[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figures 1 to 5As shown, embodiment 1 of the present invention provides a screw cover plate 20, which is used to be set on the indoor unit housing 10 of the air-conditioning indoor unit, so that the screw cover plate 20 is covered on the outside of the screw 30 to avoid the screw 30 from being exposed, thereby improving the appearance of the air-conditioning indoor unit. The screw cover 20 includes a plate body 21, a clamping structure 22 and a positioning structure 23. The clamping structure 22 is arranged at one end of the plate body 21. The clamping structure 22 includes a clamping portion 221 and a butting portion 222. The butting portion 222 is arranged at the end of the clamping portion 221. The clamping portion 221 is used to clamp with the bottom shell 11 of the indoor unit casing 10. The butting portion 222 protrudes from the clamping portion 221. The butting portion 222 is used to butt and limit with the bottom shell 11 of the indoor unit casing 10 to prevent the clamping portion 221 from falling off the bottom shell 11 of the indoor unit casing 10, and one end of the plate body 21 is movably arranged on the bottom shell 11 of the indoor unit casing 10 through the clamping portion 221. The positioning structure 23 is arranged at the other end of the plate body 21. The positioning structure 23 is adapted to the structure of the positioning part of the bottom shell 11 of the indoor unit housing 10, so that the other end of the plate body 21 is fixed with the cooperation of the positioning structure 23 and the positioning part, which is not easy to fall off, thereby improving the stability of the setting and the aesthetic appearance.

[0027] Specifically, the plate body 21 in this embodiment is a strip-shaped structure, and the plate body 21 has one end and the other end that are arranged opposite to each other. By arranging the clamping structure 22 at one end of the plate body 21 and arranging the positioning structure 23 at the other end of the plate body 21, the plate body 21 can be stably arranged on the bottom shell 11 by fixing the two ends of the plate body 21.

[0028] By adopting the technical solution provided in this embodiment, one end of the plate body 21 smoothly transitions with the bottom shell 11 of the indoor unit housing 10, and the other end of the plate body 21 is covered on at least part of the indoor unit housing 10, so that the other end of the plate body 21 protrudes from at least part of the indoor unit housing 10, so that there is no need to set an additional buckle. The user only needs to use his hand to grab the other end of the plate body 21 and act on the plate body 21, so that the positioning structure 23 of the plate body 21 falls off from the positioning part of the indoor unit housing 10, and the opening process of the screw cover plate 20 can be completed. Therefore, by adopting the screw cover plate 20 provided in this embodiment, it is convenient for users to operate and improve the efficiency of disassembly and assembly.

[0029] Specifically, a clamping groove 111 is provided on the bottom shell 11 of the indoor unit housing 10 in this embodiment. The clamping portion 221 includes a first clamping strip 2211 and a second clamping strip 2212, the first clamping strip 2211 and the second clamping strip 2212 are arranged at intervals, and the first clamping strip 2211 and the second clamping strip 2212 are both used to abut against the inner wall of the clamping groove 111. Specifically, the side wall of the first clamping strip 2211 away from the second clamping strip 2212 and the side wall of the second clamping strip 2212 away from the first clamping strip 2211 are both used to abut against the inner wall of the clamping groove 111 to achieve clamping cooperation, so that one end of the plate body 21 can be movably clamped in the clamping groove 111 through the first clamping strip 2211 and the second clamping strip 2212.

[0030] In this embodiment, the abutment portion 222 includes a first abutment block 2221, which protrudes from the first clamping strip 2211 and is used to abut against the side wall of the clamping slot 111 to prevent the first clamping strip 2211 from falling off from the clamping slot 111 through the first abutment block 2221.

[0031] In this embodiment, the abutment portion 222 also includes a second abutment block 2222, which protrudes from the second clamping strip 2212 and is used to abut against the side wall of the clamping slot 111 to prevent the second clamping strip 2212 from falling off from the clamping slot 111 through the second abutment block 2222.

[0032] Specifically, the first abutting block 2221 is provided with a first abutting inclined surface 22211, and the distance between the first abutting inclined surface 22211 and the side wall of the first clamping strip 2211 gradually decreases in the direction from the first clamping strip 2211 to the first abutting block 2221. With such a configuration, it is convenient to slide the first clamping strip 2211 into the clamping groove 111 during the clamping process of the clamping portion 221 and the clamping groove 111. Specifically, the first abutting block 2221 can be a triangular prism structure, one of the side surfaces of the triangular prism is the first abutting inclined surface 22211, and the other side surface connected to the first abutting inclined surface 22211 can be used to abut against the side wall of the clamping groove 111 of the bottom shell 11.

[0033] Specifically, the second abutting block 2222 is provided with a second abutting inclined surface 22221, and the distance between the second abutting inclined surface 22221 and the side wall of the second clamping strip 2212 gradually decreases in the direction from the second clamping strip 2212 to the second abutting block 2222. With such a configuration, it is convenient to slide the second clamping strip 2212 into the clamping groove 111 during the clamping process of the clamping portion 221 and the clamping groove 111. Specifically, the second abutting block 2222 can be a triangular prism structure, one side of the triangular prism is the second abutting inclined surface 22221, and the other side connected to the second abutting inclined surface 22221 can be used to abut against the side wall of the clamping groove 111 of the bottom shell 11.

[0034] Specifically, the height of the first clamping strip 2211 can be h1≥6mm; or the height of the second clamping strip 2212 can be h2≥6mm; or the height of the first clamping strip 2211 can be h1≥6mm, and the height of the second clamping strip 2212 can be h2≥6mm.

[0035] In this embodiment, the height of the first clamping strip 2211 can be h1≥6mm, and the height of the second clamping strip 2212 can be h2≥6mm. With such a configuration, the elasticity of the first clamping strip 2211 and the elasticity of the second clamping strip 2212 can be improved, so that the first clamping strip 2211 and the second clamping strip 2212 can be easily inserted into the clamping groove 111. Specifically, the first clamping strip 2211 and the second clamping strip 2212 can both be made of plastic material.

[0036] In order to better prevent the first abutting block 2221 from falling off from the clamping groove 111, the height of the first abutting block 2221 protruding from the first clamping strip 2211 in this embodiment is h3, and h3 ≥ 0.5mm, so as to improve the stability of the setting. Specifically, h3 here refers to the distance between the farthest point where the first abutting block 2221 protrudes from the first clamping strip 2211 and the side wall of the first clamping strip 2211 away from the second clamping strip 2212, so that when the first abutting block 2221 abuts against the side wall of the clamping groove 111, the abutting distance is guaranteed to be no less than 0.5mm, thereby further ensuring the stability of the setting.

[0037] In order to better prevent the second abutting block 2222 from falling off from the clamping groove 111, the height of the second abutting block 2222 protruding from the second clamping strip 2212 in this embodiment is h4, and h4 ≥ 0.5mm, so as to improve the stability of the setting. Specifically, h4 here refers to the distance between the farthest point where the second abutting block 2222 protrudes from the second clamping strip 2212 and the side wall of the second clamping strip 2212 away from the first clamping strip 2211, so that when the second abutting block 2222 abuts against the side wall of the clamping groove 111, the abutting distance is guaranteed to be not less than 0.5mm, thereby further improving the stability of the setting.

[0038] Specifically, the positioning structure 23 in this embodiment is a positioning protrusion, which is adapted to the positioning groove 112 on the bottom shell 11 (the positioning groove 112 is the positioning structure 23 on the bottom shell 11) so that the other end of the plate body 21 can be positioned by the cooperation of the positioning protrusion and the positioning groove 112 to improve the setting stability of the screw cover plate 20 on the indoor unit casing 10.

[0039] Alternatively, the positioning structure 23 may be interference-fitted with the inner wall surface of the bottom shell 11 .

[0040] In this embodiment, there are multiple positioning protrusions, which are arranged at intervals on the side of the plate body 21, so that the positioning is performed by the multiple positioning protrusions and the positioning grooves 112. Such an arrangement can further improve the stability of the arrangement.

[0041] Specifically, two sections of positioning grooves 112 are provided on the bottom shell 11 , and correspondingly, positioning protrusions are relatively provided on both sides of the plate body 21 , so that the plate body 21 can be limited by the positioning protrusions on both sides at the same time, so as to better improve the stability of the setting.

[0042] In order to facilitate the positioning protrusion to slide into the positioning groove 112, in this embodiment, a guide slope 231 is provided on the positioning protrusion to guide the positioning protrusion into the positioning groove 112 through the guide slope 231. Specifically, the matching clearance between the guide slope 231 and the positioning groove 112 can be about 0.1 mm, so that the screw 30 cover can be prevented from loosening.

[0043] Specifically, the board body 21 in this embodiment includes a main board, a first side board and a second side board. The first side board and the second side board are relatively arranged on both sides of the main board. One positioning protrusion is arranged on the first side board, and the other positioning protrusion is arranged on the second side board.

[0044] When disassembling the screw cover plate 20 provided in this embodiment, the clamping structure 22 of the screw cover plate 20 is first pressed inward to disengage the first abutting block 2221 and the second abutting block 2222 from the side wall of the clamping groove 111, so that the outer surface of the screw cover plate 20 can be easily lowered, so that there is a slight gap between the front end of the screw cover plate 20 and the decorative plate 12, and then the screw cover plate 20 is manually moved clockwise to make the positioning protrusion fall off from the positioning groove 112, and the clamping structure 22 of the screw cover plate 20 slides along the rib 113 on the bottom shell 11 until the screw cover plate 20 is opened to the maximum position. When the screw cover plate 20 is opened to the maximum position, due to the abutment of the first abutting block 2221 and the second abutting block 2222, the screw cover plate 20 will not fall off from the clamping groove 111, which is convenient for the operator to drive the screw 30. Therefore, by providing a snap-fit ​​structure 22 at one end and a positioning structure 23 at the other end, it is possible to prevent the screw cover 20 from falling off when opened, which makes it difficult to install the screw cover 30.

[0045] Embodiment 2 of the present invention provides an air conditioner indoor unit, which includes an indoor unit housing 10 and a screw cover plate 20. The screw cover plate 20 is arranged on the indoor unit housing 10, and the screw cover plate 20 is the screw cover plate 20 provided in embodiment 1.

[0046] Specifically, the bottom shell 11 in this embodiment is also provided with a plurality of ribs 113, wherein two ribs 113 are arranged at intervals, and the two ribs 113 arranged at intervals are used to form a snap-in groove 111. The indoor unit housing 10 in this embodiment also includes a decorative plate 12 and a panel body 13, and the panel body 13 is arranged on the outside of the decorative plate 12. The decorative plate 12 and the panel body 13 are pre-assembled together first, and then the connection between the decorative plate 12 and the panel body 13 is installed on the bottom shell 11 by screws 30, so as to complete the installation of the indoor unit housing 10. One end of the screw cover plate 20 is movably arranged on the bottom shell 11, and the other end of the screw cover plate 20 is positioned by the positioning joint and the positioning groove 112, and the other end of the screw cover plate 20 is covered on the decorative plate 12.
