Description

一种内桶波轮一体结构及洗衣机及洗涤方法 技术领域
本发明涉及洗衣机领域， 尤其是一种内桶波轮一体结构及应用该结构的洗衣机及洗衣 机的洗涤方法。 背景技术
现有技术， 通常将洗衣机分为滚筒说洗衣机、 波轮洗衣机和搅拌式洗衣机。 从原理上讲， 波轮洗衣机和搅拌洗衣机是极其相似的。 波轮洗衣机 (pulsator washing machine)依靠波 轮搅动水流， 而无规则运动的水流搅动衣物， 从而完成衣物的洗涤漂洗过程； 搅拌洗衣机 (agitator washing machine)依靠搅拌立杆， 直接书或者借助于水力拖动衣物在水中运动， 从而完成衣物的洗涤。 滚筒洗衣机（drum washing machine)依靠固定于内筒内壁的数个凸 肋提升衣物， 衣物在滚筒中反复提升、 跌落完成洗涤漂洗过程。 现有技术认为， 滚筒式洗衣机洗涤用水少、 衣物磨损率很低、 衣物不缠绕、 可设热水 装置， 容易实现自动化， 但洗涤力弱、 洗涤时间长、 结构复杂、 体积庞大、 耗费金属原料 多、 成本较高。 高速甩干时平衡相对较难控制。 搅拌式洗衣机洗涤均匀性好、 洗涤力强、 对衣物磨损小、 洗涤容量大、 但洗涤时间长、 噪音大、 搅拌翼的回转机构复杂、 加工困难、 成本较高、 体积大。 波轮式洗衣机结构简单、 洗涤力强、 洗涤时间短、 成本低、 重量轻， 但衣物磨损率及缠绕率都较高， 洗涤均匀性较差， 用水量较多。 目前洗衣机已经广泛在家庭中使用， 但是现有的洗衣机多为双动力或者双筒机， 结构 比较复杂且尺寸较大， 占用家庭较大空间。 一般的波轮洗衣机内桶中设置波轮， 结构相对 复杂， 安装工艺繁琐， 成本高， 若能将内桶和波轮设为一体结构复杂程度、 安装工艺和成 本将大大的降低。 如何能将上述各种洗衣机的优点集为一体是面临的一项重大问题。
专利号 CN200510094191. 3的中国专利公开了一种洗涤效果好、 成本低、 无环境污染的 衣物的洗涤方式， 主要包括如下步骤： （一）往盛放有待洗衣物的洗衣机内加注适量的洗涤 水和消泡剂； （二)通过控制装置控制洗衣机内胆的转速为 3〜12rpm， 并且内胆运转时正转 与反转相互间隔进行， 且每次正转的圈数为 0. 3〜1. 5圈， 每次反转的圈数为 0. 3〜1. 5圈； 这样连续运转 0. 4〜1. 5分钟后， 再停止运转 0. 3〜1. 5分钟； （三） 重复步骤 (二）中的程序 3〜20次； （四）然后使内胆单向转动， 进行均布程序， 均布结束后转笼中速脱水 0. 3〜3. 5 分钟； （五)重复步骤 (一)至（四）中的程序 2〜12次， 就完成了一个洗涤过程。 但是滚筒的 形式仍然存在高速甩干时平衡相对较难控制的问题。 专利号 CN03276136. 8的中国专利公开了一种除污垢好、 缠绕和磨损又低的洗衣机。 螺 旋式洗衣机既提高了洗净比、 洗涤均匀度， 又降低了缠绕率、 磨损率。 但洗衣机的结构却 简单， 波轮（内桶底）与内桶壁连成一体， 无离合器， 内桶上布满来复线式的螺纹。 在内桶 的正转、 停、 反转过程中， 通过有压力多方向的揉搓、 无副作用的离心力洗、 空化作用、 高速启动的惯性等综合作用， 将衣物洗干净。 但是上述专利中涉及的洗衣机仅对内桶壁增 加螺旋结构， 内桶底结构未给定义， 内桶底空间浪费， 无法对衣物起到洗涤作用。
专利号 CN00215731. 4 的专利公开了无波轮全自动洗衣机，包括内桶、 外桶、 内桶底拨 水筋和电机，其特点是内桶与内桶底的拨水筋为一体，内桶底拨水筋代替现有波轮洗衣机的 波轮。 电机转子固定在内桶主轴上，电机转子与内桶共同使用内桶主轴。 由于内桶与内桶底 的拨水筋为一体，所以电机带动内桶正反向间歇运转时，内桶底的拨水筋带动水流运动，起 到波轮的作用。 上述专利公开无波轮结构， 其未具体对内桶底及侧面结构进行说明， 其图 示内桶底结构对衣物的翻转无加强作用， 侧面也没有对应的拨水叶对内部洗涤水进行搅动 处理。 鉴于此提出本发明。 发明内容 本发明的目的为克服现有技术的不足， 提供一种内桶波轮一体结构， 并在内桶底增加 拨水叶结构， 该结构从内桶底延伸至内桶壁既能够使衣物在圆周方向上有提升跌落被击打 的运动， 还能使衣物在径向翻转， 全方位均匀洗涤衣物， 洗涤效果好， 使衣物仅通过一个 洗涤桶即可完成洗涤漂洗及脱水过程， 使洗衣机结构简单， 简化安装工艺并降低成本。 本发明的另一目的为提供一种具有上述内桶波轮一体结构的洗衣机。 本发明的另一目的为提供一种上述洗衣机的洗涤方法， 该方法间隔正反转， 减少缠绕， 且每次正转角度不等于反转角度， 以避免衣物在同一位置不断洗涤摩擦， 造成洗涤不均， 借助波轮内桶一体结构洗涤中提升摔打、 离心力翻转、 撞击击打、 摩擦揉搓共同作用使衣 物得到全方位均匀洗涤。 为了实现该目的， 本发明采用如下技术方案： 一种内桶波轮一体结构， 该结构包括一竖直使用的内桶和内桶底的拨水叶， 所述的拨 水叶与内桶底一体设置， 所述拨水叶为设置在内桶底的凸起结构， 拨水叶至少为两个， 每 个拨水叶由内桶底中心延伸至内桶壁， 且每个拨水叶沿内桶底径向向外方向升高延伸， 延 伸至最高点后与内桶壁连接， 沿圆周方向由一侧以缓坡形状升高延伸至最高点后以陡坡形 状降回到内桶底。 所述的拨水叶为 2〜4个， 多个拨水叶沿内桶底圆周顺时针或逆时针呈辐射状绕内桶轴 心均匀分布， 且沿内桶底圆周顺时针或逆时针相同方向升高延伸。 所述拨水叶的缓坡升高侧平滑升高， 所述拨水叶的陡坡下降侧平滑下降， 内桶底与缓 坡升高侧、 陡坡下降侧圆滑过渡， 所述的拨水叶沿内桶底径向向外平滑升高， 内桶壁与拨 水叶圆滑过渡。 所述的拨水叶在内桶径向不同位置处的最高点组成拨水叶的脊梁， 该脊梁由两段弧线 组成， 两段弧线的圆心分布在脊梁的不同侧， 靠近内桶中心的弧线的圆心在缓坡升高侧， 靠近内桶壁的弧线的圆心在陡坡下降侧。 所述的拨水叶在脊梁上任意一点两侧的倾斜程度不同， 缓坡升高侧的倾斜程度小于陡 坡下降侧的倾斜程度。 所述的拨水叶与内桶底的交线为弧线， 缓坡升高侧与内桶底的交线和陡坡下降侧与内 桶底的交线的弯曲方向相同， 且每条交线与内桶底的最外围圆周圆滑过渡。 所述的内桶的高度与内桶的直径的比值范围为 0.4〜2， 优选内桶的高度小于或等于内 桶的直径。 所述的内桶的高度与内桶的直径的比值为 0.6。 所述的内桶底中心位置设置有供动力轴穿入的轴孔， 所述的内桶的内桶壁和 /或内桶底 分布有多个漏水孔。 一种具有上述内桶波轮一体结构的洗衣机， 所述的洗衣机的外桶内部同轴设置上述内 桶波轮一体结构， 洗衣机的动力轴伸入内桶波轮一体结构中内桶底中心位置的轴孔中。 一种洗涤方法， 该方法通过控制洗衣机间隔正反转， 使衣物在内桶中翻转， 完成洗涤， 该方法中洗衣机每次正转、 反转的角度不同， 每次正转的角度不等于每次反转的角度， 借 助波轮内桶一体结构， 在圆周方向正转时使衣物被拉高后接近垂直跌落， 反转时使衣物在 圆周方向被接近垂直的面撞击， 同时正反转过程中， 在径向旋转产生的离心力和内桶底结 构的引导下， 衣物向外向上翻转， 到达内桶壁后向内向下翻转。 所述的衣物在圆周方向正转时的拉高后跌落摔打或反转时的撞击击打与在径向方向的 翻转同时进行， 使衣物在内桶内一直处在连续翻滚状态， 同时与内桶底和内桶壁发生碰撞 和摩擦， 均匀洗涤。 所述的圆周方向和径向衣物的运动由内桶底的凸起结构引导。 所述的凸起结构为至少两个， 优选 2〜4个， 多个凸起结构沿内桶底圆周顺时针或逆时 针绕内桶轴心均匀分布， 且沿内桶底圆周顺时针或逆时针相同方向升高延伸， 该凸起结构 沿内桶底径向向外方向升高延伸， 延伸至最高点后与内桶壁连接， 沿圆周方向由一侧以缓 坡形状升高延伸至最高点后以陡坡形状降回到内桶底。 洗涤过程中在圆周方向上， 正转时衣物沿凸起结构平滑升高延伸面升高至最高点后沿 接近垂直的陡坡面跌落摔打， 反转时衣物撞击到接近垂直的陡坡面上。 洗涤过程中在桶径方向上， 旋转产生的离心力使衣物沿凸起结构向外向上翻转， 至内 桶壁后向内向下翻转。 所述的洗涤方法中洗涤或漂洗过程中， 内桶以一定的加速度升至正转转速 X， 正向转 动一定时间 Tl，暂停一段时间，然后以一定加速度升至反转转速 Υ，反向转动一定时间 Τ2， 每次正转角度不等于反转角度， 每次洗涤或漂洗重复该过程 5〜500次。 所述的正转转速 X和反转转速 Υ分别为 20〜 1 OOrpm, 所述的正转的时间 T 1和反转的 时间 T2分别为 l〜5s， 且 ΧχΤ1≠ΥχΤ2。 所述的洗涤方法包括如下步骤：

2、本发明中在内桶底增加拨水叶结构， 该结构从内桶底中心延伸至内桶壁既能够使衣物 在圆周方向上有提升跌落被击打的运动， 还能使衣物在径向翻转， 全方位均匀洗涤衣物， 洗 涤效果好。
3、本发明中内桶底的拨水叶圆周方向逐渐上升急速下降， 使正转时有将衣物提升后摔打 的功效， 反转使有撞击衣物的功效； 内桶中心到内桶壁方向逐渐升高， 且最高点处与内桶壁 连接， 由使衣物在径向有向上向外翻转至内桶壁后向下向内翻转的功效。
4、 内桶高度较小， 节省安装空间。
5、 本发明所述洗涤方法正中转反转间隔设置， 减少衣物缠绕。

图 9、 本发明所述洗涤方法中正转时周向衣物的运动轨迹图 图 10、 本发明所述洗涤方法中反转时周向衣物的运动轨迹图 其中： 1、 内桶， 11、 内桶底， 12、 内桶壁， 2、 拨水叶， 21缓坡升高侧， 22陡坡下降 侧， 23、 脊梁， 3、 加强筋， 4轴孔， 5、 漏水孔， 6、 外桶， 7、 动力轴。 具体实施方式 如图 1所示， 本发明所述一种内桶波轮一体结构， 该结构包括一竖直使用的内桶 1和 内桶底 11的拨水叶 2， 所述的拨水叶 2与内桶 1一体设置， 所述拨水叶 2为设置在内桶底 11的凸起结构， 拨水叶 2至少为两个， 每个拨水叶 2沿内桶底 11圆周方向和桶径向外方向 分别升高延伸， 沿内桶底 11径向向外方向升高延伸至最高点后与内桶壁 12连接， 沿圆周 方向由一侧以缓坡形状升高延伸至最高点后以陡坡形状降回到内桶底。 即该拨水叶 2由内桶底 11中心延伸至内桶壁 12， 内桶底 11的拨水叶 2圆周方向缓慢 上升到最高点后急速下降， 内桶 1中心到内桶壁 12方向逐渐升高， 且最高点处与内桶壁 12 连接。
洗涤过程中在圆周方向上， 正转时衣物沿拨水叶 2平滑的缓坡升高侧 21升高至最高点 后沿接近垂直的陡坡下降侧 22跌落被摔打受到冲击力， 反转时衣物撞击到接近垂直的陡坡 下降侧 22受到冲击力。 在桶径方向上， 旋转产生的离心力和内桶底 11的拨水叶 2由内桶 中心至内桶壁的逐渐升高的趋势使衣物沿拨水叶 2向外向上翻转， 至内桶壁 12后向内向下 翻转。 衣物在圆周方向正转时的拉高后跌落摔打或反转时的撞击击打与在径向方向的翻转 同时进行， 使衣物在内桶内一直处在连续翻滚状态， 同时与桶底和桶壁发生碰撞和摩擦， 从而一直在洗涤不同的位置。 规定内桶 1沿升高延伸方向转动时为反转， 反之为正转。 优选所述的拨水叶 2为 2-4个， 多个拨水叶 2沿内桶底 11绕内桶 1的轴心均匀分布， 且沿内桶底 11圆周顺时针或逆时针相同方向升高延伸。 所述的拨水叶 2为两个时， 两个拨 水叶 2中心对称分布， 所述拨水叶为三个时， 任意两个拨水叶 2之间所成的角度为 120度， 所述的拨水叶 2为多个时， 多个拨水叶 2绕内桶 1的轴心呈辐条状均匀分布。 所述的拨水叶 2沿内桶底 11圆周顺时针或逆时针升高延伸时由低向高平滑过渡， 所述 的拨水叶 2沿桶径向外延伸方向由低向高平滑过渡， 且由低向高延伸方向的两侧之间的宽 度逐渐增大， 到内桶壁 12处的宽度最大。 所述拨水叶 2的缓坡升高侧 21平滑升高， 所述拨水叶 2的陡坡下降侧 22平滑下降， 内桶底 11与缓坡升高侧 21、 陡坡下降侧 22圆滑过渡， 所述的拨水叶 2沿内桶底 11径向向 外平滑升高， 内桶壁 12与拨水叶 2圆滑过渡。 拨水叶 2在内桶 1径向不同位置处的最高点组成拨水叶 2的脊梁 23，该脊梁 23由两段 弧线组成， 两段弧线的圆心分布在脊梁 23的不同侧， 靠近内桶轴心的弧线的圆心在缓坡升 高侧 21， 靠近内桶壁的弧线的圆心在陡坡下降侧 22。 且两段圆弧连接处平滑对接， 沿内桶 1有上向下看拨水叶 2类似 "〜" 。 拨水叶 2被脊梁 23上任意一点所在的与内桶 1同轴的圆柱面所截的截面在该点两侧的 倾斜程度不同， 缓坡升高侧 21的倾斜程度小于陡坡下降侧 22的倾斜程度。 拨水叶 2与内桶底 11的交线为弧线， 缓坡升高侧 21与内桶底 11的交线 a和陡坡下降 侧 22与内桶底 11的交线 b的弯曲方向相同， 弯曲半径不同， 缓坡升高侧 21与内桶底 11 的交线 a的弯曲半径小于陡坡下降侧 22与内桶底 11的交线 b的弯曲半径， 且交线与内桶 底 11的最外围圆周圆滑过渡。 这样的结构势必会导致由低向高延伸方向的两侧之间的宽度 逐渐增大， 到内桶壁 12处的宽度最大。 内桶 1的高度与内桶 1的直径的比值范围为 0.4〜2， 优选内桶 1的高度小于或等于内 桶 1的直径， 内桶内部洗涤部分高度小于内桶最小直径， 再优选内桶 1的高度与内桶 1的 直径的比值范围为 0.6。 这样充分利用拨水叶的对衣物的击打及离心翻滚作用。 内桶 1的内桶壁 12和 /或内桶底 11上设置有减小内桶 1变形的加强筋 3， 该加强筋 3 沿轴向和 /或周向设置在内桶 1的内桶壁 12的外表面上， 该加强筋 3沿径向和 /或周向设置 在内桶 1的内桶底 11的外表面上。 内桶壁 12外表面的加强筋 3在内桶壁 12外表面上沿轴向设置或者沿圆周方向水平设 置或者轴向、 周向交错设置； 所述的内桶底 11外表面的加强筋在内桶底 11外表面沿周向 设置或者沿径向设置或者周向、 径向交错设置。 大大增强了内桶 1的强度。 内桶底 11 中心位置设置有供动力轴穿入的轴孔 4 (参见图 4) ， 动力轴穿入该轴孔 4 带动内桶转动， 完成洗涤过程， 所述的内桶 1的内桶壁 12和 /或内桶底 11分布有多个漏水 孔 5， 以便洗涤和排水时内外水流交换。 本发明所述的一种洗涤方法， 该方法通过控制洗衣机间隔正反转， 使衣物在内桶中翻 转， 完成洗涤， 该方法中洗衣机每次正转、 反转的角度不同， 每次正转的角度不等于每次 反转的角度， 借助波轮内桶一体结构， 在圆周方向正转时使衣物被拉高后接近垂直跌落， 反转时使衣物在圆周方向被接近垂直的面撞击， 同时正反转过程中， 在径向旋转产生的离 心力和内桶底的结构引导衣物向外向上翻转， 到达内桶壁后向内向下翻转。 所述的衣物在圆周方向正转时的拉高后跌落摔打或反转时的撞击击打与在径向方向的 翻转同时进行， 使衣物在内桶内一直处在连续翻滚状态， 同时与内桶底和内桶壁发生碰撞 和摩擦， 均匀洗涤， 提高洗涤率。 所述的圆周方向和径向衣物的运动由内桶底的凸起结构引导。 所述的洗涤过程中在圆周方向上， 正转时衣物沿凸起结构平滑升高延伸面升高至最高 点后沿接近垂直的陡坡面跌落摔打， 反转时衣物撞击到接近垂直的陡坡面上。 所述的洗涤 过程中在桶径方向上， 旋转产生的离心力和内桶底的凸起结构由内桶中心至内桶壁的渐高 趋势使衣物沿凸起结构向外向上翻转， 至内桶壁后向内向下翻转。 所述的洗涤方法中洗涤或漂洗过程中， 内桶以一定的加速度升至正转转速 X， 正向转 动一定时间 Tl，暂停一段时间，然后以一定加速度升至反转转速 Υ，反向转动一定时间 Τ2， 每次正转角度不等于反转角度，重复该过程 5〜500次。每次正转角度大于或小于反转角度。 所述的正转转速 X和反转转速 Υ分别为 20〜 1 OOrpm, 所述的正转的时间 T 1和反转的 时间 T2分别为 l〜5s， 且 ΧχΤ1≠ΥχΤ2， χχΤ1>ΥχΤ2 或者 ΧχΤ1<ΥχΤ2。 所述的洗涤方法包括如下步骤：

5 ) 控制洗衣机进水， 重复步骤 2)、 3 ) 2次， 完成漂洗、 脱水。 最后一次脱水结束后控制内桶正反转， 将脱水后挤压在一起的衣物分散开， 以利于用 户进行取出晾晒。 实施例七 如图 8、 图 9、 图 10所示， 本实施例所述为衣物在内桶 1中的运动轨迹分析， 定义内 桶 1沿升高延伸方向转动时为反转， 反之为正转。 图 8为沿内桶中心线的竖直平面截内桶所得的截面， 如图所示， 由于拨水叶 2沿径向 逐渐升高的趋势， 衣物沿径向， 向外向上运动， 到达内桶壁 12后， 受到内桶壁 12的反向 作用力， 衣物开始向内向下运动。 图 9、 图 10为沿内桶 1同轴的圆柱面所截内桶的截面的展开图， 如图 9所示， 正转时 由于拨水叶 2沿圆周方向逐渐升高的趋势， 衣物沿周向逐渐被拉高， 由于拨水叶 2沿圆周 方向升高到最高点后迅速下降， 衣物被拉高后跌落， 拉高过程中衣物与内桶有摩擦， 跌落 过程中衣物受到摔打， 对衣物起到洗涤作用。 如图 10所示， 反转时， 衣物沿拨水叶 2的缓坡升高侧向下运动， 到达陡坡下降侧后衣 物撞击到陡坡下降侧受到击打， 伴随着衣物与内桶的摩擦， 对衣物起到洗涤作用。 洗涤过程中， 衣物在圆周方向正转时的拉高后跌落摔打或反转时的撞击击打与在径向 方向的翻转同时进行， 使衣物在内桶内一直处在连续翻滚状态， 同时与内桶底和内桶壁发 生碰撞和摩擦， 均匀洗涤。 以上所述仅为本发明的优选实施方式， 应当指出， 对于本领域的普通技术人员而言， 在不脱 离本发明原理前提下， 还可以做出多种变形和改进， 这也应该视为本发明的保护范围。
