ABSTRACT:
A microwave oven includes a control panel having a panel casing, a membrane board, and a cover sheet. The membrane board is mounted to a front surface of the panel casing. A membrane board seat is formed at a predetermined area of the front surface of the panel casing so as to seat the membrane board. The control panel further includes an air discharging channel which is provided on the membrane board seat, and discharges air existing between the membrane board seat and the membrane board. The air discharging channel may extend to a cover sheet-panel casing interface. Accordingly, air existing between the panel casing, the membrane board and the cover sheet is discharged to the outside as the panel casing, the membrane board and the cover sheet are attached to each other.
