According to the scheme of the invention, the stepping motor used for driving the swing vanes is controlled according to the acquired swing control instruction, so that the swing vanes can swing according to the swing control instruction; the driving step numbers of the stepping motor during swinging of the swing vanes is recorded, so that the swing position of the swing vanes can be determined according to the driving step numbers; and the swing position can be any position of defined extreme positions of the swing vanes, and thus fully meeting the use requirements of users, and avoiding the defect of the prior art that inconvenience is brought for the users since only fixed air supply can be achieved at preset limited positions.

Description

technical field [0001] The invention relates to the control of household appliances, in particular to a method and device for controlling the swing of an indoor unit of an air conditioner. Background technique [0002] At present, there are generally two ways to control the swing of the indoor unit of the air conditioner: one is manual swing, and the position of the swing is controlled manually; the other is that the stepping motor drives the swing blades of the indoor unit to automatically swing.

Since there are only five swing positions, the number is too small, which has certain limitations, and cannot fully meet the user's requirements for...

AI Technical Summary

Problems solved by technology

Since there are only five swing positions, the number is too small, which has certain limitations and cannot fully meet the user's requirements for any swing position.

[0004] When the user sends a command to stop swinging the wind, the stop position of the swinging blade is not ideal, for example, the deviation in the swinging direction is too large, and the swinging blade can only swing in the opposite direction until it reaches the five fixed positions set. The user's ideal position cannot guarantee timely adjustment of the swing position, which wastes the user's time and energy, and cannot automatically swing the wind within the user's ideal limited area, affecting the user's experience
