以图 1中的洗涤剂投放组件为例,进液口数量为三个,分别为与洗涤剂腔室 11连通 的进液口 22, 与洗涤剂腔室 12连通的进液口 23和与洗涤剂腔室 13连通的进液口 24。
投放泵 30具有吸入口 31和排出口 32。 吸入口 31与转向阀 20的出液口 21通过管 路相连通。
在使用中, 转向阀 20可以根据指令控制出液口 21与选定的进液口相连通, 而此时 其余的多个进液口则与出液口 21处于断开状态。 在本发明的一些具体实施例中, 转向 阀 20可以根据指令控制出液口 21每次与一个选定的进液口相连通,而此时其余的多个 进液口则与出液口 21处于断开状态, 即只有一种选定的洗涤剂的腔室能够与出液口 21 相连通, 以投放一种洗涤剂。 当然, 在其他一些实施例中, 转向阀 20可以根据指令控 制出液口 21与若干选定的进液口相连通, 以同时投放多种洗涤剂。
当投放泵 30启动后通过,投放泵 30的抽吸使选定的洗涤剂从对应的洗涤剂腔室内 被泵送至投放泵 30的排出口。
例如,需要向待洗衣物中加入洗衣液时,转向阀 20控制出液口 21仅与进液口 22相 连通。
当需要投放不同的洗涤剂时,转向泵 20仅需根据指令控制出液口 21与对应的一个 进液口相连通,同时保证出液口 21与其余进液口断开即可实现利用一个投放泵 30完成 多种洗涤剂的投放。
此处的 "选定的" 可以理解为程序根据洗涤需要而选择的某几种或某一种洗涤剂, 涉及到进液口, 则是特指与程序选定的洗涤剂相对应的一个进液口, 因此"选定的 "可 以是指任意一种或几种洗涤剂、 洗涤剂腔室或进液口。
由此, 根据本发明实施例的洗涤剂投放组件, 通过转向阀 20在出液口 21与不同进 液口之间的切换, 实现了利用一个投放泵 30投放多种洗涤剂的目的, 并且本发明的洗 涤剂投放组件结构简单, 制造成本低。
在本发明实施例的洗涤剂投放组件投放一种洗涤剂后, 洗涤剂投放通道内,即转向 阀 20、 投放泵 30以及连接转向阀 20和投放泵 30的管路内会存留一些该洗涤剂,如果 下一次投放另一种洗涤剂, 则会导致两种不同的洗涤剂相互混合, 可能会造成洗涤效果 减弱,甚至会对衣物造成损坏。
为了解决上述问题, 根据本发明的一些实施例中, 如图 1所示, 洗涤剂投放组件可 以包括与水源相连通的进水阀 40。 转向阀 20上设有一个与进水阀 40相连通的进水口 25, 转向阀 20根据指令控制进水口 25与出液口 21的连通和断开。
在此可以将进水口 25视为一个进液口, 即出液口 21与进水口 25之间的连通和断 开遵循上述出液口 21与进液口之间的连通和断开的规则。具体地, 当出液口 21与进液 口中的一个连通时, 进水口 25与出液口 21断开, 而当出液口 21与进水口 25连通时, 全部的进液口则与出液口 21断开。
当进水口 25与出液口 21连通后,清水会通过投放泵 30的抽吸至洗涤剂投放通道内, 以便对洗涤剂投放通道进行清洗。 因此, 只需在相邻两次投放洗涤剂的操作中间控制转 向阀 20将出液口 21与进水口 25连通并泵送清水一次, 即可解决本发明洗涤剂投放组 件的不同种洗涤剂混合的问题。
另外, 如图 1所示, 出液口 21位于转向阀 20的上端面的中心处, 进液口 22-24和 进水口 25则围绕在出液口的四周, 例如进液口 22-24和进水口 25分布在以出液口 21 为圆心的圆周上。
下面参考图 2-4具体描述根据本发明的转向阀 20。
根据本发明实施例的转向阀 20, 包括: 阀体 210、 固定阀片 220、 转动阀片 230和 驱动器 240。
具体而言, 阀体 210上设有一个出液口 21、 多个进液口以及一个进水口 25, 并且 出液口 21、 多个进液口以及进水口 25均与阀体 210的内部相连通。
进液口的数量可以根据需要进行调整, 需要泵送几种洗涤剂就设置几个进液口。如 图 2所示, 仍以具有三个进液口的转向阀为例进行描述。 其中进液口 22为负责洗衣液 的投放, 进液口 23负责柔顺剂的投放, 而进液口 24负责消毒剂的投放。
如图 3所示, 阀体 210包括阀盖 211和位于阀盖 211下方的阀身 212。 出液口 21、 进液口 22-24和进水口 25设在阀盖 211上且与阀盖 211和阀身 212形成的阀体内部相 连通。 固定阀片 220设在阀身 212内且位于出液口 21、进液口 22-24和进水口 25的下方, 固定阀片 220的上表面面向出液口 21、 进液口 22-24和进水口 25的下端口。 固定阀片 220上设有多个与出液口 21、 进液口 22-24和进水口 25的位置——对应的通孔 221。
在阀盖 211上, 多个进液口 22-24和进水口 25围绕出液口 21分布, 并且位于以出 液口 21为圆心的圆周上。 对应地, 固定阀片 220上的通孔 221也参照出液口 21、 进液 口 22-24和进水口 25的排布在竖直方向上(即上下方向上)与出液口 21、进液口 22-24 和进水口 25分别对齐。
转动阀片 230设在阀身 212内且面向固定阀片 220的下表面,转动阀片 230上设有 连接槽 231, 除了连接槽 231对应的通孔 221外, 其余通孔 221均被转动阀片 230所密 封住。 如图 3和 4所示, 在本发明的具体实施例中, 所述转动阀片 230与所述固定阀片 220的下表面相贴合。
连接槽 231为沿上述圆周的径向延伸的长条形凹槽,并且连接槽 231的长度能够满 足将出液口 21与多个进液口 22-24中的一个或多个或进水口 25的下端口连通(如没有 必要, 建议删除) 。 另外, 连接槽 231为一封闭凹槽, 即没有延伸至转动阀片 230的边 缘而形成一端敞开的半封闭槽。
如图 4所示, 连接槽 231随着转动阀片 230的转动而转动, 当连接槽 231 的外端 233转动至一个或多个进液口或进水口 25所对应的通孔 221 的下方时, 进液口或进水 口 25与出液口 21相连通,而连接槽 231没有转到的通孔 221则被转动阀片 230密封住, 这些通孔 221所对应的进液口或进水口则与出液口 21断开。 因此, 随着转动阀片 230 的转动, 出液口 21能够在与不同的进液口或进水口相连通之间切换。
驱动器 240与转动阀片 230相连并驱动转动阀片 230相对于固定阀片 220转动, 以 使出液口 21分别与不同的进液口 22-24以及进水口 25连通。
由此, 根据本发明实施例的转向阀 20, 通过转动阀片的转动而带动连接槽 231 的 转动, 使出液口 21与进液口中的一个或多个或进水口 25相连通, 并在进液口和进水口 以及进水口 25之间进行连通切换。
根据本发明的一些示例, 转向阀还可以包括定位器 250。
如图 3所示, 定位器 250包括位于阀体 210 内的多个第一定位件 251和设在阀体 210内且与转动阀片 230随动的第二定位件 252。第一定位件 251的位置与进液口 22-24 和进水口 25的位置一一对应, 第二定位件 252转动至与一个第一定位件 251相对的位 置后, 通过第一定位件 251和第二定位件 252之间的配合, 能够确定转动阀片 230与固 定阀片 220的相对位置,即能够确定出液口 21与哪个或哪些进液口或进水口 25相连通。
第一定位件 251为磁簧开关且设在位于转动阀片 230下方的信号板 253上,而第二 定位件 252为磁铁且位于转动阀片 230的下表面上, 因此, 第一定位件 251与第二定位 件 252相对设置。 当磁铁随转动阀片 230转动至一个磁簧开关上方时, 洗衣机的控制单 元通过磁铁与磁簧开关之间的感应信号能够确定出液口 21 与哪个进液口或进水口 25 相连通, 以便对转动阀片 230进行控制。 如图 3所示, 转向阀还包括设在阀体 210和固定阀片 220之间的密封垫 260。 密封 垫 260上设有多个与出液口 21、进液口 22-24和进水口 25的位置——对应的通孔 261, 因此,密封垫 260保证了固定阀片 220与阀体 210之间除了通孔 261外其他部分的密封 性。
驱动器 240包括固定壳 241和电机 242。 固定壳 241与阀体 210相连, 具体地, 可 以位于阀身 212的下方。电机 242设在固定壳 241内且电机 242的驱动轴 243伸入阀体 210内部与转动阀片 230相连, 以驱动转动阀片 230。
为了向转动阀片 230提供可靠的驱动力,驱动器 240还可以包括与驱动轴 243相连 的驱动盘 244。 驱动盘 244与转动阀片 230相连接且彼此贴合。
优选地, 电机 241为可以沿正向和反向旋转的步进电机。通过定位器 250确定转动 阀片上的连接槽 231 的具体位置后, 洗衣机控制单元可以通过计算控制电机正传或反 转, 以在最短的时间内将出液口 21与选定的进液口或进水口 25连通, 以达到快速投放 洗涤剂的目的。 另外, 这样还能够减少电机 241的转动次数, 在节约能耗的同时延长了 电机的使用寿命。
下面描述根据本发明实施例的洗衣机。
根据本发明实施例的洗衣机包括: 洗涤剂投放组件、 洗涤桶 50和控制器。
具体而言, 在本发明的具体实施例中, 如图 1所示, 洗涤桶 50与洗涤剂投放组件 的投放泵 30的排出口 32相连通。 控制器分别与投放泵 30和洗涤剂投放组件的转向阀 20相连, 以便控制转向阀 20将出液口 21与一个选定的进液口连通, 并且控制投放泵 30将选定的洗涤剂从选定的洗涤剂腔室内泵送至洗涤桶 50内。在本发明其他一些实施 例中, 控制器分别与一个投放泵 30和洗涤剂投放组件的转向阀 20相连, 以便控制转向 阀 20将出液口 21与选定的几个进液口连通, 并且控制投放泵 30将选定的洗涤剂从选 定的洗涤剂腔室内泵送至洗涤桶 50内, 以同时投放几种洗涤剂。
优选地, 控制器还与进水阀 40相连, 在选定的洗涤剂泵送至洗涤桶 50内后, 控制 器控制转向阀 20将出液口 21与进水口 25连通, 并控制出水阀 40和投放泵 30开启以 将清水泵送至洗涤桶 50内, 在此过程中清水流经洗涤剂投放通道以将残留的洗涤剂冲 洗干净。
在使用中, 使用者可以通过按键向控制器输入程序指令, 以达到控制转向阀 20的 目的。另外, 可通过程序在每次洗涤剂投放后自动控制转向阀 20将出液口 21与进水口 25相连通以便进行洗涤剂的清洗。
由此, 根据本发明实施例的洗衣机, 通过转向阀 20在出液口 21与不同进液口之间 的切换, 实现了利用一个投放泵 30投放多种洗涤剂的目的, 并且本发明的洗衣机结构 简单, 制造成本低。
本发明实施例的洗衣机的其他构成可以是本领域技术人员已知的, 在此不再赘述。 在本说明书的描述中, 参考术语 "一个实施例" 、 "一些实施例" 、 "示意性实施 例" 、 "示例" 、 "具体示例" 、 或 "一些示例"等的描述意指结合该实施例或示例描 述的具体特征、 结构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说 明书中, 对上述术语的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具 体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结 合。
