[0047] Preferably, a contact switch 143 is also provided on the mounting plate of the discharging motor 141, and the driving end of the discharging rod 142 is connected to the contact rod 1422. When the contact rod 1422 contacts the contact switch 143, the discharging motor 141 is turned off. When the two are disengaged, the discharging motor 141 starts to output a cycle of rotation, thereby driving the driving rod 142 to rotate to open the discharging cover 30.
[0048] In the cleaning device provided in the embodiment of the present application, rice and water enter from the upper end of the second end 102 of the cleaning bin 10, and driven by the driving motor 24, the stirring rod 22 realizes stirring and cleaning of the rice in the cleaning chamber 10a. After cleaning is completed, the spiral plate 23 pushes the rice and water to move toward the second end 102 of the cleaning bin 10, so that the cleaned rice moves to the discharge port 10d. When the discharge cover plate 30 is opened, the rice falls from the discharge port 10d, and the rice grains that cannot fall naturally are washed away by the water flow of the water inlet 10c or the air flow of the feed port, ensuring that all the cleaned rice falls from the discharge port 10d. This solution fully washes the rice and effectively ensures that the rice can be fully added to the subsequent rice cooker, thereby ensuring the cleaning efficiency and quality and improving the rice adding efficiency.
