And when the difference value is smaller than or equal to a second preset difference value, determining that the air outlet mode of the air conditioner is a second side air outlet mode. The first preset difference is 2.5 degrees celsius to 4 degrees celsius, preferably 3 degrees celsius. The second preset difference is 0.6 degrees celsius to 1.5 degrees celsius, preferably 1 degree celsius.

In the second side air outlet mode and/or the first side air outlet mode, under the action of the air deflector 110, the air outlet between the upper edge of the air deflector 110 and the upper edge of the first air outlet 103 is larger than the air outlet between the lower edge of the air deflector 110 and the lower edge of the first air outlet 103.

For example, the air supply of the second air outlet 106 can be enabled to realize no wind sense, so that direct blowing of cool air is avoided, and the comfort of a user is improved, or the first air outlet 103 and the second air outlet 106 are simultaneously used for air outlet, so that the air outlet angle of the indoor unit of the air conditioner is increased, the air outlet range is also increased, and the refrigerating and heating speeds are improved. For example, when the air deflector 110 is opened by 10 °, most of the air is blown out through the second air outlet 106 due to the blocking of the first air outlet 103, so that the air deflector 110 can be cooled and blown flat without blowing people, the air outlet range is enlarged, the comfort of users is improved, and condensation at the positions of the air deflector 110 can be prevented. Particularly, the induced air device can perform secondary pressurization on the air flow entering the second air outlet 106, so that the air outlet speed of the second air outlet 106 is improved, and further the air outlet mode required by a user is met. When rapid refrigeration is required, the air deflector 110 can be opened at a larger angle, so that a large amount of heat exchange air flows out through the first air outlet 103, and rapid refrigeration is realized. At this time, the air flow speed can be further improved by opening the air inducing device.
