PURPOSE:To prevent microwaves from leaking from a sensor hole while food is heated by microwaves, and to prevent an object lens from being smeared by steam and oily smoke during heating, by providing a shutter which opens the sensor hole when a sensor is detecting the state of food, as well as to shut off the sensor hole when it does not detect food, in a grill oven range. CONSTITUTION:When a sensor is sensing, a shutter 22 is positioned on the left side by the tension of a spring 104, with a sensor hole 21 being open. When food is heated to be cooked, a plunger 100 is extended by an energized electromagnetic solenoid 23. Then the shutter 22 is slid between the sensor hole 21 and an object lens 19 by a connecting part 101 against the tension of a spring 104, and the sensor hole 21 is shut off. With such an arrangement, oily smoke and steam from food is prevented from getting into a sensing unit through the sensor hole at the time of heating, so that the object lens 19 is prevented from being smeared. |
