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：
如图1所示，本发明提供的一种干衣机，包括水槽1和储水盒2，水槽1安装在干衣机的底部，储水盒2安装于干衣机的顶部，储水盒2可以单独取出，清理后可再安装回干衣机内。水槽1和储水盒2之间连接有排水管3和回水管4，排水管3和回水管4可以采用塑料管或金属管，在排水管3上接有排水泵5，排水管3的出水口位于储水盒2的上方，回水管4顶部的进水口8与储水盒2连接，位于储水盒2水满溢水的位置，回水管4底部的出水口与水槽1的入水口6连接，在水槽1内设置有浮子开关7，用于检测水槽1内的水位。
冷凝水先被收集在底部的水槽1里，当浮子开关7检测到水槽1内的水位达到设定值时，向干衣机的控制器(图中未示出)发出信号，控制器接收到信号后，启动排水泵5，将水槽1里的冷凝水排到顶部的储水盒2里进行储存。当储水盒2内的冷凝水达到满位状态时，冷凝水就会从回水管4顶部与储水盒2连通的进水口8处溢出，顺着回水管4流回底部的水槽1。
如图1所示，在回水管4上安装有一水流检测装置9，水流检测装置9与干衣机的控制器连接，在干衣机上还设置有报警提醒装置(图中未示出)。报警提醒装置可以为蜂鸣器、报警灯、语音提示装置、控制面板显示单元中的任一种，也可以采用多种组合的形式。
本发明提供的干衣机提醒清理储水盒的方法是，当储水盒2内的冷凝水达到满位状态溢出进入回水管4后，水流检测装置9就会检测到在回水管4内的水流，并向控制器发生信号，控制器接收到信号后，控制报警提醒装置报警，提醒用户储水盒2已满，需要清理储水盒2了。
实施例一：
如图2所示，本实施例中，水流检测装置9包括杠杆10和开关11，开关11与控制器连接，杠杆10穿过回水管4的管壁，一部分在回水管4的内部，一部分在回水管4的 外部，杠杆10以与管壁的接触点为支点12，开关11对应杠杆10的端部设置。为了保证即使有少量水流流出也可以精确检测，优选杠杆10伸入至回水管4内部的长度大于回水管4的半径，更优选在回水管4的2/3的位置，且将杠杆10的安装位置设置在回水管4的底部位置，保证有较小的水流时也会对杠杆10产生较大的冲击力，杠杆10采用金属片或塑料片，以增加杠杆10与水流的可接触面积。
在杠杆10与回水管4管壁接触的支点12位置设置有用于密封的密封垫或密封圈(图中未示出)，既不影响杠杆10的运动，又可保证支点12处不会漏水。
在储水盒2未到满水状态，无水流溢出时，杠杆10处于平衡状态，杠杆10的端部与开关11的触点相分开。
当有水从储水盒2内溢出进入回水管4内时，水流沿回水管4向下流动的过程中，会对伸入至回水管4内的杠杆10产生向下的冲击力，此时，杠杆10失去平衡，杠杆10位于回水管4外部的端部向下翘起，与开关11的触点碰触，继而触发开关11，开关11向干衣机的控制器发出信号，控制器接收到信号后，向报警提醒装置发出报警指令，进而控制报警提醒装置报警，提醒用户储水盒2已满，需要清理储水盒2了。
实施例二：
如图3所示，本实施例中，水流检测装置9包括两个平行设置的金属极板13，两个金属极板13固定在回水管4的管壁上，两个金属极板13分别连接一根电线14。本实施例中，优选将两个金属极板13穿过回水管4的管壁安装，电线14与金属极板13连接的位置处于回水管4的外部，可以方便安装且可保证安全，在金属极板13穿过回水管4管壁的位置设置有用于密封的密封垫或密封圈(图中未示出)，保证穿过的位置不会漏水。两条电线14的另一端与电导率探测器15连接，电导率探测器15与控制器连接。
在储水盒2未到满水状态，无水流溢出时，电导率探测器15检测两个金属极板13之间的电导率，此时电导率为一固定值。
当有水从储水盒2内溢出进入回水管4内时，水流沿回水管4向下流动经过两个金属极板13时，两个金属极板13之间的电导率就会急剧下降，电导率探测器15将检测到的电导率传输至控制器，控制器内预先存储有某一设定值，或预设两个金属极板13间在无水状态时电导率的变化范围，当电导率达到预先存储的设定值或超出预设的变化范围时，控制器即向报警提醒装置发出报警指令，进而控制报警提醒装置报 警，提醒用户储水盒2已满，需要清理储水盒2了。
实施例三：
如图3所示，本实施例中，水流检测装置9包括气室16及压力传感器17，气室16设置在回水管4的外侧，气室16的壁与回水管4一体成型或焊接在回水管4的管壁上，在回水管4的管壁上开有一将回水管4的内腔与气室16连通的气孔18，气孔18优选开在回水管4的底部位置，气孔18同样位于气室16的底部，在气室16的顶部设置有排气口19，排气口19连接一导压管20，导压管20的顶部设置压力传感器17，压力传感器17用于检测气室16的气压，压力传感器17与控制器连接。
在储水盒2未到满水状态，无水流溢出时，气室16内的气压与回水管4内的气压相同，压力传感器17检测气室16内的气压，此时气室16内的气压为一固定值，将该固定值预存至控制器内。
当有水从储水盒2内溢出进入回水管4内时，水流沿回水管4向下流动经过气孔18，此时，气室16内的压力就会出现变化，气室16内的压力升高，压力传感器17随时检测气室16内的气压，并将检测的结果传输至控制器，在控制器内预先存储有某一设定值，或预设气室16在无水状态时气压的变化范围，当气室16内的压力达到预先存储的设定值或超出预设的变化范围时，控制器即向报警提醒装置发出报警指令，进而控制报警提醒装置报警，提醒用户储水盒2已满，需要清理储水盒2了。
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。
