Abstract

The saucepan or frying pan is made in aluminium or else has a base made in aluminium. The base is covered with a layer of metal or a metallic alloy which is harder than aluminium. This is formed by projecting small drops of metal on to the base which fuse on to it. The outer surface of the layer is smooth, or it can be covered with a layer of paint or enamel. The metal is preferably stainless steel or a ferromagnetic alloy.

Description

La présente invention concerne les ustensiles ménagers de cuisson, tels que casserole, poêle, fait-tout.etc.... en aluminium ou comportant un fond en aluminium. The present invention relates to household cooking utensils, such as saucepan, frying pan, casserole, etc., made of aluminum or having an aluminum base.

L'aluminium est un métal relativement mou et, pour les protéger et les renforcer, il est connu d'incorporer au fond de ces ustensiles une tôle ou une grille en un métal ou alliage ayant une dureté supérieure à celle de l'aluminium; éventuellement, cette tôle ou grille lorsqu'elle est en un métal ou alliage ferromagnétique, permet d'utiliser ces ustensiles sur des plaques de cuisson à induction. Aluminum is a relatively soft metal and, to protect and strengthen them, it is known to incorporate at the bottom of these utensils a sheet or grid made of a metal or alloy having a hardness greater than that of aluminum; optionally, this sheet or grid when it is made of a metal or ferromagnetic alloy, allows these utensils to be used on induction hobs.

Diverses solutions ont été proposées pour fixer la tôle ou la grille sur le fond de l'ustensile, mais aucune ne donne satisfaction car les contraintes résultant des différences de dilatation du fond en aluminium et de l'élément de renfort qui apparaissent à chaque cycle de chauffage-refroidissement entrainent rapidement la déformation du fond de l'ustensile et, à plus ou moins long terme. une rupture des liaisons entre le fond et l'élément de renfort. Various solutions have been proposed for fixing the sheet or the grid to the bottom of the utensil, but none is satisfactory because the constraints resulting from the differences in expansion of the aluminum bottom and of the reinforcing element which appear at each cycle of heating-cooling quickly cause the bottom of the cookware to deform and, in the more or less long term. a break in the connections between the bottom and the reinforcing element.

Le but de la présente invention est de foumir un moyen de renforcer le fond en aluminium d'un ustensile de cuisson et de rendre cet ustensile apte à être chauffé par induction qui ne présente pas les inconvénients des solutions connues et confère à l'ustensile une durée de vie prolongée. The object of the present invention is to provide a means of strengthening the aluminum base of a cooking utensil and making this utensil suitable for being heated by induction which does not have the drawbacks of known solutions and gives the utensil a extended service life.

L'ustensile de cuisson objet de la présente invention est caractérisé en ce que son fond est revétu extérieurement d'une couche d'un métal ou alliage plus dur que l'aluminium formée par projection de gouttelettes du métal ou de l'alliage en fusion. Cette couche pourra être usinée pour obtenir une surface lisse et plane. Elle pourra aussi être revétue d'une peinture ou d'un émail. The cooking utensil object of the present invention is characterized in that its bottom is coated on the outside with a layer of a metal or alloy harder than aluminum formed by spraying droplets of the molten metal or alloy . This layer can be machined to obtain a smooth and flat surface. It can also be coated with a paint or an enamel.

Pour former la couche de renfort on utilisera les méthodes connues de métallisation par projection, à l'aide d'un pistolet, de gouttelettes de métal en fusion. To form the reinforcing layer, known methods of metallization by spraying, using a gun, using droplets of molten metal will be used.

Le métal choisi pour constituer cette couche de renfort pourra être de l'acier inoxydable. Si l'ustensile doit être utilisé sur un appareil de chauffage à induction, on choisira un métal ou alliage ferromagnétiq ue.  The metal chosen to constitute this reinforcing layer may be stainless steel. If the utensil is to be used on an induction heater, a ferromagnetic metal or alloy will be chosen.

La couche de renfort pourra être usinée pour obtenir une surface d'appui lisse ne risquant pas d endommager les plaques de cuisson. The reinforcing layer can be machined to obtain a smooth support surface which does not risk damaging the cooking plates.

La couche de renfort pourra aussi être revétue d'une couche de peinture ou d'émail. Dans ce cas. la rugosité de la couche de renfort. propre à son mode de formation . permettra d obtenir un très bonne adhérence de la peinture ou de l'émail.  The reinforcing layer may also be coated with a layer of paint or enamel. In that case. the roughness of the reinforcing layer. specific to his training mode. will allow very good adhesion of the paint or enamel.

Invention s'applique à tous les ustensiles ménagers de cuisson en aluminium, quel que soit leur mode de fabrication. par moulage ou emboutissage. ainsi qu'aux ustensiles comportant un fond en aluminium rapporté.  The invention applies to all household aluminum cooking utensils, whatever their manufacturing method. by molding or stamping. as well as utensils with an added aluminum base.
