[0029] For a better understanding of the present disclosure, reference is made to FIGS. 1A-D which illustrate a whole house POE water filter system 100 for use with a manifold assembly 200 of the present disclosure. The water filter system 100 includes a cylindrical pressure vessel 106 which is stabilized in an upright position by a base 102. The cylindrical pressure vessel 106 is wrapped in a stainless steel cover 101. A top cover 110 provides access to one or more filter cartridges (not shown) in the interior of the pressure vessel 106. The water filter system 100 includes a lower fitting 103 as a drain port.

[0030] The top cover 110 includes a touch screen controller 111. Preferably, the controller 111 not only displays information but provides control of the manifold assembly 200. In one embodiment, the controller 111 includes a touch screen integrated with the top cover 110. The electronics for the controller 111 may be housed remotely or under the top cover 110. The controller 111 may communicate through wired and/or wireless channels.

[0031] A top portion 104 of the system 100 includes a cover hinge 114 that supports the top cover 110. The top portion 104 defines an inlet port 109a and an outlet port 109b in fluid communication with the filter cartridge (not shown) disposed inside the pressure vessel 106. The ports 109a, 109b are configured to connect to internal ports 210a, 201b of the manifold assembly 200, as further described below. Projections 112 (FIG. 1D) extend from the pressure vessel 106 on either side of the ports 109a, 109b for securing the manifold assembly 200 to the system 100. A vertical frame 108 extends between the top housing portion 104 and the base 102. The vertical frame 108 may create the cover 101 from a sheet of stainless steel and provide support for the manifold assembly 200.

[0032] Turning now to FIG. 2, the manifold assembly 200 of this disclosure for use with the water filter system 100 is shown in isolated perspective view. The manifold assembly 200 comprises a housing 204 having a curved surface 208 extending between two sides 216 of the housing 204 for fitting to the cylindrical outer surface of the pressure vessel 106. The curved surface 208 of the manifold assembly 200 includes an internal outlet port 210a and an internal inlet port 210b configured to be inserted into the corresponding ports 109a, 109b of the pressure vessel 106. When assembled together as shown in FIGS. 1A and 1B, the manifold assembly 200 is secured in place by fasteners (not shown) passed through the projections 112 into threaded bores 278 (see FIG. 3A) formed in the housing 204. A vertical slot 212 extends through the curved surface 208 between the ports 210a, 210b. The housing 204 has a top portion 205 and a bottom housing portion 207.

[0033] As best seen in FIG. 1B, the manifold assembly 200 is inserted against the inner pressure vessel 106 on the top housing portion 104 between the frame 108 and cover hinge 114. In another embodiment, the manifold assembly 200 is inserted against the inner pressure vessel 106 on the top housing portion 104 such that the vertical slot 212 can receive the frame 108 of the pressure vessel 106 for rotational stability. In another alternative embodiment, the vertical slot 212 receives the frame 108 and/or the hinge 114 for rotational stability.

[0034] Still referring to FIG. 2, the manifold assembly 200 includes an external inlet port 222a and an external outlet port 222b, each of which has fittings 224 for connection to the external water network. The manifold assembly 200 also includes two shut-off valve assemblies 300a, 300b that function in three modes of operation: normal; bypass; and shut off. In normal mode, the incoming water is filtered. In bypass mode, the water passes through the manifold assembly 200 without filtering. In shut off mode, incoming water is blocked for maintenance of the filter and the like. The shut-off valve assemblies 300a, 300b include knobs 302a, 302b for manual operation. Additionally, the shut-off valve assemblies 300a, 300b can be operated automatically by the controller 111 as described below.

[0035] FIGS. 3A-K illustrate a series of steps for assembly of the manifold assembly 200 in accordance with the subject technology. Referring now particularly to FIGS. 3A and 3B, bottom perspective views of the bottom portion 207 of the housing 204 are shown. The bottom housing portion 207 of the housing 204 forms an internal passageway 223 between the inlet port 222a and the outlet port 222b. The internal ports 210a, 210b are also in fluid communication with the internal passageway 223. The internal passageway 223 includes two vertical valve ports 220a, 220b and two vertical sensor ports 221a, 221b.

[0036] The inlet valve port 220a is in fluid communication with inlet port 222a via the sensor port 221a. The inlet valve port 220a is also in fluid communication with the internal outlet port 210a. Similarly, the outlet valve port 220b is in fluid communication with the internal inlet port 210b as well as the outlet port 222b via the sensor port 221b. The passageway 223 also extends between the two vertical valve ports 220a, 220b. The valve ports 220a, 220b each hold a shut-off valve assembly 300 (see FIGS. 3C, 3E, 3F, 5A, and 5B) for selectively opening and closing sections of the internal passageway 223. For example, in an operational position, water from the water network is configured to flow, for example, from external inlet port 222a to sensor port 221a to valve port 220a to outlet port 210a into the pressure vessel 106, and return after filtering through the internal inlet port 210b to valve port 220b to sensor port 221b to external outlet port 222b into the water network. The sensor ports 221a, 221b can hold flow, pressure, temperature, turbidity and/or other sensors for monitoring fluid in the internal passageway 223.

[0037] In the assembly step of FIGS. 3A and 3B, caps 232 are inserted to enclose the valve ports 220a, 220b of the manifold assembly 200. Sensor port caps 234a, 234b are also inserted into the sensor ports 221a, 221b. Various sensors or other devices (not shown) are inserted into the sensor ports 221a, 221b via the caps 234 and communicate signals to the controller. Alternatively, one or both sensor ports 221a, 221b may simply be unused and capped to seal and maintain the internal passageway 223 in a fluid tight manner.

[0038] In the assembly step of FIGS. 3C and 3D, upper perspective views of the bottom portion 207 of the housing 204 are shown. The fittings 224 are inserted into the external ports 222a, 222b and held in place with retainer clips 236. In this embodiment, a blank port plug 238 is inserted into the unused port 221a. A flow sensor 240 is secured within the flow sensor port 221b with a lock nut 244. The flow sensor 240 may be wired to or wirelessly send signals to the controller.

[0039] Assembly of the shut-off valve assemblies 300a, 300b in each valve port 220a, 220b is also shown in FIGS. 3C-3I. Prior to describing FIGS. 3C-3I in detail, it is proper to turn to FIGS. 5A-5E for a description of a shut-off valve assembly 300 because review now of the structure of the shut-off valve assembly 300 will facilitate understanding when the narrative returns to the assembly drawings. One of the shut-off valve assemblies 300 for insertion into a valve port 220a, 220b of the manifold assembly 200 is illustrated in a perspective view, side and cross-sectional view, respectively if FIGS. 5A-5C, respectively. Each valve assembly 300 includes a knob 302 coupled to a valve gear 305. A perspective view of the valve gear 305 is shown in FIG. 5D. The valve gear 305 slideably couples to a valve stem portion 304, which is shown in isolation in FIG. 5E.

[0040] The knob 302 has a central hole 340 for receiving a fastener 339. The knob's undulating outer circumference 342 makes for easy gripping by the user to pull and turn the shut-off valve assembly 300. Indicia 343 is provided on the knob 302 that may include instructions and/or orientation markings so the user can visually determine the setting of the shut-off valve assembly 300.

[0041] The valve gear 305 includes a central large diameter portion 306 having outer teeth 308. A top end stem 350 extends upward from the central large diameter portion 306. The top end stem 350 has a threaded central bore 351 for receiving the screw 339 to couple the valve gear 305 and knob 302 together. A lower or distal portion 354 extends downward from the central portion 305. The lower portion 354 couples to the valve stem portion 304. The lower portion 354 is a largely cylindrical sidewall 355 that defines a central bore 356. The sidewall 355 also defines an annular flexure slot 357 (see FIG. 5C) so that four radially inward fingers 358 can deflect outward.

[0042] Referring now to FIG. 5E, a top perspective view of the valve stem portion 304 is shown in isolation. The valve stem portion 304 includes a top stem 360 sized to slideably fit in the central bore 356 of the lower portion 354 of the valve gear 305. The top stem 360 approximates a quatrefoil in cross-section by having two sets of equally spaced opposing slots 362a, 362b. The top stem 360 also has a sealing ring 361.

[0043] One set of slots 362a are guide slots for capturing two opposing deflectable fingers 358. The fingers 358 are sized and configured to be captured in the guide slots 362a so that the rotational orientation of the valve stem portion 304 with respect to the valve gear 305 and knob 302 does not change when either of the valve gear 305 or knob 302 are rotated. Additionally, when the knob 302 is pulled upward or pushed downward, the guide slots 362a and fingers 358 again prevent relative rotation of the components of the shut-off valve assembly 300.

[0044] The other set of slots 362b also serve as guide slots for capturing two opposing deflectable fingers 358. However, the detent slots 362b are shallower to normally deflect the fingers 358 radially outward. Each detent slot 362b forms an upper detent 365 and a lower detent 366. The detents 365, 366 are radially inward depressions that capture the deflectable fingers 358. When in the detents 365, 366, the fingers 358 are undeflected. By pushing and pulling the knob 302, the user can feel the fingers 358 pop in and out of the detents 365, 366 to set a desired operational position of the shut-off valve assembly 300 as described further below.

[0045] Still referring to FIGS. 5A-5E, the top stem 360 is attached to a four-sided body 310. Three sides 311 of the body 310 define an opening 312, each one of the openings 312 is in fluid communication with the other two openings 312. The openings 312 are sized and configured to approximately match the internal passageway 223 of the manifold assembly 200. The fourth side 314 of the body 310 is blocked.

[0046] Referring again to FIGS. 3C and 3D, initial assembly of the shut-off valve assemblies 300 in the manifold assembly 200 is shown. Each valve stem portion 304 is inserted into the respective valve port 220a, 220b so that the openings 312 of the four-sided body 310 aligns with the internal passageway 223. A valve retaining nut assembly 322 slides over the stem 360 and threads into the respective valve port 220a, 220b to prevent or limit upward motion of the valve stem portion 304. The valve retaining nut assembly 322 also seals the valve ports 220a, 220b of the manifold assembly 200 so that fluid does not leak from the internal passageway 223.

[0047] In the next assembly step of FIGS. 3E and 3F, the valve gear 305 is coupled to the valve stem portion 304 of each valve assembly 300 with the deflectable fingers 358 in the slots 362a, 362b. Unlike the body 310, the valve gear 305 is free to move up and down on the stem 360 so that the fingers 358 can be positioned in either the upper detent 365 or the lower detent 366.

[0048] In the next assembly step of FIGS. 3G and 3H, perspective underside views of the top portion 205 of the housing 204 are shown. Motor assemblies 502 are mounted in the top portion 205 with screws 250 in mounting holes 251. Preferably, the screws 250 carry washers 253. The motor assemblies 502 communicate with and are driven by the controller. Each motor assembly 502 drives a motor gear 504 that selectively interacts with the teeth 308 of the valve gear 305 when the fingers 358 are in the lower detent 366. The motor gear 504 rotates about a pin 255 secured in a pivot hole 257 of the top portion 205.

[0049] In the next assembly step of FIG. 31, a partially exploded view of the manifold assembly 300 is shown. With the motor assemblies 502 secured in place, the top portion 205 is fastened to the bottom housing portion 207 with fasteners 260 such that the valve stems 304 extend through stem openings 252 in the top portion 205. The knobs 302 are then mounted on each valve portion 304 with fasteners 339 to complete the manifold assembly 300 as shown in FIG. 2.

[0050] In a final assembly step of FIGS. 3J and 3K, a mounting bracket 219 is attached to threaded shoulders 337 of the bottom housing portion 307 of the manifold assembly 200 with fasteners 331. The mounting bracket 219 has slots 332 so that a vertical portion 333 may be set flush against an adjacent surface (not shown). Additional holes may be drilled in the vertical portion 333 to receive fasteners (not shown) so that the manifold assembly 200 and, in turn, the POE system can be secured in place with reduced likelihood of being inadvertently knocked over. It is envisioned that the controller, sensor(s), and/or motor assemblies 502 have wiring (not shown) extending from the bottom housing portion 307 for power and the like. The mounting bracket 219 secures the water filter system 100 to a wall or other support structure. The manifold assembly 200 receives power and/or other electrical signals from wiring (not shown) or may run on battery power.

[0051] Referring now to FIG. 4A, the manifold assembly 200 is shown in cross-section fully assembled. The manifold assembly 200 may be operated in two different modes: automatic mode; and manual mode. Also referring to FIGS. 4B and 4C, cross-sectional views of a portion of the manifold assembly 200 are shown in automatic mode and manual mode, respectively. Advantageously, each valve assembly 300 in the manifold assembly 200 saves on cost and complexity by being interchangeable. The knobs 302 are used to switch between the manual and automatic modes of operation.

[0052] In the automatic mode of FIGS. 4A and 4B, the motor assembly 502 may receive control signals from the controller 111. Based upon certain circumstances, the controller 111 may automatically switch the manifold assembly 200 between the modes of FIGS. 6A-C as described below. As can be seen in FIGS. 4A and 4B, the motor gear 504 is engaged with the teeth 308 of the gear portion 305. Thus, when the controller drives the motor gear 504, the gear portion 305 turns. As a result, the valve portion 304 turns to the desired position. Sensors may also be used to verify proper positioning of the valve portion 304.

[0053] The user can verify that the manifold assembly 200 is in the automatic position by pushing down on the shut-off valve assembly 300. When the knob 302 is pushed downward by the user, the valve gear 305 moves downward so that the deflectable fingers 358 come to rest in the lower detent 366. This aligns the outer teeth 308 of the valve gear 305 to engage the corresponding teeth 504 on the motor gear 506. Although downward movement of the knob 302 is limited by a top portion 205 of the manifold assembly 200, the deflectable fingers 358 of the valve gear 305 popping into the lower detent 366 on the valve stem portion 304 provide tactile feel to the user to communicate that the knob 302 is properly in the automatic mode position.

[0054] However, as shown in FIG. 4C, if the knob 302 is pulled upward by the user, the respective valve assembly 300 is put into a manual mode such that manual rotation of the knob 302 controls the position of the valve assembly 300. As noted above, indicia 343 may be provided on the knob 302 and/or the top portion 205 so that the user can visually set the position of the knob 302. When the knob 302 is pulled upward, the fingers 358 deflect out of the lower detent 366 on the valve stem portion 304 and slide upward in the slots 362a, 362b until the fingers 358 engage the upper detent 365 on the valve stem portion 304. The valve gear 305 moves up into a raised portion 209 of the top portion 205, which provides a hard stop to the central portion 306 but the user gets a tactile response when the fingers 358 engage the upper detent 365 to indicate the desired manual position. In either case, the outer teeth 308 of the valve gear 305 rise above and disengage from the teeth 504 of the motor gear 506. Thus, the position of the valve assembly 300 is solely controlled by manual rotation of the knob 302 so that the knob 302 can be manually rotated to a desired position.

[0055] To return to the automatic mode, the knob 302 is simply pushed downward so that the deflectable fingers 358 ride down the slots 362a, 362b and re-engage the lower detents 366 and, thus, the valve gear 305 lowers to become re-engaged with the motor gear 506. A sensor, such as a Hall Effect sensor, may be used as feedback, or internal sensors on the motor assembly 502 can be used to properly align and/or verify that the shut-off valve assemblies 300 are in the proper automatic mode and/or manual operation position.

[0056] When the valve assemblies 300 are inserted into the valve ports 220a, 220b of the manifold assembly 200, the manifold assembly 200 can be set to three different positions, as shown schematically in FIGS. 6A-C. As shown in FIG. 6A, the manifold assembly 200 is in a shutoff position, in which the blocked portions 314 of the body 310 of the valve assemblies 300 are rotated within the valve ports 220a, 220b to face the external ports 222a, 222b. As a result, the flowpath from the water network into or out of the manifold assembly 200 is blocked. The shutoff position is useful for maintenance of the filter and like maintenance operations. It is noted that only facing the blocked portion 314 of the body 310 in valve portion 220a to the external inlet 222a may be used to shut off flow.

[0057] In the bypass position, shown in FIG. 6B, the blocked portions 314 of the valve assemblies 300 are rotated within the valve ports 220a, 220b to face the internal ports 210a, 210b. Thus, water can flow from the water network through the external port 222a and through the internal passageway 223, including the valve ports 220a, 220b, and out of the external port 222b, while being prevented from flowing into or out of the pressure vessel 106 through the internal ports 210a, 210b. Advantageously, the bypass position effectively allows taking the filter offline without otherwise interfering with water flow in the house water network.

[0058] In the normal operational position, shown in FIG. 6C, the blocked portions 314 of the valve assemblies 300 are rotated within the valve ports 220a, 220b to face each other. Thus, water flows into inlet port 222a through the first body 310 of the valve assembly 300 to pass out the internal outlet port 210a into the pressure vessel 106 for filtering. After passing through the filter, the filtered water re-enters the internal passageway 223 via the internal inlet port 210b and passes through two openings 312 of the body 310 of the second valve assembly 300 in valve port 220b. Then, the filtered water exits via outlet port 222b into the house water network.

[0059] In an alternative embodiment, the manifold assembly 200 does not include detents to set the automatic and manual modes. Instead, a bias spring surrounds the top end stem 350 and is compressed between the central large diameter portion 306 and the top portion 209 of the housing 204. As a result, the spring biases the valve gear 305 downward into the automatic mode. To operate in manual mode, the user must pull up on the knob 302 to overcome the bias spring and disengage the central large diameter portion 306 from the motor assembly 502, then the knob 302 can be rotated. When the knob 302 is released, the spring force presses the valve gear 305 downward again into engagement with the motor assembly 502.

[0060] Referring now to FIG. 7, touch screen display 700 of the controller 111 is shown. It is envisioned that similar displays as available on the controller 111 may be presented on a mobile device in communication with the controller 111 to accomplish identical functionality. As noted above, the controller 111 may be integral with the top cover 110 (FIG. 1) with a touch screen for displaying information and receiving user input. The controller is preferably able to present a plurality of different displays or graphical pages by navigating through a menu driven display and the like. The controller 111 may also process signals from sensors and/or receive input wirelessly from a linked smart phone running a specific application.

[0061] In the display 700, the date and time are shown in a top area 702. The upper left hand corner 704 includes a settings icon 704 for accessing a series of settings for configuration of the controller 111. The corner 704 also has a cellular connectivity icon 708 and a wireless WiFi icon 710. A title area 712 provides headline information regarding the display. In this case, the “Leak Sensor” page is shown. The display 700 also includes a home icon 714 for accessing a plurality of various pages and displays as needed to review and direct operation of the controller 111.

[0062] Another area 716 shows the status of the leak sensor monitoring, in this case as “on.” The leak sensors may be in the base 102 or at the bottom of the pressure vessel 106 (see FIG. 1) as well as other places such as the water heat, sump pump, one or more sinks, toilet areas and the like where undesired water leakage may occur. The leak sensors can be puck shaped devices that connect to the controller 111, whether wired or wirelessly. The leak sensor send a signal for actuating the manifold assembly 200 for automatic closing of the water supply (e.g., the shutoff position) in the event of a leak.

[0063] By using the controller 111, the user can pair a plurality of lead sensors and give each sensor a name as shown on the display 700 in area 718. Each sensor is depicted with the respective name, coloration to indicate status (e.g., blue as active and normal operation), and a battery life indication if relevant. The display 700 can change the color (e.g., red to indicate an error condition) or otherwise (e.g., flashing indicates error) indicate the leak sensor that generated the leak signal. Once the error condition is remedied, the controller touch screen can be used to select the “Reset Sensor” button 720.

[0064] Another exemplary sensor would be a RFID sensor to read a RFID tag on the replacement filter cartridges. By collecting information regarding the filter cartridge associated with the RFID tag, the controller 111 can verify a proper filter is being used as well as check inventory to prevent fraud. For example, the controller 111 can read a serial or inventory number that is checked against a master list accessed by the cloud.

[0065] Still another sensor may be a flow sensor for monitoring the amount of water having passed through the filter. Based on a predetermined threshold, such as 100,000 gallons of use, the controller 111 may provide a text reminder to the cell phone of the homeowner regarding the need to change to the filter. The controller 111 may also display a screen indicating that the remaining filter life as well as provide updates and reminders to the homeowner regarding such maintenance.

[0066] The controller 111 may communicate with an irrigation system. Thus, based on a signal from the irrigation system, the controller 111 may switch the manifold 200 into the bypass position during watering of the lawn to conserve filter life. After completion of the irrigation cycle, the controller 111 returns the manifold 200 to the normal position. Alternatively, the controller 111 may include a time clock synchronized to the irrigation system. By being synchronized with the irrigation system, the controller 111 may simply switch to the bypass position during the watering times based upon accessing the stored watering time data. Further, the controller 111 may incorporate irrigation control so that not only is the manifold 200 controlled by the controller 111, but the irrigation components as well. Such usage may be accessed via menu of the touch screen display or via a software application on a smart device such as a laptop, tablet and cell phone.

[0067] Referring now to FIGS. 8A and 8B, bottom perspective views of another manifold 800 are shown. Similar elements to those described in connection with above-described embodiments are indicated with the like reference numbers. Many elements are essentially the same as those of the foregoing embodiments and, thus, are not further described herein. The following discussion is directed to the primary differences.

[0068] The bottom portion 807 of the housing 804 includes sensor retainers 834a, 834b and valve retainers 832a, 832b. The valve retainers 832a, 832b include indicia to help with proper orientation during assembly. A flat cover 839 seals the bottom portion 807 and holds the retainers 832a, 832b, 834a, 834b in place. The flat cover 839 is attached using fasteners 841. The flat cover 839 includes mounting holes 843 for attaching the mounting bracket (not shown) that secures the water filter system 100 to a wall or other support structure.

[0069] While the disclosure has been particularly shown and described with references to preferred examples thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present application as defined by the appended claims. Such variations are intended to be covered by the scope of this present application. As such, the foregoing description of examples of the present application is not intended to be limiting, the full scope rather being conveyed by the appended claims.
