Water generating machine
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.

water from ambient air. More specifically, this invention is
directed to a device for extracting potable water from the
environment for human use.
[0003] 2. State of the Art
[0004] 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.
BRIEF SUMMARY OF THE INVENTION
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0025] This invention is a water generating machine that extracts
water from ambient air by providing a condensing surface at a
temperature below dew point. The presence of contaminates contained
in the condensed water is reduced by filtering both the ambient air
and the resulting condensate and by constructing the machine from
components that produce minimal particulate matter. Bacteriological
contamination in the condensed water is reduced by constructing the
machine from components that retard bacteria growth and by
maintaining a continuous flow of condensed water throughout the
device.

[0028] Upper thermal shield 10 is horizontally disposed within
housing 2 and extends completely between the interior sides of
front panel 3, left side panel 4, right side panel 5, and rear
panel 6 in a manner that defines the lower boundary of upper
chamber 13 and the upper boundaries of rear middle chamber 14 and
forward chamber 16. In one embodiment, upper thermal shield 10 is
joined to front panel 3, left side panel 4, and right side panel 5
with welded joints but not joined to rear panel 6. In a second
embodiment, upper thermal shield 10 is joined to front panel 3,
left side panel 4, and right side panel 5 with nut and bolt
assemblies, or equivalent, but not joined to rear panel 6. In
addition, the joints between upper thermal shield 10 and front
panel 3, left side panel 4, and right side panel 5 are sealed with
silicone caulk or similar material. In the embodiment where upper
thermal shield 10 is joined to front panel 3, left side panel 4,
and right side panel 5 with welded joints, the welded joints
prevent the exchange of air between upper chamber 13 and rear
middle chamber 14 and between upper chamber 13 and forward chamber
16. In the embodiment where upper thermal shield 10 is joined to
front panel 3, left side panel 4, and right side panel 5 with nut
and bolt assemblies, or equivalent, the seal of silicone caulk or
similar material prevents the exchange of air between upper chamber
13 and rear middle chamber 14 and between upper chamber 13 and
forward chamber 16. In either the embodiment with welded joints or
the embodiment with nut and bolt assemblies, or equivalent, the
seal of silicone caulk or similar material insulates upper chamber
13 from heat, which is typically generated by condenser coil 81A,
compressor 81, and fan motor 62 located within rear middle chamber
14 and forward chamber 16 and reduces the level of noise otherwise
produced by water generating machine 1. In addition, upper thermal
shield 10 insulates upper chamber 13 from heat located within rear
middle chamber 14 and forward chamber 16.
[0029] Upper thermal shield 10 is constructed of a first layer 17
of corrosion resistant treated metal or plastic and a second layer
18 of insulation material. In one embodiment, first layer 17 is
joined to second layer 18 using a standard adhesive. In a second
embodiment, first layer 17 is fitted to second layer 18 by
friction. In a third embodiment, second layer 18 is disposed
entirely within first layer 17 and joined using a standard adhesive
or fitted by friction. In one embodiment, first layer 17 is

greater. In a sixth embodiment, second layer 18 is a combination
open and closed celled polymer foam of relatively uniform depth of
no more than one inch having an insulation value of R5 or greater.
In subsequent embodiments, second layer 18 is any insulating
material having an insulation value of R5 or greater.
[0030] Lower thermal shield 11 is vertically disposed within
housing 2 approximately along the vertical center line of left side
panel 4 and right side panel 5 and extends between the interior
sides of bottom panel 9, left side panel 4, right side panel 5, and
the exterior side of the lower panel of environmental control
enclosure 31 in a manner that defines the lower rear boundary of
forward chamber 16 and the forward boundary of rear lower chamber
15. In one embodiment, lower thermal shield 11 is joined to bottom
panel 9, left side panel 4, right side panel 5, and the exterior
side of the lower panel of environmental control enclosure 31 with
welded joints. In a second embodiment, lower thermal shield 11 is
joined to bottom panel 9, left side panel 4, right side panel 5,
and the exterior side of the lower panel of environmental control

addition, the joints between lower thermal shield 11 and bottom
panel 9, left side panel 4, right side panel 5, and the exterior
side of the lower panel of environmental control enclosure 31 are
sealed with silicone caulk or similar material. In the embodiment
where lower thermal shield 11 is joined to bottom panel 9, left
side panel 4, right side panel 5, and the exterior side of the
lower panel of environmental control enclosure 31 with welded
joints, the welded joints prevent the exchange of air between
forward chamber 16 and rear lower chamber 15. In the embodiment
where lower thermal shield 11 is joined to bottom panel 9, left
side panel 4, right side panel 5, and the exterior side of the
lower panel of environmental control enclosure 31 with nut and bolt
assemblies, or equivalent, the seal of silicone caulk or similar
material prevents the exchange of air between forward chamber 16
and rear lower chamber 15. In either the embodiment with welded
joints or the embodiment with nut and bolt assemblies, or
equivalent, the seal of silicone caulk or similar material
insulates rear lower chamber 15 from heat predominately generated
by compressor 81 and fan motor 62 located within forward chamber
16, and condenser coil 81A located within rear middle chamber 14,
and reduces the level of noise otherwise produced by water
generating machine 1. In addition, lower thermal shield 11
insulates rear lower chamber 15 from heat located within forward
chamber 16.
[0031] Lower thermal shield 11 is constructed of a first layer 21
of corrosion resistant treated metal or plastic and a second layer
22 of insulation material. In one embodiment, first layer 21 is
joined to second layer 22 using a standard adhesive. In a second
embodiment, first layer 21 is fitted to second layer 22 by
friction. In a third embodiment, second layer 22 is disposed
entirely within first layer 21 and joined using a standard adhesive
or fitted by friction. In one embodiment, first layer 21 is
galvanized metal. In a second embodiment, first layer 21 is
stainless steel. Second layer 22 is disposed rearward of first
layer 21. In one embodiment, second layer 22 is an open celled
polymer foam of relatively uniform depth having an insulation value
of R5 or greater. In a second embodiment, second layer 22 is a
closed celled polymer foam of relatively uniform depth having an
insulation value of R5 or greater. In a third embodiment, second
layer 22 is a combination open and closed celled polymer foam of
relatively uniform depth having an insulation value of R5 or
greater. In a fourth embodiment, second layer 22 is an open celled
polymer foam of a relatively uniform depth of no more than one inch
having an insulation value of R5 or greater. In a fifth embodiment,
second layer 22 is a closed celled polymer foam of a relatively
uniform depth of no more than one inch having an insulation value
of R5 or greater. In a sixth embodiment, second layer 22 is a
combination open and closed celled polymer foam of relatively
uniform depth of no more than one inch having an insulation value
of R5 or greater. In subsequent embodiments, second layer 22 is any
insulating material having an insulation value of R5 or
greater.
[0032] The forward exterior side of the lower panel of
environmental control enclosure 31 is in communication with the
upper edge of the first layer 21 of lower thermal shield 11 and
joined with a welded joint, which prevents the exchange of air
between forward chamber 16 and rear lower chamber 15.
[0033] Front panel 3 has vents 23 and vents 23B. Left side panel 4
has vents 24 and vents 24B. Right side panel 5 has vents 25 and
vents 25B. Top support panel 8 has vents 25A. Vents 23, 24, and 25
allow air to flow between the interior space of forward chamber 16
and the exterior of housing 2. Vents 23B, 24B, and 25B allow air to
flow between the interior space of upper chamber 13 and the
exterior of housing 2. In one embodiment, vents 23, 23B, 24, 24B,
25, and 25B are louvered, which directs flowing air away from
housing 2, which forms a column of rising air distant from housing
2 and reduces the amount of flowing air that recirculates back into
housing 2. In one embodiment, the collective area of vents 24 and
25 is equal to the collective area of vents 23. In another
embodiment, the collective area of vents 24 and 25 is greater than
the collective area of vents 23.
[0034] Compressor base plate 80 is contained within the interior
space of forward chamber 16 in communication with bottom panel 9.
In one embodiment, compressor base plate 80 is secured to bottom
panel 9 with nut and bolt assemblies, or equivalent. In a second
embodiment, compressor base plate 80 is secured to tabs formed from
bottom panel 9 using retaining pins. Compressor 81 is contained
within the interior space of forward chamber 16 in communication
with compressor base plate 80. In one embodiment, compressor 81 is
secured to bottom panel 9 omitting compressor base plate 80.
Compressor 81 is sized in order to extract water from ambient air
having a temperature of between 50.degree. C. and 400.degree. C.
and a relative humidity of at least 25%. In one embodiment,
compressor 81 is controlled by electric timer 81B, which sets the
number of minutes compressor 81 is on and the number of minutes
compressor 81 is off. Any number between and including 1 and 100
may be selected for the number of minutes compressor 81 is on. In
addition, any number between and including 1 and 100 may be
selected for the number of minutes compressor 81 is off. For
example, if 5 is selected for the time compressor 81 is on and 10
is selected for the time compressor 81 is off, compressor 81 will
operate continuously for 5 minutes and then wait for 10 minutes for
an overall duty cycle of 15 minutes. In one embodiment, compressor
81 is model D40L available from Oasis, or equivalent. In another
embodiment, compressor 81 is model 5840 available from Sears, or
equivalent. Compressor 81 is secured to compressor base plate 80
with nut and bolt assemblies, or equivalent. In one embodiment, the
washers comprising one aspect of the nut and bolt assemblies, or
equivalent, are plastic. Compressor cover 82 is contained within
the interior space of forward chamber 16 in communication with
compressor 81. In one embodiment, compressor cover 82 is
constructed of fiberglass insulation wrapped in thermal resistant
plastic. In one embodiment, compressor cover 82 is secured to
compressor 81 with hook and loop fasteners. In a second embodiment,
compressor cover 82 is secured to compressor 81 with snaps. In a
third embodiment, compressor cover 82 is secured to compressor 81
with plastic ties. In subsequent embodiments, compressor cover 82
is secured to compressor 81 with any fastener suitable for
fastening fabric to metal. The placement of compressor 81 exterior
to environmental control enclosure 31 reduces the amount of
particulate matter that contacts condensation surface 72 ultimately
collecting in the liquid water or ice condensate.
[0035] Power cord 250 is in communication with power cord port 251
of housing 2 and routed to rear lower chamber 15. In one
embodiment, utility enclosure 181 incorporates a ground fault
interrupt device in the event electrical flow is disrupted, which
may occur by coming in contact with water.
[0036] Air inlet port 26 is defined by an opening in rear panel 6,
which provides fluid communication between the exterior of housing
2 and the interior space of upper chamber 13 and rear middle
chamber 14. The opening in rear panel 6 is sufficiently large to
allow access to charcoal filter housing 108, sediment filter
housing 113, and sanitization light housing 118. Primary air filter
bracket 28 is in communication with the perimeter of the opening in
rear panel 6. In one embodiment, primary air filter bracket 28 is
welded to the perimeter of the opening in rear panel 6. Primary air
filter 27 is in communication with primary air filter bracket 28.
In one embodiment, primary air filter 27 is secured to primary air
filter bracket 28 by friction. Primary air filter 27 may be removed
from primary air filter bracket 28 for inspection, cleaning, or
replacement. Primary air filter 27 is mounted so that all flowing
air passing through air inlet port 26 also passes through a first,
then second face of primary air filter 27. Primary air filter 27
removes particulates such as lint, dust, insects, pollen, and
dander from the flowing air passing through primary air filter 27.
In one embodiment, primary air filter 27 removes approximately 90%
of the particulate matter having a size equal to or larger than 1
micron from the flowing air passing through primary air filter 27.
In another embodiment, primary air filter 27 is a high efficiency
air filter capable of removing 90% of the particulate matter having
a size equal to or larger than 1 micron from the flowing air
passing through primary air filter 27. In another embodiment,
primary air filter 27 is a commercially available filter from Web
Products having Model Number 14x25. Primary air filter 27 reduces
the amount of particulate matter that contacts condensation surface
72 by collecting a portion of the particulate matter contained in
the flowing air passing through primary air filter 27.

probe 132. The end of chiller probe 132 exterior to water storage
tank 124 is in communication with heat dissipater 136, which
conducts heat away from chiller probe 132. Box fan housing 137 is
in communication with heat dissipater 136 and provides a location
for mounting box fan 138. Box fan 138 circulates air in upper
chamber 13 where it exhausts through vents 23B, 24B, 25B and 25A.
In one embodiment, chiller probe 132 is a thermo-electric cooling
device sold under the trade name Ice Probe.RTM. manufactured by
Coolworks, Inc. In a second embodiment, a cooling panel may be used
to chill water in water storage tank 124. In a third embodiment, a
refrigerant device may be used to chill water in water storage tank
124.
[0060] A first end of water recirculation tube 144 is in
communication with the perimeter of water storage tank
recirculation port 140 of water storage tank 124. In one
embodiment, first end of water recirculation tube 144 is joined to
water storage tank recirculation port 140 with a standard male pipe
adapter compression fitting. In a second embodiment, first end of
water recirculation tube 144 is joined to water storage tank
recirculation port 140 with a barbed fitting. In a third
embodiment, first end of water recirculation tube 144 is joined to
water storage tank recirculation port 140 with a barbed fitting
having a snap retainer ring attached to water recirculation tube
144. In one embodiment, water storage tank recirculation port 140
is located at an elevation between 1 and 2 inches higher than the
lowest interior point of water storage tank 124. Water
recirculation tube 144 is constructed of material suitable for use
with potable water and flexible enough to be deformed in a way that
closes the annular space inside the tube. In one embodiment, water
recirculation tube 144 is constructed of silicone tubing. 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.RTM. 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. In a fourth
embodiment, the water flow rate within water recirculation tube 144
is controlled using an inline restrictor valve. In one embodiment,
water recirculation tube 144 is secured to water storage tank
recirculation port 140 with a threaded circular fitting having an
annular space to accommodate flowing water.
[0061] Water flow rate within water recirculation tube 144 may be
controlled using a flow restrictor pinch valve. In this embodiment,
pinch valve 145 is in communication with and encloses water
recirculation tube 144. Pinch valve clamp 146 is moveably disposed
with pinch valve 145. If power to water generating machine 1 is
interrupted, actuator 147 of pinch valve 145 applies force to pinch
valve clamp 146 so that water recirculation tube 144 collapses at
the location of pinch valve clamp 146, which prevents water from
flowing through water recirculation tube 144. In this event, water
does not drain from water storage tank 124.
[0062] Water recirculation tube 144 is routed through environmental
control enclosure 31. Within environmental control enclosure 31,
water recirculation tube 144 is in communication with a portion of
condensation surface 72. The effect of water recirculation tube 144
in communication with a portion of condensation surface 72 causes
water flowing within water recirculation tube 144 to be cooled. As
a result, the cooler water inhibits the growth of bacteria in drain
port 74 and collector tray 73. In one embodiment, water
recirculation tube 144 is wrapped around evaporation coil 71 having
condensation surface 72 and remains in place as a result of
friction. In one embodiment, the surface area of water
recirculation tube 144 in contact with condensation surface 72 is
between approximately 1 and 3 square inches. A second end of water
recirculation tube 144 is disposed within environmental control
enclosure 31 and suspended above collector tray 73.
[0063] In one embodiment, water generating machine 1 has dispenser
valve 151 in communication with the perimeter of chilled water
outlet port 149 of water storage tank 124. Dispenser valve 151 is
removably secured to water storage tank 124 with a nut, threaded
tubing, or other connection suitable for immersion in potable
water. Dispenser valve 151 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 151 is accessed through dispenser valve port 151A
in front panel 3. Chilled water outlet port 149 is located at an
elevation between 1 and 8 inches higher than the lowest interior
point of water storage tank 124. In one embodiment, chilled water
outlet port 149 is located at an elevation of approximately 1 inch
higher than the lowest interior point of water storage tank 124. In
a second embodiment, chilled water outlet port 149 is located at an
elevation of approximately 8 inches higher than the lowest interior
point of water storage tank 124. In a third embodiment, dispenser
valve 151 is joined to chilled water outlet port 149 with a molded
plastic NPT fitting.
[0064] In a second embodiment, water generating machine 1 has a
dispenser valve 152 in communication with the perimeter of ambient
water outlet port 153 of water storage tank 124. Dispenser valve
152 is removably secured to water 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 in front panel 3. Ambient water outlet port 153 is
located at an elevation between 1 and 8 inches higher than the
lowest interior point of water storage tank 124. Ambient water tube
153A is disposed within the interior of water storage tank 124. A
first end of ambient water tube 153A is in communication with the
perimeter of ambient water outlet port 153 located on the interior
side of water storage tank 124. In one embodiment, a first end of
ambient water tube 153A is joined to ambient water outlet port 153
with a threaded connection. A second end of ambient water tube 153A
is disposed within the interior of water storage tank 124 and
terminates at an elevation higher than the lowest interior point of
water storage tank 124. If water storage tank 124 is fitted with
partition 127, ambient water tube 153A is routed through an opening
in partition 127 in order for ambient water tube 153A to terminate
at an elevation higher than the elevation of partition 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 ambient water outlet port 153 with a molded plastic NPT
fitting.
[0065] In a third embodiment, water generating machine 1
incorporates both dispenser valve 151 and dispenser valve 152
operating as previously described.
[0066] The combination of compressor 81, evaporation coil 71,
condenser coil 81A, and a refrigerant fluid comprises a standard
cooling apparatus, which reduces the temperature of condensation
surface 72 as compared to the ambient air drawn by rotating fan 63
and eliminates waste heat through condenser coil 81A. In an
alternate embodiment, the temperature of condensation surface 72
may be reduced by replacing refrigerant fluid with cooled water or
cooled alcohol. In a second alternate embodiment, the combination
of compressor 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 of condensation surface
72.
[0067] FIG. 10 provides a schematic view of water flow through
water generating machine 1. Liquid water or ice forms on
condensation surface 72 of evaporation coil 71. Chilled water drips
continuously from condensation surface 72 into collector tray 73 at
the bottom of environmental control enclosure 31 where it flows to
drain port 74 and into drain port connection tube 75. Under
circumstances where water condenses to form ice upon contact with
condensation surface 72, compressor 81 is cycled on and off in
order to melt the ice to liquid water to be collected in collector
tray 73. The water is deposited in pump tank 77 and remains until a
water level is reached that triggers float switch 300. Float switch
300 activates pump 104, which draws water through pump tank outlet
tube 101 into pump 104 where it is directed through pump outlet
tube 105. As water flows through pump outlet tube 105, it passes
through lower check valve 200, which prevents water from flowing in
a reverse direction, which might otherwise occur once pump 104
stops work. Water flowing through pump outlet tube 105 is directed
into upper chamber 13 where it enters charcoal filter housing 108
and passes through charcoal filter 109. Next, water flows through
charcoal filter outlet tube 110 into sediment filter housing 113
where it enters sediment filter 114. As water passes through
sediment filter 114, particulate carbon deposited in the water as a
result of passing through upstream charcoal filter 109 is trapped
in sediment filter 114. For this reason, one embodiment of water
generating machine 1 has charcoal filter 109 disposed upstream of
sediment filter 114. Water then flows through sediment filter
outlet tube 115 into sanitization light housing 118, where it is
exposed to sanitization light 120, which eliminates living bacteria
by exposing the water to ultra-violet radiation.
[0068] Next, water flows through sanitization light outlet tube 121
and passes through upper 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 in water generating machine 1. Water empties into water
storage tank 124 and remains until a high water level is reached
that triggers float switch 131. Float switch 131 deactivates water
generating machine 1, until a low water level is reached that
triggers float switch 131. Float switch 131 then activates water
generating machine. Water is directed through water recirculation
tube 144, which has a means for restricting water flow. Water is
then cooled as it is routed in proximity to condensation surface
72. Water empties into collector tray 73 where it mixes with newly
condensed water to be recycled through water generating machine 1.
In this manner, water is continuously flowing and cycled through
water generating machine 1, which helps maintain water purity and
reduces the amount of living bacteria in the water as it flows
through water generating machine 1. In addition, continuous water
flow is maintained regardless of whether compressor 81 is
operating.
[0069] Forced air flows through water generating machine 1. Upon
receiving electric power, the fan motor shaft of fan motor 62
rotates causing attached fan 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. Rotating fan 63 draws air into air inlet
port 26, through primary air filter 27, through secondary air
filter 29, and into environmental control enclosure 31 where it
contacts condensation surface 72. The air releases water onto
condensation surface 72. Next, the air flows out the outlet air
opening of environment control enclosure 31, through exit air
filter 33, and into condenser coil frame 50 where it contacts
condenser coil 81A. The air absorbs heat from condenser coil 81A.
Next, the air flows through rotating fan 63, through fan housing
64, into forward chamber 16, and through vents 23, 24 and 25. Since
the process of water condensing on condensation surface 72
generates waste heat, rotating fan 63 serves the additional
function of removing waste heat from housing 2. For this reason,
the rate with which fan 63 displaces air is maintained both to
condense water from the ambient flowing air and to cool condenser
coil 81A.
[0070] 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.
