When carrying out laundry operations, at first washings is put in the swing roller 5 input operation sign on then.After the operation beginning, control module 16 is read control program from memory cell 18, and begins to carry out control operation with following control procedure.
At first, control module 16 rotates swing roller 5, detects by 12 pairs of washings amounts of clothes quantity detecting device.Clothes quantity detecting device 12 detects the washings amount from the drive motors 7 suffered load variations relevant with the washings amount, and detected washings amount is imported in the control module 16, stores in the memory cell 18 again.
Next, control module 16 is opened water intaking valve 11, outwards adds running water in the bucket 6.When the water level outside water level detecting unit 14 detects in the bucket 6 has reached the predetermined water level of determining according to the washings amount, then send signal, make water intaking valve 11 shut-down operations (fastening) to control device 15.Because outer bucket 6 and swing roller 5 are downward-sloping on being provided in from the face side of body 1 to the direction of rear side,, the washings that add stockpile near the intersection between the inner surface of the inner surface of exterior bowl ladle body part 2b and exterior bowl bucket bottom branch 2c and the state below being positioned at so will being in.
Afterwards, enter washing stroke.Drive swing roller 5 by motor 7 and rotate, along with the rotation of the fin 38 on the fin installing component 37 that is installed in the swing roller 5, the direction that washings are begun shown in the arrow A of Fig. 3 is played (pump rises).When the rotary speed of swing roller 5 meet or exceed predetermined rotational speed, in the time of also can making washings be adjacent to rotary speed (for example 80 rev/mins) on the inner surface of swing roller 5, washings divide near the intersection between the 2c and rotate beginning to accumulate in exterior bowl ladle body part 2b and exterior bowl bucket bottom under action of centrifugal force.
Here, owing to be provided with outer wall 40 in the fin installing component 37, taken up by fin 38 and can run into earlier on the outer wall 40 that is located in the fin installing component 37 at the dirty washings of action of centrifugal force to exterior bowl ladle body part 2b one side, and flowing to the exterior bowl bucket bottom that is provided with intake 20 along outer wall 40 like that and divide 2c one side shown in the arrow B of Fig. 7.
At this moment, washings not only flow to exterior bowl bucket bottom and divide 2c one side, also rotate near the boundary of exterior bowl ladle body part 2b and exterior bowl bucket bottom branch 2c simultaneously.Because exterior bowl bucket bottom divides 2c to be provided with diversion recess 21,, flow in the 1st circulation water channel 22 through intake 20 again so washings are directed to the diversion recess 21 under the effect of impulse force that flows out from fin installing component 37 and gravity.
Thereafter, the washings of inflow arrive in the circulation nozzle 34 through the 2nd circulation water channel the 26, the 3rd circulation water channel 27 and the 4th circulation water channel 28.Because it is circular-arc that the 1st circulation water channel 22 is arranged to, thus the mobile of washings can not hindered, thereby can form washings current smoothly.

Fall washings on the washings in infiltrating washings after, be discharged to outside the swing roller 5 from the many through holes that are located on the swing roller 5 under the action of centrifugal force when rotated, turn back to again in the outer bucket 6.
So, washings are penetrated in the washings soon.
Here, because being located at the first half of exterior bowl bucket bottom branch 2c and being positioned at washings, diversion recess 21 and intake 20 rotate mobile downstream one side, therefore except the impulse force when intake 20 flows into, also can add the effect of gravity in the washings in the 1st circulation water channel 22, make the washings current become very strong.Like this, the washing water yield that sprays from water jet can increase, and washings are sprayed onto on the large-scale washings.
In addition, intake 20 and diversion recess 21 are located at the words of downstream one side of washings current, compare with the occasion that is located at upstream one side and can shorten the 1st circulation water channel 22, reduce manufacturing cost, reduce the resistance that is subjected to when washings pass the 1st circulation water channel 22 simultaneously.In addition, can be longer owing to be subjected to the time of the power that the rotation of swing roller produces, the washings impetus of being introduced by intake 20 can be stronger.
In addition, because water jet 32 is located at than on the low position of intake 20, the hydraulic pressure of water jet 32 1 sides that produced by the difference of height (potential head) between intake 20 and the water jet 32 can improve, therefore, the impetus of the washings of discharging can strengthen, and circular flow also can increase.Simultaneously, after the impetus of the washings of ejection increases, can spray more large-area washings in the swing roller 5 and go up washings.
Thereafter, the rotation of swing roller 5 is suspended, carry out " beaing " washing then, that is to say, make swing roller 5 catch on, mention, arrive the rotary speed of throwing again behind the suitable height along direction of rotation and be rotated can make washings be arranged on stirring thrust 5e on the inner surface of swing roller 5.Make recited above the washings that stockpile in the bucket 6 outside swing roller 5 inner circulations by resembling, make washings under the state that has fully permeated washings, knock washing, therefore, compare with the inadequate occasion of the infiltration of washings, not only cleaning performance can be improved, but also the cleaning uneven phenomenon can be reduced.In addition, produce the required time of identical cleaning performance also will shorten, can also produce the effect that shortens wash time thus.
In addition, though the position of the intake 20 in the present embodiment as shown in Figure 3 be positioned at the downstream that exterior bowl bucket bottom is divided the first half of 2c and is arranged on the rotary water current of washings like that, but, as long as can get when swing roller 5 rotations outside and be rotated washing water flowing in the bucket 6, also can spray from water jet 32, the position of intake 20 also is not limited to above-mentioned position.
