Patent attributes
In a method for improved fresh air supply in a cooking apparatus, an inner housing is provided to circumscribe a cooking chamber. A fan chamber is separated from the cooking chamber via at least one flow guide element. The fan chamber has a fan with a fan wheel which comprises primary blades on its side facing the first flow guide element and auxiliary blades on its side facing the wall of the inner housing through which the axle of the fan wheel passes to connect with a motor arranged outside of the inner housing. The fan wheel is provided for the circulation of cooking atmosphere and/or suction of fresh air into the inner housing via a fresh air channel, a mouth of which is separated from the axle of the fan wheel and runs into the inner housing through the wall. Fresh air sucked in through the fresh air channel is initially conducted via at least a second flow guide element which prevents a direct impingement of the fresh air on the auxiliary blades and prevents an angular momentum effect by the auxiliary blades from being imparted on the fresh air. The fresh air then is conducted from the axle of the fan wheel into the cooking chamber via the radial guiding or conveying effect of the auxiliary blades.
