摘要： 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.
摘要翻译：提供感应加热烹调设备及其控制方法。无论容器的位置如何，都可以通过使用多个加热线圈来有效地加热容器。通过将多个加热线圈通过继电器连接到较小量的逆变器，可以加热多个加热线圈中仅容纳有容器的加热线圈。此外，通过串联连接加热线圈，能够降低在加热线圈中流动的电流，能够降低逆变器的额定电流。此外，通过连接继电器和加热线圈，使得操作更多量的加热线圈，同时使逆变器的数量最小化，可以降低制造成本，可以提高操作效率，并且可以提高烹饪装置的稳定性。
