Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer attached to a garbage inlet of a disposer which is attached below a sink drain of a sink installed in a kitchen and crushes garbage (residues such as vegetables and fish). Pertaining to eye plates.

[0002]

2. Description of the Related Art A disposer is installed under a kitchen sink, and garbage and other garbage discharged from the sink are crushed into small pieces while flowing together with water (or may be drained), and then discharged to drain pipes and drains. It has a structure in which garbage is crushed by a rotating blade and a fixed blade rotating at high speed in a cylindrical crushing chamber.

Japanese Patent Laid-Open Publication No. Hei 8-299 discloses that the activation of the disposer is linked to the mounting operation of the eye plate.
No. 832 discloses a disposer.
This publication discloses a structure in which a permanent magnet is attached to a perforated plate and a reed switch that is turned on by the magnetic force of the permanent magnet is provided near the garbage inlet of the disposer body. Thus, the garbage crushing operation is automatically started when the eye plate is attached to the garbage trash inlet.

[0004]

However, since the perforated plate used conventionally has an opening which opens radially to supply water to the crushing chamber, the crushing sound and the drainage during crushing. Noise such as sound reaches the user through the opening and gives discomfort. In addition, it is possible to form a water film at the opening of the plate with the supplied water to reduce noise, but a large amount of water is required for forming the water film, which is uneconomical. In addition, if the area of the opening of the perforated plate is reduced in order to facilitate the formation of a water film, the amount of supplied water is reduced, and there is also a problem that the water required for transportation is not sufficiently supplied.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has an object to provide a disposer eye plate having a simple structure and capable of reducing noise generated from the disposer by supplying an appropriate amount of water. The purpose is to provide.

[0006]

Means for Solving the Problems The invention according to claim 1 of the present application (the present invention 1) is a dish for a disposer to be attached to a trash input port of a disposer, wherein the dish is parallel to a bottom plate portion of the dish body. This is a disposer eye plate provided with a thin plate similar in shape to the bottom plate portion.

The invention described in claim 2 of the present application (Invention 2)
Is a perforated plate for a disposer according to the first aspect of the present invention, wherein a distance between the bottom plate portion and the thin plate is 2 to 15 mm.

The invention described in claim 3 of the present application (the present invention 3)
Is that the surface area of the thin plate is 75 to 125 of the bottom plate area.
% Of the disposer eye plate of the present invention 1 or 2 of the present invention.

[0009]

According to the present invention, when the garbage is pulverized while being attached to the garbage inlet of the disposer, a thin plate having a similar shape to the bottom plate portion is provided in parallel with the bottom plate portion of the eye plate body. Is provided, water that has passed through the opening of the plate due to water supply always passes on the thin plate attached in parallel with the bottom plate, so that a water film is easily formed, and crushing noise, draining noise, etc. Noise will be reduced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an entire disposer to which a disposer plate according to the present invention is attached. This disposer basically includes a bottomed cylindrical casing 1 and a garbage crusher 2. A garbage crushing chamber 3 is provided at an upper portion of the casing 1. A discharge chamber 4 for crushed garbage is provided at a lower portion, and a crusher 2 is disposed at a boundary between the crushing chamber 3 and the discharge chamber 4 in the casing 1.

At the upper end of the casing 1, there is provided an input port 11 for inputting garbage into the crushing chamber 3, and the input port 11 is connected to the inner bottom of the sink via a connecting member 5, and
Garbage can be put into the crushing chamber 3 from inside the sink. A discharge chamber 4 is provided at the lower part of the outer peripheral wall of the casing 1.
A discharge port 41 for discharging the crushed garbage flowing into the inside to the outside is provided, and a discharge pipe 6 extending from a wastewater treatment device (not shown) can be connected to the discharge port 41. .

On the other hand, the crusher 2 comprises a disk-shaped turntable 21, a pair of swing hammers 22 pivotally supported on the upper surface of the turntable 21, and a casing 1.
And the annular fixed teeth 23 provided on the inner peripheral surface opposite to the outer peripheral surface of the turntable 21. The garbage dropped on the turntable 21 by the rotation of the turntable 21 mainly removes the garbage from the swing hammer 22. It can be ground with the fixed teeth 23.

The turntable 21 of the crusher 2 described above.
Is fixed to a drive shaft 25 of a motor 24 attached to a lower portion of the casing 1 so as to be able to rotate by driving the motor 24. The motor 24 is automatically driven and crushed when the metal detector 7 attached to the outer periphery of the connecting member 5 detects the mounting of the eye plate 13. In the figure, reference numeral 12 denotes a water stop lid.

FIG. 2 is a sectional view showing an example of a disposer eye plate according to the present invention, and FIG. 3 is a plan view thereof. FIG.
As shown in FIG.
The disposer 1 shown in FIG. As shown in FIG. 2 and FIG. 3, the disposer eye plate 13 is
a, a thin disk 132 similar in shape to the bottom plate 131a.
Is provided. A large number of openings 131b for supplying water to the crushing chamber are provided in the bottom plate 131a of the perforated plate body 131.
Are provided radially. The thin disk 132 has
No opening is provided.

The distance between the bottom plate 131a and the thin disk 132 is preferably 2 to 15 mm. If this interval is less than 2 mm, the supply amount of water decreases, and
If it exceeds m, formation of a water film becomes difficult. Thin disk 132
Is preferably 75 to 125% of the area of the bottom plate 131a. If this area is less than 75%, the formation of a water film becomes difficult, and if it exceeds 125%, it is necessary to increase the inner diameter of the crushing chamber 3 or the gap between the crushing chamber 3 and the water decreases. Or the supply of water may decrease.

Using this disposer eye plate 13,
The garbage is crushed as follows. As shown in FIG. 1, first, the power supply of the disposer is turned on, the water stop lid 12 and the perforated plate 13 are removed, and then the garbage is put into the crushing chamber 3 from the input port 11, and then water is supplied (water supply amount). 8 liter / min).

Next, a perforated plate 13 is attached to the refuse input port 11 of the disposer, and the refuse input port 11 is closed by the water stop lid 12. The metal detector 7 detects the mounting of the perforated plate 13 and the motor 24 is automatically driven to start crushing. At this time, the water that has passed through the perforated opening due to water supply always passes on the thin disk 132 attached in parallel with the bottom plate 131a, so that a water film is easily formed, and crushing noise, draining noise, etc. Noise will be reduced.

[0018]

The disposer eye plate of the present invention is constructed as described above, so that it can be easily mounted on the garbage inlet of the disposer to reduce the noise generated from the disposer by supplying a proper amount of water. And the structure is simple and the price is low.
