본 고안은 환기에 사용되는 고정식 흡출기에 관한 것이다. 일반적으로 동력을 이용하지 않는 흡출기는 바람에 의해 환기되도록 한 구조를 갖는다.The present invention relates to a stationary aspirator used for ventilation. In general, a power-free aspirator has a structure that allows it to be ventilated by wind.
일 예를들면 바람을 타고 회전하는 회전익에 의해 환기소통이 원활하게 이루어지도록 한 회전식흡출기 또는 바람부는 방향으로 지향하여 풍량을 최대한 받아들이도록 하여 환기소통이 행해지는 풍향지향식을 들수 있으나 이들은 구조가 복잡하여 제조단가가 비싸고 설치장소 주변의 환경에 따라 제약을 받게 되는 문제가 있다. 한편, 가장 보편적으로 사용되는 것으로는 다수의 닥트판을 입설하고 그 상부에 덮개를 씌운 고정식 흡출기가 있다. 이 고정식흡출기는 설치가 간편하고 제조단가 또한 저렴하다는 장점은 있지만 환기성능이 전술한 회전식이나 풍향지향식보다 열등하다는 결점이 있다. 본 고안은 상기한 결점을 해결하고자 종래 공지된 고정식 흡출기의 환기성능을 향상시키려 함에 그 목적이 있는 것으로 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.For example, a rotary aspirator which allows ventilation to be smoothly carried out by a rotorcraft rotating through the wind, or a wind-directed manner in which ventilation is communicated by directing the wind portion to receive the maximum amount of airflow. There is a problem that the manufacturing cost is complicated and is restricted depending on the environment around the installation place. On the other hand, the most commonly used is a fixed aspirator in which a plurality of duct plates are inserted and covered thereon. This stationary aspirator has the advantage of easy installation and low manufacturing cost, but has the drawback that the ventilation performance is inferior to that of the rotary or wind-directed system described above. The present invention has the purpose to improve the ventilation performance of a conventionally known fixed aspirator in order to solve the above-described drawback when described in detail according to the accompanying drawings.
제1도의 도시와 같이 하측연접관(1)의 상부주면에 깔대기(2)를 뒤엎은 형상으로 부착하고 깔대기(2)의 상면에 다수의 닥트판(3)을 입설하여 상측에 덮개(4)를 씌워 깔대기(2)의 중앙 통공(5)을 통해 환기통로가 형성되도록 한다.As shown in FIG. 1, the funnel 2 is attached to the upper circumferential surface of the lower connection pipe 1 in an inverted shape, and a plurality of duct plates 3 are placed on the upper surface of the funnel 2 to cover the lid 4. Cover the ventilation passage is formed through the central through hole (5) of the funnel (2).
이와같은 구조에 의하여 제2도의 도시와 같이 닥트판(3)의 내측부(3a)는 외측부(3b)보다 그 단면적이 협소해지게 된다. 따라서 바람이 임의방향(도면에서 화살표 A 방향)으로 불어든다고 가정하면 닥트판(3)의 내, 외측부(3a),(3b) 단면적 차이로 말미암아 내측부(3a)측의 압력이 외측부(3b)측의 압력보다 낮아지게 된다. 즉, 바람이 외측부(3b)를 통과할 때는 속도가 늦고 압력이 커지게 되나. 내측부(3a)에 이르러서는 속도가 빨라지는 반면에 압력은 작아지게 된다. 따라서 환기통(C)의 내부 압력보다 낮아지게 되기 때문에 압력이 높은 환기통(C)내부에서 압력이 낮은 하측연접관(1)의 상방중앙통공(5)부위로 상승되는 기류가 발생케 되어 능률적이고 효과적인 환기가 이루어지게 된다. 본 고안의 실시예에서 내측부(3a)의 칫수는 하측연접관(1)의 직경에 1/2정도가 되도록 함이 바람직하다.By such a structure, as shown in FIG. 2, the inner side part 3a of the duct board 3 becomes narrower than the outer side part 3b. Therefore, assuming that the wind blows in an arbitrary direction (in the direction of arrow A in the drawing), the pressure on the inner side 3a side is increased due to the cross-sectional area difference between the inner, outer sides 3a and 3b of the duct plate 3. Will be lower than the pressure. In other words, when the wind passes through the outer portion (3b) is slow and the pressure increases. When the inner portion 3a is reached, the speed is increased while the pressure is reduced. Therefore, since the pressure is lower than the internal pressure of the ventilation cylinder (C), the air flow rising to the upper central through hole (5) of the lower connection pipe (1) with low pressure is generated inside the ventilation cylinder (C) where the pressure is high. And effective ventilation is achieved. In the embodiment of the present invention, the dimension of the inner portion (3a) is preferably to be about 1/2 of the diameter of the lower connection pipe (1).
상술한 바와같이 본 고안은 공지된 고정식흡출기의 외양과 동일하게 하는 반면에 환기통로만을 외측이 넓고 내측이 좁도록 형성해줌으로써 제조비의 상승을 초래함이 없이 환기성능을 대폭 향상시킨 실용적인 고안인 것이다.As described above, the present invention is a practical design that greatly improves the ventilation performance without causing an increase in manufacturing cost by forming the ventilation passage only on the outside and narrowing on the inside, while making the same as the appearance of the known fixed suction system. .
