Specifically, the first driving device 21 drives the first transmission device to act, and the first transmission device drives the feeding bin 16 to move upwards to the third position, as shown in fig. 4. Wherein the third position is located between the storage position and the mating position. When in the third position, the feed bin 16 is not in communication with the outlet 14 of the storage bin 13 and the feed inlet 7 of the washing bin assembly 5. By setting the third position, the scheme can divide the stroke of the up-and-down movement of the transmission shaft 26 into a section to the feed bin 16, so that the movement stroke of the transmission shaft 26 can be reduced, and the transmission shaft 26 is prevented from being overlong.
When a material washing operation is intended, as shown in fig. 5, 13 and 14, the control unit controls the third driving device 28 to act, the third driving device 28 can drive the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, the second gear 30 drives the driving screw 31 to move downwards, and the driving screw 31 is sleeved outside the driving shaft 26, so that the driving shaft 26 moves downwards along with the driving screw 31 to be engaged with the connecting shaft 27 of the material washing bin assembly 5. At this time, the control unit controls the second driving device 24 to act, so that the second driving device 24 drives the transmission shaft 26 to rotate, and the transmission shaft 26 can drive the connecting shaft 27 to rotate. When the connection shaft 27 is rotated, the rotation shaft 33 engaged with the connection shaft 27 and the stirring member 19 can be rotated, so that a washing operation can be performed. The material washing cavity is provided with materials and water, and the materials and the water are stirred together under the drive of the stirring piece 19. It will be appreciated that the washing silo cover 17 is in a closed position, i.e. above the drain 9, when the washing operation is performed.
When the washing operation is completed and the draining is intended, the control unit controls the washing bin cover 17 to move to the communicating position so that the drain port communicates with the washing chamber. Specifically, the control unit controls the third driving device 28 to act so that it drives the drive screw 31 to move downward, and the drive screw 31 pushes the rotation shaft 33 to move downward, so that the stirring member 19 can be moved downward. When the stirring member 19 moves down to the communicating position where the washing chamber cover 17 moves to the lower side of the drain port 9, as shown in fig. 6, the third driving means 28 is controlled to stop the operation, and at this time, the sewage in the washing chamber can flow to the drain pipe 10 and the sewage tank 48 through the drain port 9. It will be appreciated that in other embodiments, the draining operation may be performed while the washing operation is performed, i.e., while the washing operation is performed, and the water intake operation may be performed while the washing operation is performed.
When the drainage is completed and the discharging operation is intended, the control unit controls the washing bin cover 17 to move to the open position. Specifically, the control unit controls the third driving means 28 to be turned on so that it drives the drive screw 31 to continue to move downwards, and the drive screw 31 pushes the rotating shaft 33 downwards, so that the stirring member 19 can be moved downwards to leave the washing chamber, as shown in fig. 7. When the stirring piece 19 moves downwards to leave the material washing cavity, the third driving device 28 is controlled to stop acting, and the control unit controls the second driving device 24 to be opened, so that the stirring piece 19 can be driven to rotate, and washed rice is thrown into the inner pot 3.
After or while throwing the rice into the inner pot, the control unit may control the water pump of the water inlet assembly to be turned on, so that water in the clean water tank is introduced into the wash chamber via the water inlet line 99 and flows into the inner pot via the wash chamber to be ready for cooking.
After the blanking operation is completed, the third driving device 28 may drive the drive screw 31 to move upward, and after the drive screw 31 moves upward into the feed bin 16, the first driving device 21 may drive the feed bin 16 to return to the storage position. At this time, the rotation shaft 33 and the stirring member 19 connected thereto may be returned upward to the original position by the elastic member 40.
According to the cooking utensil 1 of the embodiment, the inner pot 3, the pot cover 4, the washing bin assembly 5, the clean water tank 81 and the sewage tank 48 can be easily detached for washing, so that the cleaning process of the whole cooking utensil 1 is simplified.
