Abstract: Performance improvement is always a key breakthrough direction for dishwasher research and development, and it is also one of the main demands of users. Firstly, based on the spray washing technology of dishwashers and the rapid heating characteristics of steam, it is introduced that a steam generator module is added to the dishwasher and the washing concept of dishwasher steam-water mixing washing is proposed. Secondly, the temperature rise data of different test points at inner chamber during different time periods is obtained through prototype test and integrated with the washing characteristics of dishwasher, then it develops a steam using way to improve the washing and drying effect for dinnerware, and also conducts relevant verification experiments. Finally, the applications of steam-water mixing washing technology in other areas such as rapid washing and drying are discussed. Aim to improve the dishwasher performance by combining traditional spray washing and steam washing, the steam-water mixing washing technology is proposed, providing the ideas of the application of this technology in dishwashers.
