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.
