DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. They are only examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the attached claims.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0019] At present, there is a need to judge whether a liquid is boiling in all areas of life. For example, when boiling water in a kettle, it is most common to judge whether it has boiled to determine whether to stop boiling, or when using an induction cooker, the induction cooker adjusts the output power by judging whether the liquid in the pot is boiling. Among them, generally a temperature sensor is used to detect whether the temperature of the liquid has reached the boiling point to judge whether the heating process is over. However, there are certain limitations in judging by temperature. For example, the boiling point of the liquid will be affected by environmental factors, and the boiling point in high-pressure and low-pressure areas is different. The aging of the thermostat element and the long-term scale attached to the container affect the sensor detection, etc., resulting in deviations in the detected temperature value. These reasons will cause certain errors in judging whether the liquid is boiling by temperature, which is not accurate enough.

[0020] In view of this, the embodiments of the present application provide a liquid boiling detection method, device and storage medium. Figure 1 is an optional flow chart of a liquid boiling detection method provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps S101 to S104.

[0021] Those skilled in the art will appreciate that the technical solutions shown in the figures do not constitute a limitation on the embodiments of the present application, and may include more or fewer steps than shown in the figures, or a combination of certain steps, or different steps.

[0022] Step S101, obtaining the liquid level of the liquid in the target container, defining the liquid level when the heating process of the liquid is started as the initial height, and the liquid level is the height at which the liquid immerses the target position in the target container.

[0023] The method of this embodiment detects the liquid in the target container through a liquid detection device, wherein the shape of the target container is not limited, and the target container can be a pot, a cup or a basin, etc. On the other hand, this embodiment also does not limit the type of liquid, and the liquid in the target container can be water, oil or other organic solvents, etc. The liquid boiling detection device includes a metal detection bar 301 set on the outer wall of the target container and used to detect the height of the liquid. Through capacitive sensing, the actual liquid level detected is the height of the target position in the target container immersed in the liquid. The target position is determined according to the position of the metal detection bar. Figure 3 Taking the structure shown as an example, the target position is the inner wall of the target container in a certain direction. In other embodiments, if the liquid level in the target container is obtained by other forms of sensors, the target position may also be a position such as the center of the target container.

[0024] Specifically, when the heating process of the liquid in the target container is started, the method of this embodiment also starts to execute step S101 synchronously, obtains the liquid level of the liquid in the target container, and continuously monitors the value of the liquid level to determine its change until the heating process ends. Since the amount of liquid added to the target container by the user is different each time the heating process is started, the liquid level is also different. Therefore, in order to serve as a benchmark comparison in subsequent steps, the liquid level when the heating process is started is recorded as the initial height.

[0025] Step S102, when the difference between the liquid level and the initial height is greater than or equal to a preset difference, the pre-boiling stage is entered.

[0026] Optionally, when heating the liquid, the entire heating process can be divided into three stages. The first stage is the pre-boiling stage. In the pre-boiling stage, the properties of the liquid have not changed significantly, only the temperature has increased. The second stage is the pre-boiling stage. In the pre-boiling stage, due to the influence of the temperature approaching the boiling point, its properties begin to change significantly. This is also a suitable stage to start detecting whether it is boiling. The third stage is the boiling stage. In the third stage, the liquid has completely boiled. At this time, some properties of the liquid are compared with the conditions for judging whether it is boiling, that is, the detection of boiling is completed, and then the heating is continued to maintain boiling or the heating process is ended according to the specific product or user needs.

[0027] As for the pre-boiling stage, since the temperature of the liquid is close to the boiling point, the liquid will have obvious thermal expansion, so the liquid level will rise. Based on this, a preset difference is set to evaluate whether the liquid has the thermal expansion phenomenon. When the difference between the liquid level and the initial height is greater than or equal to the preset difference, it is determined that the thermal expansion phenomenon has occurred, so it is judged that the pre-boiling stage has begun, wherein the preset difference is set to 0.5 cm, etc. It should be noted that the pre-boiling stage is not just a stage for explanation. For the liquid boiling detection device, there is also a division of the pre-boiling stage in the step logic. Only when it is determined that the pre-boiling stage has begun, the subsequent steps are executed.

[0028] Step S103, in the pre-boiling stage, determining the liquid oscillation height according to the liquid level height.

[0029] When a liquid boils, bubbles are generated in the liquid. The bubbles will rise to the liquid surface, come into contact with the air and burst. When a large number of bubbles burst on the liquid surface, the liquid surface will fluctuate violently when boiling. Based on this phenomenon, the method of this embodiment determines the liquid oscillation height according to the liquid level. The liquid oscillation height is used to characterize the degree of fluctuation of the liquid surface. Its value is equivalent to the height difference of the fluctuation of the liquid surface. The degree of violent fluctuation of the liquid surface when the liquid boils can be quantitatively evaluated by the liquid oscillation height.

[0030] Step S104, when a preset condition is met, it is determined that the liquid is boiling, and the preset condition includes that the liquid oscillation height is greater than or equal to a preset height.

[0031] Furthermore, whether the liquid is boiling is determined by judging whether preset conditions are met. In the present embodiment, the preset conditions include that the liquid oscillation height is greater than or equal to a preset height. The preset height is set to, for example, 1 cm or 1.5 cm. Therefore, the liquid oscillation height is compared with the preset height. When the liquid oscillation height is greater than or equal to the preset height, it indicates that the fluctuation degree of the liquid surface is equivalent to that of the boiling stage, and the liquid is determined to be boiling.

[0032] In the steps S101 to S104 shown in the embodiment of the present application, by obtaining the liquid level of the liquid in the target container, the liquid level when the heating process starts is determined as the initial height. In the heating process, attention is paid to the change of the liquid level. When the difference between the liquid level and the initial height is greater than or equal to the preset difference, it is determined to enter the pre-boiling stage. Then, in the pre-boiling stage, the liquid level oscillation height is determined according to the liquid level, and it is determined whether the liquid level oscillation height is greater than or equal to the preset height. When it is judged to be yes, it is determined that the preset conditions are met and the liquid has boiled. Compared with detecting whether the liquid is boiling by temperature, the present application analyzes the boiling state of the liquid by the change of the liquid level, which can avoid the deviation problem caused by the influence of the boiling point on the environment or the aging of the thermostat element when judging by temperature, and improve the accuracy of detecting the boiling of the liquid.

[0033] In step S103 of some embodiments, the step of determining the liquid oscillation height according to the liquid level includes: The liquid oscillation height is determined according to the maximum and minimum values ​​of the liquid level within a preset time period.

[0034] Specifically, the preset time period is a time period before the current moment, such as within 1 second or within 2 seconds, etc. In the preset time period, the data of the liquid level height at multiple moments will be obtained based on the acquisition frequency of the liquid level height, and the liquid oscillation height corresponding to the preset time period will be determined according to the difference between the maximum value and the minimum value. If the liquid level does not fluctuate, it can be understood that the value of the liquid oscillation height is equal to zero or close to zero. If the liquid enters the boiling stage, the liquid level will fluctuate violently due to the impact of bubble bursting, and the liquid oscillation height will be a value significantly greater than zero. Moreover, as time goes by, the liquid level height data within the preset time period is updated, and the liquid oscillation height is also updated, thereby reflecting the real-time degree of liquid level fluctuation.

[0035] In other embodiments, the liquid oscillation height can also be determined based on the average value of the liquid level height within a preset time period, or the variance of the liquid level height within a preset time period can be calculated, and the variance can be used to perform subsequent judgment steps. The variance is also more conducive to reflecting the discreteness of the liquid level height.

[0036] By specifically calculating the value of the liquid oscillation height, the subsequent judgment of whether the liquid is boiling is supported, thereby improving the accuracy of boiling detection.

[0037] In step S104 of some embodiments, the method further includes: In the pre-boiling stage, the liquid oscillation frequency is determined according to the liquid level.

[0038] Furthermore, the preset conditions include that the liquid oscillation height is greater than or equal to a preset height, and the liquid oscillation frequency is greater than or equal to a preset frequency.

[0039] Furthermore, in addition to judging whether boiling occurs by the degree of fluctuation of the liquid level, the frequency of the fluctuation of the liquid level may also be used for judgment. Therefore, in this embodiment, the preset conditions include, in addition to the conditions for judging the liquid oscillation height in the above embodiment, the conditions for judging the liquid oscillation frequency. Only when both judgments are passed, is it determined that the preset conditions are met. Specifically, the preset conditions include that the liquid oscillation height is greater than or equal to the preset height, and the liquid oscillation frequency is greater than or equal to the preset frequency, wherein the liquid oscillation frequency is determined according to the numerical change of the liquid height, and the numerical value of the liquid oscillation frequency is equivalent to the frequency of the liquid surface fluctuation, and the preset frequency is set to, for example, 5 times per second or 10 times per second.

[0040] refer to Figure 2 In order to explain the judgment process of the preset conditions, Figure 2 In addition, step S201 is defined to determine the liquid oscillation height according to the liquid level height, and step S202 is defined to determine the liquid oscillation frequency according to the liquid level height, and step S203 is performed to determine whether the liquid oscillation height is greater than or equal to a preset height, and whether the liquid oscillation frequency is greater than or equal to a preset frequency. When the preset conditions are met, step S204 is executed to determine whether the liquid is boiling.

[0041] By combining the liquid oscillation height and the liquid oscillation frequency to quantitatively evaluate the degree of violent fluctuations of the liquid surface when the liquid boils, the preset conditions for judging whether the liquid is boiling are more accurate, thereby improving the accuracy of boiling detection.

[0042] In some embodiments, the step of determining the liquid oscillation frequency according to the liquid level comprises: Determine the change in liquid level between two adjacent moments.

[0043] When the change value is greater than or equal to the preset change value, the corresponding change value is determined to be a valid change.

[0044] The liquid oscillation frequency is determined by the number of effective changes per unit time.

[0045] Regarding how to determine the frequency of liquid level fluctuation, the first thing to consider is to eliminate the interference of general oscillations, such as physical collisions caused by the outside world, the impact of which is transmitted to the target container, or the target container itself shakes, which will cause the liquid in the target container to shake, that is, the liquid level will also change.

[0046] In order to eliminate the above-mentioned interference, the present embodiment first sets a preset change value, and the preset change value is set to, for example, 1 cm or 1.5 cm. Only when the change value between the liquid level heights collected at two adjacent moments is greater than or equal to the preset change value, the corresponding change value is determined to be a valid change. The preset change value is used for the situation where the target container itself is stationary and only the external physical influence is transmitted to the target container, causing the water to shake slightly. In this case, the slight change in the liquid level height caused by this situation is judged as an invalid change.

[0047] On the other hand, combined with the unit time length, for example 1s, the liquid oscillation frequency is determined according to the number of effective changes in the unit time length, which is actually equivalent to comparing the number of effective changes in the unit time length with the preset frequency in the above-mentioned preset conditions. The unit time length and the preset frequency can be used to target the situation where the target container itself shakes and causes the liquid in the target container to shake. It can be understood that the liquid level fluctuation during liquid boiling is compared with the liquid level fluctuation during shaking. The liquid level fluctuation caused by shaking has an obvious periodic regularity, and its frequency is also lower than that during boiling. Therefore, by setting the unit time length and the preset frequency to determine the liquid oscillation frequency, it can effectively avoid miscalculating the liquid level changes caused by liquid shaking, thereby improving the accuracy of boiling detection.

[0048] In some embodiments, step S102 of judging whether to enter the pre-boiling stage according to the liquid level can also be combined with the judgment of the liquid oscillation frequency, because the change of liquid level caused by shaking may also lead to misjudgment of the judgment. Specifically, in step S102, the above-mentioned step of determining the liquid oscillation frequency according to the liquid level can be added, and the judgment is changed to when the difference between the liquid level and the initial height is greater than or equal to the preset difference, and the liquid oscillation frequency is less than the target frequency, then entering the pre-boiling stage, wherein the liquid oscillation frequency less than the target frequency indicates that the liquid level is relatively stable at this time, without obvious fluctuations, and the liquid level rises only due to thermal expansion.

[0049] In step S104 of some embodiments, before determining whether a preset condition is met, the following step is further included: Get the heating power of the heating process and the preset parameters of the target container.

[0050] Determine the liquid volume based on the liquid level and preset parameters.

[0051] The preset height and the preset frequency are determined according to the heating power and the liquid volume.

[0052] On the other hand, the method of this embodiment determines whether the liquid is boiling by the liquid level oscillation height and the liquid level oscillation frequency. However, the boiling degree of the liquid, that is, the fluctuation of the liquid level is also affected by many factors, mainly the heating power and the liquid volume. Changes in these two factors will cause the same liquid to exhibit different liquid level fluctuations when boiling. Therefore, before making a judgment on the preset conditions, the heating power of the heating process and the preset parameters of the target container are first obtained, wherein the preset parameters are the shape parameters of the target container, such as the bottom area, etc. Based on this, the liquid volume can be calculated according to the liquid level height and the preset parameters, and the preset height and preset frequency used as the judgment standard are further determined according to the heating power and the liquid volume, so as to adjust the preset conditions according to the actual conditions of the heating and the liquid, thereby improving the accuracy of boiling detection.

[0053] In some embodiments, the step of determining the preset height and the preset frequency according to the heating power and the liquid volume comprises: The boiling characteristic mapping data is obtained, wherein the boiling characteristic mapping data includes a plurality of preset heights and preset frequencies mapped by heating power and liquid volume.

[0054] The first boiling level is determined according to the heating power, and the second boiling level is determined according to the liquid volume and the first boiling level.

[0055] The corresponding preset height and preset frequency are determined according to the first boiling level, the second boiling level and the boiling characteristic mapping data.

[0056] Regarding how to determine the preset height and preset frequency based on the heating power and the liquid volume, corresponding boiling characteristic mapping data are preset, wherein the liquid is divided into several levels according to the fluctuation of the liquid level when the liquid boils, each level is preset with a preset height and preset frequency corresponding to the level, and the corresponding level can be mapped by the heating power and the liquid volume.

[0057] Optionally, the first boiling level is first determined according to the heating power. For the sake of convenience, taking a table as an example, determining the first boiling level is equivalent to determining a specific row in the table, and then determining the second boiling level according to the liquid volume. Determining the second boiling level is equivalent to determining a specific column in the table. In this way, it is equivalent to determining the specific position in the table. The corresponding preset height and preset frequency can be determined according to the first boiling level, the second boiling level and the boiling characteristic mapping data, so as to make a judgment on the subsequent preset conditions, so that the preset conditions can be adjusted according to the heating power and the liquid situation, thereby further improving the accuracy of boiling detection.

[0058] In other embodiments, the preset difference used to determine the thermal expansion phenomenon can also be added to the boiling characteristic mapping data, and the preset difference corresponding to different heating powers and liquid volumes can be set. Optionally, the steps of this embodiment are adjusted to before step S102, and the corresponding preset height, preset frequency and preset difference are first determined according to the first boiling level, the second boiling level and the boiling characteristic mapping data, and then subsequent steps are performed.

[0059] In some embodiments, after the preset conditions are met, the method further includes: Start timing and define the timing duration as the boiling verification duration.

[0060] When the boiling verification time is greater than or equal to the preset time, the step of determining whether the liquid is boiling is performed.

[0061] In order to determine whether the liquid has fully boiled, the present embodiment sets a boiling verification time. When the preset conditions are met, the timing starts. The timing duration is the boiling verification time. When the boiling verification time is greater than or equal to the preset time, such as 10s or 15s, it is determined that the liquid has fully boiled, thereby ensuring the accuracy of boiling detection.

[0062] In some embodiments, after the step of starting the timing, the method further includes: During the timing of the boiling verification time, if the preset conditions are not met, the timing is ended and the boiling verification time is reset.

[0063] In addition, during the timing of the boiling verification time, it is also continuously verified whether the preset conditions are met, so as to avoid misjudgment of the preset conditions. Only when the boiling verification time is greater than or equal to the preset time and the preset conditions are always met, is it determined that the liquid is boiling. If it is determined during the timing process that the preset conditions are not met, the timing is ended and the boiling verification time is reset, and the judgment of the preset conditions in step S104 is repeated, so as to further ensure the accuracy of boiling detection.

[0064] The following is a detailed description and explanation of the solution of the embodiment of the present invention in conjunction with a specific application example: In an embodiment of the present application, a liquid boiling detection method is provided. The method obtains the liquid level of the liquid in the target container, and records the liquid level when the heating process of the liquid is started as the initial height. During the heating process, when the difference between the liquid level and the initial height is greater than or equal to a preset difference, the pre-boiling stage is entered.

[0065] In the pre-boiling stage, the liquid oscillation height is determined according to the maximum and minimum values ​​of the liquid level height within the preset time period. On the other hand, the change value between the liquid level heights collected at two adjacent moments is determined. When the change value is greater than or equal to the preset change value, the corresponding change value is determined to be an effective change. The liquid oscillation frequency is determined according to the number of effective changes within the unit time. The liquid oscillation height and the preset height, the liquid oscillation frequency and the preset frequency are compared respectively. When the liquid oscillation height is greater than or equal to the preset height, and the liquid oscillation frequency is greater than or equal to the preset frequency, it is determined that the preset conditions are met. At this time, the timing is started, and the timing duration is defined as the boiling verification duration. During the timing of the boiling verification duration, it is continuously determined whether the preset conditions are met. When the preset conditions are not met, the timing is ended and the boiling verification duration is reset. When the boiling verification duration is counted to be greater than or equal to the preset duration, it is determined that the liquid is boiling.
