Abstract

A dishwashing machine, in particular a household dishwashing machine, includes a box-shaped washing tank for receiving items to be washed, and a base carrier for support of the washing tank. The base carrier has a technology space for accommodating electrical components of the dishwashing machine. The technology space is arranged between a floor formed on the base carrier and the washing tank and is at least partially surrounded by a sound proofing element designed as a three-dimensional formed component.

Claims

1. A dishwashing machine, comprising:

a box-shaped washing tank for receiving items to be washed;

a base carrier supporting the washing tank;

said base carrier at least partially surrounding a perimeter of a technology space when viewed from above the dishwashing machine, the technology space accommodating electrical components of the dishwashing machine, said technology space being arranged between a floor formed on the base carrier and an undersurface of the washing tank; and

a soundproofing element designed as a three-dimensional molded component and at least partially surrounding the technology space along a portion of at least two sides of the perimeter of the technology space.

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

3. The dishwashing machine of claim 1, wherein the soundproofing element includes a front wall, which rests against a front region of the base carrier and against a front region of the washing tank.

4. The dishwashing machine of claim 1, wherein the soundproofing element includes a front wall, which seals a front opening placed between the floor and the washing tank.

5. The dishwashing machine of claim 1, wherein the soundproofing element comprises side walls which face one another, each of the side walls on opposite sides of the perimeter of the technology space and resting against a lateral region of the base carrier and against a lateral region of the washing tank.

6. The dishwashing machine of claim 1, wherein the soundproofing element comprises side walls which face one another, said side walls being on opposite sides of the perimeter of the technology space and sealing a lateral opening placed between the floor and the washing tank.

7. The dishwashing machine of claim 1, wherein the soundproofing element comprises a base section which is arranged on an upper side of the floor of the base carrier and within the perimeter of the technology space.

8. The dishwashing machine of claim 1, wherein the soundproofing element includes a rear wall which rests against a rear region of the base carrier and a rear region of the washing tank.

9. The dishwashing machine of claim 1, wherein the soundproofing element includes a rear wall which seals a rear opening between the floor and the washing tank.

10. The dishwashing machine of claim 1, wherein the soundproofing element is essentially manufactured from a carrier material and from a filler material incorporated therein.

11. The dishwashing machine of claim 10, wherein the carrier material is phenol resin.

12. The dishwashing machine of claim 10, wherein the filler material includes at least one of cotton fibers and polyester fibers.

13. The dishwashing machine of claim 1, wherein the soundproofing element is removably held in its intended position.

14. The dishwashing machine of claim 1, wherein the soundproofing element is embodied and arranged so as to be removable from its intended position when the washing tank is placed on the base carrier.

15. The dishwashing machine of claim 1, wherein the soundproofing element comprises:

a front wall extending along at least a portion of a front of the perimeter of the technology space; and

a sidewall extending from the front wall in a direction substantially transverse to the front wall, the sidewall extending along at least a portion of a side of the perimeter of the technology space.

16. The dishwashing machine of claim 15, wherein the soundproofing element comprises:

a second sidewall extending from the front wall in the direction substantially transverse to the front wall, the second sidewall being on an opposite side of the technology space from the sidewall and extending along at least a portion of a second side of the perimeter of the technology space.

17. The dishwashing machine of claim 15, wherein the soundproofing element comprises:

a rear wall extending along at least a portion of a rear of the perimeter of the technology space, the rear wall being on an opposite side of the technology space from the front wall.

18. The dishwashing machine of claim 15, wherein the soundproofing element comprises:

a base section extending along at least a portion of the floor formed on the base carrier and within the perimeter of the technology space.

19. The dishwashing machine of claim 18, wherein the soundproofing element comprises:

a rear wall extending along at least a portion of a rear of the perimeter of the technology space, the rear wall being on an opposite side of the technology space from the front wall.

20. The dishwashing machine of claim 1, wherein the soundproofing element has an exterior contour following an interior contour of the base carrier along the portion of the at least two sides of the perimeter of the technology space, and an upper edge following a contour of the undersurface of the washing tank.

21. The dishwashing machine of claim 1, wherein the base carrier includes a support element at a front corner of a front of the perimeter of the technology space;

and

wherein the soundproofing element includes;

a front wall extending along at least a portion of the front of the perimeter of the technology space; and

a flange section extending from the front wall in a direction substantially transverse to the front wall along an internal side of the support element of the base carrier.

22. The dishwashing machine of claim 21, wherein the flange section further includes a portion extending in a direction substantially parallel to the front wall and along a second internal side of the support element.

23. The dishwashing machine of claim 1, wherein the soundproofing element has a first section having a first material thickness and a second section having a second material thickness, wherein the first material thickness is different than the second material thickness.

24. The dishwashing machine of claim 15, wherein the front wall has a first material thickness extending in a direction substantially transverse to the front of the perimeter of the technology space,

wherein the sidewall has a second material thickness extending in a direction substantially transverse to the side of the perimeter of the technology space;

and

wherein the first material thickness is greater than the second material thickness.
