Description

Boiling temperature display method of water boiling device

Technical Field

The application belongs to the technical field of water boiling devices, and particularly relates to a boiling temperature display method of a water boiling device.

Background

At present, a temperature sensing element of a water boiling device such as a tea bar machine and a water kettle is usually arranged at the bottom of the water boiling device and is used for detecting the water temperature in the water kettle. However, due to possible errors in the installation process and differences in the temperature sensing of the temperature sensing element body, there may be differences between the actual measured temperature of the water in the water boiling device and the temperature sensing temperature of the temperature sensing element, and in addition, when the temperature is displayed, the temperature is displayed by the temperature sensing temperature of the temperature sensing element, which is usually the case, and the display temperature is inaccurate. In general, elements such as a negative temperature coefficient thermistor (Negative Temperature Coefficient, NTC), a thermocouple, a thermistor, a resistance temperature detector (Resistance Temperature Detector, RTD), and a digital thermometer IC are often selected in the water heating apparatus to sense temperature.

Taking temperature sensing NTC as an example, in software design, a large quantity of water heating devices are generally extracted to measure NTC temperature sensing data, average temperature is obtained, and then the temperature sensing NTC value is adjusted to the actual temperature of water by means of temperature compensation and the like, so that the temperature is displayed. However, the air pressure and the air density of different altitude areas are different, which may affect the accuracy of the NTC temperature sensing element, and in the high altitude areas, the air is thin, the air pressure is low, which may affect the response of the NTC temperature sensing element to the temperature, and in addition, the consistency of the measurement results of the NTC temperature sensor products of the same type and the same manufacturer at the same temperature may be different in readings of different NTC elements even at the same temperature if the consistency of the NTC elements is not good, thereby causing measurement errors. In addition, if the kettle is heated in a state without water or the NTC element is aged by long-term use, this may cause a change in the temperature sensing performance of the NTC element, thereby affecting the accuracy thereof.

The traditional temperature display is based on the temperature sensing temperature of the temperature sensing element, and the display temperature cannot meet the display requirement of the boiling temperature due to the limitation of the temperature accuracy of the temperature sensing element.

The embodiment of the application provides a boiling temperature display method of a water boiling device, and it should be noted that an execution subject of the embodiment of the application may be a server, or may be any device with data processing capability. Fig. 1 is a schematic flow chart of a boiling temperature display method of a water boiling device according to an embodiment of the present application, as shown in fig. 1, mainly including the following steps:

step S101, under the triggering of a water heating control instruction of a user, continuous heating is carried out, and the real-time sensing temperature of the temperature sensing assembly is determined.

In one embodiment of the present application, the water heating device such as a water kettle may begin to continue heating after the user's water heating control command triggers. In the process, the temperature sensing assembly senses and detects the change of the water temperature in real time. The current real-time temperature can be obtained by measuring the resistance value or other relevant parameters of the temperature sensing assembly. The real-time temperature obtained at this time is the real-time sensing temperature of the temperature sensing assembly, and the temperature sensing assembly comprises elements such as a negative temperature coefficient thermistor (Negative Temperature Coefficient, NTC), a thermocouple, a thermistor, a resistance temperature detector (Resistance Temperature Detector, RTD), a digital thermometer IC and the like.

Step S102, performing temperature compensation on the real-time sensing temperature through a pre-generated current temperature compensation value of the temperature sensing component to generate a compensation temperature.

In one embodiment of the application, the real-time sensing temperature can be subjected to temperature compensation through the pre-generated current temperature compensation value of the temperature sensing assembly, so that more accurate compensation temperature is generated. Temperature compensation is used to reduce the effect of temperature on the measurement results. Due to the temperature characteristics of the temperature sensing assembly itself and the change of the ambient temperature, a certain deviation may occur to the measured temperature. Therefore, by generating the temperature compensation value of the temperature sensing assembly in advance, the actual temperature can be reflected more accurately. Specifically, compensation values of the temperature sensing component at different temperatures can be pre-generated in software, and corresponding compensation calculation is performed according to the current temperature during real-time detection. Therefore, the compensation temperature is closer to the actual water temperature, and the accuracy and the reliability of measurement are improved.

Furthermore, other techniques besides temperature compensation may be employed to improve the accuracy of the measurement. For example, filtering algorithms may be employed to smooth the real-time sensed temperature to reduce the effects of noise and fluctuations. The error can be reduced by a method of averaging through multiple measurements, and the stability of the measurement is improved. The actual temperature can be reflected more accurately by generating the current temperature compensation value of the temperature sensing component in advance and carrying out temperature compensation, and the accuracy and the reliability of measurement are improved. The water temperature condition can be better mastered and corresponding control decisions can be made on the user level.

The temperature compensation is carried out on the real-time sensing temperature through a pre-generated current temperature compensation value of the temperature sensing component, and before the compensation temperature is generated, the method further comprises the steps of: temperature balance judgment is carried out on the burning process of the first power-on water burning, and after the temperature balance, the current boiling temperature is determined; and determining the current temperature compensation value of the temperature sensing assembly according to the current boiling temperature and the theoretical boiling temperature which is acquired in advance.

In an embodiment of the present application, when a user uses the water heating device for the first time, the water is heated by powering on for the first time, heating is continued, temperature balance judgment is performed in the heating and recording process, the temperature is continuously increased, and after the temperature reaches the balance, the stable temperature at this time, that is, the current boiling temperature is recorded. The current temperature compensation value of the temperature sensing assembly is obtained through the current boiling temperature and the pre-acquired theoretical boiling temperature, and the theoretical boiling temperature can be 100 ℃. In general, there are two cases of the current boiling temperature and the theoretical boiling temperature, one is that the current boiling temperature is greater than the theoretical boiling temperature, and the other is that the current boiling temperature is less than the theoretical boiling temperature, so that the absolute value of the difference between the current boiling temperature and the theoretical boiling temperature is taken to obtain the current temperature compensation value.

After determining the current boiling temperature, the method further comprises: when the current boiling temperature is smaller than the theoretical boiling temperature, periodically increasing the current boiling temperature according to a preset temperature increasing rule to determine a real-time display temperature, and when the real-time display temperature is the theoretical boiling temperature, stopping heating; and when the current boiling temperature is not less than the theoretical boiling temperature, the heating is stopped.

In one embodiment of the present application, when a user first powers up to boil water, the boiling temperature is displayed for two cases of the current boiling temperature and the theoretical boiling temperature, in different cases. Under the condition that the current boiling temperature is not less than the theoretical boiling temperature, namely the current boiling temperature is greater than 100 ℃ or equal to 100 ℃, the display temperature is limited to be 100 ℃ because the display threshold of the display temperature is 100 ℃, and under the current condition, the display temperature is 100 ℃, the display temperature meets the requirements, the heating can be directly stopped, the first power-on water boiling process is completed, and the boiling temperature display of 100 ℃ is carried out.

In the case that the current boiling temperature is less than the theoretical boiling temperature, that is, the current boiling temperature is less than 100 degrees celsius at this time, the current boiling temperature may be affected by the high altitude or limited by the temperature sensing error of the temperature sensing assembly, so there is a case of less than 100 degrees celsius. In this case, the display is usually performed based on the current boiling temperature, but cannot be performed to 100 ℃. In order to ensure that the display temperature reaches 100 ℃, a pseudo temperature mode can be set, the current boiling temperature is periodically increased according to a preset temperature increasing rule in the pseudo temperature mode, and the real-time display temperature is determined. That is, the temperature is increased by a specified degree every fixed time period based on the current boiling temperature to reach 100 degrees celsius. After reaching 100 degrees celsius, the heating mode is pushed out.

Before the periodic increment is performed according to the preset temperature increment rule, the method further comprises the following steps: acquiring the heating speed of the water heating device; determining a heating time length corresponding to the unit temperature value through the heating speed, so as to determine a temperature increasing period according to the heating time length; based on the temperature increment period, the unit temperature values are sequentially incremented to determine the temperature increment rule.

In one embodiment of the present application, in the pseudo-temperature mode, the determination of the temperature increment rule may be determined by a heating parameter of the water heating device. First, the heating rate of the water boiling device is obtained. In general, the heating rate of the water boiling device depends on a plurality of factors, including the power, the thermal efficiency, the ambient temperature of the water boiling device, and the like; the higher the power is, the faster the heating speed of the water heating device is, but the power consumption is correspondingly increased; the heat efficiency is also an important factor influencing the heating speed, and the high-efficiency heat conduction and heat energy utilization can heat more quickly; ambient temperature also has an effect on the heating rate, and lower ambient temperatures may require longer times to reach the desired heating temperature. In the embodiment of the application, experimental tests can be considered, parameters such as heating time, initial temperature of water, ambient temperature and the like are recorded in the test process, and a tool such as a thermometer is used for obtaining the temperature change of the water. From the recorded data, the heating rate of the heating device can be calculated. The pertinence and the accuracy of the heating time of the heating device can be ensured by a test mode.

Then, by the heating speed, a heating period corresponding to the unit temperature value, that is, a heating period required for heating every 1 degree celsius is determined, and the heating period is determined as a temperature increasing period, for example, 5 seconds are required for heating every 1 degree celsius. The unit temperature values are sequentially incremented through a temperature increment period to determine a temperature increment rule, i.e., 1 degree celsius per 5 seconds, and such advance line temperature increments until 100 degrees celsius are reached. The temperature increment rule is adjusted according to the actual heating speed of the water boiling device, so that the accurate control of the heating process can be realized, the display temperature fluctuation or inaccuracy caused by the too high or too low heating speed can be avoided, and the temperature can be ensured to be steadily and accurately increased to the required temperature.

The temperature compensation is carried out on the real-time sensing temperature through a pre-generated current temperature compensation value of the temperature sensing component, and the compensation temperature is generated, and specifically comprises the following steps: determining the proportion to be compensated by the current temperature compensation value and the theoretical boiling temperature which is obtained in advance; and carrying out temperature compensation on the real-time sensing temperature according to the proportion to be compensated, and generating a compensation temperature.

In one embodiment of the present application, the proportion to be compensated is determined by the ratio of the current temperature compensation value and the theoretical boiling temperature obtained in advance. And carrying out temperature compensation on the real-time sensing temperature according to the proportion to be compensated, and generating a compensation temperature. Assume that the current boiling temperature is T _{Boiling of} Theoretical boiling temperature is 100 ℃, at T _{Boiling of} <At 100 ℃, the current temperature compensation value Δt=100-T _{Boiling of} Compensating 0-DeltaT according to 0-100deg.C to obtain compensation temperature T _{After compensation} Is T _{After compensation} ＝T _{Real-time perception} * (1+ΔT/100), where T _{Real-time perception} The temperature sensing device senses the temperature in real time for the temperature sensing component. At T _{Boiling of} >At 100 ℃, the current temperature compensation value Δt=t _{Boiling of} -100, compensating 0 to-DeltaT according to 0 to 100 ℃, and calculating the compensation temperature to be T _{After compensation} ＝T _{Real-time perception} *(1-ΔT/100)、T _{Real-time perception} The temperature sensing device senses the temperature in real time for the temperature sensing component.

Through the technical scheme, the temperature is sensed in real time through compensation, measurement errors caused by the influence of the ambient temperature, the aging of the water heating device or other factors can be reduced, the temperature after compensation is closer to the real water temperature, and the measurement accuracy and the display requirement of the boiling temperature are improved. Accurate temperature measurement enables the water boiling device to better meet the demands of users, and the users can obtain more stable and consistent results no matter making tea, boiling coffee or boiling water, thereby enhancing the satisfaction degree of the users. Because the accuracy of temperature measurement is improved, the water heating device can control the heating process more accurately, unnecessary energy waste is avoided, electric power is saved, and the energy cost of a user is reduced; the accurate temperature measurement and heating control can reduce excessive thermal stress and mechanical stress on the internal elements of the water heating device, thereby prolonging the service life of the water heating device; by compensating the real-time sensing temperature, faults or abnormal conditions caused by inaccurate temperature measurement can be reduced, and the reliability and stability of the water heating device are enhanced; the method can carry out self-adaptive adjustment according to different environmental conditions and states of the water heating device, and ensure that accurate temperature measurement results can be obtained under various conditions. The calibration can be carried out before the water heating device leaves the factory, and necessary compensation adjustment is automatically carried out in the use process, so that the calibration process of the water heating device is simplified, and the requirement on user maintenance is reduced.

Step S103, displaying the real-time temperature of the burning process according to the compensation temperature, judging the temperature balance of the burning process, and determining the balanced compensation temperature after the temperature balance.

In one embodiment of the present application, the real-time temperature display is performed on the recording process according to the compensated temperature, and the following description will take the temperature sensing component as NTC as an example, and assume that the temperature of the recording process measured by the temperature sensing NTC is 25 degrees celsius, and the current boiling temperature corresponding to the water boiling device is 95 degrees celsius, then the following formula T is performed _{After compensation} ＝T _{Real-time perception} * When the compensation temperature corresponding to 25 ℃ is 25 (1+5/100) =26.25 ℃, the temperature is 26.25 ℃ when the temperature sensing NTC measures 25 ℃. When the temperature measured by the temperature sensing NTC is 95 degrees celsius, 95 x (1+5/100) =99.75 is shown as 99.75 degrees celsius.

In one embodiment of the present application, a particular point may be considered to be in a temperature equilibrium state when its temperature value remains constant for a period of time without significant fluctuations or changes. Under different altitudes, the water temperature can be kept unchanged after the water is boiled, and the temperature sensing temperature of the temperature sensing component can be kept unchanged at the moment, so that the characteristic can be utilized to judge that the water is in a boiling state and the temperature balance is achieved. And (3) carrying out temperature balance judgment on the burning process, and determining a balance compensation temperature after temperature balance, wherein the balance compensation temperature is a temperature value after compensating the temperature actually measured by the temperature sensing assembly.

Step S104, displaying the boiling temperature through balancing the compensation temperature.

By means of the equilibrium compensation temperature, the boiling temperature is displayed, and the method specifically comprises the following steps: when the balance compensation temperature is smaller than a preset target boiling display temperature, periodically increasing the balance compensation temperature according to a preset temperature increasing rule to increase the balance compensation temperature to the target boiling display temperature, and displaying the boiling temperature; and when the balance compensation temperature is not less than the target boiling display temperature, displaying the boiling temperature according to the target boiling display temperature.

In one embodiment of the present application, the temperature balance judging process corresponding to the burning process has two cases, one is a case that the balance compensation temperature is smaller than the preset target boiling display temperature, and the other is a case that the balance compensation temperature is not smaller than the preset target boiling display temperature, where the target boiling display temperature may be 100 ℃.

When the equilibrium compensation temperature is less than the target boiling display temperature, that is, when the temperature is not 100 ℃, the temperature equilibrium state is entered, when the temperature is not 100 ℃, the water is boiled, the pseudo temperature mode is entered, the equilibrium compensation temperature after the equilibrium is periodically increased according to a preset temperature increasing rule to increase to the target boiling display temperature, and the temperature display is performed according to the target boiling display temperature. The boiling temperature of the elevation of 1500 m-0 m is 95-100, and according to the requirements of the product temperature precision + -5 and the requirement of a user on the water can be burnt to 100 ℃, so that the temperature of the boiled water can be ensured to be displayed to 100 ℃ below 1500 m.

Before the periodic increment is performed according to a preset temperature increment rule, the heating speed of the water heating device can be obtained, and the heating time length corresponding to the unit temperature value can be calculated through the heating speed. A temperature increment period is determined according to the heating duration, for example, here set to increase by 1 degree celsius every 5 seconds, and the unit temperature values are sequentially incremented according to the temperature increment period to determine the temperature increment rule.

The equilibrium compensation temperature is periodically increased according to a preset temperature increasing rule so as to increase to the target boiling display temperature, and after the boiling temperature display is performed, the method further comprises the steps of: determining a temperature update compensation value according to the equilibrium compensation temperature and the current temperature compensation value; and determining an actual measured temperature compensation proportion through the temperature updating compensation value and the target boiling display temperature so as to carry out temperature compensation on the actual measured temperature in the next burning process based on the actual measured temperature compensation proportion.

In one embodiment of the present application, if the equilibrium compensation temperature is less than the target boiling display temperature, the temperature is already in equilibrium before 100 degrees celsius, indicating that there is a problem with the compensation temperature being too small. The problem of creating too small a compensation temperature may be related to the temperature sensing assembly and also to the operating environment of the water heating device. In this case, the current temperature compensation value needs to be corrected in order to facilitate the display of the boiling temperature in the next burning process. The current temperature compensation value may be corrected by: firstly, determining a temperature value to be compensated according to the balance compensation temperature and the target boiling display temperature, and determining a temperature update compensation value according to the sum of the temperature value to be compensated and the current temperature compensation value. For example, the equilibrium compensation temperature is 97 degrees celsius, and the difference between 100 degrees celsius and 97 degrees celsius is calculated, so that the temperature value to be compensated is 3 degrees celsius. Assuming that the current temperature compensation value is 5 ℃, determining the sum of the temperature value to be compensated of 3 ℃ and the current temperature compensation value of 5 ℃ as a temperature update compensation value. And calculating the actual measured temperature compensation proportion according to the ratio of the temperature updating compensation value to the target boiling display temperature so as to carry out temperature compensation on the actual measured temperature in the next burning process based on the actual measured temperature compensation proportion.

When the equilibrium compensation temperature is not less than the target boiling display temperature, the temperature is just balanced when the equilibrium compensation temperature is equal to the target boiling display temperature, namely when the equilibrium compensation temperature reaches 100 ℃, and the equilibrium compensation temperature is the target boiling display temperature under the condition, the boiling temperature is displayed according to the target boiling display temperature, and the heating is stopped, so that the heating process is completed. When the equilibrium compensation temperature is greater than the target boiling display temperature, that is, the compensation temperature reaches equilibrium after reaching 100 degrees celsius, that is, the equilibrium compensation temperature is greater than 100 degrees celsius, and since the display temperature is limited to 100 degrees celsius at maximum, the display is performed according to the target boiling display temperature of 100 degrees celsius no matter what the equilibrium compensation temperature is.

After the boiling temperature display is performed according to the target boiling display temperature, the method further comprises: continuously heating according to a preset heating period, and executing a temperature balance judging process; monitoring the temperature balance judging process in real time to acquire a plurality of specified compensation temperatures in the heating period; according to the specified compensation temperatures, temperature change analysis is carried out, and the temperature change state in the heating period is determined; when the temperature change state in the heating period is a temperature stable state, heating is stopped; when the temperature change state in the heating period is a temperature rising state, acquiring a specified balance compensation temperature in the heating period; and updating the current temperature compensation value through the appointed equilibrium compensation temperature, and determining an updated temperature compensation value so as to perform temperature compensation on the sensing temperature in the next burning process through the updated temperature compensation value.

In one embodiment of the present application, when the equilibrium compensation temperature is not less than the target boiling display temperature, continuous heating is performed according to a preset heating period, and the temperature equilibrium judgment process is continued in the process.

Specifically, according to the specified compensation temperatures, performing temperature change analysis, and before determining the temperature change state in the heating period, further includes: and acquiring a temperature increment period corresponding to the water heating device, which is generated in advance, so as to determine the heating period based on the temperature increment period.

In one embodiment of the present application, the heating period is determined according to a temperature increment period corresponding to the water heating device, where the temperature increment period is a heating period required for increasing the temperature by 1 degree celsius, and the heating period is determined according to a specified multiple of the heating period. It may be 3 times, for example, when the temperature increment period is 5 seconds for heating every 1 degree celsius increment, the corresponding heating period may be set to 15 seconds, that is, the heating is continued for 15 seconds, so as to perform the temperature balance determination.

In one embodiment of the present application, continuous heating is performed according to a heating cycle, the temperature during the temperature balance determination is monitored in real time, and a plurality of specified compensation temperatures within 15 seconds of the heating cycle are collected. And carrying out temperature change analysis on the specified compensation temperatures within 15 seconds according to the specified compensation temperatures, and determining the temperature change state in the heating period. The temperature change state herein includes a temperature steady state, i.e., a state in which the temperature does not rise during the heating period, and a temperature rising state, i.e., a state in which the temperature rises during the heating period.

When the temperature change state in the heating cycle is a temperature steady state, which indicates that an equilibrium state has been reached at 100 degrees celsius, the heating is exited. When the temperature change state in the heating period is a temperature rising state, it is indicated that there is still a temperature rising after reaching 100 degrees celsius, that is, the temperature balance point is greater than 100 degrees celsius, and at this time, it is considered that the temperature compensation is excessive, and the temperature balance judgment needs to be performed again in order to perform the temperature compensation.

And when the temperature balance judgment is carried out, acquiring a specified balance compensation temperature in the heating period, namely the compensation temperature after balance. And updating the current temperature compensation value by specifying the balance compensation temperature, and determining an updated temperature compensation value so as to perform temperature compensation on the perceived temperature in the next burning process by the updated temperature compensation value.

Updating the current temperature compensation value through the specified equilibrium compensation temperature, and determining an updated temperature compensation value, specifically comprising: determining a compensated temperature deviation adjustment value by the specified equilibrium compensation temperature and the target boiling display temperature; and determining the updated temperature compensation value by the compensation temperature deviation adjustment value on the basis of the current temperature compensation value.

In one embodiment of the present application, the compensation temperature deviation adjustment value is determined according to the difference between the specified equilibrium compensation temperature and the target boiling display temperature, for example, if the specified equilibrium compensation temperature is 103 degrees celsius, the compensation temperature deviation adjustment value is calculated to be 103-100=3 degrees celsius, and if the current temperature compensation value is 5 degrees celsius, since the situation of excessive compensation is caused after the current temperature compensation value is compensated for 5 degrees celsius, the compensation temperature deviation adjustment value is reduced by 3 degrees celsius on the basis of 5 degrees celsius, so as to obtain an updated temperature compensation value, namely, 2 degrees celsius, and according to the updated temperature compensation value, the temperature compensation is performed on the sensing temperature of the next water heating process. On the basis of ensuring normal display of the boiling temperature in the current burning process, the temperature compensation condition is monitored according to the temperature change condition in the current burning process, and abnormal compensation is corrected in time, so that the boiling temperature in the next burning process is conveniently displayed.

According to the technical scheme, according to the requirements of the product on the temperature precision +/-5 and the requirement that water can be burned to 100 ℃ by a user, the temperature of the boiled water can be ensured to be displayed to 100 ℃ by the method provided by the embodiment of the application under the altitude of 1500 m; in addition, the temperature sensing difference of the temperature sensing assembly after the water is boiled, which is generated due to the consistency deviation of the temperature sensing assembly body and the installation position of the water heating device, can be avoided, and the condition that the temperature is displayed abnormally due to the temperature sensing difference is avoided; in addition, the water heating device can influence the temperature sensing temperature of the temperature sensing component after dry heating or long-term use, so that the water can be ensured to be in a boiling state after the temperature sensing temperature of the temperature sensing component is changed, and the boiling temperature can be normally displayed.

Fig. 2 is a schematic flow chart of a boiling temperature display method of another water boiling device according to an embodiment of the present application, as shown in fig. 2, including the following steps:

the first step, electrifying to burn water for the first time, continuously heating, and recording the boiling temperature T when the temperature is no longer rising to reach the equilibrium _{Boiling of} And judge the boiling at this timeTemperature is related to 100 degrees celsius. If T _{Boiling of} <And (3) entering a pseudo-temperature stage, wherein the display temperature rises by 1 ℃ every 5s, and after the display temperature reaches 100 ℃, the heating is stopped. If T _{Boiling of} And (5) directly exiting the heating if the temperature is more than or equal to 100 ℃. It should be noted that if the NTC temperature is greater than 100 ℃, a maximum of 100 ℃ is displayed as the temperature limit.

Second, according to recorded T _{Boiling of} And (5) performing temperature compensation. If T _{Boiling of} <100 ℃, then Δt=100-T _{Boiling of} Then according to 0-100 deg.C, compensating 0-delta T, calculating actual temperature as T _{After compensation} ＝T _NTC *(1+ΔT/100)、T _NTC Is the current NTC temperature. If T _{Boiling of} >100 ℃, Δt=t _{Boiling of} -100, then according to 0-100 deg.C, compensating 0-delta T, calculating actual temperature as T _{After compensation} ＝T _NTC *(1-ΔT/100)、T _NTC Is the current NTC temperature.

Third step, after the second time of water heating, displaying T _{After compensation} And heating the temperature, and judging the temperature balance in the burning process. If T _{After compensation} <At 100, the temperature has equilibrated T _Balancing It is explained that when the temperature does not reach 100 ℃, the water has been boiled, and the pseudo-temperature stage is entered, the display temperature rises by 1 ℃ every 5s, and when the display temperature reaches 100 ℃, the heating is exited. At this time T _{Boiling of} ＝T _Balancing The temperature compensation according to the second step is performed again. If T _{After compensation} And when the temperature is not balanced or is equal to or higher than 100 ℃, heating is continued for 15s under the condition that the temperature is not balanced or is equal to or higher than 100 ℃. During the heating continued for 15 seconds, the temperature was monitored, and if the temperature did not rise, the heating was exited. If the temperature rises, the compensation temperature is considered to be too high, the temperature balance is judged again, and when the temperature does not rise, the boiling point T is recorded _Balancing The temperature compensation according to the second step is performed again. The third step is repeated every time water is boiled.

At different altitudes, the water temperature can be kept unchanged after the water is boiled, and the temperature of the temperature sensing NTC can be kept unchanged at the moment, so that whether the water is boiled or not can be judged by utilizing the characteristic, and the temperature balance is achieved. In the first water heating process, namely the first power-on water heating, if the temperature after balancing is less than 100 ℃, the temperature enters a pseudo-temperature mode, namely the temperature is displayed to rise by 1 degree every 5s, and the heating is stopped after the temperature reaches 100 ℃. And temperature compensation is carried out by utilizing the deviation between the measured NTC value after temperature balance and the display temperature of 100 ℃, so that the water boiling for the second time and later can be normally displayed to 100 ℃. After temperature compensation, if the water is heated to 100 ℃, heating is continued for a period of time, whether the NTC temperature rises is determined, the boiling temperature can be updated in real time, and the problem that the boiling point only drops and does not rise is avoided. In contrast, after the temperature compensation, if the water is not burned to 100 ℃, the boiling temperature can be updated through the judgment of temperature balance. And the temperature was displayed to 100 ℃ using a pseudo temperature display.

The embodiment of the application also provides two working condition examples corresponding to the first power-on water heating, when the first working condition is the altitude of 1500 meters, the temperature of water in the kettle and the temperature sensing component NTC can only be sensed to 95 ℃, but the display temperature needs to be displayed to 100 ℃. Under the second working condition, due to the consistency difference of the NTCs, when the temperature of the NTC is 100 ℃, the perceived temperature of the temperature sensing component NTC is 102 ℃.

In the first working condition, the display temperature may be set to the actual NTC temperature at the beginning of the temperature increasing stage, the display temperature being the same as the NTC temperature. After reaching 95 degrees celsius, the temperature is no longer changing, and the temperature equilibrium is reached, at which time the NTC temperature is no longer rising. After the temperature reaches equilibrium, the temperature is shown to rise 1 degree celsius every 5 seconds, and when the temperature reaches 100 degrees celsius, the heating mode is exited.

In the second working condition, in the initial temperature rising stage, the display temperature is the same as the temperature sensing temperature of the temperature sensing NTC, and after the temperature sensing temperature of the temperature sensing NTC reaches 100 ℃, the display temperature is maintained at 100 ℃ due to the temperature limitation of the maximum 100 ℃, and at the moment, the NTC temperature is still rising. After the NTC temperature reaches equilibrium, the heating is exited.

By adopting the technical scheme, the measurement error caused by the influence of the ambient temperature, the aging of the water heating device or other factors can be reduced by continuous heating and temperature compensation. The temperature after compensation is closer to the real water temperature, so that the accuracy of measurement is improved; the accurate temperature measurement enables the water heating device to better meet the demands of users, the users can obtain more stable and consistent results, and the satisfaction degree and trust feeling of the users are enhanced; because the accuracy of temperature measurement is improved, the equipment can control the heating process more accurately, and unnecessary energy waste is avoided; through continuous heating, temperature compensation and temperature balance judgment, faults or abnormal conditions caused by inaccurate temperature measurement can be reduced, and the reliability and stability of the water heating device are enhanced; the self-adaptive adjustment can be carried out according to different environmental conditions and equipment states, so that accurate temperature measurement results can be obtained under various conditions.
