[0016] 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.

[0017] Currently, with the development of home appliance technology, infrared detection modules are increasingly being used in heating equipment for temperature detection. Infrared detection modules detect temperature by receiving infrared signals radiated by the object being detected (such as cooking utensils).

[0018] However, if the infrared signal encounters contaminants during transmission, such as if the heating device has a panel, a heavily soiled panel can interfere with the normal transmission of the infrared signal, causing abnormal temperature detection results from the infrared detection module and affecting heating safety.

[0019] Furthermore, although the cleanliness status can be detected using infrared emitters and receivers based on the abnormal infrared signal characteristics when the heating equipment is dirty, the detection signal received by the heating equipment will also change when it is carrying cooking utensils (load). Moreover, the signal strength of the detection signal received by the infrared detection module when the heating equipment is dirty and under load is greater than when the heating equipment is clean and unloaded. Therefore, it is difficult to judge the cleanliness status of the heating equipment.

[0020] To address the aforementioned problems, the inventors have proposed a detection and control method, apparatus, heating device, and storage medium as provided in this application. This method is applied to a heating device equipped with an infrared detection module and includes: acquiring a detection signal obtained by the infrared detection module; determining the operating state of the heating device; and, when the heating device is in an unloaded state, determining the cleanliness state of the heating device based on the detection signal. This application determines the cleanliness state of the heating device when it is in an unloaded state, which improves the accuracy of cleanliness state determination, ensuring that the heating device operates only when clean and guaranteeing heating safety.

[0021] The application scenarios of the detection and control method provided in the embodiments of the present invention will be introduced below.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a detection and control method provided in an embodiment of the present invention. For example... Figure 1As shown, this method is applied to a heating device 100 with an infrared detection module. The heating device 100 includes a device body 140 and an infrared detection module 110 disposed on the device body. The heating device 100 can heat a cooking appliance 200 placed on the device body 140 and detect the cleanliness of a panel 120 based on the detection signal from the infrared detection module 110. The infrared detection module 110 can be used to detect the temperature and cleanliness of the cooking appliance 200. Optionally, the infrared detection module 110 can also be used to detect the color of the cooking appliance 200.

[0023] In some embodiments, the heating device 100 further includes a panel 120 disposed on the device body, on which the cooking utensil 200 can be placed. Optionally, the panel 120 may include a glass panel, a ceramic panel, or a microcrystalline panel, etc.

[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] In some embodiments, the infrared detection module 110 includes a first detection module 113, which receives a first radiation signal emitted by the cooking appliance 200. The first radiation signal reaches the infrared detection module 110 after passing through the panel 120. Due to interference from the panel, the first radiation signal measured by the infrared detection module 110 has errors and cannot be directly used to determine the temperature of the cooking appliance 200. To improve the accuracy of temperature detection, the infrared detection module 110 also includes a second detection module 114. The second detection module 114 receives a second radiation signal emitted by the panel 120. Thus, based on the first and second radiation signals, the second signal intensity of the infrared signal actually emitted by the cooking appliance 200 can be determined for temperature detection.

[0026] Optionally, the first detection module 113 and / or the second detection module 114 may employ infrared phototubes.

[0027] In some embodiments, the infrared detection module 110 further includes an infrared emitting diode 111 and an infrared receiving diode 112, because Figure 1 The infrared signal emitted by the cooking appliance 200 needs to pass through the panel 120 to be received by the first detection module 113. Therefore, Figure 1 The mid-infrared emitting tube 111 and the infrared receiving tube 112 are used to perform cleanliness detection on the panel 120. The infrared emitting tube 111 is used to emit a first detection signal, and the infrared receiving tube 112 is used to receive a second detection signal reflected from the first detection signal. The second detection signal can be used to determine the cleanliness status of the heating equipment, which will be elaborated in the following embodiments.

[0028] In some embodiments, the infrared emitting tube 111 and the infrared receiving tube 112 also have a color detection function, that is, the second detection signal can also be used to determine the color of the cooking appliance 200, which will be elaborated in the following embodiments.

[0029] Optionally, the infrared emitting tube 111 and / or the infrared receiving tube 112 may be infrared phototubes.

[0030] It should be noted that, Figure 1 This is merely an illustrative representation of one possible structure for the heating device. Figure 1 If the panel 120 is severely dirty when the mid-infrared detection module 110 performs temperature detection, the infrared signal received by the first detection module 113 will be abnormal, leading to abnormal temperature detection results and affecting heating safety. It is understood that in other structures that implement this application, the infrared detection module 110 may be interfered with by severe dirt in other structures during temperature detection. Therefore, the infrared detection module 110 in this application is not limited to detecting the degree of dirt on the panel 120. When the structure of the heating equipment is different, the infrared detection module 110 can be used to detect the degree of dirt on different components. Figure 1 This is merely an example for illustration.

[0031] 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.

[0032] It should be noted that the operating states of heating equipment include no-load state and load state.

[0033] In some implementations, "no-load state" refers to the heating device not having any cooking appliances placed on it, while "load state" refers to the heating device having cooking appliances placed on it.

[0034] In other embodiments, the no-load state refers to the heating device not having any cooking utensils placed on it or the heating device having cooking utensils placed on it but not in a heating state, while the load state refers to the heating device having cooking utensils placed on it while in a heating state.

[0035] For ease of explanation, the embodiments of this application use the example of an unloaded state (where no cooking utensils are placed on the heating device) and a loaded state (where cooking utensils are placed on the heating device).

[0036] Furthermore, the detection results of cleanliness status can be affected when the heating equipment is operating under load.

[0037] Specifically, this application determines the cleanliness of the heating device based on the signal strength of the detection signal. However, when cooking utensils are placed on the heating device, the color or material of the utensils will affect the signal strength of the detection signal obtained by the infrared detection module.

[0038] For example, under load, if the cooking utensils placed on the heating device are of different colors or materials during two cleanliness status tests, the signal strength of the detection signal may be the same even if the cleanliness status of the heating device is different during the two cleanliness status tests. That is, the detection results of the cleanliness status test may be the same. Therefore, the detection results obtained by performing cleanliness status test when the heating device is under load are inaccurate. Therefore, this application performs cleanliness status test under no-load conditions to improve the accuracy of cleanliness status judgment.

[0039] Please see Figure 2 , Figure 2 This is a schematic flowchart of a detection and control method provided in an embodiment of the present invention. Figure 2 As shown, this method is applied to heating equipment with an infrared detection module, such as... Figure 1 The heating device 100 in the middle, the method includes: steps 310 to 330.

[0040] Step 310: Obtain the detection signal obtained by the infrared detection module.

[0041] In some implementations, the infrared detection module includes an infrared emitting module and an infrared receiving module, and acquires the detection signal obtained by the infrared detection module, including: (1) Control the infrared emitting module to emit the first detection signal.

[0042] (2) Obtain the second detection signal received by the infrared receiving module; wherein the second detection signal is obtained by reflecting the first detection signal.

[0043] Further, step 330, which determines the cleanliness status of the heating equipment based on the detection signal, includes: (3) Determine the cleanliness status of the heating equipment based on the second detection signal.

[0044] Specifically, the detection signal received by the infrared detection module refers to the second detection signal received by the infrared receiving tube.

[0045] In some implementations, the cleanliness of the heating equipment can be determined based on the signal strength of the second detection signal.

[0046] It should be noted that the infrared receiver tube receives the second detection signal obtained after the first detection signal is reflected. However, when the heating device is under load, cooking utensils of different materials or colors have different abilities to reflect infrared signals. For example, the signal strength of the infrared signal reflected by black cooking utensils is weaker than that reflected by silver cooking utensils. At this time, the signal strength of the second detection signal is not very effective in judging the cleanliness status. Therefore, when the heating device is under load, the cleanliness status of the heating device cannot be accurately determined based on the second detection signal.

[0047] In some embodiments, the first detection signal emitted by the infrared emitting module is an infrared signal, the wavelength range of which can be [500nm, 1500nm], preferably 940nm.

[0048] Step 320: Determine the operating status of the heating equipment.

[0049] Specifically, the working state of the heating equipment is divided into no-load state and load state. The no-load state can be further divided into clean state and dirty state. The working state of the heating equipment can be determined based on the detection signal obtained by the infrared detection module.

[0050] In some implementations, a clean state means that the temperature detection signal of the infrared detection module is unaffected or minimally affected, indicating that the temperature detection of the heating device is normal.

[0051] In some implementations, the dirty state refers to the temperature detection signal of the infrared detection module at this time (e.g., Figure 1 The first radiation signal received by the first detection module 113 in the middle will be affected by certain components (e.g., Figure 1 If the panel 120 in the middle is dirty and affected, that is, the temperature detection of the heating equipment is abnormal. If the heating equipment is heated in this case, it may be dangerous due to the abnormal temperature detection, such as dry burning or fire.

[0052] In some implementations, step 320 includes: (1) Determine the first signal strength of the second detection signal.

[0053] (2) When the first signal strength is less than or equal to the no-load strength threshold, the working state of the heating equipment is determined to be no-load state.

[0054] In some implementations, since the signal strength of the second detection signal under no-load conditions is less than the signal strength of the second detection signal under load conditions, step 320 further includes: when the first signal strength is greater than the no-load strength threshold, determining that the operating state of the heating device is the load state.

[0055] In some implementations, step 320 includes: (1) Obtain the operating current of the heating equipment.

[0056] (2) When the working current is less than or equal to the preset current threshold, the working state of the heating equipment is determined to be no-load state.

[0057] In some implementations, a preset current threshold is used. I 1 The current is less than the operating current corresponding to the current function of the heating equipment. I 0 Preferably, I 1 ≤0.5 I 0 It is understandable that the operating current of a heating device will change as it switches between different functions. For example, when the heating device is an induction cooker, the operating current for the hot pot function and the stir-fry function are different, and in this case, the preset current threshold... I 1 They are not the same either.

[0058] In some implementations, when the operating current is greater than a preset current threshold, the operating state of the heating device is determined to be a load state.

[0059] In some embodiments, the heating device further includes a weight sensor, and step 320 includes: (1) Obtain the detected weight of the weight sensor.

[0060] (2) When the detected weight is less than or equal to the preset weight threshold, the working state of the heating equipment is determined to be no-load state.

[0061] In some implementations, the preset weight threshold value is related to the type of heating device. Different types of heating devices heat different types of cooking utensils, and therefore the preset weight threshold value is also different. Optionally, the preset weight threshold value is greater than or equal to 1 kg.

[0062] In some implementations, when the detected weight exceeds a preset weight threshold, the heating device is determined to be in a load state.

[0063] Step 330: When the heating equipment is in an unloaded state, determine the cleanliness status of the heating equipment based on the detection signal.

[0064] In some implementations, step 330 includes: When the first signal strength is greater than or equal to a preset strength threshold, the cleanliness of the heating equipment is determined to be dirty.

[0065] Specifically, the preset intensity threshold is the boundary between the clean state and the dirty state when the device is unloaded. When the first signal intensity is greater than or equal to the preset intensity threshold, the clean state of the heating device is determined to be the dirty state; when the first signal intensity is less than the preset intensity threshold, the clean state of the heating device is determined to be the clean state.

[0066] Furthermore, although the signal strength may be greater than or equal to the preset strength threshold under load, step 330 is the determination of the cleanliness state under no-load conditions, and therefore is not affected by the load state.

[0067] In some implementations, step 330 further includes: (1) When the first signal strength is less than the preset strength threshold, if the change in the first signal strength within the first preset time is greater than the preset amplitude threshold, then color detection is performed.

[0068] (2) Temperature detection is performed based on the results of color detection.

[0069] In some implementations, a first signal strength less than a preset strength threshold indicates that the heating device is clean. When the heating device is clean, if the change in the first signal strength within a first preset time period is greater than a preset amplitude threshold, it indicates that the user is likely to have placed a cooking appliance on the heating device. In this case, color detection can be performed to determine the color of the cooking appliance, and temperature detection can be performed based on the color of the cooking appliance to improve the accuracy of temperature detection.

[0070] Furthermore, as stated above in the specification, the signal strength under load is greater than the signal strength under no-load. Therefore, in some embodiments, step 330 is to perform color detection if the rise of the first signal strength within a first preset time period is greater than a preset amplitude threshold.

[0071] In some implementations, the value of the first preset time can be set as needed, and this application does not impose any restrictions. Optionally, the value range of the first preset time can be [1s, 3s], preferably less than [1s, 2s].

[0072] In some implementations, the value of the preset amplitude threshold can be set as needed, and this application does not impose any restrictions. Optionally, the range of the preset amplitude threshold can be [300, 800], preferably less than (500, 800).

[0073] In some implementations, step 330 further includes: When the heating equipment is in a dirty state instead of a clean state, one of the first treatment measures, the second treatment measures, and the third treatment measures shall be implemented. The first treatment measure includes stopping the heating.

[0074] The second action includes issuing a reminder message.

[0075] The third action includes stopping heating and issuing a warning message.

[0076] Specifically, if heating equipment is in a dirty state when it is in a clean state, a safety accident may occur. Therefore, it is necessary to take measures to deal with the situation and ensure heating safety.

[0077] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram illustrating the signal strength threshold of a detection and control method provided in an embodiment of this application. Figure 3 As shown, Figure 3 This includes the preset strength threshold H1 and the no-load strength threshold H2.

[0078] In some implementations, the heating device is determined to be in an unloaded state when the first signal strength of the second detection signal is less than or equal to the no-load strength threshold H2.

[0079] In some implementations, when the heating device is in an unloaded state, if 0 < the first signal intensity of the second detection signal < a preset intensity threshold H1, the cleanliness state of the heating device is determined to be clean.

[0080] In some implementations, when the heating equipment is in an unloaded state, if the preset intensity threshold H1 ≤ the signal strength of the second detection signal ≤ the unload intensity threshold H2, the cleanliness state of the heating equipment is determined to be a dirty state.

[0081] In some implementations, the no-load strength threshold ranges from [800, 1400].

[0082] In some implementations, the preset intensity threshold ranges from 0 to 500.

[0083] Furthermore, as described above in the specification, the detection signal can also be used for color detection. Therefore, the intensity threshold in the embodiments of this application may also include the color boundary threshold H3.

[0084] In some implementations, when the no-load intensity threshold H2 < the first signal intensity of the second detection signal ≤ the color boundary threshold H3, the working state of the heating device is determined to be the load state and the color of the cooking appliance is the first color.

[0085] In some implementations, when the color boundary threshold H3 is less than the first signal strength of the second detection signal, the heating device is determined to be in a load state and the cooking appliance is in the second color.

[0086] In some implementations, the first color is black and the second color is silver, in which case the color boundary threshold value ranges from 1500.

[0087] It is understood that this application is not limited to setting only one color boundary threshold, but can also set multiple color boundary thresholds to more accurately determine the color of the cooking appliance when the heating device is under load. Furthermore, the color boundary thresholds should be greater than the no-load intensity threshold H2 and be unequal to each other.

[0088] Please refer to the following: Figure 4 , Figure 4 This is another schematic flowchart illustrating a detection and control method provided in an embodiment of this application. Figure 4 As shown, Figure 4 This includes steps 410 to 430.

[0089] Step 410: Obtain the second detection signal detected by the infrared detection module.

[0090] Step 420: Determine the operating status of the heating equipment.

[0091] Step 430: When the heating equipment is in a load state, perform color detection according to preset detection rules; wherein, the preset detection rules include: performing color detection within a first preset period and stopping color detection within a second preset period, with the first preset period and the second preset period being set alternately.

[0092] For details of steps 410 to 420, please refer to the description of steps 310 to 320 in this application specification, which will not be repeated here.

[0093] Specifically, when the heating equipment is under load, performing color detection and then temperature detection based on the color detection results can improve the accuracy of temperature detection. However, in order to save power and reduce the power-on time of the color detection module to improve its performance (e.g., ... Figure 1 The lifespan of the infrared emitting tube 111 and infrared receiving tube 112 can be determined by color detection according to preset detection rules.

[0094] In some implementations, the first preset period ranges from 1 to 5 seconds, and preferably, the first preset period can be 2 seconds.

[0095] In some implementations, the second preset period is in the range of 25 to 35 seconds, and preferably, the second preset period can be 28 seconds.

[0096] It is understood that the duration of the first and second preset periods can be set as needed, and this application does not impose any restrictions.

[0097] For example, alternating between the first preset period and the second preset period means that after the first preset period ends, the second preset period begins, and after the second preset period ends, the first preset period begins, and so on. For example, if the first preset period is 2 seconds and the second preset period is 28 seconds, then color detection according to the preset detection rules means performing color detection for 2 seconds, then stopping color detection for 28 seconds, then performing color detection for 2 seconds again, then stopping color detection for 28 seconds, and so on.

[0098] This application provides a detection and control method applied to a heating device with an infrared detection module. The method includes: acquiring a second detection signal detected by the infrared detection module; determining the operating state of the heating device; and, when the heating device is in an unloaded state, determining the cleanliness state of the heating device based on the second detection signal. This application determines the cleanliness state of the heating device when it is in an unloaded state, which improves the accuracy of cleanliness state judgment, ensuring that the heating device operates when clean and guaranteeing heating safety.

[0099] Please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of the structure of a detection and control device provided in an embodiment of the present invention.
