Patent ID: 11040598

Abstract:
The induction heater and a method for controlling overheating of an induction heater, and to an induction heater in which overheating of a heating element may be prevented by allowing a coolant to be introduced from a lower side, flow upwardly while being in contact with the heating element, and be then discharged to an upper side to improve air bubble discharge performance of the coolant, in the induction heater heating a heating element in an induction heating manner. In addition, the present invention relates to an induction heater and a method for controlling overheating of an induction heater in which a fault of the induction heater or a fire due to overheating may be prevented by deciding whether or not a heating element is overheated using one or more of a current sensing means and a temperature sensing means capable of sensing overheating of the heating element and performing a control to supply power to an induction coil or block power supplied to the induction coil depending on a decision result.
