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
一种洗衣机，包括箱体100、设置于箱体100内的洗衣桶组件和设置在洗衣桶组件下部的驱动装置300，还包括与洗衣桶组件和/或驱动装置300固定连接的固定结构800和设置在箱体100底部的支撑结构900，固定结构800支撑于支撑结构900上将洗衣桶组件和驱动装置300支撑在箱体100内，固定结构800与支撑结构900相互配合使支撑结构900为固定结构800提供多个方向的支撑力。
方案一，洗衣桶组件包括内桶200和设置在内桶200外的外桶，固定结构800与外桶和/或驱动装置300固定连接。
方案二，洗衣桶组件包括内桶200，所述内桶200为盛水桶，内桶200外不设外桶，固定结构800与驱动装置300固定连接，驱动装置300与内桶200的底壁连接驱动内桶200转动，因此固定结构800与驱动装置300和内桶200成为一个整体。
以下实施例以只含有内桶200，内桶外不设外桶的洗衣机进行解释。
在洗衣时，由于衣物分布不均使内桶重心偏移，很容易造成内桶200晃动，产生噪音。为减少噪音，一般通过在箱体100内设置支撑类减震件700或者悬吊式减震件来达到减震的效果。减震件700一般环绕内桶200设置一周才能达到各个方向的支撑，但是由于减震件700成本高，一般设置数量有限，这就会造成在某些方向无法起到支撑效果或者减震支撑、效果较小。
通过设置固定结构800和支撑结构900，固定结构800与支撑结构900相互配合使支撑结构900为固定结构800提供多个方向的支撑力，当内桶200重心发生偏移时，如果该方向上没有支撑件805或者没有悬吊式减震件给予支撑，可以通过支撑结构900提供的支撑力，减少其偏移、晃动，达到较好的减震效果，使内桶200和驱动装置300震动更小。通过固定结构800和支撑结构900将内桶200和驱动装置300支撑于箱体100内，可以不使用悬吊式减震件将内桶200和驱动装置300悬起，无悬吊式减震件占用内桶200与箱体100之间的空间，有助于扩大内桶200的直径，为洗衣机的扩容提供可能。
进一步地，支撑结构900具有支撑所述固定结构800的支撑部901，所述固定结构800具有与支撑部901相匹配的配合部801，所述支撑部901和配合部801均具有多个朝向不同方向的侧面，当内桶200重心偏移时，支撑部901与配合部801配合为固定结构800提供垂直于侧面的支撑力。
上述支撑结构支撑固定结构所表述的意思是，由于固定结构与内桶和驱动装置固定成为一个整体，支撑结构对固定结构的支撑，其实质是支撑结构对固定结构及与固定结构固定连 接的内桶和驱动装置形成的整体的支撑，将内桶和驱动装置支撑于箱体内。
支撑结构900具有支撑部901，固定结构800通过支撑部901与配合部801的配合将固定结构800支撑于支撑结构900上，支撑部901具有多个朝向不同的侧面，配合部801具有与支撑部901相配合的多个侧面，当内桶200重心偏移时，支撑部901为固定结构800提供垂直于侧面的支撑力，实现支撑部901对固定结构800的多方向支撑。
进一步地，所述支撑部901与配合部801均具有弧面，由于弧面具有多个侧面，所述支撑部901的弧面与配合部801的弧面相互配合，当内桶200重心偏移时，支撑部901为固定结构800提供垂直于弧面的支撑力。弧面上的每个点对应一个方向，当内桶200重心发生偏移时，能够提供的支撑力的方向更多，支撑效果更好。
进一步地，所述支撑部901与配合部801的弧面均为球面，所述支撑部901的球面与配合部801的球面相互配合，使支撑结构为固定结构提供垂直于球面的支撑力。
由于球面更加光滑且为对称图形，因此，对于固定结构800、内桶200和驱动装置300的支撑更易于平衡，而且球面为中心对称图形，即使在震动和晃动过程中，内桶200和驱动装置300发生扭转力，也能被吸收，减少内桶200和驱动装置300的扭转损坏；内桶200与驱动装置300通过固定结构800支撑于支撑结构900上，使内桶200与驱动装置300均不与支撑结构900直接接触，减少震动或晃动造成的内桶和/或驱动装置的损坏，而且固定结构800在震动或晃动时还能具有一定的缓冲作用，减轻震动。
进一步地，所述支撑部901为设置在支撑结构900上的凸起802，所述配合部801为设置固定结构800上与支撑部901相匹配的凹槽902，
或者，所述支撑部901为设置在支撑结构900上的凹槽902，所述配合部801为设置固定结构800上与支撑部901相匹配的凸起802；
所述凸起802的表面为外圆弧面，所述凹槽902的内壁为内圆弧面，凸起802的外圆弧面与凹槽902的内圆弧面接触配合。
凸起802的外圆弧面与凹槽902的内圆弧面接触，当内桶200重心发生偏移时，圆弧面为固定结构800提供垂直于圆弧面的直接支撑力，阻止内桶和驱动装置的进一步晃动。
进一步地，所述凸起802的表面为外球面，凹槽902的内壁为内球面，凸起802的外球面与凹槽902的内球面配合为固定结构800提供垂直于球面的支撑力。
最好，内桶200与驱动装置300共轴线，凸起802和凹槽902球面的中心均位于内桶200的中轴线上。
进一步地，所述支撑结构900具有支撑所述固定结构800的支撑板903，支撑板903水平放置，所述固定结构800具有与所述支撑板903相对的固定板803，所述凹槽902/凸起802分别设置在支撑板903和固定板803上，所述凸起802与固定板803或与支撑板903一体成型或者可拆卸连接。
支撑结构900的上部具有支撑板903，固定结构800的下部具有与支撑板903相对的固定板803，支撑板903和固定板803之间通过凹槽902和凸起802连接，也就是说，凸起802插入凹槽902内并且二者的接触面为球面，当内桶200重心偏移时，在球面上产生垂直于球面的支撑力，使内桶200和驱动装置平衡。
固定板803与支撑板903相对设置，能够较好的提供支撑力，最好，凸起802与凹槽902设置在内桶200的中轴线上，使整体结构上更加对称，更易平衡。
方案一，所述固定板803位于所述支撑板903的上方，所述支撑板903局部向上凸出形成外球形的凸起802，所述固定板803局部向上凹陷形成内球形的凹槽902，外球形和内球形均为半球且球径相等，凸起802支撑于凹槽902内，凸起802的外球面与凹槽902的内球面贴合，当内桶200和驱动装置300晃动带动固定结构晃动时，由于凸起和凹槽的球面配合，使凸起802为固定结构800提供垂直于凸起外球面的支撑力。
方案二，所述固定板803位于所述支撑板903的上方，所述固定板803向下凸出形成球形的凸起802，所述支撑板903向下凹陷形成凹槽902，凹槽902的内壁为球形，凸起802支撑于凹槽902内，凸起802的外球面与凹槽902的内球面贴合，当内桶200晃动时，支撑板903的凹槽802为固定结构800提供垂直于凹槽内球面的支撑力。
所述固定结构800具有一容纳空间，所述驱动装置300位于该容纳空间内，并与固定结构800固定连接。通过设置容纳腔，使固定结构800不仅对内桶200和驱动装置300具有固定、支撑作用，还具有保护驱动装置300的作用。
进一步地，固定结构800还包括安装板500和支撑件805，所述支撑件805的两端分别与安装板500和固定板803连接，使安装板500与固定板803间隔一定间距形成容纳空间，所述驱动装置300位于该容纳空间内并且固定在安装板500的下部，驱动装置300穿过安装板500与内桶连接，驱动内桶转动。支撑件805将安装板500和固定板803间撑开一定间距，形成可容纳驱动装置300的容纳空间，驱动装置300被环绕在容纳空间内，固定结构800对驱动装置300具有一定的保护作用。
方案一，所述支撑件805为支撑柱805-1，所述支撑柱805-1的上端与安装板500固定 连接，下端与固定板803连接，使安装板500与固定板803之间间隔一定距离形成容纳空间。
支撑柱为多根，最好为4根以上，多根支撑柱环绕安装板均匀分布。
支撑柱805-1、固定板803和安装板500将驱动装置300环绕在容纳空间内，对驱动装置300起到一定的保护作用，同时，在进行洗衣机的维修与更换时，固定结构800还具有支撑的作用，方便对驱动装置300进行检查、维修和更换。
方案二，所述支撑件805为固定板803的边沿向上延伸形成的桶状侧壁805-2，所述桶状侧壁805-2与固定板803围成开口向上的凹腔806，所述驱动装置300位于该凹腔806内，所述安装板500与凹腔806的开口边沿固定连接。
最好，安装板500与凹腔806的开口边沿可拆卸连接，可以通过螺钉连接或者卡接。
该结构中将凹形空间807设计成一封闭的凹腔806，能够实现很好的防水效果，由于内桶200为盛水桶，其外不具有外桶，内桶200中的水如果溢流，很容易损坏驱动装置300，通过将其设计成封闭结构，溢流的水不易与驱动装置300接触，对驱动装置300起到更好的保护作用。
进一步地，洗衣机还包括减震件700，所述减震件700的一端与安装板500固定连接，另一端与支撑结构900连接。
通过设置减震件700，利用减震件700的缓冲作用，进一步减少内桶200的震动，另外也对球形凸起802具有一定的保护作用。
减震件700可以是减震弹簧、减震器、座簧、液压缸等可以起缓冲作用的部件。如图1所示，减震件为减震弹簧，如图3所示，减震件为减震器。
进一步地，所述减震件700的上端与安装板500固定连接，下端与支撑板903固定连接。
支撑板903最好为支撑平板，支撑平板的边沿与箱体100的内壁贴合，由于受箱体100材质的影响，减震件700与箱体100直接安装的话，容易在拉拽力的作用下损坏，由于支撑板面积小，可以采用不同于箱体的抗拉强度较高的材质，延长支撑板903使用寿命，同时结构简单，成本低，抗拉性好。
实施例二
如图1-4所示，在实施例一的基础上，本实施中固定结构上设有用于阻挡从内桶200中排出的水溢出的挡水结构，所述挡水结构整体位于所述内桶200桶底的下部，内桶200具有盛水功能。
具体来说，挡水结构设置在安装板500的上部。
通过设置挡水结构，一方面当水从内桶200排出时，通过挡水结构将水阻挡，防止水的溢出，另一方面，由于挡水结构整体位于内桶200以下，使挡水结构不具有位于内桶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。
所述挡水结构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整体位于洗衣桶组件的桶底以下，对于只具有内桶的洗衣机来说，集水腔400整体位于内桶的桶底下方，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和挡水结构之间设置一定的安全距离，防止内桶200碰撞到挡水结构造成损坏，同时也不用在挡水结构和箱体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，防止内桶震动时与集水腔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上设有用于将挡水结构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与挡水结构连通。通过第一排水口201连通的第一排水管路202将内桶内的水排入挡水结构，进而通过排水管401将水排出。
实施例三
如图1-4所示，本实施例为对实施例二的进一步限定，本实施例中所述安装板500上设有挡水筋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内设置用于将挡水结构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，由于内桶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与挡水结构连通，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中的水直接排入挡水结构，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，将水排入挡水结构中。
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，自动流入挡水结构，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。
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。
