Description

滚筒洗衣机的内筒及滚筒洗衣机
本申请要求在2019年3月13日提交中国专利局、申请号为201910189918.8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内筒及滚筒洗衣机。
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，比如申请号为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，密封件容易脱落，导致无法封堵排水口，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内筒，包括：一实体壁围绕形成的容纳空间，配置为独立地盛放洗涤水；至少一个排水口，所述至少一个排水口设置在所述实体壁上，配置为从内筒中排出水，所述排水口的外周区域的实体壁上设置有密封部。
本申请还提供了一种滚筒洗衣机，包括：上述的内筒；封堵部件，设置于所述内筒的排水口处，配置为与所述内筒上的所述密封部相配合，以对所述排水口进行封堵或打开。

本实施例中，封堵部件包括一与内筒17的实体壁相密封接触、以封闭排水口的密封件40。
本实施例中，密封件40与内筒17的实体壁上所设密封部产生相互挤压而 产生弹性变形，利用弹性变形对二者相接处进行密封。密封件40可以由弹性材质构成，密封件40与密封部在相互挤压后自身产生弹性变形以对相接处进行密封。
本实施例中，内筒17壁上安装有对应扣合于排水口39处的提升筋32，提升筋32内部中空并通过提升筋32上的开孔与内筒17内部相连通，内筒17壁上设置的排水口39与提升筋32中空部相连通，排水口39处设置的封堵部件处于提升筋32内部。
实施例七
本实施例基于上述实施例六还具有如下技术特征：为了实现密封排水装置的封堵部件与排水口39处内筒壁密封接触，在排水口39处的内筒壁设有以下至少之一的结构：向内筒17外侧弯折的折边48和排水口39内壁向内筒17外侧延伸的挡筋，所述折边和挡筋至少之一呈筒形或锥形，以使封堵部件自身和封堵部件上安装的密封件40与折边48和挡筋至少之一密封接触，进而实现对排水口39的封闭处理。
如图21至图23中的折边48可以是图6至图8中的延伸壁48的另一种形式。
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，配置为与排水口39密封接触封堵所述排水口39；封堵部件可以利用自身或在封堵部件上安装密封件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；密封件40与内筒壁和折边48至少之一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。
本实施例中，密封件40还包括密封件一侧设置的且向排水口侧凸出的凸出部47，凸出部47的至少部分沿凸出部的轴向凸出于排水口39，使凸出部47与 排水口39处的折边48相对密封贴合。凸出部47直径呈向远离封堵部件侧逐渐减小的且与排水口39同轴设置的锥形，且锥形凸出部47的最小端直径小于排水口39的直径，且锥形凸出部47最大端直径大于排水口39的直径，以使凸出部47可对应伸入排水口39处的折边48中，令凸出部47与折边48之间直接挤压变形而对接触处进行密封处理。同时，为了保证二者之间的密封接触，需要将凸出部47的大口端直径设置为大于锥形折边48的大口端直径。
如图21至图23中的凸出部47可以是图6至图8、图13和图15中中的第一密封部件47的另一种形式。
本实施例中还介绍了一种滚筒洗衣机的内筒结构，内筒17包括实体壁围绕形成的容纳空间，配置为独立地盛放洗涤水；至少一排水口39，所述排水口39设置在所述内筒17的实体壁上，内筒中的水通过所述排水口39排出；排水口39外周区域的实体壁上设置有第一密封部、排水口39的内壁处设有第二密封部。
本实施例中的第一密封部为上述实施例三中所述的在内筒17实体壁上设置排水口处的密封凸部41；第二密封部为本实施例中所述的在内筒17排水口39处设置的向筒外方向延伸的筒形或锥形的折边48和/或挡筋。
当然本实施例中在保证内筒密封的前提下可以在第一密封部和第二密封部之间则一选择的设置。

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壁之间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和内筒17壁的至少之一的弹性变形进而实现密封接触。
