技术领域
本发明涉及洗衣技术领域，具体提供一种提升筋、滚筒组件与洗涤设备。
背景技术
滚筒洗衣机在洗涤衣物时，滚筒内的提升筋带动衣物上升，当衣物接近滚筒顶部时，由于重力作用，衣物跌落至桶底，如此反复摔打，就如同人工捶打的洗衣方式。
但是衣物在滚筒转动中的过程中，受到离心力和翻滚的影响，衣物会持续撞击滚筒开口处的封闭门窗。这将会造成破坏洗衣机封闭门窗密封性和结构强度的问题。
因此，本领域亟需一种提升筋、滚筒组件和洗涤设备来解决上述问题。
发明内容

为解决在滚筒洗衣机洗涤过程中，衣物撞击滚筒开口处门窗的问题。
下面结合三个实施例对本技术方案的具体实施方式进行介绍。
第一实施例：
本实施例公开了一种洗涤设备，其具体为一种滚筒洗衣机，其主要用来洗涤衣物，也可以用来洗涤其他洗涤对象。
如图1和图2所示，该洗涤设备包括滚筒组件。滚筒组件包 括滚筒2和设置在滚筒2中的提升筋1。
滚筒2为圆筒状；滚筒2的一端设置有开口21，用于放入或取出衣物；滚筒2中与开口21相对的另一端为滚筒2的内端面22。在滚筒2的开口21处，洗涤设备设置有封闭门窗(图中未示出)，用于在洗涤衣物时，封闭滚筒2的开口21。
提升筋1设置在滚筒2的内侧壁上，在本实施例中，3个提升筋1在滚筒2的内侧壁的圆周方向上均匀设置；在其他实施例中，设置不同数量的提升筋1，以及不同的提升筋1的位置关系亦可。
参照图3，提升筋1向滚筒2的内部凸起，呈长条状。其长度方向(图3的上下方向)上的第一端12靠近滚筒2的开口21，第二端13靠近滚筒2的内端面22。且其长度方向与滚筒2轴向平行。提升筋1上靠近滚筒2轴线的一面为提升筋1的顶部19，顶部19的两侧为提升筋1的侧面。从提升筋1的顶部19到滚筒2的内侧壁的垂直方向为提升筋1的高度方向(图4和图5的上下方向)。
参照图3至图6，提升筋1的两侧面分别设有驱动曲面11。当洗涤设备进行洗涤时，滚筒2转动，提升筋1随滚筒2转动，提升筋1将衣物挑起，使提升筋1上部的驱动曲面11与衣物接触，驱动曲面11能够驱动衣物向滚筒2内部移动，从而使衣物远离滚筒2的开口21，避免衣物撞击封闭门窗。并且提升筋1的两侧分别设有驱动曲面11，无论滚筒2正转还是反转，都有一个驱动曲面11能够驱使衣物移动到滚筒2内部。具体地，驱动曲面11从第一端12向第二端13延伸的过程中，向提升筋1内部倾斜，以使衣物沿驱动曲面11的倾斜方向滑动至第二端13，即滚筒2内部。
进一步地，参照图4至图5，在提升筋1的高度方向上，驱动曲面11向提升筋1内部凹陷(即图4和图5中的水平方向)；也即在垂直于提升筋1长度方向的截面上(如图5的剖面图所示)，驱动曲面11向提升筋1内部凹陷，用于增大驱动曲面11的表面积，以便与衣物接触，驱动衣物移动。
参照图5，提升筋1内部中空，形成空腔16。提升筋1的顶部19设有喷淋孔14，提升筋1的两侧设有透水孔15，喷淋孔14与透水 孔15均连通空腔16与滚筒2内部。当洗涤设备进行洗涤时，滚筒2内的水会通过透水孔15进入空腔16；当提升筋1随滚筒2转动到滚筒2上半部时，空腔16中的水会从喷淋孔14喷出，对滚筒2内的衣物形成喷淋效果。
继续参照图5，喷淋孔14和透水孔15的轴线与滚筒2转动时提升筋1转动的切线方向(图5中的箭头A指向的方向)之间呈35度至55度的夹角，优选地为45度夹角。在洗涤衣物时，衣物上的线头、毛屑和其他杂质会随水流进入喷淋孔14与透水孔15，并停留在空腔16中。通过设置上述角度，使水流流出喷淋孔14与透水孔15时，杂质易于随水流流出空腔16，避免杂质积累在空腔16中。
进一步地，滚筒2、提升筋1、喷淋孔14与透水孔15满足公式(a)示出的条件时，转动至滚筒2上半部的提升筋1上的喷淋孔14能够全程喷淋，即提升筋1在滚筒2上半部180度的角度范围内，其上的喷淋孔14均能够进行喷淋。公式(a)如下所示：
公式(a)中，V为空腔16中存水的有效体积，S为所有喷淋孔14与所有透水孔15之和的等效面积，g为重力加速度，n为滚筒2的转速，r为滚筒2的半径，为提升筋1的离心力与重力的夹角，h为喷淋孔14与空腔16中水面的距离，t为空腔16中水完全流出的所需时间。
更进一步地，参照图3，提升筋1上设有多个喷淋孔14，多个喷淋孔14沿提升筋1长度方向排列为两排。为了使两排喷淋孔14能够同时喷淋，滚筒2需要满足公式(a)和公式(b)示出的条件。公式(b)如下所示：
公式(b)中，n为滚筒2的转速，g为重力加速度，r为滚筒2的半径。
进一步地，提升筋1的外表面设有凸起，以便增大提升筋1与衣物之间的摩擦力。具体地，凸起包括第一凸起17和套设在第一凸起17外的环形的第二凸起18，详见图7。更进一步地，如图3所示，凸起设置在提升筋1的顶面19的两排喷淋孔14之间，且设置有多个。多个 凸起沿提升筋1的长度方向排列。
第二实施例：
本实施例公开了一种洗涤设备，其具体结构与第一实施例在的洗涤设备的结构基本相同，不同之处在提升筋的局部具体结构。如图8所示，不同之处在于：在提升筋1的长度方向上(即图8的上下方向)，驱动曲面11向提升筋1的内部凹陷；也即在垂直于提升筋1高度方向的截面上，驱动曲面11向提升筋1内部凹陷。该凹陷形成圆弧状的凹槽111。凹槽111的底部靠近第二端13，当衣物沿驱动曲面11向第二端13滑动时，会落入凹槽111中，以使衣物聚集在滚筒2的内部。
进一步地，提升筋1设置有第一凸起17和第二凸起18，详见图8和图9。本实施例的第一凸起17和第二凸起18，与实施例一的区别为：如图8所示，多个凸起中的第一部分沿提升筋1的长度方向排列，第二部分凸起在靠近第一端12的位置均匀分布在第一部分凸起的两侧。
第三实施例：
本实施例公开了一种洗涤设备，其具体结构与第二实施例在的洗涤设备的结构基本相同，不同之处在提升筋1的局部具体结构。如图10所示，不同之处在于：提升筋1的顶面19上仅设置有一排喷淋孔14。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
