BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates generally to a showerhead and, more particularly, to a showerhead including a linear diverter.
An illustrative embodiment showerhead of the present disclosure provides for linear actuation of a diverter which maintains ergonomics as the diverter can be operated with one hand. An illustrative embodiment showerhead of the present disclosure aligns spray settings in order of apparent spray force. The settings are not defined by flow rate, but instead by the number of outlets and the size of those outlets. These two features, alone or in combination, provides more intuitive use by resembling common relative amplitude based adjustments such as volume sliders.
In an illustrative embodiment showerhead, a diverter is operated using a pivoting waterway with a compliant seal to open/close selective passageways arranged in an arcuate path and defining a plurality of spray functions. An actuator, such as a hand lever or slide button, is along a longitudinal axis of an input waterway and a handle of the showerhead. The lever can slide axially along the handle of the showerhead. A connecting rod extends between the lever and the pivoting waterway such that axial movement of the lever is translated into rotational movement of the pivoting waterway. An association of spray outlets to function settings is illustratively created wherein there may be a change of apparent spray force as the settings change. An association of function settings to passageway inlets or connecting ports may be organized circumferentially such that rotation of the pivoting waterway from a first to a last setting may increase or decrease apparent spray force.
According to an illustrative embodiment of the present disclosure, a showerhead includes a handle extending along a longitudinal axis, a water passageway received within the handle, and a sprayface supported by the handle and including a plurality of spray outlets. A directing plate includes a plurality of connecting ports, the connecting ports spaced apart in an arcuate path, each of the connecting ports providing fluid communication between the water passageway and an associated arrangement of spray outlets. A water diverter device includes a pivotable waterway having a diverter body with a proximal end and a distal end, an inlet adjacent the proximal end, and an outlet positioned distally of the inlet. The diverter body of the water diverter device is pivotable such that the outlet is moveable along the arcuate path, and the outlet is in selective communication with different ones of the connecting ports of the directing plate.
According to another illustrative embodiment of the present disclosure, a showerhead includes a handle extending along a longitudinal axis, a water passageway received within the handle, and a sprayface supported by the handle and including a plurality of spray outlets. A water diverter device includes a pivotable waterway having a diverter body with a proximal end and a distal end, an inlet adjacent to the proximal end, and an outlet positioned distally of the inlet. The diverter body of the water diverter device is pivotable such that the outlet is moveable along an arcuate path. A driving mechanism is operably coupled to the water diverter device adjacent to distal end of the diverter body, wherein the driving mechanism includes a user interface slidably supported for axial movement parallel to the longitudinal axis of the handle, a connector coupling the user interface to the distal end of the diverter body, and wherein axial movement of the user interface is translated into pivoting movement of the diverter body.
According to a further illustrative embodiment of the present disclosure, a showerhead includes a handle extending along a longitudinal axis, a water passageway received within the handle, and a sprayface supported by the handle and having a plurality of associated arrangements of spray outlets. A water diverter device is in fluid communication with the water passageway. A driving mechanism is operably coupled to the water diverter device. The driving mechanism includes a user interface slidably supported for axial movement parallel to the longitudinal axis of the handle, and a connector coupling the user interface to the water diverter device, wherein axial movement of the user interface moves the water diverter device to provide fluid communication between the water passageway and different ones of the plurality of associated arrangements of spray outlets.

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 selected for description have been chosen to enable one skilled in the art to practice the invention.
Referring initially to FIGS. 1-4, an illustrative showerhead 10 of the present disclosure includes a handle 12 supporting a sprayhead 14. The handle 12 extends along a longitudinal axis 16 and receives a water passageway or conduit 18. The water passageway 18 includes an inlet 20 and an outlet 22. A first or base portion 24 of the water passageway 18 supports the inlet 20 and extends parallel to the longitudinal axis 16. A second or arm portion 26 extends an angle to the base portion 24 and supports the outlet 22. A conventional fluid coupler 28 is secured to the inlet 20 and is sealed to the base portion 24 of the passageway 18 by an o-ring 30. The fluid coupler 28 is configured to fluidly couple with a conventional fitting of a flexible hose (not shown).
The illustrative sprayhead 14 includes a sprayface 32 having a plurality of spray outlets 34a, 34b and 34c configured to discharge water generally parallel to a center sprayhead axis 36 extending perpendicular to the sprayface 32. The illustrative embodiment showerhead 10, the sprayface 32 extends generally parallel to the handle 12, such that the sprayhead axis 36 extends generally perpendicular to the longitudinal axis 16.
As further detailed herein, a plurality of different sets of spray outlets 34a, 34b and 34c are arranged in the sprayface 32. Illustratively, a first set of spray outlets 34a are circumferentially spaced in an annular arrangement proximate a center of the sprayface 32, a second set of spray outlets 34b are circumferentially spaced in an annular arrangement radially outwardly from the first set of spray outlets 34a, and a third set of spray outlets 34c are circumferentially spaced in two annular arrangements radially outwardly from the second set of spray outlets 34b.
The sprayface 32 is illustratively coupled to a rear housing or shell 38 that may be integrally formed with the handle 12. The sprayface 32 and the rear housing 38 (including the handle 12) may be formed of a polymer. Conventional means, such as fasteners, adhesives or ultrasonic welding, may secure the sprayface 20 to the rear housing 38. Illustratively, the sprayhead 14 includes a cylindrical sidewall 40 extending rearwardly from the sprayface 20 and including an arcuate extension 42. The arcuate extension 42 cooperates with an arcuate extension 44 of the rear housing 24. Together, the arcuate extensions 42 and 44 define a cylindrical side wall 46 extending a full circumference of 360 degrees.
With reference to FIGS. 3-7B, the illustrative sprayhead 14 further includes a flow director, such as a directing plate 50 which is supported in spaced relation to the sprayface 32. A water chamber 52 is defined between the sprayface 32 and the directing plate 50. The directing plate 50 is positioned intermediate the sprayface 32 and a support or cover plate 54. The directing plate 50 may be formed of a polymer, and secured to the sidewall 40 of the sprayhead 14 in a conventional manner, such as via adhesives or ultrasonic welding. In certain illustrative embodiments, the sprayface 20, the sidewall 40 and the directing plate 50 may be integrally formed as a single piece. The directing plate 50 illustratively includes an inlet 56 fluidly coupled to an outlet 58 via a fluid passageway 60 (arrows 61 representing water flow in FIG. 5).
The cover plate 54 may be formed of a polymer and secured to the directing plate 50 via conventional means, such as fasteners 62 received within threaded projections 63. Openings 64 in the rear housing 24 provide clearance for the fasteners 62. Alternatively, adhesives or ultrasonic welding may be used to secure the cover plate 54 to the sprayface 20.
With reference to FIGS. 7A and 7B, the illustrative water chamber 52 includes separate chamber portions or passageways 52a, 52b and 52c. A plurality of passageway inlets or connecting ports 65, 66a, 66b and 66c extend through the directing plate 50. The connecting ports 65, 66a, 66b and 66c are spaced apart in an arcuate path 68 (FIG. 9). The connecting port 65 provides fluid communication between the water passageway 18 and associated arrangement of spray outlets 34b via chamber portion 52b. Each of the connecting ports 66a, 66b and 66c provides fluid communication between the water passageway 18 and an associated arrangement of spray outlets 34a, 34b and 34c via chamber portions 52a, 52b and 52c, respectively. The outlet 22 of the water passageway 18 is in fluid communication with the inlet 56 of the directing plate 50 defined by an annular boss 70. An o-ring 71 is received around the boss 70 to seal the inlet 60 of the directing plate 50 to the outlet 22 of the water passageway 18.
With reference to FIGS. 9 and 10, the first or inner chamber portion 52a is in fluid communication with the spray outlets 34a and the connecting ports 66a. The second or intermediate chamber portion 52b is in fluid communication with the spray outlets 34b and the connecting ports 66b. An arcuate first or inner wall 74 separates the first chamber portion 52a from the second chamber portion 52b. The third or outer chamber portion 52c is in fluid communication with the spray outlets 34c and the connecting ports 66c. An arcuate second or intermediate wall 76 separates the second chamber portion 52b and the third chamber portion 52c. The sidewall 40 defines the outermost periphery of the third chamber 52c.
A water diverter device 82 is received with the sprayhead 14 and illustratively includes a pivotable waterway 84 supported by the directing plate 50. With reference to FIGS. 11 and 12, the pivotable waterway 84 may include a diverter body 86 having a proximal end 88 and a distal end 90. An inlet 92 is positioned adjacent the proximal end 88, and an outlet 94 is positioned distally of the inlet 92. A fluid passageway 93 extends within the diverter body 86 between the inlet 92 and the outlet 94 (arrows 95 represent water flow in FIGS. 6 and 11).
With reference to FIGS. 3, 4, 9, 11 and 12, the body 86 of the water diverter device 82 is pivotable about the inlet 92, such that the outlet 94 is moveable along the arcuate path 68 (FIG. 9). As such, the outlet 94 of the diverter body 86 is in selective communication within different ones of the connecting ports 65, 66a, 66b, 66c of the directing plate 50. More particularly, the inlet 92 of the diverter body 86 is in fluid communication with the outlet 58 of the directing plate 50.
With reference to FIGS. 7A and 12, the outlet 58 of the directing plate 50 is illustratively defined by an outlet boss 96 including a plurality of circumferentially spaced outlet ports 97. O-rings 98 illustratively provide a seal between the outlet boss 96 and the inlet 92 of the diverter body 86. Circumferentially spaced inlet ports 99 are defined within a cylindrical sidewall 101 of the inlet 92. Rotational alignment of the outlet ports 97 of the outlet boss 96 and the inlet ports 99 of the sidewall 101 fluidly couple the outlet 58 with the inlet 92. As such, the outlet boss 96 of the directing plate 50 fluidly and pivotably couples with the inlet 92 of the pivotable waterway 84. The outlet boss 96 of the directing plate 50 and the inlet 92 of the pivotable waterway 84 define a waterway pivot axis 100 about which the diverter body 86 of the pivotable waterway 84 rotates. As shown in FIGS. 8A-8F, the pivot axis 100 of the pivotable waterway 84 is offset from the center sprayhead axis 36.
Illustratively, the pivotable waterway 84 of the water diverter device 82 supports a compliant seal 102 to open/close each connecting port 66a, 66b and 66c to the desired spray setting along the arcuate path 68. More particularly, the outlet 94 illustratively includes a compliant seal 102 to cooperate with a rear surface 104 of the directing plate 50, thereby providing a seal between the outlet 94 of the diverter body 86 and selective connecting ports 66a, 66b and 66c. The compliant seal 102 illustratively includes a gasket 106 having a resilient cup 108 (e.g., formed of an elastomer) defining an opening 110. A spring 112 is operably coupled to the cup 108 to bias the gasket 106 toward the rear surface 104 of the directing plate 50. The connecting ports 66a, 66b and 66c are shaped to cooperate with the opening 110 of the gasket 106 (i.e., the shape of the cup 108 and the position of the opening 110 in any particular function, for example, as shown in FIGS. 8A-8F). The design is configured to maximize the area between the opening 110 and respective connection port(s) 66a, 66b and 66c (e.g., to reduce flow restriction), while minimizing the potential risk for cross-function leakage (e.g., from one function to next function).
A spring biased detent 116 is supported by the diverter body 86 distally of the outlet 94. The detent 116 includes a pin 118 operably coupled to a spring 120 for biasing the pin 118 toward the directing plate 50. With reference to FIG. 9, the detent 116 is configured to be received within a selected retaining recess 122a, 122b, 122c, 122d, 122e and 122f formed in the rear surface 104 of the directing plate 50. The retaining recesses 122a, 122b, 122c, 122d, 122e and 122f are positioned in an arcuate path 124 extending parallel to the arcuate path 68 of the connecting ports 66a, 66b and 66c. More particularly, each retaining recess 122a, 122b, 122c, 122d, 122e and 122f corresponds to an operating mode of the showerhead 10 as defined by the outlet 94 of the water diverter device 82 cooperating with a corresponding connecting port(s) 66a, 66b and 66c of the directing plate 50.
With reference to FIGS. 3 and 4, the driving mechanism 130 is operably coupled to the water diverter device 82 adjacent the distal end 90 of the diverter body 86. The driving mechanism 130 illustratively includes a user interface 132, such as a slide or carriage 134 coupled to a button 136, slidably supported for axial movement parallel to the longitudinal axis 16 of the handle 12. The carriage 134 is aligned with the axis 16 of the water passageway 18 and handle 12, and configured to slide axially along the handle 12. The button 136 is configured to move within a slot 137 formed in the handle 12. More particularly, the carriage 134 is illustratively configured to slide along rails 138 supported by the water passageway 18 by a user sliding the button 136 up and down within the slot 137.
With reference to FIGS. 3, 4 and 8A-8F, a connector 140 extends between the carriage 134 and the pivotable waterway 84 such that axial movement of the carriage 134 is translated into rotational movement of the pivotable waterway 84. More particularly, the illustrative connector 140, may include a connecting arm 141, coupling the user interface 132 to the distal end 90 of the diverter body 86, wherein axial movement of the user interface 132 is translated into pivoting movement of the diverter body 86. The connecting arm 141 illustratively includes a first end 142 supported by a first pivot coupling 144, and a second end 146 supported by a second pivot coupling 148.
The first pivot coupling 144 is illustratively defined by a boss 150 at a distal end 152 of the carriage 134 received within an opening 154 proximate the first end 142 of the connecting arm 140. The second pivot coupling 148 is illustratively defined by a boss 156 at the distal end 90 of the diverter body 86 received within an opening 158 proximate the second end 146 of the connecting arm 141. The distal end 90 of the diverter body 86 includes a circular projection 160 configured to be rotatably supported within a recess 162 of the cover plate 54, thereby providing additional support to the diverter body 86.
In operation, spray force through the spray outlets 34a, 34b and 34c illustratively changes (e.g., increases) as the outlet 94 of the water diverter device 82 moves along the arcuate path 68 in fluid communication which successive ones of the connecting ports 66a, 66b and 66c. As further detailed herein, the spray outlets 34a, 34b and 34c illustratively include a plurality of different sets of spray outlets 34a, 34b and 34c having different cross-sectional flow areas to provide different spray forces. In one illustrative embodiment, the first annular set of spray outlets 34a includes five circumferentially spaced spray outlets 34a, and the second annular set of spray outlets 34b includes eight circumferentially spaced spray outlets 34b. The third annular set of spray outlets 34c illustratively includes an inner ring of twenty-four spray outlets 34c and an outer ring of twenty-four spray outlets 34c. It should be appreciated that the arrangement, number and size of the spray outlets 34 may vary.
With reference to FIGS. 8A-10, an illustrative operation of the diverter device 82 of the showerhead 10 is shown. FIG. 8A shows the diverter device 82 in a first mode of operation where water is substantially, but not entirely, blocked from flowing through any of the spray outlets 34a, 34b and 34c. More particularly, this mode may be called an “off”, “pause” or “trickle” mode where limited water flows out of spray outlets 34b. As shown, the outlet 94 of the pivotable waterway 84 is sealed with the rear surface 104 of the directing plate 50 thereby preventing water flow to any of the connecting ports 66a, 66b and 66c. However, the outlet 94 of the diverter device 82 is in fluid communication with the connecting port 65 which provides restricted water flow to the chamber portion 52b. As such, limited water flows through the chamber portion 52b and out spray outlets 34b. In the first mode of operation of FIG. 8A, the flow path between the diverter body 86 is restricted since the inlet ports 99 of the inlet 92 are only partially aligned with the outlet ports 97 of the outlet 58, and/or the connecting port 65 in fluid communication with the chamber portion 52b is of reduced size. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122a of the directing plate 50.
FIG. 8B shows the diverter device 82 in a second mode of operation where water flows through spray outlets 34a. More particularly, the diverter body 86 of the pivotable waterway 84 is pivoted about the pivot axis 100 defined by the inlet 92 (clockwise from FIG. 8A) such that the outlet 94 is fluidly coupled to the connecting port 66a. In an illustrative embodiment, the diverter body 86 in FIG. 8B is pivoted by approximately 15 degrees from the position shown in FIG. 8A. The outlet 94 of the diverter device 82 is in full fluid connection with the connecting port 66a. As such, water flows from the connecting port 66a through chamber portion 52a and out spray outlets 34a. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122b of the directing plate 50.
FIG. 8C shows the diverter device 82 in a third mode of operation where water flows through spray outlets 34a and 34b. More particularly, the diverter body 86 of the pivotable waterway 84 is pivoted about the pivot axis 100 defined by the inlet 92 (clockwise from FIG. 8B) such that the outlet 94 is fluidly coupled to the connecting ports 66a and 66b. In an illustrative embodiment, the diverter body 86 in FIG. 8C is pivoted by approximately 15 degrees from the position shown in FIG. 8B (i.e., approximately 30 degrees from the position shown in FIG. 8A). The outlet 94 of the diverter device 82 is in partial fluid connection with the connecting ports 66a and 66b. As such, water flows from the connecting ports 66a and 66b through chamber portions 52a and 52b, and out spray outlets 34a and 34b. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122c of the directing plate 50.
FIG. 8D shows the diverter device 82 in a fourth mode of operation where water flows through spray outlets 34b. More particularly, the diverter body 86 of the pivotable waterway 84 is pivoted about the pivot axis 100 defined by the inlet 92 (clockwise from FIG. 8C) such that the outlet 94 is fluidly coupled to the connecting port 66b. In an illustrative embodiment, the diverter body 86 in FIG. 8D is pivoted by approximately 15 degrees from the position shown in FIG. 8C (i.e., approximately 45 degrees from the position shown in FIG. 8A). The outlet 94 of the diverter device 82 is in full fluid connection with the connecting port 66b. As such, water flows from the connecting port 66b through chamber portion 52b and out spray outlets 34b. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122d of the directing plate 50.
FIG. 8E shows the diverter device 82 in a fifth mode of operation where water flows through spray outlets 34b and 34c. More particularly, the diverter body 86 of the pivotable waterway 84 is pivoted about the pivot axis 100 defined by the inlet 92 (clockwise from FIG. 8D) such that the outlet 94 is fluidly coupled to the connecting ports 66b and 66c. In an illustrative embodiment, the diverter body 86 in FIG. 8E is pivoted by approximately 10 degrees from the position shown in FIG. 8D (i.e., approximately 55 degrees from the position shown in FIG. 8A). The outlet 94 of the diverter device 82 is in partial fluid connection with the connecting ports 66b and 66c. As such, water flows from the connecting ports 66b and 66c through chamber portions 52b and 52c, and out spray outlets 34b and 34c. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122e of the directing plate 50.
FIG. 8F shows the diverter device 82 in a sixth mode of operation where water flows through spray outlets 34c. More particularly, the diverter body 86 of the pivotable waterway 84 is pivoted about the pivot axis 100 defined by the inlet 92 (clockwise from FIG. 8E) such that the outlet 94 is fluidly coupled to the connecting port 66c. In an illustrative embodiment, the diverter body 86 in FIG. 8F is pivoted by approximately 10 degrees from the position shown in FIG. 8E (i.e., approximately 65 degrees from the position shown in FIG. 8A). The outlet 94 of the diverter device 82 is in full fluid connection with the connecting port 66c. As such, water flows from the connecting port 66c through chamber portion 52c and out spray outlets 34c. In this position, the detent 116 of the pivotable waterway 84 is received within the retaining recess 122f of the directing plate 50.
The association of outlets 34a, 34b and 34c to functional settings is created such that there is a change of apparent force as the settings change. The association of settings to connecting ports 66a, 66b and 66c are organized circumferentially such that rotation from a first to a last setting increases or decreases in apparent spray force.
Assuming that flow rate (which can be controlled by a conventional flow regulator in series with the water passageway 18) and water pressure (which can be controlled by the water supply providing water to the water passageway 18) are substantially constant, then apparent spray force of water discharged from the spray outlets 34 can be approximated by the combined outlet flow area (FIG. 10) for each function as defined by the cross-sectional are of the combined active spray outlets 34. As the outlet flow area increases, the water flow velocity will decrease accordingly. Generally, the combined outlet flow area increases as a user slides the button 136 up, and decreases as a user slides the button 136 down. Illustrative combined outlet flow areas per function represented by FIGS. 8A-8F area provided in the following table.

It should be appreciated that the number, size and arrangement of spray outlets 34 may vary depending upon the desired effects of the discharged water (e.g., apparent spray force, spray coverage pattern and/or spray coverage area).
With reference to FIGS. 13-16, further illustrative showerheads 210, 310 are shown each including a sprayhead 214, 314 angled relative to the handle 212, 312, respectively. Many of the elements of showerheads 210, 310 are similar to those detailed above in connection with showerhead 10. As such, in the following description and accompany drawing figures, like reference numbers identify similar elements.
Illustratively, the sprayhead 214, 314 is angled downwardly toward the handle 212, 312 by approximately 15 degrees. In other words, the sprayhead axis 36 illustratively extends and an angle of approximately 75 degrees to the longitudinal axis 16. In such a design, a connector 240, 340 of the respective driving mechanism 230, 330 may be formed of a compliant material such that it has rigidity in tension and compression, but flexibility in bending moment to allow for the actuation of the respective pivotable waterway 284, 384 without binding the connector 240, 340.
FIGS. 13 and 14 show an illustrative driving mechanism 230 including a first compliant connector 240 in the form of a compliant arm or push rod 241. A first end 242 of the arm 241 is illustratively coupled to a slide or carriage 234 by a fastener or pin 249 received within an opening 254. A coupling block 255 is coupled to a second end 246 of the arm 241 via a first pivot coupling 244. The first pivot coupling 244 is illustratively defined by a bolt 257 extending through an opening 258 and threadably coupled with a nut 259. A second pivot coupling 248 is illustratively defined by the boss 256 of a diverter body 286.
As shown in FIG. 14, the compliant arm 241 is configured to bend between the handle 212 and the sprayhead 214. Opposing rails 261a and 261b receive and prevent buckling of the compliant arm 231. The compliant arm 241 may be formed of a resilient material, such as a thin strip of metal or polymer.
FIGS. 15 and 16 show an illustrative driving mechanism 330 including a second compliant connector 340 in the form of a flexible chain 341. The flexible chain 341 is illustratively formed of a plurality of links 343 (e.g., formed of a polymer) and connecting pins 345 (e.g., formed of metal). A first end 342 of the chain 341 is illustratively coupled to a slide or carriage 334 by a pin 335a received within an opening 354 and a link 343a of the chain 341. A coupling block 355 is coupled to a second end 346 of the chain 341 via a first pivot coupling 344. The first pivot coupling 344 is illustratively defined by a boss 357 supported at the second end 346 of the chain 341 and received within an opening 358 of the coupling block 355. A second pivot coupling 348 is illustratively defined by the boss 356 of the diverter body 386.
As shown in FIG. 16, the chain 341 is configured to bend between the handle 312 and the sprayhead 314. Opposing rails 361a and 361b receive and prevent buckling of the chain 331.
