PROBLEM TO BE SOLVED: To provide a liquid atomizing device and a sauna apparatus using the same which are simplified in construction by eliminating piping for discharging a liquid not atomized.SOLUTION: A liquid atomizing device includes: a heat exchanger 7 and a fan motor 8 provided in a blow passage connecting a suction port 4 and an exhaust port 5 liquid atomizing means 9 arranged between the fan motor 8 and the exhaust port 5 and control means for controlling the liquid atomizing means, the heat exchanger 7, and the fan motor 8. The rotating means 13 of the liquid atomizing means 9 includes: a rotation shaft 19 and an inverted cone shape water-lifting tube 22 formed in the axial direction of the rotation shaft 19 by integration with multiple rotating plates 20a, 20b, and 20c turned about the rotation shaft 19. The control means includes a control part for controlling water supply to the rotating means 13 and the operations of the rotating means 13, the heat exchanger 7, and the fan motor 8. The control part performs a drying operation to dry water left in a water storage part when liquid supply is stopped.COPYRIGHT: (C)2012,JPO&INPIT【課題】本発明は、液体微細化装置とそれを用いたサウナ装置に関するもので、微細化できなかった液体の排出のための配管施工を解消し、施工工事を簡単にすることを目的とする。【解決手段】吸込口4と排気口5を結ぶ風路に設けた熱交換器7およびファンモータ8と、このファンモータ8と排気口5間に設けた液体微細化手段9と、この液体微細化手段と熱交換器7およびファンモータ8を制御する制御手段を備え、液体微細化手段9の回転手段13は、回転軸19と、この回転軸19の軸方向に、回転軸19を中心として回動する複数の回転板20a,20b、20cと一体に形成された、逆円錐状の揚水管22を備え、前記制御手段は、回転手段13への水供給と回転手段13と熱交換器7およびファンモータ8の運転とを制御する制御部を備え、この制御部は、液体供給停止時に、前記貯水部の残水を乾燥させる乾燥運転を行う。【選択図】図5
