PROBLEM TO BE SOLVED: To provide a sauna apparatus wherein dirty water is not stored in a water storage part before starting a sauna operation.SOLUTION: The sauna apparatus includes the water storage part 6 for storing water, a heating means 9 for heating the water in the water storage part 6, a water supply pipe 7 for supplying the water to the water storage part 6, a water supply valve 8 provided in the middle of the water supply pipe 7, a water discharge pipe 12 connected to the bottom part of the water storage part 6 and a water discharge valve 13 provided in the middle of the water discharge pipe 12, and performs the sauna operation of supplying fine droplets and negative ions into a sauna room 2. The sauna apparatus is provided with an operation switch 56 for instructing the operation start and stop of the sauna apparatus and a control means 61 for controlling the sauna apparatus. When the operation start of the sauna apparatus is instructed, the control means 61 opens the water discharge valve 13, then opens the water supply valve 8, supplies the water to the water storage part 6, cleans the water storage part 6, and starts the sauna operation thereafter. Thus, since dirt remaining in the water storage part 6 is surely cleaned and the water is discharged before storing the water in the water storage part 6, clean water can be stored inside the water storage part 6 before starting the sauna operation.COPYRIGHT: (C)2010,JPO&INPIT【課題】サウナ運転開始前に汚れた水が貯水部に貯水されていることのないサウナ装置を提供する。【解決手段】水を貯留する貯水部6と、貯水部6の水を加熱する加熱手段9と、貯水部6に給水する給水管7と、給水管7の途中に設けられた給水弁8と、貯水部6底部に接続された排水管12と、排水管12の途中に設けられた排水弁13とを備え、微細水滴及びマイナスイオンをサウナ室2内に供給するサウナ運転を行うサウナ装置であって、サウナ装置の運転開始及び停止を指示する運転スイッチ56と、サウナ装置を制御する制御手段61とを有し、サウナ装置の運転開始が指示されると、制御手段61は、排水弁13開弁後に給水弁8を開弁し貯水部6に給水し貯水部6を洗浄し、その後にサウナ運転を開始することで、貯水部6に貯水する前に貯水部6に残った汚れを確実に洗浄、排水できるので、サウナ運転開始前には貯水部6内にきれいな水を貯水できるものである。【選択図】 図8
