Abstract

A domestic appliance, in particular a domestic dishwasher, includes at least one component, and at least one noise-deadening and/or sound-insulating coating applied on the component. The noise-deadening and/or sound-insulating coating includes or is made entirely of a reactively cured bituminous mixture. The component can be a wall section for delimiting a rinsing chamber of the dishwasher, or can be a base tray of a rinsing container of the dishwasher.

Claims

1. A domestic appliance, comprising:

at least one component; and

at least one noise-deadening and/or sound-insulating coating applied on the component, said noise-deadening and/or sound-insulating coating including a reactively cured bituminous mixture.

2. The domestic appliance of claim 1, wherein the noise-deadening and/or sound-insulating coating is made entirely of the reactively cured bituminous mixture.

3. The domestic appliance of claim 1, embodied as a dishwasher.

4. The domestic appliance of claim 1, further comprising a rinsing chamber, said component being a wall section for delimiting the rinsing chamber.

5. The domestic appliance of claim 1, further comprising a rinsing container, said component being a base tray of the rinsing container.

6. The domestic appliance of claim 1, wherein the component is temperature-sensitive.

7. The domestic appliance of claim 1, wherein the component is made of plastic.

8. The domestic appliance of claim 7, wherein the plastic is polypropylene,

9. The domestic appliance of claim 1, further comprising a coating applied upon the component before application of the noise-deadening and/or sound-insulating coating, said coating being a member selected from the group consisting of lacquer and primer.

10. The domestic appliance of claim 1, wherein the bituminous mixture is free-flowing and curable and includes a mixture of at least one first constituent and of at least one second constituent, with the first and second constituents being configured in one of three ways, a first way in which the first constituent contains a basic bonding agent, a flux oil, and an added reactive agent that are mutually coordinated such that an activator is needed for curing, and in which the second constituent contains the activator, a second way in which the first constituent contains a basic bonding agent and a flux oil that are mutually coordinated such that an added reactive agent is needed for curing, and in which the second constituent contains the added reactive agent, a third way in which the first constituent contains a basic bonding agent and a flux oil that are mutually coordinated such that an added reactive agent and an activator are needed for curing, and in which the second constituent contains the added reactive agent and the activator.

11. A method for producing a domestic appliance, comprising applying at least one noise-deadening and/or sound-insulating coating of a reactively curing bituminous mixture to a component for noise deadening and/or sound insulating of the component.

12. The method of claim 11 for producing a domestic dishwasher.

13. The method of claim 11, wherein the respective noise-deadening and/or sound-insulating coating is sprayed onto the component.

14. The method of claim 11, wherein the bituminous mixture has at least one first constituent and at least one second constituent, with the first constituent including a liquid constituent with bitumen and oil and/or resin to which at least one solid is added, and with the second constituent including a hardener.

15. The method of claim 14, wherein the oil and/or resin is made of renewable raw material.

16. The method of claim 14, wherein the at least one solid has at least one mineral constituent.

17. The method of claim 16, wherein the at least one mineral constituent is rock meal, Solnhofen cement, or white fine lime.

18. The method of claim 14, wherein the first constituent is made entirely of the liquid constituent with bitumen and oil and/or resin to which at least one solid is added, and the second constituent is made entirely of the hardener.
