An appliance cabinet includes a structural envelope having an exterior surface and an interior surface that defines an insulating cavity, wherein the insulating cavity defines an at least partial vacuum. A plurality of silica-based agglomerates are disposed within the insulating cavity, wherein each agglomerate of the plurality of silica-based agglomerates includes silica-based powder insulation material that is water-densified and is at least substantially free of a material binder. A secondary insulation material is disposed within interstitial spaces defined between the plurality of silica-based agglomerates, wherein the plurality of silica-based agglomerates defines an interior structure that resists inward compressive forces exerted as a result of the at least partial vacuum defined within the insulating cavity.

A method for forming a super-insulating material for a vacuum insulated structure for an appliance includes disposing hollow glass spheres within a rotating drum, wherein a plurality of interstitial spaces are defined between the hollow glass spheres. An anchor material is disposed within the rotating drum. The hollow glass spheres and the anchor material are rotated within the rotating drum, wherein the anchor material is mixed with the hollow glass spheres to partially occupy the interstitial spaces. A silica-based material is disposed within the rotating drum. The silica-based material is mixed with the anchor material and the hollow glass spheres to define a super-insulating material, wherein the silica-based material attaches to the anchor material and is entrapped within the interstitial spaces. The silica-based material and the anchor material occupy substantially all of an interstitial volume defined by the interstitial spaces.

A method of fabricating a vacuum insulated refrigerator structure includes positioning a first barrier film in a female mold cavity. Porous filler material is positioned on the barrier film, and a second barrier film is positioned over the porous filler material. A male mold is brought into contact with the second barrier film to deform and compress the porous filler material into a 3D shape. A vacuum is formed between the first and second barrier films, and the first and second peripheral edge portions are sealed together to form a vacuum insulated core. The vacuum insulated core may be positioned between a liner and a wrapper to form an insulated refrigerator cabinet, door, or other vacuum insulated component.

A connector assembly includes a base plate that defines a fill opening and an aperture. A fill tube is coupled to a first side of the base plate. The fill tube is aligned with the fill opening. A radial flange is coupled to a second side of the base plate. The radial flange extends around the fill opening. A toggle magnet is coupled to the first side of the base plate proximate to the aperture. The toggle magnet is operable between an activated state and a deactivated state.

A refrigerated merchandising cabinet comprises an insulated casing, an interior of which forms a product display chamber. Refrigeration apparatus for generating and delivering a cold airstream through the product display chamber to cool the product display chamber is mounted on top of the casing. Access doors are mounted at a front of the casing to provide access to the product display chamber. Each access door is mounted on the casing by means of an inner frame forming an integral part of the casing and defining an access opening at the front of the casing and a complementary outer frame which is demountably engaged with the inner frame. Each door is hingedly mounted on the outer frame.

An insulating core material for a refrigerating appliance includes a plurality of insulating glass spheres, wherein a plurality of interstitial spaces are defined between at least a portion of the insulating glass spheres of the plurality of glass spheres. A coating material is applied at least to the outer surface of the insulating glass spheres, wherein the coating material modifies the outer surface to define a retaining outer surface of each insulating glass sphere of the plurality of glass spheres. A secondary insulating material is combined with the plurality of insulating glass spheres, wherein the secondary insulating material is at least partially retained by the retaining outer surfaces of the insulating glass spheres to occupy the plurality of interstitial spaces.
