摘要
在现代快节奏生活中，便捷高效的家居清洁设备成为提升生活品质的重要需求。传统洗碗机存在清洗流程固定、水位与温度控制精度不足、无法根据污渍程度动态调整清洗策略等问题，难以满足用户对节能、洁净及智能化的需求。因此，研发一款具备自动流程控制、多参数监测与远程交互功能的智能洗碗机具有重要现实意义。
本设计提出了一种基于 STM32F103C8T6 单片机的智能洗碗机。系统主要功能包括：按预设流程自动完成加水（继电器控制）、加洗涤剂（3s）、清洗（10s）、排水、二次清洗（10s）、排水、加热烘干、消毒（5s）及结束声光报警（3 声）全流程；通过 YW01 液位检测模块实时监测液位，加水时水位达最大值后停止，排水时水位为 0 后停止；借助防水式 DS18B20 检测温度，加热烘干至温度超最大值时停止；通过 TSW-30 浑浊度模块监测水质，第二次清洗后若浑浊度超最大值则继续清洗排水；用户可通过按键设置各流程时间与阈值，控制清洗启停及直接结束；OLED 显示屏实时显示总剩余时间、清洗步骤及测量数据；通过 ECDO2 蓝牙模块与手机连接，实现数据同步、手机端阈值设置及远程控制启停。
该智能洗碗机的作用在于，通过智能化流程控制与多参数监测，实现了清洗过程的精准化与自动化。动态调整清洗策略提升了餐具洁净度，液位与温度的精准控制降低了能耗，远程交互功能增强了使用便捷性。为用户提供了高效、节能、智能的家居清洁解决方案，有效提升了生活便捷度与家居体验。

Abstract
In modern fast-paced life, convenient and efficient home cleaning equipment has become an important demand for improving the quality of life. Traditional dishwashers suffer from fixed cleaning processes, insufficient precision in water level and temperature control, and the inability to dynamically adjust cleaning strategies based on the degree of stains, making it difficult to meet users’ demands for energy efficiency, cleanliness, and intelligence. Therefore, developing an intelligent dishwasher with automatic process control, multi parameter monitoring, and remote interaction functions is of great practical significance.
This design proposes an intelligent dishwasher based on STM32F103C8T6 microcontroller. The main functions of the system include: automatically completing the entire process of adding water (relay control), detergent (3s), cleaning (10s), drainage, secondary cleaning (10s), drainage, heating and drying, disinfection (5s), and ending the sound and light alarm (3s) according to the preset process; Real time monitoring of liquid level through YW01 liquid level detection module, stopping when the water level reaches the maximum value during water addition, and stopping when the water level reaches 0 during drainage; Use waterproof DS18B20 to detect temperature, and stop heating and drying when the temperature exceeds the maximum value; Monitor water quality through the TSW-30 turbidity module. If the turbidity exceeds the maximum value after the second cleaning, continue to clean the drainage; Users can set the time and threshold for each process by pressing buttons, control the start stop and direct end of cleaning; OLED display screen displays real-time total remaining time, cleaning steps, and measurement data; Connect to the mobile phone through ECDO2 Bluetooth module to achieve data synchronization, mobile threshold setting, and remote control of start stop.
The function of this intelligent dishwasher is to achieve precision and automation of the cleaning process through intelligent process control and multi parameter monitoring. The dynamic adjustment of cleaning strategies has improved the cleanliness of tableware, the precise control of liquid level and temperature has reduced energy consumption, and the remote interaction function has enhanced the convenience of use. We provide users with efficient, energy-saving, and intelligent home cleaning solutions, effectively improving the convenience of life and home experience.
