s102, detecting a vertical distance between the fan assembly and a preset position where the fixing frame is located;

and S103, controlling the fan assembly to rotate at a preset speed according to the detected vertical distance.

In specific implementation, the height between the fan assembly and the ceiling can be divided into a first-level distance, a second-level distance and a third-level distance, and when the vertical distance detected by the controller is the first-level distance, the controller controls the fan assembly to rotate at a first initial preset rotating speed N1 so as to blow out a first preset air volume; when the vertical distance detected by the controller is the secondary distance, the controller controls the fan assembly to rotate at a second initial preset rotating speed N2, so that a second preset air quantity is blown out; when the vertical distance detected by the controller is the three-level distance, the controller controls the fan assembly to rotate at a third initial preset rotation speed N3, so that a third preset air volume is blown out.

Wherein, when fan unit risees to predetermineeing the height, be used for also can increasing, reducing the rotational speed of fan in the control interface of controller according to the in-service use requirement to change the default rotational speed of predetermineeing, thereby make fan unit rotate with user-defined rotational speed in order to obtain more comfortable amount of wind, the flexibility is good, and air regulation scope is big, and the suitability is good.

It can be understood that step S101 and step S102 are not in sequence, that is, when the specific implementation is performed, step S101 may be performed first, and the vertical distance between the fan assembly and the preset position where the fixing frame is located is adjusted, that is, the fan assembly is lifted to the preset position and then step S102 is performed; of course, step S102 may be executed first, so that the fan assembly rotates to blow out the air volume first, and then step S101 is executed to lift the fan assembly to the preset position, which may be arbitrarily selected according to the specific use environment, and is not limited herein.
