Abstract: The present disclosure relates to a loaded-object sensor and an induction heating device including the loaded-object sensor. The loaded-object sensor has a cylindrical hollow body with a sensing coil wound on its outer surface. Further, a receiving space formed inside the body of the loaded-object sensor accommodates a temperature sensor. The loaded-object sensor is concentrically provided in a central region of the working coil. The sensor may measure the temperature of the loaded object while discriminating a type of the loaded object placed on a corresponding position to the working coil.

Abstract: The present disclosure relates to an induction heating device and a method for controlling the same. In accordance with the present disclosure, first, inductive sensing is periodically performed to detect a specific object with inductive heating property. Next, current sensing of the specific object having the inductive heating property is performed to again check whether the specific object has the inductive heating property. Thus, when the user simply places the loaded object on the device, the device may allow the user to quickly and intuitively confirm whether the corresponding loaded object has the inductive heating property.

Abstract: The induction heating apparatus includes a current conversion circuit, a first working coil whose one end is connected to the current conversion circuit, a second working coil whose one end is connected to the current conversion circuit or the other end of the first working coil, a working coil base that accommodates the first working coil and the second working coil, a resonance capacitor that connects to the other end of the second working coil, a first relay that adjusts a connection between the other end of the first working coil and the resonance capacitor, a second relay that selectively connects one end of the second working coil to any one of the other end of the first working coil and the current conversion circuit, and a controller that controls the first relay's and the second relay's connections.
