1)etailcd I)escription of a preferred embodiment of the invention.
In Figure 1 there is a twin assembly of Washing Machines assigned with reference numerals (100 and 200). The inachines (100, 200) -are connected through a channel means liaving a two- way solenoid valve means (300), for channel=ling water from one to another. The input to the channel (300) passes through a Sieve and/or Filtration device (310), to remove suspended implirities like Lint and other large particles.
Additionally, the channel means passes through an' Ultraviolet or Gamma rays=
irradiation chamber (320) to remove pathogens. The channel is provided with a back-flusli device taking input water from a tap and discharging back-flushed .water into a drainage.
Both the washing machines ( 100, 200) have independent tap water inlets (110, 210 ) and effluent drainage pipes (130, 230).
13oth the machines (100, 200) are controlled by a single controller (400) with a pre-programmed logic and a default setting that can be changed through electronic push buttons(410) and knobs (420), and is displayed through electronic panels (430, 440) associated with the washing machines (100, 200).
'1'hc (irst washing machine (100) may be used foi- lesser soilcd, e.g. r-'=arnicnts and thc second washing machine (200) can be used for heavily soiled e.g. lincn, towcls, mops.
shoes, doormats etc.
'fhe controller (400) is programmed to operate the two-way solenoid valve means (300), to direct effluent of each selected cycle of the first-machine (100) as input for the second tnaciiine (200). Additionally, effluent of each cycle of the washing machines (100, 200) is dischargeable as' waste water through the solenoid valve means (300) directing the flow to the drainage pipes (130 , 230).
The controller (400) is programmed with an interlocking logic, as explained below through a typical exemplary scenario.
The pre-wash option of the first machine (100) tnay include extracting fresh water from the first water inlet (110), drawing stored chemicals from disposal tray (140), soaking and tumbling the garments in the solution, and channelling the pre-washed water to the second machine (200) on spinning. The second machine (200) is programmed to complete its pre-wash cycle, spin and release the re-used pre-washed water through the drainage (230), while the first machine (100) is completing its Wash cycle after drawing fresh water through the first water inlet (110). If a hot wash option has been selected for'*the first machine (100) e.g. by selecting 'cotton' at knob (410), the controller (400) causes an inbuilt electrical heater equipped with a thermostat in the washing machines (100, 200) to control the water temperature at a desired level. When the first washing machine ( 100) completes its Washing cycle, it spins and channels hot/cold wash water (with remaining detergent) to the second washing machine( 200) through the channel (300). The first machine (100) now starts a Rinse cycle while the second machine (200) starts its Wash cycle. Again if a hot wash option has been selected for the second machine (200), the temperature of recycled wash water is maintained at a desired level through the inbuilt heating device as explained hereinabove. The second machine (200) on completing its Wash cycle, spins while discharging the reused washed water through the drainage (230), and stands by for input Rinsed water from the first macliine (100). Likewise, at any stage the first machine (100) may also stand by till the second machine (200) is through with a cycle and.becomes ready to take intended grey water. Then the first machine(100) spins and phannels Rinsed water into the second machine 200. The second machine(200) then performs the rinse operation by using the recycled water.
Likewise, the first and the second machines (100, 200) repeat the process if a second rinse lias been opted. Finally, the first machine (100) on completing all the selected cycles, allows its door to open and is ready for the next load. The second machine(200) may, in the last cycle, draw a specified quantity of fresh tap water for a final Rinse with or without specified disinfectants stored in a disposal tray(240.). The second machine (200) then completes the cycles by final spinning of its load, at a specified RPM. A typical program cycle is shown in Figures 4A and 4B.
Additionally, the second machine (200) may be operated to perfoi-m as many fi-esh water cycles as desired. For example, there may be a'double wash' option at electronic panel (440), if selected will operate the second machine (200) to start a fresh water wash cycle before the final fresh \vater rinse in the above example. In this seenario, any of the fresh water cycle discharge ni~iy i/c stored and recycled as desirable.
The Rinse cycles may consist several shot-t bursts of rinsW, i which little water is used, which may be expelled through the drainage pipcs (130. 230), while the rinsed water of full rinse cycles only be channelled into the nexl tnachine.
A reservoir chamber may be also provided betwe.en the I wlj machines ( 100, 200)for teniporary storagc of water of each cycle, operated thrcr+jt;h a second set of solen.oid valve means connecting it with the inachines (100, 200) oii both the sides, as shown in Figures 2A and 2B. In that case, the channel (300) rriay be placed between the intermediate reservoir and the second machine (200). lri another configuration, the ftlter/sieve (310) is disposed between the first machinc (100) and the intermediate reservoir while the irradiation device (320) may be desigried between the intermediate reservoir and the second machine (200). Both the rnachines (100, 200), the intermediate reservoir including the channel are configurable in a vertically stacked system as shown in Figure 2B.
The filter/sieve (310) may be provided with a known bacl~-flush means. In case of the intermediate reservoir being provided, the program logit; is accordingly set, e.g. the first machine(100) will hold from releasing grey water ,Wlected for recycling if the intermediate storage is not ready to take it. Additionally, the system inay be operable to store grey water of any particular cycle of any of the rttachines, for later use in the starting cycle of any of the machines as desired. l f a machine is being used singly; the grey water so stored for later use may be of any cyclc atid in that case, if a single machine is used again, the stored "water is also recycled t-'-i a-iy cycle as selected in the controller. For example, if the machines(100, 200) are V,,lccted to operate singly, the wash water of wash cycle of the first machine(] 00) may be selected for use as recycled wash water for the next load of the second, rr+aohine ( 200), or of the first machine (100) again, by causing the two-way solenoid qalves to operate as shown in Figure 2A.
The channel (300) may also be provided with an eleotronic sensor (330) to check turbidity of the channelled pre-washed and/or rinsed wat1=r of the first machine (100j, and beyond a specified threshold, causes the controller (4,00) to show a warning signal and/or halt operations. Alternatively, the controller (400) is programinable to operate a solenoid valve (340), to release the extra turbid water g;:cfnuent, as shown in higure 3B.. In this scenario, the controller (400) may bc furthcsroperable to cause the second macliine (200) to extract fresh tap water at (210) for the next cycle. In any of' the cycles, the second machine (200) may also be operablt; ',-) draw additional detergents stored in the disposal tray (240).
Additional disinfection means may be provided such an; 6anima i-ay iri-adiation at the first niachine (100) before the start of first cycle and/or the second machine (200) aftcr the last cycle.
Separate motors are provided to run both the niac~i tiflc ( 100, 200) in tandem, controlled througii the comnion controller (400), invrporated with interdependent logics such as explained herein above by way of examl'jft's=
Likcwise, there may be other options, with an essential interlock of wash cycles in the first and the second machine (100) and (200) in such a way that wllenever the second machine (200) is not ready to take intended input of grey water from the first machine (100), the next cycle of the first machine (1-00) will remain on hold, and vice-versa i.e.
the second machine (200) will hold the next cycle till the first machine (100) has performed a corresponding task selected. There may also be an option of switching ofl' the interlock program. a'hen both the machines (100, 200) become independent machines operablc separately like conventional washing machines.
In that case the controller (400) may operate both the machines(100, 200) independently, or two separate conventional controllers of the machines (100, 200)may operate each machine individually.
Figure 4A shows a typical example situation of text displayed at the panels (430, 440) The 1Cnob (410) preferably h,as wash type options for (100), e.g. Cotton, Synthetic etc. Likewise, the knob (420) has options for the second machine(200), like Soiled (for heavily soiled items like mops, doormats, shoes etc.), Linen etc.
Display panels (430,440) shows typical default setting and maneuverability of individual cycles in each machine. In the example display panel, 5 cycles in each machine are selectable as yes/no (y/n) options. Against each of these 5 cycles at the display panel (430), there is an additional option selections viz. 'Recycle or Not' at the display panel (430). Similarly, against each of the 5 options at the display panel (440). Recycled or Fresh water usage is displayed, depending on selections in the first machine (100). Upon selecting a particular cycle option in one machine, certain options are automatically selected in the other. For example any selected cycle at the display panel (430) also selected as - Recycle will automatically lead to the corresponding cycle of the other display panel (440) selected as 'y' and 'Recycled'.
Likewise, if any cycle at =the display panel (440) is selected as "Freshwater"
thc corresponding previous cycle in the other display panel (430) displays as 'n' against 'Recycle,' and operate the first maciiine (100) accordingly. As such, various permutations and combinations are applicable by selecting options at the knobs (410) ( 420) and at the display panels (430 , 440). A typical chronological sequence of tandem operation of the two machine cycles corresponding to the default selections of Figure 4A is -shown in Figure 4B.
To simplify the panel options at the display panels ( 430, 440), pre-set combinations may be selectable through text displays like "Max Cleaning + Low Water Saving"
for example in case of the default setting shown here. Fiowever, if all cycles are se(ectcd for Recycle in the example situation, the text display may be "Max Cleaning -+-Highest Water Saving". Likewise, if only Wash and one Rinse cycle is selected and both are also selected for Recycle, the text can be "Min Cleanino + Max Water Savings. If however, additionaliy Pre-Wash is also selected, it could be "Medium cieaning + Max Vater Saving" and if yet another Fresh Rinse is selected at thc display panel (440), it could be "Medium Cleaning + Low water Saving" etc. In each of these selections, further program logic, also known as Fuzzy logic in automated washing machines, may be applied, such as sliortening the length of wash cyc:le automatically if the selection is "Min Cleaning + Max Power Saving" etc.
"I'hc tandem type configurations of the washing system may be prcierably horizontal as shown here, or a vertically stacked twin i.e. the first rnachine (100) on top of' the sccond macliine (200), to save space or any other desirable reason.
'I'ypical Wash Cycles for both the machines (100, 200) operating in tandem,' controlled through the common controller (408) is shown below for example:
Various advantageous features of the washing machine are the following:
I. Any cycle of the first machine (100) dischargeable as effluent and rest recyclable as input for the second machine (200).
2. Fresh water at any cycle option for the second machine (200) as well, e.g.
last rinse as exemplified above.
3. Any selected cycle of the first machine(100), also being selectable as 'recycle' in the second machine (200).
4. Independent temperature controls of the machines (100 , 200) 5. Different Wash logic selectable in the first and second machine(100, 200);
e.g.
'delicate' in the first machine 100 and 'hard' in the second machine (200).

1)etailcd I)escription of a preferred embodiment of the invention.
In Figure 1 there is a twin assembly of Washing Machines assigned with reference numerals (100 and 200). The inachines (100, 200) -are connected through a channel means liaving a two- way solenoid valve means (300), for channel=ling water from one to another. The input to the channel (300) passes through a Sieve and/or Filtration device (310), to remove suspended implirities like Lint and other large particles.
Additionally, the channel means passes through an' Ultraviolet or Gamma rays=
irradiation chamber (320) to remove pathogens. The channel is provided with a back-flusli device taking input water from a tap and discharging back-flushed .water into a drainage.
Both the washing machines ( 100, 200) have independent tap water inlets (110, 210 ) and effluent drainage pipes (130, 230).
13oth the machines (100, 200) are controlled by a single controller (400) with a pre-programmed logic and a default setting that can be changed through electronic push buttons(410) and knobs (420), and is displayed through electronic panels (430, 440) associated with the washing machines (100, 200).
'1'hc (irst washing machine (100) may be used foi- lesser soilcd, e.g. r-'=arnicnts and thc second washing machine (200) can be used for heavily soiled e.g. lincn, towcls, mops.
shoes, doormats etc.
'fhe controller (400) is programmed to operate the two-way solenoid valve means (300), to direct effluent of each selected cycle of the first-machine (100) as input for the second tnaciiine (200). Additionally, effluent of each cycle of the washing machines (100, 200) is dischargeable as' waste water through the solenoid valve means (300) directing the flow to the drainage pipes (130 , 230).
The controller (400) is programmed with an interlocking logic, as explained below through a typical exemplary scenario.
The pre-wash option of the first machine (100) tnay include extracting fresh water from the first water inlet (110), drawing stored chemicals from disposal tray (140), soaking and tumbling the garments in the solution, and channelling the pre-washed water to the second machine (200) on spinning. The second machine (200) is programmed to complete its pre-wash cycle, spin and release the re-used pre-washed water through the drainage (230), while the first machine (100) is completing its Wash cycle after drawing fresh water through the first water inlet (110). If a hot wash option has been selected for'*the first machine (100) e.g. by selecting 'cotton' at knob (410), the controller (400) causes an inbuilt electrical heater equipped with a thermostat in the washing machines (100, 200) to control the water temperature at a desired level. When the first washing machine ( 100) completes its Washing cycle, it spins and channels hot/cold wash water (with remaining detergent) to the second washing machine( 200) through the channel (300). The first machine (100) now starts a Rinse cycle while the second machine (200) starts its Wash cycle. Again if a hot wash option has been selected for the second machine (200), the temperature of recycled wash water is maintained at a desired level through the inbuilt heating device as explained hereinabove. The second machine (200) on completing its Wash cycle, spins while discharging the reused washed water through the drainage (230), and stands by for input Rinsed water from the first macliine (100). Likewise, at any stage the first machine (100) may also stand by till the second machine (200) is through with a cycle and.becomes ready to take intended grey water. Then the first machine(100) spins and phannels Rinsed water into the second machine 200. The second machine(200) then performs the rinse operation by using the recycled water.
Likewise, the first and the second machines (100, 200) repeat the process if a second rinse lias been opted. Finally, the first machine (100) on completing all the selected cycles, allows its door to open and is ready for the next load. The second machine(200) may, in the last cycle, draw a specified quantity of fresh tap water for a final Rinse with or without specified disinfectants stored in a disposal tray(240.). The second machine (200) then completes the cycles by final spinning of its load, at a specified RPM. A typical program cycle is shown in Figures 4A and 4B.
Additionally, the second machine (200) may be operated to perfoi-m as many fi-esh water cycles as desired. For example, there may be a'double wash' option at electronic panel (440), if selected will operate the second machine (200) to start a fresh water wash cycle before the final fresh \vater rinse in the above example. In this seenario, any of the fresh water cycle discharge ni~iy i/c stored and recycled as desirable.
The Rinse cycles may consist several shot-t bursts of rinsW, i which little water is used, which may be expelled through the drainage pipcs (130. 230), while the rinsed water of full rinse cycles only be channelled into the nexl tnachine.
A reservoir chamber may be also provided betwe.en the I wlj machines ( 100, 200)for teniporary storagc of water of each cycle, operated thrcr+jt;h a second set of solen.oid valve means connecting it with the inachines (100, 200) oii both the sides, as shown in Figures 2A and 2B. In that case, the channel (300) rriay be placed between the intermediate reservoir and the second machine (200). lri another configuration, the ftlter/sieve (310) is disposed between the first machinc (100) and the intermediate reservoir while the irradiation device (320) may be desigried between the intermediate reservoir and the second machine (200). Both the rnachines (100, 200), the intermediate reservoir including the channel are configurable in a vertically stacked system as shown in Figure 2B.
The filter/sieve (310) may be provided with a known bacl~-flush means. In case of the intermediate reservoir being provided, the program logit; is accordingly set, e.g. the first machine(100) will hold from releasing grey water ,Wlected for recycling if the intermediate storage is not ready to take it. Additionally, the system inay be operable to store grey water of any particular cycle of any of the rttachines, for later use in the starting cycle of any of the machines as desired. l f a machine is being used singly; the grey water so stored for later use may be of any cyclc atid in that case, if a single machine is used again, the stored "water is also recycled t-'-i a-iy cycle as selected in the controller. For example, if the machines(100, 200) are V,,lccted to operate singly, the wash water of wash cycle of the first machine(] 00) may be selected for use as recycled wash water for the next load of the second, rr+aohine ( 200), or of the first machine (100) again, by causing the two-way solenoid qalves to operate as shown in Figure 2A.
The channel (300) may also be provided with an eleotronic sensor (330) to check turbidity of the channelled pre-washed and/or rinsed wat1=r of the first machine (100j, and beyond a specified threshold, causes the controller (4,00) to show a warning signal and/or halt operations. Alternatively, the controller (400) is programinable to operate a solenoid valve (340), to release the extra turbid water g;:cfnuent, as shown in higure 3B.. In this scenario, the controller (400) may bc furthcsroperable to cause the second macliine (200) to extract fresh tap water at (210) for the next cycle. In any of' the cycles, the second machine (200) may also be operablt; ',-) draw additional detergents stored in the disposal tray (240).
Additional disinfection means may be provided such an; 6anima i-ay iri-adiation at the first niachine (100) before the start of first cycle and/or the second machine (200) aftcr the last cycle.
Separate motors are provided to run both the niac~i tiflc ( 100, 200) in tandem, controlled througii the comnion controller (400), invrporated with interdependent logics such as explained herein above by way of examl'jft's=
Likcwise, there may be other options, with an essential interlock of wash cycles in the first and the second machine (100) and (200) in such a way that wllenever the second machine (200) is not ready to take intended input of grey water from the first machine (100), the next cycle of the first machine (1-00) will remain on hold, and vice-versa i.e.
the second machine (200) will hold the next cycle till the first machine (100) has performed a corresponding task selected. There may also be an option of switching ofl' the interlock program. a'hen both the machines (100, 200) become independent machines operablc separately like conventional washing machines.
In that case the controller (400) may operate both the machines(100, 200) independently, or two separate conventional controllers of the machines (100, 200)may operate each machine individually.
Figure 4A shows a typical example situation of text displayed at the panels (430, 440) The 1Cnob (410) preferably h,as wash type options for (100), e.g. Cotton, Synthetic etc. Likewise, the knob (420) has options for the second machine(200), like Soiled (for heavily soiled items like mops, doormats, shoes etc.), Linen etc.
Display panels (430,440) shows typical default setting and maneuverability of individual cycles in each machine. In the example display panel, 5 cycles in each machine are selectable as yes/no (y/n) options. Against each of these 5 cycles at the display panel (430), there is an additional option selections viz. 'Recycle or Not' at the display panel (430). Similarly, against each of the 5 options at the display panel (440). Recycled or Fresh water usage is displayed, depending on selections in the first machine (100). Upon selecting a particular cycle option in one machine, certain options are automatically selected in the other. For example any selected cycle at the display panel (430) also selected as - Recycle will automatically lead to the corresponding cycle of the other display panel (440) selected as 'y' and 'Recycled'.
Likewise, if any cycle at =the display panel (440) is selected as "Freshwater"
thc corresponding previous cycle in the other display panel (430) displays as 'n' against 'Recycle,' and operate the first maciiine (100) accordingly. As such, various permutations and combinations are applicable by selecting options at the knobs (410) ( 420) and at the display panels (430 , 440). A typical chronological sequence of tandem operation of the two machine cycles corresponding to the default selections of Figure 4A is -shown in Figure 4B.
To simplify the panel options at the display panels ( 430, 440), pre-set combinations may be selectable through text displays like "Max Cleaning + Low Water Saving"
for example in case of the default setting shown here. Fiowever, if all cycles are se(ectcd for Recycle in the example situation, the text display may be "Max Cleaning -+-Highest Water Saving". Likewise, if only Wash and one Rinse cycle is selected and both are also selected for Recycle, the text can be "Min Cleanino + Max Water Savings. If however, additionaliy Pre-Wash is also selected, it could be "Medium cieaning + Max Vater Saving" and if yet another Fresh Rinse is selected at thc display panel (440), it could be "Medium Cleaning + Low water Saving" etc. In each of these selections, further program logic, also known as Fuzzy logic in automated washing machines, may be applied, such as sliortening the length of wash cyc:le automatically if the selection is "Min Cleaning + Max Power Saving" etc.
"I'hc tandem type configurations of the washing system may be prcierably horizontal as shown here, or a vertically stacked twin i.e. the first rnachine (100) on top of' the sccond macliine (200), to save space or any other desirable reason.
'I'ypical Wash Cycles for both the machines (100, 200) operating in tandem,' controlled through the common controller (408) is shown below for example:
Various advantageous features of the washing machine are the following:
I. Any cycle of the first machine (100) dischargeable as effluent and rest recyclable as input for the second machine (200).
2. Fresh water at any cycle option for the second machine (200) as well, e.g.
last rinse as exemplified above.
3. Any selected cycle of the first machine(100), also being selectable as 'recycle' in the second machine (200).
4. Independent temperature controls of the machines (100 , 200) 5. Different Wash logic selectable in the first and second machine(100, 200);
e.g.
'delicate' in the first machine 100 and 'hard' in the second machine (200).
6. Controlling cycles in the machines (100 , 200), depending on selection of washables types e.g. Cotton in the first machine (100) and heavily Soiled kitchen mops in the second machine (200).
7. Interlocked delay operations like starting the machines (100, 200) at a pai-ticular time, or stopping at a particular stage e.g. after pre-washing at the first machine (100). Additionally, keeping the first machine (100) on 'hold' till tlie second machine (200) is not ready to take the intended input of grey water from the first machine (100).
8. On finishing the cycl'es of a particular machine earlier, allowing the door to open for taking away the cleaned laundry and placing next load to be washed.
9. After removing the laundered inaterial , grey water is retui-ned from the machine still in use to the emptied one, for further use in any'of the machines as selected. The 2"d Rinse water may be redirected to the first machine (100) for tempor.ary storage and subsequent use for the first cycle of the next load in the second machine (200).
10. Likewise, wllen only the first machine (100) is used, using the second machine (200) for storing grey water of any cycle, e.g. either wash or rinse, for later use in any cycle of the first machine (100).
11. On switching off the interlock logic, both the machine (100, 200) are operable independently as two conventional machines.
12. Interrupted disposal of Detcrgcnt, Bleacli and othcr Solvent through disposal trays (140, 240) in both machines (100, 200); i.e. any of the cycle may be interrupted to operate the machine to extract spccified material stocked in the disposal tray ( 140, 240).
Thc multiple canbination may have one or more of any type of autoinatic wasliing machine such as front loading tumble or top loading agitator etc. For example the first machine may be front loading tumble wash suitable for delicate clothes and the second may be top loading agitator wash more suitable for heavily soiled linen etc.
The tandein type washing system may be placed on the roof-top for furtlier recycling of effluent waters of the first machine (100) and/or the second= machine (200) discharged through their associated drainage pipes( 130, 230) . In this configuration, the said drainage pipes (130, 230) are connected to a storage device such as a reservoir (500). The reservoir may pass the effluent water through a Channel means that may be similar to the channel means (3700), shown here at (505). The channel means (505) may lead to a storage tank (510) that may have filtration means such as divider plates with descending level of pores or no-porous plates placed in such a way that it allows overflow to the next chamber. Additionally, the storage tanks may have transparent panels that allow solar rays to pass through in the stored water, foi-prevention of and further breakdown of pathogens. A solar heatei- may also be cmployed if the water is desired to be heated.
The biggest advantage of this novel construction is that the ef(luent grey \vater discharged and stored at the roof top does not require any pumping. As the fresh water used for wasliing is generally already stored at the rooftops, there is net saving of energy. 1'he grey water may be further processed using 'sun-rays and may be supplied through a separate pipelines for flushing (520), gardening (530), car-wash (540) and the like. Moreover, laundering at roof top will also facilitate drying clothes under the sun, further saving efforts to carry the washed clothes there. An additional draina~~e pipe running through the bottom of all compartments (550) may be connected to a hydra.nt (560) for any use.including for ground water recharging through a pit (570), additional water source in etnergencies like fire as shown (580).
In a different scenario, rnore than two machines may be interconnected serially, e.g. a third machine operable to extract selected effluents of the second and/or first machine, and so on. This type of modular configuration may be more useful in an industrial situation where lieavily soiled load maybe more.
Many known devices and processed may be used to clean the final effluents of the tandem washing machines placed at the rooftops. Through additional mechanical means, alternative drainage and fool-proofing systems may be provided for contingencies like power-failure, system crash and/or overflow etc.
Althougli the present invention has been described in detail here, various changes, substitutions, and alterations may be readily ascertainable by those skilled in the art and may be made herein without departing from the spirit and scope of the present invention as defined in the following claims. Moreover, the present invention is not interided to be limited in any way by any statement in the specification that is not otherwise re(lected in the appended claims.
