基于AT89C51单片机的新型电水瓶电路设计与分析

A new type of electric bottle circuit design and analysis based on AT89C51

针对市场上出售的普通电热水瓶瓶内水量过少干烧断保险、维修次数频繁的情况,设计了一种新型的控制电路,界面友好,操作人性化,可以实时显示水温,设置开水的保温温度,具有防倾倒功能,避免意外烫伤;当瓶内水量过少可自动断电防干烧,延长电热水瓶使用寿命。

Based on the market sale of ordinary electric bottle too little water in bottle dry burn out insurance,the maintenance of frequent situation,design a new kind of control circuit,friendly interface,humanized operation,and can be real- time display temperature,set the heat preservation temperature of hot water. The system has the function of anti dumping,avoid accidental burns. When too little water in the bottle can automatically prevent dry,power protection,the extension service life.
