Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner and a self-cleaning method thereof.
Background
When the indoor unit of the air conditioner operates in a cooling or heating mode, air in the indoor environment enters the indoor unit along the air inlet of the indoor unit and is blown into the indoor environment again through the air outlet after heat exchange of the heat exchange plates, in the process, impurities such as dust, large particles and the like mixed in the indoor air can also enter the indoor machine along with the air flow of the inlet air, although the dustproof filter screen arranged at the air inlet of the indoor unit can filter most of dust and particles, but a small amount of fine dust is not completely blocked and filtered, and with the long-term use of the air conditioner, the dust will gradually deposit and adhere to the surfaces of the heat exchanger fins, and since the dust covering the outer surfaces of the heat exchanger is less thermally conductive, it directly affects the heat exchange between the heat exchange fins and the indoor air, so that the indoor unit needs to be cleaned regularly to ensure the heat exchange efficiency of the indoor unit.
Generally, a cleaning method of an air conditioner indoor unit in the prior art mainly includes two modes of manual cleaning and air conditioner self-cleaning, wherein the air conditioner self-cleaning mode is that a refrigerant of an air conditioner firstly runs in a refrigerating flow direction (a frost condensation stage), and the output quantity of the refrigerant to an indoor heat exchanger is increased, so that moisture in indoor air can be gradually condensed into a frost layer or an ice layer on the outer surface of the heat exchanger, in the process, the condensed frost layer can be combined with dust, so that the dust is stripped from the outer surface of the heat exchanger, then the refrigerant runs in a heating flow direction (a frost melting stage), so that the condensed frost layer on the outer surface of the heat exchanger is melted, and the dust can be collected into a water receiving tray along with melted water flow, and therefore, the purpose of self-cleaning of the air conditioner can be. The parameter setting in the self-cleaning process of the existing air conditioner mainly considers the frost condensation effect of a frost condensation mode and the defrosting effect of a defrosting mode, such as the speed of frost condensation, the speed of defrosting, the thickness of a condensed ice layer and the like.
Because the pollutant components on the air-conditioning heat exchangers in different areas and different seasons are different, for example, in the aspect of air-conditioning products used in different areas, in the area with more dust in the north, the dust components in the pollutants deposited on the heat exchangers are more; for the southern region with humid climate, the heat exchanger has more fungi and bacteria of the pollutants while the pollutants are still available; the pollutant composition of the same air conditioning product can also be different when the air conditioning product is used in different seasons, for example, the pollutant composition is obviously different in winter and summer, dust is mainly used in winter, and bacteria and mold are mainly used in summer. Therefore, the parameter setting mode in the self-cleaning process of the existing air conditioner often cannot achieve the optimal cleaning effect.
