Abstract

A domestic refrigeration device includes a thermally insulated body with an internal compartment delimiting an interior coolable food storage space, a refrigeration apparatus cooling the interior space, a door leaf closing the interior space in a closed state and making the interior space accessible in an open state, and an interior lighting configuration illuminating the interior space with the door leaf open. The interior space has side walls with a depth, edges facing the door leaf, a ceiling and a rear wall rearwardly closing the interior space. The lighting configuration includes a first partial interior lighting configuration illuminating the interior space only at least approximately starting from a distance or space measured from the edges of the side walls facing the door leaf to the rear wall, and a second independent partial interior lighting configuration illuminating only a front region of the interior space facing the door leaf.

First claim

The invention claimed is:

1. A domestic refrigeration device, comprising:
a thermally insulated body having an internal compartment delimiting a coolable interior space for storing food products;
a refrigeration apparatus for cooling said coolable interior space;
a door leaf for closing said coolable interior space in a closed state and for making said coolable interior space accessible in an open state;
said coolable interior space including two opposing side walls having a depth and having edges facing said door leaf, a ceiling and a rear wall rearwardly closing off said coolable interior space;
an interior lighting configuration for illuminating said coolable interior space when said door leaf is open;
said interior lighting configuration including at least one first partial interior lighting configuration for illuminating said coolable interior space only at least approximately from a distance measured from said edges of said side walls facing said door leaf to said rear wall, when said door leaf is open; and
said interior lighting configuration including a second partial interior lighting configuration independent of said first partial interior lighting configuration for illuminating only a front region of said coolable interior space facing said door leaf, when said door leaf is open.

2. The domestic refrigeration device according to claim 1 , wherein said second partial interior lighting configuration is disposed in or on said ceiling.

3. The domestic refrigeration device according to claim 1 , wherein said at least one first partial interior lighting configuration is disposed in or on one of said two side walls at a distance from said edge of said one side wall facing said door leaf.

4. The domestic refrigeration device according to claim 3 , wherein said at least one first partial interior lighting configuration has an elongated lighting body radiating light into said coolable interior space when said door leaf is open.

5. The domestic refrigeration device according to claim 4 , wherein said elongated lighting body is disposed vertically in or on said one side wall.

6. The domestic refrigeration device according to claim 5 , wherein said elongated lighting body extends at least over a majority of a height of said one side wall.

7. The domestic refrigeration device according to claim 4 , which further comprises:
a plurality of shelves disposed on top of one another inside a part of said coolable interior space; and
at least one drawer disposed in a lower region of said coolable interior space;
said elongated lighting body being disposed vertically in or on said one side wall and extending at least over a majority of said part of said coolable interior space having said shelves.

8. The domestic refrigeration device according to claim 4 , wherein said lighting body radiates light into said coolable interior space entirely illuminating a region of said coolable interior space from said lighting body to said rear wall, when said door leaf is open.

9. The domestic refrigeration device according to claim 4 , wherein said lighting body radiates light into said coolable interior space and a portion of said radiated light radiates at right angles from said one side wall in a direction toward said coolable interior space.

10. The domestic refrigeration device according to claim 9 , wherein said radiated light radiates at a maximum angle of 100° measured from said one side wall in a direction toward said rear wall.

11. The domestic refrigeration device according to claim 4 , wherein said lighting body is a continuous optical waveguide with two ends, and said at least one first partial interior lighting configuration includes at least one lighting device.

12. The domestic refrigeration device according to claim 11 , wherein said at least one lighting device couples light produced by said at least one lighting device into said optical waveguide at least at one of said two ends.

13. The domestic refrigeration device according to claim 12 , wherein said optical waveguide uniformly distributes the light coupled therein.

14. The domestic refrigeration device according to claim 4 , wherein said lighting body includes a plurality of LEDs disposed in succession.

15. The domestic refrigeration device according to claim 14 , wherein said lighting body includes a base body to which said LEDs are fastened, said base body has a reflective side facing said LEDs, and said base body is shaped to cause light produced by said LEDs to entirely illuminate a region of said coolable interior space from said lighting body to said rear wall.

16. The domestic refrigeration device according to claim 14 , wherein light radiates from said coolable interior space, and a portion of the light radiating from said coolable interior space is bundled to radiate at right angles from one of said side walls in a direction toward said coolable interior space.

17. The domestic refrigeration device according to claim 16 , wherein the portion of the light radiating from said coolable interior space is bundled to radiate at a maximum angle of 100° measured from said one side wall in a direction toward said rear wall.

18. The domestic refrigeration device according to claim 1 , wherein said at least one first partial interior lighting configuration includes two first partial interior lighting configurations each being disposed in or on a respective one of said two side walls at a distance from a respective one of said edges of said side walls facing said door leaf.

19. The domestic refrigeration device according to claim 3 , wherein said second partial interior lighting configuration produces light illuminating only a front third of said coolable interior space.

20. The domestic refrigeration device according to claim 3 , which further comprises a sensor for identifying a brightness of surroundings of the domestic refrigeration device, said second partial interior lighting configuration being switched on only when the brightness of the surroundings of the domestic refrigeration device falls below a predetermined or predeterminable value, when said door leaf is open.
