  • the radiant heaters 8, 9, 10, 11 may be identical and have identical constructions and performances. However, it can also be provided that the radiant heaters 9, 10, 11 have different diameters and powers. Likewise, the invention remains applicable.
  • a temperature limiting unit is attached to the radiant heater 8 as a protector 14.
  • the protector 14 has a sensor tube 24, which is arranged in the plan view above the heating conductors 12, 13. In this way, the sensor tube 24 of the protector 14 is acted upon by the same heat radiation as the radiant heater 8 associated heating zone 4 of the glass ceramic plate 3.
  • the sensor tube 24 is attached to a retaining plate 23 externally mounted switch housing 26. In the switch housing 26, a first switching contact 25 is arranged, which can be actuated by means of the sensor tube 24.
  • a switching threshold of the first switching contact 25 is set such that the glass ceramic plate 3 is protected against overheating, which is why the switching contact 25 is set such that it switches off automatically at a first maximum temperature of 550 ° C here. If the temperature then drops to 500 ° C., the first switching contact 25 is automatically switched on again by means of the sensor tube 25. As a result, an overheating protection for the glass ceramic plate 3 is ensured.
  • the first switching contact 25 is used to turn off both the first and the second heating conductors 12, 13 together, in front of the glass ceramic plate 3 To protect overheating.
  • the radiator 8 is thus connected in total here.
  • a terminal lug 31 is provided, to each of which one end of the heating conductors 12, 13 is connected.
  • Fig. 4 shows a typical concrete application in the normal operation of the heating of a filled with food 18 pot 17, which is placed on the heating zone 4 of the hob 2. From the schematic sectional view according to Fig. 4 It can be seen that the pot has a crown 19, which leads in the center of the bottom of the pot 17 to an air gap to the glass ceramic plate 3. The pot 17 is therefore only in an outer edge region in contact with the glass ceramic plate 3, so that in this area heat due to radiation and heat conduction in the pot bottom of the pot 17 can be performed. In the inner area, however, heat transfer is possible only due to radiation. As a result, the heat transfer from the heating zone 4 is reduced to the bottom of the pot 17 in the center, so that in the prior art in this area comes to overheating. As a result, the protector 14 turns off both the first and second heating conductors 12, 13 regularly so that the glass-ceramic plate 3 is not overheated. The protector 14 thus causes a clocking of the radiator 8 by means of a first switching contact 25th
  • the invention now makes use of the knowledge that the total transferable thermal power can be increased if the protector 14 less often, preferably not, must intervene in the intended heating operation. This can be achieved by reducing the mean thermal surface power density of the second heat conductor 13 so that the conventional overheating in the central region of the heating zone 4 can be avoided.
  • the invention achieves this by a small change to the radiant heater 8 and its protector 14.
  • the protector 14 usually has a second switching contact 16, which is commonly used in the prior art to operate a heating indicator. In cooktops of the generic type, however, it is often no longer necessary to use this second switching contact of the protector 14.
  • the hot indication is usually via the control device 20, which has its own measuring and / or control devices for this purpose.
  • the second switching contact 16 is connected via a connection contact 32 to the control device 20 (not shown), which evaluates this. According to the evaluation, only the second heating conductor 13 is operated and its temperature threshold is set such that it lies below the temperature threshold at which the first switching contact 25 is actuated. It is thereby achieved that the mean thermal surface power density in the central region is reduced on average due to the early engagement of the switching contact 16, so that the first switching contact 25 need not or only very rarely be actuated by the sensor tube 24.
  • the second switching contact 16 is actuated by the same sensor tube 24, so that no additional components are required.
  • FIG. 5 schematically shows a diagram in which the time t is shown on the abscissa and the temperature T in the region of the heating zone 4 on the ordinate.
  • a first graph 27 shows a temperature profile which is achieved with the method according to the invention, as explained above.
  • Another graph 28 illustrates in parallel a temperature profile according to the prior art.
  • the invention sets up a temperature profile in the region of the heating zone 4 according to the graph 27. It can be seen that, after the time t 1 has been exceeded, a clocking due to the second switching contact 16 takes place with a significantly smaller amplitude and period. As a result, overall the average temperature according to the graph 30 can be significantly above the mean temperature according to the graph 29, which is why the maximum transferable thermal power is increased accordingly. As a result, a cooking time can be significantly reduced, so that overall a boost function can be provided.
  • the invention therefore requires particularly little or no additional elements in a particularly advantageous manner. It can be realized with the existing resources, so that not only a simple retrofitting, but also a simple addition to an existing production line can be achieved. In particular, it is not necessary to detect when the protector intervenes switching, or to detect the course of an electric current or an electric power of the radiator 8.
  • the mean thermal surface power density does not exceed 7 W / cm 2 , in particular 6 W / cm 2 , particularly preferably 6 to 7 W / cm 2 . If the thermal surface power density is limited to the predetermined value, an intervention of the protector 14 can be substantially avoided.
  • the transmitted power due to the different thermal surface power density in the cookware leads to substantially no impairment of a temperature distribution in the bottom of the cookware. This is due, inter alia, to the fact that high thermal outputs are essentially required to heat up liquid cooking product 18, which by itself already ensures temperature compensation due to its properties. Moreover, in frying operations, the high thermal performance is usually only required for heating the cookware for frying, requiring significantly less power during the actual frying process. As a result, however, the boundary conditions that lead to the intervention of the protector 14, as a rule, no longer exist, so that in this case, a largely uniform thermal surface power density can be provided as in the prior art, that is, a very homogeneous temperature distribution can be reached in the bottom of the pot.

  • a cycle time or a cycle time of the second heat conductor 13 is designed as short as possible in a boost operation. This allows a higher temperature level can be achieved (see Fig. 5 ), which can further reduce the cooking time.
