[0038] The panel 200 assembly 10 for an indoor unit 20 of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] like Figures 1-6 As shown, the panel 200 assembly 10 for the indoor unit 20 of an air conditioner according to this embodiment of the present invention includes a mounting bracket 100 and a panel 200.

[0040] The mounting bracket 100 is provided with two guide clips 110, and the inner surface of a set of opposite ends of the panel 200 is provided with a locking portion 210. That is, there are also two locking portions 210, one on one end of the panel 200 and the other on the other end. For example, locking portions 210 are provided at the upper and lower ends of the panel 200 respectively. Here, the inner surface refers to the surface of the panel 200 facing the mounting bracket 100. A guide groove 220 is defined between the locking portion 210 and the panel 200. The two locking portions 210 are inserted into the two guide clips 110 in a one-to-one correspondence.

[0041] In some alternative embodiments, the tips of two guide buckles 110 are arranged opposite each other, and two guide grooves 220 are arranged back-to-back, that is, the openings of the two guide grooves 220 face opposite directions, and each guide buckle 110 is inserted into the corresponding guide groove 220. For example, the tip of one guide buckle 110 is arranged downwards, and the tip of the other guide buckle 110 is arranged upwards, with one guide buckle 110 located above the other guide buckle 110. One guide groove 220 is provided on the upper end of the panel 200, and the opening of this guide groove 220 is open upwards. The other guide groove 220 is provided on the lower end of the panel 200, and the opening of this other guide groove 220 is open downwards. The one guide buckle 110 is inserted upwards into the one guide groove 220, and the other guide buckle 110 is inserted downwards into the other guide groove 220.

[0042] In some alternative embodiments, the tips of the two guide clips 110 face the same direction, and the openings of the two guide grooves 220 face the same direction, with each guide clip 110 inserted into its corresponding guide groove 220. For example, one guide clip 110 may have its tip facing upwards, and the tip of the other guide clip 110 may also face upwards, with one guide clip 110 positioned above the other. One guide groove 220 is located on the upper end of the panel 200, with its opening facing downwards. The other guide groove 220 is located on the lower end of the panel 200, with its opening facing downwards. One guide clip 110 is inserted upwards into the first guide groove 220, and the other guide clip 110 is inserted upwards into the second guide groove 220.

[0043] When mounting panel 200 onto mounting bracket 100, the guide groove 220 at one end of panel 200 is engaged with a guide clip 110 on mounting bracket 100, and the guide groove 220 at the other end of panel 200 is engaged with another guide clip 110 on mounting bracket 100. This connects both ends of panel 200 to mounting bracket 100, preventing panel 200 from warping or deforming.

[0044] Understandably, when the guide groove 220 at the other end of panel 200 is inserted into another guide clip 110, since panel 200 is usually an injection molded part, panel 200 will deform under force, causing panel 200 to bend to a certain arc so that the other guide clip 110 can be inserted into the guide groove 220 at the other end of panel 200. After the other guide clip 110 is inserted into the guide groove 220 at the other end of panel 200, panel 200 will return from the bent state to the flat state due to its own elasticity.

[0045] like Figure 7 As shown, in the related technology, the panel 300 has multiple connecting clips 310 on the portion between its two ends in the vertical direction. These connecting clips 310 are spaced apart in the vertical direction, and the mounting bracket 400 has multiple corresponding slots 410 in the vertical direction. When installing the panel 300, the multiple connecting clips 310 are pushed into the corresponding slots 410 to engage, thereby mounting the panel 300 onto the mounting bracket 400. However, during actual installation, the panel 300 may bend and deform, especially when the indoor unit of the air conditioner is a cabinet unit, as the panel 300 is relatively long and prone to bending along its length. For example… Figure 7 As shown, because the panel 300 is bent in the vertical direction, after the upper part of the panel 300 is engaged with the mounting bracket 400, the lower part of the panel 300 warps away from the mounting bracket 400, making it difficult for the lower part of the panel 300 to align with its corresponding slot 410, thus preventing the panel 300 from being installed properly and causing inconvenience in installing the panel 300.

[0046] Compared with related technologies, the panel 200 assembly 10 of this utility model embodiment has two guide buckles 110 on its mounting frame 100, and corresponding snap-fit ​​portions 210 are provided on a set of opposite ends of the panel 200, forming guide grooves 220 between the snap-fit ​​portions 210 and the panel 200. Thus, by cooperating with the guide grooves 220 on the two ends of the panel 200 through the two guide buckles 110, the set of opposite ends of the panel 200 is first connected to the mounting frame 100. Since the set of opposite ends of the panel 200 is restricted by the mounting frame 100, the panel 200 will not warp, facilitating the engagement of the snap-fit ​​or positioning structure between the set of opposite ends of the panel 200, thereby solving the problem of inconvenient installation of the panel 200.

[0047] In addition, the panel 200 can be fixed to the mounting bracket 100 without additional snap-fit ​​or positioning structures between the opposite ends of the panel 200, by simply cooperating with the guide groove 220 and the guide buckle 110.

[0048] To make this application easier to understand, the panel 200 assembly 10 of this utility model embodiment is further described below with an example of a set of opposite ends of the panel 200 as the upper end and lower end of the panel 200, and two guide buckles 110 spaced apart in the vertical direction.

[0049] Optionally, the length of each guide clip 110 inserted into the corresponding guide groove 220 is 20mm to 50mm. Optionally, the length of each guide clip 110 inserted into the corresponding guide groove 220 is 27mm to 45mm. Optionally, the length of each guide clip 110 inserted into the corresponding guide groove 220 is 32mm to 36mm. Thus, the cooperation between the guide clips 110 and the guide grooves 220 allows for a more secure connection between the panel 200 and the mounting bracket 100.

[0050] The length of the portion of each guide buckle 110 inserted into the corresponding guide groove 220 includes, but is not limited to, 20mm, 27mm, 30mm, 35mm, 40mm, 42mm, 47mm, or 50mm.

[0051] In some embodiments, such as Figures 1-5 As shown, the mounting bracket 100 of this utility model embodiment includes a base 120, a first support plate 130, and a second support plate 140, both of which are disposed on the base 120. At least one of the first support plate 130 and the second support plate 140 is provided with a guide buckle 110 at its upper end, and the base 120 is provided with a guide buckle 110.

[0052] In some embodiments, the two guide buckles 110 have the same structure. Each guide buckle 110 includes a guide post 111 and a guide head 112 connected in sequence. Each guide head 112 is located at the end of the corresponding guide post 111 facing the other guide post 111.

[0053] That is, the lower guide buckle 110 extends upward, with its guide head 112 positioned above the corresponding guide post 111, and its corresponding guide groove 220 opening downward; the upper guide buckle 110 extends downward, with its guide head 112 positioned below the corresponding guide post 111, and its corresponding guide groove 220 opening upward. Alternatively, the lower guide buckle 110 extends downward, with its guide head 112 positioned below the corresponding guide post 111, and its corresponding guide groove 220 opening upward; the upper guide buckle 110 extends upward, with its guide head 112 positioned above the corresponding guide post 111, and its corresponding guide groove 220 opening downward.

[0054] The guide groove 220 is configured to conform to the shape of the corresponding guide buckle 110. That is, the shape of the guide groove 220 is adapted to the guide buckle 110, allowing the panel 200 to be more securely connected to the mounting bracket 100 after the guide buckle 110 is inserted into the guide groove 220. Specifically, the snap-fit ​​portion 210 includes a first section and a second section. The first section is connected to the inner surface of the panel 200, and the second section is connected to the first section. The first section forms an angle with the panel 200, and the second section is generally parallel to the panel 200, so that the first section, the second section, and the panel 200 form a guide groove 220 that adapts to the guide buckle 110.

[0055] The guide head 112 of the guide buckle 110 is guided by the guide groove 220, allowing the guide buckle 110 to smoothly insert into the guide groove 220. Especially when the guide buckle 110 at the other end of the panel 200 is inserted into its corresponding guide groove 220 first, the guide head 112 of the guide buckle 110 at that end cooperates with the guide groove 220, guiding the guide buckle 110 at that end to smoothly and completely insert into the guide groove 220, so that the panel 200 naturally flattens out from a bent state, ensuring that the panel 200 can be installed in place, thereby reducing the assembly difficulty of the panel 200 assembly 10.

[0056] In some embodiments, such as Figure 2 and Figure 3As shown, the two guide buckles 110 have different structures. The lower guide buckle 110 includes a guide post 111 and a guide head 112 connected in sequence. The guide head 112 is located above the corresponding guide post 111, and its corresponding guide groove 220 is set with its opening facing downward. The upper ends of the first support plate 130 and the second support plate 140 have a limiting plate 150, which forms the upper guide buckle 110. The limiting plate 150 contacts and abuts against the wall of the upper guide groove 220.

[0057] Furthermore, the surface of the guide head 112 facing away from the panel 200 is a guide surface 113. The distance between one end of the guide surface 113 and the panel 200 is greater than the distance between the other end of the guide surface 113 and the panel 200. That is, the guide surface 113 is an inclined surface, and the end of the inclined surface adjacent to the panel 200 is farther away from the guide post 111 than the other end. Therefore, when the guide head 112 is inserted into the guide groove 220, the guide surface 113 of the guide head 112 can guide the guide head 112 to move into the guide groove 220, thus allowing the guide latch 110 to be smoothly and completely inserted into the guide groove 220.

[0058] Optionally, the angle between the guide surface 113 and the inner surface of the panel 200 is 30° to 60°. Optionally, the angle between the guide surface 113 and the inner surface of the panel 200 is 35° to 50°. Optionally, the angle between the guide surface 113 and the inner surface of the panel 200 is 41° to 46°. On the one hand, this avoids an excessively large angle between the guide surface 113 and the inner surface of the panel 200, thus reducing the friction when the guide surface 113 contacts the panel 200, allowing the guide latch 110 to be inserted into the guide groove 220 more smoothly. On the other hand, this allows the guide latch 110 to be guided by the guide surface 113 to be inserted smoothly into the guide groove 220.

[0059] The included angle between the guide surface 113 and the inner surface of the panel 200 includes, but is not limited to, 30°, 35°, 41°, 48°, 50°, 55°, 57° or 60°.

[0060] In some embodiments, such as Figure 2 and Figure 3As shown, the surface of the guide head 112 facing the panel 200 includes a first region 114 and a second region 115. The first region 114 is connected to the guide post, and the second region 115 is connected to the guide surface 113 and the first region 114. The first region 114 is parallel to the inner surface of the panel 200, and the second region 115 is an inclined surface. The distance between one end of the second region 115 connecting to the first region 114 and the panel 200 is smaller than the distance between the other end of the second region 115 and the panel 200. That is, the second region 115 guides the panel 200, making it easier for the panel 200 to move towards the guide surface 113, which facilitates the smooth insertion of the panel 200 into the guide groove 220.

[0061] For example Figure 2 As shown, taking the guide groove 220 and guide buckle 110 located below as an example, the upper end of the guide surface 113 of the guide head 112 is located in front of the lower end of the guide surface 113, and the upper end of the second region 115 of the guide head 112 is located behind the lower end of the second region 115. When installing the guide buckle 110 and the guide groove 220, the second region 115 guides the panel 200 to move backward, and the guide panel 200 as a whole moves upward or bends. Thus, the second region 115 not only guides the lower end of the panel 200 to move towards the guide surface 113, but also allows the panel 200 to avoid the guide head 112, so that the lower end of the panel 200 can move smoothly backward. Therefore, it is beneficial to smoothly insert the guide buckle 110 into the guide groove 220, further reducing the assembly difficulty of the panel 200 assembly 10.

[0062] In other embodiments, such as Figure 2 and Figure 3 As shown, the surface of the guide head 112 facing the panel 200 is parallel to the inner surface of the panel 200. That is, compared to the surface of the guide head 112 facing the panel 200, which includes the first region 114 and the second region 115, the guide surface 113 in this embodiment has a larger guide surface area, making it easier for the panel 200 to be stretched and flattened after the guide groove 220 of the panel 200 engages with the guide surface 113. Furthermore, the parallelism between the surface of the guide head 112 facing the panel 200 and the inner surface of the panel 200 makes it less likely for the guide latch 110 to detach from the guide groove 220, improving the stability of the connection between the panel 200 and the mounting bracket 100.

[0063] In some embodiments, the ratio between the length of the guide head 112 and the length of the guide post 111 is 2 / 3 to 1. This not only allows the guide head 112 to better guide the panel 200 so that the guide clip 110 can be smoothly inserted into the guide groove 220, but also ensures that the guide clip 110 is less likely to fall out of the guide groove 220 after it is inserted, thus improving the stability of the installation.

[0064] The ratio between the length of the guide head 112 and the length of the guide post 111 is, but is not limited to, 2 / 3, 5 / 6 or 1.

[0065] In some embodiments, the panel 200 and the mounting bracket 100 are connected by a plurality of connecting clips (not shown in the figure). Specifically, the panel 200 is provided with a plurality of connecting clips, which are disposed on the inner surface of another set of opposite ends of the panel 200, and the snap-fit ​​portions 210 are disposed at both ends of the panel 200 along its length direction.

[0066] The first support plate 130 and the second support plate 140 are provided with multiple slots, and multiple connecting buckles are engaged in the slots one by one to make the connection between the panel 200 and the mounting bracket 100 more secure.

[0067] In addition, the two ends of the panel 200 are connected to the mounting bracket 100 through guide buckles 110 and guide grooves 220, so that the panel 200 will not bend or deform, thereby greatly improving the convenience of multiple connecting buckles and multiple grooves.

[0068] One of the panel 200 and the mounting bracket 100 is provided with a positioning protrusion, and the other is provided with a positioning groove or positioning hole, into which the positioning protrusion is inserted. That is, the panel 200 is provided with a positioning protrusion, and the mounting bracket 100 is provided with a positioning groove; or, the mounting bracket 100 is provided with a positioning protrusion, and the panel 200 is provided with a positioning groove. Thus, guided by the positioning protrusion and the positioning groove, multiple connecting clips can more easily be engaged with multiple slots.

[0069] like Figure 8 As shown, the indoor unit 20 of the air conditioner in this embodiment of the present invention includes a housing and a panel 200 assembly 10. The panel 200 assembly 10 is the panel 200 assembly 10 in any of the above embodiments, and the mounting bracket 100 of the panel 200 assembly 10 is disposed on the housing.

[0070] In this embodiment of the air conditioner indoor unit 20, the mounting bracket 100 of the panel 200 assembly 10 is provided with two guide buckles 110, and corresponding snap-fit ​​portions 210 are provided on a set of opposite ends of the panel 200, forming guide grooves 220 between the snap-fit ​​portions 210 and the panel 200. Thus, by engaging the guide grooves 220 on the two ends of the panel 200 with the two guide buckles 110, the set of opposite ends of the panel 200 is first installed with the mounting bracket 100. Since the set of opposite ends of the panel 200 is restricted by the mounting bracket 100, the panel 200 will not warp, facilitating the engagement or positioning of the snap-fit ​​structure between the set of opposite ends of the panel 200. Therefore, the problem of inconvenient installation of the panel 200 is solved, and the installation efficiency of the air conditioner indoor unit 20 of this embodiment of the invention is improved.

[0071] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
