Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device,
In particular, it relates to a garbage disposal device provided in a drainage channel of a kitchen sink.

[0002]

2. Description of the Related Art For example, in a garbage disposal device disclosed in Japanese Patent Laid-Open No. 54-68073, a magnet is attached to a part of a lid attached to an garbage inlet, and the magnet is attached to a cylindrical portion of a main body. There is a method of driving the motor by facing the reed switch.

[0003]

In the case of this prior art,
It is necessary to mount the lid while aligning the magnet so that the magnet is close to the reed switch, and there is a concern that the motor may not be started if the position is displaced.

Further, as described in the text, the partition plate has a structure in which the water passage hole is closed at the position where the reed switch operates, so that the reed switch is closed during operation (during operation of the garbage disposal device). No water flows under the mouth.

Therefore, the kitchen waste crushed by the rotary blade scatters on the inner circumference of the tubular portion due to centrifugal force, and is hard to be discharged to the outside of the tubular portion while adhering to it, or it rots and gives off a bad odor. There is a risk of problems such as solidification by and blocking the operation of the rotary blade.

An object of the present invention is to improve the prior art so that the garbage processing device can be operated reliably even when the plug is randomly attached to the charging port, and the crushed garbage can be removed from the crushing mechanism portion. It is intended to smoothly discharge and prevent noise during crushing from leaking from the inlet.

[0007]

Means for Solving the Problems The kitchen waste disposal apparatus according to the present invention has an input port for food waste and a crushing mechanism driven by an electric motor, and a plug is attached to a passage extending from the input port to the crushing mechanism. A gap is formed between the plug body and the passage, and a narrow portion having a flow passage area narrower than that of the charging port is formed in the middle of the gap to fill the narrow portion with water flowing in when crushing food waste. Thus, the inflowing water shields the passage from the charging port to the crushing mechanism.

Further, an annular magnet is attached to the entire circumference of the plug body mounted in the passage extending from the charging port to the crushing mechanism, and an operation control element for the electric motor is provided at a position facing the magnet when the plug body is mounted. It is provided.

[0009]

[Function] When the water does not flow into the gap between the plug and the passage, the charging port and the crushing mechanism communicate with each other, and when the water flows in, the passage between the charging port and the crushing mechanism is shielded with water. To be done.

Even if the plugs are randomly attached to the charging port, any part of the annular magnet acts on the operation control element of the electric motor.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention, which is a kitchen waste disposal apparatus having an input port 4 for garbage and a crushing mechanism 8 driven by an electric motor 6 on the bottom surface of a sink 2 of a sink.

The input port 4 is watertight by sandwiching the sink 2 between the cylindrical body 10 and the annular body 12 via the annular packing 14.

Further, the plug body 16 is mounted inside the cylindrical body 10, and a gap 20 is formed between the plug body 16 and the cylindrical body 10.

In the gap 20, a narrow portion 22 having a flow passage area narrower than that of the charging port is formed in the passage 18 from the charging port 4 to the crushing mechanism 8. An annular magnet 24 is attached to the lower portion of the plug body 16. When the plug body 16 is attached to the cylinder body 10, the magnet 24 is used to control the operation of the electric motor 6 provided in the cylinder body 10. It is arranged so as to be close to the element 26 (a reed switch in this embodiment).

Further, a lid 28 can be mounted in a watertight manner on the insertion port 4 part.

Further, the crushing mechanism 8 is provided with a rotary blade 30 and a fixed blade 32 directly connected to the electric motor 6.

Below the crushing mechanism 8, a discharge path 34 for crushed kitchen waste is provided. Next, the driving operation of this embodiment will be described.

First, the stopper 16 and the lid 28 are removed,
When the garbage is put in the charging port 4 and the plug 16 is attached to the cylindrical body 10 while water is flowing from the nearby faucet, the magnet 24 acts on the element 26 to start the electric motor 6.

Here, the electric circuit of the electric motor 6 will be described with reference to FIG.

The electric motor 6 and the power source 40 are connected by an electromagnetic switch 42.
Are connected in series via.

Here, the excitation circuit 42A of the electromagnetic switch 42
Is constituted by connecting the excitation winding 42B and the reed switch 42C in series.

When the magnet 24 approaches, the reed switch 42C closes the contact, and the power source 40 and the excitation winding 42B.
The closed circuit is formed, and the excitation winding 42B closes the contact 42D of the electric motor 6 circuit to start the electric motor 6.

As described above, since the electric motor 6 does not start unless the plug 16 is attached, it is possible to prevent troubles such as careless insertion of the hand through the charging port 4 and injury at the crushing mechanism 8.

Further, since the annular magnet 24 is attached to the entire circumference of the plug body 16, even if the plug body 16 is randomly attached to the charging port 4, the reed switch can be operated at any portion of the annular magnet 24.
Since it acts on 42C, the garbage processing device can be reliably started.

On the other hand, the garbage that has been pushed into the passage 18 by the plug 16 drops into the crushing mechanism 8 together with the water injection, and after being crushed, flows smoothly into the discharge passage 34 together with the water.

During the crushing of the garbage, the injected water fills the narrow portion 22, and the crushing mechanism 8 is fed from the charging port 4.
Since the passage 18 leading to is continuously blocked with water, noise during crushing is suppressed from leaking from the inlet 4, and silent operation can be performed.

On the other hand, the gap 2 between the plug body 16 and the cylindrical body 10
When water does not flow into 0, the charging port 4 and the crushing mechanism 8
And the rotation sound of the crushing mechanism 8 part is in communication with the input port 4
Since it can be heard in a proper size, it gives an alarm when the user forgets to inject water during crushing, and has the effect of alerting the user.

[0028]

EFFECTS OF THE INVENTION According to the present invention, even if the plugs are randomly attached to the charging port, the garbage processing device operates reliably, and the crushed garbage is smoothly discharged from the crushing mechanism section, and noise during crushing is input. It is possible to obtain a practical garbage disposal that can suppress leakage from the mouth.
