  • Patent number: 11889965
    Abstract: A mechanism for the door of a domestic electrical appliance, for example a dishwasher, is described. The mechanism includes a door latch for holding the door closed, a latch opener mechanism, an electrically controlled actuator for displacing the latch opener mechanism, a movably arranged pusher, and a spring device for providing a spring force which acts on the pusher. The latch opener mechanism functions such that, when the door is closed, it can be transferred from an inactive position into an active position while at least partially overcoming a holding-closed action of the door latch. The movably arranged pusher is separate from the latch opener mechanism and is decoupled therefrom in terms of movement. After the holding-closed action of the door latch has been overcome, the spring drive allows the door to be pushed open by the pusher.

  • Patent number: 11891838
    Abstract: A door lock for a domestic electrical appliance such as, for example, a washing machine of the top loader type includes a lock module, a housing shell for the floating mounting of the lock module on a housing wall portion of a body of the domestic appliance, a locking member which is arranged to be movable between an unlocking position and a locking position, and an electrically controllable actuator for actuating the locking member. The lock module has an insertion opening for insertion of a closing element on closing of the door of the domestic appliance. The locking member in its unlocking position allows the closing element to move out of the insertion opening and in the locking position effects blocking of the closing element against moving out of the insertion opening. At least one centring slope for the closing element is formed at the insertion opening.

  • Patent number: 11879788
    Abstract: A sensor suitable for optical turbidity measurements is described. The sensor is suitable for use in a water-bearing domestic electrical appliance (e.g. washing machine or dishwasher) and allows the temperature dependence of the turbidity measurements obtained by means of a first light detector to be compensated for. To this end, the sensor implements, in addition to a turbidity-measuring path along which a measuring-light beam is sent through a measuring space containing the turbid medium to a first light detector, a reference measuring path along which a reference light beam is transported to a second light detector which is thermally coupled with the first light detector. A heat-equalizing element can ensure that any temperature differences between the two light detectors are minimized. Both light-measuring paths can run in some regions inside the same solid-material light-conducting structure.

  • Publication number: 20240011327
    Abstract: A domestic electrical appliance, for example a dishwasher, is disclosed, in which a door latch is installed in a profile strip of an appliance body. The door latch comprises a latch housing in which, in some embodiments, a rotary gripper and a leg-torsion spring serving as a closing spring are accommodated. In one embodiment, the door latch as a whole is displaceable in the profile strip in the strip longitudinal direction thereof in order to implement a self-healing function which allows the door to close even after the door latch has moved into a closed state without the door being closed. In another embodiment, a housing main part of the latch housing is mounted in a longitudinally fixed manner on the profile strip, but a housing cover of the latch housing is longitudinally displaceable relative to the housing main part, and the torsion spring and the rotary gripper are held on the housing cover.

  • Patent number: 11800964
    Abstract: A turbidity sensor for a water-bearing domestic appliance includes a sensor housing having a housing main part and two housing projections protruding from the housing main part side by side and at a distance from one another, where the two housing projections delimit between them a measuring channel for a liquid to be measured. One of the housing projections emits a measuring light beam along a measuring path which runs transversely through the measuring channel to the other housing projection. The measuring path crosses the measuring channel in the channel longitudinal direction remote from a point of smallest channel width of the measuring channel or the measuring channel has a constriction at a longitudinal distance from its longitudinal midpoint, at which constriction the channel width is smaller than in a region of a longitudinal midpoint.

  • Patent number: 11781345
    Abstract: A door latch for a domestic electrical appliance wherein the door latch comprises a rotary gripper which, on closing of a door, can be transferred from a release position into a gripping position by rotation in a rotational plane, and an electrically controllable locking mechanism having a movably arranged blocking element which, in the gripping position of the rotary gripper, can be fixed in a blocking position in which the blocking element cooperates with the rotary gripper to block the movement of the rotary gripper both from the gripping position into the release position and from the gripping position into a yielding position. The rotary gripper forms a gripping mouth which in the gripping position is oriented to hold captive a closing shackle which, on closing of the door, moves relatively closer to the rotary gripper along a closing path and arranged for a yielding movement into the yielding position.

  • Patent number: 11624209
    Abstract: A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

  • Patent number: 11434662
    Abstract: A door latch for an electrical domestic appliance includes a rotary member arranged to be rotationally movable between a closing rotational position and a release rotational position and is spring-biased in the direction towards the release rotational position, a movably arranged catch that is in an arresting engagement with the rotary member when the rotary member is in the closing rotational position, and a locking assembly that includes a movable locking member movable between an unlocking position and a locking position. The arresting engagement is releasable by an overlifting rotational movement of the rotary member. The rotary member is rotationally movable between a closing rotational position and a release rotational position and is spring-biased in the direction towards the release rotational position. The locking member, when transferred from the unlocking position into the opening position, causes the arresting engagement of the catch with the rotary member to be released.
