To illuminate a structure 5 with informational content on components 3, 20 of a filling opening in a laundry appliance, particularly a washing machine or a washer/dryer, components 3, 20, which are made of a transparent or translucent material, have a pot-shaped laundry deflector 20 and a window cover 3 lying at least approximately flush with the front face 1 of the laundry appliance. Components 3, 20 bear lettering 4, 16 and/or a symbol to be illuminated. Light-emitting elements 6, 17 are arranged opposite lateral edge faces 10, 15 of at least one of the components 3, 20, the light beams 9, 19 emitted by said elements being directed onto the edge faces 10, 15. The lettering 4, 16 or the symbol consists of a three-dimensional structure 5 in the material with an at least microscopically small extension into the material. To specify a structural illumination in which a lower number of light sources is adequate, one of the components 3, which is located at least approximately flush with the front face 1 of the laundry appliance and which is provided with the structure 5, 16, has a light-conducting element 13 extending inwards away from the flush line, the light inlet area 15 of which element extends as an edge face to the other component 20 and is guided into the radiation range of the light-emitting element 17.
A lighting device on a laundry care appliance, the laundry care appliance comprising a loading opening and components made of a transparent or translucent material in the form of a pot-shaped laundry deflector and a window cover covering the loading opening lying at least approximately flush with the front face of the laundry care appliance, which bears lettering or a symbol, the lighting device comprising light-emitting elements arranged opposite lateral edge faces of at least one of the components, the light beams emitted by said elements being directed onto the edge faces and the lettering or symbol consisting of a three-dimensional structure in the material with an at least microscopically small extension into the material, wherein one of the components, which lies at least approximately flush with the front face of the laundry care appliance and is provided with the structure, has a light-conducting element that reaches inward out of the flush line, its light entry face reaching to the other component in the manner of an edge face and being guided into the radiation region of the light-emitting element.
A lighting device on a laundry care appliance, the laundry care appliance comprising a loading opening and components made of a transparent or translucent material in the form of a laundry deflector and a window cover covering the loading opening lying at least approximately flush with the front face of the laundry care appliance, which bears a three-dimensional structure, the lighting device comprising light-emitting elements arranged opposite lateral edge faces of at least one of the components, the light beams emitted by said elements being directed onto the edge faces and the-three-dimensional structure is provided with an at least microscopically small extension into the material, wherein one of the components, which lies at least approximately flush with the front face of the laundry care appliance and is provided with the structure, has a light-conducting element that reaches inward out of the flush line, its light entry face reaching to the other component in the manner of an edge face and being guided into the radiation region of the light-emitting element.
