Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a living room, office, hotel, hospital, dining room, garbage storage area, automobile, train,
When a bad odor is generated in each room such as a ship, an airplane, and a container for freight due to various causes, the bad odor is deodorized by ozone gas, and cockroaches in each room,
To eliminate rodents and other harmful insects with ozone gas, and also to sterilize bacteria such as bacteria, viruses, molds, etc. adhering to the interior walls and surfaces of objects to automatically obtain a comfortable and healthy living space. For the device.

[0002]

2. Description of the Related Art Conventionally, when deodorizing a bad odor in each room by using this type of device, the air in the room is forcibly sucked into the air passage by the fan of the device and flows, and then flows there. The ozone gas generated by an ozonizer composed of a creeping discharge element is ejected toward the air to deodorize, and then the ozone gas is removed through an ozone killer to form a clean gas and then returned to the room again.

In this case, since only the ozone gas produced by the ozonizer is mixed with malodorous air and brought into contact therewith to cause a deodorizing reaction, the reaction rate is extremely slow peculiar to the gas phase reaction and the deodorizing effect is poor. Further, it is difficult to uniformly mix the Oson gas into the air passage through which a large amount of odorous air in the room passes.Therefore, there is a portion where ozone gas is not mixed and deodorization occurs, and in the discharge generation area of the discharge element that constitutes the ozonizer. Locally generated O, N, NH, NH
₂ , It has a strong deodorizing effect such as OH, etc., but it is returned to the room as it is without being affected by the deodorizing effect of chemically active species with a very short life (collectively referred to as radical below), so it has a high deodorizing effect. Can't expect.

When the ozone gas is mixed and deodorized and then returned to the room again, the ozone gas is always removed by the ozone killer, so that the bad odor of the room air can be deodorized into odorless air. However, it is not possible to kill or sterilize the harmful insects and microorganisms such as bacteria, viruses and molds that live in the room.

That is, the ozone gas is jetted into the air in the air passage inside the apparatus, but since the harmful insects and microorganisms generated in the room cannot be directly contacted with the ozone gas, they are sterilized by insecticide. It is impossible to do.

Further, when the malodorous gas has high humidity or when it is a high concentration of special gas such as hydrogen sulfide, acetone, or aldehyde, it is possible to prevent the occurrence of creeping discharge in the discharge generating area of the creeping discharge element. Or, the wear of the linear electrodes of the surface discharge element becomes severe.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to allow a large amount of malodorous air in a room flowing in the air passage of the present device to pass near the discharge area of a creeping discharge element and to uniformly mix ozone gas generated there. At the same time, the radical generated in the discharge region is made to act on the malodorous substance to decompose it, and a high deodorizing effect can be obtained even in the case of malodorous gas with high humidity or the above-mentioned special gas.

Another object of the present invention is to fumigate the ozone gas directly to the chambers and walls of the room to deodorize it by fumigating the ozone gas and deodorize the ozone, and also to kill and sterilize the harmful insects and microorganisms living in the room. It is to be able to do.

Another object is to make it possible to automatically switch between deodorization and fumigation of air by ozone gas as described above.
