Description

一种滚筒洗衣机 技术领域
本发明属于家用电器领域，具体地说，涉及一种滚筒洗衣机。
背景技术
滚筒洗衣机包括内筒和外筒，内筒和外筒之间存在间隙，在洗衣机长期使用后间隙内会产生洗涤污垢，洗涤污垢堆积在内筒外壁和外筒内壁上，会产生细菌危害用户的健康，降低洗衣机的洗衣效率和衣物洗涤后的洗净度。由于内外筒相互套装，用户无法对内筒外壁和外筒内壁进行清洁，只有将内筒进行拆卸才能清洗，操作困难。为解决问题，很多洗衣机厂商在滚筒上提供了筒自洁功能，一般是在桶内注入较多水并进行加热，同时内筒进行高于50rpm的旋转，虽然达到了一定的清洁效果，去不能完全去除堆积在内筒外壁和外筒内壁上的污垢。
人们提出无孔洗衣机，内筒中既能盛水和衣物，又能旋转对衣物进行翻转洗涤，但是内筒中的水会由投放口处溅射到外筒敞口处，采用无孔内筒后如何实现进水和排水也是需要解决的问题。
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，提供一种滚筒洗衣机，在外筒和内筒的开口处设置联动的门体，其目的在于将内筒投放口进行密封，防止内筒中的水自投放口溅射在内筒和外筒之间。
为解决上述技术问题，本发明采用技术方案的基本构思是：

进一步，所述第二门体关闭投放口后与内筒相密封、并固定连接，第二门体相对于第一门体可相对旋转。
进一步，所述第二门体关闭投放口后与内筒可相对转动的密封连接。
进一步，第一门体的外围和外筒敞口之间设有用于密封和起缓冲作用的第一密封圈，第二门体的外围和内筒投放口之间设有第二密封圈。
进一步，所述联动机构包括相互配合插接的第一连接端和第二连接端，所述第一连接端由第一门体的中心向第二门体一侧凸出延伸，所述第二连接端由第二门体的中心向第一门体一侧凸出延伸，第一连接端和第二连接端插接固定；优选的，第一连接端和第二连接端可转动的相插接连接，插接连接处的转动轴与投放口同轴设置。
进一步，所述第一连接端为圆柱体，第二连接端为一开口的凹槽，所述开口朝向第一门体，所述圆柱体自开口对应插入至凹槽内。
进一步，所述第一连接端为一开口的凹槽，所述开口朝向第二门体，第二连接端为圆柱体，所述圆柱体自开口对应插入至凹槽内。
进一步，第一连接端和第二连接端之间安装滚动装置。
进一步，第一门体包括相平行连接的前板和后板，所述前板对应封闭外筒的敞口，所述后板设置在前板和第二门体之间，后板相对于前板可产生前后位移，后板上朝向第二门体的一侧设置第一连接端。
进一步，所述前板和后板之间具有一定的间隙，前板和后板之间安装有沿投放口轴向方向延伸的弹簧，弹簧的两端分别与前板和后板相连接；优选的，前板和后板的外周之间设有可产生伸缩变形的伸缩管，伸缩管的两端分别与前板和后板的外周相密封固定连接。
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。
1、外筒敞口和内筒投放口处设置联动的门体，保证了内筒的密封性，在第一门体关闭、或打开时，同时带动第二门体关闭、或打开，实现内筒外同时关闭、打开，避免在洗涤过程中内筒中的水由投放口溅射出来，实现了洗衣机免清洗的目的。
2、第二门体可相对第一门体旋转，在关闭后，第二门体随内筒一起旋转，第一门体和第二门体不影响内筒转动实现洗涤、脱水功能，且结构简单。
3、第一门体的外围和外筒敞口之间设有密封圈，密封圈即可以对外筒敞口进行密封，在门体关闭时还可以缓冲门体对洗衣机的冲击力，密封圈代替了原来滚筒洗衣机中的窗垫，结构简单，便于清洗。
