[0050] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0051] like Figures 1-15 As shown, an embodiment of the present application provides an air conditioner indoor unit, wherein the air conditioner indoor unit can be a cabinet unit, which can be placed on the ground; or, the air conditioner indoor unit can be hung vertically on a wall.

[0052] The indoor unit of the air conditioner comprises: a shell assembly, a heat exchanger bracket 2 and a filter 3.

[0053] The housing assembly may include a first housing 1, an air inlet 14 being provided on the first housing 1, and a first guide groove 15 being provided on the inner wall surface of the first housing 1. The first housing 1 may be a rear box located at the rear side, and the air inlet 14 and the first guide groove 15 may be provided on the rear box.

[0054] The heat exchanger bracket 2 is installed within the housing assembly and can be used to secure the heat exchanger 5 (which can serve as an evaporator). The heat exchanger 5 can be secured to the side of the heat exchanger bracket 2 away from the air inlet 14. A second guide groove 21 is provided on the side of the heat exchanger bracket 2 facing the first housing 1. The second guide groove 21 and the first guide groove 15 are sequentially arranged along the extension direction of the second guide groove 21 and are in communication.

[0055] The filter 3 is configured to be slidably assembled in the second guide groove 21 and the first guide groove 15 along the extending direction of the second guide groove 21 and cover the air inlet 14 .

[0056] In the indoor unit of the air conditioner according to the embodiment of the present application, the filter 3 can be arranged vertically, and the installation position of the filter 3 is between the first shell 1 (rear box) and the heat exchanger bracket 2. A first guide groove 15 is provided on the inner wall surface of the first shell 1 facing the heat exchanger bracket 2, and a second guide groove 21 is provided on the side of the heat exchanger bracket 2 facing the first shell 1. The second guide groove 21 and the first guide groove 15 are connected, so that when the filter 3 is slidably installed between the first shell 1 and the heat exchanger bracket 2, the edge of the filter 3 can slide along the second guide groove 21 and the first guide groove 15 in sequence; when the filter 3 is installed in place and covers the air inlet 14, a portion of the edge of the filter 3 is located in the second guide groove 21, and the other portion of the edge of the filter 3 is located in the first guide groove 15, so that the filter 3 is limited by the first guide groove 15 and the second guide groove 21, ensuring that the filter 3 can effectively filter the air entering the air inlet 14.

[0057] In this air conditioner indoor unit, a portion of the complete guide groove for positioning the filter 3 (i.e., the second guide groove 21) is provided on the heat exchanger support 2, and a portion (i.e., the first guide groove 15) is provided on the first housing 1. Therefore, the complete guide groove for positioning the filter 3 is formed by combining the second guide groove 21 on the heat exchanger support 2 and the first guide groove 15 on the first housing 1. Compared to a guide groove for positioning the filter 3 provided only on the heat exchanger support 2, the guide groove for positioning the filter 3 in the embodiment of the present application is formed by combining the second guide groove 21 and the first guide groove 15, which helps increase the area of the filter 3, thereby increasing the air inlet area and improving the air volume of the entire unit.

[0058] In some exemplary embodiments, Figure 5-Figure 6 、 Figure 11-12 、 Figure 15 As shown, the first shell 1 includes a first shell wall 11, a second shell wall 12 and a third shell wall 13 connected in sequence in a U shape, the first shell wall 11 and the second shell wall 12 are provided with an air inlet 14, the filter 3 is L-shaped, and the first guide groove 15 is provided at the connecting portion 131 between the second shell wall 12 and the third shell wall 13.

[0059] The first housing 1 has a first wall 11 and a third wall 13 disposed opposite each other, and may serve as the left and right walls of the rear housing, respectively. The second wall 12 is located between the first wall 11 and the second wall 12 and may serve as the rear wall of the rear housing. Air inlets 14 may be provided on the left and rear walls of the rear housing. Accordingly, the filter 3 is L-shaped to filter air entering through the air inlets 14 on the left and rear walls of the rear housing.

[0060] A connection portion 131 is defined between the rear and right walls of the rear housing. This connection portion 131 can be a smooth connection portion 131 (e.g., an arcuate shape). The first guide groove 15 can be disposed at the connection portion 131 between the rear and right walls of the rear housing. The first guide groove 15 guides the filter 3 from the second guide groove 21 of the heat exchanger support 2 into the first guide groove 15 of the rear housing, allowing the filter 3 to extend to the connection portion 131 between the rear and right walls of the rear housing, thereby increasing the area of the filter 3.

[0061] In order to adapt to the increased area of the filter 3, in some exemplary embodiments, such as Figure 1-Figure 2 、 Figure 5-Figure 6 ,like Figure 11-12 As shown, an air inlet 14 is provided at the connection portion 131 between the second shell wall 12 and the third shell wall 13 of the first shell 1 , that is, an air inlet 14 is provided at the connection portion 131 between the rear shell wall and the right shell wall of the rear box body.

[0062] Specifically, not only can an air inlet 14 be provided on the left shell wall and the rear shell wall of the rear box body, but an air inlet 14 can also be provided at the connection portion 131 between the rear shell wall and the right shell wall of the rear box body, so that the area of the air inlet 14 is increased; the L-shaped filter 3 extending to the connection portion 131 between the rear shell wall and the right shell wall of the rear box body can not only cover the air inlet 14 provided on the left shell wall and the rear shell wall of the rear box body, but also cover the air inlet 14 provided at the connection portion 131 between the rear shell wall and the right shell wall of the rear box body, so as to effectively filter the air entering through the air inlet 14.

[0063] In the indoor unit of the air conditioner according to the embodiment of the present application, the area of the air inlet 14 and the area of the filter 3 are both increased, which is beneficial to improving the air volume of the entire unit.

[0064] It should be understood that the area of the air inlet region where the air inlet 14 is located is not larger than the area of the filter 3 (e.g., smaller than the area of the filter 3), so that the filter 3 can fully and effectively filter the air entering the air inlet 14. Figure 5-Figure 6 As shown, the air inlet 14 is arranged at the connection portion 131 between the rear shell wall and the right shell wall of the rear box body, and the right edge of the area where it is located needs to be on the left side of the right edge of the filter 3.

[0065] In some exemplary embodiments, Figure 1-Figure 2 、 Figure 5-Figure 6 ,like Figure 11-12 As shown, the air inlet 14 of the first shell wall 11 of the first housing 1 is a square opening, and the air inlet grille 4 is installed at the square opening. The filter 3 can be assembled from the square opening and slide into the second guide groove 21 and the first guide groove 15 in sequence.

[0066] In some exemplary embodiments, the filter screen 3 is provided with a bent portion 33 at one end (eg, the right end) close to the first guide groove 15 and bent toward a side away from the second shell wall 12. Figure 4 、 Figure 6 and Figure 15 As shown, the right end of the filter screen 3 is provided with a slightly curved bending portion 33, which can match the connecting portion 131 between the rear shell wall and the right shell wall of the rear box body and the first guide groove 15 thereon.

[0067] In some exemplary embodiments, Figure 4 and Figure 14 As shown, the second guide groove 21 includes a first groove wall 211, a second groove wall 212, and a third groove wall 213, which are sequentially connected in a U-shape. The first groove wall 211 is located on the side of the second groove wall 212 that is closer to the first housing 1. The first groove wall 211 and the third groove wall 213 of the second guide groove 21 can be vertically arranged as the rear groove wall and the front groove wall, respectively. The second groove wall 212 can be a horizontally arranged upper groove wall, so that the opening of the U-shaped second guide groove 21 faces downward, allowing the upper edge of the filter screen 3 to extend into the second guide groove 21. Alternatively, the second guide groove 21 can be a horizontally arranged lower groove wall, so that the opening of the U-shaped second guide groove 21 faces upward, allowing the lower edge of the filter screen 3 to extend into the second guide groove 21. The first groove wall 211 and the third groove wall 213 of the second guide groove 21 can form opposite side walls of the second guide groove 21, and the second groove wall 212 can form the bottom wall of the second guide groove 21.

[0068] like Figure 10 、 Figure 12 and Figure 14 As shown, the first groove wall 211 includes a first end face 214 close to one end of the first guide groove 15, the second groove wall 212 includes a second end face 215 close to one end of the first guide groove 15, and the second groove wall 212 also includes a third end face 216 facing the inner side of the second guide groove 21; the first guide groove 15 includes a fourth end face 154, a fifth end face 155 and a sixth end face 156, the fourth end face 154 abuts the first end face 214, the fifth end face 155 abuts the second end face 215, and the sixth end face 156 faces the inner side of the first guide groove 15 and extends along the extension direction of the second guide groove 21, and the sixth end face 156 is coplanar with the third end face 216.

[0069] Specifically, in the second guide groove 21, the first end surface 214 and the second end surface 215 can be the right end surfaces of the first groove wall 211 and the second groove wall 212, respectively, and the third end surface 216 can be the inward-facing upper end surface or lower end surface of the third groove wall 213. In the first guide groove 15, the fourth end surface 154 and the fifth end surface 155 can be the end surfaces on the left side of the first guide groove 15, and the sixth end surface 156 can be the upper end surface or lower end surface inside the first guide groove 15. After the heat exchanger bracket 2 is assembled into the shell, the fourth end surface 154 of the first guide groove 15 abuts the first end surface 214 of the second guide groove 21, the fifth end surface 155 of the first guide groove 15 abuts the second end surface 215 of the second guide groove 21, and the sixth end surface 156 of the first guide groove 15 is coplanar with the third end surface 216 of the second guide groove 21, thereby achieving the splicing of the first guide groove 15 and the second guide groove 21 to form a complete guide groove for limiting the filter screen 3. After the left end of the first guide groove 15 and the right end of the second guide groove 21 abut (the adjacent ends of the first guide groove 15 and the second guide groove 21 abut), the first guide groove 15 and the second guide groove 21 are connected, so that the filter screen 3 can slide from the second guide groove 21 into the first guide groove 15, so that the edge of the filter screen 3 is limited in the first guide groove 15 and the second guide groove 21.

[0070] It should be understood that the sixth end face 156 of the first guide groove 15 can be set to be coplanar with the third end face 216 of the second guide groove 21, or the sixth end face 156 of the first guide groove 15 can be set to be recessed relative to the third end face 216 of the second guide groove 21, so that when the filter screen 3 slides from the second guide groove 21 into the first guide groove 15, the sixth end face 156 of the first guide groove 15 can avoid the filter screen 3 and will not block the filter screen 3 from sliding into the first guide groove 15.

[0071] In some exemplary embodiments, one of the first end surface 214 and the second end surface 215 of the second guide groove 21 is more convex than the other toward the side where the first guide groove 15 is located. Figure 10 、 Figure 12 and Figure 14 As shown, the second end face 215 of the second guide groove 21 protrudes toward the side where the first guide groove 15 is located compared to the first end face 214, that is, the second end face 215 protrudes toward the right side compared to the first end face 214; accordingly, the fourth end face 154 of the first guide groove 15 protrudes toward the side where the second guide groove 21 is located compared to the fifth end face 155, that is, the fourth end face 154 protrudes toward the left side compared to the fifth end face 155, so that the fourth end face 154 of the first guide groove 15 can abut against the first end face 214 of the second guide groove 21, and the fifth end face 155 of the first guide groove 15 can abut against the second end face 215 of the second guide groove 21, so as to realize the overlap of the first guide groove 15 and the second guide groove 21, and then assemble to form a complete guide groove for limiting the filter screen 3.

[0072] In some other exemplary embodiments, Figure 16 and Figure 17 As shown, the first end face 214 of the second guide groove 21 is flush with the second end face 215, and correspondingly, the fourth end face 154 of the first guide groove 15 is flush with the fifth end face 155, so that the fourth end face 154 of the first guide groove 15 can abut against the first end face 214 of the second guide groove 21, and the fifth end face 155 of the first guide groove 15 can abut against the second end face 215 of the second guide groove 21, so as to realize the splicing of the first guide groove 15 and the second guide groove 21, thereby forming a complete guide groove for limiting the filter screen 3.

[0073] In some exemplary embodiments, Figure 6 、 Figure 10 and Figure 12 As shown, the first guide groove 15 includes a fourth groove wall 151, which is located on a side close to the second guide groove 21 (e.g., the left side) and extends along the width direction (e.g., the up and down direction) of the filter 3, and the end surface of the fourth groove wall 151 facing the outside of the first guide groove 15 forms a fourth end surface 154, and the end surface of the fourth groove wall 151 facing away from the inner wall surface of the first shell 1 (e.g., the front side) forms a support limit surface 157, and the filter 3 is supported on the side facing the first shell 1 (e.g., the rear side) on the support limit surface 157.

[0074] Specifically, the fourth groove wall 151 is located on the left side of the first guide groove 15 and can extend in the up and down directions, and the left end surface of the fourth groove wall 151 facing the outside of the first guide groove 15 can form a fourth end surface 154, so that the fourth end surface 154 abuts against the first end surface 214 on the right side of the first groove wall 211 of the second guide groove 21, so that the first shell 1 can support and limit the heat exchanger bracket 2; the front end surface of the fourth groove wall 151 facing away from the inner wall surface of the first shell 1 can form a support and limit surface 157, and the filter screen 3 can be supported on the support and limit surface 157 toward the rear side of the first shell 1, so that the filter screen 3 can be limited in the front and rear directions (thickness direction of the filter screen 3) by the support and limit surface 157.

[0075] In some exemplary embodiments, Figure 6 、 Figure 10 and Figure 12 As shown, the first guide groove 15 also includes a fifth groove wall 152, which is located on the side of the fourth groove wall 151 away from the second guide groove 21 (e.g., the right side), and extends along the extension direction of the second guide groove 21. The end surface of the fifth groove wall 152 facing the side of the second guide groove 21 (e.g., the left side) forms a fifth end surface 155, and the end surface of the fifth groove wall 152 facing the inner side of the first guide groove 15 forms a sixth end surface 156.

[0076] Specifically, the fifth groove wall 152 can be located on the right side of the fourth groove wall 151 and can extend in the left-right direction, and the left end surface of the fifth groove wall 152 facing the second guide groove 21 can form a fifth end surface 155, and the fifth end surface 155 abuts the first end surface 214 on the right side of the second groove wall 212 of the second guide groove 21; the upper end surface or lower end surface of the fifth groove wall 152 facing the inner side of the first guide groove 15 can form a sixth end surface 156, and the sixth end surface 156 can be coplanar with the third end surface 216 of the second guide groove 21, and the upper side surface or lower side surface of the vertically arranged filter screen 3 can abut with the coplanar sixth end surface 156 and the third end surface 216, so as to support and limit the filter screen 3 in the up and down directions.

[0077] In some exemplary embodiments, Figure 12 As shown, the first guide groove 15 also includes a support rib 158, which is located on the side of the fourth groove wall 151 away from the second guide groove 21 (such as the right side) and extends along the extension direction of the second guide groove 21. The filter 3 is supported on the support rib 158 on the side facing the first shell 1.

[0078] Specifically, the support rib 158 can be located on the right side of the fourth slot wall 151 and can extend in the left-right direction. The filter 3 can be supported on the support rib 158 toward the rear side of the first shell 1 so that the filter 3 can be limited in the front-back direction by the support rib 158.

[0079] In some exemplary embodiments, the first guide groove 15 further includes a limiting portion (not shown), which is located on the side of the filter 3 facing away from the first shell 1 (such as the front side) and is configured to limit the side of the filter 3 facing away from the first shell 1.
