Definitions

  • the invention relates to a hob with a hob plate and a plurality of heating units arranged below and a method for illuminating such a hob.
  • the invention is based on the object to provide an aforementioned cooktop and methods with which problems of the prior art can be avoided and in particular for hobs with several individually compiled activatable heating units that form freely determinable cooking, their operation undoubtedly display.
  • the heating units adjoin one another relatively directly and without large gaps and can be activated individually or can be supplied individually with power. They are operated together in certain patterns or in certain areas in such a way that they form a heating surface which can be determined in terms of position and size. This then corresponds to a hitherto known cooking area of a hob on which exactly a cooking vessel is set for heating.
  • the hob has a lighting associated with the heating units.
  • a plurality of illuminations are arranged or provided which essentially directly adjoin one another or extend along the outer contours of the heating units.
  • the outer contour of a heating unit can be marked or also displayed through a hob plate, in particular a glass ceramic plate. These lights are arbitrary controllable.
  • heating units can be controlled by a controller according to the method according to the invention in such a way that only heating units subjected to power are illuminated or displayed by the lighting.
  • a hob can recognize, over which heating units a cooking vessel is. Even before an application of power, these heating units can then be marked in a corresponding manner by illumination, so that before activating the power, an operator knows which heating units or which surface resulting therefrom is affected as heating surface and is heated.
  • heating units are energized.
  • a division is advantageously made where a heating unit abuts or borders on one or two adjacent heating units. Likewise, a subdivision can take place at corners of heating units which have the shape of polygons. In particular, illuminations are subdivided at each corner, or there are two separately activatable illumination segments abutting one another.
  • illumination may have individual spots of light that are arranged along a line and thus also visually create the appearance of a luminous or illuminated line. This line runs along the outer contour or along one side of a heating unit.
  • either individual, point-like lighting elements can be used, for example, temperature-resistant incandescent lamps or cheap spot-type LEDs.
  • LEDs can be used in conjunction with optical fibers and Lichtverteil devices or elongated or beam-like bulbs or LED.
  • the heating units have a polygonal or even polygonal shape, which is in particular such that a plurality of these heating units composed a surface substantially completely cover.
  • a lighting segment Along each edge or side in such a heating unit is a lighting segment.
  • Each lighting segment is independently controllable from the others.
  • the illumination of the outer contours of individual heating units or an entire heating surface formed gives further possibilities for different operating modes or for displaying specific information for an operator, which can advantageously be detected intuitively. For example, it is possible that the illuminations are varied in terms of their brightness. Thus, for example, after placing a cooking vessel in a lower lighting level, the resulting entire heating surface can be displayed. If this heating surface is actually powered by the individual heating units, the brightness may be increased to a higher brightness level to indicate actual operation. Furthermore, it is possible to vary the brightness according to a set power or cooking level.
  • a flashing signal ing the selection of heating units and a continuous lighting the actual operation of these heating units.
  • a circulating light signal is possible, that is such that in each case one lighting segment after the other is briefly activated and revolves in alternation or circulation on an activated heating surface.
  • a hob 11 which has a hob plate 12 which is translucent and advantageously consists of glass ceramic or toughened glass.
  • a hob plate 12 which is translucent and advantageously consists of glass ceramic or toughened glass.
  • heating units 14 are arranged below the hob plate 12. These are formed hexagonal, in particular substantially uniformly, ie with equal long edges 15, and arranged so that they connect directly to each other similar to a honeycomb-shaped surface. Substantially they cover the surface of the hob 11 and the hob plate 12th
  • the one heating unit 14a has a support 16a, for example of insulating material such as ceramic. Attached thereto is an induction coil 17a, which, as it were, represents the heating of this heating unit 14a.
  • a further heating unit 14b is shown, which likewise has a carrier 16b and lighting segments 19.
  • this heating unit 14b has a heating conductor band 17b and is designed as a radiant heater, as is known to the person skilled in the art.
  • Regarding the formation of such individual heating units is on the DE 103 14 690 A1 and on the EP 12 06 164 A2 The contents of this description are hereby incorporated by express reference.
  • lighting segments 19 are arranged. These are each almost as long as one side of a heating unit 14. It can be seen in the combination of several directly juxtaposed heating units 14, that in each case along the boundary lines or between two heating units 14, a lighting segment 19 extends. On the downwardly facing side, which adjoins an edge of the hob 11, although no subsequent heating units are provided on the lower heating units 14. Nevertheless, the illumination segments 19 are also arranged along the sides or edges 15 here.
  • FIG 3 is the hob 11 off Fig.1 represented with two attached cooking vessels 21a and 21b, which are shown in the plan view only as a circle. They each cover a few heating units 14 of the hob 11 so far that they are determined by means of a cooking vessel, not shown, which is advantageously integrated in each heating unit 14, as selected for heating operation.
  • the lighting segments 19 of the selected heating units 14 are activated by a control of the hob 11, not shown. They form a luminous border of the selected heating units 14 or by it certain or formed heating surfaces 23a and 23b, which are illustrated by a slight hatching. On the basis of this luminous border through the illuminations 19, an operator can recognize which heating units 14 are intended for operation and may already be operated or be supplied with power.
  • illumination segments 19 are not activated within the heating surfaces 23a, b or at adjoining and activated heating units 14. This has already been described above and serves to actually mark the entire heating surface produced and not the individual heating units 14 that form it. Thus, an operator does not even see how the heating surfaces 23a, b ultimately consist of individual heating units 14, but only perceive them as a whole in correspondence with another hob of a cooking hob.
  • control the individual heating units 14 is on the above with respect to the formation of such individual heating units is on the DE 103 14 690 A1 and on the EP 12 06 164 A2 directed.
  • the control of the individual lighting segments 19 can be effected in a particularly simple variant in that they are always operated together with the surrounding heating unit 14, that is, for example, are coupled to the same power supply. However, then it is not possible to illuminate only the outer contours of a generated heating surface 23.
  • each lighting segment 19 may be provided to provide a separate supply line for each lighting segment 19.
  • they can be provided with their own control and a control system in the manner of a bus system, which is controlled by a hob control.
