Description

一种洗衣机排水装置、洗衣机及控制方法 技术领域
本发明涉及洗衣机领域，特别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。
此外，在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。
但上述洗衣机结构，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。
还有，在申请人之前申请的中国专利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，如图1所示，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盛放腔室1’和排水腔室2’，颗粒盛放腔室1’通过连通管3’与排 水口相通，颗粒盛放腔室1’具有能使清洗颗粒4’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。
但是，经过大量实验，上述结构仍存在如下问题：1、清洗颗粒整体粘附在倾斜内壁上，在洗衣机进水时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；尤其是若颗粒存放在颗粒盛放腔室时间长，则底层清洗颗粒受挤压左右完全粘附在颗粒盛放腔室底壁，不利于其完全投放；2、洗衣机排水，由于清洗颗粒的影响，线屑容易聚集在过滤结构前部不能排出，较长时间积累不仅会影响排水效率，还会将清洗颗粒缠住，不利于再次投放。
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，提供一种结构简单的洗衣机排水装置，使得线屑完全排出，不造成排水堵塞及二次污染。
本发明的另一目的在于提供一种具有上述排水装置的洗衣机。
本发明的再一目的在于提供一种洗衣机控制方法。
为解决上述技术问题，本发明采用技术方案的基本构思是：
一种洗衣机排水装置，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，所述的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。
进一步的，所述的通水/通气机构为洗衣机进水阀，进水阀通过一导水管与通口连通，由进水阀控制进水至颗粒盛放腔室。
或者，所述的通水/通气机构为气泵，气泵通过一导气管与通口连通，由气泵控制吹气至颗粒盛放腔室。
进一步的，所述的通口与通水/通气机构之间设有单向阀。
进一步的，所述通口的通水/通气方向对应颗粒过滤结构的前部设置。
进一步的，所述的通口至少设有一个，设于颗粒盛放腔室的上部或侧部或底部，通过一多通管与通水/通气机构连通。
进一步的，所述的通口沿出水/出气方向内径渐小。该结构增加进水水压/进气气压，利用较大的进水/进气冲击力搅动颗粒盛放腔室的清洗颗粒。
本发明另外提供一种洗衣机排水装置，包括排水阀本体、进水口和出水口，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，该排水装置还包括向颗粒盛放腔室进水的水泵机构。
本发明通过水泵机构进水至颗粒盛放腔室冲击颗粒盛放腔室的清洗颗粒，使其无规则的运动，以松散被阻挡或缠绕的线屑团，且重新形成新的排水间隙，继续排水使得线屑顺利排出。
进一步的，所述的水泵机构包括一反向水泵，反向水泵的出水口与排水装置的出水口连通，反向水泵的进水口与洗衣机排水管连通。排水过程中，利用排水管内的蓄水逆向导水至颗粒盛放腔室内以冲击缠绕在清洗颗粒上的线屑以及阻挡在颗粒过滤结构前部影响线屑通过的清洗颗粒。
进一步的，所述的反向水泵后部安装有一向外排水的排水泵，排水泵的进水口与反向水泵的进水口连通，排水泵的出水口与洗衣机排水管连通。
或者上述方案的替换方案为，所述的水泵机构包括一循环水泵，该循环水泵进水口与洗衣机外桶底连通，出水口与颗粒盛放腔室连通。
再或者替换方案为，所述的水泵机构包括一双向排水泵，所述双向排水泵包括一个进水口和两个出水口，进水口与排水装置的出水口连通，一出水口与洗衣机排水管连通，另一出水口与颗粒盛放腔室连通。通过控制双向排水泵的出水方向来导通颗粒盛放腔室的循环水路或洗衣机的排水水路。
进一步的替换方案为，所述的水泵机构包括一排水泵，排水泵进水口与排水装置的出水口连通，出水口与一多通换向阀连通，多通换向阀的一出水口与颗粒盛放腔室连通。
进一步的，所述的颗粒盛放腔室与水泵机构连通的水路上设有单向阀或截止阀。
进一步的，所述的颗粒盛放腔室设有与水泵机构连通的通口，该通口尺寸小于颗粒尺寸或者设有过滤装置。
优选的，通口设于颗粒盛放腔室对应颗粒过滤结构阻挡颗粒一侧的底部以进水直接冲击该侧的清洗颗粒和线屑。
本发明所述的洗衣机包括外桶和内桶，内外桶之间设有清洁桶壁的清洗颗粒，外桶排水 口与下方的排水装置连通，该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。
本发明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内；所述的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。
在内外桶之间放置清洗颗粒以清洁内外桶壁是借鉴了内桶中洗涤物摩擦内桶使其不会粘附污垢滋生细菌的原理；清洗颗粒可以是海绵类的物质，也可以是橡胶或者塑料发泡物，如发泡橡胶，发泡塑料、发泡复合聚氨酯，其有一定的弹性，干燥状态下其密度比水小，具有一定弹性和耐磨性，在水中具有浸透水的性质，价格便宜，使用多次之后可以直接通过打开颗粒盛放腔室开口的密封盖取出回收，然后重新使用新的清洗颗粒。
本发明所述洗衣机的控制方法，能够直接向颗粒盛放腔室进水或吹气，使得进水时清洗颗粒能够活动上浮，投放快速、稳定；在洗衣机投放清洗颗粒时，由通水/通气机构间隔或持续控制通水/通气至颗粒盛放腔室，冲击清洗颗粒活动，随进水水位上升投放到洗衣机内外桶之间。
进一步的，所述的通水/通气机构控制通水/通气至颗粒盛放腔室设定的时间后，或者外桶进水设定水位后，通水/通气机构停止工作。
本发明所述洗衣机的控制方法，排水过程中，控制通水/通气机构或者水泵机构通水或通气至颗粒盛放腔室中，冲散与颗粒缠绕的线屑和/或被颗粒过滤结构阻挡的线屑团以顺利排水。
排水过程中，检测单位时间外桶水位降低小于设定值或者水位下降至设定水位，此时，线屑纠缠阻挡在颗粒过滤结构的前部，由通水/通气机构或者水泵机构控制通水或通气至颗粒盛放腔室。
或者，排水过程中，以设定的间隔时间通水/通气至颗粒盛放腔室，防止线屑纠缠成团不能排出，也防止缠绕清洗颗粒从而影响排水和下次投放。
当检测外桶中排水至设定水位时，控制通水/通气机构或者水泵机构停止向颗粒盛放腔室通水或通气。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明所述的排水装置针对于具有在内外桶之间带有清洗颗粒清洗内外桶壁功能的洗衣 机，能够利用排水收集清洗颗粒以避免脱水时清洗颗粒在内外桶之间撞击桶壁产生噪音，且在下次洗涤时能利用进水浮力完全将清洗颗粒重新投放到内外桶之间继续清洁桶壁，采用的改进结构更容易使得清洗颗粒的再次投放使用，避免了清洗颗粒粘附在内壁上造成的堵塞，结构简单、生产安装成本低。
本发明利用通水/通气机构控制通水/通气至颗粒盛放腔室搅动清洗颗粒，使得清洗颗粒之间松散且不粘附在颗粒盛放腔室内壁上，利于清洗颗粒的投放；洗衣机排水时，由于清洗颗粒的影响，线屑容易聚集在颗粒过滤结构前部不能排出，本发明利用通水或通气冲击线屑团，使得线屑能够完全排出，避免了排水堵塞和线屑残留导致的细菌滋生。本发明结构简单、设计合理，既能够在进水时加速清洗颗粒的完全投放，又能够保证排水的通畅。
