Specifically, the second side wall 22 may be a second planar structure, and the second planar structure is inclined from the vertical direction. With this arrangement, it is better facilitated to direct the wind in the room along the edge of the second side wall 22 to the curved structure at the top.

Specifically, the second sidewall 22 may alternatively be a curved structure. With this arrangement, it is possible to facilitate adjustment of the configuration of the indoor unit casing while facilitating the wind in the upper room to be directed along the edge of the second side wall 22 to the arc-shaped configuration of the ceiling.

In the present embodiment, the front panel 20 has a first end and a second end opposite to each other, and the first end is located at the air inlet 30. The distance between the first side wall 21 and the second side wall 22 gradually decreases along the extending direction from the first end to the second end. By adopting the arrangement, the air flow passing through the arc-shaped structure can be conveniently and better enabled to enter the interior of the indoor unit shell along the first side wall 21, the inlet area of the whole unit is fully utilized, meanwhile, the vortex in the front panel 20 disappears, the noise generated by the vortex is reduced, the air volume of the whole unit is effectively improved, and the air volume and the comfort of the whole unit are improved.

The second embodiment of the invention provides an air conditioner indoor unit, which comprises an indoor unit shell, wherein the indoor unit shell is the indoor unit shell provided in the first embodiment.
