Abstract:
A microwave oven, comprising:a main body forming a cooking chamber for the microwave oven; a door for selectively opening and closing the cooking chamber; a magetron for performing cooking by the microwave oven; a power supplying part for supplying electric power to the microwave oven; a high voltage generating part for connection with the power supplying part for supplying a voltage to the magnetron; a low voltage generating part for connection with the power supplying part for supplying a voltage to at least one device of the microwave oven; a door switch for selectively connecting the power supplying part with one of the low voltage generating part and the high voltage generating part, the door switch selectively connecting the power supplying part with the low voltage generating part when the door is open and the door switch selectively connecting the power supplying part with the high voltage generating part when the door is closed; a power saving switch for selectively controlling a connection of the power supplying part with the low voltage generating part; and a controller for selectively switching on and off the power saving switch, the controller for switching off the power saving switch and for cutting off the electric power supplied to the low voltage generating part when a predetermined period of time elapses after the magnetron stops operating when the door is closed.
