So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
The cooking state of the cooker is combined, the accumulated coefficient is preset, the accumulated temperature corresponding to the current temperature of the cooker is predicted, and the dry-burning prevention treatment is carried out only under the condition that the predicted accumulated temperature is larger than the preset dry-burning threshold temperature, so that early warning is carried out through the accumulated temperature in advance, the dry-burning prevention probability of the cooker is reduced, and the dry-burning prevention accuracy of the kitchen electrical equipment is also improved. In addition, the material of the cooker and the firepower of the kitchen electrical equipment do not need to be detected, so that the dry burning prevention processing process is simpler, and the dry burning prevention processing efficiency is improved.
Fig. 1 is a schematic flow chart of a dry burning prevention control method according to an embodiment of the present disclosure. As shown in fig. 1, the dry burning prevention control process includes:
step 101: the current temperature of a pot cooked on the kitchen electrical equipment is obtained.
In an embodiment of the present disclosure, a kitchen appliance includes: gas cookers, induction cookers, and the like. The current temperature of the pot cooked on the kitchen electrical equipment can be obtained through the temperature sensor, for example: the current temperature of a cookware cooked on the kitchen electrical equipment is obtained through the infrared temperature sensor, and of course, other non-contact temperature sensors can also be applied to the temperature sensor. The dry burning prevention control is carried out in real time, so that the temperature of the cookware can be collected according to the preset sampling frequency.
Step 102: and under the condition that the current temperature is greater than the accumulated initial temperature corresponding to the cooking state of the pot, obtaining the current accumulated temperature according to a preset accumulated coefficient, the current temperature, the stored previous temperature and the stored previous accumulated temperature.
In the embodiment of the disclosure, when the pot is used for cooking with water, under the condition that the water is in the boiling state, the pot can be determined to be in the boiling cooking state, and other states can be determined to be in the non-boiling cooking state. When the pot is in the boiling state, the temperature change of the pot is small, and the corresponding temperature is the boiling temperature of the pot.
When the cooker on the kitchen electric equipment is used for cooking, a normal cooking heating stage exists, and once a limited temperature is exceeded, a dry-burning phenomenon is possible to occur, and the monitoring can be carried out at the moment, so that the limited temperature, namely the accumulated initial temperature corresponding to the cooking state of the cooker, can be determined firstly.
In some embodiments, determining the cumulative starting temperature may include: and determining the current cooking state of the cookware, and determining the current accumulated initial temperature corresponding to the current cooking state according to the corresponding relation between the stored cooking state and the accumulated initial temperature. For example: the preset corresponding relationship between the cooking state of the pot and the accumulated initial temperature may include: the accumulated initial temperature corresponding to the boiling cooking state is the boiling temperature of the pot. The cumulative starting temperature corresponding to the non-boiling cooking state may be the boiling temperature plus the set temperature.
In some embodiments, the accumulated starting temperature may be determined according to the boiling temperature of the pot when the current temperature is greater than the first set temperature and the pot is in the boiling cooking state. And under the condition that the current temperature is higher than a second set temperature and the cooker is in a non-boiling cooking state, determining the second set temperature as the accumulated initial temperature, wherein the second set temperature is higher than the first set temperature.
When the pot is used for cooking with water, the corresponding boiling temperature generally exists, the boiling temperature can be different according to different types of pots and different firepower of electric shock equipment, and the value generally can be between 140 and 240 degrees. In some embodiments of the present disclosure, the first set temperature T1 may be slightly greater than the boiling temperature. When the pot carries out water cooking, the boiling temperature corresponding to the collected boiling cooking state can be obtained, and then the accumulated initial temperature is determined according to the boiling temperature. For example, the boiling temperature Tf may be determined as the cumulative starting temperature Tq. Alternatively, in some embodiments, since there is some deviation in the boiling temperature collected each time the bottom of the pot is kept boiling while cooking with water, the boiling temperature may be properly compensated when determining Tq, i.e., the cumulative starting temperature Tq may be the sum of the boiling temperature Tf and the compensation temperature T3. Preferably, the value of T3 is not less than 0, and the corresponding value range can be (3-10) ° c. Of course, the value of T3 may also be determined experimentally.
The second set temperature T2 is greater than the first set temperature T1 and greater than the boiling temperature of the pot. If the boiling temperature is (140 ℃.), (240 ℃), the value range of T2 can be (270. + -. 10 ℃), of course, the temperature is not limited to 250 ℃, 255 ℃, 285 ℃. Likewise, the specific T2 value may also be determined by large data collection analysis. When the pot is in the non-boiling cooking state, the second set temperature T2 can be determined as the accumulated starting temperature Tq.
Of course, if the current temperature is less than or equal to the first set temperature, which indicates that a period of time is left for dry-burning, the possibility of dry-burning of the cookware is low, and at this time, temperature accumulation is not needed, so that the accumulated initial temperature can be cleared. Thus, the accumulated temperature is reset, and the probability of misoperation is reduced.
Because the current temperature is greater than the accumulated initial temperature, the corresponding accumulated temperature needs to be estimated, and the dry burning prevention prediction is carried out in advance. At this time, the current temperature T can be obtained according to the preset accumulative factor niAnd the previous temperature T of preservationi-1And the previous cumulative temperature Qi-1To obtain the current accumulated temperature Qi. In some embodiments, the current temperature T may be based oniAnd the previous temperature T of preservationi-1Obtaining the current temperature difference value delta ti＝Ti-Ti-1(ii) a Then, according to a preset accumulative coefficient n, the current temperature difference delta tiAnd preservedPrevious accumulated temperature Qi-1Obtaining the current accumulated temperature Q through the formula (1)i；
Qi＝Qi-1+Sgn(Δti)*(|Δti|)n (1)
Where i is the current number of samples, QiFor the current accumulated temperature, Δ tiFor the current temperature difference, n is a preset integral coefficient, Sgn (Δ t)i) The sign of the current temperature difference. If Δ tiIf the value is greater than or equal to zero, the corresponding Sgn (delta t)i) Positive sign, otherwise negative sign. i is an integer greater than or equal to 1.
n is a preset accumulation coefficient, generally, n is a real number greater than 1, and the larger the value is, the faster the accumulation speed is, and the faster the dry burning judgment can be completed. Because temperature acquisition is carried out once before accumulation is carried out each time to obtain the current temperature of the cookware, the temperature sampling frequency is equal to the frequency of calling the formula to calculate. The frequency of temperature sampling also affects the speed of integration. When the sampling frequency increases, the rapid acquisition will result in a smaller temperature difference acquired each time, and the final accumulated temperature value Q will also be smaller. In some embodiments, the frequency of temperature sampling may be controlled between 0.25Hz-0.5Hz through analysis of the large data. Of course, the specific sampling frequency and the specific accumulation coefficient n may be configured before shipment according to different kitchen electrical equipment. For example: if the sampling frequency is 0.5HZ, the value range of n can be 1.5-3.
Of course, when the temperature integration is performed for the first time, Δ tiAnd the current accumulated temperature is the accumulated starting temperature. And then, continuously accumulating according to the formula (1) on the first accumulated temperature to obtain the current accumulated temperature acquired each time.
Step 103: and carrying out dry burning prevention treatment under the condition that the current accumulated temperature is greater than the preset dry burning threshold temperature.
The current accumulated temperature corresponding to the current collection is accumulated through the preset accumulated coefficient, so that the current accumulated temperature is compared with the preset dry-heating threshold temperature, and dry-heating prevention treatment can be performed if the current accumulated temperature is greater than the preset dry-heating threshold temperature. The specific anti-dry heating treatment can adopt the existing related anti-dry heating treatment, and comprises at least one of the following modes: and (4) turning off the air source and the power supply, performing sound-light alarm, sending warning information to the control terminal, performing network alarm and the like.
It can be seen that, in this embodiment, the cooking state of the pot is combined, the preset accumulation coefficient is combined, the accumulation temperature corresponding to the current temperature of the pot is predicted, and the dry-burning prevention processing is performed only when the predicted accumulation temperature is greater than the preset dry-burning threshold temperature, so that the early warning is performed in advance, the dry-burning prevention probability of the pot is reduced, and the dry-burning prevention accuracy of the kitchen electrical equipment is also improved. In addition, the material of the cooker and the firepower of the kitchen electrical equipment do not need to be detected, so that the dry burning prevention processing process is simpler, and the dry burning prevention processing efficiency is improved.
Certainly, after the current accumulated temperature is obtained, the current temperature and the current accumulated temperature need to be stored, so that the temperature accumulation can be carried out when the temperature is collected next time, and the continuity of dry combustion early warning is guaranteed.
The following operational procedures are integrated into the specific embodiments to illustrate the anti-dry heating control process provided by the embodiments of the present invention.
In the embodiment of the disclosure, the accumulated initial temperature corresponding to the cooking state of the pot can be extracted for configuration, and can also be determined according to the collected temperature.
Fig. 2 is a schematic flow chart of cumulative starting temperature determination according to an embodiment of the disclosure. As shown in fig. 2, the process of cumulative start temperature determination includes:
step 201: determine whether the collected temperature is greater than a first set temperature T1? If so, go to step 202, otherwise, go to step 206.
Step 202: determine whether the pot is in a boiling cooking state? If so, go to step 203, otherwise, go to step 204.
Step 203: and determining the sum of the boiling temperature of the cooker and the preset compensation temperature as the accumulated initial temperature.
Step 204: determine whether the collected temperature is greater than a second set temperature T2? If yes, go to step 205, otherwise, this process ends.
Step 205: the second set temperature T2 is determined as the cumulative start temperature.
Step 206: and clearing the accumulated initial temperature.
Therefore, different accumulated initial temperatures are corresponding to the cooking states of different cookers, so that the accumulated temperature of the cooker is predicted by combining the cooking states of the cooker, and the accuracy of accumulated temperature prestoring is improved.
Fig. 3 is a schematic flow chart of a dry burning prevention control method according to an embodiment of the present disclosure. As shown in fig. 3, the dry burning prevention control process includes:
step 301: according to the sampling frequency of 0.5HZ, acquiring the current temperature T of a pot cooked on the gas cookeri。
Step 302: determine if the cumulative start temperature Tq is equal to zero? If not, go to step 303, and if so, go to step 309.
Here, the accumulated starting temperature Tq corresponds to the cooking state of the pot, and may be preset in advance according to the cooking state, or determined according to the above step 201 and 206.
Step 303: judging the current temperature TiIs greater than the cumulative start temperature Tq? If yes, go to step 304, otherwise, go back to step 301.
Step 304: according to the current temperature TiAnd the previous temperature T of preservationi-1Obtaining the current temperature difference value delta ti。
Step 305: according to a preset accumulative coefficient n, the current temperature difference delta tiAnd the stored previous accumulated temperature Qi-1To obtain the current accumulated temperature Qi。
Here, the current accumulated temperature Q can be obtained by the formula (1)i。
Qi＝Qi-1+Sgn(Δti)*(|Δti|)n (1)
Wherein, Sgn (delta t)i) Is the current temperatureSign of the degree difference value. If Δ tiIf the value is greater than or equal to zero, the corresponding Sgn (delta t)i) Positive sign, otherwise negative sign.
Step 306: saving the current temperature Ti and the current accumulated temperature Qi。
Step 307: judging the current accumulated temperature QiIs greater than a preset dry-fire threshold temperature? If yes, go to step 308, otherwise, go back to step 301.
Step 308: the gas source of the gas cooker is ignited, and acousto-optic warning is carried out.
Step 309: will be the current accumulated temperature QiAnd (6) clearing.
Therefore, in the embodiment of the disclosure, the cooking state of the pot is combined with the preset accumulation coefficient, the accumulation temperature corresponding to the current temperature of the pot is predicted, and the dry-burning prevention treatment is performed only under the condition that the predicted accumulation temperature is greater than the preset dry-burning threshold temperature, so that the early warning is performed in advance, the dry-burning prevention probability of the pot is reduced, and the dry-burning prevention accuracy of the kitchen electrical equipment is also improved. When the current temperature is lower than Tq, the integration is not performed, and when the temperature oscillates repeatedly, for example: the small kitchen range/waterless cooking is easy to cause repeated temperature oscillation, the accumulation speed is reduced, and misjudgment is avoided.
According to the above-mentioned process of preventing dry-burning control, a device for preventing dry-burning control can be constructed.

where i is the current number of samples, QiFor the current accumulated temperature, Δ tiFor the current temperature difference, n is a preset integral coefficient, Sgn (Δ t)i) The sign of the current temperature difference.
In some embodiments, the apparatus comprises: and the storage module is configured to store the current temperature and the current accumulated temperature.
The following illustrates an anti-dry heating control process performed by the anti-dry heating control device provided in the embodiment of the present disclosure.
Fig. 5 is a schematic structural diagram of an anti-dry heating control device provided in the embodiment of the present disclosure. As shown in fig. 5, the dry-heating prevention control device includes: the temperature acquisition module 410, the temperature accumulation module 420 and the dry-fire control module 430 further include: a first start determination module 440, a second start determination module 450, a zero module 460, and a save module 470.
Wherein, the temperature acquisition module can acquire the current temperature T of a cookware cooked on the cooker according to the set sampling frequencyi. And when the current temperature is greater than the first set temperature and the pot is in the boiling cooking state, the first start determining module 440 may determine the sum of the boiling temperature of the pot and the preset compensation temperature as the accumulated start temperature.

Of course, the zero module 460 may also zero the accumulated temperature in the event that the accumulated start temperature is zero.
Therefore, in the embodiment, the dry-burning prevention control device is combined with the cooking state of the pot and the preset accumulative coefficient to predict the accumulative temperature corresponding to the current temperature of the pot, and the dry-burning prevention treatment is performed only under the condition that the predicted accumulative temperature is greater than the preset dry-burning threshold temperature, so that early warning is performed in advance, the dry-burning prevention probability of the pot is reduced, and the dry-burning prevention accuracy of the electric kitchen equipment is also improved. When the current temperature is lower than the integration start temperature, the integration is not performed, and when the temperature oscillates repeatedly, for example: the small kitchen range/waterless cooking is easy to cause repeated temperature oscillation, the accumulation speed is reduced, and misjudgment is avoided.
