参见图1至图4，本申请实施例提供一种内筒组件，包括内筒体10和提升筋20，提升筋20设置于内筒体10的内壁上，提升筋20包括提升筋本体21，提升筋本体21上设置有多个过水孔22，提升筋本体21的外表面设置有导水曲面，导水曲面的至少一部分为最速降线曲面，内筒体10中的水能够沿导水曲面流进过水孔22。
在内筒转动过程中，提升筋本体21从低处转动到高处将水提升，部分水从导水曲面流到衣物上，部分水从导水曲面流到过水孔22中，由于导水曲面的至少一部分为最速降线曲面，最速降线曲面基于最速降线原理设置，能够加快液体的流速，使得水流速度大，对衣物的冲击力大，洗涤效果好。
过水孔22具有进口端和出口端，沿进口端至出口端的方向，过水孔22的截面积逐渐减小，导水曲面设置于进口端。水流沿导水曲面从过水孔22的进口端流入，再从过水孔22的出口端流出，由于沿进口端至出口端的方向，过水孔22的截面积逐渐减小，因此水流在通过过水孔22的过程中产生气泡，在内筒转动过程中，提升筋本体21随着内筒体10转动，水流不断流入过水孔22产生气泡，使得微气泡全程覆盖洗涤过程，提升洗涤效率。
在本实施例中，进口端和出口端分布于提升筋本体21的两侧，使得过水孔22沿轴向具有预设长度，便于产生气泡。在一实施例中，提升筋本体21的底端 与内筒体10连接，进口端和出口端分布于提升筋本体21的两个相对的侧面上。
提升筋本体21的底端与内筒体10连接，提升筋本体21的顶端可以呈弧形设置，以防刮伤衣物。提升筋本体21的一侧表面设置有第一导水曲面201，第一导水曲面201的至少一部分为最速降线曲面，第一导水曲面201自内筒体10的内壁面向远离内壁面的方向延伸。在一实施例中，在内筒体10转动过程中，水流从第一导水曲面201的一侧流向另一侧，因此第一导水曲面201的第一侧与内筒体10的内壁面相接，第一导水曲面201的第二侧至少延伸至提升筋本体21上的过水孔22的位置，使得水流顺利流进过水孔22中。
在本实施例中，提升筋本体21沿一直线延伸，直线平行于内筒体10的轴线，最速降线曲面是由一条轮廓线沿直线延伸形成的曲面，轮廓线为最速降线曲线。在一些实施例中，提升筋本体21也可以沿曲线延伸。
根据最速降线原理，如图5所示，设O、A是高度不同且不在同一铅垂线上的两定点，如果不计摩擦和空气阻力，一质点m在重力作用下从O点沿一曲线降落至A(p，q)点，沿着最速降线滑下所需时间最短，因此最速降线曲面具有最快的排水速度。
过水孔22的设置采用以下至少一种形式：可以设置于导水曲面的底端，及过水孔22设置于导水曲面上。在本实施例中，在第一导水曲面201的底端和第一导水曲面201上分别设置有过水孔22，以加快过水速度。
两个提升筋本体21组成一个提升结构，多个提升结构绕内筒体10的周向间隔设置，每个提升结构中的两个提升筋本体21相对于一中间平面对称设置，中间平面过内筒体10的轴线。提升结构的设置，使得无论内筒体10沿顺时针旋转还是沿逆时针旋转，都有对应的提升筋本体21起到作用，提高水流速度，使得微气泡覆盖整个洗涤过程，提高洗涤效率和洗涤效果。
实施例二
图6至图9示出了实施例二，其中与实施例一相同或相应的零部件采用与实施例一相应的附图标记。为简便起见，仅描述实施例二与实施例一的区别点。区别之处在于，提升筋本体21弯折呈弧形结构，弧形结构的凹陷方向平行于内筒体10的转动方向，自弧形结构的端部至弧形结构的中间位置形成弧形导水曲面202，弧形导水曲面202的至少一部分为最速降线曲面。
由于水流能够沿最速降线曲面迅速汇聚至弧形结构的凹陷位置，以较大的速度进入过水孔22中，使汇聚起来的水流压力值达到最大，进而在洗涤的过程 中能够产生足够的水压将逐渐减小的过水孔22中的空气挤出，进而在洗涤过程中持续产生气泡；当提升筋本体21转动至内筒体10的高处，在空气中旋转时，可以运用相同的原理，通过空气压力和离心力将过水孔22中的水排出，最终实现循环，同时可以通过设置洗涤程序在洗涤转速提高的基础上，产生更小气泡，进一步提高洗涤过程中衣物洗净比。
在一实施例中，提升筋本体21的底端与内筒体10连接，弧形结构的凹陷处位于提升筋本体21的一个侧面上。
多个过水孔22的分布，自提升筋本体21的两端向中间逐渐密集，使得更多的水从提升筋本体21的中间位置流出，水流速度较快。
过水孔22的进口端形成蓄水槽24，蓄水槽24的内壁形成弧形导水曲面。弧形导水曲面的至少一部分为最速降线曲面，加快水流速度，使得水流迅速进入过水孔22。同时，借助蓄水槽24的蓄水能力，使得提升筋本体21在从低处到高处转动的过程中，能够提升更多的水，增强洗涤效果。
实施例三
图10至图13示出了实施例三，其中与实施例一相同或相应的零部件采用与实施例一相应的附图标记。为简便起见，仅描述实施例三与实施例一的区别点。区别之处在于，提升筋本体21的内部中空形成蓄水腔，过水孔22与蓄水腔连通，提升筋本体21的内表面设置有第三导水曲面203，第三导水曲面203的至少一部分为最速降线曲面，蓄水腔中的水能够沿第三导水曲面203流出过水孔22。最速降线曲面基于最速降线原理设置，能够加快液体的流速，使得水流速度大，提升筋本体21里的水经过最速降线曲面从过水孔22流出，具有初速度，对衣物的冲击力大，洗涤效果好。
沿第三导水曲面203上的水流的流动方向，过水孔22设置于第三导水曲面203的底端。从导水曲面上流下来的水经过最速降线曲面能够快速进入到过水孔22中。过水孔22也可以设置于第三导水曲面203上，提高排水效率。
在一实施例中，提升筋本体21的内表面设置有第三导水曲面203，第三导水曲面203包括至少两个最速降线曲面，每个最速降线曲面绕提升筋本体21的周向设置。一般情况下，提升筋本体21设置成长条状，根据提升筋本体21的形状设置第三导水曲面203的位置，当设置两个最速降线曲面时，两个最速降线曲面可以沿提升筋本体21的长度方向延伸。在本实施例中，提升筋本体21的内表面具有四个最速降线曲面，每个最速降线曲面绕提升筋本体21的周向依次相连。
如图12所示，第三导水曲面203相对于提升筋本体21的内壁凹设。在一实施例中，提升筋本体21的内部形成蓄水腔，导水曲面相对于蓄水腔的内壁凹设。当提升筋本体21转动到高处时，提升筋本体21里的水经过最速降线曲面从过水孔22流出，水沿最速降线具有初速度，对衣物的冲击力大，洗涤效果好。
提升筋本体21的外表面设置有第四导水曲面204，可以是如图12所示，第四导水曲面204相对于提升筋本体21的外壁凸设。也可以是如图13所示，第四导水曲面204相对于提升筋本体21的外壁凹设，第四导水曲面204的至少一部分为最速降线曲面。当水经过提升筋本体21的表面时，能够沿着最速降线曲面流动，流动速度快，提高洗涤效率。
当第四导水曲面204相对于提升筋本体21的外壁凹设，提升筋本体21随着内筒体10转动到低处时，水能够沿着提升筋本体21的第四导水曲面204迅速向下流动，以实现快速排水；第三导水曲面203相对于提升筋本体21的内壁凹设，当提升筋本体21随着内筒转动到高处时，提升筋本体21中的水能够沿着第三导水曲面203迅速向下流动，以实现快速喷淋。
沿第四导水曲面204上的水流的流动方向，过水孔22设置于第四导水曲面204的底端。在一实施例中，过水孔22设置于第四导水曲面204。
实施例四
图14至图16示出了实施例四，其中与实施例一相同或相应的零部件采用与实施例一相应的附图标记。为简便起见，仅描述实施例四与实施例一的区别点。区别之处在于，在内筒体10的内壁上设置内筒导水曲面101，内筒导水曲面101的一侧与第一导水曲面201连接，内筒导水曲面101的至少一部分为最速降线曲面，使得水流迅速从内筒体10流到提升筋20。在一实施例中，内筒导水曲面101与第一导水曲面201沿同一个最速降线曲面延伸，使得水流速度更快。
提升筋本体21凸设于内筒体10的内表面上，内筒体10与提升筋本体21可拆卸连接。具体可以是卡接。参照图10，提升筋20还包括设置于提升筋本体21上的卡扣23，卡扣23可以与内筒体10上的卡孔卡接。在一实施例中，提升筋本体21与内筒体10之间可以通过螺钉锁紧，以使得连接稳固。
内筒体10的内表面凹设有安装槽111，提升筋本体21与安装槽111连接，内筒体10与安装槽111的交界处形成导水曲面，能够加快液体的流速，实现快速排水，避免水分残留，进而避免细菌和异味。内筒体10通过冲压成型，在内部形成安装槽111的同时，对应的外部位置形成凸起，内筒体10与凸起的交界处形成 导水曲面，能够加快液体的流速，实现快速排水，避免水分残留，进而避免细菌和异味。
在本实施例中，内筒体10包括筒本体11、前端板12和后端板13，内筒体10的内表面于筒本体11与前端板12的连接处，及内筒体10的内表面于筒本体11与后端板13的连接处分别形成导水曲面。导水曲面是由一条轮廓线绕筒本体11的中心线旋转设定角度得到的曲面，轮廓线为最速降线曲线。其中，设定角度大于0度且小于等于360度。在本实施例中，设定角度为360度，最速降线曲面是一个周向的曲面。
内筒体10的内表面于筒本体11和前端板12的连接处形成的导水曲面为前端导水曲面102。前端导水曲面102使得前端板12上的水能够迅速向下流动，避免前端板12的内表面有水残留，同时避免筒本体11和前端板12的连接处有水残留。
内筒体10的内表面于筒本体11与后端板13的连接处形成的导水曲面为后端导水曲面103。后端导水曲面103使得后端板13上的水能够迅速向下流动并流至内筒体10中，进而可以从内筒体10上的孔排出，避免后端板13的内表面有水残留，同时避免筒本体11和后端板13的连接处有水残留。
前端板12上设置有投放口，投放口处向远离后端板13的方向凸设有凸缘121，凸缘121绕投放口的周向设置，凸缘121与前端板12的连接处形成导水曲面，导水曲面的至少一部分为最速降线曲面，最速降线曲面基于最速降线原理设置，能够加快液体的流速，实现快速排水，避免投放口处水分残留，进而避免细菌和异味。
