The rotation of the cross wind wheel 54 can drive the air in the cross wind channel 51 to flow, so that the air flows into the cross wind channel 51 from the air inlet 121 of the casing 10. The through-flow duct 51 may guide air in the through-flow scroll 53, and the air may flow in the extending direction of the through-flow duct 51. The through-flow air duct component 5 has the advantages of stable operation, uniform air outlet, small noise, simple structure and the like.

The air duct assembly 30 also has mutually isolated through-air outlet passages 52 and centrifugal air outlet passages 44. The through air outlet channel 52 and the centrifugal air outlet channel 44 are mutually independent, so that the mutual interference of air flows in the through air outlet channel 52 and the centrifugal air outlet channel 44 can be avoided, the uniformity of the air outlet air flow of the whole machine is ensured, and the noise is reduced.

When the air conditioner works, air can flow into the casing 10 from the air inlet 121 of the casing 10 under the action of the air duct assembly 30 and exchange heat with the heat exchanger component 20 in the casing 10, and a part of the air after heat exchange can flow into the through-flow air duct 51 under the drive of the through-flow wind wheel 54 and then flow into the through-flow air outlet channel 52, flows into the first air outlet 131 along the through-flow air outlet channel 52 and flows out of the casing 10 along the first air outlet 131 into a room.

The wind pressure in the centrifugal air duct 41 is larger than the wind pressure in the through-flow air duct 51, when the centrifugal air outlet channel 44 is communicated with the first air outlet 131 through the movement of the air door 47, the flow speed of the air flow mixed at the first air outlet 131 is faster than that of the air flow flowing out of the through-flow air outlet channel 52, so that the air flow diffusion distance is longer, the whole air supply distance is increased, and the indoor temperature adjusting efficiency of the air conditioner can be improved.

When the air door 47 cuts off the centrifugal air outlet channel 44 and the first air outlet 131, the air flow in the centrifugal air duct 41 flows into the centrifugal air outlet channel 44 under the driving of the centrifugal wind wheel 43, all the air flows in the centrifugal air outlet channel 44 flow out of the casing 10 along the second air outlet 151 above, and the air flow in the through-flow air duct 51 flows into the through-flow air outlet channel 52 under the driving of the through-flow wind wheel 54 and flows out of the casing 10 along the first air outlet 131.
