Abstract: A water replenishment control method for a multi-drum washing machine. The washing machine comprises at least a first washing drum and a second washing drum. While the first washing drum is in a washing process, if the water level of washing water is lower than a set value, then a water replenishment process is executed, and before that, it is necessary to determine whether or not the second washing drum is executing a water replenishment process; if yes, the first washing drum pauses the water replenishment process, and the second washing drum executes precedence preferentially; if no, the first washing drum executes water replenishment process and terminates it when the water level of the washing water reaches a set water level.

Abstract: A control method of a double-drum washing machine, having a first washing drum and a second washing drum. Whether the heating time required by the first drum is overlong is judged before the first drum performs heating. If yes, the second drum executes the heating, or dewatering, or drying processes. If not, the following steps are performed: judging whether the second drum performs heating; if yes, judging whether the remaining heating time of the second washing drum is greater than T0; if the judgment result is yes, executing the alternate heating program that the first drum and the second washing drum perform heating alternately, and if the judgment result is no, executing the ordered heating program that the second drum performs heating firstly, and then the first drum performs heating, wherein T0 is a time value for judging whether the heating of the second drum is about to finish or not.

Abstract: A washing machine comprises a first washing drum with a first heater and a second washing drum with a second heater. Before the first washing drum performs a heating procedure, it is necessary to determine whether the second washing drum is performing the heating procedure; if not, the first washing drum performs the heating procedure; if yes, it is necessary to determine whether the remaining heating time of the second washing drum is less than a set value, T min; if yes, the first washing drum pauses the heating procedure; when the second washing drum finishes performing the heating procedure, the first washing drum then performs the heating procedure; if not, remaining heating time of the first washing drum and that of the second washing drum are determined, whichever drum having the shorter remaining heating time performs the heating procedure first, while the other drum performs the heating procedure second.

Abstract: A double-drum washing machine has a first washing drum and a second washing drum. A control method comprises water intake and drainage control and high-power process control, wherein the water intake and drainage control comprises water intake control and water drainage control; the first washing drum judges whether to reuse drained water of the second washing drum before executing a water intake process and judges whether to enable the drained water to be drained into the second washing drum and reuse the water or not before executing a water drainage process; and the high-power process control is used for controlling any one of a heating process, a dewatering process and a drying process of the first washing drum and any one of a heating process, a dewatering process and a drying process of the second washing drum not to be executed at the same time.
