在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
下面结合附图1-4具体描述根据本发明实施例的洗衣机内筒100。
如图1至图4所示，根据本发明实施例的洗衣机内筒100包括：本体10。其中，洗衣机内筒100大体为一个上下贯通的筒状件，本体10内限定出洗涤腔室11，也就是本体10的内部空间为洗涤腔室11，衣物可以在洗涤腔室11内洗涤。本体10的周壁上设有洗涤区20，洗涤区20上具有多个洗涤单元30。每个洗涤单元30由3个子单元组成，其中，每相邻两个子单元具有共用边缘，每个洗涤单元30朝向远离洗涤腔室11向外凸出且共用边缘的相交处为最低处52，这样可以增强洗衣机内筒100的结构强度和刚度，洗衣机内筒100不容易发生变形，洗衣机内筒100的结构更加稳定；并且，在共用边缘上具有至少一个脱水孔，可以增大与衣物的接触面积及脱水面积，从而提高洗衣机的洗涤效果洗净比。也就 是说，其中每相邻两个子单元共用一部分边缘，如图3所示，也就是每两个子单元的其中一部分边缘相互重合。每个洗涤单元30朝向远离洗涤腔室11向外凸出且共用边缘的相交处为最低处52，即形成为尖端，以使洗涤单元30的顶端凸出于洗衣机内筒100的内壁面，该尖端可以为点状、线状、平面状或者曲面状。
由此，根据本发明实施例的洗衣机内筒100，通过在洗衣机内筒100的本体10上设置由多个洗涤单元30组成的洗涤区，并且洗涤单元30朝向远离洗涤腔室11向外凸出，每个洗涤单元30由三个子单元组成，从而可以增强洗衣机内筒100的结构强度和刚度，洗衣机内筒100不容易发生变形，洗衣机内筒100的结构更加稳定，同时洗涤单元30中每相邻两个子单元之间的相交处为最低处52，即尖端凸出于洗衣机内筒100的内壁面，可以增大与衣物的接触面积，从而增强衣物与洗衣机内筒100之间的摩擦力；并且在每相邻两个子单元的共用边缘上设有多个脱水孔，可以增加脱水面积，提高洗衣机的洗涤效果洗净比。
在本发明的一些实施例中，在共用边缘上的最低处52，及远离最低处52的边缘上具有至少两个脱水孔，这样可以增大与衣物的接触面积及脱水面积，从而提高洗衣机的洗涤效果洗净比。由此，在多个洗涤单元30的共用边缘上设置脱水孔增加了洗衣机内筒100的脱水面积，提升了洗衣机内筒100的脱水效果。
可选地，如图3所示，在共用边缘上的最低处52，以及在共用边缘上与最低处52间隔开的次低处51(53、54)上共设有四个脱水孔。具体地，次低处51(53、54)与本体10的轴线12的距离大于最低处52与本体10的轴线12之间的距离。
在本发明的一个具体实施方式中，洗衣机内筒100上设有多个沿其周向间隔开设置的洗涤区20。当然，在洗衣机内筒100的整个周壁上可以只设置一个洗涤区20，也就是在洗衣机内筒100的周壁上都设有由洗涤单元30组成的洗涤区20。可选地，洗涤区20的形状为矩形，如图1和图2所示，也就是将弧形曲面的洗涤区20展开成平面时，展开后的洗涤区20的形状大致为矩形，或者洗涤区20在经过洗衣机内筒100的轴线12的基准面上的投影为矩形。可以理解的是，洗涤区20的形状还可以为多边形、圆形等规则的图形，或者其它不规则的图形。
多个洗涤单元30在洗衣机内筒100上的排列分布没有特殊限制。如图1，在本发明较佳实施例中，多个洗涤单元30在洗衣机内筒100上按照蜂窝状顺序排列。由此，多个蜂窝状排列的洗涤单元30会产生立体正方形的效果。如图3所示，在本发明一个较佳的实施方式中，洗涤单元30的形状为六边形。具体地，如图3所示，将洗衣机内筒100展开成平面时，洗涤单元30的形状为六边形，多个洗涤单元30分布在洗涤区20上。
优选地，洗涤单元30的形状为正六边形，具体地，将洗衣机内筒100展开成平面，洗涤单元30在展开后的洗衣机内筒100上的形状大致为正六边形，或者洗涤单元30在经过洗衣机内筒100的轴线12上的基准面上的投影大致为正六边形。
可选地，洗涤单元30的共用边缘形成为曲线形边缘。换言之，每个洗涤单元30的边缘不仅可以由直线构成，也可以由曲线构成，从而当多个洗涤单元30分布在洗涤区20时，每相邻两个子单元的共用边缘为曲线形边缘。
可选地，如图3，洗涤单元30向外凸出形成三棱锥形，且共用边缘朝向共用边缘的相交处倾斜延伸。将洗衣机内筒100展开成平面，洗涤单元30大致为三棱椎形，可以增加洗衣机内筒100的结构强度和刚度。
根据本发明实施例的洗衣机(未示出)，包括上述实施例的洗衣机内筒100。由于根据本发明上述实施例的洗衣机内筒100具有上述的技术效果，因此根据本发明实施例的洗衣机也具有相应的技术效果，即：洗衣机内筒100的结构稳定性高，不容易发生变形，并且洗衣机的洗涤效果和脱水效果更好。
根据本发明实施例的洗衣机的其它结构以及操作属于本领域普通技术人员容易理解并获得的，在此不再进行赘述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
