Description

一种滚筒洗衣机 技术领域
本发明属于衣物处理设备技术领域，具体地说，涉及一种滚筒洗衣机。
背景技术
现有的滚筒洗衣机都设有窗垫，窗垫用于连接洗衣机的前面板开口和外筒开口以保证洗衣机的密封性。在洗涤衣物时，外筒会产生振动位移，为防止洗衣机损坏，窗垫由柔性材料制成且形成有褶皱结构，利用褶皱结构的形变减轻外筒的晃动对箱体的影响，同时还能增强窗垫的抗拉能力。
然而在洗涤过程中，洗涤水会进入到窗垫的褶皱部内，并会存积在该褶皱部的下部区域，在重力的作用下，洗涤水中附着的脏污颗粒会沉淀并积聚在该区域内，而由于褶皱部内积存的洗涤水几乎处于静止状态，长此以往会形成顽固污垢，并且由于污垢位于褶皱部内，十分不便于清理，且易滋生细菌，影响洗衣机的内部清洁效果，不利于消费者健康。
申请号为201821425036.4的中国专利公开了一种洗衣机窗垫及滚筒洗衣机，该洗衣机窗垫包括与洗衣机的前面板连接的外唇以及与所述洗衣机的外筒连接的内唇，所述外唇与所述内唇之间形成筒状的窗垫主体，所述窗垫主体为可伸缩的褶皱结构，所述褶皱结构包括多阶连续设置的台阶。窗垫主体靠近外唇的部分高度较高，靠近内唇的部分高度较低，进入褶皱结构内的洗涤水会在自身重力作用下向外筒内流动，从而减少褶皱结构内的洗涤水残留，进而减少褶皱结构内残留的杂物。
上述申请通过将窗垫主体靠近内唇的部分高度设置的相对较低一些，能够使得褶皱结构内的部分洗涤水在重力的作用下向流向外筒内，但是并不能将褶皱结构内积存的洗涤水全部排尽，褶皱结构的底部仍会积存少量的残水，长时间会形成顽固污垢，不易清理，滋生细菌，影响洗衣机的清洁效果。
有鉴于此，特提出本发明。

下面结合实施例对本发明进行进一步地详细的说明。
如图1至图6所示，本发明实施例中提供了一种滚筒洗衣机包括箱体和设置在箱体内的外筒1、以及安装在外筒1筒口处的窗垫2，所述窗垫2密封连接在外筒1筒口与箱体之间，避免滚筒洗衣机工作时，洗涤水进入壳体与外筒1之间。需要说明的是本实施例中附图的外筒1仅示意出外筒的前半截筒，并未示意出后半截筒。
如图1和图2所示，所述窗垫2包括采用柔性材料制成的呈筒状的窗垫本体，所述窗垫本体的周向设置有向外凸出的褶皱部21，通过设置的褶皱部21形变减轻外筒1的晃动对箱体的影响，同时还能增强窗垫2的抗拉能力。所述褶皱部21内形成有环形腔210，所述窗垫2和外筒1之间设置有连通所述环形腔210和外筒1内部的残水引导结构3。
本发明实施例通过在窗垫2和外筒1之间设置的残水引导结构3，将环形腔210底部积存的残水全部引导至外筒1内，避免残水长时间积存在褶皱部21内形成顽固污垢，不易清理，滋生细菌，影响洗衣机的清洁效果。并且本发明将窗垫2内积存的残水直接引导至外筒1内，随着洗衣机排水一并排出，无需额外增设排水结构，简化洗衣机的结构，提升用户使用体验。
如图4和图5所示，所述褶皱部21的底部位置设有与环形腔210相连通的排残水口211，所述外筒1的桶壁上设有入水口101，所述入水口101的高度等于或低于所述排残水口211，所述残水引导结构3为连接在排残水口211和入水口101之间的残水引导管路。通过将所述排残水口211的高度高于或等于入水口101，使得褶皱部21底部积存的残水在重力的作用下由所述残水引导管路流入到外筒1内，随着外筒1排水一并排出到洗衣机外部，排水方式方便快捷。
本发明实施例中所提供的残水引导结构3为直接连通环形腔210和外筒1的采用残水引导管路，通过入水口101和排残水口211相对高度的设置，环形腔210内的残水在重力的作用通过所述残水引导管路直接引导至外筒1内，结构简单，且能够将环形腔210内的残水全部排尽，排残水效果更好。
如图1至图5所示，本实施例中，所述残水引导管路包括第一引导管31和第二引导管32，所述第一引导管31的第一端与排残水口211连接，第二引导管32的第一端与入水口101连接，所述第一引导管31的第二端和第二引导管32的第二端相配合连接。
优选地，所述第一引导管31的第二端和第二引导管32的第二端相搭接配合，所述第一引导管31和第二引导管32的长度之和大于所述排残水口211和入水口101之间的距离，第一引导管31和第二引导管32的第二端至少部分重合搭接设置。
本发明通过采用上述方案，相比与第一引导管31的第二端和第二引导管32的第二端边沿直接连接固定，残水引导管路整体的适配性更高。
由于不同型号、容量的洗衣机外筒1和窗垫2设置的相对位置可能会有所变化，导致排残水口211和入水口101之间的距离远近不一。而本发明通过采用第一引导管31和第二引导管32的第二端至少部分重合配合设置的方案，无需设置不同长度的残水引导管路，通过调整第一引导管31和第二引导管32搭接重合部分的长度实现的不同距离的排残水口211和入水口101之间的连接，通用性、容错率更高。第 一引导管31和第二引导管32的长度均可采用同一尺寸、长度，加工更方便快捷，降低了模具成本。
优选地，本发明实施例中所述第一引导管31为采用弹性材料制成的弹性胶管，所述第一引导管31为采用硬质材料制成的插接管，所述插接管一端固定连接在所述入水口101处，另一端过盈插接配合在所述弹性胶管内。插接管的端部过盈插接配合在弹性胶管内，在实现第一引导管31和第二引导管32的导通，能够形成良好的密封效果，有效地避免残水泄露的问题。
在上述方案中，所述插接管的外径大于所述弹性胶管在自然状态下的内径，所述插接管挤压插接在所述弹性胶管内，使得所述插接管第二端的外周壁和弹性胶管的内周壁之间形成紧密的配合，形成密封。本发明通过采用弹性胶管与插接管过盈插接配合的方案，利用弹性胶管自身的弹性，形成密封，无需额外增设其他密封结构，简化了残水引导管路整体的结构，成本更低。
更优选地，所述弹性胶管为与所述窗垫2一体成型设置的橡胶管，所述插接管与外筒1一体成型设置。所述橡胶管与窗垫2、所述插接管与外筒1分别通过注塑一体成型设置，无需通过连接结构连接，成型更简单。
本发明通过采用第一引导管31为与窗垫2一体成型设置的橡胶管，第二引导管32为与外筒1一体成型设置的插接管的方案，使得第一引导管31和第二引导管32成型更简单，加工更方便，且减少了洗衣机冗杂的零配件，简化了装配。
优选地，本发明实施例中所述第二引导管32的第二端具有一导向部，所述第二引导管32的第二端端口呈缩径设置形成所述导向部，所述导向部具有一呈圆台状的导向周壁，圆台状的的导向部小口径端朝向所述第一引导管31。通过在第二引导管32的第二端端部设置的导向部起到导向的作用，使得所述第二引导管32能够更轻松地插接到第二引导管32内，提高装配效率。
如图1、图2、图6所示，本发明实施例中，所述窗垫本体的周壁外靠近外筒1侧设置有一圈用于加强所述第一引导管31结构的连接加强筋25，所述连接加强筋25为环形片状的加强筋，与第一引导管31的周壁靠近第二端侧连接固定，增强第一引导管31的结构强度及稳定性，避免第一引导管31的端部耷落等现象发生，使得所述第一引导管31在与第二引导管32插接过程中稳定性更高。
进一步地，所述窗垫2还包括罩设在褶皱部21外的环形保护罩24，通过设置的 环形保护罩24避免洗衣机箱体内的部件刮伤、挤压窗垫2等。所述保护罩24对应所述残水引导管路或者排残水口211的位置设有避让开口241。通过设置的避让开口241便于安装师傅安装装配所述第一引导管31在与第二引导管32，并且使用的过程中若出现意外状况，如第一引导管31或第二引导管32堵塞，维修师傅也可以从机体的外部通过该避让开口241直接操作疏通第一引导管31或第二引导管32，装配、维修更加便利。
如图4和图5所示，本发明实施例中，所述外筒1为横向设置的前端开口的筒体结构，所述窗垫本体为横置的筒状结构，所述排残水口211开设在褶皱部21的最底部位置。由于所述排残水口211开设在褶皱部21的最底部位置，只要褶皱部21内有一点水就会排出，不会有任何残留，排残水更彻底，更能保证洗衣机内部洁净卫生的环境。
需要说明的是，本发明所述外筒1不限于横向设置，当然也可以采用竖直筒，同样可以应用本发明实施例中残水引导结构的方案，将窗垫内的残水引导至竖直设置的外筒内。
本发明实施例中，所述入水口101高度低于所述排残水口211设置，所述第一引导管31和第二引导管32为自所述排残水口211向入水口101方向逐渐向下倾斜设置的倾斜管路。通过将所述入水口101低于所述排残水口211设置，环形腔210内的残水则可顺着倾斜的第一引导管31和第二引导管32流淌至外筒1内，第一引导管31和第二引导管32内也不会出现残留洗涤水的问题。
如图4和图5所示，在一种实施方式中，所述残水引导管路内设置有异物阻挡结构，所述异物阻挡结构阻挡环形腔210内的线屑杂质进入到外筒1内部。本发明通过在残水引导管路内设置有异物阻挡结构，能够有效地阻挡窗垫2内的线屑杂质进入外筒1内部，同时也能阻挡外筒1内的线屑杂质进入到窗垫2内，有效地避免线屑杂质通过残水引导管路在窗垫2和外筒1之间流动，影响整个洗衣机的清洁效果。
如图4和图5所示，所述异物阻挡结构为设置在第二引导管32内的挡筋321或者过滤件，所述挡筋321或者过滤件设置在第二引导管32内靠近第二端的位置。所述过滤件可以为设置在第二引导管32内一个小的滤芯或者过滤网结构。
优选地，所述异物阻挡结构为间隔设置在第二引导管32内的多个挡筋321，采 用挡筋321的方式阻挡线屑杂质加工成型更简单，易于实现，成本更低。
所述挡筋321的面积小于第二引导管32的横截面积，相邻两个挡筋321在周向方向上错位分布设置，通过将多个挡筋321在周向方向上错位分布设置，既不影响正常引导残水，且又能够增强线屑过滤阻挡的效果。
进一步地，所述窗垫2包括与外筒1筒口处的外筒法兰12相嵌套配合的内唇，所述外筒1的前边缘向筒口中心方向延伸后向靠近窗垫2的方向延伸并向外翻折形成所述外筒法兰12，所述外筒法兰12内形成开口朝向外周侧的环形状的第一卡接槽。
如图4和图5所示，所述内唇包括上下相间隔设置的第一卡接部22和第二卡接部23，所述第一卡接部22和第二卡接部23之间形成第二卡接槽，所述外筒法兰12卡接限位在第二卡接槽内，所述第二卡接部23卡接限位在第一卡接槽内。
在上述方案中，通过在窗垫2内唇上下相间隔设置的第一卡接部22和第二卡接部23，外筒法兰12卡接在第一卡接部22和第二卡接部23形成的第二卡接槽内，第一卡接部22卡接在外筒法兰12形成的开口向下的第一卡接槽内，采用相互嵌套配合的卡接结构实现装配连接，使得窗垫2与外筒1之间连接更加牢固，不易脱落，且形成双重密封，密封效果更好。
进一步地，所述外筒1包括筒状的筒周壁以及筒周壁前端开口边沿向内弯折延伸形成的环形端壁11，所述入水口101开设在环形端壁11上，所述外筒法兰12连接在环形端壁11的内周边沿和窗垫2的内唇之间。
所述第一卡接部22由褶皱部21的内周边沿向外筒1的方向延伸形成，所述第二卡接部23包括连接在褶皱部21周壁外的水平连接壁、以及水平连接壁向筒口中心方向延伸后反向弯折形成的弧形弯折壁。所述弧形弯折壁挤压限位在外筒法兰12的第一卡接槽内，所述外筒法兰12伸入卡接在第二卡接槽内。
本实施例中，所述弧形弯折壁的端壁与残水引导管路之间具有第一间隙距离，所述水平连接壁与残水引导管路之间具有第二间隙距离，所述第二卡接部23与第一引导管31路之间形成容错空间，利用第一卡接部22和第二卡接部23的弹性及收缩性能，实现窗垫2与外筒1之间的装配连接。
本发明中所述洗衣机还包括可转动地设置在外筒1内的无孔内筒(图中未示出)，所述无孔内筒在洗涤衣物时独立盛放洗涤水。
本实施例中的洗衣机优选地为无孔内筒洗衣机，所述内筒的筒体上设有排水孔，所述排水孔上安装有密封件，当所述无孔内筒在洗涤状态时，所述密封件处于关闭状态，可以密封无孔内筒，当所述无孔内筒在脱水状态时，所述密封件处于打开状态，使得无孔内筒的洗涤用水排到外筒1。
所述密封件可以为安装在排水孔内的离心阀，所述离心阀在内筒低速转动时封闭所述排水孔，在高速脱水状态下在离心力的作用下打开所述排水孔进行排水。
本发明实施例中所述的残水引导结构3应用在无孔内筒的洗衣机上更具明显的优势，无孔内筒的洗衣机在洗涤衣物时，内筒上的排水孔处于封闭状态，由于内外筒1之间无水，一方面不会出现洗涤过程中外筒1内的洗涤水通过该残水引导结构3进入到窗垫2内的现象，另一方面也不会出现残水引导结构3排出的残水也进入到内筒内的现象，影响衣物的清洁效果。
洗衣机在洗涤脱水程序结束后，进入排水状态时，设定外筒1的最高排水水位为H1，本发明中所述入水口101高于最高排水水位H1，避免外筒1内的洗涤水通过残水引导管路反向逆流到窗垫2内。
应该注意的是上述实施例对本发明进行说明而不是对本发明进行限制，并且本领域技术人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。在列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
