Description

A TOILET SANITARY SYSTEM

Field of the Invention

The present invention relates to the field of sanitary equipment. More particularly, the invention relates to a toilet sanitary system for performing automated sanitary operations such as dispensing aerosol and other sanitation substances following a toilet being flushed.

Background of the Invention

Toilets are used on a routine daily basis of life. Due to the manner in which they are used there is need in frequent cleansing and disinfecting of toilets. Neglecting a toilet could lead to a hygienic danger, in addition to damaging the toilet itself. Toilets may be cleaned manually, however this is a time and man-power consuming solution, besides being a generally unpleasant operation to perform.

A common solution includes a detergent (by using the term "detergent" it is meant to include also disinfectant substances) containing tab hung on the rim of the toilet bowl that directly interacts with the water when flushed. This solution is imperfect because the total amount of water flushed does not evenly contain detergent, and therefore some areas of the toilet bowl may remain un-deterged.

Another solution includes adding detergent to the toilet tank, where the flushing water is accumulated before flushing. The detergent is commonly in the formation of tablets that comprise highly concentrated detergent that dissolves gradually into the water. This solution too is imperfect due to the need to periodically insert a new tablet as result of a previous tablet dissolving entirely.

Besides being time and man-power consuming, one is not always aware of the condition of a tablet inside the tank and might therefore not replace a dissolved tablet on time. Furthermore, it takes some time for a tablet to effectively dissolve in water, and consecutive flushing may result in a serving of water containing a low rate of detergent. In addition in some cases a tablet is capable of being flushed into the toilet bowl with the water, which besides wasting a tablet may cause a plumbing blockage.

Another need resulting from the common use of toilets is neutralizing undesirable odors. Common solutions in which are used for long epochs are manual and automated air fresheners, yet while manual air freshener is an additional publicly used toilet element which must be periodically cleaned and toilet users not always remember to use it, automated air fresheners requires refills and batteries replacement, and hence, becomes burdensome maintenance requiring element, in addition to its higher initial and running costs.

It is therefore an object of the present invention to provide a toilet sanitary system for automatically adding detergent to water inside a toilet water tank, wherein the detergent is mixed with the water with the flushing and that does not cause danger of blockage, independently of users' operation.

It is another object of the present invention to provide a toilet sanitary system for automatically dispensing air scenting substance for neutralizing undesirable odors.

It is yet another object of the present invention to provide a toilet sanitary system which is integrated into the toilet tank, thus requiring minimal space and minimal routine maintenance.

Other objects and advantages of the invention will become apparent as the description proceeds.

Detailed Description of the Invention

Reference will now be made to an embodiment of the present invention, examples of which are provided in the accompanying figures for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods exemplified herein may be employed, mutatis mutandis, without departing from the principles of the invention.

Fig. 1A schematically illustrates a section view of a toilet sanitary system during a suction operation, according to an embodiment of the present invention, in which a system 100 is comprised of a Venturi element 110, a cylindrical accumulation cell

120, a substance (e.g., detergent) receptacle 130, a suction tube 140, a dispensing tube 150 and unidirectional valves 141 and 151. The flow of water from the upstream utility piping side 111 through the narrowing-expending Venturi element 110, to the water consumer (e.g., toilet tank) side 115, being enabled by a downstream valve 160 (e.g., operated by a common manual toilet handle, or by an automated presence sensitive actuation), induces a low pressure in a side channel 113 and therethrough a low pressure above the actuating piston 121, thus together with the extension force of spring 122, pulls piston 121 upwards. The rising piston 121 induces low pressure bellow piston 121, thus enabling suction of desired substance from receptacle 130, through suction tube 140 and valve 141 into the low pressured cavity bellow piston 121. Furthermore, with low pressure bellow piston

121, valve 151 disallows incoming flow from tube 150.

The directional arrows in Fig. 1A are used to indicate flow direction of water and substance during the described suction operation. Also shown in Fig. 1A are the attachment measures 112 and 114, used for the integration of the proposed system with standard sanitation systems.

Fig. IB schematically illustrates a section view of a toilet sanitary system during a dispensing operation, according to an embodiment of the present invention, in which valve 160 is shutoff (e.g., by a common toilet buoy arrangement), disabling water flow through Venturi element 110 to the water consumer (e.g., toilet tank) side 115 (Fig. 1A), resulting with increased pressure in channel 113 and above piston 121 pushing it downwards, thus increasing pressure below piston 121. The increased pressure bellow the descending piston 121 enables the flow of accumulated substance (during the described suction operation in Fig. 1A) through valve 151 and tube 150. Furthermore, with increased pressure bellow the descending piston 121, valve 141 disallows the incoming flow from tube 140. Piston 121 may be a double sided piston, as shown in Fig. 3 below.

The abovementioned spring 122 of Figs. 1A and IB may not be required where water utility pressures are sufficient for creating the required Venturi effect for the proper suction and dispensing by system 100. Furthermore, different springs of different sizes and spring coefficients can be used in lieu of spring 122 in accordance with different conditions (i.e., utility conditions, type of Venturi element 110 and type of downstream water consumer) in various embodiments of the proposed system.

A skilled person can see the wide variety of embodiments, derived from the described mode of operation of the proposed system, yet further figures are added to describe embodiments of the present invention in which the proposed system is utilized to actuate independent sanitation equipment (e.g., the proposed system is adapted with mechanical arm to operate independent sanitation ancillaries), thus providing highly efficient and hygienic sanitation.

Fig. 2 schematically illustrates a section view of a toilet sanitary system during a dispensing operation, according to an embodiment of the present invention, in which system 200 comprises a separate actuation element 220, cylindrical accumulation cell 230 and a substance receptacle 270, where an auxiliary pressure transmission tube 213 is connected between channel 113 and actuation element 220, enabling a distributed installation of system 200.

Cylindrical accumulation cell 230 comprises a piston 231 which is installed on a piston rod 232 with an embedded suction/dispensing tube 240, wherein piston 221 touches piston rod 232. During a dispensing operation of the invented system 200 valve 260 is closed and the pressure in channel 113, tube 213 and above piston 221 increases pushing it downwards, thus pushing it downwards together with piston rod 232 and piston 231, resulting with substance (accumulated during the opposite suction operation into cylindrical accumulation cell 230) forced to flow through suction orifice 233 into embedded tube 240 within decreasing piston rod 232. A suitably sized ball 234 is utilized as a unidirectional valve to prevent said substance from returning to the substance receptacle 270. Element 250 illustrates a simple mechanical support (e.g., solid bracket) holding element 220 and cylindrical accumulation cell 230 in a fixed related position.

Fig. 3 schematically illustrates a section view of another embodiment of the proposed system, in which the proposed sanitary system is utilized for a parallel dispensing of toilet detergent and air scenting, wherein a Venturi element 310 and the actuating element 320 are installed in the two distal sides of a standard toilet tank 330 requiring no modification to the standard toilet system and allowing an external hygiene monitoring and replacement of water detergent refill 340 and air scenting refill 350, which are easily threaded onto a suction/dispensing element hub

330.

Figs. 4A-4B schematically illustrate other embodiments of the proposed sanitary system, in which an independent piston 80 is used for pumping the solution. After flushing ends, an upper piston is pushed by a spring 84. When moving upwardly, piston 80 allows a tubular rod 82 ending with a bended pipe 83, to be pushed by spring 87, to push independent piston 80 up and thereby pump solution from receptacle 85, to fill cylinder 86. Optionally, spring 84 may be omitted, in order to allow spring 87 to push rod 82, pipe 83 and piston 81 upwardly. Whenever the toilet is flushed, due to the generated Venturi sub-pressure, piston 81 moves down and pushes rod 82 and pipe 83 down, in order to open valve and allow discharge of the pumped solution via pipe 83, as a result from pushing independent piston 80 by conical flange 89.

Fig. 4B shows another embodiment, in which piston 81 and piston rod 83 are being integrated to a unified piston rod 82a and through which substance is being discharged, where piston rod 82a is being activated by Venturi pipe 213 similarly to piston 81 of Fig. 4A.

Fig. 5B schematically illustrates another embodiment of the proposed sanitary system, in which substance is pumped out from receptacles 85a and 85b, during emptying the main water tank 90 following flushing. In this embodiment, a venturi pipe 91 reduces the pressure in the upper cylinder 92 and pumping begins from receptacles 85a-85b by two independent pistons 80a-80b, similar to the operation of independent piston 80 of Fig. 4 above. In this example, receptacle 85a contains detergant solution and 85b contains odor extract. When flushing begins, the water level drops and causes buoy 93 to move downwardly, while opening inlet 94, to thereby allow water to flow from the Venturi element (e.g., element 310 of Fig. 3) into main water tank 90. As a result, venture pipe 213 starts pumping and piston 81 moves upwardly, to start pumping, as shown in Fig. 4.

When the water level escalates as a result of refilling main water tank 90, buoy 93 moves upwardly, while closing inlet 94, to complete the pumping-discharge cycle.

Fig. 5A schematically illustrates a cutaway view of a toilet sanitary system 500 for dispensing substance such as liquid detergent to be mixed with flushing water, according to another embodiment of the present invention, comprising a receptacle 501, a cylindrical accumulation cell 502 and a first pipe 503 for conveying substance from receptacle 501 to accumulation cell 502. A second pipe 504, accommodated within actuator 508, conveys substance from cell 502 out of the system 500. A piston 505 is provided within cell 502 and is configured to slide therethrough so as to pump substance in and out of thereof through pipes 503 and 504, respectively. A spring 506 is provided between ledges 510 and piston 505 exerting pressure on the bottom of the later and forcing the piston upwards. A spherical blocking apparatus 507 is provided for blocking transition of substance between receptacle 501 and cell 502. In this state, passages 511 are open to allow substance to flow into pipe 504.

The configuration of system 500 as shown in Fig. 5B may be obtained by actuator 508 being brought from a released position, in which piston 505 engages ledges 509 and spring 506 is extended and relaxed, to an actuated configuration in which piston 505 is forced through cell 502 and spring 506 is compressed.

Fig. 5C shows system 500 in another configuration where actuator 508 is released, allowing spring 506 to extend. When actuator 508 is released from its actuated position, spring 506 extends and causes piston 505 to slide proximally through cell 502 which creates vacuum inside accumulation cell 502. The vacuum causes blocking apparatus 507 to recede from opening 503a of pipe 503, and therefor allows substance to be pumped into cell 502 due to the vacuum. The proximal movement of piston 505 is limited by ledges 509.

Distal movement of piston 505 through cell 502 (due to actuation of actuator 508) causes high pressure in the cell. Consequently, blocking apparatus 507 is forced upon the opening 503a of pipe 503 preventing substance from passing through to the receptacle 501. Furthermore distal actuation (illustrated as downwards in Fig. 5B) of piston 505 reveals passages 511, through which substance may be transmitted from cell 502 to pipe 504 due to pressure inside cell 502.

Fig. 5D schematically illustrates opening 503a of pipe 503 from the shown from the inside of cell 502, according to an embodiment of the present invention, in which ledges 510 extend radially preventing passage of the blocking apparatus 507 into cell 502 while allowing passage of substance through gaps therebetween. It is noted that ledges 510 may be of any shape, quantity and/or distribution along opening 503a suitable to allow substance to pass therebetween while preventing passage of blocking apparatus 507 to cell 502. In this embodiment, spring 506 ends with a flat spiral 510, which serves both as a support, as well as a stopper from preventing blocking apparatus 507 to ascend into the cavity formed by spring 506 body. Partitions 510a serve as base for supporting spring 506 in several points, while allowing substance to flow between the spacings between neighboring partitions.

Fig. 6 illustrates another embodiment of the proposed sanitary system, in which the Venturi element 110 of Fig. IB is installed on the main water tank 90, uses a double piston 60. This allows concurrent pumping of solution from the two separate receptacles 85a-85b. Whenever the pressure in the Venturi pipe 213 raises the double piston 60 is pushed downwardly. This causes the solution that has been pumped in the preceding cycle into the cylinder to be ejected via valves 62 and 63, while at the same time valves 61 and 64 are closed. At the end of this stage spring 122 pushes back double piston 60 upwardly, for allowing pumping solution, similar to Fig. 1A. By changing the location of Venturi pipe 213, it is possible to invert the piston's operation and change the time when the pumped solution is ejected into the main water tank 90.

According to further embodiments of the present invention, the proposed system is integrated within toilet tanks, thus saving room space and enabling the production of complete toilet sets with the proposed system built in.

Fig. 7A schematically illustrates a section view of an integrated toilet sanitary system, according to an embodiment of the present invention, in which system 700 is installed within a toilet water tank 701 having a water flush handle 710, a float 711 which is threaded onto a tank filling tube 712 while floating in tank 701 at the water level while being tied to a filling valve 714 through a mechanical element such as stud 713. The proposed system may also include a lever mechanism for opening and closing filling valve 714. In addition, filling valve 714 may include a sponge-like membrane for uniformly distributing the water pressure.

System 700 is comprised of a Venturi element 715 (i.e., installed in lieu of a regular toilet tank inlet tube and being clamped to tank 701 with clamps 715a) having a side channel 715b (shown in Fig. 7B), an auxiliary pressure transmission tube 720 having an actuation regulator 721, a cylindrical accumulation cell 730, a first substance (e.g., detergent 741) receptacle 740, a first dispensing tube 742 being utilized for dispensing a desirable portion 742a detergent 741 into the water of tank 701, a second substance (e.g., air scenting substance 751) receptacle 750, and a dispensing tube 752 with dispensing nozzle 752a being utilized for dispensing air scenting substance 751 as an aerosol 752b to the ambient air. For the sake of clarity, some of the components of system 700 shown in Fig. 7A are specifically described in Fig. 7D.

Of course, receptacle 750 may be suitably pressurized as to enable the dispensing of air scenting substance 751 as an aerosol. A skilled person in the art may recognize alternate dispensing arrangements suitable for integration with different embodiments of the proposed sanitary system.

The pulling of handle 710 of tank 701, results with the emptying water from tank 101, thus float 711 slides down on filling tube 712 while pulling stud 713, hence forcing filling valve 714 to open, whereas the water level in tank 101 reaches to the initial level, valve 714 shuts off, thus the water flow through Venturi element 715 stops.

According to some preferred embodiments of the present invention, receptacles 740 and 750 are provided with transparent cap and level indicating means (not shown) such as transparent caps and notable colored buoy, for indicating the substances levels within receptacles 740 and 750. According to some other embodiments of the present invention, electronic alerting means are utilized for alerting on low substance levels locally (e.g., by a visual/audial means) or remotely (e.g., being connected to a corresponding smart house management system via a wired/wireless networking connection).

Fig. 7B schematically illustrates an enlarged section view of a Venturi element 715 of the proposed system during water flushing, according to an embodiment of the present invention, in which the flow of water from the upstream utility piping side 715c through Venturi element 715, to the water consumer (e.g., toilet tank) side 712a, enabled by valve 714 (e.g., buoy operated toilet inlet valve), induces a low pressure near a side channel 715b of Venturi element 715 and in tube 720. Whereas valve 714 shuts off (Fig. 7C), water flow through element 715 is disabled to the water consumer (e.g., toilet tank) side 712a, resulting with increased pressure in channel 715b and in tube 720.

The directional arrows in Figs. 7B-7C are used to indicate flow direction of water during the described operation.

Fig. 7D schematically illustrates an enlarged section view of system 700, in which accumulation cell 730 comprises an actuation portion 730a, an air scenting substance portion 730b, and a detergent portion 730c through which a double headed piston 731 can travel upwards or downwards, while having a first head 731a in the air scenting substance portion 130b and a second head 731b in the detergent portion 730c.

In one embodiment, the central rod that connects between the heads of the double headed piston 731 may be extended, such as its tip will exceed the upper wall of housing 701. This way, the user will be able to manually operate the piston 731, so as to perform manual initial filling of the pistons space. The opposite tip may also extend downwardly and activate a valve of a spray can containing a fragrant odor.

According to an embodiment of the present invention, low pressure in tube 720 (as illustrated in Fig. 7A), induces low pressure in portion 730a forces piston 731 to move up, thus exerting vacuum in portions 730b and 730c, and thereby pumping air scenting substance 751 from receptacle 750 into portion 730b and detergent 741 from receptacle 740 into portion 730b through pumping tubes 753 and 743, where high pressure in tube 720 (as illustrated in Fig. 7B), induces high pressure in portion 730a forces piston 731 to move down, thus head 731a forcing the pumped air scenting substance 751 in portion 730b to be pumped out through dispensing tube 752 towards dispensing nozzle 752a and to be dispensed as an aerosol 752b, while head 731b forcing detergent 741 in portion 730c to be pumped out through dispensing tube 742 into the water of tank 701. Accordingly, during water flush piston 731 moves upwards, thus concurrently pumping both substances into accumulation cell 730, whereas the water flushing ends piston 731 moves downwards, thus concurrently pumping both substances out from accumulation cell 730 to be dispensed to the water of tank 101 and to the external air. Tubes 742, 743, 752 and 753 comprise unidirectional valves, preventing back flow of substance back to the corresponding tubes and receptacles.

According to some other embodiments of the present invention, the connection of tube 720, pumping tubes 743 and 753, dispensing tube 742 and nozzle 752a - into accumulation cell 730 are oppositely with respect to piston 731, thus providing an opposite mode of operation with respect to the embodiment of Fig. 7D.

According to some embodiments of the present invention, piston 731 further comprises a spring 732 for exerting a assisting force to the actuation force induced by the Venturi-effect through tube 720 (i.e., when the utility water pressure is insufficient alone for the actuation of piston 731), thereby stabilizing piston 731 and limiting preventing exaggerated quantities of substances to be pumped / dispensed.

According to an embodiment of the present invention, system 100 further comprises an actuation regulator 721 in cylinder 721a through which tube 720 is connected to accumulation cell 730, regulating the pressure being transmitted from the side channel 715b of the Venturi element 720, thus providing an improved control of the acceleration of piston 731 during the pumping / dispensing cycle, thereby enabling the adjustment of dispensed quantity of detergent 741 and of air scenting substance 751 and of detergent 741.

Fig. 8A schematically illustrates a section view of a modular toilet sanitary system which is adapted to easy routine operation and maintenance during water flushing operation, according to an embodiment of the present invention, in which system 800 is comprised of a fixed venturi module 810, a actuation module 820, and two disposable kits of accumulation cells 830 and 840, onto which substance receptacles 830a and 840a are correspondingly threaded, wherein each of accumulation cells 830 and 840 is threaded into a fixed actuation element 821 of actuation module 820, and whereas substance receptacle 840a contains an air scenting substance, an outlet 841 of accumulation cell 840 is threaded with dispensing nozzle 850, and whereas substance receptacle 830a contains detergent, an outlet 831 of accumulation cell 830 is threaded with a fixed dispensing tube 823 (i.e., of actuation module 820) which is threaded into threading 814 of fixed venturi module 810. Each accumulation cell 830 and 840 comprises a piston 860 being attached to a spring 870 and being supported by piston 821a.

Venturi module 810 comprises a venturi element 811, a pressure outlet tube 812 and detergent outlet tube 813, each of tubes 812 and 813 is adapted with threading 814 for connecting to corresponding tubes of fixed actuation module 820, wherein pressure outlet tube 812 is threaded with a pressure transmission tube 822 and detergent outlet tube 813 is threaded with dispensing tube 823.

Actuation module 820 is comprised of two actuation elements 821 each of which comprises an actuation piston 821a, and both are connected to pressure transmission tube 822.

During the water flushing operation of toiler 801, water flow through venturi element 811, thus inducing low pressure in pressure outlet tube 812, and in pressure transmission tube 822, resulting with pistons 821a moving down within actuation elements 821. As a result, pistons 860 are being pushed down by springs 870, thus pumping substance from receptacles 830a and 840a into cavities 880 above pistons 860 of accumulation cells 830 and 840 correspondingly.

Fig. 8B schematically illustrates a section view of system 800 during dispensing, according to an embodiment of the present invention, in which toilet 801 is filled with water, thus water flow through venturi element 811 stops, the pressure increases in pressure outlet tube 812, and in pressure transmission tube 822, resulting with pistons 821a moving up within actuation elements 821. As a result, pistons 860 are being pushed upwardly, thus pushing up pistons 860, resulting in air scenting substance being dispensed through nozzle 850 to the toilet's ambient air, while detergent being dispensed through dispensing tube 823 and outlet tube 813 into the toilet's water tank.

Of course, while the above description illustrates accumulation cells 830 and 840 and receptacles 830a and 840a as disposable, multiple alternative designs of system 800 may comprise reusable accumulation cells and only disposable receptacles.

One skilled in the art will readily recognize alternate dispensing timing, being easy to configure. For example, choosing that substance will be pumped in/out above pistons 860 of accumulation cells 830 and 840, results with pumping substance into accumulation cells 830 and 840 (i.e., above pistons 860) when a user of toilet 801 start water flushing (i.e., resulting with low pressure in tube 822, pistons 821a moves downwards thus pistons 860 moves downwards pumping in substance from receptacles 830a and 840a), and dispensing substance out from accumulation cells 830 and 840 at the end of water flushing (i.e., when toilet 801 is refilled with water, the pressure below pistons 821a increases, thus pistons 821 and pistons 860 moves upwards pumping out substance from above pistons 860 of accumulation cells 830 and 840).

Fig. 8C schematically illustrates an opposite configuration of the proposed system, according to an embodiment of the present invention, in which substance is pumped in/out below piston 860 of accumulation cell 840, therefore, substance inlet 890 (i.e., through which substance is pumped into accumulation cell 840) and outlet 841 (i.e., threaded to nozzle 850 of Fig. 8B) are accordingly installed to the side of accumulation cell 840 and below piston 860, whereas water flushing begins, low pressure is induced through pressure transmission tube 822, piston 821 moves downwardly thus piston 860 is pushed down by spring 870, thereby dispensing air scenting substance at the beginning of water flushing, while in turn - as toilet 801 is refilled with water, the pressure in tube 822 increases thus piston 821 moves upwards pushing piston 860, thereby pumping substance into below piston 860 of accumulation cell 840, being ready for dispensing with the next water flushing. This mode of operation allows a toilet user to enjoy the freshly scented air immediately after using toilet 801. Of course, the corresponding shapes of piston 821 and piston 860 are negligibly different than pistons 821 and pistons 860 and do not affect the described mode of operation, yet illustrates another possible corresponding design of pistons 821 and pistons 860.

The detailed descriptions of the abovementioned embodiments of the proposed sanitary system, shows the adaption possibilities of the present invention into standard, commonly used sanitation systems to maintain an ongoing easy sanitation with minimal manual intervention, decreasing the burden of sanitary maintenance and allowing a high level hygiene.

Although embodiments of the invention have been described by way of illustration, it will be understood that the invention may be carried out with many variations, modifications, and adaptations, without exceeding the scope of the claims.
