An embodiment of the present invention provides another method for controlling a cooking appliance, which is implemented on the basis of the above embodiment, and the method for controlling the cooking appliance can be executed by the above cooking appliance, referring to a flowchart of another method for controlling a cooking appliance shown in fig. 4, the method for controlling a cooking appliance in this embodiment includes the following steps:

in step S402, a cooking mode of the cooking appliance is determined.

The cooking mode of the cooking appliance in the embodiment can be selected by a user through the display screen or the APP, and the controller receives the cooking mode selected by the user.

Step S404, receiving the identification signal sent by the radio frequency identification label.

The controller may start receiving the identification signal after the door body is closed, for example: receiving a door control signal sent by a door control switch of the cooking appliance; and if the gating signal represents that the door body of the cooking appliance is closed, receiving the identification signal sent by the radio frequency identification tag.

When the cooking appliance is started and starts to work, the door control switch of the cooking appliance can detect that the door body is closed. The radio frequency identification unit can detect whether the radio frequency identification label of the cooking accessory sends an identification signal or not, and the radio frequency identification unit transmits the identification signal to the controller.

In step S406, a cooking operation is controlled based on the recognition signal and the cooking mode.

If the identification signal is identified in the cooking cavity, the controller judges that food is in the cavity, and the radio frequency identification unit establishes communication with the RFID tag of the cooking appliance; if the fact that no identification signal exists in the cooking cavity is identified, the controller judges that no food exists in the cavity. The controller may determine whether the cooking mode selected by the user has been received before the identification signal is received. Specifically, the following 4 cases are possible:

(1) If the identification signal transmitted from the rfid tag is not received and the cooking mode of the cooking appliance is not determined, the cooking operation is not performed.

If the controller judges that no food exists in the cavity and does not receive the cooking mode selected by the user, the controller does not process the food and does not execute any cooking operation.

(2) And if the identification signal transmitted by the radio frequency identification tag is not received and the cooking mode of the cooking appliance is determined, controlling the cooking operation.

If the controller determines that there is no food in the cavity and previously receives the cooking mode selected by the user, the controller may correspond to the cooking mode according to the control cooking operation, for example: and if the identification signal transmitted by the radio frequency identification tag is not received and the cooking mode of the cooking appliance is determined, controlling the cooking operation to correspond to the cooking mode.

Wherein, if the cooking mode comprises a preheating stage, the cooking operation comprises preheating, and preheating in the cooking operation is executed; if the cooking mode does not include the preheating stage, the cooking operation does not include preheating, and the cooking operation is not performed.

In the embodiment, the cooking utensil is preheated with the maximum power load during preheating, so that the cooking utensil can be ensured to finish preheating in the shortest time, for example: the preheating in the cooking operation is performed based on the maximum power load.

In summary, in the embodiment, the cavity judgment can be performed according to the RFID tag, different preheating modes are provided, heating is performed in the mode of the maximum load in the cavity state, preheating is completed at the fastest speed, and the cooking time of a user is saved.

(3) And if the identification signal sent by the radio frequency identification tag is received and the cooking mode of the cooking appliance is not determined, controlling the cooking operation to correspond to the identification signal and executing the cooking operation.

Specifically, if an identification signal sent by the radio frequency identification tag is received and the cooking mode of the cooking appliance is not determined, determining at least one cooking mode corresponding to the identification signal based on a preset corresponding relation; determining a target cooking mode from at least one cooking mode; the control cooking operation corresponds to the target cooking mode.

Wherein, can prerecord the corresponding relation between different kinds of culinary art annex radio frequency identification label and the culinary art mode, with the corresponding relation storage to cooking utensil's controller in. If the controller determines that food is in the cavity and does not receive the cooking mode selected by the user before, the controller may determine at least one cooking mode corresponding to the identification signal based on a preset corresponding relationship, so that the user can conveniently select a target cooking mode directly from the determined at least one cooking mode to control the cooking operation to correspond to the target cooking mode.

(4) And if the identification signal transmitted by the radio frequency identification tag is received and the cooking mode of the cooking appliance is determined, controlling the cooking operation.

If the controller determines that there is food in the cavity and previously receives the cooking mode selected by the user, the controller may determine whether the machine has been preheated previously, for example: if the identification signal sent by the radio frequency identification tag is received and the cooking mode of the cooking appliance is determined, determining whether the cooking appliance has performed preheating; if yes, continuing to execute the cooking operation; if not, the preheating operation is started.

Wherein, the continuing of the preheating operation includes two cases. Performing a cooking operation after the preheating if the cooking operation includes the preheating; if the cooking operation does not include preheating, the cooking operation is started.

Specifically, the present embodiment may determine whether the cooking appliance has performed the preheating operation by: determining whether the recognition signal is matched with the cooking mode based on the corresponding relation; if yes, controlling the cooking operation to correspond to the cooking mode; if not, executing a first reminding operation; and responding to the confirmation operation aiming at the first reminding operation, and executing the cooking operation corresponding to the confirmation operation.

For example, if the controller determines that there is food in the cavity and receives the cooking mode selected by the user before, the controller determines whether the cooking accessory matches the cooking mode, and if so, controls the cooking operation corresponding to the cooking mode, for example: judging whether the machine is preheated or not in the prior art, and if the machine is preheated, directly executing cooking operation; if the preheating is not carried out, preheating is carried out firstly.

And if not, reminding the user whether to replace the cooking accessory, the cooking mode or not and whether to continue cooking (namely the first reminding operation).

If the user selects to continue cooking (confirmation operation of the first reminding operation), judging whether the previous machine is preheated or not, and if the previous machine is preheated, directly executing the cooking operation corresponding to the confirmation operation; if the preheating is not carried out, the preheating operation is carried out firstly, and then the cooking operation is carried out.

If the user selects to replace the cooking accessory or the cooking mode, the user can return to the previous layer for identification and judgment.

In conclusion, in the embodiment, cavity detection can be performed according to the identification signal, and the cooking mode required by the user is directly jumped to on the basis of quickly identifying the cooking mode, so that the operation of the user can be simplified, the preheating time is saved, the user requirement is met, and the user experience is improved.

Step S408, after the cooking operation is finished, the identification signal sent by the radio frequency identification label is received.

The embodiment also provides a prompting method for taking and placing food after the cooking operation is finished, and after the food in the intelligent cooking appliance is cooked, the cooking accessory identification signal in the cooking cavity can be detected through the radio frequency identification technology so as to judge whether the food is taken out.

Step S410, if the target time for successfully receiving the identification signal is greater than a preset first time threshold, detecting a cavity temperature of the cooking appliance.

If the radio frequency identification unit judges that the identification signal of the cooking accessory exists in the cavity and is not interrupted (namely the target time is greater than the first time threshold), judging that the food is not taken out; if the radio frequency identification unit judges that the identification signal of the cooking accessory does not exist in the cavity, the food is judged to be taken out.

When detecting that the cooking accessory is not taken out after the intelligent cooking appliance finishes cooking, a second reminding operation can be executed to prompt the user to take out food. Meanwhile, temperature monitoring can be started to detect the cavity temperature of the cooking utensil.

Step S412, if the cavity temperature is lower than the preset temperature threshold and the target time is less than the preset second time threshold, performing heat preservation operation.

When the temperature in the cavity is lower than the safe temperature and does not exceed the built-in maximum duration (namely the second time threshold) of the cooking utensil, the cooking utensil automatically runs the heat preservation function to preserve heat. Meanwhile, a third reminding operation can be executed based on a preset reminding interval, for example: reminding for many times at intervals of 5-10 min.

In conclusion, whether the user takes out food after cooking is finished can be detected through the identification signal in the embodiment, and the temperature is automatically kept when the temperature in the cavity is lower than the set safe temperature in the state that the food is not taken out, so that the phenomenon that the food is cooled when the user forgets to remember the food is avoided, and the satisfaction degree of the user is increased.

Further, if the target time is greater than or equal to the second time threshold, a shutdown operation is performed. When the cooking appliance judges that the food in the cavity is not taken out and exceeds the built-in maximum duration (namely the second time threshold) of the cooking appliance, the intelligent cooking appliance can be automatically powered off and shut down and does not remind any more.

And the second time threshold value can be 1-2 hours, the cooking utensil is not kept warm after the second time threshold value is exceeded, and the automatic power-off shutdown is not reminded.

It should be noted that the food taking and placing prompting method provided in steps S408-S412 only detects after the cooking procedure is finished, and does not operate the procedure in other time periods, that is, the user can store the cooking accessory in the cooking cavity in the power-off state.

The manner of executing the reminding operation may include at least one of the following: buzzer alarm, text prompt, voice prompt or message sending to the mobile phone terminal, vibration prompt of the smart phone, etc.

According to the method provided by the embodiment of the invention, the intelligent cooking appliance and the accessories with the RFID detection function are provided, the cooking mode required to be called by the user is detected through the RFID tags on different cooking accessories, and the cooking mode required by the user is directly jumped to, so that the user can conveniently control the cooking appliance and the accessories.
