Abstract
A portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants includes a portable, refillable and hand-holdable vessel for holding and pouring water having a spout and, inside the portable, refillable and hand-holdable vessel, moving water and still water processing module cooperative to remove inorganic and organic pollutants from water received batchwise by the vessel.
Description
- This application is a continuation application of co-pending U.S. non-provisional application Ser. No. 11/163,160, filed Oct. 7, 2005, which is a continuation of U.S. non-provisional application Ser. No. 10/726,779, filed Dec. 3, 2003, now U.S. Pat. No. 6,953,523, both of the same inventive entity as herein, incorporated herein by reference.
- This invention is drawn to the field of water purification, more particularly, to point of use water purifiers, and more particularly, to a novel portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants.
- Systems that treat water for regional consumption such as municipal waterworks and systems that treat water for point of use consumption are the two basic types of systems by which water may be treated to remove impurities. The municipal systems, of course, afford no purification of other than “city” water, such as well water, and organic and inorganic impurities often remain in “city” water notwithstanding filtration, UV treatment, ozone treatment or treatment by any of the other water purification techniques well-known to those of skill in the art. The point of use systems for their part may be locally installed or portable. However, point of use systems installed into existing plumbing are typically line-powered, requiring line voltage and current for the treatment of water, and often involve an expense beyond the budget of many consumers for equipment acquisition, installation services and periodic maintenance. The portable point of use systems on the other hand are often cumbersome, suitcase-sized units that are difficult to use, involving multiple manual treatment steps, or do not remove both inorganic and organic impurities, and sometimes are no less expensive to acquire and maintain than their installed counterparts.
- It accordingly is the general object of the present invention to provide a novel point of use water purifier, and more particularly, to provide a portable, refillable water dispenser that itself serves batches of water purified of both organic and inorganic pollutants. As used herein, the term “organic” in the phrase “organic pollutants” refers to “living organisms” such as bacteria, and the term “inorganic” in the phrase “inorganic pollutants” refers to “non-living, organic (carbon) or inorganic compounds.”
- In general terms, the present invention contemplates a portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants that includes a portable, refillable and hand-holdable vessel for holding and pouring water having a spout and, inside the portable, refillable and hand-holdable vessel, moving water and still water processing modules cooperative to remove inorganic and organic pollutants from water received batchwise by said vessel. The module processing moving water disposed inside the vessel is adapted to receive water to be processed batchwise, and is further adapted to cause the water to be processed received batchwise to move through a flow-through filter to remove inorganic impurities and then out of said module. The module processing still water disposed inside the vessel is adapted to receive the water that flows out said module processing moving water and to contain it batchwise as a body of still water in fluid communication with said spout of said vessel, and is further adapted to provide UV radiation that is omnipresent to every region of each said body of still water contained batchwise therein with an intensity and a duration to neutralize organic impurities at every region of said body of still water contained batchwise therein. In this manner, water from which inorganic impurities have been removed and in which organic impurities have been neutralized may be dispensed through said spout of said portable, refillable and hand-holdable vessel.
- Preferably, the portable, refillable and hand-holdable vessel includes a pitcher with an open mouth and side and bottom walls that provide a basin for containing and pouring still water, a handle to one side of the pitcher, and a lid removably mounted to said open mouth of said pitcher. The module processing moving water preferably includes a bucket mounted inside said pitcher with its mouth in fluid communication with said mouth of said pitcher having an ion exchange and activated carbon flow-through filter bed that is fed by gravity action with water to be processed that is poured batchwise into said bucket all at once. The module processing still water preferably includes a single UV line radiator upstanding in, and centrally disposed within, said basin of said pitcher and a battery-powered controller carried by the pitcher that includes a control panel and user interface, preferably located on its handle, operatively coupled to the single UV line radiator.
- Preferably, the removable lid includes a fill opening, and a louvered disc valve cooperative therewith to allow water to be poured through the fill opening batchwise into the bucket of the moving water processing module while blocking direct viewing of the UV line radiator.
- Operation of the presently preferred portable, refillable and hand-holdable water dispenser serving batches of water purified of organic and inorganic pollutants is elegantly straightforward. All that is needed is to pour water to be processed batchwise into the bucket of the moving water processing module either directly, when the lid is removed, or through the fill opening, when the lid is attached to the pitcher, and to start the processing sequence by actuation of the control panel and user interface. The controller of the still water processing module waits for a first time to allow the water to be processed that has been poured batchwise into the bucket to move through the moving water processing module flow-through filter to remove inorganic impurities therefrom, then actuates the UV line radiator for a second time to neutralize organic impurities in the body of still water contained batchwise in the basin of the still water processing module, after which time it provides an indication at the control panel that a batch of water purified of organic and inorganic pollutants is ready to be dispensed through the spout of the pitcher.
- These and other objects, inventive aspects and advantageous features of the present invention will become apparent as the invention becomes better understood by referring to the following, solely exemplary, detailed description of the presently preferred embodiments thereof, and to the drawings, wherein:
-
FIG. 1 is a perspective view of a portable, refillable water dispenser serving batches of water purified of organic and inorganic impurities in accord with the present invention; -

Reference in this connection may be had to commonly assigned, co-pending United States utility patent application entitled “Filter Cartridge for a Standalone Point of Use Water Purification Device,” filed on even date herewith, incorporated herein by reference. Any suitable moving water processing module adapted to receive water to be processed batchwise and further adapted to cause the water be processed received batchwise to move through a flow-through filter to remove inorganic impurities may be employed without departing from the inventive concepts, and a flow-through filter having other than an ion exchange and activated carbon flow-through filter media such as activated carbon block media, ceramic media, or semipermeable membranes, may be employed. - The
pitcher 12 hasside walls 44 and a containedbottom wall 46 that provide a basin in fluid communication with thespout 16 for receiving, holding and pouring water. Theside walls 44 of thepitcher 12 are fashioned of a material that is transparent to ambient light and opaque to UV light, such as plastic. The capacity of the basin is at least as great as the capacity of thebucket 28. - A single UV line radiator generally designated 48 is upstanding in, and centrally positioned within, the basin of the
pitcher 12. TheUV line radiator 48 includes a two hundred fifty-four (254) nm cold cathode fluorescent lamp (CCFL) 50 and protective, UVtransparent quartz sheath 52 mounted in water-tight sealing relation to thebottom wall 46 of thepitcher 12. TheUV lamp 50 of theUV line radiator 48 is operatively connected to a controller to be described supplied by power frombatteries 52 carried in an electronics pack generally designated 54 attached to thebottom wall 46 of thepitcher 12. Theelectronics pack 54 is connected to the control panel anduser interface 20 viacable 56 that is threaded through thehandle 14 of thepitcher 12. - Water to be processed received batchwise by the
bucket 28 of the moving water processing module is received in the basin of thepitcher 12 as it flows streamwise through the flow-throughfilter 34 thereof, which, after all the water of a batch has flowed therethrough, is contained batchwise as a body of still water in the basin of thepitcher 12 in fluid communication with thespout 16. The body of still water contained batchwise in the basin completely submerges theUV line radiator 48. TheCCFL 50, actuated by the controller in response to user control input to the control panel anduser interface 20 in a manner to be described, provides UV radiation that is omnipresent to every region of the basin containing the body of still water received batchwise with an intensity and a duration to neutralize inorganic impurities at every region of the body of still water contained batchwise in the basin of thepitcher 12. The controller thereafter provides a signal indication at the control panel and user-interface 20 that a batch of water purified of organic and inorganic pollutants is ready for dispensation throughspout 16. Any still water processing module adapted to receive water from the moving water processing module and contain it batchwise as a body of still water other than the basin of thepitcher 12 and further adapted to provide UV radiation that is omnipresent to every region of the body of still water received batchwise with an intensity and a duration to neutralize inorganic impurities at every region of the body of still water contained batchwise other than the battery-powered, single UV line radiator upstanding in, and centrally disposed within, the basin of the pitcher may be employed without departing from the inventive concepts. - Referring now to
FIG. 3 , generally designated at 60 is a longitudinal view through the midsection of theremovable lid 18 of the portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants in accord with the present invention. Theflip lid 22 is pivotally mounted on anaxle 62 best seen inFIG. 4 . Theflip lid 22 covers thepour spout 16 of thepitcher 12 while allowing water contained in the basin thereof to be dispensed therethrough. Thebucket 28 includes afront wall 56 that intercepts the line of sight from thepour spout 16 to prevent direct viewing of theUV line radiator 48 in the basin of thepitcher 12 as schematically illustrated byarrow 58 inFIG. 2 . A lidseat sensing switch 64, such as a magnetic reed switch, is mounted to theremovable lid 18 to disable theUV line radiator 48 in the basin of thepitcher 12 when theremovable lid 18 is off of thepitcher 12. - A louvered disc valve generally designated 66 retained by
cap 68 onrotary bearing 70 is mounted for rotation to the underside of theremovable lid 18 adjacent the fill opening 24 thereof. Thelouvered disc valve 66 includes theactuation handle 26, and as best seen inFIG. 4 , adisc valve 72 and a louver generally designated 74, whose opening generally designated 76 is provided with a series of slanted, radially spacedfins 78. Water received through fill opening 24 of theremovable lid 18 with thelouvered disc valve 66 rotated to its fully opened position illustrated inFIG. 4 byhandle 26 flows through the louver opening 76 into thebucket 28 while theslanted fins 78 thereof block direct viewing of theUV line radiator 48 within thepitcher 12 as schematically illustrated by dashedarrow 80 inFIG. 3 . As will be appreciated, the slantedfins 78 of thelouvered disc valve 66 block direct viewing of theUV line radiator 48 inside thepitcher 12 when it is not in any of its non-fully-closed positions, not shown, which are not further described herein for the sake of brevity of exposition. Another mechanism that allows water to be processed to be received batchwise through the removable lid while blocking direct view of the UV radiator other than thelouvered disc valve 66 may be employed without departing from the inventive concepts. - Referring now to
FIG. 5 , generally designated at 90 is a block circuit diagram of the portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants in accord with the present invention.Controller 92, supplied with DC power frombattery 94, is operatively coupled toUV line radiator 96. Alid seat sensor 98 is electrically connected to thecontroller 92. A control panel anduser interface 100 is electrically connected to thecontroller 92. Thecontroller 92 may be powered by AC line power or a combination of AC and rechargeable DC without departing from the inventive concepts. - In operation, the
controller 92 in response to sequence initiation input via the control panel anduser interface 100 waits a first time to allow water to be processed received batchwise in the bucket to move through the moving water processing module and into the basin of the pitcher where it is contained as a body of still water. For an exemplary thirty-two (32) ounce capacity bucket, water received batchwise takes about takes about ten (10) minutes to drip through its flow-through filter. After the first time lapses, thecontroller 92 actuates theUV line radiator 96 to provide UV radiation that is omnipresent to every region of the body of still water contained in the basin of the still water processing module with an intensity and a second time duration to neutralize inorganic impurities at every region of the body of still water contained in the basin of the still water processing module. Different second time durations may be selected for “city” versus water from wells or other sources. For an exemplary thirty-two (32) ounce capacity basin, five (5) minutes of irradiation neutralizes organic impurities in “city” water and ten (10) minutes neutralizes organic impurities in well water. If at any time during the processing sequence (or at any other time) a signal is detected from thelid seat sensor 98, the controller disables theUV line radiator 96 and resets its water treatment sequence. Otherwise, after the second time has elapsed, thecontroller 92 provides a signal indication at the control panel anduser interface 100, such as by illuminating a light or causing an audio signal to sound, that a batch of water purified of organic and inorganic pollutants is ready to be served through the spout of the pitcher. The controller monitors the time since it was last actuated, and if a predetermined third time elapses, such as twenty-four (24) hours, since it was last actuated, it provides a signal indication at the control panel and user interface to retreat the batch of water. Many modifications of the presently disclosed invention will become apparent to those of skill in the art without departing from the inventive concepts.
