[0061] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0063] In the embodiments of the present application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.
[0064] The technical solution provided in the embodiment of the present application can be applied to the scene of temperature detection of electromagnetic heating appliances. Electromagnetic heating appliances, such as induction cookers, have become common appliances in life and can be used to heat appliances to be heated, such as pots. During the operation of the electromagnetic heating appliance, it is necessary to detect the temperature of the heating so as to adjust the working mode of the electromagnetic heating appliance in time or move the appliance to be heated.
[0065] In the prior art, a single-channel NTC temperature sensor is usually provided in the electromagnetic heating device, and the probe of the NTC temperature sensor is provided in the middle position of the heating panel of the electromagnetic heating device. The temperature of the electromagnetic heating device is detected by the single-channel NTC temperature sensor, so as to determine the temperature of the device to be heated placed on the heating panel of the electromagnetic heating device, so that the electromagnetic heating device can adjust the current heating mode according to the detected temperature.
[0066] However, when placing the appliance to be heated on the panel of the electromagnetic heating appliance, the appliance to be heated may not be placed in the center of the heating panel, i.e., it is offset, so that the single-channel NTC temperature sensor cannot detect the temperature. In addition, the single-channel NTC temperature sensor cannot detect the offset of the appliance to be heated, and the electromagnetic heating appliance may be out of control due to uneven heating of the appliance to be heated due to the offset, thereby causing an accident.
[0067] In order to solve the problem in the prior art that a single-channel NTC temperature sensor cannot detect the bias of the device to be heated placed on the electromagnetic heating device, at least three NTC temperature sensors can be set on the electromagnetic heating device, including a first NTC temperature sensor that can directly contact the device to be heated and accurately detect the temperature of the device to be heated, and at least two second NTC temperature sensors evenly arranged on both sides of the first NTC temperature sensor. During the operation of the electromagnetic heating device, by collecting the temperatures detected by at least three NTC temperature sensors and processing the multiple temperatures, it is determined whether the device to be heated is biased. Since multiple NTC temperature sensors are set at different positions of the heating panel, the temperatures of multiple different positions can be collected, which effectively improves the accuracy of the detected temperature, thereby accurately judging whether a bias problem occurs during the use of the electromagnetic heating device.
[0068] Figure 1 This is a schematic diagram of the structure of an electromagnetic heating device provided in an embodiment of the present application. Figure 1 As shown, the electromagnetic heating device includes NTC temperature sensor 1, NTC temperature sensor 2 and NTC temperature sensor 3. Among them, NTC temperature sensor 1 is arranged in the middle of the electromagnetic heating panel, and NTC temperature sensor 2 and NTC temperature sensor 3 are respectively placed on both sides of NTC sensor 1. Figure 1 In the embodiment, the probe of NTC temperature sensor 1 is directly in contact with the appliance to be heated placed on the heating panel, so as to accurately detect the temperature of the appliance to be heated. The probes of NTC temperature sensor 2 and NTC temperature sensor 3 are both located below the heating panel and directly in contact with the heating panel, so as to detect the temperature of the heating panel. Figure 1 The structure shown is only illustrated by taking three NTC temperature sensors as an example, but it does not mean that the embodiments of the present application are limited to this.
[0069] For example, when the NTC temperature sensor 2 and the NTC temperature sensor 3 are placed on both sides of the NTC sensor 1, the NTC temperature sensor 1, the NTC temperature sensor 2, and the NTC temperature sensor 3 can be arranged in a straight line, or in other arrangements, which can be set according to the actual situation of the electromagnetic heating device. For example, if the electromagnetic heating device is a long strip electromagnetic cooker, the NTC temperature sensor 1, the NTC temperature sensor 2, and the NTC temperature sensor 3 can be arranged in a straight line on the heating panel of the electromagnetic cooker. The embodiment of the present application does not impose any limitation on the arrangement of multiple NTC temperature sensors.
[0070] In a possible implementation, the position of the probe of the NTC temperature sensor 1 can be similar to that of the NTC temperature sensor 2 and the NTC temperature sensor, that is, the probe of the NTC temperature sensor 1 can also be located below the heating panel to detect the temperature of the heating panel. The specific setting can be made according to the actual situation of the electromagnetic heating device, and the embodiment of the present application does not make specific limitations on this. Of course, the probes of the NTC temperature sensor 2 and the NTC temperature sensor 3 can also be set to be similar to that of the NTC temperature sensor 1, only all the NTC temperature sensors are set to contact the device to be heated on the heating panel.
[0071] In passing Figure 1 When the structure shown performs temperature detection on the electromagnetic heating device, the temperature detection on the electromagnetic heating device can be performed by using three NTC temperature sensors, which can effectively improve the accuracy of temperature detection.
[0072] The detection method of the electromagnetic heating device provided by the present application will be described in detail below through specific embodiments. It is understandable that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0073] Figure 2A flow chart of a detection method for an electromagnetic heating device provided in an embodiment of the present application. The detection method for an electromagnetic heating device can be executed by software and / or hardware devices. For example, the hardware device can be a detection device for an electromagnetic heating device, and the detection device for an electromagnetic heating device can be an electromagnetic heating device or a processing chip in the electromagnetic heating device. For example, see Figure 2 As shown, the detection method of the electromagnetic heating device may include:
[0074] S201. When the duration of the electromagnetic heating device entering the working state reaches a first duration, collecting a current first temperature of the first NTC temperature sensor and a current second temperature of each of the at least two second NTC temperature sensors.
[0075] For example, in order to further improve the accuracy of temperature detection, the NTC temperature sensor can be set to Figure 1 As shown, the first NTC temperature sensor is used to detect the temperature of the appliance to be heated, and the second NTC temperature sensor is used to detect the temperature of the heating panel of the electromagnetic heating appliance.
[0076] In an embodiment of the present application, a first NTC temperature sensor is arranged in the middle of the heating panel of the electromagnetic heating device, and at least two second NTC temperature sensors are arranged on both sides of the first NTC temperature sensor at a preset interval. For example, if the number of the second NTC temperature sensors is 4, the 4 NTC temperature sensors can be evenly arranged on both sides of the first NTC temperature sensor. The preset interval can be set according to the size of the heating panel of the electromagnetic heating device and the number of the second NTC temperature sensors. For example, if the shape of the heating panel is a circle with a radius of 10 cm and there are 6 NTC temperature sensors, then in order to evenly arrange the 6 NTC temperature sensors on the heating panel, the preset interval can be set to 3 cm. The embodiment of the present application does not specifically limit the preset interval.
[0077] It is understandable that when the first NTC temperature sensor and the second NTC temperature sensor collect temperature, the temperature can be collected through the probes installed therein. The embodiment of the present application is only described by taking this as an example, but it does not mean that the embodiment of the present application is limited to this.
[0078] For example, the first duration may be 3 minutes or 5 minutes, and may be specifically set according to the working mode or type of the electromagnetic heater device, etc., and the embodiment of the present application does not impose any limitation on this.
[0079] For example, before the electromagnetic heating device enters the working state for a first time, the current fifth temperature of the first NTC temperature sensor and the current sixth temperature of at least two second NTC temperature sensors can be collected when the electromagnetic heating device enters the working state for a third time; if the fifth temperature and the plurality of sixth temperatures are both greater than the preset ambient temperature, it is determined that all NTC temperature sensors are working normally. The third time can be 1 minute, or other time that is less than the first time, and the embodiment of the present application does not specifically limit the third time. The preset ambient temperature can be set according to the use environment of the electromagnetic heating device, and the embodiment of the present application does not specifically limit this.
[0080] It can be understood that if the fifth temperature and the plurality of sixth temperatures are all lower than the preset ambient temperature, it can be determined that the electromagnetic heating device has a fault. At this time, the electromagnetic heating device can be controlled to exit the working state to avoid accidents.
[0081] In the embodiment of the present application, when the electromagnetic heating device enters the working state for a third time, temperature acquisition is performed, and when the fifth temperature of the first NTC temperature sensor and the sixth temperature of at least two second NTC temperature sensors acquired are both greater than the preset ambient temperature, it is determined that all NTC temperature sensors are working normally. The working state of the NTC temperature sensor is determined before the temperature of the electromagnetic heating device is detected, thereby ensuring that the temperature acquisition can be performed accurately.
[0082] S202: Detect whether the device to be heated placed on the electromagnetic heating device is biased according to the first temperature and at least two second temperatures.
[0083] For example, the appliance to be heated may be a pot or a kettle, and this embodiment of the present application does not specifically limit this.
[0084] For example, when detecting whether a device to be heated placed on the electromagnetic heating device is biased according to the first temperature and at least two second temperatures, there are the following two possible implementation methods:
[0085] In a possible implementation, a first temperature difference of each of at least two second temperatures minus the first temperature can be determined; if at least one of the at least two first temperature differences is greater than or equal to the first preset temperature difference, it is determined that the device to be heated is biased.
[0086] For example, the first preset temperature difference can be 1 degree Celsius or 3 degrees Celsius, and the embodiment of the present application does not impose any limitation on the first preset temperature difference. If at least one of the at least two first temperature differences is greater than or equal to the first preset temperature difference, it means that the temperature detected by the first NTC temperature sensor located in the middle of the heating panel of the electromagnetic heating device is greater than the temperature detected by at least one second NTC temperature sensor located on both sides of the heating panel, which can determine that the device to be heated is biased. For example, there are two second NTC temperature sensors in the device to be heated, which are located on the left and right sides of the first NTC temperature sensor respectively. When it is detected that the detected temperature of the first NTC temperature sensor is lower than the detected temperature of the second NTC temperature sensor on the right, it can be determined that the device to be heated is not placed above the first NTC temperature sensor, that is, the device to be heated is biased.
[0087] In the embodiment of the present application, when the first temperature difference between the first temperature and each second temperature is less than or equal to the first preset temperature difference, and at least one second temperature difference is greater than or equal to the second preset temperature difference, it is determined that the device to be heated placed on the electromagnetic heating device is biased. The accuracy of temperature detection can be effectively improved, thereby accurately determining whether the device to be heated is biased, preventing accidents, and improving the safety of the electromagnetic heating device.
[0088] In an embodiment of the present application, when the temperature difference between the first temperature and any second temperature is greater than or equal to the first preset temperature, the bias of the appliance to be heated is determined, that is, the detection temperature of the first NTC temperature sensor at the middle position of the heating panel is greater than the detection temperature of any second NTC temperature sensor at both sides, which can effectively improve the accuracy of judging whether the appliance to be heated is biased.
[0089] In another possible implementation, the second temperature difference between any two adjacent second NTC temperature sensors among at least two second NTC temperature sensors can be determined; if the first temperature is greater than all the second temperatures, and there is at least one second temperature difference greater than or equal to the second preset temperature difference, it is determined that the device to be heated is biased. The second preset temperature difference can be 30 degrees Celsius or 40 degrees Celsius, which can be set according to the actual situation such as the function of the electromagnetic heating device or the installation position of the second NTC temperature sensor. The embodiment of the present application does not impose any limitation on the second preset temperature difference.
[0090] It can be understood that since the first temperature is the temperature of the heated device placed on the heating panel at the middle position of the heating panel, when the device to be heated is biased, among at least two second NTC temperature sensors, there is at least one second NTC temperature sensor where the upper position of the heating panel detected is not in contact with the device to be heated, resulting in a large temperature difference between the temperature detected by the second NTC temperature sensor and the temperature detected by the adjacent second NTC temperature sensor, that is, causing the second temperature difference to be greater than or equal to the second preset temperature difference.
[0091] For example, when the number of second NTC temperature sensors is two, i.e., they are placed on the left and right sides of the first NTC temperature sensor respectively, if the temperature detected by the first NTC temperature sensor is greater than or equal to the temperature detected by the two second NTC temperature sensors, and the temperature difference between the temperatures collected by the two second NTC temperature sensors is greater than 30 degrees Celsius, it is determined that the appliance to be heated is biased.
[0092] In the embodiment of the present application, when the detection temperature of the first NTC temperature sensor in the middle position is higher than the detection temperatures of all the second NTC temperature sensors, the bias problem of the device to be heated is detected based on the temperature difference between the detection temperatures of the second NTC temperature sensors installed on both sides, thereby effectively improving the accuracy of detecting the bias situation of the device to be heated.
[0093] S203: If the device to be heated is offset, a prompt message is output, where the prompt message is used to remind the user to move the current placement position of the device to be heated.
[0094] For example, the prompt information may be a buzzer set on the electromagnetic heating device that emits a buzzer sound, for example, the buzzer emits three buzzers to prompt the user that the device to be heated is offset, so that the user moves the device to be heated to the correct position, for example, the central position of the heating panel, so that the device to be heated is evenly heated. The embodiments of the present application do not specifically limit the prompt information.
[0095] It can be seen that the detection method of the electromagnetic heating device provided in the embodiment of the present application is applied to the electromagnetic heating device, and the electromagnetic heating device includes a first NTC temperature sensor and at least two second NTC temperature sensors, the first NTC temperature sensor is arranged in the middle position of the heating panel of the electromagnetic heating device, and at least two second NTC temperature sensors are arranged on both sides of the first NTC temperature sensor at a preset interval. When the duration of the electromagnetic heating device entering the working state reaches the first duration, the method collects the current first temperature of the first NTC temperature sensor and the current second temperature of each second NTC temperature sensor in the at least two second NTC temperature sensors; according to the first temperature and at least two second temperatures, detect whether the device to be heated placed on the electromagnetic heating device is biased; if the device to be heated is biased, output a prompt message, and the prompt message is used to remind the user to move the current placement position of the device to be heated. The technical solution provided in the embodiment of the present application can simultaneously perform temperature detection on the middle position and the positions on both sides of the heating panel of the electromagnetic heating device, and determine the bias problem of the device to be heated according to the first temperature of the middle position and the multiple second temperatures of the positions on both sides. The accuracy of the temperature device can be effectively improved, and the accuracy of determining the bias problem of the device to be heated can be improved, thereby effectively avoiding the problem of loss of control of the electromagnetic heating device.
[0096] In another embodiment of the present application, the failure of the NTC temperature sensor can also be detected. For details, see Figure 3 As shown, Figure 3 A schematic diagram of a process for detecting failure of an NTC temperature sensor provided in an embodiment of the present application. Figure 3 As shown, detecting whether the NTC temperature sensor is failed may include the following steps:
[0097] S301. If the device to be heated is not biased, then when the time when the electromagnetic heating device enters the working state reaches a second time, the current third temperature of the first NTC temperature sensor and the current fourth temperature of each of the at least two second NTC temperature sensors are collected, and the second time is greater than the first time.
[0098] For example, the method for collecting temperature by the first NTC temperature sensor and the second NTC temperature sensor can be referred to the above embodiment, and the embodiment of the present application will not be repeated here.
[0099] It is understandable that the second duration is greater than the first duration, that is, the failure problem of the NTC temperature sensor is detected only when it is determined that there is no bias problem in the appliance to be heated. If it is detected that the appliance to be heated is biased during the first duration, the user is reminded to move the pot to eliminate the bias problem of the appliance to be heated. Therefore, detecting the failure problem of the NTC temperature sensor when the second duration is reached can improve the accuracy of the failure problem detection and avoid the influence of the bias of the appliance to be heated on the failure problem.
[0100] S302: Determine whether there is a failed NTC temperature sensor in the first NTC temperature sensor and the second NTC temperature sensor according to the third temperature and the plurality of fourth temperatures.
[0101] For example, when determining a failed NTC temperature sensor from the first NTC temperature sensor and the second NTC temperature sensor based on the third temperature and multiple fourth temperatures, the third temperature and the multiple fourth temperatures can be compared with the second preset protection temperature. If the third temperature and the multiple fourth temperatures are all lower than the second preset protection temperature, it is determined that there is no failed NTC temperature sensor, and the current temperature of the first NTC temperature sensor and the current temperatures of at least two second NTC temperature sensors continue to be collected; if the number of the third temperature and the multiple fourth temperatures that is greater than or equal to the second preset protection temperature is at least one, it is determined that there is a failed NTC temperature sensor.
[0102] For example, the second preset protection temperature can be set according to the first preset protection temperature and the actual situation of the electrical heating appliance, and the embodiment of the present application does not make any specific limitation on this.
[0103] In an embodiment of the present application, before determining a failed NTC temperature sensor, by comparing the third temperature and multiple fourth temperatures with the second preset protection temperature, it can be determined that there is a failed NTC temperature sensor only when at least one of the third temperature and the multiple fourth temperatures is greater than or equal to the second preset protection temperature. Then determining the failed NTC temperature sensor can avoid the detection of the failed NTC temperature sensor when there is no failed NTC temperature sensor occupying the storage space of the electromagnetic heating device, affecting the working condition of the electromagnetic heating device, and can effectively improve the efficiency of determining the failed NTC temperature sensor.
[0104] For example, when there is a failed NTC temperature sensor, the failed NTC temperature sensor can be determined from the first NTC temperature sensor and the second NTC temperature sensor according to the third temperature and multiple fourth temperatures. Specifically, the third temperature difference of the third temperature minus the first preset protection temperature, and the fourth temperature difference of each fourth temperature minus the first preset protection temperature can be determined; if the third temperature difference is greater than or equal to the third preset temperature difference, the first NTC temperature sensor is determined to be a failed NTC temperature sensor; if there is at least one fourth temperature difference greater than or equal to the third preset temperature difference, the second NTC temperature sensor corresponding to the fourth temperature difference greater than or equal to the third preset temperature difference is determined to be a failed NTC temperature sensor.
[0105] It can be understood that the first preset protection temperature can be 90 degrees Celsius or 95 degrees Celsius, and the third preset temperature difference can be 45 degrees Celsius or 50 degrees Celsius. The first preset protection temperature and the third preset temperature difference can be set according to the actual situation of the electromagnetic heating device, and the embodiment of the present application does not make specific limitations on this.
[0106] It can be understood that the embodiment of the present application determines the NTC temperature sensor corresponding to the temperature higher than the first preset protection temperature and reaching the third preset temperature difference as a failed NTC temperature sensor. For example, the first preset protection temperature is 92 degrees Celsius, and the third preset temperature difference is 45 degrees Celsius. When the temperature difference higher than 92 degrees Celsius reaches 45 degrees, the NTC temperature sensor corresponding to the temperature is determined to be a failed NTC temperature sensor.
[0107] In the embodiment of the present application, a failed NTC temperature sensor is determined among the first NTC temperature sensor and at least two second NTC temperature sensors according to the third temperature, multiple fourth temperatures, the first preset protection temperature and the third preset temperature difference. Since the detected third temperature and multiple fourth temperatures have high accuracy, the failed NTC temperature sensor can be accurately determined, thereby effectively avoiding the occurrence of accidents.
[0108] S303: If there is a failed NTC temperature sensor, output a warning message.
[0109] When outputting warning information, different warning information can be output according to different situations of the determined failed NTC temperature sensors. For example, if the failed NTC temperature sensor includes the first NTC temperature sensor and all the second NTC temperature sensors, the first warning information is output, and the first warning information is used to indicate that the electromagnetic heating device has exited the working state; if the failed NTC temperature sensor is the first NTC temperature sensor, the second warning information is output, and the second warning information is used to remind the user to move the device to be heated to the location where the second NTC temperature sensor is located; if the failed NTC temperature sensor includes at least one second NTC temperature sensor, the third warning information is output, and the third warning information is used to remind the user to move the device to be heated to the location where the first NTC temperature sensor is located or the location where the second NTC temperature sensor that has not failed is located.
[0110] It is understandable that the first warning information, the second warning information and the third warning information are all different and can be set according to the corresponding failed NTC temperature sensors, and the present application embodiment does not impose any limitation on this. For example, the first warning information can be set on the electromagnetic heating device to warn that when all NTC temperature sensors fail, the corresponding indicator light will display red, and the buzzer will beep 5 times to warn the user that all NTC temperature sensors have failed.
[0111] For example, the second warning information may be that when the NTC temperature sensor in the middle position set on the electromagnetic heating device fails, the corresponding indicator light displays red, and the buzzer emits 8 beeps to warn the user that the first NTC temperature sensor has failed, and prompt the user to move the two sides of the heating panel of the device to be heated.
[0112] For example, the third warning information may be that the indicator light at the position corresponding to the failed second NTC temperature sensor on the electromagnetic heating device is displayed in red, and the buzzer emits 10 beeps to warn the user that the second NTC temperature sensor at that position has failed, and prompt the user to move the device to be heated to the top of the NTC temperature sensor that has not failed, so as to facilitate the temperature detection. For example, if the first second NTC temperature sensor installed on the right side of the first NTC temperature sensor fails, the corresponding indicator light is displayed in red, and the buzzer emits 10 beeps to warn the user to move the device to be heated to the left to the position of the first NTC temperature sensor, or the second NTC temperature sensor that has not failed.
[0113] In the embodiment of the present application, by outputting corresponding warning information and prompting the user to perform corresponding operations, when the NTC sensor fails, the temperature of the electromagnetic heating device can still be accurately detected, which can effectively ensure the accuracy of the temperature detection of the electromagnetic heating device and the safety during use.
[0114] It can be seen that in the embodiment of the present application, when the duration of the electromagnetic heating device entering the working state reaches the second duration, the current third temperature of the first NTC temperature sensor and the current fourth temperature of at least two second NTC temperature sensors are collected, and the second duration is greater than the first duration; according to the third temperature and multiple fourth temperatures, the failed NTC temperature sensor is determined from the first NTC temperature sensor and the second NTC temperature sensor. The accuracy of the temperature detection of the electromagnetic heating device can be improved, so as to determine the bias of the device to be heated and the failure of the NTC temperature sensor, thereby avoiding accidents.
[0115] In order to facilitate understanding of the detection method of the electromagnetic heating device provided in the embodiment of the present application, the following will take the electromagnetic heating device as an induction cooker, and including two second NTC temperature sensors, as an example to describe the technical solution provided in the embodiment of the present application in detail. Figure 4 As shown, Figure 4 A schematic diagram of the structure of an NTC temperature sensor provided in an embodiment of the present application on an induction cooker. Figure 4 As shown, the first NTC temperature sensor is arranged in the middle of the heating panel, and the second NTC temperature sensor A and the second NTC temperature sensor B are arranged on both sides of the first NTC temperature sensor. The height setting of the first NTC temperature sensor can be referred to Figure 1 The height settings of NTC temperature sensor 1, the second NTC temperature sensor A and the second NTC temperature sensor B can be found in Figure 1 The configuration of the NTC temperature sensor 2 and the temperature sensor 3 will not be described in detail in the embodiments of the present application.
[0116] For example, using the above Figure 4 The structure shown in the figure, the technical solution provided by the embodiment of the present application can be found in Figure 5 As shown, Figure 5 A schematic diagram of a flow chart of another electromagnetic heating device detection method provided in an embodiment of the present application. Figure 5 As shown, the detection method of the electromagnetic heating device may include the following steps:
[0117] Step 1: Turn on the power.
[0118] For example, the user turns on the induction cooker by touching or clicking or pressing a physical button on the induction cooker. The present application embodiment is described by taking the above-mentioned power-on method as an example, but it does not mean that the present application embodiment is limited to this.
[0119] Step 2: After the user selects a function, the cooking state is entered, and the first NTC temperature sensor A and the second NTC temperature sensor B detect the temperature in real time.
[0120] For example, the user can select different functions according to their own needs to make the induction cooker enter the cooking working state. The embodiment of the present application does not impose any restrictions on the functions of the induction cooker. The first NTC temperature sensor, the second NTC temperature sensor A, and the second NTC temperature sensor B perform real-time temperature detection, which can be seen in the above embodiment, and the embodiment of the present application will not be repeated here.
[0121] Step 3: The working time reaches 1 minute.
[0122] Step 4: Determine whether all NTC temperature sensors are greater than the ambient temperature of 25°C.
[0123] For example, if all NTC temperature sensors are greater than the ambient temperature of 25°C, it means that all NTC temperature sensors are in normal state, and step 5 is performed. If there is an NTC temperature sensor whose ambient temperature is less than 25°C among all NTC temperature sensors, it means that there is an abnormal NTC temperature sensor, and step 21 is performed.
[0124] Step 5: The working time reaches 5 minutes.
[0125] Step 6: Determine whether the pot is offset.
[0126] For example, if the temperature collected by the first NTC temperature sensor is lower than the temperature collected by any second NTC temperature sensor, the cookware is determined to be biased. If the temperature collected by the first NTC temperature sensor is higher than the temperatures collected by all second NTC temperature sensors, and the temperature difference between the temperatures collected by the second NTC temperature sensor A and the second NTC temperature sensor B is greater than or equal to 30°C, then step 7 is performed. If the temperature collected by the first NTC temperature sensor is higher than the temperature collected by any second NTC temperature sensor, and the temperature difference between the temperatures collected by the second NTC temperature sensor A and the second NTC temperature sensor B is less than 30°C, it means that the cookware is not biased, and step 8 is performed.
[0127] Step 7: The pot is offset, the buzzer beeps 5 times, and the user performs the pot moving operation.
[0128] For example, when the pot is offset, a buzzer sound is emitted to prompt the user to move the pot so that the pot is in the center of the heating panel.
[0129] Step 8: The working time reaches 10 minutes.
[0130] Step 9: Determine whether the temperature collected by at least one NTC temperature sensor reaches the protection value.
[0131] For example, if the temperature collected by at least one NTC temperature sensor reaches the protection value, it indicates that there is a failed NTC temperature sensor, and step 11 is executed, otherwise step 10 is executed. It can be understood that the protection value corresponds to the second preset protection temperature in the above embodiment, and the embodiment of the present application does not specifically limit this.
[0132] Step 10: Continue testing.
[0133] For example, when the temperature continues to be detected, step 9 may be performed at fixed intervals, that is, determining whether the temperature collected by at least one NTC temperature sensor reaches a protection value to ensure that the induction cooker can operate normally.
[0134] Step 11: Determine whether all NTC temperature sensors are invalid.
[0135] For example, when determining whether all NTC temperature sensors have failed, the detected temperature of each NTC temperature sensor can be compared with the final protection point, and the final protection point is the first preset protection temperature in the above embodiment. For details, please refer to the above embodiment. If all NTC temperature sensors have failed, execute steps 19-20. If all NTC temperature sensors have not failed, execute steps 12-14 or steps 15-17.
[0136] Step 12: The temperature detected by the first NTC temperature sensor is higher than the final protection point of 45° C., and the temperature detected by the second NTC temperature sensor A and the temperature detected by the second NTC temperature sensor B are both lower than the final protection point of 45° C.
[0137] Step 13: The first NTC temperature sensor fails.
[0138] Step 14: The buzzer beeps 6 times.
[0139] For example, the buzzer sounds to prompt the user to perform the operation of moving the pot. After the pot is moved, the following step 18 can be performed.
[0140] Step 15: The temperature detected by the first NTC temperature sensor is 45° C. lower than the final protection point, and there is at least one second NTC temperature sensor that is 45° C. higher than the final protection point.
[0141] Step 16: When the detected temperature is 45° C. higher than the final protection point, the corresponding second NTC temperature sensor fails.
[0142] Step 17: The buzzer beeps 4 or 8 times.
[0143] It is understandable that when different second NTC temperature sensors fail, the number of buzzer beeps is different, and the embodiment of the present application does not specifically limit this.
[0144] For example, the buzzer sounds to prompt the user to perform the operation of moving the pot. After the pot is moved, the following step 18 can be performed.
[0145] Step 18: After detecting that the user has adjusted the placement position of the appliance to be heated, the induction cooker operates normally.
[0146] For example, during the normal induction process, if a command input by a user for instructing the induction cooker to stop working is received, the induction cooker exits the working state, that is, step 21 is executed.
[0147] Step 19: The detected temperatures of all NTC temperature sensors are higher than the final protection point of 45°C.
[0148] Step 20: The buzzer beeps 10 times.
[0149] Step 21: Exit working state.
[0150] In summary, the detection method of electromagnetic heating appliances provided in the embodiment of the present application is easy to install, easy to disassemble and assemble, has low radiation interference, can detect whether the pot is biased through the NTC temperature detector, and alarm to remind users to put the pot straight when the pot is biased. In addition, when the first NTC temperature sensor for precise temperature measurement fails, the second NTC temperature sensor of the ordinary temperature measurement device can be used for temperature detection, avoiding the problem of accidents caused by failure to detect temperature. Temperature detection and comparison by multiple NTC temperature sensors can effectively avoid fires caused by excessive temperature.
