BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates generally to a method and apparatus for purifying and dispensing water, and more particularly to a portable system for making purified drinking water from municipally treated water, and thereafter dispensing the drinking water.
2. Description of Related Art The bottled drinking water industry is a worldwide multi-billion dollar industry. Health conscious consumers are purchasing bottled drinking water in record numbers and that trend is expected to continue.
Typically, bottled drinking water is sold in grocery stores.
Virtually all such bottled water is supplied to grocery stores by remotely located bottle water manufacturers, thereby requiring transportation of the bottled water from the remote location to a particular grocery store location. Obviously, such transportation entails undesirable costs and requires the grocery stores to maintain storage space for inventory.
2~ J~
Purchasing bottled water from bottle water manufacturers is disadvantageous for grocers for a number of reasons. One disadvantage is that grocers must estimate the amount of bottled water required for their periodic needs and order accordingly.
S Underestimating results in out-of-stock situations and overestimating results in excess inventory. Another disadvantage is that the grocery store must bear the often substantial cost of shipping the bottled water from the bottled water manufacturer's location to the its location. Once delivered, the bottled water must then occupy valuable retail shelf space and/or warehouse space. A further disadvantage is the problem of disposing of unpurchased bottled water.
The present invention relates to on-site manufacture of bottled drinking water for grocery stores. The invention comprehends both purification and dispensation technology.

Purifying the water includes filtering the water through a set of filters, radiating the water with ultraviolet light (in the first embodiment), step 206, and ozonizing the water, step 208.
Dispensing the water includes manually dispensing the water into a 2~
container, step 210, automatically dispensing the water into a container, step 212, or spraying the water, step 214.
Water is supplied from the water source into the water inlet port, step 216. As used herein, the term "heavy water" means water containing dissolved iron or manganese. If the water is not heavy water, condition 228, solid particles having a diameter of greater than or equal to approximately 5 microns are filtered from the water, step 218. If the water is heavy water, d.issolved metals tferrous matter) are removed from the water with a metals filter, step 230, and the process continues with step 220. Chemical and metal contaminants, such as chlorine, herbicides, pesticides, trihalomethanes, iron, lead, manganese, hydrogen sulfide, and mercury, are then removed from the water by filtering the water through a carbon media bed, step 220. Solid particles having a diameter of greater than or equal to 1 micron and less than 5 microns are then filtered from the water, step 222. In one embodiment of the process (condition 226 is "Yes"~, bacteria and viruses are thereafter removed from the water by radiating the water with ultraviolet light, step 206, and particles, bacteria and viruses having a diameter of greater than or equal to .2 microns and less than 1 micron are filtered from the water, step 224. In another embodiment of the process (condition 226 is "No"), the process continues with step 208. Ozone is introduced into the water to provide ma~imum sanitizing of the water, step 208. Upon completion of the purification process, the purified water is manually dispensed into a container, step 210, automatically dispensed into a container, step 212, or sprayed, step 214.
The process step for automatically dispensing water into the container 94', step 212, includes providing the container 94' in which to dispense the water; instructing a user of the apparatus 12' to place the container 94' in the holder 97' beneath the dispenser 90'; automatically sensing the presence of the container 94' in the holder 97' and automatically instructing the user of the ~r~f~.7~
apparatus 12' to start the dispensing process; automatically dispensing an appropriate amount of water; and advising the user upon completion of the process to place a cap on the container 94' and to remove the container 94' from the holder 97'.
As shown in Figure 15, automatically dispensing the water includes a start state 250. Start state 250 includes three modes:
operation mode; instruction mode; and heuristic mode. The default mode is the operation mode which facilitates dispensing of water into the container 94'. Upon enabling the apparatus 12' by turning the on/off switch 154' on, the control device 158' monitors the status of the first sensor 162' and a determination 252 is made as to whether the dispenser door 168' is open. If the first sensor 162' indicates that the door 168' is open, then first visual and aural messages are conveyed to the user to prepare and load a container 94' to be filled with water, step 254. The first visual message comprises enabling the first LED 17Oa'. In addition, the voice generator 174' issues an appropriate aural message through the speaker 172'. If the door 168' is closed, the first sensor 162' is repeatedly tested until the door 168' is opened, step 292.
After conveying the first messages to the user, a determination 256 is made using the second sensor 164' as to whether the container 94' has been appropriately loaded into place. If so, the first visual message is removed (i.e., the LED is turned off) and second visual and aural messages are conveyed to the user to close the dispenser door 168', step 258. The first sensor 162' is then used to determine whether the door 168' has been closed in response to the ;econd messages. If the door 168' has been closed, then the second visual message is removed and third visual and aural messages instruct the user to press the second button 166', step 260. If the door 168' has not been closed, then the first sensor 162' is tested until the door 168' is closed. Upon pressing the second button 166', a determination 264 is made as to whether the ozonizer 30' is operational. If the ozonizer 30' is not operational, step 264, the apparatus 12' is taken out of service and sixth visual and aural messages so inform the user, step 294.
The sixtll visual message preferably involves the control device 158' enabling the sixth LED 170f'. If the ozonizer 30' is operational, the ozoni~er 30' is started and the solenoid valve 156' Gpened.
In the operation mode, the timer 158e' is then started, step 282, and a message is communicated to the user, step 284.
Typically, the message is a commercial message. Once the time period defined by the timer 158e' has expired, the solenoid valve 156' is closed, the ozonizer 30' is stopped, and the third visual message is removed. Fourth visual and aural messages then instruct the user to cap the container 94' before removing the container 94' from the apparatus 12', step 288. If the second sensor 164' indicates that the container 94' has been removed, then the fourth visual message is removed and fifth visual and aural messages are issued thanking the user, step 290. The apparatus 12' is then reset to the start state 250 in preparation for another container filling cycle. At certain test points in the process (viz., 252, 256, and 262), a determination 292 is made concerning whether the test has been performed for longer than a predetermined timeout period. If so, the apparatus 12' is reset. If not, the test is performed again.
As a preferred alternative to the above described sequence, the first, second, and third aural messages may instead be generated upon pressing the first button 160'. Upon receiving a signal from the first button 160', the control device 158' enters intG an instruction mode. In the instruction mode, the first, second, and third aural messages are heard by the user only upon the user's request, by pressing the first button 160' at the beginning of the process, 250, and are not heard during process steps 254, 258, and 260, respectively.
r~ ~J 8 Another aspect of the automatic dispenser 34' is a heuristic mode which permits the dispenser 3~' to be "taught" what amount of water to be dispensed into the container 94'. The control device 158' includes a heuristic mode switch 158f' which, upon being enabled, places the apparatus 12' in heuristic mode. Control device 158' facilitates performance of the same sequence of steps normally associated with the operation mode, with a few important exceptions. If the heuristic mode switch has been enabled, then the process flow follows the "Yes" path at step 270, namely, monitoring the flow of water via the flow meter 146'. The second button 166' may be depressed and released one or more times thereby signalling the control device 158' to start and stop the flow of water. The flow meter 146' communicates to the control device 158' information corresponding to the aggregate amount of water which flowed through the flow meter in response to pressing the second button 166'. Monitoring of the flow of water continues until the second sensor 164' indicates that the container 94' has been removed. Once the container 94' has been removed, storing means 158b' contains information which defines the volume of water desired to be dispensed in the operation mode. That information is then used in the operation mode by the timer 158e' to determine when to cease filling the container 94'.

Purifying means contained within the housing 38 preferably includes a set of filters, an ultraviolet radiation device 28, and an ozonizer 30, as shown in Figure 5. The set of filters includes a first filter 108, a second filter 110, a third filter 112, and a fourth filter 114. Preferably, each filter has an associated pressure gauge 116a, 116b, 116c, and 116d for monitoring water pressure. Each pressure gauge 116 is integral with its associated filter and is provided with a pressure release mechanism or safety valve 118a, 118b, 118c, and 118d.
The first filter 108, preferably a 5 micron filter, is mounted within the housing 38 and connects to the water conduit 18 between the water inlet port 16 and the second filter 110. The first filter 108 is a pre-stage filter for removing sludge, sand, sediment, rust and undissolved particles from the water.
Preferably, solid particles having a diameter of greater than or equal to 5 microns are removed from the water with the 5 micron filter 108 housed in a first filter housing 122, such as a 20 inch AMETEC filter housing, manufactured by Ametec, Inc. of Sheboygan, Wisconsin.
The second filter llO, preferably a carbon filter, is mounted within the housing 38 and connects to the water conduit 18 between the first filter 108 and the third filter 112. Chemical and metal contaminants, such as chlorine, herbicides, pesticides, trihalomethanes, iron, lead, manganese, hydrogen sulfide, and mercury, are removed from the water by passing the water through the carbon filter 110. Preferably, the carbon filter 110 is a granular activated filter within a 20 inch second filter housing 126.
2~7~7(~
The third filter 112, preferably a 1 micron filter, is mounted within the housing 3~ and connects to the water conduit 18 between the second filter 112 and the ultraviolet radiation device 28.
Preferably, the 1 micron filter 112, contained within a 20 inch 5third filter housing 134, is employed to remove from the water solid particles having a diameter of greater than or equal to 1 micron and less than 5 microns.
The ultraviolet radiat on device 28 is mounted within the housing 38 and connects to the water conduit 18 between the third 10filter 112 and the fourth filter 114. The preferred ultraviolet radiation device 28 is a high performance ultraviolet output device capable of removing approximately 99% of bacteria and viruses. An example of such a unit is the Trojan 608 Plus, manufactured by Trojan Technologies of London, Ontario, Canada.
15The fourth filter 114, preferably a .2 micron filter, is mounted within the housing 38 and connects to the water conduit 18 between the ultraviolet radiation device 28 and a flow meter 146.
Particles, bacteria and viruses having a diameter of greater than or equal to .2 microns and less than 1 micron are removed with the 20.2 micron filter 114, encased within a fourth filter housing 138, such as a 20 inch AMETEC filter housing.
The ozonizer 30 is mounted within the housing 38 and connects to a venturi valve 142 between the flow meter 146 and the solenoid valve 156. The preferred ozonizer 30 is capable of providing up to 252.9 gr/m3 ozone to water using cold spark corona discharge, which provides maximum sanitizing of the water. Such a unit is manufactured by LMK Technolgies, of Monroe, North Carolina. The preferred ozonizer 30 also communicates with an air filtration and dryer mechanism 140.
30The filters employed with respect to the first embodiment of the invented apparatus must be periodically replaced. The frequency of replacement varies depending on usage. In general, the estimated life of the 5 micron filter 108 is 6,000 gallons, the estimated life of the l micron filter 112 is 18,000 gallons, the estimated life of the .2 micron filter 114 is 37,500 gallons, and the estimated life of the carbon filter 110 is 30,000 gallons. A
flow meter 146 is provided in order to measure the amount of water processed through the apparatus 12. A pressure regulator 82 communicates with the water conduit 18 between the double check valve 79 and the set of filters and provides constant pressure within the system, and can be regulated to accommodate an auxiliary connection simultaneously with processing of drinking water (e.g., the sprayer 36). The preferred inlet pressure is 100 psi and the preferred operating pressure is 40 psi.
The ultraviolet radiation device 28 and ozonizer 30 are powered by a power source 150 which supplies power to the two units via a power outlet 152. In the preferred embodiment, the power source 150 is 120 Volt, 20 Amp, single phase circuit. An on/off switch 154 is provided on the apparatus 12 for turning power on and off. In addition, the ultraviolet radiation device 28 and the ozonizer 30 are electrically connected to the solenoid valve 156 which automatically stops the flow cf water through the apparatus 12 in the event either the ultraviolet radiation device 28 or the ozonizer 30 fail to operate.
The first embodiment of the apparatus 12 is primarily intended for bottling purified water by grocery store personnel for production purposes. In a second embodiment, shown in Figures 6 through lO, apparatus 12' is adapted for dispensing purified water into containers to consumers or users of the apparatus 12' upon demand. Water is supplied from a water source 14' into a water inlet port 16' through a water conduit 18' and out of at least one water c,utlet port 20', as shown in Figure 11.

Means 158d' for input and output between the control device and the periph~ral devices is also included.
The first button 160' and the control device 158' are connected such that depressing the first button 160' signals the control device 158' to enter an instruction mode, discussed hereafter. The first sensor 162' is preferably a magnetic door sensor which detects whether a dispenser door 168' is open or closed, and which signals the door status to the control device 158'. The second sensor 164' is preferably an optical photo 2 ~
sensor, such as a Warner Model MCS 653-13 (manufactured by Warner Electric, Inc. of Marengo, Illinois), positioned within the holder 97' and connected to the control device 158', for signalling the presence or absence of a container 94' in the holder 97' to the 5 control device 158'. Visual message means include a set of light emitting diodes (LEDs), 170a', 170b', 170c', 170d', 170e', 170f', positioned on the front 42' the apparatus, which are connected to the control device 158'. Each LED 170' is associated with a textural message 171' appearing adjacent to the LED. Of course, other visual message means may also be employed, such as a video monitor device. Aural message means include a speaker 172' mounted on the front 42' of the apparatus, which is connected to the control device 158', and stored messages which are generated through the speaker 172' in spoken form by a voice generator 174' under the control o the control device 158'. Preferably, the messages are encoded and digitally stored in the storing means 158b' of the control device 158' and may be varied by reprogramming of the control device 158'. However, the control device 158' could also interface with a tape player/recorder or similar device to accomplish a similar result. The second button 166' connects to the control device 158' and signals the control device 158' to commence filling the container 94' with water. The control device 158' regulates the amount of water dispensed in accordance with signals generated by flow meter 146'. Depressing the second button 166' results in a continuous filling of the container 94' for a predete~mined time period.
Figure 14 illustrates the invented method, which includes purifying the water during transit through the water conduit, step 200, and thereafter dispensing the water, step 202. Purifying the water includes filtering the water through a set of filters, radiating the water with ultraviolet light (in the first embodiment), step 206, and ozonizing the water, step 208.
Dispensing the water includes manually dispensing the water into a 2~
container, step 210, automatically dispensing the water into a container, step 212, or spraying the water, step 214.
Water is supplied from the water source into the water inlet port, step 216. As used herein, the term "heavy water" means water containing dissolved iron or manganese. If the water is not heavy water, condition 228, solid particles having a diameter of greater than or equal to approximately 5 microns are filtered from the water, step 218. If the water is heavy water, d.issolved metals tferrous matter) are removed from the water with a metals filter, step 230, and the process continues with step 220. Chemical and metal contaminants, such as chlorine, herbicides, pesticides, trihalomethanes, iron, lead, manganese, hydrogen sulfide, and mercury, are then removed from the water by filtering the water through a carbon media bed, step 220. Solid particles having a diameter of greater than or equal to 1 micron and less than 5 microns are then filtered from the water, step 222. In one embodiment of the process (condition 226 is "Yes"~, bacteria and viruses are thereafter removed from the water by radiating the water with ultraviolet light, step 206, and particles, bacteria and viruses having a diameter of greater than or equal to .2 microns and less than 1 micron are filtered from the water, step 224. In another embodiment of the process (condition 226 is "No"), the process continues with step 208. Ozone is introduced into the water to provide ma~imum sanitizing of the water, step 208. Upon completion of the purification process, the purified water is manually dispensed into a container, step 210, automatically dispensed into a container, step 212, or sprayed, step 214.
The process step for automatically dispensing water into the container 94', step 212, includes providing the container 94' in which to dispense the water; instructing a user of the apparatus 12' to place the container 94' in the holder 97' beneath the dispenser 90'; automatically sensing the presence of the container 94' in the holder 97' and automatically instructing the user of the ~r~f~.7~
apparatus 12' to start the dispensing process; automatically dispensing an appropriate amount of water; and advising the user upon completion of the process to place a cap on the container 94' and to remove the container 94' from the holder 97'.
As shown in Figure 15, automatically dispensing the water includes a start state 250. Start state 250 includes three modes:
operation mode; instruction mode; and heuristic mode. The default mode is the operation mode which facilitates dispensing of water into the container 94'. Upon enabling the apparatus 12' by turning the on/off switch 154' on, the control device 158' monitors the status of the first sensor 162' and a determination 252 is made as to whether the dispenser door 168' is open. If the first sensor 162' indicates that the door 168' is open, then first visual and aural messages are conveyed to the user to prepare and load a container 94' to be filled with water, step 254. The first visual message comprises enabling the first LED 17Oa'. In addition, the voice generator 174' issues an appropriate aural message through the speaker 172'. If the door 168' is closed, the first sensor 162' is repeatedly tested until the door 168' is opened, step 292.
After conveying the first messages to the user, a determination 256 is made using the second sensor 164' as to whether the container 94' has been appropriately loaded into place. If so, the first visual message is removed (i.e., the LED is turned off) and second visual and aural messages are conveyed to the user to close the dispenser door 168', step 258. The first sensor 162' is then used to determine whether the door 168' has been closed in response to the ;econd messages. If the door 168' has been closed, then the second visual message is removed and third visual and aural messages instruct the user to press the second button 166', step 260. If the door 168' has not been closed, then the first sensor 162' is tested until the door 168' is closed. Upon pressing the second button 166', a determination 264 is made as to whether the ozonizer 30' is operational. If the ozonizer 30' is not operational, step 264, the apparatus 12' is taken out of service and sixth visual and aural messages so inform the user, step 294.
The sixtll visual message preferably involves the control device 158' enabling the sixth LED 170f'. If the ozonizer 30' is operational, the ozoni~er 30' is started and the solenoid valve 156' Gpened.
In the operation mode, the timer 158e' is then started, step 282, and a message is communicated to the user, step 284.
Typically, the message is a commercial message. Once the time period defined by the timer 158e' has expired, the solenoid valve 156' is closed, the ozonizer 30' is stopped, and the third visual message is removed. Fourth visual and aural messages then instruct the user to cap the container 94' before removing the container 94' from the apparatus 12', step 288. If the second sensor 164' indicates that the container 94' has been removed, then the fourth visual message is removed and fifth visual and aural messages are issued thanking the user, step 290. The apparatus 12' is then reset to the start state 250 in preparation for another container filling cycle. At certain test points in the process (viz., 252, 256, and 262), a determination 292 is made concerning whether the test has been performed for longer than a predetermined timeout period. If so, the apparatus 12' is reset. If not, the test is performed again.
As a preferred alternative to the above described sequence, the first, second, and third aural messages may instead be generated upon pressing the first button 160'. Upon receiving a signal from the first button 160', the control device 158' enters intG an instruction mode. In the instruction mode, the first, second, and third aural messages are heard by the user only upon the user's request, by pressing the first button 160' at the beginning of the process, 250, and are not heard during process steps 254, 258, and 260, respectively.
r~ ~J 8 Another aspect of the automatic dispenser 34' is a heuristic mode which permits the dispenser 3~' to be "taught" what amount of water to be dispensed into the container 94'. The control device 158' includes a heuristic mode switch 158f' which, upon being enabled, places the apparatus 12' in heuristic mode. Control device 158' facilitates performance of the same sequence of steps normally associated with the operation mode, with a few important exceptions. If the heuristic mode switch has been enabled, then the process flow follows the "Yes" path at step 270, namely, monitoring the flow of water via the flow meter 146'. The second button 166' may be depressed and released one or more times thereby signalling the control device 158' to start and stop the flow of water. The flow meter 146' communicates to the control device 158' information corresponding to the aggregate amount of water which flowed through the flow meter in response to pressing the second button 166'. Monitoring of the flow of water continues until the second sensor 164' indicates that the container 94' has been removed. Once the container 94' has been removed, storing means 158b' contains information which defines the volume of water desired to be dispensed in the operation mode. That information is then used in the operation mode by the timer 158e' to determine when to cease filling the container 94'.
