ABSTRACT:
An electric steam iron has a sole plate, a housing carried on the sole plate and defining a substantially closed chamber adapted to hold a body of water, at least one electric heater for heating the water in the chamber to above 100.degree. C., and a valve at the chamber for maintaining the chamber under superatmospheric pressure. Thus superheated steam is produced therein by the heater. A conduit extending between the chamber and the sole plate conducts this superheated steam to the sole plate. The water chamber is above the sole plate and the housing forms another chamber constituting part of the conduit and in turn above the water chamber. The valve is between the chambers and only permits fluid flow into the upper chamber from the water chamber when the pressure in the water chamber is above a predetermined superatmospheric level. The rest of the conduit is formed by a tube that extends vertically through both chambers and has an upper end opening into the upper chamber and a lower end opening downward through the sole plate. The housing has a thin partition wall subdividing the chambers from each other and carrying the valve.
