Description

快速水加热装置的防干烧结构及其控制方法 技术领域
本发明涉及一种高功率快速水加热装置，特别是一种快速水加热装置的防干烧结构及其控制方法。
背景技术
目前净/饮水机中常用的水加热方式有内置式热罐。内置式热罐一般由电热丝进行加热，然后通过温控器控制加热的启停。这种加热方式往往存在对水反复加热煮开的问题，一方面反复加热浪费电能，另一方面长期饮用反复加热煮开过的水(“千滚水”)不利于人的身体健康。因此近几年来开始兴起即时加热技术，冷水经过加热管瞬间被加热，只有用水时才加热，不用水时不加热，这就解决了“千滚水”的问题。
一般即时加热器加热功率密度高，一旦干烧，加热器的温度迅速上升，如果不及时切断电源，加热器不可避免地会被烧坏。
现有的一种加热器防干烧方案，在加热器的供电回路里串联1～2个机械式常闭温控器，并把温控器安装在加热器附近。当加热器温度达到设定值时，机械温控器断开，起到保护作用。
技术方案一所述的加热器防干烧方法，由于机械式温控器的反应速度有限，只能适用于加热功率较低的加热器，低功率的加热器其功率密度低，可以干烧相对较长时间而不损坏，为机械温控器的响应争取足够的反应时间。但在快速水加热的需求下，加热器的功率较高，由于功率密度高，温度上升极快，温控器响应不及时，将导致加热器瞬间烧坏。
