Description
FIELD OF THE INVENTION
[0001] The invention relates generally to automatically controlled
showers and sinks
BACKGROUND OF THE INVENTION
[0002] We all use water for many purposes, but many of us do not
realize how much water we actually utilize out of the running water
from the tap or shower head in the wash basin. If we define the
optimum use of water is the full direct contact between the user
and the water, then we can really see how much water we do really
waste out of the quantity we think that we are using. In order to
realize this point more, let us consider that a person is drinking
water from a glass or bottle. In this case all the water is 100% in
contact with the body (the mouth) and we can say that this person
is utilizing 100% of the water he is using (drinking in this
case).
[0003] Another opposite example is to consider that a person
washing his face using a bar of soap. He opens the tap, wets his
face, and starts foaming by rubbing the soap bar between his hands
first and then applying it onto his face. Then after some time, he
goes back to the running water and starts rinsing his face with
many handfuls of water before he shuts off the tap. The question
is: does this person utilize all the water running out of the tap
for which he/she pays money for? Obviously, the answer is no. In
fact, a majority of the water running out of the tap is actually
not used because it does not contact the user.
[0004] Similarly when a person takes a shower and opens the water
through any and all existing shower heads, he wets himself first
and then steps away from underneath the shower path and starts
soaping and/or shampooing. Finally he comes back underneath the
shower flow to rinse off his body. The soaping and shampooing time
could reach to up to 60% or more of the shower time. In both
examples the running water during soaping and shampooing is a waste
of both water and energy. One cannot realize how much water he
wastes until he watches himself closely when using water as in the
above three examples.
[0005] A majority of existing taps in public places such as malls
and airports can be automatically switched to either open or
closed, but those automatic "open/close" taps are not suitable and
comfortable in many applications like showers, kitchens and in
private home wash rooms. Also shutting of the water is not
acceptable in many applications, especially in showers because we
still need to use some water while we soap and shampoo. Similarly,
in kitchens and other places, where water is still needed during
scrubbing and/or soaping, automatic "open/close" taps are not
practical in many applications.
[0006] We may realize that most of the water is just flown without
using it as intended. The water that is being in full contact with
the body or any item that is being washed is 100% utilized, but the
rest of water that is not in full direct contact with the body or
item is a waste of both water and energy. When we talk about water
consumption or saving, we talk about energy as well, as energy is
always associated with water. Besides the direct energy to heat the
water we use, energy is used in many stages of water process before
we receive it in that small tab. Energy is used to pump water to
treatment facilities, within the treatment facilities, and after
treatment where it is used to pump water until it reaches its final
outlet location. Also energy is used in the other cycle of water,
which is called waste water treatment, as a result of our use. In
other words, most people do not realize energy consumption related
to used water where more energy is used to treat waste water, and
that is why the water provider companies bill us for double of the
water meter readings. So if we waste water, we actually waste both
energy and water, and when we save it, we do save both of them. An
improved device or system for delivering water to a wash basin
which maximizes the efficient use of the water would therefore save
both energy and water.
SUMMARY OF THE INVENTION
[0007] In accordance with one aspect of the present invention,
there is provided a water flow delivery system for delivering wash
water to a person at a wash basin in such a way that only the
minimum required amount of water is delivered. The water flow
deliver system includes a main water supply line and a branch joint
for dividing the main water supply line into a low flow water line
and a high flow water line. The high flow water line is coupled to
a high flow water outlet and the low flow water line coupled to a
low flow water outlet, both at the wash basin. A first electrically
operated valve is coupled to the high flow water line between the
high flow water outlet and the branch joint, the first electrically
operated valve switchable between an off state wherein water is
prevented from flowing through the high flow water line and an on
state wherein the water is permitted to flow through the high flow
water line. A second electrically operated valve is coupled to the
low flow water line between the low flow water outlet and the
branch joint, the second electrically operated valve switchable
between an off state wherein water is prevented from flowing
through the low flow water line and an on state wherein the water
is permitted to flow through the low flow water line. The system
also includes a control unit for selectively activating the first
and second electrically operated valves, the control unit
configured to switch between a fully off state wherein both the
first and second electric control valves are in the off state, a
high flow state wherein the first electric valve is in the on state
and the second electric valve is in the off state and a low flow
state wherein the first electric valve is in the off state and the
second electric valve is in the on state.

DETAILED DESCRIPTION OF THE INVENTION
[0025] Referring to FIGS. 1, 2, 3 and 4 the core of the present
invention consists of a water flow splitter unit 10 which consists
of a housing 12 having an intake port 14, a high flow outlet port
16 and a low flow outlet port 18. First electrically controlled
valve 20 is positioned adjacent high flow outlet port 16 and
controls the flow of water passing through the high flow outlet
port. Second electrically controlled valve 22 is positioned
adjacent low flow outlet port 18 and controls the flow of water
passing through the low flow out let port. High flow outlet port 16
has an internal diameter 24 and low flow outlet port 18 has an
internal diameter 26. Internal diameter 24 is made significantly
greater than internal diameter 26 to ensure that port 16 has a much
greater flow capacity relative to port 18. Preferably, internal
diameter 24 is sufficiently greater than internal diameter 26 so
that the flow of water through port 18 is much lower percentage
(roughly 10% as an example) of the flow of water through port 16,
while port 16 is capable of handling 100% of the flow capacity of
intake port 14. It should be pointed out that if greater or lesser
flow is required from outlet port 18, the dimensions of diameter 26
can be changed; however, the goal is to ensure that the flow out of
port 18 is a small fraction of the flow out port 16. Housing 12
could be made of any material suitable for use in municipal water
lines such as brass or high grade plastic. Each of ports 14, 16 and
18 are provided with standard plumbing fixtures to make their
attachment to standard plumbing lines convenient. While housing 12
is illustrated as cylindrical, housing 12 could be any shape
provided that ports 14, 16 and 18 are provided with standard
plumbing fixtures. Furthermore, it is not strictly necessary to
have port 18 at 90.degree. to port 18 as housing 12 could be formed
as a Y joint (or any other suitable configuration).
[0026] Referring now to FIGS. 5a through 7b, electrically
controlled valves 20 and 22 each control the flow of water through
their respective ports. Valve 20 has closure member 28 which can be
positioned between a fully opened position as shown in FIGS. 5a and
7a wherein water is free to flow through port 16 and a fully closed
position as shown in FIGS. 5b and 7b wherein water cannot flow
through port 16. Likewise, valve 22 has closure member 30 which can
be positioned between a fully opened position as shown in FIGS. 5b,
6b and 7b wherein water is free to flow through port 18 and a fully
closed position as shown in FIGS. 5a, 6a and 7a wherein water
cannot flow through port 18. Valves 20 and 22 may consist of
selectively adjustable butterfly type valves as illustrated, or
they may consist of solenoid type plunger valves. Butterfly type
valves (and ball valves) can be set to any flow rate such as 100%
(fully open), 75%, 50%, 25% etc. Solenoid valves are much less
expensive, are highly reliable and can be switched between two
states, namely fully opened and fully closed. Ball type valves may
also be used. A variety of electrically operated butterfly and ball
valves and a variety of solenoid type valves are easily available
in the market.
[0027] When first valve is in its open position at the same time
that the second valve is in its closed position, then splitter 10
is said to be in its high flow state wherein water will flow
entirely through high flow port 16 and not through port 18 (see
FIGS. 5a and 7a. When first valve 20 is in its closed state and
second valve 22 is in its open state then splitter 10 is in its low
flow state wherein water flows entirely through low flow port 18
and not through port 16 (see FIGS. 5b and 7b).
[0028] As seen in FIG. 9, splitter 10 is used as part of a system
which includes a control unit for controlling the flow of water to
a wash basin. Splitter 10 is shown schematically in FIG. 9 as its
constituent parts, namely ports 14, 16 and 18 and valves 20 and 22.
Intake port 14 is coupled to main water line 32 by means known
generally in the art. Valves 20 and 22 are coupled to control unit
42 via cables 48 and 50, respectively. Valves 20 and 22 are
normally closed valves and switch into their open state only when
activated by control unit 42. Control unit 42 consists of a control
board having circuits for automatically activating valves 20 and
22. Preferably control unit 42 consists of a PLC (programmed logic
controller) or a controller board including a combination of
microcontroller and relays. It is possible to build control unit 42
out of any standard microcontroller--indeed, an Arduino.TM. or
equivalent board in combination with a relay array could be used to
construct control unit 42. Control unit 42 is supplied with
electrical power via transformer 44 which is plugged into an AC
power outlet. High flow water line 34 is coupled to outlet 16 by
means known generally in the art. A high flow water outlet 36, such
as a standard shower head, is coupled to an end of water line 34
opposite outlet 16. A low flow water outlet 40, such as a small
shower sprinkler, is coupled to an end of low flow water line 38
opposite outlet 18. Low flow water outlet 40 is positioned a short
distance away from high flow water outlet 36 (say by a foot or
two). Proximity sensors 44 and 46 are coupled to control unit 42 by
cables 52 and 54, respectively. Proximity sensor 44 is positioned
adjacent outlet 36 and is oriented to sense the presence of objects
in front of outlet 36 while proximity sensor 46 is positioned
adjacent outlet 40 to sense the presence of objects in front of
outlet 40. Proximity sensors 44 and 46 may comprise Infra red
sensors or ultra sonic sensors. Proximity sensor 44 and control
unit 42 are calibrated so that when a person stands in front of
sensor 36, the sensor sends a signal to control unit 42 which in
turn activates valve 20. Likewise, proximity sensor 46 and control
unit 42 are calibrated so that when a person stands in front of
sensor 46, the control unit activates valve 22. Hence, a user in a
shower can switch control unit 42 from a high flow state to a low
flow state by simply moving from a position directly in front of
shower head 36 to a position away from shower head 36 and in front
of outlet 40. The user can trigger control unit 42 into the high
flow state by simply stepping back in front of shower head 36. A
button or switch 56 can be coupled to control unit 42 by a cable 58
for switching control unit 42 into a closed state wherein the
control unit de-activates (i.e. closes) valves 20 and 22. Control
unit 42 is preferably configured such that activating button/switch
56 will place the control unit an active mode (either high flow or
low flow) depending on the location of the person in the shower
stall.
[0029] In this arrangement the main water flow enters the splitting
device (10) at port 14. If a person is in a shower and stands
underneath the main water flow shower stream, proximity sensor 44
will signal the control unit and activate the system to open the
large electric valve 20 to let the normal flow goes through at
outlet port 16, while the smaller flow electric valve 22 is closed.
Once the person moves away from proximity sensor 44 (away from the
normal flow), proximity sensor 46 signals the controller unit to
close the normal flow valve 20 and opens the smaller flow valve 22
simultaneously, and the water will go through outlet 40 at 10% flow
rate of the normal water flow (or at whatever percentage port 18 is
configured to carry). This smaller flow outlet will be located away
from the center where the normal flow path is. In this case the
person who takes a shower can use this smaller flow at this
convenient location to use or wet out while soaping and shampooing,
provided that he does not stand in the main flow path. It is
possible to obtain substantially the same result with only one
proximity sensor; however, greater reliability and control cab be
achieved using two proximity sensors. While infrared sensor eye
detectors are used to activate the system in showers, a step on mat
with proximity detectors can be used to activate the systems for
both flows in showers as required by any specific application (as
shown in FIG. 11).
[0030] Furthermore, by using a PLC (programmable logic controller)
or some other sort of microcontroller based control unit, the
system can be designed to further do more saving alternatives
(programs) as required by each specific application. The following
example programs are described: note, these programs are based on
the assumption that an average shower time is 15 minutes, of which
10% is for wetout, 60% for soaping and shampooing and 30% is for
rinsing. These programs include, but not limited to the
following:
Saving Program 1:
[0031] A person starts his shower and stands underneath the normal
flow path where the normal flow proximity sensor senses. The normal
(high) flow valve 20 opens normally at full while the smaller flow
(10% of the normal flow) valve (22) is closed. When the person
steps away from the normal flow, the normal valve closes and the
smaller valve opens in full until the person steps back underneath
the normal flow where the rays from the normal flow infrared eye
are broken again. Then the normal flow electrical valve opens and
the smaller flow electrical valve closes and so on until the person
closes the main tap. In this program, we can reduce 90% of the 60%
of water being used during shower time. This means that we save 54%
of the water and energy used during shower time.
Program 2:
[0032] Same as (1) above except to swing the smaller valve shaft
between "open" and "close" positions (each one or two seconds for
example) to further reduce the small flow by extra 5% of the normal
flow, while the user will use it at 10% of the normal flow. In
other words, if the smaller flow flows at continuous rate of 10% of
the normal flow and we set the controller to open and close the
smaller valve shaft (at each one or two seconds for example), then
the flow will be in sort of pulses of water flows and the user will
not miss the flow, since it will be back each 1 or 2 seconds. By
doing this, we will reduce the flow during soaping and shampooing
to only 5% of the normal flow, while the user is still getting the
water to wet out at rate of 10% of the normal flow. This means we
can reduce by an extra 3% the total water and energy consumed, for
a total saving of about 57%.
Program 3:
[0033] When a person starts his shower and the normal flow valve 20
opens for wet out, we will set the controller is set so that valve
20 opens at 75% instead besides the saving in this program program
(2) above. In this program, the will be a savings of 25% of the
10%, so the additional savings by this program is 2.5% and the
total savings will be 59.5%.
Program 4:
[0034] Same as saving program (3) above, except valve 22 opens at
50% instead of 75% during wet out. In this program, there will be
additional saving of 2.5% for a total saving of 62%.
Program 5:
[0035] All saving programs from 1 to 4, except that we set the
controller so the normal (high) flow valve opens fully during the
rinsing stage for certain time (1.5 minutes for example) and then
closes to three quarters full until the end of rinsing time. In
this program, and addition 5% is added for a total savings of
67%.
Program 6:
[0036] All saving programs from 1 to 5 except the normal flow valve
shaft opens fully during the rinsing stage for certain time (1.5
minutes for example) then closes to three quarters full for same
time (1.5 minutes), and then closes to 50% opening until the end of
rinsing stage. In this program we add an additional 7.5% to the
total savings, for a total of 74.5%.
Saving program 7:
[0037] All saving programs from 1 to 5, except the normal flow
valve shaft opens fully during the rinsing stage for certain time
(1.5 minutes for example), then closes to three quarters full for
same time (1.5 minutes), then closes to 50% opening for 1.5 minutes
only, and then the system closes and will not open until the person
gets out of the bath and comes back again.
Saving program 8:
[0038] It is also possible to configure the controller to record
the number of times the system is activated and send this
information to any terminal to enable the management to control the
water usage properly and efficiently. This program can be used in
hotels, lodges, hospitals, rental units, multiple floors house, a
single house, and any other application. Also in a hotel or any
other application, we may include more than one program to choose
from for each user (or client) in the same room. For example, one
client will pay only for the basic which is one of the programs
mentioned above or alike and only for one time shower during his
stay, while other client wants to have two showers during his stay
and so on. These choices can be added to each application mentioned
above either in the main control room or by individual touch screen
with printed boards (as explained below in "other uses") and can be
available in each shower room. This saving option will further
increase the total savings of both water and energy for each end
user and will allow each hotel for example to compete in their
industries and add more savings if they want so. In general we can
do any applicable saving program with our system that a certain
application requires.
[0039] These saving programs are just examples of what this system
can do. In reality, we can do any and all saving programs the
system can be set at. Also the times mentioned are just examples.
For each application, we will design different program(s). Even
though the (FIGS. 9 to 12) below show just one single network
(shower, or sink), in larger applications with more than one
networks (shower, sink, or alike) we will use one main controller
and transformer to control all networks such as shower(s),
kitchen(s), sink(s) and so on. For example in a hotel we will use
only one control unit and one transformer to control all networks
unless otherwise required.
[0040] Other Uses:
[0041] For other uses as in kitchens, sink faucets, and all similar
applications, we can set up our system in any way to suit any
specific application. Essentially the same system as illustrated in
FIG. 9 and discussed above could be set up in a kitchen and bath
room sink faucet arrangement as illustrated in FIG. 10 wherein a
large (normal) flow outlet faucet 136 coupled to high flow water
line 134 is coupled to port 16 of splitter 10 and a low flow outlet
(faucet) 140 is coupled to a low flow water line 138 which is in
turn coupled to port 18 of the splitter. Proximity sensors 144 and
146 are coupled to control unit 42 by cables 152 and 154,
respectively. This arrangement would work as in the previous
embodiment to permit the user to activate faucets 136 or 140 simply
by positioning his/hands under the respective faucet so as to
activate the appropriate proximity sensor. This mechanism can be
repeated as many times as may be needed.
[0042] As best seen in FIG. 11 it is also possible to use a
pressure sensitive mat 80 with embedded pressure switches in place
of proximity sensors. The user can simply step on mat 80 to send a
signal via cable 85 to control unit 42 which then activates the
appropriate valves to cause water to flow to either taps 136 or 140
depending on where the user steps on the matt. As also illustrated
in FIG. 12, it is also possible to replace the proximity sensors
with a touch screen or control panel 90 having a plurality of
buttons or touch keys 94 which are operatively coupled to control
unit 42 via cable 92.
[0043] The system as illustrated in FIG. 12 can be set up with many
saving options for sink applications with each button 94 activating
a different preprogrammed sequence (saving programs) in control
unit 42. These saving programs will be set up in different choices
for the user to choose from. For example, we can use the touch
screen to activate any program in our system, so the user can
choose the desired flow by touching the labeled button. For
example, we divide the touch screen into two vertical sections, one
section for smaller flow (from tap 140) and the other one for the
normal flow (from tap 136). In each section there could be any
number of touch keys and each touch key could be set for certain
valve openings. For example, let us assume that the smaller flow in
our Splitting Device is designed to transport 20% of the normal
flow, we can program the keys to control the following functions
from the low flow tap (tap 140): [0044] 1--First touch key opens
the low flow valve fully to get 20% flow. [0045] 2--Second touch
key opens the low flow valve at 75% to get 15% of the normal flow.
[0046] 3--Third touch key opens the smaller flow valve at 50% to
get 10% of normal flow. [0047] 4--Fourth touch key opens the valve
at 50% and swings the shaft between "close position" and "50% open
position" each one or two seconds to get pulses of water at 10% of
total water flow, but with saving of 95% of total normal flow.
[0048] 5--Fifth touch key opens the valve at 25% to get 5% flow of
water with savings of 95% of the normal flow. [0049] 6--Sixth touch
key opens the valve at 25% and pulses the valve between "close
position" and "25% opening position" for each one or two seconds,
so we get pulses of water flow at 5% of normal flow for each one or
two seconds at rate of 5%, and we save 97.5% of normal flow.
[0050] We can label the six touch keys as per specific application
as it will be different from a kitchen sink faucet to bathroom's
sink faucet and so on. The same (or similar) set of functions can
be applied to the keys/buttons controlling the flow of water from
the large flow tap 136. For example: [0051] 1--First touch key
opens the normal flow valve at full, so we get 100% of normal flow
[0052] 2--Second touch key opens the normal flow valve at 75% to
get 75% of normal flow and save 25% of normal flow. [0053] 3--Third
touch key pulses the valve in (2) above between "closed position"
and "75% open position" each one or two seconds, so we get pulses
of flow at 75% of normal flow, and we save 62.5% of the normal
flow. [0054] 4--Fourth touch key opens the normal flow valve at
50%, so we get 50% flow and save 50% of the normal flow [0055]
5--Fifth touch key pulses the valve as in (4) above between "closed
position" and "50% opening" position at each one or two seconds, so
we get pulses of water flow at 50% of normal flow each one or two
seconds and we save 75% of normal flow. [0056] 6--Sixth touch key
opens the valve at 25% to get steady flow of 25% and save 75%
[0057] 7--Seventh touch key pulses the valve in (6) above between
"closed position" and "25% open" position each one or two seconds,
so we get pulses of water flow at 25% of the normal flow and we
save 87.5% of normal flow.
[0058] We can also label these touch keys (for example) as
following:
[0059] 1-heavy rinsing
[0060] 2-semi heavy rinsing
[0061] 3-Economy rinsing
[0062] 4-Medium rinsing
[0063] 5-Light medium rinsing
[0064] 6-Saving rinsing
[0065] 7-ultra saving rinsing
[0066] On the same touch screen we can make another touch key and
label it "Pause"
[0067] This "Pause" touch key can stop any active flow for a while.
So if a user wants to shut off the water for a while, he just
pushes this "Pause" touch key once and the system stops until he
touches the same "Pause" key again, and the system will continue
with the same previous touch key flow.
[0068] In this system, the user can go back and forth from one
touch key to another by just touching any other touch key, either
between same flow keys, or between smaller flow and normal flow
keys. However, if the main manual tab is still valid and the user
shuts it off the system will close and does not open until the main
tap is turned on manually. However, if no manual valve (tap) is in
the system, the "Pause" key will be the main turn "ON" and "OF"
[0069] These saving programs are just examples and we can program
our system as we want and the specific application requires
including, but not limited to the time setting, percentage of
openings, closing time, and any and all applications and programs
that can be set with our system. All these functions and programs
that can be set up in our system are part of our patent.
[0070] Finally and even though it is not foreseen to be needed, our
system can be upgraded to split water into more than two flows if
required based on the same principles with additions of openings
and electrically controlled valves. Also based on the multi flow
functions in each flow, it may be downgraded to only one flow with
programmed functions if required by specific application.
