Description

technical field

[0001] The invention belongs to the technical field of air conditioning, in particular to an air conditioning indoor unit. Background technique

[0002] The indoor units of the existing wall-mounted air conditioners are all strip-shaped, and use a cross-flow fan and a bent evaporator for air supply. The air after heat exchange of the bent evaporator is directly blown out from the air outlet under the action of the internal cross-flow fan, and all the air blown out is heat exchange air. One disadvantage of this kind of air supply is that the air sent out is all heat exchange air, the air volume is small, and the indoor air circulation speed is slow; another disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air blown out The wind blows directly on the user, and the user feels uncomfortable. In addition, because the indoor units of the existing wall-mounted air conditioners are elongated, they are not only bulky...
