ABSTRACT:
A self-contained microwave radiation detector is adapted for use in a microwave oven. The detector includes a non-metallic electrodeless sealed chamber in which a microwave-responsive gas mixture, such as a mixture of neon and argon, is located. In response to excitation by the microwaves radiation in the microwave oven, the gas mixture sustains a white glow which provides a positive indication that the microwave oven is in operation irrespective of the operation of other indicators. The non-metallic and electrodeless construction of the detector allows it to remain within the oven during extended periods of operation without damage to the oven or the detector. Also described is an improved microwave oven cooking utensil into which the detector has been integrated. The improved utensil includes a platform for receiving the food to be cooked, a base for supporting the platform in the oven and a microwave heater adjacent the platform, the heater being formed by a sealed chamber containing a microwave-responsive gas or gas mixture. In the presence of microwave energy in the oven, the gas or gas mixture sustains a glow which heats the platform and food thereon as well as provides a visual indication, associated with the utensil, of the presence of microwave energy.
