Description
CLAIM OF PRIORITY
[0001] This patent application claims the benefit of priority,
under 35 U.S.C. Section 119(e), to Mirko Zakula et al., U.S. Patent
Application Ser. No. 61/935,781, entitled "VENTILATION SYSTEM AND
METHOD," filed on Feb. 4, 2014, each of which is hereby
incorporated by reference herein in its entirety.
TECHNICAL FIELD
[0002] This document pertains generally, but not by way of
limitation, to ventilation systems and related methods of
installing, replacement or upgrading.
BACKGROUND
[0003] Ventilating exhaust fans, such as those typically installed
in bathrooms, draw air from within an area and pass the exhausted
air out to another location, such as through a vent in the gable or
roof of a home or other building structure. Centrifugal exhaust
fans typically include a rotating fan wheel having a plurality of
vanes that when rotated draw air through an inlet opening in a fan
housing and creates an outward airflow through an outlet opening in
the fan housing. The fan wheel is typically coupled to a motor
supported within the fan housing, which rotates the fan wheel to
provide ventilation for the area. In some cases, a curved fan
scroll is fitted around the fan wheel to guide air the outward
airflow to the outlet opening.
[0004] In certain situations, an installed exhaust fan may need to
be replaced, repaired or upgraded. For example, an old exhaust fan
may need to be replaced when the fan wheel or motor is inoperable
or generating unacceptable vibration or noise during operation.
Similarly, changing ventilation needs may require upgrading to a
more powerful or quieter exhaust fan. The housing for exhaust fans
is often mounted within a building structure, such as in an
aperture in a wall or ceiling. The housing can be secured in the
aperture by being attached to wall or ceiling joists, or by being
attached to other structures in the wall or ceiling. As a result,
exhaust fans can be relatively difficult and time consuming to
remove and replace. In most cases, replacement typically requires
removal of the old ventilation assembly from the wall and install
the new ventilation assembly as well as disconnecting and
reconnecting the associated ductwork. In addition, as exhaust fans
are typically wired directly into the house power supply, a
qualified electrician is often required to disconnect the exhaust
fan from the house power supply and connect the replacement
ventilation assembly to the house power supply.

examples, can be connected to ductwork and electrical wiring. The
cartridge assembly can include a retention feature that can be
releasably engaged to the main housing to retain the cartridge
assembly within the main housing. The cartridge assembly can
include ventilation components such as the motor, fan wheel,
capacitor, controller and various combinations thereof. The
cartridge assembly can be removed from the main housing by
disengaging the retention feature and replaced with a new cartridge
assembly or modified remotely before being reinserted into the main
housing. The cartridge assembly allows repairing or upgrading of
the ventilation assembly without removing the main housing from the
wall or ceiling.
[0006] A ventilation assembly according to an example of the
present subject matter can comprise a main housing and a cartridge

DETAILED DESCRIPTION
[0040] FIGS. 7 and 15 illustrate a ventilation assembly 10
according to one example of the present subject matter. Some
examples of the ventilation assembly 10 can include several
components and devices that can perform various functions. In some
examples, the ventilation assembly 10 can include a main housing
25, which can house the various components and devices of the
ventilation assembly 10. In some examples, the ventilation assembly
10 generally can include a cartridge assembly 20, substantially
housed within the main housing 25, and positioned within the main
housing 25 aided by a fan cartridge locating rib 80, and coupled to
the main housing 25 with a retention feature 85. In some examples,
the cartridge assembly 20 generally can include a motor 30, such as
a permanent split capacitor motor 30, and a motor capacitor 35.
Some examples provide a fan cartridge assembly 20 that can also
include a scroll 40, and a blower wheel 50 positioned substantially
within the scroll 40, and mechanically coupled to the motor 30.
Furthermore, in some examples, a duct connector assembly 270 can be
coupled to the ventilation assembly 10. The duct connector assembly
270 can include a moveable damper flap 280 coupled with a
ventilation orifice 272. In some examples, the damper flap 280 can
control the backflow of a fluid into a ventilation orifice 272 and
the cartridge assembly 20, and further can be capable of
substantially controlling the flow of fluid from a space, such as a
room, into the ventilation duct of a building, or structure, to an
outside location.
[0041] In some examples, the ventilation assembly 10 can be used to
ventilate any room, area or space. In some examples, the
ventilation assembly 10 can be secured within a wall, ceiling, or
other building structure in a partially, or in a fully recessed
position. In some examples, the ventilation assembly 10 can be
installed within an intermediate space, outside of the room, area
or space, and coupled with one or more ventilation duct assemblies
to provide ventilation to the room, area or space. In some other
examples, the fluid can comprise air, or other gases, or vapor,
such as water vapor. In some examples, the fluid can comprise a
smoke, ash, or other particulate in addition to air or other
gases.
[0042] In some examples, the ventilation assembly 10 can be
installed as a new, original equipment installation in a room or
building where none had previously existed, whereas some examples
of the present subject matter provide a ventilation assembly 10
that can replace a pre-existing ventilation system. In some
examples, the cartridge assembly 20, can be installed as a new, or
a replacement ventilation system, and in some examples, the
cartridge assembly 20 can replace an existing cartridge assembly
20.
[0043] As shown in the top perspective view of FIG. 1, in some
examples of the present subject matter, a cartridge assembly 20 can
be provided as a compact assembly comprising a permanent split
capacitor motor 30, motor mounting plate 70, nestled within a
scroll 40, and coupled to a blower wheel 50. In some examples, the
motor 30 can be mechanically secured to the motor mounting plate 70
using at least one motor plate bolt 75, and can be any motor 30
capable of providing sufficient rotational torque to turn the
blower wheel 50. In some examples, the blower wheel 50 can be
mechanically coupled to the motor 30 using a main drive bolt, (see
first end 60 of the main drive bolt in FIG. 1). In some examples,
when a permanent split capacitor motor 30 is used, the motor 30 can
be electrically coupled to at least one permanent split capacitor
35. As shown in FIG. 1, the permanent split capacitor 35 can be
secured to the scroll 40, or in some other examples, it can be
secured to another component of the ventilation assembly 10. In
some examples, the motor 30 is electrically coupled to a motor
power harness 65 that is electrically coupled to the capacitor 35.
In some other examples, the permanent split capacitor 35 can be
secured to a surface of a structure of a building, adjacent to the
cartridge assembly 20, and can be electrically coupled with the
cartridge assembly 20 with a motor power harness 65 (not
shown).
[0044] As shown in the side perspective view of a fan cartridge
assembly 20 of some examples of the present subject matter in FIG.
2, the scroll 40 can be formed into any shape, but generally is
shaped to provide a compact and optimal fluid flow towards the
blower outlet 55 when coupled to the motor mounting plate 70. The
scroll 40 can be formed from any material that is readily shaped,
including, but not limited to, polymers, polymer-composites, metal,
ceramic, or wood, or paper-based composite or laminate.
Furthermore, the use of injection molded or thermo-formed polymeric
materials conveniently allow a variety of functional components to
be included into the structure of the scroll 40. For example, in
some examples, as shown in FIG. 2, the cartridge assembly 20 can
include at least one fan cartridge locating rib 80. The rib 80
provides centering and guidance when maneuvering the cartridge
assembly 20 within a main housing 25 to form the ventilation
assembly 10. In some further examples, other useful features can be
provided. For example, as shown in FIG. 2, in some examples, the
scroll 40 can include a retention feature 85. The retention feature
85 is also shown in more detail in FIG. 5, showing the positional
relationship with respect to the capacitor 35 and the motor power
harness 65. In some examples, the retention feature 85 can be
integral with the scroll 40, and can be used to secure the
cartridge assembly 20 into a main housing 25 of a ventilation
assembly 10. In some other examples, the retention feature 85 is
not integral to the scroll, but a separate component (not shown).
In some examples, the retention feature 85 can be integral with the
scroll 40, however the cartridge assembly 20 can be coupled with
the main housing 25 using alternative methods.
[0045] In some examples, other useful features can be integral with
the scroll 40. For example, as shown in FIG. 3, a screw boss 90 can
be formed. In some other examples, more than one screw boss 90 can
be formed. The screw boss 90 provides an anchoring feature for a
fastener (not shown) to secure the scroll 40 to the motor mounting
plate. In some examples, a surface of the scroll 40 can provide an
anchoring point for other components of the cartridge assembly 20.
For example, one or more screw holes (not shown) can provide an
anchoring location for the motor capacitor 35, while at least one
side of the scroll can provide a mating surface for other
components. As shown in FIG. 3, other surfaces of the scroll 40 can
provide a convenient location for further fan cartridge locating
ribs 80.
[0046] In some examples, one or more integral features of the
scroll can provide an anchoring location for at least one component
of the motor power harness 65. For example, referring to FIG. 4,
showing a side perspective view of a cartridge assembly 20
according to one example of the present subject matter, the motor
power harness 65 can be secured with at least one feature integral
to the scroll. Also shown in FIG. 4, in some examples, the motor
power harness, secured to the scroll 40 can include at least one
plug 67. Referring again to FIG. 5, in some examples, the one or
more wires of the motor power harness 65 can be secured to the
scroll using a component integral to the scroll 40. In some
examples, as shown in FIG. 5, holes can be integral to the scroll
to provide a guide for at least one wire of the motor power harness
65. In some examples, plastic tie-wrap can be used (as shown in
FIG. 5), in addition to other methods, however in other examples,
other methods can be used, such as clips, wire, wrap, or adhesive,
or the like.
[0047] In other examples of the present subject matter, other
useful features can be integral to the scroll 40. For example, the
rear perspective view of a cartridge assembly 20 in FIG. 5 shows an
anchor 100, formed within the body of the scroll. In some examples,
the scroll 40 can include at least one anchor 100. In some
examples, the anchor 100 can be used with a fastener (not shown),
to anchor the upgrade cartridge assembly to the main housing 25. As
described above, in some examples, the scroll 40 can include a
retention feature 85 (also shown in FIG. 5). In some examples, the
retention feature 85 can be used to secure the cartridge assembly
20 into a main housing 25 of a ventilation assembly 10. In some
other examples, the retention feature 85 is not integral to the
scroll, but a separate component (not shown). In some examples, the
retention feature 85 can be integral with the scroll 40, however
the cartridge assembly 20 can be coupled with the main housing 25
using alternative methods, for example, using at least one anchor
100. In some examples, the cartridge assembly 20 can be secured
into the main housing 25 of a ventilation assembly 10 using at
least one anchor 100, and at least one retention feature 85.
[0048] In some further examples of the present subject matter,
other useful features can be formed integral to the scroll 40. For
example, as shown in the side-rear view of a cartridge assembly 20
in FIG. 6A and FIG. 6B, the scroll features a grille spring holder
110 according to one example of the present subject matter.
Referring to the exploded projection view in FIG. 15, in some
examples, the grille spring holder 110 can be used with a spring
115 to conveniently secure a grille 117 to the ventilation assembly
10.
[0049] FIG. 7 is a top perspective view of a ventilation assembly
10 according to one example of the present subject matter. As
discussed earlier, one or more of the examples of the cartridge
assembly 20 as shown in FIGS. 1-5 can be coupled with a main
housing 25 to form a ventilation assembly 10. For example, in FIG.
7, the ventilation assembly 10 is shown in perspective without the
aforementioned grille 117, (shown in FIG. 15). A bottom perspective
view is shown in FIG. 8, showing the bottom side of the main
housing 25. In some examples, the main housing 25 can be formed
into any shape, included but limited to, a rectangular box-like
shape, an oval shape, a hemispherical shape, a spherical shape, a
pyramidal shape, or any other shape. In some examples, the main
housing is formed from a sheet metal, including, but not limited to
an aluminum-based metal, a steel or iron-based metal, a zinc-based
metal, or a nickel and tin-based metal. In some other examples, the
main housing 25 can be formed from injection molded polymers,
thermo-formed polymers, thermosetting polymers, or sheet metal, or
any other suitable material. In some other examples, the housing
can comprise a wood-based product, such as wood, or particle-board
or wood laminate. In some examples, the main housing 25 can form a
base or a similar support structure of the ventilation assembly 10.
Furthermore, in some examples, the main housing 25 can provide
points and areas of attachment for the cartridge assembly 20, or
other components of the assembly 10.
[0050] In some examples, the ventilation assembly 10 can include a
duct connector assembly 270, comprising a first end 274 coupled
with the main housing 25, and the blower outlet 55 (not shown), and
a second end 276, forming a ventilation orifice 272. In some
examples, the duct connector assembly 270 is pre-installed in a
building structure and the duct connector assembly is coupled with
a ventilation duct of a building with the second end 276 of the
duct connector assembly 270. In some examples, the main housing 25
is firstly installed in an existing cavity or aperture of a
structure such as a wall or ceiling. Subsequently the duct
connector assembly 270 is installed by connecting a second end 276
with a ventilation duct of a building, and a first end 274 with an
aperture in the main housing 25 (not shown). Installation is
completed by securing a fan cartridge assembly 20 substantially in
the main housing, positioning the blower outlet 55 adjacent to the
first end 274 of the duct connector assembly 270 installed adjacent
to an aperture of the main housing 25.
[0051] Moreover, as shown in FIG. 7, illustrating a top perspective
view of a ventilation assembly 10 according to one example of the
present subject matter, the duct connector assembly can comprise a
damper flap 280. In some examples, the ventilation assembly 10 can
be operable to discharge fluid flow from a space to another
location. For example, in some examples, when power is provided to
the cartridge assembly 20, a motor 30, such as a permanent split
capacitor motor 30, can rotate a blower wheel 50 positioned
substantially within a scroll 40. Fluid flow is moved substantially
towards the duct assembly, and the moveable damper flap 280 coupled
with a ventilation orifice 272 will open, allowing fluid to be
expelled from the ventilation assembly 10. In some examples, the
damper flap 280 can control the backflow of a fluid into the
ventilation orifice 272 and the cartridge assembly 20, and further
be capable of substantially controlling the flow of fluid from a
space, such as a room, into the ventilation duct of a building, or
structure, to an outside location.
[0052] As discussed previously, some examples of the present
subject matter comprise a cartridge upgrade assembly that includes
a motor mounting plate. For example, as shown in FIG. 9, a bottom
perspective view of a cartridge assembly 20 shows a motor mounting
plate 70 with the fan cartridge upgrade assembly 20 components
mounted to the motor mounting plate 70. In some examples, the
scroll 40 includes at least one screw boss 90 which provides an
anchoring feature for a fastener 73 to secure the scroll 40 to the
motor mounting plate 70. As shown in FIG. 9, a permanent split
capacitor motor 30 is mounted on the opposite side of the motor
mounting plate 70, and the second end 62 of the main drive bolt can
be seen at the base of the motor 30.
[0053] As described previously, it can be desirable to replace an
exhaust fan within a building or structure. For example, an old
exhaust fan may need to be replaced when broken, if the fan
produces excessive vibration or noise during operation. It may be
desirable to replace an old exhaust fan with one that is more
powerful, or has one or more features or characteristics different
than the existing exhaust fan. However, conventional exhaust fans
can be relatively difficult and time consuming to remove and
replace. By providing a ventilation assembly 10 that comprises a
fan cartridge assembly 20 with certain attachment and detachment
features, replacement or upgrade can be a faster and less complex
task. For example, as discussed earlier, some examples of the
present subject matter include a scroll 40 with a retention feature
85 (see FIG. 2 and FIG. 5). In some examples of the present subject
matter, a cartridge assembly 20 is secured into a main housing 25
using at least one retention feature 85. For example referring to
FIG. 10 showing a side perspective view of a ventilation assembly
10 according to one example of the present subject matter, the
retention feature 85 can be seen engaged into an aperture in the
main housing 25. In some examples of the present subject matter,
one or more retention feature 85 can retain the cartridge assembly
20 in a main housing 25 without the use of additional tools or
hardware. As discussed previously, the retention feature 85 can be
an integral part of the scroll 40, or can be a separate component.
FIG. 10B shows a close-up view of a side of a ventilation assembly
10 according to one example of the present subject matter, and the
retention feature 85 can be seen exiting the main housing 25. FIG.
10C is a close-up top view of the ventilation assembly 10 according
to one example of the present subject matter showing a retention
feature 85 as an integral part of the scroll 40, engaged with the
main housing 25. Some examples of the present subject matter
provide a ventilation exhaust fan comprising a fan cartridge
assembly 20 having at least one permanent split capacitor motor, at
least one permanent split capacitor electrically coupled to the
motor, a motor harness including at least one plug, and a blower
wheel coupled with a scroll, coupled with the motor to generate a
flow of fluid out of the fluid outlet. In some examples, the motor
30 is electrically coupled to a motor power harness 65 that is
electrically coupled to the capacitor 35. In some examples, the
cartridge assembly 20 can be installed within an intermediate
space, outside of the room, area or space, and coupled with one or
more ventilation duct assemblies to provide ventilation to the
room, area or space. In some examples, the cartridge assembly 20,
can be installed as a new, or a replacement ventilation system, and
in some examples, the cartridge assembly 20 can replace an existing
cartridge assembly 20. Furthermore, in some examples, the main
housing 25 can provide points and areas of attachment for the
upgrade cartridge assembly, or other components of the assembly 10.
In some examples, when the main housing 25 is installed, an
electrical box enclosure 210 is positioned within the main housing
to provide a source of electrical power to the capacitor 35 and
motor 30. In some examples, the electrical box enclosure 210 can
comprise an electrical box cover plate 200, an electrical box
anchoring tab 240 to secure the electrical box cover plate 200 to
the electrical box enclosure 210. The electrical box cover plate
200 can be seen in more detail in FIG. 12. As show, in some
examples, electrical box attachment screw holes 230a and 230b are
included and used with a fastener (not shown) to secure the
electrical box cover plate 200 to the main housing 25. Furthermore,
electrical box anchors 220a and 220b can be used to anchor the
electrical box enclosure 210 to the main housing 25. In some
examples, the electrical box enclosure 210 includes a power
receptacle 250.
[0054] In some examples, when the main housing 25 is installed, an
electrical box enclosure 210 is positioned within the main housing
and the internal wiring of the main housing (not shown) is coupled
with an electrical power supply to supply electrical power to the
power receptacle 250. As described earlier, in some examples of the
present subject matter, a fan cartridge assembly 20 can include a
motor power harness 65 that can be secured, with at least one
feature integral to the scroll. Also shown in FIG. 4, in some
examples, the motor power harness, secured to the scroll 40 can
include at least one plug 67.
[0055] In some examples of the present subject matter, the main
housing can be pre-installed by inserting into a cavity or aperture
of a structure. In some examples, following assembly and
installation of at least the main housing 25, the installer can
connect one or more terminals of the power receptacle 250 to an
external source of electrical power. The electrical box enclosure
210 and the electrical box cover plate 200 can be fully assembled,
and the power receptacle 250 can be coupled to the external power
source. The installer can maneuver the cartridge assembly 20 in the
main housing 25 and the plug 67 can be coupled with the power
receptacle 250. In some examples, the plug 67 can be coupled with
the power receptacle 250, and then the installer can maneuver the
cartridge assembly 20 in the main housing 25. In some examples,
once the cartridge assembly 20 has been maneuvered into the main
housing 25, one or more cartridge snap retention features 85 can be
used to secure the cartridge assembly 20 into a main housing 25 of
a ventilation assembly 10. In some other examples, the ventilation
assembly 10 can be fully assembled and installed directly into a
cavity or aperture of a structure.
[0056] As discussed earlier, in some examples of the present
subject matter, the ventilation assembly 10 can include a duct
connector assembly 270, comprising a first end 274 coupled with the
main housing 25, and the blower outlet 55, and a second end 276,
forming a ventilation orifice 272. In some examples, the main
housing 25 is firstly installed in an existing cavity or aperture
of a structure such as a wall or ceiling. Subsequently, the duct
connector assembly 270 is installed by connecting a second end 276
with a ventilation duct of a building, and a first end 274 with an
aperture in the main housing 25 (not shown). Installation is
completed by securing a fan cartridge assembly 20 substantially in
the main housing, positioning the blower outlet 55 adjacent to the
first end 274 of the duct connector assembly 270 installed adjacent
to an aperture of the main housing 25. In some examples, the duct
connector assembly 270 is pre-installed in a building structure and
not pre-installed in the main housing 25 of a ventilation assembly
10. As shown in FIG. 13A and FIG. 13B, in some examples, the duct
connector assembly 270 can comprise damper flap 280 that is
rotatable within the duct connector assembly 270, and in some
examples, can further include a duct snap mounting assembly 290. In
some examples, the ventilation assembly 10 can be fully assembled
and include a duct connector assembly 270 including a duct snap
mounting assembly 290. As shown in FIG. 14A, one example showing a
close-up view of a duct connector 270 assembly installed in a main
housing 25 viewed from within the main housing 25, with the duct
snap mounting assembly 290 forcibly securing the duct connector
assembly 270 to the main housing 25. FIG. 14B and FIG. 14C show the
outside view of the fully assembled ventilation assembly 10. FIG.
14B is a close-up view of a duct connector assembly installed in a
main housing according to one example of the present subject
matter, and shows a duct connector tab 295 coupled with the main
housing 25 when the duct connector assembly 270 is fully installed
in the main housing 25. FIG. 14C is a close-up view of a duct
connector assembly installed in a main housing according to one
example of the present subject matter showing a portion of the duct
snap mounting assembly 290 extending outside of an aperture in the
main housing 25 as the assembly 290 forcibly secures the duct
connector assembly 270 to the main housing 25.
[0057] FIG. 15 shows an exploded view of a ventilation assembly 10
according to one example of the present subject matter. Referring
to the exploded projection view showing the grille spring holder
110, (shown previously for example in the side-rear view of a fan
cartridge assembly 20 in FIG. 6A and FIG. 6B), once the ventilation
assembly installation has been completed, a spring 115 can be used
to conveniently secure a grille 117 to the ventilation assembly 10.
In some other examples, the grille 117 can be secured to the
ventilation assembly 10 with more than one spring 115 and more than
one grille spring holder 110. In some other examples, the grille
117 can be secured to the ventilation assembly 10 by some other
component, such as a clip, a wire, a wrap, or adhesive, or the
like. In some examples, the grille 117 can be formed from injection
molded polymers, thermo-formed polymers, thermosetting polymers, or
sheet metal, or any other suitable material.
[0058] Some examples of the present subject matter provide a
ventilation assembly 11 comprising alternative examples of the
upgrade cartridge assembly 22. For example, FIGS. 16 and 17 show
exploded views of ventilation exhaust fan assembly 11 according to
another example of the present subject matter, and FIGS. 18 and 19
show exploded views of the upgrade cartridge assembly 22 according
to another example of the present subject matter. In this instance,
the upgrade cartridge assembly 22 can include a motor bracket that
is an integral part of the motor plate 71. As used herein,
"integral" means a single, substantially homogenous piece of
material manufactured in one step.
[0059] Moreover, the assembly 22 can be provided to a customer so
that there is no need to assemble the blower. This is different
from the cartridge assembly 20 described earlier, and illustrated
in FIGS. 3-5, and 9. In some examples, the ventilation assembly 10
generally can include an upgrade cartridge assembly 22,
substantially housed within the main housing 25, and positioned
within the main housing 25. Furthermore, in some examples, the main
housing 25 can provide points and areas of attachment for the
cartridge assembly 20, or other components of the assembly 11.
[0060] In some examples, the upgrade cartridge assembly 22
generally can include a motor 30, such as a permanent split
capacitor motor 30, and a motor capacitor 35. Some examples provide
a ventilation assembly 11 that can also include a scroll portion 41
that can be integral with the housing 25, and a blower wheel 50
mechanically coupled to the motor 30.
[0061] In some examples, the ventilation assembly 11 can be
operable to discharge fluid flow from a space to another location.
For example, in some examples, when power is provided to the
upgrade cartridge assembly 22, the motor 30 can rotate the blower
wheel 50 positioned substantially within the scroll portion 41 of
the housing 25. Fluid can be moved substantially towards the outlet
27. A duct assembly (such as the duct assembly 270 with moveable
damper flap 280) can be coupled to the outlet 27, and the flap 280
can open, allowing fluid to be expelled from the ventilation
assembly 11. In some examples, the damper flap 280 can at least
partially control the backflow of a fluid into the upgrade
cartridge assembly 22, and can further be capable of substantially
controlling the flow of fluid from a space, such as a room, into
the ventilation duct of a building, or structure, to an outside
location. FIG. 20A shows a top view of a motor plate 71
illustrating cross-sections cut lines according to one example of
the present subject matter. As described earlier, a motor bracket
can form an integral part of the motor plate 71. Moreover, the
plate forms a deep inlet venturi that can straighten air as it
flows into the wheel 50, and can allow the use of a wider blower
wheel 50. Cross-sectional views of the plate 71 enable the geometry
of the plate to be visualized in more detail. For example, FIGS.
20B-20E include views of the motor plate 71 of the upgrade
cartridge assembly 22. FIG. 20B illustrates a cross-sectional view
of the motor plate 71 of FIG. 20A through the cut line 18-18, and
FIG. 20C illustrates a cross-sectional view of the motor plate 71
of FIG. 20A through the cut line 17-17 according to one example of
the present subject matter. Further, FIG. 20D illustrates a
cross-sectional view of the motor plate 71 of FIG. 20A through the
cut line 19-19, and FIG. 20E illustrates a cross-sectional view of
the motor plate 71 of FIG. 20A through the cut line 15-15 according
to one example of the present subject matter. As illustrated, the
motor plate 71 includes a cross-member positioned substantially
centrally across the fluid flow inlet aperture. The motor plate 71
functions similarly to a conventional motor bracket to support the
motor 30. However, the cross-member includes a bracket region that
is inwardly raised and therefore can enable an attached motor 30 to
be moved closer to the blower wheel 50.
[0062] In some examples, the inwardly raised bracket region can
include motor mounting apertures and a motor drive shaft aperture.
Further, some examples of the cross-member can include flared
portions at each end coupled to the inner rim of the inlet
aperture. In some examples, the cross-member can include a
plurality of substantially smooth and contoured surfaces. For
example, the flared regions as coupled to the inner rim of the
inlet aperture can be substantially smooth and contoured, and the
transition regions extending to the bracket regions can be
substantially smooth and contoured. The smooth and contoured
regions can reduce the operating noise of the ventilation assembly
11 by providing more laminar flow over the motor plate and into the
blower wheel 50.
[0063] In some examples, the cross-member including the inwardly
raised bracket region can be generally inwardly angled so as to be
generally positioned closer to the blower wheel 50. In fact in some
examples, the upper surface of the cross-member can be positioned
in substantially the same plane as the upper surface of the outer
region of the motor plate 71, and the lower surface of the
cross-member can be positioned in substantially the same plane as
the lower surface of the outer region of the motor plate 71 (i.e.,
substantially all of the bracket region is positioned between a
region defined between the upper and lower surfaces of the outer
region of the motor 71.
[0064] Some examples of the ventilation assembly 11 include a
coupled grille. For example, as shown in the exploded views of
FIGS. 16 and 17, the ventilation exhaust fan assembly 11 can
include a grille 118. Further, FIGS. 21A-21E illustrate various
views of a ventilation assembly grille 118 according to another
example of the present subject matter. In some examples, following
installation, a spring can be used to conveniently secure the
grille 118 to the ventilation assembly 11. In some other examples,
the grille 118 can be secured to the ventilation assembly 11 with
more than one spring 115, and more than one grille spring holder.
In some other examples, the grille 118 can be secured to the
ventilation assembly 11 by some other component, such as a clip, a
wire, a wrap, or adhesive, or the like. The grille 118 can be
formed from materials as outlined above for the grille 117
including injection molded polymers, thermo-formed polymers,
thermosetting polymers, or sheet metal, or any other suitable
material.

connection with particular examples and examples, the present
subject matter is not necessarily so limited, and that numerous

computer-readable medium or machine-readable medium encoded with
instructions operable to configure an electronic device to perform
methods as described in the above examples. An implementation of
such methods can include code, such as microcode, assembly language
code, a higher-level language code, or the like. Such code can
include computer readable instructions for performing various
methods. The code may form portions of computer program products.
Further, in an example, the code can be tangibly stored on one or
more volatile, non-transitory, or non-volatile tangible
computer-readable media, such as during execution or at other
times. Examples of these tangible computer-readable media can
include, but are not limited to, hard disks, removable magnetic
disks, removable optical disks (e.g., compact disks and digital
video disks), magnetic cassettes, memory cards or sticks, random
access memories (RAMs), read only memories (ROMs), and the
like.
[0105] The above description is intended to be illustrative, and
not restrictive. For example, the above-described examples (or one
or more aspects thereof) may be used in combination with each
other. Other examples can be used, such as by one of ordinary skill
in the art upon reviewing the above description. The Abstract is
provided to comply with 37 C.F.R. .sctn.1.72(b), to allow the
reader to quickly ascertain the nature of the technical disclosure.
It is submitted with the understanding that it will not be used to
interpret or limit the scope or meaning of the claims. Also, in the
above Detailed Description, various features may be grouped
together to streamline the disclosure. This should not be
interpreted as intending that an unclaimed disclosed feature is
essential to any claim. Rather, inventive subject matter may lie in
less than all features of a particular disclosed example. Thus, the
following claims are hereby incorporated into the Detailed
Description as examples or examples, with each claim standing on
its own as a separate example, and it is contemplated that such
examples can be combined with each other in various combinations or
permutations. The scope of the present subject matter should be
determined with reference to the appended claims, along with the
full scope of equivalents to which such claims are entitled.
