Embodiment Construction
[0040] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can adjust it as needed 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.
[0041] refer to figure 1 and figure 2 , 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 schematic structural view of the air duct of the air conditioner of the present invention, figure 2 It is the main flow chart...

The invention belongs to the field of air conditioners, and specifically provides a self-cleaning control method for an air duct of an air conditioner. The invention aims to solve the problem in the prior art that the air duct of the air conditioner can only be cleaned manually to ensure user experience. The air conditioner of the present invention includes an indoor heat exchanger, an indoor fan, and an air duct arranged in sequence. The air enters the indoor fan after exchanging heat through the indoor heat exchanger, and enters the air duct with the operation of the indoor fan, and finally blows to the room. It is a two-way fan, the air is blown to the room through the indoor heat exchanger in the forward direction, and the air is blown from the indoor to the indoor heat exchanger in the reverse direction. The control method includes: controlling the air conditioner to enter the refrigeration cycle; determining whether the surface of the indoor heat exchanger is formed Condensed water; when condensed water is formed on the surface of the indoor heat exchanger, the indoor fan is controlled to blow in reverse at V1 speed. According to the invention, the sundries in the air duct are blown to the indoor heat exchanger under the action of wind force, and then absorbed by the condensed water on the surface of the indoor heat exchanger, thereby cleaning the air duct.
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. [0004] Correspondi...
