PROBLEM TO BE SOLVED: To provide a sauna apparatus in which hot air having a temperature not largely deviated from a set temperature can be supplied into a sauna room.SOLUTION: In a stable mode in which sauna bathing is possible, a value detected by a room temperature sensor 52 for sensing the temperature in the sauna room 2 is compared with the set temperature, and a value detected by a reserved water temperature sensor 50 for sensing the temperature of hot water in a water reservoir 6 is compared with the set temperature. Then, if the values are equal to or lower than the set temperature, a heater 9 in the water reservoir 6 is turned ON, and if they are higher, the heater 9 is turned OFF. With this configuration, since the temperature of hot water in the water reservoir 6 can shift around the set temperature, hot air having a temperature largely deviated from the set temperature is not supplied into the sauna room 2, and thus, an increase in the number of times of turning ON-OFF of the heater 9 can be prevented.COPYRIGHT: (C)2012,JPO&INPIT【課題】 設定温度から大幅に外れることがない温風をサウナ室内に供給可能なサウナ装置を提供する。【解決手段】 サウナ入浴が可能な安定モード時において、サウナ室2内の温度を検知する室内温度センサ52で検知された値と設定温度とを比較し、また、貯水部6内の温水温度を検知する貯水温度センサ50で検知された値と設定温度とを比較して、設定温度よりも所定値以下の値であれば貯水部6内にある加熱ヒータ9をONし、設定温度よりも所定値以上の値であれば加熱ヒータ9をOFFすることで、貯水部6内の温水温度を設定温度付近で推移させることが可能となるので、サウナ室2内に設定温度から大幅に外れた温度の温風が供給されず、加熱ヒータ9のON/OFF回数が増加することを防止できる。【選択図】 図9
