Lighting device for a household appliance having a treatment chamber

A lighting device for a household appliance with a treatment chamber, the lighting device comprising:

• at least one light channel disposed in a wall of the treatment chamber or a door of the treatment chamber;
• at least one light source disposed on the household appliance outside of the treatment chamber, the light source cooperating with the at least one light channel and operable to provide light beams along a first direction;
• a first reflector disposed in the at least one light channel operable to reflect a first portion of the light beams toward the treatment chamber so as to enter the treatment chamber through a transparent area in the wall or door of the treatment chamber,
• a second reflector disposed in the at least one light channel operable to reflect a second portion of the light beams toward the treatment chamber so as to enter the treatment chamber through the transparent area, the second reflector being further from the light source in the first direction and extending farther in a second direction transverse to the first direction, than the first reflector, such that the second portion of the light beams reach the second reflector in an unhindered manner;
• a first reflective surface disposed on the first reflector and having a configuration in the second direction and a third direction transverse to the first direction;
• and
• a second reflective surface disposed on the second reflector, the second reflective surface having a configuration in the second direction and the third direction, the configuration of the second reflective surface being different from the configuration of the first reflective surface in both the second and third directions so as to avoid shadowing of the second reflective surface by the first reflective surface.
