According to the present invention, a bi-directional blower (1) comprises: a scroll rib (20) configured to expand a length of a full-circled scroll in which flow of the air in an inner space is induced to an outlet end from which the air is discharged; and a blower body (2) having a fan (5) in which a blade (3) with an acute-angled inlet angle and an obtuse-angled outlet angle enables outdoor air to be sucked into an inner space of the fan. Accordingly, air volume performance suitable for a ventilation sheet (100) can be increased, and generation of vortex can be prevented to reduce operation noise.

    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.
