Definitions

  • the invention relates to a baking oven with a cooking chamber which can be closed by a furnace door preferably having a see-through window and which is heatable by at least one heating element arranged outside, preferably below the cooking space.
  • the present invention has for its object to provide an oven of the type mentioned in such a way that without affecting the internal and / or external thermal energy operation fogging the particular designed as a transparent window inner surface of the oven door and thus their viewing obstructing condensation of process air (vapor) This inner surface can be avoided.
  • the at least one radiator is preferably connected by a heat conduction device with the oven door surface delimiting the cooking chamber whose inner surface to their heating.
  • the heat energy of the outside of the cooking chamber arranged radiator preferably the so-called bottom heat is used to preferably to heat the inner surface of the oven door to a temperature which at least approximately corresponds to the cooking temperature prevailing in the oven during cooking operation.
  • this door surface which is usually the coolest cooking space limit without this measure, heated to a temperature that prevents condensation of humid moisture without additional ventilation measures and in the case of a see-through window in the oven door allows full visibility.
  • the bottom heat is not delivered to the outside furnace housing parts, but introduced into the cooking process within the cooking chamber.
  • Effective heat conduction from the outside of the cooking chamber arranged radiator to the oven door surface can be made according to the invention that the heat conducting device is formed by the heated air from the radiator to the furnace door surface conductive air guide elements, for this purpose, a fan may be provided for the air flow.
  • a cooling device is provided for dissipating the heat prevailing in the outer region of the oven during cooking operation, which can be used according to the invention that a partial flow of a cooling air blower of the oven is provided for the air flow for heating the inner surface of the oven door.
  • the difference between the air pressure between the space containing the radiator and the cooking chamber is effective as a heat conducting device.
  • a heat transfer from the outside radiator to the surface of the oven door is made possible without additional design measures.
  • the so-called bottom heat of the oven is used as a heat source for heating the furnace door surface, which is anyway provided in conventional ovens for heating the cooking chamber from below.
  • the oven according to the figures has a cuboid cooking chamber 1, the feed opening is closed by an oven door 2 and in the closed position at a z.
  • B. circumferential seal 3 abuts the cooking chamber 4.
  • the oven door 2 has a see-through window formed of glass panes whose inner glass pane 5 delimits the cooking space 1 with the inner surface 6.
  • a baffle 7 At the rear of the cooking chamber 1 is located behind a baffle 7, a circulating air fan 8 with a ring heater.
  • Below the cooking chamber 9 is arranged a, a so-called bottom heat performing outdoor radiator 10.
  • the space 11 between the cooking chamber 9 and a lower housing or cooking chamber part is connected by ventilation to an exemplary only indicated fan 13 z.
  • a cooling fan which may be located outside of the cooking chamber 1, for example, in an upper switch room of the oven and may be connected to an air duct to the room 11.
  • a cooling fan which may be located outside of the cooking chamber 1, for example, in an upper switch room of the oven and may be connected to an air duct to the room 11.
  • At the front end of the room 11 are directed in the direction of the oven door 2 flow openings 14 z. B. in the form of several recesses in the cooking chamber bottom 9.
  • These flow openings 14 form a heat conducting device for the transmission of the outgoing heat from the radiator 10 to the inner surface 6 of the oven door second
  • the oven door 2 When cooking, ie at high cooking temperature in the cooking chamber 1, the oven door 2 is usually the coolest boundary of the cooking chamber 1, associated with a condensation of the wet Wrasens on the inner surface 6 of the oven door 2 and with a hindrance of the view through the window.
  • a heat conducting device can also be designed in a different manner than described, for. B. by natural Lucaskonvelement between the space 11 and the cooking chamber 1, favored by a suction effect between the space 11 and a lower air pressure in the cooking chamber 1 or by means of a mechanical z. B. foil-like heat transfer between room 11 and oven door. 2
