SOAKER SINKS AND FLUID DISTRIBUTION ASSEMBLIES

An example soaker sink may include a sink basin that receives wash items therein and defines an inlet opening. The soaker sink may further include a manifold that defines an inlet opening, an interior that receives a fluid flow input via the inlet opening, and a plurality of outlets. The outlets may permit discharge of fluid from the interior of the manifold to the sink basin and may include at least a first outlet and may further include a common outlet dimension. The soaker sink may further include a pump fluidically coupled with the inlet opening of the sink basin and the inlet opening of the manifold to recirculate fluid from the sink basin to the manifold. A flow restrictor may be removably coupled with the first outlet and may be configured to modify a flow rate of the fluid discharged via the first outlet.

FIELD OF THE INVENTION

Embodiments of the present disclosure relate generally to washing devices and methods, components, and assemblies related thereto, and, in some embodiments, to soaker sinks.

BACKGROUND

Washing devices (e.g., sinks, dishwashers, etc.) are used in a variety of industries to clean and sanitize dishes, cutlery, pots and pans, and associated instruments for these industries. For example, restaurants, retailers, and the like may employ commercial soaker sinks that support or otherwise receive dishware therein (e.g., inside a basin, washing container, tub, etc.) and circulate water through the soaker sink in order to dislodge or otherwise remove items attached to the dishware. Applicant has identified a number of deficiencies and problems associated with washing devices. Through applied effort, ingenuity, and innovation, many of these identified problems have been solved by developing solutions that are included in embodiments of the present disclosure, many examples of which are described in detail herein.

BRIEF SUMMARY

As described above, various industries and use cases rely upon washing devices in order to properly clean various wash items. In some instances, such as in restaurants, other commercial retailers, and other residential and non-residential washing environments, soaker sinks may be used to facilitate this cleaning process. For example, a soaker sink may include a basin or other enclosure that is configured to support various items of dishware (e.g., plates, silverware, cutlery, pots, pans, other dishware and cookware, etc.) at least partially submerged in fluid supported by the basin. The fluid within the basin may be circulated so as to agitate or otherwise facilitate the removal of soils attached to the dishware and may leverage detergents and/or temperature in order to properly sanitize the dishware.

The present disclosure relates to soaker sinks and fluid distribution assemblies for such sinks. Soaker sinks may include fluid recirculation capabilities driven by one or more pumps that pull fluid from the sink basin into an inlet opening and redistribute fluid via a manifold to create agitation within the sink basin and thereby to clean the dishes. In some embodiments, removable flow restrictors may be used in outlets associated with the manifold to control the flow rate through each of a plurality of outlets and to collectively control the agitation in the sink basin.

The effectiveness of this recirculation and associated washing action within the soaker sink was conventionally thought to be predominately driven by the volumetric or mass flow rate of the fluid reentering the sink basin, and the solution was frequently increasing the size of the recirculation pump to increase agitation within the sink. Some embodiments of the present disclosure may operate to increase the velocity of the fluid entering the sink basin as an example mechanism for improving the effectiveness of the washing action within the sink basin, which may increase the net agitation and circulation flow within the sink without requiring a larger pump. As described herein, example implementations of embodiments of the present disclosure may utilize a fluid distribution assembly that includes a plurality of outlet openings that include an outlet dimension (e.g., cross-sectional area, diameter, or the like) capable of being controlled to adjust the flow rate and velocity of the outlet (e.g., by swapping flow restrictors having different dimensions). The outlet openings may further be equally spaced along a length of the manifold. The embodiments of the present disclosure may reduce the outlet dimension (e.g., cross-sectional area, diameter, or the like) for one or more outlets (e.g., via flow restrictors or narrower nozzle bodies) thereby increasing the velocity of the fluid discharged via the outlets to collectively control the washing action. By relying upon increased fluid discharge velocity as opposed to volumetric or mass flow rate, the embodiments of the present disclosure may reduce the operational requirements of other elements of the soaker sink while also providing an improved washing action. Due to the reduced volumetric or mass flow rate, embodiments of the present disclosure may, for example, reduce the required pump power output (e.g., leverage a smaller or less power intensive pump) and/or adjust the manifold body dimensions (e.g., reduce the cross-sectional area of the manifold body).

In order to address these problems and others, example implementations of embodiments of the present disclosure may additionally or alternatively utilize a fluid distribution assembly that provides in situ modification of fluid flow rate and may provide fluid flow outlets having adjustable fluid flow properties to adjust the relative flow between multiple outlets and/or collectively set fluid flow properties for the wash process. In some embodiments, the assembly may include a manifold that receives a fluid flow input (e.g., fluid recirculated by a pump from a sink basin) and outputs this fluid flow via a plurality of outlets in the manifold. To dynamically modify the flow rate of this fluid, the embodiments herein may leverage one or more flow restrictors that may be removably coupled with at least one outlet from amongst the plurality of outlets in the manifold. In some embodiments, these flow restrictors may be selectively used with various outlets to modify the relative properties (e.g., volumetric or mass flow rate, velocity, etc.) at which fluid is reintroduced to the sink basin. In some embodiments, the outlets may define different, fixed sizes configured to control the relative properties of the outlets.

Various embodiments described herein may be further configured to balance the discharge of fluid from the manifold such that the flow rate of each outlet into the sink basin is substantially uniform. In some embodiments, the relative position between the location at which fluid enters the manifold and the position at which fluid is discharged from the manifold may be varied along with a cross-sectional area of the outlets. In some embodiments, the narrowest cross-sectional area of each outlet, inclusive of the effects of any flow restrictors, may be the same if flow differences between nozzles are minimal or satisfactory to the user depending upon the structure and use of the soaker sink.

Accordingly, soaker sinks and associated fluid distribution assemblies are disclosed herein for providing variable and/or balanced fluid discharge for improved washing operations which were historically unavailable. The example embodiments of the present disclosure are described herein with reference to a commercial soaker sink configured to implement one or more elements of an example fluid distribution assembly. The present disclosure, however, contemplates that the devices, apparatuses, and systems described herein may be applicable to other implementations in which variable and/or balance fluid discharged is desired.

In an example embodiment, a soaker sink may be provided that includes a sink basin configured to receive one or more wash items therein where the sink basin defines an inlet opening. The soaker sink may further include a fluid distribution assembly that includes a manifold and a pump fluidically coupled with the inlet opening of the sink basin and an inlet opening of the manifold to recirculate fluid from the sink basin to the manifold for delivery of the fluid into the sink basin. The fluid distribution assembly may include a manifold defining an inlet opening, an interior configured to receive a fluid flow input via the inlet opening, and a plurality of outlets configured to permit discharge of fluid from the interior of the manifold to a basin of the soaker sink. The plurality of outlets may include at least a first outlet. In some embodiments, each of the each of the plurality of outlets including the first outlet may include or otherwise define a common outlet dimension and/or varied outlet dimensions so as to collectively control washing action within the basin of the soaker sink. In some embodiments, the fluid distribution assembly may further include a flow restrictor removably coupled with the first outlet, such that the flow restrictor is configured to control a flow rate of the fluid discharged via the first outlet.

In some embodiments, the first outlet may define a nozzle body that extends from a manifold body of the manifold that is configured to engage a wall of a sink basin to connect the first outlet with the sink basin.

In some further embodiments, the soaker sink may include a flow restrictor removably coupled with the first outlet, such that the flow restrictor is configured to modify a flow rate of the fluid discharged via the first outlet. The flow restrictor may be configured to be removably secured within the nozzle body. In such an embodiment the fluid distribution system may further include a fastener configured to removably secure the flow restrictor to the nozzle body.

In some embodiments, the fastener may include a leaf spring, and the nozzle body may define a groove configured to receive the leaf spring therein to removably secure the flow restrictor within the nozzle body.

In some further embodiments, an internal bore of the nozzle body may define a first cross-sectional area at its narrowest longitudinal point. An internal bore of the flow restrictor may define a second cross-sectional area at its narrowest longitudinal point smaller than the first cross-sectional area such that securing the flow restrictor within the nozzle body reduces the flow rate of the first outlet.

In some embodiments, the manifold may include a tubular manifold body, and the plurality of outlets may be equally spaced along a length of the tubular manifold body.

In some embodiments, the fluid distribution assembly may include a plurality of flow restrictors, including the flow restrictor where each of the plurality of flow restrictors is removably coupled with a respective one of the plurality of outlets, including the flow restrictor removably coupled with the first outlet.

In some further embodiments, a relative positioning between each of the plurality of outlets and respective dimensions defined by each flow restrictor to control a respective flow rate of each outlet may be configured to collectively balance the discharge of fluid from the interior of the manifold body such that the flow rate associated with each outlet is substantially uniform.

In some embodiments, the plurality of outlets may define the first outlet and a second outlet. In such an embodiment the manifold may define a first flow path from the inlet of the manifold to the sink basin via the first outlet and a second flow path from the inlet of the manifold to the second basin via the second outlet. The first outlet opening may be disposed closer to the inlet opening of the manifold than the second outlet opening, and the second flow path may define a narrowest cross-sectional area that is smaller than a narrowest cross-sectional area of the first outlet opening.

DETAILED DESCRIPTION

The present invention now will be described more fully hereinafter with reference to the accompanying drawings in which some but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. As used herein, terms such as “front,” “rear,” “top,” etc. are used for explanatory purposes in the examples provided below to describe the relative position of certain components or portions of components. Furthermore, as would be evident to one of ordinary skill in the art in light of the present disclosure, the terms “substantially” and “approximately” indicate that the referenced element or associated description is accurate to within applicable engineering tolerances.

Soaker Sink

With reference toFIGS.1-6, an example soaker sink100is illustrated. As shown, the soaker sink100may include a sink basin102configured to receive one or more wash items therein. The sink basin102may define or be otherwise formed by one or more walls, for example wall101, so as to define a location capable of supporting items and fluid therein. The soaker sink may thereby facilitate fully submerging the wash items for soaking and continuous washing. Although described herein with reference to a basin, the present disclosure contemplates that the sink basin102may refer to any location within which fluid and wash items may be supported within the appliance. In some embodiments, as shown inFIGS.1-6, the sink basin102may be at least partially open so as to allow access to the wash items supported by the sink basin102during operation (e.g., via an open top). In other embodiments, however, the sink basin102may instead define an enclosure that, via a door or otherwise, permits selective access to the interior of the sink basin102(e.g., a closed washing implementation). The sink basin102may further be in fluid communication (e.g., fluidically coupled) with one or more fluid supply lines (not shown) configured to provide fluid to the soaker sink100for use in the recirculation described herein (e.g., a freshwater inlet).

As described above, the sink basin102may be configured to receive or otherwise support one or more wash items (e.g., plates, silverware, cutlery, pots, pans, other dishware and cookware, etc.) therein. In some embodiments, the sink basin102may define one or more support structures (e.g., racks, shelves, etc.) upon which wash items may be placed (not shown). In doing so, the sink basin102may operate to properly distance items within the sink basin102to ensure proper fluid within, around, etc. these items. Although illustrated as a single, open structure, the present disclosure contemplates that the sink basin102may, in some embodiments, include various partitions, separators, or the like (not shown) configured to define separated locations within the sink basin102. In such an embodiment, the partitions, separators, etc. may be perforated or otherwise provide for fluid communication within the sink basin102to ensure proper fluid circulation as described above.

Still further, although illustrated as a distinct sink basin102, the present disclosure contemplates that the sink basin102may operate as part of a collection of basins or enclosures as part of the same soaker sink100or a plurality of interconnected soaker sink devices. As shown, the soaker sink100may, in some embodiments, be supported by a frame108such that the soaker sink operates as a standalone implementation. In other embodiments, however, the frame108, wall101, etc. may be configured to interface with components of another sink basin or soaker sink. Said differently, the present disclosure contemplates that the soaker sinker100may operate as a modular component as part of an integrated washing system. Therefore, in any embodiment, the present disclosure contemplates that the soaker sink100, sink basin102, frame108, wall(s)101, and/or the like may be dimensioned (e.g., sized and shaped) based upon the intended application of the system and/or may be portions of a larger device or system. By way of a nonlimiting example, the soaker sink100may be dimensioned such that the width (W) of the soaker sink100is approximately 36 inches to approximately 66 inches wide. In one example embodiment, a soaker sink100may be 66 inches wide and 21 inches deep. As described hereafter with reference toFIG.7AandFIG.12, the angle at which fluid is reintroduced into the sink basin102(e.g., via the plurality of outlets204) may also depend upon the associated dimensions of the sink basin102.

With reference toFIGS.1,5, and6, the sink basin102may also define an inlet opening106in fluid communication (e.g., fluidically coupled) with the sink basin102. As depicted, the inlet opening106may include a rectangular manifold coupled to a rectangular opening in a wall101of the sink basin with a cylindrical conduit coupled to the rectangular manifold. The rectangular base of the manifold may include a circular conduit therein, and the upper edges of the manifold may be sloped to match the shape of the angled wall above it as shown inFIGS.2-3. The cylindrical conduit of the inlet opening106connecting the inlet opening to a pump104(e.g., as shown inFIG.3). In order to allow for recirculation of fluid from the sink basin102within the soaker sink, the inlet opening106may be configured to permit fluid from the sink basin102to be drawn into the pump104. The inlet opening106as shown is positioned proximate a bottom surface of the sink basin102and covered by a perforated grate, filter, cover, etc. (e.g., as shown inFIGS.1,5). Such a grate may operate to prevent particulate matter from exiting the sink basin102and being drawn into the pump via the inlet opening106so as to mitigate or prevent damage to the pump104in fluid communication (e.g., fluidically coupled) with the inlet opening106(e.g., by preventing debris within the sink basin102from being drawn into and breaking the pump). Although illustrated as a single inlet opening106with an associated covering, the present disclosure contemplates that the inlet opening106may define a plurality of openings in one or more walls101of the sink basin102with or without accompanying manifolds connecting the sink basin to the pump based upon the intended application of the system100.

As described hereafter with reference toFIGS.7A-10, the soaker sink100may include a fluid distribution assembly200configured to receive fluid from the pump104and discharge the fluid into the sink basin102. The fluid distribution assembly200may define a manifold201that defines an interior (e.g. interior203inFIG.8) configured to receive a fluid flow input from the pump104via an inlet opening202. The manifold201may include a plurality of outlets204spaced along a length of the manifold that permit discharge of fluid from the interior of the manifold201to the sink basin102as described hereafter. In the depicted embodiment, the manifold201defines a generally cylindrical shape arranged parallel to and spaced from the wall101of the sink basin102. In some embodiments, the manifold201may be attached to, spaced from, integral with, or otherwise connected, directly or indirectly, with the wall101of the sink basin102.

The manifold201may also include other cross-sectional shapes, including but not limited to circular, rectangular, square, etc. Some embodiments described herein rely upon a manifold201having a plurality of outlets204having an outlet dimension (e.g., cross-sectional area, diameter, etc.) that may be the same or different, and that may be controllable to determine the collective flow rate and velocity of the fluid leaving the nozzles and to adjust the flow rate and velocity between nozzles, such that the plurality of outlets are configured to collectively control washing action within the basin of the soaker sink100. The outlet dimension may be defined by a diameter or cross-sectional area of one or more flow restrictors (e.g., flow restrictor300shown inFIG.9) as described herein, or by any other parameter of the flow restrictors that changes the flow rate and velocity of liquid through the outlet. In some embodiments, the outlets204may include a nozzle body205having a common internal diameter and the net diameter of the outlet may be adjusted by the one or more flow restrictors, such that each outlet has the same or a different controllable net outlet dimension as described herein. In some embodiments, the size of the outlet (e.g., with or without flow restrictors) may facilitate control of the velocity of the fluid entering the sink basin102and the flow rate of fluid entering the sink basin102as an example mechanism for improving the efficiency and effectiveness of the washing action within the sink basin102. The size of the outlets may collectively be adjusted to change the total velocity of fluid entering the sink basin, and the outlets may be adjusted individually to vary or synchronize the velocity of fluid entering the sink basin across each nozzle. In some embodiments, the volumetric or mass flow rate associated with such an implementation may be reduced while increasing or maintaining the velocity using the outlet configurations described herein, such that the dimensions of the manifold201may be reduced relative to conventional systems.

As shown inFIGS.1-5, the pump104of the soaker sink100may be in fluid communication (e.g., fluidically coupled) with the inlet opening106of the sink basin102and the inlet opening202of the manifold201(and thus the fluid distribution assembly200) to recirculate fluid from the sink basin102to the manifold201(and thus the fluid distribution assembly200) for delivery of the fluid back into the sink basin102to facilitate the recirculation action in the sink. In some embodiments, a heater chamber230may be connected within the recirculation assembly (e.g., between the pump104and manifold201as shown inFIG.3). The recirculation may create a washing action within the sink basin, whereby the fluid is continuously flowing in a generally circular path within the basin to remove debris from the wash items. As would be evident to one of ordinary skill in the art in light of the present disclosure, the pump104may be configured to provide suction, generate negative pressure within the sink basin102, positive displacement, or otherwise cause fluid transfer between the inlet opening106of sink basin102and the fluid distribution assembly200for delivery back into the sink basin via the outlets. As such, the present disclosure contemplates that the pump104may comprise one or more valve-less pumps, stem pumps, gravity pumps, velocity pumps, impulse pumps, positive displacement pumps, peristaltic pumps, or any combination thereof. In some embodiments, the pump104may be an impeller-based, fully enclosed, self-draining pump.

The present disclosure contemplates that the operating parameters (e.g., suction pressure, discharge pressure, pump speed, power, flow, head, etc.) and dimensions of the pump104may be varied based upon the intended application of the soaker sink100. Additionally, although illustrated with a single pump104, the present disclosure contemplates that any number of pumps at any location may be used by the soaker sink100to drive fluid recirculation as described herein. By increasing the velocity of the fluid entering the sink basin as an example mechanism for improving the effectiveness of the washing action within the sink basin as opposed to a reliance upon increased volumetric or mass flow rate, embodiments of the present disclosure may also reduce the operational requirements of the pump104. For example, the soaker sink102may leverage a smaller or less power intensive pump104while continuing to provide an improved washing action relative to conventional systems. By way of a nonlimiting example, the pump104may include a three-phase pump configured to output a flow rate of 200 gallons per minute regardless of sink size.

As shown inFIG.4, the sink basin102may further define a drain110configured to remove fluid from the sink basin102. By way of example, fluid may be continually recirculated from the sink basin102to the fluid distribution assembly101via the pump until a determined number of cycles has occurred, a period of time has expired, a predetermined soil level is reached in the washing fluid, and/or the like. Furthermore, the drain110may additionally or alternatively be used to remove fluid from the sink basin102in response to a contamination or other related hazard. In some embodiments, the drain110may be gravity fed, and in some embodiments, a separate drain pump (not shown) may be provided for draining the sink basin102. In order to prevent damage to components of the soaker sink100in instances in which fluid is absent from the system, the pump104may be powered off Although illustrated as a single drain110centrally located in a bottom surface of the sink basin102, the present disclosure contemplates that the sink basin102may employ any number of drains, outlets, exits, openings, etc. at any location.

Fluid Distribution Assembly

With reference toFIGS.7A-7B, a portion of the fluid distribution assembly200is illustrated with a portion of the example soaker sink100, which has been simplified for ease of viewing via, for example, removing the side walls of the sink basin and other components. As shown, the fluid distribution assembly200may include a manifold201that may define the inlet opening202, an interior (e.g., interior203inFIG.8) and a plurality of outlets204as described above. The fluid distribution assembly200may further include one or more flow restrictors (e.g., flow restrictors300shown inFIG.9) configured to modify the flow rate of one or more respective outlets204. As shown, the manifold201may comprise a tubular manifold body221such that the inlet opening202in the manifold201is located on an end of the tubular manifold body. The plurality of outlets204may be positioned along a length L of the manifold201, and the plurality of outlets204may thereby be different distances from the inlet opening202of the manifold and the pump104to each of the respective outlets.

In some embodiments, fluid flow may tend to travel through the outlets204farther from the inlet opening202and/or the pump104at a greater mass flow rate than the outlets closer to the inlet opening202and/or the pump104when all else is held equal with respect to the outlet dimensions. The fluid velocity in the manifold at each outlet may be related to the percentage of fluid that leaves the outlets, such that, in an instance in which all outlets are the same size and have the same cross-sectional flow area, the outlets farthest from the inlet opening202receive the highest flow rate (e.g., mass or volumetric flow rate) and the outlets closest to the inlet opening receive the least mass flow rate of fluid in such situations.

As described herein, various solutions are provided to control the flow rate through one or more outlets204and to provide an improved washing action within the sink basin102. With reference toFIGS.8-9, the outlets204of the manifold201may comprise nozzle bodies205extending from the manifold body221and into engagement with the wall101of the sink basin102. In some embodiments, the manifold body221may be directly coupled to the wall101with an opening connecting the manifold body directly with a corresponding opening in the wall, which opening may be the nozzle body. With reference toFIG.3, a manifold201is shown having an inlet opening202through which washing fluid is pumped by a pump104during recirculation from the sink basin.

Although illustrated herein as a tubular manifold body221having a circular cross-sectional shape substantially uniform in cross-sectional area along its length, the present disclosure contemplates that the cross-sectional area, length, shape, or any other parameter of the manifold201may be varied based upon the intended application of the soaker sink100. For example, a rectangular cross-section may be used instead of a circular cross-section. The inlet opening202may similarly be dimensioned (e.g., sized and shaped) based upon the intended application of the soaker sink100. The inlet opening202may also be positioned at any location of the manifold201and/or may supply fluid to the interior of the manifold201from a plurality of locations. For example, in some embodiments, the inlet opening may be positioned on an opposite end of the tubular manifold body, such as in instances in which the pump104, heater chamber230, etc. are positioned on an opposing side of the sink basin102for ease of use, installation, or otherwise as chosen or required by the particular user or location. The corresponding outlet dimensions may thereby be adjusted depending upon the manifold structure and inlet opening(s) position to achieve the various configurations described herein. Additionally or alternatively, in some embodiments, the inlet opening202may be configured to supply fluid to each end of a tubular manifold body (e.g., via a collection of channels, conduits, or the like). In some embodiments, the outlet dimensions of the plurality of outlets204and/or the flow restrictor(s)300may be configured based, at least in part, on the inlet opening202to produce a predetermined flow pattern within the sink basin102. In some embodiments, the outlets may define different, fixed sizes configured to control the relative properties of the outlets.

The manifold201may further define a plurality of outlets204including at least a first outlet206. By way of example, the manifold201may define a first outlet206, a second outlet208, . . . , a Nthoutlet. Said differently, the present disclosure contemplates that the number of outlets204defined by the manifold201may vary based upon the width of the soaker sink200and/or the intended application of the soaker sink200and may further be varied (e.g., increased or decreased) to adjust the flow rate or position of the fluid discharged by the outlets204. For example, in some embodiments, each outlet204may be spaced a predetermined distance from each other. For example, the soaker sink200may use a 6-7 inch (e.g., about 6.8 inches) spacing between adjacent outlets, for example being measured from the center out to the sides of the sink. The number of outlets may be determined by the width of the soaker sink200, with outlets continuing each predetermined distance until the wall101is spanned as shown in, for example,FIG.7A. In some embodiments, the predetermined spacing may be determined by the type of wash action needed and the type of items being washed in the sink (e.g., heavy grease may require closer nozzles). To provide fluid communication (e.g., fluidically couple) the plurality of outlets204and the sink basin102, each outlet204may define a nozzle body205that extends from the manifold body221to engage a wall101of the sink basin102to connect the respective outlets204with the sink basin102. As illustrated inFIG.7B, each nozzle body205may be formed, for example, as a cylindrical or tubular conduit through which fluid may flow between corresponding openings in the manifold body221and the wall101of the sink basin. In some embodiments, the nozzle body may be an opening at the manifold221and the wall101if the manifold is attached directly to the wall. In some embodiments, each nozzle body205may be secured to the wall101of the sink basin102via welding, via threaded nut, or via other equivalent technique.

For example, in some embodiments, the nozzle body205may define a threaded portion at a distal end opposite the manifold201and a flange positioned proximally of the threaded portion to engage an outer surface of the wall101of the sink basin102such that the threaded portion is configured to protrude through an opening in the wall101of the sink basin102to engage a threaded nut on an inner surface side of the wall101.

The present disclosure contemplates that the dimensions (e.g., length, cross-sectional size, size, and shape) of the nozzle bodies205may be any value for the intended application of the soaker sink100. In some embodiments, each of the plurality of outlets204may be adjustable (e.g., via different flow restrictors) and may define a common outlet dimension (e.g., the same internal diameter and/or cross-sectional area) or a varied outlet dimension depending upon the desired performance and washing action of the outlets. In some embodiments, the fluid flow rate of one or more outlets204may be modified by the use of flow restrictors300(e.g., inserts mountable within the outlets204to control the flow area of the outlet). In some embodiments, the nozzle bodies205may define the same dimensions as each other (e.g., the same internal diameter and/or cross-sectional area) and flow restrictors300of one or more different dimensions may be inserted into the nozzle bodies to modify the velocity, flow rate, and the like through the nozzle bodies relative to their normal state (e.g., a state without any flow restrictor). The flow restrictors300may be configured to vary the outlet dimension for selected outlets204such that at least one outlet204has a different outlet dimension than one or more other outlets. Choosing flow restrictors of different internal dimensions may be configured, for example, to balance the flow rate and/or velocity between outlets and may be used to adjust each outlet individually relative to the other outlets in concerted or individualized ways. In some embodiments, blanks may be used to completely close one or more outlets204(e.g., if higher velocity flow is desired through other outlets).

In some embodiments, the flow restrictors300may be collectively used for and configured to modify the flow rate and/or velocity of the plurality of outlets204. For example, in some embodiments, each of the outlets may include flow restrictors300to increase the net velocity of flow through all of the outlets and thus collectively increase the washing action for a given pump rate. In some embodiments, the flow restrictors300may all be the same (e.g., having a common dimension and causing the outlets to have a common outlet dimension) and collective set of flow restrictors may be chosen with a certain dimension based on the desired circulation speed, outlet velocity, and agitation in the sink. In some embodiments, the outlet dimension (e.g., the internal diameter or cross-sectional area) for each outlet204may be the same following use of a respective flow restrictor300, such as in embodiments with identical flow restrictors. In some embodiments, both the collective size and the individual size of the flow restrictors may be fine-tuned to produce an optimal wash action. For example, if greater wash agitation is needed in the entire sink, all flow restrictors300may be replaced with narrower flow restrictors even in situations where one flow restrictor is already narrower than another. In some embodiments, the outlet dimension may be measured at a narrowest portion of the outlet, including the flow restrictor, along its length between the manifold body221and the sink basin102. In some embodiments, the outlet dimension may refer to multiple parameters of the nozzle. In some embodiments, the outlet dimension may be measured in the same axial location along the outlet's length between the manifold body221and the sink basin102for each outlet to enable accurate comparison. In some embodiments, the outlet dimension may be empirically determined based on the actual flow rate through each outlet and may be classified accordingly as having a “greater” outlet dimension for all outlet shapes and assemblies having a greater net flow rate and/or a lower net velocity, and likewise as having a “lesser” outlet dimension for all outlet shapes and assemblies having a lower net flow rate and/or a higher net velocity than a given outlet. Furthermore, in some embodiments, multiple outlets204may be fluidically coupled with the sink basin102at the wall101via a common or shared nozzle body205.

As shown inFIG.7AandFIG.11, the wall101may also be angled, for example, to adjust the flow direction of the fluid output by the plurality of outlets204. By way of example, the wall101may be form a lip, flange, extension, bend, shelf, dip, recess, etc. at which the nozzle bodies205may be attached so as to direct the fluid output by the outlets204. As illustrated in the example embodiment ofFIG.7A, the wall101may be positioned such that the fluid discharged via the outlets204is at least partially directed toward a bottom surface of the sink basin102, with the outlets204being engaged with the wall within a horizontal recess formed (e.g., by bending the sheet metal) in the wall, such that fluid from the outlets may, in some embodiments, enter the sink basin within the recess. The recess in the wall101may prevent pans from blocking the outlets204and/or may facilitate the downward angle of the outlets204.

With reference toFIG.11, a side view of the interior of the soaker sink100is illustrated during an example washing operation with associated flow streamlines showing the circulation paths of the fluid leaving the outlets. These streamlines illustrate an example outlet flow path306of fluid discharged into the sink basin102by respective outlets204. As shown, plurality of outlets204may output fluid at an angle θ with respect to the horizontal (e.g., relative to the width-wise dimension (W) of the sink basin, a plane parallel to the bottom of surface of the sink basin102, or the like). In some embodiments, the angle θ may be varied based upon the dimensions of the sink basin102to optimize the circulation flow relative to the shape of the sink basin and the positioning of the outlets. The angle θ may be configured such that the outlet flow path306is directed towards the bottom surface of the sink basin102so as to cause the fluid discharged by the plurality of outlets204to be at least partially redirected by the bottom surface of the sink basin102(e.g., redirected in the counter-clockwise direction relative to the orientation ofFIG.11). Said differently, the angle θ may be such that the fluid discharged by the plurality of outlets204glances, skips, bounces, ricochets, or otherwise deflects off of the bottom surface of the sink basin102. Following this redirection, the angle θ and width (W) of the sink basin102may be such that, in some embodiments, the flow is further redirected by a front wall (e.g., a surface opposite the manifold201) of the sink basin102.

The angle θ may, in some embodiments, be determined based upon the attachment between the manifold201and the sink basin102as described above. For example, in some embodiments, each nozzle body205may be secured to the wall101of the sink basin102via welding, via threaded nut, or via other equivalent technique such that the orientation of the nozzle body defines the angle θ. For example, in some embodiments, the nozzle body and the outlet flow path306may form a 30° angle with respect to the horizontal (e.g., θ is 30°). In some embodiments, the nozzle body205may intersect the wall101at a perpendicular angle, such that the wall of the recess may be sloped perpendicular to the outlet flow path306. In some embodiments, one or more of the flow restrictors300may be manufactured at an offset angle (e.g., the internal bore defines an axis that is angled relative to the outer surface of the flow restrictor and the nozzle body, such that fluid leaving the flow restrictor is directed at a different angle than the nozzle body). Thus, when the flow restrictor is inserted into the nozzle body, the net angle of the outlet changes from the angle of the nozzle body to the angle of the offset internal bore of the flow restrictor. Each flow restrictor may be offset by a same amount, in an instance in which the outlets are collectively reoriented to improve washing action. In some embodiments, individual outlets may be offset at different angles from one or more other outlets to produce a different washing action between outlets. In some embodiments, the offset may be used to customize or calibrate the performance of the soaker sink for the customer, with the flow restrictors300being replaceable parts making the offset angle quickly configurable on site after manufacture of the soaker sink.

Although described and illustrated herein with reference to a plurality of outlets204and nozzle bodies205configured to provide a common outlet flow path306(e.g., discharge fluid from the manifold201at substantially the same angle θ), the present disclosure contemplates that the outlet flow path for each outlet204may vary based upon the intended application of the soaker sink100(e.g., one or more of the outlets may be oriented at a different angle from the others). In some instances, as described hereafter, one or more flow restrictors300may be removably coupled with one or more outlets204of a plurality of outlets so as to dynamically modify the angle θ at which the fluid discharged from the manifold201. For example, a flow restrictor300may be configured to increase or decrease the angle θ based upon the intended application of the soaker sink100(e.g., to modify or adjust the washing action within the sink basin102). In one example, the angle θ with respect to the horizontal may be between approximately 30° and 33° in order to provide an improved washing action (e.g., improve circulation within the sink basin102) for a first size sink (e.g., a sink having a first front-to-back width). In an example, the angle θ with respect to the horizontal may be between approximately 27° and 30° for a second size sink smaller than the first size sink (e.g., a sink having a lesser front-to-back width than the first front to back width). In some embodiments, the outlets may be oriented towards a location at or approximately 11 inches from the front wall of the sink basin102.

In order to modify the mass flow rate and/or velocity of the fluid discharged via the respective outlets204of the manifold201, the distance between each outlet204and each other and/or the inlet opening202may be modified and/or the cross-sectional area of each outlet204may be modified. In some embodiments, only the cross-sectional area may be modified in situ after manufacturing (e.g., via interchangeable flow restrictors300). In some embodiments, many parameters of the fluid distribution assembly and outlet assemblies may alter the mass flow rate and velocity of the fluid through the outlets. In some embodiments, an outlet dimension (e.g., cross-sectional area, diameter, etc.) may be changeable via inserting different flow restrictors while the remaining parameters of the other flow restrictors and/or fluid distribution assemblies are kept constant. The volumetric flow rate (Q) for each outlet may be determined as a product of the flow velocity (v) and the cross-sectional vector area (A) or Q=ν·A, and the total volumetric flow rate through the manifold may be determined as the sum of the respective flow rates of each outlet Q=(ν1·A1)+(ν2·A2)+(ν3·A3)+(ν4·A4)+. . . , which may also depend upon the flow rate of the pump. As such, the collective fluid flow discharged from the manifold201via the outlets204(Q), and by association the mass flow rate of the collective fluid flow across all outlets, may equal that of the fluid flow input to the manifold201from the pump, and the balance of the fluid flow between the outlets may be determined based upon the cross-sectional (A) of the respective outlets204and the respective fluid velocity (v) at each outlet204. Said differently, in order to modify the velocity (v) of fluid output by a particular outlet204to improve the washing action as described above, the cross-sectional area (e.g., an outlet dimension) for the particular outlet204may be adjusted, such as by being reduced (e.g., via use of a narrower flow restrictor) resulting in an increased velocity for the particular outlet204for a particular volumetric flow rate (Q) and, as between outlets, may also change the flow rate of the outlets. Increasing the velocity and narrowing the cross-sectional area of an outlet may reduce the mass/volumetric flow rate of one nozzle relative to the other nozzles (e.g., by somewhat decreasing the flow rate of the restricted nozzle and proportionately increasing the flow rate of the remaining nozzles). Using flow restrictors in every nozzle or replacing existing flow restrictors with narrower flow restrictors may increase the velocity of the fluid entering the tub and collectively increase agitation of the dishware while retaining the same mass flow rate. In some example embodiments, flow restrictors300having equal internal flow areas (A) may be used in each outlet204of the soaker sink. In some example embodiments, flow restrictors300having internal flow areas (A) of differing sizes may be used. In some example embodiments, the flow restrictors300may be configured to equalize the velocity of the fluid leaving each nozzle. In some embodiments, the net mass flow through all nozzles collectively (QTOT) may remain constant or substantially constant and may be determined by the net mass flow rate of the pump.

With reference toFIG.12, a top view of the interior of the soaker sink100is illustrated during an example washing operation with associated flow streamlines. These streamlines illustrate an example outlet flow path of fluid discharged into the sink basin102by respective outlets204. As shown inFIG.12, the manifold201may include, in some embodiments, ten (10) outlets204that may be evenly spaced along a length of the manifold201(e.g., equidistant from each other and/or equally spaced across the width of the sink basin). Although illustrated and described herein with reference to an example embodiment having ten (10) evenly spaced outlets204, the present disclosure contemplates that the number of outlets and the relative spacing between the outlets204and/or the inlet opening202may vary based upon the size of the soaker sink and/or the intended application or washing action of the soaker sink100. In the particular implementation ofFIG.12, the outlets204may be configured such that each of the plurality of outlets204includes a common outlet dimension (e.g., cross-sectional area, diameter, or the like). For example, the flow depicted inFIG.12was generated using identical flow restrictors having round bores. In some embodiments, one or more of the outlets may alternatively have a different outlet dimension (e.g., to balance the velocity of fluid exiting each outlet). In some embodiments, the outlet dimensions may be staggered along the length of the manifold. Such outlet dimensions may, for example, be defined by the dimensions of the flow restrictor300coupled thereto as described herein. In the embodiment illustrated inFIG.12having the same, common outlet dimensions across all outlets, the flow rate (e.g., mass flow rate and by association volumetric flow rate (Q)) increases for each subsequent outlet204along the length of the manifold201as shown in the table ofFIG.12. As the fluid flow travels from the inlet opening202along the interior of the manifold201, the fluid flow velocity within the manifold decreases due to frictional forces, shear forces, resistance to flow, etc., and the mass flow rate increases at each subsequent outlet moving away from the inlet in the depicted embodiment. Said differently, the flow velocity within the manifold201proximate the inlet opening202is greatest such that the mass and volumetric flow rate of the fluid discharged by the outlets204closer in distance to the inlet opening202is reduced (e.g., the mass flow rate of outlet10is greater than the mass flow rate of outlet1when the outlet dimensions (inclusive of flow restrictors) are the same). This effect is illustrated in the example mass flow rate value ofFIG.12.

In some embodiments, each of the plurality of outlets204may include an inner diameter, inclusive of the effect of any flow restrictors, of between and including approximately 1 inch and approximately 0.25 inches. By way of a particular example, each of the plurality of outlets204may define an inner diameter of 0.8 inches, 0.6 inches, or 0.4 inches based upon the size of the sink basin102, the output of the pump104, the intended washing action, and/or the like. In some embodiments, each of the plurality of outlets204may define the same internal diameter, and in some embodiments, one or more pairs of the plurality of outlets204may have different internal diameters (e.g., decreasing diameters between adjacent outlets). The internal diameters may include a narrowest dimension within the outlet between the manifold and the sink basin, inclusive of any flow restrictor (e.g., the inner diameter of the flow restrictor300at a narrowest point may be 1 inch to 0.25 inches). In some embodiments, the narrowest dimension of each outlet may be greater than or equal to the size of the openings on the perforated plate covering the inlet opening106to prevent clogging.

As described above and more fully hereafter with reference toFIGS.9-10, the soaker sink100may include a plurality of flow restrictors300that are removably coupled with respective outlets204in order to modify the volumetric and mass flow rate of the outlet and, by association, control the velocity of the fluid discharged via the respective outlet204. As such, in some embodiments, the plurality of flow restrictors300may be configured to modify (e.g., reduce) the outlet dimension (e.g., inner diameter, cross-sectional area, etc.) of the outlets204relative to an open bore of the nozzle body205. In some embodiments, the present disclosure contemplates that the common outlet dimension of the plurality of outlets204may refer to an instance in which each of the outlets204receive a respective flow restrictor300configured such that each of the plurality of outlets204have the same net outlet dimension, inclusive of the effect of each flow restrictor. In instances in which the nozzle bodies205define the same dimensions (e.g., diameter, length, etc.) and are identical but for their relative location on the manifold, the plurality of associated flow restrictors300may similarly comprise the same shape or configuration (e.g., each of the flow restrictors300may be substantially the same in size, shape, orientation, etc.) to cause all of the outlets to have the same common outlet dimension, or the flow restrictors300may vary between outlets to cause the outlets to have differing outlet dimensions without altering the nozzle bodies as described herein. In embodiments in which at least one outlet204includes a different outlet dimension than another outlet (e.g., at least one outlet has a larger or smaller inner diameter, cross-sectional area, etc.), the corresponding flow restrictors may be dimensioned (e.g., sized and shaped) differently to alter the outlet dimension between outlets, while the nozzle body205remains a common internal diameter between outlets (e.g., the flow restrictors may change the sizes of the outlets).

In some instances, the embodiments of the present disclosure may be configured to collectively balance the fluid flow discharged by the plurality of outlets204. For example, a first flow path207may be defined from the inlet opening202to the sink basin102via the first outlet206as shown inFIG.8. A second flow path209may be defined from the inlet opening202to the sink basin102via the second outlet208. As the fluid flow travels from the inlet opening202along the interior203of the manifold201, the fluid flow velocity decreases due to frictional forces, shear forces, resistance to flow, etc. The fluidic distance D2between the second outlet208and the inlet opening202is greater than the fluidic distance D1between the first outlet206and the inlet opening202. The structure shown and described with respect toFIG.12resulted in a greater volumetric and mass flow rate of the fluid discharged via the second outlet208(e.g., the larger fluidic distance D2) than the first outlet206(e.g., the smaller fluidic distance D1). In some embodiments, the outlet dimension (e.g., area) of each outlet may be different. In particular, the one flow path may define a narrowest cross-sectional area that is smaller than a narrowest cross-sectional area of another outlet. As used herein, the term, “narrowest cross-sectional area”, may refer to the cross-sectional area at a narrowest point along the flow path, which in some embodiments may be defined at the outlets (e.g., via flow restrictors300). In some embodiments, one or more outlets within an otherwise balanced assembly may have a different velocity for one or more specialized purposes as discussed herein (e.g., eight of ten nozzles may be configured via flow restrictor to have the same outlet velocity, while two of the ten have increased velocity via flow restrictor to generate a focused wash area).

In other embodiments, the narrowest cross-sectional area of the outlets204, the relative positioning between outlets204, and the respective distance between each outlet204and the inlet opening202may be varied to modify the flow recirculated to particular locations within the sink basin102. By way of a non-limiting example, a stand, support, rack, etc. (not shown) may be positioned within the sink basin102proximate the Nthoutlet. As such, the velocity of the fluid discharged by the Nthoutlet may be increased (e.g. a decrease in the narrowest cross-sectional area) so as to encourage or otherwise facilitate cleaning of the dishware positioned by the example stand, support, rack, or the like (not shown) proximate the Nthoutlet. In this way, the embodiments of the present disclosure may operate to modify the flow rate of fluid outlet204by the manifold201at any location or position within the sink basin102. In some embodiments, one or more outlets204may have their outlet dimension adjusted for such a particular purpose while leaving the remaining outlets configured with the same outlet dimension or another predetermined outlet relationship. In some embodiments, the user may replace one or more inserts between cycles based on the particular load being washed or upon choosing a particular purpose of the washer or sub-portion of the washer (e.g., washing a certain category of item requiring a particular wash action).

In some embodiments, the flow rate through the outlets204may be controlled in a variety of additional configurations depending upon the predetermined flow pattern desired within the soaker sink. For example, in some embodiments as described above, a uniform mass flow pattern may be desired, such that each outlet may be configured (e.g., via flow restrictors) to output the same or substantially the same flow rate (e.g., volumetric/mass flow rate) by offsetting the differences in flow caused by the relative positioning of the inlet opening202and the outlets204. In some embodiments, areas of higher or lower recirculation intensity may be desired within the wash basin102, such that a greater flow rate may be directed to one or more sub-portions of the wash basin than to another portion or portions. In some embodiments, a uniform flow velocity may be desired, such that each outlet may be configured (e.g., via flow restrictors) to output the same or substantially the same velocity by offsetting the differences in flow caused by the relative positioning of the inlet opening202and the outlets204.

With reference toFIGS.9-10, a more detailed view of the flow restrictors300is shown. As described herein, in order to adjustably modify the flow rate and velocity of at least one outlet204, the fluid distribution assembly200may include one or more flow restrictors300that are removably coupled with one or more outlets204of a plurality of outlets. In some embodiments, the flow restrictor300may define a body having a shape that is complementary to the shape (e.g., at least the cross-sectional shape) of the nozzle body205of the associated outlet204such that the flow restrictor300may be removable secured within the nozzle body205. By way of a particular example, the flow restrictor300may be formed as a cylindrical sleeve configured to be inserted within the nozzle body205, wherein the outer shape of the flow restrictor is complementary to the inner shape of the nozzle body205. In some embodiments, a plurality of flow restrictors300may be used. The plurality of flow restrictors300may be universally fit to a common outlet204shape (e.g., a common inner surface shape of the nozzle body205in embodiments with a nozzle body), such that the flow restrictors may be configured to be interchangeably inserted into multiple outlets depending upon the desired configuration.

As described hereafter with reference toFIG.10, the flow restrictor(s)300may operate to reduce the cross-sectional area of one or more outlets204removably coupled with the respective flow restrictor(s)300in order to modify a flow rate and associated velocity of the fluid discharged via the respective outlet204, with a narrower outlet generally having less mass flow and a higher velocity than a wider outlet with all else being held equal. As an example, the first outlet206is illustrated inFIG.9engaged with an associated flow restrictor300, and the second outlet208is illustrated prior to receipt of an associated flow restrictor300. Although illustrated and described herein with reference to a flow restrictor300having a cylindrical shape that complements the cylindrical shape of a corresponding nozzle body205, the present disclosure contemplates that the flow restrictor300may have any size, shape, cross-sectional area, etc. so as to reduce the cross-sectional area of an associated outlet204. For example,FIG.10shows a flow restrictor300in cross-sectional view having a tapered upstream section and a generally cylindrical downstream section to smoothly restrict the flow from the wider nozzle body205cross-sectional area to the narrower flow restrictor cross-sectional area. As another example,FIG.13, described below, shows a V-shaped nozzle configured to create a horizontal fan-shaped spray pattern. In some embodiments, flow restrictors may have different narrowest internal diameters and may otherwise be identical to each other.

In order to removably secure the flow restrictor300within the respective nozzle body205, the flow distribution assembly200may include one or more fasteners. By way of example, the fluid distribution assembly200may include a leaf spring302or equivalent mechanism that is, once the flow restrictor300is positioned sufficient within the nozzle body205, configured to be inserted into the nozzle body205and located within a groove (e.g., groove212inFIG.10) of the nozzle body205. In this way, the leaf spring302may operate to removably secure the flow restrictor300within the nozzle body205such that the flow restrictor300may be removed and/or replaced to modify the flow rate and associated velocity of the fluid discharged via the outlet204while also preventing the flow restrictor from inadvertently being expelled from the nozzle. The present disclosure contemplates that any mechanism for removably coupling the flow restrictor300with the outlet204may be used.

With reference to the cross-sectional view ofFIG.10, the flow restrictor300may operate to reduce the cross-sectional area of the associated outlet204. By way of example, an internal bore of the nozzle body205may define a first cross-sectional area210at its narrowest longitudinal point, and an internal bore of the flow restrictor300may define a second cross-sectional area304at its narrowest longitudinal point. The second cross-sectional area may be smaller than the first cross-sectional area210such that securing the flow restrictor300within the nozzle body205reduces the flow rate and increases the velocity of the outlet204with all else being held equal. In some embodiments, the inner cross-sectional area of the nozzle body205may be constant. As described above, the collective fluid flow discharged from the manifold201via the outlets204(Q) may be determined based upon the net cross-sectional (A) of the respective outlets204and the respective fluid velocity (v) at the outlet204. This net fluid flow may be determined also by the flow rate of the pump, such that the cross-sectional area of each outlet204may be determined to affect the incremental flow rate of each outlet (e.g., for N outlets and a pump flow rate of Q′, an evenly balanced set of outlets would produce a flow rate of Q′/N for each nozzle).

As the fluid flow travels from the inlet opening202along the interior203of the manifold201, the fluid flow velocity decreases due to frictional forces, shear forces, resistance to flow, etc. As such, the volumetric and mass flow rate and the velocity at each subsequent outlet204is increased as shown inFIG.12. In some embodiments, the discharge of fluid from the interior of the manifold201may be balanced such that, for example, the velocity or flow rate (e.g., measured as mass or volumetric flow rate) associated with each outlet204is substantially uniform.

In other embodiments, however, the flow restrictors300may be used to dynamically modify the narrowest cross-sectional area of the outlets204so as to modify the flow recirculated to particular locations within the sink basin102. Similar to the embodiments described with reference toFIGS.7A-7B, a stand, support, rack, etc. (not shown) may be positioned within the sink basin102proximate the Nthoutlet204. As such, the velocity of the fluid discharged by the Nthoutlet204may be increased by decreasing the size of the cross-sectional area or inner diameter of the outlet204, such as by replacing the flow restrictor300with another flow restrictor300having a smaller cross-sectional area at its narrowest longitudinal point so as to encourage or otherwise facilitate cleaning of the dishware positioned by the example stand, support, rack, or the like (not shown) proximate the Nthoutlet204. In this way, the embodiments of the present disclosure may operate to allow for dynamic modification of the flow rate of any outlet204of the manifold201so as to modify the recirculation of fluid within the sink basin102. As such, the use of flow restrictors300may operate to modify, adjust, or fine tune the total washing action (e.g., vary the fluid output velocity, volumetric flow rate, mass flow rate, etc.) depending on the size of the sink basin102, the pressure or output flow rate from the pump104, the number of nozzles204, the type of dishes being washed, customer preference, wash time required, and/or the like.

In some embodiments, a separate fluid distribution assembly, or portion thereof, may be sold to replace an existing fluid distribution assembly (e.g., to add the flow restriction capabilities via retrofit to an existing soaker sink). In some embodiments, one or more (e.g., a set) flow restrictors300may be sold separately to modify the flow within a soaker sink basin to allow the user to fine tune the wash performance. For example, two or more predetermined recirculation flow patterns may be enabled by swapping sets of flow restrictors or otherwise replacing the flow restrictors at each nozzle. In some embodiments, an intensified wash zone may be created by inserting narrower flow restrictors in a subset of the nozzles, thus increasing the velocity at those nozzles.

In some embodiments, as shown inFIG.13, the outlets204and/or the flow restrictors300may define a V-shaped flow restrictor400configured to facilitate or otherwise direct the discharge of fluid from the manifold201. The V-shaped flow restrictor400may, as shown, define a notch, indentation, depression, cavity, channel, trough, or other such flow feature402configured to modify the output flow of an outlet204coupled with the V-shaped flow restrictor400. In some embodiments, as shown inFIG.13, the flow feature402may define a V-shaped notch configured to increase the spread of the fluid discharged by the outlet204(e.g., a V-shaped nozzle configuration). In particular, the V-shaped flow restrictor400may define a notch402(e.g. a flow feature) that is oriented horizontally (e.g., parallel with respect to the bottom surface of the sink basin102) so as to increase the horizontal spread of the fluid discharged by the outlet204. Said differently, the notch402of the V-shaped flow restrictor400may cause the fluid discharged by the outlet204associated with the V-shaped flow restrictor400to fan outwardly in a horizontal direction (e.g., parallel with respect to the bottom surface of the sink basin102) so as to provide a wider flow path and increase and improve circulation of the washing action within the sink basin102across the full width of the basin. The present disclosure contemplates that, in some embodiments, the outlets204may comprise the V-shaped flow restrictor400while, in other embodiments, other versions of the flow restrictor300may be used. In some embodiments, fewer outlets may be needed with V-shaped flow restrictors400than with cylindrical/circular bored flow restrictors because of the wider flow of the V-shaped outlets. Although illustrated with a V-shaped flow feature402, the present disclosure contemplates that the flow restrictors may include a feature of any type, dimension, orientation, etc. based upon the intended washing action of the soaker sink100.

Methods associated with the soaker sinks, flow distribution assemblies, and various components, assemblies, and devices disclosed herein may also be provided. A method of adjusting the flow rate through one or more nozzles of the flow distribution assembly may include inserting a flow restrictor into a nozzle body from within the soaker sink and securing the flow restrictor in place (e.g., via engaging a leaf spring302with a groove212in the nozzle body205as shown inFIG.10). In some embodiments, the method may first include removing an existing flow restrictor by disconnecting the fastener and removing the flow restrictor (e.g., via the sink basin) in a reverse operation of the insertion process.

In some embodiments, a method of using various embodiments of the soaker sink described herein may be provided. The method may include filling the sink basin with fluid (e.g., fresh water with or without detergent additives), adding wash items to be washed, and initiating operation of the pump to recirculate the fluid from the inlet opening106to the fluid distribution assembly200and back into the sink basin. In various embodiments discussed herein, the sink basin102may be filled sufficiently high with fluid to submerge the nozzles204during recirculation.
