Description
Attorney Docket No. 64944.1715
[0001] This application claims priority to and the benefit of United States Patent Application Serial No. 16/897,678, filed on June 10, 2020, which is a continuation-in-part of United States Patent Application Serial No. 16/239,161, filed on January 3, 2019, the entire disclosures of which are incorporated herein by reference.
[0002] The present disclosure relates generally to an evaporative personal air cooler with
a clip.
[0003] Evaporative personal air coolers are commonly used to cool air in a home, office,
or other hot, dry air environment. Conventional evaporative air coolers operate by drawing
ambient air into the evaporative air cooler and direct it through a water-soaked filter device.
As warm air passes through the water-soaked filters, heat from the ambient air evaporates
water trapped in the water-soaked filter device. The evaporated water cools the air as it leaves
the water-soaked filter device and exits the evaporative air cooler.
[0004] Conventional evaporative air coolers typically include a fan, a filter device, and a
water distribution system. The fan draws outside air into the evaporative air cooler, pushes it
through the filter device to produce cooler air, and then pushes the cooler air out of the
evaporative air cooler. More specifically, the water distribution system provides water to the
filter device so that the filter device becomes water soaked. The water distribution system
includes a water pump that draws water from a reservoir and distributes the water to a bottom
surface of the filter device which soaks upwards. Depending on the type of filter and the
amount of water in the reservoir, the water may travel only partially up the filters. If the filters
are not fully soaked with water, the evaporative air cooler is less effective at producing cooler
Attorney Docket No. 64944.1715
air. Filter devices typically include filters made of a paper-like material that have to be
replaced often. The filters cannot be reused or easily cleaned.
[0005] Some of the water distributed to the filter device evaporates as air flows through
the filters. The water in the reservoir depletes as the evaporative air cooler operates due to the
evaporation. Any unabsorbed water that recirculates within the evaporative air cooler returns
to the reservoir. When the reservoir is fully depleted of water but the filter device is soaked
with water, the evaporative air cooler can still produce cooler air, but it becomes less effective.
The evaporative air cooler will cease producing cooler air when the filter device is dry. Thus,
additional water must be constantly added to replace the water that has been evaporated.
[0006] It typically takes conventional evaporative air coolers a considerable period of
time to begin cooling air because the filter device must soak up water from the reservoir
before the cooling process can begin. In other words, conventional evaporative air coolers do
not instantly produce cooler air.
[0007] Furthermore, conventional evaporative air coolers are typically placed on a flat
surface, such as a table, a countertop, or a desk in order to cool people in a room. Conventional
evaporative air coolers are not configured to attach onto devices, such as an end of a shelf or
a stroller handle.
[0008] This section provides a general summary of the present disclosure and is not a
comprehensive disclosure of its full scope or all of its features, aspects, and objectives.

numbers are used in the description and drawings to identify similar elements.
[0034] The present disclosure relates generally to an evaporative personal air cooler by
which it draws in ambient air, cools the ambient air, and blows out the cooled ambient air. In
this disclosure, the evaporative personal air cooler may be referred to as an evaporative air
cooler, a portable evaporative air cooler, or any other desirable air cooler.
Attorney Docket No. 64944.1715
[0035] The evaporative air cooler 10 can include a housing 20 having a power adapter, a
water tank 40, a v-shaped shroud 44, a fan 48, a drawer 50, and a filter structure 56.
[0036] FIG. 1 illustrates an exemplary evaporative air cooler 10. The evaporative air
cooler can include the housing 20 with a top face 22, a bottom face 24, and four lateral faces,
such as a front face 26, a back face 28, and side faces 30. The housing 20 can be formed as a
cube housing, a rectangular housing, or any other desirable configuration or shape. The
housing 20 can be formed from plastic or any other desirable material.
[0037] The top face 22 can include a lid, such as a hinged lid 32. FIG. 2 illustrates the
evaporative air cooler 10 with the hinged lid 32 opened for access to the water tank 40. The
hinged lid 32 can be located along a front portion of the top face 22. The hinged lid 32 can
include a lid tab 76 positioned in the front of the hinged lid 32 or any other desirable location.
The hinged lid 32 can be opened to allow for water to fill the water tank 40. For example, a
user can pull the lid tab 76 upward to open the hinged lid 32. The hinged lid 32 can be formed
from plastic or any other desirable material. The opening to the water tank 40 can be any
desirable opening and is not limited to the hinged lid 32 described in this disclosure.
[0038] The top face 22 can also include buttons, such as a power button 34, a light
button 36, or any other desirable button. The top face 22 can also include one or more lights,
such as an indicator light 38 or any other desirable light or indicator. The indicator light 38
may be used to indicate a fan speed, a level of water located within the water tank 40, whether
filters 58 should be replaced, or any other desirable indication. For example, at a high speed,
all three indicator lights 38 can be powered ON. At a medium speed, two indicator lights 38
can be powered ON. At a low speed, one indicator light 38 can be powered ON. In one
embodiment, if the power button 34 is held down for at least three seconds, the indicator
lights 38 can all turn off. The indicator light 38 may include one or more lights. The indicator
light 38 may display a blinking light or a solid light. The indicator light 38 may display
Attorney Docket No. 64944.1715
different light colors, such as green, red, amber, or any other desirable color.
[0039] The power button 34 can be configured to activate (e.g., power ON), change the
fan speed of the fan 48, and deactivate (e.g., power OFF) the evaporative air cooler 10. For
example, when the power button 34 is first activated, the indicator light 38 (e.g., three
indicator lights 38) can turn ON, the fan 48 can turn ON (e.g., to a high speed), and an
aperture 42 positioned in the water tank 40 can allow water to flow out of the tank 40 to begin
the evaporative air cooling process. When the power button 34 is activated a second time, one
of the indicator lights 38 can turn OFF (e.g., two indicator lights 38 remain ON), the fan speed
can decrease (e.g., to a medium speed), and the aperture 42 can allow less water to flow out
of the tank 40. When the power button 34 is activated a third time, one of the indicator lights
38 can turn OFF (e.g., one indicator light 38 remain ON), the fan speed can decrease (e.g., to
a low speed), and the aperture 42 can allow less water to flow out of the tank 40. When the
power button 34 is activated a fourth time, one of the indicator lights 38 can turn OFF (e.g.,
no indicator lights 38 remain ON), the fan 48 can turn OFF, and the aperture 42 can stop the
water from flowing out of the tank 40. In other words, the power button 34 can be activated
to deactivate, or power OFF the evaporative air cooler 10. In one embodiment, when the
power button 34 is activated (e.g. pressed downward) for three or more seconds, it can turn
OFF the indicator lights 38 and the evaporative air cooler 10.
[0040] The fan 48 can be wired to the evaporative air cooler 10. The wires can be soldered
to electrically connect the fan 48 to the evaporative air cooler 10, or attached in any other
desirable way. The wires can be hidden in a wire compartment or any other desirable
compartment within the evaporative air cooler 10.
[0041] A light, such as a blue LED light, can be positioned within the water tank 40,
such as beneath the power button 34, or any other desirable area for illuminating the water
tank 40. The light can be used for ambiance, as a nightlight, or any other desirable purpose.
Attorney Docket No. 64944.1715
The light may be on by default when the evaporative air cooler 10 is powered ON. The user
can lower the brightness of the light or turn OFF the blue LED completely by pressing the
light button 36. For example, after the power button 34 is pressed, the light is on a high
brightness mode. When the user presses the light button 36 for a first time, the light can
reduce its brightness (e.g., to a low brightness mode). When the user presses the light button
for a second time, the light can turn OFF. In one embodiment, if the light button 36 is
activated for a minimum amount of time (e.g., three seconds), an illumination setting can be
selected and/or locked.
[0042] As illustrated in FIG. 2, the bottom face 24 can include feet 62 that project
outward from the bottom face 24. The feet 62 can be configured to elevate the evaporative air
cooler 10 from a surface it is placed on. The feet 62 can also be configured to prevent the
evaporative air cooler 10 from damaging the surface. For example, when sliding the
evaporative air cooler 10 across the surface, the feet 62 can prevent the scratching of the
surface. The feet 62 may be formed from rubber, plastic, grips, or any other desirable material.
The bottom face 24 can include a plurality of feet 62. The feet 62 may be formed as circular
feet 62, ovular feet 62, square feet 62, rectangular feet 62, or any other desirable shape. The
feet 62 can be positioned toward each comer of the bottom face 24, or any other desirable
location. In an alternative embodiment, the bottom face 24 does not include feet 62.
[0043] The lateral faces can include a front face 26, a back face 28, and two side faces 30.
The lateral faces can be positioned between the top face 22 and the bottom face 24 about their
outer perimeters. The lateral faces can be positioned adjacent each other. The lateral faces can
include a framed portion 64 and a face portion 66. The framed portion 64 can be positioned
about a perimeter of a lateral face, wherein the face portion 66 is positioned within the framed
portion 64. For example, the side faces 30 can include an upper portion 68, the framed
portion 64 positioned adjacent the upper portion 68 and along the side and bottom edges of
Attorney Docket No. 64944.1715
the side faces 30, and a face portion 66 positioned within the framed portion 64.
[0044] As illustrated in FIG. 3, the front face 26 can include an upper portion 68 and a
framed portion 64 positioned adjacent the upper portion 68 and along the side and bottom
edges of the top face 22. The front face 26 can also include an outlet vent 52 positioned within
the framed portion 64. The outlet vent 52 can include a plurality of vents 70, an air direction
tab 72, and a filter drawer tab 120. The plurality of vents 70 can include a fixed vent 122 and
an adjustable vent 124. For example, the fixed vent 122 may be positioned as the lowest
vent 70 on the outlet vent 52. The remainder of the plurality of vents 70 may consist of the
adjustable vent 124. Each of the plurality of vents 70 can be positioned horizontally in the
outlet vent 52. Each of the adjustable vents 124 can be movably connected to the air direction
tab 72. The air direction tab 72 can be positioned to direct air flowing from inside the
evaporative air cooler 10 through the outlet vent 52. For example, if the air direction tab 72
is positioned upward, the adjustable vents 124 may be positioned in an upward position to
direct the airflow upward. Similarly, if the air direction tab 72 is positioned downward, the
adjustable vents 124 may be positioned in a downward position to direct the airflow
downward. If the air direction tab 72 is positioned in a center position, the adjustable
vents 124 may be positioned in a substantially horizontal position, directing the air to flow
horizontally from the evaporative air cooler 10. The air direction tab 72 can direct the air to
flow at any angle between the downward and upward angles.
[0045] The face portion 66 of the front face 26, such as the outlet vent 52, can be
connected to an internal assembly 74 that is removable from the housing 20. As illustrated in
FIGS. 4 and 5, the internal assembly 74 of the evaporative air cooler 10 can include the filter
structure 56 including filters 58, the drawer 50 including a water tray 54. The internal
assembly 74 can fit tightly around the circumference of the fan 48. For example, the internal
assembly 74 can form a seal around the fan 48 to direct air out of the evaporative air cooler 10.
Attorney Docket No. 64944.1715
The internal assembly 74 can be configured to increase the force of the air as it exits the
evaporative air cooler 10 to increase the cooling effect of the evaporative air cooler 10. The
internal assembly 74 may also be configured to decrease noises produced during operation of
the evaporative air cooler 10. For example, the seal, such as an airtight seal, reduces the
amount of air escaping from the evaporative air cooler 10 and reduces air vibrating off of
other components or the walls of the evaporative air cooler 10.
[0046] The drawer 50 can be attached to the outlet vent 52. The outlet vent 52 can be
removed from the evaporative air cooler 10. For example, the fixed vent 122 can include a
filter drawer tab 120. The user can pull on the filter drawer tab 120 to remove the outlet
vent 52 from the evaporative air cooler 10. The outlet vent 52 can have one or more tabs or
any other desirable device for removing the outlet vent 52 from the evaporative air cooler 10.
An interior side of the side faces 30 can include a drawer guide 108. The drawer guide 108 is
configured to assist the user in slidably removing and inserting the drawer from and into the
housing 20.
[0047] The drawer 50 can include the water tray 54. The water tray 54 can be positioned
in the drawer 50. The water tray 54 can be formed as the bottom of the housing 20. The water
tray 54 can be angled for any liquid on the water tray 54 to flow in a direction toward the
filter structure 56. For example, the water tray 54 can be higher toward a back end 78 of the
drawer 50 than toward the front end 80 of the drawer. The water tray 54 can be configured
for cleaning. For example, when the drawer 50 is removed from the evaporative air cooler 10
and the filter structure 56 is removed from the water tray 54, the water tray 54 can be easily
accessible for cleaning. The user can wipe down and dry or otherwise clean the water tray 54.
Cleaning the water tray 54 may result in less mold or other bacteria.
[0048] The drawer 50 can be configured to support the filter structure 56. The filter
structure 56 can be removably attached to the drawer 50. The drawer 50 can have a drawer
Attorney Docket No. 64944.1715
notch 128 to secure the filter structure 56 in place. For example, the filter structure 56 can be
placed on a top surface of the water tray 54 between the outlet vent 52 and the drawer
notch 128.
[0049] As illustrated in FIGS. 6A-6C, the filter structure 56 can include a filter frame 82
and a plurality of filter holders 84 attached to opposing sides of the filter frame 82. In one
exemplary embodiment, as illustrated in FIG. 6C, the filter frame 82 can include a top
opening 86 and a bottom opening 88. The top opening 86 can be configured to allow for a
mist 118 to contact top portions 112 of the filters 58. The bottom opening 88 can be
configured to allow for the mist 118 and/or liquid, such as water, to contact bottom
portions 114 of the filters 58. For example, if liquid has collected in the water tray 54, the
liquid can contact bottom portions 114 of the filters 58. The sponge material 60 of the
filters 58 may soak up the liquid. The sponge material 60 may also soak up the mist 118 as it
contacts the filters 58. The filter holders 84 can define a plurality of holes, or filter
openings 90. Each filter opening 90 can be configured for one filter 58 to be positioned within
it. The filter holders 84 can be positioned substantially parallel to each other within the filter
structure 56. The filter holders 84 can be configured to hold the filters 58 in place. The
filters 58 can be positioned substantially parallel to each other and to opposing sides of the
filter structure 56. The filter holders 84 can be configured with space, such as air gaps 92,
between each filter holder 84 to allow for the mist 118 and/or liquid to contact thefilters 58.
The air and/or the mist 118 may also flow through the air gaps 92 and out of the evaporative
air cooler 10. The filter structure 56 can be formed from plastic, metal, or any other desirable
material.
[0050] As shown in FIGS. 4-6, the filter structure 56 can include a plurality offilters 58
mounted vertically. The filters 58 can be positioned parallel to the direction of airflow. The
filters 58 can be formed from a sponge material 60. The filters 58 can be soaked prior to use.
Attorney Docket No. 64944.1715
For example, the user can pull the filter drawer tab 120 on the outlet vent 52 to pull out the
internal assembly 74, including the drawer 50, water tray 54, and the filter structure 56. The
internal assembly 74 can slide out from within the evaporative air cooler 10. The filter
structure 56 can be removed from drawer 50. The filter structure 56 can be placed in liquid,
such as water, placed under running water, or any other desirable method to soak the filters 58.
After the filters 58 are wet, the filter structure 56 can be placed in the freezer, or any other
desirable cooling device. If the wet filters 58 are frozen, the cooling effect of the evaporative
air cooler 10 can be enhanced. When complete, the user can put the filter structure 56 on the
drawer 50 and slide the internal assembly 74 back into the evaporative air cooler 10. If the
filters 58 are pre-moistened, the initial cooling effect can increase because air travels through
the wet filters 58 when the evaporative air cooler 10 first starts running. If the filters 58 are
not presoaked, the evaporative air cooler 10 can produce cool air, but it may not be at capacity.
[0051] The filter structure 56, including the plurality of filters 58, can be constructed of
sponge material 60, plastic and sponge material 60, or any other desirable material. The filter
structure 56, together with the filters 58, can be configured for cleaning. For example, the
plastic and sponge material 60 can be cleaned using various methods, such as handwashing,
soaking, dishwasher, or any other desirable method. The filter structure 56, including the
filters 58, can be sanitized. For example, the filter structure 56, including the filters 58, can
be sanitized in a microwave or any other desirable method. The filters 58 can be handled,
washed, and used more vigorously than filters formed from paper material. The filters 58 can
be reusable, used longer while wet, re-moistened and re-dried, and have an overall longer
lifetime and usability than paper filters. The filter structure 56 can be replaced, for example,
after three to six months of use.
[0052] The evaporative air cooler 10 can also be powered ON without water in the water
tank 40 to dry out thefilters 58 and the interior of the evaporative air cooler 10. For example,
Attorney Docket No. 64944.1715
if a user plans to not use the evaporative air cooler 10 for an extended period of time, the user
can empty the water tank 40, press the power button 34 to turn the evaporative air cooler 10
ON to the high mode for a period of time, such as for four hours.
[0053] The back face 28 can include the upper portion 68 and the framed portion 64. The
back face 28 can include a power port for the power adapter. The power adapter includes a
cord with a first power adapter plug on one end that is configured to plug into the power port
and a second power adapter plug on the opposite end of the cord that is configured to plug
into an outlet, such as a wall outlet or a power strip. The power port can be located in the
upper portion 68 of the back face 28 or any other desirable location on the evaporative air
cooler 10. In another embodiment, the evaporative air cooler 10 can be powered using
batteries or another power source.
[0054] The back face 28 can also include a grate 94. The grate 94 can be positioned
within the framed portion 64. The grate 94 can include a plurality of ribs positioned
horizontally or vertically along the back face 28. As shown in FIGS. 5 and 6, the grate 94
includes both horizontal ribs 96 and vertical ribs 98 that define a plurality of grate
openings 100. The plurality of grate openings 100 are configured to allow air to flow from
outside the evaporative air cooler 10 to inside the evaporative air cooler 10. The grate 94 may
also have a cord guide for securing the cord of the power adapter in place. The cord guide
may be located along one side of the grate 94 and adjacent to the framed portion 64, or any
other desirable location. The grate 94 may have one or more cord guides tabs. Additionally,
some of the horizontal ribs 96 may be shorter to allow for the cord to be positioned flush with
the horizontal ribs 96.
[0055] As illustrated in in FIGS. 7 and 8, the fan cover assembly 102 can include the
grate 94, the fan 48, and a fan cover 46. The fan cover assembly 102 can be configured to
reduce vibration and other movement within the evaporative air cooler 10. By doing so, the
Attorney Docket No. 64944.1715
fan cover assembly 102 can reduce the noise of operation of the evaporative air cooler 10.
The fan cover assembly 102 can also efficiently direct airflow. For example, the fan cover
assembly 102 can effectively direct air outward from the evaporative air cooler 10.
[0056] For example, the fan 48 can direct airflow from the back face 28 toward the front
face 26. The fan 48 can be positioned inside the housing 20 between the grate 94 and the fan
cover 46. The fan cover 46 can be configured to further direct the airflow. For example, the
fan cover 46 can provide an optimal volume of air flow for the size and type of the evaporative
air cooler 10. The fan cover 46 can be configured to maximize the technical and electrical
specifications of the fan 48.
[0057] The user can control the speed of the fan 48. For example, the user can press the
power button 34 to toggle the fan speed between three different speeds (e.g., high, medium,
and low speeds). Changing the fan speed can change the water flow rate through the
aperture 42. The change in the water flow rate can be proportional to the change in the fan
speed. At the high speed, the water flow rate can be at a high rate. At the medium speed, the
water flow rate can be at a medium rate. At the low speed, the water flow rate can be at a low
rate.
[0058] Thus, the misting structure 104 can be configured to produce a variable volume of
the mist 118. The volume of the mist 118 produced can be based on the fan speed. For
example, as the fan speed increases, the volume of the mist 118 can increase. The increase in
the volume of the mist 118 may allow for an optimal amount of moisture to enter into the air,
which can result in a better cooling effect. As the fans speed decreases, so may the mist
volume.
[0059] For example, when the power button 34 is pressed, the evaporative air cooler 10
can turn on. The fan 48 can begin spinning, and the mist 118 can begin to spray from a misting
structure 104. The default fan speed can be the high speed when the evaporative air cooler 10
Attorney Docket No. 64944.1715
is first powered ON, or any other desirable fan speed. The user can adjust the cooling effect
of the evaporative air cooler 10, including the amount of the mist 118 and/or the airflow speed
using the power button 34. The user can adjust the airflow direction (e.g., from top to bottom)
using the air direction tab 72 on the outlet vent 52. The power button 34 can be pressed again
to turn off the evaporative air cooler 10.
[0060] As illustrated in FIG. 7, the v-shaped shroud 44 can be positioned on an underside
of the top internal panel 110 to allow liquid to transform into the mist 118. The top internal
panel 110 can be a wall between the evaporative air cooler 10 and the water tank 40, the
bottom of the water tank 40, or any other desirable structure. The v-shaped shroud 44 can be
configured to distribute the mist 118 evenly toward the filters 58. An even distribution of
liquid on the filters 58 provides an effective cooling effect for the user. The v-shaped
shroud 44 can be configured to maximize airflow to the user.
[0061] For example, the v-shaped shroud 44 can extend from the bottom of the water
tank 40 into the evaporative air cooler 10. The fan 48 used with the v-shaped shroud 44 can
turn the liquid into the mist 118 and direct the mist 118 toward the filter structure 56 and
filters 58. Some of the mist 118 may evaporate, and some of the mist 118 may travel between
the sponge material 60 and through outlet vent 52 to cool the air outside of the housing 20.
Some of the mist 118 can soak into the sponge material 60, allowing for later evaporative
cooling. Some of the mist 118 can fall into the water tray 54, where it can collect and turn
into liquid. The liquid can be absorbed into the filters 58 via capillary action, to allow for
additional evaporative cooling. The water tray 54 can be constructed with a slight angle. The
slight angle can cause excess or unabsorbed liquid to flow toward the filters 58. The excess
liquid can be absorbed by the filters 58 and wicked up, allowing for a longer cooling effect.
Also, wicking up the excess water can result in a reduction of water spills if the evaporative
air cooler 10 is moved or the drawer 50 is removed from the evaporative air cooler 10.
Attorney Docket No. 64944.1715
[0062] As illustrated in FIGS. 4 and 9, the housing 20 can include a container or a tank,
such as the water tank 40 positioned beneath the top face 22. Liquid, such as water, can be
placed into the water tank 40. For example, when the hinged lid 32 is open, liquid can be
poured into the water tank 40 using a pitcher or any other desirable means. The water tank 40
can have an opening, such as the aperture 42, to release liquid from the water tank 40 into the
evaporative air cooler 10. The aperture 42 can be positioned in the bottom of the water tank 40.
The aperture 42 can be positioned between the v-shaped shroud 44 and the front face 26.
More specifically, the aperture 42 can be positioned between the v-shaped shroud 44 and the
filter structure 56.
[0063] The evaporative air cooler 10 can use a two-stage cooling for its cooling process.
The first stage can incorporate a misting structure 104. The misting structure 104 can include
a microporous mister, such as a mister 106. The second stage can incorporate a filter
structure 56 having an evaporative sponge filter, such as filters 58 made from sponge
material 60. The combination of both stages can produce an instant cooling effect and a
prolonged cooling effect.
[0064] The mister 106 can provide the instant cooling effect. For example, when the
evaporative air cooler 10 is powered ON, the mist 118 begins spraying from a mister 106.
The power of the fan 48 can be positioned behind the mist 118 to distribute the mist 118 into
the ambient air, or air, and onto the filters 58. As the mister 106 runs for a continued period
of time, the filters 58 may become more wet (e.g., damp filters). The air that encounters the
mist 118 can feel cooler to the user due to the evaporative cooling process. As air continually
travels through the damp filter 58, the cooling effect can be prolonged. When the liquid is
depleted from the water tank 40, the mist 118 may cease but the filters 58 can remain wet for
a time period, allowing at least some evaporative cooling to continue.
[0065] The misting structure 104 can be located or partially located within the water
Attorney Docket No. 64944.1715
tank 40. For example, the mister 106 can be assembled through the aperture 42 of the water
tank 40. The misting structure 104 can be coupled to the bottom of the water tank 40, the top
internal panel 110, or any other desirable location using a misting structure coupling 126. The
misting structure coupling 126 can include a screw inserted through a screw hole, or any other
desirable attachment. The mister 106 can be positioned upside down within the top-filled
water tank 40. The mister 106 can release water downward into the interior of the evaporative
air cooler 10. Liquid can be fed directly into the mister 106. The mister 106 can distribute
mist 118 (e.g., moisture) to the sponge filter. By misting the filters 58 from an upper portion
of the evaporative air cooler 10, the mist 118 can more effectively soak into the filters 58. The
mister 106 can create an even distribution of the mist 118 to the filters 58, including to a top
portion 112 of the filters 58. Walls of the water tank 40 can have angles configured to allow
for an increased volume of liquid to reach the mister 106.
[0066] The mister 106 can be configured to restrict water flow from the aperture 42 when
the evaporative air cooler 10 is turned OFF.
[0067] The misting structure 104 can be wired to the evaporative air cooler 10. The wires
can be soldered to electrically connect the misting structure 104 to the evaporative air
cooler 10, or attached in any other desirable way. The wires can be hidden in the wire
compartment or any other desirable compartment within the evaporative air cooler 10.
[0068] The evaporative air cooler 10 can operate for a period of time. The period of time
may depend on various factors, such as the amount of water in the water tank 40, whether the
filter 58 are presoaked, whether the filters 58 were initially frozen, and a cooling mode
selected based on the fan speed. In one embodiment, the evaporative air cooler 10 can operate
for eight hours on the high mode, ten hours on the medium mode, and twelve hours on the
low mode without refilling the water tank 40.
[0069] The evaporative air cooler 10 can include additional and/or fewer components and
Attorney Docket No. 64944.1715
is not limited to those illustrated in thefigures.
[0070] In an example embodiment, the evaporative air cooler 10 includes the water
tank 40, the misting structure 104, the filter structure 56, and the fan 48. The water tank 40
can include the liquid inlet (e.g., via the hinged lid 32) and the liquid outlet (e.g., via the
aperture 42). Liquid can enter the water tank 40 through the liquid inlet and exit the water
tank through the liquid outlet. The misting structure 104 can be in liquid communication with
the water tank 40. The misting structure 104 can be configured to produce mist 118 as the
liquid flows through the liquid outlet. The filter structure 56 can include the plurality of
filters 58 positioned substantially parallel to each other and defining air gaps 92 between the
plurality of filters 58. The fan 48 can be configured to draw ambient air into the evaporative
air cooler 10 and direct the ambient air through the filter structure and out of the evaporative
air cooler 10. Thus, the ambient air can be cooled before exiting the evaporative air cooler 10.
[0071] The misting structure 104 can distribute the mist 118 into the ambient air and onto
the plurality of filters 58. The misting structure 104 can include a mister 106. The mister 106
can be positioned adjacent the water tank 40. The mister 106 can also be positioned within
the water tank 40. Liquid can flow through a top portion of the mister 106 from the water
tank 40 toward a bottom portion of the mister 106. The mister 106 can project the mist 118
from the misting structure 104 into the ambient air within the evaporative air cooler 10. The
mist 118 can cool the ambient air.
[0072] The misting structure 104 can produce a first volume of mist 118 when the fan 48
is at a first speed. The misting structure 104 can produce a second volume of mist 118 when
the fan is at a second speed. The first volume can be larger than the second volume and the
first speed can be faster than the second speed. In other words, when the fan is on high, more
mist 118 can spray from the mister 106.
Attorney Docket No. 64944.1715
[0073] The evaporative air cooler 10 can include an internal assembly 74 configured to
form a seal 116 with the fan 48. The seal 116 can cause the ambient air to exit the evaporative
air cooler 10 with a greater force than when entering the evaporative air cooler 10. The
internal assembly 74 can include at least one of the filter structure 56, and a drawer 50. The
internal assembly 74 can be removably attached to the evaporative air cooler 10. The internal
assembly 74 can comprises a drawer 50 attached to the outlet vent 52. The drawer 50 can
include a water tray 54 angled toward the outlet vent 52. The filter structure 56 can be
positioned on the water tray 54 adjacent the outlet vent 52. Any condensation or liquid in the
drawer 50 can flow toward the outlet vent 52. The plurality of filters 58 can be formed from
sponge-like material, such as sponge material 60. Thus, if the filter structure 56 is positioned
adjacent the outlet vent 52, the plurality of filters 58 can soak up the liquid as it flows toward
the outlet vent 52. If the plurality of filters 58 are at a liquid capacity, the sponge material 60
may not soak up additional liquid. The liquid in the filters 58 can be used to cool the ambient
air. When the liquid in the filters 58 cools the ambient air, the liquid may evaporate from the
filters 58. The filters 58 may not be at the liquid capacity after evaporation occurs and thus,
can soak up more liquid.
[0074] The filter structure 56 can be configured for removal from the evaporative air
cooler 10. The filter structure 56 and the plurality offilters 58 can be washable and reusable.
The plurality of filters 58 can be presoaked with liquid and inserted into the evaporative air
cooler 10. Presoaking the filters 58 can prolong the cooling of the evaporative air cooler 10.
[0075] The evaporative air cooler 10 can include a shroud, such as the v-shaped shroud 44,
adjacent to the underside of the water tank 40. The shroud can be v-shaped or any other
desirable shape.
[0076] In an example embodiment, the portable evaporative air cooler 10 for cooling
ambient air includes the misting structure 104, the filter structure 56, and the fan 48. The
Attorney Docket No. 64944.1715
misting structure 104 can be configured to evaporate liquid within the portable evaporative
air cooler 10. The filter structure 56 can include the plurality offilters 58 configured to absorb
liquid. The fan 48 can be configured to draw the ambient air into the portable evaporative air
cooler 10. The ambient air can be cooled by at least one of the mist 118 and the filter
structure 56. The fan 48 can direct the ambient air thorough the filter structure 56 and out of
the portable evaporative air cooler 10.
[0077] The plurality of filters 58 can be formed from a sponge material 60 and positioned
to define gaps, such as air gaps 92, between the plurality of filters 58. The plurality of
filters 58 can be removable from the portable evaporative air cooler 10. The plurality of
filters 58 can be soaked with liquid prior to entering the portable evaporative air cooler 10.
[0078] The filter structure 56 can be positioned in a drawer 50. The drawer 50 can be
removable from the portable evaporative air cooler 10. The portable evaporative air cooler 10
can include a front grill, such as the outlet vent 52, with the air direction tab 72 for directing
air flow and the filter drawer tab 120 for pulling the drawer 50 from the portable evaporative
air cooler 10.
[0079] In an example embodiment, the personal air cooler 10 comprises the housing 20,
the tank, such as the water tank 40, the misting structure 104, the filter structure 56, and the
v-shaped shroud 44. The housing includes a top panel (e.g., the top face 22), a bottom panel
(e.g., the bottom face 24), and side panels (e.g., the front face 26, the back face 28, and the
side faces 30) that can define an interior of the personal air cooler 10. The tank can be
positioned adjacent the top panel and at least one of the side panels and configured to receive,
store, and release liquid. The misting structure 104 can be in fluid communication with the
tank and configured to create the mist 118. The filter structure 56 can be adjacent the bottom
panel and at least one of the side panels. The v-shaped shroud 44 can be positioned underneath
the tank and configured to direct the mist 118 toward the filter structure 56.
Attorney Docket No. 64944.1715
[0080] The personal air cooler 10 can include the fan 48 positioned adjacent one of the
side panels. The personal air cooler 10 can also include a fan cover 46 adjacent the fan 48 and
configured to direct air from outside the personal air cooler 10 toward the v-shaped shroud 44.
The v-shaped shroud 44 can direct mist 118 toward a top portion of the filter structure 56 and
through the filter structure 56.
[0081] The filter structure 56 can include a plurality offilters 58 positioned substantially
parallel to each other. Each of the plurality of filters 58 can be spaced apart a specific distance,
such as 1 cm, or any other desirable distance. Thus, the plurality of filters 58 can define a
plurality of air gaps 92. The plurality of filters 58 can store the mist 118. The air can be cooled
by the mist 118. The cooled air can travels through the air gaps 92 and exit the personal air
cooler through one of the side panels. The side panel can be the side panel adjacent the filter
structure 56 and include the outlet vent 52.
[0082] FIGS. 10-19 illustrate an evaporative air cooler200 for cooling air. The
evaporative air cooler 200 can include the housing 220 with a top face 222, a bottom face 224,
and four lateral faces, such as a front face 226, a back face 228, and side faces 230. The
housing 220 may be formed in the shape of a cube, a cuboid, a half sphere, or any other
suitable shape. The housing 220 may be formed from plastic or any other desirable material.
[0083] The top face 222 can include a lid, such as a lid 232. FIGS. 12 and 13 illustrate
the evaporative air cooler 200 with the lid 232 opened for access to the tank 240. The lid 232
can be located along a front portion of the top face 222. The lid 232 can include a lid tab 276
formed as a back portion of the lid 232 or any other desirable location. The lid 232 can be
opened to allow for water to fill the tank 240. For example, a user can pull the lid tab 276
upward to open the lid 232. The lid 232 can be formed from plastic or any other desirable
material. A tank opening 244 to the tank 240 can be any desirable opening. When in a closed
position, the lid 232 can be configured to form a seal over the tank opening 244. The lid 232
Attorney Docket No. 64944.1715
and the tank opening 244 may be ovular or any other suitable shape or configuration.
[0084] The front face 226 can also include buttons, such as a power button 234 or any
other desirable button. The power button 234 can be configured to activate (e.g., power ON),
change the fan speed of the fan 248, and deactivate (e.g., power OFF) the evaporative air
cooler 200. For example, when the power button 234 is first activated, an indicator light 238
can turn ON, the fan 248 can turn ON (e.g., to a high speed), and an aperture 242 positioned
in the tank 240 can allow water to flow out of the tank 240 to begin the evaporative air cooling
process. When the power button 234 is activated a second time, the fan speed can decrease
(e.g., to a medium speed) and the aperture 242 can allow less water to flow out of the tank 240.
When the power button 234 is activated a third time the fan speed can decrease (e.g., to a low
speed) and the aperture 242 can allow less water to flow out of the tank 240. When the power
button 234 is activated a fourth time, the indicator light 238 can turn OFF (e.g., no indicator
lights 238 remain ON), the fan 248 can turn OFF, and the aperture 242 can stop the water
from flowing out of the tank 240. In other words, the power button 234 can be activated to
deactivate, or power OFF the evaporative air cooler 200. In one embodiment, when the power
button 234 is activated (e.g. depressed) for three or more seconds, it can turn OFF the
indicator light 238 and the evaporative air cooler 200.
[0085] The front face 226 can be configured to emit one or more lights, such as an
indicator light 238 or any other desirable light or indicator. The front face 226 may include a
semi-transparent section, such as a window 250. The indicator light 238 may comprise one
or more lights, such as a blue LED light, positioned within the tank 240, or any other desirable
area for illuminating the tank 240 and/or the window 250. The light can be used for ambiance,
such as for a nightlight, to indicate fan speed, to indicate that the evaporative air cooler 200
is ON, or any other desirable purpose. The light may be on by default when the evaporative
air cooler 200 is powered ON. The brightness of the indicator light 238 may be configured to
Attorney Docket No. 64944.1715
change. For example, after the power button 234 is pressed, the light may be on a high
brightness mode. When the user presses the power button 234 for a second time, the light can
reduce its brightness (e.g., to a medium brightness mode). When the user presses the light
button for a third time, the light can reduce its brightness (e.g., to a low brightness mode).
When the user presses the power button 234 for a fourth time, the indicator light 238 can turn
OFF. In one embodiment, if the power button 234 is activated for a minimum amount of time
(e.g., three seconds), an illumination setting can be selected and/or locked.
[0086] The power indicator light 236 may be used to indicate a that the evaporative air
cooler 200 is low on battery, charging, or fully charged; whether the filter 258 should be
replaced; or any other desirable indication. The power indicator light 236 may display a
blinking light or a solid light. The power indicator light 236 may display different light colors,
such as green, red, amber, or any other desirable color.
[0087] The evaporative air cooler 200 can include the housing 220. The housing 220 can
define an interior 254 of the evaporative air cooler 200. The interior 254 can be configured to
receive a filter structure 256. The filter structure 256 can include a filter frame 282. The filter
frame 282 can be formed from plastic or any other desired material. The filter structure 256
may be square, rectangular, or any other desired shape. The filter frame 282 can include a 330
bottom wall, two side walls 332, and a top wall 334. As shown in FIGS. 15 and 16A-C, the
bottom wall 330 can be coupled to a base 336. The bottom wall 330 can be configured to lock
into the base 336. The bottom wall 330 can include bottom bars 338 that define bottom
openings 340. FIG. 15 illustrates the filter structure 256 with the second filter 262 removed.
The top wall 334 can include an upper top wall 342 and a lower top wall 344. The upper top
wall 342 and the lower top wall 344 can be configured to lock together. The upper and lower
top walls 342, 344 can define top openings 346. The upper top wall 342 can comprise one or
more slits 370 between the top openings 346. The lower top wall 344 can comprise one or
Attorney Docket No. 64944.1715
more bars 368. Each of the one or more bars 368 can be positioned within one of the one or
more slits 370. The lower top wall 344 can comprise one or more tabs 372. Each of the one
or more tabs 372 can be positioned within one of the top openings 346. Each of the one or
more tabs 372 can comprise a snap 374. The snap 374 can be configured to overlap the edge
of the top opening 346. The snap 374 can be configured to secure the upper and lower top
walls 342, 344 into a locked position. The upper and lower top walls 342, 344 can couple
together via snaps or any other suitable means. The tabs 372 can be configured to angle
downward toward a center portion of the filter structure 256. The tabs 372 can be configured
to direct the mist 118, water, and the like toward the back of the filter structure 256. When
the filter structure 256 is within the interior 254 of the evaporative air cooler 200, the tabs
372 can direct the water, the mist 118, and the like toward the fan 248.
[0088] The filter structure 256 can comprise one or more filters, such as filters 258, 262.
The filter 258 can be positioned through one of the bottom openings 340 from one side of one
of the bottom bars 338 to other side of that bottom bar 338. The filter 258 can be positioned
around the top portion of one of one of the top bars 368. When the upper and lower top walls
342, 344 are in a locked position, the filter 258 and the top bars 368 are positioned within the
slits 370. The filter 258 can include this configuration for each of the bars 338, 368 to form a
zig-zag configuration of the filter 258. Each of the ends of the filter 258 can couple to one of
the side walls 332, the bottom wall 330, or any other suitable component. For example, the
side walls 332 can include hooks 364 and each of the ends of the filter 258 can include an

The grill tabs 274 may be positioned in each of the corners of the grill 252. The grill 252 can
be configured to removably couple to the front face 226 of the housing 220. Each of the grill
tabs 274 can be inserted into one of the openings 324 in the housing 220. The openings 324
can be located in the bottom face 224, the front face 226, or any other desired location in the
housing 220. When coupled to the housing 220, the grill 252 can provide a front side to the
housing 220. The grill 252 can include vents 270 (e.g., bars). The vents 270 may be
configured in a horizontal configuration, an angled configuration, any other suitable
configuration, or combination thereof. The vents 270 may be stationary. The vents 270 can
be configured to rotate. Each of the vents 270 may be aligned parallel to one another such
that the vents 270 are configured to allow for air to pass through the vents 270.
[0100] The evaporative air cooler 200 can include an angling member 210. The angling
member can be coupled to the housing 220. The angling member can include arms 352, 354
and a base 356. A first arm can be rotatably coupled to one of the side faces 230 of the
housing 220. A second arm 354 can be rotatably coupled to the opposing side face 230. In
one embodiment, the first and second arms 352, 354 couple to a center portion of the side
faces 230. The arms may be coupled to the sides via a coupling 358, such as a ratchet system
or any other desired rotatable attachment. The angling member can be configured to rotate
the housing 220. The angling member can rotate the housing 220 to position the housing 220
in an angle that a user desires. The angling member can be configured to rotate the
housing 220 in a vertical direction. The angling member 210 can be configured to rotate the
housing 220 360 degrees. The angling member 210 can maintain a position, or angle, of the
housing 220 relative to the angling member 210. For example, if a user would like the
evaporative air cooler 200 to blow cool air toward the user's face, the user may rotate the
housing 220 upward to direct the cooled air upward. Similarly, the user can rotate the housing
Attorney Docket No. 64944.1715
220 downward to direct the cooled air downward. The arms 352, 354 can be coupled to the
sides such that the housing 220 is stationary and cannot be rotated about the arms.
[0101] The first and second arms 352, 354 can protrude from either side of the base 356.
The first and second arms 352, 354 can be formed with the base 356 or coupled to the base
356. The base 356 can be formed from plastic or any other suitable material. The base 356
can be coupled to a clip 202 via a coupling 360, such as a ratchet system or any other desired
rotatable attachment. The coupling 360 can be configured to rotate housing 220 via the base
356 in either direction (e.g., to the right or to the left) 360 degrees or any other desirable
degree rotation.
[0102] The evaporative air cooler 200 can include a fastener, such as the clip 202. The
clip 202 can be a device that is rotatable or worked by a spring 380 for holding an object or
objects together or in place. For example, the clip 202 can be configured to removably couple
the evaporative air cooler 200 to the handle 206 of the stroller 204, the countertop 208, a desk,
a table, or any other suitable object. The clip 202 may include grips 382, 384 on one or more
components of the clip 202. For example, the grip 382 may be configured on a grip side 388
of the clip 202 and the grip 384 may be configured on a grip side 390 of a clip base 376. The
grips 382, 384 can be configured to more securely attach the evaporative air cooler 200 to the
object. The grips 382, 384 can be formed from rubber, plastic, or any other desired material.
The grips 382, 384 may be formed as ridges and/or a smooth surface. The smooth surface
may be configured to protect the object to which the clip 202 attaches to, such that the clip
202 does not damage (e.g., scrape, scratch, etc.) the object.
[0103] The clip 202 can be coupled to the clip base 376 via a coupling 392. The coupling
392 can comprise a rod 386 configured for insertion into rod holders 394, 396. The rod holders
394 can be coupled to or formed at the end of one of the sides of the clip. The rod holders 396
can be coupled to or formed on the grip side 390 of the base. Each of the rod holders 394, 394
Attorney Docket No. 64944.1715
can define an opening for the rod 386 to insert through. A spring 380 can define an opening
be configured for the rod 386 to insert through. The spring 380 can provide tension to the clip
202 relative to the clip base 376. In a closed position, the clip 202 may be configured such
that one end of the clip 202 (e.g., a grip end 398) extends further than the clip base 376. The
grip end 398 is configured for a user to rotate the clip 202 by exerting force on the grip end
398 to rotate the clip 202 about the coupling 392. The user can open the clip 202 for an object
to be inserted into the clip 202. When the user releases the clip 202, the tension provided by
the spring 380 couples the clip 202 to the object and secures the evaporative air cooler 200
into the desired place.
[0104] The clip 202 can include one or more support members 400. The one or more
support members 400 can be configured on opposing sides of the clip 202, along the clip 202,
or any other desired position. The one or more support members 400 can be configured to
support the evaporative air cooler 200 in an upright position when the clip 202 is in a closed
position. In other words, the one or more support members 400 support the evaporative air
cooler 200 so that the evaporative air cooler 200 does not easily tip over when it is placed on
a surface. Similarly, the clip base 376 may comprise a front face 378 configured to provide
support for the evaporative air cooler 200 when the evaporative air cooler 200 is placed on a
surface (e.g., with the clip in the closed position). The front face 378 may protect components
of the coupling 392 from being damaged. For example, the front face 378 can stop the clip
202 from being rotated too far such that the spring 380 is overextended.
[0105] The clip 202 can be coupled to the angling member 210. Specifically, the clip base
376 can be coupled to the base 356 of the angling member. 210 The clip base 376 can be
rotatably coupled to the base 356, such as to a bottom portion of the base 356. The clip base
376 may be coupled to the base 356 via the coupling 360, such as a ratchet system or any
other desired rotatable attachment. The base 356 can be configured to rotate the housing 220
Attorney Docket No. 64944.1715
about the clip base 376 in a horizontal direction. The base 356 can rotate about the clip base
376 in either direction horizontally 0-360 degrees. For example, a user can attach the
evaporative air cooler 200, via the clip 202, to the countertop 208. The user can rotate the
housing 220 of the evaporative air cooler 200 horizontally, via the base 356, toward the user.
The user can further rotate the housing 220 vertically, via the angling member 210, toward
the user. In this way, when the evaporative air cooler 200 is turned on, the cooled air can be
directed toward the user. In another embodiment, the housing 220 can be coupled to the
angling member 210 and the base 356 can be coupled to the clip base 376 such that the
housing 220 is stationary and cannot be rotated in horizontal and/or vertical directions.
[0106] As illustrated in FIGS. 13 and 14, the evaporative air cooler 200 can include a
tank 240. The tank 240 can be positioned adjacent to a top face 222 of the housing 220.
Portions of the interior of the top face 222, the front face 226, the back face 228, and the side
faces 230 of the housing 220 may form portions of the tank 240. For example, the tank 240
can be configured within the housing 220 such that the top portion of the tank 240 is an
underside of the top face 222 of the housing 220. The tank 240 can include a front side and a
bottom side coupled to the housing 220. The front side and the bottom side of the tank 240
may comprise the window 250. A light, such as the power indicator 236 can be disposed
adjacent to the bottom side of the tank 240, or any other desired location. The bottom side of
the tank 240 and the front portion of the tank 240 may comprise the window 250 and be
configured to emit light produced by the power indicator 236 throughout the tank 240. The
power indicator 236 may also be configured to emit light into the interior 254 and toward the
outside of the evaporative air cooler 200.
[0107] The tank 240 can include a liquid inlet 312 and a liquid outlet 314. The top portion
of the housing 220 can define an opening, such as liquid inlet 312. The liquid inlet 312 can
be ovular, circular, or any other desirable shape. The bottom portion of the tank 240 can define
Attorney Docket No. 64944.1715
an opening, such as the liquid outlet 314. The liquid outlet can be ovular, circular, or any other
desirable shape. The liquid outlet 314 can be positioned in the bottom of the tank 240. The
liquid outlet 314 can be positioned in a central location in the bottom of the tank 240. The
liquid outlet can be positioned adjacent a filter structure 256. The liquid outlet 314 can be
configured to receive a misting structure 304 comprising a mister 306. Liquid, such as water,
can enter the tank 240 through the liquid inlet 312 and exit the tank 240 through the liquid
outlet 312. In response to the liquid flowing through the liquid outlet 314, the mister 306 can
be configured to create, from the liquid, a mist in the interior 254 of the evaporative air cooler
200.
[0108] As illustrated in FIGS. 12 and 13, a lid 232 can be coupled to the top face 222, or
any other suitable portion of the housing 220. The lid 232 can be coupled to the top face 222
via a hinge, a cord, or any other suitable attachment. A portion of the lid 232 can be configured
to fit within the liquid inlet 312. For example, if the liquid inlet 312 is an oval shape, the lid
232 can be a slightly smaller oval shape so as to fit within the liquid inlet 312 and form a seal
316 when the lid 232 is in a closed position. The lid 232 may include an ovular seal 316 to
form a seal with the liquid inlet 312 such that liquid remains in the tank 240. The lid 232 may
be formed from plastic or any other desirable material. The seal 316 may be formed from
rubber or any other desirable material. The tank 240 can be configured to receive, store, and
release liquid. For example, when the lid 232 is open (see FIG. 13), liquid can be poured into
the tank 240 using a pitcher, a faucet, a water bottle, or any other desirablefilling means.
[0109] The mister 306 can be positioned adjacent the tank 240. The mister 306 can be
coupled to the liquid outlet 314. The mister 306 can be in fluid communication with the
tank 240. Liquid can flow through a top portion of the mister 306 from the tank 240 toward a
bottom portion of the mister 306. The mister 306 can be configured to create the mist 118
from the liquid stored in the tank 240. The mister 306 can distribute the mist 118 into the air
Attorney Docket No. 64944.1715
into the interior 254 of the evaporative air cooler 200 and onto a filter, such as the second
filter 262. The mist 118 can cool the air within the interior 254.
[0110] When the evaporative air cooler 200 is operating, the mister 306 can produce mist
118. For example, the mister 306 can be configured to create a first volume of mist 118 when
a fan 248 is at a first speed. The mister 306 can be configured to create a second volume of
mist 118 when the fan 248 is at a second speed (the aperture 242 of the misting structure 304
can allow less water to flow out of the tank 240). The mister 306 can be configured to create
a third volume of mist 118 when the fan 248 is at a third speed. Thefirst volume can be greater
than the second volume and the first speed can be faster than the second speed. In other words,
when the fan 248 is on high, a higher volume of mist 118 can spray from the mister 306.
Similarly, the first and second volumes can be greater than the third volume and the first and
second speeds can be faster than the third speed. The evaporative air cooler 200 can have a
button, such as the power button 234, for controlling the speed of the fan 248. For example,
when the power button 234 is engaged a first time, the fan 248 can operate at the first speed.
When the power button 234 is engaged for a second time, the fan 248 can operate at the
second speed. When the power button 234 is engaged for a third time, the fan 248 can operate
at the third speed. When the power button 234 is engaged for a fourth time, the fan 248 can
turn off (i.e., to end operation of the fan 248). The evaporative air cooler 200 may have any
number of speeds and is not limited to those described in this disclosure. The evaporative air
cooler 200 can have a light (e.g., the power indicator 236), such as an LED light or any other
desired light, to indicate that the evaporative air cooler 200 is operating. The power indicator
236 can be configured to indicate the speed of operation.
[0111] The evaporative air cooler 200 can include a safety interlock 320. The safety
interlock 320 can be configured to prevent operation of the evaporative air cooler 200. For
example, if at least one of the grill 252 and thefilter structure 256 is removed from the
Attorney Docket No. 64944.1715
housing 220, the safety interlock 320 can shut off operation of the evaporative air cooler 200.
The safety interlock 320 can function as a safety feature such that a user does not touch the
blades of the fan while the fan is spinning in operation.
