Description

洗涤设备

技术领域
本发明涉及家电设备技术领域，具体提供一种洗涤设备。
背景技术
洗衣机的洗涤筒通常设置成双层筒，即包括固定于洗衣机外壳内的外筒以及设置于外筒内的能够过水的内筒，外筒的筒体封闭，能够盛装洗涤水，内筒上设置有过水孔，能够盛装衣物。上述筒结构的设置使得外筒每次洗衣时均需长时间容纳洗涤水，导致洗涤水中携带的脏污杂质极易残留于外筒内壁上，但外筒内壁又因内筒的遮挡而很难被可靠清理，使得洗衣机长期使用后其外筒与内筒之间经常会残留大量污垢并滋生细菌，降低洗衣机的内部卫生环境。
为了上述问题，目前部分洗衣机的内筒被设置成无孔形状，并且内筒上设置有排水结构，以便通过上述内筒直接盛装洗涤水，无需外筒辅助盛装。在此情形下，排水结构位置通常设置有电磁阀，以便在洗衣机排水时控制电磁阀通电打开以连通内筒和外部实现排水。上述洗衣机的弊端在于：电磁阀需驱动电机提供动力，驱动电机故障时将不能满足洗衣机的排水需求，因此为了保证驱动电机的工作稳定性以及维修便利性，驱动电机需被进行高可靠性地防水设置，并且还需在洗涤筒内占用较大布置空间，整体布置要求较高。

下面结合洗涤设备为滚筒洗衣机的情形来描述本发明的技术方案：
如图1-2所示，本发明的滚筒洗衣机包括机壳1以及设置机壳1内的筒组件、进水组件5、排水阀组6和排水管7。其中，机壳1为箱体结构，箱体结构的前侧设置有衣物投放口以及能够打开/封闭衣物投放口的机门11。筒组件包括固定于箱体内的外筒2以及以同轴转动方式设置于外筒2内的无孔内筒3，外筒2以筒口朝前并对准衣物投放口的方式横置安装于机壳1内，外筒2的筒口位置安装有能够封闭无孔内筒3的内筒门21，在内筒门21关闭的情形下，无孔内筒3的筒口被可靠封堵。用于驱动无孔内筒3转动的驱动电机4设置于外筒2的筒底中心的外侧，驱动电机4的驱动端连接有传动轴41，传动轴41伸入外筒2并连接至无孔内筒3的筒底转动中心位置，以便将驱动电机4的转矩传输至无孔内筒3进而驱动无孔内筒3转动。无孔内筒3上设置有用于进水的进水口和用于排水的排水口31，进水组件5能够将外部水源引入端和进水口连通，以便将进水引入无孔内筒3。示例性地，进水组件5包括进水管52以及设置于进水管52上的进水阀51，传动轴41的内部轴心部位设置有进水结构411，进水结构411能够沿传动轴41的轴线在轴内形成一条导水通路，进水结构411的出水端连通至进水口，进水结构411的进水端连通至进水管52的出水端，进水管52的进水端连通至外部水源引入端，以便滚筒洗衣机能够通过进水管52和进水结构411向无孔内筒3中进水。排水管7的进水端与外筒2内部连通，排水管7的出水端连通于外部，排水口31能够将无孔内筒3的内部与外筒2内部连通，以便允许无孔内筒3中的洗涤 水通过排水管7排出至外部。
为了使无孔内筒3仅在排水情形(如洗涤排水、漂洗排水或筒清洁排水等情形)下打开排水口31、在非排水情形下(如预洗、洗涤或漂洗等情形)关闭排水口31，上述排水阀组6设置于无孔内筒3上的排水口31位置，该排水阀组6具体包括连接组件62、弹性构件63和阀芯61。其中，阀芯61的形状与排水口31的形状相匹配，以便阀芯61能够通过停留于排水口31的孔口端或者通过至少一部分进入排水口31内的方式封堵排水口31，并且阀芯61分别通过连接组件62和弹性构件63连接至无孔内筒3。弹性构件63设置成能够在非排水情形下促使阀芯61保持封堵排水口31的状态，以及能够通过弹性变形方式允许阀芯61在无孔内筒3排水转动时借助离心力作用克服其弹力作用而远离排水口31移动并因此打开排水口31。连接组件62设置成能够引导阀芯61在排水情形下远离排水口31移动，以及能够引导阀芯61在非排水情形下借助弹性构件63的回弹作用复位移动，以便在非排水情形下重新移回至能够封堵排水口31的位置。其中，无孔内筒3排水转动具体是指无孔内筒3以高于洗涤转速的设定转速转动，在无孔内筒3以该设定转速转动的情形下，能够产生促使阀芯61克服弹性构件63的弹力而远离排水口31移动的离心力。本领域技术人员可以根据无孔内筒3的驱动环境以及排水转动需求调整设定转速的具体转速值，只要无孔内筒3以设定的设定转速转动时所产生的离心力能够促使阀芯61远离排水口31移动以打开排水口31并保持打开排水口31的状态即可。
基于上述结构，当滚筒洗衣机进水后，在非排水情形下，无孔内筒3根据工况需求以低于上述设定转速的转速转动，如在洗涤情形下以低于设定转速的洗涤转速正反往复转动，在此过程中，弹性构件63能够支撑阀芯61保持封堵于排水口31的状态，以便阻止洗涤水从无孔内筒3中流出。
在排水过程中(如衣物洗涤/漂洗后、进入脱水过程时)，无孔内筒3以设定转速持续转动，以便产生的离心力能够促使阀芯61克服弹力远离排水口31移动，从而打开排水口31，使得无孔内筒3通过排水口31与外筒2连通，进而使无孔内筒3中的洗涤水通过排水管7排出，弹性构 件63被移动的阀芯61带动而被拉伸或被压缩变形。
在排水结束后，无孔内筒3停转或以低于设定转速的转速转动，离心力变小或消失，弹性构件63恢复弹性变形的动作促使阀芯61被带动靠近排水口31移动进而重新封堵排水口31。
在阀芯61远离或靠近排水口31移动时，连接组件62能够限制阀芯61以设定路径移动，以便促使阀芯61在受到离心力或弹力作用移动时能够与排水口31保持基本对准的状态，防止阀芯61在打开或封堵排水口31移动时未对准排水口31导致封堵失效或者因与其余部件摩擦干涉而移动不顺畅。
在上述实施方式中，阀芯61远离排水口31移动具体是指阀芯61顺应离心力促进方向通过排水口31朝向无孔内筒3外部(即靠近外筒2内侧壁的方向)移动。在能够满足阀芯61的移动促进、复位以及移动导向的需求的情形下，连接组件62和弹性构件63在无孔内筒3上的设置位置不是限定的，弹性构件63和连接组件62既可以任意一个设置于无孔内筒3的内部，另一个设置于无孔内筒3与外筒2之间，也可以均设置于无孔内筒3的内部，或者均设置于无孔内筒3与外筒2之间，本领域技术人员可以结合无孔内筒3和外筒2的侧壁间隔设置需求、筒组件的布置需求以及阀芯61的移动复位需求等设定连接组件62和弹性构件63的具体布置位置。
在一种可能的实施方式中，上述连接组件62包括连杆组件，阀芯61通过连杆组件连接至无孔内筒3，连杆组件能够通过伸展/收拢变形方式引导阀芯61远离排水口31移动，并且能够通过收拢/伸展变形方式引导阀芯61靠近排水口31复位移动。
继续参阅图2，作为示例，上述连杆组件和弹性构件63均设置于无孔内筒3的内部。其中，连杆组件包括对称设置的两个杆组，按照图2方位所示，在排水口31如图中的竖向方位设置的情形下，两个杆组相对于阀芯61左右对称设置，每个杆组均包括枢转连接的第一连杆621和第二连杆622，第一连杆621远离其同组第二连杆622的一端与无孔内筒3的内侧枢转连接，同组第二连杆622远离其连接的第一连杆621的一端与阀芯61枢转连接，在连接好的情形下，每组第一连杆621和第二连杆 622在阀芯61封堵于排水口31位置时均存在夹角、处于未伸展状态。上述弹性构件63为设置于无孔内筒3内的弹簧，该弹簧优选设置于阀芯61的侧端中部、两个杆组之间，并且弹簧的两端分别连接至无孔内筒3的内侧和阀芯61，以便弹簧的弹力能够均匀不偏置地传递至阀芯61，防止阀芯61被弹簧驱使相对于排水口31偏移移动。
在非排水情形下，阀芯61封堵于排水口31内，弹簧处于自然状态并支撑阀芯61保持其封堵位置(即图2示出的布置方式)；或者，阀芯61以卡置于排水口31的出水侧的方式封堵于排水口31位置，弹簧被拉伸变形进而通过收缩回弹趋势促使阀芯61保持其卡置封堵位置。上述各杆组的第一连杆621和第二连杆622之间在此情形下均存在夹角、处于未伸展状态；
在排水情形下，无孔内筒3排水转动并产生促使阀芯61远离排水口31向外移动的离心力，在离心力作用下，阀芯61克服弹簧的弹力向外移动，弹簧以被拉伸变形的方式允许阀芯61远离排水口31移动，每个杆组的第一连杆621和第二连杆622均伸展变形、每组第一连杆621和所述第二连杆622之间的夹角变大，以便引导阀芯61远离排水口31朝外移动；
在排水结束的情形下，无孔内筒3结束排水转动动作，离心力变小或消失，弹簧回弹并促使阀芯61靠近排水口31复位移动，每个杆组的第一连杆621和第二连杆622之间的夹角变小，以便通过收拢变形方式引导阀芯61对准排水口31移动并复位至能够重新封堵排水口31的位置。
如图2所示，进一步地，无孔内筒3的内侧壁设置有朝向筒内隆起的提升筋32，提升筋32包括与无孔内筒3的内侧壁相连的外壳321以及设置于外壳321的壳壁上的过水孔3211，过水孔3211能够将外壳321内的空腔与外部连通，以便允许无孔内筒3的洗涤水通过过水孔3211进入外壳321内。上述排水口31设置于无孔内筒3的侧壁上并且被外壳321罩设，上述杆组、弹簧和阀芯61均设置于外壳321内，以便通过外壳321将连杆组件和弹簧与无孔内筒3内部的洗涤空间分隔。上述提升筋32还包括安装支架322，该安装支架322设置于外壳321内，并且安装支架322与外壳321和/或无孔内筒3相连，上述第一连杆621和弹簧分别通 过安装支架322连接至无孔内筒3的内侧壁，以便将提升筋32和排水阀组6集成设置，便于维修人员根据检修需求拆卸外壳321或提升筋32整体以检修排水阀组6。
更进一步地，无孔内筒3上设置有导向结构3221，导向结构3221对准排水口31设置，以便引导阀芯61对准排水口31移动。具体而言，上述导向结构3221为设置于安装支架322上的导槽，该导槽的形状与阀芯61相适配，并且导槽的槽口与排水口31彼此对准，以便辅助连杆组件引导阀芯61以对准排水口31的方式移动。
优选地，上述阀芯61包括阀芯基体611以及设置于阀芯基体611上的密封结构612，在阀芯61封堵排水口31的情形下，密封结构612位于排水口31内或封堵于排水口31的进水侧/排水侧，以便关闭排水口31，从而提升封堵可靠性。
关于上述，需要说明的是，本发明的排水阀组6的弹性构件63和连接组件62的设置方式并不局限于上述优选示例，连接组件62和弹性构件63的具体结构以及布置方式均不是限定的。例如，上述连接组件62还可以为滑轨和滑块的滑动导向连接结构，上述弹性构件63还可以是弹片等其他具有弹性变形以及弹性支撑需求的构件。即便是设置成连杆组件和弹簧，其布置方式也均不是限定的，例如，弹簧在设置于无孔内筒3的外侧壁时，弹簧还可以通过压缩变形方式将阀芯61抵压至排水口31的出水侧进而封堵排水口31，连杆组件还可为其余能够满足导向需求的连杆结构，只要弹性构件63和连杆组件的设置能够满足阀芯61的驱动和导向需求即可。
继续参阅图2，针对上述任一种实施方式，上述排水阀组6优选还包括配重构件64，上述配重构件64设置于连杆组件上，以便通过提升连杆组件部分整体质量的部分提升其惯性，从而在无孔内筒3排水转动时借助离心力作用辅助连杆组件变形运动并因此促进阀芯61远离排水口31移动，强化连杆组件对阀芯61的导向推动效果，优化阀芯61打开排水口31时的移动顺畅性。
可替代地，上述配重构件64还可以设置于阀芯61上，以便直接提升阀芯61惯性，从而在无孔内筒3排水转动时借助离心力作用进一步促 进阀芯61远离排水口31移动，优化阀芯61打开排水口31时的移动顺畅性。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
