SETT OCH ANORDNING FOR REGLERING AV TEMPERATUROKNING FOR FOREMAL, SOM UPPVERMES I EN MIKROVAGSUGN

摘要

A method and apparatus is disclosed for controlling the temperature rise of a material placed in a microwave oven in which use is made of a correlation between the power delivered to the load and the residual field within the oven at a position spaced away from the load. By sensing the strength of the electromagnetic field, electronic circuitry is provided for evaluating the time required to achieve a given temperature rise of the material being heated.
