Definitions

  • the invention relates to a high-installation cooking appliance, with at least one muffle defining a cooking chamber with a bottom-side muffle opening and a bottom door with a hob on its upper side for closing the muffle opening.
  • DE 100 59 652 A1 is a high-installation cooking appliance in which in an open position of the bottom door a hob function and in a closed position a furnace function can be activated. Typically, a temperature of the cooking chamber in the closed state and a cooking state in the open state can be set.

  • the high mount cooker is equipped with at least two keep warm modes, namely, an open state keep warm mode and a closed state keep warm mode. It makes use of the fact that the hob in the open state can also be used as a bottom heat in the closed state and thus an immediate closing of the cooking chamber does not cool the food and a preheating can be omitted. This is also helped by the fact that the muffle is closed at the top so that heat rising from the hob and the food to be cooked immediately heats the cooking space. When opening, in turn, the food does not cool down immediately, nor does it need a separate cooking area be heated, still the food must be rearranged. This allows a user to easily and without preparation to use both warming modes to his advantage.
  • At least one hot air operation using a fan is favorably turned on.
  • the use of the radiator is flexible to the cooking appliance, the temperature or the court tunable. For example, bottom heat top and / or ring heater, possibly with a fan, are turned on.
