상술한 자연적인 실내 환기 구조원리를 해결하기 위한 본 발명의 목적은 조립이 간단하고, 자동차나 기차의 주행시 공기 저항이 작은 벤츄리관닥트 외부형상과 자동차의 여닫이 창문을 동작하지 않아도 자동차 주행에 의하여 실내의 탁한 공기가 자연적으로 배출 되도록 한 벤츄리관닥트구조를 제공하는데있다.An object of the present invention for solving the above-described natural indoor ventilation structure principle is easy to assemble, indoors by driving the car even without operating the venturi tube duct outside shape and the casement window of the car with low air resistance when driving the car or train It is to provide a venturi tube duct structure that allows natural air to be discharged naturally.

자동차가 진행하는 차량 지붕외면에 부착된 벤츄리관닥트는 도1에서와 같이 좌우 2개의 벤추리관 유입구(3)를 가진 닥트로 이곳 단면이 작은 중앙지점 유입관(3)에서 빠른속도로 공기가 통과하면서 공기흐름의 유적선은 지점(a)와 지점(b)에서 큰 압력차가 발생하여 자동차 실내의 탁한 공기를 자연적으로 자동차 주행에 의하여 배출하게 함으로써 쾌적한 실내환경을 유지하도록 하였다Venturi tube duct attached to the outside of the vehicle roof on which the vehicle proceeds is a duct having two left and right venturi tube inlets 3 as shown in FIG. 1 and air flows through the central point inlet tube 3 having a small cross section at high speed. In the meantime, the remains of the airflow caused a large pressure difference between the points (a) and (b) to naturally discharge the muddy air of the car interior by driving the car to maintain a comfortable indoor environment.

이상에서와 같은 본 발명에 따른 벤츄리관닥트를 기차나 자동차등의 지붕(roof)에 부착하고, 주행시 벤츄리관속으로 빠르게 지나는 공기 유체의 흐름이 단면의 변화에 압력차를 발생시켜 실내의 탁한 공기를 유도관(3)을 톤해 자연적으로 배출하는 자동차등 실내환기의 벤추리관닥트구조로 항상 맑은 공기를 유지하게 하므로 운전중 머리를 맑게 하고, 졸음 운전을 방지하는 등 깨끗한 실내환경을 유지하는데 효과가 있다.As described above, the venturi tube duct according to the present invention is attached to a roof of a train or an automobile, and when the air flows rapidly through the venturi tube during driving, a pressure difference is generated in the change of the cross-section, thereby causing muddy air in the room. The venturi tube duct structure of indoor ventilation such as automobile which emits ton by induction pipe (3) keeps fresh air at all times, so it is effective in maintaining clean indoor environment by clearing the head while driving and preventing drowsy driving. .
