Abstract: A cooker, a method for controlling power of a cooker, and a power control system including the same are provided. A high power cooking device can be used without making an additional power construction work or causing a power circuit breaker installed in an input terminal of a household power source to be opened. Driving power of a burner is controlled or distributed by using a current flowing in a power circuit breaker or an overcurrent breaker installed in a load end, whereby power operation efficiency of an input power source can be enhanced and the input power source cannot be broken.

Abstract: The present disclosure relates to a cooking apparatus having a heating module capable of moving in a two-dimensional space and, particularly, to a cooking apparatus comprising: an upper plate configured to support a cooking vessel, a heating module disposed movably in a space provided under the upper plate and included a coil, and a rail disposed under the heating module to guide movements of the heating module, wherein electric current is supplied to the rail and the heating module supplies an alternating current through the rail. According to the present disclosure, the heating module supplies a current through the rail rather than receiving a current through a separate connection coil or wiring from an external power supply, thereby enabling shorting or disconnection of a current to be prevented even if the heating module moves.

Abstract: An induction heating cooking apparatus and a control method thereof are provided. A vessel can be effectively heated by using a plurality of heating coils regardless of a position of the vessel. By connecting a plurality of heating coils to a smaller amount of inverters through relays, only a heating coil on which a vessel is placed, among the plurality of heating coils, can be heated. Also, by connecting the heating coils in series, a current flowing in the heating coil can be lowered, and thus, a rated current of the inverter can be lowered. Also, by connecting relays and heating coils such that a larger amount of heating coils are operated, while minimizing the amount of inverters, manufacturing cost can be reduced, operation efficiency can be increased, and stability of the cooking apparatus can be enhanced.
