Technical Field
[0001] This application relates to the field of kitchenware and cooking technology, and in particular to a method, device, equipment and storage medium for preventing dry burning. Background Technology
[0002] In cooking scenarios, anti-dry-burning stoves often achieve the purpose of preventing dry burning by setting an anti-dry-burning threshold. However, since the anti-dry-burning threshold in existing technologies is often a fixed value, it cannot meet the diverse application scenarios of cooking. That is, when anti-dry-burning is required to turn off the stove, there is no stove shut-off control, causing the food in the pot to burn; when anti-dry-burning is not required to turn off the stove, dry-burning protection is activated, which leads to misjudgment and low accuracy of anti-interference, seriously affecting the user experience. Summary of the Invention
[0003] To address the aforementioned technical problems, this application provides a technical solution for an anti-dry-burning control method, device, computer equipment, and storage medium. Specifically, this application determines the target pot-sitting state data corresponding to the target pot on the target stove based on the correspondence between thermocouple electromotive force, gear data, and preset data. Based on this target pot-sitting state data, a target anti-dry-burning threshold is determined for the target stove. Furthermore, anti-dry-burning control is applied to the target stove according to this threshold. By implementing the target anti-dry-burning threshold corresponding to different target pot-sitting state data, misjudgments in anti-dry-burning control can be avoided, achieving precise anti-dry-burning control and improving the user experience.
[0004] On one hand, embodiments of this application provide a method for preventing dry burning, the method comprising:
[0005] Obtain the thermocouple electromotive force corresponding to the target stove, as well as the gear data corresponding to the target stove;
[0006] Based on the thermocouple electromotive force, the gear position data, and the preset data correspondence, the target pot sitting state data corresponding to the target pot on the target stove is determined; the preset data correspondence characterizes the correspondence between the thermocouple electromotive force, the gear position data, and the pot sitting state data; the target pot sitting state data characterizes the state data of the target pot when it is placed on the heating surface of the target stove and the anti-dry burning probe in the target stove is moved a preset distance.
[0007] Based on the target pot sitting status data, determine the target anti-dry burning threshold corresponding to the target stove;
[0008] Based on the target anti-dry-burning threshold, the target stove is subjected to anti-dry-burning control.
[0009] Furthermore, the target pot-sitting state data includes first pot-sitting state data, second pot-sitting state data, third pot-sitting state data, and fourth pot-sitting state data. The first pot-sitting state data, the second pot-sitting state data, the third pot-sitting state data, and the fourth pot-sitting state data respectively characterize the state data when the target pot is placed on the heating surface of the target stove and the anti-dry-burning probe moves a first distance, a second distance, a third distance, and a fourth distance. The first distance is greater than the second distance, the second distance is greater than the third distance, and the third distance is greater than the fourth distance.
[0010] Accordingly, determining the target anti-dry-burning threshold for the target stove based on the target pot-sitting state data includes:
[0011] When the target pot sitting status data is the first pot sitting status data, the target anti-dry burning threshold corresponding to the target stove is determined to be the first anti-dry burning threshold.

[0018] Based on the continuous multiple electromotive forces, the environmental state data of the target stove is determined;
[0019] When the environmental state data indicates that the environmental state is stable, the thermocouple electromotive force corresponding to the target stove is determined based on the continuous multiple electromotive forces.
[0020] Further, determining the environmental state data of the target stove based on the continuous multiple electromotive forces includes...
[0021] Based on the consecutive electromotive forces, determine the standard deviation values corresponding to the consecutive electromotive forces;
[0022] Based on the standard deviation value, the environmental state data of the target stove is determined.
[0023] Further, determining the environmental state data of the target stove based on the standard deviation value includes:
[0024] If the standard deviation value is less than or equal to a preset standard deviation threshold, the environmental state data of the target stove is determined as the first state data, and the first state data indicates that the environmental state of the target stove is stable.
[0025] If the standard deviation value is greater than the preset standard deviation threshold, the environmental state data of the target stove is determined as the second state data, and the first state data indicates that the environmental state of the target stove is unstable.
[0026] Further, the step of determining the thermocouple electromotive force corresponding to the target stove based on the consecutive electromotive forces when the environmental state data indicates that the environmental state is stable includes:
[0027] When the environmental state data indicates that the environmental state is stable, a weighted average value corresponding to the consecutive electromotive forces is determined based on the consecutive electromotive forces.
[0028] The weighted average value corresponding to the consecutive multiple electromotive forces is determined as the thermocouple electromotive force corresponding to the target stove.
[0029] Furthermore, the method also includes:
[0030] When the environmental state data indicates that the environmental state is unstable, the historical thermocouple electromotive force corresponding to the target stove is obtained. The historical thermocouple electromotive force represents the thermocouple electromotive force recorded in the target stove when the target pot is placed on the heating surface of the target stove.
[0031] The historical thermocouple electromotive force is determined as the thermocouple electromotive force corresponding to the target stove.
[0032] On the other hand, embodiments of this application provide an anti-dry-burning control device, the device comprising:
[0033] The acquisition module is used to acquire the thermocouple electromotive force corresponding to the target stove, as well as the gear data corresponding to the target stove;
[0034] The target pot-sitting state data determination module is used to determine the target pot-sitting state data corresponding to the target pot on the target stove based on the thermocouple electromotive force, the gear position data, and the preset data correspondence. The preset data correspondence represents the correspondence between the thermocouple electromotive force, the gear position data, and the pot-sitting state data. The target pot-sitting state data represents the state data of the target pot when it is placed on the heating surface of the target stove and the anti-dry-burning probe in the target stove is moved a preset distance.
[0035] The target anti-dry-burning threshold determination module is used to determine the target anti-dry-burning threshold corresponding to the target stove based on the target pot sitting status data;

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0055] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0056] Please see Figure 1 The diagram shown is a flowchart illustrating an anti-dry-burning control method provided in an embodiment of this application. The following is a summary of the process. Figure 1 The technical solution of this application is described in detail. It should be noted that this specification provides the method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only execution order. The method specifically includes the following steps:
[0057] S101: Obtain the thermocouple electromotive force corresponding to the target stove, as well as the gear data corresponding to the target stove.
[0058] In this embodiment, the target stove is a gas stove. The electromotive force of the thermocouple corresponding to the target stove is determined based on the electromotive force generated by the thermocouple. The thermocouple is installed on the target stove to measure the flame temperature and generate an electromotive force corresponding to the flame temperature based on the flame temperature detected by the thermocouple endpoint. The flame temperature at the thermocouple endpoint can be measured through the thermocouple endpoint, and an electromotive force corresponding to the measured flame temperature is generated. The gear data corresponding to the target stove is the current firepower level of the target stove. Different firepower levels correspond to different heat outputs. That is, the higher the firepower level, the larger the flame output of the target stove and the higher the heat output.
[0059] In one specific implementation, such as Figure 2 As shown, it is a flowchart illustrating the thermocouple electromotive force determination method provided in this application embodiment. Specifically, step S101 includes:
[0060] S1011: Obtain multiple consecutive electromotive forces detected by the thermocouple within a preset time period;
[0061] S1012: Determine the environmental state data of the target stove based on multiple consecutive electromotive forces;
[0062] S1013: When the environmental condition data indicates that the environmental condition is stable, determine the thermocouple electromotive force corresponding to the target stove based on multiple consecutive electromotive forces.
[0063] In this embodiment of the application, the environmental state data of the target stove is determined by detecting multiple consecutive electromotive forces within a preset time period by a thermocouple. This allows for the determination of whether the environment in which the target stove is located is stable based on the environmental state data. Furthermore, different thermocouple electromotive force determination methods can be selected based on the environmental state data of the target stove, thereby eliminating interference from the environment in which the target stove is located on the determination of the thermocouple electromotive force and improving the accuracy of the thermocouple electromotive force.
[0064] In one specific embodiment, when the environmental state data indicates that the environmental state is stable, it means that there is no natural wind or other factors around the target stove that affect the flame of the stove or the continuous floating of the flame. This can avoid the situation where the accuracy of the obtained thermocouple electromotive force is low due to the interference of the environment in which the target stove is located on the flame. Specifically, when the environmental state data indicates that the environmental state is stable, the thermocouple electromotive force corresponding to the target stove can be determined based on multiple consecutive electromotive forces, thereby improving the accuracy of the thermocouple electromotive force.
[0065] In one specific implementation, such as Figure 3 As shown, it is a flowchart illustrating the environmental state data determination method provided in this application embodiment. Specifically, step S1012 includes:
[0066] S10121: Determine the standard deviation value corresponding to a series of consecutive electromotive forces.
[0067] S10122: Determine the environmental status data of the target stove based on the standard deviation value.
[0068] In this embodiment of the application, the standard deviation values corresponding to multiple consecutive electromotive forces can measure the degree of dispersion of the multiple consecutive electromotive forces. Then, based on the standard deviation values corresponding to multiple consecutive electromotive forces, the environmental state data of the target stove can be determined, so as to determine whether the environment of the target stove is stable in the current time period, so as to eliminate the interference of the environment of the target stove on the determination of the thermocouple electromotive force.
[0069] In one specific implementation, step S10122 includes:
[0070] S101221: When the standard deviation value is less than or equal to the preset standard deviation threshold, the environmental state data of the target stove is determined as the first state data, and the first state data indicates that the environmental state of the target stove is stable.
[0071] S101222: When the standard deviation value is greater than the preset standard deviation threshold, the environmental state data of the target stove is determined as the second state data, and the first state data indicates that the environmental state of the target stove is unstable.
[0072] In this embodiment, when the standard deviation is less than or equal to a preset standard deviation threshold, it indicates that there is no natural wind or other factors affecting the flame's continuous movement around the target stove. Therefore, there is no factor affecting the thermocouple's accurate detection of the flame temperature, and a more accurate thermocouple electromotive force can be determined. When the standard deviation is greater than the preset standard deviation threshold, it indicates that there is natural wind or other factors affecting the flame's continuous movement around the target stove. Therefore, the electromotive force detected by the thermocouple under the current environment cannot be used to determine the thermocouple electromotive force, mainly because the thermocouple's... The endpoint position remains constant, but the flame is constantly drifting due to natural winds or other factors affecting the flame's continuous movement around the target stove. Consequently, the position of the thermocouple tip within the flame also changes. Since different parts of the flame have different temperatures—lower in the inner flame and higher in the outer flame, with the outermost edge being the hottest—it's not possible to use multiple electromotive forces detected by the thermocouple under the current environment to determine the thermocouple's electromotive force. This avoids interference from the target stove's environment in determining the thermocouple's electromotive force, improving the accuracy of anti-dry-burning measures.
[0073] In one specific implementation, such as Figure 4 As shown, it is a flowchart illustrating a specific method for determining the electromotive force of a thermocouple provided in an embodiment of this application. Specifically, step S1013 includes:
[0074] S10131: When environmental state data indicates that the environmental state is stable, determine the weighted average value corresponding to multiple consecutive electromotive forces based on multiple consecutive electromotive forces.
[0075] S10132: The weighted average value of multiple consecutive electromotive forces is determined as the thermocouple electromotive force corresponding to the target stove.
[0076] In this embodiment of the application, the weighted average value corresponding to multiple consecutive electromotive forces is determined as the thermocouple electromotive force corresponding to the target stove, so as to avoid the deviation of the individual electromotive force detected by the thermocouple, which would lead to inaccurate thermocouple electromotive force, thereby improving the accuracy of anti-dry burning.
[0077] In one specific implementation, the method further includes:
[0078] S1014: When the environmental state data indicates that the environmental state is unstable, obtain the historical thermocouple electromotive force corresponding to the target stove. The historical thermocouple electromotive force represents the thermocouple electromotive force recorded in the target stove when the target pot is placed on the heating surface of the target stove.
[0079] S1015: Determine the historical thermocouple electromotive force as the thermocouple electromotive force corresponding to the target stove.
[0080] In this embodiment, when environmental state data indicates an unstable environment, it suggests the presence of natural winds or other factors affecting the flame's continuous movement around the target stove. This allows for the acquisition of the historical thermocouple electromotive force (EMF) corresponding to the target stove. The historical EMF characterizes the EMF recorded when the target pot is placed on the stove's heating surface. In some specific embodiments, the historical EMF includes the EMF corresponding to the target pot at various power levels. Therefore, when environmental state data indicates an unstable environment, the historical EMF is determined as the EMF corresponding to the target stove. This, combined with the currently acquired power level data, yields the EMF corresponding to the target stove under the current target pot condition. This avoids low accuracy of the obtained EMF due to interference from the target stove's environment, thus improving the accuracy of the EMF.
[0081] S102: Based on the correspondence between thermocouple electromotive force, gear position data and preset data, determine the target pot sitting state data corresponding to the target pot on the target stove; the preset data correspondence characterizes the correspondence between thermocouple electromotive force and gear position data and pot sitting state data; the target pot sitting state data characterizes the state data when the target pot is placed on the heating surface of the target stove and the anti-dry burning probe in the target stove moves a preset distance.
[0082] In this embodiment of the application, the anti-dry-burn probe in the target stove can move up and down. Specifically, when the target pot is placed on the target stove, the anti-dry-burn probe moves downward due to the pressure of the target pot. When the target pot is removed from the target stove, the anti-dry-burn probe is relieved of the pressure of the target pot and moves upward. The anti-dry-burn probe is used to detect the temperature of the bottom of the pot.
[0083] It should be noted that when the target cookware is placed on the target stove and the target stove is turned on, the target cookware will compress the stove flame, causing the flame to spread out. Specifically, for the same setting, the greater the distance the target cookware compresses the anti-dry-burn probe in the target stove by moving the preset distance, the greater the degree of flame spreading; conversely, the smaller the distance the target cookware compresses the anti-dry-burn probe in the target stove by moving the preset distance, the smaller the degree of flame spreading. Since the position of the thermocouple endpoints remains constant, and the inner flame temperature is low while the outer flame temperature is high, with the outermost edge of the outer flame having the highest temperature, for the same setting, when the flame is at different degrees of spreading, the thermocouple electromotive force corresponding to the flame temperature at the current degree of spreading can be obtained.
[0084] For example, for the same set of data, compared to a target cookware with a flat bottom, the target cookware with a downwardly convex bottom, when placed on the target stove, causes the anti-dry-burn probe to move a greater distance than the target cookware with a flat bottom. Therefore, the target cookware with a downwardly convex bottom causes the flame to spread more widely than the target cookware with a flat bottom. If, when the target cookware with a downwardly convex bottom is placed on the target stove, the thermocouple can detect the temperature of the outer flame, then when the target cookware with a downwardly convex bottom is placed on the target stove... When a target cookware with a flat bottom is placed on a target stove, the thermocouple can only detect the temperature of the flame inside the outer flame. Specifically, the thermocouple can detect the temperature of the flame between the outer and inner flames, or the temperature of the inner flame. Since the inner flame has a lower temperature and the outer flame has a higher temperature, with the outermost edge of the outer flame being the hottest, for the same setting, the distance the anti-dry-burn probe in the target stove moves when the target cookware is pressed against it will vary under different thermocouple electromotive forces. Therefore, by determining the thermocouple electromotive force, the target cookware's corresponding pot-sitting state data can be determined.
[0085] In some embodiments, for the same target cooktop, the thermocouple electromotive force corresponding to the target cooktop is different under different gear data. Specifically, the higher the gear corresponding to the gear data, the longer the corresponding flame. For a fixed thermocouple, the thermocouple electromotive force corresponding to the different gear data is different. Thus, when the thermocouple electromotive force and gear data are determined, the target pot sitting state data corresponding to the target cooktop can be determined in reverse.
[0086] In one specific embodiment, the preset data correspondence represents the correspondence between the thermocouple electromotive force and gear position data and the pot sitting state data. It can be obtained through a large number of test experiments. Under the premise that the thermocouple electromotive force and gear position data are determined, the target pot sitting state data corresponding to the target pot on the target stove can be determined based on the thermocouple electromotive force, gear position data and preset data correspondence. In order to determine the target anti-dry burning threshold of the target stove corresponding to the target pot sitting state data, the automatic adjustment of the target anti-dry burning threshold can be realized, thereby improving the accuracy of anti-dry burning.
[0087] S103: Determine the target anti-dry-burning threshold corresponding to the target stove based on the target pot status data.
[0088] S104: Control the target stove to prevent dry burning based on the target dry burning threshold.
[0089] In this embodiment, the target anti-dry-burning threshold corresponding to the target stove can be determined based on the target pot sitting status data. Then, the target stove can be controlled to prevent dry burning based on the target anti-dry-burning threshold. This allows for the implementation of the target anti-dry-burning threshold corresponding to different target pot sitting status data, thereby avoiding misjudgments in anti-dry-burning control, achieving precise control of anti-dry burning, and improving the user experience.
[0090] In an optional implementation, the target pot-sitting state data includes first pot-sitting state data, second pot-sitting state data, third pot-sitting state data, and fourth pot-sitting state data. These data respectively characterize the state of the target pot when it is placed on the heating surface of the target stove and the anti-dry-burning probe is moved a first distance, a second distance, a third distance, and a fourth distance, respectively. The first distance is greater than the second distance, the second distance is greater than the third distance, and the third distance is greater than the fourth distance. Figure 5 As shown, it is a flowchart illustrating a method for determining a target anti-dry-burning threshold provided in an embodiment of this application. Accordingly, step S103 includes:
[0091] S1031: When the target pot sitting status data is the first pot sitting status data, the target anti-dry burning threshold corresponding to the target stove is determined to be the first anti-dry burning threshold.
[0092] S1032: When the target pot sitting status data is the second pot sitting status data, the target anti-dry burning threshold corresponding to the target stove is determined to be the second anti-dry burning threshold.
[0093] S1033: When the target pot sitting status data is the third pot sitting status data, the target anti-dry burning threshold corresponding to the target stove is determined to be the third anti-dry burning threshold.
[0094] S1034: When the target pot sitting status data is the fourth pot sitting status data, the target anti-dry burning threshold corresponding to the target stove is determined to be the fourth anti-dry burning threshold; wherein, the first anti-dry burning threshold is less than the second anti-dry burning threshold, the second anti-dry burning threshold is less than the third anti-dry burning threshold, and the third anti-dry burning threshold is less than the fourth anti-dry burning threshold.
[0095] In this embodiment, the target cooktop corresponding to the first pot-sitting state data can be a pot with a downwardly convex bottom. When the pot with the downwardly convex bottom is placed on the heating surface of the target cooktop, the anti-dry-burning probe can be moved a first distance by squeezing it. The target cooktop corresponding to the second pot-sitting state data can be a pot with a flat bottom. When the pot with the flat bottom is placed on the heating surface of the target cooktop, the anti-dry-burning probe can be moved a second distance by squeezing it. The target cooktop corresponding to the third pot-sitting state data can be a pot with an upwardly concave bottom. When the pot with the upwardly concave bottom is placed on the heating surface of the target cooktop, the anti-dry-burning probe can be moved a third distance by squeezing it. The fourth pot-sitting state data can be state data where the target pot is not on the target cooktop. In this case, the distance moved by squeezing the anti-dry-burning probe can be considered to be zero, that is, the fourth distance is zero.
[0096] Furthermore, when the target pot-sitting state data is determined to be the first pot-sitting state data, it indicates that the target cookware placed on the target stove has a downwardly convex bottom, and thus the target anti-dry-burning threshold corresponding to the target cookware can be determined to be the first anti-dry-burning threshold. When the target pot-sitting state data is determined to be the second pot-sitting state data, it indicates that the target cookware placed on the target stove has a flat bottom, and thus the target anti-dry-burning threshold corresponding to the target cookware can be determined to be the second anti-dry-burning threshold. When the target pot-sitting state data is determined to be the third pot-sitting state data, it indicates that the target cookware placed on the target stove has an upwardly concave bottom, and thus the target anti-dry-burning threshold corresponding to the target cookware can be determined to be the third anti-dry-burning threshold. The anti-dry-burn threshold is the third anti-dry-burn threshold. When the target pot-sitting state data is determined to be the fourth pot-sitting state data, it indicates that no target pot is placed on the target stove. Therefore, the target anti-dry-burn threshold corresponding to the target stove can be determined to be the fourth anti-dry-burn threshold. The first anti-dry-burn threshold is less than the second anti-dry-burn threshold, the second anti-dry-burn threshold is less than the third anti-dry-burn threshold, and the third anti-dry-burn threshold is less than the fourth anti-dry-burn threshold. That is, the greater the distance that the anti-dry-burn probe moves when the target pot is placed on the heating surface of the target stove, the smaller its corresponding anti-dry-burn threshold is. This allows for different target anti-dry-burn thresholds to be applied to different target stoves, thereby improving the anti-dry-burn accuracy and avoiding misjudgment.
[0097] In practical applications, the first anti-dry-burning threshold is less than the second anti-dry-burning threshold, which is less than the third anti-dry-burning threshold, which is less than the fourth anti-dry-burning threshold. The specific values can be obtained through experiments and are not specifically limited here.
[0098] In one specific embodiment, the target anti-dry-burning threshold corresponding to the target stove can be set as the corresponding anti-dry-burning threshold according to the different depths of the downward protrusion of the target pot with the downward protruding bottom, so as to achieve precise anti-dry-burning control. Alternatively, the target anti-dry-burning threshold corresponding to the target stove can be set as the corresponding anti-dry-burning threshold according to the different depths of the upward concavity of the target pot with the upward concave bottom, so as to achieve precise anti-dry-burning control.
[0099] As can be seen from the above technical solutions of the embodiments of this application, the following technical effects are achieved:
[0100] This application determines the target pot-sitting state data corresponding to the target pot on the target stove based on the correspondence between thermocouple electromotive force, gear data, and preset data. In order to determine the target anti-dry-burning threshold corresponding to the target stove based on the target pot-sitting state data, the target stove can be controlled to prevent dry burning based on the target anti-dry-burning threshold.
