Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments of the present invention and the features of the embodiments can be combined with each other without conflict, and the formed technical solutions are within the scope of the present invention.
The invention provides an electric kettle, and fig. 1 is a logic block diagram of the electric kettle provided by the embodiment of the invention, as shown in fig. 1, the electric kettle 1 includes a key 11, a temperature sensor 12, a processor 13 and a heating element 14, and the key 11, the temperature sensor 12 and the heating element 14 are all electrically connected with the processor 13.
Wherein, the user can operate the electric kettle 1 by pressing the key 11, and the key 11 generates a heating operation instruction based on the user operation and sends the heating operation instruction to the processor 13.
The temperature sensor 12 is used to measure the temperature of the water inside the electric kettle 1 and to send the measured temperature of the water to the processor 13. Alternatively, the temperature sensor 12 may be, but is not limited to, a platinum resistance temperature sensor, a thermocouple temperature sensor, a thermistor temperature sensor, or the like.
The heating element 14 is used to heat the water in the electric kettle 1. Alternatively, the heating element 14 may be, but is not limited to, an electromagnetic heater, a resistive wire heater, or the like.
Taking the heating of the electric kettle in the prior art as an example, as shown in fig. 1, when a user inputs a heating operation command through a key 11, a processor 13 receives the heating operation command and controls a heating element 14 to operate, so as to heat water in the electric kettle 1, a temperature sensor 12 measures a current water temperature in the electric kettle 1 in real time, and when the current water temperature reaches a preset boiling point (for example, 100 ℃), the heating element 14 is controlled to be powered off to stop heating, so as to complete a water boiling operation.
Due to different air pressures in different altitude areas, the boiling points of water in different altitude areas are different, for example, the boiling point of water in a low altitude area may be 100 ℃, the boiling point of water in a high altitude area may be 80 ℃, while in the prior art, the preset boiling point is a fixed value, and when the same electric kettle in the prior art is applied to different altitude areas, the heating element of the electric kettle cannot be accurately powered off according to actual conditions. It can be understood that, if the preset boiling point of the electric kettle in the prior art is 100 ℃ in the low altitude area, when the electric kettle is used in the high altitude area, the boiling point of the high altitude area is 80 ℃, but the maximum value of the water temperature collected by the temperature sensor 12 is 80 ℃, so that the boiling point of the high altitude area is always 80 ℃ lower than the preset boiling point 100 ℃, and therefore, the heating element 14 cannot be powered off, and the heating state is always maintained, which may cause potential safety hazards such as dry water in the electric kettle. On the contrary, if the preset boiling point of the electric kettle in the prior art is 80 ℃ of the boiling point of the high altitude area, when the electric kettle is used in the low altitude area, since the boiling point of the low altitude area is 100 ℃ but the water temperature collected by the temperature sensor 12 is 80 ℃, the processor 13 controls the heating element 14 to be powered off and stop heating, the water in the electric kettle 1 does not actually reach the boiling point, so that more bacteria may remain in the water, and the health of the user may be harmed when the user drinks the water in the electric kettle.
In view of the above problems of the electric kettle in the prior art, the following embodiments of the present invention provide a heating control method for an electric kettle, which has the following core improvements: the preset boiling point set by the invention is a temperature value obtained after temperature compensation is carried out on the current boiling point.
It should be noted that the defects of the solutions in the above prior art are the results obtained after the inventor has made practice and careful study, therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present invention to the above problems should be the contribution of the inventor to the present invention in the course of the present invention. The following describes in detail a heating control method, a heating control system, a storage medium, a heating control device, and an electric kettle according to an embodiment of the present invention.
Example one
Fig. 2 is a schematic flow chart of a heating control method for an electric kettle according to an embodiment of the present invention, and it should be noted that the heating control method for an electric kettle according to an embodiment of the present invention is not limited by fig. 2 and the following specific sequence, and it should be understood that, in other embodiments, the sequence of some steps in the heating control method for an electric kettle according to an embodiment of the present invention may be interchanged according to actual needs, or some steps may be omitted or deleted. This process may be executed by the corresponding processor 13 in fig. 1, and the specific process referred to in fig. 2 will be described below, as shown in fig. 2, the method includes:
and step S1, when the heating element of the electric kettle works, acquiring the current water temperature of the water in the electric kettle.
And step S2, judging whether the current water temperature is greater than or equal to a preset boiling point, wherein the preset boiling point is a temperature value obtained by temperature compensation of the current boiling point.
If the current water temperature is greater than or equal to the preset boiling point, the process goes to step S3; if the current water temperature is not greater than or equal to the preset boiling point, that is, the current water temperature is less than the preset boiling point, the process proceeds to step S4.
And step S3, controlling the heating element to stop working.
For example, when the preset boiling point is 100 ℃, and the current water temperature is 100 ℃, the processor 13 controls the heating element 14 to stop working, so that potential safety hazards such as dry heating of the electric kettle and the like caused by continuous heating of water in the electric kettle are avoided.
And step S4, controlling the heating element to keep working.
When the current water temperature is detected to be 80 ℃, the current water temperature is 80 ℃ to be less than the preset boiling point of 100 ℃, the water in the electric kettle 1 does not reach 100 ℃, and the processor 13 controls the heating element 14 to keep working state, so that the heating element 14 continuously heats the water in the electric kettle 1.
The electric kettle heating control method that this embodiment provided, when the heating element during operation of electric kettle, obtain the current temperature of electric kettle water-logging, judge whether current temperature is more than or equal to and predetermine the boiling point, wherein predetermine the boiling point and be the temperature value that obtains after carrying out temperature compensation to current boiling point, current boiling point is the boiling point of current height above sea level department water, if current temperature is more than or equal to and predetermines the boiling point, control heating element stop work, through carrying out temperature compensation to current boiling point, the accuracy of the boiling point of predetermineeing of having guaranteed the setting, cut off the power supply according to predetermineeing the boiling point, make same electric kettle use also can accurately cut off the power supply in different height above sea level.
Example two
As shown in fig. 3, before step S2 of the first embodiment, the method further includes:
and step S5, when a reset instruction input by a user is received, acquiring the current boiling point of water in the electric kettle.
Alternatively, the user may input a reset instruction through the key 11.
And step S6, obtaining the compensation temperature according to the reference boiling point and the current boiling point.
The reference boiling point is the boiling point of water in the reference sea level area; the current boiling point is the boiling point of water in the current sea-level area where the electric kettle is located.
And step S7, performing temperature compensation on the current boiling point according to the current boiling point and the compensation temperature to obtain a preset boiling point.
Alternatively, the preset boiling point may be obtained by the formula (1-1):
T1=T2+T3 (1-1)
wherein, T1 is the preset boiling point, T2 is the current boiling point, and T3 is the compensation temperature.
It should be noted that, the step of obtaining the preset boiling point is not required before each time the electric kettle is used, when the user sends a change in the area where the electric kettle is used, the user inputs a reset instruction through the key 11, and the processor 13 executes the steps S5 to S7 to obtain the preset boiling point again after receiving the reset instruction.
According to the heating control method for the electric kettle, the obtained preset boiling point can more accurately reflect the boiling point of water at the current altitude by adopting temperature compensation on the current boiling point, so that the electric kettle can accurately control the power-off of the heating element of the electric kettle according to the preset boiling point.
EXAMPLE III
Fig. 4 is a schematic flowchart of the sub-step of step S5 in fig. 3, and as shown in fig. 4, step S5 in the second embodiment includes:
and a substep S51 of acquiring the water temperature in the electric kettle in real time.
The temperature sensor 12 acquires the temperature of water in the electric kettle in real time and sends the temperature to the processor 13.
And a sub-step S52 of determining the water temperature as the current boiling point when the water temperature at the first time is the same as the water temperature at a second time, which is after the first time and spaced apart by a preset time.
Since the water temperature remains constant even though the heating is continued after the water is heated to the boiling point, the processor 13 determines that the water temperature is the boiling point when the water temperature at the first time is the same as the water temperature at the second time.
It should be noted that, in order to ensure the accuracy of the current boiling point, the preset time interval between the first time and the second time may be a large value, such as 30 seconds, 1 minute, etc.
Example four
Since the water vapor environment in the electric kettle and the impact of water boiling are not conducive to directly measuring the temperature of water in the electric kettle, in this embodiment, the current temperature of water in the electric kettle is indirectly obtained by directly obtaining the current temperature at the bottom of the electric kettle, fig. 5 is a schematic flow chart of the sub-step of step S51 in fig. 4, as shown in step S51 in the third embodiment shown in fig. 5, the method includes:
and S511, acquiring the temperature of the bottom of the electric kettle collected by the temperature sensor of the electric kettle in real time.
And a substep S512 of obtaining the water temperature in the electric kettle according to the prestored corresponding relation between the temperature at the bottom of the electric kettle and the water temperature in the electric kettle and the temperature at the bottom of the electric kettle.
It can be understood that there is a corresponding relationship between the current temperature at the bottom of the electric kettle and the current water temperature inside the electric kettle, for example, the corresponding relationship may be a graph of the current temperature-the current water temperature, and the current water temperature inside the electric kettle may be obtained according to the current temperature at the bottom of the electric kettle and the corresponding relationship.
For example, the current temperature of the bottom of the electric kettle is 25 ℃, and according to the corresponding relation, the current water temperature in the electric kettle is 20 ℃; the current temperature of the bottom of the electric kettle is 98 ℃, and the current water temperature inside the electric kettle is 100 ℃ according to the corresponding relation.
EXAMPLE five
Fig. 6 is a schematic flowchart of the sub-step of step S6 in fig. 2, and as shown in fig. 6, step S6 in the second embodiment includes:
and a substep S61 of calculating a temperature difference between the reference boiling point and the current boiling point.
Alternatively, the temperature difference can be obtained by the formula (1-2):
△T=T4-T2 (1-2)
where Δ T is the temperature difference and T4 is the reference boiling point.
Optionally, the reference boiling point is 100 ℃, and when the current boiling point is 80 ℃, the temperature difference is 20 ℃; when the current boiling point is 90 ℃, the temperature difference is 10 ℃.
And a substep S62, obtaining a temperature coefficient corresponding to the temperature difference according to the pre-stored correspondence between the temperature difference and the temperature coefficient and the temperature difference.
Optionally, the corresponding relationship between the temperature difference and the temperature coefficient may be a mapping table, as shown in table 1:
TABLE 1
△T | 20℃ | 10℃ |
k | -0.2 | -0.5 |
Where k in table 1 is a temperature coefficient.
And a substep S63, obtaining a compensation temperature according to the temperature difference and the temperature coefficient.
Alternatively, the compensated temperature may be obtained by the formula (1-3):
T3=k*△T (1-3)
wherein, T3 is the compensation temperature.
Since the residual heat of the heating element 14 can continue to heat the water inside the electric kettle 1 to the current boiling point when it is just stopped, the preset boiling point set for power-off is lower than the current boiling point, it being understood that the compensation temperature is actually the temperature heated by the residual heat of the heating element 14. If the current boiling point is larger, the heating element 14 will have more heat and therefore will provide a larger compensation temperature when it is just out of service, whereas if the current boiling point is smaller, the heating element 14 will have less heat and therefore will provide a smaller compensation temperature when it is just out of service.
In connection with the above example, the reference boiling point is 100 deg.C, and when the current boiling point is 80 deg.C, the temperature difference △ T is obtained by the formula (1-2)1At 20 ℃, the temperature coefficient k was obtained from the mapping in Table 11And-0.2, the offset temperature T31 was-4 ℃ by the formula (1-3), and the preset boiling point T11 was 76 ℃ by the formula (1-1). Thus, at this altitude, when the electric kettle is heated to 76 ℃, the processor 13 controls the heating element 14 to be powered off, and the water in the electric kettle is heated to the current boiling point of 80 ℃ by the preheating of the heating element 14.
Similarly, when the current boiling point is 90 ℃, the temperature difference △ T is obtained by the formula (1-2)2At 10 ℃, the temperature coefficient k was obtained from the mapping in Table 12And-0.5, the offset temperature T32 was-5 ℃ by the formula (1-3), and the preset boiling point T12 was 85 ℃ by the formula (1-1). Therefore, at this altitude, when the electric kettle is heated to 85 ℃, the processor 13 controls the heating element 14 to be powered off, and the water in the electric kettle is heated to the current boiling point of 90 ℃ by utilizing the preheating of the heating element 14.
Compared with the prior art, one or more embodiments in the above scheme can have the following advantages or beneficial effects:
(1) when a heating element of the electric kettle works, the current water temperature of water in the electric kettle is obtained, whether the current water temperature is larger than or equal to a preset boiling point or not is judged, wherein the preset boiling point is a temperature value obtained after temperature compensation is carried out on the current boiling point, the current boiling point is the boiling point of water at the current altitude, if the current water temperature is larger than or equal to the preset boiling point, the heating element is controlled to stop working, the accuracy of the set preset boiling point is ensured by carrying out temperature compensation on the current boiling point, and power is cut off according to the preset boiling point, so that the same electric kettle can be accurately powered off when applied to different altitude areas, the potential safety hazards of dry heating of the electric kettle and the like caused by continuous heating of the water in the electric kettle are avoided, or the heating is stopped when the water in;
(2) the temperature sensor is used for directly measuring the temperature at the bottom of the electric kettle to indirectly obtain the water temperature in the electric kettle, so that the damage of the steam environment in the electric kettle and the impact of water boiling on the temperature sensor can be avoided, and the accuracy of the water temperature test in the electric kettle is ensured;
(3) the electric kettle has the advantages that the preset boiling point is obtained by compensating the current boiling point, the water in the electric kettle is boiled by preheating the heating element, electric energy is saved, and dry heating of the electric kettle caused by less water in the electric kettle is prevented.
