1. An induction heating cooker comprising:
- a cooking table on which an object to be heated is placed;
at least two working coils and at least one temperature sensor disposed below the cooking table; and
at least two heat transfer members to transfer heat from the at least two working coils to the at least one temperature sensor,wherein the at least one temperature sensor is disposed radially outside the at least two working coils, and connected to the at least two working coils by the at least two heat transfer members, andwherein first ends of the at least two heat transfer members are disposed on a heating region of the at least two working coils between the at least two working coils and the cooking table and spaced apart from the at least two working coils, and second ends of the at least two heat transfer members are connected to the at least one temperature sensor.

16. An induction heating cooker comprising:
-
a main body; a cooking table disposed at a top of the main body such that an object to be heated is placed on the cooking table; a plurality of working coils disposed below the cooking table to heat the object; an inverter unit to supply high-frequency current to the working coils; a drive unit to turn a switching element of the inverter unit on/off; a controller to control the drive unit; at least one temperature sensor disposed between the working coils to measure temperature of the object; and at least two heat transfer members disposed around the at least one temperature sensor radially to transfer heat generated from the object heated by the working coils to the at least one temperature sensor, wherein the at least one temperature sensor is disposed radially outside the plurality of working coils, and connected to the working coils by the at least two heat transfer members, and wherein first ends of the at least two heat transfer members are disposed on a heating region of the at least two working coils between the at least two working coils and the cooking table and spaced apart from the at least two working coils, and second ends of the at least two heat transfer members are connected to the at least one temperature sensor. - View Dependent Claims (17, 18)
