Description

Economiseui# pour fourneaut ä gaz. Dans des fourneaux ä gaz connus, tels que des reelrauds, cuisinieres ete., Fustensile de cuisson se place directemerrt sur une grille, au-dessus du brüleur dopt les gaz chauds, tont en lechant 1'exterieur dune Partie des parois de I''usterisile, se repandent directernent Jans Fair libre auquel ils abandonnent une notable Partie de leur chaleur qm est ainsi pratiquement inutilisee. Saver # for gas stove. In known gas stoves, such as stoves, stoves, etc., the cooking utensil is placed directly on a grate, above the burner taking up the hot gases, while touching the outside of part of the walls of the oven. useless, spread directly from the free Jans Fair to which they give up a considerable part of their heat which is thus practically unused.

La presente invention concerne un econo- miseur pour fourneaux ä. gaz dort 1e but est d'utiliser une Partie de cette chaleur perdue et, par Suite, de realiser une economie de cornbustible. The present invention relates to an economizer for stoves. The goal is to utilize some of this waste heat and thereby save fuel.

Une forme d'execution de 1'economiseur monte Sur un fourneau est donnee, schemati- quement et ä titre d'exemple, au dessin an- nexA dass lequel: Fig. 1 en est une coupe verticale, et Fig. 2 une vue en plan. A form of execution of the economizer mounted on a stove is given, schematically and by way of example, in the appended drawing A in which: FIG. 1 is a vertical section, and Fig. 2 a plan view.

L'economiseur represente cornporte un re- cipient a dort la forme generale est Gelle dune couronne; sa paroi interieure 1, ondulee, est legerement conique en s'evasant vors 1e haut, sa paroi exterieure k presente egalement quelques ondulations, son fond est en forme The economizer represented comprises a sleeping receptacle the general shape is like a crown; its inner wall 1, corrugated, is slightly conical while widening towards the top, its outer wall k also has some undulations, its bottom is shaped

de degre in n, et sa paroi superieure o est pereee d''une ouverture e pouvant etre ferrnee par un couvercle f. of degree in n, and its upper wall o is pierced with an opening e which can be closed by a cover f.

Cet economiseur est place sur un rechaud ä gaz c dont an a prealablement enleve la grille dort sont generalement pourvus Ges appareils; Feconomiseur repose alors sur 1e rechaud par la Partie superieure in de son fond, sa Partie inferieure ia entorrrant 1e brrü leur d qui se trouve ainsi engage dans la Partie centrale libre b de la couronne. L'us tensile de crrisson, la casserole h, est intro duit dass cette meme Partie centrale libre, par 1e haut de celle-ci, et y est maintenue par 1e cer-cle g reposant Sur 1e recipient a. This economizer is placed on a gas stove, the grid of which has been removed beforehand, the appliances are generally provided with; The economiser then rests on the stove by the upper part in of its bottom, its lower part ia entorrrant 1e burner d which is thus engaged in the free central part b of the crown. The tensile utensil of crrisson, the pan h, is introduced dass this same free central part, by the 1st top thereof, and is maintained there by the 1st cer-key g resting on the 1st container a.

La conicite du cone forme par la paroi l correspond approximativement ä Gelle des cas seroles et autres rrstensiles de ce genre, mais la paroi interieure du recipient pourrait aussi etre cylindr-iclue ou meme conique dann 1'au tre sens. The conicity of the cone formed by wall 1 corresponds approximately to that of serole cases and other such devices, but the interior wall of the container could also be cylindrical or even conical in the other direction.

Le cercle g, muntre en traits rnixtes en fig. 2, presente une encoche p dans laquelle est engage 1e rebord de 1'or.werture e. The circle g, shown in mixed lines in fig. 2, has a notch p in which is engaged the first edge of 1'or.werture e.

Cet economiseur est specialement destine ä contenir un liquide, de 1'eau par exemple, qui est introduite par 1'ouverture e et peut en etre retiree par 1e robinet d'ecoulemerit i. This economizer is specially intended to contain a liquid, water for example, which is introduced through the opening e and can be withdrawn therefrom through the drain valve i.

0n comprend aisement que, par 1'emploi de 1'economiseur a Sur 1e rechaud c comme 1e montre 1e dessin, les gaz chauds, au Heu de se repandre directement ä fair libre, sollt contraints de s'elever (ans 1'espace compris entre Ja casserole h et Ja paroi d pour com- muniquer la plus Brande Partie de leur oha- leur aux contenus de la casserole et de 1'econo- miseur; Ges gaz peuvent alors s'ecliapper par les interstices qui existent inevitablenient entre 1e cercle g et la paroi o de 1'economiseur. L'eau contenue dass ce dernier absorbe ainsi une Brande quantite de la chaleur qui sei-alt sann cela perdu, et cet economiseur permet de realiser de la sorte une economie de com- bustible. It is easy to understand that, by the use of the economizer a On the stove c as shown in the drawing, the hot gases, instead of spreading directly to free air, are forced to rise (in the space included between pan h and wall d to communicate most of their heat to the contents of the pan and the economizer; the gases can then escape through the interstices which inevitably exist between the circle g and the wall o of the economizer.The water contained in the latter thus absorbs a Brande quantity of the heat which should not be lost, and this economizer makes it possible to achieve a saving of fuel in this way.

La paroi interieure du recipient pourrait ne. pas presenter d'ondulations, mais celles-ei augmentent la surface de chauffe et par Suite 1e rendement de 1'economiseur. Quant aux ondulations de la paroi exterieure, qui pour- raient aussi ne pas exister, olle servent ä, donner un aspect agreable ä 1'economiseur. The inner wall of the container could not. not present undulations, but these ei increase the heating surface and consequently the 1st efficiency of the economizer. As for the undulations of the external wall, which could also not exist, they serve to give a pleasant appearance to the economizer.

Pour 1'echappement des gaz chauds, 1'eco- nomiseur pourrait aussi etre muni dune che- min6e, ou de petits chenaux radiaux formes (ans sa paroi sup6rieure par des ondulations en creux de celle-ci, dont un, r, est montre en traits mixten en fig. 1. For the escape of the hot gases, the economizer could also be provided with a chimney, or small radial channels formed (in its upper wall by hollow undulations of the latter, one of which, r, is shown in mixed lines in Fig. 1.

L'ouverture (ans la paroi superieure de 1'economiseur, et par Suite 1'encoche du cercle, pourraient presenter d'autres formen que Gelles decrites. L'ouverture centrale eireulaire du cercle g doit etre dimensionn@e suivarit la grandeur des ustensiles de cuisson, et il est avantageux de prevoir plusieurs cercles ä o(i- verturea centrales differentes. L'economiseur selon 1'invention peut etre utilisee comme bouilloire, et, suivant 1e type du fourneau et du brüleur, il peut presenter des formen altre que Gelles montrees au dessin. The opening (in the upper wall of the economiser, and subsequently the notch of the circle, could have other shapes than those described. The circular central opening of the circle g must be sized according to the size of the utensils of cooking, and it is advantageous to provide several circles with different central o (i- virtuereas. that Gelles shows in the drawing.
