Description

一种洗衣机及控制方法 技术领域
本发明涉及洗衣机领域，尤其涉及一种洗衣机的清洁絮凝桶的控制方法，还涉及一种装有搅拌机构的洗衣机用絮凝桶。
背景技术
随着人们生活水平的提高，洗衣机现已成为人们日常生活的主要家电之一，洗衣机的洗衣过程主要包括洗涤、漂洗、甩干几个阶段，在洗涤阶段洗衣机进水和洗涤剂对衣物进行洗涤，进入漂洗阶段后为了漂净污渍和残留的洗涤剂，需要进更多的水或执行更多的漂洗次数对衣物进行漂洗，这势必耗费大量的水资源，即使是省水的滚筒洗衣机，为了漂净衣物也需要漂洗至少两次，这一过程至少要消耗30L以上的自来水。有时衣物上的污渍较少或投放的洗涤剂较少，可能两次就漂洗干净了，但由于用户选择了3次漂洗，势必也会造成水资源的浪费，比如6Kg的全自动洗衣机一般两次漂洗基本用水量在100升左右。如何在洗净衣服的同时能够做到省水省电，一直是消费者关注的焦点之一。
目前为止尚未有家用洗衣机配套使用的水净化及循环利用装置，即便是所谓的带有节水功能的洗衣机，一般在洗衣机的侧位安装储水箱，采用水泵进行注水和排水，一般能够一次注水，漂洗3次，起到节水功能。但洗涤后的水不能够保存，同时使洗衣机本身结构复杂、庞大，不利于运输、回收处理等。由于体积、结构以及灵活性等方面的限制，影响了洗衣机原有功能以及节水箱本身功能的充分发挥。
在现有洗衣方式的基础上为了更好的节约水资源，很多厂家投入了大量的研发，以生产具有水净化及循环利用装置，生产带有节水功能的洗衣机。
同时，随着絮凝技术逐渐成熟，在工业领域中逐渐应用和推广开来。采用絮凝原理制作的节水洗衣机也就成为了各洗衣机生产厂家的研发热点。但是，由于现有的絮凝桶对洗涤水或漂洗水进行絮凝处理时，水中的污物与絮凝剂会反应产生絮凝物。由于在絮凝剂中添加有高分子聚合物，絮凝物的粘附性很强，容易附着在絮凝桶的内壁上。絮凝反应后，会有部分絮凝物留存在絮凝桶中，滋生大量细菌，对洗 涤衣物造成二次污染。
针对上述问题，普遍是利用水流冲洗桶壁，并利用絮凝桶中的搅拌机构产生搅拌水流以冲刷桶壁，达到絮凝桶清洁的目的。但是，由于絮凝物极易被水流打散，使得搅拌水流力度不能太大，造成水流的冲刷力度不能清除絮凝物。
同时，若絮凝桶采用进水水流冲刷，则进水水流需覆盖整个桶壁，使得进水结构复杂；且冲刷过程中絮凝桶进水喷头处会存在线屑堵塞的隐患，极易造成进水不畅，进而影响絮凝反应的正常进行。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗衣机，以提高对絮凝桶壁上附着絮凝物的清洁效率；另一目的在于提供一种加装有清洁毛毛球的絮凝桶，以达到清洁毛毛球随搅拌水流清除絮凝桶壁上附着的絮凝物的目的；再一目的在于提供一种在内外桶之间间隙中设置清洁毛毛球的洗衣机，以实现对洗衣机内外桶之间进行清洁的目的；还一目的在于提供一种适用于上述洗衣机的清洁毛毛球，以实现对絮凝桶和/或内外桶间隙进行自清洁的目的。
为实现上述发明目的，本发明采用技术方案的基本构思是：

图4本发明实施例中清洁毛毛球的结构示意图。
主要元件说明：1—絮凝桶，2—第一水泵，3—第二水泵，4—排水阀，5—搅拌叶片，6—驱动电机，7—喷头，8—皮带轮，9—清洁毛毛球，10—外桶，11—内桶，12—波轮，15—清洁毛，17—过滤单元，18—滤网，19—栅格结构。
具体实施方式
下面结合实施例对本发明进行进一步详细的说明。
如图1和图2所示，本发明实施例所述的洗衣机，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10内的内桶11、门体、控制面板、进水系统及洗涤电机，进水系统包括进水结构和洗涤剂投放装置。所述的外桶10为容纳洗涤水的容纳结构，设于外桶10内的内桶11为洗衣结构；优选的，如图2所示，洗衣机结构还可以包括设于内桶11中的波轮12。外桶10与进水结构相连通，以相洗衣机进洗涤水。
本发明实施例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10连通的絮凝桶1和向絮凝桶1内投放絮凝剂的絮凝剂投放器，由外桶10排水至絮凝桶1内絮凝处理。
如图1至图3所示，所述的絮凝桶1设有进水口、回水口和排污口；外桶的出水口经设有第一水泵2的管路与絮凝桶1的进水口相连通，絮凝桶1的回水口经设有第二水泵3的管路与外桶10的进水口相连通，以形成洗涤水在外桶10与絮凝桶1之间的可控循环回路。所述絮凝桶1的排污口经设有排水阀4的管路与洗衣机外部相连通，将洗涤完成后的污水及絮凝物外排。还可以，如图2所示，将排污口设于外桶10的底部，使得外排水自外桶10经排污口、排水阀4后流出洗衣机。
优选的，循环水处理装置还可以包括一过滤单元17；过滤单元17，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。而为了实现对絮凝物和洁净水的分离还可以不采用过滤装置，例如：在絮凝桶中设置水位传感器，使得絮凝桶中的液面始终保持一定高度，以使得漂浮在絮凝桶水面处的絮凝物始终留存在絮凝桶中，也达到了去除絮凝水中絮凝物的目的。
但是，无论采用上述哪种分离方式，都会导致絮凝桶壁上留存有粘附性较强的絮凝物；若絮凝物长期附着在絮凝桶侧壁上，会导致絮凝桶中产生大量细菌。
因此，为了解决上述问题，本发明特提出了，在絮凝桶1中设置至少一个清洁毛毛球9，以使得清洁毛毛球9随絮凝桶中的水流移动，对絮凝桶壁进行摩擦清洁，达到对粘附于絮凝桶内壁上的絮凝物进行彻底清理的目的。
实施例一
如图1至图4所示，本实施例中，所述絮凝桶1中设有多个清洁毛毛球9，以清除附着于絮凝桶中的絮凝物。
如图4所示，本实施例中，清洁毛毛球9具有多条呈条状的清洁毛15；各清洁毛15的一端相固定以构成清洁毛毛球9的中心，另一端发散延伸以构成清洁毛毛球9的外轮廓面。本实施例中，各清洁毛15可一体成型构成清洁毛毛球9；也可将各清洁毛15的一端相互粘连固定，以构成清洁毛毛球9。
本实施例中，所述清洁毛毛球9的外轮廓面可以呈球状、方块状、椭圆球状、圆柱体状、正四面体或其他不规则团状。
本实施例中，清洁毛毛球9上设的各清洁毛15之间相邻一定间隙设置，清洁毛 15由可产生变形且能恢复形变的柔性材质构成。优选的，清洁毛15由橡胶条构成。通过将清洁毛设置为可产生变形且能恢复形变的柔性材质，以增大清洁毛毛球与桶壁的接触面积；同时，降低清洁毛毛球与桶壁摩擦所产生的噪音。
如图4所示，本实施例中，清洁毛毛球9上设的各清洁毛15A、15B、15C的长度均相等，使得清洁毛毛球9的外轮廓呈球状。清洁毛毛球9的粒径D为球状外轮廓的直径。
还可以，本实施例中，清洁毛毛球9上设有至少两种不同长度的清洁毛15，不同长度的清洁毛15交错排布，以便于对空间较窄的夹缝处进行清洁。优选的，清洁毛毛球9上设有三种规格的清洁毛15A、15B、15C，清洁毛15A、15B、15C依次交错排布。进一步优选的，清洁毛15A、15B、15C的长度依次递减，以构成清洁毛毛球9的不规则外轮廓面，达到提高摩擦清洁能力的目的。
本实施例中，絮凝桶1中设有多个不同大小的清洁毛毛球，且各清洁毛毛球9的密度均小于水。优选的，清洁毛毛球9的密度为水密度的0.8至0.9999倍。从而，使得清洁毛毛球9能随水流移动至絮凝桶1中各个位置，实现对絮凝桶内各处清洁的效果。同时，避免清洁毛毛球9太轻，始终处于絮凝桶1液面处；或清洁毛毛球太沉，始终处于絮凝桶1底部情况的发生。
实施例二
本实施例中，介绍了一种洗衣机的清洁絮凝桶的控制方法，其包括如下：向絮凝桶中进水并启动搅拌机构，令清洁毛毛球随搅拌水流移动，对附着于絮凝桶中的絮凝物进行清理。
为实现上述方法，本实施例中，在絮凝桶1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的任一结构，可搅动絮凝桶中的水进行搅拌的装置。例如：如图3所示，一种絮凝桶用搅拌机构，搅拌机构包括絮凝桶1中水平设置的旋转轴，旋转轴上安装有绕旋转轴竖直旋转的皮带轮8，皮带轮8沿径向延伸有多个搅拌杆。搅拌杆上分别设有搅拌叶片5。絮凝桶1的顶部还设有驱动电机6，驱动电机经皮带带动皮带轮8旋转。从而，搅动絮凝桶中的水，搅拌水流将絮凝物打散后与水相互混合。
本实施例中，向絮凝桶中所进的水可以为洗衣机的洗涤水或漂洗水，也可以为自外部进的洁净水。优选的，在洗衣机洗涤和漂洗完成后，将洗涤水和漂洗水均流 入絮凝桶中，并利用清洁毛毛球对絮凝桶壁进行清洁。
通过在洗衣机洗涤、漂洗结束后，将洗涤水和漂洗水流入絮凝桶中进行絮凝处理，并在处理过程中利用清洁毛毛球对絮凝桶壁进行摩擦清洁，达到对絮凝桶壁进行清洁的目的。同时，在洗衣机漂洗完成后，利用排放的漂洗水对絮凝桶进行冲洗，并在冲洗过程中搅动清洁毛毛球，将絮凝桶内壁进行清洁，并将残留絮凝物随漂洗水一块外排，达到有效清除絮凝桶内絮凝物的目的。
实施例三
本实施例中，絮凝桶1上设有至少一个排放口，使絮凝桶1中的水自排放口流出。排放口处设有阻挡结构、和/或排放口的孔径小于清洁毛毛球9的粒径D，以防止清洁毛毛球9随排水流出絮凝桶1。
如图3所示，本实施例中，所述的排放口包括设于絮凝桶1最底部的、与洗衣机外部相连通的排污口，和设于靠近絮凝桶1底部的、向洗衣机外桶10回流洁净水的回水口。
本实施例中，阻挡结构可以为沿排放口径向延伸的多条凸筋，各凸筋交叉排布以构成栅格结构18；凸筋间的间隙小于清洁毛毛球9的粒径D。或者，阻挡结构也可以为覆盖排放口的滤网17，滤网17的过滤孔孔径小于清洁毛毛球9的粒径D。
优选的，排放口处凸筋间的间隙共同构成“+”字型或“米”型缝隙，或滤网的过滤孔为“+”字型或“米”型的通孔，以防止线屑在排放口处被夹持，进而造成排放口堵塞情况的发生。
实施例四
如图1和图2所示，本实施例中，洗衣机还包括外桶10，套装在外桶10中的内桶11，所述的内桶11与外桶10之间的间隙中设有至少一个清洁毛毛球9。
本实施例中，所述的外桶10下部设有向絮凝桶1中进洗涤水的出水口16，所述出水口16处设有阻挡结构、和/或出水口16的孔径小于清洁毛毛球9的粒径，以防止清洁毛毛球9随水流出外桶10。优选的，如图2所示，外桶10的出水口处设置的阻挡结构为覆盖出水口的滤网17。
本实施例中，所述外桶的底部还可以设有向洗衣机外部排水的排水口，排水口经设有排水泵的管路与洗衣机外部相连通，以将洗涤完成后的水外排。所述的排水 口处也设有防止清洁毛毛球9流出的滤网17。
本实施例中，洗衣机执行洗涤或漂洗程序时，内桶开始旋转，以搅动外桶中的洗涤水，令清洁毛毛球随洗涤水流在内外桶之间移动，对附着在内外桶之间的污物进行清理。从而，使得随洗涤水流移动的清洁毛毛球可以将附着于内桶外壁和外桶内壁上的污物进行摩擦清除，达到对洗衣机的内外桶自清洁的目的。
如图2所示，本实施例中，设于内桶11与外桶10之间的间隙中设有多种不同尺寸规格的清洁毛毛球9；优选的，至少具有两种规格尺寸的清洁毛毛球9，其中一种清洁毛毛球9的粒径D大于内外桶间隙宽度、另一种清洁毛毛球9的粒径D小于内外桶间隙宽度。从而，使得内外桶之间间隙的任一位置均可被清洁毛毛球摩擦清洁，以实现对内外桶间隙无死角清洁的目的。
实施例五
如图1和图3所示，本实施例中，所述的絮凝桶1设有进水口、回水口和排污口。外桶的出水口经设有第一水泵2的管路与絮凝桶1的进水口相连通，絮凝桶1的回水口经设有第二水泵3的管路与外桶的进水口相连通，以形成洗涤水在外桶与絮凝桶1之间的可控循环回路。所述絮凝桶1的排污口13经设有排水阀4的管路与洗衣机外部相连通。
本实施例中，絮凝桶的进水口由喷头7构成。所述的喷头7设于絮凝桶1的顶端，所述的喷头7上设有多个喷水孔，各喷水孔绕喷头7的轴线环绕设置。从而，使得进水水流可经喷头作用，均匀喷射至絮凝桶的侧壁各部分，冲洗絮凝桶侧壁上附着的絮凝物；同时，自喷头喷入的喷淋水还可以对清洁毛毛球9进行冲洗，避免清洁毛毛球表面残留有絮凝物。
上述实施例中的实施方案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。
