In one embodiment, the cooking appliance further comprises a control unit, and the control unit can be coupled with the first driving device, the second driving device, the third driving device and the water pump to control the actions of the above components.

In a preferred embodiment, the electric parts (such as the motor, the heating device, the temperature measuring device and the like) in the cooking utensil are all arranged on the machine body and the pot body, so that the pot cover has no electric parts, the pot cover can be manufactured without considering water resistance and can be cleaned more conveniently, when the pot cover is detachable from the pot body, the pot cover can be detached and cleaned independently, and the pot cover can be washed under a tap or cleaned in a basin due to the fact that the pot cover has no electric parts. Or the charged parts are all arranged on the machine body, so that the pot cover and the pot body have no charged parts. The pot cover and the pot body are both provided with no electrified part, so that the whole body does not need to consider water resistance, and even the pot cover and the pot body can be placed under a water tap for washing.

The whole working process and control method of the cooking appliance 1 according to the preferred embodiment are described below with reference to fig. 2-7:

as shown in fig. 2, the cooking appliance 1 is in an initial state. At the moment, the feeding bin 16 is in the storage position, the feeding bin 16 is not communicated with the outlet 14 of the storage bin 13 and the feeding port 7 of the washing bin assembly 5, and the washing bin cover 17 is in the closing position.

When the blanking operation is intended, the control unit controls the feeding mechanism to move to the mating position. Specifically, the control unit controls the first driving device 21 to act, and the first driving device 21 can drive the first transmission device to act, so that the first transmission device can drive the feeding bin 16 to move downwards to the matching position. As shown in fig. 3, the cooking appliance 1 is in a blanking state. At this time, the feeding bin 16 is at the matching position, and the feeding bin 16 is communicated with the outlet 14 of the storage bin 13 and the feeding port 7. When in the discharging state, the feeding hole 88 can be communicated with the outlet 14 of the storage bin 13, and the discharging hole 82 can be communicated with the feeding hole 7 of the washing bin assembly 5, so that the material in the storage bin 13 enters the feeding bin 16 through the feeding hole 88 and then enters the washing bin assembly 5 through the discharging hole 82. The amount of rice flowing into the washing chamber can be calculated by time.

After the blanking operation is completed or simultaneously with the blanking operation, the control unit may control the water pump of the water inlet assembly to be turned on, so as to introduce water in the clean water tank into the washing bin body via the water inlet line 99 to prepare for the washing operation.

When the blanking operation and the launching operation are completed, the control unit controls the feeding mechanism to return to the third position. Specifically, the first driving device 21 drives the first transmission device to move, and the first transmission device drives the feeding bin 16 to move upward to the third position, as shown in fig. 4. Wherein the third position is 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 wash bin assembly 5. According to the scheme, the third position is arranged, so that the stroke of the up-and-down movement of the transmission shaft 26 can be divided into sections to the feeding bin 16, the movement stroke of the transmission shaft 26 can be reduced, and the phenomenon that the transmission shaft 26 is too long is avoided.

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 transmission screw 31 to move downwards, and the transmission shaft 26 also moves downwards along with the transmission screw 31 to be engaged with the connecting shaft 27 of the material washing bin assembly 5 because the transmission screw 31 is sleeved outside the transmission shaft 26. 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 connecting shaft 27 is rotated, the rotating shaft 33 engaged with the connecting shaft 27 and the stirring piece 19 may be rotated, so that the washing operation may be performed. The material washing cavity is filled with materials and water, and the materials and the water are stirred together under the driving of the stirring piece 19. It will be appreciated that the washing stock cover 17 is in a closed position, i.e. above the discharge opening 9, during the washing operation.

When the washing operation is completed and drainage is intended, the control unit controls the washing bin cover 17 to move to the communication position, so that the drain outlet is communicated with the washing cavity. Specifically, the control unit controls the third driving device 28 to operate, so that the third driving device drives the transmission screw 31 to move downwards, and the transmission screw 31 pushes the rotating shaft 33 to move downwards, so that the stirring piece 19 can be moved downwards. When the stirring element 19 moves downwards to the communicating position where the washing bin cover 17 moves below the sewage discharge outlet 9, as shown in fig. 6, the third driving device 28 is controlled to stop, and the sewage in the washing cavity can flow to the sewage discharge pipeline 10 and the sewage tank 48 through the sewage discharge outlet 9.

When the draining is completed and the blanking operation is intended, the control unit controls the washing bin cover 17 to move to the open position. Specifically, the control unit controls to open the third driving device 28, so that the third driving device drives the transmission screw 31 to move downwards continuously, the transmission screw 31 pushes the rotating shaft 33 downwards, and the stirring piece 19 can be moved downwards to leave the material washing cavity, as shown in fig. 7. When the stirring piece 19 moves downwards to leave the 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 the washed rice is thrown into the inner pot 3.

After throwing the rice into the inner pot, 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, thereby introducing water in the clean water tank into the washing chamber via the water inlet pipe 99 and flowing into the inner pot via the washing chamber to prepare for cooking.

After the blanking operation is completed, the third driving device 28 may drive the transmission screw 31 to move upward, and after the transmission screw 31 moves upward into the feeding bin 16, the first driving device 21 may drive the feeding bin 16 to return to the storage position. The rotation shaft 33 and the stirring member 19 connected thereto can be returned upward to the original position by the elastic member 40.

According to cooking utensil 1 of this embodiment, interior pot 3, pot cover 4, wash feed bin subassembly 5, clear water tank 81, sewage case 48 all can easily be pulled down and wash, have simplified the cleaning process of whole cooking utensil 1.
