技术领域
本申请涉及家用电器技术领域，具体而言，涉及一种喷臂组件及具有其的洗涤电器。
背景技术
目前，因其便利性，洗涤电器，如洗碗机受到越来越多用户的使用。一般来说，用户对洗涤电器洗净的需求是排在首位的。而影响洗涤电器洗净的一个因素是洗涤电器的喷臂。在洗涤电器工作时，喷臂旋转将洗涤液高速喷射至餐具来达到清洗餐具的目的。在相关技术中，喷臂与喷臂座连接的主要方式是通过卡接凸缘与卡扣配合连接，但是这种连接方式会导致喷臂与喷臂座之间的间隙较大，当喷臂工作时，喷臂中的水容易通过该缝隙泄露，影响清洗效果。此外，当喷臂与喷臂座产生相对运动时，二者之间的摩擦方式是滑动摩擦，因此损失的水动力比较大。另一方面，卡扣连接方式直接导致喷臂座和喷臂的上下高度尺寸较大，这样浪费了洗涤电器的内胆空间，减少了洗涤电器内部待清洗件的摆放空间。

下面结合图1-图12详细描述根据本申请实施例的喷臂组件1000。喷臂组件1000可用于洗涤电器10000中，下面以将喷臂组件1000应用于洗碗机为例来说明喷臂组件1000的结构。参照图1-图3所示，根据本申请实施例的喷臂组件1000可以包括：喷臂100、喷臂座200与滚珠330。
喷臂100与喷臂座200相连，且喷臂100相对于喷臂座200可转动，滚珠330设置在喷臂100与喷臂座200的连接配合处，通过设置喷臂座200，为喷臂100提供了连接接口，同时，喷臂100与喷臂座200连接为一体后，喷臂座200还可以充当喷臂100的进水管路，当洗碗机的水源接通后，水流从喷臂座200流入到喷臂100中。在一些实施例中，喷臂100上设置有喷水孔和驱动孔，当喷臂100内的水压达到一定值后，喷臂100开始通过喷水孔和驱动孔喷出水柱，喷臂100受到水柱喷出时的反作用力而转动，随着水柱不断地从喷水孔和驱动孔中喷出，喷臂100可持续地转动，从喷水孔和驱动孔喷出的水柱随着喷臂100 的转动会洒向餐具表面或洗碗机内壁，进而将餐具或洗碗机内壁的污渍洗净，从而完成洗碗机对餐具的清洗工作。喷臂100喷射到餐具上的水柱方向和位置是多向的，减少了死角更容易洗净，由于水流的覆盖率较大，清洗时间也会相应减少，即有利于缩短清洗时间。
首先结合图1-图6详细描述根据本申请实施例的喷臂组件1000。
参照图1-图3所示，喷臂组件1000还可以包括：承载基体，承载基体与滚珠330组成滚珠组件300，换言之，滚珠组件300包括：承载基体和滚珠330，滚珠组件300设置在喷臂100与喷臂座200的连接配合处，滚珠330可转动地设置在承载基体上。
在图1-图3所示的实施例中，承载基体包括：中间套筒310、内套筒320，内套筒320套设在中间套筒310的内部，滚珠330与喷臂100的内表面滚动接触，滚珠330与内套筒320的外表面滚动接触，喷臂座200的一部分设置在内套筒320的内部，且内套筒320与喷臂座200固定连接，因此，喷臂100与喷臂座200之间通过滚珠组件300实现间接连接，喷臂100、喷臂座200与滚珠组件300三者连接的结构简单、稳定。
当喷臂100相对于喷臂座200转动时，滚珠330发生滚动，从而使喷臂100与内套筒320发生相对转动，又因为喷臂座200与内套筒320固定，由此实现喷臂100与喷臂座200的相对转动。
通过设置滚珠组件300，当喷臂100相对于喷臂座200转动时，喷臂100与喷臂座200之间的摩擦形式为滚动摩擦，不再是之前的滑动摩擦，这样保证了喷臂100相对于喷臂座200转动时的摩擦力较小，即滚动摩擦力对喷臂100转动时的阻力很小，因此可以减少由于摩擦造成的水动力损失，提高水动力的利用率。同时，喷臂100相对于喷臂座200转动时的速度较快，所以通过设置滚珠组件300，有利于提高喷臂100转动时的平顺性，从而有利于降低洗碗机的噪声。
此外，滚珠组件300设置在喷臂100与喷臂座200之间，将喷臂100与喷臂座200巧妙地连接为一体，相比于原来喷臂100与喷臂座200单独通过卡扣连接的形式，可有效降低喷臂座200和喷臂100连接处的高度，从而减小了喷臂组件1000的高度尺寸，节省了洗碗机内部空间，为餐具的摆放留出了更多的空间，进而提升了洗碗机的餐具容量，例如可以增加洗碗机内部装载量10mm-40mm。
如图5所示，中间套筒310上设置有多个滚珠孔311，滚珠330可转动地安装在滚珠孔311里，滚珠孔311为滚珠330的固定提供了支撑，保证多个滚珠330的相对位置不变，防止多个滚珠330之间发生碰撞、挤压，由此可以提高滚珠组件300的工作稳定性，从而可以进一步提高喷臂100转动时的平顺性。可选地，滚珠330的数量与滚珠孔311的数量相同。
在具体实施例中，滚珠330的数量为多个，且多个滚珠330可沿中间套筒310的周向 均匀分布，由此可以提高喷臂100转动时的平稳性。优选地，滚珠330的数量为偶数，由此可以保证滚珠组件300受力均衡，缓解应力集中现象。
可选地，滚珠330的直径为3mm-8mm，滚珠330的数量为4个-12个。滚珠330可以是塑料滚珠或不锈钢滚珠，因为喷臂组件1000的工作环境充满了水，喷臂组件1000长期处于湿热环境，易导致滚珠330生锈卡滞，塑料滚珠或不锈钢滚珠的防腐蚀能力较强，可以有效减缓甚至避免滚珠330生锈。
如图1-3所示，滚珠330在中间套筒310的径向上突出中间套筒310的内周面和外周面，也就是说，滚珠330的直径大于中间套筒310的壁厚，滚珠330有且仅有中间部分是安装在中间套筒310内的，滚珠330的内侧向内凸出中间套筒310的内周面，滚珠330的外侧向外凸出中间套筒310的外周面，滚珠330与喷臂100、内套筒320之间均为滚动接触，又由于内套筒320与喷臂座200固定连接，因此相当于滚珠330与喷臂座200之间也为滚动接触，滚珠组件300为喷臂100以及喷臂座200的连接提供了支撑。当喷臂100与喷臂座200发生相对转动时，喷臂100与内套筒320之间通过滚珠330接触，因此喷臂100与内套筒320之间为滚动摩擦。
根据本申请实施例的喷臂组件1000，通过设置喷臂座200，为喷臂100提供了连接接口，同时喷臂座200还充当喷臂100的进水管路，通过在喷臂100与喷臂座200之间设置滚珠组件300，使喷臂100与内套筒320之间为滚动接触，而喷臂座200又与内套筒320固定，由此可以减小喷臂100与喷臂座200之间的摩擦力，从而有利于减小水动力损失，提高水动力的利用率，保证水从喷臂100喷水孔喷出的压力较大，有利于提升洗碗机对餐具的清洗效果，同时，喷臂100与喷臂座200之间通过滚珠组件300连接，可有效降低喷臂100进水口的高度，从而节省洗碗机内部空间。
参考图4所示，喷臂100可以包括：喷臂本体110和喷臂连接套120，喷臂连接套120设置在喷臂本体110的下侧，通过设置喷臂连接套120，方便了喷臂100与喷臂座200连接，保证了喷臂100与喷臂座200可以可靠地连接为一体。
如图2所示，喷臂连接套120与喷臂本体110内具有连通的喷臂腔室130，喷臂座200内具有与喷臂腔室130连通的喷臂座腔室240，由此可以保证洗碗机水源的水经喷臂座腔室240可以顺利地进入喷臂腔室130内，进而水经喷臂100上的喷水孔和驱动孔喷射到餐具表面，从而完成清洗餐具的操作。随着水持续地进入到喷臂腔室130，喷臂腔室130内的水压越来越高，此时从喷臂100驱动孔喷出的水柱所产生的反作用力也越大，喷臂100转动的速度也就越快，同时，喷出的水柱拍打在餐具上的力也越大，有利于清洗餐具上的污渍，因此通过设置喷臂腔室130，可以保证洗碗机的洗涤效果较好。
喷臂100与喷臂座200之间采用滚珠组件300连接之后，可以减小喷臂连接套120的 高度尺寸，从而减小了喷臂组件1000的整体高度尺寸，为餐具的摆放留出了更多的空间。
进一步地，喷臂连接套120的内周面上设置有适于与滚珠330配合的喷臂滚珠槽140，内套筒320的外周面上设置有适于与滚珠330配合的内套筒滚珠槽340，喷臂滚珠槽140、内套筒滚珠槽340均为周向环形槽，由此可以保证喷臂100整圈转动的顺畅性。滚珠330与喷臂滚珠槽140、内套筒滚珠槽340之间为滚动接触，摩擦力较小。在具体实施例中，喷臂滚珠槽140、内套筒滚珠槽340的直径可以与滚珠330的直径相等，或者也可以略大于滚珠330的直径，由此可保证滚珠330与喷臂滚珠槽140、内套筒滚珠槽340配合良好。
进一步地，在喷臂连接套120的中心轴线方向上，喷臂滚珠槽140、内套筒滚珠槽340、滚珠孔311的位置相对应，滚珠330部分地设置在滚珠孔311中，参照图2-图3所示，滚珠330的外侧与喷臂滚珠槽140接触，滚珠330的内侧与内套筒滚珠槽340接触，从而完成喷臂100与内套筒320的连接，内套筒320与喷臂座200固定连接，进而完成喷臂100与喷臂座200的间接连接。喷臂滚珠槽140、内套筒滚珠槽340、滚珠孔311的位置相对应，可以防止喷臂100转动时，滚珠330所滑动的轨迹与喷臂滚珠槽140以及内套筒滚珠槽340的轨迹不同，从而受到挤压，导致喷臂100无法转动。
具体地，喷臂座200可以包括：喷臂座本体210和喷臂座凸缘220，参考图2-图3所示，喷臂座凸缘220设置在喷臂座本体210的下方，且喷臂座凸缘220沿喷臂座本体210的径向向外延伸，喷臂座凸缘220的外径大于喷臂座本体210的外径，喷臂座凸缘220适于与洗碗机内的其它零部件相连，喷臂座凸缘220的外径较大，由此可使喷臂座200与其它零部件之间的固定更加稳定、可靠。
在一些实施例中，喷臂座200与承载基体之间可以是可拆卸连接。
如图3所示，滚珠组件300设置在喷臂座凸缘220的上方，喷臂座本体210上具有喷臂座卡扣230，喷臂座卡扣230适于卡在内套筒320的顶端，通过在喷臂座本体210上设置喷臂座卡扣230，可以保证喷臂座200与内套筒320可靠地连接为一体，并且方便喷臂座200与滚珠组件300进行连接与脱离，便于喷臂组件1000的安装。
喷臂座本体210的顶端具有多个凹槽，凹槽的开口方向与喷臂座本体210的轴线方向平行，喷臂座卡扣230从凹槽的底壁向上延伸，且喷臂座卡扣230的两侧与凹槽的两个侧壁分离开，由此保证喷臂座卡扣230可以在凹槽内发生弹性变形。喷臂座卡扣230的顶端设置有朝向内套筒320的卡勾，卡勾适于勾在内套筒320的顶端，从而限制喷臂座200与内套筒320的相对轴向位置。
在将内套筒320与喷臂座200装配时，内套筒320的内周面挤压喷臂座卡扣230的卡勾，使喷臂座卡扣230向喷臂座本体210的内部变形，保证喷臂座卡扣230可从内套筒320的底端到达内套筒320的顶端(即从下而上)，当喷臂座卡扣230越过内套筒320的顶端时， 喷臂座卡扣230所受的挤压力消失，在喷臂座卡扣230自身弹力的作用下，喷臂座卡扣230向内套筒320靠近，使得卡勾勾住内套筒320的顶端。
当需要将内套筒320与喷臂座200分离时，只需用力向上提起喷臂100，内套筒320顶端挤压卡勾，使得卡勾收回在内套筒320内部，继续提起喷臂100，便可将内套筒320与喷臂座200分离。
喷臂座本体210上边缘处的喷臂座卡扣230数量可以是多个(例如四个)，凹槽与喷臂座卡扣230一一对应，且多个喷臂座卡扣230沿喷臂座本体210的周向均匀布置，由此可以提高喷臂座卡扣230与内套筒320的卡接稳定性。
进一步地，喷臂连接套120、中间套筒310、内套筒320的下表面与喷臂座凸缘220的上表面之间的间隙为L1，L1满足关系式：0mm＜L1≤1mm，例如，L1可以是0.3mm、0.5mm或0.8mm，也就是说，在喷臂座凸缘220的上表面与喷臂连接套120的下表面之间、喷臂座凸缘220的上表面与中间套筒310的下表面之间以及喷臂座凸缘220的上表面与内套筒320的下表面之间均有间隙，由此，在喷臂100与喷臂座200发生相对转动时，可以避免喷臂连接套120的底部与喷臂座凸缘220的上表面之间、中间套筒310的底部与喷臂座凸缘220的上表面、内套筒320的底部与喷臂座凸缘220的上表面之间接触而发生滑动摩擦，从而保证在喷臂100、喷臂座200之间除了与滚珠组件300中的滚珠330有滚动接触之外，无其他滑动接触。
通过设置间隙，可以保证喷臂100转动时具有较高的速度，并且平稳性较好，此外，通过将间隙设置为0mm-1mm，可以防止残羹剩饭或者其他污染物进入间隙中而增加喷臂100与喷臂座200之间的摩擦力甚至卡死喷臂100，并且当喷臂100倾斜时，喷臂100可快速与喷臂座200接触，从而避免喷臂100进一步倾斜。
参照图4所示，滚珠孔311设置在中间套筒310的顶部，滚珠孔311为优弧孔，且滚珠孔311的顶部缺口处形成滚珠取放口，滚珠330经滚珠取放口进入滚珠孔311或从滚珠孔311出来，由此方便了滚珠330在滚珠孔311内的安装与拆卸。优弧孔是圆心角大于180°且小于360°的孔，由此可以使每个滚珠330的大部分位于滚珠孔311内，防止安装完成后，滚珠330从滚珠孔311内脱落。在安装滚珠330时，可以借助外力将滚珠取放口撑开，随后将滚珠330经滚珠取放口安装在滚珠孔311内，接着撤去外力，滚珠孔311的弹性变形随之消失，滚珠孔311恢复原状，此时滚珠孔311紧紧包裹滚珠330，使得滚珠330在滚珠孔311内的安装更加牢固、可靠。
进一步地，相邻的两个滚珠孔311之间设置有弱化槽342，通过设置弱化槽342，可使相邻的两个滚珠孔311之间的刚度较小，由此在安装滚珠330时，滚珠孔311容易变形，从而减小了滚珠330的安装或拆卸难度。
进一步地，弱化槽342内设置有弱化槽立柱341，可选地，弱化槽342立柱的中心轴线与中间套筒310的中心轴线平行，由此有利于简化中间套筒310的加工工艺。通过设置弱化槽立柱341，可以起到一定的强化作用，从而防止弱化槽342过度削弱中间套筒310的刚度，进而有利于提高滚珠组件300的工作可靠性。
在一些未示出的实施例中，滚珠孔311设置在中间套筒310的底部，滚珠孔311为优弧孔，且滚珠孔311的底部缺口处形成滚珠取放口。
在另一些未示出的实施例中，滚珠孔311还可以设置在中间套筒310的中部，此时滚珠孔311为完整的孔。
中间套筒310的作用主要有三点：(1)通过在中间套筒310上开设滚珠孔311，并将滚珠330安装在滚珠孔311内，可以固定、限位滚珠330的位置，防止滚珠330堆积；(2)起到隔离食物残渣的作用，防止食物小残渣进入滚珠槽，而造成摩擦；(3)起到强化作用，又能隔离喷臂100震动，防止喷臂100晃动严重。
喷臂座200与承载基体之间的可拆卸连接方式除了上述的卡接形式之外，还可以通过螺纹连接。具体而言，承载基体具有基体螺纹，喷臂座200具有喷臂座螺纹，喷臂座螺纹与基体螺纹螺接配合，以此实现喷臂座200与承载基体的连接，当旋松喷臂座螺纹与基体螺纹时，可实现喷臂座200与承载基体的拆卸。
基于图3，臂座200与内套筒320的可拆卸连接可以具有多种变形方式，这些变形方式都落入本申请的保护范围内。
例如，在其中第一个未示出的实施例中，喷臂座200包括：喷臂座本体210，喷臂座螺纹为设置在喷臂座本体210的外周面上的喷臂座外螺纹，基体螺纹为设置在内套筒320的内周面上的内套筒内螺纹。即相比上述图3的实施例而言，喷臂座200与内套筒320之间为螺纹连接，喷臂座外螺纹与内套筒内螺纹螺接配合，可实现喷臂座200与内套筒320的可拆卸连接。
又例如，在其中第二个未示出的实施例中，喷臂座200包括：喷臂座本体210，相比上述图3的实施例而言，内套筒320向下超出中间套筒310，基体螺纹为设置在内套筒320的外周面上的内套筒外螺纹，喷臂座本体210套设在内套筒320向下超出中间套筒310部分的外侧，喷臂座螺纹为设置在喷臂座本体210的内周面上的喷臂座内螺纹，喷臂座本体210的内周面与内套筒320的外周面配合。喷臂座内螺纹与内套筒外螺纹螺接配合，可实现喷臂座200与内套筒320的可拆卸连接。
基于图1-图3的实施例，本申请的承载基体可以具有多种变形方式，这些变形方式都落入本申请的保护范围内。下面结合图1-图3、图6对根据本申请实施例的承载基体的多个变型例进行概述。
例如，在其中一个未示出的实施例中，承载基体可以仅包括：内套筒320，即相比上述图3的实施例而言，减少了中间套筒310，此时，滚珠330与内套筒320外周面的内套筒滚珠槽340滚动接触，又与喷臂连接套120内周面的喷臂滚珠槽140滚动接触，由此实现喷臂100与喷臂座200的滚动连接。
例如，在图6示出的实施例中，承载基体可以包括：内套筒320、中间套筒310、外套筒350，外套筒350套设在中间套筒310的外侧，外套筒350的内周面上设置有适于与滚珠330配合的外套筒滚珠槽，内套筒320的外周面上设置有适于与滚珠330配合的内套筒滚珠槽340。喷臂连接套120的内周面与外套筒350的外周面之间为过盈配合，由此可防止滚珠组件300从喷臂连接套120内脱落。此时，滚珠330与内套筒320外周面的内套筒滚珠槽340滚动接触，又与外套筒350内周面的外套筒滚珠槽滚动接触，由此实现喷臂100与喷臂座200的滚动连接。
例如，在另一个未示出的实施例中，承载基体可以包括：内套筒320、外套筒350，即相比上述图6的实施例而言，减少了中间套筒310，外套筒350套设在内套筒320的外侧，外套筒350的内周面上设置有适于与滚珠330配合的外套筒滚珠槽，内套筒320的外周面上设置有适于与滚珠330配合的内套筒滚珠槽340。喷臂连接套120的内周面与外套筒350的外周面之间为过盈配合，由此可防止滚珠组件300从喷臂连接套120内脱落。此时，滚珠330与内套筒320外周面的内套筒滚珠槽340滚动接触，又与外套筒350内周面的外套筒滚珠槽滚动接触，由此实现喷臂100与喷臂座200的滚动连接。此时，滚珠组件300为一独立的模块化部件，安装拆卸方便，也减少了喷臂座200或喷臂100的加工工艺成本。
下面结合图7-图12详细描述根据本申请实施例的喷臂组件1000。
请结合图7至图12，本申请实施方式的喷臂组件1000可以用于洗涤电器10000，喷臂组件1000包括喷臂100和喷臂座200，喷臂座200包括安装部122，安装部122开设有安装空间1222，喷臂100设置有进水轴112，进水轴112至少部分地安装在安装空间1222中，滚珠330设置在进水轴112位于安装空间1222的外侧面和安装部122的内侧面之间，滚珠330能够滚动地连接进水轴112和安装部122。
本申请实施方式的喷臂组件1000中，水流可以从喷臂座200经进水轴112流到喷臂100中，且水流从喷臂100内向外喷射可以推动喷臂100旋转，在喷臂100旋转时，滚珠330能够实现喷臂100和喷臂座200的滚动摩擦，使得喷臂100与喷臂座200间的摩擦力是滚动摩擦力，如此，减少了驱动喷臂100旋转的动力损失，提高了驱动喷臂100旋转的动力的利用率，使得水从喷臂100喷孔喷出后压力更大，利于增加喷臂组件1000的洗净效果。
具体地，在某些实施方式中，滚珠330的直径为3mm-8mm。滚珠330可为钢珠或塑料珠， 滚珠330的表面可涂有润滑材料，以减少喷臂100和喷臂座200的滚动摩擦力，进一步提高喷臂100的动力的利用率。
请结合参阅图8和图10，在某些实施方式中，进水轴112的外侧面沿进水轴112的周向开设有第一滚珠槽1122，滚珠330部分地容置在第一滚珠槽1122。
如此，滚珠330部分地位于第一滚珠槽1122可以保持滚珠330和进水轴112配合的稳定性，滚珠330不容易脱出，同时，可以在一定程度上限制喷臂100沿进水轴112的轴线X方向的位移，有利于提高喷臂组件1000的可靠性。
具体地，第一滚珠槽1122沿进水轴112的外侧面呈一圈环状的凹槽，第一滚珠槽1122的内壁呈圆弧状。如此，滚珠330和第一滚珠槽1122内壁配合，喷臂100可以平稳地绕进水轴112的轴线X旋转。
在某些实施方式中，喷臂组件1000包括第一连接轴14，第一连接轴14容置于安装空间1222，第一连接轴14位于进水轴112的外侧面和安装部122的内侧面之间，第一连接轴14开设有第一轴通孔142，进水轴112穿设第一轴通孔142，第一连接轴14的上端开设有滚珠孔311，滚珠330部分地容置在滚珠孔311。
如此，滚珠孔311可以进一步限定滚珠330的位置，喷臂组件1000的装配时，先将滚珠330装到第一连接轴14，再将带有滚珠330的第一连接轴14安装到进水轴112的外侧面和安装部122的内侧面之间，有利于喷臂组件1000的装配。
在某些实施方式中，滚珠孔311的中心与第一滚珠槽1122的中心水平对齐。如此，滚珠孔311限制滚珠330位置的同时，滚珠330和进水轴112可接触地发生滚动摩擦。
在某些实施方式中，滚珠330的数量是多个，滚珠孔311的数量是多个，滚珠330和滚珠孔311一一对应，多个滚珠330沿第一连接轴14的周向均匀分布。如此，多个滚珠330有利于增加喷臂100旋转的稳定性。
具体地，在某些实施例中，多个滚珠330的数量是偶数。多个滚珠孔关于第一连接轴14的轴线对称分布，使得多个滚珠330关于第一连接轴14的轴线对称分布。如此，喷臂100旋转时，可以保证产生滚动摩擦的部位受力均匀，有利于增加喷臂组件1000的可靠性。在本申请实施方式中，第一连接轴14的轴线与进水轴112的轴线X重合。
进一步地，在一个例子中，滚珠330的数量是4-12个。
当然，在其他实施方式中，滚珠330的数量和滚珠孔311的数量可以不限于上述讨论的实施方式，而可以根据需要灵活配置。
在某些实施方式中，第一连接轴14的上端在滚珠孔311的上部形成有缺口146。如此，将滚珠330安装到第一连接轴14时，可以通过挤压滚珠330使得滚珠孔311发生轻微形变，从而滚珠330可以稳定安装到滚珠孔311的位置，第一连接轴14可以同时将多个滚珠330 安装至进水轴112的外侧面和安装部122的内侧面之间，便于喷臂组件1000的装配。且第一连接轴14安装到进水轴112的外侧面和安装部122的内侧面之间时，滚珠330与进水轴112的外侧面、安装部122的内侧面配合从而滚珠330可以恢复滚动。
在某些实施方式中，喷臂组件1000包括第二连接轴15，第二连接轴15至少部分地容置在安装空间1222中，第二连接轴15与安装部122连接，第二连接轴15开设有第二轴通孔152，进水轴112穿设第二轴通孔152，滚珠330能够滚动地连接进水轴112的外侧面和第二连接轴15的内侧面。
如此，进水轴112可以相对第二连接轴15旋转，进水轴112和第二连接轴15可以与滚珠330实现滚动摩擦。可以理解，喷臂座200通常固定安装在腔体20，喷臂组件1000装配时，先将喷臂100、第二连接轴15和滚珠330组装完成，由于喷臂100可以相对第二连接轴15旋转，这样，可以先对喷臂100的旋转效果进行测试，测试完成后再通过第二连接轴15固定连接到喷臂座200，增加了第二连接轴15可以使得喷臂100在安装到喷臂座200之前进行旋转效果的测试，有利于喷臂100旋转的调试和喷臂组件1000的装配。
在一个实施方式中，第二连接轴15与安装部122固定连接。在另外的实施方式中，第二连接轴15也可相对转动地连接安装部122，第二连接轴15与安装部122之间也可以是滚动的方式连接。
在某些实施方式中，第二连接轴15的内侧面沿第二连接轴15的周向开设有第二滚珠槽154，滚珠330部分地容置在第二滚珠槽154。
如此，第二滚珠槽154可以限定滚珠330的位置，在一定程度上限制了喷臂100在进水轴112的轴线X方向上的位移，使得滚珠330与第二连接轴15、进水轴112的配合更加稳定。
具体地，第二滚珠槽154沿第二连接轴15的内侧面呈一圈环状的凹槽，第二滚珠槽154的内壁呈圆弧状。如此，滚珠330和第二滚珠槽154内壁配合，使得喷臂100可以平稳地绕进水轴112的轴线X旋转。
进一步地，在本申请图示的实施方式中，进水轴112开设有第一滚珠槽1122和第二连接轴15开设有第二滚珠槽154，第一滚珠槽1122和第二滚珠槽154位于滚珠相背的两侧，这样，第一滚珠槽1122和第二滚珠槽154能够共同限定滚珠在进水轴112的外侧面和第二连接轴15之间的位置，使得喷臂100旋转时更平稳。
较佳地，第一滚珠槽1122和第二滚珠槽154水平对齐。如此，滚珠330与第一滚珠槽1122、第二滚珠槽154的配合更加稳定。
在图示的实施例中，第一滚珠槽1122和第二滚珠槽154的数量均为一个。在其他实施例中，第一滚珠槽1122和第二滚珠槽154的数量可以不限于一个，例如，可以沿进水轴 112的轴线X的方向在进水轴112的外侧面形成多个第一滚珠槽1122，相应地，可以沿第二连接轴15的轴线方向在第二连接轴15的内侧面形成多个第二滚珠槽154，多个第一滚珠槽1122和多个第二滚珠槽154一一对应，滚珠330位于多个第一滚珠槽1122和多个第二滚珠槽154之间。如此，可以增加喷臂100连接的稳定性，喷臂100旋转时更平稳，有利于提高喷臂组件1000的可靠性。
在某些实施方式中，第二连接轴15的上端形成有向第二连接轴15的轴线凸设的凸缘156，凸缘156部分地遮挡滚珠330。
如此，凸缘156可以遮挡滚珠330使得滚珠330更好地容置在第二连接轴15与进水轴之间。
具体地，凸缘156在第二连接轴15上端形成的第二轴通孔152的孔径与进水轴112的外径相适应，使得进水轴112可以至少部分地容置在第二轴通孔152，凸缘156和滚珠330配合使得进水轴112安装到第二轴通孔152内时，可以减少喷臂100的晃动。同时，凸缘156和进水轴112配合可以避免杂物从第二连接轴15上端进入第二轴通孔152内卡滞滚珠330，有利于增加喷臂组件1000的可靠性。凸缘156与第二连接轴15可为一体成型结构或凸缘156可拆卸地安装在第二连接轴15的上端。
在某些实施方式中，喷臂12包括相对进水轴112对称设置的两个子臂114，第二连接轴15的上端面和子臂114的下表面间隔。第二连接轴15的上端面和子臂114的下表面间隔可以避免子臂114的下表面与第二连接轴15接触，喷臂100旋转时，子臂114的下表面不会与喷臂座200产生滑动摩擦，进一步减少了驱动喷臂100旋转的动力损失，提高了驱动喷臂100旋转的动力的利用率，使得水从喷臂100喷孔喷出后压力更大，利于增加喷臂组件1000的洗净效果。
具体地，在一个例子中，凸缘156的上表面和子臂114的下表面间隔。
在其他实施方式中，子臂114是数量可以不限于两个，而可以根据实际需要设置三个或三个以上的子臂114，在此不做具体限定。
在某些实施方式中，第二连接轴15的外侧面形成有螺纹158，安装部122的内侧面对应形成有螺纹。如此，第二连接轴15和安装部122之间通过螺纹配合固定连接。
当然，在其他实施方式中，第二连接轴15和安装部122还可以通过卡扣配合连接、过盈配合连接或其他连接方式固定连接。在此不做具体限定。
需要说明的是，在某些实施方式中，喷臂组件1000可以省略第二连接轴15，而第二滚珠槽154可以形成于安装部122的内侧面。同样地，可以使得喷臂100可以平稳地绕进水轴112的轴线X相对喷臂座200旋转。相应地，凸缘156可以位于安装部122的上端且部分地遮挡滚珠330。其中，凸缘156可以设计成可拆卸地安装在安装部122的上端，如此， 可以方便滚珠330从安装空间1222上方安装到安装部122的内侧面和进水轴112的外侧面之间。
进一步地，在图示的实施方式中，第一连接轴14位于进水轴112的外侧面和第二连接轴15的内侧面之间。如此，可以将带有滚珠330的第一连接轴14安装到进水轴112的外侧面和第二连接轴15的内侧面之间，有利于喷臂组件1000的装配。
在某些实施方式中，喷臂座200包括连接安装部122的进水部124，进水轴112和进水部124同轴设置，进水轴112开设有第一进水通孔1124，进水部124开设有第二进水通孔1242，第一进水通孔1124的孔径D1和第二进水通孔1242的孔径D2相等。
可以理解，进水部124和进水轴112可以呈圆管状，进水轴112和进水部124同轴设置可以使得第一进水通孔1124和第二进水通孔1242对准，如此，从第二进水通孔1242流出的水可以顺利进入第一进水通孔1124到达喷臂100内，保持喷臂组件1000内水路流通稳定通畅。
请结合图10，在某些实施方式中，喷臂座200包括连接安装部122和进水部124的台阶部126，进水轴112的底部与台阶部126间隔形成有0.4～2.2mm的间隙d。
如此，间隙d可以避免进水轴112的底部与喷臂座200接触，喷臂100旋转时，进水轴112底部不会与喷臂座200产生滑动摩擦，进一步减少了驱动喷臂100旋转的动力损失，提高了驱动喷臂100旋转的动力的利用率，使得水从喷臂100喷孔喷出后压力更大，利于增加喷臂组件1000的洗净效果。此外，间隙d较小可以减少水从间隙d流出，同时避免水中的杂质从间隙d进入进水轴112的安装部122之间影响滚珠330滚动。
在某些实施方式中，请结合图10，第二连接轴15和第一连接轴14设置在台阶部126的上方。
请结合图12，本申请实施方式的洗涤电器10000包括上述任一实施方式的喷臂组件1000。
进一步地，洗涤电器10000还包括腔体20，喷臂组件1000安装在腔体20，喷臂100位于腔体20内。
上述洗涤电器10000中，喷臂组件1000的喷臂100旋转时，滚珠330能够实现喷臂100和喷臂座200的滚动摩擦，使得喷臂100与喷臂座200间的摩擦力是滚动摩擦力，如此，减少了驱动喷臂100旋转的动力损失，提高了驱动喷臂100旋转的动力的利用率，使得水从喷臂100喷孔喷出后压力更大，利于增加喷臂组件1000和洗涤电器10000的洗净效果。其中，喷臂组件1000由于采用滚珠330进行装配，需要的安装空间1222较小，可以节省洗涤电器10000内部空间，增加腔体20内部10mm～40mm的装载量。腔体20用于放置需要清洗的物品，如餐具等。
在图示的实施例中，喷臂组件1000是洗涤电器10000的下喷臂组件1000，安装在腔体20的底部。在其他实施方式中，喷臂组件1000还可以作为其他位置的喷臂组件1000，例如上喷臂100、中喷臂100等，相应地，喷臂组件1000可以安装在腔体20的顶部、侧壁等，在此不做具体限定。
洗涤电器10000可以为洗碗机等使用喷臂100对物品进行清洗的洗涤电器。
