[0054] Figure 1 is a schematic front view of an air conditioner indoor unit according to an embodiment of the utility model, as shown Figure 1 As shown, and refer to Figure 2-15 The embodiment of the utility model provides a decorative panel 400 of an indoor unit of an air conditioner. The decorative panel 400 includes a panel body 490 , a slide groove structure 420 and a card insertion structure 430 .

[0055] The plate body 490 includes a first end 491 and a second end 492 which are spaced apart and arranged opposite to each other along the length direction thereof. The slide groove structure 420 is fixedly connected to the back side of the plate body 490 and is located at the first end 491. A first slide groove 421 is formed in the slide groove structure 420, and the first slide groove 421 has a first opening 422 which is away from the second end 492. The card insertion structure 430 protrudes outward from the back side and is located at the second end 492.

[0056] The air conditioner indoor unit may be a cabinet unit, a wall mounted unit, etc. In this embodiment, the air conditioner indoor unit is taken as a cabinet unit as an example to illustrate the technical solution of this application.

[0057] Specifically, the air conditioner indoor unit is vertically arranged, and the decorative plate 400 is vertically installed at the front side of the housing 100 of the air conditioner indoor unit. The first end 491 may be the upper end of the plate body 490, and the second end 492 may be the lower end of the plate body 490.

[0058] The plate body 490 may be flat or curved, such as an arcuate surface, without limitation. Preferably, the plate body 490 is an arcuate surface, with the convex side being the front surface and the concave side being the back surface.

[0059] The slide groove structure 420 is fixedly connected to the back of the plate body 490, and preferably the slide groove structure 420 is integrally formed on the plate body 490. The first slide groove 421 has a first opening 422 facing upward. Correspondingly, the front side of the housing 100 may be provided with a slide structure 320 matching the first slide groove 421, such as a slide plate. Fig.11 As shown, the end of the sliding plate extends downward so that when the decorative plate 400 slides upward, the sliding plate is inserted into the first sliding groove 421. The sliding groove structure 420 can fix the decorative plate 400 in the front-rear direction.

[0060] In this embodiment, the card insertion structure 430 is fixedly connected to the back of the plate body 490, and preferably the card insertion structure 430 is integrally formed on the plate body 490. The card insertion structure 430 may include a cylindrical buckle protruding backwards, and the front side of the corresponding housing 100 may be provided with a card hole structure 330 matching the cylindrical buckle, such as an elastic hole, such as Fig.10 As shown, when the card insertion structure 430 is pressed or pushed backward, the column buckle is squeezed into the elastic hole. The card insertion structure 430 can fix the decorative plate 400 in the left-right direction and the up-down direction.

[0061] During installation, the decorative plate 400 is first tilted slightly outward, that is, the second end 492 is slightly away from the housing 100. The first opening 422 of the slide groove structure 420 is aligned with the slide structure 320, and then the decorative plate 400 is slid upward to cause the slide structure 320 to be slidably installed in the first slide groove 421. At this time, the card insertion structure 430 is outside the card hole structure 330. Align the card insertion structure 430 with the card hole structure 330, and gently tap the outer surface of the second end 492 of the decorative plate 400 to insert the card insertion structure 430 into the card hole structure 330.

[0062] During disassembly, firstly lightly buckle the second end 492 outwards to disengage the card insertion structure 430 from the card hole structure 330, and then slide the decorative plate 400 downwards to disengage the slide groove structure 420 from the slide insertion structure 320, and the disassembly is completed.

[0063] Compared with the prior art, the decorative panel 400 is not installed by screws and can be assembled and disassembled by hand, which is convenient and can avoid the phenomenon of screws falling off.

[0064] In some embodiments of the decorative plate of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, there are two slide groove structures 420 , which are arranged opposite to each other at intervals along the width direction of the plate body 490 .

[0065] In this embodiment, there are two slide groove structures 420, which are arranged opposite to each other in a lateral direction, and the two first slide grooves 421 opening upward on the left and right sides form a sliding connection with the corresponding two slide structures 320 on the housing 100. On the one hand, the firmness of the connection can be improved, and the decorative plate 400 can be fixed in the front-to-back direction. On the other hand, the two slide groove structures 420 are arranged opposite to each other, and the decorative plate 400 can also be limited in the left-right direction.

[0066] Preferably, the two slide groove structures 420 are symmetrically arranged along the lateral center of the decorative plate 400 , and the distance between the two slide groove structures 420 is greater than 1 / 2 of the lateral width of the decorative plate 400 .

[0067] In some embodiments of the decorative plate of the present invention, Figure 5 , Figure 11-13 As shown, the slide groove structure 420 includes a first side wall 423 , a second side wall 424 , and a third side wall 425 .

[0068] The first side wall 423 protrudes outward from the back side and extends along the length direction of the plate body 490. The second side wall 424 protrudes outward from the back side and extends along the width direction of the plate body 490, and intersects with the first side wall 423. The third side wall 425 is parallel to the back side and is fixedly connected to the ends of the first side wall 423 and the second side wall 424 away from the back side.

[0069] The first opening 422 is formed at an end of the first side wall 423 and the third side wall 425 away from the second end portion 492 .

[0070] In this embodiment, a chamfer can be set at the connection between the first side wall 423 and the second side wall 424, and the first opening 422 is the upper end of the first slide groove 421. The third side wall 425 is used to limit the decorative plate 400 in the front-to-back direction, the first side wall 423 is used to limit the decorative plate 400 in the left-to-right direction, and the second side wall 424 is used to limit the sliding operation. When the lower end of the sliding structure 320 contacts the second side wall 424, it indicates that the sliding installation has been completed.

[0071] In some embodiments of the decorative plate of the present invention, Fig.13 As shown, the slide groove structure 420 also includes a limiting rib 426, which is integrally formed on a side of the third side wall 425 close to the back. The limiting rib 426 extends along the length direction of the plate body 490, one end of the limiting rib 426 in the length direction is located at the first opening 422, and the other end is fixedly connected to the second side wall 424. From the first opening 422 to the second side wall 424, the width of the limiting rib 426 gradually increases.

[0072] The limiting rib 426 protrudes backward from the third side wall 425 and is used to contact the front surface of the sliding structure 320. Compared with the third side wall 425 directly contacting the front surface of the sliding structure 320, this embodiment can reduce the relative friction area during the sliding installation and increase the resistance pressure between the limiting rib 426 and the sliding structure 320.

[0073] On the other hand, the lateral width of the limiting rib 426 gradually increases from top to bottom, which can reduce the friction between the limiting rib 426 and the sliding structure 320 at the initial stage of the sliding installation operation, and increase the friction between the limiting rib 426 and the sliding structure 320 after the sliding installation is completed, thereby facilitating installation and improving the firmness of the connection.

[0074] In some embodiments of the decorative plate of the present invention, Figure 11-13 As shown, the slide structure 420 also includes a support rib 427, which is integrally formed on the back and extends along the length direction of the plate body 490. One end of the support rib 427 away from the second end 492 is fixedly connected to the second side wall 424. A plurality of support ribs 427 are arranged at intervals along the width direction of the plate body 490, and an anti-shrinkage groove is formed between two adjacent support ribs 427.

[0075] The support ribs 427 are vertically arranged to support the first side wall 423 , the second side wall 424 and the third side wall 425 at the lower end, thereby improving the structural strength of the slide groove structure 420 and providing a firm support for the sliding installation.

[0076] The anti-shrinkage groove is used to prevent shrinkage dents from occurring during the integral molding of the decorative panel 400, especially to prevent dents from occurring on the front surface of the decorative panel 400 directly facing the slide groove structure 420, which affects the structural strength and the appearance of the air conditioner.

[0077] In some embodiments of the decorative plate of the present invention, Figure 4 and Fig.15 As shown, the decorative plate 400 further includes at least one positioning slider 470 , which is integrally formed on the back and is located between the slide groove structure 420 and the card insertion structure 430 in the length direction of the plate body 490 .

[0078] The positioning slider 470 includes an annular peripheral wall.

[0079] The positioning slider 470 can be circular, square, etc., preferably annular, and is composed of an annular peripheral wall to reduce the thickness and avoid shrinkage marks during manufacturing.

[0080] A guide groove may be provided at a position on the front surface of the housing 100 corresponding to the positioning slide block 470, such as Figure 8As shown, when the decorative plate 400 is slid upward for insertion, the positioning slider 470 can slide upward in the guide groove. On the one hand, the positioning slider 470 can limit the sliding operation of the decorative plate 400 upward to prevent the decorative plate 400 from tilting left and right when sliding upward. On the other hand, when installed in place, the guide groove can also limit the positioning slider 470, that is, further limit the decorative plate 400 to prevent the decorative plate 400 from shaking after installation.

[0081] Preferably, the positioning slider 470 is disposed at the center of the transverse width of the decorative plate 400. A plurality of positioning sliders 470 may be provided, which are spaced apart along the vertical length direction of the decorative plate 400.

[0082] In some embodiments of the decorative plate of the present invention, Figure 2 , Figure 4-7 As shown, the decorative plate 400 further includes a first longitudinal limiting rib 411, and the first longitudinal limiting rib 411 is integrally formed on the back side.

[0083] There are two first longitudinal limiting ribs 411 arranged at intervals along the width direction of the plate body 490 , and each first longitudinal limiting rib 411 is arranged parallel to a long side of an adjacent plate body 490 and at intervals.

[0084] The sliding groove structure 420 and the card insertion structure 430 are both located between the two first longitudinal limiting ribs 411 .

[0085] The first longitudinal limiting ribs 411 are used to improve the structural strength of the decorative plate 400 and prevent deformation of the decorative plate 400. Specifically, the first longitudinal limiting ribs 411 are arranged in parallel and at intervals on the inner side of the vertical length of the plate body 490 to improve the structural strength of the decorative plate 400 in the length direction.

[0086] In particular, when the length-to-width ratio of the decorative panel 400 is relatively large, the first longitudinal limiting ribs 411 can effectively improve the structural strength of the high decorative panel 400 in the length direction.

[0087] Preferably, the thickness of the first longitudinal limiting rib 411 is less than 1 / 2 of the thickness of the plate body 490 to prevent shrinkage marks from being generated during manufacturing.

[0088] In some embodiments of the decorative plate of the present invention, Figure 4 , Figure 6 and Fig.14 As shown, the decorative plate 400 further includes a second buckle structure 480 , which protrudes outward from the back. There are multiple second buckle structures 480 arranged at intervals, and each second buckle structure 480 is fixedly connected to a first longitudinal limiting rib 411 .

[0089] In this embodiment, the second buckle structure 480 is used to further improve the firmness of the installation of the decorative plate 400. The front surface of the housing 100 may be provided with a second buckle corresponding to the second buckle structure 480, such as Fig. 9 As shown, the second buckle structure 480 is buckled into connection with the second buckle.

[0090] The second buckle structures 480 are adjacent to and fixedly connected to the first longitudinal limiting ribs 411. On the one hand, the structural strength of the second buckle structures 480 can be improved by means of the first longitudinal limiting ribs 411. On the other hand, support can be provided to the first longitudinal limiting ribs 411 to improve the structural strength of the first longitudinal limiting ribs 411.

[0091] The plurality of second buckle structures 480 may form two columns, and the plurality of second buckle structures 480 in each column are spaced apart along the length direction of the first longitudinal limiting rib 411 .

[0092] In some embodiments of the decorative plate of the present invention, Figure 4 , Figure 12-13 As shown, there are two slide groove structures 420 , which are arranged opposite to each other at intervals along the width direction of the plate body 490 .

[0093] A sliding groove structure 420 and a first longitudinal limiting rib 411 adjacent to each other are also fixedly connected by a connecting rib 428. The connecting rib 428 is integrally formed on the back surface and extends along the width direction of the plate body 490.

[0094] A surface of the connecting rib 428 away from the second end portion 492 is flush with the first opening 422 .

[0095] In this embodiment, the chute structure 420 is fixedly connected to the first longitudinal limiting rib 411 through the connecting rib 428. On the one hand, the structural strength of the chute structure 420 can be improved by means of the first longitudinal limiting rib 411. On the other hand, support can be provided to the first longitudinal limiting rib 411 to improve the structural strength of the first longitudinal limiting rib 411.

[0096] In some embodiments of the decorative plate of the present invention, Figure 4 As shown, the decorative plate 400 further includes a plurality of transverse limiting ribs 460, each of which is integrally formed on the back. Among them, at least one transverse limiting rib 460 is disposed on the two edges of the first end 491 and the second end 492 that are away from each other. The height of the transverse limiting rib 460 is less than the height of the first longitudinal limiting rib 411.

[0097] In this embodiment, the transverse limiting rib 460 is at least arranged on the upper edge of the first end 491 and the lower edge of the second end 492, which can improve the structural strength of the upper and lower edges of the plate body 490 and also improve the structural strength of the plate body 490 along the transverse width direction.
