摘要:随着中国人生活水平的提高和生活节奏的加快,市场上出现了更多的适合于现代家庭生活的新型家用电器。这些电器都具有高效、节能和环保的特点。中国目前的家用电器产业发展很快,出现了海尔、TCL等国际企业,在一些方面也达到了国际顶尖水平。在家用电器里,彩电和洗衣机的普及率比较高,然而家用洗碗机却一直是一个未开发但拥有极大潜力的领域。究其原因,是因为传统的洗碗机仅采用喷臂式冲洗的清洗结构,不适合中国深度大的碗、盆等餐具的清洗,导致清洗效果差、效率低,耗能大,所以并不受欢迎。根据这些问题,提出将超声波的清洗功能利用在这个领域,设计出高效节能的新型洗碗机。根据超声波清洗的特点和餐具清洗的工艺,在洗碗机整体结构、清洗工艺和控制系统三个方面进行改良设计。结构方面,采用不锈钢清洗槽,合理布置超声波系统,喷臂冲水装置和进排水装置等,使结构更加紧凑合理,提升清洗效果。清洗工艺方面,根据铝锡箔腐蚀法所得的结果,分析洗涤槽内超声波空化强度的分布,选择合适的参数,确定最优的清洗流程。控制系统方面,选取合适的单片机,以各个部分作用的时间先后为逻辑顺序,实现清洗过程的自动化。

Study and design of new-style ultrasonic dishwasher
Abstract: With the improvement of people's living standards and the acceleration of modern life speed, new household electrical equipment which are more adaptable to the modern family life are required to meet customers’ need. These appliances are more efficient, energy-saving and environmentally-friendly. The household appliances industry in China has being developing rapidly. And there appear some international corporations such as Haier, TCL etc. Furthermore, we have reached in top level in some technical fields. Among household appliances, the ration rate of color TV and washing machine are relatively higher, the household dishwasher, however, is an undeveloped but great potential field. The reason is because the traditional dishwasher’s flush cleaning system and spray arm structure are not applicable to the Chinese tableware such as deep bowls, deep pots etc. It was generally regarded as “bad cleaning effect, low efficiency and high energy consumption”, so it was not popular. Now, I try to takes advantage of the cleaning feature of ultrasonic to solve these problems by designing a new efficient dishwasher. According to the characteristics of ultrasonic cleaning and dishwashing’s process, I have improved and redesigned the overall structure of the dishwasher, the cleaning p
