Definitions

  • the invention relates to an electrically heated roasting oven with bottom and top heating and with an integrated microwave device.
  • a roasting oven of this type is known from DE-OS 26 05 699.
  • the preparation or cooking of the food can take place in this roasting oven in a conventional manner by switching on the bottom and / or top heating of the roasting oven.
  • the bottom and / or top heating is additionally switched on to support it, in order to give the exterior of the item to be cooked a certain degree of browning and thus an improvement in taste.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of developing an electrically heated roasting oven of the type mentioned in such a way that the quality of the food to be cooked is improved and the cooking time is shortened.
  • the roasting oven housing 1 for a cooker has a known microwave device or heating 2 on its underside 1 'and a heating rod 3 arranged above it, which serves as an underheater.
  • the inner top side 1 "of the roasting oven housing 1 is a heating rod 4 and a further heating rod 5, which is used as additional heating, is provided between the latter.
  • a radiant panel 6 is arranged, which directs the radiant heat of the heating rods 4 and 5 down to the food to be fried.
  • the upper heat heating rod 4 and the lower heat heating rod 3 are connected in parallel and are controlled by an adjustable temperature controller 7 located in series with them.
  • the adjustable temperature controller 7 responds to the respectively set or preselected temperature for the roasting space of the roasting oven 1 and keeps the roasting space at this temperature.
  • the control range of this temperature controller 7 is in the range of about 50 0 to 300 ° C.
  • the top heat rod 4 and the bottom heat rod 3 can be switched on via a contact 8 which can be actuated by a switch toggle.
  • the additional heating rod 5 Parallel to the upper heat heating rod 4 and lower heat heating rod 3 is the additional heating rod 5, which is switched by a temperature switch 9 which is set to a temperature in the roasting chamber of approximately 250 ° C.
  • the additional heating element 5 is switched on via a switching element 10, which can be a conventional relay or an electronic or mechanical timer.
  • the temperature in the roasting chamber rises very slowly to 250 ° C. when only the upper heat heating element 4 and the lower heat heating element 3 are switched on.
  • the additional heater 5 is switched on, however, as the characteristic curve II shows, the desired temperature of 250 ° C. is set in the roasting chamber in a considerably shorter period of time, which is particularly the case with such a roasting oven when using the time-saving microwave device or heating when roasting or the like. is advantageous.
