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 6， 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。
内筒 2的侧壁呈螺旋状， 为保证颗粒 6在内筒 2内与衣物 5充分混合， 同时保证颗 粒 6全部回收， 内筒 2的侧壁由其底部至顶部布满螺纹。 为了不伤及颗粒， 同时为了 增大螺纹内储存颗粒 6的容量， 本实施例， 螺纹的横断面优选采用流线形， 大致呈圆 弧状。 颗粒 6的直径大约在 2_3mm的范围内， 所以螺纹的螺距选取大于或等于 5mm， 优 选为 8- 15mm， 更优选采用 10mm， 螺纹的横断面高度选取大于或等于 5mm， 优选为 8-15mm, 更优选采用 10mm。 螺纹的螺距越大， 横断面的高度越大， 螺纹的圆弧内所 能储存的颗粒 6数量就越多， 螺纹带动颗粒 6的推进速度也就越快， 则更有利于颗粒 6 的投放和回收， 同时也有利于颗粒 6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， 在内筒 2的内壁上设置有至少一个向内突出的提升块 (图中未示出）， 在洗涤过程中， 衣服 5在提升块的作用下， 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， 提升块的数量可选择 1-3个， 本实施例中， 优选采用 3个提升块， 沿内筒 2的周向均匀分布。 同时， 内筒 2是交替正 反旋转的， 在内筒 2筒壁的螺纹交替的正反旋转带动下， 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。
为了方便衣物 5与颗粒 6的分离， 沿内筒 2的内侧设置一圈隔离筒 8， 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， 隔离筒 8与内筒 2同步旋转。 隔离筒 8呈网状结构， 以便颗粒 6和洗涤水更容易流进或 流出， 衣物 5被隔离在隔离筒 8内， 颗粒 6则被隔离在隔离筒 8和内筒 2之间， 上述的提 升块穿过隔离筒 8伸入至隔离筒 8的内部， 提升块也可以直接设置在隔离筒 8的内侧。 在洗涤时， 颗粒 6穿过隔离筒 8与衣物 5充分混合， 颗粒 6优选采用高分子表面多孔的 材料， 利用颗粒 6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。
在洗衣机内设置有用于储存固体颗粒 6的储存空间 9， 储存空间 9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。 本实施例中， 如图 1所示， 内筒 2向底部方向延伸， 延伸部的侧壁与内筒 2的侧壁相一致呈螺旋状， 并与内筒 2的侧壁形成连续的螺旋， 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 9， 为了方便投取衣物 5， 储存空间 9可以采用圆环状。
储存空间 9与内筒 2连通， 储存空间 9与内筒 2之间设置一用地阻挡衣物 5的挡板 10， 挡板 10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 10周圈与内筒 2的内壁之间具有用于将储存空间 9与内筒 2相 互连通的通道 7， 挡板 10阻挡衣物 5不能进入储存空间 9， 颗粒 6则通过该通道 7进出储 存空间 9。
内筒 2在旋转时， 颗粒 6会在离心力的作用下， 置于螺纹形成的圆弧槽内， 螺纹 的旋转就会带动颗粒 6前进或后退， 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 50-200转 /min的转速运转。
如图 2所示， 由于本实施例中， 储存空间 9位于内筒 2的底部一侧， 当内筒 2和延 伸部的旋转方向与螺纹方向相同时， 并且以该方向连续运转， 颗粒 6会在螺纹的推动 下向内筒 2方向运动， 穿过通道 7， 进入内筒 2内， 完成颗粒 6向内筒 2内的投放。
当内筒 2和延伸部的旋转方向与螺纹方向相反时， 并且以该方向连续运转， 颗粒 6会在螺纹的推动下向储存空间 9的方向运动， 穿过通道 7， 离开内筒 2， 进入储存空 间 9内， 完成颗粒 6向储存空间 9内的回收。
在该回收过程中， 绝大部分颗粒 6会回收至储存空间 9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螺纹方 向相反， 对内筒 2内的衣物 5和储存空间 9内的颗粒 6同时进行脱水， 实现颗粒 6的再生 利用， 在该脱水的过程中， 剩余的颗粒 6可以继续被分离和回收， 从而实现颗粒 6的 100%的回收。
如果储存空间 9位于内筒 2的顶部一侧， 则在颗粒 6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， 在内筒 2筒壁螺纹的交替的正反旋 转的带动下， 颗粒 6的在内筒 2内会不断的进行前进和后退， 颗粒 6顺着螺纹向上呈螺 旋运动， 到一定高度时， 由于自身的重力作用， 颗粒 6在向下翻转掉落至内筒 2内， 实现前后方向上的翻转。
下面结合图 1至图 3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 8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 8， 进入隔离筒 8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 2所示， 驱动内筒 2转动， 内筒 2和延伸部的旋转方向与螺纹方向相 同， 并且以该方向连续运转，颗粒 6会在螺纹的带动下向内筒 2方向运动， 穿过通道 7， 不断地进入内筒 2内， 完成颗粒 6向内筒 2内的投放。
在颗粒 6投放的过程中， 已进入内筒 2内的颗粒 6会在旋转的螺纹的带动下不断翻 转， 与衣物 5充分混合。
在此步骤中， 内筒 2的转速在 100-200转 /min之间效果最佳。
步骤三： 如图 1所示， 当颗粒 6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， 螺 纹交替地正向旋转和反向旋转， 进而颗粒 6在内筒 2内会不断的进行前进和后退， 颗 粒 6顺着螺纹向上运动， 到一定高度时， 由于自身的重力作用， 颗粒 6在向下翻转掉 落至内筒 2内， 实现前后方向上的翻转。
在洗涤过程中， 颗粒 6、 衣物 5和洗涤水充分混合， 并不断地在提升块的作用下 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 3所示， 洗涤结束后， 驱动内筒 2转动， 在转动过程中， 颗粒 6会与 衣物 5进行分离， 颗粒 6会积存在螺纹的圆弧槽内， 此时， 内筒 2和延伸部的旋转方向 与螺纹方向相反， 并且以该方向连续运转， 颗粒 6会在螺纹的带动下向储存空间 9方 向运动， 穿过通道 7， 颗粒 6不断地被分离， 也不断地离开内筒 2而进入储存空间 9内， 完成颗粒 6向储存空间 9内的回收。
在此步骤中， 内筒 2的转速在 100-200转 /min之间效果最佳。
步骤五： 当颗粒 6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 9内的颗粒 6同时进行脱水， 实现颗粒 6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螺纹方向相反， 可以使剩余的颗粒 6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 9内， 在衣物 5漂洗的同时， 也对颗粒 6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 6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螺纹方向相反， 对衣物 5及颗粒 6进行脱 水， 在脱水的同时， 也实现了衣物 5与颗粒 6的分离， 同时， 部分颗粒 6在螺纹的带动 下向储存空间 9方向运动， 回收至储存空间 9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螺纹方向相反， 并且以该方向连续运转， 可以使剩余的颗粒 6 继续被分离和回收， 从而实现颗粒 6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螺 纹方向相反， 对衣物 5及颗粒 6进行脱水， 在脱水的同时， 也实现了衣物 5与颗粒 6的 分离， 同时， 颗粒 6在螺纹的带动下向储存空间 9方向运动， 回收至储存空间 9内。 此 过程， 需要内筒 2高速旋转的时间加长， 以保证颗粒 6全部回收至储存空间 9内。
实施例四：
与实施例一的区别之处在于， 储存空间 9可以是储存盒的结构， 设置在外筒 1的 外壁上， 储存空间 9穿过外筒 1的筒壁直接与内筒 2连通， 储存空间 9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 6会与衣物 5进行分离， 颗粒 6会积存在螺纹的圆弧槽内， 此时， 内筒 2和延伸部的旋转方向与螺纹方向相反， 并 且以该方向连续运转， 颗粒 6会在螺纹的带动下向储存空间 9方向运动， 通过连通孔 进入储存空间 9内， 颗粒 6不断地被分离， 也不断地离开内筒 2而进入储存空间 9内， 完成颗粒 6向储存空间 9内的回收。
实施例五：
对于波轮洗衣机， 与实施例一中所述的滚筒洗衣机相同， 内筒的侧壁呈螺旋状， 在洗涤过程中， 内筒交替正反旋转， 在内筒筒壁的螺纹交替的正反旋转带动下， 颗 粒在内筒内还会不断的进行沿内筒的轴线上下方向上的运动及翻转， 使衣物与颗粒 混合更加充分， 提高了洗净率。
与实施例一所述相同， 为了方便衣物与颗粒的分离， 沿内筒的内侧设置一圈隔 离筒， 隔离筒与内筒之间可通过紧固件固定连接， 与内筒同步旋转。 隔离筒呈网状 结构， 以便颗粒和洗涤水更容易流进或流出， 衣物被隔离在隔离筒内， 颗粒则被隔 离在隔离筒和内筒之间。
与实施例一所述相同， 颗粒的储存空间为内筒向下延伸的延伸部， 延伸部的侧 壁为与内筒的侧壁相一致的螺旋状， 并与内筒的侧壁形成连续的螺旋。 储存空间与 内筒连通， 储存空间与内筒之间设置一挡板， 挡板周圈与内筒 2的内壁之间具有用于 将储存空间与内筒相互连通的通道， 挡板阻挡衣物不能进入储存空间， 颗粒通过该 开口进出储存空间。
本实施例中所述的波轮洗衣机的洗涤过程与实施例一、 实施例二和实施例三所 述相同， 这里不再另做详细描述。
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。
