ABSTRACT:
In the case of an electric hotplate (1), the profile ring (17) for supporting on the hob (2) is provided by an elastically resilient circumferential stretching and a resilient cross-sectional zone (29) with an outer ring leg (18) resiliently deflectable within close tolerances and which by a washer-like circular rim (28) forms a flat support surface (26) for support on the hob (2). The consequently cup springlike, movable seat part (25) of profile ring (17), on securing the electric hotplate (1), slides with a sliding edge (27) out of an angular position into a whole-area engagement on seat (8) of hob (2).
