A protective cover for a microwave oven prevents water from permeating the inside of the oven through venting holes, and also prevents insertion of foreign materials into the holes. The convection microwave oven includes an inner case 10 forming a cooking chamber 100, and an outer case 20 coupled to the inner case 10. A duct 50 is mounted on the rear plate 12 of the inner case 10. To an inside of the duct 50, a blower fan 61 is installed, and to the outside of the duct 50, a cooling fan 71 and a motor 63 are installed, these being covered by the protective cover 80. The protective cover 80 includes a central surface 81, top and bottom surfaces 82 and 85, and right and left surfaces 83 and 84. Exhaust holes 80b on the top surface 82 have outward guide projections 82a for preventing dripping water on the top surface 82 from entering the inside, and intake holes 80a on the central surface 81 have inward guide projections 81a for preventing foreign materials from penetrating into the inside. <IMAGE> |
