Wireless kitchen appliance operated on induction heating cooker
First Claim
1. A kitchen appliance, for being wirelessly operated on an induction heating cooker with power transmitted by an induction coil of the induction heating cooker, the kitchen appliance comprising:
- a microcontroller;
one or more electronic circuits electrically coupled to the microcontroller;
power control circuitry that supplies the microcontroller and the one or more electronic circuits with low level DC voltage, the power control circuitry including a rectifier that is disposed in the power control circuitry and that converts AC voltage to the DC voltage and a buffer capacitor that filters the DC voltage at an outlet of the rectifier, the power control circuitry further including a peak voltage tracker that tracks peak values of the DC voltage at the outlet of the rectifier and provides feedback to the microcontroller, the peak voltage tracker coupled to and disposed between the rectifier and the buffer capacitor;
two or more receiver coils that partially collect the power generated by the induction coil and provide transfer of the collected power to the power control circuitry, the two or more receiver coils including a first receiver coil and a second receiver coil; and
a switch that activates the first receiver coil and the second receiver coil in a first switch-position and that deactivates the first receiver coil and activates the second receiver coil in a second switch-position, wherein the microcontroller controls the switch between the first switch-position and the second switch-position based on the feedback provided by the peak voltage tracker.
