图 1为本发明实施例一提供的洗衣机洗衣控制方法的流程图。如图 1 所示， 本实施例提供的洗衣机洗衣控制方法包括：
步骤 11： 检测是否有水循环使用的指令输入。
水循环使用的指令的输入方式不受限制，例如： 可通过洗衣机的操作 面板或显示面板输入水循环使用的指令，或者，通过物联网向洗衣机输入 环使用的指令等。
步骤 12: 如果有所述指令输入， 则根据洗衣用水的检测参数或者根 据洗衣流程中在先洗衣程序关于循环水的使用情况， 自动选择在洗衣流程 的某一洗衣程序中是否使用循环水。
对于没有水循环使用的指令输入的情形下洗衣机的控制处理方式，本 发明对此不进行限制，例如一种可选的实现方式例如： 可等待一段时间之 后， 继续执行步骤 11， 直至检测到有水循环使用的指令输入时执行步骤
12等。
本实施例提供的技术方案在检测到有水循环使用的指令输入的情形 下，一定程度上相当于洗衣机可根据实际情况（如检测参数或在先洗衣程 序关于循环水的使用情况等）对水循环使用的指令起到自驗证或自适配， 自动选择在某一洗衣程序中是否使用循环水，以得到优选的水循环洗衣方 案（如自，选，在洗衣流程的某一洗衣程序中是，使用循环水）。 因此 1， 实现方式灵活， 更好满足了实际应用的需求。
上述技术方案中，所述检测参数可包括但不限于： 洗衣用水的浊度和 /或温度。 所述洗衣流程的洗衣程序可包括以下之一或任意组合： 洗涤程 序、 漂洗程序、 甩干程序。
所述洗衣流程的在先洗衣程序可包括：相对洗衣流程中的某一洗衣程 序而言，按照洗衣控制流程逻辑上洗衣机要先执行或者实际已经在先执行 的洗衣程序。 例如： 相对甩干程序而言， 洗涤程序和 /或漂洗程序通常为 在先洗衣程序。
所述的循环水包括：洗衣流程中经洗衣筒排出或甩出的洗衣用水的净 化水或再次利用水， 其中， 净化水为： 洗衣筒排出或甩出的洗衣用水经如 过滤组件等进行净化处理后的水，再次利用水为： 洗衣筒排出或甩出的洗 衣用水未经净化处理而经管路回流到洗衣筒的水。下面对循环水的可选含 义进行举例说明， 但以下例子不应理解为对本发明技术方案的限制。
例如， 所述循环水包括洗涤或漂洗（不妨表示为洗涤 /漂洗）过程中 经洗衣筒排出的洗衣用水的净化水， 如： 洗涤 /漂洗过程中经洗衣筒排出 的洗衣用水经过滤组件过滤处理后通过循环管路再次回流到洗衣筒内，实 现洗衣用水的净化循环使用。
又例如，所述循环水包括甩干过程中经洗衣筒排出的洗衣用水的再次 利用水，如： 甩干过程中将洗衣筒旋转甩出的水通过循环管路再次回流到 洗衣筒内， 实现洗衣用水的再次利用。
图 2为本发明实施例二提供的洗衣机洗衣控制方法的流程图。本实施 例中检测参数为洗衣用水的浊度，并以在洗涤程序或漂洗程序中的洗衣控 制为例进行说明。如图 2所示，本实施例提供的洗衣机洗衣控制方法包括： 步骤 21: 检测是否有水循环使用的指令输入。
步骤 22: 如果有所述指令输入， 则检测洗衣用水的浊度， 将得到的 浊度检测值与预定的浊度阈值进行比较，如果所述浊度检测值小于所述浊 度阈值， 则自动选择在洗涤程序或漂洗程序中使用循环水， 否则， 自动选 择在洗涤程序或漂洗程序中不使用循环水。
可通过浊度传感器对洗衣用水的浊度进行检测，浊度阈值可根据实际 需要预先设置， 如根据衣物洗净率的实际要求预先设置。 可选的， 可在洗 序或漂洗程序执行一定时长后，检测当前洗衣用水的浊度。如果浊度 检测值小于浊度阈值，说明当前洗衣用水较脏，该情形下可优先考虑衣物 洗净率的要求， 洗衣机自动选择不使用循环水， 而将洗衣用水排出洗衣机 外。 如果浊度检测值大于或等于浊度阈值， 说明当前洗衣用水较为干净， 该情形下可优先考虑洗衣节水量， 洗衣机自动选择使用循环水，经洗衣筒 排出的洗衣用水经过滤组件过滤处理后再次回流到洗衣筒内循环使用。
可见，本实施例在检测到有水循环使用的指令输入时，根据洗衣用水 的浊度自动选择是否在当前洗衣程序（如洗涤程序或漂洗程序 )中使用循 环水，有利于在实际洗衣流程权衡衣物洗净率和洗衣用水量， 达到一定衣 物洗净率的同时尽可能节约用水量。 因此，本实施例可对洗衣机使用循环 水进行节水洗衣的洗衣流程实现智能控制， 实现方式灵活， 更好满足了实 际应用的需求。
图 3为本发明实施例三提供的洗衣机洗衣控制方法的流程图。本实施 例中检测参数为洗衣用水的温度，并以在洗涤程序或漂洗程序中的洗衣控 制为例进行说明。如图 3所示，本实施例提供的洗衣机洗衣控制方法包括： 步骤 31: 检测是否有水循环使用的指令输入。 步骤 32: 如果有所述指令输入， 则检测洗 序或漂洗程序中洗衣 用水的温度，如果所述温度检测值小于所述浊度阈值，则自动选择在洗涤 程序或漂洗程序中使用循环水，否则，在洗涤程序或漂洗程序中不使用循 环水。
本实施例中洗衣机可具有过滤组件过滤处理、加热等功能。温度阈值 可根据实际需要预先设置，如根据对洗衣用水进行过滤处理的过滤组件的 耐温阈值预先设置， 温度阈值小于或等于过滤组件的耐温阈值。
对洗衣用水进行过滤处理的过滤组件通常有一定的耐温阈值，预先设 置的温度阈值小于或等于过滤组件的耐温阈值。如果在洗衣流程中启用了 加热功能或使用温度较高的洗衣用水，则在检测到有水循环使用的指令输 入时，可通过温度传感器对洗衣用水的温度进行检测。如果洗衣用水的温 度检测值小于温度阈值， 则自动选择在洗涤程序或漂洗程序中使用循环 水， 以节省洗衣用水量； 如果洗衣用水的温度检测值大于温度阈值， 则自 动选择在洗涤程序或漂洗程序中不使用循环水，以避免温度过高的洗衣用 水经过滤组件过滤处理的过程中对过滤组件造成损坏。
本实施例中，对洗衣用水温度的检测可在洗涤程序或漂洗程序执行一 定时长后执行一次。 或者， 在洗 序或漂洗程序中多次检测， 根据各次 检测到的洗衣用水的温度检测值和温度阈值的比较结果，及时调整在洗涤 程序或漂洗程序中是否使用循环水； 例如，如果当前温度检测得到温度检 测值小于温度阈值，则洗衣机自动选择在洗涤程序或漂洗程序中使用循环 水，如果下一次温度检测得到温度检测值大于或等于温度阈值，则此时洗 衣机自动选择在洗 序或漂^^呈序中不使用循环水。
可见，本实施例在检测到有水循环使用的指令输入时，根据洗衣用水 的温度自动选择是否在当前洗衣程序 (如洗涤程序或漂洗程序 )中使用循 环水，有利于在实际洗衣流程中自动避免温度过高的洗衣用水经过滤组件 过滤处理的过程中对过滤组件造成损坏。 因此，本实施例可对洗衣机使用 循环水进行节水洗衣的洗衣流程实现智能控制， 实现方式灵活， 更好满足 了实际应用的需求。
图 4为本发明实施例四提供的洗衣机洗衣控制方法的流程图。本实施 例中检测参数为洗衣用水的温度和浊度，并以在洗涤程序或漂洗程序中的 洗衣控制为例进行说明。如图 4所示，本实施例提供的洗衣机洗衣控制方 法包括： 步骤 41: 检测是否有水循环使用的指令输入。
步骤 42: 如果有所述指令输入， 则检测洗 序或漂洗程序中洗衣 用水的温度， 将得到的温度检测值与预定的温度阈值进行比较。
步骤 43: 如果所述温度检测值小于所述温度阈值， 则在洗涤程序或 漂洗程序执行一定时长后检测洗衣用水的浊度，将得到的浊度检测值与预 定的浊度阈值进行比较，如果所述浊度检测值小于所述浊度阈值，则自动 选择在洗涤程序或漂洗程序中使用循环水， 否则，在洗涤程序或漂洗程序 中不使用循环水。
步骤 44: 如果所述温度检测值大于所述温度阈值， 则自动选择在洗 序或漂^ ^呈序中不使用循环水。
本实施例在检测到有水循环使用的指令输入时，结合温度检测和浊度 检测的结果，作为在洗涤程序或漂洗程序是否使用循环水的判断依据。温 度阈值可根据实际需要预先设置，如根据对洗衣用水进行过滤处理的过滤 组件的耐温阈值预先设置，温度阈值小于或等于过滤组件的耐温阈值。 浊 度阈值可根据实际需要预先设置， 如根据衣物洗净率的实际要求预先设 置。
如果洗衣用水的温度检测值小于温度阈值，说明此时洗衣用水温度不 会对如过滤组件等部件造成损坏，在此前提下，进一步比较浊度检测值和 浊度阈值， 如果浊度检测值小于浊度阈值， 说明当前洗衣用水较脏， 该情 形下可优先考虑衣物洗净率的要求， 洗衣机自动选择不使用循环水， 而将 洗衣用 ^出洗衣机外。如果浊度检测值大于或等于浊度阈值，说明当前 洗衣用水较为干净，该情形下可优先考虑洗衣节水量， 洗衣机自动选择使 用循环水，经洗衣筒排出的洗衣用水经过滤组件过滤处理后再次回流到洗 衣筒内循环使用。
如果洗衣用水的温度检测值大于或等于温度阈值，说明此时洗衣用水 温度会对如过滤组件等部件造成损坏，此时自动选择在洗涤程序或漂洗程 序中不使用循环水，以避免温度过高的洗衣用水经过滤组件过滤处理的过 程中对过滤组件造成损坏。
可见，本实施例在检测到有水循环使用的指令输入时，根据洗衣用水 的温度和浊度自动选择是否在当前洗衣程序（如洗涤程序或漂洗程序 )中 使用循环水，有利于在实际洗衣流程中自动避免温度过高的洗衣用水经过 滤组件过滤处理的过程中对过滤组件造成损坏，在此基础上进一步在实际 洗衣流程权衡衣物洗净率和洗衣用水量，以达到一定衣物洗净率的同时尽 可能节约用水量。 因此，本实施例可对洗衣机使用循环水进行节水洗衣的 衣流程实 ^智能控制 实现: ^式 活， 更好，足了 -实际应用的需求、。 当 图 5为本发明实施例五提供的洗衣机洗衣控制方法的流程图。如图 5 所示， 本实施例提供的洗衣机洗衣控制方法包括：
步骤 51: 检测是否有水循环使用的指令输入。
步骤 52: 如果有所述指令输入， 则确定在洗涤程序中是否使用了循 环水， 如果是， 则自动选择在甩干程序中使用循环水。
洗涤程序中如果使用循环水， 说明洗衣流程中使用的清水总量很少。 洗涤程序中使用的循环水通常是将洗衣用水经过滤组件过滤处理后的净 化水， 而过滤组件通常是滤除洗衣用水中的线屑、 大颗粒物等杂质， 洗衣 用水中溶水性物质很难滤除，故对于洗衣程序中使用循环水及其类似采用 清水总量很少的情形， 衣物洗涤物质的残留（如碱度残留）通常较多， 此 时可自动选择在甩干程序中使用循环水，该循环水为甩干程序中经洗衣筒 甩出的洗衣用水的再次利用水。
所述自动选择在甩干程序中使用循环水一种可选实现方式例如：采用 在甩干程序中进行喷淋脱水处理， 以减少衣物洗涤物质的残留（如减少衣 物的碱度残留）。
在甩干程序中可执行一次喷淋脱水处理，或者执行多次喷淋脱水处理 以进一步减少衣物的碱度残留。每次喷淋脱水处理包括： 向滚筒内进一定 量清水，使滚筒旋转，导通洗衣机的水循环通道以将滚筒旋转过程中甩出 的水引至喷淋头并喷淋至滚筒内的衣物上，如此水循环一定时长后，继续 使滚筒旋转并将滚筒旋转过程中甩出的 7j #出洗 ^外 在每次进行喷淋 脱水处理时， 滚筒旋转过程产生的高速离心作用将喷淋在衣物上的水甩 出， 甩出的水带走衣物上残留的洗涤物质的同时回流到喷淋头再次利用， 如此水循环可逐渐减少衣物上洗涤物质的残留，有效降低衣物上的碱度残 留。
可见，本实施例在检测到有水循环使用的指令输入时，如果洗涤程序 中使用了循环水， 则自动选择在甩干程序中使用循环水，提高了当前甩干 程序中每次喷淋脱水处理所进的清水的利用率，使得采用相同清水量可去 除更多的洗涤物质残留， 满足衣物洗净率的同时尽可能的减少了用水量。 因此，本实施例可对洗衣机使用循环水进行节水洗衣的洗衣流程实现智能 控制， 实现方式灵活， 更好满足了实际应用的需求。
图 6为本发明实施例六提供的洗衣机洗衣控制方法的流程图。如图 6 所示， 本实施例提供的洗衣机洗衣控制方法包括：
步骤 61: 检测是否有水循环使用的指令输入。
步骤 62: 如果有所述指令输入， 则确定在漂洗程序中是否使用了循 环水， 如果是， 则自动选择在甩干程序中不使用循环水。
衣物洗涤物质的残留（如碱度残留）通常和洗衣流程中使用的清水总 量有关， 当洗衣流程中使用的清水满足一定量时， 衣物洗涤物质的残留通 常较小。 漂^ f呈序中如果使用循环水， 通常在洗;^呈序中不使用循环水， 故洗衣流程中使用的清水总量相对较多。故，如果检测到有水循环使用的 指令输入且在漂洗程序中使用了循环水，则自动选择在甩干程序中不使用 循环水的方式进行脱水处理。
可见，本实施例在检测到有水循环使用的指令输入时，如果漂洗程序 中使用了循环水， 则自动选择不在甩干程序中使用循环水，有利于在实际 洗衣流程权衡衣物洗净率和洗衣用水量，达到一定衣物洗净率的同时尽可 能节约用水量。 因此，本实施例可对洗衣机使用循环水进行节水洗衣的洗 衣流程实现智能控制， 实现方式灵活， 更好满足了实际应用的需求。
图 7为本发明实施例七提供的洗衣机的原理框图。如图 7所示，本实 施例提供的洗衣机包括： 检测模块 71和自动选择模块 72。
检测模块 71用于检测是否有水循环使用的指令输入。
自动选择模块 72用于如果有所述指令输入， 则根据洗衣用水的检测 或者根据洗衣流程中在先洗衣程序关于循环水的使用情况， 自动选择 在洗衣流程的某一洗衣程序中是否使用循环水。
所述循环水包括：洗衣 中经洗衣筒排出或甩出的洗衣用水的净化 水或再次利用水。
本实施例提供的洗衣机可检测是否有水循环使用的指令输入，并在有 该指令输入的情形下，根据洗衣实际情况（如检测参数或洗衣流程中在先 洗衣程序关于循环水的使用情况等）自动选择在某一洗衣程序中是否使用 循环水， 以得到优选的水循环洗衣方案（如自动选择在洗衣流程的某一洗 衣程序中是否使用循环水）。 因此， 本实施例可对洗衣机使用循环水进行 节水洗衣的洗衣流程实现智能控制， 实现方式灵活， 更好满足了实际应用 的需求。
可选的， 所述检测参数包括： 洗衣用水的浊度。 所述自动选择模块包 括： 第一自动选择单元。 第一自动选择单元用于如果有所述指令输入， 则 检测洗衣用水的浊度， 将得到的浊度检测值与预定的浊度阈值进行比较， 如果所述浊度检测值小于所述浊度阈值，则自动选择在洗涤程序或漂洗程 序中使用循环水，否则，自动选择在洗涤程序或漂洗程序中不使用循环水。 第一自动选择单元可在洗涤程序或漂洗程序执行一定时长后进行洗衣用 水浊度的检测。该方案有利于在实际洗衣流程权衡衣物洗净率和洗衣用水 量， 达到一定衣物洗净率的同时尽可能节约用水量。 因此， 该方案可对洗 衣机使用循环水进行节水洗衣的洗衣流程实现智能控制， 实现方式灵活， 更好满足了实际应用的需求。
可选的， 所述检测参数包括： 洗衣用水的温度。 所述自动选择模块包 括： 第二自动选择单元。 第一自动选择单元用于如果有所述指令输入， 则 检测洗涤程序或漂洗程序中洗衣用水的温度，如果所述温度检测值小于所 述温度阈值， 则自动选择在洗涤程序或漂洗程序中使用循环水， 否则， 在 洗涤程序或漂洗程序中不使用循环水。该方案有利于在实际洗衣流程中自 动避免温度过高的洗衣用水经过滤组件过滤处理的过程中对过滤组件造 成损坏。 因此，该方案可对洗衣机使用循环水进行节水洗衣的洗衣流程实 现智能控制， 实现方式灵活， 更好满足了实际应用的需求。
可选的， 所述检测参数包括： 洗衣用水的温度和浊度。 所述自动选择 模块包括： 第三自动选择单元。第三自动选择单元用于如果有所述指令输 入，则检测洗涤程序或漂洗程序中洗衣用水的温度，将得到的温度检测值 与预定的温度阈值进行比较； 如果所述温度检测值小于所述温度阈值， 则 在洗涤程序或漂洗程序执行一定时长后检测洗衣用水的浊度，将得到的浊 度检测值与预定的浊度阈值进行比较，如果所述浊度检测值小于所述浊度 阈值， 则自动选择在洗涤程序或漂洗程序中使用循环水， 否则， 在洗涤程 序或漂洗程序中不使用循环水； 如果所述温度检测值大于所述温度阈值， 则自动选择在洗涤程序或漂洗程序中不使用循环水。该方案有利于在实际 洗衣流程中自动避免温度过高的洗衣用水经过滤组件过滤处理的过程中 对过滤组件造成损坏，在此基础上进一步在实际洗衣流程权衡衣物洗净率 和洗衣用水量， 以达到一定衣物洗净率的同时尽可能节约用水量。 因此， 该方案可对洗衣机使用循环水进行节水洗衣的洗衣流程实现智能控制，实 现方式灵活， 更好满足了实际应用的需求。
可选的， 所述自动选择模块包括： 第四自动选择单元。 第四自动选择 单元用于如果有所述指令输入， 则确定在洗涤程序中是否使用了循环水， 如果是， 则自动选择在甩干程序中使用循环水。 例如， 所述第四自动选择 单元，具体用于如果有所述指令输入，则确定在洗涤程序中是否使用了循 环水， 如果是， 则自动选择在甩干程序中进行至少一次喷淋脱水处理， 并 在每次喷淋脱水处理中使用循环水。该方案提高了当前甩干程序中每次喷 淋脱水处理所进的清水的利用率，使得采用相同清水量可去除更多的洗涤 物质残留， 满足衣物洗净率的同时尽可能的减少了用水量。该方案可对洗 衣机使用循环水进行节水洗衣的洗衣流程实现智能控制， 实现方式灵活， 更好满足了实际应用的需求。
下面不妨以图 8为例，对依据本发明提供的技术方案可能形成的洗衣 流程进行示例性说明。本发明实施例提供的洗衣机包括检测模块和自动选 择模块， 此外， 如图 8所示， 洗衣机还包括进水阀 1、 洗涤剂投放盒 2、 滚筒 3、 外桶 4、 浊度传感器 5、 水泵 6、 第一换向阀 7、 气泵 8、 过滤组 件 9、 第二换向阀 10、 喷淋头 11、 送水管路 12、 过滤管路 13、 循环管路 14、 第一排水管路 15、 第二排水管路 16、 清洗管路 17、 回流管路 18、 第 一压力传感器 19、 第二压力传感器 20和温度传感器 21。
洗衣机的检测模块在检测到有水循环使用的指令输入时，自动选择模 块自动选择在洗衣流程的某一洗衣程序中是否使用循环水。洗衣机在检测 到有水循环使用的指令输入时执行的可选的洗衣流程例如：
清水经过进水阀 1进入到洗涤剂投放盒 2，将洗涤剂冲入到洗涤滚筒 3内， 参与洗涤。
进水结束后，开始洗涤滚筒内的衣物。洗涤时间达到设定的洗涤时间 后， 通过温度传感器 21检测洗涤水的温度， 并将该温度检测值与预定的 温度阈值（如过滤组件滤膜的耐温阈值等）进行比较。
如果温度检测值大于温度阈值，则在洗涤程序中不使用循环水： 水泵 6开始工作， 第一换向阀 7切换到第一排水管路 15的方向， 第二换向阀 10将第一排水管路 15和第二排水管路 16连通， 洗涤水通过水泵 6的作 用， 将洗涤水排出， 洗涤结束， 继续进行后续的漂洗、 脱水等处理。
如果温度检测值小于或等于温度阈值，则通过浊度传感器 5检测洗涤 水的浊度， 并将该浊度检测值与预定的浊度阈值进行比较。 如果浊度检测值大于或等于浊度阈值， 则在洗涤程序中不使用循环 水： 水泵 6开始工作， 第一换向阀 7切换到第一排水管路 15的方向， 第 二换向阀 10将第一排水管路 15和第二排水管路 16连通， 洗涤水通过水 泵 6的作用， 将洗涤水排出， 洗涤结束， 继续进行后续的漂洗、 脱水等处 理。
如果浊度检测值小于浊度阈值，则在洗涤程序中使用循环水，如进行 循环洗涤： 水泵 6开始工作， 第一换向阀 7切换到过滤管路 13的方向， 第二换向阀 10将清洗管路 17截流， 洗涤水通过水泵 6的作用， 经过过滤 组件 9 的过滤， 将洗涤水中的线屑及大分子颗粒去除掉， 再经回流管路 18 回流到洗涤滚筒内继续参与洗涤。 循环时间达到设定的时间或浊度传 感器 5检测到浊度达到设定值后， 洗涤结束，继续进行后续的喷淋脱水等 处理。
如果在先洗衣程序中包括循环洗涤，则在甩干程序中使用循环水，如 进行喷淋脱水处理： 进水阀 1打开进入少量水， 滚筒 3高速旋转， 第一换 向阀 7切换到循环管路 14， 水泵工作， 滚筒高速旋转甩出的水经过送水 管路 12、 循环管路 14、 喷淋头 11， 回流到洗涤滚筒内， 回流水经过滚筒 的高速离心作用，将衣服中残留的洗衣粉去除， 以降低洗涤衣物的残留碱 度， 循环一定时间后， 第一换向阀 7切换到第一排水管路 15， 第二换向 阀 10依然保持第一排水管路 15和第二排水管路 16连通， 将喷淋废水排 出。 此过程可重复多次， 以达到理想的碱度要求。 至少一次的喷淋循环结 束后， 滚筒还可继续高速旋转， 泵继续工作， 将剩余的水排掉。
可选的，可在循环洗涤结束后或者循环洗涤的过程中自动进行过滤组 件的清洗。 例如， 可在过滤组件上设置第一压力传感器 19和第二压力传 感器 20， 通过第一压力传感器 19检测滤膜进口端的压力， 通过第二压传 感器 20检测滤膜出口端的压力， 若在循环洗涤的过程中， 两压力传感器 检测到的压力差值大于设定预设阈值时， 开始执行过滤组件的清洗过程。 清洗的方式分为： 先气洗再用水冲洗或者气水混合的方式。 流程如下（以 先气洗后水洗为例）： 水泵 6停止工作， 第一换向阀 7切换到排水管路的 方向， 将过滤管路截流， 第二换向阀 10将清洗管路和第二排水管路 16 连通， 气泵 8开始工作， 达到设定时间后， 气泵 8停止工作， 第一换向阀 7切换到过滤管路， 水泵 6工作， 利用洗涤水将过滤组件 9内被气泵振动 下来的污物经清洗管路 17、 第二排水管路 16排至洗衣机外。
采用上述洗衣流程进行洗衣控制，可避免因温度过高的洗衣用水经过 滤组件过滤处理的过程中对过滤组件造成损坏， 有利于提高衣物洗净度， 降低衣物碱度残留， 延长过滤组件的使用寿命。 此外， 过滤组件的清洗可 及时清理过滤组件的滤膜上拦截的污物，避免了因污物的长期残留造成过 滤组件清洗困难，有利于延长过滤组件的使用寿命， 降低洗衣机的维护成 本。
