Embodiment 1

[0045] What this embodiment realizes is the automatic dust cleaning process of the fan and the air duct of the indoor unit. refer to figure 1 , the self-cleaning control method of the fan and the air duct of the air conditioner in the present embodiment includes:

[0046] S10. Control the fan to run at a first rotational speed for a first set time, so as to form a water film on the surface of the heat exchanger.

[0047] Specifically, since this embodiment realizes the self-cleaning process of the indoor unit fan and the air duct, the self-cleaning control method in this embodiment operates in the cooling mode of the air conditioner. This step can be called the first stage of the self-cleaning process, that is, the stage where the indoor unit forms an adsorbed water film. In the process of controlling the fan of the indoor unit to run at the first speed for the first set time, the first set time and the first speed are related to each other. When the first speed is relativel...

Embodiment 2

[0056] This embodiment still takes the realization of the self-cleaning process of the indoor unit fan and the air duct as an example. refer to figure 2 , the self-cleaning control method of the fan and the air duct of the air conditioner in the present embodiment includes:

[0057] S20. Control the fan to run at the first rotational speed for a first set time, so as to form a water film on the surface of the heat exchanger.

[0058] Specifically, since this embodiment also realizes the self-cleaning process of the indoor unit fan and the air duct, the self-cleaning control method in this embodiment needs to be operated in the cooling mode of the air conditioner. This step can be called the first stage of the self-cleaning process, that is, the stage where the indoor unit forms an adsorbed water film. In the process of controlling the fan of the indoor unit to run at the first speed for the first set time, the first set time and the first speed are related to each other. Wh...

Abstract

The invention relates to the technical field of air conditioners and provides an air conditioner and a self-cleaning control method for an fan and air duct thereof to solve the problems that the and air duct of an existing air conditioner are high in dust removal cost and inconvenient to us. The control method comprises the steps: controlling the fan to run at a first rotating speed for a first set duration to form a water film on the surface; controlling the fan to operate reversely at a second rotating speed and then operate at a third rotating speed, and circularly executing the step at least once, so that dust attached to the fan and the air flue can be thrown out and attached to the water film; and controlling the fan to operate for a third set duration at a fourth rotating speed, sothat flowing condensate water can be formed on the surface of the heat exchanger, and dust is discharged by means of the flowing condensate water. According to the control method provided by the invention, deep self-cleaning of dust in fans and air ducts of the indoor unit and the outdoor unit can be achieved, a disassembling and assembling machine is not needed, a special cleaning tool does not need to be arranged, and the dust removal cost can be greatly reduced.

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 for a fan and an air duct thereof. Background technique [0002] The air conditioner is one of the essential household appliances in modern families to improve the indoor environment. Household air conditioners are usually split wall-mounted, including an indoor unit and an outdoor unit. The indoor unit is usually equipped with a cross-flow fan to evenly expand the horizontal blowing range, and the outdoor unit is usually equipped with an axial-flow fan. [0003] After the air conditioner is used for a period of time, no matter the indoor unit or the outdoor unit, the fan impeller and the air duct are prone to dust accumulation, and bacteria are easy to breed after a long time. Among them, the dust on the indoor unit fan and the air duct will be blown into the room, reducing the Indoor air quality is very unfavorable...
