Description

滚筒洗衣机的密封排水装置及滚筒洗衣机
本申请要求在2019年3月13日提交中国专利局、申请号为201910189956.3的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及洗衣设备技术领域，例如涉及一种滚筒洗衣机的密封排水装置及滚筒洗衣机。
背景技术
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，例如申请号为201410215346.3、名称为“一种滚筒洗衣机”的中国专利申请，该申请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，该申请的内筒为无孔内筒，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，节约了洗涤用水量。
上述申请提供了一种具有无孔内筒的滚筒洗衣机，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，该申请公开的滚筒洗衣机进水的方式是通过门封，由于门封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，相关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。
发明内容
本申请提供了一种滚筒洗衣机的密封排水装置，所述滚筒洗衣机包括洗涤衣物时独立盛放洗涤水的内筒，内筒上开设排水口，其中，密封排水装置包括：
封堵部件，与排水口密封接触，配置为封堵所述排水口；
所述的封堵部件设置有沿封堵部件中心轴线的多个截面积不相等的横截面的第一密封部件，第一密封部件的至少一个横截面的外周壁配置为与排水口周向密封接触以封堵排水口。
本申请还提供了一种滚筒洗衣机，包括：
内筒，配置为洗涤衣物时独立盛放洗涤水；
排水口，开设在内筒上，配置为排放洗涤水；
上述的密封排水装置，安装在内筒的内壁上，密封排水装置中的封堵部件配置为，当内筒的转速达到设定值V0时，打开所述排水口。
