Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking utensils, in particular to a heating control method of a tea bar machine. BACKGROUND

[0002] With the progress of science and technology and the improvement of people's living standards, people's requirements for cooking utensils are also getting higher and higher. Among them, the tea bar machine, as a cooking utensil for boiling water and tea, is widely loved by people because of its simple and beautiful appearance and convenient use.

[0003] The boiling point temperature of water is affected by air pressure, that is, when the heating device is in a high altitude area, the boiling point of water will be significantly lower than 100℃. If the tea bar machine always heats at a fixed heating temperature, the water heating device will always boil in a high altitude area, which may cause water overflow or dry burning, and also increase the consumption of electric energy, resulting in poor user experience.

[0004] The prior art discloses a boiling point recognition control method, which recognizes the boiling point temperature of the environment where the tea bar machine is located, instead of the original fixed boiling point method. For example, the boiling point recognition method mentioned in the prior art includes detecting temperature balance, temperature change rate, temperature jump and the like. Specifically, a method for determining the boiling point temperature is disclosed, which includes: automatically adjusting the duty cycle of the output power of the heating device, controlling the heating device to keep in communication with the external environment; detecting the current temperature value of the liquid during heating; determining whether the time required for the liquid to rise by X from the current temperature value is greater than or equal to the corresponding preset threshold value, if yes, the current temperature value is determined as the boiling point value of the liquid, if no, the current temperature value+X is taken as the current temperature value, and the determination of whether the time required for the liquid to rise by X from the current temperature value is greater than or equal to the corresponding preset threshold value is returned to be executed until the current temperature value+X is 100℃, and 100℃ is determined as the boiling point. The present scheme can automatically recognize the boiling point according to different altitudes.

[0005] However, the boiling point temperature of the liquid has a large difference with the increase of altitude when the altitude exceeds 2000m, and the large difference in boiling point temperature will affect the boiling or tea boiling effect of the tea bar machine. Therefore, most of the tea bar machines on the market can only guarantee the best boiling effect below an altitude of 2000m, and may have problems such as over-boiling or poor boiling effect in areas above an altitude of 2000m, for example, water spraying may occur during boiling point recognition, resulting in poor user experience.

[0006] Meanwhile, some tea bar machines in the prior art can recognize altitudes, but the tea bar machines in the prior art mostly adopt a single altitude recognition mode to recognize altitudes of regions where the tea bar machines are located, and have problems of high cost or complex recognition process and long time, for example, adding other auxiliary sensors and components in the recognition process, which increases the cost of the tea bar machine, or completing the altitude recognition through the first use of the controllable silicon to reduce the power and temperature feedback, but for regions with altitudes greater than 2000m, there may be problems of complex recognition process and long recognition time, which may affect the user experience.

[0007] Therefore, the prior art needs to be further improved and promoted. SUMMARY

[0008] The application provides a heating control method of a tea bar machine to solve at least one of the above technical problems.

[0009] The technical scheme adopted by the application is as follows:

[0010] The application provides a heating control method of a tea bar machine, comprising:

[0011] The determination stage: continuously obtaining a plurality of temperature sampling values, when the temperature sampling values meet a first preset condition, obtaining a current temperature sampling value, determining that the current temperature sampling value is lower than a first temperature threshold, controlling the tea bar machine to enter a manual calibration stage, otherwise, entering an altitude automatic recognition stage;

[0012] The manual calibration stage: controlling the display device of the tea bar machine to enter an altitude manual setting interface, calibrating the preset boiling point temperature of the tea bar machine according to the input information of the user, and obtaining the actual boiling point temperature of the tea bar machine according to the calibration result.

[0013] The altitude automatic recognition stage: recording the effective number of times that the temperature sampling values continuously meet the first preset condition, and determining the actual boiling point temperature of the tea bar machine according to the comparison result of the effective number of times and the preset number of times and the recorded temperature sampling values.

[0014] As an embodiment of the application, in the manual calibration stage, the corresponding actual boiling point temperature is obtained through the altitude information input by the user to control the heating process of the tea bar machine, and when the heating temperature meets a second preset condition in the heating process, the heating process is ended and the tea bar machine enters the altitude automatic recognition stage.

[0015] As an embodiment of the application, the second preset condition is specifically that the heating temperature of the tea bar machine cannot reach the actual boiling point temperature in N consecutive heating processes, or the first temperature difference AT1 between the heating temperature and the actual boiling point is greater than a preset threshold when the heating process is exited.

[0016] As an embodiment of the present application, a plurality of temperature sampling values are continuously acquired, and when the temperature sampling values satisfy a first preset condition, a current temperature sampling value is acquired, comprising:

[0017] A plurality of temperature sampling values are continuously acquired, and a second temperature difference AT2 between a current temperature sampling value Tn and a previous temperature sampling value Tn-1 is periodically acquired, and it is determined whether the second temperature difference AT2 satisfies a first preset condition;

[0018] When the first preset condition is satisfied, it is determined that the tea bar machine is in a high-altitude environment, and when the current temperature sampling value Tn is lower than a first temperature threshold T1, the tea bar machine is controlled to enter a manual calibration stage.

[0019] As an embodiment of the present application, the tea bar machine enters an altitude automatic identification stage when one of the following conditions is satisfied:

[0020] The second temperature difference AT2 satisfies the first preset condition, and the current temperature sampling value Tn is higher than the first temperature threshold T1;

[0021] Alternatively, the second temperature difference AT2 satisfies the first preset condition, and the current temperature sampling value is lower than the first temperature threshold T1, and the user actively exits the manual calibration stage;

[0022] Alternatively, the second temperature difference AT2 satisfies the first preset condition, and the current temperature sampling value Tn is lower than the first temperature threshold T1, and the input information is not received within a first time threshold t1.

[0023] As an embodiment of the present application, when the tea bar machine enters the altitude automatic identification stage:

[0024] When it is detected that the temperature sampling values satisfy the first preset condition, the current heating power of the heating device is reduced until the second temperature difference AT2 between the temperature sampling value Tn and the previous temperature sampling value Tn-1 continuously acquired for M times satisfies the first preset condition;

[0025] The minimum temperature value in the temperature sampling values is set as a first temporary altitude boiling point.

[0026] As an embodiment of the present application, when the tea bar machine acquires the first temporary altitude boiling point and the heating process is started, the altitude automatic identification stage is repeatedly performed to obtain a second temporary altitude boiling point;

[0027] If the difference between the first temporary altitude boiling point and the second temporary altitude boiling point does not exceed a preset boiling point difference, the minimum value between the first temporary altitude boiling point and the second temporary altitude boiling point is set as an actual boiling point temperature.

[0028] As an embodiment of the present application, when the temperature sampling value does not satisfy the first preset condition for M times continuously, it is determined that the tea bar machine is in a plain environment, and a preset boiling point temperature is called as the actual boiling point temperature of the tea bar machine.

[0029] As an embodiment of the present application, in the determination stage, when the current temperature sampling value Tn is greater than or equal to the preset boiling point temperature, it is determined that the tea bar machine is in a plain environment, the determination stage is ended, and a preset boiling point temperature is called as the highest heating temperature of the tea bar machine in the current environment.

[0030] As an embodiment of the present application, the determination stage further comprises a preheating stage before the determination stage: receiving a control instruction of a user, controlling the tea bar machine to run at full power and obtaining a real-time temperature value, if the real-time temperature value is greater than a second temperature threshold, continuing to heat for more than a second time threshold, and controlling the tea bar machine to enter the determination stage.

[0031] Due to the above technical solutions, the present application has the following technical effects:

[0032] 1. The heating control method of the tea bar machine provided by the present application, in the determination stage, a plurality of temperature sampling values are obtained continuously, and it is judged whether the temperature sampling values satisfy a first preset condition. Through the control method, it can be determined whether the tea bar machine is in a non-plain area, and when it is determined that the tea bar machine is in a high-altitude area, the real-time temperature value is used to determine whether the tea bar machine enters a manual calibration stage or an altitude automatic identification stage, so that the altitude identification procedure for determining the current working condition of the tea bar machine can be quickly determined, the efficiency of altitude identification is greatly improved, the practicability of the tea bar machine is improved, and the user experience is improved.

[0033] 2. When the temperature sampling value satisfies the first preset condition and the real-time temperature sampling value is lower than a first temperature threshold, the tea bar machine is controlled to enter the manual calibration stage. The display device enters the manual calibration stage, and the user can input the current altitude information in a manual intervention manner, so that the heating function of the tea bar machine can be quickly corrected, the time of the altitude identification process is saved to a certain extent, and additional auxiliary sensor devices and the like are not needed in the identification process, thereby saving the production cost of the tea bar machine. Moreover, the altitude of the area where the tea bar machine is located is determined by manual intervention, the identification process is simple, the identification time is short, the heating efficiency of the tea bar machine is improved, the phenomenon of water spraying during the boiling point identification process of the tea bar machine in a high-altitude area (such as above 2000m) is avoided, the practicability of the tea bar machine is improved, and the user experience is improved.

[0034] 3. After obtaining the actual boiling point temperature, the obtained actual boiling point temperature can be further adjusted and calibrated according to the actual working conditions during the heating process to prevent dry burning caused by a low actual boiling point temperature or insufficient boiling caused by a high actual boiling point temperature, thereby further improving the accuracy of boiling point identification and the user experience.

[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0044] like Figure 1 As shown, this application provides a heating control method for a tea bar machine, including:

[0045] determination stage: continuously acquire a plurality of temperature sampling values, when the temperature sampling values meet a first preset condition, acquire a current temperature sampling value, determine that the current temperature sampling value is lower than a first temperature threshold value, control the tea bar machine to enter a manual calibration stage, otherwise, enter an altitude automatic identification stage;

[0046] manual calibration stage: control a display device of the tea bar machine to enter an altitude manual setting interface, calibrate a preset boiling point temperature of the tea bar machine according to input information of a user, and acquire an actual boiling point temperature of the tea bar machine according to a calibration result;

[0047] altitude automatic identification stage: record an effective number of times that the temperature sampling values continuously meet the first preset condition, and determine the actual boiling point temperature of the tea bar machine according to a comparison result of the effective number of times and a preset number of times and the recorded temperature sampling values.

[0048] In the above, by entering the determination stage before the heating process of the tea bar machine, it is determined whether the temperature sampling values meet the first preset condition, and it is determined that the tea bar machine is currently located in an altitude environment. When the first preset condition is met, that is, the tea bar machine is located in a non-plain area, subsequent steps are performed, that is, by comparing the current temperature sampling value with the first temperature threshold value, it is determined that the tea bar machine enters the manual calibration stage or the altitude automatic identification stage. Specifically, when the current temperature sampling value exceeds the first temperature threshold value, it is determined that the tea bar machine is located in a lower altitude area, for example, below an altitude of 2000 m. At this time, the altitude automatic identification stage is entered, and the actual boiling point temperature of the tea bar machine is automatically acquired. When the tea bar machine is located in a higher altitude area, that is, in an environment above an altitude of 2000 m, the manual calibration stage is entered, and the preset altitude boiling point is calibrated according to the input information of the user to acquire the final actual boiling point temperature. In this application, by judging the specific altitude environment in which the tea bar machine is currently located, the altitude identification procedure for determining the current working condition of the tea bar machine is quickly determined, which greatly improves the efficiency of altitude identification, solves the problems of high cost or complex identification process and long time in the process of identifying the altitude of the area where the tea bar machine is located by a single altitude identification method, and avoids the water spraying phenomenon that occurs in the automatic boiling point identification process of the tea bar machine in a high altitude area, thereby improving the practicality and user experience of the tea bar machine.

[0049] The embodiment of the present application specifically provides a heating control method of a tea bar machine, which includes the following stages:

[0050] preheating stage:

[0051] Reference Figure 2, the control instruction of the user is received, the tea bar machine runs the heating device at full power and acquires a real-time temperature value, if the real-time temperature value is greater than a second temperature threshold T2 preset in the tea bar machine and the time of continuing heating at full power exceeds a second time threshold t2, the tea bar machine ends the preheating stage and enters a subsequent determination stage for determining an actual boiling point temperature.

[0052] In this stage, before the altitude judgment and boiling point identification, the heating temperature at the beginning of the determination stage is increased through preheating to shorten the duration of the determination stage and improve the efficiency of altitude identification. The second time threshold t2 is a preset constant value, which is positively correlated with the reaction time of the temperature detection member for detecting the heating temperature. Specifically, the second time threshold t2 is the maximum reaction time of the temperature detection member. In the specific implementation of the embodiment, the second temperature threshold T2 is an altitude identification starting temperature. When the tea bar machine heats at full power with the second temperature threshold T2 as the starting temperature, the real-time temperature value after t2 time needs to reach the boiling point value under an altitude of 5000m (i.e. 83 degrees Celsius) as the standard, and the specific value of the second temperature threshold T2 is set in combination with the size of the second time threshold t2.

[0053] Determination stage:

[0054] The sampling module in the tea bar machine is controlled to continuously acquire a plurality of temperature sampling values. When the temperature sampling values meet a first preset condition, a current temperature sampling value T n is acquired. n If the current temperature sampling value T n is determined to be lower than a first temperature threshold T1, the tea bar machine enters a manual calibration stage, otherwise it enters an altitude automatic identification stage.

[0055] Specifically, as shown in Figure 3 , the temperature sampling value is the water temperature in the kettle during the heating process of the tea bar machine. The current temperature sampling value T n is the latest acquired temperature sampling value when the acquired temperature data meets the first preset condition. By comparing the current temperature sampling value T n with the preset first temperature threshold T1, it is determined whether the tea bar machine enters the manual calibration stage or the altitude automatic identification stage. Specifically, the first temperature threshold T1 in the embodiment is the boiling point value under an altitude of 2000m, i.e. the current temperature sampling value T nWhen the time is less than T1, it is determined that the tea bar machine is in an environment above an altitude of 2000m, and the tea bar machine is prone to over-boiling or poor boiling effect. Therefore, a more accurate actual boiling point temperature needs to be used as a reference value for the heating process of the tea bar machine. At this time, the tea bar machine enters a manual calibration stage, and precise altitude information or boiling point information can be quickly obtained through manual operation of the user, greatly improving the speed of obtaining the actual boiling point temperature and reducing the phenomenon of over-boiling or poor boiling effect. At the same time, the phenomenon of water spraying that may occur in the process of automatic identification of altitude in an environment above an altitude of 2000m is avoided. That is, in the embodiment, by determining the altitude environment of the tea bar machine, a more suitable altitude identification method is selected to reduce abnormal working conditions of the tea bar machine and improve the efficiency of altitude identification and the user experience.

[0056] In detail, the temperature sampling period of the sampling module can be selected as 2S, 5S or 10s, etc. The sampling period is related to the rated power and capacity of the tea bar kettle, and therefore it can be limited according to the rated power and capacity of the tea bar kettle, that is, it can be set according to the temperature difference of normal boiling of a kettle of water and 1.1-1.5 times of the time length used for boiling water. In a specific embodiment, the rated capacity of the kettle is used to heat the water from 25℃ to 100℃, which takes 260S, and the time length for each degree of temperature rise is 260 / (100-25) = 3.47S. At this time, 5 seconds can be selected as the sampling period.

[0057] Manual calibration stage:

[0058] The display device of the tea bar machine is controlled to enter an altitude manual setting interface, the preset boiling point temperature T0 of the tea bar machine is calibrated according to the input information of the user, and the actual boiling point temperature of the tea bar machine is obtained according to the calibration result.

[0059] In the manual stage, the preset boiling point temperature T0 in the tea bar machine is quickly calibrated by recognizing the input information of the user to obtain the actual boiling point temperature in the current environment of the tea bar machine. The preset boiling point temperature T0 is the termination heating temperature in the plain area by default when the tea bar machine is used for the first time, and this value will be replaced by the actual boiling point temperature value obtained after manual calibration or automatic identification of altitude. The input information of the user includes altitude information, temperature information, location information, etc. to quickly obtain the boiling point value of the current region as the actual boiling point temperature, thereby reducing the waiting time of the user.

[0060] As an optional embodiment, in the manual calibration stage, the actual boiling point temperature corresponding to the altitude information input by the user is obtained, and the actual boiling point temperature is used as the highest heating temperature to control the heating process of the tea bar machine. When the heating temperature meets the second preset condition in the heating process, the heating process is ended and the tea bar machine enters the automatic identification stage of altitude.

[0061] Specifically, the embodiment further includes a heating process after the boiling point is identified, and a corresponding actual boiling point temperature is obtained through the altitude information of the user, wherein the corresponding relationship between the altitude information and the boiling point temperature is realized through formula calculation or preset table mapping, the highest heating temperature is the highest water temperature that can be reached under the current environment, which is generally the same as the boiling point value under the current environment, and the actual boiling point temperature obtained in the embodiment is taken as the highest heating temperature, so as to facilitate the control of the water temperature in the subsequent heating process of the tea bar machine. In the actual heating process after the boiling point is identified, it is detected that the heating temperature meets the second preset condition, that is, the highest heating temperature at this time is different from the current boiling point value in the region, and there are cases that the actual boiling point temperature obtained is greater than or less than the current boiling point value. When the actual boiling point temperature is greater than the current boiling point value by a large margin, long-time heating will cause over-boiling or even dry burning, and when the actual boiling point temperature is less than the current boiling point value by a large margin, the tea will not be boiled or will not be fully boiled, which affects the user's experience. That is, the actual boiling point temperature obtained through the input information of the user may not be applicable to the current region due to errors or misinputs, and at this time, the tea bar machine can be controlled to enter the altitude automatic identification stage to reacquire the actual boiling point temperature, or the manual calibration stage can be reset, and the user can be prompted to re-input the altitude information for secondary calibration.

[0062] In a specific embodiment of the present embodiment, the second preset condition is specifically that the heating temperature of the tea bar machine cannot reach the actual boiling point temperature in the continuous N heating processes, or the first temperature difference AT1 between the heating temperature and the actual boiling point is greater than a preset threshold when the heating process is exited.

[0063] In the above, when the actual boiling point temperature is greater than the current boiling point value, in the actual heating process, the heating temperature of the tea bar machine cannot reach the actual boiling point temperature all the time, which causes the tea bar machine to abnormally heat for a long time and cannot end the heating process. The determination that the heating temperature cannot reach the actual boiling point temperature can be realized through heating time, heating temperature change and the like. For example, a maximum heating time is set, which is related to the heating performance of the tea bar machine. When the heating time exceeds the maximum heating time, it is considered that the heating temperature cannot reach the actual boiling point temperature, the current heating process is ended, and the user is prompted to prevent the occurrence of safety problems such as dry burning caused by long-time continuous boiling; or the real-time change of the heating temperature is detected, the heating temperature is sampled through a sampling module, when the temperature difference between adjacent heating temperature sampling values is less than a certain value (for example, 1 degree Celsius), it is determined that the heating temperature reaches the current boiling point value, and when the latest heating temperature sampling value is less than the actual boiling point temperature, it is determined that the heating temperature cannot reach the actual boiling point temperature, the current heating process is ended, and the user is prompted.

[0064] When the actual boiling point temperature is less than the current boiling point value, the situation that the heating device is turned off when the water is not boiled or not fully boiled occurs, which causes the water to be not boiled, and affects the user's experience. Specifically, whether the actual boiling point temperature is less than the current boiling point value can be determined by the heating temperature when the tea bar machine exits the heating process. In a general heating process, the heating device is turned off after the heating temperature (i.e., the water temperature in the kettle) reaches the actual boiling point temperature, and the water continues to boil by residual heat or continues to boil for a delay. If the actual boiling point temperature is less than the current boiling point value at this time, the heating temperature will rise rapidly. Therefore, the heating temperature when the heating device is turned off is obtained and compared with the actual boiling point temperature. When the first temperature difference AT1 between the heating temperature and the actual boiling point is greater than a preset threshold, it means that the actual boiling point temperature is less than the current boiling point value, the current heating process is ended, and the user is prompted. The preset threshold in the embodiment can be set to 1-5 degrees Celsius.

[0065] It is easy to understand that when entering the manual calibration stage, the tea bar machine can remind the user to manually input or modify the current altitude information in a certain way. However, the user may not be near the tea bar machine at this time, or there may be other inconvenient manual input situations. Then, after a period of time, the manual calibration stage is automatically closed. The time setting for manual input maintenance can be determined according to the actual application scenario, for example, it can be set to 10s, 20s, etc.

[0066] As an optional embodiment, referring to Figure 4 The determination stage of the embodiment specifically includes:

[0067] A plurality of temperature sampling values are continuously collected, and a second temperature difference AT2 between the current temperature sampling value Tn and the previous temperature sampling value Tn-1 is periodically obtained. It is determined whether the second temperature difference AT2 satisfies a first preset condition.

[0068] When the first preset condition is satisfied, it is determined that the tea bar machine is in a high-altitude environment. When the current temperature sampling value Tn is lower than the first temperature threshold T1, the tea bar machine enters the manual calibration stage.

[0069] In the embodiment, whether the difference between the adjacent temperature sampling values meets the first preset condition in a certain sampling period is determined to determine the altitude environment in which the tea bar machine is located. When the first preset condition is met (i.e., less than the preset value), the tea bar machine is in a high-altitude environment. At this time, the size of the current temperature sampling value Tn and the first temperature threshold T1 is compared. When Tn is lower than T1, it is determined that the tea bar machine is currently in a higher altitude area, and the tea bar machine enters the manual calibration stage. Specifically, the first preset condition is that the second temperature difference AT2 between the current temperature sampling value Tn and the previous temperature sampling value Tn-1 is less than the preset value. In the embodiment, the preset value is 1 degree Celsius. The preset value is related to the rated power, rated capacity and thermal resistance sensitivity of the kettle. Under the same working condition, the smaller the temperature deviation, the smaller the preset value, and vice versa. The maximum should not exceed 3°C. It should be noted that the size of the first temperature threshold T1 and the relationship with the altitude have been described in the foregoing, and will not be repeated here.

[0070] In the embodiment, the altitude automatic identification stage is entered when one of the following conditions is met, as shown in the following table: Figure 3

[0071] The second temperature difference AT2 meets the first preset condition, and the current temperature sampling value Tn is higher than the first temperature threshold T1;

[0072] Alternatively, the second temperature difference AT2 meets the first preset condition, and the current temperature sampling value is lower than the first temperature threshold T1, and the user actively exits the manual calibration stage;

[0073] Alternatively, the second temperature difference AT2 meets the first preset condition, and the current temperature sampling value Tn is lower than the first temperature threshold T1, and the input information is not received within the first time threshold t1.

[0074] It can be understood that since the user's cooperation is required in the manual calibration stage, but when the manual calibration stage is started, the user may not receive the signal for reminding the user to input the altitude information issued by the tea bar machine, such as not being able to see the content output by the display panel for reminding the user, not being able to hear the sound issued by the tea bar machine for reminding the user, so as to not be able to input the current altitude information in time. However, if the tea bar machine cannot confirm the current altitude information during the heating process, it is likely that the heating effect will be poor due to the large error of the special boiling point at the altitude. Therefore, to avoid the above problems, the altitude automatic identification stage can also be entered when the user does not input the current altitude information, which can enable the tea bar machine to automatically identify the altitude and improve the heating effect of the tea bar machine to a certain extent.

[0075] Altitude automatic identification stage:

[0076] ​The effective number of times that the temperature sampling value continuously meets the first preset condition is recorded, and the actual boiling point temperature of the tea bar machine is determined according to a comparison result of the effective number of times and a preset number of times and the recorded temperature sampling value.

[0077] The effective number of times is a count value when the temperature sampling value continuously meets the first preset condition, and when a temperature sampling value that does not meet the first preset condition occurs, the data of the effective number of times is emptied and re-determined and counted; when the effective number of times accumulates to the preset number of times, the actual boiling point temperature is determined based on the acquired temperature sampling value; it should be noted that if the count of the effective number of times cannot meet the preset number of times in the automatic altitude identification stage, the automatic altitude identification stage is ended when the temperature sampling value reaches the preset boiling point temperature T0, and the value of the preset boiling point temperature T0 is assigned to the actual boiling point temperature.

[0078] Specifically, as shown in Figure 5 When it is detected that the temperature sampling value meets the first preset condition, the current heating power of the heating device is reduced until the second temperature difference ΔT2 between the temperature sampling value Tn collected continuously M times and the previous temperature sampling value Tn-1 all meet the first preset condition (i.e., less than a preset value), and the minimum temperature value in the temperature sampling value is set as the first temporary altitude boiling point.

[0079] For example, referring to Figure 6 When the second temperature difference ΔT2 meets the first preset condition for the first time, the tea bar machine is controlled to start to reduce the power to P1 (P1 can be set to 75% of the rated power), when the temperature difference ΔT2 meets the first preset condition for two consecutive times, the tea bar machine is controlled to reduce the power to P2 (P2 can be 50% of the rated power), when the temperature difference ΔT2 meets the first preset condition for three consecutive times, the tea bar machine is controlled to reduce the power to P3 (P3 can be set to 25% of the rated power), and then the temperature sampling value recorded in the identification process is compared, and the minimum value is stored as the first temporary altitude boiling point.

[0080] Meanwhile, after the tea bar machine obtains the first temporary altitude boiling point, when the heating process is started again, a secondary automatic altitude identification stage is entered to obtain a second temporary altitude boiling point; if the difference between the first temporary altitude boiling point and the second temporary altitude boiling point does not exceed a preset boiling point difference, the minimum value of the temporary altitude boiling point is set as the actual boiling point temperature.

[0081] In the above method, the data obtained in the boiling point identification process is taken as a first temporary altitude boiling point, and a second temporary altitude boiling point is obtained by using the same method before the next heating process starts. Whether the difference between the two temporary altitude boiling points is within a predetermined range is determined. If the difference is large, the second temporary altitude boiling point is taken as the actual boiling point, and the boiling point identification process is repeated until the difference is within the predetermined range. The minimum value of the two temporary altitude boiling points is taken as the actual boiling point temperature. The multiple identification and determination can avoid data errors in single identification, improve the accuracy of the tea bar machine in identifying the boiling point temperature, and improve the user experience.

[0082] In the embodiment, when the temperature sampling value does not satisfy the first predetermined condition for M consecutive times, it is determined that the tea bar machine is in a plain environment, the determination stage is ended, and a predetermined boiling point temperature is called as the actual boiling point temperature of the tea bar machine. Specifically, M can be 3, and the specific value of M is related to the temperature sampling period of the sampling module. In the embodiment, whether the tea bar machine is in a plain environment is determined in advance, the time for altitude determination and boiling point identification is further shortened, and the loss of electric energy resources and the waiting time of the user are reduced.

[0083] Further, in the determination stage or the preheating stage, when the current temperature sampling value Tn is greater than or equal to the predetermined boiling point temperature, it is directly determined that the tea bar machine is in a plain environment, the determination stage is ended, and the predetermined boiling point temperature is called as the highest heating temperature of the tea bar machine in the current environment.

[0084] In other embodiments of the present embodiment, the tea bar machine can automatically enter the manual calibration stage after power-on startup is completed. The current altitude information can be obtained in the first time. If the user does not input the current altitude information when the manual calibration stage is entered, the manual calibration stage can be entered again in other stages.

[0085] Specifically, after the initialization of the machine startup stage is completed, the tea bar machine can enter the manual calibration interface through the set display interface to remind the user to input the altitude information. At this time, the user can calibrate and confirm the predetermined boiling point temperature displayed by the tea bar machine according to the current altitude information, or input the altitude calibration information through the altitude selection after the machine is started. When the heating process is started, the determination stage does not need to be entered again, and the actual boiling point temperature after calibration can be directly used to set the heating control logic. Alternatively, when the user first starts the heating function, the manual calibration interface is automatically entered. At this time, the user can calibrate and confirm the altitude information through the key. After confirming that the information is correct, the program saves the current altitude information and continues to execute the heating process, and controls the heating logic according to the current altitude information and the actual water temperature.

[0086] Meanwhile, the user can manually enter the manual calibration stage by inputting preset content, for example, entering a combination of keys, inputting a specified character, and the like to enter the manual calibration stage and make setting adjustments. In this process, the actual boiling point temperature recognized by the tea bar machine or the manually input altitude information can also be modified. For example, if the user feels that the boiling is too intense, the user can appropriately reduce the boiling point value set in the tea bar machine. If the user expects the boiling to last longer or the boiling effect to be more obvious, the user can appropriately increase the boiling point value set in the tea bar machine. If the altitude information is manually input after the heating process is started, the altitude determination stage is not entered, and heating logic control is directly performed according to the set altitude information.

[0087] The application does not limit the way in which the user inputs the altitude information. The application can be provided with a digital panel, a virtual panel, or the like to enable the user to directly input the altitude information. Alternatively, the user can operate keys to select the altitude information in a stepwise manner. The specific type can be selected according to the actual situation.
