A steam washer is provided to rapidly perform washing by improving thermal efficiency and to be manufactured in a small structure. A steam washer includes a case(10), an exhaust tube(20), a combustion tube(30), first to fourth heat exchangers(40,50,60,70), a surge tank(80), a steam gun(90), and a pump(100). The case has a water tank(11), a fuel tank(12), and wheels(13). The exhaust tube includes a water tub(21) connected to the water tank. The combustion tube includes a burner(31) connected to the fuel tank. The first heat exchanger is installed inside the exhaust tube and connected to the water tub. The second heat exchanger includes a circulation duct(51) connected to lower parts of the exhaust tube and the combustion tube. The surge tank is connected to the third heat exchanger to maintain constant pressure. The steam gun is connected to the surge tank to inject steam. The pump is connected to the exhaust tube to circulate water. |
