Definitions

  • the invention relates to a device with an operating and display unit and a hob with at least one heating zone, in particular for an electric built-in hob, the operating and display unit being provided with an operating and display element for setting an electronic control unit, which control signals for controlling Power switching elements of a heating element assigned to the heating zone are generated, this operating and display unit also being arranged in a section of the glass-ceramic, flat hob plate.
  • cooking stoves and built-in cooktops are equipped with appropriate controls for the user.
  • These operating elements can be combined with suitable display elements to form an operating and display unit.
  • the display elements are used, for example, to display the switch-on states the heating zones, the temperature or other information.
  • Rotary switches are known as controls of simple design; however, touch-sensitive sensor elements can also take their place. Display elements designed as light-emitting diodes are also known.
  • the starting point of the invention is a known hob plate, in which the operating and display elements are integrated in the hob plate.
  • the operating and display elements for several heating zones are combined in one operating and display unit.
  • Such a design is used above all for hob plates made of heat-resistant glass plates, for example of the glass ceramic material known under the trademark CERAN.
  • CERAN glass ceramic material
  • the height of kitchen worktops which are intended to accommodate built-in cooktops, is limited to a relatively low value of, for example, 40 mm by standardization, and this depth should not be exceeded for installation reasons, even when inserting a cooktop.
  • the glass-ceramic plate forming the hob is not intended to protrude significantly above the surface of the kitchen worktop, it appears difficult to heat-sensitive electronic components in the small installation space available as well as to accommodate operating and display elements.
  • Another problem is the dissipation of the energy loss of the power switching electronics, which is also released as thermal energy and can damage the electronic components, in particular the sensitive sensor elements and the power controller, by excessive heat. It has therefore not been possible to accommodate these parts with relatively flat cooktops with a small installation depth according to the dimensions specified above.
  • a hob is known from DE 38 02 406 A1, which forms the preamble, in which a functional part is inserted in a corner region of the hob plate.
  • This functional part forms an operating and / or display unit. Since there is no height offset of the functional part compared to the hob, there is no increase in the free installation height for the installation of operating and display elements. In addition, the remaining joint between the functional part used and the hob plate is not closed, so that remnants of overflowed food can get stuck.
  • the state of the art also includes a switch point indicator according to CH-A-402 210.
  • This is a control panel in a trough-shaped housing part, which does not have a flat cooktop plate on its upper side, but individual hot plates inserted into a stove top plate.
  • the display device is combined with the operating handles, which is used as an insert component next to the hot plates in the stove top.
  • the insert component does not form part of a hob plate or the stove top plate, but remains a separate component.
  • the invention is based on the task of designing a hob, in particular for a built-in hob, in such a way that, while maintaining the advantageous combination of operating and display elements, better cooling conditions are achieved even with a relatively small installation depth of the hob, and the disadvantages of the known forms of training are avoided .
  • the cooktop has a raised plate part, which at least partially overlaps the cutout, above the cutout, and in that the operating and display elements are arranged on this raised plate part.
  • the built-in hob can accommodate all of the electronics, including the power section, despite its low installation depth.
  • Sensor buttons are preferably used as operating elements, so that a cleaning-friendly surface of the operating and display unit is achieved in connection with flat display elements.
  • An advantageous embodiment can provide that an additional cooling rail for connection to at least one in the region of the cutout a power switching element is provided. With such a design, the electronic control unit can also be arranged below the attached plate part, with a sufficient cooling effect being achieved.
  • the thermal load on the electronic built-in parts can optionally be further reduced by using the edge surround as a heat sink in the case of an existing metallic edge surround of the hob plate and preferably connecting it to at least one power switching element. It also appears expedient to connect an additional cooling rail present in the region of the cutout to the metallic edge border.
  • the attached plate part can be constructed in various ways, preferably triangular, sector-shaped or rectangular or composed of such contours. In order to achieve a greater free installation height below the raised plate part, it can also be expedient to place the plate part on the hob plate with the interposition of a spacer part which preferably also overlaps the hob plate at least in sections.
  • the plate part can consist of a blank made of glass-ceramic material.
  • the attached plate part can also be expediently connected to the hob plate by a heat-resistant adhesive connection.
  • FIG. 1 shows a built-in hob 2 built into a recess in a kitchen worktop 1, which is provided with an operating and display unit 5 in a front corner region 3 of a glass ceramic hob 4.
  • the hob plate 4 which is flat on its upper side 6, has four heating zones 7, each with an electrical resistance heating element (not shown) below the ceramic hob plate 4.
  • the essentially rectangular hob plate 4 is provided with a triangular cutout 8.
  • a plate part 9 is glued overlapping as a glass-ceramic plate cut corresponding to the shape of the cutout 8 on the upper side of the cooktop plate 4 with a constant width B (see FIG. 2).
  • the plate part 9 is opposite the hob plate 4 aligned so that its side surface 10 is flush with the side surface 12 of the hob 4 and its side surface 11 with its side surface 13.
  • an operating element in the form of a sensor element 20 and a light-emitting diode as a display element 21 for displaying the heating level set by the sensor element 20 are arranged in the plate part 9 for each heating zone 7.
  • feed lines (not shown) transmit electrical signals from the sensor elements 20 to an electronic control unit 22 located below the plate part 9.
  • this generates control signals for controlling power switching elements 24, which in turn supply the supply voltage for the resistance heating elements of the heating zones 7 .
  • the power switching elements 24 are triacs.
  • the power switching elements 24 are placed on a cooling rail 30.
  • a further improvement in the cooling effect is achieved in that the cooling rail 30 is connected to a metallic edge border 31 of the hob plate 4 and the plate part 9 in the form of aluminum profile rails as a heat sink.
  • the edge border is connected directly to the brackets of the power switching elements.
