ABSTRACT:
The disclosure relates to a fan impeller including a base plate and a plurality of fan impeller blades fixed to the plate. The fan impeller blades are positioned in an essentially vertical manner on the base plate and have a substantially radial arrangement, each fan impeller blade including a front edge facing radially outwardly that is substantially perpendicular to the base plate, a rear edge facing radially inwardly that is substantially perpendicular to the base plate, an exterior surface located on the delivery side of the fan impeller and an interior surface located on the intake side of the fan impeller. At least one raised element is mounted and/or configured on the exterior surface of at least one selection of the fan impeller blades, the element being positioned at a distance from the base plate and extending substantially in a diagonal manner away from the base plate from the front edge to the rear edge of the fan impeller blades. The disclosure also relates to a fan impeller in a cooking device and to a cooking device including at least one inventive fan impeller.
