Abstract (en)

[origin: EP0284958A1] In order to achieve better decoupling between the microwave transmitter (1) and the cooking chamber (3) in a microwave oven, the microwave field is guided by a waveguide (2) into a resonator cavity (5), which is connected to the cooking chamber (3) via injection openings (6). The resonator cavity (5) forms a metallically sealed box. As a result of the design of the injection openings (6) and the arrangement of coupling pins (9) in the resonator cavity, it is possible to direct the microwave field in all dimensions, before and during injection into the cooking chamber. In addition, a field distributor can move the microwave field in all three dimensions. An optimum heat distribution in the cooking chamber can be achieved overall. <IMAGE>
