基于单片机的恒温水龙头设计

Design for Fixed Temperature Faucet Based on Single Chip Computer

介绍了基于单片机的恒温水龙头的设计方法。针对传统冷热双联式水龙头手动调节水温,不能实现出水温度的精确控制等缺点,将单片机作为智能控制器应用于水龙头中。利用单片机检测DS18B20采集到的水温,经过分析计算可控制冷热水入水比例,通过循环水系统将混水过程中未达温度的水重新注入加热装置的入水口,实现重复利用。该系统实现了双联式水龙头的精确调温,保证恒温用水的同时实现了高效节水,适用于各种恒温用水的场合,具有较高的应用价值。

A design method of the constant temperature faucet based on single chip computer is introduced. Aimion at traditional duplex- style hot and cold taps to manually adjust the water temperature,the equipment uses single chip computer to detect water temperature by DS18B20. It controls the proportion of hot and cold water via analysis and calculating, the lower temperature water is injected heating device inlet in order to realize repeat utilization through the troubled waters of recycled water system. A double- precision thermostat faucet is realized,constant water temperature and a highly efficient water- saving are ensured simultaneously. This machine is suitable for a variety of occasions of constant water temperature, it has a high application value.
