Description

Technical Field

[0001] The present application relates to the technical field of electric pressure cooker control, and more specifically, to a control method and system for an electric pressure cooker based on the Internet of Things. Background Art

[0002] Electric pressure cookers are a combination of traditional pressure cookers and rice cookers. Electric pressure cookers combine the advantages of pressure cookers and rice cookers. Electric pressure cookers use electric heating to quickly increase the temperature and pressure in the pot to achieve the purpose of cooking food. Electric pressure cookers usually have a variety of preset cooking modes for users to choose from. The heating element and electronic control device of the electric pressure cooker can control the pressure in the pot. When the pressure is too high, the electronic control device will turn off the fire to keep the pressure in the pot within a certain pressure range until the heating time of the electric pressure cooker stops. This design not only improves cooking efficiency, but also ensures safety in use.

[0003] At present, the control program of the electric pressure cooker generally requires manual control by the user, and some electric pressure cookers can realize automatic confirmation of the cooking program. For example, patent CN107957689B (application number: CN201610903752.8) provides a control method for an electric pressure cooker, wherein the electric pressure cooker detects a first operation and triggers the operation of a first cooking program; detects whether there is a trigger instruction that triggers the electric pressure cooker to switch from the first cooking program to a second cooking program; wherein the second cooking program is different from the first cooking program; determines whether to control the electric pressure cooker to switch from the first cooking program to the second cooking program based on the trigger instruction according to the detection result, and runs the second cooking program, so that the electric pressure cooker automatically switches from the first cooking program to the second cooking program during the operation of the first cooking program or after the operation of the first cooking program ends. The method in patent CN107957689B does not require manual control of the electric pressure cooker to automatically switch the cooking program, but it is difficult to meet the user's personalized cooking needs for the electric pressure cooker.

[0029] In the control method of the electric pressure cooker in the prior art, there is no need to manually control the electric pressure cooker to automatically switch the cooking program, but it is difficult to meet the user's personalized cooking needs for the electric pressure cooker. In particular, the cooking time of the electric pressure cooker is long. When the user has personalized needs for the cooking time, the existing control method of the electric pressure cooker is difficult to meet the personalized control of the electric pressure cooker.

[0030] Based on the above reasons, an embodiment of the present application provides a control method for an electric pressure cooker based on the Internet of Things, and the method includes: obtaining the user's cooking ingredient type, preset cooking time, and heating parameters of the electric pressure cooker based on the Internet of Things; determining multiple cooking programs according to the cooking ingredient type, preset cooking time, and heating parameters; wherein the sum of the cooking times corresponding to the multiple cooking programs is the preset cooking time; sending the multiple cooking programs to the electric pressure cooker based on the Internet of Things, and the electric pressure cooker sequentially executes the multiple cooking programs. The embodiment of the present application can determine multiple cooking programs according to the cooking ingredient type, the preset cooking time, and the heating parameters of the electric pressure cooker, and control the electric pressure cooker to cook according to the multiple cooking programs based on the Internet of Things, thereby realizing the planning of appropriate cooking time according to the cooking ingredient type and improving the degree of personalization of cooking according to the electric pressure cooker.

[0031] In some scenarios, a control method for an electric pressure cooker based on the Internet of Things of an embodiment of the present application can be applied to the control of an electric pressure cooker based on the Internet of Things control, and can plan the appropriate cooking time according to the type of cooking ingredients, thereby improving the degree of personalization of cooking in the electric pressure cooker.

[0032] The following is a detailed description of a control method for an electric pressure cooker based on the Internet of Things provided in an embodiment of the present application with reference to specific examples.

[0033] Figure 1 A flow chart of a control method of an electric pressure cooker based on the Internet of Things provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the control method of the electric pressure cooker based on the Internet of Things includes S110 to S130, and S110 to S130 are specifically described below.

[0034] S110: Obtain the user's cooking ingredient type, preset cooking time, and heating parameters of the electric pressure cooker based on the Internet of Things.

[0035] When the electric pressure cooker in the embodiment of the present application is in use, a corresponding electric pressure cooker control App can be configured on the mobile phone. The user can input the type of cooking ingredients and the preset cooking time on the electric pressure cooker control App, and obtain the heating parameters of the electric pressure cooker through the Internet of Things through the electric pressure cooker control App, so that the electric pressure cooker control App can centrally obtain the type of cooking ingredients, the preset cooking time and the heating parameters, and then the cooking process of the electric pressure cooker can be controlled by the type of cooking ingredients, the preset cooking time and the heating parameters.

[0036] S120: Determine multiple cooking programs according to the type of cooking ingredients, the preset cooking time and the heating parameters, wherein the sum of the cooking times corresponding to the multiple cooking programs is the preset cooking time.

[0037] Before the electric pressure cooker works, the type of cooking ingredients, preset cooking time and heating parameters can be sent to the server through the electric pressure cooker control App. The server can determine multiple cooking programs for cooking the ingredients based on the type of cooking ingredients, preset cooking time and heating parameters.

[0038] When determining multiple cooking programs, the sum of the cooking times corresponding to the multiple cooking programs is the preset cooking time, so that the cooking program can be personalized according to the user's preset cooking time, thereby improving the control effect of the cooking program of the electric pressure cooker. When formulating the cooking program, the cooking program of the ingredients can be optimized according to the type of ingredients, preset cooking time and heating parameters, thereby improving the cooking effect of the ingredients.

[0039] S130: sending multiple cooking programs to the electric pressure cooker based on the Internet of Things, and the electric pressure cooker executes the multiple cooking programs in sequence.

[0040] Before the electric pressure cooker works, multiple cooking programs can be sent to the electric pressure cooker based on the Internet of Things, so that the electric pressure cooker can execute multiple cooking programs in sequence when working to cook the ingredients.

[0041] Exemplarily, the plurality of cooking programs may include a temperature raising program, a high-fire cooking program, a low-fire slow-cooking program, and a warm keeping program.

[0042] The beneficial effect brought about by the above-mentioned implementation method is that a cooking program can be personalized according to the user's preset cooking time, thereby improving the personalized control effect of the cooking program of the electric pressure cooker.

[0043] The beneficial effect brought about by the above-mentioned implementation method is that when formulating a cooking program, the cooking program of the ingredients can be optimized according to the type of cooking ingredients, preset cooking time and heating parameters, thereby maximizing the cooking effect of the ingredients.

[0044] In some implementations, the method further includes: determining a minimum cooking time according to the type of cooking ingredients, and when the preset cooking time is less than the shortest cooking time, prompting the user to increase the preset cooking time. When the preset cooking time is greater than or equal to the shortest cooking time and less than the maximum cooking time, determining a time adjustment coefficient according to the ratio of the shortest cooking time to the preset cooking time, and determining multiple cooking programs according to the time adjustment coefficients.

[0045] When determining the cooking program of the electric pressure cooker, the shortest cooking time can be determined according to the type of cooking ingredients. When the preset cooking time is less than the shortest cooking time, it means that the cooking program for the corresponding type of ingredients cannot be planned within the preset cooking time set by the user (for example, the ingredients cannot be cooked within the shortest cooking time). At this time, the user can be prompted to increase the preset cooking time, so that the user can reasonably plan multiple cooking programs for cooking the ingredients after increasing the preset cooking time.

[0046] Exemplarily, the server may store different minimum cooking times for different types of ingredients.

[0047] When determining the cooking program of the electric pressure cooker, when the preset cooking time is greater than or equal to the shortest cooking time and less than the maximum cooking time, in order to optimize the cooking program of the ingredients according to the user's preset cooking time, the time adjustment coefficient can be determined according to the ratio of the shortest cooking time to the preset cooking time, and multiple cooking programs can be adjusted according to the time adjustment coefficient, thereby optimizing the cooking effect of the ingredients by adjusting multiple cooking programs according to the time adjustment coefficient.

[0048] The maximum cooking time corresponds to the maximum time that ingredients are cooked in an electric pressure cooker. If the maximum cooking time is exceeded, the cooking quality (such as taste) of the ingredients will be affected. Therefore, the cooking time of the ingredients can be controlled within the maximum cooking time.

[0049] Exemplarily, the server may store different maximum cooking times for different food types.

[0050] The beneficial effect brought about by the above-mentioned implementation method is that it can optimize multiple cooking programs for ingredients according to the relationship between the user's preset cooking time and the shortest cooking ingredient, and then adjust multiple cooking programs to optimize the cooking effect of the ingredients.

[0051] In some implementations, the above-mentioned determination of multiple cooking programs based on the time adjustment coefficient includes: determining multiple cooking programs and heating parameters corresponding to the cooking ingredient type based on the cooking ingredient type, obtaining the standard duration of each cooking program, multiplying the standard duration of each cooking program by the time adjustment coefficient to obtain the cooking time of each cooking program; and dividing the heating parameter by the time adjustment coefficient to obtain the heating parameter of each cooking program.

[0052] When planning multiple cooking programs for ingredients, you can determine multiple cooking programs corresponding to the cooking ingredient type according to the cooking ingredient type, and obtain the standard duration of each cooking program. Multiply the standard duration of each cooking program by the time adjustment coefficient to obtain the cooking time of each cooking program. You can then increase or shorten the standard time by multiplying the time adjustment coefficient to obtain the adjusted cooking time for each cooking program.

[0053] When planning multiple cooking programs for ingredients, after obtaining multiple cooking programs and heating parameters, each cooking program corresponds to a heating parameter. The heating parameter can also be divided by the time adjustment coefficient to obtain the heating parameter of each cooking program, so that the heating parameter can be adjusted after the cooking time is adjusted to ensure the stability of the cooking effect of the ingredients.

[0054] Exemplarily, the server can store the cooking ingredient type to determine the multiple cooking programs corresponding to the cooking ingredient type and the standard duration corresponding to each cooking program, and then can directly query the multiple cooking programs corresponding to the cooking ingredient type and the standard duration corresponding to each cooking program according to the cooking ingredient type.

[0055] Exemplarily, when the first cooking time of the first cooking program for cooking ingredients is T1, the first heating parameter of the first cooking program is K1, and the time adjustment coefficient is M, the first cooking time of the first cooking program is MT1 after adjustment, and the first heating parameter of the first cooking program is adjusted to K1 / M.

[0056] Exemplarily, the heating parameter corresponds to the heating power and control pressure of the food. When the first heating parameter of the first cooking program is adjusted to K1 / M, the heating power and control pressure can be adjusted at the same ratio at the same time.

[0057] The beneficial effect brought about by the above-mentioned implementation method is that when multiple cooking programs are adjusted to meet the user's preset cooking time, when the cooking time increases, the heating parameter is reduced accordingly, which can avoid overcooking and becoming too soft and mushy in the ingredients; when the cooking time is reduced, the heating parameter is increased accordingly, which can ensure that the ingredients are fully cooked.

[0058] In some implementations, the above method also includes: when the preset cooking time is greater than or equal to the maximum cooking time, the preset cooking time is divided into multiple cooking programs and a keeping warm program, the electric pressure cooker enters the keeping warm program after cooking according to the maximum time of each cooking program in the multiple cooking programs, and the heating parameters of each cooking program are the minimum heating parameters.

[0059] After the user sets the preset cooking time, when the preset cooking time is greater than or equal to the maximum cooking time, it means that the preset cooking time set by the user is too long. If the ingredients are cooked according to the preset cooking time, the ingredients may be overcooked. To avoid this situation, the preset cooking time can be divided into multiple cooking programs and a keeping warm program. In the keeping warm program, only the ingredients are kept warm. The electric pressure cooker enters the keeping warm program after cooking according to the maximum time of each cooking program in the multiple cooking programs, so that the cooking quality of the ingredients will not be affected after cooking.

[0060] When cooking ingredients according to the maximum duration of each cooking program, the heating parameter of each cooking program is the minimum heating parameter, thereby preventing the food from being too soft and mushy when cooking according to the maximum duration of each cooking program.

[0061] Exemplarily, the minimum heating parameter corresponding to the maximum duration of each cooking program may be preset, and the minimum heating parameter corresponds to the minimum heating power and minimum control pressure of the food.

[0062] When cooking according to the maximum duration of each cooking program among multiple cooking programs, a slower cooking speed for some ingredients can improve the flavor of the ingredients, and at the same time can avoid the ingredients from being cooked too soft due to the cooking temperature being too high, thereby improving the cooking quality of the ingredients.

[0063] The beneficial effect brought about by the above-mentioned implementation method is that when the preset cooking time set by the user is too long, the ingredients can be cooked according to the maximum time of each cooking program and the corresponding minimum heating parameters, so that some ingredients can be cooked more slowly through a slower cooking speed. The effect of slowly absorbing the flavor of the ingredients can be improved, and at the same time, the cooking temperature of the ingredients can be prevented from being too high, causing the ingredients to be cooked too soft.

[0064] In some implementations, Figure 2 A flow chart of another control method of an electric pressure cooker based on the Internet of Things provided in an embodiment of the present application is as follows: Figure 2 As shown, the above method further includes S210 to S220, and S210 to S220 are described in detail below.

[0065] S210. When the electric pressure cooker executes a plurality of cooking programs in sequence, a cooking adjustment instruction of the user is obtained.

[0066] During the cooking process of the electric pressure cooker, the electric pressure cooker sequentially executes multiple cooking programs and obtains a user's cooking adjustment instruction, thereby enabling the user to adjust the cooking process of the electric pressure cooker through the cooking adjustment instruction.

[0067] S220: When the preset cooking time is extended to the first time according to the cooking adjustment instruction, the remaining cooking time and the remaining total cooking time of each cooking program are obtained, the remaining cooking time of each cooking program is extended in proportion according to the ratio of the first time to the remaining total cooking time, and the maximum control pressure value of the electric pressure cooker is reduced in proportion according to the ratio of the first time to the remaining total cooking time. When the preset cooking time is shortened to the second time according to the cooking adjustment instruction, the remaining cooking time and the remaining total cooking time of each cooking program are obtained, the remaining cooking time of each cooking program is shortened in proportion according to the ratio of the remaining total cooking time to the second time, and the maximum control pressure value of the electric pressure cooker is increased in proportion according to the ratio of the remaining total cooking time to the second time, and the maximum control pressure value of the electric pressure cooker after the proportional increase is less than the designed maximum pressure value of the electric pressure cooker.

[0068] When the electric pressure cooker is in use, after obtaining the user's cooking adjustment instructions, when the preset cooking time is extended to the first time according to the cooking adjustment instructions, in order to adjust the cooking process of the electric pressure cooker, the remaining cooking time of each cooking program and the remaining total cooking time can be obtained. The remaining total cooking time is the total remaining time when the electric pressure cooker cooks according to multiple programs, and the remaining cooking time of each cooking program represents the remaining cooking time of each cooking program.

[0069] When adjusting multiple cooking programs of the electric pressure cooker, the ratio of the first time length to the remaining total cooking time can be calculated first, and the remaining cooking time of each cooking program can be extended in proportion according to the ratio of the first time length to the remaining total cooking time, so that the cooking time of each cooking program is extended, and the maximum control pressure value of the electric pressure cooker can be reduced in proportion according to the ratio of the first time length to the remaining total cooking time, so that the cooking control pressure can be reduced after the cooking time is extended. The cooking control pressure is the control pressure threshold of the electric pressure cooker, and the electric pressure cooker will control the pressure inside the electric pressure cooker near the cooking control pressure.

[0070] When in use, when the remaining cooking time of each cooking program is extended in proportion according to the ratio of the first time and the remaining total cooking time, the remaining cooking time of each cooking program, the ratio of the first time and the remaining total cooking time can be multiplied. Similarly, when the maximum control pressure value of the electric pressure cooker is reduced in proportion according to the ratio of the first time and the remaining total cooking time, the maximum control pressure value of the electric pressure cooker, the first time and the ratio of the remaining total cooking time can be multiplied.

[0071] Through the above process, the cooking time of each cooking program is extended and the cooking control pressure is reduced, which can improve the slow flavoring effect of some ingredients during cooking and prevent the ingredients from being cooked too soft.

[0072] When the electric pressure cooker is in use, when the preset cooking time is shortened to the second time according to the cooking adjustment instruction, if the cooking process of the electric pressure cooker needs to be accelerated, the remaining cooking time and the remaining total cooking time of each cooking program can be obtained, and then the cooking process of the electric pressure cooker can be adjusted according to the remaining cooking time of each cooking program and the remaining total cooking time.

[0073] When adjusting the cooking time of the electric pressure cooker, the ratio of the remaining total cooking time to the second time can be calculated first, and the remaining cooking time of each cooking program can be proportionally shortened according to the ratio of the remaining total cooking time to the second time, and the maximum control pressure value of the electric pressure cooker can be proportionally increased according to the ratio of the remaining total cooking time to the second time. The maximum control pressure value of the electric pressure cooker after the proportional increase is less than the designed maximum pressure value of the electric pressure cooker.

[0074] When in use, when the remaining cooking time of each cooking program is proportionally shortened according to the ratio of the remaining total cooking time to the second time, the remaining cooking time of each cooking program and the ratio of the remaining total cooking time to the second time can be multiplied. Similarly, when the maximum control pressure value of the electric pressure cooker is proportionally increased according to the ratio of the remaining total cooking time to the second time, the maximum control pressure value of the electric pressure cooker and the ratio of the remaining total cooking time to the second time can be multiplied.

[0075] Through the above process, the cooking time of each cooking program is shortened, and the cooking control pressure is increased, which can ensure that the cooking time of the ingredients is shortened and the food is fully cooked.

[0076] When the electric pressure cooker is in use, the maximum control pressure value of the electric pressure cooker after proportional increase is less than the designed maximum pressure value of the electric pressure cooker, which can ensure the safety of the electric pressure cooker when in use.

[0077] The beneficial effect brought by the above implementation method is that when the user adjusts the cooking time according to his own schedule, the cooking program of the electric pressure cooker can be adjusted accordingly to achieve the best cooking effect. When the cooking time is extended, the slow flavoring effect of some ingredients during cooking can be improved, and the ingredients can be prevented from being cooked too soft. When the cooking time is shortened, the cooking time of the ingredients can be effectively controlled and shortened, and the food can be fully cooked.

[0078] In some implementations, the above method also includes: when the preset cooking time is extended to the first time according to the cooking adjustment instruction, and the electric pressure cooker has entered the keep warm program, the difference between the first time and the preset cooking time is calculated to obtain the time extension value, and the time extension value is added to the keep warm time corresponding to the keep warm program of the electric pressure cooker.

[0079] When the electric pressure cooker is in use, when the preset cooking time is extended to the first time according to the cooking adjustment instruction, and the electric pressure cooker has entered the keep warm program, it means that the electric pressure cooker has completed the main cooking program of the electric pressure cooker. At this time, in order to ensure that the preset cooking time of the electric pressure cooker ensures the stability of the food temperature after the extension, the difference between the first time and the preset cooking time can be calculated to obtain the time extension value, and the time extension value can be added to the keep warm time corresponding to the keep warm program of the electric pressure cooker, which can ensure that the electric pressure cooker can effectively keep the food warm.

[0080] The beneficial effect brought about by the above-mentioned implementation method is that after the preset cooking time is extended to the first time according to the cooking adjustment instruction, in order to ensure that the temperature of the food is stable after the preset cooking time of the electric pressure cooker is extended, the insulation time of the electric pressure cooker can be extended, thereby ensuring that the electric pressure cooker can effectively keep the food warm.

[0081] The beneficial effect brought about by the above-mentioned implementation method is that after extending the preset cooking time to the first time according to the cooking adjustment instruction, the insulation time of the electric pressure cooker is extended by active control, which can provide users with a more intuitive and convenient operation experience and enhance the user-friendliness of the product.

[0082] In some implementations, the above method also includes: when the pressure cooking program for heating and pressurizing is at the end, obtaining the pressure detection value of the electric pressure cooker, and when the first pressure detection value is less than the preset pressure value, increasing the pressurization time corresponding to the pressure cooking program by a unit time until the pressure detection value of the electric pressure cooker is greater than or equal to the second pressure value.

[0083] When the electric pressure cooker is working, the food in the electric pressure cooker needs to be heated from room temperature to a high temperature and high pressure state. When the pressure cooking program for heating and pressurization is over, the pressure detection value of the electric pressure cooker can be obtained. When the first pressure detection value is less than the preset pressure value, it means that the electric pressure cooker has not achieved the heating and pressurization effect after the pressure cooking program is over. In order to ensure that the electric pressure cooker achieves the heating and pressurization effect, the pressurization time corresponding to the pressure cooking program can be increased by a unit time until the pressure detection value of the electric pressure cooker is greater than or equal to the preset pressure value to ensure the cooking effect of the subsequent high temperature and pressure keeping program.

[0084] Exemplarily, when the pressure cooking program of the electric pressure cooker ends, when the first pressure detection value is less than the preset pressure value, in order to ensure that the electric pressure cooker achieves the heating and pressurization effect, the pressurization time corresponding to the pressure cooking program can be further increased by 1min, 2min or 5min, which can ensure that the electric pressure cooker achieves the heating and pressurization effect of the pressure cooking program.

[0085] Exemplarily, when the pressurization time corresponding to the pressure cooking program is increased by a unit time, the number of the increased unit time may be 1 or more.

[0086] When in use, the second pressure value may be a control pressure value corresponding to a pressure cooking program and a high temperature pressure keeping program.

[0087] The beneficial effect brought about by the above-mentioned implementation method is that the heating and pressurization effect of the pressure cooking program can be detected. When the corresponding heating and pressurization effect is not achieved, the time of the pressure cooking program can be extended, which can ensure that the electric pressure cooker achieves the heating and pressurization effect of the pressure cooking program, and then ensure the stability of the cooking effect of the subsequent cooking program.

[0088] In some implementations, the above method also includes: when the electric pressure cooker enters the high-temperature pressure-keeping program, subtracting the total time of the increased unit time from the high-temperature pressure-keeping time corresponding to the high-temperature pressure-keeping program to obtain a first high-temperature pressure-keeping time, controlling the electric pressure cooker to run the first high-temperature pressure-keeping time under the high-temperature pressure-keeping program, and multiplying the pressure control value of the electric pressure cooker under the high-temperature pressure-keeping program by the ratio of the high-temperature pressure-keeping time to the first pressure-keeping time.

[0089] When the electric pressure cooker is used, after the duration of the pressure cooking program is increased by one or more unit durations using the above method, the total duration of the increased unit durations can be calculated.

[0090] In order to ensure that the total cooking time of the electric pressure cooker remains unchanged, that is, to ensure that the total cooking time of multiple cooking programs remains unchanged, when the electric pressure cooker enters the high-temperature pressure-maintaining program, the pressure-maintaining time corresponding to the high-temperature pressure-maintaining program minus the total time of the increased unit time can be obtained to obtain the first high-temperature pressure-maintaining time, and the electric pressure cooker can be controlled to run the first high-temperature pressure-maintaining time under the high-temperature pressure-maintaining program, so that the total time of multiple cooking programs remains stable, avoiding the extension of multiple cooking times. At the same time, the pressure control value of the electric pressure cooker under the high-temperature pressure-maintaining program can be multiplied by the ratio of the high-temperature pressure-maintaining time and the first high-temperature pressure-maintaining time, thereby increasing the high-temperature pressure of the electric pressure cooker under the high-temperature pressure-maintaining program and ensuring that the food can be fully cooked.

[0091] After multiplying the pressure control value of the electric pressure cooker in the high temperature pressure holding program by the ratio of the high temperature pressure holding time and the first high temperature pressure holding time, the pressure control value of the electric pressure cooker is less than the designed maximum pressure value of the electric pressure cooker, which can ensure the safety of the electric pressure cooker during use.

[0092] The beneficial effect brought about by the above-mentioned implementation method is that after increasing the duration of the high-temperature pressure holding program, the total cooking time of multiple cooking programs can be ensured to remain unchanged, and the electric pressure cooker can ensure the cooking effect of the ingredients in the high-temperature pressure holding program.
