<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooking device capable of effectively cooling an IH coil part while cooling inverter circuit components at the same time. <P>SOLUTION: Cooling chambers 8R, 8L extended in a longitudinal direction in right and left side spaces of a grill heating chamber 9 and isolated from the grill heating chamber 9 are formed inside a body part A. A fan case 37 provided with a blower inside, and a component case 34 storing a circuit board 41, are arranged in series in the respective cooling chambers, and cooling air exhausted from an exhaust port 37C of the fan case 37 is led into the component case 34. A cooling duct 42 formed with a blowoff hole 42C in the upper face to blow off cooling air toward heating coils 6RC, 6LC is arranged below the heating coils, and the cooling duct 42 communicates with the exhaust port 37C of the fan case 37 to lead the cooling air to the inside. The cooling air diverges into at least two air courses at the stage of the component case 34 and is supplied to the heating coils 6RC, 6LC to cool them. The cooling air before cooling the circuit board 41 is used as the cooling air on one side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
