It is in.

[0009]

FIG. 1 shows an embodiment according to the present invention.

In FIG. 1, the kitchen waste disposal apparatus has a food waste inlet 4 and a crushing means 8 driven by an electric motor 6 on the bottom surface of the sink 2 of the sink.

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

A cylindrical inner cylinder 15 with a bottom is mounted from above the cylindrical body 10, and a plug 16 is mounted on the input port 4, and a small gap 20 is provided between the plug 16 and the internal cylinder 15. Is formed.

An annular magnet 2 is provided below the plug 16.
4 is provided, and when the plug 16 is attached to the input port 4, the magnetic force of the magnet 24 is applied to the electric motor 6 provided in the cylinder 10.
, Which act on the element 26 (reed switch in this embodiment) of the proximity switch for operation control to start the operation by connecting the drive circuit of the electric motor 6 to the power supply.

The crushing means 8 provided at the bottom of the inner cylinder 15 is a disk which is slidably and detachably connected to the rotating shaft 6A of the electric motor 6 in the axial direction by a shaft coupling structure 28 such as a spline coupling. A rotary blade 30 is rotatably mounted on the rotary shaft 29 and a fixed blade 32 formed in the inner cylinder 15 in a slit shape.

Here, the disk 29 is supported on the bottom of the inner cylinder 15 via a bearing 33.

The housing 34 to which the motor 6 is attached is
It is attached to the lower part of the cylinder 10.

An opening 15A having a screen is provided in the inner cylinder 15 upstream of the crushing means 8, and when a large amount of cooking wastewater flows in, it is bypassed from above the crushing means 8 to directly At the outlet 36, and drains quickly.

Further, a water sealing section 38 is provided in the discharge path 36 downstream of the crushing means 8. This water sealing section 38
The inner cylinder 40 opening above the discharge path 36 is
Is mounted detachably via an annular sealing body 44, and the upper opening of the outer cylinder 42 is closed with a lid 50 via a sealing body 48;
By connecting the lower opening of the outer cylinder 42 to the drainage channel 52, the crushing device 8 and the drainage channel 52 are shielded by water sealing on the downstream side of the crushing device 8.

Here, a recess 40B is provided at the bottom of the rising portion of the inverted U-shaped flow path downstream of the inlet 42A into the water sealing portion 38 of the inner cylinder 40.

By collecting shells and egg shells that are difficult to flow into the recess 40B, clogging in the downstream drainage channel 52 can be suppressed, and the inner cylinder 40
Can be easily taken out of the recess 40B.

As shown in FIG. 2, when the inner cylinder 40 is taken out from the outer cylinder 42, when the inner cylinder 40 is pulled upward, the inflow port 40A of the inner cylinder 40 and the drainage channel 52 are discharged. It is configured to communicate through a path 36.

Therefore, the water stored in the water sealing portion 38 of the inner cylinder 40 is drained to the drainage channel 52, so that the inner cylinder 40 is
No sewage flows into the kitchen when removed from the kitchen.

Next, the operation of this embodiment will be described.

First, the plug 16 is removed, the garbage is put into the inner tube 15 through the input port 4, and the plug 16 is attached while flowing water from a tap nearby.
To close the electric circuit of the electric motor 6 to start the crushing operation.

Since the electric motor 6 does not start unless the plug 16 is mounted, the crushing means 8 is
This prevents problems such as injury.

Further, since the magnet 24 attached to the plug 16 is annular, even if the plug 16 is randomly attached to the input port 4, an arbitrary portion of the annular magnet 24 acts on the element 26.
The start of the kitchen waste disposal device can be performed reliably.

On the other hand, the garbage falls into the crushing means 8 along with the water injection, and after being crushed, flows down smoothly to the discharge path 36 together with the water.

Here, since the crushing means 8 is located below the water surface of the water sealing section 38, the crushing sound caused by crushing in water can be reduced.

Further, during the crushing of kitchen waste, the injected water fills the small gap 20 and continuously blocks the passage from the input port 4 to the crushing means 8 by pouring water. Leakage from the inlet 4 is suppressed, and silent operation is possible.

When water is not flowing into the small gap 20 between the plug 16 and the inner cylinder 15, the input port 4 and the crushing means 8 are in communication with each other, and the crushing sound of the crushing means 8 is reduced. Input port 4
Since the sound can be heard at an appropriate size, an alarm can be provided when the user forgets to inject the water at the time of crushing, and the user is alerted.

An element 26 of a proximity switch for controlling the operation of the electric motor by approaching the magnet 24 provided on the plug 16.
Is provided outside the inner cylinder 15 and the inner cylinder 15 is formed of a non-magnetic material, so that the crushing means 8 is automatically operated when the plug 16 is removed without adversely affecting the opening / closing operation of the proximity switch. Can be stopped and used safely.

Further, the outer diameter of the inner cylinder 15 provided with the crushing means 8 is configured to be smaller than the inner diameter of the input port 4,
The inner cylinder 15 can be taken out from the container, so that it is possible to easily and safely release the crushing means 8 when the crushing means 8 is locked with a solid material, and take out tableware such as a spoon or foreign matter that has been accidentally thrown in. .

If the inner cylinder 15 is constructed so that it can be divided into upper and lower parts near the crushing means 8, it is easier to release the lock and take out the foreign matter.

When the taken-out inner cylinder 8 is mounted downward from the inlet 4 again, the disc 29 and the rotating shaft 6A of the electric motor 6 are connected again by an axial joint structure 28 such as a spline joint which is detachable in the axial direction. Is done.

[0035]

As described above, according to the present invention, it is possible to easily and easily take out a solid matter that easily stays in the water sealing portion and to take out a foreign matter when the foreign matter is accidentally introduced into the crushing means.
It is possible to obtain a practical garbage disposal device with good handling properties such as safe removal.
