Description

一种多筒洗衣机补水控制方法 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补水的控制方法。
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。
但随之带来的是整机运行控制的问题,尤其在洗涤过程中,不同滚筒所洗衣物不同,吸水能力不同,在进水时间有限的条件下,很容易会出现理论进水量远小于实际所需水量的情况。这样在洗涤加热时,就会出现干烧危险;并且洗涤水过少,衣物的洗涤效果也会大打折扣。本发明就是要解决优化洗涤进水的问题。
如申请号为CN200710005793.6的中国专利,该发明是提出双筒洗衣机进水的逻辑控制,主要讲明双筒洗衣机两个筒进水的逻辑先后关系。但是,上述方案仅仅是针对进水程序的判断进行的判定,在判定后,两个筒分别安装对应程序进水;而没有涉及进水完成后、洗涤过程中,洗涤水水量不足,需要再次补水的情况。
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筒洗衣机补水控制方法,使得多滚筒洗衣机可独立、稳定地执行加热程序。
本发明解决上述技术问题所采用的具体技术方案是:
一种多筒洗衣机补水控制方法,该洗衣机至少具有第一洗涤筒和第二洗涤筒,第一洗涤筒洗涤过程中,若洗涤水水位低于设定值,则执行补水程序,执行补水程序前,需判断第二洗涤筒是否正在执行补水程序;若是,第一洗涤筒暂停补水程序,第二洗涤筒优先执行补水程序;若否,第一洗涤筒执行补水程序,至第一洗涤筒中的洗涤水水位达到设定水位后终止补水程序。
进一步,当第一洗涤筒要执行进水程序,第二洗涤筒正在执行补水程序时,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,使得第二洗涤筒和第一洗涤筒的进水-补水不会交替发生,,避免进水阀开闭转换次数过多,造成洗衣机控制程序复杂化情况的发生。
进一步,当第一洗涤筒要执行补水程序,第二洗涤筒正在执行进水程序时,则第二洗涤筒等待,第一洗涤筒正常执行补水程序;至第一洗涤筒补水结束后,第二洗涤筒再执行进水程序。从而,使得洗涤用时较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。
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,直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。
进一步,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。
进一步,第一洗涤筒执行进水程序或补水程序前,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流入第一洗涤筒中。
进一步,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。
进一步,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。
进一步,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。
进一步,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。
进一步,第一洗涤筒执行进水和补水程序前,均需先判断第二洗涤筒是否正在工作运行中;若是,判断第二洗涤筒是否正在执行进水程序或补水程序;若否,第一洗涤筒正常执行对应的进水或补水程序。正在工作运行指正在执行进水程序、补水程序、洗涤程序、漂洗程序、排水程序、脱水程序、烘干程序等。
进一步,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。
进一步,在第一洗涤筒和第二洗涤筒执行进水程序和/或补水程序和/或洗涤程序过程中,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。
本发明的有益效果:
1、通过对洗涤筒执行进水或补水程序前判断另一洗涤筒是否正在执行进水或补水程序,以避免两个洗涤筒同时执行进水或补水情况的发生,提高进水和补水程序的平稳性;
2、在洗涤筒执行洗涤程序中,对洗涤筒中的洗涤水水位进行监测,以对因衣物吸水和/或进水程序过低情况导致的水量或水位水量或水位不足情况进行补水;
3、在洗涤筒执行进水或补水程序前,判断另一洗涤筒是否将要或正在执行排水,以实现洗涤水的二次重复利用;同时,对重用水进行水质检测,以保证洗涤水重复利用的可靠性;
4、本发明设计人性化且易实现,将洗涤剩余时间较短的洗涤筒优先执行补水程序,以缩短用户的等待时间;
同时,本发明的进水-补水控制方式简单可靠,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是本发明的多滚筒洗衣机洗涤加热过程流程图;
图3是本发明另一实施例的多滚筒洗衣机洗涤加热过程流程图;
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,可经进水管路向第一洗涤筒1和/或第二洗涤筒2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水位或进水量的问题。
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,当第一洗涤筒正在执行进水程序时,第二洗涤筒不能同时执行进水或补水程序;同样,当第二洗涤筒正在执行进水程序时,第一洗涤筒不能同时执行进水或补水程序。从而,避免两筒同时进水情况的发生。
实施例一
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的发生,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,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。
实施例二
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,需要在上述实施例一的基础上增加如下判断:在执行实施例一中的步骤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。
实施例三
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,可以与实施例一中所述的进水-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:
1)、第一洗涤筒到达进水程序,
2)、判断第二洗涤筒内的水是否重复利用,若是,执行步骤3),若否,执行步骤6),
3)、确定第一洗涤筒距离下次执行进水程序的时间为T21,确定第二洗涤筒距离执行排水程序的时间为T22,若T22<T21,执行步骤4),若T22≥T21,执行步骤6),
4)、第一洗涤筒等待第二洗涤筒排水,执行步骤5)
5)、第二洗涤筒内的水排入第一洗涤筒,
6)、第一洗涤筒直接进净水,第二洗涤筒的水直接排走。

本实施例中,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,还可以对第一洗涤筒的水进行重新利用。但是,两个洗涤筒不能同时执行上述步骤,以避免两个洗涤筒同时等待造成死循环情况的发生。
实施例四
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加热程序时,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。
本实施例中介绍了一种多滚筒洗衣机的加热控制方法如下:
在第一洗涤筒执行加热程序前,需先对第二洗涤筒的剩余加热时间与第一洗涤筒的剩余加热时间进行比较,剩余时间短的洗涤筒优先执行加热程序,剩余时间长的洗涤筒在优先执行的洗涤筒停止加热后,再继续执行加热程序。
如图2所示,本实施例中,多滚筒洗衣机的加热控制方法具体如下:
1)、第一洗涤筒执行加热程序前;
2)、判断第二洗涤筒是否正在执行加热程序;
若是,执行步骤3);若否,执行步骤4);
3)、判断第一洗涤筒的剩余加热时间T1和第二洗涤筒的剩余加热时间T2的大小;若T1>T2,执行步骤8);若T1<T2,执行步骤9);
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6);
5)、第一洗涤筒停止加热程序,至第二洗涤筒脱水完成,执行步骤6);
6)、判断第二洗涤筒是否正在执行烘干程序;
若是,执行步骤7);若否,执行步骤8);
7)、第一洗涤筒停止加热程序,至第二洗涤筒烘干完成,执行步骤8);
8)、第一洗涤筒停止加热程序,至第二洗涤筒加热完成,执行步骤10);
9)、第二洗涤筒停止加热程序,执行步骤11);
10)、第一洗涤筒执行加热程序,至第一洗涤筒加热完成;
11)、第一洗涤筒执行加热程序,至第一洗涤筒加热完成,第二洗涤筒再继续执行加热程序。
本实施例中,第一洗涤筒的加热时间是第一洗涤筒执行的洗涤程序所对应的设定值;第二洗涤筒的加热时间是第二洗涤筒执行的洗涤程序所对应的设定值。
本实施例中,所述的第一洗涤筒和第二洗涤筒的加热控制方法相同;即可将步骤1)至11)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加热控制方法。
本实施例中,第一洗涤筒或第二洗涤筒的加热时间为洗涤筒所执行洗涤程序的对应设定值;洗衣机对第一洗涤筒或第二洗涤筒的加热过程进行计时得出已加热时间;再依据,剩余加热时间=加热时间-已加热时间,得出第一洗涤筒或第二洗涤筒的剩余加热时间。
本实施例中,存在如下特殊情况:
特殊情况1、第一洗涤筒和第二洗涤筒的剩余加热时间相等。此时,需判断洗涤筒的剩余加热时间是否大于设定值Tmax;
若是,则依据交替加热原则,执行第一洗涤筒和第二洗涤筒交替加热的交替加热程序;
若否,则依据顺序原则,执行先第二洗涤筒后第一洗涤筒加热的顺序加热程序。
进一步,所述的交替加热程序为,第一洗涤筒和第二洗涤筒依次交替加热一定时间间隔,每个时间间隔加热结束后,判断第一洗涤筒和第二洗涤筒是否加热结束,若第一洗涤筒或第二洗涤筒加热结束,则第二洗涤筒或第一洗涤筒一直加热至结束,否则,继续交替加热。
本实施例中,所述的第二洗涤筒加热的全部时间为Tm2。所述的设定值Tmax满足如下条件,2/3Tm2≤Tmax≤Tm2;优选的,10min<Tmax。所述的设定值Tmin满足如下条件,0<Tmin≤1/3Tm2;优选的,0<Tmin≤5min。
进一步,所述的顺序加热程序为,先开始执行的洗涤筒优先执行,以避免程序打断后造成热损耗情况的发生。
因此,需让先开始执行的第二洗涤筒继续执行加热程序;后开始执行的第一洗涤筒暂缓执行,至第二洗涤筒执行完加热程序后,再执行加热程序。
特殊情况2、在第一洗涤筒需执行加热程序时,若第二洗涤筒正在执行加热程序,而第二洗涤筒的剩余加热时间较短(不大于设定值Tmin)。此时,由于等待时间较短,为了降低热损耗,则需先令第二洗涤筒执行完加热程序后,第一洗涤筒再开始执行加热程序。
因此,在上述步骤1)至11)的基础上需增加如下步骤:
在第一洗涤筒执行加热程序前,若第二洗涤筒正在执行加热程序;需判断第二洗涤筒的剩余加热时间是否小于最短设定值Tmin;
若是,第一洗涤筒暂缓执行加热程序;至第二洗涤筒执行完加热程序后,第一洗涤筒再执行加热程序;
若否,执行本实施例中的步骤2)。
实施例五
本实施例中介绍了一种多滚筒洗衣机的加热控制方法如下:
在第一洗涤筒执行加热程序前,需先对第二洗涤筒是否正在执行加热程序进行判断,以避免第一洗涤筒和第二洗涤筒同时执行加热程序,洗衣机产生较大负荷电流情况的发生。
本实施例中,指定第一洗涤筒正常情况下优先执行加热程序,令用户将急需洗涤的衣物投放至第一洗涤筒中,以缩短用户对急需洗涤衣物的等待时间。
而在第一洗涤筒所需加热时间过长的特殊情况下,令第二洗涤筒执行完正在执行的程序后,第一洗涤筒再开始优先执行加热程序,以避免第二洗涤筒等待时间过长情况的发生。
优选的,第一洗涤筒的洗涤容量小于第二洗涤筒的洗涤容量。
本实施例中,通过下述三个判断条件对第一洗涤筒所需加热时间是否过长进行判定:
11)第一洗涤筒的设定加热温度是否高于常用设定温度;
12)第一洗涤筒的设定水位是否大于常用水位;
13)第一洗涤筒的设定加热温度值与实际测量值之差是否大于第二洗涤筒的设定加热温度值与实际测量值之差;
若上述判断条件11)至判断条件13)中的任一为是,则第一洗涤筒所需加热时间过长;
若上述判断条件11)至判断条件13)均为否,则第一洗涤筒所需加热时间不过长。
如图3所示,本实施例中,多滚筒洗衣机的加热控制具体方法如下:
1)、第一洗涤筒执行加热程序前;
2)、判断第一洗涤筒的设定加热温度t1是否高于常用设定温度t′;若否,执行步骤3);若是,执行步骤5);
3)第一洗涤筒的设定水位Q1是否大于常用水位Q′;若是,执行步骤4);若否,执行步骤5);
4)第一洗涤筒的设定加热温度值t1与实际测量值t1n之差是否大于第二洗涤筒的设定加热温度值t2与实际测量值t2n之差;若否,执行步骤12);若是,执行步骤5);
5)判断第二洗涤筒是否正在执行加热程序;若是,执行步骤8);若否,执行步骤6);
6)判断第二洗涤筒是否正在执行脱水程序;若是,执行步骤9);若否,执行步骤7);
7)判断第二洗涤筒是否正在执行烘干程序;若是,执行步骤10);若否,执行步骤11);
8)第一洗涤筒暂缓执行加热程序,第二洗涤筒继续执行加热程序;至第二洗涤筒加热程序完成后,第一洗涤筒再执行加热程序;
9)第一洗涤筒暂缓执行加热程序,第二洗涤筒继续执行脱水程序;至第二洗涤筒脱水程序完成后,执行步骤7);
10)第一洗涤筒暂缓执行加热程序,第二洗涤筒继续执行烘干程序;至第二洗涤筒烘干程序完成后,执行步骤11);
11)第一洗涤筒执行加热程序;
12)判断第二洗涤筒是否正在执行加热程序;若是,执行步骤15);若否,执行步骤13);
13)判断第二洗涤筒是否正在执行脱水程序;若是,执行步骤15);若否,执行步 骤14);
14)判断第二洗涤筒是否正在执行烘干程序;若是,执行步骤15);若否,执行步骤16);
15)第二洗涤筒暂停执行对应程序,第一洗涤筒执行加热程序;至第一洗涤筒加热完成后,第二洗涤筒再恢复执行对应程序;
16)第一洗涤筒执行加热程序。
本实施例中,第一洗涤筒的设定加热温度t1、设定水位Q1是第一洗涤筒执行的洗涤程序所对应的设定值;第二洗涤筒的设定加热温度t2、设定水位Q2是第二洗涤筒执行的洗涤程序所对应的设定值。
本实施例中,常用设定温度t′和常用水位Q′为经过多次试验得出的洗衣机正常使用时,所需的加热温度和水位。优选的,第一洗涤筒设有多个进水水位,常用水位为调用次数较多的进水水位;第一洗涤筒还设有多个加热档位,各加热档位为调用次数较多的、较大加热档位所对应的设定温度值。进一步优选的,常用水位所对应的洗涤水深度值不大于第一洗涤筒直径的1/2、不小于第一洗涤筒直径的1/4。
例如:第一洗涤筒设有1、2、3、4四个进水水位,各进水水位自第1档至第4档依次增大;优选的,第一洗涤筒的常用水位Q′为3档进水水位。
第一洗涤筒设有5个加热档位,对应的设定加热温度分别为30、40、50、60和90摄氏度;优选的,第一洗涤筒的常用设定温度t′为60摄氏度。
本实施例中,第一洗涤筒的实际测量值t1n和第二洗涤筒的实际测量值t2n是对第一洗涤筒和第二洗涤筒中的洗涤水进行实时温度检测或定时温度检测得到的各对应次检测值。
从而,将第一洗涤筒指定为优先执行加热程序的优先筒,以便于用户将急需洗涤的衣物投放至该筒中洗涤,缩减用户的等待时间。同时,将第一洗涤筒相对第二洗涤筒的洗涤容量较小,以在正常情况下令小筒优先执行洗涤程序,进一步缩减用户对急需洗涤衣物的等待时间。更特别的是,在优先洗涤筒进行加热程序前,对所需加热时间进行预判,以对优先筒需要较长洗涤加热时间的特殊情况进行考虑,避免加热时间太长导致另一洗涤筒等待时间较长情况的发生,提高洗涤设备的人性化程度。
实施例六
本实施例与实施例四的区别在于:在执行实施例四中的步骤3)之前,先判断第一洗涤筒所需加热时间是否过长;若否,第二洗涤筒优先执行加热程序,至第二洗涤筒加热完成后,第一洗涤筒再执行加热程序;若是,则执行步骤3),依据剩余时间短优先执行的原则,确定第一洗涤筒的加热程序。
从而,令洗衣机的第一洗涤筒在正常情况下优先执行;而在第一洗涤筒的加热时间过长的特殊情况下,通过判断两个洗涤筒的剩余加热时间长短,使得剩余加热时间短的洗涤筒优先执行加热程序。
本实施例中,第一洗涤筒所需加热时间是否过长的判断方法与实施例五相同,通过下述三个判断条件对其进行判断:
11)第一洗涤筒的设定加热温度是否高于常用设定温度;
12)第一洗涤筒的设定水位是否大于常用水位;
13)第一洗涤筒的设定加热温度值与实际测量值之差是否大于第二洗涤筒的设定加热温度值与实际测量值之差;
若上述判断条件11)至判断条件13)中的任一为是,则第一洗涤筒所需加热时间过长;
若上述判断条件11)至判断条件13)均为否,则第一洗涤筒所需加热时间不过长。
实施例七
本实施例与上述实施例一至六的区别在于:第一洗涤筒执行加热程序、进水程序或补水程序前,最先执行如下判断:判断第二洗涤筒是否正在工作运行中;若否,第一洗涤筒直接执行对应的加热程序、进水程序或补水程序;若是,再执行实施例一至六任一中的步骤2),以确定第一洗涤筒是否执行对应的加热程序、进水程序或补水程序。
本实施例中,正在工作运行指正在执行进水程序、补水程序、洗涤程序、漂洗程序、排水程序、脱水程序、烘干程序等。
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。
