Abstract
Description
La présente invention est relative à des perfectionnements aux récupérateurs de chaleur pour cheminées. The present invention relates to improvements to heat recuperators for fireplaces.
En ltétat actuel de la technique, il est connu de disposer le long de ltâtre et du contrecoeur d'une cheminée des conduits ouv-erts à leurs extrémités dont l'une débouche hors de la hotte. In the current state of the art, it is known to have along the hearth and reluctantly a chimney open ducts at their ends, one of which opens out of the hood.
De cette façon, l'air qui emprunte ces conduits est chauffé soit par les braises soit par la flamme du foyer et une partie de 1 1énergie calorifique est ainsi récupérée. In this way, the air which borrows these conduits is heated either by the embers or by the flame of the hearth and part of 1 1 calorific energy is thus recovered.
Un tel récupérateur de chaleur est avantageux mais, cependant, son rendement laisse à désirer. Such a heat recovery unit is advantageous but, however, its performance leaves something to be desired.
De plus, l'installation de tels récupérateurs est difficile dans les cheminées préfabriquées qui sont munies d'un avaloir artificiel. In addition, the installation of such recuperators is difficult in prefabricated chimneys which are provided with an artificial drain.
La présente invention, qui remédie à ces inconvénients, est remarquable en ce que les conduits, s'étendant le long du contrecoeur, aboutissent dans deux caissons latéraux disposés en vis à vis et présentant chacun une face oblique constituant une partie de l'avaloir artificiel usuel, lesdits caissons débouchant,. par un conduit, hors de la hotte de la cheminée. The present invention, which overcomes these drawbacks, is remarkable in that the conduits, extending along the reluctantly, end up in two lateral boxes arranged opposite and each having an oblique face constituting a part of the artificial drain. usual, said open boxes. through a flue, out of the chimney hood.
De cette façon, on réalise un récupérateur dont la mise en place est très aisée puisqu'il comporte solidairement l'avaloir. In this way, a recuperator is produced, the installation of which is very easy since it integrally comprises the drain.
Il faut noter aussi que l'avaloir, outre sa fonction de diriger les fumées vers le conduit d'évacuation, constitue une surface d'échange permettant de récupérer les calories contenues dans lesdites fumées. It should also be noted that the gutter, in addition to its function of directing the fumes towards the exhaust duct, constitutes an exchange surface making it possible to recover the calories contained in said fumes.
L'échange est favorisé par des volets déflecteurs permettant de diriger les fumées vers les surfaces échangeuses des caissons, lesdits volets qui permettent aussi d'obturer le conduit d'évacuation, étant articulés à la partie inférieure de l'avaloir. The exchange is favored by deflector flaps making it possible to direct the fumes to the exchange surfaces of the boxes, said flaps which also make it possible to close the discharge duct, being articulated at the bottom of the outlet.
D'autres caractéristiques apparaîtront mieux par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels:
La figure 1 est une vue en élévation montrant une cheminée pourvue d'un récupérateur conforme à l'invention
La figure 2 est une vue en perspective montrant, à plus grande échelle, le récupérateur de l'invention;
La figure 3 est une vue de détail à plus grande échelle encore.Other characteristics will appear better from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is an elevational view showing a chimney provided with a recuperator according to the invention
Figure 2 is a perspective view showing, on a larger scale, the recuperator of the invention;
Figure 3 is a detail view on a still larger scale.
En se reportant aux dessins on voit que, de la façon connue, le récupérateur est constitué par une pièce 1 en forme d'équerre, affectant une section en U et formant,en combinaison avec l'âtre A et le contrecoeur C,un canal 2 ouvert à ses deux extrémités. Referring to the drawings, it can be seen that, in the known manner, the recuperator consists of a piece 1 in the form of a square, affecting a U-shaped section and forming, in combination with the hearth A and the reluctant C, a channel 2 open at both ends.
Selon l'invention, le canal 2 aboutit à deux caissons 3 latéraux pourvus chacun d'un embout tubulaire 4 débouchant par exemple sur le côté de la hotte H de la cheminée. According to the invention, the channel 2 leads to two lateral boxes 3 each provided with a tubular end piece 4 opening for example on the side of the hood H of the chimney.
Chaque caisson-3 présente une face 5 oblique formant, en coopération avec l'autre caisson, l'avaloir usuel. Each box-3 has an oblique face 5 forming, in cooperation with the other box, the usual dump.
L'air chauffé par conduction dans le canal 2 sous l'action des calories dégagées par les braises et les fumées pénètre par un orifice 6 ( figure 2) dans chacun des deux caissons 3 dont la face 5 constitue une surface échangeuse. The air heated by conduction in the channel 2 under the action of the calories released by the embers and the fumes enters through an orifice 6 (FIG. 2) in each of the two boxes 3, the face 5 of which constitutes an exchange surface.
Le rendement de l'échange calorifique entre l'air contenu dans les caissons et les fumées- est favorisé par la présence à l'intérieur desdits caissons d'ailettes 7. The efficiency of the heat exchange between the air contained in the boxes and the fumes is favored by the presence inside said boxes of fins 7.
Selon un mode de réalisation, les ailettes 7 sont réalisées en un matériau bon conducteur de la chaleur (du cuivre par exemple) et elles traversent les faces 5 pour s'étendre à l'extérieur des caissons le long desdites faces comme montré sur la figure 3. According to one embodiment, the fins 7 are made of a material which is a good conductor of heat (copper for example) and they pass through the faces 5 to extend outside the boxes along said faces as shown in the figure 3.
Selon une autre caractéristique de l'invention, l'ob- turateur usuel du conduit d'évacuation E est constitué par deux volets 8 articulés en 9 par un de leurs côtés à la base de l'avaloir formé par les faces 5 des caissons. According to another characteristic of the invention, the usual shutter of the evacuation duct E is constituted by two flaps 8 articulated at 9 by one of their sides at the base of the drain formed by the faces 5 of the boxes.
Selon l'invention, les volets 8 ont pour fonction de diriger les fumées vers les caissons 3 et d'augmenter ainsi le taux de récupération des calories contenues dans celles-ci. According to the invention, the flaps 8 have the function of directing the fumes towards the boxes 3 and thus increasing the rate of recovery of the calories contained in them.
Naturellement, divers moyens peuvent être utilisés pour maintenir les volets selon l'inclinaison requise,l'axe de rotation de ces derniers étant contenu dans un plan passant sensiblement par la base de l'avaloir. Naturally, various means can be used to maintain the flaps at the required inclination, the axis of rotation of the latter being contained in a plane passing substantially through the base of the hood.
