With the improvement of living standards, people pay more attention to diet and health issues. Currently, most electric rice cookers are non-stick pots with coatings on the inner liner. With the increase in use, there is a risk of coating peeling off, and the coating itself is not healthy and environmentally friendly. This project aims to design an innovative non-coating cast iron electric rice cooker, which combines the advantages of cast iron materials with modern technological innovations to bring users a better cooking experience. We are committed to designing a durable, reliable, healthy and energy-saving electric rice cooker to provide users with a more healthy cooking solution.
