Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
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, etc., and the present embodiment is not limited thereto.
As shown in fig. 1, the heating control method includes:
Generally, a temperature sensor is arranged on a cover body of the cooking appliance, and a probe of the temperature sensor extends to a pot body and is used for detecting temperature information of the top of the pot body. The coupler is usually arranged at the position where the cover body is connected with the pot body, and the temperature sensor detects temperature information and then sends the temperature information 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 body is lower than 100 ℃ before the food enters the boiling state, and when the temperature reaches 100 ℃ or more with heating, the food in the pot body starts to boil, and normally, the temperature continuously rises. The controller may further determine whether the food enters the boiling state according to the pressure in the pot body, which is not limited in this embodiment.
In practical applications, it is found that such an abnormal situation may exist: since the coupler is usually disposed at the joint position of the cover and the pot, food may be accumulated on the coupler when the cooking appliance is used for a long time or food is cooked, or temperature information may not be detected or suddenly changed after the food in the pot enters a boiling state due to other unknown reasons. As shown in the temperature curve of fig. 2, when the temperature information rises to about 104 ℃, the temperature information suddenly disappears and cannot be detected, and at this time, the controller considers that the system is in failure, stops heating, and thus the 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 pot body enters the boiling state. Here, T2 is, for example, 101 ℃, T4 is, for example, 130 ℃, and the above numerical values are merely illustrative of the present application, and the present embodiment is not limited thereto.
Because the control method of the present embodiment is executed after the food in the pot body is boiled, it is necessary to ensure that the method of the present embodiment is executed after the food in the pot body is boiled, and therefore, whether the detected temperature information suddenly becomes small or suddenly becomes large is detected after the food in the pot body is boiled, where the small means that the temperature information is less than the first preset temperature T2, and the T2 is less than or equal to the temperature information in the boiling state, that is, the temperature in the pot body becomes small after exceeding the boiling temperature, which indicates that the detected temperature information is inaccurate at this time; the larger is that the temperature information is greater than or equal to a second preset temperature T4, and the second preset temperature T4 is a high temperature failure temperature threshold of the temperature sensor, T2 < T4. The high temperature failure threshold of the temperature sensor is assumed to be 130 ℃, namely, the temperature is exceeded, the temperature sensor fails, and if the temperature information is suddenly detected to exceed T4 by the controller after the temperature sensor enters the boiling state, the temperature information is inaccurate at the moment.
Preferably, the cooking utensil 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 at preset power so as to gradually reduce the pressure and/or temperature in the pot body until the cooking is finished.
If the detected temperature information is less than the first preset temperature T2, or is greater than or equal to the second preset temperature T4, it indicates that the temperature information is inaccurate, but if the heating is stopped due to the abnormal temperature information, the cooking is interrupted, and the food in the pot is not cooked at this time, in this embodiment, the controller continues to heat with the predetermined power when detecting that the temperature information satisfies the condition in step 101, so that the pressure and/or the temperature in the pot are gradually reduced until the cooking is finished. The temperature curve at this time is as shown in fig. 3, and the temperature gradually decreases.
Here, the predetermined power is usually low power heating, for example, if the controller knows that the temperature information is detected inaccurately at this time, the controller does not continue to control the heating power based on the temperature information, but since the food in the pot body enters the boiling state before, which indicates that the pressure in the pot body reaches the high pressure state, the low power heating can be performed with the preset heating power, for example, 800W, and the cooking can be continued to stew the food, so that the food can be cooked after the food is boiled and when the temperature detection is inaccurate, and the cooking effect can be ensured.
In a preferred implementation, as shown in fig. 4, the heating control method includes:
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 ambient, for example a temperature near 0 c, which may be 2 c, for example. If the detected temperature information is smaller than the low-temperature failure threshold of the temperature sensor before the temperature enters the boiling state during cooking, and actually, the detected temperature information is an unreasonable detection result, the temperature sensor fails, the detected temperature information is wrong, and the controller can directly control the cooking appliance to stop heating.
Preferably, the controller can also send an alarm message while stopping heating, for example, activating an alarm device on the cooking appliance to alarm.
And 403, if yes, heating at a preset power to gradually reduce the pressure and/or temperature in the pot body until the cooking is finished.
Step 402 and step 403 may be performed in a similar or identical manner as step 101 and step 102, and are not described in detail herein.
By the heating control method, whether the temperature sensor fails or not and whether the temperature information is accurate or not can be judged by combining the low-temperature failure threshold value of the temperature sensor and the detected temperature information during normal heating, and heating is stopped when the temperature sensor is determined to fail, so that the problem that equipment is damaged due to out-of-control heating of a cooking appliance under abnormal conditions is solved.
In a preferred implementation, as shown in fig. 5, the heating control method includes:
And 502, if yes, heating at a preset power so as to gradually reduce the pressure and/or temperature in the pot body until the cooking is finished.
Step 501 and step 502 may be performed in a similar or identical manner as step 101 and step 102, and are not described herein again.
The fourth preset temperature T3 is a high-temperature alarm temperature threshold of the temperature sensor, and T3 is less than T4.
Specifically, after the food in the pot body enters the boiling state, if it is detected that the 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 boiling, it indicates that the cooking process is in a normal cooking process. If the detected temperature information is greater than the high-temperature alarm temperature threshold T3 of the temperature sensor and less than the high-temperature failure temperature threshold T4 of the temperature sensor, it indicates that the temperature is too high at this time, but the temperature sensor is not burned out, and at this time, if the temperature continues to be heated, the temperature continues to rise to exceed T4, and thus the temperature sensor is burned out.
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 decreased to be less than the fourth preset temperature T3, the heating is restarted.
Specifically, when the temperature information is reduced to be less than the fourth preset temperature T3, that is, less than the high temperature alarm temperature threshold of the temperature sensor, which indicates that the temperature sensor is safe and heating can be continued, the controller may restart the heating assembly to heat.
Through this implementation, can protect temperature sensor in real time at the culinary art in-process, avoid temperature sensor high temperature and burn, can guarantee the culinary art effect again when the protection device.
Preferably, before the food in the pot body enters the boiling state, the temperature information is lower than the boiling temperature under the normal condition, if the temperature information is detected to be greater than or equal to the second preset temperature T4, namely the temperature information is greater than the high-temperature failure temperature threshold value of the temperature sensor, the temperature sensor fails 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 appliance normally works or not 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 appliance is protected.
In a preferred implementation, the "predetermined power" in step 102 may be determined by: and acquiring food weight information in the pot body, and determining the preset power according to the food weight information.
Specifically, the controller may estimate the weight information of the food in the pot based on the time taken to preheat the food in the pot to a certain temperature at the initial heating. The heavier the food, the longer the warm-up time. It is understood that the food weight information in the pot body may be obtained in other manners, and the embodiment is not limited thereto.
After the food weight information in the pot body is acquired, the controller can determine the predetermined power according to the food weight information, for example, if the food weight value is larger, the value of the predetermined power selected in the selectable range is larger, and if the food weight is lighter, the value of the predetermined 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, the controller may further obtain the bottom temperature of the pot body according to a bottom temperature sensor provided at the bottom of the pot body, and then adjust the predetermined power according to the bottom temperature. For example, if the temperature of the bottom of the pan body is detected to be higher than a preset value, the preset power selects a smaller power value in the selectable range or directly stops heating, and when the temperature of the bottom of the pan body is reduced to be lower than the preset value, the 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 dry heating of a cooking utensil is avoided.
In some optional 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 here includes, but is not limited to, cooking rice, stew, soup, porridge. For example, a plurality of selection keys may be provided on a display panel of the cooking appliance to correspond to a plurality of cooking functions.
The predetermined cooking power corresponding to each cooking function, for example, the predetermined power when cooking rice > the predetermined power when stewing meat > the predetermined power when cooking congee, may be set in advance in the program. If the user selects the rice function during cooking, the controller may select the predetermined cooking power determined by the cooking function when the cooking mode in step 102 is implemented during cooking, so as to reasonably cook food with low power and ensure cooking effect.
In some alternative implementations, the predetermined power may be determined in the following manner. For example, the predetermined power is less than or equal to the product of the rated power of the cooking appliance multiplied by 0.3 in case of the porridge cooking function, and less than or equal to the product of the rated power of the cooking appliance multiplied by 0.5 in case of the non-porridge cooking function. Namely, after the food in the pot body enters a boiling state and the temperature information is abnormal, when the controller cooks the food according to the preset power and the small power, the preset power corresponding to the porridge cooking function is the minimum, and the preset power can be 0.3 × rated power. The predetermined power for the other cooking functions may be 0.5 x nominal power. It is understood that, in practical applications, the value of the predetermined power may be set according to practical situations, and the embodiment is not limited thereto.
Through the heating control method of the embodiment, after the food in the pot body enters the boiling state, if the temperature information is detected to be less than T2 or more than or equal to T4, the temperature information is not detected accurately, and at the moment, the low-power cooking is carried out according to the preset power, so that the food in the pot body is stewed, the food waste is avoided, and the cooking effect is ensured.

An embodiment of the present invention provides a cooking appliance provided with a temperature sensor 61, a coupler 62, and a controller 63. The cooking appliance may be, for example, an electric pressure cooker, or may be another cooking appliance, and the embodiment is not limited thereto.
As shown in fig. 6, the coupler 62 is connected between the temperature sensor 61 and the controller 63. The temperature sensor 61 is used for detecting temperature information in the pot body of the cooking appliance and sending the temperature information to the controller 63 through the coupler 62. Preferably, the cooking utensil further comprises a cover body capable of covering the pot body, and the temperature sensor 61 is arranged on one side of the cover body facing the pot body.

In some optional implementations, the cooking appliance further includes a bottom temperature measuring device (not shown in the figure) disposed at the bottom of the pot body for detecting the bottom temperature of the pot body.
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, perhaps, when being greater than or equal to temperature sensor's high temperature inefficacy temperature threshold value, then it has been inaccurate to show temperature information, no longer continues to control according to temperature information, but cooks according to predetermined power for temperature or pressure in the pot body reduce gradually until the culinary art is finished, guarantee the culinary art effect.
