Definitions
- This invention relates to devices adapted for extracting water from ambient air. More specifically, this invention is directed to a device for extracting potable water from the environment for human use.
- Potable water is essential for human survival. In many environments, access to readily available sources of drinkable water is restricted if not precluded. Efforts have been made in the past to provide structures adapted to extract potable water from the environment, notable ambient air. Representative structures are those disclosed in U.S. Pat. No. 5,845,504 (LeBleu); U.S. Pat. No. 5,259,203 (Engel et al. And U.S. Pat. No. 5,669,221 (LeBleu et al). While the aforesaid structures have contributed notably to the development of solutions to the provision of potable water in hostile environments, there continues to be a need for a device which is capable of providing a supply of potable water which is free of contaminants.
- a water generating device for producing potable water from ambient air includes a housing having a first compartment, a second compartment and a third compartment.
- a water condensing surface is positioned within the first compartment.
- the device further includes a cooling apparatus which is associated with the condensing surface for cooling the condensing surface to a temperature below the dew point of the ambient air.
- a water collector is associated with the condensing surface for collecting water from the condensing surface.
- a first water storage reservoir is connected to the water collector. The first water storage reservoir is positioned in the second compartment.
- An air filter structure is positioned about the water condensing surface to enclose the water condensing surface thereby forming a filter barrier surrounding the water condensing surface. The air filter structure isolates the water condensing surface from air within the first compartment.
- the device may include an air circulating device which may be disposed between the water condensing surface and the air filter structure.
- This air circulating device may be positioned in the third compartment.
- This third compartment may be thermally isolated from the first compartment.
- Alternative constructions may further provide for the isolation of the first compartment from the second compartment.
- This isolation may be of a thermal character or alternatively, the isolation may be such as to preclude unfiltered air from passing from the first compartment to the second compartment.
- the device may include a second water storage reservoir which may be interconnected to the first water storage reservoir.
- the interconnection of this second water storage reservoir to the first water storage reservoir may include a check valve positioned intermediate the first water storage reservoir and the second water storage reservoir.
- the invention is also directed to a method of producing potable water from ambient air.
- the method includes the steps of providing a water condensing surface and isolating the water condensing surface from the environment by enclosing the surface with an air filtering apparatus.
- the method further includes the step of providing a cooling apparatus in association with the water condensing surface for cooling the water condensing surface to a temperature below the dew point of ambient air and associating the water collector with the water condensing surface for collecting water from the water condensing surface.
- the method further includes the steps of drawing ambient air through the air filtering apparatus by means of an air circulating apparatus while cooling the water condensing surface by means of the cooling apparatus and then drawing the ambient air our of the air filtering apparatus by means of the air circulating apparatus. Accordingly, air exiting the air filtering apparatus is filtered upon exiting the air filtering apparatus.
- the claimed method may, in alternative embodiments, include the step of providing a compartment about the water collector and thermally isolating the compartment from the cooling apparatus.
- the method may also include the step of providing a water collector fabricated from a silver ion anti-bacterial material.
- Alternative embodiments of the method may also include the step of filtering the water in the water collector by passing the water sequentially through a charcoal filter and subsequently through a sediment filter and a sanitation light.

Abstract
This invention is directed to a water generating apparatus for extracting water from ambient air. The apparatus provides a condensing surface which is maintained during the operation of the apparatus at a temperature which is below the dew point of the ambient air. The presence of contaminants within the extracted water are reduced by filtering the ambient air prior to its processing by the apparatus and subsequently filtering the condensate. The apparatus is constructed from components which produce minimal particulate matter. The use of such components minimizes the likelihood of those components contributing to the contamination of the water generated from the apparatus. Bacteriological contamination in the condensed water is reduced by constructing the apparatus from components that retard bacteria growth. Further diminution of bacterial growth is achieved by maintaining a continuous flow of water condensate through the apparatus.
Description
- 1. Field of the Invention
- This invention relates to devices adapted for extracting water from ambient air. More specifically, this invention is directed to a device for extracting potable water from the environment for human use.
- 2. State of the Art
- Potable water is essential for human survival. In many environments, access to readily available sources of drinkable water is restricted if not precluded. Efforts have been made in the past to provide structures adapted to extract potable water from the environment, notable ambient air. Representative structures are those disclosed in U.S. Pat. No. 5,845,504 (LeBleu); U.S. Pat. No. 5,259,203 (Engel et al. And U.S. Pat. No. 5,669,221 (LeBleu et al). While the aforesaid structures have contributed notably to the development of solutions to the provision of potable water in hostile environments, there continues to be a need for a device which is capable of providing a supply of potable water which is free of contaminants.
- A water generating device for producing potable water from ambient air according to the instant invention includes a housing having a first compartment, a second compartment and a third compartment. A water condensing surface is positioned within the first compartment. The device further includes a cooling apparatus which is associated with the condensing surface for cooling the condensing surface to a temperature below the dew point of the ambient air. A water collector is associated with the condensing surface for collecting water from the condensing surface. A first water storage reservoir is connected to the water collector. The first water storage reservoir is positioned in the second compartment. An air filter structure is positioned about the water condensing surface to enclose the water condensing surface thereby forming a filter barrier surrounding the water condensing surface. The air filter structure isolates the water condensing surface from air within the first compartment.
- In an alternative construction of the invention, the device may include an air circulating device which may be disposed between the water condensing surface and the air filter structure. This air circulating device may be positioned in the third compartment. This third compartment may be thermally isolated from the first compartment.
- Alternative constructions may further provide for the isolation of the first compartment from the second compartment. This isolation may be of a thermal character or alternatively, the isolation may be such as to preclude unfiltered air from passing from the first compartment to the second compartment.
- In yet another construction the device may include a second water storage reservoir which may be interconnected to the first water storage reservoir. The interconnection of this second water storage reservoir to the first water storage reservoir may include a check valve positioned intermediate the first water storage reservoir and the second water storage reservoir.
- The invention is also directed to a method of producing potable water from ambient air. The method includes the steps of providing a water condensing surface and isolating the water condensing surface from the environment by enclosing the surface with an air filtering apparatus. The method further includes the step of providing a cooling apparatus in association with the water condensing surface for cooling the water condensing surface to a temperature below the dew point of ambient air and associating the water collector with the water condensing surface for collecting water from the water condensing surface. The method further includes the steps of drawing ambient air through the air filtering apparatus by means of an air circulating apparatus while cooling the water condensing surface by means of the cooling apparatus and then drawing the ambient air our of the air filtering apparatus by means of the air circulating apparatus. Accordingly, air exiting the air filtering apparatus is filtered upon exiting the air filtering apparatus.
- The claimed method may, in alternative embodiments, include the step of providing a compartment about the water collector and thermally isolating the compartment from the cooling apparatus. The method may also include the step of providing a water collector fabricated from a silver ion anti-bacterial material.
- Alternative embodiments of the method may also include the step of filtering the water in the water collector by passing the water sequentially through a charcoal filter and subsequently through a sediment filter and a sanitation light.

In a second embodiment,water recirculation tube 144 is constructed of silicone tubing having a grade of “high purity.” In a third embodiment,water recirculation tube 144 is constructed of Tygon® silicone tubing. In one embodiment,water recirculation tube 144 has an internal diameter of approximately {fraction (1/16)} inch. In a second embodiment,water recirculation tube 144 provides for a water flow rate of approximately 0.041667 gal/min. In a third embodiment,water recirculation tube 144 provides for a water flow rate of approximately 0.035714 gal/min.

Pinchvalve clamp 146 is moveably disposed withpinch valve 145. If power to water generatingmachine 1 is interrupted,actuator 147 ofpinch valve 145 applies force to pinchvalve clamp 146 so thatwater recirculation tube 144 collapses at the location ofpinch valve clamp 146, which prevents water from flowing throughwater recirculation tube 144. In this event, water does not drain fromwater storage tank 124. -
Water recirculation tube 144 is routed throughenvironmental control enclosure 31. Withinenvironmental control enclosure 31,water recirculation tube 144 is in communication with a portion ofcondensation surface 72. The effect ofwater recirculation tube 144 in communication with a portion ofcondensation surface 72 causes water flowing withinwater recirculation tube 144 to be cooled. As a result, the cooler water inhibits the growth of bacteria indrain port 74 andcollector tray 73. In one embodiment,water recirculation tube 144 is wrapped aroundevaporation coil 71 havingcondensation surface 72 and remains in place as a result of friction. In one embodiment, the surface area ofwater recirculation tube 144 in contact withcondensation surface 72 is between approximately 1 and 3 square inches. A second end ofwater recirculation tube 144 is disposed withinenvironmental control enclosure 31 and suspended abovecollector tray 73. - In one embodiment,

In one embodiment, chilledwater outlet port 149 is located at an elevation of approximately 1 inch higher than the lowest interior point ofwater storage tank 124. In a second embodiment, chilledwater outlet port 149 is located at an elevation of approximately 8 inches higher than the lowest interior point ofwater storage tank 124. In a third embodiment,dispenser valve 151 is joined to chilledwater outlet port 149 with a molded plastic NPT fitting. - In a second embodiment,
water generating machine 1 has adispenser valve 152 in communication with the perimeter of ambientwater outlet port 153 ofwater storage tank 124.Dispenser valve 152 is removably secured towater storage tank 124 with a nut, threaded tubing, or other connection suitable for immersion in potable water.Dispenser valve 152 is constructed of material suitable for use with potable water and has an internal diameter sufficient to allow a water flow rate of 1 GPM at a pressure of 1 atmosphere.Dispenser valve 152 is accessed through dispenser valve port 152A infront panel 3. Ambientwater outlet port 153 is located at an elevation between 1 and 8 inches higher than the lowest interior point ofwater storage tank 124. Ambient water tube 153A is disposed within the interior ofwater storage tank 124. A first end of ambient water tube 153A is in communication with the perimeter of ambientwater outlet port 153 located on the interior side ofwater storage tank 124. In one embodiment, a first end of ambient water tube 153A is joined to ambientwater outlet port 153 with a threaded connection. A second end of ambient water tube 153A is disposed within the interior ofwater storage tank 124 and terminates at an elevation higher than the lowest interior point ofwater storage tank 124. Ifwater storage tank 124 is fitted withpartition 127, ambient water tube 153A is routed through an opening inpartition 127 in order for ambient water tube 153A to terminate at an elevation higher than the elevation ofpartition 127. In one embodiment, ambient water tube 153A is constructed of rigid nylon plastic, or equivalent. In one embodiment,dispenser valve 152 is joined to ambientwater outlet port 153 with a molded plastic NPT fitting. - In a third embodiment,
water generating machine 1 incorporates bothdispenser valve 151 anddispenser valve 152 operating as previously described. - The combination of
compressor 81,evaporation coil 71, condenser coil 81A, and a refrigerant fluid comprises a standard cooling apparatus, which reduces the temperature ofcondensation surface 72 as compared to the ambient air drawn by rotatingfan 63 and eliminates waste heat through condenser coil 81A. In an alternate embodiment, the temperature ofcondensation surface 72 may be reduced by replacing refrigerant fluid with cooled water or cooled alcohol. In a second alternate embodiment, the combination ofcompressor 81,evaporation coil 71, condenser coil 81A, and a refrigerant fluid may be replaced with a thermoelectric cooling device in order to reduce the temperature ofcondensation surface 72. - FIG. 10 provides a schematic view of water flow through
water generating machine 1. Liquid water or ice forms oncondensation surface 72 ofevaporation coil 71. Chilled water drips continuously fromcondensation surface 72 intocollector tray 73 at the bottom ofenvironmental control enclosure 31 where it flows to drainport 74 and into drainport connection tube 75. Under circumstances where water condenses to form ice upon contact withcondensation surface 72,compressor 81 is cycled on and off in order to melt the ice to liquid water to be collected incollector tray 73. The water is deposited inpump tank 77 and remains until a water level is reached that triggers floatswitch 300.Float switch 300 activatespump 104, which draws water through pumptank outlet tube 101 intopump 104 where it is directed throughpump outlet tube 105. As water flows throughpump outlet tube 105, it passes throughlower check valve 200, which prevents water from flowing in a reverse direction, which might otherwise occur once pump 104 stops work. Water flowing throughpump outlet tube 105 is directed intoupper chamber 13 where it enterscharcoal filter housing 108 and passes throughcharcoal filter 109. Next, water flows through charcoalfilter outlet tube 110 intosediment filter housing 113 where it enterssediment filter 114. As water passes throughsediment filter 114, particulate carbon deposited in the water as a result of passing throughupstream charcoal filter 109 is trapped insediment filter 114. For this reason, one embodiment ofwater generating machine 1 hascharcoal filter 109 disposed upstream ofsediment filter 114. Water then flows through sedimentfilter outlet tube 115 into sanitizationlight housing 118, where it is exposed tosanitization light 120, which eliminates living bacteria by exposing the water to ultra-violet radiation. - Next, water flows through sanitization
light outlet tube 121 and passes throughupper check valve 122, which prevents water from flowing in a reverse direction, which might otherwise occur once pump 104 stops work. By preventing water from flowing in a reverse direction,check valve 122 limits contamination to the upstream components inwater generating machine 1. Water empties intowater storage tank 124 and remains until a high water level is reached that triggers floatswitch 131.Float switch 131 deactivateswater generating machine 1, until a low water level is reached that triggers floatswitch 131.Float switch 131 then activates water generating machine. Water is directed throughwater recirculation tube 144, which has a means for restricting water flow. Water is then cooled as it is routed in proximity tocondensation surface 72. Water empties intocollector tray 73 where it mixes with newly condensed water to be recycled throughwater generating machine 1. In this manner, water is continuously flowing and cycled throughwater generating machine 1, which helps maintain water purity and reduces the amount of living bacteria in the water as it flows throughwater generating machine 1. In addition, continuous water flow is maintained regardless of whethercompressor 81 is operating. - Forced air flows through
water generating machine 1. Upon receiving electric power, the fan motor shaft offan motor 62 rotates causing attachedfan 63 to rotate. In one embodiment,fan motor 62 turns at one of two speeds. In one embodiment,fan 63 displaces air at a continuous rate of at least 185 cubic feet per minute.Fan 63 may le configured as a blade fan, cage fan, box fan, or other suitable fan. In one embodiment,fan 63 is a 9 inch air conditioner blade fan. Rotatingfan 63 draws air intoair inlet port 26, throughprimary air filter 27, throughsecondary air filter 29, and intoenvironmental control enclosure 31 where it contacts condensationsurface 72. The air releases water ontocondensation surface 72. Next, the air flows out the outlet air opening ofenvironment control enclosure 31, throughexit air filter 33, and intocondenser coil frame 50 where it contacts condenser coil 81A. The air absorbs heat from condenser coil 81A. Next, the air flows through rotatingfan 63, throughfan housing 64, intoforward chamber 16, and throughvents condensation surface 72 generates waste heat, rotatingfan 63 serves the additional function of removing waste heat fromhousing 2. For this reason, the rate with whichfan 63 displaces air is maintained both to condense water from the ambient flowing air and to cool condenser coil 81A. - While the invention has been particularly shown and described, it will be understood by those skilled in the relevant art that various changes in form and detail may be made without departing from the spirit and scope of this invention.
