需要说明的是，这些附图和文字描述并不旨在以任何方式限制本发明的构思范围，而是通过参考特定实施例为本领域技术人员说明本发明的概念。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一
如图1至图6所示，本发明提供一种洗衣机波轮，包括波轮和波轮护罩101，所述波轮护罩包括密封部1和卡接部2，所述密封部1与波轮下表面密封连接，形成密闭空间，所述卡接部2与波轮下表面卡接，限制水流进入进行密封。
本发明的洗衣机波轮下表面安装有波轮罩，波轮罩具有密封部和卡接部，可以同时利用卡接和密封连接两种方式固定在波轮下部，形成防止水流进入的密闭空间。水流无法进入也就避免了污垢和细菌在波轮下表面的堆积，进而可以波轮底部的整洁，避免衣物的二次污染。
密封部和卡接部可以一体化成型，也可以密封连接；所述的卡接部可以直接通过插接或卡接的方式连接在波轮下表面，利用洗涤时水的挤压形成防水空间，密封部可以通过熔敷焊接的方式与波轮下表面密封连接，形成密闭空间，可以采用超声波焊接、激光焊接等。
波轮护罩的密封部和卡接部均与波轮下表面的结构相配合设置，如与波轮下表面的加强筋相配合。这样，卡接部使波轮护罩在安装时易于定位，密封部将波轮护罩与波轮固定连接，两者配合，形成波轮下表面的防水空间，防止污垢堆积的效果好，安装也方便。
波轮护罩与波轮中心连接，波轮护罩外周与波轮外周之间波轮的基体上设置泄水孔8，用于水流流出，而在波轮被波轮护罩覆盖的区域则不设置泄水孔，使波轮护罩和波轮之间的 区域为密闭空间或者防止水流进入的防水空间，进而防止污垢和细菌在波轮底部堆积。
实施例二
如图1-5所示，本实施例为实施例一的进一步限定，所述卡接部包括多个间隔设置的卡爪3，所述波轮的下表面设置有与卡爪配合卡接的加强筋。
波轮的下表面设置有加强筋，原本波轮的底部被加强筋分隔成多个小区域，水流容易将洗涤过程的污垢带进来，堆积在加强筋底部，但不容易将污垢带出。波轮护罩的卡接部设有多个卡爪，卡爪与加强筋配合卡接，在洗涤时，由于水的挤压作用，水流无法进入卡接处的加强筋根部，实现防水，进而实现防污垢。
进一步的方案，所述波轮的下表面设置环形加强筋6和径向加强筋7，所述环形加强筋6和径向加强筋7相交形成凹槽9，所述卡爪凸出于密封部平面设置，卡爪3插入凹槽9中，径向加强筋7卡在相邻卡爪之间。
卡爪凸出于密封部平面设置，插入加强筋形成的凹槽中，径向加强筋恰好卡在相邻卡爪的之间。卡爪可以设置为内部中空，上部开放，当卡爪的外壁与凹槽的内壁的间隙小于一定距离时，即使卡接时卡爪外壁与凹槽的内壁未接触，在洗涤时，由于水的挤压，使卡爪内压强增大，水流无法进入。或者卡爪可以采用弹性材料设置。
进一步地限定，所述卡爪的至少一个外壁与加强筋的外壁之间的距离小于0.5mm。经过多次重复试验检测，当卡爪的外壁与加强筋的外壁之间的距离小于0.5mm时，可以确保水流无法进入卡爪，即无法进入波轮的下表面的加强筋形成的凹槽，完全实现防水，进而实现防垢。
实施例三
如图1-5所示，本实施例为实施例一和实施例二的进一步限定，所述密封部的上表面设有与波轮下表面的环形加强筋相配合的环形连接筋4，在环形连接筋4围合的范围内沿其径向设置有径向连接筋5，所述密封部的最内圈环形连接筋和最外圈环形连接筋分别与波轮下表面相应的环形加强筋6熔敷连接，形成密闭空间。
密封部为水平的盘面，盘面上设有环形连接筋，与波轮下表面的环形加强筋相配合。密封部可以为环形盘面，密封部的最内圈环形连接筋和最外圈环形筋分别与波轮下表面相应的环形加强筋熔敷连接，形成密闭空间。一方面将波轮护罩与波轮固定连接，另一方面将波轮下表面的熔敷的环形加强筋围合的区域覆盖，并形成密闭空间，防水防垢。
实施例四
波轮护罩上，卡接部和连接部可以有多种组合连接方式，只要能够使波轮护罩覆盖波轮下表面的区域形成防止水流进入的密闭空间即可。例如，卡接部设置在波轮护罩中央，与波轮中心的加强筋配合卡接，密封部的环形盘面环绕在卡接部外周，与波轮较外圈的环形筋密封连接；或者密封部设置在波轮护罩中央，卡接部的卡爪环绕密封部外周。
如图1-5所示，本实施例提供的洗衣机波轮，所述卡爪3设置在波轮护罩的上表面中央，卡爪3的外围设置密封部1，所述卡爪3和密封部1密封连接。
波轮的下表面中心位置的环形加强筋和径向加强筋高度较高，相交形成的凹槽较深，采用熔敷密闭时不易操作，将卡爪设置在波轮护罩中央，与波轮下表面中心较深的凹槽相配合，易于安装操作，防水效果也较好。
所述波轮的中心设有用于安装波轮转轴的轴孔10，所述的卡爪3沿着波轮护罩的上表面中央周向设置形成圆环形结构，所述圆环形结构的内圆周与轴孔10外径相配合，所述圆环形结构的外圆周与环形的密封部1密封连接。
卡爪沿着波轮护罩的上表面中央周向设置形成圆环形结构，圆环形结构的内圆周与轴孔外径相配合，用于安装穿过波轮护罩和波轮的波轮转轴。密封部为环形，其内圆周与圆环形结构的外圆周密封连接，同时密封部的内圆周和外圆周均设有环形连接筋，分别与波轮下表面相匹配的环形加强筋熔敷，形成固定的密闭空间。
另外一种方案，所述波轮的中心设有用于安装波轮转轴的轴孔10，所述波轮护罩的上表面中央设置环形的密封部1，所述环形的密封部1的内圆周与轴孔外径相配合，所述密封部1的外圆周环绕设置多个卡爪3。
密封部设置在波轮护罩中央，卡爪环绕密封部的外圆周设置时，也可以实现卡接和密封连接结合的方式，形成防水空间，且将波轮护罩与波轮固定连接。
实施例五
如图6所示，本实施例的波轮为塑料波轮102，所述塑料波轮下表面连接波轮护罩101，所述塑料波轮上表面设置有钣金波轮103，所述钣金波轮上表面设置有转轮104。
本发明在不改变塑料波轮的结构的前提下，增加波轮护罩，并可结合卡接和熔敷密封连接将波轮护罩固定在塑料波轮的下表面，形成防止水流进入的密闭空间，易于安装，也避免污垢在波轮下表面堆积。
钣金波轮的形状与塑料波轮相匹配，安装并覆盖在塑料波轮的上表面，表面光滑，不易磨损衣物，增加波轮的使用寿命，也增强波轮的美观性。
实施例六
本实施例提供一种洗衣机，安装有本发明所述的波轮。
本发明的洗衣机，洗衣机的塑料波轮102下表面安装有波轮护罩101，波轮护罩的卡接部的卡爪3沿着波轮护罩的上表面中央周向设置形成圆环形结构，所述圆环形结构的内圆周与轴孔10外径相配合，所述圆环形结构的外圆周与环形的密封部1密封连接。
密封部的内圆周和外圆周均设有环形连接筋，分别与波轮下表面相匹配的环形加强筋熔敷，形成固定的密闭空间。卡接部的卡爪凸出于密封部平面设置，卡爪插入波轮下表面中心的环形加强筋和径向加强筋相交形成的凹槽中，径向加强筋卡在相邻卡爪之间，形成卡接的防水空间。
如此，波轮下表面被波轮护罩覆盖的区域形成防止水流进入的空间，避免污垢和细菌在波轮下表面的加强筋处堆积，保持波轮底部的整洁，避免衣物的二次污染。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
