Abstract

A household appliance includes appliance walls which delimit a space. A covering plate is arranged on an outer face of at least one of the appliance walls so as to leave free a gap. The gap is sealed in an edge region of the covering plate by an acoustic sealing frame.

11. The household appliance of claim 1, wherein the acoustic sealing frame is fixed to the appliance wall or to an anti-drumming layer provided on the appliance wall by at least one of mechanical securement and gluing.

12. The household appliance of claim 1, wherein the covering plate is fixed to the acoustic sealing frame by at least one of mechanical securement and gluing.

13. The household appliance of claim 1, further comprising an additional external housing wall which flanks the at least one appliance wall, wherein the acoustic sealing frame and the covering plate are positively held in a gap space between the at least one appliance wall and the additional external housing wall.

14. The household appliance of claim 13, wherein the covering plate forms or replaces at least part of the external housing wall.

15. The household appliance of claim 1, wherein the covering plate is produced from a substantially air-borne noise damping material.

16. The household appliance of claim 15, wherein the substantially air-borne noise damping material includes fibers selected from the group consisting of cotton, kenaf, and polyester fibers, or includes at least one of embossed fleece or felt, cardboard, and plastic.

17. The household appliance of claim 1, wherein the sealing frame has a geometric shape which is closed all the way around, and is mounted on an edge zone of the at least one appliance wall.

18. The household appliance of claim 17, wherein the sealing frame has a substantially rectangular configuration.

19. The household appliance of claim 1, constructed as a dishwasher with a dishwasher interior surrounded by washing tank walls and a door, with at least one of the washing tank walls and an inner wall of the door being externally provided with the acoustic sealing frame and the covering plate.

20. The household appliance of claim 1, wherein the acoustic sealing frame is formed by a structured or panel element which has a through-opening, said covering plate closing the through-opening.

21. The household appliance of claim 20, wherein the structured or panel element is an acoustic insulation mat and optionally additionally thermal.

22. The household appliance of claim 20, wherein the structured or panel element is produced from a substantially air-borne noise absorbing material.

23. The household appliance of claim 20, wherein the structured or panel element is produced from an absorbent fleece.

24. The household appliance of claim 1, wherein the acoustic sealing frame has a through-opening and is mounted on the at least one appliance wall in such a way that the through-opening comes to rest over a three-dimensionally contoured uneven or outwardly projecting partial area of the appliance wall.

25. The household appliance of claim 1, wherein the sealing frame rests largely completely on a substantially plane partial area of the at least one appliance wall.

26. The household appliance of claim 25, wherein the substantially plane partial area is an edge zone area of the at least one appliance wall.

27. The household appliance of claim 1, wherein the covering plate is constructed so as to be substantially plane.

28. The household appliance of claim 1, wherein the covering plate has a layer thickness which is less than a layer thickness of the acoustic sealing frame.

29. The household appliance of claim 1, wherein the covering plate sits with an overlapping edge zone on an outside of the acoustic sealing frame so as to cover a through-opening of the acoustic sealing frame.

30. A household appliance, comprising:

an appliance wall delimiting a space;

an acoustic sealing frame provided along an edge zone section of the appliance wall to enclose the appliance wall and projecting outwardly with respect to an outer face of the appliance wall by a predefined transverse distance; and

a covering plate attached to an outside of the acoustic sealing frame in such a way that an outer face of the appliance wall is covered by the covering plate to provide noise insulation.

31. The household appliance of claim 30, wherein the acoustic sealing frame is made at least partially from at least one of an airborne-noise absorbing and reflecting sealing material.

32. The household appliance of claim 31, wherein the sealing material of the acoustic sealing frame includes a substantially noise-absorbing material.

33. The household appliance of claim 32, wherein the substantially noise-absorbing material is at least one of an elastically and plastically deformable material.

34. The household appliance of claim 33, wherein the deformable material is foam, absorbent fleece or felt.

35. The household appliance of claim 30, further comprising an anti-drumming layer on the outer face of the appliance wall.

36. The household appliance of claim 35, wherein the anti-drumming layer is a bitumen mat.

37. The household appliance of claim 30, wherein the covering plate and the acoustic sealing frame extend over a corner region of the space.
