As another optional embodiment, the controller of the indoor unit is configured to: receive a control instruction input by a user to represent the air supply mode; and control the air deflector assembly to adjust the air supply mode.

Here, the ventilation modes include, but are not limited to, a high-angle ventilation mode, a low-angle ventilation mode, a strong wind mode, and a weak wind mode.

In combination with the foregoing embodiments, when the air supply mode of the air conditioner is the high-angle mode or the strong wind mode, the lower air deflector 22 in the air deflector assembly is controlled to close the lower air outlet area, and the upper air deflector 21 opens the upper air outlet. Wind area, at this time, the middle wind deflector 23 is in the upper wind guide position, so that air can be blown into the indoor environment through the upper air outlet area;

The upper air deflector 21 can also adjust its own turning angle, so that the plate surface of the upper air deflector 21 is arranged in the horizontal direction or the oblique upward direction, so that the air outlet direction of the air flow is the horizontal air outlet or the oblique upward air outlet, so Airflow is not directed towards the user.

When the heat exchange mode of the air conditioner is the low-angle mode or the weak wind mode, the upper air deflector 21 in the air deflector assembly is controlled to close the upper air outlet area, and the lower air deflector 22 to open the lower air outlet area. The air deflector 23 is in the lower air guiding position, so that the air can be blown into the indoor environment through the lower air outlet area;

The lower air deflector 22 can also adjust its own turning angle, so that the plate surface of the lower air deflector 22 is arranged in the vertical direction, so that the air outlet direction is vertical downward air outlet.

The control modes of the air deflector and the air deflector assembly shown in the above-mentioned multiple embodiments to achieve different air supply effects can also be controlled by the controller.

The present invention also provides an air conditioner, the air conditioner has any one of the indoor units in the foregoing embodiments.

It should be understood that the present invention is not limited to the processes and structures that have been described above and shown in the accompanying drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
