Description

洗衣机及洗涤方法 技术领域
本发明涉及一种洗衣机， 特别涉及一种使用颗粒参与洗涤的洗衣机及洗涤方法， 属于洗衣机技术领域。
背景技术
传统洗衣机的洗涤方法是采用水作为洗涤介质， 向洗衣机内加入水和洗涤剂， 进行洗涤， 洗涤后利用脱水功能将洗衣机内的污水排出， 然后重新加入干净的水， 继续进行洗涤或者漂洗过程， 洗涤全部结束后再将水排出。 这种方法只是单纯地将 水排出， 再重新注入干净的洗涤水， 水消耗量非常大。 同时， 洗涤液里面还含有较 多的对环境有害的化学物质， 而且每次洗涤过程的耗费时间较长， 耗电量也较大。
针对传统洗衣机的不足， 现有技术中出现了一种采用聚合物材料特殊制作的固 体颗粒作为洗涤介质的洗涤方法， 通过固体颗粒和衣服之间的摩擦， 吸附并吸收衣 服上的污垢， 从而实现洗涤的功能。 该洗涤方法能节水 80%以上， 另外， 该固体颗粒 洗涤介质可以回收再利用， 使用寿命长， 无需更换， 安全环保。
采用该颗粒洗涤方法的洗衣机， 一般都会在洗衣机设置有颗粒的储存空间， 并 在外筒上设置进料孔和出料孔， 在洗涤前， 将颗粒从进料孔中投放至外筒内， 在洗 涤结束后， 在将颗粒完全回收到颗粒的储存空间内， 在颗粒回收时， 需要高速旋转 内筒， 利用离心力将颗粒甩至储存空间内， 如要对颗粒进行脱水， 还需要再次投放 颗粒和回收颗粒， 洗衣机的结构和洗涤过程都较为复杂， 而且不能保证颗粒 100%的 回收率。

具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述：
实施例一：
如图 1和图 2所示， 一种洗衣机， 本实施例以滚筒洗衣机为例做详细说明， 洗衣 机包括一壳体 （图中未示出）， 在壳体内设置有外筒 1、 内筒 2及作为洗涤介质的固体 颗粒 8， 其中， 外筒 1是固定不转的， 主要用于盛水， 内筒 2用于洗涤， 内筒 2设置在 外筒 1的内侧， 内筒 2的筒壁上均匀地开有若干个用于供洗涤水通过的开孔 3， 开孔 3 的孔径小于固体颗粒 6的直径， 开孔 3的形状可以为圆形、 矩形、 多边形等， 内筒 2通 过驱动装置 4驱动转动。 在外筒 1的上部设置有进水口 （图中未示出）， 用于洗涤和漂 洗过程的进水， 在外筒 1的下部设置有排水口 （图中未示出）， 用于脱水后的排水。 在洗涤时， 衣物 5放置在内筒 2中。
在内筒 2的内壁上平行设置有多个向内突出的刮板 6， 刮板 6倾斜设置在内筒 2的 筒壁上， 沿内筒 2筒壁的弧度弯曲， 刮板 6的两端点之间的连线相对于内筒 2的轴心线 具有一夹角 7， 刮板 6随着内筒 2—起旋转， 带动作为洗涤介质的固体颗粒 8沿刮板 6斜 向上或斜向下运动， 当运动到一定高度时， 颗粒 8会从刮板 6上掉落至内筒 2内实现翻 转。 刮板 6倾斜的方向可以如图 1所示斜向上倾斜， 此时， 夹角 7为锐角； 也可以斜向 下倾斜， 此时， 夹角 7为钝角。 本实施例中， 如图 1所示， 以夹角 7为锐角为例。
为了方便衣物 5与颗粒 8的分离， 沿内筒 2的内侧设置一圈隔离筒 9， 衣物 5放置在 隔离筒 8内， 隔离筒 8的底部与顶部分别与内筒 2的底部和顶部通过紧固件固定连接， 与内筒 2同步旋转。 隔离筒 9呈网状结构， 以便颗粒 8和洗涤水更容易流进或流出， 衣 物 5被隔离在隔离筒 9内， 颗粒 8则被隔离在隔离筒 9和内筒 2之间。 在洗涤时， 颗粒 8 穿过隔离筒 9与衣物 5充分混合， 颗粒 8优选采用高分子表面多孔的材料， 利用颗粒 8 较好的吸附能力， 吸附衣物 5和洗涤水中的污物， 达到较好的洗涤效果。
为了不伤及颗粒 8， 本实施例， 刮板 6的横断面优选采用流线形， 大致呈圆弧状。 颗粒 8的直径大约在 2-3mm的范围内， 所以刮板 6的高度选取大于或等于 5mm， 刮板 6的 高度略小于或等于内筒 2内壁与隔离筒 9外壁之间的距离。 刮板 6的数量为 2-10个， 优 选为 5-8个， 如图 2所示， 本实施例中刮板 6的数量为 8个， 沿内筒 2的筒壁均匀设置， 刮板 6的数量越多、 高度越大， 所能带动的颗粒 8的数量就越多， 带动颗粒 8的推进速 度也就越快， 则更有利于颗粒 8的投放和回收， 同时也有利于颗粒 8与衣物的充分混 合， 进一步提高洗净率。
与普通的滚筒洗衣机一样， 在隔离筒 9的内壁上设置有至少一个向内突出的提升 块 13， 在洗涤过程中， 衣服 5在提升块 13的作用下， 在内筒 2内不断地进行上下翻转， 提升， 然后再摔下， 循环往复达到洗涤的效果， 提升块 13的数量可选择 1-3个， 本实 施例中， 优选采用 3个提升块 13， 沿隔离筒 9的周向均匀分布。 同时， 内筒 2是交替正 反旋转的， 在内筒 2筒壁的刮板 6带动下， 颗粒 6在内筒 2内还会不断的进行沿内筒 2的 轴线前后方向上的运动及翻转， 使衣物 5与颗粒 6混合更加充分， 提高了洗净率。 在洗衣机内设置有用于储存固体颗粒 8的储存空间 10， 储存空间 10为内筒 2向一 侧延伸的延伸部，， 延伸部上与内筒 2—样， 开有仅供洗涤水通过的开孔 3， 延伸部与 内筒 2由驱动装置 4驱动同步转动， 内筒 2内壁上的刮板 6延伸至延伸部的内壁。 本实 施例中， 储存空间 9与内筒 2形状一致， 呈圆筒状， 也可以采用圆环状。 当然， 内筒 2 也可以向顶部方向延伸， 在内筒 2的顶部设置储存空间 10， 为了方便投取衣物 5， 储 存空间 10可以采用圆环状。
储存空间 10与内筒 2连通， 储存空间 10与内筒 2之间设置一用地阻挡衣物 5的挡板 11， 挡板 11设置于内筒 2径向的中心位置， 可通过多个连接板 （图中未示出） 与内壁 2的筒壁固定连接， 挡板 11周圈与内筒 2的内壁之间具有用于将储存空间 10与内筒 2相 互连通的通道 12， 挡板 11阻挡衣物 5不能进入储存空间 10， 颗粒 8则通过该通道 12进 出储存空间 10。
内筒 2在旋转时， 颗粒 8会在离心力的作用下， 沿刮板 6斜向上或斜向下运动， 此 时， 内筒 2的旋转速度不需要很高， 只需要洗涤速度即可实现， 一般可选择以 50-150 转 /min的转速运转。
当内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相反时， 并且以该方向连续运 转， 颗粒 8会在刮板 6的带动下斜向上向内筒 2方向运动， 穿过通道 12， 进入内筒 2内， 完成颗粒 8向内筒 2内的投放。
当内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相同时， 并且以该方向连续运 转， 颗粒 8会在刮板 6的带动下斜向下向储存空间 10方向运动， 穿过通道 12， 离开内 筒 2， 进入储存空间 10内， 完成颗粒 8向储存空间 10内的回收。
在该回收过程中， 绝大部分颗粒 8会回收至储存空间 10内， 此时， 高速旋转内筒 2和延伸部， 一般以 100-1000转 /min的转速运转， 内筒 2和延伸部的旋转方向与刮板 6 的倾斜方向相同， 对内筒 2内的衣物 5和储存空间 10内的颗粒 8同时进行脱水， 实现颗 粒 8的再生利用， 在该脱水的过程中， 剩余的颗粒 8可以继续被分离和回收， 从而实 现颗粒 8的 100%的回收。
如果储存空间 10位于内筒 2的顶部一侧， 则在颗粒 8投放和回收时， 内筒 2的转动 方向与上述相反。
在洗涤过程中， 内筒 2是正反转交替运转的， 颗粒 8在刮板 6的带动下在内筒 2内 不断的进行前进和后退， 颗粒 8顺着刮板 6斜向上或斜向下交替运动， 当运动到一定 高度时， 颗粒 8会从刮板 6上掉落至内筒 2内实现翻转。
下面结合图 1至图 4对使用上述滚筒洗衣机的洗涤方法进行详细说明。
该洗涤方法包括如下步骤：
步骤一：将待洗衣物 5加入至洗衣机的隔离筒 9内，同时打开外筒 1上方的进水口， 向外筒 1内注水， 洗涤用水和洗涤剂混合后进入外筒 1内， 水穿过内筒 2上的开孔 3及 隔离筒 9， 进入隔离筒 9内与待洗衣物 5充分混合， 此过程， 只需要加入适量的水和洗 涤剂， 保证水能浸泡过衣物 5。
在注入洗涤水浸泡待洗衣物 5时， 使待洗衣物 5静置， 浸泡一定时间， 使水与衣 物 5充分浸润， 以进一步提高洗净的效果。
步骤二： 如图 3所示， 驱动内筒 2转动， 内筒 2和延伸部的旋转方向与刮板 6的倾 斜方向相反， 并且以该方向连续运转， 颗粒 8在离心力的作用下贴近内筒 2的筒壁， 同时会在刮板 6的带动下斜向上向内筒 2方向运动，穿过通道 12，不断地进入内筒 2内， 完成颗粒 8向内筒 2内的投放。
在颗粒 8投放的过程中， 已进入内筒 2内的颗粒 8会在刮板 6的带动下不断掉落翻 转， 与衣物 5充分混合。
在此步骤中， 内筒 2的转速在 100- 150转 /mi n之间效果最佳。
步骤三： 如图 1所示， 当颗粒 8全部投放至内筒 2内后， 此过程可以通过限定投放 时间来控制， 通过驱动装置 4驱动内筒 2正转一定时间， 停止， 再反转一定时间， 刮 板 6也交替地正向旋转和反向旋转， 进而颗粒 8在内筒 2内会不断的进行前进或后退， 颗粒 8顺着刮板 6斜向上运动， 到一定高度时， 颗粒 8向下翻转掉落至内筒 2内， 实现 前后方向上的翻转。 在洗涤过程中， 衣物 5在提升块 13的作用下进行上下方向上的翻 转。
在洗涤过程中， 颗粒 8、 衣物 5和洗涤水充分混合， 并不断地在提升块 13的作用 下进行提升和下降， 完成衣物 5的洗涤。
在此步骤中， 内筒 2的转速在 100-200转 /min之间效果最佳。
步骤四： 如图 4所示， 洗涤结束后， 驱动内筒 2转动， 在转动过程中， 颗粒 8会与 衣物 5进行分离， 此时， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相同， 并且以 该方向连续运转， 颗粒 8在离心力的作用下贴近内筒 2的筒壁， 同时颗粒 8会在刮板 6 的带动下斜向下向储存空间 10方向运动， 穿过通道 12， 颗粒 8不断地被分离， 也不断 地离开内筒 2而进入储存空间 10内， 完成颗粒 8向储存空间 10内的回收。
在此步骤中， 内筒 2的转速在 100- 150转 /mi n之间效果最佳。
步骤五： 当颗粒 8与衣物 5分离并回收后， 高速旋转内筒 2， 对内筒 2内的衣物 5和 储存空间 10内的颗粒 8同时进行脱水， 实现颗粒 8的再生利用， 水集存在外筒 1内并从 外筒 1下方的排水口排出。 此过程中， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向 相同， 可以使剩余的颗粒 8继续被分离和回收， 从而实现颗粒 6的 100%的回收。
在此步骤中， 内筒 2的转速以 100-1000转 /min的转速运转， 通常要高于洗涤时的 转速。
步骤六： 漂洗步骤， 重新向外筒 1内加入适量的干净水， 依上述过程对衣物 5进 行漂洗， 此时， 干净水同样会进入储存空间 10内， 在衣物 5漂洗的同时， 也对颗粒 8 进行漂洗， 漂洗后再次进行上述的脱水过程， 使进入内筒 2内的少量颗粒 8被分离和 回收， 最终完成衣物 5的全部洗涤过程。
实施例二：
与实施例一的区别之处在于， 先执行实施例一中所述的步骤五， 驱动内筒 2和延 伸部高速旋转， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相同， 对衣物 5及颗粒 8进行脱水， 在脱水的同时， 也实现了衣物 5与颗粒 8的分离， 同时， 部分颗粒 8在刮 板 6的带动下斜向下向储存空间 10方向运动， 回收至储存空间 10内。
然后再执行实施例一中的步骤四， 驱动内筒 2和延伸部以洗涤转速旋转， 内筒 2 和延伸部的旋转方向与刮板 6的倾斜方向相同， 并且以该方向连续运转， 可以使剩余 的颗粒 8继续被分离和回收， 从而实现颗粒 8的 100%的回收。
实施例三：
与实施例一的区别之处在于， 删除实施例一中所述的步骤四， 直接执行实施例 一中所述的步骤五， 驱动内筒 2和延伸部高速旋转， 内筒 2和延伸部的旋转方向与刮 板 6的倾斜方向相同， 对衣物 5及颗粒 8进行脱水， 在脱水的同时， 也实现了衣物 5与 颗粒 8的分离， 同时， 颗粒 8在刮板 6的带动下斜向下向储存空间 10方向运动， 回收至 储存空间 10内。 此过程， 需要内筒 2高速旋转的时间加长， 以保证颗粒 8全部回收至 储存空间 10内。
实施例四：
与实施例一的区别之处在于， 储存空间 10可以是储存盒的结构， 设置在外筒 1的 外壁上， 储存空间 10穿过外筒 1的筒壁直接与内筒 2连通， 储存空间 10与内筒 2之间的 连通孔设置于内筒 2的端部位置。
洗涤结束后， 驱动内筒 2转动， 在转动过程中， 颗粒 8会与衣物 5进行分离， 此时， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相同， 并且以该方向连续运转， 颗粒 8 在刮板 6的带动下斜向下向储存空间 10方向运动， 通过连通孔进入储存空间 10内， 颗 粒 8不断地被分离， 也不断地离开内筒 2而进入储存空间 10内， 完成颗粒 6向储存空间 10内的回收。
实施例五：
与上述四个实施例不同之处在于， 刮板 6的倾斜方向正好相反， 刮板 6两端点之 间的连线相对于内筒 2轴心线之间的夹角 7为钝角。 此结构情况下， 内筒 2在颗粒 8投 放过程和回收过程中的旋转方向刚好与上述实施例中的方向相反。
在颗粒 8的投放过程中， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相同， 并 且以该方向连续运转， 颗粒 8会在刮板 6的带动下斜向下向内筒 2方向运动， 穿过通道 12， 不断地进入内筒 2内， 完成颗粒 8向内筒 2内的投放。
在颗粒 8的回收过程中， 内筒 2和延伸部的旋转方向与刮板 6的倾斜方向相反， 并 且以该方向连续运转， 颗粒 8会在刮板 6的带动下斜向上向储存空间 10方向运动， 穿 过通道 12， 颗粒 8不断地被分离， 也不断地离开内筒 2而进入储存空间 10内， 完成颗 粒 8向储存空间 10内的回收。
实施例六：
与上述实施例一至五不同之处在于， 刮板 6由内筒 2的底部向顶部螺旋盘绕设置， 图中未示出， 这样内筒 2在旋转时， 颗粒 8会在离心力的作用下， 沿螺旋盘绕的刮板 6 斜向上或斜向下螺旋运动，此时，内筒 2的旋转速度与前述相同，一般可选择以 50-150 转 /min的转速运转。
当内筒 2和延伸部的旋转方向与刮板 6的螺旋方向相同时， 并且以该方向连续运 转， 颗粒 8会在刮板 6的带动下斜向上向内筒 2方向运动， 穿过通道 12， 进入内筒 2内， 完成颗粒 8向内筒 2内的投放。
当内筒 2和延伸部的旋转方向与刮板 6的螺旋方向相反时， 并且以该方向连续运 转， 颗粒 8会在刮板 6的带动下斜向下向储存空间 10方向运动， 穿过通道 12， 离开内 筒 2， 进入储存空间 10内， 完成颗粒 8向储存空间 10内的回收。 在该回收过程中， 绝大部分颗粒 8会回收至储存空间 10内， 此时， 高速旋转内筒 2和延伸部， 一般以 100-1000转 /min的转速运转， 内筒 2和延伸部的旋转方向与刮板 6 的螺旋方向相反， 对内筒 2内的衣物 5和储存空间 10内的颗粒 8同时进行脱水， 实现颗 粒 8的再生利用， 在该脱水的过程中， 剩余的颗粒 8可以继续被分离和回收， 从而实 现颗粒 8的 100%的回收。
在洗涤过程中， 内筒 2是正反转交替运转的， 颗粒 8在刮板 6的带动下在内筒 2内 不断的进行前进和后退， 颗粒 8顺着刮板 6斜向上或斜向下交替螺旋运动， 当运动到 一定高度时， 颗粒 8会从刮板 6上掉落至内筒 2内实现翻转。
如上所述， 结合附图所给出的方案内容， 可以衍生出类似的技术方案。 但凡是 未脱离本发明技术方案的内容， 依据本发明的技术实质对以上实施例所作的任何简 单修改、 等同变化与修饰， 均仍属于本发明技术方案的范围内。
