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.

    A bi-directional blower includes a blower body for guiding for air to flow along an entire circumference scroll shape of an inner space of the blower body. The blower body divides the inner space into an upward space and a downward space to guide air flow. The blower body comprises: an upper discharge case discharging the air flow along the entire circumference scroll shape toward the upward space through an upper discharge port; and a lower discharge case discharging the air flow along the entire circumference scroll shape toward the downward space through a lower discharge port.
