[0030] In this embodiment, the rice storage hopper 3 is equipped with a material level sensor 21 and a vibrating feeder 22 at the bottom, and the rice preparation container 5 is equipped with a second weight sensor 23.

[0031] By adopting the above technical solution, the material level sensor 21 on the rice storage hopper 3 detects the amount of rice in real time, and the second weight sensor 23 on the rice preparation container 5 detects the amount of rice in real time. When the amount of rice reaches the preset value, the vibrating feeder 22 is controlled to stop feeding.

[0032] In this embodiment, the rice washing cylinder 6 is provided with a chute 24 above it, and the upper end of the chute 24 is aligned with the discharge port at the bottom of the rice preparation container 5.

[0033] By adopting the above technical solution, the baffle gate 25 at the bottom of the rice preheater 5 is opened, and the rice enters the rice washing cylinder 6 through the chute 24, ensuring that the rice smoothly enters the rice washing cylinder 6 from the rice preheater 5, avoiding spillage and loss of rice, and ensuring the smooth progress of the rice washing work.

[0034] In this embodiment, the bottom of the preparatory rice dissolving device 5 and the feeding hopper 2 are both provided with a material blocking gate 25, and the cabinet 1 is provided with an opening and closing cylinder 26 for driving the material blocking gate 25 to move.

[0035] By adopting the above technical solution, the material blocking gate 25 at the bottom of the feed hopper 2 and the preparatory rice dissolving tank 5 is driven by the opening and closing cylinder 26.

[0039] In this embodiment, the cabinet 1 is further configured to have an improver storage box 32, and the improver in the improver storage box 32 can be transported to the inner pot liner 11 by a delivery pump to realize the automatic addition of the improver.

[0040] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0041] Example: Before starting the rice washing machine, rice is added to the feeding hopper 2. The motor 16 of the unloading lifting assembly is started. The motor 16 drives the drive sprocket 17 to rotate, which drives the driven sprocket 18 and the axle to rotate through the transmission chain. This causes the chain 13 and the feeding bucket 14 to rotate in a cycle, conveying the rice in the feeding hopper 2 to the rice storage hopper 3. The level sensor 21 on the rice storage hopper 3 detects the amount of rice in real time. When the amount of rice in the rice storage hopper 3 reaches the preset amount, the level sensor 21 sends a signal, and the unloading lifting assembly automatically stops working. When the amount of rice in the rice storage hopper 3 is low, the level sensor 21 sends a signal, and the unloading lifting assembly automatically starts to add rice.

[0042] When the automatic rice washing mode is turned on, the inner pot 11 is placed in the work station. The first weight sensor 10 detects the weight of the pot, and the rice washing mechanism at the corresponding work station starts working automatically. The vibrating feeder 22 at the bottom of the rice storage hopper 3 is started, and the rice is vibrated and conveyed to the pre-rice melting tank 5. The weight sensor on the pre-rice melting tank 5 detects the amount of rice in real time. When the amount of rice reaches the preset value, the vibrating feeder 22 stops automatically, and the baffle gate 25 at the bottom of the pre-rice melting tank 5 opens. The rice enters the rice washing cylinder 6 through the chute 24. At the same time, the nozzle 8 on the water inlet pipe 7 is turned on, and the high-pressure fan-shaped nozzle 8 sprays water to wash the rice. The spraying time is automatically controlled by the program. When the water is full to the upper drain outlet, the upper water surface is discharged from the upper drain outlet. After the spraying time is over, the remaining water in the tank is discharged from the lower drain outlet.

[0043] After rinsing, the flip cylinder 20 at the bottom of the rice washing cylinder 6 is activated, opening the flip cover 19. The rinsed rice enters the inner pot 11. According to the preset weight ratio of rice to water, water and oil are added to the inner pot 11. When the preset amount of water required for cooking rice is reached, water addition stops, and the lower cover of the rice washing cylinder 6 is automatically closed. At this time, the rice rinsing work is completed. The operator takes out the pot that has completed the rinsing work, puts in an empty pot, and the rice washing machine automatically repeats the above rice rinsing operation.
