AI Technical Summary
Traditional rice cookers maintain a high temperature even after the heating plate stops working, causing the rice to stick together or burn at the bottom. Also, the rice is still hot and needs to cool down, which makes the heating plate prone to aging and damage.
A heat dissipation water pipe is installed at the bottom of the heating plate. The water circulation system quickly cools the heating plate and the inner pot. The connection between the water tank and the heat dissipation water pipe is controlled by a solenoid valve to form a water circulation to isolate the rice from the bottom of the inner pot, prevent sticking, and accelerate the cooling of the rice.
It effectively prevents rice from sticking or burning at the bottom, shortens the cooling time of rice, extends the service life of the heating plate, and improves the user experience.
