Abstract

The invention discloses a fresh air device and an air conditioner with the same. The fresh air device includes: a volute assembly, the volute assembly has an installation cavity, and the volute assembly is provided with a volute air inlet communicating with the installation cavity; a sealing cover, the sealing cover is arranged on one side of the volute assembly , and the sealing cover cooperates with the volute assembly to form an air inlet cavity, and the air inlet cavity communicates with the installation cavity through the volute air inlet; the filter screen assembly, the filter screen assembly is arranged in the air intake cavity and is located at the At the air inlet of the volute, the filter assembly includes: a filter screen and a fixing frame for fixing the filter screen; wherein: the fixing frame is provided with a sound-absorbing side wall, and the sound-absorbing side wall is provided with a first microporous structure , the sound-absorbing side wall cooperates with the volute assembly and the sealing cover to form a sound-absorbing chamber. In the present invention, the noise reduction structure is arranged on the fixing frame of the fresh air filter net, and injection molding is integrally formed, without adding additional parts and installation procedures, and reducing production costs.

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 having the same. Background technique [0002] At present, as people pay attention to a healthy home environment, more and more air conditioners begin to add health functions, and fresh air is one of them. However, due to the limitation of the installation conditions of the air conditioner, the diameter of the fresh air duct of the fresh air conditioner is generally small. Under the condition of large fresh air volume, the wind speed in the fresh air duct 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's experience. [0003] Existing air conditioners often use a separate noise reduction structure for noise reduction, such as setting the noise reduction structure at the air outlet of the fre...
