The indoor unit in the above embodiment can also be used in the technical field of air conditioning equipment, that is, according to another aspect of the present application, an air conditioner is provided. The air conditioner includes an indoor unit, and the indoor unit is the indoor unit in the above-mentioned embodiment.

Specifically, the air conditioner has an air supply mode of air supply from the upper air outlet and air supply from the lower air outlet, and at the same time, the volute tongue at the rotating air inlet increases the air inlet area, increases the air inlet volume of the air conditioner, and improves the performance of the air conditioner. Users can choose to supply air from top or bottom according to their needs, and at the same time rotate the volute tongue at the air inlet according to the way of top or bottom air to increase the air inlet area.

By rotating the volute tongue at the air inlet and changing the position of the volute tongue, the air inlet area can be increased, which helps to improve the performance of the air conditioner. At the same time, the upper and lower air outlet methods are beneficial to improve the uniformity of the room temperature distribution and improve the comfort of the room.

Different air outlets can be selected according to cooling and heating to improve the comfort performance of the air conditioner.

As shown in Figure 1, the first volute tongue can rotate around the center of rotation, and the second volute tongue can rotate around the center of rotation. The upper cross-flow fan blades and the lower cross-flow fan blades are respectively arranged on the upper and lower sides of the heat exchanger of the indoor unit. When the wind needs to be discharged from the upper air vent, the second volute tongue rotates counterclockwise around the center of rotation. The airflow enters from the lower air vent, and blows out from the upper air vent after heat exchange through the evaporator. When the air needs to be discharged from the lower air vent, the first volute tongue rotates The center rotates clockwise, and the airflow enters from the upper air outlet, and blows out from the lower air outlet after heat exchange through the evaporator.

When the air conditioner is in the closed state, as shown in Figure 2, the first volute tongue rotates counterclockwise around the center of rotation to the closed position, and the second volute tongue rotates clockwise around the center of rotation to the closed position. The first volute tongue and the second volute tongue can isolate dust from entering the inside of the air conditioner at this time, and cooperate with the air deflector to ensure the cleanness of the inside when the air conditioner is closed.

When the air conditioner is refrigerated, as shown in Figure 3, the upper cross-flow fan blades operate, and the lower cross-flow fan blades do not operate. The first volute tongue rotates clockwise around the center of rotation to the open position, and the second volute tongue rotates counterclockwise around the center of rotation to the open position. The air inlet area of the downwind vent increases, and the airflow enters from the downwind vent. The tuyere blows out. The first volute tongue also functions to extend the air duct, and the wind speed from the upper air outlet is higher, and the airflow can blow out a longer distance. Compared with general air conditioners, this air conditioner has a larger air intake, a higher position of the upper air outlet, better performance of the air conditioner, better shower-style air supply effect, better cooling effect of the air conditioner, and more uniform temperature drop.

When the air conditioner is heating, as shown in Fig. 4, the lower cross-flow fan operates, and the upper cross-flow fan does not operate. The first volute tongue rotates clockwise around the center of rotation to the open position, and the second volute tongue rotates counterclockwise around the center of rotation to the open position. The air inlet area of the upwind vent increases, and the airflow enters from the upwind vent. When the tuyere blows out, the second volute tongue also functions to extend the air duct. The wind speed from the lower tuyere is higher, and the airflow can blow out a longer distance. Compared with general air conditioners, the air conditioner has a larger air intake, lower air outlet position, better performance of the air conditioner, better carpet air supply effect, better heating effect of the air conditioner, and more uniform temperature rise.
