ABSTRACT:
The present invention provides a high frequency heating apparatus having a structure, which can be mounted/dismounted an air-exhausting grill without any tools. In this apparatus, an air-exhausting grill is arranged by that a fixing claw portion having a bent Z-shape, a fixing hooking portion having a concave notch, and a magneto joint plate are arranged, whereas a main body located opposite to the air-exhausting grill is arranged by that a slit hole, a hooking flange, and a magneto fixing plate are arranged. As a result, since the magneto joint plate is absorbed with the magneto fixing plate to be fixed with each other, the mounting/dismounting work capability of the air-exhausting grill can be improved without using the tool in a simple manner, and furthermore, a clean cooking appliance can be secured, while the cooking appliance can be readily cleaned.
