[0033] The following embodiments include apparatus and techniques for disinfecting and reducing scale buildup inside and / or in one or more water flows associated with a toilet tank. The water treatment equipment may be placed with the toilet tank to treat water as it enters the tank through one or more fill valves. In other examples, the water treatment equipment may be placed in a straight line with a water supply device or inlet pipe that supplies water to one or more fill valves.

[0034] The following embodiments include equipment and techniques for reducing, mitigating, or preventing scale buildup in plumbing and / or disinfecting plumbing equipment. Plumbing equipment may include pipes, faucets, bathtubs, showers, water softeners, water heaters, toilets, or other fixtures. The term "plumbing fixture" refers to a device that connects to a plumbing system in a house, building, or other structure. The term "bathroom fixture" may more specifically refer to individual types of plumbing fixtures found in a bathroom. The term "kitchen fixture" may more specifically refer to individual types of plumbing fixtures found in a kitchen.

[0035] Figure 1 The illustration shows an exemplary toilet (bathroom fixture) for use with a water treatment system. (See reference...) Figure 1 An exemplary embodiment of the present disclosure illustrates a toilet 1100 with a water treatment system. The toilet 1100 may include a water tank (e.g., a container, reservoir, etc.), shown as tank 101, and a base (e.g., a base, bracket, support, etc.), shown as base 1104. Tank 101 may be coupled to and supported by base 1104, which may be positioned on the floor. In some embodiments, tank 101 and base 1104 may be formed as a single component. In other examples, tank 101 may be mounted on or within a nearby wall. Tank 101 is configured to receive water (e.g., via a fill valve of toilet 1100) and store water between flushes. Base 1104 includes a bedpan 1105 and may be configured to receive water from tank 101 to flush the contents of bedpan 1105 into a sewer pipe. In some embodiments, the base 1104 may be mounted on the wall of the bathroom, and the toilet 1105 may be configured to receive water from a fluid supply source (e.g., a household water supply).

[0036] The toilet bowl 1105 of the base 1104 includes a sump (e.g., a container) and a drain outlet, wherein water and waste are collected in the sump until removed through the drain outlet (e.g., when the contents of the toilet bowl 1105 are flushed into a sewer, septic tank system, or other sanitation system). The toilet 1100 further includes a waste passage that is fluidly connected to the toilet bowl 1105 via the sump. The waste passage fluidly connects the sump to the drain outlet.

[0037] The actuator 14 or flushing mechanism may be a button configured to be activated when pressed (or pulled) a predetermined distance or touched; it may also be a lever configured to be activated when rotated a predetermined angular stroke; or it may be any suitable device configured to be activated based on user input.

[0038] It should be noted that the shape and construction of the tank, base, seat assembly, and internal components (including the drain passage and other features) may differ from the examples shown and described herein, and the examples disclosed herein are not intended to be limiting. It should be noted that the various components of the toilet may be made of enamel. It should be noted that the various components of the toilet may be made of polymer materials and / or subjected to secondary injection molding, or otherwise fixed to the toilet. For example, it should be noted that although the tank 101 of the illustrated toilet 1100 is formed separately from the base 1104, and the tank is subsequently attached to the base, the tank may also be integrally molded with the base to form a monolithic structure. In other words, the toilet may be a one-piece design, a two-piece design, or have any suitable construction. The toilets disclosed herein may have a wide variety of skirt toilet constructions, all of which are intended to be covered herein. Therefore, the following description of various toilet features is intended only to illustrate a few examples according to this disclosure, and the reader of this specification should understand that similar concepts or features may be included in a variety of other examples.

[0039] Water tank 101 may include an inlet configured to receive water from a water supply device, such as water from a hose (e.g., a line, pipe). Water tank 101 may also include an inlet valve assembly or other device configured to control the flow of water from the water supply device into the tank through the inlet. A floating device may be provided within water tank 101 for controlling the inlet valve assembly, for example, opening the valve after an operating cycle to refill the container of water tank 101, and closing the valve when the water in the container reaches a preset volume or height. Water tank 101 may also include an outlet configured to transfer (e.g., direct) water stored in the container of water tank 101 to base 1104 when actuator 14 is activated. Base 1104 may include a toilet bowl 1105. Water tank 101 may include an outlet valve assembly or other device configured to control the flow of water from water tank 101 into base 1104 through the outlet.

[0040] The base 1104 (or base) of the toilet 1100 may include a wall of any suitable shape configured to form a toilet bowl 1105 with an opening formed by an upper edge at the top of the opening. The base 1104 may also be configured to include one or more walls of different shapes that together form the toilet bowl, which has an opening formed by an edge. The wall of the base 1104 may extend downward and / or rearward from the toilet bowl 1105 to form a lower portion configured to support the base 1104 and the toilet 1100. The lower portion may be formed by an end of the wall (e.g., a lower edge) or may include components extending generally horizontally from one or more ends of the wall. A flush valve assembly controls the flow of water from the tank 101 to the base 1104. The toilet 1100 may also include a gasket or seal disposed between the tank 101 and the base 1104 to prevent leakage. For example, a gasket can be placed between the outlet of the water tank 101 and the inlet of the base 1104 to prevent leakage between the water tank and the base 1104.

[0041] The base 1104 can also attach the seat assembly 17 to the base 1104 of the toilet 1100. For example, the top member may include one or more openings, each configured to receive fastening devices (e.g., bolts, screws, etc.) to engage (e.g., attach) the seat assembly 17 to the top member of the base 1104. As another example, the top member may include one or more fastening devices (e.g., bolts, embedded nuts, etc.) integrally formed therein (i.e., already provided for connection or attachment to the base 1104), wherein the fastening devices can be used to engage or secure at least a portion of the seat assembly 17 to the base 1104. The seat assembly 17 may include a hinge, a hinge seat configured to receive fasteners, a seat ring coupled to the hinge, and a cover coupled to the hinge.

[0042] The toilet bowl 1105 of the base 1104 can be configured to include a receiving cavity (e.g., a sump) and an outlet, wherein water and waste are collected in the receiving cavity until removed through the outlet (e.g., when actuator 14 is activated). The base 1104 may also include an internal channel (e.g., a drain channel) that connects the outlet or drain of the toilet bowl 1105 to a drain pipe or sewage pipe. The channel or sewage channel generally includes a first portion, a second portion, and a weir separating the first and second portions. The first portion of the channel may extend from the outlet of the toilet bowl 1105 at an upwardly inclined angle to the weir. The second portion of the channel may extend downward from the weir to an outlet device (e.g., a drain pipe or sewage pipe).

[0043] Between operating cycles (e.g., flushing cycles) of the toilet 1100, water (and waste) is collected in the first part of the drain channel (besides the container in the toilet bowl), whereby a weir prevents water from passing through the weir and into the second part of the drain channel. A flushing cycle can be initiated when actuator 14 is activated. Activating the actuator allows more water to be discharged into the toilet bowl 1105 in the base 1104, thereby generating a flushing action and removing waste through the drain pipe. The flushing cycle may include the generation of a siphon to assist the flushing action and waste removal.

[0044] The seat assembly 17 may include a cover member 18 (e.g., a lid), a seat member (e.g., an annular member), and a hinge. The seat member may be configured to include an annular member surrounding an opening, wherein the annular member provides a seat surface for the user of the toilet 1100. The seat member may also be pivotally coupled (e.g., attached) to the hinge, wherein the seat member may rotate (or pivot) about the hinge, for example, between a first lowered or seated position and a second raised or upright position. The cover member 18 may be configured as circular, elliptical, or any other suitable shape. Typically, the profile or shape of the outer surface of the cover member will be configured to match (i.e., substantially similar to) the profile of the outer surface of the seat member to improve the aesthetics of the seat assembly and the toilet. The cover member 18 may also be coupled to the hinge, wherein the cover member may rotate (or pivot) about the hinge, for example, between a first lowered or lowered position and a second raised or upright position. The cover member 18 can be positioned on top of the seat member when in the lowered position to cover the opening of the seat member and conceal the interior of the toilet bowl 1105 of the base 1104. The cover member 18 can be configured to rest against the outer surface of the tank 101 when in the upright position, thereby keeping the cover member 18 in an upright position so that the user can sit on the seat member.

[0045] Figure 2 An exemplary water tank 101 is illustrated, including a lid or cover 128, a base or frame 131, a flush valve 121, a fill valve 123, and a water treatment device 125 inside the water tank 101. The water treatment device 125 may be integrated with or otherwise coupled to the fill valve 123. The water treatment device 125 may be integrated with or otherwise coupled to the flush valve 121. Additional, different, or fewer components may be included.

[0046] Figure 3 An exemplary water tank 101 is illustrated, which includes a lid or cover 128, a base or frame 131, a flush valve 121, a fill valve 123, and a water treatment device 125. A water supply line 127 (inlet line) supplies water from the water supply device to the fill valve 123. Additional, different, or fewer components may be included.

[0047] The following embodiments include those applicable to Figure 2 and / or Figure 3 This is an exemplary embodiment of the water treatment apparatus 125. Each of the water treatment apparatus 125 can be combined with a cleaning compound dispensing device.

[0048] Beads or templates aid crystallization Water treatment device 125 may include a pretreatment unit utilizing bead-assisted crystallization (TAC). The TAC beads are configured to neutralize the molecular charge of one or more elements that cause scale buildup. Exemplary elements include calcium and magnesium. The neutralized elements do not adhere to the water tank 101, fill valve 123, and flush valve 121. Instead, the neutralized elements flow through the toilet bowl and sump as part of the flushing cycle.

[0049] Two chemicals in the saturator Water treatment equipment 125 may include inflow water treatment using two chemicals. One example includes a compound formulation of chlorine dioxide (ClO2) blocks and polyphosphates. Another example includes a compound formulation of chlorine dioxide (ClO2) blocks and citric acid.

[0050] Magnetic scale filter Water treatment device 125 may include an inflow magnetic filter. Water treatment device 125 may include at least one storage chamber for material to be filtered from water. Water treatment device 125 may include at least one magnet in contact with the water flow. An exemplary magnet may be formed of neodymium and generate a magnetic field of at least 10,000 gauss. Water treatment device 125 may utilize the principle of electrolysis.

[0051] Pretreatment using magnetic equipment The water treatment device 125 may include a clamping device that clamps onto the water supply pipe 127. The clamping device may include one or more springs that apply force to hold the water treatment device 125 to the water supply pipe 127. Inside the water treatment device 125 are a plurality of magnets arranged in a predetermined pattern to reduce biofilm and mineral scale from inside the water supply pipe 127.

[0052] The water treatment device 125 may include one or more internal diverters configured to provide force or guidance to the flow of water through the water supply conduit 127. The one or more internal diverters may include at least one helical drive that induces vortices in the water flow to separate particles from the flow. The water treatment device 125 may cause particles to break up in the water flow.

[0053] In one example, the water treatment device 125 may include two strong magnets positioned on opposite sides of the water supply pipe 127. Water passes through the uniform magnetic field between the two magnets. The magnetic field is configured to alter the structure of sediments formed in the water, thereby mitigating or preventing adhesion to the water tank 101, the filling valve 123, and the flushing valve 121.

[0054] Ion exchange filter Water treatment device 125 may include an ion exchange filter configured to inhibit scale buildup. Water treatment device 125 may include an ion exchange resin configured to replace charged ions in water with ions (e.g., H+ and OH-). The resin may be formed into resin beads with attached hard water particles.

[0055] Alloy scale reduction technology Water treatment device 125 may include a multi-element alloy configured to release free electrons. Water treatment device 125 can reduce the amount of electrons released from one or more elements (e.g., by magnesium (Mg)). 2+ ) and calcium (Ca 2+ Scale formed.

[0056] Nanobubble and / or microbubble technology The water treatment device 125 may include a nanobubble generator. The nanobubble generator may be configured to convert gas in the water into nanobubbles (e.g., bubbles with a diameter of less than 50 micrometers), which are configured to reduce or prevent scale buildup in the water supply pipe 127, the fill valve 123, or other places in the water tank 101.

[0057] Processing device 125 can generate microbubbles. The term microbubble can be used to describe bubbles with a diameter of approximately 1 to 100 μm. Additional bubbles, such as those with a diameter of 100 to 1000 μm or larger, may be present during microbubble generation. Microbubbles can have a lifetime before imploding in water. In one example, the lifetime can be at least 1 minute. In other examples, the lifetime is in the range of approximately 2 to 4 minutes. In one example, a pressurized airflow is dissolved into the liquid using a nozzle to generate bubbles according to the principle of cavitation. This nozzle can be a venturi tube. In cavitation, the static pressure of the liquid is lower than its vapor pressure, resulting in the formation of a vapor-filled chamber. Vapor pressure is the pressure at a specific temperature in thermodynamic equilibrium with other phases (liquid and solid phases). In another example, microbubbles are formed by ultrasound to introduce cavitation into the liquid. In yet another example, microbubbles are formed by shear force. A low-pressure airflow is provided, and shear force is used to break the bubbles into the liquid. The shear force can be vibration provided by fluid oscillation or other methods.

[0058] Microbubbles offer a variety of benefits in a range of applications. Some of these benefits are in water treatment. Some benefits may include improved feel, texture, and appearance of water. Water with microbubbles may feel silky to the touch and may increase humidity levels when in contact with the human body (e.g., skin and hair). Furthermore, microbubbles can enhance water's surface cleaning, dirt removal, oil removal, and makeup removal capabilities. Water with microbubbles can help remove limescale buildup on surfaces.

[0059] In some examples, microbubbles undergo cavitation, leading to implosion that releases hydroxyl radicals and causes physicochemical transformations in the water. In other examples, microbubbles possess electrostatic charges on or associated with their surfaces, allowing their presence to process or otherwise influence the water prior to their eventual implosion. The electrostatic charge on the microbubbles can be negative.

[0060] The bubble generating device 125 may include at least one electrical input to a power source and at least one air input to an air source (e.g., a pump). The bubble generating device 160 may receive commands from the controller 100. The controller 100 may instruct the generating device 160 when to start bubble generation (e.g., a start command) and when to stop bubble generation (e.g., a stop command). Commands from the controller 100 may include a size or size range from the generating device 160. The generating device 160 may adjust parameters of the bubble generation process. In one example, the parameter is the magnitude of the shear force used for bubble generation. In one example, the parameter is the flow rate of the airflow used to generate microbubbles. In one example, the parameter may be the amplitude of vibration or fluid oscillation.

[0061] electric field suppressor Water treatment equipment 125 may include an electric field generator configured to mitigate or prevent scale buildup in water supply pipes 127, filler valve 123, or other locations in water tank 101. The electric field generator is configured to generate an oscillating electric field within the water flow. The oscillating electric field may have a low frequency tuned for one or more elements or particles in the water flow. The oscillating electric field can prevent or otherwise alter the way elements (e.g., scale or calcium) bind together or aggregate. In other words, the oscillating electric field can prevent elements from clumping in the water and / or inhibit the tendency of elements to adhere to pipe surfaces or other pipe fitting surfaces.

[0062] acid filter Water treatment equipment 125 may include an acid filter configured to lower the pH of water flowing through supply pipe 127 or in water tank 101. A more acidic water flow increases the solubility of minerals in the water, thereby reducing scale buildup.

[0063] Radio frequency anti-scaling technology The water treatment device 125 may include a radio frequency (RF) generator configured to generate pulsed radio frequency signals. These signals travel through the water supply pipes and facilitate chemical reactions that cause mineral ions to bind in a suspended state rather than adhere to surfaces.

[0064] Figure 4 Another example of electronically controlled flush valve 121 is illustrated. A float F or other sensor provides sensor data indicating the water level in tank 101 to controller 100. Controller 100 issues commands to flush plate V or an actuator coupled to flush plate V. The actuator may include a motor or a solenoid. Controller 100 determines whether the water level is below a predetermined threshold (e.g., the threshold may be a measurable minimum water level). Controller 100 may keep flush plate V of flush valve 121 open until the predetermined threshold is reached. When the predetermined threshold is reached, controller 100 may close flush plate V.

[0065] In another example, the flushing plate V can be replaced by a pump. Controller 100 instructs the pump to draw water from tank 101 until a predetermined threshold is reached. When the predetermined threshold is reached, controller 100 can shut off the pump.

[0066] The controller 100 can also communicate with the disinfection system 102. The disinfection system 102 can be implemented according to any of the following embodiments. The controller 100 can send instructions or commands to the disinfection system 102. For example, when the controller 100 has determined that the water in the tank 101 has been completely emptied, the controller 100 can instruct the disinfection system 102 to disinfect the interior of the tank 101. The disinfection dispenser 102 is configured to dispense disinfectant material into the toilet tank 101 and into at least one disinfection channel extending from the drain outlet of the toilet tank to the base for the toilet.

[0067] Although described and illustrated in the context of toilet tanks, the disinfection system 102 can be implemented in toilet bowls, drain lines for toilets, drain lines for washrooms, whirlpool tubs, garbage disposals, sinks, fruit / vegetable washers, fragrance dispensers, humidifiers, or other devices.

[0068] For example Figure 4As shown, the flush valve 121 may include any of the water treatment apparatus 125 (or other water treatment apparatus described herein). In some examples, both the filling valve 123 and the flush valve include the water treatment apparatus 125, and in some examples, the water treatment apparatus 125 is omitted from the filling valve 123. The water treatment apparatus 125 of the flush valve 121 may be a removable filter cartridge for refilling with TAC beads or other materials. The water treatment apparatus 125 can be locked in and out of position with a quarter turn. The water treatment apparatus 125 can slide vertically relative to the flush valve 121 for removal and replacement.

[0069] Figure 5A , 5B Figure 5C illustrates an exemplary three-view diagram of a polyphosphate container 200. The polyphosphate container 200 includes a hook 203, a support arm 204, a cavity 206 or body, and a cap 205. The hook 203 is configured to connect a toilet tank and the container 200. Additional, different, or fewer components may be included.

[0070] Cavity 206 may include one or more beads 201. Beads 201 may be formed from soluble compounds or other types of soluble substances. Beads 201 may include at least one polyphosphate comprising a plurality of phosphate units linked by shared oxygen atoms. The polyphosphate may be a salt or an ester. The polyphosphate beads 201 may be template-assisted crystallization (TAC) beads. TAC beads are configured to neutralize the molecular charge of one or more elements that cause scale. Exemplary elements include calcium and magnesium.

[0071] Cavity 206 may include openings 202. Openings 202 may be spaced apart based on the size (e.g., diameter) of beads 201. Beads 201 may be visible through openings 202 when they are installed or before they are substantially dissolved. That is, beads 201 may be nested within openings 202. In other words, the dissolved compound is spherical and aligned with openings 202.

[0072] Opening 202 allows water to freely flow from the toilet tank into cavity 206 and from cavity 206 into the toilet tank. One or more of openings 202 may be specified based on the layout or location allowing water to flow into cavity 206, and another opening 202 may be specified based on the layout or location allowing water to flow out of cavity 206. For at least one opening 202, water flows into cavity 206 at one time, and water and dissolved compounds leave or flow out of cavity 206 at another time.

[0073] Cavity 206 may include a large opening or a top opening for loading beads 201 into cavity 206. The top opening may be selectively covered by a cap 205. Cap 205 may be removed from container 200 to load beads 201. Cap 205 may be partially removable (e.g., permanently engaged at a hinge on one side of the top opening) or fully removable. Caps 205 may be included on both sides of polyphosphate container 221. The openings for cap 205 are multiple openings submerged in toilet tank 250.

[0074] Figure 6A and Figure 6B The illustration shows a toilet tank 250 that houses and supports an exemplary polyphosphate container 200. The toilet tank 250 includes a tank body 210 configured to house and support water for flushing the toilet. The toilet tank 250 includes a flush handle 214, a fill valve 421, a float 420, a flush valve 212, and a conduit 213 connecting the fill valve 421 and the flush valve 212. The toilet tank 250 can be fastened or attached to a toilet base or a toilet seat including a toilet bowl. Additional, different, or fewer components may be included.

[0075] When the water level falls below a threshold level (e.g., after water has been released for flushing), the float 420 rests on the water surface and is lowered to engage or disengage the fill valve 421. With the fill valve 421 open, water is supplied to the toilet tank body 210. The toilet tank 250 is refilled above the threshold level, and the fill valve 421 is closed. Later, when the flushing cycle restarts, for example by operating the flush handle 214, the flush valve 212 is opened to release water from the tank body 210 into the toilet bowl, thereby flushing and emptying the contents of the toilet bowl. Figure 6A and Figure 6B In this embodiment, the polyphosphate container 200 is separate from the flushing valve 212 and filling valve 421 system. Water typically circulates through the tank body 210. That is, when water is supplied through the filling valve 421, there is a small flow that distributes the dissolved substance from the polyphosphate container 200 to other parts of the tank body 210. Figure 6A and Figure 6B The system can be referred to as a passive polyphosphate system because the polyphosphate container 200 is not connected to the flush valve 212 or the fill valve 421. One or more embodiments described below can be considered as an active polyphosphate system because the polyphosphate container 200 is connected to the flush valve 212, the fill valve 421, or both.

[0076] Figure 7AAnother embodiment of a polyphosphate container 221 is illustrated, configured to reduce limescale buildup in a toilet bowl. The polyphosphate container 221 has a U-shape that fits into a body 206. The body 206 can take other shapes (e.g., substantially circular, S-shaped, linear, or V-shaped). Beads 201 (polyphosphate beads) can be placed in the body 206. For example, a cap 205 can be removed (e.g., unscrewed) and the beads 201 can fall into the body 206. After loading the beads 201, the cap 205 can be replaced on the body 206. In other examples, the cap 205 can be secured to the body 206 by friction engagement. Other locking mechanisms are also possible.

[0077] Figure 7B The illustration shows a combination of cleaning equipment 220. Figure 7A The toilet tank of container 221 contains polyphosphates. Figure 6B The diagram illustrates a toilet tank 210 including a fill valve 421 and a flush valve 212. The fill valve 421 can be configured to control the volume or flow rate of water entering the tank 210. The fill valve 421 is in fluid communication with the polyphosphate container 221 via an inlet pipe 216 (polyphosphate container inlet conduit). The polyphosphate container 221 is connected to a cleaning device 220 via a pipe 217 (polyphosphate container outlet conduit). In other words, pipe 217 connects the outlet of the polyphosphate container 221 to the inlet of the cleaning device 220. In this way, dissolved substances from the polyphosphate container 221 are supplied to the cleaning device 220 along with water via pipe 217. The outlet of the cleaning device 220 is connected to the flush valve 212 via an outlet pipe 218 (cleaning device outlet conduit). In this way, dissolved substances from the polyphosphate container 221 and dissolved substances from the cleaning device 200 are mixed together and supplied to the flush valve 212 via pipe 218. Water containing the two dissolved substances is supplied to tank 210 and / or toilet bowl.

[0078] Specifically, pipe 217 can be connected to the inlet connector of cleaning device 220. Valve 421 can be configured to control the volume or flow rate of water supplied to cleaning device 220. In some examples, valve 421 may include a float device 521 for controlling the inlet valve, for example by opening the valve after an operating cycle to refill tank 210 and supply water to cleaning device 220, and closing the valve when the water in the tank reaches a preset volume or height. In some examples, filling valve 421 can be configured to supply a certain amount of water to cleaning device 220 (e.g., via first conduit 217) and to supply a certain amount of water directly to tank 210 or flush valve 212. Flushing valve 212 can be configured to control the flow of water and / or cleaning solution from tank 250 into toilet (e.g., base, rim channel, sump jet channel, toilet bowl, sump, drain channel, and the like), the cleaning solution being based on dissolved compounds from polyphosphate container 221 and / or dissolved compounds from cleaning device 220. In some embodiments, water containing dissolved chlorine and / or dissolved polyphosphate is supplied directly to the edge.

[0079] like Figure 7B As shown, pipe 217 is divided into two parts. The upstream part 217A connects container 221 to diverter 50 (e.g., a T-connector, a tee connector), and the downstream part 217B connects diverter 50 to cleaning device 220. Diverter 50 separates the water flow leaving container 221, including dissolved polyphosphates, so that this flow is used to fill the tank. Water drips from diverter 50 into the tank. In this way, chlorine or other cleaning agents from cleaning device 220 are prevented from being released into the tank, avoiding potential damage from certain chemicals in the tank (e.g., degradation of seals or rubber components). Water containing chlorine solution from cleaning device 220 is then supplied (e.g., via an overflow pipe) to other components in the toilet bowl, rim, sump, and / or toilet base. The diverter is sized to proportionally distribute the water supplied to the tank and cleaning device 220. More water can be supplied from diverter 50 to the tank than to the cleaning device 220.

[0080] In other words, all the water from the polyphosphate container 221 is diverted between the tank and the cleaning device 220, so that water containing the first dissolved compound is supplied to the toilet tank and the cleaning device. In the cleaning device, a second dissolved compound is added to the water supplied to the toilet bowl.

[0081] The flush valve 421 can be in fluid communication with the cleaning device 220 via a pipe 218. Specifically, the pipe 218 can be connected to the outlet connector of the cleaning device 220. For example, when the fill valve 421 is open, the cleaning device 220 can supply water and / or cleaning solution to the flush valve 212. The flush valve 212 can supply a volume of cleaning solution from the cleaning device 220 to the tank 250 and / or other parts of the toilet. Specifically, in some examples, the flush valve 212 supplies water and / or a cleaning solution based on a dissolved compound from the polyphosphate container 221 and / or a cleaning solution based on a dissolved compound from the cleaning device 220 directly to the tank 250.

[0082] Figure 8A Another embodiment of the polyphosphate container 22 is illustrated, which is configured to reduce limescale buildup in the toilet. Figure 8B The diagram includes Figure 8A 222 toilet tanks containing polyphosphates. Figure 8A and Figure 8B The operation of the device can be similar to Figure 7A and 7B The described operation.

[0083] Figure 8A Further illustration shows that the polyphosphate container 222 may include multiple rows of beads 201. In other words, the beads 201 may be arranged linearly in three-dimensional space. The body 206 includes beads 201 linearly arranged in the horizontal direction. The body 206 includes beads 201 linearly arranged in the vertical direction. The body 206 includes beads 201 linearly arranged in the depth direction.

[0084] Figure 8A Further illustration shows that the polyphosphate container 220 may include multiple coatings or materials for the body 206. For example... Figure 8A As shown, at least a portion of the polyphosphate container 222 includes a reflective coating 223. At least a portion of the polyphosphate container 200 includes a transparent, translucent, or light-transmitting material 224.

[0085] Figure 8BA diverter 50 (e.g., a T-connector, tee connector) is included between pipe 217 and polyphosphate container 222. Diverter 50 distributes the water flow leaving polyphosphate container 222, which contains dissolved polyphosphate, so that this flow is used to fill the tank. Water drips from diverter 50 into the tank. In this way, chlorine or other cleaning agents from polyphosphate container 222 are prevented from being released into the tank, as certain chemicals could potentially cause damage (e.g., degradation of seals or rubber components). Water containing chlorine solution from cleaning device 220 is then provided (e.g., via an overflow pipe) to other components in the toilet bowl, rim, sump, and / or toilet base. In some embodiments, water containing dissolved chlorine and / or dissolved polyphosphate is provided directly to the rim.

[0086] Figure 9A and 9B The illustration shows a dual-chamber water treatment device 230, in which a polyphosphate solution and a cleaning solution are dispensed by a single device. Figure 9A This is a top view of the dual-chamber water treatment equipment 230. Figure 9B This is a side view of a dual-chamber water treatment device 230. The water treatment device 230 includes a first chamber 232 and a second chamber 233 connected by at least one passage 231. The first chamber 232 and the second chamber 233 may be enclosed in a single housing. The first chamber 232 includes at least one input 235 and at least one output 234. The second chamber 233 includes at least one output 236. Additional, different, or fewer components may be included.

[0087] The first chamber 232 may include a polyphosphate solution and may be referred to as the polyphosphate chamber. The second chamber 233 may include hypochlorous acid (HOCl) or other weak acids or other chlorine-containing acidic solutions.

[0088] Water can be supplied to inlet 235 from a pipe or conduit connected to the filling valve. Alternatively, inlet 235 can be directly connected to a water supply device. Water can flow freely into the first chamber, and when the water level reaches channel 231, water containing at least some polyphosphate can flow into the second chamber 233.

[0089] Water can also flow from the first chamber 232 to the water tank via the outlet 234. In some examples, the outlet 234 is located at the top of the first chamber 232, allowing water containing polyphosphates to flow into the water tank through the outlet 234. In other examples, the outlet 234 may be located on the side or bottom of the first chamber 232.

[0090] The water in the second chamber 233 is mixed with hypochlorous acid. Therefore, at least some of the water in the second chamber 233 contains polyphosphates and is mixed with or otherwise diluted with hypochlorous acid. The water discharged through outlet 236 includes both hypochlorous acid and polyphosphates and is supplied to the toilet bowl through one or more channels (e.g., base, edge channel, sump jet channel, sump, drain channel, or others).

[0091] like Figure 9B As shown, the first chamber 232 may include a polyphosphate (e.g., beads 201 (e.g., TAC beads)) and may be referred to as the polyphosphate chamber. The second chamber 233 may include a hypochlorous acid tablet 601 or other solutes including chlorine. Other tablets that are soluble in water to form a weak acid may be used.

[0092] Water can be supplied to inlet 245 from a pipe or conduit connected to the filling valve. Alternatively, inlet 245 can be directly connected to a water supply device. Water can flow freely into the first chamber, and when the water level reaches channel 241, water including at least some dissolved polyphosphate can flow into the second chamber 243.

[0093] Water in the second chamber 243 is mixed with hypochlorous acid at water level 247. The height of water level 247 can affect the concentration of hypochlorous acid. Therefore, at least some of the water in the second chamber 243 includes dissolved polyphosphate compounds and is mixed with or otherwise combined with water and dissolved hypochlorous acid tablets. Water discharged through outlet 246 includes dissolved hypochlorous acid compounds and dissolved chlorine substances. Water including both dissolved compounds is supplied to the toilet bowl through one or more channels (e.g., base, edge channel, sump jet channel, sump, drain channel, or others).

[0094] Figure 11A and Figure 11B An example of a combined polyphosphate and cleaning compound water treatment device 260 is illustrated. The water treatment device 260 includes an inlet 251, an outlet 252, a suspension support 253, a concentration knob 254, a cover 255, and a reservoir 256. Additional, different, or fewer components may be included.

[0095] The housing includes a reservoir 256 configured to store a volume of polyphosphate, a cleaning compound, and water. As described above, the polyphosphate can be a tablet or a solution. The polyphosphate can begin as a tablet and then dissolve in a solution. Similarly, chlorine can be a tablet or a solution. Chlorine can begin as a tablet and then dissolve in a solution. Figure 10A As shown, the storage unit 256 can be a hollow or open space (e.g., a compartment) disposed within the housing. Figure 10AThe illustration shows a lid 255 selectively provided to an inlet to a reservoir 256. For example, when the lid 255 is in the upward or open position, a user can place one or more units of polyphosphate and / or cleaning compound into the reservoir. In some examples, the lid 255 may be transparent, allowing the user to view the amount of polyphosphate and cleaning compound contained in the reservoir 256 through the transparent lid 255. The lid 255 is at least one cap removable from the reservoir 256 to hold a first soluble compound and / or a second soluble compound.

[0096] The cleaning compound, polyphosphate compound, and a certain volume of water supplied to the reservoir 256 can be configured to mix or react with each other in the reservoir 256 to form or generate an anti-scaling solution. According to some examples, a certain volume of water can be supplied to the reservoir 256 through a fill valve located in the toilet tank. The anti-scaling solution can be supplied from the reservoir 256 or dispensed into the toilet bowl.

[0097] Inlet connector 251 and outlet connector 252 can be coupled to one of the second pair of sides (e.g., identical) of the water treatment device 260. Inlet connector 251 can communicate with a water source (e.g., the inlet valve of a toilet) and can be configured to direct or supply a flow or volume of water. Outlet connector 252 can be configured to supply or direct a flow of cleaning solution to the interior of the flush valve and / or toilet tank. A conduit (e.g., a hose, tube) can extend between outlet connector 252 and the interior of the flush valve and / or toilet tank. In some examples, the antiscaling solution can be supplied directly to the interior of the toilet tank. In other examples, the antiscaling solution can be supplied to the flush valve and subsequently from the flush valve to the interior of the tank. In some examples, the cleaning solution can be supplied (e.g., via a conduit, flush valve) to the toilet rim passage, sump jet passage, or commode without being introduced into the interior of the toilet tank.

[0098] The water treatment apparatus may further include a diffuser 257 in communication with a storage tank 256. The diffuser 257 may be configured to supply or deliver a quantity of water to the storage tank and a quantity of polyphosphate solution from the storage tank 256. Specifically, the diffuser 257 may include a tube with multiple openings communicating with the storage tank 256. In some examples, such as... Figure 10BAs shown, the tube can have a generally "U"-shaped shape. The tube can be configured to both deliver a quantity of water or a flow of water to reservoir 256 and a quantity of cleaning solution or a flow of cleaning solution from reservoir 256. Specifically, tube 501 can introduce a quantity of water into reservoir 256. In some examples, the water introduced into reservoir 256 can be mixed with a cleaning compound, dissolving the cleaning compound (e.g., a portion of the cleaning compound) to form a cleaning solution. In some examples, in addition to mixing with the cleaning compound, the water introduced into the reservoir can also be mixed with a quantity of the cleaning solution (i.e., the portion of water previously introduced into the reservoir and mixed with the cleaning compound).

[0099] refer to Figure 10B In some examples, the water treatment device 260 may also include a dial 254. In some examples, the dial 254 may be configured to control the concentration of the polyphosphate solution in the reservoir 256 (e.g., by rotating the dial between two or more settings). For example, the dial 254 may control the degree and / or duration of opening or closing of one or more valves supplying water to the reservoir, thereby controlling the amount of water supplied to the reservoir 256 and the concentration of the cleaning solution. In other examples, the dial 254 may be configured to change the volume or amount of cleaning solution dispensed by the water treatment device 260 (e.g., by rotating the dial 254 between two or more settings).

[0100] The water treatment device 260 may further include a hanger 253. The hanger 253 can be used to attach the device 250 to the side or wall of a toilet tank. Specifically, the hanger 253 may have a hook-shaped design.

[0101] Figure 11A and Figure 11B Another example of a water treatment device 260 is illustrated, which includes a first housing and a second housing. The first housing has a polyphosphate container or chamber 258, and the second housing has a chlorine chamber 259. The water treatment device 260 includes an inlet 261, an outlet 262, a suspension support 263, a concentration knob 254, and a cover 255. The chlorine chamber 259, included in the second housing, can be supported by a toilet tank via the suspension support 263. The polyphosphate chamber 258, included in the first housing, can be supported by the chlorine chamber 258.

[0102] like Figure 11BAs shown, the inlet 265 of the second housing connects the chlorine chamber 259 to the polyphosphate chamber 258, allowing water containing dissolved polyphosphate to flow from the polyphosphate chamber 258 to the chlorine chamber 259. Furthermore, the outlet 266 of the second housing connects the chlorine chamber 259 to the polyphosphate chamber 258, allowing water containing both dissolved chlorine and dissolved polyphosphate to flow from the chlorine chamber 259 to the polyphosphate chamber 258. Finally, the water containing both dissolved chlorine and dissolved polyphosphate flows out of the water treatment device 260 via the outlet 262. Additional, different, or fewer components may be included.

[0103] exist Figure 11A and Figure 11B In one embodiment, diffuser 257 and dial 254 may be included in chlorination chamber 259 to deliver a quantity of water to chamber 259 and to provide or deliver a quantity of solution from chamber 259. Specifically, diffuser 257 may include a tube having multiple openings communicating with reservoir 256. In other examples, polyphosphate chamber 258 and chlorination chamber 259 may each include a separate diffuser 257 and a corresponding dial 254.

[0104] Inlet 261 is at least one first chamber opening for water to enter the first chamber 258. Outlet 262 is at least one first chamber opening for water and the first dissolved compound to exit the first chamber 258. Inlet 265 is at least one second chamber opening for water and the first dissolved compound to enter the second chamber 259. Outlet 256 is at least one second chamber opening for water, the first dissolved compound, and the second dissolved compound to exit the second chamber 259.

[0105] Figure 11A The system includes a vacuum breaker 269 configured to prevent any backflow of substances from the dissolved chlorine compound from the second chamber 259 to the polyphosphate chamber 258 and / or the water tank. The vacuum breaker 269 may include a plastic disc that is pressed forward from the first chamber 259 into the second chamber 259 by water supply pressure. When the pressure decreases, the disc has a spring-loaded action that blocks the opening for water flow, thereby preventing any backflow.

[0106] Figure 12A and Figure 12BAnother example of a water treatment apparatus 270 with a reservoir 256 is illustrated. The reservoir 256 may be divided by a wall 274 into a first chamber 275 and a second chamber 276. The first chamber 275 may be connected to a fill valve and configured to contain a dissolved compound (e.g., polycarbonate beads 201). The second chamber 276 may be connected to a flush valve and configured to contain a second dissolved compound (e.g., chlorine tablets 601). The wall 274, together with the housing of the water treatment apparatus 270, may form at least one channel 277 for fluid connection between the first chamber 275 and the second chamber 276.

[0107] The inlet 271 for entering the first chamber 275 is at least one first chamber opening for water to enter the first chamber 275. The outlet 272 is at least one first chamber opening for water and the first dissolved compound to leave the first chamber.

[0108] Figure 13 Another example of a polyphosphate container 400 and water treatment equipment is illustrated. The polyphosphate container 400 includes multiple columns 401. Each column 401 includes one or more polyphosphate beads 201 or other soluble compounds. Water flows into the polyphosphate container 400 from a supply inlet 403 and into a distribution pipe 405. The water flows into the multiple columns 401 and dissolves the polyphosphate beads 201 or other soluble compounds. Figure 13 In the middle, the distributor pipe 405 may narrow from right to left (e.g., the inner diameter of the distributor pipe 405 may decrease at a distance away from the water supply inlet 403). After multiple columns 401, the collection pipe 402 collects water and dissolved compounds and provides the mixture to the outlet 405. Additional, different, or fewer components may be included.

[0109] Figure 14An exemplary columnar polyphosphate container water treatment device 410 is illustrated. Any columnar arrangement described herein can also be implemented as a horizontal embodiment, wherein the width of the device 410 is greater than its height (e.g., arranged in horizontal rows). Any number of horizontal rows or vertical columns can be used. At least one input 403 receives a supply of water distributed by a diffuser 407 into a plurality of water columns 401 within a housing 412. The water columns 401 may be separated by walls extending vertically within the polyphosphate container. Alternatively, the water columns 401 may be defined according to a cylindrical structure (e.g., a vertical chamber having a circular cross-section and formed of plastic or resin). Each of the water columns 401 comprises polyphosphate beads 101 or other soluble compounds. The diffuser 407 may distribute the water flow rate. The diffuser 407 may slow the water flow, which increases the static pressure. The diffuser 407 may equalize (e.g., substantially equalize) the water flowing within the plurality of columns 401. A collection conduit 402 receives the water from the water columns 401 and the dissolved compounds. Collection pipe 402 connects to return vertical pipe 406, which supplies water and the dissolved compound to outlet 404. As described herein, the outlet supplies water to a toilet tank, flush valve reservoir, or toilet bowl.

[0110] The columnar polyphosphate container water treatment unit 410 may include an indicator 409 to alert the user when the polyphosphate is depleted. A controller may provide commands to the indicator 409. The controller may be powered by a battery, a power outlet, or a hydrogenator. The indicator 409 may include a light for visual alarms, a speaker for audible alarms, or a transmitter for electronic alarms to another device. The soluble substance may be consumed within a predetermined time or number of flushes. The columnar polyphosphate container water treatment unit 410 may detect the level of remaining substance or track the time period to provide an alert to the user.

[0111] In one example, the columnar polyphosphate container water treatment device 410 may include a sensor for detecting the concentration of dissolved substances in the water. The sensor provides data to a controller, which compares the concentration to a threshold and triggers an indicator 409 when the concentration falls below the threshold.

[0112] In one example, the columnar polyphosphate container water treatment device 410 can count the number of flushes. The controller can count flushes based on the actuation of flushes or electronically (e.g., solenoid-powered) flushes.

[0113] In one example, the columnar polyphosphate container water treatment device 410 can trigger indicator 409 based on time. For example, the controller may include a timer that indicates when a predetermined time has elapsed. The predetermined time could be one year. After one year, the controller triggers indicator 409 to instruct the user to replace the polyphosphate beads 201.

[0114] In another example, the polyphosphate beads 201 may be combined with a dye that serves as an indicator of the lifespan of the polyphosphate beads 201. For example, the beads may include a colored dye (e.g., green) so that when green water is present in the toilet bowl, the user is confident that the polyphosphate beads 201 are still present in the treatment device 410. In another example, the center of the beads may include a colored dye (e.g., red) so that when the polyphosphate beads 201 have dissolved to the vicinity of the center, the toilet water turns red, alerting the user that the polyphosphate beads 201 should be replaced or otherwise added to the treatment device 410. These dye examples can be applied to any of the embodiments described herein.

[0115] Figure 15 The illustration shows the inlet placement of a columnar polyphosphate container water treatment device 410, which is part of an exemplary water treatment device 500. Figure 15 Examples include two columns in a columnar polyphosphate container water treatment device 410. The columnar polyphosphate container water treatment device 410 is connected to a fill valve 411 of a toilet tank by multiple fluid conduits.

[0116] The fill valve assembly includes a water supply device 422 (e.g., a conduit, pipe, connector), a float 420, and a fill valve 421. As water enters the tank from the utility via the water supply device 422, a side connector 423 diverts the water flow from the fill valve assembly and through a fill bypass pipe 418 to the cylindrical polyphosphate container water treatment unit 410. The fill bypass pipe 418 is removably connected to the cylindrical polyphosphate container water treatment unit 410 using a connector 424. The connector 424 can be a threaded connector or a cap that connects the bypass pipe 418 to the cylindrical polyphosphate container water treatment unit 410.

[0117] Another water inlet can be supplied to the columnar polyphosphate container water treatment unit 410 via pipe 417 from the overflow outlet of the filling valve assembly. When the water level in the tank is low, for example after flushing, the float 421 descends and opens the filling valve 421 at the top of the filling valve assembly. At this time, the water flow is not supplied down the overflow pipe to fill the sump of the toilet bowl, but is first diverted to pipe 417 and enters the columnar polyphosphate container water treatment unit 410.

[0118] Within a columnar polyphosphate container water treatment device 410, one or more polyphosphate beads 201 or other soluble solids are disposed in a housing 412 to dissolve in water.

[0119] The columnar polyphosphate container water treatment device 410 may also have two outputs. A first output 413 may be provided by a pipe connected to the cleaning device 220. Alternatively, the first output 413 may be connected to the upper rear portion of the overflow section of the filling valve assembly. The second output 425 may be an opening, nozzle, or pipe that supplies water containing the dissolved compounds back to the water tank.

[0120] In this example, pipe 418 is a first pipe connecting the first output of the fill valve to the container, and pipe 417 is a second pipe connecting the second output of the fill valve to the container. Furthermore, output 413 can be connected to a third pipe that connects the first output of container 410 to the fill valve assembly. Finally, a fourth pipe can connect output 425 of container 410 to the toilet tank.

[0121] Figure 16A An exemplary toilet with an internal columnar water treatment device is illustrated. In this example, a columnar polyphosphate container water treatment device 410 is connected inside the toilet 430. The toilet 430 can be a tankless toilet or a smart toilet. Water is supplied from a utility or other water source to the columnar polyphosphate container water treatment device 410 and then flows out to the rim, sump, or other jet of the toilet 430.

[0122] Figure 16B An exemplary toilet with an external columnar water treatment device is illustrated. In this example, the columnar polyphosphate container water treatment device 410 is mounted to a wall or other structure outside the toilet 440. Water is supplied from a utility or other water source to the columnar polyphosphate container water treatment device 410 and then flows out to the rim, sump, or other jet of the toilet 440.

[0123] Figure 17A Another exemplary external water treatment device 441 for toilet 450 is illustrated. Figure 17B The illustration shows a water treatment device 441 that may include a housing 444 comprising a plurality of polyphosphate beads 201 or other soluble compounds. The housing 444 may include a plurality of chambers as described herein. The housing 444 may be removable. The housing 444 may be clipped into an upper mounting member 445, which includes a rotating cap 446.

[0124] like Figure 17C As shown, a water supply hose can be connected to the water treatment device 441 at connector 443. A manual valve 442 can be configured to prevent water from flowing from the water supply device at connector 443 into the housing 444.

[0125] When the user loads new polyphosphate beads 201 or other soluble solids into the housing 444, the user can turn the manual valve 442 to shut off the water supply. The housing 444 can then be rotated using the rotating cap 446 to expose the opening for loading the polyphosphate beads 201. Finally, the loaded housing is reattached to the upper mounting 445, and the manual valve 442 is returned to the open position.

[0126] Figure 18 The illustration shows another external cylindrical polyphosphate container water treatment device 410 for toilet 280. Accessories (e.g., toilet brush 271) can also be cleaned using the cylindrical polyphosphate container water treatment device 410. In this example, polyphosphates or other soluble solids can dissolve in a cavity substantially sealed by the toilet brush. For example, the brush base 372 can provide a cap or cover for the cavity. The accessories are then cleaned using the same water supplied to toilet 280.

[0127] Figure 19 An exemplary controller for any anti-scaling system using electricity (e.g., indicator 409) and / or an electronic flushing valve is illustrated. Controller 400 may include processor 300, memory 352, and communication interface 353 for interacting with the device or the Internet and / or other networks 346. In addition to communication interface 353, a sensor interface may be configured to receive data from sensors described herein or from any source for detecting the presence of water, the presence or intensity of disinfectant, actuation of flushing cycles, or the presence of a user or gesture. Components of control system 400 may communicate using bus 348. Control system 400 may be connected to a workstation or other external device (such as a control panel) and / or a database to receive user input, system characteristics, and any values ​​described herein.

[0128] Figure 20 The diagram illustrates a flowchart of the operation of a water treatment apparatus that includes an anti-scaling chamber and a cleaning chamber. Additional, different, or fewer actions may be included.

[0129] In action S101, controller 400 sets a timer. The timer can be a preset timer with an unchanging duration. The timer duration can be set by a user (e.g., from input device 355). The timer duration can be accessed from memory 352. The timer duration can be set by a toggle switch. The timer duration can be associated with a specific type of soluble compound placed in the water treatment equipment. In some cases, the anti-scaling chamber and the cleaning chamber can use separate durations. In this example, controller 400 can select the shorter of the two durations. In action S103, controller 400 determines when the timer reaches its duration.
