Description

过滤装置、 洗衣机和洗衣控制方法 技术领域
本发明涉及洗衣技术,特别是涉及一种过滤装置、洗衣机和洗衣控制方 法。 背景技术
传统的洗衣机不管波轮式还是滚筒式,半自动还是全自动洗衣机, 其洗 涤废水都直接排放, 同时使用大量清水进行多次漂洗, 耗水量比较大, 对水 资源的使用是一种极大地浪费, 对此, 现有技术中采取以下几种解决方式:
1. 增加储水箱, 将漂洗水收集, 滤网简单过滤再应用于下次洗涤, 这 种方式只是简单去除了线屑和添加水箱储存漂洗水, 出水杂质多, 水质不稳 定, 虽然能够对漂洗水进行净化以循环利用,但是未能从根本上解决漂洗水 水质问题, 且增加了洗衣机结构成本, 占用较大布局空间。
2. 使用反渗透过滤器对废水进行净化使用, 这种方式需要使用高压泵, 净化产水速率慢, 水量无法保证洗衣机的使用需求, 同时成本高。
3. 使用大型水处理装置、 臭氧发生器、 电解等附属设备对洗衣水进行 净化利用, 这种方式占用较大的布局空间, 且水处理成本较高。
4. 波轮机采用线屑收集滤袋, 人工清理线屑; 滚筒机采用排水泵泵头 截留大线头, 洗衣水排放。 这种方式过滤效果较差, 基本不截留线屑。
因此, 如何在优化洗衣机布局结构的同时还能提升漂洗水净化效率,是 本领域技术人员一直以来考虑的问题。 发明内容
在下文中给出关于本发明的简要概述,以便提供关于本发明的某些方面 的基本理解。应当理解, 这个概述并不是关于本发明的穷举性概述。它并不 是意图确定本发明的关键或重要部分,也不是意图限定本发明的范围。其目 的仅仅是以简化的形式给出某些概念,以此作为稍后论述的更详细描述的前 序。
本发明提供一种过滤装置、洗衣机和洗衣控制方法,在优化洗衣机布局 结构的同时还能提升漂洗水净化效率。 一方面, 本发明提供了一种过滤装置, 包括: 一体设置的粗过滤组件以 及超滤膜组件。

另一方面, 本发明提供了一种洗衣控制方法, 包括: 通过一体设置的粗 过滤组件和超滤膜组件循环过滤洗涤筒的排出水,其中洗涤筒的排出水依次 经过粗过滤组件和超滤膜组件处理后回流至洗涤筒。
本发明提供的技术方案中, 粗过滤组件可用于过滤线屑以及较大颗粒, 而超滤膜组件可用于过滤较小颗粒、可溶性污垢等。利用一体化设置的粗过 滤组件和超滤膜组件对漂洗水进行循环过滤, 不仅能够过滤较大体积的杂 质, 也能够过滤微小颗粒和可溶性污垢, 提升了水净化的效率, 在结构上, 无需增设水箱、 大型水处理设备等, 且由于一体化的设计, 减小了过滤器的 体积, 优化了洗衣机的布局空间, 使得洗衣机更为小型化。 附图说明

例如, 超滤膜组件 14可包覆在粗过滤组件 12的外围。也可以其他方式 实现粗过滤组件 12和超滤膜组件 14的一体化设置, 例如, 将超滤膜组件 14和粗过滤组件 12并排设置在一起, 只要能够使水流经过所述粗过滤组件 12处理后再经过超滤膜组件 14过滤即可。
在使用过程中, 粗过滤组件 12可用于过滤线屑以及较大颗粒, 而超滤 膜组件 14可用于过滤较小颗粒、可溶性污垢等, 设置粗过滤组件 12还可以 延长超滤膜组件 14的使用寿命。
通过以上方式将粗过滤组件 12和超滤膜组件 14一体化, 结构紧凑、体 积小, 且能同时实现粗过滤和精过滤, 水净化效果好。
粗过滤组件 12上设有水循环进口 121, 超滤膜组件 14上设有水循环出 口 142, 循环水可经由水循环进口 121首先进入粗过滤组件 12, 经粗过滤组 件 12进行粗过滤后, 经由粗过滤组件 12的过滤孔进入超滤膜组件 14进行 精过滤, 然后经由水循环出口 142重新进入循环通道, 以实现循环过滤。
过滤装置 10上设有进气口 143, 进气口 143可用于向超滤膜组件 14以 及粗过滤组件 12中输送气流,在对过滤装置 10进行清洗时, 可先通过气流 松落截留或粘附在超滤膜组件 14或粗过滤组件 12中的杂质,减少水洗过滤 装置 10的难度, 增强过滤装置 10的清洗效果。
可通过进入水循环进口 121的水, 分时对粗过滤组件 12和超滤膜组件 14进行水洗, 具体地, 在过滤装置 10可设置排水口 124和 144, 其中排水 口 124用于将清洗粗过滤组件 12的水排出过滤装置 10。 排水口 144用于将 清洗超滤膜组件 14的水排出过滤装置 10。
上述水循环进口 121、 进气口 143可设置在过滤装置 10的下端, 而水 循环出口 142、 排水口 124、 144设置在过滤装置 10的上端。 实施例二
上述过滤装置 10用于洗衣机时, 可结合洗衣机中相应的管路结构, 来 对洗涤筒的排出水进行循环过滤, 以实现利用净化回收水对衣物进行漂洗, 达到节水的效果。
图 2为本实施例二提供的一种洗衣机的可选结构图。如图 2所示, 该洗 衣机包括洗涤筒 21和排水口 22。 其中洗涤筒 21上设有清水进口, 通过管 路 a连接自来水口, 当打开管路 a上的阀门 1时, 可向洗涤筒 21中进洗涤 用清水或漂洗用清水。
该洗衣机还包括与洗涤筒 21连通的水循环管路, 该水循环管路上设有 过滤装置, 该过滤装置包括一体设置的粗过滤组件 12和超滤膜组件 14, 洗 涤筒 21的排出水依次经过粗过滤组件 12和超滤膜组件 14处理后回流至洗 涤筒 21。
例如, 图 2中的管路 b、 水泵 4、 管路 c、 三通阀 6、 管路 e、 管路 f、 三通阀 7以及管路 g连接形成水循环管路, 其中管路 b连通洗涤筒 21的排 水口, 管路 g连通洗涤筒 21的进水口。 管路 e和 f之间连接有一体设置的 粗过滤组件 12和超滤膜组件 14, 其中管路 e连通粗过滤组件 12的水循环 进口 121,管路 f连通超滤膜组件 14的水循环出口 142。上述水循环管路中, 靠近洗涤筒 21排水口的部分, 如管路 b、 c、 e, 形成洗涤筒 21的循环水出 水管路; 靠近洗涤筒 21进水口的部分, 如管路 f、 g, 形成洗涤筒 21的循环 水回水管路。
在洗衣流程中的洗涤或漂洗工序, 控制三通阀 6使管路 (:和6连通, 控 制三通阀 7使管路 f和 g连通, 并启动水泵 4, 使洗涤水或漂洗水经管路 b、 c. e,先从粗过滤组件 12的水循环进口 121进入粗过滤组件 12进行粗过滤, 再经由粗过滤组件 12进入超滤膜组件 14进行精过滤, 然后经水循环出口 142、 管路 f、 g回收至洗涤筒 21, 以再次用作衣物漂洗。
上述方案利用一体化设置的粗过滤组件和超滤膜组件依次对洗涤筒的 排出水进行循环过滤,不仅能够过滤较大体积的杂质, 也能够过滤微小颗粒 和可溶性污垢, 提升了水净化的效率, 在结构上, 无需增设水箱、 大型水处 理设备等, 且由于一体化的设计, 减小了过滤器的布局空间, 也使得洗衣机 更为小型化。
可选地,本实施例的洗衣机还包括洗衣用排水管路,通过三通阀分别连 接至洗涤筒 21排水口和粗过滤组件 12的水循环进口。例如, 图 2中的管路 d作为洗衣用排水管路, 一端连接洗衣机的排水口 22, 另一端通过三通阀 6 可连接管路 (:或^
在洗涤或者漂洗工序, 当需要将洗涤筒 21中的洗涤水或者漂洗水排出 洗衣机外时, 可控制三通阀 6使得管路 d和 C连通, 使得洗涤水或者漂洗水 不进入过滤装置 10, 而直接经管路 b、 c、 d排出洗衣机。
本实施例的洗衣机还包括浊度传感器 2, 设于洗涤筒 21 中。 上述浊度 传感器 2用于检测洗涤筒的洗涤水或漂洗水的浊度是否达到预设值。 例如, 在洗涤工序,若洗涤水的浊度未达到预设值, 则通过上述水循环管路回收洗 涤水, 进入洗涤循环阶段; 当检测到洗涤水达到预设值时, 控制洗涤水经上 述洗衣用排水管路排出洗衣机, 并进入漂洗工序。
在漂洗工序,执行一次漂洗后检测到漂洗水的浊度达到预设值, 则控制 漂洗水经上述洗衣用排水管路排出洗衣机, 否则,通过上述水循环管路回收 洗涤水, 进入漂洗循环阶段。
通过设置浊度传感器,使得可根据洗涤水或漂洗水的浊度情况自动判断 是否需要排水, 也可自动判断是否进入水过滤循环工序,提高洗衣机的智能 程度。

本实施例的洗衣机还包括第二清洗用排水管路,所述过滤装置上设有用 于将清洗粗过滤组件的水排出过滤装置的排水口,所述第二清洗用排水管路 一端连接所述过滤装置的排水口, 另一端连接所述洗衣机的排水口。 如图 2 中的管路 h、 k连接形成第二清洗用排水管路, 其中管路 h、 k分别与过滤 装置 10的排水口 124和洗衣机的排水口 22连通, 管路 h上设有阀门 5。 洗涤循环或漂洗循环完毕后, 可进入过滤装置 10 的清洗阶段, 包括气 洗和水洗。 在气洗阶段, 打开阀门 5、 单向阀 13和气泵 11, 气泵 11产生的 气流经管路 j进入过滤装置 10, 同时气冲洗粗过滤组件 12和超滤膜组件 14 的内部空腔, 形成气洗回路进行气洗。 气洗过滤装置 10可松落粘附或截留 在粗过滤组件 12和超滤膜组件 14上的线屑、 颗粒等污垢。
气洗结束, 对过滤装置 10进行水洗, 具体可同时或分时对粗过滤组件 12和超滤膜组件 14进行水洗。 水洗粗过滤组件 12时, 气泵 11关闭, 阀门 5开启, 排水泵 4打开, 控制三通阀 6使管路 (:和6导通, 关闭三通阀 7、 阀门 3, 则洗涤筒 21的排出水经管路 c、 e流经粗过滤组件 12后经管路 h、 k排出洗衣机, 将粗过滤组件 12中的污垢冲走。
对超滤膜组件 14进行水洗时, 气泵 11关闭, 阀门 3开启, 排水泵 4打 开, 控制三通阀 6使管路 (:和6导通, 关闭三通阀 7、 阀门 5, 则洗涤筒 21 的排出水经管路 (:、 e, 经粗过滤组件 12过滤后流经超滤膜组件 14, 最后经 管路 i、 k排出洗衣机, 将超滤膜组件 14表面的污垢冲走。
也可对粗过滤组件或所述超滤膜组件同时进行气洗和水洗,即向所述粗 过滤组件和超滤膜组件输送气体的同时,控制所述洗涤筒的排出水清洗所述 粗过滤组件或所述超滤膜组件后排出节水洗衣机。
因此, 通过设置气泵 11, 可利用气流松落截留或粘附在超滤膜组件 14 或粗过滤组件 12上的杂质, 使得水洗时杂质容易被水冲走, 增强清洗效果。 并且通过上述第一、 第二清洗用排水管路, 可分别实现针对粗过滤组件 12 和超滤膜组件 14的清洗, 延长过滤装置的寿命, 并且实现了过滤装置 10的 自清洗, 无需人工清理, 使洗衣机更为自动化。

在气洗过滤装置 10完毕后, 洗涤循环完毕后、 或者漂洗循环完毕后, 可用清水单独反向冲洗超滤膜组件 14或同时对粗过滤组件 12和超滤膜组件 14进行反向清洗。 反向清洗粗过滤组件 12时, 关闭三通阀 6, 关闭气泵 11、 控制三通阀 7使管路 L和管路 f连通, 打开阀门 5, 使自来水经管路1^、 f从过滤装置 10的水循环出口 142反向进入超滤膜组件 14,并经由超滤膜组件 14后进入 粗过滤组件 12, 以反向水洗超滤膜组件 14、 粗过滤组件 12, 之后, 经管路 h、 k排出洗衣机。 或者, 控制三通阀 6使管 6和(1连通、 控制三通阀 7使 管路 L和管路 f连通, 关闭气泵 11和单向阀 13, 关闭阀门 3、 阀门 5, 则 自来水经管路 L、 f从水循环出口 142反向进入超滤膜组件 14, 再经由超滤 膜组件 14后反向进入粗过滤组件 12, 以反向水洗超滤膜组件 14、粗过滤组 件 12, 之后, 经管路 e、 d排出洗衣机。
反向清洗超滤膜组件 14时, 关闭三通阀 6, 关闭气泵 11、 控制三通阀 7使管路 L和管路 f连通, 打开阀门 3、 关闭阀门 5, 使自来水经管路1、 f 从过滤装置 10的水循环出口 142反向进入超滤膜组件 14, 以水洗超滤膜组 件 14, 之后, 经管路 i、 k排出洗衣机。
