For example, if a user washes or cuts dishes during a hot pot or hot oil process, it is easy to cause the pot to dry or the oil temperature to overheat, there is a risk of fire, and the cooking apparatus may be damaged.

According to the temperature change judging method and device, temperature change is judged according to the resonant frequency or the resonant period, so that heating power of the electromagnetic heating device is automatically controlled, temperature is quickly and effectively adjusted, dry heating phenomenon caused by overhigh temperature is avoided, or the phenomenon that the cooking effect is not ideal due to low temperature is avoided.
The control method of the cooking apparatus according to the present invention may further have the following technical features:
in the above technical solution, the step of controlling the heating power of the electromagnetic heating device according to the resonance period or the resonance frequency specifically includes: based on the increase of the resonance period, the change rate of the resonance period is larger than the first period change rate threshold value, and the heating power of the electromagnetic heating device is reduced; or reducing the heating power of the electromagnetic heating device based on the fact that the resonant frequency is reduced and the absolute value of the change rate of the resonant frequency is larger than the first frequency change rate threshold value.

For example, in the process of heating the pot, along with the temperature rise, the resonance period is in an increasing trend, the resonance frequency is in a decreasing trend, and when the change curve of the resonance period or the change curve of the resonance frequency reaches a certain slope, the heating power is automatically reduced from the initial power, so that the damage of cooking equipment caused by dry burning is avoided.

The duration of the decrease of the resonance period or the duration of the increase of the resonance frequency is smaller than the first time threshold, and the first time threshold is larger than 3s, which is equivalent to the gradual decrease of the resonance period or the gradual increase of the resonance frequency.

As shown in fig. 8, the method includes:
step 802, storing an initial heating power P, storing resonance period data, and calculating a slope.
Step 804, determining whether the resonance period is in an increasing trend and accords with the change rule of the hot pot, if yes, entering step 806, otherwise returning to step 802.
At step 806, the heating power is reduced from P to P1.
Steps 804 and 806 are a hot pot process, as shown in fig. 9, as the temperature increases, the resonance period of the IGBT of the electromagnetic heating device increases (for example, increases with a slope of Δ0), and when it is detected that the resonance period conforms to the hot pot process rule, that is, reaches a certain slope of Δ1, the initial heating power P is automatically reduced to P1.

Steps 808 through 814 are hot oil processes (including oil drain), and as shown in fig. 9, when the resonance period is detected to be increased (for example, increased with a slope of Δ2) after the momentary decrease, it is determined that the oil drain period is suddenly changed, and the heating power is increased back to the initial heating power P. When the slope of the resonance period reaches a certain slope delta 3, the method accords with the hot oil rule, and the fact that the temperature is too high is judged, and the heating power is reduced to P2 at the moment.
Step 816, determining whether the resonance period accords with the dish placing rule, if yes, entering step 818, otherwise returning to step 814.
At step 818, the heating power is increased to P.
Steps 816 and 818 are the vegetable discharging process, and as shown in fig. 9, when the resonance period is detected to be declined by Δ4 and the declining time period is longer than T1, the vegetable discharging process is determined, and the heating power is raised back to the initial heating power P.
Wherein, delta1 is more than or equal to Delta0, delta3 is more than or equal to Delta2, T1 is more than or equal to 3s, and P is more than or equal to P1 and P is more than or equal to P2.
It should be noted that, as shown in fig. 9, when the balance state is maintained after the resonance period is detected to suddenly increase or decrease, it is determined that the pan moving process is not performed with power adjustment. When there is a manual adjustment, a manually adjusted power mode is selected.
In a specific embodiment, the delay time 10s after starting operation stores resonance period data [ T1, T2, T3, T4, T5] for 5 seconds, and the resonance period slope is calculated every second, with 5 seconds as a unit time. If the resonance period is in an increasing trend, the slope Δ= t5-T1, and if the resonance period is in a decreasing trend, the slope Δ= t1-T5.
If the slope delta is more than or equal to 2 and the duration time T is more than or equal to 6s, the heating power is reduced to P less than or equal to 800W; if the resonance period suddenly decreases and then has an increasing trend, the slope delta is more than or equal to 2, and the duration time T is more than or equal to 5s, the heating power is reduced to P less than or equal to 700W; if the slope period is in a descending trend, the slope delta is more than or equal to 2 and the duration time T is more than or equal to 5s, the vegetable is judged to be put, and the heating power is increased to P more than or equal to 1500W.
The embodiment judges the stages of heating pot, hot oil, vegetable placement and the like through the slope of the resonance period change, and intelligently adjusts the firepower. When the temperature of the hot pot is judged to be too high, the power is automatically reduced, when the oil is discharged, the power is automatically reduced, and when the oil temperature is too high, the firepower is automatically increased.
The present embodiment is not limited to the resonance period, but may be a resonance frequency, and when the fire power is adjusted according to the resonance frequency, the resonance frequency is decreased to decrease the fire power and the resonance frequency is increased to increase the fire power because the frequency is the reciprocal of the period.
