Patent Application
20240216931
The present application relates generally to the field of valves and engines for water delivery devices, such as spray heads, showerheads, body sprays, hand showers and the like. More specifically, this application relates to selection engines and diverter valves that can directly route water between multiple sprays without having to cycle the device through a specific sequence.
Diverters providing flow between multiple nozzles for different spray patterns requiring a specific sequence can be annoying for users. Further, for sprayers that provide four or more different spray patterns, there is no way to directly select (e.g., select through a single manipulation or movement) each of the three non-active patterns without first moving (e.g., rotating a portion of, cycling, etc.) the sprayer through one or more undesired modes/spray patterns. Thus, it would be advantageous to provide a direct-access spray diverter that utilizes a configuration that allows a user to select any spray pattern at any time, regardless of the active pattern, without having to sequence or cycle through other spray patterns.
One exemplary embodiment relates to a water delivery device including an inlet connector, a sprayface assembly, and a selection engine. The inlet connector is configured to couple the water delivery device to a water supply. The sprayface assembly includes a plurality of nozzles that are configured to produce a plurality of spray patterns. The selection engine fluidly couples the inlet connector to the sprayface assembly and controls flow to each one of the plurality of nozzles to determine the spray pattern produced at the sprayface assembly. The selection engine is configured to switch directly from any one of the plurality of spray patterns to any other one of the plurality of spray patterns in response to a single actuation of the selection engine.
Another exemplary embodiment relates to a selection engine for a water delivery device. The selection engine includes a housing and a pivot plate. The housing defines a bore, an inlet port, and at least four outlet ports. The pivot plate is disposed in the bore and pivotably coupled to the housing. The pivot plate includes a plurality of plugs, each plug configured to selectively fluidly couple the inlet port to a respective one of the at least four outlet ports.
Yet another exemplary embodiment relates to a selection engine for a water delivery device. The selection engine includes a housing and a plurality of disks rotatably received in the bore. The inlet port is selectively fluidly coupled to a first pair of the at least four outlet ports by a first disk of the plurality of disks, and is selectively fluidly coupled to a second pair of the at least four outlet ports by a second disk of the plurality of disks, the first disk arranged in parallel with the second disk.
The disclosure will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements.
Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.
Disclosed herein are engines/valves (e.g., diverter valves, selection engines, etc.) for controlling water flow through water delivery devices, such as spray heads, showerheads, hand showers, body sprays and the like. The engines/valves of this application are able to control the flow to multiple outlets (e.g., at least four outlets), such as to provide multiple spray patterns, without having to sequence or cycle through the positions/modes corresponding to the intervening outlets/spray patterns. Instead, a user can directly select any one of the modes/positions with a single manipulation (e.g., movement) of the device.
For each water delivery device (e.g., the hand shower 100 of
The housing 107 has a body 170 extending between an inlet or first end 171 and an outlet or second end 172. The illustrated body 170 is cylindrical, however, the body 170 can have other shapes. The first end 171 includes one or more openings or inlets for receiving water, such as from a fluid passageway in the connector 310 for the showerhead 300 shown in
The base plate 106 couples to the first end 171 of the housing 107, such as through the fastener 151, another type of mechanical fastener, a weld, an adhesive, and/or another suitable fastening device or method. The base plate 106 couples the selection engine 105 to another element, such as the collar 313 for the showerhead 300 (see also
The diaphragm 108 includes one or more diaphragm members 180. As shown in
The pivot plate 109 includes a cylindrical body 190 having an inner surface 191 and an outer surface 192. A ball 193 extends from the outer surface 192 to engage a socket 112 in the outlet plate 110, such that the ball 193 and socket form a fulcrum (e.g., point) about which the pivot plate 109 freely pivots (i.e., rocks, tilts, etc.). The pivot plate 109 includes a post 194 extending away from the outer surface 192 for each outlet 111 in the outlet plate 110. The illustrated embodiment includes four posts 194, where each post 194 associates with one of the four outlets 111A-111D (see
The outlet plate 110 couples to the housing 107 in a fluid tight manner about an outer periphery of the outlet plate 110. The outlet plate 110 is disposed at an axial end of the body 170 and substantially covers the axial end. An optional sealing gasket can seal between the outer plate 110 and the housing 107. The outlet plate 110 includes one or more outlets 111 for outputting fluid flow, such as to a sprayface assembly. As shown in
The selection engine 105 may optionally include a mounting bracket 153 and/or a biasing member (e.g., spring). As shown, the mounting bracket 153 includes a first end, which couples to the base plate 106, and a second end, which couples the selection engine 105 to another device. For example, the second end of the mounting bracket 153 can include threads that thread to the collar 313, as shown in
During operation, relative movement between the outlet plate 110 and the pivot plate 109 moves one or more of the plugs 196 relative to its associated outlet 111 between the engaging and disengaging positions to prevent/allow, respectively, water flow through the associated outlet 111. The ball 193 and socket 112 connection allows relative free pivoting between the outlet plate 110 and the pivot plate 109, so that any number of plugs 196 can engage or disengage their respective outlets 111. Thus, for the embodiment shown in
The relative motion between the pivot plate 109 and the outlet plate 110 is configurable for manual articulation, such as by a user, or automatic articulation, such as using an electro-mechanical device. For example, articulation or motion (e.g., tilting) of the pivot plate 109 can be driven by a motion driving mechanism, such as one or more linear actuators, solenoids, motors, a combination of linear and rotary motions, etc. In some configurations, the pivot plate 109 may be disposed at a distance from the outlet plate 110, such that only one of the plugs 196 is not disposed in an outlet at any given time. The devices, such as the selection engine 105, can include a retention mechanism for retaining the pivot plate 109 and the outlet plate 110 is one or more relative positions. That is, the retention mechanism can hold the device in the current operational mode following a user changing the mode. If the device has, for example, four operational modes, the retention mechanism can hold the device in any one of the four modes until a user changes the mode of operation.
Notably, the selection engine 105 is configurable into other water delivery devices beyond the movable hand shower 100 shown in
The illustrated selection engine 405 includes a housing 406, a first disk 407 (e.g., upper disk), and a second disk 408 (e.g., lower disk). Each disk 407, 408 is independently rotatable relative to the housing 406 to control fluid flow through the selection engine 405.
The illustrated housing 406 has a hollow cylindrical body 460 having an inlet opening/port 461 in a first side, as shown in
At least part of each disk 407, 408 is positioned within the housing 406 to control fluid flow therethrough. As shown in
In a first or closed position of each wall 472, 482, the respective wall 472, 482 is proximate to and covers all (e.g., both) of the associated outlet ports 462 to block water from flowing through the outlet ports 462. In a second position (e.g., first open position), each wall 472, 482 covers a first outlet port 462 to block fluid flow therethrough while uncovering a second outlet port 462 to allow fluid flow therethrough. In a third position (e.g., second open position), each wall 472, 482 covers the second outlet port 462 to block fluid flow therethrough while uncovering the first outlet port 462 to allow fluid flow therethrough. In a fourth position (e.g., a third open position), each wall 472, 482 uncovers all (e.g., both of) the first and second outlet ports 462 to allow fluid flow through both outlet ports 462.
As mentioned and shown in
The selection engine 405 can optionally include one or more seals (e.g., gaskets). As shown in
As utilized herein, the terms “approximately,” “about,” “substantially,” and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. It should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described and claimed without restricting the scope of these features to the precise numerical ranges provided. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the disclosure as recited in the appended claims.
It should be noted that the term “exemplary” and variations thereof, as used herein to describe various embodiments, are intended to indicate that such embodiments are possible examples, representations, or illustrations of possible embodiments (and such terms are not intended to connote that such embodiments are necessarily extraordinary or superlative examples).
The term “coupled” and variations thereof, as used herein, means the joining of two members directly or indirectly to one another.
