Control method of dual-drum washing machine

Abstract

A control method of a dual-drum washing machine, comprising the following steps: step S 1 : before a first washing drum performing heating; step S 2 : determining whether a second washing drum is heating; step S 3 : if the determination result is yes, determining whether the remaining heating time of the second washing drum is more than T 0 ; and step S 4 : if the determination result is yes, performing an alternate heating procedure in which the first washing drum and the second washing drum heat alternately, and if the determination result is no, performing a sequential heating procedure in which the second washing drum heats before the first washing drum, wherein T 0 is a time value, set through a system, for determining whether heating of the second washing drum is coming to an end.

1 . A control method of a dual-drum washing machine, comprising following steps:
 step S 1 : before a first washing drum performing heating;   step S 2 : determining whether a second washing drum is heating;   step S 3 : if yes, determining whether a remaining heating time of the second washing drum is more than T 0 ;   step S 4 : if yes, performing an alternate heating procedure in which the first washing drum and the second washing drum heat alternately, and if no, performing a sequential heating procedure in which the second washing drum heats before the first washing drum does,   wherein T 0  is a time value, set through a system, for determining whether heating of the second washing drum is coming to an end.   
     
     
         2 . The control method of a dual-drum washing machine according to  claim 1 , wherein a total heating time of the second washing drum is T m2 , and 0<T 0 ≦⅓T m2 . 
     
     
         3 . The control method of a dual-drum washing machine according to  claim 1 , wherein 0<T 0 ≦5 min. 
     
     
         4 . The control method of a dual-drum washing machine according to  claim 1 , wherein in the alternate heating procedure of step S 4 , the first washing drum and the second washing drum alternately heat for certain time intervals;
 after the end of heating for each time interval, whether heating of the first washing drum and the second washing drum ends is determined; if heating of the first washing drum or the second washing drum ends, the second washing drum or the first washing drum keeps heating until the end; and otherwise, alternate heating is continued.   
     
     
         5 . The control method of a dual-drum washing machine according to  claim 1 , wherein in the alternate heating procedure of step S 4 :
 after the time interval of heating of the first washing drum reaches T 1 , whether a temperature of the first washing drum is equal to a preset temperature is determined;   if yes, heating of the first washing drum ends, and the second washing drum heats up to the preset temperature; and if no, heating of the first washing drum pauses, and the second washing drum heats; and   after the time interval of heating of the second washing drum reaches T 2 , whether a temperature of the second washing drum is equal to the preset temperature is determined; if yes, heating of the second washing drum ends, and the first washing drum heats up to the preset temperature; and if no, heating of the second washing drum pauses, and the first washing drum heats.   
     
     
         6 . The control method of a dual-drum washing machine according to  claim 5 , wherein T 1  and T 2  are minimum time intervals for each heat time of the first washing drum and the second washing drum, respectively. 
     
     
         7 . The control method of a dual-drum washing machine according to  claim 1 , wherein in the sequential heating procedure of step S 4 , the first washing drum waits until the end of the heating of the second washing drum, and then to heat, and the second washing drum executes following determination during heating:
 whether a temperature of the second washing drum is equal to a preset temperature; if yes, heating of the second washing drum ends; and if no, heating of the second washing drum does not end.   
     
     
         8 . The control method of a dual-drum washing machine according to  claim 7 , wherein the first washing drum executes following determination during heating:
 whether a temperature of the first washing drum is equal to the preset temperature; if yes, heating of the first washing drum ends and a heating phase ends; and if no, heating of the first washing drum does not end.   
     
     
         9 . The control method of a dual-drum washing machine according to  claim 1 , wherein if the determination result is no in step S 3 , executing following determination:
 whether the second washing drum is performing any of a dewatering or a drying procedure is determined; if yes, the first washing drum waits until the corresponding dewatering or drying procedure of the second washing drum is finished, and then to heat; and if no, the first washing drum heats.   
     
     
         10 . The control method of a dual-drum washing machine according to  claim 1 , wherein the first washing drum is independently provided with a first heating device for heating the first washing drum, and the second washing drum is independently provided with a second heating device for heating the second washing drum; and
 the first washing drum and the second washing drum are provided therein with a first sensor and a second sensor for monitoring a temperature of washing water, respectively.   
     
     
         11 . The control method of a dual-drum washing machine according to  claim 2 , wherein 0<T 0 ≦5 min. 
     
     
         12 . The control method of a dual-drum washing machine according to  claim 6 , wherein, T 1 =T 2 .
