[0043] The panel structure of the present invention includes an air inlet panel 10 and an air inlet grille 20, the air inlet panel 10 has an air inlet opening 100; the air inlet grille 20 is detachably arranged at the air inlet opening 100; wherein, a first clamping portion 11 is arranged on the air inlet panel 10, and a second clamping portion 21 is arranged on the air inlet grille 20, the first clamping portion 11 and the second clamping portion 21 cooperate with each other to position the air inlet grille 20 on the air inlet panel 10, the present invention realizes the pre-fixation between the air inlet grille 20 and the air inlet panel 10 by the mutual cooperation of the evenly distributed first clamping portion 11 and the second clamping portion 21, thus making the installation between the air inlet grille 20 and the air inlet panel 10 more stable, solving the problem of the difficulty of assembling the panel structure in the prior art.

[0044] Specifically, one of the first clamping portion 11 and the second clamping portion 21 is a buckle, and the other of the first clamping portion 11 and the second clamping portion 21 is a bayonet matched with the buckle.

[0045] In an embodiment of the present invention, the first clamping portion 11 is a bayonet, and the second clamping portion 21 is a buckle that cooperates with the bayonet, so that when the air inlet grille 20 is assembled on the air inlet panel 10, at least part of the buckle passes through the bayonet to be clamped at the bayonet.

[0046] Preferably, there are multiple first clamping parts 11 and multiple second clamping parts 21, and the multiple first clamping parts 11 and the multiple second clamping parts 21 are arranged one by one. In this way, the assembly between the air inlet grille 20 and the air inlet panel 10 is more stable.

[0047] Specifically, the air inlet grille 20 has a first side beam and a second side beam that are relatively arranged, and the first side beam and the second side beam both extend along the extension direction of the air inlet grille 20, and the first side beam and the second side beam are both provided with a second clipping portion 21; the air inlet panel 10 is provided with a plurality of first clipping portions 11 corresponding to the plurality of second clipping portions 21 on the air inlet grille 20.

[0048] like Figure 1As shown, the air inlet panel 10 includes a plurality of cross beams 12, and the plurality of cross beams 12 are all arranged in the air inlet opening 100; at least one end of at least one cross beam 12 among the plurality of cross beams 12 is provided with a first clamping portion 11; and a second clamping portion 21 corresponding to the first clamping portion 11 on the cross beam 12 is provided at a corresponding position of the air inlet grille 20.

[0049] Specifically, a plurality of beams 12 are arranged at intervals along the height direction of the air conditioner indoor unit.

[0050] Specifically, the air inlet panel 10 is provided with a first latch portion 13 , and the air inlet grille 20 is provided with a second latch portion 22 matched with the first latch portion 13 .

[0051] like Fig.13 As shown, the first latch portion 13 is a latch hole, and the second latch portion 22 is a latch column; and / or the first latch portion 13 is arranged on the top of the air inlet panel 10, and the second latch portion 22 is arranged on the top of the air inlet grille 20. In this way, the air inlet grille and the air inlet panel are positioned by pins to limit the up and down movement.

[0052] In the design of the air conditioner cabinet, for the structure in which the air inlet grille 20 and the air inlet panel 10 are separated, evenly distributed latches and buckles are added to the air inlet grille 20, and corresponding buckle holes are distributed on the air inlet panel 10. When assembling the air inlet grille 20 and the air inlet panel 10, the air inlet grille 20 is first placed on the air inlet panel 10, and the assembly between the air inlet grille and the air inlet panel is pre-fixed by these buckles, so that the air inlet grille will not fall off or be damaged during transportation or fixing the air inlet grille and flipping the air inlet panel. After that, the air inlet panel is flipped over and screws are driven in to lock the air inlet grille and the air inlet panel, thereby optimizing the assembly between the air inlet panel and the air inlet grille.

[0053] Among them, the air intake grille and panel assembly require the top to remain in the same plane to beautify the appearance, make the assembly more stable, and easier to meet the needs of optimizing the appearance.

[0054] When assembling the air inlet panel and grille, if the mating parts of the panel and grille are completely flat, there will be an assembly gap on the left and right sides of the cabinet, which will affect the aesthetics of the cabinet. Figure 8 As shown, a bendable slanted retaining rib 18 is designed on the side of the air inlet panel 10, and the edge of the air inlet grille is changed from a square straight surface to a triangular cross-section, which cooperates with the retaining rib 18. This design can make the assembly gap of the straight surface hidden, and the matching gap will not be too conspicuous, which is conducive to improving the aesthetics and user experience.

[0055] like Figure 8As shown, the width B of the retaining rib 18 is 1 mm, the length L of the retaining rib 18 is 2 mm, and the gap a between the retaining rib 18 and the edge of the triangular cross section of the air inlet grille 20 is 0.5 mm.

[0056] Specifically, a rear cover mounting opening 14 is provided on the air inlet panel 10, and the panel structure also includes: a rear cover 30, which is detachably mounted at the rear cover mounting opening 14; wherein, a first assembly portion 31 is provided on the rear cover 30, and a second assembly portion 23 is provided on the air inlet grille 20, and the first assembly portion 31 and the second assembly portion 23 cooperate with each other so as to be jointly mounted on the air inlet panel 10 after the rear cover 30 and the air inlet grille 20 are assembled.

[0057] In an embodiment of the present invention, Figure 1 and Fig. 9 As shown, the first assembling portion 31 and the second assembling portion 23 are both provided with holes, so that the rear cover 30 and the air intake grille 20 can be assembled by means of first fasteners provided in the first assembling portion 31 and the second assembling portion 23 .

[0058] Specifically, the air inlet panel 10 is provided with a connection hole, and the air inlet grille 20 is provided with a connection column 24 , so that the air inlet panel 10 and the air inlet grille 20 are fixed by a second fastener penetrating through the connection hole and the connection column 24 .

[0059] like Figure 1 As shown, a first assembling protrusion 25 is provided on the air inlet grille 20, the second assembling portion 23 is provided on the first assembling protrusion 25, and the first assembling protrusion 25 is located on the inner side of the rear cover 30; and / or the first assembling portion 31 is provided on the top of the rear cover 30; and / or a plug-in protrusion 32 is provided on the bottom of the rear cover 30, and a plug-in groove 15 is provided on the air inlet panel 10, and the plug-in protrusion 32 is inserted into the plug-in groove 15.

[0060] Specifically, there are a plurality of plugging protrusions 32 and a plurality of plugging grooves 15 , and the plurality of plugging protrusions 32 and the plurality of plugging grooves 15 are arranged in a one-to-one correspondence.

[0061] Specifically, a third clamping portion 33 is provided on the rear cover 30 , and a fourth clamping portion 16 is provided on the air inlet panel 10 . The third clamping portion 33 cooperates with the fourth clamping portion 16 to fix the rear cover 30 and the air inlet panel 10 together.

[0062] Specifically, a snap-fit ​​structure is used between the rear cover 30 and the air inlet panel 10. The plug-in structure and the snap-fit ​​structure cooperate to make the installation of the rear cover 30 more stable, prevent the screws from being misaligned due to vibration when being driven in, and prevent an assembly step from being generated on the top of the rear cover, thereby ensuring the flatness of the top end.

[0063] In an embodiment of the present invention, Figure 2 and Fig.10As shown, the third clamping portion 33 is a rear cover clamp, and the fourth clamping portion 16 is a panel clamp. The clamping head of the panel clamp is clamped and matched with the clamping head of the rear cover clamp.

[0064] Specifically, an insertion opening 17 is provided on the air inlet panel 10, and the panel buckle is arranged on the inner side of the insertion opening 17 so as to be engaged with the clamping head of the panel buckle after the clamping head of the rear cover buckle passes through the insertion opening 17; and / or the panel buckle has an elastic arm, and the clamping head of the panel buckle is arranged at the end of the elastic arm, so that the rear cover 30 clamping presses the panel buckle to deform so as to be clamped into the side of the clamping head of the panel buckle away from the rear cover 30.

[0065] In the prior art, the assembly of the rear cover and the air inlet grille is usually based on the air inlet panel. Due to the existence of assembly tolerance, the fit between the rear cover and the air inlet grille requires a maximum assembly gap to be reserved, resulting in two large assembly gaps between the grille and the rear cover, and between the rear cover and the bottom, affecting the fit and aesthetics.

[0066] For example, the dimensional tolerance of the length of the detachable grille of the cabinet air inlet component is ±1.0mm, and the dimensional tolerance of the rear cover is ±0.5mm. If the assembly of both is based on the air inlet panel, the assembly gap between the grille and the rear cover needs to be reserved for 1.5mm, and the gap between the two components is relatively large. The assembly gap between the rear cover and the air inlet panel must also meet the dimensional tolerance of the rear cover. In this way, two relatively obvious assembly gaps will appear between the air inlet panel and the rear cover, and between the rear cover and the air inlet grille, affecting the appearance.

[0067] In the specific process of the embodiment of the present invention, the rear cover 30 is first assembled with the air inlet grille 20. The rear cover 30 uses the air inlet grille 20 as the assembly reference, and adopts the snap-on positioning and the through-hole (the first assembly part 31 and the second assembly part 23 cooperate) to limit the position, so that the air inlet grille 20 and the rear cover 30 are integrated, and the assembly gap is minimized. Then, the assembled rear cover and air inlet grille are assembled with the air inlet panel.

[0068] Specifically, Figure 1 and Fig. 9 As shown, the second assembly part of the air inlet grille includes a plurality of baffles, which limit the up and down deviation of the rear cover. The screws pass through the first assembly part 31 and the second assembly part 23 to lock the air inlet grille and the rear cover, thereby realizing the integration of the air inlet grille and the rear cover. The assembly gap between the air inlet grille and the rear cover can be reduced to 0.5mm, and only the assembly gap between the rear cover and the air inlet panel needs to be considered. In this way, the obvious assembly gap is reduced from two to one, thereby maximizing the reduction of the assembly gap and realizing the optimization of the gap between the assembly of each part in each component of the air inlet panel.

[0069] like Figure 4As shown, the panel structure further includes: a fixing member 200 , which is passed through the air inlet panel 10 and the air inlet grille 20 to fix the air inlet grille 20 and the air inlet panel 10 after the air inlet grille 20 is positioned on the air inlet panel 10 .

[0070] The present invention also provides an air-conditioner indoor unit, comprising a panel structure, and the panel structure is the above-mentioned panel structure.

[0071] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0072] The panel structure of the present invention includes an air inlet panel 10 and an air inlet grille 20, the air inlet panel 10 has an air inlet opening 100; the air inlet grille 20 is detachably arranged at the air inlet opening 100; wherein, a first clamping portion 11 is arranged on the air inlet panel 10, and a second clamping portion 21 is arranged on the air inlet grille 20, the first clamping portion 11 and the second clamping portion 21 cooperate with each other to position the air inlet grille 20 on the air inlet panel 10, the present invention realizes the pre-fixation between the air inlet grille 20 and the air inlet panel 10 by the mutual cooperation of the evenly distributed first clamping portion 11 and the second clamping portion 21, thus making the installation between the air inlet grille 20 and the air inlet panel 10 more stable, solving the problem of the difficulty of assembling the panel structure in the prior art.
