It is isolated from the air outlet that does not let the air flow out, so as to prevent the air from flowing to the air outlet of the housing 1 that does not need to be air-out when the air conditioner is blowing air from above or below, thereby preventing cross-wind phenomenon. The other air deflector can block the useless air outlet of the upper air supply device or the lower air supply device, so as to prevent the air from flowing into the air outlet of the other air supply device when the air is out, causing air convection. phenomenon, thereby improving the air outlet efficiency.

Preferably, when the wind is blowing from the split floor-standing air conditioner, the first wind deflector 10 is at the first working position, the second wind deflector 11 is at the second working position, and the first wind deflector 10 and the second wind deflector 11 forms an air guide channel towards the first upper air outlet 4; when the split floor air conditioner blows air downward, the first air guide plate 10 is located at the second working position, the second air guide plate 11 is located at the first working position, and the second air guide plate 11 is located at the first working position.

A deflector 25 is also arranged between the heat exchanger 22 and the upper and lower air supply devices, and guide rings 3 are respectively arranged on the deflector 25 corresponding to the upper air supply device and the lower air supply device. The deflector 25 here has an integrated structure, and the two deflector rings 3 are all arranged on the deflector 25, and the air flow between the upper air supply device, the lower air supply device and the heat exchanger 22 passes through the deflector 25. The plates are separated, and the deflector 25 blocks the middle part of the upper air supply device and the lower air supply device and the air outlet side of the heat exchanger 22 at the same time, so that the air can only flow from the air guide after passing through the heat exchanger 22 for heat exchange. Circle 3 enters in the upper air supply device and the lower air supply device. Of course, the deflector 25 can also be configured as two independent plate bodies according to the setting positions of the upper air supply device and the lower air supply device, each plate body is provided with a guide ring 3, and each guide ring 3 Corresponding to a corresponding volute air inlet. The guide ring 3 can rectify the air entering the upper volute 12 and the lower volute 17 from the air inlet 2, reduce the occurrence of turbulence, improve the flow efficiency of the air, and then improve the air outlet efficiency of the air conditioner.

Of course, the above are preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the basic principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
