Air conditioner and control method thereof

Abstract

The invention belongs to the technical field of air conditioners, and particularly provides an air conditioner and a control method thereof. The control method of the air conditioner comprises the following steps of: detecting a first air outlet speed at an air outlet of the indoor unit; comparing the first air outlet speed with a preset reference air speed and judging whether to enter a first self-cleaning stage according to the comparison result; detecting a first air outlet temperature at the air outlet after the first self-cleaning stage is finished; comparing the first air outlet temperature and a preset temperature and judging whether to enter a second self-cleaning stage according to the comparison result. By using the control method, whether to enter the second self-cleaning stageis determined according to the air outlet temperature after the first self-cleaning stage is finished, the situation of energy waste caused by incomplete cleaning of the first self-cleaning stage andcontinuously carrying out two self-cleaning stages is avoided, and the problem that the energy waste caused by incomplete cleaning or excessive cleaning is easy to occur in the self-cleaning control method of a prior air conditioner is solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. Background technique [0002] When the indoor unit of the air conditioner is running in the cooling or heating mode, the air in the indoor environment enters the interior of the indoor unit from the air inlet of the indoor unit for heat exchange, and is discharged from the air outlet. During this process, the dust and large particles mixed in the indoor air will enter the interior of the indoor unit with the air and adhere to the surface of the filter and heat exchanger, directly affecting the heat exchange between the heat exchanger and the indoor air. , and affect the air quality. In order to ensure heat exchange efficiency and air quality, the indoor unit needs to be cleaned regularly. The traditional cleaning method is manual cleaning, which is time-consuming and laborious, and the user experience is poor. ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the self-cleaning control method of the existing air conditioner is prone to the problem of incomplete cleaning or excessive cleaning resulting in energy waste, on the one hand, the present invention provides a control method for the air conditioner, The air conditioner includes an indoor unit, and the control method includes the following steps: detecting a first air outlet speed at an air outlet of the indoor unit; comparing the first air outlet speed with a preset reference wind speed and according to the comparison result Judging whether to enter the first self-cleaning stage; detecting the first air outlet temperature at the air outlet after the first self-cleaning stage is completed; comparing the first air outlet temperature with a preset temperature and judging whether to Enter the second self-cleaning stage
