Description

一种洗衣机水过滤系统及其控制方法、洗衣机
本专利申请要求于2014年11月13日提交的，申请号为201410641601.0申请人为青岛海尔滚筒洗衣机有限公司，发明名称为“一种洗衣机水过滤系统及其控制方法、洗衣机”的中国专利申请的优先权，该申请的全文以引用的方式并入本申请中。
技术领域
本发明涉及洗衣机污水处理领域，具体涉及一种洗衣机水过滤系统及其控制方法、洗衣机。
背景技术
随着人们生活水平的提高，洗衣机已逐渐成为人们家中必备的家电之一，大多数人都将洗衣机作为洗衣服的主要工具。
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，需要进更多的水或增加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。
随着环境的恶化，水体的污染，洁净的水资源逐渐成为一种稀缺资源，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，如何在现有洗衣方式的基础上更好的节约水资源，是许多洗衣机生产厂家的研究方向。
专利号为CN00231176.3的实用新型专利，公开了一种节水洗衣机。它设有水过滤装置，水过滤装置设有壳体，水过滤净化装置的进水口与洗衣桶的出水 口相连，水过滤净化装置的后端连有出水装置，出水装置的另一端与洗衣桶相连，出水装置包括水泵及进出管。本实用新型可实现水的循环利用达到节水的目的；同时，废水通过过滤净化被去酸、碱、有机物、去气味脱色后排出，可防止水环境被污染，具有环保效果。然而，该专利由于没有设置气泵，所以不能在洗衣脱水过程结束后将水过滤净化装置内的残留污水排除，时间久了会使得过滤净化装置内的环境恶化。
现有技术中，有的洗衣机上安装有气泵，气泵通过单向阀与过滤组件相连，通过向过滤组件内通入气体进而将过滤组件内的污水排空。然而，现有技术中设计的气泵由于机器空间原因安装于机器底板上，低于整个过滤组件，单向阀处于气泵和过滤组件之间，也低于过滤组件，在机器进行循环及脱水等工作的时候，脏污的水充满前置过滤器或排水管，由于单向阀一侧与前置过滤器底部直接相连，所以前置过滤器或排水管内的污水和杂物会回流至单向阀，使单向阀膜片无法彻底恢复，导致单向阀失效，单向阀失效后水流会经过单向阀流至气泵，使气泵损坏，影响整机气洗效果并导致净水洗效果变差，同时桶清洗次数也会增加。另外，整机结束后过滤组件内的水会经过程序进行排空，但是由于时间原因，组件内残存水不会全部排出，机器停止后残存的水会回流至最低处，也会到单向阀处，所以单向阀处始终接触水流和水压，从而导致失效，使水流流至气泵增加气泵损坏的概率。
基于以上描述，亟需要一种新的洗衣机水过滤系统及其控制方法，以解决现有技术中存在的单向阀和气泵容易接触水而导致损坏，可靠性不高的问题。
发明内容
有鉴于此，本发明的目的在于提供一种洗衣机水过滤系统，此方案可以确保过滤器和气管管路里面的污水和杂物无法接触单向阀和气泵，有效的保护了单向阀和气泵不被损坏，提高了其可靠性。
本发明的再一个目的在于提供一种洗衣机水过滤系统控制方法，通过该方法可对过滤器内剩余的残留水进行排空，使过滤器内部无残留水，保持单向阀 及气泵不接触水，增加其可靠性，从而保护单向阀及气泵不受损坏。

S1、将水过滤系统切换到排水状态。
本发明实施例提出的技术方案的有益技术效果是：
由于本申请提供的洗衣机水过滤系统包括依次连接的气泵、单向阀与过滤器，所述单向阀与所述过滤器之间设有用于防止所述过滤器的水或杂物回流到所述单向阀内的防回水结构。防回水结构可保证单向阀始终与水空气相隔，过滤器和气管管路里面的污水和杂物无法接触单向阀和气泵，有效的保护了单向阀和气泵不被损坏，提高了其可靠性。
由于洗衣机水过滤系统控制方法中，在脱水过程前具有打开气泵并进行预排水的步骤，在脱水过程后具有打开气泵并进行再次排水的步骤，所以通过该方法可对过滤器内剩余的残留水进行排空，使过滤器内部无残留水，保持单向阀及气泵不接触水，增加其可靠性，从而保护单向阀及气泵不受损坏。

具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
装置实施例
本申请提供了一种洗衣机水过滤系统，如图1和图2所示，气泵3与过滤器进气口连接，中间设有单向阀4，避免水流回到气泵3而损坏。由于单向阀4 本身原因以及水流脏污的影响，单向阀4多次使用后会失效，从而使过滤器内的水流回到气泵3，使气泵3损坏；为了避免此种问题，本方案在所述单向阀4与所述过滤器之间设有用于防止所述过滤器的水或杂物回流到所述单向阀4内的防回水结构。
防回水结构可保证单向阀4始终与水或杂物相隔，过滤器和气管管路里面的污水或杂物无法接触单向阀4和气泵3，有效的保护了单向阀4和气泵3不被损坏，提高了其可靠性。
于本实施例中，作为一种优选方案，所述过滤器包括预过滤器2和连接在所述预过滤器2上端的主过滤器8，所述预过滤器2的底部设置有进水口，顶部设有出水口，所述预过滤器2的进水口通过管道与排水泵1相连，所述预过滤器6的出水口与所述主过滤器8的进水口相连通。所述预过滤器2的上端设置有排污口201，下端设置有进气口，所述气泵3的出气口通过气管与所述单向阀4的进气口相连，所述单向阀4的出气口通过气管与所述预过滤器2的进气口相连。本优选方案将单向阀4与预过滤器2进气口之间的管路抬高，所述防回水结构为在所述单向阀4与所述预过滤器2之间的管路上设置的向上弯折的弯头，所述弯头的最高点高于所述预过滤器2的进气口。
于本实施例中，作为更进一步的优选方案，所述弯头的最高处高于预过滤器2的排污口201。即在所述单向阀4与所述预过滤器2之间的管路上设置向上弯折的弯头，所述弯头的最高点高于所述预过滤器2的排污口201最低点所在的水平面。即使气洗管路从所述单向阀4的出气口向上延伸，经过高于所述预过滤器2的排污口201的位置后，向下弯曲延伸至所述预过滤器2的进气口。
此方案由于气洗管路里面始终存在空气，使单向阀4始终与水空气相隔，预过滤器2和气洗管路里面的污水和杂物无法接触单向阀4，有效的保护了单向阀的单向作用，保证了整机的正常运转，使净水洗功能更加有效利用。
于本实施例中，所述预过滤器2的中间设有预过滤网，所述预过滤器2的上端设置有排污口201，所述预过滤器2的进水口与所述预过滤网内部以及所述预过滤器2的排污口201直接连通。所述主过滤器8内设置有主过滤网，所述预过滤网外部与所述主过滤器8的进水口以及主过滤网外部直接连通。
本申请提供的水过滤系统应用在现有的洗衣机上，排水泵1后方增加一预过滤器2和主过滤器8，洗涤漂洗水经过预过滤器2对大颗粒杂物先进行预过滤，后经过主过滤器8进行超滤过滤后，脏水变为干净水重新返回洗涤筒10内，此过程持续约30分钟，基本保证洗涤筒10内的洗涤漂洗水为净水状态，让人感觉到自己的衣物一直处于干净的水中洗涤漂洗。
于本实施例中，为了方便设计及增加可靠性，作为优选方案，所述预过滤器2上设置有用于固定所述弯头的导向结构5，使管路从单向阀4延伸经过导向结构5后向下与预过滤器2进气口连接。
于本实施例中，作为进一步的优选方案，所述导向结构5设置在所述预过滤器2的排污口201处。
具体的，如图3所述，所述导向结构5的一端为与所述排污口201相连的连接法兰501，通过连接法兰501固定连接在所述预过滤器2上。所述连接法兰501的一侧设有保护结构502。所述导向结构5还包括导向柱503，所述导向柱503设置在所述排污口201的一侧，并且落在所述保护结构502的下侧，所述保护结构502位于所述导向柱503的周围，并将所述导向柱503半包围。所述导向柱503优选为螺钉柱。与所述单向阀4出气口连接的气管向上延伸穿过所述导向结构5的导向柱503和保护结构502向下弯曲延伸并与预过滤器2的进气口连接。
于本实施例中，作为优选方案，所述导向结构5还包括与所述连接法兰501和所述保护结构502相配合的密封盖504。如图4所示，所述密封盖504卡合在所述连接法兰501和所述保护结构502的一侧。所述密封盖504可将管路进行约束，避免管路滑脱，此方法为从结构上对气泵3进行保护。
于本实施例中，作为优选方案，如图4所示，所述预过滤器2的排污口201处还设置有排污口转接件6，所述排污口转接件6的一端通过所述连接法兰501与所述排污口201相连，所述排污口转接件6与所述保护结构502相配合的结构如图5至图7所示。并且所述排污口转接件6通过密封装置与所述排污口201密封连接。所述排污口转接件6的另一端与排污管路7相连接，通过排污管路7将所述预过滤器2内的污水排出。所述密封装置优选为O型密封圈。
于本实施例中，通过所述排污口转接件6可以使排污口201向上设计，所述排污管路7可以不用弯曲直接与排污口转接件6相连，此种方法可以节省排污管路7所占用的空间，使排污管路7距离洗衣机的外筒更远，安全系数更高。
于本实施例中，作为一种优选方案，所述排污管路7经过阀体V1后伸向外界。所述主过滤器8的上端也设置有排污口及排水口，所述主过滤器8的排水口相连的有两条管道，一条管道与洗衣机内的洗涤桶10的进水口相连，另一条管道经过阀体V3后伸向外界。所述主过滤器8的排污口与排污管道相连，与所述主过滤器8相连的排污管道经过阀体V2后伸向外界。
于本实施例中，作为另一种优选方案，所述主过滤器8的上端设置有切换阀9，所述切换阀9的三个入口分别与所述主过滤器8的排水口、排污口、所述排污管路7相连；所述切换阀9的出口与主排水通道相连。所述切换阀9替代了阀体V1、阀体V2、阀体V3及其互联管路，节省了安装空间，简化了装配过程，且易于控制，节约了组装成本及控制电路成本。
本申请还提供了一种洗衣机，如图8所示，该洗衣机包括壳体11，所述壳体11内设置有洗涤筒10，该洗衣机的下端还连接有以上所述的洗衣机水过滤系统，所述水过滤系统排水泵1的进水口与所述洗涤筒10的排水口相连，与所述主过滤器8的排水口相连的两条管道中的一条管道与洗衣机内的洗涤桶10的进水口相连，另一条管道经过阀体V3后伸向外界。
方法实施例
为了使洗衣机工作结束后单向阀处不接触污水状态，需要利用程序对水过滤系统的残留水进行排空，之前的做法是在程序最后将切换阀切换到排水状态，然后打开气泵30S对水过滤系统内的残留水进行排空，但是此种方法时间过短，水过滤系统内的残留水不能完全排空。
本方案对脱水过程进行了优化。具体的，该洗衣机水过滤系统控制方法应用于以上所述的洗衣机水过滤系统上。所述洗衣机包括预过滤器2、排水泵1、气泵3，所述排水泵1的进水口与洗涤筒10的排水口连接，出水口与所述预过滤器2的进水口相连，所述气泵3与所述预过滤器2的进气口相连。在洗衣机 完成最后一次漂洗过程后，即进入脱水过程。具体的脱水方法即为水过滤系统控制方法，所述控制方法包括以下步骤：
S1、在脱水开始时将水过滤系统切换到排水状态，然后执行步骤S2。
于本步骤中，如果所述排污管路7经过阀体V1后伸向外界，则将阀体V1打开即可将水过滤系统切换到排水状态。如果所述排污管路7与切换阀9的一个入口相连，则将切换阀9与所述排污管路7接通即可将水过滤系统切换到排水状态。
S2、打开气泵3并持续第一预设时间T1，对预过滤器2内的残留水分进行第一预设时间T1的预排空，关闭气泵3，然后执行步骤S3。
在该步骤中，气泵3打开后，可对预过滤器2进行充气，通过气体将预过滤器2内的残留水分进行排空。
S3、启动排水泵1，执行第二预设时间T2的正常脱水过程。在脱水的这段时间内，水过滤系统内剩余的残留水会流至预过滤器2，所以在脱水结束后还需再执行步骤S4。
S4、打开气泵3并持续第三预设时间T2，对预过滤器2内的残留水分进行第三预设时间T3的再次排空。该步骤同步骤S2的排水过程相同。
于本实施例中，作为优选方案，在步骤S2中，打开气泵3并进行预排水的第一预设时间T1大于等于5秒小于等于30秒。进一步的优选，第一预设时间T1为15秒。当然，所述第一预设时间T1的大小并不局限于此，也可以根据实际需要而设定为其他值。
于本实施例中，作为优选方案，在步骤S3中，正常脱水的持续时间至少为3min，即第二预设时间T2≥3min。第二预设时间T2优选为5min。
于本实施例中，作为优选方案，在步骤S4中，打开气泵3并进行再次排水的第三预设时间T3大于等于5秒小于等于30秒。进一步的优选，第三预设时间T3为15秒。当然，所述第三预设时间T3的大小并不局限于此，也可以根据实际需要而设定为其他值。
以上控制方法从洗衣机工作流程上对气泵进行保护，以此方法使水过滤系统内部无残留水，保持单向阀不接触水，增加其可靠性，从而保护气泵不受损 坏。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
