Abstract

A muffler with ease discharge of condensate may include a housing formed of a cylinder shape and provided with an end plate at both end portions thereof, at least one baffle disposed in the housing to divide the internal space of housing into a plurality of chambers, an inlet pipe introducing exhaust gas in the housing, an outlet pipe discharging the exhaust gas from the housing the outside, so that the exhaust gas flowed into the inlet pipe flows through the chamber divided in the housing to be discharged through the outlet pipe, a condensate collecting tube disposed along the lower surface of the housing and provided with a passage in which the condensate gathered in the lower surface of the housing is introduced to be flowed and a condensate inducing tube connecting the condensate collecting tube and the outlet pipe.

First claim

What is claimed is:

1. A muffler for ease discharge of condensate, the muffler including:
a housing formed of a cylinder shape and provided with end plates at first and second end portions of the housing and at least one baffle mounted in the housing to divide an internal space of the housing into a plurality of chambers;
an inlet pipe connected to the housing and introducing exhaust gas in the housing;
an outlet pipe connected to the housing and discharging the exhaust gas from the housing to an outside of the housing, wherein the exhaust gas flowed into the inlet pipe flows through the plurality of chambers divided in the housing to be discharged through the outlet pipe in a state of noise being controlled;
a condensate collecting tube mounted along a lower surface of the housing and provided with a passage in which the condensate gathered in the lower surface of the housing is introduced to be flowed therein; and
a condensate inducing tube connecting the condensate collecting tube and the outlet pipe,
wherein the condensate collecting tube includes:
a condensate suction hole into which the condensate is flowed from the lower surface of the housing to the condensate collecting tube; and
a condensate collection line formed inside the condensate collecting tube along the condensate collecting tube, wherein the condensate flowed through the condensate suction hole is guided toward the condensate collecting tube,

wherein the condensate suction hole is formed on a lower surface of the condensate collecting tube, and
wherein the condensate suction hole is formed in a plurality at intervals along a longitudinal direction of the condensate collecting tube.

2. The muffler for ease discharge of the condensate of claim 1 ,
wherein the condensate inducing tube is mounted on one of the end plates.

3. The muffler for ease discharge of the condensate of claim 1 ,
wherein the condensate collection line is formed inside the condensate collecting tube along the longitudinal direction of the condensate collecting tube.

4. The muffler for ease discharge of the condensate of claim 3 ,
wherein the condensate suction hole is in plural to form a plurality of condensate suction holes, and
wherein the condensate collection line is fluidically-communicated with all the plurality of condensate suction holes.

5. The muffler for ease discharge of the condensate of claim 1 ,
wherein the housing is formed in a round shape so that the lower surface of the housing is a lowest portion at a middle portion of the housing along forward and backward direction of a vehicle; and
wherein the condensate collecting tube is mounted along a length direction of the vehicle.

6. The muffler for ease discharge of the condensate of claim 5 ,
wherein the condensate collecting tube is mounted at a portion where the housing and one of the end plates are contact with each other.

7. The muffler for ease discharge of the condensate of claim 6 ,
wherein the condensate collecting tube is mounted to be contacted with the one of the end plates provided at a portion where the outlet pipe is connected to a tail pipe through which the exhaust gas is discharged.

8. The muffler for ease discharge of the condensate of claim 1 ,
wherein the housing is sloped so that a portion where the condensate collecting tube is mounted is positioned at a lowest portion of the housing.

9. The muffler for ease discharge of the condensate of claim 8 ,
wherein each baffle includes a penetration hole formed at a side of a circumference of each baffle so that the condensate passes through the baffle and moves to another adjacent chamber among the plurality of chambers through the penetration hole.

10. The muffler for ease discharge of the condensate of claim 9 ,
wherein the penetration hole is formed at a lowest potion of the circumference of the baffle contacting the housing.

11. The muffler for ease discharge of the condensate of claim 10 ,
wherein the housing is formed to be sloped so that the lowest portion of the housing is a side of one of the end plates provided at a portion where the outlet pipe and a tail pipe through the exhaust gas is discharged are connected to each other.
