PURPOSE:To clean adhering of dusts at a humidifying plate, improve it in view of performance as well as sanitation and elongate a life of a humidifying device by a method wherein even after an air supplying blower is stopped, a water feeding for a humidifying device is continued for a predetermined period of time. CONSTITUTION:During a heating operation, a water supplying blower 113 is operated, air passed through a heat exchanger 107 flows through an air supplying passage 111. The air passes through a gasification humidifying device 117 and is humidified. Then, water supplying satisfactory for a normal humidification is carried out through an electric valve 18 disposed in a water supplying pipe 118a. After the air supplying blower 113 is stopped, an opening of the electric valve 118 is made large for a specified period of time set by a timer 120. A large amount of water is flowed in a gasification type humidifier 117 to clean it and then the electric valve 118 is also stopped. In this way, after the air supplying blower is stopped, the humidifying plate is hardly clogged due to the blown air as well as supplied water fed to the gasification humidifying device and further no nutriuous substance is found and occurrence of mold can be prohibited. |
