본 발명의 양방향 블로워(1)는 내부공간의 공기 흐름이 유도되는 전 둘레 스크롤의 길이를 공기 토출이 이루어지는 출구단으로 확장해 주는 스크롤 리브(20), 예각의 입구각과 둔간의 출구각을 갖는 블레이드(3)가 내부공간으로 외부 공기를 흡입해주는 팬(5)을 구비한 블로워 바디(2)로 구성됨으로써 통풍시트(100)에 적합한 풍량 성능을 높이면서도 와류 발생 저지로 작동 소음을 낮추는 특징이 구현된다.

    A bidirectional blower may include a blower body having a scroll rib making a length of an entire perimeter scroll guiding air flow in an internal space to an outlet end portion where air discharge is performed, and a fan in which a blade having an inlet angle of an acute angle and an outlet angle of an obtuse angle draws external air into the internal air, thereby realizing the characteristics of lowering an operating noise by preventing a generation of vortex while enhancing air volume performance suitable for a ventilation seat.
