Description
RELATED APPLICATIONS
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 13/376,365, filed Mar. 20, 2012, which is a
U.S. nationalization under 35 U.S.C. 371 of PCT Application No.
PCT/US2010/037291, filed Jun. 3, 2010, which claims the benefit of
U.S. Provisional Patent Application No. 61/183,688, filed Jun. 3,
2009, which are each incorporated herein by reference in their
entireties.
BACKGROUND OF THE INVENTION
[0002] Care and maintenance of clothing and other textiles has long
been a routine and often tedious chore. Washing and drying of
clothing frequently leaves clothing with wrinkles or in an
otherwise undesirable condition. It is well recognized that ironing
is time consuming. As a result, clothes are often used without
ironing. Further, it is common for business travelers to routinely
place wrinkled clothing in a closed bathroom with hot water running
in the bath or shower to remove or reduce wrinkles. Unfortunately,
such an approach leads to excessive waste of water and energy used
to heat the water. In addition, the effectiveness of this approach
in removing wrinkles can be limited by time constraints and can
depend on the particular clothing material.
SUMMARY OF THE INVENTION
[0003] In light of the problems and deficiencies note above, the
present inventor has recognized that an integrated steam treatment
system can provide effective steaming and/or other treatments of
textiles in a controlled manner. This steam treatment system can
substantially reduce wasted resources and produce an article of
clothing or textile having an improved appearance.
[0004] As such, a steam treatment system for textiles can include a
detachable hanger which is removably attachable to a steam unit.
The steam unit can include a vaporizing element which is
operatively connectable to a water source and is designed to
produce steam. A steam outlet with a shut-off valve can also be
part of the steam unit. The detachable hanger can be configured to
support an article of textile such as a shirt, suit, dress, slacks,
towel or the like. More particularly, the hanger can include a
support body enclosing a steam chamber and a steam inlet which is
removably attachable to the steam outlet of the steam unit. In this
manner the detachable hanger can be removably coupled to the steam
unit to allow steam to fill the hanger. The support body can also
include a plurality of steam vents or apertures which are oriented
to transmit steam from the steam chamber to the article of textile
supported thereon.
[0005] There has thus been outlined, rather broadly, the more
important features of the invention so that the detailed
description thereof that follows may be better understood, and so

[0013] The following detailed description of exemplary embodiments
of the invention makes reference to the accompanying drawings,
which form a part hereof and in which are shown, by way of
illustration, exemplary embodiments in which the invention may be
practiced. While these exemplary embodiments are described in
sufficient detail to enable those skilled in the art to practice
the invention, it should be understood that other embodiments may
be realized and that various changes to the invention may be made
without departing from the spirit and scope of the present
invention. Thus, the following more detailed description of the
embodiments of the present invention is not intended to limit the
scope of the invention, as claimed, but is presented for purposes
of illustration only and not limitation to describe the features
and characteristics of the present invention, to set forth the best
mode of operation of the invention, and to sufficiently enable one
skilled in the art to practice the invention. Accordingly, the
scope of the present invention is to be defined solely by the
appended claims.
[0014] The following detailed description and exemplary embodiments
of the invention will be best understood by reference to the
accompanying drawings, wherein the elements and features of the
invention are designated by numerals throughout.
Definitions
[0015] In describing and claiming the present invention, the
following terminology will be used.
[0016] The singular forms "a," "an," and "the" include plural
referents unless the context clearly dictates otherwise. Thus, for
example, reference to "a steam outlet" includes reference to one or
more of such features and reference to "attaching" refers to one or
more such steps.
[0017] As used herein with respect to an identified property or
circumstance, "substantially" refers to a degree of deviation that
is sufficiently small so as to not measurably detract from the
identified property or circumstance. The exact degree of deviation
allowable may in some cases depend on the specific context.
[0018] As used herein, "adjacent" refers to the proximity of two
structures or elements. Particularly, elements that are identified
as being "adjacent" may be either abutting or connected. Such
elements may also be near or close to each other without
necessarily contacting each other. The exact degree of proximity
may in some cases depend on the specific context.
[0019] As used herein, a plurality of items, structural elements,
compositional elements, and/or materials may be presented in a
common list for convenience. However, these lists should be
construed as though each member of the list is individually
identified as a separate and unique member. Thus, no individual
member of such list should be construed as a de facto equivalent of
any other member of the same list solely based on their
presentation in a common group without indications to the
contrary.
[0020] Concentrations, amounts, and other numerical data may be
presented herein in a range format. It is to be understood that
such range format is used merely for convenience and brevity and
should be interpreted flexibly to include not only the numerical
values explicitly recited as the limits of the range, but also to
include all the individual numerical values or sub-ranges
encompassed within that range as if each numerical value and
sub-range is explicitly recited. For example, a numerical range of
about 1 to about 4.5 should be interpreted to include not only the
explicitly recited limits of 1 to about 4.5, but also to include
individual numerals such as 2, 3, 4, and sub-ranges such as 1 to 3,
2 to 4, etc. The same principle applies to ranges reciting only one
numerical value, such as "less than about 4.5," which should be
interpreted to include all of the above-recited values and ranges.
Further, such an interpretation should apply regardless of the
breadth of the range or the characteristic being described.
[0021] Any steps recited in any method or process claims may be
executed in any order and are not limited to the order presented in
the claims. Means-plus-function or step-plus-function limitations
will only be employed where for a specific claim limitation all of
the following conditions are present in that limitation: a) "means
for" or "step for" is expressly recited; and b) a corresponding
function is expressly recited. The structure, material or acts that
support the means-plus function are expressly recited in the
description herein. Accordingly, the scope of the invention should
be determined solely by the appended claims and their legal
equivalents, rather than by the descriptions and examples given
herein.
Steam Treatment Systems
[0022] A steam treatment system 10 for textiles can include a steam
unit 12 and a detachable hanger 14 as shown in FIG. 1A. Each
element of the system will be described in more detail below.
However, generally the steam unit can include a vaporizing element
16 operatively connectable to a water source 18 to produce steam. A
steam outlet 20 can be adjacent to or remote from the vaporizing
element. The steam outlet can also include a shut-off valve 22 to
prevent steam escape when the detachable hanger 14 is not engaged
with the steam outlet.
[0023] The detachable hanger 14 can be configured to support an
article of textile. Thus, various shapes can be used to support
different types of clothing or other textiles, e.g. shirts, slacks,
dresses, suits, towels, and the like. Generally, the detachable
hanger can include a support body enclosing a steam chamber 24. A
steam inlet 26 can be oriented on the hanger at a point of
attachment to the hanger connection 44 of the steam unit. In one
aspect, the steam inlet can be oriented on a hook member 28 and
oriented downward to engage with the steam outlet. The hook member
can extend from the support body in a standard conventional wire
hanger hook fashion. The steam inlet can also be oriented within an
upper-most point of an inner surface of the hooked support such
that the steam inlet is oriented facing downward. In this
configuration, the weight of the hanger (and textile) can aid in
securing a connection between the steam outlet and the steam inlet.
The steam inlet can alternatively be oriented in other directions
as long as a secure connection is provided. For example, the steam
inlet can be configured such that the hanger is engaged with the
steam outlet via a substantially vertical motion downward. The
hanger connection and steam inlet of the hanger can alternatively
be provided as a horizontal slide connection (i.e. an L-shape
support which engages with a complimentary port on the hanger
connection). Optional guide contours or walls can be integrated
into the connection system to allow for mechanical positioning and
for sealing the steam connection. For example, a male and female
guide contours can ensure that a steam seal is formed and avoid
misplaced hangers, or searching for the connection.
[0024] Regardless of the specific orientation, the steam inlet can
be configured to be removably attachable to the steam outlet.
Although not required, it can be desirable to configure the
engagement design such that the act of engaging the hanger
substantially completes the fluid connections which are triggered
by the weight of the hanger. A number of connector designs can be
suitable. In one aspect, the connector can be a quick-connect.
Non-limiting examples of suitable connectors can include a poppet
style quick-connect, a drybreak quick-connect, a gravity weighted
solenoid and the like. In another aspect, one or both of the steam
inlet and steam outlet can include a magnetic member to assist in
guiding and securing the connection. In one detailed aspect, the
connector can be a magnetic seal such that no other sleeves or
mechanism is required. In this case, the magnetic seal acts as a
magnetic guide with sufficient weight and magnetic strength to
maintain a steam seal. Such embodiments can optionally include an
enclosure to spatially guide the magnetic seal counterparts and may
include a rubber seal to reduce or eliminate steam leakage.
[0025] Although the detachable hanger can have fixed dimensions,
providing adjustable dimensions for shoulders, width and/or length
can increase the versatility of the hanger for different garments.
Consistent with this concept, in one aspect, the support body can
optionally include a pair of shoulder supports configured to
support shoulders of the shouldered garment. More particularly, the
pair of shoulder supports can be positionable for adjustable
shoulder width. Adjustability can be accomplished by any suitable
mechanism. For example, the shoulder portions can be telescoping,
folding or can include detachable segments. Similarly, the steam
chamber can optionally further includes a length adjustment
mechanism configured to extend a length of the support body and
steam chamber. In this way, the mechanism can allow a user to
length-wise adjust positioning of at least a portion of the steam
vents. This can be important for garments such as a dress where it
may be desirable to direct or distribute steam over a significantly
longer distance than, for example a dress shirt.
[0026] In order to offer direct steaming or treatment to all
segment of the clothing, additional members can be provided to
direct steam to targeted areas of the clothing. For example, in one
optional aspect, the support body can include a pair of tubular arm
members which are flexible and include steam apertures therein. As
a result, when the tubular arm members are inserted into arms of an
article of clothing, the steam can be directed into the arms to
provide a thorough steam treatment throughout the sleeve
lengths.
[0027] Further, the support body can include a plurality of steam
vents 30 oriented to transmit steam from the steam chamber 24 to
the article of textile. The steam vents can typically be apertures
distributed throughout the support body and/or in selected regions.
In one aspect, the support body can be substantially hollow and
include a single cavity to form the steam chamber. However, a
plurality of steam channels 33 can be optionally included to direct
steam to different zones of the steam chamber. For example, a steam
manifold or divider can be integrated adjacent to or near the steam
inlet to produce multiple steam lines. Each steam line can
selectively direct a portion of the steam to different areas of the
support body, e.g. lower regions, side regions, arms, center,
etc.
[0028] Within the support body and steam chamber, steam or other
fluids may condense and accumulate within the chamber. Thus, an
excess fluid outlet can be integrated into the steam chamber to
allow removal of the excess fluid from the chamber. This can help
to prevent clogging and/or pressure buildup. In one aspect, the
support body can includes a vacuum line having a suction end
oriented in a lower region of the steam chamber to collect and
remove condensed water and/or excess steam vapor from the steam
chamber. The vacuum line can be oriented through a common connector
as the steam inlet or through a separately attached line (not
shown). Alternatively, a gravity drain outlet can be oriented in
the bottom of the steam chamber to allow excess liquid to be
removed.
[0029] The steam unit can have an enclosure which is configured for
a particular functional and/or aesthetic application. Various
configurations can allow the system to be attached to a shelf,
door, divider wall, embedded in a wall, or suspended between two
walls, to name a few options. In one alternative, the steam unit
can be shaped to slide over a planar fixture such as a shelf, a
door, and a divider wall. When designed for shelf-mounting, the
shelf can be a fixed wall-mounted shelf, a cabinet shelf, a
wardrobe shelf, or the like. This general shape for mounting on
shelves or other planar fixtures can be a U-shape such as that
shown in FIG. 1A. In this configuration, the steam unit includes an
upper member 32 coupled to a lower member 34 via a front bridge
member 36 such that a gap 38 is formed between the upper member and
the lower member such that the steam unit is configured to slide
onto the planar fixture 40. In this manner, the steam unit can be
readily installed onto existing shelves with minimal, if any,
modifications to the existing shelves. Although FIG. 1A illustrates
a horizontal fixture, vertical or inclined fixtures can also be
used. For example, a divider wall can provide support. The steam
unit and hanger attachment points can be adjusted accordingly to
allow the hangers to hang with sufficient clearance from the wall
or other structures.
[0030] Although many shelves have a similar width, there are
variations in widths such that achieving a secure interface with
the shelf is desirable. As such, a securing mechanism can be used
to affix the steam unit to the planar fixture. In one aspect, the
securing mechanism can be a gap adjustment mechanism. In this case,
the front bridge member can include the gap adjustment mechanism
configured to allow variable adjustment of a width of the gap. Thus
the front bridge member can be adjustable to allow for varying gap
distances. The front bridge member can include sliding walls,
accordion walls, or the like. In some designs, the steam,
electrical connections, secondary fluids, or other system lines can
pass through the front bridge member. Therefore, accommodation for
movement can be made to allow such connections to expand or move
with the gap adjustment. Although other designs can be suitable,
examples of the gap adjustment mechanism for such connections can
include a toggle joint, a flexible hose joint, or a telescoping
joint. Multiple independent steam lines, electrical lines, and/or
fluid lines can be passed through such gap adjustment mechanisms or
in the front bridge member. FIG. 1A illustrates an example of a
toggle joint 41 where three rotating joints are oriented to allow
vertical movement relative to the upper and lower joints such that
the upper member 32 can be displaced from the lower member 34 to
adjust the gap width while maintaining the steam line connection.
Each of the upper and lower members can optionally include friction
surfaces and/or securing mechanism which secure the steam unit to
the planar fixture. Friction surfaces can include, but are not
limited to, rubber, PDMS, adhesive, and the like, while the
securing mechanisms can include tabs or holes into which screws can
be driven into the planar fixture.
[0031] In one set of embodiments, the steam unit can include a
hanger support member which is configured to mechanically support
the detachable hanger(s). In one aspect, the steam unit can further
include a steam chambered rod 42 including the steam outlet 44. In
this embodiment, the chambered rod is fluidly connected to the
water source to allow the steam to flow into the chambered rod. The
rod can optionally be sized to accommodate standard clothing
hangers, e.g. a diameter from about 3/4 inch to about 2 inches. The
rod can optionally include spacing grooves or other contours. In
such a case, there can be one or more steam outlets 44 oriented
along the rod length and either grouped in one region of the rod or
spaced such that detachable hangers and conventional hangers can be
intermingled.
[0032] In one alternative, the steam unit is shaped to slide into a
cut-out area of a shelf. In this case, a main body of the steam
unit can include multiple flanges or a continuous recessed outer
flange area such that the main body fits into the cut-out area and
the flanges rest on the shelf along edges of the cut-out area.
[0033] In another alternative embodiment, the steam treatment
system can be configured as a rod. For example, the rod can be
configured to mount in opposing side walls of a closet at opposing
ends of the rod. The rod can include a water or steam inlet and the
steam outlets as described previously. As such, the vaporizing
element can be integrated into the rod. In this case, the rod can
include a water inlet and the steam is produced internally within
the rod. Optionally, the steam can be produced separately such as
by a steam boiler which is oriented nearby having a steam line
which is fluidly connected to the rod. Such a boiler can be placed
on the shelf above the rod, on the floor, or in a separate
centralized location. In one aspect, a common steam boiler can be
connected to multiple rod-hanger systems throughout a home or
building, e.g. a hotel. Such a configuration may be particularly
useful for a hotel where dozens of such steam treatment systems in
various rooms can be fluidly connected to a common steam boiler.
Alternatively, the steam boiler can be removably detachable from
the steam outlet such that the steam unit is configured for use as
a hand-held steam cleaner. Such a design can add functionality to
the system by allowing the steam boiler to be used to steam clean
draperies, upholstery, carpets, and the like. Optional attachments
can be used as are commonly known used for hand-held steam
cleaners.
[0034] In one aspect, the rod can include a steam-sealed length
adjustment mechanism configured to allow adjustment of the rod
length. Thus, the rod length can be customized to fit a variety of
closet sizes or other placements. The length adjustment mechanism
can be any which allow for changing the rod length while also
maintaining a steam seal. In one aspect, this can include providing
isolated flexible channels within the rod body which extend with
the rod. The flexible channels can be directly and individually
connected to the steam outlet or outlets. Alternatively, the
steam-sealed length adjustment can be a threaded joint between at
least two rod segments, a compression washer oriented between two
rod segments, a detent, threaded clutch, split collar lock, snap
collar lock, internal cam lock, or set screw. In another aspect,
the rod can be resiliently flexible to allow extension and
contraction of the length. In yet another aspect, the adjustable
rod can have a non-adjustable portion that produces steam and at
least one other portion that does not produce steam.
[0035] For example, as illustrated in FIG. 1B, a steam unit 100 can
include a vaporizing element 102 operatively connectable to a water
source 104 to produce steam. The system can also include a steam
outlet fluidly connected to receive steam produced by the
vaporizing element 102 and direct the steam into a steam
distribution chamber 108. The steam outlet may include a shut-off
valve 106 to control flow of steam into the steam distribution
chamber through a corresponding water inlet. The steam distribution
chamber 108 can have multiple steam outlets 110. The steam outlets
110 are each removably connectable to corresponding hangers as
described further herein.
[0036] In this example, the steam unit 100 is a rod configured to
mount in opposing side walls of a closet at opposing ends (112 and
114) of the rod. The length adjustment mechanism can generally be
such that the rod is adjustable in length without loss of steam
seal. As illustrated, the rod can include two portions which
telescope with respect to one another. The telescoping portions can
be fixed in position to adjust the length of the rod to fit varying
size closets and locations. In one example, the length adjustment
mechanism can be a threaded joint between the at least two rod
segments. Alternatively, the length adjustment mechanism can be a
compression washer oriented between the at least two rod segments.
The compression washer is then engaged upon rotating each of the
segments with respect to one another to fix the rod length and
optionally engage a steam seal. FIG. 1B illustrates an example
having a segment 116 with an engagement spring 118 biasing the two
segments apart.
[0037] In one alternative, the vaporizing element 102 can be
oriented within the rod (e.g. within the steam distribution chamber
108). In this way, the steam distribution chamber can be directly
filled with water manually via a corresponding fill opening, or via
a water source line. This can reduce an overall system footprint.
In another alternative, the steam unit 100 can include flexible
steam channels within the steam distribution chamber 108 to direct
the steam to each of the steam outlets 110.
[0038] In still another example, the system can also include at
least one detachable hanger configured to support an article of
textile. The hanger can include a support body enclosing a steam
chamber and a steam inlet removably attachable to the steam outlet.
The support body can include a plurality of steam vents oriented to
transmit steam from the steam chamber to the article of textile as
described previously herein.
[0039] In yet another aspect, the steam unit can be configured to
collapse in a non-working state to slide underneath a bed, e.g.
typically having a clearance of less than 10 inches. In such
embodiments the enclosure and any extending members can be
configured to have a low profile for convenient storage.
[0040] The steam treatment system including a water source 50,
steam unit 52, and detachable hanger 54 can optionally be mounted
on an inner panel of a door 56 or wall as shown in FIG. 2. This can
be accomplished by drilling, adhesive or other means directly on
the door surface. Alternatively, the steam unit can be configured
to be embedded in a door or wall. Such an installation can reduce
space occupied by the system and also allow for a custom
appearance. Water inlets can be optionally integrated into the door
via suitable flexible connectors. In yet another alternative, the
steam unit can be configured as a stand-alone steam dresser as
shown in FIG. 3. Although clothing can be readily steam treated
using the systems of the present invention other textiles such as
towels, sheets, tablecloths, and the like can also be treated. FIG.
4 illustrates a towel system where the detachable hanger is a rod
58 over which the towel 60 can be draped. Alternatively, the
detachable hanger can be configured as a panel such that the entire
length of the towel is exposed to steam treatment. Such detachable
hangers can also be suitable for clothing such as slacks, vests,
robes, and the like.
[0041] In each of the described embodiments of the steam treatment
system, the following additional aspects can also be used. The
water source can be integrated into the system such that the system
can act as a stand-alone device. More particularly, the water
source can be a refillable tank having a fill inlet. In this case,
the water source can be manually refilled as needed. Alternatively,
the water source can be a fixed water supply line, e.g. a public
water supply, to which the system can be connected. As previously
discussed, the steam generator or vaporizing element can be placed
in the tank or can be fluidly connected to the tank via an outlet
water line. For example, the water source can be a water supply
line and the vaporizing element can be connected to the water
supply line via a water-line connector. Alternatively, the
vaporizing element is housed in an external boiler configured to
produce the steam. This steam unit can further include a steam line
fluidly connected to the external boiler to the steam outlet.
[0042] Optionally, additional optional convenience features can be
incorporated into the design. In one basic aspect, the system can
include a single detachable hanger. However, multiple detachable
hangers 70 and complimentary steam outlets 72 can be provided as
shown in FIG. 5. The steam outlets can be operated along a common
fluid/steam delivery such that the same fluid treatment occurs for
each article of textile. However, in many cases customized
treatment cycles can be desired. In such cases, each hanger-steam
outlet combination can have an independently controllable treatment
cycle. Such cycles can be as simple as a manual on-off switch or
can include customizable multi-fluid cycles as described in more
detail below. Regardless, the steam unit can include multiple steam
outlets which each include a corresponding shut-off valve. The
multiple outlets can each have a dedicated steam line from the
vaporizing element or steam source.
[0043] In one aspect, the system can include a cycle control unit
configured to selectively control flow of steam through the steam
outlet. This cycle control unit can be applied to single or
multiple hanger designs. The cycle control unit can be configured
to control a variety of variables such as steam delivery times,
number of repeat cycles, additional secondary fluid treatments, and
the like. FIG. 5 illustrates optional indicators 74 which show the
current status of each hanger cycle, water fill levels, and/or
other system status information. This system can also control steam
flow for safety purposes. For example, the system can be
operatively connected to the shut-off valves at each steam
connection. A locking mechanism can also be integrated into the
connector in order to prevent removal of the hanger when the
connection is steam pressurized. This can be beneficial to prevent
accidental removal of the hanger during a steam or cleaning cycle.
The locking mechanism can be a lock pin, detent, or other suitable
lock system that prevents removal of the hanger from the steam
outlet when steam is present. The lock system can alternatively
include a manual override. In another option, the lock system can
include a one-way valve within the steam hanger which allows steam
to enter but not to escape from the same route. The steam unit can
then be equipped with either a mechanical lock system and/or a
software protocol which shuts down steam flow when internal
pressure drops below a threshold value (i.e. indicating a leak in
the system).
[0044] In one specific aspect, the system can include at least one
secondary fluid line fluidly coupled to the steam outlet configured
to deliver a secondary fluid to the shut-off valve. The secondary
fluid line can also be connected to a secondary fluid reservoir.
The secondary fluid can be at least one of a fragrance, a cleaning
agent, a fabric softener, dry air, and a spot remover. In order to
selectively control when the secondary fluid(s) is delivered, the
secondary fluid line can be coupled to the steam outlet via a
secondary fluid valve which is responsive to the cycle control
unit. Similarly, a supplemental fluid can be mixed with the water
source or introduced into the steam. Non-limiting examples of
supplemental fluids can include carbon dioxide, fragrance, and
fabric softener.
[0045] The system can further include a garment detection mechanism
configured to correlate the article of textile with the treatment
cycle. In this manner, a customized treatment cycle can be applied
to a particular garment based on a predetermined cycle. Such
customized cycles can be affected by the type of material (e.g.
wool, silk, cotton, etc.), weight or thickness of the material,
size of the garment, weave density, and the like. Such customized
cycles can be stored in the cycle control unit or programmed by the
user.
[0046] In one aspect, the garment detection mechanism can includes
an RFID tag located on either the article of textile or the
detachable hanger. An RFID receiver can be electrically coupled to
the cycle control unit which is configured to recognize the RFID
tag upon engagement of the detachable hanger with the steam unit.
Thus, the steam unit can also act as a base module and a steam
control center.
[0047] The cycle control unit can be pre-programmed, user
programmed and/or updatable via a suitable input source.
Accordingly, the cycle control unit can be electrically coupled to
a data communication link unit configured to receive customized
cycle data for corresponding garments. Although other data
communication link units can be used, non-limiting examples include
at least one of a USB port, a wireless card, an Ethernet adapter, a
memory card slot, and a set of manual user controls. In one
specific aspect, the data communication link unit can include an
Internet connectivity unit configured to receive cycle instructions
remotely from a user which include at least start of a steam cycle
for a designated hanger unit.
[0048] Each portion of the steam treatment system can be formed of
suitable materials based on corrosion resistance, mechanical
strength and performance. For example, polymers used which are in
contact with the steam will generally have an operating temperature
tolerance of at least 120.degree. F., and in some cases up to about
320.degree. F.
[0049] An additional aspect of the steam treatment system can
include safety features which prevent unintentional contact with
steam, leakage, and/or system damage. In one aspect, the shut-off
valve can be manually actuated. However, a safety shut-off unit can
be configured to terminate delivery of steam to the detachable
hanger upon a trigger event. The safety shut-off unit can be
coupled to the shut-off valve and configured to close the shut-off
valve. This can be any suitable device such as but not limited to a
solenoid. In another aspect, the safety shut-off unit can be
coupled to the steam unit and configured to terminate power to the
vaporizing element. The trigger event can be at least one of
mechanical pressure on the detachable hanger, opening of a closet
door, and exceeding a critical temperature within the steam
chamber. For example, a child pulling on the detachable hanger can
indicate an undesirable risk. Similarly, a vaporizing element
shut-off can be coupled to the vaporizing element and can be
configured to stop steam production upon a trigger event. Such
trigger events can include at least one of exceeding a critical
steam pressure, exceeding a critical steam temperature, and failure
of the shut-off valve. In either case, if the steam exceeds a
certain temperature or pressure this can indicate a blockage or
other malfunction.
[0050] The detachable hangers can be open and unenclosed. However,
it can often be desirable to at least partially enclose the
detachable hanger and article of clothing in order to increase
steam residence time and localize the steam around the article of
clothing. This can be accomplished by installing the system within
an enclosed structure such as a closet or wardrobe. The closet
doors can be fitted with a switch which is connected to the cycle
control unit and which can be used to pause the cycle treatment. In
still another aspect, a shroud can be configured to individually
enclose the article of textile to increase steam residence time.
Such a shroud can be sized to fit around the article of clothing.
In one optional aspect, the shroud can be configured to reversibly
retract above the detachable hanger.
[0051] Excess vapor and steam can be removed from the system or
vicinity of the article of textile using a vent system. In one
option the vent system can be oriented within the steam source and
includes a vent outlet. The vent outlet duct can optionally include
a filter or condenser. The vent outlet can optionally be powered,
e.g. using a fan, to force steam/vapor from the system. The powered
vent can be configured to exhaust to an adjacent area. The exhaust
can be directed to outside environment or can be directed to
another area such as a room or attic space. In one aspect, the
exhaust can be directed to a room for use as a humidifying unit. In
order to add convenience in installation, the vent system can
include an adjustable vent configured with a telescoping
length.
[0052] Depending on the water source, additional water softening
may be desirable. Therefore, in one aspect, the steam treatment
system can further include a water softener unit. The water
softener unit can be oriented upstream of the water inlet or
integrated with the steam unit.
[0053] In one aspect, at least one undermount light can be mounted
on the system and directed toward the detachable hanger so as to
illuminate the article of clothing.
[0054] In another optional aspect, the steam treatment system can
include adjustable panels configured to extend various walls of the
system to fill a particular installation area. For example, in one
aspect, width adjustment panels can be configured to extend from
ends of the steam unit to extend the width of the steam unit to
substantially correspond to a width of the planar fixture. In the
case of a shelf, the expanded system has the appearance of filling
the entire shelf width. Additionally, such panels can provide
supplemental storage space, storage compartments, and/or raised
edges which keep objects contained therein.
[0055] Specific aspects described herein with reference to a
particular embodiment can, in most cases, be applied to other
described embodiments. For example, the undermount lights described
for the planar fixture can also be applied to the stand-alone rod,
dresser style, or other embodiments. Similar interchangeability for
other detailed aspects can be made among various embodiments.
[0056] The foregoing detailed description describes the invention
with reference to specific exemplary embodiments. However, it will
be appreciated that various modifications and changes can be made
without departing from the scope of the present invention as set
forth in the appended claims. The detailed description and
accompanying drawings are to be regarded as merely illustrative,
rather than as restrictive, and all such modifications or changes,
if any, are intended to fall within the scope of the present
invention as described and set forth herein.
