The application discloses an air conditioner indoor unit, and belongs to the technical field of air conditioners. The air conditioner indoor unit comprises a shell, an impeller, a heat exchanger, a volute and a volute tongue. The volute tongue and the shell form an air inlet air duct, and the volute and the volute tongue form an impeller mounting cavity and an air outlet air duct. The impeller is arranged at the impeller mounting cavity, and the impeller is used for driving airflow to sequentially pass through the air inlet air duct and the impeller mounting cavity to form outlet airflow. The outlet airflow comprises backflow airflow which flows back to the impeller after being divided at the volute tongue, and air outlet airflow which flows to the air outlet air duct. The air outlet airflow exchanges heat with the heat exchanger. A gap between a volute tongue windward surface of the volute tongue and the impeller forms a gap flow channel. A flow guide channel is arranged at the volute tongue, and the flow guide channel is used for guiding a part of the backflow airflow to the gap flow channel. The air conditioner indoor unit can improve the pressure resistance of the cross-flow fan.
