PURPOSE:To prevent moisture condensation water from dropping into a bathroom from a louver so as not to give an uncomfortable feeling to a bather by a method wherein the title exhaust fan is equipped with a louver which covers an air suction port of a frame body from the inner side of a room and a vaporizer which is provided at a water collecting part in which moisture condensation water generated in the frame body is collected. CONSTITUTION:When a blade 6 is rotated by operating a motor 5, air in a bathroom is sucked into a suction port 3 from a louver 99 as shown by white arrow and is exhausted outside of the room from a discharge port 7 through an exhaust duct by the blade 6. At this time, as the passing air has high humidity, the moisture is condensed on the inner wall of a frame body 1. The moisture condensation water flows down along the inner wall of the frame body 1 as shown by black arrow, reaches the louver 9, and runs on the rear surface of the louver 9 to the center because of the tilt, and collected in a water collecting part 9a. The collected moisture condensation water is vaporized by a vaporizer 11 and is exhausted outside of the room from the discharge port 7 through the exhaust duct, together with sucked air from the bathroom. Thus, the moisture condensation water is vaporized by the vaporizer 11 and is exhausted outside of the room and does not drop into the bathroom, and therefore, the moisture condensation water does not give an uncomfortable feeling by hitting a bather. |
