Induction Heating Loaded-Object Sensor

The patent divides the pot compatibility determination process into two distinct stages: a preliminary detection stage using low power levels to screen potential candidates, and a verification stage using higher power levels only on promising candidates. This segmentation allows the system to maintain measurement accuracy while dramatically reducing overall power consumption compared to using high power levels throughout the entire determination process.

The patent applies partial action by using minimal power levels (less than 1W) for the initial detection phase, which is sufficient to identify pots with ferromagnetic properties. Only after this preliminary screening confirms compatibility does the system escalate to higher power levels for verification, thereby avoiding unnecessary high power consumption while maintaining determination accuracy.

The patent implements feedback mechanisms through sensors that detect the magnetic properties of the pot material in real-time. This feedback allows the control system to identify whether the pot is suitable for induction heating and provide appropriate user guidance, thereby maintaining reliable operation with compatible pots while expanding adaptability by clearly communicating compatibility status for various pot materials.

The patent introduces an intermediary detection system that acts as a mediator between the induction heating device and various pot materials. This intermediary sensor system detects magnetic properties and translates them into compatibility information, allowing the device to effectively work with suitable materials while providing clear feedback about incompatible materials, thus expanding overall adaptability without compromising reliability.
