ABSTRACT:
An electric hotplate, particularly intended for continuous operation in commercial use, is provided on the bottom surface with at least two superimposed reflectors (24, 28), which in each case form the lower boundary of an insulating zone (29, 30) and while incorporating an outer flange edge (4) of hotplate (2) seal the bottom surface thereof. This leads to a very low no-load power of the electric hotplate with a very rapid response to a higher power setting.
