Namely whether reach the highest dehydrating speed such as 700 revs/min, if so, then enter step S500, if otherwise enter step S600.
S500, long de-.
S600, control dehydration electric motor reduction of speed and carry out spray intake and draining to defoam.
And after the 3rd Preset Time, entering step S700, the 3rd Preset Time can set as the case may be.
S700, a de-n.
N be greater than 1 natural number, i.e. circulation S600 and de-between carrying out, and return step S400, until judge that the rotating speed of dehydration barrel reaches maximum dehydrating speed.
Put it briefly, the dewatering control method for washing machine of the embodiment of the present invention, lengthen de-process optimize further de-between original, between increase the length of short time in de-process and take off, then dehydrating speed testing process is increased, if the rotating speed of dehydration barrel can reach the highest dehydrating speed namely carry out normal dehydration with regard to directly running, if the highest dehydrating speed of setting cannot be reached, between de-process stop, and reduce the rotating speed of dehydration barrel, spray waterside draining is carried out to remove the foam between interior outer barrel in limit simultaneously, between again starting after a certain time, de-lengthening takes off operation, this process that circulates is until the rotating speed of dehydration barrel can reach the highest dehydrating speed.
