  • Patent number: 11249012
    Abstract: A domestic laundry-washing appliance including an optical measuring device for obtaining measured values which are representative of a spectral transmission signature of a washing liquid used during operation of the laundry-washing appliance for cleaning textiles, and a control device which is adapted to categorise a cleaning agent contained in the washing liquid in respect of its chemical properties on the basis of the spectral transmission signature obtained, and to control the operation of the laundry-washing appliance in dependence on the categorisation result. The categorisation result can indicate, for example, a distinction between a heavy-duty detergent containing bleach and another bleach-free detergent.

  • Patent number: 10962231
    Abstract: A pyrolytic oven comprises a housing and a muffle delimiting a cooking chamber inside the housing. A lighting module serves to illuminate the cooking chamber, wherein the lighting module has a cooling structure with an arrangement of cooling extensions formed in particular as pins or ribs, which project into a gap between housing and muffle and have a convection effect in a cooking mode of the oven. A fan device of the oven is configured and controlled to generate an air flow encountering the cooling structure in the gap in a pyrolytic mode of the oven. The cooling structure of the lighting module further has a wall formation, which in pyrolytic mode generates a wind shadow relative to the air flow for a number of cooling extensions of the cooling structure arranged distributed in a transverse plane to the flow direction of the air flow.

  • Patent number: 10928018
    Abstract: A light bar includes an arrangement of several light elements reciprocally spaced behind one another in the longitudinal bar direction where each light element produces a light beam, a reflection surface formed on a light-impermeable reflector body and producing a diffuse scattering effect where a first portion of the light beam of each light element is directed at the reflection surface, a light-permeable window element at which light produced by the light elements exits the light bar. A second portion of the light beam that is different from the first portion is directed past the reflection surface onto the light exit window. The light radiated by the light bar is composed of a direct light proportion and a scattered light proportion, the relative ratio of which in a suitable configuration of the reflector body and the window element can be different in different radiation directions of the light bar.

  • Patent number: 10724732
    Abstract: A lighting device for lighting an interior of a domestic electrical appliance is configured to be operated in different lighting modes which differ from one another by the spectral composition of the light of the lighting device delivered into the appliance interior. In some embodiments, the lighting device comprises two light-emitting diodes which differ from one another in terms of the spectral content of the light delivered thereby. The different lighting modes of the lighting device differ from one another by a different operating combination of the light-emitting diodes. By varying the duty cycle and the pulse frequency of a pulse-width-modulated control signal, a control assembly is able to transmit two different pieces of control information to the lighting module in order to control the two light-emitting diodes individually.

    Abstract: A washing machine includes a machine housing, a wash drum suspended by a plurality of carrier arms, a force sensor associated with at least one carrier arm provides a signal that is representative of a force acting on the carrier arm, and a control unit connected to the force sensor. The control unit receives measurement information during each of a plurality of phases of a program run of the washing machine, that is representative of a signal profile over time of the sensor signal over at least a portion of a revolution of the wash drum, introduces a defined amount of water into the wash drum between each pair of successive phases, determines parameter information indicative of the fabric type of laundry loaded into the drum based on the measurement information obtained during the various phases, and controls the program run in dependence on the determined parameter information.

  • Publication number: 20190338941
    Abstract: A domestic refrigerator includes an interior, a vertical side delimiting wall adjoining the interior, and a vertically elongate wall light arranged upright on the delimiting wall. The wall light includes a window pane which has surface profiling in a lower end portion of its pane length but is otherwise free of such surface profiling. Behind the window pane there is arranged a reflection surface which has a diffusely reflecting action for light emitted by a light source arrangement of the wall light in the direction towards to the light reflection surface, so that the light emitted by the wall light contains at least a significant proportion of scattered light. By means of the surface profiling, the light emission pattern of the wall light can be modified in some regions.
