In this embodiment, the first volute 21 of the air outlet duct 2, the inner panel 11 and the front water pan 61 enclose to form a closed diversion cavity, the inner panel 11 is provided with a communication port 111, the first volute 21 is provided with a through port 24, the communication port 111 enables the breeze cavity 16 to communicate with the diversion cavity, the through port 24 enables the air outlet duct 2 to communicate with the diversion cavity, the through port 24 communicates with the communication port 111 to form the diversion air duct 3, and the diversion air duct 3 communicates with the air outlet duct 2 and the breeze cavity 16.

The through hole 24 forms an airflow inlet of the breeze cavity 16, the first breeze opening 161 forms an airflow outlet of the breeze cavity 16, and the inner air deflector 7 is rotatably disposed at the through hole 24 for opening or closing the through hole 24.

When the inner wind deflector 7 rotates to close the through hole 24, it prevents the airflow in the wind outlet channel 2 from flowing into the breeze cavity 16 through the through hole 24, so as to prevent the airflow from flowing out of the first breeze opening 161. When the inner wind deflector 7 rotates to open the through hole 24, at least a part of the airflow in the wind outlet channel 2 is allowed to flow into the breeze cavity through the through hole 24, and then flows out through the first breeze opening 161. Through the arrangement of the rotation fit of the inner air guide plate 7 and the outer air guide plate 8, the breeze air supply effect without wind sensation is realized, and direct blowing users are avoided. Meanwhile, the opening and closing of the through hole 24 are realized by utilizing the difference of the rotating positions of the inner air guide plates 7, and the structure is simple and the operation is convenient.

In this embodiment, the through hole 24 is formed in the first volute 21, so that the airflow in the air outlet duct 2 enters the breeze cavity 16 through the through hole 24. When the internal air deflector 7 closes the through opening 24, the air flow in the air outlet duct 2 cannot flow to the air guide duct 3 under the blocking of the internal air deflector 7 in the process of flowing from back to front, so that the air flow is prevented from being blown out through the first micro-air opening 161. When the inner air deflector 7 opens the through opening 24, the inner air deflector 7 forces the airflow to flow to the through opening 24 in the air outlet duct 2, and the airflow in the air outlet duct 2 is guided.
