B01D 35/30
B01D 29/96

Abstract:

A filter housing assembly for fluid filtration which may be attached to, and removed from, a filter base by a push-actuated release. The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.

Abstract:

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.

International Classification:

B01D 35/30
B01D 35/143
B01D 29/96

Abstract:

A filter base for receiving a complementary mating filter housing assembly. The filter base includes 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 filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions 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.

G06F 21/44

Abstract:

An authentication system for authenticating a water filter cartridge at an appliance is provided. The water filter cartridge comprises a connection assembly having one or more connection devices that are structured for engaging an electrical connector of an appliance water filter manifold assembly of an appliance, to establish an electrical connection between the connection assembly and a controller of the appliance. A method of use of the water filter cartridge at the appliance comprises inserting the water filter cartridge into a receptacle of an appliance water filter manifold assembly. A method of authentication of the water filter cartridge comprises establishing an electrical communication link between a memory device of a water filter cartridge and an appliance water filter manifold assembly of the appliance, and retrieving, via the electrical communication link, a unique identifier associated with the water filter cartridge from the memory device.
