Abstract

A vacuum insulated structure includes a first panel having an inner surface defining an area. The first panel includes a vacuum port. A trim breaker interconnects the first panel with a second panel in an air-tight manner to define a vacuum cavity therebetween. A first filter member is disposed on and substantially covers the area of the inner surface of the first panel and the vacuum port of the first panel. A second filter member substantially covers the first filter member to define a channel therebetween. The channel includes an area commensurate with the area of the inner surface of the first panel. The first panel may also include a mesh member covered by a filter member to define a channel therebetween to improve evacuation time using the channel to evacuate the vacuum cavity.

First claim

What is claimed is:

1. A vacuum insulated structure, comprising:
a first panel having an inner surface, wherein the first panel includes a vacuum port;
a second panel;
a trim breaker interconnecting the first and second panels in an air-tight manner to define a vacuum cavity therebetween;
a first filter member disposed on and substantially covering the inner surface of the first panel and the vacuum port; and
a second filter member substantially covering the first filter member to define a channel therebetween, wherein the channel includes an area commensurate with the inner surface of the first panel.

2. The vacuum insulated structure of claim 1 , wherein the vacuum port is fluidically coupled to the channel.

3. The vacuum insulated structure of claim 2 , wherein the first and second filter members are comprised of a filter paper material.

4. The vacuum insulated structure of claim 1 , including:
an adhesive member interconnecting the second filter member and the inner surface of the first panel.

5. The vacuum insulated structure of claim 4 , wherein the adhesive member includes a frame assembly that surrounds an outer perimeter edge of the second filter member, such that a first portion of the frame assembly of the adhesive member is coupled to the inner surface of the panel and a second portion of the frame assembly of the adhesive member is coupled to the outer perimeter edge of the second filter member.

6. The vacuum insulated structure of claim 1 , wherein the first and second panels are formed from a metal material.

7. The vacuum insulated structure of claim 1 , including:
an insulation material disposed in the vacuum cavity between the first and second panels.
