Abstract
The present invention relates to a method for controlling the operation of an electric fan. The primary objective of the present invention is to automatically adjust the requirement of the blowing of the fan in sleeping time at night. Therefore, in a sleeping status at night, the invented electric fan is designed by that a small operating cycle of the fan is gradually changed from blowing for a long period of time and stopping operating for a short period of time to blowing for a shortened short period of time and stopping operating for a lengthened period of time, operating for a fixed period of time prior to stopping operating for a changeable period of time which extends by the extension of the sleeping time, or operating for a long period of time which shortens due to the extension of the sleeping time prior to stopping operating for a fixed period of time. In this way, the automatic adjustment can reduce the requirement of the blowing of the fan, so the sleeping user will not catch cold so easily as caused by the conventional electric fans. The present invention controls the operation of the electric fans by embedding software in a microprocessor or by using an application specific integrated circuit.
