Air circulation structure for microwave oven

Abstract

An air circulation structure for a microwave oven is disclosed. The structure includes a fan for sucking air into the interior of a machinery compartment installed below a cooking chamber of the microwave oven, a bottom plate having an air suction port through which an air sucked by the fan and radiating heat generated from the electrical elements of the microwave oven is flown into the interior of the cooking chamber, and a rear surface plate having a first air discharge port through which the air passed through an air suction port formed on the bottom plate and circulated in the interior of the cooking chamber is discharged to the outside of the microwave oven, for thereby effectively radiating heat from electrical elements of a microwave oven having a machinery chamber installed below a cooking chamber and dehumidifying from the interior of the cooking chamber.
