[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] The embodiment of the present application provides a filter screen assembly to solve the problem of a small air inlet area of ​​a straight structure filter screen 5. The filter screen assembly will be described below in conjunction with the accompanying drawings.

[0035] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the filter screen assembly includes a bracket 101 and a filter screen 5 .

[0036] A plurality of protruding structures 2 are provided on one side of the bracket 101, and at least two protruding structures 2 are arranged adjacently and spaced apart to form a avoidance portion 3. Here, one side of the bracket 101 may refer to one side of the bracket 101 along its thickness direction. In some embodiments, among the plurality of protruding structures 2, some of the protruding structures 2 may be arranged adjacently and spaced apart to form a avoidance portion between two adjacent ones, while the remaining protruding structures 2 may be arranged adjacently and remain connected so that there is no avoidance portion 3 between the two adjacent ones. In other embodiments, among the plurality of protruding structures 2, any two adjacent protruding structures 2 are arranged at intervals so that a avoidance portion 3 is provided between any two adjacent protruding structures 2.

[0037] The filter screen 5 is extended to the plurality of raised structures 2 and the avoidance portion 3. Here, the filter screen 5 can be extended along the surface of the plurality of raised structures 2 and the avoidance portion 3, so that the filter screen 5 can fit over the plurality of raised structures 2 and the avoidance portion 3, thereby forming a concave and convex structure of the filter screen 5. In some embodiments, the filter screen 5 can be integrally arranged with the bracket 101, and the entire filter screen assembly can be removed at one time for cleaning.

[0038] Compared with the filter screen 5 with a straight structure in the related art, the filter screen assembly provided in the embodiment of the present application can form an uneven structure of the filter screen 5 by setting a protruding structure 2 and a avoiding portion 3 on the bracket 101, and setting the filter screen 5 at multiple protruding structures 2 and avoiding portions 3, so that the filter screen 5 has a larger area than the straight structure, and the avoiding portions 3 between adjacent protruding structures 2 play the role of avoiding the internal structure of the air conditioner indoor unit, so that the filter screen assembly can better match the internal structure of the air conditioner indoor unit. The number of protruding structures 2 and the position of the avoiding portion 3 can be designed and adjusted accordingly according to the internal structure of the air conditioner indoor unit.

[0039] In some embodiments, Figure 3As shown, the avoidance portion 3 includes a first avoidance sub-portion 31 and a second avoidance sub-portion 32 which are arranged alternately, the first avoidance sub-portion 31 extends along the first direction, and the second avoidance sub-portion 32 extends along the second direction; a plurality of protrusion structures 2 are sequentially arranged at intervals along the first direction to form the second avoidance sub-portion 32, and sequentially arranged at intervals along the second direction to form the first avoidance sub-portion 31, the first direction is the width direction of the bracket 101, and the second direction is the length direction of the bracket 101. Here, some of the protrusion structures 2 can be adjacent and spaced along the first direction and the second direction to form the first avoidance sub-portion 31 or the second avoidance sub-portion 32 between the two adjacent ones, and different protrusion structures 2 can be arranged at intervals of different distances to form the first avoidance sub-portion 31 or the second avoidance sub-portion 32 with different lengths and widths, which is more in line with the irregular configuration of the internal structure of the air conditioner indoor unit. Some of the raised structures 2 may be arranged side by side along the first direction, and / or some of the raised structures 2 may be arranged side by side along the second direction to form avoidance portions with different staggered structures such as a cross or T-shape.

[0040] The avoidance portion 3 is further configured as a first avoidance sub-portion 31 and a second avoidance sub-portion 32, and extends in a first direction and a second direction perpendicular to each other, respectively, to adapt to the internal structures in different directions of the air conditioner indoor unit. At the same time, the first avoidance sub-portion 31 and the second avoidance sub-portion 32 are staggered to further increase the avoidance area.

[0041] In some embodiments, Figure 3 As shown, the width of the first avoidance sub-portion 31 is smaller than the width of the second avoidance sub-portion 32; when the filter assembly is applied to an air conditioner indoor unit, the second avoidance sub-portion 32 is used to avoid the evaporator of the air conditioner indoor unit, and the first avoidance sub-portion 31 is used to avoid the rib 42 of the air conditioner indoor unit. Here, different protrusion structures 2 can be arranged at different distances along the second direction to form first avoidance sub-portions 31 of different lengths and widths.

[0042] The air inlet 41 of the air conditioner indoor unit is provided with ribs 42 to improve the structural strength of the air conditioner indoor unit casing 4 in the width direction. Based on this, the first avoidance sub-portion 31 extending along the first direction is used to avoid the ribs 42. The length direction of the air conditioner indoor unit evaporator is consistent with the length direction of the casing 4, and the second avoidance sub-portion 32 extending along the second direction is used to avoid the evaporator. The width of the first avoidance sub-portion 31 is smaller than the width of the second avoidance sub-portion 32 to adapt to the smaller width of the ribs 42 compared to the evaporator. The number of the first avoidance sub-portions 31 can be equal to or greater than the number of the ribs 42.

[0043] In some embodiments, Figure 3As shown, multiple protrusion structures 2 are symmetrically arranged about the width center of the bracket 101. Here, symmetrical arrangement means that after the filter assembly is folded in half about the width center of the bracket 101, multiple protrusion structures 2 located on both sides of the width center of the bracket 101 can overlap, and the avoidance parts 3 located on both sides of the width center of the bracket 101 can also overlap, and the structure is simple and easy to produce and process. At the same time, the filter 5 covered by the protrusion structure 2 and the avoidance part 3 is symmetrical about the width center of the bracket 101, so that the filter 5 has the same air inlet area on both sides of the width center of the bracket 101.

[0044] In some embodiments, Figure 3 As shown, the protruding structure 2 includes two relative extension plates 21 and a connecting rib 22 connected between the two extension plates 21. Here, the two extension plates 21 of the protruding structure 2 can be arranged relatively along the first direction, the second direction, the thickness direction of the bracket 101 or other directions, and the connecting rib can adopt a straight structure, a curved structure or a wavy structure, and the connecting rib can be connected to the middle or edge of the extension plate. The angle between the extension plate 21 and the bracket 101 can be 90 degrees, or greater than or less than 90 degrees. The length and width of the extension plate 21, the length of the connecting rib 22, and the angle between the extension plate 21 and the bracket 101 can be adjusted according to the internal structure of the air conditioner indoor unit. Along the second direction, the shapes of different protruding structures 2 can also be different.

[0045] The extension plate 21 forms a protrusion protruding from the bracket 101 , and the connection ribs 22 improve the stability of the extension plates 21 disposed opposite to each other.

[0046] In some embodiments, Figure 3As shown, the bracket 101 includes a frame body 1, a plurality of protrusion structures 2 are arranged on a side surface of the frame body 1, and an extension plate 21 has a first end edge 211 and a second end edge 212 arranged opposite to each other, the first end edge 211 is connected to the frame body 1, and the second end edge 212 protrudes in a direction away from the first end edge 211, and the second end edges 212 of the two extension plates 21 are connected by a connecting rib 22, and the filter 5 is connected to the second end edge 212. Here, a side surface of the frame body 1 refers to a side perpendicular to the length direction and the width direction of the frame body 1. The protrusion is formed by the second end edge 212, and it can protrude from both ends or the middle of the second end edge 212 relative to the first end edge 211. The second end edge 212 can be one of an arc, a wave shape, an inverted triangle, or a combination thereof, and the shape of the second end edge 212 can be designed according to the internal space of the air conditioner indoor unit. The filter screen 5 is connected to the second end edge 212, so that the filter screen 5 has an undulating shape consistent with the second end edge 212, and a filter screen 5 with a larger air inlet area is formed compared to a filter screen 5 with a straight structure, or compared to a filter screen 5 arranged between the first end edge 211 and the second end edge 212. In some embodiments, the filter screen 5 can be connected between the two extension plates 21 and the connecting ribs 22, or can be connected to the outside of the two extension plates 21 and the connecting ribs 22 to cover the protruding portion of the protruding structure 2, and the configurations of the two extension plates 21 of the protruding structure 2 can be the same or different.

[0047] In some embodiments, Figure 3 As shown, the two extension plates 21 of the protruding structure 2 are arranged opposite to each other along a first direction, and the second end edge 212 is an arc-shaped structure. The first direction is the width direction of the bracket 101.

[0048] Due to the structure of the second end edge 212, the two extension plates 21 of the protruding structure 2 are arranged relative to each other along the first direction. Compared with the relative arrangement along the length direction of the bracket 101, the partial area of ​​the avoidance portion 3 along the length direction of the bracket 101 has a larger space, which can adapt to the internal structure of the air-conditioning indoor unit with a larger volume and more complex structure.

[0049] In some embodiments, Figure 3 As shown, the filter 5 includes a curved filter part 51 and a straight filter part 52, the curved filter part 51 is connected to the protruding structure 2, and the straight filter part 52 is connected to the frame body 1 and covers at least part of the avoidance part 3. Here, the curved filter part 51 refers to a filter 5 having the same structure as the second end edge 212, and the straight filter part 52 refers to a flat filter 5 adapted to the structure of the avoidance part 3, so that the filter 5 covers the entire bracket 101 to ensure the filtering function of the filter assembly. The curved filter part 51 and the straight filter part 52 can be integrally formed or separately arranged.
