Abstract

A microwave oven includes an oven cavity, into which HF power is fed from a microwave source, e.g. a magnetron energized by a power supply device. The power supply device with its components and the microwave source are cooled with the aid of a fan. The power supply device, the microwave source (12) and the fan (11) are combined into a so-called power module, which includes a substantially closed envelope (10) having an air inlet (15) and an air outlet (16), an input for the AC supply voltage and an output for HF power (30). The microwave source is mounted as a projecting part of the envelope at the air inlet or the air outlet of the power module. This makes it possible to adapt the power module to a great number of microwave oven constructions. The power module may be mounted at the top or bottom of the oven cavity or at the side of same. Feeding microwave energy into the oven cavity is possible both at the top and bottom thereof.
