Abstract

A household appliance includes a cabinet-shaped housing comprised of a plurality of walls. At least one of the walls has an arrangement of embossings. The arrangement of embossings includes a first embossing arranged centered in relation to a center of the at least one wall and configured in the shape of a ring when viewed from above. A second embossing is arranged outside the first embossing in substantial concentric relationship to the first embossing and configured in the shape of a ring when viewed from above. At least one third embossing is arranged outside the second embossing and has a strip-shaped configuration. The presence of embossings in the at least one wall is able to reduce vibrations and thereby significantly reduce the amount of unwanted noise.

First claim

The invention claimed is:

1. A household appliance, comprising:
a cabinet-shaped housing comprised of a plurality of walls, at least one of the walls having an arrangement of embossings, said arrangement of embossings comprising:
a first embossing arranged centered in relation to a center of said at least one wall and configured in the shape of a ring when viewed from above,
a second embossing arranged outside the first embossing in substantial concentric relationship to the first embossing, said second embossing configured in the shape of a ring when viewed from above, and
at least one third embossing configured in the shape of a strip and arranged outside the second embossing,
wherein, as seen in cross section, the first, second and third embossings are formed by inwardly depressed curvatures, and each inwardly depressed curvature extends from a beveled edge,
wherein a maximum depth of each of the first, second and third embossings is defined by a depth of the respective beveled edge in addition to a depth of the respective inwardly depressed curvature.

2. The household appliance of claim 1 , wherein said at least one wall has two of said third embossing.

3. The household appliance of claim 2 , wherein the two third embossings are arranged point-symmetrically in relation to the center.

4. The household appliance of claim 2 , wherein one of the two third embossings is arranged above the second embossing and the other one of the two third embossings is arranged below the second embossing.

5. The household appliance of claim 1 , wherein two of the walls of the housing define rectangular side walls, at least one of the side walls including the arrangement of embossings.

6. The household appliance of claim 1 , wherein the first embossing, when viewed from above, is delimited by two ovals concentric and similar to one another to thereby establish a ring-shaped element with a constant width.

7. The household appliance of claim 1 , wherein the second embossing, when viewed from above, is delimited by two concentric and non-similar ovals to thereby establish a ring-shaped element with varying width.

8. The household appliance of claim 1 , wherein the third embossing, when viewed from above, has a substantially straight configuration.

9. The household appliance of claim 1 , wherein the third embossing is arranged in substantial concentric relationship to the second embossing and has the shape of a ring segment when viewed from above.

10. The household appliance of claim 1 , wherein the third embossing, when viewed from above, is formed from two parallel arcs having ends which are connected to one another to thereby establish an arc-shaped element.

11. The household appliance of claim 1 , wherein the third embossing, when viewed from above, is formed from a segment of two intersecting, non-similar ovals to thereby establish an arc-shaped element which is wider in midsection than at ends thereof.

12. The household appliance of claim 1 , wherein the first, second and third embossings, when viewed from above, occupy around 40% of a surface of said at least one wall.

13. The household appliance of claim 1 , wherein said at least one wall has a non-embossed surface encircled by the first embossing and defined by a diameter which corresponds to approximately one third of a width of said at least one wall.

14. The household appliance of claim 1 , wherein each of the first, second and third embossings has a maximum depth which amounts to around three times to four times a thickness of said at least one wall.

15. The household appliance of claim 1 , wherein the first embossing is delimited by two concentric circles, and
the second embossing is delimited by an inner circle and an outer shape, the outer shape being formed from a circle that is truncated by two parallel straight sections.

16. The household appliance of claim 15 , wherein the two parallel straight sections are parallel to edges of the at least one wall.

17. The household appliance of claim 16 , wherein the third embossing, when viewed from above, is formed from two parallel arcs having ends which are connected to one another to thereby establish an arc-shaped element.

18. The household appliance of claim 15 , wherein the third embossing, when viewed from above, is formed from two parallel arcs having ends which are connected to one another to thereby establish an arc-shaped element.

19. The household appliance of claim 1 , wherein each said beveled edge is inwardly angled relative to an exterior of the at least one wall, and each said inwardly depressed curvature has a radius of curvature extending from and between the respective beveled edges.

20. The household appliance of claim 1 , wherein the inwardly depressed curvature of the second embossing has a variable width.

21. The household appliance of claim 20 , wherein the width is greater towards corners of the wall.

22. The household appliance of claim 1 , wherein the third embossing has end portions and a middle portion, wherein a width of the middle portion of the inwardly depressed curvature of the third embossing is greater than a width of the end portions.

23. The household appliance of claim 1 , wherein each beveled edge extends from a first bending point having a radius of curvature, the first bending point transitioning from an exterior surface of the wall to the respective beveled edge.

24. The household appliance of claim 23 , further comprising a second bending point between each beveled edge and its respective inwardly depressed curvature, the second bending point having a second radius of curvature.

25. The household appliance of claim 24 , wherein the first and second radius of curvature are different than one another.

26. The household appliance of claim 25 , wherein the first radius of curvature is greater than the second radius of curvature.

27. The household appliance of claim 1 , wherein the depth of each said inwardly depressed curvatures is greater than the depth of the beveled edge.

28. The household appliance of claim 1 , wherein the depth of each said inwardly depressed curvatures is at least two times greater than the depth of the beveled edge.

29. The household appliance of claim 1 , wherein the depth of each said inwardly depressed curvatures is about five times greater than the depth of the beveled edge.

30. The household appliance of claim 1 , wherein the beveled edges of the first, second and third embossings are identical.

31. The household appliance of claim 1 , wherein each beveled edge of the first, second and third embossings extends at a bevel angle with respect to an unembossed surface, and each of said inwardly depressed curvatures extends at a curvature angle with respect to the unembossed surface, and wherein the bevel angle of the first, second and third embossings is greater than the angle of each of said inwardly depressed curvatures.
