Publication number: 20180292124Abstract: A vacuum insulated structure includes a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers or elastomeric or hybrid material systems. The multi-layer sheet of material is thermoformed or vacuum formed to form a non-planar first component having a central portion and four sidewalls extending transversely from the central portion. A second component having a central portion and four sidewalls extending transversely from the central portion is secured to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space by removing gasses and moisture (water vapor). The first and second components are sealed together to form a vacuum insulated structure.Type: ApplicationFiled: June 8, 2018Publication date: October 11, 2018Applicant: WHIRLPOOL CORPORATIONInventors: Hua Liu, Laksha J. Deka, Mohamed Alshourbagy, Diptesh Mukherjee

Publication number: 20170159997Abstract: An insulation delivery apparatus for forming an insulated appliance structure includes an insulated structure having a wrapper and a liner that define an interior cavity and a hopper having a storage bin and a delivery mechanism. The delivery mechanism delivers an insulating medium from the storage bin, through an insulation conduit and into the interior cavity. The delivery mechanism operates between idle and delivery states. A pressing mechanism is coupled with the insulation conduit and is in selective engagement with the insulated structure. The pressing mechanism operates between rest and compressing states. An inner support is in selective engagement with an outer surface of the inner liner and an operable outer support in selective engagement with the outer wrapper. The inner support and the operable outer support provide structural support to the insulated structure when the pressing mechanism is in the compressing state.Type: ApplicationFiled: December 8, 2015Publication date: June 8, 2017Applicant: Whirlpool CorporationInventors: Berhanu Allo, Mohamed Alshourbagy, Jon M.
