Description

[0001] This application is a divisional application of the original application with an application date of April 24, 2020, application number 202080031518.5, and invention name “Water Treatment System”. Technical Field

[0002] The present invention relates to water treatment systems and, more particularly, to point-of-use water treatment systems for residential applications. Background Art

[0003] Conventional water treatment systems are typically used to treat water for human consumption. Such treatment systems may be configured to remove pathogens, chemical contaminants, and turbidity from water. Many conventional treatment methods can be broadly categorized as solid separation using physical and / or chemical processes or sterilization using heat, radiation, or chemical additives. For example, conventional water treatment systems typically include carbon filtration, carbon-free filtration, distillation, ozone treatment, reverse osmosis, ion exchange components, chlorination components, aeration components, advanced oxidation process components, coagulation components, sedimentation components, or ultraviolet radiation components.

[0004] Conventional point-of-use water treatment systems are designed to be used at a single water outlet, such as a sink or water dispenser. Conventional point-of-use water treatment systems are connected to a pressurized water source to treat the water as it is dispensed. In some applications, the water treatment system is located on a countertop near the sink. In countertop applications, the water treatment system is often connected to the end of the faucet so that the water leaving the faucet can pass through the water treatment system before being dispensed. In many applications, countertop space is limited, especially for conventional water treatment systems, which are less likely to be easily repositioned for storage than kitchen utensils or cutting boards. For this reason, many times, conventional countertop treatment systems are arranged in areas that are less used than other areas of the countertop, such as against walls and under upper cabinets in the kitchen. Although this positioning of conventional water treatment systems is considered an acceptable use of counter space, it is often necessary to remove or require large-scale repositioning of the system for maintenance (e.g., filter maintenance).

[0005] In other applications, the water treatment system is located below the countertop, for example, in a cabinet under a sink. In a typical undercounter application, the water treatment system is connected to a water supply line upstream of a standard faucet. In such an application, the water treatment system can be coupled to an auxiliary faucet mounted near the sink above the counter to dispense treated water. The space under the sink may be limited, such as when plumbing and other appliances (e.g., a garbage disposer) are present. Due to this limited space, similar to countertop arrangements, water treatment systems are often arranged in locations that are considered less likely to interfere with daily use of the space under the sink, such as a back corner. While this positioning may be considered acceptable, maintenance work (e.g., filter replacement) may be hindered by the positioning. Summary of the invention

[0117] I. Water Treatment System Overview

[0118] The water treatment system 100 according to one embodiment of the present invention is Figure 1A-1E and Figure 2A-2F 1 and generally designated 100. The water treatment system 100 in the illustrated embodiment includes a treatment assembly 130 and a base assembly 110. The water treatment system 100 may include a removable cover 120 configured to engage with the base assembly 110 to conceal one or more or all aspects of the treatment assembly 130. In one embodiment, the removable cover 120 may conceal the treatment assembly 130 to provide an aesthetic effect to the water treatment system 100 so that the water treatment system 100 is positioned on a countertop or is visible during daily use.

[0119] The removable cover 120 can provide a detachable and / or replaceable aesthetic housing structure that can update or change the shape, material, and color of the water treatment system 100. For example, in one application, the removable cover 120 can be replaced with another removable cover 120 having one or more different aspects related to shape, material, or color, or a combination thereof. In addition, or alternatively, similar to the removable cover 120, the back cover 310 can provide an aesthetic housing structure. In one embodiment, the back cover 310 can be detachable and / or replaceable to facilitate changing the appearance.

[0120] In one embodiment, the water treatment system 100 may include UV disinfection capabilities. The water treatment system 100 may include a UV disinfection assembly as described herein that provides such UV disinfection capabilities. In one embodiment, the UV disinfection assembly may include a long-life / permanent LED reactor assembly that may require substantially no routine maintenance or consumable lamp replacement and is housed in a permanent mounting location within the base assembly 110. It should be understood that the present invention is not limited to maintenance-free or permanent LED reactor assemblies; the LED reactor assemblies may be replaceable or serviceable, or both. It should also be understood that the UV disinfection assembly may include a UV energy source other than an LED source, including, for example, a fluorescent UV source (CFL), to provide disinfection capabilities.

[0121] shown Figure 1A-1E and Figure 3A-3G Treatment assembly 130 in an embodiment may be removable from base assembly 110 so as to facilitate installation or placement of water treatment system 100 for operation in a space that restricts access to one or more sides or portions of water treatment system 100 (e.g., upper portion 102, rear portion 103, side portion 104, or base portion 105, or combinations thereof). As an example, the space between upper portion 102 and another object (e.g., an upper cabinet) may be small enough so that access to upper portion 102 is limited or vertical displacement of one or more components of water treatment system 100 (e.g., treatment assembly 130) is limited. In one embodiment, water treatment system 100 may be considered to include a "flat" aspect ratio that preserves usable work space in an above-counter installation and substantially minimizes intrusion of storage space in an under-counter arrangement.

[0122] In the illustrated embodiment, as further described in detail herein, the treatment assembly 130 can be pivoted or tilted relative to the lower portion of the base assembly 110 or the base 105 so that the upper portion of the treatment assembly 130 is separated from the base assembly 110 while the lower portion of the treatment assembly 130 remains in contact with the base assembly 110. In other words, the accessible filter box or treatment assembly 130 can be disengaged from the base assembly 110, and the base assembly 110 can be permanently installed above or below a countertop or sink. In an under-counter installation, the treatment assembly 130 can be disengaged from the base assembly 110 to facilitate the removal of the consumable filter from the treatment assembly 130 without interfering with the pipes that connect the base assembly 110 to the water source and the treated water outlet that is in fluid communication with the point-of-use distribution outlet. In one embodiment, the treatment assembly 130 or the water tank assembly can be disengaged from the locked position (wherein the treatment assembly 130 is nested in the base assembly 110 or the frame assembly) so that the treatment assembly 130 is pivoted relative to the base assembly 110. In the pivoted position, also described as a secure "rest" position, the treatment assembly 130 can be configured to rest securely in a tip-out arrangement to facilitate management of hand placement and meet lifting parameters for lifting and carrying the treatment assembly 130 to a sink for opening and filter replacement activities. In other words, the treatment assembly 130 can be pivoted from an engaged position with the base assembly 110 to a pivoted position in which the treatment assembly remains substantially stable. The treatment assembly 130 can be prevented from further pivoting at the pivoted position so that the treatment assembly 130 does not simply fall out of the base assembly 110 or loosely disengage.

[0123] It should be understood that the present invention is not limited to a tilted configuration for removing the processing assembly 130 from the base assembly 110 , and that the processing assembly 130 and the base assembly 110 may be configured differently for removing the processing assembly 130 from the base assembly 110 .

[0124] In one embodiment, removable cover 120 may be engaged and disengaged with base assembly 110 in a direction substantially parallel to the surface on which base assembly 110 is disposed. In this manner, removable cover 120 may facilitate access to treatment assembly 130 when water treatment system 100 is located in a spatially constrained location that may limit access to water treatment system 100 along one or more sides or portions of water treatment system 100 as described herein.

[0125] The water treatment system 100 is operable to receive untreated water from a water source, such as a cold water service line configured to supply water under pressure, via an inlet pipe 112. The water treatment system 100 is also operable to treat the untreated water received from the water source and deliver the treated water to an outlet pipe 114, which can be coupled to a distribution point to deliver the treated water to a point of use. The distribution point can correspond to an auxiliary faucet, but the present invention is not limited thereto. For example, the distribution point can be a diverter attached to an existing sink faucet.

[0126] In one embodiment, water connections for the inlet and outlet pipes are housed or provided in a space below the unit accessible to the installer. The connectors may provide rotational capability to align system components during installation.

[0127] In one embodiment, the processing assembly 130 may include a closure assembly 132 or a lift-off sump cover that enables tool-less access to a container 134 (also described as a pressure vessel or a removable sump or processing vessel) and exposes the surface of the container 134 for cleaning (e.g., enabling the use of simple cleaning methods).

[0128] Treatment assembly 130 may include a treatment assembly inlet 131 (e.g., a water inlet) operable to receive water from water inlet pipe 112 via base assembly inlet passage. Treatment assembly inlet 131 of treatment assembly 130 may include a one-way valve or check valve coupled thereto (e.g., arranged in line with treatment assembly inlet 131 of container 134) to substantially prevent leakage of water remaining in treatment assembly 130 during transport to a service location (e.g., typically a water collection container or, more commonly, a kitchen sink). The check valve may also satisfy certain regulatory requirements that the unit may need to comply with.

[0129] The closure assembly 132 (e.g., also described as a cover assembly or a sink closure assembly) of the treatment assembly 130 may include a handle assembly 136 that is operable to secure the treatment assembly 130 into a slot or receiving space provided by the base assembly 110. Operation of the handle assembly 136 from an operable position 261 (e.g., a disengaged position) to an engaged position 262 may facilitate forming a watertight connection between the base assembly 110 and the treatment assembly 130 such that they resist water connection tendencies. For example, the treatment assembly 130 and the base assembly 110 may be engaged and engaged in a position in response to operation of the handle assembly 136 such that, as a structural system under pressure, both the top and bottom of the treatment assembly 130 are prevented from separating and the water inlet and outlet are prevented from leaking.

[0130] In the illustrated embodiment, the treatment assembly 130 is oriented to the base assembly 110 by an alignment member 137 (e.g., a "foot" extension) extending from a lower portion 141 of the treatment assembly 130, the alignment member 137 being operable to roughly position the treatment assembly 130 to the base assembly 110, connect the water inlet coupling 231 (e.g., a water inlet connection) of the treatment assembly 130 to the water supply coupling 332 (e.g., a water supply connection) of the base assembly 110, and connect various aspects of the handle assembly 136 (e.g., a latch mechanism) to the upper portion of the base assembly 110. In one embodiment, the alignment member 137 can be arranged so that the treatment assembly 130 can be oriented in any of three 120 degree regions relative to the base assembly 110 (although other spacings can be achieved). Improper orientation is substantially prevented via the arrangement of the alignment member 137 and the handle assembly 136, making it impossible to position and engage the locking mechanism without the treatment assembly 130 and the base assembly 110 being aligned. As discussed herein, the base assembly 110 may include a corresponding number of base assembly receivers 342 operable to receive the alignment members 137 of the processing assembly 130 .

[0131] In one embodiment, the handle assembly 136 is operable to move to an engaged position 262 in which the handle assembly 136 is rotated or folded into a flat surface relative to the upper surface of the treatment assembly 130. The treatment assembly 130 and the base assembly 110 can be configured such that the handle assembly 136 can be arranged in the engaged or engaged position 262 (e.g., a flat arrangement) only when the orientation is correct and a watertight connection can be made between the treatment assembly 130 and the base assembly 110.

[0132] An alternative embodiment of the water treatment system is Figure 52A-Figure 52E , Figure 4 and Figure 53A-Figure 53E 100'. Water treatment system 100' is similar in many respects to water treatment system 100, including a treatment assembly 130', a base assembly 110', and a removable cover 120'. Treatment assembly 130' is operable to pivot or tilt relative to a lower portion or base 105' of base assembly 110' while the lower portion of treatment assembly 130' remains in contact with base assembly 110'. As discussed herein, handle assembly 136' can be positioned between an operable position 261' and an engaged position 262' relative to base assembly 110' to facilitate forming a watertight connection between base assembly 110' and treatment assembly 130'.

[0133] The treatment assembly 130' in the illustrated embodiment may include a plurality of alignment members 137' extending from a lower portion 141' of the treatment assembly 130' and arranged to facilitate alignment between the treatment assembly 130' and the base assembly 110'. The alignment members 137' may be angularly spaced around the longitudinal axis 234' of the treatment assembly 130' in a uniform manner. As discussed herein, the treatment assembly 130' may include a closure assembly 132' and a container 134', the closure assembly 132' being operable to be coupled to the container 134' at a plurality of angular orientations. Each angular orientation at which the closure assembly 132' is coupled to the container 134' may be aligned with the angularly spaced alignment members 137' to align with the base assembly 110', thereby forming a watertight connection between the base assembly 110' and the treatment assembly 130'. The alignment members 137' may be received by the base assembly receiving portion 342', respectively. As such, the alignment features 137' may assist in engaging the handle assembly 136' to the base assembly 110' to form a watertight connection between the handle assembly 130' and the base assembly 110'.

[0134] The alignment member 137' in the illustrated embodiment differs from the configuration of the alignment member 137 in that the alignment member 137' includes a foot that extends radially relative to the longitudinal axis 450' of the treatment assembly 130'. However, it should be understood that the alignment member 137' can be configured more similar to the alignment member 137 without the foot. The water treatment system 100' is described herein as having a plurality of components that are similar or different from the respectively named or located components of the water treatment system 100 and the additional embodiments of the water treatment systems described herein; it should be understood that any component of the water treatment system 100 can be incorporated into the water treatment system 100' and the additional water treatment systems described herein. Likewise, any component of the water treatment system 100' and the additional water treatment systems described herein can be incorporated into the water treatment system 100. In addition, it should be understood that any one or more components of the water treatment system 100, the water treatment system 100', and the additional water treatment systems described herein may not be present in these embodiments to form alternative embodiments.

[0135] In the illustrated embodiment, water treatment system 100' can include an upper portion 102', a rear portion 103', a side portion 104', and a base 105', or a combination thereof, that are similar in many respects to upper portion 102, rear portion 103, side portion 104, and base 105 of water treatment system 100. Water treatment system 100' can include a UV disinfection assembly that provides UV disinfection capabilities.

[0136] The water treatment system 100' includes an inlet pipe 112' and an outlet pipe 114', which are respectively configured to receive water from a water source and provide treated water to a point of use.

[0137] The treatment assembly 130' of the water treatment system 100' may include a container 134' and a closure assembly 132' removable from the container 134' to provide access to an interior space of the container 134' and a filter assembly 170' disposed in the closure assembly 132'.

[0138] Water treatment system 100' can include an inlet coupling 231' that forms part of a treatment assembly inlet 131' of treatment assembly 130'. Inlet coupling 231' can form a fluid-tight connection with a water supply coupling 332', similar to the connection between inlet coupling 231 and water supply coupling 332 of water treatment system 100.

[0139] II. Processing components

[0140] According to one embodiment of the present invention, the processing component 130 Figure 5-Figure 10 and Figures 11A-11H 130 is further shown in detail in the illustrated embodiment. The processing assembly 130 in the illustrated embodiment includes a closure assembly 132, which is operable to seal an opening 138 of a container 134. The container 134 can be a walled structure, the size and shape of which are suitable for receiving a primary filter 150 (also described as a pre-filter) and a filter assembly 170. As previously described, the container 134 can include an opening 138, the size of which is sufficient to allow replacement of the pre-filter (e.g., the primary filter 150) or the filter assembly 170, or both. The size of the opening 138 can also be sufficient to enable the interior space of the container 134 to be cleaned using conventional cleaning methods.

[0141] The container 134 in the illustrated embodiment can include a lower portion 141, which also defines a lower portion of the treatment assembly 130. The lower portion 141 can include a plurality of alignment members 137 as described herein. The alignment members 137 can be configured to facilitate alignment of the container 134 with the base assembly 110. Additionally or alternatively, the alignment members 137 can facilitate stabilizing the treatment assembly 130 in an upright position on a generally horizontal surface (e.g., a countertop or sink) for maintenance.

[0142] The alignment member 137 may be Fig. 11B and Fig.11H As seen in the illustrated embodiment, and arranged at equally spaced angular orientations relative to the central axis 234', such that each alignment member 137 is arranged at an angle a relative to each adjacent alignment member 137 (the center being defined by the longitudinal axis 234' and the lower portion 141).

[0143] In the exploded view without the closure assembly 132' Fig.13In the illustrated alternative embodiment including the treatment assembly 130', the treatment assembly 130' may include an alignment member 137' having a leg 143' extending from a lower portion 141' of the container 134'. At or near the end of the leg 143' distal from the lower portion 141' of the container 134', the alignment member 137' may include a foot 145' extending horizontally (and optionally extending radially outward relative to a central axis 234' of the container 134') to define a support surface. In one embodiment, one or more or all of the feet 145' may engage the frame assembly or base assembly 110 to facilitate alignment and optionally enhance bottom sealing (e.g., the connection between the water supply coupling 332' and the water inlet coupling 231' of the treatment assembly inlet 131'), thereby potentially enhancing bottom sealing in an upright mounted position of the treatment assembly 130'. The collective feet 145' of the plurality of alignment members 137' can stabilize the processing assembly 130' in an upright position on a generally horizontal surface for maintenance. In one embodiment, the feet 145' on the container 134' allow the processing assembly 130' to stand upright on any horizontal surface during installation or removal.

[0144] Returns a description of the processing component 130, such as Fig.10 As depicted in the illustrated embodiment, the opening 138 of the container 134 can be sealed by the closure assembly 132, which can be configured to engage one or more ramp structures 139 (e.g., ramps) arranged circumferentially around the perimeter of the opening 138. In the illustrated embodiment, the handling assembly 130 includes three ramp structures 139; however, the present invention is not limited thereto. As an example, the handling assembly 130 can include a single ramp structure 139 in the form of a thread with a single starting point to facilitate the engagement of the closure assembly 132 on the opening 138 of the container 134. The plurality of ramp structures 139 can facilitate the conversion of the rotational movement of the closure assembly 132 relative to the container 134 into a linear motion to close and form a watertight seal around the opening 138 of the container 134. The three ramp structures 139 in the illustrated embodiment can operate as separate threads that define three starting points for the closure assembly 132 to engage the container 134 and close the opening 138 of the container 134.

[0145] In the illustrated embodiment, the ramp structures 139 correspond in number to the number of alignment members 137 extending from the lower portion 141 of the container 134. One or more of the ramp structures 139 may include a stop 146 (e.g., a closure assembly stop 241) operable to engage a corresponding component of the closure assembly 132. In the illustrated embodiment, the stop 146 is disposed at or near the closed end of the ramp structure 139, and when engaged with the closure assembly 132, the stop 146 prevents the closure assembly 132 from further rotating about the container 134, thereby defining a closed position of the closure assembly 132 relative to the container 134. For example, the ramp structure 139 in the illustrated embodiment corresponds to three 120° spiral ramps on the collar 242 (e.g., a closure ring) to engage the three ramp structures of the container 134.

[0146] exist Fig.13 and Fig.15 In the illustrated alternative embodiment, the closure assembly 132' and the container 134' are shown having a stop 146' disposed at or near the starting end of each ramp structure 139', and when engaged with the closure assembly 132', the stop 146' prevents the closure assembly 132' from further rotating around the container 134', thereby limiting the closed position of the closure assembly 132' relative to the container 134'.

[0147] It should be understood that the stop portions 146, 146' can be Fig.10 , Fig.13 and Fig.15 As an example, the stop 146 may be provided in the form of a depression or notch along the inclined surface of the ramp structure 139 that engages a corresponding protrusion defined by the closure assembly 132 in the closed position.

[0148] exist Figure 5-Figure 10 and Figures 11A-11H In the illustrated embodiment, the closure assembly 132 and / or the container 134 are provided with registration elements to indicate that the closure assembly 132 and the container 134 are fully engaged with each other. The container 134 in the illustrated embodiment includes a plurality of registration elements 148, the number of which is equal to the number of available engagement positions of the closure assembly 132 relative to the container 134. For example, the number of registration elements 148 can be equal to the number of ramp structures 139, so that regardless of the starting orientation of the closure assembly 132 relative to the container 134 and regardless of which ramp structures 139 engage which closure assembly ramps 266, the engagement position of the closure assembly 132 relative to the container 134 results in registration with one of the plurality of registration elements 148.

[0149] In the illustrated embodiment, the closure assembly 132 includes a closure assembly registration element 147 that is aligned with one of the plurality of registration elements 148 at a position corresponding to full engagement of the closure assembly 132 relative to the container 134. This alignment can serve as a visual indication to a user coupling the closure assembly 132 to the container 134 that full engagement has or has not been achieved. Alternatively, the closure assembly registration element 147 can correspond to the angular orientation of the receiving element 267 of the closure assembly 132.

[0150] Note that, in one embodiment, the closure assembly 132 is operable to engage with the container 134 such that, in the engaged position, the closure assembly 132 is aligned with the alignment member 137. This alignment, combined with the base assembly receiver 342 receiving the alignment member 137, provides alignment between the closure assembly 132 and the base assembly 110 for engaging the handle assembly 136 to form a watertight connection. In one embodiment, if the closure assembly 132 is not fully engaged with the container 134 (e.g., the closure assembly 132 is partially rotated to engage the container 134 but the stop 146 is not engaged), alignment between the closure assembly 132 and the alignment member 137 may not be achieved, and therefore, attempting to connect the closure assembly 132 to the base assembly 110 may be impossible or impractical.

[0151] exist Fig.10 , Fig.13 and Fig.15 In the illustrated embodiment, one or more stops 146, 146' of the container 134, 134' can be positioned so that the closed position of the closure assembly 132, 132' is aligned with the alignment member 137, 137' extending from the lower portion 141, 141' of the container 134, 134'. As described herein, the alignment member 137, 137' can facilitate the alignment of the processing assembly 130, 130' relative to the base assembly 110, 110'. Because the closed position of the closure assembly 132, 132' is aligned relative to the alignment member 137, 137', the position of the closure assembly 132, 132' (even if the closure assembly 132, 132' is removed from the container 134, 134', respectively) can be aligned with the base assembly 110, 110', so that the engagement mechanism of the closure assembly 132, 132' can be operated to engage the base assembly 110, 110'.

[0152] In one embodiment, one or more ramp structures 139 of the container 134, in combination with one or more stops 146, can provide a plurality of closed positions for the closure assembly 132, wherein each closed position is aligned with the alignment feature 137 in the engaged position of the closure assembly 132 relative to the base assembly 110. For example, in the illustrated embodiment, three ramp structures 139 provide three starting positions for the closure assembly 132 to be screwed onto the container 134. Regardless of which starting position the closure assembly 132 engages, the closed position of the closure assembly 132 relative to the container 134 is ultimately aligned with the alignment feature 137 such that a) at least one position of the alignment feature 137 cooperates with the base assembly 110 to position the processing assembly 130 for engagement with the base assembly 110, and b) the closure assembly 132 is also positioned in this position for engagement with the base assembly 110. The ramp structure 139' of the processing assembly 130' can be configured in a similar manner.

[0153] In the illustrated embodiment, the stops 146 provided by the container 134 may be equally spaced relative to one another to substantially match the angular spacing α of the alignment members 137. Thus, there are multiple closed positions for the closure assembly 132 to engage the container 134. Regardless of whether there is more than one starting point for the closure assembly 132 to be screwed onto the container 134, and whether there is more than one closed position for the closure assembly 132, the spacing of the stops 146 relative to the alignment members 137 substantially ensures that each closed position aligns the closure assembly 132 relative to the alignment members 137 for engagement with the base assembly 110. In one embodiment, when the closure assembly 132 is in the closed position, not all of the alignment positions facilitated by the alignment members 137 correspond to closed positions to enable the closure assembly 132 to engage the base assembly 110; however, at least one of the alignment positions provided by the alignment members 137 relative to the base assembly 110 corresponds to a closed position. In one embodiment, each closure position available for closure assembly 132 is associated with an alignment position provided by alignment member 137 to ensure that closure assembly 132 can be mated to container 134 in a variety of ways, each providing alignment to engage processing assembly 130 to base assembly 110.

[0154] In the illustrated embodiment, the container 134 of the treatment assembly 130 includes a treatment assembly inlet 131 operable to receive untreated water from a water source. The treatment assembly inlet 131 can be operably coupled to the water inlet pipe 112 via the base assembly 110. The treatment assembly inlet 131 can be centered around the central axis 234 of the treatment assembly 130. In this way, no matter how the treatment assembly 130 rotates relative to the base assembly 110, the position of the treatment assembly inlet 131 can remain substantially the same. The treatment assembly inlet 131 can be operably coupled to a check valve 232, which prevents water from flowing back through the treatment assembly inlet 131, such as when the treatment assembly 130 is removed from the base assembly 110 for maintenance, the water remains in the container 134. In one embodiment, the treatment assembly inlet 131 can be operably coupled to a flow regulator to limit the flow rate, possibly to a maximum test value. The flow regulator can be integrated with the check valve 232. Fig.13 and Fig.15 The vessel 134' in the illustrated embodiment may be similarly configured with a central axis 234', a processing assembly inlet 131 ', and a check valve 232' arranged in a similar manner.

[0155] exist Figure 5-Figure 10 and Figures 11A-11H In the illustrated embodiment, the primary filter 150 (also described as a pre-filter) of the treatment assembly 130 can provide filtration for particles disposed in the untreated water received via the treatment assembly inlet 131. The water flowing through the primary filter 150 can be connected to a downstream filter, such as a filter assembly 170, which can operate to further treat the water that has passed through the primary filter 150. In one embodiment, the primary filter 150 can be configured to provide filtration for particles that, if not removed upstream of the filter assembly 170, may significantly reduce the useful life of the filter assembly 170. For example, the filter assembly 170 can be configured to filter particles that are considered fine or small for a target flow rate, and the primary filter 150 can be configured to filter particles that are considered large (e.g., 30 microns-500 microns) at the target flow rate. Without the primary filter 150, such larger particles may clog or reduce the effective filtration of the filter assembly 170 and its effective life. In one embodiment, the primary filter 150 can be configured to provide enhanced filtration aspects. For example, the primary filter 150 may include enhanced cleaning properties or be configured to filter selected contaminants (e.g., by the physical construction of the primary filter 150 or the type of filter media used in the primary filter 150). In one embodiment, the primary filter 150 may be absent from the filter bank 156, such as when the inlet water quality is deemed not to require the use of the primary filter 150.

[0156] Figure 8-Figure 10 The primary filter 150 in the illustrated embodiment includes an upper retainer 151 and a lower retainer 153 configured to support a primary filter medium 154 and define a primary filter opening 152. Optionally, one or both of the upper retainer 151 and the lower retainer 153 can form a seal against an outer surface of a filter assembly 170, wherein the filter assembly 170 is disposed within the primary filter opening 152 to substantially prevent untreated water entering the treatment assembly 130 from bypassing the primary filter 150 and passing directly to the filter assembly 170.

[0157] The filter assembly 170 is Figure 8-Figure 10 1 and 15. The illustrated embodiment is depicted in greater detail and can be seen disposed within and removed from opening 138 of container 134, and disposed within and removed from opening 152 of primary filter 150. Filter assembly 170 and primary filter 150 can filter untreated water received via treatment assembly inlet 131 into container 134, and discharge treated water via filter assembly outlet 172. Untreated water or water that has passed through primary filter 150 can enter filter media 171 of filter assembly 170.

[0158] The filter media 171 of the filter assembly 170 may include a carbon block filter that is operable to adsorb or filter (or both) particulates and contaminants contained in water such that water exiting the filter media 171 is considered filtered and ready for disinfection downstream through the UV reactor 380. In one embodiment, the filter media 171 may include a carbon block filter having an outer wrapper that provides support for the carbon block.

[0159] The filter assembly 170 may include an upper end cap 175 and a lower end cap 174, with the filter medium 171 disposed therebetween. The filter assembly 170 in the illustrated embodiment may be formed with an internal void 270 ( Fig.18 and Fig.21 In the illustrated embodiment, a cylindrical filter (shown as a cylindrical void) is defined internally and in fluid communication with the filter assembly outlet 172. The internal void 270 may not be cylindrical and may be configured differently. Water treated by the filter assembly 170 may be discharged to the filter assembly outlet 172 through the internal void 270.

[0160] In the illustrated embodiment, the lower end cap 174 is adhered or secured to the lower surface of the filter media 171 to seal the internal void 270 relative to the exterior of the filter assembly 170 such that untreated water passes through the filter media 171 of the filter assembly 170 before being discharged to the filter assembly outlet 172 via the internal void 270. The lower end cap 174 may include a plurality of spacer elements 176 extending radially from the central axis of the filter assembly 170, as described herein.

[0161] In combination Fig. 27 In one depicted embodiment, the filter assembly 170' can include a spacing element 176' that can facilitate centering or alignment of the filter assembly 170' within the opening 138' or void of the container 134'. The spacing element 176' can substantially align the central axis of the filter assembly 170' with the central axis of the container 134', thereby maintaining a space between the outer wall of the primary filter 150' (or the outer wall of the filter assembly 170') and the inner wall of the container 134', through which untreated water can flow and enter the filter medium 171'.

[0162] exist Figure 8-Figure 10 In the illustrated embodiment, the spacing element 176 (e.g., a spacer) can be configured to contact the bottom inner surface of the container 134 and define a gap between the lower end cap 174 and the bottom inner surface to enable water to flow from the treatment assembly inlet 131 through the space provided between the outer wall of the filter assembly 170 and the inner wall of the container 134. In this way, water can enter the container 134 via the treatment assembly inlet 131 and flow through the space, the primary filter 150, and then the filter media 171 to the interior void 270 of the filter assembly 170 to be discharged through the filter assembly outlet 172. In one embodiment, the lower end cap 174 can be formed of a rigid material to resist compression generated in response to engagement with the interior of the closure assembly 132 when the closure assembly 132 is rotated to fully engage the container 134. Resisting such compression can facilitate maintenance of one or more compression seals of the treatment assembly 130, as described herein.

[0163] In an alternative embodiment, lower end cap 174 may be formed of an elastomer that provides an upward spring pressure to promote sealing relative to upper end cap 175 and closure assembly 132. The elastomeric structure may optionally provide shock absorption to assist in handling and transferring hazards.

[0164] Similar to the lower end cap 174 and the lower surface of the filter medium 171, the upper end cap 175 can be adhered or fixed to the upper surface of the filter medium 171 to substantially prevent untreated water from entering the internal space between the lower end cap 174 and the upper end cap 175. It should be understood that the upper end cap 175 forms a watertight interface with another component (e.g., the closure assembly 132) to prevent untreated water from flowing into the internal space through the filter assembly outlet 172.

[0165] In the illustrated embodiment, the upper end cap 175 includes a sealing interface 173 or watertight interface that is configured to engage a sealing interface of the closure assembly 132. As discussed herein, the sealing interface 173 can substantially prevent untreated water from bypassing the filter assembly 170 and exiting through the closure assembly 132 without passing through the filter media 171.

[0166] Filter assembly 170' can be similar in many respects to filter assembly 170, including an upper end cap 175', a lower end cap 174', a filter assembly outlet 172', a filter medium 171', and an internal void 270', which are similar in many respects to upper end cap 175, lower end cap 174, filter assembly outlet 172, filter medium 171, and internal void 270 of filter assembly 170, respectively. For example, upper end cap 175' and lower end cap 174' can be respectively secured to upper and lower portions of filter medium 171', and define internal void 270, through which water treated by filter medium 171' can be discharged to filter assembly outlet 172'. This configuration of filter assembly 170' can be used in Figure 27-Figure 28 In the illustrated embodiment, it is seen that the filter assembly 170' includes a spacer element 176', which extends radially relative to the central axis of the filter assembly 170' and is configured to define a space between the lower end cap 174' and the lower surface of the container 134' to allow water to flow between the lower surface of the container 134' toward the peripheral surface of the filter medium 171'.

[0167] As described in further detail herein, the sealing interface member 173 of the filter assembly 170 is Fig.18 132, and is a radial seal. In the illustrated embodiment, the radial seal can be provided in the form of an O-ring, but the present invention is not limited thereto. The O-ring (e.g., a nitrile rubber O-ring or a nitrile O-ring, an EPDM rubber O-ring, a silicone O-ring or other types of O-ring materials) can be configured to provide a watertight seal in conjunction with the container interface 240 of the closure assembly 132, which defines a seal between a) water flowing into the treatment assembly 130 toward the primary filter medium 154 via the treatment assembly inlet 131 and b) water discharged from the filter assembly outlet 172 into the fluid receiving space 268 of the treatment assembly 130.

[0168] For example, in Figure 22-Figure 23 In an alternative embodiment shown in the illustrated embodiment, the filter assembly 170' may include a sealing interface 173' having an annular ridge extending from an upper surface of the upper end cap 175' that engages with a sealing interface of the closure assembly 132' to form a watertight seal. In one embodiment, the seal between the closure assembly 132' and the container 134' is provided by an interface between seals disposed on a convex detail of the tank interface portion of the closure assembly 132' that engages the interior of the container 134'. The annular ridge or the annular seal or both may be provided via a separate component that is operable to engage the upper surface of the upper end cap 175' and the closure assembly 132' to form a watertight seal.

[0169] exist Figure 5-Figure 10 and Figures 11A-11H In the illustrated embodiment, the primary filter 150 and the filter assembly 170 can form a filter group 156, wherein the filter assembly 170 is disposed within the primary filter opening 152 of the primary filter 150, which can define a gap extending within the primary filter medium 154 and between the upper retainer 151 and the lower retainer 153. The filter group 156 in the illustrated embodiment has no orientation requirements with respect to being disposed within the opening 138 of the container 134 (e.g., it can be rotated at any angle). The filter group 156 and the container 134 can facilitate embedded installation of the filter group 156 within the container 134. The filter assembly 170' can be similarly configured in conjunction with the primary filter 150' to allow installation within the container 134' without orientation requirements.

[0170] It should be understood that in one embodiment, the filter group 156 does not need to be replaced as a single entity during maintenance operations. Portions of the filter group 156 can be removed individually from the container 134 for maintenance. For example, the primary filter 150 can be removed independently or as an assembly with the filter assembly 170. The ability to remove the primary filter 150 independently can accommodate the generally shorter replacement period of the primary filter 150 relative to the replacement period of the filter assembly 170.

[0171] The processing assembly 130 in the illustrated embodiment includes a closure assembly 132 shown in various modes of use relative to a container 134, including Figure 5-Figure 6 The closed position and Figure 7134 and the filter assembly 170 are provided in a removal position for accessing the filter assembly 170 and the primary filter 150 disposed within the container 134. As described herein, the closure assembly 132 can close the opening 138 of the container 134, forming a watertight seal around the opening 138 of the container 134 and forming a watertight seal with the filter assembly 170 to enable treatment of water received via the treatment assembly inlet 131 without leakage of untreated water to the filter assembly outlet 172 through the seal formed between the closure assembly 132 and the sealing interface 173 of the filter assembly 170.

[0172] exist Figure 5-Figure 10 and Figures 11A-11H In the illustrated embodiment, the treatment assembly 130 can be removed from the base assembly 110 for maintenance. The treatment assembly 130 can form a pressure vessel that is operable to treat water received under pressure via the treatment assembly inlet 131 and discharge the treated water via the treatment assembly outlet 133 formed in the closure assembly 132. In one embodiment, the closure assembly 132 can engage a plurality of ramp structures 139 (e.g., three elements) arranged around the perimeter of the container 134 so that the treatment assembly 130 (or removable pressure vessel) can be closed or rotated one-third of a turn to reach a closed position. The plurality of ramp structures 139 provide a plurality of starting positions (e.g., three starting positions) for closing the container 134 with the closure assembly 132 to rotate the closure assembly 132 to the closed position.

[0173] In the illustrated embodiment, the handle assembly 136 of the closure assembly 132 is configured to provide a handle to twist the closure assembly 132 relative to the container 134 to disengage or reengage the plurality of ramp structures 139 of the container 134. In other words, the handle assembly 136 can facilitate rotation of the closure assembly 132 relative to the container 134 from a closed position to a removal position and enable access to the opening 138 of the container 134. The handle assembly 136 can also operate as a lifting point to carry the processing assembly 130 in a closed form as desired.

[0174] As discussed herein, removal of the closure assembly 132 from the container 134 can expose the filter bank 156, including the primary filter 150 and the filter assembly 170, which are nested in the opening 138 of the container 134 and stand on the bottom surface of the container 134. Optionally, the filter bank 156 can be accessed from above the upper edge of the container 134. In one embodiment, the upper portion of the filter bank 156 can be at least flush with the upper edge of the container 134 so that a large amount of water does not overflow from the container 134 when the closure assembly 132 is removed.

[0175] A. Container Components

[0176] According to one embodiment of the processing assembly 130, the container 134 is Fig.12 14. The container 134 includes an upper portion 142, a lower portion 141, and a plurality of alignment members 137 extending from the lower portion 141. As described herein, the container 134 includes a treatment assembly inlet 131 that is operable to form a watertight seal with the base assembly 110 to facilitate receipt of untreated water in the treatment assembly 130. The treatment assembly inlet 131 includes a water inlet coupling 231 configured to engage a water supply coupling 332 of the base assembly 110.

[0177] An alternative embodiment of the container is Fig.13 134' and is generally indicated by 134'. The container 134' includes an upper portion 142', a lower portion 141', and a plurality of alignment members 137' extending from the lower portion 141', which are respectively similar to the upper portion 142, the lower portion 141 and the alignment member 137 of the container 134. The container 134' also includes a treatment assembly inlet 131' that is similar to the treatment assembly inlet 131 in some aspects. The treatment assembly inlet 131' includes a water inlet coupling 231' configured to engage the water supply coupling 332' of the base assembly 110'. The container 134' may include a container seal 233', which is configured to cooperate with the water inlet coupling 231' to form a watertight seal with the water supply coupling 332' of the base assembly 110'. For the purpose of discussion, the container seal 233' is shown as being separated from the water inlet coupling 231' and in place relative to the water inlet coupling 231'.

[0178] exist Fig.13 In the illustrated embodiment, the container 134' includes a check valve 232' or a check regulator disposed in the flow path of the treatment assembly inlet 131'. For discussion purposes, the check valve 232' in the illustrated embodiment is shown separate from and positioned within the flow path of the treatment assembly inlet 131'.

[0179] As discussed herein, the alignment member 137' of the container 134' may include legs 143' and feet 145' operable to enhance alignment and stability relative to the base assembly 110'.

[0180] Figure 12-13 The container 134, 134' in the illustrated embodiment is shown having a ramp structure 139, 139' and a stop 146, 146' as described herein and disposed at the proximal end of the lower portion 142, 142'.

[0181] exist Fig.12 In the illustrated embodiment, the container 134 includes a check valve 232 or check regulator disposed in the flow path of the treatment assembly inlet 131 .

[0182] The container 134 according to one embodiment provides a modular configuration relative to its central axis 234. For example, in the illustrated embodiment, the container 134 includes three identical or substantially similar alignment members 137 that provide key aspects for positioning the processing assembly 130 relative to the base assembly 110. In this way, a user who removes the processing assembly 130 from the base assembly 110 for maintenance can easily find the correct position for alignment between the processing assembly 130 and the base assembly 110, thereby reducing the learning curve for maintenance, especially if maintenance is performed regularly over a period of several months. The alignment members 137' of the container 134' can be arranged in a similar manner relative to the central axis 234' of the container 134' and its lower portion 141'.

[0183] In one embodiment, the treatment assembly inlet 131 can be configured to limit or regulate the flow of water from the base assembly 110. Such regulation can substantially protect the filtering and disinfection components of the water treatment system 100. A flow regulator for the treatment assembly inlet 131 can be embedded in the water inlet coupling 231 (also described herein as a water inlet connector). In one embodiment, the check valve 232, 232' can operate as a flow regulator as well as a backflow preventer for the treatment assembly 130, 130'.

[0184] B. Closure components

[0185] The closure assembly 132 is Fig.14 and Figures 17A-17H The closure assembly 132 includes a handle assembly 136 that can be rotated between an operable position 261 and an engaged position 262 (also described herein as a stowed position), such as Figure 1E and Figure 17G The handle assembly 136 can facilitate engaging the processing assembly 130 to the base assembly 110 and removing the closure assembly 132 from the container 134 .

[0186] The closure assembly 132 in the illustrated embodiment includes a collar 242 (also described as a water tank collar) and a container interface 240 (also described as a water tank interface). The collar 242 and the container interface 240 may include corresponding supports 246, 247 (e.g., tabs or integral supports) having holes operable to receive a handle pin 248. The handle assembly 136 may include a closed hole 249 operable to rotatably couple to the supports 246, 247 in conjunction with the handle pin 248. In the illustrated embodiment, the handle pin 248 may slide through the hole or opening of the support 246 of the collar 242, through the hole 249 of the handle assembly 136, and through the hole of the support 247 of the container interface 240. The handle pin 248 can be sized to provide an interference fit relative to the holes of the supports 246, 247 while allowing free rotation about the surface of the handle pin 248 relative to the hole 249 of the handle assembly 136. In this way, the handle pin 248 and the handle assembly 136 can be fixed to the collar 242 and the container interface 240.

[0187] In the illustrated embodiment, the handle assembly 136 can include a releasable coupling 263 operable to latch or engage one or more components of the base assembly 110 to hold or maintain the treatment assembly 130 in position for use in conjunction with the base assembly 110, as described herein. The releasable coupling 263 can facilitate the formation of a watertight connection between the treatment assembly 130 and the base assembly 110, including a watertight connection between the treatment assembly inlet 131 and the water supply coupling 332 of the base assembly 110, and a watertight connection between the treatment assembly outlet 133 and the treated water inlet 362 of the base assembly 110.

[0188] The releasable connector 263 in the illustrated embodiment is integral with the handle assembly 136; however, it should be understood that the releasable connector 263 may be separate from the handle assembly 136 (e.g., incorporated into one or more aspects of the processing assembly 130 other than the handle assembly 136), or that multiple aspects or components of the releasable connector 263 may be incorporated into the handle assembly 136 and other aspects or components of the releasable connector 263 may form a part of the processing assembly 130 other than the handle assembly 136.

[0189] Fig.14 and Figures 17A-17HThe releasable coupling 263 in the illustrated embodiment includes an engagement member 271 that is coupled to the handle assembly 136 and operable to engage with the first catch 354 and the second catch 356 of the first base receiving portion 350 and the second base receiving portion 352 of the base assembly 110, respectively. As described herein, the first catch 354 and the second catch 356 can each provide: a) an opening that can receive the engagement member 271; and b) a retaining member that engages with the engagement member 271 to facilitate connection of the base assembly 110 with the processing assembly 130.

[0190] The closure assembly 132 of the illustrated embodiment further illustrates the engagement member 271 in detail, and the engagement member 271 is operable to pivot upward about the handle pin 248 in response to the rotation of the handle assembly 136 from the operable position 261 toward the engagement position 262. Each engagement member 271 can engage with the catch 354, 356 as the engagement member 271 rotates upward about the handle pin 248 and pulls the catch 354, 356 toward the handle assembly 136 in response to further rotation of the engagement member 271. When the handle assembly 136 is in the Figure 1E When in the illustrated engagement position 262, the engagement member 271 is positioned substantially vertically (or optionally rotated beyond vertical to form an acute angle relative to the top surface of the closure assembly 132) to substantially prevent lateral movement of the closure assembly 132 relative to the base assembly 110, thereby maintaining substantial alignment between the central axis 234 of the closure assembly 132 and the longitudinal axis of the base assembly 110.

[0191] The closure assembly 132 in the illustrated embodiment includes a first key element 255A and a second key element 255B that are operable to engage with a first receiving element 267A and a second receiving element 267B, respectively. The first key element 255A and the second key element 255B, in conjunction with the first receiving element 267A and the second receiving element 267B, provide alignment of the container interface 240 relative to the aperture 257 of the collar 242. In the illustrated embodiment, the first key element 255A and the first receiving element 267A are sized differently from the second key element 255B and the second receiving element 267B such that the collar 242 does not mate with the container interface 240. In other words, the first receiving element 267A may not receive the second key element 255B and / or the second receiving element 267B may not receive the first key element 255A.

[0192] In the illustrated embodiment, the closure assembly 132 includes a closure assembly registration element 147 that aligns with the first receiving element 267A and the second receiving element 267B. The closure assembly registration element 147 can be aligned with one or more registration elements 148 of the container 134 to provide a visual indication to the user that the closure assembly 132 and the container 134 are engaged.

[0193] exist Figure 15-16 The closure assembly 132' is shown in more detail in the depicted alternative embodiment. The closure assembly 132' can be similar to the closure assembly 132, but with several exceptions, including different configurations for the releasable coupling 263' to engage and disengage different coupling types with the base assembly 110'. The closure assembly 132' can include a handle assembly 136' that can facilitate engaging the processing assembly 130' to the base assembly 110' and removing the closure assembly 132' from the container 134'. The closure assembly 132' in the illustrated embodiment includes a collar 242' and a container interface member 240' having corresponding supports 246', 247', which may include a hole operable to receive a handle pin 248'. Similar to the handle assembly 136, the handle assembly 136' may include an orifice 249' that is operable to rotatably couple to the supports 246', 247' in conjunction with the handle pin 248'.

[0194] The handle assembly 136' of the closure assembly 132' may include a releasable coupling 263', which in the illustrated embodiment includes a tightening clip 251', a tightening pin 252', and a tightening spring 264' for each end of the handle assembly 136'. When the handle assembly 136' is rotated from the operable position 261' to the engaged position 262' (also referred to as the stowed position), the end of the tightening clip 251' away from the handle assembly 136' is operable to capture the base pin ( Figure 15-16 1 ). The tightening clamp 251 'can be rotatably coupled to the handle assembly 136' via the tightening pin 252' and the tightening pin hole 253' of the handle assembly 136'. When the handle assembly 136' is rotated from the operable position 261 'to the engaged position 262', the tightening clamp 251 'can contact the handle pin 248' beyond the center, push the handle assembly 136'into the engaged position 262', and provide tension on the distal end of the tightening clamp 251 'to substantially hold and engage the base pin of the base assembly 110', thereby holding the base assembly 110' and the processing assembly 130' in the engaged position.

[0195] To disengage the processing assembly 130' from the base assembly 110', the operator can rotate the handle assembly 136' from the engaged position 262' toward the operable position 261'. When the tightening pin 252' moves with the handle assembly 136' and releases the tension on the tightening clamp 251', the tightening clamp 251' moves laterally toward the base assembly 110' to facilitate the disengagement of the base pin. In addition, a tightening spring 264' is provided to urge the tightening clamp 251' to shift upward relative to the collar 242', thereby further enabling the tightening clamp 251' to leave the base pin of the base assembly 110' when the handle assembly 136' is further rotated toward the operable position. In the operable position, the handle assembly 136' is positioned so that the tightening clamp 251' leaves the base pin of the base assembly 110' and so that the closure assembly 132' can be moved laterally away from the base assembly 110'. With the tightening clip 251 ' clear of the base pin and the handle assembly 136' positioned in the operable position, the entire treatment assembly 130' may be tilted relative to the base assembly 110' for maintenance or removal from the base assembly 110'.

[0196] When the treatment assembly 130' is secured and properly engaged to the base assembly 110', the handle assembly 136' (also described as a tank closure handle) can be positioned in the engaged position 262' (also described as a stowed position or storage position). In one embodiment, the configuration of the handle assembly 136' and the releasable coupling 263' can only allow the installation of the treatment assembly 130' with the base assembly 110' to be completed when the treatment assembly 130' is sealed and deemed substantially safe. For example, if the closure assembly 132' is not in the closed position, the alignment between the alignment member 137' and the base assembly 110' may not produce an aligned position for the releasable coupling 263' to couple with the base assembly 110'.

[0197] As described herein, the releasable coupling 263' in the illustrated embodiment comprises a tightening clamp system. The over center action of the tightening clamp 251' can latch and secure the processing assembly 130' to the base assembly 110' or the frame assembly 313' (which is described herein as part of the base assembly 110'). In one embodiment, the tightening spring 264' is operable to raise the tightening clamp 251' to a disengaged position in response to the handle assembly 136' being raised to release the releasable coupling 263' (also described as an engagement mechanism). The handle assembly 136' can move forward or to the engagement position 262' to lower the tightening clamp 251' (also described as a spring clamp) to reengage the releasable coupling 263' to secure the processing assembly 130' to the base assembly 110'. The tightening clamp 251' may include a distal end relative to the handle assembly 136' with a hook that grasps or maintains a connection with a base component (e.g., base pins 351', 353' of the base assembly 110') under tension. In the absence of tension and the hook being disengaged from the base component, the tightening clamp 251' may allow the treatment assembly 130' to move freely relative to the base component.

[0198] exist Fig.55 In the depicted alternative embodiment, the releasable coupling 263 can be configured with a lever bolt system. For example, the handle assembly 136 can include an engagement element that rotates into a receiving feature on the frame assembly of the base assembly 110, which securely locks these assemblies together. Rotating the handle upward from its storage and fixed position can disengage the locking feature. In a more specific version of this example, the engagement element can include a hook that rotates to capture the receiving feature and converts the rotation of the handle assembly 136 into a linear movement to securely hold the processing assembly 130 and the base assembly 110 together. One or more elements (e.g., a latch) of the closure assembly 132 can substantially block or prevent the release of the hook after the hook has engaged the receiving feature. These one or more elements can enable the release of the hook in response to the force applied by the end user to disengage the hook.

[0199] exist Figure 56A-Figure 56E , Fig.57 and Fig.58In another alternative embodiment depicted in , the releasable coupling 263 can be configured with a lock top system. In this embodiment, the water treatment system 100 can include a closure cover that is mounted to the frame assembly and is operable to hinge downwardly to engage the water tank ring of the treatment assembly 130, thereby capturing the treatment assembly 130 and locking it securely in place to the base of its frame assembly. The handle assembly 136 of the closure assembly 132 can be configured to pivot or fold and can be positioned so that the closure cover can be properly positioned, which can substantially ensure proper engagement of the water passage of the assembly. In one embodiment, as described herein in conjunction with Figure 56A-Figure 56E , Fig.57 and Fig.58 The handling assembly described in the illustrated embodiment can be configured to substantially ensure proper positioning of the handling assembly relative to the base assembly for engagement, and to facilitate engagement of the closure cover with the tank ring to substantially prevent unlocking rotation without effort by the end user (e.g., a friction fit can prevent unlocking without force applied by the end user).

[0200] It should be noted that the ring feature or pivotable engagement structure 650 in combination with the locking head system can enable the treatment assembly 130 to be secured in a pressure-resistant manner in the event that the system attempts to break the watertight seal.

[0201] exist Fig.14 and Figures 17A-17H In the illustrated embodiment, the collar 242 includes a closure assembly stop 241 that is operable to engage the stop 146 of the container 134. The collar 242 can include one or more closure assembly ramps 266, the number of which corresponds to the number of the one or more ramp structures 139 of the container 134. As an example, the closure assembly ramps 266 and the ramp structures 139 of the container 134 can operate as a threaded coupling with one or more starting points, which facilitates converting the rotational motion of the collar 242 into linear motion and engaging the closure assembly 132 to the container 134. Figure 15-16 The alternative embodiment shown in Figure 1 including the closure assembly 132' also includes a collar 242' having a closure assembly stopper portion 241' operable to engage the stopper portion 146' of the container 134'. The closure assembly 132' may also include one or more ramps 266', the number of which corresponds to the number of the one or more ramp structures 139' of the container 134'.

[0202] Fig.14 and Figures 17A-17H The collar 242 in the illustrated embodiment includes an aperture 257 operable to receive an upper portion of the container interface 240 that is disposed within the container interface 240. Fig.14256 is shown in the illustrated embodiment generally designated upper portion 256. As discussed herein, upper portion 256 can include at least one key element 255A-255B configured to engage with at least one receiving element 267A-267B of aperture 257 to align container interface 240 with collar 242. Alignment between at least one key element 255A-255B and at least one receiving element 267A-267B can position treatment assembly outlet 133 relative to closure assembly stop 241 and releasable coupling 263 such that engagement of releasable coupling 263 causes treatment assembly outlet 133 to connect to base assembly inlet or treated water inlet 362 (in Fig.32D As described herein, the closure assembly stop 241 of the processing assembly 130 can correspond to the alignment member 137 of the processing assembly 130. At least one of the closure assembly stop 241 and the alignment member 137 can correspond to a position of the releasable coupling 263 that is operable to engage the base assembly 110 to connect the processing assembly outlet 133 to the base assembly 110.

[0203] exist Figure 15-16 In the illustrated alternative embodiment, the closure assembly 132' can be configured in a similar manner to the closure assembly 132 with an aperture 257' provided by the collar 242' and an upper portion 256' of the container interface 240' including a key element 255' and the collar 242' including a receiving element 267'. In the illustrated embodiment, the container interface 240' includes a plurality of alignment pins 254' that are configured to align with the alignment apertures 258' provided in the collar 242'. The alignment pins 254' can provide further stability regarding the positioning of the collar 242' relative to the container interface 240', potentially relieving some of the rotational stress on the key element 255' and the receiving portion in response to rotation of the closure assembly 132' relative to the container 134'.

[0204] exist Fig.14 and Figures 17A-17H In the illustrated embodiment, the closure assembly 132 includes an interface seal 243, such as a C-shaped seal (e.g., a C-seal or a C-ring seal) or an O-ring. The interface seal 243 can be made of a variety of materials depending on the application, including, for example, nitrile rubber or nitrile rubber, EPDM rubber, silicone or other types of sealing materials. The interface seal 243 can be operated to promote providing a watertight seal between the closure assembly 132 and the container 134 in response to the closure assembly 132 rotating to a closed position relative to the container 134. The interface seal 243 can be located in a groove 245 of the container interface 240. The interface seal 243 (e.g., a closure seal) can form a seal between the container interface 240 and the inside of the container 134.

[0205] exist Fig.15 and Fig.16 In the illustrated embodiment, the closure assembly 132' can include an interface seal 243' that is operable to provide a similar seal between the closure assembly 132' and the container 134' and can be formed of materials similar to those described in conjunction with the interface seal 243. The interface seal 243' can be at least partially disposed within the groove 245' of the container interface 240'.

[0206] Fig.14 , Figures 17A-17H and Figure 15-16 The container interface 240, 240' in the illustrated embodiment includes a spiral or helical flow path 269, 269' within the fluid receiving space 268, 268' of the container interface 240, 240', which can be positioned to be in fluid communication with the filter assembly outlet 172, 172'. The flow path 269, 269' can facilitate the water received by the fluid receiving space 268, 268' toward the internal water receiver 260, 260' in fluid communication with the treatment assembly outlet 133, 133'. The spiral or helical configuration can facilitate the collection and discharge of air within the fluid receiving space 268, 268' to the base assembly 110. It should be understood that the flow path 269, 269' may not exist or be configured to be different from the spiral or helical flow configuration depicted in the illustrated embodiment. For example, the flow path 269, 269' can be truncated relative to its configuration in the illustrated embodiment without having a spiral or helical flow configuration.

[0207] In one embodiment, the treatment assembly outlet 133, 133' (also described as a water outlet feature) provided by the closure assembly 132, 132' is located at the highest point of the treatment assembly 130, 130' to substantially minimize or reduce water spillage when the treatment assembly 130, 130' is detached from the base assembly 110, 110' in preparation for removal or during and after the treatment assembly 130, 130' is removed from the base assembly 110, 110'. The treatment assembly 130, 130' can define an end of an ascending spiral flow channel 269, 269' (the ascending spiral portion of which can be considered optional) that is configured to facilitate the collection and removal of air accumulated in the treatment assembly 130, 130', thereby substantially ensuring complete emptying of the treatment assembly 130, 130' in an effort to prevent undesirable pressurization. It should be noted that pressurization of the treatment assembly 130, 130' due to the presence of air may cause the water treatment system 100, 100' to continue to allow water to flow even after the water supply has ceased.

[0208] The one or more compression seals mounted on the male feature of the treated water inlet 362 of the frame assembly 313 may be conical to ensure engagement and proper concentric positioning with the receiving feature of the treatment assembly outlet 133, 133' of the closure assembly 132, 132'.

[0209] C. Filter components

[0210] The filter assembly 170 in one embodiment of the present invention is Fig.12 , Fig.21 , Fig.24 , Figure 25A-25B and Figure 26A-26D The filter assembly 170 includes a filter assembly 170 that ... Fig.10 The upper and lower end caps 175, 174 and filter media 171 of the illustrated embodiment are shown. The filter assembly 170 of the illustrated embodiment also includes an internal void 270, a filter assembly outlet 172 and a spacing element 176. It can be seen that the sealing interface 173 is connected to the Fig.18 The closure assembly 132 in the illustrated embodiment engages to form a watertight seal between the filter assembly outlet 172 and untreated water passing through the filter assembly 170 to the internal void 270 and through the filter assembly outlet 172 to the treatment assembly outlet 133 .

[0211] In one embodiment, filter media 171 may include activated carbon. Filter media 171 may include performance modifiers and structural elements to achieve a target mechanical shape and strength.

[0212] The filter assembly 170 in the illustrated embodiment is operable to provide filtration by affecting a water path that is introduced through the outer surface of a formed media (e.g., filter media 171), passes through an open interior chamber (e.g., internal void 270) leading to an outlet path or filter assembly outlet 172, and retains contaminants in or on the consumable and replaceable filter media 171.

[0213] In one embodiment, the cover structure on the "closed" bottom end is provided as a lower end cap 174 that substantially closes and seals the interior chamber (e.g., the interior void 270). A spacing element 176 extending from the lower end cap 174 can be configured to space the filter assembly 170 from the container wall of the container 134 to provide a substantially consistent and managed water path to the outer surface of the filter medium 171.

[0214] exist Figure 27-Figure 28In an alternative embodiment of the invention, a filter assembly similar to filter assembly 170 and generally designated 170' is shown. Filter assembly 170' may include filter media 171', lower end cap 174', and upper end cap 175' having filter assembly outlet 172'. Upper end cap 175' may include a sealing interface 173' similar to sealing interface 173 described herein in conjunction with filter assembly 170, except that sealing interface 173' is disposed on an upper surface of upper end cap 175' and may function as an annular compression seal.

[0215] Figure 27-Figure 28 The lower end cap 174' in the illustrated embodiment can be partially or completely formed of an elastic material that is capable of flexing to some extent under pressure but resists such flexing. In one embodiment, the elastomeric features or aspects of the lower end cap 174' can provide mechanical pressure (e.g., under compression) to make a watertight seal between the opposing discharge end cap or upper end cap 175' and the closure assembly 132'. Additionally or alternatively, the elastic material can enable the filter assembly to respond to shock, thereby substantially protecting the filter media 171' from damage during transportation or in the event of product abuse.

[0216] exist Fig.18 , Fig.21 , Fig.24 , Figure 25A-25B and Figure 26A-26D In the illustrated embodiment, the lower end cap 174 includes a plurality of spacer elements 176, which, along with the remainder of the lower end cap 174, can be substantially rigid to resist deflection under pressure. The spacer elements 176 can maintain the space between the lower surface of the container 134 and the lower end cap 174 and the position of the upper end cap 175 relative to the container 134. The lower end cap 174 in the illustrated embodiment includes a plurality of concentric rings 177 that protrude from the surface of the lower end cap 174 and engage the filter media 171. The concentric rings 177 can increase the available surface area for bonding to the filter media 171 relative to an alternative configuration in which the concentric rings 177 are not present on the surface of the lower end cap 174 and the filter media 171 is bonded to the surface.

[0217] The discharge end of filter assembly 170 (or upper end cap 175 with filter assembly outlet 172 ) is operable to separate the influent water flow directed to the exterior media surface of filter media 171 from the discharge flow exiting the interior chamber (interior void 270 ) and discharged from filter assembly outlet 172 .

[0218] In the illustrated embodiment, the central drain of the upper end cap 175 may include a non-replicable identifier, and in one embodiment may be provided by a programmable radio frequency identification (RFID) electronic component or RFID component 272. The RFID component 272 may be disposed on the filter assembly 170 in a variety of locations and is not limited to being included on the central drain. The RFID component 272 may facilitate the water treatment system 100 to identify the filter assembly 170. In one embodiment, the water treatment system 100 may track the use of the filter assembly 170 and confirm that the filter assembly 170 is the appropriate type of filter assembly for the water treatment system 100. The water treatment system 100 may be operable to transmit information to the RFID component 272 of the filter assembly 170, including, for example, to store usage information. In this way, even if the filter assembly 170 is removed and replaced in the treatment assembly 130, an attempt to reuse the filter assembly 170 may still be identified.

[0219] The upper end cap 175 in the illustrated embodiment may include an end cap RFID cover 273 operable to hold an RFID component 272 in place relative to the filter assembly outlet 172, and the end cap RFID cover 273 may include an internal cavity 274 in which the RFID component 272 may be disposed. The upper end cap 175 in the illustrated embodiment may also include a plurality of fluid pathways 275 through which water may flow from the internal void 270 to an area outside the filter assembly 170. In one embodiment, an ultrasonic weld may be provided between the filter assembly outlet 172 (e.g., the end cap RFID base) and the end cap RFID cover 273 to form a watertight cavity encapsulating the RFID component 272 (e.g., an RFID tag).

[0220] In the illustrated embodiment, the RFID component 272 can be positioned relative to the longitudinal axis of the upper end cap 175 and the filter assembly 170 so that the RFID component 272 remains close to the longitudinal axis even if the filter assembly 170 is rotated about the longitudinal axis. In one embodiment, the filter assembly 170 can be installed or arranged in the processing assembly 130 without regard to the orientation of the filter assembly 170. Regardless of the orientation of the filter assembly 170 in the processing assembly 130, when the processing assembly 130 is connected to the base assembly 110, the RFID component 272 can be aligned to communicate with the wireless communication circuit 390 of the base assembly 110. In this way, wireless communication can be provided without the user having to consider the alignment and / or orientation of the filter assembly 170 in the processing assembly 130. In addition, the processing assembly 130 and the filter assembly 170 can be free of registration marks, alignment guides, orientation guides, or a combination thereof, thereby potentially saving costs and reducing manufacturing complexity.

[0221] In the illustrated embodiment, the filter assembly 170 includes a filter handle 277 that can be stowed to a flat position and rotated to a generally vertical operative position to enable a user to pull the filter handle 277 to remove the filter assembly 170 from the container 134. The filter handle 277 can be coupled to the upper end cap 175 in a variety of ways, depending on the application.

[0222] In the illustrated embodiment, the filter handle 277 can be coupled to the upper end cap 175 according to one or more of the following steps. The filter handle 277 can include first and second outer supports 279A-279B that can be inserted into first and second end cap holes 278A-278B, which can be formed by openings in tabs extending from the outer surface of the upper end cap 175. The filter handle 277 can be sufficiently flexible to allow the first and second outer supports 279A-279B to be squeezed toward each other and then released to be inserted outwardly into the first and second end cap holes 278A-278B. The filter assembly outlet 172 can include first and second retainers 276 that are operable to capture the first and second inner supports 280A-280B of the filter handle 277. After the first and second outer supports 279A-279B are inserted into the first and second end cap holes 278A-278B, the filter assembly outlet 172 can be arranged so that it contacts the outer surface of the upper end cap 175 and the first and second retaining members 276 capture the first and second inner supports 280A-280B. The filter assembly outlet 172 can be fixed to the upper end cap 175 in this position, for example, by ultrasonic welding. In this embodiment, after the filter assembly outlet 172 is fixed to the upper end cap 175, the filter handle 277 can be trapped while still being rotatable between the stowed position and the operable position. More specifically, the first and second outer supports 279A-279B and the first and second inner supports 280A-280B can be trapped by the first and second end cap holes 278A-278B and the first and second retaining members 276 of the filter assembly outlet 172, respectively.

[0223] As described herein, the upper end cap 175 in the illustrated embodiment may include a sealing interface 173. The sealing interface 173 may be a peripheral O-ring type seal, and its material type may be one or more of the types described in conjunction with the interface seal 243. The upper end cap 175 in the illustrated embodiment includes an upper end cap groove 281 operable to receive the sealing interface 173, as described herein, which may form a fluid-tight seal with the inner surface of the container interface 240, as described herein. Fig.18 and Fig.21 As depicted in the illustrated embodiment.

[0224] exist Figure 22-Figure 23 and Fig. 27 In the illustrated alternative embodiment, the upper end cap 175' can be partially or completely formed of an elastomeric material capable of forming a watertight seal with the closure assembly 132'. For example, the sealing interface member 173' can be formed of an elastomeric material or a material capable of forming a watertight seal under load in conjunction with the closure assembly 132'. In response to the closure assembly 132' being positioned in the closed position, the sealing interface member 173' can engage the inner surface of the closure assembly 132' (which defines the internal receiving space of the closure assembly 132'). In one embodiment, the elastomeric properties of the lower end cap 174' combined with the elastomeric properties of the upper end cap 175' can deform at the interface with the container 134' and the closure assembly 132', but promote the formation of a watertight seal between the untreated water entering the treatment assembly 130' and the water discharged from the filter assembly outlet 172'.

[0227] In one embodiment, the primary filter 150 is configured to provide a cylinder formed of active media, which is capped by a structure (e.g., an upper retainer 151 and a lower retainer 153) that substantially maintains the shape of the primary filter 150 and serves to protect the thin edges of the media material (e.g., the primary filter media 154). The edges of the media material can be considered to be thin relative to the thickness of the filter media 171 of the filter assembly 170.

[0228] In the illustrated embodiment, the primary filter media 154 provides an active media including fiber filtration to address large particle rejection, or provides a material encapsulating an active chemical designed to target specific water contents.

The upper wipe seal 157 and the lower wipe seal 158 can be configured so that when the filter assembly 170 is pushed from the upper retainer 151 through the primary filter opening 152 of the primary filter 150 and arranged in a seated position relative to the lower retainer 153, the upper wipe seal 157 and the lower wipe seal 158 form their respective seals. The upper wipe seal 157 and the lower wipe seal 158 can be integral with the upper retainer 151 and the lower retainer 153.

[0230] The primary filter 150 in the illustrated embodiment includes a plurality of primary filter spacers 159 extending from the lower retainer 153. The primary filter spacers 159 can facilitate alignment of the filter stack 156 within the interior space of the container 134, including, for example, to substantially maintain a fluid path between the filter stack 156 and the interior surface of the container 134 for water to flow from the treatment assembly inlet 131 to the interior void 270 of the filter assembly 170.

The treated water inlet 362 may include a treatment assembly connector that is conically shaped to engage a corresponding tapered surface of the treatment assembly outlet 133. This configuration may facilitate alignment of the treated water inlet 362 with the treatment assembly outlet 133 and form a watertight connection in response to engagement of the releasable coupling 263 with the base assembly 110. The treated water inlet 362 of the base assembly 110 may be in fluid communication with a UV reactor fluid channel 360 that provides water for the UV reactor 380 to be discharged from the treatment assembly 130 to the treated water inlet 362. Fig.38 and Figure 40-41 The base assembly 110' in the illustrated embodiment may include a treated water inlet 362' configured in a similar manner to engage or connect with the treatment assembly outlet 133' and direct water through the UV reactor fluid passage 360'.

In the illustrated embodiment, the number of base assembly receiving portions 342 may correspond to the number of alignment members 137 extending from the processing assembly 130. Thus, the base assembly receiving portions 342 may be configured to correspond to the number of alignment members 137 extending from the processing assembly 130. Fig.11H The angles α described in the illustrated embodiment are equally spaced from each other around the central axis. In this way, the processing assembly receiving portion 340 can receive the alignment member 137 of the processing assembly 130 in multiple positions, which can correspond to the number of alignment members 137. The base assembly receiving portion 342 can facilitate the alignment of the closure assembly 132 relative to the first and second base receiving portions 350, 352 by receiving multiple alignment members 137. As an example, in the illustrated embodiment, at least one of the multiple positions that can be used for alignment between the base assembly receiving portion 342 and the alignment member 137 can correspond to an engagement position that facilitates engagement between the releasable coupling 263 of the closure assembly 132 and the first and second base receiving portions 350, 352. The base assembly 110' can be configured in a similar manner, wherein the processing assembly receiving portion 340' includes a plurality of base assembly receiving portions 342', each of which is respectively configured to receive or receive the alignment member 137' of the processing assembly 130'.

[0253] As described herein, the treatment assembly 130 can be effectively disengaged from the first and second base receiving portions 350, 352 and pivoted to an inclined position relative to the frame assembly 313. The inclined position can facilitate maintenance of the treatment assembly 130 without having to substantially vertically move the treatment assembly 130 relative to a horizontal surface on which the water treatment system 100 is positioned for use. Extensive use of the head space above the upper portion 102 can be avoided during maintenance operations of the treatment assembly 130, such that the water treatment system 100 can be positioned to use little such head space. In the inclined position, in an alternative embodiment, the treatment assembly 130' can be supported by the distal end of the treatment assembly receiving portion 340' and / or the first and second base pins 351', 353' in conjunction with the tightening clip 251'.

[0254] exist Figure 18-Figure 21 , Fig.31 , Figure 32A-32H and Figure 33-Figure 37 In the illustrated embodiment, the water supply coupling 332 may be supported by the connector support 330 of the base assembly 110. The connector support 330 may be supported at least at Fig.18 , Fig.21 , Fig.31 , Fig.32C and Fig.37 The connector support 330 is operable to allow the water supply coupling 332 to pivot relative to the treatment assembly receiving portion 340, thereby enabling the treatment assembly 130 to pivot or tilt outwardly relative to the frame assembly 313 while remaining supported by the water supply coupling 332. Fig.21 The connector support 330 depicted in FIG. 1 is configured such that the central axis 234 of the processing assembly 130 can be pivoted through an angle Φ from a generally upright vertical position to a tilted position.

[0255] The treatment assembly receiver 340 may include a rear support surface 393 and a front support surface 394 adapted to hold the lower portion 141 of the treatment assembly 130 in an engaged position and a tilted position, respectively (e.g., a position in which the treatment assembly is pivoted outward when the handle assembly 136 is in the operable position 261). The base assembly 110 may include a base member 391 having an engagement surface 392 operable to cooperate with the rear support surface 393 to maintain a position of the treatment assembly 130 along the central axis 234 of the treatment assembly 130. In one embodiment, the engagement surface 392 and the rear support surface 393 of the base member 391 may operate a C-clip to maintain a longitudinal position of the treatment assembly 130 relative to the base assembly 110, whereby the first and second base receivers 350, 352, if engaged by the handle assembly 136, maintain a lateral position of the treatment assembly 130 relative to the base assembly 110. In the illustrated embodiment, the base member 391 includes the first base receiving portion 350 and the second base receiving portion 352 and includes a cavity that accommodates the wireless communication circuit 390, which is operable to communicate with the RFID component 272 of the filter assembly 170. The engagement surface 392 of the base member 391 can contact the closure component 132 of the processing assembly 130 to apply a downward force on the processing assembly 130, and the rear support surface 393 can apply an upward force to the lower portion 141 of the processing assembly 130.

[0256] In the illustrated embodiment, the rear support surface 393 that contacts the lower portion 141 of the processing assembly 130 while being engaged to the base assembly 110 may roughly correspond to the rear half (e.g., 180°) of the processing assembly receiving portion 340, and the front support surface 394 may roughly correspond to the front half (e.g., 180°) of the processing assembly receiving portion 340.

[0257] The connector support 330 in the illustrated embodiment includes an inlet elbow 372 that defines a water supply inlet 334 and is configured to be inserted into a receiving space of the treatment component connector 374. The inlet elbow 372 may include a peripheral recess that is configured to receive a seal 378 to form a watertight seal with the inner surface of the receiving space of the treatment component connector 374. The seal 378 may be configured to allow the inlet elbow 372 to rotate relative to the treatment component connector 374, thereby allowing the water inlet pipe 112 to be positioned according to the location of the water source. For example, the inlet elbow 372 can be rotated from the treatment component connector 374. Fig.31 The rearward facing position shown is rotated to a forward facing position to accommodate the water inlet tube 112 disposed near the front of the water treatment system 100 .

[0258] The inlet elbow 372 may include a peripheral ridge 375 operable to engage with a retainer 373, wherein the inlet elbow 372 is inserted into a receiving space of the processing assembly connector 374. The retainer 373, in combination with the peripheral ridge 375, may prevent the inlet elbow 372 from being removed from the receiving space of the processing assembly connector 374. For example, when the inlet elbow 372 and the processing assembly connector 374 are under pressure, the retainer 373 may prevent the inlet elbow 372 from being ejected from the receiving space.

[0259] In one embodiment, the installation of the retainer 373 can prevent the removal of the treatment assembly connector 374 from the connector support 330 without restricting the rotation of the treatment assembly connector 374 within the connector support 330. The installation method according to one embodiment can include inserting the treatment assembly connector 374 into the receiving space of the connector support 330, wherein the protrusion 371 (e.g., a nub) of the treatment assembly connector 374 is aligned with the recess 376 or opening in the wall of the receiving space of the connector support 330. The inlet elbow 372 can be inserted into the receiving space of the treatment assembly connector 374 so that the protrusion 371 slides within the recess 376. The retainer 373 can then be installed onto the inlet elbow 372 via the receiving space of the connector support 330, holding the inlet elbow 372 in place and holding the protrusion 371 in place relative to the recess 376. The protrusion 371 and the recess 376 may enable the processing assembly connector 374 to pivot within the connector support 330 but not be removed from the connector support 330 .

[0260] In the illustrated embodiment, treatment assembly connection 374 includes a container seal 233 (eg, an O-ring) operable to form a seal with an interior surface of treatment assembly inlet 131 to prevent leakage of water under pressure.

[0261] As discussed herein, the treatment assembly connector 374 can pivot within the connector support 330. As an example, the treatment assembly connector 374 can pivot between a generally upright vertical position and a tilted position at an angle Φ, and can support the treatment assembly 130 within this angular range. In or near the vertical position, the handle assembly 136 of the treatment assembly 130 can be transitioned from the operable position 261 to the engaged position 262, such that the first and second catches 354, 356 are engaged by the first and second engagement members 271, thereby substantially maintaining the lateral position of the treatment assembly 130 relative to the base assembly 110.

[0262] exist Fig.38 and Figure 40-41 In the depicted alternative embodiment, the base assembly 110' can include a water supply coupling 332' that can be supported within an opening 335' of the connector support 330'. The connector support 330' can include a ring defining the opening 335', ​​the ring having a ledge 339' that supports a lip 341' of the water supply coupling 332' such that the water supply coupling 332' is retained within the opening 335' of the connector support 330'. Fig. 22 This construction can be seen in more detail in the illustrated embodiment. Fig.38 and Figure 40-41 In the illustrated embodiment, the connector support 330' includes first and second protrusions 331' disposed on opposite sides of the connector support 330'. The first and second protrusions 331' can be coupled to the connector support 330' within the opening 335' of the treatment assembly receiving portion 340' and positioned within the first and second support recesses 333' of the treatment assembly receiving portion 340'. The positioning of the first and second protrusions 331' and the ring of the connector support 330' within the opening 335' can enable the connector support 330' to pivot about the first and second support recesses 333'. In the illustrated embodiment, the water supply coupling 332' can also pivot in conjunction with the connector support 330' when positioned on the ledge 339' of the connector support 330'. The pivoting ability of the connector support 330' and the water supply coupling 332' can enable the treatment assembly 130' to pivot even when the water inlet coupling 231' is connected to the water supply coupling 332'.

[0263] In one embodiment, the diameter of the opening for the water supply coupler 332' to receive the water inlet coupler 231' can be effectively sized to enable a user to push the water inlet coupler 231' to engage with the water supply coupler 332' at an angle or in an inclined position and then pivot the entire treatment assembly 130' toward the engaged position. The pivoting action of the treatment assembly 130' can be performed in part by engaging the tightening clamp 251' with the first and second base pins 351', 353' and rotating the handle assembly 136' from the operable position 261' to the engaged position 262'. In one embodiment, the water supply coupler 332' in combination with the connector support 330' can serve as an interception feature of the water inlet coupler 231' of the treatment assembly 130' and provide a substantially stable base to orient and position the treatment assembly 130' along its installation or engagement path.

[0264] One aspect of the water supply coupling 332' is a) seating capability that provides a mating seal to an interface feature of the treatment assembly 130' (e.g., to the water inlet coupling 231' of the treatment assembly 130'), and b) rotation capability that matches the entry angle of the water tank to ensure alignment of the sealed connection and maintain the connection as the water tank moves.

[0265] In one embodiment, the water supply coupling 332' (also described as an interface assembly) can be rotated to align with a connecting plumbing line below the water treatment system 100'.

[0266] In one embodiment, the water supply coupling 332' may include a recess that engages a lip extending from a ledge 339' of the connector support 330', such as Fig. 22330', such that the water supply coupling 332' remains engaged with the connector support 330', regardless of the axial force applied to the water supply coupling 332' in response to the removal of the water inlet coupling 231' from the water supply coupling 332'. Additionally or alternatively, the first and second protrusions 331' of the connector support 330' may be at least partially captured by the first and second support recesses 333' of the treatment assembly receiving portion 340', thereby substantially maintaining the connector support 330' in place, regardless of the force applied to the water supply coupling 332' in response to the removal of the water inlet coupling 231' from the water supply coupling 332'. The first and second protrusions 331' can be faceted so that rotation of the connector support 330' beyond its normal rotational path for installation and removal of the processing assembly 130' enables the first and second protrusions 331' to exit the openings provided by the first and second bearing recesses 333'. This removal aspect of the first and second protrusions 331' enables the connector support 330' to be removed from the base assembly 110'. In one embodiment, the connector support 330' can be mounted in a feature of the frame assembly 313' (e.g., a frame base) that locks the connector support 330' to resist extraction when required to resist an axial force that is required to disengage it in order to remove the processing assembly 130'.

[0267] exist Figure 18-Figure 21 , Fig.31 , Figure 32A-32H and Figure 33-Figure 37 In the illustrated embodiment, internal components of the base assembly 110 mounted on the frame assembly 313, such as the water treatment and electrical unit components, can be covered by a rear cover assembly (e.g., cover 310) which can provide an aesthetic look and feel, potentially protect the internal components, and accommodate a light-conducting structure that provides an indication of system health as an extension of the display unit 314.

[0268] The base 105 (eg, a base pedestal portion) may be secured to the unit body assembly to provide aesthetically pleasing conduit management, and a stable, structural, or protective containment to assist in the desired positioning arrangement.

[0269] Steering Figure 33-Figure 3710. The embodiment shown in FIG. 10 shows the components of the base assembly 110 in more detail. As discussed herein, the internal components may include a display unit 314, a control system 318, a sensor unit 316, and a UV reactor 380. In the embodiment shown, the UV reactor 380 includes a UV reactor inlet 382, ​​which is configured to be in fluid communication with the UV reactor fluid channel 360 to receive water discharged from the treatment assembly 130. The UV reactor 380 is operable to supply UV energy to the water received via the UV reactor inlet 382, ​​thereby disinfecting the water. The disinfected water can be discharged or output via the UV reactor outlet 384 and directed to the treated water outlet 364. The UV reactor inlet 382, ​​the UV reactor outlet 384, and the UV fluid channel 360 may include connectors that are spin-welded to attach to their respective mating components to form a sealed connection.

[0270] Fig.40 , including a display unit 314', a control system 318', a sensor unit 316', and a UV reactor 380' that are similar in many functional aspects to the display unit 314, the control system 318, the sensor unit 316, and the UV reactor 380. In addition, in the base assembly 110', the UV reactor 380' includes a UV reactor inlet 382' in fluid communication with the UV reactor fluid channel 360' to receive water discharged from the treatment assembly 130'. The sterilized water can be discharged from the UV reactor 380' via the UV reactor outlet 384', which is in fluid communication with the sensor unit inlet 385 of the sensor unit 316.

[0271] Alternatively, as described herein, the sensor unit 316 may be disposed in another portion of the fluid flow path of the water. For example, the sensor unit 316 may be disposed to receive water discharged from the treatment assembly 130 and output the water to the UV reactor inlet 382.

[0272] exist Figure 18-Figure 21 , Fig.31 , Figure 32A-32H and Figure 33-Figure 37 In the illustrated embodiment, the base assembly 110 can include an RFID communicator or wireless communication circuit 390 that is capable of wirelessly communicating with one or more components external to the base assembly 110. As an example, the wireless communication circuit 390 can communicate with an RFID component 272 (e.g., an RFID tag) provided in the filter assembly 170. As mentioned herein, the wireless communication circuit 390 can potentially be supported within and by the base member 391. The RFID component 272 of the filter assembly 170 can be disposed adjacent to the wireless communication circuit 390.

[0273] In one embodiment, the internal components of water treatment system 100 may include an electrical and control system arranged around the waterway system of frame assembly 313. The electrical and control system may include a display unit 314 that is secured to frame assembly 313 near the front side of water treatment system 100 so that the information features of display unit 314 are visible to a user at the installation location of water treatment system 100. In the illustrated embodiment, display unit 314 may be connected to control system 318 via a detachable tether 317.

[0274] In one embodiment, wireless communication circuit 390 may include RFID antenna 395 attached to frame assembly 313 and supported by base member 391. When processing assembly 130 is in the installed position, RFID antenna 395 of wireless communication circuit 390 may be arranged near processing assembly 130, such as Fig.21 The wireless communication circuit 390 can be connected to the display unit 314 via one or more removable or fixed tethers 319. Additionally or alternatively, the wireless communication circuit 390 can be directly connected to the control system 318 or connected via the tether 319 or another component of the water treatment system 100 (e.g., a control board).

[0275] The electrical and control system is not limited to the system described in conjunction with the illustrated embodiment of the water treatment system 100; it should be understood that the electrical control system can be updated, replaced, or substituted with other technical systems as determined independently of the other system components. For example, an alternative electrical and control system for a portion of the base assembly 110' may be provided in Fig.40 In the illustrated embodiment, similar components to the base assembly 110 are shown with similar reference numerals but with the addition of a "'" (prime) identifier.

[0276] Waterway components of the base assembly 110 (eg, the sensor unit 316 and the UV reactor 380 ) may be arranged and fixed to the frame assembly 313 .

[0277] In the illustrated embodiment, the waterway is received from the treatment assembly 130 through a top member (e.g., a treated water inlet 362), which is fixed to the frame assembly 313, placed in alignment and structurally supporting mechanical forces to connect and seal the channel under flow and pressure conditions. The treated water inlet 362 can be fluidly coupled to the UV reactor fluid channel 360 to deliver water to the UV reactor 380 via the UV reactor inlet 382. The UV reactor 380 can be operable to receive power and control from the control system 318 to operate the disinfection process. The sensor unit 316 in the illustrated embodiment is disposed in the UV reactor fluid channel 360; however, the present invention is not limited thereto. The sensor unit 316 can be arranged to obtain sensor information about any fluid path of the water treatment system 100, or obtain sensor information about any aspect of the water treatment system 100, or a combination thereof.

[0278] For example, in Fig.40 In the illustrated embodiment, the UV reactor 380' and the sensor unit 316 are arranged such that the UV reactor 380' can discharge sterilized water to the sensor unit 316 for delivery to a point of use. Fig.40 The sensor unit 316' in the illustrated embodiment is operable to receive water discharged from the UV reactor 380' via the sensor unit inlet 385' and discharge the water to the treated water outlet 364' which serves as the outlet of the water treatment system 100'. In other words, the sensor unit 316' can be integrated with the outlet connection of the water treatment system 100' in the illustrated embodiment and form the end of the water path. Alternatively, the sensor unit 316' can discharge the water to another fluid path component so that the water is ultimately discharged from the water treatment system 100' to an outlet in fluid communication with the point of use.

[0279] exist Figure 33-Figure 37 In the illustrated embodiment, the sensor unit 316 may be disposed in the fluid path where the water is treated and before the UV reactor 380. Alternatively or additionally, the sensor unit 316 may be disposed before one or more other components that discharge the water upstream of an outlet at the point of use.

[0280] The sensor unit 316 may monitor and measure the water flow. Additionally or alternatively, the sensor unit 316 may measure the water temperature or another property of the water.

In the illustrated embodiment, the wireless communication circuit 390 is connected to the display unit 314 via a cable, and the control system 318 can communicate with the wireless communication circuit 390 via the cable. Alternatively, the wireless communication circuit 390 can be directly coupled to the control board 415 of the control system 318. The control system 318 can receive user commands from the display unit 314 via the detachable tether 317 (e.g., cable), and can direct the operation of the display unit 314 according to the status of the water treatment system 100. For example, the control system 318 can command the display unit to indicate information related to when to replace the filter assembly 170 and / or the filter group 156 of the water treatment system 100.

[0284] The control system 318 in the illustrated embodiment is operable to obtain sensor output from the sensor unit 316. The control system 318 may change operation and / or display information via the display unit 314 based on the sensor output obtained from the sensor unit 316.

After the connection to the control system 318' has been established between the wireless communication circuit 390', the display unit 314', and any sensors (e.g., the sensor unit 316'), Fig.43The control system 318' in the illustrated embodiment can be directly plugged into or connected to the UV reactor 380'. The connection to the UV reactor 380' can be made via a connection panel on the underside of the control system 318'. The connection panel can also provide connectors for the wireless communication circuit 390', the display unit 314' and any sensors. The connection panel disposed on the underside of the control system 318' can facilitate hiding the connections from any angle, thereby improving the overall aesthetics of the assembly and substantially shielding the electronic connections from any accidental water splashes.

[0286] The control system 318, 318' may be configured to receive power from a separate power connection via a connection through the housing or cover 310, 310', which may also be configured to condition and distribute power to other systems of the water treatment system 100, 100' according to design constraints.

[0289] B. Display unit

[0290] The display unit 314 in the illustrated embodiment may include one or more presentation features and data interpretation systems for providing water treatment system information and receiving control instructions (e.g., from a user or another device). For example, in one embodiment, the display unit 314 is operable to receive control feedback from a user. Such feedback may be provided via a (mechanical and / or proximity-based) switch input, based on which the user may operate to control a function of the water treatment system 100. Although the display unit 314 and the control system 318 are described separately, it should be understood that these components may be provided by the same system or as a single entity.

[0291] In the illustrated embodiment, the display unit 314 is operable to interpret a subset of the data from the data stream provided by the control system 318 to support the intent of the system and the current display unit configuration. For example, the control system 318 is operable to transmit information according to a determined protocol, and the display unit 314 can be configured to convert the protocol into information according to the display configuration of the display unit 314.

[0292] exist Fig.44 In the illustrated embodiment, the display unit 314 may include an LED array 424 operable to direct light through a graphic mask 422 (e.g., a display mask), wherein the graphics are aligned with the light generated from the LED array 424.

[0293] Fig.41 The illustrated embodiment provides a display unit 314' for a base assembly 110' and includes an LED array 424 having parabolic elements and a graphic mask 422, wherein appropriate graphics are aligned with the parabolic elements. Similar to the display unit 314, the display graphics of the display unit 314' can be presented in a "dead-front" panel that, in one embodiment, presents only the currently associated touch points to the user. For example, unless the display unit 314' activates the LED associated with the graphic element, the graphic elements of the graphic mask 422' can remain substantially unmasked or hidden from view.

[0294] Portions of the graphic mask 422, 422' may be associated with user inputs (e.g., mechanical switches or proximity-based inputs, such as capacitive touch) to facilitate user control of the water treatment system 100, 100'. The display unit 314, 314' may also include a display unit body 423 or first housing member 423', and an optional second housing member 425', which may be used to support the LED array 424, 424' of the display unit 314, 314'. In one embodiment, the first housing member 423, 423' may substantially protect the circuitry or control board 415' of the display unit 314, 314' from water and modularize the display unit 314, 314' so that it may be replaced with another display unit 314, 314' having a similar or different configuration but having a consistent form factor.

The UV reactor 380 as discussed herein includes a UV reactor inlet 382 for receiving water and a UV reactor outlet 384 for discharging water that has been disinfected by UV energy. The UV reactor 380 can be configured to direct UV energy to the water received via the UV reactor inlet 382 to disinfect the water. An example of a UV reactor 380 is provided in U.S. Patent Application No. 62 / 880,688, filed on July 31, 2019 by Wu et al., entitled WATER TREATMENT SYSTEM - the disclosure of which is incorporated herein by reference in its entirety.

[0299] exist Fig.42 In the illustrated embodiment, a UV reactor 380' is provided that is similar in some respects to the UV reactor 380, and includes a UV reactor inlet 382' and a UV reactor outlet 384'. Water is directed from the UV reactor inlet 382' to a UV reaction chamber (not shown) inside the UV reactor 380' through a transfer fluid path 388', thereby sterilizing the water. The sterilized water can be discharged from the UV reactor 380' to the UV reactor outlet 384'.

The stages in the illustrated embodiment are indicated by letters AE, with different views of the same stage being shown in FIG. Figure 1A-1E and Figure 2A-2E share the same alphabetic representation. For example, Figure 1A The perspective view in the figure depicts the Figure 2A 1 and 2. The side view in FIG. 2 shows the processing assembly 130 and the base assembly 110 in the same position.

[0302] exist Figure 1Aand Figure 2A In the illustrated embodiment, the treatment assembly 130 is shown removed or separated from the base assembly 110. The treatment assembly 130 can be carried to another location (e.g., a sink) for maintenance via the handle assembly 136. As discussed herein, the closure assembly 132 can be removed from the treatment assembly 130 to expose the filter assembly 170 or filter bank 156 carried within the treatment assembly 130. For purposes of discussion, this method is combined with removing the filter assembly 170 from the base assembly 110. Figure 1A and Figure 2A The illustrated embodiment is described with the installation or engagement of the processing assembly 130 with the base assembly 110 beginning at the position or stage shown. In one embodiment, removal of the processing assembly 130 from the base assembly 110 may be accomplished by reversing the method steps used for installation.

[0303] Starting at the stage where the treatment assembly 130 is separated from the base assembly 110, a user who wishes to install the treatment assembly 130 into the base assembly 110 may lift the treatment assembly 130 with the handle assembly 136 and tilt the treatment assembly 130 relative to the base assembly 110 at an approximate angle Φ between the central axis 234 and the vertical or longitudinal axis 460 of the base assembly 110. The user may then connect the water inlet coupling 231 with the water supply coupling 332 to form a fluid connection between the base assembly 110 and the treatment assembly 130. This connection may be facilitated by applying an axial force along the central axis 234 of the treatment assembly 130. The water inlet coupling 231 may be connected to the water supply coupling 332 to form a fluid connection between the base assembly 110 and ... Figure 1B-Figure 1C and Figure 2B-2C This progression of tilting and insertion of the treatment assembly 130 is seen in the illustrated embodiment.

[0304] Angle Φ in one embodiment may be defined as a tilt angle that prevents further pivoting of treatment assembly 130. Connector support 330 may allow water supply coupling 332 to pivot to angle Φ but not further. The connection between water supply coupling 332 and treatment water inlet coupling 231 may be sufficient to prevent treatment assembly 130 from falling out of or loosely detaching from base assembly 110. Treatment assembly 130 may be configured so that its center of mass is not too far relative to base 105 (e.g., lower portion) of base assembly 110, where torque moments on the connection with water supply coupling 332 may cause it to malfunction or cause treatment assembly 130 to loosely detach or fall out of base assembly 110.

[0305] Removal of the processing assembly 130 may be associated with Fig.52C and Fig.53C The stages depicted in FIG. 1 are relatedly achieved by applying an axial force along the central axis 234 via the handle assembly 136 to pull the processing assembly 130 out of the base assembly 110 .

[0306] As described herein, the handle assembly 136 and the releasable coupling 263 of the closure assembly 132 can be aligned with the first and second base receiving portions 350, 352 via receiving the alignment member 137 within the base assembly receiving portion 342. If the alignment member 137 is not aligned with the base assembly receiving portion 342, then in one embodiment, the processing assembly inlet 131 and the releasable coupling 263 can be prevented from engaging with the base assembly 110.

[0307] To fully engage the processing assembly 130 with the base assembly 110, the user may rotate the handle assembly 136 to the engaged position 262, such as Figure 1E and Figure 2E The handle assembly 136 is directed from the operable position 261 to the Fig.53E The rotation of the angle θ depicted in the illustrated embodiment can cause the distal ends of the first and second engagement members 271 to engage the first and second catches 354, 356 of the first and second base receiving portions 350, 352, wherein the first and second catches 354, 356 are under tension. In this way, the first and second engagement members 271 can maintain their positions relative to the first and second catches 354, 356 of the first and second base receiving portions 350, 352 and generally maintain the position of the handle assembly 136 in the engaged position 262.

[0308] exist Figure 1A-1E , Figure 2A-2E , Fig.18 and Fig.21 In the illustrated embodiment, when the treatment assembly 130 is coupled to the base assembly 110 to treat water, it is noted that water can enter the water treatment system 100 through the inlet elbow 372, which can be rotated (e.g., approximately 180 degrees) to allow the attached water inlet pipe 112 to be routed to either side of the water treatment system 100. Water can exit the inlet elbow 372 and flow around the treatment assembly connector 374, which can be rotated (e.g., approximately 16 degrees, in Fig.21 150 and the like. The water may then flow through the primary filter 150 and the filter media 171 (e.g., a carbon block) of the filter assembly 170 and out of the opening or fluid path 275 of the upper end cap 175 (e.g., a top end cap weld assembly). The water then flows out of the treatment assembly outlet 133 of the container interface 240 and out of the filter assembly 170.

[0309] As discussed herein, the base member 391 of the base assembly 110 may include an RFID antenna 395 (e.g., a wireless communication antenna) that is positioned to communicate with the RFID component 272 (e.g., a wireless communication component) of the filter assembly 170. The installation method described herein may be performed regardless of the orientation of the filter assembly 170 because the location of the RFID antenna 395 and the RFID component 272, or wireless communication aspects thereof, are proximate to the longitudinal center axis of the filter assembly 170. Regardless of the rotational orientation of the filter assembly 170 about the center axis 234 of the treatment assembly 130, the RFID component 272, or wireless communication aspects thereof, may be positioned proximate to the RFID antenna 395 when the treatment assembly 130 according to one or more embodiments described herein, including the water treatment system 100 and the water treatment system 100', is installed or connected to the base assembly 110.

[0310] According to one embodiment, a water treatment system 100' including a treatment assembly 130' and a base assembly 110' is provided. Figure 52A-Figure 52E and Figure 53A-Figure 53E The water treatment system 100' is depicted in various stages associated with the installation and removal of the treatment assembly 130' to the base assembly 110'. The stages in the illustrated embodiment are indicated by letters AE, and different views of the same stage are shown in FIG. Figure 52A-Figure 52E and Figure 53A-Figure 53E The same letters are used in the Chinese language. For example, Fig.52A The perspective view in the figure depicts the Fig.53A The side view of FIG. 1 shows the processing assembly 130 ′ and the base assembly 110 ′ in the same position.

[0311] exist Fig.52A and Fig.53A In the illustrated embodiment, the treatment assembly 130' is shown removed or separated from the base assembly 110'. The treatment assembly 130' can be carried to another location (e.g., a sink) via the handle assembly 136' for maintenance. As discussed herein, the closure assembly 132' can be removed from the treatment assembly 130' to expose the filter assembly 170' or filter bank 156' carried within the treatment assembly 130'. For the purposes of discussion, this method is combined with the removal of the filter assembly 170' or filter bank 156' from the treatment assembly 130'. Fig.52A and Fig.53A The illustrated embodiment is described with the installation or engagement of the processing assembly 130' with the base assembly 110' beginning in the position or stage shown. In one embodiment, removal of the processing assembly 130' from the base assembly 110' may be accomplished by reversing the method steps used for installation.

[0312] Beginning at the stage where treatment assembly 130' is separated from base assembly 110', a user who wishes to install treatment assembly 130' into base assembly 110' may lift treatment assembly 130' with handle assembly 136' and tilt treatment assembly 130' relative to base assembly 110' at an approximate angle Φ relative to a vertical or longitudinal axis 460' of base assembly 110'. The user may then connect water inlet coupling 231' with water supply coupling 332' to form a fluid connection between base assembly 110' and treatment assembly 130'. This connection may be facilitated by applying an axial force along central axis 234' of treatment assembly 130'. The user may then connect water inlet coupling 231' with water supply coupling 332' to form a fluid connection between base assembly 110' and treatment assembly 130'. The connection may be facilitated by applying an axial force along central axis 234' of treatment assembly 130'. Figure 52B-Figure 52C and Figure 53B-Figure 53C The illustrated embodiment shows the progression of tilting and insertion of the treatment assembly 130'.

[0313] Angle Φ in one embodiment can be defined as a tilt angle that prevents further pivoting of treatment assembly 130'. Connector support 330' can allow water supply coupling 332' to pivot to angle Φ but not further. The connection between water supply coupling 332' and treatment water inlet coupling 231' can be sufficient to prevent treatment assembly 130' from falling out of or loosely detaching from base assembly 110'. Treatment assembly 130' can be configured so that its center of mass is not too far relative to lower portion 105' of base assembly 110', where the torque moment on the connection with water supply coupling 332' can cause failure or treatment assembly 130' to loosely detach or fall out of base assembly 110'.

[0314] The removal of the processing assembly 130' can be done with Fig.52C and Fig.53C The stages depicted in FIG. 1 are relatedly achieved by applying an axial force along the central axis 234 ′ via the handle assembly 136 ′ to pull the processing assembly 130 ′ out of the base assembly 110 ′.

[0315] As described herein, the handle assembly 136' and the releasable coupling 263' of the closure assembly 132' can be aligned with the first and second base receiving portions 250', 251' via receiving the alignment member 137' within the base assembly receiving portion 342'. If the alignment member 137' is not aligned with the base assembly receiving portion 342', then in one embodiment, the processing assembly inlet 131' and the releasable coupling 263' can be prevented from engaging with the base assembly 110'.

[0316] exist Figure 52B-Figure 52D and Figure 53B-Figure 53DIn the illustrated embodiment, the handle assembly 136' is depicted in a position between the operable position 261' and the engaged position 262', approximately at an angle θ relative to the central axis 234' of the treatment assembly 130'. In the illustrated embodiment, if the handle assembly 136' is in the operable position 261', the distal ends of the first and second tightening clips 251' are positioned to engage with the first and second base pins 351', 353', thereby substantially preventing further reduction of the angle φ between the treatment assembly 130' and the longitudinal axis 460' and preventing the first and second tightening clips 251' from engaging with the first and second base pins 351', 353'.

[0317] In the illustrated embodiment, when the handle assembly 136' is positioned approximately at the angle θ, the distal ends of the first and second tightening clamps 251' can move away from or pass over the first and second base pins 351', 353' so that a) the angle φ can be reduced, and b) the central axis 234' and the longitudinal axis 460' can be aligned. As described herein, the alignment of the central axis 234' and the longitudinal axis 460' can achieve a connection between the treatment assembly outlet 133' and the treated water inlet 362' of the base assembly 110'.

[0318] To fully engage the processing assembly 130' with the base assembly 110', the user may rotate the handle assembly 136' to the engaged position 262', such as Fig.52E and Fig.53E The handle assembly 136' is for Fig.53D Further rotation of the angle θ depicted in the illustrated embodiment can cause the distal ends of the first and second tightening clips 251' to capture the first and second base pins 351', 353' and, in conjunction with the over-center arrangement of the first and second tightening pins 252' relative to the first and second handle pins 248', hold the first and second base pins 351', 353' under tension. In this way, the first and second tightening clips 251' and the first and second base pins 351', 353' can remain engaged and generally maintain the position of the handle assembly 136' in the engaged position 262'.

[0319] It should be noted that Figure 52A-Figure 52E and Figure 53A-Figure 53EIn the illustrated embodiment, the first and second base pins 351', 353' are shown separated from the base assembly 110' and the first and second base receiving portions 350', 352' for purposes of disclosure. Instead, the positions of the first and second base pins 351', 353' are shown relative to the distal ends of the first and second tightening clamps 251' to indicate the positions of these components for various angles θ and Φ, including positions between the operable position 261' and the engaged position 262'. In practice, the first and second base pins 351', 353' are arranged within the first and second base receiving portions 350', 352' so that tension on the first and second tightening clamps 251' substantially maintains the treatment assembly 130' in engagement with the base assembly 110' relative to the tightening pins 252', the handle pin 248', and the first and second base pins 351', 353' and facilitates providing a watertight connection between the inlet and outlet between the treatment assembly and the base assembly 110'.

[0320] V. First Alternative Engagement Configuration

[0321] A water treatment system according to one embodiment of the present invention is Figure 53A-Figure 53D and Figure 54A-Figure 54D 5 and generally designated 500. The water treatment system 500 in the illustrated embodiment includes a treatment assembly 530 and a base assembly 510, similar to the water treatment system 100 including the treatment assembly 130 and the base assembly 110, with several exceptions. For example, the base assembly 510 in the illustrated embodiment is operable to be removably coupled to the treatment assembly 530 such that a water treatment assembly outlet 533 of the treatment assembly 530 can be a) connected to the base assembly 510 to form a watertight connection, and b) disconnected from the base assembly 510. The treatment assembly 530 can include a treatment assembly inlet (not shown) similar to the treatment assembly inlet 131, which is operable to be connected to a water supply connection 580 of the base assembly 510. Likewise, the base assembly 510 includes a filter assembly similar to the filter assembly 170 of the water treatment system 100.

[0322] The base assembly 510 of the water treatment system 500, similar to the base assembly 110, includes a plurality of base assembly receivers 581 that are incorporated into the treatment assembly receiver 582 of the base assembly 510. The treatment assembly receiver 582 can be configured to receive a lower portion of the treatment assembly 530 and facilitate pivoting of the treatment assembly 530 relative to the base assembly 510. The plurality of base assembly receivers 581 in the illustrated embodiment can be aligned with at least one position of the treatment assembly 530, in which position, the treatment assembly 530 is facilitated to couple with the base assembly 510, thereby forming a watertight connection therebetween.

[0323] Similar to base assembly 110, base assembly 510 in the illustrated embodiment includes UV reactor 590 and display unit 515; however, as in Fig.54A As can be seen in the illustrated embodiment, the placement and housing configuration of base assembly 510 differs from base assembly 110, with base assembly 510 having UV reactor 590 and display unit 515 provided in a generally side-by-side configuration.

[0324] The base assembly 510 can include first and second base receiving portions 550, 551, similar to the first and second base receiving portions 350, 352, which are configured to facilitate connecting the processing assembly 530 to the base assembly 510. However, the configuration of the first and second base receiving portions 550, 551 is different. The first and second base receiving portions 550, 551 include first and second snaps 552, 553 that retain the corresponding first and second engagement members 570, 571 of the closure assembly 532. The first and second snaps 552, 553 can provide a) an opening that can receive the engagement members 570, 571 and b) a retaining member that engages with the engagement members 570, 571 to facilitate the connection of the base assembly 510 and the processing assembly 530.

[0325] Fig.55 The closure assembly 532 in the illustrated embodiment shows the engagement members 570, 571 in greater detail. The closure assembly 532 is similar to the closure assembly 132 with a few exceptions, such as the handle 560 including the first and second engagement members 570, 571 being configured differently than the cinch clip 251 of the closure assembly 132.

[0326] The closure assembly 532 includes projections 546, 547 that incorporate a handle pin 548 that fits through a hole 549 in the handle 560, allowing the handle 560 to be pivotally coupled to the closure assembly 532. The first and second engagement members 570, 571 can rotate with the handle 560, such that in the engagement position 562, the first and second engagement members 570, 571 engage with and are retained by the first and second catches 552, 553. Rotating the handle 560 from the engagement position 562, as shown in FIG. Figure 54A-Figure 54B As shown in the progress of , the first and second engagement members 570 , 571 can be disengaged from the first and second buckles 552 , 553 to facilitate removal of the processing assembly 530 from the base assembly 510 .

[0327] VI. Second Alternative Engagement Configuration

[0328] A water treatment system according to one embodiment of the present invention is Figure 56A-Figure 56E , Fig.57 and Fig.58600. The water treatment system 600 in the illustrated embodiment includes a treatment assembly 630 and a base assembly 610, similar to the water treatment system 100 including the treatment assembly 130 and the base assembly 110, with several exceptions. For example, the base assembly 610 in the illustrated embodiment is operable to be removably coupled to the treatment assembly 630 such that a water treatment assembly outlet 633 of the treatment assembly 630 can be a) connected to the base assembly 610 to form a watertight connection, and b) disconnected from the base assembly 610. The treatment assembly 630 can include a treatment assembly inlet (not shown) similar to the treatment assembly inlet 131, which is operable to be connected to a water supply connection 680 of the base assembly 610. Likewise, the base assembly 610 includes a filter assembly similar to the filter assembly 170 of the water treatment system 100.

[0329] The base assembly 610 of the water treatment system 600, similar to the base assembly 110, includes a plurality of base assembly receivers 681 that are incorporated into a treatment assembly receiver 682 of the base assembly 610. The treatment assembly receiver 682 can be configured to receive a lower portion of the treatment assembly 630 and facilitate pivoting of the treatment assembly 630 relative to the base assembly 610. The plurality of base assembly receivers 681 in the illustrated embodiment can be aligned with at least one position of the treatment assembly 630, in which position, to facilitate coupling of the treatment assembly 630 with the base assembly 610, thereby forming a watertight connection therebetween.

[0330] Similar to the base assembly 110 , the base assembly 610 in the illustrated embodiment includes a UV reactor 690 and a display unit 615 .

[0331] The base assembly 610 may include a pivotable engagement structure 650 that is rotatably coupled to the cover assembly 611 via a coupling between a pin 651 and a receptacle 652. The pivotable engagement structure 650 may take the form of a partial ring or band that pivots to engage the treatment assembly engagement surface 670 and hold the treatment assembly 630 in position relative to the base assembly 610 and maintain a watertight connection between the treatment assembly 630 and the respective inlets and outlets of the base assembly 610. The pivotable engagement structure 650 may be rotated away from the treatment assembly engagement surface 670 to facilitate removal of the treatment assembly 630 from the base assembly 610.

[0332] In one embodiment, if Fig.57As further described in detail in , the pivotable engagement structure 650 or the treatment assembly engagement surface 670 or both may include a ramp or curved portion 672 that facilitates initial engagement of the two components and results in a friction fit portion 671 when the pivotable engagement structure 650 is rotated into engagement. This configuration can help an end user reengage the pivotable engagement structure 650 without requiring significant effort to push or hold the treatment assembly 630 in place. In addition, the friction fit portion 671 can facilitate maintaining engagement between the treatment assembly engagement surface 670 and the pivotable engagement structure 650. Figure 56A-Figure 56E The illustrated embodiment shows this progression between rotating the pivotable engagement structure 650 to engage the treatment assembly engagement surface 670 and mounting the treatment assembly 630 to the base assembly 610 .

[0333] VII. Display unit and user interface components

[0334] According to one embodiment of the present invention, a display unit is Fig.44 and Figure 45A-Figure 45D 960 and generally designated 314. As discussed herein, the display unit 314 can include an LED array 424 that includes a support substrate 426 for a first plurality of LEDs 960 and a second plurality of LEDs 962A-962C. The display unit 314 can include a display unit body 423 that can be operable to support the LED array 424 and direct light according to one or more embodiments described herein. For example, the display unit body 423 can include one or more apertures 954A-954C, 965 that can be operable to receive optical elements 950, 952A-952C to facilitate directing light from the LEDs 960, 962A-962C through the pattern mask 422 and through the display panel 970. In one embodiment, the display panel 970 can facilitate providing the display 315, which can be a front-side wireless display in conjunction with the pattern mask 422, the optical elements 950, 952A-952C, and the LEDs 960, 962A-962C.

[0335] In one embodiment, the graphic mask 422 may include graphic elements 956A-956C, 966 that allow light to pass through the graphic mask 422. The graphic elements 956A-956C, 966 may correspond to icons that are associated with information that can be recognized by a user. The icon may take the form of a graphic symbol that is a pictorial representation of information, such as a Wi-Fi symbol or a power on / off symbol. However, the icon is not limited to this form. The graphic elements 956A-956C, 966 may correspond to shapes or features that facilitate conveying information (e.g., status) to the user. For example, the graphic element 966 is in the form of a vertical bar that extends approximately from the upper portion of the display panel 970 to the lower portion. The vertical bar may emit light along the length of the vertical bar in a substantially uniform, consistent manner as discussed herein, even if the light is generated from a plurality of point light sources in the form of a first plurality of LEDs 960. The first plurality of LEDs 960 can be selectively controlled to produce a variable light output via a graphical element 966, such as a waterfall feature, a rolling pulse, a flashing, or any activation pattern or activation sequence of the LEDs 960, or a combination thereof. It should be noted that the LEDs 960, 962 can be controlled together or individually to produce light of varying intensities. The LEDs 960, 962 are shown and described as light emitting diodes, but the invention is not limited thereto. The LEDs 960, 962 can be any type of light source.

[0336] The display unit may include a connector 990 that can be connected to the detachable tether 317 .

[0337] according to Fig.46 , Fig.47 and Figure 48A-48C An embodiment of FIG. 3 shows display unit 314 in more detail. Fig.46 The display unit 314 in the illustrated embodiment is Fig.45B , a magnified view of a plurality of LEDs 960, labeled 960A, 960B, 960C, is shown for discussion purposes. Fig.47 Shows Fig.46 960A-960C. The display unit body 423 in the illustrated embodiment at least partially defines a light source generating region 967 having a body surface 964 that is substantially opaque to light generated from the LEDs 960A-960C.

[0338] The optical element 950 may include light receiving surfaces 968A-968C that at least partially define a light source generating area 967 and are curved or shaped relative to the light output from the LED 960 to provide a surface that is substantially perpendicular to the light output from the LED 960. The LED 960 may generate light having an output angle, such as 60°. The angle between each light beam output from the LED 960 and the light receiving surfaces 968A-968C may be substantially 90° or perpendicular, such that the boundary formed by the light receiving surfaces 968A-968C does not significantly affect the angle of each light beam. In the illustrated embodiment, the light receiving surfaces 968A-968B are concave relative to the LEDs 960A-960C and have a curvature with a focal point substantially aligned with the position of the LED 960. Avoiding redirecting light at the light receiving surfaces 968A-968B may substantially avoid the efficiency loss associated with such redirection.

[0339] In one embodiment, the LEDs 960 and light receiving surfaces 968A- 968C are operable to direct light output from an LED 960 to overlap light output from an adjacent LED 960 .

[0340] In the illustrated embodiment, the main body surface 964 and the optical boundary surface 965 of the optical element 950 can be separated from each other by a gap 961. The size of the gap 961 can be selected to form a boundary at the optical boundary surface 965 that provides internal reflection of light encountering the optical boundary surface 965 after the light enters the optical element 950. In one embodiment, the optical boundary surface 965 can be a polished surface to provide internal reflection of light. The gap 961 and internal reflection at or near the optical boundary surface 965 can facilitate providing a more uniform light distribution within the optical element 50, even if the light is generated from a point light source in the form of multiple LEDs 960. For example, from the user's perspective, the light output can be uniform so that there are no hot spots or areas of significantly higher light intensity. In one embodiment, the gap 961 can provide a more efficient light distribution within the optical element 950.

[0341] In the illustrated embodiment, it should be noted that in the region 969 between adjacent gaps 961 defined by the optical boundary surface 965 and the body surface 964, the optical element 950 and the body surface 964 are closely positioned, potentially in contact with each other. The angle of the gap 961 relative to the output angle of the LED 960 can be configured so that light output from the LED 960 is not provided directly within or toward the gap 961, yet the optical boundary surface 965 is close to the limit of the output beam generated by the LED 960, as shown. In this way, light from the LED 960 can enter the optical element 950 and be retained within the optical element 50 in an efficient manner.

[0342] The arrangement and configuration of the LEDs 960, the display unit body 423, and the graphical element 966 can provide a substantially uniform light output via the graphical element 966, even if the light is generated from multiple point light sources. The light visible to the user via the graphical element 966 can be considered to be substantially uniform as perceived by the user, so that significant variations in intensity relative to the graphical element 966 are not presented to the user. Fig.47 The light density shown in the illustrated embodiment is not substantially uniform relative to the graphical elements 966; however, it should be noted that the light beam shown in the illustrated embodiment corresponds to a first pass of light through the optical element 950. As discussed herein, the optical element 950 can be configured and positioned so that light reflects within and exits the optical element 950 in a substantially uniform manner in the area corresponding to the graphical elements 966.

[0343] Steering Figure 48A-48C The embodiment shown shows the light path within the optical element 950 in more detail. The optical element 950 can be a transparent optical device or transparent material that can be operated to allow light transmission without significant power loss. The optical element 950 can include a mask-facing surface 971 and a light scattering surface 972, as well as a light receiving surface 968 described herein.

[0344] exist Fig.48A 960B and enter the optical element 950 via a light receiving surface 968, which can be polished and constructed relative to the position of the LED 960B to provide low or minimal light redirection. The light can be reflected within the optical element 950 via a light scattering surface 972, which can be incorporated into the display unit body 423 to promote light scattering. Light scattering according to one embodiment can involve diffuse reflection or reflection of light from a surface, so that the light incident on the surface is scattered at more than one angle. The light scattering surface 972 in the illustrated embodiment can promote internal reflection of light in a scattered manner.

[0345] exist Fig.48B In the illustrated embodiment, light scattering within the optical element 950 is shown in a representative manner. The mask-facing surface 971 and the rear-facing surface 973, as well as the light-receiving surface 968 and the optical boundary surface 965 can be configured to provide internal reflection of light (for example, these surfaces can be polished). The internal reflection combined with the light scattering surface 972 can facilitate filling the optical element 950 with light in a substantially uniform manner.

[0346] Fig.48CThe illustrated embodiment depicts a representative view of the concentrated scattering and reflection of light within the optical element 950. In the illustrated embodiment, when the incident angle of the light relative to the mask-facing surface 971 is greater than the escape angle (e.g., greater than about 45°) and the light corresponds to the location of the graphical element 966, the light can escape from the optical element 950 and be externally visible to a user of the water treatment system 100.

[0347] The configuration of the light receiving surface 968, the gap 961, and the positioning of the LED 960 can achieve relative Fig.47 960, 975, a more compact configuration. It should be noted that by increasing the distances PB and FC, for a given spacing LS between LEDs 960, 975, a more uniform light distribution about the graphic element 966 can be achieved without including the gap 961 and the associated configuration. However, the light receiving surface 968 and the gap 961, as well as the surface configuration of the optical element 950, can enable the distances PB and FC to be reduced to provide a more compact configuration. In the illustrated embodiment, the distances PB, FC, and LS for LED 960 are approximately 0.46", 0.36", and 1.0", respectively. The distances PB, FC, and LS for LED 975 are approximately 1.0", 0.89", and 1.0", respectively.

[0348] In the illustrated embodiment, a substantially uniform distribution of light within the optical element 950 can be provided: the ratio of the distance between the LED 960 and the body boundary 976 (e.g., the distance PB) to the spacing between adjacent LEDs 960 (e.g., the distance LS) can be approximately 0.48:1 (e.g., the distance LS is approximately twice the distance PB). The ratio of the distance between the LED 960 and the center of the graphical element 966 (e.g., the distance FC) to the distance LS can be approximately 0.35:1 (e.g., the distance LS is approximately 2.8 times the distance FC). In contrast, for the LED 975, the ratio of the distance PB to the distance LS can be 1:1, while the ratio of the distance FC to the distance LS can be 0.88:1. The ratio of distance PB to distance LS can be 0.75:1 or less (e.g., distance LS is 1.3 times or greater than distance PB), optionally 0.50 or less (e.g., distance LS is 2 times or greater than distance PB), wherein the position of LEDs 960 and the configuration of optical element 950 provide a substantially uniform light distribution within the optical element, even if the light is generated from point light sources in the form of multiple LEDs 960.

[0349] As described herein, various portions of display unit 314 may accept user feedback. These portions may include a capacitive touch sensor operable to detect the presence of a user's finger and provide information indicating the detected presence to control system 318. Control system 318 may use this information to change the state of water treatment system 100 or provide information to the user via display 315, such as by instructing display unit 314 to change display characteristics.

[0350] exist Fig.49 , Figure 50A-Figure 50B and Figure 51A-Figure 51C In the illustrated embodiment, various aspects of the display unit 314 are shown in greater detail. Fig.49 Depicted Fig.45B is an enlarged view of the display unit 314, and Figure 50A-Figure 50B Shows Fig.49 962A. The display unit 314 may include an optical element 952A and an LED 962A disposed within a hole 954 of a display unit body 423, which may be opaque. The optical element 952 may be configured to receive light from the LED 962A via a light receiving surface 978A. The light receiving surface 978A may be similar to the light receiving surface 968A, such that the light receiving surface 978A may have a curvature and position relative to the LED 962A, so that the direction of the light of the LED 962A received by the optical element 952A is substantially the same before and after passing through the light receiving surface 978A. For example, the light receiving surface 978A may be a convex surface having a curvature, the focus of which is substantially aligned with the position of the LED 962A, so that the light generated from the LED 962A passes through the light receiving surface 978 at an angle of approximately 90° or perpendicular to the light receiving surface 978 to substantially avoid redirection of the light entering the optical element 952A.

[0351] exist Figure 51A-Figure 51C In the illustrated embodiment, the optical path within the optical element 952A is shown in more detail. The optical element 952A can be a transparent optical device or a transparent material that can be operated to allow light transmission without substantially low power. The optical element 952A can include a surface 981 facing the mask, a light scattering surface 982, and a surface 983 facing the rear.

[0352] The first pass of light within the display unit 314 is typically performed at Fig.50A and Fig.51A962A and enter the optical element 952A via a light receiving surface 978A, which can be polished and constructed relative to the position of the LED 962A to provide low or minimal light redirection. The light can be reflected within the optical element 952A via a light scattering surface 982, which can be incorporated into the display unit body 423 to promote light scattering. Light scattering according to one embodiment can involve diffuse reflection or reflection of light from a surface, so that light incident on the surface is scattered at more than one angle. The light scattering surface 982 in the illustrated embodiment can promote internal reflection of light in a scattered manner.

[0353] exist Fig.50B and Fig.51B In the illustrated embodiment, light scattering within optical element 952A is shown in a representative manner. Mask-facing surface 981 and light receiving surface 978A can be configured to provide internal reflection of light (e.g., these surfaces can be polished). Similar to light scattering surface 982, rear-facing surface 983 can be configured for light scattering (e.g., having a diffuse reflective finish). Internal reflection combined with light scattering can facilitate filling optical element 952A with light in a substantially uniform manner.

[0354] Fig.48C The illustrated embodiment depicts a representative view of the concentrated scattering and reflection of light within the optical element 952A. In the illustrated embodiment, when the incident angle of the light relative to the mask-facing surface 981 is greater than the escape angle (e.g., greater than about 45°) and the light corresponds to the location of the graphical element 956A, the light may escape the optical element 952A and be externally visible to a user of the water treatment system 100.

[0355] VIII. Alternative User Interface Components

[0356] According to one embodiment of the present invention, a display unit is Fig.60 7 and generally designated 715. Display unit 715 is similar to display unit 314 described in connection with water treatment system 100, with several exceptions. Display unit 715 in the illustrated embodiment, along with cover 700 and water treatment system 100, may provide a user interface component for operating water treatment system 100.

[0357] The display unit 715 in the illustrated embodiment can be a modular unit that can be engaged with the cover 700, in a manner similar to the display unit 715, and the cover 700 can be similar to the cover 310 described in conjunction with the water treatment system 100, but with several exceptions. For example, in the illustrated embodiment, the cover 700 can include a plurality of ribs 701 disposed on an outer surface of the cover 700. In addition, the cover 700 can include a display unit receiving portion 716 configured to engage with the display unit 715 and hold the display unit 715 in place for operation. The display unit receiving portion 716 can include a space to accommodate the display unit 715 and one or more recesses or holes 724, which can be operated to accommodate one or more corresponding protrusions 725 disposed on the display unit 715. In the illustrated embodiment, the display unit 715 can engage the display unit receiving portion 716 by "snapping" or "clicking" the display unit 715 into the display unit receiving portion 716, via the engagement of one or more protrusions 725 with one or more holes 724. The display unit receiving portion 716 can be configured such that, after the display unit 715 is engaged with the display unit receiving portion 716, removal of the display unit 715 can be substantially impeded without removing the cover 700 and accessing the one or more apertures 724 from within the interior space of the cover 700. Although not shown, the display unit receiving portion 716 can include an electrical connector that is operable to mate and form an electrical connection with a corresponding electrical connector disposed on the display unit 715. In this way, the display unit 715 can receive power from the water treatment system 100 and communicate with the control system 318 of the water treatment system 100 (e.g., via one or more serial communication links, or one or more separate inputs and outputs, or any combination thereof).

[0358] exist Fig.60 In the illustrated embodiment, the cover 700 may include a reflector 720 operable to reflect light received from the display unit 715, as well as light reflected toward the display unit 715 and / or light reflected within a channel 722 disposed between the reflector 720 and a cover surface 721 that functions as a reflector like the reflector 720. However, in the illustrated embodiment, the cover surface 721, instead of receiving light directly from the display unit 715, may receive such light indirectly via reflection from the reflector 720.

[0359] The display unit 715, the reflector 720, and the cover surface 721 can operate in conjunction with each other to provide light within the channel 722. Such light within the channel 722 can include one or more lighting effects, such as a gradient effect provided by successive reflections of light between the reflector 720 and the cover surface 721. Fig.59The gradient effect is seen in one embodiment of the invention, where a light intensity graph 717 is depicted next to a channel 722 of the cover 700. The light intensity graph 717 shows that the light intensity in the channel 722 near the central portion of the light source or display unit 715 is greater than the light intensity in the portion of the channel away from the central portion of the light source or display unit 715.

[0360] The light in the channel 722 can be controlled via the light output from the display unit 715 to provide end-user status information about the operation of the water treatment system 100. In one embodiment, the light in the channel 722 can provide such status information that can be seen at a glance from a distance (e.g., greater than an arm's length away). For example, the display unit 715 can illuminate the channel 722 with a light whose color changes according to the state of the water treatment system 100. For example, when the system is active and the operation meets one or more operating condition parameters, a blue light can be displayed. When the system is active but operates in a manner that does not meet one or more operating condition parameters, a red light can be displayed. In one embodiment, the display unit 715 can also flash the light to convey information to the end user, such as by flashing blue to indicate that the water treatment system 100 is operating to treat water. The display unit 715 can gradually change between the two states when turning the light on or off, so that the change of state is not sudden. It should be understood that the light output from the display unit 715 can be controlled in a variety of ways and is not limited to those described herein.

[0361] The display unit 715 may also include one or more feedback indicators 718A-718E. The feedback indicators 718A-718E may convey status information to an end user that may be understood at a closer distance than the distance of the light provided by the display unit 715 to the channel 722. For example, in the illustrated embodiment, the feedback indicator 718A provides a maintenance indicator that indicates to the end user that the water treatment system 100 may require maintenance, the feedback indicator 718B may be a level indicator that displays the remaining useful life of the carbon block filter, and the feedback indicator 718C may identify whether the UV reactor is operating and, if so, whether the UV reactor is operating in accordance with one or more operating parameters (e.g., blue for compliance and red for noncompliance). The feedback indicator 718D may indicate whether the water treatment system 100 is operably connected to a first type of wireless network, such as a Wi-Fi network. The feedback indicator 718E may indicate whether the water treatment system 100 is operably connected to a second type of wireless network, such as a Bluetooth network. The one or more feedback indicators 718 may be configured to provide a variety of lighting effects as described herein, but it should be understood that the present invention is not limited thereto. Feedback indicator 718 may provide any type of lighting effect.

[0362] In the illustrated embodiment, the feedback indicator 718 may be additionally or alternatively associated with a user input. The user input may take the form of a capacitive input or other type of touch-based input. Circuitry for such touch-based input may be provided near or on the surface of a display unit accessible to an end user.

[0363] Steering Figure 61-Figure 63 In the illustrated embodiment, the display unit 715 is shown in more detail in an exploded view and two cross-sectional views. The display unit 715 may include one or more of the following components: a back cover 750, a display unit circuit 752, a housing 754, a guide assembly 756, an optical cover 758, and a decorative assembly 760. The guide assembly 756 may include one or more light guides 786 configured to engage with one or more light sources provided by the display unit circuit 752 and direct light therefrom to the optical cover 758. In the illustrated embodiment, the optical cover 758 may include an optical mask 759 that enables light to pass from the light guide 786 to an area outside the water treatment system 100 according to a mask area associated with the light guide 786. For example, the optical mask 759 may define one or more symbols associated with one or more feedback indicators 718A-718E, respectively, to allow light from the light guide 786 to illuminate an area not obscured by the optical mask 759.

[0364] The housing 754 in the illustrated embodiment includes an interior space 772 defined by a sidewall 771, the interior space 772 being configured to receive the guide assembly 756 and the display unit circuit 752. The housing 754 includes an output opening 776 through which light can pass from the guide assembly 756. The housing 754 may include a rear opening 774, which may be covered by the rear cover 750 in an assembled state. In the illustrated embodiment, the housing 754 may include a recess 753 disposed around the inner perimeter of the housing 754 proximate to the rear opening 774. The rear cover 750 may be configured to fit at least partially within the recess 753, thereby maintaining the mounted position of the rear cover 750 and facilitating retention of components within the housing 754 or protection of these components, or a combination thereof.

[0365] The display unit 715 of the illustrated embodiment includes a display unit circuit 752 configured to provide a power supply circuit for supplying energy to a primary light source 762 and a secondary light source 764, which are alternatively described herein as a first light source and a second light source, respectively. The primary light source 762 can be arranged near the central longitudinal axis of the display unit circuit 752, and the secondary light source 764 can be arranged near the perimeter of the display unit circuit 752. In the illustrated embodiment, the display unit circuit 752 includes a plurality of primary light sources 762A-762E and a plurality of secondary light sources 764A-764D. The secondary light source 764 can be arranged near the side wall portion 770, optionally on one side of the display unit circuit 752.

[0366] In the illustrated embodiment, the housing 754 includes a sidewall portion 770 which, for purposes of this disclosure, is Figure 61-Figure 63 780 is shown in dashed lines in the illustrated embodiment. It should be understood that the sidewall portion 770 may include any portion of the housing 754, including the entire housing 754. The sidewall portion 770 in the illustrated embodiment is at least translucent, and optionally transparent, to the light generated from the secondary light source 764 of the display unit 715. The sidewall portion 770 in the illustrated embodiment is a lens through which the light from the secondary light source 764 of the display unit 715 can be directed. In the illustrated embodiment, the lens includes a first lens surface 781 and a second lens surface 782.

[0367] Figure 62-Figure 63 The housing 754 in the illustrated embodiment is configured to house the display unit circuit 752 such that the positions of the printed circuit board of the display unit circuit 752 and the primary and secondary light sources 762, 764 align the primary light source 762 with the light guide 786 and align the secondary light source 764 with the lens defined by the side wall portion 770. The light guide 786 and the printed circuit board of the display unit circuit 752 may be connected to each other to provide a light-tight construction or to provide an interface that spatially prevents light generated from the primary light source 762 from leaking into the space defined between the side wall portion 770 and the light guide 786. Likewise, the interface between the light guide 786 in the printed circuit board of the display unit circuit 752 may prevent light generated from the secondary light source 764 from leaking into the inner cavity of the light guide 786.

[0368] The guide assembly 756 in the illustrated embodiment may be received by the housing 754 in its interior space 772. A lip 791 of the guide assembly 756 may engage the sidewall 771 of the housing 754 near the optical output opening 776. An optical cover 758 including an optical mask 759 may be positioned to contact the lip 791 of the guide assembly 756. A trim assembly 760 may be fitted around the perimeter of the optical cover 758 and configured to engage a recess defined by the sidewall 771 of the housing 754 to hold both the optical cover 758 and the guide assembly 756 in place.

[0369] In one embodiment, the back cover 750 can be configured to be connected to the printed circuit board of the display unit circuit 752 so as to position and hold the printed circuit board of the display unit circuit 752. For example, the back cover 750 can be connected to the printed circuit board to sandwich the printed circuit board between a) at least one of the housing 754 and the guide assembly 756 and b) the back cover 750.

[0370] The light guide 786 in the illustrated embodiment includes a reflector surface 784 configured to define an interior cavity of the light guide 786 in which light from the primary light source 762 is guided. In one embodiment, the reflector surface 784 can define an expanded shape or an intentional shape.

[0371] The reflector surface 784 can be shaped in a variety of ways depending on the application in order to direct light from the primary light source 762 toward the optical cover 758. In one embodiment, the reflector surface 784 can be configured to provide a substantially uniform light distribution across the optical mask 759 of the optical cover 758, thereby promoting a substantially uniform distribution of light transmitted outwardly from the optical cover 758. In the illustrated embodiment, the reflector surface 784 is substantially defined by a parabolic surface (e.g., a circular parabola) that is configured to direct light from the first or primary light source 762 toward the optical cover 758. Such a configuration can produce a light distribution across the inner surface of the optical cover 758 in a substantially uniform manner.

[0372] Fig.63The first lens surface 781 shown in the illustrated embodiment is provided at an acute angle 780 relative to a plane defined by a printed circuit board of the display unit circuit 752. The plane may be perpendicular to an axis defining the primary light emission direction of the secondary light source 764. It should be understood that the angle 780 may vary depending on the design parameters for different applications. According to one embodiment described herein, the angle 780 may be determined to facilitate directing light from the secondary light source 764 to the sidewall portion 770, and potentially toward the reflector 720. The first lens surface 781 may be configured to receive light directly from the secondary light source 764. The primary light path 790 illustrates this direct path from the secondary light source 764 through the first lens surface 781 and to the outside of the sidewall portion 770.

[0373] like Figure 62-Figure 63 In the illustrated embodiment, a portion of the interior space 772 (e.g., air) may exist between the secondary light source 764 and the first lens surface 781. It should be understood that this space between the secondary light source 764 and the first lens surface 781 may be filled with a substance other than air, such as a solid optical waveguide.

[0374] The second lens surface 782 of the sidewall portion 770 in the illustrated embodiment can be configured to receive light indirectly from the secondary light source 764 via reflection from another surface. For example, in the illustrated embodiment, the guide assembly 756 can include a reflector surface 783 that is integral with the guide assembly 756 and external to the inner cavity defined by the reflector surface 784. The secondary light path 792 illustrates this indirect path provided from the secondary light source 764, reflected from the reflector surface 783, through the second lens surface 782, and external to the sidewall portion 770.

[0375] Primary optical path 790 may provide a primary illumination beam for light generated from display unit 715 and external to sidewall portion 770. Secondary optical path 792 may provide a secondary illumination beam for light generated from display unit 715 and external to sidewall portion 770, potentially a smooth fill beam.

[0376] The secondary lens surface 782 can provide an angle (relative to the plane of the printed circuit board) to facilitate the generation of the secondary illumination beam. Additionally or alternatively, the angle of the secondary lens surface 782 can be determined to facilitate providing space within the interior space 772 to accommodate the guide assembly 756 and enable light to be reflected from the reflector surface 783 of the guide assembly 756.

[0377] The positioning of the primary and secondary light sources 762, 764 on the printed circuit board of the display unit circuit 752 can vary from application to application. In the illustrated embodiment, the primary light source 764 is arranged on the printed circuit board to align with each of the light guides 786 of the guide assembly 756, respectively. The secondary light sources 764 are disposed on the printed circuit board in staggered positions relative to the primary light sources 762 along the longitudinal axis of the printed circuit board. This staggered positioning can facilitate the packaging of the primary and secondary light sources 762, 764 and the construction of the guide assembly 756 so that light from the secondary light sources 764 can be directed through the side wall portion 770.

[0378] An alternative implementation of a user interface component according to one embodiment of the present invention is Figure 65-Figure 67 . The water treatment system 100 according to one embodiment may include a cover 800, which is similar to the cover 700, but with several exceptions, and includes a differently shaped display unit 815. The cover 800 in the illustrated embodiment may include a display unit receiver 816, which is configured to engage with and retain the display unit 815. Similar to the cover 700 and the display unit 715, the display unit receiver 816 may include one or more recesses or apertures 824, which are operable to receive one or more corresponding protrusions 825 through the one or more apertures 824.

[0379] The cover 800 may include a reflector 820 that, in conjunction with the cover surface 821, may define a channel 822 in which light from the display unit 815 may be provided. The channel 822, in conjunction with the output from the display unit 815, may provide one or more types of lighting effects that may convey information to an end user from a distance. Example lighting effects include color changes, flashing colors according to a pattern, fading in and out relative to a color change or a change from on to off or from off to on, or any combination thereof. Additionally or alternatively, in one embodiment, the configuration of the channel 822 and the display unit 815 may produce a lighting effect having a greater light intensity in the channel 822 near the sidewall portion 870 of the display unit 815 than in an area of ​​the channel 822 that is away from the display unit 815. Fig.64 Graph 817 in the illustrated embodiment shows the light intensity distribution along the channel in conjunction with one configuration of the cover 800 and the display unit 815 .

[0380] According to one embodiment of the present invention, the display unit 815 is Figure 66-Figure 67815 is shown in further detail in . Display unit 815 is similar to display unit 715 described herein, but with several exceptions. Display unit 815 in the illustrated embodiment, in combination with cover 800 and water treatment system 100, can provide a user interface component for operating water treatment system 100. The display unit may include one or more feedback indicators 818, which are similar to feedback indicator 718 of display unit 715, but are arranged differently in a circular manner. Feedback indicator 818 can be configured to convey information about water treatment system 100 (e.g., status information) to an end user. Additionally or alternatively, feedback indicator 818 can be configured to accept user input, such as by capacitive touch sensing or other types of touch-based input, so that an end user can control one or more operations of water treatment system 100.

[0381] Display unit 815 includes one or more of the following components: back cover 850, display unit circuitry 852, housing 854, guide assembly 856, optical cover 858, and decorative assembly 860. These components can be similar in many respects to the correspondingly named components of display unit 715, but modified according to the different shaped housing configuration of display unit 815 relative to display unit 715. For example, guide assembly 856 and display unit circuitry 852 are configured differently (e.g., in a circular arrangement) relative to guide assembly 756 and display unit circuitry 752. Despite the differences in the construction and packaging of these components, the function of guide assembly 856 and display unit circuitry 852 is similar to the corresponding components of display unit 715 in providing light via guide assembly 856 or sidewall portion 870 of housing 854, or both.

[0382] The guide assembly 856 in the illustrated embodiment may include one or more light guides 886 configured to connect to one or more light sources provided by the display unit circuit 852 and direct light therefrom to the optical cover 858. The optical cover 858 may include an optical mask 859 similar to the optical mask 759.

[0383] In the illustrated embodiment, the housing 854 includes an interior space 872 defined by the sidewall 871, the interior space 872 being configured to receive the guide assembly 856 and the display unit circuit 852. The housing 854 may include a rear opening 874, and at the rear opening 874, the rear cover 850 may be connected to the housing 854 to cover the rear opening 874 in the assembled state. For example, the housing 854 may include a recess 853 that is annular around at least a portion of the inner perimeter of the sidewall 871 and is configured to receive the rear cover 850.

[0384] The display unit circuit 852 may include a power supply circuit for supplying energy to the primary light source 862 and the secondary light source 864. The secondary light source 864 in the illustrated embodiment is arranged near the perimeter of the printed circuit board of the display unit circuit 852, and the primary light source 862 may be arranged near the central area of ​​the printed circuit board. In other words, the secondary light source 864 may be closer to the perimeter edge of the printed circuit board than the primary light source 862. Similar to the display unit 715, there may be multiple primary and secondary light sources 862, 864.

[0385] Similar to the display unit 715, the secondary light source 864 can be arranged on the display unit circuit 852 near the side wall portion 870. The primary light sources 862A-862E are shown as being generally evenly distributed around the entire central area of ​​the display unit circuit 852, while the secondary light sources 864A-864D are distributed around a portion of the central area disposed near the side wall portion 870.

[0386] The sidewall portion 870 of the housing 854, shown in phantom for purposes of disclosure, can be at least translucent, and optionally transparent, to light generated from the secondary light source 864 of the display unit 815. Although shown as a portion of the sidewall 871 of the housing 854, the sidewall portion 870 can include any portion of the housing 854, including the entire housing 854. The sidewall portion 870 of the illustrated embodiment can form a lens through which light from the secondary light source 864 can be directed. Similar to the sidewall portion 770 of the display unit 715, the sidewall portion 870 can include a first lens surface 881 and a second lens surface 882.

[0387] The guide assembly 856 of the display unit 815 can be configured so that the primary and secondary light sources 862, 864 can be aligned along an axis that intersects the central axis of the display unit 815.
