Problems solved by technology

[0006] However, for option 1, the user's selection range is simply increased to 6 gears. Although the optional range has increased, it has not fully utilized the stepless speed regulation function of the DC motor.
Although Option 2 is a stepless speed regulation solution, the user can freely choo

Abstract

The invention provides a control method and device of a DC fan, an air conditioner and a controller of the air conditioner. The control method of the DC fan comprises the steps of receiving a self-defined instruction of a user to the rotating speed of the fan; determining the rotating speed percentage set by the user for each fan tap position of the DC fan according to the self-defined instruction; and storing the multiple fan tap positions of the DC fan and the rotating speed percentages corresponding to the fan tap positions. Through the technical scheme, it can be guaranteed that the user can regulate the rotating speed of the DC fan flexibly, and the operating difficulty of regulating the rotating speed of the DC fan every time by the user can be reduced.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method for a DC fan, a control device for a DC fan, an air conditioner and a controller for the air conditioner. Background technique [0002] In traditional air-conditioning applications, the indoor fan of the air conditioner mainly uses an AC motor. Although the manufacturer provides 3 or 4 speeds for users to choose, since the AC motor uses different distribution of windings to achieve adjustable speed, each The motor speed corresponding to the gear is constant, and the user can only choose one of the gears to use, and can no longer freely adjust the speed of the indoor fan according to the actual use environment and personal subjective feelings. [0003] At present, DC motor technology is used more and more in air-conditioning equipment. The DC fan realizes adjustable speed and can achieve stepless speed regulation, so that users can freely set the ...
