Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An electric cooker and an anti-overflow control method and apparatus thereof according to embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of an overflow preventing control method of an electric cooker according to an embodiment of the present invention.
As shown in fig. 1, the method for controlling an anti-overflow of an electric cooking device according to an embodiment of the present invention includes the following steps:
and S1, controlling the electric cooker to enter a first stage when the electric cooker starts to cook, and controlling the electric cooker to heat at a first heating power in the first stage.
Wherein the first heating power may be a maximum heating power of the electric cooker in the current cooking mode.
And S2, acquiring the temperature in the electric cooking device, judging that the electric cooking device enters a second stage according to the temperature in the electric cooking device, and controlling the electric cooking device to heat with second heating power, wherein the second heating power is smaller than the first heating power.
In one embodiment of the present invention, the bottom temperature and the upper temperature of the electric cooker may be detected by a bottom temperature sensor located at the bottom of the electric cooker and an upper temperature sensor located at the upper cover of the electric cooker, respectively, and the temperature inside the electric cooker may be obtained based on the bottom temperature and the upper temperature of the electric cooker. When both the bottom temperature and the upper temperature reach the first temperature threshold, it may be determined that the electric cooker enters the second stage. Wherein, in the second stage, the temperature of the food in the electric cooker may gradually reach the boiling point, and the temperature is not increased any more. After the electric cooker enters the second stage, the electric cooker can be controlled to heat at the second heating power.
In one embodiment of the present invention, the first temperature threshold may be 75-85 ℃, that is, when both the bottom temperature and the upper temperature of the electric cooking device reach or exceed 75-85 ℃, the heating power of the electric cooking device may be reduced.
And S3, acquiring the balance temperature of the electric cooker after entering the second stage, judging the altitude of the current environment of the electric cooker according to the balance temperature to adjust the heating power of the electric cooker, and controlling the electric cooker to heat with the adjusted heating power to prevent the overflow phenomenon of the electric cooker.
In one embodiment of the present invention, the first timer and the second timer may be controlled to count time respectively when the electric cooker is controlled to heat at the second heating power. When the timing time of the first timer reaches a first preset time and the timing time of the second timer does not reach a second preset time, acquiring and comparing the plurality of upper temperature to take the maximum temperature in the plurality of upper temperature as a balance temperature, wherein the second preset time is longer than the first preset time. During the subsequent acquisition of the upper temperature, if the subsequent upper temperature is greater than all previous upper temperatures, the equilibrium temperature is refreshed with the maximum upper temperature. In one embodiment of the invention, the equilibrium temperature is in the range of 80 ℃ to 100 ℃ and is discarded when the upper temperature is outside this range.
After the balance temperature of the electric cooker after entering the second stage is obtained, the balance temperature can be judged. If the balance temperature is greater than or equal to the first preset temperature, adjusting the heating power of the electric cooker to a third heating power, wherein the third heating power is less than the second heating power; if the balance temperature is greater than or equal to a second preset temperature and less than the first preset temperature, adjusting the heating power of the electric cooker to a fourth heating power, wherein the second preset temperature is less than the first preset temperature, and the fourth heating power is less than the third heating power; and if the balance temperature is lower than the second preset temperature, adjusting the heating power of the electric cooker to be a fifth heating power, wherein the fifth heating power is lower than the fourth heating power.
It should be noted that the above embodiment uses the first preset temperature and the second preset temperature as the determination criteria for adjusting the heating power, which is only an embodiment of the present invention, and should not be a limitation on the manner of adjusting the heating power of the electric cooker according to the equilibrium temperature according to the present invention. In other embodiments of the present invention, another preset temperature, three preset temperatures or more preset temperatures may also be used as the determination criterion for adjusting the heating power.
In general, after the equilibrium temperature is obtained, the heating power of the electric cooker may be further reduced, and the lower the equilibrium temperature, the smaller the heating power of the electric cooker. Therefore, when the altitude is higher, the boiling point is lower, namely the equilibrium temperature is lower, and the electric cooker is heated by correspondingly lower heating power, so that the overflow phenomenon of the electric cooker can be effectively prevented.
In an embodiment of the present invention, after the time counted by the second timer reaches the second preset time, the electric cooker may be controlled to enter the third stage, and in the third stage, the electric cooker may be heated with the sixth heating power, and whether to control the electric cooker to stop heating may be determined according to the equilibrium temperature and the upper temperature. The sixth heating power may be a relatively low heating power, for example, may be slightly greater than 1W, which may effectively prevent the temperature in the electric cooking device from further increasing due to the electric cooking device being heated for more than the second preset time with the third to fifth heating powers.
It should be understood that if the temperature in the electric cooker is already high when the counted time of the second timer reaches the second preset time, the electric cooker may be directly controlled to stop heating. Specifically, the equilibrium temperature and the upper temperature can be judged, and if the equilibrium temperature is greater than or equal to a first preset temperature and the upper temperature is greater than a third preset temperature, the electric cooker is controlled to stop heating, wherein the third preset temperature is greater than the first preset temperature; if the balance temperature is greater than or equal to a second preset temperature and less than a first preset temperature, and the upper temperature is greater than the difference between the balance temperature and the first preset difference, controlling the electric cooker to stop heating; and controlling the electric cooker to stop heating if the equilibrium temperature is less than the second preset temperature and the upper temperature is greater than the difference between the equilibrium temperature and the second preset difference.
In addition, when heating is performed with the sixth heating power, or after the electric cooker is controlled to stop heating, whether the cooking time reaches the preset total cooking time can be judged. If the cooking time reaches the preset total cooking time, namely the current cooking mode is finished, the cooking can be finished; if the cooking time does not reach the preset total cooking time, the heating process can be continued when the sixth heating power is used for heating, after the electric cooker stops heating, the electric cooker can be controlled again to heat with the sixth heating power within a short time, and whether the electric cooker is controlled to stop heating is judged again according to the balance temperature and the upper temperature. That is, when the cooking time does not reach the preset total cooking time, the control process of the third stage may be performed in a loop until the cooking is finished. It should be appreciated that the electric cooker can be maintained within the proper temperature range by controlling the electric cooker to heat at the sixth heating power in the third stage and controlling the electric cooker to stop heating when the equilibrium temperature and the upper temperature satisfy a certain condition.
According to the anti-overflow control method of the electric cooker, the electric cooker is heated with the first heating power in the first stage of starting cooking, the heating power can be reduced primarily after the electric cooker enters the second stage, after the balance temperature of the electric cooker after entering the second stage is obtained, the altitude of the current environment of the electric cooker is judged according to the balance temperature so as to adjust the heating power of the electric cooker, and the electric cooker is controlled to be heated with the adjusted heating power, so that the overflow phenomenon of the electric cooker can be effectively prevented.

s201, initializing a first and a second timer.

S207, the maximum value of the upper temperature in the second stage is obtained through comparison and is recorded as the equilibrium temperature Tad. If the upper temperature is higher than all the previous upper temperatures, then the Tad is refreshed at the maximum upper temperature. The value range of Tad is 80-100 deg.C, and when the upper temperature collected in said stage is out of said value range, all the upper temperatures are discarded.
S208, judging whether the Tad is less than 95 ℃. If so, go to step S209; if not, step S210 is performed.
S209, adjusting the heating power to P5.
S210, judging whether the Tad is less than 97 ℃. If yes, go to step S211; if not, step S212 is performed.
And S211, adjusting the heating power to P4.
S212, adjusting the heating power to P3. Wherein, P2 is more than P3 is more than P4 is more than P5. After adjusting the heating power, the process may return to step S204, and steps S204 to S212 may be repeatedly performed until the third stage is entered.
The third stage may include the following steps:
s213, judging whether the Tad fails to be acquired. If yes, go to step S214 first, then go to step S215; if not, step S215 is performed directly.
S214, Tad equal 100 ℃. That is, when the acquisition of Tad fails, the value of Tad can be directly assigned to 100 ℃.
S215, adjusting the heating power to P6. P6 may be greater than 1W.
S216, detecting the upper temperature TOP _ tep in real time.
S217, judging whether the Tad is less than 95 ℃. If yes, go to step S218; if not, step S220 is performed.
S218, whether TOP _ tep is larger than Tad-2 is judged. If so, go to step S219; if not, the process returns directly to step S215.
And S219, stopping heating. If Tad is less than 95 deg.C, and TOP _ tep is greater than Tad-2, it can be judged that the altitude of the environment where the electric cooker is currently located is more than 1500 meters.
S220, judging whether the Tad is less than 97 ℃. If yes, go to step S221; if not, step S223 is performed.
S221, judging whether TOP _ tep is larger than Tad-1. If yes, go to step S222; if not, the process returns directly to step S215.
S222, stopping heating. If Tad is greater than or equal to 95 ℃ and less than 97 ℃ and TOP _ tep is greater than Tad-1, the altitude of the environment where the electric cooker is currently located can be judged to be between 1000 and 1500 meters.
S223, judging whether Tad is more than or equal to 97 ℃. If yes, go to step S224; if not, the process returns directly to step S215.
S224, judge whether TOP _ tep is greater than 98 ℃. If so, go to step S225; if not, the process returns directly to step S215.
And S225, stopping heating. If Tad is greater than or equal to 97 ℃ and TOP _ tep is greater than 98 ℃, the altitude of the environment where the electric cooker is currently located can be judged to be between 0 and 1000 meters. After the heating is stopped, it may return to step S215 and repeatedly perform steps S215 to S225 until the cooking time of the electric cooker reaches the total cooking time preset in the current cooking mode.

After the electric cooker enters the second stage, the control module 30 may control the heating module 20 to heat at the second heating power.
In one embodiment of the present invention, the first temperature threshold may be 75-85 ℃, that is, the heating power of the heating module 20 may be reduced when both the bottom temperature and the upper temperature of the electric cooker reach or exceed 75-85 ℃.
In an embodiment of the present invention, the anti-overflow control device of the electric cooker may further include a first timer and a second timer, the control module 30 is configured to control the first timer and the second timer to time respectively when the electric cooker is controlled to heat at the second heating power, and when the timing time of the first timer reaches a first preset time and the timing time of the second timer does not reach a second preset time, the obtaining module 10 collects a plurality of upper temperatures and compares the upper temperatures to use a maximum temperature of the plurality of upper temperatures as a balance temperature, where the second preset time is greater than the first preset time. During the subsequent acquisition of the upper temperature, if the subsequent upper temperature is greater than all previous upper temperatures, the equilibrium temperature is refreshed with the maximum upper temperature.
