Abstract
A microwave oven includes a heating chamber containing a magnetron for heating and cooking food S, a body with a door provided in front of the heating chamber, and a control circuitry provided on the body for controlling driving of the magnetron. The control circuitry includes a switch key for switching either to a cooking time input mode for setting and inputting time period for driving magnetron or to an optional timer input mode for setting and inputting time period for an optional timer, input ten keys for inputting the time period of the set input mode, a timer body for separately counting time periods of respective input modes input by the ten keys, a display portion for displaying time count of either one of the input modes switched by the switch key, and a start key for starting time count for the input time period on display portion. When the operation is switched to the optional timer input mode by switch key 22 and an input of the time period for the optional timer is given through ten keys, time count of the time period for the optional timer starts after a prescribed time period, without waiting for an input to start time count from the start key.
