波轮洗衣机
技术领域
本发明涉及电器领域， 尤其是涉及一种波轮洗衣机。 背景技术
传统的波轮洗衣机主要依靠波轮的正反转来驱动水流的顺时针和逆时针水平旋转， 从而达到洗净衣物的效果， 然而， 该种洗涤方式的水流状态单一， 且周期性正反旋转的 水流使得衣物在洗涤过程中很容易缠绕在一起， 造成洗净能力下降， 同时也容易磨损衣 物。 发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。

根据本发明的波轮洗衣机， 在轴流叶轮的作用下， 内桶中的水流可以在上下方向上 流动， 从而衣物不易缠绕在一起， 有效地防止了衣物在洗涤过程中出现缠绕的现象， 从 而提高了衣物的洗涤效果以及洗衣机的洗净能力， 且降低了衣物的磨损。
具体地， 所述隔离板上形成有多个贯穿的进水孔和出水孔， 所述多个进水孔形成在 隔离板的底壁上；所述轴流叶轮可转动地设在所述外桶和所述隔离板之间且位于所述多 个进水孔的下方。
可选地， 所述轴流叶轮水平地设在所述外桶和所述隔离板之间。 由此， 通过轴流叶 轮提供沿竖直方向向上的冲击水流， 从而可以加强水流对衣物的冲散效果。
进一步地， 在所述外桶的底部设有电机， 所述电机具有输出轴， 所述输出轴穿过所 述外桶以与所述轴流叶轮相连。 由此， 通过将电机同时与内桶和轴流叶轮相连， 从而电 机可以控制内桶与轴流叶轮各自的旋转方向和旋转时间。
进一步地， 所述桶体组件进一步包括： 导流圈， 所述导流圈设在所述内桶的底部且 环绕所述轴流叶轮。 由此， 通过设置具有聚集作用的导流圈， 从而水流可以汇集并流向 轴流叶轮。
作为优选， 在所述内桶的内周壁上设置多条提供洗衣机水平旋转洗涤水流的搅拌 筋。 进一步地， 所述多条搅拌筋彼此间隔开地设在所述内桶的内周壁上。 由此， 使得衣 物的洗净效果更好。 可选地， 每条所述搅拌筋倾斜地设在所述内桶的内周壁上。 由此， 在内桶带动搅拌 筋旋转的过程中更加容易产生螺旋形的水流， 强化洗涤效果。
具体地， 所述多个出水孔包括： 多个第一出水孔， 所述多个第一出水孔形成在所述 内桶的侧壁上； 和多个第二出水孔， 所述多个第二出水孔形成在所述隔离板上且位于所 述多个进水孔的外侧。

如图 1-图 3所示， 根据本发明实施例的用于洗衣机的桶体组件 100， 包括外桶 1， 内桶 2， 轴流叶轮 3以及隔离板 7， 所述隔离板 7设置于轴流叶轮 3上方以在隔离板 7 上方界定出容纳待洗物品的容纳空间，以及在隔离板 7下方界定出轴流叶轮 3的操作空 间 42。 其中， 内桶 2设在外桶 1内， 且内桶 2的外壁面和外桶 1的内壁面彼此间隔开。 例如在图 2和图 3的示例中， 外桶 1和内桶 2大体为圆桶形， 外桶 1和内桶 2的顶部均 敞开， 内桶 2的周向尺寸小于外桶 1的周向尺寸， 且内桶 2的高度小于外桶 1的高度， 装配时， 可以将内桶 2 自上向下地放入外桶 1 内， 可选地， 内桶 2的上端面与外桶 1 的上端面相平齐， 且内桶 2的中心轴线与外桶 1的中心轴线重合， 其中， 内桶 2的外周 壁与外桶 1的内周壁共同限定出第一容纳空间 41， 第一容纳空间 41的横截面形状大致 为圆环形。 隔离板 7的底面与外桶 1的底面共同限定出轴流叶轮 3的操作空间 42， 轴 流叶轮 3的操作空间 42大体为圆柱形， 操作空间 42与第一容纳空间 41相连通。这里， 需要说明的是， 外桶 1的上端通过第一连接结构连接在洗衣机的外壳上 （图未示出） ， 内桶 2的上端通过第二连接结构可转动地连接在洗衣机的外壳上 （图未示出） ， 其中， 第一连接结构和第二连接结构的结构等对于本领域的技术人员而言是已知的，这里不再 详细说明。 另外， 需要说明的是， 方向"内"可以理解为朝向内桶 2中心的方向， 其相反 方向被定义为"外"， 即远离内桶 2中心的方向。
进一步地， 隔离板 7上形成有多个贯穿的进水孔 21和出水孔 22， 多个进水孔 21 形成在隔离板 Ί上，轴流叶轮 3可转动地设在外桶 1和隔离板 Ί之间且位于多个进水孔 21的下方。 可选地， 轴流叶轮 3水平地设在外桶 1和所述隔离板 7之间。
参照图 3， 轴流叶轮 3水平地安装在操作空间 42内， 进水孔 21和出水孔 22均形成 在隔离板 7上， 这样， 隔离板就可以通过进水孔 21和出水孔 22与第一容纳空间 41和 操作空间 42相连通， 进一步地， 轴流叶轮 3邻近隔离板 7的底面设置， 从而操作空间 42内的位于轴流叶轮 3下方的水会在轴流叶轮 3的作用下向上运动， 并通过隔离板 7 的进水孔 21 自下向上地进入内桶 2内， 将洗涤中缠绕在一起的衣物 （图未示出） 等冲 散， 接着内桶 2内的水再通过内桶 2及隔离板 7的多个出水孔 22排出至内桶 2和外桶 1之间， 然后聚集到轴流叶轮 3的下方的水继续在轴流叶轮 3的抽吸作用下向上运动， 如此循环， 洗衣机内会形成在竖直面内循环的水流， 从而可以冲散衣物， 且通过持续的 水流循环，强化了衣物的洗净效果。另外， 由于轴流叶轮 3通过隔离板 7与衣物隔离开， 从而避免了轴流叶轮 3与衣物直接接触而产生摩擦， 解决了衣物磨损的问题。 优选地， 轴流叶轮 3具有五个叶片。
根据本发明实施例的用于洗衣机的桶体组件 100， 通过将轴流叶轮 3设置在隔离板 7的下方， 在轴流叶轮 3的作用下， 内桶 2中的水流可以在上下方向上循环流动， 从而 衣物不易缠绕在一起， 有效地防止了衣物在洗涤过程中出现缠绕的现象， 从而提高了衣 物的洗涤效果以及洗衣机的洗净能力， 且降低了衣物的磨损。
在本发明的一个实施例中， 如图 3和图 4所示， 在外桶 1的底部设有电机 5， 电机 5具有输出轴 51， 输出轴 51穿过外桶 1以与轴流叶轮 3相连。
参照图 3和图 4， 电机 5设在外桶 1外且位于外桶 1的底部， 例如电机 5可以固定 在外桶 1的下表面上， 电机 5上连接有竖直向上延伸的输出轴 51， 输出轴 51与轴流叶 轮 3相连， 以驱动轴流叶轮 3转动， 进一步地， 电机 5与隔离板 7相连， 这样电机 5 可以驱动内桶 2转动， 通过将电机 5 同时与隔离板 7和轴流叶轮 3相连， 从而电机 5 可以控制内桶 2与轴流叶轮 3各自的旋转方向和旋转时间， 例如， 电机 5可以仅驱动内 桶 2顺时针或逆时针旋转， 或者仅驱动轴流叶轮 3顺时针或逆时针旋转， 或者同时驱动 内桶 2和轴流叶轮 3同向或反向旋转。需要理解的是， 内桶 2与轴流叶轮 3在洗涤中的 旋转顺序、旋转方向以及旋转时间的组合方式可以根据实际需求设置， 以更好地满足实 际要求。 这里， 需要说明的是， 在洗衣机的工作过程中， 轴流叶轮 3通常以固定方向旋 转， 该旋转方向保证轴流叶轮 3可以将轴流叶轮 3下方的水抽吸到轴流叶轮 3的上方。
进一步地， 电机 5的输出轴 51暴露在水中的部分设有水封结构， 以防止水进入， 从而影响电机 5的正常工作。 例如在图 3的示例中， 水封结构可以是防水轴套 52， 可 选地，防水轴套 52的内表面形成为与电机 5的输出轴 51的外表面的形状相适配的形状。
进一步地， 桶体组件 100进一步包括： 导流圈 6， 导流圈 6设在隔离板 7的底部且 环绕轴流叶轮 3。 例如在图 3的示例中， 导流圈 6的形状大体为圆环形， 导流圈 6设在 隔离板 7和外桶 1之间， 且位于隔离板 7的底部， 具体地， 导流圈 6的上端与隔离板 7 相连， 且导流圈 6的下端向下延伸， 轴流叶轮 3位于导流圈 6内。 由此， 通过设置具有 聚集作用的导流圈 6， 从而水流可以汇集并流向轴流叶轮 3。
可选地， 导流圈 6被构造成从下到上导流圈 6的横截面积先逐渐减小、 再相等。 参 照图 3， 导流圈 6的侧壁的横截面形状大致为 J形， 具体地， 导流圈 6在从上到下的方 向上先竖直向下延伸、再沿内桶 2的径向向外弯曲延伸， 此时导流圈 6下部的周向尺寸 大于导流圈 6上部的周向尺寸， 从而导流圈 6可以更加充分地将水流聚集至轴流叶轮 3 处。
或者可选地， 导流圈 6的侧壁的横截面形状为 U形 （图未示出） ， 以具有更好的聚 集效果。
如图 1-图 3所示， 桶体组件 100进一步包括： 多条搅拌筋 23， 多条搅拌筋 23彼此 间隔开地设在内桶 2的内周壁上。 可选地， 搅拌筋 23为三条， 且三条搅拌筋 23均匀地 分布在内桶 2的周向上。
例如在图 1、 图 2和图 3的示例中， 内桶 2的内周壁上设有三条搅拌筋 23， 每条搅 拌筋 23从内桶 2的下部向上延伸， 搅拌筋 23可以固定在内桶 2上， 这样搅拌筋 23可 以随着内桶 2的转动而绕着内桶 2的中心轴线旋转，从而可以充分地搅拌洗涤中的衣物， 使得衣物的洗净效果更好， 进一步地， 三条搅拌筋 23在内桶 2的周向上均匀分布， 也 就是说， 任意相邻的两条搅拌筋 23之间相互间隔开的距离大致相等。 可选地， 每条搅 拌筋 23倾斜地设在所述内桶 2的内周壁上，通过将搅拌筋 23设置成与垂直方向呈一定 角度， 从而在内桶 2带动搅拌筋 23旋转的过程中更加容易产生螺旋形的水流， 强化洗 涤效果。 需要理解的是， 搅拌筋 23的数量可以根据实际要求设置， 以更好地满足实际 要求。
这样， 设有搅拌筋 23的内桶 2在旋转时可以形成在水平面旋转的水流， 轴流叶轮 3 在旋转时可以形成在竖直面循环的水流，从而可以实现水平和竖直方向上全面的水流洗 涤效果， 进一步避免了衣物缠绕的问题， 且增强了衣物的洗净效果。
可选地， 多个进水孔 21均匀地分布在隔离板 7上。 参照图 1， 每个进水孔 21的形 状相同、 大小相等， 进水孔 21可以多排多列呈放射状地分布在内桶 2的底壁上， 每圈 进水孔 21可以形成为与内桶 2同心的圆环，多圈进水孔 21沿内桶 2的径向从内向外依 次布置。 需要理解的是， 进水孔 21的数量、 尺寸以及在内桶 2上的布置方式可以根据 实际要求设置， 以更好地满足实际要求。
进一步地， 如图 2-图 4所示， 多个出水孔 22包括： 多个第一出水孔 221和多个第 二出水孔 222。其中，多个第一出水孔 221形成在内桶 2的侧壁上，多个第二出水孔 222 形成在内桶 2的底壁上， 且多个第二出水孔 222位于多个进水孔 21的外侧。 例如在图 5的示例中， 内桶 2内部的水可以通过内桶 2侧壁的第一出水孔 221向外流入第一容纳 空间 41， 也可以通过内桶 2底壁的第二出水孔 222向下流入操作空间 42。
可选地， 多个第一出水孔 221多排多列地分布在内桶 2的侧壁上。 例如在图 2的示 例中， 多个第一出水孔 221形成在内桶 2的侧壁上， 每列第一出水孔 221均沿内桶 2 的轴向延伸， 每排第一出水孔 221水平地环绕在内桶 2的内壁上， 其中每列相邻的两个 第一出水孔 221之间的距离小于每排相邻的两个第一出水孔 221之间的距离。
可选地， 多个第二出水孔 222邻近内桶 2的底壁的边沿布置。 如图 2所示， 隔离板 7的外边缘处形成有多个第二出水孔 222， 第二出水孔 222位于导流圈 6的外部， 每个 第二出水孔 222的形状相同、 大小相等， 第二出水孔 222多排多列呈放射状分布， 每圈 第二出水孔 222可以形成为与内桶 2同心的圆环，多圈第二出水孔 222沿内桶 2的径向 向外布置。
可选地， 每个进水孔 21和每个出水孔 22的形状为圆形、 椭圆形、 长圆形或多边形 等。 需要理解的是， 进水孔 21和出水孔 22的形状可以根据实际要求设置， 以更好地满 足实际要求。
