Iron vaporization chamber coating

#The present invention concerns steam irons.

#These irons conventionally have a soleplate composed of a body generally made of cast aluminum, and a cap covering the lower part of the body and coming into contact with the items to be ironed. The body of the soleplate generally of aluminum comprises a heating element, a chamber for quasi-instantaneous vaporization of water and channels for distribution of the steam produced toward steam orifices directed onto the items through the cap.

#The body of the soleplate must assure vaporization of the water as well as temperature maintenance of the cap.

#The invention will be better understood from a reading of the example below and from the attached drawing.

#FIG. 1 is a view in longitudinal cross section in a vertical plane of a steam iron soleplate having a coated vaporization chamber, the soleplate being horizontal. Only the initial cladding of the chamber is represented.

#In a preferred version of the invention, a steam iron has a soleplate composed of a cap 1 constituting the ironing surface, a heating body 2 of aluminum and in thermal connection with this cap. The heating body comprises a heating element 6 and a chamber 3 for the vaporization of water coming from a droplet source positioned on an opening 4 of the closing plate 5 of the steam chamber.

#The cladding of vaporization chamber 3 is composed of an initial cladding on which, according to the invention, is applied a treatment product increasing the vaporization performance of the chamber.

#The initial cladding of vaporization chamber 3 has a layer 10 of sodium silicate adhering strongly to the wall of heating body 2 of aluminum. On this layer is deposited a fabric 11 of glass fibers from which the oiling has been removed after fabrication. A grid 12 maintained by rivets 13 emanating from heating body 2 fixes the fabric of fibers 11. Fabric 11 covers at least the part of chamber 2 that receives the drops of water, in line with opening 4 of closing plate 5.
