Abstract

PROBLEM TO BE SOLVED: To crush garbage in a short time by providing a disposer with a hopper which forms the peripheral side wall of a crushing chamber, providing the hopper with a step part and forming its upper-part into the shape narrowed with the step part as a boundary. SOLUTION: The hopper 15 is provided with the step part 16 at the position where is above and adjacent to a fixed blade 3 and is formed into the shape narrowed in an upper part with the step part 16 as the boundary. When a motor 1 is activated to operate a rotary plate 6, the thrown-in garbage is pushed to the fixed blade 3 by centrifugal force by the rotary movement of hammers 7 and 8. Movement is stopped by a groove in a part where the garbage is abutted on the fixed blade 3 and rotation is executed by the hammers 7 and 8 in the part where it is not abutted on the fixed blade 3 so that the garbage is cut here. The garbage is moved upwards by this shock. But the garbage is restricted by the step part 16 so that it is kept in the neighborhood of the fixed blade 3. Thus, the garbage is crushed in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer in which a hopper forms a peripheral side wall of a crushing chamber.

[0002]

2. Description of the Related Art In general, a disposer is provided below a sink of a sink to crush garbage and flow the sewage to the sewage. Local governments have banned the use of disposers.

Recently, however, a system has been developed that does not burden the sewage treatment facility, such as treating kitchen waste crushed by a disposer in a septic tank and then pouring it into sewage or composting the garbage so that the disposer can be used. It has become to.

[0004] A conventional disposer will be described below with reference to the drawings. FIG. 3 is a side sectional view of a conventional disposer, and FIG. 4 is a transverse sectional view of the disposer.

[0005] As shown in the figure, the disposer includes a motor 1, and an annular fixed blade 3 is provided on the inner peripheral side of the upper end of a bracket 2. A groove 9 is formed inside the fixed blade 3. In addition, a hopper 4 having a substantially conical shape that covers the fixed blade 3 and forms a peripheral side wall of the crushing chamber is provided on an upper portion of the bracket 2.

In the main body of the disposer, a rotary plate 6 is attached to the end of the shaft 5 of the motor 1 so that the hammers 7 and 8 can be rotated on the rotary plate 6 so as to face the fixed blade 3. Attached.

A charging port 10 is formed in the upper part of the hopper 4, and a lid 11 is detachably provided on the charging port 10. The disposer is then mounted on the sink by connecting the upper end of the hopper 4 to the sink bottom 12 of the sink.

In FIG. 3, reference numeral 13 denotes a discharge port, and reference numeral 14 denotes a water tap. The operation of the conventional disposer configured as described above will be described below.

First, garbage is thrown in from the slot 10 of the disposer, and the lid 11 is attached to the slot 10. Next, the motor 1 is started while the tap faucet 14 is opened and water is flowing, and the rotating plate 6 is rotated. Then, the hammers 7 and 8 rotate together with the rotary plate 6, and the tips of the hammers 7 and 8 face the inner surface of the fixed blade 3 due to centrifugal force. The thrown garbage is pressed against the fixed blade 3 by centrifugal force generated by the rotating motion of the rotating plate 6 and the hammers 7 and 8. The portion of the garbage that hits the fixed blade 3 is stopped by the groove 9, and the portion that does not hit the fixed blade 3 is rotated by the hammers 7 and 8. 13 to be discharged.

[0010]

However, in the structure of the conventional disposer, since the hopper 4 has a substantially conical shape, when the garbage is sheared by the fixed blade 3 and the hammers 7, 8, the garbage can escape upward. And the crushing time is relatively long. In particular, when processing garbage crushed by a disposer in a septic tank or the like, the load on the septic tank or the like can be reduced by crushing the garbage as finely as possible and clogging of the piping can be prevented, but the crushing granularity of the garbage is reduced. Requires that the groove 9 of the fixed blade 3 be small, and as a result, the crushing time is further increased.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a disposer capable of crushing garbage in a short time.

[0012]

According to the present invention, there is provided a disposer having a structure in which a hopper forms a peripheral side wall of a crushing chamber, wherein the hopper has a stepped portion, It is formed in a shape in which the upper part is squeezed at the boundary.

According to the present invention, it is possible to realize a disposer in which kitchen waste is effectively crushed and the crushing time can be shortened.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention has a configuration in which kitchen garbage is crushed by a hammer provided on a rotary plate and a fixed blade disposed outside the hammers, and the periphery of a crushing chamber is provided. A hopper that forms a side wall, the hopper has a stepped portion, and is a disposer formed in a shape in which the upper portion is narrowed at the stepped portion, and when the garbage is sheared by the fixed blade and the hammer. Escape upward is suppressed by the step portion of the hopper, and the crushing time can be shortened.

An embodiment of the present invention will be described below with reference to the drawings. (Embodiment 1) FIG. 1 is a side sectional view of a disposer according to Embodiment 1 of the present invention, and FIGS. 2A and 2B are a sectional view and a bottom view of a hopper in the disposer. The same components as those of the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

1 and 2, reference numeral 1 denotes a motor, 2
Is a bracket, 3 is a fixed blade, 5 is a shaft, 6 is a rotating plate, 7 and 8 are hammers, 10 is a slot, 11 is a lid, 12
Is a bottom of the sink, 13 is an outlet, and 14 is a tap for water supply.

The disposer according to the first embodiment has a feature in the configuration of the hopper 15 forming the peripheral side wall of the crushing chamber. That is, the hopper 15 is above the fixed blade 3 and close to the fixed blade 3. A step portion 16 is provided at the position where it is located, and the upper portion is narrowed at the boundary of the step portion 16. A rib 17 is provided below the step 16.

The operation of the disposer of the first embodiment configured as described above will be described below.

First, kitchen garbage is thrown in from the slot 10 and the lid 1
1 is attached. Next, the motor 1 is started while the tap faucet 14 is opened and water is flowing, and the rotating plate 6 is rotated. Then, the hammers 7, 8 rotate together with the rotary plate 6, and the tips of the hammers 7, 8 face the inner surface of the fixed blade 3 due to centrifugal force. The thrown garbage is pressed against the fixed blade 3 by centrifugal force generated by the rotating motion of the rotating plate 6 and the hammers 7 and 8. The portion of the garbage that hits the fixed blade 3 is stopped by the groove 9, and the portion that does not hit the fixed blade 3 is rotated by the hammers 7 and 8, so that the garbage is sheared here. Although the kitchen waste tends to escape upward due to the impact at this time, the kitchen waste stays near the fixed blade 3 because it is suppressed by the step portion 16. Also, the step portion 1
Since the rib 17 is provided below 6, turning of the garbage can be prevented. In this way, the kitchen waste is finely crushed and discharged from the discharge port 13.

[0020]

As is apparent from the above description, the disposer of the present invention has a shape in which the hopper forming the peripheral side wall of the crushing chamber has a step, and the upper part is narrowed at the step. Therefore, the garbage can be prevented from escaping upward due to the impact of shearing, and the garbage can be crushed in a short time.
The effect is great.
