Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No. 10-2015-0094885 and 10-2015-0094886, filed on Jul. 2, 2015, the contents of which are incorporated by reference herein in their entirety. 
     BACKGROUND 
     Field 
     The present disclosure relates to a condensation type dryer. 
     Discussion of the Related Art 
     In general, a laundry processing apparatus is an apparatus for processing the laundry by applying physical and chemical actions to the laundry, and collectively refers to a washer for removing contaminants on the laundry, a dehydrator for dehydrating the laundry by rotating a washing tub containing the laundry at high speed, and a dryer for drying wet laundry by applying cold air or hot air to a washing tub. 
     A laundry processing apparatus capable of drying clothing may be classified as an exhaust type drying system and a circulation type (or a condensation type) drying system based on the flowing method of air in supplying air (i.e., hot air) of a high temperature to clothing. 
     The circulation type drying system is configured to dehumidify moisture from air discharged by a tub, heat the air again, and supply the heated air to the inside of the tub again. 
     The exhaust type drying system is configured to supply heated air to the inside of the tub, but to discharge air discharged by the tub to the outside of a laundry processing apparatus without supplying the discharged air to the inside of the tub. 
     In a conventional condensation type drying system, a condensate discharge container for storing a condensate is inserted in the front and back direction of a cabinet. Furthermore, the conventional condensate discharge container is disposed over a drum so that a user can lift up the condensate discharge container easily. 
     However, there is a problem in that the space corresponding to the length of the condensate discharge container must be secured at the front of the washing machine due to the structure of the condensate discharge container that is disposed in a front to back direction. 
     Furthermore, there are problems in that the center of gravity of the drying system rises and the drying system becomes vulnerable to vibration when the condensate discharge container is filled with a condensate because the condensate discharge container is disposed over the drum. 
     Often, the dryer is stacked on the upper side of the drum washing machine. 
     If the dryer is stacked on the upper side of the drum washing machine as described above, there are problems in that the condensate discharge container placed over the drum is placed above the chest level of a user, which makes it difficult to draw the condensate discharge container out. 
     SUMMARY 
     One object of the present disclosure is to provide a dryer capable of minimizing a space required to draw a condensate discharge container out. 
     Another object of the present disclosure is to provide a dryer, which is capable of increasing the utilization of the space within a cabinet and increasing the capacity of a drum by disposing a condensate discharge container under the drum. 
     Yet another object of the present disclosure is to provide a dryer capable of further lowering the center of gravity when a condensate is stored. 
     Further yet, another object of the present disclosure is to provide a dryer which enables a user to draw the condensate discharge container out easily. 
     Another object of the present disclosure is to provide a dryer capable of uniformly distributing a load to the entire dryer by disposing the condensate discharge container at the front of the drum. 
     Still yet another object of the present disclosure is to provide a dryer, which is capable of minimizing a space attributable to the drawing of the condensate discharge container and reducing vibration because the center of gravity is lowered through a generated condensate by laterally disposing the condensate discharge container under the front of the drum. 
     Still yet another object of the present disclosure is to provide a dryer capable of drawing the condensate discharge container out easily although the dryer is stacked over the drum washing machine. 
     Technical objects to be achieved by the present invention are not limited to the aforementioned objects, and those skilled in the art may understand other technical objects from the following description. 
     A dryer according to one embodiment of the present invention includes a cabinet with an entry hole formed on the front surface of the cabinet, a door being installed in the entry hole, a drum disposed within the cabinet and configured to rotate with the laundry received within the drum, an evaporator disposed within the cabinet and configured to remove moisture from air circulating through the drum by condensing the moisture, a condensate housing disposed within the cabinet and configured to collect a condensate condensed by the evaporator, a drawer space disposed under the entry hole and depressed backward from the front surface of the cabinet, a drawer disposed in the drawer space and configured to be rotated based on one side of the drawer and pulled out from the drawer space, a condensate discharge container configured to store the condensate of the condensate housing, the condensate discharge container being detachably held in the drawer, and exposed to a user when the drawer is pulled out, and a guide supporter configured to couple a cabinet-side structure and a drawer-side structure and to guide the rotation of the drawer with respect to the cabinet. 
     When the drawer is pulled out, the drawer may be pulled out from the drawer space along with the condensate discharge container. 
     When the drawer is pulled out, the drawer may be pulled out from the drawer space and the condensate discharge container may remain in the drawer space. 
     The drawer may be installed in a horizontal direction in such a way as to be rotated around the cabinet. The guide supporter may include a pivot disposed on the one side of the drawer and configured to form a vertical rotating center of the drawer. 
     The guide supporter may further include a rotation guide disposed on the other side of the drawer and configured to guide the rotation of the drawer. 
     The rotation guide couples the drawer and the cabinet. 
     The rotation guide couples the drawer and the condensate housing. 
     The drawer may be installed up and down in such a way as to be rotated around the cabinet. The guide supporter may include pivots disposed on both sides of the drawer and configured to form a horizontal rotating center of the drawer. 
     The condensate discharge container may have a length longer in a left and right width direction than in a front and back direction. 
     The drawer may include a bucket configured to store a condensate overflowed from the condensate discharge container.

The overflow path may be disposed on at least one of a bucket side and a condensate housing side. The coupling of the bucket and the condensate housing by the overflow path may be released when the drawer is pulled out from the drawer space. The bucket and the condensate housing may be coupled by the overflow path when the drawer is received in the drawer space. 
     A latch may be disposed in at least one of the drawer-side structure and the cabinet-side structure. A hook may be disposed in another of the drawer-side structure and the cabinet-side structure. The state in which the drawer-side structure has been received in the drawer space may be maintained by mutual engagement of the latch and the hook.

     DETAILED DESCRIPTION 
     The below embodiments are merely provided to complete the disclosure of the present invention and to allow a person having ordinary skill in the art to which the present invention pertains to completely understand the category of the invention; they are not limiting. Embodiments of the present invention are defined by the category of the claims only. In the specification, the same reference numerals designate the same elements. 
     A dryer according to a first embodiment is described below with reference to  FIGS. 1 to 8 . 
     The dryer according to the first embodiment includes a cabinet  10  configured to form an external appearance, a drawer space  19  depressed backward from the front surface of cabinet  10 , a drum  30  disposed within cabinet  10  which is configured to have the laundry received therein and rotated, a driving unit  40  configured to rotate drum  30 , a heat pump unit  50  configured to dry the laundry by heating air circulating in the drum  30  and to remove moisture from the circulating air by condensing the moisture, an air circulation unit  60  configured to circulate the air of drum  30 , a condensate storage module  80  disposed in cabinet  10  and configured to include a condensate discharge container  82  in which a condensate condensed by heat pump unit  50  is moved and stored, a drawer  70  disposed in the drawer space  19  and rotated forward from the cabinet  10 , thereby exposing the condensate discharge container  82  to a user, and a support guide  90  disposed in the drawer  70  and the cabinet  10  and configured to guide the rotation of the drawer  70 . 
     In the present embodiment, drawer  70  and condensate discharge container  82  are together pulled out forward from the cabinet  10 . 
     Condensate discharge container  82  is hidden in drawer space  19  and is exposed out of the cabinet  10  when drawer  70  is pulled out. 
     Condensate discharge container  82  maintains the state in which it is hidden in the drawer space  19  until drawer  70  is pulled out. Drawer  70  is coupled to a guide supporter  90  and is pulled out forward from the cabinet  10  along the guide supporter  90 . 
     Condensate discharge container  82  and drawer  70  are collectively defined as a drawer assembly. 
     Drawer space  19  in which the drawer assembly is received is formed in the cabinet  10 . Drawer space  19  may be formed on the outside of cabinet  10 . Drawer space  19  may be disposed under the drum  30 . Drawer space  19  may be disposed under an entry hole  17  through which the laundry is inputted. 
     Cabinet  10  forms an external appearance of the dryer. Cabinet  10  has a door  15  disposed at its front. Door  15  is rotated left or right and opens/shuts the inside of the cabinet  10 . 
     Cabinet  10  includes a front cover  11 , a top plate  12 , side covers  13 , a rear cover  14 , and a base  16 . Door  15  is disposed in the front cover  11 . 
     Entry hole  17  through which the laundry is inputted is formed in the front cover  11 . 
     Drawer space  19  is placed on the lower side of the front cover  11 . Drawer space  19  is depressed backward from the front cover  11 . 
     When the drawer  70  is received in drawer space  19 , it is flush with the front cover  11 . 
     In other embodiments, drawer space  19  may be placed inside the front cover  11 . That is, the drawer space  19  may be disposed in such a way as to be surrounded by the front cover  11 . 
     Cabinet  10  may generally have a rectangular parallelepiped shape. 
     Door  15  is disposed on the front surface of cabinet  10  and operates so that it rotates left or right. 
     Entry hole  17  opened/shut by door  15  communicates with drum  30 . 
     Drum  30  is disposed within the cabinet  10 . In order to maximize the capacity of the drum  30 , the condensate storage module  80  is disposed under the drum  30 . 
     As such, the diameter of drum  30  within the cabinet  10  can be maximized because other operational parts are not disposed over the drum  30 . 
     Drum  30  is formed in a cylindrical shape. Drum  30  has a lifter  31  disposed therein. Lifter  31  lifts up the laundry within the drum while rotating and then lets the laundry freely fall. 
     Driving unit  40  includes a driving motor  42  fixed to the cabinet  10 . A driving shaft  41  of driving motor  42  is coupled to the back of the drum  30 . Drum  30  may be rotated forward or backward by the rotation of the driving motor  42 . 
     A circulation flow path along which air within the drum circulates is formed in the drum  30 . 
     In the present embodiment, air has been illustrated as flowing from the back of the drum  30  to the inside of the drum, and air has been illustrated as being discharged to the front of the drum. 
     In some embodiments, the circulation flow path along which air within the drum circulates may be formed in various ways. 
     Air circulation unit  60  includes an impeller  61 , an air circulation motor  62  configured to rotate the impeller  61 , and the circulation flow path along which air discharged by the impeller  61  is guided 
     In the present embodiment, impeller  61  is disposed inside the rear cover  14 . More specifically, impeller  61  is disposed between the rear cover  14  and the drum  30 . 
     Air circulation motor  62  is placed over the base  16  and placed under the drum  30 . Air circulation motor  62  rotates the impeller  61 . Impeller  61  is a kind of centrifugal ventilation fan for discharging air in a cylindrical direction. 
     In other embodiments, the circulation flow path may be configured in various ways. 
     In the present embodiment, the circulation flow path includes (i) a rear duct  63  configured to guide circulation air, discharged by the impeller  61 , to the drum  30 , (ii) a heat pump duct  64  configured to guide, circulation air supplied by the heat pump unit  50 , to the impeller  61 , and (iii) a drum duct  65  configured to guide, circulation air discharged by the drum  30 , to the heat pump unit  50 . 
     Rear duct  63  for guiding air discharged by the impeller  61  to the drum  30  is formed in the rear cover  14 . The air guided to the drum  30  through the rear duct  63  flows into the drum  30  through the back of the drum  30 . 
     To this end, a drum inlet  32  is formed at the back of the drum  30  so that air can flow into the drum  30 . 
     Drum inlet  32  is disposed in the periphery of the driving shaft  41 . Accordingly, when the drum  30  is rotated, circulation air discharged by the impeller  61  can flow into the drum through the drum inlet  32 . 
     Heat pump duct  64  is disposed between the impeller  61  and the heat pump unit  50 . Drum duct  65  is disposed between the drum  30  and the heat pump unit  50 . 
     Heat pump unit  50  may drive a refrigerant in a heat pump cycle. Heat pump unit  50  may heat circulation air using heat generated from a condenser and may condense moisture within the circulation air using heat generated from an evaporator. 
     Heat pump unit  50  according to the present embodiment may implement heating and condensation with respect to circulation air. 
     In an alternative embodiment, only a condenser for condensing moisture within circulation air may be installed. The condenser operates as an evaporator and has the same function as a second heat exchanger  54  of the present embodiment. In this case, an external air and the circulation air are thermally exchanged in the condenser. The condensate of the circulation air is generated by the condenser through the thermal exchange. A mechanism and structure for generating the condensate through the condenser is known to those skilled in the art, and thus a detailed description thereof is omitted. 
     Heat pump unit  50  includes a compressor  51  configured to compress a refrigerant, a first heat exchanger  52  configured to condense the compressed refrigerant by thermally exchanging the compressed refrigerant and circulation air, an expansion valve (not shown) configured to expand the refrigerant condensed by the first heat exchanger  52 , and the second heat exchanger  54  configured to evaporate the refrigerant expanded by the expansion valve by thermally exchanging the expanded refrigerant and the circulation air. 
     First heat exchanger  52  and second heat exchanger  54  are heat exchangers. 
     The expansion valve may be an electronic expansion valve. 
     First heat exchanger  52  is thermally exchanged with circulation air, and condenses a refrigerant. In the condensing process of the refrigerant, condensation heat of the refrigerant is discharged, and the discharged heat heats the circulation air. 
     The circulation air is heated by the condensation heat and used to dry the laundry. 
     Although not shown in the present embodiment, a heater (not shown) may be disposed in the circulation flow path, and the circulation air may be heated to a higher temperature using heat generated by the heater. 
     Second heat exchanger  54  is thermally exchanged with circulation air, and evaporates a refrigerant. In the evaporation process of the refrigerant, the refrigerant absorbs evaporation heat, and the circulation air is cooled by the evaporation heat. When the circulation air is cooled, moisture within the circulation air may be condensed, thereby being capable of generating a condensate. The moisture within the circulation air may include wash water evaporated from the laundry. 
     In the present embodiment, first heat exchanger  52  and second heat exchanger  54  are disposed over the base  16  in a line. A condensate housing  55  in which the first heat exchanger  52  and the second heat exchanger  54  are received is disposed over the base  16 . Second heat exchanger  54  and the condenser are disposed in a line within the condensate housing  55 . 
     The condensate of the circulation air is stored in the condensate housing  55  disposed within the cabinet  10  and is then moved to the condensate discharge container  82  by a condensate pump  84 . 
     That is, the dryer according to the present embodiment generates a condensate within the cabinet  10 , moves the condensate to the condensate discharge container  82  outside the cabinet  10 , and stores the condensate in the condensate discharge container  82 . 
     Circulation air discharged by drum  30  is supplied to the condensate housing  55  via the drum duct  65 . The circulation air is thermally exchanged with the second heat exchanger  54  within the condensate housing  55  and then thermally exchanged with the first heat exchanger  52 . 
     Second heat exchanger  54  is thermally exchanged with circulation air discharged by the drum  30 , and condensates moisture included in the circulation air. The condensate flows downward by its own weight and collects at the condensate housing  55 . 
     Condensate housing  55  has its bottom backward inclined. 
     Condensate pump  84  is disposed at the rear of the condensate housing  55 . The condensate pump  84  pumps the collected condensate toward the condensate discharge container  82 . 
     In the present embodiment, the circulation air flows from the front of the condensate housing  55  to the back because the drum duct  65  is disposed at the front of the condensate housing  55 . The condensate may naturally flow toward the back of the condensate housing  55  by the inclined direction and the circulation air. 
     The circulation air that is thermally exchanged with the second heat exchanger  54  and cooled is thermally exchanged with the first heat exchanger  52  disposed at the back of the second heat exchanger  54 . First heat exchanger  52  heats the circulation air. The circulation air heated by the first heat exchanger  52  flows into the impeller  61  through the heat pump duct  64 . 
     Condensate storage module  80  stores the condensate, collected at the condensate housing  55 , in the condensate discharge container  82 . 
     A user may separate the condensate discharge container  82  in which the condensate has been stored from the cabinet  10  and discard the condensate stored in the condensate discharge container  82 . 
     Condensate storage module  80  includes the condensate discharge container  82  detachably disposed in the cabinet  10 , the condensate pump  84  disposed in the cabinet  10  and configured to move a condensate, collected at the condensate housing  55 , toward the condensate discharge container  82 , and a condensation discharge hose  86  configured to guide the condensate, discharged by the condensate pump  84 , to the condensate discharge container  82 . 
     Condensate discharge container  82  is a space in which a condensate generated from the second heat exchanger  54  is stored. Condensate discharge container  82  may be separately disposed outside the cabinet  10 . 
     A condensate is also stored in the condensate housing  55 , but the condensate discharge container  82  is an element different from the condensate housing  55 . Condensate housing  55  is used to collect a condensate until at least a specific amount of the condensate is reached. Condensate discharge container  82  is a space for storing a condensate pumped by the condensate housing  55 . 
     Operation frequency of the condensate pump  84  can be reduced only when at least a specific amount of a condensate is pumped. 
     Condensate discharge container  82  is placed on the lower front side of the cabinet  10  and covered with the drawer  70 . 
     In the present embodiment, drawer  70  forms a face flush with the front cover  11 . Drawer  70  covers the entire condensate discharge container  82 . In some embodiments, the drawer  70  may cover only part of the condensate discharge container  82  or may not cover the condensate discharge container  82  at all. 
     Drawer  70  is disposed in drawer space  19 . Drawer  70  covers the drawer space  19 . In the present embodiment, condensate discharge container  82  may be held in the drawer  70  and pulled out forward from the cabinet  10  along with the drawer  70 . 
     Drawer  70  includes a drawer cover  71  configured to cover at least part of the condensate discharge container  82 , a bucket  87  disposed on the back surface of the drawer cover  71  and configured to have the condensate discharge container  82  held therein, and a drawer holder  72  disposed in the drawer cover  71  and connected to the cabinet  10 . 
     In some embodiments, drawer holder  72  may be omitted. If drawer holder  72  is omitted, the cabinet  10  and the drawer cover  71  are connected. Drawer holder  72  may be integrated with the drawer cover  71 . 
     The support guide  90  is disposed in the drawer holder  72 , and the drawer assembly is coupled to the cabinet  10  by the guide supporter  90 . 
     Condensate discharge container  82  is supplied with a condensate through the condensation discharge hose  86 , and stores the supplied condensate. 
     Condensate discharge container  82  is detachably disposed in the cabinet  10 . Condensate discharge container  82  is disposed in the drawer space  19  and is pulled out forward from the drawer space  19  along with the drawer  70 . 
     Condensate discharge container  82  is lengthily extended in the width direction of the cabinet  10 . That is, condensate discharge container  82  may have a length longer in the width direction than in the front and back direction. Further, condensate discharge container  82  may have a length longer in the up and down direction than in the front and back direction. 
     Condensate discharge container  82  formed in the width direction minimizes an insertion depth into the cabinet  10 . The length in which the condensate discharge container  82  is pulled out can be minimized because the depth inserted into the cabinet  10  is minimized. That is, a space required to pull out the condensate discharge container  82  is minimized because the length in the front and back direction of the condensate discharge container  82  is minimized. 
     When the condensate discharge container  82  is pulled out, a drawer space corresponding to at least a length in the front and back direction of the condensate discharge container  82  is required. In the present embodiment, such a drawer space can be minimized. 
     For example, there is no problem in pulling out the condensate discharge container  82  if there is a space to the extent that the door  15  can be open. Although the radius of the door  15  is small, the condensate discharge container  82  can be pulled out. 
     Condensate discharge container  82  is disposed at the front of the condensate housing  55 . Condensate discharge container  82  is disposed between the drawer  70  and the condensate housing  55 . Condensate discharge container  82  is disposed on the lower front side of the drum  30 . 
     Drum duct  65  is disposed on the lower front side of the drum  30 . Drum duct  65  is disposed between the condensate housing  55  and the condensate discharge container  82 . 
     Condensate discharge container  82  is disposed under the door  15 . Condensate discharge container  82  is disposed over the base  16 . 
     Condensate discharge container  82  has a length longer in the left and right width than in the front and back direction. There is an advantage in that the length in which the condensate discharge container  82  is pulled out can be minimized because the length of the condensate discharge container  82  is shorter in the front and back direction than in the left and right width as described above. 
     A condensate hole  81  is disposed on top of the condensate discharge container  82 . The condensate of the condensate housing  55  is supplied through condensate hole  81 . 
     Condensate discharge container  82  and the condensation discharge hose  86  may be directly coupled. In the present embodiment, a condensate dropping from the condensation discharge hose  86  flows into the condensate discharge container  82  through the condensate hole  81 . 
     The attachment/detachment structure of the condensate discharge container  82  can be implemented simply due to the structure in which a condensate drops. 
     Furthermore, a front and back direction length w 1  on the top surface of the condensate discharge container  82  is smaller than a front and back direction length w 2  on the bottom thereof. Accordingly, the condensate discharge container  82  has a cross section that becomes wider from the top to the bottom. 
     There is an advantage in that a user can lift up the condensate discharge container  82  more easily because the top of the condensate discharge container  82  is narrower. That is, a user can grasp the condensate discharge container  82  easily because the condensate discharge container  82  is short in the front and back direction and long in the width direction. 
     In the present embodiment, an incline plane  88  is formed on the back surface of the condensate discharge container  82  due to the difference between the front and back direction lengths w 1  and w 2 . Condensate discharge container  82  may have a trapezoid shape. In the present embodiment, however, the condensate discharge container  82  may have a generally vertical front surface and an inclined back surface. 
     Such a shape has been made by taking into consideration an angle when a user lifts up the condensate discharge container  82 . A user tends to lift up the condensate discharge container  82  while pulling it toward his or her side rather than to vertically lift up the condensate discharge container  82 . Incline plane  88  on the back surface of the condensate discharge container  82  has been made by taking into consideration such a use pattern. 
     There is an advantage in that the incline plane  88  can minimize interference with other elements of the cabinet  10  when a user lifts up the condensate discharge container  82 . 
     Furthermore, the bottom of condensate discharge container  82  is wider than the top thereof. Accordingly, condensate discharge container  82  does not fall although stored condensate moves around, and thus the condensate can be safely held in the condensate discharge container  82 . 
     The front surface of condensate housing  55  is inclined in accordance with the incline plane  88  of the condensate discharge container  82 . Accordingly, the upper front side of the condensate housing  55  is forward protruded, and the lower front side thereof is backward recessed. 
     The shaking of condensate discharge container  82  can be minimized because the front surface of the condensate housing  55  and the back surface of the condensate discharge container  82  are matched in shape and closely attached, and thus vibration can be suppressed when the drum  30  operates. 
     Furthermore, the center of gravity of the dryer can move downward because the condensate discharge container  82  is disposed under the drum  30 . That is, the center of gravity of the dryer further moves downward as a condensate is stored in the condensate discharge container  82 . Accordingly, stability can be improved when the drum  30  operates as the center of gravity of the dryer moves downward. 
     Furthermore, since condensate discharge container  82  is disposed at the front of the drum  30 , a variation in weight can be reduced in accordance with the driving unit  40 . That is, weight of the dryer can be distributed in the front and back direction because the driving unit  40  is disposed on the back side of the drum  30  and the condensate discharge container  82  is disposed on the front side of the drum  30  based on the front and back direction of the dryer. 
     As described above, the location of condensate discharge container  82  has an advantage in that vibration generated when the dryer operates can be reduced. 
     Condensate pump  84  is disposed at the back of the condensate housing  55 . 
     Condensation discharge hose  86  has one end coupled to the condensate pump  84  and has the other end coupled to the condensate hole  81 . 
     Condensate pump  84  may be disposed inside the rear cover  14 . In the present embodiment, a pump cover  85  is separately provided. Pump cover  85  is assembled with the rear cover  14 , thus hiding pump  84 . When pump  84  fails or is checked, pump cover  85  may be separated so that the condensate pump  84  is exposed. 
     Drawer  70  includes bucket  87  configured to receive a condensate overflowed from the condensate discharge container  82 . Bucket  87  is disposed on the back surface of the drawer  70 . Bucket  87  is integrated with the drawer  70 . In some embodiments, bucket  87  may be fabricated separately from the drawer  70  and then fixed to the drawer  70 . 
     Condensate discharge container  82  may be separated upward from the bucket  87 . Condensate discharge container  82  is held inside the bucket  87 . 
     Bucket  87  may receive at least part of the condensate discharge container  82 . In the present embodiment, bucket  87  is disposed under the condensate discharge container  82 , and part of the lower side of the condensate discharge container  82  is inserted into the bucket  87 . 
     Bucket  87  stores a condensate overflowed from the condensate hole  81 . Bucket  87  further includes a support rib  89  configured to support the condensate discharge container  82 . 
     Support rib  89  is formed on the inside surface of the bucket  87 . Condensate discharge container  82  is held in the support rib  89 . Condensate discharge container  82  is spaced apart by the height of the support rib  89 . Accordingly, a condensate overflowed from the periphery of the support rib  89  can be received. 
     The overflowed condensate may flow into the condensate housing  55 . To this end, an overflow path  100  for coupling the bucket  87  and the condensate housing  55  is installed. 
     A check valve  102  is installed on the overflow path  100 . Check valve  102  allows a condensate to flow only from the bucket  87  to the condensate housing  55 , but prevents a condensate from flowing in the opposite direction. Specifically, check valve  102  may prevent the wet steam of the condensate housing  55  from moving into the bucket  87 . 
     Overflow path  100  may be fabricated as a single part. In the present embodiment, overflow path  100  includes a first overflow joint pipe  101  coupled to the condensate housing  55  and a second overflow joint pipe  103  coupled to the bucket  87 . 
     Check valve  102  is installed on the first overflow joint pipe  101 . In some embodiments, check valve  102  may be installed on the second overflow joint pipe  103 . 
     First overflow joint pipe  101  and second overflow joint pipe  103  may be coupled or separated. 
     When drawer  70  is received in the drawer space  19 , first overflow joint pipe  101  and second overflow joint pipe  103  are coupled. When the drawer  70  is pulled out from the drawer space  19 , the first overflow joint pipe  101  and the second overflow joint pipe  103  are separated. Although the second overflow joint pipe  103  is separated from the first overflow joint pipe  101 , a fluid within the condensate housing  55  is prevented from flowing outward by the check valve  102 . 
     If overflow path  100  is formed of a single part, it may be disposed on at least one side of the bucket and the condensate housing. If overflow path  100  is formed of a single part, when drawer  70  is pulled out from the drawer space  19 , the connection of the bucket  82  and the condensate housing  55  by the overflow path  100  is released. If overflow path  100  is formed of a single part, when the drawer  70  is received in the drawer space  19 , the bucket  82  and the condensate housing  55  are coupled by the overflow path  100 . 
     Drawer  70  is disposed at the front of the condensate discharge container  82 . 
     In the present embodiment, the entire condensate discharge container  82  has been illustrated as being covered with the drawer  70 . In an alternative embodiment, only part of the condensate discharge container  82  may be covered with the drawer  70 . 
     Drawer  70  may be forward rotated and pulled out by a user&#39;s manipulation force. When drawer  70  is rotated and pulled out, condensate discharge container  82  is also pulled out forward. Condensate discharge container  82  is moved forward and exposed to a user. 
     Drawer  70  forms the front surface of the dryer along with the front cover  11 . 
     Drawer  70  is disposed on the lower side of the front cover  11 . 
     In the present embodiment, guide supporter  90  is disposed in order to pull out the drawer  70  forward by guiding the rotation of the drawer  70 . Guide supporter  90  couples the drawer assembly and a cabinet-side structure and guides the rotation of the drawer assembly. 
     A drawer-side structure may be the drawer  70 , the bucket  87 , or the drawer holder  72 . The cabinet-side structure may be the front cover  11 , the base  16 , or the condensate housing  55 . 
     In the present embodiment, the drawer assembly is supported by the guide supporter  90 , and guides the rotation of the guide supporter  90 . The drawer assembly is rotated around an axis disposed on one side thereof. 
     In the present embodiment, guide supporter  90  is horizontally rotated. 
     Guide supporter  90  includes a pivot  91  disposed on one side of the drawer  70  and configured to form the rotating center of the drawer assembly and a rotation guide  92  disposed on the other side of the drawer  70  and configured to guide the rotation of the drawer. 
     Guide supporter  90  supports a load of the drawer assembly including the bucket  87  and guides the rotation of the drawer assembly. 
     Pivot  91  is installed on the drawer holder  72 . Unlike in the present embodiment, the pivot  91  may be installed on the bucket  87 . 
     Rotation guide  92  is disposed on the side opposite the side of the drawer holder  72  based on the drawer  70 . Rotation guide  92  is formed to have an arc shape. 
     Rotation guide  92  may be fixed to the base  16  or the condensate housing  55 . Rotation guide  92  may be disposed under the bucket  87 . 
     Drawer  70  is held or coupled to the rotation guide  92 . A guide protrusion  93  is disposed in the drawer  70 . Guide protrusion  93  may move along the rotation guide  92 . Guide protrusion  93  may be disposed under the bucket  87 . 
     Pivot  91  supports a load of the drawer assembly on one side thereof, and the rotation guide  92  supports a load of the drawer assembly on the other side thereof. 
     The drawer assembly can be prevented from leaning toward any one side by the support of the pivot  91  and the rotation guide  92 . Accordingly, the rotation operation of the drawer assembly can be smoothly implemented. 
     Furthermore, when the drawer assembly is received in drawer space  19 , an optional latching unit for confining the drawer assembly to the drawer space may be further installed. The optional latching unit may be a latch. The latch may be installed on any one of the drawer-side structure and the cabinet-side structure and may form mutual engagement along with the other side. 
     Furthermore, a drawer elastic member (not shown) may be disposed between the drawer assembly and the cabinet  10 . When the latching of the latch is released, the drawer elastic member functions to push the drawer space  19  to the outside by applying an elastic force to the drawer assembly. When the drawer assembly is received in the drawer space  19 , the drawer elastic member is compressed and accumulates an elastic force. 
     The drawer-side structure may be the drawer  70 , the bucket  87 , or the drawer holder  72 . The cabinet-side structure may be the front cover  11 , the base  16 , or the condensate housing  55 . 
     When a user backward presses the drawer  70 , the latching of the latch may be released. When the latch is released, a drawer elastic member (not shown) for moving the drawer  70  by pushing it forward may be further disposed. 
     The drawer elastic member is disposed between the cabinet-side structure and the drawer assembly-side structure, and may provide an elastic force. 
     For example, the drawer elastic member may be installed on at least any one of the condensate housing  55 , that is, a cabinet-side structure, and the guide supporter  90 , that is, a drawer-side structure, and provide a forward elastic force. 
     For example, the drawer elastic member may be installed in the latch and may provide an elastic force. 
     When drawer  70  is pulled out, a user releases the latch by pushing the drawer  70  backward (i.e., “in”). Drawer  70  is forward pushed (i.e., “in”) and moved by the elastic force of the drawer elastic member. 
     When drawer  70  is received in the cabinet  10 , a user closely attaches the drawer  70  to the back, and thus the drawer  70  is engaged with the latch  95 . 
     The latching of the latch or the release of the latching is known to those skilled in the art, and thus a detailed description thereof is omitted. 
     Furthermore, when such mutual engagement is formed by the latch  95 , the first overflow pipe  101  and the second overflow pipe  103  are coupled. The coupling of the first overflow pipe  101  and the second overflow pipe  103  is maintained by the latch. 
     When the latching of the latch  95  is released, however, the first overflow pipe  101  and the second overflow pipe  103  are separated. 
     Guide supporter  90  and latch  95  function to reliably form the overflow path  100 , and prevent the condensate of the bucket  87  from leaking. 
     A dryer according to a second embodiment is described below with reference to  FIG. 9 or 10 . 
     In the dryer according to the second embodiment, the drawer assembly is rotated and pulled out forward from the drawer space  19 , but it is rotated up and down. 
     To this end, pivots  95  of the guide supporter  90  may be disposed in a left and right direction or horizontal direction with respect to the cabinet  10 . 
     Pivots  95  are installed on the left and right sides of the drawer  70 . 
     Pivots  95  are protruded from the drawer holder  72  of the drawer  70  to the left side and the right side, respectively. 
     Pivots  95  are horizontally disposed, and thus the drawer assembly may be rotated up and down around the pivots  95 . 
     The rotation of the drawer assembly can be implemented easily by the self-weight of the condensate discharge container  82 . 
     In order to confine the drawer assembly to the drawer space  19 , a latch  96  may be installed on the cabinet-side structure, and a hook  97  may be installed on the drawer assembly-side structure. 
     In the second embodiment, the latch  96  is disposed in the front cover  11 , and the hook  97  is disposed in the drawer  70 . 
     Hook  97  may optionally form mutual engagement with the latch  96 . 
     Upon the mutual engagement, the drawer assembly is received in the drawer space  19 . 
     The remaining elements are the same as those of the first embodiment, and thus a detailed description thereof is omitted. 
     The dryer according to an embodiment of the present invention has the following one or more effects. 
     First, there is an advantage in that a space required to pull out the condensate discharge container can be minimized because the condensate discharge container is laterally disposed. 
     Second, there is an advantage in that a drum having a higher capacity compared to the same size can be installed because a structure disposed over the drum within the cabinet is minimized and the condensate discharge container is disposed on the lower side of the drum, which has a relatively larger margin. 
     Third, there is an advantage in that the center of gravity is further lowered by a condensate generated in a dryer operation process because the condensate discharge container is disposed under the drum. 
     Fourth, there is an advantage in that only the condensate discharge container can be separated by lifting up the condensate discharge container exposed to a user after the drawer is pulled out. 
     Fifth, there is an advantage in that load imbalance in the front and back direction of the dryer can be minimized when a condensate is filled because the condensate discharge container is disposed at the front of the drum. 
     Sixth, there is an advantage in that the condensate discharge container is moved to the position where a user can grasp the condensate discharge container easily because the condensate discharge container is also rotated and pulled out when the drawer is rotated and pulled out. 
     Seventh, there is an advantage in that a load of the drawer can be reduced because the condensate discharge container remains in the drawer space and only the drawer is pulled out when the drawer is rotated and pulled out. 
     Eighth, there is an advantage in that the drawer assembly can be rotated and the condensate discharge container can be pulled out if there is a space to the extent that the door is open. 
     Those skilled in the art to which the present invention pertains will appreciate that the present invention may be implemented in other detailed forms without departing from the technical spirit or essential characteristics of the present invention. Accordingly, the aforementioned embodiments should be understood as being only illustrative, but should not be understood as being restrictive from all aspects. The scope of the present invention is defined by the following claims rather than the detailed description, and the meanings and scope of the claims and all changes or modified forms derived from their equivalents should be construed as falling within the scope of the present invention.
