Abstract
An electronic induction heat cooking apparatus includes a rectifier for rectifying an input voltage and outputting a direct current (DC) voltage, a plurality of switching elements for switching the DC voltage output through the rectifier, a plurality of heating coils for heating a cooking utensil by controlling the plurality of switching elements, a controller for controlling the plurality of switching elements, and a support member including grooves, into which the heating coils are inserted. A width of a cross section of each of the grooves decreases toward an entrance of each of the grooves.
