A filter for a water cooler includes a housing having a surface and a cavity with cavity ports. The filter end is adapted to be received in the housing. The filter end includes a cylindrical base having a surface and a neck extending from the surface. The neck has filter ports and a side surface. The side surface has oppositely directed axially extending elongated protrusions configured to be received in channels in the housing. The base surface includes a complex set of protrusions which are adapted to be received in a similarly configured set of recesses in the housing surface. The protrusions/recesses may take the form of letters, numbers or symbols. The filter end is be fully seated in the housing in bayonet-type fashion to connect the filter ports and the housing ports o permit water to flow through the filter from the water supply to the water cooler.

A refrigerator includes a body configured to include a storage compartment, a door portion configured to include an inner door pivotably coupled to the body to open/close the storage compartment and an outer door pivotably provided in front of the inner door, an ice making chamber formed at the door portion to be divided from the storage compartment by the inner door and to be opened or closed by the outer door, an ice making system accommodated in the ice making chamber, a dispenser provided at the door portion to provide water and ice, and a water filter mountable at the door portion to purify water supplied from an external water supply source. The ice making chamber is easily accessible by opening only the outer door while the inner door is closed and prevent cold air in the storage compartment from flowing out.

The present invention relates to new and useful improvements in the method of purifying water. The refrigerator has a storage chamber therein for a water filter device with a coconut shell activated carbon rod installed in the storage chamber to purify water supplied from an external water supply source.

A water purifying apparatus for a refrigerator includes a head, a filter housing inserted into the head, a filtering member inside the filter housing, a head insertion portion inserted into the head and coupled to the head, and a fixing portion protruding along a circumference of the head insertion portion, and a sealing member fixed to the fixing portion and disposed along a circumference of the filter housing. The sealing member includes a sealing portion configured to protrude outward along the circumference of the filter housing so as to be in close contact with the inner surface of the head, a hook portion disposed below the fixing portion to be restricted by the fixing portion, and a connection portion configured to connect the sealing portion to the hook portion.

The filter end is be fully seated in the housing in bayonet-type fashion to connect the filter ports and the housing ports o permit water to flow through the filter from the water supply to the water cooler.

A refrigerator includes a refrigerator compartment having a rear wall with an inwardly angled portion. A first and second shelf assemblies are disposed within the refrigerator compartment. The first shelf assembly includes a panel supported on a frame assembly to define a cavity positioned below a portion of the panel. The second shelf assembly includes front and top panels that cooperate with a surface of the inwardly angled portion of the rear wall to define a storage cavity therebetween. A water filtration system includes a water filter assembly laterally disposed within the storage cavity of the second shelf assembly. A water dispenser system includes a dispenser paddle operably coupled to the first shelf assembly and interconnected to the water filter assembly by a water supply line that is concealed within the cavity of the first shelf assembly by the opaque portion of the panel of the first shelf assembly.

A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A refrigerator utilizes a quick fill dispenser that incorporates a fluid storage receptacle that is easily removable for cleaning and/or dispensing independently of the refrigerator.

A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

Disclosed herein is a refrigerator, and more particularly, to a refrigerator including a water supply system. The refrigerator includes a main body including a storage compartment, and a water supply assembly disposed in the storage compartment. The water supply assembly includes a first filter mounting portion provided to allow a first filter to be mounted thereon, and a second filter mounting portion provided to allow a second filter to be mounted thereon, and including a residual water guide configured to guide residual water in the second filter mounting portion to the first filter mounting portion.
