Claim of US Patent No. 10,462,852

1. A system for measuring the temperature of cookware to be induction-heated, comprising:an induction heater having a countertop for supporting the cookware;
an infrared temperature sensor at least partially covered with a metal tube to narrow the field of view of the sensor;
a controller, an electronic storage medium, and an induction heating coil in responsive communication with the controller;
the countertop comprising a first material and having a viewing window comprising a second material located between the infrared temperature sensor and the cookware, wherein the viewing window prevents fluids or other physical contaminants from contacting the induction heater while providing visibility to infrared waves;
wherein a temperature of the cookware is sensed using the infrared temperature sensor, and the controller applies an algorithm stored in the electronic storage medium and utilizing a measured temperature of the metal tube, to adjust the sensed temperature to account for the narrowed field of view of the infrared temperature sensor, thereby providing a more accurate temperature of a portion of the heated cookware within the narrowed field of view.
