CLOSED-LOOP MICROWAVE POPCORN CONTROL |
摘要 |
A closed-loop control for sensing the completion of popcorn popping in a microwave oven and automatically shutting down the oven. A sensor is acoustically coupled to the microwave oven cavity and provides an electrical signal to an amplifier and filter. The amplified and filtered signal is processed by a pop detector which includes an integrator and shut-down command generator responsive to a decreasing rate of popping to shut the oven off. The integrator provides a pre-pop timer function to maintain the oven on until popping commences.
