  • the washing machine further includes a circulation tube communicatively connecting the bottom side with the side of the water tub opening, for circulating washing water in the water tub from the bottom side to the side of the water tub opening; and a plurality of ejection holes for ejecting washing water circulated through the circulation tube, toward the inside of the rotating drum.
  • This configuration allows washing water circulated to be ejected toward the inside of the rotating drum through the plurality of ejection holes, thereby feeding the washing water efficiently as well as increasing washing power of the drum type washing machine.

With this configuration, washing, rinsing, and spin-drying steps are performed. Further, drum type washing machine 1 performs a drying step with dryer unit 9 provided as required.
  • Circulation tube 16 is provided to communicatively connect the bottom side of water tub 3 with the side of water tub opening 13 (described later). Washing water retained in water tub 3 circulates from the bottom side of water tub 3 to the side of water tub opening 13 through circulation tube 16.

  • the partial mode is a drive mode in which rotating drum 4 repeats rapid partial rotations by 90 to 180 degrees in the forward and reverse directions.
  • the continuous mode is a drive mode in which rotating drum 4 continuously rotates and repeats forward and reverse rotations alternately. With the continuous mode, the laundry lifted by rotation of rotating drum 4 repeats the behavior of falling due to its self weight; and again being lifted by rotation of rotating drum 4. In a washing step or washing and rinsing step, the partial and continuous modes are executed alternately.
  • the laundry In the forward/reverse partial rotation drive mode, the laundry is lifted by 90 to 180 degrees, and after that the laundry peels off from the inner surface of rotating drum 4 due to an inertial force or the self weight.

  • opening distance D4 is a distance of the opening of the other discharge outlet 55da in the direction perpendicular to the circumferential direction.
  • FIGs. 15A and 15B different opening angles of the right and left discharge outlets about rotation center Q of rotating drum 4 allow changing the directions in which washing water is ejected from right and left ejection holes 53.
  • Washing water ejected from ejection holes 53 through discharge outlet 55da is ejected in the direction of arrow E, which is defined as opening direction E.
  • An angle formed by line segment Qd connecting the opening of discharge outlet 55da to rotation center Q of rotating drum 4; and opening direction E is defined as an opening angle. Accordingly, the opening angle of discharge outlet 55d in FIG. 15A is zero; the opening angle of discharge outlet 55db in FIG.
  • washing water ejected from ejection holes 53 through discharge outlet 55d is ejected in the direction of arrow F, which means that opening direction is F. Opening direction F is equal to the direction of rotation center Q of rotating drum 4, and thus the opening angle is zero. Meanwhile, washing water ejected from ejection holes 53 through discharge outlet 55db is ejected in the direction of arrow G, which means the opening direction is G. Opening direction G forms angle k with the direction of rotation center Q of rotating drum 4, and thus the opening angle is k. In this embodiment, washing water is ejected in the direction of arrow G by providing guide 67 at the front end of discharge outlet 55db. In other words, an opening direction and an opening angle can be set by changing the shape of the front end of a discharge outlet.
  • guide surfaces 57, 56, and 57 respectively corresponding to discharge outlets 55d, 55da, and 55db are formed circularly centering on rotation center Q of rotating drum 4. Accordingly, the cross-section shapes of guide surfaces 56 and 57 are the same with respect to rotation center Q.
  • washing water flowing along guide surfaces 56 and 57 is sharply curved in the direction toward rotation center Q of rotating drum 4, and is more gently curved farther away from the direction toward rotation center Q of rotating drum 4. Consequently, washing water that has been ejected toward rotation center Q of rotating drum 4 and has passed through discharge outlet 55d is ejected in a roughly symmetric shape, with a relatively narrow diffusion angle.
  • washing water that has been ejected upward deflected by angle j with respect to rotation center Q of rotating drum 4 and has passed through discharge outlet 55da; and washing water that has been ejected upward deflected by angle k with respect to rotation center Q of rotating drum 4 and has passed through discharge outlet 55db are ejected with a large diffusion angle.
  • Rib 68 is provided near discharge outlet 55d inside water duct 55b in a direction interfering with the flow of washing water. Rib 68 is formed by projecting a part of cover 55. Rib 68 is large enough to block approximately 50%, for example, of the cross-sectional area of the flow path of water duct 55b.
  • washing water that has flown to water duct 55b through circulation tube 16 has a velocity component in the direction same as the longitudinal direction of water duct 55b when discharged from discharge outlet 55d.
  • the velocity component causes the washing water to be ejected deflected in the longitudinal direction of water duct 55b with respect to the direction from discharge outlet 55d and guide surface 56 toward rotating drum 4.
  • rib 68 provided, washing water that has flown through water duct 55b collides with rib 68, which counteracts the above-described longitudinal velocity component of the washing water, resulting in being ejected along the direction from discharge outlet 55d and guide surface 56 toward rotating drum 4.
  • the washing water is ejected in a direction according to those of discharge outlet 55d and guide surface 56.
  • rib 68 can be provided near discharge outlets 55da and 55db inside water duct 55b.
  • a drum type washing machine of the present invention feeds washing water with an optimum ejection angle and a diffusion angle regardless of the amount of the laundry, and thus is applicable to a washing machine with a rotating drum.
