Description

Cooking appliance, control method thereof, electronic device and storage medium Technical Field The present invention relates to the technical field of household appliances, and in particular, to a cooking appliance, a control method for a plurality of lifting structures in the cooking appliance, a cooking control method for the cooking appliance, an electronic device, and a storage medium. Background In the field of household appliances, the electric rice cooker and other cooking appliances are widely applied and become one of the necessary kitchen appliances in the family. Along with the improvement of living standard, the requirements of people on the heating mode and precision in the cooking process are higher and higher, so that the requirements on cooking appliances are also higher and higher. In the heating process of the cooking utensil, particularly in special environments such as a plateau, the phenomenon of pot overflow is very easy to occur. To prevent the occurrence of the overflow phenomenon, the heating power may be reduced by the program control in the cooking appliance, but this may affect the cooking effect. In the prior art, the purpose of overflow prevention can be realized through an air pump. Cold air is blown into the inner pot through the air pump to break bubbles, so that the overflow-preventing function of the electric cooker is realized. However, the cooking appliance with the air pump is easy to generate loud noise when the air pump works, and thus the rest of a user can be seriously disturbed. The solution of partially reducing the noise of the air pump has the effect of reducing the anti-overflow efficiency. Disclosure of Invention In order to at least partially solve the problems in the prior art, a heating control method and system of a cooking appliance, and a storage medium are provided. According to one aspect of the invention, a cooking appliance is provided, comprising a pot body comprising an inner pot and a plurality of lifting mechanisms, wherein the inner pot is supported on the lifting mechanisms, and the lifting mechanisms are used for forming a height combination which changes back and forth for a plurality of times in the execution process of a target cooking function so as to enable the inner pot to shake in the execution process of the target cooking function, and the lifting mechanisms respectively have corresponding lifting heights in each formed height combination. According to the cooking utensil provided by the embodiment of the invention, the height combination of front and back changes can be formed by the plurality of lifting mechanisms in the execution process of the target cooking function, so that the inner pot shakes in the execution process of the target cooking function, and the occurrence of the bumping phenomenon can be prevented. The scheme does not need to arrange an air pump, so that the noise of the cooking utensil can be reduced to a certain extent while the anti-overflow effect is ensured, and the cooking efficiency is not influenced. The anti-overflow scheme can effectively improve user experience. Illustratively, the pot further comprises a heating device disposed between the inner pot and the plurality of lifting structures, the inner pot being supported on the plurality of lifting structures by the heating device. Therefore, the inner pot is supported on the lifting mechanisms through the heating device, so that the inner pot is prevented from overflowing when shaking is realized, and the heating effect of the inner pot is not influenced. Illustratively, any of the plurality of lifting mechanisms includes a motor having a cam disposed on an output shaft thereof and a drive rod disposed on the cam. Therefore, the cam is simple to realize and low in cost. Illustratively, the cooker body further comprises a heating device arranged between the inner pot and the plurality of lifting structures, the inner pot is supported on the plurality of lifting structures through the heating device, wherein the transmission rod is fixed on the heating device, a concave part is arranged at one end of the transmission rod, which is contacted with the cam, and the concave part can be embedded with the convex part on the cam. Therefore, the concave part arranged at one end of the transmission rod, which is in contact with the cam, can enable the transmission rod and the cam to be tightly attached, and prevent the transmission rod from falling off in the rotation process of the motor. The cooking appliance further comprises a cover body, wherein the cover body is arranged on the cooker body in an openable mode, a cooking space is formed when the cover body is buckled to the cooker body, the cover body comprises a detachable cover and an upper cover, the detachable cover and the upper cover are connected through a spherical connecting piece, and/or at least one elastic piece is arranged between the detachable cover and the upper cover. Therefore, based on the
