[0077] like Figure 1a , Figure 1b , Figure 1c and Figure 3 As shown, this embodiment provides a filter device, including:

[0078] The filter screen 1 comprises a first mesh wire 11 and a second mesh wire 12 which are arranged crosswise and can be separated, and each of the first mesh wire 11 and the second mesh wire 12 comprises a plurality of wires; specifically, the unfolded length of the first mesh wire 11 and the unfolded length of the second mesh wire 12 are both greater than the length and width of the filter screen;

[0079] The cleaning member includes a first cleaning member 21 and a second cleaning member 22, wherein the first cleaning member 21 corresponds to the first mesh 11 and can remove dust on the first mesh 11, and the second cleaning member 22 corresponds to the second mesh 12 and can remove dust on the second mesh 12;

[0080] Multiple first meshes 11 can be controlled to move independently, one end of which can be unfolded and the other end can be collected; multiple second meshes 12 can be controlled to move independently, one end of which can be unfolded and the other end can be collected. When the first mesh 11 is controlled to move, the first cleaning member 21 can remove dust on the first mesh 11; when the second mesh 12 is controlled to move, the second cleaning member 22 can remove dust on the second mesh 12; the process of cleaning the filter is simplified, not limited by seasonal environment, avoiding the waste of water resources, and avoiding the risk of short circuit of other electrical components when using water to clean the filter; different meshes can be controlled to move independently, and different cleaning members can remove dust on the filter, improving the effect of cleaning the filter; the present application removes dust on the filter one by one for the first mesh 11 and the second mesh 12 constituting the filter, and removes dust more thoroughly.

[0081] In order to realize the movement of the first mesh 11 and remove dust on the first mesh 11, the filter device includes a first winding and unwinding mechanism;

[0082] The two ends of the first mesh 11 are respectively wound on different parts of the first reeling and unreeling mechanism. Under the action of the first reeling and unreeling mechanism, one end of the first mesh 11 is collected and the other end of the first mesh 11 is unfolded.

[0083] Further, the first winding and unwinding mechanism includes a first winding assembly 31 and a first unwinding assembly 32 which are arranged opposite to each other; specifically, the first winding assembly 31 and the first unwinding assembly 32 are respectively arranged on both sides of the filter screen along the first mesh wire 11; the first winding assembly 31 includes a first winding shaft 311, and the first unwinding assembly 32 includes a first unwinding shaft 321; one end of the first mesh wire 11 is wound on the first winding shaft 311, and the other end of the first mesh wire 11 is wound on the first unwinding shaft 321;

[0084] When the first reeling shaft 311 or the first unreeling shaft 321 is driven to rotate, the first mesh 11 moves, and the first cleaning member 21 can remove dust on the first mesh 11. The two ends of the first mesh 11 are respectively collected and unfolded.

[0085] Preferably, the first winding assembly 31 further includes a first winding drive motor 312 drivingly connected to the first winding shaft 311, and the first unwinding assembly 32 further includes a first coil spring 322 connected to the first unwinding shaft 321;

[0086] When the first winding drive motor 312 drives the first winding shaft 311 to rotate, one end of the first mesh 11 is collected, the first mesh 11 moves along the first direction, the other end of the first mesh 11 is unfolded, the first unwinding shaft 321 rotates, and then the first coil spring 322 stores energy;

[0087] When the first winding drive motor 312 is not in operation and / or powered off, the first coil spring 322 releases energy and drives the first unwinding shaft 321 to rotate, the other end of the first mesh 11 is collected, the first mesh 11 moves in a direction opposite to the first direction, one end of the first mesh 11 is unfolded, and the first mesh 11 is reset; specifically, the first coil spring 322 needs to be pre-tightened first, and during its operation, its minimum pre-tightening torque is greater than the self-positioning torque of the first winding drive motor 312.

[0088] In order to make the first cleaning member 21 remove dust on the first mesh 11 more thoroughly, the first cleaning member 21 is disposed between the first winding assembly 31 and the filter screen, and / or between the first unwinding assembly 32 and the filter screen;

[0089] The first cleaning member 21 is formed with a first dust cleaning portion 212; the first mesh 11 can pass through the first dust cleaning portion 212;

[0090] When the first mesh 11 moves, the first dust cleaning part 212 can separate the dust on the first mesh 11 from the first mesh 11, so as to achieve the purpose of removing the dust on the first mesh 11;

[0092] The mesh size of the filter is different, and the filtration level of the air passing through is different. The more mesh size the filter has per unit area, the higher the filtration level and the better the air filtering effect, but the wind resistance is greater, which affects the ventilation volume.

[0093] In order to achieve that the mesh number of the filter can be adjusted in a direction at a certain angle to the first direction, the filter device also includes a first toggle mechanism respectively arranged on both sides of the filter; the first toggle mechanism toggles the first mesh wire 11 in a direction at a certain angle to the first direction, thereby changing the mesh number of the filter or changing the spacing between two adjacent first mesh wires 11; preferably, under the action of the first toggle mechanism, the first mesh wire 11 moves in a direction perpendicular to the first direction; according to actual needs, such as geographical environment, time period and air quality, the movement direction of the first mesh wire 11 can be reasonably controlled to increase or decrease the mesh number of the filter, taking into account the filtering capacity and wind resistance, while ensuring the air intake flow rate and air intake quality, and improving the cooling and heating efficiency of the air conditioner; the problem that the mesh number of the filter cannot be adjusted and cannot adapt to air of different qualities is solved.

[0109] When the second mesh 12 moves, the second dust cleaning part can separate the dust on the second mesh 12 from the second mesh 12, so as to achieve the purpose of removing the dust on the second mesh 12;

[0110] Preferably, the second cleaning member 22 is formed with a second cleaning plate and a second ash collecting trough, a second cleaning portion is formed on the second cleaning plate, the second cleaning portion is a hole-type structure, the aperture of the second cleaning portion is slightly larger than the diameter of the second mesh; the number of the second cleaning portions is the same as the number of the second meshes 12, and the second meshes 12 pass through the second cleaning portion; the second ash collecting trough is arranged at the bottom of the second cleaning plate; the second mesh 12 passes through the second cleaning portion, and when the second mesh 12 is controlled to move, the dust on the second mesh 12 is filtered out by the second cleaning portion and falls into the second ash collecting trough; at this time, condensed water can be added to the second ash collecting trough to clean the dust in the second ash collecting trough, or a vacuum cleaner can be used to suck away the dust in the second ash collecting trough, so as to achieve the purpose of completely removing the dust.

[0111] In order to achieve that the mesh number of the filter can be adjusted in a direction at a certain angle to the second direction, the filter device also includes a second toggle mechanism respectively arranged on the other two sides of the filter; the second toggle mechanism toggles the second mesh wire 12 in a direction at a certain angle to the second direction, thereby changing the mesh number of the filter or changing the spacing between two adjacent second mesh wires 12; preferably, under the action of the second toggle mechanism, the second mesh wire 12 moves in a direction perpendicular to the second direction; according to actual needs, such as geographical environment, time period and air quality, the movement direction of the second mesh wire 12 can be reasonably controlled to increase or decrease the mesh number of the filter.

[0112] Further, if Figure 1a , Figure 1b , Figure 1c and Figure 2As shown, the second toggle mechanism includes a second toggle assembly A61 and a second toggle assembly B62, which are respectively arranged on one side of the second winding assembly 41 and one side of the second unwinding assembly 42;

[0113] The second toggle assembly A61 includes a second toggle member A611 and a second toggle motor A612 for driving the second toggle member A611 to move; the second toggle assembly B62 includes a second toggle member B621 and a second toggle motor B for driving the second toggle member B621 to move;

[0114] The second toggle motor A612 drives the second toggle member A611 to move, and at the same time the second toggle motor B drives the second toggle member B621 to move, and the second toggle motor A612 and the second toggle motor B rotate in the same direction, and the second mesh wire 12 moves in a direction perpendicular to the second direction.

[0115] Preferably, the second toggle member A611 and the second toggle member B621 are both cylindrical structures as a whole, and a second through groove 622 is formed on one side of the second toggle member B621, and a plurality of second toggle posts 63 tangential to the cylindrical structure are formed at the second through groove 622, and the number of the second toggle posts 63 is less than the number of the second mesh wires 12; specifically, the number of the second toggle posts 63 is half the number of the second mesh wires 12, and the second toggle posts 63 are arranged corresponding to the second mesh wires 12; when the second toggle motor A612 drives the second toggle member A611 to move and the second toggle motor B drives the second toggle member B621 to move, the second toggle post 63 toggle the corresponding second mesh wire 12 to merge with the adjacent second mesh wire 12, and the mesh number of the filter screen is reduced;

[0116] When the second toggle motor A612 drives the second toggle member A611 to move and the second toggle motor B drives the second toggle member B621 to move, the second toggle column 63 toggle the corresponding second mesh wire 12 to separate from the adjacent second mesh wire 12, and the mesh count of the filter increases.

[0117] In order to reduce the space occupied by the filter device, the second toggle member B621 is sleeved on the second unwinding shaft 421, and the second toggle member B621 is not connected to the second unwinding shaft 421, and the second toggle motor B drives the second toggle member B621 to rotate and the second coil spring 422 drives the second unwinding shaft 421 to rotate without interfering with each other; the second toggle member A611 is arranged between the second cleaning member 22 and the filter to reduce the influence of the second cleaning member 22 on the second mesh 12 when the second toggle member A611 is actuated.

[0118] When the filter is dirty and clogged, the wind resistance coefficient increases, and then the wind resistance increases, affecting the ventilation volume. The degree of dirtiness and clogs of the filter can be determined by calculating the difference between the inlet and outlet wind speeds of the filter, and then the first and second retracting and unwinding mechanisms are controlled to operate and remove dust from the filter.

[0119] The mesh size of the filter can be adjusted according to the air quality, taking into account the filtering capacity and wind resistance, ensuring the air flow and quality, and improving the energy efficiency of the air conditioner;

[0120] The first toggle mechanism and the second toggle mechanism include a linear motor and a toggle member, or a cam mechanism, or a gear rack mechanism, or a crank slider mechanism; but are not limited to the above mechanisms.

[0121] When the mesh number of the filter is a multiple of 4, the mesh number of the filter can be adjusted to 1 / 4 of the original by moving the first mesh wire 11 through the first toggle mechanism and moving the second mesh wire 12 through the second toggle mechanism at the same time; when the mesh number of the filter is a multiple of 2, the mesh number of the filter can be adjusted to 1 / 2 of the original by moving the first mesh wire 11 through the first toggle mechanism or moving the second mesh wire 12 through the second toggle mechanism; it should be noted that the change in the mesh number of the filter is not limited to the above-mentioned change rules, and different mesh numbers of the filter have different change rules.
