PURPOSE:To shorten a rising time at the time of a humidifying temperature and to greatly improve humidifying capacity by providing a water receiving tray in a heater duct, diffusing water stored in the tray and the air from a heat generator to a filter which absorbs water to be passed by switching a damper, and vaporizing moisture. CONSTITUTION:When an operation is started, a fan 4 is rotated, the air in a room is sucked from a suction port 2, guided from the discharge side of a spiral casing 7 to a heater duct 10, and passed through a heat generator 8 to be heated. A ventilation passage is formed at an upper or lower side by switching the passage of a damper 11. When the damper is here operated to pass the passage of the lower side, the heated air is brought into contact with the surface of water pool 16 such as a drip pan 15, etc., provided in the duct 10, further passed through a water absorption filter 18 attached to the damper, and diffused from a warm air diffuser 9 into the room as humidified warm air. When the damper is operated to pass the passage of the upper side, the air is diffused from the diffuser 9 into the room as the warm air. |
