Description

Technical Field

[0001] The present application relates to the technical field of cooking anti - overflow control, and more specifically, to a cooking anti - overflow control method and system based on cloud user behavior analysis. Background Art

[0002] At present, the development of anti - overflow technology for pressure cookers has always centered around pressure control. Traditional mechanical pressure relief valves rely on preset pressure thresholds to passively release steam to prevent overflow. In recent years, smart pressure cookers have achieved active anti - overflow by integrating pressure sensors and foam monitoring modules. For example, when detecting the accumulation of foam at the initial stage of boiling, they can automatically trigger a gradient pressure relief strategy and prevent overflow by opening the solenoid valve to release the surface bubbles.

[0003] For example, patent application CN118436234A (application number: CN202310077592.6) provides a cooking control method for controlling the heating of a cooking appliance in a pressure - maintaining state. Specifically, it includes obtaining the pressure value inside the cooking appliance; in response to the obtained pressure value rising to a preset pressure value, the heating device stops heating, and the cooling device operates to dissipate heat from the heating device. By the above method, patent application CN118436234A can, in the pressure - maintaining state, detect the pressure value inside the cooking appliance and close the heating device and turn on the cooling device according to the detected pressure value, so that the pressure inside the cooking appliance does not exceed the pressure limit upper limit of the exhaust valve and prevent the soup from overflowing due to overpressure. However, the method in patent application CN118436234A cannot control the cooking appliance in combination with the user's behavior to prevent overflow, which may affect the user's cooking experience and may also affect the user's cooking progress.

[0030] Existing methods for preventing soup from overflowing cannot control the cooking appliance in combination with the user's behavior to prevent overflow, which may affect the user's cooking experience and may also affect the user's cooking progress.

[0031] For the above reasons, the embodiments of the present application provide a cooking anti-overflow control method based on cloud user behavior analysis. This method includes: obtaining, based on the Internet of Things, the sequential pressure values in the electric pressure cooker within a preset first time period from the start of heating to the preset first time period through a preset cooking program, and the operation record of the heating switch of the electric pressure cooker by the user; wherein, the operation record of the heating switch includes the operation information of the user on the heating switch, and the preset first time period includes the time period from the start of heating to the pressure stabilization of the electric pressure cooker through the preset cooking program; when the pressure value at any moment in the sequential pressure values is greater than or equal to the overflow pressure value, and the operation record of the heating switch of the electric pressure cooker by the user includes that the operation of stopping the heating of the electric pressure cooker exceeds the preset time length, an anti-overflow control program is added to the preset cooking program of the electric pressure cooker, and the anti-overflow control program is sent to the electric pressure cooker based on the Internet of Things to update the preset cooking program of the electric pressure cooker; wherein, the anti-overflow control program is used to control the electric pressure cooker to stop heating for a preset second time period when the pressure value of the electric pressure cooker is greater than or equal to the overflow pressure value, and to control the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker is reduced by a preset adjustment pressure value. The method in the embodiments of the present application can judge the anti-overflow state in combination with the user's behavior, and then perform automatic anti-overflow control in the subsequent cooking process, which can improve the anti-overflow control effect of the electric pressure cooker.

[0032] In some scenarios, a cooking anti-overflow control method based on cloud user behavior analysis in the embodiments of the present application can be applied to the anti-overflow control of an electric pressure cooker, which can actively control the anti-overflow during the process of cooking different ingredients in the electric pressure cooker, and is suitable for the cooking habits of users, improving the cooking effect of the electric pressure cooker.

[0033] The following specifically describes a cooking anti-overflow control method based on cloud user behavior analysis provided by the embodiments of the present application with specific examples.

[0034] Figure 1 It is a schematic flow chart of the first cooking anti-overflow control method based on cloud user behavior analysis provided by the embodiments of the present application. As Figure 1 shown, the above method includes S110 to S120. The following specifically describes S110 to S120.

[0035] S110. Obtain, based on the Internet of Things, the sequential pressure values in the electric pressure cooker within a preset first time period from the start of heating to the preset first time period through a preset cooking program, and the operation record of the heating switch of the electric pressure cooker by the user. Wherein, the operation record of the heating switch includes the operation information of the user on the heating switch, and the preset first time period includes the time period from the start of heating to the pressure stabilization of the electric pressure cooker through the preset cooking program.

[0036] In the embodiments of the present application, in order to perform anti-overflow control according to the user's behavior, the cooking parameters of the electric pressure cooker within the time period from the start of cooking through a preset cooking program can be obtained based on the Internet of Things. The temperature and pressure of the electric pressure cooker within the time period from the start of cooking through the preset cooking program are in a continuously increasing state. Then, the anti-overflow control of the electric pressure cooker is performed according to the cooking parameters of the electric pressure cooker within the time period from the start of cooking through the preset cooking program.

[0037] In terms of parameter selection, the cooking parameters of the electric pressure cooker within the time period from the start of cooking through the preset cooking program can include the cooking pressure. The cooking pressure can be the sequential pressure value in the electric pressure cooker within the preset first time period from the start of heating through the preset cooking program. The sequential pressure value is used to characterize the pressure in the electric pressure cooker in chronological order.

[0038] Exemplarily, the sequential pressure value can be detected by a pressure sensor on the valve of the electric pressure cooker. The sequential pressure value includes the pressure values corresponding to multiple moments in chronological order.

[0039] Exemplarily, the preset first time period includes the time period from the start of heating through the preset cooking program until the pressure is stable in the electric pressure cooker. The preset first time period can specifically be the temperature-raising and pressure-raising time period during the cooking of the electric pressure cooker.

[0040] Exemplarily, the preset first time period can be the time period consumed from the start of heating through the preset cooking program until the pressure reaches the preset pressurization temperature in the electric pressure cooker.

[0041] In order to perform anti-overflow control on the electric pressure cooker according to the user's behavior, the heating switch operation record of the user on the electric pressure cooker can also be obtained. The heating switch operation record characterizes the control behavior characteristics of the user on the electric pressure cooker.

[0042] Exemplarily, the heating switch operation record includes the operation information of the user on the heating switch. The heating switch operation record can specifically be the opening or closing of the heating function of the electric pressure cooker.

[0043] Exemplarily, the preset cooking program can be a preset cooking program selected by the user on the electric pressure cooker. The preset cooking program can specifically include multiple preset cooking programs for cooking specific ingredients.

[0044] S120. When the pressure value at any moment in the chronological pressure value is greater than or equal to the overflow pressure value, and the operation record of the heating switch of the electric pressure cooker by the user includes operating the electric pressure cooker to stop heating for more than a preset duration, an anti-overflow control program is added to the preset cooking program of the electric pressure cooker, and the anti-overflow control program is sent to the electric pressure cooker based on the Internet of Things to update the preset cooking program of the electric pressure cooker. Among them, the anti-overflow control program is used to control the electric pressure cooker to stop heating for a preset second period when the pressure value of the electric pressure cooker is greater than or equal to the overflow pressure value, and to control the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker decreases by a preset adjustment pressure value.

[0045] Figure 2 FIG. is a schematic workflow diagram of the first cooking anti-overflow control method based on cloud user behavior analysis provided by the embodiments of the present application. As Figure 2 shown, during the use of the electric pressure cooker, when the pressure value at any moment in the chronological pressure value is greater than or equal to the overflow pressure value, and the overflow pressure value is the pressure value at which the electric pressure cooker may overflow, it indicates that the electric pressure cooker may have an overflow phenomenon.

[0046] Exemplarily, the overflow pressure value can be obtained through the usage experimental data of the pressure cooker.

[0047] As Figure 2 shown, during the use of the electric pressure cooker, when the operation record of the heating switch of the electric pressure cooker by the user includes operating the electric pressure cooker to stop heating for more than a preset duration, it indicates that the user may have taken switch operations such as turning off the heating of the electric pressure cooker during the heating of the electric pressure cooker to avoid overflow, ensuring that the electric pressure cooker will not overflow during subsequent use.

[0048] As Figure 2 shown, when it is determined that the electric pressure cooker reaches the overflow pressure and the user may take measures to prevent overflow, in order to improve the user experience of using the electric pressure cooker, an anti-overflow control program can be added to the preset cooking program of the electric pressure cooker. The anti-overflow control program is used to control the electric pressure cooker to prevent overflow, and can send the anti-overflow control program to the electric pressure cooker based on the Internet of Things to update the preset cooking program of the electric pressure cooker.

[0049] When working, the anti-overflow control program is specifically used to control the electric pressure cooker to stop heating for a preset second period when the pressure value of the electric pressure cooker is greater than or equal to the overflow pressure value, so that the electric pressure cooker stops heating after reaching the possible overflow pressure to prevent overflow, and can control the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker decreases by a preset adjustment pressure value, so that the electric pressure cooker can maintain an appropriate pressure state to prevent overflow, avoid the overflow of the electric pressure cooker, do not require the user to perform active anti-overflow operations, and will not cause the pressure in the electric pressure cooker to drop too much and affect the normal cooking progress of the user, thus improving the use experience.

[0050] The beneficial effects of the above implementation method are that it can judge the anti-overflow state in combination with the user's behavior, and then perform automatic anti-overflow control during the subsequent cooking process, which can improve the anti-overflow control effect of the electric pressure cooker. It does not require the user to actively operate the anti-overflow of the electric pressure cooker, and will not cause the pressure in the electric pressure cooker to drop too much and affect the normal cooking progress of the user, thus improving the user experience.

[0051] In some implementation methods, the above method further includes S130 to S140, which will be specifically described below.

[0052] S130: Obtain cooking ingredient information through the preset cooking program of the electric pressure cooker, and obtain the overflow pressure value corresponding to the cooking ingredient information. Obtain the heating power value of the electric pressure cooker, and determine the overflow rate adjustment factor corresponding to the heating power value.

[0053] Figure 3 It is a schematic diagram of the working process of the second cooking anti-overflow control method provided by the embodiment of the present application based on cloud user behavior analysis. As Figure 3 shown, when preventing overflow of the electric pressure cooker, in order to further improve the anti-overflow control effect, anti-overflow can be carried out for different ingredients. Specifically, cooking ingredient information can be obtained through the preset cooking program of the electric pressure cooker, and the overflow pressure value corresponding to the cooking ingredient information can be obtained. The overflow pressure value corresponding to the cooking ingredient information can optimize the anti-overflow control for different cooking ingredients.

[0054] Exemplarily, the overflow pressure value corresponding to the cooking ingredient information can be based on parameters such as the moisture content, fiber strength, and starch content of the ingredient, establish a dynamic overflow pressure value database, and then the overflow pressure value corresponding to different cooking ingredient information can be obtained according to the dynamic overflow pressure value database.

[0055] Exemplarily, the user actively selects the ingredient type (such as meat, porridge, beans, etc.) through the control panel or the mobile application, and inputs the estimated weight or volume. The system calls the preset physical property database (such as viscosity, water content, heat conduction coefficient, etc.) according to the selected ingredient category of the user to match the corresponding overflow pressure value.

[0056] When performing anti-overflow control, the heating power value of the electric pressure cooker can also be obtained. Different heating power values of the electric pressure cooker will affect the possibility of overflow, so the overflow rate adjustment factor corresponding to the heating power value can be determined.

[0057] Exemplarily, the overflow rate adjustment factor corresponding to the heating power value can be determined by empirical values.

[0058] S140. Multiply the overflow pressure value by an overflow rate adjustment factor to adjust the overflow pressure value.

[0059] As Figure 3 shown, after obtaining the overflow pressure value and the overflow rate adjustment factor, the overflow pressure value can be multiplied by the overflow rate adjustment factor to adjust the overflow pressure value, so as to adjust the overflow effect according to different cooking ingredients and heating powers.

[0060] The beneficial effect of the above implementation method is to obtain the overflow pressure value corresponding to the cooking ingredient information, determine the overflow rate adjustment factor corresponding to the heating power value, and multiply the overflow pressure value by the overflow rate adjustment factor to adjust the overflow pressure value, thereby realizing the control effect of overflow according to different ingredients and heating powers.

[0061] In some implementation methods, in S120 above, an anti-overflow control program is added to the cooking control program of the electric pressure cooker, including S121 to S122. The following is a specific description of S121 to S122.

[0062] S121. Obtain cooking ingredient information through the preset cooking program of the electric pressure cooker, and obtain the heating power adjustment factor corresponding to the cooking ingredient information.

[0063] Figure 4 FIG. shows the working flow diagram of the third cooking anti-overflow control method provided by the embodiment of the present application based on cloud user behavior analysis. As Figure 4 shown, cooking ingredient information can be obtained through the preset cooking program of the electric pressure cooker, and the heating power adjustment factor corresponding to the cooking ingredient information can be obtained. The heating power adjustment factor is used to further adjust the heating power during the anti-overflow process according to the ingredient category.

[0064] Exemplarily, the user actively selects the ingredient type (such as meat, porridge, beans, etc.) through the control panel or the mobile application, and inputs the estimated weight or volume. The control system of the electric pressure cooker can call the preset physical property database (such as viscosity, water content, thermal conductivity, etc.) according to the ingredient category selected by the user, and match the corresponding heating power adjustment factor.

[0065] Exemplarily, for sticky ingredients that are prone to foaming (such as porridge and thick soup), the heating power adjustment factor can be set to 0.5 - 0.8 to reduce the heating power and reduce the violent boiling caused by local overheating and overflow.

[0066] Exemplarily, for ingredients with high water content (such as clear soup), due to the large evaporation amount, the heating power adjustment factor can be appropriately increased (such as 0.9 - 1.0) to avoid too long cooking time caused by too low power.

[0067] S122. In the anti-overflow control program, multiply the heating power value for controlling the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker drops by a preset adjustment pressure value by a heating power adjustment factor to adjust the heating power value for the electric pressure cooker to restart heating.

[0068] As Figure 4 shown, after obtaining the heating power adjustment factor corresponding to the cooking ingredient information, in the anti-overflow control program, the heating power value for controlling the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker drops by a preset adjustment pressure value can be multiplied by the heating power adjustment factor, so that when the electric pressure cooker restarts heating, anti-overflow control can be performed according to the heating powers of different ingredients, to avoid overflow caused by heating different ingredients at the same restart heating power, and the accuracy of adjusting the heating power value for the electric pressure cooker to restart heating is achieved.

[0069] Exemplarily, multiply the standard heating power value (for example, 1000 W) by the heating power adjustment factor to generate a heating instruction adapted to the current ingredient. For example, if the adjustment factor corresponding to the porridge ingredient is detected to be 0.7, the actual restart heating power is adjusted to 700 W.

[0070] The beneficial effect of the above implementation is that when the electric pressure cooker restarts heating, anti-overflow control can be performed according to the heating powers of different ingredients, to avoid overflow caused by heating different ingredients at the same restart heating power, and the anti-overflow control effect of the electric pressure cooker is improved.

[0071] In some implementation manners, the above method further includes S150 to S160, and the following is a specific description of S150 to S160.

[0072] S150. Obtain cooking ingredient information through a preset cooking program of the electric pressure cooker, and obtain a preset adjustment pressure value corresponding to the cooking ingredient information. Obtain the atmospheric pressure value of the area where the electric pressure cooker is located, and obtain a pressure adjustment coefficient corresponding to the atmospheric pressure value.

[0073] In this implementation manner, multi-dimensional parameter matching can be further implemented through the preset cooking program of the electric pressure cooker to improve the anti-overflow control effect. During anti-overflow control, specifically, cooking ingredient information can be obtained through the preset cooking program of the electric pressure cooker, and a preset adjustment pressure value corresponding to the cooking ingredient information can be obtained. The preset adjustment pressure value is the pressure dropped by the electric pressure cooker during anti-overflow control, so as to improve the anti-overflow control effect of the electric pressure cooker.

[0074] Exemplarily, since porridge ingredients have a high viscosity and are easy to foam, the preset adjustment pressure value can be set to a higher value (for example, 5 kPa); since bean ingredients need to maintain full boiling, the preset adjustment pressure value is adjusted to a lower value (for example, 10 kPa).

[0075] In order to further improve the anti-overflow control effect, the atmospheric pressure value of the area where the electric pressure cooker is located can be obtained, and the pressure adjustment coefficient corresponding to the atmospheric pressure value can be obtained.

[0076] Exemplarily, the local atmospheric pressure value can be obtained in real time through a built-in air pressure sensor. The detected local atmospheric pressure value can be 70 kPa corresponding to a high altitude area and 101 kPa corresponding to a plain area.

[0077] S160. In the anti-overflow control program, multiply the preset adjustment pressure value for controlling the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker drops by the preset adjustment pressure value by the pressure adjustment coefficient, so as to adjust the preset adjustment pressure value for the electric pressure cooker to restart heating.

[0078] In the anti-overflow control program, by making the pressure value of the electric pressure cooker drop by the preset adjustment pressure value, the pressure inside the electric pressure cooker can be effectively reduced, so that the electric pressure cooker can prevent overflow during subsequent cooking.

[0079] At the same time, the preset adjustment pressure value for controlling the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker drops by the preset adjustment pressure value can be obtained, and the preset adjustment pressure value is multiplied by the pressure adjustment coefficient, so as to adjust the preset adjustment pressure value for the electric pressure cooker to restart heating according to the atmospheric pressure.

[0080] In this implementation manner, the calculation formula for the adjusted preset adjustment pressure value can be:

[0081] Pa = Pbase × α × β

[0082] Wherein, Pa represents the adjusted preset adjustment pressure value, Pbase represents the preset adjustment pressure value, α represents the pressure adjustment coefficient, and β represents the atmospheric pressure adjustment coefficient.

[0083] The beneficial effect of the above implementation manner is that the preset adjustment pressure value corresponding to the cooking ingredient information is obtained, the preset adjustment pressure value is the pressure dropped by the electric pressure cooker in anti-overflow control, and the pressure adjustment coefficient corresponding to the atmospheric pressure value is obtained. Multiply the preset adjustment pressure value for controlling the electric pressure cooker to restart heating after the pressure value of the electric pressure cooker drops by the preset adjustment pressure value by the pressure adjustment coefficient, which can further improve the anti-overflow control effect on the electric pressure cooker.

[0084] Figure 5 This is a schematic flowchart of the second cooking anti-overflow control method based on cloud user behavior analysis provided by the embodiments of the present application. As Figure 5 shown, the above method further includes S210 to S220, and the following is a specific description of S210 to S220.

[0085] S210. When the pressure value at any moment in the timing pressure value corresponding to the preset cooking program is greater than or equal to the overflow pressure value, and when the pressure value at any moment in the timing pressure value reaches the pressure value when the electric pressure cooker opens the lid, mark the timing pressure value as the user-intervened timing pressure value.

[0086] In this implementation, the intelligent decision-making can also be realized by dynamically monitoring the pressure timing data to improve the anti-overflow control effect. Specifically, when the pressure value at any moment in the timing pressure value corresponding to the preset cooking program is greater than or equal to the overflow pressure value, and when the pressure value at any moment in the timing pressure value reaches the pressure value when the electric pressure cooker opens the lid, it indicates that the pressure in the electric pressure cooker reaches the possible overflow pressure, and the user may manually open the lid of the electric pressure cooker to handle the overflow in the pot at this time. At this time, the timing pressure value can be marked as the user-intervened timing pressure value, and the user-intervened timing pressure value means that the timing pressure value is the timing pressure value intervened by the user.

[0087] Exemplarily, when it is detected that the pressure value in the pot reaches the pressure value Popen (which can be 4 kPa) when the electric pressure cooker opens the lid, and the pressure in the pot reaches the pressure value when the electric pressure cooker opens the lid and lasts for more than 3 seconds, the timing pressure value can be marked as the user-intervened timing pressure value, and at the same time, the state sensor of the lid can be combined to verify the open state of the lid.

[0088] S220. In response to the marked user-intervened timing pressure value, the electric pressure cooker does not trigger the anti-overflow control program.

[0089] When performing anti-overflow control on the electric pressure cooker, when the user-intervened timing pressure value is detected, the system can execute the control strategy of not triggering the anti-overflow control program for the electric pressure cooker at this time, thereby avoiding triggering the anti-overflow control program when the user-intervened timing pressure value is detected, and further affecting the cooking progress of the electric pressure cooker due to the anti-overflow control program.

[0090] The beneficial effect of the above implementation is that it allows the user to open the lid midway without interrupting the cooking process, improving the convenience of user operation and enhancing the user experience.

[0091] The beneficial effect of the above implementation is also that by recording the user-intervened timing pressure value corresponding to the user intervention mode, the control system of the electric pressure cooker can automatically optimize the control program, and can avoid affecting the cooking progress of the electric pressure cooker.

[0092] In some implementations, the above method further includes S230 to S240, and the following specifically describes S230 to S240.

[0093] S230. Count the user intervention statistical times corresponding to the user-intervened timing pressure value.

[0094] In this implementation manner, the quantitative analysis of user intervention behavior can be realized through a built-in counter. Specifically, the user intervention statistical times corresponding to the user intervention time-series pressure value can be counted. The larger the user intervention statistical times, the greater the number of times the user actively opens the pot lid to prevent overflow. Furthermore, the anti-overflow control of the electric pressure cooker can be optimized according to the user intervention statistical times.

[0095] S240. When the user intervention statistical times is greater than or equal to the preset user intervention statistical times, an anti-overflow control program is added to the preset cooking program of the electric pressure cooker, and the anti-overflow control program is sent to the electric pressure cooker based on the Internet of Things to update the preset cooking program of the electric pressure cooker, and a prompt message for prompting that the anti-overflow control program has been added is sent.

[0096] After obtaining the user intervention statistical times, when the user intervention statistical times is greater than or equal to the preset user intervention statistical times, it indicates that the number of times the user actively intervenes in the cooking process of the electric pressure cooker to prevent overflow is large. At this time, an anti-overflow control program can be added to the preset cooking program of the electric pressure cooker, and the anti-overflow control program is sent to the electric pressure cooker based on the Internet of Things to update the preset cooking program of the electric pressure cooker, and a prompt message for prompting that the anti-overflow control program has been added is sent to improve the anti-overflow control effect of the electric pressure cooker.

[0097] Exemplarily, when adding an anti-overflow control program to the preset cooking program of the electric pressure cooker, the anti-overflow control program can be added to the preset cooking program of the electric pressure cooker by the method in S120 above.

[0098] The beneficial effect of the above implementation manner is that when the number of times the user actively intervenes in the cooking process of the electric pressure cooker to prevent overflow is large, an anti-overflow control program can be added to the preset cooking program of the electric pressure cooker, and the electric pressure cooker can be actively anti-overflowed according to the user's behavior further to improve the anti-overflow effect of the electric pressure cooker.

[0099] In some implementation manners, the above method further includes S250 to S260, and the following specifically describes S250 to S260.

[0100] S250. Obtain the user operation feedback information corresponding to the user intervention time-series pressure value. Among them, the user operation feedback information is obtained by the user inputting through the input button on the electric pressure cooker, and the user operation feedback information includes the user adding ingredients to the electric pressure cooker.

[0101] In this implementation manner, user behavior data collection can be further achieved through a hardware interaction interface to optimize the anti-overflow control. Specifically, user operation feedback information corresponding to the user intervention time-series pressure value can be obtained, and the user operation feedback information is input through the input button on the electric pressure cooker. The user operation feedback information includes that the user adds ingredients to the electric pressure cooker. Furthermore, it can be determined whether the user has performed the anti-overflow operation of opening the lid of the electric pressure cooker by whether the user adds ingredients to the electric pressure cooker.

[0102] Exemplarily, a dedicated feedback button (physical button or capacitive touch button) can be set on the control panel of the electric pressure cooker, and a feeding confirmation icon is marked on the surface of the button.

[0103] S260: When the user operation feedback information is not to prevent overflow by opening the lid of the electric pressure cooker, the user intervention time-series pressure value is not included in the user intervention statistical count.

[0104] When the user operation feedback information is not to prevent overflow by opening the lid of the electric pressure cooker, it means that the user is only adding ingredients to the electric pressure cooker and not performing the anti-overflow operation of opening the lid of the electric pressure cooker. At this time, the user intervention time-series pressure value can be not included in the user intervention statistical count to avoid affecting the anti-overflow control effect of the electric pressure cooker.

[0105] The beneficial effect of the above implementation manner is that when the user operation feedback information is not to prevent overflow by opening the lid of the electric pressure cooker, the user intervention time-series pressure value is not included in the user intervention statistical count, which can avoid actively performing anti-overflow on the electric pressure cooker according to the user's behavior when the user adds ingredients to the electric pressure cooker, and improves the anti-overflow control effect of the electric pressure cooker.

[0106] Figure 6 FIG. is a schematic flowchart of the third cooking anti-overflow control method based on cloud user behavior analysis provided by the embodiment of the present application. As Figure 6 shown, the above method further includes S310 to S320, and the following is a specific description of S310 to S320.

[0107] S310: When the pressure value at any moment in the time-series pressure value reaches the pressure value when the lid of the electric pressure cooker is opened, and the user operation feedback information is to prevent overflow by opening the lid of the electric pressure cooker, obtain the subsequent time-series pressure values within the preset interval period after the user closes the electric pressure cooker again. Wherein, the duration of the preset interval period is determined according to the heating power of the electric pressure cooker.

[0108] In this implementation mode, the pressure state after the user closes the lid of the electric pressure cooker can be detected, so as to further implement anti-overflow control according to the pressure state after the lid of the electric pressure cooker is closed. When the pressure value at any moment in the sequential pressure values reaches the pressure value when the lid of the electric pressure cooker is opened, and the user operation feedback information is to prevent overflow by opening the lid of the electric pressure cooker, it indicates that the user has opened the lid to prevent overflow. At this time, the subsequent sequential pressure values within the preset interval after the user closes the electric pressure cooker again can be obtained, and the anti-overflow during subsequent cooking can be optimized and controlled. Among them, the preset interval is the pressure value required for the pressure inside the electric pressure cooker to rise.

[0109] It should be noted that the duration of the preset interval is determined according to the heating power of the electric pressure cooker. When the heating power of the electric pressure cooker is larger, the preset interval is shorter; when the heating power of the electric pressure cooker is smaller, the preset interval is longer; thus, it is possible to avoid increasing the calculation burden in anti-overflow control due to too long pressure monitoring time inside the electric pressure cooker.

[0110] Exemplarily, the user operation feedback information can be input through the input button on the electric pressure cooker, and it can be determined whether the user operation feedback information is to prevent overflow by opening the lid of the electric pressure cooker.

[0111] S320. Determine the subsequent pressure increment value corresponding to each moment in the subsequent sequential pressure values. When the first subsequent pressure value corresponding to the first moment is greater than or equal to the preset subsequent pressure value, and the first subsequent pressure increment value corresponding to the first moment is greater than or equal to the preset subsequent pressure increment value, the electric pressure cooker triggers the anti-overflow control program to prevent overflow of the electric pressure cooker. Among them, the preset subsequent pressure increment value is determined by the cooking ingredient information.

[0112] In this implementation mode, the subsequent pressure increment value corresponding to each moment in the subsequent sequential pressure values can be further determined. The subsequent pressure increment value represents the pressure increase rate inside the electric pressure cooker at each moment. When the first subsequent pressure value corresponding to the first moment is greater than or equal to the preset subsequent pressure value, and the first subsequent pressure increment value corresponding to the first moment is greater than or equal to the preset subsequent pressure increment value, it indicates that the pressure inside the electric pressure cooker is too high, and at this time, the pressure increase rate inside the electric pressure cooker is too high. At this time, the electric pressure cooker can be controlled to trigger the anti-overflow control program to prevent overflow of the electric pressure cooker.

[0113] It should be noted that the preset subsequent pressure increment value is determined by the cooking ingredient information, so that anti-overflow can be carried out for a specific pressure increase rate according to the cooking ingredients of different electric pressure cookers, so as to improve the anti-overflow control effect.

[0114] The beneficial effect of the above implementation is that when the user operation feedback information is to prevent overflow by opening the lid of the electric pressure cooker, when the first subsequent pressure increment value corresponding to the first moment after the user closes the lid is greater than or equal to the preset subsequent pressure increment value, the electric pressure cooker triggers the anti-overflow control program to prevent overflow of the electric pressure cooker, which can prevent overflow of the electric pressure cooker in advance and improve the anti-overflow control effect.

[0115] In some implementations, the above method further includes S410 to S420, which are specifically described below.

[0116] S410. After sending the anti-overflow control program to the electric pressure cooker based on the Internet of Things to update the cooking program of the electric pressure cooker, re-obtain the updated timing pressure value in the electric pressure cooker from the start of heating to the preset first time period and the user's heating switch operation record of the electric pressure cooker based on the Internet of Things.

[0117] In this implementation, after sending the anti-overflow control program to the electric pressure cooker based on the Internet of Things to update the cooking program of the electric pressure cooker, the anti-epidemic control effect of the electric pressure cooker can be further monitored based on the Internet of Things. When monitoring, the updated timing pressure value in the electric pressure cooker from the start of heating to the preset first time period and the user's heating switch operation record of the electric pressure cooker can be re-obtained based on the Internet of Things. The preset first time period is the time period when the pressure in the electric pressure cooker rises, and the user's heating switch operation record records whether the user has performed an anti-overflow operation on the electric pressure cooker.

[0118] S420. Determine the updated pressure increment value corresponding to each moment in the updated timing pressure value. When the first updated pressure value corresponding to the first moment is greater than or equal to the preset pressure value, and the first updated pressure increment value corresponding to the first moment is greater than or equal to the preset updated pressure increment value, and the heating switch operation record includes the user operating the heating switch of the electric pressure cooker, the electric pressure cooker triggers the anti-overflow control program to prevent overflow of the electric pressure cooker. Among them, the preset pressure value is 60% to 80% of the overflow pressure value.

[0119] After obtaining the updated timing pressure value, the pressure change speed in the timing of the updated timing pressure value can be further determined to determine whether the pressure increase speed in the electric pressure cooker is too high. Specifically, the updated pressure increment value corresponding to each moment in the updated timing pressure value can be determined, and the anti-overflow process of the electric pressure cooker can be controlled according to the updated pressure increment value.

[0120] After obtaining the updated pressure increment value, when the first updated pressure value corresponding to the first moment is greater than or equal to the preset pressure value, the first updated pressure increment value corresponding to the first moment is greater than or equal to the preset updated pressure increment value, and the heating switch operation record includes the user's operation on the heating switch of the electric pressure cooker, it indicates that the pressure of the electric pressure cooker is too high at the first moment, and the pressure increase amplitude at the first moment is relatively large, and the user has performed an active anti-overflow operation on the electric pressure cooker. At this time, it shows that the anti-overflow control effect of the anti-overflow control program of the electric pressure cooker is not good. Furthermore, the electric pressure cooker can be further controlled through the program for anti-overflow control. Specifically, the electric pressure cooker can be controlled to trigger the anti-overflow control program to prevent overflow of the electric pressure cooker, so as to improve the anti-overflow control effect of the electric pressure cooker.

[0121] Exemplarily, the preset pressure value can be 60% to 80% of the overflow pressure value, so as to be able to prevent overflow of the electric pressure cooker in advance.

[0122] The beneficial effect of the above implementation manner is that after adding the anti-overflow control program to the electric pressure cooker, when the pressure of the electric pressure cooker is too high at the first moment, and the pressure increase amplitude at the first moment is relatively large, and the user has performed an active anti-overflow operation on the electric pressure cooker. At this time, it shows that the anti-overflow control effect of the anti-overflow control program of the electric pressure cooker is not good. At this time, the anti-overflow control program is triggered in advance to prevent overflow of the electric pressure cooker, improving the anti-overflow control effect of the electric pressure cooker.
