PROBLEM TO BE SOLVED: To provide a compact sauna apparatus which is free of corrosion or leakage.SOLUTION: The sauna apparatus includes water crushing means 23 which pumps up hot water stored in a water storage section 6 by rotation of a rotary body 25 and throwing the hot water toward a porous body 30 to crush the hot water and to generate fine droplets and negative ions, a blower 36 which supplies the fine droplets and negative ions generated by the water crushing means 23 to a sauna room 2, and air heating means for heating the air circulated by the blower 36 within the sauna room 2. The sauna apparatus carries out sauna operation by supplying the fine droplets and the negative ion to the sauna room 2. The blower 36 is arranged between the water crushing means 23 and a water outlet 5, and a collecting groove 41 is arranged on the inner bottom of a casing 39 covering the blower 36 so as to collect dew condensation and to discharge the dew condensation from a communicating port 43 opening to the collecting groove 41. With such a configuration, corrosion and leakage are credibly prevented and the apparatus can be used safely for a long time.COPYRIGHT: (C)2011,JPO&INPIT【課題】コンパクトでありながら腐蝕や漏れの心配がないサウナ装置を提供する。【解決手段】貯水部6に貯留された温水を前記回転体25の回転により汲み上げ前記多孔体30にぶつけて破砕して微細水滴及びマイナスイオンを生成する水破砕手段23と、該水破砕手段23で生成された微細水滴及びマイナスイオンをサウナ室2内に供給する送風機36と、該送風機36によって循環されるサウナ室2内の空気を加熱する空気加熱手段とを備え、前記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、前記送風機36を水破砕手段23と放出口5との間に設け、該送風機36を覆うケーシング39の内壁底部には捕集溝41を設けて結露水を捕集し、該捕集溝41に開口する連通口43から排水するようにしたので、腐蝕や漏れを確実に防止して、長期に渡って安心して使用出来るものである。【選択図】図2
