A vacuum insulated cabinet structure includes first and second cover members having pre-deformed portions and perimeter portions. The perimeter portions of the first and second cover members are disposed along first and second planar levels and the pre-deformed portions of the first and second cover members include portions thereof extending outwardly relative to the first and second planar levels. A thermal bridge interconnects the first cover member and the second cover member at the perimeter portions thereof to define an insulating cavity therebetween. The insulating cavity is a sealed cavity having a vacuum drawn therefrom. The pre-deformed portions of the first and second cover members move inwardly towards the first and second planar levels under a force of the vacuum within the insulating cavity.

A vacuum insulated structure includes a first panel and a second panel, wherein the second panel is operably coupled to the first panel to define an insulating space therebetween. An airway system is disposed within the insulating space and includes portions of porous tubing configured to draw air along lengths of the porous tubing from the insulating space during an evacuation procedure. A plurality of connectors interconnect the portions of porous tubing of the airway system to inner walls of the insulating space. The connectors may include support members that extend between the panels within the insulating space to support the vacuum insulated structure under vacuum pressure. Further, first and second panels can include rigidifying structural configurations to combat vacuum bowing during the evacuation procedure.

A vacuum insulated cabinet structure includes panels having sheet metal outer side walls and polymer inner side walls. The polymer inner side walls are heat-sealed to a layer of polymer material laminated to a flat sheet metal blank to form vacuum cavities. The blank is then bent along fold lines to form a cabinet structure.

The present disclosure provides vacuum insulated articles having twoor moreinsulated volumes at reduced pressure. An article may include a first vent communicating with a first insulating space, a second vent communicating with a second insulating space, a first circular insulation seal sealing the first insulating space at the first vent; and a second circular insulation seal sealing the second insulating space at the second vent.

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.

A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel involves: a stacking step in which a first metal plate is stacked on one side of an insulating core material, and in which a backing member having an opening and a second metal plate having an evacuation port are stacked, with the opening and the evacuation port stacking, on the other surface of the core member in the order of backing member and second metal plate from the core member side; a first welding step for welding outwards of where the core member is arranged in the first metal plate and the second metal plate; an evacuating step from the evacuation port to create a vacuum in an inner area which is held between the first metal plate and the second metal plate and in which the core member is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the evacuating step, the evacuation port is sealed by means of a sealing material and the sealing material, the second metal plate and the backing member are laser welded.
