Water dispenser and filter cartridge for use therein
A water dispenser including a water inlet adapted to receive water from a water supply, a water filter operative to filter water received from the water supply via the water inlet, a water outlet operative to provide filtered water received from the water filter, a water spill collector and a pivotably mounted drainage-equipped water container support having a first operative orientation underlying the water outlet and defining a downwardly inclined water spill drainage pathway communicating with the water spill collector and a second, non-operative, orientation not underlying the water outlet.
1. A user-replaceable filter cartridge for use in a water dispenser, said filter cartridge comprising:
a housing defining a housing top portion and a bicameral main housing portion supported by and depending from said housing top portion,
said housing top portion including a manifold defining planar element defining a water inlet manifold and a water outlet manifold communicating respectively with a water inlet connector and a water outlet connector, said water inlet connector and said water outlet connector depending from said water inlet manifold and said water outlet manifold respectively;
said bicameral main housing portion also defining at least first and second filter element housing portions housing at least first and second filter elements, each of said at least first and second filter element housing portions communicating with said water inlet manifold and with said water outlet manifold.
2. A user-replaceable filter cartridge according to claim 1 and wherein said bicameral main housing portion includes a pair of filter element containing chambers, each of which is formed with a generally cylindrical spring seat defining socket at a bottom surface thereof said pair of filter element containing chambers being integrally joined by a planar structural portion and by a planar base element which lies in a plane generally perpendicular to the plane of planar structural portion, said planar base element being formed with inlet and outlet port receiving apertures in which are located respective inlet and outlet port defining connector assemblies.
3. A user-replaceable filter cartridge according to claim 2 and wherein said inlet and outlet port defining connector assemblies each define a generally cylindrical water flow conduit on an outer surface of which are provided a pair of sealing rings.
4. A user-replaceable filter cartridge according to claim 3 and wherein disposed within each of said filter element containing chambers there is provided an elastomeric sealing pad, which supports one of said filter elements.
5. A user-replaceable filter cartridge according to claim 3 and wherein each of said filter elements is formed to have a central bore and wherein disposed over each said filter element is a top pad having a centrally disposed filtered water outlet aperture, communicating with said central bore.
6. A user-replaceable filter cartridge according to claim 5 and also comprising a manifold defining planar element sealed to said planar base element, said manifold defining planar element including respective water inlet and water outlet port communication apertures to which are sealingly joined said inlet and outlet port defining connector assemblies.
7. A user-replaceable filter cartridge according to claim 6 and wherein said manifold defining planar element is sealed to said housing top portion and defines therewith a water inlet pathway from said water inlet port communication aperture to outer peripheries of both of said filter elements.
8. A user-replaceable filter cartridge according to claim 6 and wherein said manifold defining planar element is sealed to said housing top portion and defines a water outlet pathway from a pair of filtered water apertures, which communicate with filtered water outlet apertures in said lop pads, to said outlet port defining connector assembly.
9. A user-replaceable filter cartridge according to claim 1 and wherein said filter cartridge is configured to define a locking surface.
10. A user-replaceable filter cartridge according to claim 1 and wherein said filter cartridge is configured to define a machine-readable label, which enables the filter cartridge to be automatically identified by a water dispenser.
