[0001] Cross Reference to Related Applications

[0002] This application claims the benefit of and priority to U.S. Patent Application No. 63 / 047,108, filed July 1, 2020, the entire disclosure of which is incorporated by reference herein. BACKGROUND

[0003] The present disclosure relates generally to the field of shower systems, and more particularly, to the field of water recirculating shower systems.

[0004] Existing showerheads that can be installed in private settings (e.g., homes) or public settings (e.g., gyms, hotels) can consume a large amount of water each time they are used. In some cases, it can be desirable to reduce the amount of water consumed and waste produced each time a shower is taken, which can advantageously promote water conservation and pollution reduction.

[0005] Accordingly, it would be advantageous to provide an improved shower system that is capable of recovering and recirculating dispensed water to reduce pollution and consumption of clean, fresh water. SUMMARY

[0006] One embodiment of the present disclosure relates to a recirculating shower system including a first shower outlet and a second shower outlet. The recirculating shower system can include a fresh water conduit fluidly coupled to the first shower outlet and a recirculating fluid conduit fluidly coupled to the second shower outlet. The fresh water conduit and the recirculating fluid conduit can be arranged such that warmer fresh water flowing through the fresh water conduit can heat cooler recirculating fluid flowing through the recirculating fluid conduit.

[0007] One embodiment of the present disclosure relates to a recirculating shower system including a first fluid chamber fluidly coupled to a first shower outlet and a second fluid chamber fluidly coupled to a second shower outlet. The recirculating shower system can include a container operably coupled to the first shower outlet and the second shower outlet. The container can be configured to collect fluid dispensed from the first shower outlet and the second shower outlet. The recirculating shower system can include a fresh fluid conduit fluidly coupled to the second fluid chamber and configured to provide fresh fluid to the second fluid chamber. The first shower outlet can be configured to dispense the collected fluid, and the second shower outlet can be configured to dispense the fresh fluid. The first fluid chamber can be separate from the second fluid chamber.

[0008] One embodiment of the present disclosure relates to a recirculating shower system including a showerhead comprising a plurality of outlets. The recirculating shower system can include a container operably coupled to the showerhead and configured to collect fluid dispensed from the plurality of outlets. The recirculating shower system can include a first fluid conduit fluidically coupled to a first outlet of the plurality of outlets and a second fluid conduit fluidically coupled to the container and a second outlet of the plurality of outlets. The recirculating shower system can include a heat exchanger. A first fluid source can be configured to provide fresh fluid to the first outlet and a second fluid source can be configured to provide recirculated fluid to the second outlet. The heat exchanger can be configured to exchange heat between the relatively hot fresh fluid from the first fluid conduit and the relatively cold recirculated fluid from the second fluid conduit.

[0033] Before turning to the figures, which illustrate certain example embodiments in detail, it should be understood that the disclosure is not limited to the details or methodology set forth in the detailed description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of describing only specific embodiments and is not intended to be limiting.

[0034] Referring generally to the figures, in various embodiments, a recirculating shower system includes at least one shower outlet, a shower column fluidly coupled to the shower outlet, a shower floor, and a soap and debris management assembly. The shower column can be configured to house a water recirculation device within a shower space (e.g., a corner). In various embodiments, the shower column can facilitate access to shower control components for ease of installation and / or repair. The shower column can also be designed to serve as an aesthetically pleasing covering to conceal potentially unattractive shower control components. In various embodiments, the shower control components can include, but are not limited to, one or more pumps, motors, filters, DTV indicators, etc. In various embodiments, the shower column can be detachably coupled to an area within the shower via one or more hinges or latches.

[0035] In various embodiments, the shower floor (“receiver”) can be in operative communication with the shower column and configured to collect water dispensed from a water source (e.g., a showerhead). In various embodiments, the recirculating shower system can include a central control mechanism to facilitate operatively connecting the shower floor with a sump, shower column, and / or other shower components. In various embodiments, the shower floor can be customizable.

[0036] In various embodiments, the recirculating shower system can be configured to dispense fluid collected in the shower floor at a predetermined rate. In various embodiments, the recirculating shower system can be configured to dispense fluid collected in the shower floor such that the water in the shower floor is completely replaced within a specified amount of time (e.g., 10 seconds, 20 seconds, 30 seconds, etc.).

[0037] In various embodiments, the recirculating shower system can include a soap and debris management assembly. The soap and debris management assembly can be configured to monitor and / or remove soap and debris from water collected from the shower floor, facilitate treatment of the collected water, and enable recirculation of the collected and treated water. In various embodiments, the removal of soap and / or debris can be based at least in part on one or more characteristics associated with water flow and overflow drain points from a top surface of the shower floor to the recirculating sump. In various embodiments, the one or more characteristics can include, but are not limited to, soap content (e.g., amount of suds generation, etc.) and debris (e.g., hair, dirt, etc.). In various embodiments, the soap and debris removal assembly can be configured to determine an amount of suds and / or debris generation, determine how to minimize suds and / or debris, and / or how to remove suds and / or debris. In various embodiments, the recirculating shower system can include a large peripheral that directs soap water in a thin layer across the edge on the top surface of the shower floor and into a hidden water treatment channel that subsequently directs the soap water to an overflow sump and / or a recovery pump sump. The large peripheral causes a thin flow layer such that suds and / or air bubbles can be carried out of view of the shower user and into the overflow sump. In various embodiments, the shower floor includes a cover (i.e., user standing area) that can be angled to complement the hidden water treatment channel.

[0038] In various embodiments, the recirculating shower system can include an intermediate pump integrated between the shower floor and the shower column. In various embodiments, the intermediate pump can be a standard pump, or the intermediate pump can be a custom pump specifically configured and customized for a particular system. In various embodiments, the intermediate pump can initiate a recovery operation to facilitate recirculation of collected water. In various embodiments, the intermediate pump can initiate the recovery operation at the bottom of the shower sump. In various embodiments, the intermediate pump can remain accessible when in use to facilitate installation and / or maintenance.

[0039] In various embodiments, the recirculating shower system can include a water control system. The water control system can facilitate automatic control of water-related measurements with water-related indicators. In various embodiments, the control system can provide an automatic response to manage and maintain water cleanliness based on measured water contamination levels and / or water clarity. In various embodiments, the automatic response can be based on a threshold of water contamination and / or water clarity. In some embodiments, the threshold can be user-defined, manufacturer-defined, or a combination thereof. In various embodiments, the control system can be configured to measure turbidity of the water. In some embodiments, the control system can be operably coupled to a water turbidity sensor (e.g., an inline sensor, etc.) to facilitate monitoring of the water. In some embodiments, the control system can be configured to remove dirty water from the recirculating shower system based on water-related measurements or samples (e.g., water turbidity). In various embodiments, the control system can facilitate measurement and mitigation of various human-borne contaminants (e.g., soap, gel, etc.). In various embodiments, the control system can facilitate acid testing and / or treatment of the water within the recirculating shower system. In some embodiments, the control system can include one or more drain and / or refresh cycles that facilitate enhanced water circulation and, thus, enhanced user experience by reducing the need for users to self-monitor the condition of the dispensed water during use. In various embodiments, the control system and operation can be customized based on user and / or manufacturer preferences.

[0040] In various embodiments, the recirculating shower system can include an ozone generator that facilitates disinfection of the recirculating shower system. In various embodiments, the ozone generator can be coupled to the recirculating shower system such that fresh water (e.g., from a cold water manifold, a mixing valve, etc.) can be injected with ozone to facilitate disinfection of bacteria, viruses, or other contaminants in the water.

[0041] In various embodiments, the recirculating shower system can include a self-heating unit or can have self-heating capabilities associated with one or more components. In various embodiments, one or more heaters can be in fluid communication with water collected by the overflow sump and / or the recovery pump sump. In other embodiments, the recirculating shower system can include a controllable mixer for controlling the temperature of collected and treated water dispensed from a water source (e.g., a showerhead). In some embodiments, the controllable mixer and / or one or more heaters can operate based on one or more predetermined temperature settings. In various embodiments, the predetermined temperature settings can be based on user-defined temperature setpoints, manufacturer-defined setpoints, or combinations thereof. In various embodiments, the recirculating shower system can implement a self-heating function (e.g., via one or more heaters and / or a controllable mixer) during a pre-shower warm-up period. In various embodiments, the pre-shower warm-up can cause the recirculating shower to self-heat until at least one of a time setpoint and a temperature setpoint is reached. In various embodiments, the recirculating shower can be configured to operate in response to a manual command and / or an automatic command (e.g., AI).

[0042] In various embodiments, the recirculating shower system can include a plurality of shower outlets each in fluid communication (e.g., via a conduit) with a plurality of fluid sources. In various embodiments, the recirculating shower system can include two or more shower heads for dispensing the plurality of fluid sources (e.g., via a conduit). In other embodiments, the recirculating shower system can include one shower head comprising a plurality of outlet sub-devices each in fluid communication (e.g., via a conduit) with a plurality of fluid sources. In various embodiments, the plurality of outlets can be configured such that fluid from the plurality of fluid sources (e.g., via a conduit) does not mix (e.g., merge, contact, etc.) upstream of the plurality of outlets (e.g., prior to being dispensed from the shower head). In these embodiments, the plurality of fluid sources can mix in the air of the recirculating shower system (e.g., while being dispensed to the user). In other embodiments, one or more fluids from the plurality of fluid sources (e.g., via a conduit) can mix (merge, contact, etc.) upstream of the plurality of outlets (e.g., prior to being dispensed from the shower head). In various embodiments, the recirculating shower system can include two or more of the plurality of fluid sources (e.g., via a conduit) configured such that the fluid sources form a heat exchanger relative to one another at a location upstream of the shower head. By way of example, two fluid sources (e.g., plumbing, conduits) can be configured such that a first fluid source (e.g., conduit, pipe, etc.) is surrounded by a second fluid source (e.g., conduit, pipe, etc.) and a first fluid of the first fluid source flows in an opposite direction to a second fluid of the second fluid source. By way of example, two fluid sources (e.g., fluids within a plumbing, conduit system) can be configured such that a first fluid source (e.g., conduit, pipe, etc.) is surrounded by a second fluid source (e.g., conduit, pipe, etc.) and a first fluid of the first fluid source flows in a parallel direction to a second fluid of the second fluid source. Thus, the first fluid conduit and the second fluid conduit can be configured to exchange heat.

[0043] In various embodiments, the recirculating shower system can include one or more mode controllers (e.g., knobs, buttons, switches, etc.) configured for a user to switch between a first operating mode, a second operating mode, or a third operating mode. In these embodiments, the first operating mode can include the plurality of outlets dispensing only a first fluid, the second operating mode can include the plurality of outlets dispensing only a second fluid, and the third operating mode can include the plurality of outlets dispensing a combination of the first fluid and the second fluid.

[0044] In various embodiments, the self-heating functionality can include managing and extracting cold water in the supply line (fluidically coupled to the controllable mixer). In various embodiments, the recirculating shower system can be configured to automatically purge cold and / or warm water in the water recirculation loop. The automatic purging allows the shower outlet or water supply (e.g., overhead shower, handheld shower, body jets, etc.) to reach the correct temperature (either pre-determined by the user or based on manufacturer settings) before the user steps into the shower space. Since the cold / warm water is purged from the recirculation loop ahead of the start of the shower, water waste is reduced as water is not unnecessarily dispensed from the shower outlet while the water is being heated. In various embodiments, the self-heating functionality can be determined based on one or more pre-determined options or options provided by a customizable user interface (e.g., touch screen).

[0045] In various embodiments, the recirculating shower system can be configured for retrofitting into an existing shower space. In various embodiments, the recirculating shower system can facilitate the collection, treatment, and recirculation of water in a traditional, single shower space (e.g., in a home, hotel, etc.). In various other embodiments, the recirculating shower system can be suitable for use in larger multiple shower spaces (e.g., in a gym, locker room, dorm, etc.). In various embodiments, the recirculating shower system can include or be fluidically coupled to a handheld shower, overhead shower, and / or body jets. In various embodiments, the recirculating shower system can be configured such that all included components are structurally integrated onto one base.

[0046] In various embodiments, the recirculating shower system can include one or more bacteria control systems. Since the recirculating shower system extracts used water from a shower catch basin (e.g., overflow catch basin and / or recovery catch basin), there is a potential for bacterial growth within the recirculating shower system and / or its associated components. Accordingly, in various embodiments, the recirculating shower system can include a chemical dosing unit that facilitates bacteria control. In some embodiments, the chemical dosing unit can facilitate periodic cleaning of the recirculating shower system with an antimicrobial agent. In various embodiments, the recirculating shower system can be configured to accommodate an existing chemical dosing system with an existing antimicrobial agent (e.g., SQ53 provided by JVS). In various embodiments, the bacteria control system can be configured to treat interior surfaces and components of the recirculating shower system. In various embodiments, the bacteria control system can include one or more filter cartridges. In some embodiments, the one or more filter cartridges can include silver-plated filters that enhance antimicrobial functionality. In other embodiments, the bacteria control system can be configured to introduce a chemical agent (e.g., antimicrobial agent, fungicide) into a shower space (e.g., shower stall) through a spray head.

[0047] In various embodiments, the recirculating shower system can include one or more components that facilitate drainage. In some embodiments, the recirculating shower system can be configured to completely drain any used water in the shower floor once the recirculating shower system is stopped (e.g., water is turned off, pump is turned off, etc.). In various embodiments, the recirculating shower system can be operated and / or controlled by software and / or control algorithms (e.g., water clarity control, etc.).

[0048] Turning now to the drawings and referring in particular to Figure 1 , a schematic view of a recirculating shower system is shown in accordance with example embodiments. As Figure 1 shown, the recirculating shower system 100 includes a shower outlet 101 for dispensing water within a shower space (e.g., a shower stall), a shower column 105 for housing a recirculating device 107 within the shower space, and a shower floor 110 for collecting used water within the shower space. The recirculating shower system 100 can also include one or more sumps, including but not limited to an overflow sump 120 and a recovery sump 125. In various embodiments, the overflow sump 120 and the recovery sump 125 can be the same sump. In various embodiments, the recirculating shower system 100 can include a separate recirculating sump fluidly coupled to the overflow sump 120 and / or the recovery sump 125. In various embodiments, the overflow sump 120 is disposed below the shower floor 110 and collects used water directed out of the shower floor 110. In various embodiments, the used water is directed out of the shower floor 110 via a periphery that causes the water to flow in a thin layer across a top surface of the shower floor 110 and into the overflow sump 120 and / or the recovery sump 125.

[0049] As Figure 1As shown, the shower floor 110 can also include a soap and debris management assembly 115 configured to facilitate controlling and managing human-carried contaminants including soap and debris that can be generated or introduced (directly or inadvertently) by a user within the shower space. In various embodiments, the soap and debris management assembly 115 can be configured to determine the amount of soap (e.g., suds) generated or present and determine how to minimize and / or effectively remove it. The soap and debris management assembly can implement one or more chemical and / or mechanical water treatments including, but not limited to, acid treatment, antibacterial treatment, filtration. The shower floor 110 can also include a channel through which collected water can be directed to the overflow sump 120 and / or the recovery sump 125. In various embodiments, the shower floor 110 can include special topography such as various angles, slopes, and / or contours to facilitate directing collected water away from the shower floor 110. The recirculating shower system 100 can also include a recovery pump 130 to pump collected water from at least one of the overflow sump 120 and the recovery sump 125 to the recirculating device 107.

[0050] As Figure 1As shown, the shower column 105 may include at least one motor 135 configured to drive at least one of the recovery pump 130 and / or intermediate pump 145 (to pump water through the recirculation device 107). The shower column 105 may also include one or more filters 140 capable of removing various contaminants from the recirculated water. As shown, the recirculation shower system 100 may also include a control system 155 configured to manage and control operations related to the recirculation of water distributed and collected within the shower space. In various embodiments, the control system 155 may be operatively coupled to one or more heaters 160, mixers 165, and / or sensors 170. In various embodiments, one or more heaters 160 may be located within the shower column 105 or separate from the shower column (but operatively coupled to the shower column). One or more heaters 160 may help heat water pumped from the overflow collection tank 120 and / or the return collection tank 125 for final output through the shower outlet 101. The mixer 165 can be controlled by the control system 155 and can help regulate the temperature of the recirculated water flowing through the recirculation shower system 100. In various embodiments, the control system 155 can be configured to enable the recirculation shower system 100 to perform self-heating operation, wherein at least one of the intermediate pump 145 and the recovery pump 130 can purify cold / warm water from within the recirculation unit 107 and initiate heating of the recirculated water before dispensing water through the shower outlet 101. In various embodiments, the control system 155 can control the operation within the recirculation shower system 100 based on one or more inputs from one or more communicatively linked sensors 170, which can be configured to detect water turbidity, water contamination levels, water temperature, or any other relevant indicators related to the water flow within the recirculation shower system 100.

[0051] The recirculating shower system 100 may also include a bacteria control system 175, which may include one or more chemical dosing units to facilitate cleaning surfaces and components within the recirculating shower system 100. In various embodiments, the bacteria control system 175 may include one or more antimicrobial agents, fungicides, and / or other chemical agents to enable cleaning of the recirculating shower system 100.

[0052] Finally, as Figure 1 As shown, the recirculating shower system 100 may include a user interface 180 operatively connected to the shower column 105, the control system 155, and / or the bacteria control system 175. The user interface 180 can set operating thresholds (e.g., temperature setpoint, water flow range, etc.) within the recirculating shower system 100.

[0053] Figure 2A perspective view of a recirculating shower system 100 is shown in accordance with an example embodiment. As shown, the recirculating shower system 100 can be disposed within a shower space and include a shower outlet 101 (e.g., a showerhead, a handheld output, a nozzle, etc.), a shower column 105, and a fluidly coupled shower floor 110. As shown, the shower column 105 can be mounted within a corner or area of the shower space that can be configured to house various components related to the control of the recirculating shower system 100 (e.g., a recirculation device 107, a motor 135, a filter 140, an intermediate pump 145, etc.). As shown, the shower column 105 can also facilitate access to additional controls 182 associated with the recirculating shower system, which can include, but are not limited to, knobs and / or interfaces that facilitate changing the water temperature. According to another example embodiment, the additional controls 182 can include a function that provides a user of the shower the ability to turn the shower recirculation function on or off (e.g., toggle between a showering experience that uses only fresh water and a showering experience that uses both fresh water and recirculated water). Figure 2

[0054] As shown, the shower floor 110 includes a soap and debris management assembly 115. In various embodiments, the soap and debris management assembly 115 can include one or more channels disposed within the shower floor. As shown, the channels of the soap and debris management assembly 115 are disposed substantially along the perimeter of the shower floor 110 and around a standing area 184 upon which a user can stand while using the recirculating shower system 100. Figure 2

[0055] Figure 3 A top view of the recirculating shower system 100 is shown in accordance with an example embodiment. As shown, the shower column 105 can be mounted within the shower space substantially perpendicular to the surface of the shower floor 110. As previously described, the shower column 105 is configured to house the water recirculation device 107, as well as other components. To facilitate access to these components, the shower column 105 can be flexibly and / or removably coupled to the shower space. As shown, the shower column 105 can be coupled to a portion of the shower space via a coupler 188 (e.g., a latch, a snap, etc.). The shower column 105 can then be rotated in a direction 186 such that access to one or more components housed within the shower column 105 in an access area 190, such as the recirculation device 107, is enabled. In various other embodiments, the shower column 105 can be removed in its entirety.

[0056] Figure 4 ​​A top view of the recirculating shower system 100 is shown proximate to the shower floor 110. As shown, the shower floor includes one or more channels within the soap and debris management assembly 115 that can be disposed along the perimeter of the shower floor 110 and around the standing area 184. The shower floor 110 can also include a central channel 192 in fluid communication with the channels of the soap and debris management assembly 115. As shown, water collected within the shower floor 110 within the soap and debris management assembly 115 can flow through the central channel 192 and to the sump and valve assembly 195. The sump and valve assembly 195 can facilitate the delivery of water for subsequent recirculation, drainage, or further collection within the shower floor 110. Water flowing through the central channel 192 can flow into the sump 196 that collects water and directs the water to the rotary valve 198. In various embodiments, the rotary valve 198 can be manually and / or remotely controlled (e.g., via software). The rotary valve 198 can be fluidly connected to the drain 194 and the pump feed chamber 200.

[0057] Although Figures 2 to 4 A shower floor 110 having a rectangular shape is shown, the shower floor 110 can have any polygonal shape. Figure 5 A shower floor 110 having various other shapes (e.g., circular, semi-circular or partial circular, elliptical, etc.) is shown in accordance with various other example embodiments.

[0058] Figure 6 A perspective view of the sump and valve assembly 195 disposed within the shower floor 110 is shown in accordance with example embodiments. As shown, the sump and valve assembly 195 includes a sump 196 configured to collect water at an inlet 203, where the collected water is received from the central channel 192 and the channels of the soap and debris management system 115. The water collected within the sump 196 is retained in a backwater sump 206 and controllably directed away from the sump 196 based on operation of the fluidly coupled rotary valve 198. The rotary valve 198 can be controlled to facilitate water flow through one or more ports 209, each of which can direct water away from the sump 196 along one or more flow paths. In various embodiments, the rotary valve 198 can be configured to have three stations: a first station to direct water for subsequent recirculation, a second station to direct water to the drain 194, and a third station to direct water for subsequent cleaning (e.g., via the filter 140, the bacteria control system 175, and / or another treatment system contained within the recirculating shower system 100).

[0059] Figure 7 A top view of the sump and valve assembly 195 is shown in accordance with example embodiments. Figure 7A first water flow path, a second water flow path, and a third water flow path are illustrated corresponding to each of the first, second, and third stations of the rotary valve 198, respectively. As shown, the first flow path 221 directs collected water to the pump inlet 212, where the water can be pumped (e.g., via the intermediate pump 145, the recovery pump 130, and / or another pump within the recirculating shower system 100) for subsequent recirculation through the recirculating shower system 100 and redistribution through the shower outlet 101. The second flow path 215 can direct collected water to the drain 194, where the water can be drained and removed from the recirculating shower system 100. The third flow path 218 can direct collected water to one or more water treatment systems or components included within the recirculating shower system 100, including but not limited to the soap and debris management assembly 115, the bacteria control system 175, the filter 140, an acid test assembly, etc. In various embodiments, the station of the rotary valve 198 and the subsequent determined water path can be based on a measured characteristic associated with the collected water (e.g., water turbidity, water acidity, water soap content, water contaminant content, etc.).

[0060] Figure 8 A flowchart illustrating a method 300 according to example embodiments is shown, including various operations performed by the recirculating shower system 100. As shown, clean water can be output from the shower outlet 101 for use by a user within the shower space in operation 305. The water used by the user can be collected within the shower floor 110 and subsequently directed (e.g., via one or more channels) to the sump 196 and the catch basin and valve assembly 195 in operation 315. The used and collected water can be treated and / or filtered by the soap and debris management assembly 115 and / or the filter 140 to remove contaminants based on the station of the rotary valve 198 in operation 320. The water is pumped (e.g., via the intermediate pump 145 and / or the recovery pump 130) and recirculated through the recirculation device 107 (in the shower column 105) and is ready to be redistributed through the shower outlet 101 in operation 325. In various embodiments, the control system 155 can initiate a self-heating operation that causes cold / warm water to be pumped (e.g., via the intermediate pump 145) through a recirculation line (e.g., within the recirculation device 107) in operation 330. The new recirculated water is then heated (e.g., via the heater 160) in operation 335 prior to the user operating the recirculating shower system 100. In various embodiments, the bacteria control system 175 can initiate a cleaning of surfaces and components within the recirculating shower system 100 after a predetermined amount of time or water recirculation cycle, or after a predetermined number of uses by the user.

[0061] Figure 9A perspective view of a recirculating shower system 400 according to an exemplary embodiment is shown. As shown, the recirculating shower system 400 may include a shower head 500 fluidly connected to a recirculating fluid conduit 425 and a fresh water fluid conduit 420. In various embodiments, the recirculating shower system 400 may include a shower wall 410 (e.g., a panel, barrier, etc.). The shower wall 410 may be installed in a corner or area of ​​the shower space and may be configured to accommodate various components associated with the recirculating shower system 400 (e.g., the recirculating fluid conduit 425, the fresh water conduit 420, controls, etc.). Figure 9 As shown, the recirculating shower system 400 may include a container 415 (e.g., a basin, bathtub, reservoir, etc.) for collecting fluid from the shower head 500. In various embodiments, the container 415 may be operatively coupled to the shower head 500 such that fluid dispensed from the shower head 500 is collected in the container 415 and discharged through a drain outlet 430. In various embodiments, the drain outlet 430 may be flush with the container 415. In various other embodiments, the drain outlet 430 may be positioned on top of or below the container 415. In various embodiments, the drain outlet 430 may include one or more functional elements to prevent fluid from clogging the drain outlet 430. For example, the drain outlet 430 may include a cap to prevent a user from clogging the drain outlet 430 with their foot. In other embodiments, the size of the drain outlet 430 may be determined to prevent a user from clogging the drain outlet 430 (e.g., larger than the average width of a human foot).

[0062] Figure 10 A side view of a recirculating shower system 400 according to an exemplary embodiment is shown. Figure 10 As shown, the fresh water conduit 420 can be connected to one or more mixers 435. In various embodiments, the mixer 435 can be configured to receive hot water from a hot water fluid source (e.g., from a water manifold) and cold water from a cold water fluid source (e.g., from a water manifold). The mixer 435 can be configured to mix hot and cold water to regulate the temperature of the fluid exiting through the shower head 500. In various embodiments, the mixer 435 can be configured to adjust the temperature based on user input (e.g., via a knob, handle, user interface 180, etc.). In various embodiments, the mixer 435 can be configured to adjust the temperature based on one or more temperature sensors, as discussed in more detail below. In various other embodiments, the recirculating shower system 400 may not include the mixer 435, such that the shower head 500 receives fluid directly from the water manifold system.

[0063] like Figure 10As shown, the recirculation shower system 400 may include a recirculation pump assembly 600 operatively coupled to a drain outlet 430. As discussed in more detail below, in various embodiments, the recirculation pump assembly 600 may be configured to receive fluid collected within a container 415 via the drain outlet 430. In various embodiments, the recirculation pump assembly 600 may be configured to pump the collected fluid from the drain outlet 430 and back to the shower head 500. For example, as... Figure 10 As shown, the recirculation pump assembly 600 can be operatively connected to the recirculation fluid conduit 425 so that the collected fluid received from the drain outlet 430 can be recirculated back to the shower head 500.

[0064] like Figure 10 As shown, the recirculating shower system 400 may include a portion configured as a heat exchanger 440. In various embodiments, the heat exchanger 440 includes an outer fluid conduit or conduit surrounding an inner fluid conduit or conduit. In various embodiments, a portion of the fresh water conduit 420 (in...) Figure 11 The outer pipe (shown as 450) may surround (e.g., encircle, receive, etc.) a portion of the recirculating fluid conduit 425, as discussed in more detail below. Warmer water flowing through the fresh water conduit 420 can then be used to heat colder water flowing through the recirculating fluid conduit 425. It should be noted that while the embodiments shown herein illustrate a fresh water conduit having a portion of the recirculating fluid conduit therein, the reverse may also be true according to other exemplary embodiments (e.g., the recirculating fluid conduit may contain a portion of the fresh water conduit).

[0065] In various embodiments, the recirculating shower system 400 can be configured to completely refresh the fluid within the system 400 within a predetermined time. For example, in various embodiments, the flow rate of fresh water dispensed through the shower head 500 (e.g., from the fresh water conduit 420) can be less than the flow rate of recirculated fluid pumped through the recirculated fluid conduit 425 and dispensed through the shower head 500, such that fluid is continuously recirculated through the system 400. For example, the shower head 500 can be configured to dispense fresh water at a flow rate of 2 liters per minute. The total volume of fluid within the system 400 can be approximately 1 liter. Therefore, in this embodiment, the system 400 is configured to completely refresh the fluid within the system 400 within 30 seconds. In various other embodiments, the flow rates of fresh water and recirculated fluid can be different.

[0066] As in Figure 11As shown in greater detail, the outer tube 450 can be configured to receive fresh water from a fresh water source (e.g., from the mixer 435 or directly from the fluid manifold). The outer tube 450 can completely enclose a portion of the recirculation fluid conduit 425. In various embodiments, the recirculation fluid conduit 425 can include one or more tubes made of various metallic or non-metallic materials (e.g., copper, plastic, aluminum, etc.). In various embodiments, the outer tube 450 can include one or more tubes made of various metallic or non-metallic materials (e.g., plastic, PVC, aluminum, copper, etc.). As described in greater detail below, the outer tube 450 can seal around a portion of the recirculation fluid conduit 425 such that fluid (e.g., fresh water) flowing within the outer tube 450 can flow between the outer tube 450 and the enclosed portion of the recirculation fluid conduit 425. Accordingly, the fluid (e.g., fresh water) within the outer tube 450 and the portion of the recirculation fluid conduit 425 can be configured to directly contact (e.g., fluid surrounding the conduit 425) such that heat can be exchanged between the relatively hot fresh water flowing through the outer tube 450 and the relatively cold recirculation fluid flowing through the recirculation fluid conduit 425.

[0067] As shown in Figure 10 and Figure 11 recirculation shower system 400 can be configured such that the relatively hot fresh water within the outer tube 450 and the relatively cold recirculation fluid within the recirculation fluid conduit 425 flow in opposite directions. For example, the relatively hot fresh water provided by the mixer 435 can flow through the outer tube 450 and be received by the coupler 455 through the fresh water conduit 420, as discussed in greater detail below. In these embodiments, the relatively hot fresh water flows from the mixer 435 (or manifold) in a generally downward direction toward a bottom end of the shower system 400 (e.g., toward the drain 430, toward the reservoir 415, etc.). The recirculation shower system 400 can be configured such that the relatively cold recirculation fluid flows in a direction opposite to the relatively hot water flowing through the outer tube 450. For example, as shown in Figure 10 and Figure 11 recirculation fluid can flow from the recirculation pump assembly 600 toward the showerhead 500. In these embodiments, the recirculation fluid flowing within the portion of the recirculation fluid conduit 425 enclosed by the outer tube 450 can flow in a direction opposite to the fresh water flowing within the outer tube 450. According to various other embodiments discussed in greater detail below, the recirculation shower system 400 can be configured such that the relatively hot fresh water and the relatively cold recirculation water flow in the same direction.

[0068] Figure 12 A perspective view of a showerhead 500 according to an example embodiment is shown. As shown in Figure 12As shown, the showerhead 500 can include multiple outlets. In various embodiments, the showerhead 500 can include at least one recirculating fluid outlet 505. In various embodiments, the showerhead 500 can include at least one fresh water outlet 510. As Figure 12 As shown, in various embodiments, the recirculating fluid outlet 505 can be larger in size than the fresh water outlet 510. For example, the recirculating fluid outlet 505 can be larger than the fresh water outlet 510 such that the recirculating fluid outlet 505 can pass (e.g., expel, dispense, etc.) detritus such as soap, hair, dirt, or other various cloggers. In various other embodiments, the recirculating fluid outlet 505 and the fresh water outlet 510 can be the same size. In various embodiments, the recirculating fluid outlet 505 can be configured to receive fluid from the recirculating fluid conduit 425, as described in greater detail below. In various embodiments, the fresh water outlet 510 can be configured to receive fluid from the fresh water conduit 420, as described in greater detail below.

[0069] In various embodiments, the recirculating shower system 400 can be configured to switch between various modes of operation. In various embodiments, the recirculating shower system 400 can be configured to receive user input (e.g., via the user interface 180). The recirculating shower system 400 can be configured to switch from one mode of operation to a second mode of operation based on the user input. For example, the recirculating shower system 400 can be configured to dispense recirculating fluid only through the recirculating fluid outlet 505 in a first mode of operation. The recirculating shower system 400 can be configured to dispense fresh water only through the fresh water outlet 510 in a second mode of operation. The recirculating shower system 400 can be configured to dispense both recirculating fluid through the recirculating fluid outlet 505 and fresh water through the fresh water outlet 510 in a third mode of operation. In various embodiments, the recirculating shower system 400 can include various components (e.g., valves, knobs, or other user input devices, etc.) that facilitate opening and / or closing the recirculating fluid conduit 425 (e.g., stopping fluid flow) and / or the fresh water conduit 420 (e.g., stopping fluid flow).

[0070] Figure 13 A side view of a recirculating pump assembly 600 is shown, in accordance with example embodiments. As discussed above, the recirculating pump assembly 600 can be configured to facilitate recirculation of fluid collected within the container 415. In various embodiments, the recirculating pump assembly 600 can receive collected fluid and other waste (e.g., soap, dirt, etc.) from the drain 430. In various embodiments, the waste can be expelled through a waste outlet 610 within a sump 605, as Figure 13A portion of the fluid collected within the sump 605 can be distributed toward the pump 615. The pump 615 can then be configured to pump the collected water through the recirculation fluid conduit 425 to be distributed back through the showerhead 500. Although Figure 13 The example embodiment depicted includes one sump 605, one waste outlet 610, and one pump 615, but various other embodiments can include more or fewer sumps 605, waste outlets 610, and pumps 615. In various embodiments, the recirculation pump assembly 600 can include more or fewer components, including but not limited to filters, water treatment pieces, and heaters. In various embodiments, the recirculation pump assembly 600 can be positioned in various other locations throughout the recirculating shower system 400.

[0071] Figure 14 A side view of a portion of the recirculating shower system 400 is shown, according to an example embodiment. Specifically, Figure 14 A side view of a coupler 455 between the outer tube 450 forming the heat exchanger 440 and the closed portion of the recirculation fluid conduit 425 is shown. As discussed above, recirculation fluid from the drain 430 can be pumped through the recirculation fluid conduit 425 to flow in an upward direction (e.g., in a general direction from the drain 430 to the showerhead 500). Fresh water can be provided by the mixer 435 (or through a water manifold system) to flow in a downward direction (e.g., in a general direction from the mixer 435 toward the reservoir 415). As Figure 14 As shown, the fresh water conduit 420 can be configured to couple to the outer tube 450 such that the fresh water conduit 420 can receive fresh water from the outer tube 450 and distribute the fresh water through the showerhead 500 (e.g., through the fresh water outlet 510). As discussed in more detail below, the coupler 455 can include several components to seal the outer tube 450 around the recirculation fluid conduit 425.

[0072] Figure 15 A perspective view of the showerhead 500 is shown, according to an example embodiment. As Figure 15 As shown, the showerhead 500 can include a recirculation fluid portion 520 configured to couple to a fresh water portion 525. In various embodiments, the recirculation fluid portion 520 can be configured to couple to the fresh water portion 525 through one or more retaining clips 530 (e.g., tabs, snaps, clips, etc.). In various embodiments, the showerhead 500 can include a latching retainer 535 and a spring-loaded latch 540, as Figure 15As shown. In various embodiments, the spring-loaded latch 540 may be configured to receive (e.g., compress, lock, attach, etc.) the latch retainer 535 to facilitate the coupling of the recirculating fluid portion 520 to the fresh water portion 525. In various embodiments, the recirculating fluid portion 520 may be configured to be coupled to the fresh water portion 525 by various fasteners (e.g., screws, adhesives, etc.). In various embodiments, the recirculating fluid portion 520 may be integrally formed with the fresh water portion 525 (e.g., welded, molded, etc.).

[0073] like Figure 15 As shown, the shower head 500 may include a recirculation fluid inlet 515. In various embodiments, the recirculation fluid inlet 515 may be configured to connect to a recirculation fluid conduit 425. In various embodiments, the recirculation fluid inlet 515 may be configured to connect to the recirculation fluid conduit 425 via various threaded components or fasteners. In various other embodiments, the recirculation fluid inlet 515 may be integrally formed with the recirculation fluid conduit 425. Figure 15 As shown, the shower head 500 may include a fresh water inlet 550. In various embodiments, the fresh water inlet 550 may be configured to connect to a fresh water conduit 420. In various embodiments, the fresh water inlet 550 may be configured to connect to the fresh water conduit 420 via various threaded components or fasteners. In various other embodiments, the fresh water inlet 550 may be integrally formed with the fresh water conduit 420.

[0074] Figure 16 A perspective view of a shower head 500 according to an exemplary embodiment is shown, wherein a recirculation fluid section 520 is coupled to a fresh water section 525. Figure 16 As shown, the recirculating fluid portion 520 can be configured to engage with the fresh water portion 525, such that the two portions form a shower head 500. In this embodiment, a retaining clip 530 helps to lock the recirculating fluid portion 520 within the fresh water portion 525, and a spring-loaded latch 540 compresses (e.g., via a spring) to receive a latch retainer 535. In various other embodiments, the recirculating fluid portion 520 and the fresh water portion 525 can be engaged in various other configurations (e.g., via fasteners, welding, molding, adhesives, etc.).

[0075] Figure 17 A bottom perspective view of a shower head 500 according to an exemplary embodiment is shown, wherein a recirculation fluid section 520 is connected to a fresh water section 525. Figure 17As shown, the recirculation fluid section 520 can be coupled to the fresh water section 525 such that a recirculation fluid nozzle 545 positioned on the recirculation fluid section 520 can be positioned within a recirculation fluid outlet 505' on the shower head 500. In various embodiments, the recirculation fluid nozzle 545 can be formed (e.g., welded, fastened, molded, etc.) to the recirculation fluid section 520 and configured to protrude from the recirculation fluid outlet 505', as... Figure 17 As shown. In various other embodiments, the recirculation fluid nozzle 545 may be formed with various other parts of the shower head 500, such as the fresh water section 525 (e.g., welded, fastened, molded, etc.). In various other embodiments, the shower head 500 may not include the recirculation fluid nozzle 545, such that the recirculation fluid is dispensed directly from the recirculation fluid outlet 505'.

[0076] like Figure 17 As shown, the shower head 500 can be configured such that the fresh water outlet 510' and the recirculation fluid outlet 505' are separate and distinct from each other (e.g., spaced apart). In various embodiments, the shower head 500 may include more than Figure 17 The depicted fresh water outlet 510' has more or fewer fresh water outlets. In various embodiments, the shower head 500 may include more than Figure 17 The depicted recirculation fluid outlet has more or fewer recirculation fluid outlets 505'.

[0077] Figure 18 A cross-sectional view of a shower head 500 according to an exemplary embodiment is shown. Figure 18 As shown, the recirculation fluid section 520 may include a recirculation fluid chamber 560. In various embodiments, the recirculation fluid chamber 560 may provide a pathway (e.g., a reservoir, channel, etc.) for recirculation fluid to flow from the recirculation fluid inlet 515 to the recirculation fluid nozzle 545 within the recirculation fluid outlet 505'. Figure 18 As shown, the fresh water section 525 may include a fresh water chamber 555. In various embodiments, the fresh water chamber 555 may provide a pathway (e.g., a reservoir, channel, etc.) for fresh water to flow from the fresh water inlet 550 to the fresh water outlet 510'. Figure 18 As shown, the recirculated fluid chamber 560 may be separate from and distinct from the fresh water chamber 555, such that the recirculated fluid and fresh water do not mix (e.g., merge, come into contact, etc.) within the shower head (e.g., before being dispensed from the outlet). In these exemplary embodiments, the recirculated fluid and fresh water may be dispensed simultaneously to the user within the recirculated shower system 400.

[0078] Figure 19 A schematic diagram of a recirculating shower system 400 according to an exemplary embodiment is shown. Figure 19As shown, the recirculating shower system 400 may include one or more shower heads (shown as shower head assembly 700). In various embodiments, the recirculating shower system 400 may include a first shower head within assembly 700 configured to distribute recirculated fluid to a user (shown as user 1000). In various embodiments, the recirculating shower system 400 may include a second shower head within assembly 700 configured to distribute fresh water to user 1000. In various embodiments, the recirculating shower system 400 may include two or more shower heads configured to distribute recirculated fluid and fresh water. In various embodiments, the recirculating shower system 400 may include one or more valves (e.g., diverter valves, three-way valves, etc.) operatively connected to a controller (e.g., knobs, switches, actuators, user interface 180, etc.) to control the flow of recirculated fluid and / or fresh water to the shower head assembly 700.

[0079] like Figure 19 As shown, the recirculating shower system 400 may include one or more temperature sensors 460 located at various locations throughout the recirculating shower system 400. The temperature sensors 460 may be configured to detect temperature values ​​at various locations, including but not limited to proximity to the fresh water outlet 510, proximity to the recirculated fluid outlet 505, within the heat exchanger 440, proximity to the drain outlet 430, or proximity to the mixer 435. The temperature sensors 460 may be configured to send a signal to a central controller system (e.g., control system 155) based on the detected temperature. In various embodiments, the temperature sensors 460 may be configured to facilitate the adjustment of a specified temperature (e.g., via the mixer 435, via the heat exchanger 440, etc.). In various embodiments, the temperature sensors 460 may be configured to facilitate the adjustment of a specified temperature based on user input (e.g., via one or more shower controls, knobs, user interface 180, etc.). For example, the control system 155 may be configured to process signals from the temperature sensors 460 and determine the operating conditions of the recirculating shower system 400 based on these signals. The control system 155 can be configured to send one or more control signals to various components of the recirculation shower system 400 based on operating conditions (e.g., increasing the input of hot water, decreasing the input of hot water, increasing the flow rate of fresh water, decreasing the flow rate of fresh water, etc.).

[0080] like Figure 19As shown, the recirculating shower system 400 can include one or more flow meters 470 positioned at various locations throughout the recirculating shower system 400. The flow meters 470 can be configured to detect the flow rate of recirculating fluid and / or fresh water at various locations, including but not limited to at the fresh water outlet 510, at the recirculating fluid outlet 505, within the heat exchanger 440, proximate the mixer 435, or proximate the pump 615. The flow meters 470 can be configured to send signals to the central controller system (e.g., control system 155) based on the detected flow rates.

[0081] In various embodiments, the flow meters 470 and / or temperature sensors 460 can be configured to facilitate adjusting a specified temperature (e.g., a temperature to be dispensed to the user 1000) within the recirculating shower system 400. For example, the control system 155 can be configured to process signals from the flow meters 470 and / or temperature sensors 460 and, based on these signals, calculate a required flow rate of recirculating fluid and / or fresh water to achieve a desired temperature of fluid dispensed to the user 1000. The control system 155 can be configured to calculate, based on the signals, a required temperature of fresh water provided from the mixer 435 (e.g., an amount of cold fresh water provided, an amount of hot fresh water provided) to achieve a desired temperature of fluid dispensed to the user 1000. The control system 155 can be configured to increase or decrease the flow rate of fluid within the mixer 435 and / or the temperature of fresh water based on the calculations. In these embodiments, the control system 155 can be configured to increase or decrease the flow rate and / or the temperature of fresh water such that the user 1000 "feels" (e.g., detects) a temperature change in a short period of time and substantially instantaneously (e.g., within 1 second, within 2 seconds, etc.). As a result, the system substantially eliminates the "thermal lag" that can be experienced in other systems, which is caused by a delay in the time a user wishes to increase the temperature to the time the user feels the water temperature change, often because other systems introduce hot water into a majority of the water flow, rather than directly to the user as in the present system. Thus, in the present system, if the user opens the shower door and cooler air enters the shower space, the system can detect this and automatically increase the flow and / or temperature of hot water that is directly flowing to the user so that the user experiences a substantially constant temperature on their skin.

[0082] As Figure 19As shown, the recirculating shower system 400 may include an ozone generator 900 operatively coupled to a fresh water conduit 420 (e.g., via an external conduit 450). In various embodiments, the ozone generator 900 may be configured to supply ozone to the fresh water conduit 420 (e.g., via electrolysis) to promote disinfection of bacteria, viruses, or other contaminants within the recirculating shower system 400. In various embodiments, the ozone generator 900 may be activated by user input. For example, the recirculating shower system 400 may include actuators (e.g., buttons, switches, user interface 180, etc.) that, when actuated, activate the ozone generator 900. In various embodiments, the ozone generator 900 may be activated for a predetermined amount of time (e.g., 5 seconds, 10 seconds, etc.). In various embodiments, the ozone generator 900 may be deactivated (e.g., turned off) based on user input. In various other embodiments, the ozone generator 900 may be operatively coupled to the control system 155, enabling the ozone generator 900 to automatically activate at predetermined times (e.g., once daily, once weekly, once monthly, etc.). In various embodiments, the recirculating shower system 400 may include one or more indicators, including but not limited to sound and / or visual effects, to indicate the activation of the ozone generator 900, enabling the user 1000 to detect the indicators. In various embodiments, the ozone generator 900 may be configured to provide ozone (e.g., via electrolysis) to the fresh water conduit 420 when the fresh water in the fresh water conduit 420 is at or below a specific temperature. For example, the temperature within the fresh water conduit 420 may be detected by one or more sensors (e.g., via temperature sensor 460, via flow meter 470, etc.). The sensors may be configured to send signals to a controller (e.g., the control system 155). The control system 155 may be configured to send one or more control signals to the ozone generator 900 to activate and / or deactivate based on the detected temperature.

[0083] like Figure 19 As shown, the recirculating shower system 400 may include a drain component 465 to facilitate the discharge of fresh water and / or recirculated fluid from the recirculating shower system 400 when the system 400 is not operating (e.g., off). In various embodiments, the drain component 465 may include a network of pipes, channels, etc., for receiving fluid when the system 400 is off. For example, the drain component 465 may be positioned within the recirculating shower system 400 at a point lower than the fresh water conduit 420 and / or the recirculated fluid conduit 425, such that when the recirculating shower system 400 is not operating (e.g., pump 615 is off, system 400 is off, etc.), gravity facilitates the discharge of fluid from the fresh water conduit 420 and / or the recirculated fluid conduit 425.

[0084] Figure 20A schematic of a recirculating shower system 400 is shown in accordance with an example embodiment. As shown Figure 20 The recirculating shower system 400 can be configured such that the heat exchanger 440’ includes recirculating fluid flowing substantially in the same direction as the fresh water, as shown Figure 20 The mixer 435’ can be positioned at a lower position (e.g., in line with the container 415, below the user 1000, etc.) such that the fresh water received by the outer tube 450’ is configured to flow in an upward direction (e.g., toward the showerhead 500), as shown. In this embodiment, the recirculating fluid can be pumped through the recirculating fluid conduit 425 that is enclosed within the outer tube 450’ such that the recirculating fluid and the fresh water flow substantially in the same direction to exchange heat with one another.

[0085] Figure 21 A cross-sectional view of a coupler 455’ is shown in accordance with an example embodiment. As shown Figure 21 The coupler 455’ can include a fitting 825 configured to couple the outer tube 450 to the recirculating fluid conduit 425 such that the outer tube 450 encloses a portion of the recirculating fluid conduit 425, as shown Figure 21 The coupler 455’ can include at least one O-ring 830 positioned within the fitting 825 to facilitate a seal of the outer tube 450 around the recirculating fluid conduit 425 to form a watertight seal, as shown Figure 21 The coupler 455’ can include a connector 805 configured to couple the fitting 825 to the fresh water conduit 420 such that fresh water can flow from the outer tube 450 to the fresh water conduit 420 and to the showerhead 500, as shown Figure 21 The coupler 455’ can include a compression nut 810 and a compression gland 815 coupled (e.g., via threads 820) to the fitting 825 to form a watertight seal and to help compress the fitting 825 around the recirculating fluid conduit 425 such that any fresh water from the outer tube 450 flows to the fresh water conduit 420, as shown

[0086] Figure 22 A cross-sectional view of a fitting 825’ is shown in accordance with an example embodiment. As shown Figure 22 Using a similar compression nut 810, compression gland 815, and O-ring 830 sealing configuration described above, the fitting 825’ can be configured such that fresh water flowing through the outer tube 450 can be configured to flow in various directions, as shown
