[0003] With the increasingly fast pace of modern life, the automation of cooking appliances is gradually becoming the mainstream trend in the industry. For example, rice cookers have been transformed from ordinary rice cookers to fully automated ones.

[0004] In related technologies, automatic rice cookers mainly achieve rice washing through internal or external methods. For example, after washing rice inside the cooker, some impurities will be generated. These impurities are stored inside the rice cooker and are not easily discharged. After washing rice outside the cooker, during the process of transferring the rice to the inside, some rice will stick to the transmission tube, affecting the flow of the tube. Users need to disassemble and clean the tube multiple times, which is very inconvenient for users. Summary of the Invention
