Abstract: An air-flap device for a refrigerator and/or freezer for equipping a kitchen comprises an air flap (18) which is mounted so as to be pivotable about a first axis of rotation (20) between an open position and a closing position and which, in the open position, unblocks an air-passage aperture (16) for the passage of air and, in the closing position, blocks said air-passage aperture, at least substantially, against the passage of air, and said air-flap device also comprises a motorized flap-actuating mechanism for displacing the air flap in a pivoting manner. According to the invention, the flap-actuating mechanism comprises a movably disposed flap-actuating element (26) having a flap-engaging section (32) which can be moved, as a result of movement of said flap-actuating element, from outside the pivoting space of the air flap into said pivoting space in order, in doing so, to pass into engagement with the air flap and lift the latter out of one of the two flap positions towards the other.

Abstract: An optical sensor to measure the turbidity of wash water in a household washing machine or dishwasher, includes a housing having a housing interior containing a measurement module having a light-emitting element and a light-receiving element, the measurement module defining a measurement light path which extends from the light-emitting element to the light-receiving element and passes outside the housing over a part of its path length. The light-emitting element and the light-receiving element are arranged together in a first subspace of the housing interior, and the measurement light path extends over a part of its path length through at least one second subspace of the housing interior, which is sealed from the first subspace. All the electrical/electronic components of the measurement module are fitted in the first subspace, so that any ingress of wash water into the second subspace does not compromise the electrical functionality of the sensor.

Abstract: An ice chute arrangement that includes a fixed frame adjacent to an ice passageway. A flap is pivotal upon the frame between a first flap position and a second flap position. The flap blocks the ice passageway when the flap is in the first position, reveals the passageway when the flap is in the second position and transitions through an intermediate position. The arrangement includes a paddle pivotal upon the frame between a first position and a second position. The paddle causes the flap to pivot from the first position to the second position as the paddle pivots from the first position to the second position. The arrangement includes a first spring that biases the flap toward the first flap position while the flap is in the first flap position and biases the flap toward the second flap position while the flap is in the second flap position.

Abstract: A door latch for an electrical household appliance includes a closing spring arrangement which is tensioned in an open position of the door latch and relaxes upon closing of the door, and a gripping unit which grips a closing element upon closing of the door and releases it again upon opening of the door. The gripping unit in the open position of the door latch is in blocking engagement with a blocking element owing to the force of the closing spring arrangement. The closing element upon the closing of the door causes a rotary movement of the gripping unit about an axis of rotation where the gripping unit comes out of blocking engagement with the blocking element enabling a relaxation of the closing spring arrangement. The force of the relaxing closing spring arrangement causes a subsequent pull-shut movement of the gripping unit. The gripping unit has a base body bearing at least one supporting projection, projecting coaxially with respect to the axis of rotation, for supporting the gripping unit.
