Definitions
- the present invention relates to a multiple draining system for sinks or basins, mainly for sanitary domestic use.
- the invention is relative to a draining system provided with a simple and reliable construction that allows to recover wastewater from sinks or basins when it is desired to use such water for further processing or other direct uses.
- FIG. 1 Another very used system is that shown in FIG. 2 wherein a first upper element of the drain is fixed to the bottom of the basin by means of a central fixing pin, which being screwed to the lower element of the drain, placed under said basin bottom, joins integrally said first and said second element thus forming the drain body.
- waste pipes usually made of plastic, either screwed to that portion or through a pressure gaskets.
- the pipes may or may not be siphoned and have the task of carrying wastewater to collection and separation tanks and from these to the sewage system.
- the drains are made of materials of various types: metal, plastic or both metal and plastic.
- a more practical solution in order to achieve such recycling possibility, consists in realizing a double draining circuit controlled by a diverter under the basin.
- the recovered water is directed to the garden or to a storage container so as to be subsequently used for gardening or other suitable use.
- Such system is undoubtedly useful, effective to the purpose, but it certainly has some considerable drawbacks and complexities for the user.
- the patent application GB 2430444 describes a grey water draining system comprising an inlet for grey water (sink drain), first and second outlets for discharging grey water, the first outlet being connected to a draining system (to sewage) and the second outlet being connected to a recovery system, a valve for selectively directing water to the first outlet or to the second outlet, the valve being positioned between the inlet and the first outlet or the second outlet, wherein the valve is activatable between first and second positions connecting alternatively the inlet to the first outlet and the inlet to the second outlet.
- the valve comprises an en bloc sleeve and is operated by rotating the plug for closing the inlet (sink drain). Therefore, the plug and the valve are an en bloc piece which has to be completely made for that purpose, thus basically modifying the basic structure of a traditional system.
- Patent application FR 3000508 describes a recuperator of domestic water comprising a three-way valve which intercepts the water waste pipe after the siphon and is composed of a cylinder activated by a remote control by means of a rod capable of causing the cylinder to rotate by 90°. Through the rotation of the cylinder, water is directed straight to the sewage system or to a storage container wherein an electric pump, when activated, makes it possible to reuse the water for further purposes.
- This solution appears to be rather complex and encumbering and not applicable to traditional systems.
- the technical problem at the basis of the present invention is therefore that of realizing a new device that inserted in a suitable draining system, that is in draining systems on the market which do not have any chokes or interruptions, when used, allows to overcome the above said drawbacks; just the opposite, it allows to realize, in the same spaces, a substantially different system having an appearance the same as those at present on the market and which allows to operate quickly, even for small quantities of water, being able to control visually the real operation of the activated draining system and even with a full sink it is possible to choose the type of draining system before activating its opening.

Abstract
Description
- The present invention relates to a multiple draining system for sinks or basins, mainly for sanitary domestic use. In particular the invention is relative to a draining system provided with a simple and reliable construction that allows to recover wastewater from sinks or basins when it is desired to use such water for further processing or other direct uses.
- At present the discharge of water for civil use, from basins, sinks or other systems mainly for domestic use, containing food or detergents in greater or lesser amounts, takes place through a collecting drain. The drain is fixed on the bottom of a collecting basin (for example wash-basin or sink) usually by means of a ring nut, underneath the bottom, which screwed on the drain with the insertion of a gasket, making it integral to such bottom, as shown in
FIG. 1 . Another very used system is that shown inFIG. 2 wherein a first upper element of the drain is fixed to the bottom of the basin by means of a central fixing pin, which being screwed to the lower element of the drain, placed under said basin bottom, joins integrally said first and said second element thus forming the drain body. - In both solutions, to the underneath end portion of the drain there are connected waste pipes, usually made of plastic, either screwed to that portion or through a pressure gaskets. The pipes may or may not be siphoned and have the task of carrying wastewater to collection and separation tanks and from these to the sewage system.
- The drains are made of materials of various types: metal, plastic or both metal and plastic.
- In order to shut the drain various systems are used: with time, the usual plug has been replaced by the traditional filter plug or basket which is at present the most used one in modern kitchens and which, at the same time, acts as a plug and a filter for the drain (
FIG. 2 ) or shutting systems having a back lever returning or by means of a rod operated by a knob. - The wise user, especially in those countries where water is very scarce and precious, realizes that a great quantity of water is discharged into the sewage system which instead could be well channeled for other uses.
- To this purpose a lot of systems have been realized for recovering “grey water” from the bathroom such as that from the washbasin, from the shower or from the bathtub, as well as rainwater, mainly to be recycled in the W.C. as the W.C. flush is where water is used the most.
- Alternatively, a great number of systems for recovering water have been realized through the treatment of the same W.C. wastewater or through systems for recovering grey water through degreasing or phytodepuration, that however have high costs and a set of dimensioning problems not always solvable concerning phytodepuration.
- Just as much attention has not been given to recycling “clean” water from the kitchen or from the bathroom that in the everyday use all together became substantial for alternative uses. In fact, it frequently occurs that much of the water used in the domestic wastewater drainage circuit, wherefrom it is discharged into the sewage system, is not really contaminated by any element such as detergents or other pollutants or not biodegradable, in other words containing totally biodegradable detergents in use at present. Let's consider when vegetables or fruits are cleaned or washed, when you wash your hands while cooking, the pasta or vegetables cooking water, or when dusty objects are washed. Again, washing continuously kitchen tools while cooking produces “dirty” water which is not really “dirty”, on the contrary it is absolutely useful for further uses and specifically for some domestic uses such as watering plants or the lawn.
- In these cases, that water is therefore potentially suitable for recycling in natural ways, other than the mere W.C. flush.
- Sometimes a big pot or other container is put in the sink when it is desired to collect the water used and then recycle it directly watering plants. Such system is certainly not very convenient and cannot be used immediately. Therefore, as in the above said cases, the water quantity usually used up/discharged in sinks cannot be recycled any more or at the very least not very easily.
- A more practical solution, in order to achieve such recycling possibility, consists in realizing a double draining circuit controlled by a diverter under the basin. In this way, with two systems, one for the sewage and one for recovering, the recovered water is directed to the garden or to a storage container so as to be subsequently used for gardening or other suitable use. Such system is undoubtedly useful, effective to the purpose, but it certainly has some considerable drawbacks and complexities for the user.
- First of all, whenever the user wants to recycle even a small quantity of water, he must bend down towards the front part of the cabinet which is usually fitted under the wash-basin, open its wings, operate the gate acting as a diverter, close the cabinet, and do the opposite to go back to the sewage system.
- Such “D.I.Y.” system shows a lot of inefficiencies and drawbacks: it is not immediate, it is necessary to bend twice in order to operate it in one way and then go back to the previous condition (opening/closing cycle); it does not allow the user to see if the diverter is in the sewage state or in the recovery state; it takes up precious room under the wash-basin; it is rather expensive, even for the less expensive drains, for the number of items to buy and/or to adjust. Also the possibility of using remote control systems, such as those on the market, involve a series of adjustments in order to be applied to the wash-basin. These solutions prove to be complex solutions, since anyhow, it is necessary to modify and/or to make a hole in the cabinet whereon the wash-basin rests as well as to make adjustments that many users do not like.
- Furthermore, the use of the products present on the market would result in systems having considerable dimensions. In practice, it derives that recovery systems are rarely realized in sinks for all the above said reasons of usage drawbacks, of lack of immediate visualization of the sewage or recovery systems, of appearance, of costs.
- For example, the patent application GB 2430444 describes a grey water draining system comprising an inlet for grey water (sink drain), first and second outlets for discharging grey water, the first outlet being connected to a draining system (to sewage) and the second outlet being connected to a recovery system, a valve for selectively directing water to the first outlet or to the second outlet, the valve being positioned between the inlet and the first outlet or the second outlet, wherein the valve is activatable between first and second positions connecting alternatively the inlet to the first outlet and the inlet to the second outlet. It is to note that the valve comprises an en bloc sleeve and is operated by rotating the plug for closing the inlet (sink drain). Therefore, the plug and the valve are an en bloc piece which has to be completely made for that purpose, thus basically modifying the basic structure of a traditional system.
- Patent application FR 3000508 describes a recuperator of domestic water comprising a three-way valve which intercepts the water waste pipe after the siphon and is composed of a cylinder activated by a remote control by means of a rod capable of causing the cylinder to rotate by 90°. Through the rotation of the cylinder, water is directed straight to the sewage system or to a storage container wherein an electric pump, when activated, makes it possible to reuse the water for further purposes. This solution appears to be rather complex and encumbering and not applicable to traditional systems.
- The technical problem at the basis of the present invention is therefore that of realizing a new device that inserted in a suitable draining system, that is in draining systems on the market which do not have any chokes or interruptions, when used, allows to overcome the above said drawbacks; just the opposite, it allows to realize, in the same spaces, a substantially different system having an appearance the same as those at present on the market and which allows to operate quickly, even for small quantities of water, being able to control visually the real operation of the activated draining system and even with a full sink it is possible to choose the type of draining system before activating its opening.
- Such problem is solved by means of a multiple draining system according to various embodiments, starting from only one concept for all solutions: to make the drain, from just an element of interception and connection to the draining system, become only one system of interception and diversion of the draining with immediate control, either when the draining is open or closed being able to see the active draining function.

FIG. 1 there is shown a first commercial solution having a threaded through drain B fixed on the upper surface S of a draining plane A or basin bottom by means of a ring nut D. InFIG. 2 there is shown a second commercial solution wherein a drain comprises an upper element G mounted on the upper surface S of the bottom A of the basin and a body H underneath said surface and fixed to the upper element G by means of a through pin I. A filter plug T is then provided to reversibly close the same drain. - The object of the present invention starts from the assumption of an immediate control, which is easily visualizable, cost effective and of easy maintenance, in order to select either the sewage system or the recovery system. The general principle is therefore the direct activation from the wash-basin.
- In fact, as shown in figures from 3 to 67, the present invention relates to a
multiple draining system 1, 100-121 for sinks or wash-basins generally for domestic use, comprising adrain waste pipe - The waste pipe is a rectilinear pipe extending along an axis X-X, mutual to the drain axis, and is provided with the
primary waste pipe 30 for the sewage system and with at least asecondary waste pipe 35 for the recovery system. - In particular, the multiple draining system is characterized in that it comprises means for diverting the wastewater flow from the basin which are selectively activatable so as to discharge water through said
primary waste pipe 30 or through saidsecondary waste pipe 35, wherein said diverting means are accommodated inside said waste pipe and are activatable by means of a control positioned above the level of the bottom A of the basin. - The solution described in the appended figures from 3 to 6 depicts a first embodiment of the present invention.
- In that solution, as shown, the perforated surface of the bottom A of the basin for collecting water, such as a wash-basin, sink or the like, accommodates a
drain 2 which preferably has acircumferential groove 2 a for bearing a flange of acommand element 4. In its turn, thedrain 2 comprises afirst bearing portion 20 on the inner surface S of the bottom A of said basin and a second through engagingportion 21 with said draining hole F of the basin. Further, thesecond portion 21 is provided with anend 23 for a sealed connection with saidwaste pipe 3. Thedrain 2 has then a suitable outer thread (not shown) on theend 23 whereto aring nut 10 shall be screwed for the subsequent tightening to the basin A with the insertion of agasket 11. Internally, thesecond portion 21 has anannular bearing step 24 for arotating element 5 described later. In case, thedrain 2 may also havelateral apertures 22 for collecting overflow water coming from anoverflow pipe 9 of the basin A. - The
command element 4 has anannular support flange 42 on said circumferential groove of thefirst portion 20 of thedrain 2, which flange is provided withgripping elements 41 so as to activate the rotation of a rotating element orcylinder 5. Furthermore, from theflange 42 it extends acylindrical wall 43 coaxial with thesecond portion 21 of thedrain 2. Thecylindrical wall 43 has a bottom 44 provided withradial apertures 4 a for the water flow and a perforated central axial portion. Laterally, that wall may compriseapertures 40 for draining overflow water, coming from theoverflow pipe 9 of the basin A, which cooperate with the above saidapertures 22 of thedrain 2. Saidcommand element 4 is integrally connected with a rotating element orcylinder 5 underneath by means of apin 6, preferably perforated, for the transmission of the rotation given by said control element; the whole is contained in thewater waste pipe 3 of the basin. Thecommand element 4 is then realized in female form or basket so as to fit the usual filter plugs 8 present on the market. - The
filter plug 8, preferably as shown inFIG. 3 , comprises a cup-like portion 80 whose aperture is defined by aflange 81 and whose bottom 82 is a perforated grid (holes not shown in figure) for filtering wastewater. At the centre of the bottom 82, raises aknob 8 a for controlling the closing of the plug by locking together with thedrain 2. In correspondence of theknob 8 a, but from the outer surface of the bottom 82, it departs, in a straight way, anaxis 83 for the engagement with theseat 62 of thepin 6 for the connection between thecontrol element 4 and therotating cylinder 5. - In particular, the
pin 6 comprises ahead 61 provided with aseat 62 for engaging a plug/basket 8 and of a protrudingedge 63 for resting on the bottom 44 of therotatable element 4. That head passes through the above said central hole of therotatable element 4, and continues with anelongated portion 64 ending with anend 65 for the integral engagement with therotating cylinder 5. In this configuration, the rotation given by therotating element 4 by acting on thegripping elements 41 selectively activates the water flow towards either one or the other draining systems, as later described. - The above said means for diverting the flow of the water into a sewage pipe or into a recovery pipe are preferably constituted by a rotating element or
cylinder 5 which is commanded by the above saidcommand element 4. Therotating cylinder 5 is generally made up of one or more pieces integral one with the other which together with therotating element 4, with or without thepin 6, acts as a control and diverting system, easy to place in or to remove from thedrain 2 for maintenance and cleaning. - In particular, as better shown in
FIGS. 6 and 7 , therotating cylinder 5 extends longitudinally along the axis X-X and has afirst end 50 for the connection with thedrain 2 and asecond end 51 for the connection with thewater waste pipe 3. Thefirst end 50 carries aflange 7 for the purpose of centering and improving the solidity of the assembly formed by thecontrol element 4 and therotating cylinder 5. In fact, that flange rests on thestep 24 of thesecond portion 21 of thedrain 2. Furthermore, thefirst end 50 is axially perforated having a plurality ofradial apertures 52 and acentral aperture 53 for receiving the above saidpin 6. Anannular seat 54 can be formed in said flange so as to accommodate a seal O gasket (FIG. 3 ). Thesecond end 51 is axially perforated as well. In particular, anaperture 55 in the form of a circle sector extends preferably for 180°, about acentral hole 56 for the engagement with saidsecond end 65 of thepin 6. As later described, thataperture 55 is for draining the water in the sink into the sewage system. The remainingportion 57 of thesecond end 51 of therotating cylinder 5 is axially closed. Preferably, the outer circular edge of thesecond end 51 has a groove 58 (FIG. 6 ) for accommodating a relative seal 59 (FIG. 3 ). Furthermore, the lateral wall of therotating cylinder 5 in the proximity of saidsecond end 51 has awindow 58 that preferably extends for about half the circumference of the cylinder in the position axially opposed with respect to theaperture 55. Such window has the function of diverting the water in the sink towards the recovery pipe or secondary waste pipe, as later described. - The
waste pipe 3, wherein there is coaxially accommodated the above saidrotating cylinder 5, comprises afirst end 31 provided with aflange 31A for a sealed connection with the end of thesecond portion 23 of the drain 2 (FIGS. 8 and 9 ). In correspondence of asecond end 32, the inner surface of thepipe 3 comprises restingelements 33 or first wall of a gate-like device, wherein said first wall has afirst aperture 34 for the water flow which extends similarly to a circle sector about an axial restingseat 39 as a centering and rotation point of thepin 6. Preferably, thefirst aperture 34 extends for about half a circle, more preferably for an angle less than 170°/180°. Further,such pipe 3 has laterally apertures or outlets on the lateral wall. Asecondary waste pipe 35 is formed between saidfirst wall 33 and saidflange 31A and is angled towards saidflange 31A, so as to allow the recovery draining when the system is closed. Afurther pipe 36 is connected to the sink overflow and it shall always be underneath saidfirst wall 33, that is between the free edge of thesecond end 32 and said first wall. In particular, saidfirst pipe 35 and saidfurther pipe 36 are positioned diametrically opposed. Furthermore, the lateral wall of therotating cylinder 5 comprises twosecond apertures FIG. 9 ) so as to serve as safety overflow in case the recovery system of thesecondary waste pipe 35 is full or in case of a malfunctioning of the system. - Moreover, the rotation of the
rotating cylinder 5 inside thewaste pipe 3, operated by means of the action of the fingers of a hand on thegripping elements 41 of thecommand element 4, is controlled and limited by stop means 18 and 19, such as protrusions respectively of the inner surface of thewaste pipe 3 and of the outer surface of therotating cylinder 5. - Now hereinafter it will be explained how the draining
system 1 previously described works. - As shown in
FIG. 4 , the fluids from thedrain 2 will be directed to the sewage system when, acting by rotation on thecontrol element 4 by means of the grippingmeans 41, the rotation given about the axis X-X is transferred to the rotating cylinder through thepin 6. Thus, therotating element 5 places itself with theaperture 55 of thesecond end 51 overlapping the closed portion of thefirst wall 33 of thewaste pipe 3. Therefore, it will axially prevented the water flow through thesecond end 32 of thewaste pipe 3 and, consequently, the water from thedrain 2 will be directed to thesecondary waste pipe 35 thanks to thewindow 58 of therotating cylinder 5 which is in communication with saidsecondary waste pipe 35, as shown by the arrow. Thus, it is possible to recover the water contained in the sink for various uses such as watering gardens or plants in pots. - Instead, by rotating the
command element 4 into the opposite direction, the above saidaperture 55 of therotating element 5 will be axially overlapped to thefirst aperture 34 of thefirst wall 33 of thewaste pipe 3, thus allowing the water flow axially through thesecond end 32 of thewaste pipe 3 so as to reach the sewage system, as shown by the arrow ofFIG. 5 . At the same time, thewindow 58 of the lateral wall of therotating cylinder 5 places itself against the closed lateral wall of thewaste pipe 3, opposite thesecondary waste pipe 35 for recovery the water from the sink. - It is to keep in mind that the above said rotating operations in one direction and in the opposite direction are controlled by the
control element 4 and the above said stop means 18,19 regulates the rotation width to make either the apertures or the outlets or the window overlap or not one with the other so as to divert the water from the sink into the sewage system or into the recovery system. - In
FIG. 10 there is shown an embodiment variant of the previously described solution, having, as a closing system for the sewage system, instead of the overlapping of the two apertures, asnap system 100 fixed inside thewaste pipe 300. The parts in common with the previous embodiment are referred to with the same reference number. - In this solution, the
pipe 300 is generally the same as thewaste pipe 3 previously described. In particular, its inner surface of the lateral wall comprises an annular thickening or narrowing 301. Inside the pipe there is inserted a system comprising apin 600, completely similar to thepin 6 of the rotating mechanism previously described, which freely passes through aplug 8 b similar to the above describedplug 8 but suitably perforated.Such plug 8 b is independently connected by means of saidpin 600 with anotherplug 12 provided with a throughthread 12 b that allows the threaded control or thegripping element 13 to integrally connect with thecommercial snap device 14 fixed on aseat 15 of thepipe 300. On the circumference of theplug 12 there is an O-ring 12 a which acts in correspondence of the narrowing 301 of the lateral wall of thepipe 300 allowing alternatively the water to flow or not into the primary waste pipe 30 (FIGS. 11a and 11b ). - In other words, the
second end 302 of thepipe 300 defining thewaste pipe 30 comprises a plurality ofradial holes 303 for the draining of the water along the axis X-X of the pipe directly into the sewage system, and a central seat for engaging asnap device 14 apt at controlling the positioning of aplug 12 for closing the water flow through said plurality ofholes 303. Practically, by means of thegripping element 13 it is possible to operate on thepin 600 which in turn pushes or pulls theplug 12 on thesnap device 14. When theplug 12 is activated, thegasket 12 a is pressed in correspondence of the narrowing 301 of thepipe 300 to prevent the water from flowing into theprimary waste pipe 30 and allow the water to flow into the secondary waste pipe 35 (FIG. 11a ), on the contrary, when theplug 12 is not activated, that is moved towards thedrain 2, the gasket moves away from thestep 301 thus allowing the water to flow into the primary waste pipe 30 (FIG. 12b ). - A
position reader 16 protrudes from the grippingelement 13 and is connected to the snap device by means of a return mechanism 17 (FIG. 10 ). - In
FIG. 12 , there is shown asystem 101 where the selective closing of theprimary waste pipe 30 is realized by means of aplug 12 that stops against a narrowing 301 of thewaste pipe 3. The parts in common with the previous embodiment are referred to with the same reference number. In this case, the lifting/lowering mechanism of theplug 12 comprises an articulated pin (not shown) with a first end protruding from the upper rim of the basin and a second end (shown by a dashed line inFIG. 12 ) connected with said plug by means of an articulatedlever mechanism 7. In such configuration, therotatable element 4, though shown inFIG. 12 , is not necessary to the system, and thedrain 2 can be any of those on the market. It is to note that thecontrol pin lever mechanism 7 which constitute a system completely similar to the one traditionally used for example in wash-basins of domestic bathrooms to open and close the wash-basin draining. - In
FIG. 13 , there is shown another embodiment of the invention wherein thesystem 102 comprises a lifting/lowering mechanism, that is the activation of theplug 12 that too comprises apin 601 having afirst end 602 provided with a gripping element consisting of a lever L having cam L1 rotatable on a plane vertical to the axis X-X of thewaste pipe 3. By acting on the lever L the plug is alternatively pressed so as to close an axially perforatedinner wall 330 of thepipe 3. Preferably, theplug 12 is a plastic disc having a central hole so as to be passed through by thesecond end 603 of thepin 601. Such second end ends with aplate 604 for thrusting the plug against the above saidinner wall 330 so as to close its axial hole (FIG. 13 ). - In
FIGS. 14 and 16 there are shown two more embodiment variants of the invention, wherein thesystems filter plug 8. In such configuration, the filter plug is directly connected with the intercepting and diverting system, that is with the means for diverting the flow of wastewater; in such solution the filter plug carries out, at the same time, the three functions of plug, of opening and of closing the gate-like diverting means. Agripping element 13A, similar to the one previously described, is fixed to the end of anaxial pin 660, while means for diverting the water flow are connected to thesecond end 661 of said pin. Said diverting means can be those previously described with reference to the gate-like device FIG. 14 , system 103) or can be a ball valve V (FIG. 16 , system 104) adapted to direct alternatively the water flow towards theprimary waste pipe 30 or towards thesecondary waste pipe 31 horizontally arranged on the same line orthogonal to the axis X-X of thewaste pipe 3. It is to note that if the diverting means are of the gate-like type, the twoperforated walls FIG. 3 shall be inverted, that is the movable wall will face downward while the fixed wall will be above said moveable wall, that is the fixed wall towards thedrain 2 and the movable wall towards theprimary waste pipe 30. -
FIG. 15 is a top view of adrain body 24 connected with the underneath portion (not shown) of thedrain 2 by means of two pins adapted to engage two corresponding throughcurved slots 25 formed diametrically opposed on said drain body. - In
FIGS. 17A-17D there is shown another embodiment. Thedraining system 105 comprises adrain 200 provided with afirst portion 201 for fixing on the bottom of the sink or wash-basin and asecond portion 202 adapted to protrude from the lower or outer surface of the bottom of said sink or wash-basin so as to connect itself with a watertight seal, a cylindricalwater waste pipe 340. Thepipe 340 extends about a rectilinear axis X-X and is provided with aprimary waste pipe 30 for the sewage system and asecondary waste pipe 35 for the recovery system. Means for diverting the wastewater flow are accommodated inside saidwaste pipe 340 and are selectively activatable so as to discharge water through said primary waste pipe or said secondary waste pipe. Said means are activatable by means of a control placed above the level of the basin bottom of the sink or of the wash-basin. - In particular, the
first portion 201 for fixing thedrain 200 consists of an externally threaded and flanged ring nut adapted to be inserted into the hole of the basin bottom (not shown) with the flange resting on a portion about said hole and with the threaded part protruding from the outer surface of the hole. Thesecond portion 202 comprises aflanged ring nut 203 having the inner surface provided with counter threading for the screw-like engagement with thefirst portion 201 so that the flanges of the respective ring nuts close sandwich-like a portion about the hole of the basin. Thesecond portion 202 is preferably en bloc with thewaste pipe 340. Theprimary waste pipe 30 and thesecondary waste pipe 35 are arranged along a common axis Z-Z generally orthogonal to the axis X-X of the waste pipe 340 (FIG. 17A ), preferably diametrically opposed. - The bottom of the
waste pipe 340 is closed and provided with aprotrusion 341 whereon it is engaged a rotating cylinder as explained later. - Preferably, the
second portion 202 of thedrain 200, thewaste pipe 340 and theprimary waste pipe 30 and thesecondary waste pipe 35 are realized en bloc. Alternatively, as shown in the section ofFIG. 17D , thewaste pipe 340 may be provided with anannular edge 342 radially protruding against which the threadedring nut 203 of thesecond portion 202 stops when screwed on thefirst portion 201 of thedrain 200. - The means for diverting the water flow comprise a
rotating cylinder 500 having a general cup-like configuration that replicates the shape of thewaste pipe 340 so as to be accommodated therein, preferably in a precise way. In particular, the cylinder comprises a closed bottom provided with afirst seat 501 recessed open outwardly and adapted to engage rotatably with theprotrusion 341 of thewaste pipe 340. Furthermore, thecylinder 500 comprises asecond seat 502 open in the opposite direction with respect to its bottom, so as to accommodate a pin for controlling the diverting means, as later explained. It is to note that both thefirst seat 501 and thesecond seat 502 are arranged along the axis X-X of thedrain 200 and of thepipe 340. - Preferably, the
second seat 502 comprises afirst portion 503 having a closed bottom with a polygonal, preferably triangular, cross section, and asecond portion 504 having a cylindrical section. - Advantageously, the
lateral wall 505 of therotating cylinder 500 comprises anaperture 506 for the flow of the wastewater from thedrain 200 to thewaste pipe 340. Such aperture may be composed of a series of windows separated by a filtering grid, as shown inFIG. 17D . - The
draining system 105 comprises also afilter basket 70 or strainer provided with a perimetral rim 71 (FIG. 17A-17D ) for resting on theannular rim 342 of thewaste pipe 340, a central hole (not shown) and with a series ofradial apertures 72 arranged about said hole (FIG. 17C ). - Preferably, a threaded
bushing 73 is screwed in thesecond portion 504 of thesecond seat 502 of thecylinder 500 and so as to accommodate a portion of a control pin, as later described. - The
draining system 105 further comprises aplug 800 for closing thedrain 200. The plug is completely conventional and it will not be further described. It is only to note that such plug comprises acontrol element 610 or pin provided with agripping element 611 for its operation. In particular, thepin 610 comprises afirst portion 612 adapted to be inserted in thebushing 73 and asecond portion 613 or end portion having a polygonal section, preferably triangular, so as to basically engage perfectly thefirst portion 503 of thesecond seat 502 of therotating cylinder 500. - Generally, then, the
draining system 105 also comprises a series of seal gaskets mounted between the various elements making it up. For example, as shown inFIGS. 17A and 17D , a gasket G is fixed by means of a suitable ring R on the outer surface of the bottom of theplug 800 in a completely conventional way. - The just described
system 105 advantageously allows to make constructively more compact and simplify the diverting means and the control means of said diverting means thus facilitating its operation. In fact, as shown inFIG. 17D , when thepin 610 is pressed towards the bottom of theplug 800, it occurs the draining closing in thedrain 200 thanks to the stop caused by the above said gasket G and by the relative ring R against thestrainer 71 so as to close itsapertures 72. On the contrary, when lifted, thepin 610 allows the water flow in thedrain 200 and, thanks to the rotation activated using the finger of one's hand on thegripping element 611 of thepin 610, it is controlled the rotation of therotating cylinder 500 so as to position itsaperture 506 in correspondence of theprimary waste pipe 30 towards the sewage system or of thesecondary waste pipe 35 towards the recovery system. It is to note that however also in the lowered position, that is when the plug is closed, the rotation can be activated all the same. In fact, it might happen that the recovery position remains active and the plug closed to allow the sink to be filled with soapy water for washing dishware. In this case, the opening of the plug would cause the soapy water to flow into the recovery system which would not be suitable for uses such as watering plants. Therefore the possibility to return to the sewage system having the plug closed allows to avoid such drawback. - An indicator (not shown) may be provided on the gripping element to see which is active whether the primary waste pipe or the secondary waste pipe. Of course, since the
rotating cylinder 500 is open only on one side of its lateral wall, it will not allow the water flow on the diametrically opposite wall, thus directing it only where wanted. - Moreover, there can be provided stop systems for the rotation of the
rotating cylinder 500, such as means 18 and 19 previously described which regulate the width of the rotation so as to make theaperture 506 overlap one between theprimary waste pipe 30 and thesecondary waste pipe 35. The system is then provided with overflow such as one similar to the one described with reference toFIG. 9 . - In
FIG. 18 , there is shown afirst variant 106 of the embodiment of the just described drainingsystem 105 and shown inFIGS. 17A-17D . The reference numbers in common refer to identical elements. In particular, therotating cylinder 500 differs from the cylinder of the system ofFIG. 17A for the presence of anannular band 506 arranged around the cylinder aperture and provided withgripping elements 507 through which it is possible to activate the rotation of therotating cylinder 500. Consequently, thepin 610 can be a traditional pin to activate the closing of theplug 800. The operation of the diversion of the water flow will be the same as the one described with reference to thesystem 104. - In
FIGS. 19A-19C , there is shown anembodiment variant 107 of thedraining system 105 ofFIGS. 17A-17D . The reference numbers in common refer to identical elements. In particular, thefirst seat 508 of the closed bottom of therotating cylinder 500 is shaped so as to accommodate atimer device 509 to re-position the rotating cylinder in the condition of the sewage system, that is that of draining water into the primary draining system. In practice, thetimer device 509 comprises for example an elastic element or spring 510 (FIG. 19C ) activatable by thecontrol pin 610 through the rotation of thecylinder 500 so as to be loaded. Moreover, saidelastic element 510 is connected to saidrotating cylinder 500 through a brake (not shown) that releases the elastic force on the cylinder in a continuous and regular way to make the cylinder rotate in a controlled and continuous way. Alternatively, the elastic force of the loaded spring is transferred to a snap mechanism (not shown) that at once makes therotating cylinder 500 rotate. Independently from how it rotates, the system comprises stop elements (not shown) such as those previously described. The operation of the diversion of the water flow will be the same as the one described with reference to thesystem 104. - In
FIG. 20 , there is shown athird embodiment variant 108 of thesystem 105 ofFIGS. 17A-17D . In this variant besides the elements in common referred to with the same reference number, thewaste pipe 340 has aprimary waste pipe 30, asecondary waste pipe 35 and athird waste pipe 350, preferably arranged along the circumference of the pipe at 120° one from the other. Thethird waste pipe 350 has the purpose of collecting water from the sink or wash-basin into a storage or decantation tank, for example, when its temperature is too high to be directly used for irrigation or when it contains food remains in suspension. It is to keep in mind that the arrangement of a plurality of waste pipes, for example more than two, can be envisaged also for the previously described systems with reference to the embodiments ofFIGS. 3-19 . The operation of the diversion of the water flow will be the same as the one described with reference to thesystem 105, with the possibility, as explained, to select through rotation three different waste pipes. - In
FIG. 21 , there is shown another embodiment wherein adraining system 109 basically comprises the same elements previously described and the parts in common with the previous embodiments are referred to with the same reference number. In particular, thesecond portion 613 of thepin 610 for controlling the means for diverting the water flow has a semi-cylindrical form so as to engage the correspondingfirst portion 503 of thesecond seat 502 of therotating cylinder 500 having a complementary section. Furthermore, thewaste pipe 340 comprises aperforated bottom 342 which is connected, preferably in a reversible way, to atank 900 for collecting the water that may potentially flow through the lateral walls of therotating cylinder 500 and of thewaste pipe 340 becoming stagnant on thebottom 342 of the same pipe, as it is neither drained in theprimary waste pipe 30 nor in thesecondary waste pipe 35 arranged diametrically opposed on the same plane of the axis Z-Z. The collectingtank 900 is also provided with a pipe fitting 901 to theprimary waste pipe 30 to make such stagnant water drain. The operation of diverting the water flow occurs as well through the rotation of therotating cylinder 500, as previously described. - In
FIG. 22 there is shown anotherembodiment variant 110 similar to the variant described with reference to thesystem 109 ofFIG. 21 , therefore the same reference numbers refer to identical elements. In particular thetank 900 for collecting stagnant water, which may ooze between therotating cylinder 500 and thewaste pipe 340, is made en bloc with thebottom 342 of the same pipe and thecorresponding waste pipe 902 is too en bloc with theprimary waste pipe 30, possibly separated by abaffle 903 which is a portion of the wall itself of theprimary waste pipe 30. - In
FIG. 23 there is shown afurther embodiment 111 alternative to the systems 108-110. In particular, the alternative consists in providing arotating cylinder 550 provided with twoapertures apertures waste pipe 345 comprises aprimary waste pipe 30 and asecondary waste pipe 35 positioned at two different heights on its lateral wall, preferably the primary waste pipe is at least partially positioned at the bottom of the pipe and more preferably having an inclined part departing with respect to the lateral wall of the same pipe. Furthermore, theprimary waste pipe 30 and thesecondary waste pipe 35 are preferably positioned at 180° one from the other. The operation of the diversion of the water remains the same as previously described. - In
FIG. 24A there is shown a further embodiment wherein adraining system 112 comprises adrain 210 provided with afirst portion 211 for fixing on the bottom of the sink or wash-basin and asecond portion 212 adapted to protrude from the lower or outer surface of the bottom of said sink or wash-basin so as to connect with a watertight seal with a cylindricalwater waste pipe 360. Thepipe 360 extends about a rectilinear axis X-X and is provided with aprimary waste pipe 30 for the sewage system and asecondary waste pipe 35 for the recovery system.Means 560 for diverting the flow of wastewater are accommodated inside saidwaste pipe 360 and are selectively activatable so as to discharge water through said primary waste pipe or said secondary waste pipe. Said means 560 are activatable through acontrol 611 positioned above the level of the basin bottom of the sink or of the wash-basin. - In particular, besides the element in common with the previous embodiments which have the same reference number, the diverting means 560 are preferably a hollow rotating cylinder extending rectilinearly along the axis X-X and comprising a first annular
flanged end 561, provided with agroove 562 for accommodating a gasket (not shown), a secondcylindrical end 563 and anintermediate portion 564, cylindrical as well. Theintermediate portion 564 comprises in its turn afirst aperture 565 axially aligned with asecond aperture 566 formed in correspondence of the second end. Axially, the cylinder comprises arectilinear shaft 567 provided with first bayonet means 568 for the reversible coupling on the bottom of the waste pipe, as later explained, and aseat 569 for the engagement of the bushing 73 (FIG. 24C ). Saidseat 569 is divided into a first part 569A for the reversible engagement with said bushing, in a completely conventional way, and into a second part 569B for the engagement with theend portion 613 of the pin orrotating element 610. - On the contrary, the
waste pipe 360 comprises afirst portion 361, preferably en bloc with thesecond portion 212 of saiddrain 210, and asecond portion 362, preferably separated from the first portion and connectable thereto with a watertight seal by means of rapid connections such as bayonet coupling or screwing. Furthermore, thefirst portion 361 of thepipe 360 comprises thesecondary waste pipe 35, while thesecond portion 362 comprises theprimary waste pipe 30, saidprimary waste pipe 30 andsecondary waste pipe 35 are on two staggered planes and preferably diametrically opposed. Therefore, the rotation given to therotating cylinder 360 by thecontrol 611 through thepin 610 by means of the elements previously described, advantageously allows to select either thesecondary waste pipe 35 or theprimary waste pipe 30 alternatively thanks to the arrangement of thefirst aperture 565 and of thesecond aperture 566 axially aligned and to the corresponding pipes which on the contrary axially misaligned. - Furthermore, the
second portion 362 of thewaste pipe 360 comprises on its bottom second bayonet means 363 (FIG. 24D ) adapted to cooperate with said first bayonet means of theshaft 567 of therotating cylinder 560. - Now, the assembly of the
system 112 requires the screwing of thebushing 73 in theseat 569 of theshaft 567 of therotating cylinder 560, then thecontrol 610, bearing theplug 800 as usual with itsportion 612, is inserted in thebushing 73 and with thesecond portion 613 precisely engages the second portion 569B of theseat 569 of theshaft 567 of the rotating cylinder 560 (FIGS. 24C and 24E ). At this point, the rotating cylinder thus arranged can be bayonet fitted in thesecond part 362 of thewaste pipe 360. Thanks to the above said engagement of the control element on theshaft 569 of therotating cylinder 560 it is possible to rotate the same cylinder in the above said positions. - In the closing position of the
system 112, as shown inFIGS. 24C and 24E , both thefirst aperture 565 and thesecond aperture 566 face towards the closed lateral wall respectively of thefirst portion 361 and of thesecond portion 362 of thewaste pipe 360. Moreover, the first 568 and second 363 bayonet means respectively of therotating cylinder 560 and of thewaste pipe 360 are disengaged so as to allow the extraction of the same rotating cylinder from the pipe for the maintenance and cleaning of the system. On the contrary, when for example the system is in the position of the sewage system, as shown inFIGS. 24G and 24I , or in the position of the recovery system, the bayonet coupling does not allow the extraction of the above said cylinder so as to avoid unwanted water leaks along the whole draining system. - In
FIGS. 25A-25D there is shown a further embodiment wherein adraining system 113 comprises adrain 220 provided with afirst portion 221 for fixing on the bottom of the sink or wash-basin and asecond portion 222 adapted to protrude from the lower or outer surface of the bottom of said sink or wash-basin so as to connect with a watertight seal to a cylindricalwater waste pipe 370. Thepipe 370 extends about a rectilinear axis X-X and is provided with aprimary waste pipe 30 for the sewage system and asecondary waste pipe 35 for the recovery system.Means 570 for diverting the wastewater flow are accommodated inside saidwaste pipe 370 and are selectively activatable so as to discharge water either through the primary waste pipe or through the secondary waste pipe. Said means 570 are activatable by means of acontrol 611 positioned above the level of the basin bottom of the sink or wash-basin. - In particular, besides the elements in common with the previous embodiments which have the same reference number, the diverting means 570 are preferably a first truncated cone-shaped
element 571 and asecond element 572 both hollow. Thefirst element 571 has an open major base facing the axialprimary waste pipe 30 and a closedminor base 574 facing the opposite with respect to the major base (FIGS. 25C and 25D ). The major base is surrounded by aflange 575 for fixing on the inner wall of thewaste pipe 370. The minor base is instead provided with anaxial pin 576 protruding towards the outer part of the first cone-shapedelement 571, preferably surrounded byelements 577 for rotating coupling (FIGS. 25C and 25D ) with thesecond element 572.Such elements 577 can be elements such as rotating bearings. Advantageously, the lateral wall of thefirst element 571 is provided with an opening W for draining water into thesecondary waste pipe 35, as later described. - The
second element 572 comprises an axial truncated cone-shapedportion 578 preferably surrounded by a peripheral cylindrical portion ormantle 579. Theaxial portion 578 is complementary to thefirst element 571 so as to substantially fit it precisely. Consequently, also the second element comprises an open major base and a closed minor base. The major base comprises aflange 580 for the connection with thecylindrical mantle 579. Further, the mantle surrounds axially only a part of theaxial portion 578 and only awall 581 extends axially beyond the mantle towards the minor base of the same axial portion. From the minor base, then prolongs aseat 582 for accommodating thecontrol pin 610 of the rotation and therelated bushing 73, analogous to those previously described. Furthermore, also the lateral wall of theaxial portion 578 comprises an aperture W1 (FIGS. 25A and 25D ) coinciding with the aperture W of thefirst element 571. It is to keep in mind that the aperture W1 on the lateral wall of theaxial portion 571 is radially staggered with respect to thewall 581 of thecylindrical mantle 579, preferably staggered by about 90°. - The
waste pipe 370 is basically a cylindrical pipe extending rectilinearly along the axis X-X and comprises an axialprimary waste pipe 30 and a radialsecondary waste pipe 35, orthogonal to the axis X-X and formed in the proximity of thedrain 220. - Consequently, the
system 113 can operate in a first mode wherein thefirst element 571 of themeans 570 for diverting the water flow is fixed inside thewaste pipe 340 with its major base downstream thesecondary waste pipe 35 and the minor base basically in correspondence of saidsecondary waste pipe 35. The aperture W of the first element is preferably oriented at 90° with respect to saidsecondary waste pipe 35. Thesecond element 572 of themeans 570 for diverting the water flow is rotated on thefirst element 571 so as to have the aperture W1 overlapped with the aperture W. In this position, thewall 581 of thecylindrical mantle 579 of thesecond element 572 closes thesecondary waste pipe 35, therefore causing the water to flow through said apertures W and W1 of the first divertingmeans 571 and of the second diverting means 572, which are overlapped and then in order to directly flow into theprimary waste pipe 30 through theaperture 573 of the major base of thefirst element 571. - Conversely, by acting on the
control 611, thepin 610 causes thesecond element 572 to rotate onto thefirst element 571 preferably by 90° so as to bring the aperture W1 of the second element radially staggered with respect to the aperture W of the first element. At the same time, thewall 581 of thesecond element 572 positions itself away from thesecondary waste pipe 35. Consequently, the water from thedrain 220 cannot flow through the two apertures W1 and W, therefore it cannot flow through theaperture 573 of thefirst element 571 to drain into theprimary waste pipe 30. On the contrary, flows freely into thesecondary waste pipe 35. - In
FIGS. 26A-26C there is shown a further embodiment wherein themultiple draining system 114 comprises adrain 230 provided with afirst portion 231 for fixing on the bottom of the sink or wash-basin and asecond portion 232 adapted to protrude from the lower or outer surface of the bottom of said sink or wash-basin so as to connect with a watertight seal with a cylindricalwater waste pipe 380. Thepipe 380 extends about a rectilinear axis X-X and is provided with a plurality ofpipes Means 583 for diverting the wastewater flow are housed inside saidwaste pipe 380 and are selectively activatable so as to discharge the water through one of said plurality of pipes. Said means 583 are activatable through acommand 610 located above the bottom level of the sink or wash-basin. - In particular, besides the elements in common with the previous embodiments which have the same reference number, the water diverting means 583 have preferably a cup-like shape comprising a
closed bottom 584 and provided with aseat 585 for the engagement of thepin 610 for controlling the rotation, by the insertion of thebushing 73, and aseat 586 for the rotating engagement with a rotation axis of the bottom of thewaste pipe 380. In particular, the lateral wall of thecup 583 comprises an aperture W2 located in the proximity of the bottom 584 for diverting the water flow into one of said plurality of pipes (FIG. 26C ). - The
waste pipe 380 too has preferably a cup-like shape so as to be complementary to the above saidwater diverting means 583. In fact, said means 583 are rotatably and substantially precisely accommodated inside said waste pipe by means of the engagement of arotating axis 587 of the bottom of the pipe with the above saidseat 586 of the diverting means, preferably a bayonet coupling as in the foregoing. Advantageously, the pipe comprises a plurality ofpipes primary waste pipe 30 for the sewage system, asecondary waste pipe 35 for recovery water for domestic use or for irrigation and athird pipe 36 for other uses or for collecting into a tank (not shown) for storage, cooling or decantation before a subsequent domestic or irrigation use. Furthermore, similarly to what envisaged for thesystem 111 ofFIGS. 23A-23D , also in this system there may be provided the sewage pipe located starting from the bottom of the cup of thewaste pipe 380 so as to let out possible remaining water. - The operation of the just described
system 114 is very simple and intuitive since, as in the foregoing, through thecontrol 611 it is possible to rotatably activate thepin 610 which transfers the motion to thecup 583 in order to select the desired one of said plurality of pipes causing the aperture W2 of the same cup to overlap exactly theprimary waste pipe 30, thesecondary waste pipe 35 or thethird pipe 36. - Furthermore, the compactness and constructive simplicity of the present solution allow an easy assembly, simple maintenance, low production costs, besides a minimum bulk in the lower part of the sink.
- In
FIG. 27 there is shown a different embodiment wherein themultiple draining system 115 comprises adrain 240 provided with afirst portion 241 for fixing on the bottom of the sink or wash-basin A and asecond portion 242 adapted at protruding from the lower or outer surface of said sink or wash-basin so as to connect with a watertight seal with cylindricalwater waste pipe 480. Thepipe 480 extends about a rectilinear axis X-X and is provided with a plurality ofpipes Means 683 for diverting the wastewater flow are accommodated inside saidwaste pipe 480 and are selectively activatable so as to discharge water through one of said plurality of pipes. Said means 683 are activatable by means of acontrol 610 located above the bottom level of the basin of the sink or of the wash-basin and lying on said axis X-X. - In particular, besides the elements in common with the previous embodiments which have the same reference number, the water diverting means 683 (
FIG. 28 ) preferably have a cylindrical shape with alateral wall 684, a bottom 685 and anaperture 686 axially opposed to said bottom. On the lateral wall there is at least ahole 687 for the wastewater flow formed in the proximity of the bottom 685. Preferably, there are afirst hole 687 and asecond hole 687 radially staggered by 90° and located at the same level. Awindow 688 is then formed in the proximity of theaperture 686. As later described, said holes have the purpose of directing wastewater either towards the sewage system or towards the recovery system, while thewindow 688 acts as an overflow and positions itself in correspondence of a similar window (not shown) formed on thewaste pipe 480 this too connected to the conventional overflow hole (not shown) of the basin. - The bottom 685 is provided with a through hole 689 (shown in
FIG. 29B ) in continuity with aninner sleeve 690 whose cavity is such that it fits on a pin for the rotation of the waste pipe, as later explained. From the free edge of the sleeve extendfirst elements 691 for the engagement with second engaging elements 400 (FIG. 28 ), said second elements being connected to a rotation control in order to control the rotation of the water flow diverting means 683, as described later. Preferably, the firstengaging elements 691 are constituted by a plurality of walls against which the secondengaging elements 400 engage themselves pushing them to rotate about the axis X-X. In particular, the walls are three and are separated one from the other by specific spaces 692 (only one shown inFIG. 28 ) between which saidsecond elements 400 engage themselves. The spaces are preferably arranged on a circumference and spaced by 120°. - In particular, as shown in
FIGS. 29A-29B , the cross section of the inner cavity of thesleeve 690 shows a first narrow andconstant section 693 farther from thebottom 685 of thecylinder 683 and a secondenlarged section 694 closer to the bottom 685. Saidsecond section 694 comprises a firstradial extension 694A having a radius greater with respect to a secondannular extension 694B. In this way, twocircumferential steps 695 are formed on the inner wall of the sleeve that constitute two stop points of the rotation of therotating cylinder 683 on thecylindrical pipe 480. - The water diverting means 683 are accommodated inside the water waste pipe 480 (
FIG. 28 ). This pipe has preferably a cylindrical form complementary to that of said diverting means. In particular, the pipe comprises alateral wall 481 provided with holes communicating with a plurality of water waste pipes. Preferably the pipes are two: a pipe for recoveringwater 35 and apipe 30 for the sewage system. Further, the two pipes are diametrically opposed. From thebottom 482 of the cylindrical pipe raises ahollow pin 483 whose cavity constitutes the fixing seat of thebushing 73 and on whose outer wall rotatably fits thesleeve 690 of therotating cylinder 683. Preferably, at the base of saidseat 483 there is anannular seat 484 for accommodating anelastic element 509 such as the spring described in the foregoing. Furthermore, the base of theseat 483 has in its cross section a radial tooth 487 (FIG. 30B ) adapted to engage the above said firstradial extension 694A of thesecond section 694 of theseat 690 of thewater diverting means 683. It is also to note that the bottom 482 is advantageously inclined with the incline towards either one of the two waste pipes of the sewage system or of the recovery system in order to avoid water stagnations (FIG. 34B ). - The
aperture 485 of the pipe wherefrom the diverting means are inserted is surrounded by aflange 486 provided with a series ofribs 488 for holding an O-ring gasket O1 (FIG. 27 ). - The water diverting means 683 are made to rotate inside the
pipe 480 by means of an enbloc control 620 with a gripping knob 621 (FIG. 27 ). In turn, thecontrol 620 comprises afirst portion 622 extending axially from the knob and locks together with asecond portion 623, the latter being such that it reversibly locks inside saidbushing 73. Between thecontrol 620 and thebushing 73 there are locked together aclosing plug 810 with the respective gasket 811 (FIG. 27 ) and the above saidsecond elements 400 for the engagement with the firstengaging elements 691 of the rotating cylinder of thewater diverting means 683. - In particular, as shown in
FIGS. 31A-31C , thesecond elements 400 preferably comprise a plurality offeet 402 which engage thefirst elements 691 of therotating cylinder 683. The feet are preferably three and extend in correspondence of the edge of a firstflat face 403 of acircular base 401 and perpendicular to the latter. Furthermore, the three feet are arranged on the base at 120° one from the other. More preferably, they generally show a hooked cross section so as to engage an edge of said walls defining the above saidspace 692 between thesame walls 691 of therotating cylinder 683. On thesecond face 404 of thecircular base 401 protrudes atooth 405 adapted to engage acorresponding hole 406 formed on the plug 810 (FIG. 32 ). Centrally, thebase 404 is crossed by a throughhole 406 for locking together with the above saidfirst portion 622 of thecontrol 620. - The
second portion 242 of the drain (FIGS. 33A-33C ), also called strainer, comprises a perforated bottom, having preferably three circumferential holes extending for about 120° shaped as an arc of a circle so as to allow the rotation of the above said threefeet 402 of thesecond elements 400. Said holes then surround acentral hole 811 for engaging thefirst portion 622 of thecontrol 620, in a completely conventional way. - The assembly of the just described draining
system 115 envisages a first step wherein therotating cylinder 683 is fitted inside thewaste pipe 480. When is inserted, thesleeve 690 of the rotating cylinder is fitted on the fixingseat 483 of thebushing 73 in thewaste pipe 480 so as its firstradial extension 694A of thesecond section 694 of thesleeve 690 engages with theradial step 487 of theseat 483 of thebushing 73 of thepipe 480 thus realizing a bayonet coupling. It is to note that the length of the first annular extension is such that it allows a rotation by 90° of the radial step, and hence of the rotating cylinder between the twostop points 695 of the same extension (FIGS. 29B-30B ). In particular, the arrangement of the firstannular extension 694A and of the correspondingannular step 487 are such as to selectively direct one of the twoapertures 687 of therotating cylinder 683 towards either thesewage system 30 or towards therecovery system 35, while the other one is closed by thelateral wall 481 of thewaste pipe 480. - The
control element 620 is assembled by locking together in succession theplug 810 on thefirst portion 622, then thegasket 811 of the plug, the secondengaging elements 400 so as insert theirtooth 405 into thehole 406 of the plug and finally thesecond portion 633 of the control element. - The fixing
bushing 73 between the control element, thedrain 240, the water diverting means 683 and thewaste pipe 480, is blocked in theseat 483 of the same pipe and, finally, the control element assembled as above, is reversibly fitted in thebushing 73 with thesecond portion 623 by means of conventional elastic elements. The bushing blocking can be made by locking or by means of a screw-like engagement (FIG. 34B ). - The advantage of the just described draining
system 115 lies in the constructive simplicity which requires few modifications with respect to the traditional systems. Practically, the elements which make up the control and the plug are the same as the conventional ones, while the rotation means are constituted by a cylinder which accommodates therein a conventional drain and that, in turn, is accommodated inside a very compact waste pipe. Furthermore, the rotation mechanism comprises an engaging element for the rotation of the cylinder provided with a simple and efficient structure for transmitting the rotation given by the control element to the cylinder. - In fact, as shown in
FIG. 35 , thesystem 115 is arranged in the sewage system condition wherein one of the twoapertures 687 of therotating cylinder 683 is in communication with thesewage waste pipe 30, while theother aperture 687 is closed by thelateral wall 481 of thewaste pipe 480. - As shown in
FIG. 36 , by rotating theknob 621 of thecontrol 620 for example in the clockwise direction by 45°, bothapertures 687 of therotating cylinder 683 are closed by thelateral wall 481 of thewaste pipe 480. Therefore, in this position, advantageously, a further safety is achieved in case fluids or small object might fall in the sink as they would not flow into the waste pipe. Moreover, in this way the communication with the draining system can be closed thus preventing unwanted smells from surfacing. - As shown in
FIG. 37 , a further rotation of theknob 621, for example in the same clockwise direction by 45°, allows one of theapertures 687 to communicate with therecovery pipe 35, while the other aperture is closed by thesame wall 481 of thewaste pipe 480. -
FIG. 38 is an exploded view of an embodiment similar to the previous one, therefore the identical elements have the same reference number and will not be described any further. In particular, thesystem 116 comprises water diverting means 630 that preferably are made up of a rotating disc having twoholes 631 for alternatively draining to the sewage or to the recovery systems (FIG. 39 ), preferably at 90° in the proximity of the circumference of the disc. - As also shown in
FIGS. 40A-40D , thedisc 630 shows afirst surface 632 and asecond surface 633 which are opposite and generally flat crossed by said twoholes 631 arranged in the proximity of the circumference and a centralengaging hole 634 with a pin for rotating the waste pipe and the fixing seat of thebushing 73. In particular, from thefirst surface 632 and about thecentral hole 634 raises asleeve 635 similar to thesleeve 690 described with reference to thesystem 115. Said sleeve has thereforefirst elements 636 the same as thefirst elements 691 previously described and separated by spaces 636A between which engage the previously describedsecond elements 400. - Furthermore, from the
first surface 632 stand two hollow towers 637 (FIG. 40B ), preferably having an arc of a circle section, diametrically opposed. In particular, one tower is located between two drainingholes 631. Said towers have their inner cavity in communication withcorresponding holes 638 opening on thesecond surface 633 of the disc (FIG. 40C ). - It is to note that also the section of the
sleeve 635 is the same as the one of thesleeve 690 previously described (FIG. 40D ). - The
draining system 116 further comprises awaste pipe 530 provided with a firstcylindrical portion 531 and a second discoid portion 532 (FIG. 38 ). The seconddiscoid portion 532 comprises a firstopposed surface 533 and asecond surface 534, both generally flat (FIG. 41A-41C ). From the peripheral edge of thefirst surface 533 raises anannular band 535 provided with a groove 536 (FIG. 39 ) for accommodating a gasket O2 of the O-ring type (FIG. 38 ). Furthermore, from thefirst surface 533 raises centrally aseat 537 for fixing abushing 73, identical to theseat 483 described for thesystem 115. Also the section of saidseat 537 is identical to the one previously described. Preferably, theseat 537 has an aperture 538 (FIG. 41B ) that allows to discharge water in case it might ooze inside the same seat so as to be discharged either into thesewage waste pipe 30 or into therecovery waste pipe 35 according to the position of the diverting means. Further, the firstdiscoid portion 532 has two throughholes 539 diametrically opposed. Each one of these holes communicate respectively with either thesewage waste pipe 30 or with therecovery waste pipe 35, such pipes extending from thesecond surface 534 of said second discoid portion 532 (FIG. 41B ). - Preferably, one of the two
holes 539 and that is the one connected to therecovery waste pipe 35, is surrounded by agroove 540 adapted to accommodate an O3 gasket (FIG. 38 ). - The
first portion 531 of thewaste pipe 530 has a cylindrical sleeve-like shape with aflange 541 formed in the proximity of a firstaxial aperture 542 radially facing inward (FIG. 42B ). Preferably, the flange comprises one ormore grooves 543 for the engagement with an O1 seal gasket. In correspondence of the secondaxial aperture 544, thefirst portion 531 comprises a flaring 545 whose peripheral edge is such that it engages with the peripheral edge of theannular band 535 of thefirst portion 531 of thepipe 530 with the insertion of the above said O2 gasket. - The assembly of the just described draining
system 116 requires the preparation of the plug by means of locking together thecontrol element 620 with theplug 810, with the secondengaging elements 400 inserting thegasket 811 and with thefirst portion 622 of the control element, as previously described. - The
sleeve 635 of the diverting means 630 is fitted on theseat 537 of thefirst portion 532 of thewaste pipe 530 so as to insert thesecond surface 633 of the diverting means into the space defined by theannular band 535 of the same second portion. As previously, to do so, the sections of thesleeve 635 and of theseat 537 must be aligned so as to realize the bayonet coupling. Once the diverting means 630 have been arranged on thefirst portion 532 of thewaste pipe 530, thesecond portion 531 of the same pipe can be mounted through the above said engagement between the peripheral edge of the flaring 545 of thefirst portion 531 and the peripheral edge of theannular band 535. Preferably, a retaining ring R1 (FIGS. 38, 44-46 ) is fitted in the space defined between the seat or pin 537 for the rotation of the diverting means 630 and thesleeve 635 of said means so that from one side it engages a circumferential groove (not shown in the drawings) at the base of theseat 537 and on the other side it basically rests on a flange (not shown in figures) inside said sleeve. In particular, the ring has a cut typical of the commercial rings called seeger rings. - At this point, the
bushing 73 can be fixed in theseat 537 and the above said assembly made up ofcontrol element 620/plug 810 together withgasket 811/second engaging means 400 can be fixed inside thewaste pipe 530 with the insertion of thedrain 240. - The operation of the
system 116 is similar to the one previously described. In fact, rotating theknob 621 of thecontrol element 620, it is achieved the rotation of themeans 630 for diverting the water flow thanks to the above said engagement of the secondengaging elements 400 with thewalls 636 of thesleeve 635 of the same diverting means. - The above said rotation involves, as shown in
FIG. 44 , the positioning along the axis X-X of one of the twoholes 631 in correspondence of one of the twoholes 539 of thefirst portion 532 of thewaste pipe 530, which in turn is in communication with therecovery waste pipe 35, while theother hole 631 will be covered by thefirst surface 533 of said first portion. - It is to note that in this position, should the recovery pipe be connected with a full storage tank and the water should go back inside the same pipe up to the drain 240 (dashed line of
FIG. 43B ), the aperture on top of eachhollow tower 637 would act as an overflow making the water flow into a space between thesecond surface 633 of the diverting means 630 and thefirst surface 533 of thefirst portion 532 of thewaste pipe 530. Oozing, such water would trickle into theother aperture 539 of the first portion which is in communication with thesewage waste pipe 30. - As in the foregoing, by further rotating the knob clockwise it is achieved the closing of the waste pipe 530 (
FIG. 45 ) and a further rotation still clockwise would bring the system into sewage position (FIG. 46 ). Such positions are completely similar to those previously described with the difference that they take place so as to make the holes coincide along the axis X-X of the system in order to make water flow from the drain to either the recovery waste pipe or to the sewage waste pipe. - With reference to
FIGS. 47-50 , there is shown a variant of the embodiment described with reference to thesystem 116 of theFIGS. 38-46 . Equal elements have the same reference number and therefore they will not be described. In particular, thedraining system 117 differs from the previous one since the second engaging means for the rotation of themeans 630 for diverting wastewater flow, comprise afirst portion 421 basically corresponding to thesecond elements 400 previously described. In fact, as shown inFIGS. 49A-49B , thefirst portion 421 is provided with threefeet 422 of which one has a sectional form different from the sectional form of the other two so as to make more immediate the orientation of the engagement with a second portion of said engaging elements. For example, as shown, two feet have a hook-like section as the feet of the previously describedelements 400 while the third one has an elliptical section. - The
second portion 423 of the second engaging rotating elements, as shown in particular inFIG. 50 , comprises a base 424 preferably having a perforated disc-like shape as a kind of filter. The base also comprises acentral hole 425 for the passage of thecontrol element 620 and threehollow feet 426 having a section complementary to thefeet 422 of thefirst portion 421 so as to accommodate the same therein. - The assembly is substantially the same as the one described with reference to the previous embodiment, with the sole variant that between the
drain 240 and the diverting means 630 there is inserted thesecond portion 423 of the second engaging rotating elements so that the base 424 acts as a filter (FIG. 48 ). Furthermore, a threaded ring D is screwed on thebushing 73 to block saidsecond portion 423 at a preset distance from thedrain 240 but anyway allowing both its rotation and its function as a filter for possible dirt, without hindering the water flow. -
FIG. 51 shows asystem 118 wherein the reference numbers equal to those of the previous embodiments show equal elements which will not be further described. In general thesystem 118 comprises, it too, just like theaforementioned systems water waste pipe 590 comprising a firstdiscoid portion 592 and a second sleeve-like portion 591. - In particular, the diverting means 650, as better shown in
FIGS. 52A-52B , comprise a flat and preferably disc-like base 651 having afirst surface 652 and asecond surface 653 opposed to the first. Thefirst surface 652 has two concentric and axially perforatedprotrusions 654. A firstcentral hole 655 having a polygonal shape, preferably triangular, is surrounded by a series ofapertures 656, preferably three of them, shaped as an arc of a circle. Twosecond holes 657 are arranged in correspondence of the perimeter of thebase 651 and spaced by about 90°, one for the sewage system and one for the recovery system. Athird hole 658 opens on the second face 653 (FIG. 52B ) and is in connection with ahollow tower 659 which raises from thefirst surface 652 and it has an open top communicating with said third hole. Preferably thetower 659 is located at about 135° from bothsecond holes 657. - As shown in
FIG. 52B , the twoconcentric protrusions 654 internally comprise afirst section 670 and asecond section 671 in the shape of an arc of a circle having a different radius so as to form twostop points 672 for the rotation on thesecond portion 592 of thewaste pipe 590, as later described. - The
second portion 591 of thewaste pipe 590 corresponds to thesecond portion 531 of thewaste pipe 530 previously described with reference to the system 117 (FIG. 51 ). - The
first portion 592 of thepipe 590 comprises afirst surface 593 opposed to a second surface 594 (FIG. 53 ). From the peripheral edge of thefirst surface 593 raises anannular band 595 identical to the one described with reference to thesystem 117. Further, still from saidfirst surface 4 raises a fixingseat 596 of thebushing 73. Said seat preferably comprises anaperture 597 at the base for draining water should it ooze therein. Twoholes annular band 595.Such holes recovery waste pipe 35 and thesewage waste pipe 30. - Advantageously, the
first surface 593 comprises aportion 593A inclined from thehole 510 communicating with therecovery pipe 35, towards the hole of thesewage pipe 30 so as to make probable stagnant water fall, due to gravity, onto said first surface towards the sewage pipe. - In accordance with a particular embodiment, the
seat 596 comprises abase 598, with saidaperture 597, wherefrom it raises a plurality offeet 599 adapted to firmly engage corresponding grooves formed on a connectingelement 430 between thebushing 73 and thefirst portion 592 of thewater waste pipe 590. In fact, as shown inFIG. 54 the connectingelement 430 is preferably in the form of an internally threaded nut so as to engage the counter thread of thebushing 73 and provided with an outer surface having saidgrooves 431. It is to note that anyway thebase 598 of thefirst portion 592 of thepipe 590 has two peripheral sections having a diameter so as to receive the above said firstperipheral section 670 and secondperipheral section 671 of theconcentric protrusions 654 of the water diverting means 650 so as to realize a bayonet coupling. - The
draining system 118 further comprises a control element 690 (FIG. 51 ) substantially similar to the one described for thedraining system 105. In particular, thecontrol element 690 comprises afirst portion 691 provided with agripping knob 692 and a pin for locking in asecond portion 694 for reversibly fixing inside thebushing 73. Thesecond portion 694 comprises anend 695 for the engagement with thepolygonal hole 655 of thewater diverting means 650. Preferably, such end has a triangular section which couples with the triangular section of thepolygonal hole 655. As in the foregoing, thepin 693 and thesecond portion 694 of thecontrol element 690 can be realized en bloc and have on the outer surface elastic elements for a reversible radial engagement inside thebushing 73 to allow the conventional closing of water draining by means of thedrain 240 through theplug 810. It is to note that in this embodiment theplug 810 does not comprise any supplementary hole besides the conventional radial holes, therefore it can be found on the market and it does not need any adjustments. - The assembly of the just described
system 118 is similar to that of thesystem 117 and requires to lock together thefirst portion 691 of the control element, theplug 810 withgasket 811 andsecond portion 694 still of thecontrol element 694. Then, the water flow diverting means 650 are fitted on theseat 596 of thefirst portion 592 of thewaste pipe 590 so that the respective first 670 and second 671 sections of theconcentric protrusions 654 couple with the section of thebase 596 of thefirst portion 592. Now, the connectingelement 430 is fastened to theseat 596 of thefirst portion 592 by fitting thefeet 599 with thegrooves 431. At this point, thebushing 73 is screwed inside the connectingelement 430 inserting thedrain 240 with the respective O1 gasket. - Other gaskets can be provided and placed in the same points as previously described.
- Note that assembled as such, the
system 118 has the connectingelement 430 fixed at a certain distance from the surface of theconcentric protrusions 654 to allow the free rotation of the water flow diverting means 650 (FIG. 55 ). - As shown in
FIG. 56A , in a first operating condition, thecontrol 691 is in the recovery system position. In fact, one of the twosecond holes 657 of the wastewater flow diverting means 650 is in communication with therecovery waste pipe 35. On the contrary, the other one of the twoholes 657 is covered by thefirst surface 593 of thefirst portion 592 of thewaste pipe 590. - By rotating the
control 690 for example by 45° clockwise by means of itsknob 692, theend 695 pushes into rotation the diverting means 650 positioning bothsecond holes 657 to close on thefirst surface 593 of thefirst portion 592 of the waste pipe 590 (FIG. 56B ). - By rotating again the control still for example by 45° clockwise, one of the two
second holes 657 positions itself in communication with thesewage waste pipe 30 while the other one is closed by said first surface of the first portion of the waste pipe. - The advantage obtained with this last embodiment lies in the fact that the rotation control is essentially the same as a conventional plug. In fact, the circular portion with radial apertures does not need to be perforated in order to lock together with the tooth of the rotation means 400 described with reference to the
embodiments feet 599 of theseat 596 which is part of the waste pipe. Therefore, besides the diverting means 650, it will be sufficient to arrange the waste pipe with a second portion having a very simple shape such as that of a sleeve and a first generally discoid portion with the above said seat for the fixing bushing with the drain. - This means that the entire construction and production are simplified with resulting lower costs.
- Furthermore, as schematically shown in
FIGS. 51 and 56A-56C , thesystem 118 can comprise, it too, aspring 509 or elastic element to control the slowed return of the diverting means for example from the recovery system position to the sewage system position. Such mechanism, as already explained, has the function of preventing water containing soaps or other substances, which would not be suitable for reuse such as for watering plants and/or gardens, from flowing into the recovery system. Thespring 509 can be accommodated in a bottom portion B of thesecond portion 592 of thewaste pipe 590 and associated to a pin P for the connection with theend 695 of thecontrol 690. Moreover, a flat gasket O5 can be inserted between thefirst portion 592 of thewaste pipe 590 and the divertingmeans 650. Such gasket is perforated only in correspondence of theholes second portion 592 to ensure water-tightness when one of thesecond holes 657 of the diverting means 650 is not aligned with therespective hole - In
FIG. 57 , thesystem 119 for discharging water from sinks or wash-basins is similar to the previously describedsystem 118 with reference toFIGS. 51-56 , therefore the same reference number will refer to equal elements and will not be described any further. In particular, thesystem 119 comprisesmeans 640 for diverting wastewater flow having the shape of a cylindrical container. - As better shown in
FIGS. 58A-58C , the diverting means 640 have acircular bottom 641 and an annularlateral wall 642. The bottom comprises twofirst holes 643 located in the vicinity of its circumference and preferably spaced by 90°. These first holes are connected, as either with the recovery waste pipe or with the sewage waste pipe as later explained. Twosecond holes 644 are located along said circumference and are diametrically opposed. Moreover, the second holes communicate each with a corresponding tower 645 (only one is shown inFIG. 58D ) for discharging overflow water identical to the overflow towers previously described. - Two
concentric protrusions 646 axially perforated and overlapped raise from the bottom 641. A firstcentral hole 647 of the protrusions has a section such as to accommodate precisely the end of the control, preferably having a polygonal section and more preferably a triangular section. The central hole is then surrounded by a series ofapertures 648 shaped as an arc of a circle, preferably three. - Advantageously, the inner surface of the bottom 641 comprises an inclined ramp-like portion 649 (
FIG. 58C ). Preferably, saidportion 649 has the higher point far from the first twoholes 643 and an inclined ramp towards the same holes so as to facilitate the elimination of possible stagnant water on the same bottom (FIGS. 58B and 58C ). Note that such ramp can be provided also for the previous embodiments whose diverting means are made up of cylinders, cup-like containers and rotating discs. - The inner section of the two
concentric protrusions 646 has the same trend as the one described with reference in particular to thesystem 118. Therefore, such section comprises twopoints 646A of the rotation stop on the second portion of the waste pipe, as later described. - The
waste pipe 520 of thesystem 119 comprises asecond portion 521 and a first portion 522 (FIG. 57 ). Thesecond portion 521 basically corresponds to thesecond portion 591 of thesystem 118. The first portion 522 (FIGS. 59A-59B ) has a general structure substantially identical to thefirst portion 592 of thesystem 118. Preferably, this first portion comprises anannular seat 523 located between theholes recovery waste pipe 35 and thesewage waste pipe 30, as for theholes embodiment 118. The annular seat is such as to accommodate a corresponding seal gasket O4 (FIG. 57 ) when either one or the other of the twoholes 642 of the diverting means 640 are closed by the discoid surface of thefirst portion 522 of thepipe 520. Preferably, the diameter of the gasket basically coincides at least with the diameter of the hole of thesewage waste pipe 30 and more preferably, is greater than the diameter of the hole of therecovery waste pipe 35. In other words, as shown inFIGS. 61A and 61B , the seal gasket O4 is firmly positioned at 90° between the twoholes hole 642 of the diverting means 640 for draining in thesewage waste pipe 30 or thehole 642 for draining in therecovery waste pipe 35, this because, as explained, the gasket is located at 90° between saidholes 642 diametrically opposed. - Note that said
first portion 522 of thewaste pipe 520, as for thesystem 118, comprises afirst surface 526 provided with aninclined portion 526A inclined from thehole 524 of the recovery waste pipe towards thehole 525 of the sewage waste pipe. - Furthermore, from the
first surface 526 peripherally raises anannular band 527 the same as theannular band 595 of thesystem 118, while in axial position there is aseat 528 for the firm engagement with a connectingelement 430 between thebushing 73 and thefirst portion 522 of thewaste pipe 520. Saidseat 528 and the corresponding connectingelement 430 are the same as those previously described with reference to thesystem 118. Therefore, the same seat has a base 529 having such peripheral sections so as to receive the inner section of the aforementionedconcentric protrusions 645 of the water diverting means 640, in completely the same way as for thesystem 118. - The
draining system 119 also comprises a control element 690 (FIG. 57 ) identical to the control element of thesystem 118. - Also the assembly and the operation of the
system 119 is the same as those previously described with reference to thesystem 118, therefore they will not be described any further. InFIG. 60 there is shown the interlock between thefirst portion 522 and the connectingelement 430 with the insertion of thewater diverting means 640. - In
FIG. 62 , thedraining system 120 is an embodiment variant wherein the elements in common with the previous embodiments have the same reference number. The present system differs from the previous ones because it enable to simplify to the maximum the variations with respect to traditional draining systems. In fact, theplug 800 with therespective control 611 and pin 610 are completely conventional just as thedrain 250, thestrainer 70 and thebushing 73 for fixing the strainer to the drain. Thepin 610 comprises only one shapedend 613 as for the previous embodiments. Therefore, the only pieces which are substantially modified are the waste pipe 440 and the divertingmeans 280. - Actually, the diverting means 280 are similar to the diverting means 640 described with reference to the
system 119. In particular, they have a general cylindrical shape with a bottom 281 and alateral wall 282. The bottom comprises a first 283 and a second 284 protrusion facing inward, hollow and coaxial, wherein the first protrusion overlaps the second (FIGS. 63, 64 ). Thefirst protrusion 283 has a cavity so as to precisely accommodate the section of theend 613 of thecontrol 610, preferably polygonal, to allow the rotation control of the same means. Furthermore, preferably, thefirst protrusion 283 is perforated so as to allow the draining of the water that would possibly leak therein. Thesecond protrusion 284 has instead a seat open outward so as to accommodate the above said rotation pin through a bayonet coupling as the one previously described. - Furthermore, the diverting means 640 comprise a first through
hole 285 and a second throughhole 286 formed on the bottom, in the proximity of the lateral wall and spaced by 90°. These holes, as in the foregoing, are so as to be alternatively overlapped to corresponding holes of the recovery waste pipe and of the sewage waste pipe. - Also the bottom 281 comprises a ramp 287 (
FIG. 63 ) as the one previously described and from the bottom circumference raises anannular band 288 provided with an outer threading (FIG. 62 ). - The
waste pipe 450 comprises afirst portion 451 and asecond portion 452. Thefirst portion 451 is similar to the first portion for example of thesystems pin 453 raises axially having a circumferential portion such that it engages with the seat of thesecond protrusion 284 of the diverting means 280 so as to realize the above said bayonet coupling and to allow the rotation of said means controlled by calibrated stop points, as already explained, so as to make theholes - The
second portion 452 of thewaste pipe 450 has a lid-like shape with a bottom 454 and alateral wall 455, wherein the lateral wall ends with aflange 456 threaded internally for the engagement with theannular band 288 of the first portion 451 (FIGS. 63, 64 ). The bottom 454 has acentral hole 457 surrounded by aring nut 458 internally threaded for the engagement with the threaded end of acommercial drain 250. In the proximity of the bottom circumference, anotherhole 459 is in communication withsleeve 459A for the connection with a pipe (not shown) for draining the water which might flow from the recovery waste pipe, as previously explained. - The assembly of the just described
system 120 is very simple since it requires the interlock between thepin 610 together with therelative control 611 and theplug 800 with the insertion of a gasket in a completely conventional way. Thebushing 73 is fixed through screwing inside thedrain 250 with the insertion of thestrainer 70 and the relative seal gasket on the bottom of the sink A. At this point, thepin 610 as previously arranged can be reversibly inserted in thedrain 250 so that itsend portion 613 exceeds the same drain. The diverting means 280 are fitted on thefirst portion 451 of thewaste pipe 450 with the insertion of conventional gaskets in the suitable seats according to what already explained also with reference to the previous systems. Subsequently, thesecond portion 452 is screwed on thefirst portion 451 and thedrain 250 with thepin 610 and theplug 800 is screwed on thering nut 458 of thesecond portion 452. - The operation of the
system 120 substantially occurs as previously described. Note that theend 613 of thepin 610 for activating the rotation of the diverting means 280 exceeds thedrain 250 to insert itself, through a shape coupling in the cavity of thefirst protrusion 283 of the same means. In turn the means engage on the same axis of the above said activating pin but on the opposite side on thepin 453 of thefirst portion 451 of thewaste pipe 450 in a rotatable way. In other words, the diverting means have two axial engagements facing the opposite directions such that in a simple but efficient way from one side they receive the rotation impulse transmitted by thecontrol element 611 and on the other side they are free to rotate about the pin of the waste pipe to select either the sewage waste pipe or the recovery waste pipe (FIGS. 63, 64 ). - In
FIGS. 65-67 , there is shown asystem 121 similar to the one just described. In particular the present system differs from the previous one in that the diverting means 290 comprise only one hollow andaxial protrusion 291 provided with a through hole (not shown inFIG. 66, 67 ). Furthermore, the cavity of such protrusions, as for the previous embodiment, is such that it can accommodate in a rotatable way a pin for the rotation of the waste pipe. Furthermore, in the foregoing, thebottom 292 of the means comprises ahole 293 for the recovery waste pipe and ahole 294 for the sewage waste pipe as well as aramp 295 to prevent water stagnation. - The
waste pipe 130 still comprises afirst portion 131 and asecond portion 132. Thefirst portion 131 is the same as thefirst portion 451 previously described with reference to thesystem 120. Also the second portion is basically the same as the second portion of thesystem 120 and differs from the latter for the presence of acoaxial seat 133 with a hollow pin 134 for the rotation of the aforementioned divertingmeans 290. The hollow pin corresponds to the rotation pin described with reference for example to thesystem 120 and differs for the presence of an axial hole (not shown in theFIGS. 66, 67 ) aligned with the hole of theprotrusion 291 of the divertingmeans 290. Conversely, theseat 133 opens on the opposite side with respect to the pin 134 and that is on the side facing therecovery waste pipe 35 and thesewage pipe 30. This seat, too, has a hole (not shown inFIGS. 66 and 67 ) in axis with the hole of the rotation pin. In fact, said seat has the function of accommodating anelastic element 509 such as a spring connected to a shaft P which passes through the holes respectively of theseat 133 and of thepin 291 of thesecond portion 132 of thewaste pipe 130 as well as of theprotrusion 291 of the rotation means 290. In particular, the shaft P comprises a first end P1 connected to said elastic element and a second end P2 hollow and protruding from saidprotrusion 291 towards the cavity of the divertingmeans 290. It is to note that the second end P2 has a cross section which locks precisely together with the cross section of theprotrusion 291. - The
control 610 of the diverting means 290 are the same as those described with reference to thesystem 120 and, therefore, have anend 613 which inserts itself with a shape coupling in the second end P2 of the shaft P, which, in turn, as previously said, inserts itself precisely in theprotrusion 291 of the diverting means 290 so as to allow them to rotate. - From the foregoing, it is clear that both the assembly and the operation are substantially the same as for the
previous system 120 with the difference that the rotation of thecontrol 611 in order to select the recovery system activates theelastic element 509 which after a predefined period of time automatically will return thesystem 121 to the position of the sewage system. - The advantage of the two described
last systems - From the foregoing, it is apparent that prior art drawbacks outlined in the introduction of the present description have been overcome and at the same time important advantages have been achieved.
- In fact, by means of a simple handy control located above the sink bottom it is possible to select a plurality of water waste pipes of the sink according to preferences or requirements.
- Furthermore, all embodiments of the present invention make it possible to realize draining systems in a simple and functional way, thus ensuring low production costs, low maintenance and low risks of malfunctioning.
- The draining systems herein described can undergo modifications and adaptations within the skilled in the art expertise, without anyway exiting from the protection field of the appended claims.
- For example, the forms described and shown of each element constituting the draining systems can be modified according to specific requirements or preferences. Similarly, sizes and coupling, insertion, connection means can have a great number of solutions comprising, for example, threaded or counter threaded screwing means, quick snap or bayonet coupling. Moreover, among the elements there can be used watertight elements such as conventional gaskets for example of the O ring type or flat gaskets, such as O ring O6 gaskets (for example
FIG. 47 ) at the base of the seat or rotation pin of the rotating disc so as to realize a seal in this point and reduce friction between the same components. - The control pins to activate the flow diverting means can have various forms and controls suitable for specific requirements. In particular, the pins and the corresponding diverting means described for each embodiment can be combined one with the other also in ways different from the one described and shown in the figures, but yet having in mind their function, their dimensions and possible modifications or adjustments entirely concerning the shape of the means associated to them.
- Overflow systems can also be provided in those embodiments wherein they have not been shown or described.
- Also materials can be of different kinds according to specific requirements or preferences. In fact, it is well known that the most used materials in the sector are plastic or metal, among plastic materials the most known are the PP, ABS and among metals stainless steel, brass and other chromed metals.
- Seeger type rings can be provided in all the embodiments wherein the diverting means are constituted by a disc or rotating cylinder on a pin of the waste pipe.
