One end of the transmission member 5 is in transmission connection with the output shaft 41, and the other end is in rotational connection with one end of the transmission rod 6. The other end of the transmission rod 6 extends into the interior of the rice bin 1 and is connected with the stirring mechanism. The transmission rod 6 is connected with the partition disc 2. Specifically, the side wall of the transmission rod 6 is provided with a spline 61. The middle part of the partition disc 2 is provided with a second through hole. The hole wall of the second through hole is provided with a spline groove 22. The spline 61 is in meshing transmission with the spline groove 22.

[0047] Specifically, the output shaft 41 is a character-shaped shaft. The bottom wall of the transmission member 5 is provided with a character-shaped groove. The output shaft 41 is inserted into the character-shaped groove so that the output shaft 41 can drive the transmission member 5 to rotate together.

The stirring paddle 7 includes a stirring paddle body and blades provided on the stirring paddle body. The transmission rod 6 is in transmission connection with the stirring paddle body. The transmission rod 6 drives the stirring paddle body to rotate, so that the blades rotate to stir the rice in the rice bin 1.

[0053] Optionally, a control panel of the cooking device is provided with a rice discharging control button, and the amount of rice discharging can be adjusted. In a specific embodiment, the amount of rice discharging on the control panel can be selected as 1, 2, 3, 4, 5, 6, 7 or 8, which corresponds to the number of metering cavities 21 for discharging rice this time, and the metering cavities 21 rotate in a circular manner. After one metering cavity 21 rotates to the position directly above the discharging channel 31 to discharge rice, it continues to rotate, and when it rotates to the position directly below the discharging opening 11, the metering cavity 21 is filled with rice again to wait for the next rotation to the position directly above the discharging channel 31 for the next time of discharging rice.
