PROBLEM TO BE SOLVED: To provide a mist generator capable of preventing freezing of water stored in a water storage room and ensuring driving a drive motor.SOLUTION: If an operation switch 42 is operated, a temperature sensor 23 detects a temperature of water stored in a water storage chamber 8. If the detected temperature is lower than 0°C, then it is determined that the water in the water storage room 8 is frozen, driving of a drive motor 13 is stopped, and a heating heater 22 is turned on to heat the water in the water storage room 8. If the temperature detected by the temperature sensor 23 is equal to or higher than 0°C, then it is determined that the water in the water storage room 8 is defrosted, the heating heater 22 is turned off, and the driving of the drive motor 13 is started. By doing so, even if there is a possibility that a surrounding temperature of a device main body 1 is low and that the water in the water storage room 8 is frozen, the driving of the drive motor 13 is started after the water surrounding a drive shaft 18 is defrosted. It is, therefore, possible to ensure supplying nano mist and negative ions into a room and to prevent failure of the drive motor 13.COPYRIGHT: (C)2014,JPO&INPIT【課題】 貯水室内の貯水の凍結を防止して駆動モータを確実に駆動させるミスト発生装置を提供する。【解決手段】 運転スイッチ42が操作されたら温度センサ23で貯水室8内の水の温度を検知し、検知された温度が0℃未満であれば貯水室8内の水が凍結しているとして、駆動モータ13の駆動を停止させて加熱ヒータ22をONにして貯水室8内の水を加熱し、温度センサ23で検知された温度が0℃以上となったら、貯水室8内の水は解氷したとして加熱ヒータ22をOFFにして駆動モータ13の駆動を開始することで、器具本体1の周囲の温度が低く貯水室8内の水が凍結する虞があっても、駆動軸18の周囲にある水を解氷してから駆動モータ13の駆動を開始するので、確実に室内へナノミストと負イオンを供給可能であり、駆動モータ13の故障を防止できる。【選択図】 図4
