Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Patent Application Ser. No. 62/958,570, entitled “WATER EFFICIENT TOILET SYSTEM,” filed Jan. 8, 2020. The contents of this application are hereby incorporated by reference in their entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     Water is considered potentially to be one of the most scarce resources going forward. Extreme droughts and shifting weather patterns have led to severe economic and health concerns. Rationing of water supplies is common in many countries due to increasing demand in densely populated urban areas. Further, water treatment technologies such as water desalination processes are not yet economically efficient enough at the scale demanded by worldwide water usage. Therefore, it is desired to reduce water usage where possible, such as in common everyday appliances like toilets. Advances in water reduction capacities for such appliances would be welcomed in any water scarce market and would provide economic advantage to related users. 
     It would be advantageous to provide a toilet that reduces water consumption by providing a user of the toilet the ability to flush the toilet with minimal or no water. Further, it would be advantageous to provide a toilet with a multi-basin interior to allow the user to choose which basin to utilize in order to reduce water consumption. Additionally, it would be advantageous to provide a flushing system that allows the user to independently flush one or both of the multi-basin interior using a liquid or non-liquid fluid. Further, it would be advantageous to provide a toilet with a flushing system that may be operated via voice, motion or touch in order to provide a more sanitary experience. 
     Additionally, it would be advantageous to provide a toilet having a rim that allows for liquid and/or gaseous flushing while at least in part using the same liquid and/or gas to further cleanse and/or dry the user during and after use of the toilet, thereby further conserving water and providing a more sanitary user experience. Further, it would be advantageous to provide a fluid-tight seal between the toilet rim, seat and lid, thereby preventing any noxious odors from escaping either of the basis of the multi-basin toilet interior and providing the user a more pleasant and sanitary experience.

However, it will also be apparent that the techniques described below may be practiced in different configurations without the specific details. Furthermore, well-known features may be omitted or simplified to avoid obscuring the techniques being described. 
     Exemplary embodiments of the present invention are illustrated in the accompanying figures. As shown in  FIG. 1 , an overhead view of a water efficient toilet system  100  is portrayed. The system  100  generally comprises a first toilet basin  110  and a second toilet basin  120  separated by a divider  130 . The first toilet basin  110  and the second toilet basin  120  are disposed within a toilet rim  140 . The toilet rim  140  supports a toilet seat  150  which itself supports a toilet lid  160 . Further, a storage tank  170  is coupled to a rear portion of the toilet rim  140 . 
     Further, the first toilet basin  110  comprises a first drain conduit opening  112  disposed substantially within the center of the first basin  110 . The first drain conduit opening  112  allows for flushing liquid (not shown) within the first basin  110  to flush any contents therein down into a first drain conduit coupled with the opening  112 . The second toilet basin  120  comprises a second drain conduit opening  122  disposed substantially within the center of the second basin  120 . The second drain conduit opening  122  allows for flushing liquid (not shown) within the second basin  120  to flush any contents therein down into a second drain conduit coupled with the opening  122 . Alternatively, the second toilet basin  120  may operate dry without the use of any flushing liquid. 
     Additionally, the first toilet basin  110  may have a larger dimensional surface area than the second toilet basin  120  in order to allow a user to align relevant body parts with each basin when sitting upon the seat  150 . Specifically, using the  FIG. 1  overhead view as reference, the first toilet basin  110  may have a front-to-back length dimension substantially between 1.25-2.5 times the front-to-back length dimension of the second toilet basin  120 , but preferably between 1.25-2 times the front-to-back length dimension of the second toilet basin  120 , and more preferably between 1.25-1.75 times the front-to-back length dimension of the second toilet basin  120 . 
     The front-to-back length dimension of the first toilet basin  110  may be measured from a rear of the toilet rim  140  to the divider  130 . The front-to-back length dimension of the second toilet basin  120  may be measured from a front of the toilet rim  140  to the divider  130 . Further, the front-to-back length dimension of each of the first toilet basin  110  and the second toilet basin  120  may be measured using an averaged length value between the toilet rim  140  and the divider  130  for respective first toilet basin  110  measurements and second toilet basin  120  measurements. 
     Similarly, the first toilet basin  110  may have a side-to-side width dimension substantially between 1-1.5 times the side-to-side width dimension of the second toilet basin  120 , but preferably between 1.1-1.4 times the side-to-side width dimension of the second toilet basin  120 , and more preferably between 1.15-1.35 times the side-to-side width dimension of the second toilet basin  120 . 
     The side-to-side width dimension of the first toilet basin  110  may be measured from a first side of the toilet rim  140  within the first toilet basin  110  region to a second side of the toilet rim  140  within the first toilet basin  110  region. The side-to-side width dimension of the second toilet basin  120  may be measured from the first side of the toilet rim  140  within the second toilet basin  120  region to the second side of the toilet rim within the second toilet basin region. Further, the side-to-side width dimension of each of the first toilet basin  110  and the second toilet basin  120  may be measured using an averaged width value between the first and second sides of the toilet rim  140  within respective first and second toilet basin  110 ,  120  regions. 
     Additionally, the toilet rim  140  structurally supports and is disposed adjacent to the toilet seat  150 . The toilet seat  150  may be structured to accommodate the shape of the toilet rim  140  and associated first and second toilet basins  110 ,  120 . Further, the toilet seat  150  may be structurally coupled to the toilet lid  160 . Each of the toilet seat  150  and toilet lid  160  may be rotationally coupled to the rear of the toilet rim  140  such that the seat  150  and lid  160  may be rotated between a first position adjacent the rim  140  and a second position adjacent the storage tank  170 . 
     Moreover, when the seat  150  and lid  160  are arranged in the first position, the rim  140 , seat  150  and lid  160  may form a fluid seal to contain any odors remaining within the cavity of the first and second basins  110 ,  120 . One or both of the top and bottom sides of the seat  150  and lid  160  may comprise fluid-sealing material including, but not limited to, polymer material, structural metal (e.g., structural steel or structural aluminum), co-polymer material, thermoplastic and thermosetting polymers, resin-containing material, polyethylene, polystyrene, polypropylene, epoxy resins, phenolic resins, Acrylanitrile Butadiene Styrene (ABS), Polycarbonate (PC), Mix of ABS and PC, Acetal (POM), Acetate, Acrylic (PMMA), Liquid Crystal Polymer (LCP), Mylar, Polyamid-Nylon, Polyamid-Nylon 6, Polyamid-Nylon 11, Polybutylene Terephthalate (PBT), Polycarbonate (PC), Polyetherimide (PEI), Polyethylene (PE), Low Density PE (LDPE), High Density PE (HDPE), Ultra High Molecular Weight PE (UHMW PE), Polyethylene Terephthalate (PET), PolPolypropylene (PP), Polyphthalamide (PPA), Polyphenylene sulfide (PPS), Polystyrene (PS), High Impact Polystyrene (HIPS), Polysulfone (PSU), Polyurethane (PU), Polyvinyl Chloride (PVC), Chlorinated Polyvinyl chloride (CPVC), Polyvinylidenefluoride (PVDF), Styrene Acrylonitrile (SAN), Teflon TFE, Thermoplastic Elastomer (TPE), Thermoplastic Polyurethane (TPU), and/or Engineered Thermoplastic Polyurethane (ETPU) or other similar materials and any combinations thereof. 
     Further, while the toilet seat  150  and toilet lid  160  are in the first position sealing fluid within the first toilet basin  110  and second toilet basin  120 , odor-eliminating materials may be directed into the first toilet basin  110  and second toilet basin  120 . Such odor-eliminating materials may include, but are not limited to, ozone, essential oils, synthetic fragrances, disinfectants or other similar materials and any combinations thereof. In the example of ozone being utilized, an ozone generator may be disposed within the storage tank  170 , shown in  FIG. 5 , to pass ozone through one or conduits into the cavity defined by the first toilet basin  110 , the second toilet basin  120 , the toilet seat and the toilet lid  160 . Other exemplary odor-eliminating materials may be introduced into the cavity in a similar means. 
     The storage tank  170  may be structurally coupled to the rear of the toilet rim  140  and a toilet underbody (not shown) while supporting the toilet seat  150  and toilet lid  160  when each are placed into the second position. The storage tank  170  may function substantially according to prior art toilet storage tanks by storing flushing liquid to be dispersed into the toilet basin upon a user flushing the toilet. Specifically, the storage tank  170  may supply flushing liquid to the first toilet basin  110  and/or the second toilet basin  120  based upon the type of user selection of a flushing actuation mechanism explained in more detail in  FIGS. 3 &amp; 5 . 
     Specifically, the particular user selection of the flushing actuation mechanism may be based upon the type of excrement contained within the first toilet basin  110  and/or the second toilet basin  120 . If semi-solid or solid excrement is contained within the first toilet basin  110  and/or the second toilet basin  120 , then a first type of user selection of the flushing mechanism may be selected. If liquid excrement is contained within the first toilet basin  110  and/or the second toilet basin  120 , then a second type of user selection of the flushing mechanism may be selected. Alternatively, the first and second types of user selection of the flushing mechanisms may determine whether the first toilet basin  110  and/or the second toilet basin  120  is flushed using the flushing liquid contained in the storage tank  170 . 
     As shown in  FIG. 2 , a cross-sectional view of a toilet basin  200  of a water efficient toilet system is portrayed. The toilet basin  200  may comprise a first toilet basin  210  and a second toilet basin  220  separated by a divider  230 .

Specifically, the first toilet basin  210  may have a front-to-back length dimension substantially between 1.25-2.5 times the front-to-back length dimension of the second toilet basin  220 , but preferably between 1.25-2 times the front-to-back length dimension of the second toilet basin  220 , and more preferably between 1.25-1.75 times the front-to-back length dimension of the second toilet basin  220 . 
     The front-to-back length dimension of the first toilet basin  210  may be measured from a rear of the toilet rim  240  to the divider  230 . The front-to-back length dimension of the second toilet basin  220  may be measured from a front of the toilet rim  240  to the divider  230 . Further, the front-to-back length dimension of each of the first toilet basin  210  and the second toilet basin  220  may be measured using an averaged length value between the toilet rim  240  and the divider  230  for respective first toilet basin  210  measurements and second toilet basin  220  measurements. 
     Similarly, the first toilet basin  210  may have a side-to-side width dimension substantially between 1-1.5 times the side-to-side width dimension of the second toilet basin  220 , but preferably between 1.1-1.4 times the side-to-side width dimension of the second toilet basin  220 , and more preferably between 1.15-1.35 times the side-to-side width dimension of the second toilet basin  220 . 
     The side-to-side width dimension of the first toilet basin  210  may be measured from a first side of the toilet rim  240  within the first toilet basin  210  region to a second side of the toilet rim  240  within the first toilet basin  210  region. The side-to-side width dimension of the second toilet basin  220  may be measured from the first side of the toilet rim  240  within the second toilet basin  220  region to the second side of the toilet rim within the second toilet basin region. Further, the side-to-side width dimension of each of the first toilet basin  210  and the second toilet basin  220  may be measured using an averaged width value between the first and second sides of the toilet rim  240  within respective first and second toilet basin  210 ,  220  regions. 
     While the plurality of fluid-flow apertures  242  are shown to be substantially rectangular in  FIG. 2 , the apertures  242  may be sized and shaped in any suitable manner. Specifically, the length and width dimensions of the fluid-flow apertures  242  may be between 1-8 centimeters, but preferably between 2-6 centimeters, and more preferably between 3-4 centimeters. Further, the shape of the fluid-flow apertures  242  may include, but are not limited to, rectangular, circular, elliptical, triangular and similar shapes or combinations thereof. 
     The fluid-flow apertures  242  may pass one or more types of fluid therethrough to portions of the user that are disposed within the toilet rim  240 . The one or more types of fluid may include, but are not limited to, environmental air, oxygenated air, pure ozone, water, essential oils, synthetic fragrances, sanitizing solutions, disinfecting solutions, cleaning solutions, non-toxic solutions and similar materials or any combinations thereof. Further, an air compressor (further detailed in  FIG. 5 ) contained within the storage tank may be utilized to compress the one or more fluids and expel those compressed fluids through the apertures  242  via the conduit  246  and/or one or more sub-conduits contained within the conduit  246 . The one or more compressed fluids may be utilized to clean portions of the user that are disposed within the toilet rim  240 . Further, the one or more compressed fluids may be utilized to dry portions of the user that are disposed within the toilet rim  240  after those same portions of the user within the toilet rim  240  have been cleaned. 
     While the plurality of liquid-flow apertures  244  of each of the first toilet basin  210  and second toilet basin  220  are shown to be substantially circular in  FIG. 2 , the apertures  244  may be sized and shaped in any suitable manner.

Further, the shape of the liquid-flow apertures  244  may include, but are not limited to, rectangular, circular, elliptical, triangular and similar shapes or combinations thereof. 
     The liquid-flow apertures  244  may pass one or more types of liquid there through to one or both of the first toilet basin  210  and second toilet basin  220 . The one or more types of liquid may include, but are not limited to, water, ozonated water, essential oils, synthetic fragrances, sanitizing solutions, disinfecting solutions, cleaning solutions and similar materials or any combinations thereof. A first set of liquid-flow apertures  244   a  associated with the first toilet basin  210  may be operated independently of a second set of liquid flow apertures  244   b  associated with the second toilet basin  220 . A particular user selection of the flushing actuation mechanism determines whether the first set of liquid-flow apertures  244   a  and/or the second set of liquid-flow apertures  244   b  are utilized. 
     Specifically, the particular user selection of the flushing actuation mechanism may be based upon the type of excrement contained within the first toilet basin  210  and/or the second toilet basin  220 . If semi-solid or solid excrement is contained within the first toilet basin  210  and/or the second toilet basin  220 , then a first type of user selection of the flushing mechanism may be selected. If liquid excrement is contained within the first toilet basin  210  and/or the second toilet basin  220 , then a second type of user selection of the flushing mechanism may be selected. Alternatively, the first and second types of user selection of the flushing mechanisms may determine whether the first toilet basin  210  and/or the second toilet basin  220  is flushed using the flushing liquid contained in the storage tank. 
     Further, an electronic controller (further detailed in  FIG. 5 ) may further control the operation of the first set of liquid-flow apertures  244   a  and the second set of liquid-flow apertures  244   b . Specifically, the electronic controller may operate in conjunction with the flushing mechanism to execute the functionality associated with the particular user selection of the flushing mechanism.

Specifically, the storage tank  370  may supply flushing liquid to the toilet basin  330  upon user selection of a flushing actuation mechanism  374 . Further, a tank lid  372  is disposed upon a top portion of the storage tank  370  allowing the user to selectively remove the tank lid  372  to permit the user access to the interior of the storage tank  370  for maintenance and like activities. 
     While the flushing mechanism  374  is shown in  FIG. 3  to be a traditional manually-levered handle flushing mechanism, any suitable style of flushing mechanism  374  may be utilized including, but not limited to, flushing mechanisms operated via mechanical, pneumatic, hydraulic, manual and similar means or any combination thereof. Specifically, the flushing mechanism  374  may be actuated via voice activation, motion activation, touch activation and similar means or any combinations thereof. The electromechanical functionality associated with the voice activation, motion activation, touch activation, proximity activation etc. may in part be executed by an electronic controller (further detailed in  FIG. 5 ) contained within the storage tank  370 . Further, the flushing mechanism  374  may be at least in part located external or internal to the toilet basin  330 , the toilet rim  340 , the toilet seat  350 , the toilet lid  360 , the storage tank  370  and/or the tank lid  372 . 
     As shown in  FIG. 4 , a cross-sectional view of a portion of a water efficient toilet system  400  is portrayed. The system  400  generally comprises a first drain conduit  410  and a second drain conduit  420  each terminating at a common drain terminal  412 . Further, the second drain conduit  420  comprises a u-shaped p-trap  422  between the terminal ends of the second drain conduit  420 . A divider  430  is coupled to a toilet rim  440  and divides two portions of a toilet basin disposed within the toilet rim  440 . The toilet rim  440  comprises a plurality of fluid-flow apertures  442 , a plurality of liquid-flow apertures  444  and a conduit  446 . 
     The liquid-flow apertures  444  may be separated by the divider  430  into a first set of liquid-flow apertures  444   a  and a second set of liquid-flow apertures  444   b . Further, a storage tank terminal conduit  460  may be disposed at a rear portion of the toilet rim  440  and may couple directly to the toilet rim conduit  446  which itself terminates at the plurality of fluid-flow apertures  442  and the plurality of liquid-flow apertures  444 . Additionally, a front underbody portion of the water efficient toilet system  400  may comprise a removable plate  450  in order to allow a user access to the interior of the front underbody portion for purposes of routine maintenance by a professional. 
     As shown in  FIG. 5 , a detailed view of a storage tank  500  of a water efficient toilet system is portrayed. The storage tank  500  generally comprises an exterior body  510 , a tank lid  512 , a flushing mechanism  514 , a storage tank terminal conduit  520  and tank plumbing  530 . The exterior body  510  defines a cavity therein that may be filled with flushing fluid to be flushed out of the cavity via the storage tank terminal conduit  520  upon actuation of the flushing mechanism  514  and operation of the tank plumbing  530 . The tank plumbing  530  may operate substantially as prior art tank plumbing. Alternatively, the tank plumbing  530  may operate according to the type of flushing mechanism  514  chosen. 
     For example, while the flushing mechanism  514  is shown in  FIG. 5  to be a traditional manually-levered handle flushing mechanism, any suitable style of flushing mechanism  514  may be utilized including, but not limited to, flushing mechanisms operated via mechanical, pneumatic, hydraulic, manual and similar means or any combination thereof. Specifically, the flushing mechanism  514  may be actuated via voice activation, motion activation, touch activation and similar means or any combinations thereof. The electromechanical functionality associated with the voice activation, motion activation, touch activation etc. may in part be executed by an electronic controller  550  contained within the storage tank  500 . Further, the flushing mechanism  514  may be at least in part located external or internal to the toilet basin  330  of  FIG. 3 , the toilet rim  340  of  FIG. 3 , the toilet seat  350  of  FIG. 3 , the toilet lid  360  of  FIG. 3 , the storage tank  500  and/or the tank lid  512 . 
     Further, the storage tank  500  may comprise an air compressor  540  for compressing one or more fluids to be passed through one or more conduits (not shown) to the storage tank terminal conduit  520  and to the apertures  442 ,  444  via conduit  446  as shown in  FIG. 4 . The air compressor  540  may cooperate with the electronic controller  550  to operate in conjunction with the flushing mechanism  514  or similar means. 
     Similarly, the storage tank  500  may comprise an ozone generator  560  for generating fluid ozone to be passed through one or more conduits (not shown) to the storage tank terminal conduit  520  and to the apertures  442 ,  444  via conduits  446  as shown in  FIG. 4 . The ozone generator  560  may cooperate with the electronic controller  550  to operate in conjunction with the flushing mechanism  514  or similar means. Alternatively, the ozone generator  560  may cooperate with eh electronic controller  550  to operate according to a preprogrammed iterative schedule for ozonating the interior of the toilet basin at regular intervals. Ozonation of the toilet basin interior allows for a decrease in noxious odors emanating from the toilet basin and further may disinfect the fluid contents and surfaces therein. 
     For example, the electronic controller  550  may operate in conjunction with the toilet seat  350  of  FIG. 3  and toilet lid  360  of  FIG. 3  to detect a fluid seal being formed around the interior of the toilet basin  330  of  FIG. 3 . Such detection may be accomplished via one or more proximity or rotation sensors disposed upon and/or within the toilet basin  330  of  FIG. 3 , the toilet rim  340  of  FIG. 3 , the toilet seat  350  of  FIG. 3 , the toilet lid  360  of  FIG. 3  and/or the exterior body  514 . Proximity sensing may be accomplished via one or more of capacitive sensors, photodetectors, weight sensors, pressure sensors and similar sensing devices or any combinations thereof. Rotational detection may be accomplished via the rotational positioning of the toilet seat  350  and toilet lid  360  between the first and second positions between toilet rim  340  and storage tank exterior body  514  as described with reference to  FIG. 3 . Such rotational detection may be captured via one or more of optical encoders, incremental encoders, absolute encoders, magnetic sensors, Hall-effect sensors, variable-reluctance sensors, eddy-current killed oscillators, Wiegand sensors, gear tooth sensors and similar sensing devices or any combinations thereof. The aforementioned proximity and rotational sensors may be utilized in conjunction with any other electronic component described in any of the aforementioned  FIGS. 1-5 , but particularly with respect to the flushing mechanism of  FIG. 3  and the other electrical components illustrated in  FIG. 5 . 
     The specification and drawings are to be regarded in an illustrative rather than a restrictive sense. However, it will be evident that various modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the claims. Other variations are within the spirit of the present disclosure. Thus, while the disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in the drawings and have been described above in detail. It should be understood, however, that there is no intention to limit the invention to the specific form or forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention, as defined in the appended claims. 
     The use of the terms “a,” “an,” “the,” and similar referents in the context of describing the disclosed embodiments (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. The term “connected,” where unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated and each separate value is incorporated into the specification as if it were individually recited. The use of the term “set” (e.g., “a set of items”) or “subset” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, the term “subset” of a corresponding set does not necessarily denote a proper subset of the corresponding set, but the subset and the corresponding set may be equal. 
     Conjunctive language, such as phrases of the form “at least one of A, B, and C,” or “at least one of A, B and C,” is understood with the context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of the set of A and B and C, unless specifically stated otherwise or otherwise clearly contradicted by context. For instance, in the illustrative example of a set having three members, the conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of the following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, the term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). The number of items in a plurality is at least two, but can be more when so indicated either explicitly or by context. 
     The use of any examples, or exemplary language (e.g., “such as”) provided, is intended merely to better illuminate embodiments of the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention. 
     Embodiments of this disclosure are described, including the best mode known to the inventors for carrying out the invention. Variations of those embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate and the inventors intend for embodiments of the present disclosure to be practiced otherwise than as specifically described. Accordingly, the scope of the present disclosure includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, although above-described elements may be described in the context of certain embodiments of the specification, unless stated otherwise or otherwise clear from context, these elements are not mutually exclusive to only those embodiments in which they are described; any combination of the above-described elements in all possible variations thereof is encompassed by the scope of the present disclosure unless otherwise indicated or otherwise clearly contradicted by context. 
     All references, including publications, patent applications, and patents, cited are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety.
