are reduced. (2) Since the suction casing is formed of the synthetic resin main body and the metal hopper, it is easy to manufacture and has excellent abrasion resistance during use. (3) It is necessary to prevent the hopper from rusting, but it is not necessary to apply a finish coating in design because it is not visible from the outside.
