BACKGROUND OF THE INVENTION
[0001] The present invention relates to a garment treating apparatus and more particularly
to an apparatus for cleaning, deodorizing and dewrinkling garments as a result of
being subjected to a conditioning composition in a controlled manner substantially
without the application of steam.
[0002] The prior art reflects efforts to develop garment treating systems for home use which
clean, remove wrinkles and refresh garments or clothes items which are preferably
not washed using conventional fill water immersion wash processes. The problem has
been to develop a high performing, cost effective home system for cleaning and refleshing
garments which are delicate, subject to shrinkage or require a wrinkle free appearance.
Such garments are typically cleaned using commercial laundry or dry cleaning services.
Past efforts have focused on clothes treating cabinets designed to clean and refresh
garments by employing a combination of steam and hot air which is applied to the garments.
[0003] For example, U.S. Pat. No. 3,752,373 discloses a cabinet comprising a housing of
flexible material which defines an interior region for hanging clothes. A steam generator
is mounted in the lower region of the housing to steam the clothes. A fan and heating
element are also provided in the lower portion of the housing for delivering heated
air into the interior region for drying and airing the clothes.
[0004] Another example of a clothes steaming cabinet is found in U.S. Pat. No. 5,305,484.
This patent discloses a cabinet for receiving clothes having a steam delivery means
and a hot air delivery means. The appliance includes a steaming cycle and a drying
cycle. Hangers and a bar are provided for suspending clothes items and weighted bars
are provided to tension the clothes such that wrinkles are removed.
[0005] Both of the above described systems rely primarily on steam for supplying moisture
to the clothes in an attempt to remove wrinkles and refresh the clothes items. Unfortunately,
the use of steam consumes a relatively large amount of energy in heating water and
also adds to the drying time. More importantly, steam is relatively unable to carry
finishing agents or conditioning compositions which are preferably deposited on the
garments for clearing, dewrinkling and deodorizing purposes.
[0006] U.S. Pat. No. 4,761,305 discloses a method of finishing garments by hanging them
in a sealed chamber, spraying a finishing agent which imparts refreshing ad cleaning
benefits, and thereafter or simultaneously therewith, filly applying steam to the
garments. In a final step, hot air is blown through the sealed chamber to dry the
garments. This system has the benefit of providing a means for supplying a finishing
agent to hanging clothes items but has the drawback of requiring the addition of steam
to impart the desired benefits.
[0007] Accordingly, despite numerous disclosures in the prior art, there remains a need
for a process for satisfactorily conditioning garments which is convenient for home
use. There is also a need for such a process that has improved cost and time effectiveness
in that steam applications are not required.
SUMMARY OF THE INVENTION
[0008] According to the present invention, the foregoing and other needs in the art are
attained by a clothes treating apparatus including a cabinet defining an interior
region. A rod or hook extends from a inner wall of the cabinet for supporting at least
one hanger on which a garment can be hung within the interior region. A door is movably
connected to the cabinet for closing the interior region. A fluid atomizing nozzle
is supported by the cabinet and is fluidly connected to a reservoir containing a conditioning
composition. An air compressor is connected to the nozzle for supplying air to the
nozzle such that when the air compressor is energized the conditioning composition
is drawn out of the reservoir and sprayed from the nozzle in a mist form into the
interior region. A fan is provided for circulating air within the interior region
such that the mist form of the conditioning composition is uniformly distributed onto
the garment hanging within the interior region. Accordingly, the clothes treating
apparatus provides a means for applying a conditioning composition onto garments which
does not include means for supplying steam into the interior region.
[0009] The nozzle operates to mix compressed air and the conditioning composition and spray
atomized conditioning composition into the interior region. Specifically, the nozzle
includes an air passage and a fluid passage. The reservoir is supported by the cabinet
below the nozzle and is fluidly connected to the fluid passage within the nozzle.
The air compressor is connected to the air passage of the nozzle for supplying air
to the nozzle such that an air stream flows over a fluid outlet and automatically
draws conditioning composition from the reservoir such that conditioning composition
is mixed with the air flow for forming a mist which is dispensed from the nozzle without
requiring a valve between the reservoir and nozzle.
[0010] The present invention may include an inflatable bag associated with the hanger wherein
the garment can be disposed about the inflatable bag. A blower supported by the cabinet
is provided for inflating the inflatable bag to press the garment against opposed
inner side surfaces of the interior region during or subsequent to the application
of conditioning composition to the garment. In this manner the garment may be pressed
in order to remove wrinkles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
[0012] Referring to FIG. 1, there is illustrated a clothes treating apparatus for refreshing
garments according to the present invention. As used herein, the term "refreshing"
means cleaning, dewrinkling, and/or deodorizing garments. The apparatus 10 includes
a main housing or cabinet 12. The cabinet 12 forms an interior region 14 having opposite
side walls 14a and 14b, a top wall 14c, a bottom wall 14d and a rear wall 14e. A door
16 is hingedly connected to the cabinet 12 for closing the interior region 14 formed
by the cabinet 12. The door 16 includes an inner surface 16a wherein when the door
16 is closed, the rear wall 14e of the cabinet 12 and inner surface 16a of the door
16 form opposed inner side surfaces of the interior region. A gasket 17 is provided
disposed about the periphery of the door 16 for sealing the interface between the
door 16 and cabinet 12.
[0013] Garments are hung within the interior region 14 from a rod 18 extending from the
rear wall 14e of the interior region 14. A mist of conditioning composition is sprayed
into the interior region 14 through a fluid atomizing noble 20 (FIG. 2), mounted onto
the side wall 14b. As described herein below, the present invention is configured
such that the conditioning composition is uniformly applied to the hanging garments
for refreshing the garments. As used herein, the term mist means atomized droplets
of fluid which may contain solid particles in solution with the fluid.
[0014] Effective distribution of the conditioning composition is important to achieving
the desired conditioning benefits and is enhanced by selecting a mist form of the
conditioning composition in which the mean particulate diameter size is optimally
chosen. To that end, the mean particular diameter size of the conditioning composition
mist is preferably from about 3 microns to about 50 microns, more preferably from
about 5 microns to about 30 microns, and most preferably from about 10 microns to
about 20 microns. Furthermore, it is preferable for the particular diameter size to
having narrow particle size distribution to enhance the distribution of the conditioning
composition further.
[0015] For purposes of enhancing the effective distribution of the conditioning composition
on the garments, the misting of the conditioning composition can be achieved using
any suitable spraying device such as a hydraulic nozzle, sonic nebulizer, high pressure
fog nozzle or the like to deliver target particle sizes. However, the misting is preferably
accomplished using a relatively low volume air atomization nozzle. For example, spray
nozzles commercially available from Spray Systems, Inc. (Model Nos. 850, 1050, 1250,
1450 and 1650) are suitable.
[0016] To achieve the misting of the conditioning composition within the interior region
14, a compressor 22 is provided which may preferably be supported in a upper housing
24 of the cabinet 12. The compressor 22 is connected to an air supply tube 25 which
supplies air to the nozzle 20 (FIG. 2). Alternatively, the compressor 22 may be housed
in a base of the cabinet 12 with a supply tube extending upwardly to the nozzle 20.
[0017] The conditioning composition is supplied to the nozzle 20 from a reservoir container
26 which is removably supported within a 31 cavity formed into a baffle section 27
of the side wall 14b of the cabinet. The reservoir 26 is a generally cylindrical,
bottle-like container ad is releasably connected to a fluid supply tube 28 which extends
upwardly to the nozzle 20. Accordingly, the reservoir 26 is readily filled with conditioning
composition by removing it from the side wall cavity and adding conditioning composition.
A release lever 33 may be provided which when depressed by the user causes the container
26 to be disconnected from the fluid supply tube 28 and partially ejected from the
cavity 31. During misting periods, the air compressor is operated and conditioning
composition is drawn up into the nozzle and sprayed into the interior region 14. The
reservoir may be provided with a relief valve to prevent an undesirable vacuum condition
from forming within the reservoir 26.
[0018] As shown in FIG. 2, the clothes treating 10 is configured to promote effective application
of a conditioning composition onto garments hanging within the interior region 14.
To that end, the nozzle 20 is mounted to the side wall 14b near the top of the interior
region 14 above the baffle section 27. The rod 18 is located below the top wall 14c
such that the garments hang within the interior region 14 below the nozzle 20. The
conditioning composition is sprayed, as indicated by the arrows labeled S, into the
open area of the interior region between the top wall 14c and the hanging garments,
referred to herein as a deceleration region 30. Within the unobstructed deceleration
region 30, the mist sprayed from the nozzle 20 is given an opportunity to decelerate
such that the mist is allowed to circulate gently within the interior region 14 and
uniformly distribute itself onto the hanging garments. In this regard, the deceleration
region 30 is preferably 1.736 cu. ft. (10" x 10" x 30") or more of "dead" space, such
that the spray has an adequate region to decelerate.
[0019] To provide for heating and moving air within the cabinet 12, a recirculation fan
assembly 32 is provided within the lower portion of the interior region 14. The fan
assembly 32 includes a fan 34 and a heater 36. The fan 34 is positioned to move air
within the interior region 14 in a general clockwise direction, indicated by the arrows
labeled CW. As can be seen, the movement of air within the cabinet 12 is opposed to
the spray S of conditioning composition into the interior region 14. Accordingly,
the recirculation of air acts to further decelerate the spray of conditioning composition.
[0020] Even and smooth air flow within the cabinet 12 is promoted by providing the interior
region 14 with rounded corners 38, 40 and 42. Additionally, the baffle section 27
of the side wall 14b acts to promote recirculation of air within the lower portion
of the interior region 14 below the deceleration region 30.
[0021] As discussed above, the liquid conditioning composition is dispensed into the interior
region 14 as a mist by combining it with an air stream under pressure and passing
it through the atomization nozzle 20. FIG. 3 provides a general illustration of the
configuration of the nozzle 20. As shown, the air from the compressor 22 is supplied
to an annular, conically shaped air passage 50 of the nozzle 20. Preferably, the air
provided from the compressor 22 has a pressure of from about 5 psi to about 30 psi.
Optionally, the temperature of the air supplied from the compressor 22 can be heated
to enhance distribution and deposition of the conditioning composition onto the hanging
garments. The fluid supply tube 28 of the reservoir 26 is connected to a fluid passage
52 centrally disposed within the air passage 50. Air flowing through the air passage
50 passes over an outlet orifice 54 of the fluid passage 52. The flow of air past
the outlet orifice 54 creates a low pressure region that draws the liquid out of the
reservoir 26. After being drawn through the outlet orifice 54, the conditioning composition
is mixed with air and sprayed out though a nozzle outlet 56.
[0022] While not intending to be bound by theory, it is believed that the conditioning composition
comes from the orifice 54 in fine strands. The surface tension of the conditioning
composition and the shearing forces from impact with the nozzle outlet 56 break up
the fine strands into smaller droplets. These droplets are carried away from the nozzle
20 by their initial momentum and the flow of air exiting the nozzle outlet 56.
[0023] A controller 57 and control panel 59 (FIG. 2) is provided for operating the compressor
22 and fan assembly 32 in accordance with the cycle selected by the user of the clothes
treating apparatus 10. The control panel may include a cycle selection knob 61 allowing
the user to select a cycle that matches the type of clothes to be treated such as
cotton, wool or delicate. The process for refreshing the garments hung within the
apparatus 10 preferably includes a first period of applying the conditioning composition
in a mist form onto the garments. The time for applying the conditioning composition
may be between 10 and 30 minutes depending on the choice of cycle and the load size.
While the conditioning composition is being supplied into the interior region 14,
the fan 34 is energized to circulate air within the cabinet 12. Optionally, the heater
36 may be periodically energized for supplying heat to the distributed conditioning
composition.
[0024] Following the application of the condition composition, the heater 36 and fan 34
are energized such that warm air is recirculated over the garments hanging within
the cabinet and the conditioning composition applied to the garments is dried. Preferably,
the temperature of air during the drying period is in the range from 40°C to about
80°C, more preferably from about 50°C to about 65°C. The drying time period may be
from 10 to 180 minutes long, depending on the cycle selected and load size. An exhaust
air duct 58, shown in FIG. 2, may be provided for allowing air to be exhausted from
the interior region 14 during the drying period. The exhaust duct 58 may be connected
with duct work such that the exhaust air is vented out of the user's home as is conventional
in dryer applications. The duct may be provided with a closing means such that the
duct can be closed during the conditioning composition application step.
[0025] The particular conditioning composition selected for use in the process can vary
widely depending upon the particular benefit desired. However, in preferable modes
of operating the conditioning composition will contain ingredients which can be effective
across a variety of garment fabrics. For example, the conditioning composition will
preferably be suitable for "dry-clean" only garments as well as pure cotton dress
shirts which typically require a significant de-wrinkling operating subsequent to
conventional laundering operations (i.e. home washings and drying cycles). By way
of example, one suitable composition which provides refreshing benefits comprises,
by weight; from about 0.001% to about 10% of a diethylene glycol; from about 0.01%
to about 10% of a beta cylcodextrin; from about 0.001% to about 5% of a surfactant;
from about 0% to about 2% of a preservative; and the balance water.
[0026] FIG. 4 illustrates an alternate embodiment of the present invention which includes,
in addition to the conditioning composition dispensing system discussed above, means
for pressing garments hanging within an apparatus 10'. To avoid unnecessary duplication,
only the clothes pressing means are discussed with regard to the apparatus 10' but
it should be kept in mind that the invention of FIG. 4 includes the elements disclosed
in FIGS. 1-3, with the exception of the rod 18. In describing the alternate embodiment,
elements which correspond to elements already described with regard to the first embodiment
are identified using similar numbers combined with an apostrophe.
[0027] The clothes treating apparatus 10' includes a cabinet 12' which defines an interior
region or enclosure 14' and further includes an upper housing 24'. The upper housing
24' supports a blower assembly 60 which is connected to an air supply duct 62. Alternatively,
the blower may be housed in the base of the cabinet. The air supply duct 62 has an
end 64 which extends through a top surface 14c' of the cabinet enclosure 14'. When
energized, the blower 60 moves air through the duct 62 and out through the end 64.
[0028] An inflatable hanger assembly 66 including a rigid hanger body 68 and an inflatable
bag 70 is supported within the cabinet interior region 14'. The hanger body 68 includes
a tubular inlet end 72 and a hanger-like hollow body portion 74 which connects to
the inflatable bag 70. The tubular inlet end 72 is configured to connect to the end
64 such that the blower 60 may blow air into the hanger assembly 66. The means by
which the tubular inlet end connects to the connection end can be any quick-connect
type system for sealingly connecting two tubular members.
[0029] The inflatable bag 70 is removably mounted to the hanger body 68. The advantage of
having a removable bag lies in both maintenance and performance of the clothes treating
apparatus. The removable mounting permits the bag to be replaced if it is somehow
damaged as well as providing ease of access while dressing the bag with a garment.
This is especially important for pullover type garments which do not have zippered
or buttoned fasteners. Also, different bag sizes and configurations may be needed
depending on the size and type of clothing being treated.
[0030] Once mounted and sealed to the hanger body 68, air supplied to the hanger body 68
inflates the inflatable bag 70. When the inflatable bag 70 is inflated and the door
16' is closed, the side walls of the bag 70 press against rear wall 14e' and the inner
surface 16a' of the door 16'. In this manner, when the bag is inflated, any shirt-like
garment placed about the inflatable bag 70 is pressed to remove wrinkles. The pressure
applied to the clothes can be designed, by appropriately sizing the blower 20, to
optimize dewrinkling clothes. In some cases (dewrinkling delicate clothes), less dewrinkling
pressure may be desired. Where less dewrinkling pressure is desired, the inflatable
bag 70 may be replaced with a perforated bag which, due to the perforations, applies
less pressure to clothes item placed about the inflatable bag. The blower 60 may also
be of a variable speed type such that variable dewrinkling pressure may be obtained
by varying the blower speed. Alternatively, a fixed speed blower can provide variable
speeds by using a flow restricter actuated either mechanically or electrically.
[0031] It can be seen, therefore, that the present invention provides a unique clothes treatment
cabinet which effectively refreshes garments by applying a conditioning composition
onto the garments without requiring the application of steam. Although the present
