  • Patent number: 4835363
    Abstract: An electric iron wherein a cermic sole plate transmits infrared light and is heated by one or more halogen lamps within a reflector in the housing of the iron whose concave surface faces the lamp or lamps and reflects heat upon the sole plate. The reflector further effects the heating of water which is admitted into a steam chamber in the housing of the iron between the reflector and the ceramic sole plate, and the resulting steam is conveyed to nozzles extending into openings in the sole plate.

  • Patent number: 4774395
    Abstract: An electric heat storage apparatus, such as a steam iron, hot plate, pan, etc., includes a metal body defining a hollow housing enclosing a heat storage device containing a thermally decomposable heat storage substance comprising 30-99% by weight pentaerythritol. The heat storage substance is completely confined in a fluororesin enclosure which isolates the substance from the metal body and prevents contact of ambient air therewith so that the thermal stability of the pentaerythritol is enchanced. The metal body is heated by an electric heating element to a selected temperature for storing heat in the heat storage substance. In the case of use as a cordless electric steam iron, the metal body forms the sole plate of the iron and is provided with a vaporization chamber in heat exchange relationship with the heat storage substance for the generation of steam.

  • Patent number: 4634836
    Abstract: An electric travel iron includes as an upper component a hand-held hot-air type hair dryer having a hand grip, an electric heating unit for heating a stream of air and an outlet duct through which a hot air stream is discharged. The lower component of the iron is formed by a thin flat metallic ironing plate detachably connected to the duct of the dryer in spaced confronting relationship to the open end thereof. The ironing plate is planar and has a surface facing the open duct end to define a direct hot-air impingement surface region and extends laterally outwardly from the direct hot-air impingement region beyond the contour of the duct end for providing a region heated by hot air laterally deflected in all directions from the hot-air impingement region. The hot air impingement region is provided with holes for direct access of hot air to the material being ironed, with the holes being located in a group having a shape corresponding to the contour of the open duct end.

  • Patent number: 4430553
    Abstract: A cordless flatiron includes a sole plate with an exposed bottom surface forming an ironing surface and a top surface including a number of projections extending upwardly therefrom. A protective hood attached to the periphery of the top surface of the sole plate forms an evacuated, sealed chamber thereabove and a heat storage element is positioned in the chamber so as to be movable toward and away from the projections of the sole plate. The heat storage element is heated by an electric heating rod extending therein. A temperature responsive regulator element positioned between the heat storage element and the top of the sole plate and responsive to the temperature of the sole plate is arranged by its configuration to position the heat storage with respect to the upper ends of the projections of the sole plate and thus determine whether or not heat is conducted from the heat storage element to the projections of the sole plate and to the ironing surface of the sole plate.
