Abstract: An optical waveguide device for guiding light emitted from a light source into an interior space of a household appliance includes an optical waveguide designed to emit light, introduced into the optical waveguide at a first end of the optical waveguide, to a second end of the optical waveguide. The optical waveguide has a cylindrical outer surface between the first end of the optical waveguide and the second end of the optical waveguide. A carrier is can be coupled directly or indirectly to the household appliance and includes an optical waveguide receptacle designed to receive the optical waveguide and to fix the optical waveguide axially and radially, said carrier connected to the optical waveguide by way of the outer surface, with the optical waveguide receptacle contacting the outer surface of the optical waveguide over a periphery of the optical waveguide.

Abstract: A cooking appliance apparatus includes a first cooking compartment, a second cooking compartment that is different from the first cooking compartment, an operating apparatus designed to set operating conditions for both the first cooking compartment and the second cooking compartment, and an illumination apparatus designed to illuminate the first and second cooking compartments in such a way that depending on for which one of the first and second cooking compartments the operating apparatus currently sets the operating conditions, only the one of the first and second cooking compartments is illuminated by the illumination apparatus with a specific identification illumination scenario.

Abstract: A food treatment appliance includes a muffle having a muffle interior. Arranged outside the muffle is a light-generating facility for radiating light into the muffle interior through an opening in the muffle. A light-distributing element is arranged in the muffle interior and configured to distribute light radiating in through the opening The light-generating facility and the light-distributing element are arranged such as to define a gap there between. The food treatment appliance can be applied to cooking devices having an oven functionality and/or microwave functionality.
