[0002] With the development of science and technology, the field of home appliances is ushering in an era of intelligent manufacturing transformation. Intelligence is the development direction of manufacturing automation. Artificial intelligence technology is widely used in almost all links of the manufacturing process. Intelligent manufacturing is to expand, extend and partially replace human mental labor in the manufacturing process through the cooperation between people and intelligent machines. As a kitchen appliance with high steaming efficiency and good quality of steamed rice, the rice steamer has been adopted by managers of most restaurants, schools, and factories, and has become an indispensable main force in kitchen production and processing. Most rice steamers, although they can automatically heat, keep warm, and automatically cut off the power, are semi-automatic rice cooking equipment. Adding rice, adding water, and washing rice need to be done manually, and the lid must be opened and closed manually, and the switch must be started manually to make raw rice into cooked rice. In addition, ordinary rice steamers cannot produce a large amount of cooked rice in a short time. A large amount of rice steamed at the same time is prone to adhesion, undercooked, etc., and the quality is not high. The use of drawer-type trays for batch steaming increases labor and is inefficient.

8. The intelligent rice steamer according to claim 7, characterized in that: The tail end of the rice conveying pipe is provided with a telescopic tube, and a rice entry switch is provided on one side of the multifunctional sealing cover. The telescopic tube is extended to push the rice entry switch to open the rice entry switch, thereby introducing the rice into the inner container.

9. The intelligent rice steamer according to claim 8, characterized in that: The rice entry switch comprises a switch housing, a switch lock tongue, a side inlet arranged at the side of the switch housing, a bottom outlet arranged at the bottom of the switch housing and a lock tongue reset spring; the switch lock tongue is an L-shaped plate structure, the side plate of the switch lock tongue is in contact with the side inlet, and the bottom plate of the switch lock tongue is in contact with the bottom outlet; after the switch lock tongue is translated by the thrust, the side plate leaves the side inlet, and the bottom plate leaves the bottom outlet, so that the side inlet is connected with the bottom outlet; the lock tongue reset spring is arranged on the switch lock tongue, one end of which is connected to the side plate of the switch lock tongue, and the other end is connected to the switch housing part, providing thrust to the switch lock tongue, so that the side plate of the switch lock tongue is in contact with the side inlet, so that the side inlet and the bottom outlet are in a closed state.

10. A rice steaming method for an intelligent rice steaming machine according to any one of claims 1 to 9, characterized in that: The steps include: 1) Add rice according to the set weight into the inner pot; 2) Washing rice: water is introduced into the inner pot through the water spray pipe of the cooking chamber, and the water enters the inner pot through the air permeable port to soak / wash the rice. The inner pot is rotated or swung to wash the rice, and the rice is discharged from the discharge channel on one side of the sedimentation chamber after washing. The inner pot is rotated to correspond to the heat flow input port and the heat flow output port; 3) Cooking rice: water is introduced into the cooking chamber through the water spray pipe, so that the gap between the cooking chamber and the inner pot stores water, and the water level is higher than the rice surface. The steam generating device generates steam heat flow to heat the water and cook the rice; 4) Drainage: Drain the water from the drainage channel on one side of the sedimentation chamber; 5) Steaming rice, a steam generating device generates a steam heat flow to transport steam to the inner pot in the cooking chamber to steam the rice in the inner pot; during the rice steaming process, the inner pot rotates or swings at intervals to make the rice grains loose and discrete; 6) Keep warm: keep warm after steaming the rice.
