Abstract

A dishwasher, in particular a household dishwasher, includes a washing compartment having a front access opening which is surrounded by a front frame. The front frame is open on a floor side and has lateral frame strips. A base support is arranged on the floor side and has bearing elements for support of the lateral frame strips. Each of the lateral frame strips of the front frame includes at least one hook element which encompasses the associated bearing element of the base support.

Claims

1. A dishwasher, comprising:

a washing compartment having a front access opening;

a front frame shaped and dimensioned to surround, at least in part, the front access opening, said front frame being open on a floor side, and said front frame having frame strips;

bearing elements to support corresponding ones of the frame strips; and

a base support arranged to support the washing compartment on a floor, the base support configured to support the bearing elements, and the bearing elements extending vertically from the base support,

wherein each of the frame strips of the front frame comprises at least one hook element structured to connect each of the frame strips to a corresponding one of the bearing elements of the base support at an upper edge of the corresponding bearing element,

wherein a longitudinal axis of each of the frame strips is parallel to a longitudinal axis of the corresponding one of the bearing elements,

wherein a vertical limb of each of the bearing elements overlaps an end of a corresponding base portion of each of the frame strips below the upper edge of the corresponding bearing elements when the frame strips are supported on the bearing elements,

wherein each of the frame strips comprises at least one height stop to support the front frame on the corresponding bearing element below the upper edge of the corresponding bearing element, and

wherein each of the frame strips comprises at least one depth stop to engage the corresponding bearing element in a depth direction below the upper edge of the corresponding bearing element.

2. The dishwasher of claim 1, wherein each of the frame strips of the front frame comprises at least one edge flange bent back from the base portion of the frame strip in a lateral direction relative to the washing compartment.

3. The dishwasher of claim 2, wherein the base portion of each of the frame strips of the front frame defines a transition with the at least one edge flange, and

wherein a downwardly open centering gap is provided at the transition to form the at least one hook element.

4. The dishwasher of claim 3, wherein the downwardly open centering gap comprises a widened insertion region with a chamfered edge, said widened insertion region comprising a wedge shape.

5. The dishwasher of claim 4, wherein the chamfered edge of the widened insertion region reduces a gap width of the centering gap approximately up to a wall thickness of the corresponding bearing element inserted into the centering gap.

6. The dishwasher of claim 1, wherein each at least one hook element comprises a hooked projection which merges with an angled hooked limb which is spaced apart by a clearance from the base portion of the corresponding frame strip to form a centering gap.

7. The dishwasher of claim 6, wherein the centering gap of each at least one hook element is downwardly open in a vertical direction for insertion of the upper edge of each of the bearing elements.

8. The dishwasher of claim 6, wherein in an assembled state the hooked projection is spaced apart from the upper edge of each of the bearing elements by a height difference.

9. The dishwasher of claim 1, wherein the at least one height stop is configured to support the front frame on a mating element of the corresponding bearing element.

10. The dishwasher of claim 9, wherein each of the bearing elements is provided with a height recess, said height recess having an edge to define the mating element, and the at least one height stop of each corresponding frame strip is structured to protrude into said height recess.

11. The dishwasher of claim 1, wherein the at least one depth stop is configured to engage a mating element of the corresponding bearing element in a depth direction.

12. The dishwasher of claim 11, wherein each of the bearing elements is provided with a depth recess, the depth recess having an edge to define the mating element, and the depth stop of the corresponding frame strip is structured to protrude into said depth recess.

13. The dishwasher of claim 1, further comprising a household dishwasher.

14. The dishwasher of claim 1, wherein each at least one hook element defines a clearance which corresponds approximately to a wall thickness of a region of each of the bearing elements encompassed by the hook element.

15. The dishwasher of claim 1, wherein the bearing elements are arranged outside of corresponding ones of the frame strips in a lateral direction relative to the washing compartment.

16. The dishwasher of claim 1, wherein each of the frame strips has a U-shaped cross-sectional profile.

17. The dishwasher of claim 1, wherein the bearing elements are positioned with a clearance in a lateral direction relative to the washing compartment and the bearing elements are secured in an assembled state only when the bearing elements are encompassed by the at least one hook element in the lateral direction.

18. The dishwasher of claim 1, wherein the longitudinal axis of each of the frame strips and the longitudinal axis of each of the bearing elements is perpendicular to the floor.

19. The dishwasher of claim 1, wherein the bearing elements are hinge plates, and wherein the dishwasher further comprises a door articulated to the hinge plates about a horizontal pivot axis.

20. The dishwasher of claim 1, wherein a longitudinal axis of each at least one hook element is parallel to the longitudinal axis of each of the frame strips and the longitudinal axis of a corresponding one of the bearing elements.

21. A frame assembly for a household appliance, the frame assembly comprising:

at least one frame strip comprising a hook element;

at least one bearing element; and

at least one base support to support the frame assembly on a floor, each at least one base support configured to support a corresponding one of said at least one bearing element,

wherein said hook element of each at least one frame strip is configured to engage the corresponding bearing element at an upper edge of the corresponding bearing element,

wherein a longitudinal axis of each of the at least one frame strip, a longitudinal axis of each hook element, and a longitudinal axis of each of the at least one bearing element is perpendicular to the floor,

wherein a vertical limb of each of the at least one bearing element overlaps an end of a corresponding one of the at least one base portion of each at least one frame strip below the upper edge of the corresponding bearing element when each of the at least one frame strip is supported on the corresponding bearing element,

wherein each at least one frame strip comprises at least one height stop to support the frame assembly on the corresponding bearing element below the upper edge of the corresponding bearing element, and

wherein each at least one frame strip comprises at least one depth stop to engage the corresponding bearing element in a depth direction below the upper edge of the corresponding bearing element.

22. The frame assembly of claim 21, wherein each hook element comprises a hooked projection which merges with an angled hooked limb which is spaced apart by a clearance from the at least one base portion of a corresponding one of the at least one frame strip to form a centering gap.

23. The frame assembly of claim 22, wherein the centering gap of each hook element is downwardly open in a vertical direction for insertion of the upper edge of each at least one bearing element.

24. The frame assembly of claim 21, wherein each of the at least one bearing element is a hinge plate configured to articulate a door of the household appliance about a horizontal pivot axis.

25. The frame assembly of claim 21, wherein each hook element defines a clearance which corresponds approximately to a wall thickness of a region of the at least one bearing element encompassed by the hook element.

26. The frame assembly of claim 21, wherein a longitudinal axis of each hook element, the longitudinal axis of each of the at least one frame strip, and the longitudinal axis of each of the at least one bearing element are perpendicular to the floor.
