A steam injection-type drum washing machine is provided to reduce the washing time and improve the washing force by injecting the steam in the washing tub. A steam injection-type drum washing machine(100) is composed of: dry ducts(110) connected as a shape surrounding the outer peripheral surface of a water storage tub(102) to circulate the air in the water storage tub; a dry pipe(120) placed between the dry ducts to condense the wet air circulated in the dry duct; a blowing fan(130) placed in the dry duct to blow the wet air of the water storage tub to the dry pipe; a spray hose(140) whose one end is combined at the side wall of the dry pipe for spraying and other end is combined with a water supply source; and a heater(150) for changing the moisture sprayed by the spray hose and the wet air in the dry pipe into a hot and wet steam.
