Definitions

  • CH-A-187 383 Electric hot plates according to the preamble of claim 1 have become known from CH-A-187 383. These are circular hot plates with a cast body, which consist of separate or connected, heated rings. CH-A-187 383 shows the connection of these rings by means of a sheet metal strip with an expansion bead.
  • an electric hotplate which has an oval shape in plan view and a common heating with inserted electrical heating resistors on its underside. They are used to heat elongated cooking or roasting dishes.
  • FR-A-2 448 693 describes a radiant heater for heating a glass ceramic plate. It consists of a round radiant heating field, which is separated by a web from an adjoining crescent-shaped field, so that an oval field consisting of two heating zones of different sizes is created. With radiant heaters of this type, which work together with a glass ceramic plate running over several cooktops, heating zones of this type which can be switched differently pose no problems. Glass ceramic cooking appliances are, however, generally much more complex and inferior to the cast-iron hot plates in many of their properties.
  • the object of the invention is to provide an electric hotplate made of cast material which is more flexible with regard to the adaptation to different cooking vessels and tasks and which, with a sufficient service life, enables good efficiency.
  • the intermediate area between the two heating zones particularly preferably consists of relatively thick cast material, so that there is no need to fear any warpage of the cast body in this area.
  • an electric hotplate 11 which has a hotplate body 12, which consists of cast material, namely of cast iron.
  • the hotplate body is made from a common cast body, which has the elongated shape shown in FIGS. 1 and 2, and is composed in plan view of two equal-sized arcs and straight lines connecting them.
  • the length corresponds to approximately twice the diameter of the circle plus approx. 1 to 3 cm.
  • the hotplate body is constructed like two circular hotplates arranged next to one another with a double concave intermediate area 24 which connects the two circular heating zones 17, 18 to one another.
  • the zones 17, 18 are identical, but mirror images of each other, and have a common upper flat cooking surface 15.
  • heating resistors 22 are embedded in an insulating investment material in spiral grooves 21, each of which occupies a heating ring region 19, which forms an unheated central zone 20 surrounds.
  • Each circular heating ring region 19 is surrounded by a downward-facing edge 23, to which a projecting flange 35 is connected in the upper outer part.
  • the intermediate area 24 between the two heating zones 17, 18 is plate-shaped and consists of relatively thick cast material of approximately 10 mm thickness, the minimum distance between the edges 23 is 1 to 3 cm (dimension a).
  • An outer section that is inclined outwards and downwards usually reaches over one upstanding edge of a mounting plate and is supported on this. This enables a dense installation of the hotplate.
  • each heating zone there is a temperature limiter 33 which senses the temperature of the hotplate and protects each of the hotplate halves independently of one another against excess temperature.
  • the hotplate is also controlled or regulated by two individually adjustable regulating or control devices 34, but can also be done by a common device with an optional switchover option.
  • the heating ring area 19 of each heating zone 17, 18 is covered by an end cover 38 which rests on the edge 23 and is fastened to a central pin 36 in the central zone 20.
  • Each heating zone has its own connection line.
  • the heating zones 17, 18 can be heated simultaneously or independently of one another without causing undue warping or damage to the hotplate body.
  • the massive construction of the intermediate area 24 contributes to this. Nevertheless, the efficiency of heating only one zone is surprisingly good.

Claims (5)

1. Plaque de cuisson électrique comportant un corps en fonte (12), dont le dispositif de chauffage est constitué par des résistances électriques chauffantes (22) insérées dans des rainures (21) ménagées dans la face inférieure du corps (12) de la plaque de cuisson et disposées dans deux zones de chauffage (17, 18), caractérisée en ce que le corps (12) de la plaque de cuisson, constitué par une pièce métallique moulée d'un seul tenant et la surface de cuisson (15) formée par ce corps possèdent une forme allongée, que les deux zones de chauffage (17, 18) sont disposées côte-à- côte sur le corps de la plaque de cuisson et peuvent être chauffées séparément et qu'entre ces zones se trouve disposée une zone intermédiaire (24) continue et non chauffée du corps (12) de la plaque de cuisson, qui fait partie de ce corps en fonte (12).
2. Plaque de cuisson électrique selon la revendication 1, caractérisée en ce que les deux zones de chauffage (17, 18) sont agencées de manière à être symétriques l'une de l'autre, tout en étant par ailleurs identiques, les zones de chauffage (17, 18), circulaires ou en forme d'anneaux circulaires, étant avantageusement entourées par des bords périphériques verticaux (23).
3. Plaque de cuisson électrique selon la revendication 1 ou 2, caractérisée en ce que la zone intermédiaire (24) située entre les zones de chauffage (17,18) est réalisée en fonte, avec une épaisseur comprise entre 7 et 15 mm et de préférence de l'ordre de 10 mm, et que notamment la distance entre les bords (23) des zones de chauffage (17, 18) est comprise entre 1 et 3 cm.
4. Plaque de cuisson électrique selon l'une des revendications précédentes, caractérisée en ce que le corps (12) de la plaque de cuisson est limité, dans une vue en plan, par deux demi- cercles et par deux droites reliant ces derniers.
5. Plaque de cuisson électrique selon l'une des revendications précédentes, caractérisée en ce que chaque zone de chauffage (17, 18) possède son propre système de commande ou de régulation (34) ainsi que, éventuellement, son propre limiteur de température (33).
