Abstract

An insulating structure for an appliance includes a trim breaker, a wrapper, and a liner. The wrapper and liner coupled to the trim breaker and at least partially defining a structural cabinet. A barrier is positioned between the liner and the wrapper. The barrier is also coupled to the trim breaker. An inner compressible gasket is proximate the liner, and an outer gasket is proximate the wrapper. The inner gasket and the outer compressible gasket are coupled to the barrier.

First claim

What is claimed is:

1. An insulating structure for an appliance comprising:
a trim breaker;
a wrapper coupled to the trim breaker;
a liner coupled to the trim breaker, wherein the liner and the wrapper at least partially define a structural cabinet;
a barrier having an insulation surface and an adhering surface with edge portions between the insulation surface and the adhering surface, the barrier being positioned between the liner and the wrapper and coupled to the trim breaker via the adhering surface;
an inner gasket proximate the liner and coupled to the barrier; and
an outer gasket proximate the wrapper and coupled to the barrier, the inner gasket and the outer gasket each disposed around the edge portions of the barrier and including a first lip coupled to the insulation surface and a second lip coupled to the adhering surface, wherein the trim breaker further defines an inner groove, a central groove, and an outer groove, and wherein the inner gasket is at least partially disposed within the inner groove and the outer gasket is at least partially disposed within the outer groove.

2. The insulating structure of claim 1 , wherein the barrier is a material selected from the group consisting of glass, ceramic, and glass-ceramic.

3. The insulating structure of claim 1 , wherein the barrier is coupled to the trim breaker by adhesive disposed within the central groove.

4. The insulating structure of claim 1 , including insulation materials disposed within a cavity defined by the liner and the wrapper.

5. The insulating structure of claim 1 , wherein the wrapper is positioned within the outer groove and the liner is positioned within the inner groove.

6. The insulating structure of claim 2 , wherein the barrier includes a first film and a second film.

7. The insulating structure of claim 1 , wherein the inner gasket and the outer gasket cooperate to at least partially cover the insulation surface of the barrier.

8. The insulating structure of claim 1 , wherein the barrier is a glass barrier.

9. The insulating structure of claim 5 , wherein the inner gasket and the liner engage adhesive disposed in the inner groove.

10. The insulating structure of claim 5 , wherein the outer gasket and the wrapper engage adhesive disposed in the outer groove.

11. The insulating structure of claim 1 , wherein a depth of the central groove is shallower than a depth of the inner groove and shallower than a depth of the outer groove.
