Cooking apparatus and method for controlling the same

A cooking apparatus comprising:

• a plurality of induction heating coils including a first heating coil and a second heating coil that are concentric and form a high power burner, a third heating coil and a fourth heating coil of the plurality of induction heating coils forming low power burners;
• a power supply unit that includes a first power supply unit and a second power supply unit which have a different phase from each other;
• a switching unit that performs a switching so that at least one of power supplied by the first power supply unit and power supplied by the second power supply unit is selectively provided to the first heating coil and the other one is selectively provided to the second heating coil, the third heating coil, and the fourth heating coil;
• and
• a control unit that controls the coil driving unit to distribute the power supplied by the second AC power supply unit and to selectively provide the distributed power to the second heating coil, the third heating coil and the fourth heating coil, and controls the coil driving unit to distribute the power supplied by the second AC power supply unit to one heating coil having a priority among the second heating coil, the third heating coil and the fourth heating coil.

A cooking apparatus comprising:

• a plurality of induction heating coils including a first heating coil and a second heating coil that are concentric and form a high power burner, a third heating coil and a fourth heating coil of the plurality of induction heating coils forming low power burners;
• a first substrate including a first alternating current (AC) power supply unit to supply a first AC power;
• a second substrate including a second AC power supply unit to supply a second AC power having a different phase from that of the supplied first AC power supply unit;
• a switching unit that includes a substrate physically separable from the first substrate and the second substrate, that switches at least one of the supplied first AC power and the supplied second AC power each transmitted from at least one of the first substrate and the second substrate, and that selectively transmits the switched supplied AC power to the first heating coil, the second heating coil, the third heating coil, and the fourth heating coil;
• and
• a control unit that controls the coil driving unit to distribute the power supplied by the second AC power supply unit and to selectively provide the distributed power to the second heating coil, the third heating coil and the fourth heating coil, and controls the coil driving unit to distribute the power supplied by the second AC power supply unit to one heating coil having a priority among the second heating coil, the third heating coil and the fourth heating coil.

• a first alternating current (AC) power supply unit to output a first AC;
• a second AC power supply unit to output a second AC of a different phase from that of the first AC;
• a switching unit that selectively transmits the outputted first AC and the outputted second AC to the first heating coil and the second heating coil, while transmitting the outputted first AC to the first heating coil and distributing and selectively transmitting the outputted second AC to the third heating coil and the fourth heating coil;
• and
• a control unit that controls the coil driving unit to distribute the power supplied by the second AC power supply unit and to selectively provide the distributed power to the second heating coil, the third heating coil and the fourth heating coil, and controls the coil driving unit to distribute the power supplied by the second AC power supply unit to one heating coil having a priority among the second heating coil, the third heating coil and the fourth heating coil.
