0442, calculating the ratio of the difference value to the preset period delta t as the temperature change trend A.

In some embodiments,

steps

0441 and 0442 can be implemented by the processor 104. That is, the processor 104 is further configured to: calculating a second temperature x₁And th temperature x₁A difference of (d); and calculating the ratio of the difference value to the preset period delta t to serve as the change trend A.

In particular, the second temperature x₂For a temperature at the end time of preset periods deltat (i.e., a temperature at the current time), a temperature x₁Is the temperature at the start of the preset period deltat. For example, the preset period Δ t is 10 seconds, and when the temperature change trend a in the preset period corresponding to the time length of 10S from 10 seconds to 20 seconds is required to be calculated, where the current time is 20 seconds, the second temperature x is₂The temperature obtained at the 20 th second is th temperature x₁The temperature at which the preset period deltat is 10 seconds long is pushed forward from the 20 th second, that is, the th temperature x₁The temperature obtained at the 10 th second. For another example, the preset period is 10 seconds, and when the temperature change trend a in the preset period corresponding to the 10S duration from the 12 th second to the 22 nd second at the current time is required to be calculated, the second temperature x is calculated₂The temperature obtained at the 22 nd second time, and the th temperature x₁The temperature at which the preset period deltat is 10 seconds long is pushed forward from the 22 nd second, i.e. the th temperature x₁The temperature obtained at the 12 th second. No matter which temperature variation trend in the time period corresponding to the preset period is calculated, the second temperature x is calculated₂And th temperature x₁Making a difference value, and taking the ratio of the difference value to a preset period delta t as the temperature change trend A in the time period, namely

If the current time is the 20 th second, the calculated temperature change trend is the temperature change trend in a preset period (within the time period of 10S from the 10 th second to the 20 th second) in which the 20 th second is located, and the 20 th second is the termination time of the time period; if the current time is 22 seconds, the calculated temperature change trend is the temperature change trend in a preset period (within the period of 10S from 12 seconds to 22 seconds) in which the 22 th second is located, and the 22 th second is the termination time of the period.

More specifically, if the preset period Δ t is 10 seconds, the temperature detected by the temperature sensing probe 112 at the 22 nd second time is 92 degrees celsius, that is, the second temperature x₂92 degrees celsius, the temperature measured by the temperature sensing probe 112 at the 12 th second is 83 degrees celsius (it should be noted that temperature data measured by the temperature sensing probe 112 are stored in the processor 104 or other storage element) which is advanced from the 22 nd second to the 10 th second by the preset period Δ t, that is, the th temperature x₁. The temperature change trend a (92 c to 83 c)/10S of the preset period (the period of the 10S duration from the 12 th second to the 22 nd second) at the 22 nd second is 0.9 c/S. In this way, the temperature variation trend a in the preset period at each moment can be accurately determined, and the moment is taken as the termination moment of the preset period.

Referring to fig. 2 and 9, in some embodiments, the number of the temperatures acquired in the preset period is a preset number, and step 044 (i.e., acquiring the temperature variation trend and the temperature fluctuation degree in the preset period according to a plurality of temperatures) includes:

0443, calculating the average value of the preset number of temperatures in the preset period;

0444, calculating the deviation between each temperature and the average value in a preset period;

0445, calculating the sum of all deviations in a preset period; and

0446, the ratio of the sum to a preset number is calculated as the degree of temperature fluctuation.

In some embodiments, the number of temperatures acquired during the preset period is a preset number. Step 0443, step 0444, step 0445 and step 0446 may be implemented by the processor 104, that is, the processor 104 may be configured to: calculating the average value of the preset number of temperatures in the preset period; calculating the deviation between each temperature and the average value in a preset period; calculating the sum of all deviations in a preset period; and calculating the ratio of the sum to a preset number as the fluctuation degree.

Specifically, taking an example in which the temperature detection device (e.g., the temperature sensing probe 112) collects the temperature of the pot 200 times every 2 seconds, the preset period may be, for example, 10 seconds, and if the current time is the 20 th second, the start time of the time period corresponding to the preset period is the 10 th second, and the end time is the 20 th second, and the temperatures of the corresponding pot 200 are obtained at the 10 th, 12 th, 14 th, 16 th, 18 th, and 20 th seconds, respectively, so that generates 6 temperatures x in total₁～x₆If the current time is 22 seconds, the starting time of the time period corresponding to the preset period is 12 seconds, the ending time is 22 seconds, the corresponding temperatures of the pot 200 are obtained respectively at 12 seconds, 14 seconds, 16 seconds, 18 seconds, 20 seconds and 22 seconds, also generate 6 temperatures x₁～x₆In embodiments, a preset number (6) of temperatures x are obtained₁～x₆Thereafter, the degree of fluctuation can be determined

And calculating the temperature fluctuation degree in the preset period at each moment, wherein the moment is used as the termination moment of the preset period. Wherein x is_iFor each temperature collected during a preset period,

the average value of the preset number of temperatures in the preset period is shown, and i is the preset number. For example, the preset period is 10S, the preset number is 6, and the 6 temperatures are x₁、x₂、x₃、x₄、x₅、x₆Then, then

Degree of fluctuationTherefore, the temperature fluctuation degree can be accurately determined, wherein when the preset period is too short, the temperature change is possibly not obvious enough, so that the temperature change trend is difficult to determine, and when the preset period is too long, the water possibly boils within the collection time of the temperature, so that the water boiling cannot be detected at the th time, and the subsequent cooking operation is influenced, therefore, the preset period can be [10S, 60S ]]Any value in between, for example, 10S, 11S, 12S, 13S, 14S, 15S, 16S, 17S, 18S, 19S, 25S, 26S, 29S, 30S, 35S, 40S, 45S, 50S, 55S, 58S, 59S, and 60S, and so forth. The preset number of temperatures may be any number, for example, 2, 3, 4, 5, 6 or more, and the more the number of the collected temperatures is selected, the more accurate the calculated temperature fluctuation degree is. More specifically, the value range of the preset number of the temperatures in the embodiment of the present application is [5, 30]]That is, 5 temperatures, 6 temperatures, 7 temperatures, 8 temperatures, 9 temperatures, 10 temperatures, 11 temperatures, 12 temperatures, 13 temperatures, 14 temperatures, 15 temperatures, 16 temperatures, 19 temperatures, 20 temperatures, 25 temperatures, 30 temperatures, etc. collected by the temperature detection device may be selected in a preset period, if the preset period is 10S, 6 temperatures collected in the preset period may be selected, temperatures may be collected every 2 seconds from the start time, as described above, if the start time of the preset period is 10 seconds, the 20 seconds at the end time may be respectively obtained at 10 seconds, 12 seconds, 14 seconds, 16 seconds, 18 seconds, 20 seconds, and collects 6 temperatures x and 32 seconds in total₁～x₆The processor 104 selects all of the 6 temperatures collected by the temperature detection device. The preset periods of other time lengths and the number of the collected temperatures can be similar to the preset periods of other time lengths, and the collection of the temperature at equal intervals can be carried out, and the collection of the temperature at unequal intervals can also be carried out.

In other embodiments, the temperature detection device may acquire temperatures at all times, for example, every half second, but the processor 104 only acquires a preset number of temperatures, for example, only acquires 6 temperatures acquired at 10 th, 12 th, 14 th, 16 th, 18 th, and 20 th seconds, and the acquired temperatures at 10.5 th, 11 th, and 11.5 th seconds are not acquired, i.e., are not used for calculating the temperature fluctuation degree.

More specifically, taking an example that the temperature detection device (for example, the temperature sensing probe 112) acquires the temperature of the pot 200 times every 2 seconds, if the preset period Δ t is 10 seconds, and the temperature fluctuation degree B in the preset period (i.e., in the 10 th to 20 th periods) in the 20 th second needs to be calculated, the temperature sensing probe 112 acquires that the temperature of the pot 200 corresponding to the current time (the 20 th second) is 90 degrees celsius, and then acquires, from the processor 104 (or other storage elements of the cooking appliance 100), other temperatures within the preset period Δ t of 10 seconds, that is, the temperatures of the pot 200 acquired in the 10 th, 12 th, 14 th, 16 th, and 18 th seconds, which are 80 degrees celsius, 83 degrees, 85 degrees, 86 degrees, and 89 degrees celsius in sequence.

According to the degree of fluctuation

The temperature fluctuation degree B in the preset cycle in which the 20 th second is located (i.e., in the 10 th to 20 th periods) was calculated to be 2.83. If it is required to calculate the temperature fluctuation degree B in the preset period of the 22 th second (i.e. in the period from 12 th second to 22 th), the temperature sensing probe 112 obtains the temperature of the pot 200 corresponding to the current time (22 th second) as 92 degrees celsius, and then obtains other temperatures in the preset period Δ t of 10 seconds from the processor 104 (or other storage elements of the cooking utensil 100) as: the temperatures of the cookware 200 collected at 12 th, 14 th, 16 th, 18 th and 20 th seconds are 83 degrees celsius, 85 degrees celsius, 86 degrees celsius, 89 degrees celsius and 90 degrees celsius in sequence.

According to the degree of fluctuation

The temperature fluctuation degree B in the preset cycle (i.e., in the 12 th to 22 nd periods) at the 22 nd second was calculated to be 2.83.

Referring to fig. 2 and 10, in some embodiments, the step 045 (i.e., determining whether the water is boiled according to at least of the comparison result of the temperature variation trend with the preset variation trend and the comparison result of the temperature fluctuation degree with the preset fluctuation degree) includes:

0451, boiling detection is carried out on water according to the temperature variation trend; wherein, step 0451 further comprises:

04511, judging whether the temperature variation trend is less than or equal to the preset variation trend;

04512, under the condition that the temperature variation trend is less than or equal to the preset variation trend, determining that the water boiling is finished;

and returning to the step 044 in the case that the temperature variation trend is greater than the preset variation trend.

In certain embodiments, step 0451, step 04511, and step 04512 may all be implemented by processor 104. That is, the processor 104 is also configured to perform boiling detection on the water according to the temperature trend. More specifically, the processor 104 is further configured to: judging whether the temperature variation trend is less than or equal to a preset variation trend or not; under the condition that the temperature variation trend is less than or equal to the preset variation trend, determining that the water is boiled and the water boiling is finished; and returning to the step of acquiring the temperature variation trend and the temperature fluctuation degree in the preset period according to the plurality of temperatures under the condition that the temperature variation trend is greater than the preset variation trend.

Specifically, when the temperature variation trend is smaller than or equal to the preset variation trend, the temperature variation of the water is relatively small, and the water boiling can be determined to be finished only under the condition that the temperature variation trend is smaller than or equal to the preset variation trend, so that the boiling detection difficulty is reduced. In the case that the temperature variation trend is larger than the preset variation trend, it is stated that the temperature variation of the water is large (the temperature of the water is still rising), that is, the water is still in the process of boiling, and at this time, the heating needs to be continued.

Referring to fig. 2 and 11, in some embodiments, the step 045 (i.e., determining whether the water is boiled according to at least of the comparison result of the temperature variation trend with the preset variation trend and the comparison result of the temperature fluctuation degree with the preset fluctuation degree) includes:

0452, boiling detection is carried out on water according to the temperature fluctuation degree; wherein, step 0452 further comprises:

04521, judging whether the temperature fluctuation degree is less than or equal to the preset fluctuation degree;

04522, determining that the boiling of water is completed when the temperature fluctuation degree is less than or equal to the preset fluctuation degree;

in the case where the temperature fluctuation degree is larger than the preset fluctuation degree, the process returns to step 044.

In certain embodiments, step 0452, step 04521, and step 04522 may all be implemented by processor 104. That is, the processor 104 is further configured to: and carrying out boiling detection on the water according to the temperature fluctuation degree. More specifically, the processor 104 is further configured to: judging whether the temperature fluctuation degree is less than or equal to a preset fluctuation degree or not; determining that the water is boiled and the water boiling is finished under the condition that the temperature fluctuation degree is less than or equal to the preset fluctuation degree; and returning to the step of acquiring the temperature change trend and the temperature fluctuation degree in the preset period according to the plurality of temperatures under the condition that the temperature fluctuation degree is greater than the preset fluctuation degree.

Specifically, when the temperature fluctuation degree is less than or equal to the preset fluctuation degree, it is said that the fluctuation of the temperature of the water is relatively small, and it can be understood that, when the water is about to boil, the temperature fluctuation is relatively small, so that the temperature fluctuation degree is relatively small, that is, the water boiling is determined to be completed, and the accuracy of boiling detection is improved. In the case of a temperature fluctuation greater than the preset fluctuation, it is stated that the temperature fluctuation of the water is large, i.e. the water is still in the process of boiling, at which time heating can continue.

Referring to fig. 2 and 12, in some embodiments, the step 045 (i.e., determining whether the water is boiled according to at least of the comparison result of the temperature variation trend with the preset variation trend and the comparison result of the temperature fluctuation degree with the preset fluctuation degree) includes:

0453, boiling detection is carried out on water according to the temperature change trend and the temperature fluctuation degree; wherein, step 0453 further comprises:

04531, judging whether the temperature variation trend is less than or equal to the preset variation trend and the temperature fluctuation degree is less than or equal to the preset fluctuation degree;

04532, under the condition that the temperature variation trend is less than or equal to the preset variation trend and the temperature fluctuation degree is less than or equal to the preset fluctuation degree, determining that the water boiling is finished;

and returning to the step 044 under the condition that the temperature variation trend is greater than the preset variation trend and/or the temperature fluctuation degree is greater than the preset fluctuation degree.

In certain embodiments, step 0453, step 04531, and step 04532 may all be implemented by processor 104. That is, the processor 104 is further configured to: and carrying out boiling detection on the water according to the temperature change trend and the temperature fluctuation degree. More specifically, the processor 104 is further configured to: judging whether the temperature variation trend is less than or equal to a preset variation trend and the temperature fluctuation degree is less than or equal to a preset fluctuation degree; under the conditions that the temperature variation trend is less than or equal to the preset variation trend and the temperature fluctuation degree is less than or equal to the preset fluctuation degree, the water boiling is determined to be finished; and returning to the step of acquiring the temperature variation trend and the temperature fluctuation degree in the preset period according to the plurality of temperatures under the condition that the temperature variation trend is greater than the preset variation trend and/or the temperature fluctuation degree is greater than the preset fluctuation degree.

Specifically, in the case where the temperature variation trend is greater than the preset variation trend and the temperature fluctuation degree is less than or equal to the preset fluctuation degree, it is determined that the water boiling is not completed, the process returns to step 044 (i.e., boiling detection is performed on the water according to the temperature variation trend and the temperature fluctuation degree), and the heating is continued. Or under the condition that the temperature variation trend is less than or equal to the preset variation trend and the temperature fluctuation degree is greater than the preset fluctuation degree, the water boiling is judged to be not finished, the step 044 is returned (namely, the water is subjected to boiling detection according to the temperature variation trend and the temperature fluctuation degree), and the heating is continued. Or under the condition that the temperature variation trend is greater than the preset variation trend and the temperature fluctuation degree is greater than the preset fluctuation degree, the water boiling is judged to be not finished, the step 044 is returned (namely, the water is subjected to boiling detection according to the temperature variation trend and the temperature fluctuation degree), and the heating is continued. The water boiling is judged only when the temperature change trend is smaller than or equal to the preset change trend and the temperature fluctuation degree is smaller than or equal to the preset fluctuation degree, so that the condition that the temperature change trend is smaller due to other factors or the temperature fluctuation degree is smaller due to other factors is avoided, the water boiling is judged by mistake, and the accuracy of boiling detection is improved. Other factors may be due to errors in the temperature sensing probe 112 when sensing the temperature, etc.

Referring to fig. 2 and 13, in some embodiments, step 04 (i.e., boiling detection of water according to at least of temperature variation trend and temperature fluctuation degree) includes:

046, in a preset period, boiling detection is carried out on the water according to the temperature change trend A, the temperature fluctuation degree B, the temperature mean value C, the temperature variance D, the temperature sum value E, the temperature variation coefficient F and the temperature median G of the plurality of temperatures.

Specifically, the manner of acquiring the temperature variation trend a and the temperature fluctuation degree B is the same as that described above, and is not described herein again. In addition, the temperature mean value C means: a plurality of temperature data x acquired within a preset period Δ t_iThe ratio of the sum of (a) to the number of preset temperatures.

Referring to fig. 2 and 14, in some embodiments, the step 046 (i.e., boiling detection of water according to the temperature variation trend a, the temperature fluctuation degree B, the temperature mean C, the temperature variance D, the temperature sum E, the temperature variation coefficient F and the median G of temperature for a predetermined period) includes:

0461, forming vectors with dimensions by using the temperature change trend A, the temperature fluctuation degree B, the temperature mean C, the temperature variance D, the temperature sum E, the temperature variation coefficient F and the temperature median G of a plurality of temperatures;

0462 obtaining Euclidean distance L according to the -dimensional vector and the preset standard vector, an

0463, according to Euclidean distance L and preset distance threshold value L₀It is determined whether the water is boiling.

In some embodiments,

steps

0461, 0462 and 0463 can be implemented by the processor 104. that is, the processor 104 can be further configured to form -dimensional vectors from the temperature variation trend A, the temperature fluctuation degree B, the temperature mean C, the temperature variance D, the temperature sum E, the temperature variation coefficient F and the temperature median G of the plurality of temperatures, and to generate the -dimensional vectors and the predetermined standard vectorAcquiring an Euclidean distance L; and according to the Euclidean distance L and a preset distance threshold value L₀It is determined whether the water is boiling.

Specifically, the -dimensional vector is -dimensional vectors a, B, C, D, E, F, G formed by a temperature change trend a, a temperature fluctuation degree B, a temperature mean C, a temperature variance D, a temperature sum E, a temperature variation coefficient F, and a temperature median G, and the processor 104 of the cooking appliance 100 further stores a standard vector corresponding to the -dimensional vector in advance, and a₀，B₀，C₀，D₀，E₀，F₀，G₀Euclidean distance L is obtained according to the relation between -dimensional vectors and standard vectors, specifically, Euclidean distance L is obtained according to -dimensional vectors A, B, C, D, E, F and G and standard vector A₀，B₀，C₀，D₀，E₀，F₀，G₀The sum of the squares of the differences of (a) and then the arithmetic square root of the sum. I.e. expressed by the mathematical formula:the Euclidean distance L and a preset distance threshold value L are compared₀The magnitude relationship of (a) to (b) yields whether the water is boiling. Specifically, the Euclidean distance L is less than or equal to L₀In case of (2), it is determined that the water is boiling.

Note that the standard vector A₀，B₀，C₀，D₀，E₀，F₀，G₀The temperature variation trend A, the temperature fluctuation degree B, the temperature mean value C, the temperature variance D, the temperature sum value E, the temperature variation coefficient F, the temperature median G and the standard vector A in the preset period of the current time are obtained according to the relational expression₀，B₀，C₀，D₀，E₀，F₀，G₀Obtaining the Euclidean distance L and comparing the Euclidean distance L with a preset distance threshold value L₀Comparing when the Euclidean distance L is less than or equal to L₀In the case of (1), the temperature change trend in the preset period at the current time is describedPotential A, temperature fluctuation degree B, temperature mean C, temperature variance D, temperature sum E, temperature variation coefficient F and temperature median G infinitely approximate to standard vector A₀，B₀，C₀，D₀，E₀，F₀，G₀In this case, therefore, it can be determined that the water is boiling. If the Euclidean distance L is larger than L₀Then it is determined that the water has not boiled and continued heating is required.

Referring to fig. 2 and 15, in some embodiments, after the step 042, if it is determined that the water is boiled, the water boiling control method may further include:

061, starting timing;

062, under the situation that the timing duration reaches the preset duration, determining that the water boiling is finished.

In the case where the water is not boiling, then step 042 continues.

In some embodiments, both steps 061 and 062 may be performed by the processor 104, i.e., after determining that the water is boiling, the processor 104 may be further configured to start a timer and, if the timer reaches a predetermined time, determine that the boiling of the water is completed, and, if the water is not boiling, continue to perform at least steps of detecting the boiling of the water according to a trend of temperature change and a degree of temperature fluctuation.

Specifically, after the water is determined to be boiled, needs to be heated continuously for a certain time, so that the water in the cooker 200 can be heated sufficiently, the situation that the water in the upper part of the cooker 200 is not completely boiled due to the fact that the heating is stopped immediately after the water is boiled is avoided, furthermore, the water is prevented from being excessively boiled when the water is determined to be completely boiled after a preset time period, more specifically, in some cooking processes, such as the dumpling cooking process, the water in the cooker 200 is heated after the dumpling is put into the cooker 200, and after the water in the cooker 200 is detected to be boiled after the water is detected to be boiled after the boiling detection, timing is started, so that the water is continuously heated for periods (such as 120 seconds), the dumpling is continuously boiled in the water for periods, the dumpling is guaranteed to be completely boiled, and the situation that the dumpling is not cooked due to the fact that the dumpling is completely boiled when the water is determined.

Referring to fig. 2 and 16, in some embodiments, after the step 042, the water boiling control method may further include:

063, in the event that it is determined that the water is boiling, reducing the current fire; and/or

064, prompting the user that the water is boiling;

in the case where the water is not boiling, then step 042 continues.

063 and 064 can be implemented by processor 104. That is, after determining that the water is boiling, the processor 104 may be further operable to: reducing the current fire power; and/or prompt the user that the water is boiling.

Specifically, after the boiling of water is detected, the current firepower is reduced to continue heating, and the energy loss is saved. The processor 104 controls the prompter to prompt boiling, so that the operation difficulty in the water boiling process is reduced, and the user experience is improved.

Referring to fig. 2 and 17, in some embodiments, after the step 042, if it is determined that the water is boiled, the water boiling control method may further include:

065, starting timing;

066, judging whether a dish placing action exists within a preset time;

067, under the condition that a dish placing action is carried out within a preset time, determining that water boiling is finished;

068, under the condition that no dish-taking action is performed within the preset time, the current firepower is adjusted to be the minimum firepower.

In the case where the water is not boiling, then step 042 continues.

In certain embodiments, step 065, step 066, step 067, and step 068 may all be implemented by processor 104. That is, after determining that the water is boiling, the processor 104 may be further operable to: starting timing; judging whether a dish-placing action exists within a preset time; under the condition that a dish placing action exists within a preset time, determining that water boiling is finished; and under the condition that no dish-taking action exists within the preset time length, the current firepower is adjusted to be the minimum firepower.

After determining that the water is boiling, if the processor 104 detects that the user has placed a dish in the pot 200 within a predetermined time period, it is determined that the water cooking is completed and a dish placing operation mode may be entered. If the processor 104 does not detect that the user has placed a dish in the pot 200 within the predetermined time period, the processor 104 controls the fire switch 114 to adjust the current fire power of the heating part 102 to the minimum fire power, thereby saving energy and preventing the pot from being dried.

Referring to fig. 2 and 18, in some embodiments, after the step 042, if it is determined that the water is boiled, the water boiling control method may further include:

069, judging whether the current temperature of the pot 200 is greater than or equal to the dry-out temperature;

070, when the current temperature of the pot 200 is greater than or equal to the dry-out temperature, prompting the user to dry out the water, and controlling the heating part 102 to stop heating;

continuing to execute step 069 when the current temperature of the cookware 200 is less than the drying temperature; in the case where the water is not boiling, the process continues to step 042.

In certain embodiments, both step 069 and step 070 may be implemented by processor 104. That is, the processor 104 is configured to implement: judging whether the current temperature of the pot 200 is greater than or equal to the dry-out temperature; when the current temperature of the pot is greater than or equal to the dry-out temperature, the user is prompted to dry out the water, and the heating part 102 is controlled to stop heating.

Specifically, setting the temperature for drying prevents the danger from occurring due to the water in the pot 200 being dried in case the user forgets to shut off the fire. When the temperature of the pot 200 reaches the temperature of dry-out, the processor 104 controls the prompter to prompt the pot 200 to dry-out the water, and controls the heating part 102 to stop heating. The occurrence of dangerous accidents can be avoided.
