[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Currently, with the development of technology, infrared temperature detection modules are increasingly being used in heating equipment for temperature detection. Infrared temperature detection modules obtain the detected temperature by receiving infrared rays radiated by cooking utensils.

[0019] However, in some scenarios, obstructions affecting infrared light propagation can exist in heating devices. For example, oil stains on the heating panel or dust buildup on the infrared temperature detection module due to prolonged use can reduce the amount of infrared light received by the module, leading to a significant discrepancy between the detected temperature and the actual temperature of the cooking appliance. This can result in excessively long heating times, increasing the risk of dry burning or even fire, posing a significant safety hazard.

[0020] To address the aforementioned problems, the inventors have proposed a heating protection method, apparatus, heating device, and storage medium as described in this application. This method is used in heating devices equipped with an infrared temperature detection module and includes: acquiring a candidate temperature; determining a detection temperature based on the detection signal from the infrared temperature detection module; determining a temperature difference between the detection temperature and the candidate temperature; and determining the operating temperature based on the temperature difference. This application determines the operating temperature of the heating device based on the temperature difference between the candidate temperature and the detection temperature, thereby determining a smaller operating temperature for the current scenario based on the detection error of the infrared temperature detection module, thus ensuring the heating safety of the heating device and reducing the probability of accidents. The application environment of the heating protection method provided by this invention is described below.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a heating protection method provided in an embodiment of the present invention. The method is applied to a heating device 100, which includes a device body 140 and an infrared temperature detection module 110 disposed on the device body 140. The heating device 100 can heat a cooking appliance 200 placed on the device body 140. The infrared temperature detection module 110 can detect the temperature of the cooking appliance 200 to obtain a detection signal, and the detection temperature of the cooking appliance 200 can be determined based on the detection signal.

[0022] In some embodiments, the heating device 100 further includes a heating panel 120 disposed on the device body 140, on which the cooking utensil 200 can be placed. Optionally, the heating panel 120 may be made of glass, ceramic, or microcrystalline materials.

[0023] In some embodiments, the heating device 100 further includes a heating module 130 disposed on the device body 140. Optionally, the heating module 130 may be a heating coil.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that, under normal circumstances, the detected temperature can be used as the operating temperature of the heating device, that is, the temperature of the cooking appliance determined by the infrared temperature detection module. However, as explained above in the instruction manual, the detected temperature obtained by the infrared temperature detection module may have a large error in some scenarios. In such cases, the operating temperature can be re-determined based on the temperature difference between the detected temperature and the alternative temperature. This allows for the determination of a lower error in the current scenario based on the detection error of the infrared temperature detection module. When the detection error of the detected temperature is large, the heating device operates according to the re-determined operating temperature, thereby ensuring heating safety and reducing the probability of accidents. Furthermore, there are many alternative temperatures to choose from, but the alternative temperature must, like the detected temperature, reflect the actual temperature of the cooking appliance. Moreover, even if the detected temperature is abnormal, the alternative temperature must still be able to detect it normally, thus ensuring heating safety. It is understandable that, under normal circumstances, the alternative temperature may not be as accurate as the detected temperature. However, when the error of the detected temperature is large, the error of the alternative temperature is smaller than that of the detected temperature. In this case, the alternative temperature can also reflect the actual temperature of the cooking appliance, with a smaller error compared to using the detected temperature.

[0026] In some implementations, the alternative temperature can be the heating panel temperature, the ambient temperature of the heating device, or the cooking appliance temperature measured by a temperature sensor such as a thermistor.

[0027] It is understood that there can be many alternative temperatures, and this application does not impose any restrictions. However, for the sake of explanation, the heating panel temperature is used as an example of an alternative temperature in the embodiments of this application.

[0028] Please see Figure 2 , Figure 2 This is a schematic flowchart of a heating protection method provided in an embodiment of the present invention. Figure 2 As shown, this method is applied to heating equipment with an infrared temperature detection module, such as... Figure 1 The heating device 100 in the middle, the method includes: steps 210 to 240.

[0029] Step 210: Obtain alternative temperatures.

[0030] Specifically, in the embodiments of this application, the heating panel temperature is used as an example for illustration. For example, the heating panel is... Figure 1 The heating panel 120 is included; it is understood that this application is not limited thereto, and other types of alternative temperatures may be used in other embodiments.

[0031] In some implementations, the temperature of the heating panel can be obtained by detecting the temperature of the heating panel using an infrared temperature detection module.

[0032] In other embodiments, the temperature of the heating panel can be obtained by detecting the temperature of the heating panel using a temperature sensor such as a thermistor.

[0033] It is understood that other methods can be used to determine the temperature of the heating panel, and this application does not limit the method of determining the temperature of the heating panel.

[0034] Step 220: Determine the detection temperature based on the detection signal from the infrared temperature detection module.

[0035] In some implementations, the detection temperature can be determined based on the signal strength of the detected signal. For example, a table relating signal strength to detection temperature can be pre-set, allowing the detection temperature to be obtained by looking up the value in the table based on the detected signal strength.

[0036] In other implementations, the detection temperature can be determined by combining the reflectivity of the cooking appliance. For example, the properties of the cooking appliance itself, such as its material, can be determined based on the reflectivity, and the detection temperature can be obtained based on the properties of the cooking appliance itself and the signal strength of the detection signal.

[0037] It is understood that other methods can be used to determine the detection temperature, and this application does not limit the method of determining the detection temperature.

[0038] Furthermore, if an infrared temperature detection module is used to simultaneously detect the temperature of the heating panel and the cooking appliance, the infrared temperature detection module can determine the temperature of the heating panel by receiving long-wavelength infrared light and determine the temperature of the cooking appliance (i.e., the detected temperature) by receiving medium-wavelength infrared light. However, the medium-wavelength infrared light only reaches the infrared temperature detection module after passing through the heating panel. When there is oil on the heating panel or dust on the infrared temperature detection module due to long-term use, the amount of medium-wavelength infrared light received by the infrared temperature detection module will decrease, while the long-wavelength infrared light can still be received normally. Therefore, the detected temperature error is relatively large in this case, while the temperature of the heating panel is detected normally.

[0039] Step 230: Determine the temperature difference based on the detected temperature and the alternative temperature.

[0040] Specifically, when the infrared temperature detection module is working normally, the temperature difference between the detected temperature and the heating panel temperature is small. However, in certain scenarios, such as when there is oil on the heating panel or dust adhering to the infrared temperature detection module due to long-term use, the detection error of the infrared temperature detection module is larger, while the heating panel temperature is detected normally. In this case, the temperature difference between the detected temperature and the heating panel temperature is also larger. Therefore, by determining the temperature difference between the detected temperature and the candidate temperature, it is possible to determine whether the infrared temperature detection module is working normally.

[0041] In some implementations, the temperature difference between the detected temperature and the alternative temperature is the absolute value of (detected temperature minus alternative temperature).

[0042] Step 240: Determine the operating temperature based on the temperature difference.

[0043] Specifically, the operating temperature is the temperature upon which the temperature control logic of the heating equipment is based. When performing temperature-related operations, the heating equipment uses the operating temperature as a reference. For example, the heating equipment updates the displayed temperature to the user based on the operating temperature. Or, if the heating equipment has preset temperature-related safety measures, it determines whether to implement the safety measures based on the operating temperature. For instance, if the heating equipment has preset dry-burn protection rules, the heating equipment will automatically stop heating when the operating temperature exceeds a certain threshold.

[0044] In some implementations, the operating temperature is determined based on the temperature difference, including:

[0045] (1.1) When the temperature difference is greater than the difference threshold, the working temperature is determined as the detection temperature.

[0046] In some implementations, a temperature difference greater than a threshold indicates a detection error in the infrared temperature detection module. However, to improve the accuracy of the judgment and exclude temperature fluctuations caused by sudden events, the detected temperature can still be used as the operating temperature when the temperature difference is greater than the threshold.

[0047] In some implementations, the method further includes:

[0048] (1.2) When the temperature difference is greater than the difference threshold, reduce the working power of the heating equipment.

[0049] Specifically, if the temperature difference exceeds the difference threshold, it indicates that the infrared temperature detection module has a detection error. Regardless of the cause of the detection error, once it is confirmed that the infrared temperature detection module has a detection error, reducing the operating power of the heating equipment can slow down the heating rate of the cooking appliance, preventing the cooking appliance from becoming dangerous due to excessively high temperature or rapid heating, and ensuring heating safety.

[0050] In some implementations, the difference threshold can be greater than or equal to 10°C, preferably greater than or equal to 50°C.

[0051] In some implementations, the operating temperature is determined based on the temperature difference, including:

[0052] (1.3) When the temperature difference is greater than the difference threshold and the temperature difference continues to increase within a preset duration, the working temperature is determined as the alternative temperature.

[0053] Specifically, if the temperature difference is greater than the difference threshold and continues to increase within a preset duration, it is determined that the infrared temperature detection module is being interfered with. The detected temperature determined by the detection signal of the infrared temperature detection module deviates significantly from the actual temperature of the cooking appliance. If the detected temperature is still used as the working temperature, dangerous situations such as dry burning may occur. Therefore, the working temperature is determined as the alternative temperature for heating protection.

[0054] In some embodiments, the heating protection method provided in this application further includes: restoring the operating power of the heating device to perform heating.

[0055] Specifically, if the operating power of the heating device is reduced when the temperature difference is greater than the difference threshold, and the original operating power is defined as P1 and the reduced operating power as P2, then if the temperature difference continues to increase within a preset duration after the temperature difference is greater than the difference threshold, the operating power of the heating device will be restored to P1 for heating.

[0056] In some implementations, the preset duration can be in the range of [3s, 8s].

[0057] Please refer to the following: Figure 3 , Figure 3 This is another schematic flowchart of a heating protection method provided in an embodiment of the present invention. Figure 3 As shown, the method includes steps 310 to 320.

[0058] Step 310: Upon receiving the start signal, determine the heating rate based on the detected temperature; wherein, the start signal is used to activate the heating device to begin heating;

[0059] In some implementations, the user can trigger the generation of a start signal by pressing a button on the heating device, such as pressing the power button or the continue button.

[0060] In some implementations, users can trigger the generation of a start signal via remote network control or near-field network communication (e.g., Bluetooth, Wi-Fi, NFC, etc.).

[0061] It is understood that other methods can also be used to trigger the generation of the startup signal, and this application does not restrict the method of triggering the generation of the startup signal.

[0062] Furthermore, when the start signal is received, the detected temperature should begin to rise. However, when the heating panel is wet or there is water at the bottom of the cooking appliance, the infrared light will be refracted or scattered, which will reduce the amount of infrared light received by the infrared temperature detection module. Before the moisture evaporates, the rate of temperature rise obtained from the detection signal of the infrared temperature detection module will be low or even zero.

[0063] In some implementations, upon receiving a start signal, the operation of determining the heating rate based on the detected temperature is only performed if the detected temperature is lower than the execution temperature. Specifically, the execution temperature reflects the temperature close to when water boils. When the heating device is in a water-related function, such as boiling water, if the user reheats water close to boiling, the heating rate will tend to be 0 because the temperature remains constant when water boils. Therefore, determining the heating rate based on the detected temperature when it is lower than the execution temperature can improve the user experience and further ensure heating safety. Optionally, the execution temperature range is [85℃, 110℃].

[0064] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram of the temperature rise curves under different scenarios provided in embodiments of the present invention. For example... Figure 4As shown, under normal circumstances, the detected temperature will continue to rise. However, when the heating panel is wet or there is water at the bottom of the cooking appliance, the detected temperature will not rise much within the time range of T0 to T1, and can be regarded as always being zero. At this time, the error between the detected temperature and the actual temperature of the cooking appliance is very large. The water will not evaporate completely until time T2, and the detected temperature will return to normal. Therefore, if the working temperature is not re-determined within the time range of T0 to T2, dangerous situations such as dry burning can easily occur, affecting heating safety.

[0065] Step 320: When the detected heating rate is less than the first speed threshold, determine the start-up operating temperature as the alternative temperature.

[0066] Specifically, if the detected heating rate is less than the first speed threshold, it indicates that the infrared temperature detection module is malfunctioning. In this case, the alternative temperature will be used as the start-up operating temperature to ensure heating safety.

[0067] Furthermore, the meaning of start-up operating temperature is the same as that of operating temperature; for details, please refer to the rest of the instruction manual.

[0068] In some embodiments, the startup operating temperature mentioned in this application is an operating temperature determined within a preset startup time after receiving the startup signal, wherein the preset startup time is longer than the preset time in the following part of the specification. Optionally, the preset startup time is 5 minutes.

[0069] In some implementations, the first speed threshold can be in the range of (0, 5℃ / s), and preferably 2℃ / s.

[0070] In some implementations, the method further includes:

[0071] (2.1) After determining the preset time for the start-up working temperature to be the alternative temperature, the heating panel temperature is obtained, and the panel heating rate is determined based on the heating panel temperature.

[0072] (2.2) When the detected heating rate is less than the first speed threshold and the panel heating rate is greater than the second speed threshold, the start-up working temperature is determined as the alternative temperature.

[0073] Specifically, when the heating panel is damp or there is water at the bottom of the cooking appliance, the detected temperature will return to normal as the water evaporates. Therefore, the preset time reflects the time required for the water to evaporate completely. After the preset time, the water should have evaporated and the detected temperature should return to normal. However, if the detected temperature rise rate is less than the first speed threshold and the panel temperature rise rate is greater than the second speed threshold after the preset time, it indicates that the detected temperature is still abnormal. Possible causes include a malfunction of the infrared temperature detection module or water overflow from the cooking appliance. In this case, the backup temperature will still be used as the start-up operating temperature to ensure heating safety.

[0074] In some implementations, the preset time can be (0, 120s).

[0075] In some implementations, the second speed threshold can be in the range of [0.3℃ / s, 0.8℃ / s], and preferably 0.5℃ / s.

[0076] In some implementations, the start-up operating temperature is determined as the detection temperature when the detected heating rate is greater than or equal to a first speed threshold and the panel heating rate is greater than a second speed threshold, or when the detected heating rate is greater than or equal to the first speed threshold and the panel heating rate is less than or equal to the second speed threshold, or when the detected heating rate is less than the first speed threshold and the panel heating rate is less than or equal to the second speed threshold.

[0077] In some implementations, the method further includes:

[0078] (3.1) After determining the preset time of the start-up working temperature as the alternative temperature, the heating panel temperature is obtained, and the panel heating rate is determined based on the heating panel temperature.

[0079] (3.2) Obtain the operating power of the heating equipment.

[0080] (3.3) When the detected heating rate is less than the detection rate threshold, the working power is greater than the preset power threshold, the detected temperature is less than the preset temperature threshold, and the panel heating rate is greater than the panel speed threshold, the start-up working temperature is determined as the alternative temperature.

[0081] Furthermore, to improve detection accuracy, the infrared temperature detection module can be checked for abnormalities by combining the working power of the heating equipment and the detection temperature. If an abnormality is detected, the alternative temperature can be used as the start-up operating temperature.

[0082] In some implementations, the preset power threshold can be greater than or equal to 800W, and preferably 1000W.

[0083] In some implementations, the preset temperature threshold can be less than or equal to 100°C, and preferably 90°C.

[0084] In some implementations, the panel speed threshold can be in the range of [0.3℃ / s, 0.8℃ / s], and preferably 0.5℃ / s.

[0085] In some implementations, the detected temperature can be used as the start-up operating temperature when the detected heating rate is greater than or equal to a detection rate threshold, or the operating power is less than or equal to a preset power threshold, or the detected temperature is greater than or equal to a preset temperature threshold, or the panel heating rate is less than or equal to a panel speed threshold.

[0086] This application provides a heating protection method applied to a heating device equipped with an infrared temperature detection module. The method includes: acquiring a candidate temperature; determining a detection temperature based on the detection signal from the infrared temperature detection module; determining a temperature difference between the detection temperature and the candidate temperature; and determining the operating temperature based on the temperature difference. This application determines the operating temperature of the heating device based on the temperature difference between the candidate temperature and the detection temperature, thereby determining an operating temperature with minimal error in the current scenario based on the detection error of the infrared temperature detection module, thus ensuring the heating safety of the heating device and reducing the probability of accidents.
