ABSTRACT:
A microwave oven has an oven-defining housing structure having an electric lamp used to illuminate the interior of the oven-defining housing structure, that is, a heating chamber. The oven-defining housing structure has a control panel at the front thereof, which control panel includes one or more signaling windows or indicators to be illuminated, for example, one signaling window representing, when illuminated, that the high frequency wave generator is in position to generate a low radiating energy into the heating chamber and the other signaling window representing, when illuminated, that the high frequency wave generator is being operated. These signaling windows are respectively illuminated by portions of rays of light emitted by the oven lamp by means of light transmitters. Respective shutter mechanisms are provided for controlling passage of the light rays from the oven lamp towards the signaling windows so that the latter can be illuminated at required times.
