⑶, stop to pump into, washing machine inflow is to water level, and the drive unit that computer program controller of washing machine 24 control urceolus bottoms arrange rotates, wash, simultaneously 5 opening times of air pump are carried out timing and judge, if 5 opening times of air pump less than 6min, continue to open air pump 5 so; If 5 opening times of air pump reach 6min, computer program controller of washing machine 24 control air pumps 5 quit work, and this moment, liquid detergent was converted into foam fully;
⑷, dewatering: carry out dewatering work after clothes washing is complete.
Step 3: retaining rinsing program
⑴, retaining rinsing: when immersion after washing procedure finishes, enter rinsing program, computer program controller of washing machine 24 detects whether retaining rinsing, if not then directly carrying out rinsing; If it is the water inlet water level is detected, after the water inlet water level did not have the peristome of bubble generator 16, computer program controller of washing machine 24 control high pressure generators 2 and air pump 5 were started working simultaneously, and timing;
⑵, generation ozone: air pump 5 begins outside air is pumped in the ozonator cell 6, simultaneously the high-voltage corona district occurs to produce between the head by high-voltage line 13 at two ozone of ozonator cell 6 in high pressure generator 2, and the aerobic air of the inside is ionized generation ozone;
⑶: generate and pump into ozone bubbles and air bubble: air pump 5 pumps into bubble generator 16 interior generation ozone bubbles and air bubbles with ozone and the portion of air of ozonator cell 6 interior generations by the wireway 14 that is provided with check valve 15, with fully combination dissolving of washings, carry out sterilization and bleaching work;
⑷: stop to pump into: washing machine inflow is to water level, the drive unit that computer program controller of washing machine 24 control urceolus bottoms arrange rotates, carry out rinsing, before rinsing finishes to carry out draining, computer program controller of washing machine 24 control air pumps 5 and high pressure generator 2 quit work, and stop washing machine urceolus injection of ozone and air;
⑸, dewatering: carry out dewatering work after the clothing rinsing is complete;
⑹ if rinsing program is more than twice or twice, determine whether to repeat as required ⑴～⑸.
Step 4: last dehydration procedure
⑴, at last dehydration: washing machine is detected, whether dewater for the last time, if not then continuing to carry out if it is unlatching high pressure generator 2 in dehydration work, and beginning timing according to step 3;
⑵, generation ozone, high pressure generator 2 passes through high-voltage line 13 at ozonator cell 6 interior generation ozone;
⑶, pump into ozone, ozone enters in the bubble generator 16 by the wireway 14 that is provided with check valve 15, and shunts by bubble generator 16, enters in the washing machine urceolus again, carries out sterilization operation;
⑷, stop to pump into, detect the opening time T2 of high pressure generator 2, if T2=T3-2min(T3 is the time of whole dehydration), computer program controller of washing machine 24 control high pressure generators 2 quit work so, this moment, dehydration procedure continued, if T2 ≠ T3-2 continues to open high pressure generator 2 so, until computer program when detecting T2=T3-2, just stops to open high pressure generator 2;
⑸, dehydration procedure finish: 2min turn-offs ozone before finishing, so that it is residual to remove the ozone that remains on the clothing, the purpose that this section ozone is opened is sterilization.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described just in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
