Description

La présente invention concerne le domaine des équipements électro-ménagers, en particulier des radiateurs de chauffage électrique, et a pour objet un panneau chauffant en verre.The present invention relates to the field of household appliances, in particular electric heating radiators, and relates to a glass heating panel.

Il existe actuellement des radiateurs électriques dits à panneau radiant, dont la source de chaleur est constituée par un panneau en verre épais, généralement de l'ordre de 8 mm d'épaisseur, gui est pourvu sur sa face arrière d'un circuit résistif sérigraphié, à base de pâte d'argent, ce circuit étant pourvu à ses extrémités de cosses d'alimentations. Ces panneaux connus sont généralement montés dans un boîtier pourvu d'un thermostat de réglage et de fils d'alimentation et constituant un radiateur mural. De tels radiateurs présentent une puissance maximale limitée à environ 2000 W.There are currently so-called electric radiators with a radiant panel, the heat source of which consists of a thick glass panel, generally of the order of 8 mm thick, which is provided on its rear face with a screen-printed resistive circuit. , based on silver paste, this circuit being provided at its ends with power terminals. These known panels are generally mounted in a housing provided with an adjustment thermostat and supply wires and constituting a wall radiator. Such radiators have a maximum power limited to around 2000 W.

Ces panneaux connus présentent, cependant, l'inconvénient de gradients thermiques élevés entre les parties du verre chauffées par le circuit résistif et celles s'étendant entre les spires du circuit résistif, ce gui entraîne un risque important de casse des panneaux et explique la nécessité de réaliser lesdits panneaux en un verre épais afin d'obtenir une meilleure résistance mécanique. Il en résulte que ces panneaux sont d'un prix de revient élevé et d'un poids important, ce gui est un handicap pour une installation à grande échelle.These known panels have, however, the disadvantage of high thermal gradients between the parts of the glass heated by the resistive circuit and those extending between the turns of the resistive circuit, this mistletoe involves a significant risk of breakage of the panels and explains the need to produce said panels in thick glass in order to obtain better mechanical resistance. As a result, these panels are of a high cost price and of a significant weight, this mistletoe is a handicap for a large-scale installation.

En outre, le procédé d'obtention du circuit résistif par sérigraphie d'un conducteur suivant un tracé donné ne permet pas d'obtenir une bonne maîtrise de la résistance de ce circuit, dont les variations sont comprises entre + 5 % et - 10 %.In addition, the process for obtaining the resistive circuit by screen printing of a conductor along a given path does not make it possible to obtain good control of the resistance of this circuit, the variations of which are between + 5% and - 10% .

Enfin, sur les panneaux chauffants connus, la résistance est parfaitement visible sur le verre, ce gui nuit à l'esthétique des panneaux et empêche toute utilisation annexe desdits panneaux, notamment comme supports d'éléments décoratifs.Finally, on known heating panels, the resistance is perfectly visible on the glass, this mistletoe affects the aesthetics of the panels and prevents any use. annex to said panels, in particular as supports for decorative elements.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un panneau chauffant en verre caractérisé en ce qu'il est pourvu sur l'une de ses faces d'une couche de fond homogène résistive servant de circuit chauffant et de plots d'alimentation ou de bandes conductrices, pour un raccordement ou un soudage de fils conducteurs, la couche de fond et, éventuellement, les bandes conductrices étant recouvertes d'une couche de revêtement isolant.It has, in fact, for its object a glass heating panel characterized in that it is provided on one of its faces with a homogeneous resistive base layer serving as a heating circuit and supply pads or conductive strips , for connecting or welding conductive wires, the base layer and, optionally, the conductive strips being covered with an insulating coating layer.

L'invention sera mieux comprise, grâce à la description ci-après, gui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence au dessin schématique annexé, dans lequel :

  • la figure 1 est une vue en plan d'un panneau conforme à l'invention, et
  • les figures 2 et 3 sont des vues analogues à celles de la figure 1 de variantes de réalisation de l'invention.
The invention will be better understood, thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawing, in which:
  • FIG. 1 is a plan view of a panel according to the invention, and
  • Figures 2 and 3 are views similar to those of Figure 1 of alternative embodiments of the invention.

Conformément à l'invention et comme le montrent les figures 1 à 3 du dessin annexé, le panneau chauffant en verre est avantageusement pourvu sur l'une de ses faces d'une couche de fond homogène 1 résistive servant de circuit chauffant et de plots d'alimentation 2 ou de bandes conductrices 3, pour un raccordement ou un soudage de fils conducteurs 4, la couche 1 et, éventuellement, les bandes conductrices 3 étant recouvertes d'une couche 5 de revêtement isolant.In accordance with the invention and as shown in FIGS. 1 to 3 of the appended drawing, the glass heating panel is advantageously provided on one of its faces with a homogeneous resistive base layer 1 serving as a heating circuit and pads 'supply 2 or conductive strips 3, for a connection or welding of conductive wires 4, the layer 1 and, optionally, the conductive strips 3 being covered with a layer 5 of insulating coating.

Une telle disposition d'une couche homogène résistive 1 permet de réduire sensiblement les gradients thermiques dans la plaque support en verre et ainsi d'en améliorer la résistance à la casse.Such an arrangement of a homogeneous resistive layer 1 makes it possible to substantially reduce the thermal gradients in the glass support plate and thus to improve their resistance to breakage.

En outre, l'homogénéité de la couche 1 permet l'obtention d'une grande précision de la puissance de chauffage et d'un panneau chauffant parfaitement fiableIn addition, the homogeneity of the layer 1 allows obtaining a high precision of the heating power and a perfectly reliable heating panel.

La couche de fond résistive 1 est avantageusement une couche d'oxyde d'étain ou d'argent ou d'autre matériau conducteur déposée par sérigraphie, par pyrolyse ou par pulvérisation et les bandes conductrices 3 sont également réalisées sous forme de bandes en oxyde d'argent permettant le soudage de fils conducteurs 4.The resistive base layer 1 is advantageously a layer of tin or silver oxide or other conductive material deposited by screen printing, by pyrolysis or by spraying and the conductive strips 3 are also produced in the form of strips of oxide d silver for welding conductive wires 4.

La couche 5 de revêtement isolant est constituée, de préférence, par un vernis époxy.The layer 5 of insulating coating preferably consists of an epoxy varnish.

Selon une variante de réalisation de l'invention représentée à la figure 2, la couche de fond résistive 1 est avantageusement découpée en zones par des lignes de découpe 6. Un tel mode de réalisation permet l'obtention de zones pouvant être associées en série ou en parallèle, dans le but d'obtenir une valeur de résistance particulière pour un panneau de géométrie donnée, sans influencer pour autant les faibles gradients thermiques existants, l'alimentation électrique étant réalisée par des plots 2 à mise sous tension individuelle disposés le long d'un côté du panneau et coopérant avec une bande conductrice 3 s'étendant le long du côté opposé, chaque zone délimitée par les découpes 6 étant pourvue d'un plot 2.According to an alternative embodiment of the invention shown in FIG. 2, the resistive base layer 1 is advantageously cut into zones by cutting lines 6. Such an embodiment makes it possible to obtain zones which can be associated in series or in parallel, in order to obtain a particular resistance value for a panel of given geometry, without however influencing the low existing thermal gradients, the electrical supply being carried out by pads 2 with individual energization arranged along d one side of the panel and cooperating with a conductive strip 3 extending along the opposite side, each zone delimited by the cutouts 6 being provided with a stud 2.

Les lignes 6 de découpe de la couche résistive 1 sont des lignes très fines, quasiment invisibles sur le panneau en position montée.The lines 6 for cutting the resistive layer 1 are very thin lines, almost invisible on the panel in the mounted position.

La figure 3 représente une autre variante de réalisation de l'invention, dans laquelle la couche de fond résistive 1 est complétée par des plots 7 également en matière résistive, disposés à intervalles réguliers sur ladite couche 1. Ces plots peuvent également être remplacés par des alvéoles sans matière dans la couche résistive.FIG. 3 represents another variant embodiment of the invention, in which the resistive base layer 1 is completed by studs 7 also made of resistive material, arranged at regular intervals on said layer 1. These studs can also be replaced by cells without material in the resistive layer.

De tels plots 7 sont destinés à augmenter la résistance électrique de la couche résistive 1 et donc à adapter la puissance de chauffage du panneau conforme à l'invention.Such pads 7 are intended to increase the electrical resistance of the resistive layer 1 and therefore to adapt the heating power of the panel according to the invention.

Du fait de l'obtention d'un gradient de température pafaitement uniforme, il est possible d'utiliser un panneau en verre de support de moindre épaisseur, et donc d'un prix de revient moindre.Due to the obtaining of a uniformly smooth temperature gradient, it is possible to use a support glass panel of lesser thickness, and therefore of a lower cost price.

En outre, cette uniformité du gradient de température permet une amélioration de la fiabilité du panneau chauffant obtenu, et donc une réduction des rebuts de fabrication, ce gui influence également de manière favorable le prix de revient.In addition, this uniformity of the temperature gradient allows an improvement in the reliability of the heating panel obtained, and therefore a reduction in manufacturing waste, this mistletoe also favorably influences the cost price.

Selon une autre caractéristique de l'invention, non représentée au dessin annexé, la couche de fond résistive 1 peut également constituer une couche de fond pour un décor apposé sur la face correspondante ou sur l'autre face du panneau formant la plaque support.According to another characteristic of the invention, not shown in the accompanying drawing, the resistive base layer 1 can also constitute a base layer for a decoration affixed to the corresponding face or to the other face of the panel forming the support plate.

Ainsi, il est possible de réaliser des panneaux chauffants décorés, intégrant parfaitement le circuit résistif, gui est alors totalement invisible, contrairement aux modes de réalisation des panneaux existant actuellement.Thus, it is possible to produce decorated heating panels, perfectly integrating the resistive circuit, which is then completely invisible, unlike the embodiments of the panels currently existing.

Enfin, du fait que le panneau de verre peut présenter une épaisseur notablement réduite par rapport à celle des panneaux utilisés à ce jour, il est possible de réaliser des radiateurs mureaux de très faible épaisseur, dont l'intégration dans l'habitat peut s'effectuer de manière plus harmonieuse.Finally, since the glass panel can have a significantly reduced thickness compared to that of the panels used to date, it is possible to produce very thin wall radiators, the integration of which into the home can be perform more harmoniously.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
