PROBLEM TO BE SOLVED: To provide an indoor sterilization method capable of simultaneously sterilizing not only a ceiling and walls but also the air by atomization without a chemical injury and obtaining a sufficient sterilization effect by humidity not generating waterdrops. SOLUTION: Sterilization water containing hypochlorite water of pH 3-7.5 and hypochlorous acid conc. 10-200 ppm is turned to the mist-like water particles of 0.5 μm-50 μm and atomized indoors from an upper discharge port 15. Preferably, the sterilization water is micronized to the mist-like water particles of 0.2 μm-5 μm and discharged. Further preferably, the sterilization water is atomized only to a super fine mist of less than 0.3 μm and atomized. By sucking the hypochlorite sterilization water to the jet steam of high temperature steam and jetting it, it can be turned to the mist-like water particles of about 80 deg.C mainly of 0.5 μm-50 μm. The mist-like water particles of the hypochlorite sterilization water can be atomized while imparting electric charges. Preferably, the indoor humidity during the atomization is suppressed below 90% and the atomization is performed indoors. |
