本专利申请要求2014年8月7日申请的，申请号为201410384585.1，名称为“一种排水装置、方法及除湿机”的中国专利申请的优先权，在此将其全文引入作为参考。
本发明涉及空调技术领域，尤其涉及一种排水装置、方法及除湿机。
空气调节设备在运行过程中会产生冷凝水，需要将冷凝水排到设备外。例如，除湿机又称为抽湿机、干燥机、除湿器，一般可分为家用除湿机和工业除湿机两大类。通常，除湿机由压缩机、热交换器、风扇、盛水器、机壳及控制器组成。由风扇将潮湿空气抽入机内，通过热交换器，此时空气中的水分子冷凝成水珠，处理过后的干燥空气排出机外，如此循环使室内湿度保持在适宜的相对湿度。除湿机常用的排水方式是通过水箱或连续排水接口进行排水，这两种方式在日常使用中不会对用户产生太大影响，但当除湿机位于较低地势，水需往高处排出时这两种方式就不可行。借助水泵产生的动力使水从低处往高处排出是常见的处理方式。除湿机内置水泵的工作原理就是除湿所得到的水通过接水盘流向水箱，当水箱水位达到某一高度时，水泵启动，水通过水泵排出流向高处；当水位下降到某一高度时，水泵停止工作。目前，内置水泵水位检测的主要是通过浮子检测，该检测方法利用浮子在水中的浮力判断水箱中水位，从而控制水泵开停。该方式存在可靠性不高，对水位检测不够灵敏等缺陷，容易导致误判从而影响水泵工作。

时，即水流检测装置检测到冷凝水的流量大于预设值时，水泵会持续运行。
水流量传感器一般为霍尔型水流量传感器，由铜阀体、水流转子组件、稳流组件和霍尔元件组成，当水管中的水流过转子组件时，磁性转子转动，并且转速随着流量成线性变化，霍尔元件输出相应的脉冲信号反馈给控制装置。控制装置根据脉冲信号即能判断出水管中的流量。
如图3所示，提供一种根据本发明实施例的除湿机，该除湿机包括排水装置。接水盘21用于收集冷凝水，冷凝水汇集在冷凝水收集装置中，即二级水箱25中。水泵22通过水管26与二级水箱25和出水口23连接。在水管连接处安装水流检测装置24，通过水流检测装置24检测水管中26的水流状态，反馈信号给除湿机控制器，用于控制水泵22的开停。除湿机通电启动情况下，在压缩机启动后水泵22会同时启动，水流检测装置24开始检测水管26中水流状态，判断冷凝水收集装置是否存在冷凝水。
图4为根据本发明的排水方法的一个实施例的流程图。如图所示：
步骤401，获取水泵的水管中的水流量信息。水泵通过水管与冷凝水收集装置和空气调节装置的出水口连接，水流检测装置检测水管中的水流量并将检测的流量信息发送给控制装置。
步骤402，根据水流量信息控制水泵运行。控制装置根据流量信息控制水泵启动、停止。
上述实施例中的排水方法，根据水流检测装置检测水管流量控制水泵的开停，能够更准确判断冷凝水的状态，使水泵运行更有效率。
图5为根据本发明的排水方法的另一个实施例的流程图，如图5所示：
步骤501，空气调节装置的压缩机运行。
步骤502，水泵运行排除冷凝水。
步骤503，水流检测装置检测水管中的水流量，当判断水管中的流量大于预设的流量阈值时，控制水泵运行。当判断水管中的流量小于预设的流量阈值时，控制水泵停止，进入步骤505。
步骤504，当水泵运行时，第一计时器单元计算水泵运行的时间并存储，并在水泵停止时停止计时。
步骤506，第二计时器单元在水泵停止时开始计算水泵停止时间。
步骤507，当水泵的停止运行时间超过预设的停止时长阈值时，向运行控制单元发送运行信号，根据运行信号控制水泵启动。
根据本发明的一个实施例，当水泵运行时，控制装置的第一计时器单元开始计算水泵运行时间t，直到检测到冷凝水的流量小于预设值时，水流检测装置反馈信号给控制装置，
控制水泵停止运行，第一计时器单元停止计时，控制装置的第二计时器单元开始计算水泵停止时间T，当T达到设定的停止时长阈值后，水泵再次启动，如此循环。
上述实施例中的排水方法，保证冷凝水收集装置中的冷凝水能够及时有效的排出，同时能够避免水泵空转而引起故障。
根据本发明的一个实施例，第一计时器单元可以协助修订第二计时器单元中预设的停止时长阈值。第一计时器单元获取最后2次时间数值，分别标示为t1、t2，同时计算记录△t＝t2-t1。第一计时器单元计算所存储的最后一个水泵运行时长t1与倒数第二个水泵运行时长t2的差值△t。
当第二计时器单元判断差值的绝对值大于预设的时间差阈值并且差值为正时，将停止时长阈值增加预设的时长。当第二计时器单元判断差值的绝对值大于预设的时间差阈值并且差值为负时，将停止时长阈值减去预设的时长。
例如：预设的停止时长阈值的初始值为3min，当-5S≤△t≤5S时，预设的停止时长阈值维持不变；当△t＜-5S时，水泵停止时间T增加1min；当△t＞5S时，预设的停止时长阈值减少1min。
通过本发明提供的排水装置、方法及除湿机，根据水流检测装置检测水管流量控制水泵的开停，能够更准确判断冷凝水的状态，提高设备的可靠性，使水泵运行更有效率，能够节约能源、节约运行成本。
可能以许多方式来实现本发明的方法和系统。例如，可通过软件、硬件、固件或者软件、硬件、固件的任何组合来实现本发明的方法和系统。用于方法的步骤的上述顺序仅是为了进行说明，本发明的方法的步骤不限于以上具体描述的顺序，除非以其它方式特别说明。此外，在一些实施例中，还可将本发明实施为记录在记录介质中的程序，这些程序包括用于实现根据本发明的方法的机器可读指令。因而，本发明还覆盖存储用于执行根据本发明的方法的程序的记录介质。
本发明的描述是为了示例和描述起见而给出的，而并不是无遗漏的或者将本发明限于所公开的形式。很多修改和变化对于本领域的普通技术人员而言是显然的。选择和描述实施例是为了更好说明本发明的原理和实际应用，并且使本领域的普通技术人员能够理解本发明从而设计适于特定用途的带有各种修改的各种实施例。
