Description

一种洗衣机的控制方法及免清洗洗衣机 技术领域
本发明属于洗衣机技术领域，具体涉及一种洗衣机的控制方法及免清洗洗衣机。
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、或者直接设置封闭内筒，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，还避免了洗涤水流在内外筒之间流动还需对内外筒之间进行清洗的问题；同时，由于还可以在洗衣机上不设外筒、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。
如何提供一种适于不设置主排水结构的洗衣机，以进行洗涤或漂洗排水的洗衣机控制方法，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。

下面结合本发明的部分具体实现方式进行详细的解释和说明，以便于更好地理解本发明。
实施例1
如图3-6所示，本发明提供一种洗衣机的控制方法。
所述洗衣机参照图1和图2，包括无孔内筒1，无孔内筒1设有排水口4，排水口4处设置密封阀；
当洗衣机执行排水或脱水时，控制无孔内筒1以对应的设定转速进行旋转，以使所述密封阀借助内筒旋转的离心力打开排水口4，将无孔内筒1内的水排出。
本发明所述的洗衣机为滚筒洗衣机，在本实施例中所述的洗衣机为滚筒洗衣机，通过控制无孔内筒1的转速进行控制。
当洗衣机执行脱水时，控制无孔内筒1以第一设定转速进行旋转；当洗衣机执行排水时，控制无孔内筒1以第二设定转速进行旋转。
上述的第一设定转速是根据时间对应不同的具体转速值的转速曲线，第二设定转速可以是某一设定的具体转速值或根据时间对应不同的具体转速值的转速曲线。
在洗衣机的无孔内筒以第一设定转速转动时，密封阀的阀芯受离心力作用以打开排水口4，且使筒内水流贴壁流动；在洗衣机的无孔内筒以第二设定转速转动时，密封阀的阀芯所受离心力与闭合力相抵消以打开排水口4。
和洗衣机脱水相比，洗衣机执行排水时，无孔内筒1受到的离心力比较小，无孔内筒1内的水流可以绕过衣物自然垂落，以汇聚到排水口4中。
所述的第二设定转速的取值范围为50-300转/分，优选为90-200转/分。
作为优选地，洗衣机执行脱水时的第一设定转速大于执行排水时的第二设定转速。
作为一种实施方式，在洗衣机即将执行排水或脱水前，执行至少一次均布过程，通过叠加不同水流对无孔内筒1内的衣物或/和水进行均布。从而便于无孔内筒1内的水贴着内壁汇集到所述排水口4处，快速顺畅地排出无孔内筒1。
作为一种实施方式，通过调整无孔内筒1的转停比t形成不同水流实现的衣物或/和水的均布。
在洗衣机即将执行排水前，控制无孔内筒1以设定的对应转停比t1运行一定时间，所述的转停比t满足以下条件：T1＜t1＜T2。
在洗衣机即将执行脱水前，控制无孔内筒1以设定的对应转停比t2运行一定时间，所述的转停比t2满足以下条件：T3＜t2＜T4。
排水口4处设有水质检测装置，无孔内筒1的外部设有水存储装置，排水口4设有可控制分别与水存储装置或洗衣机的出水管相连通的排水路径；
当洗衣机执行漂洗程序的排水时，所述的水质检测装置实时检测水清洁度，判断是否符合回收条件；
若是，则控制排水口4与水存储装置相连通，以使自所述排水口4排出的水进入水存储装置；
若否，则控制排水口4与洗衣机的出水管相连通，以使自排水口4排出的水直接排至洗衣机的外部。
作为一种实施方式，上述的水质检测装置为电导率检测装置，洗衣机中预设有电导率数据库，当洗衣机即将执行排水时，电导率检测装置开始检测水流的电导率，并与预设的电导率数据库进行比较判断，当电导率的测定值落入预设的电导率数据库时，判断流水的水质符合回收条件，控制排水口4与水存储装置相连通，以使自所述排水口4排出的水进入水存储装置。
作为一种实施方式，洗衣机执行洗涤或漂洗时，判断所述水存储装置内的水位是否高于或等于设定水位；
若是，则控制水存储装置的水进入无孔内筒1内以洗涤或漂洗衣物；
若否，则控制洗衣机从外部水源进水至无孔内筒1。
本发明的另一目的在于提供一种免清洗洗衣机，包括无孔内筒1，无孔内筒1设有排水口4，排水口4处设置密封阀；采用根据上述内容所述的洗衣机的控制方法来控制脱水或排水。
作为一种实施方式，排水口4处设有水质检测装置，无孔内筒1的外部设有水存储装置，排水口4设有可控制分别与水存储装置或洗衣机的出水管相连通的排水路径。
本发明的洗衣机不需要设置用于洗涤排水或漂洗排水的主排水结构，通过可借助无孔内筒1进行旋转而产生的离心力控制密封阀打开排水口4，简化洗衣机的结构，降低成本。
实施例2
本实施例涉及一种本发明所述的洗衣机的一种具体结构。
洗衣机包括壳体100，壳体100内设有无孔内筒1，无孔内筒1轴线水平延伸或自前向后逐渐向下倾斜设置，无孔内筒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。
无孔内筒1筒壁上不设通孔，以使得无孔内筒1内部构成仅前部开口设置的密封容器。同时，洗衣机壳体100前端安装有可向外打开的门盖400，以在门盖400闭合后封闭内筒筒口101、打开门盖400后自内筒筒口101向无孔内筒1中投放衣物的目的。
无孔内筒1后端经内筒支撑件300安装于洗衣机壳体100内，所述的内筒支撑件300与无孔内筒1后端同轴设置，内筒支撑件300的上下两端分别向无孔内筒1前端筒口方向弯折，弯折部至少延伸至无孔内筒1中部，上下弯折部分别经减震吊簧610和减震支撑杆620与洗 衣机壳体100相连接，以实现内筒支撑件300可震动得安装于洗衣机壳体100内的目的。
同时，内筒底中心与洗衣机驱动电机500的电机轴同轴设置，以驱动无孔内筒1旋转，无孔内筒1和驱动电机500均固定安装于内筒支撑件300上。优选的，内筒底与驱动电机500分别设置与内筒支撑件300的两侧，驱动电机500于内筒支撑件300相固定连接，驱动电机500的电机轴经轴承穿过内筒支撑件300并与内筒底同轴固定连接，且驱动电机500轴可相对内筒支撑件300旋转，以实现无孔内筒1和驱动电机500安装于内筒支撑件300上、并令无孔内筒1可独自在驱动电机500作用下进行旋转对内部衣物进行洗涤的目的。
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或排水程序的目的。
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，只需将洗衣机无孔内筒1设置为没有脱水孔、门盖400闭合内筒筒口101后形成密封容器的洗衣机。本发明实施例中的洗衣机还可以适用于顶开式洗衣机，在内筒侧壁上设置衣物投放口，并在内筒侧壁上设置可向外翻转开闭的、对应密封衣物投放口的门体，以在内筒停止旋转后定位至对应位置，令用户可对应打开门体，自衣物投放口向洗衣机内筒内部投放、或取出衣物。同时，通过将内筒设置为门盖扣合后进行洗涤的密封容器，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。
如图1所示，为了将洗衣机内筒筒口101进行密封扣合、防止洗涤水自内筒筒口外流，并实现洗衣机工作过程中无孔内筒1密封盛水进行正常洗涤，洗衣机内筒筒口101处设有可开合封闭开口的内筒盖700，以在内筒盖700对应扣合内筒筒口101后内筒形成密闭的容器。所述的内筒盖700独立设置，内筒盖700的外周与内筒筒口101密封贴合，以对内筒筒口101进行密封处理。通过将内筒盖相对独立设置，令用户仅需单独对内筒盖开闭操作，就可实现对内筒筒口密封扣合的目的。
如图1和图2所示，洗衣机壳体100内设有无孔内筒1，无孔内筒1后部为内筒底，内筒底的中心处经向后轴向延伸的转轴与内筒支撑件300相连接；内筒底的中心处于进水管900的一端相连通，进水管900穿过转轴并向上延伸与洗衣机进水盒相连通，进水管900上设有控制水路流动开闭的进水阀和/或进水泵，以实现洗衣机自内筒后部向内进水的目的。
同时，可以在进水管900上设置加热装置，以自进水管900流入内筒中的水流进行加热，实现对内筒中洗涤水水位进行调控，进而达到洗衣机内筒中采用合适温度洗涤水进行洗涤的目的。
通过上述设置，使得洗衣机自内筒底中心处进水，并使得内筒筒口经内筒盖闭合密封，使得自内筒中心处进水、并对内筒中盛水进行密封，使得内筒可在进水后进行正常旋转、并使进水管不会随内筒旋转而产生位移，进而实现了内筒旋转过程中内筒密封、排水时排水阀打开内筒中盛水正常外排的效果,达到了内筒旋转和盛水双重功效的洗衣机正常进水的目的；同时，使得内筒外部可不需再套装外筒，增大了内筒的容积，提高了洗衣机的洗涤容量。
本实施例中，为了提高进水平稳性，可以进行如下设置：内筒底设有引导水流分散流向无孔内筒1内部的喷淋进水结构910，以使得经进水管900流入无孔内筒1内部的洗涤水经喷淋进水结构910作用而形成发散状的喷淋水，喷淋水喷射至无孔内筒1内部，以提高进水水流的覆盖面积和均匀程度、进而提升衣物的浸湿效率。
无孔内筒1的侧壁安装有至少一个提升筋2，提升筋本体为下侧为敞口、扣合于无孔内筒1内侧壁的壳体结构，升筋本体内部中空以构成供密封阀安装的安装腔3，所述密封阀安装结构设于安装腔3内。
所述密封阀安装结构包括安装于无孔内筒1内侧壁上的支撑板9，支撑板9中部设有与无孔内筒1侧壁上所设排水口4相对应的通孔，支撑板9与无孔内筒1侧壁之间相距一定间隙，以构成供密封阀阀芯上下移动的空间。支撑板9上侧固定安装有套筒状的安装套6，安装套6的内侧通孔与支撑板9上所设通孔同轴相对设置，以将密封阀的阀芯同轴、可上下移动的安装于内侧通孔中。
所述密封阀阀芯结构还包括对应安装于无孔内筒1侧壁所设排水口的阀塞柱5，与阀塞柱5上端相铰接的配重块7，无孔内筒1侧壁上固定安装有密封阀安装结构，密封阀安装结构与阀塞柱5之间夹持有复位弹簧。
在内筒上安装上述阀塞结构，可利用配重块在离心力作用下而产生对应打开排水口的动作，还可利用复位弹簧将阀塞柱拉复位、令阀芯对应封堵排水口，进而实现了利用内筒高速旋转的离心力对阀塞柱作用、而对应开闭排水口的目的。
无孔内筒1的外部对应设有集水槽320，集水槽320的底部与洗衣机排水管310相连通，以对自无孔内筒1外排水流收集后外排。排水管处设有排水阀330，以对应控制排水管的通 断开闭。
集水槽320包括位于无孔内筒1的下方对应设置的凹槽，凹槽的后侧壁向上竖直延伸至无孔内筒1的上方、并与无孔内筒1相距一定间距、同轴设置，节省洗衣机内部的空间。同时，集水槽320的前侧壁与无孔内筒1下部之间相贴合、或间隙为极限小的距离，以保证集水槽320中水不会自前端溅射出、进而避免了内筒排水溢流情况的发生。
本实施例中，所述集水槽320安装于洗衣机的内筒支撑件300上、或与内筒支撑件300一体成型，阀芯开启机构安装于集水槽320上。
实施例3
本实施例是对实施例2中的洗衣机的结构的进一步优化或限定。
无孔内筒1底排布有多条自外周延伸至中心的导水流道，无孔内筒底中心设有与各导水流道端部分别相连通的中心接头，中心接头的后端设有穿出无孔内筒底的出水接口；无孔内筒的外部设有水存储装置，水存储装置的出水口可控制开闭地与无孔内筒内部连通；所述的出水接口设有支路，分别连通水存储装置的进水口或洗衣机的出水管；无孔内筒中的洗涤水受离心力作用、经导水流道流向中心接头后再经出水接口流入水存储装置，或者排至洗衣机外部。
所述的水存储装置为与无孔内筒同轴设置的筒状结构，水存储装置的出口处设有控制阀，通过所述控制阀使出口与无孔内筒连通或洗衣机的出水管连通。
本实施例的洗衣机可以对内筒排出的水进行有区别的处理，回收再利用或者直接排出洗衣机的外部，可以节省水资源，更加环保。
作为优选地，为了精简洗衣机的构造，降低成本，提高洗衣机结构的利用率，上述的水水存储装置可以是针对上述实施例3的集水槽320进行改造后得到的结构，也可以是另外单独设置的。
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。
