PROBLEM TO BE SOLVED: To reduce the steam rising from an opening portion of a front face when an user opens a door. SOLUTION: An option duct 91 is partitioned into an air sucking/discharging chamber 96 and an air discharging chamber 97 by partitioning plates 98, 99 and a fan receiving portion 100, and the air discharge chamber 97 is provided with a steam receiving portion 101 disposed in a state of covering a first air discharge port 66 and provided with an opening/closing door 102 at its front part. An air discharge fan 95 is rotated forward in the air discharging direction in heating cooking, to push and open the opening/closing door 102 from a first air discharge port 66, and discharge the steam entering into the air discharge chamber 97 from a heating chamber 20 to a front part from a sucking/discharge port 92. Further it is rotated backward in the air sucking direction when the door 12 is released, the steam rising from an opening portion of the heating chamber 20 is sucked from the sucking/discharging port 92 of the option duct 91, and discharged from discharging ports 93, 94 of front both sides. Accordingly, the steam rising from the opening portion of the heating chamber 20 can be reduced when the door 12 is opened. COPYRIGHT: (C)2009,JPO&INPIT
