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 les 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 said assembly.

Le but de l'invention est de réduire ce coût et cette complexité en réalisant 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 combined chassis, that is to say incorporating a substantial number of elements, parts or parts of organs, hitherto produced separately and then added on a support structure.

A cet effet, l'invention a pour objet un châssis pour chaudière, notamment murale, pour le chauffage et l'eau sanitaire, du type comportant un corps de chauffe associé à un échangeur de chaleur air/eau relié, d'une part, à un orifice de retour d'eau de chauffage, par l'intermédiaire d'une pompe de circulation et d'un clapet inverseur, et, d'autre part, à un orifice de départ d'eau de chauffage, par l'intermédiaire d'une enceinte reliée par un conduit audit clapet et dans laquelle est plongé un échangeur de chaleur eau/eau de fourniture d'eau chaude sanitaire, ledit châssis étant caractérisé en ce qu'il est constitué par une plaque monobloc de matière moulée dans laquelle sont conformés, par moulage, le corps dudit clapet inverseur, le corps de ladite pompe de circulation, un logement constituant ladite enceinte de réception de l'échangeur eau/eau, les orifices d'entrée et sortie du circuit de circulation d'eau de chauffage, les conduits reliant les divers éléments ci-dessus, ainsi qu'au moins une partie des moyens de fixation des pièces rapportées sur le châssis et de ce dernier sur son support.To this end, the subject of the invention is a chassis for a boiler, in particular a wall-mounted one, for heating and sanitary water, of the type comprising a heating body associated with an air / water heat exchanger connected on the one hand, at an orifice return of heating water, via a circulation pump and a reversing valve, and, on the other hand, to a heating water outlet orifice, via a enclosure connected by a conduit to said valve and in which is immersed a water / water heat exchanger for supplying domestic hot water, said chassis being characterized in that it is constituted by a monobloc plate of molded material in which are shaped, by molding, the body of said reversing valve, the body of said circulation pump, a housing constituting said enclosure for receiving the water / water exchanger, the inlet and outlet orifices of the heating water circulation circuit, the conduits connecting the various elements above, as well as at least a part of the means for fixing the parts added to the chassis and the latter on its support.

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.Such a frame incorporating a large number of parts of the boiler facilitates the mounting of the latter, makes it possible to standardize the manufacture by reducing the number of parts to be manufactured elsewhere and to achieve savings in operating the boiler due to the thermal flywheel constituted. by the mass of the chassis.

Les figures 1 et 2 sont deux schémas illustrant les deux modes de fonctionnement d'une chaudière murale équipée d'un châssis selon l'invention, 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 modes of operation of a wall-mounted boiler equipped with a frame according to the invention, 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 the orifice 3 to the orifice 6, via the 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.

L'objet de l'invention est un châssis agencé de façon à intégrer une partie substantielle des circuits d'eau symbolisés sur les figures 1 et 2.The object of the invention is 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 the said wall there is in fact 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'un 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 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.

Enfin, l'invention n'est pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes notamment en ce qui concerne les formes, dimensions et agencements des parties des circuits de fluides intégrées dans le châssis monobloc en matière moulée.Finally, the invention is not limited to the embodiment shown and described above, but on the contrary covers all variants thereof, in particular as regards the shapes, dimensions and arrangements of the parts of the fluid circuits integrated in the one-piece chassis. in molded material.
