Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a method and device for detecting the operation of a heating appliance, a heating appliance, a computer device, a computer-readable storage medium, and a computer program product. Background Art

[0002] As living standards improve, people's demands for healthier diets are becoming increasingly stringent. Various electrical appliances have emerged on the market, some of which require both weighing and heating functions. Heating is used to complete user-defined functions, such as cooking, steaming, and boiling water, while weighing is used to adjust the appliance's operation based on changes in weight. For example, when the weight is detected to increase and stabilize, it indicates that the user has added the corresponding ingredients or water, and only then will the appliance respond to the user's start trigger. Such appliances are widely used in the home appliance field, such as rice cookers, kettles, and various cooking appliances.

[0003] The weighing structure commonly used at present usually includes a metal shrapnel, which detects weight changes and produces corresponding deformation according to the size of the weight change. By measuring the deformation size of the shrapnel, the weight of the food or water added by the user to the appliance can be obtained, so as to adjust the operating status of the appliance accordingly.

[0004] However, the spring is significantly affected by temperature. When the temperature rises, it expands, causing changes in its geometry or elastic properties, resulting in large deviations in the detected weight. Even if a cooling fan is installed to cool the spring, the cooling effect is limited. The spring temperature is still affected by the heating of the appliance, which is an inevitable operating process. Therefore, for these appliances, improving the accuracy of heating appliance operation detection is an urgent problem to be solved. Summary of the Invention

[0005] Based on this, it is necessary to provide a heating appliance operation detection method, device, computer equipment, computer-readable storage medium and computer program product that can improve the accuracy of appliance operation detection in response to the above technical problems.

[0006] In a first aspect, the present application provides a method for detecting the operation of a heating appliance, the method comprising:

[0008] determining an operating state of the heating appliance based on the initial temperature and the temperature change trend;

[0009] When the weight data triggers the operating progress indicator of the heating appliance, whether the triggered operating progress indicator is reliable is determined according to the operating status to perform an operation detection on the heating appliance; the operating progress indicator is triggered based on the weight change detected during the operation of the heating appliance.

[0010] In this embodiment, the operating status of the heating appliance is classified by analyzing the numerical value and change trend of the temperature data of the heating appliance, and the triggered operating process indicators are processed differently based on different operating statuses to realize operation detection, reduce the operation detection deviation caused by the false triggering of the operating process indicators, and ensure the accuracy of the operation detection of the heating appliance.

[0024] When the initial indicator is hot and the temperature change trend is stable, it is determined that the operating state of the heating appliance is hot liquid.

[0028] In a case where the triggering time point is within the operation protection period of the heating appliance, the triggering reliability of the operation progress indicator is determined according to the operation state.

[0029] In this embodiment, the reliability of the operation process indicator is analyzed according to the triggering time point of the triggering operation process indicator, that is, when the triggering time point is within the operation protection period, the triggering reliability of the operation process indicator is determined according to the operation status, the operation of the heating appliance is analyzed more accurately, and corresponding operation detection is performed based on the subdivision, thereby ensuring the accuracy and reliability of the operation detection.

[0032] In a case where the triggering time point is in the operation protection period of the heating appliance, if the operation state is cold hot liquid or hot hot liquid, it is determined that the boiling index is reliable.

[0033] In this embodiment, when the heating appliance is in different operating states, different reliability analyses are performed on the indicators to be triggered, such as whether the boiling indicator is reliable, to determine whether the water in the heating appliance has reached a boiling state, thereby reducing the possibility of false triggering of the boiling indicator and improving the accuracy of operation detection.

The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0071] The heating appliance operation detection method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in FIG. , it is possible to perform operation detection on the heating appliance. This embodiment provides a heating appliance, such as Figure 1 As shown, a heating appliance includes a temperature sensor 102, a weight sensor 104, an appliance body 106 and a controller ( Figure 1 (not shown in the figure), the temperature sensor 102 and the weight sensor 104 are both provided on the appliance body 106, and the controller is connected to the temperature sensor 102, the weight sensor 104, and the appliance body 106. The temperature sensor 102 collects temperature data of the appliance body 106 of the heating appliance and transmits it to the controller. The weight sensor 104 collects weight data of the appliance body 106 of the heating appliance and transmits it to the controller. The controller performs operation detection based on the temperature data and weight data according to the heating appliance operation detection method described in each embodiment of the present application.

[0072] Specifically, the controller can be disposed within the appliance body, which is used to implement a heating function, performing the inherent function of the heating appliance through heating, such as cooking food or boiling water. The appliance body can include a heating element and a carrier. The carrier is placed on the heating element and has a cavity capable of holding food or water. The user can remove the carrier, place the corresponding food or water, and then place the carrier on the heating element. The heating element contains a heating element that can generate heat to heat the food or water placed within the carrier.

[0073] The temperature sensor is located on the side of the heating element near the support and is capable of detecting the temperature of the support, including but not limited to the initial temperature. The weight sensor is located on the heating element where the support is placed and is capable of detecting the weight of the support. The weight change of the support is continuously detected, allowing the controller to trigger corresponding operating progress indicators based on the weight change detected during operation of the heating appliance.

[0074] Furthermore, the number of temperature sensors can be multiple, capable of detecting the temperature data of the carrier and the heating temperature of the heating element. The heating temperature is transmitted to the controller for feedback on the heating status of the heating appliance. Exemplarily, the weight sensor includes a metal spring, which feedbacks weight changes through deformation.

[0075] The controller is connected to a temperature sensor to acquire temperature data, including the initial temperature, and analyze temperature change trends. It is also connected to a weight sensor to acquire weight data and, based on weight changes, trigger preset progress indicators to indicate the current progress of the heating appliance, such as when the water boils or when the next cooking stage begins. The controller is also connected to the appliance itself to control its heating, such as shutting it down or displaying corresponding progress indicators.

[0076] The present application provides a method for detecting the operation of a heating appliance, applicable to heating appliances with a weighing system and heating as their primary operating function. For example, these appliances can be electric kettles or rice cookers, which primarily operate with heating and can monitor their operation by detecting weight. For an electric kettle, during the heating process, the weight change of the water can be detected to determine whether the water is boiling. For a rice cooker, during the cooking process of rice or other ingredients, the weight change of the inner pot can be detected to analyze the cooking process and adjust the cooking process to achieve a better cooking effect.

[0077] In this application, an electric kettle will be taken as an example to illustrate the solution of this application, but it should be understood that the various embodiments recorded in this application are not limited to the application of heating appliances such as electric kettles, and are only used as exemplary illustrations for ease of understanding.

[0078] Illustratively, the present application provides a cast iron kettle that uses uncoated technology to avoid the problem of coated products causing health hazards after the coating falls off. The cast iron kettle includes a kettle and a base. The kettle is used to hold water, and the base is used to heat and identify the weight of the water. The heating method is that after the kettle is placed on the base, the heating plate of the base heats the bottom of the kettle, and the water volume is detected using a weighing system (including a shrapnel) in the base to detect the weight of the kettle. The working principle is that when the kettle is placed on the base after adding water, the shrapnel in the base detects that the normal weight range indicates that the kettle has been placed in place, and the heating function can be turned on. The operating process indicator includes a boiling indicator, which indicates that the water has boiled. Specifically, it means: during the heating process of the kettle, if it is detected that the amount of water evaporation meets certain conditions (for example, y grams of water have evaporated x times in a period of time, and x and y can be obtained based on historical experience or experimental data), it is considered that the water in the kettle has entered a boiling state, triggering the boiling indicator, and then the heating can be turned off accordingly, indicating that the boiling of water is complete.

[0079] However, the temperature of the spring element can cause detection errors. Consider adding a cooling fan to dissipate the heat from the base. However, the fan requires power to operate. If heat accumulates from repeated boiling and the power is turned off after the water is boiled, the fan cannot dissipate the heat from the base, causing the base temperature to gradually rise. This temperature increase affects the spring element within the base's weighing system, resulting in a large positive deviation in the measured weight. The metal spring element or other components expand when heated, causing changes in their geometry or elastic properties. This change causes the sensor to deform more under the same load, misinterpreting it as an increase in weight. This results in an increase in weight reading, even when the water volume remains unchanged, leading to an erroneous weight reading. If the device is powered on and begins heating, and the cooling fan is activated during the heating process, the base temperature drops and the weight error gradually recovers. This weight change then coincides with the evaporation rate, leading to a "false boiling" phenomenon. This means that after heating begins, the water does not boil, but an abnormal weight change is detected, causing the heating process to terminate. This erroneous detection of the heating process seriously affects the user experience and may even endanger user health.

[0080] To this end, in an exemplary embodiment, Figure 2 As shown, a method for detecting the operation of a heating appliance is provided, which is applied to Figure 1 The controller in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 202 to 206. Among them:

[0081] Step 202 : Obtain weight data of the heating appliance and the initial temperature of the heating appliance, and determine a temperature change trend of the heating appliance after the heating appliance runs for a preset operating time.

[0082] Among them, the weight data is the weight of the heating appliance detected by the weight sensor. As the heating appliance runs, the weight data continues to increase, including and recording the weight at different times and the weight change. The initial temperature refers to the temperature detected by the heating appliance at the beginning of this operation. When the heating appliance includes a heating element and a carrier, the initial temperature refers to the temperature detected at the carrier. For example, the kettle and base of a cast iron kettle, when the kettle is placed on the base and the user triggers the boiling water command, the detected temperature of the kettle is the initial temperature. The preset running time refers to a set time point, starting from the start of this operation, and when the set running time is reached, it is called the preset running time of the heating appliance. For example, the preset running time can be 1 minute.

[0083] Specifically, the controller is connected to the temperature sensor and can transmit data to each other. It can control the operation of the temperature sensor and obtain the temperature data collected by the temperature sensor. Among multiple temperature data, the temperature data when the heating appliance is started this time is used as the initial temperature. According to the running time of the heating appliance, after it runs for a preset running time, the temperature data within the preset running time is comprehensively analyzed to determine the temperature change trend of the heating appliance.

[0084] Optionally, the controller can be a control chip of the heating appliance. When the user triggers different commands of the heating appliance, the controller receives the commands and takes corresponding actions to complete the operation control of the heating appliance. The controller can also be an auxiliary chip additionally provided in the heating appliance, interacting with the control chip of the heating appliance to obtain the operating status of the heating appliance, such as whether it is running and heating.

[0085] Furthermore, in an exemplary embodiment, Figure 3 As shown, step 202 includes steps 302 to 306. Among them:

[0086] Step 302: Obtain weight data of the heating appliance and the initial temperature of the heating appliance.

[0087] Specifically, the controller is connected to a temperature sensor and a weight sensor, interacting with the weight sensor to obtain weight data collected by the weight sensor; and interacting with the temperature sensor to obtain the initial temperature of the heating appliance collected by the temperature sensor. Alternatively, the controller can activate the heating appliance when the weight data falls within a set weight range. Alternatively, the controller can activate the temperature sensor simultaneously with the activation of the heating appliance, using the first temperature data collected by the temperature sensor after activation as the initial temperature of the heating appliance.

[0088] Step 304 : After the heating appliance runs for a preset time, the initial temperature of the heating appliance is obtained.

[0089] Specifically, the preset operating time has been described above and will not be further described here. After the heating appliance has run for the preset operating time, the controller has accumulated temperature data collected during the preset operating time and then determines the initial temperature of the heating appliance based on the temperature data collected during the preset operating time. For example, the preset operating time may be 1 minute.

[0090] Optionally, there are several methods for obtaining the initial temperature of the heating appliance based on the temperature data during the preset operating time. A first method is to perform a calculation on the temperature data during the preset operating time, including but not limited to mathematical operations such as averaging or median, to obtain a calculated temperature as the initial temperature of the heating appliance. A second method is to use the last temperature data during the preset operating time as the initial temperature of the heating appliance.

[0091] Step 306: Determine the temperature change trend of the heating appliance based on the initial temperature and the initial temperature.

[0092] Specifically, after determining the initial temperature and the initial stage temperature, the controller determines the temperature change trend of the heating appliance based on the temperature difference between the initial temperature and the initial stage temperature. For example, the temperature difference is calculated by subtracting the initial temperature from the initial stage temperature, and the temperature difference is used as the temperature change trend data.

[0093] Different temperature change trends can be obtained based on the size of the temperature difference. For example, different temperature rise gears can be set, and different temperature change gears can be corresponding to different calculated temperature differences, thereby determining the corresponding temperature change trends.

[0094] For example, in one embodiment, if the temperature difference between the initial temperature and the initial stage temperature obtained by the controller is a positive value, the value is greater than 3 degrees Celsius and less than or equal to 5 degrees Celsius, it can be considered that the temperature change is small, and the temperature change trend of the heating appliance is determined to be slow heating. In one embodiment, if the temperature difference between the initial temperature and the initial stage temperature obtained by the controller is a positive value, the value is greater than 5 degrees Celsius and less than or equal to 10 degrees Celsius, it can be considered that the temperature change is large, and the temperature change trend of the heating appliance is determined to be rapid heating. In one embodiment, if the temperature difference between the initial temperature and the initial stage temperature obtained by the controller is a negative value, the value is greater than 3 degrees Celsius and less than or equal to 10 degrees Celsius, it can be considered that the temperature change is negative, and the temperature change trend of the heating appliance is determined to be cooling. In one embodiment, if the temperature difference between the initial temperature and the initial stage temperature obtained by the controller is a positive or negative value, and the value is less than or equal to 3 degrees Celsius, it can be considered that the temperature change is not large, and the temperature change trend of the heating appliance is determined to be stable.

[0095] In this embodiment, the initial temperature of the heating appliance is obtained, and the initial temperature is obtained after the heating appliance runs for a preset time. Multiple temperature data are analyzed to obtain the temperature change trend of the heating appliance. By accurately obtaining the temperature change trend, the accuracy of subsequent operation detection of the heating appliance is guaranteed.

[0096] Step 204: Determine the operating state of the heating appliance based on the initial temperature and the temperature change trend.

[0097] Specifically, after obtaining the initial temperature and the temperature change trend, the controller can determine the operating state of the heating appliance through a comprehensive analysis based on the initial temperature and the combination of the temperature change trends. Taking into account the temperature of the object to be heated by the heating appliance and the temperature of the heating appliance itself, based on the applicant's observation of the operation of the heating appliance, the following operating states can be obtained: the heating object is cold and the heating appliance is cold; the heating object is hot but the heating appliance is cold; the heating object is cold but the heating appliance is hot; and the heating object is hot and the heating appliance is hot.

[0098] Specifically, in an exemplary embodiment, Figure 4 As shown, step 204 includes steps 402 to 404. Among them:

[0099] Step 402: Determine the initial index of the heating appliance based on the initial temperature and the initial judgment threshold.

[0100] The controller stores an initial judgment threshold value, which is a set temperature value used for comparison with the initial temperature. The controller can determine the initial indicator corresponding to the initial temperature based on the comparison result. For example, the initial judgment threshold value can be an arbitrary temperature, such as 30 degrees Celsius. When the initial temperature is lower than 30 degrees Celsius, the initial indicator of the heating appliance can be determined to be cold; when the initial temperature is higher than or equal to 30 degrees Celsius, the initial indicator of the heating appliance can be determined to be hot.

[0101] Specifically, after obtaining the initial temperature, the controller compares the initial judgment threshold with the initial temperature and, based on the comparison result, determines the initial indicator of the heating appliance during this operation, such as whether the initial indicator is cold or hot. This initial indicator can specifically represent the temperature of the heating appliance. For example, if a kettle has just been filled with water for heating and the water temperature has not yet fully transferred to the kettle, the initial temperature detected by the temperature sensor is the temperature of the kettle surface, which is also the temperature of the heating appliance. If the kettle becomes boiling hot due to repeated boiling, the corresponding initial temperature detected will be the higher temperature of the kettle surface.

[0102] Step 404: Determine the operating status of the heating appliance based on the initial indicator and the temperature change trend.

[0103] Specifically, after the controller determines the initial indicator and temperature trend, it combines and analyzes the initial indicator and temperature trend to determine the different operating states of the heating appliance. The initial indicator represents the initial state of the heating appliance, while the temperature trend represents the state of the object being carried, such as water or food. Combining the two, the operating state of the heating appliance can be analyzed.

[0104] In this embodiment, by determining different initial indicators based on the initial judgment threshold value according to the initial temperature, the initial operating state of the heating appliance is confirmed, and then the operating state of the heating appliance can be determined according to the temperature change trend. The operating state of the heating appliance is subdivided from the perspective of temperature data to facilitate subsequent accurate detection of the operation of the heating appliance.

[0105] Furthermore, in an exemplary embodiment, Figure 5 As shown, step 404 includes steps 502 to 508. Among them:

[0106] Step 502: When the initial indicator is cold and the temperature change trend is a slow rise, determine that the operating state of the heating appliance is cold liquid.

[0107] Step 504 : When the initial indicator is cold and the temperature change trend is rapid heating, it is determined that the operating state of the heating appliance is cold hot liquid.

[0108] Step 506 : When the initial indicator is hot and the temperature change trend is cooling, determine that the operating state of the heating appliance is hot cold liquid.

[0109] Step 508 : When the initial indicator is hot and the temperature change trend is stable, determine that the operating state of the heating appliance is hot liquid.

[0110] Specifically, if the initial indicator is cold, indicating that the initial temperature of the heating appliance is low, if the temperature trend shows a slow increase after the preset operating time, it can be assumed that the temperature of the water or food heated by the heating appliance is also low. For a cast iron kettle, both the kettle temperature and the water temperature are low, indicating the state of a cold kettle filled with cold water. Therefore, the operating state of the heating appliance is confirmed to be cold liquid.

[0111] If the initial indicator is cold, indicating the heating appliance's initial temperature is low, then if the temperature rises rapidly after the preset operating time, it can be assumed that the water or food being heated by the heating appliance is relatively high, and the heat is dissipated to the heating appliance as it heats, resulting in a rapid temperature rise. For a cast iron kettle, this means the kettle temperature is relatively low, but the water inside is relatively high, like a cold kettle containing hot water. This indicates that the heating appliance is operating in a cold hot liquid state.

[0112] When the initial indicator is hot, indicating that the initial state temperature of the heating appliance is high, if the temperature trend is cooling after running for the preset operating time, it can be assumed that the temperature of the water or food heated by the heating appliance is low. While being heated by the heating appliance, they absorb the heat of the heating appliance itself, driving the temperature of the heating appliance down, causing the temperature data detected by the temperature sensor to drop. For a cast iron kettle, the kettle may be high due to repeated heating, but the temperature of the water inside the kettle is low. The water absorbs heat, causing the temperature of the kettle to drop within the preset operating time, which is the state of a hot water kettle filled with cold water. Therefore, the operating state of the heating appliance is confirmed to be hot cold liquid.

[0113] If the initial indicator is "hot," indicating a high initial temperature, if the temperature trend remains stable after the preset operating time, it can be assumed that the temperature of the water or food being heated by the heating appliance is also high, and that the heating by the heating appliance during the preset operating time has had little impact on either temperature. For a cast iron kettle, if both the kettle and the water are high, indicating a hot water kettle, the operating state of the heating appliance is confirmed to be "hot liquid."

[0114] In this embodiment, different operating states are determined based on different initial indicators and temperature change trends, the operating conditions of the heating appliance are subdivided, and the operation of the heating appliance is accurately analyzed from the temperature dimension, so as to facilitate the subsequent judgment of the triggered operating process indicators, which is conducive to improving the accuracy of operation detection.

[0115] Step 206 : When the weight data triggers the operation progress indicator of the heating appliance, whether the triggered operation progress indicator is reliable is determined according to the operation status, so as to perform an operation test on the heating appliance.

[0116] The heating appliance is pre-programmed with operating progress indicators corresponding to different operating states. These indicators are triggered by different conditions, such as temperature changes or weight changes. When these conditions are met, the indicator triggers, indicating that the heating appliance has reached its operating state and providing real-time feedback on the appliance's operation. The indicator is triggered based on changes in weight data detected during operation. A weight sensor detects changes in the weight of the heating appliance during operation. When the heating temperature of the heating device reaches a certain value, the water inside the appliance evaporates, reducing its weight. The weight sensor monitors the appliance's operation by detecting changes in its weight during operation and triggers the indicator when the weight change meets the trigger condition.

[0117] Specifically, when triggering the heating appliance's operating progress indicator, the controller adds a judgment logic to determine whether the triggered operating progress indicator is reliable and accurate based on the operating status. After completing the judgment, corresponding processing is performed to ensure accurate operation detection of the heating appliance.

[0118] For example, for a cast iron kettle, the operating progress indicator can be an indicator indicating that the water in the kettle has boiled, also known as a boiling indicator. The trigger condition is that the amount of water evaporation in the kettle meets a set threshold within a set time period, that is, the amount of water decreases by y grams x times consecutively within a period of time. The amount of water evaporation is determined by detecting changes in the kettle's weight using a weight sensor.

[0119] The above-mentioned heating appliance operation detection method includes obtaining the weight data and initial temperature of the heating appliance, determining the temperature change trend of the heating appliance after the heating appliance has been running for a preset period of time, and determining the operating status of the heating appliance based on the initial temperature and temperature change trend. When the weight data triggers the operating progress indicator of the heating appliance, the reliability of the triggered operating progress indicator is determined based on the operating status to perform operation detection on the heating appliance. By analyzing the numerical value and change trend of the temperature data of the heating appliance, the operating status of the heating appliance is classified. The triggered operating progress indicator is processed differently based on different operating states to achieve operation detection, reducing operation detection deviations caused by false triggering of the operating progress indicator and ensuring the accuracy of heating appliance operation detection.

[0120] In an exemplary embodiment, Figure 6 As shown, step 206 includes steps 602 to 604 .

[0121] in:

[0122] Step 602: When the weight data triggers the operating progress indicator of the heating appliance, a triggering time point is determined.

[0123] Specifically, the controller's reliability judgment of the operating progress indicator based on the operating status may not be present throughout the entire process. In order to appropriately reduce the computing load or reduce the power consumption of the heating appliance, the operating status can be enabled only during a specified time period to analyze the operating progress indicator. To this end, when triggering the operating progress indicator of the heating appliance, it is necessary to determine a trigger time point that matches the operating progress indicator based on the trigger time. The trigger time point is used to represent the trigger time of the operating progress indicator and can be timed based on the start-up time of the heating appliance to facilitate subsequent comparative analysis of the time dimension.

[0124] Step 604 : When the triggering time point is within the operation protection period of the heating appliance, the triggering reliability of the operation process indicator is determined according to the operation state.

[0125] Specifically, the controller stores the heater's operating protection period. This period is a set time period starting from the heater's startup, typically during the early stages of the heater's startup. This period is used to reduce the risk of false triggering of the heater's operating progress indicator. Upon receiving a trigger for the operating progress indicator, the controller determines the trigger time and analyzes whether the trigger time falls within the heater's operating protection period.

[0126] If the triggering time point is within the operation protection period of the heating appliance, it is necessary to determine the triggering reliability of the operation progress indicator based on the operating status, that is, to determine whether the operation progress indicator is reliable. If the triggering time point is not within the operation protection period of the heating appliance, there is no need to analyze the triggering reliability of the operation progress indicator based on the operating status, and the operation of the heating appliance can be directly characterized by the triggered operation progress indicator.

[0127] In this embodiment, the reliability of the operation process indicator is analyzed according to the triggering time point of the triggering operation process indicator, that is, when the triggering time point is within the operation protection period, the triggering reliability of the operation process indicator is determined according to the operation status, the operation of the heating appliance is analyzed more accurately, and corresponding operation detection is performed based on the subdivision, thereby ensuring the accuracy and reliability of the operation detection.

[0128] In an exemplary embodiment, the operating states may be divided according to the above-mentioned embodiments, and the operating states include cold liquid, cold hot liquid, hot liquid, and hot hot liquid. The operating progress indicator is a boiling indicator, and step 206 includes steps 702 to 704.

[0129] Step 702: When the triggering time point is in the operation protection period of the heating appliance, if the operation state is cold liquid or hot liquid, determine that the boiling index is unreliable.

[0130] Step 704 : When the triggering time point is in the operation protection period of the heating appliance, if the operation state is cold hot liquid or hot hot liquid, determine that the boiling index is reliable.

[0131] Specifically, for a cast iron kettle, if the operating state is cold liquid or hot liquid, the heat absorbed during the operation protection period is not enough to make the water in the kettle boil; if the weight change detected during the operation protection period meets the evaporation judgment condition and the boiling index is triggered, it is considered that this is a false boiling phenomenon, the boiling index is unreliable, and it is not judged as boiling. For the operating state of cold hot liquid or hot hot liquid, since the water in the kettle itself has a higher temperature, it is normal for it to boil during the operation protection period. If the weight change detected during the operation protection period meets the evaporation judgment condition and the boiling index is triggered, it is considered that this is a real boiling phenomenon, the boiling index is reliable, and the controller judges that it is boiling at this time. After boiling is judged, the heating appliance can also be controlled to stop heating to improve the convenience and intelligence of the heating appliance.

[0132] In this embodiment, when the heating appliance is in different operating states, different reliability analyses are performed on the indicators to be triggered, such as whether the boiling indicator is reliable, to determine whether the water in the heating appliance has reached a boiling state, thereby reducing the possibility of false triggering of the boiling indicator and improving the accuracy of operation detection.

[0133] In an exemplary embodiment, the controller may also obtain the abnormal heating operation state according to the temperature data, and the heating appliance operation detection method at this time further includes steps 802 to 804.

[0134] Step 802: Based on the initial temperature or the temperature change trend, determine that the operating state of the heating appliance is abnormal.

[0135] Specifically, when the initial temperature is too high, or the temperature change trend exceeds the temperature change level, the heating appliance's operating state can be considered abnormal. For example, in conjunction with the aforementioned embodiment, when the initial temperature is less than 100 degrees Celsius, the initial temperature is considered normal, and when the initial temperature is greater than or equal to 100 degrees Celsius, the initial temperature can be considered too high. When the temperature change trend indicates that the temperature difference between the initial temperature and the initial stage temperature exceeds 10 degrees Celsius within a preset operating time, the temperature change trend can be considered to have exceeded the temperature change level.

[0136] When either of the above two conditions is met, the controller can determine that the operating state of the heating appliance is abnormal.

[0137] Step 804: Control the heating appliance to stop running and output a warning message.

[0138] Specifically, upon determining that the operating state of the heating appliance is abnormal, indicating a fault in the heating appliance, the controller controls the heating appliance to stop operating and exit heating, and simultaneously outputs a warning message to prompt the user and alert the user so that the user can promptly repair the appliance. The warning message can be output through a display screen, indicator light, digital tube, buzzer, etc., as long as it can prompt the user.

[0139] In this embodiment, by analyzing the temperature data from multiple angles, emergency shutdown and alarm are taken for abnormal operating conditions to ensure the safe operation of the heating appliance, thereby achieving the protection of the safety of the heating appliance while performing operational detection on the heating appliance.

[0140] Based on the same technical concept, the present application provides a heating appliance, such as Figure 1 As shown, a heating appliance includes a temperature sensor 102, a weight sensor 104, an appliance body 106 and a controller ( Figure 1 (not shown in the figure), the temperature sensor 102 and the weight sensor 104 are both provided on the appliance body 106, and the controller is connected to the temperature sensor 102, the weight sensor 104, and the appliance body 106. The temperature sensor 102 collects temperature data of the appliance body 106 of the heating appliance and transmits it to the controller. The weight sensor 104 collects weight data of the appliance body 106 of the heating appliance and transmits it to the controller. The controller performs operation detection based on the temperature data and weight data according to the heating appliance operation detection method described in each embodiment of the present application.

[0141] Specifically, the appliance body is used to perform a heating function, performing the inherent function of a heating appliance through heating, such as cooking food or boiling water. The appliance body may include a heating element and a carrier. The carrier is placed on the heating element and has a cavity capable of holding food or water. The user can remove the carrier, place the corresponding food or water, and then place the carrier on the heating element. The heating element contains a heating element that generates heat to heat the food or water placed in the carrier.

[0142] The temperature sensor is located on the side of the heating element near the support and is capable of detecting the temperature of the support, including but not limited to the initial temperature. The weight sensor is located on the heating element where the support is placed and is capable of detecting the weight of the support. The weight change of the support is continuously detected, allowing the controller to trigger corresponding operating progress indicators based on the weight change detected during operation of the heating appliance.

[0143] Furthermore, the number of temperature sensors can be multiple, capable of detecting the temperature data of the carrier and the heating temperature of the heating element. The heating temperature is transmitted to the controller for feedback on the heating status of the heating appliance. Exemplarily, the weight sensor includes a metal spring, which feedbacks weight changes through deformation.

[0144] The controller is connected to a temperature sensor to acquire temperature data, including the initial temperature, and analyze temperature change trends. It is also connected to a weight sensor to acquire weight data and, based on weight changes, trigger preset progress indicators to indicate the current progress of the heating appliance, such as when the water boils or when the next cooking stage begins. The controller is also connected to the appliance itself to control its heating, such as shutting it down or displaying corresponding progress indicators.

[0145] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0146] In one embodiment, a cast iron kettle is provided that utilizes coating-free technology, avoiding the health hazards associated with coated products when the coating falls off. The cast iron kettle comprises a kettle and a base. The kettle is used to hold water, while the base is used to heat and identify the weight of the water. The heating method is that after the kettle is placed on the base, the base's heating plate heats the bottom of the kettle. The water level is detected using a weighing system (including a spring) within the base to detect the kettle's weight. The operating principle is that when the kettle is filled with water and placed on the base, the spring within the base detects a normal weight range, indicating that the kettle has been placed in place. The heating function can then be turned on. The operating progress indicator includes a boiling indicator, indicating that the water has boiled. Specifically, during the kettle heating process, if the amount of water evaporation is detected to meet certain conditions (e.g., y grams of water evaporated x times consecutively over a period of time, where x and y can be derived based on historical experience or experimental data), the water in the kettle is considered to have entered a boiling state, triggering the boiling indicator. The heating function can then be turned off accordingly, indicating that the water has been boiled.

[0147] However, the temperature of the spring element can cause detection errors. Consider adding a cooling fan to dissipate the heat from the base. However, the fan requires power to operate. If heat accumulates from repeated boiling and the power is turned off after the water is boiled, the fan cannot dissipate the heat from the base, causing the base temperature to gradually rise. This temperature increase affects the spring element within the base's weighing system, resulting in a large positive deviation in the measured weight. The metal spring element or other components expand when heated, causing changes in their geometry or elastic properties. This change causes the sensor to deform more under the same load, misinterpreting it as an increase in weight. This results in an increase in weight reading, even when the water volume remains unchanged, leading to an erroneous weight reading. If the device is powered on and begins heating, and the cooling fan is activated during the heating process, the base temperature drops and the weight error gradually recovers. This weight change then coincides with the evaporation rate, leading to a "false boiling" phenomenon. This means that after heating begins, the water does not boil, but an abnormal weight change is detected, causing the heating process to terminate. This erroneous detection of the heating process seriously affects the user experience and may even endanger user health.

[0148] There are two temperature sensors on the base of the electric kettle, the bottom temperature sensor and the side temperature sensor. The bottom temperature sensor is used to detect the temperature and control the switching of the heating power, and the side temperature sensor is used to detect whether the kettle is dry-boiling.

[0149] This solution improves upon the control method developed for kettles. Beyond this product, the control logic can also be applied to other products that share the same principle, such as weighing rice cookers. The kettle's base has two temperature sensors: a bottom sensor and a side sensor. The bottom sensor detects temperature and controls heating power levels, while the side sensor detects dry-boiling.

[0150] Real-time monitoring of the temperature sensor temperature allows for intelligent judgment of different boiling states. Different boiling process judgments are performed based on the boiling state, and false boiling phenomena can be intelligently filtered out, thereby accurately judging the boiling state. If the cold water boiling situation meets the evaporation conditions at the beginning of the boiling phase (e.g., within 3 minutes, the actual data is obtained based on experiments), and a false boiling phenomenon occurs due to the weight sensor detection deviation, the evaporation judgment will be filtered out and the boiling process will not begin. The judgment conditions for each boiling state are as follows:

[0151] Case 1 (Cold kettle cold water judgment condition): When it is detected that the kettle is full of water and starts to boil water, the temperature of the side temperature sensing package is detected to be cold when the water starts to boil (such as the side temperature sensing package temperature t<30℃, the actual data is obtained according to the experiment), and the temperature change within a period of time when the water starts to boil is detected, such as a temperature rise of 5℃ within 1 minute (calculation method: the temperature value detected after a period of time minus the temperature value before a period of time, the actual data is obtained according to the experiment) and it is a positive value, that is, the temperature is on an upward trend and the temperature rise is slow. It is considered that this is a cold kettle cold water boiling situation. Within a period of time before the boiling work starts (such as within 2 minutes, the actual data is obtained according to the experiment), if the weight change is detected to meet the evaporation judgment condition, it is considered to be a false boiling phenomenon, and it is not judged as boiling. Continue heating. After a period of time (such as 2 minutes), the evaporation boiling condition is judged.

[0152] Case 2 (Cold kettle hot water judgment condition): When it is detected that the kettle is full of water and starts to boil water, the temperature of the side temperature sensor is detected to be cold (such as the side temperature sensor temperature t<30℃, the actual data is obtained according to the experiment), and the temperature changes within a period of time when the water starts to boil, such as rising by 10℃ in 1 minute (calculation method: the temperature value detected after a period of time minus the difference between the temperature values ​​before a period of time, the actual data is obtained according to the experiment) and it is positive, that is, the temperature is on an upward trend and the temperature rises faster (the reason is that when hot water is added to the cold kettle, the hot water temperature is transferred to the kettle body, and there is a heat superposition to heat the boiling water. In the early stage of boiling water, the temperature rise will be faster than that of boiling water with cold water in a cold kettle). It is considered to be a cold kettle hot water boiling situation. If it is detected that the evaporation amount meets the boiling conditions during the whole process of boiling water, it is judged that the water has boiled, and the heating state is exited and the insulation is entered.

[0153] Case 3 (Hot kettle cold water judgment condition): When it is detected that the kettle is full of water and starts to boil water, the temperature of the side temperature sensing bag is detected to start boiling water. If it is hot (such as 30℃>t<80℃, the actual data is obtained according to the experiment), and the temperature changes within a period of time when the water starts to boil, such as a drop of 10℃ in 1 minute (calculation method: the temperature value detected after a period of time minus the temperature value before a period of time, the actual data is obtained according to the experiment) and it is a negative value (the reason is that cold water is added to the hot kettle in the hot state, and the cold water temperature is transferred to the kettle body and then to the side of the base, and the temperature will drop in the early stage of boiling water). It is considered that the hot kettle is boiling cold water. Within a period of time before the boiling work starts (such as within 2 minutes), if the weight change is detected to meet the evaporation judgment condition, it is considered to be a false boiling phenomenon, and it is not judged as boiling. Continue heating. After a period of time (such as 2 minutes), the evaporation boiling condition is judged again.

[0154] Case 4 (condition for judging whether the kettle is hot): When it is detected that the kettle is full of water and starts to boil water, the temperature of the side temperature sensing bag is detected. If it is hot (such as 30℃>t<80℃, the actual data is obtained according to experiments), the temperature change within a period of time after the water starts to boil water is detected. For example, the temperature change in 1 minute is not large, and the fluctuation is only 2-3℃ (calculation method: the temperature value detected after a period of time minus the temperature value before a period of time, the actual data is obtained according to experiments). It is considered that the kettle is boiling water. If the evaporation amount is detected to meet the boiling condition during the whole process of boiling water, it is judged that the water has boiled, and the heating state is exited and the insulation state is entered.

[0155] During the water boiling process, if the temperature of the side temperature sensor package rises too quickly or too high within a period of time, such as a temperature rise of more than 10°C in 1 minute or a temperature rise of more than 100°C (the actual data can be obtained from experiments), the system will consider the temperature rise abnormal, initiate an alarm, and terminate heating.

[0156] In this embodiment, the temperature of the temperature sensor is monitored in real time when boiling water in the kettle to make intelligent judgments on different boiling states, and different boiling process judgments are made according to the boiling states, thereby filtering out false boiling phenomena, accurately judging the boiling state, improving product performance and the accuracy and reliability of operation detection, and enhancing user experience.
