In the wash time of setting (for example 15 minutes) described the 1st stirring control operation is carried out, made washings carry out the effect that place-exchange is washed while can play.But,, can reach better effect if after the 1st stirring control operation of having carried out a period of time, carry out the 2nd again and stir control operation.
Stir in the control operation the 2nd, driving swing roller 5 in the 3rd stipulated time (as 7 seconds) earlier is rotated in the forward with the 2nd regulation rotary speed (as 45～90 rev/mins), afterwards, the driving of in the 4th stipulated time (as 4 seconds), stopping the rotation, then, carry out reverse drive in the 3rd stipulated time on the 2nd regulation rotary speed, last, the driving of in the 4th stipulated time, stopping the rotation.Such control operation constitutes a circulation, carries out repeatedly in the time of setting (as 1 minute).
Under the 2nd above-mentioned regulation rotary speed, under the centrifugal action that produces when swing roller 5 rotations, washings can be adjacent on the internal face of swing roller 5.By washings is adjacent on the internal face of swing roller 5, is block washings and can be extended into deployed condition.When the rotation driving was stopped, the washings that forwards swing roller 5 tops to can separate, fall with the internal face of the swing roller that is rotating 5 along with inertia.By carrying out such motion that is adjacent to, stretches and fall, in the washings occurrence positions to be moved and change of shape, the effect of knocking washing is also more effective.
Stir the mutual control operation of carrying out of control operation by in the time of setting (between), carrying out the this 1st and the 2nd constantly as 15 minutes, the front and back position of washings in swing roller 5 will exchange, simultaneously, can not take place to cause cleaning performance to descend, but can be applied with uniform cleaning action all washings because of the motion mode difference of knocking when washing and swing roller 5 are inclined to set.
After above-mentioned washing operation is finished, control module 11 will be opened the control instruction of draining valve 27 to power switch unit 12 output, carry out the draining control operation that washings dirty in the steel ladle 3 are discharged.Then, thereby control module 11 is exported the control instruction that makes drum drive motor 4 high speed rotations that washings contained in the washings are dewatered in power switch unit 12, thereby carries out dehydrating operations after washing operation.
After dehydrating operations has carried out official hour, control module 11 will be closed draining valve 27, open water intaking valve 26, add new water in steel ladle 3, begin to carry out the rinsing operation.In the rinsing operation, also drive the rotation that swing roller 5 is made positive and negative direction, carry out stirring operation.Stir control operation and/or the 2nd and stir control operation by carrying out the identical with above-mentioned washing operation the 1st, the washings occurrence positions is exchanged, make and knock clean result and affact equably on all washings, can eliminate the rinsing uneven phenomenon.
After the rinsing operation of having carried out the stipulated time, carry out dehydrating operations again.So far, all laundry operations processes finish.Control module 11 sends the notice that laundry finishes, while power cutoff switch 18, end operation.
Though what illustrate in the above embodiments is the structure that swing roller 5 is obliquely installed,, above-mentioned water level detecting mechanism swing roller be arranged to horizontal direction occasion under equally also be suitable for.
