Description

超量氢气杀菌洗衣机 技术领域
本发明涉及一种洗衣机，属于洗衣机技术领域。
背景技术
洗衣机是用来洗衣服的家电产品。然而，对于女性(尤其是孕妇)和婴幼儿童的衣物，则不仅仅是把衣服表面的污垢洗净，还有着其它更高要求：
1)衣物的杀菌消毒尤为重要。女性和婴幼儿童的皮肤都比较娇嫩，对于一般的洗衣机来说，它的功能仅仅就是把衣服表面的污垢洗掉，但是对附着在衣服上的病毒细菌确无能为力，这样的衣服给健康埋下了隐患。
2)现有洗衣机都难以避免衣物洗涤后残留有不同程度的洗涤剂。尤其是表面活性剂，很难漂洗干净。女性和婴幼儿童穿着残留有洗涤剂的衣物，很容易引起皮肤过敏，甚至诱发皮肤病。
为减少洗涤剂对人体的伤害，以及洗衣污水对环境的危害，而开发了可少用乃至免用洗涤剂的各种洗涤技术，国内外已公示有相当多的相关技术专利。
迄今已面世的无洗衣粉洗衣机技术有：
1)有隔离膜电解技术
将水电解为弱碱性水(PH值为9－11之间，相当于洗衣粉融于水后的弱碱性水)，与衣物污垢发生皂化反应，并使洗衣水产生活性氧和氢氯酸。已上市无洗衣粉洗衣机典型产品：日本三洋(超声波+电解)、海尔(有隔膜电解+暗藏一罐高浓度表面活性剂)、格力(有隔膜加盐电解以提高碱性)；伊莱克斯(电解离子水)
2)超声波技术
3)臭氧技术，或臭氧+生物酶技术
3)置放洗衣球辅助揉搓技术
4)洗衣机内置电磁装置使水磁化技术
上述现有无洗衣粉洗衣机技术之不足是：
1)主要是针对受污并不严重的衣物，其平均洗净比一般只能达到0.6到0.7(国标下限为0.7)，洗涤力不强。
2)对于影响洗涤质量的重要因素——水的硬度，均无软化改善效果。
发明内容
本发明解决的技术问题是：提出一种可生成含有大量超微气泡和强氧化因子并具有极好还原性洗涤用水进行衣物洗涤的装置。
为了解决上述技术问题，本发明提出的技术方案是：一种超量氢气杀菌洗衣机，包括洗衣机筒体，所述洗衣机筒体内设置有一个以上的电解单元，所述电解单元包括阴电极和阳电极，成对阴电极和阳电极之间无间隙地夹持有透水性多孔膜，所述透水性多孔膜与所述阴电极或阳电极相对侧面的面积小于所述阴电极或阳电极与透水性多孔膜相对侧面的面积。
上述技术方案中所述透水性多孔膜也叫透水膜或透水性隔离膜，是指可以穿透水分子的隔膜，其透水孔径从毫米级到纳米级，包括日常水处理使用的各种过滤膜，如：超滤膜(UF)、纳滤膜(NF)和微滤膜(MF)，等。
上述本发明技术方案的改进是：所述透水性多孔膜的透水孔径小于等于2毫米且大于等于1纳米。
上述本发明技术方案进一步的改进是：所述阴电极和阳电极之一的表面开孔。
上述本发明技术方案再进一步的改进是：所述透水性多孔膜与所述阴电极和阳电极中的最小面积之比是4：5～3：5。
上述本发明技术方案更进一步的改进是：所述透水性多孔膜是双层叠压。
上述本发明技术方案进一步的完善是：所述阴、阳电极采用恒功率交变脉冲电源进行供电。
上述本发明技术方案再进一步的完善是：所述阳电极是一大块圆板钛基覆涂铂族氧化物制成的惰性电极，所述阴电极是彼此并联的八个小块圆板钛基覆涂铂族氧化物制成的惰性电极，所述透水性多孔膜采用的是平均疏水孔径为0.01～0.05微米的圆形平面超滤膜片。
上述本发明技术方案更进一步的完善是：所述电解单元沿洗衣机筒体的内侧面均匀布置。
本发明的超量氢气杀菌洗衣机的有益效果是：
1、水中形成有大量以氢气为主的超微气泡；
2、具有极好的还原性，其氧化还原电位为负值；
3、当电解阳极材质为非碳材料时，水中还含有相当数量的强氧化因子，如双氧水(H2O2)、臭氧O3、羟基自由基·OH等，宏观表现出具有一定的杀菌消毒能力。
上述有益效果的原因机理说明参见后面具体实施方式中的有关制取机理分析。
附图说明
下面结合附图对本发明的超量氢气杀菌洗衣机作进一步说明。
图1是本发明实施例超量氢气杀菌洗衣机的内部局部结构示意图。
图2是图1的左视图。
具体实施方式
实施例一
本实施例的超量氢气杀菌洗衣机参见图1，包括洗衣机筒体10，洗衣机筒体10内设置有八个的电解单元20，电解单元20沿洗衣机筒体10内的波轮11周圈均匀布置。
如图2所示，电解单元20包括阴电极2、阳电极3，阴电极2和阳电极3之间无间隙地夹持有透水性多孔膜4，透水性多孔膜4与阴电极2或阳电极3相对侧面的面积小于阴电极2或阳电极3与透水性多孔膜4相对侧面的面积。透水性多孔膜4的透水孔径小于等于2毫米且大于等于1纳米。
本实施例阳电极3为一大块圆板钛基覆涂铂族氧化物制成的惰性电极，阴电极2是8个小块圆板钛基覆涂铂族氧化物制成的惰性电极彼此并联。透水性多孔膜4采用的是平均疏水孔径为0.02微米的圆形平面超滤膜片，极限耐热温度180℃，采用双片叠加，支撑面在外；疏水多孔膜4与阳电极3的面积比为4:5(也可以是3:5)
本实施例的阴电极2和阳电极3采用恒功率交变脉冲电源进行供电。
本实施例阴电极2和阳电极3可以想到的变化是：1)一大块圆板的阳电极3也可以采用与阴电极2相似结构，即变成8个小块圆板彼此并联；2)阴电极2除了8个小块圆板以外也可以是其他数量，如2个、4个、6个等。
本实施例的洗衣机中，分别在广西玉林市、深圳市、上海市、山东淄博市、北京市，以当地市供自来水进行了考核实验，结果如下：
1、参照GBT 4288-2003家用电动洗衣机附录A洗涤性能试验方法，分别以墨汁、牛奶、咖啡、果汁、红葡萄酒、食用橄榄油为污染液，制取样布，然后以另一台未改造的市售小鸭XPB30-B型MINI洗衣机为对比参照机，在相同的洗涤条件下进行了洗涤效果的定性比对试验。
1)在不另加洗衣粉的情况下，本发明实施例样机的洗净度明显好于参比机；
2)本发明实施例样机不加洗衣粉，参比机加洗衣粉，两者的洗净度相当；
3)本发明实施例样机加入少量小苏打粉(约20克)，参比机加洗衣粉，则本发明实施例样机洗净度优于参比机。
2、将深圳、上海、淄博、北京所住旅店的浴巾和毛巾丢入本发明实施例样机，只以当地市供自来水源水(无任何添加剂)，洗涤5分钟后，洗衣机中的水均表现为黏黏滑滑且泛出大量泡沫，且闻到刺鼻漂白粉味道，说明其洗涤剂残留十分严重。
3、将广西梅雨季节所收藏发霉衣物尤其是毛绒织物投入本发明实施例样机漂洗处理后，霉斑彻底去除。用干衣机风干后再入柜放置，至下一梅雨集取出观察，凡经本发明实施例样机漂洗处理的，均无再发霉现象。而用常规洗衣机洗净，同样用干衣机风干后再入柜放置的又出现有发霉乃至霉斑现象。
4、本发明实施例样机已历经一年多的连续使用考核，一直工作正常，原来担心的疏水膜长期处在重度污染下会否失效、阻塞、乃至短路，实际并未发生，说明其性能是稳定可靠的。
5、实验还发现，同样是添加洗涤剂的情况下，本发明实施例样机所排废水中的阴离子表面活性剂(LAS)含量要比参比洗衣机的LAS残留量少。
6、经本发明实施例样机洗涤的衣物还有一个特点，就是脱色现象大大减轻，所洗衣物的蓬松度较之用普通洗衣机加洗衣粉洗后结板情况形成鲜明对比。
分析认为，本发明实施例样机洗涤的衣物之所以有如此好的效果，乃是由于：
1)本发明实施例样机在电解时生成大量H2泡，而氢气泡较之臭氧或超声波机械方法产生的气泡要小得多。这些超微气泡穿过衣物上升过程中不断破裂产生振动，加之洗衣机波轮的搅动作用，使污垢更好的溶入水被水带走；
2)本发明实施例样机在电解时可能生成的各种强氧化因子，例如臭氧、羟基自由基(·OH)、次氯酸HCIO、双氧水H2O2等，起到了对衣物去污漂白、消毒杀菌作用，对有机污染物有着很强的氧化性。加入碘化钾还原指示剂可明显看出，经本发明实施例样机处理后的水是亮黄色，而未经电解的自来水没有颜色的变化，可知处理后的水中有氧化物的生成。
3)本发明实施例样机处理后的水具有极强的还原性，且水的缔合度下降，分子团变小，溶解力、渗透力增强，起到湿润、乳化、分散、增溶作用，也就是表面活性剂的作用，使污垢被洗掉。为了解本发明实施例装置所处理水的渗透力与溶解力的增强，采用了简单的爬粉笔实验与未经处理的自来水原水作了比较：两个分别装有等量所处理水和自来水的烧杯中，分别插入两只粉笔，在相同的时间(10分钟)内观察两只粉笔浸水的高度，实验结果如下表：

Figure PCTCN2015076243-appb-000002
本发明的超量氢气杀菌洗衣机不局限于上述实施例所述的具体技术方案，比如：1)阴电极2、阳电极3也可以是二对或更多对；2)透水性多孔膜4也可以是单层或多层超滤膜片叠加而成；3)超滤膜片的形状也可以是方形；4)电解单元20数量也可以是2个、4个、6个、12个或其他数量，等等。凡采用等同替换形成的技术方案均为本发明要求的保护范围。
