  • a cooking oven is known from DE 33 46 019 C2 , in which the oven muffle can be heated both by electric radiant heaters (top heat and bottom heat) and by a microwave generator.
  • the furnace muffle On its muffle ceiling, the furnace muffle has a vapor opening in a front area facing the door, in which a catalytic afterburner in the form of a porous vapor stone is arranged.
  • a fan wheel with fan blades pointing downwards towards the vapor opening which is arranged in a suction chamber enclosed by a fan housing and, as a radial fan, sucks the air passing through the vapor stone axially out of the muffle interior and blows it out radially through a side outlet opening in the fan housing ,
  • the fan wheel is driven by an electric drive motor via an axis.
  • the vacuum suction fan formed in this way by the fan wheel, drive motor and fan housing is only switched on when the microwave generator is in operation.
  • an air inlet opening is provided below the furnace door, through which air can flow into the muffle interior.

  • the outlet opening of the vapor suction fan also opens into this ventilation channel, so that the vapor extracted and cleaned by the catalytic converter is blown out to the front with the cooling air. Condensation of vapors on the inside of the furnace door is prevented by the air flow along the furnace door that arises within the muffle.

Energy is saved by recycling the cleaned exhaust air.
