Abstract
A microwave oven is combined with gas heating, particularly for cooking foods for groups. The oven includes a cooking chamber, one or more magnetrons for the generation of microwaves, and several hollow heating elements arranged internally or on the walls of this chamber. The oven may also be provided with a conduit for the introduction of steam from an external boiler, in which products of the combustion of inflammable gases pass through these heating elements (5), and their interiors are not in communication with the interior of the chamber. These heating elements consist of essentially vertical tubes that at least partially cross this cooking chamber. The upper ends (11) of the gas exhausts of these heating elements (5) are closed by a box element (12), which is hermetically sealed to microwaves against the upper surface of the top (9) and has at least one hole (14). A corresponding second tube (15) is attached to edges of the hole and defines a microwave trap.
