[0045] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-3 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0046] The present application embodiment discloses a method for preventing dry burning. Figure 1 As an implementation method of preventing dry burning, the method includes the following steps:

[0047] Step 101: Acquire temperature data of the cookware in real time.

[0048] Specifically, an infrared sensor can be installed above the cooking appliance's heating element. The heating element can be any externally heated component, such as an induction cooker, electromagnetic range cooker, coal stove, or natural gas stove. The heating element can be a standalone device or integrated as a module in an integrated kitchen appliance (such as an integrated stove). When a user places a pot on the heating element, the infrared sensor detects the pot's temperature. The infrared sensor can communicate with the processor, either via wired or wireless communication. Once operational, the infrared sensor transmits the detected temperature data to the processor, allowing the processor to obtain the pot's temperature data.

[0049] Step 102: Determine the cookware state of the cookware based on the temperature data.

[0050] Specifically, the pot state of the cookware includes whether the cookware is placed on the heating component and whether the cookware is removed from the heating component, etc. The processor processes the acquired temperature data to obtain the pot state of the cookware.

[0051] Step 103: After determining that the cookware state is the first characteristic state, perform an anti-dry-boiling judgment step based on the temperature data and according to a preset data amount.

[0052] Specifically, the first characteristic state may be that the cookware is placed above a heating component that is in a working state and the cookware is in a state of gentle heating. After the processor determines that the cookware is in the first characteristic state, the processor performs an anti-dry-burn judgment step based on the temperature data and according to a preset data volume of the temperature data. By setting a preset data volume interval, the amount of data that needs to be processed when performing an anti-dry-burn judgment can be reduced.

[0053] Step 104: During the execution of the anti-dry-burn judgment step, when the temperature data meets the preset conditions, the anti-dry-burn confirmation step is executed.

[0054] Step 105: During the execution of the anti-dry-boiling confirmation step, when the temperature data is greater than a first preset value, a first control signal is sent; the first control signal is used to trigger the heating component for heating the cookware to stop heating.

[0055] Specifically, during the anti-dry-burn confirmation step, when the temperature data exceeds a first preset value, the processor sends a first control signal. This first control signal is an electrical signal. If the heating component is a natural gas stove or coal gas stove, for example, that uses liquefied gas for heating, the heating component can be stopped by controlling the valve body to close. The valve body can be a proportional valve, a motor valve, or a solenoid valve with electrically controlled opening and closing positions. If the heating component is a heating device that converts electrical energy into thermal energy, such as an induction cooker or electromagnetic range, the heating power can be controlled to stop the heating component.

[0056] In the present application, the temperature data of the cookware is acquired and the acquired temperature data is processed to identify the state of the cookware. After the state of the cookware is a first characteristic state, the anti-dry-burn judgment step is continuously and intermittently performed. During the execution of the anti-dry-burn judgment step, when the temperature data meets the preset conditions, the anti-dry-burn confirmation step is executed. During the execution of the anti-dry-burn confirmation step, when the temperature data is greater than a first preset value, a first control signal is sent, so that the heating component can be automatically stopped, thereby avoiding dry burning.

[0057] As a specific implementation of the anti-dry-boiling method, the step of determining whether the cookware state is a first characteristic state includes:

[0058] Obtaining a temperature average value of the N groups of data based on the obtained N groups of temperature data;

[0059] Obtaining a difference between each temperature data in the N sets of temperature data and the temperature average value based on the temperature average value; and

[0060] When the absolute values ​​of the N groups of difference values ​​are all smaller than the second preset value and the difference between the average value of the first N / 2 temperature data and the average value of the last N / 2 temperature data is within the preset characteristic interval, the cookware state is determined to be the first characteristic state.

[0061] Specifically, N sets of temperature data are processed based on a time series. For example, N sets of temperature data include a first set of temperature data, a second set of temperature data, and so on. After processing the N sets of temperature data, the original first set of temperature data is discarded and the original second set of temperature data is used as the new first set of temperature data. The remaining sets of temperature data are then sorted and shifted forward accordingly, with the most recently acquired set of temperature data being used as the last set of temperature data, thereby forming N new sets of temperature data. The value of N can be configured as needed, for example, N can be 14, 15, 16, etc. The processor calculates the average temperature value of the N sets of temperature data based on the current N sets of temperature data. For example, the processor can calculate the average temperature value of the N sets of temperature data by summing the N sets of temperature data and then dividing the sum by the total number N to obtain the average temperature value. The preset characteristic interval includes two symmetrical positive and negative intervals. The aforementioned "the difference between the average value of the first N / 2 sets of temperature data and the average value of the last N / 2 sets of temperature data is within the preset characteristic interval" can also be understood as the absolute value of the difference in the average values ​​being less than a certain value. When the absolute values ​​of the N groups of difference values ​​are all less than the second preset value and the difference between the average value of the first N / 2 temperature data and the average value of the last N / 2 temperature data is within the preset characteristic interval, the processor determines that the cookware state of the cookware is the first characteristic state. The first characteristic state can be understood as: the heating component is working, the cookware is placed above the heating component, and the cookware is in a state of gentle heating.

[0062] As a specific implementation of the anti-dry-burning method, the anti-dry-burning judgment step performed based on the preset data volume includes:

[0063] After determining that the state of the cookware is the first characteristic state, the anti-dry-boiling judgment step is executed after accumulating a first data amount of temperature data; thereafter, the anti-dry-boiling judgment step is executed every time a second data amount of temperature data is accumulated.

[0064] The preset condition includes a first preset condition, and the step of determining whether the temperature data satisfies the first preset condition includes:

[0065] Obtaining a first average difference based on the temperature data of the first data volume;

[0066] obtaining a second average value difference based on the temperature data of the second data amount acquired for the first time;

[0067] When the difference between the second average value difference and the first average value difference is greater than the third temperature value, it is determined that the temperature data meets the first preset condition.

[0068] Specifically, the data volume can be understood as the number of temperature data. The first data volume and the second data volume can be different or the same. When the first characteristic state is just entered, the processor obtains a first average value difference based on the temperature data of the first data volume, and obtains a second average value difference based on the temperature data of the second data volume obtained for the first time. When the difference between the second average value difference and the first average value difference is greater than the third temperature value, the processor determines that the temperature data meets the first preset condition, and the processor executes the anti-dry burning confirmation step.

[0069] As a specific implementation of the anti-dry burning method, the preset condition includes a second preset condition, and the step of determining whether the temperature data meets the second preset condition includes:

[0070] Obtaining an Mth average value based on the temperature data of the second data amount acquired for the Mth time; M≥2;

[0071] A first average value difference is obtained based on the Mth average value and the M-1th average value; the M-1th average value is the average value of the temperature data of the second data amount obtained for the M-1th time;

[0072] A second average difference is obtained based on the M-2th average value and the M-1th average value;

[0073] When the ratio of the first average value difference to the second average value difference is greater than the first ratio, it is determined that the temperature data meets the second preset condition.

[0074] Specifically, when the cookware enters the first characteristic state and the number of average values ​​obtained by the processor is greater than two, a judgment condition different from the first preset condition needs to be adopted. "The temperature data of the second data amount obtained for the Mth time" can be understood as the temperature data of the first data amount obtained before this, and the temperature data of the second data amount obtained for the first time can be understood as the temperature data of the second data amount obtained for the first time after the temperature data of the first data amount has been obtained again. After the average value of the acquired temperature data is greater than two, the processor obtains the Mth average value based on the temperature data of the second data amount obtained for the Mth time, obtains the first average value difference by the difference between the current average value and the previous average value, and obtains the second average value difference based on the difference between the previous average value and the previous average value. When the ratio of the first average value difference to the second average value difference is greater than the first ratio, the processor determines that the temperature data meets the second preset condition, and the processor executes the anti-dry burning confirmation step.

[0075] As a specific embodiment of the anti-dry-boiling method, the cookware state includes a second characteristic state, and the step of determining that the cookware state is the second characteristic state includes: when temperature data meets a third preset condition and continues for a preset first set of times, determining that the cookware state is the second characteristic state; the third preset condition includes: when, in Q groups of temperature data among N groups of temperature data, a first group of temperature data is less than a last group of temperature data, a difference between the first group of temperature data and the last group of temperature data is within a preset first temperature range, the first group of temperature data is less than or equal to the third group of temperature data, the third group of temperature data is less than or equal to the sixth group of temperature data, the first group of temperature data is the minimum value among the Q groups of temperature data, and the last group of temperature data is the maximum value among the Q groups of temperature data;

[0076] The anti-dry-boiling judgment step further includes: when the cookware changes from the first characteristic state to the second characteristic state and the difference between the temperature of the cookware when entering the second characteristic state and the temperature of the first characteristic state is not less than a fourth temperature, executing the anti-dry-boiling confirmation step.
