Specifically, the casing 100 has an air inlet and an air outlet 101, and the air outlet 101 penetrates through a front side wall of the casing 100 in the front-rear direction, for example. Fan assembly 200 is established in casing 100, for example, fan assembly 200 includes first fan, second fan and motor, and the motor is connected with first fan and second fan transmission respectively in order to drive first fan and second fan and rotate, and the air-out end of first fan and the air-out end of second fan set up towards air outlet 101 respectively. The indoor heat exchanger 300 is disposed in the casing 100, and the indoor heat exchanger 300 is located between the air outlet 101 and the fan assembly 200. Indoor air flow enters the interior of the cabinet 100 through the air inlet to exchange heat, and then is conveyed to the indoor space through the air outlet 101.

The humidifying assembly 400 is disposed in the cabinet 100, the humidifying assembly 400 is located on a side of the indoor heat exchanger 300 facing the air outlet 101, for example, the humidifying assembly 400 is located on a front side of the indoor heat exchanger 300, and the humidifying assembly 400 has a steam inlet 401 and an exhaust port 402. The steam enters the humidifying assembly 400 through the steam inlet 401, is sprayed into the cabinet 100 through the spraying port 402, and is finally delivered to the indoor space along with the airflow through the air outlet 101.

The water pan 500 is disposed in the cabinet 100, and the water pan 500 is located below the indoor heat exchanger 300. The horizontal projection of the humidifying assembly 400 is at least partially located within the horizontal projection of the water collector 500, that is, the horizontal projection of the humidifying assembly 400 is partially or completely located within the horizontal projection of the water collector 500. In this way, the condensed water generated by the humidifying assembly 400 can be prevented from flowing out of the water receiving tray 500 to soak the ceiling or floor of the user.

Therefore, according to the air-conditioning indoor unit 10 provided by the embodiment of the present invention, uninterrupted humidification can be performed in modes such as cooling, heating or air supply, so as to realize dual control of temperature and humidity, and provide better comfort; moreover, the humidifying assembly 400 is located on one side of the indoor heat exchanger 300 facing the air outlet 101, so that the assembly and the maintenance are easy, and the condensation of steam on the indoor heat exchanger 300 is avoided; in addition, by dropping the projection of the humidifying assembly 400 partially or entirely into the drip tray 500, the dew may be prevented from soaking the ceiling or the floor.
