ABSTRACT:
A high-frequency heating apparatus includes an outer enclosure, a high voltage generator such as a high-voltage capacitor, and an air guide, wherein the air guide is provided with a plastic hinge formed by partially reducing a wall thickness thereof. The invented structure can bend the plastic hinge to locate an end flap of air guide in a space between a terminal of the high-voltage capacitor and the outer enclosure defining a dead metal part, to easily ensure electrical insulation between the terminal and the outer enclosure without dependent on variations in quality of workmanship in the manufacturing process. In addition, it can reduce a number of working processes as well as amount of waste since all it requires is to bend the plastic hinge to provide the electrical insulation.
