Abstract

The invention discloses a fresh air device and an air conditioner with the same. The fresh air device comprises: a volute assembly, wherein the volute assembly is provided with a mounting cavity and a volute air inlet communicating with the mounting cavity; a sealing cover, wherein the sealing cover is arranged on one side of the volute assembly in a covering mode, the sealing cover and the volute assembly are matched to form an air inlet cavity, and the air inlet cavity communicates with the mounting cavity through the volute air inlet; and a filter screen assembly, wherein the filter screen assembly is arranged in the air inlet cavity and located at the volute air inlet. The filter screen assembly comprises a filter screen and a fixing frame for fixing the filter screen, wherein a silencing side wall is arranged on the fixing frame, a first micropore structure is arranged on the silencing side wall, and the silencing side wall is matched with the volute assembly and the sealing cover to form a silencing cavity. A noise reduction structure is arranged on the fixing frame of the fresh air filter screen and is integrally formed through injection molding, additional parts and installation procedures do not need to be added, and the production cost is reduced.

Description

technical field [0001] The invention relates to the related technical field of fresh air air conditioners, in particular to a fresh air device and an air conditioner equipped with the same. Background technique [0002] At present, as people pay more attention to a healthy home environment, more and more air conditioners have begun to add health functions, and fresh air is one of the most important ones. However, due to the limitation of the installation conditions of the air conditioner, the diameter of the fresh air pipe of the fresh air conditioner is generally small. Under the condition of a large fresh air volume, the wind speed in the fresh air pipe will be very fast, and the friction between the air and the pipe wall will produce harsh noise. As the fresh air duct is introduced into the room, it will affect the user experience. [0003] Existing air conditioners often use a separate noise reduction structure for noise reduction, such as installing the noise reduction...
