(54) A GLASS-CERAMIC COOKING APPARATUS AND A METHOD RELATING TO TEMPERATURE LIMITING CONTROL FOR PREVENTING COOKING OIL IGNITION


(57) A glass-ceramic cooking apparatus and a method relating to temperature limiting control of the glass heating area for preventing cooking oil ignition is disclosed. The apparatus comprises at least one glass surface (201), at least one heat source (103) under the glass to create a heating area (202) on the glass, one temperature sensor (303) and one control unit (302) for each heat source (103), wherein the sensor (303) measures the temperature on the underside the glass heating area (202), and the control unit is electrically connected with the heat source (103), compares the measured glass temperature with predetermined upper and lower temperature limits that are based on a corresponding relationship between the heating area temperature and the cooking oil temperature within the cooking vessel, and then reduces or increases the output power of the heating source (103), so that the maximum temperature of the cooking oil in the cooking vessel can be limited in a range that is below the cooking oil ignition point while a minimum temperature can still be maintained for a desired cooking performance.
