Abstract
An arrangement for feeding microwave energy from a microwave source (14) to the oven cavity (10) of a microwave oven comprises an elongated groove-shaped recess (16) in one of the conductive cavity walls (17), into which recess (16) microwave energy is fed at a centrally located feeding point (15). At its open side the recess (16) is covered by a rotatable conductive plate (22) arranged very close to the cavity wall (17) so that the recess (16) together with the plate (22) will form a waveguide-like structure. The plate (22) is shaped so that during its rotation time-varying feeding passages between the recess (16) and the oven cavity (10) are formed at both opposite ends of the recess, the passages allowing the transfer of microwave energy from the recess (16) to the cavity (10). These measures result in a very simple and space-saving arrangement of the 'dual feed' type.
