Optical waveguide device for a cooking appliance

An optical waveguide device for guiding light emitted from a light source into an interior space of a household appliance, in particular a cooking chamber of a cooking appliance, the optical waveguide device comprising:

• 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, said optical waveguide having a cylindrical outer surface between the first end of the optical waveguide and the second end of the optical waveguide;
• and
• a carrier capable of being directly or indirectly coupled to the household appliance and comprising 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,
• wherein the optical waveguide receptacle of the carrier and the optical waveguide are connected by a thermal press fit connection so as to fix the optical waveguide in the carrier exclusively by a force-fit connection.
