Abstract

The invention discloses an air conditioner and a self-cleaning control method thereof, and belongs to the technical field of air conditioners. The control method comprises the following steps: obtaining the current indoor temperature when the air conditioner operates a frosting stage of an indoor unit cleaning mode; adjusting the operating parameter of at least one part of the air conditioner based on the temperature difference between the current indoor temperature and the initial indoor temperature when the air conditioner starts the indoor unit cleaning mode; and after a defrosting switching condition is satisfied, controlling the air conditioner to enter a defrosting stage of the indoor unit cleaning mode, and controlling to start an indoor unit electric heating device. According to the self-cleaning control method for the air conditioner provided by the invention, the operating parameter of the air conditioner is adjusted according to the indoor temperature detected in the frosting stage of the self-cleaning mode so as to maintain the temperature difference between the indoor temperature and the initial indoor temperature when the air conditioner starts the indoor unit cleaning mode within a preset temperature difference range; therefore, the indoor environment cannot produce great temperature fluctuation in the frosting stage of self-cleaning of the air conditioner; and the user experience of a user when the air conditioner executes the self-cleaning mode can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a self-cleaning control method thereof. Background technique [0002] When the air conditioner is running in the cooling or heating mode, the air in the external environment enters the inside of the body along the air inlet, and is blown back into the external environment through the air outlet after the heat exchange fins exchange heat. In this process, all the air in the air Impurities such as dust and large particles will also enter the interior of the indoor unit along with the air intake. Although the dust filter installed at the air inlet of the air conditioner can filter most of the dust and particles, there will still be a small amount of tiny dust It cannot be completely blocked and filtered. With the long-term use of the air conditioner, these dusts will gradually deposit and adhere to the surface of the heat exchange fins. Due to the poo...
