Abstract

A household refrigeration appliance having a receiving space for food and a plate-like lighting module for lighting the receiving space. The plate-like lighting module has a support apparatus, on which at least a light source module and a plate-shaped light guide are arranged. The support apparatus has a front frame which is a visible component of the lighting module facing the receiving space, and the front frame has a front strip, on the rear side of which a support web is arranged protruding backward and is formed in one piece with the front strip. The light source module is arranged on the support web.

First claim

The invention claimed is:

1. A household refrigeration appliance comprising:
a receiving space;
a plate-like lighting module for lighting said receiving space, said plate-like lighting module having a support apparatus, and a light source module and a plate-shaped light guide arranged on said support apparatus;
said support apparatus having a front frame, said front frame being a visible component of said lighting module facing said receiving space;
said front frame having a front strip, and a support web arranged on a rear side of said front strip and protruding backward from said front strip, and said support web being formed in one piece with said front strip; and
said light source module being arranged on said support web or on said rear side of said front strip; and
a first lateral edge region of said light guide facing said light source module and said first lateral edge region being configured for coupling a light of said light source module into said light guide through said first lateral edge region.

2. The household refrigeration appliance according to claim 1 , wherein said light source module is arranged on said support web and is covered by a partial region of said front strip toward said receiving space.

3. The household refrigeration appliance according to claim 1 , wherein said front frame is an external peripheral frame of said lighting module.

4. The household refrigeration appliance according to claim 1 , wherein said lighting module has a rear cover, said rear cover being a component separate from said front frame, and said rear cover being configured to cover a hole region surrounded by said front frame from behind.

5. The household refrigeration appliance according to claim 4 , further comprising a snap element, said snap element being snap fitted on said rear cover, and said snap element being integrally molded on said support web.

6. The household refrigeration appliance according to claim 4 , wherein:
said light guide is arranged between said front frame and said rear cover, and a partial region of said light guide extends by the first lateral edge region of said light guide into an intermediate space between said front strip and said rear cover.

7. The household refrigeration appliance according to claim 6 , wherein:
said light source module is arranged on said rear side of said front strip and said light guide has a front side and a first lateral edge region;
a depression is formed in a surface region of said front side, said surface region being adjacent to said first lateral edge region, and said light source module extending into said depression; and/or
said first lateral edge region is formed at least partially as a chamfer configured to reflect light that is coupled through said front side into said light guide from said light source module off said chamfer in said light guide.

8. The household refrigeration appliance according to claim 6 , wherein a second side wall region of said light guide is not configured for direct coupling-in of said light of said light source module, and a reflective element is arranged on said second lateral edge region.

9. The household refrigeration appliance according to claim 4 , further comprising an elastically compressible equalization mat arranged between said light guide and said rear cover.

10. The household refrigeration appliance according to claim 4 , wherein said rear cover has snap elements and said lighting module can be fixed to a wall of the household refrigeration appliance by a snap connection via said snap elements.

11. The household refrigeration appliance according to claim 1 , wherein a reflective structure is integrated on a rear side of said light guide facing away from said front strip or an additional reflective element is fixed to said rear side of said light guide facing away from said front strip.

12. The household refrigeration appliance according to claim 1 , wherein said lighting module has a diffusor plate, said diffusor plate at least partially covers said light guide viewed toward said receiving space.

13. The household refrigeration appliance according to claim 12 , wherein said diffusor plate, said light guide, and a reflective element fixed to a rear side of said light guide are connected in a material-bonded manner.

14. The household refrigeration appliance according to claim 1 , wherein said support apparatus has an interior frame separate from said front frame and said light guide and a rear cover of said lighting module are arranged on said interior frame 14 .

15. The household refrigeration appliance according to claim 14 , wherein said rear cover is connected to said interior frame by a snap connection.
