  • FIG. 7 of DE 43 33 334 A 1 shows a one-piece plate made of glass-ceramic with a peripheral outer peripheral region deviating upwards from the height of the inner main plane of the plate in which the cooking zones are arranged. In this case, radial diameter between the main plane and deviating from her edge region of 4 mm to 100 mm claimed.
  • Assembly units for a cooktop with glass ceramic surface go out from DE 43 04 370 A1.
  • An arrangement for attaching glass ceramic cooking surfaces in my edge area of a worktop, which tapers to a thin edge, is known from EP 0 846 921 A1.
  • the object of the invention is to provide an arrangement of a one-piece molding of glass ceramic, glass or ceramic, with a deviating from the main plane, peripheral outer edge region in a section of a worktop, which avoids the disadvantages and weaknesses of previous designs and embodiments and Moreover, can be realized easily and inexpensively, with low installation costs. Furthermore, it is an object of the invention to find an arrangement that offers a high level of user and cleaning comfort, controllability, ease of maintenance and safety.
  • This object is achieved according to claim 1 by the arrangement of a one-piece molding of glass ceramic, glass or ceramic, as cooking surface of a cooking appliance in a section of a countertop, with one of the height of the inner main plane of the integral molding, is arranged in the at least one cooking zone, upwardly deviating, peripheral edge region, wherein the one-piece molding is inserted flush in the cutout of the worktop, or according to claim 2 by an arrangement og one-piece molding, wherein the one-piece molding rests by means of its peripheral edge region on the edge of the cutout of the worktop.
  • peripheral edge region is 20 mm to 80 mm wide according to claim 1 or claim 2.
  • the common with the worktop, sealing joints of the integral molding are arranged so that they are neither temperature-loaded, nor accessible from overflowing cooking. This relatively wide, peripheral edge area, this can be particularly well and easily realized.
  • the molded part lies in or on the cutout of the worktop.
  • the advantages of the trough-like geometry of the molding are made accessible in the simplest way.
  • the surrounding raised edge area also serves as a frame and overflow protection, and acts as an obstacle against accidental pulling hot pots from the actual cooking surface. Since the peripheral frame portion of the one-piece molding functioning as a frame is made of the same material as the inner cooking portion, the entire one-piece molding can be decorated in the same manner with the same decorations and colors, thus producing a harmonious visual appearance. Since no separate frame of other material procured and this must not be glued in addition, work steps and material are saved.
  • the one-piece molded part rests on a mounting frame connected to the cutout of the worktop by means of its circumferential edge region and is infinitely adjustable in height, further advantageous arrangement possibilities of the molded part relative to the worktop can be realized. If desired, the arrangement can be made so that the surface of the peripheral edge region protrudes over the surface of the worktop by a certain amount or is lowered relative to this.
  • the one-piece molding may have a grinding, in particular a Flachfacetten- or C-cut on the outer edge. This is particularly advantageous when the surface of the peripheral edge region of the one-piece molding is arranged higher than the surface of the work surface. In this arrangement, the outer edge is completely or partially free. By grinding the outer edge, a significant increase in the breaking strength is achieved in the edge region, at the same time a transition region between the worktop and molding is created. The fact that the outer edge is ground, the danger is cut at the edge to be cut.
  • the inner main plane of the one-piece molded part, in which at least one cooking zone is arranged, is trough-shaped with respect to the circumferential edge region, in particular lowered by 2 mm to 4 mm.
  • the inner main plane of the one-piece molding and the peripheral edge region have mutually large transition radii, in particular transition radii of 10 mm to 50 mm.
  • transition region between the lowered inner region and the raised outer region is very soft, with large radii and the inner main plane, in particular lowered by 2 mm to 4 mm, is indeed a noticeable resistance when coating cookware, but no sharp edge. which can be damaged, present.
  • the inner, lowered main plane may have upward and / or downward deviating areas, the areas as far as they are executed are, individual cooking zones can be assigned.
  • the fact that the transition region also has large transition radii, in particular transition radii of 10 mm to 50 mm, the above-mentioned advantages.
  • the one-piece molding can be glued liquid-tight with the worktop and possibly also with the mounting frame, in particular by means of a silicone adhesive.
  • the splices are located outside the hot cooking area on the outer circumferential edge region and are therefore not particularly temperature burdened or endangered by overflowing food. The risk of permanent heavy contamination of the adhesive or sealing points is significantly minimized. Thus, bright, for example, the color of the worktop adapted adhesive can be used. In addition, these no longer have to be particularly temperature-stable.
  • the lowered inner cooking area can be filled with water for cleaning, which can be additionally heated by switching on the heating plates.
  • water for cleaning can be additionally heated by switching on the heating plates.
  • the circumferential edge region of the one-piece molding can be asymmetrical or symmetrical only on opposite sides.
  • the one-piece molding can be used as a cooking surface and / or roasting surface for electrically and / or gas and / or solid fuel and / or inductively heated cooking appliances.
  • At least one control and / or display zone is preferably assigned to the peripheral edge region of the one-piece molded part.
  • the operating and / or display zone can be arranged particularly preferably on the front edge area or on the lateral edge area of the one-piece molded part be.
  • An arrangement on the rear edge area - as preferred in some countries - can also be realized. This achieves a particularly high degree of operating convenience, controllability and safety.
  • the control and / or display zone is located on the raised peripheral edge area and is thus not exposed to the high temperature load of the actual cooking zone, accidental coating of hot cookware or overflow of food is prevented by the lowered inner main level.
