<p><P>PROBLEM TO BE SOLVED: To aim at the improvement of cooling efficiency and the reduction of the number of assembly man-hour through the improvement of a ventilation structure of an electromagnetic cooking device. <P>SOLUTION: In the electromagnetic cooking device having a heating coil 2, an inverter circuit 3 driving the heating coil 2, and a motor fan unit 4 circulating cooling air to them equipped inside an outer case 1, the inverter circuit 3 and the motor fan unit 4 are to be housed in a blocked case 15 having an inlet opening 16 and outlet opening 17 of the cooling air, and the case 15 is to be inserted into the outer case 1. A wind channel 5 sealed by the blocked case 15 is formed between the inlet opening 16 and the outlet opening 17, which enhances the cooling efficiency of the inverter circuit 3 through prevention of wind leak. Further, an assembly work can be made simple by building the inverter circuit 3 and the motor fan unit 4 into the case 15 outside the outer case 1 and inserting the case 15 into the outer case 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
