Description

一种衣物处理设备的控制方法及衣物处理设备 技术领域
本发明涉及家用电器中的衣物处理设备，具体的说，涉及一种具有无孔滚筒的衣物处理设备，特别涉及一种不具有脱水孔的无孔滚筒的排水控制方法。
背景技术
随着人们生活水平的进步，现在的洗衣机普遍都集成了一些其他的衣物处理功能，例如：具有衣物烘干功能的洗干一体机、干衣机等，具有除皱、熨烫功能的复新机等等，这些衣物处理设备逐渐走入了大众的家庭。
现有的具有衣物洗涤功能的衣物处理设备大体上可分为波轮式、搅拌式及滚筒式。但无论上述哪种形式的衣物处理设备在对衣物进行洗涤处理时，都是通过水和洗涤剂的作用去除洗涤物的污渍，以实现衣物进行洗涤的效果。
在滚筒式衣物处理设备中，一般具有壳体，内部安装有用于容纳洗涤水的外筒，在外筒的内侧设置有用于容纳洗涤物的滚筒，在外筒的背面设置有用于旋转上述滚筒的电机和轴。
上述现有的滚筒式衣物处理设备，在执行洗涤程序时，洗涤水会在滚筒和外筒之间交叉流动，会导致滚筒外部、外筒内部之间普遍留存有大量污垢，为了避免上述污垢对洗涤水的污染，申请人之前就提出了一种将内外筒合二为一的无孔滚筒衣物处理设备，以克服滚筒和外筒之间留存污垢的问题。上述无孔滚筒衣物处理设备在执行排水时，是利用滚筒旋转离心力驱动排水口处的阀体打开，令滚筒内的洗涤水自排水口流出，流出的排水水流流至集水容器中进行收集，再经与集水容器相连的排水管外排出衣物处理设备。
但是，上述的无孔滚筒衣物处理设备的滚筒排水口处设置的阀体普遍是在滚筒转速达到设定值后，打开、或闭合排水口，这就存在如下问题：
在衣物处理设备排水过程中、尤其是排水程序初期，衣物处理设备容易因排水过急而导致集水槽内水位过高等情况的发生，甚至会导致排水水流外溢至衣物处理设备外部的问题。
有鉴于此，特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种衣物处理设备的控制方法及衣物处理设备，以实现对排水流速进行可控调节的目的；还有，本发明还提供了一种衣物处理设备的控制方法及衣物处理设备，以对排水程序进行智能调控，进而达到避免排水溢流的目的。
为解决上述技术问题，本发明采用的技术方案的基本构思是：
一种衣物处理设备的控制方法，衣物处理设备的滚筒上设有至少一个排水口，排水口处设有离心排水阀；在滚筒转速超过设定值后，离心排水阀受离心力驱动而打开排水口，在执行排水程序时，滚筒以大于等于设定值的转速、和小于设定值的转速交替运行。
进一步，在排水过程中，交替执行步骤s1和步骤s2；
步骤s1、在设定时间t1内，滚筒以大于等于设定值的转速进行旋转；
步骤s2、在设定时间t2内，滚筒以小于设定值的转速进行旋转。
进一步，在排水过程中，每次执行步骤s1和s2时，所需的t1和t2为变量；
在排水过程中，每次执行步骤s1所需的时长t1依次递增、每次执行步骤 s2所需的时长t2依次递减；
优选的，t1的递增量和t2的递减量均为同一设定值。
进一步，在执行步骤s2时，滚筒以低于设定值的转速、以设定转停比进行正反向旋转，搅动滚筒内负载进行均布、和/或对滚筒内洗涤水进行消泡。
进一步，在排水初期，滚筒以大于等于设定值的转速、小于设定值的转速交替旋转运行；
在排水后期，滚筒以大于设定值的转速持续旋转运行。
进一步，在排水过程中，控制滚筒以大于最大设定值、低于最小设定值的转速进行旋转，控制部分排水口打开、部分排水口闭合；
优选的，在排水初期，控制滚筒以小于最大设定值、大于等于最小设定值的转速n1，和低于最小设定值的转速n0交替旋转运行；
在排水中期，控制滚筒以大于等于最小设定值的转速n2持续运行；
在排水后期，控制滚筒以大于等于最大设定值的转速n3持续运行。
进一步，滚筒自排水口流出的排水水流流入外筒；在排水过程中，对外筒内的水位进行液位监测；当液位检测值高于设定值后，控制滚筒转速下降至设定值以下；当位检测值低于设定值后，控制滚筒转速上升至设定值、或以上。
进一步，在滚筒转速下降至设定值以下的持续时长超过设定值t时，判定排水堵塞，停止滚筒旋转，发出排水堵塞的报警提示。
进一步，在外筒内的水位达到最大水位时，判定排水堵塞，停止滚筒旋转，发出排水堵塞的报警提示。
本发明还提供了一种衣物处理设备，其采用上述任一所述的衣物处理设备的控制方法。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果：
通过上述设置，对衣物处理设备的滚筒以可调转速的形式控制排水口的开闭状态，以对滚筒排水口开闭时间比进行相应调节的目的，达到控制衣物处理设备的无孔滚筒的排水流速的效果，进而避免了衣物处理设备的滚筒排水水流过急、产生排水外溢等情况的发生。
同时，本发明结构简单，方法简洁，效果显著，示意推广使用。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

如图1至图4所示，本发明实施例中介绍了一种衣物处理设备，其包括滚筒3，滚筒3为不具有常开通孔的桶状结构，在衣物处理设备执行洗涤衣物程序时滚筒可独立盛放洗涤水、并可进行旋转，利用旋转作用力摔打衣物和水而实现对滚筒内衣物进行洗涤处理的效果，避免了衣物处理设备工作过程中洗涤水在滚筒3内外交叉流动，造成洗涤水被筒外堆积的污垢和细菌污染而无法对衣物进行彻底清洗的问题。
本发明实施例中，滚筒3上设有至少一个排水口4，各排水口4处分别安装有离心排水阀5，各离心排水阀5的阀芯6对应封堵排水口4，使得衣物处理设备在正常工作过程中，滚筒的排水口在阀芯作用下被封堵，进而保证滚筒形成 密封盛水容器。同时，在滚筒3转速达到设定值后，阀芯6受离心力驱动而对应打开排水口4，使得滚筒3内盛放的洗涤水自排水口4向外排出，流至滚筒3外部的集水容器中，然后经集水容器底部相连通的排水管10流出衣物处理设备。
本发明实施例中，所述的集水容器为一独立部件，可以为其他设置于滚筒下方、外周的集水槽，也可以由现有的外筒2(如图1至图4所示)直接构成等等。
本发明实施例中，滚筒3可旋转的安装于支撑件上，所述的支撑件可以为独立件、也可以为其他件；优选的，如图1至图4所示，本发明实施例中，所述的支撑件为套设于滚筒外部的外筒2，外筒2经减震支撑件，可伸缩移动的安装于衣物处理设备的壳体1内，所述的外筒2构成将滚筒自打开的排水口4流出的排水水流进行收集的集水容器。
如图5至图7所示，本发明实施例中，所述的衣物处理设备的控制方法，衣物处理设备的滚筒上设有至少一个排水口，排水口处设有离心排水阀；在滚筒转速超过设定值后，离心排水阀受离心力驱动而打开排水口，在执行排水程序时，滚筒以大于等于设定值的转速、和小于设定值的转速交替运行。
通过上述设置，对衣物处理设备的滚筒以可调转速的形式控制排水口的开闭状态，以对滚筒排水口开闭时间比进行相应调节的目的，达到控制衣物处理设备的无孔滚筒的排水流速的效果，进而避免了衣物处理设备的滚筒排水水流过急、产生排水外溢等情况的发生。

在排水后期，滚筒以大于设定值的转速持续旋转运行。
实施例三
本实施例中介绍了一种衣物处理设备的控制方法，衣物处理设备的滚筒上设有至少一个排水口，排水口处设有离心排水阀；在滚筒转速超过设定值后，离心排水阀受离心力驱动而打开排水口，在执行排水程序时，滚筒以大于等于设定值的转速进行旋转，并在排水过急时减慢滚筒转速，使滚筒的至少部分排 水口关闭，以实现减缓排水流速、防止衣物处理设备排水溢出的目的。
如图1至图4所示，本实施例中，衣物处理设备包括：滚筒3，滚筒3上设有多个排水口4，各排水口4处分别设有离心排水阀5；在滚筒3转速超过设定值后，离心排水阀5受离心力驱动而打开对应排水口4；至少一个离心排水阀5打开排水口4所对应的滚筒3转速设定值不同于其他离心排水阀5。
本实施例中，在排水过程中，控制滚筒以大于最大设定值、低于最小设定值的转速进行旋转，控制部分排水口打开、部分排水口闭合。
本实施例中，滚筒上设有两类以上的排水口，每类排水口的离心排水阀打开所对应的滚筒转速设定值不同，最小的转速设定值为最小设定值、最大的转速设定值为最大设定值。
如图7所示，本实施例中，衣物处理设备的排水过程的具体步骤如下：
在排水初期，控制滚筒以小于最大设定值、大于等于最小设定值的转速n1，和低于最小设定值的转速n0交替旋转运行；
在排水中期，控制滚筒以大于等于最小设定值、小于等于最大设定值的转速n2持续运行；
在排水后期，控制滚筒以大于等于最大设定值的转速n3持续运行。
如图1至图4所示，本实施例中，离心排水阀5包括，
阀芯6，对应封闭排水口4；

离心驱动结构，随滚筒3共同旋转，受滚筒3转动离心力作用而克服闭合复位结构施加给阀芯6的闭合作用力，产生拉动阀芯6的位移、打开排水口4。
上述的闭合复位结构可以为弹簧、液压杆、气压杆等现有任一或组合所述的弹性组件，例如：如图2和图3所示，闭合复位结构由处于压缩状态的弹簧9， 弹簧9的两端分别与阀芯6和滚筒3相连，压缩的弹簧9对阀芯6施加沿滚筒3径向向外移动、闭合排水口4的推动力；至少一个离心排水阀5的弹簧6的弹性系数不同于其他离心排水阀5。

本实施例中，为了达到不同离心排水阀5打开排水口4所对应的滚筒3转速设定值不同可以进行如下设置：
如图1和图2所示，本实施例中，滚筒3上设有至少一个离心排水阀5的阀芯6所受闭合复位结构施加的闭合作用力不同于其他离心排水阀5，以使得不同离心排水阀5的闭合复位结构进行不同设置，以达到对离心排水阀5的阀芯6闭合对应的滚筒3转速设定值进行相应调整的目的；
和/或，如图4所示，本实施例中，滚筒3上设有至少一个离心排水阀5与滚筒3筒轴之间的距离不同于其他离心排水阀5，以使得不同距离的离心排水阀5的阀芯6在滚筒3同一转速时所受离心力不同，进而实现不同位置处的离心排水阀5在不同滚筒3转速时打开、使得不同位置处的离心排水阀5的阀芯6所对应打开的滚筒3转速设定值不同；
和/或，如图1和图3所示，本实施例中，滚筒3上设有至少一个离心排水阀5的离心驱动结构的质量不同于其他离心排水阀5，以使得不同离心排水阀5的离心驱动结构在滚筒3同一转速时所施加给阀芯6的打开作用力不同设置， 进而达到不同排水口4处的离心排水阀5打开所对应的滚筒3转速设定值不同的效果。
