description An oven, is provided that includes multiple heat transfer means, including convection and microwave heat transfer means. The oven includes a cooking chamber, a blower and at least a shelf disposed within the cooking chamber. The shelf is designed to act as a food support as well as a conduit through which heated air passes into the cooking chamber. The microwave heating means comprises a microwave source and wave guide through which microwaves travel. The wave guide includes a plurality of openings through which microwaves can pass into said cooking chamber. In the preferred embodiment, the openings in the wave guide are positioned to correspond with the predetermined minima or maxima for the microwave wavelength propagating within the wave guide. An electric heating element may also be disposed within the cooking chamber to provide an alternative heating source. L'invention concerne un four comprenant de multiples dispositifs de transfert de chaleur, dont des dispositifs de transfert de chaleur par convection et par micro-ondes. Le four comporte une chambre de cuisson, un souffleur et au moins un plateau placé dans la chambre de cuisson. Le plateau sert de support d'aliments et de conduit par lequel l'air chauffé pénètre dans la chambre de cuisson. Le dispositif chauffant à micro-ondes comprend une source de micro-ondes et un guide d'ondes à travers lequel se déplacent les micro-ondes. Le guide d'ondes comprend plusieurs orifices par lesquels les micro-ondes peuvent pénétrer dans la chambre de cuisson. Dans le mode de réalisation préféré, les orifices du guide d'ondes sont placés de façon à correspondre aux minima et aux maxima de la longueur d'ondes des micro-ondes se déplaçant dans le guide d'ondes. Un élément chauffant électrique peut également être installé dans la chambre de cuisson afin de fournir une autre source de chaleur.
