PROBLEM TO BE SOLVED: To provide a liquid refinement device capable of preventing a useless increase in a water storage amount at a water storage part.SOLUTION: A liquid refinement device includes: a fan motor 16 for rotationally driving a fan to suck air into a body case a primary heat exchanger for heating the air sucked by the fan in the body case, and supplying the air as warm air a humidification unit for crushing the water stored in a water storage part into fine water particles based on the operation of a crushing motor 17, humidifying the warm air supplied from the primary heat exchanger by the water particles, and blowing it outside the body case a water supply valve 23 interposed by piping that supplies water to the water storage part and a control part 29 that opens the water supply valve 23 only when the fan motor 16 and the crushing motor 17 are operated.COPYRIGHT: (C)2014,JPO&INPIT【課題】貯水部での貯水量の無用な増大を未然に防止し得る液体微細化装置を提供する。【解決手段】本体ケース内に空気を吸い込むファンを回転駆動するファンモータ16と、ファンで吸い込まれた空気を本体ケース内で温めて温風として送風する一次熱交換器と、破砕モータ17の作動に基づいて、貯水部に貯留された水を細かな水粒に破砕するとともに、該水粒で一次熱交換器から送風される温風を加湿して本体ケース外に送風する加湿ユニットと、貯水部へ水を供給する配管に介在される給水弁23と、ファンモータ16及び破砕モータ17の作動時に限り給水弁23を開く制御部29とを備えた。【選択図】図6
