Description
La présente invention concerne un composant chauffant plat, comprenant un élément chauffant électriquement résistant enrobé dans une matière électriquement isolante et compris entre deux plaques métalliques.The present invention relates to a flat heating component, comprising an electrically resistant heating element embedded in an electrically insulating material and comprised between two metal plates.
L'invention vise également le procédé pour la fabrication du composant chauffant précité.The invention also relates to the method for manufacturing the aforementioned heating component.
Le composant chauffant visé par l'invention peut être constitué par exemple par la semelle chauffante d'un fer à repasser ou par le fond chauffant d'un ustensile de cuisson.The heating component targeted by the invention may consist, for example, of the heating soleplate of an iron or by the heating base of a cooking utensil.
Les semelles de fer à repasser sont généralement en métal moulé tel que de l'aluminium dans lequel est enrobé une résistance chauffante électrique de forme tubulaire.The iron soles are generally made of molded metal such as aluminum in which is coated an electric heating resistor of tubular shape.
De telles semelles de fer en métal moulé sont onéreuses.Such molded metal iron soles are expensive.
On a tenté de réaliser des composants chauffants plats constitués par deux plaques métalliques entre lesquelles est intercalé un élément électriquement résistant plat enrobé dans une matière isolante.Attempts have been made to produce flat heating components consisting of two metal plates between which is inserted an electrically resistant flat element coated in an insulating material.
Ces plaques métalliques sont assemblées ensemble par rivetage ou vissage. Un tel mode d'assemblage est coûteux.These metal plates are assembled together by riveting or screwing. Such an assembly method is expensive.
Par ailleurs, l'assemblage de telles plaques métalliques pose des difficultés techniques qui n'ont pas été résolues d'une manière satisfaisante.Furthermore, the assembly of such metal plates poses technical difficulties which have not been satisfactorily resolved.
En effet, cet assemblage doit assurer un placage des deux plaques l'une sur l'autre d'une manière telle que l'on évite tout point chaud qui risquerait d'entraîner le claquage de la résistance chauffante.Indeed, this assembly must ensure a plating of the two plates one on the other in such a way that any hot spot is avoided which would risk causing the breakdown of the heating resistance.
Par ailleurs, ce placage doit être exécuté d'une manière telle que l'élément résistant soit à l'abri des agents agressifs extérieurs tels que la vapeur et l'humidité.Furthermore, this plating must be carried out in such a way that the resistant element is protected from external aggressive agents such as steam and humidity.
Le but de la présente invention est de créer un composant chauffant plat qui soit à la fois peu coûteux à fabriquer et qui remplisse les conditions exposées ci-dessus.The object of the present invention is to create a flat heating component which is both inexpensive to manufacture and which fulfills the conditions set out above.
L'invention vise ainsi un composant chauffant plat, comprenant un élément chauffant électriquement résistant enrobé dans une matière électriquement isolante et compris entre deux plaques métalliques.The invention thus relates to a flat heating component, comprising an electrically resistant heating element coated in an electrically insulating material and between two metal plates.
Suivant l'invention, ce composant est caractérisé en ce que les deux plaques métalliques sont fixées au travers de lacunes pratiquées dans l'élément chauffant et dans ladite matière isolante.According to the invention, this component is characterized in that the two metal plates are fixed through gaps made in the heating element and in said insulating material.
Ces soudures réalisées entre les deux plaques au travers de lacunes pratiquées dans l'élément chauffant, permettent d'obtenir une parfaite continuité thermique entre les deux plaques, de sorte que tout risque de claquage de l'élément résistant dû à des points chauds est évité.These welds made between the two plates through gaps made in the heating element, make it possible to obtain perfect thermal continuity between the two plates, so that any risk of breakdown of the resistant element due to hot spots is avoided. .
Selon une version avantageuse de l'invention, les deux plaques sont en métal laminé, de préférence en aluminium laminé.According to an advantageous version of the invention, the two plates are made of laminated metal, preferably of laminated aluminum.
Grâce à l'utilisation d'un métal laminé, la réalisation du composant chauffant est économique.Thanks to the use of a laminated metal, the production of the heating component is economical.
Selon une version préférée de l'invention, la soudure est réalisée par brasage, ce brasage étant obtenu par fusion d'une feuille de brasure colaminée avec l'une et/ou l'autre des deux plaques métalliques.According to a preferred version of the invention, the welding is carried out by brazing, this brazing being obtained by fusion of a sheet of brazed joint with one and / or the other of the two metal plates.
Pour réaliser le brasage, il suffit ainsi de chauffer l'ensemble jusqu'à la température de fusion de la feuille de brasure colaminée.To achieve soldering, it is sufficient to heat the assembly to the melting temperature of the colamine-coated solder sheet.
Selon un mode de réalisation avantageux de l'invention, l'une au moins des plaques présente des bossages engagés dans les lacunes de l'élément chauffant électriquement résistant, la soudure étant réalisée entre ces bossages et l'autre plaque.According to an advantageous embodiment of the invention, at least one of the plates has bosses engaged in the gaps of the electrically resistant heating element, the welding being carried out between these bosses and the other plate.
Selon au autre mode de réalisation avantageux de l'invention, l'une au moins des plaques présente une saillie s'étendant sur sensiblement toute la périphérie de la plaque, la soudure étant réalisée entre cette saillie et la périphérie de l'autre plaque.According to another advantageous embodiment of the invention, at least one of the plates has a projection extending over substantially the entire periphery of the plate, the weld being produced between this projection and the periphery of the other plate.
Cette soudure permet ainsi de réaliser l'étanchéité du composant à l'égard des agents agressifs extérieurs tels que vapeur et humidité.This welding thus makes it possible to seal the component with respect to external aggressive agents such as than steam and humidity.
Selon un autre aspect de l'invention, le procédé pour la fabrication d'un composant chauffant plat conforme à l'invention est caractérisé par les étapes suivantes:
- on dispose l'élément chauffant électrique sur la plaque comportant les bossages, en engageant ces bossages dans les lacunes de l'élément chauffant,
- on pose la seconde plaque sur l'élément chauffant,
- on chauffe l'ensemble pour obtenir la fusion de la brasure.According to another aspect of the invention, the method for manufacturing a flat heating component according to the invention is characterized by the following steps:
- the electric heating element is placed on the plate comprising the bosses, by engaging these bosses in the gaps of the heating element,
- the second plate is placed on the heating element,
- The whole is heated to obtain the fusion of the solder.
Cette opération est réalisée sans exercer de pression sur les plaques et de préférence sous vide pour éviter toute oxydation.This operation is carried out without exerting pressure on the plates and preferably under vacuum to avoid any oxidation.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Dans la réalisation des figures annexées, le composant chauffant plate, pouvant constituer le fond d'un ustensile culinaire chauffant ou une semelle de fer à repasser, comprend un élément chauffant électriquement résistant 1 comportant une feuille 2 en métal résistif découpé enrobée dans une matière électriquement isolante 3 et compris entre deux plaques métalliques 4, 5.In the embodiment of the appended figures, the flat heating component, which can constitute the bottom of a heating culinary utensil or an iron soleplate, comprises an electrically
Conformément à l'invention, les deux plaques métalliques 4, 5 sont fixées l'une à l'autre (voir figures 3 et 5) par une série de soudures 6 réalisées au travers de lacunes 7, 7a pratiquées dans l'élément chauffant résistant 1.According to the invention, the two
Les deux plaques 4, 5 sont de préférence en métal laminé et en particulier en aluminium laminé.The two
Dans la réalisation représentée, les soudures 6 sont réalisées par brasage. Ce brasage est obtenu par fusion d'une feuille de brasure 8 colaminée avec l'une et/ou l'autre des deux plaques métalliques 4, 5.In the embodiment shown, the
Dans le cas représenté, il s'agit de la plaque 5.In the case shown, it is
La plaque inférieure 5 présente des bossages 9, 9a engagés dans les lacunes 7, 7a de l'élément chauffant électriquement résistant 1. Les soudures 6 sont réalisées entre ces bossages 9, 9a et la surface 4a de l'autre plaque 4 qui est parfaitement plane.The
Par ailleurs, comme on le voit sur les figures 1, 2 et 3, la plaque 5 présente une saillie 10 s'étendant sur sensiblement toute la périphérie de la plaque, la soudure étant réalisée entre cette saillie 10 et la périphérie 4b de l'autre plaque 4.Furthermore, as can be seen in FIGS. 1, 2 and 3, the
Cette saillie 10 s'étend sur toute la périphérie de la plaque 5, à l'exception d'une zone de faible étende prévue pour le passage des connexions électriques 12, 13 de l'élément chauffant. L'étanchéité de cette zone est obtenue par d'autres moyens non représentés.This
Le feuille 2 de métal résistif de l'élément chauffant 1 est par exemple recouverte par deux feuilles de matière fibreuse telle que du papier imprégné de résine phénolique ou silicone, la liaison entre ces feuilles de matière fibreuse et la feuille de métal étant réalisée par chauffage pour assurer la polymérisation de la résine.The
Toutefois d'autres matières électriquement isolantes peuvent convenir pourvu qu'elles résistent à la température de fusion de la brasure.However, other electrically insulating materials may be suitable provided that they resist the melting temperature of the solder.
Les bossages 9, 9a peuvent être obtenus par semi-découpage de la plaque 5 au moyen de poinçons appliqués sur la face de la plaque opposée à celle où l'on veut réaliser les bossages. C'est ce qui explique la présence de cavités 11, 11a sur cette face opposée, au droit des bossages 9, 9a.The
Pour fabriquer le composant chauffant plat que l'on vient de décrire, on procède de la façon suivante :
- on dispose l'élément chauffant électrique 1 sur la plaque 5 comportant les bossages 9, 9a, 10 en engageant ces bossages dans les lacunes 7, 7a de l'élément chauffant 1,
- on pose la seconde plaque 4 sur l'élément chauffant 1,
- on chauffe l'ensemble pour obtenir la fusion de la couche de brasure 8.To manufacture the flat heating component which has just been described, the procedure is as follows:
the
- the
- the whole is heated to obtain the melting of the
De préférence, le chauffage de l'ensemble est réalisé dans une enceinte sous vide (de l'ordre de 10⁻⁵ torrs) afin d'éviter toute oxydation.Preferably, the heating of the assembly is carried out in a vacuum enclosure (of the order of 10⁻⁵ torr) in order to avoid any oxidation.
A titre d'exemple non limitatif, les deux plaques 4, 5 sont en alliage d'aluminium laminé commercialisé sous la référence 3003 par la société PECHINEY.By way of nonlimiting example, the two
La feuille de brasure 8 colaminée sur la plaque 5 peut être en alliage aluminium-silicium tel que commercialisé sous la référence 4104 par la société PECHINEY. Cette feuille de brasure 8 a un point de fusion de l'ordre de 577°C qui est inférieur à celui de l'alliage constituant les plaques 4, 5.The
Lors de la fusion de la couche de brasure 8, les tensions superficielles tendent à rapprocher énergiquement les plaques 4, 5. Après refroidissement, la pression atmosphérique s'exerçant sur les surfaces extérieures des plaques 4, 5 tend à s'opposer à toute déformation de celles-ci. De toute façon, de telles déformations sont évitées du fait de l'homogénéité du composant obtenu.During the melting of the
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and many modifications can be made to it without departing from the scope of the invention.
Ainsi, la brasure entre les plaques 4, 5 peut également être réalisée au moyen de pastilles de brasure déposées sur les bossages 9, 9a et la saillie 10.Thus, the solder between the
Les plaques 4, 5 pourraient, également être réalisées, en acier doux, acier inoxydable, cuivre, laiton, etc. pourvu que la brasure soit adaptée à ces métaux ou alliages.The
Par ailleurs, d'autres procédés de soudage pourraient être utilisés. On peut citer à ce sujet :
- la soudure par friction qui présente l'avantage de permettre une liaison simultanée en tout point des matières en contact, sans élévation notable de la température. Cependant, elle a l'inconvénient de soumettre l'élément chauffant à un sévère régime de vibration ;
- la soudure au laser ou la soudure par bombardement électronique : ces deux types de soudure donnent de bons résultats : elles ont l'avantage de pouvoir être limitées à des zones précises, soit ponctuelles, soit linéaires ;
- la soudure par ultra-sons qui est plutôt réservée à des blindages réalisés en matière thermoplastique, et aux éléments chauffants à basse température.Furthermore, other welding methods could be used. We can quote on this subject:
- friction welding which has the advantage of allowing simultaneous connection at all points of the materials in contact, without a significant rise in temperature. However, it has the disadvantage of subjecting the heating element to a severe vibration regime;
- laser welding or electron bombardment welding: these two types of welding give good results: they have the advantage of being able to be limited to precise zones, either punctual or linear;
- ultrasonic welding which is rather reserved for shields made of thermoplastic material, and heating elements at low temperature.
