BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a detergent supply apparatus for a laundry machine, and more particularly to, a fluid detergent and fabric softener box assembly which can be attached and detached to/from a detergent supply apparatus, and temporarily stores a fluid detergent and a fabric softener until they are selectively introduced into a washing room in water supply, and a detergent dispenser having the same. 
     2. Description of the Related Art 
     In general, a drum laundry machine is installed such that an outer circumferential surface of a cylindrical washing drum is positioned in the up-down direction, and washes laundry in a beat-wash manner using a fall head produced when the washing drum rotates. The drum laundry machine roughly includes a main body forming the exterior appearance, a tub installed in the main body and filled with wash water, and a washing drum rotatably installed in the tub with a plurality of dehydration holes on its wall surface. In addition, a detergent supply apparatus which dissolves a detergent using wash water supplied from an outer water supply source to the inside of the washing drum, and supplies the wash water mixed with the detergent to the inside of the washing drum is installed on the upper side of the tub. Therefore, the drum laundry machine can automatically perform several washing processes such as primary washing, main washing, rinsing, bleaching and dehydration under the control of a control unit by a user&#39;s manipulation, and perform various washing processes by supplying a detergent or a fabric softener necessary for each washing process to the inside of the wash tub. 
       FIG. 1  is a perspective view illustrating a state where a detergent container of a detergent supply apparatus installed in a general drum laundry machine is taken out, and  FIG. 2  is a schematic vertical-sectional view illustrating a structure of the detergent supply apparatus shown in  FIG. 1 . The detergent supply apparatus of the general drum laundry machine will be described with reference to the above drawings. 
     The detergent supply apparatus of the general drum laundry machine includes a detergent container housing  30  coupled to one side of an upper portion of a front surface of a main body  10  of the drum laundry machine, a detergent container  40  provided with a receiving groove which can receive a detergent, and installed in the detergent container housing  30  to be taken out, and a dispenser  20  for water supply which supplies wash water to the detergent container  40 . In order to use the laundry machine with the above construction, as illustrated in  FIG. 1 , a user takes out some portion of the detergent container  40  toward the front surface of the main body  10  of the drum laundry machine, puts a detergent and a fabric softener in respective detergent receiving portions separated and partitioned in the detergent container  40 , pushes the detergent container  40  into the detergent container housing  30 , and operates the laundry machine. 
     When the laundry machine is operated, respective washing processes are performed under the control of a control unit. A water supply valve  11  is opened, so that wash water is supplied to the inside of the drum laundry machine. The wash water supplied to the inside of the drum laundry machine is supplied to the dispenser  20  for water supply through a connection hose. The wash water supplied to the dispenser  20  for water supply is introduced into the detergent container  40  positioned therebelow, mixed with the detergent or the fabric softener, and supplied to the inside of a tub  50  through a water supply hose  12 . 
     Meanwhile, the detergent container  40  of the detergent supply apparatus described above is constructed such that the detergent and the fabric softener are dissolved by the wash water supplied to the inside thereof, and supplied to the inside of the tub  50  during a washing process. Here, the detergent remains in the detergent container  40 . As the above process is repeated, the residual detergent is accumulated in the detergent container  40 . Therefore, a cleaning task is required to remove the detergent residues in every certain period. 
     However, the detergent container  40  is not completely separated from the detergent container housing  30 , but partially taken out to the front of the main body  10  by a defined width. It is thus very difficult for the user to do the cleaning task for removing the detergent residues. Moreover, when the user takes out the detergent container  40  to the front of the main body  10 , puts the detergent or the fabric softener in the detergent container  40 , and pushes the detergent container  40  into the detergent container housing  30 , the detergent or the fabric softener may flow over the detergent container  40 . Accordingly, the user must carefully put the detergent and the fabric softener in the detergent container  40 , which causes inconvenience in use. 
     In the meantime, with diversification and functionality improvement of the detergent, not only a powder washing detergent formed of fine particles but also a fluid washing detergent formed in a liquid phase has been increasingly used. In this aspect, since the detergent supply apparatus described above supplies a powder washing detergent, and a liquid-phase fabric softener and bleaching agent to the inside of a washing space, it can supply only the powder washing detergent to the inside of the washing space during a washing stroke composed of primary washing and main washing. However, the detergent supply apparatus is not provided with a fluid detergent supply means which can separately supply a liquid-phase washing detergent to perform not bleaching and rinsing functions but a washing function. As a result, there is limitation on satisfying functionality by the user&#39;s various demands.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Hereinafter, the present invention will be described in detail with reference to an embodiment and the accompanying drawings. 
       FIG. 3  is an exploded perspective view illustrating a fluid detergent and fabric softener box assembly according to an embodiment of the present invention,  FIG. 4  is an assembled view illustrating the fluid detergent and fabric softener box assembly according to the embodiment of the present invention,  FIG. 5  is a top view illustrating a main body,  FIG. 6  is a bottom view illustrating a cap,  FIG. 7  is a view illustrating a front coupled portion of the cap and the main body,  FIG. 8  is a rear cut perspective view illustrating the fluid detergent and fabric softener box assembly according to the present invention, and  FIG. 9  is a view illustrating a rear coupled portion of the cap and the main body of the fluid detergent and fabric softener box assembly, when seen from the top. 
     The fluid detergent and fabric softener box assembly according to the embodiment of the present invention includes a main body  100  storing a fluid detergent and a fabric softener, and a cap  200  coupled to an upper portion of the main body  100 . The main body  100  has an inclined bottom surface. As a whole, the depth of the main body  100  increases from the front to the rear. Here, when a user sees a dispenser from a drum laundry machine, the side near to the user is referred to as the front, and the side distant from the user is referred to as the rear. A storage space defined in the main body  100  is partitioned into a fluid detergent storage space  110  and a fabric softener storage space  120  by a barrier  130 . In addition, the main body  100  includes a front seating portion  140  and side seating portions  150  to fix a position of the cap  200  and support the cap  200 , when the cap  200  is coupled to the main body  100 . Front seating protrusions  240  of the cap  200  discussed later are fitted onto the front seating portion  140 . Moreover, since the depth of the main body  100  decreases toward the front, the height of the barrier  130  also decreases, so the intensity of the barrier  130  may be weakened at the front. However, according to the embodiment of the present invention, since the barrier  130  can be formed as high as the front seating portion  140  at the front, the intensity of the barrier  130  can be improved. 
     Also, pipes  160  ( 162  and  164 ) which provide passages for sucking a mixed solution of the fluid detergent and water or a mixed solution of the fabric softener and water so as to introduce the same into a wash tub are formed at the rear of the fluid detergent storage space  110  and the fabric softener storage space  120  of the main body  100 , respectively. The pipes  160  are covered with pipe covers  260  of the cap  200  discussed later at a defined interval. The mixed solutions in the storage spaces  110  and  120  are sucked through the intervals between the pipes  160  and the pipe covers  260 , and discharged to the wash tub side. 
     The cap  200  is coupled to the upper portion of the main body  100  so as to prevent the fabric softener or the fluid detergent from being splashed and mixed with each other due to a fall head of water, when water is supplied to the main body  100 , or prevent the same from overflowing into another storage space  110  or  120 . The cap  200  is roughly divided into a front portion  200   f  positioned at the front to cover front portions of the fluid detergent storage space  110  and the fabric softener storage space  120  of the main body  100 , respectively, and a rear portion  200   b  positioned at the rear. The rear portion  200   b  is lower than the front portion  200   f . A stepped portion is formed between the front portion  200   f  and the rear portion  200   b . When the box assembly is coupled to a dispenser upper cover  300 , the front portion  200   f  is exposed to the outside, and the rear portion  200   b  is hidden by the dispenser upper cover  300  and thus is not seen from the outside. The front portion  200   f  is placed on the dispenser upper cover  300 , and the rear portion  200   b  is positioned below a dispenser lower cover  400 , particularly, below water supply holes  471  and  472  of the dispenser lower cover  400 , so that water can flow thereinto. Since the rear portion  200   b  is lower than the front portion  200   f,  the rear portion  200   b  can be easily inserted through a fluid detergent and fabric softener box assembly mounting space  320  (refer to  FIG. 12 ) of the dispenser upper cover  300 , and located below the dispenser lower cover  400 . 
     In addition, identically to the main body  100 , the front portion  200   f  positioned at the front of the cap  200  is partitioned into a fluid detergent-side cap  210  and a fabric softener-side cap  220  by a barrier  230 . A lower portion of the barrier  230  of the cap  200  forms a groove  230   g , so that the barrier  130  of the main body  100  can be inserted into the groove  230   g . The front seating protrusions  240  are formed at the front of the cap  200 . The front seating protrusions  240  are downwardly extended from the fluid detergent-side cap  210  and the fabric softener-side cap  220  at a defined interval therefrom. The front seating portion  140  of the main body  100  is inserted into this interval. 
     Moreover, the cap  200  has side fixing ribs  252  on its side surfaces. The height of the side fixing ribs  252  slightly increases toward the upper side. The side fixing ribs  252  serve to tightly engage the cap  200  with the side seating portions  150  of the main body  100 . 
     Further, the rear portion  200   b  positioned at the rear of the cap  200  includes the pipe covers  260  which cover the pipes  160  of the main body  100 , and a rear fixing hook  270 . Here, the pipe  160  of the main body  100  has cover fixing protrusions  162  at its lower portion so as to fix the pipe cover  260 . The fixing protrusions  162  are provided in a plural number at certain intervals along the circumference of the pipe  160 . At this time, an inner diameter of the pipe cover  260  is slightly larger than an outer diameter of the pipe  160 , and a top surface of the pipe cover  260  is formed at a certain interval from a top surface of the pipe  160  of the main body  100 . Accordingly, the fluid detergent mixed water or the fabric softener mixed water flows into a gap between the inner diameter of the pipe cover  260  and the pipe  160 , and is introduced into a washing room through the pipe  160 . Water used to produce the fluid detergent mixed water or the fabric softener mixed water is supplied from the dispenser upper cover  300  to the fluid detergent storage space  110  or the fabric softener storage space  120  of the main body  100 , particularly, to open side surfaces which are not covered by the pipe covers  260  of the cap  200 . In this construction, top surfaces of portions near to the barrier  130  which separates the fluid detergent storage space  110  from the fabric softener storage space  120  are covered with the pipe covers  260 , so water is supplied into the storage spaces  110  and  120  through side surfaces distant from the barrier  130 , i.e., outer side surfaces of the main body  100 . It is thus possible to considerably prevent the fluid detergent and the fabric softener from being splashed into another storage space  110  and  120  due to a fall head of water in preparation of mixed water, or prevent bubbles which may be generated in preparation of fluid detergent mixed water from overflowing into the fabric softener storage space  120 . 
     Meanwhile, bottom ends of the pipes  160  of the main body  100  are positioned slightly lower than bottom surfaces of the storage spaces  110  and  120  of the main body  100 . As a result, the fluid detergent mixed water or the fabric softener mixed water can be introduced into the washing room by a siphon effect without remaining in the storage space  110  or  120 . 
     In addition, the cap  200  has the rear fixing hook  270  at the rear of the pipe covers  260 , and the main body  100  has rear fixing protrusions  170  in a position corresponding thereto. The main body  100  and the cap  200  are firmly fixed by the rear fixing protrusions  170  and the rear fixing hook  270 , and the rear fixing hook  270  is prevented from being upwardly lifted by the rear fixing protrusions  170 . Here, preferably, the pipe covers  260  which are near to the rear fixing protrusions  170  have a slight interval from a rear surface of the main body  100 . In order to separate the cap  200  from the main body  100 , the user slightly pushes the main body  100  to the front, and unhooks the rear fixing hook  270  from the rear fixing protrusion  170 , thereby easily separating the cap  200  from the main body  100 . 
     In the meantime, the fluid detergent and fabric softener box assembly according to the present invention can be attached and detached to/from the dispenser. As set forth herein, since the portion hidden below the dispenser upper cover  300  and the portion exposed to the outside are formed with the stepped portion, the fluid detergent and fabric softener box assembly can be position-fixed in the dispenser. As the fluid detergent and fabric softener box assembly according to the present invention is detachably formed, the user can separate the box assembly from the dispenser and clean the box assembly, thereby maintaining cleanliness. Moreover, since the main body  100  and the cap  200  can be separated from each other, the user can easily clean the pipes  160  or the pipe covers  260  for bringing the siphon effect. 
       FIG. 10  is a view illustrating a top surface of the dispenser lower cover  400  according to the embodiment of the present invention, and  FIG. 11  is a view illustrating a bottom surface of the dispenser lower cover  400  according to the embodiment of the present invention. The dispenser lower cover  400  includes holes for a region  310  into which a main washing detergent is introduced, a region  320  on which the fluid detergent and fabric softener box assembly is mounted, and a region  330  into which a primary washing detergent is introduced, and water supply inlets  410 ,  430  and  440  for supplying water to the respective regions. In addition, a passage  451  for fluid detergent which guides water from the water supply inlets  410  and  430 , which supply water to the fluid detergent and fabric softener box assembly, to the water supply hole  471  for fluid detergent is formed on the top surface of the dispenser lower cover  400 , and a distribution rib  450  which distributes the water supplied through the water supply inlet  410  to the passage  451  for fluid detergent and a passage for main washing detergent is also formed thereon. The water supplied through the water supply inlet  410  is supplied to the fluid detergent storage space  110  of the fluid detergent and fabric softener box assembly through the water supply hole  471  for fluid detergent along the passage  451  for fluid detergent. Moreover, water supplied through the water supply inlets  410  and  430  to introduce the fabric softener is supplied to the fabric softener storage space  120  of the fluid detergent and fabric softener box assembly through the water supply hole  472  for fabric softener along a passage  421  for fabric softener. 
     Here, in order to prevent the fabric softener from being introduced into the washing room early because the water supplied through the water supply inlet  410  is splashed against the distribution rib  450 , it is necessary to restrict a shape of an end of the distribution rib  450 . A height of an endmost portion of the end of the distribution rib  450  on the side of the water supply inlet  410  is restricted to within 3.5 mm, and the height smoothly and gradually increases from the endmost portion to about 15 mm. That is, a length of a chamfered portion of the end of the distribution rib  450  is preferably over at least 15 mm. As the end of the distribution rib  450  is smoothly formed, the water supplied through the water supply inlet  410  is not splashed against the distribution rib  450 . 
     In addition, when water is supplied to the fluid detergent storage space  110  through the water supply inlet  410 , if the supplied water overflows into the fabric softener storage space  120  or bubbles of the fluid detergent overflow into the fabric softener storage space  120 , the fabric softener may be introduced early or diluted. In order to prevent the foregoing problem, a plurality of ribs  400   r  are formed on the bottom surface of the dispenser lower cover  400  facing the rear portion of the fluid detergent and fabric softener box assembly. The ribs  400   r  can more or less prevent water from flowing from the fluid detergent storage space  110  to the fabric softener storage space  120  or from the fabric softener storage space  120  to the fluid detergent storage space  110 . Moreover, a water supply hole rib  471   r  for fluid detergent and a water supply hole rib  472   r  for fabric softener which guide water in water supply to prevent splashing are formed in the water supply hole  471  for fluid detergent and the water supply hole  472  for fabric softener. Like the ribs  400   r , the water supply hole rib  471   r  for fluid detergent and the water supply hole rib  472   r  for fabric softener can prevent overflowing of the bubbles of the fluid detergent. 
     Further, the dispenser lower cover  400  includes a groove  400   g  so that the barrier  130  of the main body  100  of the fluid detergent and fabric softener box assembly can be inserted thereinto. The groove  400   g  is necessary to insert the rear portion of the fluid detergent and fabric softener box assembly into the lower portion of the dispenser lower cover  400 . Furthermore, as the barrier  130  is engaged with the groove  400   g , the fluid detergent and fabric softener box assembly can be position-fixed to some extent. Still furthermore, the dispenser lower cover  400  includes a rib  400   a  slightly protruding into the region  320  on which the fluid detergent and fabric softener box assembly is to be mounted, and the groove  400   g  is formed in the rib  400   a . The reason is that it is much easier to bore the groove  400   g  in the rib  400   a  than in a wall. Still furthermore, since the ribs  400   r  can be extended toward the rib  400   a , it is possible to efficiently prevent overflowing of the bubbles of the fluid detergent. 
       FIG. 12  is a view illustrating a top surface of the dispenser upper cover according to the embodiment of the present invention, and  FIG. 13  is a view illustrating a state where the fluid detergent and fabric softener box assembly is mounted on a dispenser cover formed by coupling the dispenser upper cover to the dispenser lower cover. The dispenser upper cover  300  is coupled to the dispenser lower cover  400 , has passage shapes corresponding to those of the dispenser lower cover  400 , and prevents overflowing or splashing of water introduced along the passages. In addition, the dispenser upper cover  300  includes holes for the region  310  into which the main washing detergent is  5  introduced, the region  320  on which the fluid detergent and fabric softener box assembly is mounted, and the region  330  into which the primary washing detergent is introduced in positions corresponding to the dispenser lower cover  400 . When the fluid detergent and fabric softener box assembly is mounted on the dispenser cover, only the front portion  200   f  of the cap  200  is exposed to the top surface of the dispenser upper cover  300 . As described above, the fluid detergent and fabric softener box assembly can be mounted or taken out through the hole for the region  320  of the dispenser upper cover  300  on which the fluid detergent and fabric softener box assembly is mounted. When the user grasps the barrier  230  of the fluid detergent and fabric softener box assembly and inserts Is the rear portion  200   b  first through the hole of the dispenser upper cover  300 , some portion of the barrier  130  of the main body  100  is engaged with the groove  400   g  of the dispenser lower cover  400 . Moreover, the dispenser upper cover  300  has a rib  320   a  protruding into the hole around the hole. The side surfaces of the front portion  200   f  of the fluid detergent and fabric softener box assembly are placed on the rib  320   a . Accordingly, the fluid detergent and fabric softener box assembly is not inserted more deeply into the region  320  on which the fluid detergent and fabric softener box assembly is mounted, but position-restricted. 
     Although the present invention has been described in detail in connection with the embodiment and the accompanying drawings, the scope of the invention is not limited thereto, but is defined by the appended claims.
