Definitions
- This application relates generally to the field of cleaning systems for use with toilets. More specifically, this application relates to cleaning systems configured to dispense cleaning compounds for use in toilets to improve the cleanliness in and around the toilets.
- At least one embodiment of this application relates to a toilet that includes a bowl, a tank, a container, a connector, and a flush valve.
- the tank has a sidewall and a bottom defining a reservoir.
- the container is located inside the reservoir and is configured to contain a chemical compound that mixes with water from a fill valve to form a cleaning compound.
- the connector is configured to couple the container to the sidewall; and the connector includes a bracket coupled to the container, a threaded protrusion that extends from the bracket into a hole in the sidewall of the tank, and a threaded fastener having a threaded body and a head, which is larger radially than the threaded body such that the head contacts an outside of the sidewall in a secured position in which the threaded body threads to the threaded protrusion.
- the flush valve is fluidly connected to the container to introduce the cleaning compound into the bowl through an outlet in the bottom of the tank during a cleaning cycle.

FIG. 17 is a plan view of an exemplary embodiment of a multi-position control for controlling operation of a chemical dispensing system. - Referring generally to the Figures, disclosed in this application are toilets having integrated chemical dispensing systems or assemblies, which are configured to introduce (e.g., deliver, dispense, etc.) a chemistry (e.g., a cleaning compound) into a bowl of the toilet during a cleaning cycle. As discussed below, the cleaning compound includes a chemical compound, which can be mixed with water to dilute the concentration of chemical compound. The water can be supplied by a fill valve of the toilet; and the cleaning compound can be introduced into the bowl through a flush valve of the toilet. By way of example, the systems and methods, as disclosed herein, may be configured to influence (e.g., reduce) scale, slippery, and/or sanitation through the cleaning compound to thereby have improved cleanliness. As used herein, the term “scale” generally refers to mineral deposits (e.g., calcium carbonate, magnesium carbonate, etc.), that collect or build-up on the surfaces of the components of systems, such as toilets. As used herein, the term “slippery” generally refers to coating(s) that may be applied to the surfaces of the components of the systems to influence the coefficient of friction of the surfaces. For example, a non-stick coating, such as a diamon-fusion coating, may be applied to surfaces of the components to reduce the coefficient of friction of the surfaces to which the coating is applied. As used herein, the term “sanitation” generally refers to the application (e.g., introduction, etc.) of anti-microbial chemicals. Thus, the toilets disclosed herein can introduce a cleaning compound to thereby reduce, scale, slippery, and/or sanitation.
- The toilets and methods of this application may be configured to utilize one or more than one compound/chemistry to improve the cleanliness of the toilet. In this application, the terms “chemistry,” “compound,” and “cleaning compound” are used interchangeably to connote the use of a chemical, chemical compound, chemical element, or any combination thereof that is beyond that of mere water. Thus, while the systems described in this application may use water (e.g., to dilute a cleaning compound, for flushing, etc.) and the cleaning compounds may include water, the chemistry/compounds/cleaning compounds include at least one additional chemical (e.g., elements, compounds, etc.) other than water.
-
FIG. 1 illustrates an exemplary embodiment of atoilet 100 including a base 110 (e.g., pedestal, bowl, etc.), a tank 120 (e.g., cistern, etc.) supported by thebase 110, and aseat assembly 116. Thebase 110 is configured to be secured to another object, such as a drain pipe, floor, combination thereof, or any other suitable object. Thebase 110 includes abowl 111 defined by arim 115 of thebase 110 and an internal passageway fluidly connecting thebowl 111 to the drain pipe (not shown). The illustratedseat assembly 116 that includes aseat 117 and aseat cover 118, both of which are pivotally (e.g., rotatably) coupled to thebase 110 through ahinge assembly 119 having one or more pivots (e.g., hinges). Thehinge assembly 119 is shown mounted to therim 115 and rotatably supporting theseat 117 and theseat cover 118. - The
tank 120 shown inFIG. 1 is separate from thebase 110 and supported by an upper surface of a ledge of thebase 110 that is rearward of therim 115. Thus, the illustratedtoilet 100 is commonly referred to as a two-piece toilet. Alternatively, thetank 120 may be integrally formed with the base 110 (e.g., the ledge), which is commonly referred to as a one-piece toilet. It is noted that the elements of the tank assembly described herein may be used with other types of toilets and other types of tanks for toilets. -
FIGS. 2-6 illustrate an exemplary embodiment of atank assembly 102 for use with a toilet, such as the one-piece toilet 100 shown inFIG. 1 . Thetank assembly 102 includes thetank 120, a lid 122 (e.g., tank lid), afill valve 130, aflush valve 140, ashroud 150, and achemical dispensing system 160. Thefill valve 130 is located inside the reservoir and is configured to receive water through an inlet 131 (through the inlet opening 120 d) to selectively fill the reservoir to a high water level HWL. Thefill valve 130 can have any construction. - The illustrated
tank 120 includes one or more sidewalls 120 a and a bottom 120 c that define aninternal reservoir 120 b (e.g., cavity) that is accessible through an open top in thetank 120. The bottom 120 c has aninlet opening 120 d and anoutlet opening 120 e. Ahole 120 f is located in onesidewall 120 a for securing thechemical dispensing system 160 to thetank 120. As shown inFIG. 4 , thehole 120 f is located in arear facing sidewall 120 a and is positioned or located above the high water level HWL and below theshroud 150. - The illustrated
lid 122 is configured to conceal theshroud 150 in a covered position (i.e., positioned or resting on top of thetank 120 covering the open top andreservoir 120 b of the tank). Thelid 122 can be removed from thetank 120 to access theshroud 150, such as to remove theshroud 150, as well as access thechemical dispensing system 160 or part(s) thereof. -
FIGS. 2, 5, and 6 also show aflush handle 126 that is configured to initiate a flush cycle of the toilet. For example, theflush handle 126 can be operatively coupled to theflush valve 140 to open the valve in response to a user of the toilet rotating theflush handle 126 relative to thetank 120. Theflush handle 126 and/or other actuators (e.g., buttons, handles, devices, etc.) can operate thechemical dispensing system 160. - The illustrated
shroud 150 is disposed in and closes off the open top of thetank 120 in an installed position (FIG. 2 ) to conceal thefill valve 130, theflush valve 140, and at least part of the chemical dispensing system 160 (e.g., a container thereof). Theshroud 150 includes abody 151 having an outer profile (e.g., when viewed from above) that complements the shape (e.g., profile) of an inside of thetank 120. The outer profile of thebody 151 can contact the inside of thetank 120. Thebody 151 of theshroud 150 includes one or more holes. As shown best inFIGS. 2 and 5 , thebody 151 includes a through hole 153 (e.g., a first through hole, aperture, opening, etc.) that receives at least one part of the chemical dispensing system 160 (e.g., a container lid thereof). The throughhole 153 is configured (e.g., shaped, sized, etc.) based on the configuration of at least one part of thechemical dispensing system 160. Also shown, a second throughhole 155, which is separate and offset from the throughhole 153, extends through thebody 151 to receive another part of the chemical dispensing system 160 (e.g., amulti-position control 272 thereof). Additional holes can, optionally, be disposed in theshroud 150. By way of example, athird hole 157 can be disposed in theshroud 150 to receive areset control 158 and/or afourth hole 159 can be disposed in theshroud 150 to receive a fastener or indicator (e.g., an illuminated indicator). -
FIGS. 7-16 illustrate an exemplary embodiment of achemical dispensing system 160 that includes acontainer 161 that is located in (e.g., inside, within, etc.) thereservoir 120 b and is configured to contain (e.g., hold, house, etc.) a chemical compound. As noted above, the chemical compound can mix with water to form a cleaning compound. Alternatively, the chemical compound can be used as the cleaning compound with dilution. As shown best inFIG. 3 , aninlet line 135 fluidly connects anoutlet 133 of thefill valve 130 and aninlet 167 of thecontainer 161, and anoutlet line 145 fluidly connects anoutlet 168 of thecontainer 161 with aninlet 141 of theflush valve 140. - The illustrated
container 161 includes abody 162 having a bottom 163 (FIG. 11 ) and a plurality of walls 164 (e.g., sidewalls) interconnected with the bottom 163 and with an open top to define aninternal reservoir 165 in thebody 162. Thus, thereservoir 165 is accessible through an opening in a top of thecontainer 161. As shown best inFIGS. 8-11 , thecontainer 161 includes aflange 166 extending outwardly from an exterior of onewall 164, and the illustratedflange 166 includes two arms that are spaced apart to form a clevis (e.g., clevis shape). Theflange 166 is configured to secure thecontainer 161, as discussed below. - As shown best in
FIGS. 4 and 6 , aconnector 170 is configured to secure or couple thechemical dispensing system 160 to asidewall 120 a of thetank 120. As shown best inFIGS. 8-10 , theconnector 170 includes abracket 171, which is located inside thereservoir 120 b of thetank 120 and is directly coupled to theflange 166 of thecontainer 161 through afastener 169. The illustratedbracket 171 has abody 172, which is shown generally planar, and two spaced apartarms 173 extending from thebody 172 to form a clevis, and thefastener 169 extends through one of the two spaced apart arms (e.g., the top arm) and threads to the other of the two spaced apart arms (e.g., the bottom arm). Accordingly, thecontainer 161 and thebracket 171 can pivot relative to one another about thefastener 169. Thebracket 171 includes a threadedprotrusion 175 that extends from thebody 172 of thebracket 171 in an opposite direction as thearms 173 to engage ahole 120 f in asidewall 120 a of thetank 120 when coupling thecontainer 161 to thetank 120. Thus, thearms 173 and the threadedprotrusion 175 are on opposite sides of thebody 172. The illustrated threadedprotrusion 175 includes internal threads and has a hexagonal outer shape, which can dictate orientation and/or prevent relative rotation between the threadedprotrusion 175 and thehole 120 f in thesidewall 120 a of thetank 120 if thehole 120 f has a complementary shape. The illustratedhole 120 f is located above the high water level HWL in thereservoir 120 b and is located below theshroud 150. - The illustrated
connector 170 also includes a threadedfastener 177 having a threadedbody 178 and ahead 179. The threadedbody 178 has external threads that thread to the internal threads of the threadedprotrusion 175. Thehead 179 is larger radially (e.g., diametrically) than the threadedbody 178, such that thehead 179 contacts an outside surface of thesidewall 120 a (being secured to) in a secured position, in which the threadedbody 178 threads to the threadedprotrusion 175. The illustratedhead 179 has a hexagonal outer shape to facilitate rotation, such as using a wrench, other tool, or by hand. Thus, to couple thecontainer 161 to thetank 120, the threadedprotrusion 175 is inserted into thehole 120 f in thesidewall 120 a (with thebracket 171 coupled to the container 161), so that thebody 172 of thebracket 171 abuts or is adjacent to the inside surface of thesidewall 120 a, then the threadedfastener 177 is threaded to the threadedprotrusion 175 from outside thetank 120. The threadedfastener 177 can be turned until thesidewall 120 a is securely clamped between thehead 179 and thebody 172. - As shown best in
FIGS. 7 and 11 , thechemical dispensing system 160 includes avalve assembly 270 that is configured to control a flow rate of water into thecontainer 161 from thefill valve 130. The illustratedvalve assembly 270 includes ahousing 271 that is operatively coupled to thecontainer 161 and includes theinlet 167 fluidly connected to theinlet line 135. Located in thehousing 271 is a valve that is operable in two or more positions corresponding to two or more settings of the valve, in which a flow rate of water into thecontainer 161 form theinlet 167 is controlled. Thus, the flow rate of water is different in each position (e.g., setting) of the valve. Further, the valve can be a ball valve or any other suitable type of valve. - A
multi-position control 272 extends above thehousing 271 and is operably coupled to the valve, so that thecontrol 272 changes (e.g., switches) operation of the valve between the two or more settings. The illustratedcontrol 272 is configured as a rotary knob that can be rotated into each position. On the knob is anindicator 275 that aligns withindicators 152 in the shroud 150 (FIG. 5 ) to inform a user as to the setting of the valve. The illustrated embodiment inFIG. 5 includes threeindicators 152, which can include an off position and two different cleaning settings (e.g., a first concentration of chemistry/chemical compound, a second concentration of chemistry/chemical compound) or three different cleaning settings.FIG. 17 illustrates an exemplary embodiment of a four position/setting chemical dispensing system. Themulti-position control 272 can be toggled (e.g., rotated) between afirst position 152 a shown as an “off” setting, in which the chemical dispensing system dispenses only water without a chemistry, asecond position 152 b shown as a “−” setting, in which the chemical dispensing system dispenses a first concentration (e.g., a reduced concentration below that of a nominal concentration), athird setting 152 c , in which the chemical dispensing system dispenses a second concentration (e.g., a nominal concentration), and afourth setting 152d shown as a “+” setting, in which the chemical dispensing system dispenses a third concentration (e.g., an increased concentration above that of a nominal concentration). Themulti-position control 272 is accessible with thelid 122 removed from thetank 120 and with the shroud (e.g., the shroud 150) in place. As shown best inFIGS. 2 and 5 , thecontrol 272 nests within and is accessible through the throughhole 155 in theshroud 150. The throughhole 155 is shown separate from the throughhole 153 that receives the container lid and/or the throughhole 157 that receives thereset button 158. - As shown in
FIG. 11 , the outlet from thevalve assembly 270 is fluidly connected to an inlet of a diffusingtube 273, which is illustrated as a U-shaped tube having an outlet that is located at the end opposite the inlet and is fluidly connected to theoutlet 168 and theoutlet line 145. The diffusingtube 273 has a plurality of spaced apartopenings 274 located between the inlet and the outlet of the diffusingtube 273, and the part of the diffusingtube 273 having theopenings 274 is disposed under a fluid level of thecontainer 161 so that water received through theinlet 167 can flow out theopenings 274 to mix with the chemical compound in thereservoir 165. The cleaning compound can flow back into theopenings 274, such as during a flush cycle and/or a cleaning cycle, and through theoutlet 168 to theflush valve 140. - The
chemical dispensing system 160 includes acontainer lid 180 that detachably (e.g., removably) couples to thecontainer 161 in a secured position (FIGS. 7 and 8 ) and allows access to thereservoir 165 of thecontainer 161 in a removed position (FIG. 11 ).FIGS. 12-16 illustrate an exemplary embodiment of acontainer lid 180 that includes abase 181, a slider 185 (e.g., sliding member), aresilient member 190, and acam lever 192. - The
base 181 is disposed on an upper end of the wall(s) 164 of thecontainer 161 in a coupled position, as shown inFIGS. 3, 4, 7, and 8 . Thebase 181 has a shape that complements the throughhole 153 in theshroud 150 and is configured to cover the open top in thecontainer 161. The illustratedbase 181 has a flat bottom, which rests on thecontainer 161 in the coupled position, a throughbore 182 extending through thebase 181, and a recess 183 (e.g., cutaway, pocket, etc.) in the top. - The illustrated
slider 185 includes anupper portion 186, which is fitted in the throughbore 182 of thebase 181, and alower portion 187, which extends down from theupper portion 186 and is configured to fit in the opening (e.g., the open top) in thebody 162 of thecontainer 161. As shown, an outer profile of theupper portion 186 of theslider 185 complements a profile of the throughbore 182 in thebase 181. Thelower portion 187 has a lip 188 (FIG. 12 ) that extends outwardly from an outer surface of the lower portion. Thelip 188 can extend around the entire periphery/profile of thelower portion 187 or a portion thereof. - The
resilient member 190 is disposed around at least part of thelower portion 187 of theslider 185 between thelip 188 and thebase 181. The term “resilient” denotes that the member is compliant and/or is able to deform elastically under loading and can recover after the load is removed. The illustratedresilient member 190 is ring shaped, has a generally rectangular cross-section, and extends around thelower portion 187. - The cam lever 192 (e.g., cam member) is rotatably coupled to the
slider 185 about a pivot axis PA, so that thecam lever 192 can rotate relative to theslider 185 between a non-locking position (FIGS. 12, 14, and 16 ) and a locking position (FIGS. 13 and 15 ). The illustratedcam lever 192 includes alever 193, which has a generally a flat rectangular shape, and first andsecond legs 194, which are spaced apart and extend from thelever 193. Thus, thelever 193 and first andsecond legs 194 form a clevis shape that wraps around theupper portion 186 of theslider 185. Eachleg 194 is rotatably coupled to the slider 185 (e.g., the upper portion 186) about the pivot axis PA and includes acam surface 195, which is offset from the pivot axis PA (e.g., opposite from thelever 193. - Rotation of the
cam lever 192 relative to thebase 181 and theslider 185 from the non-locking position to the locking position moves the slider 185 (e.g., in an upward direction inFIGS. 12 and 16 ) relative to the base 181 through thecam surface 195 contacting thebase 181, such that thelip 188 biases theresilient member 190 outwardly from a clearance fit into an interference fit with thewall 164 of thebody 162 of thecontainer 161 to secure thecontainer lid 180 to thecontainer 161 in the secured position. The term “clearance fit” means that the member (e.g., resilient member 190) is no larger than the size of the opening (e.g., in the body 162), so that thecontainer lid 180 is removable from thecontainer 161. For example, theresilient member 190 is sized to fit through the opening. The term “interference fit” means that the member (e.g., resilient member 190) is larger than the size of the opening (e.g., in the body 162), so that thecontainer lid 180 is prevented from being removed from thecontainer 161. For example, theresilient member 190 is sized to prevent being fitted through the opening. Thus, rotation of thecam lever 192 toward the locking position causes the pivot axis PA and coupledslider 185 to move (e.g., lift, rise, slide upward) relative to the base 181 through contact between thefirst cam surface 195 of thefirst leg 194 and a first part of thebase 181 and between thesecond cam surface 195 and a second part of thebase 181. In the locking position, thecam lever 192 nests with the upper portion of theslider 185 and nests within therecess 183 of thebase 181. The illustratedcam lever 192 complements the base 181 by forming a substantially planar top between a top of thecam lever 192, a top of theupper portion 186 of theslider 185, and a top of thebase 181, which is on an opposite side of theslider 185 from thecam lever 192. - The
resilient member 190 can be configured to form a fluid (e.g., water, liquid) tight seal between thebody 162 of thecontainer 161 and thecontainer lid 180 in the secured position. An outer profile of thelower portion 187 of theslider 185 can be shaped, either alone or in combination with theresilient member 190, to complement a profile of the open top in thebody 162 of thecontainer 161. - The
container lid 180 advantageously provides a seal with thecontainer 161 when secured thereto to retain the chemistry within thereservoir 165 of thecontainer 161, and thecontainer lid 180 can be removed and reattached quickly and easily (e.g., without fastening or screwing the lid). Also, by nesting thecontainer lid 180 with theshroud 150, if provided, thelid 180 can be removed without removing theshroud 150. Thus, the clean aesthetics can be maintained while replacing the chemistry in thereservoir 165. - The
toilet 100 can include one or more indicators that identify (e.g., indicate) any useful information to a user of thetoilet 100. Thetoilet 100 can be configured to connect to a remote electronic device, such as a smart phone, a tablet, etc., through a wireless method (e.g., Bluetooth), and an indicator may indicate connectivity information regarding the status of the cleaning system, such as whether the cleaning compound is low in level and/or in concentration, and/or information regarding timing of the last and/or next cleaning cycle. Any number of indicators can be located, for example, on theshroud 150, thelid 122, or on other components of thetoilet 100. - It is noted that the
toilet 100 having thechemical dispensing system 160 integrated with theshroud 150 can be employed on other types of toilets, included inside of shroudless tanks. Thesystem 160 can still be operatively coupled to thesidewall 120 a of thetank 120, as well as having the configuration otherwise described above. However, thecontainer 161 of thesystem 160 would be visible with or with the container lid coupled thereto with shroudless tanks. - It is further noted that the
container 161 can hold a solid chemical compound (e.g., pellets, tablets, discs, pucks, etc.) while allowing water to pass through to mix with the solid chemical compound as it dissolves. For example, water enters the reservoir of thecontainer 161 through theopenings 274 in the diffusingtube 273 and dissolves the solid chemical compound to form cleaning compound. - It is noted that the
toilet 100 can be configured to connect to a remote electronic device, such as a smart phone, a tablet, a computer, a remote control, or any other suitable device. Thetoilet 100 and the remote electronic device can connect through a wireless method, such as Bluetooth or any other wireless method, to control operation of thetoilet 100 from the remote device. For example, the device can receive data regarding thechemical dispensing system 160 in thetoilet 100, which can include, but is not limited to data involving level and/or concentration of chemistry remaining in the container, frequency of cleaning cycles, estimated time until the chemical compound is completely used up, recommended date for next cleaning cycle, estimated remaining life (e.g., days, power, etc.) of any batteries in the system, whether any components of the system are not functioning properly, as well as any other useful information. By way of example, an application or app (e.g., phone app) can be used to receive this data from thetoilet 100 and send push notifications to the user regarding any of the data, such as alerts. Additionally, the remote electronic device can be configured to control operation of the toilet remotely, such as to activate a cleaning cycle from a remote location. - The toilets described in this application can be configured to utilize chemistry to advantageously help clean (e.g., up to a level just below disinfection) or help maintain the cleanliness longer than toilets not having the improved chemistry. As non-limiting examples, the chemistries disclosed herein may advantageously help prevent the formation of scale, remove scale that has formed, prevent or remove biofilm, prevent or mask odors, and/or sanitize components of toilets or other devices disclosed in this application. The toilets utilizing the improved chemistry may be able to go for one to six months (e.g., eight weeks) or longer without having to be cleaned (e.g., before the build-up of deposits). More specific examples of chemistry/cleaning compounds are described below in greater detail.
- The chemistry/cleaning compounds can be delivered to specific components of the toilets (e.g., bowl, seat, tank, and/or trap, etc.) alone or mixed with another compound or element. The compounds may be provided into the toilets, such as prepared external to the toilet and introduced into the toilet for use therein. The compounds may be generated in the toilets, such as generated within systems and/or subsystems of the toilets for use therein. For example, chemical/compound generators may be employed by a toilet and/or an accessory to produce a cleaning compound used to clean the toilet and/or accessory.
- The systems/toilets can introduce one or more than one cleaning compound into or onto a component (e.g., element), surface, and/or feature of the system/toilet. As discussed above, one or more cleaning compounds can be introduced into or onto the bowl, such as from a reservoir in the tank, and/or any other part of the toilet. As one such example, a toilet may be configured to introduce hydrogen peroxide (H2O2) into the bowl of the toilet to help clean the internal surfaces that come into contact with liquid and solid waste. In addition to H2O2, chlorines and peracedic acid (PAA) are additional non-limiting examples of chemicals/compounds that may be used with the toilets and methods of this application. Some additional non-limiting examples of chemicals/compounds that may be used with the systems and methods of this application include (but are not limited to) polyphosphates (e.g., sodium hexametaphosphate (SHMP), tetrapotassium pyrophosphate (TKPP), etc.), low pH acids (e.g., hydrogen chloride (HCL), dihydrogen phosphate (H2PO4), trisodium phosphate (TSP), ethylenediaminetetraacidic acid (EDTA), and compounds thereof, as well as other acids and/or sequestering agents. These chemicals/compounds may be most beneficial in, for example, preventing and/or removing scale. Yet other examples of chemicals/compounds that may be used with the systems of this application include (but are not limited to) didecyldimethyl ammonium chloride (DDAC), H2O2, sodium hypochlorite (NaOCl) such as bleach, PAA, triclosan, formic acid, TSP, and compounds thereof, as well as other disinfectants (e.g., quaternary disinfectants) and biocides. These chemicals/compounds may be most beneficial in, for example, preventing and/or removing biofilm. It is noted that other chemicals/compounds may be used in the systems and methods disclosed in this application, and any such chemical/compound disclosed may be used with any system and/or method disclosed.
- The chemicals/compounds can take various forms, such as liquids or solids. One example is in the form of tablets or discs. Another example is in the form of phosphate beads, which may be spherical (e.g., 12.7-25.4 mm in diameter) or may have any suitable shape. Another example includes a shell (e.g., glass shell) that houses a chemical (e.g., phosphate) inside and is released or brought into contact with a diluent, such as through an opening. The concentration of the chemical may be relatively high, so that it can last over a long period of time (e.g., about one year) without having to be replaced.
- The toilets may include a system that generates a chemical/compound, such as one of those disclosed above. For example, a generator that produces H2O2, such as from oxygen (e.g., in air) and water from a water source can be employed. Thus, a chemical/compound generator can be located within the toilet (e.g., the container) to produce the cleaning compound. For example, a generator may be configured to produce a chemical (e.g., H2O2) that is diluted to 30 ppm (parts per million), such as with water or other suitable diluent. According to one example, a generator is configured to produce a chemical that is diluted to 100 ppm.
- The systems for introducing a cleaning compound can be built into the toilet (e.g., an OEM produced toilet) or may be an “add-on” system that can be installed onto a traditional system and/or toilet (after its manufacture, such as an “after-market” system or assembly) to improve the cleanliness of the traditional system and/or toilet.
- The systems and methods described in this application may include an electrochemical generator or method of electrochemical generation, which may involve using oxygen, water, and an electrical current to generate a chemical/compound.
