PROBLEM TO BE SOLVED: To provide a mist sauna apparatus for suppressing propagation of molds in a bathroom.SOLUTION: Mist jet operation into the bathroom is performed by an operation control instruction circuit 4 as operation control means and hot water at a temperature of 40 to 60°C is heated and vaporized steam is sent into the bathroom by a fan 108, so that air on the wall surface in the bathroom and in the bathroom is kept at a temperature of 40 to 50°C and a humidity of 99 to 100%RH in which molds do not generate and temperature on the wall surface in the bathroom is kept at a temperature of 40 to 50°C of the temperature in which the molds do not generate. Thus, in the mist sauna apparatus, propagation of molds can be suppressed.COPYRIGHT: (C)2009,JPO&INPIT【課題】浴室内のカビの繁殖を抑制するミストサウナ装置を提供することを目的とする。【解決手段】運転制御手段としての運転制御指示回路4により、浴室内にミスト噴霧運転を行い、40℃~60℃の温水を加熱し気化した水蒸気を送風機108により浴室内に送ることで、浴室内壁面および浴室内の空気をカビの発生しない温湿度の40℃以上50℃以下、99%RH以上100%RH以下に、浴室内壁面温度をカビの発生しない浴室内壁面温度の40℃以上50℃以下にすることにより、カビの繁殖を抑制するミストサウナ装置が得られる。【選択図】図1
