PROBLEM TO BE SOLVED: To provide a liquid atomizing apparatus capable of more reliably sterilizing the residual water in pipes connecting to a feed water valve.SOLUTION: A liquid atomizing apparatus and sauna room comprise a water reservoir unit that is provided with: a water supply unit 26 as a feed water valve for determining whether water is supplied or not a control unit which controls a primary heat exchanger 11 for performing drying operation to dry the remaining water in the water reservoir unit and a water heat exchanger 15 as a sterilization treatment unit for performing sterilization treatment in the upstream of the water supply unit 26, thus ensuring that the residual water in pipes connecting to the water supply unit 26 can be more reliably sterilized.COPYRIGHT: (C)2015,JPO&INPIT【課題】給水弁と繋がる配管内の残留水をより確実に殺菌することができる液体微細化装置を提供する。【解決手段】貯水部に給水の有無を決定する給水弁としての給水部26と、一次熱交換器11を制御して貯水部の残水を乾燥させる乾燥運転を行う制御部と、乾燥運転時に、前記給水部26よりも上流側で殺菌処理を行う殺菌処理部としての水熱交換器15を備え、給水部26と繋がる配管内の残留水をより確実に殺菌することができる液体微細化装置及びサウナ室を得られる。【選択図】図7
