In the embodiment of the invention, three weighing points are set for a weighing point set at the bottom of the tray, and the weighing point set comprises: the first weighing point corresponds to first weighing data, the second weighing point corresponds to second weighing data, and the third weighing point corresponds to third weighing data.

S52, when the sum of the first weighing data, the second weighing data and the third weighing data is larger than a second threshold value, determining that the pot body is placed on the tray.

A second threshold value is preset, which is smaller than the weight of the pan body (it can also be understood that the second threshold value is much smaller than the weight of the pan body), and the purpose of the second threshold value is to detect whether there is a pan body placed on the tray under no special condition (for example, other objects than the pan body are placed on the tray).

In an example, the weight of the pan body is 0.6kg, and the second threshold may be set to 0.1kg, for example.

And S53, when the sum of the first weighing data, the second weighing data and the third weighing data is smaller than or equal to a second threshold value, determining that the pan body is not placed on the tray, and displaying a reminding message that the pan body is not placed on the tray.

In the embodiment of the invention, in order to ensure the accuracy of detecting the placement state of the pot body, when the pot body is placed on the tray, the placement state of the pot body is required to be judged again according to the weighing data corresponding to the key set (whether the pressure born by the three key sets is balanced or not), and the placement state of the pot body is determined, so that the damage of cooking equipment (for example, the damage of the cover caused when the cover is closed when the correct cooking pot is not placed on the pot body) can be effectively avoided.

Further, the difference value is used for representing the difference between the first weighing data, the second weighing data and the third weighing data, and the smaller the difference value is, the more balanced the stress among the first weighing point, the second weighing point and the third weighing point is represented.

The preset formula may be a calculation formula of standard deviation, for example:

In an alternative scheme of the embodiment of the present invention, the preset formula may also use variance instead of standard deviation, and accordingly, only the magnitude of the first threshold needs to be adjusted.

And S55, when the difference value is smaller than or equal to a first threshold value, determining that the placement state of the pot body on the tray is correct.

When the difference value corresponding to the first weighing data, the second weighing data and the third weighing data is smaller than a first threshold value, the balance of the pressures of the first weighing key point, the second weighing key point and the third weighing key point is determined, and then the placement state of the pot body on the tray is determined to be correct.

And S57, when the difference value is larger than a first threshold value, determining that the placement state of the pot body on the tray is wrong, and displaying a reminding message of the wrong placement state of the pot body on the tray.

In the embodiment of the invention, when the difference values corresponding to the first weighing data, the second weighing data and the third weighing data are smaller than the first threshold value, the imbalance of the pressures exerted by the first weighing key, the second weighing key and the third weighing key (for example, the situation that the pan body is not flat and is inclined) is determined, and then the placement state of the pan body on the tray is determined to be wrong, and a reminding message for showing the wrong placement state of the pan body on the tray is displayed, for example, a status error is displayed on a display panel of the cooking equipment, and the pan body is replaced.

In an alternative scheme of the embodiment of the invention, when the placement state of the pan body on the tray is determined to be wrong, besides the reminding message for showing the wrong placement state of the pan body on the tray, a warning mode can be adopted for prompting, such as voice broadcasting, buzzer warning and the like.

And S58, after the food material placement is determined to be completed, acquiring first weighing data, second weighing data and third weighing data corresponding to the first weighing key point, the second weighing key point and the third weighing point.

In this embodiment, it is determined that the placement state of the pan body on the tray is correct, and in the process that the user places the food material in the pan body according to the reminding message, whether the placement of the food material is completed is judged by weighing data corresponding to the weighing point set, and the judging step may be: detecting whether the first weighing data corresponding to the first weighing point, the second weighing data corresponding to the second weighing point and the third weighing data corresponding to the third weighing point are changed or not, and if the weighing data corresponding to the three weighing points are not changed within the preset time (for example, 3 s), determining that the food placement is completed.

In an alternative scheme of the embodiment of the invention, a food material placement completion button can be further arranged on the display panel of the cooking device, and after the user finishes adding the food material in the pot body, the food material placement completion button is triggered, so that the step of weighing the food material is performed.
