Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application Ser. No. 61/589,702 filed Jan. 23, 2012, the contents
of which are hereby incorporated by reference as if set forth in
their entirety herein.
BACKGROUND
[0002] Swimming pools include pool filter systems that circulate
the pool water so as to remove debris, and to prevent algae
outbreaks and pH swings. Typically pool filter systems include a
pool pump that draws the pool water from the pool through a
drain/filter and back to the pool through a plurality of returns.
Many returns take the form of jet fittings, each having a rotatable
eyeball that directs the return flow of the pool water toward the
surface of the pool. Such an orientation creates surface agitation
to thereby force the debris to the filter, and to create an audible
sound that is desired by the pool owner.
[0003] Many pool filter systems include heaters that are configured
to heat the pool water that is being circulated through the system.
Because the jet fittings direct the return flow of the pool water
toward the surface of the pool, a large amount of heat is lost to
the atmosphere when the pool water is being heated. Such a system
has drawbacks and inefficiencies. For example, a large amount of
energy (i.e. electricity or gas) is wasted, and the amount of time
it takes to heat the pool water to the desired temperature is
unnecessarily long. Accordingly, an improved pool jet fitting that
reduces at least one of the drawbacks of the current system may be
desired.
SUMMARY
[0004] In accordance with an embodiment, a pool jet fitting can
include a housing and a redirector coupled to the housing. The
housing can include a housing body and a bore that extends through
the housing body along a first direction. The housing body can
include a coupler that is configured to mate with a coupler of a
wall mount so as to releasably couple the housing to the wall
mount. The bore is configured to receive a water flow. The
redirector is disposed within the bore of the housing. The
redirector can define an opening through which the water flow
moves. The redirector can include an actuator that is configured to
automatically move the opening from a first configuration to a
second configuration upon application of heat to the water flow by
a heater. The water flow through the opening has a first trajectory
when the opening is in the first configuration and a second
trajectory when the opening is in the second configuration. The
second trajectory is different than the first trajectory relative
to the first direction.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0039] Referring to FIGS. 1A and 1B, a pool filter system 10 is
configured to filter and/or heat water of a pool 12 in an efficient
and economical manner. The pool filter system 10 includes a
plurality of pool jet fittings 14 mounted to at least one, such as
four walls of the pool 12, a pool drain 18 mounted to a floor of
the pool 12, a pool filter 22 disposed along an upper portion of
one of the walls of the pool 12, a heater 26 that is configured to
heat the water, and a water pump 28 that is configured to receive
water from the pool filter 22 and/or the pool drain 18, and
subsequently return the water to the pool 12 through the pool jet
fittings 14. As shown in FIG. 1A, the pool filter system 10 further
includes piping 32 that operatively connects each of the pool jet
fittings 14, the pool drain 18, and the pool filter 22 to the
heater 26 and water pump 28. As shown, water flow enters the heater
26 and water pump 28 at a supply 40 and returns the water flow to
the pool 12 at a return 44. The water pump 28 is configured to
return either heated water (if the heater 26 is heating the water)
or non-heated water (if the heater 26 is not heating the
water).
[0040] The pool filter system 10 may be configured to filter and/or
heat water for any pool configuration as desired. For example, the
pool filter system 10 may filter and/or heat water through a pool
12 that is substantially square shaped as illustrated or through an
alternatively shaped pool, such as a kidney shaped pool. The pool
filter system 10 may be configured to filter and/or heat water of a
pool 12 that is configured as a swimming pool as illustrated, or
any other pool as desired, such as a hot tub or a Jacuzzi bathtub.
The pool filter system 10 may include any number of pool jet
fittings 14. For example, while the illustrated embodiment of the
pool filter system 10 includes ten pool jet fittings 14, it should
be understood that the pool filter system 10 may include a single
pool jet fitting 14 up to any number of pool jet fittings 14
depending on the size of the pool 12.
[0041] As shown in FIG. 1B, the pool jet fittings 14 may be mounted
to the wall of the pool 12, proximate to, but below the surface of
the water. As shown, the pool jet fittings 14 may be configured
such that water flow through the pool jet fittings 14 is directed
toward the pool surface to thereby agitate the pool surface. The
agitation of the pool surface not only directs any debris found on
the pool surface toward the pool filter 22, but it also creates a
sound that is often times desired. For example, such a sound may
indicate that the pool filter system 10 is operating, and/or may be
relaxing.
[0042] Now referring to FIG. 2, each pool jet fitting 14 is
configured to be releasably coupled to a respective wall mount 50
that is mounted to a wall of the pool 12. The pool jet fitting 14
and the wall mount 50 together define a pool jet fitting assembly
54. As shown in FIG. 2, the assembly 54 defines a distal end D, a
proximal end P, and a center axis C that extends along a
longitudinal direction L between the proximal end P and the distal
end D. The pool jet fitting 14 is configured to automatically
adjust between an agitation or first position when the water flow
is not being heated by the heater 26, and a heating or second
position when the water flow is being heated by the heater 26. The
automatically adjusting pool jet fitting 14 automatically adjusts
the trajectory of the water flow through the pool jet fitting 14
when the water flow is being heated by the heater 26 so as to
reduce heat loss to the atmosphere. That is, the pool jet fitting
14 is configured to automatically redirect the water flow into the
pool instead of toward the surface of the pool so that the amount
of heat lost to the atmosphere is reduced when the water flow is
being heated by the heater 26.
[0043] As shown in FIG. 2, each pool jet fitting 14 includes a
housing 60 that is configured to couple to the wall mount 50, a
redirector 62 positioned within the housing 60, and a cap 63 that
is coupled to the distal end of the housing 60 to thereby retain
the redirector 62 within the housing 60. The redirector 62 is
configured to automatically redirect the trajectory of the water
flow through the pool jet fitting 14 from a first trajectory to a
second trajectory upon the application of heat to the water flow by
the heater 26.
[0044] Referring to FIGS. 3A-3C, the wall mount 50 may be a
pre-existing or standard wall mount already attached to the wall of
the pool 12. Therefore, the pool jet fitting 14 may be sized and
configured to be coupled to a wall mount 50 of a pre-existing pool.
It should be understood, however, that the wall mount 50 may be a
standard wall mount to be used in a newly built pool or a new wall
mount that is different than the current standard wall mounts. As
shown in FIG. 3A, the wall mount 50 includes a wall mount body 80
that defines a tubular portion 84 and a shoulder 88 that extends
radially outward from a distal end of the tubular portion 84. The
wall mount body 80 further defines a bore 92 that extends through
the wall mount body 80 from the proximal end to the distal end of
the body 80. The bore 92 is configured to receive the water flow
from the water pump 28.
[0045] The tubular portion 84 is configured to be glued or
otherwise affixed within a bore defined by the wall of the pool 12.
As shown in FIG. 3C, the tubular portion 84 has a length D.sub.1
that is defined between the proximal end of the tubular portion 84
and an inner surface of the shoulder 88. The length D.sub.1 of the
tubular portion 84 is between about 1.25 inches and about 1.75
inches, and typically is about 1.5 inches for standard wall mounts
50. When the wall mount 50 is affixed to the pool wall, the tubular
portion 84 will extend into the wall until an inner surface of the
shoulder 88 abuts the surface of the pool wall.
[0046] As shown in FIGS. 3A and 3C, the wall mount 50 further
includes a coupler, such as internal threads 96 that extend out
from an inner surface 100 of the bore 92 of the wall mount body 80
proximate to a distal end of the wall mount 50. The threads 96 are
configured to engage threads of the housing 60 so as to releasably
couple the housing 60 to the wall mount 50. It should be
understood, however, that the wall mount 50 is not limited to
threads 96, and that the wall mount 50 may include any coupler that
is capable of releasably coupling the housing 60 to the wall mount
50.
[0047] As shown in FIGS. 3A and 3B, the wall mount 50 further
includes a lip 104 that extends out from the inner surface 100 of
the bore 92 proximal to the threads 96. The lip 104 is configured
to act as a stop and prevent over insertion of the housing 60 when
the housing 60 is inserted into the bore 92 and coupled to the wall
mount 50.
[0048] Referring to FIGS. 4A-4C, the housing 60 includes a tubular
body 120 having a distal end 121, a proximal end 122 spaced from
the distal end along a first direction (i.e. the longitudinal
direction L), and a bore 124 that extends through the body 120 from
the distal end 121 to the proximal end 122 along the first
direction. The tubular body 120 is configured to be releasably
coupled to the wall mount 50 such that when coupled, the bore 124
of the housing 60 is in line with or otherwise coaxial with the
bore 92 of the wall mount 50. Therefore, like the wall mount 50,
the housing 60 is configured to receive the water flow from the
water pump 28. As shown, the tubular body 120 defines a first
coupler, such as external threads 128 that extend out from an
external surface 132 of the body 120 proximate to the proximal end
122 of the housing 60. The threads 128 are configured to engage the
internal threads 96 of the wall mount 50 to thereby releasably
couple the housing 60 to the wall mount 50. In particular the
housing 60 is threaded into the bore 92 of the wall mount 50 until
the proximal end of the housing 60 abuts the lip 104 within the
bore 92. At this point, the housing 60 will be fully coupled to the
wall mount 50.
[0049] The tubular body 120 further defines a second coupler, such
as external threads 140 that extend out from the external surface
132 of the body 120 proximate to the distal end 121 of the housing
60. The threads 140 are configured to engage threads of the cap 63
so as to releasably affix the cap 63 to the distal end of the
housing 60. It should be appreciated, however, that the housing 60
is not limited to threads 128 and 140, and that the housing 60 may
include any coupler that is capable of releasably coupling the
housing 60 to the wall mount 50 and the cap 63 to the housing
60.
[0050] As shown in FIGS. 4A and 4B, the housing 60 further includes
a lip 144 that extends out from an inner surface 142 of the bore
124 proximate to the proximal end of the housing 60. The lip 144 is
configured to act as a stop and prevent over insertion of the
redirector 62 when the redirector 62 is placed within the bore 124
of the housing 60. Moreover, when the cap 63 is coupled to the
external threads 140 of the housing 60 the redirector 62 will be
locked or otherwise held within the bore 124 of the housing 60
between the cap 63 and the lip 144.
[0051] Now in reference to FIGS. 5A-5G, the redirector 62 is
configured to be disposed within the bore 124 of the housing 60.
The redirector 62 defines an opening 148 through which the water
flow received by the housing 60 moves. As shown, the redirector 62
includes an insert 150, a valve 154 that defines the opening 148
and is positioned within the insert 150, and an actuator 158 that
is configured to automatically move the opening 148 from a first
configuration to a second configuration upon application of heat to
the water flow by the heater 26. The water flow through the opening
148 can have a first trajectory when the opening 148 is in the
first configuration, and the water flow through the opening 148 can
have a second trajectory when the opening 148 is in the second
configuration. The second trajectory can be different than the
first trajectory relative to the first direction. For example, the
first trajectory can be toward the surface of the pool and the
second trajectory can be away from the surface of the pool. It
should be appreciated, however, that the first and second
trajectories can be along directions other than those described.
For example, the second trajectory can be parallel to the surface
of the pool rather than away from the surface of the pool.
[0052] As shown in FIGS. 5A-5G, the insert 150 can be rotatable
relative to the housing 60. As shown, the insert 150 can include an
insert body 250 that defines a passageway 254 that extends
longitudinally through the body 250 along a second direction. The
second direction can be parallel to the first direction or angular
offset relative to the first direction. The direction in which the
second direction extends depends on the orientation of the insert
150 within the housing 60. The insert body 250 is substantially
cylindrical and defines an outer surface 257 that curves radially
inward as the body 250 extends distally.
[0053] The insert 64 is configured to be disposed within the bore
124 of the housing 60. The insert 64 is configured to be disposed
within the bore 124 of the housing 60 such that the insert 64 is
capable of rotating relative to the housing 60. Therefore, when the
pool jet fitting 14 is coupled to the wall mount 50, the insert 64
can be rotated so as to position the insert such that the
passageway 254 of the insert 64 is directed or otherwise extending
towards the pool surface. Water flow from the water pump 28 will
then be directed to the surface of the pool to create the desired
agitation. It should be appreciated, however, that the insert 64
can be configured to not be capable of rotating relative to the
housing 60, as desired.
[0054] The passageway 254 of the insert 64 may be sized to receive
the valve 154 such that the valve 154 rotates along with the
rotatable insert 64, when the rotatable insert 64 is rotated.
Therefore, the opening 148 of the valve 154 can face the surface of
the pool 12 when the insert 64 is rotated to face the surface of
the pool 12. It should be appreciated, that while the opening 148
of the valve 154 is aligned along the second direction, that the
valve 154 can be positioned within the insert 64 such that the
opening 148 of the valve 154 is angularly offset with respect to
the second direction.
[0055] As shown in FIGS. 5F and 5G, the valve 154 includes a valve
body 264, and a plurality of flexible members 268 that extend
distally from the valve body 264. As shown in FIGS. 5F-5G, each
member 268 extends from the body 264 such that the members 268
together define a substantially cone shaped structure. That is, as
the members 268 extend distally they extend toward the center axis
of the valve 154. As shown, the valve 154 can further include a
plurality of extendable sections 270 that each extend between and
are coupled to a respect pair of adjacent members 268. The valve
body 264, flexible members 268, and extendable sections 270 can be
integrally formed as a monolithic structure or can be individual
components made separately and subsequently assembled.
[0056] Each member 268 is configured to flex and includes a flexing
portion 288 that extends distally from the valve body 264. Each
member 268 is substantially triangular in shape and defines a
distal end 292 and a proximal end 296 that is wider than the distal
end 292. As shown, together the distal ends 292 of the members 268
define the opening 148 which in the illustrated embodiment is star
shaped. The valve 154 including the body 264, the members 268, and
the extendable sections 270 may be made of any material as desired.
For example, the valve 154 including the body 264, the members 268,
and the extendable sections 270 may be made of a plastic
material.
[0057] Each member 268 is configured to flex, such that when the
flow rate of the water from the water pump 28 increases, the
members 268 flex outwardly to thereby increase the dimension of the
adjustable opening 148. That is, each flexing portion 288 pivots
about a respective hinge 300 so as to widen the adjustable opening
148 from a first or initial dimension, to a second or expanded
dimension. Because the valve 154 includes an adjustable opening
148, the valve 154 is configured to maintain a predetermined
outflow velocity of water through the pool jet fitting 14 as the
flow rate of the water flow from the water pump 28 changes. The
predetermined outflow velocity may correspond to a range of
velocities having a minimum velocity at which the water flow is
visible or otherwise agitates the surface of the pool.
[0058] At least one such as two or three of the members 268 are
also configured to flex inward to thereby redirect the water flow
through the opening 148 from the first trajectory to the second
trajectory. For example, when the water flow is being heated by the
heater 26, the at least one member 268 can flex inwardly toward the
center of the opening 148 to thereby redirect the water away from
the surface of the pool. The trajectory of the water flow through
the opening 148 when the water flow is being heated by the heater
26 can depend on the initial position of the valve 154 and insert
64 and the amount the at least one member 268 is flexed.
[0059] As shown in FIGS. 5A-5G, and 6A-6B, the actuator 158 is in
communication with the at least one flexible member 268 and is
configured to automatically apply a force to the at least one
flexible member 268 when the water flow is being heated by the
heater 26 to thereby redirect the water flow from a first
trajectory 304 relative to the first direction to a second
trajectory 308 relative to the first direction that is different
than the first trajectory 304 as the water flow moves through the
opening 148. The actuator 158 can also be configured to
automatically remove the force that is applied to the at least one
flexible member 268 when the water flow is no longer being heated
by the heater 26 to thereby redirect the water flow from the second
trajectory 308 back to or at least substantially back to the first
trajectory 304. Therefore it can be said that the actuator 158 is
configured to automatically move the opening 148 from a first
configuration to a second configuration upon application of heat to
the water flow by the heater 26. As shown in FIG. 6A, the first
trajectory 304 can be at a first angle relative to the first
direction, and as shown in FIG. 6B the second trajectory 308 can be
at a second angle relative to the first direction. The first angle
can be greater than the second angle. The first angle can be great
enough such that the first trajectory 304 is substantially toward
the surface of the pool so as to provide adequate agitation to the
surface of the pool. The second angle can be such that the second
trajectory 308 is away from the surface of the pool. It should be
appreciated, however, that the second trajectory 308 can be toward
the surface of the pool but at an angle relative to the first
direction that is less than the first angle. Moreover it should be
appreciated that the second trajectory can be parallel to the
surface of the pool and substantially along the first
direction.
[0060] As shown in FIGS. 5A-5G and 6A-6B, the actuator 158 can
include a thermostatic element 312 and at least one such as two
tethers 316 that couple the thermostatic element 312 to the at
least one flexible member 268. The actuator 158 can further include
a panel 318 coupled to the at least one flexible member 268 and the
tethers 316 can be coupled to the panel 318 so as to be configured
to apply a downward force to the at least one flexible member 268
to thereby move the opening 148 from the first trajectory 304 to
the second trajectory 308. The panel 318 can be coupled to an outer
surface of the at least one flexible member 268 or to an inner
surface of the at least one flexible member 268. It should be
appreciated, however, that the panel 318 can be indirectly coupled
to the at least one flexible member 268 such that a structure is
between the panel 318 and the at least one flexible member 268 or
the panel 318 can be coupled to the at least one flexible member
268 such that the panel 318 is floating or otherwise resting
against the at least one flexible member 268.
[0061] The thermostatic element 312 includes an actuator housing
320 and a moveable rod 324 that is moveable relative to the
actuator housing 320 between a first position in which the tethers
316 are slack, and a second position in which the tethers 316 apply
the force to the at least one flexible member 268. The actuator
housing 320 can include a proximal cylindrical body portion 330, a
distal hollow body portion 334, and a shoulder 338 between the
proximal body portion 330 and the distal body portion 334. The
distal body portion 334 can define a cavity that contains an
expandable material such as wax. The moveable rod 324 extends into
the cavity of the distal body portion 334 such that when the water
flow is heated by the heater 26 the wax within the cavity melts and
expands to thereby move the rod 324 to the second position. When
the water flow is no longer being heated by the heater 26, the wax
solidifies and contracts thereby providing space for the rod 324 to
return to the first position. It should be appreciated, however,
that the thermostatic element 312 can include other configurations.
For example, the thermostatic element 312 can include expandable
materials other than wax.
[0062] As shown in FIGS. 5A-5G and 6A-6B, the actuator 158 further
includes a holder 340 that is configured to couple the thermostatic
element 312 to the valve 154 such that the thermostatic element 312
is elongate along the second direction and the rod 324 moves along
the second direction. The holder 340 can include a cylindrical or
ringed member 344 that mates with a groove defined by the valve
body so as to couple to the valve body. The holder 340 further
includes a distal holder portion 348 that is configured to mate
with a distal end of the moveable rod 324, and a proximal holder
portion 352 that is slidably coupled to the proximal body portion
330 of the actuator housing 320. The holder 340 includes at least
one such as four spokes 354 that couple the distal holder portion
348 to the ringed member 344, and at least one such as four spokes
356 that couple the proximal holder portion 352 to the ringed
member 344.
[0063] The proximal holder portion 352 defines a channel 360 that
extends along the second direction and receives the proximal body
portion 330 of the actuator housing 320 such that the proximal
holder portion 352 is translatable along an outer surface of the
proximal body portion 330 along the second direction. The proximal
holder portion 352 at least partially holds the thermostatic
element 312 at least partially within the valve 154. The channel
360 and the proximal body portion 330 are illustrated as being
cylindrical though it should be appreciated, that the channel 360
and the proximal body portion 330 can have other configurations so
long as the proximal holder portion 352 is translatable along the
proximal body portion 330.
[0064] The distal holder portion 348 defines a recess 364 that
receives the distal end of the rod 324. As the rod 324 moves to the
second position the rod 324 engages the recess 364 and pushes the
thermostatic element 312 proximally relative to the holder 340 to
thereby remove the slack from and subsequently apply tension to the
tethers 316.
[0065] As shown, the actuator 158 further includes a biasing member
370 such as a spring that is disposed about the proximal body
portion 330 between the proximal holder portion 352 and the
shoulder 338. The biasing member 370 is configured to apply a
biasing force against the shoulder 338 of the thermostatic element
312. While the biasing member 370 is illustrated as a spring it
should be appreciated, that the biasing member can have other
configurations. For example, the biasing member 370 can be a rubber
insert.
[0066] In operation, the redirector 62 is originally positioned
within the bore of the housing 60 such that the first trajectory
304 of the water flow through the opening 148 is toward the pool
surface. When the water flow is heated by the heater 26, the wax
within the thermostatic element 312 melts and forces the rod 324 to
the second position. As the rod 324 moves to the second position
the distal end of the rod 324 engages and pushes against the recess
364 of the distal holder portion 334 to thereby push the
thermostatic element 312 proximally relative to the holder 340 such
that the tethers 316 are pulled proximally and the panel 318
applies a downward force to the at least one flexible member 268.
The force against the at least one flexible member 268 will move
the opening 148 to the second configuration and redirect the water
flow through the opening 148 to the second trajectory 308 as shown
in FIG. 6B. When the water flow is no longer being heated by the
heater 26, the wax within the thermostatic element 312 solidifies
and allows the rod 324 to move back to the first position as shown
in FIG. 6A. When the rod 324 moves back to the first position, the
biasing member 370 biases the thermostatic element 312 distally
relative to the holder 340 such that the tethers 316 are returned
to their slacked position and the downward force is removed from
the at least one flexible member 268. With the force removed, the
water flow through the opening 148 will return to the first
trajectory 304. This process can occur each time the water flow is
being heated by the heater 26 for a period of time. In this way the
redirector 62 automatically moves the water flow through the
opening 148 between the first trajectory 304 and the second
trajectory 308.
[0067] It should be appreciated that the redirector 62 can include
actuators that have other configurations. For example, in another
embodiment and in reference to FIG. 7, the redirector 62 can
include an actuator 380 that includes a panel 384 that is pivotally
coupled to either the valve 154 or the insert 150 at a pivot 388
that defines a pivot axis that extends perpendicular to the first
direction. The actuator 380 can further include a thermostatic
element 392 that is configured to move the panel 384 about the
pivot 388 and apply the downward force to the at least one flexible
member 268. The panel 384 can include a distal panel portion 396
that extends distal to the pivot 388 and is configured engage the
at least one flexible member 268. The panel 384 can further include
a proximal panel portion 400 that extends proximal to the pivot 388
and is configured to be contacted by the thermostatic element
392.
[0068] The thermostatic element 392 is substantially similar to and
functions substantially similar to the thermostatic element 312.
Therefore like the thermostatic element 312, the thermostatic
element 392 includes an actuator housing 404 and a rod 408 moveable
relative to the actuator housing 404 between a first position and a
second position. When the water flow is being heated by the heater
26 the rod 408 moves to the second position and contacts the
proximal panel portion 400 to thereby cause the panel 384 to rotate
or otherwise pivot about the pivot 388. The distal panel portion
396 will then contact an outer surface of the at least one flexible
member 268 and to thereby apply the downward force to the at least
one flexible member 268 and redirect the water flow through the
opening to the second trajectory. When the water flow is no longer
being heated by the heater 26 the rod 408 moves back to the first
position to thereby remove the force from the at least one flexible
member 268 that is applied by the panel 384 and redirect the water
flow through the opening back to the first trajectory. Therefore it
can be said that the actuator 380 is configured to automatically
move the opening 148 from a first configuration to a second
configuration upon application of heat to the water flow by the
heater 26. The actuator 380 can perform this process each time the
heater 26 heats the water flow for a period of time.
[0069] Now in reference to FIGS. 8A and 8B, it should be
appreciated that the redirector can have other configurations to
move the opening from the first configuration to the second
configuration. For example, the redirector can be configured change
the trajectory of the water flow by rotating an insert rather than
manipulating flexible members on a valve. For example, in another
embodiment and in reference to FIGS. 8A and 8B, a redirector 420
can include an insert 424 that is rotatably coupled to the housing
60 within the bore of the housing 60 at a pivot 428. The pivot 428
defines a pivot axis that is substantially perpendicular to the
first direction. The pivot 428 can be a pair of pins or any other
structure that is capable of rotatably coupling the insert 424 to
the housing 60. As shown, the insert 424 is rotatable relative to
the housing 60 about the pivot 428.
[0070] The insert 424 can be substantially identical to the insert
64 shown in FIG. 5A. As shown, the insert 424 includes an insert
body 450 that defines a passageway 454 that extends longitudinally
through the body 450 along a second direction. The distal end of
the passageway 454 can define an opening 456 through which the
water flow exits. The second direction can be parallel to the first
direction or angular offset relative to the first direction. The
direction in which the second direction extends depends on the
orientation of the insert 424 within the housing 60. Moreover,
because the redirector 420 changes the trajectory of the water flow
by rotating the insert 424, the second direction will change during
operation.
[0071] The redirector 420 further includes an actuator 458 that is
configured to automatically move the rotatable insert 424 between a
first position when the water flow is not being heated, and a
second position when the water flow is being heated. As shown, the
water flow through the opening 456 has a first trajectory relative
to the first direction when the insert 424 is in the first
position, and the water flow through the opening 456 has a second
trajectory relative to the first direction that is different than
the first trajectory when the insert 424 is in the second position.
Therefore it can be said that the actuator 458 is configured to
automatically move the opening 456 from a first configuration to a
second configuration upon application of heat to the water flow by
the heater 26.
[0072] As shown in FIGS. 8A and 8B, the actuator 458 is in
communication with the insert 424 and is configured to
automatically apply a force to the insert 424 when the water flow
is being heated by the heater 26 to thereby move the opening 456 to
the second configuration and redirect the water flow from a first
trajectory relative to the first direction to a second trajectory
relative to the first direction that is different than the first
trajectory as the water flow moves through the opening 456. As
shown in FIGS. 8A and 8B, the actuator 458 can include a
thermostatic element 472 that is substantially similar to and
functions substantially similar to the thermostatic element 312.
Therefore like the thermostatic element 312, the thermostatic
element 472 includes an actuator housing 474 and a rod 478 moveable
relative to the actuator housing 474 between a first position and a
second position. When the water flow is being heated by the heater
26 the rod 478 moves to the second position thereby causing the
insert 424 to rotate about the pivot 428 and move to the second
position. When in the second position, the water flow moves through
the opening 456 along the second trajectory. When the water flow is
no longer being heated by the heater 26, the rod 478 moves back to
the first position thereby causing the insert 424 to rotate about
the pivot 428 and move back to the first position. When in the
first position, the water flow moves through the opening 456 along
the first trajectory and toward the surface of the pool. The
actuator 458 can perform this process each time the heater 26 heats
the water flow for a period of time.
[0073] In another embodiment and in reference to FIGS. 8C and 8D,
the redirector 420 can include an insert that is configured as the
valve 154. As shown, the valve 154 can be rotatably coupled to the
housing 60 within the bore of the housing 60 at a pivot 480. The
pivot 480 can define a pivot axis that is substantially
perpendicular to the first direction. As with the insert 424, the
actuator 458 can move the valve 154 between a first position when
the water flow is not being heated by the heater 26 and a second
position when the water flow is being heated by the heater 26. When
in the first position, the water flow moves through the opening 148
defined by the valve 154 along the first trajectory and toward the
surface of the pool. When in the second position, the water flow
moves through the opening 148 along the second trajectory.
Therefore it can be said that the actuator 458 is configured to
automatically move the opening 148 from a first configuration to a
second configuration upon application of heat to the water flow by
the heater 26. This process can be performed each time the heater
26 heats the water flow for a period of time.
[0074] Now in reference to FIGS. 9A and 9D, the redirector can be
configured change the trajectory of the water flow by rotating an
insert having a valve fixed within the passageway of the insert. As
shown in FIGS. 9A-9D, a redirector 420a can be similar to the
redirector 420 shown in FIGS. 8A and 8B and can include like
structure unless otherwise described. As shown in FIGS. 9A and 9B,
the redirector 420a can include an insert 424a that is rotatably
coupled to the housing 60 within the bore of the housing 60 at a
pivot that defines a pivot axis 428a. The pivot axis is
substantially perpendicular to the first direction. The pivot can
be a pair of pins or any other structure that is capable of
rotatably coupling the insert 424a to the housing 60. As shown, the
insert 424a is rotatable relative to the housing 60 about the pivot
axis 428a.
[0075] The insert 424a can be substantially identical to the insert
64 shown in FIG. 5A and can include a valve 154 fixed to the insert
424a. As shown, the insert 424a includes an insert body 450a that
defines a passageway 454a that extends longitudinally through the
body 450a along a second direction. The redirector 420a can include
a valve such as valve 154 fixed to the insert 424a within the
passageway 454a. The distal end of the valve 154 defines an opening
148 through which the water flow exits. The second direction can be
parallel to the first direction or angular offset relative to the
first direction. The direction in which the second direction
extends depends on the orientation of the insert 424a within the
housing 60. Moreover, because the redirector 420a changes the
trajectory of the water flow by rotating the insert 424a, the
second direction will change during operation.
[0076] The insert 424a can further include a first plate 456a that
extends from the insert body 450a and into the passageway 454a and
a second plate 456b that extends from the insert body 450a and into
the passageway 454a. The body 450a, first plate 456a, and second
plate 456b can be molded as a monolithic structure or the first and
second plates 456a and 456b can be separate component(s) that are
attached to the body 450a. The first plate 456a can be positioned
on a first side of the pivot axis and the second plate 456b can be
positioned on a second side of the pivot axis that is opposite the
first side. As shown in FIG. 9B, the first and second plates can be
opposed to each other along a direction that is perpendicular to
the first and second directions.
[0077] The redirector 420a further includes an actuator 458a that
is configured to automatically move the rotatable insert 424a
between a first position when the water flow is not being heated,
and a second position when the water flow is being heated. As shown
in FIGS. 9C and 9D, the water flow through the opening 148 has a
first trajectory relative to the first direction when the insert
424a is in the first position, and the water flow through the
opening 148 has a second trajectory relative to the first direction
that is different than the first trajectory when the insert 424a is
in the second position. Therefore it can be said that the actuator
458a is configured to automatically move the opening 148 from a
first configuration to a second configuration upon application of
heat to the water flow by the heater 26.
[0078] As shown in FIG. 9B, the actuator 458a can be positioned on
the first side of the pivot axis and in communication with the
insert 424a and in particular with the first plate 456a. The
actuator 458a is configured to automatically apply a force to the
insert 424a, and in particular to the first plate 456a when the
water flow is being heated by the heater 26 to thereby move the
opening 148 to the second configuration and redirect the water flow
from a first trajectory relative to the first direction to a second
trajectory relative to the first direction that is different than
the first trajectory as the water flow moves through the opening
148 as shown in FIG. 9D. As shown in FIGS. 9C and 9D, the actuator
458a can include a thermostatic element 472a that is substantially
similar to and functions substantially similar to the thermostatic
element 312. Therefore like the thermostatic element 312, the
thermostatic element 472a includes an actuator housing 474a and a
rod 478a moveable relative to the actuator housing 474a between a
first position and a second position. When the water flow is being
heated by the heater 26 the rod 478a moves to the second position
thereby causing the insert 424a to rotate about the pivot 428a and
move to the second position. When in the second position, the water
flow moves through the opening 148 along the second trajectory.
When the water flow is no longer being heated by the heater 26, the
rod 478a moves back to the first position thereby allowing the
insert 424a to rotate about the pivot 428a and move back to the
first position. When in the first position, the water flow moves
through the opening 148 along the first trajectory and toward the
surface of the pool. The actuator 458a can perform this process
each time the heater 26 heats the water flow for a period of
time.
[0079] As shown in FIGS. 9A-9D, the redirector 420a can further
include a biasing member 480a that can be positioned on the second
side of the pivot axis and in communication with the insert 424a
and in particular with the second plate 456b. The biasing member
480a is configured to automatically apply a force to the insert
424a and in particular to the second plate 456a when the water flow
is being heated by the heater 26. Therefore when the water is no
longer being heated the actuator retracts and the biasing member
480a causes the insert to move back to the first position as shown
in FIG. 9C. The biasing member 480a can include a guide 484a
coupled to the housing 60, a rod 486a translatable within the guide
484a, and a spring 488a disposed about the rod 486a. As shown in
FIGS. 9C and 9D, the rod 486a is configured to move between an
extended position when the insert 424a is in the first
configuration and a retracted position when the rotatable insert
424a is in the second configuration, whereby the spring 488a urges
the rod 486a toward the extended position when the rod 486a is in
the retracted position.
[0080] With continued reference to FIGS. 9C and 9D, the actuator
458a is positioned on the first side of the pivot axis and coupled
to the housing 60 such that the actuator 458a is configured to abut
the first plate to thereby cause the rotatable insert 424a to pivot
in a first pivot direction about the pivot axis, and the biasing
member 480a is positioned on the second side of the pivot axis
opposite the first side and coupled to the housing 60 such that the
biasing member 480a is configured to abut the second plate to
thereby bias the rotatable insert 424a in a second pivot direction
about the pivot axis opposite the first pivot direction. Therefore,
the insert 424a can automatically move between the first and second
positions when heat is being applied to the water flow. It should
be appreciated that the biasing member can have other
configurations and is not limited to the illustrated structure. For
example, the biasing member can be a hydraulic strut or a torsion
spring.
[0081] In another embodiment, the redirector can be configured to
change the trajectory of the water flow through the opening by
rotating an insert about an axis that is substantially parallel to
the first direction. As shown in FIGS. 10A-10D, a redirector 520
can include an insert 524 that is rotatably coupled to the housing
60 within the bore of the housing 60. The housing 60 can include a
bearing 525 and the insert 524 can be coupled to the bearing 525
such that the insert 524 is rotatable about an axis 526 that is
substantially parallel to the first direction.
[0082] As shown, the insert 524 includes an insert body 550 that
defines a passageway 554 that extends longitudinally through the
body 550 along a second direction. The distal end of the passageway
554 can define an opening 556 through which the water flow exits.
The second direction can be parallel to the first direction or
angular offset relative to the first direction. The direction in
which the second direction extends depends on the orientation of
the insert 524 within the housing 60. Moreover, because the
redirector 520 changes the trajectory of the water flow by rotating
the insert 524, the second direction will change during
operation.
[0083] As shown, the insert 524 further includes a stop 558 that
extends from the body 550. The stop 558 can be a protrusion that
defines a surface that is configured to be selectively engaged so
as to prevent rotation of the insert 524 about the axis 526. When
the stop 558 is not engaged, the insert 524 will continue to rotate
about the axis 526.
[0084] The redirector 520 can further include an actuator 560 that
is configured to automatically move the rotatable insert 524
between a first position (whereby the opening 556 has the first
configuration) when the water flow is not being heated and a second
position (whereby the opening 556 has the second configuration)
when the water flow is being heated. As shown, the water flow
through the opening 556 has a first trajectory relative to the
first direction when the insert 524 is in the first position, and
the water flow through the opening 556 has a second trajectory
relative to the first direction that is different than the first
trajectory when the insert 524 is in the second position.
[0085] As shown, the actuator 560 includes a thermostatic element
572 that is substantially similar to and functions substantially
similar to the thermostatic element 312. Therefore like the
thermostatic element 312, the thermostatic element 572 includes an
actuator housing 574 and a rod 578 moveable relative to the
actuator housing 574 between a first position and a second
position. The actuator 560 further includes a member 582 that is
coupled to or otherwise in communication with the rod 578 and is
rotatable about a second axis 586 that is substantially
perpendicular to the first direction. The member 582 has a length
that is substantially equal to the diameter of the bore of the
housing 60. The member 582 defines a first end portion 588 and a
second end portion 592 that is opposite to the first end portion
588. The actuator 560 includes a first engagement member 602 that
extends distally from the first end portion 588 and a second
engagement member 606 that extends distally from the second end
portion 592. The first and second engagement members 602 and 606
can be pins that are configured to engage the stop 558. That is,
one of the first and second engagement members 602 and 606 is
engaged with the stop when the insert 524 is in the first position,
and the other of the first and second engagement members 602 and
606 is engaged with the stop 558 when the insert 524 is in the
second position.
[0086] When the water flow is being heated by the heater 26, the
thermostatic element 572 is configured to cause the member 582 to
rotate about the second axis 586 such that the engagement member
602 or 606 becomes disengaged from the stop 558 so as to allow the
rotatable insert 524 to rotate about the first axis 526 and the
other of the first and second engagement members 602 or 606
subsequently engages the stop 558 to thereby prevent the insert 524
from rotating. While the insert 524 can rotate multiple revolutions
about the first axis 526 when the member 582 is rotating about the
second axis 586, it should be appreciated, that the insert 524
effectively rotates about 180 degrees.
[0087] As shown, when the water flow is not being heated by the
heater 26, the water flow moves through the opening 556 along the
first trajectory and toward the surface of the pool. When the
heater 26 is turned on and the water flow is being heated by the
heater 26 the rod 578 moves to the second position thereby causing
the member 582 to rotate about the second axis 586 and cause the
first engagement member 602 to disengage from the stop 558 and the
second engagement member 606 to subsequently engage the stop 558.
The insert 524 rotates about the first axis 526 when the first and
second engagement members 602 and 606 are not engaged with the stop
558. Eventually the second engagement member 606 will be in
position and engage the stop 558 to thereby prevent the insert 524
from rotating. As shown, the insert 524 effectively rotates about
180 degrees and moves from a first position to a second position.
When in the second position, the water flow moves through the
opening 556 along the second trajectory. The actuator 560 can
perform this process each time the heater 26 heats the water flow
for a period of time.
[0088] In another embodiment and in reference to FIGS. 11A and 11B,
the redirector can be configured to redirect the trajectory of the
water flow by moving a hood within an insert. As shown, a
redirector 620 can include an in insert 624 positioned within the
housing 60. The insert 624 can include an insert an insert body 650
that defines a passageway 654 that extends longitudinally through
the body 650 along a second direction. The distal end of the
passageway 654 can at least partially define an opening 656 through
which the water flow exits. The insert 624 further includes a cut
out 658 proximate to a distal end at the bottom of the body
650.
[0089] As shown, the redirector further includes an actuator 660
that is configured to redirect the trajectory of the water flow
through the opening 656 from the first trajectory to the second
trajectory. The actuator 660 includes a hood 664 and a nitinol wire
670 coupled to the hood 664 and configured to move the hood 664
between a first position and a second position when the water flow
is being heated by the heater 26. As shown, the hood 664 includes
an upper hood part 664a and a lower hood part 664b that are each
rotatably coupled to the insert 624 at a first pivot 668. The first
pivot 668 defines a pivot axis that is substantially perpendicular
to the first direction. The upper and lower hood parts 664a and
664b are configured to rotate about the pivot 668.
[0090] The nitinol wire 670 is configured to shorten or otherwise
contract when the water flow is being heated by the heater 26.
Conversely, the nitinol wire 670 is configured to lengthen or
otherwise expand when the water flow is not being heated by the
heater 26. When the wire 670 contracts the hood 664 is pulled
proximally and rotated about the pivot 668 to thereby redirect the
water flow through the opening 656 from the first trajectory to the
second trajectory. When the wire 670 expands the hood 664 is pushed
distally and rotated about the pivot 668 to thereby redirect the
water flow through the opening 656 from the second trajectory back
to the first trajectory. Therefore it can be said that the actuator
660 is configured to automatically move the opening 656 from a
first configuration to a second configuration upon application of
heat to the water flow by the heater 26. It should be appreciated,
however, that the actuator can have other configurations. For
example, the actuator 660 can include a thermostatic element rather
than the nitinol wire to move the hood 664 between the first and
second positions.
