Definitions

  • the foundry body of an iron is a part which is generally made of aluminum on which a metal cap intended to form the ironing sole is directly attached. It is thus already known to use a stainless steel metal cap which is attached to the aluminum foundry body and fixed by means of a silicone adhesive. The binding can be improved by a peripheral attachment of the cap on the sole.
  • the production of such an ironing sole requires, prior to the fixing of the metal cap, a step of machining certain surfaces of the foundry body.
  • the production of such iron soles consequently results in a manufacturing process including steps which increase the final cost of the product.
  • it turns out due to the large differences in coefficient of thermal expansion between the aluminum foundry body and the stainless steel metal cap, that the rigidity and the very structure of the sole evolve in a negative way over time. This leads to a relative clearance between the different layers and to a thermal transmission which progressively deteriorates during use.
  • Colaminated materials are moreover obviously known, and have in particular already been used in the automotive field. To this end, we used collaminated materials of the aluminum-stainless steel bi-layer type, looking for the anti-corrosion effect of stainless steel, as well as its aesthetic appearance.
  • Colaminated materials of the aluminum-stainless steel type have also already been used to make the bottom of certain pans.
  • the thermal diffusion effect provided by aluminum has always been sought, as well as the aesthetic effect of the external stainless steel layer without worrying about the significant difference in coefficient of thermal expansion between the two colaminated materials leading to a well-known bending effect on the bottom of the pan. Because of the heating methods used and the after all minimal effect of the thermal transmittance factor for such kitchen utensils, this phenomenon of bending and relative destructuring of the bottom of the pan has always been accepted.
  • the objects assigned to the invention are also achieved by the use of a collaminated material based on at least two layers as a metal ironing cap for an iron.
  • the iron soleplate according to the invention comprises, as shown in FIG. 1, a metal cap 4 consisting of an assembly of at least two layers of colaminated materials.
  • the metal cap 4 comprises a first layer 5 which forms the fixing layer on the lower face 2 of the foundry body 1.
  • the first layer 5 is substantially flat and made of a material identical to that of the foundry body 1 or at least in a material with similar physical characteristics.
  • similar physical characteristics is meant essentially physical characteristics relating to the coefficient of thermal expansion and / or the hardness of the material and / or the thermal conductivity.
  • the co-laminated metal cap 4 also comprises a second layer 6, the external face 6a of which forms the ironing layer.
  • the foundry body will be made of aluminum, and the metal cap will comprise a two-layer collaminated assembly in which the first layer 5 is also made of aluminum, while the second layer 6 is made of stainless steel.
  • the first layer 5 can be made of a material with physical characteristics similar to aluminum, such as copper, and the second layer 6 made of copper, nickel or even titanium.
  • the metal caps thus produced will be of the aluminum-steel-stainless steel type or preferably of aluminum-copper-stainless steel or else copper-aluminum-stainless steel.
  • the relative thicknesses of the first layer 5 and the second layer 6 will each represent between 15 and 17% of the total thickness of the three-layer cap, the intermediate layer therefore representing between 66 and 70% of the total thickness.
  • the nature of the latter will obviously be chosen on the basis of criteria for improving the rigidity of the co-laminated assembly and also on criteria of thermal conductivity and expansion.
  • the metal cap 4 comprises at least one zone forming an edge folded 12 which comes to bear by its edge against a peripheral edge 13 of the foundry body 1. Due to the heterogeneity of temperatures prevailing at the level of the ironing soleplate, provision is made to produce the folded edge 12 at the front of the sole where the cap is more stressed to form a hooking nose ( Figures 2 and 3).
  • the metal cap 4 is provided over its entire perimeter with a rolled peripheral edge 14 (Figure 1) extending the second layer 6 and promoting the good mechanical strength of the sole.
  • a colaminated material based on at least two layers, preferably aluminum-stainless steel, as a metal ironing cap for an iron makes it possible to combine the advantages of the two colaminated metals.
  • the first layer 5, made of the same material or in a material similar to that of the foundry body, ensures on the one hand good thermal conduction and on the other hand an optimal fixing and bonding favorable to the stability of the whole thanks to the homogeneity of materials.
  • the second layer 6 provides a good aesthetic effect and gives the sole good gliding properties without damaging the cohesion of the colaminated assembly despite the large differences in coefficient of thermal expansion and the risks of deformation expected over the entire sole.
  • the invention finds its application in the production of iron soles, in particular of steam iron soles.
