本发明提供了一种洗衣机， 包括第一水循环通道，该第一水循环通道 的一端设有喷淋头， 另一端连通洗衣机的洗涤筒， 喷淋头用于将从洗衣机 的洗涤筒排出到第一水循环通道中的水，顺着洗涤筒旋转时产生的涡流的 切面喷淋至洗涤筒内。
从洗衣机的洗涤筒排出到第一水循环通道中的水，可以是由于重力作 用从洗衣机洗涤筒流入第一水循环通道的水，也可是通过例如水泵将从洗 涤筒排出到第一水循环通道的水，还可为洗涤筒在高速旋转时因离心作用 从洗涤筒中甩出的水， 本发明不对其进行特别限定。
"顺着洗涤筒旋转时产生的涡流的切面喷淋至洗涤筒内 "， 使得在洗 涤筒高速旋转时，可避免喷淋头喷出的水受气流阻挡，并且可均匀地从洗 涤筒的开口端覆盖至洗涤筒的后挡盖处，使得能够均匀地覆盖洗涤筒中的 衣物。 在一种情况下， 通过这种方式， 可使得喷淋出的水沿着洗涤筒的内 壁均匀覆盖至衣物，或者基本平行于高速旋转的洗涤筒的内壁均匀覆盖至 衣物。
例如， 图 1所示的洗衣机包括洗涤筒 3、 外桶 4、 水泵 6、 送水管路 12、 第一换向阀 7、 循环管路 14、 喷淋头 11。 其中外桶 4的出水口、 水 泵 6、 送水管路 12、 第一换向阀 7、 循环管路 14、 喷淋头 11依次形成第 一水循环通道。 喷淋头 1设在第一水循环通道的一端，洗涤筒 3和第一水循环通道的 另一端连通， 即和外桶 4的出水口连通。水泵 6用于在第一水循环通道导 通时将洗涤筒 3中的水排出到第一水循环通道中，具体地， 水泵 6用于将 洗涤筒 3中水经外桶 4的出水口、 水泵 6、 送水管路 12、 第一换向阀 7、 循环管路 14引至喷淋头 11， 喷淋头 11用于将排出到第一 7^环通道中 的水喷淋至洗涤筒 3中。
通过设置喷淋头 11， 可增加水与衣物的接触面积， 衣物透水的均匀 度， 进而提升洗净率。
本实施例中， 通过设置喷淋头的朝向和位置， 使得喷淋头 11顺着洗 涤筒 3旋转时产生的涡流的切面向洗涤筒 3内部喷淋循环水。上述涡流的 切面， 可从洗涤筒的开口端处延伸至洗涤筒的后挡盖处， 上述洗涤筒 3 的内部， 可为从洗涤筒 3的开口处至洗涤筒 3的后挡盖处之间的空间。

图 2为图 1中的喷淋头结构示意图。如图 2所示，本实施例的喷淋头 11具有扁平状的喷口， 具体为： 喷口的横截面的高度小于横截面的宽度， 喷口的横截面指垂直于水流方向的截面例如 a-b、 c-f之间的距离小于 a-c 之间的 ii巨离。
更具体地， 喷口的纵截面沿水流方向（由后端至前端）宽度渐宽， 喷 口的纵截面指与水流方向平行的截面， 例如 a-c之间的距离大于 d-e之间 的距离； 喷口的横截面由一侧到另一侧高度渐小， 例如 a-b 的距离大于 c-f的 ii巨离。
通过以上方式设计喷淋头 11的结构， 可提升喷淋出的循环水的运动 速度，使其更快速地喷淋至洗涤筒的衣物中，并且能够保证更多的循环水 能够顺着涡流切面喷淋， 另外能进一步使循环水均匀地喷淋至衣物。
可选地， 在上述方案的基础上， 本发明还可包括第二水循环通道， 第 二水循环通道设有对洗涤筒排出的水进行过滤的过滤组件。 例如， 图 1 中的洗衣机还包括： 过滤管路 13、 过滤组件 9、 回流管路 18、 洗涤剂投 放盒 2、 其中， 外桶 4的排水口—水泵 6--送水管路 12--第一换向阀 7--过 滤管路 13-过滤组件 9-回流管路 18 洗涤剂投放盒 2-外桶 4的进水口等 形成两端均与洗涤筒 3连通的第二水循环通道。
第二水循环通道导通时，洗涤筒 3中的水在水泵 6的作用下排出到第 二水循环通道， 或者以其它方式排出至第二水循环通道。 具体地， 将洗涤 筒 3中的水经外桶 4的排水口—水泵 6--送水管路 12--第一换向阀 7--过滤 管路 13-过滤组件 9-回流管路 18 洗涤剂投放盒 2引至外桶 4的进水口， 然后流入洗涤筒 3， 其中过滤组件 9具体为滤膜， 用于对在洗涤筒 3排出 的水进行过滤。 通过过滤组件， 可过滤掉循环水中的线屑、 绒毛等， 有利 于净化循环水， 提升循环水的利用率， 提升洗净率。
具体地，过滤组件 9设置有至少一个进口和至少一个出口，该至少一 个进口可包括， 例如连通过滤管路 13的进口以及连通气泵 8的进口， 该 至少一个出口包括， 例如连通清洗管路 17的出口。
过滤组件 9的任一出口通向洗衣机夕卜的管路形成有第一排水通道，如 图 1所示， 该第一排水通道为， 例如， 清洗管路 17、 第二换向阀 10、 第 一排水管路 16、 洗衣机的排水口等形成的通道。
该第一排水通道具体可用于将清洗过滤组件 9后的污水经洗衣机的 排水口排出洗衣机外。
具体地，清洗过滤组件时，可先开启上述气泵 8对过滤组件 9进行气 洗， 气洗完成后对过滤组件 9进行水洗。也可同时执行气洗和水洗， 或者 间隔执行气洗、 水洗。
气洗时， 气泵 8作为气体输送装置，用于通过连通其的进口向过滤组 件中输送气体， 过滤组件在气流的震动作用下， 可使截留在过滤组件 9 上的线屑、 绒毛等松动， 使得在水洗过滤组件时， 线屑、 绒毛等容易随水 流排出， 延长过滤组件的使用寿命。
水洗时， 从洗涤筒 3内 清洗用水， 将清洗用 ^出洗涤筒 3， 该 清洗用水经过外桶 4的出水口、 水泵 6、 第一换向阀 7、 清洗管路 13， 从 连通清洗管路 13的进口进入过滤组件 9， 则过滤组件中的线屑、 绒毛等 随着清洗用水一起， 经过滤组件 9 的出口以及第一排水通道排出洗衣机 外。
可选地，还可设置用于检测过滤组件 9的滤膜两端压力差的压力传感 器（图中未示出）， 通过洗衣机的控制器接收压力传感器的检测结果， 例 如在检测滤膜两端压力差达到预设值时， 自动执行过滤组件 9 的清洗程 序， 使得第一排水通道导通， 避免损坏过滤组件。
可选地，本发明的洗衣机还包括：连通洗涤筒以将洗涤筒中的水排出 洗衣机外的第二排水通道。例如， 图 1中的洗衣机还包括连接第一换向阀 7和第二换向阀 10的第二排水管路 15。 其中外桶 4的排水口 送水管路 12-第一换向阀 7-第二排水管路 15-第二换向阀 10-第一排水管路 16等 形成第二排水通道。该第二排水通道用于在排水过程中导通， 以将洗涤筒 3中的水排出洗衣机外，具体地， 洗涤筒 3中的水经水泵 6、送水管路 12、 第一换向阀 7、 第二排水管路 15、 第二换向阀 10、 第一排水管路 16排出 洗^ L夕卜。
可选地， 图 1中的洗衣 ϋ£包括： 用于检测从洗涤筒 3中排出的水的 浊度的浊度传感器 5，和 /或用于检测从洗涤筒 3中排出的水的温度的温度 传感器 20。 本实施例中， 浊度传感器 5和 /或温度传感器 20设置在外筒 4 的出水口处。
浊度传感器 5和温度传感器 20可分别将检测结果发送至洗衣机的控 制器， 以通过控制器对洗衣机进行相应的控制， 例如， 洗衣机的控制器可 在检测的浊度值达到预设值时， 控制第一水循环通道关闭以停止循环喷 淋，并导通第二水循环通道对洗涤筒中排出的水进行循环过滤。在检测的 温度值达到预设值时，控制洗衣机的加热装置停止加热或者根据洗涤水的 温度判断是否需要循环过滤水。
本实施例中，将浊度传感器和温度传感器设置在第一水循环通道连通 洗涤筒 3的一端（如外桶 4的出水口处）， 检测的准确度较高， 便于快速 根据检测结果对做出相应的控制， 提升洗衣效率。
上述第一水循环通道、第二水循环通道、第一排水通道和第二排水通 道可相互独立。如图 1所示，也可部分重合并通过如电磁阀或换向阀等开 关单元在各通道的分叉部位进行选通控制。
在本实施例中，根据图 1所示的洗衣机，本发明还包括将洗涤筒中的 水排出洗涤筒的水泵， 如水泵 6。
可选地，本发明还包括连接上述第一水循环通道、第二水循环通道和 第二排水通道的第一开关单元， 如第一换向阀 7。
可选地，本发明还包括连接上述第二排水通道、第一排水通道的第二 开关单元， 如第二换向阀 10。 洗衣机各部件的具体布局位置可根据实际需要设计，本发明对此不进 行限制。本发明实施例提供的洗衣机可用于实现本发明实施例提供的洗衣 控制方法，其洗衣控制流程原理及可实现的技术效果可参见上文实施例的 相应记载。
本发明还提供一种洗衣控制方法， 包括：
通过设置在洗衣机的第一水循环通道一端的喷淋头，将从洗衣机的洗 涤筒排出到所述第一水循环通道中的水，顺着所述洗涤筒旋转时产生的涡 流的切面喷淋至所述洗涤筒内。
例如， 图 3为本发明实施例二提供的洗衣控制方法。本实施例的洗衣 控制方法可采用实施例一的洗衣机进行洗衣。
如图 3所示， 该洗衣控制方法包括以下步骤：
步骤 S10: 通过设置在第一水循环通道一端的喷淋头 11将从洗衣机 的洗涤筒 3排出到第一水循环通道的水，顺着洗涤筒 3旋转时产生的涡流 的切面喷淋至洗涤筒 3内。
如图 3所示，该步骤 S10可以在进行一段时间的洗涤程序后执行，执 行步骤 S10之后，可执行排水程序，将洗涤筒中的水通过排水通道排出洗 衣机。
上述 "从洗衣机的洗涤筒排出到第一 环通道中的水"， 可以是由 于重力作用从洗衣机洗涤筒流入第一水循环通道的水，也可是通过例如水 泵从洗涤筒排出到第一水循环通道的水，还可为洗涤筒在高速旋转时因离 心作用从洗涤筒中甩出的水， 本发明不对其进行特别限定。
"顺着洗涤筒旋转时产生的涡流的切面喷淋至洗涤筒内 "， 使得在洗 涤筒高速旋转时，可避免喷淋头喷出的水受气流阻挡，并且可均匀地从洗 涤筒的开口端覆盖至洗涤筒的后挡盖处，使得能够均匀地覆盖洗涤筒中的 衣物。 在一种情况下， 通过这种方式， 可使得喷淋出的水沿着洗涤筒的内 壁均匀覆盖至衣物，或者基本平行于高速旋转的洗涤筒的内壁均匀覆盖至 衣物。
步骤 S10中， 喷淋头 11设置在洗涤筒开口端的斜上方将从洗涤筒 3 排出至第一水循环通道中的水，顺着洗涤筒寻转时产生的涡流的切面喷淋 至洗涤筒 3内。 具体地， 当洗涤筒 3逆时针旋转时， 喷淋头 11在洗涤筒 3开口端的右上方顺着洗涤筒 3中的涡流切面向洗涤筒 3内喷淋循环水。 步骤 S10中采用的喷淋头 11， 其喷口的横截面的高度小于横截面的 宽度。
步骤 S10中采用的喷淋头 11， 其喷口的纵截面由前端至后端宽度渐 小、 横截面由一侧到另一侧高度渐小。
步骤 S10可避免由于喷淋出的循环水受气流阻挡，并且可增加喷淋水 向洗涤筒内运动的速度，使得衣物能够更快速渗水，还可进一步增加水与 衣物的接触面积。
可选地， 本实施例的洗衣控制方法还包括：
过滤步骤： 通过设置在洗衣机的第二水循环通道中的过滤组件 9， 对 从洗涤筒 3排出到第二水循环通道的水进行过滤处理。
过滤步骤可过滤掉循环水中的线屑、绒毛或其它大分子颗粒，有利于 净化循环水， 提升循环水的利用率， 提升洗净率。
可选地， 本实施例的洗衣控制方法还包括：
气洗步骤： 经过滤组件 9的任一进口向过滤组件 9输送气体；本步骤 可通过连通过滤组件的气泵 8来实现。
水洗步骤： 将洗涤筒 3中的水排出至过滤组件 9， 并经过滤组件 9的 任一出口与洗衣机外的管路形成的第一排水通道将流经过滤组件 9 的水 排出洗衣机。
具体可在清洗过滤组件 9时分时或同时执行气洗步骤和水洗步骤。因 此可在步骤 S10、 过滤步骤之前、 之后或之间来执行。 气洗和水洗结合的 方式与单独的水洗过滤组件相比， 能够节省冲洗水， 而且克服了单独水洗 时，污物在超滤膜上不易冲洗掉的缺点，能将超滤膜清洗的更干净、彻底。
可选地， 本实施例的洗衣控制方法还包括：
压力差检测步骤： 通过压力传感器检测过滤组件 9 滤膜两端的压力 差， 根据检测的压力差确定是否进行过滤组件的清洗。
例如，如果过滤组件 9滤膜两端的压力差大于预设值，则说明过滤组 件截留的杂质过多， 因此通过执行压力差检测，可判断滤膜当前的清洁程 度，进一步，可根据滤膜当前的清洁程度自动判断是否需要启动对过滤组 的针对性和及时性， 防止滤膜上截留的污物过多，有利于延长过滤组件的 使用寿命。 因此， 除了在预设的程序中清洗过滤组件外， 还可在判断过滤 组件的清洁程度低时自动启动对过滤组件的清洗。
可选地， 本实施例的洗衣控制方法还包括浊度检测步骤和 /或温度检 测步骤：
浊度检测步骤： 通过浊度传感器检测从洗涤筒 3中排出的水的浊度， 根据检测的浊度值确定是否将洗涤筒内的水经第二水循环通道回流至洗 涤筒中；
温度检测步骤： 通过温度传感器检测从洗涤筒 3中排出的水的温度， 根据检测的温度值确定是否对洗涤筒 3中的水进行加热。
检测的浊度值和温度值可发送至洗衣机的控制器，以使其对洗衣机执 行相应的控制， 例如， 洗衣机的控制器可在检测的浊度值达到预设值时， 控制第二水循环通道导通以对洗涤筒 3中的水进行循环过滤。在检测的温 度值达到预设值时， 控制洗衣机的加热装置停止加热。
上述任一步骤都可在例如洗涤、 漂洗、 脱水等任一阶段来执行。
本发明的洗衣机以及洗衣控制方法通过喷淋头将从洗涤筒排出至第 一水循环通道中的水均勾地喷淋至洗涤筒中的衣物中，可增加水与衣物的 接触面积， 衣物透水的均匀度， 进而提升洗净率。 并且使得喷淋头顺着洗 涤筒旋转时产生的涡流的切面喷淋至洗涤筒内，可增加喷淋水向洗涤筒内 运动的速度，使得衣物能够更快速渗水，还可进一步增加水与衣物的接触 面积。可提高循环喷淋时所进清水的利用率，使得采用相同清水量可去除 更多的洗涤物质残留， 满足衣物清洁度的同时尽可能的减少了用水量。
虽然已经详细说明了本发明及其优点，但是应当理解在不脱离由所附 的权利要求所限定的本发明的精神和范围的情况下可以进行各种改变、替 代和变换。
最后， 还需要说明的是， 在本文中， 诸如第一和第二等之类的关系术 语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定 要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而 且， 术语"包括"、 "包含"或者其任何其他变体意在涵盖非排他性的包含， 从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素， 而且还包括没有明确列出的其他要素， 或者是还包括为这种过程、 方法、 物品或者设备所固有的要素。 在没有更多限制的情况下， 由语句 "包括一 个 ......
