[0027] like Figures 1 to 7 A middle frame assembly structure shown is used to assemble a panel 1 to a middle frame 2, wherein two hinges 11 and a plurality of first buckles 12 are provided on the back of the panel 1, wherein the two hinges 11 are respectively arranged on the left and right sides of the upper back of the panel 1, and a first clamping slot 111 is provided at the rear end of the hinge 11, wherein the opening of the first clamping slot 111 is arranged backward and inclined downward, and a plurality of first buckles 12 are arranged in a row at the lower part of the back of the panel 1; a rotating shaft 21 matching the first clamping slot 111 on the hinge 11 is respectively provided on the left and right sides of the middle frame 2, and a plurality of second clamping slots 22 matching the first clamping slots 12 are provided at the lower part of the middle frame 2; the first clamping slot 111 of the panel 1 is rotatably clamped on the rotating shaft 21 of the middle frame 2, and the plurality of first buckles 12 of the panel 1 are clamped in the rotating shaft 21 of the middle frame 2.

[0028] Unlike the conventional air conditioning panel and middle frame assembly structure in which the clips on the panel hinge are inserted into the slots on the middle frame, the present application opens a first slot 111 at the rear end of the hinge 11 of the panel 1 and provides a corresponding rotating shaft 21 on the middle frame 2, so that the panel 1 can be hung on the middle frame 2 like a hook. In this way, during the process of disassembling and assembling the panel 1, the first slot 111 of the hinge 11 and the rotating shaft 21 on the middle frame 2 do not need to be deformed.

[0029] After opening the panel 1, it is usually necessary to fix the panel 1 before inspecting the inside of the middle frame. Therefore, in the present invention, a third card slot 112 is provided on the movable leaf 11, and a second card buckle 23 is provided at the filter screen on the upper part of the middle frame 2. When the panel 1 rotates 90° around the rotating shaft 21, the second card buckle 23 of the middle frame 2 is inserted into the third card slot 112 of the panel 1 to fix the panel 1 and the middle frame 2. In this way, when the panel 1 needs to be fixed after opening the panel 1, the first card buckle 12 of the panel 1 is first disengaged from the middle frame 2, and then the panel 1 is rotated 90° along the rotating shaft of the middle frame 2, and the third card slot 112 in the movable leaf 11 is matched with the second card buckle 23 at the filter screen on the upper part of the middle frame 2 to be installed, thereby playing the role of supporting the panel.

[0030] In the present invention, considering that the first buckle 12 of the panel 1 is disengaged from the middle frame 2 and continues to rotate a certain angle due to inertia after disengagement, the angle between the first slot 111 and the vertical direction generally needs to be greater than 5°, considering that the hinge 11 interferes with the second buckle 23 on the middle frame 2, the angle between the first slot 111 and the vertical direction generally needs to be less than 70°, considering that during the production process, the air conditioner indoor unit equipped with the middle frame 2 is usually laid flat before installing the panel 1, in order to prevent assembly failure after the hinge 11 is installed, the larger the angle between the first slot 111 and the vertical direction, the better the effect. Therefore, in order to improve assembly reliability, in the present invention, the first slot 111 is set at 30° to 60° from the vertical direction.

[0031] A plurality of reinforcing ribs are provided at the connection between the rotating shaft 21 and the middle frame 2, thereby increasing the strength of the rotating shaft 21 on the middle frame 2 and preventing the rotating shaft 21 from deforming and breaking. A plurality of reinforcing ribs are provided on the hinge 11, thereby increasing the strength of the hinge 11 on the panel 1.
