본 발명은 제연송풍팬에 관한 것으로, 좀 더 상세하게는 공동주택이나 고층건물에 화재가 발생하였을 경우 비상공간에 바람을 불어넣어 질식을 막아 인명을 보호하는 제연송풍장치의 송풍팬에 관한 것이다,The present invention relates to a ventilation fan, and more particularly, to a blower fan of the ventilation device to protect people by blowing air into the emergency space in the event of a fire in the apartment house or high-rise building to prevent asphyxiation.

일반적으로, 제연송풍장치는 흡입구와 배출구가 구비된 덕트의 내부에 송풍팬이 구비되고, 상기 송풍팬의 일측에는 구동모터가 구비되며, 상기 송풍덕트의 배출구에는 각 층으로 연결되는 분기관이 구비되는 배관이 구비된다.In general, the ventilation fan is provided with a blowing fan inside the duct provided with the inlet and outlet, a driving motor is provided on one side of the blowing fan, the outlet of the blowing duct is provided with branch pipes connected to each layer. The piping is provided.

여기에서 상기 송풍팬의 종류는 후곡형(後曲形), 익형(瀷形), 다익형(多翼形) 등이 있다.The type of the blowing fan may be a curved shape, airfoil, multi-foil shape, or the like.

상기 후곡형(後曲形)은 블레이드(blade)의 끝부분이 회전방향의 뒤쪽으로 굽은 날개곡선을 갖는 것으로 풍압은 좋으나 풍량이 적어 터보형송풍기에 적용된다.The rear curved shape has a blade curve bent toward the rear of the rotational direction, and the wind pressure is good, but the air volume is small and is applied to a turbo blower.

상기 다익형(多翼形)은 블레이드의 끝부분이 회전방향으로 굽은 전곡형으로 풍량은 좋으나, 풍압이 낮아서 일반 공조용에 적용된다.The multi-blade is a full-curved bent end of the blade in the rotational direction, the air volume is good, but the air pressure is low, it is applied for general air conditioning.

상기와 같은 송풍팬을 이용한 제연송풍장치는 화재시 방화문이 정상적으로 차폐되지 않을 경우 비상공간 내부의 공기가 외부로 누출되면서 송풍기의 풍량 증가로 송풍기에 과부하가 발생하고, 결국 구동모터의 작동이 정지되어 건물 내에서의 인명 피해가 우려되는 문제점이 있었다.When the fire door is not normally shielded in case of fire, the ventilation fan using the blower fan is leaked to the outside of the emergency space, causing an overload to the blower due to the increase of the air volume of the blower, and eventually the operation of the driving motor is stopped. There was a problem that the damage to life in the building is concerned.
