An air conditioning indoor unit 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings, and the air conditioning indoor unit 100 may be an on-hook unit or a cabinet unit.

As shown in fig. 1 and 5, an air conditioning indoor unit 100 according to an embodiment of the present invention includes: the air conditioner comprises a chassis 1, a first support 21, a second support 22 and an air outlet assembly 3.

Specifically, as shown in fig. 2 and 5, the first support 21 is connected to one end (the left end shown in fig. 2) of the chassis 1 in the length direction, the second support 22 is connected to the other end (the right end shown in fig. 2) of the chassis 1 in the length direction, the air outlet assembly 3 includes an air outlet body 31, the air outlet body 31 is spaced apart from the chassis 1, one end (the left end shown in fig. 2) of the air outlet body 31 is rotatably connected to the first support 21, and the other end (the right end shown in fig. 2) of the air outlet body 31 is rotatably connected to the second support 22.
