Induction heating device and method for sensing a cooking vessel on an induction heating device

An induction heating device including:

• a plate configured to receive a cooking vessel thereon;
• a working coil provided below the plate that heats the cooking vessel using an inductive current;
• a cooking vessel sensor provided concentrically with the working coil such that the working coil surrounds the cooking vessel sensor;
• and
• a controller configured to apply a sensing current to the sensing coil to generate a resonant signal and determine whether the cooking vessel has an inductive heating property based on the generated resonant signal,
• wherein the cooking vessel sensor includes:
• a body having a first receiving space, a side wall, and a sensing coil wound by a predetermined number of winding counts on an outer face of the side wall of the body;
• a magnetic core received in the first receiving space, wherein the magnetic core has a hollow cylindrical shape and a second receiving space formed inside the magnetic core;
• and
• a temperature sensor received in the second receiving space.
