In the conventional kitchen storage device described above, the fan 4 operates at least when the door 1 is opened, and the storage box 3 is opened.
The internal odor was discharged to the sewer through the odor release pipe 8 and the exhaust pipe 7.

[0004]

However, in the above-mentioned conventional configuration, when the door 1 is opened and the kitchen waste is thrown into the storage 3, or while the door 1 is closed, the odor in the storage 3 is periodically set. Was drained back to the drain pipe 6 due to clogging of the sewage part, etc.
It sometimes overflowed into the storage 3. Also, the odor removal pipe 8
Some had a drainage check valve in the middle of the
In this case, although the backflow of the drainage was prevented, the user could not be notified because the backflow was not sensed, and at the same time, the fan 4 operated independently of the blockage due to the backflow, and thus the odor in the storage 3 was not detected. However, there was a drawback that it was not discharged to the outside air and overflowed into the kitchen space.

The present invention solves the above-mentioned problems, smoothly discharges odors during temporary storage, detects clogging of drainage and notifies the user, and at the same time suppresses backflow of odors to ensure comfort, It is an object to provide a kitchen storage device with reduced power loss.

[0006]

In order to solve the above-mentioned problems, the kitchen storage device of the present invention has the following constitution.

[0007] In the vicinity of the drain pipe of the sink, there is provided a storage box including a container for storing kitchen waste and a storage lid having an exhaust device having an exhaust pipe connected to the drain pipe so that air can communicate with the exhaust pipe. A drain check valve is installed in the drain, and a magnetic sensor in conjunction with the exhaust device and a permanent magnet are made to face the air flow near the lower end of the drain check valve, and a float with a magnetic shield at the bottom inside the check valve is provided. A valve body was provided.

In addition, near the drainage pipe of the sink, there is provided a storage box including a container for storing kitchen waste and a storage lid provided with an exhaust device having an exhaust pipe connected to the drainage pipe, and air is communicated in the exhaust pipe.

That is, a permanent magnet is made to face a magnetic sensor interlocking with an exhaust device near the lower end of the drainage check valve, and a float valve element having a magnetic shield at the bottom is provided in the drainage check valve. As a result, the float type valve body floats during drainage reverse flow, so the magnetic shield between the magnetic sensor and the permanent magnet is released, and the magnetic sensor detects the reverse flow, and it is possible to control the exhaust system to work with it. it can. Also,
When the backflow is eliminated, the center of gravity of the float type valve body is located in the lower magnetic shield, so that the magnetic shield is housed as before. Further, since the permanent magnet does not come into contact with moisture, it is not necessary to cover it.

Further, by providing a magnetic sensor interlocking with the exhaust device near the lower end of the drainage check valve and by providing a float type valve body having a magnetic radiator in the lower part in the drainage check valve, At the time of reverse flow, the float type valve body floats,

It fits with the magnetic radiator down like the original. Further, since the gap between the magnetic sensor and the magnetic radiator is small, the magnetic force may be weak.

Further, since the alarm device interlocking with the magnetic sensor is provided, it is possible to notify the user of the backflow situation.

Further, when the magnetic sensor detects a backflow, the exhaust device is stopped to prevent odor leakage from the storage due to the operation of the exhaust device when the drainage is clogged and to suppress unnecessary energization of the exhaust device. be able to.

Therefore, the odor can be smoothly discharged during the temporary storage of the kitchen waste, the clogging of the drainage can be sensed to notify the user, and at the same time, the backflow of the odor can be suppressed to ensure the comfort and the power loss. A kitchen storage device can be provided.

Embodiments of the present invention will now be described with reference to the drawings.

(Embodiment 1) In FIG. 1, reference numeral 1 is a sink, and a drain pipe 9 having an open upper end is provided at the bottom thereof. A waste drop port 10 and a drain port 11 are provided at the bottom of the drain pipe 9, a sluice valve 12 is provided at the lower part of the waste drop port 9, and a bowl trap 13 is provided at the lower part of the drain port 11. Further, inside the drainage tube 9, a draining tube 14 is provided which is inserted from the kitchen drop opening 10 at the upper end and is placed on the kitchen drop opening 10.
The draining cylinder 14 has no bottom surface and a plurality of holes 15 are opened on the side surface. Further, the sluice valve 12 is driven by the drive unit 16 as shown in FIG.

Further, a container 17 is provided immediately below the kitchen drop port 10, and a storage lid 18 on the upper part of the container 17 has an exhaust device 21 including a suction fan connected to an exhaust pipe 20 opening to a drain pipe 19. , And a notification device 22 including a neon lamp. A drainage check valve 23 is provided midway of the exhaust pipe 20, and a magnetic sensor 24 is provided at a position facing each other at an end of the drainage check valve 23 downstream of the exhaust air flow. A permanent magnet 25 is installed. On the other hand, drainage check valve 23
Inside, a hollow spherical float-type valve element 27 having a magnetic shield 26 formed by cylindrically molding a ferritic stainless steel thin plate in the lower portion is movably placed. The exhaust device 21 is linked with the notification device 22 and the magnetic sensor 24.

In the above structure, when the kitchen waste is thrown into the water draining cylinder 14, the water contained in the kitchen waste flows out through the hole 15 on the side surface of the water draining cylinder, and the drainage port 11 and the bowl trap 13 are provided.
Drained through. Furthermore, after the kitchen is thrown in, the drive unit 16
When the sluice is driven to open the sluice valve 12, the garbage is dropped from the garbage dropping port 10 by gravity and is stored in the container 17. After the kitchen waste drops, close the sluice valve 12 to drain the water.
Reference numeral 4 simply serves as a drainage passage, and water is guided to the sewage through the drainage port 11 and the trap 13.

On the other hand, when the garbage is dropped into the container 17, the exhaust device 21 operates in a certain time cycle, and the odor is discharged from the exhaust pipe 20 to the drain pipe 19 through the drain check valve 23. Normally, when the float-type valve body 27 is lowered, the magnetic shield 26 is present between the magnetic sensor 24 and the permanent magnet 25, and therefore the backflow is not judged, and the exhaust device 21 operates normally. On the contrary, as shown in FIG. 2, when the drainage flows backward and the float type valve body 27 floats, only the drainage is left between the magnetic sensor 24 and the permanent magnet 25, and the magnetic sensor 24 detects the magnetic field from the permanent magnet 25. The exhaust device 21 that senses the

On the other hand, in the drainage check valve 23a, a hollow spherical float-type valve body 27a having a magnetic radiator 28 made of a permanent magnet with a rust-proof coating at the bottom is movably placed. Similarly, the exhaust device 21 is linked with the notification device 22 and the magnetic sensor 24a.

In the above structure, the floating valve body 2 is usually used.
In the state in which 7a is lowered, there is the magnetic radiator 28 in the vicinity of the magnetic sensor 24a, so it is not judged that the backflow occurs, and the exhaust device 21 operates normally. On the contrary, when the drainage flows backward and the float valve body 27a floats, only the drainage is left in the vicinity of the magnetic sensor 24a, and the alarm device 22 is turned on by detecting the reverse flow, and at the same time, the associated exhaust device 21 is stopped. Control. Similarly, if the backflow is resolved,
Since the center of gravity of the float type valve body 27a is in the lower magnetic radiator 28, the floating radiator 27a is housed with the magnetic radiator 28 facing down. In this configuration, when the floating valve body 27a is lowered, the magnetic radiator comes very close to the magnetic sensor 24a, so that the original permanent magnet does not need a strong magnetic force.
A cheap magnet will do.
