ABSTRACT:
A microwave oven includes a magnetron, a blower fan system, and a gas sensor for detecting an exhaustion gas concentration developed from an oven cavity. When the exhaustion gas concentration exceeds a preselected value while an actual cooking operation is conducted, the gas sensor develops a first detection output to complete the actual cooking operation. While the actual cooking operation is not conducted, the gas sensor functions as a gas leak alarm sensor. When an ambience gas concentration shows an abnormal value, the gas sensor develops a second detection output to announce a dangerous gas leakage. While the actual cooking operation is not conducted, the blower fan system is intermittently energized to introduce the ambience air toward the gas sensor for monitoring purposes.
