Provided herein are a cooking apparatus. The cooking apparatus includes a cavity, and a microwave generator to generate and output microwaves of a plurality of frequencies to heat an object within the cavity, wherein the microwave generator includes a controller to calculate heating efficiencies based on microwaves reflected by the inside of the cavity from among the output microwaves and to calculate heating modes consisting of microwaves for heating, during a scanning session and to control the heating modes so as to achieve the equal heating time during a heating session. Thereby, the object within the cavity is uniformly heated.

Cooking apparatus and operating method thereof

Provided herein is a cooking apparatus. The cooking apparatus includes a plate forming a cavity, a microwave transmission line to transmit microwaves to the inside of the cavity, and a first metal part connected to one end of the microwave transmission line and extended in one direction so as to be parallel with the plate. Thereby, an antenna having improved efficiency is provided.

Cooking apparatus

An enamel coating including a phosphate-based ingredient is provided on an inner surface of a cooking chamber and the inner surface of the cooking chamber is cleaned using high-temperature cleaning water. Therefore, the cleaning of the cooking chamber can be performed more efficiently.

Cooker

An electric oven has an air passage structure that is designed to effectively cool down electric components. The air passage structure quickly cools down a variety of electric components on a top surface of a cavity using air introduced from outside the oven. The oven has a series of passages and openings allowing the effective movement of air past the electric components and through the oven.

Electric oven

A cooling and exhaust system of a dual oven has upper and lower ovens, in which, in one aspect, an installation structure of a cooling fan and an exhaust structure provided for respectively cooling and exhausting the upper and lower ovens may be integrated into a simplified structure having common components to increase the manufacturing productivity. In another aspect, fans provided at the upper and lower ovens may be independently controlled to operate at different speeds according to a desired operation to maximize the cooling efficiency.

Cooling and exhaust system of dual electric oven

A electric oven is provided that includes a body, a cooking chamber located within the body for receiving food, the cooking chamber having an upper surface, a lower surface, and a rear surface joining the upper surface to the lower surface, at least one of a convection heater located at the rear surface of the cooking chamber and a bake heater located at the lower surface of the cooking chamber, and at least two broil heaters located at the upper surface of the cooking chamber, each of the at least two broil heaters being individually operable. Methods for preheating the electric oven are also provided.

Electric oven with multiple broil heaters and method for preheating the electric oven

An electric oven includes a housing having a cooking chamber for cooking food and a component chamber containing components for operating the electric oven. A door is provided on a front of the housing for selectively opening and closing the cooking chamber. A suction duct introduces external air from outside of the housing into the component chamber, and an exhaust duct with a sloped portion discharges air from the component chamber to outside of the housing.

An electric oven includes an oven body, a first convection system having a first convection heater and a first convection fan that are installed in the oven body to operate for a first space in the oven body, and a second convection system having a second convection heater and a second convection fan that are installed in the oven body to operate for a second space in the oven body. Further, the first and second convection fans are driven by a single common driving unit.

Electric oven and method of operating the same

A cooling apparatus of a cooking appliance including a cabinet having a cooking chamber located therein and an electric component chamber located outside the cooking chamber; a door installed on the cabinet for opening and closing the cooking chamber, and having a suction channel and a discharge channel communicating with the electric component chamber; and an air blower installed in the electric component chamber for sucking air to the inside of the electric component chamber through the suction channel and the discharge channel of the door and discharging the air, so that the external air having a low temperature is directly sucked through the door, cools the electric component chamber, and is then discharged to the outside, thereby increasing cooling efficiency of the door.

Cooling apparatus of cooking appliance

A cooling apparatus of a cooking appliance including a cabinet having a cooking chamber located therein and an electric component chamber located outside the cooking chamber; a door installed on the cabinet for opening and closing the cooking chamber, and having channels so as to cause external air to flow into the electric component chamber and a part of the air to flow into the electric component chamber via side surfaces of the cooking chamber; and an air blower installed in the electric component chamber for forcibly sucking in the external air and discharging air having cooled the door and the electric component chamber, thereby improving cooling efficiency of the door and the inside of the electric component chamber.
