In the technical scheme, a specific step of determining a liquid level interval of the food material in the cooking cavity according to the operation current value is further defined, specifically, when the obtained operation current value is smaller than a first parameter threshold value, it is determined that the liquid level of the food material is in a first liquid level interval, and specifically, the first liquid level interval indicates that almost no food material exists in the cooking cavity. When the obtained operation current value is between the first parameter threshold and the second parameter threshold, the liquid level of the food material is judged to be in a second liquid level interval, and specifically, the second liquid level interval indicates that the food material in the cooking cavity is in a low liquid level interval. When the obtained operation current value is between the second parameter threshold and the third parameter threshold, the liquid level height of the food material is judged to be in a third liquid level height interval, and specifically, the third liquid level height interval indicates that the food material in the cooking cavity is a middle liquid level interval. When the obtained running current value is larger than or equal to the third parameter threshold value, the liquid level height of the food material in the cooking cavity is judged to be a fourth liquid level height interval, and specifically, the fourth liquid level height interval is a high liquid level interval. By judging the parameter threshold interval where the operating current value is located, the liquid level interval where the corresponding food material is located can be determined, namely, whether the food material in the cooking cavity is almost free of food material or high, medium and low liquid level intervals is judged, and the process of judging the liquid level of the food material according to the operating current value is realized.

The operation current value of the stirring device is positively correlated with the liquid level of the food in the cooking cavity, namely the operation current value is larger when the liquid level of the food in the cooking cavity is higher, and the operation current value is smaller when the liquid level of the food in the cooking cavity is not higher.

In particular, after the liquid level of the food material in the cooking cavity is determined according to the operating current value, the operation mode of the corresponding domestic electric appliance is determined according to the liquid level height of the food material, namely, after the liquid level height of the food material is determined, the household electrical appliance is controlled to work according to the operation mode corresponding to the liquid level height, the difficult problem of pain point that the high liquid level is easy to overflow and complain in the related technology can be effectively avoided, the problem of dry burning caused by too low liquid level or no liquid in the cooking cavity can be avoided, in other words, the corresponding operation mode is selected for the judged liquid level height of the food material, when effectively reducing life electrical apparatus high liquid level and stirring and spilling over, can improve the holistic stability of life electrical apparatus and reliability, improve life electrical apparatus's life, further promote user experience.

In the above technical solution, the step of controlling the stirring device and the heating device to operate according to the operation mode specifically includes: controlling the stirring device and the heating device to stop running based on the fact that the liquid level of the food material in the cooking cavity is in a first liquid level interval; controlling the heating device to operate according to the first power until the food material is boiled and controlling the stirring device to operate according to the first preset rotating speed based on the fact that the liquid level of the food material in the cooking cavity is in the second liquid level height interval; controlling the heating device to operate according to the first power until the food material is boiled and controlling the stirring device to operate according to the second preset rotating speed based on the fact that the liquid level of the food material in the cooking cavity is in a third liquid level interval; based on the fact that the liquid level of the food material in the cooking cavity is located in a fourth liquid level interval, the heating device is controlled to operate according to the first power until the food material is boiled, and the stirring device is controlled to operate according to a third preset rotating speed, wherein the second preset rotating speed is higher than the third preset rotating speed and lower than the first preset rotating speed.

In the technical scheme, the specific steps of selecting the corresponding operation mode according to the liquid level of the food material are limited, specifically, when the liquid level of the food material is within a first liquid level interval, namely, almost no food material exists in the cooking cavity, the stirring device and the heating device are controlled to stop working at the moment, wherein it needs to be explained that the heating device does not heat during a period of time when a motor of the stirring device stirs at a constant preset rotating speed, namely, when almost no food material exists in the cooking cavity, the stirring device and the heating device are controlled not to work, so that the dry burning caused by controlling the heating device to work due to the fact that no food material exists in the cooking cavity can be avoided, the operation stability and the service life of the household electrical appliance are improved, in addition, the situation of wasting electric energy caused by controlling the stirring device to work due to almost no food material exists in the cooking cavity can also be prevented, the energy is saved.
