As shown in Figures 1, 2, and 4, a rice cooking device provided by some embodiments of the present application includes a rice cooking main body 10 and an outer row assembly 20. The rice cooking main body 10 is provided with a rice cooking cavity 11, and the outer row assembly 20 is installed. On the upper part of the rice cooking main body 10, the outer row assembly 20 includes an inner row tube 21 and an outer row tube 22 that communicate with each other. The inner row tube 21 is located inside the rice cooking cavity 11, and the end of the inner row tube 21 extends downward and is used for insertion In the rice soup, the outer drain tube 22 is located outside the rice cooking cavity 11 and is used to guide the rice soup to be discharged outward.

In the rice cooking device provided by the embodiment of the present application, when cooking rice, the user successively adds an appropriate amount of rice and water as needed into the rice cooking cavity 11, so that the inner drain tube 21 is inserted downward into a certain depth of the water (the The depth position is controlled at the depth of the amount of water required to cook the rice), and then the rice cooking body 10 is made to work to cook the rice. During the cooking process, the water is heated and gradually boils to release water vapor, and the water is in the rice cooking cavity. Rice soup is gradually formed in 11, and since the inner drain tube 21 is inserted under the surface of the rice soup at this time, water vapor cannot be discharged outwards at this time, and a relatively large air pressure is accumulated in the rice cooking cavity 11, and this air pressure acts on the surface of the rice soup surface. The rice soup is compressed and discharged through the inner tube 21 and the outer tube 22 to drain the excess rice soup in the rice cooking cavity 11 to obtain low-glycation rice. In addition, since the inner row tube 21 is located at the upper part of the rice cooking body 10, the rice grains contained in the rice soup will naturally fall due to its own weight during the process of discharging the rice soup.
