In the prior art, when the air conditioner is in a cooling state, the cold air blown out is not soft enough, and the comfort level is not good. For example, the existing ceiling air conditioner is usually installed on the top of a room and located above the human activity area. When the air conditioner is in a cooling state, the air coming from the circular air inlet passes through the heat exchanger and is blown out directly from the air outlet, forming a waterfall of cold air. The waterfall of cold air is very comfortable for people with strong resistance and high body temperature, but it is not soft enough for people with weak resistance such as the elderly and children, and the comfort level is not good.
