Abstract: A steam iron with an electrically heated sole plate has a discardable steam-generating chamber preferably composed of sheet-metal foil or thin metal sheet lined with polytetrafluoroethylene and formed with an inlet for receiving water to be evaporated and an outlet for discharging steam flush with the sole plate, the outlet extending through an opening thereof. The steam-generating chamber has a surface substantially in face-to-face contact with a heat-transferring surface of the heating element and is pressed thereagainst with elastic deformation of the steam chamber via suitable means.
