ROTATING ANGEL CONTROL DEVICE OF MOTOR FAN

摘要

A control apparatus of the rotation angle in an electric fan having: a remote controller(18) comprising plural function control buttons and a rotation angle control button(18a) for ordering the rotation angle control mode to remote control a electric fan; a distance sensor(22) mounted on the front part of the electric fan to sense the distance between the electric fan and obstacle; a control part(24) embodying overall control to the electric fan, turning ON a display element(32) mounted to the base(1) of the electric fan in the state which the rotation angle control mode is operated, and controlling the rotation angle of the electric fan according to the distance to the obstacle sensed by the sensor(22); a motor driving part(26) driving a electric motor(28) under the control of the control part(24); and a display control part(30) controlling the turn ON of the element(32) under the control of the control part(24); is disclosed.
