    INDUCTION HEATABLE MULTI-LAYER COOKING SUPPORT
    The present invention relates to the technical field of cooking supports intended to be heated by induction, for cooking or reheating food.
    The present invention relates more particularly to multilayer cooking supports intended to be heated by induction.
    The present invention relates in particular, but not exclusively, to the cooking supports forming a cooking container.
    The present invention also relates to culinary articles comprising a cooking support associated with at least one gripping member. If desired, the gripping member (s) can be removable or removable with respect to the cooking support.
    The present invention also relates to electric cooking appliances comprising a cooking support associated with an induction heating device.
    It is known to add a ferritic stainless steel grid under the bottom of a metal plate to form a cooking vessel which can be heated by induction. The metal plate is for example made of aluminum. Such an embodiment uses a cold stamping operation to assemble the grid with the metal plate, before shaping the assembly by stamping.
    It is also known to assemble a ferritic stainless steel plate with a tank using an aluminum intermediate plate to form a cooking vessel having a diffuser bottom.
    It is also known to use a two-layer or three-layer laminated material comprising a layer of aluminum laminated with one or two layers of stainless steel, to produce a multilayer cooking vessel.
    A disadvantage of these achievements is that they remain relatively expensive.
    An object of the present invention is to provide a multilayer cooking support compatible with an induction heating device, the production of which is more economical.
    Another object of the present invention is to provide a process for obtaining a multilayer cooking support compatible with an induction heating device, which is more economical.
    These objects are achieved with a cooking support that can be heated by induction, having an upper cooking face and a lower heating face, the cooking support comprising a laminated structure comprising a thermal diffusion layer, if desired coated, to form the upper baking surface, and a layer of ferromagnetic material, because the layer of ferromagnetic material is made of non-stainless steel, and that the laminated structure includes a protective metal layer covering the layer of ferromagnetic material on the side opposite the layer thermal diffusion. Using a layer of ferromagnetic material other than stainless steel can significantly reduce the cost of the cooking medium. The use of a laminated structure comprising a protective metal layer makes it possible to protect the surface of the layer of ferromagnetic material, in particular from corrosion, but also to preserve the electromagnetic coupling between the ferromagnetic material and an induction heating furnace.
    Advantageously then, the layer of ferromagnetic material is produced in a shade of carbon steel suitable for forming by stamping at room temperature. This arrangement makes it possible to obtain an economical construction.
    Advantageously then, the layer of ferromagnetic material is produced in a steel grade comprising from 0.12 to 0.08% by mass of carbon and from 0.6 to 0.35% by mass of manganese.
    Advantageously still, the thickness of the thermal diffusion layer is greater than the thickness of the layer of ferromagnetic material. This arrangement improves the thermal uniformity of the upper cooking surface.
    Advantageously also, the thermal diffusion layer is made of aluminum or an aluminum alloy. This arrangement makes it possible to obtain an economical construction.
    According to one embodiment, the protective metal layer is formed by an aluminum strip co-laminated with the layer of ferromagnetic material on the side opposite to the thermal diffusion layer. Such a protective metallic layer is suitable for forming by stamping at ambient temperature. The three layers are for example co-laminated at the same time, such an embodiment has an economical construction and a simple implementation.
    Advantageously then, the protective metallic layer has an average thickness less than or equal to 10 μm, and preferably less than or equal to 8 μm. Aluminum having a paramagnetic character, an excessively large thickness leads to coupling faults with certain induction heaters.
    According to another embodiment, the protective metal layer is formed by an electrolytic nickel coating. Such a protective metal layer is also suitable for forming by stamping at room temperature.
    Advantageously then, the protective metallic layer has a thickness of between 2 and 30 μm, and preferably between 4 and 15 μm. Due to the ferromagnetic nature of nickel, the thickness of the protective metal layer can be thicker with an electrolytic nickel coating than with an aluminum strip.
    Advantageously, another metal protective layer covers the layer of ferromagnetic material on the side of the thermal diffusion layer. This arrangement facilitates the production of the protective metal layer by immersing the layer of ferromagnetic material in an electrolytic bath without the need to protect the other face of the layer of ferromagnetic material.
    Advantageously then, the other protective metallic layer is formed by another coating of electrolytic nickel. The protective metal layer and the other protective metal layer can thus be obtained with the same operation.
    Advantageously also, the other protective metallic layer has a thickness of between 2 and 30 μm, and preferably between 4 and 15 μm.
    Advantageously also, the thermal diffusion layer has a thickness of between 0.5 and 6 mm, and preferably between 1 and 1.5 mm.
    Advantageously also, the layer of ferromagnetic material has a thickness of between 0.15 and 1 mm, and preferably between 0.25 and 0.6 mm.
    Advantageously also, the thermal diffusion layer carries a coating forming the upper baking surface, in particular a PTFE coating, or a ceramic coating, or an enamel coating.
    According to one embodiment, the cooking support has a bottom surrounded by a side wall to form a cooking container.
    These objects are also achieved with a culinary article comprising a cooking support having a gripping member, in which the cooking support conforms to at least one of the above characteristics.
    These objects are also achieved with an electric cooking appliance comprising a cooking support associated with an induction heating hearth, in which the cooking support conforms to at least one of the above characteristics.
    These objects are also achieved with a process for obtaining a cooking medium according to at least one of the above characteristics, comprising the following steps:
    cutting or supplying a shape from a colaminated strip comprising the thermal diffusion layer, the layer of ferromagnetic material and the protective metal layer, stamping the shape to form a cooking support comprising the upper cooking side of the thermal diffusion layer and the underside of heating on the side of the protective metal layer.
    Advantageously then, the form is a disc.
    The invention will be better understood from the study of four exemplary embodiments, taken without any limitation being implied, illustrated in the appended figures, in which:
    FIG. 1 is a view in elevation and in vertical section of a first embodiment of a multilayer cooking support according to the invention, the thicknesses of the different layers not being shown to scale, FIG. 2 is an enlarged view of a part of FIG. 1, FIG. 3 is a schematic view in elevation and in vertical section of a part of a second embodiment of a multilayer cooking support according to the invention, the thicknesses different layers not being shown to scale either, FIG. 4 is a schematic view in elevation and in vertical section of an exemplary embodiment of a culinary article comprising a multilayer cooking support according to the invention, Figure 5 is a schematic view in elevation and in vertical section of an embodiment of an electric cooking appliance comprising a multilayer cooking support according to the invention ntion.
    The cooking support 1 illustrated in FIG. 1 has an upper cooking face 2 intended to receive the food to be cooked and a lower heating face 3 intended to be heated, in particular by resting on an induction heating hearth.
    In the embodiment illustrated in FIG. 1, the cooking support 1 has a bottom 4 surrounded by a side wall 5 to form a cooking container 7. The side wall 5 rises to an upper edge 6.
    The cooking support 1 is a multilayer cooking support compatible with induction heating. The cooking support 1 comprises a multilayer colaminated structure.
    The cooking support 1 comprises a thermal diffusion layer 11 forming or carrying the upper cooking face 2. The cooking support 1 comprises a layer of ferromagnetic material 12 co-laminated with the thermal diffusion layer 11.
    The thermal diffusion layer 11 is preferably made of aluminum or an aluminum alloy. Alternatively, other materials that are good conductors of heat could be considered, such as copper in particular. However, such a material turns out to be quite expensive.
    The thermal diffusion layer 11 can in particular carry an upper coating 10 forming the upper baking surface 2. The upper coating 10 can in particular be a PTFE coating, or a ceramic coating, or an enamel coating. If desired, the top coating 10 can have several layers. Alternatively, the thermal diffusion layer 11 can form the upper baking surface 2. If desired, the thermal diffusion layer 11 can have a surface treatment, such as for example anodization.
    The layer of ferromagnetic material 12 is made of non-stainless steel, such a material being more economical than stainless steel. The layer of ferromagnetic material 12 made of non-stainless steel is advantageously made of carbon steel. The layer of ferromagnetic material 12 of non-stainless steel is preferably produced in a shade of carbon steel suitable for forming by stamping at room temperature. The steel grades called DD11, DD12, DD13 or DD14, comprising from 0.12 to 0.08% by mass of carbon and from 0.6 to 0.35% by mass of manganese, are for example well suited for producing the layer of ferromagnetic material 12.
    The layer of ferromagnetic material 12 is covered by a protective metallic layer 13 forming or carrying the bottom heating face 3. The protective metallic layer 13 must make it possible to protect the external face of the layer of ferromagnetic material 12 made of non-stainless steel . The upper edge 6 of the cooking container 7 may in particular be left free from any protection, as shown in FIG. 1, or else be turned over to hide the possible appearance of corrosion.
    In the embodiment illustrated in FIGS. 1 and 2, the cooking support 1 comprises a 3-layer collaminated structure comprising the thermal diffusion layer 11, the layer of ferromagnetic material 12, and the protective metallic layer 13. The thermal diffusion layer 11 may have a thickness of between 1 and 5 mm. The layer of ferromagnetic material 12 can have a thickness of the order of 0.25 mm. Thus, the thickness of the thermal diffusion layer 11 is greater than the thickness of the layer of ferromagnetic material 12.
    In the embodiment illustrated in FIGS. 1 and 2, the protective metal layer 13 is formed by an aluminum strip co-laminated with the layer of ferromagnetic material 12 and the thermal diffusion layer 11. The protective metal layer 13 must allow an inductive coupling of the layer of ferromagnetic material 12 with the induction heating hearth on which the cooking support is placed 1. For this purpose it has been observed that when the protective metal layer 13 has an average thickness less than 10 pm, the coupling of the cooking support 1 with the induction heating hearth is rather good. In addition, when the protective metal layer 13 has an average thickness of less than 8 μm, no coupling fault between the cooking support 1 and the induction heating furnace has been observed.
    Thus, the average thickness of the protective metal layer 13 is less than the thickness of the layer of ferromagnetic material 12 and the thickness of the thermal diffusion layer 11. If desired, the protective metal layer 13 can wear a coating, not shown in the figures, forming the underside of the heater 3.
    The exemplary embodiment illustrated in FIG. 3 differs from the exemplary embodiment illustrated in FIGS. 1 and 2 in that the cooking support T comprises a 2-layer laminated structure comprising a thermal diffusion layer 11 ′ and a layer of ferromagnetic material 12 ', the layer of ferromagnetic material 12' being coated on the side of the heating underside 3 'with a protective metal layer 13' formed by an electrolytic nickel coating and on the side of the heat diffusion layer 11 'by another protective metal layer 14' formed by another coating of electrolytic nickel. The thermal diffusion layer 11 'forms or carries the upper cooking surface 2'. The cooking support T may have a bottom surrounded by a side wall to form a cooking container 7 ’.
    The thermal diffusion layer 11 ′ can have a thickness of between 1 and 5 mm, advantageously of the order of 1 mm. The other metal protective layer 14 ′ can have a thickness of between 2 and 30 μm, and preferably between 4 and 15 μm, advantageously of the order of 5 μm. The layer of ferromagnetic material 12 ’can have a thickness of the order of 0.5 mm. The protective metal layer 13 ′ can have a thickness of between 2 and 30 μm, and preferably between 4 and 15 μm, advantageously of the order of 5 μm.
    Thus, the multilayered laminated structure of the cooking support 1 or of the cooking container 7 comprises three laminated layers (thermal diffusion layer 11, layer of ferromagnetic material 12, and protective metallic layer 13), and the multilayered laminated structure of the cooking support. 1 ′ or of the cooking container 7 ′ has two co-laminated layers (thermal diffusion layer 11 ′, and layer of ferromagnetic material 12 ′ coated on one side with the protective metallic layer 13 ′ and on the other side with the another protective metal layer 14 '). If desired, the thermal diffusion layer 11; 11 ’can have a top coating 10; 10 'forming the upper cooking surface 2; 2 '.
    The invention also relates to a process for obtaining a cooking support 1; 1 ’with the following steps:
    Cutting or supplying a shape from a laminated strip comprising the thermal diffusion layer 11; 11 ’, the layer of ferromagnetic material 12; 12 ’and the protective metal layer 13; 13 ’, the shape being advantageously a disc,
    Stamping of the form to form the cooking support 1; 1 ’with the upper cooking surface 2; 2 'on the side of the thermal diffusion layer 11; 11 ’and the underside of the heater 3; 3 'on the side of the protective metal layer 13; 13 '.
    If desired, the process for obtaining the cooking support 1; 1 ’may include at least one subsequent step consisting in producing an upper coating forming the upper cooking surface 2; 2 ’and / or to produce a lower covering forming the lower heating face 3; 3 '.
    If desired, the process for obtaining the cooking support 1 may include a step of brushing the free face of the protective metal layer 13 formed by the aluminum strip, to favor the attachment of a lower coating forming the lower face of heater 3. This arrangement contributes to reducing the thickness of the protective metal layer 13, which is favorable for obtaining a good coupling with the induction heater used to heat the cooking container 7. As alternatively, methods other than brushing can be envisaged for mechanically or chemically attacking the free face of the protective metal layer 13 formed by the aluminum strip, to promote the attachment of a lower coating forming the lower heating face 3.
    FIG. 4 illustrates a culinary article 100 comprising a cooking support 1 "having a gripping member 102. The cooking support 1" corresponds to the cooking support 1 or to the cooking support Γ. The cooking support 1 ”has an upper cooking face 2” intended to contain the food to be cooked and a lower heating face 3 ”intended to be heated, in particular by resting on an induction heating hearth.

If desired, another gripping member 104 can be fixed to the 5 "side wall of the cooking container 7" by means of at least one other rivet 105, by welding or by screwing on a stud welded to the 5 "side wall.
    FIG. 5 illustrates an electric cooking appliance 200, comprising a cooking support Γ ”associated with an induction heating hearth 250. The cooking support Γ” corresponds to the cooking support 1 or to the cooking support T. In the example of embodiment illustrated in FIG. 5, the cooking support T ”has a bottom 4 '” surrounded by a side wall 5' ”to form a cooking container 7 '”. The 7 '”cooking container is arranged in a heating base 210 comprising the induction heating furnace 250. The 7'” cooking container has a bottom 3 '”heating surface resting on the induction heating furnace 250, and a 2 '”upper cooking surface. If desired, the 7 '”cooking container may include a gripping member 202 and / or another gripping member 204, for example fixed by at least one rivet 203 or by at least one other rivet 205, or by welding or by screwing. on a stud welded to the 5 '”side wall.
    As a variant, the cooking support 1; T; 1 ”; T ”does not necessarily form a cooking container 7; 7 '; 7 ”; 7 ". The cooking support 1; 1 '; 1 ”; 1 "p t been particularly form a hotplate.
