摘  要

目前我国人民的生活水平和生活质量显著提高，家用电器也越来越多的进入到人们的日常生活中，为人们的生活带来了诸多便利。洗碗机是自动清洗碗、筷、盘、碟、刀、叉等餐具的设备。在市面上的全自动洗碗机可以分为家用和商用两类，家用全自动洗碗机只适用于家庭，主要有柜式、台式及水槽一体式。然而，家用自动洗碗机在中国却仍有巨大市场潜力需要开发，一方面是因为在中国家用洗碗机发展起步较晚，技术开发不够成熟，不能适应中餐餐具实际生活中需要的洗涤、消毒、烘干等功能。另一方面是自动洗碗机价格昂贵，并且安全性不够高。因此本设计意在设计出一款集洗涤、烘干、消毒功能在内的使用简单、安全高效的家庭自动洗碗机。基于设计和实际使用的需要，本洗碗机在洗涤步骤、自动控制、安全保障等方面做出了创新性设计。

Abstract

At present，the living standards and quality of life of our people have improved remarkably，and more and more household appliances have entered people’s daily lives，bringing convenience to people’s lives. The dishwasher is a device that automatically cleans dishes，chopsticks，plates，dishes，knives，forks，and the like. The fully automatic dishwashers on the market can be divided into two types，household and commercial. The fully automatic household dishwashers are only suitable for families，mainly including cabinets，benches and sinks. However，domestic automatic dishwashers still have huge market potential in China. On the one hand，the development of domestic dishwashers in China is relatively late，and the technology development is not mature enough to meet the needs of washing and disinfection in the actual life of Chinese tableware. drying and other functions. On the other hand，automatic dishwashers are expensive and not sufficiently safe. Therefore，the design is intended to design a home automatic dishwasher that is easy to use，safe and efficient，including washing，drying and disinfecting functions. Based on the design and practical needs，the dishwasher has been innovatively designed for washing steps，automatic control，and safety.
