The larger the target working time length is, the more difficult the food materials of the type are to be completely cooked, the accurate control of the steam generating device 20 can be realized by controlling the working time length of the steam generating device 20 through the food material type information, and incomplete or excessive heating of food is avoided.

In particular, this embodiment further defines how the controller 50 controls the steam generating device 20 to steam heat the food material. The technical scheme specifically limits three control modes:

the first method determines a target duration of time for which the steam generating device 20 needs to be continuously operated according to the control command, and determines a target temperature of steam which the steam generating device 20 needs to generate within the target duration of time on the basis of the target duration of time.

As shown in fig. 10, the target working time of the vegetable food material is T1, the target temperature is 120 ℃, and the high-temperature rapid treatment can ensure that the vegetables are ripened quickly and do not change color and lose nutrition. The target working time of the meat food material is T2, the target temperature is 100 ℃, and the meat is tender and tender without firewood by slow fire stewing. The target working time of the food materials of grains is T3, the target temperature is 105 ℃, on one hand, the center of the grains can be ensured to be quickly cooked, the cooking time of the grains is prolonged, on the other hand, the surfaces of the grains can be ensured not to be rotten, and the taste is improved.

The second method determines the target duration of the continuous operation of the steam generating device 20 according to the control command, and determines the target quality of the liquid in the steam output by the steam generating device 20 in unit time based on the target duration.

As shown in fig. 11, the target working time of the vegetable food material is T1, and the target mass is 15 g/min, because the water content of the vegetable is high, the drying steam can avoid excessive water content from affecting the taste of the vegetable. The target working time of the meat food material is T2, the target mass is 30 g/min, and the steam with the humidity can not only ensure the meat to be delicious, but also avoid meat flavor loss. The target working time of the cereal food material is T3, the target mass is 40 g/min, sufficient moisture in the steam can ensure the cereal food material to be well cooked, and the taste of the cereal food material is ensured to be proper.

A third time when the target continuous operation of the steam generating device 20 is determined according to the control command, and based on the target temperature of the steam generated by the steam generating device 20 in the target time period and the target quality of the liquid in the steam output by the steam generating device 20 in the unit time are determined.

By limiting the target temperature and the target quality on the basis of limiting the target duration, the controller 50 can more accurately control the operation of the steam generating device 20, and ensure that the steam generated by the steam generating device 20 can meet the cooking requirement of food, thereby improving the reliability of the cooking appliance 1 and improving the quality of the cooked food.
