[0064] Figure 1 FIG. 1 shows a schematic diagram of the structure of a stove 100 provided in an embodiment of the present application. Figure 1 As shown, the stove 100 provided in the present application includes a bottom shell 101, a panel 102, a burner 103 and a pot rack 104, the bottom shell 101 is installed on the stove; the panel 102 is installed on the bottom shell 101 and serves as the appearance surface of the stove 100, thereby improving the aesthetics of the stove 100; the panel 102 has an avoidance hole for the burner 103 to pass through, part of the burner 103 is installed on the bottom shell 101 through the avoidance hole, and part of the burner 103 protrudes above the panel 102 through the avoidance hole; the pot rack 104 is placed on the panel 102 and is arranged around the outer periphery of the burner 103, and the pot rack 104 is used to place the pot 200.

[0065] It is understandable that the burner 103 and the pot rack 104 are arranged in groups. In this embodiment, the number of the burner 103 and the pot rack 104 are both two. In another embodiment, the number of the burner 103 and the pot rack 104 can also be one, three, four, or any other number, which can be specifically designed according to needs and is not limited here.

[0066] In order to facilitate the control of the fire power level of the stove 100, the stove 100 provided in the present application also includes a control module, which can facilitate the user to manually control the fire power level of the stove 100, and can also automatically control the fire power level of the stove 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 installed on the panel 102, and is convenient for the user to manually operate the stove 100. The control unit is connected to the knob 105 for communication, and the control unit can control the fire size of the burner 103 according to the state of the knob 105. Specifically, the control unit can control the fire power of the burner 103 by controlling the supply of gas, and can also control the fire power of the burner 103 by controlling the fire amount of the burner 103.

[0067] Figure 2FIG. 1 is a partial cross-sectional schematic diagram of a stove 100 provided in an embodiment of the present application. Figure 2 As shown, the burner 103 includes a burner head 1, a fire divider seat 2, a fire cover 3 and an outer ring cover 4. The fire divider seat 2 is installed on the burner head 1, and the fire cover 3 is installed on the fire divider seat 2. The fire cover 3 has a fire outlet channel. The outer ring cover 4 is sleeved on the outside of the fire divider seat 2 and is arranged around the outside of the fire cover 3. The outer side walls of the fire divider seat 2, the outer ring cover 4 and the fire cover 3 are arranged to form a accommodating space.

[0068] During operation of the cooker 100 , the mixed gas (a mixture of gas and air) supplied by the burner 1 first enters the accommodating space, and then enters the interior of the fire cover 3 through the fire outlet passage of the fire cover 3 to be burned, so as to heat and cook the pot 200 on the pot rack 104 .

[0069] Figure 3 A cross-sectional schematic diagram of a burner 103 provided in an embodiment of the present application is shown. Figure 4 A schematic structural diagram of a furnace head 1 provided in an embodiment of the present application is shown. Figure 5 FIG. 2 shows a cross-sectional schematic diagram of the fire distribution seat 2, the fire cover 3 and the outer ring cover 4 provided in the embodiment of the present application. 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. A plurality of outer ignition channels 13 are arranged around the inner ignition channel 12, and the height of the inner ignition channel 12 is higher than that of the outer ignition channels 13. The fire-distributing seat 2 is placed on the outer ignition channel 13 and sleeved outside the inner ignition channel 12. The fire cover 3 is installed on the fire-distributing seat 2 and sleeved outside the inner ignition channel 12. The fire cover 3 has multiple layers of fire outlet channels 30 arranged at intervals along its height. The fire-distributing seat 2, the fire cover 3 and the outer ring cover 4 are arranged to form a receiving space. The mixed gas supplied by the outer ignition channel 13 can enter the receiving space from the bottom of the fire-distributing seat 2, and then enter the interior of the fire cover 3 through the receiving space and the fire outlet channels 30 in sequence for combustion.

[0070] In this embodiment, the number of the outer ignition channels 13 is four, and the four outer ignition channels 13 are evenly spaced and arranged around the inner ignition channel 12. In other embodiments, the number of the outer ignition channels 13 can also be any number such as two, three, or five, which can be specifically designed according to needs.

[0071] In order to realize automatic control of the fire power of the stove 100, Figure 4 Combination Figure 2 As shown, the control module also includes a sensor 106, which is installed on the burner 1. The sensor 106 is used to detect the distance between it and the bottom of the pot 200 located on the pot rack 104. The control unit can control the firepower of the burner 103 according to the value detected by the sensor 106.

[0072] Continue as Figure 5 Combination Figure 3 As shown, the fire-spreading seat 2 includes a seat body 21 and an inner convex ring 22 and an outer convex ring 23 convexly arranged on the seat body 21. The seat body 21 is placed on the outer ignition channel 13 to ensure the stability of the fire-spreading seat 2; the outer convex ring 23 is arranged around the outer periphery of the inner convex ring 22 and is spaced from the inner convex ring 22, and the fire cover 3 is sleeved outside the inner convex ring 22, so that the fire cover 3 and the outer ring cover 4 can be installed on the fire-spreading seat 2. In addition, part of the outer ring cover 4 is sleeved outside the outer convex ring 23, and the other part of the outer ring cover 4 is pressed on the top of the fire cover 3, so that the fire-spreading seat 2, the outer ring cover 4 and the fire cover 3 are surrounded to form the above-mentioned accommodation space.

[0073] It is understandable that, in order to facilitate the mixed gas in the external ignition channel 13 of the burner head 1 to smoothly enter the accommodation space, a vent hole (not shown in the figure) is provided at a position of the seat body 21 corresponding to the external ignition channel 13. The vent hole is exactly connected to the outlet of the external ignition channel 13 to ensure that the mixed gas in the external ignition channel 13 enters the accommodation space through the vent hole without leakage, which can reduce gas leakage and improve the safety of the stove 100.

[0074] 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 toward the inner side of the outer peripheral wall 41. The outer peripheral wall 41 is sleeved and supported on the outer convex ring 23, and the cover portion 42 is pressed on the top of the fire cover 3, so that the outer side walls of the fire distributor 2, the outer ring cover 4 and the fire cover 3 are surrounded to form the above-mentioned accommodating space, thereby avoiding or reducing the leakage of the mixed gas in the accommodating space.

[0075] The inner side wall of the outer peripheral wall 41 also has a limiting surface 411. The outer peripheral wall 41 is sleeved outside the outer convex ring 23, and the limiting surface 411 abuts against the end surface of the outer convex ring 23. The limiting installation of the outer ring cover 4 is achieved through the abutment between the end surface of the outer convex ring 23 of the ignition 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.

[0076] Furthermore, the outer ring cover 4 also includes an inner peripheral wall 43, which is connected to the cover portion 42 and extends toward the bottom direction of the outer peripheral wall 41, and the inner peripheral wall 43 can abut against the inner side wall of the fire cover 3 to achieve the limited installation of the outer ring cover 4. In other words, the outer ring cover 4 is limited in the up and down directions by the abutment and cooperation between the end face of the outer convex ring 23 and the limiting surface 411 of the outer ring cover 4, and the outer ring cover 4 is limited in the radial direction by the abutment and cooperation between the inner side wall of the fire cover 3 and the inner peripheral wall 43 of the outer ring cover 4, thereby improving the stability of the installation of the outer ring cover 4.

[0077] The burner 103 also includes an air blocking mechanism, which is used to open or close part or all of the multi-layer fire outlet channels 30 to adjust the fire output of the fire cover 3 and further adjust the fire power of the burner 103.

[0078] In this embodiment, the air blocking mechanism includes an air blocking ring 51 and a driver, the driver is installed on the fire distributor seat 2 and is used to drive the air blocking ring 51 to move up and down along the height direction of the fire cover 3; the air blocking ring 51 is sleeved outside the fire cover 3, and the inner wall of the air blocking ring 51 can fit with the outer wall of the fire cover 3, and its outer wall can fit with the inner wall of the outer ring cover 4 (specifically, the inner wall of the outer peripheral wall 41 of the outer ring cover 4), so that the fire distributor seat 2, the fire cover 3, the outer ring cover 4 and the air blocking ring 51 are surrounded to form an adjustment space, and the mixed gas enters the fire outlet channel 30 through the adjustment space, and finally enters the fire cover 3 for combustion. It should be noted that the adjustment space is the space below the above-mentioned accommodating space. Under ideal conditions, the mixed gas can only enter the adjustment space, but cannot pass through the air blocking ring 51 to enter the space above the adjustment space. In addition, the fire outlet channel 30 located below the air blocking ring 51 (that is, the fire outlet channel 30 located in the regulating space) can receive the mixed gas, while the fire outlet channel 30 located above the air blocking ring 51 cannot receive the mixed gas. Therefore, the height of the regulating space can be changed by driving the air blocking ring 51 to rise and fall, thereby adjusting the number of layers of the fire outlet channels 30 that can supply the mixed gas, and then adjusting the fire output of the fire cover 3, that is, the fire power of the burner 103.

[0079] In order to limit the lifting stroke of the air-blocking ring 51, the inner side wall of the outer peripheral wall 41 has limit baffles 412 arranged at intervals along its height direction, and the two limit baffles 412 are arranged opposite to each other, and the air-blocking ring 51 rises and falls between the two limit baffles 412. It should be noted that when the air-blocking ring 51 abuts against the limit baffle 412 located below, the fire outlet channel 30 at the bottom layer of the fire cover 3 can receive the mixed gas; when the air-blocking ring 51 abuts against the limit baffle 412 located above, all the fire outlet channels 30 of the fire cover 3 can receive the mixed gas. Each time the air-blocking ring 51 descends the height of one layer of the fire outlet channel 30, one layer of the fire outlet channel 30 is closed; each time the air-blocking ring 51 rises the height of one layer of the fire outlet channel 30, one layer of the fire outlet channel 30 is opened.

[0080] The gas blocking mechanism also includes a telescopic member 52, one end of which is connected to the fire-distributing seat 2, and the other end of which is connected to the gas blocking ring 51. The telescopic member 52 can be extended and retracted with the rise and fall of the gas blocking ring 51. In addition, the telescopic member 52 can be a structural member with a telescopic function such as a telescopic rod, a pivot connecting rod or a spring, which is not limited here.

[0081] Figure 6 FIG. 5 shows a schematic diagram of the structure of the telescopic member 52 provided in an embodiment of the present application. Figure 6 As shown, a plurality of telescopic members 52 are arranged at intervals along the circumference of the air retaining ring 51 to ensure the stability of the lifting of the air retaining ring 51. It is understandable that the number of the telescopic members 52 can be any number such as two, three, four, five, six, seven, etc., and can be specifically designed according to needs, and is not limited here.

[0082] Figure 7 The structure diagram of the fire cover 3 provided in the embodiment of the present application is shown. Figure 7 As shown, the fire cover 3 is formed by alternately stacking a plurality of first laminates 31 and a plurality of second laminates 32, the outermost layer of the fire cover 3 is the second laminate 32, the first laminate 31 and the second laminate 32 are both annular, and adjacent first laminates 31 and second laminates 32 cooperate to form a layer of fire outlet channel 30. In addition, the first laminate 31 is a high temperature resistant metal sheet; the second laminate 32 is a high temperature resistant metal sheet, for example, the first laminate 31 and the second laminate 32 are both stainless steel sheets.

[0083] It should be noted that Figure 7 The first laminate 31 and the second laminate 32 shown are both in the shape of circular rings. In other embodiments, the first laminate 31 and the second laminate 32 may also be in the shape of rings of other shapes, such as an elliptical ring, a regular octagonal ring, etc., as long as the first laminate 31 and the second laminate 32 are sheet structures with through holes in the middle, there is no limitation here.

[0084] In this embodiment, the number of the first laminations 31 is six, the number of the second laminations 32 is seven, and the six first laminations 31 and the seven second laminations 32 are alternately stacked to form a six-layer fire outlet channel 30. In other embodiments, the number of the first laminations 31 can also be three, four, five, seven, eight, nine, ten, or any other number, which can be designed according to needs and is not limited here.

[0085] Figure 8 FIG. 2 shows a schematic diagram of the structure of the first laminate 31 and the second laminate 32 in the fire cover 3 provided in the embodiment of the present application. Figure 8 Combination Figure 7 As shown, the first laminate 31 has a recessed portion 3111 extending in the radial direction of the first laminate 31, and a plurality of recessed portions 3111 are arranged at intervals along the circumference of the first laminate 31, and a groove 3112 is formed between two adjacent recessed portions 3111; the surface of the second laminate 32 can be fitted with the surface of the first laminate 31; the second laminate 32 fitted with the outer surface of the recessed portion 3111 cooperates with the single groove 3112 to form a single fire hole 30a extending in the radial direction of the first laminate 31, and all the fire holes 30a on the same layer form a layer of fire channel 30.

[0086] Among them, the end of the fire hole 30a located on the inner side of the fire cover 3 is the gas outlet end, and the end of the fire hole 30a located on the outer side of the fire cover 3 is the gas inlet end. When the burner 103 does not have an air baffle ring 51, the mixed gas enters the accommodating space (when the burner 103 has an air baffle ring 51, the mixed gas enters the regulating space), and then the mixed gas in the accommodating space can enter the fire hole 30a through the gas inlet end of each fire hole 30a, and finally enter the inside of the fire cover 3 from the gas outlet end of the fire hole 30a for combustion.

[0087] In this embodiment, a plurality of recessed portions 311 are arranged at intervals with the center of the first laminate 31 as the center of the circle, so as to facilitate the processing and forming of the first laminate 31 and improve the processing accuracy of the first laminate 31 .

[0088] The first laminate 31 includes an inner ring area 311 and an outer edge area 312 arranged around the inner ring area 311. A plurality of recessed portions 3111 are evenly spaced in the inner ring area 311 with the center of the first laminate 31 as the center of the circle. The surface of the outer edge area 312 can be in contact with the surface of the second laminate 32. In this way, the outer edge of each layer of the fire outlet channel 30 has a buffer channel formed by the outer edge area 312 of the first laminate 31 and the second laminate 32, that is, the mixed gas in the accommodating space (or regulating space) first enters the buffer channel and then enters the interior of the fire cover 3 through each fire outlet hole 30a, thereby increasing the air intake of each fire outlet hole 30a.

[0089] The second laminate 32 is flat, and the outer edge area 312 is flat to ensure that the first laminate 31 and the second laminate 32 are stably fitted, thereby forming a fire outlet channel 30 with stable drainage, and making the fire outlet holes 30a of each layer of the fire outlet channel 30 independent of each other, realizing the diversion and drainage of the mixed gas, and ensuring that the mixed gas flows into the fire cover 3 in an orderly manner.

[0090] The center line of the fire outlet hole 30 a extends along the radial direction of the fire cover 3 to shorten the path of the fire outlet hole 30 a and improve the intake efficiency of the mixed gas into the interior of the fire cover 3 .

[0091] The flow area of ​​the fire hole 30a gradually decreases from its air inlet end to its air outlet end. Since the flow area of ​​the air inlet end of the fire hole 30a is larger, more mixed gas enters the fire hole 30a, while the flow area of ​​the air outlet end of the fire hole 30a is smaller, so that the mixed gas in the fire hole 30a can flow faster, so that the mixed gas entering the fire cover 3 has a higher flow rate, and the collision effect of the mixed gas coming out of different fire holes 30a is increased, so that the air and gas are further mixed evenly, and the combustion efficiency is improved.

[0092] The cross-sectional shape of the fire outlet 30a can be an isosceles trapezoid. At this time, the fire outlet 30a can be a prism-shaped structure with a quadrilateral longitudinal section, or a conical structure with a roughly circular longitudinal section, which will not be described one by one here.

[0093] Fig. 9 A schematic diagram showing relevant parameters of the cooker 100 provided in the present application is shown. Fig.10 A flow chart of a method for controlling the cooker load matching provided by an embodiment of the present application is shown. Figures 9 and 10As shown, the sensor 106 of the stove 100 is installed on the burner 1, and the sensor 106 is used to detect the distance L between the sensor 106 and the bottom of the pot 200 located on the pot rack 104. The control unit can control the fire power of the burner 103 according to the value detected by the sensor 106. Based on the stove 100, the stove load matching control method provided by the present application includes the following steps:

[0094] S100 , starting the cooker 100 .

[0095] S200, load matching: according to the relationship between the distance L between the sensor 106 and the bottom of the pot 200, the distance L1 between the sensor 106 and the top of the pot rack 104, and the distance L2 between the sensor 106 and the top of the burner 103, determine the number of layers n of the fire outlet channel 30 that needs to be closed.

[0096] S300, determining whether the time during which the user has not operated the cooker 100 is greater than T2; if so, executing S400; if not, executing S200.

[0097] T2 may be any value between 25s and 45s, such as 25s, 30s, 35s, or 40s.

[0098] S400: The cooker 100 maintains the current gear position unchanged.

[0099] S500, determining whether the sensor 106 detects the cooker 200, if so, the cooker 100 keeps running and executes S200; if not, executes S600.

[0100] S600: The cooker 100 is turned off and cooking is finished.

[0101] The stove load matching control method provided in the present application can determine the relevant information of the size of the pot 200 according to the relationship between L, L1 and L2, and then match the corresponding fire load according to the size of the pot 200, and then determine the number n of layers of the fire outlet channel 30 that need to be closed, which can meet the needs of balancing energy saving and cooking efficiency.

[0102] Fig.11 Another flow chart of the cooker load matching control method provided by the embodiment of the present application is shown. Fig.11 As shown, in step S200, the following steps are included:

[0103] S201, determining whether the time that the cooker 100 is in the current gear position is greater than T1; if so, executing S202. If not, it indicates that the user has made a manual adjustment.

[0104] T1 can be any value between 5s and 8s, such as 5s, 6s, 7s, and 8s.

[0105] S202 , start the sensor 106 to obtain parameters L, L1 and L2.

[0106] Among them, the numerical value of L is directly related to the size of the pot 200 and the bottom shape of the pot 200. Therefore, L is acquired by the sensor 106 in real time detecting the pot 200 and transmitted to the control module. L1 and L2 are related to the height dimension of the burner 103 and the height dimension of the pot rack 104, and the height dimension of the burner 103 and the height dimension of the pot rack 104 are fixed values. Therefore, L1 and L2 can be input into the control module in the form of manually measured preset parameters, so that the control module can be called when making decisions.

[0107] S203 . Determine the number n of layers of the fire outlet channels 30 that need to be closed according to the relationship among L, L1 and L2 .

[0108] Among them, when When n=0, all the fire outlet channels 30 are in an open state, and the burner 103 is in a maximum fire gear. The burner 103 in the maximum fire gear is suitable for cooking needs of a larger pot 200.

[0109] when When n=M-1, M is the total number of layers of the fire outlet channel 30 of the fire cover, that is, only one layer of the fire outlet channel 30 is kept in the open state, and the burner 103 is at the minimum fire power gear. The burner 103 at the minimum fire power gear is suitable for cooking needs of smaller pots 200.

[0110] when When n=1, one layer of the fire outlet channels 30 is closed, and the other fire outlet channels 30 are in an open state.

[0111] when When n=2, the second-floor fire outlet passage 30 is closed, and the other fire outlet passages 30 are in an open state.

[0112] when When n=3, the three-layer fire outlet passage 30 is closed, and the other fire outlet passages 30 are in an open state.

[0113] when When n=4, the fire outlet channels 30 on four floors are closed, and the other fire outlet channels 30 are open.

[0114] S204 , controlling the lifting stroke Sx of the air blocking ring 51 according to n, where Sx is the distance between the air blocking ring 51 and the bottom of the accommodation space in the current state.

[0115] Among them, the lifting stroke Sx of the air blocking ring 51 = S1-n*S2, S1 is the distance between the air blocking ring 51 and the bottom of the accommodation space when it is in the maximum stroke state, and when the air blocking ring 51 is in the maximum stroke state, all the fire outlet channels 30 are in the open state; S2 is the distance between the fire outlet channels 30 on each layer. Both S1 and S2 can be input into the control module in the form of manually measured preset parameters, so that the control module can be called when making decisions.

[0116] The stove load matching control method provided in the present application can accurately match the load requirements of various cookware 200 according to the different cookware 200 used by the user, thereby achieving energy conservation and emission reduction, improving the user's cooking experience, reducing cooking problems caused by human misjudgment, and providing more personalized and intelligent cooking services.

[0117] Next, taking a specific example as an example, the cooker load matching control method provided in this application is further explained.

[0118] In this example, the stove 100 has 6 layers of fire outlet channels 30. Before the stove 100 leaves the factory, the stove 100 needs to be set up to match different fire loads according to the diameters of different pots 200. For example, the fire loads of different fire outlet channels 30 layers can be set based on pots 200 with diameters of 38 cm, 35 cm, 32 cm, 29 cm, and 26 cm. For example, when the diameter of the pot 200 is greater than 38 cm, the number of fire layers of the fire outlet channel 30 is 6; when the diameter of the pot 200 is greater than 35 cm and less than or equal to 38 cm, the number of fire layers of the fire outlet channel 30 is 5; when the diameter of the pot 200 is greater than 32 cm and less than or equal to 35 cm, the number of fire layers of the fire outlet channel 30 is 4; when the diameter of the pot 200 is greater than 29 cm and less than or equal to 32 cm, the number of fire layers of the fire outlet channel 30 is 3; when the diameter of the pot 200 is greater than 26 cm and less than or equal to 29 cm, the number of fire layers of the fire outlet channel 30 is 2; when the diameter of the pot 200 is less than or equal to 26 cm, the number of fire layers of the fire outlet channel 30 is 1.

[0119] In the load control method of the stove 100 based on the stove 100, the number n of layers of the fire outlet passage 30 to be closed is determined according to the relationship among L, L1 and L2, specifically:

[0120] when When n=0;

[0121] when When n=1;

[0122] when When n=2;

[0123] when When n=3;

[0124] when When n=4;

[0125] when , n=5.

[0126] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
