Abstract: A water filtering system for a refrigerator includes a mounting head preferably arranged under a temperature control housing in a fresh food compartment. A replaceable filter cartridge is adapted to be selectively attached to the mounting head in order to complete a fluid circuit from a water supply source to at least one of a water dispenser and an ice maker. The filter cartridge and the mounting head have cooperating camming structure which axially draws a stem portion of the cartridge into a port of the mounting head upon rotation of the cartridge relative to the mounting head during installation of the cartridge. Furthermore, camming structure is also provided to at least partially, axially withdraw the stem portion from the port upon rotation of the cartridge a predetermined amount in an opposing direction. Also provided as part of the water filtering system is a plug which can be used to complete the fluid circuit in the absence of a filter cartridge.

Abstract: A water tank having a body portion that slopes away, in multiple directions, from an outlet thereof is adapted to be mounted within a refrigerator cabinet in a substantially horizontal plane. The water tank is preferably integrally molded with multiple, parallel-arranged flow paths and with a plurality of upstanding tabs for use in mounting the water tank horizontally in a fresh food compartment of a refrigerator cabinet. The inlet and outlet areas of the tank are designed to minimize the potential for trapping air within the tank. In addition, the tank is formed with integrally molded clips for use in attaching a water tube to the tank. When used in a top mount refrigerator, the tank is particularly adapted to be mounted at a rear underside portion of a fresh food liner that forms part of a mullion divider assembly so as to be generally out of visual sight of the consumer, while being in direct heat exchange relationship with cooling air within the compartment.
