For example, as shown in fig. 4, in the first cooling mode, the third air deflector is controlled to swing to a first set angle, so that the lower air outlet 114 is inclined upward to discharge air, and the cool air in the room moves downward, so that the temperature gradient at each position in the room is smaller. The first setting angle is set to be 10-80 degrees.

For example, as shown in fig. 3, in the heating mode, the third air deflector is controlled to swing to the second set angle, so that the lower air outlet 114 is inclined downward to discharge air, and the indoor hot air moves upward, so that the temperature gradient at each indoor position is smaller, the lower part of the user's lower leg is more easily heated, and the experience of warm air is better. The second setting angle is set to be 100-170 degrees.

For example, as shown in fig. 3, in the heating mode, the electric heating device 150 may be turned on to perform rapid heating, so as to improve the heating efficiency of the air conditioner.
