Abstract
A combined microwave and electric heating oven includes a magnetron for microwave cooking purposes, and a heater for electric heating cooking purposes. A gas sensor is disposed in an exhaustion duct for detecting concentration of a gas developed from an oven cavity, and a thermistor is secured to an oven wall for detecting an air temperature within the oven cavity. A programmed automatic cooking control system is provided for first activating the magnetron. When the gas sensor output reaches a preselected value, the magnetron energization is terminated and, then, the heater is energized. Power supply to the heater is controlled in response to an output signal derived from the thermistor.
