Abstract

An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.
