Example Embodiment

[0049] Example 1

[0050] In this embodiment, the automatic cleaning process of the fan and air duct of the indoor unit is realized. Reference 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 refrigeration mode and control the first fan to operate at a first rotation speed for a first set time period, so that a first water film is formed on the surface of the evaporator.

[0052] Specifically, this step can be referred to as the first stage of the self-cleaning process, that is, the stage where the indoor unit forms an adsorption water film. In this step, the air conditioner is in the cooling mode, and in the process of controlling the first fan to operate at the first speed for a first set time, the first set time and the first speed are related to each other. When the first speed is relatively large, The first set time period is relatively short, and when the first rotation speed is rel...

Example Embodiment

[0058] Example 2

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

Example Embodiment

[0068] Example 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 fan and the air duct of the indoor unit. This embodiment is similar to Embodiment 2 in the self-cleaning process of the indoor unit, which is the same as that of Embodiment 1. The examples are the same, please refer to Example 1 for details. The difference between this embodiment and the second embodiment lies in the self-cleaning process of the fan and 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] Reference image 3 In addition to the method of embodiment 1, the self-cleaning control method of 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 operate at the eighth speed for the seventh set time period, so that a third water film is formed on 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...
