  • the heaters should entirely abut against the upper panel thereabove, that are preferably made of glass so that heat loss is prevented, however cannot adhere to the upper panel since the temperature is high. Therefore, pressure is applied on the upper panel by means of the springs disposed on the lower panel.

  • the aim of the present invention is the realization of a cooking range comprising a lower panel wherein the deformation thereof due to the heat effect is reduced.
  • the cooking range realized in order to attain the aim of the present invention comprises a support made of a shape memory alloy (SMA) secured on the lower panel in the regions that might sag with the effect of heat, that applies a force in the opposite direction of the sagging to oppose the sagging that might form on the lower panel by changing shape with the effect of heat and prevents at least partially the deformation of the lower panel.
  • SMA shape memory alloy
  • the heaters are maintained to entirely abut with the upper panel by preventing the deformation of the lower panel due to effect of high temperatures originating from the long term operation of particularly the vitroceramic cooking ranges. Accordingly, the formation of gaps between the heaters and the upper panel by the deformation of the upper panel due to heat effect and thus the decrease in the cooking range efficiency or the temperature increase of the electrical or mechanical elements are prevented.
