[0002] With the development of smart kitchen appliances, some gas stoves are equipped with anti-dry-burning protection functions to automatically cut off the gas supply when the pot is dry-burned or when there is no water for an extended period of time at high temperatures, preventing fires and other safety accidents. Currently, anti-dry-burning protection mostly relies on temperature sensors to detect the temperature of the pot bottom and trigger the protection action when a set threshold is reached. However, in actual use, due to sensor drift, control logic defects, or actuator failure, the anti-dry-burning function may fail to activate properly, posing a safety hazard. Therefore, it is necessary to test the anti-dry-burning protection function of the stove. Summary of the Invention

[0005] According to the cooktop anti-dry-burning test method of this application, the range hood is linked to operate in a preset working mode when the target cooktop is heating, simulating a real cooking environment. A first preset duration is dynamically set based on the preset working mode, so that the high temperature duration of the target cooktop is matched with the actual heat dissipation conditions, improving the accuracy of fault identification. If the current pot bottom temperature continuously exceeds the target anti-dry-burning temperature threshold and exceeds the first preset duration after adaptation, and the target cooktop still does not trigger the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target cooktop has a first fault. This can realize intelligent detection of the failure of the anti-dry-burning protection function of the target cooktop, improving the safety and reliability of cooktop use.

[0006] According to one embodiment of this application, after obtaining the current pot bottom temperature of the target stove, the method further includes: If the current pot bottom temperature is lower than the target anti-dry-burning temperature threshold and the target stove triggers anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a second fault.

The first preset duration is dynamically set based on the preset working mode, so that the high temperature duration of the target cooktop is matched with the actual heat dissipation conditions, which improves the accuracy of fault identification. If the current pot bottom temperature continuously exceeds the target anti-dry-burning temperature threshold and exceeds the first preset duration after adaptation, and the target cooktop still does not trigger the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target cooktop has a first fault.

[0022] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which: Figure 1 This is a flowchart illustrating the stove anti-dry-burning test method provided in the embodiments of this application; Figure 2 This is a schematic diagram of the stove anti-dry-burning testing device provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the electronic device provided in the embodiments of this application. Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The following description, in conjunction with the accompanying drawings, details the stove anti-dry-burning test method, stove anti-dry-burning test device, stove, stove anti-dry-burning test system, electronic device, and readable storage medium provided in this application through specific embodiments and application scenarios.

[0026] The method for testing the anti-dry burning of stoves can be applied to terminals, and can be executed by the hardware or software in the terminal.

[0027] The stove anti-dry-burning test method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can realize the stove anti-dry-burning test method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras and wearable devices. The stove anti-dry-burning test method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0028] The stove provided in this application embodiment has a dry-burn protection function. The dry-burn protection function is that when the cookware on the stove is detected to be dry-burning, the stove will automatically shut off to avoid the safety hazards caused by the cookware being dry-burning for too long.

[0029] The cooktop anti-dry-burning test method provided in this application embodiment is used to test the cooktop's anti-dry-burning protection function in a scenario where the range hood above the cooktop is turned on and running.

[0030] like Figure 1 As shown, the method for testing the stove's anti-dry burning capability includes steps 110, 120, and 130.

[0031] Step 110: When the target stove is in the heating state, control the range hood above the target stove to turn on and operate according to the preset working mode.

[0032] The target stove is the stove whose anti-dry-burning protection function is to be tested. The preset working mode is a combination of pre-set operating parameters of the range hood, such as fan speed and running time.

[0033] In this step, a pot is placed on the pot rack of the target stove, the target stove is lit, and the range hood above the target stove is turned on and controlled to operate according to the preset working mode to provide the corresponding test environment.

[0034] Step 120: Obtain the current bottom temperature of the target stove.

[0035] The current pot bottom temperature refers to the temperature of the bottom of the pot at the current moment.

[0036] A temperature sensor can be installed at the bottom contact point of the pot on the stove to detect the current bottom temperature of the pot in real time.

[0037] Step 130: If the current pot bottom temperature continues to exceed the target anti-dry-burning temperature threshold of the target stove for more than a first preset time, and the target stove does not trigger the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a first fault.

[0038] Among them, the target anti-dry burning temperature threshold is the upper limit of the temperature that the pot placed on the stove can withstand when the stove is working. The first preset time is determined based on the preset working mode. The first preset time can be dynamically adjusted according to the suction strength and heat exhaust efficiency corresponding to the preset working mode of the range hood. For example, a longer first preset time can be set in the strong suction mode, and a shorter first preset time can be set in the low speed or standby mode.

[0039] It should be noted that turning on the range hood in step 110 is the most common scenario for cooking or timed cooking on the target stove. When the range hood is set to different fan speeds, it will affect the airflow pattern below it, especially around the stove, increasing the local wind speed on the sides and above the stove. The testing method aims to detect any malfunctions in the anti-dry-burning mechanism under such environmental disturbances.

[0040] In this embodiment, when the current pot bottom temperature is detected to be continuously greater than the target anti-dry-burning temperature threshold and the duration exceeds the first preset duration, it indicates that the pot may be dry-burning and the anti-dry-burning protection function of the stove needs to be triggered. However, if the anti-dry-burning protection is not triggered at this time, it can be determined that the anti-dry-burning protection function of the target stove has a first fault. The first fault is that the protection action such as automatic flameout or power reduction is not triggered as expected, that is, the anti-dry-burning function fails.

[0041] According to the stove anti-dry-burning test method provided in the embodiments of this application, the range hood is linked to operate in a preset working mode when the target stove is heating, simulating a real cooking environment. A first preset duration is dynamically set based on the preset working mode, so that the high temperature duration of the target stove is matched with the actual heat dissipation conditions, improving the accuracy of fault identification. If the current pot bottom temperature continuously exceeds the target anti-dry-burning temperature threshold and exceeds the first preset duration after adaptation, and the target stove still does not trigger the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a first fault. This can realize intelligent detection of the failure of the anti-dry-burning protection function of the target stove, improving the safety and reliability of stove use.

[0042] In some embodiments, after obtaining the current bottom temperature of the target stove, the method further includes: If the current pot bottom temperature is lower than the target anti-dry-burning temperature threshold, and the target stove triggers the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a second fault.

[0043] In this embodiment, the current pot bottom temperature being lower than the target anti-dry-burning temperature threshold indicates that the target stove is heating the pot normally and the pot is not dry-burning. The anti-dry-burning protection function of the target stove should not be triggered. However, the target stove triggers the anti-dry-burning protection at this time, which indicates that the anti-dry-burning protection function of the target stove has a second fault. The second fault is that the anti-dry-burning protection function is mistakenly triggered when the pot is not dry-burning, that is, the anti-dry-burning protection function malfunctions.

[0044] In some embodiments, the preset operating mode includes the range hood cycling between its various speed settings and operating at each speed setting for a second preset duration.

[0045] The second preset duration can be a preset duration.

[0046] In this embodiment, the range hood may include multiple operating levels, such as low, medium and high. The range hood can cycle between low, medium and high levels, and operate for a second preset duration at each level.

[0047] In this embodiment, when the preset working mode is that the range hood is running in a cycle between different speeds, the first preset duration can be calculated by weighting the average exhaust volume or equivalent heat dissipation capacity of a complete cycle. For example, the second preset duration corresponding to each speed is multiplied by its wind speed weight and then summed. A reasonable first preset duration is set based on the summation result.

[0048] In some embodiments, the first preset duration is determined by the following steps: The first preset sub-duration is determined based on the preset working mode, and the second preset sub-duration is determined based on the cooking status of the target stove. The first preset duration is determined based on the first preset sub-duration and the second preset sub-duration.

[0049] Among them, the cooking state is used to characterize whether water vapor is generated during the cooking process of the target stove, that is, whether water is involved in the cooking process.

[0050] In this embodiment, the first preset sub-duration is first determined according to the preset working mode, reflecting the influence of the range hood's smoke exhaust capacity on heat dissipation; then, the second preset sub-duration is determined in combination with whether water vapor is generated during the cooking state of the target stove; finally, the first preset sub-duration and the second preset sub-duration are combined by weighting or taking the minimum value to determine the final first preset duration.

[0051] In some embodiments, the cooking state includes a water-cooking state, a waterless cooking state, and a mixed cooking state, wherein the mixed cooking state includes a water-cooking stage and a waterless cooking stage, and determining a second preset sub-duration based on the cooking state of the target stove includes: When the cooking state is water-cooked, the second preset sub-duration is determined to be the first duration; When the cooking state is waterless cooking state, the second preset sub-duration is determined as the second duration; When the cooking state is mixed cooking state, the second preset sub-duration is determined as the third duration; The first duration is longer than the third duration, and the third duration is longer than the second duration.

[0052] Cooking with water can include steaming buns, boiled eggs, steaming fish, etc., which corresponds to high heat; boiling noodles, mung bean porridge, etc., which corresponds to a 50% high heat and 50% medium heat; stewing pork rib soup, chicken soup, etc., which corresponds to a simmer after boiling on high heat. The pots used are iron pots for steaming, stainless steel pots for boiling, and earthenware pots for stewing.

[0053] Waterless cooking can include stir-frying chili peppers and meat, stir-frying vegetables, etc., which correspond to high heat; stir-frying peanuts, etc., which correspond to low heat; frying eggs, steak, etc., which correspond to medium heat (30%) and low heat (70%); and frying popcorn chicken and chicken cutlets, etc., which correspond to high heat to boil and then low heat. The cookware used is an iron pot for stir-frying, a stainless steel pot for frying, and an aluminum alloy pot for deep-frying.

[0054] Mixed cooking methods can include frying first and then boiling, such as making cola chicken wings, which corresponds to 40% frying over medium heat and 60% boiling over high heat; or stir-frying first and then stewing, such as stewing pork ribs with potatoes, which corresponds to stir-frying over high heat and then stewing over medium heat. The cookware used includes using an iron pot when frying first and then boiling, and using a stainless steel pot when stir-frying first and then stewing.

[0055] In this embodiment, when cooking with water, a longer first cooking time is set because water vapor can cool the food and delay dry burning; when cooking without water, heat dissipates quickly and is prone to rapid dry burning, so a shorter second cooking time is set; and when cooking in a mixed manner, which involves two stages and has a risk between the two, a moderate third cooking time is set.

[0056] By dynamically selecting the first, third, or second time period as the second preset sub-time period based on the cooking status, the actual thermal risks can be matched more accurately, ensuring the reliability and safety of the anti-dry burning fault judgment.

[0057] In some embodiments, the method for testing the dry-burning resistance of cooktops further includes: If the target stove is in the heating state, the pot is removed from the target stove, and the target stove triggers the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a third fault.

[0058] In this embodiment, a cookware detection device, such as a weight sensor, can be installed on the pot rack of the target stove. The cookware detection device detects whether a pot is placed on the target stove. When the target stove is in the heating state, if the removal of the pot is detected, i.e., the pot is removed from the target stove, the anti-dry-burning protection function should not be triggered since there is no pot on the target stove. However, if the anti-dry-burning protection is triggered at this time, it can be determined that the anti-dry-burning protection function of the target stove has a third fault. The third fault is a malfunction caused by incorrect perception or logical defects.

[0059] In some embodiments, the method for testing the dry-burning resistance of cooktops further includes: If the target stove is in a heating state and the cookware it is in contact with changes within a third preset time period, and the target stove triggers the anti-dry-burning protection, then the anti-dry-burning protection function of the target stove is determined to have a fourth fault.

[0060] The third preset duration is a preset duration, which starts counting from when the new pot is placed on the target stove.

[0061] In this embodiment, when the target stove is in a heating state and the pot on the target stove is replaced, within the third preset time period when the new pot is placed on the target stove, the new pot is still in a low temperature state and should not trigger the anti-dry-burning protection function. However, the anti-dry-burning protection is triggered at this time, which can be determined that the anti-dry-burning protection function of the target stove has a fourth fault. The fourth fault is an improper response to the temperature change during the pot replacement process and is a malfunction caused by misjudgment.

[0062] The following is a specific implementation method for testing the anti-dry-burning properties of a stove.

[0063] In this embodiment, the cooktop anti-dry-burning test method is performed by a control device connected to the range hood and the cooktop.

[0064] The control device includes a range hood detection module and a range hood control module. The range hood control module can control the range hood to operate at low, medium, high and stir-fry settings, and has a timer to time the operation time of the range hood at each setting.

[0065] The control device can also read the temperature of the bottom of the pot on the stove, and can time the process. It can also read the firepower value of the stove, determine whether the stove is on high, medium or low fire, and identify the status of the stove at the current moment.

[0066] The control device can also perform temperature testing, read the internal temperature of the cookware, attach the temperature sensor to the bottom of the inside of the cookware, and record the cookware as dry-burning when the temperature continuously exceeds 103°C.

[0067] The detection head is close to the bottom of the pot and detects the temperature (1) the highest protection temperature point: 350℃, lasting for 3 seconds, triggering the anti-dry burning protection; (2) the second highest protection temperature point: 320℃, lasting for 10 seconds, triggering the anti-dry burning protection, and can record the current pot as dry burning; (3) the stable stage temperature is less than 180℃, and the break point temperature is 270℃.

[0068] If a dry-burning state persists for more than t1 minutes (low heat), t2 minutes (medium heat), or t3 minutes (high heat) without triggering a dry-burning alarm, the dry-burning protection function is considered faulty. The recognition rate across multiple tests is then calculated. Here, t1 can be 9 minutes, t2 can be 7 minutes, and t3 can be 5 minutes. For example, if a dry-burning state persists for more than 5 minutes (high heat) without triggering a dry-burning alarm, the function is considered to have failed. The recognition rate across multiple tests is then calculated.

[0069] It also provides the highest temperature at the bottom of the pot under the current fault condition, any sudden changes, and the temperature change gradient, so that relevant personnel can identify the problem.

[0070] In this embodiment, the overall dry-burn protection success rate of the stove can be obtained based on multiple tests. When the success rate is less than a set value, such as less than 95%, it can be determined that there may be a problem with the stove's hardware, sensor drift, or software logic writing error.

[0071] The following is a specific embodiment of another method for testing the anti-dry burning properties of stoves.

[0072] In this embodiment, the cooktop anti-dry-burning test method is performed by a control device connected to the range hood and the cooktop.

[0073] The control device includes a range hood detection module and a range hood control module. The range hood control module can control the range hood to operate at low, medium, high and stir-fry settings, and has a timer to time the operation time of the range hood at each setting.

[0074] The control device can also read the temperature of the bottom of the pot on the stove, and can time the process. It can also read the firepower value of the stove, determine whether the stove is on high, medium or low fire, and identify the status of the stove at the current moment.

[0075] The control device can also perform temperature testing, reading the internal temperature of the pot. The temperature detection head is attached to the bottom of the pot's interior. When the temperature remains at the highest protection temperature (350℃) for 3 seconds, the anti-dry-burning protection is triggered; when it remains at the second highest protection temperature (320℃) for 10 seconds, the anti-dry-burning protection is triggered. The device can record the current state of the pot being dry-burned. During the stable phase, the temperature is below 180℃, and the breakpoint temperature is 270℃. If the dry-burning state persists for more than 5 minutes (5 minutes on high heat) without triggering the dry-burning alarm, it is considered a fault, and the recognition rate of multiple tests is statistically analyzed.

[0076] It also provides the highest temperature at the bottom of the pot under the current fault condition, any sudden changes, and the temperature change gradient, so that relevant personnel can identify the problem.

[0077] Below are some specific implementation examples of methods for testing the anti-dry-burning properties of stoves.

[0078] Range hood anti-interference test: Under the set pressure, the test lasted for six hours. 3L of water was placed in the pot of the target stove and heated over medium to high heat. The pot could be a cast iron pot, aluminum alloy pot, or stainless steel pot with a pointed or flat bottom. The range hood was turned on at low, medium, high, and stir-fry settings, switching between each setting every 3 minutes. 1. After the pot was dry-burned, the timer was started immediately after the water in the pot was visually extinguished. The protection should be triggered within 3 minutes. The dry-burn protection should not be triggered during the boiling process. The timer was started immediately after the pot was dry-burned and the anti-dry-burn protection should be triggered within 3 minutes.

[0079] Cookware replacement test: Under set pressure, test for four hours. Put 1L of water in the pot and heat it over high heat. After the water boils, remove the pot. Keep the stove heat unchanged. Immediately after 30 seconds, replace it with a cold pot of another material (such as a pointed or flat-bottomed iron pot, aluminum alloy pot, or stainless steel pot). Within 30 seconds of replacing the pot, the dry-burn protection should not be triggered. The new cold pot should not trigger the dry-burn protection.

[0080] Dry-boiling test with an empty pot: Under set pressure conditions, test for two hours, dry-burn the cookware (which can be a pointed-bottom or flat-bottomed iron pot, aluminum alloy pot or stainless steel pot), without putting any liquid or food in the cookware, ignite the stove in a cold state, and keep the cookware burning at a high flame while it is cold (at room temperature), the stove should not trigger the dry-burn protection within 1 minute, and the stove should trigger the dry-burn protection between 1 minute and 3 minutes.

[0081] No pot, no heat: Under set pressure conditions, the stove is tested for one hour. The stove is ignited from a cold state and the flame continues to burn until the overheat protection device is activated. The stove should not trigger the dry-burn protection within 1 minute, and the stove should trigger the dry-burn protection between 1 minute and 3 minutes.

[0082] Boiling water dry: Under set pressure conditions, test for twelve hours by putting 1L of water in the pot (2L for a clay pot) and heating it over high heat (it can be a pointed or flat-bottomed iron pot, aluminum alloy pot or stainless steel pot) until the water in the pot boils dry and the overheat protection device is activated. Start timing immediately after the pot is dry-boiled. The dry-boil protection should be triggered within 3 minutes. The dry-boil protection should not be triggered during the boiling process.

[0083] Porridge cooking test: Under set pressure conditions, the test lasted for six hours. 1L of water and 200g of rice were placed in the pots respectively. After the water was brought to a boil over high heat, the heat was switched to low heat (for both the clay pot and the stainless steel pot). When the pots were dry-heated, the timer started when smoke began to appear inside the pot and a burnt smell was detected. The pots should automatically shut off within 3 minutes and the protection should not be triggered during the cooking process.

[0084] Cooking with water: The test lasted twelve hours. Cooking with water included steaming buns, boiled eggs, steaming fish, etc., corresponding to a high-heat scenario; boiling noodles, mung bean porridge, etc., corresponding to a scenario with 50% high heat and 50% medium heat; stewing pork rib soup, chicken soup, etc., corresponding to a scenario with high heat to boil and then low heat. The pots used were iron pots for steaming, stainless steel pots for boiling, and earthenware pots for stewing.

[0085] The stove should not trigger the protection mechanism while the water is still wet; once the water has dried, the stove should trigger the protection mechanism within 3 minutes.

The acquisition module 220 is used to acquire the current bottom temperature of the target stove. The second processing module 230 is used to determine that the anti-dry-burning protection function of the target stove has a first fault when the current pot bottom temperature is continuously higher than the target anti-dry-burning temperature threshold of the target stove for more than a first preset time and the target stove has not triggered the anti-dry-burning protection. The first preset time is determined based on the preset working mode.

The first preset duration is dynamically set based on the preset working mode, so that the high temperature duration of the target stove is matched with the actual heat dissipation conditions, improving the accuracy of fault identification. If the current pot bottom temperature continuously exceeds the target anti-dry-burning temperature threshold and exceeds the first preset duration after adaptation, and the target stove still does not trigger the anti-dry-burning protection, it is determined that the anti-dry-burning protection function of the target stove has a first fault.
