ABSTRACT:
A microwave oven includes a body which defines an appearance of the microwave oven, a cooking cavity provided therein, a microwave-supplying unit which generates microwaves to irradiate the microwaves into the cooking cavity, a plurality of vent holes which are formed on a sidewall of the cooking cavity to ventilate the cooking cavity, a water collecting depression which is formed on a bottom of the cooking cavity to contain water therein to generate steam, and a vent hole control unit which selectively closes the vent holes. During a steam cleaning operation of the microwave oven, the vent holes are closed to prevent a leakage of the steam from the cooking cavity to the outside of the microwave oven.
