Publication number: 20170160001Abstract: An insulation structure for an appliance includes a cabinet having an outer wrapper and an inner liner, with an insulating cavity defined therebetween. Insulating powder material is disposed substantially throughout the insulating cavity. An insulating gas is disposed within the insulating cavity, wherein the insulating powder material is combined with the insulating gas and cooperatively defines a suspended state and a precipitated state. The suspended state is defined by the insulating gas in motion and the insulating powder being in an aeolian suspension within the insulating gas while in motion. The precipitated state is defined by the insulating gas being in a deposition state and the insulating powder being precipitated from the insulating gas and deposited within the insulating cavity.Type: ApplicationFiled: December 8, 2015Publication date: June 8, 2017Applicant: Whirlpool CorporationInventors: Lakshya J.
