Definitions

  • the invention relates to a cooking hob, in particular for an oven, especially for a domestic oven, comprising a panel shaped carrier element with an upper side and a bottom side, wherein at least one electrical heating element is arranged on the upper side of the carrier element, wherein the heating element is connected to at least one wire and wherein the wire is fed to an electrical connector plug for the supply with electrical energy.
  • FIG 1 where a pre-known domestic oven is depicted.
  • the domestic oven 2 has a hob 1 on its top.
  • the hob 2 has a carrier element 3 with an upper side 4 and a bottom side.
  • On the upper side 4 of the carrier element 3 a plurality of heating elements 6, 7, 8, 9 are located and fixed to the carrier element 3.
  • the hob 1 further comprises a cover made of glass ceramics.
  • FIG 2 the hob 1 is depicted without the cover of glass ceramics.
  • the electrical heating elements 6, 7, 8, 9 are placed on the upper side 4 of the carrier element 3 .
  • Each heating element 6, 7, 8, 9 has an electrical connection which fixes a wire 10, 11, 12, 13 to the heating element 6, 7, 8, 9 for supply of the heating elements 6, 7, 8, 9 with electrical energy.
  • the wires 10, 11, 12, 13 are fed along the upper side 4 of the carrier element 3 and can be guided through an opening in the carrier element 3. Then, the wires are fed to an electrical connector plug 14.
  • the assembly of the hob is quite complicated and thus expensive when using the pre-known design.
  • One aspect is that an automatisation of the assembly process is only possible with a high effort because it is complicated and thus expensive. Also, wiring of all heating elements can cause errors; this demands correction. Finally, the wire material is quite expensive and an economical use is not ensured.
  • the solution of this object according to the invention is characterized in that the at least one wire for the supply of the heating element with electrical energy is arranged at least partially at the bottom side of the carrier element, wherein an electrical connector between the wire and the heating element penetrates at least one opening in the carrier element.
  • the wire is arranged totally at the bottom side of the carrier element.
  • a plurality of heating elements can be arranged on the upper side of the carrier element, wherein each heating element is connected with an electrical connector which penetrates the carrier element.
  • a preferred embodiment of the invention comes up with the electrical connector consisting of at least two parts which are joined, wherein one part is arranged on the upper side and one part is arranged on the bottom side of the carrier element.
  • Both parts can e. g. be connected by a snap-on connection. Also other kinds of connection are possible.
  • the connector can also be made as a one-piece part having two different sections, one for remaining beside the heating element and one for penetrating the opening in the carrier element.
  • the electrical connector is preferably directly connected with the heating element.
  • heating element is arranged on the carrier element to provide different cooking stations on the hob.
  • heating elements are arranged on the upper side of the carrier element.
  • At least two of the heating elements can have different sizes for the different cooking applications.
  • the heating elements are resistance heating elements according to one embodiment of the invention.
  • other kinds of heating elements can be employed, e. g. induction heating elements.
  • the at least one opening in the carrier element is produced by punching.
  • a thin sheet metal panel is used for the carrier element.
  • the wires and a plurality of heating elements can be bundled at the bottom side of the carrier element to a cable loom. This cable loom is then guided to the electrical connector plug.
  • the hob can be a stand-alone or autarkic hob or part of an oven, in particular a domestic oven, and/or built-in or free-standing.
  • the hob can have a design using a ceramic or glass ceramic hob or stove top.
  • FIG 3 shows a cooking hob 1, in particular of an oven (depicted in FIG 1 ), according to one possible embodiment of the invention.
  • the hob 1 consists of a carrier element 3 which has a panel shape; more specifically the carrier element 3 has a rectangular shape and consists of a thin sheet metal.
  • On the upper side 4 of the carrier element 3 four heating elements 6, 7, 8 and 9 are located and fixed (fixing means not shown) wherein the heating elements are resistance heaters in the depicted embodiment. Also other heating elements can be employed, e. g. induction heating elements.
  • each heating element 6, 7, 8, 9 is in contact with an electrical connector 15, which is described in more detail later.
  • the wiring of the heating elements 6, 7, 8, 9 becomes apparent from FIG 4 where the bottom side 5 of the carrier element 3 is visible.
  • the heating elements 6, 7, 8, 9 are shown in dashed lines as they are not visible.
  • the electrical connector 15 penetrates an opening 16 which is machined into the carrier element 3.
  • the opening is produced by punching.
  • the electrical connector 15 consist of two parts 17 and 18.
  • the upper part 17 is located - in the mounted state of the hob - beside the heating element 6, 7, 8, 9 and directly connected to it, while the lower part 18 protrudes through the opening 16.
  • the wires 10, 11, 12, 13 are connected to the part 18 on the bottom side 5.
  • electrical connector 15 can also be designed in any other way.
  • the wires 10, 11, 12, 13 are collected in a central region of the carrier element 3 and run as a cable loom to an electrical connector plug 14 as in the prior art.
