a housing with a tank arranged to receive food to be cooked and/or reheated,
a removable cover arranged to close the tank while cooking and/or reheating,
at least one heating element and a fan arranged to create a closed hot air flow while cooking and/or reheating,
a ventilation sheath comprising a suction inlet arranged on one side of the tank, a ventilation outlet above the tank and arranged downwards to direct the hot air flow directly onto the food while cooking and/or reheating when the tank is closed by the cover, wherein the ventilation sheath is in one piece and separated from the cover,
wherein the ventilation sheath is directly fastened only onto the housing of the tank and not integrated in the cover so that the cover does not have any air channeling element that channels heated air flow onto the food in the tank.
