Abstract: An electric oven capable of cooking food in a cook-top way. The electric oven according to the present invention includes a cabinet which forms an appearance of the electric oven, a cooking cavity defined inside the cabinet and having an opening front part to contain food therein, and a heater movably mounted in the cooking cavity and moves forward from the cooking cavity through the opening front part so as to cook food in cook-top way. The heater may heat the inner part of the cooking cavity also so as to cook food in a conventional oven-cooking manner.

Abstract: A heating cooker produces hot steam by boiling water in a cooking cavity thereof, and cooks food by use of the hot steam to prepare steamed food. The heating cooker has a cabinet to define a cooking cavity therein. A steaming vessel to contain food and water therein, is laid on a bottom wall of the cooking cavity. A heater is provided at the bottom wall of the cooking cavity to heat the bottom wall of the cooking cavity on which the steaming vessel is laid. Thus, the heater heats the water contained in the steaming vessel, so that the water is boiled to produce the hot steam.

Abstract: A surge current prevention circuit of a microwave oven, where a surge relay is turned on or turned off by a predetermined DC voltage supplied by rectification of a predetermined low voltage, such that cost of parts of the surge current prevention circuit becomes low to thereby reduce the manufacturing cost, and electricity can be decreased and operation of the microwave oven can be stabilized by the constant switching operation time of the surge relay.

Abstract: A microwave oven includes a magnetron for performing a microwave cooking function, and a separate electric heater element for performing a grilling function. A single control knob on a control panel serves to activate the magnetron and heater element, as well as selecting an output power of the magnetron. By actuating that single knob a user can select cooking operations solely by microwaves only, or solely by the heating element, or by a combination of both. A separate knob on the control panel enables a cooking time to be selected.
