Description

一种洗衣机 技术领域
本发明属于洗衣机领域，具体地说，涉及一种洗衣机的滚筒的轴向限位结构；尤其涉及一种应用于洗衣机的可拆卸滚筒的、利用滚筒旋转离心力而实现锁止动作的轴向限位结构。
背景技术
洗衣机具有滚筒，滚筒可绕轴旋转的固定安装于洗衣机内，用于盛放衣物等待处理负载。
现有洗衣机的滚筒一般都是利用螺钉、螺栓等固定安装于洗衣机的外筒中的。这样设置的滚筒洗衣机，虽然滚筒的安装较为牢靠，不易脱离；但是，用户无法直接取放滚筒，使得还需单设独立的取衣篓，令用户的操作较为繁琐。
同时，滚筒固定安装于洗衣机中还存在如下问题：
用户无法较为便利的拆装滚筒，就使得滚筒无法更换；尤其是，在用户对卫生条件要求较高时，一个洗衣机的对应的多个用户无法实现使用专属滚筒，利用专属滚筒对衣物进行洗涤的使用要求。
从而，就会出现一个洗衣机对应的多个用户的衣物会产生相互接触，导致细菌的相互传播。
有鉴于此，特提出本发明。

本发明中，外筒400包括，刚性材质构成的外筒支架401和柔性材质构成的弹性套筒402，外筒支架401呈凹槽状，凹槽状外筒支架401至多覆盖滚筒200的一半高度；凹槽状外筒支架401的槽底构成外筒底、槽底的外侧安装电机500，凹槽状外筒支架401的槽口连接同轴设置的弹性套筒402的第一端，弹性套筒402的第二端与衣物投放口外围的洗衣机的壳体100的前侧板的内侧壁相密封相连；优选的，弹性套筒402与外筒支架401同轴设置。本发明实施例中，外筒的弹性套筒402的第二端设有径向凸出的一圈弹性密封唇403，弹性密封唇403与机门700相密封接触，使得衣物投放口的外周形成一圈密封，令外筒400内形成密封盛水空间。外筒支架401的最低处与洗衣机的排水管18相连通，用于将洗衣机流入外筒400中的排水向外排出。
同时，本发明中，外筒400设置为，轴线自后向前逐渐向上倾斜的设置，保证外筒400内的水绝大部分处于外筒的外筒支架401处，以减少弹性套筒402受力，进而提升外筒400使用强度和寿命；洗衣机的外筒400的轴线与水平面之间具有一定夹角a，10°≤a≤60°；优选的，25°≤a≤45°。
本发明中，外筒400的外筒支架401经弹性支撑件600与洗衣机壳体100相连，使得外筒400在弹性支撑件600的作用下可缓冲减震的安装于洗衣机壳体100内；优选的，外筒支架401的下侧与竖直延伸的弹性支撑件600的上端相连，弹性支撑件600的下端与壳体100的底部相连，所述弹性支撑件600可以为现有的任一由弹簧、液压杆、气压杆等可产生轴向弹性变形的部件构成；进一步优选的，外筒支架401的左右两侧分别经至少一个弹性支撑件600与外壳100底部相连，左右两侧弹性支撑件600相对外筒400轴线对称排布。
本发明中，洗衣机的滚筒支架300设置为凹槽状，凹槽状滚筒支架300同轴设置于外筒 支架401内，滚筒支架300外周的支架槽壁302与外筒支架401的侧壁之间保持一定间距，滚筒支架300的支架槽底301与外筒支架401的槽底之间保持间距、且滚筒支架300的支架槽底301的中心与传动轴17伸入外筒400内的端部固定相连；优选的，滚筒支架300的轴向高度低于外筒支架401，使得滚筒支架300全部处于外筒支架401内部。进一步优选的，滚筒200的外侧壁与凹槽状滚筒支架300的内侧壁同轴等径设置，以减小二者之间的相对晃动。
本发明中，凹槽状滚筒支架300的内壁设有凹凸部303，所述凹凸部303的至少部分与滚筒200轴线相交错排布；滚筒200上设有配合凹凸部205，滚筒200放置于滚筒支架300上，凹凸部303对应插入对应的配合凹凸部205中，实现滚筒200和滚筒支架300之间的插接相连、并在周向上相对锁止，令滚筒200和滚筒支架300可在凹凸结构的作用下共同绕轴旋转。
优选的，如图1至图12所示，在滚筒支架300的支架槽底301的中心处设有向内凸出的凹凸部303，凹凸部303上设有径向凸出部分、凸出部分与滚筒200的轴线相偏心排布，进而实现至少部分凹凸部303与滚筒300轴线偏心排布，保证滚筒200与滚筒支架300之间的周向限位，令二者可以共同绕轴旋转；进一步优选的，凹凸部303设置为相对滚筒200轴线非对称的结构，令凹凸部303构成定位部件，以使得滚筒200仅能以特定方位插接放置于滚筒支架300上，以保证离心锁止件与锁止槽可插接的相对同轴开设。
由于本发明中的洗衣机的滚筒200仅通过滚筒筒底201与滚筒支架300之间的凹凸结构来实现滚筒200与滚筒支架300之间的共同旋转连接，使得滚筒200在轴向不受外力限制，就会使得滚筒200在轴向产生位移、甚至滚筒脱离滚筒支架300情况的发生。而现有的洗衣机，在执行滚筒转速较低的洗涤等程序时，由于滚筒200内所盛放的衣物和水的自重，就可实现滚筒200轴线限位、避免轴向位移情况的发生；但是在执行滚筒200转速较高的脱水等程序时，由于滚筒200转速较大会产生较强的离心力，就会使得滚筒200被离心力作用而甩出、与滚筒支架300相脱离等情况的发生。
本发明实施例中，为了避免上述问题的发生，对滚筒200加装了轴向限位结构，以对滚筒200施加轴向锁止，令滚筒200在轴向不会产生移动、进而避免滚筒200脱离滚筒支架300情况的发生。
同时，为了便于用户对滚筒200的拆装，轴向限位结构利用滚筒200旋转离心力做为驱动力，令滚筒200转速较低或静止时，轴向限位结构不作用于滚筒200，以方便用户取放滚筒200；而在滚筒200转速较高时，轴向限位结构受离心力作用而作用于滚筒200，令滚筒200在轴向进行锁止，避免滚筒200位移、甚至脱离情况的发生。
还有，为了防止不同滚筒200内的洗涤水相互流动，本发明中的滚筒200采用不设常开过水通孔的无孔滚筒200形式，具体如下：
如图1至图12所示，滚筒200一端设有滚筒筒口203、另一端封闭设置构成滚筒筒底201，两端经筒状的滚筒筒壁202相连；滚筒200上除滚筒筒口203外不设常开通孔，用于将滚筒200构成可盛水的容器；优选的，滚筒筒壁202上设有将两侧贯穿的排水口8，滚筒200上设置的排水口8处具有离心阀2，以使得滚筒200以低速旋转、洗衣机执行洗涤等程序时，离心阀2对应闭合排水口8，滚筒200形成盛水容器；而在滚筒200以高速旋转、洗衣机执行脱水等程序时，离心阀2对应打开排水口8，滚筒200内的水受离心力驱动而自排水口8外排至外筒400中。从而，使得滚筒200与外筒400之间不会形成交叉水流，杜绝了不同滚筒200内的水均与外筒400相接触、导致不同滚筒200之间间接的形成交叉水流情况的发生，进一步提升了洗衣机的清洗效果。
实施例一
如图1所示，本实施例中介绍了一种洗衣机，其包括：滚筒200，用于盛放衣物；滚筒支架300，可绕轴旋转的设于洗衣机内，供滚筒200放置；离心锁件1，安装于滚筒200上，用于滚筒1转速超过设定值后，受离心力作用而径向伸出至与滚筒支架300相插接。
通过上述设置，使得洗衣机滚筒转速较高时将离心锁件自动伸出，以实现洗衣机执行较高转速的脱水等程序时滚筒与滚筒支架间在轴向上相对锁止的功能；同时，利用滚筒转速产生的离心力对离心锁件进行对应操控，不仅节约了成本、还提升了控制精度。
本实施例中，离心锁件1，沿滚筒200径向延伸，可向外伸出的安装于滚筒筒壁202上；离心锁件1与滚筒筒壁202之间夹持有弹性件，用于向离心锁件1施加保持于未向外伸出位置的止动弹力。
本实施例中，离心锁件1自身由较重的金属材质构成、或者其上单独设置有金属材质构成的配重部，用于提升离心锁件1自身质量、增大其所受的离心力，进而保证离心锁件1受离心力驱动的精准性。
如图1所示，本实施例中，离心锁件1呈沿滚筒径向延伸的杆状主体，杆状主体朝向滚筒200内部的一端设有径向凸出的限位部5；杆状主体外周套设有弹簧4，弹簧4两端分别与限位部5和滚筒200内壁相接，用于保持弹簧4对离心锁件1施加止动弹力、令离心锁件1保持在不向外伸出的状态。
本实施例中，滚筒筒壁202上设有穿孔6，穿孔6贯穿滚筒筒壁202，杆状离心锁件1的一端对应插入穿孔6内，另一端设有限位部5；弹簧4套设于杆状离心锁件1的外周，弹簧4两端分别与限位部5和滚筒200内壁相抵接，使得弹簧4被夹持于离心锁件1与滚筒200之间，弹簧4对离心锁件1施加弹力，用于保持离心锁件1处于不向外伸出的状态。
本实施例中，滚筒支架300上设有锁止槽3，用于与受离心力推动而伸出的离心锁件1相插接；优选的，锁止槽3与离心锁件1设于滚筒200的同一径向截面中、同一径向方位中。本实施例中，滚筒支架300与滚筒200之间经凹凸结构可形成周向方位固定的相对插接，滚筒支架300上的设定位置处设有供离心锁件1相插接的、与离心锁件1径向同尺寸设置的插接槽3。优选的，所述的锁止槽3为自开口向内逐渐收窄径向尺寸的锥形敞口槽，以便于离心锁件1对应插入锁止槽3内。
当然，上述的锁止槽3还可以设置为贯穿滚筒支架300的锁止孔，同样可以实现供离心锁件1插入，令滚筒200与滚筒支架300之间形成锁止插接的效果(未在附图中注明)。
如图1所示，本实施例中，离心锁件1设置于滚筒筒壁202上、靠近滚筒筒底201处，以尽量靠近相对传动轴17处，进而提升离心锁件1的定位锁止效果；锁止槽3对应设置于滚筒支架300的支架槽壁302的内周侧，用于供同轴设置的离心锁件1对应插入。
本实施例中，为了保证滚筒的密封性，可以在离心锁件1与穿孔6的相接处设置密封圈7，使得离心锁件1穿过滚筒处实现密封隔水的效果。
如图1所示，在洗衣机处于非工作、洗涤等低转速状态时，离心锁件1受弹簧4作用力而保持与非伸出状态，离心锁件1的端部插入穿孔6中、并不向外凸出，离心锁件1与锁止槽3相分离，在轴向上滚筒200与滚筒支架300之间不设限位，用户可以将滚筒200自由取出。
在洗衣机处于脱水等高转速状态时，离心锁件1受高速旋转的滚筒200产生的离心力驱动而克服弹簧4弹力向外伸出，离心锁件1的端部穿过穿孔6、向外凸出插入锁止槽3内，离心锁件1和锁止槽3相插接，在轴向上滚筒200与滚筒支架300受伸出的离心锁件1的限位，无法再产生位移，有效避免了滚筒200相对滚筒支架300移动、甚至脱离情况的发生。
实施例二
如图2至图5所示，本实施例中介绍了一种洗衣机，其包括，滚筒200，用于盛放衣物；滚筒筒壁202上设有径向向滚筒内部凸出的提升筋204；提升筋204内部中空，中空部安装有离心锁件1；离心锁件1，对应插接于滚筒筒壁202上所设的穿孔6处，并受弹性件作用而保持于收缩位置，用于在滚筒200转速达到设定值n1后受离心力作用而克服弹力、伸至滚筒200外部并与滚筒支架300上所设锁止槽3内。
本实施例中，提升筋204由一侧敞口、内部围成腔室的壳体结构构成；提升筋204的敞 口侧对应扣合于滚筒筒壁202的内侧，提升筋204扣合处的滚筒筒壁202上设有穿孔6，穿孔6贯穿滚筒筒壁202，将滚筒200外部和提升筋204内部腔室相连通。
优选的，为了提升提升筋204处的强度，可以在提升筋204与滚筒筒壁202之间加装安装板，提升筋204的敞口侧对应扣合于安装板上，安装板安装于滚筒筒壁202上(未在附图中注明)。

本实施例中，滚筒筒壁202上安装有安装套9，安装套9具有与穿孔6同轴开设的通道，柱状离心锁件1同轴对应插入安装套9的通道内。
如图2至图5所示，本实施例中，安装套9包括构成通道的、沿滚筒200径向延伸的套筒部91，套筒部91的一端设有径向向外凸出的、呈环状的径向凸出部92，径向凸出部92与穿孔6外围的滚筒筒壁202对应贴合接触；径向凸出部92与滚筒筒壁202之间夹持有至少一道密封圈7；优选的，密封圈7分为位于径向凸出部92与滚筒筒壁202之间的、呈环形的第一密封部71，和位于柱状离心锁件1与安装套9的通道内壁之间的、呈筒状的第二密封部72。
为了实现离心锁件1穿出处的密封，还可以进行如下设置：柱状离心锁件1的外周径向尺寸等大或稍大于安装套9上设置通道的内周径向尺寸，用于柱状离心锁件1与安装套9的相接处构成密封接触(未在附图中注明)。
如图2至图5所示，本实施例中，柱状离心锁件1的一端对应插入套筒部91所围的中心通道中，另一端凸设于安装套9外部、提升筋204的中空腔室内；柱状离心锁件1的凸设端设有径向凸出的限位部5，离心锁件1的限位部5与安装套9的径向凸出部92之间夹持有弹簧4，弹簧4同轴套设于柱状离心锁件1和套筒部91的外周。
本实施例中，安装套9的径向凸出部92的外周设有向上弯折的、呈筒状的一圈挡边部93，挡边部93与套筒部91的外壁之间形成有一圈环形凹槽，弹簧4的端部位于环形凹槽内，以实现对弹簧4端部进行插接固定的效果。
本实施例中，提升筋204内还设有离心阀2，用于在滚筒200转速达到设定值n2后受离心力作用而打开滚筒筒壁202上设置的排水口8；滚筒200的转速设定值n1小于等于n2，以保证洗衣机在执行滚筒200以较高转速旋转的脱水等程序时，先将滚筒200与滚筒支架300在轴向相锁止后再打开排水口8处的离心阀2，进而保证脱水等过程中滚筒200不会与滚筒支架300之间产生轴向位移或脱离。同时，为了保证排水口8流出排水水流的顺畅外排，在滚筒支架300上设有贯通设置的通孔19，通孔19与排水口8同轴相对设置、通孔19的孔径大于等于排水口8孔径，以实现滚筒200排水水流可依次经排水口、通孔19流至外筒400中。
如图2至图5所示，本实施例中，离心阀2可以采用如下结构：离心阀2包括，阀芯柱11，下端对应封闭滚筒200上的排水口8；阀芯座10，安装于滚筒筒壁202上，阀芯柱11可轴向伸缩移动的安装于阀芯座10上，阀芯座10与阀芯柱11之间夹持有弹簧15，用于对阀芯柱11施加闭合排水口8的弹力；杠杆12，中部可绕支点旋转的安装于阀芯座10上，杠杆12的一端与阀芯柱11上端可旋转的相连、另一端与配重块13相连；杠杆12和配重块13均沿滚筒200轴线平行方向延伸，杠杆12与阀芯座10可相对旋转的转轴的轴线沿滚筒筒壁202的切线方向延伸。
本实施例中，提升筋204上设有多个过水孔14，过水孔14将提升筋204内部腔室和外部的滚筒200内部空间相连通，用于引导滚筒200内的水流入提升筋204内部，进而达到利用提升筋204内部所设排水口8对滚筒200内蓄水进行外排的效果。

如图5所示，滚筒200再以设定值n2转动，离心锁件1受高速旋转的滚筒200产生的离心力保持于伸出状态，依然对应插入锁止槽3内；同时，离心阀2的配重块13受离心力作用而克服离心阀2上的弹簧15弹力产生向外位移，利用杠杆结构使离心阀2的阀芯柱11被撬动而打开排水口8，滚筒200内的蓄水经打开的排水口8向外流出。

通过上述设置，使得离心锁件随离心阀同步动作，实现了洗衣机排水和滚筒轴向锁止同步开启的效果，进而保证了洗衣机的滚筒高速旋转执行排水程序时滚筒被轴向锁止定位，有效避免了洗衣机脱排水过程中滚筒脱离情况的发生。
本实施例中，配重块13绕撬杠结构的支点旋转，配重块13远离撬杠结构支点的一端设有朝向滚筒筒壁202凸出设置的离心锁件1。
优选的，本实施例中，离心锁件1为沿圆弧线延伸的柱形，圆弧线的圆心为撬杠结构的支点，以使得离心锁件1可以配合撬杠结构运行，而自穿孔6处对应伸出或收回；滚筒筒壁202上所设的穿孔6为轴线沿同一圆弧线延伸的通孔，用于配合离心锁件1伸出、缩回移动(未在附图中注明)。
如图6至图8所示，本实施例中，穿孔6外围的滚筒筒壁202上安装有密封圈7，用于对离心锁件1穿过穿孔6处进行密封处理；密封圈7的第一端自由设置、供离心锁件1对应穿过，第二端固定安装于穿孔6外围的滚筒筒壁202上。

本实施例中，离心锁件1与配重块13、杠杆12设置为一体件，以提升结构强度、减少部件数量。
如图7所示，在洗衣机处于非工作、洗涤等低转速状态时，离心阀2的阀芯柱11受弹簧15作用力而保持于封闭滚筒200上所设的排水口8的位置；配重块13受阀芯柱11牵引而处于远离滚筒筒壁202位置；配重块13上设置的离心锁件1的端部插入穿孔6中、并不向外凸出，离心锁件1与锁止槽3相分离，在轴向上滚筒200与滚筒支架300之间不设限位，用户可以将滚筒自由取出；同时，离心阀2的阀芯柱11对应封闭滚筒200上所设的排水口8，滚筒200形成盛水容器，滚筒200旋转过程中利用内部承载的水对衣物等负载进行处理。
如图8所示，在洗衣机处于脱水等高转速状态时，滚筒200以大于或等于设定值的转速转动，离心阀2的配重块13受离心力作用而克服离心阀2上的弹簧15弹力产生向滚筒200径向向外的位移，利用杠杆结构使离心阀2的阀芯柱11被撬动上升而打开排水口8，滚筒200内的蓄水经打开的排水口8向外流出；同时，离心锁件1随配重块13同步向外伸出，离心锁件1的端部穿过穿孔6、向外凸出插入锁止槽3内，离心锁件1和锁止槽3相插接，在轴向上滚筒200与滚筒支架300之间受伸出的离心锁件1的限位，而无法再产生相对位移，有效避免了滚筒200相对滚筒支架300移动、甚至脱离情况的发生。
