Abstract
A vacuum insulated appliance includes a cabinet with an outer wrapper and an inner liner coupled to the outer wrapper. A vacuum insulated cavity is defined between the outer wrapper and the inner liner. A trim breaker is coupled to the outer wrapper and the inner liner and seals the vacuum insulated cavity. An evacuation port is defined by the outer wrapper. An insulation powder is disposed in the vacuum insulated cavity. An open-cell foam is coupled to at least one of an inner surface of the outer wrapper and an inner surface of the inner liner. The open-cell foam defines a first plurality of pores that define a first plurality of airflow paths in fluid communication with the vacuum insulated cavity and the evacuation port for evacuating air from the vacuum insulated cavity, through the first plurality of airflow paths, and through the evacuation port.
