PROBLEM TO BE SOLVED: To provide a sauna apparatus used for making a bathroom into a sauna space which dispenses with a humidity sensor and warms the bathroom comfortably without being affected by cold radiation from floor or walls of the bathroom.SOLUTION: The sauna apparatus comprises a warm air blowing means 5a for blowing air warmed by a warming means 3 into the bathroom, a humidified air blowing means 5b for blowing air humidified by a humidifying means 4 into the bathroom, a bathroom temperature detection means 9 for detecting the temperature within the bathroom, an outside temperature detection means 10 for detecting the temperature outside of the bathroom, and a means for detecting the temperature of excess humidifying water 11 for detecting the temperature of humidifying water not used by the humidifying means 4. The sauna apparatus adjusts the degree of warming and humidification on the basis of the temperatures detected by the bathroom temperature detection means 9, the outside temperature detection means 10, and the means for detecting the temperature of excess humidifying water 11. With such a configuration, the sauna apparatus dispenses with a humidity sensor and controls to keep comfortable temperature and humidity while preventing cold radiation.COPYRIGHT: (C)2007,JPO&INPIT【課題】浴室内をサウナ空間とするサウナ装置において、湿度センサを使用せず、浴室の床や壁面からの冷輻射の影響を防止し、快適な状態とすべく温度、湿度が制御されるサウナ装置を提供することを目的としている。【解決手段】空気を加温手段3により加温した空気を浴室内に送風する加温空気送風手段5aと、加湿手段4により加湿た空気を浴室内に送風する加湿空気送風手段5bと、浴室内の温度を検出する浴室内温度検出手段9と、浴室外の温度を検出する機体外温度検出手段10と、加湿手段4が加湿に使用しなかった加湿水の温度を検出する余剰加湿水温度検出手段11を備え、浴室内温度検出手段9、機体外温度検出手段10、余剰加湿水温度検出手段11が検出した温度に基づいて加温および加湿量を調整することで、湿度センサを使用せず、冷輻射を防止して、快適な温度、湿度に制御されるサウナ装置を提供できる。【選択図】図1
