HUMIDIFIER

PROBLEM TO BE SOLVED: To provide a humidifier capable of detecting a no-water heating state in a water storage chamber instantaneously.SOLUTION: A humidifier includes: a blower fan 14 installed on a further upstream side than a water storage chamber 8, and blowing humidification air generated in humidification air generation means 10, 12, 13 to indoors from an air blowing port 2 with indoor air sucked from a suction port 17; an air blowing passage 15 connected on a further downstream side than the water storage chamber 8, and guiding the humidification air blown by the blower fan 14 to the air blowing port 2; and control means for controlling drive of the humidification air generation means 10, 12, 13 and the blower fan 14. The humidifier performs humidification indoors. The water storage chamber 8 includes a temperature thermistor 21 for detecting the temperature of the water heated in a heating heater 18, and by calculating a temperature gradient of the temperature thermistor 21 before and after a certain time, presence/absence of water or the amount of water in the water storage chamber 8 are detected, and heating of the heating heater 18 is stopped.SELECTED DRAWING: Figure 2 【課題】貯水室の空焚き状態を瞬時に検知することができる加湿装置を提供する。【解決手段】貯水室８より上流側に設置され吸い込み口１７から吸い込んだ室内空気で、加湿空気発生手段１０,１２,１３で発生した加湿空気を送風口２から室内へ送風する送風ファン１４と、貯水室８より下流側で接続し送風ファン１４により送風された加湿空気を送風口２まで案内する送風通路１５と、加湿空気発生手段１０,１２,１３及び送風ファン１４の駆動を制御する制御手段とを備え、室内の加湿を行うようにしたもので、貯水室８には加熱ヒータ１８で加温される水の温度を検知する温度サーミスタ２１を備え、この温度サーミスタ２１の一定時間前後の温度勾配を算出することで、貯水室８内の水の有無或いは水の量を検知して、加熱ヒータ１８の加熱を停止する。【選択図】図２
