PURPOSE:To reduce the number of parts by providing a blocking body which is formed as one body with the free to be bent into the grill installed at a front gas discharge section and blocks the front gas discharge section when an outdoor gas discharge section is selected. CONSTITUTION:The smoke that rises from below a microwave oven is discharged from a selected route out of a first, second, and third routes. If the selected route is the first route, the sucked smoke is discharged to the front side of the microwave even. If it is the second route, the smoke is discharged upwards. If it is the third route, the smoke goes backwards. A fourth grill 13 is formed with resin as one body, and it has a structure that allows its mounting and dismounting as desired. And, a pair of freely bendable blocking bodies 40 and 41 are formed as one body in the vertical direction. Such blocking bodies 40 and 41 are engaged respectively with an engaging section 43 formed on the outer ceiling plate 42 of the microwave oven and an engaging section 45 formed on the upper piece 44, and a front gas discharge port 12 is opened to discharge the gas toward the front side. On the other hand When the second route and third route are selected, the sections 40 and 41 are bent like the broken lines in the figure and they are mutually connected by screws 46 so that the front gas discharge port 12 is closed.
