如申请号为CN2013104509533的发明专利，其公开了一种絮凝洗衣机，包括洗衣机外桶、絮凝单元及过滤单元，通过管路依次将外桶、絮凝单元、过滤单元循环连通，所述的洗衣机还包括一气泵，该气泵分别与絮凝单元和过滤单元连通。本发明利用同一气泵既能将气泵产生的气体输送到絮凝桶中，在絮凝桶内的水中不断产生大量的气泡，使水充分流动起来，以加速絮凝剂与洗涤脏水充分混合，完成絮凝反应；又能在过滤单元清洗过程中，气泵排出的气体输送到过滤容器内，产生的气泡鼓动过滤容器内的水剧烈运动，并产生瞬间冲击力作用于滤网表面，帮助粘附与滤网表面的污垢脱离下来，增强滤网的过滤效果。
又如申请号为CN2013106039320的发明专利，其公开了一种洗衣机的絮凝桶，絮凝桶包括絮凝桶及扣合在絮凝桶的上部开口处的絮凝桶盖；所述絮凝桶上至少设有进水口、回水口、排水口和投放口；所述的絮凝桶盖上设置有进水结构，所述的进水结构包括环形水道，环形水道的底部设有朝向絮凝桶内壁喷水的喷淋孔，环形水道与絮凝桶的进水口相连通。通过上述装置，降低了进水水流对絮凝桶中的絮凝物的冲击作用力，避免絮凝物被冲散现象的发生；实现进水水流对絮凝桶内壁进行冲刷，达到利用进水水流对絮凝桶进行清洗的目的。
但是，上述专利及目前普遍的絮凝洗衣机均采用的使絮凝物上浮的絮凝剂，当絮凝物上浮后，利用回水口、回水泵及回水管路使处理后的洗涤水再次进入外桶，同时由水位传感器检测絮凝桶内的水位，水位一旦达到设定水位约2L时，回水泵停止，将2L水和上浮的絮凝物存留在絮凝桶内，再利用排水口将絮凝物排出洗涤设备外，达到絮凝处理洗涤水的目的。这种方法存在以下不足：
由于絮凝物一直是悬浮在洗涤水的上方，当水完全从回水口或排水口排出后，漂浮在最上方的絮凝物由于没有水的带动容易附着在絮凝桶的桶底，严重时可能导致絮凝物排出困难，因此需要在洗衣机每次工作后进行清洗工作，无形中增加了工作量。
有鉴于此，特提出本发明。
发明内容
针对现有技术的不足，本发明的第一目的在于，提供一种絮凝洗衣机，以使得絮凝过程中生成的絮凝物下沉后再外排，以实现絮凝物排出方便、在絮凝桶中不易留存的目的。
为了实现发明目的，采用如下技术方案：
一种沉降式絮凝洗衣机，其包括对洗涤水进行絮凝处理的絮凝桶，絮凝桶上设有出水口，所述出水口经三通分别与洗衣机外部和洗衣机外桶可控的相连通，以将絮凝处理后的下沉的絮凝物外排、或洁净水向洗衣机外桶回流。
进一步，所述的出水口设于絮凝桶的底部，絮凝桶的底部自外周向排水口方向逐渐向下倾斜设置，使得排水口处于絮凝桶的最低处，以便于絮沉降絮凝物的收集、外排。
进一步，所述的三通由两位三通阀构成，令絮凝桶的出水口与洗衣机外部或洗衣机外桶相连通；
或者三通的两个出口分别经连接管路与洗衣机外部或洗衣机外桶相对应连通，两连接管路上分别设有控制对应出口水流通断的单向阀，
进一步，所述絮凝桶上设有检测絮凝桶内水位高度的水位传感器，以对絮凝过程中洁净水回流节点进行判断。
进一步，絮凝桶上设有两个出水口，两个出水口分别构成絮凝桶的回水口和排水口，回水口经设有回水阀的管路与洗衣机外桶可控的相连通，排水口经设有排水阀的管路与洗衣机外部可控的相连通。
进一步，絮凝桶内设有对水进行搅拌的搅拌结构，所述搅拌结构包括搅拌电机和搅拌叶片，搅拌电机带动搅拌叶片旋转，以搅动絮凝桶中的水流，加快了絮凝反应及絮凝
物沉降的速率。优选的，搅拌结构的搅拌叶片高于下沉后的絮凝物设置，以避免搅拌叶片搅动下沉的絮凝物，造成对静置分层后的洁净水污染情况的发生。
进一步，所述絮凝桶上部一侧设有电机座，电机座上安装有驱动搅拌结构的搅拌电机，所述电机座的底壁与絮凝桶的桶壁一体成型，所述电机座与絮凝桶桶壁连接处为圆弧形。
本发明的第二目的是提供一种如上任一所述絮凝洗衣机的控制方法，以实现对洗衣机絮凝过程的控制，达到絮凝后絮凝物外排、洁净水回流的目的。为实现上述目的，其具体方式如下：
一种沉降式絮凝洗衣机的控制方法，絮凝过程结束前，将絮凝桶中的水静置一定时间，令絮凝过程中产生的絮凝物下沉至絮凝桶底部；絮凝过程结束后，先将下沉至絮凝桶底部的絮凝物外排至洗衣机外部、再将静止的洁净水回流入洗衣机外桶。
进一步，絮凝过程结束后，先将絮凝桶出水口与洗衣机外部相连通，令下沉的絮凝物随出水外排；至絮凝桶内的水位下降设定高度L，再将絮凝桶出水口与洗衣机外桶相连通，令絮凝后的洁净水回流。
进一步，絮凝桶内的水位下降设定高度L所对应的出水量不低于2至3升。优选的，下降设定高度L为依据絮凝桶型号、絮凝剂类别所对应的设定值，以使得絮凝后生成的絮凝物全部外排。
进一步，絮凝桶内的水位下降至0时，絮凝桶停止回水；同时，洗衣机外桶开始补水，至洗衣机外桶内水位达到漂洗设定水位。
进一步，絮凝过程结束后，先将排水阀打开、回水阀闭合，令絮凝桶排水口与洗衣机外部相连通，令下沉的絮凝物随出水外排；至絮凝桶内的水位下降设定高度L，再将排水阀闭合、回水阀打开，令絮凝桶回水口与洗衣机外桶相连通，令絮凝后的洁净水向外桶回流。
优选的，回水口高于排水口设置，以降低下沉絮凝物回流的几率；同时，可在回水结束后，利用絮凝桶内的剩余水对絮凝物进行冲洗。具体过程如下：当絮凝桶内的水位下降至回水口高度时，将排水阀打开、回水阀闭合，令絮凝桶内的剩余水外排，使絮凝桶排水口处残留的絮凝物排出；并在絮凝桶内的水位下降至0时，将排水阀、回水阀均闭合，絮凝桶停止回水。
采用上述技术方案后，本发明具有如下有益效果：
本发明是针对可使絮凝物迅速沉降的絮凝剂而提出的，对絮凝桶的出水方式进行改进，令絮凝桶先与洗衣机外部连通、再与洗衣机外桶连通，使得下沉的絮凝物被完全收集至絮凝桶底部，并随开始的出水外排；并在絮凝物外排后，再向洗衣机外桶回水，令回水中不再含有絮凝物。从而，降低了絮凝物回流入洗衣机外桶的几率。
在絮凝处理过程完成后，令絮凝处理后的洁净水经回水口回流入洗衣机的外桶，以供漂洗使用；还能令絮凝过程中生成的絮凝物下沉至絮凝桶的底部，并直接从絮凝桶底部的排水口外排。
另外，絮凝桶底部设置为自四周向中心处排水口方向逐渐向下倾斜的设置，以方便絮凝物的沉积和排出。
同时，在整个絮凝物外排、洁净水回流过程中，仅需对絮凝桶内水位进行检测，减少了检测值、简化了判断过程，令洗衣机的结构简化、效率提高。
还有，本发明结构简单，方法简洁，效果显著，适宜推广使用。
附图作为本申请的一部分，用来提供对本发明的进一步的理解，本发明的示意性实施例及其说明用于解释本发明，但不构成对本发明的不当限定。显然，下面描述中的附图仅仅是一些实施例，对于本领域普通技术人员来说，在不付出创造性劳动的前提下，还可以根据这些附图获得其他附图。在附图中：

需要说明的是，这些附图和文字描述并不旨在以任何方式限制本发明的构思范围，而是通过参考特定实施例为本领域技术人员说明本发明的概念。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1所示，本发明实施例中，所述的洗衣机，其内设有现有的洗衣机结构，还设有循环水处理装置，洗衣机结构包括外桶、设于外桶内的内桶、门体、控制面板、进水系统及洗涤电机，外桶底部和上部分别通过阻尼器和悬挂弹簧与外壳框架连接，进水系统包括进水结构和洗涤剂自动投放装置。所述的外桶为容纳洗涤水的容纳结构，设于外桶内的内桶为洗衣结构。外桶与进水结构相连通。
本发明实施例中，所述的循环水处理装置至少包括絮凝处理单元；絮凝处理单元，包括与外桶连通的絮凝桶和向絮凝桶内投放絮凝剂的絮凝剂投放器，由外桶排水至絮凝桶内絮凝处理。
本发明实施例中，在絮凝桶中设有对其内水进行搅拌的搅拌装置。所述的搅拌装置可以为现有技术中任一结构的，可对絮凝桶中的水进行搅拌的装置。从而，使得絮凝桶中的水可被搅拌，而搅拌水流可提高絮凝剂与水的混合速率、以提高絮凝反应效率；并且进水水流自絮凝桶1顶部的喷头流入絮凝桶1中，以使得喷水质絮凝桶内壁上，实现进水冲洗内壁的目的。优选的，如图5所示，絮凝桶1中的搅拌机构包括被驱动电机11带动旋转的搅拌器；所述的搅拌器包括旋转轴，旋转轴连接有多个绕旋转轴旋转的搅拌叶片12；旋转轴上设有皮带轮13，皮带轮13经皮带14与驱动电机11的输出端相传动连接，使驱动电机20经皮带14传动以带动搅拌叶片12绕旋转轴旋转。
本发明中，循环水处理装置还可以包括一过滤单元；过滤单元，将经絮凝处理单元处理后的絮凝处理水进行过滤处理，以分离絮凝物和洁净水。
本发明中，在絮凝剂中增加比重较大凝结核、减少絮体颗粒中空气含量等手段，可以使得絮凝物的密度大于水的密度，会使得絮凝桶中所生成的絮凝物快速下沉，令絮凝完成后只需对絮凝桶内水静止一段较短时间，就会实现絮凝物全部下沉至絮凝桶底部的目的。为了适用于上述沉降式絮凝的方式，特提出本发明：
如图2所示，本发明实施例中，提高了一种絮凝物沉降式的絮凝洗衣机，所述洗衣机的絮凝桶1上设有出水口9，所述出水口9经三通7分别与洗衣机外部和洗衣机外桶可控的相连通，以将絮凝处理后的下沉的絮凝物外排、或洁净水向洗衣机外桶回流。
本发明中通过在絮凝桶1的出水口9处设置三通6，以在絮凝过程结束后，先将下沉至絮凝桶底部的絮凝物外排至洗衣机外部、再将静止的洁净水回流入洗衣机外桶，令回水中不再含有絮凝物。从而，降低了絮凝物回流入洗衣机外桶的几率，实现了沉降式絮凝洗衣机的絮凝物外排、洁净水回流至外桶中的目的，达到了对洗衣机的进水循环处理、降低耗水量的效果。
实施例一
如图2至图3所示，本实施例中，絮凝桶1包括盖合在絮凝桶1上部开口处的桶盖2；絮凝桶1上设有进水口3、投放口6和出水口9；进水口3设在絮凝桶1的上部，与洗衣机的外桶通过进水管71相连接；投放口6设在絮凝桶1的顶部，用于投放絮凝剂。絮凝桶1的出水口9设于絮凝桶1的底部8；出水口9与三通7的进口相连接，三通7的两个出口分别为回水口4和排水口5，回水口4通过回水管72与外桶相连接。优选的，所述的进水管71、回水管72上分别设有控制水流方向的水泵，以形成洗涤水在外桶与絮凝桶之间的可控循环回路。所述排水口5经设有排水阀的排水管73与洗衣机外部相连通。
本实施例中，所述的三通7由两位三通阀构成，所述两位三通阀有两个控制状态：单独打开排水口侧；单独打开回水口侧。通过对两位三通阀的操控，使得絮凝桶1的出水口9可经三通7、排水口5、排水管73与洗衣机外部相连通，或絮凝桶1的出水口9经三通7、回水口4、回水管72与洗衣机外桶相连通。从而，实现了絮凝桶单独外排絮凝物，或单独回流絮凝处理后洁净水的目的。
当然，本实施例中，还可以将三通7仅仅设置为普通的三通接头，而在回水管72和排水管73上分别设置控制管路中水流通断的单向阀，同样可实现上述控制絮凝桶外流方向的目的。
实施例二
本实施例中介绍了一种沉降式絮凝洗衣机的控制方法，在絮凝过程结束前，将絮凝桶中的水静置一定时间，令絮凝过程中产生的絮凝物下沉至絮凝桶底部；絮凝过程结束后，先将下沉至絮凝桶底部的絮凝物外排至洗衣机外部、再将静止的洁净水回流入洗衣机外桶。
本实施例中，所述絮凝桶1上设有检测絮凝桶1内水位高度的水位传感器，以对絮凝过程中洁净水回流节点进行判断，实现对整个絮凝过程的控制。
上述沉降式絮凝洗衣机的控制方法的具体步骤如下：
步骤11、洗衣机执行洗涤程序结束后；
步骤12、将外桶中的洗涤水流入絮凝桶中，并向絮凝桶内投放絮凝剂，以进行絮凝反应；
步骤13、絮凝反应结束后，将絮凝桶中的水静置一定时间，以令絮凝过程中产生的絮凝物下沉至絮凝桶底部，使絮凝处理后的洁净水与絮凝物上下分层；
步骤14、将出水口处的两位三通阀调整为，回水口侧闭合、排水口侧打开，将下沉的絮凝物外排；
步骤15、检测絮凝桶水位高度下降值是否达到设定值L；若是，执行步骤16；否则，继续执行步骤14；
步骤16、将出水口出的两位三通阀调整为，回水口侧打开、排水口侧闭合，令絮凝桶中的洁净水回流入洗衣机外桶；
步骤17、检测絮凝桶水位高度下降值是否达到最低值；若是，执行步骤18；否则，继续执行步骤16；
步骤18、判断絮凝处理次数是否达到设定值，若是，执行步骤19；若否，再次执行步骤12；
步骤19、洗衣机开始执行漂洗程序。
通过上述设置和方法，使得仅需对絮凝桶内水位检测，并依据水位检测值就可实现对絮凝过程的控制，减少了检测值、简化了判断过程，令洗衣机的结构简化、效率提高。
本实施例中，絮凝桶内的水位下降设定高度L所对应的出水量不低于2至3升。优选的，下降设定高度L为依据絮凝桶型号、絮凝剂类别所对应的设定值，以使得絮凝后生成的絮凝物全部外排。
实施例三
如图2至图3所示，本实施例中，絮凝桶1的底部8设有与洗衣机外部相连通的、将沉降后的絮凝物外排的出水口9，絮凝桶1的底部8自外周向出水口9方向逐渐向下倾斜设置，使得出水口9处于絮凝桶1的最低处，以便于沉降絮凝物的收集、外排。如图2至图4所示，絮凝桶1的底部8呈倾斜角为α的锥形，所述出水口9设于锥形底部8的中心，使得出水口9设于絮凝桶1的最低处，使得沉降的絮凝物被汇集至絮凝桶1的底部8中心锥角处，并在锥形底部8的作用下向出水口9流动，以便于絮凝物的向外排放。
如图4所示，本实施例中，絮凝桶1内设有对水进行搅拌的搅拌结构，所述搅拌结构包括驱动电机11和搅拌叶片12，驱动电机11经皮带结构带动搅拌叶片12旋转，以搅动絮凝桶1中的水流，加快了絮凝反应及絮凝物沉降的速率。优选的，搅拌结构的搅拌叶片12高于回水口4设置，以避免搅拌叶片12搅动下沉的絮凝物，造成对静置分层后的洁净水污染情况的发生。
如图3所示，本实施例中，所述絮凝桶1上部一侧设有电机座10，电机座10上安装有驱动搅拌结构的驱动电机11，所述电机座10的底壁与絮凝桶1的桶壁一体成型，所述电机座10与絮凝桶1桶壁连接处为圆弧形。通过将电机座的底壁进行圆角设计，
以使得絮凝桶内不存在死角，避免絮凝物在电机座处附着情况的发生，以降低絮凝物在絮凝桶内的留存率。
实施例四
如图4所示，本实施例与上述实施例一至三的区别在于：絮凝桶1上设有两个出水口9，两个出水口9分别构成絮凝桶的回水口4和排水口5，回水口4经设有回水阀的管路与洗衣机外桶可控的相连通，排水口5经设有排水阀的管路与洗衣机外部可控的相连通。所述的排水口5设于絮凝桶1的底部8。
通过对回水阀和排水阀的开闭控制，同样可实现絮凝桶中的沉降絮凝物先外排、絮凝处理后的洁净水再回流的目的。
优选的，本实施例中，回水口4高于排水口5设置，以降低下沉絮凝物回流的几率；同时，可在回水结束后，利用絮凝桶内的剩余水对絮凝物进行冲洗。
具体过程如下：在排水阀闭合、回水阀打开的回水过程中，当絮凝桶1内的水位下降至回水口4高度时，将排水阀打开、回水阀闭合，令絮凝桶内的剩余水外排，使絮凝桶排水口处残留的絮凝物排出；并在絮凝桶1内的水位下降至0时，将排水阀、回水阀均闭合，絮凝桶停止排水。
通过在絮凝桶上设置两个不同高度的回水口和排水口，令回水后存在剩余水量，实现利用剩余水量对絮凝桶底部絮凝物冲洗的目的；同时，将洁净水和絮凝物经不同出口外排，降低了絮凝物回流的几率，避免了洁净水被污染的可能。
需要说明的是，上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
