Description

一种进水结构及洗衣机 技术领域
本发明属于洗衣机技术领域，具体涉及一种进水结构，还涉及一种装有上述进水结构的洗衣机，尤其涉及一种设洗涤过程中可旋转、可盛水内筒的洗衣机。
背景技术
现有技术中，滚筒洗衣机一般包括相互套装的内筒和外筒，外筒密封用于盛水，内筒用于盛放衣物、经旋转内筒以对衣物进行摔打洗涤；同时，内筒上设置脱水孔，以使得外筒中的水经脱水孔流入内筒以对内筒中的衣物进行浸泡、内筒中的水经脱水孔流出至外筒、内筒中衣物上水分在内筒高速旋转时经脱水孔外排至外筒，以实现对衣物进行洗涤的目的。
但是，由于内筒与外筒相互套装，在洗衣机使用过程中内外筒之间容易积存污垢；同时，由于内外筒相互套装，用户无法对内筒外壁、外筒内壁进行清洁，使洗衣机内部细菌增多，降低了洗衣机的洗衣效率、衣物洗涤后的洁净度。
同时，上述现有洗衣机中，由于内筒外部套装有外筒，洗衣机的洗涤过程是通过内筒旋转对衣物进行摔打洗涤，使得洗衣机的洗涤容量是以内筒为基准，令洗衣机的内部空间使用率较低，无法在现有基础上对洗衣机洗涤容量进行扩展。
有鉴于此，如何设置一种洗衣机，以将内外筒合一，令内筒设置为密封容器，既能盛水和衣物，又能旋转对衣物进行摔打进行洗涤；同时，由于洗衣机不设外筒、或外筒与洗衣机壳体一体设置，还能使洗衣机的内筒扩大、以扩展洗衣机的洗涤容量，就成为了研发热点。
但是，由于内筒不仅用于盛放洗涤水，还要旋转以对筒内衣物进行摔打清洗，因此如何设置一种适用于上述洗衣机的进水结构，就成为了急需解决的难题。
鉴于上述技术缺陷，特提出本申请。
发明内容
本发明的目的在于提供一种进水结构，以实现向旋转部件供水的目的；本发明的另一目的在于提供一种洗衣机进水结构，以达到将洗涤水直接引流入洗衣机内筒的目的。
为了解决所述的技术问题，达到所述的技术效果，本发明采用的技术方案的基本设计思路为：
一种洗衣机进水结构，其包括内部中空形成进水流道的传动轴，传动轴的进水端对应插入动密封座围成的腔室内，传动轴与动密封座的对应插接处安装有一圈动密封圈。
进一步，动密封圈包括一圈外周壁与动密封座的插接口内壁相贴合接触的密封唇，密封唇的内周壁设有径向凸出延伸的支撑筋，支撑筋的延伸端与传动轴插入端的外壁相动密封接触。
进一步，动密封圈的密封唇的内周间隔排布有多条支撑筋，各支撑筋的延伸端均与传动轴的插入端外壁相密封接触；
进一步，各支撑筋的延伸端经连接筋相连接。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至图7所示，本发明实施例中介绍了一种洗衣机，洗衣机包括壳体2，壳体2内设有内筒1，内筒1轴线水平延伸或自前向后逐渐向下倾斜设置，内筒1前端为开口设置的内筒筒口101、后端为密封设置的内筒底102，内筒侧壁103将内筒筒口101与内筒底102相连以构成内筒1；内筒1筒壁上不设通孔，以使得内筒1内部构成仅前部开口设置的密封容器。同时，洗衣机壳体2前端安装有可向外打开的门盖4，以在门盖4闭合后封闭内筒筒口101、打开门盖4后自内筒筒口101向内筒1中投放衣物的目的。内筒1后端经内筒支撑件3安装于洗衣机壳体2内，所述的内筒支撑件3与内筒1后端同轴设置，内筒支撑件3的上下 两端分别向内筒1前端筒口方向弯折，弯折部至少延伸至内筒1中部，上下弯折部分别经减震吊簧和减震支撑杆与洗衣机壳体2相连接，以实现内筒支撑件3可震动得安装于洗衣机壳体2内的目的；同时，内筒底102中心与洗衣机驱动电机5的电机轴同轴设置，以驱动内筒1旋转，内筒1和驱动电机5均固定安装于内筒支撑件3上。优选的，内筒底102与驱动电机5分别设置与内筒支撑件3的两侧，驱动电机5于内筒支撑件3相固定连接，驱动电机5的电机轴经轴承穿过内筒支撑件3并与内筒底102同轴固定连接，且驱动电机5的电机轴可相对内筒支撑件3旋转，以实现内筒1和驱动电机5安装于内筒支撑件3上、并令内筒1可独自在驱动电机5作用下进行旋转对内部衣物进行洗涤的目的。优选的，驱动电机5的电机轴直接构成内筒轴21，内筒轴21与内筒1的内筒底102同轴固定连接。
还有，本发明实施例中的洗衣机可以为现有技术中任一具备门盖闭合内筒筒口后内筒构成密封容器的洗衣机，以在洗衣机执行脱水程序时，控制内筒高速旋转，以将内筒中自衣物脱离的水流顺利外排出内筒，进而达到对无孔内筒洗衣机正常执行脱水程序的目的。因此，本发明实施例中的洗衣机并不局限于附图中的结构，例如：还可以，采用现有普通洗衣机，只需将洗衣机内筒1设置为没有脱水孔、门盖4闭合内筒筒口101后形成密封容器的洗衣机。
同时，通过将内筒设置为门盖扣合后、洗衣机进行洗涤时形成密封容器，使得洗涤过程中衣物只与密封内筒中的洗涤水接触，避免了内外筒之间洗涤水流入内筒中污染衣物情况的发生，大大提高了洗衣机的洗涤洁净度，避免了内外筒之间被洗涤水污染造成洗衣机清洗衣物不彻底情况的发生。
本发明实施例中为了向洗衣机内筒1中进水，进行如下设置：
如图1至图6所示，一种洗衣机进水结构，其包括内部中空形成进水流道25的传动轴21；传动轴21的进水端对应插入动密封座23围成的腔室27内，传动轴21与动密封座23的对应插接处安装有一圈动密封圈25，动密封座23上装有对传动轴21的插入端进行限位支撑的轴承26。通过上述设置，使得旋转的传动轴与固定的动密封座之间形成连通通道，以实现将洗衣机进水水流引入旋转部件中的效果；同时，在插接处设置动密封圈，以达到对传动轴插接处进行有效密封、防止漏水的效果。
本发明实施例中，洗衣机安装有上述的进水结构，传动轴21同轴安装于内筒底101，传动轴21的出水端与内筒1固定连接、且传动轴21内部中空流道25的出水端与内筒1内部相连通，动密封座23围成的腔室27与洗衣机进水管22相连通，以使洗衣机进水水流沿进水管流入动密封座所围腔室中、再由传动轴中空形成的进水流道流入内筒中，在此过程中由于传 动轴与动密封座之间以插接连接，使得旋转的传动轴的中空进水流道与不动的动密封座围成的腔室之间相连通，进而形成转动部件与固定部件相连通的流道，以实现将洗衣机进水水流导入旋转内筒中的目的。
本发明实施例中，内筒1在洗衣机洗涤过程中形成密封盛水容器，内筒1外部安装有经挂簧和/或减震件与洗衣机壳体相连接的内筒支撑件3，传动轴21穿过内筒支撑件3，将内筒1可旋转的安装于内筒支撑件3上；动密封座23固定安装于内筒支撑件3上。本发明实施例中的内筒支撑件可以为将内筒套装与内部的外筒，也可以为其他形式的、仅具有支撑安装功能的结构件，例如：在内筒底后侧设置的、竖直延伸的支撑架。
本发明实施例中，动密封圈25包括一圈外周壁与动密封座23的插接口内壁相贴合接触的密封唇28，密封唇28的内周壁设有径向凸出延伸的支撑筋29，支撑筋29的延伸端与传动轴21插入端的外壁相密封接触。本发明实施例中，动密封圈25为由自身可产生弹性变形的橡胶等材质构成，以利用动密封圈25的自身弹性变形而对相接处进行密封处理。本发明实施例中，动密封圈25的密封唇28由可自身可产生弹性变形的材质构成，例如：橡胶等。优选的，为了保证密封效果，密封唇28的外周径尺寸大于动密封座23插接口的内周尺寸，从而，利用密封唇自身弹性，而使其受挤压后产生变形、进而插接固定于动密封座上。
如图3所示，本发明实施例中，动密封圈25的密封唇28的内周间隔排布有多条支撑筋29，各支撑筋29的延伸端均与传动轴21的插入端外壁相密封接触。至少一道支撑筋29处于动密封圈25朝向动密封座23所围腔室27的一端。本发明实施例中，动密封圈25的支撑筋29依然由可自身可产生弹性变形的材质构成，例如：橡胶等。通过在密封唇上设置多道支撑筋，以使动密封圈与传动轴之间形成多道密封结构，以提升动密封座的密封性、降低腔室内的水流产生外泄的几率。
优选的，各支撑筋29的延伸端经连接筋相连接，以使得各支撑筋29的延伸端相互构成连接以形成与传动轴21外壁相密封贴合接触的筒状套筒，使动密封圈25与传动轴21之间形成面接触、进而提升密封性能(未在附图中注明)。
如图4所示，本发明实施例中，密封唇28内部镶嵌有刚性材质构成的骨架33，所述骨架33为沿动密封圈25周向方向连续、或间隔延伸的弧形结构。通过在密封唇内部镶嵌设置骨架，以提升密封唇的自身刚性，进而使密封唇在受力挤压后不会产生结构性变形，令动密封圈的自身强度得以保证、提升动密封圈的密封性能。
本发明实施例中，动密封座23包括相连通的第一腔室31和第二腔室32，第一腔室31 为与传动轴21同轴设置的筒状腔室，第二腔室32为一端封闭、另一端与第一腔室31相连通，第一腔室31的径向宽度大于第二腔室32，第一腔室31和第二腔室32的对应端同竖直面设置、并经连接壁30相连接；传动轴21自筒状第一腔室31远离第二腔室32的一端插入、并抵触于第一腔室31和第二腔室32相连的连接壁。
优选的，如图6所示，动密封圈25靠近第二腔室32的一端面设有至少一圈径向凸出的密封筋34，密封筋34的凸出端与连接壁30相密封接触，以提升动密封圈的密封性能。
本发明实施例中，传动轴21插入端的开口至少部分与第一腔室31和第二腔室32的连通处相重叠设置，使得自动密封座23所围腔室27流经的进水水流可直接流入传动轴21的中空进水流道24中，令进水水流更为顺畅。
本发明实施例中，沿传动轴21插入动密封座23的方向依次设置轴承26和动密封圈25，轴承26处于动密封座25围成腔室27的外侧，以避免轴承与腔室内水流接触、提升轴承的使用寿命。
本发明实施例中，轴承26装于动密封圈25内，轴承26为外周排布有齿形、内周呈平滑弧面的环形滑动轴承；传动轴21插入端对应穿过轴承26、并与动密封座23的内壁相限位接触，轴承26的外周与动密封圈25的密封唇28内周壁相限位连接；优选的，密封唇28内周壁设有与轴承外周所设齿形相对应啮合的内周齿。优选的，轴承26与动密封圈25上所设支撑筋29相交错排布，使轴承26被直接包裹于动密封圈25内，简化了装配。
本发明实施例中，传动轴21的插入端沿插入方向依次设置有啮合部213、固定部212和滑动部211，啮合部213的外周壁排布有径向凸出的啮合齿、固定部212的外周壁设有外螺纹、滑动部211的外周壁为光滑圆弧面，传动轴21的至少部分滑动部211对应穿过动密封圈25、插入动密封座23所围腔室27内。洗衣机电机的转子同轴插接于传动轴21上，转子与传动轴21啮合部213的啮合齿相对应啮合、形成绕轴共同旋转的连接。转子直接与传动轴21固定部212的外螺纹相啮合、或传动轴21外套装有螺母，螺母与传动轴21固定部212的外螺纹相啮合，以在传动轴21径向方向上将转子与传动轴21相固定。
本发明实施例中，洗衣机的内筒1上设有洗涤常闭孔6，所述的洗涤常闭孔包括：孔，设于内筒上，贯通设置，以供水流穿过；离心阀，安装于内筒上、对应设于孔处，离心阀的阀芯对孔进行封堵，并在内筒转速达到设定值后离心阀的阀芯受离心力作用而打开。优选的，离心阀还包括一弹性件，弹性件夹持于阀芯与内筒之间，以对阀芯提供复位作用力、而推动阀芯封堵孔。上述的离心阀可以为现有技术中任一可实现受离心力作用而打开孔的阀体结构。
如图7所示，本实施例中，洗涤常闭孔6可以进行如下设置，内筒侧壁103上设有孔，内筒侧壁103内侧安装有离心阀9。离心阀9包括安装于内筒1内侧的支架，支架上安装有相铰接的配重块，孔处设有可上下移动的阀塞柱，阀塞柱与配重块相铰接，阀塞柱与内筒侧壁103之间加持有复位弹簧，以在内筒1旋转离心力作用下带动配重块向远离内筒1轴线方向移动，进而通过铰接处拉动阀塞柱向内筒1轴线方向移动而打开孔。
优选的，内筒侧壁103内侧安装有向内筒中心凸出的提升筋8，提升筋8内部中空，提升筋8上设有将内筒1与内部中空相连通的透水孔。洗涤常闭孔6的孔设置于提升筋8相对应的内筒侧壁103上，并将提升筋8内部中空与内筒1外相连通。离心阀设于提升筋8的内部中空部。
当然，本发明实施例中的洗衣机还可以为现有的普通洗衣机，同样可以直接应用上述进水结构，以相洗衣机构成盛水容器的外筒中进水、而对内筒中盛放衣物进行直接喷射接触的效果。
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。
