具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合实施例及附图，对本发明进行进一步详细说明。
如图1、图2所示，其为本人于2010年04月13日申请、申请号为：201010150829.1[申请名称为：汽水分离器及蒸汽发生装置]的中国发明专利。本发明专利申请是在上述技术的基础上所做出的进一步改进，目的是解决当出水口9处形成水封时，蒸汽发生装置中发热管6产生干烧的问题。
为了简化实施例，在以下具体实施例中，将蒸汽发生装置设置在家用电蒸箱中，对家用电蒸箱进行描述。
具体实施例一
如图9、图10所示，该家用电蒸箱包括外壳19、蒸室18、蒸汽发生装置17，所述蒸室18、所述蒸汽发生装置17设置在所述外壳19内，处于工作状态（所述蒸室18的门关闭）时，所述蒸室18与所述蒸汽发生装置17通过管道Ⅴ12相连通形成密封体。
如图3所示，所述蒸汽发生装置包括水箱1、包括密封盖41和底座42的汽水分离器4、分水阀5、三根发热管6。如图4所示，所述密封盖41盖在所述底座42的顶端形成腔体412。如图7a所示，所述密封盖包括挡板Ⅰ410、导向弧411。如图7b所示，所述底座42包括回流管421、连接座管422、三个连接座424、挡板Ⅱ425、出汽接口426。所述底座42的底面向下凹有呈漏斗形的空腔4203，所述空腔4203在所述导向弧411的导向方向上与所述连接座424并排设置，所述空腔4203包括底平面420和底斜面423。所述底平面420和所述底斜面423靠近所述回流管421，所述回流管421设在所述底座42的外侧壁上并与所述空腔4203的底平面420对应设置。所述挡板Ⅰ410和所述挡板Ⅱ425上下对应设置将所述腔体412分成左腔室4121和右腔室4122，所述出汽接口426和所述连接座424分别与所述左腔室4121和所述右腔室4122相连通。所述挡板Ⅰ410和所述挡板Ⅱ425上下对应位置开有切口，所述切口设置在远离所述连接座424和所述出汽接口426的一端，所述连接座424和所述出汽接口426通过该切口相连通，所述底平面420上设置有所述连接座管422。
所述汽水分离器4和所述分水阀5之间设置有拉杆16，所述拉杆16将所述汽水分离器4和所述分水阀5连接为一体，还起支撑所述汽水分离器4的作用，防止所述发热管6受压，延长所述蒸汽发生装置17的寿命。所述发热管6设置在所述连接座424和所述分水阀5之间。所述出汽接口426上连接有通往所述蒸室18的所述管道Ⅴ12。所述水箱1与所述汽水分离器4相对的一侧面上的上端和下端分别设置有回流口3、出水口9，所述回流口3处设置有位置阀Ⅰ2，所述位置阀Ⅰ2上设置有弹簧，所述出水口9处设置有位置阀Ⅱ10，与所述位置阀Ⅱ10对应位置设置有位置阀Ⅲ8，所述位置阀Ⅲ8设置在管道Ⅳ15中，所述位置阀Ⅱ10和所述位置阀Ⅲ8均设置有弹簧。所述回流口3和所述回流管421相连通，所述出水口9和所述分水阀6通过所述管道Ⅳ15相连通，所述连接座管422和所述管道Ⅳ15通过管道Ⅰ7相连通（注所述管道Ⅰ7和所述管道Ⅳ15还可以设置成一根管道）。所述管道Ⅳ15和所述管道Ⅰ7相连通的位置越接近所述出水口9越好。
该实施例的工作原理和过程是：在所述水箱1中加满水后，将所述水箱1推入至工作位置，所述位置阀Ⅰ2、所述位置阀Ⅱ10、所述位置阀Ⅲ8在弹簧力的作用下离开原来的位置，使所述回流口3和所述出水口9处于常开状态。此时所述水箱1中的水先后经过所述出水口9和所述管道Ⅳ15先后流入所述分水阀5和所述加热管6中，设置好功能时间、接通电源，所述加热管6即开始工作。所述加热管6将水加热，一方面产生蒸汽，蒸汽经过所述连接座424进入所述右腔室4122，再通过所述切口进入所述左腔室4121，再经过所述出汽接口426通过所述管道Ⅴ12进入所述蒸室18；另一方面产生热水，热水沸腾时，一部分热水会经过所述连接座424进入所述右腔室4122，其中一部分会经过所述连接座管422先后通过所述管道Ⅰ7和所述管道Ⅳ15再次进入所述分水阀5，另一部分会经过所述回流管421通过所述回流口3进入所述水箱1中。
该例中由于所述汽水分离器4通过所述管道Ⅰ7与所述管道Ⅳ15相连通，这样设置能防止所述出水口9处水封现象的产生，起到防干烧的作用，同时也加快所述汽水分离器4中水的回流。
当所述水箱1中没有水或水量不足时，检测水位的装置即会发出信号，执行报警并同时切断所述蒸汽发生装置17中的电源，使所述蒸箱停止工作。
具体实施例二
如图5、图7c所述，该实施例相对于实施例一中的方案，主要区别在于所述连接座管422设置在所述底斜面423上，所述连接座管422和所述管道Ⅳ15通过管道Ⅲ14相连通（注所述管道Ⅲ14和所述管道Ⅳ15还可以设置成一根管道）。所述管道Ⅳ15和所述管道Ⅲ14相连通的位置越接近所述出水口9越好。
该实施例的工作原理和过程与实施例二的区别是：所述加热管6将水加热，一方面产生蒸汽，蒸汽经过所述连接座424进入所述右腔室4122，再通过所述切口进入所述左腔室4121，再经过所述出汽接口426通过所述管道Ⅴ12进入所述蒸室18；另一方面产生热水，热水沸腾时，一部分热水会经过所述连接座424进入所述右腔室4122，其中一部分会经过所述连接座管422先后通过所述管道Ⅲ14和所述管道Ⅳ15再次进入所述分水阀5，另一部分会经过所述回流管421通过所述回流口3进入所述水箱1中。
该例中由于所述汽水分离器4通过所述管道Ⅳ15与所述管道Ⅲ14相连通，这样设置能防止所述出水口9处水封现象的产生，起到防干烧的作用，同时也加快所述汽水分离器4中水的回流。
具体实施例三
如图6、图7d所述，该实施例相对于实施例一、二中的方案，主要区别在于所述底座不包括所述连接座管422，所述管道Ⅴ12上分接有管道Ⅱ13（注所述管道Ⅱ13和所述管道Ⅴ12还可以设置成一根管道），所述管道Ⅱ13与所述管道Ⅳ15相连通（注所述管道Ⅱ13和所述管道Ⅳ15还可以设置成一根管道）。所述管道Ⅱ13可以设置在所述管道Ⅴ12上任何位置，越接近所述蒸室18的位置越好。
该实施例的工作原理和过程与实施例一、二的区别是：所述加热管6将水加热，一方面产生蒸汽，蒸汽经过所述连接座424进入所述右腔室4122，再通过所述切口进入所述左腔室4121，再经过所述出汽接口426通过所述管道Ⅴ12进入所述蒸室18，蒸汽在所述管道Ⅴ12中由于冷凝而产生的水珠，先后经过所述管道Ⅱ13和所述管道Ⅳ15再次进入所述分水阀5；另一方面产生热水，热水沸腾时，一部分热水会经过所述连接座424进入所述右腔室4122，再经过所述回流管421通过所述回流口3进入所述水箱1中。
该例中由于所述汽水分离器4通过所述管道Ⅱ13与所述管道Ⅳ15相连通，这样设置能防止所述出水口9处水封现象的产生，起到防干烧的作用，同时由于所述管道Ⅱ13的设置，使进入所述蒸室18中的蒸汽饱和度更高，也使得冷凝的水珠流回到所述分水阀5而被再次利用，起到节约水资源的作用。
具体实施例四
该实施例相对于实施例一、二、三中的方案，主要区别在于该实施例是实施例一和实施例三的组合，即所述底平面420上设置有所述连接座管422，所述连接座管422和所述管道Ⅳ15通过所述管道Ⅰ7相连通，所述管道Ⅴ12上又分接有所述管道Ⅱ13（注所述管道Ⅳ15、所述管道Ⅰ7、所述管道Ⅲ3还可以设置为一根管道）。或者实施例二和实施例三的组合，即所述底斜面423上设置有所述连接座管422，所述连接座管422和所述管道Ⅳ15通过所述管道Ⅲ14相连通，所述管道Ⅴ12上又分接有所述管道Ⅱ13（注所述管道Ⅳ15、所述管道Ⅲ14、所述管道Ⅱ13还可以设置为一根管道）。
该实施例的工作原理和过程与实施例一、二、三的区别是：所述加热管5将水加热，一方面产生蒸汽，蒸汽经过所述连接座424进入所述右腔室4122，再通过所述切口进入所述左腔室4121，再经过所述出汽接口426通过所述管道Ⅴ12进入所述蒸室18，蒸汽在所述管道Ⅴ12中由于冷凝而产生的水珠，先后经过所述管道Ⅱ13和所述管道Ⅳ15再次进入所述分水阀5；另一方面产生热水，热水沸腾时，一部分热水会经过所述连接座424进入所述右腔室4122，其中一部分会经过所述连接座管422先后通过所述管道Ⅰ7（施例一和实施例三的组合）或者所述管道Ⅲ14（实施例二和实施例三的组合）和所述管道Ⅳ15再次进入所述分水阀5，另一部分会经过所述回流管421通过所述回流口3进入所述水箱1中。
该例中由于所述汽水分离器4通过所述管道Ⅰ7（施例一和实施例三的组合）或者所述管道Ⅲ14（实施例二和实施例三的组合）以及所述管道Ⅱ13与所述管道Ⅳ15相连通，这样设置能防止所述出水口9处水封现象的产生，起到防干烧的作用，同时由于所述管道Ⅱ13的设置，使进入所述蒸室18中的蒸汽饱和度更高，也使得冷凝的水珠流回到所述分水阀5而被再次利用，起到节约水资源的作用。
具体实施例五
如图8a所示，所述蒸汽发生装置区别于实施例一、二、三、四的是所述水箱1内靠近所述汽水分离器4的一侧面上设置有回流罩11，所述回流罩11将所述水箱1隔成两个腔室，所述回流口3设置在所述回流罩11内，所述回流罩11的下端与所述出水口9平齐处设置有开口，所述两个腔室通过所述开口相连通，所述回流罩11的上端面设置有连通所述两个腔室的切口Ⅰ110。
该实施例的工作原理和过程区别于实施例一、二、三、四的是：经过所述回流管421的那部分热水进入了所述回流罩11中，与所述水箱1中的冷水隔离开，有效的防止了热量的大量散失，起到节能的作用。所述切口Ⅰ110的设置可以使水箱两个腔室的气压相等，不致出现所述汽水分离器4中的气压过大，防止干烧现象的产生。
具体实施例六
如图8b所示，所述蒸汽发生装置区别于实施例五的是：隔板111替换了所述回流罩11。所述隔板111将所述水箱1隔成两个腔室，所述隔板111下端设置有连通两个腔室的开口，所述隔板111上端设置有连通所述两个腔室的切口Ⅱ1110。
