  • Patent number: 6864468
    Abstract: Disclosed is an electric oven which increases temperature fast and reduces heat loss in accordance with that a cavity surface generates its own heat by using an induction heating. The electric oven comprises: a case having a door at a front side and having a cavity for receiving food therein; a magnetron installed at one side of an upper portion of the cavity for generating microwave of high frequency and supplying heat to the cavity; an inverter for generating high frequency at a space between the case and the cavity; first, second, third, and fourth heating units installed each side of the cavity for supplying heat. Since temperature of a cooking chamber can be set as wanted uniformly and faster, preheating time and actual cooking time can be reduced. Also, since inner temperature of the cavity rises faster and simultaneously, an automatic cleaning in the cavity using pyrolysis can be performed faster and uniformly, thereby reducing power consumption.
