Abstract: Heating device for an iron (11) provided with an ironing plate (12), comprising at least a plurality of irradiation lamps (16), which are disposed in cooperation with a first portion (12a) of the ironing plate (12), in order to irradiate a luminous radiation toward a fabric (30) in correspondence with the first portion (12a) of the ironing plate (12). The heating device comprises localized heating means (20) of the reflection type disposed in optical communication with the irradiation lamps (16) through a radiation window (19), and oriented so as to direct at least part of the radiations emitted by the irradiation lamps (16) toward a second portion (12b) of the ironing plate (12), different from the first portion (12a).

Abstract: An electric steam iron for pressing fabrics, which iron includes an ironing sole plate, an electrically operated heating element disposed for heating the sole plate by converting an electric current to heat, and a switch unit for automatically reducing flow of electric current to the heating element when the iron is not in use. The sole plate is formed to have a low heat capacity, and the iron is further provided with a stiffening structure via which the sole plate is fixed in position in the iron, the stiffening structure being permeable to steam and being made of a thermally insulating material.
Abstract: A soleplate of a pressing iron comprises a soleplate which is made from reinforced transparent glass material and has a flat and smooth bottom surface and a waved upper surface. The upper waved surface is coated with an infrared heater which provides a quick heat build-up thereof to heat the soleplate while preserves the heat generated thereof to a long extent as the power is interrupted.
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.
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.

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.

The lower component of the iron comprises a thin flat metallic ironing plate detachably connected to the air outlet duct of the dryer in spaced confronting relationship to the open end of the duct. The ironing plate is planar and has an upper side 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 from the direct hot-air impingement region. The lower side of the ironing plate forms the ironing surface.
Abstract: The electronic circuit of a laundry iron comprises at least one heat-generating element such as a triac or a dropping resistor. The heat dissipator comprises a tubular metallic casing which contains the electronic circuit and is housed within the handle of the laundry iron. The internal cross-section of the handle is similar in shape to the external cross-section of the tubular casing and a thermal bond is provided between the casing and the handle.
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.
Abstract: An apparatus for thermal sealing and bonding the ends of foil wrapped cigarette packages includes a conveyor for transporting a stack of packages through a heat sealing station having heat sealing units arranged on opposite sides of the path of travel of the conveyor for simultaneously heat sealing the ends of the packages. Each heat sealing unit includes a plurality of thin superposed spaced heating strips equal in number to the packages in the stack and mounted in a housing for unitary movement into contact with the ends of the stacked packages. The strips have a low thermal inertia and are made of a metal having a high heat conductivity. The housing encloses a plurality of infrared radiators, one for each strip, spaced from the side of the strips opposite the side of adapted to contact the package ends for heating the strips by radiant heat in a contact free manner.
Abstract: A glass or ceramic cooking vessel of the type commonly employed in slow cookers is provided with heating apparatus for heating the vessel in a substantially uniform manner. An electric heating element is supported in a position spaced from the vessel such that direct conduction of heat to the vessel is prevented, heat transfer means being provided to conduct heat from the heating element to the vessel over an extended portion of the vessel's outer surface.
