Description

  • The present invention relates to a junction box for the power supply of a cooking hob according to claim 1. Further, the present invention relates to a cooking hob with at least one junction box for the power supply according to the preamble of claim 9.
  • Within a cooking hob the junction box for the power supply, in particular the electric terminals should be protected against the heat generated by the heating devices. In the prior art the junction box comprises a double-walled casing as a protection against the heat. Thus, the junction box is very broad and the distance to the heating device is relative small, so that at least the outer part of the double-walled casing becomes very hot.
  • Further, conventional junction boxes are insertable into a recess in a panel of the cooking hob from the exterior. Thus, the assembler has to turn-over the whole cooking hob during the production process in order to fasten the junction box at the cooking hob.
  • It is an object of the present invention to provide a junction box for the power supply of a cooking hob and a corresponding cooking hob, wherein the junction box has an improved protection against the heat and the mounting of the junction box at the cooking hob is simplified.
  • The object of the present invention is achieved by the junction box according to claim 1.
  • According to the present invention a junction box for the power supply of a cooking hob is provided, wherein:
    • the junction box is mounted or mountable in a recess of a bottom panel or a side panel of the cooking hob,
    • the junction box comprises an interior part associated with the interior space of the cooking hob and an exterior part associated with the exterior of the cooking hob,
    • the junction box comprises at least one latch element for fastening said junction box in the recess,
    • the junction box is insertable into the recess by a motion of said junction box from the interior space, and
    • the junction box comprises a plurality of electric terminals arranged in a central portion of said junction box.
  • The main idea of the present invention is the assembly of the junction box into the recess from the interior space of cooking hob and the arrangement of the terminals in the central portion of said junction box. The first point simplifies the production process of the cooking hob, since the casing of the cooking hob need not to be turned-over by the assembler. The second point improves the protection of the terminals against heat, since the temperature in the central portion is the lowest within the junction box.
  • According to the preferred embodiment of the present invention the casing of the junction box is single-walled. The single-walled junction box allows a smaller wide of the junction box and a bigger distance between the junction box and the neighbouring heating devices within the cooking hob. The air between the junction box and the heating devices delays a heating of the terminals and contributes to the cooling of the junction box.
  • In particular, the dimensions of the junction box are adapted to the structure of the cooking hob, so that the distances between the casing of the junction box and the neighbouring heating devices are maximised.
  • For example, the electric contact elements are arranged in a series within the junction box. This allows a relative big distance from the heating devices and contributes also to a reduced heating of the terminals.
  • Preferably, the cross-section of the exterior part of the junction box is marginally smaller than the cross-section of the recess in the bottom panel or side panel. Also this feature simplifies the assembly of the junction box in the cooking hob.
  • In order to allow a stable fixation of the junction box in, the recess, the junction box comprises supporting elements for supporting said junction box at the edge and/or at the border of the recess. In particular, the junction box comprises appendices arranged at least partially on an opposite side of the latch element, wherein at least one edge of the recess is engageable into said appendices.
  • Further, the junction box comprises detection means for sensing the temperature of the electric terminals, in particular of the electric terminals in the interior part of said junction box. The power supply for the heating devices of the cooking hob can be reduced or switched off, if the temperature of the electric terminals is too high. This is an additional feature for preventing a destruction of the junction box.
  • The object of the present invention is also achieved by the cooking hob with a junction box for the power supply according to claim 9.
  • According to the present invention the cooking hob comprises at least one junction box as described above.
  • The production process of the cooking hob is simplified, since the casing of the cooking hob need not to be turned-over by the assembler. The protection of the terminals against heat is improved, since the temperature in the central portion is the lowest within the junction box.
  • According to the preferred embodiment of the present invention the position and the dimensions of the junction box are adapted to the structure of the cooking hob, so that the distances between the casing of the junction box and the neighbouring heating devices are maximised. The air between the junction box and the heating devices delays a heating of the terminals and contributes to the cooling of the junction box.
  • Further, the cooking hob comprises a glass-ceramic panel forming the top side of said cooking hob. Preferably, a barrier is arranged between the junction box and the glass-ceramic panel in order to hold the heat off from a top side of the interior part of said junction box.
  • The novel and inventive features believed to be the characteristic of the present invention are set forth in the appended claims.
  • The invention will be described in further detail with reference to the drawings, in which
