ABSTRACT:
In an electric hotplate (1) a hotplate body (2) is constructed in such a way that a holding element (25) provided to fix the hotplate in a hob and arranged below the hotplate can be located in a relatively small distance from the top-side respective the cooking surface (3) of the hotplate body (2). Thereby a very flat mounting arrangement is possible. For example an outer flange rim (6) of the hotplate body (2) can have a groove-like reception depression (30) for an engagement of the holding element (25), this engagement also serving a rotation prevention. It is also possible to construct the outer flange rim extremely low, e.g. in such a way that its lower edge face is located higher than the lower edge face of a central stud of the hotplate body.
