Abstract
This invention discloses an improved safety device for microwave oven having one thermostat commonly preventing possible overheat of the cavity and magnetron of the microwave oven. The thermostat is placed in a position suitable for sensing both a peripheral temperature of a magnetron and a temperature of an air exhausted from a heating cavity through an air exhaust port. The thermostat cuts off the outside electric power for the microwave oven when the peripheral temperature of the magnetron or the temperature of the exhaust air coming out of the heating cavity is higher than a predetermined allowable temperature. The air exhaust port is provided about the magnetron. The thermostat mounting bracket is connected to the magnetron mounting bracket.
