Abstract
A microwave oven includes a power supplying part, a cooking chamber, a door of the cooking chamber, a magnetron, and high and low voltage generating parts supplying voltage to the magnetron, further including: a door switch installed on branch lines of a power line toward the high and low voltage generating parts, operating depending on opening and closing the door and selectively connecting the power supplying part with the high and low voltage generating parts; a power saving switch controlling a connection between the power supplying part and the low voltage generating part; and a controller switching off the power saving switch when a predetermined time elapses after the magnetron stops operating. With this configuration, in the microwave oven, a power saving function can be automatically selected, and automatically suspended when the door is opened.
