Abstract

The present invention relates to a refrigerating and/or freezing device having a cooled interior chamber which comprises a recessed interior chamber portion, wherein the device has a lighting means and a light guide situated between the lighting means and a wall surface of the interior chamber portion, wherein the lighting means and the light guide are arranged in such a way that the light guide emits the light introduced by the lighting means into the interior chamber portion.

Claims

1. A refrigerator unit and/or a freezer unit comprising a cooled inner space that comprises a niche-like inner compartment section, characterized in that the unit has an illuminant and a light guide arranged between the illuminant and a wall surface of the inner compartment section, with the illuminant and the light guide being arranged such that the light guide emits the light introduced by the illuminant into the inner compartment section.

2. The refrigerator unit and/or freezer unit in accordance with claim 1, characterized in that the unit has at least two light guides that are connected to the illuminant and that are arranged such that they emit light introduced by the illuminant at different points into the inner compartment section.

3. The refrigerator unit and/or freezer unit in accordance with claim 2, characterized in that the illuminant has one or more individual light sources.

4. The refrigerator unit and/or freezer unit in accordance with claim 3, characterized in that the light sources are configured and arranged such that they introduce light of different intensity into the different light guides.

5. The refrigerator unit and/or freezer unit in accordance with claim 2, characterized in that the light guides are of different designs.

6. The refrigerator unit and/or freezer unit in accordance with claim 1, characterized in that the illuminant is arranged at a boundary wall of the inner compartment section with the boundary wall being able to be a section of the inner container.

7. The refrigerator unit and/or freezer unit in accordance with claim 6, characterized in that the illuminant is arranged asymmetrically with respect to the boundary surface of the inner compartment section corresponding to the boundary wall.

8. The refrigerator unit and/or freezer unit in accordance with claim 1, characterized in that the illuminant is arranged outside the inner compartment.

9. The refrigerator unit and/or a freezer unit in accordance with claim 1, characterized in that the inner compartment section is a tray such as a drawer, a niche formed by a molding of the inner container, or a storage tray at least partially separate from the remaining inner compartment.

10. The refrigerator unit and/or freezer unit in accordance with claim 1, characterized in that the unit is a domestic refrigerator.

11. The refrigerator unit and/or freezer unit in accordance with claim 3, characterized in that the light sources comprise LEDs, OLEDs, or lasers.

12. The refrigerator unit and/or freezer unit in accordance with claim 5, characterized in that the light guides are of different lengths.

13. The refrigerator unit and/or freezer unit in accordance with claim 8, characterized in that the illuminant is foamed in outside the inner compartment.

14. The refrigerator unit and/or freezer unit in accordance with claim 10, characterized in that the unit is a domestic refrigerator having one refrigerant circuit

15. The refrigerator unit and/or freezer unit in accordance with claim 10, characterized in that the unit is a combination refrigerator and freezer unit.

16. The refrigerator unit and/or freezer unit in accordance with claim 15, characterized in that the unit is a combination refrigerator and freezer unit.
