Abstract
Description
La présente invention est relative aux grilles qui se trouven à la sortie des gaines véhiculant l'air chaud en provenance des sources de chauffage et plus particulièrement dans les systèmes dits de " récupération de chaleur" qui sont installés dans de nombreuses cheminées , ces grilles devant laisser passer un maximum de calories quand le système est en marche et empêcher l'air de la pièce de s' échapper par la gaine quand le système est arrêté. The present invention relates to the grilles which are found at the outlet of the ducts conveying the hot air coming from the heating sources and more particularly in the so-called "heat recovery" systems which are installed in many chimneys, these grilles in front allow a maximum of calories to pass while the system is running and prevent room air from escaping through the duct when the system is stopped.
Dans les dispositifs connus de ce genre, le réglage se fait manuellement et si l'on oublie de faire cette manipulation à l'aUumas et à l'extinction du système dechauffage la déperdition de calories peut être importante et de toute façon préjudiciable
Le dispositif suivant l'invention permet d'éviter cet inconvénient. I1 y a en effet derrière une façade décorative , un système d'obHturation automatique mis en mouvement par l'élévation ou la baisse de température à l'intérieur de la gaine. L'obturation est obtenue par 2 clapets mis par 2 lames d e métal, appelées couramment "bilame thermostatique". Ces dernières constituées essentiellement de 2 faces de métal, se dilatant de façon différente ont la propriété de se déformer sous l'effet de la chaleur.In the known devices of this kind, the adjustment is done manually and if one forgets to do this manipulation with the aumas and with the extinction of the heating system the loss of calories can be important and in any case prejudicial
The device according to the invention avoids this drawback. There is indeed behind a decorative facade, an automatic shutter system set in motion by the rise or fall of temperature inside the sheath. The obturation is obtained by 2 valves put by 2 metal blades, commonly called "thermostatic bimetal". The latter essentially consist of 2 metal faces, expanding in different ways have the property of being deformed under the effect of heat.
Selon d'autres caractéristiques et avantages de l'invention la forme et la position des clapets et par conséquent leur déplacement dans la virole d'accés à la grille favorisent l'écoulement des différents courant d'air chaud et d'air froid soit que ce soit l'ouverture ou la fermeture des clapets qui soit désirable. According to other characteristics and advantages of the invention, the shape and the position of the valves and consequently their displacement in the access shell to the grid favor the flow of the various streams of hot air and cold air, either it is the opening or closing of the valves which is desirable.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre en regard des dessins annexés qui représentent schématiquement et à titre d'exemple un mode de réalisation
Sur ces dessins
La figure 1 est une vue en coupe de l'appareil. La figure 2 est une double vue schématique en coupe illustrant les 2 positions extrêmes du dispositifXla figure 3 etant une
Comme on peut le voir à la figure I l'ensemble est constitué d'une virole 1 sur laquelle est fixée une façade 2 décorative en bronze massif ou tout autre matière et suffisamment ajourée pour laisser passer l'air chaud émanant du système de chauffage ou de récupération. A l'autre bout de la virole 1 et solidaire de cette dernière on trouve une armature3qui reçoit bs éléments de mécanisme.Other characteristics and advantages of the invention will emerge from the description which follows, with reference to the appended drawings which show schematically and by way of example an embodiment.
On these drawings
Figure 1 is a sectional view of the apparatus. Figure 2 is a schematic double sectional view illustrating the 2 extreme positions of the device, Figure 3 being a
As can be seen in Figure I the assembly consists of a ferrule 1 on which is fixed a decorative facade 2 in solid bronze or any other material and sufficiently perforated to allow the hot air emanating from the heating system or recovery. At the other end of the shell 1 and integral with the latter there is an armature 3 which receives elements of the mechanism.
Les clapets 4 sont reliés à l'armature par l'intermédiaire de charnières 5 , ces dernières permettant le débattement des dits clapets. The valves 4 are connected to the frame by means of hinges 5, the latter allowing the movement of said valves.
A la partie extrême de l'armature un axe 6 avec des entretoises 7 dont les dimensions correspondent à un écartement optimum reçoit les 2 bilames thermostatiques 8 . Quand ces dernières se déforment sous l"effet des variations de température, leurs extrémités qui coulissent dans les fentes 9 déplacent les clapets dans le sens désiré. La forme des clapets est parfaitement adaptée à la section de la gaine : clapet elleptique pour une gaine ronde, clapet rectangulaire pour une gaine carréeetc... le but recherché étant d'assurer une parfaite étanchéité. At the extreme part of the armature an axis 6 with spacers 7 whose dimensions correspond to an optimum spacing receives the 2 thermostatic bimetallic strips 8. When the latter are deformed under the effect of temperature variations, their ends which slide in the slots 9 move the valves in the desired direction. The shape of the valves is perfectly adapted to the section of the sheath: ellptic valve for a round sheath , rectangular valve for a square duct etc ... the aim is to ensure a perfect seal.
Comme on peut le voir sur la figure 2 les clapets passent de la position fermée à la position ouverte avec dans chaque position le sens des fluides qui contribuent au mouvement et renforcent l'étanchéité. As can be seen in Figure 2 the valves move from the closed position to the open position with in each position the direction of the fluids which contribute to the movement and reinforce the tightness.
I1 va de soi que le dispositif n'a été décrit et représenté qu'à titre purement explicatif, nullement limitatif et que diverses midifications pourraient être apportées à la forme de réalisation sans qu'on sorte pour autant du domaine de l'invention. C'est ainsi notamment que les bilames et les clapets pourraient avoir des formes différentes sans pour autant changer la finalité du système. It goes without saying that the device has only been described and shown for purely explanatory purposes, in no way limiting, and that various midifications could be made to the embodiment without departing from the scope of the invention. In particular, bimetallic strips and valves could have different shapes without changing the purpose of the system.
