Abstract
A combined microwave and self-cleaning oven has a choke surrounding the oven liner with the opening of the choke cavity adjacent the lip of the liner. The choke cavity has a rib at each of several groundpoints to trap air within the cavity. This trapped air thermally insulates the oven liner lip region so that pyrolytic self-cleaning of the oven can be accomplished without the aid of a mullion heater. For best electrical effectiveness, the choke groundpoints are preferably spaced a distance of between one-half and one wavelength.
