Description

本発明は、水排出装置に関する。   The present invention relates to a water discharge device.

内燃機関の排気ガス中に含まれる水蒸気が冷えて液化し、この水が排気系の消音器内に溜まることがある。このように、水が溜まると、この溜まった水により、消音器の腐食が促進される恐れがある。   The water vapor contained in the exhaust gas of the internal combustion engine may be cooled and liquefied, and this water may accumulate in the silencer of the exhaust system. Thus, when water accumulates, corrosion of a silencer may be accelerated | stimulated by this accumulated water.

そのため、従来、消音器内に溜まった水を除去するために、図８に示すように、アウトレットパイプ１０１内と消音器のケース１０２内とを連通する連通管１０３を設け、排気流によりこの連通管１０３を通じてアウトレットパイプ１０１内に水を吸い上げて、排気ガスと共に外部へ排出するものがある。   Therefore, conventionally, in order to remove the water accumulated in the silencer, as shown in FIG. 8, a communication pipe 103 is provided to connect the outlet pipe 101 and the case 102 of the silencer. There is one that sucks water into the outlet pipe 101 through the pipe 103 and discharges it to the outside together with the exhaust gas.

この図８に示す連通管１０３は、アウトレットパイプ１０１の軸芯に至るほど下流側に傾斜するように設け、その連通管１０３のアウトレットパイプ１０１内に突出させた開口部１０４を、アウトレットパイプ１０１の軸芯に対して直交するように切断して設けたものが知られている（特許文献１参照）。   The communication pipe 103 shown in FIG. 8 is provided so as to be inclined toward the downstream side as it reaches the axial center of the outlet pipe 101, and an opening 104 projecting into the outlet pipe 101 of the communication pipe 103 is provided in the outlet pipe 101. What was cut and provided so that it might orthogonally cross with respect to an axial center is known (refer patent document 1).

しかし、上記従来の連通管１０３においては、アウトレットパイプ１０１の軸芯に至るほど下流側に傾斜するように設けるとともに、その開口部１０４を、アウトレットパイプの軸芯に対して直交するように設けるため、この連通管１０３のアウトレットパイプ１０１内への出代Ｈ１が大きくなり、この連通管１０３により、アウトレットパイプ１０１内を流れる排気ガス流が乱されて、気流騒音が発生するという問題がある。   However, the conventional communication pipe 103 is provided so as to incline toward the downstream side as far as the axial center of the outlet pipe 101 and the opening 104 is provided so as to be orthogonal to the axial center of the outlet pipe. The outlet H1 of the communication pipe 103 into the outlet pipe 101 becomes large, and the exhaust pipe flow through the outlet pipe 101 is disturbed by the communication pipe 103, and airflow noise is generated.

そこで、本発明は、上記問題点を解決した水排出装置を提案することを目的とする。   Then, an object of this invention is to propose the water discharge apparatus which solved the said problem.

前記の課題を解決するために、本発明は、気体が流通する流路内に開口する連通管を設け、該連通管により流路の外部に溜まった水を排出する水排出装置であって、
前記連通管の流路内の開口部を、流路の下流側に向かって開口するとともに、その開口部の下流側端を、その開口部の上流側端よりも、下流側で、かつ、流路の軸芯から離間する位置に形成したことを特徴とするものである。 In order to solve the above-mentioned problems, the present invention is a water discharge device that provides a communication pipe that opens in a flow path through which gas flows, and discharges water accumulated outside the flow path by the communication pipe,
The opening in the flow path of the communication pipe is opened toward the downstream side of the flow path, and the downstream end of the opening is on the downstream side of the upstream end of the opening, and the flow It is characterized in that it is formed at a position away from the axis of the road.

また、前記流路内を流れる気体により、前記流路内を流れる気体により、前記連通管内の前記開口部付近が負圧となるように、前記開口部の下流側端を、その開口部の上流側端よりも、下流側で、かつ、流路の軸芯から離間する位置に形成してもよい。   Further, the gas flowing in the flow channel causes the downstream end of the opening to be upstream of the opening so that the gas flowing in the flow channel has a negative pressure in the vicinity of the opening in the communication pipe. You may form in the position downstream from the side end and spaced apart from the axial center of a flow path.

本発明によれば、連通管における流路内の開口部を、下流側に向かって開口するとともに、その下流側端は、その開口部の上流側端よりも下流側で、かつ、流路の軸芯から離間する位置に形成したことにより、上記従来技術と比較して、連通管の流路内への突出量を少なくすることができ、気流騒音の発生を抑制することができる。   According to the present invention, the opening in the flow channel in the communication pipe is opened toward the downstream side, and the downstream end is downstream of the upstream end of the opening, and the flow channel By forming at a position away from the shaft core, the amount of protrusion of the communication pipe into the flow path can be reduced as compared with the conventional technique, and the generation of airflow noise can be suppressed.

A plurality of through holes 14 are formed in the peripheral wall of the inlet pipe 10.

アウトレットパイプ１１には、ケース２の略中央部に位置して設けられており、アウトレットパイプ１１の車両搭載時における底部には、断面円形の円筒状の連通管１５が、アウトレットパイプ１１内の流路に開口して設けられている。連通管１５は、図３に示すように、上流側Ｃから下流側Ｄに向かうほど、アウトレットパイプ１１の軸芯Ｘ−Ｘに近づくように傾斜して、アウトレットパイプ１１内に挿通されている。   The outlet pipe 11 is provided at a substantially central portion of the case 2. A cylindrical communication pipe 15 having a circular cross section is provided at the bottom of the outlet pipe 11 when the vehicle is mounted on the vehicle. Open to the road. As illustrated in FIG. 3, the communication pipe 15 is inserted into the outlet pipe 11 so as to be closer to the axial center XX of the outlet pipe 11 as it goes from the upstream side C to the downstream side D.

The protrusion amount H2 into the communication pipe 15 in the pipe 11 can be reduced, the disturbance of the exhaust gas passing through the outlet pipe 11 can be reduced, and the generation of airflow noise can be suppressed.

また、アウトレットパイプ１１内を流れる排気ガスにより、連通管１５内の開口部１６付近が負圧となるように、連通管１５の開口部１６を、アウトレットパイプ１１の軸芯に対して傾斜させることで、ケース２内に溜まった水を、効率よくアウトレットパイプ１１内に吸い出して排出することができる。   Further, the opening 16 of the communication pipe 15 is inclined with respect to the axis of the outlet pipe 11 so that the exhaust gas flowing in the outlet pipe 11 has a negative pressure near the opening 16 in the communication pipe 15. Thus, the water accumulated in the case 2 can be efficiently sucked into the outlet pipe 11 and discharged.
