Description

BACKGROUND AND SUMMARY OF DISCLOSURE

Dual-layered hoses having an overbraiding and a resilient interior tube are well known in the art of faucets, especially kitchen faucets with pullout wands. The overbraiding, usually constructed from interwoven nylon, polymeric, or metal threads, forms a supportive external layer for the resilient tube. This combination allows a user to flex and deform the hose when adjusting the water stream. While nylon, polymeric, or metal threads are typically used for the overbraiding, other materials can be used or combined in the braid. An illustrative hose assembly is described in US Patent Application Publication No. 2009/0126820 to Thomas et al., the disclosure of which is expressly incorporated by reference herein.

Further, since the hose has the overbraiding layer over the tube, there can be a narrow space between the overbraiding and the tube that can facilitate the passage of thread-like material along the length of the hose. Both the interweaving of different materials and the feeding of fibers and wiring between the layers make beneficial modifications to the hose possible.

For example, optical fibers can be as thin as a strand of human hair and they possess thread-like qualities that make them adaptable to the overbraiding of a faucet hose. Optical fibers can transmit light to provide both decorative and functional uses. Usually constructed of either transparent glass or plastic, they can be made to be flexible and deformable. These fibers can both transmit light between the two ends of the fiber and/or exteriorly along the axial exterior of the fiber.

Further, activation sensors may be desired in electronic faucets and require coupling to power sources and/or controllers through electrical wires. In certain embodiment faucets, it is desired to provide sensors on pull-out sprayheads removably supported by a delivery spout. As such, it is desired for electrical wires to pass along the hose in a protected and aesthetically pleasing manner.

The present disclosure provides an improved faucet hose by adding energy conducting conduits, such as optical fibers and/or electrical wires along a sprayer hose.

In one illustrative embodiment, a water faucet hose assembly is provided. In one exemplary embodiment, the assembly includes a first fiber formed of a first material, a second fiber formed of a second material configured to conduct energy, the first fiber and the second fiber being interwoven with one another to define a braided exterior sheath defining a longitudinal axis.

In another illustrative embodiment, a water faucet hose assembly is provided. In one exemplary embodiment, the assembly includes an exterior sheath defining a longitudinal axis, a resilient interior tube concentrically received within the sheath, and a space defined between the sheath and said tube. The space extends parallel to the exterior sheath and the resilient interior tube. The assembly further includes at least one energy conducting conduit extending through the space. In a more particular embodiment, the exterior sheath is a polymer braid.

In another illustrative embodiment, a water faucet hose assembly is provided. In one exemplary embodiment, the assembly includes a resilient interior tube having a fluid conduit extending therethrough, an exterior sheath covering a length of the resilient interior tube, the exterior tube being constructed of braided threads, and at least one energy conducting conduit positioned between the exterior sheath and the resilient interior tube.

DETAILED DESCRIPTION OF THE DRAWINGS

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 elected for description have been chosen to enable one skilled in the art to practice the invention.

Faucet hoses can be modified either by interweaving fibers into the overbraiding or passing fibers and wiring along the hose length between the multiple layers of the hose. In general, referring to FIG. 1, hose assembly 10 is illustrated as including both tube 12 and overbraiding 14. Optical fiber 16 can extend along the length of hose 10 either by being interwoven with overbraiding 14 or being threaded through space 18. Also, referring to FIG. 3, wires for electrical components supported within a pullout sprayhead 24, such as a capacitive sensor 20 and an ultrasonic sensor 22, may extend through space 18 along with optical fiber 16.

Referring back to FIG. 1, tube 12 defines a fluid passageway 40 through which water flows in from a water source (not shown) and out through pullout sprayhead 24. Typically, tube 12 is constructed of a material that is water-impermeable, elastically deformable, and resilient, such as rubber, plastic, or another synthetic polymer. This resilience facilitates the flexibility that pullout sprayhead 24, for example, provides when obtaining different spray angles is desirable. In one illustrative embodiment, the tube 12 is formed of a cross-linked polyethylene (PEX).

Tube 12 may be subjected to significant water pressure when in use. Thus, overbraiding 14, constructed of braided threads, provides an outer reinforcing sheath or outer sleeve for tube 12. Hose assembly 10, combining tube 12 and overbraiding 14, is resiliently adaptable to the deformations that result from angling or bending hose 10 and the water pressure that builds up within tube 12.

Since overbraiding 14 is constructed of interconnected, illustratively interwoven or braided threads, various materials may be utlized in overbraiding 14. For example, nylon threads can be combined with threads of a different material having similar physical characteristics, such as polypropylene for example, to create an interwoven composite. Advantageously then, given this compatibility of overbraiding 14 with diverse materials, such as energy conducting conduits, illustratively an optical fiber 16, may be interwoven with the other threads in overbraiding 14 to extend along the length of hose 10.

Therefore, in one embodiment, referring to FIG. 2, optical fiber 16 is interwoven into the threads of overbraiding 14. By interweaving optical fiber 16, light can be distributed along overbraiding 14 in different ways. First, optical fiber 16 may transmit light from one end to the other to illuminate pullout wand 24 (shown in FIG. 3) at the spraying end. This “end-to-end” spanning transmits light virtually uninhibited toward outlet 28. Alternatively, or in addition to the first method, optical fiber 16 may also be nicked or notched along its axial length to decrease the internal reflection and allow light to escape radially outwardly through the outer surface of optical fiber 16. This “interspaced” lighting transmits several small beams of light along the length to provide an aesthetically pleasing, illuminated hose 10.

Optical fiber 16 can extend along the length of hose 10 in another manner. Referring back to FIG. 1, hose 10 has space 18 between tube 12 and overbraiding 14 that is of sufficient size to receive energy conducting conduits, such as thin electrical wires or fibers. Thus, in an alternate embodiment, instead of interweaving optical fiber 16 into overbraiding 14, optical fiber 16 may be positioned between overbraiding 14 and tube 12 along the length of hose 10. By “sandwiching” optical fiber 16 between overbraiding 14 and tube 12, this embodiment facilitates the transmission of light from one end of optical fiber 16 to the other to illuminate the end of pullout wand 24 and transmit light virtually uninhibited toward outlet 28. Referring to FIG. 2A, the optical fiber 16, and/or wires 27, 36, 38, are positioned in space 18 between overbraiding 14 and tube 12. In the exemplary embodiment illustrated in FIG. 2A, radial outlet 34 is an inlet for optical fiber 16 and/or wires 27, 36, 38 that intersects hose 10 at a location along the length of hose 10 that is past ferrule 30. Thus, ferrule 30 can still be crimped as usual without damaging the optical fiber 16, and/or wires 27, 36, 38.

Referring to FIG. 3, multiple wires may extend along the length of hose 10 allowing for a multi-sensor arrangement in pullout wand 24 with an optional fiber-optically transmitted light. In one illustrative embodiment, these wires connect electrode 26 to capacitive sensor 20, connect power and ground, 36 and 38, to ultrasonic sensor 22, and, optionally, transmit light out through pullout wand 24 via optical fiber 16. Space 18 is defined between overbraiding 14 and the exterior of tube 12 (represented by diagonal lines in FIG. 3) to allow the passage of these fibers or wires along the length of hose 10.

Referring further to FIG. 3, illustrative hose assembly 10 is further shown. Overbraiding 14 constitutes the exterior layer of hose 10 and covers tube 12 while providing space 18 between the inner surface of overbraiding 14 and the outer surface of tube 12. Advantageously, with wiring threaded through space 18, as illustrated and as will be described in further detail below, electrode 26 and ultrasonic sensor 22 can both be positioned conveniently within pullout wand 24.

With reference to FIGS. 4 and 5, while capacitive sensors are capable of both touch-sensing and proximity-sensing, capacitive sensor 20, in a simplified exemplary embodiment, detects the touching of pullout wand 24 to turn the water stream on. Electrode 26, contained within and in electrical communication with pullout wand 24, is electrically coupled to capacitive sensor 20 through a wire 27. Advantageously, electrode is positioned adjacent outlet 28 of pullout wand 24 such that the distance between the stream and the surface that a user touches has been minimized. In an exemplary operation, a capacitive signal is constantly transmitted from electrode 26 to capacitive sensor 20. When a user touches the exterior of pullout wand 24, this contact changes the capacitive signal that is transmitted to the capacitive sensor 20. Capacitive sensor 20 transmits a signal to a processor that controls the opening and closing of an electrically operable valve to turn the water stream on.

In an illustrative embodiment, ultrasonic sensor 22 turns the water stream on when an object comes within a predetermined proximity. Two wires, power 36 and ground 38, are threaded through space 18 along the length of hose 10 and connected to ultrasonic sensor 22, which is positioned in pullout wand 24. Advantageously, this threading through hose 10 allows for the simple construction of an easily accessible sensor not only for a user's hands, but also for objects placed in close proximity of ultrasonic sensor 22. In an exemplary operation, ultrasonic sensor 22 transmits a burst of ultrasonic waves at an object that are, in turn, deflected back toward the sensor 22. This deflected burst, also known as an echo, is detected by circuitry connected to ultrasonic sensor 22. This circuitry transmits the echo as a signal that identifies the proximity to a processor that controls the opening and closing of a valve to turn the water stream on.

By utilizing space 18 to receive the wiring for both capacitive sensor 20 and ultrasonic sensor 22, a more compact design for pullout wand 24 and hose 10 can be achieved. Having both sensors positioned near outlet 28 allows the sensors 20 and 22 to be close to the stream at outlet 28.

Referring now to FIGS. 1 and 2, in a typical faucet assembly, hose 10 has ferrule 30 that is usually crimped and fixedly connected to the end of hose 10 to secure hose 10 to water source adapter 32 that leads to water source (not shown). This crimping process form fits or bends the circular edges of ferrule 30 so that it is pressed like a collar against the end of hose 10 to secure tube 12 and overbraiding 14 to one another and to water source adapter 32.

However, when optical fiber 16 is interwoven into overbraiding 14 or any fibers or wires extend through space 18, such a form fit could damage those fibers and/or wires. Thus, referring now to FIG. 2, two ways for directing the fibers and wires to avoid damage from the crimping process are illustrated. First, radial outlet 34 is an inlet for fibers and/or wires that intersects hose 10 at a location along the length of hose 10 that is past ferrule 30. Thus, ferrule 30 can still be crimped as usual without damaging the fibers and/or wires. Second, an alternative crimping process can be utilized. Instead of pressing the full circular edges of ferrule 30 against hose 10, a portion of the circular edge is left uncrimped so that fibers and/or wires can extend through the remaining opened portion of the circular edge.

Referring now to FIG. 6, sprayer assembly 50 illustratively includes hose assembly 10 fluidly coupled to pullout sprayhead 52. Sprayer assembly 50 includes a water source adapter 32 configured to fluidly couple tube 10 to a water supply. Hose assembly 10 is configured to fluidly couple the water supply to one or more fluid outlets 28 in sprayhead 52.

Referring to FIGS. 14-16, hose assembly further includes at least one energy conducting conduit 78 extending in a space 18 defined between tube 12 and overbraiding 14 of tube assembly 10. Energy conducting conduit 78 is illustratively one or more wires, such as wires 78A, 78B, 78C, or an optical fiber. Referring to FIG. 6, conduit 78 exits space 18 at radial outlet 34. Radial outlet 34 is illustratively spaced apart from water source adapter 32. In the exemplary embodiment of FIG. 15, a ferrule 30 is positioned over the overbraiding 14 of hose assembly 10, securing water source adapter 32 to hose assembly 10. In the illustrative embodiment, ferrule 30 is positioned closer to the end of hose assembly 10 nearer the water source adapter 32 than the radial outlet 34. A second radial outlet 34 may be spaced apart from waterway adapter 61. In one exemplary embodiment, a ferrule 30 is positioned over the overbraiding 14 of hose assembly 10, securing waterway adapter 61 to hose assembly 10. In the exemplary embodiment, ferrule 30 is positioned closer to the end of hose assembly 10 nearer the waterway adapter 61 than the radial outlet 34.
