[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0027] This application provides a stove and a method for controlling its firepower, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of a stove provided in this application. Specifically, the stove 10 includes a burner 11, a camera assembly 12, a first sensor 13, and a second sensor 14.
[0028] The burner head 11 is located on the stove 30 and is used to heat the pot 20 on it. The burner head 11 has multiple heat levels, each with a different intensity. The structure of the burner head 11 is within the scope of what those skilled in the art can understand and will not be described in detail here.
[0029] A camera assembly 12 is positioned above the burner head 11. The camera assembly 12 monitors the state of the cookware 20 on the burner head 11. The camera assembly 12 can capture images of the cookware 20, and by analyzing the captured images, obtain the state of the cookware 20 and its cooking information. The state of the cookware 20 refers to its movement information, such as whether the cookware 20 is being tossed around. The camera assembly 12 can monitor whether the cookware 20 is positioned on the burner head 11. The cooking information of the cookware 20 includes whether there is food inside the cookware 20, i.e., whether the cookware 20 is in a dry-heat state.
[0030] Furthermore, in Figure 1 In the illustrated embodiment, the camera assembly 12 is mounted on the range hood above the burner 11. In other embodiments, the camera assembly 12 may also be mounted on a cabinet above the burner 11 or on the wall behind the burner 11.
[0031] The first sensor 13 is mounted on the burner head 11 and is used to sense the pot 20 on the burner head 11. The first sensor 13 can be a distance sensor, used to sense the distance between the pot 20 and the burner head 11. When the distance between the pot 20 and the burner head 11 is greater than 0, it can be confirmed that the pot 20 has left the burner head 11; when the distance between the pot 20 and the burner head 11 is equal to 0, it can be confirmed that the pot 20 is on the burner head 11. That is, the first sensor 13 can determine whether there is a pot 20 on the burner head 11.
[0032] The second sensor 14 is located on the burner head 11 and is used to measure the temperature of the cookware 20 on the burner head 11. The second sensor 14 can be a temperature sensor, through which the temperature of the cookware 20 on the burner head 11 can be obtained.
[0033] Please see Figure 2 As shown, Figure 2 This is a flowchart illustrating an embodiment of a fire control method for a stove provided in this application. Specifically, the fire control method includes:
[0034] S11: In response to the cookware leaving the burner, detect the status of the cookware.
[0035] When the cookware is confirmed to have left the burner, its status after leaving the burner is detected. The status of the cookware can include being in a tossing position, not being tossing, or other states.
[0036] Optionally, a first sensor can be used to detect whether the cookware has left the burner. For example, if the first sensor is a distance sensor, the distance between the cookware and the burner can be detected to confirm whether the cookware has left the burner. Alternatively, a camera assembly can be used to confirm whether the cookware has left the burner. Preferably, the first sensor combined with a camera assembly can be used to confirm whether the cookware has left the burner, thus improving the accuracy of the judgment and reducing false alarms.
[0037] Optionally, the status of the cookware can also be detected by the first sensor after it leaves the burner. For example, after the cookware leaves the burner, a distance sensor detects the distance between the cookware and the burner, and by analyzing changes in this distance, it can be determined whether the cookware is in a tossing motion. Specifically, if the distance between the cookware and the burner changes within a preset range, it can be confirmed that the cookware is in a tossing motion. After the cookware has been tossed, it will return to the burner. If the distance between the cookware and the burner exceeds the preset range, it can be confirmed that the user is moving the cookware, the cookware is not in a tossing motion, and the cookware may not return to the burner.
[0038] In other embodiments, the state of the cookware can also be detected using a camera component. Specifically, such as... Figure 3 As shown, the step of detecting the status of the cookware in response to the cookware being removed from the burner may include:
[0039] S111: Obtain the feature information of the cookware through the camera component.
[0040] Once the cookware is confirmed to have left the burner, an image of the cookware is captured by a camera component. The characteristic information of the cookware is then obtained based on this image. This characteristic information may include the range of motion of the cookware and the type of food being cooked inside.
[0041] The aforementioned feature information is used to determine the state of the cookware. For example, if the cookware's feature information indicates that it is moving back and forth within a predetermined range, it can be determined that the cookware is in a tossing state. If the cookware's position exceeds the preset range, it can be confirmed that the cookware is not in a tossing state. If the cookware is moving further and further away from the stove, it can be confirmed that the cookware is in a moving state. For instance, if a user has a habit of tossing a certain ingredient while cooking, if it is confirmed that the food in the cookware is an ingredient that is frequently tossed, it can be confirmed that the cookware is in a tossing state. If it is confirmed that the food in the cookware is not that ingredient, it can be confirmed that the cookware is not in a tossing state.
[0042] S112: Match the feature information with historical cooking data to confirm whether the pot is in the tossing state, so as to obtain the state of the pot, wherein the preset state is the non-tossing state.
[0043] The acquired cookware feature information is matched with historical cooking data, which includes the cookware's state data during previous cooking sessions. This state data includes data on the cookware when it was in the "tossing" position and data on the cookware when it was not in the "tossing" position.
[0044] The real-time feature information of the cookware is matched with the above data. If the feature information of the cookware matches the state data when the cookware is in the tossing state, it can be confirmed that the cookware is in the tossing state. If the feature information of the cookware matches the state data when the cookware is not in the tossing state, it can be confirmed that the cookware is not in the tossing state.
[0045] When the cookware is in the tossing motion, it will return to the burner after the tossing is complete. When the cookware is not in the tossing motion, it will move away from the burner and may not return to the burner.
[0046] In the above embodiments, the characteristic information of the pot is obtained by the camera component, and the pot is confirmed to be in the state of tossing the pot based on the characteristic information. This method is simple to operate and has high accuracy.
[0047] S12: In response to the cookware being in a preset state, obtain the duration of the cookware being away from the stove.
[0048] When the cookware is confirmed to be in the preset state, it can be assumed that the cookware may not return to the burner. Therefore, the heat of the burner can be adjusted. The preset state can be the non-tossing state, that is, when the cookware leaves the burner and is not in the tossing state, it can be assumed that the cookware may not return to the burner. At this time, the duration of the cookware leaving the burner is obtained.
[0049] In other embodiments, the preset state may also be that the distance between the cookware and the burner exceeds a threshold. That is, when it is confirmed that the distance between the cookware and the burner is too far, it can be assumed that the cookware may not return to the burner.
[0050] S13: Adjust the burner's heat based on the duration.
[0051] After obtaining the duration of the cookware being removed from the burner, the burner's heat is adjusted based on this duration. Adjustments to the burner's heat include reducing the flame or turning off the burner altogether, to save energy without affecting normal user operation.
[0052] In some specific embodiments, such as Figure 4 As shown, Figure 4 yes Figure 2 A flowchart illustrating an embodiment of step S13 shows that, specifically, the step of adjusting the burner's heat based on the duration may include:
[0053] S131: When the duration exceeds a first preset time, reduce the heat of the burner.
[0054] If the cookware remains off the burner for longer than a preset time, the burner's heat will be reduced to save energy. The preset time can be a user-defined duration, ranging from 20 to 40 seconds. For example, a preset time of 30 seconds would reduce the burner's heat if the cookware remains off the burner for more than 30 seconds.
[0055] The first preset time can be relatively short, so that the heat of the stove can be reduced in a short time to save energy. The heat of the stove is not turned off. When the pot is returned to the stove, the heat of the stove can be automatically adjusted back to the original level so as not to affect the user's normal use.
[0056] S132: In response to a duration greater than a second preset time, control the burner head to turn off, wherein the second preset time is greater than the first preset time.
[0057] After the burner's heat is reduced, if the duration for which the cookware remains off the burner is greater than a second preset time, the burner will shut off. The second preset time is greater than the first preset time. In other words, the burner's heat is reduced first, and if the duration for which the cookware remains off the burner is greater than the second preset time, the burner will shut off.
[0058] The second preset time can be set by the user according to their cooking habits. The range of the second preset time can be 50-70 seconds. For example, the second preset time could be 60 seconds. If the pot remains off the burner for more than 60 seconds, the burner will be turned off. In other embodiments, the second preset time can be automatically set based on the user's historical cooking data. For example, if historical cooking data shows that the pot rarely returns to the burner after 2 minutes, it can be assumed that the pot has been moved elsewhere and the user will not use the burner again for this cooking session. In this case, the second preset time can be set to 2 minutes, and the burner will be turned off if the pot remains off the burner for more than 2 minutes.
[0059] In the above embodiments, after the cookware leaves the burner, the status of the cookware is monitored. If the status of the cookware is in the preset state, it can be assumed that the cookware will not return to the burner in a short period of time. Therefore, the firepower of the burner can be adjusted to make the firepower control of the burner more intelligent. While meeting the user's needs, it saves energy and has a high degree of intelligence.
[0060] like Figure 5 As shown, Figure 5 This is a flowchart illustrating another embodiment of a fire control method for a stove provided in this application. Specifically, in this embodiment, the fire control method may include:
[0061] S21: The temperature of the cookware is obtained through the second sensor, and the cooking information of the cookware is obtained through the camera component, wherein the cooking information of the cookware includes whether the cookware is in a dry-heat state.
[0062] A second sensor, which can be a temperature sensor, is installed on the burner. This second sensor can obtain the temperature of the pot on the burner. When cooking, the temperature of the pot should be below a certain threshold. If the temperature of the pot exceeds the threshold, the pot may be in a state of dry burning.
[0063] The camera component acquires cooking information about the cookware, including whether the cookware is in a dry-heat state or not. The camera component can then determine whether the cookware is in a dry-heat state.
[0064] For example, the second sensor obtains the temperature of the cookware as 300 degrees Celsius, and the camera component obtains the cooking information of the cookware as being in a dry-heating state.
[0065] S22: Adjust the burner's heat based on the cookware's temperature and cooking information.
[0066] After obtaining the temperature and cooking information of the cookware, the burner's heat is adjusted based on this information. This reduces misjudgments and improves the accuracy of burner heat control.
[0067] Specifically, the burner can control the heat output by determining whether the temperature of the cookware exceeds a temperature threshold and whether the cookware is in a dry-burning state.
[0068] For example, in some specific embodiments, when it is confirmed that the temperature of the pot is greater than a temperature threshold, and the camera component determines that the pot is in a dry-burning state, the burner is controlled to turn off. In this method, both the camera component and the temperature of the pot confirm that the pot is in a dry-burning state, so controlling the burner to turn off at this time is highly accurate and improves the safety of stove use.
[0069] In other embodiments, the burner's heat is not adjusted when it is confirmed that the temperature of the cookware is below a temperature threshold and the cookware is not in a dry-burning state.
[0070] In other embodiments, when it is confirmed that the temperature of the cookware is below a temperature threshold and the cookware is in a dry-burning state, the burner is turned off to prevent the cookware from continuing to dry-burn and causing danger.
[0071] In other embodiments, when it is confirmed that the temperature of the cookware is greater than the temperature threshold and the cookware is not in a dry-burning state, the heat can be reduced or turned off.
[0072] In other embodiments, when it is confirmed that the temperature of the cookware is greater than a temperature threshold and the cookware is in a dry-burning state, the burner is controlled to turn off.
[0073] In the above embodiments, the stove fire is controlled by the temperature of the cookware and the cooking information captured by the camera component, providing dual protection against fire failure and avoiding misjudgment caused by high temperatures due to traditional anti-dry burning, thus improving the safety of stove use.
[0074] S23: Determine whether the cookware has left the burner using the first sensor and / or camera assembly.
[0075] A first sensor, which can be a distance sensor, is installed on the burner head. This first sensor can detect whether the cookware is on the burner head. The presence of the cookware on the burner head can be determined by this first sensor and / or a camera assembly.
[0076] For example, the position of the cookware can be sensed by a first sensor, and the position information can be verified by a camera component. Only when both methods confirm that the cookware has left the burner can it be confirmed that the cookware has left the burner. In this way, detecting the status of the cookware through two methods can improve the accuracy of the detection.
[0077] S24: In response to the cookware leaving the burner, detect the status of the cookware.
[0078] Step S24 is the same as step S11, and will not be repeated here.
[0079] S25: In response to the cookware being in a preset state, obtain the duration of the cookware being away from the stove.
[0080] Step S25 is the same as step S12, and will not be described again here.
[0081] S26: Adjust the firepower of the burner head based on the duration.
[0082] Step S26 is the same as step S13, and will not be repeated here.
[0083] In the above embodiments, during stewing or other cooking processes, the second sensor on the burner provides dual protection against flameout based on the range hood's vision and the burner itself, avoiding misjudgments caused by traditional high-temperature anti-dry-burning methods. Furthermore, the accuracy of detection is improved by combining the first sensor and camera components to confirm whether the pot has left the burner. Once the pot is off the burner, its status is monitored. If the pot is in a preset state, it is assumed that it will not return to the burner in a short time. Therefore, the burner's heat can be adjusted, making heat control more intelligent. This achieves energy savings while meeting user needs, demonstrating a high level of intelligence.
