Description

Gas stove control methods and gas stove Technical Field

[0001] This application relates to the field of gas stove technology, and in particular to a control method for a gas stove and a gas stove. Background Technology

[0002] As a commonly used cooking appliance, the safety performance of gas stoves is receiving increasing attention. One major concern is that prolonged dry-burning of pots on a gas stove can cause serious safety issues. Anti-dry-burning technology can enhance the safety of gas stoves. However, in existing non-contact anti-dry-burning technologies, when the user actively adjusts the gas stove's heat (especially quickly switching from low to high), the temperature detected by the temperature sensor rises rapidly within a short period. The shape of this temperature rise curve closely resembles the temperature change characteristics of a pot in the initial stage of dry-burning. This similar signal characteristic can easily cause the control system to have difficulty accurately distinguishing between normal heat adjustment and actual dry-burning, leading to misjudgments by the anti-dry-burning function, resulting in the gas stove unexpectedly shutting off and interfering with the cooking process. Summary of the Invention

[0003] This application provides a control method for a gas stove and a gas stove, so as to improve the accuracy of judging the dry burning state of the gas stove and improve the user experience.

[0004] To address the aforementioned technical problems, this application provides a control method for a gas stove. The control method includes: in response to the gas stove being in a dry-burning state, determining whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information; in response to the gas stove being in a firepower adjustment state, adjusting the gas stove's dry-burning judgment strategy; and in response to the gas stove not being in a firepower adjustment state, controlling the gas stove to stop working.

[0005] In one embodiment, in response to the gas stove being in a firepower adjustment state, adjusting the dry burning judgment strategy of the gas stove includes: in response to the gas stove being in a firepower adjustment state, adjusting the first dry burning judgment condition corresponding to the dry burning state to a second dry burning judgment condition; the temperature parameter threshold corresponding to the first dry burning judgment condition is less than the temperature parameter threshold corresponding to the second dry burning judgment condition.

[0006] In one embodiment, in response to the gas stove being in a firepower adjustment state, the dry burning determination strategy of the gas stove is adjusted, including: in response to the gas stove being in a firepower adjustment state, the determination of the dry burning state is stopped.

[0007] In one embodiment, the control method further includes: after the gas stove operates for a preset time with the adjusted dry-burning judgment strategy, restoring the gas stove's dry-burning judgment strategy to the original strategy.

[0008] In one embodiment, the firepower adjustment information includes the adjustment direction. In response to the gas stove being in a dry-burning state, determining whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information includes: in response to the gas stove being in a dry-burning state, determining whether the adjustment direction is positive adjustment; and in response to the adjustment direction being positive adjustment, determining that the gas stove is in a firepower adjustment state.

[0009] In one embodiment, the firepower adjustment information includes flame power. In response to the gas stove being in a dry-burning state, determining whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information includes: in response to the gas stove being in a dry-burning state, determining whether the current flame power is greater than the flame power at the previous moment; and in response to the current flame power being greater than a preset power, determining that the gas stove is in a firepower adjustment state.

[0010] In one embodiment, before the step of determining whether the gas stove is in a firepower adjustment state based on the firepower adjustment information of the gas stove in response to the gas stove being in a dry-burning state, the control method further includes: acquiring the temperature sensing information of the gas stove and the firepower adjustment information of the gas stove; and determining that the gas stove is in a dry-burning state in response to the temperature sensing information meeting the first dry-burning determination condition.

[0011] In one embodiment, the temperature sensing information includes first temperature sensing information and second temperature sensing information, and the first dry burning determination condition includes a first preset condition and a second preset condition. Responding to the temperature sensing information meeting the first dry burning determination condition, determining that the gas stove is in a dry burning state includes: responding to the first temperature sensing information meeting the first preset condition and the second temperature sensing information meeting the second preset condition, then determining that the gas stove is in a dry burning state; responding to the first temperature sensing information not meeting the first preset condition or the second temperature sensing information not meeting the second preset condition, determining that the gas stove is in a non-dry burning state.

[0012] To solve the above-mentioned technical problems, this application provides a gas stove, which includes: a body; a temperature sensing component disposed on the body, the temperature sensing component being configured to collect temperature sensing information of the gas stove; and a controller connected to the temperature sensing component, the controller executing the control method of any one of the above-mentioned methods based on the temperature sensing information and the firepower adjustment information of the gas stove.

[0013] In one embodiment, the gas stove further includes a firepower detection component connected to the controller, the firepower detection component being configured to collect firepower adjustment information.

[0014] The beneficial effects of this application are as follows: When the gas stove is in a dry-burning state, the control method further determines whether the gas stove is in a flame adjustment state based on the gas stove's flame adjustment information. If the gas stove is in a flame adjustment state, the dry-burning judgment strategy is adjusted to prevent the gas stove from directly triggering the dry-burning protection and allow it to continue working normally. If the gas stove is not in a flame adjustment state, the gas stove is controlled to stop working. This control method reduces the interference of flame adjustment state on the dry-burning state judgment, thereby improving the accuracy of dry-burning state judgment, enhancing the safety of the gas stove, and improving the user experience.

[0032] As a commonly used cooking appliance, the safety performance of gas stoves is receiving increasing attention. One major concern is that prolonged dry-burning of pots on a gas stove can cause serious safety issues, and anti-dry-burning technology can enhance the safety of gas stoves. However, existing anti-dry-burning technologies have poor anti-interference capabilities and low accuracy in judging the pot's dry-burning status, failing to meet users' dual needs for safety and user experience. For example, in existing non-contact anti-dry-burning technologies, when users actively adjust the gas stove's heat (especially quickly switching from low to high), the temperature detected by the temperature sensor rises rapidly in a short period, and the shape of its temperature rise curve is very similar to the temperature change characteristics of a pot in the early stages of dry-burning. This similar signal characteristic can easily cause the control system to have difficulty accurately distinguishing between normal heat adjustment and actual dry-burning, leading to misjudgment of the anti-dry-burning function, causing the gas stove to shut off unexpectedly and interfering with the cooking process.

[0033] To address the aforementioned technical problems, this application provides a gas stove 10 that enhances the anti-interference capability of dry-burning state judgment and improves the accuracy of dry-burning state judgment, thereby meeting users' needs for the safety performance and user experience of the gas stove 10. Specifically, referring to Figures 1 to 3, Figure 1 is a schematic diagram of the framework of one embodiment of the gas stove provided in this application, Figure 2 is a schematic diagram of the framework of another embodiment of the gas stove provided in this application, and Figure 3 is a schematic diagram of the structure of one embodiment of the gas stove provided in this application. The gas stove 10 includes a temperature sensing component 120 and a controller 110. It can be seen that a pot (not shown) is placed on the side of the gas stove 10's body 170 facing the pot. The gas stove 10's body 170 is used to provide a flame and heat the pot placed thereon. The temperature sensing component 120 is configured to acquire temperature sensing information of the gas stove 10, wherein the temperature sensing information can be parameters directly or indirectly related to temperature, such as temperature, temperature rise rate, and temperature difference. The temperature sensing component 120 can be located on one side of the gas stove 10 body 170 near the bottom of the pot, or on the side of the gas stove 10 body 170 away from the pot; this is not limited. The controller 110 can obtain the firepower adjustment information of the gas stove 10 based on temperature, or it can obtain the firepower adjustment information through additional components; this is not limited. The firepower adjustment information refers to physical quantities or state changes that are directly or indirectly related to the firepower of the gas stove 10. For example, the firepower adjustment information can be one or more parameters such as the direction of firepower adjustment, the degree of adjustment, and the flame power of the gas stove 10; this is not limited.

[0034] In one embodiment, the gas stove 10 includes a flame detection component 130, which is configured to collect flame adjustment information of the gas stove 10. By setting the flame detection component 130 to collect flame adjustment information, the gas stove 10 in this embodiment can accelerate the acquisition speed of flame adjustment information, thereby improving the response speed of the gas stove 10.

[0035] In one embodiment, the flame detection component 130 includes a potentiometer (not shown). The potentiometer is located on the valve stem or knob shaft of the regulating valve (not shown) of the gas stove 10. When the knob is turned to adjust the flame, the resistance of the potentiometer changes continuously. The controller 110 can read the voltage of the potentiometer to know the flame opening degree and its changes in real time and accurately. In this embodiment, the flame detection component 130 includes a potentiometer, which can detect changes in the valve position of the regulating valve. Based on the changes in the valve position, information such as whether the flame of the gas stove 10 is increased, remains unchanged, or decreases can be obtained.

[0036] In one embodiment, the firepower detection component 130 includes a Hall effect sensor component (not shown), which includes a magnet and a Hall sensor. The magnet is mounted on the valve stem, and the Hall sensor is positioned at a corresponding location on the magnet. When the knob is rotated, the Hall sensor generates a pulse signal. By counting the pulses (switch type) or parsing the code (encoder type), the rotation angle, direction, and speed of the knob can be accurately identified. Based on the rotation angle, direction, and speed, information such as whether the gas stove 10 has increased firepower, remained unchanged, or decreased firepower can be determined.

[0037] In one embodiment, the fire detection component 130 includes a flame state sensor (not shown), such as an ion flame probe, an optical sensor, or other sensors. The flame state sensor monitors the characteristics of the flame itself to infer changes in fire intensity.

[0038] In one embodiment, the temperature sensing component 120 includes a first temperature sensing element 121, which is disposed on the side of the gas stove body 170 facing the pot to collect first temperature information of the bottom of the pot. This arrangement improves the accuracy of pot temperature detection compared to placing the element within the body 170. The first temperature sensing element 121 is mainly used to collect first temperature information of the bottom of the pot. This first temperature information can be one or more parameters such as a first temperature corresponding to the bottom of the pot, a first temperature rise rate, and a first temperature-related difference, which are not limited here. Specifically, the top of the first temperature sensing element 121 does not exceed the top of the inner ring burner cap (not shown in the figure) and / or the outer ring burner cap (not shown in the figure) of the stove 180, so that the first temperature sensing element 121 does not contact the bottom of the pot. This reduces the probability of mechanical damage to the first temperature sensing element 121 and increases its service life. Furthermore, the non-contact temperature measurement method can reduce dirt on the first temperature sensing element 121, thereby improving the accuracy of temperature measurement by the first temperature sensing element 121. In addition, to alleviate the low accuracy of dry-burning state judgment caused by the non-contact temperature measurement method, this application, in response to the gas stove 10 being in a dry-burning state, further confirms whether the gas stove 10 is in a flame adjustment state (i.e., a flame increased state). When the gas stove 10 is in a flame adjustment state, the dry-burning judgment strategy of the gas stove is adjusted so that the gas stove will not directly trigger the dry-burning protection and can continue to work normally. When the gas stove 10 is not in a flame adjustment state, the gas stove 10 is controlled to stop working. Through the above control method, the interference of the flame adjustment state on the dry-burning state judgment can be reduced, thereby improving the accuracy of dry-burning state judgment, enhancing the safety of the gas stove, and improving the user experience.

[0039] In one embodiment, the temperature sensing component 120 further includes a second temperature sensing element 122. The second temperature sensing element 122 is disposed within the body 170 of the gas stove 10 to collect second temperature information of the body 170 of the gas stove 10. Specifically, the second temperature sensing element 122 is located in the internal region of the stove body below the panel of the body 170. This region can isolate external airflow, collisions, and other environmental interference, and stably collect the temperature of the body 170 of the gas stove 10. The second temperature information can be one or more of the following parameters: a second temperature corresponding to the body 170, a second temperature rise rate, a second temperature-related difference, etc., and is not limited herein. In this embodiment, the gas stove 10 has a first temperature sensing element 121 and a second temperature sensing element 122 respectively installed on the bottom side of the gas stove 10 body 170 facing the pot and inside the gas stove 10 body 170. This allows the gas stove 10 to determine whether it is in a dry-burning state by sensing the temperature information from two different locations. This avoids misjudgment caused by interference from the temperature sensing information collected from the bottom of the pot, enhances anti-interference ability and improves the accuracy of judgment, thereby improving the user experience.

[0040] In one embodiment, the gas stove 10 further includes a prompting component 140, configured to output prompting information. This prompting information can also be understood as a warning message. When the gas stove 10 detects that the pot is in a dry-burning state, the prompting component 140 can output prompting information to warn the user. The prompting information can be sound, light, text, graphics, vibration, etc., and can be one or more types, without limitation. Correspondingly, the prompting component 140 can include one or more circuits such as a display circuit, a buzzer, a speaker, and a vibration circuit, without limitation. The display circuit can be an OLED display circuit, a liquid crystal display circuit, a digital tube display circuit, etc., without limitation.

[0041] In one embodiment, the gas stove 10 further includes a first switch assembly 150, which can be used to turn the anti-dry-burning function of the gas stove 10 on or off to meet the user's needs for cooking methods such as dry-frying. The gas stove 10 also includes a second switch assembly 160, which can also be used to control the gas stove 10 to delay shutting off when in a dry-burning state, to meet the user's needs for cooking methods such as dry-frying and to free up their hands.

[0042] In one embodiment, the gas stove 10 includes at least one burner 180. When the gas stove 10 includes two or more burners 180, all burners 180 may have an anti-dry-burning function. Alternatively, one burner may have an anti-dry-burning function while the other does not, to meet the user's needs for cooking methods such as dry pot cooking.

[0043] To address the aforementioned technical problems, this application provides a control method for the aforementioned gas stove. The gas stove is the executing entity of this control method. Referring to Figure 4, the control method includes:

[0044] Step S110: In response to the gas stove being in a dry-burning state, determine whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information.

[0045] Existing dry-burning detection technologies primarily rely on temperature sensing information from the pot or gas stove to determine whether the gas stove or pot is in a dry-burning state. However, when the gas stove's temperature sensing information is obtained through non-contact measurement, the pot's temperature, temperature difference, or temperature rise rate can change drastically over a period after the gas stove's heat is increased. The characteristics of these changed parameters are similar to those observed during the initial dry-burning stage, leading to misjudgments of the dry-burning state. To improve the accuracy of dry-burning state detection, this application determines whether the gas stove is in a heat adjustment state based on heat adjustment information when the gas stove or pot is in a dry-burning state.

[0046] The firepower adjustment information refers to physical quantities or state changes directly or indirectly related to the firepower of the gas stove. For example, firepower adjustment information can be one or more parameters such as the real-time temperature, adjustment direction, adjustment level, and flame power of the gas stove. In this application, the firepower adjustment state refers to the state where the gas stove's firepower is adjusted from low to high. Firepower adjustment information can be obtained based on the temperature of the pot. For example, after the gas stove detects a rapid temperature rise, it continuously tracks the temperature change over a period of time. If the temperature stabilizes after the rapid rise, it is determined to be in a firepower adjustment state. Alternatively, firepower adjustment information can be obtained through a firepower detection component. Firepower adjustment information can be one or more of flame power and adjustment direction, and is not limited here.

[0047] Step S120: In response to the gas stove being in the firepower adjustment state, adjust the dry burning judgment strategy of the gas stove.

[0048] In response to the gas stove being in the heat adjustment state, i.e. the current gas stove dry-burn judgment strategy is misjudged by the controller due to the interference of the gas stove being in the heat adjustment state, in order to avoid the gas stove triggering the dry-burn protection due to misjudgment and affecting the normal cooking of food, this application adjusts the gas stove's dry-burn judgment strategy when the gas stove is in the heat adjustment state, so that the gas stove can continue to work and the food can continue to be cooked.

[0049] Step S130: In response to the gas stove not being in flame adjustment mode, control the gas stove to stop working.

[0050] When the gas stove is not in flame adjustment mode, the dry-burning state eliminates interference from flame adjustment and confirms that the gas stove or the pot is currently in a dry-burning state. To avoid serious safety accidents, the gas stove is controlled to stop working. Controlling the gas stove to stop working means controlling the gas stove to stop heating the pot. Specifically, stopping the gas stove from heating the pot can be achieved by turning off the gas stove's switch, which stops the gas supply to the stove's burner; or by closing the gas passage, which is not limited to this. Controlling the gas stove to stop working can be done immediately; after a preset time; after a preset time and without detected user intervention; or after a preset time and without updated information indicating that the gas stove has been removed from the dry-burning state, which is not limited to this.

[0051] The control method of this application, when the gas stove is in a dry-burning state, further determines whether the gas stove is in a flame adjustment state based on the gas stove's flame adjustment information. If the gas stove is in a flame adjustment state, the dry-burning judgment strategy is adjusted to prevent the gas stove from directly triggering the dry-burning protection and allow it to continue working normally. If the gas stove is not in a flame adjustment state, the gas stove is controlled to stop working. This control method reduces the interference of flame adjustment state on dry-burning state judgment, thereby improving the accuracy of dry-burning state judgment, enhancing gas stove safety, and improving the user experience.

[0052] In one embodiment, step S120, in response to the gas stove being in a flame adjustment state, adjusts the gas stove's dry-burning judgment strategy, including the following steps:

[0053] Step S121: In response to the gas stove being in the firepower adjustment state, the first dry burning judgment condition corresponding to the dry burning state is adjusted to the second dry burning judgment condition.

[0054] When the gas stove is in flame adjustment mode, the increased flame causes the temperature, temperature difference, and temperature rise rate of the gas stove or pot to be similar to or the same as those parameters when the pot is in a dry-burning state. To prevent the gas stove from triggering its dry-burning protection and to allow it to continue operating normally, the first dry-burning judgment condition is adjusted to a second dry-burning judgment condition. The temperature parameter threshold corresponding to the first dry-burning judgment condition is lower than the temperature parameter threshold corresponding to the second dry-burning judgment condition. The temperature parameter threshold can be one or more of the following: temperature threshold, temperature difference threshold, and temperature rise rate threshold; there are no restrictions here. The first dry-burning judgment condition is the condition for the gas stove to determine a normal dry-burning state, and the second judgment condition is the condition for the gas stove to prevent the dry-burning protection setting from being triggered.

[0055] This application allows the gas stove to continue working normally by adjusting the first dry burning judgment condition corresponding to the dry burning state to the second dry burning judgment condition when the gas stove is in the firepower adjustment state. This adjustment method is simple, easy to implement and has a fast response speed, which can improve the user experience and the safety performance of the gas stove.

[0056] In one embodiment, step S120, in response to the gas stove being in a flame adjustment state, adjusts the gas stove's dry-burning determination strategy, including the following steps:

[0057] Step S221: In response to the gas stove being in flame adjustment mode, the determination of dry burning state is stopped.

[0058] When the gas stove is in the power adjustment mode, the increased power causes the temperature, temperature difference, and temperature rise rate of the gas stove or pot to be similar to or the same as the temperature, temperature difference, and temperature rise rate when the pot is in a dry-burning state. In order to prevent the gas stove from triggering the dry-burning protection and to allow the gas stove to continue to work normally, the gas stove stops judging the dry-burning state.

[0059] This application allows the gas stove to continue working normally by stopping the determination of dry burning when the gas stove is in the firepower adjustment state. This adjustment method is simple, easy to implement and has a fast response speed, which can improve the safety performance of the gas stove.

[0060] In one embodiment, the firepower adjustment information includes the adjustment direction. Referring to Figure 5, step S110, in response to the gas stove being in a dry-burning state, determines whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information, including the following steps:

[0061] Step S111: In response to the gas stove being in a dry-burning state, determine whether the adjustment direction is positive.

[0062] The adjustment direction refers to the adjustment direction of the gas stove's valve body. When the valve body is adjusted in the forward direction, the gas stove's flame intensity increases; when the valve body is adjusted in the reverse direction, the gas stove's flame intensity decreases; when the valve body's adjustment direction remains unchanged, the gas stove's flame intensity remains unchanged. To avoid misjudgment caused by increased flame intensity when the gas stove is in a dry-burning state, this embodiment determines whether the gas stove is in a flame intensity adjustment state by checking whether the gas stove's valve body's adjustment direction is in the forward direction.

[0063] Step S112: In response to the adjustment direction being positive, determine that the gas stove is in the firepower adjustment state.

[0064] When the adjustment direction of the gas stove's valve body is positive, it indicates that the gas stove is in the firepower adjustment state.

[0065] Step S113: In response to the adjustment direction being reversed or unchanged, determine that the gas stove is not in the firepower adjustment state.

[0066] When the adjustment direction of the gas stove's valve body is reversed or remains unchanged, it is determined that the gas stove is not in the flame adjustment state.

[0067] This embodiment determines whether the gas stove is in the flame adjustment direction by adjusting the valve body of the gas stove. This method can reduce interference and improve the accuracy of flame adjustment status judgment, thereby enhancing the safety of the gas stove.

[0068] In one embodiment, the firepower adjustment information includes flame power. Referring to Figure 6, step S110, in response to the gas stove being in a dry-burning state, determines whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information, including the following steps:

[0069] Step S211: In response to the gas stove being in a dry-burning state, determine whether the current flame power is greater than the flame power at the previous moment.

[0070] The flame power corresponds to the firepower of the gas stove; a lower flame power indicates lower firepower, and a higher flame power indicates higher firepower. When the gas stove is in a dry-burning state, it is determined whether the current flame power is greater than the flame power at the previous moment.

[0071] Step S212: In response to the current flame power being greater than the flame power at the previous moment, determine that the gas stove is in flame adjustment mode.

[0072] If the current flame power is greater than the flame power at the previous moment, then the gas stove is determined to be in flame adjustment mode.

[0073] Step S213: In response to the current flame power being less than or equal to the flame power at the previous moment, determine that the gas stove is not in flame adjustment mode.

[0074] If the current flame power is less than or equal to the flame power at the previous moment, it is determined that the gas stove is not in flame adjustment mode.

[0075] This embodiment determines whether the gas stove is in a firepower adjustment state by obtaining the flame power of the gas stove. This method is simple, easy to implement, and can improve the response rate.

[0076] In one embodiment, to achieve intelligent control of the gas stove, the control method further includes the following steps:

[0077] Step S140: After the gas stove has operated for a preset time with the adjusted dry burning judgment strategy, restore the gas stove's dry burning judgment strategy to the original strategy.

[0078] After the gas stove operates for a preset time using the adjusted dry-burning judgment strategy, the data anomalies caused by increased firepower tend to stabilize. At this point, the gas stove's dry-burning judgment strategy is restored to its original strategy to continue monitoring whether the gas stove is in a dry-burning state. This achieves intelligent monitoring of the gas stove's dry-burning state and enhances its safety performance. The original strategy refers to the gas stove's judgment strategy for determining whether the pot is in a dry-burning state. For example, the original strategy might be: whether the temperature sensing information meets the first dry-burning judgment condition; the adjusted dry-burning judgment strategy might be: whether the temperature sensing information meets the second dry-burning judgment condition, which is not limited here.

[0079] In one embodiment, referring to FIG7, before step S110, which determines whether the gas stove is in a firepower adjustment state based on the gas stove's firepower adjustment information in response to the gas stove being in a dry-burning state, the control method further includes the following steps:

[0080] Step S150: Obtain the temperature sensing information and firepower adjustment information of the gas stove.

[0081] The acquisition of temperature sensing information and firepower adjustment information can be simultaneous, or the firepower adjustment information can be acquired after a preset time interval from the acquisition of temperature sensing information; this is not limited. Specifically, the temperature sensing information of the gas stove can be collected from the bottom of the pot, or, to reduce interference, from the gas stove itself; this is not limited. The temperature sensing information can be one or more parameters such as temperature, temperature rise rate, and temperature difference; this is not limited. The firepower adjustment information can be obtained based on the pot's temperature. For example, after the system detects a rapid temperature rise, it continuously tracks the temperature change over a period of time. If the temperature stabilizes after the rapid rise, it is determined that the firepower has been adjusted. Alternatively, the firepower adjustment information can be acquired through a firepower detection component.

[0082] Step S160: In response to the temperature sensing information meeting the first dry burning determination condition, determine that the gas stove is in a dry burning state.

[0083] The temperature sensing information can be one or more parameters such as temperature, temperature rise rate, and temperature difference, and there is no restriction on this. The first dry-burning judgment condition can be one or more of the following: temperature threshold, temperature rise rate threshold, and temperature difference threshold. For example, if the temperature sensing information includes the temperature rise rate, and the temperature rise rate is greater than the temperature rise rate threshold, then the temperature sensing information meets the first dry-burning judgment condition, and the gas stove is determined to be in a dry-burning state.

[0084] In one embodiment, to improve the accuracy of determining the dry-burning state, the temperature sensing information includes first temperature sensing information and second temperature sensing information. The first dry-burning determination condition includes a first preset condition and a second preset condition. Referring to Figure 8, step S160, in response to the temperature sensing information meeting the first dry-burning determination condition, determines that the gas stove is in a dry-burning state, including the following steps:

[0085] Step S161: In response to the first temperature sensing information meeting the first preset condition and the second temperature sensing information meeting the second preset condition, it is determined that the gas stove is in a dry-burning state.

[0086] The first temperature sensor is mainly used to collect first temperature information from the bottom of the pot. This first temperature information can be directly or indirectly related to the temperature of the bottom of the pot, such as one or more parameters including the first temperature of the bottom of the pot, the first temperature rise rate, and the first temperature difference; there are no restrictions here. The second temperature sensor is located inside the gas stove body. Specifically, the second temperature sensor is located in the internal area of ​​the stove body below the panel. This area can isolate external airflow, collisions, and other environmental interference, and stably collect the temperature of the gas stove body. The second temperature information can be directly or indirectly related to the temperature of the body, such as one or more parameters including the second temperature of the body, the second temperature rise rate, and the second temperature difference; there are no restrictions here.

[0087] Since both the first and second temperature sensing information are obtained directly or calculated by collecting the temperature corresponding to the bottom of the pot and the body of the gas stove in real time, the first and second temperature sensing information can be obtained simultaneously; or the second temperature sensing information can be obtained after a preset time after the first temperature sensing information is obtained. There is no restriction here.

[0088] This application determines that the gas stove or pot is in a dry-burning state only if both the first and second temperature sensing data meet their corresponding preset conditions. Compared to determining whether the gas stove is in a dry-burning state solely based on temperature sensing data from the bottom of the pot, this application uses temperature sensing data from two different locations—the bottom of the pot and inside the gas stove itself—to determine whether the gas stove is in a dry-burning state. This avoids misjudgments caused by interference from temperature sensing data collected from the bottom of the pot, enhances anti-interference capabilities, improves the accuracy of judgment, and enhances the user experience.

[0089] Step S162: In response to the first temperature sensing information not meeting the first preset condition, or the second temperature sensing information not meeting the second preset condition, determine that the gas stove is in a non-dry-burning state.

[0090] When the first temperature sensing information does not meet the first preset condition, or when the second temperature sensing information does not meet the second preset condition, or when neither the first nor the second temperature sensing information meets their respective preset conditions, the gas stove is determined to be in a non-dry-burning state. In other words, as long as either the first or second temperature sensing information does not meet its corresponding preset condition, the gas stove is considered to be in a non-dry-burning state. This method reduces the probability of false judgments, thereby improving the user experience.

[0091] The non-dry-burning state can be either a wind-induced interference scenario or a normal cooking scenario. Since wind-induced interference is a scenario prone to misjudgment, this application avoids wind interference by placing the second temperature-sensing element within the main body, thereby improving the accuracy of the judgment.

[0092] Step S163: In response to the gas stove being in a non-dry-burning state, return to the execution of obtaining the gas stove's temperature sensing information and firepower adjustment information, and the subsequent steps.

[0093] When the gas stove is not in a dry-burning state, it can be understood that the gas stove is in a normal cooking state. The process returns to obtain the first and second temperature sensing information and the subsequent steps to continue monitoring whether the gas stove is in a dry-burning state.

[0094] This embodiment collects first temperature information from the bottom of the pot and second temperature information from the interior of the gas stove body using a first temperature sensor and a second temperature sensor. The gas stove is determined to be in a dry-burning state when both the first and second temperature information meet a first preset condition and a second preset condition. That is, the gas stove is only judged to be in a dry-burning state when both the first and second temperature information meet their corresponding preset conditions. Compared to determining whether the gas stove is in a dry-burning state solely based on temperature information from the bottom of the pot, this application uses temperature information from two different locations—the bottom of the pot and the interior of the gas stove body—to determine whether the gas stove is in a dry-burning state. This avoids misjudgments caused by interference from temperature information collected from the bottom of the pot. Furthermore, it further confirms whether the gas stove is in a flame adjustment state to further eliminate interference from flame adjustment in determining the dry-burning state, thereby enhancing anti-interference capabilities and improving the accuracy of the judgment, ultimately improving the user experience.

[0095] In one embodiment, the first preset condition includes a first rate threshold, the second preset condition includes a second rate threshold, the first temperature sensing information includes a first temperature rise rate, and the second temperature sensing information includes a second temperature rise rate. Step S161, in response to the first temperature sensing information meeting the first preset condition and the second temperature sensing information meeting the second preset condition, determines that the gas stove is in a dry-burning state, includes the following steps:

[0096] Step S1611: In response to the first temperature rise rate being greater than the first rate threshold and the second temperature rise rate being greater than the second rate threshold, it is determined that the gas stove is in a dry-burning state.

[0097] In this embodiment, the first temperature sensing information is the first temperature rise rate of the pot body, where the first rate threshold is the critical temperature rise rate of the pot body when it is in a dry-burning state; the second temperature sensing information is the second temperature rise rate of the gas stove body, where the second rate threshold is the critical temperature rise rate of the gas stove body when it is in a dry-burning state. The first temperature rise rate can be the same as the second temperature rise rate, or the second temperature rise rate can be less than the first temperature rise rate; this is not limited here. It is worth noting that the second temperature rise rate being less than the first temperature rise rate is within a reasonable range.

[0098] This embodiment determines whether the gas stove is in a dry-burning state by using a first temperature rise rate at the bottom of the pot and a second temperature rise rate at the main body of the gas stove. Both the first and second temperature rise rates are parameters continuously monitored during the operation of the gas stove. By verifying each other using two parameters, the accuracy of the judgment can be improved, thereby enhancing the safety performance of the gas stove and the user experience. In addition, the first and second temperature rise rates can quickly determine whether the gas stove is in a dry-burning state, allowing for early intervention and further improving the safety performance of the gas stove.

[0099] For example, the first temperature rise rate and the second temperature rise rate are X and Y, respectively, and the first rate threshold and the second rate threshold are B1 and B2, respectively. When the first temperature rise rate X is greater than the first rate threshold B1 and the second temperature rise rate Y is greater than the second rate threshold B2, it is determined that the gas stove is in a dry-burning state.

[0100] In one embodiment, to further improve the accuracy of the judgment, the third preset condition includes a third rate threshold. Step S1611, in response to the first temperature rise rate being greater than the first rate threshold and the second temperature rise rate being greater than the second rate threshold, determines that the gas stove is in a dry-burning state, and includes the following steps:

[0101] Step S1611a: In response to the first temperature rise rate being greater than the first rate threshold and the second temperature rise rate being greater than the second rate threshold, determine whether the second temperature rise rate and the first temperature rise rate are both greater than or equal to the third rate threshold.

[0102] The third rate threshold is the critical temperature change rate at which the pot body is in a dry-burning state when interference exists, such as wind interference. After determining that the first temperature rise rate is greater than the first rate threshold and the second temperature rise rate is greater than the second rate threshold, to improve the accuracy of the judgment, it is further determined whether both the second and first temperature rise rates are greater than or equal to the third rate threshold.

[0103] Step S1611b: In response to the fact that both the second temperature rise rate and the first temperature rise rate are greater than or equal to the third rate threshold, it is determined that the gas stove is in a dry-burning state.

[0104] When both the second and first temperature rise rates are greater than or equal to the third rate threshold, interference factors such as wind interference are eliminated, and it is determined that the gas stove is in a dry-burning state.

[0105] For example, the first temperature rise rate and the second temperature rise rate are X and Y, respectively; the first rate threshold and the second rate threshold are B1 and B2, respectively; and the third rate threshold B3 is the critical temperature change rate for determining wind interference. When the first temperature rise rate X is greater than the first rate threshold B1, the second temperature rise rate Y is greater than the second rate threshold B2, and X and Y are greater than or equal to B3, the gas stove is determined to be in a dry-burning state.

[0106] In one embodiment, the first preset condition includes a first rate threshold and a first temperature threshold, the second preset condition includes a second rate threshold and a second temperature threshold, the first temperature sensing information includes a first temperature and a first temperature rise rate, and the second temperature sensing information includes a second temperature and a second temperature rise rate. Referring to Figure 9, step S161, in response to the first temperature sensing information meeting the first preset condition and the second temperature sensing information meeting the second preset condition, determines that the gas stove is in a dry-burning state, includes the following steps:

[0107] Step S2611: In response to the first temperature being greater than the first temperature threshold, or in response to the first temperature rise rate being greater than the first rate threshold, it is determined that the first temperature sensing element is in a dry-burning state.

[0108] Wherein, the first rate threshold is the critical temperature rise rate of the pot body when the pot body is in a dry-burning state, the first temperature is the current temperature of the bottom of the pot body, and the first temperature threshold is the critical temperature when the pot body is in a dry-burning state.

[0109] When the first temperature exceeds a first temperature threshold, or when the first temperature rise rate exceeds a first rate threshold, or when both the first temperature and the first temperature rise rate exceed the first rate threshold, it is determined that the first temperature sensor is in a dry-burning state, or that the first temperature information collected by the first temperature sensor indicates that the pot body is in a dry-burning state. In other words, as long as either the first temperature or the first rate threshold meets its corresponding dry-burning state judgment condition, it can be determined that the first temperature information collected by the first temperature sensor indicates that the pot body is in a dry-burning state.

[0110] Step S2612: In response to the second temperature being greater than the second temperature threshold or the second temperature rise rate meeting the second preset condition, it is determined that the second temperature sensing element is in a dry-burning state.

[0111] The second rate threshold is the critical temperature rise rate of the body when the pot is in a dry-burning state, the second temperature is the current temperature of the body, and the second temperature threshold is the critical temperature of the body when the pot is in a dry-burning state.

[0112] When the second temperature exceeds the second temperature threshold, or when the second temperature rise rate exceeds the second rate threshold, or when both the second temperature and the second temperature rise rate exceed the second rate threshold, it is determined that the second temperature sensor is in a dry-burning state, or that the second temperature information collected by the second temperature sensor indicates that the pot body is in a dry-burning state. In other words, as long as either the second temperature or the second rate threshold meets its corresponding dry-burning state judgment condition, it can be determined that the second temperature information collected by the second temperature sensor indicates that the pot body is in a dry-burning state.

[0113] Step S2613: In response to the fact that both the first and second temperature sensing elements are in a dry-burning state, it is determined that the gas stove is in a dry-burning state.

[0114] When both the first and second temperature sensors are in a dry-burning state, that is, when both the first and second temperature sensors indicate that the pot is in a dry-burning state, the gas stove is considered to be in a dry-burning state.

[0115] In this embodiment, both the first and second temperature sensing information include the temperature rise rate and the current temperature. When either the temperature rise rate or the temperature meets the corresponding dry burning state judgment condition, the temperature sensing information collected by the temperature sensing element indicates that the pot body is in a dry burning state. That is, this embodiment improves the accuracy of judging whether the pot body is in a dry burning state by using multi-dimensional temperature data.

[0116] In one embodiment, to improve the accuracy of the judgment, the first preset condition includes: a first rate threshold, a first temperature threshold, and a first difference threshold. The second preset condition includes: a second rate threshold, a second temperature threshold, and a second difference threshold. The first temperature sensing information includes a first temperature, a first temperature rise rate, and a first difference; the second temperature sensing information includes a second temperature, a second temperature rise rate, and a second difference. Referring to Figure 10, step S161, in response to the first temperature sensing information meeting the first preset condition and the second temperature sensing information meeting the second preset condition, determines that the gas stove is in a dry-burning state, including the following steps:

[0117] Step S3611: In response to the first temperature being greater than the first temperature threshold, or the first temperature rise rate being greater than the first rate threshold, or the first difference being greater than the first difference threshold, it is determined that the first temperature sensing element is in a dry-burning state.

[0118] Wherein, the first rate threshold is the critical temperature rise rate when the pot is in a dry-burning state; the first temperature is the current temperature of the bottom of the pot; the first temperature threshold is the critical temperature when the pot is in a dry-burning state; the first difference is the difference between the first temperature and the steady-state temperature of the pot when it is in a steady state; the first difference threshold is the difference between the critical temperature and the steady-state temperature, or in other words, the difference between the first temperature threshold and the steady-state temperature of the pot. For example, when there is liquid in the pot, when the liquid in the pot is heated to a stable temperature of 100 degrees Celsius, the temperature of the bottom of the pot also remains at a stable temperature, and this stable temperature is the steady-state temperature of the pot.

[0119] When the first temperature exceeds a first temperature threshold, or when the first temperature rise rate exceeds a first rate threshold, or when the first difference exceeds a first difference threshold, it is determined that the first temperature sensor is in a dry-burning state, or that the first temperature information collected by the first temperature sensor indicates that the pot body is in a dry-burning state. In other words, as long as any one of the three parameters—first temperature, first rate threshold, and first difference—meets its corresponding dry-burning state judgment condition, it can be determined that the first temperature information collected by the first temperature sensor indicates that the pot body is in a dry-burning state.

[0120] Step S3612: In response to the second temperature being greater than the second temperature threshold, or the second temperature rise rate being greater than the second rate threshold, or the second difference being greater than the second difference threshold, it is determined that the second temperature sensing element is in a dry-burning state.

[0121] The second rate threshold is the critical temperature rise rate of the gas stove body when the pot is in a dry-burning state; the second temperature is the current temperature of the gas stove body; the second temperature threshold is the critical temperature of the gas stove body when the pot is in a dry-burning state; the second difference is the difference between the second temperature and the steady-state temperature of the gas stove body when the pot is in a steady state; the second difference threshold is the difference between the critical temperature and the steady-state temperature of the gas stove body, or the difference between the second temperature threshold and the steady-state temperature of the gas stove body. For example, when there is liquid in the pot, when the liquid in the pot is heated to a stable temperature of 100 degrees Celsius, the temperature of the gas stove body also remains at a stable temperature, and this stable temperature is the steady-state temperature of the gas stove body.

[0122] When the second temperature exceeds the second temperature threshold, or when the second temperature rise rate exceeds the second rate threshold, or when the second difference exceeds the second difference threshold, it is determined that the second temperature sensor is in a dry-burning state, or that the second temperature information collected by the second temperature sensor indicates that the pot body is in a dry-burning state. In other words, as long as any one of the three parameters—the second temperature, the second rate threshold, and the second difference—meets its corresponding dry-burning state judgment condition, it can be determined that the second temperature information collected by the second temperature sensor indicates that the pot body is in a dry-burning state.

[0123] Step S3613: In response to the fact that both the first and second temperature sensing elements are in a dry-burning state, it is determined that the gas stove is in a dry-burning state.

[0124] When both the first and second temperature sensors are in a dry-burning state, that is, when both the first and second temperature sensors indicate that the pot is in a dry-burning state, the gas stove is considered to be in a dry-burning state.

[0125] In this embodiment, both the first and second temperature sensing information include the temperature rise rate, temperature, and temperature difference. When any one of these three parameters meets the corresponding dry-burning state judgment condition, it can be determined that the temperature sensing information collected by the temperature sensing element indicates that the pot is in a dry-burning state. This embodiment improves the accuracy of dry-burning state judgment by using multi-dimensional temperature data to determine whether the pot is in a dry-burning state.

[0126] In one embodiment, to improve the user experience, the anti-dry-burning system further includes a prompting component configured to output prompt information. The control method for the anti-dry-burning system further includes:

[0127] Step S170: In response to the gas stove being in a dry-burning state and not in a flame adjustment state, the control prompt component outputs a prompt message.

[0128] When the gas stove or pot is determined to be in a dry-burning state and the gas stove is not in the flame adjustment state, the system also controls the prompting component to output a prompt message to remind the user. This prompt message can be of various types, including sound, light, text, graphics, and vibration; there is no limitation on the type of prompt message used.

[0129] This implementation controls the prompting component to output a prompt message when the gas stove is in a dry-burning state and the gas stove is not in the flame adjustment state. This allows the user to discover that the pot is in a dry-burning state as early as possible based on the prompt message. In this way, the user can discover the cooking problem in time and intervene in the cooking in time, thereby improving the user experience.

[0130] In one embodiment, to improve the user experience and meet the user's needs for cooking methods such as dry pot cooking, the gas stove further includes a first switch assembly. The first switch assembly is configured to turn off or on the gas stove's anti-dry-burning function. Referring to Figure 11, the control method further includes:

[0131] Step S181: Detect the switching state of the first switching component.

[0132] Before monitoring whether the pot is in a dry-burning state, or throughout the cooking process, the on / off status of the first switch component is detected to determine whether the user needs the anti-dry-burning monitoring function.

[0133] Step S182: In response to the first switch component being in the open state, execute the steps of acquiring the temperature sensing information and firepower adjustment information of the gas stove and the subsequent steps.

[0134] When the first switch component is detected to be in the on state, it means that the user needs the anti-dry burning monitoring function to start the process of obtaining the gas stove's temperature sensing information and gas stove's firepower adjustment information, as well as subsequent steps.

[0135] Step S183: In response to the first switch component being in the closed state, return to the step of detecting the switching state of the first switch component.

[0136] When the first switch component is detected to be in a closed state, it means that the user does not want to enable the anti-dry burning monitoring function, and the process returns to the step of detecting the switch status of the first switch component.

[0137] In one embodiment, to improve the user experience and meet the user's demand for cooking methods such as dry pot cooking, the gas stove further includes a second switch assembly. The second switch assembly is configured to delay the gas stove from operating. Referring to Figure 12, step S130, in response to the gas stove not being in the flame adjustment state, involves controlling the gas stove to stop operating, which includes:

[0138] Step S131: In response to the gas stove not being in the flame adjustment state, obtain the on / off state of the second switch component.

[0139] When the pot is detected to be in a dry-burning state and the gas stove is not in the flame adjustment state, the switch status of the second switch component is further obtained to determine whether the user needs to delay the shutdown.

[0140] Step S132: In response to the second switch assembly being in the closed state, control the gas stove to stop working.

[0141] When the gas stove is detected to be in a dry-burning state and not in the flame adjustment state, and when the user has not turned on the second switch component, the gas stove will be immediately controlled to stop working.

[0142] Step S133: In response to the second switch component being in the on state, control the gas stove to stop working after a preset time.

[0143] When the gas stove is detected to be in a dry-burning state and not in a flame adjustment state, and when the user turns on the second switch component, the gas stove is controlled to stop working after a preset time.
