Description

一种洗衣机的排水密封装置及洗衣机 技术领域
本发明涉及无孔内桶洗衣机的排水技术领域，具体地，涉及一种洗衣机的排水密封装置及洗衣机。
背景技术
现有洗衣机，结构一般都包括内桶和外桶两个部分，内桶和外桶之间是相通的，内桶上开设脱水孔用于脱水，外桶封闭为盛水桶。这样，洗衣机在工作时，内桶和外桶之间区域是充满水的，在洗衣机长时间的使用运转过程中，内桶和外桶之间的区域会被水中带有的污垢和线屑覆盖满，长年累月的使用会产生细菌和异味，对于洗涤效果和用户体验均造成较大的影响。
为了解决内桶与外桶之间充满水造成内桶和外桶的污染问题，现有一种新型洗衣机，能够将内桶与外桶之间进行密封，以杜绝污染问题。已知的解决方案有，将内桶设计为无孔内桶，这样就将内桶与外桶之间进行隔绝，内桶充当盛水桶，同时为了实现内桶的排水，通过一个外在密封机构，顶在内桶的排水孔上，实现内桶的密封。这种情况下，内桶与外桶相对是不能够转动的；当内桶中的负载因洗涤物转动产生晃动时，密封机构也存在晃动的隐患，可能会导致漏水的产生。
另外，随着生活水平的提高，用户对于衣物的洗涤效果要求也越来越高，现有洗衣机基本都是在洗涤或者漂洗过程中通过波轮转动搅拌水流洗涤衣物，这样的洗涤方式形成的水流较为单一，洗涤效果有待提高。现有一种双动力洗衣机，在洗涤和漂洗时可以控制波轮和内桶进行反向转动，以给水流更多动力，增多水流方式，增强水流效果，具有较好的洗涤效果。
综上所述，本发明旨在提供一种可实现桶间无水的洗衣机，且同时具有双动力洗衣机的洗涤方式，满足用户对于衣物洁净度和洗衣机洁净度的双重要求。

进一步优选地，所述平滑结构的上表面呈向下弯曲的圆弧面。
具体地，所述的套装部601为内部中空的套筒，所述封堵部件100的底面具有与排水孔相配合的圆环密封部，所述的连接部102为设置在圆环密封部的圆心位置处的中心杆，所述中心杆插入套筒内且可相对滑动；
优选地，所述的封堵部件100还包括密封垫300，所述的密封垫300设置在圆环密封部上。
为了保持封堵部件100的自密封以及在打开排水孔后的复位密封，所述的密封机构包括弹性部件，所述弹性部件一端止抵于支撑部件600，另外一端止抵于封堵部件100，所述的弹性部件在封堵部件100滑动至与排水孔分离状态时形变，实现封堵部件100的弹性复位密封；
优选地，所述弹性部件的初始状态处于压缩状态，以保持封堵部件与排水孔之间的密封配合。
作为本实施例的一种实施方式，所述的弹性部件为压弹簧200，压弹簧200套设在套装部601的中空滑道内，压弹簧200一端止抵于套装部601，另一端止抵于封堵部件100。
进一步地，所述封堵部件100的中心杆的端部安装固定扣700，所述套装部601的上端具有朝向中空滑道内部延伸一定距离形成限位台阶，所述的压弹簧200套装在中心杆上，一端止抵于固定700，另一端止抵于限位台阶。
本实施例所述封堵部件的包括顶盖，顶盖的上端面呈圆弧面，顶盖的下端面具有与排 水孔密封配合的密封部。
由于在排水时，经由排水孔流出的洗涤水可能会进入到支撑部件的套装部601内，随着时间的增长，若洗涤水的线屑、污物或者杂物进入后可能会对套装部601内部的构件，比如压弹簧200造成影响，导致其不能正常工作，从而影响封堵部件的正常复位及密封效果，因此，为了保证紧套装部601内部构件工作环境的相对稳定性，本实施例所述的密封机构包括密封部件，密封部件的两端密封安装在封堵部件和支撑部件之间，形成密封空间。
优选地，所述的密封部件为密封螺纹套1000，密封螺纹套1000的一端与封堵部件之间密封连接，另一端与支撑部件的套装部密封连接，形成完全罩住所述套装部601内部的密封空间。密封螺纹套1000具有密封效果，且能随着顶盖的上下运动进行伸缩，结构简单，成本较低，保证了压弹簧200工作环境的密封性。
本实施例的密封机构各零部件之间的装配关系见图1，首先将支撑部件600用两颗螺钉装配到法兰盘400上，再将带有密封垫300的封堵部件100装配到套装部601的中空滑道内，从另一端将压弹簧200使用固定扣700卡住，安装完成。
密封的工作原理：压弹簧200受到压缩，一端力作用在支撑部件600上，一端作用在固定扣700上，固定扣700通过封堵部件100的中心杆传递到整个封堵部件100上，封堵部件100在弹簧力的作用下压紧内桶底，起到密封的效果。如图1所示。
排水的工作原理：当准备排水时，内桶通过一个定位结构，实现密封机构和驱动机构的位置重合，此时驱动机构1000的输出端顶到固定扣700上，带动顶盖上移，顶盖和排水孔之间产生间隙，实现排水。此时压弹簧200也被压缩到极限位置。排水完成后，驱动机构1000的输出端1001缩回，顶盖在弹簧力的作用下重新将排水孔密封住。如图2所示。
本实施例的排水密封装置设计时其中内桶和密封垫，都采用了锥形的设计，这样当衣物聚集到排水口附近时，在水流的冲击下，和异物本身重力的作用下，更便于异物的排出。也有利于防止长时间运转线屑的堆积。
将密封的橡胶垫固定与整个密封机构的顶部，考虑到异物紧贴这内桶底排走时，因内桶的为金属不锈钢才走，其摩擦阻尼小于橡胶的摩擦阻力，更有利于异物的排出。也有利于防止长时间运转线屑的堆积。
支撑部件600采用马鞍形状结构，防止当异物排出内桶时，如果接触当支架，假设支架为平面，卡主异物的可能性更大一些。半圆形结构设计阻尼减少，也有利于防止长时间运转线屑的堆积。
支撑部件600的套装部601可以和封堵部件100的中心杆做过度配合，有效的防止线 屑、异物进入弹簧腔内，导致弹簧工作时被卡主。
优选地，所述的驱动机构可以选择排水阀，排水阀的顶住，要大于固定扣700的内圆柱的直径，确保排水阀的顶住推力是作用在固定扣上的，防止推力直接作用在封堵部件100的中心杆上，存在定出脱落的隐患。此处也可以使用螺纹配合固定，弹性卡扣固定。
作为本实施例的一种实施方式，洗衣机包括设置在内桶外部的集水装置800，排水密封装置还包括驱动机构900，所述的驱动机构900安装在集水装置上对应于密封机构，所述驱动机构具有可上下伸缩的输出端：
洗涤或者漂洗时，所述驱动机构的输出端缩回，密封机构与排水孔密封配合，内桶内盛放洗涤水；排水时，所述驱动机构的输出端伸出将密封机构顶开与排水孔分离，排水孔开启，内桶内的洗涤水由排水孔流出到集水装置内排出。
本实施例的驱动机构的输出端1001为一伸缩杆，所述伸缩杆可伸入紧固套600中将封堵部件100顶起。
本实施例同时提供一种洗衣机，包括内桶，所述内桶的底部开设排水孔，所述内桶的底部安装排水密封装置，包括可与排水孔密封配合的密封机构，密封机构包括封堵部件和支撑部件，支撑部件固定安装在内桶的底部且延伸至排水孔处，封堵部件可相对滑动的安装在支撑部件上：
洗涤或者漂洗时，所述封堵部件与排水孔密封配合，内桶内盛放洗涤水；排水时，所述封堵部件将排水孔打开，内桶内的洗涤水由排水孔排出。
本实施例的洗衣机可以实现桶间无水，解决了内桶与外桶之间区域容易被污染的问题，且本实施例的洗衣机可以实现双动力洗衣，提升洗衣效果，满足用户洗衣要求。
本实施例的内桶为无孔内桶，本实施例内桶的桶壁上除在上部设置一圈脱水孔之前，其他都是封闭的，优选地，脱水孔设置在内桶口处，内桶口上安装平衡环后，平衡环可将脱水孔隐藏，实现观感上的无孔内桶结构。
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。
