An improved refrigerator of the forced refrigerated air type is disclosed in which a divider shelf is provided for the convenience of the user who wishes to convert a portion of the freezer section into a standard refrigeration section or a portion of the standard refrigerator section into a freezer section. The shelf is formed of an insulating material and is dimensioned and shaped to be positioned in a selected compartment in any of a plurality of selectable locations. The shelf has a resilient sealing member along peripheral portions which engage the corresponding walls of the compartment in which it is positioned so as to permit the shelf to selectively alter the flow of refrigerated air in such a manner as to permit the separate thermostatic temperature control of the separate sections created by the shelf. Depending upon the desired application, the shelf may or may not include a thermostatically controlled aperture to further selectively control the flow of frigid air thereby also controlling the temperature of the section thus created. Various constructions of the shelf permit the consumer to conveniently and quickly convert the refrigerator from a standard arrangement to a plurality of selectable and temperature controllable arrangements including an energy saving arrangement in which a part of the standard refrigerator section or freezer section may be totally inactivated.
In a side-by-side combination freezer and refrigerator apparatus which utilizes circulating refrigerated air to cool and thermostatically control the temperature of at least a freezer compartment and refrigerator compartment separated by an insulated wall, the improvement in combination therewith which comprises at least one divider shelf formed at least in part of at least one insulating material and dimensioned and configured to be positioned at any of a plurality of selectable locations within at least one of said freezer and refrigerator compartments, said shelf having resilient sealing means positioned along all peripheral portions thereof to engage corresponding wall portions defining said compartment in sealed relation therewith sufficient to prevent the flow of air thereby when positiond in one of said selectable locations such that when said shelf is positioned in one of said selectable locations, said shelf divides said at least one compartment into at least two sections and alters the flow of refrigerated air such that one section of said at least one compartment is not subject to the cooling effects of the refrigerated air and thereby inactivated and means to facilitate recirculation of the flow of refrigerated air through said insulated wall as altered by said shelf.
