过滤组件 9清洗完毕后， 进入衣物洗涤程序， 衣物洗涤预设时长后， 浊 度传感器 2检测洗涤筒 3内的洗涤液的浊度，如果浊度检测值小于预设阈值， 则开启水泵 4、第二阀门 6以及第二三通阀 12至洗衣机洗涤筒 3，洗涤液经 水泵 4进入粗过滤器 8进行粗过滤，之后通过第二阀门 6进入过滤组件中进 行精过滤， 实现洗衣用水的净化， 净化后的洗涤液经第二三通阀 12流回洗 涤筒 3进行循环使用； 如果洗涤液的浊度大于预设阈值， 则开启第一三通阀 5将洗涤液排出洗衣机外。
此外，本实施例所述的洗衣机还包括用于检测过滤组件 9两端压力值的 压力传感器（图中未示出） ， 用于检测过滤组件 9两端的压力值， 该压力值 用于判断过滤组件是否产生污堵，具体过程可参见用于洗衣机的控制方法实 施例。
本发明提供的洗衣机及其控制方法，可及时清理过滤组件的滤膜上拦截 的污物，避免了因污物的长期残留造成过滤组件清洗困难， 有利于延长过滤 组件的使用寿命， 降低洗衣机的维护成本。
在本发明上述各实施例中， 实施例的序号仅仅便于描述，不代表实施例 的优劣。 对各个实施例的描述都各有侧重， 某个实施例中没有详述的部分， 可以参见其他实施例的相关描述。
