Definitions
- the invention relates to a selective water distribution device for hygienic-sanitary plants like the toilets with water reservoirs, adapted to permit the water distribution to such plants to be metered depending on the actual need of the same water for cleaning said plants.
- the present hygienic-sanitary plants like the toilets with water reservoirs are provided with toilets connected by means of ducts to underground sewer systems, for the drainage of the human excrement, as well as reservoirs of adequate capacity disposed at a position above the respective toilets and operating by water falling, which water is contained within such reservoirs and is introduced therein through proper water mains, at pre-established and invariable amounts, so as such amounts be able to insure always an effective drainage of all the excrement materials of the persons.
- reservoirs are provided with suitable automatic regulating mechanisms for admitting water into the same reservoirs, generally having floating means, associated with sealing valve mechanisms, which are operated by means of manual operating push buttons and adapted to permit all the water amount contained within each reservoir to be drained in the toilet below it whenever cleaning of the excrement materials from this latter is required.
- suitable automatic regulating mechanisms for admitting water into the same reservoirs, generally having floating means, associated with sealing valve mechanisms, which are operated by means of manual operating push buttons and adapted to permit all the water amount contained within each reservoir to be drained in the toilet below it whenever cleaning of the excrement materials from this latter is required.
- the water amount for cleaning is always the same for each type of waste materials to be drained, is it a matter of both the urines and solid excrement which normally are respectively emitted several times or once a day only, while for these functions on the contrary it would be needed limited water amounts, in the first case, and higher ones in the second case.
- the present hygienic-sanitary plants do not allow to use on an optimum manner the water amounts being stored on the associated reservoirs of such plants, rather they involve water consumptions higher than those actually required, and thus need also higher electric energy consumptions for power supply of the aqueduct pumping plants for the distribution of a greater water amount through the hydraulic plants connected to said reservoirs.
- FIG. 13 schematically illustrate a water reservoir 13, connected by adequate pipings (not shown) of a water supply plant and communicating on its lower side with a hygienic - sanitary plant disposed below it and provided for the drainage of the human wastes, like for example one hygienic toilet (also not shown), which is connected through suitable pipings with at least an underground sewer system, sinkholes or similar systems for waste collection and discharge.
- This reservoir 13 is made with such a storage capacity of a maximum water amount that to insure as usual an effective drainage of the solid human wastes like excrements, and is also provided with a suitable automatic water regulating mechanism inside the same reservoir, comprising advantageously a floating element 14 of per se known type, which is set for permitting the water to be introduced into the reservoir up to a pre-established maximum filling level, marked with the reference numeral 15, and associated with at least a valve member (not shown in the Fig.
- the reservoir 13 is provided with sealing valve mechanisms which, as usual, provide for water discharge in the toilet below it, for cleaning thereof.
- the present sealing valve mechanism is substantially formed by at least two sealing valve members 16 and 17 of per se known kind, affecting respectively a first and a second horizontal conduit 18 and 19, connected at their first end to the reservoir 13 at two different water levels and at their second end being joined together and to the drainage conduit 20 directed downward and communicating with the hygienic toilet disposed below it (all these items are drawn dashed).
- valve members 16 and 17 are operated by respective manual operating push buttons 21 and 22, which permit their automatic delayed action return to the starting closing position, so as the temporary displacement on the opened position of each valve member does allow the water to be drained through the conduit associated therewith.
- the horizontal conduits 18 and 19 are connected to the reservoir 13 respectively on the bottom level thereof and the water level comprised between such bottom level and the above described maximum filling level, so that the opening of either the valve members 16 or 17 causes the water to pass in the drainage conduit 20, respectively through either the conduit 18, with consequent drainage of the whole water contained within the reservoir 13, up to its bottom level in which such conduit 18 is connected, or the conduit 19 with consequent drainage solely of the water head comprised between its maximum filling level and the level where such conduit 19 is connected thereto.
- the water amounts being discharged in the two specified cases are selected with such volume as to provide an effective drainage from the toilet of the solid wastes like excrements, in the first case, and the liquid wastes like urines etc.. in the second case, which evidently require a water amount smaller than the previous one.
- valve members 16 and 17 may be operated also automatically instead manually, i.e. by providing at least an associated solenoid valve (not indicated on the Figure) or electromechanical, pneumatic, hydraulic and the like member, which is controlled automatically by a main control member (not shown) associated to the reservoir, with such timed make as to permit the selected water level to be discharged depending on the drainage needs of the wastes from the toilet, and then to prevent the additional water which will be admitted on the reservoir 13 for performing a subsequent discharge cycle with the same described operative criteria from being discharged therefrom.
- the conduits 18 and 19 and any additional conduit may be connected to the reservoir 13 also in manners different than those described, i.e.
- each one of conduits 18, 19 and 24, 25 and the possible additional conduits may be height adjusted so as to change the water discharge level, by using for this object the same conduits without the need to provide further conduits.
- each one of such conduits as for example the conduit 24 may be provided with a movable part 291, slidable vertically on the associated conduit and movable at different regulating heights, so as to change the filling level and therefore the water discharge level on the reservoir 13.
- the reservoir 13 is connected to a common drainage conduit 20 through at least two horizontal conduits 18 and 19 (drawn dashed), situated at two different levels for permitting to discharge two different water amounts therefrom, in the present case respectively of the whole water contained within the reservoir 13 and the water volume corresponding to the water head provided between the maximum filling level and the level where the conduit 19 is connected thereto.
- valve member 30 which is shaped as a manually operated selector valve member, as evident particularly from the Figs.
- the present example is substantially constituted by a rotating annular disc 31 provided with two sealing valve members 32 and 33, offset from each other of a fixed angular distance equal to that provided between the one and the other one of the different conduits 18, 19, which in the present example is of a right angle, but which of course may be also different and variable.
- the common drainage conduit 20 is connected to the rotating disc 31 at such position as not to be affected by any of the two sealing valve members 32 and 33 of the same disc, whatever operative position this latter is rotated.
- the reservoir 13 is always provided with an overflow conduit 23 positioned and foreseen as previously described and communicating directly with the common drainage conduit 20.
- the rotating disc 31 is moved on the operative rest position, where the sealing valve members 32 and 33 are coinciding respectively with the conduits 18 and 19, by turning off the outflow port thereof.
- the conduit 19 is put into communication with the common drainage conduit 20, with consequent discharge on the toilet below it of a limited water amount, equal to the volume defined between the maximum filling level of the reservoir 13 and the level where the conduit 19 is connected to the same reservoir.
- the rotating disc 31 is provided with adequate devices (not shown) like i.e. springs and the like, adapted to bring back the same disc always on its starting rest position, whenever operative position it is moved, with a pre-established delay time and such as to permit always the water amount respectively selected to be fully discharged from the reservoir to the toilet.
- the valve members 32 and 33 may be operated automatically instead manually, by providing for each conduit i.e. at least a respective one-way solenoid valve or a single multi-ways solenoid valve having separated control means, acting as valve members, or electromechanical, pneumatic, hydraulic etc..
- conduits 18 and 19 and the possible additional conduits may be connected to the reservoir 13 at positions different than those described, by arranging i.e. such conduits on a vertical direction in a manner that their free ends enter the same reservoir at different heights thereof, in order to obtain always the same above specified functions, as it is evident from the conduits 37 and 38 affected by the rotating disc 31.
- each one of the conduits 18, 19 and 37, 38 and the possible additional conduits may be height adjusted with the same criteria, by providing to this aim for example together with the respective conduits a movable part like the part 371, slidable vertically (in this case, with respect to the conduit 37) in order to be able to be moved at different adjustment heights, so as to change the filling level and therefore the water discharge level on the reservoir 13.
- the water reservoir 13 is provided with the customary overflow conduit 23, introduced vertically inside said reservoir and communicating directly with the common drainage conduit 20 arranged below it, as well as a valve member affecting such drainage conduit and formed by at least a solenoid valve 39 or similar member, controlled by a reservoir main control member (not shown) and operable at the opened position thereof, where it is kept at such position for different and variable time periods depending on the water amount to be discharged, which is selected by operating suitable push buttons of the reservoir associated to the different water filling levels and therefore to the different water amounts to be discharged, which push buttons on the present example are constituted by the push buttons 40 and 41 for selecting respectively the available maximum water amount and a smaller amount thereof. Then, at the end of each selected time period of opening the solenoid valve 39, this turns off again automatically by preventing additional water from leaving the reservoir 13 and permitting additional water to be introduced therein up to the maximum filling level thereof.
- a fourth embodiment of the selective water distribution device according to the invention is described on the Figs. 7 and 8, wherein it is noted that such device is housed within a box-like unit 42 interposed removably between both the common drainage conduit 20 arriving from the water reservoir situated above it (not shown on the Figure), or directly from water supply tubings, and the inlet side of the hygienic toilet (not shown too).
- the device is formed as previously by at least a valve member 43 affecting the outflow port of the drainage conduit 20, in the present example formed by a gate sliding rectilinearly being controlled by a solenoid valve 44 or the like, from a rest position in which such gate fully turns off the drainage conduit 20, at the position indicated on Fig.
- an overflow conduit 23 is provided, arriving from the reservoir and passing through the drainage conduit 20, which overflow conduit isn't affected by the slidable gate 43 and is able to put such reservoir directly into communication with the toilet for the same previously described objects.
- Fig. 9 it is shown a constructive variant of the device of Figs.
- a partition wall 48 acting as support and extended rectilinearly and parallelly to the same gate, at a position upstream it in the water flow direction (arrow B), which wall is provided with a plurality of through holes 49 traversed by the water and a short sleeve 50 providing another hole 51 (see enlarged item thereof on Fig.
- the overflow conduit 23 is forced inserted and whose other end is slightly projected to permit the gate 43 to rest tightly thereon, when it is at its rest position where it fully shuts off the outflow port of the drainage conduit 20, except the overflow conduit 23, from which position such gate may be moved by the solenoid valve 44 to the opened position thereof with the same operative criteria previously described.
- Figs. 9A the overflow conduit 23 is forced inserted and whose other end is slightly projected to permit the gate 43 to rest tightly thereon, when it is at its rest position where it fully shuts off the outflow port of the drainage conduit 20, except the overflow conduit 23, from which position such gate may be moved by the solenoid valve 44 to the opened position thereof with the same operative criteria previously described.
- 10 and 11 show two different possible versions of the partition wall 48, which in the first case is shaped with several supporting ribs 52 convergent to each other along the sleeve 50, thereby providing a set of openings of triangular shape 53 for the water flowing therethrough, which openings are fully occluded by the gate being moved to the rest closing position thereof (which position is drawn dashed), and which in the second case is shaped with a set of circular holes 54 and 55 having different diameter and arranged approached to each other, for the water flowing therethrough, which are also fully occluded by the gate being moved to the rest closing position thereof.
- the box-like unit 42 together with the associated component parts housed therein may be housed directly also inside the toilet, at a suitable position thereof, instead of being interposed between said toilet and said reservoir, permitting to perform always the same above described functions.
- Fig. 12 it is shown a fifth possible embodiment of the present device, in which it is noted that it is substantially formed by at least a photoelectric sensor 551 or sensor of other type adapted to detect the presence of wastes within the toilet, which is adequately positioned inside the toilet and is operatively connected to the previously described valve members, associated to the different levels of water to be discharged on the same toilet, or it may be connected to at least a solenoid valve 552 or similar valve member provided to control the water discharged and entering the toilet.
- such sensor 551 is associated with a light reflecting element like i.e. a mirror 553, disposed at the level of the toilet bottom side, on the collecting zone of the discharged human wastes, and is calibrated in such a manner as to transmit a luminous light signal and to receive it reflected by such reflecting element 553.
- a light reflecting element like i.e. a mirror 553, disposed at the level of the toilet bottom side, on the collecting zone of the discharged human wastes, and is calibrated in such a manner as to transmit a luminous light signal and to receive it reflected by such reflecting element 553.
- this sensor is calibrated in such a manner as to recognize the type of discharged waste, either solid or liquid one, by means of two different threshold levels of the signal reflected by the reflecting element 553, and passing through the discharged human wastes and collected on the toilet bottom side zone, respectively a first threshold level in presence of solid wastes, wherein the reflected signal is received with too weak level or quite it is received at all by such sensor in the case in which too opaque solid wastes are provided, and a second level wherein the reflected signal is received with a level higher than the previous one, by passing through less opaque liquid wastes.
- the sensor 551 provides to control the valve members so as to adjust the volume of the discharged water, thereby adapting it to the type of wastes to be discharged, namely that in presence of the first level of such signal it controls the discharge of the greatest water amount contained within the reservoir, and that in presence of the second level of such signal it controls the discharge of a water amount smaller than the preceding one.
- an additional sensor 554 of the type referred to positioned in a different manner inside the toilet and emitting a luminous light signal which isn't reflected in that a reflecting element isn't provided, which signal on the contrary is intercepted in a different manner by the wastes being collected on the bottom side zone of said toilet, depending on the type e quantities thereof, thereby providing likewise to control the different volumes of water to be discharged with the same above specified criteria.
- either the sensor 551 or 554 then provides to delay in a variable manner the make of the same solenoid valve, in presence of either said first or second level of the received signal, or of the different types of wastes, thereby providing for discharging different water amounts for the same specified functions.
- the regulating system of the discharged water volume may be obtained also with sensors or devices of type different than those described solely by way of example, which are interacting with the valve members controlling the water amount to be discharged depending on the wastes discharged on the toilet, thus without departing from the protection field of the present invention.
- Fig. 13 now shows a sixth possible embodiment of the present device, wherein it is noted that a drainage hole 57 is provided on the bottom side wall 56 of the reservoir 13, which hole is connected to the drainage conduit 20 leading to the toilet situated below it (not shown), inside which at least two valve members 58 and 59 separated from each other are provided, constituted by a respective horizontally slidable gate operable from a closed to an opened position thereof by actuating an associated manual push button (not shown), and which can be turned off automatically again by means of a suitable delaying system, after pre-established time periods, such that to allow all the water provided for each selected discharge cycle to be discharged therefrom.
- a drainage hole 57 is provided on the bottom side wall 56 of the reservoir 13, which hole is connected to the drainage conduit 20 leading to the toilet situated below it (not shown), inside which at least two valve members 58 and 59 separated from each other are provided, constituted by a respective horizontally slidable gate operable from a closed to an opened position thereof by actuating an associated manual push button (
- a vertical conduit 60 extended upward for a determinate height from the bottom side wall 56 of the same reservoir, at a level lower than the maximum filling level of water inside the reservoir, and provided with a movable part 61 movable at different heights of such conduit, in order to change in this way the height of this latter and therefore the water discharge level through the same conduit.
- these water volumes are selected in such a way as to allow the solid wastes like the excrements as well as the liquid ones like the urines to be respectively drained effectively from the underlying hygienic toilet.
- Figs. 14 and 15 show now a plan view of two different versions of a constructive item of one of the slidable gates, for example the gate 59.
- each one of such gates in addition to a rectilinear rigid rod 62, operable with the associated manual push button for providing the displacement to its two operative positions, is also provided with a suitable delaying mechanism associated to such rectilinear rod to delay the return of the same rod to the rest position thereof for the above mentioned reasons.
- this delaying mechanism is advantageously constituted by a compression spring 63 connected to the end of the rod 62 situated near the manual push button (not shown), and stressing the same rod in such a way as to keep it normally at its rest position, as well as a pawl 64 provided with a rectilinear portion 65 and a bent portion 66 joined together, wherein the free end of the rectilinear portion 65 of such pawl is pivoted rotating on a stud 67, provided at the level of the opposite end of said rod and is urged by a compression spring 68 to move to a rest position, shown on Fig. 14.
- the opposite end of the rod 62 is provided with a projected pin 69 co-operating with the outer profile of both the rectilinear and bent parts 65 and 66 of the pawl 64 during the displacement of said rectilinear rod from the one to the other one of its operative positions.
- Fig. 15 it is noted another possible embodiment of the delaying mechanism referred to, which is substantially identical to that one of Fig. 14 and is different therefrom only in that in this case the rod 62 is provided with a movable portion 70, articulated to a pin 71 of the associated gate and co-operating with the rotating pawl 64 in the same manner and for the same above mentioned purposes.
- the described delaying mechanism may be made also in different ways, to perform always the same function, for example it may be unprovided of the pawl and the associated spring and provided with at least a pneumatic bellows, an electric, hydraulic, pneumatic etc.. operated piston associated with the end of the rod 62 situated near the manual push button, acting on the same rod in a manner to return it back to the rest position thereof, within the pre-established delay time, thus without departing from the protection field of the present invention.
- the reservoir 13 is provided with an overflow conduit 23 inserted vertically through the drainage hole 57 and communicating with the drainage conduit 20 situated below it, for the same functions set forth previously.
- a first rest position (Fig. 16) where both the gates occlude the drainage hole 57 and therefore no water discharge takes place
- a second position Fig. 17
- a first gate in this case the gate 58
- a third position Fig.
- the present device permits to obtain a selective distribution of the water for cleaning hygienic-sanitary toilets at different amounts thereof, adapted to the actual need of discharging the wastes from said toilets, with consequent optimum performances and consumption savings of both water and electric energy needed for providing pumping and circulation of such water in the hydraulic plants and the possibility to design undersized sewer systems for the drainage of such wastes and the water.
