PROBLEM TO BE SOLVED: To provide a mist sauna apparatus which inhibits the proliferation of mold in a bathroom.SOLUTION: The mist sauna apparatus 1 in the bathroom is equipped with air ventilation and heating ventilation circulating features, and a temperature detecting sensor means 10 for detecting a temperature in the bath room, a humidity detecting sensor means 11 for detecting humidity in the bathroom, an attic air temperature detecting means 7 for detecting a temperature of an attic where the mist sauna apparatus 1 is placed, an air flow generating means for generating an air flow on inner surfaces in the bathroom, and an operation control indicating circuit 4 for selecting an operation mode are provided in the mist sauna apparatus 1. The mist sauna apparatus keeps the inside of the bathroom clean and reduces the frequency of the cleaning of the inside of the bathroom by detecting the evaporation of droplets in the bathroom from the air flow generating means from the means 10, means 11, and means 7 and by setting the temperature and humidity to prevent the proliferation of mold.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】換気および暖房換気循環機能を備えた浴室のミストサウナ装置1であって、ミストサウナ装置1内に浴室内の温度を検出する温度検知センサ手段10と、浴室内の湿度を検出する湿度検知センサ手段11と、ミストサウナ装置1が設置してある屋根裏の温度を検知する屋根裏空気温度検知手段7と、浴室の内面に気流を発生させる気流発生手段と、運転モードを選定する運転制御指示回路4とを設け、温度検知センサ手段10と湿度検知センサ手段11と屋根裏空気温度検出手段7から気流発生手段をもとに前記浴室の水滴の蒸発を検知し、カビの繁殖しない温湿度に設定することで、浴室内を清潔に保ち、浴室内の清掃の頻度を低減するミストサウナ装置を得られる。【選択図】図1
