The amount of rice flowing into the wash chamber can be calculated by time.

After the blanking operation is completed or at the same time of the blanking operation, the control unit can control the water pump of the water inlet assembly to be started, so that water in the clean water tank is introduced into the washing bin main body through the water inlet pipe to be ready for the washing operation.

In a preferred embodiment, the control unit controls the feeding mechanism to return to the third position when the discharging operation and the draining operation are completed. 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 drive assembly and the washing bin assembly are in a ready-to-mate state, in which the position of the drive device is determined and the drive shaft is in a state to be mated (moved). In the third position, the feed bin 16 is not in communication with the outlet 14 of the storage bin 13 and the feed opening 7 of the wash 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. In other embodiments, the drive assembly and the sink assembly may also be in a mated condition when the feed mechanism is in the third position.

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 material washing operation is finished and the water is discharged, the control unit controls the material washing bin cover to move to the communicating position, so that the sewage outlet is communicated with the material washing cavity. 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 water discharge is completed and the blanking operation is intended, the control unit controls the washing bin cover 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.

At the same time of the blanking operation or after the blanking operation, the control unit controls the feeding mechanism to move to the matching position, and the control unit controls the water pump of the water inlet assembly to be started, so that water in the clean water tank is introduced into the inner pot through the water inlet pipe and the material washing cavity to be ready for cooking.

After the blanking operation and the draining operation are 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 feeding bin 16, the first driving device 21 may drive the feeding 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. The cooking appliance may then perform a cooking step.

In another embodiment, the control unit may control the cooking appliance to perform the above steps, i.e., the steps of discharging, draining, washing, draining, blanking, etc., in a cycle, with the specific number of cycles being determined by the amount of rice selected by the user. For example, when a cup of rice is selected, the above steps are cycled once; when two cups of rice are selected, the steps are circulated twice; when selecting N cups of rice, the above steps are cycled N times. The cooking step is entered after N steps.

The method of steam control during cooking is described below:

in one embodiment, the washing compartment cover 17 may be brought into a closed position when it is intended to perform a steam-discharging operation on the cooking cavity during cooking, so that steam in the cooking cavity is discharged through the drain 9. The stage may be, for example, a water absorption stage, a temperature rising stage, a boiling stage, a heat retaining stage, etc. The closed position of the washing tub cover 17 may be a position when the cooking appliance is in an initial state as shown in fig. 2.

Preferably, the position of the washing bin cover 17 can be adjusted as required during cooking so that the portion of the drain 9 communicating with the cooking cavity is variable, i.e. the size of the drain 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 drain 9 communicates with the cooking cavity. This solution can be implemented, for example, when it is intended to keep the cooking cavity at a micro-pressure, so that the rate of discharge of the steam in the cooking cavity can be slowed down, thus keeping the cooking cavity at a micro-pressure. In another embodiment, the position of the cover 17 of the washing bin may be adjusted at a later stage in the cooking process to increase a portion of the drain 9 communicating with the cooking cavity, for example, a portion of the drain 9 communicating with the cooking cavity may be increased in a heat-insulating stage, an air-discharging stage, or the like, or the entire drain 9 may be made to communicate with the cooking cavity, thereby increasing an air-discharging speed.

In one embodiment, the wash bin cover 17 may also be controlled to be in a communication position during at least one stage of the cooking process such that the cooking cavity is maintained in a pressurized state. For example, the flushing bin cover 17 may be brought into a communication position during a pressure maintenance phase after boiling.

In another embodiment, the washing compartment cover 17 may be brought to an open position when the steam-discharging operation of the cooking compartment is intended during cooking, so that steam in the cooking compartment is discharged through the discharge opening and the washing compartment. The stage may be, for example, a water absorption stage, a temperature rising stage, a boiling stage, a heat retaining stage, etc.

Preferably, the opening degree of the washing tub cover 17 may be adjusted as needed during cooking such that the portion of the discharge opening communicating with the cooking cavity is variable, i.e., the size of the discharge opening communicating with the cooking cavity may be adjusted. In one embodiment, the degree of opening of the washing silo cover 17 may be adjusted such that only a portion of the discharge opening communicates with the cooking chamber. This solution can be implemented, for example, when it is intended to keep the cooking cavity at a micro-pressure, so that the rate of discharge of the steam in the cooking cavity can be slowed down, thus keeping the cooking cavity at a micro-pressure. In another embodiment, the opening degree of the cover 17 of the washing bin may be adjusted at a later stage in the cooking process to increase a portion of the discharge port communicating with the cooking cavity, for example, a portion of the discharge port communicating with the cooking cavity may be increased at a temperature maintaining stage, a gas exhausting stage, or the like, or the entire discharge port may be made to communicate with the cooking cavity, thereby increasing the gas exhausting speed.

The cooking appliance according to the present invention may also perform a self-cleaning operation. In one embodiment, a decontamination operation of the trapway 10 may be performed. Before the start of the cooking process and/or after the end of the cooking process, the user can manually add fresh water to the cooking cavity or perform a water adding operation through the fresh water tank 81 and control the washing bin cover 17 to be in a closed position. The heating means is then controlled to heat the clear water in the cooking cavity such that the steam generated in the cooking cavity flows to the drain pipe 10 via the drain port 9 to purify the drain pipe 10.

In one embodiment, a purge operation of the wash chamber may be performed. Before the start of the cooking process and/or after the end of the cooking process, the user may manually add fresh water to the cooking cavity or perform a water adding operation through the water inlet assembly and control the movement of the washing tub cover 17 to the open position. The heating device is then controlled to heat the clean water in the cooking cavity so that steam generated in the cooking cavity passes through the washing bin body to clean the washing cavity.

In another embodiment, the user can manually add clear water into the material washing cavity or control the water inlet component to add water into the material washing cavity before the cooking process starts, at least one stage in the cooking process or after the cooking is finished, so as to wash the material washing bin main body.

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.
