【０００２】[0002]
【発明の技術的背景】近年、病院等における院内感染
（ＭＲＳＡ）やウィルス汚染防止の観点から屋内殺菌の
重要性が強く指摘されている。BACKGROUND OF THE INVENTION In recent years, the importance of indoor sterilization has been strongly pointed out from the viewpoint of preventing nosocomial infection (MRSA) and virus contamination in hospitals and the like.

問題がある。2. Description of the Related Art Conventionally, for sterilizing indoors such as hospital rooms, a method using ozone or a method using a mop or the like using sodium hypochlorite or another disinfectant is known. However, ozone is decomposed and the bactericidal effect is lost at an early stage, and the disinfectant has the following problems due to phytotoxicity and other reasons.

であることに起因している。Heretofore, indoor disinfection using a disinfectant has mainly been performed by wiping with a mop, and disinfection by spraying the disinfectant indoors has been erroneously performed. The reason is that indoor spraying of chemicals such as disinfectants can cause a large amount of chemicals to be inhaled by the sterilization worker, cause the chemicals to be exposed to the eyes and skin, and the sterilization effect is uncertain compared to the wiping method. It is due to being.

l), which causes a chlorination reaction or an oxygenation reaction to exert a bactericidal action. In order to obtain an effective bactericidal effect, the concentration of the aqueous sodium hypochlorite solution is set to a high concentration. There is a need. However, when the concentration is high, a high concentration of the drug remains, causing the above-mentioned chemical damage.

いう不都合があった。[0006] Further, even if a disinfectant such as an aqueous solution of sodium hypochlorite is sprayed to sterilize, the spray increases the indoor humidity to 100% or more, and the disinfectant drops as water droplets from ceilings and walls. No bactericidal effect is obtained without spraying. For this reason, there is a disadvantage that the work cannot be performed when there is a person or where there is a material that must be sterilized such as a futon.
