Abstract
A refrigerator door includes an outer metal shell having an outer rectangular panel connected to four inwardly turned side panels connected to an inwardly facing peripheral flange. An inner liner has a peripheral flange in registry with the outer door shell flange, a central wall and a pair of vertical, inwardly projecting sidewalls connecting the central wall to the liner flange. Each sidewall includes a scallop in the form of an inwardly opening notch at a select aligned longitudinal position of the inner liner. The central wall includes a transverse inwardly opening recess groove extending between the sidewalls at the select longitudinal position to provide an expansion joint to prevent bowing when an insulation cures in the space between the liner and the shell and when the refrigerator is in operation, thus cooling the door. Moreover, C-shaped beams in the door aid in providing strength to further prevent bowing.
