Description

一种滚筒洗衣机及其控制方法 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及其控制方法。
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。但是随着人们生活水平的提高，对于洗衣机的洗涤要求也越来越多，具体来说，由于不同类型的衣物不能混在同一洗涤筒内洗涤，再或者各家庭成员的衣物也不能混在同一洗涤筒内洗涤，导致了分区独立洗涤便成为一种需求。
为了解决分区独立洗涤的目的，现有申请号为201410806293.2，名称为：一种双筒滚筒洗衣机的中国发明专利，该发明创造提供一种双筒滚筒洗衣机，包括机壳、控制面板、第一容腔、第二容腔，所述第一容腔和第二容腔同心并且第二容腔半径小于第一容腔半径，所述控制面板可以控制第一容腔和第二容腔同时工作，也可以控制第一容腔和第二容腔分别独立工作。本发明创造的有益效果是，通过结构的巧妙设计不仅精简了洗衣机所占空间，而且实现了内衣与外衣，浅色衣物与深色衣物可以在一个洗衣流程中完成洗涤，节约能源消耗，满足不同衣物的洗涤要求，达到良好的洗涤效果。
上述发明专利的滚筒洗衣机虽然具有第一容腔和第二容腔来满足不同衣物的洗涤要求，但实质上第一容腔和第二容腔同时工作时，由于內筒上具有脱水孔，导致两个容腔相通，并不能实现两个容腔的独立分区洗涤。
另外，人们针对洗衣机的节水性以及自清洁性的要求也越来越高。
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，具体地，采用了如下的技术方案：

进一步地，所述的第二内筒为无孔筒，第二内筒的筒口上安装可开启/关闭的第二内筒门，第二内筒门关闭与无孔筒形成可封闭的独立洗涤腔室。
进一步地，所述的第二内筒的侧壁上开设第二排水口，所述的第二排水口上设置用于保持排水口常闭的第二离心阀，所述的第二离心阀在第二内筒的转速超过设定值时将第二排水口打开进行排水。
进一步地，包括进水系统，所述的第一内筒、第二内筒分别连通进水系统；
优选地，洗衣机包括连接第一内筒的底部的内筒轴，所述的内筒轴为中空轴，所述的进水系统包括进水管路，进水管路连通中空轴，所述的第一内筒、第二内筒均与中空轴连通。
进一步地，所述的第二内筒可拆卸的安装在第一内筒内部，且第二内筒上具有用于连通中空轴的连通口；
优选地，所述的第二内筒的筒底通过卡接结构卡接在第一内筒的筒底上，所述第二内筒的筒底中心位置处开设连通口。
进一步地，所述的第一内筒为无孔筒，第一内筒的筒口上安装可开启/关闭的第一内筒门，第一内筒门关闭与无孔筒形成可封闭独立的洗涤腔室。
进一步地，所述的第一内筒的侧壁上开设第一排水口，所述的第一排水口上设置用于保持排水口常闭的第一离心阀，所述的第一离心阀在第一内筒的转速超过设定值时将第一排水口打开进行排水。
进一步地，所述第一内筒的轴向高度H1大于第二内筒的轴向高度H2。
本发明的第二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，洗衣机控制第一内筒和/或第二内筒运行，对第一内筒或者第二内筒内的衣物进行分区独立洗涤。
进一步地，洗衣机执行第一内筒洗衣程序时，控制第一内筒转速超过第一设定值N1时，第一离心阀将第一排水口打开进行排水；

因此，本发明滚筒洗衣机可以实现由一个驱动电机驱动多种规格的内筒，实现其中一个内筒运转洗涤或者多个内筒同时洗涤,而外观仅仅一个洗衣机外观，真正实现一台洗衣机一个电机多个独立洗涤分区,轻松实现宝宝专属洗、内衣洗、老人衣物洗、袜子洗涤等分区洗涤的功能，提高了洗涤的效果，提升用户体验。

实施例四
本实施例主要解决无孔内筒滚筒洗衣机如何保证密封舱气压不平衡的问题,具体是,突然的电磁阀断水,尤其的是自来水管网断水,形成负压,将密封舱内的洗涤水回洗至管 网；或者内部有气体，进水困难的问题。

如图9所示意，进水时，内筒17的密封舱内的气体受压，一旦大于正压安全阀的设定值，正压安全阀打开，可以通过该泄压孔道溢出，保证气压平衡。
如图10所示意，突然断水时，内筒17的密封舱内的气体受压，一旦小于正压安全阀的设定值，外部大气可以迅速进入密封舱，并破坏倒吸，保证气压平衡，避免洗涤水被吸入自来水管网。
其他比如脱水时，该气压平衡机构也可以保证内筒气压平衡。
本实施例的滚筒洗衣机包括驱动电机16和内筒轴13，所述的驱动电机16通过内筒轴13与内筒17传动连接带动内筒17转动，所述的增压孔道28和/或泄压孔道30开设在内筒轴13上连通内筒17内部与外界环境，所述内筒17内的最高水位低于内筒轴13。

实施例五
如图13所示，本实施例的一种滚筒洗衣机，包括第一内筒1701和设置在第一内筒1701内部的第二内筒1702，所述的第二内筒1702具有可封闭的独立洗涤腔室，洗涤衣物时独立盛放洗涤水。
本实施例的滚筒洗衣机第一内筒1701作为独立的洗涤筒可以单独进行衣物洗涤，第二内筒1702具有可封闭的独立洗涤腔室，也可以作为独立的洗涤筒也可以单独进行衣物洗涤，又由于第二内筒1702具有可封闭的独立洗涤腔室，洗涤衣物时独立盛放洗 涤水，这样，在第一内筒1701和第二内筒1702同时洗涤时，两个筒内的水不会相互混合，从而实现了两个筒的同时独立分区洗涤。
因此，本发明滚筒洗衣机可以实现由一个驱动电机驱动多种规格的内筒，实现其中一个内筒运转洗涤或者多个内筒同时洗涤,而外观仅仅一个洗衣机外观，真正实现一台洗衣机一个电机多个独立洗涤分区,轻松实现宝宝专属洗、内衣洗、老人衣物洗、袜子洗涤等分区洗涤的功能，提高了洗涤的效果，提升用户体验。
为了实现第二内筒具有可封闭的独立洗涤腔室，所述的第二内筒1702为无孔筒，第二内筒1702的筒口上安装可开启/关闭的第二内筒门602，第二内筒门602关闭与无孔筒形成可封闭的独立洗涤腔室。
由于第二内筒1702采用无孔筒结构，为了实现第二内筒1702的排水，所述的第二内筒1702的侧壁上开设第二排水口，所述的第二排水口上设置用于保持排水口常闭的第二离心阀33，所述的第二离心阀33在第二内筒1702的转速超过设定值时将第二排水口打开进行排水。采用离心阀排水的结构设计，使得第二内筒1702在洗涤过程中，由于转速达不到离心阀的开启转速，使得第二内筒1702内的衣物进行独立洗涤，在排水或者脱水时，通过控制内筒1702的转速超过设定值将离心阀开启，实现排水。
由于第二内筒1702采用无孔筒设计，使得第二内筒1702即是洗涤筒又是盛水筒，为了实现第二内筒1702的进水，本实施例的滚筒洗衣机包括进水系统，所述的第一内筒、第二内筒分别连通进水系统。
优选地，洗衣机包括连接第一内筒1701的底部的内筒轴13，所述的内筒轴13为中空轴，所述的进水系统包括进水管路，进水管路连通中空轴，所述的第一内筒1701、第二内筒1702均与中空轴连通。
进一步地，本实施例所述的第二内筒1702可拆卸的安装在第一内筒内部，且第二内筒上具有用于连通中空轴的连通口。这样，用户可根据具体的洗涤情况选择是否利用第二内筒1702，提升用户的洗涤体验。
优选地，所述的第二内筒1702的筒底通过卡接结构卡接在第一内筒1701的筒底上，所述第二内筒1702的筒底中心位置处开设连通口。
本实施例的第一内筒可以为传统的有孔内筒，也可为无孔筒，为了进一步的提升本实施例滚筒洗衣机的节水性和自清洁性，本实施例所述的第一内筒1701为无孔筒，第一内筒1701的筒口上安装可开启/关闭的第一内筒门601，第一内筒门601关闭与无孔 筒形成可封闭独立的洗涤腔室。
与此同时，为了实现第一内筒的排水，所述的第一内筒1701的侧壁上开设第一排水口，所述的第一排水口上设置用于保持排水口常闭的第一离心阀32，所述的第一离心阀32在第一内筒1701的转速超过设定值时将第一排水口打开进行排水。
本实施例所述第一内筒1701的轴向高度H1大于第二内筒1702的轴向高度H2，从而使得本申请的洗衣机具有容积不同的两个内筒，用户可根据实际情况选择对应的内筒实现独立分区洗涤。
本实施例的一种滚筒洗衣机的控制方法，洗衣机控制第一内筒和/或第二内筒运行，对第一内筒或者第二内筒内的衣物进行分区独立洗涤。
进一步地，洗衣机执行第一内筒洗衣程序时，控制第一内筒转速超过第一设定值N1时，第一离心阀将第一排水口打开进行排水；
洗衣机执行第二内筒洗衣程序时，控制第二内筒转速超过第一设定值N2时，第二离心阀将第二排水口打开进行排水；
