对上述技术方案的改进： 所述的喷瀑板上安装小波轮部位为内凹的小波轮 安装座， 小波轮置于小波轮安装座内， 小波轮顶面与喷瀑板外侧基本平齐。
对上述技术方案的进一歩改进： 所述中间隔板上端与小波轮安装座底端平 齐， 中间隔板下端与內桶内侧的底面之间为所述进水口。
对上述技术方案的进一歩改进： 所述小波轮直径小于內桶底面设置的波轮 直径。
对上述技术方案的进一歩改进： 所述安装小波轮的喷瀑板数量为 2 个或 3 个， 并均布设置在內桶圆周内侧。
对上述技术方案的进一歩改进： 所述左水道与右水道高度及宽度相同， 所 述叶轮直径大于左水道或右水道的宽度。
一种波轮洗衣机， 其特征在于采用上述具有瀑布装置的洗衣机內桶。
本发明与现有技术相比具有如下优点和积极效果：
1、 本发明通过安装小波轮的喷瀑装置与内桶及其波轮的协同作用， 在洗涤 过程中， 左、 右水道中交替产生冲击水流， 小波轮周期性的顺时针、 逆时针旋 转， 在局部产生旋转水流， 实现对内桶上方衣物实现多方位、 多角度的冲刷洗 涤， 提高洗涤物的洗净率， 同时提高了洗衣效率。
2、 本发明的小波轮无需复杂的传动机构驱动， 也不需要供电。 因此， 使其 结构简单， 成本较低， 不易损坏。
3、 本发明彻底结束了波轮洗衣机自问世以来， 只有一个波轮的历史， 开创 了全新洗涤模式， 为波轮洗衣机今后的创新和进一歩发展奠定了基础。
附图说明 图 1为本实用新型一种洗衣机内桶上喷瀑装置的结构图；
图 2为本实用新型一种采用瀑布装置洗衣机內桶的洗衣机内部结构图。 具体实施方式
下面结合附图和具体实施例对本发明作进一歩详细说明。
参见图 1、 图 2， 本发明一种具有瀑布装置的洗衣机內桶的实施例， 包括內 桶 9、 內桶 9底面设置的波轮、 內桶内侧壁设置的喷瀑板 2。 喷瀑板 2与内桶 9 内侧壁之间的空间构成竖向通道， 竖向通道下端为进水口， 上端为喷瀑口 4。
在喷瀑口 4下方的喷瀑板 2上设置小波轮安装孔 7，有一小波轮 1通过一转 轴 1-1与一叶轮 1-2连为一体， 所述转轴 1-1横向置入小波轮安装孔 7内， 所 述小波轮 1位于喷瀑板 2外侧， 所述叶轮 1-2位于喷瀑板 2内侧的竖向通道内， 小波轮 1随叶轮 10-2自由转动。 喷瀑板 2上安装小波轮 1部位为内凹的小波轮 安装座 8， 小波轮 1置于小波轮安装座 8内， 小波轮 1顶面与喷瀑板 2外侧基本 平齐。
在竖向通道内在叶轮 1-2的下方竖向设置一中间隔板 5，将竖向通道下半部 分为左水道 3和右水道 6。 中间隔板 5上端与小波轮安装座 8底端平齐， 中间隔 板 5下端与內桶 9内侧的底面之间为竖向通道的进水口。
上述小波轮 1直径小于內桶 9底面设置的波轮直径，小波轮 1造型与內桶 9 底面设置的波轮基本相同。根据需要也可以单独设计小波轮 1的造型。小波轮 1 的直径与叶轮 1-2的直径相同， 所述左水道 3与右水道 6的高度及宽度相同， 所述叶轮直径大于左水道 3或右水道 6的宽度。
本实施例中安装小波轮 1的竖向通道共有两条， 并对称设置在內桶 9内侧 壁上。 根据需要， 內桶 9内侧壁上的竖向通道可以为一条， 也可以多条。
如图 2所示， 本发明一种波轮洗衣机实施例， 包括机壳、 机壳内的盛水桶、 具有瀑布装置的洗衣机內桶 9及其波轮， 本实施例波轮洗衣机采用上述实施例 了具有瀑布装置的洗衣机內桶 9的结构， 故不再赘述。 本发明工作原理： 內桶 9底部的波轮运转时， 形成压力水流， 使水从左水 道 3或右水道 6下部进水口压至水道内。 当波轮顺时针运转时， 压力水流只流 入左水道 3， 左水道 3中的水上升冲击叶轮 1-2， 使叶轮 1-2顺时针旋转， 带动 小波轮 1顺时针旋转； 当波轮逆时针运转时， 压力水流只流入右水道 6， 右水道 6中的水上升冲击叶轮 1-2，使叶轮 1-2逆时针旋转，带动小波轮 1逆时针旋转。 小波轮 1 周期性的顺时针、 逆时针运转， 在局部产生旋转水流， 实现对内桶 9 上方衣物的洗涤冲刷， 提高洗涤物的洗净比。
以上仅是本发明的一些具体实施例， 上述具体结构不能理解为是对本发明 的限制， 事实上， 本发明的具体实施例有很多种， 凡是在本发明构思内对其做 出的非实质性修改都落入本发明的保护范围之内。
