Description

Control method and device for preventing dry burning of a pot, storage medium and cooktop

[0001] Cross-reference to related applications

[0002] The present disclosure claims priority to the Chinese patent application No. 202410456305.7, filed on April 16, 2024, and entitled "Control method and device for preventing dry burning of a pot, storage medium and cooktop", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of cooking appliances, and in particular to a control method and device for preventing dry burning of a pot, a storage medium and a cooktop. BACKGROUND

[0004] In the use of a pot, it is necessary for a user to be nearby to control it to avoid the occurrence of dry burning and other accidents.

[0005] In order to prevent dry burning of a pot, a dry burning start temperature threshold is set in the related art in a cooktop, and when the temperature of the pot is detected to reach the dry burning start temperature threshold, the cooktop is automatically turned off, thereby avoiding the occurrence of dry burning of the pot. However, the control precision of the dry burning prevention of the prior art is still not enough.

[0006] The applicant finds that the related art cannot accurately control the dry burning prevention of a pot, especially when the pot is being cooked with water, it is still not possible to accurately control it, and the dry burning prevention function is still started only when the water in the pot is burned out, which seriously affects the user experience and is likely to cause carbonization of food in a high temperature environment for a long time. The food that is severely carbonized is difficult to clean, and the smoke generated during dry burning also pollutes the indoor air, which seriously affects the service life of the pot.

[0041] Embodiments of the present disclosure are described in detail below with reference to the attached drawings, which are to be considered in conjunction with the entire disclosure and wherein like references are used throughout several views to designate like elements. The embodiments described below are merely examples used to explain the present disclosure and are not to be construed as limiting the present disclosure.

[0042] A control method and device for preventing dry boiling of a pot, a storage medium and a stove are described below with reference to the accompanying drawings.

[0043] Figure 1 is a flowchart of a control method for preventing dry boiling of a pot according to an embodiment of the present disclosure.

[0044] The control method for preventing dry boiling of a pot according to the present embodiment is applied to a stove 200 as shown in Figure 2, which has a pot 100 placed thereon. The control method for preventing dry boiling of the pot 100 according to the present embodiment can effectively prevent the pot 100 from dry boiling. The specific control method is described below.

[0045] The control method comprises the following steps:

[0046] S10, obtaining temperature information of the pot.

[0047] S20, determining that the pot is in a cooking state according to the temperature information.

[0048] S30, in response to the pot being in the cooking state, controlling the stove using a basic protection mode.

[0049] S40, confirming that the cooking state is a water cooking state.

[0050] S50, in response to the pot being in the water cooking state, controlling the stove using a water cooking protection mode or controlling the stove using both the basic protection mode and the water cooking protection mode, to prevent the pot from dry boiling.

[0051] Specifically, the temperature information of the pot can be obtained in real time. The temperature information of the pot can include temperature values, temperature change states, temperature prediction values and other temperature-related data. A temperature sensor can be provided on the stove to detect the temperature information of the pot. The temperature sensor can be provided on a device that contacts the pot, such as a pot rack, to ensure that the stove can accurately obtain the temperature information of the pot. After obtaining the temperature information of the pot, it can be determined whether the pot is in a water cooking state. If so, the stove is controlled using a water cooking protection mode to prevent the pot from dry boiling. It can be understood that whether the pot is in a water cooking state directly affects the dry boiling prevention mode of the pot. For example, if the pot is boiling noodles soup, the noodles soup may be boiled dry if the previous dry boiling prevention strategy is still used. The present embodiment uses a corresponding water cooking protection mode for this water cooking state, which can prevent the noodles soup from being boiled dry while preventing the pot from dry boiling. The related art does not determine the cooking state of the pot, but directly uses the same dry boiling start temperature threshold for dry boiling protection, which may result in early or untimely closing of the stove due to dry boiling misjudgment.

[0052] When the cooker is determined to be in the cooking state based on temperature information, the basic protection mode is used to control the cooker. When the cooking state is the water cooking state, the basic protection mode and the water cooking protection mode are used to control the cooker at the same time to prevent the cooker from burning dry.

[0053] Specifically, this embodiment can also use the basic protection mode to prevent dry cooking on the cooktop. Specifically, when the cooktop is in the cooking state, the basic protection mode can be directly used. There are multiple cooking states, such as water cooking state and waterless cooking state. When the cooking state is water cooking state, the basic protection mode and the water cooking protection mode can be used to control the cooktop simultaneously. It is understood that the basic protection mode and the water cooking protection mode can operate independently of each other, and when one protection mode has completed control of the cooktop, the other protection mode can be deactivated.

[0054] More specifically, as shown in FIG3 , the temperature of the pot is first collected, and then the stove is controlled simultaneously using the basic protection mode and the water cooking protection mode to determine whether the two modes meet the stove shutdown condition. If so, the stove can be controlled to shut down. Otherwise, the process returns to collecting the pot temperature. The two protection modes are independent of each other and can be two threads in two stove control devices.

[0055] In this embodiment, as shown in FIG4 , determining that the cookware is in a cooking state according to temperature information includes:

[0056] S401: Determine the temperature change state and current temperature value of the cookware according to the temperature information of the cookware.

[0057] S402: Determine whether the temperature change state of the cookware is an increasing state and the current temperature value exceeds a first preset temperature.

[0058] S403: In response to the fact that the temperature change state of the cookware is an increasing state and the current temperature value exceeds a first preset temperature, it is determined that the cookware is in a cooking state.

[0059] Specifically, after obtaining the temperature information of the pot, the temperature change state and current temperature value of the pot can be obtained from the temperature information, wherein the temperature change state can be information such as temperature rise and temperature drop. If the temperature change state is rising, it means that the current pot may be heated by the stove, so it can be further confirmed by the current temperature value. If the current temperature value exceeds the first preset temperature, it can be determined that the pot is in the cooking state. Optionally, the first preset temperature can be 100 degrees Celsius. That is to say, if the temperature of the pot is in a rising state and the temperature of the pot exceeds 100 degrees Celsius, then it can be determined that the pot is in the cooking state, and then the basic protection mode can be used to prevent dry burning.

[0060] In some embodiments of the present disclosure, as shown in FIG. 5, determining that the pot is in the water cooking state according to the temperature information comprises:

[0061] S501, determining a temperature change state and a current temperature value of the pot according to temperature information of the pot.

[0062] S502, determining that the temperature change state of the pot is a stable state and the stable state meets a preset condition and the current temperature value is less than a second preset temperature.

[0063] S503, in response to the temperature change state of the pot being a stable state and the stable state meeting a preset condition and the current temperature value being less than a second preset temperature, determining that the pot is in a water cooking state.

[0064] Specifically, for the judgment of the water cooking state, firstly, the temperature change state and the current temperature value of the pot need to be determined from the temperature information of the pot. Since the temperature change of the pot will not be too obvious if there is soup in the pot, it can be limited that the temperature change state of the pot is a stable state and the stable state meets a preset condition, and then it is further judged whether the current temperature value is less than a second preset temperature. If it is less than the second preset temperature, it can be determined that the pot is in a water cooking state. Optionally, the second preset temperature can be a preset water cooking temperature, and the second preset temperature is less than or equal to the first preset temperature, such as 90 degrees Celsius, 85 degrees Celsius or 80 degrees Celsius, etc.

[0065] In this embodiment, as shown in FIG. 6, the control method further comprises:

[0066] S601, calculating a steady state integral corresponding to each sub-period of the pot in a steady state determination period, the steady state determination period comprising a plurality of sub-periods.

[0067] S602, determining that the cumulative value of the steady state integral corresponding to each sub-period is greater than a preset cumulative value, the difference between the temperature value corresponding to the first sub-period and the temperature value corresponding to the last sub-period in the steady state determination period is less than a first preset temperature difference, and the range of the temperature values in the steady state determination period is less than a second preset temperature difference.

[0068] S603, in response to the cumulative value of the steady state integral corresponding to each sub-period being greater than a preset cumulative value, the difference between the temperature value corresponding to the first sub-period and the temperature value corresponding to the last sub-period in the steady state determination period being less than a first preset temperature difference, and the range of the temperature values in the steady state determination period being less than a second preset temperature difference, determining that the temperature change state of the pot is a stable state.

[0069] Specifically, as shown in FIG. 6, in the process of determining that the temperature change state of the pot is a stable state, the temperature information of the pot in the steady state determination period can be judged, and specifically, the steady state integral corresponding to the temperature information acquired each time by the pot, the temperature value, etc. can be judged. The steady state determination period includes a plurality of sub-periods, and each sub-period corresponds to a steady state integral. Specifically, the steady state integral of the detected temperature in the sub-period can be determined by looking up the table. Of course, one or more temperature values can be included in the sub-period. If one temperature value is included in the sub-period, the steady state integral corresponding to the sub-period can be directly determined according to the steady state integral corresponding to the temperature. If a plurality of temperature values are included in the sub-period, the average of the plurality of temperature values can be calculated first, and then the steady state integral corresponding to the average is used as the steady state integral corresponding to the sub-period. The temperature difference between the first sub-period and the last sub-period in the steady state period is also calculated, and specifically, the average temperature corresponding to the first sub-period and the last sub-period can be used as the temperature value of the period, and then the temperature difference is calculated based on the temperature value. The range of all the temperature values detected in the steady state period is also calculated. It can be understood that by calculating the difference between the temperature values of the first sub-period and the last sub-period, and calculating the range of the temperature values in the steady state determination period, the first and last temperature values and the intermediate temperature values collected in the steady state determination period can be accurately determined. When the cumulative value of the steady state integral of each sub-period is greater than the preset cumulative value, the temperature difference between the first and last sub-period is less than the first preset temperature difference, and the range of the temperature values in the steady state determination period is less than the second preset temperature difference, it can be determined that the temperature change state of the pot is a stable state.

[0070] More specifically, in some embodiments, the cumulative value of the steady state integral, the temperature difference between the first and last sub-period, and the range of the temperature values in the steady state determination period can be judged at the same time, or in a predetermined order. As shown in FIG. 7, in a specific embodiment, the temperature information cached in the steady state determination period is first read, and then the cumulative value of the steady state integral corresponding to each sub-period in the steady state determination period is judged. If yes, it is further judged whether the temperature difference between the first and last sub-period in the steady state determination period is less than the first preset temperature, and if yes, it is further judged whether the difference between the highest temperature and the lowest temperature in the steady state determination period is less than the second preset temperature, and if yes, it can be determined that the temperature change state of the pot is a stable state. If the above judgments are all in the state of no, it returns to the step of reading the temperature information cached in the steady state determination period. Alternatively, the first preset temperature difference and the second preset temperature difference in the embodiment can be valued according to actual application. For example, the first preset temperature can be 5 degrees Celsius, 4 degrees Celsius, 3 degrees Celsius, etc., and the second preset temperature difference can be 5 degrees Celsius, 6 degrees Celsius, 7 degrees Celsius, etc.

[0071] In some embodiments, as shown in FIG. 8, the calculation of the steady state integral corresponding to each sub-period in the steady state determination period includes:

[0072] S801, obtaining the range of temperature values in each sub-period.

[0073] S802, calculating the steady state integral corresponding to each sub-period according to the range of temperature values in each sub-period.

[0074] Specifically, the sub-period includes a plurality of temperature values, each of which corresponds to a steady state integral, so the sub-period includes a plurality of steady state integrals, and the specific way to determine the steady state integral of the sub-period according to the temperature values in the sub-period can be various, for example, the average value of the temperature values in the sub-period is used as the steady state integral of the sub-period. In this embodiment, the range of temperature values in the sub-period is used as the steady state integral of the sub-period. Of course, in other embodiments, other embodiments can also be used to determine the corresponding steady state integral of the sub-period.

[0075] More specifically, as shown in FIG. 9, ten sub-periods are included in a steady state determination period, and according to the temperature information of the steady state determination period, the average temperature of the first sub-period, the average temperature of the last sub-period, the maximum temperature of the whole period, the minimum temperature of the whole period, and the maximum and minimum temperature difference of each sub-period can be determined, so that the steady state integral corresponding to each sub-period can be determined according to the maximum and minimum temperature difference of each sub-period, then accumulated to obtain the accumulated value of the steady state integral, and the accumulated value is compared with the preset accumulated value, the difference between the average temperature of the first and last sub-period is compared with the first preset temperature difference, and the maximum and minimum temperature difference of the temperature value in the steady state determination period is compared with the second preset temperature difference. When the accumulated value is greater than the preset accumulated value, the difference between the average temperature of the first and last sub-period is less than the first preset temperature difference, and the maximum and minimum temperature difference of the temperature value in the steady state determination period is less than the second preset temperature, it can be determined that the temperature change state of the pot is stable.

[0076] In some embodiments of the present disclosure, the control method further includes: determining that the pot is in a stable state for a first preset duration and / or the discrete duration of the pot being in a stable state in a water cooking determination period exceeds a second preset duration; as a response to the pot being in a stable state for a first preset duration and / or the discrete duration of the pot being in a stable state in a water cooking determination period exceeding a second preset duration, determining that the stable state satisfies a preset condition, wherein the water cooking determination period includes at least one steady state determination period.

[0077] Specifically, after determining that the pot is in a stable state, it can be determined whether the stable state meets the preset condition. Specifically, the duration of the stable state of the pot can be determined. In the present embodiment, the duration of the stable state can include a continuous duration and a discrete duration, so two determination methods can be included. In the determination of the continuous duration, the continuous duration is compared with a first preset duration, and in the determination of the discrete duration, the sum of the discrete durations in the water cooking determination period is compared with a second preset duration. It can be understood that the water cooking determination period can include multiple stable state determination periods, as shown in FIG. 9, the water cooking determination period can include two stable state determination periods. If it is determined in the determination process that the continuous duration of the stable state is greater than or equal to the first preset duration, and / or the sum of the discrete durations of the stable state in the water cooking determination period is greater than or equal to the second preset duration, it can be determined that the stable state meets the preset condition. Alternatively, the first preset duration and the second preset duration can be determined according to the actual application scene. For example, the first preset duration can be 1 minute, 2 minutes, 3 minutes, etc., and the second preset duration can be 2 minutes, 3 minutes, 4 minutes, etc.

[0078] In some embodiments of the present disclosure, as shown in FIG. 10, the stove is controlled in a water cooking protection mode, including:

[0079] S1001, obtaining a temperature value corresponding to the pot when water in the pot boils.

[0080] S1002, determining a first protection temperature value of the pot according to the temperature value.

[0081] S1003, determining that the temperature of the pot exceeds the first protection temperature value.

[0082] S1004, in response to the temperature of the pot exceeding the first protection temperature value, controlling the stove to be turned off until the temperature of the pot does not exceed the first protection temperature value, and then clearing the control information of the stove.

[0083] Specifically, as shown in FIG. 10, in the process of controlling in the water cooking protection mode, first, it is determined that the temperature change state of the pot is a stable state, and after the determination is completed, it can be further judged whether the soup in the pot is boiling. If the soup in the pot boils, the temperature value corresponding to the pot can be further obtained, and then the first protection temperature value of the pot is determined according to the temperature value, and the first protection temperature value is compared with the temperature of the pot. If the temperature of the pot exceeds the first protection temperature value, it indicates that the pot needs to be protected from dry burning in the water cooking, that is, the stove is controlled to be turned off. After the control of the stove is completed, the temperature of the pot can be obtained, and when the temperature of the pot does not exceed the first protection temperature, the control information of the stove can be cleared, that is, the water cooking protection mode can be used again to control the pot to protect the pot from dry burning. Alternatively, the first protection temperature value can be determined according to the actual application scene, for example, the first protection temperature value can be 120 degrees Celsius, 130 degrees Celsius, etc.

[0084] More specifically, as shown in FIG. 11, first, the temperature of the pot is collected, and then whether the stove is in the ignition state is determined according to the temperature information of the pot. For example, when the temperature of the pot increases by 90 degrees Celsius within two minutes and the current temperature is greater than 100 degrees Celsius, it can be determined that the stove is in the ignition state. After the stove is in the ignition state, whether the pot is in the water cooking state is determined according to the temperature information of the pot. If the pot is in the water cooking state, the first protection temperature value of the pot in the water cooking boiling state is further obtained, and whether the temperature of the pot exceeds the first protection temperature value is determined. When it is determined that the temperature of the pot exceeds the first protection temperature value, the stove can be controlled to be turned off, and then the temperature of the pot is obtained under the condition that the stove is turned off to determine whether the temperature of the pot is lower than the first protection temperature value. If the temperature of the pot has gradually decreased to be lower than the first protection temperature value, the state data can be cleared to control the pot in the water cooking again, thereby protecting the pot. Of course, if it is determined that the stove is not in the ignition state, the state data can be directly cleared. If the determination result is negative in the above-mentioned other determination process, the pot can be returned to the state of collecting the temperature information of the pot to continue the water cooking protection control of the pot.

[0085] In another embodiment of the present disclosure, as shown in FIG. 12, the stove is controlled in the basic protection mode, which includes:

[0086] S1201, obtaining the time length of the pot in the cooking state and the temperature value of the pot.

[0087] S1202, determine whether the duration that the pot is in the cooking state is greater than a third preset duration and / or the temperature value of the pot exceeds a second protection temperature value.

[0088] S1203, in response to the duration that the pot is in the cooking state being greater than the third preset duration and / or the temperature value of the pot exceeding the second protection temperature value, control the stove to be closed.

[0089] Specifically, as shown in FIG. 12, in the process of controlling the stove in the basic protection mode, first, the duration that the pot is in the cooking state and the temperature value of the pot are obtained, and then when the duration that the pot is in the cooking state is long or the temperature value of the pot exceeds the preset value, the stove can be controlled to be closed to prevent the pot from being dry. The third preset duration and the second protection temperature value are specifically set for judgment, and when the duration that the pot is in the cooking state is greater than the third preset duration and / or the temperature value of the pot exceeds the second protection temperature value, the stove can be controlled to be closed. The third preset duration and the second protection temperature value can be determined according to actual application scenarios. Optionally, the third preset duration is 40 minutes, 45 minutes, 50 minutes, etc., and the second protection temperature value is 180 degrees Celsius, 190 degrees Celsius, 200 degrees Celsius, etc.

[0090] More specifically, as shown in FIG. 13, first, the temperature information of the pot is collected, and then whether the stove is in the ignition state is judged according to the temperature information of the pot. The judgment process is the same as judging whether the pot is in the cooking state in other embodiments. When it is determined that the stove is in the ignition state, whether the cooking duration of the stove is greater than the third preset duration is judged according to the temperature of the pot. If the cooking duration has exceeded the third preset duration, the stove can be directly controlled to be closed. If the cooking duration has not exceeded the third preset duration, whether the temperature of the pot is greater than the second preset protection temperature is further judged, and in the case that the temperature of the pot is greater than the second protection temperature value, the stove can also be controlled to be closed. In this specific embodiment, when it is judged that the temperature of the pot is not greater than the second protection temperature value, whether there is no pot on the stove is further judged according to the temperature of the pot. If yes, the protection temperature threshold in the no-pot state and the temperature of the stove probe are obtained. If the temperature of the stove probe exceeds the protection temperature threshold in the no-pot state, the stove is controlled to be closed to protect the stove probe. Otherwise, the temperature information of the pot is re-collected.

[0091] In one specific embodiment of the present disclosure, as shown in FIG. 14, after the stove is turned on, the temperature information of the pot is collected, and then it is determined whether the pot is in a cooking state according to the temperature information of the pot. If yes, the basic protection mode and the water cooking protection mode are executed at the same time to control the dry burning of the pot. In the basic protection mode, it is first determined whether the cooking time of the pot exceeds a third preset time. If yes, the stove can be directly controlled to be turned off to avoid the pot from being dry burned. If no, it is further determined whether the pot temperature exceeds a second protection temperature value. If yes, the stove can be controlled to be turned off to avoid the pot from being dry burned. If no, it is further determined whether the current stove is in a no-pot state according to the temperature rising rate of the pot. If the stove is in the no-pot state, it is determined whether the pot temperature exceeds a no-pot state protection temperature threshold. When the pot temperature is greater than the no-pot state protection temperature threshold, the stove is also controlled to be turned off to protect the fire supply probe in the stove. When it is determined that the stove is not in the no-pot state according to the temperature rising rate of the pot, or the stove is in the no-pot state but the pot temperature does not exceed the no-pot state protection temperature threshold, the temperature information of the pot is re-collected. In the water cooking protection mode, it is first determined whether the pot cooking state is water cooking. If yes, a first protection temperature value is determined according to the temperature of the pot in the steady state and the water boiling state. When the pot temperature exceeds the first protection temperature value, the stove is controlled to be turned off. Otherwise, the temperature information of the pot is re-collected.

[0092] In summary, the control method for preventing the pot from being dry burned in the embodiments of the present disclosure can accurately and effectively prevent the pot from being dry burned, reduce the cleaning difficulty and indoor pollution degree of the pot, and improve the service life of the pot and the user experience.
