Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing the occurrence of microorganisms and a method for preventing the occurrence of microorganisms using the same.

[0002]

2. Description of the Related Art Conventionally, air conditioners (hereinafter, referred to as air conditioners)
The temperature, humidity, etc. suitable for the growth of microorganisms such as molds and yeasts in bathrooms, air purifiers, washing machines, kitchens, etc. When the power is turned on, mold and the like that are multiplying blow out from the air outlet of the room and fill the room. As a result, it has a bad effect on health and emits a bad smell, which has been regarded as a problem in hygiene. In addition, the temperature and humidity are particularly high in the vicinity of the drain hole of the drain pan of the air conditioner, and there are problems such as clogging of the drain hole by slime and mold caused by bacteria.

[0003] Such a problem has a problem in a house structure having high airtightness, but also has a cause in a material and a structure of an air conditioner, a washing machine, a triangle corner of a kitchen, and the like, and the high temperature and humid weather conditions in Japan. Involved. Such air conditioners, washing machines, treatment methods such as mold prevention of the triangle corner of the kitchen, until now, various mold inhibitor such as ABS resin, polypropylene resin, polystyrene resin and the like forming the air conditioner itself, for example, Thiabendazole (TBZ), zinc pyrithione, parachlorometaxylenol (PCM
X) or the like, or a method of coating the surface of the resin with a fungicide or the like. Further, as another method, a method has been proposed in which a part of the above-mentioned resin subjected to the mildew-proof treatment is placed in a place where molds are easily proliferated, and the mildew-proof treatment is carried out (JP-A-63-6330). . However, this method has a short lasting effect of a fungicide or the like in a resin and is eventually deteriorated by mold or the like, so that the intended purpose cannot be sufficiently achieved.

[0004] In addition, a method of spraying a chemical containing a fungicide or the like is widely used for a triangle corner or a wall of a kitchen where mold is easily generated. This method is easy to use since it is a simple method for treating the surface of a wall or the like where mold is easily sprayed. However, this method has the trouble of spraying while checking the condition of the inside of the air conditioner for air conditioners and the like, which are liable to generate mold at high temperature and high humidity. Has a shortcoming of a short duration.
Also, a method of applying a paint containing a chemical such as a fungicide to perform a fungicide treatment has been widely performed.

However, in any case, in the conventional methods of using various antifungal agents, for example, the vicinity of the drain hole near the drain pan of an air conditioner is in an environment where microorganisms are always liable to be generated in terms of both temperature and humidity. Therefore, sufficient effects such as mold prevention are not exhibited. Therefore, there has been a demand for the development and commercialization of a technique that can easily exhibit the effect of preventing mold and the like in a simple manner instead of the conventional method.
