快热式电热水器控制系统设计(含CAD图)(论文说明书14000字,外文翻译,CAD图7张)
摘 要
随着生活的加快,快热式电热水器省时的特性越来越被生活在忙碌的人群所接受,随着用电环境的改善,即催生了快热式电热水器的快速增长。它体积小,重量轻,要使用热水时即开即用,无需等待,省去了加热多用的热水,因此它具有省时,省电,省水的优点,由于以上原因,快热式电热水器在以后有着极为广阔的发展前景。本设计采用AT89C51作为核心控制器,铺以按键,显示电路,利用温度传感器DS18B20检测出水口温度,采用双向可控硅控制,单片机通过光耦合器给可控硅触发信号,控制可控硅的导通角,从而控制电热丝的有效加热功率。

Design of Fast Heat Electric Water Heater Control System
Abstract
As life speeding up ,the characteristics of electric water heater Fast heat save more and more acceptable to the crowd of a busy life .It has small size ,light weight, and then you can use the hot water without any wait, therefore if has save water heater in later has a very broad development prospects .The design USES AT89C51 as the detection, the outlet temperature by bidirectional thrusters controlled by single chip computer controlled light coupler to triggered signals, control silicon controlled conduction Angle, so as to control the resistance wire effective heating power .
