  • Publication number: 20240051268
    Abstract: A vacuum insulated structure includes a trim breaker having a wrapper channel and a liner channel that extend perimetrically about the trim breaker. An inner liner is attached to the trim breaker at the liner channel. An outer wrapper is attached to the trim breaker at the wrapper channel. A metallic plate is disposed within the trim breaker and extends from a first area proximate the liner channel to a second area proximate the wrapper channel. The metallic plate defines an internal barrier to gas permeation through the trim breaker.

  • Patent number: 11808514
    Abstract: A refrigerator includes a vacuum-insulated cabinet structure enclosing an insulating cavity and including an outer wrapper having a first side wall defining a perimeter, an outer frame portion defined radially inward of the perimeter, and an inner area surrounded and supported by the outer frame portion. The inner area initially defines a first planar level with at least a portion of the outer frame portion extending to a second planar level parallel to and spaced apart from the first planar level in an axially outward direction. The insulating cavity is sealed and has a vacuum drawn therefrom with the outer frame portion deformed such that the inner area is moved axially inward away from the second planar level under a force of the vacuum within the insulating cavity with at least the portion of the outer frame portion remaining at the second planar level.

  • Patent number: 11732954
    Abstract: A refrigerating appliance includes a cabinet assembly that defines an access opening for storing food goods. The cabinet assembly defines an insulating cavity that receives insulation. A mullion assembly extends across the access opening and a trim breaker extends about the access opening. The trim breaker includes a body portion that covers the insulating cavity. First and second connecting flanges extend outwardly from the body portion in a first direction and operably coupled to an inside wall and an outside wall of the cabinet assembly, such that the trim breaker seals the insulating cavity. A forward spacing flange extends outwardly from the body portion of the trim breaker in a second direction that is opposed to the first direction of the first and second connecting flanges. The forward spacing flange contacts the mullion assembly and at least partially defines a receiving space between the mullion assembly and the trim breaker.
