[0045] Embodiment one:

[0046] Figure 1 A structural schematic view of the filter screen device provided by the embodiment one of the present application is shown in the figure. Figure 2 A top view of the filter screen device provided by the embodiment one of the present application is shown in the figure. Figure 1 And Figure 2 As shown in the figures, the filter screen device 100 provided by the embodiment one of the present application comprises a filter screen support 110 and a filter screen body 190 fixedly connected to the lower part of the filter screen support 110. The filter screen support 110 comprises a first lower recess assembly 111 and a second lower recess assembly 112. The first lower recess assembly 111 is located at the front of the filter screen support 110, the bottom of the first lower recess assembly 111 is lower than the bottom of the second lower recess assembly 112, the second lower recess assembly 112 is located behind the first lower recess assembly 111 and adjacent to the first lower recess assembly 111, and the lower part of the first lower recess assembly 111 and the lower part of the second lower recess assembly 112 are both fixedly connected to the filter screen body 190.

[0047] By arranging the second lower recess assembly 112 in the filter screen support 110, the second lower recess assembly 112 is adjacent to the first lower recess assembly 111, and the lower part of the first lower recess assembly 111 and the lower part of the second lower recess assembly 112 are both fixedly connected to the filter screen body 190, so that the area of the filter screen body 190 can be increased. In the case of the same air intake amount, the area of the filter screen body 190 is larger, and the number of holes of the filter screen is more, which not only helps to reduce the air inlet resistance, but also helps to reduce the dust accumulation speed on the filter screen body 190, increase the time interval of cleaning the filter screen, and improve the user experience.

[0048] In the embodiment, the front fold part of the indoor heat exchanger of the wall-mounted air conditioner indoor unit is located closer to the front surface of the wall-mounted air conditioner indoor unit in the substantially inverted triangular space formed by the top surface and the front surface of the wall-mounted air conditioner indoor unit. Therefore, the bottom of the first lower recess assembly 111 is lower than the bottom of the second lower recess assembly 112, thereby improving the space utilization and increasing the area of the filter screen body 190.

[0049] In the embodiment, the first lower recess assembly 111 includes a first lower recess 121 and a third lower recess 123, and the second lower recess assembly 112 includes a second lower recess 122 and a fourth lower recess 124.

[0050] Figure 3 A bottom view of the filter screen device according to the first embodiment of the present application is provided. Figure 4 A front view of the filter screen device according to the first embodiment of the present application is provided. Figure 5 A rear view of the filter screen device according to the first embodiment of the present application is provided. Figure 6 A left view of the filter screen device according to the first embodiment of the present application is provided. Figure 7 A sectional view of the filter screen device according to the first embodiment of the present application is provided. Figures 1-7 As shown in the figure, the filter screen support 110 includes middle support strips 113 and side support strips 114 arranged at intervals, the side support strips 114 are located at both ends of the filter screen support 110 in the left-right direction, and the middle support strips 113 are located between the side support strips 114; the middle support strips 113 have a first lower recess 121 and a second lower recess 122, the bottom of the first lower recess 121 is lower than the bottom of the second lower recess 122, the first lower recess 121 is adjacent to the second lower recess 122, and the lower parts of the first lower recess 121 and the second lower recess 122 are fixedly connected to the filter screen body 190.

[0051] By arranging the middle support strips 113 and arranging the first lower recess 121 and the second lower recess 122 on the middle support strips 113, the first lower recess 121 and the second lower recess 122 can be used to support most of the space of the filter screen body 190 in the left-right direction, thereby forming a shape with multiple lower recess regions, thereby facilitating the increase of the area of the filter screen body 190.

[0052] Specifically, in the embodiment, the number of the middle support strips 113 is three, and the middle support strips 113 are arranged along the left-right direction of the filter screen body 190. Each middle support strip 113 is arranged corresponding to a support beam 210 of a middle frame 200 of the wall-mounted air conditioner indoor unit, wherein the position of the middle support strip 113 corresponds to the position of the support beam 210, and preferably, the width of the middle support strip 113 is less than or equal to the width of the support beam 210, that is, the middle support strip 113 is completely located in the area of the support beam 210 in the vertical direction.

[0053] As Figures 1-7 shown, optionally, the side support bar 114 comprises a third lower recess 123 and a fourth lower recess 124, the bottom of the third lower recess 123 is lower than the bottom of the fourth lower recess 124, and the third lower recess 123 is adjacent to the fourth lower recess 124, and the lower part of the third lower recess 123 and the fourth lower recess 124 are fixedly connected with the filter screen body 190.

[0054] By arranging the third lower recess 123 and the fourth lower recess 124 on the side support bar 114, the left and right ends of the filter screen body 190 can be supported to form a shape with multiple lower recessed areas, thereby facilitating the increase of the area of the filter screen body 190.

[0055] Among them, the third lower recess 123 and the first lower recess 121 are recessed in the same shape and depth, and the fourth lower recess 124 and the second lower recess 122 are recessed in the same shape and depth. Thus, the cross section of the filter screen body 190 is basically the same at different positions in the left-right direction.

[0056] Figure 8 A three-dimensional sectional view of the filter screen device provided by the first embodiment of the present application is applied to a wall-mounted indoor unit of an air conditioner; Figure 9 A structure diagram of a wall-mounted indoor unit of an air conditioner according to the second embodiment of the present application is shown in the figure. Figures 1-5 And Figures 7-9 As shown, optionally, the first horizontal connecting rod 131 is arranged between adjacent second lower recesses 122 and between the adjacent second lower recess 122 and the fourth lower recess 124.

[0057] By arranging the first horizontal connecting rod 131, each second lower recess 122 and fourth lower recess 124 can be supported horizontally, so that the load borne by a single second lower recess 122 and fourth lower recess 124 is shared by each second lower recess 122 and fourth lower recess 124, thereby using multiple second lower recesses 122 and fourth lower recesses 124 to bear the load together, improving the rigidity and reducing the deformation.

[0058] Compared with the original scheme of arranging support plates on both sides of the support beam 210, that is, the filter screen and its connecting structure between adjacent support beams 210 are independent, the first horizontal connecting rod 131 can be used to form a whole support structure, which significantly improves the rigidity of the filter screen support 110.

[0059] In addition, between each adjacent first lower recess 121, and between the adjacent first lower recess 121 and the third lower recess 123, a third horizontal connecting rod 133 can also be arranged to support each first lower recess 121 and the third lower recess 123. In the embodiment, the first horizontal connecting rod 131 and the third horizontal connecting rod 133 are also fixedly connected with the filter screen body 190.

[0060] As shown in Figures 1-3 and Figures 6-8 Optionally, a first upper protrusion 125 is arranged between the first lower recess 121 and the second lower recess 122 of the same middle support bar 113, and a second upper protrusion 126 is arranged between the third lower recess 123 and the fourth lower recess 124 of the same side support bar 114; between each adjacent first upper protrusion 125, and between each adjacent first upper protrusion 125 and the second upper protrusion 126, a second horizontal connecting rod 132 is arranged.

[0061] By arranging the second horizontal connecting rod 132, each first upper protrusion 125 and each second upper protrusion 126 can be transversely supported, so that the load borne by a single first upper protrusion 125 can be shared by each second upper protrusion 126, thereby improving the rigidity of the filter screen support 110 and reducing the deformation of the filter screen support 110.

[0062] In the embodiment, the second horizontal connecting rod 132 is also fixedly connected with the filter screen body 190.

[0063] As shown in Figures 1-3 and Figures 5-8 Optionally, a first support rib plate 141 is arranged on the lower side of the first upper protrusion 125; and / or a second support rib plate 142 is arranged on the lower side of the second upper protrusion 126.

[0064] In this way, the first support rib plate 141 and the second support rib plate 142 can be used to support the lower part of the first upper protrusion 125 and the lower part of the second upper protrusion 126, preventing the local support bars of the first upper protrusion 125 and the second upper protrusion 126 from approaching each other, thereby facilitating the middle support bar 113 and the side support bar 114 to maintain their shapes, so as to ensure that the filter screen body 190 has sufficient filtering area.

[0065] In the embodiment, the support range of the first support rib plate 141 for the first upper convex part 125 is greater than the support range of the second support rib plate 142 for the second upper convex part 126. Because the second upper convex part 126 is closer to the frame 151 described below, and the third lower concave part 123 and the fourth lower concave part 124 are respectively supported by the fifth support rib plate 145 and the sixth support rib plate 146, and the upper parts of the fifth support rib plate 145 and the sixth support rib plate 146 are connected to the frame 151, the second upper convex part 126 has a strong limiting ability, so the second upper convex part 126 does not need a large support range. For the first upper convex part 125, because the upper part of the third support rib plate 143 on the side of the first lower concave part 121 and the upper part of the fourth support rib plate on the side of the second lower concave part 122 do not extend to the frame 151, the first upper convex part 125 can be supported in a larger length range.

[0066] As shown in Figure 1 , Figure 2 and Figure 7 , Figure 8 , optionally, the first lower concave part 121 is provided with a third support rib plate 143, and the third support rib plate 143 extends upward from the two side walls of the first lower concave part 121.

[0067] In this way, the first lower concave part 121 is supported by the third support rib plate 143, so that the rigidity of the middle support bar 113 in the local part of the first lower concave part 121 can be improved, and the middle support bar 113 can maintain the original shape, so as to ensure that the filter screen body 190 has sufficient filtering area.

[0068] In the embodiment, the third support rib plate 143 can be in the shape of a support ridge. Specifically, the first lower concave part 121 is approximately V-shaped, and the third support rib plate 143 is also a V-shaped plate or a ridge extending along the V shape. The ratio of the height to the width of the ridge can be 1.5:1 to 5:1.

[0069] As shown in Figure 1 , Figure 2 and Figure 7 , Figure 8 , optionally, the upper side of the second lower concave part 122 is provided with a fourth support rib plate 144, and the height of the fourth support rib plate 144 is consistent with the top of the two side walls of the second lower concave part 122.

[0070] The fourth support rib plate 144 is arranged in this way, so that the rigidity of the middle support strip 113 in the second lower recess 122 is improved, and the middle support strip 113 is kept in the original shape, so that the filter screen body 190 has sufficient filtering area. Moreover, since the second lower recess 122 is located on the side of the first lower recess 121 away from the middle frame 200, the air flow speed is fast, and the dust accumulation speed is faster than that of the first lower recess 121. The fourth support rib plate 144 arranged in this way can play a blocking role in the left-right direction, and can prevent the dust accumulated in the second lower recess 122 from spreading from the left and right sides.

[0071] As shown in Figures 1-3 and Figure 6 、 Figure 7 The filter screen support 110 can optionally include a frame 151, the third lower recess 123 is provided with a fifth support rib plate 145, and the fourth lower recess 124 is provided with a sixth support rib plate 146; the fifth support rib plate 145 and the sixth support rib plate 146 are connected with the frame 151.

[0072] In this way, when the filter screen device 100 is taken out from the air conditioner, the dust on the filter screen body 190 can be prevented from sliding from the side of the filter screen device 100 to the inside of the air conditioner and accumulating on the indoor heat exchanger, thereby facilitating the efficient operation of the air conditioner indoor unit. In addition, the rigidity of the third lower recess 123 and the fourth lower recess 124 can be improved, and the side support strip 114 can be kept in the original shape, so that the filter screen body 190 has sufficient filtering area.

[0073] Specifically, in the embodiment, the fifth support rib plate 145 extends from the upper surface of the third lower recess 123 to the lower surface of the frame 151, and the sixth support rib plate 146 extends from the upper surface of the fourth lower recess 124 to the lower surface of the frame 151, so as to block the positions of the two ends of the filter screen body 190 in the left-right direction.
