Definitions

  • Electric hot plate according to the preamble of claim 1 have become known from DE-GM 81 03 701. They have an oval shape in plan view and a common heating system with inserted electrical heating resistors on their underside. They are used to heat elongated cooking or roasting dishes.
  • Circular hot plates are also known, which consist of separate or connected, heated rings.
  • the CH-PS 187 383 shows the connection of these rings by a sheet metal strip with a stretch bead.
  • 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 hotplate body has a parting line in the intermediate area between the two heating zones and the two hotplate body parts are connected to one another by a connecting means which allows a certain mobility, the efficiency is further improved. Nevertheless, the two cooking surfaces are exactly aligned with each other, so that a cooking vessel standing on both heating zones has good thermal contact.
  • the connecting means can maintain this orientation, that is, as far as possible not allow vertical displacement in the area of the connecting joint and also prevent the two cooking surfaces from tilting towards one another.
  • the intermediate area between the two heating zones is particularly preferably made of relatively thick cast material, so that there is no fear of warping of the cast body in this area.
  • an electric hotplate 11 which has a hotplate body 12 which is made of cast material, namely cast iron.
  • the hotplate body is made of 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 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, which is adjoined in the upper outer part by a projecting flange 35.
  • 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).
  • a ring or upper case edge 30 made of stainless steel with its inner portion 31 is pressed around the entire hotplate body and has the cross section of a has inverted V or U and is supported with its top 32 on the bottom of the flange 35.
  • An outer section directed obliquely outwards and downwards usually reaches over a raised edge of a mounting plate and is supported on the latter. 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 resting on the edge 23, which is attached 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.
  • a connecting means 28 is used, which, as can be seen from the detail in FIG. 5, consists of a sheet metal strip, for example made of stainless steel, into which a downward expansion bead 29 is stamped.
  • the parting line 25 In order not to allow the parting line 25 to become so large, it could be considerably narrower in the upper region when the bead is directed downward, or the bead could be directed upward and largely complete the parting line.
  • the connecting means 28 is connected to the upper rim 30 which surrounds the hotplate.
  • the upper rim 30 runs around the hotplate body and accordingly has an elongated, oval shape.
  • the connecting means 28 is attached to this upper fall edge, for example by spot welding or roll welding, and runs at the height of the upper region 32 of the upper fall edge, thus forming a web between the two essentially straight sections of the upper fall edge. This holds them together and presses them onto the hotplate body.
  • the connecting means could also, particularly in its design as a straight web 28a according to FIG. 6, be punched directly out of the material of the upper fall edge without an expansion bead and thus form a coherent unit therewith.
  • This version is selected if it is ensured that differences in longitudinal expansion can be accommodated at the ends of the hotplate or in the groove 26.
  • An embodiment without a groove 26 with an inverted V-shaped connecting means pressed onto the separating joint sides 37 can also be used.
  • the connecting means 28, 28a can absorb longitudinal deformations, but ensures that the flat cooking surface parts remain aligned with one another and that there are no vertical displacements that could lead to a step between the cooking surfaces and, in the case of a large-area cooking appliance, for example an elongated roasting pan, a gap between them would create him and one of the cooking surfaces. They also hinder an interlocking of the two cooking surfaces with one another, and possibly also angular movements of the cooking surfaces against one another, in particular in the embodiment according to FIG. 6.
  • the gap width of the parting line 25 should either be so large that it is possible to keep it clean from above, or the distance should be close to zero in order to prevent dirt from accumulating there. Since the temperatures are not very high in this area, a seal could be interposed there.
