<P>PROBLEM TO BE SOLVED: To control decrease of a humidifying function by accumulation of the decomposed matter in a humidifying liquid tank. <P>SOLUTION: A discharge space S1 which faces a discharge surface 10a is sealed by a cap 40. A humidification pump 53 is driven to rotate forward such that air in a discharge space S1 is humidified while passing through a water tank 54 via an opening 51a and tubes 55 and 56. Humidified air flows into the discharge space via a tube 57 and an opening 51b. When the water in the water tank 54 is determined to start to decompose, the humidification pump 53 is driven to rotate backward such that water stored in the water tank 54 is exhausted through the opening 51a via the tubes 55 and 56. <P>COPYRIGHT: (C)2012,JPO&INPIT |
