Wherein, the boosting cooking time duration refers to the duration of a single boosting cooking process. The exit condition of the pressure cooking stage is a condition or basis for judging whether to exit/end the pressure cooking stage and enter the pressure relief stage.
Specifically, when the timing duration of the second timer reaches the boosting cooking duration, the representation ends when the boosting cooking process is finished, the controller judges whether a pressure cooking stage exit condition is met or not, if the pressure cooking stage exit condition is met, the pressure cooking stage exits and enters a pressure relief stage, if the pressure cooking stage exit condition is not met, the cooking device is controlled to perform pressure reduction cooking according to the pressure reduction cooking power, the pressure reduction cooking device is controlled to enter the next pressure reduction cooking process, and when the pressure cooking stage exit condition is met, the pressure cooking stage exits and enters the pressure relief stage.

In one embodiment, the controller queries the pre-configured mapping relation table according to the weight of the cooking object, the type of the cooking object and the cooking function during the current cooking to obtain the corresponding pressure-reducing cooking power, pressure-reducing cooking time, pressure-increasing cooking power and pressure-increasing cooking time.

The automatic identification of the weight of the cooking product may include detection by a weight sensor or may be determined from the rate of temperature change and/or the rate of pressure change during the heating or pressure-increasing phase, the rate of temperature/pressure change being inversely related to the weight of the cooking product. Taking the temperature change rate of the heating stage as an example, the slope of the temperature change along with the time in the heating stage is determined as the temperature change rate, specifically, within a fixed heating time length, the more obvious the temperature change/the larger the temperature difference, the faster the temperature change rate is indicated, and within the fixed temperature difference, the shorter the required heating time length is, the faster the temperature change rate is indicated.
In the above embodiment, according to the weight of the cooking object cooked at the current time, the type of the cooking object and the cooking function, the pressure-reducing cooking power in the pressure cooking stage is dynamically determined, the pressure-reducing cooking time, the pressure-increasing cooking power and the pressure-increasing cooking time are dynamically determined, so that the pressure-reducing cooking power, the pressure-reducing cooking time, the pressure-increasing cooking power and the pressure-increasing cooking time are determined in the pressure cooking stage, the pressure-reducing cooking device is controlled to alternately perform pressure-reducing cooking and pressure-increasing cooking, a better cooking effect can be achieved in the same cooking time, or the cooking time is shortened in the same cooking effect.

The preset ratio interval is determined by the reduced pressure cooking power and the increased pressure cooking power in the pressure cooking stage, and may be specifically determined by a power ratio between the increased pressure cooking power and the reduced pressure cooking power, such as [0.8 power ratio, 1.2 power ratio ].
Specifically, the longer the cooking time period of the pressure cooking stage, the larger the first ratio between the pressure-decreasing cooking time period and the pressure-increasing cooking time period, so that the first ratio is positively correlated with the cooking time period of the pressure cooking stage. A first ratio between the reduced-pressure cooking duration and the increased-pressure cooking duration varies with the cooking duration of the pressure cooking stage, and the dynamically varying first ratio is always within a preset ratio interval determined by the reduced-pressure cooking power and the increased-pressure cooking power.
In one embodiment, the initial values of the down cooking time period and the up cooking time period are determined by the weight of the cooking object, the type of cooking object and the cooking function of the current cooking, whereby it can be seen that the first ratio between the down cooking time period and the up cooking time period is determined by the weight of the cooking object, the type of cooking object and the cooking function.

In one embodiment, a second ratio between the reduced pressure cooking period and the increased pressure cooking period is within a preset ratio interval, the second ratio being inversely related to the cooking period of the pressure cooking stage; the preset ratio interval is determined by the pressure reduction cooking power and the pressure boosting cooking power.
Specifically, the longer the cooking time period of the pressure cooking stage, the smaller the second ratio between the pressure-reducing cooking time period and the pressure-increasing cooking time period, so that the second ratio is inversely correlated with the cooking time period of the pressure cooking stage. A second ratio between the reduced pressure cooking time and the increased pressure cooking time varies with the cooking time during the pressure cooking phase, the dynamically varying second ratio being always within a preset ratio interval determined by the reduced pressure cooking power and the increased pressure cooking power.
In the above embodiment, the ratio between the pressure reduction cooking time and the pressure increase cooking time is changed along with the cooking time, and the ratio is smaller and smaller along with the cooking time, so that the pressure inside the electric pressure cooker is higher and higher, and the cooking effect can be improved under the same cooking time.

The preset time period can be customized according to an empirical value, and specifically can be any value in the interval [5, 120min ], such as 30min (minutes), and can also be determined according to the weight of the cooked object cooked at the time.
Specifically, because the pressure reduction cooking frequency in the pressure cooking process is consistent with the pressure increase cooking frequency, in the pressure cooking stage, after the pressure increase cooking process is completed, 1 is added to the pressure reduction cooking frequency to update the pressure reduction cooking frequency, and if the updated pressure reduction cooking frequency reaches the preset frequency, it is determined that the pressure cooking stage exit condition is satisfied.
