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 soles of iron, dry or steam, are currently made of aluminum alloy molded in particular by pressure injection (see for example FR-E-57 460 and US-A-3 333 955).
  • 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 aforementioned embodiment of a conventional sole made of aluminum alloy molded in one piece constitutes a good solution of the problem of fixing the tubular heating resistance to the soleplate of the iron, and it makes it possible to obtain good heat exchange between the heating resistance and the aluminum alloy, without any deformation of the sole.
  • a metal sheet is compatible with a thin planar heating resistance, but not with a tubular resistance.
  • GB-A-1 380 415 describes an iron according to the characteristics of the preamble of claim 1.
  • the object of the present invention is to remedy all the aforementioned drawbacks.
  • the invention thus relates to an iron soleplate, according to the subject of claim 1.
  • this enamel coating effectively protects the soleplate against oxidation caused by water vapor and other chemicals.
  • the stains caused by limescale 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 makes it possible to substantially reduce the sliding coefficient of the soleplate on the articles to be ironed, which allows users to iron effortlessly. This property is surprising since it does not result from the known properties of enamel coatings. This explains, moreover, the reason why enamel coatings have never been used to improve the slip coefficient. In addition, this enamel coating resists mechanical shock and therefore avoids the use of protection provisional. It also makes it possible to use less expensive alloys for the sole and to replace the costly polishing of the sole, by simple mechanical abrasion using an abrasive cloth.
  • 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 first part of 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 gives the surface of the sole a largely sufficient hardness.
  • the aforementioned drawback is eliminated by applying the enamel coating in the form of a sintered enamel frit at a temperature between 500 ° C and 600 ° C, not directly on the cast aluminum alloy, but on the second part, consisting of a laminated aluminum sheet attached to the aforementioned aluminum alloy.
  • the soleplate 1 of the iron is made of aluminum alloy injection molded under pressure, under vacuum or in shell, such as AS9U3, AS9G, AU4G, AS12 or AG5 (A denotes aluminum, S denotes silicon, U denotes copper and G denotes magnesium).
  • AS9U3, AS9G, AU4G, AS12 or AG5 A denotes aluminum, S denotes silicon, U denotes copper and G denotes magnesium.
  • an armored tubular heating resistance 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 out to the outside via steam distribution channels 6 passing through the soleplate 1.
  • the surface 7 of the soleplate, 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 fired to make the mineral particles (SiO2 and other metal oxides) contained in this slip vitrify.
  • the thickness of the enamel coating 8 is generally between 20 and 100 microns.
  • the enamel coating can be formed from two layers of enamel 8a, 8b (see FIG. 2) fired simultaneously according to the process described in French patent application No. 8,306,178 of April 15, 1983 in the name of the applicant, in replacing the enamel frit described in this patent application by the one 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.
  • FIG. 3 describes an example of an 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 realization according to the Figure 1.
  • This assembly can be done 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, which can be sintered at a temperature of between 500 and 600 ° C. of course the assembly supports this temperature.
