FIELD OF THE INVENTION
[0002] The field of the invention is drainage methods, systems, and
devices.
BACKGROUND
[0003] The background description includes information that may be
useful in understanding the present invention. It is not an
admission that any of the information provided herein is prior art
or relevant to the presently claimed invention, or that any
publication specifically or implicitly referenced is prior art.
[0004] It is common in the use of sinks and other systems with open
drains for debris, such as food scraps, to flush into the drain.
Such debris has the potential to obstruct the drainage pipes, and
so it is common to include a grinding device such as a garbage
disposal to pulverize the debris. However, these grinding devices
are generally loud when operated alone and can be louder depending
on the type of debris being pulverized. Further, it is non-uncommon
for the grinding device to cast debris fragments out of the drain
during operation. Attempts have been made to solve the noise and
debris fragment problem of garbage disposals, but the solutions
have been lacking.
[0005] It is known to incorporate a twist valve into sink drains.
Such devices are opened or closed primarily in an effort to start
and stop the flow of debris through the drain. However, such
devices can be manually opened and closed before and after
activating a garbage disposal. While such valves can be effective
at reducing noise, it is not appealing to the consumer market
because they require active, manual use rather than providing a
passive, automatic noise reduction.
[0006] Duck bill valves offering passive valve closure include U.S.
Pat. No. 6,401,266 to Mitchell et al.; U.S. Pat. Appl. No.
2006/0010565 to Cummings (publ. May 2006); U.S. Pat. Appl. No.
2006/0207005 to Janssen (publ. September 2006); and WIPO Patent
Appl. No. 2009/040524 to McAlpine (publ. April 2009). However, the
known duck bill valves are not well suited to permit the passage of
larger sized debris. Further, duck bill valves tend to retain a
small amount of fluid after each use which could lead to mold or
odors.
[0007] All publications herein are incorporated by reference to the
same extent as if each individual publication or patent application
were specifically and individually indicated to be incorporated by
reference. Where a definition or use of a term in an incorporated
reference is inconsistent or contrary to the definition of that
term provided herein, the definition of that term provided herein
applies and the definition of that term in the reference does not
apply.
[0008] Thus, there remains a need for a system and method that
provides passive closure of sink drains, while still permitting the
passage of larger food debris, such that the noise of operating a
garbage disposal is reduced.
SUMMARY OF THE INVENTION
[0009] The inventor has now discovered that placing a valve
upstream of a garbage disposal very significantly reduces
user-perceived sound emanating from use of the disposal, as well as
reducing or preventing the ejection of food fragments from the
disposal.
[0010] Various objects, features, aspects and advantages of the
inventive subject matter will become more apparent from the
following detailed description of preferred embodiments, along with
the accompanying drawing figures in which like numerals represent
like components.
[0011] In one aspect, the inventive subject matter generically
contemplates a grinding device having a valve and a grinding
chamber.
[0012] In preferred embodiments, the valve is a downwardly-sloping,
gravity flow valve, which is configured to be biased to a closed
position. As used herein, the term "gravity flow valve" means a
valve in which fluid and debris flows through the valve primarily
as a result of the force of gravity. Such valves preferably remain
closed unless opened when a pressure of a fluid or debris on an
upper surface of the valve exceeds a predetermined threshold. This
is beneficial because the valve opens when fluid or debris is
present on the surface of the valve, but otherwise remains closed,
which advantageously reduces the operating noise of a grinding
device as perceived by the operator.
[0013] The valves, diaphragms, conical barriers, and other
components of the embodiments discussed throughout this application
can be constructed of a pliant material. In preferred embodiments
of the inventive concept the components are constructed of a
material that is resistant to decomposition, oxidation, and/or
biological activity. Suitable materials include mold resistant
rubber, silicone, nitrile rubber, polyethylene, a
perfluoroelastomer, an ethylene acrylate elastomer, and
polychloroprene. It should be appreciated that various components
of the inventive subject can comprise different or substantial the
same materials.
[0014] In preferred embodiments, grinding chambers have blunt or
bladed arm that rotates within a partially enclosed chamber. Some
contemplated grinding chambers are adapted to grind food. Where
such devices are fluidly coupled to a drain, the chambers include
garbage disposals. As used herein, "garbage disposal" has its
ordinary meaning as exemplified by the InSinkErator.TM.. Other
contemplated grinding chambers are of the type used to process
food, such as blenders, mixers, and food processors, and in such
instances the grinding chambers are not usually coupled to a drain.
In still other instances, contemplated grinding chambers include
devices used to grind non-food debris, for example, yard clippings,
stone, gravel, ice, plant fibers, and wood. It should be
appreciated that the operation of such devices is associated with
noise, which at times is extremely loud and disturbing. In addition
to noise, some grinding devices or grinding substrate/debris create
the risk of substrate/degree fragments being ejected from the
device while in operation.
[0015] Contemplated valves and grinding chambers can be coupled in
any suitable manner. Valves will typically be disposed in a valve
house, having an outer surface configured to form a seal when
inserted into an opening, such as a drain. In some embodiments, the
outer surface includes grooves that mate with the grooves of a sink
drain or grooves on a garbage disposal. In some embodiments, the
outer surface includes rubberized baffles that form a snug fit when
inserted into an opening. It is contemplated that the seal formed
between the housing and the opening may be formed by a chemical
bond, a magnetic attraction, an electromagnetic force, friction,
gravity, adhesion, suction, spring, or other appropriate means.
[0016] As used herein, the term "drain" means a fluid outlet such
as that found in urinals, sinks, tubs, floor drains, or other
drains through which fluid can flow. The term "fluidly connected"
means a connection which permits the passage or flow of a
fluid.
[0017] In one aspect, the inventive subject matter contemplates a
method for reducing the volume of noise caused by a grinding
device. The noise caused by a grinding device could be from
operating a food grinder, garbage disposal, food processor, or
other grinding device as referenced throughout this application.
The method can involve directing a substance, for example food or
other debris, through a housing. In preferred embodiments, the
housing comprises a valve biased to a closed position. Directing
the substance through the housing can be accomplished by, for
example, flushing the substance with a fluid as well as placing,
pushing, dropping, or otherwise causing the substance to move
through the housing. In preferred embodiments the substance is food
debris, but can also be any of the other types of debris referenced
in this application. In some embodiments, the method further
comprises activating a grinding device. In preferred embodiments,
the method includes flushing food debris through a gravity flow
valve and into a garbage disposal.
[0018] In one aspect, the inventive subject matter contemplates a
method for reducing or preventing substrate/debris fragments from
being cast out of a grinding device. The projected fragments
emitted from a grinding device could be from operating a food
grinder, garbage disposal, food processor, or other grinding
device. The method can involve directing a substrate, for example
food or other debris, through a housing having a valve biased to a
closed position. Directing the substrate through the housing can be
accomplished by, for example, flushing the substrate with a fluid
as well as placing, pushing, dropping, or otherwise causing the
substance to move through the housing. In preferred embodiments the
substance is food debris, but can also be any of the other types of
debris as appropriate for the grinding device. The method can
include activating the grinding device. In preferred embodiments,
the method includes flushing food debris through a gravity flow
valve and into a garbage disposal.
[0019] In one aspect of the inventive subject matter, a system for
grinding is contemplated. In some embodiments, the system is a food
disposal system. In some embodiments, the system can include a
basin having an opening in the bottom of the basin, a grinding
device, and a skirted valve between the opening in the basin and
the grinding device. Viewed from one perspective, the system
comprises a channel having a sink, a drain, a skirted valve, and a
garbage disposal unit, in sequence. The basin can be a bowl, dish,
bucket, sink, vat, tank, or other receptacle. In some embodiments,
the opening in the basin is sized such that debris of the types
referenced throughout this application can fit in and through the
opening.
[0020] In preferred embodiments, the housing is sized and
dimensioned such that at least a partial seal is formed between the
housing and the opening in the basin. In some embodiments, the
housing forms at least a partial seal between the housing and the
grinding device. In some embodiments, the housing is removable from
the basin or the grinding device. In some embodiments, the skirted
valve is threadedly coupled to a garbage disposal unit. Threadedly
coupled could include both the valve screwed directly into the
disposal unit, as well as the valve indirectly threaded by use of
bolts, nuts, or screws.
[0021] In some embodiments, the skirted valve is housed in a
consumer replaceable cartridge. A consumer replaceable cartridge is
one with simplified removal and replacement mechanisms. For
example, the replacement mechanism is such that no tools are
required to remove and replace the cartridge. Further, a
consumer-replaceable cartridge can include a mechanism that
requires the use of simple tools such as a wrench, screwdriver,
pliers, or a pry bar to remove and replace the cartridge. It is
contemplated that the cartridge fit into a receptacle as-is, though
it should be appreciated that an adaptor can be used as
appropriate. Connectors or screws are used to couple the cartridge
to the receptacle, but other fasteners are also contemplated. The
cartridge receptacle can be part of a sink drain or part of a
grinding chamber.
[0022] In one aspect of the inventive subject matter, a method for
sealing a chamber is contemplated. In some embodiments, the chamber
can be an enclosed grinding device of the type referenced in this
application. In preferred embodiments, the chamber is an enclosed
garbage disposal device. In some embodiments, the method comprises
fluidly directing a plurality of debris into a housing. In some
embodiments, both the housing and the debris can be of the types
described in this application. In preferred embodiments, after the
debris has passed through the housing and into the chamber, a valve
within the housing moves to a closed position, preferably
automatically or otherwise without the direction of a user. The
closed position at least partially seals the chamber.
[0023] In one aspect of the inventive subject matter, a method for
reducing an operating noise is contemplated. In some embodiments,
the method includes providing a skirt valve disposed within a
housing. In some embodiments, the skirt valve has an inlet through
which debris can enter the valve, and an outlet through which
debris can exit the valve. A skirt valve of the inventive concept
includes a conical barrier. In such a device a conical barrier can
be shaped as a frustum of a cone. In some embodiments, the conical
barrier has an aperture located centrally in the smaller upper
base, which is used in mounting the barrier. In preferred
embodiments the upper base is positioned toward the valve inlet. In
some embodiments the conical barrier is constructed of a pliant
material, the thickness of which can decrease between the smaller
upper base and the larger lower base. As such, in addition to being
pliant the conical barrier can have a pliancy that changes along
its axis (for example, having increased pliancy towards the larger
lower base). In some embodiments, the conical barrier can be
mounted by means of a central aperture located in the upper base.
In a preferred embodiment the conical barrier is mounted on a
central shaft that passes through the aperture. In some embodiments
the central shaft is positioned within the body of the skirt valve.
In some embodiments, a portion of the conical barrier proximal to
the lower base is biased to a position abutting a sealing surface
of the valve body. In some embodiments, the lower base and sealing
surface are positioned toward the valve outlet. The conical barrier
can be constructed of a pliant material, which permits fluids to
flow past the conical barrier by moving it away from the sealing
surface as pressure is applied to the upper surface of the conical
barrier.
[0024] In further embodiments of a method to reduce operating
noise, a flow of fluid is directed through the skirt valve. In some
embodiments the fluid can be directed through gravity, pressure,
suction, or another appropriate force. In some embodiments of a
method to reduce operating noise, the conical barrier returns to a
closed position abutting the sealing surface after the fluid has
passed the conical barrier.
[0025] In some embodiments, a method for guiding a person to muffle
sound emitted from a garbage disposal is contemplated. Such methods
include providing a gravity flow valve that is biased to a closed
position. The valve opens automatically when pressure is applied to
a top surface of a diaphragm portion of the gravity flow valve.
Instructions are further provided directing the person to utilize
the gravity flow valve in conjunction with a garbage disposal, such
that food entering the gravity flow valve passes through the
gravity flow valve, and subsequently into the garbage disposal. In
some embodiments, a kit comprising the gravity flow valve and
garbage disposal is further sold to a person, where the valve and
disposal can be uncoupled or physically coupled. It is contemplated
that the gravity flow valve be disposed in a cartridge, and further
instructions are provided for replacing or installing the
cartridge.
[0026] As used in the description herein and throughout the claims
that follow, the meaning of "a," "an," and "the" includes plural
reference unless the context clearly dictates otherwise. Also, as
used in the description herein, the meaning of "in" includes "in"
and "on" unless the context clearly dictates otherwise.
[0027] As used herein, and unless the context dictates otherwise,
the term "coupled to" is intended to include both direct coupling
(in which two elements that are coupled to each other contact each
other) and indirect coupling (in which at least one additional
element is located between the two elements). Therefore, the terms
"coupled to" and "coupled with" are used synonymously.
[0028] All methods described herein can be performed in any
suitable order unless otherwise indicated herein or otherwise
clearly contradicted by context. The use of any and all examples,
or exemplary language (e.g. "such as") provided with respect to
certain embodiments herein is intended merely to better illuminate
the invention and does not pose a limitation on the scope of the
invention otherwise claimed. No language in the specification
should be construed as indicating any non-claimed element essential
to the practice of the invention.
[0029] Groupings of alternative elements or embodiments of the
invention disclosed herein are not to be construed as limitations.
Each group member can be referred to and claimed individually or in
any combination with other members of the group or other elements
found herein. One or more members of a group can be included in, or
deleted from, a group for reasons of convenience and/or
patentability. When any such inclusion or deletion occurs, the
specification is herein deemed to contain the group as modified
thus fulfilling the written description of all Markush groups used
in the appended claims.
[0030] The discussion throughout this application provides many
example embodiments of the inventive subject matter. Although each
embodiment represents a single combination of inventive elements,
the inventive subject matter is considered to include all possible
combinations of the disclosed elements. Thus if one embodiment
comprises elements A, B, and C, and a second embodiment comprises
elements B and D, then the inventive subject matter is also
considered to include other remaining combinations of A, B, C, or
D, even if not explicitly disclosed.

DETAILED DESCRIPTION
[0047] The inventive subject matter provides apparatus, systems,
and methods providing passive closure of drains while allowing food
debris to pass through the drain. The desired effect of this
passive closure is, in part, reduced volume or reduced ejection of
fragments from grinding device when it is operated.
[0048] The following discussion provides many example embodiments
of the inventive subject matter. Although each embodiment
represents a single combination of inventive elements, the
inventive subject matter is considered to include all possible
combinations of the disclosed elements. Thus if one embodiment
comprises elements A, B, and C, and a second embodiment comprises
elements B and D, then the inventive subject matter is also
considered to include other remaining combinations of A, B, C, or
D, even if not explicitly disclosed.
[0049] In FIGS. 1A-1C, one embodiment of a device 100 is shown for
reducing the ejection of debris fragments or the sound of operating
a grinding device that includes a housing 102 having multiple
openings 122 disposed on an upper surface 112 of the housing 102.
It is contemplated that the upper surface 112 can be downwardly
sloped to direct fluid toward openings 122. The housing 102 can be
composed of any commercially suitable material(s) including, for
example, plastics and other polycarbonates, metal, quartz,
porcelain, and any combination(s) thereof.
[0050] In some contemplated embodiments, housing 102 can be sized
and dimensioned to fit within a drain such as those found in sinks,
urinals, and floor drains, for example. However, it is
alternatively contemplated that the device 100 can be sized and
dimensioned to fit within a cartridge. Although housing 102
preferably has a horizontal cross-section that is circular in
shape, the shape of the housing 102 can be varied to correspond to
the shape of the drain or cartridge.
[0051] Device 100 can include an outwardly projecting flange 114
that can be used to allow the device 100 to rest on a portion of a
cartridge or drain. Optionally, a pliable plastic or elastomeric
seal ring 146 can be disposed about at least a portion of the
flange 114 to create a fluid seal. Device 100 can further include
threads 127 that are configured to mate with threads of a drain or
cartridge, such that the device 100 can be secured in place. In
this manner, the device 100 can be removably threaded and thereby
secured or removed from, a drain or cartridge. However, other
commercially suitable fasteners could be substituted for threads
127 such that the device 100 can be secured in place.
[0052] Device 100 can advantageously include first and second
valves 136 and 138 disposed in housing 102, which are configured to
prevent sound from emanating from downstream of the device 100.
FIG. 1C depicts a device 100 advantageously having only one valve,
valve 136. It is contemplated by the inventive subject matter that
embodiments could include at least one valve, such as valve 136.
However, dual valve systems are contemplated that optionally
provide additional protection against the escape of sound or
ejection of debris fragments through the drain. For example, even
if the primary first valve 136 was somehow stuck open by a
toothpick or other debris, the secondary valve 138 would still
prevent downstream sound or debris fragments from escaping from the
device 100.
[0053] Preferably, each of the valves 136 and 138 is coupled to a
stem 130, and in some contemplated embodiments, the stem 130 can
extended through each of the valves 136 and 138.
[0054] Optionally, as shown in FIG. 1B, the stem 130 can include a
bump or extended portion 140 disposed beneath each of the valves
136 and 138. The bumps or extended portions 140 can help support
the valves 136 and 138, especially where the valves have a diameter
greater than 4'' or a thickness that is sufficiently thin to cause
the valves 136 and 138 to otherwise collapse under normal flow.
Alternatively or additionally, stem 130 can include first and
second recessed portions 142 and 144 sized and dimensioned to
receive the first and second valves 136 and 138, respectively.
[0055] In preferred embodiments, each of the valves 136 and 138 is
a gravity flow valve that is biased closed such that the valves 136
and 138 are closed when not in use. Such valves advantageously can
operate without electricity, and function to create a closed
system, where the valves close automatically once the fluid or
debris passes through the valves. The valves 136 and 138 can have a
flexible membrane that can comprise any commercially suitable
material(s) including, for example, silicon fabric or other
synthetic, natural, and/or flexible materials, or combinations
thereof, which provide protection to the valves from significant
damage or degradation by debris and cleaning solvents. It should be
appreciated that suitable materials for the valves include
materials that provide both rigidity and flexibility. The valves
136 and 138 can be used to regulate various fluids including, for
example, water, cooking fluids, cleaning fluids, fluids carrying
substrates such as food debris, and combinations thereof.
[0056] It is especially preferred that each of the valves 136 and
138 is a skirt valve, which has a downwardly-sloping rim extending
from a center portion of the valve where the rim has a flexible
outer portion. As used herein, the term "downwardly-sloping" refers
to sloping in the direction of predominant fluid flow, which might
or might not be downward in a gravitational sense, depending on the
orientation of the valve.
[0057] It should be appreciated that housing 102 of FIGS. 1A-C can
have different configurations. For example, housing 102 can have
the configuration and features of valve cartridge 1270, valve
housing 1300, or valve housing 1400, as depicted in FIGS. 12B, 13,
and 14 and described below.
[0058] A sample embodiment of a skirt valve is shown in FIGS.
5A-5C. Skirt valves possess numerous advantages over other one-way
valves such as umbrella valves and duckbill valves. For example,
the skirt valve can be mounted about a stem or post to create a 360
degree opening that is less likely to be jammed by solid items. In
addition, the skirt valve typically lacks a spoke to hold the
center of the valve in place, and therefore lacks the problems
associated with the spokes catching foreign objects. Furthermore,
the skirt valve can have a thicker first portion that is coupled to
a stem or post of the cartridge, and a thinner second portion that
allows for greater flexibility of the valve. In this manner, the
skirt valve can be (1) much more rigid than an umbrella valve to
(a) keep the valve closed when not in use and (b) prevent back
pressure in the drain from opening the valve, while (2) the ends of
the skirt valve are flexible enough to allow for fluid flow or
debris to pass through the valve.
[0059] Although less preferred, other commercially suitable valves
could be used including, for example, umbrella valves, duck bill
valves, and other flexible valves.
[0060] It is especially preferred that the valves 136 and 138 can
be disposed within housing 102 such that an end portion of each of
valves 136 and 138 is seated beneath first and second
downwardly-sloping valve seats 194 and 196 of housing 102,
respectively. In this manner, any backflow or pressure beneath the
valves 136 and 138 will keep one or both of the valves 136 and 138
pressed against respective valve seats 194 and 196, and thus the
valves 136 and 138 remain sealed preventing downstream liquids,
gases, debris, or sounds from getting past the valves 136 and
138.
[0061] The valves 136 and 138 are preferably tapered, such that
each valve has a varying thickness along its respective radius. In
this manner, the valves 136 and 138 can each comprise a rigid inner
portion 137B and 139B with a flexible outer edge interval 137A and
139A, respectively. In some contemplated embodiments, each of the
valves 136 and 138 can include an outer edge interval of 5 mm that
is sufficiently thin to allow even small amounts of fluid or debris
to pass by valves 136 and 138, while retaining sufficient strength
for durability at inner portions 137B and 139B, respectively.
Preferably, the outer edge intervals 137A and 139A of the first and
second valves 136 and 138 has an average thickness that is less
than 95%, and more preferably less than 90% and in some embodiments
less than 80%, of an average thickness of the inner portions 137B
and 139B, respectively.
[0062] In especially preferred embodiments, the outer 5 mm edge
interval 137A of the first (upper) valve 136 has a first average
thickness that is less than 95% of a second average thickness of
the outer 5 mm edge interval 139A of the second (lower) valve 138.
As used herein, the term "outer 5 mm edge interval" means the
portion extending from the outer edge of the valve inwards by a
distance of 5 mm. For example, the outer 5 mm edge interval of a
circular valve having a radius (r) of 20 mm is the outer 15-20 mm
from a center of the circular valve, or an area represented by the
formula: (.pi.*r.sup.2)-(.pi.*(r-5).sup.2). In this example, the
area would be approximately 549.8 mm. Similarly, the term "outer 1
mm edge interval" means the outer 1 mm edge portion extending about
an exterior of the valve. One of ordinary skill in the art would of
course understand that square, ovular, and other commercially
suitable sizes and dimensions of valves could alternatively be
used, and the outer x edge interval would still be applicable.
[0063] It is further contemplated that the first average thickness
of the outer edge interval could be less than 90%, 85%, 80%, 75%,
or 70% of the second average thickness of the second outer 5 mm
edge interval 139A. It is further contemplated that the flexible
edge interval of the valve could be the outer 1 mm, 3 mm, 7 mm, 10
mm, 15 mm, 20 mm, and so forth, of the valve and will likely depend
upon the size and dimension of the valve, and the fluid regulated
by the valve.
[0064] The thinner outer edge interval 137A of the first valve 136
advantageously ensures that fluid or debris will easily flow past
the first valve 136 and eliminate sound or debris fragments from
escaping the drain, while the thicker outer edge interval 139A of
the second valve 138 ensures that the second valve 138 will remain
sealed even if there is backflow, back pressure, or debris
fragments projected from downstream of the second valve 138.
[0065] Each of the valves 136 and 138 can have a circular
horizontal cross-section that includes a center portion configured
to be anchored to a stem 130. In this manner, ribs are not needed
to anchor the valves 136 and 138, which ensures that solids such as
food debris are less likely to clog the device 100. In optional
embodiments, the device 100 can further include a cap (not shown)
coupled to the stem 130.
[0066] The second valve 138 can be disposed downstream of the first
valve 136, and is preferably separated from the first valve 136 by
a distance of less than six inches, more preferably less than three
inches, and more preferably, less than one inch. All commercially
suitable configurations are contemplated for the first and second
valves 136 and 138, and preferably, the valves 136 and 138 are
biased to be convex in the upstream direction.
[0067] FIG. 2 illustrates an embodiment of a valve device 200
attached to a disposal device 228. In this embodiment of the
inventive subject matter, valve device 200 fluidly connects
directly to disposal device 228 rather than, as depicted in FIG.
10, the valve device connecting to a sink drain. In this
embodiment, the volume of sound from operating disposal device 228
is reduced as perceived by a user, and the ejection of debris
fragments from within disposal device 228 is prevented. With
respect to the remaining numerals in FIG. 2, the same
considerations for like components with like numerals of FIGS. 1A-C
apply.
[0068] In FIG. 3, an embodiment of a device 300 is shown that is
disposed within a cartridge 302. The cartridge 302 can include a
housing 304 that comprises inner and outer portions 310 and 311,
respectively, although it is contemplated that the housing 304 can
comprise a single piece.
[0069] Preferably, the device 300 is configured to be
user-removable from the housing 304, to provide easy access to
device 300 and the drain for maintenance or other needs. In this
manner, a user can easily access a drainpipe downstream of the
device 300 by removing the device 300. This allows for a plumber's
snake or other tool to be ran through the cartridge 302 without
requiring removal of the cartridge 302 itself. It is contemplated
that each of the housing 304 and device 300 can be composed of any
commercially suitable material(s) including, for example, plastics
and other polycarbonates, metal, quartz, porcelain, and any
combination(s) thereof.
[0070] Cartridge 302 is preferably sized and dimensioned to fit
within a drain recess, including, for example, drains found in
tanks, vats, floor drains, and sinks. Although cartridge 302
preferably has a horizontal cross-section that is cylindrical in
shape, the shape of cartridge 302 can be varied to correspond to
the drain's shape. Alternatively, an adapter (not shown) can be
used to adapt the cartridge 302 to the drain's size and dimension.
The top 312 of cartridge 302 can include a downward slope to
facilitate fluid and debris flow to openings 322.
[0071] Device 300 can include threads 309 that are configured to
engage with threads 307 disposed on the inner portion 310 of
housing 304. In this manner, device 300 can be removably threaded
and thereby secured or removed from, housing 304. However, other
commercially suitable fasteners could be substituted for threads
307 and 309 such that the device 300 can be removably inserted
within housing 304. To ensure an effective seal is maintained
between the housing 304 and device 300, one or more o-rings or
other commercially suitable flexible seals can be disposed about
device 300. Alternatively, such flexible seal could be coupled to
housing 304.
[0072] Device 300 preferably includes valves 336 and 338 to provide
additional protection against the escape of sound from a grinding
device. Preferred valves comprise gravity flow valves that are
biased closed such that the valves 336 and 338 are closed when not
in use. Each of valves 336 and 338 can comprise a skirt valve,
although other commercially suitable gravity flow valves could
alternatively be used including, for example, umbrella valves, duck
bill valves, and other flexible valves. Valves 336 and 338 can
include a flexible, synthetic membrane that can comprise any
commercially suitable material(s) including, for example, silicon
fabric or other synthetic and/or flexible materials, or
combinations thereof, which provide protection to the valves from
significant damage or degradation by fluids, debris, and cleaning
solvents.
[0073] Each of the first and second valves can have an outer edge
interval 337A and 339A, respectively. Preferably, the average
thickness of the first outer edge interval 337A is less than the
average thickness of the second outer edge interval 339A. More
preferably, the average thickness of the first outer edge interval
337A is less than 95%, and most preferably, less than 80% of the
average thickness of the second outer edge interval 339A.
[0074] The second valve 338 can be disposed downstream of the first
valve 336. In some embodiments, a single valve suffices to embody
the inventive subject matter. In preferred embodiments, the first
and second valves 336 and 338 are separated by a distance less than
or equal to six inches, and more preferably, less than or equal to
three inches. All commercially suitable configurations are
contemplated for the first and second valves 336 and 338, and
preferably, the valves 336 and 338 are biased to be convex in the
upstream direction. Preferably, the first valve 336 has a rigidity
that is greater than a rigidity of the second valve 338.
[0075] Valves 336 and 338 are preferably disposed within device 300
rather than cartridge 302, which advantageously allows the valves
336 and 338 to be removed for cleaning or replacement without
necessitating removal of the cartridge 302 from a sink or other
drain. In this manner, an interior of the device 300 can define a
passageway configured to allow fluid and debris to flow from the
first valve 336 to the second valve 338 to the outlet 324. However,
it is also contemplated that at least one of valves 336 and 338
could be disposed elsewhere within cartridge 302. It is especially
preferred that the valves 336 and 338 can be disposed such that an
end portion of the valves 336 and 338 is each seated beneath
downwardly-sloping valve seats 394 and 396, respectively. In this
manner, any backflow or pressure beneath the valves 336 and 338
will keep the valves 336 and 338 pressed against the respective
valve seats 394 and 396, and thus the valves 336 and 338 can remain
sealed.
[0076] To prevent removal of the cartridge 302 from a drain
housing, one or more barbs 374, and preferably at least three barbs
374 can extend from the cartridge 302. In this manner, should
someone attempt to remove the cartridge 302, the barbs 374 would
dig into an inner portion of the drain housing and thereby inhibit
removal of the cartridge 302. It is contemplated that the barbs 374
could be composed of stainless steel or any other commercially
suitable material(s) such that the barbs 374 have sufficient
strength to withstand an applied force of at least 10 N and resist
removal of the cartridge 302.
[0077] In FIG. 4, a device 400 is shown into which a device 426
having first and second valves 436 and 438 can be inserted. The
valves 436 and 438 are preferably gravity flow valves, which are
each disposed about a stem 430 disposed in the device 400. In this
manner, fluid and debris can flow through openings 422 into the
device 426 and past the valves 436 and 438. The fluid and debris
can then exit the device 426 through outlet 424.
[0078] As shown in FIG. 4, the device 400 can be disposed within a
drain 440. The housing 410 of the device 400 can include an
outwardly extending portion 414 configured to maintain the position
of the housing 410 with respect to the drain 440. With respect to
the remaining numerals in each of FIG. 4, the same considerations
for like components with like numerals of FIG. 3 apply.
[0079] FIGS. 5A-5C illustrate various views of a skirt valve 500
that includes a core 520, and an elongated rim 510 that extends
outwardly from the core 520. Preferably, the rim 510 is configured
to have a downwardly-sloping surface as the rim 510 extends from
core 520. It is especially preferred that the rim 510 is sloped at
an angle of 30 degrees, although other angles could be used
depending upon the application. In some contemplated embodiments,
the core 520 and the rim 510 can be composed of a single piece,
although the core 520 and rim 510 could alternatively be separate
pieces that are coupled to create a seal therebetween. Although the
skirt valve 500 is shown to have a circular shape, all commercially
suitable shapes are contemplated including, for example, a square
shape, an ovular shape, an icosagon-shape, and a half-circle
shape.
[0080] Preferably, the rim 510 extends from the core 520 in a 360
degree manner. As shown in FIG. 5C, the rim 510 can be tapered and
include an inner portion 512 and an outer edge interval 514. In
this manner, the inner portion 512 can have a greater average
thickness than the outer edge interval 514, which gives the inner
portion 512 additional rigidity, while giving the outer edge
interval 514 greater flexibility than the inner portion 512. Thus,
unlike umbrella valves of the prior art, at least one-eighth,
preferably one-third, more preferably at least one-half, and most
preferably, at least three-fourths, of the rim 510 can remain
rigid, and provide sufficient strength such as to prevent backflow
and sound from getting upstream through the valve 500.
[0081] In an exemplary embodiment, the inner portion 512 of the rim
510 can have an average thickness of between 0.001-0.08 inches,
more preferably of between 0.001-0.04 inches, and still more
preferably of between 0.001-0.01 inches. Using the same example,
the outer edge interval 514 could have an average thickness that is
less than 95%, more preferably 90%, 85%, 80%, 75%, 70%, 65%, 60%,
55%, or 50%, of the average thickness of the inner portion 512.
However, the specific average thicknesses of the inner portion 512
and the outer edge interval 514 will depend on the size and
dimension of the skirt valve 500, and the specific application.
[0082] The core 520 can advantageously include an opening 530 such
that the core 520 can be mounted or other affixed to a stem or post
of a cartridge or other valve housing. This advantageously
eliminates the need for spokes or other means that extend above the
valve 500, which are prone to collecting debris.
[0083] Optionally, the skirt valve 500 could include one or more
ribs (such as those shown in FIGS. 8A-9B) extending from the core
520 along a portion of the rim 510 to provide additional support to
the rim 510.
[0084] In FIG. 6, a valve 600 including a rim 610 that has an
ovular horizontal cross-section, and includes an inner portion 612
and an outer edge interval 614. With respect to the remaining
numerals in FIG. 6, the same considerations for like components
with like numerals of FIGS. 5A-5C apply. FIG. 7 illustrates a valve
700 that includes a rim 710 having a semi-circular horizontal
cross-section. With respect to the remaining numerals in FIG. 7,
the same considerations for like components with like numerals of
FIGS. 5A-5C apply.
[0085] In FIGS. 8A-8B, an embodiment of a skirt valve 800 is shown
having a plurality of ribs 840 extending radially from the core 820
to provide additional support to the rim 810. Preferably, the ribs
840 are disposed on a lower (downstream) surface of the valve 800.
The addition of ribs 840 is beneficial, especially where the skirt
valve 800 has a diameter or length of three inches or greater. In
some contemplated embodiments, the ribs 840 could have a diameter
of between 0.03-0.1 inches, and more preferably, of between
0.04-0.08 inches. However, the specific thickness of the ribs 840
will depend on the diameter or length of the skirt valve 800, and
the specific application. For example, the ribs 840 might be
thicker for a skirt valve having a larger diameter, and thinner for
a skirt valve having a smaller diameter. With respect to the
remaining numerals in each of FIGS. 8A-8B, the same considerations
for like components with like numerals of FIG. 5A apply.
[0086] FIGS. 9A-9B illustrate another embodiment of a skirt valve
900 having circular ribs 940 and 942, which are configured to
strengthen a rigidity of the valve 900. Although the ribs 940 and
942 are shown having a circular shape, it is contemplated that the
shape of the ribs 940 and 942 can vary, especially depending upon
the shape of the valve 900. With respect to the remaining numerals
in each of FIGS. 9A-9B, the same considerations for like components
with like numerals of FIG. 5A apply.
[0087] The valves of FIGS. 5A through 9B are preferably comprised
of materials providing flexibility and rigidity, include rubbers,
plastics, polymers, foams, composite materials, or a combination of
dissimilar materials. It is preferred that the rigidity of the
valve decrease radially from the center of the valve out toward the
edges. Viewed from another perspective, the flexibility of the
valves increases radially from the center of the valve out toward
the edges.
[0088] In some valves of the inventive subject matter, the rigidity
of the valve varies such that the valve will flex at some portions,
thus permitting fluid or debris to pass through, and will remain
rigid at other portions. In portions that flex, it is contemplated
the valve will flex in response to a mass of at least 0.1, 0.5,
0.8, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.8, 2, 2.2, 2.4, 2.6, 2.8, 3, or
3.5 grams over a 4 mm.sup.2 area of the valve surface, while in
some embodiments the valve will flex in response to a mass of at
least 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 12, or 15
grams over a 9 mm.sup.2 area of the valve surface. In preferred
embodiments, the valve thickness will vary such that, along a
region of the valve surface within at least 2, 1.8, 1.6, 1.4, 1.2,
1, 0.8, 0.6, 0.5, 0.4, 0.3, or 0.2 inches from the outer edge of
the valve, food debris weighing at least 1, 1.5, 2, 2.5, 3, 3.5, 4,
4.5, 5, 6, 7, 8, 9, or 10 grams will depress (flex) a portion of
the valve and pass through the valve.
[0089] The surfaces of the view can have various textures. The
upper (upstream) surface and the lower (downstream) surface of the
valve can have the same texture, while in preferred embodiments the
textures will differ. It is contemplated that the upper surface may
have a smooth surface, or may have a non-stick coating or other
coating having a low coefficient of friction. The lower surface may
have irregular texturing or symmetric texturing optimized for
abstracting sound waves. It is also contemplated that the lower
surface of the valve be coated with a sound absorbing material,
such as acoustic fiberglass, acoustic foam, acoustic cotton,
acoustic fiber, acoustic polymer, or other acoustic materials
having high acoustic impedance. It is also contemplated that the
lower surface be coated with material having high acoustic
reflection coefficient. The lower surface can further be contoured
or configured such that acoustic waves originating from downstream
(e.g. a grinding chamber) are reflected toward the chamber, or at
least in a direction away from a user.
[0090] Valves of the inventive subject matter can be shaped,
coated, composed, oriented, or otherwise adapted and incorporated
into drains in order to absorb, reflect, or otherwise reduce the
decibel level of an operating grinding device as perceived by a
user. In some embodiments, the valves reduce the decibel level of
an operating grinding device, as perceived by a user, by at least
5%, 10%, 15%, or 20%, while in preferred embodiments the reduction
is at least 25%, 30%, 35%, 40%, 50%, or 60%, and in especially
preferred embodiments the reduction is by as much as 90%. In some
embodiments, the decibel level perceived by a user operating a
grinding device is according to the systems, methods, and devices
of the inventive subject matter is less than 125 dB, 100 dB, or 95
dB, more preferably less than 90 dB, 85 dB, 80 dB, 75 dB, 70 dB, 65
dB, 60 dB, 55 dB, 50 dB, 45 dB, or 40 dB, and even more preferably
less than 35 dB, 30 dB, 25 dB, 20 dB, or 15 dB.
[0091] FIG. 10 depicts a sink and drain combination 1000 comprising
sink 1010 and valve device 1030. As shown, sink 1010 includes sink
drain 1020, which provides for the draining of fluid and debris out
of the sink. Valve device 1030 is shown inserted into sink drain
1020. In some embodiments, valve device 1030 can be removed and
reinserted by a user. In some embodiments, valve device 1030 and
sink drain 1020 form a seal when valve device 1030 is inserted into
sink drain 1020. As depicted, valve device 1030 is an embodiment of
the inventive subject matter as disclosed throughout this
application. As such, sink and drain combination 1000 is capable of
draining sink 1010 of fluid or debris such that valve device 1030
is in a closed configuration after draining sink 1010, and is
capable of muffling any noise from operating a grinding device.
[0092] FIG. 11 depicts disposal system 1100, which comprises sink
1110, valve device 1130, and disposal device 1140. As shown, valve
device 1130 is fluidly connected to sink 1110 via sink drain 1120,
and is also fluidly connected to disposal device 1140. In some
embodiments, valve device 1130 is an embodiment of the inventive
subject matter as disclosed throughout this application. Disposal
system 1100 is configured such that valve device is capable of
draining fluid or debris from sink 1110 through sink drain 1120 and
into disposal device 1140. After sink 1110 is empty, valve device
1130 defaults to a closed position such that disposal device 1140
is at least partially sealed from sink 1110. Because valve device
1130 is biased to a closed position, any operating noise from
disposal device 1140 is reduced.
[0093] FIGS. 12A-12B illustrate another perspective of a valve
device for reducing the sound of a garbage disposal. Valve device
1200 comprises housing 1210, skirted valve 1220, and baffle 1250.
FIG. 12A depicts a top down view of valve device 1200, where baffle
rim 1232 is seated tightly around housing 1210. In some embodiments
housing 1210 has a diameter of less than 1 inch, but could have a
diameter ranging from 1-2 inches, 2-3 inches, 3-5 inches, or 4-6
inches. Housing 1210 comprises housing rim 1211 housing post 1214
which is supported by housing support beam 1212. Housing post 1214
is connected to and supports skirted valve 1220, which is disposed
within housing 1210. FIG. 12B shows a vertical cross-section of
valve device 1200 seated within disposal housing 1240. As depicted,
baffle 1230 comprises baffle rim 1232 and baffle ribs 1234. In this
embodiment, baffle 1230 is disposed snugly around housing 1210,
with baffle rim 1232 setting flush with a top edge of housing 1210.
It is preferred that baffle 1230 and its components be made of a
pliable, rubberized material such that a tight seal can be formed
between disposal housing 1240 and housing 1210.
[0094] In some embodiments baffle 1230 is first seated around
housing 1210. When baffle 1230 is made of a pliable material, the
baffle is stretched and pressed around housing 1210 until the
baffle is tightly seated on the housing. Housing 1210 further
comprises housing ribs 1216, which press into and secure baffle
1230 when seated around housing 1210. In preferred embodiments, a
unit comprising baffle 1230 seated around housing 1210 can be sold
as valve cartridge 1270. When baffle 1230 is made of rubberized
materials, valve cartridge 1270 can be pressed into disposal
housing 1240 in order to reduce the sound of a garbage disposal.
Baffle ribs 1234 are preferably sized and designed such that when
valve cartridge 1270 is pressed into disposal housing 1240, a
waterproof seal is formed between disposal housing 1240, baffle
1230, and housing 1240. In some embodiments, baffle ribs 1234
protrude 1 mm from baffle 1230, but can also range from 0.5 mm-1
mm, 1 mm-5 mm, 5 mm-15 mm, 10 mm-20 mm, or 15 mm-35 mm.
[0095] Skirted valve 1220 is held in position within housing 1210
via housing post 1214 and valve connector 1250. In some embodiments
skirted valve 1220 has a diameter of less than 1 inch, but could
have a diameter ranging from 1-2 inches, 2-3 inches, 3-5 inches, or
4-6 inches. Skirted valve 1220 can be sized and dimensioned such
that skirted valve 1220 has a surface area ranging from 2-6
in.sup.2, 5-15 in.sup.2, 10-20 in.sup.2, or 20-35 in.sup.2. Skirted
valve 1220 comprises valve collar 1222, which sets atop valve
connector shelf 1255 and around a portion of valve connector 1250.
Valve connector 1250 and housing post 1214 connect to each other at
threaded interface 1260, with valve connector 1250 and housing post
1214 each comprising a mated, threaded portion. When skirted valve
1220 is fastened to housing post 1214, an outer portion of skirted
valve 1220 presses against valve seat 1218 and thereby reduces the
noise of a garbage disposal.
[0096] FIG. 13 depicts valve housing 1300 comprising housing 1310,
housing ribs 1316, housing rim 1311, housing support 1312, housing
post 1314, and valve seat 1318. Housing ribs 1316 are raised edges
along the exterior circumference of housing 1310 configured to
engage with a flexible baffle, such as baffle 1600 in FIG. 16. As
depicted, housing support 1312 extends from an interior wall of
housing 1310 at an angle away from valve seat 1318 and toward
housing rim 1311. It should be appreciated that housing support
1312 can also extend in a direction perpendicular to an interior
wall of housing 1310, or at an angle away from housing rim 1311 and
toward valve seat 1318. Housing post 1314 is disposed at an end of
housing support 1312 toward the center of housing 1310.
[0097] FIG. 14 depicts an additional embodiment of the inventive
subject matter, valve housing 1400. Valve housing 1400 comprises
housing 1410, housing ribs 1416, housing rim 1411, housing supports
1412 and 1413, housing post 1414, and valve seat 1418. Elements
depicted in FIG. 14 having similar numbering (i.e. last two digits)
as FIGS. 12a-b and 13 above have the same description. As depicted,
housing support 1412 and 1413 meet at housing post 1414 and form a
180.degree. angle in a horizontal plane. It should be appreciated
that housing support 1412 and 1413 could form an angle ranging from
90.degree.-180.degree., 60.degree.-120.degree.,
70.degree.-140.degree., or 120.degree.-180.degree. in a horizontal
plane. Housing support 1412 and 1413 also meet at housing post 1414
and form a 130.degree. in a vertical plane. It should be
appreciated that housing support 1412 and 1413 could form an angle
ranging from 90.degree.-180.degree., 90.degree.-120.degree.,
70.degree.-140.degree., or 120.degree.-180.degree. in a vertical
plane.
[0098] FIG. 15 depicts valve device 1500 of the inventive subject
matter. Elements depicted in FIG. 15 having similar numbering (i.e.
last two digits) as FIGS. 12a-b, 13, and 14 above have the same
description.
[0099] FIG. 16 depicts baffle 1600, comprising baffle rim 1632,
baffle ribs 1634, baffle inner wall 1636, and baffle groves 1638.
Elements depicted in FIG. 16 having similar numbering (i.e. last
two digits) as FIGS. 12a-b and 15 above have the same description.
Baffle 1600 comprises baffle groves 1638 disposed in baffle inner
wall 1636. Baffle groves 1638 are sized and dimensioned to receive
housing ribs, such as housing ribs 1416 in FIG. 14. The seating of
housing ribs 1416 and baffle groves 1638 helps to secure baffle
1600 in place around a valve housing, such as valve housing 1400,
and helps to create a watertight seal with a valve housing.
[0100] It should be apparent to those skilled in the art that many
more modifications besides those already described are possible
without departing from the inventive concepts herein. The inventive
subject matter, therefore, is not to be restricted except in the
scope of the appended claims. Moreover, in interpreting both the
specification and the claims, all terms should be interpreted in
the broadest possible manner consistent with the context. In
particular, the terms "comprises" and "comprising" should be
interpreted as referring to elements, components, or steps in a
non-exclusive manner, indicating that the referenced elements,
components, or steps may be present, or utilized, or combined with
other elements, components, or steps that are not expressly
referenced. Where the specification claims refers to at least one
of something selected from the group consisting of A, B, C . . .
and N, the text should be interpreted as requiring only one element
from the group, not A plus N, or B plus N, etc.
