Detailed Description
The water boiling method embodiment of the water boiling device comprises the following steps:
the water boiling method of the water boiling device in the embodiment is an application program applied to the water boiling device and is used for controlling the water boiling device to boil water. Preferably, the water boiling device is an electric heating kettle.
As shown in fig. 1, in the present embodiment, when the water boiling method of the water boiling device is in operation, step S1 is first executed to heat water to a predetermined starting temperature. Wherein the predetermined starting temperature is preset according to experimental data, and preferably, the predetermined starting temperature is 40 ℃. In order to avoid frequent determination, the determination of the amplitude range of the current operating voltage is therefore carried out by now heating the water temperature to a predetermined starting temperature. In this embodiment, in order to facilitate the water temperature to quickly reach a required temperature value, the step of heating the water to a predetermined initial temperature includes: heating to a predetermined starting temperature at a rated power.
When it is determined that the temperature of the water in the water boiler is the predetermined starting temperature, step S2 is executed to heat at the preset power for a first preset time. The first preset time and the preset power are preset according to experimental data, preferably, the first preset time is 200 seconds, and the preset power is rated power. In order to determine the current heating condition of the water boiling device, the temperature reached after the water boiling device is heated for a period of time needs to be compared with the reference temperature, so that the water boiling device needs to be heated for a first preset time at preset power.
After heating for the first preset time period with the preset power, executing step S3, obtaining the first water temperature after heating for the first preset time period with the preset power, and determining the current heating condition according to the difference between the first water temperature and the first preset temperature. Wherein the first preset temperature is preset according to experimental data, and preferably, the first preset temperature is 70 ℃. The current heating working condition can be determined through the difference value between the first water temperature and the first preset temperature. The current heating working condition comprises the amplitude range of the current working voltage, the current water boiling amount, the current altitude and the like, and the factors are factors influencing the water boiling speed. In order to control the water boiling process of the water boiling device under different heating working conditions, the working conditions such as the amplitude range of the current working voltage need to be determined so as to facilitate the subsequent heating control.
The following description takes the amplitude range of the current operating voltage as the current operating condition as an example.
In this embodiment, determining the current heating condition according to the difference between the first water temperature and the first preset temperature includes: when the difference value is larger than a first threshold value, determining that the amplitude range of the current working voltage is in a high-voltage range; when the difference value is smaller than or equal to the first threshold value and larger than or equal to the second threshold value, determining that the amplitude range of the current working voltage is in a normal voltage range; and when the difference value is smaller than a second threshold value, determining that the amplitude range of the current working voltage is in a low-voltage range. In this embodiment, the first threshold and the second threshold may be preset according to experimental data, and preferably, the first threshold is 5 ℃ and the second threshold is-5 ℃.
After the current heating condition is determined, step S4 is executed, and the heating power is controlled in a segmented manner according to the current heating condition until the preset heating stop condition is satisfied, and then the heating is stopped. According to the current heating working condition, the heating power is controlled in a segmented mode, so that the water boiling device can accurately control the heating power in a segmented mode under the current heating working condition, and the water boiling process can be accurately controlled according to different heating working conditions.
In this embodiment, the amplitude range of the current working voltage is used as the current heating condition, and the higher the amplitude range of the current working voltage is, the lower the heating power is.
Referring to fig. 2, when the heating power is controlled in a segmented manner according to the current heating condition, step S21 is executed first, and a first heating stage is performed to heat with a first preset heating power, so that the water temperature reaches a first target temperature. When the heating power is controlled in a segmented mode, a first heating stage is firstly carried out, and the water temperature reaches a first target temperature. In this embodiment, when the amplitude range of the current working voltage is in the high-voltage range, the first preset heating power is 70% of rated power, and when the amplitude range of the current working voltage is in the normal voltage range, the first preset heating power is 80% of rated power; when the amplitude range of the current working voltage is in the low-voltage range, the first preset heating power is 90% of rated power. The first target temperature is preset according to experimental data, the value range of the first target temperature is 82-90 ℃, and preferably, the first target temperature is 88 ℃.
After the water temperature reaches the first target temperature, step S22 is executed, and the heating stage is entered to heat with a second preset heating power to make the water temperature reach the second target temperature. In the embodiment, when the amplitude range of the current working voltage is in a high-voltage range, the second preset heating power is 60% of rated power, and the second target temperature is 93 ℃; when the amplitude range of the current working voltage is in the normal voltage range, the second preset heating power is 65% of rated power, and the second target temperature is 95 ℃; when the amplitude range of the current working voltage is in the low-voltage range, the second preset heating power is 70% of rated power, and the second target temperature is 97 ℃.
After the water temperature reaches the second target temperature, step S23 is executed to enter a third heating stage, and heating is performed at a third preset heating power. In the embodiment, when the amplitude range of the current working voltage is in a high-voltage range, the third preset heating power is 50% of rated power; when the amplitude range of the current working voltage is in the normal voltage range, the third preset heating power is 55% of rated power; when the amplitude range of the current working voltage is in the low-voltage range, the third preset heating power is 60% of rated power. When entering the third heating stage, the water temperature is already close to the boiling point, and moderate boiling of the water is realized by heating with a third preset heating power. In order to avoid the problems of abnormal display of the water boiling end point temperature and poor user experience caused by the abnormal display, temperature compensation can be carried out in the period of time, the temperature display of the last stage of water boiling is processed, and the temperature is just displayed as the designated temperature when the water boiling is finished.
After heating at the third preset heating power, step S24 is executed to determine whether the heating stop condition is satisfied. In order to avoid the water temperature boiling too long during heating, it is necessary to determine whether to stop the heating condition.
In the present embodiment, satisfying the stop heating condition includes: the heating time length with the third preset heating power reaches the second preset time length. The second preset time length is correspondingly set according to the amplitude range of the current working voltage, and the second preset time length is reduced along with the increase of the amplitude range, in the embodiment, when the amplitude range of the current working voltage is in a high-voltage range, the second preset time length is 20 seconds; when the amplitude range of the current working voltage is in the normal voltage range, the second preset time is 30 seconds; when the amplitude range of the current working voltage is in the low-voltage range, the second preset time is 40 seconds.
In this embodiment, satisfying the stop heating condition further includes: the time length of entering the second heating stage and the time length of entering the third heating stage reach a third preset time length. In the embodiment, when the amplitude range of the current working voltage is in the high-voltage range, the third preset time length is 100 seconds; when the amplitude range of the current working voltage is in the normal voltage range, the third preset time is 120 seconds; when the amplitude range of the current working voltage is in the low-voltage range, the third preset time period is 140 seconds.
And when the heating condition stopping is judged, if the third preset time length is reached and the second preset time length is not reached, taking the third preset time length as the judgment of the heating condition stopping.
If it is determined that the heating stop condition is not met, the step S23 is continuously executed to heat at a third preset heating power. If it is confirmed that the heating stop condition is reached, step S25 is executed to stop heating. If the heating stop condition is confirmed, the current water temperature reaches the boiling point, so the heating is stopped and the power supply is cut off.
