Description

L'invention porte sur l'ensemble que constitue une veilleuse et son allumeur destinée à l'allumage du brûleur d'un appareil de chauffage et/ou de production d'eau chaude sanitaire au gaz et concerne plus précisément un dispositif de positionnement et de centrage dudit ensemble.The invention relates to the assembly constituted by a pilot light and its igniter intended for igniting the burner of a heating and / or domestic hot water production appliance using gas and more specifically relates to a device for positioning and centering said assembly.

Dans les appareils de chauffage au gaz et notamment les chauffe-eau et les chaudières, l'injection du gaz dans les bras du brûleur se fait à partir d'une rampe d'injection qui porte la série d'injecteurs et qui est alimentée en gaz par une tubulure d'admission. Cette rampe est avantageusement disposée horizontalement à l'avant de l'appareil de façon à être accessible et facilement démontable. L'ensemble que constitue le petit tube de veilleuse et l'allumeur qui lui est associé se place sur cette rampe de telle sorte que l'orifice de veilleuse se trouve au-dessus des sorties de gaz des bras de brûleur. L'allumeur est solidaire du tube de veilleuse de telle sorte que son électrode se trouve à proximité de l'orifice de sortie de la veilleuse. Cet ensemble est positionné, de façon habituelle, dans des berceaux qui font partie du corps de la rampe elle-même, et une fois positionné il y est maintenu tout simplement par une petite lame-ressort d'accrochage, comme décrit dans le DE-A 2 000 813. On ôte ou on replace donc très facilement la veilleuse en position sur la rampe.In gas heaters and in particular water heaters and boilers, the gas is injected into the burner arms from an injection rail which carries the series of injectors and which is supplied with gas through an intake manifold. This ramp is advantageously arranged horizontally at the front of the device so as to be accessible and easily removable. The assembly constituted by the small pilot tube and the igniter which is associated with it is placed on this ramp so that the pilot orifice is located above the gas outlets of the burner arms. The igniter is integral with the pilot tube so that its electrode is near the pilot outlet. This assembly is positioned, in the usual way, in cradles which are part of the body of the ramp itself, and once positioned it is simply held there by a small leaf spring hook, as described in DE- A 2 000 813. We therefore remove or replace the pilot very easily in position on the ramp.

Cette facilité de dépose et de repose demande cependant un minimum d'attention car il faut que la veilleuse soit à la bonne hauteur par rapport à la rampe d'injection mais aussi par rapport au plan de sortie des flammes, sinon la flamme de veilleuse ne pourra assurer correctement l'allumage du brûleur. Il faut aussi qu'elle soit orientée parfaitement perpendiculairement à la rampe, sinon la flamme de veilleuse ne lécherait pas la tête du thermocouple de sécurité qui, comme on sait, est généralement fixé au centre de la rampe, à proximité de l'orifice de veilleuse. En outre il apparaît que même si la veilleuse est parfaitement positionnée, le thermocouple lui-même, engagé dans une barrette de support peut prendre avec son montage habituel une inclinaison latérale qui l'écarterait aussi de la flamme de veilleuse.This ease of removal and installation however requires a minimum of attention because the pilot must be at the right height relative to the injection rail but also relative to the flame exit plane, otherwise the pilot flame does not can properly ignite the burner. It must also be oriented perfectly perpendicular to the ramp, otherwise the pilot flame would not lick the head of the safety thermocouple which, as we know, is generally fixed in the center of the ramp, near the orifice of night light. In addition, it appears that even if the pilot is perfectly positioned, the thermocouple itself, engaged in a support bar can take with its usual mounting a lateral inclination which would also separate it from the pilot flame.

Les difficultés de positionnement tiennent au fait que le ou les berceaux contre lesquels vient s'appliquer le tube de veilleuse n'empêchent pas la rotation de celui-ci et ne fixent pas de façon rigoureuse son positionnement correct en hauteur.The positioning difficulties are due to the fact that the cradle (s) against which the pilot light tube is applied do not prevent the rotation of the latter and do not rigorously fix its correct positioning in height.

L'invention apporte donc une solution à ce problème en ce qu'elle permet, par une modification simple du support de veilleuse de faire en sorte que le positionnement et le centrage de l'ensemble veilleuse et allumeur soit toujours correctement assuré même par un utilisateur non attentionné.The invention therefore provides a solution to this problem in that it allows, by a simple modification of the pilot light support, to ensure that the positioning and centering of the pilot and igniter assembly is always correctly ensured even by a user. not attentive.

L'invention a donc pour objet un dispositif comprenant un ensemble veilleuse-allumeur, un thermocouple supporté par un étrier et un dispositif de positionnement et de centrage dudit ensemble disposant de berceaux formés d'échancrures constituant des butées d'appui aptes à recevoir le tube de veilleuse, ledit tube portant un collet permettant son positionnement, dispositif selon lequel au moins une butée d'appui du berceau comporte des parties usinées ou venant au moulage, dans lesquelles se loge le collet de positionnement dudit tube de veilleuse, au moins une nervure étant rapportée sur le berceau et interdisant la pénétration dudit collet dans l'espace intermédiaire entre les échancrures des berceaux, et en ce qu'un moyen complémentaire constitué d'une fourche de guidage sensiblement parallèle à l'étrier du thermocouple, garantit le positionnement correct du thermocouple.The subject of the invention is therefore a device comprising a pilot-igniter assembly, a thermocouple supported by a stirrup and a positioning and centering device of said assembly having cradles formed by notches constituting support stops capable of receiving the tube pilot light, said tube carrying a collar allowing its positioning, device according to which at least one support stop for the cradle has machined or molded parts, in which the positioning collar of said pilot tube is housed, at least one rib being attached to the cradle and preventing the penetration of said collar into the intermediate space between the notches of the cradles, and in that an additional means consisting of a guide fork substantially parallel to the caliper of the thermocouple, guarantees correct positioning thermocouple.

Selon une caractéristique particulère de l'invention, la butée d'appui est creusée d'une rainure horizontale comportant deux parties usinées rectilignes et parallèles formant les côtés des échancrures constituant le berceau, et une partie arrondie formant le fond, et parallèlement, le collet de positionnement du tube de veilleuse présente des côtés latéraux opposés rectilignes et une partie avant arrondie.According to a particular characteristic of the invention, the support stop is hollowed out with a horizontal groove comprising two rectilinear and parallel machined parts forming the sides of the notches constituting the cradle, and a rounded part forming the bottom, and in parallel, the collar position of the pilot tube has opposite straight lateral sides and a rounded front part.

Selon une autre caractéristique de l'invention la nervure s'étend horizontalement sur un des côtés des échancrures entre la butée d'appui et un méplat supérieur servant de point d'appui supérieur pour le tube de veilleuse.According to another characteristic of the invention, the rib extends horizontally on one of the sides of the notches between the support stop and an upper flat serving as an upper support point for the pilot tube.

Les avantages et dispositions particulières de l'invention ressortiront de la description suivante d'une rampe d'injection et de l'ensemble veilleuse et allumeur, dans laquelle les dessins annexés représentent :The advantages and specific provisions of the invention will emerge from the following description of an injection manifold and of the pilot and igniter assembly, in which the attached drawings represent:

Figure 1 une vue générale en coupe transversale de la rampe et de l'ensemble veilleuse-allumeur, monté sur elle.Figure 1 a general cross-sectional view of the ramp and the pilot-igniter assembly, mounted on it.

Figure 2 une vue partielle en coupe transversale et figure 3 une vue en perspective des berceaux qui supportent l'ensemble.Figure 2 a partial view in cross section and Figure 3 a perspective view of the cradles which support the assembly.

Figure 4 une vue en coupe d'une échancrure profilée et figure 5 une vue en coupe du collet du tube de veilleuse.Figure 4 a sectional view of a profiled notch and Figure 5 a sectional view of the pilot tube collar.

La figure 1 montre l'ensemble constitué par un tube de veilleuse 2 et son allumeur 3 en appui contre une rampe d'injection - désignée dans son ensemble par la référence 1 - qui distribue du gaz provenant de la tubulure 20 vers des rampes de brûleur 4 par l'intermédiaire d'injecteurs 5. Un thermocouple 6 est engagé dans un étrier support 7 de telle sorte que sa tête 8 se trouve au niveau de l'électrode de l'allumeur, sensiblement au-dessus de l'orifice de sortie du tube de veilleuse 2. La veilleuse 2 est une section de tube de forme coudée dont l'orifice d'entrée, à la partie inférieure est en communication avec l'atmosphère pour l'admission d'air primaire. Un petit conduit d'arrivée de gaz 9 débouchant au-dessus et à proximité de cet orifice d'entrée du tube 2 est également maintenu contre une potence de positionnement 18 faisant partie de la rampe d'injection 1.Figure 1 shows the assembly consisting of a pilot tube 2 and its igniter 3 in abutment against an injection rail - generally designated by the reference 1 - which distributes gas from the pipe 20 to burner rails 4 via injectors 5. A thermocouple 6 is engaged in a support bracket 7 so that its head 8 is at the level of the igniter electrode, substantially above the outlet orifice of the pilot light tube 2. The pilot light 2 is a section of tube of bent shape whose inlet orifice, at the bottom is in communication with the atmosphere for the admission of primary air. A small gas inlet pipe 9 opening above and near this inlet opening of the tube 2 is also held against a positioning bracket 18 forming part of the injection manifold 1.

L'ensemble tube de veilleuse et allumeur vient donc en appui contre un berceau 10 solidaire de la rampe d'injection 1. Ce berceau mieux visible sur les figures 2, et 3 est constitué d'un méplat 11 servant de point d'appui supérieur pour le tube de veilleuse 2, et se terminant par une échancrure 12 arrondie ou non, dans laquelle vient s'appliquer la partie courante du tube 2, et il est constitué aussi d'une butée d'appui 13, sensiblement au niveau de la rampe d'injection, elle-même pourvue d'une échancrure arrondie 14. Cette butée est d'une épaisseur suffisante pour être creusée en son milieu par une rainure horizontale 15, plus profonde que l'échancrure 14, qu'elle sépare en deux becs distincts. Cette rainure 15 a un profil particulier, représenté à la figure 4, qui comporte essentiellement deux parties usinées rectilignes parallèles 16 formant les côtés du bec et une partie arrondie d'appui 17 formant le fond. Dans cette rainure se loge un collet de positionnement 21, solidaire du tube de veilleuse 2, collet dont les côtés latéraux opposés 22 sont également rectilignes et la partie avant arrondie (voir figure 5). On comprend que le collet 21 est destiné à se placer dans la rainure 15 entre les deux becs de l'échancrure 14, tandis que le tube de veilleuse lui-même s'appuie contre le méplat supérieur 11. Ainsi engagée entre les deux parties de l'échancrure 14, le collet immobilise et positionne en hauteur le tube de veilleuse 2. Les deux côtés 22 du collet 21 viennent alors en appui contre les parties rectilignes 16 de la rainure 15. De ce fait le tube 2 est parfaitement immobilisé en rotation et la tête de veilleuse se trouve centrée et correctement orientée vis à vis des rampes de brûleur.The pilot and igniter tube assembly therefore comes to bear against a cradle 10 secured to the injection rail 1. This cradle is better visible in FIGS. 2, and 3 consists of a flat 11 serving as an upper support point. for the pilot light tube 2, and ending with a round or not rounded notch 12, in which the current part of the tube 2 is applied, and it also consists of a support stop 13, substantially at the level of the injection rail, itself provided with a rounded notch 14. This stop is of sufficient thickness to be hollowed out in the middle by a horizontal groove 15, deeper than the notch 14, which it separates in two separate beaks. This groove 15 has a particular profile, shown in Figure 4, which essentially comprises two parallel rectilinear machined parts 16 forming the sides of the spout and a rounded support part 17 forming the bottom. In this groove is housed a positioning collar 21, integral with the pilot tube 2, collar whose opposite lateral sides 22 are also rectilinear and the front part rounded (see FIG. 5). It is understood that the collar 21 is intended to be placed in the groove 15 between the two nozzles of the notch 14, while the pilot tube itself is pressed against the upper flat 11. Thus engaged between the two parts of the notch 14, the collar immobilizes and positions the pilot tube 2 in height. The two sides 22 of the collar 21 then come to bear against the straight parts 16 of the groove 15. Therefore the tube 2 is perfectly immobilized in rotation and the pilot head is centered and correctly oriented with respect to the burner rails.

Si on ne prête pas attention à bien placer le tube de veilleuse de telle façon que le collet 21 du tube 2 dans la rainure 15, entre les becs de la butée d'appui, c'est que le tube 2 est présenté sur le berceau trop bas ou trop haut. S'il est trop bas, le collet venant en face de l'espace qui sépare la butée d'appui 13 de la potence 18, l'extrémité inférieure du tube 2 bute contre le conduit 9 et interdit le positionnement correct du tube. S'il est présenté trop haut, le collet 21 venant en face de l'espace qui sépare la butée d'appui 13 du méplat supérieur 11, vient en butée contre une nervure horizontale 19 qui s'étend latéralement sur un des côtés des échancrures 12 et 14, justement entre cette butée d'appui et le méplat supérieur. La nervure 19 interdit donc la pénétration du collet dans cet espace intermédiaire.If you do not pay attention to correctly place the pilot tube so that the collar 21 of the tube 2 in the groove 15, between the spouts of the support stop, is that the tube 2 is presented on the cradle too low or too high. If it is too low, the collar coming opposite the space which separates the support stop 13 from the bracket 18, the end bottom of the tube 2 abuts against the conduit 9 and prevents the correct positioning of the tube. If it is presented too high, the collar 21 coming in front of the space which separates the support stop 13 from the upper flat 11, comes into abutment against a horizontal rib 19 which extends laterally on one of the sides of the notches 12 and 14, precisely between this support stop and the upper flat. The rib 19 therefore prohibits the penetration of the collar in this intermediate space.

Le profil du collet et de la rainure support ainsi que la présence de ladite nervure participent donc ensemble au positionnement parfait de l'ensemble tube-veilleuse et allumeur sur la rampe d'injection de gaz.The profile of the collar and the support groove as well as the presence of said rib therefore participate together in the perfect positioning of the tube-pilot and igniter assembly on the gas injection rail.

En se reportant à la figure 1, on voit que le thermocouple 6 est engagé dans l'étrier 7. Pour que sa tête 8 ne puisse s'incliner latéralement, c'est-à-dire s'éloigner d'un côté ou de l'autre, de l'orifice de sortie de flamme de veilleuse, il est prévue une fourche de guidage 23 sensiblement parallèle à l'étrier, et ouverte vers le haut, qui fait partie de la barrette d'assemblage du tube de veilleuse 2 et de l'allumeur 3. Ainsi quand on met en place cet ensemble, de la façon indiquée plus haut, la fourche se trouve automatiquement parfaitement positionnée, et réajuste ou maintient également la tête de thermocouple dans une position tout à fait correcte.Referring to Figure 1, we see that the thermocouple 6 is engaged in the bracket 7. So that its head 8 can not tilt laterally, that is to say move away from one side or the other, from the pilot flame outlet orifice, there is provided a guide fork 23 substantially parallel to the stirrup, and open upwards, which is part of the assembly bar of the pilot tube 2 and the igniter 3. Thus when this assembly is put in place, as indicated above, the fork is automatically perfectly positioned, and also readjusts or maintains the thermocouple head in a completely correct position.

L'invention n'est pas limitée à l'exemple de réalisation décrit. C'est ainsi qu'à la place d'un tube de veilleuse 2 de section circulaire avec des parties usinées rectilignes, on pourrait utiliser un tube de section carrée au moins dans la zone des berceaux support, ce qui n'exclurait pas que le tube possède un collet de positionnement en hauteur. Les parties usinées 15,16 font donc partie de cette section carrée du tube de veilleuse.The invention is not limited to the embodiment described. Thus, instead of a pilot tube 2 of circular section with rectilinear machined parts, a tube of square section could be used at least in the area of the support cradles, which would not exclude that the tube has a height positioning collar. The machined parts 15, 16 therefore form part of this square section of the pilot tube.
