Description

L'invention se rapporte aux chaudières à tirage forcé et concerne plus précisément un assemblage permettant d'assurer l'étanchéité de l'appareil directement à l'aide des panneaux plats qui forment son habillage extérieur.The invention relates to forced draft boilers and more specifically relates to an assembly making it possible to seal the appliance directly using the flat panels which form its external covering.

Dans les chauffe-bains ou chaudières étanches à gaz on sait que la chambre de combustion, reliée à l'atmosphère extérieure du local est isolée de façon étanche aux gaz par rapport à ce local. Dans certains cas une chambre intermédiaire servant à l'admission d'air frais enveloppe de façon étanche la chambre de combustion, cette chambre étant elle-même incorporée dans une enveloppe extérieure à l'appareil qui coiffe l'ensemble des mécanismes la composant. Dans certains types d'appareils, puisque l'étanchéité n'est nécessaire qu'au niveau du brûleur et de la chambre de combustion, l'enveloppe n'est prévue étanche que sur une carcasse supérieure à leur niveau, tandis que le reste des mécanismes est disposé dans une carcasse inférieure non étanche et donc plus facilement accessible (FR-E-79 668). Quoi qu'il en soit et pour des raisons évidentes d'économie, on cherche maintenant à réaliser des capots extérieurs qui constituent à la fois l'enveloppe d'habillage et la chambre étanche qui coiffe le circuit de combustion, ce capot devant évidemment s'adapter rigoureusement au profil des bords de l'appareil ou de la carcasse supérieure et assurer ainsi une étanchéité parfaite.In gas-tight bath heaters or boilers it is known that the combustion chamber, connected to the outside atmosphere of the room is insulated in a gas-tight manner with respect to this room. In certain cases an intermediate chamber serving for the admission of fresh air tightly envelops the combustion chamber, this chamber itself being incorporated in an envelope external to the appliance which covers all of the mechanisms making it up. In certain types of appliance, since sealing is only necessary at the level of the burner and the combustion chamber, the casing is only provided sealing on a carcass above their level, while the rest of the mechanisms is arranged in a non-sealed lower carcass and therefore more easily accessible (FR-E-79 668). Anyway and for obvious reasons of economy, we are now trying to make external covers which constitute both the covering casing and the sealed chamber which covers the combustion circuit, this cover obviously in front of '' rigorously adapt to the profile of the edges of the device or of the upper carcass and thus ensure a perfect seal.

A cet effet, on connaît plusieurs types de capots ayant la forme de coquilles qui s'appliquent contre des joints disposés dans des gouttières prévues sur tout le pourtour de l'appareil, ou qui s'adaptent à d'autres coquilles réceptrices.For this purpose, there are known several types of covers in the form of shells which are applied against seals arranged in gutters provided around the entire periphery of the device, or which adapt to other receiving shells.

Ceci n'est pas sans poser de problèmes, d'une part en fabrication car le capot lui-même ainsi que le support sur lequel il doit d'adapter doivent être parfaitement aux cotes, d'autre part au montage car du fait de sa conception rigide, l'écrasement régulier et suffisant des joints nécessaires à une bonne étanchéité nécessite des attaches de fixation au support, nombreuses et particulièrement précises, tenant compte des probables déformations du capot et de l'usure des joints dans le temps.This is not without problems, on the one hand in manufacturing because the cover itself as well as the support on which it must adapt must be perfectly dimensioned, on the other hand during assembly because of its rigid design, regular and sufficient crushing of the seals necessary for a good seal requires fastening clips to the support, numerous and particularly precise, taking into account the probable deformations of the cover and the wear of the seals over time.

L'invention propose une solution qui évite ces inconvénients en ce que l'étanchéité n'est pas assurée par les bordures d'un capot coopérant avec un support conformé de façon correspondante, mais est assurée par les panneaux plans eux-mêmes qui sont destinés à constituer la façade et les parois latérales de l'appareil.The invention proposes a solution which avoids these drawbacks in that the sealing is not ensured by the edges of a cover cooperating with a correspondingly shaped support, but is ensured by the flat panels themselves which are intended to constitute the front and side walls of the device.

Selon l'invention, la carcasse supérieure destinée à renfermer le brûleur et la chambre de combustion est essentiellement formée d'une même tôle pliée qui constitue la paroi arrière verticale, le couvercle supérieur horizontal et le fond inférieur horizontal ; entre les angles du couvercle et du fond sont fixées deux cornières en forme de V qui assurent la rigidité de la carcasse et délimitent avec elle les deux ouvertures latérales et l'ouverture frontale sur lesquelles sont appliqués les panneaux plats d'habillage qui assurent l'étanchéité par des joints portés par les panneaux eux-mêmes qui s'appliquent sur les bordures des ouvertures.According to the invention, the upper carcass intended to contain the burner and the combustion chamber is essentially formed from the same folded sheet which constitutes the vertical rear wall, the horizontal upper cover and the horizontal lower bottom; between the angles of the cover and the bottom are fixed two V-shaped angles which ensure the rigidity of the carcass and delimit with it the two lateral openings and the front opening on which the flat cladding panels which ensure the sealing by seals carried by the panels themselves which are applied to the edges of the openings.

D'autres caractéristiques particulières et avantages de l'invention apparaîtront à la lecture de la description qui va suivre d'un exemple de réalisation en référence au dessin annexé qui représente une vue en perspective partiellement éclatée de l'armature de l'appareil. La partie supérieure de l'appareil montre une même tôle pliée 1 qui constitue la paroi arrière verticale et qui se prolonge en haut pour former le couvercle supérieur horizontal 1a, et en bas pour former le fond inférieur horizontal 1b. Deux cornières verticales 2 en forme de V sont fixées aux deux angles du couvercle et du fond, dans deux échancrures correspondantes qui s'y trouvent prévues. La tôle 1 et les cornières 2 servant à rigidifier l'ensemble constituent la carcasse supérieure étanche de l'appareil qui délimite une chambre à l'intérieur de laquelle sont disposés le brûleur et la chambre de combustion non représentés, ainsi que la hotte 3 d'évacuation des gaz brûlés qui se raccorde par un orifice 4 prévu dans le couvercle 1a, à une tubulure non représentée. Un boîtier répartiteur d'air 5 est rapporté sur le couvercle et admet l'air frais dans la chambre par un orifice concentrique à l'orifice 4. Cette carcasse supérieure est fixée sur un socle que constitue la carcasse inférieure non étanche 6 à l'intérieur de laquelle se logent les mécanismes dont les tuyauteries traversent le fond 1 de façon étanche.Other particular characteristics and advantages of the invention will appear on reading the following description of an exemplary embodiment with reference to the appended drawing which represents a partially exploded perspective view of the frame of the apparatus. The upper part of the device shows the same folded sheet 1 which constitutes the vertical rear wall and which extends at the top to form the horizontal upper cover 1a, and at the bottom to form the horizontal lower bottom 1b. Two vertical angles 2 in the form of a V are fixed to the two corners of the cover and of the bottom, in two corresponding notches which are provided therein. The sheet 1 and the angles 2 serving to stiffen the assembly constitute the sealed upper carcass of the apparatus which delimits a chamber inside which the burner and the combustion chamber are not shown, as well as the hood 3 d 'evacuation of burnt gas which is connected by an orifice 4 provided in the cover 1a, to a pipe not shown. An air distributor box 5 is attached to the cover and admits fresh air into the chamber through an orifice concentric with the orifice 4. This upper carcass is fixed on a base which constitutes the non-tight lower carcass 6 to the inside of which are housed the mechanisms whose pipes cross the bottom 1 in a sealed manner.

Les bordures de la tôle pliée 1 et des cornières verticales 2 délimitant deux ouvertures rectangulaires latérales et une ouverture rectangulaire frontale. Les bordures de chacune de ces ouvertures se trouvent dans un même plan ce qui permet d'appliquer directement contre elles les panneaux d'habillage de l'appareil. L'étanchéité est assurée par des joints 9 collés sur les faces internes desdits panneaux au droit des bordures des ouvertures correspondantes contre lesquelles ils doivent s'appliquer. Les panneaux sont munis d'échancrures 10 destinées à les accrocher à des pattes d'accrochage non représentées prévues sur la carcasse supérieure des panneaux latéraux. Ils se prolongent avantageusement jusqu'au bas de la carcasse inférieure 6 à laquelle ils sont fixés également par un système non représenté. Les panneaux d'habillage (7, 8) assurent donc eux-mêmes l'étanchéité entre la chambre de combustion et l'extérieur. Leur démontage est extrêmement simple et permet un accès facile à l'intérieur de la chambre étanche.The edges of the folded sheet 1 and vertical angles 2 delimiting two lateral rectangular openings and a rectangular front opening. The edges of each of these openings are in the same plane which allows the covering panels of the device to be applied directly against them. Sealing is ensured by seals 9 bonded to the internal faces of said panels in line with the edges of the corresponding openings against which they must be applied. The panels are provided with notches 10 intended to hang them on hooks, not shown, provided on the upper carcass of the side panels. They advantageously extend to the bottom of the lower carcass 6 to which they are also fixed by a system not shown. The covering panels (7, 8) therefore themselves seal between the combustion chamber and the outside. Their disassembly is extremely simple and allows easy access to the interior of the sealed chamber.
