Abstract

A dishwasher, in particular a household dishwasher, includes at least one wash compartment and a rack guide rail for support in the wash compartment of a rack which holds items to be washed and/or dried. The rack guide rail has a running surface to allow movement of the rack in and out of the wash compartment for loading and unloading purposes along a travel path supported on the running surface. The rack guide rail is hereby supported at a support point for pivoting about a pivot axis.

First claim

What is claimed is:

1. A dishwasher, comprising:
at least one wash compartment; and
a rack guide rail for support in the wash compartment of a rack which holds items to be washed and/or dried, said rack guide rail having a running surface to allow movement of the rack in and out of the wash compartment for loading and unloading purposes along a travel path supported on the running surface, said rack guide rail being supported at a first support point for pivoting about a pivot axis, wherein the travel path extends at a sloped angle relative to horizontal to allow for gravity-assisted movement into and/or out of the wash compartment.

2. The dishwasher of claim 1 , constructed in the form of a household dishwasher.

3. The dishwasher of claim 1 , wherein the rack guide rail is pivotable about the pivot axis to move the running surface into an oblique position defined by a gradient that allows the rack to move into and/or out of the wash compartment due to gravity.

4. The dishwasher of claim 1 , wherein the running surface is lowerable at least partially to change a slope of the running surface.

5. The dishwasher of claim 1 , wherein the rack guide rail has a second support point at least on one of its end segments.

6. The dishwasher of claim 1 , wherein the pivot axis is defined by a rotation point which is disposed in a center region of a longitudinal extension of the wash compartment in a direction of the travel path.

7. The dishwasher of claim 1 , wherein the rack guide rail has a roller guide, which has at least one fixed first roller having an axis of rotation, said axis of rotation forming the pivot axis.

8. The dishwasher of claim 7 , further comprising a housing, said first roller being supported rotatably on the housing.

9. The dishwasher of claim 8 , wherein the roller guide has a second roller which is supported for displacement heightwise on the housing to guide the rack guide rail.

10. The dishwasher of claim 9 , wherein the second roller is disposed at a distance from the first roller in a direction of the travel path.

11. The dishwasher of claim 1 , further comprising an actuator for at least partial lowering of the travel path.

12. The dishwasher of claim 11 , wherein the actuator is actively connected to the rack guide rail.

13. The dishwasher of claim 9 , further comprising an actuator for at least partial lowering of the travel path, said actuator being actively connected to the second roller.

14. The dishwasher of claim 1 , further comprising at least one member selected from the group consisting of at least one eddy current brake, a gas pressure damper facility, and a hydraulic damper facility to slow down a rack movement brought about by pivoting.

15. The dishwasher of claim 1 , wherein the running surface is constructed to allow at least partial raising thereof.

16. A rack guide rail for a dishwasher, said rack guide rail supporting in a wash compartment of the dishwasher a rack which holds items to be washed and/or dried, said rack guide rail having a running surface to allow gravity-assisted movement of the rack in and/or out of the wash compartment for loading and/or unloading purposes along a travel path supported on the running surface, said rack guide rail being supported at a first support point for pivoting about a pivot axis to enable said rack guide rail to be sloped relative to horizontal.

17. The rack guide rail of claim 16 , wherein the rack guide rail is pivotable about the pivot axis to move the running surface into an oblique position defined by a gradient that allows the rack to move into and/or out of the wash compartment due to gravity.

18. The rack guide rail of claim 16 , wherein the running surface is lowerable at least partially to change a slope of the running surface.

19. The rack guide rail of claim 16 , further comprising a second support point at least on an end segment of the rack guide rail.

20. The rack guide rail of claim 16 , wherein the pivot axis is defined by a rotation point which is disposed in a center region of a longitudinal extension of the wash compartment in a direction of the travel path.

21. The rack guide rail of claim 16 , further comprising a roller guide, which has at least one fixed first roller having an axis of rotation, said axis of rotation forming the pivot axis.

22. The rack guide rail of claim 21 , wherein the first roller is supported rotatably on a housing of the dishwasher.

23. The rack guide rail of claim 21 , wherein the roller guide has a second roller which is supported for displacement heightwise on a housing of the dishwasher to guide the rack guide rail.

24. The rack guide rail of claim 23 , wherein the second roller is disposed at a distance from the first roller in a direction of the travel path.

25. The rack guide rail of claim 16 , further comprising an actuator for at least partial lowering of the travel path.

26. The rack guide rail of claim 25 , wherein the actuator is actively connected to the rack guide rail.

27. The rack guide rail of claim 23 , further comprising an actuator for at least partial lowering of the travel path, said actuator being actively connected to the second roller.

28. The rack guide rail of claim 16 , further comprising at least one member selected from the group consisting of at least one eddy current brake, a gas pressure damper facility, and a hydraulic damper facility to slow down a rack movement brought about by pivoting.

29. The rack guide rail of claim 16 , wherein the running surface is constructed to allow at least partial raising thereof.
