Abstract

A household appliance includes a functional compartment, and an insulation arrangement provided on an outer side of the functional compartment for thermal and/or acoustic insulation of the functional compartment. The insulation arrangement includes an insulation element which is made in one piece from a plastic material selected such that a surface of the insulation element in facing relation to the functional compartment adheres to the functional compartment and is separable therefrom in a non-destructive manner. A component arranged outside the functional compartment is at least substantially encapsulated in the insulation element.

First claim

The invention claimed is:

1. A household appliance, comprising:
a functional compartment;
an insulation arrangement provided on an outer side of the functional compartment for thermal and/or acoustic insulation of the functional compartment, said insulation arrangement including a first insulation element which is made in one piece from a plastic material selected such that a surface of the first insulation element in facing relation to the functional compartment adheres to the functional compartment and is separable therefrom in a non-destructive manner; and
a component arranged outside the functional compartment and at least substantially encapsulated by the plastic material of the first insulation element foaming onto the component such that the plastic material is between the component and the functional compartment.

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

3. The household appliance of claim 1 , wherein the functional compartment, is a dishwashing compartment.

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

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

6. The household appliance of claim 1 , wherein the plastic material is a foam polyurethane.

7. The household appliance of claim 1 , wherein the component is a member selected from the group consisting of a water-conducting component, an air-conducting component, a water pocket, a plastic part for introducing a force into the dishwashing compartment, a fan, a motor, a spring, a cable, an electrical lead or component, a fleece, a mat, a plastic component, a foam, and a bitumen.

8. The household appliance of claim 1 , wherein the first insulation material is configured to completely encapsulate the component.

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 compartment and the second insulation element.

10. The household appliance of claim 9 , wherein the component is in contact with the second insulation element.

11. The household appliance of claim 9 , wherein the plastic material of the first insulation element is foamed onto the second insulation element.

12. A method for producing a household appliance, said method comprising:
producing a first insulation element of a plastic material as part of an insulation arrangement for thermal and/or acoustic insulation of a functional compartment;
encapsulating a component, arranged outside the functional compartment, by plastic material of the first insulation element foaming onto the component such that the plastic material is between the component and the functional compartment; and
attaching the insulation arrangement to the outer side of the functional compartment in such a way that a surface of the first insulation element in facing relation to the functional compartment adheres to the functional compartment and is separable therefrom in a non-destructive manner.

13. The method of claim 12 , wherein the household appliance is a household dishwasher.

14. The method of claim 12 , wherein the functional compartment is a dishwashing compartment.

15. The method of claim 12 , wherein the plastic material has an adhesive property in a cured and/or cross-linked state.

16. The method of claim 12 , wherein the component is encapsulated by placing the component into a mold, which is filled with the plastic material.

17. The method of claim 12 , further comprising arranging the first insulation element between the functional compartment and a second insulation element of the insulation arrangement.
