Description

La présente invention a trait aux chaudières, en particulier murales, destinées à la fourniture à la fois de l'eau chaude sanitaire en été comme en hiver et du chauffage.The present invention relates to boilers, in particular wall-hung boilers, intended for the supply of both domestic hot water in summer and winter and heating.

Plus précisément l'invention s'applique aux chaudières du type comprenant un corps de chauffe unique portant à température de l'eau envoyée, par l'intermédiaire d'un clapet d'inversion, soit dans le circuit externe des radiateurs de chauffage, soit dans un circuit fermé interne à la chaudière dans lequel est plongé un serpentin d'un circuit d'alimentation en eau chaude sanitaire.More specifically, the invention applies to boilers of the type comprising a single heating body carrying the temperature of the water sent, by means of a reversing valve, either in the external circuit of the heating radiators, or in a closed circuit internal to the boiler in which a coil of a domestic hot water supply circuit is immersed.

Les chaudières murales actuelles de ce type comporte un châssis qui est une simple structure de support et de montage sur laquelle sont rapportés et fixés tous tes éléments des divers sous-ensembles et leurs liaisons.Current wall-mounted boilers of this type comprise a frame which is a simple support and mounting structure on which are attached and fixed all the elements of the various sub-assemblies and their connections.

L'ensemble est ainsi constitué d'un nombre relativement important de pièces distinctes ce qui complique et rend plus coûteux la réalisation et le montage dudit ensemble.The assembly thus consists of a relatively large number of separate parts, which complicates and makes it more expensive to produce and assemble the assembly.

Il est connu des documents EP-A-0 244 915 et EP-A-0 000 584 de réaliser le châssis d'une chaudière à l'aide de deux tôles assemblées, ce qui ne constitue absolument pas un volant thermique ni un châssis monobloc supportant tous les organes et accessoires de la chaudière.
Par ailleurs, le document EP-A-0 236 235 comprend certes une embase monobloc en matière moulée, conformée de façon à constituer une partie des enveloppes d'une partie des sous-ensembles et des conduits de liaison de la chaudière.
Néanmoins, dans la chaudière selon EP-A-0 236 235, tous les éléments générant les eaux chaudes et leurs accessoires ne sont pas portés par la seule embase. Au contraire, la chaudière selon EP-A-0 236 235 comprend divers éléments distincts comprenant chacun une partie des organes et accessoires de la chaudière, ce qui augmente la complexité et le coût de fabrication, de stockage et de montage de la structure porteuse de la chaudière.It is known from documents EP-A-0 244 915 and EP-A-0 000 584 to produce the chassis of a boiler using two assembled sheets, which in no way constitutes a thermal flywheel or a one-piece chassis supporting all parts and accessories of the boiler.
Furthermore, document EP-A-0 236 235 certainly includes a one-piece base made of molded material, shaped so as to constitute a part of the envelopes of a part of the subassemblies and connecting ducts of the boiler.
However, in the boiler according to EP-A-0 236 235, all the elements generating the hot water and their accessories are not carried by the only base. On the contrary, the boiler according to EP-A-0 236 235 comprises various distinct elements each comprising a part of the organs and accessories of the boiler, which increases the complexity and the cost of manufacturing, storage and assembly of the load-bearing structure. Boiler.

Le but de l'invention est de réduire ce coût et cette complexité en réalisant une chaudière comportant un châssis combiné, c'est-à-dire incorporant un nombre substantiel d'éléments, pièces ou parties d'organes, jusque là réalisés à part et rapportés ensuite sur une structure support.The object of the invention is to reduce this cost and this complexity by producing a boiler comprising a combined chassis, that is to say incorporating a substantial number of elements, parts or parts of organs, hitherto produced separately and then reported on a support structure.

A cet effet, l'invention a pour objet une chaudière selon la revendication 1To this end, the invention relates to a boiler according to claim 1

Une chaudière comportant un tel châssis intégrant un nombre important de pièces de la chaudière facilite le montage de cette dernière, permet de standardiser la fabrication en réduisant le nombre de pièces à fabriquer par ailleurs et de réaliser des économies de fonctionnement de la chaudière du fait du volant thermique constitué par la masse du châssis.A boiler comprising such a frame incorporating a large number of parts of the boiler facilitates the assembly of the latter, makes it possible to standardize the manufacture by reducing the number of parts to be produced elsewhere and to make savings in operating the boiler due to the thermal flywheel formed by the mass of the chassis.

Les figures 1 et 2 sont deux schémas illustrant les deux modes de fonctionnement d'une chaudière murale selon l'invention équipée d'un châssis, symbolisé par un rectangle 1, à l'intérieur duquel sont esquissés les deux circuits d'eau d'une telle chaudière.Figures 1 and 2 are two diagrams illustrating the two operating modes of a wall-mounted boiler according to the invention equipped with a frame, symbolized by a rectangle 1, inside which are sketched the two water circuits of such a boiler.

Le principe et le fonctionnement de ce type de chaudière, destiné au chauffage l'hiver et à la fourniture d'eau chaude sanitaire en hiver et en été sont bien connus.The principle and operation of this type of boiler, intended for heating in winter and for the supply of domestic hot water in winter and summer are well known.

Un échangeur de chaleur air/eau 2, disposé au-dessus d'un brûleur (non représenté) est relié, d'une part, à un orifice 3 de retour d'eau de chauffage, via une pompe 4, et un clapet inverseur 5, et, d'autre part, à un orifice 6 de départ d'eau chaude de chauffage, via un conduit 7 communiquant avec une enceinte 8 elle-même reliée au clapet 5 et dans laquelle est plongé un échangeur de chaleur eau/eau 9 présentant deux orifices 10 et 11 d'arrivée d'eau froide et de départ d'eau chaude respectivement.An air / water heat exchanger 2, disposed above a burner (not shown) is connected, on the one hand, to an orifice 3 for the return of heating water, via a pump 4, and a reversing valve. 5, and, on the other hand, to an orifice 6 for the departure of hot water for heating, via a conduit 7 communicating with an enclosure 8 itself connected to the valve 5 and in which is immersed a water / water heat exchanger 9 having two orifices 10 and 11 for cold water inlet and hot water outlet respectively.

La figure 1 illustre le fonctionnement en chauffage hiver de la chaudière, la circulation de l'eau s'effectuant suivant les flèches depuis l'orifice 3 jusqu'à l'orifice 6, via les organes 5,4,2 et 7. L'enceinte 8 forme cul-de-sac puisqu'isolée par le clapet 5.FIG. 1 illustrates the operation in winter heating of the boiler, the circulation of the water taking place according to the arrows from port 3 to port 6, via members 5, 4, 2 and 7. L enclosure 8 forms a dead end since isolated by the valve 5.

Dans le fonctionnement en eau chaude hiver et été (figure 2) le clapet 5 est dans son autre position faisant circuler l'eau suivant une boucle fermée, illustrée par les flèches et reliant les organes 2,7,8,5 et 4, la circulation d'eau (de chauffage) par les orifices 3 et 6 étant arrêtée l'été, mais établie l'hiver.In winter and summer hot water operation (Figure 2) the valve 5 is in its other position circulating the water in a closed loop, illustrated by the arrows and connecting the members 2,7,8,5 and 4, the circulation of water (heating) through ports 3 and 6 being stopped in summer, but established in winter.

La chaudière selon l'invention comprend un châssis agencé de façon à intégrer une partie substantielle des circuits d'eau symbolisés sur les figures 1 et 2.The boiler according to the invention comprises a chassis arranged so as to integrate a substantial part of the water circuits symbolized in FIGS. 1 and 2.

Les figures 3 à 8 représentent un mode de réalisation d'un châssis conforme à l'invention.Figures 3 to 8 show an embodiment of a chassis according to the invention.

Un tel châssis est constitué d'une plaque monobloc 1 de matière moulée, par exemple de la fonte, de forme générale rectangulaire et conformée, par moulage, de façon à constituer elle-même tout ou partie des éléments constitutifs des deux circuits d'eau illustrés en figures 1 et 2, éléments qui, jusqu'à présent, étaient constitués par des pièces indépendantes et distinctes du châssis traditionnel des chaudières murales de ce type.Such a frame consists of a one-piece plate 1 of molded material, for example cast iron, of generally rectangular shape and shaped, by molding, so as to itself constitute all or part of the constituent elements of the two water circuits illustrated in Figures 1 and 2, elements which, until now, consisted of parts independent and distinct from the traditional chassis of wall-hung boilers of this type.

C'est ainsi que la paroi de ladite plaque de matière moulée 1 est conformée en 5′ de façon à constituer le corps du clapet inverseur 5 avec une chambre 12 communiquant, d'une part, avec l'orifice 3 de retour d'eau de chauffage, via un conduit coudé 13, et, d'autre part, avec un conduit 14 communiquant avec l'orifice d'entrée d'un corps de pompe 4′, lui-même communiquant avec un conduit 15.Thus the wall of said molded material plate 1 is shaped in 5 ′ so as to constitute the body of the reversing valve 5 with a chamber 12 communicating, on the one hand, with the orifice 3 of water return. heating, via an elbow conduit 13, and, on the other hand, with a conduit 14 communicating with the inlet orifice of a pump body 4 ′, itself communicating with a conduit 15.

Les éléments 4′,5′,12,13,14 et 15 sont disposés d'un côté du plan général de la plaque 1 (figure 8). Sur l'autre côté de la plaque débouchent l'orifice 16 d'insertion de la pièce mobile de commande du clapet inverseur 5, l'orifice 17 d'insertion de la turbine de la pompe 4 et l'orifice 18 du conduit 15.The elements 4 ′, 5 ′, 12, 13, 14 and 15 are arranged on one side of the general plane of the plate 1 (FIG. 8). On the other side of the plate open the orifice 16 for insertion of the movable part for controlling the reversing valve 5, the orifice 17 for insertion of the turbine of the pump 4 and the orifice 18 for the conduit 15.

Cet orifice est taraudé pour recevoir un raccord de connexion à l'échangeur 2 (non représenté sur les figures 3 à 8).This orifice is tapped to receive a connection connection to the exchanger 2 (not shown in Figures 3 to 8).

Quant à l'orifice 3, il débouche sur la tranche inférieure de la plaque 1 et est également taraudé pour recevoir un raccord de connexion à la tubulure du système de chauffage.As for the orifice 3, it opens onto the lower edge of the plate 1 and is also tapped to receive a connection fitting to the manifold of the heating system.

Le corps de pompe 4′ comporte bien entendu des oreilles 19 de fixation de la turbine et de son moteur électrique d'entraînement.The pump body 4 ′ obviously includes ears 19 for fixing the turbine and its electric drive motor.

De même, la plaque 1 est conformée pour constituer un conduit 20 reliant l'orifice 6 de départ d'eau de chauffage à un orifice 21 de raccordement à l'autre extrémité de l'échangeur 2, taraudé comme l'orifice 18 et débouchant sur le même côté de la plaque.Likewise, the plate 1 is shaped to constitute a conduit 20 connecting the orifice 6 for the start of heating water to an orifice 21 for connection to the other end of the exchanger 2, tapped like the orifice 18 and opening on the same side of the plate.

Le conduit 20 communique également, par un conduit 22, avec un orifice 23 de dégazage accessible sur la tranche supérieure de la plaque 1 et taraudé pour recevoir un clapet de dégazage (non représenté).The conduit 20 also communicates, via a conduit 22, with a degassing orifice 23 accessible on the upper edge of the plate 1 and tapped to receive a degassing valve (not shown).

Le conduit 20 communique, enfin, avec l'extrémité supérieure d'une chambre cylindrique 24 constituant l'enceinte 8 dans laquelle sera immergé le serpentin de l'échangeur 9. La chambre 24 est, à son extrémité inférieure, ouverte et munie d'une collerette 25 de fixation d'un flasque (non représenté) d'obturation et de support dudit échangeur 9 avec ses orifices de raccordement 10 et 11.The conduit 20 communicates, finally, with the upper end of a cylindrical chamber 24 constituting the enclosure 8 in which will be immersed the coil of the exchanger 9. The chamber 24 is, at its lower end, open and provided with a flange 25 for fixing a flange (not shown) closing and supporting said exchanger 9 with its connection orifices 10 and 11.

A sa partie inférieure, la chambre 24 communique (figure 6) par un conduit 26 avec une seconde chambre 27 du corps de clapet 5′.At its lower part, the chamber 24 communicates (FIG. 6) by a conduit 26 with a second chamber 27 of the valve body 5 ′.

Pour des raisons de clarté on n'a pas représenté sur les figures 4 et 5 les parties 5′ et 26.For reasons of clarity, parts 5 ′ and 26 have not been shown in FIGS. 4 and 5.

Sur tout son pourtour la plaque 1 comporte une aile en retour 28 de rigidification, dans laquelle sont ménagés les orifices taraudés de raccordement 3,6 et 23.Around its entire periphery, the plate 1 comprises a return wing 28 for stiffening, in which the threaded connection orifices 3, 6 and 23 are formed.

La face où débouchent les orifices 18 et 21 est opposée à la paroi murale de fixation de la chaudière et reçoit les éléments rapportés, à savoir, le clapet 5, la pompe 4 et son moteur, l'échangeur 2 et son brûleur dont l'ensemble est positionné et fixé à l'aide de deux nervures horizontales 29 (figure 3) et de trous appropriés 30.The face where the orifices 18 and 21 open is opposite the wall for fixing the boiler and receives the added elements, namely, the valve 5, the pump 4 and its motor, the exchanger 2 and its burner, the assembly is positioned and fixed using two horizontal ribs 29 (FIG. 3) and appropriate holes 30.

D'autres trous (31) en partie haute de la plaque 1 permettent un éventuel montage soit d'un coupe-tirage (non représenté) soit d'un système pour chaudière étanche dite à ventouse (également non représenté).Other holes (31) in the upper part of the plate 1 allow possible mounting either of a draft hood (not shown) or of a sealed boiler system called a suction cup (also not shown).

D'autres trous sont prévus dans la plaque pour la fixation d'un capotage (non représenté) enveloppant la façade avant de la chaudière mais aussi la partie arrière (entre la plaque 1 et la paroi de fixation de la chaudière).Other holes are provided in the plate for fixing a cover (not shown) enveloping the front face of the boiler but also the rear part (between plate 1 and the fixing wall of the boiler).

Entre la plaque et ladite paroi existe en effet un intervalle nécessaire à la chambre 24 ainsi qu'au vase d'expansion équipant toute chaudière et qui sera disposé derrière la plaque 1 au-dessus de la chambre 24.Between the plate and said wall there is indeed a necessary gap for the chamber 24 as well as for the expansion vessel fitted to any boiler and which will be placed behind the plate 1 above the chamber 24.

On peut bien entendu prévoir une aile 28 de hauteur suffisante pour masquer ledit intervalle entre plaque et mur.It is of course possible to provide a wing 28 of sufficient height to mask said gap between plate and wall.

L'ensemble des parties référencées 12 à 32 est bien entendu réalisé en une seule opération de moulage avec des usinages en reprise aux endroits nécessitant un ajustement relativement précis.All of the parts referenced 12 to 32 are of course produced in a single molding operation with machining in recovery at the places requiring a relatively precise adjustment.

La plaque 1 est fixée au mur de préférence par l'intermédiaire d'une plaque-support en tôle scellée dans le mur et fixée à la plaque 1 par l'intermédiaire de trous appropriés 32 en partie supérieure de la plaque, dans l'aile 28 (figures 4,7).The plate 1 is fixed to the wall preferably by means of a support plate made of sheet metal sealed in the wall and fixed to the plate 1 by means of suitable holes 32 in the upper part of the plate, in the wing. 28 (Figures 4.7).

Il est évident qu'une chaudière comportant tel châssis permet de réduire très substantiellement le nombre de pièces rapportées sur la plaque 1 pour constituer la chaudière. En effet, auparavant, les fonctions realisées par les parties moulées de la plaque référencées 12 à 27 étaient obtenues par autant de pièces distinctes rapportées sur la structure support de la chaudière.It is obvious that a boiler comprising such a chassis makes it possible to very substantially reduce the number of parts added to the plate 1 to constitute the boiler. Indeed, previously, the functions performed by the molded parts of the plate referenced 12 to 27 were obtained by as many separate parts attached to the support structure of the boiler.

L'invention permet donc en premier lieu de réduire le nombre de pièces différentes à réaliser séparément, stocker et assembler pour fabriquer une chaudière murale.The invention therefore makes it possible first of all to reduce the number of different parts to be produced separately, to store and to assemble to manufacture a wall-mounted boiler.

La fabrication est ainsi plus facile à gérer grâce à une meilleure standardisation. Elle est moins coûteuse également en temps et en main d'oeuvre.Manufacturing is therefore easier to manage thanks to better standardization. It is also less costly in terms of time and labor.

Un tel châssis facilite par ailleurs le service après-vente car tous les éléments rapportés le sont en façade de la plaque et aisément accessibles après dépose du capotage protecteur.Such a chassis also facilitates after-sales service because all the added elements are on the front of the plate and easily accessible after removing the protective cover.

Il permet, en outre, des économies de fonctionnement grâce au volant thermique constitué par la masse du châssis. L'échangeur, notamment l'hiver, permet en particulier de relever le niveau de la température de l'eau de puisage.It also allows operating savings thanks to the thermal flywheel formed by the mass of the chassis. The exchanger, especially in winter, makes it possible in particular to raise the level of the temperature of the drawing water.

Une telle structure intégrée présente aussi un avantage phonique du fait que la pompe est noyée dans le bloc de matière moulée en sorte qu'il ne se produit ni vibrations ni résonances contrairement à la plupart des chaudières murales connues.Such an integrated structure also has a phonic advantage because the pump is embedded in the block of molded material so that neither vibrations nor resonances occur, unlike most known wall-mounted boilers.

Par ailleurs, l'intégration dans le châssis des conduits 13,14,15,20,22,26 réduit très sensiblement le nombre des raccords et donc le risque de fuite.Furthermore, the integration into the chassis of the pipes 13,14,15,20,22,26 very significantly reduces the number of fittings and therefore the risk of leakage.
