Accordingly, the outlet 22 can rotate within a rotation angle of 180 °, and the air supply range of the indoor air conditioner 100 can be further increased. For example, the outlet 22 rotates between a first position and a second position, the outlet 22 is vertically upward (refer to fig. 3) when the outlet 22 is located at the first position, and the outlet 22 is disposed downward (refer to fig. 4) when the outlet 22 is located at the second position.

The heat exchanger 5 has a heat exchange function with respect to the air flow entering the accommodating chamber 44 from the air inlet hole 43. For example, when the air conditioning indoor unit 100 starts the cooling mode, hot air in the room can enter the accommodating chamber 44 through the air inlet hole 43 and exchange heat with the heat exchanger 5 in the accommodating chamber 44, so as to reduce the temperature of the air flow, and further, cool air can be delivered to the room. When the air conditioning indoor unit 100 is in the heating mode, hot air in a room can enter the accommodating cavity 44 through the air inlet hole 43 and exchange heat with the heat exchanger 5 in the accommodating cavity 44, so that the temperature of the air flow is increased, and hot air flow can be conveyed to the room.
Preferably, as shown in fig. 12, the heat exchanger 5 is U-shaped. The U-shaped heat exchanger 5 has the advantages of large heat exchange area, simple and compact structure and high sealing performance, and meanwhile, the U-shaped heat exchanger 5 is convenient to overhaul and clean.
