The pot lid is also in a closed state, and at this time, the storage space is closed. In some embodiments, the pot lid and pot body are removably connected, such that a user can separate the pot lid and pot body to expose storage space. In some other embodiments, the pot lid and the pot body can be hingedly connected, such that a user can rotate the pot lid to expose storage space.

The pot lid has an overflow prevention plate, and the overflow prevention plate is provided with a steam through hole, so that during cooking, steam in the storage space can reach the pan lid through the steam through hole, and can be further discharged from the pan lid.

FIG. 10 is a flowchart of a method for controlling heating of a cooking utensil, and the method of controlling heating of a cooking utensil according to an embodiment of the second aspect of the present invention may include the following steps.

S1: When the cooking appliance turns on the cooking function, the first heating device controls the heating to be turned on, and the temperature measuring section acquires the steam temperature within the pot body.

In one embodiment of the invention, the cooking appliance comprises a controller, and when the cooking appliance turns on the cooking function, the controller controls the first heating device to turn on the heating, and the temperature measuring part is in the body of the cooking pot. transmitting the steam temperature value to the controller after obtaining the steam temperature, the controller can control the first heating device according to the steam temperature value, and the controller corresponds the heating power of the first heating device according to the steam temperature value. can be adjusted accordingly. At this step, the temperature measurement section can only obtain the steam temperature within the pot body.

S2, when the steam temperature in the pot body reaches the first preset temperature, the second heating device is controlled to turn on the heating, and the temperature measurement part obtains the temperature of the overflow prevention plate; The second heating device is controlled according to the temperature of the overflow prevention plate. In this staircase, the temperature measurement section can only obtain the temperature of the overflow prevention plate.

That is, the cooking process is divided into two steps, in the first step, the first heating device turns on the heating, and the temperature measuring part acquires the steam temperature inside the pot body. In the second step, the second heating device turns on the heating and the temperature measurement unit acquires the temperature of the overflow prevention plate. A second heating device in the pot lid heats the pot body and controls the second heating device according to the temperature of the overflow prevention plate.

In some embodiments of the present invention, the cooking information includes a cooking type, and the cooking type may be rice, porridge, soup, short ribs, chicken, beans, etc. The step of controlling the second heating device according to the temperature of the overflow prevention plate includes steps S21 and S22.
In S21, a target temperature of the pot lid is determined according to the type of cooking. Different cooking types have different pot lid target temperatures, and after the user selects a cooking type, the controller adjusts the corresponding pot lid target temperature.
In S22, identify the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid, adjust the heating power of the second heating device according to the temperature difference, and adjust the temperature of the overflow prevention plate to the target temperature of the pot lid. adapt to.

Specifically, when the temperature of the overflow prevention plate is lower than the target temperature of the pot lid and the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is large, the controller reduces the heating power of the second heating device. can be increased, thereby accelerating the reduction in temperature difference. When the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is small, the controller can appropriately reduce the heating power of the second heating device, so that the temperature of the overflow prevention plate reaches the target temperature of the pot lid. While avoiding overheating, the power consumption of the cookware can also be reduced.

At the same time, the cooking type is determined by the program, and if the cooking type is a rice cooking type function, the temperature of the overflow prevention plate is controlled to be maintained at T12, and if the cooking type is a porridge or soup type function, overflow prevention is performed. The temperature of the plate is controlled to be maintained at T13, and when the cooking type is other function, the temperature of the overflow prevention plate is controlled to be maintained at T14 until the cooking process is completed.
