用户不用添加洗涤剂的洗涤方法及其洗农机 技术领域
本发明涉及的是一种洗衣机的洗涤环境， 具体地讲， 本发明涉及的是一种用 户不用添加洗涤剂并能够使洗净比满足最低标准的洗涤方法， 及其用于实现所述 方法的洗衣机。 背景技术
目前用户使用洗衣机都悬投入大量洗衣粉， 进行洗涤衣物。 但是衣物洗后会 残留一部分洗衣粉， 对人体皮肤具有刺激性， 并且洗涤液中含有不可降解分子， 对环境产生污染。
近些年来， 出现了将电解水用于洗涤或杀菌消毒的洗衣机， 在不添加洗涤液 的条件下进行洗涤， 为了提高洗涤效果， 一般是采取提高电解效率以得到 PH值较 高的强碱性水来加强洗涤效果， 其对衣物腐蚀性加大。
利用电解电离水、 调质液进行辅助洗涤甚至提出少用或不用洗涤剂的对比文 献如下：
CN99248529公开了一种带水电离装置的洗衣机， 水电离装置两侧连接有带阀 门的正电离子水出水管和负电离子水出水管， 其分别与洗衣筒连通， 其作用是减 少污染、 节约用水。
CN00110127公开了一种电化学洗衣机和电化学洗涤剂， 通过电泳和电解作用 使软化水质， 乳化、 分解油污， 漂除色渍， 杀菌消毒， 防止洗脱污物的再附着及 柔软或上浆的洗涤过程更加省时省费。 专用的电化学洗涤剂制造成本较低， 加量 较少， 对环境污染较小。
CN01139901公开了一种家庭用水净化系统及应用该系统的洗衣机， 采可使洗 涤水中所含的硬度成分、 有机物和污染物分离清除。
CN02106217公幵了一种电动洗衣机， 所述的洗衣机是用电解水进行洗涤的， 具体是， 向电解装置通电， 用气泵向电解槽输入空气使水流动， 提高水的电解电 解效率， 生成的电解水提高了洗涤性能。
CN99800057公开了一种洗涤方法和洗涤装置， 一边将含有碳酸离子和重碳酸 离子中至少一种离子以及碱金属离子的洗涤液软化， 一边洗涤被洗涤物。 软化前 的洗涤液可以用电解碳酸氢钠水溶液的方法获得， PH9. 5以上， 电导率 150ms/m以 上， 软化后的洗涤液总硬度处于 40ppm 以下， 但是， 该方案要求加入电介质， 并 且， 其所述的硬度的影响在本发明研究人员的试验中并非为必要指标。 专利号为 96243576. 7的中国专利文献中公开了一种电解装置， 主要由外壳、 过滤器、 电解槽、 交直流电源转换器、 控制按钮、 提式开关、 废水槽、 控制电路 等组成， 从该文献的说明书所公开的内容来看， 该电解装置主要用于直接与自来 水相连接、 又能摆脱自来水管、 带有蓄水池的两用连续式电解整水装置。
专利号为 99211396. 2 的中国专利中公开了一种能够杀灭衣物上病菌的洗衣 机。 它是在普通洗衣机外壳内部安装一个直流电解装置和直流稳压电源。 直流稳 压电源和洗衣机电源连接。 洗衣机工作时由直流稳压电源给直流电解装置提供直 流电流。 水从洗衣机入水管进入直流电解装置后， 水中的氯离子被电解， 在水中 生成可以杀死细菌的次氯酸 （H C 1 0 ), 进入洗衣机后把衣物上的病菌杀死。 本 产品效果很好， 结构简单， 成本低廉。
对于在给水的水路上进行电解的电解装置， 为了满足电解效率， 其还存在电 源板功率较大， 导致电源板发热的问题。
近些年来也有用电解水用于洗涤或用于杀菌消毒。 有的是将电解装置设在洗 涤外桶的内壁上， 例如中国专利 02106218. 8公开了一种电动洗衣机， 其是将电解 装置设在洗涤外桶内， 缺点是外桶在洗涤过程中随着水流的转动而摆动， 向外突 出的电解装置易于损坏。
从上述背景技术可以看出， 现有的电解水发生装置均设置在洗衣机外壳内的 外桶上， 随着消费者追求轻、 薄、 小、 功能强大等的消费理念的提出， 本发明设 计人在设计过程中发现， 如果在洗衣机的外桶与外壳之间容纳上述部件， 洗衣机 的内部可用空间越来越有限， 同时也为设计布局走线带来一定的困难， 如何能设 计出一种新型的即能充分利用洗衣机的各有用空间设计， 又能满足上述要求的洗 衣机， 是本发明设计人所要解决的关键问题。
并且对于现有的一设计出的双动力洗衣机， 如果想在此基础上增加电解水加 调质液的洗衣方案， · 则需要重新开机、 设计布线， 将电解装置和调质液供给装置 安装在洗衣机内部； 这样， 无疑会有费时、 费力、 制造成本高等方面的缺陷， 明 显不利于现有的洗衣机的改造。
所以， 本发明设计人在寻求解决第一技术问题时， 同时考虑如何能解决第二 技术问题， 设计一种既简单又方便的用户不用添加洗涤剂的洗衣机。
现有技术涉及的电解方式进行洗涤， 尤其是在所谓的不需要洗涤剂的状态下 洗涤， 通常存在着以下的缺陷： （1 ) 为了提高电解效率， 在洗涤用水中加入电介 质， 例如， 氯化钠等催化剂， 而这类电介质的加入， 虽然提高了电解效率， 但也 可能因为水质的变化尤其织物的板结； 同时使用洗衣机的用户需要人工添加， 当 用户不添加时效果差。 （2 ) 为了提高洗净比， 在洗涤用水中注入气泡， 显然， 这 种方式可能增加机构的复杂程度并导致成本的提升； （3 ) 部分文献提出使用二次 洗涤的方式， 实际上， 这种方式是增加洗涤时间。
此外， 在现有技术的对比文件中可以看出， 目前业内人士也没有对洗衣机的 洗涤最佳效果、 最佳洗涤环境提出研究的方向及目标， 所以， 本发明的设计人针 对上述现有技术的缺陷和不足， 从洗衣机的洗涤环境着手， 经历无数次的实验、 测试， 终于得出如何能获得洗衣机的洗涤环境、 最佳效果的洗涤方法。
有鉴于此， 提出克服上述缺陷的本发明。 发明内容

本发明的目的在于提供一种不用改变原有洗衣机的内部结构、 通过外挂一结 构简单、 安装方便的洗涤辅助装置， 将现有的洗衣机改装成一种用户不用添加洗 涤剂的洗衣机。
本发明的另一目的在于提供一种具有结构简单、 安装方便， 具有新型洗涤辅 助装置的用户不用添加洗涤剂的洗衣机。
本发明的研究人员认为， 硬度对去污的影响， 主要是由于它对洗涤溶液中洗 涤剂的化学结构、 洗涤剂分子与污渍分子之间的作用产生影响所造成， 而在本发 明中的洗涤环境下， 这种影响是几乎不存在的， 由此推断水的硬度不会对实际去 污有特殊的负面影响。 虽然本发明的研究人员认为在本发明的环境下， 硬度对洗 涤率不具有决定性的影响， 但是， 作为检测的结果， 本发明的洗涤环境中， 洗涤 液的硬度控制在 5— 400ppm之间， 该硬度是电解过程和调质剂的共同作用下得到 的。
为实现上述发明目的， 本发明采用的技术方案包括对自来水进行电解 （或同 时加入一定量的调质剂） ， 电解水的 PH值在 8. 5-11之间， 电解后 （包括可能加 入的调质剂）洗涤液的电导率在 261us/cm— 875us/cm之间，表面张力 25— 40 mN/m 之间。 该方法中采用的洗涤液是电解水 （或加入调质剂） 的混合液， 洗涤时的水 温在 5°C— 50°C之间， 最佳在 10°C— 30Ό之间。

当洗涤液的 PH值低于 8. 5时， 在电解水中加入适当的洗衣粉； 洗衣粉的加量不 超过洗搽用水量的 0. 2%。
正如对现有技术的分析那样， 洗涤环境是一个复杂的环境， 单一因素得改变 很难满足现代洗涤的要求， 因此， 无论作为一种选择性发明， 还是开创性发明， 本发明主要的贡献在于将多种因素控制在一个范围之内， 使得该范围内的洗涤液 对衣物进行洗涤时， 其综合指标始终能够在标准的范围内。

本发明的优选方案为： 将电解水发生装置中的电解槽 31 和 /或调质液添加装 置中的储液箱 41外挂在洗衣机外壳的后壁上， 其余部件仍可设置在洗衣机外桶与 外壳之间。 进一步具体的说， 只需在现有洗衣机的外壳壁上开有穿孔 111、 112： 进水管路 23通过上穿孔 111与电解槽 31、储液箱 41相连； 电解水排出管 24通过 下穿孔 112与洗涤桶进水管 25相连， （参见图 3、 图 4， 分别从洗衣机的后部、 侧 面反映）。 对于只采用电解水发生装置的洗衣机， 可以只将电解槽外挂在洗衣机外 壳壁上。 综合考虑外挂容器配件的大小、 重量等方面的原因， 所述的电解槽和 /或 储液箱的厚度小于洗衣机厚度的 1/4， 优选为 1/10, 其宽度和高度均小于洗衣机 的宽度和高度。
对挂接固定在洗衣机外壳后壁上的电解槽 31和 /或储液箱 41， 在其外部罩上 一盖板 5， 盖板 5通过螺钉 51螺接与外壳固定成一体。
在洗衣机内设置电解水发生装置和调质液添加装置， 通过在洗衣机的给水回 路上的进水口处设置一三通阀， 在排水、 排液口处设置排水、 排液阀或分别设置 排水阀、 排液阀。 本发明申请人在 2003年 11月提出的一系列申请中已有详细说 明， 如： 申请号为 200320121902. 8， 发明名称 "添加剂供给装置"、 申请号为 200320121903. 2, 发明名称 "一种电解水给水回路"、 申请号为 200320121901. 3， 发明名称 "一种具有电解装置的洗衣机" 以及申请号为 200310113629. 9， 发明名 称 "洗衣机以及洗涤方法"等， 这些文献的相关内容在此引入作为背景文献和技 术细节公开文献， 所以， 本说明书就不再进行详细说明。
在使用时， 其进水阀 3 的进口连接到自来水管， 其具有三个出口： 出水口分 别为直接连接于洗涤桶的主进水口、 与软化剂盒连接的进水口和与电解水发生装 置连接的电解进水口。 其控制部分的电脑板中有普通的洗涤程序， 也有使用电解 水、 不使用洗衣粉的程序。
当用户选择不用洗衣粉程序时， 电解水发生装置工作， 进水时自来水通过进 水阀 3 的电解阀口， 控制流量， 使流量在 1. 0〜10L/min 范围内， 最好在 3. 5〜 6. 0L/min范围内， 以保证电解的效果。 自来水进入电解槽 31， 在电解槽 31 中进 行电解， 通过正极、 负极电解为碱性和酸性水， 中间带有隔膜将其隔离分开， 碱 性水通过第一排水通道 34进入内桶， 进行洗涤衣物， 同时电解产生的酸水通过第 二排水通道 35排水管排出，可以进行杀菌消毒，由于本发明的电解槽的阴极室 311 和阳极室 312的流道横截面积的比值为 4 : 1，所以控制碱性水的流量大于酸性水的 流量， 实现碱性水和酸性水的输出比例， 碱性和酸性水的流量比为 3: 1〜6： 1， 以减少浪费， 同时还确保电解的效果， 达到合理的 PH值， 使其电解时产生的碱水 PH=9. 8 ± 1. 2
当本发明的电解水发生装置进行逆向电解时， 从而使阴极室流出酸性水， 此 时由于阴极室 311和阳极室 312的流道横截面积的比值的设定， 使从第二排出通 道 35排出的碱性水小于自第一排水通道 34引入到洗涤桶中的酸性水， 适用于漂 洗过程中， 具有消毒杀菌的功效。
在现有技术包括专利中， 已经提出了一些无需洗涤剂的洗衣机或者方法， 甚 至， 直接提出了用电解水进行洗涤的方式。
但是， 现有技术提出的基本是一种概念， 即， 利用电解， 使得洗涤用水的 PH 值提高， 高 PH值的洗涤用水能够提高洗净率也是一个现有技术的概念， 但是， 采 用什么水平的 PH值是合理的， 即平衡电解成本、 洗涤时间和不伤及物料却没有具 体的文献报道； 更为重要的是， 所谓的不用洗涤剂， 是在一个什么样的标准下进 行的， 因为， 如果抛开一个比较的标准， 这样的描述是没有意义的， 实际上， 在 没有比较标准的情形下， 单纯用水洗涤也能够达到一定的洗净比， 尤其在以灰份 为主要污垢的时候， 洗净比可以达到一个相当高的水平。
因此， 本发明首先引入比较的标准， 本发明将洗衣机的国家标准全部引入作 为本发明的内容的一部分， 具体地讲， 引入洗涤性能试验方法， 在该标准上， 详 细描述了洗涤性能的试验方法， 而支持本发明具有创造性所需要的全部参数正是 基于该标准得到的。
而本发明主要从一定的水温、 一定的容量、 相同的程序着手， 对采用不同的 洗涤水质是否添加洗衣粉等方面， 对洗涤的效果 （洗净率、 PH值、 电导率、 表面 张力等） 进行综合试验， 从而可探讨如何获得一最佳洗涤环境的洗涤方法。
表 1、 表 2详细列出了本发明的试验过程和试验条件， 具体参见表 1、 表 2。 表 1 设定水温 1(TC， 容量 100 %的情况下实验数据:
Figure imgf000012_0001
上述表 1中的比较试验的其他条件是:
( 1 ) 负载 5. 2Kg;
( 2 ) 洗涤程序采用标准程序； (3) 实验条件中数值为实际水温在： 9.2°C— 15.1°C之间的多次试验的范围 值；
(4) 试验机型为双动力洗衣机； （所述双动力洗衣机可参见 CN02110035、 CN02110368等， 本申请人的在先公开的双动力洗衣机的技术方案均被引入作为背 景）
从上表实验数据可以看出， 在相同设定温度、 相同设定体积的容量、 执行相 同洗涤程序等条件下， 采用改善水环境的电解水 （以下称活性电解水） 进行洗涤， 其平均洗净率为 0.265， 平均 PH值为 10.57, 平均表面张力为 32mN/m， 平均电导 率为 261.5 us/cm; 采用单纯电解水进行洗涤， 其平均洗净率为 0.16， 平均 PH值 为 10.6， 平均表面张力为 66mN/m， 平均电导率为 604.5 us/cm; 采用添加 0.2% 的洗衣粉的电解水进行洗涤， 其洗净率为 0.2768， PH值为 10.656， 表面张力为 30mN/m, 平均电导率为 283 us/cm; 采用自来水进行洗涤， 其平均洗净率为 0.108, 平均 PH值为 7.473， 平表面张力为 69mN/m， 平均电导率为 222 us/cm; 采用添加 0.2%的洗衣粉的自来水进行洗涤， 其平均洗净率为 0.2803， 平均 PH值为 7.473， 平均表面张力为 30mN/m, 平均电导率为 222 us/cm。
从上述的数据可以得出的结论是： 采用活性电解水、 单纯电解水还是添加洗 衣粉的电解水进行洗涤， 与单纯电解水还是自来水和添加洗衣粉的自来水进行比 较， 不使用洗衣粉时能获得的最佳洗涤环境： 其平均洗净率为 0.265， 平均 PH值 为 10.57， 平均表面张力为 32mN/m， 其平均电导率 261— 262us/cm。
表 2 设定水温 30Γ， 容量 80%的情况下实验数据：
Figure imgf000013_0001
上述表 2中的比较试验的其他条件是-
(1) 负载 5.0Kg;
(2) 洗涤程序采用标准程序；
(3) 实验条件中数值为实际水温在： 30°C— 32°C之间的多次试验的范围 值；
(4) 试验机型为双动力洗衣机；
从上表实验数据可以看出， 在相同设定温度、 相同设定体积的容量、 执行相 同洗涤程序等条件下， 采用电解水进行洗涤， 其平均洗净率为 0. 326， 平均 PH值 为 10. 19， 平均表面张力 31mN/m,平均电导率为 575. 5 us/cm; 采用添加 0. 2 %的 洗衣粉的电解水进行洗漆， 其洗净率为 0. 36， PH值为 10. 158， 表面张力 67mN/m， 平均电导率为 318 us/cm; 釆用自来水进行洗涤， 其平均洗净率为 0. 1949， 平均 PH值为 7. 547， 表面张力 70mN/m， 平均电导率为 203 us/cm; 采用添加 0. 2 %的洗 衣粉的自来水进行洗涤， 其平均洗净率为 0. 326， 平均 PH值为 7. 708, 表面张力 mN/m平均电导率为 214 us/cm。
不管采用电解水还是添加洗衣粉的电解水进行洗涤， 与自来水和添加洗衣粉 的自来水进行比较， 不使用洗衣粉时能获得的最佳洗涤环境： 其平均洗净率为 0. 326， 平均 PH值为 10. 19， 平均表面张力 31mN/m左右； 但是， 其平均电导率偏 高。
从上述数据可以看出， 使用电解水时， 加洗衣粉会增加洗涤水的洗涤效果； 使用电解水的 PH值比自来水的 PH值更接近洗衣机行业的标准值， 并且， 使用电 解水的洗涤水表面张力比使用自来水的表面张力要低很多， 其洗净效果好。
从上面两个表综合考虑， 可以看出， 不考虑容量的大小、 是否添加洗衣粉， 在洗涤环境一致的情况下， 30°C的水温环境比 10°C的水温环境更有利于进行洗漆， 获得较佳的洗涤效果。
