Description

La présente invention concerne les radiateurs sèche-serviettes comprenant plusieurs tubes émetteurs écartés les uns des autres, ainsi que deux tubes collecteurs en liaison chacun avec une extrémité de chacun des tubes émetteurs. Elle concerne plus particulièrement le raccordement d'un tel radiateur sèche-serviettes à des conduits d'arrivée et de retour d'un fluide caloporteur.The present invention relates to towel rail radiators comprising several emitter tubes spaced from each other, and two collector tubes each connected with one end of each of the emitter tubes. It relates more particularly to the connection of such a towel rail radiator to the inlet ducts and return of a heat transfer fluid.

On connaît de tels radiateurs sèche-serviettes à dispositif de raccordement central, c'est-à-dire pouvant être raccordés avec des conduits d'arrivée et de retour du fluide caloporteur qui débouchent à la partie centrale du radiateur. Sur ces radiateurs sèche-serviettes connus, des éléments du dispositif de raccordement central sont positionnés sur les deux premiers tubes émetteurs du radiateur, l'un reliant le premier tube émetteur au conduit de retour du fluide caloporteur, et l'autre reliant le deuxième tube émetteur au conduit d'arrivée du fluide caloporteur.There are known such towel rail radiators with central connection device, that is to say, can be connected with heat transfer fluid inlet and return pipes that open to the central part of the radiator. On these known towel radiators, elements of the central connection device are positioned on the first two emitting tubes of the radiator, one connecting the first emitter tube to the heat transfer fluid return pipe, and the other connecting the second tube. transmitter to the heat transfer fluid inlet duct.

Cette disposition connue oblige à forcer l'irrigation du radiateur sèche-serviettes en supprimant le premier trou de perçage du collecteur gauche et le deuxième trou de perçage du collecteur droit, ce qui rend la fabrication du radiateur plus complexe et moins efficace.This known arrangement requires forcing the irrigation of the towel rail radiator by removing the first drilling hole of the left collector and the second piercing hole of the right collector, which makes the manufacture of the radiator more complex and less effective.

De plus, de par leur conception, les radiateurs sèche-serviettes connus à raccordement central ont leurs éléments de raccordement disposés derrière les deux premiers tubes émetteurs, ce qui nuit à l'esthétique du radiateur, augmente la profondeur de celui-ci et rend le robinet de raccordement difficilement accessible pour l'utilisateur.In addition, by their design, the known central connection towel radiators have their connecting elements disposed behind the first two emitting tubes, which affects the aesthetics of the radiator, increases the depth thereof and makes the radiator connection tap difficult to access for the user.

La présente invention a pour objet de remédier aux inconvénients ci-dessus des radiateurs sèche-serviettes connus à raccordement central, et elle propose à cet effet un radiateur sèche-serviettes à raccordement central qui, tout en étant de fabrication simple et économique, grâce à l'utilisation de raccords moins onéreux, présente une esthétique améliorée tout en ayant les avantages d'une profondeur réduite et d'une position du robinet de raccordement plus accessible pour l'utilisateur.The object of the present invention is to overcome the above drawbacks of known central-connection towel warmers, and it proposes for this purpose a central-connection towel warmer which, while being simple and economical to manufacture, thanks to the use of less expensive fittings, has improved aesthetics while having the advantages of reduced depth and a position of the connection valve more accessible to the user.

A cet effet, le dispositif de raccordement central selon l'invention d'un radiateur sèche-serviettes à des tuyauteries d'arrivée et de retour d'un fluide caloporteur, est du type comprenant deux éléments de raccordement qui coopèrent chacun de façon étanche avec une ouverture disposée en partie centrale d'un tube émetteur du radiateur sèche-serviettes. Il se caractérise en ce que les deux éléments de raccordement sont indépendants l'un de l'autre et coopèrent chacun avec une ouverture ménagée dans la partie centrale du tube émetteur inférieur, entre les deux ouvertures ménagées centralement dans celui-ci.For this purpose, the central connection device according to the invention of a towel radiator to pipes for the arrival and return of a heat transfer fluid, is of the type comprising two connecting elements which each cooperate in a sealed manner. with an opening disposed in the central portion of a radiator-radiator radiator tube. It is characterized in that the two connecting elements are independent of each other and each cooperate with an opening in the central part of the lower emitter tube, between the two openings formed centrally therein.

Selon une forme de réalisation particulièrement avantageuse, les deux éléments de raccordement sont identiques, ce qui simplifie la fabrication et en réduit le coût, et obturent ainsi chacun de façon étanche le tube émetteur inférieur entre les deux ouvertures ménagées dans celui-ci.According to a particularly advantageous embodiment, the two connecting elements are identical, which simplifies the manufacture and reduces the cost, and thus seal each sealingly the lower emitter tube between the two openings in the latter.

Avantageusement, l'un au moins des éléments de raccordement est constitué, selon l'invention, par une section de tube dont une extrémité est solidaire d'un embout de raccordement à la tuyauterie d'arrivée ou de retour du fluide caloporteur, et dont l'autre extrémité destinée à être introduite dans l'ouverture du tube émetteur inférieur présente une ouverture en biseau. Cette extrémité à ouverture taillée en biseau de la section de tube engage de façon étanche la paroi interne du tube émetteur inférieur, la partie pleine de cette extrémité obturant ce tube émetteur inférieur du côté de sa partie centrale.Advantageously, at least one of the connecting elements is constituted, according to the invention, by a tube section, one end of which is integral with a connection piece to the inlet or return piping of the coolant, and of which the other end intended to be introduced into the opening of the lower emitter tube has a bevel opening. This chamfered aperture end of the tube section sealingly engages the inner wall of the lower emitter tube, the solid portion of this end closing off the lower emitter tube on the side of its central portion.

Selon une caractéristique complémentaire de l'invention, l'embout de raccordement est solidaire d'une portion de tube découpée pour épouser la forme de la partie inférieure du tube émetteur inférieur en entourant de façon étanche l'ouverture ménagée dans ce tube émetteur.According to a complementary feature of the invention, the connecting piece is integral with a portion of cut tube to fit the shape of the lower part of the lower emitter tube sealingly surrounding the opening in said emitter tube.

Ainsi, avec le dispositif de raccordement selon l'invention, la forme des éléments de raccord permet d'assurer une bonne circulation du fluide caloporteur, celui-ci étant guidé afin d'obtenir une bonne irrigation du radiateur.Thus, with the connecting device according to the invention, the shape of the connecting elements ensures a good circulation of the heat transfer fluid, the latter being guided in order to obtain a good irrigation of the radiator.

De plus, la position des raccords sous le tube émetteur inférieur est plus esthétique que dans les dispositions antérieures où les raccords se trouvaient derrière les deux tubes émetteurs inférieurs, et elle présente aussi l'avantage de réduire la profondeur du radiateur et d'offrir une position du robinet de raccordement plus accessible pour l'utilisateur.In addition, the position of the fittings under the lower emitter tube is more aesthetic than in the previous arrangements where the connections were behind the two lower emitting tubes, and it also has the advantage of reducing the depth of the radiator and to offer connection valve position more accessible to the user.

Pour bien faire comprendre le radiateur sèche-serviettes selon la présente invention, on en décrira ci-après une forme de réalisation préférée, en référence aux dessins schématiques annexés dans lesquels :

  • la figure 1 est une vue de face d'un radiateur sèche-serviettes à raccordement central selon l'invention ;
  • la figure 2 est une vue de face, à plus grande échelle, du système de raccordement central du radiateur visible sur la figure 1 ;
  • la figure 3 est une vue en coupe verticale prise selon la ligne III-III visible sur la figure 2 ;et
  • la figure 4 est une vue de dessus du dispositif de raccordement central visible sur la figure 2.
To fully understand the towel radiator according to the present invention, an embodiment will be described hereinafter preferred, with reference to the appended diagrammatic drawings in which:
  • Figure 1 is a front view of a radiator centrally connected towel rail according to the invention;
  • Figure 2 is a front view, on a larger scale, of the central connection system of the radiator visible in Figure 1;
  • FIG. 3 is a vertical sectional view taken along line III-III visible in FIG.
  • FIG. 4 is a view from above of the central connection device visible in FIG. 2.

En référence à la figure 1, on a représenté un radiateur sèche-serviettes du type constitué de plusieurs tubes émetteurs de chaleur parallèles 1, disposés horizontalement dans un plan vertical, et ouverts à chaque extrémité. Chacun des tubes émetteurs 1 est relié, à une extrémité, à un tube collecteur 2 d'arrivée d'un fluide caloporteur, par exemple de l'eau et à l'autre extrémité, à un tube collecteur 3 de retour du fluide caloporteur. Ces tubes collecteurs 2, 3 sont parallèles entre eux et orienté verticalement.Referring to Figure 1, there is shown a towel rail radiator of the type consisting of several parallel heat emitting tubes 1, arranged horizontally in a vertical plane, and open at each end. Each of the emitter tubes 1 is connected at one end to a collection tube 2 for supplying a heat-transfer fluid, for example water, and at the other end, to a collection tube 3 for returning the coolant. These collecting tubes 2, 3 are parallel to each other and oriented vertically.

On a représenté en 4 sur la figure 1 des organes de support solidaires par exemple d'une paroi et qui sont introduits entre deux tubes émetteurs 1 successifs de façon à servir d'appui au radiateur sèche-serviettes et à empêcher celui-ci de s'échapper vers l'avant.FIG. 1 shows support members integral for example with a wall and which are introduced between two successive emitter tubes 1 so as to serve as support for the towel radiator and to prevent it from being escape forward.

Le premier tube émetteur 1, c'est-à-dire le tube émetteur le plus inférieur, est équipé dans sa partie centrale d'un dispositif de raccordement à des tuyauteries (non représentées sur les dessins) d'alimentation en fluide caloporteur et de retour de ce fluide.The first emitter tube 1, that is to say the lowest emitter tube, is equipped in its central part with a connection device to pipes (not shown in the drawings) for supplying heat transfer fluid and back of this fluid.

Comme on le voit plus en détail sur les figures 2 à 4, le dispositif de raccordement est constitué de deux raccords identiques séparés 5, 5' constitués chacun d'une section de tube 6, 6' dont l'extrémité inférieure est soudée à un embout 7, 7' fileté intérieurement pour être raccordé de manière étanche à la tuyauterie d'arrivée (par l'embout 7) et à la tuyauterie de retour (par l'embout 7').As can be seen in more detail in FIGS. 2 to 4, the connecting device consists of two identical identical connectors 5, 5 'each consisting of a tube section 6, 6' whose lower end is welded to a nozzle 7, 7 'internally threaded to be sealingly connected to the inlet pipe (through the nozzle 7) and to the return pipe (by the nozzle 7').

L'autre extrémité 8, 8' de chaque section de tube 6, 6' est coupée en biseau sur une hauteur légèrement inférieure au diamètre intérieur du tube émetteur 1, et est introduite verticalement dans une ouverture de section circulaire 9, 9' ménagée à la partie inférieure du premier tube émetteur 1 et ayant un diamètre très faiblement supérieur au diamètre extérieur de la section de tube 6, 6'. Les ouvertures 9, 9' sont alignées sur le premier tube émetteur 1 et sont écartées l'une de l'autre d'une distance de l'ordre de quelques centimètres.The other end 8, 8 'of each tube section 6, 6' is beveled to a height slightly smaller than the inside diameter of the emitter tube 1, and is introduced vertically into an opening of circular section 9, 9 'provided at the lower part of the first emitter tube 1 and having a very weak diameter greater than the outside diameter of the tube section 6, 6 '. The openings 9, 9 'are aligned on the first emitter tube 1 and are spaced from each other by a distance of the order of a few centimeters.

Chaque section de tube 6, 6' est introduite à force dans l'ouverture 9, 9' de façon que sa partie pleine soit dirigée vers le milieu du tube émetteur 1 et que l'ouverture de son extrémité 8, 8' soit dirigée vers l'extrémité correspondante de ce tube émetteur. Dans cette position, chaque section de tube 6, 6' vient s'appuyer de façon étanche contre la paroi intérieure du tube émetteur 1 et est fixée par soudage dans cette position.Each section of tube 6, 6 'is forced into the opening 9, 9' so that its solid part is directed towards the middle of the emitter tube 1 and that the opening of its end 8, 8 'is directed towards the corresponding end of this emitter tube. In this position, each tube section 6, 6 'is sealingly abut against the inner wall of the emitter tube 1 and is fixed by welding in this position.

On comprend ainsi que la partie pleine de la section de tube 6 obture le premier tube émetteur 1 vers sa partie centrale de sorte que, lorsque l'embout 7 de cette section de tube est vissé sur le conduit d'arrivée de fluide caloporteur, le fluide caloporteur ainsi introduit passe par l'extrémité ouverte 8 de la section de tube et est guidé dans la partie de droite du premier tube émetteur 1 pour atteindre le collecteur 2 et irriguer chacun des autres tubes émetteurs 1 en suivant les chemins désignés par les flèches visibles sur la figure 1.It is thus understood that the solid part of the tube section 6 closes the first emitter tube 1 towards its central part so that, when the end piece 7 of this tube section is screwed onto the heat transfer fluid supply duct, the heat transfer fluid thus introduced passes through the open end 8 of the tube section and is guided in the right portion of the first emitter tube 1 to reach the collector 2 and irrigate each of the other emitter tubes 1 along the paths designated by the arrows visible in Figure 1.

Toujours en référence à la figure 1, l'embout 7' de la section de tube 6' étant vissé sur le conduit de retour du fluide caloporteur, le fluide circulant dans les tubes émetteurs 1 dans le sens des flèches, est recueilli dans le collecteur de retour 3 et débouche dans la partie de gauche du premier tube émetteur 1 pour être guidé par l'extrémité ouverte 8' de la section de tube 6' dans le conduit de retour par lequel il est évacué.Still with reference to FIG. 1, the tip 7 'of the tube section 6' being screwed onto the coolant return duct, the fluid flowing in the emitter tubes 1 in the direction of the arrows is collected in the collector return 3 and opens in the left part of the first emitter tube 1 to be guided by the open end 8 'of the tube section 6' in the return duct through which it is discharged.

On remarquera, comme on le voit en particulier sur la figure 2, que l'embout 7, 7' du raccord 5, 5' se prolonge en direction du tube émetteur 1 par une portion de conduit 10, 10' qui épouse la forme de la partie inférieure du tube émetteur 1, autour de l'ouverture 9, 9' de celui-ci, et est fixée ainsi par soudage au tube à émetteur 1.It will be noted, as can be seen in particular in FIG. 2, that the end piece 7, 7 'of the connection 5, 5' is extended in the direction of the emitter tube 1 by a portion of duct 10, 10 'which is in the shape of the lower part of the emitter tube 1, around the opening 9, 9 'thereof, and is thus fixed by welding to the emitter tube 1.

On comprendra que la description ci-dessus a été donnée à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de la présente invention.It will be understood that the above description has been given by way of example only, without limitation, and that additions or constructive modifications could be made without departing from the scope of the present invention.
