Embodiment 1

[0076]

[0077] like Figure 1a , Figure 1b , Figure 1c and image 3 As shown, the present embodiment provides a filter device, comprising:

[0078] The filter screen 1 includes a first mesh 11 and a second mesh 12 that are arranged crosswise and detachable, and each of the first mesh 11 and the second mesh 12 includes multiple pieces; specifically, the first mesh 11 The expanded length and the expanded length of the second mesh 12 are greater than the length and width of the filter net;

[0079] The cleaning part includes a first cleaning part 21 and a second cleaning part 22. The first cleaning part 21 corresponds to the first mesh 11 and can remove dust on the first mesh 11. The second cleaning part 22 is connected to the second mesh. 12 corresponds to and can remove the dust on the second mesh wire 12;

[0080] A plurality of first mesh wires 11 can be controlled to move independently, one end can be deployed and the other end can be collected; a plurality of secon...

Embodiment 2

[0136] This embodiment also provides a method for controlling a filter device, the filter device is the filter device in Embodiment 1, comprising:

[0137] S3. When it is judged that the air quality in the environment where the filter screen is located is greater than the second preset value, control the first toggle mechanism and the second toggle mechanism to act.

[0138] Further, S3 includes:

[0139] S31. Control the first toggle motor A512 to drive the first toggle piece A511 to act and the first toggle motor B to drive the first toggle piece B521 to move, and the first mesh 11 moves in a direction perpendicular to the first direction;

[0140] S32. Control the second toggle motor A612 to drive the second toggle piece A611 to act and the second toggle motor B to drive the second toggle piece B621 to move, the second mesh 12 moves in a direction perpendicular to the second direction, and then filters The number of meshes of the net is reduced.

[0141] S4. When it is ju...

Embodiment 3

[0143] This embodiment also provides a method for controlling a filter device. The filter device is the filter device in Embodiment 1. The filter device is applied to an air conditioner indoor unit. The air conditioner indoor unit includes a housing that forms a There is an air inlet, and the filter screen device is arranged at the air inlet; the air conditioner indoor unit also includes a detection module, the detection module is a first wind speed sensor and a second wind speed sensor, which are used to detect the air inlet wind speed and the wind outlet wind speed of the filter screen respectively, and The detection data is sent to the controller of the air conditioner; the first wind speed sensor and the second wind speed sensor are respectively located at the air inlet end and the air outlet end of the filter; the detection module also includes an air quality sensor for detecting indoor air quality;

[0144] like Figure 4 As shown, the control methods include:

[0145] ...

Abstract

The invention provides a filter screen device, a control method and an air conditioner. The filter screen device comprises a filter screen, a first cleaning part and a second cleaning part, the filter screen comprises a first net wire and a second net wire, and the first net wire can move in the first direction under the action of a first winding and unwinding mechanism; under the action of the second winding and unwinding mechanism, the second net wire can move in the second direction; when filth blockage of the filter screen occurs, the first cleaning part can remove dust on the first net wires, and the second cleaning part can remove dust on the second net wires; the process of cleaning the filter screen is simplified, the filter screen is cleaned more thoroughly, and waste of water resources is avoided; the filter screen device further comprises a first stirring mechanism and a second stirring mechanism, according to the air quality, the first stirring mechanism stirs the first net wires to move, the second stirring mechanism stirs the second net wires to move, then the mesh number of the filter screen is adjusted, the filter capacity and the wind resistance are considered, the air inlet flow and the air inlet quality are guaranteed, and the energy efficiency of the air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a filter device, a control method and an air conditioner. Background technique [0002] It is common to use a filter to filter the air in the environment, but the filter is prone to dirty clogging after a period of use; in the prior art, one solution is to remove the filter and clean it with a brush, but this solution needs to be disassembled And reinstalling the filter screen makes the whole process complicated, time-consuming and labor-intensive; another solution is to spray water with a certain pressure to clean the filter screen, the water pressure is different, the cleaning effect is different; the water pressure is small, the cleaning effect Poor, when the water pressure is high, it will have a certain destructive effect on the filter, and at the same time require a lot of water, resulting in a waste of water resources. Contents of the invention [0...
