[0045] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0046] Example 1

[0047] This embodiment provides a method for detecting dry burning of a stove. Figure 1 As shown, including:

[0048] Step S1: Obtain vibration data collected by a vibration sensor, where the vibration sensor is installed on a pot or a spatula.

[0049] In a specific implementation, the vibration sensor can be installed on the bottom of the pot, on the spatula, or on the stove panel. The vibration data collected by the sensor installed on the bottom of the pot, on the spatula, or on the stove panel is obtained. The frequency of the vibration sensor collection depends on the actual situation.

[0050] Step S2: Acquire the current cooking mode based on the vibration data within a first preset time period.

[0051] In a specific implementation, the current cooking mode is determined by obtaining vibration data obtained by the sensor installed at the bottom of the pot, the spatula or the cooktop in step S1 within the first preset time. It should be understood by those skilled in the art that the first preset time can be set according to actual conditions. In an optional embodiment of step S2, see Figure 2 The vibration data may include vibration amplitude and vibration frequency, and the current cooking mode is obtained based on the vibration data within the first preset time period according to the following steps:

[0052] Step S201: Count and obtain the vibration frequencies within a first preset time period whose vibration amplitudes are greater than or equal to a preset first vibration amplitude threshold.

[0053] In a specific implementation, the vibration frequencies whose vibration amplitudes are greater than or equal to a preset first vibration amplitude threshold within a first preset duration are counted. If the vibration amplitude is less than the preset first vibration amplitude threshold, no statistics are performed. Those skilled in the art will appreciate that the first vibration amplitude threshold can be set based on actual conditions.

[0054] Step S202: If the vibration frequency is greater than or equal to the preset vibration frequency threshold, the current cooking mode is the stir-fry mode.

[0055] In a specific implementation, if the vibration frequency counted in step S201 is greater than or equal to a preset vibration frequency threshold, it can be determined that the cooking mode at that time is stir-fry mode, which means that someone is recognized to be operating the cookware. Those skilled in the art will understand that the vibration frequency threshold can be set according to actual circumstances.

[0056] In an optional embodiment, see Figure 3 , before step S2, specifically including the following steps:

[0057] Step S0021, when it is detected that the stove is ignited, the current temperature threshold is set to the third temperature threshold. Among them, the third temperature threshold is the highest. In a specific implementation, the mode corresponding to the third temperature threshold can be called the "ultimate anti-dry burning mode". When the user is cooking, when it is detected that the stove is ignited, the current temperature threshold is set to the third temperature threshold for the purpose of protecting the vibration sensor. The third temperature threshold is the highest temperature that the vibration sensor can bear. For example, the third temperature threshold is set to 400 degrees Celsius. When the temperature sensor (for example, NTC, negative temperature coefficient sensor) detects that the temperature exceeds 400 degrees Celsius, the fire is turned off to prevent the vibration sensor from being burned and scrapped by excessively high temperatures. Those skilled in the art should understand that the third temperature threshold can be set according to actual conditions.

[0058] In an optional embodiment, after step S0021, the following steps are specifically included:

[0059] Step S0022: When the vibration amplitude is greater than or equal to the preset second vibration amplitude threshold, the current temperature threshold is set to the second temperature threshold after waiting for a third preset time. The second temperature threshold is less than the third temperature threshold. When the vibration amplitude is greater than or equal to the preset second vibration amplitude threshold, it indicates that the cooker has been placed on the gas stove and is already cooking, but has not yet entered cooking mode. In a specific implementation, the mode corresponding to the second temperature threshold may be referred to as the "conventional anti-dry burn mode." During the cooking process, when the vibration amplitude is detected to be greater than or equal to the preset second vibration amplitude threshold, the current temperature threshold is set to the second temperature threshold after waiting for a third preset time. The third preset time can be set based on actual conditions and is typically set to 10 seconds. The purpose of setting the third preset time is to prevent the heat from being mistakenly turned off when the pan or oil is hot due to dry burn prevention. Therefore, the current temperature threshold is set to the second temperature threshold after a 10-second delay. The second temperature threshold can be set based on actual conditions and is typically set to 260 degrees Celsius. When the temperature sensor (e.g., NTC, negative temperature coefficient sensor) detects that the temperature exceeds 260 degrees Celsius, the fire is turned off to prevent dry cooking during cooking. Those skilled in the art will appreciate that the second temperature threshold can be set according to actual conditions.

[0060] Step S3, if the current cooking mode is the stir-fry mode, the current temperature threshold is set to the first temperature threshold. Among them, when the current cooking mode is the stir-fry mode, it means that a user is recognized to be operating the pot. At this time, the current temperature threshold can be set to the first temperature threshold, and the second temperature threshold is less than the first temperature threshold. Setting it to the first temperature threshold can effectively prevent the user from turning off the fire due to the misjudgment of anti-dry burning due to the temperature rise when stir-frying. In addition, the first temperature threshold is negatively correlated with the second preset time length. For example, when the first temperature threshold reaches 280 degrees Celsius, the second preset time length can be set to 30s (seconds). For another example, when the first temperature threshold reaches 400 degrees Celsius, the second preset time length can be set to 2s (seconds).

[0061] In an optional embodiment of step S3, see Figure 4 , including the following steps:

[0062] Step S301: When the current cooking mode is the stir-fry mode, obtain the number of vibrations within a second preset time period whose vibration amplitude is greater than or equal to a preset first vibration amplitude threshold.

[0063] The first temperature threshold is greater than the second temperature threshold and less than or equal to the third temperature threshold. The number of vibrations within the second preset time period with a vibration amplitude greater than or equal to the preset first vibration amplitude threshold is obtained, and the first vibration amplitude threshold is greater than the second vibration amplitude threshold.

[0064] Those skilled in the art should understand that the second preset duration and the first vibration amplitude threshold can be set according to actual conditions.

[0065] Step S302: If the vibration frequency is less than the frequency threshold, the current temperature threshold is set as a second temperature threshold.

[0066] When the vibration times acquired in step S301 are less than the number threshold, the cooking mode is exited, and the current temperature threshold is set to the second temperature threshold.

[0067] Step S4: When the temperature collected by the temperature sensor is greater than or equal to the current temperature threshold, it is determined that dry burning occurs.

[0068] In this embodiment, vibration data can be collected by the vibration sensor on the stove or spatula, and the vibration data within the first preset time period can be used to determine whether the cooking mode is in progress. The current temperature threshold can also be adjusted in time. When the user is in different cooking modes, different temperature thresholds correspond to different cooking modes, which can effectively prevent misjudgment of turning off the fire and more intelligently determine whether dry burning occurs, thereby improving the user's cooking experience.

[0069] Example 2

[0070] This embodiment provides a dry-burning detection system for a stove. Figure 5 Schematic diagram of the modules of this embodiment is shown. Figure 5 The dry burning detection system of the stove of this embodiment includes:

[0071] The data acquisition module 1 is used to acquire vibration data collected by a vibration sensor, where the vibration sensor is installed on the pot or spatula.

[0072] In a specific implementation, the vibration sensor can be installed on the bottom of the pot, on the spatula, or on the stove panel. The vibration data collected by the sensor installed on the bottom of the pot, on the spatula, or on the stove panel is obtained. The frequency of the vibration sensor collection depends on the actual situation.

[0073] The cooking mode acquisition module 2 is configured to acquire the current cooking mode based on the vibration data within a first preset time period.

[0074] In a specific implementation, the current cooking mode is determined by acquiring vibration data from a sensor mounted on the bottom of the cookware, a spatula, or a cooktop within a first preset time period in the data acquisition module 1. Those skilled in the art will appreciate that the first preset time period can be set based on actual circumstances. In an optional embodiment of the cooking mode acquisition module 2, the vibration data may include vibration amplitude and vibration frequency. The cooking mode acquisition module 2 includes:

[0075] The statistical unit is used to obtain the vibration frequency within the first preset time period whose vibration amplitude is greater than or equal to a preset first vibration amplitude threshold.

[0076] In a specific implementation, the vibration frequencies whose vibration amplitudes are greater than or equal to a preset first vibration amplitude threshold within a first preset duration are counted. If the vibration amplitude is less than the preset first vibration amplitude threshold, no statistics are performed. Those skilled in the art will appreciate that the first vibration amplitude threshold can be set based on actual conditions.

[0077] The vibration frequency comparison unit is used to determine that the current cooking mode is the stir-fry mode if the vibration frequency is greater than or equal to a preset vibration frequency threshold.

[0078] In a specific implementation, when the vibration frequency is greater than or equal to a preset vibration frequency threshold, it can be determined that the cooking mode at that time is stir-fry mode, which means that someone is recognized to be operating the cookware. Those skilled in the art will understand that the vibration frequency threshold can be set according to actual conditions.

[0079] In an optional embodiment, the dry burning detection system further includes:

[0080] The third temperature threshold setting module 021 is configured to set the current temperature threshold as the third temperature threshold when it is detected that the stove is ignited.

[0081] Among them, the third temperature threshold is the highest. In a specific implementation, the mode corresponding to the third temperature threshold can be called the "ultimate anti-dry burning mode". When the user is cooking, when the stove is detected to be ignited, the current temperature threshold is set to the third temperature threshold for the purpose of protecting the vibration sensor. The third temperature threshold is the highest temperature that the vibration sensor can bear. For example, the third temperature threshold is set to 400 degrees Celsius. When the temperature sensor (for example, NTC, negative temperature coefficient sensor) detects that the temperature exceeds 400 degrees Celsius, the fire is turned off to prevent the vibration sensor from being burned and scrapped by excessively high temperatures. Those skilled in the art should understand that the third temperature threshold can be set according to actual conditions.

[0082] In an optional embodiment, the second temperature threshold setting module 302 is further configured to: when the vibration amplitude is greater than or equal to a preset second vibration amplitude threshold, wait for a third preset time period before setting the current temperature threshold to the second temperature threshold. The second temperature threshold is less than the third temperature threshold. When the vibration amplitude is greater than or equal to the preset second vibration amplitude threshold, it indicates that the cooker has been placed on the gas stove and is cooking, but has not yet entered cooking mode. In a specific implementation, the mode corresponding to the second temperature threshold may be referred to as "conventional anti-dry burn mode." During the cooking process, when the vibration amplitude is detected to be greater than or equal to the preset second vibration amplitude threshold, the current temperature threshold is set to the second temperature threshold after waiting for a third preset time period. The third preset time period can be set based on actual conditions and is typically set to 10 seconds. The purpose of setting the third preset time period is to prevent the heat from being mistakenly turned off when the pan or oil is hot due to dry burn prevention. Therefore, the current temperature threshold is set to the second temperature threshold after a 10-second delay. The second temperature threshold can be set based on actual conditions and is typically set to 260 degrees Celsius. When the temperature sensor (e.g., NTC, negative temperature coefficient sensor) detects that the temperature exceeds 260 degrees Celsius, the fire is turned off to prevent dry cooking during cooking. Those skilled in the art will appreciate that the second temperature threshold can be set according to actual conditions.

[0083] The first temperature threshold setting module 3 is configured to set the current temperature threshold to the first temperature threshold if the current cooking mode is the stir-fry mode.

[0084] Among them, when the current cooking mode is the stir-fry mode, it means that a user is recognized as operating the pot. At this time, the current temperature threshold can be set to the first temperature threshold, and the second temperature threshold is less than the first temperature threshold. Setting it to the first temperature threshold can effectively prevent the user from turning off the fire due to misjudgment of anti-dry burning due to rising temperature when stir-frying. In addition, the first temperature threshold is negatively correlated with the second preset time length. For example, when the first temperature threshold reaches 280 degrees Celsius, the second preset time length can be set to 30s (seconds). For another example, when the first temperature threshold reaches 400 degrees Celsius, the second preset time length can be set to 2s (seconds).

[0085] In an optional embodiment, the dry burning detection system of the stove further includes:

[0086] The number acquisition module 301 is used to acquire the number of vibrations in which the vibration amplitude is greater than or equal to a preset first vibration amplitude threshold within a second preset time period when the current cooking mode is the stir-fry mode.

[0087] Wherein, the first temperature threshold is greater than the second temperature threshold and less than or equal to the third temperature threshold. The number of vibrations within the second preset duration whose vibration amplitude is greater than or equal to the preset first vibration amplitude threshold is obtained, and the first vibration amplitude threshold is greater than or equal to the second vibration amplitude threshold. It should be understood by those skilled in the art that the second preset duration and the first vibration amplitude threshold can be set according to actual conditions. The second temperature threshold setting module 302 is used to set the current temperature threshold to the second temperature threshold if the number of vibrations is less than the number threshold.

[0088] When the vibration times obtained in step S301 are less than the number threshold, the cooking mode is exited and the current temperature threshold is set to the second temperature threshold.

[0089] The dry burning judgment module 4 is configured to judge that a dry burning occurs when the temperature collected by the temperature sensor is greater than or equal to the current temperature threshold.

[0090] In this embodiment, vibration data can be collected by the vibration sensor on the stove or spatula, and the vibration data within the first preset time period can be used to determine whether the cooking mode is in progress. The current temperature threshold can also be adjusted in time. When the user is in different cooking modes, different temperature thresholds correspond to different cooking modes, which can effectively prevent misjudgment of turning off the fire and more intelligently determine whether dry burning occurs, thereby improving the user's cooking experience.
