According to the scheme, the third position is arranged, so that the stroke of the up-and-down movement of the driving shaft 26 can be divided into sections to the material conveying bin 16, the movement stroke of the driving shaft 26 can be reduced, and the driving shaft 26 is prevented from being too long.

When a washing operation is intended, as shown in fig. 5, 13 and 14, 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 screw 31 is sleeved outside the driving shaft 26, so that the driving shaft 26 also moves downwards along with the transmission screw 31 to be engaged with the connecting shaft 27 of the washing assembly 5. The second drive means 24 can now be opened so that the second drive means 24 drives the drive shaft 26 in rotation, so that the drive shaft 26 can drive the connecting shaft 27 in rotation. 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 located above the discharge outlet 9 when the washing operation is performed.

When the washing operation is completed with the intention of draining, the third drive 28 can be opened to drive the drive screw 31 downwards, the drive screw 31 pushing the shaft 33 downwards, so that the stirring element 19 can be moved downwards. When the stirring element 19 is moved downwards to the position where the washing bin cover 17 is moved to the position below the sewage discharge outlet 9, i.e. the communication position, as shown in fig. 6, the third driving device 28 is controlled to stop acting, and at this time, the sewage in the washing chamber can flow to the sewage pipeline 10 and the sewage tank 48 through the sewage discharge outlet 9. It is understood that in other embodiments, the draining operation may be performed while the washing operation is in progress, i.e., the draining operation may be performed while washing, and the feeding operation may be performed while the washing operation is in progress.

When the draining is completed and the rice is to be discharged, the third driving device 28 is controlled to be opened to drive the transmission screw 31 to move downwards, and the transmission screw 31 pushes the rotating shaft 33 downwards, so that the stirring member 19 can move downwards to leave the 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 second driving device 24 is controlled 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 rice-discharging operation is completed, the third driving device 28 can drive the transmission screw 31 to move upwards, and after the transmission screw 31 moves upwards into the feeding bin 16, the first driving device 21 can drive the feeding bin 16 to return to the first 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.

The following describes a method of performing steam control during cooking:

in one embodiment, during cooking, when the steam venting operation is intended for the cooking chamber, the tub cover 17 may be brought into a closed position such that steam in the cooking chamber is vented through the soil outlet 9. The stage may be, for example, a water absorption stage, a temperature rise stage, a boiling stage, a heat retention stage, or the like. The closed position of the wash bin cover 17 may be the position when the cooking appliance is in the initial state as shown in fig. 2.

Preferably, the position of the washing bin cover 17 can be adjusted as needed during cooking so that the portion of the drain outlet 9 communicating with the cooking cavity is variable, i.e., the size of the drain outlet 9 communicating with the cooking cavity can be adjusted. In one embodiment, the position of the wash bin cover 17 may be adjusted such that only a portion of the waste outlet 9 communicates with the cooking cavity. This solution can be implemented, for example, when it is intended to maintain a slight pressure in the cooking chamber, so that the steam in the cooking chamber is not totally expelled, but partially remains in the cooking chamber, thus maintaining a slight pressure in the cooking chamber. In another embodiment, the position of the washing bin cover 17 may be adjusted at a later stage in the cooking process to increase the portion of the drain outlet 9 in communication with the cooking cavity, for example, the portion of the drain outlet 9 in communication with the cooking cavity may be increased at a heat-preserving stage, an exhaust stage, or the like, or the entire drain outlet 9 may be made to communicate with the cooking cavity, thereby accelerating the exhaust speed.

In one embodiment, the wash chamber lid 17 may also be controlled to be in a communicating position during at least one stage of the cooking process such that the cooking chamber is maintained under pressure. For example, the wash silo cover 17 can be brought into a closed position in a pressure maintenance phase after boiling. It will be appreciated that the process is a cooking process other than a washing process.

In one embodiment, a cleaning operation of the sewerage pipeline 10 may also be performed. Before the cooking process begins and/or after the cooking process is finished, the user can manually add fresh water into the cooking cavity or add water through the fresh water tank 81, and control the washing bin cover 17 to be in the sealing position. The heating means are then controlled to heat the fresh water in the cooking chamber so that the generated steam flows via the waste outlet 9 to the waste pipe 10 for cleaning the waste pipe 10.

In one embodiment, it is also possible to allow the steam in the cooking chamber to be discharged through the main body 52 during cooking. For example, when a steam venting operation is intended for the cooking chamber, the wash chamber lid 17 may be controlled to move to an open position, as shown in fig. 7, in which a portion of the steam in the cooking chamber may be vented through the waste outlet 9 and another portion may be vented through the main body 52, particularly through the inlet 7 in the top cover 20.

According to the cooking utensil 1 of the embodiment, the inner pot 3, the pot cover 4, the washing component 5, the clean water tank 81 and the sewage tank 48 can be easily detached for washing, so that the washing process of the whole cooking utensil 1 is simplified.
