And a plurality of through holes 39 formed in 38. In addition, the plurality of through holes 40 formed in the upper surface of the cooking chamber 21 and the air flowing through the through holes 40 are exhaust fan 50 so that the air in the cooking chamber 21 flows toward the exhaust fan 50. It includes a flow path formed through the guide duct 41 installed on the cooking chamber 21 so as to be guided smoothly toward).

In addition, the exhaust port 42 is formed in the upper rear portion of the main body 20 so that the air sucked through the exhaust passage and the cooling ventilation passage may be discharged to the outside by the operation of the exhaust fan 50. Although not shown in the figure, the exhaust port 42 is provided with a normal external duct for guiding the air discharged through the exhaust port 42 to the outside of the building.

In addition, the exhaust fan 50 sucks the air from the first exhaust fan 51 installed on the upper passage 33 side of the exhaust passage and the cooling ventilation passage so as to suck the air from the exhaust passage to the outside and discharges it to the outside. The second exhaust fan 52 is installed on the side of the guide duct 41 to form a cooling ventilation flow path, and between the two exhaust fans (51, 52) to rotate the two exhaust fans (51, 52) at the same time And a motor 53. That is, the two exhaust fans 51 and 52 spaced apart from each other are rotated at the same time by being coupled to the rotation shaft 54 extending to both sides of the motor 53.

At this time, the two exhaust fans (51, 52) is composed of a conventional multi-purpose centrifugal fan that sucks air into the center and discharges it in the radial direction, and the air discharged in the radial direction on the outer surface of each exhaust fan (51, 52) A conventional fan casing 55 is installed to be guided toward the exhaust port 42.

The exhaust fan 50 is configured to exhaust the gas oven side through the first exhaust fan 51 and to cool the electric chamber 22 and ventilate the cooking chamber 21 through the second exhaust fan 52.
