Embodiment
[0055] The embodiment of the present invention provides a self-cleaning control method. The self-cleaning control method provided by the embodiment of the present invention is mainly used in air conditioners to clean the outdoor heat exchanger of the air conditioner. The self-cleaning control method provided by the embodiment of the present invention The control method can accelerate the frosting of the outdoor heat exchanger after responding to the cleaning instruction, and increase the frosting speed of the outdoor heat exchanger, thereby improving the cleaning effect.
[0056] With the improvement of living standards and technological levels, people have higher and higher requirements for the comfort of air conditioners. Generally, the outdoor unit of the air conditioner is installed outdoors. After the air conditioner has been running for a period of time, the heat exchanger of the outdoor unit will be covered with some impurities, which will affect the heat transfer perfor...

The invention provides a self-cleaning control method and device and an air conditioner, and relates to the technical field of air conditioners. The self-cleaning control method comprises the steps that a cleaning instruction is responded, and an outdoor coil pipe temperature value of an outdoor heat exchanger and an indoor coil pipe temperature value of an indoor heat exchanger of the air conditioner are obtained; the operation state of the air conditioner is adjusted according to the indoor coil pipe temperature value and the outdoor coil pipe temperature value, so that an outdoor heat exchanger is quickly frosted; and the air conditioner is controlled to enter a defrosting mode, and the outdoor heat exchanger is defrosted. After the cleaning instruction is responded, the indoor coil pipe temperature value and the outdoor coil pipe temperature value are obtained, the operation state of the air conditioner is adjusted according to the indoor coil pipe temperature value and the outdoor coil pipe temperature value, the frosting speed of the outdoor heat exchanger is increased, the outdoor heat exchanger can be frosted rapidly, and therefore the cleaning effect is improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a self-cleaning control method, device and air conditioner. Background technique [0002] With the improvement of living standards and technological levels, people have higher and higher requirements for the comfort of air conditioners. Generally, the outdoor unit of the air conditioner is installed outdoors. After the air conditioner has been running for a period of time, the heat exchanger of the outdoor unit will be covered with some impurities, which will affect the heat transfer performance of the outdoor heat exchanger, thereby affecting the comfort of the air conditioner. sex. [0003] At present, most of the cleaning methods are to run the heating mode first to make frost on the outdoor heat exchanger, and then enter the defrosting mode to clean the dust on the fin surface of the outdoor heat exchanger with defrosted water, so as to achieve the effect of...
