喷臂组件100C工作时，洗涤水从喷臂座10C的进水口102C依次进入喷臂座10C的水流通道101C、喷臂主体20C的第一内腔201C，然后分别从第二出水口210C和第三出水口220C流出喷臂主体20C，并分两路进入第一喷臂副体30C的第二内腔301C和第二喷臂副体40C的第三内腔401C内，最终从第一喷臂副体30C上的多个第一喷射孔302C和第二喷臂副体 40C上的多个第二喷射孔402C喷出，在喷出的洗涤水的反向作用力下，第一喷臂副体30C和第二喷臂副体40C分别绕其对应位置上的转轴的中心轴线转动，与此同时，在齿轮组件50C的传动作用下，喷臂主体20C绕喷臂座10C的中心轴线转动，使得从第一喷射孔302C和第二喷射孔402C喷出的洗涤水的洗涤区域叠加大致形成正方形。
由此，根据本发明实施例的用于洗碗机的喷臂组件100C，通过设置齿轮组件50C，可以实现第一喷臂副体30C和第二喷臂副体40C的自转和公转，喷臂组件100C的两个喷臂副体上的喷射孔的洗涤区域的叠加可以形成正方形、无死角的洗涤区域，该喷臂组件100C的结构简单，各部件连接可靠，装拆方便，可以实现正方形的洗涤区域，洗涤效果好，洗涤效率高，用户体验好。
在本发明的一些具体实施方式中，水流通道101C沿喷臂座10C的轴向方向延伸，第一出水口103C设在喷臂座10C的另一端的侧壁上。参照图2和图4，喷臂座10C的第一端(如图4所示的上端)的外侧壁设有与水流通道101C导通的第一出水口103C，第一出水口103C沿喷臂座10C的侧壁的周向延伸，喷臂主体20C与喷臂座10C的第一端相连且喷臂座10C的第一出水口103C与喷臂主体20C的第一内腔201C导通。由此，通过将第一出水口103C设在喷臂座10C的侧壁，可以保证单位时间内、较大的进水通量，从而为洗碗机提供足量的洗涤水，大大地提高了洗涤效率。
其中，喷臂组件100C还包括第一滑动环61C，喷臂座10C上设有第一滑动配合槽104C，第一滑动环61C可转动地套设在第一滑动配合槽104C上，喷臂主体20C上设有第一通孔202C，第一通孔202C的外周沿向下延伸并与第一滑动环61C相连。
具体地，如图2所示，喷臂座10C的第一端(如图2所示的上端)的外侧壁设有与水流通道101C不导通的第一滑动配合槽104C，第一滑动配合槽104C形成沿喷臂座10C的周向延伸的环形，并且第一滑动配合槽104C位于第一出水口103C的下方，第一滑动环61C套设在喷臂座10C的上端且第一滑动环61C的内圈与喷臂座10C上的第一滑动配合槽104C配合，喷臂主体20C的下表面设有与第一内腔201C导通的第一通孔202C，喷臂座10C的上端通过第一通孔202C、伸入喷臂座10C的第一内腔201C内且与喷臂主体20C的上表面卡接相连，而喷臂主体20C的邻近第一通孔202C的外周沿向外弯折以与第一滑动环61C配合。
由此，通过在第一出水口103C的下方设置第一滑动配合槽104C和与其配合的第一滑动环61C，可以实现喷臂主体20C与第一滑动环61C的固定连接，并可以实现喷臂座10C与喷臂主体20C之间的可枢转连接，保证喷臂主体20C可以绕喷臂座10C的中心轴线转动，实现第一喷臂副体30C和第二喷臂副体40C的公转，从而实现喷臂组件100C的正方形、无死角的洗涤区域。
喷臂组件100C还包括第二滑动环62C和第三滑动环63C，喷臂主体20C上设有与第二 出水口210C连通的第一定位轴211C，第一定位轴211C上设有第二滑动配合槽212C，第二滑动环62C可转动地套设在第二滑动配合槽212C上，第一喷臂副体转轴33C的一端设有第二通孔303C，第二通孔303C的外周沿向下延伸并与第二滑动环62C相连，齿轮组件50C与第二滑动环62C相连。进一步地，喷臂主体20C上设有与第三出水口220C连通的第二定位轴221C，第二定位轴221C上设有第三滑动配合槽222C，第三滑动环63C可转动地套设在第三滑动配合槽222C上，第二喷臂副体转轴42C的一端设有第三通孔403C，第三通孔403C的外周沿向下延伸并与第三滑动环63C相连，齿轮组件50C与第三滑动环63C相连。
也就是说，该用于洗碗机的喷臂组件100C主要由喷臂座10C、喷臂主体20C、第一喷臂副体30C、第二喷臂副体40C、齿轮组件50C、第一滑动环61C、第二滑动环62C和第三滑动环63C组成。其中，喷臂座10C的上端的侧壁设有沿其周向延伸的第一滑动配合槽104C，喷臂主体20C的两端的上表面分别设有沿喷臂座10C的轴向延伸的第一定位轴211C和第二定位轴221C，第一定位轴211C的侧壁设有沿其周向延伸的第二滑动配合槽212C，第二定位轴221C的侧壁设有沿其周向延伸的第三滑动配合槽222C，第一滑动环61C套设在喷臂座10C上且第一滑动环61C的内圈与喷臂座10C的第一滑动配合槽104C可枢转地配合，第二滑动环62C套设在喷臂主体20C的第一定位轴211C上且第二滑动环62C的内圈与第一定位轴211C上的第二滑动配合槽212C可枢转地配合，第三滑动环63C套设在喷臂主体20C的第二定位轴221C上且第三滑动环63C的内圈与第二定位轴221C上的第三滑动配合槽222C可枢转地配合。
其中，第一喷臂副体转轴33C的一端设有与第二内腔301C导通的第二通孔303C，第二喷臂副体转轴42C的一端设有与第三内腔401C导通的第三通孔403C，喷臂主体20C上的第一定位轴211C通过第二通孔303C、伸入第一喷臂副体转轴33C的第二通孔303C内，第一定位轴211C上的第二滑动环62C的外圈与第一喷臂副体转轴33C固定相连，以使第一喷臂副体30C以及第二滑动环62C可以绕第一定位轴211C的中心轴线转动，喷臂主体20C上的第二定位轴221C通过第三通孔403C、伸入第二喷臂副体转轴42C的第三通孔403C内，第二定位轴221C上的第三滑动环63C的外圈与第二喷臂副体转轴42C固定相连，以使第二喷臂副体40C以及第三滑动环63C可以绕第二定位轴221C的中心轴线转动。
具体地，喷臂主体20C的邻近第一通孔202C的外周沿向下延伸且弯折以与第一滑动环61C卡接相连，第一喷臂副体30C的邻近第二通孔303C的外周沿向下延伸且弯折以与第二滑动环62C卡接相连，第二喷臂副体40C的邻近第三通孔403C的外周沿向下延伸且弯折以与第三滑动环63C卡接相连。齿轮组件50C分别与第一滑动环61C、第二滑动环62C和第三滑动环63C相连，当喷臂组件100C工作时，第一喷臂副体30C和第二喷臂副体40C在喷出的洗涤水的反向驱动下、开始转动，然后通过齿轮组件50C的传动，可以实现驱动喷臂主体 20C绕喷臂座10C的中心轴线转动的目的。
由此，通过在喷臂主体20C上的第一定位轴211C和第二定位轴221C上设置与第二滑动环62C和第三滑动环63C配合的第二滑动配合槽212C和第三滑动配合槽222C，可以实现第一喷臂副体30C与第一定位轴211C、第二喷臂副体40C与第二定位轴221C的可枢转连接，保证第一喷臂副体30C和第二喷臂副体40C可绕其对应的旋转中心轴线转动，实现第一喷臂副体30C和第二喷臂副体40C的自转，从而实现喷臂组件100C的正方形、无死角的洗涤区域。
如图2和图9所示，在本发明的一些具体实施方式中，齿轮组件50C包括中心齿轮51C、第一齿轮组52C和第二齿轮组53C。具体而言，中心齿轮51C设有定位槽511C，喷臂座10C的另一端设有配合部11C，配合部11C与第一滑动环61C相连，配合部11C穿过第一通孔202C伸入定位槽511C内与中心齿轮51C相连，第一齿轮组52C与中心齿轮51C啮合且与第二滑动环62C相连以由第二滑动环62C驱动，第二齿轮组53C与中心齿轮51C啮合且与第三滑动环63C相连以由第三滑动环63C驱动。
换言之，喷臂组件100C的齿轮组件50C主要由中心齿轮51C、第一齿轮组52C和第二齿轮组53C组成，其中，喷臂座10C的第一端(如图2所示的上端)伸出喷臂主体20C的上表面，中心齿轮51C套设在喷臂座10C的上端且与喷臂座10C的上端卡接相连，具体地，中心齿轮51C的中部设有定位槽511C，喷臂座10C的第一端设有配合部11C，喷臂座10C的配合部11C的至少一部分伸出喷臂主体20C的上表面且与中心齿轮51C的定位槽511C卡接相连，喷臂座10C的第一滑动配合槽104C与位于喷臂主体20C下方的第一滑动环61C可枢转地相连。例如，中心齿轮51C安装在喷臂座10C的顶部，两者可以通过花键配合部11C实现固定连接。
第一齿轮组52C设在第一喷臂副体30C的下方且与第一喷臂副体30C上的第二滑动环62C固定相连，第一喷臂副体30C绕喷臂主体20C的第一定位轴211C的中心轴线转动时，可以带动第一齿轮组52C转动，第二齿轮组53C设在第二喷臂副体40C的下方且与第二喷臂副体40C上的第三滑动环63C固定相连，第二喷臂副体40C绕喷臂主体20C上的第二定位轴221C的中心轴线转动时，可以带动第二齿轮组53C转动，二者同时与中心齿轮51C啮合传动，再加上中心齿轮51C相对于水平面固定设置，使得第一齿轮组52C和第二齿轮组53C分别沿中心齿轮51C的周向转动，从而实现喷臂主体20C绕喷臂座10C的中心轴线转动。
可选地，根据本发明的一个实施例，第一齿轮组52C的齿轮个数为偶数，第二齿轮组53C的齿轮个数为偶数。由此，通过调节第一齿轮组52C以及第二齿轮组53C的齿轮个数、齿轮齿数，可以调节第一喷臂副体30C和第二喷臂副体40C的自转的转速和转动方向，从而实现预定的洗涤效率。
具体地，根据本发明的一个实施例，第一齿轮组52C包括位于喷臂主体20C外侧的第一行星齿轮521C，第一行星齿轮521C与第二滑动环62C相连且由第二滑动环62C驱动，第一行星齿轮521C与中心齿轮51C传动；第二齿轮组53C包括位于喷臂主体20C外侧的第二行星齿轮531C，第二行星齿轮531C与第三滑动环63C相连且由第三滑动环63C驱动，第二行星齿轮531C与中心齿轮51C传动。
例如，第一齿轮组52C由双数级齿轮构成，如二级和四级，其中，最靠外的行星齿轮为第一行星齿轮521C，第一行星齿轮521C通过第二滑动环62C与第一喷臂副体30C连接为一体。第二齿轮组53C由双数级齿轮构成，如二级和四级，其中，最靠外的为第二行星齿轮531C，第二行星齿轮531C通过第三滑动环63C与第二喷臂副体40C连接为一体。除了第一行星齿轮521C和第二行星齿轮531C之外，其他行星齿轮均为传动齿轮。喷臂主体20C作为第一行星齿轮521C和第二行星齿轮531C的行星架，随着第一行星齿轮521C和第二行星齿轮531C的自转，喷臂主体20C连同两个行星齿轮绕着喷臂座10C中心轴进行公转。
参照图2，第一行星齿轮521C套设在第二滑动环62C的外侧且与第二滑动环62C卡接相连，而第一喷臂副体30C与第二滑动环62C的外圈卡接相连以带动第二滑动环62C一起转动，第二滑动环62C套设在喷臂主体20C的第一定位轴211C上且可与第一行星齿轮521C、第一喷臂副体30C一起绕第一定位轴211C的中心轴线转动；第二行星齿轮531C套设在第三滑动环63C的外侧且与第三滑动环63C卡接相连，而第二喷臂副体40C与第三滑动环63C的外圈卡接相连以带动第三滑动环63C一起转动，第三滑动环63C套设在喷臂主体20C上的第二定位轴221C上且可与第二行星齿轮531C、第二喷臂副体40C一起绕第二定位轴221C的中心轴线转动，中心齿轮51C设在第一行星齿轮521C与第二行星齿轮531C之间且与喷臂座10C的第一端固定连接。
当喷臂组件100C工作时，第一喷臂副体30C和第二喷臂副体40C在喷出的洗涤水的反向驱动下开始自转，即第一喷臂副体30C绕第一定位轴211C的中心轴线转动，第二喷臂副体40C绕第二定位轴221C的中心轴线转动，与此同时，第一喷臂副体30C和第二喷臂副体40C分别带动第一行星齿轮521C和第二行星齿轮531C开始自转，由于第一行星齿轮521C和第二行星齿轮531C分别与中心齿轮51C啮合传动，而中心齿轮51C固设在喷臂座10C的上端，因此，第一行星齿轮521C和第二行星齿轮531C分别沿中心齿轮51C的周向转动，从而实现喷臂主体20C的自转，即实现第一喷臂副体30C和第二喷臂副体40C的公转的目的。
可选地，根据本发明的一个实施例，齿轮组件50C还包括第一传动齿轮522C和第二传动齿轮532C，第一传动齿轮522C与第一行星齿轮521C和中心齿轮51C啮合，第二传动齿轮532C与第二行星齿轮531C和中心齿轮51C啮合。具体地，第一传动齿轮522C通过传动齿轮滑动环64C与喷臂主体20C的主翼21C实现可枢转地连接，第一传动齿轮522C设在中 心齿轮51C与第一行星齿轮521C之间且分别与中心齿轮51C和第一行星齿轮521C外啮合传动；第二传动齿轮532C通过传动齿轮滑动环64C与喷臂主体20C的副翼22C实现可枢转地连接，第二传动齿轮532C设在中心齿轮51C与第二行星齿轮531C之间且分别与中心齿轮51C和第二行星齿轮531C外啮合传动。由此，可以保证喷臂组件100C在一定宽度尺寸范围内、改变齿轮组件50C的第一齿轮组52C和第二齿轮组53C的传动比，并且可以起到传递运动和动力的作用，实现第二行星齿轮531C与中心齿轮51C的传动，保证该喷臂组件100C的洗涤效果。
优选地，根据本发明的一个实施例，中心齿轮51C、第一行星齿轮521C、第二行星齿轮531C、第一传动齿轮522C和第二传动齿轮532C的中心位于同一直线上。即两组行星齿轮分设中心齿轮51C的两侧，都是外啮合关系，由于中心齿轮51C是固定的，从而可知第一行星齿轮521C的自转方向和公转方向相反，第二行星齿轮531C的自转方向和公转方向相反。
具体地，如图9所示，第一行星齿轮521C、第一传动齿轮522C、中心齿轮51C、第二传动齿轮532C和第二行星齿轮531C沿直线方向依次布置，并且相邻两个齿轮之间为外啮合传动。若第一行星齿轮521C在其上的多个第一喷射孔302C喷出的洗涤水的反向作用力、绕第一定位轴211C的中心轴线顺时针旋转，由于第一行星齿轮521C与第一传动齿轮522C为外啮合传动，因此，第一传动齿轮522C绕其自身的旋转轴线逆时针旋转，由于中心齿轮51C固定不动，而第一传动齿轮522C与中心齿轮51C为外啮合关系，因此，喷臂主体20C开始绕喷臂座10C的中心轴线逆时针转动，即第一行星齿轮521C的自转和公转的方向相反，与此同时，中心齿轮51C与第二行星齿轮531C之间的第二传动齿轮532C同样绕自身中心轴线顺时针转动，由于第二行星齿轮531C与第二传动齿轮532C为外啮合关系，因此第二行星齿轮531C与第二传动齿轮532C的转动方向相反，即第二行星齿轮531C绕第二定位轴221C的中心轴线顺时针转动，即第二行星齿轮531C的自转和公转的方向相反，第一行星齿轮521C与第二行星齿轮531C的自转方向相同。
再者，将中心齿轮51C、第一行星齿轮521C、第二行星齿轮531C和传动齿轮的中心设置在同一直线上，有利于减小喷臂组件100C的宽度尺寸，增加喷臂组件100C的洗涤区域的长度范围，从而实现正方形、无死角的洗涤区域。
这里需要说明的是，第一行星齿轮521C上的第一喷射孔302C的设置方向、第二行星齿轮531C上的第二喷射孔402C的设置方向与传动齿轮的个数和设置位置相关，若第一行星齿轮521C与中心齿轮51C之间设置的传动齿轮的个数为偶数，而第二行星齿轮531C与中心齿轮51C之间设置的传动齿轮的个数为奇数，则第一喷射孔302C和第二喷射孔402C的设置方向相反，即第一喷臂副体30C和第二喷臂副体40C的自转方向相反，具体可以根据设计需求改变传动齿轮的个数和设置位置。
在本发明的一些具体示例中，中心齿轮51C与第一传动齿轮522C的齿数比为2:1，多个第一传动齿轮522C等速传动。可选地，第一行星齿轮521C与第一传动齿轮522C可以为相同的齿轮，即第一行星齿轮521C与第一传动齿轮522C的齿数和模数相等，由于第一行星齿轮521C与第一传动齿轮522C的齿数比为1：1，中心齿轮51C的齿数与第一传动齿轮522C的齿数比为2：1，中心齿轮51C的分度圆半径R1与第一传动齿轮522C的分度圆半径R21的比为2:1，第一传动齿轮522C分别与第一行星齿轮521C和中心齿轮51C直接外啮合传动，第一传动齿轮522C为等速传动。
例如，中心齿轮51C具有80个齿，第一传动齿轮522C就是40个齿。同时，其他各级齿轮传动为等速传动。中心齿轮51C的分度圆半径R1和第一传动齿轮522C的分度圆半径R21为2:1。因此，第一行星齿轮521C的公转轨迹半径R31等于第一传动齿轮522C的分度圆半径R21的(2N+1)倍，其中，N为第一齿轮组52C传动级数，如二级和四级。
而中心齿轮51C与第二传动齿轮532C的齿数比为2:1，多个第二传动齿轮532C等速传动。可选地，第二行星齿轮531C与第二传动齿轮532C可以为相同的齿轮，即第二行星齿轮531C与第二传动齿轮532C的齿数和模数相等，由于第二行星齿轮531C与第二传动齿轮532C的齿数比为1：1，中心齿轮51C的齿数与第二传动齿轮532C的齿数比为2：1，中心齿轮51C的分度圆半径R1与第二传动齿轮532C的分度圆半径R22为2:1。第二传动齿轮532C分别与第二行星齿轮531C和中心齿轮51C直接外啮合传动，第二传动齿轮532C为等速传动。
例如，中心齿轮51C具有80个齿，第二传动齿轮532C就是40个齿。同时，其他各级齿轮传动为等速传动。中心齿轮51C的分度圆半径R1和第二传动齿轮532C的分度圆半径R22为2:1。因此，第二行星齿轮531C的公转轨迹半径R32等于第二传动齿轮532C的分度圆半径R22的(2N+1)倍，其中，N为第一齿轮组52C传动级数，如二级和四级。
在本发明的一些具体事例中，第一喷臂副体30C的自转与公转方向相反，且自转与公转的转速比为1:1，第二喷臂副体40C的自转与公转方向相反，且自转与公转的转速比为1:1。
具体地，第一行星齿轮521C、第一传动齿轮522C、中心齿轮51C、第二传动齿轮532C和第二行星齿轮531C沿直线方向依次布置，并且相邻两个齿轮之间为外啮合传动。若第一行星齿轮521C在其上的多个第一喷射孔302C喷出的洗涤水的反向作用力、绕第一定位轴211C的中心轴线顺时针旋转，由于第一行星齿轮521C与第一传动齿轮522C为外啮合传动，因此，第一传动齿轮522C绕其自身的旋转轴线逆时针旋转，由于中心齿轮51C固定不动，而第一传动齿轮522C与中心齿轮51C为外啮合关系，因此，喷臂主体20C开始绕喷臂座10C的中心轴线逆时针转动，即第一行星齿轮521C的自转和公转的方向相反，与此同时，中心齿轮51C与第二行星齿轮531C之间的第二传动齿轮532C同样绕自身中心轴线顺时针转动，由于第二行星齿轮531C与第二传动齿轮532C为外啮合关系，因此第二行星齿轮531C与第 二传动齿轮532C的转动方向相反，即第二行星齿轮531C绕第二定位轴221C的中心轴线顺时针转动，即第二行星齿轮531C的自转和公转的方向相反，第一行星齿轮521C与第二行星齿轮531C的自转方向相同。并且，根据齿轮传动比和啮合关系，可知第一喷臂副体30C的自转和公转的转速比为1：1.第二喷臂副体40C的自转和公转的转速比为1：1。
其中，如图7和图12所示，根据本发明的一个实施例，第二喷臂副体40C包括多个相对于第二喷臂副体转轴42C的中心轴线中心对称的第二喷臂41C，每个第二喷臂41C上分别设有第二喷射孔402C，相邻两个第二喷臂41C上的第二喷射孔402C的运动轨迹线的相位差为相应两个第二喷臂41C间相位差的1/2。
具体地，第二喷臂副体40C可转动地设在喷臂主体20C的副翼22C上，第二喷臂副体40C内限定有与第三出水口220C连通的第三内腔401C，第二喷臂副体40C包括多个第二喷臂41C，多个第二喷臂41C呈发散状布置在水平面上，其中，多个第二喷臂41C的一端相互连通，多个第二喷臂41C的另一端远离第二喷臂副体转轴42C的中心轴线，每个第二喷臂41C可以形成布置在水平面上的长条状且每个第二喷臂41C的上表面设有多个间隔开布置的第二喷射孔402C，第二喷臂副体40C的下表面设有与副翼22C相连的第二喷臂副体转轴42C，第二喷臂副体40C可以绕第二喷臂副体转轴42C的中心轴线转动。优选地，第二喷臂副体40C的多个第二喷臂41C呈中心对称布置，若第二喷臂副体40C的相邻两个第二喷臂41C之间的相位差为α，则这两个第二喷臂41C上的第二喷射孔402C的运动轨迹的相位差为0.5α。第二喷臂副体40C上的多个第二喷射孔402C可以喷射到正方形洗涤区域的四个死角位置以及正方形中部区域，从而有利于实现喷臂组件100C的正方形洗涤区域，提高洗涤效果。
可选地，第一喷臂31C和第二喷臂41C分别为4个。参照图6，第一喷臂副体30C包括四个呈中心对称布置的第一喷臂31C，每个第一喷臂31C的长度相等，并且每个第一喷臂31C上的第一喷射孔302C的数量相等、位置一一对应，参照图7，第二喷臂副体40C包括四个呈中心对称布置的第二喷臂41C，四个第二喷臂41C中相对设置的两个为长臂，四个第二喷臂41C中相对设置的另两个为短臂，每个长臂上的第二喷射孔402C的数量相等、位置一一对应，每个短臂上的第二喷射孔402C的数量相等、位置一一对应。
其中，如图11和图12所示，根据本发明的一个实施例，第一喷射孔302C和第二喷射孔402C的喷射轨迹线满足参数方程：x＝A*cos(ang)+B*cos(ang)，y＝A*sin(ang)-B*sin(ang)，其中ang为喷臂主体20C转过的角度，0°＜ang＜360°，A为第一喷臂副体转轴33C或第二喷臂副体转轴42C到喷臂座10C的中心轴线的距离，B为第一喷射孔302C到第一喷臂副体转轴33C的距离或第二喷射孔402C到第二喷臂副体转轴42C的距离。
由此，第一喷射孔302C和第二喷射孔402C的运动轨迹均为椭圆线，并且同一个第一喷 臂31C或者第二喷臂41C上的喷射孔形成的运动轨迹的相位差为0度，相邻两个第一喷臂31C上的第一喷射孔302形成的运动轨迹之间的相位差是该两个第一喷臂31C之间的相位差的一半，相邻两个第二喷臂41C上的第二喷射孔402形成的运动轨迹之间的相位差是该两个第二喷臂41C之间的相位差的一半，最终使得喷臂组件100C的两个喷臂副体上的多个喷射孔的洗涤区域的叠加可以形成正方形、无死角的洗涤区域，洗涤效果好，洗涤效率高，用户体验好。
第一喷臂副体30C和第二喷臂副体40C的动轨迹线的相位差角度，等于第一喷射孔302C和第二喷射孔402C与所在第一喷臂副体转轴33C和第二喷臂副体转轴42C的连线之间相位差角度的1/2。

下面结合具体实施例对本发明实施例的用于洗碗机的喷臂组件100C进行描述。
如图1至图9所示，用于洗碗机的喷臂组件100C主要由喷臂座10C、喷臂主体20C、第一喷臂副体30C、第二喷臂副体40C、第一行星齿轮521C、第二行星齿轮531C、中心齿轮51C、第一传动齿轮522C、第二传动齿轮532C、第一滑动环61C、第二滑动环62C、第三滑动环63C组成。
其中如图2和图4所示，喷臂座10C形成沿竖直方向(如图4所示的上下方向)延伸的柱状，喷臂座10C内限定有两端导通且沿其轴向延伸水流通道101C，喷臂座10C的下端设有与水流通道101C导通的进水口102C，喷臂座10C的上端的侧壁设有沿其周向延伸的第一出水口103C，而喷臂座10C的侧壁还设有第一滑动配合槽104C，该第一滑动配合槽104C形成沿喷臂座10C的周向延伸的环形且位于第一出水口103C的下方，喷臂座10C的上端具有位于第一出水口103C上方的花键配合部11C。
如图2和图5所示，喷臂主体20C可转动地设在喷臂座10C上且可以绕喷臂座10C的中心轴线转动，喷臂主体20C形成布置在水平面内的长条板件，喷臂主体20C内限定有与水流通道101C导通的第一内腔201C，喷臂主体20C主要由位于喷臂主体20C的中心轴线两侧的主翼21C和副翼22C组成，其中，主翼21C的上表面设有第一定位轴211C，第一定位轴211C的中部设有与第一内腔201C导通的第二出水口210C，第一定位轴211C的侧壁设有第二滑动配合槽212C，第二滑动配合槽212C形成沿第一定位轴211C的周向延伸的环形，副翼22C的上表面设有第二定位轴221C，第二定位轴221C的中部设有与第一内腔201C导通的第三 出水口220C，第二定位轴221C的侧壁设有第三滑动配合槽222C，第三滑动配合槽222C形成沿第二定位轴221C的周向延伸的环形，喷臂主体20C的下表面设有第一通孔202C，喷臂座10C的上端通过第一通孔202C、伸入第一内腔201C内，且穿过主翼21C与副翼22C的连接位置处的上表面。
第一滑动环61C套设在喷臂座10C上且与喷臂座10C上的第一滑动配合槽104C可枢转地相连，第一滑动环61C与喷臂主体20C卡接相连，以随喷臂主体20C一起绕喷臂座10C的中心轴线转动，第二滑动环62C套设在第一定位轴211C上且与第二滑动配合槽212C可枢转地配合，第三滑动环63C套设在第二定位轴221C上且与第三滑动配合槽222C可枢转地配合。
如图2和图9所示，中心齿轮51C设在喷臂主体20C的上方且伸出喷臂主体20C的上表面的喷臂座10C固定相连，具体地，中心齿轮51C的中部设有定位槽511C，喷臂座10C的上端的花键配合部11C与定位槽511C卡接相连，以使中心齿轮51C与喷臂座10C固定相连，保证中心齿轮51C在喷臂组件100C工作时不发生转动。第一行星齿轮521C套设在第二滑动环62C的外侧且与第二滑动环62C卡接相连以保证第一行星齿轮521C与第二滑动环62C一起绕第一定位轴211C的中心轴线转动。第二行星齿轮531C套设在第三滑动环63C的外侧且与第三滑动环63C卡接相连以保证第二行星齿轮531C与第三滑动环63C一起绕第二定位轴221C的中心轴线转动。第一传动齿轮522C可转动地设在喷臂主体20C上且位于中心齿轮51C与第一行星齿轮521C之间，第一传动齿轮522C分别与中心齿轮51C和第一行星齿轮521C外啮合传动，第二传动齿轮532C可转动地设在喷臂主体20C上且位于中心齿轮51C与第二行星齿轮531C之间，第二传动齿轮532C分别与中心齿轮51C和第二行星齿轮531C外啮合传动。
如图2和图6所示，第一喷臂副体30C布置在水平面内，第一喷臂副体30C内限定有第二内腔301C，第一喷臂副体30C的下表面设有第一喷臂副体转轴33C，第一喷臂副体转轴33C的中部具有与第二内腔301C导通的第二通孔303C，喷臂主体20C的第一定位轴211C伸入第二通孔303C内且与第一喷臂副体30C可枢转地相连，第一喷臂副体转轴33C与第二滑动环62C卡接相连，以带动第二滑动环62C一起转动，具体地，第一喷臂副体30C包括四个相对于第一喷臂副体转轴33C的中心轴线呈中心对称布置的第一喷臂31C，四个第一喷臂31C的一端相互连通，四个第一喷臂31C的另一端向远离第一喷臂副体转轴33C的中心轴线的方向延伸，每个第一喷臂31C上设有多个间隔开布置的第一喷射孔302C。
如图2和图7所示，第二喷臂副体40C布置在水平面内，第二喷部副体内限定有第三内腔401C，第二喷臂副体40C的下表面设有第二喷臂副体转轴42C，第二喷臂副体转轴42C的中部具有与第三内腔401C导通的第三通孔403C，喷臂主体20C的第二定位轴221C伸入第三通孔403C内且与第二喷臂副体40C可枢转地相连，第二喷臂副体转轴42C与第三滑动环 63C卡接相连，以带动第三滑动环63C一起转动，具体地，第二喷臂副体40C包括四个相对于第二喷臂副体转轴42C的中心轴线呈中心对称布置的第二喷臂41C，四个第二喷臂41C的一端相互连通，四个第二喷臂41C的另一端向远离第二喷臂副体转轴42C的中心轴线的方向延伸，每个第二喷臂41C上设有多个间隔开布置的第二喷射孔402C，其中，四个第二喷臂41C中相对设置的两个为长臂，四个第二喷臂41C中相对设置的另两个为短臂。
本实施例中，第一行星齿轮521C、第一传动齿轮522C、中心齿轮51C、第二传动齿轮532C、第二行星齿轮531C的中心共线排列，第一行星齿轮521C和第二行星齿轮531C分设中心齿轮51C的两侧。由于中心齿轮51C是固定的，从而可知第一行星齿轮521C的自转方向和公转方向相反，第二行星齿轮531C的自转方向和公转方向相反。
喷臂组件100C工作时，洗涤水从喷臂座10C的进水口102C依次进入喷臂座10C的水流通道101C、喷臂主体20C的第一内腔201C，然后分别从第二出水口210C和第三出水口220C流出喷臂主体20C，并分两路进入第一喷臂副体30C的第二内腔301C和第二喷臂副体40C的第三内腔401C内，最终从第一喷臂副体30C上的多个第一喷射孔302C和第二喷臂副体40C上的多个第二喷射孔402C喷出，在喷出的洗涤水的反向作用力下，第一喷臂副体30C和第二喷臂副体40C分别绕其对应位置上的转轴的中心轴线转动，与此同时，第一喷臂副体30C和第二喷臂副体40C分别带动第一行星齿轮521C和第二行星齿轮532C自转，由于中心齿轮51C固定在喷臂主体20C上，而第一行星齿轮521C通过第一传动齿轮522C与中心齿轮51C啮合传动，第二行星齿轮531C通过第二传动齿轮532C与中心齿轮51C啮合传动，使得喷臂主体20C绕中心齿轮51C的中心线转动，最终洗涤水从第一喷射孔302C和第二喷射孔402C喷出，形成的洗涤区域叠加大致形成正方形。
其中，中心齿轮51C和第一传动齿轮522C的齿数比为2:1，具体为中心齿轮51C具有60个齿，第一传动齿轮522C具有30个齿。同时，其他各级齿轮传动为等速传动。进一步地，中心齿轮51C的分度圆半径R1和第一传动齿轮522C的分度圆半径R21为2:1，具体为R1等于72mm，R21等于36mm。因此，二级传动的情况下，第一行星齿轮521C的公转轨迹半径R31等于第一传动齿轮522C的分度圆半径R21的5倍，即180mm。中心齿轮51C和第二传动齿轮532C的齿数比为2:1，具体为中心齿轮51C具有60个齿，第二传动齿轮532C具有30个齿。同时，其他各级齿轮传动为等速传动。进一步地，中心齿轮51C的分度圆半径R1和第二传动齿轮532C的分度圆半径R22为2:1，具体为R1等于72mm，R22等于36mm。因此，二级传动的情况下，第二行星齿轮531C的公转轨迹半径R32等于第二传动齿轮532C的分度圆半径R22的5倍，即180mm。
喷臂主体20C作为第一行星齿轮521C、第二行星齿轮531C的行星架，随着第一行星齿轮521C、第二行星齿轮531C的自转，喷臂主体20C连同第一行星齿轮521C、第二行星齿轮 531C绕着喷臂座10C的中心轴线进行公转。根据齿轮传动比和啮合关系，可知第一喷臂副体30C的自转与公转方向相反，转速比为1:1。同样地，第二喷臂副体40C的自转与公转方向相反，转速比为1:1。第一喷射孔302C和第二喷射孔402C的运动形成的轨迹线都是椭圆线，两个运动轨迹线的相位差角度，等于两个喷射孔与所在喷臂副体转轴的连线之间相位差角度的1/2。
其中，如图6和图11所示，第一喷臂副体30C具有四个呈中心对称布置的第一喷臂31C，相邻两个第一喷臂31C之间的相位角为60°和120°。每个第一喷臂31C分别设有第一喷射孔302C，四个第一喷臂31C上的第一喷射孔302C的运动轨迹线的相位差为对应第一喷臂31C间相位差的1/2，即30°和60°
如图7和图12所示，第二喷臂副体40C具有四个呈中心对称布置的第二喷臂41C，四个第二喷臂41C中相对设置的两个为长臂，四个第二喷臂41C中相对设置的两个为短臂，相邻两个第二喷臂41C的相位角为90°。每个第二喷臂41C分别设有第二喷射孔402C，四个第二喷臂41C上的第二喷射孔402C的运动轨迹的相位差为对应第二喷臂41C间相位差的1/2，即45°。
本实施例的用于洗碗机的喷臂组件100C具有两个喷臂副体，其中，第一喷臂副体30C上的多个第一喷射孔302C和第二喷臂副体40C上的多个第二喷射孔402C形成不同角度的椭圆轨迹线，如图13所示，两个喷臂副体配合，不同组的第一喷射孔302C和第二喷射孔402C的轨迹线相互交织，实现了对正方形洗涤区域的覆盖，从而解决了相关技术中的洗碗机的由于碗篮区域的四个角位置洗涤不良而造成整体洗净不佳的问题。
