  • Patent number: 6438876
    Abstract: An electric steam iron includes an electrically heated soleplate (2). The soleplate (2) has at least one steam vent (20). The iron also includes a controllable steam generator (6) for supplying steam to the steam vent (20). The iron further includes a controller (16) for controlling the steam generator (6) and a temperature sensor (24) for sensing the tempature of the soleplate (2). The temperature sensor (24) supplies a temperature dependent signal to the controller (16). The controller (16) is adapted to activate the steam generator (6) in accordance with a predetermined steam pattern. The steam pattern includes at least a first phase of a first predetermined duration, in which steam is supplied a substantially constant peak steam rate, and at least a second phase, in which team is supplied at a substantially constant lower steam rate. At least the peak steam rate depends upon the temperature of the soleplate (2).
