Description
本发明涉及一种无水检测方法及装置，具体地涉及一种泵浦式锅炉熨斗的无水检测方法、装置。
传统的泵浦式电熨斗，都具有一个带握把的壳体，壳体内设有水箱和泵浦，锅炉的底部设置用于加热水以产生蒸汽的电热盘，壳体上设有电源开关。泵浦负责控制水箱中的水进入锅炉，以产生蒸汽。现有电熨斗产生蒸汽的方式大部分为喷蒸汽式，即水箱中的水通过泵浦连续滴进锅炉的电热盘，连续产生少量蒸汽并且该蒸汽从电热盘锅炉上的出汽孔连续地向外喷出。为避免干烧，使用时水箱中需保持有水，因而需要设有对水箱有无水状态的检测装置。
以前针对水箱无水侦测使用的方法有：（1）使用磁簧开关配合磁铁。将含有磁铁的浮子放在水箱里，有水浮子就会浮起磁簧开关就会侦测到磁浮位置的变化，感应到无水。（2）将金属探针放入水管中，有水或没有水探针之间就会有阻值变化，以此作为无水侦测的依据。
但是以上的方案都需要至少一组硬件来侦测无水功能，成本会有所增加。
本发明的目的在于提供一种锅炉熨斗的无水检测方法及其装置，以解决现有技术中存在的上述问题。本发明根据锅炉在有水和无水情况下，显示出不同的温度特性来检查判定水箱里是否还有水。
本发明提供的技术方案如下：
技术方案一：

步骤二、控制基板接受恒温器信号，判断恒温器是否跳开过一次；如果判断结果为否，执行步骤一，如果判断结果为是，则执行步骤三；
步骤三、电热盘为已加热至随时可出蒸汽状态，之后执行步骤四；
步骤四、判断是否需要出蒸汽，如果判断结果为否，执行步骤三，如果判断结果为是，则执行步骤五；
步骤五、判断恒温器跳开时间是否超过预先设定的判断值，如果判断结果为否，执行步骤四，如果判断结果为是，则判断为无水。

以及控制基板，在锅炉恒温器与控制基板之间连接有一根信号线，该装置至少包括判断单元和检测单元，

该检测单元用于检测恒温器断开时间是否超过预定值，如果是，则判断水箱无水。
技术方案三：
一种具有无水检测装置的熨斗，其特征在于，该熨斗具有无水检测装置，该装置使用了恒温锅炉的常闭的恒温器以及控制基板，在锅炉恒温器与控制基板之间连接有一根信号线，该控制基板至少包括判断单元和检测单元，该判断单元用于判断恒温器是否断开过一次，如果否，判断为电熨斗通电等待状态，如果是，调用检测单元；该检测单元用于检测恒温器断开时间是否超过预定值，如果是，则判断水箱无水。
由上述描述可知，本发明只在传统锅炉熨斗的恒温器与控制基板之间加了一根信号线，通过该信号线将恒温器闭合、跳开判断的情况提供给控制基板，控制基板就可根据实际电加热系统的经验值判断出水箱是否有水，以控制泵浦不会因空抽而损坏，和传统使用其它硬件侦测的成本相比，本发明成本及其低廉，且工艺简单，并为熨斗其它部件的设计节省了更多的空间。
图1为本发明实施例的控制电路图；
图2为本发明实施例的逻辑判断示意图。
参照图1和图2，锅炉熨斗的无水检测方法，该方法使用了恒温锅炉的常闭的恒温器2以及控制基板1，在锅炉恒温器2与控制基板1之间连接有一根信号线3，该控制基板1包括一检测单元以及一判断单元，该检测单元接受恒温器的断开和闭合状态信息，该判断单元通过恒温器断开和闭合信息来判断水箱是否无水。
该方法具体包括以下步骤：
步骤零，电熨斗上电，开始进入工作状态；
步骤一、锅炉处于等待状态，此时不出蒸汽，之后执行步骤二；
步骤二、控制基板通过信号线接受恒温器信号，判断恒温器是否跳开过一次；如果判断结果为否，执行步骤一，如果判断结果为是，则执行步骤三；
步骤三、判断电热盘为已加热至随时可出蒸汽状态，之后执行步骤四；
步骤四、判断是否需要出蒸汽，如果判断结果为否，执行步骤三，如果判断结果为是，则执行步骤五；
步骤五、判断恒温器跳开时间是否超过预先设定的判断值50s，如果判断结果为否，执行步骤四，如果判断结果为是，则判断为无水。
在步骤四中，通过检测蒸汽按键信号，判断是否需要出蒸汽。
本发明的工作原理为：
在锅炉恒温器2后端连接一根信号线3到控制基板1，控制基板1即可判断恒温器是闭合还是跳开。
电熨斗通上电时，水箱中的水通过泵浦连续滴进锅炉底部的电热盘，由于恒温器2是常闭的，锅炉通电持续加热至某一温度，如100℃以上，此时水所产生的蒸汽也被加热至100℃以上，当锅炉温度到达恒温器的工作温度时，恒温器2就将自动第一次跳开，锅炉断电停止加热，温度开始降低，当下降至恒温器的工作温度时，恒温器2又闭合，锅炉又开始加热。如此多次重复，使锅炉温度由恒温器控制在100℃以上。因此当控制基板1通过信号线3检测到恒温器2已跳开一次时，即可判断锅炉底部的电热盘已处于准备完毕状态，可随时出蒸汽。
锅炉处于一个密闭的环境下，与外界的热交换比较差。但是如果有水流进锅炉内的话，水汽化之后会带走相当大的热量，锅炉的温度恢复到工作温度时间就需要一段时间，相应地，恒温器闭合与断开的时间比例就会产生很大的变化。
在本实施例中，锅炉内如果没有水的时候，恒温器闭合的时间约10s、断开的时间约为2min；当有水流进锅炉的话恒温器闭合的时间就会延长至30s以上、断开的时间小于20s。
由于以上几点原理，如果泵浦往锅炉里打水但是锅炉的恒温器却断开50s以上，即可判定为锅炉无水，给锅炉提供水的水箱里里也没有水。
本发明需要的前提是，电热系统一定要是一个相对密闭的系统，与外界的热交换比较单纯，而此系统内的水的汽化是改变热平衡的最重要的变化量。
一种锅炉熨斗，其具有无水检测装置，该装置使用了恒温锅炉的常闭的恒温器以及控制基板，在锅炉恒温器与控制基板之间连接有一根信号线，该控制基板包括一判断单元和一检测单元，该判断单元用于判断恒温器是否断开过一次，如果否，判断为电熨斗通电等待状态，如果是，调用检测单元；该检测单元用于检测恒温器断开时间是否超过预定值，如果是，则判断水箱无水。
本实施例中，该控制基板用于检测获取恒温器信号，并发出指令控制泵浦。
上述的无水检测装置如附图1所示，它包括控制基板1、恒温器2、信号连接线3、泵浦4、加热盘5。本领域人员根据该电路图无需创造性劳动即可设计出具体电路，并应用到电熨斗中，因此在此不进一步描述。
上述仅为本发明的一个具体实施例，但本发明的设计构思并不局限于此，凡利用此构思对本发明进行非实质性的改动，均应属于侵犯本发明保护范围的行为。
本发明锅炉熨斗的无水检测方法、装置及具有该装置的熨斗，通过其信号线将恒温器闭合、跳开判断的情况提供给控制基板，控制基板即可根据实际电加热系统的经验值判断出水箱是否有水，以控制泵浦不会因空抽而损坏，本发明成本及其低廉，且工艺简单，并为熨斗其它部件的设计节省了更多的空间。
