A magnetron for a microwave oven is provided that decreases noise in an ISM band by minimizing a size of a lower end shield, and thus, minimizing EMI generation. In the magnetron for the microwave oven, as a midpoint of a side lead hole is positioned inside a virtual circle formed by points positioned at a predetermined distance from a midpoint of the shield disc and a side lead is connected in a straight line, there are advantages that a further bending process is not generated and a defective rate that occurs in the manufacturing process of the shield disc may be decreased.

Magnetron for microwave oven

Provided herein are a cooking apparatus and an operating method thereof. The cooking apparatus includes a cavity, a microwave generator to generate and output microwaves of a plurality of frequencies to heat an object within the cavity, and a controller to calculate interpolated microwave frequencies for a heating session, based on microwave frequencies calculated during a scanning session, and to calculate heating times of the interpolated microwave frequencies. Thereby, operating efficiency of the cooking apparatus is improved.

Cooking apparatus and operating method thereof

Provided herein are a door choke and a cooking apparatus including the same. The cooking apparatus includes a front plate forming the front surface of a cavity, a door to open and close the cavity, and a door choke including a first attachment member attached to the door and including at least two bent parts and a second attachment member attached to the door and including at least two bent parts so as to be separated from the first attachment member to form a space, and a bending direction of the first attachment member and a bending direction of the second attachment member are opposite to each other. Thereby, effective electromagnetic interference shielding is achieved.
