请参阅图1-图5,本申请实施方式的平衡组件100用于家用电器1000。家用电器1000包括本体200、腔体300和平衡组件100。腔体300能够转动地连接本体200,腔体300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安装在腔体300,平衡体10内设有腔室12,平衡器20可以在平衡体10的腔室12内移动。家用电器1000可以是洗衣机、干衣机等衣物处理电器,或具有可转动的腔体300的其它家用电器。
可以理解,在家用电器1000工作时,腔体300高速转动,腔体300内的负载容易分布不均匀,存在偏心的情况。当腔体300高速转动时,家用电器1000会产生很大的振动。平衡体10连接固定在腔体300,跟随腔体300一起转动。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腔体300转动时的偏心质量,进而可以减小家用电器1000的振动。具体地,请参阅图6和 图7,家用电器1000包括主控制器400,平衡器20包括控制器22,主控制器400可与控制器22通信。主控器可以根据家用电器1000的振动信号(如本体200的振动信号)生成移动指令,控制器22根据接收到移动指令控制平衡器20移动一定距离。主控制器400和控制器22可以通过有线的方式连接通信,也可以通过无线的方式连接通信。
在图示的实施方式中,腔体300能够转动地设在本体200内。可以理解,在其它实施方式中,腔体300与本体200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,衣物放置在腔体300内。腔体300为洗涤腔体300(内桶),本体200可包括壳体和盛水腔体210(外桶),盛水腔体210和洗涤腔体300均为圆柱状,洗涤腔体300可转动地设于盛水腔体210内,盛水腔体210和洗涤腔体300可设置在壳体内。洗涤腔体300可具有水平、倾斜或垂直设置的传动轴线X。也即是说,洗涤腔体300的传动轴线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设置在洗涤腔体300的任意位置,平衡体10随洗涤腔体300的转动而转动。平衡体10的中心轴线与洗涤腔体300的传动轴线X平行或重合,也即是说,平衡体10可以与洗涤腔体300同轴设置,也可以相对于洗涤腔体300偏心设置。平衡体10也可呈螺旋状布置在洗涤腔体300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210可通过减振结构500连接至安装板600,安装板600可固定在壳体的底板,或为壳体的底板。减振结构500可采用弹簧、液压等结构件来减少振动的传递。
请参阅图2和图3,家用电器1000为洗衣机。腔体300包括沿传动轴线X的第一端302和第二端304。第一端302和第二端304分别连接有平衡体10。每个平衡体10的腔室12内设有至少一个平衡器20,例如,一个或两个或两个以上。较佳地,平衡体10的腔室12内设有两个平衡器20,两个平衡器20的初始位置121成对称布置,该布置形式使得腔体300在空载状态下可以达到平衡。
具体地,腔体300的第二端304与固定架700固定连接,固定架700可连接转轴800,家用电器1000的动力装置(图未示)可连接转轴800以驱动腔体300转动。在图示的实施方式中,腔体300的第一端302为前端,第二端304为后端,前端可以指朝向用户的一端。在其他实施方式中,腔体300的第一端302或第二端304设置有平衡体10,或第一端302和第二端304之间设置有平衡体10。固定架700可以是三脚架。
在图示的实施方式中,平衡体10呈环状,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可呈其他形状,例如板状,在此不作具体限定。请参阅图4、图5和图8,平衡体10包括承载圈14、端盖16、环状的连接件18和环座11。环座11内形成有腔室12,端盖16连接环座11并密封腔室12,承载圈14安装在腔室12的内壁122上。连接件18的数量可为两个,分别安装在承载圈14的两侧。由于平衡体10呈环状,平衡器20可在平衡体10的腔室12内作圆周运动。
请参阅图4、图5和图9-图12,平衡器20包括支架24、控制仓26、驱动组件28、承载结构21和第一导向结构23。控制仓26、驱动组件28和第一导向结构23安装在支架24,驱动组件28设在承载结构21上。控制仓26内置有控制板,平衡器20的控制器22设置于控制板。驱动组件28连接控制板,控制板上的控制器22可以控制驱动组件28驱动平衡器20在腔室12内移动。承载结构21与腔室12的内壁122接触并用于在平衡器20移动的过程中,沿着腔室12的内壁122运动以承担平衡器20在腔室12内运动时所受到的离心力作用。
可以理解,在家用电器1000的腔体300高速转动的过程中,由于腔体300做圆周运动而产生离心力,而平衡体10固定在腔体300上,平衡体10的腔室12内的平衡器20会受到腔体300高速转动的离心力作用,影响平衡器20在腔室12内的正常移动。承载结构21可承担由于腔体300高速转动而产生的离心力作用,避免了平衡器20所受到的离心力增大驱动组件28与平衡体10的摩擦力,承载结构21的设置能够使得驱动组件28较容易驱动平衡器20在腔室12内移动。
具体地,承载结构21整体由金属材料制成,牢固且不易变形,能稳定地承载整个驱动组件28,保证驱动组件28的正常工作。在平衡器20移动的过程中,承载结构21沿腔室12的内壁122运动,通过与腔室12的内壁122的接触,承担平衡器20在腔体300圆周运动下的离心力作用。在本申请实施方式中,承载结构21能够保证即使在腔体300转速大于或等于800rpm高速旋转的情况下,平衡器20也能正常移动。支架24可采用金属材料制成,例如厚不锈钢钢板制成,用于固定控制仓26及平衡器20的其它组成部分。如此,可避免平衡器20在工作过程中出现平衡器20的零部件散落的情况,在平衡器20的整个工作过程中支架24不会发生变形。
请参阅图4、图5、图9和图10,驱动组件28包括驱动件282和转动件284,驱动件282连接转动件284。驱动件282用于驱动转动件284转动以带动平衡器20在腔室12内移动。如此,通过驱动组件28带动平衡器20移动,可改变平衡器20在腔室12内的位置,以减小家用电器1000的振动。
具体地,驱动件282包括电机,电机用于驱动转动件284转动,进而带动平衡器20在腔室12内移动,实现平衡器20快速减小或抵消腔体300的偏心质量,从而减小家用电器1000的振动。通过控制电机的正转、反转或停止转动,可以控制平衡器20沿顺时针方向或逆时针方向移动或停止移动。腔室12内设有环状的连接件18,连接件18的内侧设有齿部,转动件284包括齿轮2842,齿轮2842与齿部啮合。如此,通过齿轮2842与齿部的啮合来带动平衡器20的移动,可防止平衡器20在移动过程中出现打滑,保证了平衡器20移动的稳定性。在图示的实施方式中,腔室12包括内壁122,内壁122设有承载圈14,承载圈14的两侧设有连接件18,连接件18的齿部的模数为1或1.25。在其它实施方式中,承载圈14可以省略,连接件18可直接设在腔室12的内壁122。
进一步地,驱动组件28包括调速结构286,调速结构286连接驱动件282和转动 件284。如此,通过调速结构286,可进一步控制平衡器20的移动速度。具体地,请参阅图13和图14,调速结构286包括第一级传动结构2862和第二级传动结构2864,第一级传动结构2862连接驱动件282的输出轴2822(电机的输出轴2822),第二级传动结构2864连接第一级传动结构2862和转动件284。如此,可通过两级传动结构来实现平衡器20的减速比。
可以理解,调速结构286可包括箱体2866和位于箱体2866内的第一级传动结构2862和第二级传动结构2864。箱体2866可由牢固的不易变形的厚钢板制成,箱体2866整体呈长方体。在其他实施方式中,箱体2866也可为正方体,棱柱体或圆柱体等其它形状。在图示的实施方式中,腔室12的内壁122设有两个连接件18,转动件284包括两个齿轮2842,两个齿轮2842分别位于箱体2866的两侧且分别与两个连接件18的齿部啮合。调速结构286可以调节驱动件282驱动转动件284转动的速度,进而调控平衡器20的移动速度。
具体地,第一级传动结构2862包括蜗杆28622和蜗轮28624。第二级传动结构2864包括第一齿轮28642和第二齿轮28644。蜗杆28622连接驱动件282的输出轴2822和蜗轮28624,蜗轮28624和第一齿轮28642固定连接,第一齿轮28642和第二齿轮28644啮合,第二齿轮28644连接转动件284。请参阅图13和图14,第二齿轮28644相背的两侧连接有传动轴2868,传动轴2868连接转动件284的两个齿轮2842,以实现同步转动。在驱动组件28工作的过程中,首先驱动件282通过输出轴2822带动蜗杆28622转动,接着蜗杆28622带动与其配合的蜗轮28624转动,实现第一级传动,进而蜗轮28624带动第一齿轮28642,而后第一齿轮28642带动第二齿轮28644,实现第二级传动。第二齿轮28644通过传动轴2868带动转动件284的两个齿轮2842同步转动,从而带动平衡器20在腔室12内移动。传动轴2868可为圆柱形轴或非圆柱形轴。在图示的实施方式中,传动轴2868为D型轴。
第一齿轮28642和第二齿轮28644的模数都为0.5,齿数比为1:3。此外,蜗轮28624和蜗杆28622还可起到限位的作用,在驱动件282不工作的情况下,平衡器20能稳定的保持在腔室12内。在一个例子中,两级传动可实现平衡器20减速比达到75以上。
请参阅图15,承载结构21包括承载板212和滚动件214。滚动件214能够转动地连接承载板212并与腔室12的内壁122接触,驱动组件28安装在承载板212上。
具体地,承载板212的两端设有两个滚动件214。滚动件214包括轴承2142和转轴2144。转轴2144与承载板212固定连接,固定连接的方式可为金属焊接的方式、粘合剂粘接的方式、由螺丝螺旋连接的方式或者卡扣卡接的方式进行连接,在此不作具体限定。转轴2144穿设轴承2142,轴承2142套设在转轴2144上。在驱动件282驱动转动件284带动平衡器20移动的过程中,轴承2142绕转轴2144转动,从而使承载结构21在腔室12内滑动。
进一步地,承载板212上还设有安装孔2122,安装孔2122用于将承载结构21与 驱动组件28安装连接。例如,可通过紧固件将承载结构21安装至箱体2866,使驱动组件28设于承载结构21上。安装孔2122可为圆形、矩形,椭圆形等。
请参阅图16,承载结构21可为具有一定弧度的弧形块,例如由POM等光滑材料制作的弧形块。在驱动件282驱动转动件284带动平衡器20移动的过程中,弧形块可在腔室12内滑动。
请参阅图12,腔室12内设有第二导向结构13。第二导向结构13与第一导向结构23连接以导引平衡器20的移动。如此,通过第一导向结构23和第二导向结构13的导引,使得平衡器20在高速移动的情况下,能够稳定地在腔室12内移动,避免平衡器20脱离平衡体10。
可以理解,在平衡器20高速移动的情况下,相关技术中很难保证平衡器20稳定移动,平衡器20可能会因为转速过快而脱离平衡体10。在本申请实施方式中,第一导向结构23与第二导向结构13弹性连接,可防止平衡器20在移动过程中晃动。第一导向结构23与第二导向结构13互相配合,共同导引平衡器20的移动,使得平衡器20可以在任何转速下,保持稳定移动。第一导向结构23的个数可为两个,两个第一导向结构23安装在平衡器20的两端。第一导向结构23可通过连接板安装在支架24的两端。在其他实施方式中,第一导向结构23的个数可以是其他,在此不做具体限定。
请参阅图12和图17-图19,第一导向结构23包括导向件232,导向件232包括导向轮2322,第二导向结构13包括导轨132,导向轮2322能够活动地连接导轨132。如此,有利于减小平衡器20在移动时第一导向结构23与第二导向结构13之间的摩擦力。
具体地,导向轮2322可与导轨132的侧面滑动地连接,或滚动地连接。在一个例子中,导向轮2322为滚轮,形状可为圆形,表面圆滑的导向轮2322可在导轨132上滚动移动。这样,在平衡器20移动过程中,第一导向结构23与第二导向结构13之间的摩擦力较少,减少了平衡器20移动时的阻力,有利于减少平衡器20的功率。在图17的示例中,每个第一导向结构23包括两个导向件232,对应地,导轨132的数量为两个。在图19的示例中,每个第一导向结构23包括一个导向件232,对应地,导轨132的数量为一个。
请参阅图17和图19,导向件232包括两个导向轮2322和连接杆2324,两个导向轮2322通过连接杆2324连接,导轨132部分地位于两个导向轮2322之间的空间。如此,使得导向件232的两个导向轮2322与能够夹持导轨132,更进一步地保证平衡器20的稳定移动。
具体地,导轨132包括相背的两侧面,导轨132的截面基本呈梯形。两个导向轮2322通过连接杆2324连接形成形状呈H型的导向件232。导向轮2322与导轨132的侧面可滑动地或滚动地连接。呈H型的导向件232可对导轨132进行夹持,更进一步地保证平衡器20的稳定移动。在图示的实施方式中,导向轮2322可在导轨132上滚动,两个导向轮2322可夹持导轨132。在其它的实施方式中,第一导向结构23和第二 导向结构13可通过嵌设、啮合的方式相互连接,也能起到导向作用。在此不对其他实施方式进行限定。
此外,两个导向轮2322可与连接杆2324转动连接,例如通过轴承连接。两个导向轮2322也可与连接杆2324固定连接。固定连接的方式可为金属焊接、螺丝连接或者卡扣卡接,在此不做具体限定。在图示的实施方式中,两个导向轮2322与连接杆2324固定连接,两个导向轮2322与连接杆2324一同转动。可以理解,在该实施方式中,第一导向结构23还包括连接架234和固定在连接架234的转轴236。转轴236固定不动,转轴236穿设两个导向轮2322和连接杆2324,两个导向轮2322和连接杆2324可共同绕着转轴236转动,即导向件232绕着转轴236转动。
请参阅图12,导向轮2322与导轨132弹性抵接。可以理解,导轨132部分地位于两个导向轮2322之间的空间,这一定的空间使得导向轮2322与导轨132能够存在弹性抵接的可能性,可防止平衡器20在移动过程中晃动,保证平衡器20的稳定移动。具体地,在导向件232与导轨132之间的作用力过大时,导向件232的导向轮2322与导轨132弹性抵接产生的作用力,使导向轮2322远离导轨132,对导向轮2322和导轨132之间的作用力进行缓冲。如此,可以减小第一导向结构23和第二导向结构13之间的作用力,防止平衡器20在移动过程中晃动。
进一步地,请参阅图17-图19,第一导向结构23包括底座238和连接架234。连接架234能够弹性移动地连接底座238,导向件232安装在连接架234。如此,在平衡器20移动的过程中,依靠连接架234能够弹性移动地连接底座238,实现导向轮2322与导轨132弹性抵接,使得平衡器20能稳定地移动。
具体地,底座238内设有弹性件231,弹性件231连接连接架234,弹性件231用于向连接架234提供一作用力以使导向轮2322与导轨132弹性抵接。如此,通过弹性件231提供的作用力,使得导向轮2322与导轨132能够弹性抵接,进而保证平衡器20在任何转速下都能够稳定地移动。
可以理解,底座238内开设有用于收容弹性件231的盲孔,连接架234的下方设有连接柱233,弹性件231的一端连接至连接柱233,弹性件231的另一端抵接至盲孔的底壁。弹性件231可通过连接柱233与连接架234连接。在图示的实施方式中,每个第一导向结构23包括两个弹性件231和两个连接柱233,弹性件231和连接柱233一一对应连接。第一导向结构23包括两个弹性件231,使得底座238可承受更大的作用力。在其他实施方式中,第一导向结构23的弹性件231的数量可以为1个、3个或其他个数,在这里不作具体限定。连接柱233的数量与弹性件231的数量一致。弹性件231可为弹簧,例如螺旋弹簧、钢板弹簧、扭杆弹簧、气体弹簧或橡胶弹簧等,在此不作具体限定。
请参阅图3、图6和图11,平衡组件100还包括安装在家用电器1000的腔体300的第一无线充电组件30和储能装置40,家用电器1000包括第二无线充电组件900。 第一无线充电组件30连接储能装置40。第一无线充电组件30用于接收由第二无线充电组件900无线发射的充电能量,并利用充电能量为储能装置40充电。储能装置40位于平衡器20外,设于腔室12的内壁122的第二导向结构13是能够导电的且电连接储能装置40,平衡器20的第一导向结构23也是能够导电的。由于第一导向结构23与第二导向结构13能够活动地连接,储能装置40通过导电的第一导向结构23和第二导向结构13向平衡器20供电。可以理解,储能装置40位于平衡器20外,可减少平衡器20自身的重量,使得平衡器20更容易被驱动,进一步地,在有多个平衡器20的情况下,多个平衡器20可共用储能装置40,平衡组件100可形成统一式的电源供应,成本较低。
具体地,第一无线充电组件30包括接收线圈32,第二无线充电组件900包括发射线圈910,接收线圈32和发射线圈910间隔相对设置。发射线圈910可向接收线圈32发射充电能量,接收线圈32利用接收到的充电能量为储能装置40充电。储能装置40电连接第二导向结构13,实现平衡器20经过第二导向结构13从储能装置40取电。
可以理解,在家用电器1000为洗衣机的情况下,接收线圈32可安装在腔体300的固定架700上,发射线圈910可安装在盛水腔体210的一端,接收线圈32和发射线圈910间隔相对设置。接收线圈32和发射线圈910的中心轴线与腔体300传动轴线X共线。如此,腔体300转动时,对接收线圈32和发射线圈910的电能传输效率影响较少。
在图11和图12的示例中,第一导向结构23包括能够导电的两个导向件232和两个转轴236,第二导向结构13包括能够导电的两个导轨132。导向件232套设转轴236,导向件232和导轨132一一对应连接。两个导向件232分别通过其套设的转轴236电连接控制板。如此,第一导向结构23通过第二导向结构13从储能装置40取电并将电能传输至控制板,控制板可向平衡器20的负载(如驱动件282)提供电能。
具体地,储能装置40可包括可充电电池,可充电电池的正极、负极分别通过导线237连接导轨132、导轨132连接导向件232,导向件232连接转轴236,转轴236通过导线237连接控制板。电池的电能由两个导轨132向平衡器20传输。由于两个导向件232分别连接两个导轨132,根据金属具有导电性的原理,导向件232可通过导轨132从电池取电,接着,导向件232将电能传递到转轴236和导线237,而后,输送到平衡器20的控制板,进而,控制板可向平衡器20的负载提供电能。转轴236可为铜轴,导向件232和导轨132可采用铜制成。转轴236、导向件232和导轨132也可采用其他导电材料制成,在此不作具体限制。
在图17的示例中,第一导向结构23包括底座238、两个弹性件231、两个连接架234和两个导向件232、两个弹性件231连接底座238且分别连接两个连接架234,两个导向件232分别安装在两个连接架234。导向件232的转轴236固定连接连接架234。两个连接架234内设有安装槽2342,安装槽2342供连接转轴236和控制板的导线237 穿过。在平衡器20移动的过程中,连接架234在弹性件231的作用下,使两个导向件232分别与两个导轨132紧密地连接。如此,可避免由于装配误差和制造误差导致的导向件232与导轨132接触不良的风险。
请参阅图7和图10,平衡器20还包括第一无线充电组件25和储能装置27,储能装置27连接第一无线充电组件25,家用电器1000包括第二无线充电组件900。第一无线充电组件25用于接收由家用电器1000的第二无线充电组件900无线发射的充电能量,并利用充电能量为储能装置27充电。如此,平衡器20的第一无线充电组件25可经由无线传输的方式接收充电能量,并为储能装置27充电,这样可避免采用电刷的方式来实现电传输,进而可以提高平衡体10的密封性以及输电的可靠性。而且,平衡器20自身上安装有第一无线充电组件25和储能装置27,这样,平衡器20可形成独立式的电源供应,不易受其它因素影响而断电。
可以理解,第二无线充电组件900设置在本体200,主控制器400连接第二无线充电组件900,可控制第二无线充电组件900发射充电能量。具体地,在储能装置27需要充电的情况下,主控制器400控制第二无线充电组件900发射激活信号,第一无线充电组件25接收到激活信号后向第二无线充电组件900发送充电信号,第二无线充电组件900接收到充电信号再发射充电能量,第一无线充电组件25利用接收到的充电能量为储能装置27充电。如此,实现无线充电的精确定位,可以避免第二无线充电组件900处于无接收端接收充电能量的持续运行状态下而导致损坏的问题。
在图10的示例中,储能装置27包括可充电电池。平衡器20包括电池仓29,电池仓29安装在支架24,电池容置在电池仓29。第一无线充电组件25包括第一线圈252,第一线圈252安装在电池仓29的外表面并与电池连接。第二无线充电组件900包括第二线圈(图未示)。在本实施方式中,第一线圈252可随平衡器20的移动而移动,第二线圈的位置固定,因此,第一线圈252和第二线圈所在平面相对设置。第一线圈252和第二线圈可以是电磁线圈。第二线圈可以发射电磁波能量,所发射的电磁波能量可以为第一线圈252提供电能,第一线圈252在接收到第二线圈所发射的电磁波能量后可以发送脉冲信号。因此,第二无线充电组件900发射激活信号,可以是第二无线充电组件900的第二线圈间歇性发射电磁波能量(即发射功率较低)或在预设时长内持续性发射电磁波能量,预设时长大于或等于平衡器20运动一周的时长。第一无线充电组件25发送充电信号,可以是第一无线充电组件25的第一线圈252发送脉冲信号。第二无线充电组件900、发射充电能量,可以是第二无线充电组件900、的第二线圈持续性发射电磁波能量(即发射功率较高)。
请参阅图20,平衡组件100包括标识件50和位移检测件60,平衡组件100被配置为驱动组件28驱动平衡器20在腔室12内移动的情况下,标识件50与位移检测件60发生相对运动,位移检测件60用于检测标识件50经过位移检测件60的次数,标识件50经过位移检测件60的次数与平衡器20的位置相关。如此,位移检测件60可检 测标识件50经过位移检测件60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,本申请实施方式中,在平衡器20在腔室12内移动的情况下,标识件50与位移检测件60发生相对运动而经过位移检测件60,而标识件50经过位移检测件60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50经过位移检测件60的次数来确定平衡器20的移动距离,再结合平衡器20的初始位置121可以确定平衡器20的位置。初始位置121可以指平衡器20在腔室12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,转动件284设有标识件50,或腔室12的内壁122设有标识件50。如此,可提供多种对标识件50的检测方式,提高了标识件50在安装时的灵活性。在图示的实施方式中,转动件284设有标识件50。可以理解,转动件284包括齿轮2842。腔室12包括内壁122,内壁122设置有连接件18。齿轮2842与连接件18的齿部啮合。标识件50为齿轮2842的齿。如此,可利用齿轮2842的齿作为标识件50,无需另外设置标识件50。可以理解,在其它实施方式中,标识件50也可为连接件18的齿部的齿。
齿轮2842或连接件18的齿部的齿之间具有凹槽,齿与凹槽均匀交错分布。齿轮2842与连接件18的齿部啮合转动,在齿轮2842转动的情况下,可带动平衡器20相对于连接件18移动。在这种情况下,齿轮2842的齿或连接件18齿部的齿可作为标识件50,对应地,位移检测件60可安装于平衡器20。位移检测件60包括检测面,检测面朝向标识件50。以齿轮2842的齿作为标识件50,即转动件284设有标识件50。以设置于内壁122的连接件18齿部的齿作为标识件50,即腔室12的内壁122设有标识件50。在其他实施方式中,标识件50可设置在腔室12内除内壁122以外的位置。
具体地,当标识件50为齿轮2842的齿时,位移检测件60可以安装在平衡器20上正对着齿轮2842的齿的位置。齿轮2842转动时,位移检测件60相对不动。当标识件50为连接件18齿部的齿时,位移检测件60可以安装在平衡器20上正对着连接件18齿部的齿的位置,齿轮2842转动时,平衡器20移动进而带动位移检测件60相对于连接件18移动。在齿轮2842转动的过程中,齿轮2842的齿会不断经过位移检测件60,因此,可以检测齿轮2842的齿经过位移检测件60的次数,即齿轮2842经过位移检测件60的齿数。
位移检测件60包括光传感器、霍尔传感器、超声波传感器的至少一种。如此,位移检测件60具有可选择性,而且成本也较低。具体地,当位移检测件60包括一个种类的传感器时,可以选择光传感器、霍尔传感器、超声波传感器的其中一种。当位移检测件60包括多个种类的传感器时,可以选择光传感器、霍尔传感器、超声波传感器的两种或两种以上。两个或两个以上的传感器所检测到的数据可取平均值作为位移检测件60的输出数据,也可以将数据进行不同权重或比例的计算来作为位移检测件60的输出数据。
在图21的示例中,标识件50为齿轮2842的齿28422,位移检测件60为光传感器。光传感器可发射和接收光信号。由于齿轮2842的齿28422和凹槽28424与光传感器的距离不同,光传感器接收到齿28422反射回来的光信号强度与凹槽28424反射回来的光信号强度不同,经过处理可以得到有规律的脉冲信号,脉冲的数量即齿轮2842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的初始位置121可以得到平衡器20的位置。光传感器可为红外传感器。超声波传感器与光传感器的原理类似,在此不再赘述。
在图22的示例中,标识件50为齿轮2842的齿28422,位移检测件60为霍尔传感器。由于齿28422与凹槽28424会影响霍尔传感器的磁力线的方向,从而改变通过霍尔传感器的磁力线密度。当齿轮2842转动时,霍尔传感器会输出有规律的脉冲信号,根据脉冲信号可以计算得到齿轮2842的转动的齿数,由此可以得到平衡器20的移动距离,再结合平衡器20的初始位置121可以得到平衡器20的位置。
在其它的实施方式中,标识件50可为黑白相间的条纹,位移检测件60可为光传感器。黑白相间的条纹可以设置在齿轮2842上,或设在与齿轮2842同轴转动的部件上、或设置在腔室12的内壁122形成圆环并与连接件18同心设置,光传感器可以安装在平衡器20上正对黑白相间的条纹的位置。由于黑条纹吸收光,白条纹反射光,在平衡器20移动的过程中,黑白相间的条纹会不断经过光传感器,因此,可以检测白条纹经过光传感器的次数,即经过光传感器的白条纹数量。根据光传感器接收到的光信号可以得到有规律的脉冲信号,脉冲的数量即平衡器20转动经过白条纹的数量。由于白条纹与黑条纹的宽度确定,由此可以得到平衡器20的移动距离,再结合平衡器20的初始位置121可以得到平衡器20的位置。
需要指出的是,上述标识件50还可以具有其它结构,例如,转动件284可为轮子,轮子具有间隔的多个幅条,标识件50可为轮子的幅条。位移检测件60可检测幅条经过位移检测件60的次数。具体的检测原理与上述的检测原理类似。
请参阅图6、图7和图23,腔室12设有初始位置121。平衡器20包括控制器22,控制器22电连接位移检测件60。控制器22用于根据标识件50经过位移检测件60的次数和初始位置121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的初始位置121指平衡器20静止在腔室12内时的默认位置。控制器22记录有初始位置121,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60根据标识件50经过位移检测件60的次数可输出有规律的脉冲信号,控制器22接收位移检测件60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的初始位置121,最终可计算得到平衡器20的具体位置。平衡器20的具体位置可通过有线或无线的方式发送到家用电器1000的主控制器400。
在本申请实施方式中,腔室12内可设有多个初始位置121。在腔室12内有多个平衡器20的情况下,每个初始位置121均停留有一个平衡器20。在一个实施方式中,腔室12内设有两个初始位置121,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,每个初始位置121均静止地停留有一个平衡器20。较佳地,两个初始位置121成度对称布置。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。在其他实施方式中,初始位置121的数量可以是一个、三个或其他数量,具体位置可根据需要设置,在此不作具体限定。
请参阅图20和图24,平衡组件100包括校正件70和校正检测件80。平衡组件100被配置为在平衡器20移动的情况下,校正件70与校正检测件80发生相对移动,校正检测件80用于检测校正件70以消除平衡器20的位置误差。如此,提高了对平衡器20的移动距离的计算精度。
可以理解,由于平衡器20长时间移动,位移检测件60检测标识件50经过位移检测件60的次数信息时可能会出现累计的误差。因此,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70和校正检测件80来消除平衡器20的位置误差。
具体地,当校正检测件80经过每一个校正件70时,其检测到校正件70的信息会传输到控制器22。进一步地,控制器22会将平衡器20所处的该位置设定为0值,即视为原点重新计算平衡器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80经过每一个校正件70后,位移检测件60对标识件50所经过的次数信息会被通过脉冲信号的方式从0开始再次反馈到控制器22,控制器22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24,校正件70分布有多个,间隔设置在腔室12的内壁122,每个校正件70包括不同数量的校正部。校正检测件80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80经过不同数量的校正部会触发不同的脉冲信号,脉冲信号的脉冲个数与校正部的数量相同,从而可以根据校正检测件80输出的脉冲信号确定平衡器20正经过某个校正件70,从而确定平衡器20在腔室12内的具体位置。如此,可以在腔室12内定位平衡器20的位置。在一个例子中,腔室12的内壁122每隔90度设置有一个校正件70,校正部的数量分别为一个、两个、三个、四个。校正件70的数量和位置及校正件70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。光传感器、超声波传感器或霍尔传感器检测校正件70的原理与检测标识件50的原理相同,在此不再赘述。
综上,本申请实施方式的一种平衡组件200用于家用电器1000。平衡组件100包括平衡体10和平衡器20。平衡体10用于安装在家用电器1000的腔体300。平衡体10内设有腔室12,平衡器20包括承载结构21和驱动组件28,驱动组件28设在承载结 构21上。驱动组件28用于驱动平衡器20在腔室12内移动,承载结构28与腔室12的内壁122接触并用于在平衡器20移动的过程中,沿着腔室12的内壁122运动以承担平衡器20在腔室12内运动时所受到的离心力作用。
上述实施方式的平衡组件100中,承载结构21可承担由于腔体300高速转动而产生的离心力作用,避免了平衡器20所受到的离心力增大驱动组件28与平衡体10的摩擦力,承载结构21的设置能够使得驱动组件28较容易驱动平衡器20在腔室12内移动。
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。
