The humidification water tank 2 also expands the humidification function of the hanging angle air conditioner. In addition, the setting position of the humidification water tank 2 also makes the airflow after the heat exchange between the blower fan 4 and the heat exchanger 3 flow through the humidification water tank 2. The temperature of the airflow is adjusted so as to achieve the purpose of soft airflow and prevent the airflow from being too cold or overheating and affecting the user experience. By arranging the impeller group 42 of the cross-flow fan to be able to expand and contract along the axial direction of the first driving motor 41, the hanging angle air conditioner indoor unit of the present invention can also realize the control of the vertical air outlet height, according to the actual installation position of the air conditioner and the user The height parameters are adjusted to achieve the effect of not blowing the head up and down the legs, further improving the user experience.
