ABSTRACT:
Steam generated within a vaporization chamber (4) by water droplets (16) as they fall onto a base (1) in which is embedded a heating resistor (17) is directed onto fabrics to be ironed through sole-plate orifices (26). When the base temperature is high, a closure member (32) attached to a bimetallic strip (33) is opened, steam flows through an intercalary space (23) between the base and the sole-plate, then escapes through a peripheral gap (25), thus completing heat transfers from base to sole-plate by convection and conduction. In the case of low temperatures, the closure member is placed in the closed position, air is admitted into the intercalary space (23) and forms a shield between sole-plate and base. The base temperature is than sufficient for generation of steam while the sole-plate is at a relatively low temperature which permits ironing of delicate fabrics.
