Step S108
If the washing time of setting finishes, the rotation that then finishes the swing roller 3 that drum drive motor 4 produced drives, and opens drain solenoid valve 12 to discharge the flushing water in the water receiving tank 2.
Step 401
If the draining of flushing water finishes, then index drum drive motors 4 drives swing roller 3 and begins contained flushing water in the centrifugal washings of deviating from the swing roller 3 to rotate with middle dehydrating speed under the state of opening drain solenoid valve 12.Be rotated and drive so that the rotating speed of the swing roller 3 of this moment becomes the rotating speed that the resonance speed (180-250rpm) of resonance takes place above swing roller 3.

Step S109
Carry out the centrifugal dehydration of flushing water.
But this type of tumbling-box washing machine efficient realizes drifting out of washings contained detergent ingredients (flushing water) well.
Illustrate when dehydration is rotated by the raising that sprays the caused rinsing performance of watering according to Figure 22 and Figure 23.
The desirable use amount of commercially available powder detergent is 20 grams for 30 liters of flushing waters.Though the washing water yield is set at the flushing water of 30 liters tumbling-box washing machine and how much is all 30 liters regardless of washings cloth amount, when washings cloth amount is big, be not enough to play the decontamination of washing agent, so the big more detergent amount of washings amount is big more with 20 gram washing agent.For example, in the upright type washing machine that with the washing and dewatering groove that is equivalent to swing roller is the longitudinal axis and rotation, the desirable washing water quantity of washing 8kg clothing is 60 liters, and the desired detergent amount is 40g.So, in this tumbling-box washing machine, wash the 8kg washings by dropping into desirable 40g washing agent, can make washing agent fully act on the spot of washings to clean.
But, owing to finish to contain the high flushing water of detergent concentration in the washings of flushing, think the detergent ingredients of this flushing water is fully drifted out and necessary rinsing repeatedly, so weakened the water-saving result of tumbling-box washing machine.
But the tumbling-box washing machine among this embodiment 5 drifts out detergent ingredients well by spray clear water efficient in centrifugal operation of sloughing flushing water.As shown in figure 22, though by spraying clear water and increased the consumption of running water pipe water, have the effect that significantly reduces contained detergent ingredients concentration in the washings in the spray water of from wash the flushing water dehydration procedure of operation when forwarding rinsing process to, carrying out.In Figure 22, " storage rinsing " is not carry out spray water and in centrifugal mode of carrying out rinsing process after sloughing flushing water, and " spray water+storage rinsing " is that the waterside is sprayed in centrifugal mode of carrying out rinsing process after sloughing flushing water in the limit.
The concrete washing water yield is for example shown in Figure 23, even add 6 liters spray water, carry out three rinsings then 126 liters get final product, carry out twice rinsing then 96 liters get final product.Therefore, need carry out rinsing process so that in the washings detergent ingredients of contained washings be below the 30ppm, with " storage rinsing " thus mode because the consumption that need carry out three rinsing washings is 120 liters, relatively, with " spray water+storage rinsing " mode since carry out twice rinsing can think 96 liters consumption, as a result, can realize water saving.
