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.

Abstract: A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is mounted within the wash tub for taking images of the load of clothes during and/or after a wash or rinse cycle. A controller is operably coupled to the camera for obtaining and analyzing the images using a neural network image recognition process (such as an R-CNN process) to determine a whether the level of suds or bubbles exceeds a suds threshold. If there are too many suds in the wash tub, the controller may implement corrective action, e.g., by decreasing a water temperature, adding more water, or reducing the amount of detergent that is auto-dispensed in a subsequent wash cycle.

Abstract: A washing machine has a suds container arranged in a housing, in which container a drum is rotatably mounted, a loading opening arranged on the front of the housing which can be closed by a door having a door inspection glass, a door sealing ring that extends between the housing and the suds container around the loading opening, and a control or regulating device. The washing machine is configured for carrying out a selected washing program including a rinsing phase and a step, in which water is applied to the door inspection glass and the door sealing ring following the rinsing phase to rinse the door inspection glass and the door sealing ring. The washing machine performs a spin cycle after the rinsing phase and before applying water to the door inspection glass and the door sealing ring at a maximum speed as a function of the selected washing program.
