Title: ELECTROMAGNETIC COOKING DEVICE WITH AUTOMATIC MELT OPERATION AND METHOD OF CONTROLLING COOKING IN THE ELECTROMAGNETIC COOKING DEVICE
Abstract:
An electromagnetic cooking device and method of controlling the same is provided herein. The cooking device includes a cavity in which a food load is placed and a plurality of RF feeds configured to introduce electromagnetic radiation into the cavity for heating the food load. A controller is provided and is configured to: (a) measure resonances in the cavity; (b) generate a resonance map resulting from the measured resonances; (c) conditionally repeat steps (a) and (b); (d) detect a melting state of the food load based on variations between the resonance maps; and (e) adjust a power level of the electromagnetic radiation in response to detection of the melting state.
