Abstract
본 발명은 양방향 구동용 원심 팬에 관한 것으로, 정방향회전 또는 역방향회전을 하는 팬의 날개를 팬의 회전방향에 따라 유동하게 하여 소음을 줄이고 효율을 증가시키고자 하는 고효율 저소음 양방향 구동용 원심 팬을 제공하는데 목적이 있는 본 발명은 구동용 원심 팬의 팬 본체(10) 중앙부에 형성된 팬 날개 지지부(20)의 외주연에 팬 날개(30)가 핀(24)결합되어 상기 원심 팬의 회전에 따라 괜 날개(30)가 소정의 각도로 회전되도록 구성되고, 상기 팬 날개 지지부(20)의 외주연상에 수개의 지지편(22)이 방사형으로 형성되고 상기 지지편(22)과 팬 본체(10) 사이에는 팬 날개(30)의 내측단부가 사입된 상태로 핀(24)에 관통결합 되어지며, 상기 팬 본체(10) 상면에는 소정각도로 일정간격을 가진 원호형상 안내홈(12)이 형성되고 팬 날개(30)의 하단에는 상기 안내홈(12)에 대응하는 위치로 안내돌기(32)가 형성되어 팬 날개(30)의 회전각도가 조정되어지도록 구성되는 양방향 구동용 팬에 의해 종래구동용 원심 팬의 정방향 회전과 역방향 회전시 같은 량의 유로저항과 풍량을 얻기위하여 수개의 팬날개가 팬 본체의 상면과 수직되게 형성되어 있기 때문에 팬 날개의 회전시 공기와의 마찰이 커서 팬이 소음도 커지고 냉각효율도 떨어지게 되는 문제점을 동시에 해결할 수 있는 효과적인 발명이다.The present invention relates to a centrifugal fan for two-way driving, to provide a highly efficient low-noise two-way centrifugal fan to reduce the noise and increase the efficiency by allowing the blade of the fan to rotate in the forward or reverse direction according to the rotation direction of the fan. The present invention has an object to the fan blade 30 is coupled to the pin 24 on the outer periphery of the fan blade support 20 formed in the center of the fan body 10 of the centrifugal fan for driving is fine according to the rotation of the centrifugal fan. The blade 30 is configured to rotate at a predetermined angle, and several support pieces 22 are radially formed on the outer circumference of the fan blade support 20, and between the support piece 22 and the fan body 10. In the inner end of the fan blade 30 is inserted into the pin 24 in the state inserted, the upper surface of the fan body 10 is formed with an arc-shaped guide groove 12 having a predetermined interval at a predetermined angle and the fan The guide at the bottom of the wing 30 A guide protrusion 32 is formed at a position corresponding to (12) so that the rotation amount of the fan blades 30 is adjusted so that the rotational angle of the conventional driving centrifugal fan is the same amount in the forward and reverse rotation of the conventional drive centrifugal fan. Since several fan blades are formed perpendicular to the upper surface of the fan body to obtain the flow resistance and the air flow rate, the friction with the air during the rotation of the fan blades is large, which can solve the problem that the fan increases noise and decreases the cooling efficiency. It is an effective invention.
