本发明的最佳实施方式
[0023] 实施例一
[0024] 参见图 1到图 3， 对本发明最佳实施例的技术方案进行详细描述。
[0025] 本发明所述的带自清理功能的线屑过滤系统， 包括带有进风口 12和出风口 13的 壳体 5、 壳体 5的左侧壁幵有小孔 I 14， 外壁安装有驱动电机 1， 驱动电机 1的动力 输出轴穿过小孔 I伸入到壳体 5的内部。 壳体 5的右侧壁与小孔 I相对应的位置设有 小孔 II 15， 螺杆 2的一端与驱动电机 1的输出轴配合， 螺杆 2的另一端安装在与电 机输出轴相对壳体壁面的小孔 II中， 为了减小摩擦螺杆 2与小孔 II的磨擦， 小孔 II 中装有轴承， 螺杆 2的右端插装在轴承中。

[0027] 清理单元 3的下部与过滤网 7接触的部位采用毛刷或者硅胶或者橡胶刷， 能够有 效地清理线屑， 但不会损伤过滤网。
[0028] 如图 2中所示， 为本发明所述过滤系统的工作状态示意图。 干衣机滚筒中带有 线屑的风从壳体 5的进风口 12进入过滤系统， 经过滤网 7过滤后从出风口 13中排 出。 线屑留在过滤网 7上方， 驱动电机 1的输出轴正反转运动， 带动与其螺纹连 接的螺杆 2作直线往复运动。 螺杆 2带动清理单元 3作直线往复运动， 清理单元 3 下部的毛刷清理过滤网 7上的线屑。 线屑堆积在线屑堆积板 9处， 如图 3所示， 当 步进电机 6控制线屑堆积板 9的幵启和关闭， 线屑堆积板 9打幵将线屑倒入到线屑 收集抽屉 8中。 壳体 5右侧壁设有过滤网取放口 10和线屑收集抽屉取放口 11。 通 常地， 带自清理功能的过滤系统是干衣机烘干衣服完毕清理单元启动工作。 当 然， 对于大型烘干机或者用于烘干能产生较多毛屑衣物的烘干机， 可以设置在 烘干过程中间进行一次线屑清理， 因为适当清理是会减小风阻， 有利于烘干。
[0029] 在本最佳实施例中， 线屑收集抽屉中安装有光电传感器， 光电传感器设置在线 屑收集抽屉中远离线屑堆积板的一端。 光电传感器的发射端和接收端分别安装 在抽屉的相对两侧的左壁、 右壁， 当光电传感器接收端无信号接收吋， 说明线 屑已经堆积满线屑， 此吋干衣机控制面板显示线屑已满的闪烁信号， 或者采用 语音形式提醒用户， 将线屑收集抽屉 8从线屑收集抽屉取放口 11中取出， 将线屑 倒掉。
[0030] 实施例二
[0031] 带自清理功能过滤系统的驱动装置的另一种方式， 驱动电机 1、 螺杆 2置于壳体 的中间部位， 清理单元 3的上部的中间部位与螺杆 2通过螺纹方式配合， 壳体的 前后侧壁上均设有滑轨， 清理单元上部的前端、 后端装有轴承并装在前、 后滑 轨中。
[0032] 实施例三
[0033] 带自清理功能过滤系统的线屑收集的另一种方式， 线屑收集抽屉的上方设有线 屑堆积板， 线屑堆积板装有复位弹簧， 线屑堆积板在线屑的重力作用下幵启， 在复位弹簧作用下关闭。
[0034] 本发明还涉及使用上述带自清理功能过滤系统的干衣机， 通过改进过滤系统的 结构， 结构紧凑， 可靠性强， 提高干衣机线屑收集效率， 从而也提高烘干效率
[0035] 当然， 本发明并不限于上述举例， 所应用的产品包括但不限于干衣机、 ， 还包括带干衣功能的滚筒洗衣机、 带干衣功能的波轮洗衣机， 对于本领域技术 人员来说显而易见的技术方案， 在不脱离本发明的精神或范围的情况下， 对本 发明做各种修改和改变在本发明权利要求及其等同替换的范围内， 本发明涵盖 这样的修改和改变。
