Embodiment Construction
[0063]Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments as needed so as to adapt to specific applications. For example, although it is described in the specification that the indoor fan is a cross-flow fan as an example, the indoor fan of the present invention can obviously adopt other types of fans, such as axial flow fans, as long as it can blow air indoors.
[0064] First refer to Figure 1 to Figure 3 , to describe the self-cleaning control method of the air duct of the air conditioner of the present invention. in, figure 1 It is a structural schematic diagram of the first air duct of the air conditioner of the present invention, figure 2 It is a ...

The invention belongs to the field of air conditioners, particularly provides a self-cleaning control method for air ducts of an air conditioner and aims to solve a problem that in the prior art, theair duct of the air conditioner can only be manually cleaned to guarantee user experience. The control method comprises steps that the air conditioner is controlled to enter a refrigeration cycle mode; whether the condensate water is formed on a surface of an indoor heat exchanger is determined; when the condensate water is formed on the surface of the indoor heat exchanger, an indoor fan is controlled for blowing the air reversely at the speed of V1; the air conditioner is controlled for entering a heating cycle mode; whether the condensate water is formed on a surface of an outdoor heat exchanger is determined; when the condensate water is formed on the surface of the outdoor heat exchanger, an outdoor fan is controlled for blowing the air reversely at the speed of V2. The method is advantaged in that impurities in a first air duct and a second air duct are blown to the heat exchangers under the action of wind power by combining reverse rotation of the indoor fan with the condensatewater of the indoor heat exchanger and then adsorbed by the condensate water on the surface of the heat exchanger, so a purpose of cleaning the air ducts is achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air duct of an air conditioner. Background technique [0002] During the use of the air conditioner, it is inevitable that there will be dust accumulation in the air duct, and the more serious the dust accumulation, the more the indoor air quality will be degraded, causing troubles to customers. [0003] In the prior art, there are usually two ways to remove dust accumulation, one is to use professional tools to go deep into the air-conditioning air duct to wipe, and the other is to design the air duct in a detachable form, and clean it after disassembling. However, both of them have a big disadvantage, that is, maintenance personnel must come to the site to provide service, which will increase the maintenance cost of the product, increase the user's payment fee, and bring a poor experience to the user.
