@Joe.wang I was not trying to insult you, I was simply asking for clarification. You still have not provided enough additional information for someone to assist you. If this is in-fact a rice cooker that you install as a permanent fixture in your home, I think it is a good fit for this website as "Installation, maintenance, and repair of major appliances." If this is a rice cooker that you plug into a wall, then it is off-topic for this website. Regardless, you will need to provide information about the other wires that you would like to connect to the rice cooker in order to supply power. —
