Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Example 1
The embodiment of the invention provides a heating control method for a cooking appliance.
The cooking device of the present embodiment may be, for example, a pressure cooker, an electric cooker, or the like, and the present embodiment is not limited thereto.
As shown in fig. 1, the heating control method includes:
In general, a temperature sensor is provided on a cover of the cooking appliance, and a probe of the temperature sensor extends to the pot for detecting temperature information of the top of the pot. The coupler is usually arranged at the position where the cover body is connected with the pot body, and after the temperature sensor detects the temperature information, the temperature information is sent to the controller through the coupler. The controller can receive the temperature information, acquire the cooking state of food in the pot body according to the temperature information, and adjust the heating power.
Here, the cooking state of the food in the pot body may include, for example, a preheating state, a boiling state, and the like. As an example, the temperature of the food in the pot is lower than 100 ℃ before the food enters the boiling state, and when the temperature reaches 100 ℃ and above as the food is heated, the food in the pot starts to boil, and the temperature continuously rises under normal conditions. The controller can also judge whether food enters a boiling state according to the pressure in the pot body, and the embodiment is not limited by the pressure.
In practical applications, it is found that such an abnormal situation exists: because the coupler is generally arranged at the joint position of the cover body and the pot body, the food can be accumulated on the coupler when the cooking appliance is used for a long time or the food is cooked, or the temperature information can not be detected suddenly or suddenly changes suddenly after the food in the pot body enters a boiling state due to other unknown reasons. As shown in conjunction with the temperature profile of fig. 2, when the temperature information rises to about 104 ℃, the temperature information suddenly disappears and is not detected, at which point the controller may consider the system to be malfunctioning, stopping heating, and thus cooking is interrupted.
In this embodiment, the controller may detect whether the temperature information is less than the first preset temperature T2 or greater than or equal to the second preset temperature T4 after the food in the pan body enters the boiling state. Here, T2 is 101 ℃, T4 is 130 ℃, for example, and the above values are only for explaining the present application, and the present embodiment is not limited thereto.
Since the control method of the embodiment does not cook the food if the food in the pot body does not enter boiling or the pressure in the pot body does not reach high pressure, it is necessary to ensure that the method of the embodiment is performed after the food in the pot body has been boiled, so that it is detected whether the temperature information suddenly becomes smaller or larger after the food in the pot body enters boiling, where smaller means that the temperature information is smaller than the first preset temperature T2 and T2 is smaller or equal to the temperature information in boiling, that is, the temperature in the pot body becomes smaller after exceeding the boiling temperature, the detected temperature information is inaccurate; the enlargement here means that the temperature information is greater than or equal to the second preset temperature T4, and the second preset temperature T4 is a high temperature failure temperature threshold value of the temperature sensor, and T2 is less than T4. The high temperature failure threshold of the temperature sensor is assumed to be 130 ℃, namely the temperature sensor fails when the temperature is exceeded, and if the controller suddenly detects that the temperature information exceeds T4 after the boiling state is entered, the temperature information is inaccurate at the moment.
Preferably, the cooking appliance is a pressure cooker, and the range of the first preset temperature T2 is as follows: t2 is more than or equal to 100 ℃ and less than or equal to 120 ℃.
And 102, if yes, heating with preset power to gradually reduce the pressure and/or temperature in the pot body until the cooking is finished.
If the detected temperature information is smaller than the first preset temperature T2 or greater than or equal to the second preset temperature T4, the temperature information is inaccurate, but if the heating is stopped due to the abnormal temperature information, the cooking is stopped, the food in the pot body is not cooked at the moment, in this embodiment, the controller continues to heat at the preset power when the detected temperature information meets the condition in the step 101, so that the pressure and/or the temperature in the pot body gradually decreases until the cooking is finished. The temperature profile at this time is shown in fig. 3, and the temperature gradually decreases.
Here, the predetermined power is usually low-power heating, for example, when the controller knows that the temperature information is inaccurate, the controller does not continue to control the heating power based on the temperature information, but because the food in the pot body has previously entered a boiling state, which indicates that the pressure in the pot body reaches a high-pressure state, the low-power heating can be performed with the preset heating power, for example, 800W, to continue cooking, and the food is braised, so that after the food is boiled, the food can be cooked even when the temperature detection is inaccurate, and the cooking effect is ensured.
In a preferred implementation, as shown in fig. 4, the heating control method includes:
in step 401, if the temperature information is detected to be less than the third preset temperature T1 before the food in the pan body enters the boiling state, heating is stopped.
Here, the third preset temperature T1 is a low temperature failure temperature threshold of the temperature sensor. The low temperature failure threshold is typically less than normal temperature, e.g., a temperature near 0 ℃, e.g., may be 2 ℃. If the detected temperature information is smaller than the low temperature failure threshold of the temperature sensor before the temperature does not enter the boiling state during cooking, in fact, the temperature sensor fails according to an unreasonable detection result, the detected temperature information is wrong, and the controller can directly control the cooking appliance to stop heating.
Preferably, the controller may also send an alarm message at the same time as stopping the heating, for example, starting an alarm device on the cooking appliance to alarm.
In step 402, if the food in the pan body enters the boiling state, it is detected whether the temperature information is less than the first preset temperature T2 or greater than or equal to the second preset temperature T4.
If yes, heating with a predetermined power to gradually decrease the pressure and/or temperature in the pot until the cooking is finished, step 403.
The steps 402 and 403 may be performed in a similar or identical manner to the steps 101 and 102, and will not be described in detail herein.
According to the heating control method, the low-temperature failure threshold value of the temperature sensor and the detected temperature information can be combined during normal heating to judge whether the temperature sensor fails and whether the temperature information is accurate, and when the temperature sensor is determined to fail, heating is stopped, so that the problem that the cooking utensil is out of control in heating under abnormal conditions and equipment is damaged is avoided.
In a preferred implementation, as shown in fig. 5, the heating control method includes:
in step 501, if the food in the pan body enters the boiling state, it is detected whether the temperature information is less than the first preset temperature T2 or greater than or equal to the second preset temperature T4.
The above steps 501 and 502 may be performed in a similar or identical manner to the steps 101 and 102, and will not be described in detail herein.
In step 503, after the food in the pan body enters the boiling state, if the detected temperature information is continuously greater than the first preset temperature T2 and the detected temperature information is between the fourth preset temperature T3 and the second preset temperature T4, the heating is stopped.
The fourth preset temperature T3 is a high-temperature alarm temperature threshold value of the temperature sensor, and T3 is smaller than T4.
Specifically, after food in the pan body enters a boiling state, if the detected temperature information is continuously greater than the first preset temperature T2, and the first preset temperature T2 is a temperature value close to the temperature at the time of boiling, this indicates that the food is in a normal cooking process at this time. If the detected temperature information is greater than the high-temperature alarm temperature threshold T3 of the temperature sensor and is smaller than the high-temperature failure temperature threshold T4 of the temperature sensor, the temperature is too high at the moment, but the temperature sensor is not burnt out, and at the moment, if the heating is continued, the temperature is continuously increased to exceed T4, so that the temperature sensor is burnt out, therefore, in the embodiment of the application, the controller can stop heating at the moment to wait for the temperature to gradually decrease.
Here, T3 may be 115 ℃, for example, and the present embodiment is not limited thereto.
In step 504, if it is detected that the temperature information is reduced to less than the fourth preset temperature T3, the heating is restarted.
Specifically, when the temperature information is reduced to be smaller than the fourth preset temperature T3, that is, smaller than the high-temperature alarm temperature threshold of the temperature sensor, the temperature sensor is safe at the moment, heating can be continued, and the controller can restart the heating component for heating.
Through this implementation mode, can protect temperature sensor in the culinary art in-process in real time, avoid temperature sensor high temperature and burn out, can guarantee the culinary art effect again when protecting the device.
Preferably, before food in the pot body enters a boiling state, the temperature information is normally lower than the boiling temperature, and if the temperature information is detected to be greater than or equal to a second preset temperature T4 at the moment, namely, the temperature information is greater than a high-temperature failure temperature threshold value of the temperature sensor, the temperature sensor is stopped at the moment, the detected temperature information is inaccurate, heating is stopped, and alarm information is prompted to remind a user.
Through the implementation mode, whether the cooking utensil works normally can be judged in real time by combining the detected temperature information in the cooking process, so that heating is regulated and controlled, and the utensil is protected.
In a preferred implementation, the "predetermined power" in step 102 may be determined by: food weight information in the pot body is acquired, and the preset power is determined according to the food weight information.
Specifically, the controller may estimate the weight information of the food in the pan based on the time it takes to preheat the food in the pan to a certain temperature at the time of initial heating. The heavier the food, the longer the warm-up time. It will be appreciated that other ways of obtaining weight information of food in the pan are also possible, and the embodiment is not limited thereto.
After the weight information of the food in the pot body is obtained, the controller can determine the preset power according to the weight information of the food, for example, if the weight value of the food is larger, the value of the preset power selected in the selectable range is larger, and the weight of the food is lighter, the value of the preset power selected in the selectable range is smaller, so that the heating power is reasonably controlled, and the cooking efficiency is improved.
As an alternative implementation manner, the controller may also acquire the bottom temperature of the pot according to a bottom temperature sensor provided at the bottom of the pot, and then adjust the predetermined power according to the bottom temperature. For example, when the temperature of the bottom of the pot body is detected to be higher than a preset value, the preset power is selected to be a smaller power value in a selectable range or heating is directly stopped, and when the temperature of the bottom of the pot body is reduced below the preset value, heating is continued with the preset power. Meanwhile, dry heating can be avoided, for example, when the temperature of the bottom of the pot body exceeds the dry heating early warning temperature, the controller can stop heating, and the dry heating of the cooking utensil is avoided.
In some alternative implementations, the predetermined power may also be determined by: the predetermined power is determined according to a current cooking function of the cooking appliance. Cooking power herein includes, but is not limited to, cooking rice, stewing meat, soup, porridge. For example, a plurality of selection keys corresponding to a plurality of cooking functions may be provided on a display panel of the cooking appliance.
The predetermined cooking power corresponding to each cooking function may be set in advance in the program, for example, a predetermined power when cooking rice > a predetermined power when stewing meat > a predetermined power when cooking porridge. If the rice function is selected by the user during cooking, the controller may select the predetermined cooking power determined by the controller according to the cooking function when the cooking mode of the cooking appliance in step 102 is implemented during cooking, so that the food is cooked reasonably with low power, and the cooking effect is ensured.
In some alternative implementations, the predetermined power may be determined by the following. For example, if the porridge cooking function is used, the preset power is smaller than or equal to the product of the rated power of the cooking appliance multiplied by 0.3, and if the porridge cooking function is not used, the preset power is smaller than or equal to the product of the rated power of the cooking appliance multiplied by 0.5. That is, when the temperature information is abnormal after the food in the pot body enters the boiling state, the preset power corresponding to the porridge cooking function is minimum when the controller cooks the food according to the preset power and the low power, and specifically, the preset power can be 0.3 x rated power. The predetermined power for the other cooking functions may be 0.5 rated power. It will be appreciated that in practical applications, the value of the predetermined power may be set according to practical situations, and the present embodiment is not limited thereto.
By the heating control method of the embodiment, after food in the pot body enters a boiling state, if the temperature information is detected to be smaller than T2 or larger than or equal to T4, the temperature information is inaccurately detected, and then the low-power cooking is performed according to the preset power, so that the food in the pot body is braised, and the cooking effect is ensured while the food waste is avoided.

Through the cooking utensil of this embodiment, can be after the food in the pot body gets into boiling state, if temperature information is less than boiling temperature, or when being greater than or equal to temperature sensor's high temperature failure temperature threshold value, it is inaccurate to indicate that temperature information has already been, does not continue to control according to temperature information, but cooks according to predetermined power for the internal temperature of pot or pressure drop gradually until the culinary art is accomplished, guarantees the culinary art effect.
