[0042] In some embodiments of the present application, as shown in FIGS. 3, 9 and 10, the electric control assembly 2 includes an electric control box 21 and a limiting piece 22. The limiting piece 22 is arranged on the front side of the electric control box 21 in the front-back direction, and the second positioning structure is arranged on the limiting piece 22.

[0043] Therefore, the limiting piece 22 cooperates with the first positioning structure to limit the electric control assembly 2 in the up-down direction and the front-back direction of the air conditioner indoor unit 100. Meanwhile, by arranging the limiting piece 22 for cooperating with the first positioning structure, the limiting piece 22 can more quickly and accurately reach the predetermined position during the assembly of the electric control assembly 2 and the chassis 1, further improving the assembly efficiency, and the electric control box 21 and the limiting piece 22 can be produced respectively, improving the production efficiency.

At the same time, the clamping protrusion 221 is adapted to be clamped in the recessed part 11, which realizes the limiting of the electric control assembly 2 in the up-down direction, further ensures the pre-positioning of the electric control assembly 2, and improves the reliability. In addition, the clamping protrusion 221 protrudes towards the left side or the right side, so that the limiting piece 22 can be adapted to different models, improving the universality.

[0046] In some embodiments of the present application, as shown in FIG. 6, in the front-rear direction, the top wall of the recessed part 11 is inclined downward.

[0047] It can be understood that the clamping protrusion 221 enters the recessed part 11 in the front-rear direction. Thus, by setting the top wall of the recessed part 11 to be inclined downward in the front-rear direction, the top wall of the recessed part 11 plays a guiding role, thereby guiding the recessed part 11 to quickly and accurately extend into the recessed part 11, reducing the adjustment and correction time in the assembly process, avoiding assembly jam, thereby improving the assembly efficiency.

[0048] At the same time, in the front-rear direction, by inclining the top wall of the recessed part 11 downward, the clamping protrusion 221 is clamped in the recessed part 11, which further ensures the limiting of the electric control assembly 2 in the up-down direction, improving the reliability.

[0057] In some embodiments of the present application, as shown in FIGS. 3 and 12, the second positioning rib 131 is inclined downward in the front-back direction. It can be understood that the electronic control assembly 2 is assembled on the chassis 1 in the up-down direction. Therefore, in the front-back direction, the downward inclination of the second positioning rib 131 improves the limiting effect of the second positioning rib 131 on the electronic control assembly 2 in the left-right direction, and improves the reliability.

[0058] In the embodiments of the present application, the electronic control assembly 2 includes an electronic control box 21 and a limiting piece 22, and the second positioning rib 131 limits the electronic control box 21 in the left-right direction.
