[0002] Electric pressure cookers have the function of cooking food quickly and are an indispensable cooking tool in modern kitchens.

[0003] Electric pressure cookers can cook food quickly through high temperature and high pressure. There is pressure in the pot during the cooking process, so there is a degassing stage before opening the lid. During the degassing stage, the temperature in the pot drops. When the domestic temperature reaches the boiling point, it will boil and overflow will easily occur. In order to avoid overflow, the exhaust method used in various complex situations has low exhaust efficiency and a long total exhaust time.

[0004] In order to avoid overflowing of the cooking utensils during the exhaust stage in the related art, resulting in long exhaust time and low exhaust efficiency, no effective solution has been proposed yet. Summary of the invention

[0005] The present application provides an exhaust control method, a cooking appliance, a computer program product and an electronic device to solve the problem in the related art that the exhaust time is long and the exhaust efficiency is low in order to avoid overflowing of the cooking appliance during the exhaust stage.

[0006] According to one aspect of the present application, an exhaust control method is provided. The method includes: when the cooking appliance enters the exhaust phase, periodically determining the amount of gas generated by the food inside the cooking appliance; periodically adjusting the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food, and controlling the exhaust of the cooking appliance according to the exhaust hole after the adjusted area until the exhaust phase ends, wherein the size of the adjusted exhaust hole area is inversely correlated with the amount of gas. By periodically adjusting the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food during the exhaust phase, and exhausting according to the exhaust hole after the adjusted area, the effect of shortening the exhaust time and improving the exhaust efficiency is achieved while avoiding the overflow phenomenon.

[0007] Optionally, periodically adjusting the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food includes: when the amount of gas is less than or equal to a first threshold and greater than a second threshold, adjusting the area of ​​the exhaust hole to a first area, wherein the first threshold is greater than the second threshold; when the amount of gas is less than the second threshold and greater than or equal to a third threshold, adjusting the area of ​​the exhaust hole to a second area, wherein the second threshold is greater than the third threshold and the first area is less than the second area; when the amount of gas is less than the third threshold and greater than or equal to zero, adjusting the area of ​​the exhaust hole to a third area, wherein the second area is less than the third area. By comparing the total amount of gas generated at each moment of the exhaust stage with the exhaust area threshold, the opening area of ​​the exhaust hole is adaptively and dynamically adjusted, so that various cooking situations can be exhausted efficiently and the exhaust time is shortened.

[0008] Optionally, the exhaust time of the cooking appliance under the exhaust hole of the first area is the first exhaust time, the exhaust time of the cooking appliance under the exhaust hole of the second area is the second exhaust time, and the exhaust time of the cooking appliance under the exhaust hole of the third area is the third exhaust time, wherein the first exhaust time is less than or equal to the second exhaust time, and the second exhaust time is less than or equal to the third exhaust time. When the opening area of ​​the exhaust hole is small, a smaller exhaust time is set, when the opening area of ​​the exhaust hole is moderate, a moderate exhaust time is set, and when the opening area of ​​the exhaust hole is large, a larger exhaust time is set, so as to achieve the effect of improving the exhaust efficiency and shortening the total exhaust time while preventing overflow.

[0009] Optionally, controlling the cooking appliance to exhaust gas according to the adjusted exhaust hole until the exhaust stage ends includes: controlling the cooking appliance to exhaust gas according to the adjusted exhaust hole until the gas volume is zero; when the gas volume is zero, adjusting the size of the exhaust hole to the maximum, and outputting a cooking completion signal after a preset time interval. This ensures that all gas in the cooking appliance is exhausted, and improves the safety of opening the lid.

[0010] Optionally, periodically determining the amount of gas generated by food inside the cooking appliance includes: periodically detecting the value of an influencing parameter that affects the amount of gas generated by the food; determining the gas amount parameter value according to the value of the influencing parameter, and converting the gas amount parameter value into the gas amount according to a conversion factor, wherein the conversion factor is a ratio of a unit gas amount to a unit gas amount parameter value. The value of the influencing parameter that affects the amount of gas generated by the food is converted into a gas amount parameter value that characterizes the degree of influence on the gas amount, and then the gas amount parameter value is converted into the gas amount according to the conversion factor, thereby achieving the effect of efficiently determining the amount of gas generated by the food during the exhaust stage.

[0011] Optionally, the influencing parameters include at least one of the following: food material parameters, food quantity parameters, and temperature difference between the inside and outside of the cooking vessel, wherein the food material parameters are determined by the degree to which the food is easy to overflow during cooking. Determining at least one of the food material parameters, food quantity parameters, and temperature difference between the inside and outside of the cooking vessel as an influencing parameter affecting the amount of gas generated by the food lays a data foundation for determining the amount of gas generated by the food during the exhaust stage.

[0012] Optionally, determining the gas quantity parameter value according to the value of the influencing parameter includes: when there is one influencing parameter, determining the value of the influencing parameter as the gas quantity parameter value; when there are at least two influencing parameters, calculating the product of the values ​​of at least two influencing parameters to obtain the gas quantity parameter value. In order to efficiently determine the gas quantity parameter value, the value of one influencing parameter is determined as the gas quantity parameter value. In order to accurately determine the gas quantity parameter value, the product of the values ​​of all influencing parameters can be determined as the gas quantity parameter value. In order to balance efficiency and accuracy, the product of the values ​​of any several influencing parameters can also be determined as the gas quantity parameter value, thereby achieving the purpose of flexibly determining the gas quantity parameter value according to demand.

[0013] Optionally, the food material parameters are determined in the following manner: obtaining the cooking function selected by the user, and determining the food material parameters from a preset comparison table according to the cooking function, wherein the preset comparison table records a plurality of preset cooking functions and the food material parameters corresponding to each preset cooking function. The degree to which different foods are prone to overflowing is quantified as different food material parameters. Since the cooking function is related to the type of food, a preset comparison table of cooking functions and food material parameters is set. Once the cooking function selected by the user is obtained, the food material parameters can be obtained efficiently and accurately through the preset comparison table. The food material parameters are determined as influencing parameters that affect the amount of gas generated by the food, which lays a data foundation for determining the amount of gas generated by the food during the exhaust stage.

[0014] According to another aspect of the present application, a cooking appliance is provided, wherein a controller of the cooking appliance is used to execute an exhaust control method to exhaust air during an exhaust phase of the cooking appliance.

[0015] According to another aspect of the present application, a computer program product is provided, including a non-volatile computer-readable storage medium, wherein the non-volatile computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, an exhaust control method is implemented.

[0016] According to another aspect of the present application, an electronic device is also provided, comprising a processor and a memory; the memory stores computer-readable instructions, and the processor is used to execute the computer-readable instructions, wherein an exhaust control method is executed when the computer-readable instructions are executed.

By periodically adjusting the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food in the exhaust stage in reverse, and exhausting according to the exhaust hole after the adjusted area, the effect of shortening the exhaust time and improving the exhaust efficiency while avoiding overflowing of the pot is achieved.

[0028] It should be noted that the relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0029] It should be noted that the collected information used in this application is information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant regions, take necessary confidentiality measures, do not violate public order and good customs, and provide corresponding operation entrances for users to choose to authorize or refuse to use it.

[0030] According to an embodiment of the present application, an exhaust control method is provided.

[0031] Figure 1 is a flow chart of an exhaust control method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0032] Step S102: when the cooking appliance enters the exhaust phase, periodically determine the amount of gas generated by the food inside the cooking appliance.

[0033] Among them, the cooking appliance can be a pressure cooking appliance, for example, the pressure cooking appliance can be an electric pressure cooker. After putting food into the electric pressure cooker, selecting the corresponding cooking function and starting cooking, the food can be cooked according to the cooking program corresponding to the cooking function. Since water vapor is generated during the cooking process, there is a pressure difference inside and outside the pot. In order to open the lid safely, an exhaust stage is provided at the end of the cooking program.

[0034] The food inside the cooking utensil may be rice, quick dishes (e.g., salt-baked dishes), soups, porridge, etc. It should be noted that, depending on the food inside the cooking utensil, the amount of gas generated in different time periods during the exhaust phase is also different. Therefore, the embodiment of the present application periodically determines the amount of gas generated by the food inside the cooking utensil to flexibly control the exhaust. During the exhaust phase, the amount of gas generated by the food inside the cooking utensil may be determined in real time at intervals of time t. Since the temperature inside the cooking utensil does not change much during the exhaust phase, the value range of t may be a smaller range, for example, 0.1-1s.

[0035] Step S104, periodically adjusting the size of the exhaust hole of the cooking appliance according to the amount of gas generated by the food, and controlling the exhaust of the cooking appliance according to the exhaust hole after the adjustment until the exhaust phase ends, wherein the size of the exhaust hole after the adjustment is inversely correlated with the amount of gas.

[0036] This embodiment periodically determines the amount of gas generated by the food inside the cooking utensil, and adjusts the size of the area of ​​the exhaust hole of the cooking utensil according to the amount of gas generated by the food. In this embodiment, adjusting the size of the area of ​​the exhaust hole of the cooking utensil refers to adjusting the size of the open area of ​​all the exhaust holes. In the case of a large amount of gas generated by the food, in order to avoid overflowing the pot due to high-speed exhaust, this embodiment adjusts the open area of ​​the exhaust hole to a smaller area, and controls the exhaust of the cooking utensil so that the gas generated by the food in the cooking utensil is gradually discharged. Since the cooking utensil is not heated during the exhaust phase, the amount of gas generated by the food gradually decreases during the exhaust process. In the case of a small amount of gas generated by the food, it is not easy to overflow, and the open area of ​​the exhaust hole is adjusted to a larger area, and the exhaust of the cooking utensil is controlled so that the gas generated by the food in the cooking utensil is quickly discharged.

[0037] For example, the cooking utensil in this embodiment is provided with two or more exhaust channels on the pot body, each exhaust channel has different exhaust holes, the sizes of the different exhaust holes can be the same or different, and each exhaust hole can be controlled separately. This embodiment does not limit the number of exhaust channels and the structure of exhaust holes of the cooking utensil. Figure 2 Schematic diagram of an exhaust device for a cooking appliance according to an embodiment of the present application Figure 1 ,like Figure 2As shown, the main body of the cooking device is provided with two exhaust holes, a small exhaust hole and a large exhaust hole, and the two exhaust holes are arranged in parallel. Figure 3 Schematic diagram of an exhaust device for a cooking appliance according to an embodiment of the present application Figure 2 ,like Figure 3 As shown, the main body of the cooking utensil is provided with two exhaust holes, a small exhaust hole and a large exhaust hole, and the two exhaust holes are arranged opposite to each other. When two or more exhaust holes are provided on the pot body of the cooking utensil, the opening area of ​​the exhaust holes can be adjusted by opening or closing exhaust holes of different sizes.

[0038] It should be noted that in the related art, the exhaust time is mainly adjusted by the temperature or pressure in the pot. Compared with the present embodiment, a longer time is required to exhaust the same amount of gas, otherwise it is easy to overflow. In the present embodiment, the size of the exhaust hole is adjusted by the amount of gas generated by the food. In the case of no overflow, more gas can be discharged in a short time, and the exhaust efficiency is higher.

[0039] The exhaust control method provided in the embodiment of the present application periodically determines the amount of gas generated by the food inside the cooking utensil when the cooking utensil enters the exhaust stage; periodically adjusts the size of the exhaust hole area of ​​the cooking utensil according to the amount of gas generated by the food, and controls the exhaust of the cooking utensil according to the exhaust hole after the adjusted area until the exhaust stage ends, wherein the size of the adjusted exhaust hole area is inversely correlated with the amount of gas, thereby solving the problem of long exhaust time and low exhaust efficiency in order to avoid overflowing of the pot in the related art. By periodically adjusting the size of the exhaust hole area of ​​the cooking utensil in reverse according to the amount of gas generated by the food during the exhaust stage, and exhausting according to the exhaust hole after the adjusted area, the effect of shortening the exhaust time and improving the exhaust efficiency while avoiding overflowing of the pot is achieved.

[0040] The amount of gas generated by food can be determined by an influencing parameter that affects the size of the gas generated by the food. Optionally, in the exhaust control method provided in the embodiment of the present application, periodically determining the amount of gas generated by food inside the cooking utensil includes: periodically detecting the value of the influencing parameter that affects the size of the gas generated by the food; determining the gas amount parameter value based on the value of the influencing parameter, and converting the gas amount parameter value into gas amount based on a conversion factor, wherein the conversion factor is the ratio of the unit gas amount to the unit gas amount parameter value.

[0041] Specifically, the influencing parameters that affect the amount of gas generated by food are first determined, and the influencing parameters may be one or more, and the values ​​of the influencing parameters are detected to obtain the values ​​of one or more influencing parameters, and the values ​​of the influencing parameters are converted into gas amount parameter values. Since the gas amount parameter value represents the degree of influence on the gas amount, not the actual gas amount, the gas amount parameter value is converted into gas amount through a conversion factor. It should be noted that the conversion factor is the ratio of the unit gas amount to the unit gas amount parameter value. When the influencing parameters are different, the unit gas amount parameter values ​​are different, and the conversion factors are also different.

[0042] Through this embodiment, the value of the influencing parameter that affects the amount of gas generated by food is converted into a gas quantity parameter value that characterizes the degree of influence on the gas quantity, and then the gas quantity parameter value is converted into gas quantity based on the conversion factor, thereby achieving the effect of efficiently determining the amount of gas generated by food during the exhaust stage.

[0043] There may be multiple influencing parameters that affect the amount of gas generated by food. Optionally, in the exhaust control method provided in the embodiment of the present application, the influencing parameters include at least one of the following: food ingredient parameters, food portion parameters, and the temperature difference between the inside and outside of the cooking utensil, wherein the ingredient parameters are determined by the degree to which the food is prone to overflow during cooking.

[0044] Among them, the ingredient parameters of food represent the degree to which the food is easy to overflow during cooking, and are related to the water content of the food. For example, the water content of rice is very low in the exhaust stage, and the degree of easy overflow is low, so a smaller ingredient parameter can be set; the water content of quick dishes is very low in the exhaust stage, and the degree of easy overflow is low, so a smaller ingredient parameter can be set; the water content of soups is relatively high in the exhaust stage, and the degree of easy overflow is relatively high, so a larger ingredient parameter can be set; the water content of porridge is relatively high in the exhaust stage, compared with soups that only produce oily steam, porridge will produce viscous liquid that slowly accumulates and becomes higher, which is more likely to overflow, so a larger ingredient parameter can be set.

[0045] Among them, the portion parameter of the food can be the portion size of the food. For example, when the food portion is a small amount, a smaller portion parameter can be set; when the food portion is a medium amount, a middle portion parameter can be set; when the food portion is a large amount, a larger portion parameter can be set; when the food portion is a full pot, a maximum portion parameter can be set.

[0046] The temperature difference between the inside and outside of the cooking appliance can be determined by measuring the top steam temperature of the cooking appliance by a top temperature sensor, calculating the difference between the top steam temperature and the boiling point temperature, and obtaining the temperature difference between the inside and outside of the cooking appliance. In addition, when determining the gas volume parameter value, the temperature difference between the inside and outside of the cooking appliance as an influencing parameter can also be replaced by the pressure difference between the inside and outside of the cooking appliance.

[0047] Through this embodiment, at least one of the food ingredient parameters, food portion parameters, and the temperature difference between the inside and outside of the cooking utensil is determined as an influencing parameter affecting the amount of gas generated by the food, laying a data foundation for determining the amount of gas generated by the food during the exhaust stage.

[0048] The gas quantity parameter value can be flexibly determined by different influencing parameters. Optionally, in the exhaust control method provided in the embodiment of the present application, determining the gas quantity parameter value according to the value of the influencing parameter includes: when the influencing parameter is one, determining the value of the influencing parameter as the gas quantity parameter value; when the influencing parameter includes at least two, calculating the product of the values ​​of at least two influencing parameters to obtain the gas quantity parameter value.

[0049] It should be noted that in order to efficiently determine the gas quantity parameter value, the value of an influencing parameter can be determined as the gas quantity parameter value. In order to accurately determine the gas quantity parameter value, the product of the values ​​of all influencing parameters can be determined as the gas quantity parameter value. In order to take into account both efficiency and accuracy, the product of the values ​​of any several influencing parameters can also be determined as the gas quantity parameter value, thereby achieving the purpose of flexibly determining the gas quantity parameter value according to demand.

[0050] In an optional embodiment, when the influencing parameters include food ingredient parameters, food portion parameters and the temperature difference between the inside and outside of the cooking appliance (or the pressure difference between the inside and outside of the cooking appliance), the gas quantity parameter value Dt can be calculated by the following formula: Dt = A*B*(TF)*m, wherein A is the value of the ingredient parameter, B is the value of the portion parameter, T is the temperature of the steam at the top of the cooking appliance, F is the boiling point, and m is the conversion factor, specifically the ratio of the unit gas quantity and the unit gas quantity parameter value. In this embodiment, the unit gas quantity parameter value can be the product of the unit ingredient parameter value a, the unit portion parameter value b and the unit temperature.

[0051] The cooking function is related to the type of food, and the type of food determines the degree to which the food is likely to overflow. Optionally, in the exhaust control method provided in the embodiment of the present application, the ingredient parameters of the food are determined in the following manner: obtaining the cooking function selected by the user, and determining the ingredient parameters from a preset comparison table according to the cooking function, wherein the preset comparison table records multiple preset cooking functions and the ingredient parameters corresponding to each preset cooking function.

[0052] Table 1 is a preset comparison table of the present embodiment, that is, a preset food parameter table. When a cooking function selected by a user is detected, the preset food parameter table can be read to obtain food parameter A corresponding to the cooking function. Food parameter A represents the degree to which food is prone to overflow.

[0053] Table 1

[0054]

[0055] As shown in Table 1, the minimum unit of the degree to which food is prone to overflow can be a, where a can range from 0.1 to 10. Rice is prone to overflowing at a very low degree during the exhaust stage, and the ingredient parameter can be set to a. Quick dishes are prone to overflowing at a very low degree during the exhaust stage, and the ingredient parameter can be set to a. Soups are prone to overflowing at a relatively high degree during the exhaust stage, and the ingredient parameter can be set to 50a. Soups are more prone to overflowing at an even higher degree during the exhaust stage, and the ingredient parameter can be set to 100a.

[0056] Through this embodiment, the degree to which different foods are prone to overflow is quantified into different food parameters. Since the cooking function is related to the type of food, a preset comparison table of cooking functions and food parameters is set. Once the cooking function selected by the user is obtained, the food parameters can be efficiently and accurately obtained through the preset comparison table. The food parameters are determined as influencing parameters that affect the amount of gas generated by the food, which lays a data foundation for determining the amount of gas generated by the food during the exhaust stage.

[0057] The portion of food can be the volume of food or the weight of food. Optionally, in the exhaust control method provided in the embodiment of the present application, the portion parameter of food is obtained in the following manner: after the cooking function of the cooking appliance is started, it enters the heating stage, and the portion size of the food is obtained through the portion judgment program in the heating stage. For example, the portion size of the food can be determined by measuring how much power the food consumes from the beginning of heating to boiling. For another example, the portion size of the food can be determined by measuring how much power the food consumes within a fixed temperature range (for example, 25°C-90°C) in the heating stage. For another example, the portion size of the food can be determined by the temperature rise of the food consuming a fixed power in the heating stage. After obtaining the portion size of the food, the preset portion parameter table can be read to obtain the portion parameter B. Table 2 is the preset portion parameter table of this embodiment.

[0058] Table 2

[0059]

[0060] As shown in Table 2, the minimum unit of food portion size can be b, where the range of b can be 0.1-10, and the portion parameter can be set to b when the food portion is a small amount, 3b when the food portion is a medium amount, 9b when the food portion is a large amount, and 10b when the food portion is a full pot.

[0061] In order to shorten the exhaust time while avoiding overflow, optionally, in the exhaust control method provided in the embodiment of the present application, periodically adjusting the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food includes: when the gas amount is less than or equal to a first threshold and greater than a second threshold, adjusting the exhaust hole area to a first area, wherein the first threshold is greater than the second threshold; when the gas amount is less than the second threshold and greater than or equal to a third threshold, adjusting the exhaust hole area to a second area, wherein the second threshold is greater than the third threshold, and the first area is smaller than the second area; when the gas amount is less than the third threshold and greater than or equal to zero, adjusting the exhaust hole area to a third area, wherein the second area is smaller than the third area.

[0062] In an optional embodiment, the total gas volume Dt at each moment of the exhaust phase is A*B*(TF)*m, wherein A is the value of the food parameter, B is the value of the component parameter, T is the temperature of the steam on the top of the cooking utensil, F is the boiling point, and m is a conversion factor, specifically the ratio of the unit gas volume to the unit gas volume parameter value, the unit gas volume parameter value is the product of the unit food parameter value a, the unit component parameter value b and the unit temperature, a can range from 0.1-10, b can range from 0.1-10, and m can range from 0.1-10. The first threshold value K_s ranges from 22500-27500abm, the second threshold value K_b ranges from 2250-2750abm, and the third threshold value K_sb ranges from 225-275abm.

[0063] In an optional embodiment, the total gas volume at each moment of the exhaust stage Dt = A*(TF)*m, wherein A is the value of the food parameter, T is the temperature of the steam on the top of the cooking utensil, F is the boiling point, and m is a conversion factor, specifically the ratio of the unit gas volume to the unit gas volume parameter value, the unit gas volume parameter value is the product of the unit food parameter value a and the unit temperature, a can range from 0.1-10, and m can range from 0.1-10. The first threshold value K_s ranges from 11700-14300 abm, the second threshold value K_b ranges from 405-495 abm, and the third threshold value K_sb ranges from 225-275 abm.

[0064] In an alternative embodiment, the total gas volume Dt at each moment during the exhaust stage is Dt = B * (T - F) * m, where B is the value of the component parameter, T is the temperature of the steam at the top of the cooking appliance, F is the boiling point, and m is the conversion factor, specifically the ratio of the unit gas volume to the value of the unit gas volume parameter. The value of the unit gas volume parameter is the product of the value b of the unit component parameter and the unit temperature. The range of b can be from 0.1 to 10, and the range of m can be from 0.1 to 10. The range of the first threshold K_s is 117 - 143 abm, the range of the second threshold K_b is 28.8 - 35.2 abm, and the range of the third threshold K_sb is 13.5 - 16.5 abm.

[0065] It should be noted that the three thresholds K_s, K_b, and K_sb are all exhaust area thresholds. Based on the magnitude relationship between the total exhaust volume Dt at each moment during the exhaust stage and each exhaust area threshold, the opening area of the exhaust holes is adaptively and dynamically adjusted. If the cooking appliance is provided with a large hole and a small hole for two exhaust holes, the opening area of the exhaust holes can be adjusted by opening or closing the exhaust holes of different sizes: When K_b ≤ Dt < K_s, only the small hole is opened for exhaust during exhaust, that is, the amount of gas generated is large. To avoid overflow, the opening area of the exhaust hole is adjusted to a smaller area. When K_sb ≤ Dt < K_b, only the large hole is opened for exhaust during exhaust, that is, the amount of gas generated is moderate, indicating that the food is not likely to overflow, or the food portion is small, or the temperature or pressure is low, and less gas needs to be exhausted. The opening area of the exhaust hole is adjusted to a moderate area, and a continuous discharge of more gas will not cause overflow. When 0 < Dt < K_sb, both the large and small holes are opened for exhaust during exhaust, that is, the amount of gas generated is small, and there is basically no risk of overflow. The opening area of the exhaust hole is adjusted to a larger area, which can further improve the exhaust efficiency.

[0066] In an alternative embodiment: The influencing parameters affecting the amount of gas generated by the food include the food ingredient parameter, the food portion parameter, and the temperature difference between the inside and outside of the cooking appliance. The total gas volume Dt at each moment during the exhaust stage is Dt = A * B * (T - F) * m, the first threshold K_s = 25000 abm, the second threshold K_b = 2500 abm, the third threshold K_sb = 250 abm, F = 100 °C, and there are two exhaust holes, a large exhaust hole and a small exhaust hole, provided on the pot body of the cooking appliance. The opening area of the exhaust holes is adjusted by opening or closing the exhaust holes of different sizes.

[0067] Exemplarily, when cooking a large amount of rice at a working pressure of 50 kPa, after the cooking starts, the preset ingredient parameter table is read to obtain the ingredient parameter A = a. During the heating-up stage, the portion parameter B = 9b is obtained through the portion judgment program. When the internal temperature T of the cooking appliance is detected to be 110 °C at the start of the exhaust stage, the total exhaust volume Dt = a * 9b * (110 - 100) * m = 90abm at this time. Since 0 < Dt < K_sb, that is, 0 < T < (K_sb / (A * B * m) + F), during the entire exhaust stage, both the large and small holes are opened for exhaust while exhausting.

[0068] Exemplarily, when cooking a medium amount of soup at a working pressure of 70 kPa, after the cooking starts, the preset ingredient parameter table is read to obtain the ingredient parameter A = 50a. During the heating-up stage, the portion parameter B = 3b is obtained through the portion judgment program. When the internal temperature T of the cooking appliance is detected to be 114 °C at the start of the exhaust stage, the total exhaust volume Dt = 50a * 3b * (114 - 100) * m = 2100abm at this time. Since the total exhaust volume becomes smaller and smaller as the exhaust time progresses, when K_sb ≤ Dt < K_b, that is, (K_sb / (A * B * m) + F) ≤ T < (K_s / (A * B * m) + F), during the period when the internal temperature of the cooking appliance is 102 °C ≤ T < 114 °C, only the large hole is opened for exhaust while exhausting; when 0 < Dt < K_sb, that is, 0 < T < (K_sb / (A * B * m) + F), during the period when the internal temperature of the cooking appliance is 101 °C ≤ T < 102 °C, both the large and small holes are opened for exhaust while exhausting; when Dt = 0, when the internal temperature T of the cooking appliance is detected to be F, both the large and small holes are opened for exhaust for 5 seconds and then the exhaust stage ends.

[0069] Exemplarily, when cooking a large amount of congee at a working pressure of 30 kPa, after the cooking starts, the preset ingredient parameter table is read to obtain the ingredient parameter A = 100a. During the heating-up stage, the portion parameter B = 9b is obtained through the portion judgment program. When the internal temperature T of the cooking appliance is detected to be 106 °C at the start of the exhaust stage, the total exhaust volume Dt = 100a * 9b * (106 - 100) * m = 5400abm at this time. Since the total exhaust volume becomes smaller and smaller as the exhaust duration progresses, when K_b ≤ Dt < K_s, that is, (K_b / (A * B * m) + F) ≤ T < (K_s / (A * B * m) + F), during the period when the internal temperature of the cooking appliance is 103 °C ≤ T < 106 °C, only the small hole is opened for exhaust while exhausting; when K_sb ≤ Dt < K_b, that is, (K_sb / (A * B * m) + F) ≤ T < (K_s / (A * B * m) + F), during the period when the internal temperature of the cooking appliance is 101 °C ≤ T < 103 °C, only the large hole is opened for exhaust while exhausting; when Dt = 0, when the internal temperature T of the cooking appliance is detected to be F, both the large and small holes are opened for exhaust for 5 seconds and then the exhaust stage ends.

[0070] This embodiment adaptively and dynamically adjusts the opening area of ​​the exhaust hole by comparing the total amount of gas generated at each moment in the exhaust stage with the exhaust area threshold, so that exhaust can be efficiently discharged in various cooking situations and the exhaust time is shortened.

[0071] In order to shorten the exhaust time while avoiding overflowing the pot, the exhaust time at different opening areas of the exhaust holes can also be controlled. Optionally, in the exhaust control method provided in the embodiment of the present application, the exhaust time of the cooking utensil at the exhaust holes of the first area is the first exhaust time, the exhaust time of the cooking utensil at the exhaust holes of the second area is the second exhaust time, and the exhaust time of the cooking utensil at the exhaust holes of the third area is the third exhaust time, wherein the first exhaust time is less than or equal to the second exhaust time, and the second exhaust time is less than or equal to the third exhaust time.

[0072] Among them, when the amount of gas generated is large, the cooking appliance is controlled to exhaust under the exhaust hole of the first area. Since overflow is likely to occur when the amount of gas generated is large, a shorter time is set for the first exhaust time to prevent overflow. Exemplarily, the range of the first exhaust time can be 0.1-0.5s.

[0073] Among them, when the amount of gas generated is moderate, the cooking appliance is controlled to exhaust at the exhaust hole of the second area. Since less gas needs to be exhausted when the amount of gas generated is moderate, overflow is not easy to occur. In order to improve the exhaust efficiency, the second exhaust time can be longer than the first time. For example, the second exhaust time can be in the range of 0.3-1s.

[0074] Among them, when the amount of gas generated is small, the cooking appliance is controlled to exhaust under the exhaust hole of the third area. Since there is basically no risk of overflow when the amount of gas generated is small, in order to further improve the exhaust efficiency, the third exhaust time can be longer than the second time. Exemplarily, the third exhaust time can range from 0.5-5s.

[0075] Through this embodiment, during the exhaust stage, a shorter exhaust time is set when the opening area of ​​the exhaust hole is smaller, a moderate exhaust time is set when the opening area of ​​the exhaust hole is moderate, and a longer exhaust time is set when the opening area of ​​the exhaust hole is larger, thereby achieving the effect of improving the exhaust efficiency and shortening the total exhaust time while preventing overflow.

[0076] In order to ensure safe opening of the lid, optionally, in the exhaust control method provided in the embodiment of the present application, the cooking appliance is controlled to exhaust according to the adjusted exhaust holes until the exhaust stage ends, including: controlling the cooking appliance to exhaust according to the adjusted exhaust holes until the gas volume is zero; when the gas volume is zero, adjusting the size of the area of ​​the exhaust holes to the maximum, and outputting a cooking completion signal after a preset time period.

[0077] It should be noted that when the gas volume is detected to be zero, if the exhaust hole is closed immediately, residual heat may be generated later, causing a pressure difference inside and outside the cooking appliance, and there is a safety hazard of scalding the user when the lid is opened. Therefore, after the gas volume is detected to be zero, this embodiment does not end the exhaust stage immediately, but outputs a cooking completion signal after controlling the exhaust hole to open for a preset time period to end the exhaust stage, wherein the preset time period can range from 1-10s.

[0078] Exemplarily, if the cooking appliance is provided with a large hole and a small hole for two exhaust holes, when the gas volume is detected to be zero, the large hole and the small hole can be opened at the same time for exhaust, and the large hole and the small hole can be closed after 5 seconds to output a cooking completion signal.

[0079] Through this embodiment, when the gas volume is detected to be zero, the area of ​​the exhaust hole is adjusted to the maximum, and the exhaust is terminated after a preset time period, thereby ensuring that all the gas in the cooking appliance is exhausted and improving the safety of opening the lid.

[0080] The embodiment of the present application also provides an optional exhaust control method.

[0081] Figure 4 is a flow chart of an optional exhaust control method according to an embodiment of the present application, such as Figure 4 As shown, the method includes:

[0082] Select a cooking function and start, read the preset food parameter table to obtain food parameter A. Among them, food parameter A represents the degree to which food is easy to overflow.

[0083] Determine whether to enter the heating stage, start counting num when entering the heating stage, determine whether to end the heating stage, and get the portion size according to the size of num when ending the heating stage, and read the preset portion parameter table to get the portion parameter B. Among them, the portion size of the food can be determined by the time it takes for the food to rise to a fixed temperature during the heating stage.

[0084] Determine whether to enter the exhaust stage. When entering the exhaust stage, detect the internal temperature T at every time t to obtain the total exhaust volume Dt = A*B*(TF)*m at time t. Among them, A is the value of the food parameter, B is the value of the component parameter, T is the temperature of the steam on the top of the cooking utensil, F is the boiling point, and m is the conversion factor, specifically the ratio of the unit gas volume to the unit gas volume parameter value. The pot body of the cooking utensil is provided with two exhaust holes, a large exhaust hole and a small exhaust hole. The opening area of ​​the exhaust hole can be adjusted by opening or closing the exhaust holes of different sizes.

[0085] It is determined whether the exhaust area is greater than a first preset exhaust area threshold. If the exhaust area is greater than the first preset exhaust area threshold, only the small hole is used for exhaust. It should be noted that when the amount of gas generated is large, in order to avoid overflow, only the small hole is used for exhaust, and the exhaust area is adjusted to a smaller area.

[0086] If the exhaust area is less than or equal to the first preset exhaust area threshold, it is determined whether the exhaust area is greater than the second preset exhaust area threshold. If the exhaust area is greater than the second preset exhaust area threshold, only the large hole is used for exhaust. It should be noted that when the amount of gas generated is moderate, less gas needs to be exhausted, and only the large hole is used for exhaust. The exhaust area is adjusted to a moderate area, and more gas is continuously discharged without overflowing.

[0087] If the exhaust area is less than or equal to the second preset exhaust area threshold, it is determined whether the exhaust area is greater than the third preset exhaust area threshold. If the exhaust area is greater than the third preset exhaust area threshold, it is determined that the large and small holes are used for exhaust at the same time. It should be noted that when the amount of gas generated is small, there is basically no risk of overflow. Exhausting with large and small holes at the same time and adjusting the exhaust area to a larger area can further improve the exhaust efficiency.

[0088] If the exhaust area is less than or equal to the third preset exhaust area threshold, it is determined whether Dt=0. If Dt is not 0, the large and small holes are used for exhaust at the same time. If Dt=0, the large and small holes are used for exhaust at the same time. The exhaust stage ends after 5 seconds. It should be noted that after the gas volume is detected to be zero, if the exhaust hole is closed immediately, residual heat may be generated later. In this embodiment, the exhaust stage ends after the exhaust hole is controlled to be open for a preset period of time to ensure that the user can open the lid safely.

[0089] Table 3 is a comparison table of exhaust time obtained by actual testing using conventional exhaust methods and the exhaust method of this embodiment for different cooking functions:

[0090] Table 3

[0091]

[0092] Among them, the conventional exhaust method refers to an exhaust method that does not adjust the opening area of ​​the exhaust hole during the exhaust stage. As shown in Table 3, in the cooking functions of fragrant porridge, pig's trotter and soybean soup, cooking rice and braised pork, the exhaust time actually tested by the exhaust method of this embodiment is shorter than that of the conventional exhaust method. The exhaust method of this embodiment periodically adjusts the size of the exhaust hole area of ​​the cooking appliance according to the amount of gas generated by the food during the exhaust stage, and exhausts according to the exhaust hole after the adjusted area, thereby achieving the effect of shortening the exhaust time and improving the exhaust efficiency while avoiding the overflow phenomenon.
