Definitions

  • the present invention relates to a drum type washing machine including a filter unit for trapping particles, such as lint, contained in discharged water.
  • Fig. 4 is a cross-sectional view of conventional drum type washing machine 501 disclosed in Japanese Patent Laid-Open Publication No. 2001-104690 .
  • Washing machine 501 includes housing 20, water tub 204 supported in housing 201, rotatable drum 205 rotatably accommodated in water tub 204, drain passage 211 for discharging the washing water stored in water tub 204, drain pump 210 provided at a downstream of drain passage 211, drain hose 227 for discharging washing water through drain pump 210, and filter 220 provided between drain passage 211 and drain pump 210. Drain passage 211 is located below water tub 204.
  • Filter 220 has arms 221 for trapping particles, such as lint, contained in the discharged washing water.
  • Filter 220 trapping the particles prevents the clogging of drain pump 210, drain passage 211, and a drain pipe line communicating with a sewage system of a house in which washing machine 501 is installed.
  • washing water When a laundry is washed by washing machine 501, washing water always fills a portion from water tub 204 to drain pump 210 and drain hose 227. Drain hose 227 extends from the lower part of housing 201 to the upper part of housing 201, hence preventing the washing water from being discharged during the operation of the washing machine. The particles trapped by filter 220 cannot be removed during a washing process. If filter 220 is taken out during the washing process, the washing water leaks from a part from which filter 220 is taken out.
  • Fig. 5 is a perspective view of another conventional washing machine 502 disclosed in Japanese Patent Laid-Open Publication No. 2002-282616 .
  • Washing machine 502 includes housing 112, cover 101 provided at a right-rear side of the front of housing 112, and filter unit 503 provided in cover 101. Cover 101 can be opened and closed.
  • Fig. 6 is an enlarged perspective view of washing machine 502 having cover 101 opened.
  • Cover 101 can be formed by molding resin material.
  • a lower end of cover 101 is pivotally supported by housing 112.
  • An upper end of closed cover 101 moves about the lower end in direction F.
  • Rib 102 extending slantingly and hook 103 protrude from a back surface of cover 101.
  • Cap 106 is provided inside cover 101 to take out filter unit 503 from housing 112 and to attach unit 503 to housing 112.
  • Cap 106 is unitarily formed with handle 106B for rotating cap 106.
  • Filter unit 503 includes a filter for trapping particles. Upon cap 106 being rotated to loosen cap 106, the filter having particles trapped thereon is taken out from the filter unit. Then, the filter is cleaned to remove the particles. Then, the filter is returned into the filter unit. Then, cap 106 is tightened to its original position, thereby preventing water from leaking from a periphery of cap 106.
  • Fig. 7 is a front view of the filter unit of washing machine 502.
  • cover 101 is properly closed. Specifically, in the case that angle ⁇ between the horizontal direction and a direction along which handle 106B extends is substantially 90 degrees, cover 101 can be closed completely in direction F shown in Fig. 6 while preventing rib 102 of cover 101 from contacting handle 106b of cap 106, as shown in a broken line of Fig. 7 , thereby preventing the water from leaking. At this moment, a tip of hook 103 is engaged with engagement hole 104 to prevent cover 101 from easily opening.
  • angle ⁇ of handle 106B is not 90 degrees and when cover 101 is rotated in direction F, rib 102 contacts handle 106B to prevent cover 101 from being closed. Since cover 101 cannot be closed, a user can recognize that cap 106 is incompletely tightened. Then, the user can operate handle 106B again to rotate cap 106 until cap 106 reaches a proper position, thereby preventing the water from leaking. Specifically, the user can determine whether cover 101 is properly attached to housing 112 or not, thus preventing the water from leaking.
  • washing machine 502 may cause the user to forget to close cover 101. In this case, the user cannot determine whether the water is prevented from leaking or not.
  • Washing machine 502 includes cover 101 preventing the number of components from decreasing.
  • Cover 101 is generally formed by molding resin material. Cover 101 is generally provided at the lower part of housing 112. Thus, a toe of a person may collide with cover 101 when the person passes by washing machine 502. The user may forcibly close cover 101 without recognizing that cap 106 is improperly tightened. In these cases, cover 101 may be damaged or removed from housing 112, and thus, the user cannot determine whether the water is prevented from leaking or not.
  • Washing machines 501 and 502 are operated by the user who is not an expert, and hence, easily preventing the water from leaking.
  • a drum type washing machine includes a rotatable drum adapted to store a laundry, a drain valve, a drain pump, a controller, and a filter unit.
  • the filter unit includes a filter case provided between the drain valve and the drain pump, a filter accommodated in the filter case, a cap for sealing a fixing opening, and a reed switch.
  • the reed switch is activated to outputs an activation signal to the controller when the cap is located at the predetermined position, and deactivated to output a deactivation signal to the controller when the cap is not at the predetermined position.
  • the controller is operable to, when determining that the reed switch outputs the deactivation signal while executing a process out of the washing process and the rinsing process, stop the process.
  • the controller is operable to, when determining that the reed switch outputs the deactivation signal while executing the draining process, stop the draining process, close the drain valve, and drive the drain pump.
