[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, the heating equipment may have obstructions that affect the propagation of infrared rays. For example, when there is water at the bottom of the cooking appliance or the heating panel is too damp, the water can affect the propagation path of the infrared rays, causing refraction or scattering. Before the moisture evaporates completely, the infrared temperature detection module receives less infrared light, resulting in a significant difference between the detected temperature and the actual temperature of the cooking appliance. In such cases, the heating time may be excessively long, 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 provided in this application. The 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 detection heating rate based on the detection temperature; and determining an operating temperature as the candidate temperature when the detection heating rate is less than a first speed threshold. This application determines the operating temperature as the candidate temperature when the detection heating rate is less than the first speed threshold. This ensures the heating safety of the heating device and reduces the probability of accidents when the detection error of the infrared temperature detection module is large, by selecting a candidate temperature with a smaller error as the operating temperature.

[0021] The following describes the application scenarios of the heating protection method provided in the embodiments of the present invention.

[0022] Please see Figure 1 , Figure 1This 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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 determined by the infrared temperature detection module is taken as the operating temperature. 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 detection temperature rise rate can be calculated. If the detection temperature rise rate is less than a first speed threshold, the operating temperature is determined as a backup temperature. This ensures the heating safety of the heating device and reduces the probability of accidents, especially when the detection temperature rise rate is too low (i.e., the infrared temperature detection module has a large error). Furthermore, there are many backup temperatures to choose from, but the backup temperature must, like the detected temperature, reflect the actual temperature of the cooking appliance. Moreover, the backup temperature must still be able to detect the temperature normally even when the detected temperature is abnormal, thus ensuring heating safety. Understandably, under normal circumstances, the backup temperature may not be as accurate as the detected temperature. However, when the error of the detected temperature is large, the error of the backup temperature is smaller than that of the detected temperature. In this case, the backup temperature can also reflect the actual temperature of the cooking appliance, with a smaller error compared to using the detected temperature.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Step 210: Obtain alternative temperatures.

[0031] 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.

[0032] 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.

[0033] In other embodiments, the temperature of the heating panel can be obtained by detecting the temperature of the heating panel using temperature sensors such as infrared temperature detection modules and thermistors.

[0034] 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.

[0035] Step 220: Determine the detection temperature based on the detection signal from the infrared temperature detection module.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 can only reach the infrared temperature detection module after passing through the heating panel. When the heating panel is damp or there is water on the bottom of the cooking appliance, the amount of medium-wavelength infrared light received by the infrared temperature detection module will decrease, but the long-wavelength infrared light can still be received normally. Therefore, the temperature detection error is relatively large at this time, while the temperature detection of the heating panel is normal.

[0040] Step 230: Determine the heating rate based on the detected temperature.

[0041] Specifically, when the infrared temperature detection module is working properly, the temperature measurement is accurate. Understandably, the cooking appliance heats up rapidly during heating, resulting in a relatively high rate of temperature rise. However, in certain scenarios, such as when the heating panel is damp or there is water at the bottom of the cooking appliance, the infrared temperature detection module has a larger detection error, leading to inaccurate temperature measurements. Therefore, the rate of temperature rise obtained from the measured temperature will be lower than normal. Thus, the rate of temperature rise can be used to determine whether the infrared temperature detection module is working properly.

[0042] In some implementations, the detection heating rate is determined based on the detection temperature. This includes:

[0043] (1.1) When receiving the start signal, the heating rate is determined based on the detected temperature; wherein, the start signal is used to start the heating equipment.

[0044] 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.

[0045] 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).

[0046] 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.

[0047] Furthermore, upon receiving the start signal, the detected temperature should begin to rise. However, when the heating panel is damp or there is water at the bottom of the cooking appliance, the infrared light will be refracted or scattered, reducing the amount of infrared light received by the infrared temperature detection module. Before the moisture evaporates completely, the detected temperature will rise slowly or remain essentially unchanged. Therefore, upon receiving the start signal, the rate of temperature rise can be used to determine whether the detected temperature is normal.

[0048] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of the temperature rise curve during startup provided in an embodiment of the present invention. Figure 3 As shown, under normal circumstances, the detected temperature will continue to rise when the appliance is started. 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.

[0049] In some implementations, the detection heating rate is determined based on the detection temperature. This includes:

[0050] (1.2) When the detection temperature is less than the preset temperature threshold, the detection heating rate is determined based on the detection temperature.

[0051] Specifically, the infrared temperature detection module can be judged to be working properly by detecting the heating rate. However, in some scenarios, such as when the heating device is in the boiling water function, the temperature remains constant while the water is boiling, so the detected temperature also remains constant after the water boils. In this case, the detected heating rate will be close to zero. However, the detected temperature is accurate in this scenario, and there is no need to use the alternative temperature as the operating temperature. Therefore, when the detected temperature is greater than or equal to the preset temperature threshold, in order to eliminate the interference caused by the boiling water, the detected heating rate can be determined without relying on the detected temperature.

[0052] In some embodiments, the preset temperature threshold should be less than or equal to the boiling temperature. Optionally, the preset temperature threshold ranges from [80°C, 110°C], preferably 95°C.

[0053] Step 240: When the detected heating rate is less than the first speed threshold, determine the working temperature as the alternative temperature.

[0054] 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.

[0055] Furthermore, if the heating panel is damp before heating or there is water at the bottom of the cooking appliance, or if the user accidentally spills water on the heating panel during the heating process, the detected heating rate will be less than the first speed threshold. In this case, setting the working temperature as the alternative temperature can prevent the heating device from heating for too long and ensure heating safety.

[0056] In some implementations, when the detected heating rate is less than a first rate threshold, the operating temperature is determined as a candidate temperature, including:

[0057] (2.1) Determine the temperature difference between the candidate temperature and the detection temperature.

[0058] (2.2) When the detected heating rate is less than the first speed threshold and the temperature difference is greater than the difference threshold, the working temperature is determined as the alternative temperature.

[0059] Specifically, the above-mentioned section of the instruction manual states that under normal circumstances, the temperature difference between the candidate temperature and the detection temperature is small. Therefore, when the temperature difference exceeds the difference threshold, it can be determined that the error of the detection temperature is large. In order to prevent the cooking appliance from being dangerous due to excessive temperature or rapid heating and to ensure heating safety, the working temperature can be determined as the candidate temperature.

[0060] In some implementations, the first speed threshold can be in the range of (0, 5℃ / s), and preferably 2℃ / s.

[0061] In some implementations, the temperature difference between the detected temperature and the alternative temperature is the absolute value of (detected temperature minus alternative temperature).

[0062] In some implementations, the difference threshold can be greater than or equal to 5°C, preferably greater than or equal to 10°C.

[0063] In some implementations, when the detected heating rate is less than a first rate threshold and the temperature difference is greater than a difference threshold, the operating temperature is determined as a candidate temperature, including:

[0064] (2.2.1) When the detected heating rate is less than the first speed threshold, the temperature difference is greater than the difference threshold, and the detected temperature is less than the candidate temperature, the working temperature is determined as the candidate temperature.

[0065] Specifically, when the detection error of the infrared temperature detection module is large, the detected temperature is low because the temperature rises slowly. In this case, if the candidate temperature is detected normally, it should be greater than or equal to the detected temperature. Therefore, it is necessary not only that the detection temperature rise rate is less than the first speed threshold and the temperature difference is greater than the difference threshold, but also that the detected temperature is less than the candidate temperature before the working temperature is determined as the candidate temperature. This is to improve the accuracy of the detection error judgment and ensure heating safety.

[0066] In some implementations, please refer to [further details]. Figure 4 , Figure 4 This is another schematic flowchart of a heating protection method provided in an embodiment of the present invention. Figure 4 As shown, the method includes steps 310 to 360.

[0067] Step 310: Obtain alternative temperatures.

[0068] Step 320: Determine the detection temperature based on the detection signal from the infrared temperature detection module.

[0069] Step 330: Determine the heating rate based on the detected temperature.

[0070] Step 340: When the detected heating rate is less than the first rate threshold, the working temperature is determined as the alternative temperature.

[0071] For a detailed description of steps 310 to 340, please refer to steps 210 to 240, which will not be repeated here.

[0072] Step 350: After determining the preset time for the working temperature to be the alternative temperature, obtain the panel heating rate of the heating panel.

[0073] Specifically, when the heating panel is wet or there is water at the bottom of the cooking appliance, the detection error of the temperature will gradually decrease as the water evaporates. The preset time reflects the time required for the water to evaporate completely. After the preset time, the water will have evaporated completely, and the detection temperature should return to normal.

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

[0075] Step 360: 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 working temperature is determined as the alternative temperature.

[0076] Specifically, if the heating rate is less than the first speed threshold and the panel heating rate is greater than the second speed threshold after a preset time, it indicates that the detected temperature is still abnormal. Possible causes include the failure of the infrared temperature detection module or water overflow in the cooking appliance. In this case, the backup temperature will still be used as the working temperature to ensure heating safety.

[0077] In some implementations, the second speed threshold can be in the range of [0.3℃ / s, 0.8℃ / s], and preferably 0.5℃ / s.

[0078] In some implementations, the 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.

[0079] In some implementations, step 360, when detecting that the heating rate is less than a first speed threshold and the panel heating rate is greater than a second speed threshold, determines the operating temperature as a candidate temperature, including:

[0080] (3.1) Determine the temperature difference between the candidate temperature and the detection temperature.

[0081] For specific steps, please refer to the corresponding section of the instruction manual; they will not be repeated here.

[0082] (3.2) When the detected heating rate is less than the first speed threshold, the panel heating rate is greater than the second speed threshold, and the temperature difference is greater than the difference threshold, the working temperature is determined as the alternative temperature.

[0083] For specific steps, please refer to the corresponding section of the instruction manual; they will not be repeated here.

[0084] In some implementations, the difference threshold can be greater than or equal to 5°C, preferably greater than or equal to 10°C.

[0085] In some implementations, the operating temperature is determined as the detection temperature when the detected heating rate is greater than or equal to a first speed threshold, or the panel heating rate is less than or equal to a second speed threshold, or the temperature difference is less than or equal to a difference threshold.

[0086] In some embodiments, the heating protection method provided in this application further includes:

[0087] (4.1) Obtain the heating rate of the heating panel.

[0088] (4.2) Obtain the operating power of the heating equipment.

[0089] (4.3) When the detection heating rate is less than the detection speed threshold, the working power is greater than the preset power threshold, the detection temperature is less than the preset temperature threshold, and the panel heating rate is greater than the panel speed threshold, the working temperature is determined as the alternative temperature.

[0090] Specifically, in order to improve the 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. When an abnormality is detected, the alternative temperature is used as the working temperature to ensure heating safety.

[0091] In some implementations, the preset power threshold can be greater than or equal to 800W, and preferably 1000W.

[0092] In some implementations, the preset temperature threshold can be less than or equal to 100°C, and preferably 90°C.

[0093] In some implementations, the panel speed threshold can be in the range of [0.3℃ / s, 0.8℃ / s], and preferably 0.5℃ / s.

[0094] In some implementations, the detected temperature can be used as the 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.

[0095] This application provides a heating protection method applied to a heating device 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 detection heating rate based on the detection temperature; and determining an operating temperature as the candidate temperature when the detection heating rate is less than a first speed threshold. This application determines the operating temperature as the candidate temperature when the detection heating rate is less than the first speed threshold. This ensures the heating safety of the heating device and reduces the probability of accidents when the infrared temperature detection module has a large detection error, resulting in slow temperature rise.
