In step S101, the pressure cooking appliance determines cooking parameters based on the acquired cooking instructions, and starts cooking based on the cooking parameters.

In the embodiment of the present application, the cooking instruction is usually triggered by the user. Before the pressure cooking appliance cooks, the user will select the corresponding program according to the cooking ingredients. When the user selects the cooking program, the cooking instruction is initiated. The pressure cooking appliance determines cooking parameters based on the acquired cooking instructions, and starts cooking based on the cooking parameters. When implemented, the pressure cooking appliance determines the cooking program selected by the user after receiving the cooking start instruction, thereby determining the cooking program Each cooking parameter in the corresponding cooking process, and then the pressure cooking appliance performs cooking based on each cooking parameter.

Exemplarily, the cooking parameters of the pressure reduction phase and the pressure holding phase can be determined according to the cooking pressure and cooking time set by the user. The temperature range of the pressure stage and the temperature range of the pressure reduction stage can be the same or different; the pressure retention time of the pressure retention stage and the pressure reduction time of the pressure reduction stage are determined according to the cooking time set by the user. In some embodiments, the user can also set the exhaust cycle of the depressurization phase.

Exemplarily, the cooking time set by the user is 30 minutes, the depressurization time can be determined to be 10 minutes, the cooking pressure set by the user is 100 kilopascals (kpa, kilopascal), and the temperature range of the depressurization stage can be determined to be 120 degrees Celsius (°C). ) To 121°C.

In the embodiment of the present application, the oil draining device and the pressure cooking appliance are detachable. After cooking, the user can pour out the grease in the oil draining device and clean the oil draining device. In actual implementation, the user can predict the fat content of the cooked food based on the cooked food, and determine whether to activate the oil drain function. Correspondingly, the cooking instruction instructs to drain the oil during the cooking process.

In step S102, when the pressure cooking appliance determines to enter the pressure reduction phase, it controls itself to exhaust in a preset period.

In the embodiment of the present application, the pressure-reducing stage is the pressure-holding stage before the pressure-holding stage is reached, and the pressure cooking appliance controls itself to enter the pressure-reducing stage. The cooking parameters in the embodiments of the present application also include the pressure-holding duration of the pressure-holding phase. After entering the pressure-holding phase, the pressure cooking appliance determines to enter the pressure-reducing phase.

In the embodiment of the present application, the preset period may be set by the user before starting the cooking instruction, or may be automatically determined by the pressure cooking appliance according to a program.

In step S103, the pressure cooking appliance obtains the first temperature in the pot.

In the embodiment of the present application, the real-time acquisition of the first temperature in the pot of the pressure cooking appliance can be achieved by obtaining the first temperature in real time through a temperature sensor provided in the pot of the pressure cooking appliance. The temperature sensor is usually set in pressure cooking. On the inner wall of the lid of the appliance.

In step S104, the pressure cooking appliance controls its own working state according to the first temperature and the first temperature range, so that cooking ingredients boil indirectly, and the fat in the cooking ingredients enters the oil draining device.

In the embodiment of the present application, by controlling the working state of the pressure cooking appliance, the cooking food is made to boil intermittently, so that the fat in the cooking food enters the oil draining device until the pressure reduction time is reached. It should be noted that, in the embodiment of the present application, there is no strict sequence of step S102, step S103, and step S104.

In the embodiment of the present application, the pressure cooking appliance controls its own working state by comparing the first temperature with the first upper temperature threshold and the first lower temperature threshold of the first temperature interval. Exemplarily, when the first temperature is greater than the first upper limit temperature threshold, the heating device in the pressure cooking appliance is stopped; when the first temperature is less than the first lower limit temperature threshold, the heating device in the pressure cooking appliance operates to Heat it up. In the embodiment of the present application, the heating device in the pressure cooking appliance is controlled to repeatedly heat by the first temperature and the first temperature interval, so that the temperature in the pot of the pressure cooking appliance is maintained within the range of the first temperature interval. The pressure in the pressure cooking appliance decreases, and the boiling point of the cooking ingredients in the pot decreases, so that the cooking ingredients boil. When there is no exhaust, the pressure in the pressure cooking appliance rises and the boiling point rises, so that the cooking ingredients stop boiling. Achieve intermittent boiling of cooking ingredients. In the embodiments of the present application, when the cooking food is boiling, at least part of the fat in the cooking food enters the oil draining device, thereby achieving the effect of separating at least part of the fat from the cooking food. In the embodiment of the present application, the oil draining device is arranged inside the pot and above the cooking ingredients, and the oil draining device may be an oil draining kettle.

The cooking control method provided by the embodiment of the present application determines the depressurization duration and the first temperature interval during depressurization based on the cooking instruction, after entering the depressurization phase, the pressure cooking appliance is controlled to exhaust, and the pressure cooking appliance is obtained in real time The first temperature inside and the determined first temperature range control the working state of the pressure cooking appliance, so that the cooking ingredients boil intermittently. When boiling, the grease enters the oil draining device, thereby realizing at least part of the grease in the cooking ingredients to be separated It reduces the oil in the food, thereby avoiding the appetite and health of the user from being affected by excessive oil.

In some embodiments, the first temperature interval includes a first upper temperature threshold and a first lower temperature threshold. Correspondingly, step S104 "controls its own work according to the first temperature and the first temperature interval). "Status" can be achieved through the following steps:

Step S1041: When the pressure cooking appliance determines that the first temperature is greater than the first upper temperature threshold, it controls its own heating device to stop working.

In the embodiment of the present application, after the pressure cooking appliance obtains the first temperature in the pot through the temperature sensor, the first temperature can be compared with the first upper temperature threshold and the first lower temperature threshold of the first temperature interval to determine The magnitude relationship between the first temperature and the first upper temperature threshold and the first lower temperature threshold in the first temperature interval. Exemplarily, the first temperature range is: 120°C to 121°C, the first upper temperature threshold is 121°C, and the first lower temperature threshold is 120°C. When the first temperature is greater than 121°C, the pressure cooking appliance controls its own heating The device stops heating, which reduces the temperature in the pot.

In step S1042, when the pressure cooking appliance determines that the first temperature is less than the first lower temperature threshold, it controls the heating device to operate at the first power.

Continuing the above example, when the first temperature is less than 120°C, the heating device is controlled to work at the first power to perform heating so that the temperature is greater than or equal to 120°C.

In the embodiment of the present application, the heating device is controlled to operate or stop working according to the first temperature and the first temperature range, so that the temperature of the cooking ingredients in the pressure cooking appliance is maintained in the first temperature range, and when the heating device is exhausted , The pressure in the pressure cooking appliance decreases, and the boiling point of the cooking ingredients becomes lower, which makes the cooking ingredients boil. When it is not exhausted, the pressure in the pressure cooking appliance increases, making the boiling point of the cooking ingredients increase, making the cooking ingredients Stop boiling, so that cooking ingredients boil intermittently.

In some embodiments, step S1042 "the pressure cooking appliance controls the heating device to work at the first power" can be implemented through steps S42A to S42C in FIG. 2:

In the embodiment of the present application, when the cooking amount is determined, the pre-stored cooking amount power relationship table can be queried to determine the first power adjustment supply ratio corresponding to the cooking amount, for example, the first power adjustment ratio is P:Q , The P and Q are both integers.

Regardless of the influence of other external factors on pressure cooking appliances, the more cooking capacity, the greater the heating power required, and the less cooking capacity, the lower the heating power required. Therefore, the relationship between the cooking capacity and the power is established in advance, and the Store in the storage area of the pressure cooking appliance. After obtaining the cooking amount, by querying the cooking amount power relationship table, it is determined that the power adjustment ratio of the first power corresponding to the current cooking amount is P:Q.

In the embodiment of the present application, when the heating device is used for heating, the cooking amount of the cooked food is obtained to determine the power regulation ratio of the first power. The greater the cooking amount, the greater the power regulation ratio of the first power, thereby accelerating the cooking speed. , When the cooking volume is small, the power adjustment ratio of the first power is small, so as to prevent the temperature from rising too fast and facilitate temperature control.
