Abstract: In recent years, with the diversified development of diet, people's health awareness has been improved. The electric steam oven that keep the true taste and retain the original fresh nutrition enter thousands of households. When the user cooks, the steam condenses to form a large amount of residual water at the bottom of the inner cavity, which is easy to breed bacteria for a long time and has adverse effects on health. Through innovative design more than cooking water automatic recovery mechanism, main design system with filtration system, prevent return flavour and configuration professional pump drainage system, and building model functional prototypes, design the program logic to the residual water discharge of intelligent control, and built the model functional prototype, designed the program logic to control the discharge of surplus water intelligently, and carried out comparative verification and testing on the cooking of food materials with no surplus water, and innovatively formed the intelligent control of surplus water technology and intelligent cooking system equipment. The results show that the application of the intelligent control of residual water technology in the steaming oven not only effectively prevents the residual water containing cooking impurities from evaporating again and causing the taste of food materials, ensuring the quality of healthy and fresh steaming, but also solve the difficulty of manual cleaning of residual water, improve user experience satisfaction and reputation, and promote the green and healthy development of intelligent kitchen electric market.
