具体实施方式
实施例1
如图1-3所示，本实施例提供了一种滚筒洗衣机，该滚筒洗衣机不需要定期清洗洗涤筒外壁或内壁上的污垢，同时还能更为省水。该滚筒洗衣机包括洗衣 机外壳1，洗衣机外壳1内设置有洗衣滚筒用于转动清洗衣物，洗衣滚筒包括洗涤前筒21和洗涤后筒22，其中洗涤前筒21与洗涤后筒22动态密封连接，且洗涤前筒21相对洗涤后筒22可转动，洗涤前筒21转动过程中洗涤后筒22静止，进而能够保证洗衣滚筒内的水随着洗涤前筒21转动，起到洗涤衣物的作用；洗涤前筒21通过皮带3与电机4相连，且洗涤前筒21可随电机4转动，即皮带3随电机4转动而转动，电机4带动洗涤前筒21转动时，洗涤后筒22静止，由于洗涤后筒22静止，注水和排水均无需定位，因此，本实施例中洗涤后筒22上设置有进水孔221和出水孔222，出水孔222通过排水连接管5与排水阀51相连。洗涤完成后，污水通过出水孔222和排水阀51进入排水管52排出洗衣机外。
为了使洗衣滚筒内的水随洗涤前筒21转动，本实施例中洗涤后筒22长度h小于洗涤前筒21长度H。其中洗涤后筒22长度可以尽可能的小，但是需要注意的是，该洗涤后筒22的长度应不影响设置出水孔222和进水孔221。该洗涤后筒22可以通过弹簧或减震器柔性的固定在洗衣机外壳1内，也可以是完全硬性的牢牢的固定在洗衣机外壳1内。
本实施例中洗涤后筒22以及洗涤前筒21均为无孔结构筒，即洗涤后筒与洗涤前筒的侧壁上均没有设置孔，而洗涤后筒22上设置有进水孔221和出水孔222。该种结构能够保证洗涤前筒21在旋转后无需进行定位就能够注水或排水。能够防止水从侧壁孔流出引起桶壁污垢堆积，还能够省水。同时洗涤前筒22与洗涤后筒21筒外不会有水浸泡，进而使洗涤前筒21旋转过程中不会受到孔内通过的水的阻力，使旋转更顺畅。
同时洗涤前筒21为无孔结构筒，进水完成后，排水泵或者排水阀未启动处于密封状态，洗涤剂及洗涤水都密封存在洗涤前后筒内，洗涤衣物也放置于洗涤前后筒内。该种结构能够实现盛水筒和盛衣物筒为一体设计，防止水流出洗涤筒外壁导致外壁积累污垢，同时还能够省水。
洗衣机外壳1一侧设置有投入口，投入口处设置有门窗8，洗涤前筒21靠近门窗8的一侧还设有密封门7用于密封洗衣滚筒，密封门7与洗涤前筒21铰接连接，进而能够保证密封门7打开。洗涤前筒21与密封门7相接触的侧壁或密封门7与洗涤前筒21相接触的侧壁上设置有密封凹槽212，密封凹槽212内设置有第一密封圈61(参考图2)。进而使密封门7关闭后与洗涤前筒21之间能够实现静态密封，确保洗涤滚筒无漏水问题。用户打开门窗8，再打开密封门 7，即可实现洗涤衣物取放。
当然其他实施例中还可以是密封门7与门窗8连接，且密封门7相对于门窗8可转动，即密封门7与门窗8通过轴连接，密封门7能够将洗涤前筒21前端封堵，使密封门7和洗涤前筒21二者形成密封腔室，防止洗涤水流出。这样打开门窗8可以一起打开密封门7，进而实现洗涤衣物取放，使用户使用洗衣机更为方便。
上述洗涤前筒筒21内侧壁上设置有至少一根的提升筋211。设置提升筋211的目的是在洗涤过程中将衣物通过提升筋提升后再急速降落，使得内部的衣物更好的被提高跌落摔打洗涤。
为了保证洗涤后筒22与洗涤前筒21能够相对转动，本实施例中洗涤后筒22与所述洗涤前筒21通过转动轴承10连接，其中所述洗涤后筒22套设于所述转动轴承10内圈，所述洗涤前筒21与所述转动轴承10外圈配合，所述洗涤前筒21与所述洗涤后筒22之间设置有第二密封圈62。
如图3所示，为了防止洗涤前筒21与洗涤后筒22之间的连接处发生漏水，所述洗涤前筒21与所述洗涤后筒22的连接处设置有截面为F形的限位环213；其中，所述限位环213包括第一竖直限位环体2131、设置于所述第一竖直限位环体2131顶部的第一横向限位环体2132以及与所述第一横向限位环体2132平行设置的第二横向限位环体2133；所述第二密封圈62设置于所述第一横向限位环体2132与所述第二横向限位环体2133之间，所述转动轴承10设置于所述第一竖直限位环体2131、第二横向限位环体2133以及洗涤后筒22外壁组合形成的空间区域内。所述第二密封圈62为唇形密封圈。限位环213与洗涤前筒21为一体式结构，该种结构能够使得洗涤前筒21与限位环213之间密封性更佳。
洗涤前筒21与洗涤后筒22通过转动轴承10连接，能够有效的保证洗涤前筒21相对于洗涤后筒22旋转，同时洗涤后筒22与洗涤前筒21之间设置有密封圈，能够防止洗衣滚筒内的水流出滚筒外而影响洗衣机工作。
洗涤前筒21在旋转时，处于低速洗涤时，转速在0-200转/分钟；处于高速脱水甩干时，转速在600-1800转/分钟。上述第二密封圈62可以为唇型密封圈，该种密封圈具有自密封作用，依靠工作压力作用唇部，使得唇部压紧密封耦合面，而且能够自动补偿磨损量。上述工作压力来源于洗涤前筒21与洗涤后筒22的预压紧力、洗涤前筒21自身重力以及内部液体的工作压力。第二密封圈62种类可以是Y型、V形、U形、J形或L形。
洗涤前筒21与洗涤后筒22的转动连接(动态连接)为轴承连接，洗涤前筒21与洗涤后筒22分别连接了轴承外圈和内圈，其中转动轴承可挑选的种类多种多样，上述转动轴承9包括所有轴承，如球轴承、滚子轴承。本实施例中轴承类型可以为圆锥滚子轴承、圆柱滚子轴承或圆珠滚子轴承等。本实施例中选用圆锥滚子轴承，其中该圆锥滚珠轴承包括轴承内圈、轴承支架、圆锥滚子和轴承外圈。
如图1所示，该滚筒洗衣机注水时通过洗衣机外壳1上设置的进水阀92进入洗衣机内，其中进水阀92连接自来水管路，所述进水阀92通过进水管道93与洗涤剂盒9连接，所述洗涤剂盒9通过注水管91与所述进水孔221连接。自来水依次通过进水阀92、进水管道93和洗涤剂盒9后进入洗涤后筒22内。
该洗衣机外壳1的底部还设置有底盘12，底盘12底部设置有用于支撑洗衣机整体的地脚13，洗衣机外壳1顶部设置有上台面板14。
实施例2
本实施例中与实施例1不同之处在于，洗衣滚筒中心轴线相对于水平面倾斜设置。
如图4所示，为了实现取放衣物方便，其中，洗衣滚筒中心轴线与水平面倾斜设置，洗衣滚筒中心轴线与水平面的夹角为α，且0≤α＜90°。
图5所示，该实施例中转动轴承10为圆柱滚子轴承。当然其他实施例中还可以为球轴承(参考图6)。
工业实用性
本公开的滚筒洗衣机，不需要定期清洗洗涤筒外壁或内壁上的污垢，且更加省水。
