[0001] This application claims priority to Chinese patent application CN202510330554.6, filed on March 19, 2025, entitled “Stove”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of kitchen appliance technology, specifically to a control method for a stove, a computer-readable storage medium, and a computer device. Background Technology

[0003] A cooktop, as a type of kitchen appliance, primarily cooks food by supplying heat to pots and pans placed on the burner. If the cooktop includes a proportional valve, adjusting its on / off state and opening degree allows for different heat levels, thus enabling more efficient cooking.

[0004] If the pot is about to overflow, the heat should be reduced. Because even at a low heat setting, the combustion power is still relatively high, if overflow has already occurred or is about to happen and is difficult to prevent, even adjusting to a low heat setting will not suppress or eliminate the overflow. In such cases, the stovetop usually needs to be turned off to prevent or eliminate the overflow. This interrupts the cooking process. Interruptions to the cooking process will affect the quality of the food and, to some extent, the cooking experience. Furthermore, for stovetops with automatic heat adjustment, turning off the stovetop will interrupt the adjustment logic, which will significantly affect the level of automation in the cooking process. Summary of the Invention

[0005] This application aims to solve at least part of the above-mentioned technical problems and / or at least part of the above-mentioned technical problems, specifically, how to ensure the sustainability of cooking without interrupting the current cooking process.

[0006] In a first aspect, this application provides a method for controlling a stove, the stove including a gas circuit assembly, the gas circuit assembly including a proportional valve assembly, the proportional valve assembly including: a valve body; an inlet valve disposed at an inlet port of the valve body; and at least one outlet valve disposed at at least one outlet port of the valve body; wherein the valve body is provided with a communication structure in a passage corresponding to the inlet port and at least one outlet port; the control method includes: opening the inlet valve and closing the outlet valve according to the overflow state of the pot (a pot placed above the burner, such as a pot that can cook food by steaming, boiling, stewing, frying, etc.), so that: gas reaches the burner of the stove through the communication structure.

[0007] This configuration effectively prevents cooking interruptions caused by turning off the stove, by using the lowest possible heat setting. Even with the gas valve closed, the lowest heat setting still provides heat, preventing the burner from extinguishing. Thus, on one hand, the lowest heat setting effectively suppresses / eliminates overflow, ensuring the continuity of the cooking process. On the other hand, by preventing cooking interruptions due to turning off the stove, the continuity of the entire cooking process is guaranteed.

[0008] It is understandable that those skilled in the art can determine the form of the cooking state, the specific detection method, and its correspondence with the lowest heat setting based on actual needs. For example, the overflow state can be determined by the parameters of the stove itself, the detection components configured on the stove, and the detection components configured on other equipment related to the stove. For instance, the overflow state of the pot can be determined by whether the heat is extinguished or by image data.

[0009] Furthermore, it is understood that those skilled in the art can determine the specific methods for judging the overflow state and the types it includes based on actual needs. For example, the overflow state can include two states: impending overflow and already overflowed. Both the impending overflow and already overflowed states can further include multiple settings. Taking the already overflowed state as an example, it can include, but is not limited to, several states such as slightly stable, slightly rising, rapid overflow, and severe overflow.

[0010] In one possible implementation of the control method for the above-mentioned stove, the "determining the overflow state of the pot" includes: determining the overflow state of the pot based on the collected image data of the pot.

[0011] This configuration allows for the intuitive acquisition of the current overflow status through image data.

[0012] Image data can be acquired using image detection components such as cameras and image sensors. These components can be installed in the space where the cooktop is located (e.g., above the cooktop in the kitchen) or on other related devices (e.g., a range hood). To ensure the reliability of the control logic, the current overflow status of the pot can be determined using one or more image data points, such as through multiple-choice analysis, comprehensive analysis of multiple results, or analysis of intermediate image data after stitching together multiple images.

[0013] In one possible implementation of the control method for the aforementioned stove, the step of "opening the air inlet valve and closing the air outlet valve according to the overflow state of the pot, so that the gas reaches the burner of the stove through the connecting structure" includes: obtaining the current firepower of the stove; determining whether the current firepower is less than or equal to a preset firepower; if so, opening the air inlet valve and closing the air outlet valve according to the overflow state, so that the gas reaches the burner of the stove through the connecting structure.

[0014] This configuration allows for the sustainability of cooking even when it's impossible to suppress overflow by reducing the heat, by operating at the lowest possible heat setting.

[0015] It is understandable that those skilled in the art can determine the preset firepower level based on actual needs. This could be the lowest firepower setting, or a lower firepower setting close to the lowest setting.

[0016] In one possible implementation of the control method for the above-mentioned stove, the step of "determining whether the current firepower is less than or equal to the preset firepower" includes: if not, adjusting the current firepower; and during the adjustment of the current firepower, continuously determining the overflow state of the pot; and based on the continuously determined overflow state, determining whether to open the air inlet valve and close the air outlet valve so that the gas reaches the burner of the stove through the connecting structure.

[0017] With this configuration, it is possible to reliably suppress / eliminate the overflow of the pot based on the current heat output.

[0018] The phrase "adjusting the current heat" should begin with lowering the current heat. If a consistently observed overflow indicates that the reduction in heat has completely suppressed the overflow, then there is no need to run the stove at its lowest heat setting. If the consistently observed overflow indicates that the reduction in heat is slow to suppress the overflow or cannot completely suppress it (assuming it has already been lowered to the preset heat), then the stove can be run at its lowest heat setting. If the consistently observed overflow indicates that the reduction in heat is fast to suppress the overflow, then the stove's heat can be appropriately increased to improve cooking efficiency.

[0019] In one possible implementation of the above-mentioned stove, the connecting structure includes one or more; and / or the connecting structure is provided in the passage in a switchable or normally open manner; and / or the same connecting structure can be connected to the passage of the air inlet valve port and one or more of the air outlet valve ports.

[0020] This configuration provides a possible form for a proportional valve assembly with a connected structure.

[0021] In one possible implementation of the control method for the above-mentioned stove, the at least one gas outlet valve includes: a first gas outlet valve; and a second gas outlet valve disposed between the gas inlet valve and the first gas outlet valve; wherein the connecting structure is disposed in the passage between the gas inlet valve and the second gas outlet valve.

[0022] This configuration indicates the location of the connecting structure on the proportional valve assembly.

[0023] In one possible implementation of the control method for the above-mentioned stove, the valve body includes: a first passage section arranged along the axial direction of the air inlet valve; and a second passage section having an angle with the first passage section; wherein the air inlet valve port can be connected to the air outlet valve port sequentially through the first passage section and the second passage section; wherein the connecting structure is arranged in the second passage section.

[0024] With this configuration, it is possible to achieve a gas supply quality corresponding to the interconnected structure that is close to that of the second outlet valve.

[0025] In one possible implementation, the first passage segment is substantially perpendicular to the second passage segment; and / or the axis of the connecting structure is substantially parallel to the axis of the exhaust valve.

[0026] This configuration provides a specific way to set up the connectivity structure on the second path.

[0027] In one possible implementation, viewed along the direction of air supply to the gas path assembly, the connecting structure is located on the valve body near the outlet valve port.

[0028] This configuration allows for a further guarantee that the gas supply quality corresponding to the connecting structure is close to that of the second outlet valve.

[0029] In one possible implementation, the communication structure is located at a non-central section of the valve body.

[0030] This configuration allows for better assurance of gas supply quality based on the interconnected structure.

[0031] In one possible implementation, the cross-sectional dimension of the connecting structure is smaller than the cross-sectional dimension of the outlet valve; and / or, when viewed along the direction of air supply to the air passage assembly, the cross-sectional dimension of the downstream side of the connecting structure is greater than or equal to the cross-sectional dimension of the upstream side.

[0032] In a possible embodiment, the communication structure includes a first communication section and a second communication section, wherein the first communication section is located upstream of the second communication section along the gas supply direction of the gas path assembly, and the cross-sectional dimension of the second communication section is larger than that of the first communication section.

[0033] For the above control method of a cooking stove, in a possible embodiment, in the scenario where "the intake valve is opened and the outlet valve is closed, so that fuel gas reaches the burner of the cooking stove through the communication structure", the pot overflow state is continuously determined; and the firepower of the cooking stove is adjusted according to the continuously determined overflow state.

[0034] If the continuously determined overflow state indicates that the reduction of firepower has completely suppressed the overflow phenomenon, the minimum fire gear can be continuously operated or the firepower can be appropriately increased. If the overflow phenomenon is suppressed slowly, or the gradually rising overflow phenomenon is exactly suppressed, the minimum fire gear can be continuously operated. Alternatively, if even a minimum increase in firepower would cause the overflow phenomenon to reoccur, the minimum fire gear is continuously operated. If not, the firepower can be appropriately increased to improve cooking efficiency. For example, it can be fixed at a certain gear or adjusted among several gears. If the continuously determined overflow state indicates that the current overflow phenomenon still cannot be suppressed / eliminated when operating at the minimum fire gear, the cooking stove can be turned off (adjusting the firepower to 0) to ensure cooking safety.

[0035] For the above control method of a cooking stove, in a possible embodiment, the control method further comprises: determining the operating parameters of a range hood configured on the cooking stove according to the pot overflow state.

[0036] Through this configuration, the linkage between the range hood and the cooking stove can be achieved to ensure the environmental quality of the kitchen space where the cooking stove is located. For example, the range hood can be operated according to the overflow state. Alternatively, the operating parameters of the range hood can be adjusted according to the overflow state (e.g., when the range hood has already been in operation before this).

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0073] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can still be implemented without certain specific details. In some examples, the detailed structure and principles of stoves well-known to those skilled in the art are not described in detail, in order to highlight the main points of this application.

[0074] Main reference Figure 1 and Figure 2 In one possible implementation, the stove 100 mainly includes a main on / off valve 1, a proportional valve assembly 2, a gas circuit assembly, and at least one burner. The gas circuit assembly supplies gas to the burner. The main on / off valve 1 is typically located on the main gas circuit 31 of the gas circuit assembly and is primarily used to control the overall gas flow in the gas circuit assembly. The proportional valve assembly 2 is located downstream of the main on / off valve 1 along the gas supply direction and is primarily used to adjust the burner's flame intensity.

[0075] In this example, the burner includes three components, as shown below. Figure 1In the orientation as shown, counting from left to right, they are respectively recorded as left burner 41, middle burner 42 and right burner 43, wherein both the left burner 41 and the right burner 43 adopt a structural form of gas supply through two gas paths. For example, both the left burner 41 and the right burner 43 comprise an outer ring and an inner ring, and the gas path assembly comprises a first gas path (which may be called an outer ring gas path) and a second gas path (which may be called an inner ring gas path) corresponding to the outer ring and the inner ring of the left / right burners. In this way, fuel gas can supply gas to the outer ring and the inner ring of the burners through the outer ring gas path and the second gas path respectively. The middle burner 42 adopts a structural form of gas supply through one gas path. For example, the middle burner 42 comprises an inner ring, and the gas path assembly supplies gas to the inner ring of the middle burner 42 through an inner ring gas path corresponding to the middle burner 42. Wherein, three proportional valve assemblies 2 are respectively configured for the three burners, and through the cooperation of the on-off main valve 1 and the proportional valve assemblies 2, the fire power of the three burners can be adjusted. Obviously, the number of burners and their gas supply modes can be flexibly selected according to actual needs. For example, the middle burner 42 can also adopt a structural form of gas supply through two gas paths, and the left / right burners can adopt a structural form of gas supply through one gas path or more than two gas paths, etc.

[0076] For example, in this example, the structures of the proportional valve assemblies 2 corresponding to the three burners are substantially the same. Obviously, different proportional valve assemblies can also be configured for different burners according to actual needs. For example, the proportional valve assemblies corresponding to the left / right burners and the proportional valve assembly corresponding to the middle burner 42 can be different.

[0077] In this example, the cooking appliance 100 further comprises a main control board 5, a display board 6 and a wireless communication module 7. Wherein, the main control board 5 is mainly used for issuing opening / closing parameters for controlling the main valve and the proportional valve assemblies 2 so as to adjust the fire power of the burners; the display board 6 is mainly used for displaying operating parameters such as fire power corresponding to the burner heads of the three burners. The wireless communication module 7 (such as a Wi-Fi module, a Bluetooth module, etc.) is mainly used for realizing signal connection between the main control board 5 and other data. On this basis, it is expected to realize the linkage between the cooking appliance 100 and other devices. For example, whether pot overflow occurs can be determined based on image data above the cooking appliance 100 collected by an image detection component such as a camera component installed on a range hood, and the reliability of cooking can be ensured by controlling the operating parameters of the cooking appliance 100. For example, the image data can be directly transmitted to the main control board 5 through the wireless communication module 7, and analyzed by the main control board 5 of the cooking appliance 100; the analysis result based on the image data can also be transmitted to the main control board 5 of the cooking appliance 100, and the main control board 5 can directly output a corresponding adjustment signal according to the pre-established mapping relationship between the image data and the on-off assembly / proportional valve assembly.

[0078] Mainly refer to Figure 3 and Figure 4In one possible implementation, the proportional valve assembly 2 mainly includes a valve body 21, which has a gas passage that allows gas flow. The valve body 21 has an inlet valve 211 and at least one outlet valve. The inlet valve 211 is equipped with an inlet valve 211, which mainly works in conjunction with the aforementioned on / off main valve 1 to ensure gas intake for the proportional valve assembly 2. The outlet valve is equipped with an outlet valve, and the outlet port can connect to the aforementioned outer or inner ring gas path. The outlet valve mainly adjusts the amount of gas supplied to the burner by regulating the opening degree of the outlet valve, thereby adjusting the burner's flame intensity. In this example, there are two outlet valve ports, which are referred to as the first outlet valve port and the second outlet valve port, respectively. Correspondingly, the outlet valves configured at the first outlet valve port and the second outlet valve port are referred to as the first outlet valve 221 and the second outlet valve 222, respectively. The first outlet port 251 (outer ring outlet port) corresponding to the first outlet valve port can be connected to the outer ring air path. The second outlet valve port is located between the inlet valve 211 and the first outlet valve port. The second outlet port 252 corresponding to the second outlet valve port can be connected to the inner ring air path.

[0079] The valve body 21 has internal passages, including a first passage 231 located between the first and second outlet valve ports and a second passage 232 located between the second outlet valve port and the inlet valve 211 port. In this way, the regulation of the gas in the outer ring gas path corresponding to the first outlet valve port is achieved by the joint regulation of the first outlet valve 221 and the second outlet valve 222, and the regulation of the gas in the inner ring gas path corresponding to the second outlet valve port is achieved by the regulation of the second outlet valve 222.

[0080] Obviously, the description of the pathways, including the first pathway 231 and the second pathway 232 connected in series, is merely an exemplary description; it can also be implemented in other ways, such as through parallel connection. Exemplarily, two first pathways 231 are provided between the intake valve 211 and the first outlet valve. One of these first pathways 231 is connected in parallel with the second pathway 232 and can therefore independently supply gas to the first outlet valve. The other first pathway 231 is similar in structure to the aforementioned one, forming a gas supply path corresponding to the first outlet valve by connecting it in series with the second pathway 232. In this way, the gas can reach the first outlet valve through two paths. Based on this, the gas in the outer ring gas path corresponding to the first outlet valve can be regulated by a combination of independent and coordinated regulation.

[0081] In one possible implementation, a connecting structure 24 is provided on the first passage 231 and / or the second passage 232. The connecting structure 24 can be a connecting hole opened on the valve body 21, a separately added pipe, etc. In this way, even when the main valve 1 and the inlet valve 211 are open, gas can still enter the corresponding gas passage even when the first / second outlet valves are closed, thus ensuring that the burner of the stove still has a certain firepower. For the same passage, the connecting structure 24 can include one or more, for example, using a multi-point arrangement to ensure the gas intake volume or uniformity. The connecting structure 24 can be a normally open structure or a structure with switchable connection states. For example, it can be automatically adjusted in a manner similar to the inlet / outlet valves, or it can be blocked by manual operation / adjustment. For example, it can be manually adjusted once at the factory stage, thus saving mold opening costs. Alternatively, during the usage phase, the connection state of the connecting structure 24 can be switched manually. For example, while ensuring connection, the specific opening degree can be adjusted (e.g., from 100% to 70%) to adjust the firepower of the burner under the corresponding operating conditions.

[0082] The upstream and / or downstream sides of the connecting structure 24 may have one or more connecting ports. If there is one connecting port on both the upstream and downstream sides, the connecting structure 24 can be used to connect to a gas path corresponding to a single outlet valve. If multiple connecting ports are included, it is possible to connect to multiple gas paths through a single connecting structure 24. For example, the downstream side of the connecting structure 24 includes two branches: one branch connects to the outer ring gas path, and the other branch connects to the inner ring gas path.

[0083] In one possible implementation, the connecting structure 24 is disposed on the second passage 232 between the intake valve 211 and the second outlet valve 222, such as a connecting hole section opened on the valve body 21. In this way, when the main valve 1 / intake valve 211 is open and the first / second outlet valve is closed, the gas can reach the inner ring gas path via the second passage 232 and the connecting structure 24 disposed thereon, thus enabling the burner to provide a certain amount of heat. In this example, the connecting structure 24 is disposed in a non-central position of the valve body. Figure 4 It can be seen that the connected structure 24 is located on one side of the midsection position.

[0084] In one possible implementation, the second passage 232 includes a first passage segment 2321 arranged approximately along the axial direction of the intake valve 211, and a second passage segment 2322 forming an angle with the first passage segment 2321. The intake valve 211 port corresponding to the intake valve 211 can sequentially communicate with the second outlet valve port via the first passage segment 2321 and the second passage segment 2322. A connecting structure 24 is disposed in the second passage segment 2322. By placing the connecting structure 24 near the downstream side of the second passage segment 2322, the position communicating with the inner ring gas path is close to the second outlet valve port. This makes the gas flow properties more similar to those when the second outlet valve 222 is open, thereby ensuring the gas supply quality. For example, the connecting structure 24 can be further positioned in the second passage segment 2322 near the second outlet valve port to further ensure the gas supply quality. Furthermore, the combination of the two connecting segments ensures the compact structure within the valve body 21, which has multiple outlet valves. The structural form of the second passage segment 2322 can be reasonably selected based on the structure of the valve body 21, the number of outlet valves, and their relative positions. For example, the second passage segment 2322 can be a straight line and / or a curve. For instance, the second passage segment 2322 can be a broken line composed of straight lines, a combination of multiple curves, or a combination of straight lines and curves. If the connection point with the first passage segment 2321 is a curve, the angle between the first passage segment 2321 and the second passage segment 2322 can be described using the tangent at the connection point.

[0085] In one possible implementation, the first passage segment 2321 and the second passage segment 2322 are substantially perpendicular. As per... Figure 4 The first passage segment 2321 is a vertical passage segment parallel to the axis of the intake valve 211, and the second passage segment 2322 is approximately a horizontal passage segment. The connecting structure 24 is opened approximately along the wall thickness of the first passage segment 2321; therefore, the axis of the connecting structure 24 is approximately parallel to the axis of the second exhaust valve 222. Alternatively, the axis of the connecting structure 24 can be adjusted to a curve or a straight line with a certain angle to the axis of the second exhaust valve 222, depending on actual needs.

[0086] Main reference Figure 4 and Figure 5In one possible implementation, the cross-sectional (radial) dimension of the connecting structure 24 is smaller than the cross-sectional dimension of the gas outlet valve, such as not exceeding 1 / 25 to 1 / 10 of the cross-sectional dimension of the gas outlet valve, for example, not exceeding 1 / 30 of the cross-sectional dimension of the gas outlet valve. In this way, compared to the case where the first / second gas outlet valve is open, the gas flow rate in the gas passage constructed based on the connecting structure 24 is significantly reduced. Therefore, a very low flame setting of the burner can be constructed based on this gas passage, which can serve to prevent flameout during cooking, or ensure cooking reliability while preventing flameout in situations where the gas supply needs to be shut off.

[0087] In one possible implementation, the cross-sectional dimension of the downstream side of the connecting structure 24 is greater than or equal to the cross-sectional dimension of the upstream side. As in this example, the connecting structure 24 includes a first connecting segment 241 on the upstream side and a second connecting segment 242 on the downstream side. The cross-sectional dimensions of the first connecting segment 241 are approximately the same, and the dimension of the downstream side of the second connecting segment 242 is greater than the dimension of the upstream side. As in this example, the upstream side of the second connecting segment 242 (e.g., referred to as the first sub-connecting segment 2421) is approximately a funnel structure, and the downstream side (e.g., referred to as the second sub-connecting segment 2422) is approximately a cylindrical structure. The aforementioned cross-sectional (radial) dimension of the connecting structure 24 being smaller than the cross-sectional dimension of the outlet valve should be understood in relation to the cross-section of the first connecting segment 241. Wherein, the cross-sectional dimension of the first sub-connected segment 2421 is not greater than 1 / 10 to 1 / 5 of the cross-sectional dimension of the second sub-connected segment 2422 (the maximum cross-sectional dimension of the second connected segment 242). For example, the cross-sectional dimension of the first sub-connected segment 2421 is not greater than 1 / 9 of the cross-sectional dimension of the second sub-connected segment 2422 (the maximum cross-sectional dimension of the second connected segment 242).

[0088] Obviously, the combination of the funnel structure and the cylindrical structure described above is only an exemplary description of the second connecting segment 242. Those skilled in the art can flexibly adjust it according to actual needs, such as including only the funnel structure.

[0089] Based on the above structure, in this example, taking the proportional valve assembly corresponding to the left and right burners as an example, when the intake valve 211 of the main valve 1 and the proportional valve assembly 2 is open, the firepower of the outer ring flame in the left / right burners can be controlled by adjusting the opening of the first outlet valve 221 and the second outlet valve 222. The firepower of the inner ring flame in the left / right burners can be controlled by adjusting the opening of the second outlet valve 222. When the intake valve 211 of the main valve 1 and the proportional valve assembly 2 is open, and both the first outlet valve 221 and the second outlet valve 222 are closed, the connection structure 24 ensures that the inner ring in the left / right burners still has a certain firepower. For the intermediate burner, the first outlet valve 221 can be blocked, or the proportional valve assembly corresponding to the first outlet valve can be adjusted according to actual needs, such as omitting the first outlet valve.

[0090] Based on the stove with the above structure, this application also provides a stove control method, which is mainly used to effectively suppress / eliminate the overflow state of the pot placed on the stove during the cooking process.

[0091] Main reference Figure 6 In one possible implementation, the method for controlling the stove includes the following steps:

[0092] S610. Determine if the pot is overflowing and check if the pot is currently overflowing. If yes, proceed to S620; otherwise, proceed to S650.

[0093] In this embodiment, the overflow status of the pot is determined by image data collected by an image detection component such as a camera assembly mounted on the camera. Exemplarily, the overflow status includes three types: not overflowing, completely overflowing, and about to overflow (rising). "Completely overflowing" and "about to overflowing" can be considered "yes," while "not overflowing" can be considered "no."

[0094] S620: If the pot has overflowed, obtain the current heat of the stove and determine whether the current heat is less than or equal to the preset heat. If yes, proceed to S630; otherwise, proceed to S640.

[0095] In this embodiment, the preset firepower is the minimum firepower setting in conventional firepower. In other words, if the current firepower is already at the minimum firepower setting in conventional firepower, then proceed to S630.

[0096] S630: Open the intake valve and close the exhaust valve so that gas reaches the burner of the stove via the connecting structure. In this case, the stove operates at the lowest heat setting based on the connecting structure.

[0097] In this embodiment, the specific operation of the minimum heat setting is as follows: the intake valve 211 of the main on / off valve 1 and the (left / right burner) proportional valve assembly 2 is opened, while the first outlet valve 221 and the second outlet valve 222 of the proportional valve assembly 2 are both closed. Thus, based on the connection structure 24, even when the first outlet valve 221 and the second outlet valve 222 of the corresponding proportional valve assembly 2 are closed, the inner ring of the burner still has a certain heat output. For example, the current cookware is placed... Figure 1 Above the left burner, indicating that the left burner is in operation.

[0098] Because the cross-sectional dimension of the connecting structure is much smaller than that of the second gas outlet, the burner's flame setting based on the connecting structure can be called the burner's minimum flame setting. The burner's flame can be adjusted within a larger range based on cooking needs by regulating the first / second gas outlet valve. In situations such as overflowing or impending overflow, the minimum flame setting created by the connecting structure ensures the stove's sustainability during cooking; specifically, it adapts to the current cooking needs without turning off the stove (not extinguishing the flame).

[0099] S640, Adjust the current firepower of the stove.

[0100] Adjusting the current heat should begin with lowering the heat. While adjusting the heat, the overflow status of the pot should be continuously determined based on the image data of the cookware. If overflow is effectively suppressed at a certain heat level, that heat level can be maintained, or the heat can be appropriately increased. If overflow has completely disappeared, increasing the heat can be attempted.

[0101] If the overflowing problem cannot be effectively suppressed even when the heat is lowered to the lowest preset heat setting, then the stove needs to be operated at the lowest heat setting based on the interconnected structure.

[0102] S650 continues to run according to the preset cooking logic until cooking is finished.

[0103] As can be seen, in the preferred embodiment of this application, the inlet valve of the proportional valve assembly can be connected to the main on / off valve, and the proportional valve assembly can be connected to the outer / inner ring gas path via the first / second outlet valve, thereby adjusting the proportion of gas output from the outer / inner ring gas path to the corresponding burner. By providing a connecting structure in the second passage between the inlet valve and the second outlet valve, the downstream side of the second outlet valve can still be connected to the inlet valve when the first / second outlet valve is closed. Accordingly, the burner can generate a very low heat setting. Specifically, when the main on / off valve is open / the inlet valve is open and the first / second outlet valve is closed, the gas from the main gas path can flow into the inner ring gas path via the inlet valve, the second passage, and the connecting structure. In extreme situations such as overflow or impending overflow, by operating the stove at the very low heat setting, it is possible to eliminate the extreme phenomena of overflow or impending overflow without extinguishing the flame.

[0104] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that, in order to achieve the effects of this application, different steps do not necessarily have to be executed in this order. They can be executed simultaneously or in other orders, and some steps can be added, replaced, or omitted. For example, the overflow state of the pot can be determined by the main control board of the stove, the main control board of the range hood, or the image data collected by the cloud based on the image detection component and then transmitted to the stove.

[0105] It should be noted that although the control method of the stove constructed in the above specific manner has been introduced as an example, those skilled in the art will understand that this application is not limited thereto. In fact, users can flexibly adjust the relevant steps and parameters in the steps according to actual application scenarios and other circumstances. For example, those skilled in the art can flexibly determine the specific types of overflow states in S610, the firepower adjustment method in S640, and the judgment criteria for whether the overflow state has been effectively suppressed, etc., according to actual needs.

[0106] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
