[0045] To make the features and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.
[0046] The existing dry-burn detection method is to set a temperature sensor in the burner of the stove and contact it with the bottom of the pot. The temperature sensor then obtains the bottom temperature of the pot and determines that the pot is in a dry-burn state when the bottom temperature reaches the dry-burn temperature threshold.
[0047] When the burner is at a high power, part of the flame generated by the burner will transfer to the surrounding area after it contacts the bottom of the pot, causing the transferred flame to burn towards the temperature sensor, resulting in the temperature sensed by the temperature sensor being too high, and it is impossible to obtain an accurate dry burning detection result.
[0048] To improve the accuracy of dry-burn detection, please refer to Figure 1 , is a device architecture diagram of a dry burning detection device provided in an embodiment of this specification.
[0049] like Figure 1 As shown, the dry burning detection device 10 includes a control unit 11, a stove 12 and a temperature sensor 13. The temperature sensor 13 is arranged in the burner of the stove 12 and contacts the bottom of the pot 20. For details, see Figure 2 , Figure 2 A schematic structural diagram of a dry-boiling detection device 10 and a cookware 20 is provided.
[0050] The control unit 11 is used to turn on or off the stove 12 and can also control the fire power of the stove 12. The temperature sensor 13 is used to obtain the bottom temperature of the pot 20 located directly above the burner of the stove 12.
[0051] The control unit 11 continuously monitors the first temperature of the cookware 20 via the temperature sensor 13. It is understood that the control unit 11 continuously receives the first temperature of the cookware 20 transmitted by the temperature sensor 13. After obtaining the first temperature of the cookware 20, the control unit 11 compares the first temperature with the dry-boil temperature threshold. Based on the comparison result that the first temperature is greater than or equal to the dry-boil temperature threshold, the control unit 11 generates a power reduction instruction and then transmits the power reduction instruction to the stove 12. In response to the received power reduction instruction, the stove 12 reduces the power of the burner. After transmitting the power reduction instruction, the control unit 11 begins timing. After the timing reaches a set duration, the control unit 11 controls the temperature sensor 13 to obtain the second temperature of the cookware 20. The control unit then compares the second temperature with the dry-boil temperature threshold. Based on the comparison result that the second temperature is greater than or equal to the dry-boil temperature threshold, the control unit 11 determines that the cookware 20 is in a dry-boil state.
[0052] When generating a power reduction instruction, the control unit 11 may generate a first power reduction instruction to reduce the power of the cooker 12 to a set power. In response to the received first power reduction instruction, the cooker 12 reduces the power of its burner to the set power. Furthermore, based on the detection result that the cooker 20 is in a dry-burn state, the control unit 11 generates a dry-burn processing instruction to shut down the cooker 12. In response to the dry-burn processing instruction, the cooker 12 shuts down its burner. Based on the detection result that the cooker 20 is in a dry-burn state, the control unit 11 may also generate a warning message indicating that the cooker 20 is in a dry-burn state and output the warning message via the output device of the dry-burn detection device 10.
[0053] When generating the power reduction instruction, the control unit 11 may generate a second power reduction instruction to shut down the cooker 12. In response to the received second power reduction instruction, the cooker 12 shuts down its burner. Based on the detection result that the cooker 20 is in a dry-boil state, the control unit 11 generates a warning message indicating that the cooker 20 is in a dry-boil state and outputs it via the output device of the dry-boil detection device 10.
[0054] The control unit 11 generates a power restoration instruction based on the comparison result that the second temperature is lower than the dry-boiling temperature threshold, and then sends the power restoration instruction to the cooker 12. The cooker 12 restores the power of the burner in response to the power restoration instruction.
[0055] Before sending the power reduction instruction to the cooker 12, the control unit 11 may obtain the current target power of the cooker 12, and then determine that the pot 20 is not in a dry-boil state based on the comparison result that the second temperature is less than the dry-boil temperature threshold. Then, the control unit 11 generates a power restoration instruction to restore the power to the target power, and then sends the power restoration instruction to the cooker 12. In response to the power restoration instruction, the cooker 12 restores the power of the burner to the target power.
[0056] The following will be combined Figure 3-Figure 7 , the dry burning detection method provided in the embodiments of the present application is introduced in detail.
[0057] See Figure 3 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 3 As shown, the method may include the following steps S101 to S104.
[0058] S101, obtaining a first temperature of the cookware.
[0059] In one implementation, a pot refers to various utensils for cooking food or boiling water. Specifically, in this embodiment, a pot is defined as an appliance that uses external heating for cooking or boiling water, such as an iron pot, a non-stick pan, a clay pot, a soup pot, etc., and an appliance that can directly contact the open flame generated by a stove.
[0060] The dry-boiling detection device obtains the temperature currently sensed by the temperature sensor and uses the temperature as the first temperature of the cookware.
[0061] It should be noted that the bottom of the pot is in contact with the temperature sensor, which is located in the burner of the stove. For example, the temperature sensor is located in the center of the burner and is higher than the burner. Furthermore, the material supporting the temperature sensor is elastic. When the pot is placed on the burner of the stove, the downward pressure of the pot will cause it to make close contact with the temperature sensor without damaging the temperature sensor.
[0062] S102: Based on a comparison result that the first temperature is greater than or equal to a dry-boiling temperature threshold, reduce the firepower of the stove corresponding to the pot.
[0063] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0064] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0065] After obtaining the first temperature of the cookware, the dry-burn detection device compares the first temperature with a dry-burn temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-burn temperature threshold. When the first temperature is greater than or equal to the dry-burn temperature threshold, the dry-burn detection device determines the cookware corresponding to the cookware having the first temperature greater than or equal to the dry-burn temperature threshold. Specifically, the dry-burn detection device can determine the cookware corresponding to the cookware based on the temperature sensor that obtains the first temperature, then generate a control instruction for reducing the heat of the cookware, i.e., a heat reduction instruction, and then send the control instruction (heat reduction instruction) to the cookware, so that the cookware reduces the heat of the cookware, i.e., reduces the size of the flame generated by the burner on the cookware, in response to the received control instruction (heat reduction instruction).
[0066] S103, after the set time period, obtaining the second temperature of the cookware.
[0067] In one implementation, the set time length is the time length required for the temperature sensor to return to normal detection conditions. Specifically, the temperature sensor is originally continuously burned by the flame generated by the burner. When the flame generated by the burner stops burning the temperature sensor, it is necessary to wait for a first time length so that the pot temperature sensed by the temperature sensor will not be disturbed by the flame generated by the burner. If the waiting time length exceeds the second time length, the temperature of the pot will drop due to the decrease in the firepower of the stove. At this time, the temperature sensed by the temperature sensor is also inaccurate. Therefore, the set time length is any time length that is greater than or equal to the first time length and less than the second time length. Among them, the first time length and the second time length are both empirical values, which can be inferred through multiple dry burning detection processes and are not limited here.
[0068] After sending a firepower reduction instruction to the cooker, the dry burning detection device starts timing, and after the timing reaches the set time, obtains the temperature currently sensed by the temperature sensor and uses the temperature as the second temperature of the cooker.
[0069] S104: Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0070] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is in a dry-boil state when the second temperature is greater than or equal to the dry-boil temperature threshold.
[0071] In the embodiment of the present application, by reducing the fire power of the stove and lowering the height of the flame generated by the burner in the stove, the flame generated by the burner will not move to the surroundings after contacting the bottom of the pot due to being too high, thereby avoiding the flame burning directly at the temperature sensor and reducing the impact of the flame on the temperature sensor. At the same time, by re-acquiring the second temperature of the pot after a set time, the impact of the flame on the temperature sensor is also reduced. By improving the accuracy of the temperature sensor, the accuracy of the dry burning detection result is improved.
[0072] It is understandable that there are many ways to reduce the firepower of the stove in the dry burning detection device. Figure 4-Figure 5 , a detailed introduction is given to the dry burning detection methods corresponding to different ways of reducing firepower.
[0073] See Figure 4 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 4 As shown, the method may include the following steps S201 to S206.
[0074] S201, obtaining a first temperature of the cookware.
[0075] In one implementation, a pot refers to various utensils for cooking food or boiling water. Specifically, in this embodiment, a pot is defined as an appliance that uses external heating for cooking or boiling water, such as an iron pot, a non-stick pan, a clay pot, a soup pot, etc., and an appliance that can directly contact the open flame generated by a stove.
[0076] The dry-boiling detection device obtains the temperature currently sensed by the temperature sensor and uses the temperature as the first temperature of the cookware.
[0077] It should be noted that the bottom of the pot is in contact with the temperature sensor, which is located in the burner of the stove. For example, the temperature sensor is located in the center of the burner and is higher than the burner. Furthermore, the material supporting the temperature sensor is elastic. When the pot is placed on the burner of the stove, the downward pressure of the pot will cause it to make close contact with the temperature sensor without damaging the temperature sensor.
[0078] S202, based on the comparison result that the first temperature is greater than or equal to the dry-burning temperature threshold, reducing the firepower of the stove corresponding to the pot to a set firepower, and the flame height corresponding to the set firepower is less than the height of a temperature sensor, and the temperature sensor is arranged in the burner of the stove and in contact with the bottom of the pot of the pot, and is used to obtain the temperature of the pot.
[0079] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0080] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0081] The flame height corresponding to the set firepower is less than the height of the temperature sensor. It is understandable that the firepower is proportional to the flame height. The greater the firepower, the higher the flame height. The set firepower is calculated based on the height of the temperature sensor.
[0082] After obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with the dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the cooktop corresponding to the cookware having the first temperature greater than or equal to the dry-boil temperature threshold. Specifically, the cooktop corresponding to the cookware can be determined based on the temperature sensor that obtained the first temperature.
[0083] The dry-burn detection device generates a first firepower reduction instruction for reducing the firepower of the stove to the set firepower based on the set firepower, and then sends the first firepower reduction instruction to the stove, so that the stove responds to the received first firepower reduction instruction and reduces the firepower of the stove to the set firepower, thereby reducing the size of the flame generated by the burner on the stove so that the height of the flame generated by the burner is smaller than the height of the temperature sensor.
[0084] By reducing the stove's firepower to the set firepower and lowering the flame height to below the height of the temperature sensor, the flame is prevented from burning directly towards the temperature sensor and the impact of the flame on the temperature sensor is reduced, thereby improving the accuracy of dry-burn detection results. At the same time, because the stove's firepower is only reduced to the set firepower, the pot can be guaranteed to cook normally when it is not determined that the pot is in a dry-burn state.
[0085] S203: After the set time period, obtain the second temperature of the cookware.
[0086] In one implementation, the set time length is the time length required for the temperature sensor to return to normal detection conditions. Specifically, the temperature sensor is originally continuously burned by the flame generated by the burner. When the flame generated by the burner stops burning the temperature sensor, it is necessary to wait for a first time length so that the pot temperature sensed by the temperature sensor will not be disturbed by the flame generated by the burner. If the waiting time length exceeds the second time length, the temperature of the pot will drop due to the decrease in the firepower of the stove. At this time, the temperature sensed by the temperature sensor is also inaccurate. Therefore, the set time length is any time length that is greater than or equal to the first time length and less than the second time length. Among them, the first time length and the second time length are both empirical values, which can be inferred through multiple dry burning detection processes and are not limited here.
[0087] After sending a firepower reduction instruction to the cooker, the dry burning detection device starts timing, and after the timing reaches the set time, obtains the temperature currently sensed by the temperature sensor and uses the temperature as the second temperature of the cooker.
[0088] S204: Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0089] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is in a dry-boil state when the second temperature is greater than or equal to the dry-boil temperature threshold.
[0090] S205: Turn off the stove corresponding to the pot.
[0091] In one implementation, when the dry-boil detection device determines that the cookware is in a dry-boil state, it generates a stove-off instruction for shutting down the cooker, and then sends the stove-off instruction to the cooker corresponding to the cookware. In response to the stove-off instruction, the cooker shuts down the burner, causing the burner to stop producing flames and, in turn, to stop heating the cookware.
[0092] By turning off the stove corresponding to the cookware when the cookware is in a dry-burning state, the stove stops heating the cookware, thereby avoiding safety problems caused by continuously heating the cookware in a dry-burning state, and improving the safety of the dry-burning detection device and the cookware.
[0093] S206: Outputting a warning message indicating that the cookware is in a dry-boil state.
[0094] In one implementation, when the dry-boiling detection device determines that the cookware is in a dry-boiling state, it generates a warning message for warning that the cookware is in a dry-boiling state, and outputs the warning message through the output device.
[0095] It is understood that different warning messages require different output devices. For example, when the warning message is a text or image prompt, the output device may be a display device on the dry-boil detection device; when the warning message is a buzzer, the output device may be a buzzer; when the warning message is an audible prompt, the output device may be an audio playback device, etc. The warning message may also be transmitted to an electronic device corresponding to the dry-boil detection device via an output interface, without limitation.
[0096] By outputting a warning message when the cookware is in a dry-burning state, the user / operator is warned that the cookware is in a dry-burning state and there is a safety hazard, so that the user can deal with it as soon as possible, thereby improving the safety of the dry-burning detection device and the cookware.
[0097] In the embodiment of the present application, by reducing the firepower of the stove to the set firepower and lowering the flame height to below the height of the temperature sensor, the situation where the flame burns directly towards the temperature sensor is avoided, and the influence of the flame on the temperature sensor is reduced, thereby improving the accuracy of the dry-burn detection result; at the same time, because the firepower of the stove is only reduced to the set firepower, normal cooking operation is guaranteed when it is not determined that the pot is in a dry-burn state; by turning off the stove corresponding to the pot when the pot is in a dry-burn state, the stove stops heating the pot, avoiding safety problems caused by continuous heating of the pot in a dry-burn state, thereby improving the safety of the dry-burn detection device and the pot; by outputting a warning message when the pot is in a dry-burn state to warn the user / operator that the pot is in a dry-burn state and there is a safety hazard, the user is prompted to deal with it as soon as possible, thereby improving the safety of the dry-burn detection device and the pot.
[0098] See Figure 5 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 5 As shown, the method may include the following steps S301-S305.
[0099] S301, obtaining a first temperature of the cookware.
[0100] Please refer to step S201 for details, which will not be repeated here.
[0101] S302: Based on a comparison result that the first temperature is greater than or equal to a dry-boiling temperature threshold, turning off the stove corresponding to the pot.
[0102] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0103] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0104] After obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with the dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the cooktop corresponding to the cookware having the first temperature greater than or equal to the dry-boil temperature threshold. Specifically, the cooktop corresponding to the cookware can be determined based on the temperature sensor that obtained the first temperature.
[0105] The dry burning detection device generates a second firepower reduction instruction for shutting down the stove, and then sends the second firepower reduction instruction to the stove, so that the stove responds to the received second firepower reduction instruction and shuts down the burner of the stove, so that the burner stops generating flame.
[0106] By turning off the stove, the burner stops generating flames, which prevents the flame from burning directly at the temperature sensor and reduces the impact of the flame on the temperature sensor, thereby improving the accuracy of dry burning detection results.
[0107] S303: After the set time period, obtain the second temperature of the cookware.
[0108] Please refer to step S203 for details, which will not be repeated here.
[0109] S304: Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0110] Please refer to step S204 for details, which will not be described again here.
[0111] S305: Outputting a warning message indicating that the cookware is in a dry-boil state.
[0112] For details, please refer to step S205, which will not be repeated here.
[0113] By outputting a warning message when the cookware is in a dry-burning state, the user / operator is warned that the cookware is in a dry-burning state and there is a safety hazard, so that the user can deal with it as soon as possible, thereby improving the safety of the dry-burning detection device and the cookware.
[0114] In the embodiment of the present application, by turning off the cooker, the burner stops generating flames, thereby avoiding the situation where the flame burns directly towards the temperature sensor and reducing the impact of the flame on the temperature sensor, thereby improving the accuracy of the dry-burn detection results; by outputting a warning message when the cookware is in a dry-burn state, the user / operator is warned that the cookware is in a dry-burn state and there is a safety hazard, so that the user can deal with it as soon as possible, thereby improving the safety of the dry-burn detection device and the cookware.
[0115] It is understandable that there are many ways to control the stove to ensure the normal operation of the cooking process. Figure 6-Figure 7 , a detailed introduction is given to the dry-burn detection methods corresponding to different stove control methods.
[0116] See Figure 6 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 6 As shown, the method may include the following steps S401 to S406.
[0117] S401: Obtain a first temperature of the cookware.
[0118] In one implementation, a pot refers to various utensils for cooking food or boiling water. Specifically, in this embodiment, a pot is defined as an appliance that uses external heating for cooking or boiling water, such as an iron pot, a non-stick pan, a clay pot, a soup pot, etc., and an appliance that can directly contact the open flame generated by a stove.
[0119] The dry-boiling detection device obtains the temperature currently sensed by the temperature sensor and uses the temperature as the first temperature of the cookware.
[0120] It should be noted that the bottom of the pot is in contact with the temperature sensor, which is located in the burner of the stove. For example, the temperature sensor is located in the center of the burner and is higher than the burner. Furthermore, the material supporting the temperature sensor is elastic. When the pot is placed on the burner of the stove, the downward pressure of the pot will cause it to make close contact with the temperature sensor without damaging the temperature sensor.
[0121] S402: Based on a comparison result that the first temperature is greater than or equal to a dry-boiling temperature threshold, reduce the firepower of the stove corresponding to the pot.
[0122] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0123] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0124] After obtaining the first temperature of the cookware, the dry-burn detection device compares the first temperature with a dry-burn temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-burn temperature threshold. When the first temperature is greater than or equal to the dry-burn temperature threshold, the dry-burn detection device determines the cookware corresponding to the cookware having the first temperature greater than or equal to the dry-burn temperature threshold. Specifically, the dry-burn detection device can determine the cookware corresponding to the cookware based on the temperature sensor that obtains the first temperature, then generate a control instruction for reducing the heat of the cookware, i.e., a heat reduction instruction, and then send the control instruction (heat reduction instruction) to the cookware, so that the cookware reduces the heat of the cookware, i.e., reduces the size of the flame generated by the burner on the cookware, in response to the received control instruction (heat reduction instruction).
[0125] S403: After the set time, obtain the second temperature of the cookware.
[0126] In one implementation, the set time length is the time length required for the temperature sensor to return to normal detection conditions. Specifically, the temperature sensor is originally continuously burned by the flame generated by the burner. When the flame generated by the burner stops burning the temperature sensor, it is necessary to wait for a first time length so that the pot temperature sensed by the temperature sensor will not be disturbed by the flame generated by the burner. If the waiting time length exceeds the second time length, the temperature of the pot will drop due to the decrease in the firepower of the stove. At this time, the temperature sensed by the temperature sensor is also inaccurate. Therefore, the set time length is any time length that is greater than or equal to the first time length and less than the second time length. Among them, the first time length and the second time length are both empirical values, which can be inferred through multiple dry burning detection processes and are not limited here.
[0127] After sending a firepower reduction instruction to the cooker, the dry burning detection device starts timing, and after the timing reaches the set time, obtains the temperature currently sensed by the temperature sensor and uses the temperature as the second temperature of the cooker.
[0128] S404: Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0129] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is in a dry-boil state when the second temperature is greater than or equal to the dry-boil temperature threshold.
[0130] S405: Based on the comparison result that the second temperature is lower than the dry-boiling temperature threshold, it is determined that the cookware is not in a dry-boiling state, and the fire power of the stove corresponding to the cookware is restored.
[0131] In one implementation, after obtaining the second temperature of the cookware, the dry-burn detection device compares the second temperature with a dry-burn temperature threshold to determine the magnitude relationship between the second temperature threshold and the dry-burn temperature threshold. When the second temperature is less than the dry-burn temperature threshold, the dry-burn detection device determines that the cookware is not in a dry-burn state. After determining that the cookware is not in a dry-burn state, the dry-burn detection device generates a firepower restoration instruction for restoring the stove's firepower, and then sends the firepower restoration instruction to the stove. In response to the received firepower restoration instruction, the stove restores the burner's firepower. It is understandable that if the burner is in the off state, the stove needs to first turn on the burner and then increase the burner's firepower.
[0132] In the embodiment of the present application, the firepower of the stove is restored when the pot is not in a dry-burning state, thereby ensuring that the pot can cook normally.
[0133] See Figure 7, provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 7 As shown, the method may include the following steps S501 to S506.
[0134] S501: Obtain a first temperature of the cookware.
[0135] Please refer to step S401 for details, which will not be repeated here.
[0136] S502: Based on a comparison result that the first temperature is greater than or equal to a dry-boiling temperature threshold, obtain a target firepower of a stove corresponding to the pot.
[0137] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0138] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0139] After acquiring the first temperature of the cookware, the dry-boil detection device compares the first temperature with a dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the cooktop corresponding to the cookware having the first temperature greater than or equal to the dry-boil temperature threshold. Specifically, the cooktop corresponding to the cookware can be determined based on the temperature sensor that acquired the first temperature, and then the current heat level of the cooktop can be determined, which can then be used as the target heat level for the cooktop corresponding to the cookware.
[0140] S503: Reduce the firepower of the stove corresponding to the pot.
[0141] In one implementation, the dry burn detection device generates a control instruction for reducing the firepower of the stove, i.e., a firepower reduction instruction, and then sends the control instruction (firepower reduction instruction) to the stove, so that the stove reduces the firepower of the stove in response to the received control instruction (firepower reduction instruction), i.e., reduces the size of the flame generated by the burner on the stove.
[0142] S504: After the set time period, obtain the second temperature of the cookware.
[0143] Please refer to step S403 for details, which will not be described again here.
[0144] S505 : Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0145] Please refer to step S404 for details, which will not be repeated here.
[0146] S506: Based on the comparison result that the second temperature is lower than the dry-boiling temperature threshold, it is determined that the cookware is not in a dry-boiling state, and the heat of the stove corresponding to the cookware is restored to the target heat.
[0147] In one implementation, after obtaining the second temperature of the cookware, the dry-burn detection device compares the second temperature with a dry-burn temperature threshold to determine the magnitude relationship between the second temperature threshold and the dry-burn temperature threshold. When the second temperature is less than the dry-burn temperature threshold, the dry-burn detection device determines that the cookware is not in a dry-burn state. After determining that the cookware is not in a dry-burn state, the dry-burn detection device generates a firepower restoration instruction for restoring the cooker's firepower to the target firepower based on the cooker's target firepower. The firepower restoration instruction carries the target firepower and then sends the firepower restoration instruction to the cooker. In response to the received firepower restoration instruction, the cooker restores the burner's firepower to the target firepower. It will be understood that if the burner is in the off state, the cooker needs to first turn on the burner and then increase the burner's firepower to the target firepower.
[0148] In an embodiment of the present application, the firepower of the stove is restored when the pot is not in a dry-burn state, thereby ensuring that the pot can cook normally, and by restoring the firepower to the target, the impact of the dry-burn detection process on the cooking process is reduced.
[0149] The existing dry-burn detection method is to set a temperature sensor in the burner of the stove and contact it with the bottom of the pot. The temperature sensor then obtains the bottom temperature of the pot and determines that the pot is in a dry-burn state when the bottom temperature reaches the dry-burn temperature threshold.
[0150] If the cooker has a corresponding fan (such as a range hood, exhaust fan, etc.), when the fan is started, the wind force generated will cause the flame to shift, causing the shifted flame to burn towards the temperature sensor, resulting in the temperature sensed by the temperature sensor being too high, and an accurate dry burning detection result cannot be obtained.
[0151] To improve the accuracy of dry-burn detection, see Figure 8 , is a device architecture diagram of a dry burning detection device provided in an embodiment of this specification.
[0152] like Figure 8 As shown, the dry burning detection device 10 includes a control unit 11, a stove 12, a temperature sensor 13 and a fan 14. The temperature sensor 13 is set in the burner of the stove 12 and contacts the bottom of the pot 20. For details, see Figure 2 , Figure 2 A schematic diagram of the structure between the dry-boiling detection device 10 and the cookware 20 is provided. The fan 14 can be installed directly above the cooker 12 or to the side of the cooker 12. This embodiment does not limit the specific installation position of the fan 14. Specifically, the fan 14 can be installed in any direction of the cooker 12.
[0153] Control unit 11 is used to turn cooker 12 on and off. It also turns fan 14 on and off. Temperature sensor 13 is used to detect the bottom temperature of pot 20, located directly above the burner of cooker 12. Fan 14 is used to create a negative pressure zone within a certain area around cooker 12 (i.e., where fan 14 is installed). This draws cooking fumes from the indoor environment into fan 14 and blows them out to the outdoor environment.
[0154] The control unit 11 continuously monitors the first temperature of the pot 20 through the temperature sensor 13. It is understandable that the control unit 11 continuously receives the first temperature of the pot 20 sent by the temperature sensor 13. After obtaining the first temperature of the pot 20, the control unit 11 compares the first temperature with the dry-boiling temperature threshold, and then generates a fan-off instruction based on the comparison result that the first temperature is greater than or equal to the dry-boiling temperature threshold, and then sends a fan-on or fan-off instruction to the fan 14. The fan 14 turns off the fan in response to the received fan-off instruction. After sending the fan-off instruction, the control unit 11 starts timing, and after the timing reaches the set time, controls the temperature sensor 13 to obtain the second temperature of the pot 20, and then compares the second temperature with the dry-boiling temperature threshold. Then, based on the comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold, it determines that the pot 20 is in a dry-boiling state.
[0155] Based on the detection result of the cookware 20 processing the dry-boil state, the control unit 11 generates a warning message indicating that the cookware 20 is in a dry-boil state, and outputs the warning message through the output device of the dry-boil detection device 10. The control unit 11 may also generate a stove-off instruction based on the detection result of the cookware 20 processing the dry-boil state, and then transmit the stove-off instruction to the stove 12. The stove 12 responds to the received stove-off instruction and turns off the burner.
[0156] The control unit 11 determines that the cookware 20 is not in a dry-boil state based on the comparison result that the second temperature is less than the dry-boil temperature threshold, and then generates a fan-on instruction and sends the fan-on instruction to the fan 14. The fan 14 turns on the fan in response to the fan-on instruction.
[0157] The following will be combined Figure 9-10 , the dry burning detection method provided in the embodiments of the present application is introduced in detail.
[0158] See Figure 9 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 9 As shown, the method may include the following steps S601 to S604.
[0159] S601: Obtain a first temperature of the cookware.
[0160] In one implementation, a pot refers to various utensils for cooking food or boiling water. Specifically, in this embodiment, a pot is defined as an appliance that uses external heating for cooking or boiling water, such as an iron pot, a non-stick pan, a clay pot, a soup pot, etc., and an appliance that can directly contact the open flame generated by a stove.
[0161] The dry-boiling detection device obtains the temperature currently sensed by the temperature sensor and uses the temperature as the first temperature of the cookware.
[0162] It should be noted that the bottom of the pot is in contact with the temperature sensor, which is located in the burner of the stove. For example, the temperature sensor is located in the center of the burner and is higher than the burner. Furthermore, the material supporting the temperature sensor is elastic. When the pot is placed on the burner of the stove, the downward pressure of the pot will cause it to make close contact with the temperature sensor without damaging the temperature sensor.
[0163] S602: Based on the comparison result that the first temperature is greater than or equal to the dry-boiling temperature threshold, reduce the rotation speed of the fan corresponding to the cookware.
[0164] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0165] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0166] After obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with the dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the fan corresponding to the cookware whose first temperature is greater than or equal to the dry-boil temperature threshold, then generates a control instruction for reducing the speed of the fan, i.e., a speed reduction instruction, and then sends the control instruction (speed reduction instruction) to the fan, causing the fan to reduce its speed in response to the received control instruction (speed reduction instruction), thereby reducing the wind force generated by the fan.
[0167] S603: After the set time, obtain the second temperature of the cookware.
[0168] In one implementation, the set time length is the time length required for the temperature sensor to return to normal detection conditions. Specifically, the temperature sensor is originally continuously burned by the flame generated by the burner. When the flame generated by the burner stops burning the temperature sensor, it is necessary to wait for a first time length so that the pot temperature sensed by the temperature sensor will not be disturbed by the flame generated by the burner. If the waiting time length exceeds the second time length, the temperature of the pot will drop due to the decrease in the firepower of the stove. At this time, the temperature sensed by the temperature sensor is also inaccurate. Therefore, the set time length is any time length that is greater than or equal to the first time length and less than the second time length. Among them, the first time length and the second time length are both empirical values, which can be inferred through multiple dry burning detection processes and are not limited here.
[0169] After sending a firepower reduction instruction to the cooker, the dry burning detection device starts timing, and after the timing reaches the set time, obtains the temperature currently sensed by the temperature sensor and uses the temperature as the second temperature of the cooker.
[0170] S604: Determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0171] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is in a dry-boil state when the second temperature is greater than or equal to the dry-boil temperature threshold.
[0172] In an embodiment of the present application, the rotation speed of the fan around the stove is reduced, thereby reducing the wind force generated by the fan, and further reducing the impact of the fan on the flame generated by the stove, so that the flame is reduced in deviation or stops deviating, so as to avoid the flame burning directly at the temperature sensor, thereby reducing the impact of the flame on the temperature sensor. At the same time, by re-obtaining the second temperature of the pot after a set time, the impact of the flame on the temperature sensor is also reduced. By improving the accuracy of the temperature sensor, the accuracy of the dry burning detection result is improved.
[0173] See Figure 10 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 10 As shown, the method may include the following steps S701 to S707.
[0174] S701: Obtain a first temperature of the cookware.
[0175] Please refer to step S601 for details, which will not be repeated here.
[0176] S702, based on the comparison result that the first temperature is greater than or equal to the dry-burning temperature threshold, the speed of the fan corresponding to the cookware is reduced to a set speed, the set speed indicating that the distance between the flame generated by the stove and the temperature sensor is greater than the set distance, the temperature sensor is arranged in the burner of the stove and is in contact with the bottom of the cookware, and is used to obtain the temperature of the cookware.
[0177] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0178] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0179] The set speed indicates that the distance between the stove flame and the temperature sensor is greater than the set distance. Specifically, because a higher fan speed generates greater wind force, the flame on the stove shifts further, bringing the flame closer and closer to the temperature sensor located on the stove burner. Therefore, the set speed indicates that the wind force generated by the fan causes the stove flame to shift, and the distance between the flame and the temperature sensor is greater than the set distance. It should be noted that the set distance is the minimum distance at which the flame will not affect the temperature sensor's detection results. Specifically, when the distance between the flame and the temperature sensor is less than or equal to the set distance, the flame will affect the temperature sensor's detection results.
[0180] After obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with the dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the fan corresponding to the cookware having the first temperature greater than or equal to the dry-boil temperature threshold.
[0181] The dry burn detection device generates a first speed reduction instruction for reducing the speed of the fan to the set speed based on the set speed, and then sends the first speed reduction instruction to the fan, so that the fan responds to the received first speed reduction instruction and reduces the speed of the fan to the set speed, thereby reducing the wind force generated by the fan. It can be understood that the wind force generated by the fan is reduced to the set wind force so that the flame generated by the burner will not be less than or equal to the set distance between the flame and the temperature sensor due to the wind force generated by the fan.
[0182] By reducing the fan speed to the set speed, the wind force generated by the fan is reduced to the set wind force, and the distance between the flame and the temperature sensor is increased to above the set distance. This not only avoids the flame burning directly towards the temperature sensor, but also reduces the impact of the flame on the temperature sensor, thereby improving the accuracy of the dry burning detection result; at the same time, because the fan speed is only reduced to the set speed, it ensures that the oil smoke generated by the cookware can be discharged normally.
[0183] S703: Based on the comparison result that the first temperature is greater than or equal to the dry-boiling temperature threshold, turn off the fan corresponding to the cookware.
[0184] In one implementation, after obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with a dry-boil temperature threshold to determine a magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the fan corresponding to the cookware having the first temperature greater than or equal to the dry-boil temperature threshold.
[0185] The dry burn detection device generates a second speed reduction instruction for turning off the fan, and then sends the second speed reduction instruction to the fan, so that the fan responds to the received second speed reduction instruction and turns off the fan, so that the fan directly stops generating wind power. It can be understood that when the fan no longer generates wind power, the flame generated by the burner will no longer be offset by the wind power generated by the fan, thereby making the distance between the flame and the temperature sensor less than or equal to the set distance.
[0186] By turning off the fan corresponding to the cooker, the fan no longer generates wind that affects the flame, so that the flame generated by the stove no longer deviates, and the distance between the flame and the temperature sensor is increased to above the set distance. This not only avoids the flame burning directly at the temperature sensor, but also reduces the impact of the flame on the temperature sensor, thereby improving the accuracy of the dry burning detection results.
[0187] S704: After the set time, obtain the second temperature of the cookware.
[0188] Please refer to step S603 for details, which will not be repeated here.
[0189] S705: Restore the rotation speed of the fan corresponding to the cookware.
[0190] In one implementation, after the dry-burn detection device reacquires the temperature of the cookware, that is, obtains the second temperature of the cookware, it generates a speed recovery instruction for restoring the fan speed, and then sends the speed recovery instruction to the fan, so that the fan responds to the received speed recovery instruction and restores the fan speed.
[0191] By restoring the speed of the fan corresponding to the cookware, the oil smoke generated by the cookware can be discharged normally regardless of whether the cookware is in a dry-burning state.
[0192] S706: Based on the comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold, determine that the cookware is in a dry-boiling state, output a warning message that the cookware is in a dry-boiling state, and / or turn off the stove corresponding to the cookware.
[0193] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is in a dry-boil state when the second temperature is greater than or equal to the dry-boil temperature threshold.
[0194] When the dry-burn detection device determines that the cookware is in a dry-burn state, it generates a stove-off instruction for shutting down the cooker, and then sends the stove-off instruction to the cooker corresponding to the cookware. In response to the stove-off instruction, the cooker shuts down the burner, causing the burner to stop producing flames and thus stop heating the cookware.
[0195] When the dry-boiling detection device determines that the cookware is in a dry-boiling state, it generates a warning message for warning that the cookware is in a dry-boiling state, and outputs the warning message through the output device.
[0196] It is understood that different warning messages require different output devices. For example, when the warning message is a text or image prompt, the output device may be a display device on the dry-boil detection device; when the warning message is a buzzer, the output device may be a buzzer; when the warning message is an audible prompt, the output device may be an audio playback device, etc. The warning message may also be transmitted to an electronic device corresponding to the dry-boil detection device via an output interface, without limitation.
[0197] By turning off the stove corresponding to the cookware when the cookware is in a dry-burn state, the stove stops heating the cookware, thereby avoiding safety problems caused by continuous heating of the cookware in a dry-burn state, thereby improving the safety of the dry-burn detection device and the cookware; by outputting a warning message when the cookware is in a dry-burn state to warn the user / operator that the cookware is in a dry-burn state and there is a safety hazard, the user is allowed to deal with it as soon as possible, thereby improving the safety of the dry-burn detection device and the cookware.
[0198] S707: Determine that the cookware is not in a dry-boil state based on a comparison result that the second temperature is lower than the dry-boil temperature threshold.
[0199] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device compares the second temperature with a dry-boil temperature threshold to determine a magnitude relationship between the second temperature threshold and the dry-boil temperature threshold. The dry-boil detection device determines that the cookware is not dry-boiled when the second temperature is less than the dry-boil temperature threshold.
[0200] After determining that the cookware is not in a dry-boiling state, the dry-boiling detection device generates an on-instruction for starting the fan, and then sends the on-instruction to the fan. The fan turns on in response to the received on-instruction.
[0201] By restarting the fan when the pot is not in a dry state, you can ensure that the pot can cook properly.
[0202] In the embodiments of the present application, when the cookware is in a dry-burn state, the stove corresponding to the cookware is turned off, so that the stove stops heating the cookware, thereby avoiding safety problems caused by continuous heating of the cookware in a dry-burn state, and improving the safety of the dry-burn detection device and the cookware; when the cookware is in a dry-burn state, a warning message is output to warn the user / operator that the cookware is in a dry-burn state and there is a safety hazard, so that the user can deal with it as soon as possible, thereby improving the safety of the dry-burn detection device and the cookware; and when the cookware is not in a dry-burn state, the fan is restarted to ensure that the cookware can cook normally.
[0203] See Figure 11 , provides a flow chart of a dry burning detection method according to an embodiment of the present application. Figure 11 As shown, the method may include the following steps S801 to S806.
[0204] S801: Obtain a first temperature of the cookware.
[0205] Please refer to step S601 for details, which will not be repeated here.
[0206] S802: Based on a comparison result that the first temperature is greater than or equal to a dry-boiling temperature threshold, obtain a target rotation speed of a fan corresponding to the cookware.
[0207] In one implementation, the dry-boil temperature threshold is used to determine whether the cookware is in a dry-boil state. Specifically, when the temperature of the cookware is in a dry-boil state, it means that the cookware continues to heat up due to continuous dry-boil until it reaches the dry-boil temperature threshold. At this time, the temperature of the cookware is too high and there is a safety risk.
[0208] It should be noted that the dry-burn temperature threshold is not a fixed value. When the dry-burn detection device starts the dry-burn detection, it will first obtain the threshold parameters of the dry-burn detection device, such as the firepower value, cooking state, cooking mode, etc., and then determine the dry-burn temperature threshold based on at least one of the aforementioned threshold parameters. Specifically, the cooking state includes the water-based cooking state and the water-free cooking state, and the cooking modes include stir-frying, hot pot, porridge cooking, boiling water, making soup, etc. It can be understood that different cooking states correspond to different dry-burn temperature thresholds, different cooking modes also correspond to different dry-burn temperature thresholds, and different firepower value ranges also correspond to different dry-burn temperature thresholds. If several burn detection devices determine the dry-burn temperature threshold based on multiple threshold parameters, the dry-burn temperature threshold can be calculated according to the weights of different threshold parameters. It should be emphasized that the method of obtaining the dry-burn temperature threshold is not specifically limited in the embodiments of this application. After starting, the dry-burn detection device will first obtain the dry-burn temperature threshold corresponding to the current dry-burn detection process.
[0209] After obtaining the first temperature of the cookware, the dry-boil detection device compares the first temperature with the dry-boil temperature threshold to determine the magnitude relationship between the first temperature threshold and the dry-boil temperature threshold. When the first temperature is greater than or equal to the dry-boil temperature threshold, the dry-boil detection device determines the fan corresponding to the cookware whose first temperature is greater than or equal to the dry-boil temperature threshold, then obtains the current fan speed and uses this speed as the target fan speed.
[0210] S803: Reduce the rotation speed of the fan corresponding to the cookware.
[0211] In one implementation, the dry burn detection device generates a control instruction for reducing the speed of the fan, i.e., a speed reduction instruction, and then sends the control instruction (speed reduction instruction) to the fan, so that the fan reduces the speed of the fan in response to the received control instruction (speed reduction instruction), thereby reducing the wind force generated by the fan.
[0212] S804: After the set time, obtain the second temperature of the cookware.
[0213] Please refer to step S603 for details, which will not be repeated here.
[0214] S805: Restoring the wind speed of the fan corresponding to the cookware to the target speed.
[0215] In one implementation, after obtaining the second temperature of the cookware, the dry-boil detection device generates a speed recovery instruction based on the fan's target speed, which is used to restore the fan speed to the target speed. This speed recovery instruction carries the target speed, and then transmits the speed recovery instruction to the cooktop. In response to the received speed recovery instruction, the fan speed is restored to the target speed. It is understood that if the fan is off, it is necessary to first turn it on and then increase the fan speed to the target speed.
[0216] S806: Determine that the cookware is in a dry-boil state based on a comparison result that the second temperature is greater than or equal to the dry-boil temperature threshold.
[0217] Please refer to step S604 for details, which will not be repeated here.
[0218] In an embodiment of the present application, by restoring the fan's firepower to the fan's target firepower, the impact of the dry burning detection process on oil fume emissions is reduced, so that the oil generated by the pot can be normally discharged through the fan regardless of whether the pot is in a dry burning state.

[0225] In the embodiment of the present application, by reducing the fire power of the stove and lowering the height of the flame generated by the burner in the stove, the flame generated by the burner will not move to the surroundings after contacting the bottom of the pot due to being too high, thereby avoiding the flame burning directly at the temperature sensor and reducing the impact of the flame on the temperature sensor. At the same time, by re-acquiring the second temperature of the pot after a set time, the impact of the flame on the temperature sensor is also reduced. By improving the accuracy of the temperature sensor, the accuracy of the dry burning detection result is improved.

[0241] The state determination module 203 is configured to determine that the cookware is in a dry-boiling state based on a comparison result that the second temperature is greater than or equal to the dry-boiling temperature threshold.
[0242] In an embodiment of the present application, the rotation speed of the fan around the stove is reduced, thereby reducing the wind force generated by the fan, and further reducing the impact of the fan on the flame generated by the stove, so that the flame is reduced in deviation or stops deviating, so as to avoid the flame burning directly at the temperature sensor, thereby reducing the impact of the flame on the temperature sensor. At the same time, by re-obtaining the second temperature of the pot after a set time, the impact of the flame on the temperature sensor is also reduced. By improving the accuracy of the temperature sensor, the accuracy of the dry burning detection result is improved.
