Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to a stove. Background Technology

[0002] With the improvement of living standards and the diversification of cooking methods, the variety of cookware in users' homes is becoming increasingly rich. Different sizes of cookware have different cooking heat requirements and heat transfer efficiencies. In contrast, traditional stoves often use standardized combustion structures and fixed firepower output modes, making it difficult to accurately match personalized firepower output according to the characteristics of different cookware.

[0003] Therefore, there is an urgent need for a stove to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this application is to provide a stove and a stove load matching control method, which can flexibly adjust the stove's firepower output according to the different pots and pans under different stove loads, thereby improving cooking efficiency while achieving efficient energy utilization.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a stove, comprising:

[0007] The panel has clearance holes;

[0008] A burner, a portion of which protrudes above the panel through the clearance hole, includes a burner base, a flame cap, an outer ring cap, and a baffle ring. The flame cap is mounted on the burner base and has multiple layers of flame outlet channels spaced apart along its height. The outer ring cap is fitted over the burner base and surrounds the flame cap, forming a receiving space with the burner base, the flame cap, and the outer ring cap. The baffle ring is located within the receiving space and fitted over the flame cap, and is movable up and down along the height of the flame cap. The burner base, the flame cap, the outer ring cap, and the baffle ring form an adjustment space.

[0009] A pot rack is installed on the panel and fitted over the burner; the pot rack is used to support the pot.

[0010] The control module includes a knob, a control unit, and a sensor. The knob is mounted on the panel and located on the outside of the pot rack. The sensor is mounted on the knob and is used to detect the angle between the line connecting the knob and the bottom of the pot located on the pot rack and the horizontal plane. The control unit can control the raising and lowering of the baffle ring according to the value detected by the sensor.

[0011] As an optional embodiment of the stove, the outer ring cover includes an outer peripheral wall and a cover portion connected to the top of the outer peripheral wall and extending to the inner side of the outer peripheral wall. The outer peripheral wall is fitted over the burner seat, and the cover portion is pressed on top of the burner cover.

[0012] As an optional feature of the stove, the inner sidewall of the outer peripheral wall has limiting surfaces spaced apart along its height direction, with two limiting surfaces arranged opposite to each other, and the air baffle ring rising and falling between the two limiting surfaces.

[0013] As an optional feature of the stove, the outer ring cover also includes an inner peripheral wall, which is connected to the cover portion and extends towards the bottom of the outer peripheral wall, and the inner peripheral wall can abut against the inner sidewall of the burner cap.

[0020] S203. Based on the relationship between θ, θ1, and θ2, determine the number n of fire exit channels that need to be closed.

[0021] S204. Determine the lifting stroke Sx of the air baffle ring according to n, where Sx is the distance between the air baffle ring in its current state and the bottom of the accommodating space.

[0022] As an optional solution to the stove load matching control method, in step S204, the lifting stroke Sx of the baffle ring is S1-n*S2, where S1 is the distance between the baffle ring at its maximum stroke and the bottom of the accommodating space, and when the baffle ring is at its maximum stroke, all the flame outlet channels are in the open state; S2 is the distance between each layer of flame outlet channels.

[0054] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0055] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0056] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0057] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0058] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0059] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0060] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0061] Figure 1 A schematic diagram of the structure of the stove 100 provided in an embodiment of this application is shown. Figure 1As shown, the stove 100 provided in this application includes a bottom shell 101, a panel 102, a burner 103, and a pot rack 104. The bottom shell 101 is mounted on the stovetop. The panel 102 is mounted on the bottom shell 101 and serves as the exterior surface of the stove 100, enhancing its aesthetics. The panel 102 has a clearance hole through which the burner 103 passes. A portion of the burner 103 is mounted on the bottom shell 101 through the clearance hole, and a portion of the burner 103 protrudes above the panel 102 through the clearance hole. The pot rack 104 is placed on the panel 102 and surrounds the outer periphery of the burner 103. The pot rack 104 is used to place the pot 200.

[0062] It is understood that the burner 103 and the pot support 104 are arranged in a group. In this embodiment, there are two burners 103 and two pot supports 104. In another embodiment, the number of burners 103 and two pot supports 104 can be one, three, four, or any other number, and can be designed according to needs, without limitation here.

[0063] To facilitate control of the heat level of the cooktop 100, the cooktop 100 provided in this application also includes a control module. The control module allows users to manually control the heat level of the cooktop 100, and can also automatically control the heat level of the cooktop 100 to improve the user's cooking experience. For example, the control module includes a control unit and a knob 105. The knob 105 is mounted on the panel 102 for easy manual operation of the cooktop 100. The control unit is communicatively connected to the knob 105, and can control the flame size of the burner 103 according to the state of the knob 105. Specifically, the control unit can control the heat level of the burner 103 by controlling the gas supply, or by controlling the flame output of the burner 103.

[0064] Figure 2 A partial cross-sectional view of a stove 100 provided in an embodiment of this application is shown. Figure 2 As shown, the burner 103 includes a burner head 1, a flame distribution seat 2, a flame cover 3, and an outer ring cover 4. The flame distribution seat 2 is installed on the burner head 1, the flame cover 3 is installed on the flame distribution seat 2, the flame cover 3 has a flame outlet channel, and the outer ring cover 4 is sleeved on the outside of the flame distribution seat 2 and surrounds the outside of the flame cover 3. The outer walls of the flame distribution seat 2, the outer ring cover 4, and the flame cover 3 form an accommodating space.

[0065] During the operation of the stove 100, the mixed gas (a mixture of gas and air) supplied by the burner 1 first enters the containment space, and then enters the interior of the burner 3 through the flame outlet channel of the burner 3 for combustion, so as to heat and cook the pot 200 on the pot rack 104.

[0066] Figure 3 A cross-sectional schematic diagram of the burner 103 provided in an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of the burner head 1 provided in an embodiment of this application is shown. Figure 5 A cross-sectional schematic diagram of the flame holder 2, flame cap 3, and outer ring cap 4 provided in an embodiment of this application is shown. Figures 3 to 5 As shown, the burner head 1 includes a base 11 and an inner ignition channel 12 and an outer ignition channel 13 installed on the base 11. Multiple outer ignition channels 13 surround the inner ignition channel 12, and the height of the inner ignition channel 12 is higher than the height of the outer ignition channel 13. The burner seat 2 is placed on the outer ignition channel 13 and sleeved outside the inner ignition channel 12. The burner cap 3 is installed on the burner seat 2 and sleeved outside the inner ignition channel 12. The burner cap 3 has multiple layers of flame outlet channels 30 spaced apart along its height. The burner seat 2, the burner cap 3, and the outer ring cap 4 form a receiving space. The mixed gas supplied by the outer ignition channel 13 can enter the receiving space from the bottom of the burner seat 2, and then enter the interior of the burner cap 3 for combustion through the receiving space and the flame outlet channels 30.

[0067] In this embodiment, there are four external ignition channels 13, which are evenly spaced around the periphery of the inner ignition channel 12. In other embodiments, the number of external ignition channels 13 can be any number, such as two, three, or five, and can be designed according to specific needs.

[0068] In order to achieve automatic control of the firepower of the stove 100, the control module also includes a sensor 106, which is mounted on the knob 105. The sensor 106 is used to detect the angle between the line connecting it and the bottom of the pot 200 located on the pot rack 104 and the horizontal plane. The control unit can control the firepower of the burner 103 according to the value detected by the sensor 106.

[0069] like Figure 5 Combination Figure 3 As shown, the ignition distribution seat 2 includes a seat body 21 and an inner protruding ring 22 and an outer protruding ring 23 protruding from the seat body 21. The seat body 21 is placed on the outer ignition channel 13 to ensure the stability of the ignition distribution seat 2. The outer protruding ring 23 is arranged around the inner protruding ring 22 and spaced apart from the inner protruding ring 22. The flame cap 3 is sleeved on the outer side of the inner protruding ring 22 so that the flame cap 3 and the outer ring cap 4 can be installed on the ignition distribution seat 2. In addition, part of the outer ring cap 4 is sleeved on the outer protruding ring 23, and the other part of the outer ring cap 4 is pressed on the top of the flame cap 3, so that the ignition distribution seat 2, the outer ring cap 4, and the flame cap 3 form the aforementioned receiving space.

[0070] Understandably, in order to facilitate the smooth entry of the mixed gas in the external ignition channel 13 of the burner head 1 into the receiving space, a vent (not shown in the figure) is provided on the base body 21 at a position corresponding to the external ignition channel 13. This vent is precisely aligned with the outlet of the external ignition channel 13 to ensure that the mixed gas in the external ignition channel 13 enters the receiving space without leakage through the vent, thereby reducing gas leakage and improving the safety of the stove 100.

[0071] The outer ring cover 4 includes an outer peripheral wall 41 and a cover portion 42 connected to the top of the outer peripheral wall 41 and extending to the inner side of the outer peripheral wall 41. The outer peripheral wall 41 is fitted and supported on the outer protruding ring 23, and the cover portion 42 is pressed on the top of the flame cover 3, so that the outer side walls of the flame distribution seat 2, the outer ring cover 4 and the flame cover 3 form the above-mentioned containment space, thereby avoiding or reducing the leakage of the mixed gas in the containment space.

[0072] The inner sidewall of the outer peripheral wall 41 also has a limiting surface 411. The outer peripheral wall 41 is sleeved on the outer convex ring 23, and the limiting surface 411 abuts against the end face of the outer convex ring 23. The limiting installation of the outer ring cover 4 is achieved through the abutment between the end face of the outer convex ring 23 of the fire distribution seat 2 and the limiting surface 411 of the outer peripheral wall 41 of the outer ring cover 4, while ensuring the stability of the outer ring cover 4.

[0073] Furthermore, the outer ring cover 4 also includes an inner peripheral wall 43, which is connected to the cover portion 42 and extends towards the bottom of the outer peripheral wall 41. The inner peripheral wall 43 can abut against the inner sidewall of the flame cap 3 to achieve the limiting installation of the outer ring cover 4. In other words, the abutment between the end face of the outer convex ring 23 and the limiting surface 411 of the outer ring cover 4 achieves the limiting of the outer ring cover 4 in the vertical direction, and the abutment between the inner sidewall of the flame cap 3 and the inner peripheral wall 43 of the outer ring cover 4 achieves the limiting of the outer ring cover 4 in the radial direction, thereby improving the stability of the installation of the outer ring cover 4.

[0074] The burner 103 also includes a gas-blocking mechanism, which is used to keep some or all of the multi-layer flame outlet channels 30 in an open or closed state to adjust the flame output of the burner cap 3, thereby adjusting the flame intensity of the burner 103.

[0075] In this embodiment, the gas-blocking mechanism includes a gas-blocking ring 51 and a driver. The driver is installed on the ignition base 2 and is used to drive the gas-blocking ring 51 to move up and down along the height direction of the flame cap 3. The gas-blocking ring 51 is sleeved on the outside of the flame cap 3, and its inner sidewall can fit against the outer sidewall of the flame cap 3. Its outer sidewall can fit against the inner sidewall of the outer ring cover 4 (specifically, the inner sidewall of the outer peripheral wall 41 of the outer ring cover 4), thereby forming an adjustment space by the ignition base 2, the flame cap 3, the outer ring cover 4, and the gas-blocking ring 51. The mixed gas enters the flame outlet channel 30 through the adjustment space and finally enters the flame cap 3 for combustion. It should be noted that the adjustment space is the space below the aforementioned containment space. Ideally, the mixed gas can only enter the adjustment space and cannot enter the space above the adjustment space by passing through the gas-blocking ring 51. Furthermore, the flame outlet channel 30 located below the baffle ring 51 (i.e., the flame outlet channel 30 located within the adjustment space) can receive the mixed gas, while the flame outlet channel 30 located above the baffle ring 51 cannot receive the mixed gas. Thus, by driving the baffle ring 51 to rise and fall, the height of the adjustment space can be changed, thereby adjusting the number of layers of the flame outlet channel 30 that can supply the mixed gas, and thus adjusting the flame output of the burner cap 3, i.e., the firepower of the burner 103.

[0076] To limit the lifting and lowering stroke of the baffle ring 51, the inner sidewall of the outer peripheral wall 41 has limiting surfaces 412 spaced apart along its height direction. The two limiting surfaces 412 are positioned opposite each other, and the baffle ring 51 rises and falls between them. It should be noted that when the baffle ring 51 abuts against the lower limiting surface 412, the lowest flame outlet channel 30 of the burner cap 3 can receive the mixed gas; when the baffle ring 51 abuts against the upper limiting surface 412, all flame outlet channels 30 of the burner cap 3 can receive the mixed gas. Each time the baffle ring 51 descends the height of one flame outlet channel 30, it closes one flame outlet channel 30; each time the baffle ring 51 rises the height of one flame outlet channel 30, it opens one flame outlet channel 30.

[0077] The air baffle mechanism also includes a telescopic component 52, one end of which is connected to the ignition base 2, and the other end is connected to the air baffle ring 51. The telescopic component 52 can extend and retract as the air baffle ring 51 rises and falls. In addition, the telescopic component 52 can be a telescopic rod, a pivot rod, or a spring, or other structural components with telescopic functions, and there are no restrictions on this.

[0078] Figure 6 A schematic diagram of the structure of the telescopic member 52 provided in an embodiment of this application is shown. Figure 6 As shown, multiple telescopic components 52 are arranged at intervals along the circumference of the air baffle ring 51 to ensure the stability of the air baffle ring 51 during lifting and lowering. It can be understood that the number of telescopic components 52 can be any number, such as two, three, four, five, six, or seven, and can be designed according to specific needs, without any restrictions here.

[0079] Figure 7 A schematic diagram of the structure of the flame cover 3 provided in an embodiment of this application is shown. Figure 7 As shown, the flame cap 3 is composed of multiple first stacked pieces 31 and multiple second stacked pieces 32 stacked alternately. The outermost layer of the flame cap 3 is always a second stacked piece 32. Both the first stacked pieces 31 and the second stacked pieces 32 are annular, and adjacent first stacked pieces 31 and second stacked pieces 32 cooperate to form a flame outlet channel 30. In addition, the first stacked pieces 31 are high-temperature resistant metal sheets; the second stacked pieces 32 are high-temperature resistant metal sheets, for example, both the first stacked pieces 31 and the second stacked pieces 32 are stainless steel sheets.

[0080] It should be noted that, Figure 7 The first stacked sheet 31 and the second stacked sheet 32 ​​shown are both annular. In other embodiments, the first stacked sheet 31 and the second stacked sheet 32 ​​can also be annular in other shapes, such as elliptical annular or regular octagonal annular, as long as the first stacked sheet 31 and the second stacked sheet 32 ​​are sheet-like structures with a through hole in the middle, which is not limited here.

[0081] In this embodiment, there are six first stacked pieces 31 and seven second stacked pieces 32. The six first stacked pieces 31 and the seven second stacked pieces 32 are stacked alternately to form six layers of fire outlet channels 30. In other embodiments, the number of first stacked pieces 31 can be any number, such as three, four, five, seven, eight, nine, or ten, and can be designed as needed. There are no restrictions on this.

[0082] Figure 8 This illustration shows a schematic diagram of the structure of the first stacked piece 31 and the second stacked piece 32 in the flame cover 3 provided in an embodiment of this application. Figure 8 Combination Figure 7 As shown, the first lamination 31 has a recess 3111 extending in the radial direction of the first lamination 31, and a plurality of recesses 3111 are arranged at intervals along the periphery of the first lamination 31, and a groove 3112 is formed between two adjacent recesses 3111; the surface of the second lamination 32 can be in contact with the surface of the first lamination 31; the second lamination 32 in contact with the outer surface of the recess 3111 and the single groove 3112 cooperate to form a single flame outlet 30a extending in the radial direction of the first lamination 31, and all flame outlets 30a in the same layer constitute a flame outlet channel 30.

[0083] Among them, the end of the flame outlet 30a located inside the burner cap 3 is the gas outlet end, and the end located outside the burner cap 3 is the gas inlet end. When the burner 103 does not have a baffle ring 51, the mixed gas enters the containment space (when the burner 103 has a baffle ring 51, the mixed gas enters the regulating space). Then, the mixed gas in the containment space can enter the flame outlet 30a through the gas inlet end of each flame outlet 30a, and finally enter the interior of the burner cap 3 from the gas outlet end of the flame outlet 30a for combustion.

[0084] In this embodiment, multiple recesses 311 are arranged at intervals around the center of the first stack 31 to facilitate the processing and shaping of the first stack 31 and to improve the processing accuracy of the first stack 31.

[0085] The first stack 31 includes an inner ring region 311 and an outer edge region 312 surrounding the inner ring region 311. Multiple recesses 3111 are evenly spaced in the inner ring region 311 with the center of the first stack 31 as the center. The surface of the outer edge region 312 can fit against the surface of the second stack 32. This arrangement allows the outer edge of each flame outlet channel 30 to have a buffer channel formed by the outer edge region 312 of the first stack 31 and the second stack 32. The mixed gas in the receiving space (or regulating space) first enters the buffer channel and then enters the interior of the flame cap 3 through each flame outlet 30a, thereby increasing the air intake of each flame outlet 30a.

[0086] The second stack 32 is flat, and the outer edge area 312 is flat, so as to ensure that the first stack 31 and the second stack 32 are stably attached, thereby forming a stable flame outlet channel 30 and making each flame outlet hole 30a of each layer of flame outlet channel 30 independent of each other, realizing the diversion and diversion of the mixed gas, and ensuring that the mixed gas flows into the flame cap 3 in an orderly manner.

[0087] The centerline of the ignition port 30a extends along the radial direction of the burner cap 3 to shorten the path of the ignition port 30a and improve the intake efficiency of the mixed gas entering the interior of the burner cap 3.

[0088] The flow area of ​​the flame outlet 30a gradually decreases from its inlet end to its outlet end. Because the inlet end of the flame outlet 30a has a larger flow area, more mixed gas enters the flame outlet 30a. Conversely, the outlet end of the flame outlet 30a has a smaller flow area, which accelerates the flow of the mixed gas within the flame outlet 30a. This results in a higher flow velocity for the mixed gas entering the burner cap 3, increasing the collision effect of the mixed gas exiting from different flame outlets 30a, further homogenizing the air and fuel gas, and improving combustion efficiency.

[0089] The cross-sectional shape of the flame outlet 30a can be an isosceles trapezoid. In this case, the flame outlet 30a can be a prism structure with a quadrilateral longitudinal section or a conical structure with a roughly circular longitudinal section. Examples will not be given here.

Figure 10 A schematic diagram of the layout of the sensor 106 of the cooktop 100 provided in this application is shown. Figure 11 A schematic flowchart of a stove load matching control method provided in an embodiment of this application is shown. Figures 9 to 11 As shown, based on the aforementioned stove 100, the stove load matching control method provided in this application includes the following steps:

[0091] S100, start the stove 100.

[0092] S200, Load Matching: Based on the relationship between the angle θ between the line connecting the bottom of sensor 106 and the bottom of cookware 200 and the horizontal plane, the angle θ1 between the line connecting the top center point of sensor 106 and the pot rack 104 and the horizontal plane, and the angle θ2 between the line connecting the top center point of sensor 106 and the burner 103 and the horizontal plane, determine the number n of the flame outlet channels 30 that need to be closed.

[0093] S300: Determine if the time during which the user has not operated the stove 100 is greater than T2; if yes, execute S400; if no, execute S200.

[0094] T2 can be any value between 25s and 45s, such as 25s, 30s, 35s, and 40s.

[0095] S400 and stove 100 remain at their current settings.

[0096] S500: Determine whether sensor 106 has detected cookware 200; if yes, cookware 100 continues to run and S200 is executed; if no, S600 is executed.

[0097] S600, Stove 100 off, cooking finished.

[0098] The stove load matching control method provided in this application can obtain relevant information about the size of the cookware 200 based on the relationship between θ, θ1 and θ2, and then match the corresponding fire load according to the size of the cookware 200, thereby determining the number n of the flame channels 30 that need to be closed, which can meet the needs of balancing energy saving and cooking efficiency.

[0099] Figure 12 Another schematic flowchart of the stove load matching control method provided in this application embodiment is shown. Figure 12 As shown, step S200 includes the following steps:

[0100] Step S200 includes the following steps:

[0101] S201. Determine whether the time the stove 100 has been in the current setting is greater than T1; if yes, execute S202; if no, it indicates that the user has made a manual adjustment.

[0102] T1 can be any value between 5s and 8s, such as 5s, 6s, 7s, or 8s.

[0103] S202. Start sensor 106 and acquire parameters θ, θ1 and θ2.

[0104] The value of θ is directly related to the size of the cookware 200 and the shape of its bottom. Therefore, θ is detected by the sensor 106 in real time and transmitted to the control module. θ1 and θ2 are related to the top diameter of the burner 103 and the top diameter of the pot rack 104. Since the top diameter of the burner 103 and the top diameter of the pot rack 104 are constant values, θ1 and θ2 can be input into the control module in the form of preset parameters measured manually, so that the control module can call them when making decisions.

[0105] S203. Based on the relationship between θ, θ1 and θ2, determine the number n of the fire outlet channels 30 that need to be closed.

[0106]

[0107] S204. Determine the lifting stroke Sx of the air baffle ring 51 according to n. Sx is the distance between the air baffle ring 51 in its current state and the bottom of the accommodating space.

[0108] The lifting stroke Sx of the baffle ring 51 is calculated as S1 - n*S2, where S1 is the distance between the baffle ring 51 at its maximum stroke and the bottom of the accommodating space, and all fire outlet channels 30 are open when the baffle ring 51 is at its maximum stroke. S2 is the distance between the fire outlet channels 30 on each floor. Both S1 and S2 can be manually measured and input into the control module as preset parameters for the control module to use when making decisions.

[0109] The cooktop load matching control method provided in this application can accurately match the load requirements of various cookware 200 according to the different cookware 200 used by the user, thereby achieving energy saving and emission reduction, improving the user's cooking experience, reducing cooking problems caused by human error, and providing more personalized and intelligent cooking services.

[0110] The following example will be used to further illustrate the stove load matching control method provided in this application.

[0111] In this example, the stove 100 has 6 layers of flame channels (30 layers). Before the stove 100 leaves the factory, it needs to be set up to match different flame loads according to the diameter of different cookware 200. For example, different flame loads with 30 layers of flame channels can be set based on cookware 200 with diameters of 38cm, 35cm, 32cm, 29cm, and 26cm. For example, when the diameter of the cookware 200 is greater than 38cm, the number of flame layers in the flame channel 30 is 6; when the diameter of the cookware 200 is greater than 35cm and less than or equal to 38cm, the number of flame layers in the flame channel 30 is 5; when the diameter of the cookware 200 is greater than 32cm and less than or equal to 35cm, the number of flame layers in the flame channel 30 is 4; when the diameter of the cookware 200 is greater than 29cm and less than or equal to 32cm, the number of flame layers in the flame channel 30 is 3; when the diameter of the cookware 200 is greater than 26cm and less than or equal to 29cm, the number of flame layers in the flame channel 30 is 2; and when the diameter of the cookware 200 is less than or equal to 26cm, the number of flame layers in the flame channel 30 is 1.

[0112] In the load control method for the stove 100 based on the above-mentioned stove 100, the number n of the flame outlet channels 30 that need to be closed is determined according to the relationship between θ, θ1, and θ2, specifically as follows:
