Abstract

An acoustic blanket is provided for an appliance. The acoustic blanket includes a main body, a margin and a fold line connecting the main body to the margin. The margin is folded about the fold line relative to the main body in order to provide an edge seal around the edge of the appliance.

Claims

1. An acoustic blanket for an appliance, comprising:

a main body;

a margin; and

a fold line connecting said main body to said margin.

2. The acoustic blanket of claim 1, wherein said margin has a width of between about 5 and about 7 cm.

3. The acoustic blanket of claim 1, wherein said margin has a width of about 6.3 cm.

4. The acoustic blanket of claim 1, wherein said acoustic blanket is constructed from thermoplastic material.

5. The acoustic blanket of claim 1, wherein said main body and margin are integrally formed from a material selected from a group consisting of polyester, polyolefin, polyethylene, rayon, nylon, acrylic, hemp, kenaf, cotton, fiberglass and combinations thereof.

6. The acoustic blanket of claim 1, wherein said fold line is scored.

7. The acoustic blanket of claim 1, wherein said fold line is perforated.

8. The acoustic blanket of claim 1, wherein said main body is substantially T-shaped.

9. A dishwasher, comprising:

a housing including a washing chamber and a door for gaining access to said washing chamber;

a washing nozzle in said washing chamber for directing a fluid stream against dishes held in said washing chamber;

a circulation pump for circulating fluid under pressure through said washing nozzle; and

an acoustical insulation blanket extending around said washing chamber said acoustical insulation blanket including a main body, a margin and a fold line connecting said main body to said margin.

10. The dishwasher of claim 9, wherein said margin is folded relative to said main body about said fold line to form an edge seal around an edge of said housing.

11. The dishwasher of claim 10, wherein said margin has a width of between about 5 and about 7 cm.

12. The dishwasher of claim 10, wherein said margin has a width of about 6.3 cm.

13. The dishwasher of claim 9, wherein said acoustic insulation blanket is constructed from thermoplastic material.

15. The dishwasher of claim 9, wherein said fold line is scored.

16. The dishwasher of claim 9, wherein said fold line is perforated.

17. A method of forming an edge seal around an edge of an appliance housing with an acoustic blanket, comprising:

providing an acoustic blanket with a main body and a margin connected together by a fold line; and

folding said acoustic blanket about said fold line so as to extend said acoustic blanket around said edge of said housing and form an integral edge seal.

18. The method of claim 17 including securing said margin around said edge by a procedure selected from a group consisting of impulse heat sealing, sonic welding, mechanical fastening and combinations thereof.
