Control method and device for air swing of air conditioner and air conditioning system

Abstract

The invention discloses a control method and device for air swing of an air conditioner and an air conditioning system. The control method comprises the following steps of, S1 of acquiring a mode, detecting an operation mode of the air conditioner; and S2 of adjusting, obtaining the target driving voltage value to drive a fan motor at a fixed value when detecting that the air conditioner is started and the swing flap is started or the wind gear is changed in the swing flap, and obtaining the target driving voltage value to drive a fan motor at a fixed value. According to the control method, when a user starts the swing flap or changes the wind gear in the swing flap, through the constant value operation of the fan motor, the load of the fan motor changes along with the change of the position of the swing flap mechanism, and the rotation speed of the motor also changes synchronously; when the load becomes smaller, the rotation speed of the motor is increased, and compared with the driving mode of the fan motor driving voltage change, the wind sound is increased, and the problem that the user experience is poor when the wind sound is large or small due to load change is effectively solved.

Description

Technical field [0001] The invention relates to a household appliance, in particular to a control method, device and air-conditioning system for air-conditioning sweeping. Background technique [0002] In the prior art, the fan motors of wall-mounted air conditioners all adopt PID control methods to detect and control the fan speed in real time. During the sweeping process of the air deflector, the load of the motor will change with the position of the air deflector. When the air deflector is at the maximum and minimum load positions, the control module will control the motor speed to remain unchanged. The same, but because the size of the load changes, the size of the air volume is also changing, causing users to hear the sound of the wind fluctuating, and the experience is very poor. Summary of the invention [0003] The purpose of the present invention is to provide a control method, device and air conditioning system for air-conditioning sweeping to solve the technical proble...

Problems solved by technology

During the sweeping process of the wind deflector, the load of the motor will change with the position of the wind deflector. When the wind deflector is at the maximum load position and the minimum load position, the control module will control the motor speed to remain unchanged. At this time, although the speed Consistent, but because the size of the load changes, the size of the air volume also changes, causing the user to hear the wind sound fluctuating, and the experience is very poor
