PROBLEM TO BE SOLVED: To improve the humidifying efficiency by preventing impurities such as Ca and Mg from being fixed to one position of a humidifying filter, to facilitate the cleaning of the humidifying filter, and to increase the humidifying quantity while minimizing a main body. SOLUTION: In this humidifier, an ultrasonic oscillator 8 is provided on the bottom of an atomization water tank 7, and a cylindrical humidifying filter 9 is rotatably provided above a water level 10 of the atomization water tank 7. Fine water droplets atomized by the ultrasonic oscillator 8 are uniformly supplied to the humidifying filter 9, whereby the humidifying efficiency is enhanced, and impurities such as Ca and Mg are entirely dispersed and adhered to the humidifying filter 9, whereby its local deterioration is prevented. Further, the level 10 of the water tank 7 is raised by attaching an additional nut part 11 to a water supply tank 6, and the ultrasonic oscillator 8 is operated in a state where the lower part of the humidifying filter 9 is submerged, whereby the filter is ultrasonically cleaned. The water tank 7 provided with the ultrasonic oscillator 8 is constituted to be attachable and detachable so that draining is facilitated. COPYRIGHT: (C)2007,JPO&INPIT
