Abstract
An air flap device (10) for a cooling or/and freezing appliance of kitchen equipment comprises an air flap (18) which is mounted so that it can pivot about a first axis of rotation (20) between an open position and a closed position, uncovers an air passage opening for the passage of air in the open position and at least substantially blocks the air passage opening against the passage of air in the closed position, and a motor-driven flap operating mechanism for pivoting the air flap. According to the invention, the flap operating mechanism comprises a rotary member (26) which is disposed so as to be driven about a second axis of rotation (28) as well as a separate force transmission member (32) which serves to transmit force between the rotary member and the air flap, is coupled to the rotary member at a point lying eccentrically to the second axis of rotation and is coupled to the air flap (18) at a point lying at a distance from the first axis of rotation.
