Abstract

PURPOSE:To let the user feel comfortable while sleeping by a method wherein after operating a fan for a predetermined period of time, the operation is automatically changed over to the minimum output level and the operation is stopped after a predetermined period of time. CONSTITUTION:When a change-over element 20 of a change-over switch 2 for speed change is connected to a contact 22 to achieve a ''medium'' condition and a knob of a timer is rotated to the maximum extent, a contact (b) is closed and a motor 1 is rotated at a speed corresponding to the ''medium''. After about 1hr and 20min, the contact (b) is opened, while a contact (a) is closed and the motor 1 is rotated at a speed corresponding to ''weakest''. After about 40min., the contact (a) is opened and the motor is stopped, letting the user feel comfortable while sleeping.
