Description

[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 252,697, filed October 6, 2021, and U.S. National Patent Application No. 17 / 949,669, filed September 21, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application generally relates to toilet seat assemblies for reducing or preventing air plumes from being expelled from the toilet bowl. Background Technology

[0003] Air typically consists of very small particles or droplets suspended in the air. These aerosols are particularly prevalent in enclosed spaces, and even more so in enclosed spaces with water. For example, in a bathroom, aerosols can be emitted from several places, especially the toilet; aerosols emitted from the toilet can be referred to as a toilet plume.

[0004] Aerosols can be removed from the air we breathe by the human respiratory system. However, some aerosols may be toxic and may even carry viruses into the body. The problem of aerosols can be mitigated through air disinfection. It would be advantageous to provide toilets with internal sealing systems that prevent toilet plumes from escaping from the toilet bowl. Attached Figure Description

[0047] The following embodiments include systems, apparatus, and methods for disinfecting and / or sterilizing one or more surfaces and / or one or more spaces associated with a toilet bowl. Regarding toilets, there are two specific target areas: managing plumes and disinfecting toilet surfaces or at least surfaces that come into human contact. A plume is a cluster of tiny particles or droplets dispersed into the air due to flushing the toilet. A plume can include bacteria, pathogens, or feces. Every person using the toilet comes into contact with the seat or lid. This person not only has the potential to spread their pathogens to these surfaces but also poses a risk of spreading pathogens to others.

[0048] The following disinfection and / or sterilization systems, devices, and methods can be incorporated into toilet seat assemblies. Typically, a toilet seat assembly may include a cover, a seat, and one or more passageways or cavities configured for delivering disinfecting fluids.

[0049] Example disinfection fluids may include bactericides, disinfectants, or other solutions. The container may include an opening for receiving the bactericide into the container. A bactericide may be hydrogen peroxide (H₂O₂). Hydrogen peroxide has antiviral and antibacterial properties. Hydrogen peroxide is an example antibacterial agent because it kills bacterial cells by disrupting cell walls. Hydrogen peroxide is also more effective than chlorine bleach in contacting and killing mold on porous surfaces. As a bactericide, hydrogen peroxide can be applied to a surface and then air-dried. Other solutions that can be stored in the container may include quaternary ammonium, tetraacetylethylenediamine, phenol, isopropanol, sodium carbonate, peroxide; tetraacetylethylenediamine, ethanol, sodium hypochlorite, octanoic acid, or sodium chlorite.

[0050] As an alternative to these chemical solutions, the tank may include electrolyzed water. Electrolyzed water may be referred to as electrolyzed oxidized water, electroactivated water, or electrochemically activated aqueous solution. Electrolyzed water can be produced by electrolyzing water in which sodium chloride is dissolved (e.g., ordinary water or tap water). Electrolysis can produce hypochlorous acid and sodium hydroxide. Electrolysis may include connecting a direct current (DC) power supply to multiple electrode plates made of conductive materials such as metals.

[0051] Figure 1A and Figure 1B The illustration shows an example toilet seat 100 and a gasket system, which includes a first seal (gasket) 112 and a second seal 104 (gasket). Figure 2A The illustration shows an example toilet seat assembly. Figure 2B The illustration shows an example hinge portion 111 of a toilet seat assembly. Figure 2C The illustration shows an example rear view of hinge section 111.

[0052] Figure 1BA hinge assembly 10 is illustrated, which can be located behind the toilet seat 100 and below the lid 103. The toilet seat 100 is rotatably connected to the toilet bowl via a hinge. The hinge assembly or portion 111 may include one or more sterilization components as described herein.

[0053] Figure 1B A valve 120, which can be engaged by a protrusion of the cover 103, is also illustrated, and will be discussed in more detail below. The cover 103 may include a sidewall enclosing the toilet seat 100. As described in the above example, disinfectant fluid can exit the toilet seat assembly along one or both of two paths. A first path, through one or more channels or openings, allows disinfectant fluid to flow from the tank of the toilet seat assembly into the toilet bowl. A second path, through the valve 120, allows disinfectant fluid to flow into the toilet seat 100.

[0054] The first seal 112 may be a hinge seal configured to seal the space between the toilet seat 100 and the edge of the toilet bowl. The hinge seal may be connected to a hinge and / or integrated into a hinge assembly or portion. The first seal 112 may also be a baffle that partially slows or prevents the flow of disinfectant material into the toilet bowl.

[0055] The second seal 104 may be a peripheral seal that slidably engages with the lip of the toilet seat 100. Figure 1B Rib 105 is also illustrated to prevent disinfectant fluid and / or plume from escaping through or across the hinge. In some examples, rib 105 is a third seal, while in other examples, the second seal 104 and rib 105 are integrated into a single component.

[0056] On cover 103, an internally integrated cover baffle design (e.g., second seal 104) can optimize the use and sterilization effect of H2O2 (either through overmolding or by welding / adhesive bonding). Furthermore, a rear cover peripheral seal (e.g., first seal 112) can prevent the plume from escaping across the hinge area. The rear cover peripheral seal may also include a side-wrapping geometry.

[0057] On the ring or toilet seat 100, a mechanically extruded scraping seal (e.g., a thermoplastic elastomer TPE or thermoplastic vulcanized TPV soft material) along the periphery of the ring provides an easy-to-install, low-cost, and durable gasket design. On the ring or toilet seat 100, the scraping seal helps retain H2O2 mist during the atomization process, improving the efficiency of surface biocidal activity and reducing the amount of chemicals required for efficacy.

[0058] Figure 3A An example outer gasket 106 for a toilet seat is illustrated. The outer gasket 106 may be an outer peripheral seal that is attached to the lid and configured to engage with the toilet seat 100. Figure 3B and Figure 3C The illustration shows details of the outer washer 106. The outer washer 106 may include an engagement portion 107, which includes a groove 109 that mates with a track 108 of the toilet seat 100. The track 108 may include a lip or another protrusion that fits within the groove 109 of the outer washer 106, or otherwise slidably engages the outer washer 106.

[0059] Figure 4 The illustration depicts the operation (e.g., pop-out function) of a valve 120 for a disinfectant fluid. The valve 120 has an opening leading to a tank 118. The valve 120 is operable to receive or release a disinfectant fluid. The valve 120 can meter or control the flow rate of the disinfectant fluid. The valve 120 may include a cap 122 and a restrictor 123. A cover 103 includes a protrusion 121 in a predetermined position that engages with the valve 120 and releases disinfectant material into the toilet bowl. The protrusion 121 can be positioned according to a first strut 124 and a second strut 125 of the cover 103, the first strut 124 and the second strut 125 being arranged to align the protrusion 121 with the valve 120. The valve 120 is operable in a first position to at least partially prevent disinfectant material from leaving the tank 118, and is operable in a second position to release disinfectant material from the tank 118 into the toilet bowl upon engagement with the protrusion 121.

[0060] Figure 5 The diagram illustrates the path P of the disinfecting fluid. Path P can be defined by at least one ridge feature 126. Path P can be defined by at least one step feature 127. Path P can be defined by at least one channel feature 128. Figure 6 Another view of the hardware for the path P of the disinfecting fluid is illustrated, including step features 127 and channel features 128. Path P may be defined by an open area at the rear of the seat assembly, which allows for air recirculation so that the siphon toilet can flush without problems. The geometry within the hinged shroud can be configured to allow all atomized air to escape and clean in each atomization cycle. In some examples, the atomized H2O2 may flow in a liquid-like manner and be discharged onto potentially soiled surfaces.

[0061] Channel feature 128 can provide several advantages. At some point in the flushing and / or cleaning cycle, channel 128 is configured to provide air recovery for siphon flushing. At some point in the flushing and / or cleaning cycle, channel 128 is configured to provide disinfecting fluid to the toilet bowl.

[0062] Channel feature 128 can provide an overflow passage in case the user refills the chamber with excessive disinfectant fluid, and ensure that the atomizing device remains above the waterline. The passage also provides a deodorization solution by operating a fan (air flows through the chamber via the atomizing device or fan) when used as H2O2 vapor to eliminate odors and flow through a filter (electrostatic or other filtration technology).

[0063] Figure 7A and Figure 7B The illustration shows an example electrical connection for a toilet seat assembly. A power supply unit 130 may include a wire 131 and a plug connected to the toilet seat assembly. The power supply unit 130 can supply current to any of the devices described herein, including fans, mist generators, or electrolyzers. One of the posts 133 used to mount the toilet seat assembly may be connected to and supply current through the wire 131. The mounting plate 132 may be reversible, allowing the power supply unit 130 and the wire 131 to be positioned on either side of the toilet seat assembly and on either side of the toilet.

[0064] Figures 8A to 8D An example mounting plate for electrical connections is illustrated. Mounting plate 132 may include various terminals 134a to 134d of different shapes and sizes. Figure 9A and Figure 9B The illustration shows an example mechanical valve 120 used for disinfecting fluids.

[0065] Figures 10A to 10C The illustration shows an example mechanical valve 120 for disinfecting fluids, wherein... Figure 10B The mechanical valve 120 shown in the diagram is in the closed position and in Figure 10C The mechanical valve 120 shown in the diagram is in the open position. The valve 120 may include a valve hinge 151 offset from the center of the valve 120. The offset position of the valve hinge 151 can cause the valve 120 to open wider and place more weight of the valve 120 on the open side of the valve 120, such that when the protrusion 121 of the cover 103 is not in contact with the valve 120, gravity causes the valve 120 to close.

[0066] Figures 11A to 11B Another example mechanical valve 140 for disinfecting fluid is illustrated. Valve 140 may include a nozzle 141 configured to limit the amount of disinfecting fluid (e.g., H2O2 mist) flowing into the toilet bowl and preferentially deliver it above the ring when the lid is closed. Nozzle 141 may include a curved shield 143 extending into the opening of the chamber and limiting the flow of disinfecting fluid, and an opening 142 providing a path for the disinfecting fluid to exit the chamber. Figure 12 The illustration shows details of an example mechanical valve 140 for use with disinfectant fluid. Nozzle 141 is an example flow limiter integrated with valve 120 and configured to meter the disinfectant material flowing into the toilet bowl.

[0067] When valve 120 is closed, nozzle 141 allows mist to flow into the toilet bowl; when valve 120 is open, nozzle 141 reduces / stops the flow of mist into the toilet bowl. One advantage is that it increases the amount of mist on top of the toilet seat 100 or ring, thereby improving chemical application and surface disinfection effectiveness. The misted air above the toilet bowl surface helps to actively kill / reduce polluting aerosols emitted from the toilet bowl.

[0068] The following embodiment illustrates an example of airflow and disinfectant fluid generation in a toilet seat assembly. A fan provides airflow to the spray nozzle. At the spray nozzle, liquid is carried to the mist-generating nozzle by capillary action or otherwise. A lip in the tank defines the water level and directs the mist into the toilet bowl.

[0069] Figure 13 The illustration shows an example airflow for a toilet seat assembly. The housing 118 can have various shapes and locations. Figure 13 In the middle, the box 118 defines an upstream air passage 117 that provides a path to the box and a downstream passage 119 that provides a path away from the box 118.

[0070] Figure 14A and Figure 14B An example hinge plate 150 for a toilet seat assembly is illustrated. The hinge plate 150 includes at least one orifice for delivering disinfectant material to the toilet bowl. The hinge plate 150 may support a filter.

[0071] Figure 15A and Figure 15B The illustration shows example air ducts 161 and 162. A filter tray supports a filter 155 for the toilet seat assembly. A fan behind a fan shroud 164 provides airflow to draw disinfectant material through the filter and hinge plate orifices. The fan facilitates the flow of the disinfectant fluid.

[0072] Figure 16 An example drain cap 170 for a toilet seat assembly is illustrated. Drain cap 170 can be connected to a tank 118 to provide an access point and to drain from the tank 118. Drain cap 170 may include a sacrificial plug connected to drain cap 170 or tank 118. Drain cap 70 can be coupled to a tube member supporting the suction material. The term "sacrifice" can mean that drain cap 170 is sacrificed to disable or prevent unauthorized use of the toilet seat assembly. Drain cap 170 can be connected to the suction material.

[0073] The threads on the discharge cap 170 located at the bottom of the housing 118 facilitate the assembly of the atomizing device into the housing 118 and provide access for maintenance (replacing modules and / or wick material).

[0074] The drain cap 170 can be designed to insert a threaded / clogging feature made of a material that can withstand H2O2 but dissolves upon exposure to unsafe or highly irritating cleaning agents. Upon dissolution, the liquid will safely drain from the tank 118 and into the tray, and then into the toilet bowl. Therefore, when the toilet seat is misused, the drain cap 170 is sacrificed to allow for the rapid removal of unauthorized materials used in place of the disinfecting fluid from the toilet seat assembly.

[0075] When the sacrificed cap is dissolved or otherwise removed (e.g., for maintenance), the toilet seat assembly may need to be returned to the manufacturer or a service provider to replace the discharge cap 170. Figure 16 The illustration also shows a suction material 171, which can be configured to connect to a discharge cap to assist the flow of disinfectant material to valve 120.

[0076] Figure 17 The illustration shows an example toilet seat assembly 200 including multiple air paths as indicated by arrows. The toilet seat assembly 200 includes a filter tray 201, a filter 202, a separator 203, an odor module 204, a suction compartment 205, a sprayer 206, a fan 207, a cover 220, and a lid 101 with a protrusion 221. The portion of the toilet seat assembly 200 other than the toilet seat 100 and lid 101 may be referred to as a hinge structure. Electrical components such as the fan 207, sprayer 206, and optional odor module 204 may be electrically connected to a power supply and / or controller. Additional, different, or fewer components may be included.

[0077] Figure 17 The toilet seat 100, which is not visible in the center, is rotatably connected to the toilet bowl via a hinge of the toilet seat assembly 200. A post 133 connects the toilet seat assembly 200 to the toilet.

[0078] Airflow originates below the toilet seat assembly 200. One or more vents 227 may be located on the bottom of the hinge structure or on the side of the toilet seat assembly 200. A fan 207 is configured to direct airflow through the vents 227 into the hinge structure. A first chamber in the toilet seat assembly 200 is a filter chamber 202. The filter chamber 202 may include a filter for removing particles from the airflow. The filter chamber 202 may include a filter tray that slides out relative to the hinge structure. The filter tray can be removed for mounting a filter (filter fabric) within it. Alternatively, the filter tray may be formed of an electrostatic material. An example material is polypropylene. Electric charge can electrostatically collect particles from the airflow.

[0079] In some examples, the airflow then flows through fan 207. In other examples, air flows adjacent to fan 207. The space surrounding the fan is fan compartment 223.

[0080] After fan compartment 223, the airflow enters bifurcation chamber 224. In bifurcation chamber 224, separation device 203 splits the airflow into two streams. One stream (flowing towards...) Figure 17 The left side of the flow travels to the odor module 204, and another flow (flows towards) Figure 17 (On the right side) proceed through the open cover 220.

[0081] Odor module 204 may include a tray that is removable from toilet seat assembly 200. Figure 28 (As shown in the diagram). The odor module 204 may include a latch or lip that flexes to engage with a protrusion in the toilet seat assembly 200. The odor module 204 may include a replacement cartridge with a predetermined odor. The odor emitted by the odor module 204 may mask any toilet odor. The odor may smell refreshing to the user. The material of the odor module 204 may evaporate into the air. The material of the odor module 204 may include oil or other liquids.

[0082] Separation device 203 is used to separate the first flow (flow direction) Figure 17 (left side of the middle) and the second flow (flow direction) Figure 17 (On the right side of the image) to separate the odor from the hydrogen peroxide. This is because if hydrogen peroxide and odor share the same space, the hydrogen peroxide will break down the odor.

[0083] The second stream enters the disinfection chamber 225, where hydrogen peroxide is added to the stream. The wick compartment 205 in the hinged structure includes a wick material. The wick material 285 can be made of cotton or fabric. The wick absorbs the disinfectant fluid and delivers it to the sprayer 206 via capillary action.

[0084] The cartridge compartment 205 and the sprayer 206 can be connected together via a spray cap 265. The spray cap 266 may be made of rubber. The sprayer 206 may include a stainless steel frame and piezoelectric elements. The cartridge compartment 205 contains the disinfectant fluid. In some cases, the cartridge contains all the disinfectant fluid. In some cases, there may be some liquid accumulation in the cartridge compartment 205 adjacent to it. The spray cap 265 can apply pressure to the cartridge to keep it tightly closed within the spray compartment 205. The spray cap 266 can be twisted to lock the spray cap 265 to the cartridge compartment 205.

[0085] The sprayer 206 atomizes the disinfectant fluid into a mist or fine particle spray. The mist is sprayed into the disinfection chamber 225 and enters the airflow. The airflow carries the disinfectant particles to the toilet seat 100, where they disinfect the surface of the toilet seat 102. The sprayer 206 is configured to spray fine particles of the disinfectant fluid into the airflow from the fan 207.

[0086] It should be noted that even without fan 207, sprayer 206 can operate to fill disinfection chamber 225 with disinfectant particles. However, the air movement provided by fan 207 plays a crucial role in the distribution of disinfectant particles. Furthermore, fan 207 can be cyclically turned on and off along with sprayer 206. Fan 207 can operate to generate dry air (i.e., air without disinfectant particles) after sprayer 208 is turned off to aid evaporation in disinfection chamber 225. Increased evaporation in disinfection chamber 225 causes toilet seat 100 to dry faster. Additionally, as water evaporates, the concentration of hydrogen peroxide increases, and the effectiveness of the disinfectant fluid can be enhanced.

[0087] Figure 18 and Figure 19 An embodiment of the toilet seat assembly 200 without the odor module 204 and separation device 203 is illustrated. In this example, almost all of the forced air flows through the toilet seat assembly 200. That is, the airflow passes through the inlet vent, through the filter 202, and directly to the top of the sprayer 206, where disinfectant particulate mist is added to the flow, and then flows out of the toilet seat 100 through the opening of the shroud 222. In this embodiment, the fan 2007 may be arranged vertically or in another location.

[0088] Figure 20A , Figure 20B and Figure 20C An example removable disinfectant cover 222 is illustrated. The cover is configured to pivot about an axis, wherein a protrusion 221 applies a downward force to the cover 222. The cover or hinge plate is configured to open under the force from the protrusion 221 to deliver disinfectant material to the toilet bowl for release of disinfectant material into the toilet bowl when the protrusion 221 presses against the cover 222 in a predetermined position.

[0089] Pivoting relative to the toilet seat assembly 200 can be achieved using a boss 266 that pivots in a recess or recess within the toilet seat assembly 200. The boss 266 may be layered to create a uniform gap between the two sides of the cover 222 relative to the toilet seat assembly 200. The boss 266 or the mating recess or recess may include two hinge plates to secure the hinge plates or cover 222 to and from the toilet seat assembly 200 by rotation. The cover 222 or hinge plates are removable as the cover 222 rotates away from the toilet seat assembly 200 due to the forces exerted on the toilet seat assembly by the boss 266 and / or recess.

[0090] For example, the cover 222 can be removed by over-rotation of the cover 222. Over-rotation can mean that the cover 222 rotates relative to the toilet seat assembly 200 by an amount exceeding the amount of rotation that the protrusion 221 can apply. Over-rotation can be greater than 90 degrees. When the cover 222 is over-rotated, the protrusion 266 applies force to the toilet seat assembly 200 to push the cover 222 away from the hinge portion and eject the cover 222 into engagement. In this way, the user can remove the cover 222 for maintenance of the toilet seat assembly 200. Examples of maintenance include refilling with disinfectant fluid, replacing the cartridge, removing the clock from the cartridge or cartridge compartment 205, or performing other cleaning of the cartridge or cartridge compartment 206.

[0091] Below the cover 220, vents 227 from the fan compartment and a sprayer 206 are visible. A filler cap 209 may be located adjacent to the sprayer. The filler cap 209 can be rotated or removed, allowing the user to add disinfectant fluid to the cartridge compartment 205 or the box 210.

[0092] like Figure 20C As shown, the cover 222 may also include at least one fin 226 configured to guide an airflow containing fine particles of disinfectant fluid toward the surface of the toilet seat 202.

[0093] Figure 21 An example disinfectant container 210 is illustrated. The container 210 may be oriented at different angles to the wick compartment 205. The container 210 stores disinfectant and is fluidly coupled to the wick compartment 205. The container 210 may be a cylindrical prism. The container 210 may be flexible (e.g., a bag). A wick and / or wick compartment 205 may mate with the container 210.

[0094] Dial 290 may be adjacent to wicking compartment 205. Dial 190 may be coupled to a rotary valve 291 with a through-hole or recess 269. When dial 290 is rotated, rotary valve 291 opens and closes. In one example, rotary valve 291 connects box 210 and wicking compartment 205 in a first position and disconnects box 210 and wicking compartment 205 in a second position. The connection between box 210 and wicking compartment 205 can have various configurations. In one example, a metering device may be present between box 210 and wicking compartment 206 to allow only a predetermined amount of disinfectant fluid to enter the wicking compartment. Since box 210 is typically more sealed or waterproof than the wicking compartment, most of the hydrogen peroxide can be retained in box 210.

[0095] In one example, the connection between the chamber 210 and the cartridge compartment 205 includes a one-way valve. The one-way valve prevents the disinfectant fluid from flowing back from the cartridge compartment 205 to the chamber 210. If water splashes into the cartridge compartment 206 or urine enters the cartridge compartment 202, it will not flow back and contaminate the chamber 210.

[0096] In one example, the connection between the housing 210 and the cartridge compartment 205 varies depending on the rotation of the cartridge. The cartridge compartment 205 may include an opening 269 that aligns with the opening of the housing 210 when the cartridge is rotated in the open position. Otherwise, in the closed position, the cartridge compartment 205 rotates, causing the opening to misalign. The cartridge can also be released by rotation, thereby cleaning the empty cartridge compartment 205.

[0097] The cartridge compartment 205 can also be discharged by rotation. For example, the bottom of the cartridge compartment 205 can be fitted with a valve 229, which includes a through hole 228 that is opened when the cartridge is rotated.

[0098] In addition to venting the suction chamber 205, liquid may sometimes be present in the toilet seat assembly 200 due to splashing. This can happen when a user adds disinfectant fluid to the toilet seat assembly 200, which may splash into the chamber. For example, a user may splash urine into the toilet seat assembly 200 while urinating. In these cases, the toilet seat assembly 200 is designed to drain the splashed liquid into the toilet bowl.

[0099] Figure 22 An example exhaust panel 275 is illustrated. The exhaust panel 275 may include a solid portion 211 and an opening 212. Figure 23 The illustration shows an example of a splash or overflow path through a toilet seat assembly. The overflow path includes multiple surfaces sloping towards the toilet bowl.

[0100] The splash path may span multiple surfaces. The splash path may include the base plate 271 of the disinfection compartment, the wall shelf 272 for supporting the suction compartment 205, the top surface 273 of the side compartment, and the vertical passage 274.

[0101] The discharge plate 275 can be tilted downward toward the toilet bowl (e.g., in the direction of gravity) so that any spillage moves away from the hinge structure and toward the toilet bowl. The hinge structure includes water-sensitive components such as controllers, power supplies, and various wiring.

[0102] Figure 24A and Figure 24B An example lock for a cartridge is illustrated. A spray cap 265 can be attached to the cartridge compartment 205 at the ridge 262 via a connector, and also to the sprayer 206 via a connector. Various locking protrusions 261 engage or disengage the spray cap 265 as it rotates along the ridge 262.

[0103] When one or more of the protrusions engage the spray cap 265 in a first position, it locks into the housing of the suction chamber 205 and the sprayer 206. The first position can be a relative rotational position between the spray cap 265 and the suction chamber 209. When one or more of the protrusions engage the spray cap 266 in a second position, the suction chamber 205 can be removed. The second position can also be a relative rotational position between the spray cap 265 and the suction chamber 205.

[0104] Figure 25A and Figure 25B An example fin 231 for disinfection airflow is illustrated. As the airflow in the hinged structure exits the disinfection compartment, it is released into the seat compartment, which overlaps with the toilet seat 100. Air is most effective as it travels around the toilet seat 100. Fin 231 provides a guiding airflow path around the toilet seat. Figure 282 illustrates the airflow path.

[0105] Figure 26 The illustration shows an example arrangement of fins 231 on a toilet seat 100. Fins 232 can be bent from the vent 227 and then are horizontal along the rear of the toilet seat 100.

[0106] Figure 27 Another view of the fin 231 integrated with one or more seals 104 and 106 is illustrated. That is, the integrated component of a single construction may include the fin 231, the seal 104, and the seal 106.

[0107] Figure 28The illustration shows a rear view of a toilet seat assembly including a slide switch 230. The slide switch 230 can be electrically connected to a controller. The slide switch 230 can operate various functions of the toilet seat assembly. Figure 29 An example position 232 of the slide switch 230 is illustrated. A stop (e.g., a rubber washer) in the flexible housing allows the switch 230 to move between positions 232 by flexing the flexible housing but easily stopping it in a recess within the flexible housing. The slide switch 230 can open and close the toilet seat assembly 200. The slide switch 230 may be spring-loaded to aid movement through the stop in the flexible housing. Additional, different, or fewer components may be included.

[0108] The slide switch 230 can be an example slider configured to select a mode of the toilet seat assembly. The mode controls how the toilet seat assembly 200 opens the ring or seat 100 and lid 101 using the motor 283. The toilet seat assembly 200 can have an on-premises-only opening mode, in which the controller sends a command to operate the motor 283 to open the lid 101 only when the presence of a user is detected. The toilet seat assembly 200 can have an automatic opening mode, in which the controller sends a command to operate the motor 283 after the cleaning cycle has ended. The controller can determine that the cleaning cycle has ended based on a timer reaching a set elapsed time. The controller can also determine that the cleaning cycle has ended based on data from a humidity sensor in the seat compartment.

[0109] A maintenance mode can exist where the controller checks the operation of sprayer 206, fan 207, or other components. In maintenance mode, the controller can check the level of the disinfectant fluid.

[0110] In one example, motor 283 is omitted, and a slow-closing damper is used. In this case, slide switch 230 can only turn the disinfection system on and off. Sprayer 206 can also be omitted, allowing the disinfectant fluid to evaporate directionally into the air. Fan 207 can also be omitted. Airflow can be achieved by the suction generated when flushing the toilet with lid 101 closed.

[0111] Various power supply devices can be used. The toilet seat assembly 200 may include wiring for obtaining AC power from a socket. The toilet seat assembly 200 may include an AC-to-DC (ADC) converter. Power is supplied from the power supply device to the sprayer 206, fan 207, motor 283, display, and other components. In some examples, batteries may be used. The batteries may be removable and rechargeable.

[0112] The display may include indicator lights for the operation of the toilet seat assembly 200, which will be discussed in more detail below.

[0113] Figure 30A and Figure 30B An example quick-release hinge 234 for a toilet seat assembly 200 is illustrated. The releasable hinge 233 is mounted using a frame 235 and biased outward by a spring 236 (biasing member). The releasable hinge 234 can be operated in a locked position, for example, by being pushed out by the spring 236. In the locked position, the toilet seat assembly 200 cannot be removed from the toilet. When the user presses the releasable hinge 234, which may require one or both hinges, the hinge 234 moves from the locked position to the unlocked position against the force of the spring 235. In the unlocked position, the toilet seat assembly 200 can be removed from the toilet.

[0114] In some examples, the releasable hinge 234 is operable in a further locked position or an over-locked position. This position can lock the releasable hinge 234 regardless of whether the releasable hinge 344 is pushed against the bias member 236. The over-lock can only be reversed using a special tool or key.

[0115] Figure 31 The illustration shows an example air path P2 that, as air passes through example air vent 227, is guided through the bottom of cover 222, causing the airflow to be arc-shaped relative to the horizontal direction. After the bottom of cover 222, the air passes through an arc-shaped feature 284 on the housing of toilet seat assembly 200, further directing the airflow downwards toward seat 102.

[0116] Figure 32 Another example of a toilet seat seal 240 is illustrated. The seal may have two parts. The first part extends between the seat ring 102 and the toilet bowl. The second part extends between the seat ring 102 and the lid 101. Each part includes its own curved members 241 and 242. The curved members 241 and 242 contribute to the seal as the seat ring 102 moves relative to the toilet bowl and the lid 101.

[0117] Figure 33 The illustration shows a ventilation space between the toilet seat 102 and the toilet lid 101. A seal 240 prevents a plume of air from the toilet bowl from escaping into the environment. The ventilation space includes three seals. Seals 244 and 245 define a sterilization space for the seat 102, to which atomized airflow is directed. Seal 240 may extend to the lid 101 and form a seal with it. Seal 240 may not span the entire gap between the lid 101 and the seat 102.

[0118] Figure 34 The illustration shows a display 401 for a toilet seat assembly 200. The display 401 may be located on a cover 220. The display 401 may be adjacent to the cover 220 on the lid of the toilet seat assembly 200. The display 401 may be located on a hinge portion.

[0119] Display 401 can convey various information to the user. In a simple example, display 401 includes a single indicator light that illuminates to indicate that the toilet seat assembly 200 is available for use. In another example, display 401 may include a countdown timer until the toilet seat assembly 200 is available for use (e.g., when the surface of the seat 100 is dry or expected to be dry). Example timers may include 30 seconds, 1 minute, and 5 minutes.

[0120] In another example, display 401 may include a lamp array or lamp matrix (e.g., an LED array or LED matrix). Figure 34 As shown, various images can be formed using a matrix of lights. The first image can indicate availability. The second image can indicate that cleaning is in progress. Another image can indicate that it is drying. Yet another image can indicate the time since the last cleaning. The images can be part of an animation or video. In another example, a circular indicator gives the status or progress bar of the cleaning process. The circular indicator can be illuminated by several LEDs arranged in a ring.

[0121] Display 401 may include an indicator of the level of disinfectant fluid in tank 210. Display 401 may instruct the user to refill tank 210. Display 401 may include indicators of energy usage, battery life, or other electrical parameters. Display 401 may indicate the mode. Display 401 may indicate which devices are operating (e.g., fan 207, sprayer 209, etc.).

[0122] Figure 35 A controller 40 for a toilet seat assembly is illustrated. The controller 40 may include a processor 310, a memory 352, and a communication interface 353 for interfacing with a device or the Internet and / or other networks 346.

Components of the control system 40 may communicate using a bus 348. The control system 40 may be connected to a workstation or another external device (e.g., a control panel) and / or a database to receive user input, system characteristics, and any values ​​described herein.

[0123] Optionally, the control system 40 may include an input device 355 and / or sensing circuitry that communicates with any sensor. The sensing circuitry receives sensor measurements from the aforementioned sensors. The input device 355 may include a switch, button, flush lever, touchscreen, keyboard, microphone for voice input, camera for gesture input, and / or other mechanisms.

[0124] Optionally, the control system 40 may include a drive unit 340 for receiving and reading non-transitory computer media 341 having instructions 342. Additional, different, or fewer components may be included. The processor 310 is configured to execute instructions 342 stored in memory 352 to perform the algorithms described herein. The display 350 may be combined with a user input device 355.

[0125] Figure 36 The diagram shows... Figure 35 The flowchart 1050 for the controller may include additional, different, or fewer actions. In action S101, the controller 40 (e.g., via processor 310) receives usage information related to the toilet bowl. Usage information may be from a user pressing a button. Usage information may be detected by a flush cycle. Usage information may be detected by movement of the toilet seat 100 or lid 101.

[0126] In action S103, the controller 40 causes the toilet seat assembly to perform an atomization operation. The atomization operation generates a disinfecting fluid. In action S105, the controller 40 performs a dispensing operation at the toilet seat assembly. The dispensing operation can be triggered by fan operation or by the opening of a valve.

[0127] Figure 37 The diagram shows... Figure 35 The flowchart for the controller is 1060. It may include additional, different, or fewer actions.

[0128] In action S201, controller 40 supplies current to the fan used in the disinfectant path or causes the power supply to supply current to the fan used in the disinfectant path. The fan can operate as part of the cleaning sequence. The fan can operate at all stages of the cleaning sequence.

[0129] The cleaning sequence can be triggered by a variety of technologies. The cleaning sequence can begin with a flushing sequence. Controller 40 can determine that a flushing sequence has started based on signals from the electronic flush lever. Controller 40 can also determine that a flushing sequence has started based on sensor data (such as data from a flow sensor, tank level sensor, toilet bowl sensor, or another sensor). The cleaning sequence can also be started via a button on the toilet seat assembly 200 or other inputs.

[0130] In action S203, controller 40 supplies current to the sprayer or causes the power supply device to supply current to the sprayer, which then sprays disinfectant in the disinfectant path. In some examples, the sprayer operates after the fan has started operating and the airflow has circulated for a certain period of time. In other examples, the sprayer can operate at all stages of the cleaning sequence. The disinfectant path can be opened in response to the opening of the toilet seat assembly lid.

[0131] In action S205, controller 40 starts a timer for the cleaning process. The timer can be a predetermined amount of time selected for the cleaning sequence. The timer can be used to turn off the fan and sprayer at specific times. When the time reaches a first threshold, controller 40 can turn off the sprayer. When the time reaches a second threshold, controller 40 can turn off the fan.

[0132] In action S207, controller 40 enables lid operation after the final cleaning sequence threshold has passed on the timer. Enabling the lid may include operating the motor to open the lid. Enabling the lid may mean unlocking the lid, allowing the user to press a button to open the lid or manually grasp and open the lid. The following steps involve the automatic opening of the lid.

[0133] In action S209, controller 40 receives sensor data from the user. The sensor data may indicate that the user has approached the toilet or has made a gesture to open the lid. The sensor data can be generated at the proximity sensor. In action S211, controller 40 operates the lid by supplying current to the motor in response to the sensor data.
