TECHNICAL FIELD
[0001] The present invention relates tzenerally to the field of
toilets, and more
specifically to a system and a method for flush and waterless hygienic
toilets.
BACKGROUND
[0002] A toilet is a sanitation fixture used for storing and/or
disposai of human
waste. In developed countries, ceramic toilets scats are commonly used and are
mainly usually used in the western countries. White squat toilets are common
in East
Asia and/or developing countries.
sµ [0003] In many developing countries, especially in rural areas.
portable toilets
and dry toilets such as pit latrines and composting toilets are used. Dry
toilets are =
usually placcd in outhouses or in a remote location near a bouse. Further, the
portable
toilets are commonly used at construction sites, parks, outdoor recreational
events,
and wherever toilets are needed for a limited time period only or where
sanitary
sewers are unavailable.
[0004] Further, for a temporary settlement, the portable toilets are
installed on the
rear chassis and/or on the attachment chassis of trucks and/or Lorries. A
regular
'Cleanup and maintenance of these portable toilets are required that consumes
lot of
vvater and human resource. Further, the water is already available in scarcity
and thus
need to be avoided.
[0005] Further, the problem that exists with portable toilets is that
while making
entry into the toilet cabin, the human waste stored in the human waste
reservoir is
visible through the hole of the toilet which makes a very inconvenient moment
for the
1
CA 3007604 2019-12-04
user. Further, the open toilet hole spreads the smell of the human waste
inside the
toilet cabin that makes a very unhygienic environment for the person inside
the cabin.
Further, flues and mosquito tend to accumulate near the human waste reservoir
which
further can spread a disease.
[0006] Further, for providing a comfortable environment in portable toilet,
chemicals are used for disinfecting the waste storage tank and reducing
lingering
smell of the human waste. The problem with disinfecting chemicals is that they
are
very harmful for the environment and even difficult to dispose.
[0007] Several inventors have worked on the same problem and some works of
the inventors are discussed below:
[0008] The document US9493937B2 discloses a portable toilet that contains a
filter which separates the solid waste and liquid waste in separate containers
for solid
and liquid waste. The collected waste is collected in plastic bags and used
for useful
purposes such as manure and/or compost.
[0009] The document US 20160143492 Al provides a portable toilet system
having a foldable toilet that is configured to hold a disposable bag in it.
Further, the
system includes a collapsiblc enclosure that Can be positioned over the toilet
to
provide privacy for the user.
[0010] However, the problem of toilet spreading the smell through the open
center hole of toilet, poor ventilation system inside the toilet cabin needs
to be
improved. Further, improvements are required to provide better hygienic,
healthy and
comfortable conditions inside the toilet cabin.
[0011] In light of the discussion above, there is clearly a need in the art

is provided a slope inclining toward the outlet (910) of the reservoir (110)
that moves
the human waste towards the outlet (910) of the reservoir (110). Further, the
drain
pipe (940) is having a reverse U-shaped bend (930) in between the reservoir
(110) and
the underground tank (950), near the reservoir (110).
[0074] In accordance with embodiment of the invention, the reverse U-shaped
bend (930) is having a lever (920) capable of tilting the reverse U-shaped
bend (930)
to an angle of 90 degrees, when pulled. Figure 10 illustrates a top view
(1000) of the
system (900) for flush and waterless hygienic toilet, in accordance with an
embodiment of the invention. As shown in figure 10, the tilting of the U-
shaped bend
(930) at an angle of 90 degree allows the movement of the human waste from the
reservoir (110) to the underground tank (950). The tilting of reverse U-shaped
bend
(930) allows the content of the reservoir (110) to move towards the
underground tank
(950) through the drain pipe (940). In accordance with embodiment of the
invention,
the level of reservoir (110) is higher than that of the underground tank
(950). The
higher level of reservoir (110) allows easy seepage of human waste into the
underground tank (950) through the drain pipe (940). In one embodiment of the
present invention, the drain pipe (940) is provided a slope that inclines the
drain pipe
and provides an easy flow to the human waste from the reservoir (110) to the
underground tank (950).
[0075] Further, when the reverse U-shaped (930) is in horizontal position
(as
shown in figure 9), the human waste is confined inside the reservoir (110)
only. But
when the reverse U-shaped bend (930) is tilted at an angle of 90 degrees (as
shown in
figure 10) the mixture moves towards the underground due to open passage to
the
mixture. In accordance with an embodiment of the invention, the overflow
control
system (900) controls the level of the human waste mixture in the reservoir
(110) and
avoids its overflow into the toilet cabin (160). Further, the reverse U-shaped
bend
(930) is flexibly coupled with the drain pipe (940) with two 90 degree elbows
bends.
The flexible coupling allows tilting of the reverse U-shaped bend (930) to 90
degrees.
Further, the flexible coupling allows easy maintenance and repair of the drain
pipe
(940). Further, the system (900) is capable of flushing the human waste from
the
reservoir (110) to the underground tank (950) and is independent of size of
the
14
CA 3007604 2018-06-07
reservoir (110).
[0076] In
accordance with embodiment of the invention, the underground tank
(950) is one of, but flot limited to a sewage tank, a composting
infrastructure and an
underground dumping site. In accordance with embodiment of the invention, the
human waste is allowed to store in the underground tank (950) such that it can
be used
for manure and fertilizer purposes.
[0077] In
accordance with another embodiment of the invention, the system
(900) for flush and waterless hygienic toilet is connected to the outlet
(1120) of
modem toilets for preventing its overflow and to allow flushing of the human
waste.
Figure 11 illustrates a side view (1100) of overflow control system (900)
connected
with outlet (1120) of the modern toilet (1110), in accordance with an
embodiment of
the invention. Further, the overflow control system (900) prevents the
overflow of the
modem toilet (1100) and allows flushing of the waste without any requirement
of
water.
[0078] Figure 12
illustrates a side view (1200) of human water overflow control
system (900) connected with outlet (1120) of the modem toilet (1110), in
accordance
with embodiment of the invention. As shown in figure 12, the position of the
handle
(920) is shifted that allows the human waste to flush in to the underground
tanks (950),
through the reverse U-shaped bend (930).
[0079] In
accordance with one embodiment of the invention, the system (900) for
flush and waterless hygienic toilet is connected to outlet of dry toilets
having no
availability of water. In one another embodiment, the system (900) is
connected to the
modem toilet (1110) with availability of water. The system is capable of
consuming at
least 50 percent less water as compared to water used by normal modern toilet
having
water based flushing system.
[0080] Further,
the system (900) for flush and waterless hygienic toilet allows
easy and quick cleaning of portable toilet (100). Further, in traditional
chemical based
portable toilets a vacuum system is required to clean the toilet. Further, the
use of the
toilet is flot allowed at the time of cleaning. Further it takes hours to
clean the portable
toilets using the vacuum system and is a cumbersome task. In accordance with
CA 3007604 2018-06-07
embodiment of the invention, the present system (900) takes very less lime to
flush
out the human wastc. Further, in one embodiment it takes only 15 seconds to
flush out
the human waste.
[0081] Figure 13A, 13B and 13C illustrates a side view of the system for
flush
and waterless hygienic toilet, in accordance with another embodiment (1300) of
the
present invention. As shown in Figure 13A, the reservoir (110) includes the
outlet
(910) which is connected with the underground tank (950) in order to directly
pass the
human waste to the underground tank (950). Further, the reservoir (110)
comprises an
ejection bag (1301) adapted to receive the human waste from the hole (130)
provided
on the reservoir cover (120). The ejection bag (1301) may be made of a plastic
or a
rubber etc. A first end (1302) of the ejection bag (1301) is positioned inside
the
reservoir (110) and a second end (1303) of the ejection bag (1301) is extended
to the
underground tank (950). An ejection bag holder (1304) is capable of holding
the first
end (1302) of the ejection bag (1301) using a connection mechanism such as,
but flot
limited to, pins, rivets or the like. Further, the reservoir (110) comprises
an ejection
bag carrier (1305) connected with the ejection bag holder (1304). The ejection
bag
carrier (1305) is adapted to drag the human waste from an outlet (1306) of the
ejection bag (1301) to the underground tank (950). Additionally, the position
of the
handle (220) is moved either automatically or manually from the first position
to the
second position that moves the drawer (210) from under the hole (130) to under
the
first cavity (140) and consequently ejects the human waste to the underground
tank
(950) as shown in Figure 13B. Also, the underground tank (950) is adapted to
store
piles of the human waste which is shown in Figure 13C.
[0082] As can be seen from Figure 13A, the exhaust pipe (1307) is connected
on
one side of the reservoir (110), while the toilet cabin (160) is installed on
one top of
another inside a high rise building. The exhaust pipe (1307) fixed on the one
side of
the reservoir (110) may in itself be a central exhaust pipe of a high rise
building or
may be further connected with a central exhaust pipe (1402) of the high rise
building.
Both the embodiments have been represented in Figure 14.
[0083] In other words, the toilet cabins (160) installed inside the high
rise
building is connected with the central exhaust pipe (1402) fixed from top to
bottom
16
CA 3007604 2018-06-07
outside the high rise building, connecting each toilet cabin (160) of the high
rise
building. Further, one side of the reservoir cover (120), near the exhaust
pipe (1307) is
higher than that of the underground tank (950) adapted to facilitate the flow
of the bad
smell of the human waste from the underground tank (950) to the exhaust pipe
(1307).
It is envisaged that the underground tank (950) may include an opening which
is
connected with the exhaust pipe (1307) in order to direct the flow of the bad
smell of
the human waste to the exhaust pipe (1307). Further, the exhaust pipe (1307)
is
capable of directing the flow of the bad smell of the human waste to the
central
exhaust pipe (1402). The central exhaust pipe (1402) then provides ventilation
and
capable of evacuating the bad smell of the human waste out of the high rise
building.
It is contemplated herein that the underground tank (950) may be converted to
a cold
chamber wherein the human waste may be frozen to neutralize the bad smell of
the
human waste and the visual impacts. Further, the underground tank (950)
comprises a
plurality of compartments adapted to maintain an air quality inside the high
rise
building. In various embodiments, the plurality of compartments comprises, but
not
limited to, a first cold chamber adapted to freeze the human waste for easier
maintenance and a second chamber connected with the exhaust pipe (1307)
adapted to
receive the human waste from the ejection bag (1301).
[0084] ln this manner, in high rise buildings, each apartment can have its
own
storage tank with the waterless hygienic toilet (100), the flush toilet can
allow
multiple users with only two or three gallons of water before flushing: one
flushing a
day system. Furthermore, the flush hygienic toilet also allows one evacuation
pipe for
the liquids mixture to the underground tank (950) and the one central exhaust
pipe
(1402) for bad smell for the ail building. The flush toilet system is
achievable with an
economy of 90% less water with the current invention, especially in high rise
building
where gray water is used.
[0085] Figure 15A, Figure 15B, Figure 15C and Figure 15D illustrate side
views
of the system for flush and waterless hygienic toilet, in accordance with yet
another
embodiment (1500) of the present invention. As shown in Figure 15A, the
exhaust
pipe (1307) is connected on top of the reservoir (110) while the portable
toilet (100) is
installed inside a main floor. As mentioned above, one side of the reservoir
cover
(120), near the exhaust pipe (1307) is higher than that of the underground
tank (950)
17
CA 3007604 2018-06-07
adapted to facilitate the flow of the bad smell of the human waste from the
underground tank (950) to the exhaust pipe (1307). It is envisaged that the
underground tank (950) may include an opening which is connected with the
exhaust
pipe (1307) in order to direct the flow of the bad smell of the human waste to
the
exhaust pipe (1307). Further, the exhaust pipe (1307) is adapted to provide
ventilation
and is capable of evacuating the bad smell of the human waste out of the main
floor.
[0086] Referring to Figure 15B, the toilet cabins (160) installed inside
one or
more floors is connected with the single exhaust pipe (1307) fixed across the
one or
more floors, connecting each toilet cabin (160) of the one or more floors. The
exhaust
pipe (1307) may also be connected on the one sicle of the reservoir (110),
while the
toilet cabin (160) is installed inside the main floor as shown in Figure 15C.
[0087] As shown in Figure 15D, the exhaust pipe (1307) is connected on the
one
side of the reservoir (110) while the toilet cabin (160) is installed inside
the one or
more floors. It is envisaged that the single exhaust pipe (1307) fixed on the
one or
more floors may further connected with the central exhaust pipe (1402) (shown
in
Figure 14) fixed outside the one or more floors, connecting each toilet (160)
cabin of
the one or more floors.
[0088] The portable toilet (100) describcd through various embodiments
above
have number of other advantages such as the blocking the view of the human
waste
while entering inside the toilet cabin (160). Further, providing an efficient
and
innovative ventilation system that improves the environment of the portable
toilet
(100) by directing the bad smell of the human waste away from the toilet
cabin.
Further, the portable toilet (100) is sealed and does flot allow any human
waste smell
to linger around the toilet cabin. This provides the portable toilet (100)
with a healthy
and hygienic environment inside the toilet cabin (160). Further, in the
portable toilet
(100) no water is used and even no usage of harmful chemicals for disinfecting
the
human waste reservoir is required.
[0089] The design of portable toilet (100) provides same level of comfort
and
convenience as using a modem toilet. Further, the portable toilet (100) works
in both
ways as a simple men's urinal for liquid waste clearance and even for solid
waste
clearance. The portable toilet (100) will prove very helpful for using in
remote
18
CA 3007604 2018-06-07
location outdoor events, mountains, roadsides and temporary settlements etc.
Further, the system (900) for flush and waterless hygienic toilet increases
the storage
capacity of the portable toilet (100). The system allows the usage of portable
toilet
(100) for longer duration by a mass crowd without daily maintenance regardless
the
number of users. Additionally, the system allows the user to flush the
waterless
hygienic toilet once in a day. Also, the system for flush and waterless
hygienic toilet is
achievable with an economy of approx. 90% fess water as compared to
traditional
toilets, mainly in the high rise building where gray water is used.
