Description

Appareil électrique de chauffage Electric heating apparatus
Ce descriptif concerne un appareil électrique permettant le chauffage de lieux extérieurs tels que les terrasses, balcons etc. Ce radiateur propose une alternative aux chauffages extérieurs fonctionnant au gaz propane/butane.This description relates to an electrical appliance for heating outdoor places such as terraces, balconies, etc. This radiator offers an alternative to outdoor heaters running on propane / butane gas.
Le choix de l'énergie électrique pour ce type d'appareil permet un gain considérable au niveau poids, encombrement et entretien.The choice of electrical energy for this type of device allows a considerable gain in weight, bulk and maintenance.
Le déplacement et le stockage de l'appareil se voient donc sensiblement simplifiés et sécurisés en l'absence de risque de fuite de gaz.The movement and storage of the device are therefore significantly simplified and secure in the absence of risk of gas leakage.
Le design évolue aussi vers des formes plus légères et aériennes ; il rompt définitivement avec les appareils qui possèdent tous une forme de révolution : bonbonne de gaz en partie inférieure et soucoupe en partie supérieure. Cet appareil se branche directement sur le secteur via une simple prise de courant. Ceci permet de supprimer la désagréable panne de gaz et d'épargner à l'utilisateur de devoir changer régulièrement la lourde bonbonne.Design is also evolving towards lighter, more airy forms; it breaks definitively with devices that all have a form of revolution: gas cylinder in the lower part and saucer in the upper part. This unit connects directly to the mains via a simple power socket. This eliminates the unpleasant gas failure and saves the user from having to change the heavy cylinder regularly.
La conception de l'appareil veille à ce que l'ensemble de la partie électrique de celui-ci soit protégée des éventuelles projections de liquide.The design of the device ensures that the entire electrical part of the device is protected from any splashing liquid.
L'utilisateur est protégé contre les projections de verre en cas d'éclatement du tube par interposition d'une tôle permettant aussi de contenir les éventuels débris.The user is protected against splashing glass in case of bursting of the tube by interposition of a sheet also to contain any debris.
Il est aussi prévu un système de protection du tube contre les chocs en cas de chute de l'appareil par déformation de la double peau du réflecteur avant.It is also provided a protection system of the tube against shocks in case of falling from the device by deformation of the double skin of the front reflector.
Cette double peau permettant aussi la circulation d'air visant à refroidir la partie active de l'appareil.This double skin also allows air circulation to cool the active part of the device.
L'élément actif permettant de transformer l'énergie électrique en chaleur est un tube faisant appel à la technologie infrarouge à ondes courtes.The active element for transforming electrical energy into heat is a tube using shortwave infrared technology.
Les ondes thermiques à hautes fréquences traversent l'air sans l'échauffer et apportent ainsi, de manière précise et économique, la chaleur là où elle est nécessaire. Il en découle que ce type de chauffage est insensible aux courants d'air. Cette technologie est donc particulièrement bien adaptée pour une utilisation en plein air. Il chauffe uniquement les personnes et les objets se situant dans la zone de rayonnement de l'appareil. L'élément actif peut aussi faire appel à d'autres technologies qui pourraient lui conférer des caractéristiques différentes, adaptées à d'autres types d'utilisation.High-frequency thermal waves pass through the air without heating it and thus bring the heat precisely and economically where it is needed. It follows that this type of heating is insensitive to drafts. This technology is therefore particularly well suited for outdoor use. It heats only people and objects located in the radiation zone of the device. The active element can also use other technologies that could give it different characteristics, adapted to other types of use.
L'absence d'émission de gaz nocifs ou odorants ainsi que la non consommation d'oxygène rend possible l'utilisation de cet appareil pour assurer le chauffage en intérieur. Il peut aussi être utilisé pour chauffer un garage, un atelier, un hall ou un jardin d'hiver.The absence of emission of noxious or odorous gases as well as the non-consumption of oxygen makes it possible to use this appliance to provide indoor heating. It can also be used to heat a garage, a workshop, a hall or a winter garden.
L'appareil peut être utilisé sur différents supports en fonction du besoin de l'utilisateur : montage sur pied autonome, montage type parasol sur table de jardin et montage mural. Le pied autonome constitué d'un socle massif et d'un tube cintré dans lequel passe le câble d'alimentation permet à l'utilisateur d'installer l'appareil à sa guise pourvu que le sol soit lisse et horizontal. La fixation murale est conseillée pour les lieux nécessitant un chauffage régulier et permet de ne pas encombrer le sol. Tous ces supports bénéficient d'une fonction permettant l'orientation de l'appareil. Cette fonction a pour but de laisser à l'utilisateur la possibilité de modifier la zone de rayonnement sans avoir à déplacer l'ensemble de l'appareil.The device can be used on different supports depending on the user's needs: stand-alone stand-up mounting, parasol-type mounting on a garden table and wall mounting. The stand-alone foot consisting of a solid base and a bent tube through which the power cable passes allows the user to install the device as it pleased provided that the ground is smooth and horizontal. The wall mounting is recommended for places requiring regular heating and can not clutter the ground. All these supports have a function for the orientation of the device. This function is intended to give the user the ability to change the radiation area without having to move the entire unit.
Le design innovant de cet appareil s'appuie sur l'utilisation de deux réflecteurs montés en opposition et dont les formes complexes permettent une répartition particulièrement homogène et confortable du rayonnement à l'intérieur de la zone de chauffage. Cette disposition permet de dissimuler des regards la partie chauffante, offrant ainsi un aspect agréable et élégant à l'appareil. Cette caractéristique permet aussi de s'affranchir de l'utilisation de grille de protection ou de vitre.The innovative design of this device is based on the use of two opposing reflectors whose complex shapes allow a particularly homogeneous and comfortable distribution of the radiation inside the heating zone. This arrangement allows to hide the eyes heating part, thus providing a nice and elegant appearance to the device. This feature also eliminates the use of protective grid or glass.
L'appareil est équipé d'un système de réglage du mode de diffusion de la chaleur par modification de la géométrie du réflecteur principal. Pour ce faire, l'appareil est équipé d'une poignée dont la forme est intégrée au design général. L'ossature de l'appareil est constituée d'un châssis reliant deux pièces sur lesquelles viennent se greffer les deux réflecteurs ainsi que le module contenant l'élément chauffant.The apparatus is equipped with a system for adjusting the heat diffusion mode by modifying the geometry of the main reflector. To do this, the device is equipped with a handle whose shape is integrated in the general design. The frame of the apparatus consists of a frame connecting two parts on which are grafted the two reflectors and the module containing the heating element.
Ce module est rapidement démontable du reste de l'appareil permettant ainsi de faciliter le remplacement de celui-ci. L'ensemble est recouvert d'une carrosserie conférant à l'ensemble toute sa rigidité.This module is quickly removable from the rest of the device thus facilitating the replacement of it. The whole is covered with a body giving all the rigidity.
Cette architecture très simple offre à l'appareil une fiabilité de premier ordre et réduit sensiblement le coût et la durée de maintenance. Dans la mesure du possible, les éléments constituant l'appareil sont fabriqués avec des matériaux capables de résister au mieux aux effets climatiques.This very simple architecture provides the device with first-class reliability and significantly reduces the cost and maintenance time. Whenever possible, the components of the device are made of materials that can best withstand the effects of climate.
L'invention concerne un appareil électrique de chauffage. L'invention a pour but d'améliorer une qualité de chauffage. L'invention concerne le domaine des appareils de chauffage utilisés en extérieur comme en intérieur.The invention relates to an electric heating apparatus. The invention aims to improve a heating quality. The invention relates to the field of heaters used outdoors and indoors.
Il est connu de l'état de la technique des appareils de chauffage comportant un élément radiant halogène et un premier organe réfléchissant.It is known from the state of the art of the heaters comprising a halogenated radiant element and a first reflecting member.
L'élément radiant halogène est une source à infra rouge et est relié à une source d'alimentation électrique. L'élément radiant est destiné à émettre une énergie susceptible d'être réfléchie sur et par le premier organe réfléchissant. L'élément radiant est également susceptible de chauffer une zone à chauffer directement et indirectement par l'intermédiaire de l'organe réfléchissant. La zone à chauffer est une surface du sol recevant les rayonnements de l'appareil. Le problème est que l'élément radiant est éblouissant pour l'utilisateur.The halogenated radiant element is an infrared source and is connected to a power source. The radiant element is intended to emit energy that can be reflected on and by the first reflecting member. The radiant element is also capable of heating an area to be heated directly and indirectly via the reflecting member. The zone to be heated is a surface of the ground receiving the radiations of the apparatus. The problem is that the radiant element is dazzling for the user.
L'utilisateur est obligé de se placer dos à l'appareil, ce qui n'est pas toujours aisé de faire lorsqu'on se situe sur une terrasse de café et qu'on est plusieurs consommateurs installés.The user is obliged to stand back to the device, which is not always easy to do when you are on a terrace of coffee and there are several consumers installed.
Dans l'invention, il est prévu de rendre invisible l'élément radiant du regard des utilisateurs en plaçant l'élément radiant dans une coque de réflexion. Cette coque de réflexion est réalisée de telle manière qu'elle est susceptible d'émettre une chaleur thermique après que cette coque ait été exposée à des rayonnements émis par l'élément radiant. De plus cette coque est réalisée de telle manière qu'elle est également susceptible de retransmettre les rayonnements émis par l'élément radiant sur la coque en direction de l'organe réfléchissant. Ainsi, dans l'invention, il est également prévu de positionner l'organe réfléchissant au-dessus de l'élément radiant. Ainsi, selon l'invention, les rayonnements de l'élément radiant sont retransmis uniquement par l'intermédiaire de la surface réfléchissante et de la coque sous la forme de chaleur thermique et non plus sous la forme d'une chaleur provenant directement des rayonnements de l'élément radiant.In the invention, it is intended to make the radiating element invisible to users by placing the radiant element in a reflection shell. This reflection shell is made in such a way that it is capable of emitting thermal heat after this shell has been exposed to radiation emitted by the radiant element. Moreover this shell is made in such a way that it is also capable of retransmitting the radiation emitted by the radiating element on the shell in the direction of the reflecting member. Thus, in the invention, it is also intended to position the reflective member above the radiant element. Thus, according to the invention, the radiations of the radiant element are retransmitted solely via the reflecting surface and the shell in the form of thermal heat and no longer in the form of heat directly from the radiation of the radiant element.
De plus la surface réfléchissante reçoit non seulement les rayonnements provenant directement de l'élément radiant mais également les rayonnements provenant de la coque de réflexion.In addition, the reflecting surface receives not only the radiation coming directly from the radiant element but also the radiation coming from the reflection shell.
L'invention a donc pour objet un appareil électrique de chauffage comportantThe subject of the invention is therefore an electrical heating apparatus comprising

La figure 2 illustre un appareil électrique de chauffage 1 , selon l'invention. Cet appareil comporte au moins un élément radiant halogène 2 et un premier organe réfléchissant 3. Cet appareil comporte une tige ou un mât 17 qui est relié à l'élément radiant halogène 2 pour surélever l'élément radiant halogène 2 par rapport à un plan du sol, le sol étant un endroit sur lequel peut être placé l'appareil 1 en position de fonctionnement normal d'un tel appareil. L'élément radiant halogène 2 fait parti d'un ensemble monobloc qui peut être suspendu par l'intermédiaire du mât 17 ou fixé à un mur directement.FIG. 2 illustrates an electric heating apparatus 1, according to the invention. This apparatus comprises at least one halogenated radiant element 2 and a first reflective member 3. This apparatus comprises a rod or a mast 17 which is connected to the halogenated radiant element 2 to elevate the halogenated radiant element 2 relative to a plane of the ground, the ground being a place on which can be placed the device 1 in the normal operating position of such a device. The halogen radiant element 2 is part of a one-piece assembly that can be suspended via the mast 17 or attached to a wall directly.
L'élément radiant halogène 2 est relié à une source d'alimentation électrique pour chauffer une zone à chauffer. Une zone à chauffer peut être une terrasse d'un café par exemple. Le premier organe réfléchissant 3 est apte à recevoir et à réfléchir une énergie produite par l'élément radiant halogène 2. Le premier organe forme un réflecteur.The halogenated radiant element 2 is connected to a power source for heating an area to be heated. An area to be heated may be a terrace of a cafe for example. The first reflecting member 3 is adapted to receive and reflect energy produced by the halogenous radiant element 2. The first member forms a reflector.
Selon l'invention, l'appareil comporte également une coque de réflexion 4 dans laquelle est placée l'élément radiant halogène 2, figure 1. La coque 4 est formée par une plaque recourbée partiellement autour d'un axe horizontal 24, ledit axe étant dans un exemple figure 1 relativement parallèle à un plan du sol. Par relativement on entend que l'axe horizontal 24 peut être contenu dans un plan qui est incliné de plus ou moins 10° par rapport au plan du sol. La plaque formée par la coque 4 peut être formée d'un matériau en aluminium par exemple. L'élément radiant halogène 2 est placé dans un espace délimité par la coque 4. Plus précisément, la coque 4 est réalisée de telle manière que des rayonnements émis par l'élément radiant halogène 2 sont exclusivement dirigés sur une première surface réfléchissante 5 formée par le premier organe réfléchissant 3. La première surface 5 forme un premier réflecteur. Dans l'invention, le premier organe réfléchissant 3 est disposé au-dessus de l'élément radiant halogène 2 avec ladite première surface 5 disposée en regard de l'élément radiant halogène 2, figure 1. Dans un exemple, l'élément radiant halogène 2 est disposé coaxialement à l'axe 24. Mais l'élément radiant halogène 2 pourrait être disposé en dessous de l'axe 24, parallèlement à l'axe 24 entre la coque 4 et l'axe 24. En fait, l'élément radiant halogène 2 est disposé de telle manière que ce même élément radiant halogène 2 ne soit pas visible par un utilisateur de l'appareil.According to the invention, the apparatus also comprises a reflection shell 4 in which is placed the halogenous radiant element 2, FIG. 1. The shell 4 is formed by a plate curved partially around a horizontal axis 24, said axis being in an example Figure 1 relatively parallel to a plane of the ground. By relatively it is meant that the horizontal axis 24 may be contained in a plane which is inclined more or less 10 ° with respect to the plane of the ground. The plate formed by the shell 4 may be formed of an aluminum material for example. The halogenated radiant element 2 is placed in a space delimited by the shell 4. More specifically, the shell 4 is made in such a way that radiations emitted by the halogenated radiant element 2 are exclusively directed on a first reflecting surface 5 formed by the first reflective member 3. The first surface 5 forms a first reflector. In the invention, the first reflecting member 3 is disposed above the halogenous radiating element 2 with said first surface 5 disposed opposite the halogenated radiant element 2, FIG. 1. In one example, the halogenated radiant element 2 is arranged coaxially with the axis 24. But the halogenous radiant element 2 could be disposed below the axis 24, parallel to the axis 24 between the shell 4 and the axis 24. In fact, the element Halogen radiant 2 is arranged in such a way that the same halogenated radiant element 2 is not visible to a user of the apparatus.
L'appareil comporte un deuxième organe réfléchissant 6 disposé entre la coque 4 et l'élément radiant halogène 2. Mais le deuxième organe réfléchissant 6 pourrait être formé par la coque 4 (exemple non illustré). Le deuxième organe réfléchissant 6 comporte une deuxième surface réfléchissante 7. Cette deuxième surface 7 forme un réflecteur. La première surface réfléchissante 5 et la deuxième surface réfléchissante 7 comportent chacune une forme globalement concave tout en étant disposées l'une en regard de l'autre, sachant que l'élément radiant halogène est placé entre la première surface 5 et la deuxième surface 7. Le deuxième organe 6 est situé proche du sol tandis que le premier organe 3 est situé éloigné du sol longitudinalement par rapport à un axe vertical 1 1. L'axe vertical 1 1 est un axe qui passe par le premier organe 3, l'élément radiant halogène 2 et la coque de réflexion 4. Cet axe vertical 1 1 est perpendiculaire au plan formé par le sol. Ainsi, les rayonnements de la deuxième surface réfléchissante 7 provenant de l'élément radiant halogène 2 et les rayonnements provenant de l'élément radiant halogène 2 directement sont projetés sur la première surface réfléchissante 5. La première surface réfléchissante 5 émet alors des rayonnements thermiques sur la zone à chauffer qui résultent de ceux provenant directement de l'élément radiant et de ceux provenant de la deuxième surface réfléchissante.The apparatus comprises a second reflecting member 6 disposed between the shell 4 and the halogen radiating element 2. But the second reflecting member 6 could be formed by the shell 4 (example not shown). The second reflecting member 6 comprises a second reflecting surface 7. This second surface 7 forms a reflector. The first reflecting surface 5 and the second reflecting surface 7 each have a generally concave shape while being arranged facing each other, knowing that the halogenated radiant element is placed between the first surface 5 and the second surface 7 The second member 6 is located close to the ground while the first member 3 is located distant from the ground longitudinally relative to a vertical axis 1 1. The vertical axis 1 1 is an axis which passes through the first member 3, the halogenous radiant element 2 and reflection shell 4. This vertical axis 1 1 is perpendicular to the plane formed by the ground. Thus, the radiation of the second reflecting surface 7 coming from the halogenated radiant element 2 and the radiations coming from the halogenous radiant element 2 are projected directly onto the first reflecting surface 5. The first reflecting surface 5 then emits thermal radiation on the zone to be heated which result from those coming directly from the radiant element and from those coming from the second reflecting surface.
La coque de réflexion ou coque réfléchissante comporte une première remontée 28 et une deuxième remontée 29 liées entre elles par un fond 32 horizontal, ces remontées remontant en direction de la première surface réfléchissante 5 du premier organe réfléchissant, une des remontées remontant plus haut que l'autre par rapport à ce fond 32.The reflection shell or reflective shell comprises a first lift 28 and a second lift 29 interconnected by a horizontal bottom 32, these lifts going up towards the first reflecting surface 5 of the first reflecting member, one of the rising up higher than the other than that background 32.
La coque de réflexion est suffisamment écartée de l'élément radiant halogène pour que la température de cette coque soit inférieure ou égale à 100°C.The reflection shell is sufficiently spaced from the halogenated radiant element so that the temperature of this shell is less than or equal to 100 ° C.
Plusieurs éléments radiants halogène peuvent être disposés horizontalement et parallèlement les uns à côté des autres. L'élément radiant halogène 2 est, dans un exemple préféré, formé par un tube émettant un rayonnement à infrarouge. L'élément radiant halogène est disposé parallèlement à l'axe 24.Several halogen radiant elements can be arranged horizontally and parallel to each other. In a preferred example, the halogenated radiant element 2 is formed by a tube emitting infrared radiation. The halogenated radiant element is arranged parallel to the axis 24.
Le premier organe réfléchissant 3 comporte une première aile 8, une deuxième aile 9 et une pièce centrale 10. La première surface 5 peut être formée par la première aile 8, la deuxième aile 9 et la pièce centrale 10. La première aile 8 et la deuxième aile 9 sont articulées sur la pièce centrale 10. La pièce centrale 10 est située au dessus de l'élément radiant 2. La première aile 8 et la deuxième aile 9 sont situées de part et d'autre de la pièce centrale 10.The first reflecting member 3 comprises a first wing 8, a second wing 9 and a central piece 10. The first surface 5 may be formed by the first wing 8, the second wing 9 and the central piece 10. The first wing 8 and the second wing 9 are articulated on the central piece 10. The central piece 10 is located above the radiant element 2. The first wing 8 and the second wing 9 are located on either side of the central piece 10.
La première aile 8 et la deuxième aile 9 sont également formées chacune par une plaque qui est courbée. La plaque peut être métallique, en aluminium ou autre. La première aile et la deuxième aile forment avec la pièce centrale 10 une parabole inclinable positionnée au dessus de l'élément radiant halogène 2. Dans un exemple, chaque plaque formée par la première aile 8 et par la deuxième aile 9 comporte une forme globalement rectangulaire et forme un arc de cercle en coupe transversale de l'aile correspondante. Chaque arc de cercle est prolongé par la pièce centrale. En fait, le premier organe 3 forme en coupe transversale deux arcs de cercles dont le point d'inflexion des ces deux arcs est situé sur la pièce centrale 10. Le point d'inflexion est un endroit de la pièce centrale où se rejoignent les deux arcs de cercle. Le deuxième organe forme également globalement un arc de cercle en coupe transversale.The first wing 8 and the second wing 9 are each formed by a plate which is curved. The plate can be metal, aluminum or other. The first wing and the second wing form with the central piece 10 a tilting parabola positioned above the halogenous radiant element 2. In one example, each plate formed by the first wing 8 and the second wing 9 has a generally rectangular shape and forms a circular arc in cross section of the corresponding wing. Each arc is extended by the center piece. In fact, the first member 3 forms in cross section two arcs of circles whose point of inflection of these two arcs is located on the central piece 10. The point of inflection is a place in the central part where the two meet. arcs of circle. The second member also generally forms a circular arc in cross section.
Ou bien, le premier organe réfléchissant comporte la première aile et la deuxième aile qui s'articulent l'une par rapport à l'autre tout en étant situées l'une en dessous de l'autre (exemple non illustré). Le premier organe 3 comporte également un premier support d'aile 18 et un deuxième support d'aile 19, figure 3. Le premier support d'aile et le deuxième support d'aile sont placés respectivement entre la première aile 8 et la pièce centrale 10 d'une part, et entre la pièce centrale 10 et la deuxième aile 9 d'autre part. La première aile 8 et la deuxième aile 9 sont reliées à la pièce centrale 10 par l'intermédiaire respectivement du premier support d'aile 18 et du deuxième support d'aile 19. Le premier support 18 et le deuxième support 19 comportent respectivement un premier bras 20 et un deuxième bras 21 s'étendant transversalement à une extrémité de la première aile 8 et à une extrémité de la deuxième aile 9 en direction de la coque 4 tout en ayant tendance à se rejoindre.Or, the first reflective member comprises the first wing and the second wing which are articulated relative to each other while being located one below the other (example not shown). The first member 3 also comprises a first wing support 18 and a second wing support 19, FIG. 3. The first wing support and the second wing support are placed respectively between the first wing 8 and the central piece. 10 on the one hand, and between the central piece 10 and the second wing 9 on the other hand. The first wing 8 and the second wing 9 are connected to the central piece 10 via respectively the first wing support 18 and the second wing support 19. The first support 18 and the second support 19 respectively comprise a first arm 20 and a second arm 21 extending transversely at one end of the first flange 8 and at one end of the second flange 9 towards the shell 4 while having a tendency to meet.
La première aile 8 et la deuxième aile 9 sont articulées au moyen d'une came 12. La came 12 est disposée transversalement par rapport à la première aile 8 et par rapport à la deuxième aile 9. La came 12 permet d'articuler la première aile 8 et la deuxième aile 9 par rapport à la pièce centrale 10. La came 12 permet de rapprocher ou d'éloigner la première aile et la deuxième aile de l'élément radiant tout en contrôlant une intensité de chauffage de la zone à chauffer.The first wing 8 and the second wing 9 are articulated by means of a cam 12. The cam 12 is disposed transversely with respect to the first wing 8 and with respect to the second wing 9. The cam 12 makes it possible to articulate the first wing 9 wing 8 and the second wing 9 relative to the central piece 10. The cam 12 allows to move the first wing closer or away and the second wing of the radiant element while controlling a heating intensity of the zone to be heated.
Pour ce faire, la came 12 est reliée au premier bras 20 et au deuxième bras 21. Le premier bras 20 et le deuxième bras 21 comportent, à cet effet, respectivement un premier picot 15 et un deuxième picot 16. Chacun de ces picots s'étend relativement parallèlement à l'axe 24. La came 12 comporte un premier orifice 13 et un deuxième orifice 14 au travers desquels s'insèrent le premier picot 15 et le deuxième picot 16 respectivement pour faire déplacer la première aile 8 et la deuxième aile 9. La came 12 coopère avec le premier picot 15 et avec le deuxième picot 16 de telle manière que la première aile 8 et la deuxième aile 9 sont inclinables en direction de l'élément radiant halogène 2. La première aile 8 et la deuxième aile 9 sont inclinables en même temps de manière à concentrer ou au contraire à diluer une intensité de chauffage sur la zone à chauffer donnée. Le premier picot 15 et le deuxième picot 16 sont destinés à venir se placer en appui contre un bord formé respectivement par le premier orifice 13 et par le deuxième orifice 14 de la came. Ce qui fait que lorsque la came 12 est mise en rotation autour d'un axe parallèle à l'axe 24, un rapprochement ou un éloignement de la première aile 8 et de la deuxième aile 9 l'une par rapport à l'autre par l'intermédiaire respectivement du premier support 18 et du deuxième support 19 est provoqué.To do this, the cam 12 is connected to the first arm 20 and the second arm 21. The first arm 20 and the second arm 21 comprise, for this purpose, respectively a first pin 15 and a second pin 16. Each of these pins extends relatively parallel to the axis 24. The cam 12 has a first orifice 13 and a second orifice 14 through which the first pin 15 and the second pin 16 fit respectively to move the first wing 8 and the second wing 9. The cam 12 cooperates with the first pin 15 and with the second pin 16 so that the first wing 8 and the second wing 9 are tiltable towards the halogen radiating element 2. The first wing 8 and the second wing 9 are tiltable at the same time so as to concentrate or on the contrary to dilute a heating intensity on the given zone to be heated. The first pin 15 and the second pin 16 are intended to be placed in abutment against an edge respectively formed by the first hole 13 and the second hole 14 of the cam. As a result, when the cam 12 is rotated about an axis parallel to the axis 24, the first wing 8 and the second wing 9 are brought together relative to one another by the intermediate respectively of the first support 18 and the second support 19 is caused.
Chacun des orifice 13 et 14 comporte une forme oblong courbée autour d'un axe parallèle à l'axe horizontal 24. La came 12 peut être poussée par un côté avec le premier picot placé en appui contre un rebord formé à une partie haute du premier orifice 13 et le deuxième picot placé en appui contre un autre rebord formé à une partie basse du deuxième orifice. Ou bien inversement, la came peut être poussée par un côté opposé avec le premier picot placé en appui contre un rebord à une partie basse du premier orifice et le deuxième picot placé en appui contre un autre rebord à une partie haute de ce deuxième orifice. Ainsi, la came peut être accessible à un utilisateur d'un côté ou de l'autre de l'appareil. Il peut être prévu une butée d'arrêt (non représentée) formée par la came, cette butée étant apte à venir en appui contre un épaulement pour bloquer la came et donc pour bloquer une ouverture de la première et de la deuxième aile selon une position donnée. Pour relier le premier organe réfléchissant à la coque 4, au moins une clef supérieure 22 et au moins une clef inférieure 23 sont disposées transversalement par rapport respectivement au premier organe réfléchissant 3 et à la coque 4. Dans un exemple, une première clef supérieur 22 et une deuxième clef supérieure 30 sont fixées transversalement et de part et d'autre du premier support, de la pièce centrale et du deuxième support. Une première clef inférieure 23 et une deuxième clef inférieure 31 sont également disposées transversalement et de part et d'autre de la coque et éventuellement du deuxième organe réfléchissant. Les clefs supérieures et les clefs inférieures coopère les unes avec les autres tout en s'emboîtant les unes en correspondance des autres. Par exemple, chacune des clefs supérieures forme une partie femelle et chacune des clefs inférieures forme une partie mâle ou broche, la partie mâle étant destinée à s'emboîter dans la partie femelle. La came 12 est destinée à être fixée sur une clef supérieure ou sur une clef inférieure. Dans l'exemple figure 1 , la came est fixée à la deuxième clef supérieure 30 par son axe de rotation 27. La came comporte un axe de rotation 27 par l'intermédiaire duquel la came 12 s'articule à la clef supérieure correspondante pour faire basculer la première aile et la deuxième aile. Chacune des clefs comporte une forme globalement en Y. Chacune des clefs supérieures supporte la came 12 tandis que chacune des clefs inférieures supporte l'élément radiant 2.Each of the openings 13 and 14 has an oblong shape bent around an axis parallel to the horizontal axis 24. The cam 12 can be pushed by one side with the first pin placed in abutment against a rim formed at an upper part of the first orifice 13 and the second pin placed in abutment against another rim formed at a lower part of the second orifice. Or conversely, the cam can be pushed by an opposite side with the first pin placed in abutment against a flange at a lower portion of the first orifice and the second pin placed in abutment against another flange at an upper portion of the second orifice. Thus, the cam can be accessible to a user on one side or the other of the apparatus. It can be provided a stop (not shown) formed by the cam, this stop being able to bear against a shoulder to block the cam and thus to block an opening of the first and second wing in a position given. To connect the first reflecting member to the shell 4, at least one upper key 22 and at least one lower key 23 are arranged transversely with respect to the first reflecting member 3 and the shell 4, respectively. In one example, a first top key 22 and a second upper key 30 are fixed transversely and on either side of the first support, the central piece and the second support. A first lower key 23 and a second lower key 31 are also arranged transversely and on either side of the shell and possibly the second reflecting member. The upper keys and the lower keys cooperate with each other while fitting one another in correspondence with the others. For example, each of the upper keys forms a female part and each of the lower keys forms a male part or pin, the male part being intended to fit into the female part. The cam 12 is intended to be fixed on an upper key or on a lower key. In the example in FIG. 1, the cam is fixed to the second upper key 30 by its axis of rotation 27. The cam comprises an axis of rotation 27 through which the cam 12 articulates with the corresponding upper key to make swing the first wing and the second wing. Each of the keys has a shape generally Y. Each of the upper keys supports the cam 12 while each of the lower keys supports the radiant element 2.
L'élément radiant halogène 2 est fixé à une extrémité à la première clef inférieure 23 et est fixé à une extrémité opposée la deuxième clef inférieure 31 , longitudinalement par rapport à l'axe 24. Au-dessus de la pièce centrale, de la première aile et de la deuxième aile est disposée une cage rigide 26 et une enveloppe de protection 25, l'enveloppe recouvrant la première aile, la deuxième aile et la cage rigide. L'enveloppe protège l'élément radiant.The halogenous radiant element 2 is fixed at one end to the first lower key 23 and is fixed at an opposite end to the second lower key 31, longitudinally with respect to the axis 24. Above the central piece, the first wing and the second wing is disposed a rigid cage 26 and a protective envelope 25, the casing covering the first wing, the second wing and the rigid cage. The envelope protects the radiant element.
Le mât 17 est fixé à un ensemble monobloc, l'ensemble monobloc étant formé par le premier organe réfléchissant 3, la coque de réflexion 4, l'élément radiant halogène, éventuellement le deuxième organe réfléchissant et chacune des clefs supérieures et chacune des clefs inférieures, figure 4. Cet ensemble monobloc est facilement démontable du mât pour le remplacer par un autre, dans le cas par exemple où l'élément radiant halogène ou une des surface réfléchissante seraient usés. La première surface réfléchissante 5 peut être formée par une multitude de facettes inclinées différemment les unes par rapport aux autres.The mast 17 is fixed to a one-piece assembly, the one-piece assembly being formed by the first reflecting member 3, the reflecting shell 4, the halogenating radiant element, possibly the second reflecting member and each of the upper keys and each lower key. This single-piece assembly is easily removable from the mast to replace it with another, in the case for example where the halogenous radiant element or a reflective surface would be worn. The first reflecting surface 5 can be formed by a multitude of facets inclined differently relative to each other.
L'inclinaison des facettes permet de diminuer un éblouissement qui résulterait de la réflexion de l'élément radiant halogène sur le premier organe réfléchissant.The inclination of the facets makes it possible to reduce a glare that would result from the reflection of the halogenated radiant element on the first reflecting member.
