Full Description:
BACKGROUND  
       [0001]     A variety of machines in which clothes may be hung and processed in a single unit have been proposed. There are a series of patents that require the use of solvents for dry cleaning garments, for example U.S. Pat. No. 2,845,786, issued to E. L. Chrisman on Aug. 5, 1958; U.S. Pat. No. 3,166,923 issued to Zacks on Jan. 26, 1965; and U.S. Pat. No. 2,741,113, issued to Norkus on Apr. 10, 1056. The use of solvents, especially in the home, can create health and safety issues.  
         [0002]     There are additional patents that claim a machine in which the clothes are “finished” only. These patents are directed toward de-wrinkling and smoothing the clothes, typically by using steam. However, these machines do not clean the clothes, these machines are used after the clothes are already clean. Some examples of these devices are seen in U.S. Pat. No. 3,707,855 issued to Buckley on Jan. 2, 1973; U.S. Pat. No. 4,391,602 issued to Stichnoth et al. on Jul. 5, 1983; U.S. Pat. No. 3,739,496 issued to Buckly et al. on Jun. 19, 1973; U.S. Pat. No. 3,732,628 issued to Bleven et al. on May 15, 1973; and U.S. Pat. No. 4,761,305 issued to Ochiai on Aug. 2, 1988. U.S. Pat. No. 6,189,346 issued to Chen et al. on Feb. 20, 2001 discloses a clothes treating apparatus that uses a “conditioning mist” as an alternative to dry-cleaning clothes. This patent does not provide for washing clothes with water or rinsing the clothes.  
         [0003]     In addition, some patents claim machines that only dry clothes, and do not wash or finish the clothes: for example U.S. Pat. No. 3,257,739 issued to Wentz on Jun. 28, 1966; and U.S. Pat. No. 3,102,796 issued to Erickson on Sep. 3, 1963.  
         [0004]     U.S. Pat. No. 3,114,919 issued to Kenreich on Dec. 24, 1963 discloses a machine that can wash and dry using conventional laundry soap, however, this apparatus can only wash one shirt, or the like, and one pair of pants, or the like, at a time. In addition, this patent discloses an apparatus that has fixed outlets for dispensing wash and rinse water. This patent, like U.S. Pat. No. 3,664,159 issued to Mazza on May 23, 1972, utilizes a shaking of the garments to remove dirt and debris from the garments. However, shaking the garments can cause the garments to fall during the wash cycle, and can impart wrinkles to the garments. In addition, these patents teach that the wash water is applied from the top and bottom of the clothing, and not along the length of the clothing.  
         [0005]     Finally, U.S. Pat. No. 3,672,188 issued to Geschka et al. on Jun. 27, 1972 discloses an apparatus that uses conventional laundry soap water, and hot air to wash and dry clothes. However, in this patent the soap and water are applied to the garments from top and bottom nozzles. Likewise, in U.S. Pat. No. 3,868,835 issued to Todd-Reeve on Mar. 4, 1975, the water and soap are applied from nozzles located near the top and bottom of the apparatus. In neither of these apparatuses is the soap and water applied over the entire length of the garments.

     DETAILED DESCRIPTION  
       [0022]     The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced. Each embodiment described in this disclosure is provided merely as an example or illustration of the present invention, and should not necessarily be construed as preferred or advantageous over other embodiments. The detailed description includes specific details for the purpose of providing a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the present invention.  
         [0023]     In one embodiment, a single apparatus may be used to process garments. The term “process” garments means to wash, rinse, dry and/or steam garments. The apparatus may be used in residences or in hotel rooms, hospitals, laundromates, and other commercial applications. In a conventional washing machine it is best to transfer the clothes soon after they are washed to the dryer in order to prevent wrinkling. In addition, it is even better to rapidly remove dried clothes from the dryer shortly after completion of the drying process to further prevent wrinkling. When using the apparatus described herein, there is no need to rapidly move clothes from the washing machine to the dryer, or to rapidly remove clothes from the dryer. The clothes are washed and dried on hangers in the apparatus. Once the cycle is complete, the clothes may remain in the apparatus indefinitely, until ready to be worn, suspended from hangers.  
         [0024]     The apparatus may be used by placing garments on hangers, and hanging the garments on a bar within the apparatus. Plastic hangers, or any other hanger that will support the garments without imparting stains to the wet garments, may be used. A hanger alignment mechanism may also be used to secure the garments in a relatively fixed position during the operating cycle.  
         [0025]     A manifold may be used to supply water, steam and/or air to the clothes. Chemical agents for treating the garments may be injected into the water, steam and/or air stream in the manifold. The manifold may include a series of arms, with one arm on each side of the garment. The arms may contain nozzles directed downward and toward the garments. The manifold, arms, and nozzles may contain a dual internal system of pipes. One set of internal pipes allows wash water and/or rinse water to be directed toward the clothes. The other set of internal pipes allows air and/or steam to be directed toward the clothes.  
         [0026]     During operation, the wash water containing one or more chemical agents such as soap and the like may travel up the first set of internal pipes in the manifold, through the arms, out the nozzles, and onto the clothes. The entire manifold may be configured to traverse up and down the length of the hanging clothes, spraying the clothes with soapy water.  
         [0027]     After the wash cycle is complete, rinse water may travel through the same first set of internal pipes in the manifold, and arms, and out the same nozzle. The manifold may again traverse up and down the length of the hanging clothes, spraying the clothes with rinse water.  
         [0028]     In the drying cycle, air and/or steam may travel through the second set of internal pipes in the manifold, through the arms, and out a separate set of nozzles and toward the clothes. The air may be used to dry the garments and the steam may be used to remove the wrinkles from the garments. Chemical agents may be injected into the steam and/or air stream. The steam, and more particularly, the air may be recirculated through a condenser. The condenser may be used to remove the moisture from the steam and/or air stream.  
         [0029]     The sequence and duration of the wash cycle, rinse cycle, drying cycle and steam cycle may be controlled through a control panel.  
         [0030]     When the washing and drying cycle is complete, the clothes may remain in the apparatus until such time as is convenient to remove the clothes.  
         [0031]     Referring to  FIG. 1 , an apparatus  10  may include a cabinet  12  with a front wall  12   a , a rear wall  12   b , two side walls  12   c  and  12   d , and a top and bottom wall  12   e  and  12   f . The bottom wall  12   f  may include a drain  14 . In one embodiment of the apparatus  10 , the walls of cabinet  12  are insulated. The apparatus  10  may be connected to a water supply by hose  16  and an electrical supply by conductors  18 .  
         [0032]     The cabinet  12 , which may be sealed against the escape of water, may be provided with a door  22  through which clothing to be processed can be inserted. In one embodiment of the apparatus, the door  22  may be transparent so that the garments may be viewed during the operating cycle. Alternatively, the door  22  may be opaque and insulated. The door  22  may be attached to the cabinet  12  with one or more conventional hinges  6 . The door  22  may be closed and watertight during operation of the apparatus. The door  22  may, but does not have to, extend the entire length of the front wall  12   a  of the cabinet  12 .  
         [0033]     The cabinet  12  may be adjacent to a sub-cabinet  24 . The sub-cabinet  24  may include the mechanism by means of which the operating cycle of the apparatus  10  is automatically carried out. The operating cycle may include any variation or combination of pre-washing, washing, rinsing, steaming and drying. For means of illustration only, and not as a limitation, the control mechanism may allow the consumer to set the apparatus for heavy or light washing; set the water temperature; add chemical agents such as bleach, fabric softeners, or other laundry additives, set one or more rinse cycles; set an initial delay of the start of the wash cycle to allow for the action of spot-removers; set a delay of the start of the wash cycle to accommodate the convenience of the user; set a pre-wash cycle; set varying drying temperatures and times, set a steam cycle after drying to remove wrinkles from the garments, and set the apparatus for steam cycle only to quickly remove wrinkles from garments that do not require washing. The various washing and drying requirements may be set via a control panel  28 . The electricity for running the control panel  28 , and all other parts of the apparatus  10 , may be supplied through the conductor  18 .  
         [0034]     The control panel  28  may be used to effectuate the different washing and drying needs of the user. The control panel  28  may include a timer, a means for setting or programming the various washing, rinse, drying and steam cycles, as well as the temperature for each, a means for dispensing chemical agents such as laundry detergent, bleach, fabric softener, or other laundry additives, and a means for regulating the washing, rinsing, steaming and dying times.  
         [0035]     The clothes-receiving portion of the cabinet  12  may have, at its upper end, a hanging bar  30 . The hanging bar  30  may be suspended horizontally and parallel to the walls  12   a  and  12   b . The hanging bar  30  may have one or more hanger notches  32 . Hanger-mounted garments  26  such as clothes, towels, sheets or other items to be laundered may be placed on a conventional, non-rusting, hanger. The hanger may be inserted onto the hanging bar  30 , and held at regularly spaced intervals by the notches  32  in the hanger bar.  
         [0036]     Referring to  FIGS. 2A-2E , the hanger bar  30  may be configured with variable width hanger notches  32  that automatically adjust to the hanger width to align the hangers in a parallel manner. The variable width notch  32  may include a sliding notch wall  33 . An actuator  35 , or other similar device, may be used to control the width of the notch  32  by moving the sliding notch wall  33  in and out of the notch  32 . In one embodiment, the actuator  35  may include an elongated horizontal member  37  that extends the length of the hanger bar  30 . The elongated horizontal member  37  may include a number of spaced apart vertical members, one vertical member for each variable width notch. As shown in  FIGS. 2C-2E , the vertical member  39  may be coupled to the sliding notch wall  33  of its respective variable width notch  32  with a spring  41 .  
         [0037]     The elongated horizontal member  35  may be moved between an open and closed position by a solenoid (not shown) or other actuating device.  FIGS. 2C and 2D  show the elongated horizontal member  35  in the open position with the notch  32  in its widest position. In the open position, a hanger  43  may be placed in the notch  32 , or alternatively, removed from the notch  32 . With the hanger  43  in the notch  32 , the actuator  35  may be used to adjust the variable width notch  32  to secure the hanger  43 . This may be achieved by moving the elongated horizontal member  37  into the closed position as shown in  FIG. 2E . As the elongated horizontal member  37  is moved into the closed position, the vertical member  39  moves the sliding notch wall  33  inward until it engages the hanger  43  and forces it against the opposite fixed wall  45  of the notch. With the hanger  43  lodged between both the sliding side  33  and the fixed wall  45  of the notch  32 , the spring  41  will begin to compress as the actuator  35  continues to move towards the closed position. This approach allows different diameter hangers to be used in the apparatus. The variable width notch  32  will automatically adjust to the width of the hanger when the elongated horizontal member  37  of the actuator  35  is forced into the closed position.  
         [0038]     As indicated above, the elongated horizontal member  37  of the actuator  35  may be moved between the open and closed position by a solenoid (not shown) or other actuating device. In one embodiment of the hanger bar  30 , the solenoid may be user controlled by a switch (not shown). With this approach, the user can simply place the switch in one position to access the hangers and another position to secure the hangers in place for operation. Alternatively, the solenoid may be controlled automatically. By way of example, a switch (not shown) responsive to the position of the door  22  (see  FIG. 1 ) may be used. In this configuration, the notches may be opened into their widest position when the door is opened to release the hangers. When the door is closed, the variable width hanger notch may adjust to the hanger width causing parallel alignment of the hangers during operation.  
         [0039]     Referring to  FIGS. 1 and 3 A- 3 C, a manifold  40  may be used to supply water, steam and/or air to the clothes. The manifold  40  may include a plurality of arms  42 . The arms  42  may be in a single plane, parallel to each other, and perpendicular to the hanging bar  30 . The arms  42  may extend between hanger-mounted garments  26 . The first arm in the parallel plane is  42   a , and the last arm in the parallel plane is  42   z.    
         [0040]     The manifold  40  may have two sets of internal pipes. One set is the liquid-carrying pipes  46 , which may be used to transport wash and rinse water. The other set is the air-carrying pipes  47 , which may be used to transport air and steam. The liquid-carrying pipes  46  and air carrying pipes  47  may be a separate set of internal pipes inside manifold  40 . Alternatively, as shown in  FIG. 3C , the manifold  40 , liquid-carrying pipes  46 , and air carrying pipes  47  may be manufactured as a single unit with a divider  55  separating the air in the air-carrying pipes  47  from the water in the water-carrying pipes  46 .  
         [0041]      FIG. 4  is a perspective view of a water system, which may be used during the wash and rinse cycles. In the water system, water may enter the sub-cabinet  24  through the water inlet  80  attached to the water supply hose  16 . A water pump  82  may be used to pump the water through a heater  84  to the manifold  40 . A flexible pipe  86  may be used to connect a rigid pipe  85  extending from the heater  84  to the manifold  40 .  
         [0042]     A reservoir  88  may be provided for laundry detergent or other chemical agents that may be injected into the water stream, as requested by the user. A peristaltic pump  90 , or any other suitable pump, may be used to draw the chemical agents from the reservoir  88  and inject them into the water stream through a nozzle  92  penetrating the rigid pipe  85 . The peristaltic pump  90  may be disabled during the rinse cycle.  
         [0043]     In either case, once the water (with or without chemical agents) reaches the manifold  40 , it may exit the arms  42  and spray the hanger-mounted garments  26 . The manifold  40  may move up and down the length of the hanger-mounted garments  26  spraying both sides of garments  26  with the water. The water may run off the garments  26 , down to the bottom wall  12   f , through the drain  14 , and back to the water pump  82 . A waste water valve  94  may be used to recirculate the water, or discharge the water through a water outlet pipe  96 .  
         [0044]      FIG. 5  is a perspective view of an air system, which may be used during the drying and steam cycle. In the air system, air may be drawn from the cabinet  12  through an air intake port  98  by a blower  100 . The blower  100  may be a variable speed or fixed speed blower. A condenser  102  may be inserted in-line between the air intake port  98  and the blower  100 . The condenser  102  may be used to remove water from the air drawn from the cabinet  12 . The condensed water may be discharged through a water ejection tube  104 . The water ejection tube  104  may be connected to the water outlet pipe  96  in the water system.  
         [0045]     The blower  100  may be used to force the air drawn from the cabinet  12  through a heater  106  and into the manifold  40 . A flexible pipe  108  may be used to connect a rigid pipe  110  extending from the heater  106  to the manifold  40 . The rigid pipe  110  may provide a suitable location for injecting various elements into the air stream. By way of example, a steam generator  112  may be used to inject steam into the air stream through a nozzle  114  penetrating the rigid pipe  110 . A reservoir  116  may also be used as a container for chemical agents that may be injected into the air stream. A peristaltic pump  118 , or any other suitable pump, may be used to draw the chemical agents from the reservoir  116  and inject them into the air stream through a nozzle  120  also penetrating the rigid pipe  110 .  
         [0046]     Once the air stream reaches the manifold  40 , it may be directed to the hanger-mounted garments  26  through the arms  42 . The manifold  40  may move up and down the length of the hanger-mounted garments  26  blowing air or steam on both sides of garments  26 .  
         [0047]     Returning to  FIGS. 3A-3C , each arm  42  of the manifold  40  may include a plurality of liquid-exits  44  and air-exits  45 . The liquid-exits  44  and the air-exits  45  may be either nozzles or holes. Arm  42   a  may include a plurality of exits  44   a  and  45   a  on only the side facing toward the garment  26 , and arm  42   z  may include has a plurality of exits  44   z  and  45   z  on only the side facing toward garment  26 . The remainder of the arms  42  may have a plurality of exits  44  and  45  on both sides of each arm  42  so that the hanger-mounted garments  26  may be sprayed from both sides.  
         [0048]     The liquid-exits  44  and air-exits  45  may be placed on the arms  42  so that the liquid or air exits the arms  42  in a downward direction. The shape of the arms may be any shape that allows the liquid-exits  44  and air-exits  45  to point downward. By way of example, the arms  42  may have a cross-sectional shape of an isosceles triangle with the two equal sides of the triangle facing downward, and with the liquid-exits  44  and air-exits  45  on the two downward facing sides of the triangle. The downward angle of the liquid or air may be any angle necessary to prevent the garments  26  from tangling and twisting, and to help smooth the garments  26 . By way of example, a downward angle between 40 degrees and 60 degrees may be used on the liquid-exits  44  and the air-exits  45 .  
         [0049]     There are no specific requirements regarding placement of the liquid-exits  44  and air exits  45  relative to each other. That is, the liquid-exits  44  and the air-exits  45  may be placed in a horizontal line, may be placed with either on top of the other, or may be placed in any arrangement that allows liquid to exit the liquid-exits  44 , and allows air to exit air-exits  45 .  
         [0050]     Returning to  FIG. 1 , the manifold  40  may have one or more unthreaded guide holes  51 . The apparatus  10  may contain one or more guide post  50 . In one embodiment of the apparatus  10 , the number of unthreaded guide holes  51  is equal to the number to guide posts  50 . The guide post  50  may be a smooth post that runs in a vertical direction parallel to the rear wall  12   b . The guide post  50  may be inserted through the unthreaded hole  51  in the manifold  40 , and the manifold  40  may freely move along the length of the guide post  50 .  
         [0051]     The manifold  40  may have one or more threaded screw holes  53 . The apparatus  10  may contain one or more screw posts  52 . In one embodiment of the apparatus  10 , the number of threaded screw holes  53  is equal to the number of the screw posts  52 . The screw post  52  may be a threaded post that runs in a vertical direction parallel to the rear wall  12   b . The screw post  52  and the threaded screw hole  53  may be threaded so that the threaded screw post  52  will turn inside the threaded screw hole  53  and, in turning, move the manifold  40  either up or down.  
         [0052]     The screw post  52  may be moveably attached to a motor  54 . The motor  54  may be used to turn the screw post  52  in an alternating clockwise and counter-clockwise direction, thereby moving the manifold  40  up and down the screw post  52 . The motor  54  may be programmed via the control panel  28  so that the screw post  52  turns in one direction for varying lengths of time. The length of time that the screw post  52  turns in any one direction may be directly correlated to the length that the manifold  40  travels in any one direction. Thus, the screw post  52  may turn for such a length of time that the manifold  40  travels only part of the height of the cabinet  12 , or the entire length of the cabinet  12 . The control panel  28  may also provide a means for setting or programming the speed of the upward/downward motion, as well as the distance the manifold  40  travels in the upward/downward plane.  
         [0053]     In one embodiment of the apparatus, one or more racks  70  may be attached to the bottom wall  12   f . The rack  70  may extend horizontally near the bottom of the cabinet  12 . Socks or other small items may be placed on the rack  70  and treated as described above.  
         [0054]     The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
