Description

Fresh air device and air conditioner with same Technical Field The application belongs to the technical field of household appliances, and particularly relates to a fresh air device and an air conditioner with the same. Background When the air conditioner is used for refrigerating or heating the indoor environment, the door and window is required to be closed to form a closed environment in the indoor environment, so that the heat exchange effect of the air conditioner on the indoor environment is guaranteed, but the indoor air quality is poorer and worse, and users can feel uncomfortable in the closed indoor environment for a long time. Therefore, more and more air conditioners are provided with a fresh air device, the fresh air device is generally arranged on an air conditioner indoor unit, and a pipeline communicated with the outside is arranged on the fresh air device, so that in the running process of the air conditioner indoor unit, outdoor fresh air can be introduced into the room by the fresh air device, and indoor dirty air is discharged, the heat exchange effect of the air conditioner indoor unit can be ensured, and the indoor air quality is improved.
