Induction heating cooker
An induction heating cooker includes a top plate on which an object to be heated is placed, a plurality of heating coils disposed adjacent to one another below the top plate to generate inductive magnetic fields to heat the object to be heated, a plurality of temperature detectors operable to detect a temperature of the object to be heated; and a controller operable to control operating states of the heating coils based on detection results of the temperature detector, wherein the plurality of temperature detectors are disposed widely below the top plate, and the number of the temperature detectors is less than the number of the heating coils.
1. An induction heating cooker comprising:
a top plate supporting an object;
a plurality of heating coils adjacent to one another below the top plate and configured to generate inductive magnetic fields to heat the object;
a plurality of temperature detectors operable to detect a temperature of the object,
wherein the plurality of heating coils are arrayed in a plurality of directions crossing each other and the temperature detectors are mounted to alternate heating coils in one of the plurality of directions; and
a controller configured to control operating states of the heating coils based on detection results of the temperature detectors,
wherein the plurality of temperature detectors are disposed widely below the top plate such that:
at least one of the temperature detectors resides below the object when the object resides above two adjacent heating coils, wherein the temperature detectors are each mounted to a central portion of one of the heating coils, and at least one of the two adjacent heating coils has no temperature detector; and
the number of the temperature detectors is less than the number of the heating coils.
2. The induction heating cooker according to claim 1 , wherein each of the heating coils has a circumferential length within a range of a circumferential length of a circle having an external diameter that ranges from 35 mm to 67 mm.
