Title
(EN) ATMOSPHERIC GAS BURNER FOR COOKING APPLIANCES
(FR) BRÛLEUR À GAZ ATMOSPHÉRIQUE POUR APPAREILS DE CUISSON
Abstract
(EN) Atmospheric gas burner (10; 110) of the partially-aerated type for a cooking appliance, comprising a lower cup (1; 101) and means for constraining it to a top (4; 104) of the cooking appliance, an intermediate body (2; 102) which is constrained to and overlaps said lower cup and which has a central deliver chamber (9b; 109b) for delivering the fuel mixture, that is provided with its own central flame spreader, and at least one perimeter delivery chamber (9a; 9c; 109a; 109c) for delivering the fuel mixture, that surrounds at least partially said central chamber and that is provided with two perimeter flame spreaders, and means (3a; 3b; 103) for the upper covering of said central chamber and of said two perimeter chambers, wherein said central chamber and said two perimeter chamber are fluidically separated from each other, and wherein each of said delivery chambers comprises at least one own mixer (8a; 8b; 8c; 108a; 108b; 108c) with radial Venturi effect supplied by a respective injector (6a; 6b; 6c; 106a; 106b; 106c) housed in said lower cup. Advantageously, said lower cup comprises a respective housing (5a; 5b; 5c; 105a; 105b; 105c) for each of said injectors, each of said housings for said injectors being fluidically separated from each of the other housings, at least when said intermediate body of the burner is constrained to said lower cup.
(FR) L'invention concerne un brûleur à gaz atmosphérique (10 ; 110) du type partiellement aéré pour un appareil de cuisson, comprenant une coupelle inférieure (1 ; 101) et des moyens pour la limiter à une partie supérieure (4 ; 104) de l'appareil de cuisson, un corps intermédiaire (2 ; 102) qui est limité à ladite coupelle inférieure et qui la chevauche et qui présente une chambre de distribution centrale (9b ; 109b) pour distribuer le mélange combustible, qui est pourvu de son propre diffuseur de flamme central et d'au moins une chambre de distribution périphérique (9a ; 9c ; 109a ; 109c) pour distribuer le mélange combustible, qui entoure au moins partiellement ladite chambre centrale et qui est pourvu de deux diffuseurs de flamme périphériques et des moyens (3a ; 3b ; 103) pour le recouvrement supérieur de ladite chambre centrale et desdites deux chambres périphériques, ladite chambre centrale et lesdites deux chambres périphériques étant fluidiquement séparées les unes des autres et chacune desdites chambres de distribution comprenant au moins un mélangeur propre (8a ; 8b ; 8c ; 108a ; 108b ; 108c) avec un effet Venturi radial fourni par un injecteur respectif (6a ; 6b ; 6c ; 106a ; 106b ; 106c) logé dans ladite coupelle inférieure. Avantageusement, ladite coupelle inférieure comprend un logement respectif (5a ; 5b ; 5c ; 105a ; 105b ; 105c) pour chacun desdits injecteurs, chacun desdits logements pour lesdits injecteurs étant fluidiquement séparé de chacun des autres logements, au moins lorsque ledit corps intermédiaire du brûleur est limité à ladite coupelle inférieure.
