ABSTRACT:
A microwave oven includes a cooking chamber and an electronic component compartment separated from one another by a partition wall. Air inlet holes are formed in an upper portion of the partition wall, and air outlet holes are formed in another wall of the cooking chamber to enable air to be circulated through the cooking chamber by a fan disposed in the electrical component compartment. First drain holes are formed in a lower portion of the partition wall diagonally opposite the air inlet holes to enable condensed moisture formed in the cooking chamber to drain into the electrical component compartment. That moisture exits the electrical component chamber through second drain holes formed in the floor of the electrical component compartment. A barrier is disposed in the electrical component compartment to surround the first and second drain holes, thereby preventing moisture from reaching any of the electrical components.
