Claim:
A condensed water discharge apparatus of a muffler, comprising: a through hole formed at a bottom of a muffler case; an inflow pipe fluidly communicating with an interior of the muffler case through which exhaust gas flows; an exhaust pipe fluidly communicating with atmosphere so that exhaust gas is exhausted from the muffler case therethrough; a thermoelement mounted adjacent the inflow pipe to generate an electric power with a temperature of exhaust gas; and a control valve that is mounted at the through hole and is electrically connected with the thermoelement so as to selectively open and close the through hole by the electric power of the thermoelement when a vehicle is driven or stopped; wherein the control valve includes: a valve body having a cylindrical shape; upper and lower flanges respectively formed at an upper end and a lower end of the valve body so as to be symmetrical about the bottom of the case, the upper flange disposed inside the muffler case and the lower flange being disposed outside the muffler case; and an electromagnet interposed between the upper flange and the lower flange and, electrically connected with the thermoelement, wherein the electromagnet selectively opens the through hole by the electric power received from the thermoelement.
