Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a method for determining the working state of a heating wire, a heating device, and a storage medium. Background Technology

[0002] A toaster is an electric cooking appliance specifically designed for re-baking sliced ​​bread. With the continuous improvement of people's living standards, toasters are widely used in many households. Currently, most toasters heat bread using internal heating wires. To ensure the normal operation of the toaster, it is essential to regularly check the temperature of the toaster walls to determine if the heating wires are functioning properly.

[0003] In related technologies, temperature sensors (such as NTC temperature sensors) are usually installed on the outer wall of the toaster to detect the temperature of the outer wall. However, due to the delay in temperature conduction, there is no good correspondence between the outer wall of the toaster and the inside of the toaster. It is easily affected by the surrounding environment and false detections may occur. That is, by detecting the temperature of the outer wall of the toaster, it is impossible to accurately infer the temperature inside the toaster, and thus accurately determine whether the heating wire inside the toaster is working properly. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] A toaster is an electric cooking appliance specifically designed for re-baking sliced ​​bread. With the continuous improvement of people's living standards, toasters have become widely used in many households. Currently, toasters generally heat bread using internal heating wires. To ensure the normal operation of a toaster, it is essential to regularly check the temperature of the toaster wall to determine if the heating wires are functioning properly. Therefore, a temperature sensor is usually installed on the outer wall of the toaster to detect its temperature. However, due to the delay in temperature conduction, there is no perfect correlation between the outer wall temperature and the internal temperature of the toaster. This makes it susceptible to environmental influences and false readings. In other words, detecting the temperature of the outer wall cannot accurately infer the internal temperature of the toaster, and thus cannot accurately determine the proper functioning of the heating wires.

[0028] In view of this, this application provides a method for determining the working state of a heating wire, applied to a heating device, which is equipped with a heating wire for heating an object, such as... Figure 1 As shown, the method includes:

[0029] Step 101: Collect the first temperature value of the heating equipment in its initial operating state.

[0030] Step 102: Determine the temperature status of the heating equipment based on the first temperature value.

[0031] Step 103: Collect the second temperature value of the heating equipment during the heating operation.

[0032] Step 104: Based on the temperature status of the heating equipment, collect the temperature value of the heating equipment after a preset time period following the end of the heating operation.

[0033] Step 105: Determine the working status of the heating wire based on the first temperature value, the second temperature value, and the temperature value after the preset time period following the end of the heating operation.

[0034] It should be noted that this application pre-installs temperature sensors on the outer wall of the heating device before determining the working status of the heating wire. Taking a toaster as an example, temperature sensors (such as NTC temperature sensors) can be installed on the outer walls of the two heating slots of the toaster. Based on this, all temperature values ​​collected in this application refer to the temperature values ​​of the outer wall of the heating device. The working status of the heating wire can be inferred from the collected temperature values ​​of the outer wall of the heating device.

[0035] In practical applications, when testing the heating wire of a heating device, the device may be in a cold state or a hot state. Determining its specific temperature state before testing the heating wire ensures more accurate results. Therefore, this application first collects the initial temperature value of the heating device in its initial operating state. This initial operating state refers to the current state of the heating device at the time of temperature acquisition; it can be a state where heating is not in progress, a state where heating has just been completed, or a state that has been completed for some time.

[0036] After determining the first temperature value corresponding to the initial operating state, the temperature state of the heating equipment can be determined based on this first temperature value. The specific method for determining the temperature state of the heating equipment is as follows: if the first temperature value is greater than a first preset temperature value, the heating equipment is determined to be in a hot-running state; if the first temperature value is less than or equal to the first preset temperature value, the heating equipment is determined to be in a cold-running state. The first preset temperature value can be determined based on the actual environmental conditions. For example, assuming the first preset temperature value is 40℃, then if the first temperature value is greater than 40℃, the heating equipment is determined to be in a hot-running state; and if the first temperature value is less than or equal to 40℃, the heating equipment is determined to be in a cold-running state.

[0037] If the heating equipment is determined to be in a cold state, the heating equipment is controlled to start heating, and a second temperature value is collected during the heating process. If the heating equipment is determined to be in a hot state, it indicates that the heating equipment is heating, and the second temperature value during the heating process can be directly collected. In this process, to better understand the temperature changes of the heating equipment during the heating process and to subsequently determine whether the heating wire is working properly, this second temperature value can preferably be the minimum temperature of the heating equipment during the heating process.

[0038] After acquiring the second temperature value of the heating equipment during the heating operation, the temperature value of the heating equipment after a preset time period following the end of the heating operation can be acquired based on the temperature state of the heating equipment. Specifically, if the heating equipment is in a hot-running state, the third temperature value is acquired after a first preset time period following the end of the heating operation. If the heating equipment is in a cold-running state, the third temperature value is acquired after a first preset time period following the end of the heating operation, and a fourth temperature value is acquired after a second preset time period following the end of the heating operation, where the second preset time period is longer than the first preset time period. It should be understood that different temperature states of the heating equipment will have different impacts on the subsequent judgment of the working state of the heating wire. Therefore, this application can effectively improve the accuracy of subsequent judgment of the working state of the heating wire by acquiring different temperature values ​​for different temperature states. The first and second preset time periods can be determined according to the actual working environment. For example, the first preset time period can be 40 seconds, and the second preset time period can be 70 seconds. No specific limitation is made here, as long as the second preset time period is longer than the first preset time period.

[0039] In practical applications, taking a first preset duration of 40 seconds and a second preset duration of 70 seconds as an example, if the device is in a hot-running state, the third temperature value is collected 40 seconds after the heating operation ends. If the device is in a cold-running state, the third temperature value is collected 40 seconds after the heating operation ends, and the fourth temperature value is collected 70 seconds after the heating operation ends. It should be noted that data within 40 seconds of the heating operation ending is not considered valuable due to the short detection time.

[0040] Finally, based on the first temperature value, the second temperature value, and the temperature value after a preset time period following the end of the heating operation, the working state of the heating wire can be determined. It should be noted that the method for determining the working state of the heating wire differs depending on whether the heating equipment is initially in a cold state or a hot state; details can be found in the embodiments below.

[0041] The heating wire working state determination method provided in this application collects a first temperature value of the heating device in its initial operating state and determines the temperature state of the heating device based on the first temperature value. This takes into account the influence of the heating device's temperature state on determining the heating wire state, thus improving the accuracy of subsequent determinations of the heating wire's working state. Furthermore, by collecting a second temperature value of the heating device during the heating operation and, based on the heating device's temperature state, collecting a temperature value of the heating device after a preset time period following the end of the heating operation, and then determining the heating wire's working state based on the first temperature value, the second temperature value, and the temperature value after the preset time period following the end of the heating operation, this method fully considers the delay in temperature conduction and the temperature values ​​of the heating device under different operating states. This ensures good correspondence between the outer wall and the interior of the heating device, avoiding false detections.

[0042] When determining the working state of the heating wire based on the first temperature value, the second temperature value, and the temperature value after a preset time period following the end of the heating operation:

[0043] As a first implementation: When the heating equipment is in a cold state, the working state of the heating wire is determined based on a first temperature value, a second temperature value, and the temperature value after a preset time period following the end of the heating operation. This includes: if, after a second preset time period following the end of the heating operation, the temperature rise of the heating equipment meets a preset low temperature rise condition based on the second and fourth temperature values, then the heating wire is determined to be in a fault state. It should be understood that when the heating equipment is in a cold state, a significant temperature rise should normally occur. If the temperature rise of the heating equipment meets the preset low temperature rise condition, it indicates that the temperature rise is small, which is inconsistent with normal conditions. Therefore, it can be determined that the heating wire is in a fault state (e.g., the heating wire has broken). This method can accurately determine the working state of the heating wire when the heating equipment is initially in a cold state, with high accuracy.

[0044] Specifically, determining whether the heating device's temperature rise meets the preset low temperature rise condition based on the second and fourth temperature values ​​includes: determining a first difference between the fourth and second temperature values; if the first difference is less than a first preset value, then the heating device's temperature rise meets the preset low temperature rise condition. The first preset value can be determined based on practical experience; for example, it can be 2, 3, 4, or 5. In this embodiment, the first difference is preferably 2. If the first difference is greater than or equal to the first preset value, it indicates that the heating wire is functioning normally, and the detection can be stopped.

[0045] As a second implementation: the working state of the heating wire is determined based on a first temperature value, a second temperature value, and the temperature value after a preset time period following the end of the heating operation. This includes: if the heating equipment is in a cold state or a hot state, and after the first preset time period following the end of the heating operation, the working state of the heating wire is determined based on the first temperature value, the second temperature value, and a third temperature value. It should be noted that in the cold state, if the preset time period following the end of the heating operation is greater than or equal to the first preset time period and less than or equal to the second preset time period, the determination method can be consistent with the determination method for the hot state. It should be understood that the temperature value after the preset time period following the end of the heating operation is considered here. Even if the initial working state of the heating equipment is a cold state, it will become a hot state after the heating operation ends. Therefore, this application considers both the cold and hot states comprehensively.

[0046] In practical applications, for example, when the heating equipment is in a cold state, assuming the first preset time period is 40 seconds and the second preset time period is 70 seconds, then when the preset time period after the heating operation ends is greater than or equal to 40 seconds and less than or equal to 70 seconds, the working state of the heating wire can be determined based on the first temperature value, the second temperature value, and the third temperature value. Similarly, when the heating equipment is in a hot state, when the preset time period after the heating operation ends is greater than or equal to 40 seconds, the working state of the heating wire can also be determined based on the first temperature value, the second temperature value, and the third temperature value.

[0047] In one optional embodiment, determining the operating state of the heating wire based on a first temperature value, a second temperature value, and a third temperature value includes: if the heating device's temperature rise meets a preset low temperature rise condition based on the first, second, and third temperature values, and the third temperature value is less than a second preset temperature value, then the heating wire is determined to be in a fault state. The second preset temperature value can be determined empirically; in this embodiment, the second preset temperature value is preferably 50°C.

[0048] It should be noted that when the heating equipment is in a hot-engine state, the temperature changes are quite complex and require careful differentiation and judgment. Specifically:

[0049] Figure 2 This is a schematic diagram showing the heating equipment continuously increasing in temperature over a preset time period. Figure 3 This is a schematic diagram showing that the temperature of the heating equipment first decreases and then increases within a preset time period. Figure 2 and Figure 3 The situation shown is generally normal, but there are exceptions. Taking a toaster as an example, if the heating equipment is in... Figure 2 and Figure 3In the scenario described, if the temperature rise of the heating equipment meets the preset low temperature rise condition, and the third temperature value is less than the second preset temperature value, it indicates that the heating wire in one heating slot of the toaster is normal, while the heating wire in the other heating slot is broken. The phrase "the temperature rise meets the preset low temperature rise condition, and the third temperature value is less than the second preset temperature value" corresponds to the temperature value collected from the outer wall of the heating slot where the heating wire is broken. Specifically, for example, when the temperature of the outer wall of the heating slot on one side of the toaster is measured, if the temperature rise does not exceed 3 degrees within a preset time period, and the highest temperature only reaches about 50°C, it indicates that the heating wire in that heating slot has broken.

[0050] When determining whether the heating range of the heating equipment meets the preset low heating condition, the following method can be used: if the first temperature value and the second temperature value are equal, and the second difference between the third temperature value and the second temperature value is less than the third preset temperature value, then the heating range of the heating equipment meets the preset low heating condition.

[0051] Figure 4 This diagram illustrates a heating device that first decreases in temperature and then maintains it, or where the temperature remains almost constant, within a preset time period. This typically occurs after the heating device has performed multiple heating operations. If the temperature of the heating device remains above 60°C under these conditions, the heating wire is functioning normally. Otherwise, further assessment is required.

[0052] Figure 5 This is a schematic diagram showing the temperature of the heating equipment continuously decreasing within a preset time period. Figure 5 The situation described typically occurs when the heating equipment is at a high temperature. The internal temperature of the heating equipment has decreased significantly, but the outer wall of the equipment remains at a relatively high temperature. This results in a rapid temperature drop and breakage during the heating process. However, this situation occurs at very high temperatures, generally above 85°C. (It should be noted that in the above...) Figures 2-5 In this diagram, the horizontal axis represents time, and the vertical axis represents temperature. In this case, the operating state of the heating wire is determined based on the first, second, and third temperature values, including:

[0053] Based on the second and third temperature values, it is determined whether the heating device's temperature rise meets the preset low temperature rise condition. If so, it is determined whether the heating device's temperature drop meets the preset high temperature drop condition based on the first and second temperature values, and whether the heating device meets the continuous temperature drop condition based on the second and third temperature values, and whether the third temperature value is greater than the fourth preset temperature value. If the preset high temperature drop condition is not met, or the continuous temperature drop condition is not met, or the third temperature value is less than or equal to the fourth preset temperature value, then the heating wire is determined to be in a faulty state. The fourth preset temperature value can be determined according to the actual operating environment; in this embodiment, the fourth preset temperature value is preferably 85°C.

[0054] In practical applications, a third difference between the first and second temperature values ​​can be determined first. If the third difference is greater than a second preset value, the cooling range of the heating equipment is determined to meet the preset high cooling condition. The second preset value can be determined based on the actual operating environment; for example, it can be 2, 3, 4, 5, etc. In this embodiment, the second preset value is preferably 3. Then, a fourth difference between the third and second temperature values ​​can be determined. If the fourth difference is greater than the third preset value, the heating equipment is determined to meet the continuous cooling condition. The third preset value can be determined based on the actual operating environment; for example, it can be -2, -3, -4, -5, etc. In this embodiment, the third preset value is preferably -2.

[0055] Specifically, as one implementation method, when the third difference between the first and second temperature values ​​is greater than 3, and the fourth difference between the third and second temperature values ​​is greater than -2, and the third temperature value is greater than 85°C, the heating wire is determined to be in a normal state. Conversely, when the third difference between the first and second temperature values ​​is less than or equal to 3, or the fourth difference between the third and second temperature values ​​is less than or equal to -2, or the third temperature value is less than or equal to 85°C, the heating wire is determined to be in a fault state.

[0056] In this embodiment of the application, the acquisition of the above-mentioned temperature values ​​can be achieved through the temperature detection circuit in the temperature sensor, such as... Figure 6 As shown, the temperature detection circuit includes: a negative temperature coefficient thermistor NTC1, a first capacitor C1, a second capacitor C2, a first resistor R1, a second resistor R2, a diode D, and a terminal JP6, etc. Their connection relationships can be found in [reference needed]. Figure 6 This will not be described in detail here.

[0057] Figure 7 This is a specific embodiment of the heating wire operating state determination method provided in this application, such as... Figure 7 As shown, the method includes:

[0058] The heating device is initially tested, and a first temperature value T1 is collected. If the first temperature value T1 is less than or equal to a first preset temperature value (assuming 40℃), the heating device is determined to be in a cold state. At this time, the heating device is controlled to start heating, and a second temperature value T2 is collected during the heating process. After determining the second temperature value T2, a fourth temperature value T4 is collected after the heating operation ends for a second preset time (assuming 70s). If the first difference between the fourth temperature value T4 and the second temperature value T2 is less than the first preset value (assuming 2), the heating wire is determined to be in a fault state. If the first difference between the fourth temperature value T4 and the second temperature value T2 is greater than or equal to 2, the heating wire is determined to be in a normal state.

[0059] If the first temperature value T1 is greater than the first preset temperature value of 40℃, the heating equipment is determined to be in a hot-running state. A second temperature value T2 is collected during the heating process. After determining this second temperature value T2, a third temperature value T3 is collected after a first preset time (assuming 40 seconds) has elapsed since the end of the heating operation. It should be noted that data collection within 40 seconds of the end of the heating operation is too short and has no reference value, and can be ignored. However, when the heating equipment is in a cold-running state, if the time after the end of the heating operation is greater than or equal to 40 seconds and less than or equal to 70 seconds, the third temperature value T3 can also be collected after the first preset time (assuming 40 seconds) has elapsed since the end of the heating operation.

[0060] After obtaining the third temperature value T3, determine the fourth difference between the third temperature value T3 and the second temperature value T2. If the fourth difference is greater than the third preset value (assuming it is 2), then the heating wire is considered to be normal. If the fourth difference is less than or equal to the third preset value, it indicates that the temperature of the heating equipment has risen, but the rise is small, and further judgment is needed.

[0061] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is greater than the second temperature value T2, it indicates that the temperature of the heating equipment is currently in a state of first decreasing and then increasing. At this time, the heating wire may be in a normal state or in a fault state, and further judgment is required.

[0062] If the first temperature value T1 equals the second temperature value T2, and the second difference between the third temperature value T3 and the second temperature value T2 is less than the third preset temperature value (assumed to be 2), then the heating device's temperature rise meets the preset low temperature rise condition. In this case, if the third temperature value T3 is less than 50℃, then the heating wire is faulty. Conversely, if the first temperature value T1 is not equal to the second temperature value T2, or the second difference between the third temperature value T3 and the second temperature value T2 is greater than or equal to the third preset temperature value, or the third temperature value T3 is greater than or equal to 50℃, then the heating wire is normal.

[0063] If the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is less than or equal to the second temperature value T2, it indicates that the temperature of the heating equipment may have dropped, and further judgment is needed:

[0064] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is equal to the second temperature value T2, and the third temperature value T3 is greater than 60℃, it indicates that the temperature of the heating equipment first decreases and then remains stable or remains almost unchanged within the preset time period. In this case, the heating wire can be determined to be normal. Conversely, if the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is not equal to the second temperature value T2, and the third temperature value T3 is less than or equal to 60℃, then the judgment continues:

[0065] If the third difference between the first temperature value T1 and the second temperature value T3 is greater than the second preset value (assuming it is 3), then the cooling range of the heating equipment meets the preset high cooling condition. If the fourth difference between the third temperature value T3 and the second temperature value T2 is greater than the third preset value (assuming it is -2), then the heating equipment meets the continuous cooling condition. In this case, if the third temperature value T3 is greater than the fourth preset temperature value (assuming it is 85℃), it indicates that this situation occurs when the heating equipment is at a high temperature, the internal temperature of the heating equipment has decreased significantly, but the outer wall of the heating equipment still has a high temperature, and the heating wire is in normal condition. Conversely, if the third difference between the first temperature value T1 and the second temperature value T3 is less than or equal to the second preset value, or the fourth difference between the third temperature value T3 and the second temperature value T2 is less than or equal to the third preset value, or the third temperature value T3 is less than or equal to the fourth preset temperature value, then the heating wire is in a faulty state.

[0066] The following scenario examples illustrate this application:

[0067] Application Scenario Example 1:

[0068] Assume the first preset duration is 40 seconds and the second preset duration is 70 seconds. Collect the second temperature value T2 of the heating device during the heating operation.

[0069] The initial temperature value corresponds to a cold state for the heating equipment, and the heating equipment remains cold for more than 70 seconds after the heating operation ends. At this point, the fourth temperature value T4 is collected 70 seconds after the heating operation ends. If the first difference between the fourth temperature value T4 and the second temperature value T2 is less than a first preset value (assumed to be 2), the heating wire is determined to be in a faulty state. If the first difference between the fourth temperature value T4 and the second temperature value T2 is greater than or equal to 2, the heating wire is determined to be in a normal state.

[0070] Application Scenario Example 2:

[0071] Assume the first preset duration is 40 seconds and the second preset duration is 70 seconds. Collect the first temperature value T1 of the heating device in its initial operating state and the second temperature value T2 of the heating device during the heating process. The first temperature value in the initial operating state corresponds to the heating device being in a cold state, and the heating device's temperature after the heating operation ends is between 40 seconds and 70 seconds.

[0072] The third temperature value T3 is collected 40 seconds after the heating operation ends. It should be noted that data collected within 40 seconds of the heating operation ending is too short to be of significant value and can be ignored. However, if the heating equipment is in a cold state, and the time since the heating operation ended is greater than or equal to 40 seconds and less than or equal to 70 seconds, the third temperature value T3 can also be collected 40 seconds after the first preset heating duration ends.

[0073] After obtaining the third temperature value T3, determine the fourth difference between the third temperature value T3 and the second temperature value T2. If the fourth difference is greater than the third preset value (assuming it is 2), then the heating wire is considered to be normal. If the fourth difference is less than or equal to the third preset value, it indicates that the temperature of the heating equipment has risen, but the rise is small, and further judgment is needed.

[0074] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is greater than the second temperature value T2, it indicates that the temperature of the heating equipment is currently in a state of first decreasing and then increasing. At this time, the heating wire may be in a normal state or in a fault state, and further judgment is required.

[0075] If the first temperature value T1 equals the second temperature value T2, and the second difference between the third temperature value T3 and the second temperature value T2 is less than the third preset temperature value (assumed to be 2), then the heating device's temperature rise meets the preset low temperature rise condition. In this case, if the third temperature value T3 is less than 50℃, then the heating wire is faulty. Conversely, if the first temperature value T1 is not equal to the second temperature value T2, or the second difference between the third temperature value T3 and the second temperature value T2 is greater than or equal to the third preset temperature value, or the third temperature value T3 is greater than or equal to 50℃, then the heating wire is normal.

[0076] If the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is less than or equal to the second temperature value T2, it indicates that the temperature of the heating equipment may have dropped, and further judgment is needed:

[0077] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is equal to the second temperature value T2, and the third temperature value T3 is greater than 60℃, it indicates that the temperature of the heating equipment first decreases and then remains stable or remains almost unchanged within the preset time period. In this case, the heating wire can be determined to be normal. Conversely, if the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is not equal to the second temperature value T2, and the third temperature value T3 is less than or equal to 60℃, then the judgment continues:

[0078] If the third difference between the first temperature value T1 and the second temperature value T3 is greater than the second preset value (assuming it is 3), then the cooling range of the heating equipment meets the preset high cooling condition. If the fourth difference between the third temperature value T3 and the second temperature value T2 is greater than the third preset value (assuming it is -2), then the heating equipment meets the continuous cooling condition. In this case, if the third temperature value T3 is greater than the fourth preset temperature value (assuming it is 85℃), it indicates that this situation occurs when the heating equipment is at a high temperature, the internal temperature of the heating equipment has decreased significantly, but the outer wall of the heating equipment still has a high temperature, and the heating wire is in normal condition. Conversely, if the third difference between the first temperature value T1 and the second temperature value T3 is less than or equal to the second preset value, or the fourth difference between the third temperature value T3 and the second temperature value T2 is less than or equal to the third preset value, or the third temperature value T3 is less than or equal to the fourth preset temperature value, then the heating wire is in a faulty state.

[0079] Application Scenario Example 3:

[0080] Assume the first preset duration is 40 seconds and the second preset duration is 70 seconds. Collect the first temperature value T1 of the heating device in its initial operating state and the second temperature value T2 of the heating device during the heating process. The temperature state of the heating device corresponding to the first temperature value in the initial operating state is the hot-engine state, and the time after the heating operation ends is greater than or equal to 40 seconds.

[0081] The third temperature value T3 of the heating equipment is collected 40 seconds after the heating operation ends. It should be noted that data collected within 40 seconds of the heating operation ending is too short to be of reference value and can be ignored. However, if the heating equipment is in a cold state, and the time since the heating operation ended is greater than or equal to 40 seconds and less than or equal to 70 seconds, the third temperature value T3 of the heating equipment 40 seconds after the heating operation ends can also be collected.

[0082] After obtaining the third temperature value T3, determine the fourth difference between the third temperature value T3 and the second temperature value T2. If the fourth difference is greater than the third preset value (assuming it is 2), then the heating wire is considered to be normal. If the fourth difference is less than or equal to the third preset value, it indicates that the temperature of the heating equipment has risen, but the rise is small, and further judgment is needed.

[0083] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is greater than the second temperature value T2, it indicates that the temperature of the heating equipment is currently in a state of first decreasing and then increasing. At this time, the heating wire may be in a normal state or in a fault state, and further judgment is required.

[0084] If the first temperature value T1 equals the second temperature value T2, and the second difference between the third temperature value T3 and the second temperature value T2 is less than the third preset temperature value (assumed to be 2), then the heating device's temperature rise meets the preset low temperature rise condition. In this case, if the third temperature value T3 is less than 50℃, then the heating wire is faulty. Conversely, if the first temperature value T1 is not equal to the second temperature value T2, or the second difference between the third temperature value T3 and the second temperature value T2 is greater than or equal to the third preset temperature value, or the third temperature value T3 is greater than or equal to 50℃, then the heating wire is normal.

[0085] If the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is less than or equal to the second temperature value T2, it indicates that the temperature of the heating equipment may have dropped, and further judgment is needed:

[0086] If the first temperature value T1 is greater than or equal to the second temperature value T2, and the third temperature value T3 is equal to the second temperature value T2, and the third temperature value T3 is greater than 60℃, it indicates that the temperature of the heating equipment first decreases and then remains stable or remains almost unchanged within the preset time period. In this case, the heating wire can be determined to be normal. Conversely, if the first temperature value T1 is less than the second temperature value T2, or the third temperature value T3 is not equal to the second temperature value T2, and the third temperature value T3 is less than or equal to 60℃, then the judgment continues:

[0087] If the third difference between the first temperature value T1 and the second temperature value T3 is greater than the second preset value (assuming it is 3), then the cooling range of the heating equipment meets the preset high cooling condition. If the fourth difference between the third temperature value T3 and the second temperature value T2 is greater than the third preset value (assuming it is -2), then the heating equipment meets the continuous cooling condition. In this case, if the third temperature value T3 is greater than the fourth preset temperature value (assuming it is 85℃), it indicates that this situation occurs when the heating equipment is at a high temperature, the internal temperature of the heating equipment has decreased significantly, but the outer wall of the heating equipment still has a high temperature, and the heating wire is in normal condition. Conversely, if the third difference between the first temperature value T1 and the second temperature value T3 is less than or equal to the second preset value, or the fourth difference between the third temperature value T3 and the second temperature value T2 is less than or equal to the third preset value, or the third temperature value T3 is less than or equal to the fourth preset temperature value, then the heating wire is in a faulty state.

[0088] In summary, this application embodiment improves the accuracy of determining the heating wire's working state by collecting a first temperature value of the heating device in its initial operating state and determining the temperature state of the heating device based on the first temperature value. It also considers the influence of the heating device's temperature state on determining the heating wire's working state. By collecting a second temperature value of the heating device during the heating operation and, based on the heating device's temperature state, collecting the temperature value of the heating device after a preset time period following the end of the heating operation, and then determining the heating wire's working state based on the first temperature value, the second temperature value, and the temperature value after the preset time period following the end of the heating operation, the application fully considers the delay in temperature conduction and the temperature values ​​of the heating device in different operating states, ensuring good correspondence between the outer wall and the interior of the heating device and avoiding false detections. Furthermore, it should be noted that by collecting the temperature value of the heating device in its initial operating state, the minimum temperature value during the heating operation, and the temperature value 40 seconds or 70 seconds after the operation ends, this application can accurately grasp the temperature changes of the heating device during the heating operation, ensuring the accuracy of subsequent determination of the heating wire's working state.
