Summary:PURPOSE:To make it possible to carry out ventilation within a room of a housing in which ventilation fans cannot be fixed to the wall surface within the room. CONSTITUTION:A fan 5 is provided on the ceiling surface within the room, and further a fan 6 is provided on the outer air surface in the ceiling 8. The fans 5 and 6 have a substantially equal air quantity. Upon ventilating a room provided with the fan, when a fan driving switch 7 is turned ON, the fans 5 and 6 are driven at the same time, and air in the room is discharged by the fan 5 into the ceiling 3. Then, the air is discharged out of the room from the ceiling and the ventilation is thus performed. By this procedure, the duct resistance is extremely small and the capacity of the fan becomes extremely miniaturized.
