Detailed ways

The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention proposes an embodiment of an air-conditioning indoor unit, as shown in FIGS. , the housing in this embodiment is formed by an integrally formed casing, a left side panel, a right side panel and a panel. During production, the casing, the left side panel, the right side panel and the panel are molded by one-time injection molding to realize the integration of the casing 1, which is connected with the casing 1 in the prior art through multiple pieces. Compared with the structure of the air conditioner, it simplifies the structure of the entire air-conditioning shell, reduces the number of parts that make up the shell, and directly molds it at one time, which reduces the production cost. It is not necessary to connect and fix every two adjacent parts, which simplifies the installation. The operation steps improve the assembly efficiency; at the same time, since the connection between the two parts of the shell will inevitably have the problems of surface difference, color difference and level difference, the integrally formed shell in this embodiment will not have a connection transition phenomenon, which effectively solves the problems of surface difference, step difference and color difference in the casing of the existing air-conditioning indoor unit, and enhances the overall aesthetics.

An installation cavity 2 located inside the casing 1 can be formed, and the casing 1 is provided with an air outlet 3. Specifically, the air outlet 3 in this embodiment is arranged at the front end of the casing 1. An air inlet 4 is arranged on the side opposite to the air outlet 3 on the casing 1, the air inlet 4 is arranged at the rear end of the casing 1, and a channel for circulating air can be formed between the air outlet 3, and the skeleton 5 is arranged on the The inside of the installation cavity 2 is locked and fixed with the housing 1 through the locking structure 6 . When the housing 1 in this embodiment is assembled with the framework 5, the corresponding end of the air outlet 3 of the housing 1, that is, the front end and the framework 5 are fixed by buckles and screws, and the rear end of the housing 1 is connected to the housing by a clamping structure. 1 is fixed, since the shell 1 in this embodiment adopts an integrally formed structure, the connection between the frame 5 and the left side plate and the right side plate can be simplified, and the frame 5 and the shell 1 are only fixed through the front end and the rear end It only needs to be connected, which simplifies the installation operation steps and improves the assembly efficiency. At the same time, since the housing 1 in this embodiment is an integrated structure, it cannot be connected to the frame 5 by means of multiple screws in the prior art during assembly. In this embodiment, a detachable card is proposed. The connection structure 6 realizes the fast and convenient disassembly and installation of the housing 1.

Further, the buckle 62 includes a buckle body 621 and a toggle arm 622 extending upward from the buckle body 621 , a section between one end of the buckle body 621 and the toggle arm 622 can be The clamping part 621-1 that fits into the clamping groove 61 can be any one of the two ends of the clamping body 621, and there is no limitation here. A guide surface 623 is provided.

Preferably, the card slot 61 includes a first card slot 611 and a second card slot 612 that cooperate with the card fitting part 621-1, and the frame 5 is provided with an engaging step, and the engaging step includes a side wall 51 and a bottom wall 52. When opening, the first card slot 611 is opened on the side wall 51, and the second card slot 612 is opened on the bottom wall 52 and communicates with the first card slot 611. It is further preferred that the second card slot 612 is vertical Both are arranged in the first card slot 611 to form an L-shaped card slot.

When assembling, insert the clamping part 621-1 of the buckle 62 into the first clamping groove 611, and press the bottom surface against the skeleton surface corresponding to the surface where the second clamping groove 612 is located, that is, the bottom wall 52 of the skeleton 5 superior. The top and bottom walls 52 of the first card slot 611 and the frame 5 realize the upper and lower positioning and fixing of the buckle 62, and realize the left and right positioning of the buckle 62 through the two side walls of the first card slot 611. , it can be inserted along the guide of the guide surface 623 of the clamping part 621-1, which is convenient and labor-saving, and can be quickly assembled and fixed. upper, to achieve resistance to the left and right, to prevent the buckle 62 from being too much inserted into the first slot 611, and to realize the limit of the insertion length of the buckle 62; The boom 622 uses an outward force to make the buckle 62 fall off from the frame 4, and at the same time, under the action of an external force, the guide surface of the clip 62 fits the side wall of the frame 5 and slides downward, finally realizing the clipping with the frame 5. The disengagement of the slot, by providing a second slot 612 connected with the first slot 611 and adopting a communication setting with the first slot 611, can provide an avoidance space for the buckle 62 when the buckle 62 is disassembled, so as to facilitate the buckle 62 After being stressed, it slides downwards and breaks away from the frame 5.

Further, the buckle body 621 is a horizontal plate, the toggle arm 622 is a vertical plate set perpendicular to the horizontal plate, the two form a T-shaped buckle structure, and the guide surface 623 is set on The inclined surface or the curved surface on the horizontal plate.

Further, the air inlet 4 is provided with an air inlet grill 7 , preferably, the air inlet grill 7 is arranged at the rear of the housing 1 . The inlet grill 7 is provided with a dust filter integrally injection-molded with it, and the inlet grill 7 is detachably arranged on the housing 1 . The air inlet grille 7 and the dust filter adopt an integrated design. When cleaning the dust filter, the air inlet grille 7 can be disassembled for cleaning, and the operation is simple and convenient.
