Abstract
본 발명은 에어콘의 소음감소장치에 관한 것으로서, 특히 블로어팬과, 상기 블로어팬과 일정간격 떨어진 스데빌라이져를 구비하는 에어콘에 있어서, 블로어팬이 회전될때 각 블레이드가 스테빌라이져를 통과하면서 발생하는 소음과 위상이 반대인 음을 발생시켜 서로 상쇄하는 소음상쇄수단을 구비하는 특징적인 구성에 의해, 특이음을 근본적으로 해결할 수 있을 뿐만 아니라 그로 인한 다른 소음의 중대나 효율의 저하를 가져오지 않는다. 또한 특이음 때문에 블로어팬의 설계시 제한되어왔던 스데빌라이져와 블로어팬과의 상대적인 위치및 형상설계가 자유로워져 블로어팬의 성능향상에 효과적인 것이다.
