Description détaillée de modes de réalisation de l'inventionDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Les figures 1 et 2 illustrent un radiateur 1 de l'art antérieur. Le radiateur 1 comporte un carter 2 et au moins un élément chauffant 3. Le carter 2 est formé par une paroi frontale ou façade avant 4, une paroi arrière 5, une paroi supérieure 6 pleine, une paroi inférieure ou fond 7 et deux parois latérales. Le carter 2 délimite au moins une chambre de chauffage 8 dans laquelle peut être disposé l'élément chauffant 3. Cet élément chauffant 3 peut être situé à un endroit proche du fond 7 et éloignée de la paroi supérieure 6. Cet élément chauffant 3 est destiné à chauffer l'une au moins des parois supérieure 6, latérales, inférieure 7 et/ou frontale 4.The Figures 1 and 2 illustrate a radiator 1 of the prior art. The radiator 1 comprises a housing 2 and at least one heating element 3. The housing 2 is formed by a front wall or front wall 4, a rear wall 5, a solid upper wall 6, a bottom wall or bottom wall 7 and two side walls. . The casing 2 delimits at least one heating chamber 8 in which the heating element 3 can be arranged. This heating element 3 can be located at a place near the bottom 7 and away from the top wall 6. This heating element 3 is intended to to heat at least one of the upper 6, side, bottom 7 and / or front walls 4.

Dans l'exemple considéré, l'élément chauffant 3 est électrique, et comporte une ou plusieurs résistances électriques chauffantes reliées à une alimentation électrique (non représentée). Toutefois, l'élément chauffant 3 pourrait être éventuellement de tout autre type connu, et pourrait par exemple consister en une série d'ailettes en contact thermique avec un conduit dans lequel circule de l'eau chaude ou un autre fluide caloporteur de chaud.In the example, the heating element 3 is electric, and comprises one or more electric heating resistors connected to a power supply (not shown). However, the heating element 3 could possibly be of any other known type, and could for example consist of a series of fins in thermal contact with a conduit in which circulates hot water or other heat transfer fluid of hot.

Dans l'exemple considéré figure 2, le carter 2 est sensiblement parallélépipédique. La paroi arrière 5 est pleine et est disposée parallèlement et verticalement par rapport à un plan d'un mur 9 de la pièce à chauffer. Le carter 2 est fixé au mur à l'aide de moyens de fixation 54. Les moyens de fixation 54 lient la paroi arrière 5 au mur 9 de manière à accrocher le radiateur au mur 9. Une entrée d'air 43 est ménagée dans le fond 7, sur la majeure partie de la longueur de ce fond 7. Le carter forme un premier volet de renvoi 10 délimitant avec la paroi frontale 4 une première sortie d'air 12. Cette première sortie d'air 12 est localisée à une partie haute du radiateur.In the example considered figure 2 , the casing 2 is substantially parallelepipedic. The rear wall 5 is solid and is arranged parallel and vertically with respect to a plane of a wall 9 of the room to be heated. The casing 2 is fixed to the wall by means of fixing means 54. The fixing means 54 connect the rear wall 5 to the wall 9 so as to hook the radiator to the wall 9. An air inlet 43 is formed in the bottom 7, over most of the length of the bottom 7. The housing forms a first return flap 10 delimiting with the front wall 4 a first air outlet 12. This first air outlet 12 is located at a part high of the radiator.

Lorsque l'élément chauffant 3 est alimenté en courant électrique, un flux d'air ambiant est aspiré par l'entrée d'air 43, chauffé par l'élément chauffant 3, puis ce flux d'air monte dans la chambre 8, et sors par la sortie d'air 12.When the heating element 3 is supplied with electric current, a flow of ambient air is sucked by the air inlet 43, heated by the heating element 3, then this air flow rises in the chamber 8, and leave by the air outlet 12.

Selon la figure 2, le premier volet 10 s'étend en avant de la paroi frontale 4. Le premier volet de renvoi 10 est décalé de la paroi frontale 4. La première sortie d'air 12 est délimitée par ce premier volet 10 et par une extrémité supérieure 11 de la paroi frontale 4. En fait, le premier volet de renvoi 10 est formé par la paroi supérieure 6. La paroi supérieure 6 est prolongée en avant de la paroi frontale 4, en direction opposée au mur 9 pour former le premier volet de renvoi 10. La paroi supérieure 6 s'étend au-dessus et en avant de la paroi frontale 4 de telle manière qu'un espace 44 est délimité entre l'extrémité supérieure 11 de la paroi frontale 4 et la paroi supérieure 6. Le premier volet de renvoi 10 est formé par une portion 10.1 de la paroi supérieure 6, ladite portion débordant en avant de la paroi frontale 4. Cette portion de paroi supérieure 6 est pliée de telle sorte qu'elle forme un bord 10.1, ledit bord 10.1 s'étendant dans un plan sensiblement parallèle à un plan dans lequel s'étend la paroi frontale 4 et s'étendant dans un autre plan qui est sensiblement perpendiculaire par rapport au reste de la paroi supérieure 6. Par sensiblement parallèle, on entend que le premier volet de renvoi 10 s'étend dans un plan qui est parallèle à plus ou moins 5° par rapport à un autre plan dans lequel s'étend la paroi frontale 4. Par sensiblement perpendiculaire, on entend que le premier volet de renvoi 10 s'étend dans un plan qui est perpendiculaire à plus ou moins 5° par rapport à un autre plan dans lequel s'étend le reste de la paroi supérieure 6.According to figure 2 the first flap 10 extends forward of the front wall 4. The first flap 10 is offset from the front wall 4. The first air outlet 12 is delimited by this first flap 10 and an upper end 11 of the front wall 4. In fact, the first return flap 10 is formed by the upper wall 6. The upper wall 6 is extended forward of the front wall 4, in the opposite direction to the wall 9 to form the first return flap 10. The upper wall 6 extends above and in front of the front wall 4 so that a space 44 is delimited between the upper end 11 of the front wall 4 and the top wall 6. The first shutter 10 is formed by a portion 10.1 of the upper wall 6, said portion protruding forward of the front wall 4. This upper wall portion 6 is folded so that it forms an edge 10.1, said edge 10.1 extending in a substantially parallel plane to a plane in which the front wall 4 extends and extends in another plane which is substantially perpendicular to the remainder of the upper wall 6. By substantially parallel means that the first return flap 10 extends in a plane which is parallel to plus or minus 5 ° with respect to another plane in which the front wall 4 extends. By substantially perpendicular means that the first return flap 10 extends in a plane which is perpendicular at plus or minus 5 ° with respect to another plane in which the remainder of the upper wall 6 extends.

Dans l'exemple figure 2, le plan dans lequel s'étend la paroi frontale 4 est positionnée par rapport au plan du mur légèrement en biais et en direction du mur de bas en haut. Le premier volet de renvoi 10 s'étend donc par son bord 10.1 également dans un plan qui est légèrement en biais et en direction du mur de bas en haut.In the example figure 2 , the plane in which the front wall 4 extends is positioned in relation to the wall plane slightly at an angle and towards the wall from bottom to top. The first return flap 10 therefore extends by its edge 10.1 also in a plane which is slightly at an angle and towards the wall from bottom to top.

La paroi frontale 4 est inclinée de telle manière que la chambre 8 forme, en coupe transversale, un conduit qui est rétrécit au sommet de cette chambre 8. Selon cette première variante, l'évacuation de l'air par l'entrée d'air 12 s'effectue donc à un endroit proche de la paroi supérieure 6 et en direction du sol.The front wall 4 is inclined in such a way that the chamber 8 forms, in cross-section, a duct which is narrowed at the top of this chamber 8. According to this first variant, the evacuation of the air by the air inlet 12 is therefore carried out at a location near the upper wall 6 and towards the ground.

La paroi supérieure 6 peut être revêtue intérieurement partiellement d'une paroi arrondie 56. Cette paroi arrondie 56 forme un demi-conduit positionné avec une face interne 55 de ce demi-conduit placée en regard de l'extrémité supérieure 11 de la paroi frontale 4. Cette paroi arrondie 56 est placée en regard ou en appui contre une face interne 46 du premier volet de renvoi 10 et éventuellement contre une face interne du reste de la paroi supérieure 6. La paroi arrondie 56 est placée en regard ou en appui contre le premier volet et contre la paroi supérieure par une face externe 45 de cette paroi arrondie 56. La face interne du reste de la paroi supérieure 6 se confond avec la face interne 46 du premier volet de renvoi 10. Par sa forme arrondie, cette paroi 56 forme un guide de passage de l'air pour canaliser l'air et faciliter l'évacuation de l'air de la chambre 8.The upper wall 6 may be partially internally coated with a rounded wall 56. This rounded wall 56 forms a half-duct positioned with an inner face 55 of this half-pipe placed facing the upper end 11 of the front wall 4 This rounded wall 56 is placed opposite or in abutment against an inner face 46 of the first return flap 10 and possibly against an inner face of the remainder of the upper wall 6. The rounded wall 56 is placed facing or resting against the first flap and against the upper wall by an outer face 45 of this rounded wall 56. The inner face of the remainder of the upper wall 6 merges with the inner face 46 of the first return flap 10. By its rounded shape, this wall 56 forms an air passage guide for channeling the air and facilitating the evacuation of air from the chamber 8.

Dans un exemple, la première sortie d'air 12 mesure 25 mm le long d'un axe passant par l'extrémité supérieure 11 de la paroi frontale 4 et par une extrémité 57 du premier volet de renvoi 10, l'axe étant sensiblement parallèle au plan du sol.In one example, the first air outlet 12 measures 25 mm along an axis passing through the upper end 11 of the end wall 4 and by an end 57 of the first return flap 10, the axis being substantially parallel on the ground plan.

L'extrémité 57 du premier volet de renvoi 10 et l'extrémité supérieure 11 de la paroi frontale 4 s'étendent en direction l'un de l'autre au moins jusqu'à un même plan, ledit plan étant sensiblement parallèle au plan du sol. Par sensiblement parallèle, on entend que le plan peut être incliné à plus ou moins 5° par rapport à un plan qui serait parallèle au plan du sol. Mais l'extrémité 57 du premier volet de renvoi 10 pourrait s'étendre en direction du sol, au-delà du plan parallèle au plan du sol tout en surplombant la paroi frontale 4.The end 57 of the first return flap 10 and the upper end 11 of the front wall 4 extend in the direction of one another at least to the same plane, said plane being substantially parallel to the plane of the ground. By substantially parallel means that the plane can be inclined to plus or minus 5 ° with respect to a plane that would be parallel to the ground plane. But the end 57 of the first return flap 10 could extend towards the ground, beyond the plane parallel to the plane of the ground while overlooking the front wall 4.

Selon une réalisation de l'invention, figures 3a et 3b, un radiateur 13 peut être formé. La figure 3a illustre schématiquement ce radiateur 13 selon une vue de face. La figure 3b illustre schématiquement ce radiateur 13 selon une coupe longitudinale. Ce radiateur 13 permet d'évacuer l'air selon une direction opposée au sol. Ce radiateur 13 comporte une paroi supérieure 65 et un fond 15. Un deuxième volet de renvoi 14 est formé par le fond 15 de ce radiateur 13. De la même manière que pour le radiateur 1 selon la première variante figure 2, le fond 15 de ce radiateur 13 s'étend en avant d'une paroi frontale 35 de ce radiateur 13 tout en s'étendant parallèlement à cette même paroi frontale 35 pour former le deuxième volet de renvoi 14. Même s'il n'est pas représenté, une paroi arrondie telle que celle illustrée figure 2 peut être disposée également en appui intérieurement contre le deuxième volet de renvoi 14. Ce radiateur 13 comporte une paroi interne 49 disposée en biais à partir du fond 15 et inclinée en direction du mur, de bas en haut. L'air pénètre entre cette paroi interne 49 et une paroi arrière 58 puis transite entre la paroi interne 49 et une paroi supérieure 65, puis entre la paroi interne 49 et la paroi frontale 35 pour sortir entre la paroi frontale 35 et le deuxième volet de renvoi 14.According to one embodiment of the invention, Figures 3a and 3b a radiator 13 can be formed. The figure 3a schematically illustrates this radiator 13 according to a front view. The figure 3b schematically illustrates this radiator 13 according to a longitudinal section. This radiator 13 makes it possible to evacuate the air in a direction opposite to the ground. This radiator 13 comprises an upper wall 65 and a bottom 15. A second return flap 14 is formed by the bottom 15 of this radiator 13. In the same way as for the radiator 1 according to the first variant figure 2 , the bottom 15 of this radiator 13 extends forward of a front wall 35 of the radiator 13 while extending parallel to the same end wall 35 to form the second return flap 14. Even if it is not shown, a rounded wall as illustrated figure 2 may also be disposed inwardly against the second return flap 14. This radiator 13 has an inner wall 49 disposed at an angle from the bottom 15 and inclined towards the wall, from bottom to top. The air enters between this inner wall 49 and a rear wall 58 and then passes between the inner wall 49 and an upper wall 65, then between the inner wall 49 and the front wall 35 to exit between the front wall 35 and the second flap of reference 14.

Le radiateur tel qu'illustré figure 2 pourrait comporter également un volet de renvoi inférieur, formé par le fond 7 (non illustré). Dans ce cas, la paroi frontale 4 sera alors jointive aux parois latérales du radiateur.The radiator as illustrated figure 2 could also include a lower return flap, formed by the bottom 7 (not shown). In this case, the front wall 4 will then be joined to the side walls of the radiator.

Selon une variante de réalisation de l'invention figures 4a et 4b, un autre radiateur 21 peut être formé. La figure 4a illustre schématiquement cet autre radiateur 21 selon une vue de face. La figure 4b illustre schématiquement cet autre radiateur 21 selon une coupe longitudinale. Une paroi supérieure 22 forme un quatrième volet de renvoi de renvoi 24 et une paroi inférieure 23 forme un cinquième volet de renvoi 25. La paroi supérieure 22 et la paroi inférieure 23 s'étendent en avant d'une paroi frontale 34, en direction opposée au mur pour former respectivement le quatrième volet 24 et le cinquième volet 25. Une première évacuation de l'air s'effectue entre le quatrième volet de renvoi 24 et la paroi frontale 34, en direction du sol. Une seconde évacuation de l'air s'effectue entre le cinquième volet de renvoi 25 et la paroi frontale 34, en direction opposée au sol. Une paroi interne 59 s'étend en biais en direction du mur, de bas en haut et délimite avec une paroi arrière 60 une entrée d'air. La paroi interne 59 peut être également jointive avec des parois latérales de ce radiateur 21 et/ou avec la paroi inférieure 23. Une paroi intermédiaire 61 disposée au-dessus la paroi interne 59 pour former en coupe longitudinale une forme en U à cheval sur la paroi interne 59. Cette paroi intermédiaire 61 forme la paroi frontale en avant de la paroi interne 29. Cette paroi intermédiaire 61 formant la paroi frontale 34 délimite avec la paroi arrière 60 un premier conduit d'air 63, l'air y circulant étant destiné à sortir par la première évacuation d'air. Cette paroi intermédiaire 61 délimite un second conduit d'air 62 avec la paroi interne, l'air y circulant étant destiné à sortir par la seconde évacuation d'air. La paroi intermédiaire 61 est jointive également aux parois latérales.According to an alternative embodiment of the invention Figures 4a and 4b another radiator 21 may be formed. The figure 4a schematically illustrates this other radiator 21 according to a front view. The figure 4b schematically illustrates this other radiator 21 in a longitudinal section. An upper wall 22 forms a fourth deflection return flap 24 and a lower wall 23 forms a fifth flap 25. The upper wall 22 and the lower wall 23 extend forwardly of a front wall 34, in the opposite direction to the wall to form respectively the fourth flap 24 and the fifth flap 25. A first air evacuation is performed between the fourth flap 24 and the front wall 34, towards the ground. A second evacuation of the air is effected between the fifth return flap 25 and the front wall 34, in the opposite direction to the ground. An inner wall 59 extends obliquely towards the wall from bottom to top and delimits with a rear wall 60 an air inlet. The inner wall 59 may also be contiguous with side walls of this radiator 21 and / or with the bottom wall 23. An intermediate wall 61 disposed above the inner wall 59 to form in longitudinal section a U-shape straddling the internal wall 59. This intermediate wall 61 forms the front wall in front of the inner wall 29. This intermediate wall 61 forming the front wall 34 defines with the rear wall 60 a first air duct 63, the air flowing there being intended to exit by the first air outlet. This intermediate wall 61 defines a second air duct 62 with the inner wall, the air flowing there being intended to exit by the second air outlet. The intermediate wall 61 is also contiguous to the side walls.
