According to the present invention, in a dual scroll type bi-directional blower (1) applied to a ventilation seat (100), a blower duct (10) is connected to a chamfer and stairs type blower body (4, 4-1) having an internal space in which a blade (3) rotated with a motor (2) is accommodated for sucked air to be individually sent to a seat cushion (100-1) and a seat back (100-2) via the blower duct (10). Therefore, a chronic flow rate shortage and a noise generation phenomenon of the bi-directional blower can be improved with an enough scroll length in accordance with a whole circumferential dual scroll shape of the chamfer and stairs type blower body (4, 4-1).

    본 발명의 통풍시트(100)에 적용된 이중 스크롤 방식 양방향 블로워(1)는 모터(2)로 회전되는 블레이드(3)가 수용된 내부공간을 형성한 챔퍼(chamfer)/계단(Stairs)형 블로워 바디(4,4-1)로 블로워 덕트(10)를 연결하여 흡입 공기가 블로워 덕트(10)를 거쳐 시트 쿠션(100-1)과 시트 백(100-2)의 각각으로 보내줌으로써 챔퍼(chamfer)/계단(Stairs)형 블로워 바디(4,4-1)의 전 둘레 이중 스크롤 형상에 따른 충분한 스크롤 길이로 양방향 블로워의 고질적인 유량 부족과 소음발생 현상을 개선하는 특징이 있다.
