Referring to fig. 3 and 4, the indoor unit 100 may further include a plurality of air deflectors 180 disposed at the outlet 122 and distributed along a length direction of the outlet 122 to adjust a flow direction of the airflow. That is, the plurality of air deflectors 180 are distributed in the lateral direction (i.e., the left-right direction) of the indoor unit 100.
The included angle between the rotation axis of each air deflector 180 and the length direction of the air outlet 122 is larger than 0 degree, so that the air outlet 122 is divided into a plurality of air outlet areas, and the air flow guided out by each air deflector 180 at least partially flows through the outer side wall surface of the adjacent air deflector 180, thereby preventing the cold and hot air flows from intersecting at the outer side wall surface of the air deflector 180 in a refrigeration state and forming condensed water to pollute the indoor environment.

Further, each of the air deflectors 180 may be substantially parallelogram-shaped to reduce an area of the air outlet 122 that is not closed when the plurality of air deflectors 180 are in the closed state.
In the present invention, the air outlet 122 may be arranged to extend obliquely upward from back to front, that is, the direction of the air outlet 122 may be inclined downward, so as to enable the guided air flow to flow obliquely upward, and while increasing the adjustment range of the air deflector 180 to the air flow direction, the air flow is prevented from blowing directly onto the human body in the refrigeration state, so as to achieve the refrigeration effect of being cool but not cold, and reduce the risk that the cold and hot air flows converge on the panel 130 to form condensed water. The air outlet 122 may be oriented directly in front of and directly below.
In some embodiments, the angle between the rotation axis of each air deflector 180 and the length direction of the air outlet 122 may be 90 °, so that the air deflector 180 only adjusts the flow direction of the air flow in the transverse direction of the indoor unit 100.

In some further embodiments, the plurality of air deflectors 180 may be arranged such that the opening angle of the plurality of air deflectors 180 is gradually decreased along the air guiding direction when the plurality of air deflectors 180 are in the open state, so that the air flow guided out by the air deflector 180 located downstream in the air guiding direction in two adjacent air deflectors 180 is utilized to drive the air flow guided out by the air deflector 180 located upstream in the air guiding direction to flow along the air guiding direction while the air supply range is increased, thereby increasing the air supply amount of the indoor unit 100 as a whole and improving the cooling and heating efficiency.
In other embodiments, the indoor unit 100 may include one motor 190 and one link connecting the plurality of air deflectors 180. Both of the pivoting portions 182 of the plurality of air deflectors 180 may be configured to be rotatably coupled to the housing, and the motor 190 may be configured to be drivingly coupled to one of the pivoting portions 182 of one of the air deflectors 180.
