Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a method for controlling a rice cooking process according to an embodiment of the present invention, which may be used in various cooking appliances, such as an electric rice cooker, as shown in fig. 1, and which may include the following steps.
In step S110, the cooking container temperature is detected by the temperature detector in the boiling stage.
For example, when a rice cooker is used for cooking rice, a temperature sensor may be used to detect the temperature of the bottom of the cooker.
In an embodiment, detecting the cooking vessel temperature by the temperature detector during the boiling phase may include periodically detecting the cooking vessel temperature by the temperature detector during the boiling phase.
For example, when a rice cooker is used for cooking rice, the temperature of the bottom of the cooker is detected once every preset duration.
In step S120, it is determined whether the temperature in the cooking container enters a steady state according to the detected cooking container temperature.
Wherein when the speed of the temperature change of the cooking container is less than the limit speed, the state of the temperature in the cooking container is defined as a steady state.
For example, after the rice cooking process enters the boiling stage from the temperature rising stage, the temperature of the inner pot of the electric rice cooker still rises at a fast speed until the rice water in the inner pot is completely boiled, and the temperature of the inner pot rises at a speed lower than the limit speed, which is a stable state of the temperature of the inner pot. The inner pot is continuously heated, and when the water in the pot is less than a certain amount, the temperature of the inner pot rises at a faster rate. Before this, the heating may be stopped and the cooking process may be switched to the braising stage.
In one embodiment, as shown in fig. 2, determining whether the temperature in the cooking container enters a steady state according to the detected temperature of the cooking container may include the following steps.
In step S202, the temperature difference of the cooking container temperature in each detection period is calculated.
For example, during the cooking process, the temperature of the bottom of the pot is detected every preset duration, and the detected temperature is recorded. And subtracting the temperature at the beginning and the end of each detection period to obtain the temperature difference of the pot bottom temperature in each detection period. For example, the temperature detection is performed every m seconds. Such a case where the pot bottom temperature is detected at T0 at 0 seconds, T1 at m seconds, T2 at 2m seconds, T3 at 3m seconds, and T4 … … at 4m seconds can be calculated as the difference Δ T1 between the pot bottom temperatures in the period from 0 seconds to m seconds is T1-T0, the difference Δ T2 between the pot bottom temperatures in the period from m seconds to 2m seconds is T2-T1, the difference Δ T3 between the pot bottom temperatures in the period from 2m seconds to 3m seconds is T3-T2, the difference Δ T4 between the pot bottom temperatures in the period from 3m seconds to 4m seconds is T4-T3, and … … is T1
In step S204, it is determined whether the temperature in the cooking container enters a steady state according to the calculated temperature difference for the consecutive N detection periods.
Wherein N may be an integer greater than or equal to 3.
For example, the temperature differences of N consecutive detection periods are averaged, it is determined whether the resulting average is less than a preset average threshold, and if so, it is determined that the temperature in the cooking vessel enters a steady state.
In one embodiment, as shown in fig. 3, determining whether the temperature in the cooking container enters the steady state according to the calculated temperature difference for the consecutive N detection periods may include the following steps.
In step S302, the number of temperature differences smaller than a preset temperature difference threshold is determined among the temperature differences for N consecutive detection cycles.
In step S304, it is determined whether the determined number of temperature differences smaller than the preset temperature difference threshold is greater than or equal to a preset number threshold.
In step S306, it is determined that the temperature in the cooking container enters the steady state from the start time of the first detection period among the consecutive N detection periods when the determined number of temperature differences smaller than the preset temperature difference threshold is greater than or equal to the preset number threshold.
Wherein, the detection period can be any time length in the interval of [1 second, 10 seconds ]. The predetermined temperature difference threshold may be any temperature within the interval [0.01 ℃,0.5 ℃ ]. The predetermined number threshold may be N-1.
In an embodiment, the method of the present invention may further include: when it is determined that the temperature in the cooking container enters the steady state, the determination of whether the temperature in the cooking container enters the steady state is stopped.
For example, two factors of time and temperature change rate are used to control the conversion of the cooking process from the boiling stage to the stewing stage. The temperature detection is performed every m seconds. The pot bottom temperature is detected to be T0 at 0 second, T1 at m second, T2 at 2m second, T3 at 3m second and T4 at 4m second. It can be calculated that the temperature difference Δ T1 of the bottom temperature for the period of 0 to m seconds is T1-T0, the temperature difference Δ T2 of the bottom temperature for the period of m seconds to 2m seconds is T2-T1, the temperature difference Δ T3 of the bottom temperature for the period of 2 to 3m seconds is T3-T2, and the temperature difference Δ T4 of the bottom temperature for the period of 3 to 4m seconds is T4-T3. When at least 3 values of the delta T1, the delta T2, the delta T3 and the delta T4 are smaller than the set temperature difference threshold delta T, the temperature in the cooking container is judged to enter a stable state from 0 second, the temperature difference is stopped to be calculated, timing is started from 0 second, and the rice cooking process is controlled to be switched from a boiling stage to a stewing stage when the accumulated time reaches the preset time. When at least 3 values of the delta T1, the delta T2, the delta T3 and the delta T4 are not satisfied, temperature detection is continued, the pot bottom temperature is detected to be T5 at 5m seconds, the temperature difference delta T5 of the pot bottom temperature in the period from 4m seconds to 5m seconds is calculated to be T5-T4, whether at least 3 values of the delta T2, the delta T3, the delta T4 and the delta T5 are satisfied or not is judged to be less than the preset temperature difference threshold delta T, if so, the temperature in the cooking container is judged to enter a stable state from m seconds, the temperature difference is stopped to be calculated, the time is counted from m seconds, and the accumulated time reaches the preset time, and the cooking process is controlled to be switched from the boiling stage to the stewing stage. If the temperature difference is not satisfied, continuing temperature detection, detecting that the pot bottom temperature is T6 when the pot bottom temperature is 6m seconds, calculating the temperature difference delta T6 of the pot bottom temperature in the period from 6m seconds to 5m seconds to be T6-T5, judging whether at least 3 values of delta T3, delta T4, delta T5 and delta T6 are satisfied, wherein the temperature difference is less than a preset temperature threshold delta T, if so, judging that the temperature in the cooking container enters a stable state from 2m seconds, stopping calculating the temperature difference, starting timing from 2m seconds, and controlling the cooking process to be switched from a boiling stage to a stewing stage when the accumulated time reaches a preset time. If not, repeating the steps until at least 3 values of delta Ta, delta Ta +1, delta Ta +2 and delta Ta +3 are less than the preset temperature difference threshold value delta T.
In step S130, after the temperature in the cooking container enters a steady state, a timer is started.
For example, if it is determined that the cooking container temperature enters the steady state from the start time of the first detection period of the consecutive N detection periods, the time is counted from the start time of the first detection period of the consecutive N detection periods.
In step S140, when the counted time period reaches the preset time period, the cooking process is switched from the boiling stage to the braising stage by controlling the heater to stop heating.
Wherein the preset time period is inversely proportional to the specific heat capacity of the cooking container, the preset time period is inversely proportional to the thickness of the cooking container, or the preset time period is directly proportional to the cooking amount in the cooking container. The preset time duration can be any time duration in the interval of [0 second and 300 seconds ].
For example, the preset duration of the boiling stage is related to the thickness of the pot, the specific heat capacity of the material and the rice quantity, the thicker the pot, the smaller the preset duration, the larger the specific heat capacity, the smaller the preset duration, and the larger the rice quantity, the larger the preset duration.
For example, for the rice cooking process, the rice cooking stage can be changed into the stewing stage from the boiling stage by controlling the time length of the constant temperature rise stage of the inner pot. When the rice is cooked and enters the stable temperature state in the inner pot, timing is started, and when the timing duration reaches a preset duration value, the rice cooking process is controlled to be switched from a boiling stage to a stewing stage. Since the switching time point can be set before the conventional time point at which the set temperature T0 is detected by setting the preset time period, the heating time for the rice is shortened, and the control is accurate, preventing the rice at the bottom of the pot from being scorched.
The technical solution of the present invention is not limited to cooking, but can be applied to any cooking process deemed appropriate by those skilled in the art. Adopt technical scheme in this embodiment, can improve the accuracy nature to stage conversion control among the culinary art process, reduce the heat of culinary art container storage to the influence of culinary art, and then improve the culinary art quality.
