Description
La présente invention concerne un appareil de chauffage électrique, de préférence à poste fixe comprenant un bâti principal dans lequel est monté d'une part au moins un élément chauffant incluant un circuit résistif , ledit élément étant associé à une plaque support solidaire du bâti, et d'autre part au moins une plaque de rayonnement formant la façade de l'appareil ladite plaque étant solidaire du bâti et montée à distance de l'élément chauffant.The present invention relates to an electric heating device, preferably a stationary station comprising a main frame in which is mounted on the one hand at least one heating element including a resistive circuit, said element being associated with a support plate integral with the frame, and on the other hand at least one radiation plate forming the front of the device, said plate being integral with the frame and mounted at a distance from the heating element.
Les appareils de chauffage électrique du type mentionné précédemment peuvent être considérés comme assurant de manière simultanée à la fois un chauffage par convection naturelle et par rayonnement à partir de la plaque de rayonnement située à l'avant de l'appareil. Un tel type d'appareil est bien connu et se compose en général d'un bâti métallique incluant au moins la face arrière de l'appareil qui est destiné à être fixé à poste fixe sur un mur d'habitation par exemple. L'élément de chauffe est constitué de manière connue en soi par une plaque en tôle émaillée sur laquelle est imprimée une piste résistive. La face avant de l'appareil est constituée en général par une grille rapportée, à distance de la tôle émaillée, sur les faces latérales du bâti. De tels appareils mettent en oeuvre des éléments résistifs haute-température de l'ordre de 350 °C au niveau de la piste résistive, et dans tous les cas supérieure à 300 ° C. Pour pouvoir satisfaire aux différentes contraintes normatives imposées sur ce type d'appareil, et en particulier pour éviter de dépasser une valeur de température limite de l'ordre de 80 à 100 ° C au niveau de la grille formant le panneau avant, il est nécessaire de créer intérieurement au bâti une convection naturelle. Ceci ne peut être obtenu qu'en ménageant une distance suffisante entre la tôle émaillée et le panneau avant. Un premier inconvénient de ce type d'appareil est donc, outre la nécessité d'avoir recours à des éléments résistifs de prix élevé, la réalisation d'appareil de chauffage de type mural, présentant une épaisseur relativement élevée de l'ordre d'au moins 70 mm. Il doit également être noté que le recours à des éléments résistifs obtenus par pistes résistives imprimées sur émail ne présente pas les garanties de sécurité nécessaires en matière d'isolation électrique. L'épaisseur importante de tels appareils est bien évidemment perçue de manière négative par l'utilisateur en raison de l'encombrement en résultant.Electric heating devices of the type mentioned above can be considered to simultaneously provide both natural convection and radiation heating from the radiation plate located at the front of the device. Such a type of device is well known and generally consists of a metal frame including at least the rear face of the device which is intended to be fixed to a fixed post on a residential wall for example. The heating element is constituted in a manner known per se by an enamelled sheet plate on which is printed a resistive track. The front face of the device generally consists of an attached grid, at a distance from the enamelled sheet, on the lateral faces of the frame. Such devices use high-temperature resistive elements of the order of 350 ° C at the level of the resistive track, and in all cases greater than 300 ° C. To be able to satisfy the various normative constraints imposed on this type of 'device, and in particular to avoid exceeding a limit temperature value of the order of 80 to 100 ° C at the grid forming the front panel, it is necessary to create internally to the frame a natural convection. This can only be obtained by leaving a sufficient distance between the enamelled sheet and the panel. before. A first drawback of this type of appliance is therefore, in addition to the need to have recourse to resistive elements of high price, the production of wall-type heating appliance, having a relatively high thickness of the order of at least minus 70 mm. It should also be noted that the use of resistive elements obtained by resistive tracks printed on enamel does not provide the necessary safety guarantees in terms of electrical insulation. The large thickness of such devices is obviously perceived negatively by the user due to the resulting bulk.
Il a déjà été proposé pour tenter de résoudre le problème de l'échauffement important de la grille extérieure des appareils décrits précédemment, de remplacer cette dernière par un matériau d'effusivité thermique plus faible, par exemple à base de verre. Cependant pour maintenir une puissance de chauffe sensiblement équivalente il s'est avéré nécessaire d'inclure dans cette même plaque de verre un élément résistif additionnel sérigraphié. En outre il n'est pas inutile de remarquer que le recours à une plaque de verre pourvue d'une résistance additionnelle augmente de manière sensible le coût global de tels appareils.It has already been proposed in an attempt to solve the problem of the significant heating of the external grid of the devices described above, to replace the latter with a material of lower thermal effusivity, for example based on glass. However, in order to maintain a substantially equivalent heating power, it has proved necessary to include in this same glass plate an additional screen-printed resistive element. In addition, it is worth noting that the use of a glass plate provided with an additional resistance appreciably increases the overall cost of such devices.
Il est en outre connu, par l'intermédiaire du document FR-A-2172761, de réaliser un appareil de chauffage électrique comprenant un bâti principal dans lequel est monté, d'une part un élément chauffant incluant un circuit résistif, ledit élément chauffant étant noyé dans une couche de ciment, solidaire du bâti et pourvue d'un élément dissipateur thermique, et d'autre part, un panneau formant une façade de l'appareil solidaire du bâti et monté à distance de l'élément chauffant, l'élément dissipateur thermique étant noyé partiellement dans la couche de ciment.It is also known, through document FR-A-2172761, to produce an electric heating device comprising a main frame in which is mounted, on the one hand, a heating element including a resistive circuit, said heating element being embedded in a layer of cement, integral with the frame and provided with a heat sink element, and on the other hand, a panel forming a facade of the device integral with the frame and mounted at a distance from the heating element, the element heat sink being partially embedded in the cement layer.
L'objet de la présente invention vise en conséquence à porter remède aux différents problèmes mentionnés précédemment, et à proposer un nouveau type d'appareil de chauffage électrique permettant de fournir une puissance de chauffe équivalente aux appareils traditionnels à l'aide d'éléments chauffants basse température, tout en étant d'un encombrement, et en particulier d'une épaisseur réduite.The object of the present invention therefore aims to remedy the various problems mentioned above, and to propose a new type of electric heating device making it possible to provide a power of heating equivalent to traditional devices using low temperature heating elements, while being compact, and in particular of reduced thickness.
Un autre objet de l'invention est de proposer un appareil de chauffage électrique dans lequel l'isolation électrique des éléments chauffants est améliorée.Another object of the invention is to provide an electric heating device in which the electrical insulation of the heating elements is improved.
Un objet complémentaire de l'invention est de proposer un appareil de chauffage électrique privilégiant le chauffage par rayonnement au détriment du chauffage par convection.An additional object of the invention is to provide an electric heating device favoring the radiant heating at the expense of convection heating.
Les objets assignés à l'invention sont atteints à l'aide d'un appareil de chauffage électrique comprenant un bâti principal dans lequel est monté d'une part au moins un élément chauffant incluant un circuit résistif ledit élément étant associé à une plaque support solidaire du bâti, et pourvue d'un élément dissipateur thermique, et d'autre part au moins une plaque de rayonnement formant une façade de l'appareil solidaire du bâti et montée à distance de l'élément chauffant caractérisé en ce que l'élément chauffant est constitué d'un élément chauffant plat basse température à structure sandwich ladite structure étant isolée électriquement, de préférence sur ses deux faces par des films isolants et collée par une face sur un côté de la plaque support, l'autre côté de la plaque étant pourvue de l'élément dissipateur thermique.The objects assigned to the invention are achieved using an electric heating device comprising a main frame in which is mounted on the one hand at least one heating element including a resistive circuit said element being associated with an integral support plate of the frame, and provided with a heat dissipating element, and on the other hand at least one radiation plate forming a facade of the device integral with the frame and mounted at a distance from the heating element characterized in that the heating element consists of a flat low-temperature heating element with a sandwich structure, said structure being electrically insulated, preferably on its two faces by insulating films and bonded by one face to one side of the support plate, the other side of the plate being provided with the heat sink element.
D'autres particularités et avantages de l'invention apparaîtront et ressortiront plus en détail à partir de la description faite ci-après, en référence aux dessins annexés donnés à titre d'exemples illustratifs et non limitatifs dans lesquels :
- La figure 1 représente selon une vue en perspective un appareil de chauffage électrique conforme à l'invention.

- La figure 3 montre selon une vue en coupe transversale partielle une autre variante de réalisation d'un appareil de chauffage électrique conforme à l'invention.
- Figure 1 shows a perspective view of an electric heater according to the invention.
- FIG. 2 represents, in a partial cross-sectional view, an electric heating device according to the invention and corresponding to the variant shown in FIG. 1.
- Figure 3 shows in a partial cross-sectional view another alternative embodiment of an electric heating device according to the invention.
L'appareil de chauffage électrique conforme à l'invention montré à la figure 1 comprend un bâti principal 1, par exemple métallique, destiné à former l'ossature générale de l'appareil. Dans la version préférentielle de l'invention telle que montrée aux figures 1 à 3, l'appareil de chauffage conforme à l'invention est un appareil à poste fixe destiné par exemple à être fixé sur ou contre une cloison d'habitation. A cet effet le bâti 1 comprend un panneau arrière 2 par lequel l'appareil peut être fixé sur une cloison. Avantageusement, le bâti 1 est de forme sensiblement rectangulaire et est pourvu d'une bordure périphérique définissant deux bordures latérales 3, une bordure supérieure 4 et une bordure inférieure 5.The electric heater according to the invention shown in Figure 1 comprises a
Selon une première caractéristique de l'invention, l'appareil de chauffage est pourvu d'un élément chauffant 10 basse température. Sous le terme "élément chauffant basse température" il convient d'entendre dans le domaine technique considéré, des éléments chauffant incluant des éléments résisitifs dont la température de chauffe n'est pas supérieure à 300 °C et de préférence ne dépasse pas 250 °C, la plage idéale de chauffe étant de l'ordre de 210 à 222 °C. Dans le cadre de l'invention, l'élément chauffant 10 est un élément chauffant plat à structure sandwich du type de celle décrite dans la demande de brevet français n° FR-A-2686761 ou dans la demande de brevet européen correspondante EP-A-0555159 dont les descriptions sont ici considérées comme incorporées dans le texte de la présente demande. L'élément chauffant 10 utilisé de manière préférentielle dans le cadre de la présente invention comporte donc une piste résistive 11 formant par exemple une série de boucles et serpentins, insérée dans une couche de matière thermoplastique telle que du PFA. La structure plane ainsi réalisée est isolée électriquement sur ses deux faces par deux films isolants tel que du polyimide. Dans la variante de réalisation montrée aux figures 1 et 2, l'élément chauffant plat 10 est collé par une face sur une plaque support 15 solidaire du bâti 1. Dans l'exemple représenté aux figures 1 et 2 l'élément chauffant 10 est collé par exemple à l'aide d'une couche de matériau thermoplastique telle que du PFA, sur le côté 15a de la plaque support 15 qui est situé en regard d'un panneau rayonnant 17 formant la façade avant de l'appareil. Le panneau rayonnant 17, s'étend sensiblement au voisinage des bordures 3, 4, 5 de manière à laisser un espace périphérique réduit 18 entre les bordures 3, 4, 5 et le panneau rayonnant 17. L'espace périphérique 18 sert à la création d'un flux naturel de chauffage par convection. Le panneau rayonnant 17 est solidaire du panneau arrière 2 par l'intermédiaire d'une série de pattes de fixation 19, ledit panneau rayonnant 17 étant monté à distance de l'élément chauffant 10. La distance de montage doit être aussi faible que possible de manière à réduire au maximum l'épaisseur totale de l'appareil, mais doit également être suffisante compte tenu du matériau constituant la panneau rayonnant 17, pour que ce dernier ne soit pas susceptible de dépasser les valeurs limites de température de surface imposées par les normes. De manière préférentielle le panneau rayonnant 17 est à base de verre, et la distance entre le panneau 17 et le plan d'extension de l'élément chauffant 10 sera de l'ordre de 12 mm. Le panneau rayonnant peut également être une plaque métallique, de préférence pourvue de perforations.According to a first characteristic of the invention, the heating device is provided with a low
Dans la variante de réalisation montrée aux figures 1 et 2, l'appareil de chauffage comporte un élément dissipateur thermique 20, constitué par exemple d'un panneau profilé définissant une série d'ondulations 21 formant des surfaces d'échange thermique. L'élément dissipateur thermique 20 a pour but d'induire une circulation d'air permettant d'empêcher une montée en température de l'élément chauffant trop importante pouvant conduire à son auto-destruction. Avantageusement, l'élément dissipateur thermique 20 sert à la fois d'entretoise entre le panneau arrière 2 et la plaque support 15 et de moyen de fixation de ladite plaque 15 sur le panneau arrière 2. Dans cette configuration particulière l'élément dissipateur thermique 20 est fixé, par exemple par boulonnage sur le panneau arrière 2 et également par tous moyens appropriés sur la plaque support 15.In the alternative embodiment shown in FIGS. 1 and 2, the heating device comprises a
Avantageusement, l'élément chauffant 10 s'étend sur une surface inférieure à la surface du panneau de rayonnement 17, et représente par exemple le tiers de la surface du panneau rayonnant 17. Dans cette configuration, l'élément chauffant 10 est disposé dans la partie inférieure de la plaque support 15.Advantageously, the
Dans la variante de réalisation montrée à la figure 3, l'élément chauffant 10 est collé sur le côté de la plaque support 15 qui est situé en regard du panneau arrière 2 de l'appareil. Dans cette configuration l'élément dissipateur thermique 20 s'étend entre la plaque support 15 et le panneau de rayonnement 17'. Selon une configuration de construction particulièrement avantageuse, l'élément dissipateur thermique 20 est fixé par tous moyens appropriés sur la plaque support 15 et présente une largeur hors-tout inférieur à la distance entre la plaque support 15 et le panneau rayonnant 17' de manière que les ondulations 21 s'arrêtent à distance de la surface du panneau rayonnant 17'. Selon cette variante de réalisation, la présence de l'élément dissipateur thermique 20 en regard du panneau rayonnant avant 17' permet, par création d'une convexion naturelle sur la partie avant de l'appareil, de réduire la température du panneau rayonnant 17'. Ce dernier est avantageusement constitué d'une plaque métallique, pleine, ou pourvue de perforations.In the alternative embodiment shown in FIG. 3, the
L'appareil de chauffage électrique conforme à l'invention permet en conséquence à l'aide d'éléments chauffants basse température montés en combinaison avec un élément dissipateur thermique 20, de réaliser un appareil de chauffage mixte, par convection et rayonnement, assurant des performances de chauffe équivalentes à des appareils mettant en oeuvre des éléments chauffants haute température. En outre le recours à des éléments chauffants basse température permet de réduire l'épaisseur totale de l'appareil de chauffage sans pour autant réduire les performances de chauffe ni diminuer la durée de vie globale de l'appareil. L'épaisseur hors-tout de l'appareil de chauffage conforme à l'invention est inférieure à 50 mm et de préférence comprise entre 40 et 45 mm. Il convient également de noter que le recours à des éléments chauffants basse température, ainsi que l'agencement global simplifié de l'appareil conduit en définitive à l'obtention d'un appareil de coût réduit. Enfin, l'utilisation d'éléments chauffants basse température permet de diminuer les écarts de dilatation entre les pièces de l'appareil et en conséquence de réduire fortement ou complètement les claquements sonores caractéristiques des dilatations.The electric heating device according to the invention therefore makes it possible, using low temperature heating elements mounted in combination with a
