PURPOSE:To improve a cooling efficiency and to perform energy conservation by providing first control means for reversibly rotating an electric fan when an air conditioner is operated to cool and second control means for forwardly rotating the fan when the conditioner is stopped and a room temperature is a predetermined value or higher. CONSTITUTION:An electric fan 10 is installed in a room 26 having an air conditioner 25. If an operation unit 16 is pressed when the conditioner 25 is operated to cool, an operation switch of the fan 10 is closed, and a set time of a timer is set to match a timer operating time of the conditioner 25. Thus, it is operated as a revere rotation starting type electric fan 10, the cool air of a room 26 is uniformly agitated without blowing the cool air to a user 28, the conditioner 25. When a timer is time's up, the reverse operation is stopped, and the conditioner 25 is also stopped. When the room temperature becomes a predetermined value or more, a temperature sensor detects it, a forward/reverse controller is controlled via a main controller, and a motor 21 is rotated forward. |
