Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposer that is disposed on a sink in a home or commercial kitchen and performs processing of garbage.
[0002]
[Prior art]
Conventionally, the suction casing constituting the main body of the garbage disposal disposer has been composed of a single part made of aluminum or synthetic resin.
[0003]
[Problems to be solved by the invention]
If the suction casing of the disposer is made of a synthetic resin, it is inexpensive and lightweight, but there are drawbacks such as poor wear resistance and transmission of the generated impact sound, causing noise. If this suction casing is made of metal, the problems of wear resistance and noise are solved, but it is heavy and expensive, and it has to be painted to keep the appearance beautiful. Further, in order to badge-treat a large amount of garbage, the suction casing preferably has a large capacity, while the fixed blade and the rotary blade must be made as small as possible to reduce the cost. Therefore, a suction casing having a large capacity at the top and a conical shape near the lower rotary blade has been devised, but there is a drawback that the structure is complicated to manufacture as a single part.
[0004]
[Means for Solving the Problems]
The present invention provides a garbage disposal disposer in which a tubular metal hopper is fitted inside a substantially cylindrical resin suction casing body so that the entire suction casing has a double structure and the outer surface of the hopper is sucked. A cylindrical surface that fits closely to the inner surface of the casing body, and a funnel-shaped inclined surface that swells downward on the inner surface of the hopper. There by to be placed, is obtained by solving the problems such as insufficient complicated structure and durability described above.
[0005]
The shape of the metal hopper can take any shape according to the capacity of the suction casing, the size of the cutting blade and their arrangement, but as an example, a cylinder that closely fits the outer surface of the hopper to the inner surface of the suction casing body The inner surface of the hopper is formed into a funnel-shaped inclined surface that swells downward, and the disposer fixed blade and the rotating blade are disposed on the lower inner side of the lower circumference of the funnel-shaped inclined surface.
[0006]
The hopper is made by punching out 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. By placing the hopper in metal and closely fitting the inner surface of the suction casing, it has better wear resistance than the resin suction casing alone, and the introduction of garbage to the crushing blade is smoother, resulting in noise. And less vibration.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention is shown in FIGS. The disposer 1 for garbage disposal has a garbage input port 2 and a garbage crushing part 3 in the upper part, a discharge blade 5 having a discharge port 4 in the lower part, a rotary blade 6 and an outer peripheral surface of the rotary blade 6. A fixed blade 7 and a drive device 8 for the rotary blade 6 arranged opposite to each other are arranged, and the garbage 9 is crushed by the hammer 9 and the fixed blade 7 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 body, and the entire suction casing 10 has a double structure.
[0008]
In one embodiment of the present invention, as shown in FIGS. 1 and 2, the suction casing 10 has a cylindrical surface 12 that closely fits the inner surface of the suction casing body, and the inner surface of the hopper faces downward. A funnel-shaped inclined surface 13 is formed, and the fixed blade 7 and the rotary blade 6 of the disposer are arranged on the lower inner side of the lower end circumference of the funnel-shaped inclined surface 13. The hopper 11 is formed by cutting out the inner surface of a thick metal cylinder into a funnel shape.
[0009]
As another embodiment of the present invention, the hopper 11 can be made by fitting a truncated cone into a thin cylindrical body and joining the upper end circumference. Furthermore, it is also possible to make the outer peripheral surface of the hopper 11 elastic and press-fit into the inner surface of the resin suction casing 10 so that they are closely fitted. For comparison with the present invention, FIG. 4 shows a disposer in which a conventional suction casing is composed of a single part made of aluminum or synthetic resin.
[0010]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
(1) Since the inner surface of the suction casing is formed into a funnel shape by a hopper, the garbage is supplied little by little to the crushing blade, so that the processing efficiency is good and noise and vibration are reduced.
(2) Since the suction casing is formed of a synthetic resin main body and a metal hopper, it is easy to manufacture and has excellent wear resistance during use.
(3) Rust prevention treatment of the hopper part is necessary, but since it is not known from the appearance, it is not necessary to apply finish coating in design.
