    • A washing machine control method reduces washing time and component stress from a repetitious re-supplying of water, due to absorption and evaporation after an initial supplying of water according to a selected wash course, by determining an optimum water re-supply amount according to a water level reduction rate. The method includes steps of proceeding a user-selected wash course for a predetermined time after supplying water to a washing machine according to a first water level set based on an amount of laundry in the washing machine; sensing a second water level corresponding to the predetermined time of the wash course; calculating a water level reduction rate based on the set first water level and the sensed second water level; determining an optimum water re-supply amount by comparing the calculated water level reduction rate to a predetermined value; re-supplying the water according to the first water level, if the calculated water level reduction rate is less than the predetermined value; re-supplying the water according to a third water level, greater than the first water level, if the calculated water level reduction rate is not less than the predetermined value; and completing the user-selected wash course after re-supplying water to the washing machine according to the optimum water re-supply amount. The sensing and calculating steps may each be repeated, say, three to four times, to obtain an average rate of water level reduction, so that the user-selected wash course may be reset based on the average rate of water level reduction.
    • 洗衣机控制方法通过根据选择的洗涤过程在初始供水之后由于吸收和蒸发而重复地重新供应水的洗涤时间和组分应力,通过根据所选择的洗涤过程确定最佳的供水量 水位降低率。 该方法包括以下步骤:根据基于洗衣机中的衣物量设定的第一水位,向洗衣机供水之后,进行用户选择的洗涤过程一段预定时间; 感测对应于洗涤进程的预定时间的第二水位; 基于设定的第一水位和感测到的第二水位计算水位降低率; 通过将计算出的水位降低率与预定值进行比较来确定最佳的供水量; 如果计算出的水位降低率小于预定值,则根据第一水位重新供水; 如果所计算的水位降低率不小于预定值,则按照大于第一水位的第三水位重新供水; 并根据最佳的供水量向洗衣机重新供水后完成用户选择的洗涤过程。 感测和计算步骤可以各自重复,例如三到四次,以获得平均水位降低率,从而可以基于平均水位降低率重新设定用户选择的洗涤过程。
