Abstract

A dishwasher includes a tub with a sidewall. A vent is attached to the sidewall of the tub. An inlet line is disposed outside the sidewall and is attached to the vent. The inlet line provides water to the tub through the sidewall. An insulation blanket is disposed over the tub sidewall and the vent. A water vapor path extends from the vent to at least an edge of the insulation blanket.

Claims

1. A dishwasher, comprising:

a tub having a sidewall;

a vent attached to the sidewall;

an inlet line disposed outside the sidewall and attached to the vent for providing water to the tub through the sidewall;

an insulation blanket disposed over an outer surface of the tub sidewall and the vent; and

a water vapor path formed by a cut through a side of the insulation blanket that extends a length upward at an angle from the vent to at least an edge of the insulation blanket, wherein the water vapor path is a space between a vapor barrier on a side of the insulation blanket that faces toward the tub and the sidewall of the tub that faces toward the insulation blanket.

2. The dishwasher of claim 1, wherein the vent is an anti-backflow device.

3. The dishwasher of claim 1, wherein the insulation blanket comprises a facing.

4. The dishwasher of claim 3, wherein the facing is on a side of the insulation blanket that faces away from the tub.

5. The dishwasher of claim 3, wherein the facing is on a side of the insulation blanket that faces toward the tub.

6. The dishwasher of claim 1, wherein the vapor barrier is also provided on a side of the insulation blanket that faces away from the tub.

7. The dishwasher of claim 1, wherein the vapor barrier comprises a sleeve that wraps around the insulation blanket.

8. A dishwasher installation, comprising:

cabinets;

a countertop disposed on the cabinets;

wherein the cabinets and the countertop are arranged to form a dishwasher cavity;

a dishwasher disposed in the cavity, the dishwasher comprising;

a tub having a sidewall;

a vent attached to the sidewall;

an inlet line disposed outside the sidewall and attached to the vent for providing water to the tub through the sidewall;

an insulation blanket disposed over an outer surface of the tub sidewall and the vent; and

a water vapor path formed by a cut through a side of the insulation blanket that extends a length upward at an angle from the vent to at least an edge of the insulation blanket wherein the water vapor path, wherein the water vapor path is a space between a vapor barrier on a side of the insulation blanket that faces toward the tub and the sidewall of the tub that faces toward the insulation blanket.

9. The dishwasher installation of claim 8, wherein the vent is an anti-backflow device.

10. The dishwasher installation of claim 8, wherein the insulation blanket comprises a facing.

11. The dishwasher installation of claim 10, wherein the facing is on a side of the insulation blanket that faces away from the tub.

12. The dishwasher installation of claim 10, wherein the facing is on a side of the insulation blanket that faces toward the tub.

13. The dishwasher installation of claim 8, wherein the water vapor path is a space between a vapor barrier on a side of the insulation blanket that faces toward the tub and the sidewall of the tub that faces toward the insulation blanket.

14. The dishwasher installation of claim 13, wherein the vapor barrier is also provided on a side of the insulation blanket that faces away from the tub.

15. The dishwasher installation of claim 13, wherein the vapor barrier comprises a sleeve that wraps around the insulation blanket.

16. A dishwasher, comprising:

a tub having a sidewall;

a vent attached to the sidewall;

an inlet line disposed outside the sidewall and attached to the vent for providing water to the tub through the sidewall;

an insulation blanket having a width disposed over an outer surface of the tub sidewall and the vent;

a water vapor path formed by a cut through the side of the insulation blanket that extends a length from the vent to at least an edge of the insulation blanket; and

a vapor barrier disposed over said water vapor path, wherein the water vapor path is a space between the vapor barrier on a side of the insulation blanket that faces toward the tub and the sidewall of the tub that faces toward the insulation blanket.
