Abstract

The apparatus (10) has a single piece casing (14) supporting a convective heating body (12) and made of punched sheet metal, and a facade (16) fixed to the casing. A portion of the facade is constituted by modular elements (18) that are fixed with respect to each other and to the casing. One of the elements includes four fixation tabs respectively fixed to fixation tabs of the other element. The tabs of each element are extended along a direction perpendicular to the facade. A heating element e.g. film, heats the facade and covers faces of the modular elements against the casing.

Description

La présente invention concerne un appareil de chauffage électrique.The present invention relates to an electric heater.

Un tel appareil de chauffage électrique, ou radiateur, est classiquement formé d'un capot supportant un corps de chauffe convectif. Le capot est fermé par une façade pour cacher le corps de chauffe convectif. La façade permet également d'empêcher l'accès au corps de chauffe, l'accès à ce corps de chauffe pouvant s'avérer dangereux.Such an electric heater, or radiator, is conventionally formed of a hood supporting a convective heating body. The hood is closed by a facade to hide the convective heater. The facade also prevents access to the heating body, access to the heating body can be dangerous.

Il est connu de réaliser des radiateurs de différentes tailles en fonction de la puissance du corps de chauffe. Notamment, il est connu de réaliser des façades dont l'aire est d'autant plus grande que le corps de chauffe est puissant. L'augmentation de l'aire de la façade vise à augmenter la puissance rayonnée par l'appareil de chauffage. Ceci permet de maintenir constant le rapport entre la puissance émise par l'appareil de chauffage par convexion et l'énergie rayonnée par l'appareil à travers sa façade.It is known to produce radiators of different sizes depending on the power of the heating body. In particular, it is known to make facades whose area is even larger than the heating body is powerful. The increase in the area of the facade aims to increase the power radiated by the heater. This makes it possible to maintain constant the ratio between the power emitted by the convection heater and the energy radiated by the appliance through its facade.

L'augmentation de l'aire de la façade en fonction de la puissance du corps de chauffe présente cependant l'inconvénient qu'il est nécessaire de concevoir autant de façades que d'appareils de chauffage électrique de puissances différentes ou de modèles différents.However, the increase in the area of the facade as a function of the power of the heating body has the disadvantage that it is necessary to design as many facades as electric heaters of different powers or different models.

En effet, la conception de la façade est critique pour les fabricants de radiateurs. La façade est effectivement l'élément prépondérant de l'esthétique d'un radiateur. L'esthétique du radiateur est l'un des principaux critères de choix des clients. La conception et la fabrication de différentes tailles de façades sont donc très onéreuses.Indeed, the design of the facade is critical for radiator manufacturers. The facade is indeed the dominant element of the aesthetics of a radiator. The aesthetics of the radiator is one of the main criteria of choice of the customers. The design and manufacture of different sizes of facades are therefore very expensive.

Le but de la présente invention est de fournir un radiateur permettant de résoudre ces inconvénients.The object of the present invention is to provide a radiator to solve these disadvantages.

Cependant, il est connu de FR-A-2 716 255 de réaliser le radiateur entier au moyen d'éléments modulaires. Chacun de ses éléments présente la forme d'une brique et comprend une fente en son sein. Ainsi, lorsque les éléments modulaires sont placés les uns à côté des autres, les fentes de ces éléments sont alignés et forment ainsi un logement pour recevoir le corps de chauffe. Dans ce cas, le radiateur est dépourvu d'un capot distinct.However, it is known to FR-A-2,716,255 to achieve the entire radiator by means of modular elements. Each of its elements has the shape of a brick and includes a slot in it. Thus, when the modular elements are placed next to each other, the slots of these elements are aligned and thus form a housing for receiving the heating body. In this case, the radiator does not have a separate hood.

Ce dispositif présente cependant l'inconvénient d'être de conception complexe, la réalisation des éléments modulaires étant coûteuse. En outre, le montage du corps de chauffe convectif dans la fente s'avère complexe, ce qui nuit à la rapidité de fabrication du radiateur.This device however has the disadvantage of being of complex design, the realization of the modular elements being expensive. In addition, the mounting of the convective heater in the slot is complex, which affects the speed of manufacture of the radiator.

La présente invention propose un appareil de chauffage électrique comprenant un corps de chauffe convectif, un capot, supportant le corps de chauffe et une façade fixée au capot, au moins une portion de la façade étant constituée d'éléments modulaires.The present invention provides an electric heater comprising a convective heater body, a hood, supporting the heater and a facade attached to the hood, at least a portion of the facade being made of modular elements.

Selon l'invention, un appareil de chauffage électrique comprend un corps de chauffe convectif, un capot supportant le corps de chauffe et une façade fixée au capot. Au moins une portion de la façade est constituée d'éléments modulaires.According to the invention, an electric heater comprises a convective heater, a hood supporting the heater and a front attached to the hood. At least a portion of the facade is made of modular elements.

Ainsi, la réalisation d'appareils de chauffage électrique, ou radiateurs, de différentes puissances est facilitée et moins onéreuse. En effet, des radiateurs de différentes puissances sont généralement de tailles différentes. Il est notamment connu de réaliser différents radiateurs de la même hauteur (ou de la même longueur) mais de longueurs (respectivement hauteurs) différentes en fonction de la puissance. Dans ce cas, pour réaliser les façades de différentes tailles, on réalise au moins une portion de cette façade à l'aide d'éléments modulaires. Ainsi, plus la façade est grande et plus cette portion de la façade comprend d'éléments modulaires.Thus, the realization of electric heaters, or radiators, of different powers is facilitated and less expensive. Indeed, radiators of different powers are generally of different sizes. It is in particular known to produce different radiators of the same height (or the same length) but lengths (respectively heights) different depending on the power. In this case, to realize the facades of different sizes, at least a portion of this facade is made using modular elements. Thus, the larger the facade, the more this portion of the facade comprises modular elements.

Ce mode de réalisation de la façade est particulièrement avantageux du point de vu du coût de fabrication. En effet, au lieu de développer différentes façades de tailles différentes, il suffit de développer des éléments modulaires. Ces éléments modulaires peuvent être utilisés dans la fabrication des différentes tailles de façades.This embodiment of the facade is particularly advantageous from the point of view of the manufacturing cost. Indeed, instead of developing different facades of different sizes, it is sufficient to develop modular elements. These modular elements can be used in the manufacture of different sizes of facades.

Lorsque les éléments modulaires sont identiques, le coût de fabrication est encore réduit.When the modular elements are identical, the manufacturing cost is further reduced.

La seule réalisation de la façade au moyen d'éléments modulaires présente en outre un coût moindre que la réalisation commune du capot et de la façade au moyen d'éléments modulaires comme cela est décrit dans la demande FR-A-2 716 255 . Les éléments modulaires selon l'invention sont de géométrie plus simple puisqu'ils n'ont pas à former un logement pour la réception du corps de chauffe. Leur coût de fabrication est donc moins élevé que celui des éléments modulaires de la demande FR-A-2 716 255 .The only embodiment of the facade by means of modular elements also has a lower cost than the common realization of the cover and the facade by means of modular elements as described in the application FR-A-2,716,255 . The modular elements according to the invention are of simpler geometry since they do not have to form a housing for the reception of the heating body. Their manufacturing cost is therefore lower than that of the modular elements of demand FR-A-2,716,255 .

En outre, lorsque le capot est réalisé en tôle emboutie, l'appareil de chauffage électrique ainsi obtenu est nettement moins lourd que l'appareil de chauffage électrique décrit dans la demande FR-A-2 716 255 . Un gain de poids par rapport à cet appareil de chauffage électrique peut également être obtenu quand le capot est réalisé de manière monobloc et non par des éléments modulaires formant également la façade.In addition, when the hood is made of stamped sheet metal, the electric heater thus obtained is significantly lighter than the electric heater described in the application. FR-A-2,716,255 . A weight saving with respect to this electric heater can also be obtained when the hood is made integrally and not by modular elements also forming the facade.

La façade peut être formée exclusivement d'éléments modulaires. La façade peut également comprendre uniquement des éléments modulaires et des joues latérales. Les joues latérales permettent alors une fixation esthétique de la façade sur le capot.The facade can be formed exclusively of modular elements. The facade may also include only modular elements and side cheeks. The side cheeks then allow an aesthetic fixation of the facade on the hood.

Ces joues latérales permettent de fermer l'espace latérale entre la façade et le capot. Elles ont également une fonction esthétique. En outre, ces joues permettent de fixer la façade au niveau d'une ou de plusieurs surfaces latérales du capot. Ainsi, les moyens de fixation de la façade sur le capot ne sont pas visibles sur la façade.These side cheeks make it possible to close the lateral space between the front and the hood. They also have an aesthetic function. In addition, these cheeks allow to fix the facade at one or more side surfaces of the hood. Thus, the fastening means of the facade on the hood are not visible on the facade.

Les surfaces latérales du capot, sur lesquels peuvent être fixées les joues latérales, peuvent par exemple être formées par des bords rabattus. Ce mode de réalisation est facile à mettre en oeuvre, notamment quand le capot est réalisé en tôle emboutie.The side surfaces of the hood, on which can be attached the side cheeks, may for example be formed by folded edges. This embodiment is easy to implement, especially when the cover is made of pressed sheet metal.

Avantageusement, les éléments modulaires peuvent être fixés au capot. Dans ce cas, les éléments modulaires peuvent ne pas être fixés entre eux. Cette fixation directe des éléments modulaires sur le capot permet de réaliser rapidement la façade, en fixant autant d'éléments modulaires que nécessaires sur le capot. En outre, cette fixation directe des éléments modulaires sur le capot est particulièrement solide.Advantageously, the modular elements can be fixed to the hood. In this case, the modular elements may not be fixed together. This direct attachment of the modular elements on the cover makes it possible to quickly realize the facade, by fixing as many modular elements as necessary on the cover. In addition, this direct attachment of the modular elements on the hood is particularly solid.

Cependant, alternativement ou de manière complémentaire, les éléments modulaires peuvent être fixés entre eux. Ceci permet notamment de réaliser la façade séparément du capot. La façade est ensuite rapportée et fixée au capot.However, alternatively or in a complementary manner, the modular elements can be fixed together. This allows in particular to realize the facade separately hood. The facade is then attached and attached to the hood.

En outre, lorsque les éléments modulaires sont fixés entre eux, la façade peut être fixée au capot en moins de points. Le démontage de la façade, en cas de maintenance, s'en trouve facilité.In addition, when the modular elements are fixed together, the front can be fixed to the hood in less points. Disassembly of the facade, in case of maintenance, is facilitated.

La fixation des éléments modulaires entre eux peut être réalisée en fixant tous les éléments modulaires à un même corps de fixation, par exemple une barre. Il est à noter que le corps de fixation peut ne pas être fixé au capot. Il est ainsi possible de réaliser la façade d'une part et le capot d'autre part, séparément. En d'autres termes, la fabrication de la façade et du capot peut ainsi être réalisée parallèlement. Il n'est pas nécessaire de réaliser le capot avant de réaliser la façade. Cela présente un gain de temps de fabrication de l'appareil de chauffage.Fixing the modular elements together can be achieved by fixing all the modular elements to the same fastening body, for example a bar. Note that the mounting body may not be attached to the hood. It is thus possible to realize the facade on the one hand and the hood on the other hand, separately. In other words, the manufacture of the front and the hood can thus be carried out in parallel. It is not necessary to make the cover before making the facade. This saves manufacturing time of the heater.

Tel que représenté sur la figure 1, un appareil de chauffage électrique 10 comporte un corps de chauffe convectif 12, un capot 14, supportant le corps de chauffe 12 et une façade 16, fixée au capot 14.As shown on the figure 1 an electric heating apparatus 10 comprises a convective heating body 12, a hood 14, supporting the heating body 12 and a front panel 16, fixed to the hood 14.

Sur la figure 1, la façade 16 est entièrement constituée d'éléments modulaires 18. Cependant, on peut envisager que seule une portion de la façade soit réalisée au moyen d'éléments modulaires. Notamment, la façade peut comporter une ou plusieurs portions formées au moyen d'éléments modulaires, ces portions de façade pouvant être reliées entre elles pour former la façade par des éléments qui ne sont pas modulaires. Seule une certaine surface ou certaines surfaces de la façade peu(ven)t ainsi être réalisée(s) au moyen d'éléments modulaires.On the figure 1 , the facade 16 is entirely made of modular elements 18. However, it can be envisaged that only a portion of the facade is made by means of modular elements. In particular, the facade may comprise one or more portions formed by means of modular elements, these facade portions may be interconnected to form the facade by elements that are not modular. Only a certain surface or surfaces of the facade can thus be achieved by means of modular elements.

Le corps de chauffe 12 comprend généralement un élément chauffant, par exemple une résistance électrique, et un corps de chauffe pour éviter un contact direct de l'air à chauffer avec l'élément chauffant. Ceci permet de réduire l'assèchement de l'air chauffé. Le corps de chauffe peut par exemple être en fonte ou en alliage d'aluminium pour présenter une certaine inertie thermique permettant de continuer de chauffer l'air au voisinage de l'appareil de chauffe électrique même lorsque l'élément chauffant ne chauffe plus.The heating body 12 generally comprises a heating element, for example an electrical resistance, and a heating element to prevent direct contact of the air to be heated with the heating element. This reduces the drying of the heated air. The heating body may for example be cast iron or aluminum alloy to have a certain thermal inertia for continuing to heat the air in the vicinity of the electric heating device even when the heating element no longer heats.

Le capot 14 peut être réalisé en tôle pour en limiter le coût. La réalisation du capot en tôle ne nuit pas, en général, à l'esthétique de l'appareil de chauffage électrique. En effet, le capot est destiné à être caché par la façade.The cover 14 may be made of sheet metal to limit the cost. The realization of the sheet metal hood does not, in general, harm the aesthetics of the electric heater. Indeed, the hood is intended to be hidden by the facade.

De préférence, le capot 14 est monobloc. Il est ainsi plus aisé à fabriquer. Il peut être par exemple fabriqué par emboutissage. Le capot est plus aisé à fabriquer qu'un capot constitué par l'assemblage de parois à un fond, par exemple par soudage.Preferably, the cover 14 is in one piece. It is thus easier to manufacture. It can be for example manufactured by stamping. The hood is easier to manufacture than a hood constituted by the assembly of walls to a bottom, for example by welding.

Le capot 14 présente en l'espèce quatre bords rabattus 14a, 14b, 14c, 14d définissant un volume intérieur dans lequel est reçu le corps de chauffe 12. En d'autres termes, le capot a une forme de parallélépipède dont une face est ouverte.The cover 14 has in this case four folded edges 14a, 14b, 14c, 14d defining an interior volume in which the heating body 12 is received. In other words, the cover has a parallelepiped shape of which one face is open .

Les bords rabattus sont réalisés de manière monobloc avec le capot. Cela est facilement réalisable par emboutissage d'une tôle. Ce mode de réalisation du capot s'avère plus rapide que celui consistant à réaliser le capot sous forme d'une plaque sur laquelle les bords rabattus sont rapportés.The folded edges are made integrally with the hood. This is easily achieved by stamping a sheet. This embodiment of the hood is faster than that of making the cover in the form of a plate on which the folded edges are reported.

Le capot peut comporter des moyens de fixation de l'appareil de chauffage électrique à un portant tel qu'un mur ou à un support fixé au portant.The cover may comprise means for fixing the electric heater to a bearing such as a wall or a support attached to the bearing.

D'autres éléments que le corps de chauffe peuvent également être fixés au capot. Notamment, un élément d'interface homme machine ou une sonde de température peuvent être fixés au capot.Other elements than the heater may also be attached to the hood. In particular, a human machine interface element or a temperature probe can be attached to the hood.

La façade 16 est réalisée au moyen d'éléments modulaires 18. En l'espèce, les éléments modulaires 18 ont une forme sensiblement rectangulaire. Les éléments modulaires 18 peuvent avoir une forme de latte. Ils présentent donc deux grands côtés parallèles 18b, 18c et deux petits côtés parallèles 18a, 18d, perpendiculaires aux grands côtés parallèles 18b, 18c. Bien entendu, cette forme des éléments modulaires n'est nullement limitative et d'autres formes des éléments modulaires 18 sont envisageables. Les éléments modulaires pourraient ainsi avoir une forme ondulée ou encore une forme d'éclair, à titre d'exemples non limitatifs.The facade 16 is made by means of modular elements 18. In this case, the modular elements 18 have a substantially rectangular shape. The elements modular 18 may have a batten shape. They therefore have two large parallel sides 18b, 18c and two small parallel sides 18a, 18d, perpendicular to the large parallel sides 18b, 18c. Of course, this form of the modular elements is in no way limiting and other forms of the modular elements 18 are conceivable. The modular elements could thus have a wavy shape or a form of lightning, as non-limiting examples.

Les éléments modulaires sont avantageusement réalisés par moulage ou par extrusion. Ainsi, notamment, lorsque les éléments modulaires sont réalisés par moulage, un seul moule peut suffire pour réaliser toutes les tailles de façade.The modular elements are advantageously made by molding or extrusion. Thus, in particular, when the modular elements are made by molding, a single mold can be sufficient to achieve all facade sizes.

La façade peut être recouverte, sur son côté en regard du capot 14, par des éléments permettant de chauffer cette façade. Il peut notamment s'agir d'un ou de plusieurs films chauffants. La façade, chauffée, permet un chauffage radiatif au voisinage de la façade.The facade may be covered, on its side facing the cover 14, by elements for heating the facade. It can in particular be one or more heating films. The facade, heated, allows a radiative heating in the vicinity of the facade.

Selon la figure 1, la façade 16 d'une part et le capot 14 forment chacun une demi coquille. Les demi coquilles sont assemblées entre elles pour obtenir l'appareil électrique. Les demi coquilles forment chacune un ensemble monobloc, les deux ensembles étant assemblés entre eux. Les demi coquilles assemblées forment un logement intérieur pour recevoir le corps de chauffe.According to figure 1 , the facade 16 on the one hand and the cover 14 each form a half shell. The half shells are assembled together to obtain the electrical apparatus. The half-shells each form a one-piece assembly, the two assemblies being assembled together. The assembled half-shells form an inner housing for receiving the heating body.

Selon une variante non représentée, une plaque, par exemple métallique, peut être interposée entre la façade 16 et le corps de chauffe 12, pour empêcher l'accès au corps de chauffe 12 depuis un espace entre des éléments modulaires 18 de la façade 16. Ceci permet de cloisonner l'intérieur du capot. Ceci permet d'éviter à un utilisateur d'avoir accès au corps de chauffe. La sécurité d'utilisation est augmentée. La plaque peut être solidaire des éléments modulaires 18. La plaque est alors fixée en même temps que les éléments modulaires. Les éléments modulaires 18 peuvent être fixés à la plaque.According to a variant not shown, a plate, for example metal, can be interposed between the facade 16 and the heating body 12, to prevent access to the heating body 12 from a space between modular elements 18 of the facade 16. This allows to partition the inside of the hood. This prevents a user from having access to the heating body. The safety of use is increased. The plate can be secured to the modular elements 18. The plate is then fixed at the same time as the modular elements. Modular elements 18 may be attached to the plate.

Un premier exemple de façade est décrit dans la suite en regard de la figure 2.A first example of a facade is described below with regard to the figure 2 .

Sur cette figure 2, la façade 16 est représentée vue de derrière. Comme représenté sur cette figure, chaque élément modulaire 18 présente des corps de fixation pour la fixation des éléments modulaires 18 les uns aux autres. Les corps de fixation peuvent être amovibles pour pouvoir démonter facilement les éléments. Les corps de fixation peuvent être fixés entre eux par exemple par des clips qui sont des pinces formant ressort.On this figure 2 , the facade 16 is shown from behind. As shown in this figure, each modular element 18 has fixing bodies for fixing the modular elements 18 to each other. The fasteners can be removable to easily dismount the elements. The fastening bodies can be fastened to each other for example by clips which are spring clips.

Les corps de fixation permettent de positionner les éléments modulaires correctement les uns par rapport aux autres avant de les fixer sur le capot. Ceci permet d'obtenir une façade monobloc qui peut être montée d'un seul tenant au capot.The fasteners allow the modular elements to be correctly positioned relative to one another before attaching them to the hood. This provides a monobloc facade that can be mounted in one piece to the hood.

Selon la figure 2, les corps de fixation sont monoblocs avec les éléments modulaires et sont tels que des pattes de fixation. Les éléments de la figure 2 comportent chacun quatre pattes de fixation 20, 21, 22, 23. Deux pattes supérieures 20, 21 sont situées sur une portion supérieure de l'élément modulaire 18. Deux pattes inférieures 22, 23 sont situées sur une portion inférieure de l'élément modulaire 18.According to figure 2 , the fastening bodies are monoblock with the modular elements and are such that fixing lugs. The elements of the figure 2 each comprise four fastening tabs 20, 21, 22, 23. Two upper tabs 20, 21 are located on an upper portion of the modular element 18. Two lower tabs 22, 23 are located on a lower portion of the modular element 18.

Une première patte supérieure 20 est située à proximité de l'un 18b des grands côtés de l'élément modulaire tandis que la seconde patte supérieure 21 est située, en regard de la première patte supérieure 20, à proximité de l'autre grand côté 18d de l'élément modulaire 18.A first upper leg 20 is located near one 18b of the long sides of the modular element while the second upper leg 21 is located, facing the first upper leg 20, near the other large side 18d of the modular element 18.

De même, une première patte inférieure 22 est située à proximité de l'un 18b des grands côtés de l'élément modulaire tandis que la seconde patte inférieure 23 est située, en regard de la première patte inférieure 22, à proximité de l'autre grand côté 18d de l'élément modulaire 18.Similarly, a first lower leg 22 is located near one 18b of the long sides of the modular element while the second lower leg 23 is located, opposite the first lower leg 22, close to the other large side 18d of the modular element 18.

Ainsi, lorsque deux éléments modulaires 18 sont disposés l'un à côté de l'autre, les premières pattes supérieure 20 et inférieure 22 de l'un sont en regard des secondes pattes supérieure 21 et inférieure 23 de l'autre, respectivement.Thus, when two modular elements 18 are arranged next to each other, the first upper tabs 20 and lower 22 of one are opposite the second upper tabs 21 and lower 23 of the other, respectively.

Les pattes sont décrites dans la suite en regard de la figure 3. La figure 3 ne montre que des pattes inférieures. Cependant, les pattes supérieures peuvent être identiques aux pattes inférieures.The legs are described below next to the figure 3 . The figure 3 only shows lower legs. However, the upper legs may be identical to the lower legs.

Chaque patte 20, 21, 22, 23 a la forme d'un « T » faisant saillie depuis la surface de l'élément modulaire 18. Ces pattes présentent deux trous 24, 25, formés en l'espèce aux extrémités de la barre horizontale 26 du « T ». Les trous 24, 25 sont traversants.Each tab 20, 21, 22, 23 has the shape of a "T" projecting from the surface of the modular element 18. These tabs have two holes 24, 25, formed in this case at the ends of the horizontal bar 26 of the "T". The holes 24, 25 are through.

La fixation des éléments modulaires peut ainsi être réalisée en plaçant une patte en face d'une autre de manière que les trous traversants 24, 25 soient en regard deux à deux. Les pattes de chaque couple de pattes sont alors fixées au moyen de deux boulons 26.Fixing the modular elements can thus be achieved by placing one tab opposite another so that the through holes 24, 25 are facing two by two. The legs of each pair of legs are then fixed by means of two bolts 26.

La fixation des éléments modulaires peut également être réalisée par vissage, clipsage ou tout autre système de fixation.Fixing the modular elements can also be achieved by screwing, clipping or any other fastening system.

Avantageusement, le positionnement des éléments modulaires entre eux peut être réalisé ou tout du moins guidé, avant fixation des éléments modulaires entre eux, au moyen de systèmes de type pion de centrage, de gorges ou d'épaulements.Advantageously, the positioning of the modular elements together can be achieved or at least guided, before fixing the modular elements together, by means of centering pin type systems, grooves or shoulders.

La figure 4 représente un autre exemple de façade 116 adaptée à l'appareil de chauffage électrique 10.The figure 4 is another example of facade 116 adapted to the electric heater 10.

La façade 116 est constituée d'éléments modulaires 118. Les éléments modulaires 118 sont fixés les uns aux autres par des corps de fixation. Les corps de fixation sont par exemple sous forme de deux barres de fixation 130, 132. Pour ce faire, chaque élément modulaire 118 est fixé à chacune des deux barres de fixation 130, 132, par exemple au moyen de vis. Pour faciliter le montage des éléments modulaires sur les barres de fixation, les éléments modulaires peuvent comporter deux pions de centrage 134, 136 adaptée à pénétrer dans des trous correspondants formés dans les barres de fixation. Les éléments modulaires peuvent ensuite être fixés aux barres au moyen de vis. Les vis peuvent notamment être vissées dans les pions de centrage des éléments modulaires.The facade 116 is made of modular elements 118. The modular elements 118 are fixed to each other by fixing bodies. The fixing bodies are for example in the form of two fixing bars 130, 132. To do this, each modular element 118 is attached to each of the two fixing bars 130, 132, for example by means of screws. To facilitate the mounting of the modular elements on the fixing bars, the modular elements may comprise two centering pins 134, 136 adapted to penetrate into corresponding holes formed in the fixing bars. The modular elements can then be attached to the bars by means of screws. The screws can in particular be screwed into the centering pins of the modular elements.

Bien entendu, d'autres moyens de fixation tel que le clipsage ou la soudure, ainsi que tout moyen de fixation démontable peut être mis en oeuvre pour fixer les éléments modulaires sur les barres de fixation. En outre, il peut être prévu de fixer chaque élément modulaire à chaque barre de fixation au moyens de plusieurs vis afin d'assurer une meilleure rigidité de la façade et un meilleur alignement des éléments modulaires formant la façade.Of course, other fastening means such as clipping or welding, as well as any removable fastening means can be implemented to fix the modular elements on the fastening bars. In addition, it may be provided to fix each modular element to each fixing bar by means of several screws to ensure a better rigidity of the facade and a better alignment of the modular elements forming the facade.

Les barres de fixation permettent de positionner les éléments modulaires correctement les uns par rapport aux autres avant de les fixer sur le capot. Ceci permet d'obtenir une façade monobloc qui peut être montée d'un seul tenant au capot. Ces barres de fixation peuvent alors, selon un premier exemple, être fixées directement sur le capot de l'appareil de chauffage.The mounting bars are used to position the modular elements correctly relative to each other before attaching them to the hood. This provides a monobloc facade that can be mounted in one piece to the hood. These fixing bars can then, according to a first example, be fixed directly to the hood of the heater.

Bien entendu, le nombre de barres de l'exemple - deux - n'est nullement limitatif. Les mêmes effets et avantages peuvent être obtenus avec une seule barre ou avec plus de deux barres de fixation. Cependant, un nombre important de barres de fixation permet d'augmenter la rigidité de la façade formée par la fixation des éléments modulaires sur les barres. Ainsi, plus la façade à réaliser est grande - c'est-à-dire plus le nombre d'éléments modulaires à fixer est grand - plus le nombre de barres de fixation sera grand.Of course, the number of bars of the example - two - is in no way limiting. The same effects and benefits can be achieved with a single bar or with more than two mounting bars. However, a large number of fixing bars makes it possible to increase the rigidity of the facade formed by the fixing of the modular elements on the bars. Thus, the larger the facade to achieve is - that is to say the more the number of modular elements to fix is large - the more the number of fixing bars will be large.

Bien entendu, d'autres moyens de fixation des éléments modulaires sur la ou les barres de fixation sont envisageables. En particulier, les éléments modulaires peuvent être fixés sur la ou les barres de fixation par clipsage. Il est aussi envisageable que les corps de fixation soient la plaque décrite ci-dessus empêchant l'accès à l'intérieur de l'appareil de chauffage.Of course, other means of fixing the modular elements on the fixing bar or bars are possible. In particular, the modular elements can be fixed on the fixing bar or bars by clipping. It is also conceivable that the fixing bodies are the plate described above preventing access to the interior of the heater.

La figure 5 représente schématiquement une variante de la façade 116 de la figure 4. Dans le cas de la figure 5, en effet, la façade 116 comprend, outre les éléments modulaires 118 fixés entre eux au moyen d'au moins un corps de fixation tel qu'une barre de fixation 130, 132, des joues 140, 142. Ces joues 140, 142 complètent donc la façade 116. Les joues présentent une surface esthétique sur le côté, selon une direction sensiblement perpendiculaire à la façade. Les joues permettent ainsi d'empêcher l'accès à l'intérieur de l'appareil électrique de chauffage. Les joues peuvent également présenter, comme cela est représenté sur la figure 5, une surface esthétique formant une portion de la façade. Ainsi, en l'espèce, les joues 140, 142 présentent une section en forme d'équerre. En d'autres termes, ces joues s'étendent d'une part dans le plan de la figure 5 - c'est-à-dire le plan de la façade 116 - et, d'autre part, perpendiculairement au plan de la figure 5.The figure 5 schematically represents a variant of the facade 116 of the figure 4 . In the case of figure 5 , in fact, the facade 116 comprises, besides the modular elements 118 fixed together by means of at least one fastening body such as a fixing bar 130, 132, cheeks 140, 142. These cheeks 140, 142 complete therefore the facade 116. The cheeks have an aesthetic surface on the side, in a direction substantially perpendicular to the facade. The cheeks thus prevent access to the interior of the electric heater. The cheeks may also present, as shown on the figure 5 , a surface aesthetic forming a portion of the facade. Thus, in this case, the cheeks 140, 142 have a square section. In other words, these cheeks extend on the one hand in the plane of the figure 5 - that is to say the plane of the facade 116 - and, secondly, perpendicular to the plane of the figure 5 .

En l'espèce, les joues 140, 142 peuvent être fixées aux barres de fixation 130, 132, grâce à des moyens de fixations identiques à ceux mis en oeuvre pour la fixation des éléments modulaires entre eux. Cependant, de manière plus générale, ces joues peuvent être fixées aux barres de fixation par tout moyens de fixation compatibles à la fixation des éléments modulaires entre eux.In this case, the cheeks 140, 142 can be fixed to the fixing bars 130, 132, by means of fasteners identical to those used for fixing the modular elements together. However, more generally, these cheeks may be fixed to the fixing bars by any fixing means compatible with the fixing of the modular elements together.

Les joues 140, 142 peuvent également être fixées au capot 14 de l'appareil de chauffage électrique. Les joues 140, 142 permettent ainsi la fixation de la façade 116 sur le capot 14 de l'appareil de chauffage électrique 10.The cheeks 140, 142 may also be attached to the hood 14 of the electric heater. The cheeks 140, 142 thus allow the fixing of the facade 116 on the cover 14 of the electric heater 10.

La fixation des joues 140, 142 sur le capot 14 est avantageusement réalisée sur un ou plusieurs des bords rabattus 14a-14d du capot. Ainsi, les moyens de fixation des joues sur le capot ne sont pas visibles sur la façade 116 et ne nuisent donc pas à l'esthétique de l'appareil électrique de chauffage.The fixing of the cheeks 140, 142 on the cover 14 is advantageously carried out on one or more of the folded edges 14a-14d of the cover. Thus, the fastening means of the cheeks on the hood are not visible on the facade 116 and therefore do not affect the aesthetics of the electric heater.

Les joues 140, 142 s'adaptent aussi à l'appareil de la figure 2. Les joues présentent les mêmes formes et avantages que ceux décrits en liaison avec la figure 5. Les joues peuvent comporter les mêmes corps de fixation que ceux présentés sur la figure 3, une patte de fixation 21, 23 étant prévue à chaque extrémité des joues. En fait, les joues peuvent présenter tous corps de fixation compatibles avec la fixation des éléments modulaires à la barre.The cheeks 140, 142 also adapt to the apparatus of the figure 2 . The cheeks have the same shapes and benefits as those described in connection with the figure 5 . The cheeks may have the same fixation bodies as those shown on the figure 3 , a fixing lug 21, 23 being provided at each end of the cheeks. In fact, the cheeks may have any fasteners compatible with the fixing of the modular elements to the bar.

La fixation des joues sur le capot peut également être réalisée sur un ou plusieurs rebords des bords rabattus.The fixing of the cheeks on the cover can also be performed on one or more edges of the folded edges.

Les figures 6-9 représentent des exemples d'éléments modulaires pouvant être mis en oeuvre pour réaliser la façade de l'appareil de chauffage électrique 10.The Figures 6-9 are examples of modular elements that can be implemented to achieve the front of the electric heater 10.

L'élément modulaire 118 de la figure 6 présente deux appendices 134, 136 pour permettre la fixation de l'élément modulaire 118 sur les barres de fixation 130, 132. Les appendices peuvent notamment former des pions de centrage pour faciliter la mise en place relative de l'élément modulaire et des barres de fixation. En outre, les appendices 134, 136 peuvent comporter un trou taraudé pour permettre la fixation par vissage de l'élément modulaire sur les barres de fixation.The modular element 118 of the figure 6 has two appendages 134, 136 to allow the attachment of the modular element 118 on the fastening bars 130, 132. The appendices may in particular form centering pins to facilitate the relative establishment of the modular element and the bars of fixation. In addition, the appendices 134, 136 may comprise a tapped hole to allow the screw fixing of the modular element on the fastening bars.

L'élément modulaire 18 dont un seul côté est visible sur la figure 7 comprend des pattes de fixation 21, 23 pour permettre la fixation de deux éléments modulaires 18 entre eux, comme expliqué plus haut.The modular element 18 of which only one side is visible on the figure 7 comprises fastening lugs 21, 23 to allow the attachment of two modular elements 18 between them, as explained above.

La figure 8 illustre un élément modulaire 218 présentant des ailettes 220 adaptées à diriger le flux d'air chauffé au moyen du corps chauffant convectif 12. Ces ailettes permettent notamment d'éloigner ce flux d'air du mur, pour éviter un encrassement rapide du mur à proximité de l'appareil électrique de chauffage. Les ailettes assurent également que l'espace intérieur de l'appareil de chauffage électrique n'est pas accessible depuis l'extérieur de celui-ci. En outre, les ailettes peuvent comporter des moyens adaptés à la fixation de l'élément modulaire sur le capot. Les ailettes peuvent être réalisées de manière monobloc avec l'élément modulaire. Cependant, pour faciliter la fabrication des éléments modulaires, ces ailettes peuvent être réalisées séparément de l'élément modulaire et être rapportées sur l'élément modulaire postérieurement.The figure 8 illustrates a modular element 218 having fins 220 adapted to direct the flow of heated air by means of the convective heater 12. fins allow in particular to move this air flow from the wall, to prevent rapid clogging of the wall near the electrical heater. The fins also ensure that the interior space of the electric heater is not accessible from outside the heater. In addition, the fins may comprise means adapted for fixing the modular element on the hood. The fins can be made integrally with the modular element. However, to facilitate the manufacture of modular elements, these fins can be made separately from the modular element and be reported on the modular element posteriorly.

Bien entendu, la présence de ces ailettes 222 est indépendante du mode de fixation des éléments modulaires 218 qui peut être entre eux, ou sur une ou plusieurs barres de fixation. En d'autres termes, les éléments modulaires 18, 118 pourraient également être munis de telles ailettes 220, 222. C'est-à-dire que les différents modes de réalisation décrits des éléments modulaires peuvent être combinés .Ces rebords s'étendent sensiblement parallèlement à la surface formant le fond du capot. En d'autres termes, ces rebords s'étendent sensiblement perpendiculairement au bord rabattu dont ils sont issus. Les bords rabattus s'étendent de préférence vers l'extérieur du capot. En d'autres termes, chaque rebord s'étend dans le demi-plan délimité par le bord rabattu dont il est issu et qui ne comprend pas les autres bords rabattus du capot. Les rebords sont ainsi aisément accessibles depuis le côté de l'appareil de chauffage opposé à la façade. La fixation de la façade sur ces rebords permet ainsi un montage et un démontage aisés de la façade.Of course, the presence of these fins 222 is independent of the fixing mode of the modular elements 218 which can be between them, or on one or more fixing bars. In other words, the modular elements 18, 118 could also be provided with such fins 220, 222. That is to say that the various embodiments described modular elements can be combined. These edges extend substantially parallel to the surface forming the bottom of the hood. In other words, these flanges extend substantially perpendicular to the folded edge from which they are derived. The folded edges preferably extend towards the outside of the hood. In other words, each flange extends in the half-plane defined by the folded edge from which it is derived and which does not include the other folded edges of the hood. The edges are thus easily accessible from the side of the heater opposite the facade. Fixing the facade on these edges allows easy assembly and disassembly of the facade.

Enfin, les figures 9a, 9b illustrent un exemple d'élément modulaire 318 présentant des nervures 320, 322 de renfort de l'élément modulaire 318. Ces nervures permettent d'éviter des déformations de l'élément modulaire 318. Là encore, les éléments modulaires des figures précédentes peuvent présenter de telles nervures de renfort, combinées, le cas échéant avec les ailettes de direction du flux de l'élément modulaire 218 de la figure 8.Finally, Figures 9a, 9b illustrate an example of modular element 318 having ribs 320, 322 for reinforcing the modular element 318. These ribs prevent deformation of the modular element 318. Again, the modular elements of the preceding figures may have such reinforcing ribs, combined, if necessary with the flow direction vanes of the modular element 218 of the figure 8 .

La façade de l'une ou l'autre des figures est une façade ayant l'aspect d'un appareil de chauffage dans lequel un liquide chauffé circule. Ce type d'appareil de chauffage est appelé usuellement radiateur électrique à fluide. Les fentes ou interstices qui demeurent entre les éléments modulaires dans l'appareil décrit ci-dessus reproduisent l'aspect esthétique des appareils de chauffage liquide.The front of one or the other of the figures is a facade having the appearance of a heater in which a heated liquid circulates. This type of heater is usually referred to as an electric fluid heater. The slots or interstices that remain between the modular elements in the apparatus described above reproduce the aesthetic appearance of the liquid heaters.

Les éléments modulaires décrits ci-dessus peuvent être plans ou être galbés.The modular elements described above can be planar or curved.
