DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage storage device.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional kitchen garbage storage device is of a type installed near a kitchen sink, and a storage space 3 is provided in a space formed by a door 1 and an outer shell 2. An odor suction fan 4 is provided, and an exhaust port 5 of the fan 4 is connected to a drain pipe 6 by a double pipe type exhaust pipe 7 and an odor release pipe 8, and the end of the exhaust pipe 7 is connected to the drain pipe 6. Similarly, there was an opening in the sewage section 9 (for example, Japanese Utility Model Publication No. 1-30412).

[0003] In the above-described conventional kitchen garbage storage device, at least when the door 1 is opened, the fan 4 operates and the storage garbage 3 is opened.
The odor in the interior is discharged to the sewage section 9 through the odor release pipe 8 and the exhaust pipe 7, and no odor is emitted inside the house.

[0004]

However, in the above-mentioned conventional construction, in summer or the like, the odor overflows from the sewage section 9 and rises, causing troubles with neighbors, and mice and pests from the sewage section 9. In many cases, the gas enters the storage through the exhaust pipe 7 and the odor release pipe 8. Furthermore, clogging at the outlet of the drain pipe 6 due to residual fluid or the like extends to the exhaust pipe 7, which sometimes makes it difficult to suck odor. There is also a construction problem of installing the exhaust pipe 7 in the drain pipe 6 in the form of a double pipe.

[0005] The present invention solves the above problems, efficiently deodorizes the whole while always maintaining an appropriate deodorizing ability, and discharges odorless and harmless air indoors and outdoors. It aims to provide a kitchen waste storage device.

[0006]

According to the present invention, in order to achieve the above object, a storage chamber is formed by an outer shell housing a container having an open upper surface, and a door holding one end of the container.
On the surface facing the opening of the container, an odor sensor, an exhaust pipe communicating with the outside from the opening of the container, and an ozone generating device interlocked with the odor sensor having one end communicating with the outside of the outer shell were provided. A discharge pipe is provided, an ozone decomposition catalyst or both an ozone decomposition catalyst and a deodorization catalyst are provided in the exhaust pipe, and a deodorizer provided with a heater which is interlocked with the odor sensor is provided on the outer periphery, and is provided downstream of the deodorizer. A suction device including a fan is provided, and a switch for stopping the ozone generation device and operating the fan when the door is opened is provided at a contact portion between the door and the outer shell.

[0007]

According to the present invention, the ozone-containing air injected into the container from the ozone generator through the discharge port when the door is closed is turned into sterilizing air when the door is closed. While sterilizing fungi and other microorganisms and decomposing odors at the same time, it flows into the exhaust pipe provided in the door and passes through the deodorizer, where residual ozone is decomposed and discharged outside the house as odorless and harmless air. Is done. In this way, not only is the decomposition and purification of the odor component in the storage container constantly repeated, but also the odor source, which is a source of odor, can be suppressed, thereby sufficiently responding to the generation of new odor in the container. . In addition, when the door is opened for taking out and putting in garbage, the ozone generator is not activated by the switch, suppressing the generation of unnecessary ozone, and the air in the container passes through the deodorizer by operating the suction device. As a result, the air is discharged outside the house as odorless harmless air. Moreover, in this apparatus, the intensity of the odor of the kitchen garbage is detected by the odor sensor, and the ozone concentration and the discharge amount are varied in accordance with the odor sensor to perform an appropriate deodorization process.

[0008]

FIG. 1 shows an embodiment of a kitchen garbage storage measure according to the present invention.
This will be described with reference to FIG.

FIG. 1 is a cross-sectional view of a kitchen garbage storage device according to the present invention. In an upper part of an outer shell 11 storing a resin container 10 having an open upper part, a house outdoor wall 12 and an outer shell 11 are penetrated. Exhaust pipe 1 communicating with the outside of the house and the opening of the container 10
There are three. Similarly, in the upper part of the outer shell 11, a discharge port 15 communicating with the ozone generator 14 is provided in a portion different from the exhaust pipe 13.
Are open toward the opening of the container 10. Exhaust pipe 13
Inside, an ozone decomposing catalyst or both an ozone decomposing catalyst and a deodorizing catalyst are provided from the upstream side with respect to the exhaust stream, and a deodorizer 17 provided with a heater 16 on the outer periphery, and a suction stream is provided downstream of the deodorizer 17. A suction device 18 using a fan is provided.
On the other hand, the container 10 is hung on a fixed claw 21 of a door 20 attached to the base 19 of the sink so as to be openable and closable, and operates integrally with the door 20. Further, the upper part of the door 20 is in contact with a switch 22 provided on the upper part of the outer shell 11. Further, an odor sensor 23 composed of an oxide semiconductor sensor or the like is provided directly above the container 10, and the output is fed back to the ozone generator 14.

On the other hand, in FIG. 2, the switch 22 is interlocked with the ozone generator 14 and the suction device 18, and when the door 20 is open, the ozone generator 14 is stopped and the suction device 18 is operated. Have been.

In the above configuration, when the door 20 is closed, the ozone generator 14 is energized,
The air sucked into the ozone generator 14 from outside the outer shell 11 fills the container 10 from the discharge port 15 as ozone-containing air. At this time, the kitchen wastes present in the container 10 are:
At the same time as being sterilized by ozone and becoming hard to rot,
The odor is also decomposed. In this way, the ozone-containing air used for sterilization and deodorization naturally flows into the exhaust pipe 13 opened directly above the container 10 and passes through the deodorizer 17, whereby the residual ozone is completely decomposed. At the same time, the undecomposed odor is almost completely deodorized and discharged outside as harmless and odorless air. At this time, the odor sensor 23 detects the intensity of the odor of the kitchen garbage, and changes the ozone concentration, the discharge amount, and the like in accordance with the odor to perform appropriate deodorization processing. At the same time, when the ozone concentration is increased, the heater 16 provided in the deodorizer 17 is operated to avoid the outflow of ozone to the outside, thereby promoting the self-decomposition of ozone. Conversely, when the odor is at a low level, the amount of ozone can be minimized, and as a result, power saving can be maintained.

On the other hand, as shown in FIG. 2, the door 20 is opened and the switch 2
2, the ozone generator 14 is stopped, and at the same time, the suction device 18 in the exhaust pipe 13 is operated, whereby the atmosphere in the container 10 is rapidly sucked, and ozone and odor can be prevented from leaking indoors. Therefore, the cleanliness of the kitchen space can be maintained. Further, since the air discharged to the outside is deodorized and harmless air, troubles relating to odor with a neighbor can be avoided.

[0013]

As described above, according to the kitchen waste storage apparatus of the present invention, the following arrangement effects can be obtained. (1) Since the sterilization and prevention of decay of the garbage in the container and the decomposition and purification of the odor can always be changed according to the strength of the odor of the garbage, power saving and efficient deodorization can be performed. (2) Odorless and detoxified air can be exhausted to the outdoors, eliminating environmental problems for other households. (3) When the door is opened, the atmosphere in the container can be prevented from leaking indoors, and the cleanliness of the kitchen space can be maintained.
