All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In the correlation technique, the health preserving kettle adopts simpler hardware system, consequently can't distinguish the voltage condition of health preserving kettle, the heating process of water can be influenced to the service voltage of health preserving kettle, the voltage of different areas or different service interval can be different, if do not distinguish the voltage condition, low-voltage condition temperature can not reach the heat preservation temperature that the user set for when probably leading to the heat preservation procedure to start, or the high-voltage condition heats the too violent temperature and surpasss the heat preservation temperature that the user set for, consequently, be difficult to carry out effectual control to the heat preservation procedure, cause the problem such as user experience is relatively poor or the electric energy is extravagant.
In order to solve the above technical problem, an embodiment of the present application provides a heating control method for improving a heat preservation effect, as shown in fig. 1, the method includes the following steps:
In application, the health preserving pot enters a self-checking stage after being powered on, the heating component does not work within the initial designated time, and then the health preserving pot enters an initial heating stage, so that the initial heating stage in the embodiment refers to the first heating stage after the health preserving pot is powered on.
It will be appreciated that the rate of temperature rise is inversely proportional to the heating time and directly proportional to the temperature rise of the liquid during heating. The procedure for obtaining the rate of temperature rise is described below for the heating time and the temperature, respectively, at which the liquid is raised during heating:
first, the set heating time is fixed, and the rate of temperature rise is obtained based on the temperature at which the liquid rises during heating, specifically:
detecting the initial temperature of the liquid; predicting a first time consumed for heating the liquid from the initial temperature to a target temperature, wherein the target temperature is a preset heat preservation temperature; detecting and obtaining the current temperature of the liquid after the liquid is heated from the initial temperature for a second time, wherein the second time is less than the first time; a temperature rise rate is determined based on the second duration, the initial temperature, and the current temperature.
In the application, the initial temperature of liquid is the temperature when liquid adds the health preserving kettle, and the health preserving kettle has not controlled the heating element and heats liquid this moment.
In order to avoid the control logic being too complex and to minimize overheating of the liquid, the second period is set to be half the first period in this embodiment. Through heating liquid according to half of first time length, the temperature surplus is sufficient, not only can reduce the phenomenon of superheating to make things convenient for follow-up heating process's adjustment, realize the accurate control of heat preservation process.
Wherein the formula for determining the rate of temperature rise is as follows:
wherein V is the rate of temperature rise, T2Is the current temperature, T1T is the second time period for the initial temperature.
Secondly, the temperature rise of the liquid in the heating process is set to be fixed, and the temperature rise rate is obtained based on the heating time, specifically:
detecting the initial temperature of the liquid; determining the midpoint temperature of the initial temperature and the target temperature, wherein the target temperature is a preset heat preservation temperature; determining a heating time period consumed for heating the liquid from the initial temperature to the midpoint temperature; the rate of temperature rise is determined based on the length of heating time, the initial temperature, and the midpoint temperature.
Wherein V is the rate of temperature rise, T2Is the midpoint temperature, T1The initial temperature, t is the heating time.
And 102, determining the voltage condition of the service voltage of the health preserving kettle based on the temperature rise rate.
In application, in order to reduce the complexity of the control program, when the temperature difference between the target temperature and the initial temperature is smaller than the temperature threshold, the voltage identification is not needed, so the temperature difference between the target temperature and the initial temperature can be determined before the voltage condition of the service voltage of the health preserving kettle is determined based on the temperature rise rate, and when the temperature difference is not smaller than the temperature threshold, the voltage condition of the service voltage of the health preserving kettle is determined based on the temperature rise rate.
The temperature threshold here can be set manually based on experience, for example, setting the temperature threshold at 15 ℃.
When the temperature difference between the target temperature and the initial temperature is smaller than the temperature threshold, the health preserving kettle can be set to heat the liquid with smaller power in the initial heating stage, for example, the liquid with 30% of rated power, and a minimum temperature difference limit value is set, and the heating is stopped when the temperature difference between the temperature of the liquid and the target temperature is smaller than the minimum temperature difference limit value. The minimum temperature difference limit can be set empirically, for example, by setting the minimum temperature difference limit to 3 ℃.
And when the temperature difference between the target temperature and the initial temperature is not less than the temperature threshold, the health preserving kettle is set to heat the liquid at the rated power in the initial heating stage.
In this embodiment, the voltage conditions of the service voltage of the health preserving kettle include a first voltage condition, a second voltage condition and a third voltage condition. Wherein the voltage used in the first voltage condition is greater than the voltage used in the second voltage condition, and the voltage used in the second voltage condition is greater than the voltage used in the third voltage condition. In application, the used voltage in the first voltage condition is in a voltage interval of [231V, 245V ]; the used voltage in the second voltage condition is in a voltage interval of [211V, 230V ]; the voltage used in the third voltage condition is in the voltage interval [187V, 210V ].
In the embodiment, when the voltage condition of the service voltage of the health preserving kettle is determined based on the temperature rise rate, and when the temperature rise rate is greater than the first rate, the voltage condition is determined to be a high-voltage condition; when the temperature rise rate is not greater than the first rate and not less than the second rate, determining that the voltage condition is a commercial voltage condition; when the temperature rise rate is less than the second rate, the voltage condition is determined to be a low voltage condition.
Wherein the first rate is greater than the second rate, and the first rate and the second rate can be set manually based on experience.
In application, when the liquid is heated for half of the first time length, the current temperature obtained by detection has a linear relation with the temperature rise rate, so that the voltage condition of the service voltage of the health preserving kettle can be determined by replacing the temperature rise rate with the current temperature.
Specifically, a first temperature difference between the current temperature and the initial temperature and a second temperature difference between the target temperature and the initial temperature are determined; determining a product value of a preset multiple and the first temperature difference; determining a ratio of the product value to the second temperature difference; when the ratio is larger than a first ratio threshold, determining the voltage condition of the service voltage of the health preserving pot as a high voltage condition; when the ratio is not greater than the first ratio threshold and not less than the second ratio threshold, determining the voltage condition of the service voltage of the health preserving pot as a commercial voltage condition; and when the ratio is smaller than a second ratio threshold value, determining that the voltage condition of the service voltage of the health preserving kettle is a low-voltage condition.
Wherein the second ratio threshold is less than the first ratio threshold.
In application, the first ratio threshold value and the second ratio threshold value are set based on experience artificially. If the first ratio threshold is set to 1.1, the second ratio threshold is set to 0.9.
103, determining heating parameters of each subsequent heating stage and temperature conditions for the health preserving kettle to exit from heating based on the voltage conditions of the used voltage.
In this embodiment, the heating parameters of each subsequent heating stage include heating power, and when the health preserving kettle is in different heating stages, the heating power is different. In application, a mapping relation between the voltage condition and the heating parameter of each heating stage can be established in advance, so that the heating parameter of each subsequent heating stage is determined based on the mapping relation.
Of course, the heating power of the first subsequent heating stage and the proportional relationship of the heating powers of the different subsequent heating stages under different voltage conditions may also be preset, so that the heating parameters of each heating stage are obtained based on the proportional relationship of the heating power of the first subsequent heating stage and the heating powers of the different subsequent heating stages.
Wherein the heating power of the first subsequent heating stage under the first voltage condition is less than the heating power of the first subsequent heating stage under the second voltage condition; the heating power of the first subsequent heating stage under the second voltage condition is less than the heating power of the first subsequent heating stage under the third voltage condition.
In application, the heating power of the first subsequent heating stage under different voltage conditions can be manually set based on experience. For example, the heating power of the first subsequent heating stage under the first voltage condition is set to be 30% -40% of the rated power; setting the heating power of the first subsequent heating stage to be 40-50% of rated power under the second voltage condition; and setting the heating power of the first subsequent heating stage under the third voltage condition to be 50-60% of the rated power.
In application, each subsequent heating stage after the first subsequent heating stage can be set to be reduced proportionally. For example, the rated power is set to be decreased by 5%, it should be understood that 5% is only an example, and this embodiment is not limited thereto.
In this case, the following is performed for any one of the subsequent heating stages:
determining the initial temperature of any subsequent heating stage based on the current temperature, wherein when any subsequent heating stage is a heating stage adjacent to the just finished heating stage, the initial temperature of any subsequent heating stage is the current temperature; determining a third time period for heating in any subsequent heating stage based on the initial temperature and the target temperature in any subsequent heating stage; determining a heating power for any subsequent heating phase based on the voltage condition using the voltage; and determining the third time length and the heating power as the heating parameters of any subsequent heating stage.
When the just-finished heating stage is the initial heating stage, any subsequent heating stage is the first subsequent heating stage.
In this embodiment, the third time period is the actual heating time period in any subsequent heating stage. Predicting a fourth time period consumed for heating the liquid from the initial temperature to the target temperature in any subsequent heating stage, specifically when the third time period is determined; determining the time length proportion of the second time length to the first time length; the third time period is determined based on the time period proportion and the fourth time period.
The ratio of the second duration to the first duration is specifically the ratio of the second duration to the first duration.
And determining the third time length based on the time length proportion and the fourth time length, determining the product of the time length proportion and the fourth time length, and determining the product as the third time length.
In this embodiment, the heating power of any subsequent heating stage is determined in a proportional decreasing manner. Specifically, when any subsequent heating stage is a heating stage adjacent to the initial heating stage, determining that the heating power corresponding to the first voltage condition is a first power, the heating power corresponding to the second voltage condition is a second power, and the power corresponding to the third voltage condition is a third power, wherein the first power is smaller than the second power, and the second power is smaller than the third power; and when any subsequent heating stage is not the heating stage adjacent to the initial heating stage, acquiring the heating power of the previous heating stage adjacent to any subsequent heating stage, and reducing the heating power of the previous heating stage according to a preset proportion to obtain the heating parameters of any subsequent heating stage.
When any subsequent heating stage is a heating stage adjacent to the initial heating stage, the subsequent heating stage is actually the first heating stage, so that the first power, the second power and the third power are the heating powers of the first subsequent heating stage, and therefore, the specific setting can be manually set to 30% -40% of the rated power, 40% -50% of the rated power and 50% -60% of the rated power on the basis of experience.
In application, the preset ratio may be set manually based on experience, for example, the preset ratio is set to 5%, it should be understood that 5% is only an example, and this embodiment is not particularly limited thereto.
In this embodiment, when the health preserving kettle exits from heating, the temperature of the liquid in the health preserving kettle differs from the target temperature by a preset temperature, and the preset temperatures set under different voltage conditions are different, that is, the temperature conditions at which the health preserving kettle exits from heating under different voltage conditions are different.
In application, the preset temperature can be set manually based on experience, for example, the preset temperature is set to be 6 ℃ under the first voltage condition; setting the preset temperature to be 4 ℃ under a second voltage condition; under the third voltage condition, the preset temperature was set to 2 ℃.
And step 104, heating the health preserving kettle according to the heating parameters until the temperature of the liquid meets the temperature condition.
According to the technical scheme provided by the embodiment of the application, the temperature rise rate of the liquid in the health preserving kettle in the initial heating stage is obtained; determining the voltage condition of the service voltage of the health preserving kettle based on the temperature rise rate; determining heating parameters of each subsequent heating stage and temperature conditions for the health preserving kettle to exit from heating based on the voltage conditions of the used voltage; and heating the health preserving kettle according to the heating parameters until the temperature of the liquid meets the temperature condition. The voltage condition of the service voltage of the health preserving kettle can be determined, and the heating parameters are determined based on the voltage condition, so that the problem that the water temperature after the heating stage is finished cannot reach the heat preservation temperature set by a user due to the low voltage condition or the water temperature exceeds the heat preservation temperature set by the user due to the fact that the water temperature is heated too hard under the high voltage condition can be avoided.
