Abstract
An electric hotplate with a cast hotplate member has a downwardly-directed border on its outer periphery. The edge of a covering sheet centrally fixed to the hot plate by a hollow screw rests on the lower edge of the border. A covering sheet step is centered within the border. A moisture-proof closure is obtained through an interposed seal and insulation is provided by crinkled aluminum foil. The hot plate connecting leads are passed via an insulating member through the covering sheet which, peripherally displaced by 180.degree., faces a depression in the covering sheet, so that hot plates according to the invention can be stacked in a space-saving manner. The connecting leads are flexible and their ends are brought together in a common connecting member.
