具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的喷臂组件的进水结构1。
如图1-图15所示，根据本申请实施例的喷臂组件的进水结构1可以包括配水件100、过水管220、外壳400、卡接件500和支撑件600。
举例而言，在一些实施例中，本申请中的喷臂组件可以包括喷管2和进水结构1，喷管2和进水结构1可以应用于洗碗机中。进一步地，喷管2和进水结构1可以安装在洗碗机的洗涤腔内，进水结构1向喷管2供水，以利用喷管2喷淋出的洗涤水对洗涤腔内放置的待洗涤餐具进行喷淋洗涤。
当然，在另一些实施例中，喷臂组件的进水结构1也可以应用于蒸汽消毒柜、衣物处理装置等电器设备，进水结构1可以向喷管2供水或供气，以利用喷管2进行喷淋消毒或喷淋洗涤。
在本申请以下的实施方式中，以进水结构1应用于洗碗机为例进行说明。
例如，在一些示例中，喷臂组件可以包括配水件100、过水管220和喷管2，配水件100固定设置在洗碗机内，配水件100可以通过过水管220与喷管2连通，以用于向喷管2供水。配水件100的一端与外部水源相连且另一端具有配水接头，配水接头适于与过水管220连通，以通过配水件100向过水管220供水。过水管220相对配水 件100可转动，即过水管220可转动地设置在洗碗机内，这样过水管220与喷管2相连，过水管220可以驱动喷管2进行转动，喷管2的转动轴线沿其长度方向延伸，即喷管2的转动轴线沿其轴向延伸。由此，喷管2既与过水管220一起转动，喷管2又与过水管220流体连通。喷管2的管壁开设有多个喷孔，喷孔用于喷射出水流，这样进水水流在经配水件100、过水管220后可以流入喷管2中，以对洗涤腔内的待洗餐具进行冲洗。同时，过水管220可以带动喷管2进行转动，以便于增大喷管2的喷淋范围，提高喷管2的转动稳定性和可靠性，保证喷管2可以具有合适的喷射角度，提高喷臂组件的喷淋洗涤效果。
当然，在另一些示例中，过水管220可以与喷管2一体成型，即过水管220可以形成为喷管2的一部分，这样喷管2可以与配水件100直接连通。本申请中，进水结构1的配水件100固定设置在洗碗机内，配水件100具有进水通道101和与进水通道101相连的进水口、出水口102，进水口适于与外部水源处的自来水龙头相连。过水管220具有过水通道201，过水通道201与出水口102连通，过水管220相对配水件100可转动。过水通道201的一端与出水口102连通且另一端与喷管2相连。外壳400具有安装过口401和配合槽402，过水管220能够穿过安装过口401以与配水件100相配合。支撑件600适于配合在配合槽402内，过水管220可转动地穿设在支撑件600内，换言之，支撑件600可以套设在过水管220的外周壁，使过水管220相对支撑件600进行转动。卡接件500可以与过水管220进行卡接配合，卡接件500能够用于对过水管220和支撑件600进行限位。
根据本申请实施例的喷臂组件的进水结构1，通过在配水件100、过水管220和喷管2之间形成水流通道。这样可增加过水管220的功能性，不仅可以利用过水管220带动喷管2进行转动，保证喷管2可以稳定可靠地进行转动，便于准确控制喷管2的喷淋角度，使喷管2可以具有合适的喷射角度，便于提高喷臂组件的喷淋洗涤效果，便于增大喷管2的喷淋范围，提高洗碗机的洗涤效果。而且，通过在配水件100、过水管220和喷管2之间形成流体连通的通道，在需要向喷管2供水时，可以通过配水件100和过水管220将进水引入喷管2内，便于实现喷管2的顺畅进水。
由此，进水结构1将对喷管2的进水功能与驱动功能集成在一起，不仅可以避免进水结构1在喷管2转动过程中发生干涉，保证此种类型的喷管2可以正常进水、正常转动，而且可以使洗碗机的内部结构更加地合理紧凑，提高洗碗机内部的空间利用率，从而便于控制洗碗机的体积，减小洗碗机的占用空间。
并且，通过外壳400和配水件100可以对过水管220进行安装定位，保证过水管220的装配可靠性和稳定性。通过设置卡接件500既可以对过水管220进行限位，又可 以对支撑件600进行限位，换言之，通过设置一个卡接件500即可实现对支撑件600和过水管220的限位。这样可以减少进水结构1的零件个数，省去对支撑件600和过水管220分别单独设置限位结构件，便于使进水结构1的设计和制造更加简单，便于减小进水结构1的占用空间，使进水结构1更加地小巧紧凑，还便于减小进水阻力，提高进水结构1的进水压力，降低进水结构1的成本。因此，根据本申请实施例的喷臂组件的进水结构1能够通过过水管220向喷管2进水并带动喷管2转动，具有结构紧凑可靠等优点。
下面参考附图描述根据本申请具体实施例的喷臂组件的进水结构1。
在本申请的一些具体实施例中，如图1-图15所示，根据本申请实施例的喷臂组件的进水结构1包括配水件100、过水管220、外壳400、卡接件500和支撑件600。
可选地，在一些示例中，支撑件600可以为轴承，例如支撑件600可以为滚珠轴承，滚珠轴承是滚动轴承的一种，可以包括滚珠、内环、外环与保持器。滚珠可以为球形合金钢珠，内环可以为钢圈，外环可以为钢圈。将球形合金钢珠安装在内钢圈和外钢圈的中间，以滚动方式来降低动力传递过程中的摩擦力和提高机械动力的传递效率。也就是说，支撑件可以为滚珠轴承，通过滚珠的滚动实现过水管220与外壳400的相对转动。
当然，在另一些示例中，轴承600也可以由塑料的圆环结构代替。
在本申请的一些实施例中，如图8-10所示，过水通道201可以形成在过水管220内且沿过水管220的轴向延伸，卡接件500可以与过水管220卡接相连，这样在过水管220的轴向上，卡接件500可以分别对过水管220和支撑件600进行限位。这样利用卡接件500可以提高过水管220的设置可靠性，避免过水管220与配水件100脱离配合，同时利用卡接件500可以提高支撑件600的设置可靠性，避免支撑件600与外壳400脱离配合，以便于保证进水结构1的工作性能。
这里需要理解的是，卡接件500可以在过水管220的轴向上的一个方向对过水管220进行限位，也可以在过水管220的轴向上的两个方向均对过水管220进行限位，对支撑件600的限位亦同理。例如，过水管220的轴向沿前后方向延伸，卡接件500可以在前后方向上均对过水管220进行限位，以防止过水管220向前移动和向后移动。
具体地，如图9所示，过水管220的外周面可以具有卡接槽202，卡接件500大体为环形，卡接件500适于套设在过水管220的外周壁，卡接件500设有卡接凸起510，卡接凸起510适于配合在卡接槽202内，这样可以限制过水管220向远离配水件100的方向移动。例如，配水件100设在过水管220的后方，卡接件500可以限制过水管220向前移动。这样可以防止过水管220由于水的冲击力而从配水件100脱落出来。
更为具体地，卡接槽202可以为一个或多个，卡接凸起510可以为一个或对个，卡接凸起510可以一一对应配合在对应的卡接槽202内。
可选地，如图9所示，卡接件500可以与支撑件600朝向配水件100的一侧端面进行接触配合，这样可以限制支撑件600脱离配合槽402。例如，卡接件500设在支撑件600的后方，卡接件500的前端可以与支撑件600的后端面进行接触配合，这样可以限制支撑件600向后移动，防止支撑件600发生移动而脱离配合槽402。这样便于实现卡接件500对支撑件600的可靠限位，提高支撑件600的装配稳定性和可靠性。
在一些实施例中，如图2所示，配水件100可以具有第一配合面110，第一配合面110可以为平面，出水口102形成于第一配合面110，过水管220轴向上的一端适于与第一配合面110接触配合且另一端适于与喷管2传动连接。这样不仅便于对过水管220进行定位，实现过水管220与配水件100之间的可靠配合，而且便于对过水管220与配水件100的连接处进行有效密封，保证过水管220与配水件100之间形成密封可靠的水流通道。
举例而言，配水件100固定设在洗碗机的洗涤腔的后侧壁上(前后方向如图2所示，这里需要理解的是，前后方向的限定仅为了便于结构的描述，并不是对本申请中洗碗机内结构实际设置方向的限制)，配水件100大体沿竖直方向延伸，配水件100朝向过水管220的一侧具有配水接头，配水接头的前侧具有第一配合面110，第一配合面110为竖直延伸的平面，出水口102形成在第一配合面110上。过水管220具有过水管220，过水管220的后端的端面与第一配合面110接触配合，过水管220的前端与喷管2传动连接。其中，喷管2可以为圆管，喷管2可以为多个，多个喷管2在洗涤腔内沿前后方向延伸且沿左右方向间隔设置(左右方向如图3所示，这里需要理解的是，左右方向的限定仅为了便于结构的描述，并不是对本申请中洗碗机内结构实际设置方向的限制)。过水管220可以为圆管，过水管220内可以形成有在过水管220的轴向两侧开口的过水通道201，以使过水管220能够分别连通配水件100和喷管2。这样不仅便于对过水管220进行定位，实现过水管220与配水件100之间的可靠配合，而且便于对过水管220与配水件100的连接处进行有效密封，保证过水管220与配水件100之间形成密封可靠的水流通道。
具体地，如图2所示，进水结构1还可以包括第一密封件130，第一配合面110可以设有朝向过水管220延伸的配合套筒120，配合套筒120的内周壁与过水管220的外周壁间隔设置，配合套筒120的内周壁与过水管220的外周壁之间可以设有第一密封件130。这样通过设置配合套筒120，可以对过水管220的装配进行定位和导向，便于过水管220的准确安装。而且，可以形成第一密封件130的设置空间，保证第一密封 件130的设置可靠性，从而便于利用第一密封件130密封过水管220与配水件100之间的连接处，提高密封效果，避免发生水的泄漏。
举例而言，第一配合面110可以设有向前方延伸的配合套筒120，配合套筒120的后端与第一配合面110相连，配合套筒120的前端形成开口。过水管220适于通过该开口配合安装在配合套筒120内，且配合套筒120与过水管220间隔设置。进一步地，配合套筒120可以包括直筒段和与直筒段相连的外扩段，外扩段的横截面积大于直筒段的横截面积，外扩段位于直筒段的前方。第一密封件130可拆卸地设在直筒段内，第一密封件130形成为封闭的密封环，密封环套设在过水管220的外侧，在安装完成后，密封环的内周面适于与过水管220压紧配合，且密封环的外周面适于与直筒段的内周壁压紧配合。
在一些实施例中，如图3所示，齿轮部件200可以包括驱动件210和过水管220，驱动件210用于与上级传动件进行传动配合，过水管220与驱动件210相连，过水通道201形成于过水管220内。这里需要理解的是，驱动件210和过水管220可以是独立的两个结构件，也可以为一体成型的一个整体件。这样不仅可以利用过水管220传递动力，以带动喷管2进行转动，而且可以利用过水管220向喷管2提供进水，保证喷管2可以正常工作。
举例而言，驱动件210和过水管220一体成型为从动齿轮件，上级传动件可以形成为主动齿轮件。从动齿轮件包括驱动件210和过水管220，驱动件210的外边沿形成有从动齿，驱动件210可以通过从动齿与主动齿轮件传动相连，驱动件210的中部具有沿厚度方向贯通的过孔，过水管220可以穿设在该过孔内，过水管220内形成有过水通道201，过水通道201连通配水件100和喷管2。这样不仅可以利用过水管220传递动力，以带动喷管2进行转动，而且可以利用过水管220向喷管2提供进水，保证喷管2可以正常工作。
具体地，如图2所示，卡接件500为环形卡板，配合槽402朝向配水件100的一侧具有开口，环形卡板的内端形成为卡接凸起510，环形卡板的外端适于与外壳400接触配合。这样可以对卡接件500进行定位，便于实现过水管220与卡接件500的卡接配合，便于提高装配效率和连接强度。
举例而言，过水管220的外周面具有沿周向延伸的环形的卡接槽202，卡接件500可以形成为环形卡板，环形卡板具有沿环形卡板的轴向贯通的缺口，环形卡板能够发生弹性变形。在环形卡板安装完成后，环形卡板可以箍住过水管220的外周面，实现环形卡板与过水管220之间的可靠连接。进一步地，环形卡板在径向上的内端适于配合在卡接槽202内，环形卡板在径向上的外端适于与外壳400搭接配合，以对过水管 220的轴向进行限位。这样可以对卡接件500进行定位，便于实现过水管220与卡接件500的卡接配合，便于提高装配效率和连接强度。
在本申请的另一些实施例中，如图10所示，进水结构1还可以包括固定盖700，固定盖700可以分别与配水件100和外壳400固定连接，固定盖700可以具有限位孔710，过水管220适于穿设在该限位孔710内。例如，进水结构1还可以包括固定盖700，固定盖700与外壳400通过旋扣结构固定在一起，固定盖700与配水件100卡接固定在一起。固定盖700可以形成有限位孔710，过水管220适于穿设在该限位孔710内。这样可以利用固定盖700对过水管220进行限位，可以防止过水管220发生晃动，提高过水管220的可靠性寿命。
具体地，如图10所示，固定盖700、外壳400和过水管220可以限定出安装腔720，卡接件500可以设在安装腔720内。这样便于连接件的安装设置。
更为具体地，如图10所示，安装腔720内可以设有第二密封件730，第二密封件730适于夹持在过水管220与固定盖700之间，固定盖700可以具有容纳槽740，容纳槽740内可以设有第三密封件750，第三密封件750适于夹持在固定盖700与配水件100之间。由此，通过设置第二密封件730，可以防止洗涤水进入支撑件600。由于洗涤水有些脏污，时间久了以后，支撑件600外壳400内表面会积渣，影响支撑件600玻璃球转动，而造成支撑件600可靠性下降。同时，通过设置第三密封件750可以放置洗涤水从固定盖700与配水件100的连接处漏出。
可选地，如图10所示，卡接件500可以为拉环，拉环可以设有限位凸台，过水管220的外周面可以设有与限位凸台配合限位的限位配合凸台221，限位凸台可以与卡接凸起510在拉环的轴向上间隔设置。这样通过过水管220与卡接件500之间的配合关系，可以限制过水管220向靠近配水管或远离配水管的方向移动，进一步便于提高过水管220的设置准确性和稳定性。这里需要理解的是，拉环能够发生弹性变形。在拉环安装完后，拉环可以箍住过水管220的外周面。
在一些具体示例中，固定盖700可以与外壳400通过旋扣结构固定在一起，第二密封件730装在固定盖700的另一端，最后固定盖700可以与配水件100通过扣位固定。第二密封件730的作用是防止洗涤水进入支撑件600，洗涤水有些脏污，时间久了以后，支撑件600外壳400内表面会积渣，影响支撑件600玻璃球转动，造成支撑件600可靠性下降。同时增加固定盖700的作用是可以防止过水管220发生晃动，提高过水管220的可靠性寿命。
具体地，过水管220的转动轴线沿过水管220的轴向延伸。换言之，过水管220的转动轴线沿过水管220的长度方向延伸，即过水管220沿着其中心轴线转动。这样 过水管220可以驱动喷管2沿过水管220的轴向进行转动。
更为具体地，喷管2可以沿着其中心轴线转动，即喷管2的转动轴线沿喷管2的长度方向延伸，喷管2长度方向上的一端与过水管220的一端相连，过水管220带动喷管2一起转动，喷管2的转动轴线与过水管220的转动轴线重合。
举例而言，过水管220为圆管，过水管220的轴向沿前后方向设置，过水管220的转动轴线也沿前后方向延伸。喷管2为圆管，喷管2的轴向沿前后方向设置，喷管2的转动轴线也沿前后方向延伸。喷管2轴向上的后端与过水管220的前端相连，过水管220带动喷管2同步进行转动，喷管2的转动轴线与过水管220的转动轴线重合。
