Definitions

  • the present invention relates to an electric heating plate for heating or keeping warm food and drinks, in particular for melting, grilling, roasting or cooking.
  • the invention particularly relates to an electrically heatable Tischfondue réelle equipped with such a hot plate.
  • Electric hotplates or hot plates for household use have long been known. They are distinguished from other sources of heat, in particular with respect to open flames, which arise when burning gaseous or liquid fuels, by an increased level of security. In addition, the handling is much easier and more convenient because no additional fuel is required.
  • a disadvantage of electric hotplates is that by avoiding an open flame also typically associated with fire and flames pleasant soothing and relaxing atmosphere is lost, especially in ceremoni meals, such as in the various types of fondue or raclette food, often is desired.
  • the present invention is therefore based on the technical problem of providing an electrically operated hot plate, which provides the charm and the atmosphere with unchanged high safety level and ease of use, which is connected to heaters that work with open flames.
  • the subject of the invention is accordingly an electric heating plate with at least one electric heating element and a supporting surface, which is characterized in that at least one electric flickering light source is arranged under the supporting surface.
  • the located under the support surface Flickering light generates an optical impression during operation of the heating plate, which comes quite close to an open flame, so that it is possible to produce a correspondingly advantageous and pleasant atmosphere even with a purely electrically operated device.
  • a flickering light source for example, one or more light-emitting diodes can be used, wherein because of the more advantageous spectral distribution of the resulting light incandescent or gas discharge lamps, which generally give a perceived as warmer light, are preferred.
  • the light source is driven by a flicker circuit known per se, which varies the supplied current irregularly.
  • the circuit can also be designed so that the user, for example via a selector switch, can specify whether the flickering light source is to be operated in flickering mode or in continuous mode. This allows the user to additionally influence and optimize the desired lighting mood.
  • the heating element and the flickering light source are actuated via a common switch, so that the flickering light source also serves as an operating indicator of the heating plate.
  • the switch which may be formed, for example, as a rotary switch, may also allow regulation of the heating power of the heating element.
  • the intensity of the flickering light source either remain constant when the heating power is changed, so it can be switched so that its intensity also changes with the change in heating power, so that information on the heating power can be obtained via the brightness of the flickering light.
  • the circuit can also be done so that with increasing heating power flicker lights are switched on.
  • the heating plate comprises a base, in which the flickering light source is arranged.
  • the base is designed so that the light generated by the flickering light source can escape to the outside.
  • the base may have any desired openings.
  • the socket as be formed open stator structure.
  • the support surface rests on, for example, three or four struts, so that the light can penetrate almost unhindered in all directions to the outside.
  • the base may also have transparent and translucent windows.
  • the invention also relates to an electric table fondue device comprising an electric heating plate according to the invention as defined above and a pot arranged on the support surface of the heating plate.
  • the pot may be firmly connected to the support surface, but preferably it is removably disposed on the footprint. In the latter case, the footprint preferably has a raised edge to prevent slipping of the pot.
  • Figure 1 of the drawing shows an electric Tischfondue réelle as a typical application example of the heating plate with flickering light.
  • the electrical Tischfondue réelle is designated overall by the reference numeral 10.
  • the Tischfondue réelle consists of a heating plate 11, which comprises a support surface 12 and a base 13.
  • a heating element 14 is arranged, which can be connected via a cable 15 to a power supply, not shown here.
  • a rotary switch 16 the heating element 14 is turned on and its heating power can be controlled.
  • a cast-iron removable fondue pot 17 is arranged, in which cheese can be melted.
  • the support surface 13 has a raised edge 18, which prevents slippage of the fondue pot when handling the typical for Fondueessen, but not shown here, stocked with bread cubes skewers.
  • an electric flickering light 20 is disposed in the base 13 of the Tischfonduegeres 10 below the support surface 12, which is also supplied via the line 15 with power and controlled by the switch 16. Since when switching on the Tischfonduesammlungs 10 via the switch 16 at the same time the heating element 14 and the flicker light 20 are activated, the flicker light 20 also serves as a visual indicator of operation of the device.
  • the flickering light 20 comprises an incandescent or gas discharge lamp 21 which is supplied with electrical current via a flicker circuit 22, shown in broken lines, whose intensity is changed irregularly by the flicker circuit, so that the lamp 21 emits light with a correspondingly varying intensity ,
  • the support surface 12 rests in the illustrated example on three struts 23, 24, 25, wherein the gap between the struts is open, so that the flickering light generated by the lamp 21 can be released almost unhindered in all directions.
  • a strut 25 of the three struts may be slightly larger and receive the control electronics for the heating plate and the flicker circuit 22.
