Description

一种多滚筒洗衣机排水-脱水控制方法 技术领域
本发明属于洗涤领域的一种洗衣机以及一种洗衣机的控制方法,该洗衣机具有基于衣服的量和类型按照不同的方式清洗衣物的多个洗涤筒,还涉及该多筒洗衣机对洗涤水进行排水-脱水的控制方法。
背景技术
洗衣机执行清洗、漂洗和甩干-脱水的操作,以便利用洗涤剂与水的相互作用来清除附着在衣物上的污渍。烘干机作为另一有代表性的衣物处理装置,是用于烘干湿的服装等的家电用品。近来,具有洗衣机和烘干机的组合功能的家电用品已得到广泛使用。
随着人们生活质量的提高,卫生意识也逐渐提高,尤其在家庭衣物洗涤方面,越来越多的人将衣物分开洗涤。如果用现有洗衣机采取多次洗衣的方式,在洗涤时间上难以满足要求;如果购买两台或多台洗衣机分开同时洗涤,不仅会带来能源和水资源的极大浪费,而且占据空间大,不适于家庭使用。因此,用多筒洗衣机即可满足上述需要,解决能源和水以及空间的浪费问题。
合理的双筒设计为上下排列,便于节省空间,但随之带来的是整机使用功率的控制,尤其在同时进行加热、烘干及高速脱水的时候,会出现过载情况,严重影响机器的使用稳定性和寿命。
如申请号为CN200880124154.4的中国专利,其控制方法强调两筒执行同一程序是交替或顺序进行。但是,由于双筒洗衣机的洗涤程序不同,会使得两个洗涤筒的洗涤、漂洗时间不同。若其中一个洗涤筒的洗涤程序所需时间较长,会导致该洗涤筒执行洗涤程序时,另一洗涤筒已经正在执行脱水、烘干程序的步骤。这样,同样会导致两个洗涤筒同时执行大功率程序情况的发生。
还有,具有多个洗涤筒的洗衣机在工作过程中,若两个洗涤筒同时执行排水,就会导致两个洗涤筒的共用排水管出水流量过大,甚至会造成排水不及时及水流倒灌情况的发生。
另外,现有只具有一个洗涤筒的洗衣机普遍在洗涤程序或漂洗程序结束后,都会执行对应的脱水程序,以提高衣物的洗涤洁净度;而现有技术当中对多滚筒洗衣机的排水 -脱水程序控制部分的描述还不够全面,尤其是二者的衔接逻辑上没有涉及。
有鉴于此,特提出本发明。
发明内容
本发明的目的在于提供一种多滚筒洗衣机排水-脱水控制方法,使得多滚筒洗衣机可独立、稳定地执行排水程序和脱水程序。
本发明解决上述技术问题所采用的具体技术方案是:
一种多滚筒洗衣机排水-脱水控制方法,该洗衣机至少包括第一洗涤筒和第二洗涤筒,第一洗涤筒执行排水程序或脱水程序前,判断第二洗涤筒是否正在执行排水程序或脱水程序;若是,第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水,脱水至第二洗涤筒脱水完毕;若否,第一洗涤筒启动排水程序和脱水程序。
进一步,第一洗涤筒执行排水程序或脱水程序前,第二洗涤筒正在执行排水程序或脱水程序,则第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水程序或脱水程序,等第二洗涤筒脱水程序执行完毕,第一洗涤筒再启动排水程序和脱水程序。
进一步,第一洗涤筒执行排水程序或脱水程序前,第二洗涤筒正在执行排水程序,则第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水程序或脱水程序,等第二洗涤筒排水程序和脱水程序执行完毕,第一洗涤筒再启动排水程序和脱水程序。
进一步,第一洗涤筒执行排水程序或脱水程序前,第二洗涤筒正在执行脱水程序,则第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水程序或脱水程序,等第二洗涤筒脱水程序执行完毕,第一洗涤筒再启动排水程序和脱水程序。
进一步,第一洗涤筒继续执行洗涤程序或漂洗程序时,需判断第二洗涤筒距离脱水程序结束的剩余时间是否小于最短间隔时间;若是,第一洗涤筒停止执行洗涤程序或漂洗程序;若否,第一洗涤筒继续执行洗涤程序或漂洗程序。
进一步,第一洗涤筒继续执行洗涤程序或漂洗程序时,需判断第二洗涤筒距离脱水程序结束的剩余时间是否小于最短间隔时间;若是,第一洗涤筒继续执行洗涤程序或漂洗程序;若否,第一洗涤筒停止执行洗涤程序或漂洗程序。
优选的,所述的最短间隔时间不大于脱水程序所需总时间的四分之一。
进一步,当第一洗涤筒执行排水程序时,第二洗涤筒不能同时执行排水程序或脱水程序;当第一洗涤筒执行脱水程序时,第二洗涤筒不能同时执行排水、加热、脱水和烘干程序中的任一程序。
进一步,当第一洗涤筒执行排水程序或脱水程序前,需判断第二洗涤筒是否正在执 行排水程序、加热程序、脱水程序和烘干程序中的任一程序;若是,第一洗涤筒暂缓执行排水程序或脱水程序,第二洗涤筒继续执行正在运行的程序;若否,第一洗涤筒启动排水程序或脱水程序。
进一步,第一洗涤筒执行完排水程序后,直接执行脱水程序,以使得同一洗涤筒的排水程序和脱水程序连续不间断地执行,以减少衣物与洗涤水的接触时间。
进一步,第一洗涤筒执行排水或脱水程序时,先判断第二洗涤筒是否正在工作;若否,第一洗涤筒直接执行排水程序;若是,判断第二洗涤筒是否正在执行排水程序或脱水程序。
本发明的有益效果如下:
1、洗衣机的第一洗涤筒和第二洗涤筒顺序执行排水-脱水程序,以避免洗衣机的两个洗涤筒同时执行排水程序造成排水慢或上洗涤筒水流倒灌进下洗涤筒;或同时执行脱水程序、同时执行大功率程序情况的发生;
2、洗衣机的第一洗涤筒和第二洗涤筒分别依次顺序的、连续的执行排水程序和脱水程序,以避免排水程序后间隔一定时间再执行脱水程序,造成衣物上附带洗涤水时间过长,影响衣物洗涤洁净度;
3、在洗衣机的第一洗涤筒执行排水-脱水程序前需要等待时,令第一洗涤筒继续执行上一步的、对应的洗涤程序或漂洗程序,以合理利用等待时间,增加衣物的洗涤时间;同时,避免等待过程中衣物在洗涤筒中下沉,造成洗涤水中的污渍附着在衣物上,影响衣物洗涤洁净度;
4、在洗涤筒执行脱水程序前,判断另一洗涤筒是否正在执行大功率程序,以避免两筒同时执行大功率程序,并减小洗衣机的瞬时功率,提高双筒洗衣机的适用用电环境;
同时,本发明的加热控制方式简单可靠,效果显著,适宜推广使用。
附图说明
下面结合附图对本发明进行具体说明。
图1是本发明的多滚筒洗衣机结构示意图;
图2是本发明的排水-脱水过程流程图;
图3是本发明另一实施例的多滚筒洗衣机脱水过程流程图;
图4是本发明的进水-补水过程流程图;
图5是本发明的水重用过程流程图。
具体实施方式
如图1所示,一种多滚筒洗衣机,其至少设有可独立执行衣物洗涤步骤的第一洗涤筒1和第二洗涤筒2。第一洗涤筒1和第二洗涤筒2可分别独立的对衣物依次执行洗涤程序、漂洗程序、脱水程序,以达到对衣物进行洗涤的目的。优选的,所述多滚筒洗衣机还设有烘干装置,可以在脱水程序结束后,执行烘干程序,对第一洗涤筒1和/或第二洗涤筒2中的衣物进行烘干。
本发明中,第一洗涤筒1内设有对其内洗涤水进行加热的第一加热器,第二洗涤筒2内设有对其内洗涤水进行加热的第二加热器。从而,在执行洗涤程序过程中,各加热器分别对对应洗涤筒中的洗涤水进行加热处理,以控制衣物洗涤过程中的水温。
但是,由于普遍家庭用电缆可承受的电流较小,若第一洗涤筒和第二洗涤筒同时进行工作,会产生较大负荷的瞬时电流,导致用户家庭配电箱跳闸、甚至导致电缆烧损情况的发生。因此,需要将双筒洗衣机的两筒大功率程序设于不同阶段执行,以避免瞬时大电流情况的发生。所述的大功率程序包括,加热程序、脱水程序和烘干程序等。
为了避免洗衣机加热时,产生瞬时大电流,需要在第一洗涤筒执行脱水程序时,第二洗涤筒不可同时执行加热、脱水和烘干程序中的任一程序,以避免洗衣机两筒同时执行大功率程序情况的发生。
同时,由于洗衣机的第一洗涤筒和第二洗涤筒共用同一排水管路,若第一洗涤筒和第二洗涤筒同时排水,会导致排水管路中的水流量骤升,导致洗衣机排水不顺畅、甚至排水自地漏处溢流情况的发生。因此,需要将双筒洗衣机的排水程序交错设置,以避免同时排水情况的发生。
实施例一
本实施例中介绍了一种多滚筒洗衣机排水-脱水控制方法如下:
第一洗涤筒启动排水程序前,判断第二洗涤筒是否正在执行排水程序或脱水程序;若是,第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水,脱水至第二洗涤筒脱水完毕;若否,第一洗涤筒启动排水程序和脱水程序。
本实施例中,第一洗涤筒启动排水程序前,第二洗涤筒正在执行排水程序;则第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水程序或脱水程序,等第二洗涤筒排水程序和脱水程序执行完毕,第一洗涤筒再启动排水程序和脱水程序。
本实施例中,第一洗涤筒执行排水程序前,第二洗涤筒正在执行脱水程序,则第一 洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水程序或脱水程序,等第二洗涤筒脱水程序执行完毕,第一洗涤筒再启动排水程序和脱水程序。
还有,本实施例中,在洗衣机工作过程中,第一洗涤筒因用户操作或断电等情况导致停止工作后,第一洗涤筒再开始继续执行排水程序或脱水程序时,需判断第二洗涤筒是否正在执行排水程序或脱水程序;若是,第一洗涤筒继续执行洗涤程序或漂洗程序,或暂停执行排水,脱水至第二洗涤筒脱水完毕;若否,第一洗涤筒启动排水程序和脱水程序。
如图2所示,本实施例中,多滚筒洗衣机的排水-脱水控制方法具体如下:
1)、第一洗涤筒执行洗涤程序或漂洗程序结束、启动排水程序或脱水程序前;
2)、判断第二洗涤筒是否正在工作;
若是,执行步骤3);若否,执行步骤7);
3)、判断第二洗涤筒是否正在执行排水程序;
若是,执行步骤5);若否,执行步骤4);
4)、判断第二洗涤筒是否正在执行脱水程序;
若是,执行步骤5);若否,执行步骤7);
5)、第一洗涤筒继续执行洗涤程序或漂洗程序;并判断第二洗涤筒是否执行完排水程序;若是,执行步骤6);
6)、判断第二洗涤筒是否执行完排水程序脱水程序;若是,执行步骤7);
7)、第一洗涤筒启动排水程序和脱水程序。
本实施例中,存在如下特殊情况:
特殊情况1、第一洗涤筒需要执行排水程序或脱水程序,而第二洗涤筒将要完成脱水程序。此时需要判断第二洗涤筒距离脱水程序结束剩余时间是否小于最短间隔时间。
因此,在本实施例的上述步骤1)至7)的基础上,增加如下步骤:
在步骤5)前,增加如下判断:判断第二洗涤筒距离脱水程序结束剩余时间是否小于最短间隔时间;若是,第一洗涤筒停止执行洗涤程序或漂洗程序;若否,第一洗涤筒继续执行洗涤程序或漂洗程序;
或者,第一洗涤筒继续执行洗涤程序或漂洗程序,需判断第二洗涤筒距离脱水程序结束剩余时间是否小于最短间隔时间;若是,第一洗涤筒继续执行洗涤程序或漂洗程序;若否,第一洗涤筒停止执行洗涤程序或漂洗程序。
优选的,所述的最短间隔时间不大于脱水程序所需总时间的四分之一。
特殊情况2、当第一洗涤筒需要执行脱水程序,而第二洗涤筒正在执行加热程序或烘干程序。若第一洗涤筒启动脱水程序,就会导致两个洗涤筒同时执行大功率程序,造成洗衣机瞬时功率大,对洗衣机造成损坏。
因此,在本实施例的上述步骤1)至7)的基础上,增加如下步骤:
在步骤7)之前增加如下判断:判断第二洗涤筒是否正在执行排水程序、加热程序、脱水程序和烘干程序中的任一程序;若是,第一洗涤筒暂缓执行排水程序,等第二洗涤筒执行完正在运行的程序后,再启动排水程序(在等待过程中,第一洗涤筒可以继续执行洗涤程序或漂洗程序);若否,第一洗涤筒直接启动排水程序。
本实施例中,当第一洗涤筒执行排水程序时,第二洗涤筒不能同时执行排水程序或脱水程序;当第一洗涤筒执行脱水程序时,第二洗涤筒不能同时执行排水、加热、脱水和烘干程序中的任一程序。通过上述控制方法,洗衣机的第一洗涤筒和第二洗涤筒顺序执行排水-脱水程序,以避免洗衣机的两个洗涤筒同时执行排水程序造成排水慢或上洗涤筒水流倒灌进下洗涤筒或同时执行脱水程序、同时执行大功率程序情况的发生。
本实施例中,第一洗涤筒执行完排水程序后,直接启动脱水程序。洗衣机的第一洗涤筒和第二洗涤筒分别依次顺序的、连续的执行排水程序和脱水程序,以避免排水程序后间隔一定时间再执行脱水程序情况的发生,造成衣物上附带洗涤水时间过长,影响衣物洗涤洁净度情况的发生。
实施例二
如图3所示,本实施例所述多筒洗衣机的排水控制方法,第一洗涤筒到达排水程序时,判断第二洗涤筒此时是否正在脱水,若正在脱水,则第一洗涤筒等待第二洗涤筒脱水完成后排水;所述第一洗涤筒内的水起到了配重的作用,可以增加洗衣机的重量,实现减震的效果。
若第二洗涤筒此时没有脱水,则判断是否等待至脱水完成后再排水。可以避免第一洗涤筒刚排完水,第二洗涤筒就开始脱水的情况下,第一洗涤筒的水起不到减震的效果,造成浪费。
判断是否等待至脱水完成后再排水的过程:确定第二洗涤筒距离脱水的时间为T32,确定第二洗涤筒脱水所用时间为T33,设定一允许的等待时间T3,若T32<T3-T33,说明在允许等待的时间范围内,则第一洗涤筒等待第二洗涤筒脱水完成后排水,否则第一洗涤筒的水直接排掉。
由于第一洗涤筒和第二洗涤筒的排水口通过管路连接至洗衣机的排水口,整个洗衣机只有一个排水口,两个洗衣机同时排水,由于压力差可能造成洗涤水回流,造成衣物污染,而共用一个排水管,同时排和分别排的速度实质上是一样的,所以第一洗涤筒和第二洗涤筒不能同时排水,第一洗涤筒即将排水时,判断第二洗涤筒此时是否正在排水,若第二洗涤筒此时正在排水,则第一洗涤筒等待第二洗涤筒排水结束后排水,否则第一洗涤筒的水直接排掉。
为了对第一洗涤筒内的水重复利用,第一洗涤筒到达排水程序时,判断第一洗涤筒的水是否可以重复利用,若否,第一洗涤筒的水直接排走,若是,判断第二洗涤筒是否正在进水,若是,第一洗涤筒的水排入第二洗涤筒,水重复利用;若否,判断第一洗涤筒是否等待至第二洗涤筒进水。
判断第一洗涤筒是否等待至第二洗涤筒进水的过程:比较第二洗涤筒到达进水程序的时间T12和第一洗涤筒到达下次排水程序的时间T11,若T12<T11,第一洗涤筒等待第二洗涤筒进水,第一洗涤筒的水排入第二洗涤筒,水重复利用,若T12≥T11,第一洗涤筒的水直接排走。
上述判断过程可能造成等待时间较长,此时可以设定一允许的等待时间T1,T1<T11,若T12<T1,说明在允许等待的时间范围内,第一洗涤筒等待第二洗涤筒进水,第一洗涤筒的水排入第二洗涤筒,水重复利用,若T12≥T1,说明不在允许等待的时间范围内第一洗涤筒的水直接排走。
判断第一洗涤筒的水是否可以重复利用时,检测第一洗涤筒内的水的浊度值或泡沫浓度值,若浊度值或泡沫浓度值小于设定值,第一洗涤筒的水可以重复利用,否则第一洗涤筒的水不可以重复利用,直接将水排走。
第一洗涤筒到达排水程序时,判断第二洗涤筒正在进行的或者即将进行的是否是最后一次漂洗进水,若是,第一洗涤筒的水直接将水排走,若否,继续判断第一洗涤筒的水是否可以重复利用。
第一洗涤筒和第二洗涤筒只是为了方便说明编的号,不分顺序关系,还可以第二洗涤筒排水时,判断第一洗涤筒此时是否正在脱水,若正在脱水,则第二洗涤筒等待第一洗涤筒脱水完成后排水;所述第二洗涤筒内的水起到了配重的作用,可以增加洗衣机的重量,实现减震的效果。
若第一洗涤筒此时没有脱水,则判断是否等待至脱水完成后再排水。可以避免第二 洗涤筒刚排完水,第一洗涤筒就开始脱水的情况下,第二洗涤筒的水起不到减震的效果,造成浪费。

实施例三
本发明中,第一洗涤筒1和第二洗涤筒2经管路与同一进水管路相连通,管路上设有控制水流通断的控制装置。从而,在执行洗涤过程前,可经进水管路相第一洗涤筒和/或第二洗涤筒中注入洗涤水。
但是,由于家庭用进水管路的进水流速恒定,在第一洗涤筒和第二洗涤筒同时进水时,会导致进水流速较小,第一洗涤筒和第二洗涤筒未达到设定水位情况的发生;还会导致进水流速不稳定,无法准确判定第一洗涤筒和第二洗涤筒中洗涤水的水位的问题。
本发明为了避免出现上述情况,在第一洗涤筒和第二洗涤筒执行洗涤程序过程中,持续或者定时对筒内水量或水位进行监控,以对筒内进水量不足、和因衣物充分吸水后而导致的水位降低问题进行改善,及时补充洗涤用水。
同时,当第一洗涤筒执行进水程序时,第二洗涤筒不能同时执行进水和补水程序中的任一程序;同样,当第二洗涤筒执行进水程序时,第一洗涤筒不能同时执行进水和补水程序中的任一程序。从而,避免两筒同时进水情况的发生。
本实施例中介绍了一种多筒洗衣机补水控制方法如下,
第一洗涤筒执行进水程序和补水程序时,需要判断第二洗涤筒是否正在执行进水程序或补水程序,以避免两个洗涤筒同时执行进水或补水情况,造成洗涤筒进水量不足。
如图4所示,本实施例中,多滚筒洗衣机进水-补水控制方法如下:
1)、第一洗涤筒执行进水程序前;
2)、判断第二洗涤筒是否正在执行进水程序;
若是,执行步骤4);若否,执行步骤3);
3)、判断第二洗涤筒是否正在执行补水程序;
若是,执行步骤4);若否,执行步骤5):
4)、第一洗涤筒停止执行进水程序,至第二洗涤筒进水或补水程序完成后,执行步骤5);
5)、第一洗涤筒执行进水程序,至进水完成;
6)、第一洗涤筒执行洗涤程序;
7)、洗涤过程中,若第一洗涤筒中的洗涤水水位低于设定水位,则执行步骤8);
8)、第一洗涤筒执行补水程序;
9)、判断第二洗涤筒是否正在执行进水程序;
若是,执行步骤13);若否,执行步骤10);
10)、判断第二洗涤筒是否正在执行补水程序;
若是,执行步骤11);若否,执行步骤12):
11)、第一洗涤筒停止执行补水程序,至第二洗涤筒补水程序完成后,执行步骤12);
12)、第一洗涤筒执行补水程序,至第一洗涤筒中的洗涤水达到设定水位后,终止补水程序;
13)、第二洗涤筒停止执行进水程序、第一洗涤筒执行补水程序,至第一洗涤筒中的洗涤水达到设定水位后,第二洗涤筒恢复执行进水程序。
本实施例中,所述的设定水位是第一洗涤筒执行的洗涤程序所对应的设定值。当第一洗涤筒执行进水程序时,第二洗涤筒不能同时执行进水或补水程序。第一洗涤筒的进水程序完成条件为,第一洗涤筒中的洗涤水水位达到设定水位。
本实施例中,所述的第一洗涤筒和第二洗涤筒的补水控制方法相同;即可将步骤1)至13)中的第一洗涤筒和第二洗涤筒的位置进行调换,就得出第二洗涤筒的补水控制方法。
本实施例中,上述控制步骤1)至13)中,还存在如下特殊情况:
特殊情况1、当第一洗涤筒正在执行进水程序时,若第二洗涤筒需要执行补水程序,则第一洗涤筒等待,第二洗涤筒正常执行补水程序;至第二洗涤筒补水结束后,第一洗涤筒再执行进水程序。从而,使得洗涤用时短的洗涤筒优先工作,缩减用户等待时间,提高整机人性化程度。
特殊情况2、当第一洗涤筒正在执行补水程序时,若第二洗涤筒需要执行补水程序,则依据顺序原则,第二洗涤筒优先执行补水程序;至第二洗涤筒补水结束后,第一洗涤筒再执行补水程序。从而,使得第二洗涤筒和第一洗涤筒的进水-补水不会交替发生,减少进水阀的开闭次数,利于洗衣机控制程序的简化。
还有,洗衣机在任一时间节点只能发出一条进水指令或补水指令,该指令只能控制第一洗涤筒和第二洗涤筒中的一个执行进水程序或补水程序。从而,使得,洗衣机的控制单元在同一时刻只能向第一洗涤筒或第二洗涤筒发出进水或补水的指令,避免第一洗涤筒和第二洗涤筒同时执行进水或补水程序情况的发生。
在第一洗涤筒和第二洗涤筒中分别设有检测洗涤水水位的传感器。在第一洗涤筒或第二洗涤筒开始执行进水程序时,进水阀保持开启状态,直至传感器检测到洗涤水达到设定水位后,进水阀闭合,进水程序完成。在第一洗涤筒或第二洗涤筒洗涤过程中洗涤水水位低于设定值后,在第一洗涤筒或第二洗涤筒开始执行补水程序,进水阀保持开启状态,至传感器检测到洗涤水达到设定水位后,进水阀闭合,补水程序完成。
本实施例中,第一洗涤筒和第二洗涤筒是否正在执行进水程序或补水程序的判断条件是,第一洗涤筒和第二洗涤筒的对应进水阀是否开启。
进水阀是否开启的判断方式为,进水阀上一次接收到的指令为开启指令时,判断进水阀为开启状态;上一次接收到的指令为闭合指令时,判断进水阀为闭合状态。第一洗涤筒或第二洗涤筒上设的水位传感器检测到洗涤水水位低于设定水位后,第一洗涤筒或第二洗涤筒需要开始执行进水程序或补水程序;此时,开始执行本实施例中步骤1)至步骤13)的相关步骤,以判断第一洗涤筒或第二洗涤筒是否开始执行进水或补水程序。当第一洗涤筒或第二洗涤筒需要开始执行进水或补水程序时,洗衣机的控制单元向对应进水阀发出开启信号,进水阀处于开启状态;进水或补水过程中,水位传感器检测到对应洗涤筒中洗涤水水位达到设定水位后,向对应进水阀发出闭合信号,进水阀处于闭合状态。
或者,进水阀是否开启的判断方式为,判断是否有水流经对应进水阀;当有水流经 进水阀时,进水阀为开启状态;当没有水流经进水阀时,进水阀为闭合状态。第一洗涤筒和第二洗涤筒的进水阀上分别设有检测流经对应进水阀水流量的流量传感器。当流量传感器检测到有洗涤水流经后,判断对应进水阀为开启状态;否则,判断对应进水阀为闭合状态。
或者,进水阀是否开启的判断方式为,判断进水阀的开启时间是否达到设定时间;当进水阀的开启时间达到设定时间时,进水阀为闭合状态;当进水阀的开启时间未达到设定时间时,进水阀为开启状态。洗衣机上设有计时器,当进水阀接收到开启信号后,计时器开始计时,在计时时间未达到设定时间前,进水阀始终处于开启状态;当计时时间达到设定时间后,进水阀处于闭合状态。
本实施例中,优选的,第一洗涤筒的进水阀和第二洗涤筒的进水阀上设有相互锁定的互锁装置,以使得第一洗涤筒的进水阀处于开启状态时,第二洗涤筒的进水阀无法打开;第二洗涤筒的进水阀处于开启状态时,第一洗涤筒的进水阀无法打开。从而,避免第一洗涤筒和第二洗涤筒的进水阀同时开启情况的发生。当然,还互锁装置还具有第三种状态:第一洗涤筒和第二洗涤筒的进水阀均处于闭合状态。
实施例四
本实施例中,为了节约洗衣机的用水量,将多滚筒洗衣机的第一洗涤筒与第二洗涤筒相连通,可以使得第一洗涤筒排出的、满足洁净度的洗涤水可做为进水或补水水源流入第二洗涤筒中重新利用;还可以使得第二洗涤筒排出的、满足洁净度的洗涤水可做为进水或补水水源流入第一洗涤筒中重新利用。
因此,需要在上述实施例三的基础上增加如下判断:在执行实施例三中的步骤2)之前,需判断第二洗涤筒是否正在或将要执行排水程序;若否,第一洗涤筒以净水为水源直接执行进水程序或补水程序;若是,判断第二洗涤筒中的洗涤水是否可以重复利用;若是,第一洗涤筒暂缓执行进水程序或补水程序,至第二洗涤筒开始排水时,第二洗涤筒中的洗涤水做为进水或补水水源流入第一洗涤筒中。
本实施例中,第二洗涤筒是否将要执行排水程序的判断条件为,第二洗涤筒距离执行下次排水程序的剩余时间是否小于设定时间;若是,第一洗涤筒暂缓执行进水程序或补水程序,至第二洗涤筒开始排水时,第二洗涤筒中的洗涤水流入第一洗涤筒中重复利用;若否,第二洗涤筒直接进净水。
本实施例中,第二洗涤筒中的洗涤水是否可以重复利用的判断条件为,检测第二洗 涤筒内水的浊度值或泡沫浓度值,若浊度值或泡沫浓度值小于设定值,第二洗涤筒的水可以重复利用,否则第二洗涤筒的水不可以重复利用。
实施例五
如图5所示,本实施例采用进水等待时间为判断标准,判断是否进行水的重复利用,根据进水等待时间来判定是否在到达进水程序时等待另一筒排水时进行重复使用,具有简单的判断和控制逻辑,在实际洗涤程序中控制稳定性较高。同时,实现水的充分重复利用,实用价值高,更能有效地推广应用。
本实施例中的进水是否重复利用的判断,可以与实施例五中所述的进水-补水程序步骤的判断相结合,以判定洗涤筒的外排水是否可作为另一洗涤筒的进水或补水水源重新使用,达到洗涤水重复利用的目的。
第一洗涤筒和第二洗涤筒同时处于工作状态时,水重复利用的控制方法如下:
一种多筒洗衣机水重复利用的控制方法,所述多筒洗衣机至少包括第一洗涤筒和第二洗涤筒,第一洗涤筒和第二洗涤筒同时处于工作状态时,水重复利用的控制方法如下:第一洗涤筒到达进水程序时,比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21,若T22≥T21,第一洗涤筒直接进净水,若T22<T21,第一洗涤筒等待至第二洗涤筒排水。
比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21,之前,判断第二洗涤筒的水是否可以重复利用,若否,第一洗涤筒直接进净水,若是,比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21;或者第一洗涤筒等待至第二洗涤筒排水时,判断第二洗涤筒的水是否可以重复利用,若否,第一洗涤筒直接进净水,若是,第二洗涤筒的水排入第一洗涤筒重复利用。
具体:步骤1:第一洗涤筒到达进水程序,比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21,若T22≥T21,第一洗涤筒直接进净水,若T22<T21,第一洗涤筒等待至第二洗涤筒排水,执行步骤2;
步骤2:判断第二洗涤筒的水是否可以重复利用,若是,第二洗涤筒的水排入第一洗涤筒重复利用,若否,第一洗涤筒直接进净水。增加判断是否等待的过程,很大范围增加了第二洗涤筒的水重复利用的几率,更多的水能够重复利用。
步骤1中,第一洗涤筒到达进水程序时若第二洗涤筒正在排水,则第二洗涤筒到达排水程序的时间T22为0,无需等待,直接进行步骤2。也可以在比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21之前,先判断第二洗涤筒此时是否正在执行排水程序,如果第二洗涤筒没有进行排水程序时,再进行比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21
步骤1中,设定一允许的等待时间T2,T2<T21,若T22<T2,第一洗涤筒等待至第二洗涤筒排水,执行步骤2,若T22≥T2,第一洗涤筒直接进净水。该步骤可以避免第一洗涤筒等待太长时间,在保证第一洗涤筒的洗涤时间的前提下合理安排水的重复利用,不会因为只考虑重复用水,浪费第一洗涤筒的太多的时间,洗衣机如果判断等待的时间过长,超过了设定的允许等待时间,则第一洗涤筒就不重复利用第二洗涤筒的水了,该判断将水的重复利用变的更合理,最大程度上协调了等待时间和水重复利用之间的关系。
步骤2中,检测第二洗涤筒内的水的浊度值或泡沫浓度值,若浊度值或泡沫浓度值小于设定值,第二洗涤筒的水可以重复利用,否则第二洗涤筒的水不可以重复利用。在水的浊度值或泡沫浓度值在设定范围内时,水才可以重新利用。
步骤1中,第一洗涤筒到达进水程序时,判断开始执行的进水程序是否是最后一次漂洗进水,若是,第一洗涤筒直接进净水,若否,继续比较第二洗涤筒到达排水程序的时间T22和第一洗涤筒到达下次进水程序的时间T21。保证最后一次漂洗进水进净水,保证衣物洗涤完成后的效果。
步骤2中,第二洗涤筒的水排入第一洗涤筒前,判断第一洗涤筒是否是执行洗涤进水程序,若是,第一洗涤筒先进行洗涤剂盒冲洗进水,第一洗涤筒洗涤剂盒冲洗进水结束后,再进行第二洗涤筒的水排入第一洗涤筒,若否,直接进行第二洗涤筒的水排入第一洗涤筒。
步骤2、中,第二洗涤筒的水排入第一洗涤筒时,检测第一洗涤筒内水位的高度,若当第一洗涤筒内水位到达设定水位值时,第二洗涤筒内还有水,将第二洗涤筒剩余水直接排走;若当第二洗涤筒内水全部排到第一洗涤筒内后,第一洗涤筒内水位还未达到设定水位值,第一洗涤筒进净水。
第二洗涤筒的水直接排走前,判断第一洗涤筒此时是否正在执行脱水程序,若是,第二洗涤筒等待第一洗涤筒脱水完成后排水,若否,确定第一洗涤筒距离脱水的时间为 T41,第一洗涤筒脱水所用时间为T44,设定一允许的等待时间T4,若T41+T44<T4,则第二洗涤筒等待第一洗涤筒脱水完成后排水,否则将第二洗涤筒的水直接排走。
也可以通过判断洗涤状态和洗涤次数来判断第一洗涤筒的水可以重复利用,步骤2中,若第二洗涤筒排水时处于洗涤状态且第一洗涤筒进水时处于漂洗状态,或者第二洗涤筒排水时和第一洗涤筒进水时均处于洗涤状态且第二洗涤筒的洗涤次数少于第一洗涤筒的洗涤次数,或者第二洗涤筒排水时和第一洗涤筒进水时均处于漂洗状态且第二洗涤筒的漂洗次数少于第一洗涤筒的漂洗次数,第一洗涤筒的水不可以重复利用。
当第二洗涤筒到达进水程序时,比较第一洗涤筒到达排水程序的时间和第二洗涤筒到达下次进水程序的时间,判断第二洗涤筒是否等待第一洗涤筒排水。
第二洗涤筒的排水口与第一洗涤筒的连通,第二洗涤筒内的水可以排到第一洗涤筒重复利用,第二洗涤筒的排水口处设有留水阀,第二洗涤筒的水可经过留水阀进入第一洗涤筒,第一洗涤筒的设有进水阀,外部净水可通过进水阀进入第一洗涤筒,所述控制方法如下:
