DETAILED DESCRIPTION

[0055] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0056] like Figure 1-Figure 26 As shown, an embodiment of the present application provides an indoor unit of an air conditioner, including a surface frame 1 and a filter 2.

[0057] The face frame 1 is provided with an air inlet 10 (see Fig.18 ) and a first sliding part, the filter screen 2 is provided with a second sliding part, and the second sliding part can be slidably matched with the first sliding part to slide the filter screen 2 to the face frame 1. Wherein, the indoor unit of the air conditioner can be a wall mounted unit, and the air inlet 10 and the first sliding part can be arranged on the top wall of the face frame 1.

[0058] like Figure 2 and Figure 3As shown, one of the first sliding part and the second sliding part includes a slide groove 11, and the other includes a slide rail 21. An insertion opening 110 is provided at one end of the slide groove 11. The slide groove 11 includes a first side wall 111 extending in the length direction. The first side wall 111 of the slide groove 11 is provided with an opening 118 penetrating the first side wall 111 in the wall thickness direction. The slide rail 21 is configured to slide into the slide groove 11 from the insertion opening 110, and the slide rail 21 passes through the opening 118, so that the filter 2 is slidably installed on the face frame 1 and covers the air inlet 10. The portion of the slide rail 21 that slides into the slide groove 11 includes a first stop protrusion 211 (see Figure 3 and Fig.26 ).

[0059] The first sliding part may include a slide groove 11, and the second sliding part may include a slide rail 21, that is, the face frame 1 may be provided with a slide groove 11, and the filter screen 2 may be provided with a slide rail 21. Of course, the first sliding part may also include a slide rail 21, and the second sliding part may also include a slide groove 11, that is, the face frame 1 may also be provided with a slide rail 21, and the filter screen 2 may also be provided with a slide groove 11.

[0060] When the filter 2 is slidably mounted to the face frame 1, a portion of the slide rail 21 can be inserted from the insertion port 110 of the slide slot 11 and gradually slide into the slide slot 11; at the same time, another portion of the slide rail 21 can pass through the opening 118 of the first side wall 111 of the slide slot 11, so that the portion of the slide rail 21 that passes through the opening 118 is connected to the filter 2 located outside the slide slot 11, and while a portion of the slide rail 21 slides into the slide slot 11, another portion of the slide rail 21 slides along the opening 118. When the slide rail 21 slides into place, the filter 2 is installed in place, and at this time, the filter 2 can cover the air inlet 10 of the face frame 1, so that the filter 2 can filter the air entering from the air inlet 10. The slide rail 21 can also slide out from the insertion port 110 to achieve the removal of the filter 2 from the face frame 1.

[0061] The portion of the slide rail 21 that slides into the slide groove 11 includes a first stop protrusion 211, and the cross-sectional area of ​​the first stop protrusion 211 can be larger than the cross-sectional area of ​​the opening 118 to prevent the slide rail 21 from escaping from the opening 118, thereby ensuring the reliability of the sliding fit between the slide rail 21 and the slide groove 11, thereby ensuring the installation reliability of the filter 2 and the effective filtration of the air.

[0062] In the indoor unit of the air conditioner in the embodiment of the present application, the filter 2 is installed to the top wall of the face frame 1 by sliding cooperation. Compared with the technical solutions in the prior art that the filter can only be removed by opening the panel or the filter is fixed by snaps, in the indoor unit of the air conditioner in the embodiment of the present application, the filter 2 can be disassembled and assembled by sliding without opening the panel. On the one hand, the disassembly of the filter 2 is improved, and on the other hand, the assembly efficiency of the filter 2 is improved, thereby improving the user experience.

[0063] In some exemplary embodiments, Fig.18 As shown, two first sliding parts are provided and are respectively located at opposite sides of the air inlet 10 , such as: the two first sliding parts can be respectively located at the left and right sides of the air inlet 10 , and the two first sliding parts can extend along the front-rear direction.

[0064] Accordingly, if Figure 1 As shown, there are two second sliding parts, which are respectively located on opposite sides of the filter 2, such as: the two second sliding parts can be respectively located on the left and right sides of the filter 2, and the two second sliding parts can extend in the front-back direction. The two second sliding parts can respectively slide with the two first sliding parts.

[0065] The first sliding part on the face frame 1 may include a slide groove 11, and the insertion port 110 is set at the front end of the slide groove 11; the first side walls 111 of the two slide grooves 11 may be adjacent to each other, so that the openings 118 of the two slide grooves 11 may be adjacent to each other. Among them, the first side wall 111 of the left slide groove 11 may be the right side wall, and the first side wall 111 of the right slide groove 11 may be the left side plate. Correspondingly, the second sliding part on the filter screen 2 may include a slide rail 21, and the two slide rails 21 may be inserted from the insertion ports 110 at the front ends of the two slide grooves 11, respectively, and slide backward into the slide groove 11.

[0066] It should be understood that in addition to setting a first sliding portion extending along the front-to-back direction on the left and right sides of the air inlet 10, and setting a second sliding portion extending along the front-to-back direction on the left and right sides of the filter 2, it is also possible to set a first sliding portion extending along the left-to-right direction on the front and back sides of the air inlet 10, and set a second sliding portion extending along the left-to-right direction on the front and back sides of the filter 2.

[0067] In some exemplary embodiments, Figure 3 As shown, the slide rail 21 includes a T-shaped (or dovetail-shaped) slide rail 21, the T-shaped slide rail 21 includes a first slide rail portion 212 and a second slide rail portion 213, the second slide rail portion 213 is connected to the middle portion of the first slide rail portion 212, the first slide rail portion 212 forms a first stop protrusion 211, the second slide rail portion 213 passes through the opening 118, and the slide groove 11 is a T-shaped slide groove 11.

[0068] The slide rail 21 may include a T-shaped slide rail 21, and the T-shaped slide rail 21 is horizontally placed, the first slide rail portion 212 thereof may be arranged longitudinally, the second slide rail portion 213 may be arranged transversely, and one end of the second slide rail portion 213 may be connected to the middle portion of the first slide rail portion 212. When the T-shaped slide rail 21 is slidably matched with the T-shaped slide groove 11, the first slide rail portion 212 of the T-shaped slide rail 21 may slide into the slide groove 11, and one end of the second slide rail portion 213 away from the first slide rail portion 212 may pass through the opening 118 of the first side wall 111 of the slide groove 11, so that one end of the second slide rail portion 213 away from the first slide rail portion 212 may be connected to the filter screen 2, and the opening 118 of the first side wall 111 of the slide groove 11 may avoid the second slide rail portion 213 of the slide rail 21.

[0069] The first rail portion 212 of the T-shaped rail 21 can form a first stop convex portion to prevent the rail 21 from slipping out of the opening 118 of the first side wall 111 of the slide slot 11, thereby affecting the sliding fit between the rail 21 and the slide slot 11. The T-shaped rails 21 on the left and right sides of the filter 2 cooperate with the T-shaped slide slots 11 on the left and right sides of the air inlet 10 of the face frame 1 to limit the position of the filter 2 in the up-down direction and the left-right direction.

[0070] The slide rail 21 and the slide groove 11 may be in other shapes besides T-shaped. For example, in some other exemplary embodiments, Fig.26 As shown, the slide rail 21 includes a wedge-shaped slide rail (with a trapezoidal cross section), the triangular protrusions on both sides of the wedge-shaped slide rail 21 form a first stop protrusion 211, and the slide groove 11 is a wedge-shaped slide groove (with a trapezoidal cross section). The cross-sectional area of ​​one end of the wedge-shaped slide rail 21 is smaller than the cross-sectional area of ​​the other end. The end of the wedge-shaped slide rail 21 with a larger cross-sectional area is away from the filter screen 2 and can slide into the wedge-shaped slide groove 11, and the end of the wedge-shaped slide rail 21 with a smaller cross-sectional area is close to the filter screen 2.

[0071] In some exemplary embodiments, Figure 2 , Figure 6 , Figure 8 and Fig.13 As shown, at least one of the insertion end 219 of the slide rail 21 and the insertion opening 110 of the slide slot 11 is provided with a guide slope 218 for facilitating the insertion end 219 of the slide rail 21 to slide into the insertion opening 110. In cooperation with the insertion opening 110 at the front end of the slide slot 11, the insertion end 219 of the slide rail 21 can be the rear end.

[0072] The insertion end 219 of the slide rail 21 may be provided with a guide slope 218, so that the insertion end 219 of the slide rail 21 may be in a conical tip shape, and / or the insertion opening 110 of the slide slot 11 may be provided with a guide slope, so that the insertion opening 110 may be in a conical expansion shape. The provision of the guide slope 218 facilitates the insertion end 219 of the slide rail 21 to slide into the insertion opening 110 of the slide slot 11, thereby facilitating the sliding installation of the filter screen 2 to the face frame 1.

[0073] In some exemplary embodiments, Figure 2 , Figure 6 , Figure 8 and Fig.13 As shown, the slide rail 21 includes a T-shaped slide rail 21, and a first side wall surface of the first slide rail portion 212 close to the second slide rail portion 213, a second side wall surface away from the second slide rail portion 213, and an insertion end 219 of at least one of the third side wall surface and the fourth side wall surface located between the first side wall surface and the second side wall surface is provided with a guide slope 218.

[0074] When T-shaped slide rails 21 are provided on the left and right sides of the filter 2, the first side wall surface of the first slide rail portion 212 close to the second slide rail portion 213 and the second side wall surface away from the second slide rail portion 213 can be the left and right side wall surfaces of the first slide rail portion 212 respectively, and the third side wall surface and the fourth side wall surface of the first slide rail portion 212 located between the first side wall surface and the second side wall surface can be the upper and lower side wall surfaces of the first slide rail portion 212 respectively. A guide inclined surface 218 can be provided at the insertion end 219 of at least one of the left and right side wall surfaces and the upper and lower side wall surfaces of the first slide rail portion 212, such as: a guide inclined surface 218 can be provided at the insertion end 219 of the left and right side wall surfaces and the upper and lower side wall surfaces of the first slide rail portion 212, so that the insertion end 219 of the slide rail 21 slides into the insertion port 110 of the slide groove 11, thereby facilitating the sliding installation of the filter 2 to the face frame 1.

[0075] In some exemplary embodiments, Figure 4 As shown, one of the surface frame 1 and the filter screen 2 having the slide groove 11 is also provided with a second stop protrusion 114 to prevent the slide rail 21 from escaping from the insertion opening 110 .

[0076] When the slide groove 11 is provided on the face frame 1 , a second stop protrusion 114 may also be provided on the face frame 1 , and the second stop protrusion 114 may prevent the slide rail 21 that has slid into place in the slide groove 11 from slipping out of the insertion port 110 , causing the filter screen 2 to fall off accidentally.

[0077] In some exemplary embodiments, Figure 4 As shown, the second stopping protrusion 114 is located outside the sliding groove 11 and adjacent to the insertion opening 110 , for example, the second stopping protrusion 114 may be located at the front side of the insertion opening 110 .

[0078] The chute 11 further includes a second side wall 112 and a third side wall 113 extending in the length direction, and the second side wall 112 and the third side wall 113 of the chute 11 are arranged opposite to each other and are both adjacent to the first side wall 111 of the chute 11. The first side wall 111 of the chute 11 may be the left side wall or the right side wall of the chute 11, and the second side wall 112 and the third side wall 113 of the chute 11 may be the upper and lower side walls of the chute 11, respectively.

[0079] There is a gap between the inner wall surface of the second side wall 112 of the slide groove 11 and the second stop convex portion 114 for the slide rail 21 to enter the insertion port 110. The inner wall surface of the third side wall 113 extending along the length direction of the slide groove 11 is provided with an avoidance recess 115 (see Figure 2-Figure 4 ), after the slide rail 21 slides into the slide groove 11, one end of the slide rail 21 adjacent to the second stop protrusion 114 can be bent and deformed into the avoidance recess 115 to cooperate with the second stop protrusion 114 for stopping.

[0080] like Figure 4 As shown, the height of the gap between the inner wall surface of the second side wall 112 of the slide groove 11 and the protruding end surface (such as the upper end surface) of the second stop protrusion 114 is H1, and the height of the slide rail 21 is H2, H1>H2, so that the slide rail 21 can enter the insertion port 110 of the slide groove 11 through the gap between the second stop protrusion 114 and the inner wall surface of the second side wall 112 of the slide groove 11, and then slide into the slide groove 11.

[0081] The inner wall surface of the third side wall 113 of the slide groove 11 is provided with an avoidance recess 115. After the slide rail 21 slides into place (the filter screen 2 is installed in place), one end of the slide rail 21 adjacent to the second stop convex portion 114 (e.g., the front end of the slide rail 21) is pressed to bend and deform into the avoidance recess 115 (e.g., bend and deform downward). At this time, one end of the slide rail 21 adjacent to the second stop convex portion 114 overlaps with the second stop convex portion 114 in height. The second stop convex portion 114 can prevent the slide rail 21 from slipping out of the insertion port 110, causing the filter screen 2 to accidentally fall off. When removing the filter screen 2, one end of the slide rail 21 adjacent to the second stop convex portion 114 can be bent in the opposite direction (e.g., bend upward), and then the slide rail 21 can be slid out of the slide groove 11, so that the filter screen 2 can be easily removed.

[0082] The slide rail 21 of the filter 2 cooperates with the slide groove 11 on the face frame 1 to limit the filter 2 in the up and down directions and left and right directions; the slide rail 21 of the filter 2 cooperates with the second stop protrusion 114 on the face frame 1 to limit the filter 2 in the front and back directions, thereby realizing the positioning of the filter 2 in the up and down, left and right, front and back directions, improving the installation reliability of the filter 2, and facilitating the disassembly and assembly of the filter 2.

[0083] In some other exemplary embodiments, Figure 14-17 As shown, one of the slide rail 21 and the slide slot 11 is provided with a snap 214 (see Fig.17 ), and the other is provided with a slot 116 that engages with the snap button 214 (see Fig.17 ), to prevent the slide rail 21 from sliding freely in the slide groove 11. The slide rail 21 may be provided with a snap 214, and the inner wall of the slide groove 11 may be provided with a clamping groove 116. Of course, the clamping groove 116 may also be provided on the slide rail 21, and the snap 214 may be provided on the inner wall of the slide groove 11.

[0084] The slide rail 21 and the slide groove 11 are respectively provided with a spring buckle 214 and a card slot 116. The spring buckle 214 can be engaged with the card slot 116 to prevent the slide rail 21 from sliding freely in the slide groove 11, thereby limiting the filter screen 2 in the front and rear directions and improving the installation reliability of the filter screen 2. The spring buckle 214 cooperates with the card slot 116 to facilitate the disassembly and assembly of the filter screen 2.

[0085] In some exemplary embodiments, Fig.17 As shown, multiple spring buckles 214 and card slots 116 are provided and matched one by one, wherein multiple spring buckles 214 can be arranged in sequence along the length direction of the slide rail 21 (such as: front and back direction), and multiple card slots 116 can be arranged in sequence along the length direction of the slide groove 11 (such as: front and back direction).

[0086] Each spring buckle 214 may include a connecting portion 215 and a snap portion 216. The first end of the connecting portion 215 may be connected to the slide rail 21, and the second end of the connecting portion 215 may extend toward a side close to the insertion port 110, or extend toward a side away from the insertion port 110. The snap portion 216 may be arranged at the second end of the connecting portion 215.
