Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a device for preventing the generation of microorganisms and a method for preventing the generation of microorganisms using the same.

[0002]

2. Description of the Related Art Conventionally, air conditioners (hereinafter,
"Air conditioner"), bathroom, air purifier, washing machine,
Since the temperature and humidity in the kitchen are suitable for the growth of microorganisms such as mold and yeast, for example, mold and yeast easily grow inside the air conditioner, and mold that grows when the power is turned on is It blows out from the air outlet to the room and fills the room. As a result, it may adversely affect your health,
Since it emits a foul odor, it has been a problem in hygiene.

Further, the temperature and humidity are particularly high in the vicinity of the drain hole of the drain pan of the air conditioner, and there is a problem that the drain hole is clogged with slime and mold caused by bacteria.

This causes a problem in the housing structure with high airtightness, but it is also caused by the material and structure of the air conditioner, washing machine, triangular corner of the kitchen, etc.
Humid weather conditions are also involved.

As a method for treating mildew-proofing such as air conditioners, washing machines and triangular corners of kitchens, various anti-mold agents have been used for ABS resin, polypropylene resin, polystyrene resin, etc. forming the air-conditioner itself. For example, a method such as kneading thiabendazole (TBZ), zinc pyrithione, parachlorometaxylenol (PCMX: registered trademark), or coating the resin surface thereof with an antifungal agent or the like is performed.

As another method, a method has been proposed in which a part of the above-mentioned mold-proofed resin is placed in a place where molds easily grow, and the mold-proof treatment is carried out (Japanese Patent Laid-Open No. 63-6330). Issue). However, this method cannot achieve the intended purpose sufficiently because the antifungal agent in the resin has a short lasting effect and is itself deteriorated due to mold and the like.

[0007] Further, a method of spraying a chemical containing a fungicide is widely used on triangular corners and walls of a kitchen where mold is apt to occur. This method
It is easy to use because it is a simple method for the mildew-proofing treatment on places where it is easy to spray or on surfaces such as walls. However, this method has the trouble of spraying while checking the occurrence status inside the air conditioner for air conditioners etc. where molds etc. tend to easily occur under high temperature and high humidity,
Moreover, it has a drawback that the duration of the antifungal effect is short.

[0008] Further, a method of applying an antifungal treatment by applying a coating material containing a chemical such as an antifungal agent is also widely used.

In any case, however, in the use of various antifungal agents and the like, for example, in the vicinity of the drain hole near the drain pan of the air conditioner, an environment in which microorganisms are likely to be generated is always generated from both aspects of temperature and humidity. Therefore, the effects such as mildew proof are not sufficiently exerted. Therefore, in place of the conventional method, there is a demand for the development and practical application of a technique capable of continuously exerting the effects of antifungal and the like by a simple method.
