技术领域
本申请涉及家用电器技术领域，更具体而言，涉及到一种平衡组件及家用电器。
背景技术
洗衣机在脱水阶段，洗涤腔体内洗涤物分布不均匀，存在偏心情况。当洗涤腔体高速旋转时，会产生很大的振动。洗涤腔体上安装平衡环，平衡环内设能够移动的平衡小车，通过控制平衡小车在平衡环内的移动，依靠平衡小车的自身重力和向心力可平衡洗涤腔体内衣物偏心，使洗涤腔体振动趋于减小，进而减少洗衣机的噪音和振动。
在相关技术中，平衡小车的移动依靠驱动轮与平衡环之间的摩擦进行驱动，在该驱动方式中，摩擦力大小不固定会导致平衡小车移动不稳定，而且平衡小车移动时容易打滑。

请参阅图1-图5，本申请实施方式的一种平衡组件100用于家用电器1000。家用电器1000包括平衡组件100、第一腔体200和第二腔体300。第一腔体200能够转动地连接第二腔体300，第一腔体200内可放置负载。平衡组件100包括平衡体10和平衡器20。平衡体10安装在第一腔体200。平衡体10内设有环形的腔室13，平衡器20位于腔室13内。平衡器20能够在腔室13内移动。家用电器1000可以是洗衣机、干衣机等衣物处理电器，或具有能够转动的第一腔体200的其它家用电器1000。负载可以是衣物、被子等需要清洗的物件，或其它物件。
可以理解，在家用电器1000工作时，第一腔体200可相对于第二腔体300转动，第一腔体200内的负载容易分布不均匀，存在偏心的情况。在第一腔体200转动且负载出现偏心的情况下，家用电器1000会产生很大的振动。平衡体10连接固定在第一腔体200，跟随第一腔体200一起转动。因此，可通过控制平衡体10内的平衡器20的移动，依靠平衡器20的自身重力和向心力来抵消或减少第一腔体200转动时的偏心质量，进而可以减小家用电器1000的振动。
在图示的实施方式中，第一腔体200能够转动地设在第二腔体300内。可以理解，在其它实施方式中，第一腔体200与第二腔体300可采用其它连接方式，在此不作具体限定。在本申请的示例中，家用电器1000为洗衣机，可用于洗涤衣物，衣物放置在第一腔体200内。第一腔体200为洗涤腔体(内桶)，第二腔体300可为盛水腔体(外桶)，盛水腔体和洗涤腔体均为圆柱状，洗涤腔体可转动地设在盛水腔体内，盛水腔体和洗涤腔体可设在家用电器1000的壳体(图未示)内。洗涤腔体可具有水平、倾斜或垂直设置的转动轴线X。也即是说，洗涤腔体的转动轴线X相对于水平面平行、倾斜于水平面或者垂直于水平面。可以理解，可以将一个或多个平衡体10设在洗涤腔体的任意位置，平衡体10随洗涤腔体的转动而转动。腔室13的中轴线Y与洗涤腔体的转动轴线X平行或重合，也即是说，平衡体10可以与洗涤腔体同轴设置，也可以相对于洗涤腔体偏心设置。平衡体10也可呈螺旋状布置在洗涤腔体上。
另外，请结合图1，为进一步减少洗衣机内部的振动传递到外部，盛水腔体可通过减振结构连接至安装板400，安装板400可固定在壳体的底板，或为壳体的底板。减振结构可采用弹簧、液压等结构件来减少振动的传递。
请参阅图1-图3，家用电器1000为滚筒洗衣机。第一腔体200包括沿转动轴线X的第一端201和第二端202。第一端201和第二端202分别安装有平衡体10。每个平衡体10的腔室13内设有至少一个平衡器20，例如，一个或两个或多于两个。较佳地，平衡体10的 腔室13内设有两个平衡器20，两个平衡器20的初始平衡位置沿平衡体10的径向对称布置，该布置形式使得第一腔体200在空载状态下可以达到平衡。
具体地，第一腔体200的第二端202可连接有转轴600(请参图17)，转轴600与固定架500转动连接，家用电器1000的动力装置(图未示)可连接转轴600以驱动第一腔体200转动。在图3所示的实施方式中，第一腔体200的第一端201为前端，第二端202为后端，前端可以指朝向用户的一端。在其它实施方式中，第一腔体200的第一端201或第二端202设置有平衡体10，或第一端201和第二端202之间设置有平衡体10。固定架500可以是三脚架。
在图3所示的实施方式中，平衡体10呈圆环状，平衡体10可称为平衡环。可以理解，在其它实施方式中，平衡体10可呈其它形状，例如板状、方环状、椭圆环状等，在此不作具体限定。
请参阅图4，每个平衡体10包括第一环体11和第二环体12，第一环体11和第二环体12共同形成密封的腔室13，腔室13内设置有两个平衡器20。由于平衡体10呈圆环状，平衡器20可在平衡体10的腔室13内作圆周运动。在图3所示的实施例中，第一环体11开设有腔室13，可称为平衡环本体22，第二环体12可称为端盖，第二环体12连接第一环体11以密封腔室13。
请参阅图4，腔室13的内壁131包括第一侧壁1311、第二侧壁1312、第一连接壁1313和第二连接壁1314。第一侧壁1311和第二侧壁1312沿腔室13的径向方向依次间隔设置，第一侧壁1311较第二侧壁1312更靠近腔室13的中轴线Y。第一连接壁1313连接第一侧壁1311和第二侧壁1312，第二连接壁1314连接第一侧壁1311和第二侧壁1312，第二连接壁1314和第一连接壁1313相对设置。具体地，第一环体11包括第一侧壁1311、第二侧壁1312和第一连接壁1313，第二环体12包括第二连接壁1314。在图示的实施方式中，腔室13的中轴线Y与第一腔体200的转动轴线X重合。
请参阅图6-图9，平衡器20包括动力部件21、本体22、支撑结构23、刷丝结构24和平衡控制板25。动力部件21连接平衡控制板25，平衡控制板25设有平衡控制器251以控制平衡器20工作，例如，平衡控制器251控制动力部件21驱动平衡器20在平衡体10的腔室13内移动；又如，控制平衡器20与家用电器1000进行通信等。
具体地，动力部件21包括驱动件211和结合齿轮2121，驱动件211连接结合齿轮2121。请参阅图5和图11，平衡组件100还包括环状的齿部30，齿部30沿平衡体10周向设置在腔室13内，具体地，齿部30设在第一侧壁1311上，结合齿轮2121与齿部30啮合。
可以理解，平衡器20通过结合齿轮2121与齿部30啮合来驱动，啮合具有精度高、传动稳定的特点，不存在打滑的风险，而且结合齿轮2121与设在靠近平衡体10中轴线Y的 第一侧壁1311的齿部30啮合，可以避免由于第一腔体200转动时产生的离心力导致啮合过紧而产生阻力而使得平衡器20驱动困难，从而保证在第一腔体200转动时，特别是高速转动时，平衡器20在腔室13内顺畅及稳定地移动。
在图示的实施方式中，每个平衡器20与齿部30啮合的结合齿轮2121的数量为单个。如此，在第一侧壁1311设置一个环状的齿部30即可，结合齿轮2121和齿部30均为单个，可节约成本。在其它实施方式中，结合齿轮2121的数量可为两个或其它数量，齿部30的数量可根据实际需要设置。两个或多于两个的结合齿轮2121可以和一个齿部30啮合。
可以理解的是，在其它实施方式，齿部30也可以是设置在腔室13的第二侧壁1312上，具体在此不作限制。
请参阅图6，本体22开设有开口221，动力部件21设在本体22，结合齿轮2121部分地从开口221露出。如此，结合齿轮2121从开口221露出的部分与设在第一侧壁1311的齿部30啮合，动力部件21可以通过驱动结合齿轮2121与齿部30的啮合作用使平衡器20移动。需要说明的是，本体22可采用刚度较大的钢板一体成型制成，因此在第一腔体200高速转动时，依然可以保持整个平衡器20的可靠和稳定。可以理解，本体22还可采用其它金属或非金属材质制成，在此不作具体限定。
进一步地，在一些实施方式中，动力部件21还包括调速结构212，调速结构212包括结合齿轮2121，调速结构212连接驱动件211。如此，调速结构212可以调节驱动件211的输出力矩，进而调控平衡器20的移动速度。具体地，请参阅图10，调速结构212包括第一级传动结构2122和第二级传动结构2123，第一级传动结构2122连接驱动件211的输出轴2111，第二级传动结构2123连接第一级传动结构2122和结合齿轮2121。如此，可通过两级传动结构来实现平衡器20的减速比。
请参阅图9和图10，调速结构212可包括箱体2124和位于箱体2124内的第一级传动结构2122和第二级传动结构2123。箱体2124可由牢固的不易变形的厚钢板制成，箱体2124整体呈长方体。在其它实施方式中，箱体2124也可为正方体，棱柱体或圆柱体等其它形状。结合齿轮2121与第二级传动结构2123连接并部分地从箱体2124露出。
具体地，在本申请实施方式中，第一级传动结构2122包括蜗杆21221和蜗轮21222。第二级传动结构2123包括第一齿轮21231和第二齿轮21232。蜗杆21221连接驱动件211的输出轴2111和蜗轮21222，蜗轮21222和第一齿轮21231固定连接，第一齿轮21231和第二齿轮21232啮合，第二齿轮21232连接结合齿轮2121。在图10所示的实施方式中，第二齿轮21232为双联齿轮，双联齿轮分别与第一齿轮21231和结合齿轮2121啮合。在其它实施方式中，第二齿轮21232可为单个齿轮，根据减速比或其它参数选择，在此不作具体限定。
在动力部件21工作的过程中，首先驱动件211通过输出轴2111带动蜗杆21221转动，接着蜗杆21221带动与其配合的蜗轮21222转动，实现第一级传动，进而蜗轮21222带动第一齿轮21231，而后第一齿轮21231带动第二齿轮21232，实现第二级传动。第二齿轮21232带动结合齿轮2121转动，从而带动平衡器20在腔室13内移动。由于蜗轮21222和蜗杆21221具有自锁性能，蜗轮21222和蜗杆21221还可起到限位的作用，在驱动件211不工作的情况下，平衡器20能稳定地停在腔室13内某个位置。
请参阅图9，驱动件211还包括位移检测件80。在动力部件21驱动平衡器20在腔室13内移动的情况下，位移检测件80用于检测输出轴2111转过的圈数，输出轴2111转过的圈数与平衡器20的位置相关。
可以理解，驱动件211可为电机，其输出轴2111为电机轴。在动力部件21驱动平衡器20在腔室13内移动的情况下，输出轴2111转过的圈数与平衡器20的位置是相关的。因此，可以通过检测输出轴2111转过的圈数来确定平衡器20的移动距离，再结合平衡器20的初始平衡位置可以确定平衡器20的位置。初始平衡位置可以指平衡器20在腔室13内开始移动前的位置，或是指在平衡器20移动过程中，能够确定的某个位置。
具体地，位移检测件80包括霍尔传感器和磁性件。霍尔传感器设在驱动件211的输出轴2111并随输出轴2111的转动而转动，磁性件固定设在驱动件211或平衡器20的其它位置，保持不动。当霍尔传感器转动至与磁性件相对的位置时，受磁性件所产生的磁场的影响，霍尔传感器输出脉冲信号，从而可以检测到输出轴2111转过的圈数。磁性件可以是永久磁铁。可以理解，霍尔传感器也可固定不动，磁性件设在驱动件211的输出轴2111并随输出轴2111的转动而转动。
在其它实施方式中，位移检测件80可以是光传感器、超声波传感器等。在一个例子中，光传感器包括光发射件和光接收件，可将光发射件和光接收件的其中一个固定在输出轴2111随输出轴2111的转动而转动，另一个固定设在驱动件211或平衡器20的其它位置，保持不动。输出轴2111转动一圈可使得光接收件接收到发射件发射的光信号，从而可以检测到输出轴2111转过的圈数。超声波传感器的检测原理与光传感器的检测原理类似，在此不再赘述。
在其它实施方式中，位移检测件80是光传感器的情况下，光传感器包括光发射件和光接收件，驱动件211的输出轴2111上设有反射率与输出轴2111反射率不同的部件，例如在驱动件211的输出轴2111上形成有深色涂层。光发射件和光接收件设在输出轴2111斜下方，沿输出轴2111对称布置，光发射件发射的光入射至输出轴2111或该部件上，光接收件接收输出轴2111或该部件反射的光，由于输出轴2111的反射率与该部件的反射率不同，光接收件对应接收到的光信号强度也存在差导，进而在输出轴2111转动过程中，使得 位移检测件80检测到多个脉冲，一个脉冲可对应输出轴2111转过的一圈，或两个脉冲可对应输出轴2111转过的一圈，或多于两个脉冲可对应输出轴2111转过的一圈等，可根据实际情况进行具体标定。
请参阅图5和图6，支撑结构23设在本体22，支撑结构23支撑在腔室13的内壁131上。如此，通过支撑结构23与内壁131的接触，使得平衡器20的运行更稳定。
具体地，支撑结构23包括滚轮231，滚轮231转动地设在本体22，滚轮231接触第二侧壁1312。在平衡器20移动的情况下，滚轮231能够相对本体22转动。可以理解，滚轮231起到承载整个平衡器20离心力及重力的作用。请结合图7，滚轮231可为轴承，通过固定轴2311与本体22连接。固定轴2311与本体22固定连接，固定连接的方式可为焊接的方式、由螺丝连接的方式、卡扣的方式、过盈配合等进行连接，在此不作具体限定。滚轮231套设在固定轴2311上，滚轮231能够相对本体22转动。本体22沿腔室13圆周方向的两端均设有滚轮231，在驱动件211驱动结合齿轮2121带动平衡器20移动的过程中，滚轮231绕固定轴2311转动，并相对本体22转动，使平衡器20在腔室13内更稳定移动。在其它实施方式中，滚轮231可包括转轴和轮子，轮子固定连接转轴，转轴能够转动地连接本体22。轮子的数量可以是一个，或两个或多于两个。
可以理解的是，在其它实施方式中，支撑结构23也可包括滚动件(图未示)，滚动件设置在本体22和第二侧壁1312之间，在平衡器20移动的情况下，滚动件在本体22和第二侧壁1312之间滚动。如此，滚动件的的设置能够减少平衡器20与第二侧壁1312之间的摩擦力以保证平衡器20能够顺畅地在腔室13内移动，同时滚动件的设置也能够起到承载整个平衡器20的离心力的作用。具体地，在这样的实施方式中，滚动件可为滚珠。
进一步地，支撑结构23包括防摩擦件232，防摩擦件232转动地设在本体22，防摩擦件232接触第一连接壁1313和/或第二连接壁1314。在平衡器20移动的情况下，防摩擦件232能够相对本体22转动。如此，进一步限定平衡器20的移动空间，减少平衡器20在其它方向的偏移，同时也可减少平衡器20移动的阻力，提升平衡器20移动的稳定性。可以理解，平衡器20位于密封的腔室13内，在平衡器20移动时，平衡器20期望的移动方向是沿腔室13的圆周方向，而且在移动过程中，平衡器20可能会与第一连接壁1313和/或第二连接壁1314发生摩擦。在本体22上设置与第一连接壁1313和/或第二连接壁1314接触的防摩擦件232，一方面,可以使得平衡器20的移动方向得到修正及限制，另一方面可以有效减小平衡器20与第一连接壁1313和/或第二连接壁1314接触时的摩擦力。
在一个实施方式中，防摩擦件232可转动设在本体22的两侧，位于本体22两侧的防摩擦件232接触第一连接壁1313和第二连接壁1314。在另一个实施方式中，防摩擦件232可转动设在本体22的其中一侧，位于本体22一侧的防摩擦件232接触第一连接壁1313或 第二连接壁1314。
在一个例子中，防摩擦件232包括牛眼轮，本体22与第一连接壁1313和第二连接壁1314接触的两个侧面均设置有牛眼轮，每个侧面间隔设置三个牛眼轮。在其它实施例中，可以是与第一连接壁1313接触的侧面设有牛眼轮，或者是与第二连接部接触的侧壁设有牛眼轮。每个侧面设置的牛眼轮个数可以是一个、两个或其它数量，在此不作具体限定。当然，防摩擦件232可以是其它具有防摩擦作用的物件。
需要说明的是，平衡控制板25设在本体22的其中一个端部。平衡器20还包括设在防撞件26，防撞件26设在本体22的端部。防撞件26相对于平衡控制板25凸出。防撞件26可以保护平衡控制板25不被其它物件碰撞。在图示的实施方式中，防撞件26可为防撞横梁。
请参阅图5、图6和图11-图15，腔室13的内壁131设有导轨结构40，导轨结构40包括导轨41。平衡器20包括刷丝结构24，刷丝结构24包括刷丝241。刷丝241与导轨41能够相对滑动地电连接。如此，平衡体10内的平衡器20可通过导轨41和刷丝241供电和/或通信，平衡器20采用刷丝的方式供电，该供电方式需要部件较少，依靠刷丝241与导轨41的电连接，具有优异的导电性，能够保证供电和/或通信的可靠性。较佳地，刷丝241与导轨41弹性电连接，更能保证供电和/或通信的可靠性。
在一个实施例中，刷丝241本身具有弹性，依靠刷丝241自身的预紧力即可稳定地贴合在导轨41上使刷丝241与导轨41稳定地电连接，无需额外的部件提供预紧力。刷丝241可采用导电性能较佳的铜银合金，导轨41可采用铜导轨41。在另一个实施例中，可利用具备弹性的导轨41与刷丝241电连接，以保证刷丝241与导轨41电连接的可靠性。
具体地，在这样的实施方式中，导轨41形成有环形轨道，刷丝241弹性抵接环形轨道，在平衡器20在腔室13内移动时，刷丝241在环形轨道内移动并保持抵持环形轨道的状态。这样，由于刷丝241弹性力的存在，不论平衡器20在腔室13内如何运动，刷丝241都能有与导轨41保持抵接，从而保证供电和通信的可靠性。
请参阅图13，在某些实施方式中，导轨41包括第一导电导轨411和第二导电导轨412，刷丝241包括第一导电刷丝2411和第二导电刷丝2412，第一导电刷丝2411滑动地连接第一导电导轨411，第二导电刷丝2412滑动地连接第二导电导轨412。如此，通过导电刷丝和导电导轨的电连接，平衡器20可通过导电刷丝从导电导轨获取电能，将电能传输给平衡器20的电部件，例如，平衡控制板25和驱动件211，从而使得平衡器20能够正常工作。
在图13所示的实施方式中，导轨结构40还包括第一导轨座42，第一导电导轨411和第二导电导轨412间隔设在第一导轨座42，第一导轨座42设在腔室13的内壁131，例如第一侧壁1311。刷丝结构24包括刷丝座242，第一导电刷丝2411和第二导电刷丝2412设 在刷丝座242。在其它实施方式中，导轨结构40可省略第一导轨座42，第一导电导轨411和第二导电导轨412可直接设在腔室13的内壁131，例如第一侧壁1311。刷丝结构24可省略刷丝座242，第一导电刷丝2411和第二导电刷丝2412可直接设在平衡器20的本体22。
此外，请参阅图13，在某些实施方式中，导轨41包括第一通信导轨413和第二通信导轨414，刷丝241包括第一通信刷丝2413和第二通信刷丝2414，第一通信刷丝2413滑动地连接第一通信导轨413，第二通信刷丝2414滑动地连接第二通信导轨414。如此，通过通信导轨和通信刷丝的电连接，平衡器20可通过通信刷丝和通信导轨与控制器60互相通信，例如，平衡器20从控制器60获取移动指令，平衡器20向控制器60反馈其当前位置信息等等。
在图13所示的实施方式中，导轨结构40包括第二导轨座43，第一通信导轨413和第二通信导轨414间隔设在第二导轨座43，第二导轨座43设在腔室13的内壁131，例如第一侧壁1311。刷丝结构24包括刷丝座242，第一通信刷丝2413和第二通信刷丝2414设在刷丝座242。在其它实施方式中，导轨结构40可省略第二导轨座43，第一通信导轨413和第二通信导轨414可直接设在腔室13的内壁131，例如第一侧壁1311。刷丝结构24可省略刷丝座242，第一通信刷丝2413和第二通信刷丝2414可直接设在平衡器20的本体22。
请参阅图15，刷丝座242的两侧均设有第一导电刷丝2411、第二导电刷丝2412、第一通信刷丝2413、第二通信刷丝2414。这样，可以进一步提升输电和通信的可靠性。在一侧的导电刷丝和/或通信刷丝故障的情况下，另一侧的导电刷丝仍能够实现输电，通信刷丝仍能实现通信。在其它实施方式中，可以理解，可以在刷丝座242的一侧设置第一导电刷丝2411、第二导电刷丝2412、第一通信刷丝2413、第二通信刷丝2414，以节约成本。
可以理解的是，在本申请的实施方式中，每一个导电导轨和通信导轨均形成有环形轨道，也即是说，第一导电导轨411、第二导电导轨412、第一通信导轨413和第二通信导轨414均形成有环形轨道，从而使得第一导电刷丝2411、第二导电刷丝2412、第一通信刷丝2413和第二通信刷丝2414均能够与对应的环形轨道弹性抵接。
另外，请参阅图5和图15，在本申请的实施方式中，刷丝241呈细长状，刷丝241连接在刷丝座242上，刷丝241与导轨41相对设置，刷丝241的中间部分朝导轨41所在一侧弯折以使刷丝241弹性抵持导轨41的环形轨道。
如此，刷丝241的弯折部分抵持导轨41，这样可以使得刷丝241与导轨241连接的可靠性。
具体地，在这样的实施方式中，在安装平衡器20前，刷丝241处于正常状态，在安装过程中，首先可将平衡器20的本体22安装在腔室13内，然后将刷丝241弯折后使得刷丝241发生一定量的弹性形变从而将刷丝241放置在腔室13内以抵持导轨31的环形轨道。
再有，请参阅图11，在图示的实施方式中，其中，第一导电导轨411、第二导电导轨412、第一通信导轨413和第二通信导轨414均沿腔室13的内壁131周向设置，第一导电导轨411和第二导电导轨412位于齿部30的一侧，第一通信导轨413和第二通信导轨414位于齿部30的另一侧。也即是说，齿部30设置在导电导轨和通信导轨之间且位于腔室13的中间位置，从而使得结合齿轮2121也位于腔室13的中间位置。这样，结合齿轮2121与齿部30的和啮合以及支撑结构23可以共同对平衡器20进行有效的支撑以防止平衡器20晃动。
在上述实施方式中，导轨41设在腔室13的第一侧壁1311上。可以理解的是，在其它实施方式中，导轨41也可以是设置在第二侧壁1312上，刷丝241位于靠近第二侧壁1312的一侧且也导轨41滑动电连接。在这样的实施方式中，导轨41形成有环形轨道，滚轮231可以位于环形轨道内，在平衡器移20移动的情况下，滚轮231在环形轨道内移动。
如此，刷丝241与滚轮231共用一个环形轨道，环形轨道在于刷丝241连接的同时也能够引导滚轮运动，滚轮231位于环形轨道内可以有利于控制滚轮231的运动轨迹，防止滚轮231发生偏移，同时刷丝231和滚轮231共用一个轨道可以简化平衡组件100的结构，而无需设置另外的导向结构引导滚轮231的运动。
请参阅图16-图19，平衡组件100包括无线收发装置50和控制器60。无线收发装置50包括第一无线收发件51和第二无线收发件52。第一无线收发件51用于安装在第一腔体200，第二无线收发件52用于安装在第二腔体300。第一无线收发件51与第二无线收发件52间隔相对设置，控制器60连接第一无线收发件51。
可以理解，控制器60通过第一导线61连接第一导电导轨411、第二导电导轨412、第一通信导轨413和第二通信导轨414。控制器60可从第一无线收发件51和第二无线收发件52获取电能并将电能通过第一导线61传输至第一导电导轨411和第二导电导轨412，从而使得平衡器20可通过第一导电刷丝2411和第二导电刷丝2412从第一导电导轨411和第二导电导轨412获取电能。
控制器60可以通过第一导线61、第一通信导轨413、第二通信导轨414、第一通信刷丝2413和第二通信刷丝2414与平衡器20通信。具体地，在一个实施方式中，控制器60可以通过第一导线61将平衡器20的移动指令传输至第一通信导轨413和第二通信导轨414，从而使得平衡器20可通过第一通信刷丝2413和第二通信刷丝2414从第一通信导轨413和第二通信导轨414获取对应的移动指令。在另一个实施方式中，平衡器20可通过第一通信刷丝2413和第二通信刷丝2414将平衡器20的当前位置信息传输至第一通信导轨413和第二通信导轨414，从而使得控制器60可通过与第一通信导轨413和第二通信导轨414连接的第一导线61获取平衡器20的当前位置信息。在其它实施方式中，控制器60和 平衡器20之间还可交互其它信息和指令。
具体地，第一无线收发件51包括第一线盘511和第一电路板512，第二无线收发件52包括第二线盘521和第二电路板(图未示)。在向平衡器20供电时，第二线盘521用于在通电的情况下产生变化的磁场，第一线盘511用于在感应到变化的磁场的情况下产生感应电流。第一腔体200安装有转轴600，转轴600能够转动地连接第二腔体300，家用电器1000的动力装置连接转轴600以驱动第一腔体200转动。请结合图2、图16和图19，第一腔体200的后端固定连接有固定架500，固定架500转动连接转轴600。转轴600为中空转轴。第一线盘511可通过第一支架513安装于转轴600的一端，第一线盘511通过穿设转轴600内部的第二导线514连接第一电路板512，第一电路板512连接控制器60。第二线盘521可通过第二支架522安装在第二腔体300的外表面，第二线盘521连接第二电路板，第二电路板连接家用电器1000的电源线，电源线连接市电。如此，将外部电能以无线输电的形式将电能传输给控制器60，以通过控制器60将电能传输至平衡器20。
在图示的实施方式中，固定架500为三脚架，其包括第一脚架501、第二脚架502和第三脚架503。其中，第一脚架501安装有控制板62，控制器60设在控制板62上；第二脚架502安装有第一电路板512；第三脚架503安装有平衡板504。这样，平衡板504可以平衡第一电路板512和控制板62带来的偏心，使三脚架保持平衡，减少振动量的产生。
请参阅图5和图20，平衡组件100包括标识件70和位移检测件80。在平衡器20在腔室13内移动的情况下，标识件70与位移检测件80发生相对运动，位移检测件80用于检测标识件70经过位移检测件80的次数，标识件70经过位移检测件80的次数与平衡器20的位置相关。如此，位移检测件80可检测标识件70经过位移检测件80的次数，进而能够获取平衡器20的移动距离，从而可以确定平衡器20的位置。
可以理解，在平衡器20在腔室13内移动的情况下，标识件70与位移检测件80发生相对运动而经过位移检测件80，而标识件70经过位移检测件80的次数与平衡器20的位置是相关的。因此，可以通过检测标识件70经过位移检测件80的次数来确定平衡器20的移动距离，再结合平衡器20的初始平衡位置可以确定平衡器20的位置。
具体地，可利用结合齿轮2121的齿作为标识件70，这样可无需另外设置标识件。当然，也可以利用齿部30的齿作为标识件70。位移检测件80包括光传感器、霍尔传感器、超声波传感器的至少一种。下文以结合齿轮2121的齿为标识件70，位移检测件80为光传感器为例进行详细说明。
结合齿轮2121的齿之间具有凹槽，齿与凹槽均匀交错分布。结合齿轮2121与齿部30啮合转动，在结合齿轮2121转动的情况下，可带动平衡器20移动。在这种情况下，结合齿轮2121的齿可作为标识件70，对应地，位移检测件80可安装于平衡器20上正对着结 合齿轮2121的齿或凹槽的位置。在结合齿轮2121转动时，位移检测件80相对不动。在结合齿轮2121转动的过程中，结合齿轮2121的齿和凹槽会不断交替地经过位移检测件80，因此，可以检测结合齿轮2121的齿经过位移检测件80的次数，即结合齿轮2121经过位移检测件80的齿数。可以理解，在其它实施方式中，也可以将两个齿之间的凹槽作为标识件。
在位移检测件80为光传感器的情况下，光传感器包括光发射件和光接收件，光发射件和光接收件可设在结合齿轮的同一侧，或分别设在结合齿轮的相背两侧。由于结合齿轮2121的齿对光发射件发射的光有遮挡作用，而凹槽对光发射件发射的光无遮挡作用。在光发射件和光接收件设在结合齿轮同一侧的情况下，光接收件可接收到齿反射回来较强的光信号强度，而凹槽无反射回来的光信号强度，或凹槽反射回来较弱的光信号强度(可能是由于凹槽以外的其它部件反射回来的光线)，经过平衡控制器251可处理得到有规律的脉冲信号，脉冲的数量即结合齿轮2121转动的齿数，由此可以得到平衡器20的移动距离，再结合平衡器20的初始平衡位置可以得到平衡器20的位置。在光发射件和光接收件分别设在结合齿轮相背两侧的情况下，光接收件可接收到穿过凹槽较强的光信号强度，因齿对光线遮挡而无接收到或接收到较弱的光信号强度，经过平衡控制器251可处理得到有规律的脉冲信号，脉冲的数量即结合齿轮2121转动的齿数，由此可以得到平衡器20的移动距离，再结合平衡器20的初始平衡位置可以得到平衡器20的位置。在一个例子中，光发射件可以发光二极管(如可见光发光二极管，或红外发光二极管)，光接收件可为光电二极管。
在其它实施方式中，可利用黑白相间的条纹作为标识件70，对应地，位移检测件80可采用光传感器。
在本申请实施方式中，腔室13设有初始平衡位置。平衡控制器251电连接位移检测件80，平衡控制器251用于根据标识件70经过位移检测件80的次数和初始平衡位置确定平衡器20的位置。如此，方便对平衡器20所在的位置进行确定。
可以理解，在平衡器20没有移动的情况下，平衡器20的初始平衡位置指平衡器20静止在腔室13内时的默认位置。平衡控制器251记录有初始平衡位置，在平衡器20从默认位置开始移动的情况下，再结合平衡器20移动过的距离即可确定平衡器20的位置。具体地，位移检测件80根据标识件70经过位移检测件80的次数可输出有规律的脉冲信号，平衡控制器251接收位移检测件80输出的脉冲信号经并经过处理得到平衡器20的移动距离，再结合平衡器20的初始平衡位置，最终可计算得到平衡器20的当前位置。平衡器20的当前位置信息可发送到控制器60。
在本申请实施方式中，腔室13内可设有多个(两个或多于两个)初始平衡位置。在腔室13内有多个(两个或多于两个)平衡器20的情况下，每个初始平衡位置均停留有对应的一个平衡器20。在一个实施方式中，腔室13内设有两个初始平衡位置，平衡器20的数量为两 个。在两个平衡器20没有移动的情况下，每个初始平衡位置均静止地停留有一个平衡器20。较佳地，两个初始平衡位置成180度对称布置。这样，在平衡器20没有移动的情况下，可使平衡体10保持平衡，进而保持第一腔体200的平衡，防止在第一腔体200转动时引入不必要的振动。在其它实施方式中，初始平衡位置的数量可以是三个或多于三个，具体位置可根据需要设置，在此不作具体限定。
请参阅图5，平衡组件100包括校正件90和校正检测件110。在平衡器20在腔室13内移动的情况下，校正件90与校正检测件110发生相对移动，校正检测件110用于检测校正件90以消除平衡器20的位置误差。
可以理解，由于平衡器20长时间移动，位移检测件80检测驱动件211的输出轴2111转过的圈数或位移检测件80检测标识件70经过位移检测件80的次数时可能会出现累计的误差。而通过有误差的次数信息来计算平衡器20的移动距离时，会导致所确定的平衡器20的位置出现误差。因此，可通过设置校正件90和校正检测件110来消除平衡器20的位置误差。
具体地，当校正检测件110经过每一个校正件90时，其检测到校正件90的信息会传输到平衡控制器251。进一步地，平衡控制器251获取平衡器20经过了校正件90所在的位置的信息，会将平衡器20所处的该位置设定为0值，即可视为起始点重新计算平衡器20的移动距离，以避免因平衡器20的长时间移动产生累积的距离误差，导致无法精确判断平衡器20的位置。在本实施例中，当校正检测件110经过每一个校正件90后，位移检测件80检测驱动件211的输出轴2111转过的圈数或位移检测件80检测标识件70所经过的次数通过脉冲信号的方式从0开始再次反馈到平衡控制器251，平衡控制器251对平衡器20的移动距离会再次开始计算，并得出平衡器20所处于平衡体10的精准位置信息。
请结合图21，腔室13内设置有两个校正件90，两个校正件90沿平衡体10径向成180度对称布置，每个校正件90的位置可对应于一个初始平衡位置。校正件90设在腔室13的内壁131。其中一个校正件90包括凸起的一个校正部，另一个校正件90包括凸起的两个校正部，通过对结构特征不同来区分平衡器20经过的是哪个校正件90，进而可以确定平衡器20位于哪个初始平衡位置。
校正检测件110可以是光传感器、超声波传感器、霍尔传感器中的其中一个。校正检测件110经过不同结构的校正件90会触发不同的脉冲信号，脉冲信号的脉冲个数与校正件90上的校正部的数量相同，从而可以根据校正检测件110输出的脉冲信号确定平衡器20正经过某个校正件90，从而确定平衡器20在腔室13内的具体位置。如此，可以在腔室13内定位平衡器20的位置。在其它实施方式中，校正件90的数量可设置三个、四个或多于四个，每个校正件90包括不同数量的校正部即可。校正件90的数量和位置及校正件90的 校正部的数量可根据具体情况进行调整，不限于上述实施方式。
需要说明的是，校正件90可对应于初始平衡位置，在平衡器20工作结束后，可利用校正检测件110和校正件90的配合使平衡器20回到初始平衡位置，从而实现平衡器20的复位。另外，校正件90可安装在一环状件91上，齿部30是一齿圈31的齿部，在图13的示例中，环状件91、第一导轨座42、齿圈31和第二导轨座43依次并列设在腔室13的第一侧壁1311。可以理解，在其它实施方式中，校正件90和/或齿部30可直接形成在第一侧壁1311上。
综上，本申请实施方式的一种平衡组件100用于家用电器1000。家用电器1000包括能够转动的第一腔体200。平衡组件100包括平衡体10、平衡器20和环状的齿部30。平衡体10用于安装在第一腔体200，平衡体10内设有环形的腔室13。腔室13的内壁131包括第一侧壁1311和第二侧壁1312。第一侧壁1311和第二侧壁1312沿平衡体10径向设置，第一侧壁1311较第二侧壁1312更靠近腔室13的中轴线Y。平衡器20位于腔室13内。平衡器20包括动力部件21，动力部件21包括驱动件211和结合齿轮2121，驱动件211连接结合齿轮2121。齿部30沿平衡体10周向设置，齿部30设在第一侧壁1311上，结合齿轮2121与齿部30啮合。
上述实施方式的平衡组件100中，平衡器20通过结合齿轮2121与齿部30啮合来驱动，啮合具有精度高、传动稳定的特点，不存在打滑的风险，而且结合齿轮2121与设在靠近平衡体10中轴线Y的第一侧壁1311的齿部30啮合，可以避免由于第一腔体200转动时产生的离心力导致啮合过紧而产生阻力而使得平衡器20驱动困难，从而保证在第一腔体200转动时，特别是高速转动时，平衡器20在腔室13内顺畅及稳定地移动。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施方式，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
