Description:
[0001]     This application claims the benefit of Korean Patent Application No.P2004-99158 filed on Nov. 30, 2004 which is hereby incorporated by reference as if fully set forth herein.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a drying apparatus, and more particularly, to a composite washing system which is capable of continuously circulating laundry-drying air through dryers while obtaining a more efficient drying effect, so that the composite washing system has a suitable built-in structure.  
         [0004]     2. Discussion of the Related Art  
         [0005]     Generally, laundry dryers are adapted to dry laundry such as clothes. Such a laundry dryer receives completely-washed laundry, and then performs an operation to dry the laundry while continuously supplying hot air.  
         [0006]      FIG. 1  illustrates a general drum dryer as an example of a conventional laundry dryer.  
         [0007]     As shown in  FIG. 1 , the conventional drum dryer mainly includes a body  10 , a drying drum  20 , a door  40 , a motor  50 , a drying heater  60 , and a blowing fan  70 .  
         [0008]     The body  10  defines an appearance of the drum dryer. The drying drum  20  is rotatably disposed in the body  10 . A laundry inlet  11  is formed through the front of the body  10 . The door  40  is mounted to the front of the body  10  to open and close the laundry inlet  11 .  
         [0009]     The motor  50  is fixedly mounted on the bottom of the body  10  inside the body  10 . The motor  50  generates a drive force to rotate the drying drum  20  and the blowing fan  70 .  
         [0010]     The drying heater  60  is arranged in a hot air supply path  91  in order to heat air flowing through the hot air supply path  91 . The hot air supply path  91  guides a flow of hot air supplied into the drying drum  20 .  
         [0011]     The blowing fan  70  operates to outwardly discharge the hot air, namely, drying air, flowing through the interior of the drying drum  10 . The blowing fan  70  communicates with a hot air discharge path  92 .  
         [0012]     In accordance with the above-mentioned configuration, when the blowing fan  70  operates, air around the laundry dryer, namely, ambient air, is introduced into the body  10 , is heated while passing through the drying heater  60 , and is then introduced into the drying drum  20  while being guided by the hot air supply path  91 .  
         [0013]     Accordingly, wet laundry received in the drying drum  20  is gradually dried by the hot air.  
         [0014]     The air used to dry the laundry while passing through the drying drum  10  is outwardly discharged while being guided by the hot air discharge path  92 .  
         [0015]     When the laundry is completely dried in accordance with repeated execution of the above-mentioned procedure, the operations of the blowing fan  70  and drying heater  60  are stopped to complete the drying cycle.  
         [0016]     In the conventional drum dryer, however, there is a problem in that laundry is inefficiently dried because the drying cycle is carried out while the laundry is in an entangled state.  
         [0017]     Furthermore, there is a problem in that the laundry cannot be maintained in the dryer.  
         [0018]     To this end, a demand for a new laundry dryer has recently been made which has an increased drying capacity and enables storage of dried laundry for a prolonged period of time. To satisfy this demand, a combination type dryer has been developed, as disclosed in U.S. Published Patent Application Nos. 2004/0194339 A1 and 2004/0154194 A1. Such a combination type dryer includes a separate drying cabinet, in addition to a drum dryer, namely, a tumble dryer.  
         [0019]     In such a combination type dryer, a drying cabinet, which has a drying compartment for various clothes, is mounted on the top of a general drum dryer having a rotatable drum such that hot air is supplied to the drying cabinet.  
         [0020]     The drying cabinet receives hot air supplied from the drum dryer to dry clothes received in the drying cabinet. The drying cabinet may also be used to store the dried clothes for a prolonged period of time.  
         [0021]     However, the above-mentioned combination type dryer has a problem in that it cannot be of a built-in type because it has an air discharge type structure in which the air used to dry laundry is outwardly discharged from the dryer.  
         [0022]     In other words, where the combination type dryer is built in a wall, it is necessary to provide a sufficient built-in space to provide a sufficient gap from the surface of the wall such that air is adequately discharged away from the dryer. For this reason, the appearance of the dryer is unattractive.  
         [0023]     Furthermore, the air discharged from the combination type dryer is hot and humid, thereby causing the indoor environment to be an environment undesirable for the user, namely, a high-temperature and humid environment.  
         [0024]     In addition, in order to receive laundry having a long length, such as trousers, in the laundry compartment of the drying cabinet in the conventional combination type dryer, the laundry compartment of the drying cabinet is connected with a part of the space defined in the drum dryer. For this reason, there is a problem in that the drum, which is disposed in the drum dryer, must be of a limited size.

         [0077]     The body  210  defines an appearance of the cabinet dryer  200 , and is open at the front thereof.  
         [0078]     The laundry support  220  is mounted in the body  210 . The laundry support  220  may include a plurality of shelves  221 , and a hanger bar  222 .  
         [0079]     Each shelf is detachably mounted in the body  210 . The hanger bar  222  is detachably mounted to the body  210  in an upper space of the body  210 .  
         [0080]     The opening/closing door  230  is mounted to the front of the body  210  to open/close the open front of the body  210 .  
         [0081]     The hot air inlet duct  241  has one end connected to the second air supply duct  122  of the drum dryer  100 , and the other end communicating with the interior of the body  210 . Accordingly, the hot air inlet duct  241  receives hot air from the second air supply duct  122 , and guides the received hot air into the body  210 .  
         [0082]     Preferably, a valve  125  is arranged in the second air supply duct  122  to guide the air flowing through the second air supply duct  122  toward the first air supply duct  121  and/or the hot air inlet duct  241 .  
         [0083]     The air outlet duct  242  has one end communicating with the body  210 , and the other end connected to the third air supply duct  123  of the hot air supply path. Accordingly, the air outlet duct  242  functions to discharge hot and humid air passing through the laundry in the body  210 .  
         [0084]     A separate discharge fan (not shown) may be arranged in the air outlet duct  242 .  
         [0085]     The laundry folder according to the exemplary embodiment of the present invention is adapted to enable laundry having a long length to be received in the cabinet dryer without being wrinkled.  
         [0086]      FIG. 4  illustrates the structure of the laundry folder according to the exemplary embodiment of the present invention.  FIG. 5  illustrates a cross-sectional structure of a first guide included in the laundry folder.  FIG. 6  illustrates a cross-sectional structure of a second guide included in the laundry folder.  
         [0087]     The laundry folder will be described in detail with reference to  FIG. 4 .  
         [0088]     The laundry folder may include at least one folding rod  300  which is detachably mounted in the body  210  of the cabinet dryer  200  to fold a portion of laundry, and a folding rod guide which is provided at the body  210  of the cabinet dryer  200  to hold the folding rod  300  in a fixed state and to guide movement of the folding rod  300 .  
         [0089]     The folding rod  300  includes an elongated seat member  310 , and a position fixing member  320  which extends from one end of the seat member  310 .  
         [0090]     The seat member  310  supports a portion of laundry in a state in which the laundry portion is wrapped around or laid on the seat member  310  without being wrinkled.  
         [0091]     Preferably, the seat member  310  has a circular cross-section in order to allow laundry to be seated on the seat member  310  without being wrinkled.  
         [0092]     The position fixing member  320  functions to fix the seat member  310  at a desired position in the body  210  of the cabinet dryer  200  while allowing the seat member  310  to be movable.  
         [0093]     The position fixing member  320  also functions to prevent the seat member  310  from being unintentionally separated from the fixed position.  
         [0094]     The laundry folder may include one or more folding rods  300  in accordance with the length of the laundry to be folded by the laundry folder. Where the laundry folder includes two folding rods  300 , namely, a first folding rod  300   a  and a second folding rod  300   b , as shown in  FIG. 7 , the first folding rod  300   a  folds a portion of laundry in a state in which the laundry portion is wrapped around the first folding rod  300   a , and the second folding rod  300   b  folds another portion of the folded laundry portion in a state in which the laundry portion is laid on the second folding rod  300   b.

         [0098]     As shown in  FIG. 5 , the first guide  420  includes a first guide groove  421  which extends horizontally to allow a horizontal movement of the position fixing member  320  along the first guide  420 , and first separation preventing grooves  422  which are formed along opposite longitudinal edges of the first guide groove  421 , respectively, to prevent the position fixing member  320  from being separated from the first guide groove  421 .  
         [0099]     The second guide  430  extends vertically from the first guide  420 , and functions to guide a vertical movement, namely, an upward or downward movement, of the folding rod  300  which has been horizontally moved along the first guide  420 .  
         [0100]     As shown in  FIG. 6 , the second guide  430  includes a second guide groove  431  which extends vertically to allow a vertical movement of the position fixing member  320  along the second guide  430 , and second separation preventing grooves  432  which are formed along opposite longitudinal edges of the second guide groove  431 , respectively, to prevent the position fixing member  320  from being separated from the second guide groove  431 .  
         [0101]     Each fixing groove  440  is formed at one longitudinal edge of the second guide  430  in order to fix the folding rod  300  which has moved along the second guide  430 .  
         [0102]     Meanwhile, in accordance with the exemplary embodiment of the present invention, it is preferred that the laundry folder further include a weight  500  which prevents the laundry supported by the folding rod  300  in a seated state from being separated from the folding rod  300 , and smoothes out wrinkles on the laundry during the drying operation.  
         [0103]     As shown in  FIG. 7 , it is preferred that the weight  500  be provided, at one end thereof, with a nipper, in order to allow the weight  500  to be easily attached to a lower end of the laundry.  
         [0104]     Thus, the weight  500  applies a load to the laundry seated on the seat member  310  of the folding rod  300  in a gravity direction, thereby preventing the laundry from being separated from the seat member  310  while smoothing out wrinkles on the laundry during the drying operation.  
         [0105]     The controller  600  according to the exemplary embodiment of the present invention controls the operations of the drum dryer  100  and cabinet dryer  200 .  
         [0106]     The controller  600  may be equipped in one of the drum dryer  100  and cabinet dryer  200 , or may be equipped in either the drum dryer  100  or the cabinet dryer  200 . In the exemplary embodiment of the present invention, the controller  600  is illustrated as being equipped in the drum dryer  100 .  
         [0107]     Where two controllers  600  are equipped in the drum dryer  100  and cabinet dryer  200 , respectively, it is preferred that the two controllers  600  be connected by a data cable (not shown), for information transfer therebetween.  
         [0108]     Meanwhile, the controller  600  may be configured to control the drum dryer  100  and cabinet dryer  200  in an independent manner or in a linked manner.  
         [0109]     Hereinafter, the drying operation and functions of the composite washing system provided with the laundry folder in accordance with the exemplary embodiment of the present invention will be described.  
         [0110]     First, laundry is laid on the shelves  221 , or is hung on the hanger bar  222  in the body  210  of the cabinet dryer  200 .  
         [0111]     If the laundry to be hung on the hanger bar  221  has a long length, the folding rods  300   a  and  300   b  are mounted.  
         [0112]     In this case, the position fixing member  320  of the second folding rod  300   b  is first inserted into the insertion groove  410  of the folding rod guide. In this state, the position fixing member  320  of the second folding rod  300   b  is moved along the first guide groove  421  of the first guide  420 .  
         [0113]     Thereafter, the position fixing member  320  of the second folding rod  300   b  is vertically moved along the second guide groove  431  of the second guide  430  to a fixing level at which the laundry does not come into contact with the bottom of the cabinet dryer  200 . The fixing level may be appropriately determined in accordance with the length of the laundry. Subsequently, the position fixing member  320  of the second folding rod  300   b  is firmly fitted in the fixing groove  440  corresponding to the fixing level. As described above, the fixing groove  440  is formed at one longitudinal edge of the second guide  430 . Thus, the second folding rod  300   b  is fixedly mounted to the body  210  of the cabinet dryer  200 .  
         [0114]     Thereafter, the first folding rod  300   a  is inserted into the insertion groove  410  of the folding rod guide, and is then moved along the first guide  420  to a desired position.  
         [0115]     In this state, a portion of the laundry is wrapped around the bottom of the first folding rod  300   a  such that the laundry is folded. Thereafter, the laundry is seated on the top of the second folding rod  300   b.    
         [0116]     Meanwhile, if the laundry is likely to slip off the second folding rod  300   b , the weight  500  is attached to the lower end of the laundry in order to prevent the laundry from slipping off the second folding rod  300   b.    
         [0117]     After the hanging of the laundry is completely achieved in the above-described manner, electric power is supplied to the hot air supplier  130 , thereby causing hot air to be supplied to the second air supply duct  122  of the hot air supply path.  
         [0118]     Thereafter, the valve  125  is controlled to guide the hot air flowing through the second air supply duct  122  into the hot air inlet duct  241  of the cabinet dryer  200 .  
         [0119]     The hot air introduced into the hot air inlet duct  241  is discharged into the body  210  of the cabinet dryer  200 . Thus, the laundry is dried.  
         [0120]     The air which has become humid after being used to dry the laundry is guided through the condenser  140 , so that the air is dried while being condensed to remove moisture therefrom. The dried air is then heated to a high temperature while passing through the drying heater  131 . The resultant hot air is then re-supplied to the body  210  of the cabinet dryer  200 .  
         [0121]     Thus, the laundry is dried as the above-described air flow is repeated for a predetermined time.  
         [0122]     The above-described composite washing system according to the present invention has various advantages as follows.  
         [0123]     First, air flowing in the drum dryer and cabinet dryer is continuously circulated without being discharged out of the dryers in accordance with the present invention. Accordingly, the air used in the drying cycle has no influence on the indoor environment. Therefore, the present invention can provide a composite washing system having a suitable built-in structure.  
         [0124]     Second, in accordance with the present invention, humid air discharged from the drum dryer and cabinet dryer is condensed by the air condenser, so that moisture contained in the air is removed. Accordingly, it is possible to effectively dry laundry.  
         [0125]     Third, in accordance with the present invention, the cabinet dryer is equipped with the laundry folder. Accordingly, it is possible to dry laundry having a long length in a state of receiving the laundry in the cabinet dryer without wrinkling the laundry, and thus, to enhance the reliability of the composite washing system.  
         [0126]     It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
