Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sleep timer operation method for an electric fan that reduces the rotational speed of a motor and stops the motor after a set time, and is intended to improve the functionality of the electric fan.

Conventionally, in the sleep timer operation method for an electric fan, which reduces the rotation speed of the fan motor and stops the motor after a set time, the motor is rotated at high speed and then at medium speed.

If there are three notches, a strong notch, a medium notch, and a weak notch, which are rotated at low speed, the motor is operated at a strong notch or a medium notch for the first T1 of the sleep timer setting time T, as shown in Figure 1. Thereafter, the motor is operated in a weak notch for the remaining 12 hours and then stopped after the set time T has passed, or the motor is operated in a weak notch for the set time T and then stopped after the set time T has elapsed. At this time, the user must set the sleep timer operation time when sleeping (
All you need to do is select the operating notch of the motor, and while the user is sleeping, the motor's rotation speed will be reduced from the initially set notch speed to the weak notch speed, and after the set time has elapsed, the motor will automatically turn off. will be stopped.

In addition, as shown in FIG. 2, in another conventional fan sleep timer operation method, the motor is operated at a strong notch, a medium notch, or a weak notch for a set time T according to the user's selection. Furthermore, the motor is operated at a low notch for 2I hours.
