Description

一种洗衣机排水装置、洗衣机及控制方法 技术领域
本发明属于洗衣机领域，具体地说，涉及一种洗衣机排水装置、洗衣机及控制方法。
背景技术
现有的洗衣机内、外桶之间是一个封闭的环境，只有水流可以通过，由于洗衣机上述结构的局限性和使用环境的特殊性，因此在使用3-5个月之后，内桶外壁和外桶内壁上会粘附污垢，从而滋生不同程度的细菌，而滋生的细菌绝大部分是对人体有害的。
随着人们生活水平的提高和对生活质量要求的提高，洗衣机的卫生问题的解决已经显的很迫切。相关科研机构对洗衣机内部环境的调查情况显示，洗衣机内部污染的严重性已经越来越受到消费者的重视。为了从根本上避免洗衣机对洗涤物的二次污垢，并且更好地对用户的健康负责，洗衣机内部环境的清洁难题已经是一个迫切需要攻克的问题。
中国专利200820183308.4公开了一种带有桶间清洁的套桶洗衣机，它包括内桶、外桶和用于清洁内外桶壁的多个圆形硅胶球，利用洗衣时内桶旋转带动水的流动，从而带动洗衣机内桶、外桶之间的硅胶球运动并不断碰撞内外桶的两壁以达到清洁内外桶壁的目的。但是硅胶球的相对硬度较大，清洁时数量也较多，容易在洗涤过程尤其是脱水过程中产生很大的噪音，试验中发现硬质的东西对内外桶的清洁起到的作用也微乎其微，达不到良好的清洁效果。
申请人之前申请的中国专利201010160548.4中公开了一种使用柔性颗粒清洗洗衣机内外桶之间的洗衣机及方法,该洗衣机采用在洗衣机内外桶之间放置柔性颗粒,通过衣物洗涤过程中水的规律性流动带动柔性颗粒撞击和摩擦洗衣机内外桶壁,实现洗衣机内外桶之间的清洁。但该洗衣机结构在排水后，由于橡胶球或柔性颗粒在桶内处于自由散落状态，高速脱水过程中会产生很大的噪音，同时增加洗衣机的能耗，影响洗衣机的寿命。因此，需要对现有排水装置的结构进行改进，从而提供一个带过滤结构以收集清洗颗粒、且让线屑排出而不被堵塞、在下次洗涤时清洗颗粒能自动投放，并能够自由拆卸以更换清理清洗颗粒的排水装置。
随后，申请人在申请的中国专利201210189764.0中公开了一种洗衣机排水装置，该洗 衣机包括外桶、内桶和波轮，内外桶之间设有清洁桶壁的清洗颗粒，外桶底部设有排水口，所述的排水装置包括在脱水时盛放清洗颗粒、在进水时依靠浮力将清洗颗粒浮出到外桶中清洁桶壁的颗粒收放腔室和排水腔室，颗粒收放腔室通过连通管与排水口相通，颗粒收放腔室具有能使清洗颗粒随水位升高而沿内壁上浮进入连通管由排水口进入外桶的倾斜内壁结构。但经过大量实验，发现进水时清洗颗粒并不能立即依靠浮力由进水口向上浮出到外桶，长时间上层不能浮起导致全部拥挤在倾斜内壁下方，不能完全投放。
接着，申请人在申请号为201510013178.4的中国专利中公开了一种洗衣机排水装置、洗衣机及控制方法，该洗衣机内外桶之间设有清洁桶壁的清洗颗粒，排水装置在排水时收集清洗颗粒至颗粒盛放腔室内，进水时受水的浮力从进水口上浮至洗衣机内外桶之间。排水装置包括排水阀本体、进水口和出水口，进水口与洗衣机外桶排水口连通，排水阀本体内设有与进水口相通的颗粒盛放腔室，颗粒盛放腔室和出水口之间设有颗粒过滤结构，该排水装置还包括通水/通气机构，颗粒盛放腔室设有通口，通口与通水/通气机构之间连通，由通水/通气机构控制通水/通气至颗粒盛放腔室。该结构使得投放清洗颗粒能够全部上浮，投放更快速；且使得排水时线屑能够完全排出，不造成排水堵塞。
基于上述的改进，排水装置已经实现了在排水时收集清洗颗粒，进水时投放快速的目的。但在实验中发现，在洗衣机桶体的转速提升到一定程度，衣物偏重达到一定程度后，在洗衣机脱水运转过程中，清洗颗粒在颗粒盛放腔室中容易因为碰撞反弹作用被弹回到内外桶之间，出现较大的噪音，同时由于高速转动的内桶对清洗颗粒的高速摩擦作用，容易对清洗颗粒表面造成损伤，从而降低清洁球的使用寿命或者降低清洁效果。因此需要一种能够避免收集的清洗颗粒在脱水过程中反弹至内外桶之间的排水装置。
有鉴于此特提出本发明。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
本发明所述的排水装置安装于洗衣机外桶的下方，与洗衣机的排水口连接，洗衣机包括外桶和内桶，内桶和外桶之间设有清洁桶壁的清洗颗粒，清洗颗粒能浮在水中，洗涤过程中通过水流带动清洗颗粒撞击和摩擦内外桶壁实现洗衣机内外桶之间桶壁的清洁，清洁结束后，洗涤水从排水装置排出，清洗颗粒被收集在排水装置内；下次进水时，清洗颗粒再随进水从排水装置中经外桶排水口上浮至内桶和外桶之间，继续清洁内外桶之间的桶壁。
如图1至图5所示，本发明所述的洗衣机排水装置，包括排水阀本体1、进水口2和出水口3，进水口2与洗衣机外桶排水口连通，排水阀本体1内设有与进水口2相通的颗粒收放腔室5，还包括内部具有存水腔室10的存水机构，所述存水机构分别与进水口2和颗粒收放腔室5相通，用于存水并将存水释放至颗粒收放腔室5。
本发明所述排水装置的进水口2设于排水阀本体1的上部，出水口3设置在排水阀本体1的下方，排水阀本体1内设有与进水口2相通的颗粒收放腔室5，颗粒盛放腔室5和出水口3之间设有颗粒过滤结构6。进水口2、颗粒盛放腔室5、出水口3依次相通构成出排水通路。
存水机构内部设有存水腔室，存水机构与进水口相通，在洗衣机排水时，进水口中的水流可进入存水腔室内存水；存水机构又与颗粒收放腔室相通，可以将存水释放到颗粒收放腔室内。存水机构中的存水可以由控制阀控制，根据需要释放到颗粒收放腔室中，或者将存水机构设置为缓释机构，存水可以保持缓慢的速度释放到颗粒收放腔室中。
实施例一
如图1至图5所示，本实施例所述的存水机构为缓释机构4，缓释机构4具有一存水腔室10，所述存水腔室10通过连通口9与颗粒收放腔室5相通，存水腔室10中的存水延缓释放至颗粒收放腔室5。
存水机构为缓释机构，具有缓释的功能，排水时，水进入存水腔室内，在脱水时，存水腔室中的存水以缓慢的速度释放至颗粒收放腔室中。这样当脱水进行到后期，存水腔室内的水释放到颗粒收放腔室中后可对清洗颗粒产生粘滞作用，以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损问题。
进一步的，所述存水腔室10的容积、缓释机构4与颗粒收放腔室5相通的连通口9的设置满足：存水腔室10内的存水完全流入颗粒收放腔室5的时间不小于洗衣机的脱水时间。
所述存水腔室的容积决定存水量，缓释机构与颗粒收放腔室相通的连通口的内径的大小决定存水释放至颗粒收放腔室中的速度。存水腔室的容积和连通口的设置满足上述条件，可以保证在脱水进行到后期时，颗粒收放腔室中仍然具有存水，存水可以对清洗颗粒产生粘滞作用，以释放高速脱水带来的摩擦和碰撞能量，从而避免清洗颗粒碰撞反弹到内外桶之间产生较大的噪音以及产生磨损。
优选地，存水腔室内的存水完全流入颗粒收放腔室的时间等于洗衣机的脱水时间。
实施例二
如图1-5所示，本实施例为实施例一的进一步限定，所述缓释机构4设置在颗粒收放腔室5的上部和/或内部，所述存水腔室10的顶端和/或侧端设有与进水口连通的进口8，所述存水腔室10与颗粒收放腔室5相通的连通口9设置在存水腔室10的侧端和/或底端。
方案1：缓释机构设置在颗粒收放腔室的上部，与排水口并列设置，缓释机构的侧端设有与进水口连通的进口，缓释机构的底端设有与颗粒收放腔室相通的连通口。如此，缓释机构单独设置，其形状、体积可以不受排水阀本体和排水口的限制，也便于在现有的排水装置的基础上进行加装。
另外，缓释机构设置在颗粒收放腔室的上部时，也可以设在排水口内部，缓释机构在顶端设置进口，底端或侧端设置与颗粒收放腔室相通的连通口。如此可以隐藏设置，避免磕碰，但需要进口的内径需要小于清洗颗粒的直径，并需要避免产生对排水效率的影响。
方案2：缓释机构设置在颗粒收放腔室的内部，可以设在进水口下方，也可以设在颗粒收放腔室的侧端。存水腔室的顶端或者侧端设进口，存水腔室的底端或侧端设与颗粒收放腔室相通的连通口。如此可以隐藏设置，避免磕碰，也可以减小对排水的影响，但需要进口的内径需要小于清洗颗粒的直径。
方案3：缓释机构也可以设置多个，将方案1和方案2相结合，同时在颗粒收放腔室的 上部和内部设置缓释机构，以满足对水量的需要。
实施例三
如图1-5所示，本实施例所述的缓释机构4设置在颗粒收放腔室5的顶部，且位于进水口2外部的一侧，所述缓释机构4为上端大下端小的漏斗型，所述缓释机构4的进口8设置在大端的一侧，与进水口2连通，缓释机构4的底端设有与颗粒收放腔室5连通的连通口9。
缓释机构和内部的存水腔室设为上端大下端小的漏斗型，上部侧端的进口内径大于端连通口的内径。排水时，进水口中的水容易进入存水腔室中存水，存水通过连通口缓慢地滴入颗粒收放腔室中，流完存水腔室中的水的时间等于一般的一个脱水程序的时间。当脱水进行到后期，存水内的水可对清洁球产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损问题。
实施例四
如图5所示，本实施例所述的存水腔室10内设有挡流结构11，所述的挡流结构11为上下间隔设置的多个水平挡板，所述水平挡板的一个侧端与存水腔室10的内壁固定连接，并相互交错设置。
或者，水平挡板的四周均与存水腔室的内壁固定连接，并且的水平挡板上设有多个节流孔。
水流进入存水腔室后，由上向下地一层一层通过水平挡板流动，缓慢的经由连通口释放到颗粒收放腔室中。挡流结构可以进一步减缓水流的速度，达到缓释的目的。
实施例五
本实施例所述的缓释机构4设置在颗粒收放腔室5的内部，缓释机构4的顶端一部分位于进水口2下方，另一部分与颗粒收放腔室5的上壁连接，存水腔室10的顶端设有直径小于颗粒直径的进口8，并位于进水口2下方并与进水口2相通；所述缓释机构4的底部悬空，且设有与颗粒收放腔室5相通的连通口9。本实施例将缓释机构隐藏在颗粒收放腔室的内部中，可以避免对缓释机构的磕碰，对排水的影响也较小。
实施例六
本实施例所述的缓释机构4设置在进水口2的内部，缓释机构4的顶端设有内径小于洗衣机的清洗颗粒直径的进口8，所述缓释机构4的侧壁与进水口2的内壁固定连接，缓释机构4的底部悬空，且设有与颗粒收放腔室5相通的连通口9，进口8的内径大于连通口9的 内径。本实施例的缓释机构，隐藏在进水口内，容易进水，且能够缓慢向颗粒收放腔室中放水。
实施例七
本实施例所述的存水机构设置在颗粒收放腔室5的顶部，且位于进水口2外部的一侧，存水机构与颗粒收放腔室5通过连通管连通，连通管上设置控制阀。排水时，存水机构的存水腔室充满水，在脱水时，通过控制阀，达到释放存水的目的。本实施例的存水机构对释放速度限制较小，可在需要用水时打开控制阀，使存水进入颗粒收放腔室。
实施例八
本实施例提供一种具有所述排水装置的洗衣机，所述洗衣机包括内桶和外桶，内桶和外桶之间设有清洗颗粒7，所述排水装置与洗衣机外桶排水口连通，排水时，清洗颗粒7进入颗粒收放腔室5，水进入存水机构内存水，存水机构可将存水释放至颗粒收放腔室5，吸附清洗颗粒。
清洗颗粒能浮在水中，于洗衣机内外桶之间随水流冲击内外桶壁，衣物洗涤过程中通过水流带动清洗颗粒撞击和摩擦内外桶壁实现洗衣机内外桶之间桶壁的清洁，清洁结束后，洗涤水从排水装置排出，清洗颗粒被收集在颗粒盛放腔室，同时洗涤水进入存水机构中，并可将存水释放至颗粒收放腔室，吸附清洗颗粒，避免清洗颗粒碰撞反弹回内外桶之间。
实施例九
本实施例提供一种所述的洗衣机的控制方法，洗衣机执行排水程序时，排水阀打开，洗衣机外桶中的水携带清洗颗粒7进入排水阀的颗粒收放腔室5，同时水进入存水机构内存水；洗衣机执行脱水程序时，存水机构中的存水通至颗粒收放腔室5，吸附清洗颗粒。
进一步的，洗衣机执行排水程序时，排水阀打开，洗衣机外桶中的水携带清洗颗粒进入排水阀的颗粒收放腔室，同时水进入存水机构内存水；洗衣机执行脱水程序到后期时，存水机构与颗粒收放腔室相通的连通管上的控制阀开启，存水机构中的存水释放到颗粒收放腔室中，吸附清洗颗粒，避免清洗颗粒碰撞反弹回内外桶之间。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所 作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
