Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A slow stew control method of an electric cooker, a non-transitory computer-readable storage medium, and a slow stew control apparatus of an electric cooker proposed according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a slow stew control method of an electric cooker according to one embodiment of the present invention. As shown in fig. 1, the slow stewing control method comprises the following steps:
and S1, controlling the electric cooker to heat at the first power P1 when the electric cooker starts to cook until the electric cooker enters a slow stewing stage.
Further, in the embodiment of the present invention, when the electric cooker is controlled to heat at the first power P1, if the temperature inside the electric cooker reaches the first preset temperature T1 or the heating time of the electric cooker reaches the first preset time T1, the electric cooker is controlled to enter the slow stewing stage. The first preset temperature T1 and the first preset time T1 may be preset according to actual conditions. The first power P1 is the full power of the electric cooker.
And S2, controlling the electric cooker to alternately heat at the second power P2 and the third power P3 during the slow stewing stage so as to maintain the temperature in the electric cooker at a stable state. The second power P2 is greater than the third power P3, and the second power P2 is less than the first power P1.
And S3, detecting whether the electric cooker adds water or not.
And S4, if the electric cooker adds water, controlling the electric cooker to heat at a fourth power P4 until the temperature in the electric cooker reaches a first preset temperature T1. Wherein the fourth power P4 is greater than the second power P2.
Specifically, as shown in fig. 2, the slow stewing function of the electric cooker generally includes a warming phase and a slow stewing phase. When the electric cooker starts to cook, the temperature rising stage is firstly started, the electric cooker is controlled to heat at a first power P1 (full power) so as to heat food in the electric cooker, and when the temperature in the electric cooker reaches a first preset temperature T1 or the heating time of the electric cooker reaches a first preset time T1, the electric cooker is controlled to enter the slow stewing stage. That is, the slow stewing stage is started from the temperature rising stage, and the slow stewing stage can be shifted in time or temperature.
After the electric cooker enters the slow stewing stage, the electric cooker is controlled to alternately heat at the second power P2 and the third power P3 so as to maintain the temperature in the electric cooker within a certain range. Meanwhile, whether a user adds water into the electric cooker is detected in real time, if the user adds water into the electric cooker is detected, the temperature in the electric cooker is rapidly reduced (as the thickened part of the curve in fig. 2), in order to enable the temperature in the electric cooker to rapidly reach the first preset temperature T1 and ensure the cooking effect, the electric cooker enters a water adding stage, the electric cooker is controlled to heat with fourth power P4, and the electric cooker is controlled to enter a slow stewing stage after the temperature in the electric cooker reaches the first preset temperature T1. When the heating time of the electric cooker reaches the second preset time t2, the heating of the electric cooker is finished. Because the power of P4 is more than P2 is more than P3 and the power of P4 is higher, the temperature in the electric cooker can quickly reach the first preset temperature T1 in the water adding stage, so that enough heat can be kept in the slow stewing process, and the cooking effect is improved.
According to one embodiment of the invention, during the slow stewing stage, the electric cooker is controlled to heat at the second power P2, and if the temperature in the electric cooker reaches the second preset temperature T2, the electric cooker is controlled to heat at the third power P3. And if the temperature in the electric cooker is lower than the third preset temperature T3, controlling the electric cooker to heat at the second power P2, and repeating the steps. The second preset temperature T2 is greater than the third preset temperature T3, the second preset temperature T2 is greater than the first preset temperature T1, the first preset temperature T1, the second preset temperature T2 and the third preset temperature T3 may be preset according to actual conditions, for example, the first preset temperature T1 may be 90 ℃, the second preset temperature T2 may be 92 ℃, and the third preset temperature T3 may be 88 ℃.
Specifically, as shown in fig. 2, after the electric cooker enters the slow stewing stage, the electric cooker is controlled to heat at the second power P2, i.e. lower power, so that the food in the pot is kept for a period of time after reaching the first preset temperature T1 (e.g. 90 ℃) so that the food in the pot absorbs heat. During the slow stewing stage, if the temperature in the electric cooker reaches the second preset temperature T2 (for example, 92 ℃), the electric cooker is controlled to be heated at the third power P3, namely, the low power P3, so that the temperature in the electric cooker is slowly reduced. And if the temperature in the electric cooker is lower than the third preset temperature T3(88 ℃), controlling the electric cooker to heat at the second power P2, so that the temperature in the electric cooker slowly rises. Therefore, the temperature in the electric cooker can be maintained between the second preset temperature T2 and the third preset temperature T3, so that the temperature in the electric cooker is maintained in a stable state, and the cooking effect of slow stewing is ensured.
In the slow stewing process, whether a user adds water into the electric cooker or not is detected in real time, if the user is detected to add water into the electric cooker, the temperature in the electric cooker can be rapidly reduced, and in order to enable the temperature in the electric cooker to rapidly reach a first preset temperature T1, the electric cooker enters a water adding stage.
How to detect whether the electric cooker performs water addition is described below with reference to specific embodiments.
According to one embodiment of the invention, the detection of whether the electric cooker adds water comprises the following steps: acquiring a temperature reduction slope in the electric cooker, and judging whether the temperature reduction slope is greater than or equal to a preset value; and if the temperature drop slope is larger than or equal to the preset value, judging that the electric cooker adds water. The preset value can be preset according to actual conditions.
Specifically, as shown in fig. 2, if the user adds water to the electric cooker during the slow stewing process, the temperature of the electric cooker rapidly decreases (as shown by the bold portion of the curve in fig. 2), so that whether the electric cooker adds water can be detected by judging the temperature decrease slope, wherein the temperature decrease slope may be the ratio of the change value of the temperature within the preset time to the time. If the temperature drop slope is larger than the preset value, which indicates that the temperature in the electric cooker drops too fast, the user may add water to the electric cooker during the slow stewing process, and if the electric cooker is also heated at the second power P2 and the third power P3, the temperature in the electric cooker needs a longer time to reach the first preset temperature T1, and the cooking effect is affected. Therefore, the electric cooker is controlled to heat at the fourth higher power P4 so that the temperature in the electric cooker quickly reaches the first preset temperature T1 to ensure the cooking effect. And controlling the electric cooker to enter a slow stewing stage after the temperature in the electric cooker reaches the first preset temperature T1.
In summary, according to the slow stewing control method of the electric cooker in the embodiment of the invention, when the electric cooker starts to cook, the electric cooker is controlled to heat at the first power until the electric cooker enters the slow stewing stage, and in the slow stewing stage, the electric cooker is controlled to heat at the second power and the third power alternately to maintain the temperature in the electric cooker in a stable state, and then whether the electric cooker adds water is detected, and if the electric cooker adds water, the electric cooker is controlled to heat at the fourth power until the temperature in the electric cooker reaches the first preset temperature. Therefore, when water is added in the slow stewing process of the electric cooker, the method can ensure that the temperature in the electric cooker quickly reaches the temperature suitable for slow stewing by changing the heating power, ensure that enough heat is kept in the slow stewing process and improve the cooking effect.
To achieve the above object, the present invention also proposes a non-transitory computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the above slow stew control method of an electric cooker.
The non-transitory computer readable storage medium of the embodiment of the invention controls the electric cooker to heat at the first power when the electric cooker starts to cook until the electric cooker enters the slow stewing stage, controls the electric cooker to heat at the second power and the third power alternately to maintain the temperature in the electric cooker in a stable state during the slow stewing stage, then detects whether the electric cooker adds water, and controls the electric cooker to heat at the fourth power until the temperature in the electric cooker reaches the first preset temperature if the electric cooker adds water. Therefore, when water is added in the slow stewing process of the electric cooker, the temperature in the electric cooker can quickly reach the temperature suitable for slow stewing by changing the heating power, so that enough heat can be kept in the slow stewing process, and the cooking effect is improved.
Fig. 3 is a block schematic diagram of a slow fire control device of an electric cooker according to one embodiment of the present invention. As shown in fig. 3, the slow stewing control device includes: a temperature acquisition module 10, a control module 20, and a detection module 30.
Wherein, the temperature obtaining module 10 is used for obtaining the temperature in the electric cooker. The control module 20 is used for controlling the electric cooker to heat at the first power P1 when the electric cooker starts to cook until the electric cooker enters a slow stewing stage, and controlling the electric cooker to heat alternately at the second power P2 and the third power P3 during the slow stewing stage so as to maintain the temperature in the electric cooker in a stable state. The second power P2 is greater than the third power P3, and the second power P2 is less than the first power P1. The detection module 30 is used for detecting whether the electric cooker adds water. The control module 20 is further configured to control the electric cooker to heat at a fourth power P4 when the electric cooker adds water until the temperature inside the electric cooker reaches a first preset temperature T1. Wherein the fourth power P4 is greater than the second power P2.
Further, the control module 20 is also used for controlling the electric cooker to enter the slow stewing stage if the temperature in the electric cooker reaches the first preset temperature T1 or the heating time of the electric cooker reaches the first preset time T1 while controlling the electric cooker to heat at the first power P1.
Specifically, as shown in fig. 2, the slow stewing function of the electric cooker generally includes a warming phase and a slow stewing phase. When the electric cooker starts to cook, a temperature rising stage is firstly started, the control module 20 controls the electric cooker to heat with a first power P1 (full power) so as to heat food in the electric cooker, the temperature obtaining module 10 obtains the temperature in the electric cooker in real time, and when the temperature in the electric cooker reaches a first preset temperature T1 or the heating time of the electric cooker reaches a first preset time T1, the control module 20 controls the electric cooker to enter a slow stewing stage. That is, the slow stewing stage is started from the temperature rising stage, and the slow stewing stage can be shifted in time or temperature.
After the electric cooker enters the slow stewing stage, the control module 20 controls the electric cooker to alternately heat at the second power P2 and the third power P3 so as to maintain the temperature in the electric cooker within a certain range. Meanwhile, the detection module 30 detects whether the user adds water into the electric cooker in real time, if the detection module 30 detects that the user adds water into the electric cooker, the temperature in the electric cooker will drop rapidly (as the bold part of the curve in fig. 2), in order to make the temperature in the electric cooker reach the first preset temperature T1 rapidly to ensure the cooking effect, the electric cooker enters the water adding stage, the control module 20 controls the electric cooker to heat with the fourth power P4 until the temperature in the electric cooker reaches the first preset temperature T1, and then controls the electric cooker to enter the slow stewing stage. When the heating time of the electric cooker reaches the second preset time t2, the heating of the electric cooker is finished. Because the power of P4 is more than P2 is more than P3 and the power of P4 is higher, the temperature in the electric cooker can quickly reach the first preset temperature T1 in the water adding stage, so that enough heat can be kept in the slow stewing process, and the cooking effect is improved.
According to an embodiment of the present invention, during the slow stewing phase, the control module 20 is further configured to control the electric cooker to heat at the second power P2, control the electric cooker to heat at the third power P3 if the temperature inside the electric cooker reaches the second preset temperature T2, and control the electric cooker to heat at the second power P2 if the temperature inside the electric cooker is lower than the third preset temperature T3, and so on, wherein the second preset temperature T2 is greater than the third preset temperature T3 and the second preset temperature T2 is greater than the first preset temperature T1. The first preset temperature T1, the second preset temperature T2 and the third preset temperature T3 may be preset according to actual situations, for example, the first preset temperature T1 may be 90 ℃, the second preset temperature T2 may be 92 ℃ and the third preset temperature T3 may be 88 ℃.
Specifically, as shown in fig. 2, after the electric cooker enters the slow stewing stage, the control module 20 controls the electric cooker to heat at the second power P2, i.e., a lower power, so that the food in the pot is maintained for a period of time after reaching the first preset temperature T1 (e.g., 90 ℃) so that the food in the pot absorbs heat. During the slow stewing stage, if the temperature in the electric cooker reaches the second preset temperature T2 (e.g. 92 ℃), the control module 20 controls the electric cooker to heat at the third power P3, i.e. the low power P3, so as to slowly decrease the temperature in the electric cooker. And if the temperature in the electric cooker is lower than the third preset temperature T3(88 ℃), the module 20 controls the electric cooker to heat at the second power P2, so that the temperature in the electric cooker slowly rises. Therefore, the temperature in the electric cooker can be maintained between the second preset temperature T2 and the third preset temperature T3, so that the temperature in the electric cooker is maintained in a stable state, and the cooking effect of slow stewing is ensured.
In the slow stewing process, whether a user adds water into the electric cooker or not is detected in real time through the detection module 30, if the user is detected to add water into the electric cooker, the temperature in the electric cooker can be rapidly reduced, and in order to enable the temperature in the electric cooker to rapidly reach the first preset temperature T1, the electric cooker enters a water adding stage.
How the detection module 30 detects whether the electric cooker is to be filled with water is described below with reference to specific embodiments.
According to an embodiment of the present invention, as shown in fig. 4, the detection module 30 may include: an acquisition unit 301, a judgment unit 302, and a detection unit 303.
Wherein, the obtaining unit 301 is used for obtaining the temperature drop slope in the electric cooker. The determining unit 302 is configured to determine whether a temperature decrease slope is greater than or equal to a preset value. The detection unit 303 is used for judging that the electric cooker adds water when the temperature drop slope is greater than or equal to a preset value. The preset value can be preset according to actual conditions.
Specifically, as shown in fig. 2, if the user adds water to the electric cooker during the slow stewing process, the temperature of the electric cooker may rapidly decrease (for example, the bold portion of the curve in fig. 2), so the detection module 30 may detect whether the electric cooker adds water by determining a temperature decrease slope, where the temperature decrease slope may be a ratio of a change value of the temperature within a preset time to the time, that is, the obtaining unit 301 may obtain the temperature decrease slope by obtaining the ratio of the change value of the temperature within the preset time to the time.
If the determining unit 302 determines that the slope of the temperature drop is greater than the preset value, which indicates that the temperature in the electric cooker drops too fast, the detecting unit 303 determines that the electric cooker adds water, and if the electric cooker is heated with the second power P2 and the third power P3, the temperature in the electric cooker may take a long time to reach the first preset temperature T1, which affects the cooking effect. Therefore, the control module 20 controls the electric cooker to heat at the fourth higher power P4 so that the temperature in the electric cooker quickly reaches the first preset temperature T1 to ensure the cooking effect. And controlling the electric cooker to enter a slow stewing stage after the temperature in the electric cooker reaches the first preset temperature T1.
According to the slow stewing control device of the electric cooker, the temperature in the electric cooker is obtained through the temperature obtaining module, the control module controls the electric cooker to heat at the first power when the electric cooker starts to cook until the electric cooker enters a slow stewing stage, the electric cooker is controlled to alternately heat at the second power and the third power in the slow stewing stage so that the temperature in the electric cooker is maintained in a stable state, the detection module detects whether the electric cooker adds water or not, and the control module controls the electric cooker to heat at the fourth power when the electric cooker adds water until the temperature in the electric cooker reaches the first preset temperature. Therefore, when water is added into the electric cooker in the slow stewing process, the device can rapidly reach the temperature suitable for slow stewing by changing the heating power, ensure that enough heat is kept in the slow stewing process, and improve the cooking effect.
In addition, the invention also provides an electric cooker which comprises the slow stewing control device of the electric cooker.
According to the electric cooker provided by the embodiment of the invention, through the slow stewing control device, when water is added in the slow stewing process, the temperature in the electric cooker can quickly reach the temperature suitable for slow stewing by changing the heating power, so that enough heat can be kept in the slow stewing process, and the cooking effect is improved.
