Microwave oven
First Claim
1. A control unit for a microwave heating device, comprising:
- one or more radiation detectors for sensing a level of microwave power in a microwave chamber;
a modeling engine for tracking a relationship between the sensed level of the microwave power and a heatability property of an item in the microwave chamber; and
a controller for dynamically managing the microwave power emitted by a microwave source to the microwave chamber based on a signal from the modeling engine.

Abstract
Generally and not exclusively, a microwave cooking oven to cook food in a microwave chamber (e.g., a cooking chamber) includes a microwave power source, and a microwave control unit. In one implementation, the control unit includes an array of radiation detectors to detect the microwave power of multiple microwave beams in the cooking chamber, a modeler to map the temperature in different regions of an item in the microwave chamber, and a controller to adjust microwave power being delivered to each region of the item. In one implementation, the control unit can detect the presence and food type of an item in the microwave chamber. The control unit can provide a real time heating and cooking status of each region of an item being heated in the microwave chamber.
