METHOD AND DEVICE FOR ELECTROMAGNETIC COOKING USING ASYNCHRONOUS SENSING STRATEGY FOR RESONANT MODES REAL-TIME TRACKING

摘要

An electromagnetic cooking device (10) includes an enclosed cavity (20) configured to receive a food load, a plurality of high power amplifiers (18A-18D) and RF feeds (26A-26D) for introducing electromagnetic radiation into the cavity (20), and a controller (14) for controlling the frequency, phase and amplitude of the electromagnetic radiation fed into the cavity (20) by the RF feeds (26A-26D). The controller (14) is configured to identify resonant modes, develop and implement a heating strategy based on the resonant modes, utilize an asynchronous manager to automatically detect when a variable has changed to a degree that requires an updated identification of resonant modes and an updated heating strategy, and if the asynchronous manager determines that updates are needed, repeat the steps above to determine a new heating strategy, otherwise continue with the current heating strategy.
