Cook-by-weight microwave oven

摘要

A microprocessor controlled microwave oven having a scale for providing a signal corresponding to the weight of a food body in the cavity to the microprocessor. Through a control panel, the operator inputs a second signal corresponding to the initial temperature of the food body. From these signal inputs, the microprocessor calculates the microwave exposure time period to raise the temperature of the food body to a predetermined temperature or to cook the food body. In accordance with the time period, the microprocessor then controls the magnetron through one or more active cycles as selected.
