BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can effectively eliminate harmful small insects floating in the indoor air of buildings, aircraft, ships, etc. in a very short time, and can also be used in hospitals, hotels, etc. The present invention relates to a method for eradicating harmful small insects in indoor air that can be insecticidally treated even if there is an obstacle.

[0002]

2. Description of the Related Art Conventionally, harmful small insects such as mites are suspended in the interiors of buildings, airplanes, ships, etc., and therefore insecticides have been carried out by chemicals in order to maintain good hygiene in these interiors. . However, the conventional insecticidal method mainly aimed at exterminating harmful small insects is to atomize the drug solution with a power sprayer or a human power sprayer and spray it into the room, so that it is sprayed uniformly throughout the room. It is difficult to get rid of insects such as shadows and pits, and in buildings with a large number of rooms, there is a problem that it takes a lot of time and labor to kill insects. Since many of them are very strong, there is a risk that the workers will be contaminated with the chemicals and may endanger their health. Not only that, but this method also has the problem that the chemical drops as drops of water on the floor, discoloring the P tiles, baking the carpet, etc. In the case of a computer room, the chemicals become drops of water and the computer However, this method had a problem that the computer room could not be disinfected because it would cause computer failure.

Heretofore, insecticidal treatment with a substance that does not cause water droplets to fall has not been carried out so much. Even if the room is insecticidally processed, since many harmful small insects are propagated in the air conditioner and they enter the room, the insecticidal effect is not so high. Furthermore, in the insecticidal treatment in a room where people are always present, such as in a hospital or a hotel, since the drug used for the insecticide is highly toxic to the human body,
The reality is that it is not done at all. Especially, in the indoor air of a building or the like, mites are mixed with dust and float, and there are problems that the mites are stung by the mites and the skin is swollen red, and the mites cause diseases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and can effectively kill harmful small insects floating in the indoor air of buildings, airplanes, ships, and the like. In addition to being able to do it, you can perform insecticidal work in a room with people such as hotels and hospitals without any trouble,
An object of the present invention is to provide an insecticidal method in which the room is not polluted much even after the insecticidal treatment.

[0005]

Means for Solving the Problems As a result of earnest research for achieving the above-mentioned object, the present inventor has found that small insects floating in the air have the property of moving with the air, and that building, aircraft, ships, etc. Focusing on the fact that an air conditioner is installed in the room, we thought about using this air conditioner to eradicate small insects in the air, let the air filter of the air conditioner hold the insecticide, and By passing this through the air filter, small insects in the indoor air can be eradicated in an extremely short time and effectively, and the small insects in the air conditioner are also killed at the same time. The present invention has been achieved by discovering that it is unlikely to be contaminated with.
That is, the present invention is characterized in that the air filter of the air conditioner holds the insecticide, the air conditioner is operated, and the air in the room passes through the air filter.

As the insecticide used in the present invention, a liquid or solid insecticide at room temperature can be selected and used according to the kind of small insects to be eradicated. At this time, if a drug having an insecticidal action and a bactericidal action, such as hydrogen peroxide water, is used, eradication of small insects in the air and sterilization of indoor air can be achieved at the same time.

In order to hold the insecticide in the air filter of the air conditioner, the liquid insecticide may be held directly in the air filter, or the liquid insecticide may be held in a suitable air filter medium, and the liquid insecticide is held in the air filter. You may fix it. Examples of the air filter medium include fibrous activated carbon, cloth, glass fiber,
Asbestos fibers and the like can be used. When a solid insecticide is used, it is advisable to mix the air filter medium with the insecticide. In addition, if the air filter medium is made to have a sterilizing property such as containing a solid sterilizing substance, sterilization of indoor air can be achieved at the same time as insecticide. The type of air conditioner used in the present invention is not particularly limited, but in the case of a central type air conditioner, the effect of the present invention is particularly exerted. This is because a central air conditioner can simultaneously disinfect many rooms at the same time.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the insecticidal method of the present invention will be further described with reference to the drawings. The figure is a schematic diagram when a central type air conditioner is used. When the outside air is introduced into the air conditioner 1, the outside air passes through the air preheater or the air precooler 2, the air filter 3, the air cooler 4, the air heater 5, and the scavenging humidifier 13, and the blower 6 Air is introduced into the room 7 from the air outlet 8. The introduced air can be exhausted from the return 9, or the return 9 can be closed and sucked from the air outlet 8 to circulate between the air conditioner and the room, or can be exhausted as it is. In the figure, 10 is a room thermostat, 11 is a cold water pump, and 12 is a hot water pump.

The air filter 3 contains 3 as a germicide.
A glass fiber nonwoven fabric 15 impregnated with a% hydrogen peroxide solution is fixed. Using the device configured as above,
8 built-in 120 rooms, total room area 8000m ² inside the building, return air from the room 9 into the air conditioner 1 and the space between the room 7 and the air conditioner 1 in 7 to 10 minutes. One cycle was performed and the air conditioner was operated for 2 hours. The glass fiber nonwoven fabric 15 was sprayed with a 3% hydrogen peroxide solution every 20 minutes. As a result of the above experiment, it was confirmed that 70% of mites were eradicated in the room 7 and the air conditioner 1. In addition, since the duct inside the air conditioner also sucks the air above the ceiling of the building and the air behind the ceiling also passes through the air filter, the air behind the ceiling also circulates and passes through the air filter.
The air behind the ceiling is also killed at the same time. Due to the insecticidal treatment, many humans in the room were often stung by ticks before the treatment, whereas no humans were bitten by the ticks after the treatment.

The liquid insecticide may be directly sprayed by a sprayer, but may be sprayed automatically or, depending on the position of the humidifier 13, sprayed from the humidifier. You can also If the liquid insecticide having a low volatility is used, once the insecticide is held directly in the air filter or through the filter medium, it is not necessary to further spray the insecticide. In the figure, 16 is a control valve for sending cold air from the refrigerator to the air cooler 4, and 17 is a control valve for sending hot air from the boiler to the air heater 5, which is controlled by a computer. It is designed to open and close automatically. The method of the present invention is not limited to buildings, ships and aircraft,
It can also be applied to the elimination of small insects floating in the air of vehicles such as trains. In short, any room may be used as long as the air of the air conditioner circulates.

[0011]

[Effect] As described above, according to the present invention, a normal air filter for an air conditioner is used, and a pesticide is held in the air filter to eliminate harmful small insects in the air in the room. Since it is possible to effectively kill insects in every corner of the room at the same time regardless of the number of rooms, it is possible to significantly reduce the cost of killing harmful small insects in the indoor air. Since it is possible to eliminate harmful small insects in the air in the air conditioner and in the attic, which has never been treated by insecticide, it is possible to prevent recontamination of the room by harmful small insects in the air conditioner. It has a tremendous effect not seen in the conventional insecticidal method of this kind at all, such that it can reduce the number of harmful small insects. Further, according to the method of the present invention, since it is possible to make a state in which almost no insecticide is present in the room, it is possible to perform insecticidal treatment without any trouble even when there are people in the room, especially in hospitals, hotels, etc. It is effective in eradicating small insects in the air.
