ABSTRACT:
A high frequency heating apparatus has an oven-defining structure having an access opening in communication with a heating chamber defined therein, and a hingedly supported metallic door for selectively opening and closing over the access opening. The door has its peripheral area formed with a groove open towards the heating chamber. The bottom of the groove is situated frontwardly of the door with respect to the apparatus. An outerside wall extending from the groove is formed with a plurality of cutouts and a plurality of generally rectangular openings alternating with the cutouts. Each of the cutouts and each of the rectangular openings have one edge positioned on one side of a setup portion, protruding from the bottom of the groove, adjacent the oven-defining structure. The outer wall has a portion bent to protrude transversely into the groove to define a partitioning wall.
