Abstract
A hotplate has on the bottom of its hotplate body (11) a cover plate (15), through which is passed an electric conductor (18) mounted in an insulating bushing (19) and which only slightly projects over the end of the insulating bushing (19). For automatically placing the hotplate in a stove unit, electrical connecting lines (21) are guided by a positioning member (20) which can be fixed to the rim (14) of the hotplate body (11). On the inside, the connecting lines project far enough to be brought into contact with the electrical conductor (18) passing through the cover plate.
Claims18
An electric hotplate having electric heating elements adapted for automatic connection to electric power connecting lines, the hotplate comprising:
- a hotplate body of highly thermally conductive material, the electric heating elements being positioned and secured to a bottom surface of the hotplate body and electrically insulated therefrom;
- a lower cover plate attached on the underside of the hotplate body;
- an electrically insulating mounting member arranged in a marginal region of the hotplate, the insulating member extending through the lower cover plate and carrying electric hotplate terminal lines from the heating elements in spaced relation, the terminal lines having stubs projecting from the insulating member;
- and,
- an electrically insulated positioning member for engaging the electric connecting lines and holding portions of the connecting lines at predetermined positions to ensure contact between the stubs and the portions, respectively, to facilitate automatic connection of respective stubs and portions to one another, the electrically insulating positioning member being a high temperature material, mounted on at least one of the lower cover plate and a peripheral extending rim of the hotplate body and being at least partly supported by the rim, the positioning member being shaped to engage the rim.
