Abstract

Hot air exhaust port with automatic opening and closure for heat recuperators of open furnaces. The air port 2 comprises a fixed casing 1 into which is fitted and to which is fastened the port 2, comprising openings 3 and a movable shutter 5, on which a dilatation element 8 with a thruster 7 is fastened, and a spring 12 making it possible for the movable shutter to open or close the port according to the temperature level of the air which reaches it. Application to heat recuperaters of open furnaces.

Description

La presente invention concerne un dispositif permettant d'ouvrir et de fermer automatiquement les bouches de sortie d'air chaud des récupérateurs de chaleur des foyers ouverts. The present invention relates to a device for automatically opening and closing the hot air outlet vents of heat recuperators of open fireplaces.

Les bouches existantes connues doivent être ouvertes manuellement au début de la combustion dans le foyer et fermees egalement manuel le ment à la fin de la combustion. Known existing mouths must be opened manually at the start of combustion in the hearth and also closed manually at the end of combustion.

Ces bouches présentent d'importants inconvénients car si l'on oublie de les ouvrir, pendant toute la durée de la combustion, les calories normalement produites par le récupérateur ne seront pas diffusées dans la pièce ou les pièces. These vents have significant drawbacks because if we forget to open them, during the entire duration of combustion, the calories normally produced by the recuperator will not be diffused into the room or rooms.

D'autre part, les récupérateurs de chaleur des foyers ouverts ayant une prise d'air frais ou même froid, soit en sous-sol, soit à l'extérieur, si l'on oublie de fermer les bouches, à la fin de la combustion, de l'air froid envahit la pièce, ou les pièces chauffees par le recuperateur de chaleur provoquant en une nuit par exemple, une baisse très sensible de la température à l'intérieur de la pièce ou des pieces. On the other hand, the heat recuperators of open hearths having a fresh or even cold air intake, either in the basement or outside, if we forget to close the vents, at the end of the combustion, cold air invades the room, or rooms heated by the heat recovery causing overnight, for example, a very significant drop in temperature inside the room or rooms.

Le-dispositif suivant l'invention, permet d'éviter ces importants inconvénients. Avec celui-ci, les bouches de sortie d'air s'ouvriront automatiquement lorsque l'air chaud y parviendra et se refermeront automatiquement lorsque le foyer sera eteint et que de l'air froid y parviendra. The device according to the invention makes it possible to avoid these significant drawbacks. With this, the air outlet vents will open automatically when the hot air reaches it and will close automatically when the fireplace is turned off and cold air reaches it.

Le dispositif objet de l'invention est composé d'un élément à dilatation dont les caractéristiques sont particulierement adaptées, comportant un poussoir s'allongeant ou se rétractant suivant le niveau de température de l'air dans lequel il est soumis. The device which is the subject of the invention is composed of an expansion element, the characteristics of which are particularly suitable, comprising a pusher extending or retracting depending on the temperature level of the air in which it is subjected.

Cet élément à dilatation associé à un volet mobile et un ou plusieurs ressorts permet l'ouverture et la fermeture automatique de la bouche. This expansion element associated with a movable flap and one or more springs allows the mouth to be opened and closed automatically.

Les dessins annexés illustrent à titre d'exemple, un des modes de réalisation conforme à l'invention. The accompanying drawings illustrate by way of example, one of the embodiments according to the invention.

La figure 1 représente la bouche en position ouverte, vue suivant F de la figure 2. FIG. 1 represents the mouth in the open position, seen along F of FIG. 2.

La figure 2 est une coupe selon AA de la figure 1 et représente également la bouche en position ouverte. Figure 2 is a section along AA of Figure 1 and also shows the mouth in the open position.

La bouche d'air montrée aux figures 1 et 2 est entièrement métallique et comprend un boitier (1) encastre dans la hotte de la cheminée ou dans une cloison et sur lequel sera raccordée la gaine venant du récupérateur de chaleur.  The air outlet shown in Figures 1 and 2 is entirely metallic and includes a box (1) built into the hood of the chimney or in a partition and to which will be connected the sheath coming from the heat recovery unit.

Dans ce boitier, viendra s'emboiter le dispositif à ouverture et fermeture automatique dont la partie fixe (2) pourra y être fixée par des vis. In this case, the automatic opening and closing device will fit together, the fixed part (2) of which can be fixed to it by screws.

Cette partie fixe comporte des ouvertures rectangulaires (3) par lesquelles sortira l'air chaud, des patins (4) assurant le guidage et le maintien du volet mobile (5) et un dispositif (6) de butée comprenant au moins un ressort de forte résistance destiné à absorber la sortie résiduelle du poussoir (7) de l'élément à dilatation (8). This fixed part has rectangular openings (3) through which the hot air will emerge, pads (4) guiding and maintaining the movable flap (5) and a stop device (6) comprising at least one strong spring. resistance intended to absorb the residual output of the pusher (7) from the expansion element (8).

Sur le volet mobile qui comporte également des ouvertures rectangulaires (9) est fixé un support (10) comportant un trou taraudé dans lequel sera vissé l'élément à dilatation (8) qui y sera immobilisé par un ecrou de blocage (11). On the movable flap which also has rectangular openings (9) is fixed a support (10) comprising a threaded hole in which will be screwed the expansion element (8) which will be immobilized there by a locking nut (11).

Un ressort de compression (12) dont la force est prévue à cet effet, est intercalé entre la collerette de l'élément à dilatation (8) et la paroi de la partie fixe (2) de la bouche. A compression spring (12), the force of which is provided for this purpose, is interposed between the collar of the expansion element (8) and the wall of the fixed part (2) of the mouth.

Après allumage du feu dans le foyer, l'air chaud dégage par le récupérateur arrivant à la bouche fermée, le poussoir (7) de l'élément à dilatation (8) sortira progressivement de son -fourreau et, étant en appui sur la butee (6), repoussera le volet mobile (5) mettant en vis -vis les ouvertures (3) de la partie fixe (2) et les ouvertures (9) du volet mobile (5) permettant ainsi à l'air chaud de s'échapper. After lighting the fire in the hearth, the hot air released by the recuperator arriving with the mouth closed, the pusher (7) of the expansion element (8) will gradually come out of its sleeve and, being supported on the stop (6), push back the movable flap (5) putting opposite the openings (3) of the fixed part (2) and the openings (9) of the movable flap (5) thus allowing the hot air to escape.

La bouche restera ouverte tant que de l'air chaud y parviendra. The mouth will remain open as long as hot air does.

Lorsque le feu sera éteint dans le foyer, que le récupérateur se refroidira progressivement, que de l'air de moins en moins chaud arrivera à la bouche, le poussoir (7) de l'élément à dilatation (8) se rétractera dans son fourreau, le ressort (12) repoussera l'ensemble volet mobile (5). When the fire is extinguished in the hearth, that the recuperator cools gradually, that less and less hot air arrives at the mouth, the pusher (7) of the expansion element (8) will retract in its sheath , the spring (12) will push the movable flap assembly (5).

Les parties pleines du volet mobile (5) venant obturer les ouvertures (3) de la partie fixe (2) la bouche sera alors fermée interdisant le passage de l'air froid. The solid parts of the movable flap (5) closing the openings (3) of the fixed part (2) the mouth will then be closed preventing the passage of cold air.

Bien entendu, la présente invention ne se limite pas à la forme d'exécution decrite ci-dessus. D'autres formes d'exécution peuvent être envisagées mettant en oeuvre des moyens équivalents pour cette application.  Of course, the present invention is not limited to the embodiment described above. Other embodiments can be envisaged using equivalent means for this application.
