Abstract
PURPOSE: To enable to stop and start operation of an electric fan automatically in response to the output of an ultrasonic sensor which is capable of detecting motion of a human body.
CONSTITUTION: An electric fan 1 of this invention is provided with a transmitter 7A which emits ultrasonic waves, a receiver 7B constituting an ultrasonic sensor for receiving the reflection waves, and control means 8 which is operated in response to the signal received by the receiver 7B when a human body is detected within an oscillation range 10 of the electric fan. With such as arrangement, the electric fan is set into operation for producing artificial draft of cool air only when a human body exists within the oscillation range of the fan, but operation of a driving motor is stopped when he leaves the range.
