[0035] In the prior art, most air conditioners use a flat filter. With the same cross-sectional area, the windward area of the filter is small, and the relative air intake volume is small. Experimental tests have shown that when the flat filter is dirty and clogged, the air volume rate loss is large.
[0036] See also Figure 1-Figure 2 , the embodiment of the present application provides a filter screen, comprising:
[0037] The grid 100 has connecting ribs, and the connecting ribs have a corrugated structure 1024;
[0038] The corrugated filter screen 200 is disposed on the grid frame 100 and connected to the connecting ribs, and the corrugated filter screen 200 is adapted to the corrugated structure 1024 .
[0039] It can be understood that there can be one or more connecting ribs 102, and each connecting rib 102 is fixed in the area enclosed by the grid 100. The fixing method can be welding, hot melt connection, bolt connection or bonding. The connecting ribs 102 support the grid 100, so that the overall structure of the grid 100 is stable and firm.
[0040] It can be understood that the connecting rib 102 has a corrugated structure 1024, and the connecting rib 102 itself may be a corrugated structure 1024, or the connecting rib 102 may include a connecting plate and a corrugated structure 1024, and both ends of the connecting plate are fixed on the grid 100, and the corrugated structure 1024 is fixed on any side of the connecting plate along the thickness direction of the grid 100. Preferably, the outer side surface of the connecting plate is flush with the outer side surface of the grid 100, and the corrugated structure 1024 is fixed to the inner side surface of the connecting plate, and the outer side surface of the overall grid 100 is flat, stable, beautiful and easy to process. It should be noted that the outer side surface here refers to the surface of the component (connecting plate or grid) facing the outside after the filter is installed on the air conditioner.
[0041] It can be understood that the corrugated structure 1024 includes one or more of a continuous N-shape, a continuous V-shape, a continuous S-shape, a continuous W-shape and a continuous arc shape. These continuous corrugated structures 1024 can be conveniently connected with a corrugated filter 200 that matches it. Specifically, the connection method can be bonding, or the corrugated filter 200 can be attached to the mold during the mold injection molding process and injection molded together with the grid 100 to form a complete filter product.
[0042] It can be understood that the corrugated filter 200 includes one or more of a continuous N-shape, a continuous V-shape, a continuous S-shape, a continuous W-shape and a continuous arc-shape. These continuous corrugated structures 1024 can effectively increase the air inlet area, increase the air intake volume of the air conditioner and reduce the wind loss caused by blockage.
[0043] It can be understood that the corrugated filter screen 200 can be formed by pre-pressing a mesh material, wherein the mesh material can be polyethylene terephthalate (PET) or polypropylene (PP).
[0044] Compared with the prior art, the filter provided in the present application, whose corrugated filter 200 can effectively increase the air intake area, improve the air intake volume of the air conditioner and reduce the wind loss caused by blockage; by making the corrugated filter 200 compatible with the corrugated structure 1024, the corrugated filter 200 can be fixed on the frame 100 with the aid of the corrugated structure 1024, so that the corrugated filter 200 is stable and firm.
[0045] See also Figure 1 , Figure 2 and Figure 4 The corrugated filter screen 200 includes wave crests and wave troughs and a transition section between the wave crests and the wave troughs.
[0046] It can be understood that the corrugated filter 200 is formed by the crests and troughs being smoothly connected through a transition section. The crests, troughs and transition section are integrally formed for easy processing, and the entire corrugated filter 200 is stable and firm.
[0047] The arc radius of the crest of the corrugated filter 200 is greater than the arc radius of the trough.
[0048] It can be understood that the arc radius of the crest of the corrugated filter 200 is set larger than the arc radius of the trough. When dust accumulates in the trough, the crest where dust is not accumulated can still pass through the airflow, preventing the user from not cleaning the corrugated filter 200 for too long and the air volume passing through the corrugated filter 200 from being too low.
[0049] The arc radius of the wave crest is 2 to 4 mm, for example, it can be 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, etc.
[0050] The arc radius of the trough is 0.5-1.95mm, for example, it can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 1.95mm, etc., which is conducive to the airflow passing through the crest and further reducing the wind loss caused by blockage.
[0051] The aperture of the corrugated filter 200 at the wave crest is larger than the aperture of the corrugated filter 200 at the wave trough.
[0052] It can be understood that the arrangement in which the aperture of the corrugated filter 200 at the crest is larger than the aperture of the corrugated filter 200 at the trough can better prevent dust from passing through the dust-accumulated part of the corrugated filter 200.
[0053] The aperture of the corrugated filter 200 at the wave crest is 0.7-1 mm, for example, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, etc.
[0054] The aperture of the corrugated filter 200 at the trough is 0.3 to 0.69 mm, for example, it can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.62 mm, 0.65 mm, 0.68 mm, 0.69 mm, etc. Within the aperture range of the corrugated filter 200 at the peaks and troughs, dust can be prevented from passing through the dust-accumulated part of the corrugated filter 200.
[0055] See also Figure 1 , Figure 3 and Figure 5 In some embodiments, the grid 100 is arc-shaped, and the extension direction of the arc is consistent with the extension direction of the corrugated structure 1024.
[0056] It can be understood that the arc extension direction of the frame 100 is consistent with the extension direction of the corrugated structure 1024, that is, the curvature of the frame 100 is consistent with the curvature of the corrugated structure 1024. Therefore, the overall appearance of the filter is arc-shaped and has a large surface area, which can further increase the air inlet area, further increase the air intake volume of the air conditioner and reduce the wind loss caused by blockage.
[0057] See also Figure 3 and Figure 4 In some embodiments, along the length direction of the filter screen, the corrugated structure 1024 includes a support portion 1025 and a connecting portion 1026 connected to the support portion 1025 , the support portion 1025 and the connecting portion 1026 are both connected to the corrugated filter screen 200 , and the wall thickness of the connecting portion 1026 is smaller than the wall thickness of the support portion 1025 .
[0058] It can be understood that the corrugated filter screen 200 is integrated with the corrugated structure 1024 through an injection molding process, and the portion of the corrugated filter screen 200 exposed outside the ribs is adjacent to the connecting portion 1026 .
[0059] It can be understood that the wall thickness of the connecting portion 1026 is less than the wall thickness of the supporting portion 1025, so that the width difference is formed in different areas of the cross section of the glue passage used for injection molding the corrugated structure 1024 in the injection mold. Specifically, in the mold used to mold the frame 101 of the present application, the flow passage at least includes a guide space for molding the supporting portion 1025 and a retention space for molding the connecting portion 1026, and accordingly, the cross-sectional height of the guide space is greater than the cross-sectional height of the retention space, that is, the retention space is narrower than the guide space in the height direction of the flow passage. In this way, the injection molded When the frame 101 is formed, during the process of plastic filling through the glue channel, there will be characteristics such as small flow resistance and long flow length in the guide space, and large flow resistance and short flow length in the retention space. In this way, the guide space ensures that the frame 101 is filled with low pressure and high speed. Since the part of the corrugated filter 200 outside the corrugated structure 1024 is adjacent to the retention part, the retention space is used to ensure that the edge area where the frame 101 and the corrugated filter 200 are combined is filled with low temperature and low speed. By utilizing the filling advantage of low temperature and low speed in the retention space, the gap of overflow glue can be greatly widened, thereby protecting the mesh material and reducing the chance of mesh breakage.
[0060] See also Figure 3 and Figure 5 In some embodiments, connecting portions 1026 are provided on both sides of the supporting portion 1025 of the corrugated structure 1024 of the third connecting rib 1023 , and the supporting portion 1025 and the connecting portions 1026 on both sides are connected to the corrugated filter 200 .
[0061] It can be understood that the third connecting rib 1023 can be multiple, and the multiple third connecting ribs 1023 are arranged at intervals and are located between the first connecting rib 1021 and the second connecting rib 1022. For example, the corrugated filter 200 is integrated with the corrugated structure 1024 through the injection molding process. Therefore, the corrugated filter 200 passes through the support portion 1025 of each third connecting rib 1023 and the connecting portions 1026 on both sides, and the contact parts of the two are fastened by injection molding. In other words, when the injection molding process is used to form the grid 100, the fluid material will fill the mesh gap of the corrugated filter 200 at the location where the corrugated filter 200 is connected to the third connecting rib 1023, so that after molding, the corrugated filter 200 presents a structure in which the corrugated filter 200 passes through the support portion 1025 of the third connecting rib 1023 and the connecting portions 1026 on both sides.
[0062] See also Figure 1 , Figure 3 and Figure 5 In some embodiments, the grid 100 includes a frame 101 , and the connecting ribs 102 are disposed in the area enclosed by the frame 101 .
[0063] It can be understood that the grid 100 can be in the shape of a square frame 101, a rectangular frame 101 or a conventional frame 101 in the art, and the present application is not limited thereto. Exemplarily, the grid 100 is a rectangular frame 101, and the rectangular frame 101 has a first side and a second side that are relatively arranged, wherein the first side and the second side can be sides along the length direction of the rectangular frame 101, or can be sides along the width direction of the rectangular frame 101, and the connecting rib 102 is located between the first side and the second side, and there are multiple connecting ribs 102 and they are arranged at intervals, and further, the connecting rib 102 can also be located on the side of the first side close to the second side, and further, the connecting rib 102 can also be located on the side of the second side close to the first side.
[0064] See also Figure 1 and Figure 3 In some embodiments, the frame 101 includes a first frame 1011 and a second frame 1012 relative to each other, and the extension directions of the first frame 1011 and the second frame 1012 are parallel to the extension direction of the connecting rib 102, and the connecting rib 102 includes a first connecting rib 1021 and a second connecting rib 1022 arranged at intervals, and the first connecting rib 1021 and the second connecting rib 1022 both have a corrugated structure 1024, the first connecting rib 1021 is arranged on a side of the first frame 1011 facing the second frame 1012, and is connected to the first frame 1011, and the second connecting rib 1022 is arranged on a side of the second frame 1012 facing the first frame 1011, and is connected to the second frame 1012.
[0065] It can be understood that the frame 101 can be a regular square frame, the square frame has a first direction, the first direction can be any direction on the four sides of the square frame, the square frame also has a second direction, the first direction and the second direction are perpendicular to each other, the first frame 1011 and the second frame 1012 can be set along the first direction, and the first frame 1011 and the second frame 1012 can also be set along the second direction.
[0066] It can be understood that the corrugated structure 1024 of the first connecting rib 1021 and the corrugated structure 1024 of the second connecting rib 1022 are arranged relative to each other, so that the corrugated filter 200 can be respectively adapted to the corrugated structure 1024 of the first connecting rib 1021 and the corrugated structure 1024 of the second connecting rib 1022 (that is, different parts of the corrugated filter 200 are respectively connected to the corrugated structure 1024 of the first connecting rib 1021 and the corrugated structure 1024 of the second connecting rib 1022), and at the same time, the two ends of the corrugated filter 200 along the direction from the first connecting rib 1021 to the second connecting rib 1022 can be respectively fixed to the corresponding inner side of the frame 101, and the fixing method can be hot melt connection, bonding or clamping.
[0067] It can be understood that the connection method between the first connecting rib 1021 and the first frame 1011 and the connection method between the second connecting rib 1022 and the second frame 1012 can be hot-melt connection, bonding or clamping.
[0068] See also Figure 3 and Figure 5 In some embodiments, the connecting rib 102 further includes a third connecting rib 1023, which is disposed between the first connecting rib 1021 and the second connecting rib 1022, and has a corrugated structure 1024. The corrugated structures 1024 of the first connecting rib 1021, the second connecting rib 1022, and the third connecting rib 1023 may be disposed in the same plane, that is, along the direction from the first connecting rib 1021 to the second connecting rib 1022, in the same projection plane, the contour lines of the projections of the corrugated structures 1024 of the three coincide.
[0069] It is understandable that the third connecting rib 1023 can be one or more. When there are more than one third connecting rib 1023, the third connecting ribs 1023 are arranged between the first connecting rib 1021 and the second connecting rib 1022 at intervals, so that the frame 101 is supported and stabilized, and the corrugated filter screen 200 is supported and tensioned to prevent the corrugated filter screen 200 from collapsing.
[0070] It can be understood that during installation, the corrugated filter screen 200 is matched with the corrugated structure 1024 of the third connecting rib 1023 and fixed on the corrugated structure 1024 of the third connecting rib 1023, and the fixing method can be hot-melt connection, bonding or clamping. Preferably, during the mold injection molding process, the corrugated filter screen 200 is adhered to the mold and is injection molded together with the third connecting rib 1023.

[0072] It can be understood that the extension direction of the reinforcing plate 1013 is parallel to the extension direction of the connecting rib 102. At the same time, the width of the reinforcing plate 1013 perpendicular to the extension direction is greater than the width of the connecting rib 102 perpendicular to the extension direction. In this way, the corrugated filter 200 can be prevented from collapsing in the middle due to excessive span under the influence of gravity.
[0073] It can be understood that the first connecting rib 1021 and the second connecting rib 1022 on both sides of the reinforcing plate 1013 can be directly fixed on both sides of the reinforcing plate 1013, or the connecting plates can be pre-fixed on both sides of the reinforcing plate 1013, and then the first connecting rib 1021 and the second connecting rib 1022 are fixed to the side of the connecting plate away from the reinforcing plate 1013, wherein the fixing method can be hot-melt connection, bonding or clamping. Preferably, when connecting plates are provided on both sides of the reinforcing plate 1013, the reinforcing plate 1013 and the connecting plates on both sides form an air-avoiding groove, which is convenient for matching with the components in the air conditioner indoor unit.
[0074] See also Figure 1 , Figure 3 and Figure 5 In some embodiments, the grid 100 further includes reinforcing ribs 103 connected to the connecting ribs 102 , and an extension direction of the reinforcing ribs 103 intersects with an extension direction of the corrugated structure 1024 .

When there are multiple reinforcing ribs 103, each reinforcing rib 103 is arranged in parallel, and the extension direction of each reinforcing rib 103 intersects with the extension direction of the corrugated structure 1024. Preferably, the extension direction of each reinforcing rib 103 is orthogonal to the extension direction of the corrugated structure 1024.
[0076] It can be understood that the four corners of the grid 100 are configured to be rounded to protect the internal structure of the air conditioner and reduce the danger to the user.
[0077] See also Figure 6 and Figure 7 An embodiment of the present application provides an air conditioner, comprising: a shell 300 , on which an air inlet 301 is arranged; and the aforementioned filter, which is detachably connected to the shell 300 and is located at the air inlet 301 .
[0078] It can be understood that the frame 100 has a third side and a fourth side that are relatively arranged, a buckle 104 is provided on the side of the third side away from the fourth side, and a buckle 105 is provided on the fourth side away from the third side.

The buckle 104 is provided in the slot, and the buckle 105 is provided on the clamping rib. In this way, it is easy to disassemble and install, and the operation is convenient.
