Abstract
An electrical oven and method of controlling the same includes a heater heating unit to heat food using an electric heater; an induction heating unit to heat the food using a high-frequency current, and a control unit to drive the heater heating unit and the induction heating unit simultaneously in a preheating cooking mode. The electric oven of the present invention carries out heating by the electric heater and induction heating by high-frequency current, so preheating time required for an inner temperature of a cooking cavity to reach a preheating temperature is decreased, thereby reducing a total cooking time.
