DRAIN DEVICE FOR PREVENTING CORROSION OF PARTS BY REMOVING WATER NATURALLY COLLECTED IN A TRUNK AND A MUFFLER OF A VEHICLE DURING WASHING

摘要

PURPOSE: A drain device of a trunk and a muffler for a vehicle is provided to prevent corrosion of the muffler and the trunk, and to drain water from the trunk and the muffler automatically by opening a trunk water discharge hole valve and a muffler water discharge hole valve with negative pressure in passing high pressure and high temperature exhaust gas through the exhaust pipe in starting the engine. CONSTITUTION: A drain device comprises a trunk water discharge hole(14) formed in the lower part of a tire storage space to discharge water from a trunk(10), a connecting pipe(30) connecting the lower end of the trunk water discharge hole to an exhaust pipe, a trunk water discharge hole valve(40) contained in the connecting pipe to open the trunk water discharge hole by receiving negative pressure of exhaust gas and closed in removing negative pressure to elastically support a valve by a spring, a muffler water discharge hole(23) formed in the lower part of a muffler(20) to discharge water from the muffler, a muffler water discharge hole valve(50) opening and closing the muffler water discharge hole by elastically supporting a valve(51) moving up and down by negative pressure with a spring(52), and a connecting hose(70) opening the muffler water discharge hole valve by receiving negative pressure of exhaust gas and connecting the lower part of the muffler water discharge hole valve to the exhaust pipe.
