A control method, control device and air conditioner for an air conditioner drainage pump

Abstract

The invention provides a control method and a control device of an air conditioner drainage pump, and an air conditioner, and relates to the technical field of the air conditioners. The control methodof the air conditioner drainage pump comprises the following steps that when the air conditioner is started, a running mode of the air conditioner at last shutdown is acquired, whether the running mode of the air conditioner at last shutdown is a refrigeration or dehumidification mode or not is judged, if not, the drainage pump is controlled not to be started, and a compressor is controlled to run, and if yes, the drainage pump is controlled to be stopped after running t1 duration and then the compressor is controlled to run. According to the control method, the control device of the air conditioner drainage pump and the air conditioner, when the air conditioner is started, the running mode of the air conditioner at last shutdown is judged and the drainage pump is controlled to be startedor not, so that the problems that in the prior art, whether accumulated water exists in a water receiving tray or not, the drainage pump is started and runs a period of time to evacuate the accumulated water, so that the noise is caused and the electricity is wasted are effectively solved, and meanwhile, the service life of the drainage pump can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method, a control device and an air conditioner for an air conditioner drainage pump. Background technique [0002] With the development of air-conditioning technology, the technology of air-conditioning drainage pumps is gradually being updated. [0003] Regardless of the operating mode of the air conditioner when it was turned off last time, the drainage pump in current operation will be turned off after running for a period of time to drain the residual water in the water receiving tray. However, when the last operating mode was heating and other non-refrigerating and non-dehumidifying modes, the drain pump also runs for a period of time and then shuts down. There is no accumulated water in the water tray. The operation of the drain pump not only causes noise, but also affects the operation of the drain pump. service life. [0004] It can be seen that the ...

AI Technical Summary

Problems solved by technology

[0005] The problem solved by the invention is that the existing drainage pump control method is likely to cause noise and affect the service life

[0007] The control method of the air conditioner drainage pump according to the present invention effectively solves the problem of whether there is water accumulation in the water receiving tray in the prior art by judging the operation mode of the air conditioner when the air conditioner was turned off last time and controlling whether the drainage pump is turned on or not when the air conditioner is turned on. , the drainage pump will be turned on for a period of time to empty the noise and power consumption caused by the accumulated water, and at the same time effectively improve the service life of the drainage pump
