Abstract

A household appliance includes a functional container, an insulation arrangement provided on an outside of the functional container and configured to thermally and/or acoustically insulate the functional container. The insulation arrangement includes a single-piece first insulation element which is made of a plastic material selected such that a surface of the first insulation element in facing relation to the functional container adheres to the functional container and is separable herefrom in a non-destructive manner.

First claim

The invention claimed is:

1. A household appliance, comprising:
a functional container;
an insulation arrangement provided on an outside of the functional container and configured to thermally or acoustically insulate the functional container, said insulation arrangement including a first insulation element consisting of a single plastic material that has an adhesive property and that exhibits a specific heat conductivity of lower than 0.1 W/(mK), the single plastic material being selected such that a surface of the first insulation element in facing relation to the functional container directly adheres to the functional container and is separable herefrom in a non-destructive manner, wherein the single plastic material is configured to be formed by mixing a plurality of chemical components; and
a fastening facility configured to press the insulation arrangement against the functional container to maintain a contact pressure of the insulation arrangement against the functional container throughout a service life of the household appliance.

2. The household appliance of claim 1 , wherein the household appliance is constructed in a form of a household dishwasher.

3. The household appliance of claim 1 , wherein the functional container is a dishwasher cavity.

4. The household appliance of claim 1 , wherein the single plastic material has the adhesive property in a cured and/or cross-linked state.

5. The household appliance of claim 1 , wherein the single plastic material is polyurethane.

6. The household appliance of claim 1 , wherein the single plastic material is an expanded polyurethane.

7. The household appliance of claim 1 , wherein the single plastic material has a viscoelastic property.

8. The household appliance of claim 1 , wherein the fastening facility is connected to the functional container.

9. The household appliance of claim 1 , wherein the insulation arrangement includes a second insulation element, said first insulation element being arranged between the functional container and the second insulation element.

10. The household appliance of claim 9 , wherein the fastening facility is configured as an external cladding on the outside of the functional container, said second insulation element being arranged between the fastening facility and the first insulation element.

11. The household appliance of claim 9 , wherein the fastening facility is configured as a grid or mesh on the outside of the functional container, said second insulation element being arranged between the fastening facility and the first insulation element.

12. The household appliance of claim 9 , wherein the second insulation element has a reinforcement.

13. The household appliance of claim 12 , wherein the reinforcement is configured in a form of ribs or beads.

14. The household appliance of claim 12 , wherein the reinforcement is configured to project away from the functional container out of the second insulation element.

15. The household appliance of claim 12 , wherein the reinforcement is configured to project toward the functional container into the second insulation element.

16. The household appliance of claim 1 , wherein the first insulation element is configured to exhibit a specific heat conductivity of lower than 0.05 W/(mK).

17. The household appliance of claim 1 , wherein the first insulation element is configured to exhibit a specific thermal capacitance of lower than 2,000 J/(kgK).

18. The household appliance of claim 1 , wherein the first insulation element is configured to exhibit a loss factor of greater than 0.2, and wherein the loss factor represents a ratio of a loss-afflicted imaginary part of a complex variable in relation to a loss-free real part of the complex variable.

19. The household appliance of claim 1 , wherein the adhesive property of the single plastic material is further based on physical-mechanical forces.
