Problems solved by technology

For example, edge effects can decrease a thermal efficiency of the vacuum insulation panel.
In addition, a shape of the vacuum insulation panel can transfer or be impressed on the outer panel such that a cosmetic appearance of the outer panel is negatively affected.
In particular, the outer panel can appear unsmooth.
Further, suitable adhesion between the vacuum insulation panel and the outer panel can be difficult if a surface finish of the vacuum insulation panel is not sufficiently smooth and includes irregularities.
Thus, a cost of the vacuum insulation panel may be increased due to the tolerances required to properly adhere the vacuum insulation panel directly to the metal outer panel.
In particular, expensive bonding methods and / or adhesives may be required to properly attach the vacuum insulation panel directly to the metal outer panel.

Abstract

A door for an appliance is provided. The door of the appliance includes an outer panel with a rear surface. The door also includes a vacuum insulation panel and a barrier layer. The barrier layer is positioned between the rear surface of the outer panel and the vacuum insulation panel within the door.

Description

FIELD OF THE INVENTION[0001]The present subject matter relates generally to appliances, such as refrigerator appliances, and doors for the same.BACKGROUND OF THE INVENTION[0002]Vacuum insulation panels generally include a nearly gas-tight enclosure surrounding a rigid core, from which atmospheric gases have been at least partially evacuated. Certain refrigerator appliances include vacuum insulation panels for thermally insulating a cabinet and / or doors of the refrigerator appliances. The vacuum insulation panels can decrease heat leakage into chilled chambers of the refrigerator appliances and thereby increase an efficiency of the refrigerator appliance. To further increase the efficiency of the refrigerator appliance, the vacuum insulation panels can be utilized in combination with conventional foam or fiberglass insulation within the cabinet and doors of the refrigerator appliances. In certain refrigerator appliances, the vacuum insulation panels are attached or mounted directly t...
