Cooking vessel sensor and induction heating device including a cooking vessel sensor

An induction heating device including:

• a plate configured to receive a cooking vessel therein;
• at least one working coil provided below the plate that heats the cooking vessel using an inductive current;
• a coil base that fixes the working coil to the induction heating device;
• a cooking vessel sensor provided concentrically with the working coil, wherein the cooking vessel sensor includes a sensing coil and wherein the working coil surrounds the cooking vessel sensor;
• and
• a controller that applies a sensing current to the sensing coil and determines, based on a sensing result of the cooking vessel sensor, whether the cooking vessel has an inductive heating property, wherein the cooking vessel sensor includes:
• a body having a side wall and a first receiving space, wherein the side wall has a coil outlet;
• a magnetic core received in the first receiving space, wherein the magnetic core has a hollow cylindrical shape, and a second receiving space is formed inside the magnetic core;
• a temperature sensor received in the second receiving space;
• and
• a first outer face of the side wall on which the sensing coil is wound by a predetermined number of winding counts, wherein the sensing coil passes through the coil outlet out of the body.
