Description

一种自循环絮凝洗衣机及控制方法 技术领域
本发明涉及洗涤设备领域的自清洁洗衣机，尤其涉及一种可对自循环洗涤水进行絮凝自清洁处理的洗衣机，还涉及一种上述洗衣机的控制方法。
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水基本用水量在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。
因此，申请人之前提出了申请号为201310356428.5的中国专利申请，一种具有循环水处理功能的洗衣机及其控制方法，洗衣机包括外桶、设于外桶内的洗衣结构及设于外桶下方的絮凝水处理装置，所述的絮凝水处理装置包括絮凝处理单元和过滤单元，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；过滤单元包括过滤容器和设于过滤容器内的过滤网，过滤容器分别与絮凝桶和外桶连通，将絮凝桶内絮凝处理的水过滤后重新排入外桶内再次使用。本申请循环絮凝过滤处理水至洗涤结束，将水排入絮凝水处理装置进行絮凝处理单元和过滤单元清洗，最后排出。本申请具有节约水资源、减少水污染、保护环境的特点。
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；产生的絮状物会沉淀或者漂浮，使得水和污染物分离开，达到对洗涤水和/或漂洗水进行净化的目的。
同时，在洗涤过程中对洗涤水进行上下循环流动的洗衣机，由于循环水流使得洗涤液与衣物的接触更为充分，提高了洗涤效率。因此，如何将洗涤水絮凝自清洁和自循环流动两种洗涤方式进行共同设于同一洗衣机上，就成为了研发热点。
有鉴于此，特提出本发明。
发明内容
本发明的目的为克服现有技术的不足，提供一种自循环絮凝洗衣机，以实现对洗涤水进行自循环流动洗涤和絮凝自清洁的目的；本发明的另一目的在于提供一种止回结构，以实现循环水流与絮凝桶之间自动隔离、防回流的目的。
为了实现该目的，本发明采用如下技术方案：
一种自循环絮凝洗衣机，其包括外桶、设于外桶内的洗衣结构及设于外桶外部的絮凝水处理装置，所述的絮凝水处理装置包括对外桶排出的水进行絮凝处理的絮凝桶；其特征在于：洗衣机还设有带动外桶中的洗涤水由下向上自循环的循环管；循环管的一端经三通与絮凝桶的回水口和外桶上部的自循环进水口分别相连通，三通与絮凝桶的回水口之间设有防止絮凝水回流的止回结构。
进一步，絮凝水处理装置还包括对絮凝处理后的水进行过滤以分离絮凝物的过滤装置；过滤装置的出水口与三通相连，所述的止回结构设于过滤装置的出水口处。
进一步，所述的止回结构为止回垫圈，止回垫圈包括呈圆环状的、套装于过滤装置出水口管壁上的安装部和呈圆盘状的、盖在过滤装置出水口的止逆部，安装部和止逆部经连接柱相连接，所述连接柱为可产生弹性变形的柔性材质，使止逆部在过滤装置中水流压力的作用下产生向三通方向的移动，达到水流在过滤装置与三通之间单向流动的目的。
进一步，所述的止回结构为控制出水口通断的控制阀，或控制出水口水流方向为自过滤装置向三通方向流动的单向阀。
进一步，所述循环管的一端与外桶底部的自循环出水口相连、另一端经三通与外桶上部的自循环进水口和过滤装置的出水口分别相连通，所述循环管上设有为自循环水流提供动力的循环泵，使循环管中的水流自外桶的自循环出口向三通方向流动。
进一步，外桶的底部设有出水口，所述出水口经设有第一水泵的管路与絮凝桶的进水口相连通，使外桶中的水经第一水泵流入絮凝桶中；絮凝桶的底部设有回水口和排水 口，回水口经设有第二水泵的管路与过滤装置的进水口相连通，使絮凝筒中絮凝处理后的水经第二水泵流入过滤装置中；排水口经设有排水阀的管路延伸至洗衣机外部的排水口处，使洗涤完成后或絮凝后不达标的洗涤水外排。
本发明的再一目的在于提供一种采用如上任一所述洗衣机的控制方法，其特征在于：洗衣机洗涤过程中，在止回结构的作用下，洗涤水在外桶与循环管之间进行循环流动；洗涤完成后，洗涤水进行絮凝处理，絮凝处理完成、并达标后的絮凝水回流入外桶和/或循环管中，以供洗衣机漂洗使用。
进一步，在洗涤过程中，将外桶的自循环出水口和自循环进水口经循环管相连通，并经止回结构作用将絮凝桶与循环管相断开；在絮凝处理结束过程中，将外桶的自循环出水口和自循环进水口经循环管相连通，并经止回结构作用将絮凝桶与循环管相连通，令絮凝处理达标后的絮凝水回流入外桶中。
进一步，絮凝处理后的絮凝水经过滤处理，对絮凝水中残留的絮凝物进行过滤，并将过滤后的洁净水回流入外桶和/或循环管中。

具体实施方式
下面结合附图，对本发明做进一步介绍。
如图1至图4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，还设有絮凝水处理装置，洗衣机结构包括外桶2、设于外桶2内的洗衣结构、进水系统。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，进水系统包括设有进水阀1的进水结构和洗涤剂自动投放装置11。所述的外桶2为容纳洗涤水的容纳结构，设于外桶内的洗衣结构可以为内桶和/或波轮。外桶2的外部设有循环管16，循环管16中设有循环泵4，使得洗涤水在外桶2与循环管16之间进行自循环流动，以提高洗衣机的洗涤效率。
本发明实施例所述的絮凝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2连通的絮凝桶7和向絮凝桶7内投放絮凝剂的絮凝剂投放器8，由外桶2排水至絮凝桶7内絮凝处理，并将絮凝处理后达标的洁净水回流入外桶中供洗涤衣物使用，以实现对洗涤水和/或漂洗水循环自清洁利用的目的。
如图1至图5所示，本发明实施例中，洗衣机还设有带动外桶1中的洗涤水由下向上自循环的循环管16；循环管16的一端与外桶1下部的自循环出水口相连通，另一端经三通10与絮凝桶7的出水口和外桶1的自循环进水口分别相连通，三通10与絮凝桶 7的出水口之间设有防止絮凝水向絮凝桶7回流的止回结构12。所述循环管16上设有为自循环水流提供动力的循环泵4，使循环管16中的水流自外桶2的自循环出水口向三通10方向流动。
本发明实施例中，洗衣机洗涤过程中，洗涤水在外桶2与循环管16之间进行循环流动；洗涤完成后，洗涤水流入絮凝桶7中进行絮凝处理，絮凝处理完成、并达标后的絮凝水经止回结构12、循环管16回流入外桶2中，以供洗衣机漂洗使用。
通过上述设置和方法，使得洗衣机同时具有了絮凝自清洁处理与循环水洗涤功能；同时，将絮凝水回流装置集成到循环管上，使得洗衣机的结构更为紧凑、提高了洗衣机的集成化程度。尤其是，通过设置止回结构，使得自循环水流不会向絮凝桶中倒流，使得絮凝水处理与循环水洗涤功能相互不干涉。
实施例一
如图1至图3所示，本实施例中，絮凝水处理装置还可以包括一过滤装置9，过滤装置9对絮凝处理后的絮凝水进行过滤处理，使絮凝水中残留的絮凝物被过滤分离。过滤装置9的出水口与三通10相连，使得过滤后的洁净水经三通10回流入外桶2和循环管16中。
本实施例中，所述的止回结构12设于过滤装置9的出水口处，以流经三通10的自循环水流无法回流入过滤装置9中、且过滤装置9中絮凝、过滤后的洁净水可经三通流入外桶2和循环管16中，实现了絮凝自清洁处理与循环水洗涤相互不干涉的目的。
如图1至图4所示，本实施例中，外桶2的上部设有自循环进水口24和进水口23，底部设有出水口21和自循环出水口22；优选的，所述的自循环进水口24和进水口23为同一结构，以简化洗衣机的结构。絮凝桶7的底部设有排污口73，下部设有回水口72，上部设有进水口71。
本实施例中，外桶2的出水口22经设有第一水泵3的管路与絮凝桶7的进水口71相连通，絮凝桶7的回水口72经设有第二水泵5的管路与过滤装置9的进水口91相连通，过滤装置9的出水口92经三通10与外桶2的自循环进水口24相连通，以形成洗涤水在外桶2与絮凝桶7之间的可控循环回路。所述絮凝桶7的排污口73经设有排水阀6的管路延伸至洗衣机外部，将洗涤完成后的、或絮凝处理后未达标的污水及絮凝物外排。
实施例二
如图1、图6和图7所示，本实施例中，所述的止回结构12为止回垫圈15，止回垫圈15包括呈圆环状的、套装于过滤装置9出水口管壁上的安装部152和呈圆盘状的、盖在过滤装置9出水口的止逆部151，安装部152和止逆部151经连接柱153构成一体件。通过在过滤装置出水口处设置止回垫圈15，使得絮凝处理后的过滤装置9中洁净水的压力可推开止逆部151，经三通流入外桶和循环管中；同时，在洗衣机洗涤过程中，止逆部151覆盖出水口，使得循环管16中的水只能流入外桶2中、而无法向过滤装置9中回流，保证了絮凝反应和自循环洗涤的相互不干涉。
本实施例中，所述连接柱153为可产生弹性变形的柔性材质，连接柱153的两端分别与止逆部151和安装部152的外周相连接，且安装部152相对止逆部151远离三通10设置，使止逆部151在过滤装置9中水流压力的作用下产生向三通10方向的移动，达到水流在过滤装置9与三通10之间单向流动的目的。
通过设置上述结构的止回垫圈，使止逆部在水流压力作用下打开或闭合出水口，实现了出水口处的水流只能向三通方向单向流动的目的。
本实施例中，还可以如图2所示，将所述的止回结构12为控制过滤装置9出水口水流方向的单向阀13。在单向阀13的作用下，使得水流只能沿自过滤装置9出水口向三通10方向单一流动。通过在三通10与过滤装置9出水口之间设置单向阀，达到了与上述止回垫圈15相同的技术效果，使得絮凝水处理与循环水洗涤功能相互不干涉。
实施例三
如图3所示，本实施例中，所述的止回结构12为控制过滤装置9出水口与三通10之间水流通断的控制阀14，控制阀14可控地打开或闭合出水口，以实现对回流絮凝水的控制。
本实施例中，洗衣机的具体工作方式如下：
1)、在洗涤过程中，将控制阀闭合，使得外桶的自循环出水口和自循环进水口经循环管相连通，并使絮凝桶与循环管相断开；
2)、在絮凝处理结束过程中，将控制阀打开，使得外桶的自循环出水口和自循环进水口经循环管相连通，并使絮凝桶与循环管相连通，令絮凝处理达标后的絮凝水回流入外桶中；
3)、在洗衣机漂洗完成或絮凝处理完成后的絮凝水未达标后，外桶中洗涤水和絮凝桶中的絮凝水全部外排至洗衣机外部。
通过上述设置和方法，同样可实现对三通中水流流向的控制，达到在洗衣机上集成絮凝反应和自循环洗涤的目的。
实施例四
如图4所示，本实施例中，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，如：在絮凝桶7中设置水位传感器17，使得絮凝桶7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。
如图4所示，本实施例中，将絮凝桶7的回水口直接与三通10相连，以使得絮凝处理完成后的洁净水直接经三通10回流入外桶2中，供洗衣机漂洗使用。本实施例中，所述的止回结构12设于絮凝桶7的回水口与三通10之间的管路上，以避免循环管处的水向絮凝桶回流情况的发生。优选的，所述的止回结构12设于三通10与第二水泵5之间的管路上；进一步优选的，所述的止回结构12设于三通10与第二水泵5相连的一开口处，以避免循环水流入三通10与第二水泵5之间管路情况的发生。
通过上述设置，使得不设置过滤装置的絮凝自清洁洗衣机同样可集成循环水洗涤的功能，以提高本发明所述方法和装置的适用性，达到提高产品多样性的目的。
以上所述仅为本发明的优选实施方式，应当指出，对于本领域的普通技术人员而言，在不脱离本发明原理前提下，还可以做出多种变形和改进，这也应该视为本发明的保护范围。
