  • the receptacle is arranged at a distance x to the inside of the edge of the insulating support, the minimum value of which is selected so that the short-term temperature changes occurring when the heating coils or the halogen lamps are switched on and off have only a negligible influence on the temperature sensor.
  • the maximum value of the distance x is chosen such that the delay in the control characteristic caused by the thermal conductivity of the glass ceramic plate results in a small hysteresis. As a distance x widths of 3 mm to 6 mm have proven to be advantageous.

  • the temperature limiter namely the mounting space in the region of the outer peripheral wall of the heating element is limited, on the other hand, it is favorable if the various electrical connections of the temperature limiter and the temperature sensor are as close as safety-friendly together.
  • the element is formed at least in two parts.
  • a receiving part for the temperature sensor consists of a softer material to the receiving part application and safety specifically optimally geometric shape to can. It should also be noted that the thermal conductivity of the material used is sufficient.
  • the remainder of the element may consist of another, for example, harder material, wherein in particular a spring material is suitable in order to be able to press the element defined on the underside of the glass-ceramic plate.
  • the element is designed as a torsion spring, wherein the torsion region of the spring element is provided substantially outside the heating element and thus in a cooler area.

In the region of the heating element 5, the hob plate 3 is usually decorated accordingly on its upper side. In this heated area a cooking vessel 6 is shut off. The bottom of the cooking vessel 6 is in the cold state often only in the edge region of the heating element 5 in an annular surface on the hob plate 3, while in the central residual region of the pot bottom is spaced by an air gap from the plate (Fig. 1). In the heated state, this air gap is reduced or ideally to approximately zero by the known thermally induced movement of the pot bottom.
  • the heating element 5 has a cup-shaped sheet metal pot 7, in which a circular disk-shaped insulation plate 9 is located. Furthermore, an inner insulation ring 11 and an outer insulation ring 13 corresponding to a two-circuit heating arrangement are provided within the sheet metal pot 7 on the insulation plate 9. As a result, the interior of the heating element 5 is separated into an inner and an outer heating region, in each of which a Bandterrorismleiter 15 extends (Fig. 1, Fig. 2). In known manner, a Schuleiteran gleichteil 17 is fixed in the region of the outer peripheral wall of the sheet metal pot 7, which is on the one hand conductively connected to the Bandterrorismn 15 and on the other hand to not shown electrical supply lines of the hob 1 can be connected (Fig. 2).
  • the heating element 5 also has a known temperature limiter 19, whose rod extends transversely across the heated region of the heating element.
  • the terminal block of the Temperaturbeskyrs 19 has the well-known and usual, laterally issued Kunststoffflachsteckite for connection to the power supply line or to the Schuleiteranschlußteil 17 of the heating element 5.
  • an insulation block 21 is disposed in the region of the temperature limiter 19. This can serve to thermally shield the temperature limiter 19 in the region of sections of the band heating conductor 15 guided below the insulation block 21.
  • a receiving recess 23 is milled in the top thereof.
  • a heat-conducting element 25 is arranged with its element hood 27 (FIGS.
  • hood 27 is not seated directly on the bottom of the recess 23 so that the hood 27 can yield slightly to a blow on the hob plate 3. As a result, damage or breakage of the plate 3 can be avoided, especially if it is made of glass or glass ceramic material.
  • the element hood 27 In the receiving space formed by the element hood 27 is by means of a temperature-resistant and thermally conductive ceramic adhesive 28 as a temperature sensor 29, a PT-500 probe embedded with its sensor leads 30 and thereby secured and guided.
  • the material of the element cover 27 is X7 steel and the hood 27 is designed as a bent part.
  • the hood material must have sufficiently good heat conduction properties, must be well deformable, as explained below, but sufficiently mechanically stable over the entire temperature range of up to 350 - 400 ° C, and retain its properties even at these temperatures.
  • two side walls 31 are bent substantially at right angles down (Fig. 3). Also bent at right angles to the side walls 31 define bottom walls 33 a slot-shaped open bottom of the element cover 27.
  • the front side of the receiving space of the hood is closed by a right angle bent from the top wall end wall 35.
  • the hood-like design of the element 25 ensures that the safety-prescribed air and creepage distance to the live temperature sensor 29 is maintained in the event of breakage of the hob plate 3, without the base of the element 25 and the hood 27 and thus of the insulation block 21 too large to have to shape. More detailed explanations on the geometric design and arrangement of the temperature sensor 29, the element 25th and the isolation block 21 are made in conjunction with the description of the third embodiment outlined in FIG.
  • the hood 27 is fixedly connected to a substantially L-shaped hood carrier 37 made of steel, preferably welded. For this purpose, the element hood 27 is seated on a connecting section 39 of the hood carrier 37 (FIG.
  • the top wall of the element hood 27 is slightly elevated relative to the top of the hood support 37 and defines and limits a surface area A in which the element 25 rests on the underside of the hob plate 3 in a heat-conducting manner (FIGS. 1, 2, 5). Due to the overlapping connection of hood 27 and hood carrier 37, the stability of the connection is also increased. While the cage carrier 37 is made of 0.8 mm thick material in order to be suitable for the earthing plug-in connections described below, the element cover 27 is made of thinner material, which additionally simplifies their forming.
  • the hood carrier 37 merges in a spring section 41 into a mounting section 43 (FIGS. 2, 3).
  • the spring portion 41 is arranged substantially outside the heated region of the heating element 5 and the outer insulating ring 13.
  • the mounting portion 43 of the hood support 37 has a rectangularly downward bent mounting plate 45 with mounting holes 47.

  • the intermediate mounting part 48 is bolted on the one hand to the underside of the sheet metal pot 7 in the bottom thereof (not shown). This part 48 extends approximately L-shaped from the bottom of the heating element to its side wall 7.
  • the heat-conducting element 25 is then screwed to the intermediate mounting part 48 and thus defined in terms of height the position of the heat-conducting element 25 defined.
  • the heat-conducting element 25 can also be screwed to the outer wall of the sheet-metal pot 7 in the region of the assembly openings 47.
  • a connector can be attached (not shown), with the one hand, the electrical sensor leads 30 of the temperature sensor 29 connectable, for example, are attachable, and on the other hand electrical connection lines of a control unit 101 (Fig.
  • connection part is further to ensure that the electrical connections of the PT temperature sensor 29 to ground or the grounded hood carrier 37 are isolated.
  • the temperature sensor and the sensor lines 30 are covered over the entire length of the heat-conducting element 25 deck.
  • the mounting plate 45 has a flat pin 49 to which a grounding line 51 and their standardized AMP plug of the hob is directly pluggable. As a result, the heat-conducting element 25 is set to ground potential.
  • the ohmic resistance of the element 25 is at a value of 0.1 ohms or less in order to withstand a continuous current load of at least 25 amperes. Furthermore, the heat-conducting element 25 must not be made too stiff in order to be able to give in properly under mechanical loading or movement of the hob plate 3. Otherwise would be feared by a too stiff concern of the element 25 and the element cover 27 on the hob plate 3 hotplate chipping on the underside of the plate 3 or possibly also their breakage.
  • Fig. 4 is shown in sections in a cross-sectional view transversely to the longitudinal extent of the element and thus approximately perpendicular to the line II in Fig. 2 of the hob shown in which the temperature sensor 29 together with a heat conducting element 75 in the region of the insulation block 21 similar to the first embodiment is arranged.
  • the heat-conducting element 25 has no element hood, but rather an element shell 77. This element shell is also arranged in a suitable receiving recess 23 of the insulation block 21.
  • the insulation shell lies in its edge regions in an annular surface directly on the underside of the glass ceramic plate 3 and is thus in thermally conductive connection with it.
  • the temperature sensor 29 is arranged, wherein the shell is additionally filled by a thermal paste.
  • the heat conducting element 75 not shown in detail could otherwise be shaped like the heat conducting element 25 of the first embodiment. For safety reasons, however, the temperature sensor 29 is operated with a safety extra-low voltage or transmits its measuring signal without contact from the heating element.
  • the heat-conducting element 85 designed in the shape of a hood has an element hood 87 which corresponds to that of the first exemplary embodiment.
  • a mounting portion 89 of the hood carrier 37 is not arranged laterally offset radially to the receiving portion of the element hood 87. Rather, the mounting portion 89 extends in extension of the element cover 87 radially unopposed along the outer wall of the sheet metal pot 7 vertically downwards.
  • Fig. 5 is shown schematically in which area A, the heat conducting element 85 is thermally in contact with the underside of the hob plate 3.
  • the size of the surface is about 50 to 100 mm 2 .
  • the contact surface A is about 10 times larger than a base B of the temperature sensor 29. This ensures, inter alia, that the temperature at the bottom of the cooktop panel by the temperature sensor not quasi point-like, but determined integrating over a larger area becomes. This is particularly important because the respective pan diameter and its soil properties are not known exactly and can also vary from pan to pan type.
  • a lateral minimum distance a of the element 85 to the edge region of the insulating material 21 is about 8 mm.

  • the heat-conducting element 25 is still sufficiently thermally coupled to the region of the hob plate, which is heated directly by the heat radiation of the heating means 15. This is also achieved in the first and in the third embodiment, wherein at the same time the temperature sensor 29 relative to the hob plate 3 is covered by a grounded protective element 27 in compliance with the required according to 4 or 8 mm creepage and air gap.
  • the measuring surface A is coupled by a high-temperature lubricant to the cooktop plate underside, which consists in particular of glass ceramic material, in order to achieve improved heat transfer and impact resistance improved damping.

  • the control unit 101 regulates the heating power of the BandMapleiters 15 according to the measured values of the temperature sensor 29 to the predetermined by an input unit 103 target value. As a result, it can be achieved, in particular, that burning is virtually impossible during roasting.
