Definitions

  • the present invention relates to an iron soleplate, in particular a steam sole.
  • the invention also relates to irons, comprising such a sole.
  • the iron soles, dry or steam, are currently made of aluminum alloy molded in particular by pressure injection.
  • These aluminum alloys have a relatively low hardness, so that the surface of the iron soles is easily scratched when ironing textile articles comprising hard objects such as buttons, zippers, staples, etc.
  • the object of the present invention is to remedy all the aforementioned drawbacks.
  • the soleplate of iron in particular steam, is characterized in that at least its surface intended to be applied to the articles to be ironed, is covered by an enamel coating.
  • this enamel coating effectively protects the soleplate against oxidation caused by water vapor and other chemicals.
  • the stains caused by lime caused by the evaporation of water or by the carbonization of organic matter from ironed articles do not offer any grip on the enamel coating, so that the soleplate is easily cleaned .
  • the enamel coating thus not only prolongs the life of the iron, makes it easier to use and clean, but also reduces the cost of this iron.
  • the sole can be made of aluminum alloy, molded for example by pressure injection, vacuum or molded in a shell and containing silicon. This type of aluminum alloy is economical, but relatively soft. The enamel coating, however, gives the surface of the sole a largely sufficient hardness.
  • the aforementioned drawback is eliminated by forming the enamel coating from a sintered enamel frit at a temperature below 500 ° C.
  • the Applicant has found that the emissivity of a polished aluminum soleplate was of the order of 0.1, while that of an enamel coating was approximately 0.8.
  • a more favorable transfer corresponding to 40 Watts is obtained when the soleplate is at 225 ° C. in the case of dry ironing, the consumption being of the order of 630 Watts during this ironing.
  • the temperature drop caused by the enamel coating is around 3 ° C, which is negligible.
  • We can therefore consider that the ironing performance with an enameled soleplate is 40/630, that is 6% better than that of a polished aluminum soleplate, not coated with enamel. This result is surprising, knowing that the enamel is thermally insulating, so that one could expect a decrease in ironing performance.
  • the soleplate 1 of an iron is made of aluminum alloy injection molded under pressure, under vacuum or in shell, such as AS 9 U 3 , ASgG, l 'AU 4 G, AS 12 or AG 5 (A denotes aluminum, S denotes silicon, U denotes copper and G denotes magnesium).
  • a resistance, armored tubular heating element 2 is embedded by overmolding.
  • the boss 3 surrounding the resistor 2 defines an interior vaporization chamber 4 and a peripheral chamber 5 for distributing the vapor. These two chambers 4, 5 are intended to be covered by a sealed cover, not shown.
  • the peripheral steam distribution chamber 5 opens to the outside via steam distribution channels 6 passing through the soleplate 1.
  • the surface 7 of the sole 1 which is intended to be applied to the articles to be ironed is covered by an enamel coating 8.
  • This enamel coating 8 is produced by projecting onto the surface 7 of the sole, an enamel frit slip which is then dried and then baked to make the mineral particles (Si0 2 and other metal oxides) contained in this slip vitrify.
  • a sintered enamel frit is used at a temperature below 500 ° C such as the frit sold by FERRO under the designation GL 43-48 which sintered at 480-490 ° C.
  • the thickness of the enamel coating 8 is generally between 20 and 100 microns.
  • Excellent adhesion of the enamel coating 8 is obtained by subjecting the surface 7 of the sole to mechanical or chemical abrasion intended to form micro-asperities or micro-cavities on this surface. It is also advantageous to apply to the surface 7 of the sole a bonding undercoat formed for example by chromating.
  • the enamel coating 8 can also partially or entirely cover the interior surface of the steam distribution channels 6, so as to limit the adhesion of the limescale formed by evaporation of the water and liable to obstruct these canals.
  • the enamel coating can be formed from two layers of enamel 8a, 8b (see Figure 2) fired simultaneously according to the process described in French patent application No. 83 06178 of April 15, 1983 in the name of the applicant, replacing the enamel frit described in this patent application by that mentioned above which sintered at 480-490 ° C.
  • At least the outer layer 8b can contain colored pigments 9 (see FIG. 2) or can be applied by screen printing if a pattern or a decoration is to be formed on the surface of the sole 1.
  • the enamel coating 8 had, taking into account its thinness, no harmful influence on the thermal conductivity of the sole. Thus, there is no need to load this enamel coating with conductive particles.
  • Figures 3 and 4 describe two examples of iron soleplate using a laminated aluminum alloy sheet.
  • the laminated alloy sheet 1a is assembled with an upper part 1b produced by injection, as in the case of the embodiment according to FIG. 1.
  • This assembly can be carried out for example by hot stamping.
  • the enamel coating 8c applied to the surface of the aluminum alloy sheet 1a can be obtained from a conventional enamel composition for aluminum, sinterable at a temperature between 500 and 600 ° C. It would of course be appropriate for the assembly to withstand this temperature.
  • the sole also comprises an aluminum alloy sheet 1c comprising an enamel coating 8d.
  • a flat resistor 10 coated in an insulating material.
  • This flat resistor 10 is pressed against the sheet 1c by means of a backing plate 11, by means of a crimping 12 carried out along the edges of the sheet 1c.
  • the invention also applies to the soles of irons in cast iron.
  • enamel coating 8, 8a, 8b, 8c could also be applied to the lateral faces of the sole.
  • the enamel coating could also cover the interior of the vaporization and steam distribution chambers 4, 5.
  • the deposit of tartar or lime in these chambers would have reduced adhesion and could therefore be removed more easily than in conventional soles.
