PURPOSE:To prevent the trouble of respective cookers by a constitution wherein respective control units are cooled by the primary combustion air for a gas range while the outer casing of the gas range is cooled by the secondary combustion air for the same in the cooking device having a plurality of heating cookers such as the gas range and a high frequency heating device or the like. CONSTITUTION:The exhaust gas of a heating chamber 32 for the high frequency heating device 7 is exhausted from an exhaust tube 31 to an exhaust port 6. Air inducted from a suction port 33 cools a high frequency generating device 24 and is discharged through an exhaust duct 30, an exhaust passageway 21 and the exhaust port 6. the primary combustion air for the gas range 2 which is induced from a suction port 26 cools the control unit 25 for the high frequency generating device 24, then, cools the control unit 16 through an air passageway 22, an open port 27 and a suction air passageway 18 and, thereafter, is supplied to the mixing tube 13 for a burner 5. The secondary air is supplied to the air passageway 22, an introducing port 28 and an air passageway 19 and, then, to the burner 5 after cooling the outer casing of the gas range 2. Thus, the trouble of the heating cooker may be prevented by cooling respective control units and the heaters. |
