  • FIG 3 clarifies the structure of the heating plate. The top panel 10, the graphite layer 12, the heating panel 14 and the supporting plate 16 are arranged one upon the other.
  • The temperature sensor element 20 is formed as a mushroom. The head of the mushroom-shaped temperature sensor element 20 is pressed against the bottom side of the top panel 10. The shaft of the mushroom-shaped temperature sensor element 20 penetrated through the heating panel 14 and the supporting plate 16. Thus, the temperature sensor element 20 is directly pressed by the by the heating panel 14, and indirectly pressed by the pressing disc 18 via the supporting plate 16 against the top panel 10. The pressing discs 18 are fastened at the supporting plate 16 by the fastening bolt 22 and a screw nut 24 in each case, wherein the fastening bolts 22 penetrates through the corresponding round holes 28 in the supporting plate 16.

Thus, the head of the mushroom-shaped temperature sensor element 20 is arranged above the supporting plate 16 and heating panel 14, when the temperature sensor element 20 is fixed at the heating plate. Since the supporting plate 16 and heating panel 14 are pressed against the top panel 10, the temperature sensor element 20 is also pressed against the top panel 10.
  • FIG 5 illustrates a detailed schematic perspective top view of the temperature sensor element 20 of the heating plate according to the preferred embodiment of the present invention. FIG 5 clarifies the arrangement of the head of the mushroom-shaped temperature sensor element 20.
  • Unlike the supporting plate 16 and the heating panel 14 comprising the keyhole 26, the graphite layer 12 comprises a long hole or slot provided for the head of the mushroom-shaped temperature sensor element 20. The height of the head of the mushroom-shaped temperature sensor element 20 is adapted to the thickness of the graphite layer 12. Thus, the head of the mushroom-shaped temperature sensor element 20 is clamped between the top panel 10 and the heating panel 14. The temperature sensor element 20 is from-locked and friction-locked fasted at the heating plate.
  • The arrangement of the temperature sensor element 20 allows a direct and exact measuring of temperature at the top panel 10. The temperature sensor element 20 does not require any special fastening means. The temperature sensor element 20 is clamped by the pressing discs 18, which are already provided for fastening the heating panel 14 or the heating elements, respectively.
