본 고안은 차량, 선박 또는 발전기에 탑재되는 엔진에 있어 배기가스를 배출시키는 배기소음기에 관한 것으로, 보다 상세하게는 엔진에 상향식으로 설치되는 배기소음기를 통해 빗물이 흘러들어 왔을 경우에 이를 처리할 수 있게 하고, 배기 배압(back pressure)을 최소화시킬 수 있도록 하는 엔진용 배기소음기의 구조에 관한 것이다.The present invention relates to an exhaust silencer for exhausting exhaust gas in an engine mounted on a vehicle, a ship, or a generator, and more particularly, when rainwater flows through an exhaust silencer installed upwardly in an engine. And an exhaust silencer for an engine that enables to minimize exhaust back pressure.

제1도 및 제2도는 종래의 배기소음기를 도시한 것이다. 도시된 바와 같이 종래의 배기소음기(50)는 다수의 구멍이 형성된 소음기(52))와, 그 외부를 감싸고 있는 커버(54)로 구성되며, 소음기(52))의 외부와 커버(54)의 내부 사이에는 일정간격을 두고 구멍(56a)을 구비한 배플플레이트(56)가 형성된 구조를 가지고 있다. 도면중 미설명부호 58은 엔진의 배기파이프와 연결되는 배기가스 입구측 플랜지이고, 부호 60은 배기가스 배출측의 플랜지를 도시한 것이다.1 and 2 show a conventional exhaust silencer. As shown, the conventional exhaust silencer 50 is composed of a silencer 52 having a plurality of holes formed therein, and a cover 54 surrounding the outside thereof, and the outside of the silencer 52 and the cover 54. It has a structure in which the baffle plate 56 which has the hole 56a at predetermined intervals between them is formed. In the figure, reference numeral 58 denotes an exhaust gas inlet side flange connected to the exhaust pipe of the engine, and reference numeral 60 shows a flange on the exhaust gas discharge side.

상기와 같은 종래의 배기소음기(50)를 엔진에 상향식으로 설치하였을 때 비가 내리게 되면 배기가스 배출측의 플랜지(60) 부위를 별도 덮개 등을 이용하여 막아 주어야 빗물이 배기소음기(50)의 내부로 유입되는 것을 차단할 수 있는데 반하여, 바람을 동반한 비일 경우에는 덮개가 열려지면서 빗물이 배기소음기(50)의 내부로 흘러들어와 그 빗물이 유입량에 따라 엔진에 치명적인 손상을 발생시킬 수 있는 문제점을 지니고 있다.When rain comes down when the conventional exhaust silencer 50 is installed upward in the engine, rain water must be prevented by using a separate cover or the like to cover the flange 60 on the exhaust side of the exhaust silencer 50. On the other hand, in case of rain accompanied by wind, rainwater flows into the exhaust silencer 50 while the cover is opened, and the rainwater has a problem of causing fatal damage to the engine according to the inflow amount. .

한편 배기소음기(50)의 내부에 형성된 배플플레이트(56)는 일정간격을 두고 설치되어 있기 때문에 배압이 많이 걸리게 되어 출력손실도 많고, 제작 및 공수가 그 만큼 많아 제작의 곤란성이 있을 뿐만 아니라 배플플레이트(56)의 전둘레 용접이 거의 불가능하여 완전히 실링이 곤란하기 때문에 빗물이 흘러들어 올 수밖에 없는 구조를 가지게 되는 구조적인 문제점을 지니고 있는 것이다.On the other hand, the baffle plate 56 formed inside the exhaust silencer 50 is installed at a predetermined interval, so that the back pressure is increased, and thus the output loss is large, and the production and the number of the maneuvers are many, making the baffle plate difficult as well. Since the whole circumference welding of (56) is almost impossible to seal completely, it has a structural problem of having a structure in which rain water can only flow in.

따라서 본 고안은 상기와 같은 종래 기술의 문제점을 해결하기 위해 창안 된 것으로, 배기소음기의 내부로 빗물이 흘러들어 왔을 경우에 이 빗물이 그 내부에서 처리할 수 있게 하고, 배기소음기에 배압이 걸리지 않도록 하여 소음기의 성능에 크게 만족시킬 수 있도록 하는 엔진용 배기소음기의 구조를 제공하는 데 그 목적이 있다.Therefore, the present invention was devised to solve the problems of the prior art as described above, and when rainwater flows into the exhaust silencer, the rainwater can be treated therein, and the backpressure is not applied to the exhaust silencer. The purpose of the present invention is to provide an engine exhaust silencer that can greatly satisfy the performance of the silencer.

상기의 목적을 실현하기 위한 본 고안은 소음기와 커버 사이에 흡음재를 충전시켜 유입된 빗물이 흡수되게 하고, 소음기의 하부에 형성된 배기포트의 상단에 빗물유입안내편을 형성하여, 이 빗물유도안내편을 따라 배기포트의 외부둘레와 커버의 내부둘레에 다공원판을 보유한 빗물탱크를 형성하여 빗물 탱크에 빗물이 고이도록 하여서 고인 빗물을 배수용 콕을 통해 밖으로 배출시킬 수 있게 한 것이 특징이다.The present invention for realizing the above object is to fill the sound absorbing material between the silencer and the cover so that the rainwater is absorbed, and the rainwater inflow guide piece is formed on the upper end of the exhaust port formed in the lower portion of the silencer, A rainwater tank having a multi-parking plate is formed along the outer circumference of the exhaust port and the inner circumference of the cover so that the rainwater collects in the rainwater tank so that the deceased rainwater can be discharged out through the drain cock.

여기서 빗물탱크에 빗물이 고인 정도를 확인하기 위해 빗물탱크에 수위체크용 게이지를 설치하는 것이 바람직하다.It is preferable to install a water level check gauge in the rainwater tank to check the degree of rainwater accumulated in the rainwater tank.

이항, 본 고안의 일실시예를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.If described in detail by the accompanying drawings, an embodiment of the present invention as follows.

제3도는 본 고안의 배기소음기의 정단면도이고, 제4도는 제3도의 B-B 선단면도를 도시한 것이다.FIG. 3 is a sectional front view of the exhaust silencer of the present invention, and FIG. 4 is a sectional view taken along line B-B of FIG.

도시된 바와 같이 본 고안의 배기소음기(10)는 소음기(12)와 커버(14) 사이에 흡음재(16)를 충전시킨다. 상기 흡음재(16)는 배기가스의 온도 약 600℃에서 충분히 견딜 수 있는 것이어야 하고, 빗물의 흡수가 잘 되어야 한다.As shown, the exhaust silencer 10 of the present invention fills the sound absorbing material 16 between the silencer 12 and the cover 14. The sound absorbing material 16 should be able to withstand sufficiently at the temperature of the exhaust gas of about 600 ℃, it should be well absorbed rain water.

소음기(12)의 하부에 형성되는 배기포트(18)의 상부둘레에 안쪽으로 경사진 빗물유입안내편(18a)을 형성하고, 이 빗물유입안내편(18a)을 따라 배기포트(18)의 외부둘레와 커버(14)의 내부둘레 사이에 다수의 빗물유입구멍(20a)이 형성된 다공원판(20)을 보유한 빗물탱크(22)가 설치되며, 빗물탱크(22)의 하부에는 배수용 콕(24)이 형성되어 구성된 것이며, 상기 빗물탱크(22)의 중앙에는 빗물의 유입량을 체크하기 위한 수위체크용 게이지(도시생략)를 포함하여 구성한 것이다.A rainwater inflow guide piece 18a inclined inward is formed in an upper circumference of the exhaust port 18 formed in the lower portion of the muffler 12, and the outside of the exhaust port 18 along the rainwater inflow guide piece 18a. A rainwater tank 22 having a multi-parking plate 20 having a plurality of rainwater inflow holes 20a formed between the circumference and the inner circumference of the cover 14 is installed, and a drain cock 24 is disposed below the rainwater tank 22. ) Is formed and is configured to include a water level check gauge (not shown) for checking the inflow of rainwater in the center of the rainwater tank 22.

상기와 같이 구성된 본 고안에 의하면 빗물이 소음기(12)의 내부로 흘러들어오게 되면 빗물은 소음기(12)의 벽을 타고 흘러내리면서 1차적으로 흡음재(16)가 이를 흡수하게 된다. 이때 적은 량의 빗물이 들어왔을 경우에는 흡음재(16)가 거의 흡수를 하게 되고 또한 배기가스의 열에 의해 밖으로 배출되게 되어 빗물은 소음기(12)의 하부까지 도달되지 않게 된다. 한편 소음기(12)의 내부로 빗물의 유입이 많을 경우에는 1차적으로 흡음재(16)가 흡수하고, 그 나머지는 소음기(12)의 내벽을 타고 내려오다가 2차적으로 빗물유도안내편(18a)을 따라 빗물유입구멍(20a)이 형성된 다공원판(20)을 거쳐 빗물탱크(22)로 고이게 된다. 따라서 소음기(12)를 통해 흘러들어온 빗물은 흡음재(16)와 빗물탱크(22)에 흡수되거나 고이게 되어 빗물유입에 따른 엔진의 손상을 사전에 예방할 수 있는 효과를 가지게 되며, 또한 종래와 같은 배플플레이트가 삭제되고, 그 대신에 흡음재를 설치함으로써 배압이 최소로 걸려 엔진의 출력 저하를 막아 주고, 조립 및 설치가 용이한 이점을 가지게 된다.According to the present invention configured as described above when rainwater flows into the interior of the silencer 12, the rainwater flows down the wall of the silencer 12, and the sound absorbing material 16 absorbs it. At this time, when a small amount of rainwater enters the sound absorbing material 16 is almost absorbed and is discharged out by the heat of the exhaust gas so that rainwater does not reach the lower portion of the muffler 12. On the other hand, when there is a large amount of rainwater into the silencer 12, the sound absorbing material 16 is primarily absorbed, and the rest is descended on the inner wall of the silencer 12, and the rainwater induction guide piece 18a is secondary. The rainwater inlet 20a is formed through the multi-park plate 20 is formed in the rainwater tank 22. Therefore, the rainwater flowing through the silencer 12 is absorbed or accumulated in the sound absorbing material 16 and the rainwater tank 22 to have an effect of preventing damage to the engine due to the inflow of rainwater in advance, and also the baffle plate as in the prior art. By removing the sound absorbing material, the back pressure is minimized, thereby preventing the engine from lowering the output, and the assembly and installation are easy.

상기에서 빗물탱크(22)에 빗물의 고인 정도를 수위측정용 게이지로 확인한 다음 배수용 콕(24)을 열어 빗물을 밖으로 배출시키면 되는 것이다.The rainwater tank 22 is to check the degree of rainwater is accumulated in the gauge for measuring the water level and then open the drain cock 24 to discharge the rainwater out.

이상에서와같이 본 고안의 엔진용 배기소음기의 구조에 의하면 빗물이 소음기 내부로 들어온다 하더라도 흡음재가 빗물을 흡수하고, 또 빗물탱크가 이를 처리하게 되어 유입된 빗물로 인한 엔진의 손상을 방지할 수 있는 이점과, 배기 배압을 최소화시켜 엔진의 출력증대를 도모하는 이점을 가지게 되는 것이다.As described above, according to the structure of the engine exhaust silencer of the present invention, even if the rainwater enters the silencer, the sound absorbing material absorbs the rainwater, and the rainwater tank handles it, thereby preventing damage to the engine due to the inflow of rainwater. This has the advantage of minimizing the exhaust back pressure and increasing the output of the engine.
