다시 말해, 제1실시예는 상기 덕트의 흐름공간 210의 굴절 부위 211 모서리 212, 213 양측에 내측격벽 251과 외측격벽 252을 각각 형성시켜 흐름공간 210을 메인흐름공 220과 한 쌍의 서브흐름공 230으로 구분시키고, 상기 서브흐름공 230에 회전수단 100을 설치한다.In other words, in the first embodiment, the inner partition 251 and the outer partition 252 are formed on both sides of the refraction portions 211 and corners 212 and 213 of the flow space 210 of the duct, respectively, thereby forming the flow space 210 as the main flow hole 220 and the pair of sub flow holes. It is divided into 230, and the rotation means 100 is installed in the subflow hole 230.

제2실시예는 상기 덕트의 흐름공간 210의 굴절 부위 211의 모서리 중 오목한 모서리 212에 외측격벽 252을 형성시켜 흐름공간 210을 메인흐름공 220과 서브흐름공 230으로 구분시키고, 상기 오목한 모서리 213측에 형성된 서브흐름공 230에 회전수단 100을 설치한다.

The rotating means 100 is installed in the subflow hole 230 formed at the side.

여기서, 격벽은 굴절 부위에서 설치되는 배치 상태에 따라 외측격벽 252과 내측격벽 251으로 구성된다.Here, the partition wall is composed of the outer partition 252 and the inner partition 251 according to the arrangement state installed at the refractive portion.

즉, 굴절부위 중 볼록한 모서리 212 측에는 외측격벽 252이 설치되고, 오목한 모서리 213 측에는 내측격벽 251이 설치된다.That is, the outer partition 252 is provided on the convex edge 212 side of the refractive portion, and the inner partition 251 is provided on the concave edge 213 side.

그리고, 상기 외측격벽 252은 상기 볼록한 모서리 212에 호 형상 갖도록 하여 회전수단을 부분 수용하는 제1격벽 253과, 상기 볼록한 모서리 212에 간격을 두고 굴절 부위와 동일한 곡률을 갖는 제2격벽 254으로 구성한다.The outer partition 252 includes a first partition 253 having an arc shape at the convex edge 212 and partially accommodating rotation means, and a second partition 254 having the same curvature as the refractive portion at intervals at the convex edge 212. .

상기의 외측격벽 252을 통해 굴절부위의 볼록한 모서리 212 측과 동일한 곡률을 갖도록 하여 원활한 공기 흐름을 가능하도록 한다.The outer partition 252 has the same curvature as that of the convex edge 212 of the refractive portion to enable smooth air flow.

또한, 상기 내측격벽 251은 상기 오목한 모서리 213에 호 형상의 갖도록 하여 회전수단을 부분 수용하는 제1격벽 253과, 상기 제1격벽 253의 수평면 및 수직면을 이음하여 굴절 부위와 동일한 곡률을 갖는 제2격벽 254으로 구성하여 오목한 모서리 213 측과 동일한 곡률을 갖도록 하여 원활한 공기 흐름을 가능하도록 한다.In addition, the inner partition 251 is a second partition having the same curvature as the refracting portion by joining the first partition 253 and the horizontal and vertical planes of the first partition 253 so as to have a concave shape in the concave edge 213 and the part receiving the rotation means; The partition wall 254 has the same curvature as that of the concave edge 213 to enable smooth air flow.

상기와 같이 다양한 실시예를 갖는 덕트 환기장치는 상기 회전수단 100의 구동에 의해 서브흐름공 230의 공기 압력을 높여 메인흐름공 220과의 기압차이를 발생시켜 풍속을 향상시키도록 한다.The duct ventilation device having various embodiments as described above increases the air pressure of the sub-flow hole 230 by driving the rotating means 100 to generate a pressure difference with the main flow hole 220 to improve the wind speed.

구체적으로는, 상기 흐름공간 210을 메인흐름공 220과 서브흐름공 230으로 구분하되, 상기 서브흐름공 230은 흐름공간 210의 굴절 부위 211에만 설치되도록 하여 상기 서브흐름공 230 양측 입구와 출구는 흐름공간 210과 상호 연통되게 설치된다.Specifically, the flow space 210 is divided into a main flow hole 220 and a sub flow hole 230, but the sub flow hole 230 is installed only at the refracting portion 211 of the flow space 210 so that both inlet and outlet of the sub flow hole 230 flow. It is installed in communication with the space 210.

그리고, 한 쌍의 서브흐름공 230 또는 한 쌍의 서브흐름공 230 중 어느 한 개소의 서브흐름공 230에 회전수단 100을 선택적으로 설치하여 구동시키면 서브흐름공 230 내부의 공기 압력을 높인다.Further, when the rotary means 100 is selectively installed and driven in one of the pair of subflow holes 230 or the pair of subflow holes 230, the air pressure inside the subflow holes 230 is increased.

이를 통해 메인흐름공 220과 서브흐름공 230의 기압 차이를 발생시켜 풍속을 증가시킨다.This increases the air pressure by generating a pressure difference between the main flow hole 220 and the sub flow hole 230.

즉, 상기 회전수단 100의 구동에 의해 공기의 속도가 서브흐름공 230에서 기압이 높아지면서 상기 서브흐름공 230의 출구측으로 향상된 풍속 및 풍량을 배출한다. That is, the air velocity is increased in the subflow hole 230 by the driving of the rotating means 100 to discharge the improved wind speed and air volume to the outlet side of the subflow hole 230.

이때, 메인흐름공 220은 기압이 상대적으로 낮아져 공기의 힘은 고기압에서 저기압으로 작용하므로 메인흐름공 220의 기류를 끌어당겨 풍량 및 풍속을 증가시키도록 하는 효과가 있다.At this time, the main flow hole 220 has a relatively low air pressure, so the force of the air acts as a low pressure from the high pressure, thereby attracting the air flow of the main flow hole 220 has the effect of increasing the air volume and wind speed.
