Description

一种絮凝洗衣机的控制方法及洗衣机 技术领域
本发明涉及洗衣机领域，具体是循环节水洗衣机，尤其是一种絮凝洗衣机的控制方法及洗衣机。
背景技术
随着人们生活水平的提高，洗衣机现已成为人们日常生活的主要家电之一，洗衣机的洗衣过程主要包括洗涤、漂洗、甩干几个阶段，在洗涤阶段洗衣机进水和洗涤剂对衣物进行洗涤，进入漂洗阶段后为了漂净污渍和残留的洗涤剂，需要进更多的水或执行更多的漂洗次数对衣物进行漂洗，这势必耗费大量的水资源，即使是省水的滚筒洗衣机，为了漂净衣物也需要漂洗至少两次，这一过程至少要消耗30L以上的自来水。有时衣物上的污渍较少或投放的洗涤剂较少，可能两次就漂洗干净了，但由于用户选择了3次漂洗，势必也会造成水资源的浪费，比如6Kg的全自动洗衣机一般两次漂洗水基本用水量在100升左右。如何在洗净衣服的同时能够做到省水省电，一直是消费者关注的焦点之一。
目前为止尚未有家用洗衣机配套使用的水净化及循环利用装置，即便是所谓的带有节水功能的洗衣机，一般在洗衣机的侧位安装储水箱，采用水泵进行注水和排水，一般能够一次注水，漂洗3次，起到节水功能。但洗涤后的水不能够保存，同时使洗衣机本身结构复杂、庞大，不利于运输、回收处理等。由于体积、结构以及灵活性等方面的限制，影响了洗衣机原有功能以及节水箱本身功能的充分发挥。在现有洗衣方式的基础上为了更好的节约水资源，很多厂家投入了大量的研发。
现有洗衣机带有循环水功能，其仅仅起到过滤线屑，洗涤均匀或者添加加臭氧、重金属离子杀菌等作用。无法改善耗水量，且对洗净没有根本的提高。
洗衣水的循环利用，经查阅相关专利文献，如申请号为200810072420.5的“洗衣机循环用水节水装置”，是将洗衣水输入一个水筒内，进行净化处理。该发明对于第一遍的洗衣水不进行净化直接排掉，对于第二、第三遍的漂洗用水进行净化处理之后，要留待下次洗衣时使用。
还有一种常用的污水处理方法为絮凝处理方法，其采用絮凝剂对污水中所包含的污物进行絮凝处理，使污水中的污物变为絮凝物与水分离开。采用此种污水处理方式，高效、环保、节能、成本低廉。因此，将絮凝处理污水与洗衣机相结合，生成新的循环水洗衣机的方式成为了创新热点。
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，提供一种絮凝洗衣机的控制方法，以实现对絮凝程序的精确控制。

4)依据洗涤水的絮凝循环次数N＝基础絮凝循环次数N1+变量絮凝循环次数N2，得出洗涤水的絮凝循环次数N。
进一步，洗衣机的具体步骤如下，

进一步，洗衣机完成絮凝循环次数N后，对絮凝自清洁完成后的洗涤水进行浊度检测得出洗涤水浊度值P，当洗涤水浊度值P≥漂洗设定值Pmin时，盛水筒中的洗涤水排至洗衣机外，洗衣机由外部正常进水做为漂洗水，对衣物进行漂洗；当洗涤水浊度值P＜漂洗设定值Pmin时,洗衣机利用盛水筒中的洗涤水做为漂洗水，对衣物进行漂洗；
优选的，在洗衣机每次完成絮凝循环处理后，均对盛水筒中的洗涤水进行浊度检测得出洗涤水浊度值P，当洗涤水浊度值P≥漂洗设定值Pmin时，盛水筒中的洗涤水排至洗衣机外，洗衣机由外部正常进水做为漂洗水，对衣物进行漂洗；当洗涤水浊度值P＜漂洗设定值Pmin时,洗衣机利用盛水筒中的洗涤水做为漂洗水，对衣物进行漂洗；
进一步优选的，在洗衣机每次完成絮凝循环处理后，均对回流入盛水筒中的、絮凝处理后的洁净水进行浊度检测得出洁净水浊度值P1，当洁净水浊度值P1≥漂洗设定值Pmin时，盛水筒中的洗涤水排至洗衣机外，洗衣机由外部正常进水做为漂洗水，对衣物进行漂洗；当洁净水浊度值P1＜漂洗设定值Pmin时,洗衣机利用盛水筒中的洗涤水做为漂洗水，对衣物进行漂洗。

实施例一
如图1所示，本实施例中，洗衣机设有不同进水量L分别为L1、L2...Ln，对应不同的絮凝循环次数N，代表洗涤水的絮凝循环自清洁处理次数；对应的N分别为N1、N2...Nn。
不同进水量L分别为L1、L2...Ln，对应不同的絮凝剂的添加量A，代表洗涤水絮凝循环自清洁过程中需添加的絮凝剂总量；对应的A分别为A1、A2...An。优选的，在进水量为Ln、需添加的絮凝剂总量为An情况下，第一次絮凝循环至第N次絮凝循环的絮凝剂添加量分别为An1、An2...Anm；上述各Anm中的n与对应进水量Ln中的n相同，所述的m＝絮凝循环次数N；且An1＞A2n＞...＞Anm，An1+An2+...+Anm＝对应絮凝剂总量An。通过将第一次絮凝循环至第N次絮凝循环，每次絮凝循环中絮凝剂的投放量递减设置，使得前期洗涤水较脏时投入大部分絮凝剂，以降低絮凝处理时间、提高絮凝处理效率。
进一步优选的，An1＝t％An、A2m＝t％(An-An1)...An(m-1)＝t％(An-An1-...-An(m-2))、Anm＝An-An1-...-An(m-2)-An(m-1)；所述的100＞t＞0。
不同进水量L分别为L1、L2...Ln，对应不同的絮凝单次进水量V，代表每次絮凝循环处理过程中流入絮凝容器中洗涤水的设定容量；对应的V分别为V1、V2...Vn。
上述的n为大于1的整数。上述的N1、N2...Nn和A1、A2...An和V1、V2...Vn和各Anm均为预存在洗衣机上的设定值，供洗衣机洗涤时调用。
例如，洗衣机设有三个进水水位分别对应进水量L为，三个水位对应的进水量分别为L1＝14升、L2＝30升、L3＝50升；对应的每次絮凝循环处理过程中流入絮凝容器中洗涤水的设定容积V分别为V1＝10升、V2＝20升、V3＝20升；对应的絮凝剂的添加量A分别为A1＝4g、A2＝7.3g、A3＝12g；对应的絮凝循环次数N分别为N1＝3、N2＝6、N3＝9。

实施例二
如图2和图4所示，本实施例与实施例一存在如下区别：所述絮凝循环次数N的具体确定步骤如下，
1)根据洗涤衣物的重量和/或材质来确定,或由用户直接设定，或经盛水筒上设置的第一液位传感器检测得出洗涤水的对应进水量L，通过第一液位传感器使注入盛水筒中的自来水为对应进水量L；
2)依据对应进水量L，调用对应洗涤水的基础絮凝循环次数N1和对应洗涤水浊度的判定值P′；
3)盛水筒中的第一浊度传感器检测得到洗涤完成后洗涤水的浊度值P,将检测值P与对应洗涤水浊度的判定值P′比较，若P≥判定值P′时，变量絮凝循环次数N2＝1；若P＜判定值P′时,变量絮凝循环次数N2＝0；
4)依据洗涤水的絮凝循环次数N＝基础絮凝循环次数N1+变量絮凝循环次数N2，得出洗涤水的絮凝循环次数N。
本发明中，洗衣机设有不同进水量L分别为L1、L2...Ln，对应不同的基础絮凝循环次数N1、洗涤水浊度的判定值P′和每次絮凝循环处理过程中流入絮凝容器中洗涤水的设定容积V，对应的N1分别为N11、N12...N1n；对应的P′分别为P1′、P2′...Pn′；对应的V分别为V1、V2...Vn。所述洗衣机的水位量为L1时，对应的基础絮凝循环次数为N11，对应的洗涤水浊度的设定值为P1′，对应的设定容积为V1；所述洗衣机的水位量为L2时，对应的基础絮凝循环次数为N12，对应的洗涤水浊度的判定值为P2′，对应的设定容积为V2...所述洗衣机的水位量为Ln时，对应的基础絮凝循环次数为N1n，对应的洗涤水浊度的设定值为Pn′，对应的设定容积为Vn。上述的n为大于1的整数。上述的N11、N12...N1n和P1′、P2′...Pn′和V1、V2...Vn均为预存在洗衣机上的设定值，供洗衣机洗涤时调用。
例如，洗衣机设有三个进水水位分别对应进水量L为，三个水位对应的进水量分别为L1＝14升、L2＝30升、L3＝50升；对应的每次絮凝循环处理过程中流入絮凝容器中洗涤水的设定容积V分别为V1＝10升、V2＝20升、V3＝20升；对应的洗涤水浊度的判定值P′分别为P1′＝500NTU、P2′＝500NTU、P3′＝500NTU；对应的基础絮凝循环次数N1分别为N11＝3、N12＝6、N13＝9；
即，1)洗衣机通过衣物重量检测程序得出洗涤水进水量L＝L1＝14升，通过第一液位传感器检测，保证实际进入的洗涤水水量为14升；
2)调用对应洗涤水的基础絮凝循环次数N11＝3和对应洗涤水浊度的判定值P1′＝500NTU；
3)盛水筒中的第一浊度传感器检测得到洗涤完成后洗涤水的浊度值P,将检测值P与500NTU比较，若P≥500NTU时，变量絮凝循环次数N2＝1；若P＜500NTU时,变量絮凝循环次数N2＝0；
4)依据洗涤水的絮凝循环次数N＝基础絮凝循环次数N1+变量絮凝循环次数N2，得出洗涤水的絮凝循环次数N；即当P＜500NTU时，絮凝循环次数N＝3+0＝3；当P≥500NTU时，絮凝循环次数N＝3+1＝4。
实施例三
本实施与实施例二存在如下区别：所述的洗衣机设有不同进水量L分别为L1、L2...Ln，对应不同的絮凝单次进水量V，分别为V1、V2...Vn；每个不同的絮凝单次进水量V对应不同的、絮凝过程中絮凝剂总添加量A，分别为A1、A2...An。
如图3所示，本实施例中，依据实施例一或实施例二中的方式得出絮凝循环次数N；
同时，依据进水量L得出对应的絮凝单次进水量Vn，依据絮凝单次进水量Vn得出对应的絮凝过程中絮凝剂总添加量An；
再依据絮凝循环次数N和絮凝剂总添加量An得出第一次絮凝循环至第N次絮凝循环的絮凝剂添加量分别为An1、An2...Anm。
上述各Anm中的n与对应絮凝单次进水量Vn中的n相同，所述的m＝絮凝循环次数N；且An1＞An2＞...＞Anm，An1+An2+...+Anm＝对应絮凝剂总量An。通过将第一次絮凝循环至第N次絮凝循环，每次絮凝循环中絮凝剂的投放量递减设置，使得前期洗涤水较脏时投入大部分絮凝剂，以降低絮凝处理时间、提高絮凝处理效率。
进一步优选的，A1m＝t％An、A2m＝t％(An-An1)...An(m-1)＝t％(An-An1-...-An(m-2))、Anm＝An-An1-...-An(m-2)-An(m-1)；所述的100＞t＞0。
上述的n为大于1的整数。上述的N1、N2...Nn和V1、V2...Vn和各Anm均为预存在洗衣机上的设定值，供洗衣机洗涤时调用。
实施例四
如图5所示，本实施例中，在洗衣机的洗涤程序完成后，盛水筒上设置的第一浊度传感器对盛水筒中的洗涤水进行浊度检测以得出洗涤水浊度值P。上述检测得到的洗涤水浊度值P与最大浊度值Pmax进行比较。
当洗涤水浊度值P＜最高设定值Pmax时,洗衣机按步骤11)至步骤16)对洗涤水进行絮凝处理，絮凝处理后的洁净洗涤水做为漂洗水，对衣物进行漂洗。
当洗涤水浊度值P≥最高设定值Pmax时，洗衣机按照正常漂洗程序执行：盛水筒中的洗涤水全部外排至洗衣机外，洗衣机由外部正常进水做为漂洗水，对衣物进行漂洗。
所述的最大浊度值Pmax为预存在洗衣机中的最大浊度值，以避免洗涤水太脏、絮凝程序处理后洗涤水的洁净度不达标情况的发生，达到缩减洗涤时间、提高洗衣机洗涤效率的目的。
实施例五
如图5所示，本实施例中，在洗衣机的絮凝程序完成后，盛水筒上设置的第一浊度传感器对盛水筒中的洗涤水进行浊度检测以得出絮凝自清洁完成后的洗涤水浊度值P。上述检测得到的洗涤水浊度值P与漂洗设定值Pmin进行比较。
当洗涤水浊度值P＜漂洗设定值Pmin时,洗衣机利用盛水筒中絮凝处理后的洁净洗涤水做为漂洗水，对衣物进行漂洗。
当洗涤水浊度值P≥漂洗设定值Pmin时，洗衣机再按照正常漂洗程序执行：盛水筒中的洗涤水全部外排至洗衣机外，洗衣机由外部正常进水做为漂洗水，对衣物进行漂洗。
所述的漂洗设定值Pmin为预存在洗衣机中的漂洗设定浊度值，以避免絮凝处理 后的洗涤水太脏、对衣物二次污染现象的发生，达到提高衣物漂洗洁净度的目的。
实施例六
如图6所示，本实施例中，洗衣机控制方法的具体步骤如下：
21)根据洗涤衣物的重量和/或材质来确定,或由用户直接设定，或经盛水筒上设置的第一液位传感器检测得出洗涤水的对应进水量L，调用与进水量L相对应的浊度判定值P′、基础絮凝循环次数N1、每次絮凝循环处理中絮凝剂的添加量Anm和絮凝单次进水量V；通过第一液位传感器使注入盛水筒中的自来水为对应进水量L，开始洗涤程序；
22)洗衣机洗涤完成后，利用第一浊度传感器对盛水筒中的洗涤水进行浊度检测得出洗涤水浊度值P；
23)将洗涤水浊度值P与最高设定值Pmax进行比较；若P≥Pmax时，洗衣机进入正常漂洗程序，洗涤水全部外排，自外部重新进自来水做为漂洗水，对衣物进行漂洗，漂洗结束排水，甩干，洗衣结束；若P＜Pmax时，执行步骤23)；
24)将P′与步骤23)得到的洗涤水浊度值P进行比较；若P≥判定值P′时，变量絮凝循环次数N2＝1；若P＜判定值P′时,变量絮凝循环次数N2＝0；
25)依据洗涤水的絮凝循环次数N＝基础絮凝循环次数N1+变量絮凝循环次数N2，得出洗涤水的絮凝循环次数N；
26)洗衣机开始絮凝程序，
27)盛水筒中的洗涤水经第一排水泵流入絮凝容器中，当第二液位传感器检测到絮凝容器中洗涤水的水位高度达到设定值，即流入絮凝容器中的洗涤水达到设定容积V时，第一排水泵停止工作；
28)絮凝剂投放器向絮凝容器中投放对应量Anm的絮凝剂；
29)洗涤水与絮凝剂充分反应，洗涤水中的污物在絮凝剂作用下，变为絮凝物，而洗涤水变为洁净水；
210)絮凝物漂浮至洁净水上表面；
211)利用第二浊度传感器检测絮凝容器中絮凝处理后的洁净水的浊度值P1；将P1与漂洗设定值Pmin进行比较；若P1≥漂洗设定值Pmin，絮凝处理后的洁净水不达标，洗衣机进入正常漂洗程序，洗涤水全部外排，自外部重新进自来水做为漂洗水，对衣物进行漂洗，漂洗结束后依次执行排水和/或甩干程序至洗衣结束；若P1＜漂洗设定值Pmin，絮凝处理后的洁净水达标，执行步骤212)；
212)絮凝自清洁处理后的洁净水回流入盛水筒中；
213)絮凝次数累加一次，并判断累加后的絮凝次数是否达到N；若未达到，执行步骤27)；若达到，执行步骤214)；
214)絮凝程序结束，洗衣机开始利用絮凝处理过后的水对衣物进行漂洗，漂洗结束后依次执行排水和/或甩干程序至洗衣结束。
通过对每次絮凝完成后的洗涤水进行浊度判断，避免絮凝处理后的洗涤水洁净度不达标，导致衣物二次污染现象的发生；同时，也提高了絮凝处理效率，避免絮凝程序完成后，再检测洗涤水依然不达标，导致的絮凝剂等资源浪费现象的发生。
实施例七
本实施例与实施例六存在如下区别：盛水筒中的第一浊度传感器检测得到洗涤完成后洗涤水的浊度值P,将检测值P与对应洗涤水浊度的判定值P′比较，若P≥判定值P′时，变量絮凝循环次数N2＝m1；若P＜判定值P′时,变量絮凝循环次数N2＝m2。所述的m1为大于0的正整数和m2为大于等于0的整数，且最大絮凝循环次 数＞m1≥m2≥0。优选的，所述的m2＝0，依据不同的进水量L对应不同的m1值，各m1均为最大絮凝循环次数＞m1＞0的整数。
实施例八
本实施例与实施例六存在如下区别：所述的不同进水量L所对应的判定值P′各为一组判定值；即，不同进水量L分别为L1、L2...Ln，对应不同值的洗涤水浊度的判定组P′，每组分别为P1′、P2′...Pn′；各组判定值P′分别包含至少两个大小不等的判定值，分别为Pn1′、Pn2′...Pnm′。上述的n与m均为大于1的任一整数，上述的各判定值P′均小于最大浊度值Pmax。
变量絮凝循环次数N2的确定步骤如下：
31)依据洗衣机的洗涤水进水量L，调用对应的判定组Pn′，其包含由大到小依次排列的多个判定值Pn1′、Pn2′...Pnm′；
32)检测洗涤水的浊度值P,并使N2初始化为0；
33)将洗涤水浊度值P与Pn1′比较，若P≥Pn1′，N2累加一；若P＜Pn1′输出N2；
将洗涤水浊度值P与Pn2′比较，若P≥Pn2′，N2再累加一；若P＜Pn2′输出N2...
将洗涤水浊度值P与Pnm′比较，若P≥Pnm′，N2再累加一，并输出N2；若P＜Pnm′输出N2。
通过为不同进水量对应由多个判定值P′组成判定组，实现了不同浊度洗涤水对应不同絮凝循环次数，以提高洗涤水絮凝处理精确度的目的。
实施例九
如图7所示，本实施例中，所述的絮凝容器11的下部与气泵8相连接.所述的气泵8向絮凝容器11中吹入气流，搅动絮凝容器11中的洗涤水旋转，加快絮凝溶剂的溶解速度，达到提高洗涤水与絮凝溶剂反应速度的目的。
实施例十
如图8所示，本实施例中，所述的絮凝容器11外部设有循环泵16，循环泵16的入口端与絮凝容器11的下部相连，循环泵16的出口端与絮凝容器11的上部相连，以使絮凝容器11中的洗涤水形成至絮凝容器11的下部至循环泵16至絮凝容器11的上部的循环水流，加快了絮凝溶剂与洗涤水的溶解速度，达到提高洗涤水与絮凝溶剂反应速度的目的。
实施例十一
如图9所示，本实施例中，所述的循环水处理装置还包括过滤装置17，所述的过滤装置17包括过滤容器171和设于过滤容器内的过滤网172。所述的过滤网172将过滤容器171内部分割为两部分，第一部分通过连接管与絮凝容器11连通，第二部分经设有第二排水泵的管路与盛水筒2连通。
所述的过滤装置17分别与絮凝容器11和盛水筒2相连通，将絮凝容器11内絮凝处理后的水进行过滤，再重新回流入盛水筒2内供洗衣机漂洗时再次使用。通过加设过滤装置，避免了絮凝物随洗涤水回流入盛水筒中情况的发生，避免了衣物被絮凝物二次污染现象的发生。
实施例十二
如图7至图9所示，本实施例中，所述的絮凝容器11中设有第二液位传感器9，以检测絮凝容器11中水的水位高度。
洗衣机开始絮凝程序后，开启第一排水泵5，盛水筒2中的洗涤水流入絮凝容器 11中，当第二液位传感器9检测到流入的洗涤水达到设定水位，即容积为设定值V的洗涤水流入絮凝容器11后，第一排水泵5关闭。
絮凝剂投放器13向絮凝容器中投放设定量的絮凝溶剂，以对流入絮凝容器中的设定水量V的洗涤水进行絮凝处理，使洗涤水中的污物变为絮凝物漂浮至絮凝处理后的洁净水上表面。絮凝处理完成后，洁净水自絮凝容器下部的回水口回流入盛水筒2中。
在絮凝容器中的洁净水回流过程中，第二液位传感器9对洁净水的水位高度进行实时测量，当洁净水的水位高度达到最低值时，第二排水泵6停止工作，絮凝容器11中的洁净水不再向盛水筒2中回流，以避免漂浮在絮凝容器中洁净水上表面的絮凝物回流入盛水筒中情况的发生。从而，避免絮凝物随洁净水回流，导致衣物二次污染现象的发生。
本实施例中，优选的，所述的絮凝容器11中设有第二浊度传感器10，用于检测絮凝处理后获得的洁净水的浊度。当洁净水的浊度达到漂洗设定值Pmin时，才打开第二排水泵6，使洁净水回流；未达到设定值Pmin时，打开排污阀7和第一排水泵5，使盛水筒2中的洗涤水全部经絮凝容器11排至洗衣机外部。从而，避免了絮凝处理不达标的洁净水对衣物造成的二次污染。
实施例十三
本实施例中，所述的循环水处理装置还包括工作结束将水排出到洗衣机外部的排水结构。
如图7至如图8所示，本实施例中，所述的排水结构为，与絮凝容器11相连通的排水管和设于排水管上的、控制排水管通断的排污阀7。所述的排水管一端与絮凝容器11的底部相连通，另一端设于洗衣机外部，以将洗衣机中的洗涤水、絮凝物等排至洗衣机外部。
如图9所示，本实施例中，所述的排水结构还可以设为，与过滤装置17相连通的排水管和设于排水管上的、控制排水管通断的排污阀7。所述的排水管一端与过滤装置17的底部相连通，另一端设于洗衣机外部，以将洗衣机中的洗涤水、絮凝物等排至洗衣机外部。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
