Abstract
A cooking appliance including an interior, a fan mechanism having at least one fan wheel in the interior, at least one first flow directing member for subdividing the interior into a pressure chamber that houses the fan wheel and a cooking chamber, in which the first flow directing member includes at least one suction port for sucking atmosphere from the cooking chamber into the pressure chamber when the fan wheel is in operation and at least one blow-off port for blowing atmosphere from the pressure chamber into the cooking chamber when the fan wheel is in operation; and at least one second flow directing member that is included with the fan mechanism in the area of the suction port of the first flow directing member in order to improve the flow from the cooking chamber into the pressure chamber by forcing an axial main flow H in the suction zone of the fan mechanism, where the second flow directing member performs a nozzle function, extends from the fan mechanism into the cooking chamber, and overlaps the edge of the suction port of the first flow directing member, and where the first flow directing member extends into the second flow directing member.
