Abstract

Ce four comprend un radiateur 26 émettant des micro-ondes dans la cavité 12 du four et un brûleur à gaz 90 dont les produits de combustion circulent dans le four, l'entrée et la sortie des gaz de combustion se produisant à travers des parois perforées dont les trous sont de diamètre inférieur d'une demi-longueur d'onde des micro-ondes. Des ventilateurs 64 introduisent les produits de combustion du gaz dans le four et servent en même temps à provoquer la sortie de ces gaz. Des ventilateurs 70 induisent un courant d'évacuation des produits de combustion et refroidissent la région de sortie. Toutes les zones du brûleur sont entourées de zones d'entrée d'air secondaire.This oven comprises a radiator 26 emitting microwaves in the cavity 12 of the oven and a gas burner 90 whose combustion products circulate in the oven, the entry and exit of the combustion gases occurring through perforated walls. whose holes are less than half a microwave wavelength in diameter. Fans 64 introduce the combustion products of the gas into the furnace and at the same time serve to cause these gases to escape. Fans 70 induce an exhaust current of combustion products and cool the outlet region. All burner zones are surrounded by secondary air inlet zones.
