Description

Technical Field

[0001] The present application relates to the technical field of cooking appliance control, and in particular to a cooking appliance temperature deviation monitoring method and system. Background Art

[0002] During the cooking process, a large number of small oil droplets may be produced on the sensor surface. If the small oil droplets on the sensor surface are not cleaned in time, an oil film may be formed on the sensor surface, thereby affecting the measurement results of the sensor. After long-term use of the cooking appliance, power deviation may occur in the upper and lower conduits, resulting in failure to achieve the ideal cooking effect when cooking food. Therefore, the present application proposes a cooking appliance temperature deviation monitoring method and system.

[0003] Prior art, such as the invention patent application with announcement number: CN110146195B, discloses a method, device, cooking utensil, and readable storage medium for determining temperature deviation. It includes: receiving a first temperature value and a second temperature value, and receiving a temperature monitoring value sent from a sensor; recording the heating time when the temperature monitoring value rises from the first temperature value to the second temperature value; determining the time difference between the heating time and the reference time; and determining the current temperature deviation of the sensor according to the time difference. By comparing the heating time when the temperature monitoring value rises from the first temperature value to the second temperature value with the reference time, the time difference between the heating time and the reference time is determined, and the current temperature deviation of the temperature monitoring value is determined using the determined time difference, so as to calibrate the sensor, thereby getting rid of the dilemma in the related technical solutions that the user has difficulty in manual cleaning, cannot ensure that the oil layer is completely cleaned, and cannot determine the measurement deviation.

[0004] With respect to the above scheme, there are the following technical problems: 1. The current technology mainly determines the first temperature value, the second temperature value and the temperature monitoring value of the sensor, and then determines the heating time of the first temperature value and the second temperature value, and then uses the difference between the heating time and the reference time to determine the temperature deviation of the current sensor. The current technology does not take into account that the temperature deviation may be caused by sensor failure. Long-term and large amounts of high-temperature oil droplets adhere to the sensor surface may affect the sensor performance. The current neglect of this aspect may result in the cooking utensils still failing to achieve the ideal cooking effect after temperature calibration.

[0005] 2. Current technology does not take into account that when cooking food, oil droplets will not only adhere to the sensor surface, but also to the surface of each heating tube, causing the heating tube to heat the food unevenly. Therefore, it is also very important to calibrate the power of each heating tube of the cooking appliance based on the temperature deviation. The current neglect of this aspect will result in the temperature deviation calibration of the cooking appliance failing to achieve the ideal effect, thus causing a waste of resources. Summary of the invention

[0006] The purpose of the present application is to provide a cooking appliance temperature deviation monitoring method and system, which solves the problems existing in the background technology.

[0007] To solve the above technical problems, the present application adopts the following technical solution: In a first aspect, the present application provides a method for monitoring temperature deviation of cooking appliances, comprising: Step 1, temperature data monitoring: monitoring first temperature data through a first monitoring unit in the target cooking appliance, and monitoring second temperature data through a second monitoring unit.

[0008] Step 2, temperature data analysis: Analyze whether the second monitoring unit fails based on the first temperature data, analyze the temperature deviation and temperature deviation change of the target cooking appliance based on the second temperature data, and analyze the power of each heating tube of the target cooking appliance.

[0009] Step 3: Temperature calibration: temperature calibrate the target cooking utensil according to its temperature deviation and the change of temperature deviation, and control the power of each heating tube according to the power analysis result of each heating tube of the target cooking utensil.

[0010] Step 4, execution terminal: monitor the temperature data of the target cooking appliance in the current preset cycle, and then analyze whether the above temperature calibration is accurate.

[0011] Preferably, the first temperature data includes the inner cavity temperature of the target cooking utensil after each cooking is completed within a historical preset period and the foreign matter temperature on the surface of the second monitoring unit; the second temperature data includes the preset cooking temperature, the actual cooking temperature, and the bottom temperature, top temperature and side temperature of each utensils for holding cooked food after cooking is completed of each cooking food in the target cooking utensil within the historical preset period.

[0012] Preferably, the analysis of whether the second monitoring unit is faulty based on the first temperature data is specifically performed as follows: based on the first temperature data, the target cooking utensil inner cavity temperature after each cooking is completed and the foreign matter temperature on the surface of the second monitoring unit are extracted, and the preset temperature of the cooking food corresponding to each cooking is extracted from the second temperature data, and the target cooking utensil inner cavity temperature after each cooking is completed is compared with the corresponding preset temperature of each cooking food. When the target cooking utensil inner cavity temperature after a certain cooking is inconsistent with the corresponding preset temperature of the food cooked at that time, it indicates that the monitoring data of the second monitoring unit deviates, and the cooking is recorded as temperature-deviation cooking. Otherwise, it indicates that the monitoring data of the second monitoring unit does not deviate, and the cooking is recorded as temperature-non-deviation cooking. Based on this, the number of temperature-non-deviation cooking times and the number of temperature-deviation cooking times in the historical preset period are obtained. When the number of temperature-deviation cooking times is greater than or equal to the set temperature-deviation cooking times threshold, it indicates that the second monitoring unit is not faulty but the monitored temperature data deviates, and calibration is required.

[0013] The inner cavity temperature of the target cooking utensil after each cooking is completed is compared with the surface foreign matter temperature of the second monitoring unit. When the inner cavity temperature of the target cooking utensil is inconsistent with the surface foreign matter temperature of the second monitoring unit after a certain cooking is completed, it indicates that the second monitoring unit has a fault in this monitoring, and the monitoring process of the second monitoring unit is recorded as fault monitoring; otherwise, it indicates that the second monitoring unit has not a fault in this monitoring, and the monitoring process of the second unit is recorded as non-fault monitoring. Based on this, the number of fault monitorings and the number of non-fault monitorings in a preset historical period are obtained. When the number of fault monitorings in the preset historical period is greater than or equal to the set fault monitoring number threshold, it indicates that the second monitoring unit of the target cooking utensil has a fault, otherwise it indicates that the second monitoring unit of the target cooking utensil has not a fault.

[0014] Preferably, the power of the heating tubes in each region of the target cooking utensil is analyzed, and the specific analysis process is as follows: based on the second temperature data, the bottom temperature, top temperature and side temperature of the utensil for holding cooking food after each cooking is completed are obtained, and the bottom temperature of the utensil for holding cooking food after each cooking is completed is compared with the corresponding inner cavity temperature of the target cooking utensil; when the bottom temperature of the utensil for holding cooking food after a certain cooking is completed is consistent with the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking utensil meets the cooking requirements; when the bottom temperature of the utensil for holding cooking food is greater than the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking container is too large; when the bottom temperature of the utensil for holding cooking food is less than the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking utensil is too small; similarly, the power of the top heating tube and the side heating tube of the target cooking utensil can be analyzed and obtained.

[0015] Preferably, the power of each heating conduit is controlled according to the power analysis result of each heating tube of the target cooking utensil, and the specific process is as follows: when the power of the conduit at the bottom of the target cooking utensil meets the cooking requirements, there is no need to perform power control on it.

[0016] When the power of the conduit at the bottom of the target cooking utensil is too high, the control center reduces the power of the heating tube at the bottom of the target cooking utensil until the bottom temperature of the container holding the cooked food after the preset cooking time is the same as the inner cavity temperature of the target cooking utensil.

[0017] When the duct power at the bottom of the target cooking container is lower than the preset bottom duct power, the bottom heating tube power of the target cooking utensil is increased through the control center; similarly, the power of the top heating tube and the side heating tube of the target cooking container is controlled through the control center.

[0018] Preferably, the temperature data of the target cooking appliance of the current preset cycle includes first temperature data monitored by a first monitoring unit and second temperature data monitored by a second monitoring unit.

[0019] Preferably, the specific process of analyzing whether the above-mentioned temperature calibration is accurate is as follows: analyzing whether the second monitoring unit is faulty based on the first temperature data; if the second monitoring unit is faulty, it is impossible to determine whether the above-mentioned temperature calibration is accurate.

[0020] Based on the second temperature data, the target cooking utensil inner cavity temperature after each cooking is completed and the preset cooking temperature of the corresponding food to be cooked are obtained, and the target cooking utensil inner cavity temperature after each cooking is completed and the preset cooking temperature of the corresponding food to be cooked are compared. When the target cooking utensil inner cavity temperature after each cooking is completed is consistent, it indicates that the temperature deviation calibration of the sensor is accurate, otherwise it indicates that the temperature deviation calibration of the sensor is inaccurate.

[0021] The bottom temperature, top temperature and side temperature of the container containing the cooked food in the target cooking utensil after each cooking is completed are obtained based on the second temperature data, and the bottom temperature, top temperature and side temperature of the container containing the cooked food in the target cooking utensil are respectively compared with the corresponding inner cavity temperature of the target cooking utensil to obtain whether the power of each heating tube of the target cooking utensil meets the requirement. When the power of each heating tube of the target cooking utensil meets the requirement, it indicates that the cooking tube power of the target cooking utensil is accurately calibrated, otherwise it indicates that the cooking tube power of the target cooking utensil is inaccurately calibrated.

[0022] When the second monitoring unit does not fail, the temperature deviation of the target cooking appliance is accurately calibrated, and the power of the heating tube of the target cooking appliance is accurately calibrated, it indicates that the calibration is accurate; otherwise, it indicates that the calibration is inaccurate.

[0023] In a second aspect, the present application provides a cooking appliance temperature deviation monitoring system, comprising: a temperature data monitoring module: monitoring first temperature data through a first monitoring unit in a target cooking appliance, and monitoring second temperature data through a second monitoring unit.

When the fault type is a performance fault, the second monitoring unit is repaired or replaced. When the fault type is foreign matter attached to the surface, the second monitoring unit is temperature calibrated. The temperature calibration includes analyzing the temperature deviation, temperature deviation change and power of each heating tube of the target cooking utensil, and adjusting the temperature and heating tube power of the target cooking utensil accordingly, thereby avoiding the problem of partially burnt and partially undercooked food due to uneven heating, and ensuring the taste and flavor of the cooked food.

[0028] 2. The present application obtains first temperature data through the first monitoring unit in the target cooking utensil, and obtains second temperature data through the second monitoring unit, which provides a strong data basis for the subsequent analysis of the temperature deviation of the target cooking utensil.

The temperature of the target cooking utensil is calibrated based on the temperature deviation of the target cooking utensil and the temperature deviation change curve.

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0033] Figure 1 The figure is a flowchart of the implementation steps of the present application method.

[0034] Figure 2 This is a schematic diagram of the system structure connection for this application. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Reference Figure 1 As shown, the present application provides a cooking appliance temperature deviation monitoring method in a first aspect, comprising the following steps: Step 1, temperature data monitoring: monitoring first temperature data through a first monitoring unit in a target cooking appliance, and monitoring second temperature data through a second monitoring unit.

[0037] It should be noted that the target cooking appliances include ovens and microwave ovens.

[0038] It should be noted that the first monitoring unit includes a detachable temperature sensor, and the second monitoring unit includes a temperature sensor in the target cooking utensil. The first monitoring unit is disassembled and cleaned after each cooking of food is completed within a historical preset period to ensure the accuracy of the monitoring results.

[0039] In a specific example, the first temperature data includes the target cooking utensil inner cavity temperature and the second monitoring unit surface foreign matter temperature after each cooking is completed within a historical preset period; the second temperature data includes the preset cooking temperature, actual cooking temperature, and bottom temperature, top temperature, and side temperature of each utensils for holding cooked food after cooking is completed in the target cooking utensil within the historical preset period.

[0040] It should be noted that the length of the historical preset cycle is set by the relevant testers, such as one week, half a month or one month.

[0041] It should be noted that foreign matter on the surface of the second monitoring unit includes oil droplets, oil film, food residues and the like.

[0042] Step 2, temperature data analysis: Analyze whether the second monitoring unit fails based on the first temperature data, analyze the temperature deviation and temperature deviation change of the target cooking appliance based on the second temperature data, and analyze the power of each heating tube of the target cooking appliance.

[0043] It should be noted that the fault is represented by inaccurate monitoring data of the second monitoring unit.

[0044] In a specific example, the analysis of whether the second monitoring unit is faulty based on the first temperature data is as follows: based on the first temperature data, the target cooking utensil inner cavity temperature after each cooking is completed and the foreign matter temperature on the surface of the second monitoring unit are extracted, and the preset temperature of the cooking food corresponding to each cooking is extracted from the second temperature data, and the target cooking utensil inner cavity temperature after each cooking is completed is compared with the corresponding preset temperature of each cooking food. When the target cooking utensil inner cavity temperature after a certain cooking is inconsistent with the corresponding preset temperature of the food cooked at that time, it indicates that the monitoring data of the second monitoring unit is deviated, and the cooking is recorded as temperature-deviation cooking. Otherwise, it indicates that the monitoring data of the second monitoring unit is not deviated, and the cooking is recorded as temperature-non-deviation cooking. Based on this, the number of temperature-non-deviation cooking times and the number of temperature-deviation cooking times in the historical preset period are obtained. When the number of temperature-deviation cooking times is greater than or equal to the set temperature-deviation cooking times threshold, it indicates that the second monitoring unit is not faulty but the monitored temperature data is deviated and needs to be calibrated.

[0045] It should be noted that the temperature deviation cooking times threshold is set by the relevant testers. The smaller the temperature deviation cooking times threshold is, the higher the accuracy requirement for the temperature data monitored by the sensor. For example, the temperature deviation cooking times threshold can be set to 0, and no specific restrictions are made here.

[0046] The inner cavity temperature of the target cooking utensil after each cooking is completed is compared with the surface foreign matter temperature of the second monitoring unit. When the inner cavity temperature of the target cooking utensil is inconsistent with the surface foreign matter temperature of the second monitoring unit after a certain cooking is completed, it indicates that the second monitoring unit has a fault in this monitoring, and the monitoring process of the second monitoring unit is recorded as fault monitoring; otherwise, it indicates that the second monitoring unit has not a fault in this monitoring, and the monitoring process of the second unit is recorded as non-fault monitoring. Based on this, the number of fault monitorings and the number of non-fault monitorings within a preset historical period are obtained. When the number of fault monitorings within the preset historical period is greater than or equal to the set fault monitoring number threshold, it indicates that the second monitoring unit of the target cooking utensil has a fault. Otherwise, it indicates that the second monitoring unit of the target cooking utensil has not a fault.

[0047] It should be noted that the setting method of the fault monitoring times threshold is the same as the temperature deviation cooking times threshold, so it will not be repeated here.

[0048] It should be noted that, when the second monitoring unit of the target cooking appliance fails, the second monitoring unit of the target cooking appliance needs to be replaced to ensure the accuracy of temperature monitoring.

[0049] In a specific example, the temperature deviation and the change of the temperature deviation of the target cooking utensil are analyzed according to the second temperature data. The specific analysis process is as follows: based on the second temperature data, the preset cooking temperature and the actual cooking temperature of each cooking food in the target cooking utensil within the historical preset period are obtained, and the cooking time of each cooking food is obtained from the control center, and recorded as , and ,in Indicates the number of cooking times. , is any integer greater than 2, according to the calculation formula: The analysis obtained Temperature deviation of the target cooking appliance during cooking , based on which the temperature deviation of the target cooking utensil during each cooking is obtained.

[0050] The temperature deviation of the target cooking utensil during each cooking in the historical preset period is fitted into a target cooking utensil temperature deviation change curve, and the endpoint coordinates of the target cooking utensil temperature deviation change curve are obtained. And calculate the endpoint slope ,in is the horizontal coordinate of the temperature deviation change curve of the target cooking utensil, is the ordinate of the target cooking utensil temperature deviation change curve, the endpoint coordinates and endpoint slope of the comprehensive target cooking utensil temperature deviation change curve , the change of temperature deviation of the target cooking utensil can be obtained.

[0051] In a specific example, the power of the heating tubes in each region of the target cooking utensil is analyzed, and the specific analysis process is as follows: based on the second temperature data, the bottom temperature, top temperature and side temperature of the utensil for holding cooking food after each cooking is completed are obtained, and the bottom temperature of the utensil for holding cooking food after each cooking is completed is compared with the corresponding inner cavity temperature of the target cooking utensil. When the bottom temperature of the utensil for holding cooking food after a certain cooking is completed is consistent with the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking utensil meets the cooking requirements; when the bottom temperature of the utensil for holding cooking food is greater than the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking container is too large; when the bottom temperature of the utensil for holding cooking food is less than the corresponding inner cavity temperature of the target cooking utensil, it indicates that the power of the bottom heating tube of the target cooking utensil is too small; similarly, the power of the top heating tube and the side heating tube of the target cooking utensil can be analyzed and obtained.

[0052] It should be noted that if the power of the heating tube in the target cooking appliance is too high or too low, it will cause uneven heating of the food being cooked, thereby affecting the cooking effect.

[0053] Step 3: Temperature calibration: temperature calibrate the target cooking utensil according to its temperature deviation and the change of temperature deviation, and control the power of each heating tube according to the power analysis result of each heating tube of the target cooking utensil.

[0054] In a specific example, the temperature of the target cooking utensil is calibrated according to the temperature deviation of the target cooking utensil and the change of the temperature deviation. The specific process is as follows: the preset temperature and cooking time of the food being cooked in the current cycle are obtained from the control center of the target cooking utensil, and they are recorded as and , the endpoint slope of the temperature change curve of the comprehensive target cooking utensil , the preset temperature of the food currently being cooked and cooking time , according to the calculation formula: Analyze and obtain the sensor monitoring temperature of the food being cooked in the current cycle , based on which the temperature of the sensor of the target cooking appliance is calibrated.

[0055] In a specific example, the power of each heating tube is controlled according to the power analysis result of each heating tube of the target cooking utensil. The specific process is as follows: when the power of the tube at the bottom of the target cooking utensil meets the cooking requirements, there is no need to control its power.

[0056] When the power of the conduit at the bottom of the target cooking utensil is too high, the control center reduces the power of the heating tube at the bottom of the target cooking utensil until the bottom temperature of the container holding the cooked food after the preset cooking time is the same as the inner cavity temperature of the target cooking utensil.

[0057] When the duct power at the bottom of the target cooking container is lower than the preset bottom duct power, the bottom heating tube power of the target cooking utensil is increased through the control center; similarly, the power of the top heating tube and the side heating tube of the target cooking container is controlled through the control center.

[0058] It should be noted that the target control center realizes the power control of each heating tube by running the stored code.

[0059] Step 4, execution terminal: monitor the temperature data of the target cooking appliance in the current preset cycle, and then analyze whether the above temperature calibration is accurate.

[0060] In a specific example, the temperature data of the target cooking appliance in the current preset cycle includes first temperature data monitored by a first monitoring unit and second temperature data monitored by a second monitoring unit.

[0061] In a specific example, the analysis of whether the temperature calibration is accurate is specifically performed as follows: analyzing whether the second monitoring unit is faulty based on the first temperature data; if the second monitoring unit is faulty, it is impossible to determine whether the temperature calibration is accurate.

[0062] Based on the second temperature data, the target cooking utensil inner cavity temperature after each cooking is completed and the preset cooking temperature of the corresponding food to be cooked are obtained, and the target cooking utensil inner cavity temperature after each cooking is completed and the preset cooking temperature of the corresponding food to be cooked are compared. When the target cooking utensil inner cavity temperature after each cooking is completed is consistent, it indicates that the temperature deviation calibration of the sensor is accurate, otherwise it indicates that the temperature deviation calibration of the sensor is inaccurate.

[0063] The bottom temperature, top temperature and side temperature of the container containing the cooked food in the target cooking utensil after each cooking is completed are obtained based on the second temperature data, and the bottom temperature, top temperature and side temperature of the container containing the cooked food in the target cooking utensil are respectively compared with the corresponding inner cavity temperature of the target cooking utensil to obtain whether the power of each heating tube of the target cooking utensil meets the requirement. When the power of each heating tube of the target cooking utensil meets the requirement, it indicates that the cooking tube power of the target cooking utensil is accurately calibrated, otherwise it indicates that the cooking tube power of the target cooking utensil is inaccurately calibrated.

[0064] When the second monitoring unit does not fail, the temperature deviation of the target cooking appliance is accurately calibrated, and the power of the heating tube of the target cooking appliance is accurately calibrated, it indicates that the calibration is accurate; otherwise, it indicates that the calibration is inaccurate.

[0065] Reference Figure 2 As shown, the present application provides a cooking appliance temperature deviation monitoring system in a second aspect, including: a temperature data monitoring module: monitoring first temperature data through a first monitoring unit in a target cooking appliance, and monitoring second temperature data through a second monitoring unit.

When the fault type is a performance fault, the second monitoring unit is repaired or replaced. When the fault type is foreign matter attached to the surface, the second monitoring unit is temperature calibrated. The temperature calibration includes analyzing the temperature deviation, temperature deviation change and power of each heating tube of the target cooking utensil, and adjusting the temperature and heating tube power of the target cooking utensil accordingly, thereby avoiding the problem of partially burnt and partially undercooked food due to uneven heating, and ensuring the taste and flavor of the cooked food.
