[0002] Gas stoves are one of the most common cooking appliances in kitchens. They use natural gas, liquefied petroleum gas (LPG), or other gaseous fuels as a heat source to heat the cookware. Gas stoves typically consist of one or more burners, each with a knob to adjust the flame size, allowing users to customize the heat output for different cooking needs.

[0003] With advancements in technology and improvements in living standards, more and more gas stoves with intelligent automatic cooking functions are appearing on the market.

[0062] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0063] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of this application, which can be substituted or combined with each other. Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0064] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this application. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0065] It's important to note that gas stoves with intelligent automatic cooking functions on the market typically have preset temperature control curves and power levels for multiple cooking recipes. The temperature control curve can be understood as the real-time temperature change curve during cooking processes such as frying, stir-frying, or stewing, as the cooking time increases. The power level can be understood as the power level corresponding to different cooking times during the same process. When controlling the power level during cooking using the temperature control curve corresponding to the recipe, for example, in stewing, because stewing takes a long time and the temperature control curve tends to be stable, different power levels remain constant within a certain cooking time. If the gas pressure is too low, the overall output power of the gas stove will be low, resulting in too much leftover broth or uneven cooking of the food after automatic cooking, severely affecting the taste. Conversely, if the gas pressure is too high, the overall output power of the gas stove will be high, resulting in too little leftover broth or even premature drying after automatic cooking, also affecting the taste.

[0066] Therefore, in order to solve the technical problem of deviation in the output power of gas stoves caused by excessively high or low piped gas pressure, which in turn affects the cooking effect of recipes, this application will explain the cooking control method of gas stoves with intelligent automatic cooking in conjunction with one or more of the following embodiments.

[0067] Please refer to the following. Figure 1 , Figure 1 This paper presents an overall flowchart of a cooking control method for a gas stove according to an embodiment of the present application.

[0068] like Figure 1 As shown, the cooking control method for a gas stove may include at least the following steps:

[0069] Step 102: Determine the first heat setting according to the cooking steps in the recipe.

[0070] In this embodiment, the cooking control method for a gas stove can be applied, but is not limited to, to the control terminal of the gas stove. This control terminal can be connected to a flow regulating device and a pressure detection device installed within the gas stove. When the gas stove is automatically cooking according to a recipe, the flow regulating device's opening is controlled to correspond to a specified power level, and the pressure detection device is controlled to collect real-time gas pressure data from the gas output pipeline. The flow regulating device can be, but is not limited to, a flow regulating valve or a proportional valve well-known in the art. It can be installed on the gas output pipeline between the gas stove and the user's gas supply, and the power level of the gas stove during automatic cooking is controlled by adjusting the valve opening. Here, there is a preset correspondence between the opening degree of the flow regulating device and the firepower level of the gas stove. For example, but not limited to, when the opening degree of the flow regulating device is the first opening degree, the firepower level of the gas stove corresponds to the first level; when the opening degree of the flow regulating device is the second opening degree, the firepower level of the gas stove corresponds to the second level, and it is not limited to the number of firepower levels and the number of control opening degrees mentioned above.

[0071] The pressure detection device can be, but is not limited to, pressure sensors known in the art. It can be installed on the gas output pipeline between the flow regulating device and the burner of the gas stove. By collecting the gas pressure output to the burner in real time and feeding the collected gas pressure back to the control terminal, the control terminal can control the opening of the flow regulating device according to the gas pressure, thereby ensuring the stability of the gas stove's output power.

[0072] See also: Figure 2 The schematic diagram shown is of a gas stove provided in an embodiment of this application. Figure 2As shown, in addition to connecting with the aforementioned flow regulating device and pressure detection device, the control terminal can also connect with the main solenoid valve, temperature detection device, high-pressure ignition device, thermocouple flame detection device, control display panel, and mobile terminal installed in the gas stove to ensure the normal operation of the gas stove. The main solenoid valve (which can also be a manual stop valve) can be installed on the gas output pipeline between the flow regulating device and the user's gas supply end. When the gas stove is running, it opens the gas output pipeline between the flow regulating device and the user's gas supply end (i.e., ensures normal gas output), and it can also block the gas output pipeline between the flow regulating device and the user's gas supply end when the gas stove is off (i.e., ensures gas output stops). The temperature detection device can be installed on the burner of the gas stove to collect the burner temperature when the gas stove is running and feed the collected burner temperature back to the control terminal. The high-pressure ignition device can be, but is not limited to, a stove structure well known in the art, and after receiving instructions from the control terminal, generates... A spark ignites the gas; a thermocouple flame detection device, which can be, but is not limited to, a stove structure well-known in the art, collects a detection electrical signal indicating whether a flame is missing after the gas stove produces a flame, and feeds the detection electrical signal back to the control terminal; a control display panel, which can be, but is not limited to, located on the surface of the gas stove, can receive information such as the name of a cooking recipe or the name of a cooking step input by the user, so that the control terminal can determine the fire level and the opening degree of the corresponding flow regulating device during the automatic cooking process based on the name of the cooking recipe or the name of the cooking step; a mobile terminal can be understood as a third-party application corresponding to the gas stove, through which the user can interact with the gas stove to realize the cooking control of the gas stove or the creation of cooking recipes.

[0073] Of course, the control terminal can also be connected to other structures such as the power supply installed in the gas stove to work together with all the structures mentioned above to ensure the normal operation of the gas stove, but I will not go into details here.

[0074] It is also understandable that the control terminal installs a pressure detection device on the output pipe between the flow regulating device and the burner of the gas stove. The pressure detection device collects the gas pressure on the output pipe in real time and automatically adjusts the fire level during the cooking process according to the gas pressure, so that the output power of the gas stove is not affected, thereby ensuring the cooking effect of the dishes.

[0075] Specifically, the control terminal can, but is not limited to, receiving user-input cooking recipes via a control panel or a third-party application on a mobile terminal. Based on the recipe, it determines one or more cooking steps, extracts cooking actions and ingredients from each step, and then, combining these, determines the appropriate heat level (i.e., the first heat level) and cooking time. When determining one or more cooking steps based on the recipe, the steps can be filtered through a preset database query. This database can record multiple existing recipes and all preparation and cooking steps included in each recipe, or it can generate one or more cooking steps from an internet search; it is not limited to these methods.

[0076] It is understandable that when determining the corresponding heat level based on the cooking action and ingredients for each cooking step, it is possible, but not limited to, inputting the cooking action and ingredients for each cooking step into a preset deep learning model to obtain the corresponding heat level through model prediction. The preset deep learning model can be trained from cooking step samples with multiple known heat levels, and each cooking step sample may include at least one cooking action and at least one cooking ingredient.

[0077] It should be noted that when a user-input cooking recipe contains one cooking step, the first heat level can be understood as one or more heat levels controlled when performing that cooking step. For example, if the cooking step is stewing, the first heat level can be a heat level representing medium heat and a heat level representing low heat. When a user-input cooking recipe contains multiple cooking steps, the first heat level can be understood as one or more heat levels controlled when performing each cooking step.

[0078] In this embodiment, to ensure the normal execution of the automatic cooking process of the gas stove, before receiving the user-inputted recipe via the control display panel or a third-party application on the mobile terminal, the control terminal can also receive the user's start operation. This allows the control terminal to use a preset self-test control program to check various circuits and structures within the gas stove. For example, but not limited to, checking for abnormalities in the flow regulating device or pressure detection device, the control terminal, upon confirming that all circuits and structures within the gas stove are normal, controls the high-voltage ignition device to perform an ignition discharge operation. Here, when a successful ignition discharge operation is detected, the control terminal can further control the main solenoid valve to be in the conducting state. Simultaneously, it can control the opening degree of the flow regulating device to the opening degree corresponding to the initial ignition level. It can also control the thermocouple flame detection device to detect the flame generated by the gas stove until the detected electrical signal indicates normal flame combustion. Only then can the user-inputted recipe be received via the control display panel or a third-party application on the mobile terminal. When an ignition discharge operation fails, the control terminal can display abnormal information on the control display panel or the third-party application on the mobile terminal to remind the user to troubleshoot the gas stove promptly.

[0079] As an optional embodiment of this application, before determining the first heat level according to the cooking steps in the cooking recipe, the method further includes:

[0080] Based on at least one recipe name entered by the user, obtain at least two cooking parameters corresponding to each recipe name;

[0081] The cooking parameters corresponding to each recipe name are divided and processed to obtain all cooking parameters corresponding to the corresponding cooking steps;

[0082] A recipe database is constructed based on all recipe names and all cooking parameters corresponding to the cooking steps for each recipe name.

[0083] Specifically, to enhance the interactivity between the gas stove and the user, and to improve the efficiency of generating the first heat level based on the cooking recipe, before determining the first heat level according to the cooking steps in the recipe, the control terminal can receive multiple recipe names input by the user via a third-party application on a mobile terminal, or receive the serial number corresponding to the recipe name selected by the user via the control display panel, and obtain various cooking parameters corresponding to the gas stove during the cooking process of each recipe. Here, the various cooking parameters may include, but are not limited to, multiple standard gas pressures, multiple standard cooking temperatures, and standard cooking times that increase over time during the cooking process of each recipe, and the multiple standard gas pressures can be collected in real time by the aforementioned pressure detection device, and the multiple standard cooking temperatures can be collected in real time by the aforementioned temperature detection device.

[0084] In addition, cooking parameters may include the standard power level selected by the user as cooking time progresses for each recipe, in order to improve the efficiency of generating the first power level based on the cooking recipe, and are not limited to this.

[0085] Next, after obtaining all the cooking parameters corresponding to each recipe name, the control terminal can, but is not limited to, divide all the cooking parameters into time periods based on multiple standard gas pressures to obtain all the cooking parameters corresponding to multiple time periods. Here, the multiple standard gas pressures in all the cooking parameters corresponding to each time period are consistent, or in other words, the heat level in all the cooking parameters corresponding to different time periods is different.

[0086] Next, after dividing the cooking parameters into different time periods, the control terminal can identify the cooking actions (including ingredients) performed by the user in each time period through a camera device, and generate cooking steps based on the cooking actions (including ingredients) and the time elapsed in the corresponding time period. For example, cooking steps for a certain time period can be represented as stir-frying dish A for five minutes. Alternatively, the control terminal can display all the cooking parameters corresponding to each time period to the user through a third-party application on the mobile terminal or a control panel, so as to generate cooking steps based on the cooking step name and the time elapsed in the corresponding time period entered by the user, and is not limited to this.

[0087] Next, after determining the cooking steps corresponding to different time periods for each recipe, the control terminal can also integrate all recipe names, one or more cooking steps contained in each recipe name, and all cooking parameters corresponding to each cooking step to construct a recipe database. This allows the control terminal to query the recipe database after receiving a cooking recipe input by the user, find one or more cooking steps contained in the recipe, and all cooking parameters corresponding to each cooking step, and quickly determine the corresponding heat level (i.e., the first heat level) based on all cooking parameters corresponding to each cooking step. Of course, the recipe database in this embodiment may also include multiple existing recipes integrated manually, one or more cooking steps contained in each existing recipe, and all cooking parameters corresponding to each cooking step, and is not limited to this.

[0088] Here, when all cooking parameters corresponding to each cooking step include the standard power level, the control terminal can directly use the standard power level as the first power level for the corresponding cooking step; when all cooking parameters corresponding to each cooking step do not include the standard power level, the power level can also be calculated using the standard gas pressure as the first power level for the corresponding cooking step, but is not limited to that calculated using the standard gas pressure. For specific calculation methods, please refer to the following embodiments, which will not be elaborated here.

[0089] See also: Figure 3 The illustrated embodiment of this application provides a schematic diagram of a cooking parameter curve, as shown below. Figure 3 As shown, all cooking parameters can include multiple standard gas pressures, multiple standard cooking temperatures, and the user-selected standard power level for each recipe as cooking time increases, with the total cooking time being t3. It can be seen that by using multiple standard gas pressures or the user-selected standard power level, all cooking parameters can be divided into three time periods. The first time period is 0-t1, and correspondingly, all cooking parameters include multiple standard cooking temperatures, standard gas pressure A, and standard power level a within 0-t1, with a standard cooking time of t1. The second time period is t1-t2, and correspondingly, all cooking parameters include standard cooking temperatures, standard gas pressure B, and standard power level b within t1-t2, with a standard cooking time of t2-t1. The third time period is t2-t3, and correspondingly, all cooking parameters include standard cooking temperatures, standard gas pressure C, and standard power level c within t2-t3, with a standard cooking time of t3-t2.

[0090] As another optional embodiment of this application, the cooking parameters include standard gas pressure;

[0091] Based on the cooking steps in the recipe, determine the first heat setting, including:

[0092] In the recipe database, retrieve the standard gas pressure corresponding to the cooking steps in the recipe;

[0093] In the preset gas pressure-firepower level correspondence table, the standard firepower level corresponding to the standard gas pressure is determined, and the standard firepower level is used as the first firepower level; wherein, the preset gas pressure-firepower level correspondence table includes at least two gas pressure ranges and the standard firepower level corresponding to each gas pressure range.

[0094] Specifically, after the recipe database is built, the control terminal can query the recipe database to find one or more cooking steps included in the cooking recipe entered by the user, as well as the standard gas pressure (i.e. multiple identical standard gas pressures) corresponding to each cooking step. It can also determine the standard fire level corresponding to the standard gas pressure in the preset gas pressure-fire level correspondence table, so as to use the standard fire level as the first fire level of the corresponding cooking step.

[0095] See here. Figure 4 The diagram shown is a schematic representation of a preset gas pressure-fire level correspondence table provided in an embodiment of this application. Figure 4 As shown, the preset gas pressure-firepower level correspondence table can include five gas pressure ranges and the corresponding standard firepower level for each gas pressure range. Specifically, when the gas pressure range is 50-150Pa (the average value of the range can be 100Pa), the corresponding standard firepower level is level 1; when the gas pressure range is 150-250Pa (the average value of the range can be 200Pa), the corresponding standard firepower level is level 2; when the gas pressure range is 250-750Pa (the average value of the range can be 500Pa), the corresponding standard firepower level is level 3; when the gas pressure range is 750-1250Pa (the average value of the range can be 1000Pa), the corresponding standard firepower level is level 4; and when the gas pressure range is 1250-2000Pa (the average value of the range can be 1500Pa), the corresponding standard firepower level is level 5.

[0096] Step 104: Control the opening degree of the flow regulating device to the opening degree corresponding to the first firepower level, and obtain the first gas pressure collected by the pressure detection device.

[0097] Specifically, after determining the first heat level corresponding to the cooking step in the recipe, the control terminal can, but is not limited to, determine the standard opening degree corresponding to the first heat level based on the preset correspondence between the opening degree of the flow regulator and the heat level of the gas stove, and control the current opening degree of the flow regulator to be this standard opening degree to ensure the normal execution of the cooking step. It can be understood that when the recipe contains multiple cooking steps, the control terminal can sequentially control the current opening degree of the flow regulator to the standard opening degree corresponding to each cooking step according to the order of the multiple cooking steps, and the duration of each standard opening degree is consistent with the cooking time of the corresponding cooking step.

[0098] Furthermore, after controlling the current opening degree of the flow regulating device to the standard opening degree, the control terminal can also acquire at least two current cooking temperatures collected in real time by the aforementioned temperature detection device, so as to determine whether the currently executed cooking step is in a stable cooking temperature state through all the current cooking temperatures.

[0099] It is understandable that when the difference between any two adjacent current cooking temperatures is not greater than the preset temperature difference, it indicates that the current cooking step is in a stable cooking temperature state. The type of cooking step is, for example, but not limited to, stewing. Then, the gas pressure output to the burner, i.e., the first gas pressure, can be obtained by the pressure detection device mentioned above in real time.

[0100] In addition, to ensure the efficiency and accuracy of determining the second power level, the control terminal can also look up the standard gas range corresponding to the first power level, i.e., the first pressure range, in the preset gas pressure-power level correspondence table mentioned above. For example, but not limited to, see [reference]. Figure 4 The diagram shown is a schematic of a preset gas pressure-fire level correspondence table provided in an embodiment of this application. When the first fire level is 1, the first pressure range can be 50-150Pa.

[0101] As another optional embodiment of this application, the cooking parameters also include standard cooking temperature;

[0102] After controlling the flow regulating device to open to the level corresponding to the first power setting, the following is also included:

[0103] The system acquires at least two current cooking temperatures collected by the temperature detection device, and when the difference between any two adjacent current cooking temperatures exceeds a preset temperature difference, it determines a first temperature growth rate based on all current cooking temperatures.

[0104] The recipe database is used to find at least two standard cooking temperatures corresponding to the cooking steps, and the second temperature growth rate is determined based on all the standard cooking temperatures.

[0105] Based on the first temperature growth rate, the second temperature growth rate, and the first power level, the third power level is determined, and the opening of the flow regulating device is controlled to be the opening corresponding to the third power level.

[0106] Specifically, when the difference between any two adjacent current cooking temperatures exceeds a preset temperature difference, it indicates that the currently executed cooking step may be in a state of increasing cooking temperature. Therefore, based on all current cooking temperatures and the corresponding acquisition time (or acquisition time interval) for each current cooking temperature, the growth slope of the current cooking temperature, i.e., the first temperature growth rate, can be calculated. Here, the method for calculating the growth slope of the current cooking temperature can be a well-known technique in the art, and will not be elaborated upon further.

[0107] Next, the control terminal can query the recipe database mentioned above to find at least two different standard cooking temperatures corresponding to the currently executed cooking step. Similarly, based on all standard cooking temperatures and the acquisition time corresponding to each standard cooking temperature (or the acquisition time interval consistent with the current cooking temperature), it calculates the growth slope of the standard cooking temperature, i.e., the second temperature growth rate. Here, the method for calculating the growth slope of the standard cooking temperature can be a well-known technique in the art, and will not be elaborated upon further.

[0108] Next, the control terminal can adjust the first firepower level according to the calculated first temperature growth rate and second temperature growth rate to obtain the adjusted firepower level (i.e., the third firepower level), and can control the opening of the flow regulating device to switch to the third firepower level, so as to ensure the stability of the gas stove's output power and the overall cooking effect.

[0109] As another optional embodiment of this application, determining a third firepower level based on a first temperature growth rate, a second temperature growth rate, and a first firepower level includes:

[0110] When the first temperature growth rate is lower than the second temperature growth rate, the first firepower level is increased, and the increased first firepower level is used as the third firepower level; or

[0111] When the first temperature growth rate equals the second temperature growth rate, the first power level is used as the third power level; or

[0112] When the first temperature growth rate is higher than the second temperature growth rate, the first firepower level is downgraded, and the downgraded first firepower level is used as the third firepower level.

[0113] Specifically, when the control terminal adjusts the first firepower level based on the first and second temperature growth rates, if it detects that the first temperature growth rate is lower than the second temperature growth rate, it indicates that the current gas pressure output to the burner is too low. Therefore, the first firepower level can be increased. For example, but not limited to when the first firepower level is 3, the adjacent level 4 can be used as the increased first firepower level, i.e., the third firepower level, to ensure the stability of the gas stove's output power. When it detects that the first temperature growth rate is equal to the second temperature growth rate, it indicates that the current gas pressure output to the burner is too low. When the gas pressure of the gas stove tends to stabilize, the first power level can be directly used as the third power level. For example, but not limited to, when the first power level is 3, the third power level can be used. When the first temperature increase rate is higher than the second temperature increase rate, it indicates that the current gas pressure output to the burner is too high. The first power level can then be lowered. For example, but not limited to, when the first power level is 3, the two adjacent levels can be used as the lowered first power level, that is, the third power level, to ensure the stability of the gas stove's output power and the overall cooking effect.

[0114] Step 106: Determine the second firepower level based on the first gas pressure and the first firepower level, and control the opening of the flow regulating device to be the opening corresponding to the second firepower level.

[0115] Specifically, after acquiring the first gas pressure collected in real time by the pressure detection device, the control terminal can, but is not limited to, adjust the first power level by determining whether the first gas pressure is within the standard gas range corresponding to the first power level. For example, but not limited to taking the first power level as level 3, when the first gas pressure is lower than the standard gas range corresponding to the first power level, the first power level can be increased, that is, the adjacent level 4 can be used as the second power level; when the first gas pressure is within the standard gas range corresponding to the first power level, the first power level can be directly used as the second power level, that is, level 3 can be used as the second power level; when the first gas pressure is higher than the standard gas range corresponding to the first power level, the first power level can be decreased, that is, the adjacent level 2 can be used as the second power level.

[0116] Here, the standard gas range (i.e., the first pressure range) corresponding to the first power level can be obtained by referring to the preset gas pressure-power level correspondence table mentioned above, for example, but not limited to, the table provided. Figure 4 The diagram shown is a schematic of a preset gas pressure-fire level correspondence table provided in an embodiment of this application. When the first fire level is 3, the first pressure range can be 250-750Pa.

[0117] Furthermore, after determining the second power level, the control terminal can, but is not limited to, determine the standard opening degree corresponding to the second power level based on the preset correspondence between the opening degree of the flow regulating device and the power level of the gas stove, and control the current opening degree of the flow regulating device to be the standard opening degree, so as to ensure the stability of the output power of the gas stove and the overall cooking effect.

[0118] See also: Figure 5 The illustrated diagram shows another cooking parameter curve provided in the embodiment of this application, such as... Figure 5 As shown, all cooking parameters can include multiple real-time gas pressures, multiple real-time cooking temperatures, and the user-selected real-time heat level for each recipe during the cooking process, with the total cooking time being t6. Combined with... Figure 3 as well as Figure 5 It can be seen that, Figure 5 During the time period t1-t3 shown, the user-selected heat level was increased, and the corresponding real-time gas pressure also increased with cooking time; Figure 5 During the time period t3-t6 shown, the user's selected heat level was adjusted up and down, and the corresponding real-time gas pressure first increased and then decreased with the cooking time.

[0119] As another optional embodiment of this application, the cooking parameters also include standard cooking time;

[0120] After controlling the flow regulating device to open to the level corresponding to the second power setting, the following is also included:

[0121] The second gas pressure collected by the pressure detection device is obtained, and the third gas pressure is determined based on the first pressure range;

[0122] When the second gas pressure is lower than the third gas pressure, the standard cooking time corresponding to the cooking step is retrieved from the recipe database, and the target cooking time is calculated based on the standard cooking time, the second gas pressure, and the third gas pressure; or

[0123] When the second gas pressure is lower than the third gas pressure, the difference between the third gas pressure and the second gas pressure is calculated, and the corresponding supplementary time is retrieved from the preset pressure difference-supplementary time correspondence table; wherein, the preset pressure difference-supplementary time correspondence table includes at least two pressure difference intervals and the standard supplementary time corresponding to each pressure difference interval;

[0124] The standard cooking time for each cooking step is retrieved from the recipe database, and the target cooking time is determined based on the standard supplementary time and the standard cooking time.

[0125] When the gas supply to the user is at its peak and the output gas pressure is extremely low, the overall cooking time can be increased to further ensure the stability of the gas stove's output power and the overall cooking effect.

[0126] Specifically, after controlling the opening of the flow regulating device to the opening corresponding to the second firepower level, the control terminal can also obtain the gas pressure output to the burner collected by the pressure detection device, which is the second gas pressure. At the same time, it can also obtain the average pressure of the first pressure range (i.e., the first pressure range) corresponding to the first firepower level by using the average calculation method, which is the third gas pressure.

[0127] Next, when the second gas pressure is detected to be lower than the third gas pressure, it indicates that the user's gas supply is currently experiencing peak gas consumption. The standard cooking time corresponding to the currently executed cooking step can then be retrieved from the recipe database. The standard cooking time, the second gas pressure, and the third gas pressure are then substituted into a preset time formula to calculate the target cooking time. Here, the preset time formula may include, but is not limited to, the following:

[0128] T = T0 + ((P0 - P1) / P0) * T0

[0129] In the above formula, T can be the target cooking time, T0 can be the standard cooking time, P0 can be the third gas pressure, and P1 can be the second gas pressure.

[0130] For example, taking the current cooking step as stewing, with corresponding cooking parameters including a heat level of 4 and a cooking time of 30 minutes, when the first gas pressure is 500 Pa, the second heat level can be determined to be 5, and the detected second gas pressure is 800 Pa. Referring to the preset gas pressure-heat level correspondence table mentioned above, it can be seen that the standard pressure range when the heat level is 4 is 750-1250, and the corresponding average pressure is 1000 (i.e., the third gas pressure). Since the second gas pressure is lower than the third gas pressure at this time, the actual cooking time of the current cooking step can be calculated to be 36 minutes using the preset time formula mentioned above.

[0131] When the second gas pressure is equal to the third gas pressure, it indicates that the user's gas supply is not currently in peak gas consumption. At this time, the opening of the flow regulating device can be kept at the opening corresponding to the second power level. When the second gas pressure is greater than the third gas pressure, it also indicates that the user's gas supply is not currently in peak gas consumption. At this time, the output power of the gas stove can be ensured by adjusting the second power level.

[0132] Understandably, when the second gas pressure is detected to be lower than the third gas pressure, it indicates that the user's gas supply is currently experiencing peak gas consumption. It is possible, but not limited to, calculating the difference between the third and second gas pressures and retrieving the corresponding supplementary time from a preset pressure difference-supplementary time table. (See here for more information.) Figure 6 The diagram shown is a schematic representation of a preset pressure difference-supplement time correspondence table provided in an embodiment of this application. Figure 6 As shown, the preset pressure difference-replenishment time correspondence table can include four pressure difference ranges and the standard replenishment time corresponding to each pressure difference range. Specifically, when the pressure difference range is less than or equal to 100 Pa, the corresponding standard replenishment time is 3 minutes; when the pressure difference range is 100-200 Pa, the corresponding standard replenishment time is 5 minutes; when the pressure difference range is 200-500 Pa, the corresponding standard replenishment time is 8 minutes; and when the pressure difference range is greater than 500 Pa, the corresponding standard replenishment time is 10 minutes.

[0133] Next, after retrieving the standard supplementary time, the control terminal can also query the recipe database for the standard cooking time corresponding to the currently executed cooking step, and sum the standard cooking time and the standard supplementary time to obtain the target cooking time. For example, taking the currently executed cooking step as stewing, with corresponding cooking parameters including a heat level of 4 and a cooking time of 30 minutes, when the first gas pressure is 500Pa, the second heat level can be determined to be 5, and the detected second gas pressure is 800Pa. Referring to the preset gas pressure-heat level correspondence table mentioned above, it can be seen that the standard pressure range when the heat level is 4 is 750-1250, and the corresponding average pressure is 1000 (i.e., the third gas pressure). Since the difference between the third gas pressure and the second gas pressure is 200Pa, the standard supplementary time can be found to be 5 minutes through the preset pressure difference-supplementary time correspondence table, thus concluding that the actual cooking time for the currently executed cooking step should be 35 minutes.

[0134] In the embodiments of this application, the actual cooking time of the currently executed cooking step can be calculated in the two ways described above, but is not limited to them. When the two actual cooking times are inconsistent, the final cooking time of the currently executed cooking step can be obtained by averaging, and is not limited to this.

[0135] As another optional embodiment of this application, after controlling the opening degree of the flow regulating device to the opening degree corresponding to the second firepower level, it further includes:

[0136] The table corresponds to a first gas pressure and a gas consumption. The table is used to find the second pressure range, the first gas consumption, the third pressure range, and the second gas consumption corresponding to the third pressure range. The table includes at least two gas pressure ranges and the standard gas consumption for each range. The second and third pressure ranges are adjacent. The first gas pressure is within the second pressure range and is higher than the third pressure range.

[0137] The fourth gas pressure is determined based on the second pressure range, and the fifth gas pressure is determined based on the third pressure range. The cooking gas consumption is calculated based on the first gas pressure, the fourth gas pressure, the fifth gas pressure, the first gas consumption, the second gas consumption, and the standard cooking time.

[0138] To make it easier for users to view gas consumption during cooking, the system can also combine the initial gas pressure with a preset gas pressure-gas consumption table to calculate the gas consumption during cooking and provide real-time feedback on a third-party application on the mobile device, giving users a more intuitive experience.

[0139] Specifically, after controlling the opening of the flow regulating device to the opening corresponding to the second firepower level, the control terminal can also look up the second pressure range corresponding to the first gas pressure, the first gas consumption corresponding to the second pressure range, the third pressure range, and the second gas consumption corresponding to the third pressure range in the preset gas pressure-gas consumption correspondence table. The second pressure range can be understood as a standard gas range that includes the first gas pressure, and the third pressure range can be understood as a standard gas range adjacent to the second pressure range, and the third pressure range is lower than the first gas consumption.

[0140] See here. Figure 7 The diagram shown is a schematic representation of a preset gas pressure-gas consumption correspondence table provided in an embodiment of this application. Figure 7 As shown, the preset gas pressure-gas consumption correspondence table may include five gas pressure ranges and the standard gas consumption corresponding to each gas pressure range, and may also include the standard firepower level corresponding to each gas range.

[0141] Next, the average pressure of the second pressure range, i.e., the fourth gas pressure, and the average pressure of the third pressure range, i.e., the fifth gas pressure, can be obtained using an average calculation method. These fourth and fifth gas pressures, along with the aforementioned first gas pressure, first gas consumption, second gas consumption, and standard cooking time, are then substituted into a preset gas consumption formula to calculate the gas consumption corresponding to the currently executed cooking step. Here, the preset gas consumption formula can be, but is not limited to, as follows:

[0142] Q0=(P-P5)*(P4-P5) / (Q2-Q1)+Q1

[0143] Q = Q0 * T0

[0144] In the above formula, Q can be the amount of gas used for cooking corresponding to the current cooking step, T0 can be the standard cooking time, P can be the first gas pressure, P5 can be the fifth gas pressure, P4 can be the fourth gas pressure, Q2 can be the first gas consumption, and Q1 can be the second gas consumption.

[0145] Next, after obtaining the amount of cooking gas corresponding to the currently executed cooking step, the control terminal may, but is not limited to, temporarily store the amount of cooking gas corresponding to the currently executed cooking step, and after calculating the total amount of cooking gas corresponding to all cooking steps of the cooking recipe, feed the total amount of cooking gas back to the third-party application of the mobile terminal, or feed the sum of all cooking gas within the preset time period back to the third-party application of the mobile terminal according to the preset time period, and is not limited to this.

[0146] In addition, after the cooking process is completed, the control terminal can, but is not limited to, acquire the gas pressure output to the burner collected by the pressure detection device again, so as to determine whether the main solenoid valve is completely closed based on the gas pressure, thereby ensuring the safety of the gas stove.

[0147] Of course, in this embodiment of the application, after controlling the opening of the flow regulating device to the opening corresponding to the second firepower level, the control terminal can again acquire the gas pressure output to the burner collected by the pressure detection device, and adjust the range hood fan speed of the gas stove according to the magnitude of the gas pressure. For example, but not limited to, when the gas pressure is lower than the standard gas range corresponding to the first firepower level (or the average pressure of the standard gas range), the range hood fan speed of the gas stove can be increased; when the gas pressure is higher than the standard gas range corresponding to the first firepower level (or the average pressure of the standard gas range), the range hood fan speed of the gas stove can be decreased, and it is not limited to this.
