After the tuyere, the outdoor air is introduced into the fresh air device 100, then purified by the second purification module 132 in the fresh air device 100, and then passed through the fresh air inlet 112, and then vertically drawn through the first installation opening 1141 to be installed in the fresh air. After the first purification module 131 of the air outlet 113 is purified, the fresh air outlet 113 and the indoor fresh air outlet 210 enter the room, so as to provide fresh air for the room.

Or on the basis that the air conditioner is provided with an outdoor fresh air inlet and an indoor fresh air outlet 210, an indoor side air inlet 220 may also be provided;

The housing 200 is provided with an indoor side air inlet 220 ; the indoor side air inlet 220 communicates with the fresh air inlet 112 .

Wherein, the number of indoor side air inlets 220 is 1 and/or 2, which are arranged on the side surface of the lower part of the housing 200 of the air conditioner;

With this structure, after the outdoor air can be introduced into the room through the fresh air outlet 113 and the indoor fresh air outlet 210, since the indoor side air inlet 220 is connected with the fresh air inlet 112, then the indoor air enters the fresh air inlet through the indoor side air inlet 220. The air outlet 112, after being purified by the second purification module 132, introduces the purified indoor air into the fresh air device 100 through the fresh air inlet 112, and vertically pulls the first air outlet 113 provided in the fresh air outlet 113 through the first installation opening 1141. After the purification module 131 is purified, the fresh air outlet 113 and the indoor fresh air outlet 210 are introduced into the room again, so as to realize the circulation.

With this structure, the fresh air device 100 can not only purify the outdoor air, but also effectively purify the indoor air, thereby improving the quality of the indoor air and improving the user's comfort.

Other components in the air conditioner are all existing, and will not be repeated here.

Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be based on the scope defined by the claims.
