Patent ID: 7099571

Claim:
A steam-supplying apparatus, comprising: a steam-generating portion generating steam; an electromagnetic valve receiving the steam from the steam-generating portion, the electromagnetic valve having a valve main body and forming a heating steam circulation passage inside the electromagnetic valve to heat the inside of the electromagnetic valve with the steam from the steam-generating portion when the electromagnetic valve is in a closed state; a tube receiving the steam from the electromagnetic valve when the electromagnetic valve is in an open state, the tube being flexible; a return pipe receiving steam from the electromagnetic valve when the electromagnetic valve is in both the closed and open state, the return pipe being distinguishable from the tube; a steam-blowing portion receiving the steam from the tube; and an electric heater being disposed in the steam-blowing portion to heat a vaporization space of a steam passage in the steam-blowing portion, the electric heater changing water drops to steam in the vaporization space, the steam-blowing portion outputting steam and not water drops, wherein, when the electromagnetic valve is in the closed state, steam circulates from the steam-generating portion through the heating steam circulation passage and around the valve main body and to the return pipe.
