摘 要
目前我国家电产品普及程度已经相当高,然而,,一方面是由于中国传统手动洗碗习俗的影响,另一方面则是由于传统的洗碗机不能适应中餐餐具的洗涤要求,并且耗能大,安全性不够高,,开发出一款节能环保,安全便宜的家用全自动洗碗机.基于全自动洗碗机的功能要求,这款洗碗机在洗涤工艺、自动控制、安全保障和价格便宜四个方面做出了全新设计.1. 自动控制方面,选择使用AT89C51单片机为控制核心,以各个部件的作用时间为逻辑顺序,实现了洗涤过程的智能化控制;2.洗涤工艺方面,可提供三种不同方式的洗涤,即清洗、标准洗和烘干,使清洗效果达到最佳; 3。安全保障方面,采用漏电检测和看门狗复位电路,,可靠性高,成本低的特点.

Abstract
Now the popularization of our electrical household products has already reached to quite high degree. However, the field of home dishwasher has had enormous market potential but undeveloped field all the time。 It is mainly because the traditional dishwasher products can’t meet the needs of washing of Chinese tableware, energy consumption is great and provide lessly safty 。 Aimed at these problems, an ultrasonic dishwasher with energy—conservation and environmental protection was encouraged to research and develop。with the function of automatic dishwasher,a bran—new design is made in three aspects of the dishwasher: washing technique,automatic control and Security。 1。 In the aspect of automatic control,AT89C51 is chosen as the core of the control and the working time of every assembly unit is used as logic order。So the intellectualized control of washing process is realized; the aspect of cleaning technique,these can supply there washing methods,washing, standard washing and dring to make the cleaning effect best; 3。In the aspect of Security,We uesd creepage detecting and watchdog rest circuit to ensure safety demands adequately。 This control system has simple structure,high dependability,and low costs。
