Embodiment 1

[0050] What is realized in this embodiment 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 air duct of the air conditioner in this embodiment includes:

[0051] S10. Turn on the cooling mode and control the first fan to run at a first speed for a first set time, so that a first water film is formed on the surface of the evaporator.

[0052] Specifically, 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 this step, the air conditioner is in the cooling mode, and the first fan is controlled 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 relatively high, The first set time length is relatively short, and when the first rotational speed is relatively small, the first set time length is rela...

Embodiment 2

[0059] For split-type air conditioners, the fans and air ducts in the indoor unit and outdoor unit will accumulate dust, so users need to regularly clean the outdoor unit in addition to the indoor unit. In order to facilitate users and save users the trouble of cleaning the air conditioner, this embodiment provides an air conditioner and its self-cleaning control method that can clean both the indoor fan and the air duct and the outdoor unit fan and air duct. In this embodiment, the outdoor unit includes a second air duct, a second fan and a first condenser. This embodiment is the same as Embodiment 1 in that the self-cleaning process of the indoor unit is exactly the same, that is, after the air conditioner starts the cooling mode, it executes three self-cleaning stages in S10-S12 to realize the self-cleaning of the indoor unit fan and air duct. The difference between this embodiment and embodiment 1 is that, referring to figure 2 , the self-cleaning control method in this ...

Embodiment 3

[0069] This embodiment is similar to Embodiment 2, and both can realize the self-cleaning of the outdoor unit of the air conditioner and the indoor unit fan and the air duct. The examples are the same, and details can be referred to Embodiment 1. The difference between this embodiment and Embodiment 2 lies in the self-cleaning process of the fan and the air duct of the outdoor unit. In this embodiment, the outdoor unit includes a third air duct, a third fan and a second condenser.

[0070] refer to image 3 In addition to the method in Embodiment 1, the self-cleaning control method of the fan and air duct in this embodiment also includes:

[0071] S30. Switch the cooling mode to the heating mode and control the third fan to run at the eighth speed for a seventh set time, so that a third water film is formed on the surface of the second condenser.

[0072] Specifically, this step can be referred to as the fourth stage of the self-cleaning process, that is, the stage where th...

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 use. The control method comprises the steps: starting a refrigeration mode, controlling a first fan to run at afirst rotating speed for a first set duration, and forming a first water film on the surface of an evaporator; controlling the first fan to reversely run for a second set duration at a second rotating speed, so that dust attached to the fan and the air duct can be thrown out and attached to the first water film; controlling the first fan to operate for a third set duration at a third rotating speed, so that flowing condensate water can be formed on the surface of the evaporator, and dust is discharged by virtue of the flowing condensate water, wherein the second rotating speed is greater thanthe first rotating speed and the third rotating speed. According to the control method provided by the invention, the automatic cleaning of dust in the fan and the air duct of the indoor unit can berealized, a disassembling and assembling machine is not needed, a special cleaning tool is not needed, and the dust cleaning 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...
