实施例一
如图1-3所示，本实施例提供一种洗衣机，包括洗衣机壳体1、设置于洗衣机壳体1内的内桶2和外桶3，还包括悬吊减震件4和支撑减震件5，所述悬吊减震件4和支撑减震件5均设置在洗衣机壳体1和外桶3之间，并分别与洗衣机壳体1和外桶3相连接，所述悬吊减震件4将外桶3悬吊于洗衣机壳体1内，所述支撑减震件5支撑所述外桶3，支撑减震件5和悬吊减震件4共同作用以减少内桶2和外桶3的晃动。
本实施例的洗衣机通过洗衣机壳体1和外桶3之间分别设置悬吊减震件4和支撑减震件5，两者采用不同的减震方式，可以相互配合，共同作用减少内桶2和外桶3的晃动，大大减 小洗衣过程中桶总成(包括内桶2和外桶3)撞击洗衣机壳体1的几率。如此，不仅增强了外桶3和内桶2的抗偏移能力，还可以减小低速过共振点时的振动作用，减小洗衣机噪声，增强洗衣过程的安全性，提升用户体验。
所述悬吊减震件4的一端与洗衣机壳体1的上部连接，另一端与外桶3的侧壁连接，所述支撑减震件5的一端与洗衣机壳体1的下部铰接连接，另一端与外桶3的底部或者外周侧壁铰接连接，支撑减震件5和悬吊减震件4错开设置。
洗衣机外桶3的侧壁上设置用于安装悬吊减震件4的安装部9，安装部9向外突出。悬吊减震件4包括吊杆41和用于产生阻尼作用力的减震套筒42，吊杆41的一端与减振单元固定连接或者一体成型。减震套筒42位于安装部9的下方，吊杆41穿过外桶3侧壁的安装部9，悬挂在洗衣机壳体1的上部。
安装完毕后，减震套筒42卡在安装部9中，在洗衣机震动时，吊杆41和减震套筒42随着震动，减震套筒42中的减震件发生形变，且相应的会产生回复形变需要的反向的作用力，抵消震动的作用力，从而减小洗衣机的震动。悬吊减震件4能够大大减小洗衣机在竖直方向上的震动，避免洗衣机与地面上下相对运动，发出大的噪音。
悬吊减震件4具有减震套筒42的一端与外桶3的侧壁连接，可以使吊杆41能够不受阻碍的与洗衣机壳体1的悬挂连接，可以避免外桶3与吊杆41发生碰撞。
支撑减震件5设置在外桶3的下方，两端分别与洗衣机壳体1和外桶3的底部或者外周侧壁铰接连接，因此可以产生相对转动。支撑减震件5优选减震阻尼器，在洗衣机发生震动时，支撑减震件5能够对震动的作用力产生反方向的阻尼作用力，减小洗衣机的震动。
具体来说，减震阻尼器包括套筒和伸入套筒的活塞杆，套筒内充满液体或气体，活塞杆上伸出套筒的一端与外桶底31侧壁312连接，套筒的底部与洗衣机壳体1的内壁连接。
所述减震阻尼器为充气式减震阻尼器或液压式减震阻尼器。
本方案的悬吊减震件4设置在外桶3的侧部，支撑减震件5设置在外桶3的底部或者外周侧壁下方，因此两种减震件也上下设置。也就是说洗衣机采取上部吊杆41下部阻尼的方式，共同起到减震作用，减震效果更佳。
悬吊减震件4和支撑减震件5在竖直方向上可以位于同一平面上，也可以不在同一平面上，优选的，两者在竖直方向的不同平面上设置，也就是说两者上下交错设置。如此，可以更均匀、稳定的起到减震的作用。
进一步的方案，所述悬吊减震件4设有多个，沿所述外桶3的周向均匀分布，所述支撑 减震件5也设有多个，绕外桶3的中轴线均匀分布；所述悬吊减震件4在水平方向的投影与支撑减震件5在水平方向的投影间隔分布。
悬吊减震件4和支撑减震件5均可以设置多个，分别在外桶3的外周、外桶3的底部或者外周侧壁均匀分布，如此设置可以分散受力，并各减震件的受力均匀，不仅能够大大增强外桶3和内桶2的抗偏能力，也能够避免单个减震件受力过大发生损害，保证达到良好的减震效果。
此时，悬吊减震件4在水平方向的投影与支撑减震件5在水平方向的投影间隔分布，也就是说相邻的两个悬吊减震件4之间的下方设置有支撑减震件5，两个相邻支撑减震件5的上方设置有悬吊减震件4，如此，各减震件配合能够在更多的方向上起到减震作用，防止外桶3和内桶2偏移的效果更好，进一步减小外桶3撞击洗衣机壳体1的概率。
优选地，悬吊减震件4在水平方向的投影与其相邻两个悬吊减震件4在水平方向的投影形成的夹角相等。
如此，不仅各个悬吊减震件4之间的距离相同，各个支撑减震件5之间的距离相同，每一个支撑减震件5到相邻的悬吊减震件4之间的距离均相同，可以将洗衣机震动的作用力完全均匀的分散到各个减震件上，大大减小外桶3偏移概率的同时，各个减震件还能够快速吸收震动，保持洗衣机的平稳、减小噪声。
进一步的方案，所述悬吊减震件4和支撑减震件5均成对设置，每一对悬吊减震件4和支撑减震件5分别以外桶3的中轴线为中心对称设置，如此设置可以避免作用力分散不均匀，洗衣机外桶3向一侧偏移，有利于增强桶总成的抗偏移能力。
具体的方案，悬吊减震件4和支撑减震件5各设置一对，对称设置，两个悬吊减震件4在竖直方向上所形成的平面与两个支撑减震件5所形成的平面互相垂直，；四个减震件在多个方向上分散震动的作用力，达到良好的减震效果。当然，两个悬吊减震件4和两个支撑减震件5在竖直方向上位于同一平面中，也可以起到减震作用。
优选地，所述悬吊减震件4为两对，支撑减震件5为两对，两对悬吊减震件4所形成的平面互相垂直，两对支撑减震件5所形成的平面互相垂直。
悬吊减震件4外桶3的外侧设置四个，均匀分布在外桶3的四周；支撑减震件5在外桶3的底部或者外周侧壁设置四个，也均匀分布在四周，如此，两对支撑减震件5所形成的平面能够互相垂直，两对悬吊减震件4所形成的平面互相垂直，增强桶总成的抗偏能力的效果好，减小低速过共振点时的振动作用。
进一步的方案，所述悬吊减震件4和支撑减震件5均倾斜设置于洗衣机壳体1和外桶3之间；如此稳固定更好，减震作用的余量更大，不仅可以减小在竖直方向的上的震动，在其它的方向上也能起到一定的减震作用。
优选地，所述悬吊减震件4自下向上，由内向外倾斜，所述支撑减震件5自下而上，由外向内倾斜。
洗衣机震动时，外桶3向外偏移，两种减震件与洗衣机壳体1连接的一端到洗衣机中心轴线的距离均大于减震件与外桶3连接的一端到洗衣机中心轴线的距离，可以更大程度的随着洗衣机震动产生形变或者阻尼力，减震效果更佳。由于外桶3上部的震动大于下部，悬吊减震件4自下向上，由内向外倾斜，上端与外桶3的距离大，避免外桶3撞击吊杆41，也能够更稳定的悬挂在洗衣机壳体1上部。
实施例二
如图1-3所示，本实施例为实施例一的进一步的限定，本实施例的外桶3包括外桶底31和外桶体32，外桶体32与外桶底31的上部连接；所述悬吊减震件4的一端与外桶体32的侧壁连接，另一端与洗衣机壳体1连接；所述支撑减震件5的一端与外桶底31的底部或者外周侧壁连接，另一端与洗衣机壳体1连接。
外桶体32的侧壁基本竖直设置，侧壁上设置与悬吊减震件4的减振单元相配合的向外突出的安装部9，悬吊减震件4装配在安装部9中，吊杆41不会受到阻碍，支撑减震件5与外桶底31的底部或者外周侧壁连接，两者能够共同作用于外桶3，起到共同减震的作用。
所述外桶底31的下部还设置有安装板6，所述安装板6与外桶底31固定连接，所述支撑减震件5的一端与安装板6固定，另一端与洗衣机壳体1连接。
安装板6设置在外桶底31的下部，可以用于安装电机10等驱动装置，对外桶3、内桶2也能够起到支撑作用，增强桶总成的抗偏能力。支撑减震件5与安装板6固定，不仅更够减小外桶3、内桶2的震动，也能够减小安装板6、驱动装置等的震动，可以进一步增强减震效果。
优选地，外桶底31的底部与安装板6通过加强筋7连接，可以实现固定连接，又能够很好的支撑内桶2和外桶3，配合电机10和外桶底31之间的距离，避免电机10的重心过高，容易发生晃动。
加强筋7在外桶底31的底部和安装板6之间上下竖直设置多个，采用加强筋7的方式而不是整体支撑的方式，也能够减小整机的重量。
外桶底31的底壁311上设有排水口，排水口与排水管路10连接，将内桶2、外桶3中的洗涤水排出。
进一步的方案，所述外桶3的桶口低于所述内桶2的桶口。
本实施例的外桶3可以为普通的外桶3，外桶3的桶口与内桶2的桶口平齐或者高于内桶2口，也可以用于桶口低于所述内桶2桶口的外桶3，甚至外桶3可以没有桶体，只保留外桶底31或者与外桶底31类似的结构作为收集结构，收集内桶2中排出的水，腾出空间用来扩大洗衣机内桶2的容积。
本实施例的悬吊减震件4和支撑减震件5均能够对各种高度的外桶3、或者说桶总成起到共同减震、增强桶总成的抗偏能力，尤其是减小低速过共振点时的振动作用。
实施例三
如图1-3所示，本实施例为实施例一或实施例二的进一步的限定，本实施例的洗衣机还包括水平减震件8，所述水平减震件8水平设置于外桶3和洗衣机壳体1之间，并分别与外桶3和洗衣机壳体1连接，减少外桶3和内桶2在水平方向的震动。
由于在洗衣过程中，当内桶2的转速降低到一定范围(一般降低到共振点附近)时，内桶2在水平方向晃动严重，很容易造成外桶3与洗衣机壳体1相撞，造成外桶3和/或洗衣机壳体1的损坏。为了减少外桶3在水平方向的晃动，本实施例设置了水平减震件8，减小洗衣过程中水平震动，增强内桶2和外桶3的抗偏能力，尤其是减小洗衣机转速达到共振点时的振动，减小外桶3撞击洗衣机壳体1的可能。
优选的，所述水平减震件8分别与外桶3和洗衣机壳体1铰接连接，并在竖直方向上设置于悬吊减震件4和支撑减震件5之间。水平减震件8减小水平方向的震动，位于悬吊减震件4和支撑减震件5之间，能够较平均的补充两者在水平减震上的不足，三种减震件能够共同作用，减小洗衣过程中桶总成撞击洗衣机壳体1的几率，可以增强桶总成的抗偏能力，减小低速过共振点时的振动作用，减小洗衣机噪声，增强洗衣过程的安全性，提升用户体验。
进一步的方案，外桶底31包括底壁311和侧壁312，底壁311和侧壁312共同围合形成外桶底31；所述水平减震件8与外桶底31的侧壁312连接，所述支撑减震件5与外桶底31的底壁311连接。此种安装方式，使水平减震件8能够位于悬吊减震件4和支撑减震件5之间，且与外桶3连接，实现对外桶3在水平方向上的减震作用。
优选的，所述外桶底31的侧壁312自下而上直径逐渐增加，所述水平减震件8与外桶底31的侧壁312上直径较小的部位连接。如此，水平减震件8可以活动的范围更大，能够起到 更好的水平减震的效果。
所述水平减震件8设置多个，多个水平减震件8环绕外桶底31的外周壁设置，并且两两相对。两两相对的设置方式，使外桶3的受力更易平衡，更好的防止外桶3撞击洗衣机壳体1的可能。
水平减震件8与悬吊减震件4和支撑减震件5可以上下交错设置，也可以位于同一平面上。水平减震件8、悬吊减震件4和支撑减震件5在水平方向上的投影也可以依次间隔设置，最大程度的分散洗衣机的震动，达到快速减震、防止外桶3偏移撞击洗衣机壳体1的目的。
水平减震件8为水平设置的减震器，包括套筒和连接杆，套筒内设置有减震件，减震件为为弹簧阻尼元件或者为活塞与阻尼气体或者与阻尼液体形成的阻尼机构。连接杆的一端伸入套筒中与减震件连接，另一端与洗衣机壳体1的内壁/与外桶底31的外侧壁312连接，套筒相应的与外桶底31的外侧壁312/与洗衣机壳体1的内壁连接。
具体来说，减震器包括套筒和伸入套筒的活塞杆，套筒内充满液体或气体，活塞杆上伸出套筒的一端与外桶底31侧壁312连接，套筒的底部与洗衣机壳体1的内壁连接。
所述减震器为充气式减震器或液压式减震器。
实施例四
如图4到图7所示，本实施例是实施例一的进一步限定，提供一种悬吊减震件4，包括吊杆41及吊杆41下端套设的减震套筒42，洗衣机的外桶的底部或者外周侧壁设有用于吊挂减震套筒42的安装部，减震套筒42置于安装部下方，吊杆41穿过安装部悬挂在洗衣机的洗衣机壳体上，还包括减震缓冲装置12，所述的减震缓冲装置12套设在吊杆41上，位于安装部和减震套筒42之间，并包覆减震套筒42的上端表面，以减少震动。
悬吊减震件4安装在洗衣机的四个角，洗衣机的外桶的外周侧壁设有安装部，吊杆41组件的下端安装在洗衣机外桶上的安装部中，另一端吊挂在相对应的洗衣机壳体的角上。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42内部设有弹簧组13和用于固定弹簧组13的弹簧座，吊杆41起到连接作用。安装部一般为悬挂座，具有悬挂孔，吊杆41穿过悬挂孔挂到对应位置的洗衣机壳体上，吊杆41下端的减震套筒42则被卡在悬挂孔下部，这样，在洗衣机震动时，吊杆41组件能够起到减小内桶和洗衣机震动的作用。
本实施例的悬吊减震件4中设置的减震缓冲装置12位于安装部和减震套筒42之间，包 覆减震套筒42的上端表面，与现有的减震垫相比，增大了与减震套筒42和安装部的接触面积，因此，在洗衣机震动，悬吊减震件4上下左右移动时，外桶的安装部与减震套筒42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12与减震套筒42和安装部的接触面积都增大，不仅能够更好的减小悬吊减震件4和洗衣机的震动，减震缓冲装置12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42包括一体成型的托架14和套管22，托架14封堵套管22的上端开口；托架14包括沿吊杆41轴向向上延伸的管状凸缘14-1和由管状凸缘14-1向套管22上端开口延伸的过渡结构14-2；所述的减震缓冲装置12设有套设部121和减震部122，套设部121套在管状凸缘14-1上，减震部122包覆过渡结构14-2的外表面。
减震套筒42的托架14和套管15一体成型，封堵套管15的上端口，套管15的下端口由密封盖17密封，减震套筒42内部形成密闭的腔室。弹簧组13被包裹在减震套筒42中，避免被腐蚀损坏。托架14具有沿着吊杆41轴向向上延伸的管状凸缘14-1，向下沿吊杆41轴向延伸形成可以固定弹簧座的固定座。由于管状凸缘14-1的直径小于套筒的直径，管状凸缘14-1的下端需要向外、向下逐渐延伸直至与套管15的上端开口成一体，也就形成了过渡结构14-2。
本实施例的减震缓冲装置12由柔性材料制成，套设部121套在管状凸缘14-1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41组件上下运动的摩擦力，减小震动。减震套筒42和安装部一般由塑料材质制成，减震套筒42上下震动时，容易与安装部撞击，减震部122包覆过渡结构14-2的外表面，相当于减震套筒42的整个上端均由柔性材料覆盖，面积大；减震套筒42与安装部之间均有减震缓冲装置12进行缓冲，减小减震套筒42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121的长度与管状凸缘14-1的长度相同，完全包裹管状凸缘14-1，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121套在管状凸缘14-1的外部，与管状凸缘14-1的外壁保持接触，以产生滑动阻尼。套设部121与管状凸缘14-1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121的内部设有凸起，与管状凸缘14-1的外壁接触，以增大滑动阻尼；套设部121为管状，内壁上可以设置向吊杆41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41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14-1的直径小于套管15的直径，管状凸缘14-1的下缘向外延伸至套管15上端开口，形成过渡结构14-2，过渡结构14-2的外表面为由吊杆41的轴向中心向外倾斜的平面或者曲面；所述的减震部122与过渡结构14-2的外表面相配合，包覆在过渡结构14-2的外部并接触。
由于管状凸缘14-1的直径小于套筒的直径，管状凸缘14-1的下端需要向外、向下逐渐延伸直至与套管15的上端开口成一体，过渡结构14-2的外表面由内向外倾斜，可以在减震套筒42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122包覆在倾斜设置的过渡结构14-2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121的下缘向外延伸，形成减震部122，减震部122的内表面与过渡结构14-2的外表面相配合，减震部122包覆过渡结构14-2，并与套管15的外表面平滑过渡；优选的，减震部122的内表面和过渡结构14-2的外表面为相配合的弧面。
减震部122的大小、形状与托架14的过渡结构14-2相配合。过渡结构14-2为由吊杆41的轴向中心向外倾斜的平面或者曲面，相应的，减震部122也为由套设部121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14-2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42与安装部撞击时，减小受力，减小震动。减震部122与并与套管15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122边缘，或者减震套筒42上端边缘无减震部122覆盖的情况，有利于减小震动。减震部122的内表面和过渡结构14-2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14-2靠近套管15的一端设有周向的环形凹台16，减震部122的边缘与环形凹台16相配合，减震缓冲装置12套设安装到吊杆41上时，减震部122的边缘卡在环形凹台16内。
过渡结构14-2的下端设置周向的环形凹台16，减震部122边缘配合设置，插入到环形凹台16中，可以更好的防止减震缓冲装置12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42的上端，减小减震套筒42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122的边缘沿吊杆41的轴向延伸，其厚度与环形凹台16相配合，并向套管15的外表面平滑过渡。
减震部122外表面由中心向外延伸，边缘处改变方向，沿吊杆41的轴向延伸，可以扣在减震套筒42的上端，防止减震缓冲装置12在震动过程中发生位置的偏移，同时，震动部的边缘向套管15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。
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。
