洗衣机作为人们日常生活中使用最为广泛的一种家用电器，帮助人们摆脱了洗衣的烦恼，给人们带来了极大的便利。但是洗衣机也具有一定的缺点，比如说耗时较长、耗水量较大等，随着社会的发展，水资源作为一种重要的自然资源变得越来越重要，人们的节水意识也随之提高，而如何实现洗衣机的节水功能便显得尤为重要。
为了解决洗衣机的节水问题，现在也提出了一些专利，比如专利号为201410215346.3，名称为一种滚筒洗衣机的中国发明专利，该发明涉及一种滚筒洗衣机，包括箱体，箱体内设有内筒和外筒，外筒与箱体之间设有门封，内筒与驱动装置相连，所述的内筒为无孔内筒，且所述的内筒为筒底处直径小、筒口处直径大的锥形筒，内筒的筒口处向内呈弧形收拢，所述的门封上设有进水导管，进水导管的一端与洗涤水快速加热装置相连，进水导管的另一端穿过门封伸入内筒内，所述的外筒上设有排水口及水压检测装置。由上述技术方案可知，该发明的内筒为无孔内筒，通过设置在门封上的进水导管实现内筒进水，并通过内筒自身的形状在脱水过程中实现排水，这样可以避免在内、外筒之间存水，大幅节约了洗涤用水量。
上述发明提供了一种具有无孔内筒的滚筒洗衣机，但仅仅是将现有滚筒洗衣机的内筒设计为无孔结构，现实意义很小。因为衣物洗涤须有一定的洗涤水浸泡，如果要实现浸泡的效果，无孔内筒中的需要存有一定的水量，这样会增大电机的负担，耗电等问题也随之而来。另外，该专利公开的滚筒洗衣机进水的方式是通过门封，由于门封主要的作用是实现洗衣机外筒的筒口的密封，在门封上设置进水导管容易影响门封的密封效果，不易实现，且该专利不能实现对内筒内进水水位的检测。
另外，针对具有无孔内筒的滚筒洗衣机，保持内筒上的排水口的密封是实现内筒与外筒之间无水的关键，现有技术存在有在排水口上设置密封件，通过活动件与密封件密封接触封堵排水口的方案，但是由于内筒的筒壁一般多为圆弧形，将密封件安装在圆弧形内筒壁上较为复杂，且不易保持稳固，容易脱落，导致活动件无法封堵排水口，从而发生滴水、漏水的现象。
有鉴于此，特提出本发明。

如图21至图23所示，本实施例中介绍了一种滚筒洗衣机的密封排水装置，滚筒洗衣机包括洗涤衣物时独立盛放洗涤水的内筒17，内筒17上开设排水口39，密封排水装置包括：封堵部件，与排水口39密封接触封堵所述排水口39；封堵部件可以利用自身、或安装密封件40对排水口39对应封闭处理，排水口39处的内筒壁设有向内筒17外侧弯折的折边48，封堵部件或密封件40与折边48相密封接触以封堵排水口39。
本申请的密封排水装置通过封堵部件封堵排水口39，实现了具有无孔内筒的滚筒洗衣机在洗涤、漂洗时保持排水口39封闭，实现无孔内筒独立盛水。
本实施例中，封堵部件包括一与内筒壁相密封接触、以封闭排水口39的密封件40；优选的，密封件40与内筒壁、和/或折边39产生相互挤压而产生弹性变形，利用弹性变形对二者相接处进行密封。

通过在封堵部件上设置密封件，利用随封堵部件共同移动、且独立设置的密封件与内筒壁相接触，并利用接触过程的挤压力对相接处进行密封处理，不仅提升了密封性能、还优化了装置的安装提升了装配和维护速率；同时，将密封件设置可相对伸缩移动的封堵部件上，使得密封件所承受的夹持的密封力增大、令密封效果显著提升。
本实施例中，密封件40与内筒17壁产生相互挤压而产生弹性变形，利用弹性变形对二者相接处进行密封。为了实现利用弹性变形对密封件和内筒之间进行密封的效果，可以将密封件40自身由弹性材质构成；当然也可以将与密封件40相对应接触的内筒17壁部分设置为由弹性材质构成，以利用密封件40和/或内筒17壁的弹性变形进而实现密封接触。
