It can be understood that the reversing body 33 is rotatably disposed, so that the moving track of the reversing body 33 is circular, and the position of the reversing body 33 is always located in the circular track, so that the occupation of the reversing body 33 on the space in the moving process can be reduced, and the reversing body 33 and the reversing shell 31 can be distributed more compactly, so as to reduce the overall volume of the fresh air module and facilitate installation on the casing of the indoor unit of the air conditioner. The sub-chambers partitioned by the reversing body 33 into the airflow reversing chamber 310 form a communicating space communicating with the outlet airflow through-hole 315a and the indoor airflow through-hole 315c, or the outlet airflow through-hole and the outdoor airflow through-hole 315e, that is, the communicating space is formed by the matching and surrounding of the reversing body 33 and a part of the chamber walls of the airflow reversing chamber 310. So that the structure of the commutating body 33 can be simplified and the production raw materials required for its manufacture can be reduced, thereby reducing the manufacturing cost of the commutating body 33. Of course, the present application is not limited thereto, and in other embodiments, the reversing body 33 may be slidably disposed in the airflow reversing cavity 310, and a through-air channel is formed inside the airflow reversing cavity. At this time, when the direction changing body 33 slides between the outlet air flow passage 315a and the indoor air flow passage 315c, the air blown out from the outlet air flow passage 315a can flow into the air passage through one end of the direction changing body 33 close to the outlet air flow passage 315a, and flow into the indoor air flow passage 315c from the other end of the direction changing body 33. When the reversing body 33 slides between the outlet air flow passage 315a and the outdoor air flow passage 315e, the air blown out from the outlet air flow passage 315a can flow into the air passage through one end of the reversing body 33 close to the outlet air flow passage 315a, and flow into the outdoor air flow passage 315e from the other end of the reversing body 33.

Therefore, when the inlet airflow passing opening 311a is relatively large, the sub-chamber which is separated by the main body bottom plate 331 and communicated with the outlet airflow passing opening 315a and the indoor airflow passing opening 315c or the sub-chamber which is communicated with the outlet airflow passing opening 315a and the outdoor airflow passing opening 315e can be ensured to be closed. And at this moment, the air inlet volume can be increased by increasing the area of the air inlet flowing through the opening 311a, so that the working efficiency of the fresh air module can be improved. Further, the body bottom plate 331 and the body side plate 333 may be integrally formed, so that the strength of the connection between the two is improved, and the production efficiency is improved by integrally forming the two.

The arrangement of the motor mounting part 311c and the mounting part avoiding groove 331a provides a mounting space for the commutation motor 35, so that the main body bottom plate 331 and the commutation side plate 315 can be attached to each other, thereby ensuring the volume of the commutation housing 31 to be smaller. In order to facilitate maintenance and replacement of the reversing motor 35, the reversing motor 35 may be detachably fixed to the motor mounting portion 311c by a screw or a snap. In addition, it should be noted that, the present application is not limited to this, and in other embodiments, a knob exposed to the outside may be protruded from the main body bottom plate 331 of the reversing main body 33, and at this time, the main body bottom plate 331 of the reversing main body 33 may be driven to rotate by rotating the knob.
