ABSTRACT:
A microwave oven having a heater and a wall structure, includes a heater cover disposed between the heater and the wall structure and a plurality of protruding portions formed on the heater cover and on a depressed portion of the wall structure, respectively. The heater cover includes a bent portion formed at its peripheral edge, and a hanger, for hanging the heater, is fixed to the heater cover to prevent the heat transfer in every direction from the heater. In addition, the protruding portions are brought into contact with each other and are fixed by rivets. The microwave oven further includes an air conduit for guiding an air flow produced by a fan to a space between the wall structure and the heater cover.
