In some embodiments of the invention, turning between the stopping time in strong current washing step is: rotational time is 3 ~ 5S, dwell time is 2 ~ 3S.The rotation order of impeller can be set as rotating forward, stops, reversing, stop; Namely impeller first rotates forward 3 ~ 5S fast, washings are driven also to rotate forward fast, atwirl washings apply the impulsive force of direction of rotation to actionless bucket wall, namely atwirl washings and bucket wall friction, apply larger power to the dirt on bucket wall; Impeller stops 2 ~ 3S afterwards, and washings continue forward fast rotational due to inertia, wash away bucket wall; Impeller reverse quick rotation 3 ~ 5S more afterwards, washings have the trend rotated forward and the trend under impeller effect with reverse rotation under effect of inertia, washings are made to form larger whirlpool, whirlpool is beaten on bucket wall, apply power from multiple directions to dirt, the reverse fast rotational of impeller followed by washings afterwards; Impeller stops 2 ~ 3S more afterwards, and washings continue reverse fast rotational due to inertia; Enter a circulation afterwards, impeller rotates forward again, and washings have the trend of reverse rotation and under impeller effect, have the trend rotated forward under effect of inertia, makes washings form again larger whirlpool, washes away a barrel wall; So be cycled to repeat, the dirt sticked on barrel wall is come off.
Through test of many times research, the wash time of strong current washing step is within 2 ~ 4 minutes, just to make the dirt sticked on barrel wall come off.In the present embodiment, the wash time arranging strong current washing step is 3 minutes.
Drain step: draining valve is opened and made washing of drum type washing machine water sport, washings are discharged; Drain shut valve afterwards, the clean barrel knot bundle of washing machine.In the present embodiment, in drainage procedure, washing machine washed water is in the state of motion, increases washings to the impact of bucket wall, the dirt swum in washings both can have been avoided again to be applied on barrel wall, the dirt do not come off can also be made to come off.Make the bucket wall of washing machine totally cleaned like this, improve the clean-up performance of washing machine drum.
In some embodiments of the invention, in drain step, make washing of drum type washing machine water sport, can impeller or inner cylinder rotating be passed through, drive washings motion; In the present embodiment, impeller and inner core synchronous rotary drive the motion of washing machine washed water; Drain step arranges step, platoon step and used row's step between comprising successively.By setting gradually different dehydration, the dirt swum in washings is mainly avoided again to be applied on barrel wall.
Between arrange step: motor drives impeller and the synchronous alternate intervals of inner core to rotate.Impeller and inner core can be arranged rotate according to the circular order rotating forward, stop, wherein arrange that rotational time is 5 ~ 6S, dwell time is 2 ~ 3S, by impeller and inner core synchronous rotary, also arrange than rotational time longer in strong current washing, the washings in washing machine are made to form stronger current under impeller and inner core drive, form larger whirlpool, make washings larger to the impulsive force of bucket wall, avoid the dirt swum in washings and be again applied on barrel wall.In addition, washings are larger to the impulsive force of bucket wall, and the frictional force in other words between washings and static outer barrel is larger, make do not have the tough stains departed to come off, improve the clean bucket cleannes of washing machine further.In this step, motor drives impeller and inner core synchronously alternately to rotate in the same way.
Between arrange step dewatering time be set to 0.5 ~ 2 minute, the dewatering time arranging step between preferably arranging is 1 minute.
Platoon step: motor drives impeller and the synchronous continuous rotation of inner core.Connecting the de-time is 0.5 ~ 2 minute, and preferably the company of setting is 0.5 ~ 2 minute the de-time.Because in row's step, portion of washing water is got rid of, the load of washing machine is less, impeller and inner core can high-speed synchronous continuous rotations, remaining washings in washing machine are made also to follow High Rotation Speed, washings and bucket wall are impacted, especially and there is between static outer barrel wall larger friction, avoid the dirt swum in washings and be again applied on barrel wall; Also make do not have the tough stains departed to come off further, improve the clean bucket cleannes of washing machine.
Used row's step: motor power-off, impeller and interior bucket rely on inertia to continue to rotate.The used de-time is 0.5 ~ 1 minute, and preferably arranging the used de-time is 0.5 minute.Impeller and interior bucket rely on inertia to continue to rotate, and washings are also in High Rotation Speed state, avoid the dirt swum in washings and are again applied on barrel wall.
After the row's of getting used to step, drain shut valve, namely draining valve power-off, simultaneously motor brake, impeller and interior bucket static, clean bucket completes.
In the present embodiment, reduce discharging step discharge section washings by draining, reduce the load of washing machine, make washing machine can enter strong current washing step, increase washings washing away bucket wall, improve the ability of dirt on clean bucket wall.Prove through overtesting, the dirt sticked on barrel wall can be removed totally substantially at strong current washing step, and the dirt be separated with bucket wall swims in washings; Afterwards, washings should be discharged, and in order to avoid the dirt in washings sticks on barrel wall again, pollute the clothing of washing next time; Setting directly enters dehydration after opening draining valve, and the washings in washing machine are kept in motion always, and impact bucket wall, the dirt on such washings can not be applied on barrel wall again, but follows outside washings discharge bucket; In addition, in dehydration, washings are larger to the impulsive force of bucket wall, and the tough stains do not departed from bucket wall is departed from
