Flow directing device for a cooking appliance

摘要

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.

1. A cooking appliance comprising:
an interior; a fan mechanism including at least one fan wheel in the interior; at least one first flow directing member for subdividing the interior into a pressure chamber that includes the fan wheel and a cooking chamber, wherein 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 affixed to the fan mechanism or molded 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 in the suction zone of the fan mechanism, wherein the second flow directing member performs a nozzle function, reduces the volume of counterflow into the cooking chamber by extending from the pressure chamber into the cooking chamber, and overlaps an edge of the suction port of the first flow directing member, an opening formed between the first flow directing member and the second flow directing member that connects the cooking chamber and the pressure chamber, wherein the first flow directing member extends into the second flow directing member, and wherein the first flow directing member comprises an air directing plate that extends from the suction port and ends before the at least one blow-off port which forms a gap on an outer edge of the air directing plate.
