一种滚筒洗衣机的控制方法及滚筒洗衣机 技术领域
本发明涉及洗衣设备技术领域,具体地,涉及一种滚筒洗衣机的控制方法及滚筒洗衣机。
背景技术
洗衣机作为人们日常生活中使用最为广泛的一种家用电器,帮助人们摆脱了洗衣的烦恼,给人们带来了极大的便利。但是洗衣机也具有一定的缺点,比如说耗时较长、耗水量较大等,随着社会的发展,水资源作为一种重要的自然资源变得越来越重要,人们的节水意识也随之提高,而如何实现洗衣机的节水功能便显得尤为重要。
为了解决洗衣机的节水问题,现在也提出了一些专利,比如专利号为201410215346.3,名称为一种滚筒洗衣机的中国发明专利,该发明涉及一种滚筒洗衣机,包括箱体,箱体内设有内筒和外筒,外筒与箱体之间设有门封,内筒与驱动装置相连,所述的内筒为无孔内筒,且所述的内筒为筒底处直径小、筒口处直径大的锥形筒,内筒的筒口处向内呈弧形收拢,所述的门封上设有进水导管,进水导管的一端与洗涤水快速加热装置相连,进水导管的另一端穿过门封伸入内筒内,所述的外筒上设有排水口及水压检测装置。由上述技术方案可知,该发明的内筒为无孔内筒,通过设置在门封上的进水导管实现内筒进水,并通过内筒自身的形状在脱水过程中实现排水,这样可以避免在内、外筒之间存水,大幅节约了洗涤用水量。
上述发明提供了一种具有无孔内筒的滚筒洗衣机,但仅仅是将现有滚筒洗衣机的内筒设计为无孔结构,现实意义很小。因为衣物洗涤须有一定的洗涤水浸泡,如果要实现浸泡的效果,无孔内筒中的需要存有一定的水量,这样会增大电机的负担,耗电等问题也随之而来。另外,该专利公开的滚筒洗衣机进水的方式是通过门封,由于门封主要的作用是实现洗衣机外筒的筒口的密封,在门封上设置进水导管容易影响门封的密封效果,不易实现,且该专利不能实现对内筒内进水水位的检测。
另外,针对于采用无孔内筒的滚筒洗衣机,如何实现排水以及脱水,也是一个需要被解决的技术问题。
有鉴于此,特提出本发明。
发明内容
为了解决上述问题,本发明的第一发明目的是提供一种滚筒洗衣机的控制方法,具体地,采用了如下的技术方案:
一种滚筒洗衣机的控制方法,洗衣机包括内筒,洗涤衣物时内筒内盛放洗涤水,内筒的侧壁上开设排水孔,排水孔上安装控制其导通/关闭的离心阀,其特征在于,控制方法包括:洗衣机洗衣过程中,通过控制内筒转速达到或者超过设定转速N0,离心阀受到离心力将排水孔打开进行内筒排水。
进一步地,洗衣机执行完洗涤程序或者漂洗程序后,控制内筒转速达到第一转速 N1并维持一设定时间t1,所述的N1≥N0,N0大于洗涤程序或者漂洗程序中內筒的转速;当内筒保持转速N1转动时间达到t1时,控制内筒停止转动进入下一程序;

进一步地,洗衣机包括用于称重内筒内重量的称重装置,称重装置检测内筒开始以N1转动之前的内筒内的重量W0,当转动时间达到t1后称重装置检测内筒内的重量W1,控制系统根据W1与W0比较判断是否排水正常。
进一步地,控制系统通过比较W1/W0的值k判断排水是否异常,若k≥0.7,则控制系统判断为排水异常并报警,否则,则排水正常。
进一步地,洗衣机执行完洗涤程序或者漂洗程序后,控制内筒转速达到第一转速N1,所述的N1≥N0,N0大于洗涤程序或者漂洗程序中內筒的转速;当内筒内的水排完后,控制内筒停止转动进入下一程序。
进一步地,洗衣机包括用于称重内筒内重量的称重装置,在洗衣机控制内筒以N1保持转动的过程中,控制系统根据称重装置实时检测的内筒内的重量值判断是否排水完成。
进一步地,控制系统根据称重装置实时检测的内筒内的重量值判断是否排水完成包括:
称重装置实时检测的内筒内的重量值W0、W1、W2、……、Wt;
将相邻时间的称重值做差,记n1=W1-W0,n2=W2-W1,……,nt=(Wt)-(Wt-1);
当nt在一定时间内保持不变且趋于0时,则排水完成。
进一步地,控制系统通过比较n1、n2、……、nt的变化情况判断排水是否正常,若n1=n2=……=nt=0,则控制系统判断排水异常并报警。
进一步地,洗衣机执行脱水程序,所述脱水程序中的最低脱水转速N2大于等于N0。
本发明的第二发明目的是提供一种采用所述控制方法的滚筒洗衣机。
本发明提供一种无孔内筒前开式结构的滚筒洗衣机,结构简单,能够无需在内筒与外筒之间填充洗涤/漂洗水而极大的减少了洗衣机的洗涤用水量。避免了内筒与外筒之间污垢附着的可能。极大的提高了用户健康及用户体验,极大的节约了水资源。
本发明的排水装置采用离心阀,控制方法通过控制内筒转动产生离心力将离心阀打开实现排水,通过离心阀+程序控制的方式实现了无孔内筒的滚筒洗衣机的排水以及脱水。

一种滚筒洗衣机的控制方法,洗衣机包括内筒,洗涤衣物时内筒内盛放洗涤水,内筒的侧壁上开设排水孔,排水孔上安装控制其导通/关闭的离心阀,控制方法包括:洗衣机洗衣过程中,通过控制内筒转速达到或者超过设定转速N0,离心阀受到离心力将排 水孔打开进行内筒排水。
本实施例的排水装置采用离心阀,控制方法通过控制内筒转动产生离心力将离心阀打开实现排水,通过离心阀+程序控制的方式实现了无孔内筒的滚筒洗衣机的排水以及脱水。
作为本实施例的一种实施方式,洗衣机执行完洗涤程序或者漂洗程序后,控制内筒转速达到第一转速N1并维持一设定时间t1,所述的N1≥N0,N0大于洗涤程序或者漂洗程序中內筒的转速;当内筒保持转速N1转动时间达到t1时,控制内筒停止转动进入下一程序;
优选地,N1为110-400转/分钟,更优选的为170±50转/分钟,进一步选优的为150±20转/分钟;
优选地,t1范围在0.1-5分钟之间,更优选的在1-2分钟。
进一步地,洗衣机包括用于称重内筒内重量的称重装置,称重装置检测内筒开始以N1转动之前的内筒内的重量W0,当转动时间达到t1后称重装置检测内筒内的重量W1,控制系统根据W1与W0比较判断是否排水正常。
进一步地,控制系统通过比较W1/W0的值k判断排水是否异常,若k≥0.7,则控制系统判断为排水异常并报警,否则,则排水正常。
作为本实施例的又一种实施方式,洗衣机执行完洗涤程序或者漂洗程序后,控制内筒转速达到第一转速N1,所述的N1≥N0,N0大于洗涤程序或者漂洗程序中內筒的转速;当内筒内的水排完后,控制内筒停止转动进入下一程序。
进一步地,洗衣机包括用于称重内筒内重量的称重装置,在洗衣机控制内筒以N1保持转动的过程中,控制系统根据称重装置实时检测的内筒内的重量值判断是否排水完成。
进一步地,控制系统根据称重装置实时检测的内筒内的重量值判断是否排水完成包括:
称重装置实时检测的内筒内的重量值W0、W1、W2、……、Wt;
将相邻时间的称重值做差,记n1=W1-W0,n2=W2-W1,……,nt=(Wt)-(Wt-1);
当nt在一定时间内保持不变且趋于0时,则排水完成。
进一步地,控制系统通过比较n1、n2、……、nt的变化情况判断排水是否正常,若n1=n2=……=nt=0,则控制系统判断排水异常并报警。
进一步地,洗衣机执行脱水程序,所述脱水程序中的最低脱水转速N2大于等于N0。
如图33所示,本实施例的一种采用所述控制方法的滚筒洗衣机。
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。
