摘要: 针对商用净水机因内部存水导致细菌滋生和外部环境干扰导致出水菌落总数及致病菌超标问题,分析了UV-LED散热方式、光学性能和流道设计,以及热烘干技术的结构设计对杀菌性能的影响,并通过理论分析和工程实践完成了整机杀菌和抑菌性能改良测试。结果表明:通过改进水力旋流散热结构、光学性能和高辐照度流道,可以有效保证UV-LED流水杀菌有效性;通过新增独立出水流道和缺口设计,可以有效防止外部环境对内部存水造成影响;通过UV-LED与热烘干技术进行联用,有助于保障出水水质安全,满足《生活饮用水水质处理器卫生安全与功能评价规范——反渗透处理装置》标准要求。

Abstract: In response to the problem of excessive bacterial count and pathogenic bacteria in the effluent of commercial water purifiers caused by internal bacterial growth and external environmental interference, focuses on the influence of UV-LED heat dissipation methods, optical performance, and flow channel design, as well as the structural design of radiant illuminance on sterilization performance. Through theoretical analysis and engineering practice, the overall sterilization and antibacterial performance of the machine has been improved. The results show that: by improving the hydraulic cyclone heat dissipation structure, optical performance, and high irradiance flow channel, the effectiveness of UV-LED water flow sterilization can be effectively ensured. By adding independent outlet channels and gap designs, it is possible to effectively prevent external environment from affecting internal water storage. The combination of UV-LED and radiant illuminance helps to ensure the safety of effluent water quality and meets the requirements of the "Sanitary Safety and Functional Evaluation Specification for Drinking Water Quality Treatment Devices - Reverse Osmosis Treatment Devices" standard.
