Description

洗衣机的溢水排气组件和具有其的壁挂式洗衣机 技术领域
本发明涉及洗衣机制造技术领域，更具体地涉及一种洗衣机的溢水排气组件和具有其的壁挂式洗衣机。
背景技术
现有技术中，滚筒洗衣机在工作时由于内桶的旋转或者后外桶内洗涤剂投放过量导致洗涤泡沫过多，往往会在洗衣机的后外桶内产生一定压力，使得后外桶内气压与外界气压不平衡，从而带来一定的安全隐患，而且，在洗衣机工作初始阶段时，若洗衣机控制组件发生不良导致后外桶内进水不止，这也会造成后外桶内水位过高且无法及时排出，进而导致泄露可能。
为了防止滚筒洗衣机内的泡沫溢出从而污染墙壁及地面，现有技术存在一种洗衣机，如中国专利文献CN106120231A，其揭示了一种壁装式滚筒洗衣机，如该专利中的图1所示，其通过排气孔281设置一泡沫排放管282，并将泡沫排放管282引入下水管278，同时在泡沫排放管282上设置通气管296并保持通气管296的上端高于与泡沫排放管282连接处，用于保持洗衣机后外桶内的气压稳定，洗衣机运转时，后外桶内的泡沫经过泡沫排放管282排除；从而，中国专利文献CN106120231A揭示的技术方案能够在一定程度上防止泡沫溢出。
然而，中国专利文献CN106120231A揭示的技术方案中，泡沫经由泡沫排放管282排放时会进入通气管296，虽然本方案中通气管296的上端向上延伸，但由于洗衣机后壁上端的空间有限，无法为泡沫提供较长的行走路径，因此，当泡沫量较多时，依然会有部分泡沫从通气管296的上端出口排出，从而污染墙壁。因此，中国专利文献CN106120231A揭示的技术方案依然存在排泡能力较弱的缺陷。
发明内容
本发明旨在至少解决现有洗衣机排除泡沫能力较弱的缺陷，从而提出一种洗衣机的溢水排气组件，用于防止洗衣机桶内泡沫的溢出洗衣机外部而污染墙体。
本发明还提出了一种具有上述溢水排气组件的壁挂式洗衣机。

可选地，所述第一排气管与所述第二排气管之间一体成型。
根据本发明的一个实施例，所述溢水管包括第一溢水管和第二溢水管，所述第一溢水管的一端适于连接至洗衣机的后外桶，所述溢水排气组件还包括三通管，所述三通管具有第一端口、第二端口和第三端口，所述第一端口与所述第一溢水管的另一端 连通，所述第二端口与所述第二溢水管连通，所述第三端口与所述排气组件的一端连通。

下面参考附图描述根据本发明实施例的洗衣机的溢水排气组件100，该溢水排气组件100可以应用于壁挂式洗衣机。
如图1-图14所示，根据本发明一个实施例的洗衣机的溢水排气组件100包括溢水管10和排气组件20。
溢水管10的一端适于与洗衣机的桶体后外桶400相连，溢水管10的另一端与外部导通，这样，洗衣机的桶体后外桶400通过溢水管10与外部形成流通路径，在洗衣机桶体后外桶400内的水位过高或者泡沫过多时，泡沫和水能够通过溢水管10所形成的流通路径排出。
排气组件20形成为折弯状结构具设有一弯折结构，排气组件20的一侧连接至溢 水管10，并且排气组件20与溢水管10相连的一侧的管段弯折结构在上下方向上不低于排气组件20与溢水管10连接处，也就是说，溢水管10与排气组件20的连接处在上下方向上不高于弯折结构所在的位置与溢水管10直接相连的排气组件20的管段。，这样，后外桶400内的溢出水不会通过溢水管10进入排气组件20，从而保证排气组件20内的流通路径畅通。
当洗衣机的后外桶400内泡沫过多，并且溢水管路的流通路径过长时，会导致泡沫的流动阻力也随之增大，部分泡沫来不及排出时，进而会进入与溢水管10直接相连的排气组件20的一侧管段中，随后慢慢上升至弯折结构，并且弯折结构内受到挤压大部分破裂，同时，少量泡沫可能会通过弯折结构继续进入排气组件20的另一侧管段(即位于排气组件20的弯折结构的另一侧)，此时，溢水管10中的泡沫已经排出至外部，这时会在排气组件20内形成负压，在虹吸作用下，泡沫会瞬间回流至溢水管10中，进而排出至外部。
根据本发明实施例的洗衣机的溢水排气组件100，通过设置与溢水管10相连的折弯状且具有弯折结构的排气组件20，并且将排气组件20与溢水管10相连的弯折结构一侧管段设置为在上下方向上不低于所述溢水管10与所述排气组件20的连接处，由此，从洗衣机后外桶400中排出的过量的泡沫，在进入排气组件20后，逐渐上升至弯折结构气管转接件23，并在弯折结构气管转接件23处大量破裂，达到灭泡效果，而后从而既可以在后外桶400内外形成气压平衡，又可以避免后外桶400内的泡沫溢出而造成洗衣机的外部污染。
如图1所示，根据本发明的一个实施例，排气组件20主要由第一排气管21和第二排气管22组成，第一排气管21的一端与溢水管10相连，并且大致沿竖直方向(如图1所示的上下方向)向上延伸，第二排气管22的一端与第一排气管21的另一端相连，第二排气管22的另一端向下延伸形成与外部导通的排气端24，并且第一排气管21与第二排气管22连接处形成为呈折弯状的弯折结构。
具体地，当洗衣机后外桶400内的泡沫由于流动阻力增大而来不及排出时，部分会进入第一排气管21中，然后慢慢上升至弯折结构气管转接件23内，并在弯折结构气管转接件23内由于受到内壁面挤压大部分破裂，从而达到灭泡的效果，即使少量泡沫可能会继续进入第二排气管22中，但是由于此时溢水管10中的泡沫和水已经排出至外部，此时，第一排气管21和第二排气管22中形成负压，在虹吸作用下，泡沫会瞬间回流至溢水管10中，进而排出至外部。
如图8-图11，在本发明的一个示例中，弯折结构可以为气管转接件23，第一排气管21与第二排气管22之间通过气管转接件23连接，这样进入第一排气管21中的泡沫，会在流通至气管转接件23时受到其内壁面的挤压而大量破裂，这样既可以达到灭 泡效果，又可以平衡后外桶400的气压。
如图8-图11，在本发明的进一步示例中，气管转接件23大致形成为“人”字形结构，气管转接件23主要由第一连接部231、第二连接部232和灭泡部233组成，灭泡部233位于第一连接部231和第二连接部232的上方，第一连接部231与第一排气管21的上端连通，第二排气管232与第二排气管22的上端连通，第一排气管231、第二排气管232、灭泡部233相互连通，这样，进入第一排气管21的泡沫上升至第一连接部231后，会逐渐进入灭泡部233，并且在灭泡部233内受到内壁的挤压而破裂，从而达到灭泡的效果，即使有部分泡沫未破裂而进入第二连接部233，进而进入第二排气管22内，但是由于此时溢水管10中的泡沫和水已经排出至外部，此时，第一排气管21和第二排气管22中形成负压，在虹吸作用下，泡沫会瞬间回流至溢水管10中，进而排出至外部。
如图10和图11所示，在进一步的示例中，灭泡部233的顶部密封，这样可以在灭泡沫能形成泡沫挤压腔，从而增强对进入其中的泡沫的挤压作用，提高灭泡效果。
如图1、图8-图11所示，根据本发明的一个可选示例，气管转接件23的内径小于第一排气管21的内径，这样可以保证泡沫从第一排气管21中进入气管转接件23时，泡沫可以更多的破裂，同时，气管转接件23的内径小于第二排气管22，这样部分继续进入第二排气管22的泡沫可以在第二排气管22内逐渐破裂，避免泡沫通过第二排气管22流出机体外。当然，第一排气管21和第二排气管22的具体内径可以根据实际设计需要进行调整，只要满足二者均小于气管转接件23即可。
根据本发明的又一个可选示例，第二排气管22的排气端24在上下方向低于溢水管10与第一排气管21连接处，这样可以增长流通路径，保证泡沫在流通路径内逐渐破裂，避免泡沫通过第二排气管22流出至洗衣机外，影响使用。
如图12、图13和图14所示，在本发明的另一个实施例中，排气组件20包括第一排气管21和第二排气管(未示出)，第一排气管21的一端与溢水管10相连，并且大致沿竖直方向(如图1所示的上下方向)向上延伸，第二排气管的一端与第一排气管21的另一端相连，第二排气管的另一端开放形成排气端，第二排气管被构造成弯折结构，例如，第二排气管可以形成沿周向延伸的弧形或者环形，这样，可以延长流通路径，保证泡沫在流通路径内逐渐破裂，避免泡沫流出至洗衣机外，影响使用。
在一些示例中，为便于制造、装配，提高第一排气管21与第二排气管之间的密闭性，第一排气管21与第二排气管之间可以一体成型。
如图1、图3和图4所示，在本发明的一个实施例，溢水管10主要有第一溢水管11、第二溢水管12和三通管30组成，三通管30包括第一端口、第二端口和第三端口， 第一溢水管11的上端与洗衣机的后外桶400相连，第一溢水管11的下端连接至第一端口，第二溢水管12的上端连接至第二端口，第二溢水管12的下端与外部导通，同时，排气组件20通过第三端口与溢水管10导通，这样，可以便于溢水排气组件100装配连接，简化制造工艺。
在本发明的一个示例中，为了便于制造、装配，第一溢水管11、第二溢水管12的内径相等，而第一排气管21与第二排气管22的内径相等，这样，在组装时，可以增强溢水管10之间以及排气管之间的互换性。
根据本发明的一个示例，为避免后外桶400内泡沫过多，导致泡沫来不及从溢水管10排出，进而通过排气组件20的流通路径从排气管的出口端排出，将溢水管10(包括第一溢水管11和第二溢水管12)的内径D1设置为大于排气管(包括第一排气管21和第二排气管22)的内径D2，由此，可以增大溢水管10内流通路径内的容量，从而减少进入排气管内的泡沫。当然，本领域技术人员也可以根据实际设计需要仅延长排气管的长度，或将溢水管10的内径D1设置为大于或等于排气管的内径D2的同时，延长排气管的长度，以上的示例均可以达到避免泡沫从排气组件20的排气端24流出至洗衣机外的目的。
如图2和图4，根据本发明的一个实施例，溢水排气组件100还包括紧固单元40，例如，如图3中所示的上紧固单元40和下紧固单元40，上紧固单元40将溢水管10与洗衣机的后外桶400固定连接，下紧固单元40将溢水管10与洗衣机的排水组件200固定连接。
如图2，在本发明进一步的示例，所述紧固单元40主要由紧固本体41和扣合结构42组成，紧固本体41大致形成为卡箍，套设在溢水管10与桶体后外桶400的连接处或者溢水管10与排水组件200的连接处，扣合结构42设在环状紧固本体41的两端，通过扣合结构42的配合作用，可以将紧固本体41卡紧在溢水管10上，从而保证溢水管10与桶体后外桶400和排水组件200之间的连接可靠性，增强密闭性。
在本发明的一个具体示例中，为保证溢水管10以及排气管的固定稳定，所述洗衣机的溢水排气组件100还包括多个管夹110，例如，管夹110的数量可以是3个，5个，也可以是其他多个，多个管夹110沿溢水管10以及排气管的长度方向(如图4所示)间隔开设置在洗衣机的固定板300的背侧上，由此，实现对溢水管10及排气管的限位，避免溢水管10及排气管脱离固定板300，影响溢水排气组件100的排水排沫、以及平衡气压的功能。

如图4-图7所示，根据本发明实施例的壁挂式洗衣机包括固定板300、后外桶400、连接部500和根据本发明实施例所述的溢水排气组件100。
后外桶400安装在固定板300的正侧(即如图6所示的前侧)，后外桶400的上端设有通孔410，固定板300上设有贯通的安装孔，连接部500穿设在安装孔中且连接部500的前端与通孔410导通，连接部500的后端与溢水排气组件100相连。
根据本发明实施例的壁挂式洗衣机，通过利用根据本发明上述实施例的溢水排气组件100，具有结构简单、安全可靠、能够实现后外桶400内外气压平衡等特点。
根据本发明的一个实施例，如图6和图7所示，连接部500大致形成为圆柱，连接部500的前端与通孔410之间圆滑过渡，这样可以更好地将水或泡沫引入溢水管10中，连接部500的后端设有凸起单元510，所述凸起单元510可以是圆柱端部向周侧延伸凸起形成，这样，可以避免溢水管10连接后从连接部500上脱落。
如图15和图16，在一些示例中，所述壁挂式洗衣机具有箱体组件600，箱体组件600的尺寸大于固定板300的尺寸，这样可以使得箱体组件600至少部分可以覆盖固定板300的边沿最外端，也就是说，箱体组件600在上下方向上的高度略大于固定板300在上下方向上的高度，在左右方向上的宽度略大于固定板300在左右方向上的宽度，并且，箱体组件600罩设在固定板300的周向外侧时，与固定板300的外侧边沿能够部分或者全部止抵。这样，在安装与或拆卸墙体上，可以为用户提供施力点，方便操作。
如图15所示，在一些示例中，箱体组件600包括前壳体620，前壳体620连接至后外桶400上且限定出腔室601，前壳体620和后外桶400的左侧和右侧分别设有至少一组左右方向的限位机构。如图15和图16所示，前壳体620大体为与固定板300相适配的腔体结构，该腔体结构的前后方向敞开，这样，前壳体620在装配过程中，后外桶400和固定板300整体可以由后向前伸入前壳体620内或前壳体620由前向后套设于后外桶400的外侧从而限定出用于清洗衣物的腔室601，其中，前壳体620的前侧设有用于打开或关闭腔室601的门体(图未示出)。
前壳体620和固定板300的左侧和右侧可以同时设有一组以上的限制前壳体620和固定板300左右方向偏移的限位机构，例如，在前壳体620和固定板300的前后方向的左侧和右侧可以分别设有一组以上的限位机构；或者在前壳体620和固定板300的上下方向的左侧和右侧可以分别设有一组以上的限位机构；或者在前壳体620和固定板300的前后方向和上下方向的左侧和右侧可以分别设有一组以上的限位机构，从而有效地限定前壳体620和固定板300在左右方向的自由度，避免前壳体620和固定板300在使用期间发生位置偏移而导致结构变形或损坏，进而有效提高整个壁挂式洗衣机的箱体组件600的使用寿命。
在本发明的一些实施例中，每组限位机构可以包括：固定座630和限位结构640。具体地，固定座630设在前壳体620的侧壁或固定板300侧边的其中一个上。限位结构640设在前壳体620的侧壁或固定板300侧边的另一个上，且限位结构640适于与固定座630相 配合固定。
也就是说，固定座630和限位结构640的设置位置并不受特别限制，当固定座630设在前壳体620上时，对应的与之配合的限位结构640则可以设在固定板300的侧边上；当固定座630设在固定板300的侧边上时，对应的与之配合的限位结构640可以则设在前壳体620的侧壁上。当然，固定座630或限位结构640可以同时设在前壳体620的侧壁和固定板300侧边上。由此，进一步提高前壳体620和后外桶400的之间装配的稳定性。
在本发明一些可选实施例中，限位结构640包括：限位部641和连接段642。限位部641通过连接段642连接于前壳体620或固定板300侧边。例如，如图20所示，限位结构640为大头螺钉，大头螺钉的大头部为限位部641，大头螺钉的螺杆部为连接段642。大头螺钉的螺杆部与固定板300通过螺纹方式配合从而将大头螺钉连接于固定板300侧边上。当然，可以理解的是，上述描述仅是示意性的，并不是对本发明保护范围的限制，大头螺钉可以通过卡设方式连接于固定板300上。
一些示例中，参照图20、图21结合图15和图18，固定座630内具有固定腔室631，固定腔室631具有阻挡侧壁633，限位部641适于插入固定腔室631内并被阻挡侧壁633限位。即限位部641嵌入于固定腔室631内，阻碍前壳体620和固定板300之间发生左右位置偏移，由此，进一步提高前壳体620和后外桶400之间配合的稳定性，提高壁挂式洗衣机的箱体组件600的使用寿命。
在本发明的一个具体实施例中，如图15结合图20所示，固定座630设在前壳体620的侧壁后部且固定座630的后侧敞开，限位结构640设于固定板300侧边，限位结构640的限位部适于从固定座630的后侧进入固定腔室631。限位结构640为垂直于固定板300侧边并连接的大头螺钉，大头螺钉的大头部与固定板300侧边之间设有容纳阻挡侧壁633的间隙。
具体地，如图15和图20所示，所示，大头螺钉可以包括呈伞状的大头部和一端与大头部连接的螺杆部，螺杆部与固定板300的连接固定，大头部可以顺着伞状的弧形面嵌入固定座630的固定腔室631内，当大头部落入固定腔室631内之后将被卡设于固定腔室631内，且阻挡侧壁633卡设于间隙内，从而实现固定板300与前壳体620的之间的稳定配合，避免前壳体620和固定板300在左右方向发生位置偏移。
在本发明的另一些实施例中，阻挡侧壁633上成型有适于大头螺钉的螺杆部通过的避让缺口。具体地，如图15和图20所示，固定座630设在前壳体620的侧壁后部且后侧敞开，在固定座630的与前壳体620侧壁相对的侧壁上形成有避让缺口632，其中大头螺钉从避让缺口632进入固定腔室631内。换言之，固定座630朝向固定板300的侧壁由后向前方向凹陷形成固定腔室631，且固定座630的内侧壁(固定座630靠近前壳体620中心 的一侧)形成避让缺口632，大头螺钉设在固定板300的侧壁上且沿固定板300的左右方向延伸。这样，前壳体620与固定板300配合时，大头螺钉穿设避让缺口632的开口端伸入固定腔室631并由后向后方向移动卡入固定腔室631内。
进一步地，如图17所示，避让缺口632可以包括：弧形段6321和两个倾斜段6322。具体地，弧形段6321的形状适于与大头螺钉的螺杆部形状匹配。两个倾斜段6322分别从弧形段6321的两端分别倾斜地向外延伸。换言之，避让缺口632从后向前宽度逐渐增加，由此，便于大头螺钉嵌入固定腔室631内，且避免大头螺钉从固定腔室631内脱离，有效提高前壳体620和固定板300之间装配的稳定性。
在本发明再一些实施例中，固定板300的顶部具有固定舌311，固定舌311上具有螺钉孔，前壳体620的顶壁后侧具有定位孔621，前壳体620与固定板300连接后定位孔621与螺钉孔重合以适于穿过螺钉。如图15-图16结合图18-图19所示，后外桶400和固定板300伸入前壳体620内后，前壳体620的顶部盖设于固定板300的顶壁，定位孔621和螺钉孔在上下方向相对设置，螺钉穿设定位孔621和螺钉孔从而在上下方向限定前壳体620和固定板300的自由度，由此，进一步提高前壳体620和固定板300之间装配的稳定性，避免前壳体620和固定板300上下方向发生位移，提高壁挂式洗衣机的箱体组件600的使用寿命。有利地，螺钉的正上方可以设有孔贴，由此，提高壁挂式洗衣机的箱体组件600的外观质量。
下面参照图15-图20详细描述根据本发明一个具体实施例的壁挂式洗衣机。
具体地，前壳体620连接至固定板300上且限定出腔室601，前壳体620和固定板300上下方向的左侧和右侧分别设有多组限制前壳体620和固定板300左右方向偏移的限位机构。
限位机构可以包括固定座630和限位结构640。固定座630设在前壳体620的侧壁后部且后侧敞开以形成固定腔室631，固定腔室631具有阻挡侧壁633，限位部641适于插入所述固定腔室631内并被阻挡侧壁633阻挡限位。在固定座630的与前壳体620侧壁相对的侧壁上形成有避让缺口632。限位结构640沿固定板300的左右方向设在固定板300上。其中，限位结构640可以为大头螺钉，大头螺钉从避让缺口632进入固定腔室631内。大头螺钉与固定板300的侧边通过螺纹方式配合，且在大头螺钉的大头部与固定板300侧边之间设有容纳阻挡侧壁633的间隙。
进一步地，避让缺口632包括：弧形段6321和两个倾斜段6322。弧形段6321的形状适于与大头螺钉的螺杆部形状匹配。两个倾斜段6322分别从弧形段6321的两端分别倾斜地向外延伸。即避让缺口632从后向前宽度逐渐增加，由此，便于大头螺钉嵌入固定腔室631内，此时，阻挡侧壁卡入大头螺钉的大头部与固定板300之间的间隙内，从而避免大 头螺钉从固定腔室631内脱离，有效提高前壳体620和固定板300之间装配的稳定性。
固定板300的顶部具有固定舌311，固定舌311上具有螺钉孔，前壳体620的顶壁后侧具有定位孔621，前壳体620与固定板300连接后定位孔621与螺钉孔重合以适于穿过螺钉。螺钉穿设定位孔621和螺钉孔从而在上下方向限定前壳体620和固定板300的自由度，由此，进一步提高前壳体620和固定板300之间装配的稳定性，避免前壳体620和固定板300发生位移，提高箱体组件600的使用寿命。
上述具体实施例的壁挂式洗衣机的装配过程大致如下：首先将大头螺钉的螺杆部安装设置于固定板300上；接着沿着前后方向将固定板300和后外桶400向前壳体620方向移动使得固定板300和后外桶400伸入前壳体620内，大头螺钉卡设于固定腔室631内使得前壳体620和固定板300在左右方向稳定配合；最后将螺钉穿过定位孔621和螺钉孔使得前壳体620和固定板300在上下方向进一步稳定配合。
