Description

一种洗衣机减震吊杆组件及洗衣机 技术领域
本发明属于洗衣机领域，具体地说，涉及一种洗衣机减震吊杆组件及洗衣机。
背景技术
家用电动洗衣机分为波轮式洗衣机、滚筒洗衣机、搅拌洗衣机。无论对于哪种洗衣机，因为安装有电机，所以震动问题一直都是洗衣机面临的一个重大问题，震动过大、移位、外桶撞箱体等问题在很多型号的洗衣机上都出现过，严重影响和制约了洗衣机的使用性能。
目前的波轮洗衣机采用平衡环加弹簧吊杆的设计，或者在弹簧部位增加阻尼结构；滚筒洗衣机采用配重、阻尼器、平衡环配合的设计。现有的波轮洗衣机包括箱体、外桶部件等，外桶部件与箱体之间是通过四根吊杆减震部件安装在一起的。吊杆减振部位上部有吊杆座，下部有减震套筒，减震套筒内部有弹簧，减震套筒卡在外桶底部的安装部下方，安装部中有悬挂孔，吊杆穿过悬挂孔，上部吊杆座置于箱体四个角加强板的孔中。当在洗涤或者脱水过程中，外桶部件内部的衣物偏移，由于不平衡引起外桶部件震动时，内桶平衡环、吊杆减振部件起到减振调节平衡的作用。但是，在全自动洗衣机脱水启动和脱水运行时，外桶会随着电机启动晃动或摇摆，形成较大的震动和噪音，减震部件的吊杆在外桶摇摆时也会产生晃动，减震套筒和安装部之间也会由于震动而产生冲击、碰撞。
现有结构中，在吊杆上设置环形的减震垫，设在吊杆上，卡在悬吊孔下方，可以起到一定的减小震动、撞击的作用，但减震垫非常容易偏移、与减震套筒的接触面积也小，在较大的震动、撞击力下压力较大，不仅容易损坏，起到的减震、减小冲击的作用有限，并不理想。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗衣机减震吊杆组件及洗衣机，本发明的减震吊杆组件中设置的减震缓冲装置位于安装部和减震套筒之间，包覆减震套筒的上端表面，与减震套筒和安装部的接触面积都大大增加，可以减小安装部与减震套筒之间的碰撞、震动的压力，辅助减小洗衣机的震动，而且不容易损坏；另外，减震缓冲装置 套设在吊杆上的部位还能够产生滑动阻尼，进一步减轻震动。

进一步的方案，所述的减震套筒包括一体成型的托架和套管，托架封堵套管的上端开口；托架包括沿吊杆轴向向上延伸的管状凸缘和由管状凸缘向套管上端开口延伸的过渡结构；所述的减震缓冲装置设有套设部和减震部，套设部套在管状凸缘上，减震部包覆过渡结构的外表面；
优选的，套设部的长度与管状凸缘的长度相同，完全包裹管状凸缘。
进一步的方案，所述的套设部套在管状凸缘的外部，与管状凸缘的外壁保持接触，以产生滑动阻尼。
进一步的方案，套设部的内部设有凸起，与管状凸缘的外壁接触，以增大滑动阻尼；
优选的，所述的凸起为沿吊杆的周向间隔设置的环形凸筋。
进一步的方案，管状凸缘的直径小于套管的直径，管状凸缘的下缘向外延伸至套管上端开口，形成过渡结构，过渡结构的外表面为由吊杆的轴向中心向外倾斜的平面或者曲面；所述的减震部包覆在过渡结构的外部并接触。
进一步的方案，所述的套设部的下缘向外延伸，形成减震部，减震部的内表面与过渡结构的外表面相配合，减震部包覆过渡结构，并与套管的外表面平滑过渡；
优选的，减震部的内表面和过渡结构的外表面为相配合的弧面。
进一步的方案，所述的过渡结构靠近套管的一端设有周向的环形凹台，减震部的边缘与环形凹台相配合，减震缓冲装置套设安装到吊杆上时，减震部的边缘卡在环形凹台内。
进一步的方案，所述的减震部的边缘沿吊杆的轴向延伸，其厚度与环形凹台相配合，并向套管的外表面平滑过渡。
本发明的第二目的是提供一种具有如上所述洗衣机减震吊杆组件的洗衣机。
进一步的方案，包括箱体、设置于箱体内用于盛水的内桶和用于驱动所述内桶转动的驱动装置，还包括用于收集内桶中排出的水的集水装置，所述集水装置位于所述内桶的桶底的下部，所述集水装置的外周设有安装部，减震吊杆组件固定在安装部中并悬挂在洗衣机的箱体上，减震缓冲装置位于安装部和减震套筒之间，并包覆减震套筒的上端表面，以减少震动。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果：
1、本发明的减震吊杆组件中设置的减震缓冲装置位于安装部和减震套筒之间，包覆减震套筒的上端表面，与现有的减震垫相比，增大了与减震套筒和安装部的接触面积，因此，在洗衣机震动，减震吊杆组件上下左右移动时，外桶的安装部与减震套筒之间有柔性材料覆盖的面积增大，两者之间碰撞、震动的产生的压力、震动减小，可以辅助减小洗衣机的震动。
2、本发明的减震缓冲装置与减震套筒和安装部的接触面积都增大，不仅能够更好的减小减震吊杆组件和洗衣机的震动，减震缓冲装置自身受到的压力、冲击也减小，受的力被分散，不容易损坏，延长使用寿命，节约更换成本。
3、另外，本发明的减震缓冲装置套设在吊杆上的部位可以覆盖减震套筒上端的管状凸缘，长度长、接触面积大，套设部与吊杆或者管状凸缘接触，还能够产生沿吊杆轴向的滑动阻尼，可以进一步减轻吊杆、洗衣机的震动。

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。

在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；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。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
实施例一
如图1到图4所示，本发明的提供一种洗衣机减震吊杆组件600，包括吊杆1及吊杆1下端套设的减震套筒2，洗衣机的外桶的底部设有用于吊挂减震套筒2的安装部，减震套筒2置于安装部下方，吊杆1穿过安装部悬挂在洗衣机的箱体上，还包括减震缓冲装置3，所述的减震缓冲装置3套设在吊杆1上，位于安装部和减震套筒2之间，并包覆减震套筒2的上端表面，以减少震动。
洗衣机减震吊杆组件600安装在洗衣机的四个角，洗衣机的外桶底部设有安装部，吊杆1组件的下端安装在洗衣机外桶底部的安装部中，另一端吊挂在相对应的箱体的角上。本发明的外桶可以为普通的外桶，也可以为高度远低于内桶的外桶，也就是配合无孔内桶使用的 外桶或者能够收集内桶的排水的集水装置，只需要在外桶或者集水装置的外周设置安装部即可。
减震套筒2内部设有弹簧组5和用于固定弹簧组5的弹簧座，吊杆1起到连接作用。安装部一般为悬挂座，具有悬挂孔，吊杆1穿过悬挂孔挂到对应位置的箱体上，吊杆1下端的减震套筒2则被卡在悬挂孔下部，这样，在洗衣机震动时，吊杆1组件能够起到减小内桶和洗衣机震动的作用。
本实施例的减震吊杆组件600中设置的减震缓冲装置3位于安装部和减震套筒2之间，包覆减震套筒2的上端表面，与现有的减震垫相比，增大了与减震套筒2和安装部的接触面积，因此，在洗衣机震动，减震吊杆组件600上下左右移动时，外桶的安装部与减震套筒2之间有柔性材料覆盖的面积增大，两者之间碰撞、震动的产生的压力、震动减小，减震效果好，可以辅助减小洗衣机的震动。
另外，减震缓冲装置3与减震套筒2和安装部的接触面积都增大，不仅能够更好的减小减震吊杆组件600和洗衣机的震动，减震缓冲装置3自身受到的压力、冲击也减小，受的力被分散，不容易损坏，延长使用寿命，节约更换成本。
进一步的方案，所述的减震套筒2包括一体成型的托架21和套管22，托架21封堵套管22的上端开口；托架21包括沿吊杆1轴向向上延伸的管状凸缘21-1和由管状凸缘21-1向套管22上端开口延伸的过渡结构21-2；所述的减震缓冲装置3设有套设部31和减震部32，套设部31套在管状凸缘21-1上，减震部32包覆过渡结构21-2的外表面。
减震套筒2的托架21和套管22一体成型，封堵套管22的上端口，套管22的下端口由密封盖6密封，减震套筒2内部形成密闭的腔室。弹簧组5被包裹在减震套筒2中，避免被腐蚀损坏。托架21具有沿着吊杆1轴向向上延伸的管状凸缘21-1，向下沿吊杆1轴向延伸形成可以固定弹簧座的固定座。由于管状凸缘21-1的直径小于套筒的直径，管状凸缘21-1的下端需要向外、向下逐渐延伸直至与套管22的上端开口成一体，也就形成了过渡结构21-2。
本实施例的减震缓冲装置3由柔性材料制成，套设部31套在管状凸缘21-1上，外部又卡在外桶上的安装部下，因此能够起到滑动阻尼的作用，增大吊杆1组件上下运动的摩擦力，减小震动。减震套筒2和安装部一般由塑料材质制成，减震套筒2上下震动时，容易与安装部撞击，减震部32包覆过渡结构21-2的外表面，相当于减震套筒2的整个上端均由柔性材料覆盖，面积大；减震套筒2与安装部之间均有减震缓冲装置3进行缓冲，减小减震套筒2与安装部的撞击、震动，进一步减小洗衣机的震动。
优选的，套设部31的长度与管状凸缘21-1的长度相同，完全包裹管状凸缘21-1，可以增大接触面积，加大滑动阻尼。
进一步的方案，所述的套设部31套在管状凸缘21-1的外部，与管状凸缘21-1的外壁保持接触，以产生滑动阻尼。套设部31与管状凸缘21-1的外周壁不固定，可以紧贴，也可以有一定间隙但保持接触，在发生相对运动时，能够产生滑动阻尼，减小震动。
进一步的方案，套设部31的内部设有凸起，与管状凸缘21-1的外壁接触，以增大滑动阻尼；套设部31为管状，内壁上可以设置向吊杆1凸出的凸起，可以设置多个点状凸起，也可以设置条状、螺旋状等能够增大摩擦力的凸起，可以规则排列，或者不规则排列。
优选的，所述的凸起为沿吊杆1的周向间隔设置的环形凸筋，环形凸筋可以进一步加大滑动阻尼，减小震动。
进一步的方案，管状凸缘21-1的直径小于套管22的直径，管状凸缘21-1的下缘向外延伸至套管22上端开口，形成过渡结构21-2，过渡结构21-2的外表面为由吊杆1的轴向中心向外倾斜的平面或者曲面；所述的减震部32与过渡结构21-2的外表面相配合，包覆在过渡结构21-2的外部并接触。
由于管状凸缘21-1的直径小于套筒的直径，管状凸缘21-1的下端需要向外、向下逐渐延伸直至与套管22的上端开口成一体，过渡结构21-2的外表面由内向外倾斜，可以在减震套筒2的上端卡在安装部中，且发生上下左右的震动时，减小挤压力，避免损坏；减震部32包覆在倾斜设置的过渡结构21-2的外部，可以进一步减小撞击的震动。
进一步的方案，所述的套设部31的下缘向外延伸，形成减震部32，减震部32的内表面与过渡结构21-2的外表面相配合，减震部32包覆过渡结构21-2，并与套管22的外表面平滑过渡；优选的，减震部32的内表面和过渡结构21-2的外表面为相配合的弧面。
减震部32的大小、形状与托架21的过渡结构21-2相配合。过渡结构21-2为由吊杆1的轴向中心向外倾斜的平面或者曲面，相应的，减震部32也为由套设部31下端边缘向外倾斜的平面或者曲面，能够包裹、覆盖过渡结构21-2的外表面，并与之接触，如此，柔性材料的覆盖面积大大增加，而且相互配合，不容易发生偏移，可以在减震套筒2与安装部撞击时，减小受力，减小震动。减震部32与并与套管22的外表面平滑过渡，一是利于美观，二是不会发生挤压减震部32边缘，或者减震套筒2上端边缘无减震部32覆盖的情况，有利于减小震动。减震部32的内表面和过渡结构21-2的外表面为相配合的弧面，可以进一步减小撞击时的受力，避免挤压受损。
进一步的方案，所述的过渡结构21-2靠近套管22的一端设有周向的环形凹台4，减震部32的边缘与环形凹台4相配合，减震缓冲装置3套设安装到吊杆1上时，减震部32的边缘卡在环形凹台4内。
过渡结构21-2的下端设置周向的环形凹台4，减震部32边缘配合设置，插入到环形凹台 4中，可以更好的防止减震缓冲装置3发生位置的偏移，保证可以在震动过程中仍然能够完全包覆减震套筒2的上端，减小减震套筒2与安装部的冲击，进而减小震动。
进一步的方案，所述的减震部32的边缘沿吊杆1的轴向延伸，其厚度与环形凹台4相配合，并向套管22的外表面平滑过渡。
减震部32外表面由中心向外延伸，边缘处改变方向，沿吊杆1的轴向延伸，可以扣在减震套筒2的上端，防止减震缓冲装置3在震动过程中发生位置的偏移，同时，震动部的边缘向套管22的外表面平滑过渡，可以保护外缘，避免边角被震动时的撞击损坏。
实施例二
如图5所示，本实施例提供一种具有如实施例一所述的洗衣机减震吊杆组件600的洗衣机。本实施例的洗衣机包括箱体、设置于箱体内用于盛水的内桶和用于驱动所述内桶转动的驱动装置，还包括用于收集内桶中排出的水的集水装置，所述集水装置位于所述内桶的桶底的下部，所述集水装置的外周设有安装部，减震吊杆组件600固定在安装部中并悬挂在洗衣机的箱体上，减震缓冲装置3位于安装部和减震套筒2之间，并包覆减震套筒2的上端表面，以减少震动。
通过设置集水装置，一方面当水从内桶200排出时，通过集水装置收集内桶中脱水时排出的水，防止水的溢出，另一方面，由于集水装置整体位于内桶200以下，使集水装置不具有位于内桶200的侧壁和箱体100之间的部分结构，对内桶200的扩容不具有限制作用，为内桶200的扩容提供充裕的空间。
所述集水装置包括具有上开口的集水腔400，所述集水腔400的侧壁上端低于所述内桶200的桶底，所述内桶200与集水腔400的上开口连通。
通过设置集水腔400，实现对内桶200内排出的水进行阻挡，由于集水腔400的侧壁上端低于所述内桶200的桶底，使集水腔400整体位于洗衣桶206的桶底以下，使集水腔400的侧壁不具有位于内桶200和箱体100之间的结构，不用在内桶200和集水装置之间设置一定的安全距离，防止内桶200碰撞到集水装置造成损坏，同时也不用在集水装置和箱体100之间再设置安全距离，因此仅设计内桶200与箱体100之间的安全距离即可，可以大大增加内桶200桶径，更好的实现内桶200的扩容。
所述集水腔400的侧壁与所述内桶200的桶底的外壁之间间隔一定间距。
通过使集水腔400的侧壁上端低于内桶200的桶底，并且使集水腔400的侧壁与内桶200的桶底的外壁之间间隔一定间距，防止洗衣桶206震动时与集水腔400的侧壁进行碰撞，从 而提高集水腔400的使用寿命。
所述集水腔400上设有用于将集水装置内的水排出的排水管401，所述排水管401延伸至洗衣机外。
所述内桶200包括在甩干时用于排水的第一排水口201和与第一排水口201连通的第一排水管路202，所述第一排水管路202的出水口203与集水装置连通。通过第一排水口201连通的第一排水管路202将洗衣桶206内的水排入集水装置，进而通过排水管401将水排出。
实施例三
如图5和图6所示，本实施例为对实施例二的进一步限定，本实施例中，所述集水装置包括安装板500和设置在安装板500上的挡水筋501，所述安装板500与挡水筋501围合形成集水腔400。通过设置安装板500和挡水筋501，并使二者围合形成集水腔400，该结构简单，便于加工成型。
集水腔400位于安装板500的中部，使挡水装置的重心更容易与中心重合，减少偏移。
所述挡水筋501为环状，所述挡水筋501与安装板500围合形成环状集水腔400。
进一步地，所述挡水筋501倾斜设置，通过将挡水筋501设置成倾斜状，能够最大限度的增加挡水量，更便于使用；
进一步地，所述挡水筋501自上而下向集水腔400的中轴线方向逐渐收缩，使上开口口径更大，更加便于收集。
进一步地，所述内桶200的底部外壁为弧面，所述挡水筋501与内桶200的弧面间隔一定间距。
进一步地，所述内桶200在水平方向的投影覆盖所述集水腔400在水平方向的投影。通过将内桶200在水平方向的投影覆盖所述集水腔400在水平方向的投影，增加集水腔400对箱体100之间的间隔，防止集水腔400对箱体100的碰撞，减少集水腔400的损坏；同时集水腔400小，更便于箱体100底部其他装置的安装。
所述内桶200在水平方向的投影也可以小于所述集水腔400在水平方向的投影，能够收集的水更多。
进一步地，安装板500上设有排水管401，排水管401的一端与集水腔400连通，另一端通至洗衣机外或者与洗衣机的总的排水管路连通，将水排出。通过在集水腔400内设置用 于将集水装置内的水排出的排水管401，当水排入集水腔400后，通过排水管401将集水腔400内的水排出，防止集水腔400内水过多而溢出。
进一步地，内桶200桶壁上设有第一排水口201和第一排水口201连通的第一排水管路202，所述第一排水管路202的出水口203设置在集水腔400的上开口的上方。第一排水口201和第一排水管路202均为多个，每个第一排水口201分别与相对应的第一排水管路202，也可以多个第一排水口201对应一个第一排水管路202，当洗衣机执行甩干程序时，由于洗衣桶206的离心作用而被甩出的水通过第一排水口201进入第一排水管路202，并通过第一排水管路202的出水口203排入集水腔400，阻挡水的四处溢流。
所述第一排水管路202的出水口203设置在集水腔400的上开口的上方。通过将出水口203与集水装置连通，甩干时水经第一排水口201进入第一排水管路202再经出水口203排出进入集水腔400，阻挡水溢出；出水口203设置在挡水筋501围城的集水腔400的上开口的上方，从出水口203排出的水直接落入集水腔400，该结构更加简单，无需增加其他附加部件，集水效果更好。
进一步地，所述内桶200还包括在脱水和/或甩干时用于将内桶200内的水排入集水腔400的第二排水口204，第二排水口204与集水腔400之间设有封堵装置205，所述封堵装置205在脱水和/或甩干时将第二排水口204打开，内桶200内的大量的水通过第二排水口204排出，在洗衣时将所述第二排水口204封堵，将水保留在内桶200中进行洗衣。
进一步地，所述第二排水口204设置所述集水腔400的上开口的上方，所述封堵装置205设置在第二排水口204的下部。
通过设置第二排水口204，在脱水和/或甩干时，封堵装置205打开第二排水口204，将内桶200中的水直接排入集水装置，挡水筋501阻挡水防止水溢出，并通过排水管401将水排出洗衣机；当洗衣时，封堵装置205将第二排水口204封堵，使内桶200中的水存留于内桶200中进行洗衣。
洗衣机为波轮洗衣机。
所封堵装置205包括阀塞205-1和设置在阀塞205-1下的电磁装置205-2，电磁装置205-2与洗衣机的控制装置电连接，当洗衣机处于洗衣状态时，阀塞205-1将第二排水口204封堵防止内桶200中的水排出，当洗衣机处于排水或脱水状态时，所述电磁装置205-2控制阀塞205-1向下运动，使第二排水口204开启，将水排入集水装置中。
安装板500上设有定位装置，内桶200底壁上设有与定位装置向匹配的配合部，配合部可以为定位凹槽，定位装置在脱水和/或甩干时，定位装置与配合部脱离，内桶200随输出轴303转动，当洗衣机处于洗衣状态时，定位装置与配合部配合，将内桶200卡在安装板500上，阀塞205-1正好与第二排水口204相对，将第二排水口204封堵防止内桶200中的水排出，输出轴带动洗衣机内的波轮转动。
进一步地，所述安装板500设置在内桶200与驱动装置300之间，所述安装板500的下部与驱动装置300的外壳固定连接。通过将安装板500设置在内桶200与驱动装置300之间，一方面内桶200中的水能够依靠自重下降，自动流入集水装置，另一方面安装板500设置在驱动装置300的上部，将水与驱动装置300隔离，防止水对驱动装置300造成的损坏。
驱动装置300包括电机301，电机301上方设有减速离合装置302，安装板500的下部与减速离合器或与电机301的外壳固定连接。
安装板500与驱动装置300的连接方式还可以为：所述安装板500与驱动装置300的输出轴303之间通过轴承连接。
进一步地，减速离合器的输出轴303穿过所述安装板500与内桶200连接，驱动内桶200的转动，安装板500与驱动装置300的输出轴303之间通过轴承连接。
实施例四
如图5-6所示，一种悬吊式扩容洗衣机,包括箱体100、设置于箱体100内的洗衣桶206和驱动装置300，所述驱动装置300的输出轴303与洗衣桶206连接用于驱动洗衣桶206转动，还包括减震吊杆组件600和设置在洗衣桶206下部的安装件700，所述驱动装置300安装在所述安装件700上，所述减震吊杆组件600的一端与箱体100连接，另一端与安装件700连接。减震套筒2卡在安装部下方，减震缓冲装置3为减震套，包覆在减震套筒2的上端，并位于减震套筒2和安装部之间。
通过在洗衣桶206下设置安装件700，将减震吊杆组件600安装在安装件700上，由于安装件700较洗衣桶206位置更靠下，降低了安装部701的纵向的高度，使安装后的减震吊杆组件600与箱体侧壁之间的倾斜角度θ减小，进而使减震吊杆组件600的占用空间减小，当将该结构悬吊于洗衣桶206与箱体100之间时，便能够实现在不增加箱体100体积的前提下增加洗衣桶206的直径，实现扩容的目的。
洗衣桶206可以为仅具有内桶200的洗衣桶206，内桶200用于盛水并进行洗衣，洗衣 桶206也可以为具有内桶200和外桶的洗衣桶206。
进一步地，所述安装件700包括用于与减震吊杆组件600装配的安装部701，所述安装部701不高于所述洗衣桶206的桶底。
安装部701不高于洗衣桶206的桶底，使其不占用洗衣桶206与箱体100之间的空间，能够增加洗衣桶206的直径，实现扩容。
进一步地，所述安装部701位于所述洗衣桶206的桶底以下，当减震吊杆组件600与安装部701装配后，由于安装部701设置的低于洗衣桶206的桶底，使减震吊杆组件600与箱体100之间形成的倾斜角的角度减小，即，使减震吊杆组件600与箱体100的内壁更加贴合，为洗衣桶206预留了更充裕的空间，因此可以通过增加洗衣桶206的直径实现扩容的目的。
进一步地，所述安装部701在水平方向的投影位于所述洗衣桶206在水平方向的投影的外围。
由于安装部701设置在洗衣桶206的桶底以下，不占用洗衣桶206与箱体100之间的空间，安装部701不会与洗衣桶206产生碰撞，在这个前提下，将安装部701在水平方向上延伸至洗衣桶206桶壁以外，使安装部701在水平方向的投影位于所述洗衣桶206在水平方向的投影的外围，进一步的减少了减震吊杆组件600的安装空间，进而增加了洗衣桶206的安装空间，实现洗衣桶206的扩容。
进一步地，所述输出轴303穿过安装件700与洗衣桶206连接用于驱动洗衣桶206转动，所述安装件700与输出轴303通过轴承连接。
其中，安装件700也可以与驱动装置300的外壳固定连接，将安装件700、驱动装置300和洗衣桶206成为一相对独立的整体；安装件700也可以与驱动装置300的外壳固定连接的同时与输出轴303通过轴承连接，将安装件700、驱动装置300和洗衣桶206成为一相对独立的整体。
所述安装件700与输出轴303通过轴承连接和/或与驱动装置300的外壳固定连接，使安装件700、驱动装置300和洗衣桶206成为一相对独立的整体，通过减震件减少安装件700的震动进而实现减少洗衣桶206、驱动装置300的震动，进而实现良好的减震效果。
所述安装件700为中心对称结构，所述减震吊杆组件600为多个，多个所述的减震吊杆组件600均匀分布在安装件700的四周。
通过将安装板500设置为中心对称结构，降低安装板500、洗衣桶206和电机301整体 重心偏离的可能，实现更好的减震效果；将安装板500设置为圆形，一方面便于安装驱动装置300，另一方面使结构更加平稳
实施例五
如图5-6所示，本实施为对实施例四的进一步限定，本实施例中安装件700为平板状的圆形安装板500，安装板500的直径大于所述洗衣桶206的直径，所述安装板500设置在洗衣桶206的下方，所述减震吊杆组件600的下端与安装板500的边缘装配，使减震吊杆组件600与安装板500相连的连接部位于洗衣桶206的下部并位于洗衣桶206的周向以外，即，安装部701位于洗衣桶206桶底的斜下方，减少减震吊杆组件600的悬吊空间，进而在不增加箱体100体积的前提下，为洗衣桶206预留的空间增加。
所述驱动装置300装配于在安装板500的下部，所述驱动装置300的输出轴303穿过所述安装板500并与所述安装板500通过轴承连接。
减震吊杆组件600为四个，均匀分布在圆形安装板500的四周。
所述减震件包括吊杆1和用于产生阻尼作用力的减震套筒2，所述吊杆1的一端与箱体100的上部固定，另一端穿过所述的安装部701与减震套筒2连接。
减震套筒2位于安装板500的下部，使减震套筒2在水平方向上不占用箱体100和洗衣桶206之间的空间，进一步减少减震套筒2对洗衣桶206扩容造成的阻碍。
减震件与箱体100和安装板500的安装方式还可以是：所述箱体100上部设有安装座，所述吊杆1的一端与安装件700连接，另一端穿过安装座与减震套筒2连接。
安装件700也可以为十字形安装板500的，减震吊杆组件600分别与十字形安装板500的各分支的边缘连接，减震吊杆组件600与十字形安装板500连接的安装部701低于洗衣桶206的桶底，使其不会在洗衣桶206和箱体100之间占用空间同时通过安装部701降低，减小减震吊杆组件600的安装空间，实现洗衣桶206的扩容。
安装板500可以是平板，也可以是中间高边缘低的结构，如，包括环状边缘板、圆形中心板和用于连接边缘板和中心版的连接竖板，剖面形成“Ω”形。
其中，安装板500也可以与驱动装置300的机壳固定连接，当然安装板500也可以同时与机壳和输出轴303通过轴承连接。
实施例六
如图5-6所示，在实施例四和实施例五的基础上，本实施例中，减震装置包括电机301，电机上设有减速离合器，减速离合器的输出轴303与洗衣桶206连接驱动洗衣桶206转动。所述减震装置还包括第一减震件703，所述第一减震件703一端与安装件700活动连接，另一端与箱体100底部活动连接。第一减震件703对安装件700施加一个向下的拉力，使得安装件700同时受到第一减震件703向下的拉力和减震吊杆组件600向上的拉力，通过二者的合力作用实现更好的减震效果。
安装件700为圆形平板状的安装板500，减震吊杆组件600自上部与安装板500连接，第一减震件703自下部与安装板500连接，实现减震吊杆组件600与第一减震件703同时作用于安装板500，对安装板500起到减震作用进而实现对洗衣桶206和电机301的减震效果。
安装件700的另一种方案，安装件700包括与减震吊杆组件600连接的安装大板700-1和与第一减震件703连接的安装小板700-2，安装大板700-1与安装小板700-2之间通过加强筋连接，以增强安装件的强度。加强筋间隔设置，增强效果更好。由于洗衣机箱体100的底壁需要设置加强结构和安装其他部件，一般将安装大板700-1的直径设计的大于安装小板700-2的直径，为其他部件的安装提供空间。分开设置更加节约安装件700一下的空间，更方便使用。
进一步地，所述第一减震件703一端与安装件700铰接，另一端与箱体100底部铰接。
更近一步地，所述第一减震件703为减震器。
进一步地，洗衣机还包括设置在驱动装置300上的第二减震件704，所述第二减震件704的一端与驱动装置300固定连接，另一端固定连接在箱体100的底壁上。
通过设置第二减震件704，使其对驱动装置300施加一个向下的拉力或者向上的弹力，结合第一减震件703和减震吊杆组件600，使安装板500、驱动装置300和洗衣桶206形成的整体在单个部件的共同作用下达到更好的减震效果。
进一步地，所述第二减震件704的一端与电机301的定子固定连接，另一端固定连接在箱体100的底壁上。
更进一步地，第二减震装置为减震弹簧。
更进一步地，洗衣机上还设有集水装置，用于阻挡从内桶200中排出的水溢出，所述集水装置整体位于所述内桶200桶底的下部。集水装置包括具有上开口的集水腔400，所述集水腔400的侧壁上端低于所述内桶200的桶底，所述内桶200与集水腔400的上开口连通。
具体来说，安装板500上设置挡水筋501，所述安装板500与挡水筋501围合形成集水腔400。通过设置安装板500和挡水筋501，并使二者围合形成集水腔400，该结构简单，便于加工成型。
集水腔400位于安装板500的中部，使挡水装置的重心更容易与中心重合，减少偏移。
所述挡水筋501为环状，所述挡水筋501与安装板500围合形成环状集水腔400。
进一步地，所述挡水筋501倾斜设置，通过将挡水筋501设置成倾斜状，能够最大限度的增加挡水量，更便于使用；
进一步地，所述挡水筋501自上而下向集水腔400的中轴线方向逐渐收缩，使上开口口径更大，更加便于收集。
进一步地，所述内桶200的底部外壁为弧面，所述挡水筋501与内桶200的弧面间隔一定间距。
进一步地，所述内桶200在水平方向的投影覆盖所述集水腔400在水平方向的投影。通过将内桶200在水平方向的投影覆盖所述集水腔400在水平方向的投影，增加集水腔400对箱体100之间的间隔，防止集水腔400对箱体100的碰撞，减少集水腔400的损坏；同时集水腔400小，更便于箱体100底部其他装置的安装。
所述内桶200在水平方向的投影也可以小于所述集水腔400在水平方向的投影，能够收集的水更多。
进一步地，安装板500上设有排水管401，排水管401的一端与集水腔400连通，另一端通至洗衣机外或者与洗衣机的总的排水管路连通，将水排出。通过在集水腔400内设置用于将集水装置内的水排出的排水管401，当水排入集水腔400后，通过排水管401将集水腔400内的水排出，防止集水腔400内水过多而溢出。
进一步地，内桶200桶壁上设有第一排水口201和第一排水口201连通的第一排水管路202，所述第一排水管路202的出水口203设置在集水腔400的上开口的上方。第一排水口201和第一排水管路202均为多个，每个第一排水口201分别与相对应的第一排水管路202，也可以多个第一排水口201对应一个第一排水管路202，当洗衣机执行甩干程序时，由于洗衣桶206的离心作用而被甩出的水通过第一排水口201进入第一排水管路202，并通过第一排水管路202的出水口203排入集水腔400，阻挡水的四处溢流。
所述第一排水管路202的出水口203设置在集水腔400的上开口的上方。通过将出水口 203与集水装置连通，甩干时水经第一排水口201进入第一排水管路202再经出水口203排出进入集水腔400，阻挡水溢出；出水口203设置在挡水筋501围城的集水腔400的上开口的上方，从出水口203排出的水直接落入集水腔400，该结构更加简单，无需增加其他附加部件，集水效果更好。
进一步地，所述内桶200还包括在脱水和/或甩干时用于将内桶200内的水排入集水腔400的第二排水口204，第二排水口204与集水腔400之间设有封堵装置205，所述封堵装置205在脱水和/或甩干时将第二排水口204打开，内桶200内的大量的水通过第二排水口204排出，在洗衣时将所述第二排水口204封堵，将水保留在内桶200中进行洗衣。
进一步地，所述第二排水口204设置所述集水腔400的上开口的上方，所述封堵装置205设置在第二排水口204的下部。
通过设置第二排水口204，在脱水和/或甩干时，封堵装置205打开第二排水口204，将内桶200中的水直接排入集水装置，挡水筋501阻挡水防止水溢出，并通过排水管401将水排出洗衣机；当洗衣时，封堵装置205将第二排水口204封堵，使内桶200中的水存留于内桶200中进行洗衣。
洗衣机为波轮洗衣机。
所封堵装置205包括阀塞205-1和设置在阀塞205-1下的电磁装置205-2，电磁装置205-2与洗衣机的控制装置电连接，当洗衣机处于洗衣状态时，阀塞205-1将第二排水口204封堵防止内桶200中的水排出，当洗衣机处于排水或脱水状态时，所述电磁装置205-2控制阀塞205-1向下运动，使第二排水口204开启，将水排入集水装置中。
安装板500上设有定位装置，内桶200底壁上设有与定位装置向匹配的配合部，配合部可以为定位凹槽，定位装置在脱水和/或甩干时，定位装置与配合部脱离，内桶200随输出轴303转动，当洗衣机处于洗衣状态时，定位装置与配合部配合，将内桶200卡在安装板500上，阀塞205-1正好与第二排水口204相对，将第二排水口204封堵防止内桶200中的水排出，输出轴带动洗衣机内的波轮转动。
进一步地，所述安装板500设置在内桶200与驱动装置300之间，所述安装板500的下部与驱动装置300的外壳固定连接。通过将安装板500设置在内桶200与驱动装置300之间，一方面内桶200中的水能够依靠自重下降，自动流入集水装置，另一方面安装板500设置在驱动装置300的上部，将水与驱动装置300隔离，防止水对驱动装置300造成的损坏。
驱动装置300包括电机301，电机301上方设有减速离合装置302，安装板500的下部与减速离合器或与电机301的外壳固定连接。
