Or, the first fan part 60 and the second fan part 70 are in working state at the same time.

Wherein, both the first fan part 60 and the second fan part 70 can realize forward rotation and reverse rotation. That is, the first blower part 60 and the second blower part 70 can rotate clockwise, and can also realize counterclockwise rotation. Such setting can increase the air outlet efficiency and air inlet efficiency of the indoor unit by controlling the rotation mode of the fan part.

The indoor unit in the above embodiments can also be used in the technical field of air conditioners, that is, according to another aspect of the present invention, an air conditioner is provided. The air conditioner includes an indoor unit, which is the indoor unit in the above embodiments.

Specifically, the air conditioner has the air supply modes of the upper air outlet and the lower air outlet. At the same time, the volute tongue at the air inlet is rotated to increase the air intake area, increase the air intake volume of the air conditioner, and improve the performance of the air conditioner. The user can choose the upper air outlet or the lower air outlet according to the needs, and at the same time rotate the volute tongue at the air inlet according to the upper air outlet or the lower air outlet mode 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 intake area can be increased, which helps to improve the performance of the air conditioner. At the same time, the up and down air outlet method is beneficial to improve the uniformity of room temperature distribution and 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, the second volute tongue can rotate around the center of rotation, and the upper and lower cross-flow fan blades are respectively arranged at the upper and lower sides of the heat exchanger of the indoor unit. When the wind needs to be discharged from the upper air outlet, the second volute tongue rotates counterclockwise around the rotation center, the air enters from the lower air outlet, and is blown out from the upper air outlet after heat exchange by the evaporator. When the air needs to be discharged from the lower air outlet, the first volute tongue rotates The center rotates clockwise, the airflow enters from the upper air outlet, and blows out from the lower air outlet after heat exchange by the evaporator.

When the air conditioner is in an off state, as shown in FIG. 2 , the first volute tongue rotates counterclockwise around the rotation center to the closed position, and the second volute tongue rotates clockwise around the rotation center to the closed position. The first volute tongue and the second volute tongue can isolate the dust from entering the interior of the air conditioner at this time, and cooperate with the wind deflector to ensure that the interior of the air conditioner is clean when it is turned off.

When the air conditioner is cooling, as shown in Figure 3, the upper cross-flow fan blades are in operation, and the lower cross-flow fan blades are not in operation. The first volute tongue rotates clockwise around the center of rotation to the open position, the second volute tongue rotates counterclockwise around the center of rotation to the open position, the air inlet area of the lower air outlet increases, the airflow enters from the lower air outlet, passes through the evaporator after heat exchange from the upper The wind blows out. The first volute tongue also plays the role of extending the air duct, the wind speed of the upper air outlet is higher, and the airflow can blow out a longer distance. Compared with ordinary air conditioners, this air conditioner has a larger air intake, higher upper air outlet position, better air conditioner performance, better shower air supply effect, better air conditioner cooling effect, and more uniform temperature drop.

When the air conditioner is heating, as shown in Figure 4, the lower cross-flow fan blade operates, and the upper cross-flow fan blade does not operate. The first volute rotates clockwise around the center of rotation to the open position, the second volute rotates counterclockwise around the center of rotation to the open position, the air inlet area of the upper air inlet increases, the air enters from the upper air outlet, passes through the evaporator and flows from the lower Blowing out from the air outlet, the second volute tongue also plays the role of extending the air duct. The wind speed of the lower air outlet is higher, and the airflow can blow out a longer distance. Compared with ordinary air conditioners, this 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.
