Abstract (en)

[origin: ES269068U] An electric hotplate (11) has a metal plate-like or inverted dish-shaped circular hotplate member (12) against whose bottom are pressed by spring elements (25) thin flexible tubular heaters (31), while interposing a multilayer insulation (28). A support disk (26) is placed between insulation (28) and spring elements (25). According to a variant a reinforcement is provided, which may also be placed between the insulation and the tubular heaters. The electric hotplate has a low heat storing capacity and a very flat upper cooking surface (32), even under operating conditions.
