Preferably, an air guiding structure is further disposed on the inner annular surface 121 and/or the outer annular surface 122, and the air guiding structure is configured to gradually reduce the width of the air outlet at the air outlet. For example, the wind guiding structure adopts two arc plates as shown in fig. 3A or 3B, and the arrangement of the two arc plates gradually narrows the outlet widths of the first air outlet 123 and the second air outlet 124, so that when the air flow passes through the air outlet, a venturi effect is generated to accelerate the flow velocity, thereby realizing the spraying effect. When the air is sprayed, negative pressure is generated near the annular air outlet, and the negative pressure can attract air near the annular air outlet to flow together, so that the circulation of indoor air is realized, and the air supply quantity is effectively improved. Of course, the air guiding structure may also be any other arrangement manner as long as the arrangement manner can gradually narrow the air outlet width of the first air outlet 123 and/or the second air outlet 124, and details are not repeated herein.

The spraying mode can realize the spraying air-out effect, the spraying range is far, and the air outlet quantity is larger; the diffusion mode is that the second air outlet 124 supplies air to two sides, the air supply area is wide, airflow can be formed indoors in an encircling mode, and circulation of indoor air is enhanced. In addition, the arrangement of the annular air outlet structure 12 enables the structure of the indoor unit of the air conditioner to be novel, the iterative sealing idea of the traditional cabinet machine product is overturned, and the development and the revolution of the air conditioner are promoted. Through the bottom with water tank 21 fixed connection at interior annular surface 121 for the water smoke after the atomizer 22 atomizing can be directly sent to indoor each corner with the air current mixture of air outlet exhaust, guarantees the humidification effect, with the travelling comfort that improves indoorly.
