An electric steam iron housing has a sole plate with a generally flat upper surface having affixed thereto a one-piece heating assembly having a front portion and a rear portion. The front portion contains a serpentine steam generating passage with an inlet communicating with a water supply container on the housing and steam outlet leading to steam vent openings extending through the sole plate. The rear portion includes top and sidewalls defining a downwardly open chamber in which is disposed a multilayer PTC electric heating element assembly in surface-to-surface contact with the upper surface of the sole plate for heating the sole plate and the steam generating passage. An adjustable thermostat responsive to the temperature of the sole plate is connected in series with the heating element. The handle of the iron is detachable and designed to serve as a storage case for the iron and the iron can be placed in the case only when the thermostat adjustment knob is in the “Off”position.

A portable steam iron, comprising: a hollow housing; a sole plate at the base of the housing; a steam vent in the sole plate communicating with said hollow housing for outlet of steam from the housing; a water inlet to the housing and a water supply on said housing in communication with the inlet to the hollow of the housing for delivery of water to the housing; a generally serpentine passage defined in and through the hollow of the housing and placed and shaped for transmitting water from the vicinity of the inlet toward the steam vent and for transmitting steam to the steam vent; heat generating means in the hollow of the housing for heating water in the passage for generating steam in the passage from water in the passage, said passage having elements therein for defining a heating surface for water, and also for heating the sole plate to an ironing temperature, the heat generating means being provided with means for establishing different levels of heating of the sole plate; the iron also comprising temperature control means having a selector knob in the housing and operatively connected to the heat generating means for selecting a heat setting for the heating means; and a handle detachably attachable to the housing for supporting the housing in use; the handle also having means defining a storage case for the iron emplaceable with respect to the periphery of the housing and with respect to the periphery of the sole plate; the selector knob being shaped and positioned with respect to the periphery of said housing and the sole plate to interfere with the emplacement and removal of the handle into the storage position; the knob having a cut away portion which provides clearance for allowing the handle to be moved past the knob to the storage position; the cut away portion being located on the knob so that when the knob is rotated to the position for the heating means to be off, the cut away portion is positioned relative to the periphery of the housing and the sole plate to permit the handle to be moved past the knob through the cut away portion to the storage position.
