The present invention relates to a faucet assembly and, more particularly, to a widespread faucet assembly configured to reduce contaminants, including lead, within waterways.
Faucets are typically controlled by either a single handle which utilizes a mixing valve to proportion the flow of hot and cold water to a faucet spout, or two handles which utilize individual valves to separately control the flow of hot water and cold water to the faucet spout. In the case of the standard prior art mixing valve, two inlets are provided, one each for the hot and cold water supplies. For two handle faucets, each valve typically includes a single inlet opening which fluidly communicates with the flow passageway of a valving member. One type of two handle faucet is a widespread faucet where the hot water valve, the cold water valve and the spout have no common base above the sink deck.
In an illustrative embodiment of the present disclosure, a faucet assembly reduces exposure of potable water to lead or other heavy metal contaminants that could potentially be dissolved from a conventional faucet. Illustratively, a closed ceramic-type valve cartridge mates with an inert polymeric waterway. The waterway illustratively includes supply conduits configured to connect directly to the plumbing system through conventional hot and cold water stops. Water leaving the valve cartridge is directed through non-metallic materials until it exits the faucet through an aerator, thereby reducing, if not eliminating, the potential for contamination of heavy metals.
According to an illustrative embodiment of the present disclosure, a faucet assembly includes a waterway having a conduit with opposing first and second ends, and a base coupled to the first end of the conduit. A valve assembly is operably coupled to the base and is in fluid communication with the conduit. A valve body includes a sidewall receiving the base of the waterway. The valve assembly is operably coupled to an upper end of the valve body, and the conduit extends through a lower end of the valve body. A first retainer is integral with the sidewall of the valve body and is configured to prevent movement of the base of the waterway toward the upper end of the valve body. A second retainer is integral with the sidewall of the valve body and is configured to prevent movement of the base of the waterway toward the lower end of the valve body.
In a further illustrative embodiment of the present disclosure, a faucet assembly includes a waterway having a conduit with opposing first and second ends, and a base coupled to the first end of the conduit. A valve assembly is operably coupled to the base and is in fluid communication with the conduit. A valve body includes a sidewall receiving the base of the waterway. The valve assembly operably couples to an upper end of the valve body, and the conduit extends through a lower end of the valve body. A first orientation member is supported by the base of the waterway. A second orientation member is operably coupled to the first orientation member to facilitate proper rotational orientation of the base of the waterway.
According to another illustrative embodiment of the present disclosure, a widespread faucet assembly includes a hot water control valve, a cold water control valve, a hot water outlet conduit including an end in fluid communication with the hot water control valve, and a cold water outlet conduit including an end in fluid communication with the cold water control valve. A fluid connector includes a hot water inlet port, a cold water inlet port, and an outlet port. The end of the hot water outlet conduit is received within the hot water inlet port, and the end of the cold water outlet conduit is received within the cold water inlet port. An outlet conduit includes an end received within the outlet port of the fluid connector. A delivery spout is positioned intermediate the hot water control valve and the cold water control valve, the outlet conduit being received within the delivery spout.
According to a further illustrative embodiment of the present disclosure, a faucet assembly includes a waterway having a conduit with an end, and a base coupled to the end of the conduit. A valve assembly is operably coupled to the base and is in fluid communication with the conduit. A valve body includes a sidewall receiving the base of the waterway and including a retaining recess. A retainer is supported by the base and is configured to be received within the retaining recess of the valve body to couple the base with the valve body.
In yet another illustrative embodiment of the present disclosure, a widespread faucet assembly includes a mounting base having a first opening and a second opening spaced apart from the first opening. The first opening and the second opening each include an alignment member, the mounting base configured to be operably coupled to a sink deck. A first mounting shank is received within the first opening and includes a cooperating member to cooperate with the alignment member of the first opening for rotationally aligning the first mounting shank within the mounting base. A second mounting shank is received within the second opening and includes a cooperating member to cooperate with the alignment member of the second opening for rotationally aligning the second mounting shank within the mounting base.
According to a further illustrative embodiment of the present disclosure, a faucet assembly includes a waterway having a conduit with an end, and a base coupled to the end of the conduit. A valve assembly is operably coupled to the base and is in fluid communication with the conduit. A valve body receives the base of the waterway, and a coupler is received within the valve body. The coupler includes a first retainer coupled to the base of the waterway, and a second retainer coupled to the valve body.
Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the invention as presently perceived.
The detailed description of the drawings particularly refers to the accompanying figures in which:
The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.
Referring initially to
The water control assemblies 20 and 22 include handles 14 and 16 operably coupled to stems 24a, 24b of valve assemblies or cartridges 26a, 26b, respectively. Rotation of the handles 14 and 16 cause corresponding rotation of the valve stems 24a, 24b of the valve cartridges 26a, 26b to control the flow of hot and cold water therethrough. In one illustrative embodiment, rotation of the stem 24a, 24b causes corresponding rotation of an upper valve member 25 relative to a lower valve member 27 to control water flow from an inlet or supply conduit 36 to an outlet conduit 38 (
A waterway 28 is operably coupled to the valve cartridge 26 and illustratively includes a coupler or base 30 fluidly coupled to first ends 32 and 34 of inlet or supply tube or conduit 36 and outlet tube or conduit 38, respectively. A gasket 39 illustratively seals the valve cartridge 26 to the base 30 (
In one illustrative embodiment, the base 30 of each waterway 28 is an overmold formed of a polymer. More particularly, the base 30 may be overmolded about the first ends 32 and 34 of the supply conduit 36 and the outlet conduit 38. In a further illustrative embodiment, the supply conduit 36 and the outlet conduit 38 are formed of a polymer. Illustratively, both the base 30 and the conduits 36 and 38 may be formed of a polyethylene which are cross-linked after the overmolding process, thereby forming a cross-linked polyethylene (PEX). Additional details of such an illustrative process are disclosed in U.S. patent application Ser. No. 11/700,634, filed Jan. 31, 2007, entitled “Faucet including a Molded Waterway Assembly.”
As further detailed herein, each base 30 is illustratively formed of a flowable material overmolded around ends 32 and 34 of respective supply conduits 36, 38. While any suitable material may be used to form base 30, a polymer, including thermoplastics and thermosets, may be utilized in the illustrative embodiment. In one illustrative embodiment, each base 30 is formed of a polyethylene which has been overmolded around the ends 32, 34 of respective conduits 36, 38 and subsequently cross-linked to form PEX. In certain illustrative embodiments, reinforcing members, such as glass fibers, may be provided within the polyethylene of each base 30.
A valve body or mounting shank 54 includes a cylindrical sidewall 56 and is supported within a mounting opening 58 of the sink deck 12. While the valve body 54 is illustratively formed of a metal, such as brass, other suitable materials may be substituted therefor. The valve body 54 receives the base 30 of the waterway 28 and the valve cartridge 26 is operably coupled to an upper end 60 of the valve body 54. More particularly, a bonnet nut 61, illustratively formed or brass, threadably engages external threads 63 formed at the upper end 60 of the valve body 54. The inlet and outlet conduits 36 and 38 extend through a lower end 62 of the valve body 54.
With reference to
In the illustrative embodiment, the first retainer 64 comprises a radially extending flange or annular lip 68 extending radially inwardly from the inner surface 70 of the sidewall 56 of the valve body 54. The flange 68 engages an annular upper surface 72 of the base 30. The second retainer 66 is illustratively formed by bending radially inwardly the lower edge 74 of the sidewall 56 of the valve body 54. Illustratively, a spacer 76 extends between the second retainer 66 and the base 30. The spacer 76 illustratively is formed of an acetal copolymer, such as Celcon® M90™ available from Ticona of Florence, Ky. The spacer 76 includes a substantially cylindrical sidewall 78 coaxially received within the sidewall 56 of the valve body 54. Diametrically opposed alignment tabs 80 extend radially outwardly from the lower end 82 of the spacer 76 and are configured to be received within cooperating notches 84 within the valve body 54 for proper rotational alignment therebetween.
During assembly, the base 30 is first inserted from the lower end 62 of the valve body 54, followed by the spacer 76 until it meets the base 30 of the waterway 28. Standing edge 74 of brass from the valve body 54 is then bent or rolled over in a metal forming operation to trap the spacer 76 and to apply an upward load to the base 30 via the spacer 76, thereby retaining the base 30 and the spacer 76 between the retainers 64 and 66. While the illustrative figures show a pair of circumferentially spaced apart edges 74 rolled radially inwardly, it should be appreciated that any suitable number of spaced apart edges or tabs may be used to restrain the spacer 76.
As shown in
The spacer 76 cooperates with the waterway 28 to facilitate proper rotational alignment or orientation of the waterway 28 in the valve body 54 and, as such, facilitating proper alignment or orientation of the valve cartridge 26a to the body 54. More particularly, the base 30 of the waterway 28 should be properly aligned with the valve body 54 such that the mating valve cartridge 26a is properly aligned with the valve body 54. The valve cartridge 26a includes diametrically opposed alignment tabs or keys 92 which are received within cooperating recesses or notches 94 formed at the upper end 60 of the valve body 54, such that the handle 14 is properly aligned for use. In the illustrative embodiment, an oval shaped protrusion or projection 96 extends downwardly from the base 30 of the waterway 28 to engage in a modified oval shaped recess 98 formed in an upper end 100 of the spacer 76. A center portion 102 of the oval recess 98 is further extended generally radially outwardly to allow the water connection nut 44 to pass through the spacer 76 while allowing adequate support for the base 30 on the support surface 104 of end of the spacer 76. As such, the base 30 of the waterway 28 is keyed to the spacer 76 and, subsequently to the valve body 54.
As noted above, tabs 80 on the spacer 76 engage with notches 84 within the body 54 to rotationally restrain the spacer 76 to the body 54 which, in turn, keys the base 30 to the valve body 54. Misalignment between the base 30 and the valve cartridge 26a is illustratively centered using ramped tabs 106 on the cartridge 26a engaging with tapered slots 108 on the base 30.

The valve body 206 has a bore 210 machined from the top thereby leaving a ledge or annular lip 212 for supporting the waterway base 230 of the waterway assembly 228 (
A pair of diametrically opposed retainers 216 are illustratively integrally formed within an outer portion 218 of the base 230 and are configured to snap into slots 220 machined into the sidewall 208 (
The valve bodies 206 may be mounted using mounting nuts 257, illustratively formed of brass. Illustratively, the cartridge 26 is held in place through a bonnet nut 61. O-ring 88 is received within peripheral channel 90 of the base 230 and provides a secondary radial seal to keep water from leaking under the sink deck 12.
The sidewalls 208 of valve bodies 206 illustratively include flats 232 to define a minor diameter or transverse dimension 233 (
Flats 248 and 250 within the openings 238 defined by the support member 240 and the bracket 242 engage with the flats 232 on the respective sidewalls 208a, 208b to align the valve body 206a, 206b so the handles 14 and 16 will be oriented correctly above the sink deck 12, and to provide additional torsional resistance for the valve body 206a, 206b when torque is supplied to the handles 14 and 16. Flexible retainers 252 are supported by the support member 240 of the mounting base 236 and engage with the external threads 253 of the respective shank 208a, 208b. The retainers 252 include lips 254 having a helical edge surface 256 to mate with the valley portion (minor diameter) of threads 253 of the shank 208a, 208b. An inclined surface 258 on lips 254 permits upward movement of the retainer 252 relative to the threads. After the shanks 208a, 208b are drawn through the holes in the sink deck 12, the mounting base 236 is aligned and pushed up from below onto the shanks 208a, 208b below the surface of the sink deck 12. The retainers 252 engage with the threads 253, thereby allowing the mounting base 236 to stay in position as desired. A mounting nut 257 is then threaded up to the shank 208a, 208b against the lower surface of the bracket 242 thereby mounting the valve bodies 206a, 206b in place.
A delivery spout assembly 260 illustratively includes a small diameter threaded shank 262 (illustratively a ½-18 threaded tube) with an opening 264 extending therethrough. The opening 264 is configured to slidably receive a lift rod 266 for a pop-up drain assembly (not shown). The spout assembly 260 may be mounted using a brass nut 268 threadably received on the shank 262 and engaging the lower surface of the bracket 242 of the mounting base 236. A mounting member 270 is illustratively coupled to the spout assembly 260 through fasteners, such as bolts 272, and guides the outlet conduit 120 relative to the lift rod 266. The outlet conduit 120 is received within the delivery spout 18′ in a manner similar to that detailed above.
A fluid connector or manifold 276 fluidly couples ends of the conduits 38a, 38b, and 120. Illustratively, the manifold 276 includes receiving bores 278 each having a quick connect fitting 152, such as the Speedfit® fitting detailed above.
