[0088] Embodiment one

[0089] Please refer to Figure 1 , Figure 1 is a flowchart of a liquid temperature control method disclosed by an embodiment of the application. In the method, Figure 1 The liquid temperature control method described can be applied to a liquid temperature control device, which can include one of a temperature control equipment, a temperature control terminal, a temperature control system, and a server, wherein the server includes a local server or a cloud server, and the temperature control equipment can include one of an electric kettle, a cooking appliance, and a water heater, which are not limited by the embodiments of the application. As shown in Figure 1 The method can include the following operations:

[0090] 101. In the process of boiling the target liquid, the current actual temperature of the target liquid and the current sensing temperature of the target liquid are determined.

[0091] In the embodiments of the application, the current actual temperature of the target liquid and the current sensing temperature of the target liquid are temperature data determined at the same time. The target liquid can include one of water, soup, milk, coffee, and other liquids that need to be temperature controlled, which are not limited by the embodiments of the application; the current actual temperature of the target liquid can be temperature data measured by a probe of a calibrated temperature recorder, and further, the probe of the temperature recorder can be set at a preset height from the bottom of a container containing the target liquid for measurement, and further, the preset height can be a height determined according to the volume of the target liquid, for example, the preset height is 10 mm, which is not limited by the embodiments of the application; the current sensing temperature of the target liquid can be temperature data collected by a temperature sensor, or data obtained by processing the temperature data collected by the temperature sensor, which are not limited by the embodiments of the application.

[0092] Optionally, the current actual temperature of the target liquid and the current sensing temperature of the target liquid can be collected based on a temperature collection rule, where the temperature collection rule can include a collection frequency and / or a collection time, and the embodiments of the present application are not limited thereto.

[0093] 102. The current temperature difference of the target liquid is determined according to the current actual temperature of the target liquid and the current sensing temperature of the target liquid.

[0094] In the embodiments of the present application, the difference between the calculated current actual temperature of the target liquid and the current sensing temperature of the target liquid can be taken as the current temperature difference of the target liquid.

[0095] 103. The temperature threshold corresponding to the current actual temperature is determined according to the current temperature difference of the target liquid and the target temperature of the target liquid.

[0096] In the embodiments of the present application, the target temperature can be a pre-set temperature value, or a temperature value determined according to user demand, and the embodiments of the present application are not limited thereto; the temperature threshold corresponding to the current actual temperature includes a first temperature threshold corresponding to the current actual temperature and a second temperature threshold corresponding to the current actual temperature, and the first temperature threshold corresponding to the current actual temperature is smaller than the second temperature threshold corresponding to the current actual temperature. Wherein, the difference between the target temperature of the target liquid and the current temperature difference of the target liquid can be taken as the temperature threshold corresponding to the current actual temperature; or the target temperature of the target liquid and the current temperature difference of the target liquid can be substituted into a pre-set threshold calculation formula to calculate the temperature threshold corresponding to the current actual temperature. For example, assuming that the current temperature difference of the target liquid is T, the target temperature of the target liquid is T m , the first temperature threshold corresponding to the current actual temperature can be T m -(T+5), and the second temperature threshold corresponding to the current actual temperature can be T m -T.

[0097] 104. The control parameter corresponding to the current temperature control operation of the target liquid is determined according to the current actual temperature of the target liquid and the temperature threshold corresponding to the current actual temperature.

[0098] In the embodiment of the present application, the current temperature control operation of the target liquid is a heating operation or a stop heating operation. The heating operation is an operation of heating the target liquid, and the stop heating operation is an operation of stopping heating the target liquid. Because the actual water temperature of the target liquid is usually much higher than the sensing temperature of the target liquid, the sensing temperature collected by the temperature sensor will still rise in the state of stopping heating, so the stop heating operation can synchronize the sensing temperature of the target liquid to the actual temperature of the target liquid, so as to reduce the error of the temperature data collected by the temperature sensor. In addition, the control parameter corresponding to the current temperature control operation includes the heating power and / or the stop heating time length.

[0099] 105. Perform the current temperature control operation on the target liquid according to the control parameter corresponding to the current temperature control operation of the target liquid.

[0100] It can be seen that the method described in the embodiment of the present application can determine the current temperature difference value according to the determined current actual temperature and the current sensing temperature of the target liquid, determine the temperature threshold value corresponding to the current actual temperature according to the current temperature difference value and the target temperature, and determine the control parameter corresponding to the current temperature control operation according to the current actual temperature and the temperature threshold value corresponding to the current actual temperature. The control parameter is used to perform the current temperature control operation on the target liquid, which realizes the function of intelligently adjusting the control parameter corresponding to the current temperature control operation according to the temperature difference value, improves the accuracy of determining the temperature difference value, reduces the temperature deviation in the process of heating the liquid, and is beneficial to improving the control accuracy and control efficiency of the liquid temperature, thereby being beneficial to meeting the liquid temperature control demand of the user and improving the liquid temperature control experience of the user.

[0101] In an optional embodiment, determining the control parameter corresponding to the current temperature control operation of the target liquid according to the current actual temperature of the target liquid and the temperature threshold value corresponding to the current actual temperature can include the following operations:

[0102] When the current actual temperature of the target liquid is less than the first temperature threshold value corresponding to the current actual temperature, the control parameter corresponding to the current temperature control operation is determined as the first control parameter.

[0103] When the current actual temperature of the target liquid is greater than or equal to the first temperature threshold value corresponding to the current actual temperature, and the current actual temperature of the target liquid is less than the second temperature threshold value corresponding to the current actual temperature, the control parameter corresponding to the current temperature control operation is determined as the second control parameter.

[0104] When the current actual temperature of the target liquid is greater than or equal to the second temperature threshold value corresponding to the current actual temperature, and the current actual temperature of the target liquid is less than the target temperature, the control parameter corresponding to the current temperature control operation is determined as the third control parameter.

[0105] The first control parameter, the second control parameter and the third control parameter can be preset control parameters, or can be control parameters determined according to the specific value of the current actual temperature of the target liquid, and the embodiments of the present application are not limited.

[0106] It can be seen that the optional embodiment can perform situation classification based on the first temperature threshold value corresponding to the determined current actual temperature, the second temperature threshold value and the current actual temperature, and determine the control parameter corresponding to the current temperature control operation when the current actual temperature is in different temperature ranges, so as to improve the determination accuracy of the control parameter corresponding to the current temperature control operation, thereby improving the execution accuracy of the current temperature control operation, and further improving the control accuracy and control efficiency of the liquid temperature.

[0107] In the optional embodiment, optionally, when the current temperature control operation of the target liquid is a heating operation, the first control parameter includes a first power, the second control parameter includes a second power, and the third control parameter includes a third power, the first power is greater than the second power, and the second power is greater than the third power.

[0108] When the current temperature control operation of the target liquid is a stop heating operation, the first control parameter includes a first stop time, the second control parameter includes a second stop time, and the third control parameter includes a third stop time, the first stop time is less than the second stop time, and the second stop time is less than the third stop time.

[0109] For example, the first power can be full power, the second power can be half power, and the third power can be low power; the first stop time can be the minimum stop time, the second stop time can be the standard stop time, and the third stop time can be the extended stop time.

[0110] Further, assuming that the current actual temperature of the target liquid is T a , the current temperature difference of the target liquid is T, the target temperature of the target liquid is T m , the first temperature threshold value corresponding to the current actual temperature is T m -(T+5), and the second temperature threshold value corresponding to the current actual temperature is T m -T; and assuming that the rated power of the device for temperature control of the target liquid is 800W, the full power is 800W, the half power is 400W, and the low power is 100W-200W; and assuming that the minimum stop time is 0s and the extended stop time is 3s.

[0111] If the current temperature control operation is a heating operation, when T a <T m -(T+5), the control parameter corresponding to the current temperature control operation is 800W; when T m-(T+5)≤T a <T m -T, the control parameter corresponding to the current temperature control operation is 400W; when T m -T≤T a <T m 100-200W; if the current temperature control operation is a stop heating operation, when T a <T m -(T+5), the control parameter corresponding to the current temperature control operation is 0s; when T m -(T+5)≤T a <T m -T, the control parameter corresponding to the current temperature control operation is a standard stop duration; when T m -T≤T a <T m , the control parameter corresponding to the current temperature control operation is at least 3s.

[0112] It can be seen that the optional embodiment can also determine the type of control parameter according to the type of current temperature control operation, and specifically describes the numerical size relationship between each control parameter, which can improve the determination accuracy and efficiency of heating power and stop heating duration, thereby further improving the execution accuracy of the current temperature control operation.

[0113] In the optional embodiment, further optionally, the second stop duration can be determined in the following manner:

[0114] When the current temperature control operation of the target liquid is a heating operation, record the candidate temperature difference between the candidate actual temperature of the target liquid and the candidate sensing temperature of the target liquid, and the candidate sensing temperature of the target liquid is the sensing temperature of the target liquid collected at the same time as the candidate actual temperature;

[0115] When it is judged that the candidate temperature difference is greater than or equal to the preset difference threshold, stop performing the heating operation on the target liquid;

[0116] After stopping performing the heating operation on the target liquid, monitor the required duration for the candidate sensing temperature of the target liquid to rise to the preset sensing temperature, and determine the required duration as the second stop duration.

[0117] The second stop duration can be a standard stop duration, which can be used as a reference parameter for determining other stop durations. The control parameter corresponding to the heating operation can be the first power, the second power, the third power, or other heating power values, which are not limited by the embodiments of the present application. The preset sensing temperature can be a preset temperature value or a temperature value determined according to the candidate sensing temperature, for example, a temperature value after the candidate sensing temperature is increased by 1°C.

[0118] Optionally, when multiple candidate temperature difference values are recorded, a candidate temperature difference value greater than or equal to a preset difference threshold value can be selected from all candidate temperature difference values, and the heating operation on the target liquid is immediately stopped.

[0119] For example, assuming that the control parameter corresponding to the heating operation is full power, when the difference between the actual temperature of the target liquid and the sensing temperature of the target liquid reaches the maximum difference, the heating of the target liquid is immediately stopped, the time required for the target liquid to rise by 1°C at this time is detected, and the required time is recorded as t, and t is used as the standard stop time.

[0120] It can be seen that the optional embodiment can also determine the candidate temperature difference value according to the candidate actual temperature and the candidate sensing temperature of the target liquid, stop the heating operation on the target liquid when the candidate temperature difference value is greater than or equal to the preset difference threshold value, and immediately start detecting the time required for the candidate sensing temperature to rise to the preset sensing temperature, and use the required time as the second stop duration, which can improve the accuracy of determining the second stop duration, thereby improving the efficiency of determining the control parameter corresponding to the current temperature control operation.

[0121] In another optional embodiment, before determining the control parameter corresponding to the current temperature control operation according to the current actual temperature and the temperature threshold value corresponding to the current actual temperature, the method can further include the following operations:

[0122] Determining a temperature influencing factor of the target liquid.

Wherein, Figure 2The liquid temperature control method described can be applied to a liquid temperature control device, which can include one of a temperature control apparatus, a temperature control terminal, a temperature control system, and a server, wherein the server includes a local server or a cloud server, and the temperature control apparatus can include one of an electric kettle, a cooking appliance, and a water heater, and the present embodiment is not limited. As shown in Figure 2 The liquid temperature control method can include the following operations:

[0137] 204. It is judged whether the current sensing temperature of the target liquid reaches the target temperature. When the judgment result of step 204 is yes, the process is ended; when the judgment result of step 204 is no, step 205 is triggered to be executed.

[0138] 205. The current temperature control operation of the target liquid is determined.

[0139] In the present embodiment, the current temperature control operation of the target liquid can include the following operations:

[0140] It is judged whether the sensing temperature change corresponding to the current sensing temperature of the target liquid is used to indicate that the sensing temperature of the target liquid has an upward trend;

[0141] When it is judged that the sensing temperature change corresponding to the current sensing temperature of the target liquid is used to indicate that the sensing temperature of the target liquid has an upward trend, the current temperature control operation of the target liquid is determined as a stop heating operation;

[0142] When it is judged that the sensing temperature change corresponding to the current sensing temperature of the target liquid is used to indicate that the sensing temperature of the target liquid does not have an upward trend, the current temperature control operation of the target liquid is determined as a heating operation.

[0143] Wherein, the sensing temperature of the target liquid has an upward trend can be used to indicate that the difference between the current sensing temperature of the target liquid and the previous sensing temperature of the target liquid is greater than a preset heating temperature threshold, and the previous sensing temperature is the sensing temperature of the target liquid collected last time; the preset heating temperature threshold can be a temperature value determined in advance, or a temperature value determined according to the current sensing temperature of the target liquid, and the present embodiment is not limited.

[0144] It can be seen that the method described in the embodiment of the present application can determine the type of the current temperature control operation when the sensing temperature of the target liquid has an upward trend, and the current temperature control operation is the stop heating operation, and when the sensing temperature of the target liquid has no upward trend, the current temperature control operation is the heating operation, thereby improving the accuracy of determining the type of the current temperature control operation, and improving the efficiency of the control parameter corresponding to the current temperature control operation.

[0145] It should be noted that the steps 204-205 have no sequence relationship with any one of the steps 202-203, that is, the steps 204-205 can occur before or after any one of the steps 202-203 or simultaneously with any one of the steps 202-203, and the embodiment of the present application does not limit the sequence.

In addition, it can also be determined whether the current sensing temperature reaches the target temperature before determining the control parameter corresponding to the current temperature control operation. If the current sensing temperature reaches the target temperature, subsequent operations do not need to be performed, otherwise the current temperature control operation is determined according to the sensing temperature change of the target liquid, which can improve the accuracy of performing the operation of determining the control parameter corresponding to the current temperature control operation, thereby reducing the energy consumption of liquid temperature control and improving the control efficiency of liquid temperature.

[0150] In an optional embodiment, determining the current sensing temperature of the target liquid can include the following operations:

[0151] Collecting the temperature of the target liquid based on the temperature sensors in the target liquid corresponding to different positions in the containing container to obtain a sensing temperature set of the target liquid, the temperature sensor set including at least one temperature sensor, and the sensing temperature set of the target liquid including at least one sensing temperature collected by the temperature sensor;

[0153] Determining the current sensing temperature of the target liquid according to the sensing temperature set of the target liquid and the calibration coefficient corresponding to the sensing temperature collected by each temperature sensor.

[0154] The calibration coefficient corresponding to the sensing temperature collected by each temperature sensor is used to calibrate the sensing temperature collected by each temperature sensor. Further, if the temperature sensor set includes multiple temperature sensors, the calibration coefficient can also be used to integrate the sensing temperatures collected by the multiple temperature sensors to determine the current sensing temperature of the target liquid.

[0155] It can be seen that the optional embodiment can determine the calibration coefficient corresponding to the sensing temperature collected by each temperature sensor, and calibrate and integrate the sensing temperature collected by each temperature sensor according to the calibration coefficient, so as to determine the current sensing temperature of the target liquid, reduce the error degree of the sensing temperature, improve the accuracy of determining the current sensing temperature of the target liquid, and further improve the accuracy of determining the control parameter corresponding to the current temperature control operation.

[0160] According to the positional relationship between each temperature sensor and the liquid level of the target liquid, determining the calibration coefficient corresponding to the sensing temperature collected by each temperature sensor.

[0161] The positional relationship between each temperature sensor and the liquid level of the target liquid can include the distance between each temperature sensor and the liquid level of the target liquid and / or the azimuthal relationship between each temperature sensor and the liquid level of the target liquid. Further, if the center point of the liquid level of the target liquid is taken as the center, the azimuthal relationship between each temperature sensor and the liquid level of the target liquid can include the directional relationship between each temperature sensor and the center point of the liquid level and / or the distance relationship between each temperature sensor and the center point of the liquid level, which is not limited by the embodiments of the present application.

[0162] It can be seen that the optional embodiment can also determine the positional relationship between each temperature sensor and the liquid level of the target liquid according to the position of each temperature sensor and the liquid level position of the target liquid, and determine the calibration coefficient corresponding to the sensing temperature collected by each temperature sensor according to the above positional relationship, so as to improve the accuracy of determining the calibration coefficient, further reduce the error degree of the sensing temperature, and further improve the accuracy of determining the current sensing temperature of the target liquid.

[0163] In the optional embodiment, further optionally, according to the positional relationship between each temperature sensor and the liquid level of the target liquid, determining the calibration coefficient corresponding to the sensing temperature collected by each temperature sensor can include the following operations:

[0164] According to the positional relationship between each temperature sensor and the liquid level of the target liquid, the collection rate of each temperature sensor and the error estimation value of the sensed temperature collected by each temperature sensor are determined.

[0165] According to the collection rate of each temperature sensor and the error estimation value of the sensed temperature collected by each temperature sensor, the calibration coefficient corresponding to the sensed temperature collected by each temperature sensor is determined.

[0166] It can be seen that the optional embodiment can also determine the collection rate of each temperature sensor and the error estimation value of the sensed temperature collected by each temperature sensor according to the positional relationship between each temperature sensor and the liquid level of the target liquid, and determine the calibration coefficient corresponding to the sensed temperature collected by each temperature sensor in combination with the collection rate and the error estimation value, which can improve the accuracy of the reference basis for determining the calibration coefficient, thereby improving the accuracy of determining the calibration coefficient.

[0167] In addition, in the embodiment of the present application, when the liquid temperature control method is applied to an electric kettle, the flowchart corresponding to the method can be as shown in Figure 3 , and the technical solution described by the method can be:

[0168] Assuming that the target liquid is water, when the electric kettle starts to work, the heating power Px (unit: watt) is determined according to the difference between the first current temperature and the target temperature, and the current temperature includes the current actual temperature and the current sensed temperature; the electric kettle is controlled to heat the water according to the heating power Px, and during the heating process, it is detected whether the current temperature of the water rises; if it is detected that the current temperature of the water does not rise, the heating continues.

[0169] If it is detected that the current temperature of the water has risen, the stop heating duration Tx (unit: second) is determined according to the difference between the second current temperature and the target temperature; after the stop heating duration Tx, it is judged whether the third current temperature reaches the target temperature; when it is judged that the third current temperature reaches the target temperature, the electric kettle is controlled to end the heating process; when it is judged that the third current temperature does not reach the target temperature, the operation of determining the heating power according to the difference between the current temperature and the target temperature and the subsequent operation is re-executed until the current temperature reaches the target temperature.

[0170] For example, when the liquid temperature control method is applied to an electric kettle, and the flowchart corresponding to the method is as shown in Figure 3 , the temperature deviation and the completion time comparison diagram before and after the method is improved as shown in Figure 4 , the liquid temperature control method described in the embodiment of the present application is the improved method. Among them, Figure 4The final water temperature deviation from the target temperature when the water boiling process is completed and the completion time of the water boiling process before and after the method is improved are compared under six combinations of voltage of 198V, 220V, 242V, and low water volume (for example, 150ml) and high water volume (for example, 1.5L). Under the condition of low water volume, if the liquid temperature control method before the improvement is used, the final water temperature deviation from the target temperature when the water boiling process is completed is larger and much higher than that when the improved method is used, but the completion time of the water boiling process is slightly lower than that when the improved method is used. Under the condition of high water volume, the temperature deviation generated by using the liquid temperature control method before the improvement is still higher than that by using the liquid temperature control method after the improvement, and the completion time of the method before the improvement is much higher than that of the method after the improvement. It can be seen that the method described in the embodiment of the application can reduce the temperature deviation of the final temperature from the target temperature, improve the accuracy of temperature control, and at the same time, under the condition of low water volume, the completion time can be maintained at the level of the completion time before the improvement, and under the condition of high water volume, the completion time is shortened, and the temperature control efficiency is improved.

[0171] Specifically, taking the target temperature of 55℃ as an example, the final water temperature and the completion time corresponding to each of the above six combinations are shown in Table 1.

If the current sensing temperature reaches the target temperature, the subsequent operation does not need to be performed. Otherwise, the current temperature control operation is determined according to the sensing temperature change of the target liquid, which can improve the accuracy of the operation of determining the control parameter corresponding to the current temperature control operation, thereby reducing the energy consumption of the liquid temperature control and improving the control efficiency of the liquid temperature. In addition, when the sensing temperature of the target liquid has an upward trend, the current temperature control operation is the stop heating operation. When the sensing temperature of the target liquid does not have an upward trend, the current temperature control operation is the heating operation, which can improve the accuracy of determining the type of the current temperature control operation, thereby improving the efficiency of the control parameter corresponding to the current temperature control operation.

[0194] When the current actual temperature of the target liquid is greater than or equal to the second temperature threshold corresponding to the current actual temperature and less than the target temperature, the control parameter corresponding to the current temperature control operation is determined as the third control parameter.
