下面参考图 1-4来描述根据本发明实施例的洗涤剂投放泵组件。
根据本发明实施例的洗涤剂投放泵组件, 包括: 泵体 10、 多个活塞 20、 电机组件 40和传动机构 30、 50。 所述传动机构, 用于将多个活塞头 21与电机组件 40关联, 通 过电机组件 40控制其中一个活塞头 21在定容量腔 11内运动。
具体而言, 如图 1和 2所示, 泵体 10内设有多个容纳不同洗涤剂的定容量腔或投 放盒 11, 例如限定出三个定容量腔或投放盒 1 1以分别放置洗衣机, 柔顺剂和消毒剂。 每个定容量腔 11的端部均设有一个仅允许洗涤剂进入定容量腔 11的进液阀 12和一个 仅允许洗涤剂流出定容量腔 11的出液阀 13。 进液阀 12和出液阀 13可以采用单向阀。
多个活塞 20—一对应地设在每个定容量腔 1 1内且每个活塞 20包括活塞头 21和一 端与活塞头 21相连的活塞连杆 22。通过活塞连杆 22带动活塞头 21在定容量腔或投放 盒 11 内往复运动以便从进液阀 12处将洗涤剂吸入定容量腔 11 内, 在通过出液腔 13 将洗涤剂压出。 也就是说, 所述活塞头 21受控制往复运动, 以在定容量腔或投放盒 11 内吸进或推进定容量的洗涤剂。
具体而言, 所述活塞头 21抵接定容量腔或投放盒 11两相对侧壁面运动, 以沿运动 方向行进单位运动量或单位量的运动距离。
如图 3所示, 所述传动机构 30、 50包括多个传动件 30和多个联动组件 50, 多个 传动件 30的一端分别与对应的活塞杆 22的另一端相连以驱动活塞往复运动,多个传动 件 30的另一端上均设有连接孔 31, 部分传动件 30的连接孔 31的内周壁上沿周向设有 多个等间距设置的第一锯齿, 第一锯齿包括第一斜槽 32, 另一部分传动件 39的连接孔 31的内壁上沿周向设有多个等间距设置的第二锯齿, 第二锯齿包括第二斜槽 33。 第一 斜槽 32与第二斜槽 33均为锯齿形且锯齿形的方向相反。在本发明之较佳实施例中, 所 述活塞头 1 1沿运动方向的单位运动量与所述传动件 30内周壁上沿周向等间距设置的锯 齿关联。 也就是说, 传动件 30运动一个锯齿或锯齿运动一固定单位距离, 所述活塞头 21在定容量腔 11内也运动单位运动量, 这样洗涤剂的投放量可以做到精确控制。
在本发明之较佳实施例中, 所述电机组件 40包括一个电机, 所述一个电机通过传 动机构 (30、 50 ) 可控制多个活塞头 21运动。 在本发明之一较佳实施例中, 所述电机 或电机组件控制其中一个活塞运动, 同时控制另一个活塞不作动。
电机 40可以正反两方向旋转,并且电机 40的输出轴 41依次穿过多个传动件 30的 连接孔 31, 即多个连接孔 31沿输出轴 41的轴向方向间隔套接在输出轴 41上。
多个联动组件 50分别设在输出轴 41上, 并且分别位于输出轴 41与每个传动件 30 的连接孔 31对应的位置, 以保证每个连接孔 31至少与一个联动组件 50相配合。 当连 接孔 31套接在输出轴 41上后, 联动组件 50位于输出轴 41和连接孔 31之间。
在电机 40正转 (例如顺时针转动) 时, 联动组件 50与第一斜槽 32相卡合以带动 具有第一斜槽 32的传动件 30转动, 从而驱动对应的活塞 20做往复运动, 并且联动组 件 50在输出轴 41和具有第二斜槽 33的传动件 30之间不形成卡合, 因此形成空转, 从 而不会驱动该部分活塞 20运动。
在电机 39反转 (例如逆时针转动) 时, 联动组件 50与第二斜槽 33相卡合以带动 具有第二斜槽 33的传动件 30转动, 从而驱动对应的活塞 20做往复运动, 并且联动组 件 50在输出轴 41和具有第一斜槽 32的传动件 30之间不会形成卡合, 因此形成空转, 从而不会驱动该部分活塞 20运动。
例如, 装有洗衣剂和消毒剂的定容量腔 11所对应的传动件 30采用第一斜槽 32, 而装有柔顺剂的定容量腔 11所对应的传动件 30采用第二斜槽 33,则在电机 40正转时, 本发明实施例的洗涤剂投放泵组件同时投放洗衣剂和消毒剂, 在电机 40反转时, 则投 放柔顺剂。
本发明实施例的洗涤剂投放泵组件投放洗涤剂的种类和洗涤剂投放的组合方式均 可以通过调整洗涤剂投放泵组件的结构进行调整。
由此, 根据本发明实施例的洗涤剂投放泵组件, 通过联动组件 50与第一或第二斜 槽 32、 33的配合, 能够在电机 40正、 反转时分别驱动不同的活塞 40运动, 从而避免 了安装多个动力源, 通过一个动力源实现了分别控制不同洗涤剂投放的目的, 这样不仅 能够保证洗涤剂投放控制的灵活可靠, 而且使洗涤剂投放泵组件的结构紧凑, 有效降低 了制造成本。
根据本发明的一些实施例, 泵体 10内限定有两个分别容纳洗衣剂和柔顺剂的定容 量腔 11。
对每个传动件 30而言, 输出轴 41在对应的位置上设有至少一个与连接孔 31相配 合的联动件 50。 当与每个传动件 30相配合的联动件 50超过一个时, 该多个联动组件 50在输出轴 41 的对应位置处沿输出轴 41轴向分布, 以增加输出轴 41带动传动件 30 的传动力。 本实施例以每个传动件 30对应一个联动组件 50为例进行说明。
如图 4所示, 联动组件 50包括联动片 51和弹性件 52。 弹性件 52向第一或第二斜 槽 32、33方向常推联动片 51,以使联动片 51与第一或第二斜槽 32、33的平直端面 321、 331和竖直端面 322、 332相接触。
联动片 51的一端可枢转地设在输出轴 41上, 由于弹性件 52的推动而使联动片 51 的一端绕着枢转点转动, 导致联动片 51的另一端伸入第一或第二斜槽 32、 33内并与其 平直端面 321、 331和竖直端面 322、 332相接触。
图 4中位于左侧的联动片 51的另一端与第一斜槽 32的竖直端面 322相卡接,并且 由于弹性件 52的常推以保持这种卡接, 因此, 在电机 40正转时, 联动片 51的另一端 通过该卡接带动传动件 30随输出轴 40—起正转以驱动洗衣剂定容量腔内的活塞,而此 时右侧的联动片 51的另一端由于在正转方向上无法与第二斜槽 33的竖直端面 332相卡 接, 仅因为弹性件 52的推力而进行上下起伏运动, 无法形成联动, 因此, 右侧的输出 轴 41与传动件 30之间仅为空转, 无法投放柔顺剂。
同样地, 当电机 40反转时, 图 4中右侧的联动片 51的另一端能够与第二斜槽 33 的竖直端面 332形成卡接,进而通过该卡接带动传动件 30随输出轴 40—起反转以驱动 柔顺剂定容量腔内的活塞, 而此时左侧的输出轴 41与传动件 30之间为空转, 无法投放
洗衣剂。
优选地, 弹性件为簧片。 通过采用簧片不仅降低了制造成本, 而且不会使联动组件 50占用过大空间。
在输出轴 41上可以设有容纳联动组件 50的凹槽 42, 以方便联动组件 50的安装以 及提高了联动组件 50安装的牢固性。
传动件 30可以采用一切能够将电机 40的转动转化为推动活塞杆 22往复运动的机 构, 例如凸轮传动件。
下面来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: 洗涤剂投放泵组件。洗涤剂投放泵组件的进液阀 12分别与洗衣机内不同的洗涤剂源相连, 通过活塞 20的运动将洗涤剂抽吸到对应的定 容量腔 1 1内。 再通过活塞 20将洗涤剂从出液阀 13挤压出, 投放到洗衣桶内。
由此, 本发明实施例的洗衣机, 通过洗涤剂投放泵组件能够自由选择投放洗涤剂的 种类, 并且操作简单可靠。 另外, 本发明实施例的洗衣机结构简单, 且制造成本低。
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。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
