DETAILED DESCRIPTION OF THE INVENTION:

The present invention discloses automatic self-cleaning public toilets for the public’s convenience in group usage. The JANI eco self-cleaning public toilet of the present invention has the following major components:
Major components of self-cleaning public toilet are:
* Vacuum flush system
* 4 stage sequential auto wash system
* 6 stage sequential floor auto wash system
* Nozzle tube placement on the commodes, Urinal bowls, Wash Basin and floor
* Pause and play function.
* Sensor operated wash basin and urinals.
* Robo Drive for Floor Wash
Vacuum Systems:
1. Vacuum flush
2. Dumping cycle
Vacuum flush: Consists of a primary vacuum pump connected in series with two tanks, these tanks are connected in parallel with each water closet through PVC pipes with vacuum valves for sealing the vacuum.
The vacuum system comprises of vacuum valves tanks and vacuum pump
The tanks and the vacuum pump are connected in series with vacuum grade hose pipes, The water closets and the tanks are connected with PVC pipes with vacuum valves to hold the vacuum. When the vacuum valve opens the vacuum breaks and the black water from the W/C gets dumped in to the collection tank.
Dumping cycle: The collection tank is programmed to dump the waste collected from the water closets automatically. During the dumping cycle the dumping valve connected in between the collection tank and drainage line opens to dump out the waste, since the valve is placed at the bottom and the collection tank is under vacuum the waste will not flow towards the drainage. Thus a valve on the vacuum tank opens simultaneously as the dumping valve opens and breaks the vacuum for the waste in the collection tank to flow to the drainage. Every time the dumping cycle starts the collection tank gets a spray of clean water to wash off the all the waste sticking on to the sides of the tank’s walls. Once the set time is reached the dumping valve, vacuum valve and the water valve on the collection tank all closes and initiates the vacuum pump to create vacuum in to the system. Once the vacuum is generated the water closets are ready for vacuum flushing.
Note: The whole dumping process takes about a minute to complete. The dumping process occurs automatically once the than is filled.
This system is completely responsible for the operation of water closets and dumping the waste from the collection tank.

4 stage sequential auto wash system
This unique feature is designed to extract maximum cleaning with minimum soap and water consumption. During this operation the water closet, urinals & the wash basin gets a dose of detergent followed with two rinses and an air wash. The four stages are names are as flows
1. DOSING CYCLE
2. RINSE 1
3. RINSE 2
4. AIR WASH
Dosing cycle: when the wash cycle is initiated the dosing pump starts injecting detergent in to the main header line then a sequence on valves open and close for a set period of time which allows water air and detergent mixture to be sprayed on throughout the surface area of the Commode, Urinal Bowl and Wash Basin through the strategically placed nozzles embedded in them.
All the commodes, urinal bowl and wash basin are clubbed in pairs and when the dosing cycle is on progress each pair gets a dosed on clock wise sequence. Once the dosing cycle is completed the system pauses for a set period of time for the soap to react with the dirt on the surface of the commodes, urinal bowl and wash basin. Once the delay time is reached the system initiates the rinse 1 function.
Rinse 1: When the rinse 1 starts it follows the same sequence if the dosing cycle except for this time only water valves will operate (both air and dosing pump remains shut). Rinse 1 washes off all the soap along with the dirt and debris
After the rinse 1 cycle then rinse 2 cycle starts instantly
Rinse 2: When the rinse 2 starts it follows the same sequence as rinse1 except for this time water valves and air valves will operate (dosing pump remains shut). Rinse 2 is a high power water and mixture jet wash. This process jets off all the remaining soap along with the dirt and debris.
Air wash: Once the rinse 2 is completed the air wash kicks in, it is a stream of compressed air focused towards the ceramics to push of excess moisture of the surface rendering the W/c, Urinals bowl and wash basin almost moisture free.

6 stage sequential floor auto wash system
This feature is designed just like the W/C, Urinal Bowl and Wash Basin wash to extract maximum cleaning with minimum soap and water consumption but focused towards the floor. During this operation the floor of the toilet room gets a dose of detergent followed with two rinses, Robo Cleaning and an air wash.
1. DOSING CYCLE
2. RINSE 1
3. ROBO DRIVE CLEANING
4. RINSE 2
5. ROBO DRIVE CLEANING
6. AIR WASH
Dosing cycle: When the ceramic wash concludes the dosing pump starts again to inject detergent in to the main header line then a sequence of valves open and close for a set period of time according to a pre defined sequence which allows water, air and detergent mixture to be sprayed on throughout the surface area of the floor through the strategically placed nozzles embedded in the PU tubes and connectors.
The floor area is divided in to eight segments and each segment will operate in a sequential manner. When the dosing cycle is on progress each segment gets a dosed of soap, water and air mixture following the pre programmed sequence. Once the dosing cycle is completed the system pauses for a set period of time for the soap to react with the dirt on the floor. Once the delay time is reached the system initiates the rinse 1 function.
Rinse 1: When the rinse 1 starts it follows the same sequence of the dosing cycle except for this time only water valves will operate (both air and dosing pump remains shut). Rinse 1 washes off all the soap along with the dirt and debris.
Robo Drive: Once the rinse 1 is complete the Robo Drive will start moving from one end to other end by brushing the floor and mopping and pushing the waste water into the drains provided in the both ends of the toilet complex
Then after the Robo drive finishes its working and go back to the parking station then the system instantly starts rinse 2 sequence.
Rinse 2: When the rinse 2 starts it follows the same sequence as rinse1 except for this time water valves and air valves will operate (dosing pump remains shut). Rinse 2 is a high power water and air mixture jet wash. This process jets off all the remaining soap along with the dirt and debris.
Robo Drive: Once the rinse 2 is complete the Robo Drive will start moving from one end to other end by brushing the floor and mopping. Then after the Robo drive finishes its working and go back to the parking station
Air wash: Once the rinse 2 is completed the air wash kicks in, it is a stream of compressed air focused towards the floor to push of excess moisture on the surface rendering the floor almost moisture free.

Unique pressurized mixing chamber technology
The present disclosure proposes an unique technology to increase water pressure and decrease water consumption by mixing pressurized water and compressed air. The mixing ration of water and air are at a specific pressure. This enables us to get a constant jet flow of pressurized water to clean the surface efficiently and drastically minimize the consumption of water.
The air is fed in the primary water line at an angle via a mixing chamber for efficient mixing and consistent flow. Through mixing chamber we can seamlessly perform any programmed wash cycle without the any leak and back feed.

Nozzle network for intense cleaning at critical points
All the newly designed and developed FRP water closet, wash basin and urinals are embedded with strategically placed nozzles facing the internal and external side except for wash basin it only has internal facing nozzles. These nozzles are strategically placed to extract maximum cleaning hidden beneath the custom fabricated FRP wash basin and urinals, in wash basin the nozzle tubes are concealed beneath the buffer space between the granite opening and wash basin. For the floor the whole are of the floor is divided in to segments and the nozzle tubes are places on the corner walls of the floor.
These nozzles can operate in both mediums (Air and water) at a very high pressure. All the nozzles spread the water and air at a specific degree for maximum surface area coverage. These nozzles tubes are directly connected from the mixing chamber.
Special angled spoon nozzles are embedded at the front of each w/c for the optimum surface coverage.

Pause and Play function
The invention has incorporated a special logic for power cut or change over condition to save time, power and water via a pause and play function while the wash cycle function is being executed. During this condition and if the wash cycle function is running the inbuilt system will detect the power cut and pause the wash cycle from executing further till the power returns back and once the power is back the wash cycle will start from where it left and execute the function as programmed.
The logic circuit consists of raw power source powering the PLC unit via a 1kVA inverter. when the raw power fails the UPS takes over on powering the PLC. Furthermore, the PLC gets an input from a RAW power super supervision relay that there is no raw supply, the PLC has a logic programmed to pause the function till the RAW supply fail initiation is reset. Once the raw supply takes over the supervision relay resets and the paused wash cycle function starts playing from where it left.
Thus, the present invention saves the time precious resource and money. Further this type of construction can be easily disassembled and reinstalled at other location with minimum wastage.

Sensor operated wash basin and urinals
Considering the pandemic crisis inventors have developed a robust and yet reliable wash basin layout. All the wash basin spouts are sensor operated which means you may never have to touch anything to apply soap, hand wash and dry your hands. It consists of a pair of soap, water and air spouts. A dash of soap on demand, stream line adequate water flow of 400ml for water saving. we have also managed to developed a hand drier system which does not spray the washroom air on to your hand in the name of drying.
The urinals are also unique on the sensor operation due to the fact that it only uses 400ml of water per flush commanded by PLC. This amount of water is adequate as the urinals gets washed thoroughly for every wash cycle which also helps in eliminating odour.
The whole system is controlled by PLC thus enabling us to adjust the timing of valve operation based on requirement without dismantling the sensors for adjustment.
Accordingly, the present invention addresses the following issues:
• Water Savings - Typical savings of 75-80% on water and soap Vs. conventional public toilets.
• Speed of Construction - Reduced labour costs; just lift and place the toilet room on any given location on a flat plane, connect drainage, water and power connection, the JANI eco will be up and running.
• Environmentally Responsible – Recycle ability and reduce reliance on wood-based products.
• The whole toilet room is skid mounted prefabricated and can be transported to any location on road, thus a modular and mobile washroom which can be easily relocated.
• Odour free public toilets as the toilet room can be washed with a push of a button. Whenever the care taker feels the toilet room needs a wash.
• Lowering man power to clean the toilet room as the whole toilet room automatically washes its self and since it is automated the wash results are consistent always.
• Extremely hygienic way of water closet flushing through vacuum operation.
