PROBLEM TO BE SOLVED: To provide a high frequency heating device in which a high voltage capacitor for driving a magnetron is covered and a magnetron cooling fan is connected with an air intake to serve as an air guide, thereby achieving cost reduction by means of a reduction in the number of components and assembly man-hours and enabling the efficient cooling capability.SOLUTION: The device includes a fan 17 for cooling the magnetron; and the high voltage capacitor 18 for driving the magnetron. In an insulating cover 20, one end is opened in the vicinity of the air intake 19 and the other end is opened in the vicinity of the fan 17 for cooling the magnetron, and the insulating cover leads air sucked from the air intake 19 to the fan 17 for cooling the magnetron through the vicinity of the high voltage capacitor 18 for driving the magnetron with the fan 17 for cooling the magnetron. As a result, the insulation between a body casing 21 and the high voltage capacitor 18 for driving the magnetron is ensured, and the high voltage capacitor 18 for driving the magnetron can be cooled. |
