  • a rear end portion of the guide recess 539 may be larger than the front end portion of the guide recess 539 so that the guide protrusion 425 may be guided toward the center of the guide recess 539 . Accordingly, when the detergent container 500 is inserted into the detergent container receiving unit 420 , the guide protrusion 425 may smoothly enter (engage) the guide recess 539 .
  • a concave part 537 may be formed on a lower surface of the case 530 so that the case 530 may be inserted or withdrawn without interfering with a front panel fastening part 309 (see FIG. 12 ) and a cover fastening part (see FIG. 12 ) in the detergent container loading port 304 and the detergent container receiving unit 420 , respectively. Details of the front panel fastening part 309 and a cover fastening part 428 are described below with reference to FIG. 12 .
  • FIG. 12 is an exploded perspective view of the cover and the front panel of FIG. 4
  • FIG. 13 is a view illustrating a rear surface of the front panel of FIG. 6 .
  • the detergent container loading port 304 is disposed at an upper portion of the cover 300 so that the detergent dispenser 500 may be inserted into and withdrawn from the upper portion of the cover 300 .
  • An upper portion of the detergent container loading port 304 protrudes forward (in a direction that is toward the front surface of the cabinet 100 ) to correspond to a shape of a rear surface of the door 2000 , and a central portion of the detergent container loading port 304 may have a sloped shape depressed backward (in a direction that is toward the rear surface of the cabinet 100 ).
  • a front part mounting recess 305 on which the front part 510 of the detergent container 500 is mounted, may be formed near the detergent container loading port 304 . Because the detergent container 500 is inserted into the detergent container loading port 304 and the front part 510 is mounted on the front part mounting recess 305 , the front part 510 may form part of a front surface of the cover 300 .
  • an upper side 5101 of the front part 510 protrudes from the front surface of the front part and is sloped relative to a lower side 5103 of the front part 510 , to correspond to the shape of the cover 300 , and, as a result, the front part 510 may have a shape with a bent portion 5102 extending in a circumferential direction between the upper side 5101 and the lower side 5103 .
  • the position of the detergent container receiving unit 420 in the front panel 400 may correspond to a position of the detergent container loading port 304 .

  • the detergent container gasket fixing rib 423 protrudes forward from a front edge (in a direction that is toward the front surface of the cabinet 100 ) of the detergent container receiving unit 420 .
  • the detergent container gasket fixing rib 423 is coupled (e.g., coupled by fitting) to the detergent container gasket 430 to provide a base for attaching the detergent container gasket 430 .
  • the detergent container gasket fixing rib 423 may be provided with a number of slits 424 that are elongated in a forward/backward direction.
  • the slits 424 are arranged in the detergent container fixing rib 423 and spaced apart from each other at a predetermined interval in a horizontal direction of the detergent container gasket fixing rib 423 .
  • the guide protrusion 425 may have a hook 426 that may be caught by the detergent container arresting part 5392 so that it is elastically coupled to the hook when the guide protrusion 425 passes over the detergent container arresting part 5392 of the guide recess 539 of the detergent container 500 and is subsequently stopped when the detergent container 500 is inserted into the detergent container receiving unit 420 as described above. Because the hook 426 of the guide protrusion 425 is caught by the detergent container arresting part 5392 of the guide recess 539 , the detergent container 500 , when inserted into the inner side of the housing 421 , will be maintained in a stopped state (held in place).
  • the front panel 400 may have an opening 460 protruding forward from the front panel 400 (in a direction that is toward the front surface of the cabinet 100 ) and having an annular shape.

Because the annular end portion 462 has a diameter smaller than that of the opening 460 and protrudes from the end portion of the opening 460 , the annular end portion 462 has a step-like surface that is perpendicular to the direction from which the annular end portions 462 protrudes.
  • the door gasket 450 When the door gasket 450 is installed in the opening 460 , the door gasket 450 may receive a relatively high supporting force due to the annular end portion 462 of the opening portion 460 and the step-like surface.

  • the guide hole 429 is disposed on a lower surface of the detergent container receiving unit 420 , and the lower surface of the detergent container receiving unit 420 may be separated from the case 530 of the detergent container 500 by a gap when the detergent container 500 is inserted into the detergent container receiving unit 420 . Due to the difference in height therebetween, the guide hole 429 for discharging wash water from the first outlet 5332 and the second outlet 5352 to the tub 700 is formed.
  • the guide rib 452 serves to guide washing water from by the guide hole 429 to the tub 700 .
  • the guide rib 452 may be positioned behind a rearmost end of the door glass 280 in the door 200 .

  • wash water discharged from the first overflow part 5337 and the second overflow part may be discharged directly to the tub 700 , without passing through the guide hole 429 and the guide rib 452 . Due to the presence of the guide ribs 452 , the detergent or conditioner dissolved in the wash water may be prevented from being applied to the door glass 280 .
  • the wash water discharged through the first siphon section S 1 or the second siphon section S 2 may be discharged to the guide hole 429 , and the wash water discharged to the guide hole 429 may be guided to the inner side of the tub along the guide rib 452 .
