Abstract
A self-cleaning microwave oven is characterised in that, in use, microwave energy is injected into the oven by a rotating radiator 30, Fig. 5, protected from spillage by a radiation-transparent cover 34. As described, energy from a magnetron passes along a wave guide 18 and is coupled 40 to a coaxial line, comprising a fixed outer 26 and a in motor-driven inner 22, connected to the radiator 30 by an impedance matching cone 52, which allows the energy to pass into a plenum 28 from where it radiates, via slots 32, Fig. 4, into the oven. In order that the energy shall be radiated in various phases and in various polarisation modes (thereby to achieve more uniform cooking), the plenum 28 is irregular, as shown dotted in Fig. 4, and the slots 32 are unequal and irregularly positioned, one slot also being covered by a lip 56, Fig. 5. During cooking air is blown into the waveguide 18 and hence into the oven, and during self-cleaning, when the oven is heated conventionally by resistance heaters, air is drawn into the oven through the waveguide 18 by convection. <IMAGE>
