[0004] The present application generally relates to disinfecting systems for use in bathrooms (eg, toilets, fans, hair dryers, or other appliances). Background Art

[0005] Generally speaking, aerosols consist of very small particles or droplets suspended in the air. These aerosols are particularly prevalent in enclosed spaces, and more prevalent in enclosed spaces where water is used. For example, in a bathroom, aerosols may be emitted from several places, the most important of which is the toilet.

[0006] Aerosols can be removed from the air that humans breathe through the human respiratory system. However, some aerosols may be toxic and may even bring viruses into the human body. The problem of aerosols can be alleviated by disinfecting the air. In addition, in use, scale (e.g., urine scale), minerals, bacteria and other unwelcome deposits (e.g., biofilms) accumulate on the surface of the toilet, particularly on the inner surface of the toilet bowl. In addition, these deposits may become trapped in small flaws in the inner surface of the toilet that may be a glassy material. These accumulated deposits can cause unpleasant odors and stains, and breed germs and bacteria. It would be advantageous to provide the following toilet: the toilet has an internal cleaning system that provides improved cleaning to solve the aforementioned problems. Summary of the invention

[0070] The following embodiments include systems, devices and methods for disinfecting and / or sterilizing one or more surfaces and / or one or more spaces. These cleaning technologies can be applied to toilets or other devices found in bathrooms. For example, the following embodiments can be applied to sinks, sinks, showers, bathtubs, or bidets (e.g., floor-standing bidets). With respect to toilets, two specific areas targeted include the management of plumes and the disinfection of surfaces of the toilet or at least surfaces that are contacted by the human body. A plume is a cloud of tiny particles or droplets that are dispersed into the air as a result of flushing the toilet. The plume may include bacteria, germs, or fecal matter. Everyone who uses the toilet comes into contact with the seat or lid. Not only is that person likely to spread germs to these surfaces, but there is also the risk of spreading germs to others.

[0071] The plume may include particles of various sizes. The size of the particles in the plume may affect the potential distance traveled when expelled by the toilet. In addition, the size of the particles may affect how quickly the particles settle on a surface after being expelled. For example, a particle with a diameter of 100 microns may settle in seconds, while a particle with a diameter of 1 micron or less may remain in the air for hours. Viruses and bacteria may be 1 micron or less in diameter. Particles that remain in the air longer are more likely to be absorbed by the body. Particles that remain in the air longer are more likely to remain in the air after one user of the bathroom leaves and another enters.

[0072] Figure 1A An exemplary embodiment of a toilet 100 is illustrated, which includes a toilet bowl 101 (e.g., a base, a pedestal, etc.), a toilet seat assembly 102 coupled to an upper surface of the toilet bowl 101 (e.g., a platform, a ledge, etc.), and a water tank 103 for supplying water to the toilet bowl 101. It should be noted that the toilet seat assembly 102 and the embodiments disclosed herein can be used with any type of toilet (e.g., a one-piece toilet, a two-piece toilet, a skirt toilet, a smart toilet, etc.), and Figure 1AThe toilet 100 shown is an example implementation. In addition, the toilet 100 can be used with any type of toilet seat assembly and / or toilet attachment assembly (e.g., bidet assembly, heated seat, smart device, etc.). Figure 1A As shown, the toilet seat assembly 102 includes a seat 121 configured to support a person, a cover 122 (e.g., a cover, etc.) covering the seat 121, and a hinge 123 that rotatably couples the seat 121 and the cover 122 to the toilet 100 (e.g., an upper surface). A portion of the hinge 123 can be mounted to the upper surface to fix the portion of the hinge 123 in place relative to the bowl 101 to allow the seat 121 and the cover 122 to rotate independently relative to the portion and the bowl 101. In addition, as discussed in more detail herein, the hinge 123 can also fix a plume cleaning system to the toilet 100, and the plume cleaning system can utilize various disinfection, sterilization, or other cleaning techniques to clean the plume of the toilet 100. In addition or alternatively, the plume cleaning system can be coupled to the cover 122 or the seat 121. The plume is a dispersion of tiny particles or aerosols from the toilet 100. The plume can be forced out of the toilet bowl 101 as a result of a normal flush cycle. That is, adding water (e.g., a stream of water) to the bowl can cause a flow of air - called a plume - to go up and out of the bowl 101.

[0073] Figure 1B and Figure 1C The hinge is illustrated as including a water tank for storing a disinfectant, sanitizer, or other solution. The water tank includes an opening 106 configured to receive a disinfectant into the water tank 108. The disinfectant may be hydrogen peroxide (H2O2). Hydrogen peroxide is antiviral and antibacterial. Hydrogen peroxide is an example antibacterial agent because it can kill bacterial cells by destroying cell walls. Hydrogen peroxide is also more effective than chlorine bleach in reaching and killing mold on porous surfaces. To be used as a disinfectant, hydrogen peroxide may be applied to the surface and simply air dried. Other solutions that may be stored in the water tank 108 may include quaternary ammonium, tetraacetylethylenediamine, phenolic acid, isopropyl alcohol, sodium carbonate, peroxyhydrate; tetraacetylethylenediamine, ethanol, sodium hypochlorite, octanoic acid, or sodium chlorite. The solution stored in the water tank may be selected from or include one or more ingredients selected from the "List N of Disinfectants maintained by the Centers for Disease Control" and available at https: / / cfpub.epa.gov / giwiz / disinfectants / index.cfm.

[0074] As an alternative to these chemical solutions, the water tank 108 can include electrolyzed water. The electrolyzed water can be referred to as electrolytically oxidized water, electro-activated water, or electrochemically activated aqueous solution. The electrolyzed water can be produced by electrolyzing water (e.g., ordinary water or tap water) dissolved with sodium chloride. The electrolysis can produce hypochlorous acid and sodium hydroxide. The electrolysis can include applying a direct current (DC) power source that is coupled to a plurality of electrode plates composed of a conductive material such as a metal.

[0075] Connected to the tank 108 or one or more other locations of the toilet 100 is a misting distribution system that provides disinfectant to the bowl 101. The distribution system may generate a mist or cloud 109. The mist may be operated as a gas that expands in space to reach substantially every surface within the bowl 101. An example distribution system may be incorporated into the toilet seat assembly 102. The distribution system may include a filling and control portion 105. As shown in FIG. Figure 1C The well-illustrated filling and control portion 105 may include a filling opening 106 that is opened or closed by a filling cover 107. As discussed in more detail below, the user input 10 may include a button, switch, or keyboard for controlling the operation of the dispensing system. The user input 10 may turn the dispensing system on or off. The user input 10 may cause the dispensing system to generate a mist or cloud 109. In addition or alternatively, the sensor 11 may detect one or more characteristics of the surrounding environment or the toilet. The sensor 11 may detect the presence of aerosols or particles near the toilet 100. The sensor 11 may detect the operation of the toilet 100 (e.g., a flush cycle). The controller 12 may receive sensor data collected by the sensor 11, analyze the sensor data, and control the dispensing system in response to the analysis.

[0076] Figure 1D An example electrolytic water reactor 60 for a disinfection system is illustrated. The electrolytic water reactor 60 can perform electrolysis within a water tank 108 via a cathode 61 and an anode 62. The water tank 108 can include a separate housing that defines the reactor 60 and includes an anode compartment for the anode 62 and a cathode compartment for the cathode 61, which can be separated by a porous partition 63. In the anode compartment, a cleaning solution (alkaline) is produced, while in the cathode compartment, a disinfecting solution (acidic) is produced.

[0077] As a more specific example, at the cathode 61, hydrogen gas and hydroxide ions can be produced. At the anode 62, chloride ions can be oxidized to elemental chlorine. Near the cathode 61, the resulting alkaline solution is corrosive, while near the anode 62, the solution includes sodium hydroxide. When hypochlorous acid without elemental chlorine is formed near neutral pH, a disinfectant can be produced. A neutralizer (e.g., vinegar) can be added to achieve a target pH range.

[0078] The controller turns the current on and off to the cathode 61 and / or anode 62. The controller can provide a charge or bias to the cathode 61 to generate a current between the cathode 61 and the anode 62. The controller can operate a valve to add a neutralizer from the neutralizer compartment to the reactor 60. A disinfecting solution can be an example antiseptic provided to the bowl 101.

[0079] Thus, in this example, the biocide can be generated at the toilet 100 (e.g., within the tank 108), or the biocide can be added to the tank 108 by refilling from a bottle or other container at the fill and control portion 105. User refilling through the fill and control portion 105 simplifies the required equipment but requires more intervention. Generating the biocide (electrolyzed water) within the tank 108 requires a more complex structure including the reactor 60, but requires less user intervention.

[0080] Figure 1E An example atomizing distribution system including a mist or fog generator 93 is illustrated. The atomizing distribution system may also include an electrostatic collection device 91 and a fan 92. The fog generator 93 may include an ultrasonic atomizer or transducer that converts high-frequency sound waves into mechanical energy, which is converted into standing waves of the disinfecting fluid, thereby causing the mist or fog to be ejected. The fog generator 93 may be connected to a water tank 108 to draw liquid and generate mist or fog. The water tank 108 may be connected using a pump or a capillary tube.

[0081] The electrostatic collection device 91 may include a collector inlet path and a collector outlet path. The electrostatic collection device 91 may be formed of plastic and include an electrostatic charge (e.g., a permanent electrostatic charge) on the surface of the plastic. The charge may be formed passively (e.g., by manufacturing or friction) or actively (e.g., by a power source). The electrostatic collection device 91 may include a plurality of fins having an electric charge. The fins may be radially arranged in a circle. Different fins may be positioned at different angles relative to a normal (e.g., a vertical line or gravity). Small particles of dust and biological particles tend to form an electric charge on the surface of the particles, even if the charge is weak. The electrostatic collection device 91 adsorbs and collects particles. Air may travel into the electrostatic collection device 91 through the collector inlet path, be exposed to the electrostatic charge, and travel out of the electrostatic collection device 91 through the outlet path.

[0082] The combined mist and toilet plume is drawn into the fan 92 through the fan's air inlet 94 (fan inlet) and is expelled by the fan 92 through the fan outlet. The combined mist and toilet plume circulates within the circulation chamber 95 and is provided to the electrostatic collection device 91. The plume of small particles is captured by the electrostatic collection device 91 by adsorbing the charge of the particles. As part of this recirculation path, the electrostatic collection device 91 provides purified air (i.e., the combined mist and toilet plume with a large number of particles removed) to the dense fog generator 93. The fog generator 93, which can provide an air flow from the fan 92, adds new fog particles to the clean air and provides the fog and air to the toilet bowl. Whether or not additional plume air is added (e.g., by flushing), the fog and air are recirculated through this path to eliminate pollutants or other particles from the air.

[0083] One or more batteries may be included to power the fan 92 and / or the mist generator 93. The batteries may be rechargeable. The toilet seat assembly may include a charging port (e.g., a universal serial bus or USB) for connecting the toilet seat assembly to a wall outlet or power line. In one example, the electrostatic collection device 91 also includes an electrostatic bar or plate powered by a battery or a wall outlet.

[0084] Additionally or alternatively, connected to the toilet seat assembly 102 or one or more other locations of the toilet 100 is a modular plume cleaning system. The modular plume cleaning system combines multiple disinfection, sterilization or cleaning technologies. The modular plume cleaning system may include modules that are interchangeable and connect and disconnect with the toilet seat assembly 102. The sensor 11 may detect the presence of a plume or one or more characteristics of the plume. The sensor 11 may detect the operation of the toilet 100 (e.g., a flush cycle). The controller 12 may receive sensor data collected by the sensor 11, analyze the sensor data, and control the dispensing system in response to the analysis.

[0085] Figure 2 A modular disinfection system for a toilet seat assembly 102 is illustrated. The toilet seat assembly 102 may include a fan 110, a modular docking piece 111, a control panel indicator or light 112, a control panel input 10, a vent 113, and a baffle 114. The rear of the toilet seat assembly 102 may house a water tank 108 for a cleaning solution or liquid. The water tank 108 includes a fill opening with a cover 107. Additionally or alternatively, the water tank 108 may be secured to the toilet seat assembly 102 and / or covered by a water tank cover 152 ( Figure 5 As shown in Figure 2 The control section, mounted on the rear housing as shown or elsewhere, may include a user input 10 and a light or indicator 112. Additional, different or fewer components may be included.

[0086] Figure 2 The modular disinfection system of the present invention includes an example plume cleaner assembly adjacent to a toilet seat cover 122 and a toilet seat 121 and independently removable relative to the toilet seat cover 122 and relative to the toilet seat 121. At least a portion of the plume cleaning assembly is located below the toilet seat 121. That is, as discussed in more detail below, the plume cleaning assembly extends below the top edge of the toilet seat 121.

[0087] The plume cleaner assembly includes at least one removable module. Various modules can be used with the toilet seat 121. Example illustrated modules include an impactor module 200, an electrostatic module 300, a hydroxyl module 400, and a multi-stage cyclone separator module 500. The module may include one or more openings or holes that provide a path for air to enter the plume cleaner assembly from the interior of the toilet bowl 101. The openings may have a longitudinal axis arranged at a particular angle. The angle may be substantially in the direction of gravity. The modules may each include a different example of a reactor trap. The reactor trap captures particles from the plume or from the mist discharged into the toilet bowl 101, or slows the travel of these particles so that they can be disinfected or otherwise cleaned, for example, by ultraviolet light.

[0088] The modules can be connected to the toilet seat 121 using a module docking piece 111. The modules can be connected to the toilet seat 121 and used to implement the modular disinfection system individually or in any combination. In some examples, the modules are stacked. The top module is connected to the module docking piece 111. Under the top module, another module is connected to the top module, and so on.

[0089] The module can have a variety of shapes. The shape can be substantially symmetrical with the shape of a toilet that is oval or teardrop-shaped. The shape can be any type of circular shape, such as having at least one cross-section that is oval or circular. Other shapes for the module can include square, rectangular, or circular. The module is shaped to mate with the cover 122 in a particular direction or orientation. That is, the module can be asymmetric. The module may include a partition 114 that aligns with a portion of the cover 122 and guides the fit between the toilet and the module. The partition 114 may refer to a frame for the module or a specific support member having a frame for aligning the module with the cover 122. The partition 114 may have a shape corresponding to the opening of the toilet seat 121. The partition supports the plume cleaner assembly.

[0090] The module docking piece 111 may include a snap-fit ​​connection with the module and / or the modules may form a snap-fit ​​connection with each other. The module docking piece 111 may include a recessed portion configured to cooperate with the protrusion on the top of the module. The protrusion of the module may include a hook or stud fitted in the recessed portion. The hook or stud may be pressed down (e.g., bent, offset) to align with the recessed portion, which fixes the connection and prevents the hook or stud from being easily removed from the recessed portion. In order for the modules to be stacked, the bottom of the module may also include such a recessed portion. Alternatives for the snap-fit ​​connection of the module docking piece 111 may include fasteners (e.g., screws or bolts), latches, clips or other hardware. The hardware for these connecting devices may be made of plastic or other rust-proof materials.

[0091] The toilet seat 102 is connected to the cover 122 via a hinge. The hinge includes a pin that fits through one or more joints of the toilet seat 121 and the cover 122 so that the toilet seat 121 can rotate relative to the cover 122. In one example, one or more of the modules includes at least one joint or other hollow circular portion through which the pin can pass. In this way, the module can be mounted to be independently connected to the cover 122 and the toilet seat 121 in a rotatable manner. In one example, the module is connected by both the hinge and the module docking piece 111.

[0092] The module docking piece 111 may also include an electrical connection or mechanical switch that indicates the identification of the module to the controller 12. That is, the controller 12 can receive information about the type of module that has been connected to the module docking piece 111. In one example, the module docking piece 111 may include a set of mechanical switches in a predetermined position. In another example, the module docking piece 111 may include a set of electrical contacts in a predetermined position. One switch or contact is located in a position aligned only with the impactor module 200, another switch or contact is aligned with the electrostatic module 300, another switch or contact is aligned with the hydroxyl module, and another switch or contact is aligned with the multi-stage cyclone separator module 500. When the module is installed, the controller 12 receives a signal in response to the switch or contact and selects one or more commands or algorithms in response to the connected module.

[0093] In addition, for the water tank 108, the rear housing may include at least one fan 110 and at least one corresponding vent 113. The fan 110 is positioned to draw plume air through the plurality of openings for treatment by the plume cleaner and to discharge the treated plume air out of the plume cleaner assembly in a direction angled to the longitudinal axis of the plurality of openings. The fan 110 may draw the plume air through a serpentine plume path between the toilet and the toilet seat cover or between the toilet and the toilet seat through the plume cleaner assembly. The serpentine plume path is configured to receive plume air from the toilet and direct the plume air through a plurality of turns. As discussed in more detail in other embodiments, the light source may be configured to illuminate the plume air of the serpentine plume path.

[0094] The module docking piece 111 is coupled to the toilet seat cover and is configured to removably attach one or more modules to the toilet seat cover. The modules may include any combination of the impactor module 200, the electrostatic module 300, the hydroxyl module 400, and the multi-stage cyclone separator module 500. The modules may be individually and interchangeably attached to the module docking piece 111. Two or more modules may be attached to the module docking piece (e.g., in another shape not shown) or two or more modules may be stacked.

[0095] Each of the modules may include a plurality of channels for air paths. The module may include at least one radial channel configured to direct plume air from the toilet bowl to an opening on an inlet into an output channel configured to direct the treated plume air to the fan 110.

[0096] Each of the modules may include a light source or be positioned proximate to a light source mounted on cover 122. Thus, the plume cleaner assembly is positioned adjacent to cover 122 and may include a cavity configured to receive a light source mounted to cover 122. The plume cleaner assembly adjacent to the toilet seat cover includes a transparent portion to provide a light path from the light source to the at least one radial channel.

[0097] Figure 3A and Figure 3B An air flow path through a disinfection system including a module 130 or a combination of modules is illustrated. The module 130 shown includes a catalyst reactor adjacent to the air flow path. The air flow path can draw air from multiple locations from the toilet bowl 101. Some of the air can travel into the toilet bowl 101 from internal passages of the toilet 100, such as the rim passages between the toilet bowl 101 and the water tank 103. Some of the air can travel from the environment of the toilet. The air flow path passes through the toilet bowl 101 and passes through the plume cleaning assembly via a network of openings 13. The fan 110 draws air from the openings 13 toward the vent 113.

[0098] Figure 3B A negative pressure area is shown that is created around the toilet seat 121 and / or between the cover 122 and the toilet seat 121. The negative air pressure indicates air flow from the outside of the toilet bowl 101 to the inside of the toilet bowl 101. The negative air pressure is maintained by the fan 110 drawing air out of the toilet bowl 101 toward the vent 113.

[0099] The air flow around the toilet seat 121 may include an upper path and a lower path. The air flow may extend from the outside of the toilet bowl 101 through the opening 133 to the upper path at the atomization chamber 134 above the toilet seat 121, and extend to the inside of the toilet bowl 101 at the low pressure area 139 through the opening 135. The air flow may extend from the outside of the toilet bowl 101 through the opening 133 and then extend to the bottom of the toilet seat 121, as shown by arrow 138.

[0100] Thus, even if the toilet plume is on a trajectory that would normally escape toilet 101 and / or deposit particles on toilet seat 102 (e.g., as shown by arrow 137), the negative air pressure prevents that trajectory from escaping bowl 101 or reaching any surface that a user might come into contact with.

[0101] The cover 122 can define several compartments or spaces that are partially closed or substantially closed. The cover 122 can include a module space 14 for a module. The module space 14 can extend below at least a portion of the toilet seat 102. For example, the module space 14 extends below the top of the toilet seat 102 near the opening 135. The cover 122 can include a closed space for the atomization system, a fluid distribution system chamber 136, which is discussed in more detail herein. The cover 122 can include a partially closed seat space or atomization chamber 134. Maintain pressure in the atomization chamber 134 so that air flows from the outside of the toilet bowl 101 to the inside of the toilet bowl 101. The air flow may be very close to zero. In other words, the pressure in the atomization chamber 134 prevents air from flowing out of the toilet bowl 101 in reverse.

[0102] The chambers may be defined based on the relative positions of the toilet seat 121 and the bowl 101. The space between the bowl 101 and the toilet seat 121 where the module or plume cleaning assembly is located when the toilet seat 121 is in the lowered position is a plume cleaning space including a plurality of chambers. The cover 122 may also define a fluid distribution system chamber 136 and an atomization chamber 134, and the toilet seat 121 at least partially encloses the atomization chamber 134 in the lowered position. The module space 14 may also be a plume cleaning chamber aligned with the bowl and filled with mist from at least one atomizer, the atomizer being configured to generate a negative relative air pressure in the atomization chamber, wherein the negative relative air pressure prevents air flow from the plume cleaning chamber or the surrounding environment from entering the atomization chamber.

[0103] Figure 4A and Figure 4B The liquid path through the disinfection system is shown. The path can start from the water tank 108 and extend to the plurality of atomizers 131 through the supply line 132. The supply line 132 can extend through the space 136. The supply line 132 can be supported by one or more brackets in the space 136. The pump 149 ( Figure 5 ) can pump liquid from the water tank 108 through the supply line 132. The pump 149 can be electric, with one or more moving parts driven by a motor. The moving parts can be impellers, pistons and diaphragms, blades or other components.

[0104] The compartments of the lid help manage the air flow over the seat surfaces, isolating them so that the maximum concentration of chemicals is obtained. The air flow helps to keep the chemicals inside the lid, helping to dry the surface while directing the mist into the bowl.

[0105] The particles of the plume are of various sizes, and the above modules can be designed to control the flow and disinfection of these particles. However, the atomizer 131 allows the plume to be controlled so that the particles leaving the plume adhere to the mist. The mist can be controlled. The mist can be controlled in terms of time, volume and size.

[0106] With respect to particle size, the atomizer 131 can be configured to generate mist particles of a specific size (e.g., less than 40 microns, or between 10 and 20 microns). The mist can be a thick dry mist that does not wet the surface of the toilet or make the surface feel damp or wet. Smaller particles tend to repel each other due to the weak static charge on the surface. Instead, smaller particles may coalesce into larger droplets and remain suspended in the air.

[0107] Examples of the atomizer 131 may include Figure 4B The atomizer shown in FIG. 131 includes a trumpet-shaped portion 141, an atomizer body 142, and a piezoelectric element 143. The atomizer body 142 is configured to receive a liquid flow and meter the liquid flow.

[0108] The liquid flow can be received locally from a water tank 108, which serves as a solution reservoir configured to deliver the solution to at least one sprayer. The trumpet 141 is configured to receive the metered liquid from the trumpet and the predetermined vibration to generate a standing wave, which causes the metered liquid to be atomized and leave the trumpet. The trumpet 141 can cause cavitation inside each droplet of the metered liquid. The piezoelectric element 143 or crystal is configured to convert the electrical signal into the predetermined vibration.

[0109] The ultrasonic horn may include a tip having a tip shape that determines the spray. The tip may be shaped to provide a 180 degree spray in one example and a 45 degree spray in another example. The tip may be configurable. The spray may be selected based on the location of a particular atomizer, the model of toilet, or user selection.

[0110] The trumpet 141 can be oriented differently to produce different spray patterns. Depending on how the interior of the trumpet 141 is coated with the metered liquid, different patterns can be produced in the mist.

[0111] In addition, the trumpet 141 can be oriented downward in a manner that effectively uses metered liquid. For example, the solution in the water tank 108 may be in limited supply, or at least the solution may be desired to last for a long period of time. In order to reduce the amount of solution used, a single droplet can be provided to the trumpet 141 by a pump. The droplet is held away from the surface of the trumpet 141 by surface tension, causing cavitation to occur. The trumpet 141 generates mist from the single droplet until the droplet is exhausted.

[0112] Another example of the nebulizer 131 may include an interdigital transducer configured to generate surface acoustic waves that atomize the liquid and leave the nebulizer. The power circuit is configured to provide a radio frequency signal to the surface acoustic wave, and the drive circuit is configured to control the actuator to meter the liquid flow into the nebulizer.

[0113] Another example of the atomizer 131 may include an atomizer wand configured to provide mist in a configurable predetermined direction.

[0114] The controller 12 is configured to control the atomizer 131. A programmable logic controller (PLC) may set a driving interval and a driving frequency of the piezoelectric element 143. The PLC may also set a maximum voltage or a maximum power supplied to the piezoelectric element 143.

[0115] As an initial example that can be combined with any of these examples, the controller 12 can include a timer. The disinfection system can be activated at specific time intervals (e.g., once an hour, once every four hours, or once a day). The user can select the specific time interval.

[0116] Any or all parts of the disinfection system - including the atomizer 131, the fan 110 and / or any modules - can be enabled or disabled by the controller 12 based on the operation of the toilet. The sensor 11 can detect whether the toilet seat assembly 102 is open or closed. The sensor 11 can detect the operation of the toilet. The sensor 11 can detect environmental conditions.

[0117] The sensor 11 may detect whether the toilet seat assembly 102 is open or closed using an optical sensor that detects whether the module is facing the interior of the toilet bowl 101 or facing the water. The sensor 11 may detect whether the toilet seat assembly 102 is open or closed using a tilt sensor or an inertial sensor. The sensor 11 may detect whether the toilet seat assembly 102 is open or closed using a mechanical switch that is depressed when the toilet seat assembly 102 is lowered. Magnetic, gravity, or other types of sensors may be used. The controller 12 may prevent the disinfection system from being activated when the toilet seat assembly 102 is raised or otherwise triggering the disinfection system when the toilet seat assembly has been lowered.

[0118] The controller 12 can select a cleaning sequence based on data from the sensor 11. For example, a weight sensor in the seat can be provided based on the user or type of use. A deep clean can be provided after some uses, while a quick clean can be provided after other uses.

[0119] Figure 5 Shows FIG. 3A to FIG. 3B and FIG. 4A to FIG. 4B Exploded view of the disinfection system in the toilet bowl, the disinfection system includes air flow and atomization for the toilet seat as previously described. Additional components may include one or more cam locks 153 for securing the toilet seat and disinfection system to the toilet.

[0120] Fig. 6A and 6B An example impactor module for a sterilization system is illustrated. Fig. 7A and Figure 7B An example impactor module 200 for a disinfection system is illustrated. The impactor module 200 may include an impactor plate 151 and an aperture 13. Additional, different, or fewer components may be included.

[0121] When the air is directed through the opening 13, the air is accelerated. The air can be accelerated because the volume of the air space in the opening 13 is lower than the volume of the air space before the opening 13. The accelerated air collides with the impactor plate 151. The collision causes any (e.g., most) suspended particles (e.g., aerosols, viruses, bacteria, or pollutants) to be deposited on the impactor plate 151. The light source 144 illuminates the impactor plate 151 and sterilizes or eliminates the deposited particles.

[0122] The impactor plate 151 blocks or slows down particles in the toilet plume, causing the particles to spend more time in the illumination light of the light source 144. Another technique for increasing the time spent in the illumination light of the light source 144 is a serpentine path for the air flow.

[0123] The serpentine plume path may be defined as a path that changes direction at least twice. The serpentine path does not take a short path between two points but increases the path so as to increase the time that the particles are in the illumination light of the light source 144. The plume assembly between the toilet 100 and the toilet seat cover 122 or between the toilet 100 and the toilet seat 121 includes a serpentine plume path to receive plume air from the toilet and guide the plume air through multiple turns.

[0124] An example serpentine path extends through a vertical passage toward the impactor plate 151, as shown by arrow A. Impact with the impactor plate 151 then causes the air flow to turn and move radially (in the horizontal direction), as shown by arrow B. The path then travels around the impactor plate 151 as the air is drawn in by the fan 110. Finally, the serpentine path extends to the vent, as shown by arrow D. The serpentine plume path includes a first portion in a first direction (e.g., arrow B) and a second portion in a second direction (e.g., arrow C). The first portion and the second portion share a wall (e.g., impactor plate 151).

[0125] Fig. 8A , Figure 8B , Fig.9A and Fig. 9B Another example impactor 220 for a disinfection system is illustrated. In one example, the impactor 220 may include a plurality of disks 210 (e.g., Figure 8B A stack of disks 210a, 210b, and 210c is illustrated.) In some examples, the impactor 220 includes a light source and in other examples the light source is omitted.

[0126] Each disk may include a plurality of channels or openings. The air stream may flow through one of the disks and then be forced through a horizontal path to the channels of the next disk. In this way, a series of disks form a serpentine path. The air may be forced vertically through one disk and then horizontally between the disks.

[0127] The impactor 220 may include a divider 212 within or between the disks that divides the space within the impactor 220 into chambers 211. The chambers 211 may have a variety of shapes. The divider 212 divides the air path so that air flowing upward through the disk is forced into another direction. The serpentine plume path includes a first path portion that is a generally vertical path toward a horizontal obstacle provided by the disk 210 and a second path portion that is generally horizontal and parallel to a horizontal obstacle provided by a vertical obstacle such as the divider 212.

[0128] The partition 212 may have a space in the radial direction to allow air to flow between the chambers 211. Therefore, the serpentine plume path may include a third path portion around the horizontal obstacle and a fourth path portion away from the horizontal obstacle.

[0129] The chambers 211 may be connected by openings arranged to create a series of chambers 211 with staggered openings between the series of chambers 211. For example, rather than all adjacent chambers including openings, only certain chambers 211 may be connected to provide a particular serpentine path through the disk.

[0130] Additional example implementations for the serpentine path may include a circular or winding path.The winding path provides a circular path for the serpentine path.

[0131] Additional example embodiments of the serpentine path may include one or more valves between chambers 211 to slow down the air flow. The valves may be porous materials, such as foam. The valves may further increase the time the air spends in the serpentine path and the path of the illumination light.

[0132] Fig. 10A and Fig. 10B An example charging module 300 for a sanitization system is illustrated. Fig.11A and Fig. 11B An example charging module 300 for a disinfection system is illustrated. The charging module 300 may include a charger 301 and a collection plate 302. In some examples, the charging module 300 charges plume air naturally exhausted from the toilet 100. In some examples, the charging module 300 charges mist from a misting system that merges with the plume air.

[0133] As the air / mist is drawn from the bowl 101 through the disinfection system by the fan 110, the air / mist initially passes through the charger 301. The charger 301 may include a device to apply an electrostatic charge to the particles within the plume. The charger 301 ionizes the air around or within the plume using a high voltage that causes the air to break down and become conductive. Corona occurs when the potential gradient of the electric field around the charger 301 is greater than the dielectric strength of the air or plume.

[0134] The charger 301 may be a corona wire having a small diameter wire (eg, less than 100 microns). Fig. 11B The corona wire 301 is illustrated as running along the perimeter of the charging module 300 (eg, in an oval or teardrop shape). The corona wire may be an example of a dual conductor charger. The charger 301 may include a brush. The brush may be an example of a single conductor charger.

[0135] The charger 301 may include a capacitive plate (i.e., the corona wire may be omitted). The capacitive plate may be formed by a conductive sheet bonded to a dielectric material. The conductive sheet may be a foil. The dielectric material may be a plastic. A controlled bias may be selectively applied to the conductive sheet. For example, a power source may be connected to the conductive sheet and turned on and off by the controller 12. The controller 12 may apply a high voltage to the conductive sheet at periodic time intervals or in response to a flush cycle.

[0136] In some examples, an atomization system that generates fog or thick dry fog sets one or more parameters of the fog to promote corona charging. For example, the atomization system can set the particle diameter of the fog (e.g., 10 microns, 20 microns, 50 microns, or 100 microns). The particle size can be a maximum particle size or an average particle size. The atomization system can apply an electric charge to the fog. Although small thick fog / mist particles may already be charged, the charger 301 also applies a charge to any dust or microorganisms present. The charger 301 can apply a specific polarity (e.g., negative polarity) to the fog.

[0137] The negatively charged particles can then be drawn toward the positively charged collection surface. The surface can be positively charged by ion adsorption or other techniques. The collection surface is within an interior chamber of the disinfection system and is bathed in light (e.g., ultraviolet light) from a light source 144. The light is used to directly sterilize the particles drawn toward the positively charged collection plate 302.

[0138] As discussed in more detail, the charger 300 may also include a photocatalyst applied to the collection surface. The light source 144 may also activate the photocatalyst to enhance the effectiveness of the sterilization system. The light source 144 may simultaneously activate the photocatalyst and sterilize the particles adsorbed to the collection plate 302.

[0139] Furthermore, the collection plate 302 may be self-cleaning and may be easily removed for maintenance or cleaning.The collection plate 302 may be attached to the charging module 300 by clips or other quick connections.

[0140] Fig. 12A and Fig. 12B An example hydroxyl module 400 for use in a disinfection system is illustrated. Fig.13A and Fig. 13B An example hydroxyl module 400 for a disinfection system is illustrated. The hydroxyl module 400 may include a base structure 402 for a photocatalytic filter including a plurality of cells 401. Additional, different, or fewer components may be included.

[0141] The unit 401 of the photocatalytic filter may have various shapes. The unit 401 may be spherical, such as a bead. The unit 401 may be honeycomb-shaped (eg, hexagonal prisms).

[0142] The base structure 402 may be a reactor chamber enclosing the cells 401. The base structure 402 may be shaped as a container (e.g., a cage) in which the cells 401 are loosely housed and can move with the base structure 401. The base structure 402 may securely mount the cells 401 (e.g., a honeycomb structure).

[0143] The cell 401 may be hollow so that the air flows through the cell 401. In this case, the air flow is forced to be within a predetermined distance of the surface of the cell 401. The size of the passage through the cell 401 may be selected to be small enough to induce a sufficient reaction with the catalyst. However, the size of the passage through the cell 401 may be selected to be large enough to prevent a large amount of back pressure on the fan 110.

[0144] Unit 401 may be formed of glass or another material, the surface of which may have a catalyst applied. The catalyst may include titanium dioxide in anatase form applied to unit 401 as a coating.

[0145] Light source 144 can illuminate unit 401 to activate the catalyst on unit 401. The catalyst acts in response to the proximity of particles to unit 401. When the plume is released from toilet 100, some particles of the plume travel to unit 401 within a predetermined distance, thereby causing a reaction with the catalyst. The reaction can produce hydroxyl radicals or peroxides. The reaction can decompose any substance adhering to the particles in the plume. Viruses or bacteria can be killed or eliminated by the reaction. In addition, volatile compounds associated with odors can be decomposed by the reaction.

[0146] The hydroxyl module 400 can also cause a reaction with the mist from the misting system. Particles from the mist can adhere to particles from inside the toilet 100 or from the plume. When the mist flows into or near the unit 401, the hydroxyl module 400 causes a reaction with these particles.

[0147] Fig.14A and Fig. 14B An example cyclone separator module 500 for use in a disinfection system is illustrated. Fig.15A and Fig. 15B An example cyclone module 500 for a disinfection system is illustrated. The cyclone module 500 may include a plurality of cyclones 501, each cyclone 501 having a passage 502 therethrough. Additional, different, or fewer components may be included.

[0148] The cyclone module 500 is configured to remove aerosols from a plume or mist using centrifugal force. The cyclone module 500 may include a number of cyclones 501, each of which is relatively small to cause a low total pressure drop during the application of centrifugal force to separate aerosols from a plume or mist.

[0149] Fig.16 An example cyclone separator 501 is shown in more detail. The cyclone separator may include a cap portion 503, a longitudinal portion 504 and a tapered portion 505 that together form a passage 502 through the cyclone separator 501.

[0150] The tapered portion 505 may connect the first circular opening 506 to the second circular opening 507, the diameter of the second circular opening 507 being greater than the diameter of the first circular opening 506. The first wall extends from the first circular opening 506 to the second circular opening 507. The first pipe 508 extends from the second circular opening 507 to the third circular opening 510. The diameter of the second pipe 511 is less than the diameter of the second circular opening 507 and the second pipe 511 is disposed in the first pipe 508 to be separated from the second opening 507 by a distance. The wall 512 is located outside the first pipe 508 and at least partially surrounds the second pipe 511. The periphery of the cap 514 is fixed to the wall 512. The second pipe 511 passes through the cap 514. In one example, the diameter of the third circular opening 510 is the same as the diameter of the second circular opening 507.

[0151] The first circular opening 506 accelerates the air flow in the cyclone separator 501. The higher rotational speed exerts a centrifugal force on the particles suspended in the air, thereby pushing the separated portion toward the duct 508. The second duct 511 is used to separate the particles from the air as the air passes through the second duct 511 and the particles are pushed through the third circular opening 510.

[0152] The cyclone separator 501 can be formed of a transparent material such as plastic or glass. The walls of the cyclone separator 501 can be coated with a catalyst (e.g., a photocatalyst) so that particles separated from the air flow and resting against the walls of the cyclone separator react with the catalyst. All surfaces inside the cyclone separator can be continuously illuminated by the light source 144, thereby activating the oxidation process. The cyclone separator 501 allows the air / mist to have an extended residence time in the presence of the UV light and the catalyst, thereby increasing the efficiency of the UV light and the system as a whole. Therefore, the disinfection system is self-cleaning and requires little maintenance.

[0153] Fig.17A , Fig. 17B and Fig. 17C Examples of toilet types that can be combined with a tank disinfection system are illustrated. In any of these examples, the flush cycle can be a siphon flush in which water is released to the siphon nozzle to initiate the flush, or a wash flush in which water is released to the rim passage to initiate the flush.

[0154] Fig.17A A flapper system 600A is illustrated where flapper 610 seals the tank without releasing water until the flush cycle begins. Flapper 610 is hinged and opens slowly without damaging the seat. Float 604 can define a water line 605. Rim feed hose 603 can provide water to the rim passage through overflow tube 602.

[0155] Fig. 17BA canister system 600B is shown in which a canister 611 seals the water tank and does not release water until the flush cycle begins. Canister 611 includes a flush valve supported by a cylindrical canister coupled to the valve. When flushing begins, the canister lifts up to release the water. Instead, the opening is then slowly hinged on one side of the valve, as in the case of flapper 610, and the entire opening of the flush valve is opened in one position to allow a larger amount of water to flow into the valve simultaneously, thereby increasing the flushing capacity. The water line 605 is also defined by the float 604. A rim feed hose 603 can provide water to the rim passage through the overflow tube 602 and then through the canister 611.

[0156] Fig. 17C The dual flush tank system 600C can provide multiple flush types, such as full flush and half flush. The rod 607 can operate the plunger 606 in different ways to cause multiple types of flushes. The water line 605 is also defined by the float 604. The edge feed hose 603 can provide water to the edge channel through the overflow tube 602 separated from the plunger 606.

[0157] In any of these examples, the disinfection system 601 can be mounted to the interior of the tank in a predetermined relationship with an overflow tube 602 leading to one or more rim channels of the toilet 100. The disinfection system 601 can generate a fluid that travels through the overflow tube 602 and into the toilet bowl 101. The fluid can travel through a flush valve. The fluid can be a liquid, a mist, or a fog. The fluid can include hydrogen peroxide (H2O2). The fluid can be lighter than water but heavier than air. Therefore, gravity allows the fluid to travel through the overflow tube 602 and / or the flush valve into the toilet bowl 101. The fluid can fill the toilet bowl 101 from the bottom up.

[0158] First, the fluid can clean the interior passages of the toilet 100 and bowl 101. The fluid controls odors (e.g., volatile compounds), reduces mold in rim passages, and cleans the interior of the toilet bowl.

[0159] Furthermore, the fluid may interact with any embodiment of the plume cleaning assembly to clean the plume and other aerosols found within the toilet bowl 101 .

[0160] Fig.18The disinfection system in the water tank of a toilet including a tank system 600B is illustrated. The disinfection system 601 may include a misting device. In some examples, the fan 110 may direct the dense mist or fog toward the overflow pipe 602. To help transfer the fog from the water tank to the toilet bowl, the water tank cover may be tightly sealed (e.g., using an additional sealing mechanism). In addition, the concentration of the dense fog in the toilet bowl may be adjusted by adjusting one or more other seals. Example seals may be located between the edge and the toilet seat and / or between the toilet seat and the cover. The disinfection system 601 includes an atomizer housing located in the water tank of the toilet and a regulating unit that generates fog and provides the fog through at least one channel of the toilet.

[0161] Fig.19A and Fig.19B An example implementation of a disinfection system with a flapper flushing system 601 is illustrated. The disinfection system 601 may include a reservoir 621, a battery 623, a connecting tube 624, and an atomizer 625. The atomizer 625 includes components enclosed in an atomizer housing. Alternatively or additionally, the reservoir 621 and the housing including the reservoir 621 and the battery 623 may be an atomizer housing. The reservoir 621 may store a fluid for generating mist. The battery 623 may provide power to a pump (not shown) for delivering the fluid to the atomizer 625 through the connecting tube 624. The connecting tube 624 may be fixed to a cap 632 of the reservoir 621. The connecting tube 624 connects the regulating unit or the atomizer 625 to the overflow mechanism 602. The regulated flow flows through the overflow mechanism 602 to at least one channel of the toilet 100.

[0162] In addition to the transfer of fluids, the connection tube 624 can be associated with a power cable (eg, the connection tube 624 can be coupled to a power cable) for providing power to the atomizer 625 .

[0163] Fig. 20 An example piezoelectric atomizer 625 for a disinfection system is illustrated. The fluid supplied from the connection tube 624 is provided to a housing 631, which includes a piezoelectric element 633, a trumpet 634, and a propulsion fan 635. The piezoelectric element 633 can generate ultrasonic vibrations that break up liquid having particles of approximately a predetermined size (e.g., tens of microns). The trumpet 634 in the spray nozzle propels the particles into a mist. The propulsion fan 635 provides flow for the fluid including the particles.

[0164] Fig.21A and Fig. 21BAn example implementation of a disinfection system 601 is illustrated with a baffle flushing system 610. The embodiment may include an expandable hose 641 to connect the disinfection system 601 with an overflow pipe 602. The embodiment may include a vent 643 (one or more vents) for allowing air to enter the disinfection system 601 to generate a mist.

[0165] Fig.22A and Fig. 22B A sprayer 650 is shown for use in a disinfection system. The sprayer 650 may be gravity fed, optionally with the assistance of a fan 635, as the air flows downwardly under gravity. The air may flow through a filter, such as a carbon bed 660. The sprayer 650 is a device for spraying a liquid (e.g., hydrogen peroxide) as a fine spray.

[0166] Fig.23A and Fig. 23B Another embodiment is shown, in which the fluid from the disinfection system 601 can be electrolyzed water. As discussed in the examples herein, the electrolyzed water reactor 60 can perform electrolysis within the disinfection system 601 via a cathode 61 and an anode 62. The water tank 108 can include a separate housing that defines the reactor 60 and includes an anode compartment for the anode 62 and a cathode compartment for the cathode 61, which can be separated by a porous partition 63. In the anode compartment, a cleaning solution (alkaline) is produced, while in the cathode compartment, a disinfection solution (acidic) is produced.

[0167] Figure 24 to Figure 26 An example valve system for overflow pipe 602 and disinfection system 601 is shown. Fig.24 In , the overflow pipe 602 is closed to the overflow of water from the water tank and the disinfection system 601 is open to the overflow pipe 602. Fig.25 In the embodiment, the overflow pipe 602 is open to the overflow of water from the water tank and the disinfection system 601 is closed to the overflow pipe 602. The valve system can be controlled by the water level W in the water tank. Fig.26 An example of an electronic controller controlling a valve system is illustrated.

[0168] Fig.24 An overflow tube 602 is shown connected to the disinfection system 601 via a hose 641 and a valve system 661. The valve system 661 may include an overflow valve member 662, one or more floats 663, and a disinfection fluid valve 664.

[0169] When the water in the water tank is below a predetermined water level, the overflow valve member 662 closes the overflow pipe 602 and the disinfection fluid valve 664 opens to allow disinfection fluid to flow from the disinfection system 601 through the opening 665 into the overflow pipe 602 to reach one or more channels of the toilet and enter the edge opening, and finally enter the toilet bowl. The disinfection fluid valve 664 can be biased open by a spring or gravity. The disinfection fluid valve 664 can be connected to the overflow valve member 662 so that when the overflow valve member 662 is opened, the disinfection fluid valve 664 closes the opening 665. The disinfection fluid valve 664 can pivot at the pivot 667 to open and close the opening 665 between the hose 641 and the overflow pipe 602.

[0170] As water fills the tank around the overflow tube 602, the upward buoyancy on the one or more floats 663 lifts the one or more floats 663 coupled to the overflow valve member 662. As the floats 663 are pushed upward, the opening 669 is exposed to allow water to flow into the overflow tube 602. At the same time or nearly at the same time, as the overflow valve member 662 moves upward, the disinfection fluid valve 664 can be pulled closed by the overflow valve member 662 to close the opening 665.

[0171] Fig.26 The controller 12 is shown in communication with the valve array 675. The valve array 675 may include at least one valve that opens the disinfection system 601 to the overflow pipe 602 and at least one valve that opens the overflow in the tank to the overflow pipe 602. The controller 12 may generate valve commands for each valve of the valve array 675.

[0172] Controller 12 may cause overflow tube 602 to be open by default. In response to a cleaning cycle, controller 12 may close the valve corresponding to overflow tube 602 and open the valve corresponding to disinfection system 601 to allow disinfection fluid to flow through overflow tube 602 to the rim opening of the toilet bowl.

[0173] Fig.27A and Fig.27B A first embodiment of a sanitizing system for a dryer 700 is illustrated. Fig.27A is a front view of the dryer 700, and Fig.27B 700. The dryer 700 can be mounted to a wall via a support 702 and provide a sterile towel 701 for drying hands or other objects. The towel 701 can be sterilized, irradiated, or otherwise cleaned to remove biological materials. In addition to the following description, it should be understood that any of the modules (e.g., the impactor module 200, the electrostatic module 300, the hydroxyl module 400, and the multi-stage cyclone separator module 500) can be disposed in the dryer 700 alone or in combination.

[0174] Fig.28A detailed view of a first embodiment of a disinfection system for a dryer 700 is illustrated. The dryer 700 includes an air inlet 711, an atomizer (e.g., a piezoelectric atomizer) 712, a light source 713, foam 714, a fan 715, a pump 716, a controller 717, a reservoir 718, and a towel 701. The air inlet draws air from the surrounding environment. The controller 717 can be implemented by a control system described herein.

[0175] The atomizer 712 can obtain chemicals and / or solutions (e.g., hydrogen peroxide or electrolyzed water) from a reservoir 718 via a pump 716. The atomizer 712 can be a sprayer including a horn and a piezoelectric element (e.g., Figure 4B ), the nebulizer receives and meters the liquid flow and generates mist by vibration. The nebulizer 712 may include an interdigital transducer configured to generate surface acoustic waves that atomize the liquid and leave the nebulizer, a power circuit configured to provide a radio frequency signal to the surface acoustic wave, and a drive circuit configured to control an actuator to meter the liquid flow entering the nebulizer. The nebulizer 712 may include an atomizer rod configured to provide mist in a configurable predetermined direction.

[0176] Light source 713 can be ultraviolet light that illuminates the mist. Light source 713 can include one or more LED lights. The mist is provided to open-cell catalytic foam 714. Foam 714 slows down the mist or air flow to spend more time being illuminated by light source 713. Particles in the mist also adhere to foam 714. Light source 713 activates the catalyst in foam 714 to further oxidize any particles in foam 714. Through these reactions, hydroxyl radicals and peroxides can be generated, and the hydroxyl radicals and peroxides are included in the air flow that blows through towel 701.

[0177] The fan 715 generates an air flow to draw the air through the foam 714 and the mist generated by the atomizer 712 into the towel 701. The towel 701 may be in the shape of a sock or a windsock. The towel 701 may have an open end that is fixed to the dryer 700. The other end of the towel 701 may be closed, but the towel 701 is semi-porous so that some air escapes. The air flow expands the towel 701. In some examples, the towel 701 has a smaller opening on the bottom end, which is equivalent to a windsock. The towel 701 may be formed of microfiber.

[0178] The control board (controller 717) can generate command signals for the atomizer 712, fan 715, light source 713, and pump 716. When the dryer 700 is turned on, which can be triggered by a motion sensor, all systems can be turned on. The controller 717 can provide specific command sequences to enable the light source 713, fan 715, pump 716, etc. at specific times.

[0179] FIG. 27A to FIG. 27B An embodiment having a tapered towel 701 is shown. FIG. 29A to FIG. 29B and FIG. 30A to FIG. 30B An embodiment having a cylindrical towel 701 is shown. Fig. 30A Flow 720 is shown passing through dryer 700 in a generally vertical direction to expand towel 701 . Fig. 30B A cover or hatch 721 for adding chemical solutions or electrolyzed water to the dryer 700 is shown.

[0180] like Fig.31 As shown in more detail, Fig. 30A and Fig. 30B Embodiments of can include a sanitizing system for a dryer 700, a disposable towel dispenser including a towel 722. The towel dispenser can be formed as a cylindrical tube 723 surrounding at least a portion of a spindle nozzle 724.

[0181] Atomizer 712, light source 713 and fan 715 can operate in a similar manner as described above. A pump 716 and controller 717 can also be included. In this case, the air flow allows the towel dispenser to advance another section of disposable towel to the end of the dryer 700. The air flow expands the towel section. The user can use the expanded, disinfected towel and remove the towel for disposal. The next time the fan is started, another towel section will move into place.

[0182] Fig.32A , Fig.32B , Fig.33A and Fig.33B Operation of the first and second embodiments of dryer 700 by user 750 is illustrated. When user 750 enters field of view 731 of sensor 730 (e.g., optical sensor or other presence or motion sensor), controller 717 can trigger operation of atomizer 712, light source 713, and fan 715. Towel 701 expands and is disinfected. User dries user's hands on towel 701. Towel 701 can be removed by user 750 (e.g., along perforations).

[0183] Fig.34An example controller for a disinfection system is illustrated. Control system 410 can implement any controller described herein, including controller 10 and controller 717. Control system 410 can include processor 310, memory 352, and communication interface 353 for interfacing with device or the Internet and / or other network 346. In addition to communication interface 353, sensor interface can be configured to receive data from sensors described herein or data from any source for analyzing user input, user gestures or positions, characteristics of air and / or water, or operation of the apparatus described herein. Components of control system 410 can communicate using bus 348. Control system 410 can be connected to a workstation or another external device (e.g., control panel) and / or a database for receiving user input, system characteristics, and any values ​​described herein.

[0184] Optionally, the control system 410 may include an input device 355 and / or sensing circuitry in communication with any of the sensors. The sensing circuitry receives sensor measurements from the components as described above. The input device 355 may include a switch 150, a touch screen coupled to or incorporated with the mirror, a keyboard, a microphone for voice input, a camera for gesture input, and / or other mechanisms.

[0185] Optionally, the control system 410 may include a drive unit 340 for receiving and reading a non-transitory computer medium 341 having instructions 342. Additional, different, or fewer components may be included. The processor 310 is configured to execute instructions 342 stored in a memory 352 for executing the algorithms described herein. The display 350 may be supported by the frame. The display 350 may be combined with a user input device 355.

[0186] Fig.35 A flow chart for controlling a system 410 is illustrated. The actions of the flow chart may be performed by any combination of the control system 410, a network device, or a server. A portion of one or more actions may be performed by the appliance. In addition, different or fewer actions may be included.

[0187] In action S101, controller 410 (e.g., via processor 310) receives data to indicate toilet seat use. The data may be a timer or sensor data. The sensor may be a pressure sensor that indicates that a user has sat down on the toilet seat (e.g., pressure increases) or that a user has stood up after a predetermined time indicating use of the toilet seat (e.g., pressure decreases). The sensor data may be a user input (e.g., a motion sensor or a gesture sensor).

[0188] In action S103, controller 410 (eg, via processor 310) causes the atomizer to generate a mist configured to adhere to particles in the plume discharged from the toilet. The mist may be diffused or otherwise propelled into the toilet bowl.

[0189] In action S105, the controller 410 (e.g., via the processor 310) adjusts the mist according to any of the modules described herein (including electrostatic charging, catalyst, cyclone separator, or impactor). In action S107, the controller 410 (e.g., via the processor 310) triggers or continues to apply light (e.g., ultraviolet light) from a light source.

[0190] In action S109, the controller 410 (e.g., via the processor 310) reports the disinfection or cleaning process, for example, via the display 350, the speaker 351, or the communication interface 353. The display 350 may indicate the status of the cleaning cycle being performed or having been performed. The status may be displayed in response to the generation of mist or another stage of the cleaning cycle.

[0191] Fig.36 A flow chart for controlling a system 410 is illustrated. The actions of the flow chart may be performed by any combination of the control system 410, a network device, or a server. A portion of one or more actions may be performed by the appliance. In addition, different or fewer actions may be included.

[0192] In action S201, the controller 410 (e.g., via the processor 310) generates a mist command. The mist command may instruct the mist generator to turn on or enter an active mist mode. The mist generator may include a transducer or piezoelectric element that generates a mist cloud from a liquid having disinfecting properties. The liquid may include a cleaning compound or a chemical having disinfecting properties.

[0193] In action S203, controller 410 (e.g., via processor 310) generates a fan command. The fan command may instruct the fan to turn on or enter an active air circulation mode. The fan and the spray generator may be supported by an air cleaner housing that may be integrated into the toilet seat assembly. The fan may include blades or impellers configured to draw air from a fan inlet and discharge air from a fan outlet. The air may include a cloud of particles that includes at least a portion of the mist from the mist generator.

[0194] The controller 410 may generate a mist command (act S201) and a fan command (act S203) in any order, in a predetermined sequence, and in response to various triggers, which may have a predetermined time interval delay between the mist command and the fan command.

[0195] An example trigger is a time period or schedule. When a predetermined time has passed since the last mist command, the controller 410 initiates the mist command. Example time periods may include 10 minutes, 1 hour, or 2 hours. The schedule for the mist command may be user configurable. The controller may then initiate a fan command, such as after a second time period, to recirculate the mist and / or drive the mist to an electrostatic charger.

[0196] One example trigger is a flush cycle. The flush cycle may be initiated by a user input to flush the toilet or by sensor data detecting a presence near the toilet, the absence of such a presence, or any other sensor described herein. In one example, in response to the flush, the controller 410 initiates a misting command to fill the bowl with a mist cloud and then initiates a fan command to recirculate the mist and / or drive the mist to an electrostatic charger.

[0197] In action S205, the cloud is provided to an electrostatic collector. The electrostatic collector removes particles from the cloud. The cloud in the air may be provided in part by internal passages in the air cleaner assembly.

[0198] In action S207, particles are collected at an electrostatic collector. The electrostatic collector may be passive, including a charge provided by the material forming the electrostatic collector or applied during the manufacturing process of the electrostatic collector. That is, the electrostatic collector may be permanently charged with an electrostatic charge. In another example, the controller 410 may provide an electrical diagram to the electrostatic collector.

[0199] In action S209, the cloud is recirculated from the electrostatic collector to the mist generator. The cloud may be recirculated via another air passageway that leads from the electrostatic collector back to the mist generator. However, the recirculation path may include a toilet bowl. That is, the collected static electricity may discharge the air cloud to the bowl, which is collected by the inlet of the fan. The controller 410 may receive sensor data and trigger a recirculation sequence based on the sensor data.

[0200] The processor 310 may be a general or special purpose processor, an application specific integrated circuit (ASIC), one or more programmable logic controllers (PLC), one or more field programmable gate arrays (FPGA), a set of processing components, or other suitable processing components. The processor 310 is configured to execute computer code or instructions stored in the memory 352 or received from other computer readable media (e.g., embedded flash memory, local hard disk storage, local ROM, network storage, remote server, etc.). The processor 310 may be a single device or a combination of devices, such as associated with a network, distributed processing, or cloud computing.

[0201] The memory 352 may include one or more devices (e.g., memory cells, memory devices, storage devices, etc.) for storing data and / or computer code to complete and / or facilitate the various processes described in the present disclosure.
