Problems solved by technology
The dirt adheres to the heat exchanger of the indoor unit. On the one hand, it will reduce the heat transfer performance of the heat exchanger, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users
[0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt on t

Embodiment Construction
[0029] figure 1 is a schematic functional block diagram of the air conditioner 10 according to one embodiment of the present invention. figure 2 is a schematic diagram of the refrigeration system of the air conditioner 10 according to one embodiment of the present invention.
[0030]The air conditioner 10 can generally include an air conditioner indoor unit 100 and an air conditioner outdoor unit 200. The air conditioner indoor unit 100 and the air conditioner outdoor unit 200 can complete the refrigeration and heating cycles of the air conditioner through effective cooperative operation, thereby realizing the living room. Heating and cooling regulation of internal temperature. The refrigerating system of the air conditioner 10 can be realized by using a compression refrigerating cycle, which utilizes the compression phase change cycle of the refrigerant in the compressor 250 , condenser, evaporator, and throttling device 240 to transfer heat. The refrigeration system can a...

The invention provides an air conditioner and a self-cleaning control method of an indoor unit of the air conditioner. An indoor unit heat exchanging assembly of the air conditioner comprises a first indoor heat exchanger and a second indoor heat exchanger which are in tandem connection. The second indoor heat exchanger is connected to a compressor through a refrigerant flow direction switching device. An electronic expansion valve is arranged between the first indoor heat exchanger and the second indoor heat exchanger. The control method comprises the following steps that a trigger signal that the air conditioner starts a self-cleaning function is received, and the refrigerant flow direction switching device is adjusted to a state that the compressor provides a compress refrigerant for the indoor unit heat exchanging assembly; by adjusting the opening degree of the electronic expansion valve, the first indoor heat exchanger is made to conduct refrigerating firstly and then heating so as to constantly frost on the surface of the first indoor heat exchanger in a refrigerating stage; and defrosting is conducted in a heating stage, attached contaminants are taken away by water formed by defrosting, and self cleaning of the first indoor heat exchanger is achieved. According to the scheme, drastic fluctuation of temperature is avoided, and better using experience is brought to users.
Description
technical field [0001] The invention relates to a household air conditioner, in particular to an air conditioner and a self-cleaning control method for an indoor unit thereof. Background technique [0002] After the air conditioner is placed or used for a long time, there will be a lot of dust and dirt in the room. The dust attached to the heat exchanger of the indoor unit will reduce the heat transfer performance of the heat exchanger on the one hand, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users. [0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt on the heat exchanger of the air c...
