[0002] Gas stoves are essential kitchen appliances in the cooking process, and the burner is the crucial device for achieving cooking goals. Thermal efficiency and CO concentration in dry flue gas are two important indicators for household gas stoves. Taking atmospheric built-in stoves as an example, the national standard GB16410-2020 "Household Gas Stoves" stipulates that the thermal efficiency should be ≥55% and the CO concentration in dry flue gas should be ≤0.05%; GB30720-2014 "Energy Efficiency Limits and Energy Efficiency Grades for Household Gas Stoves" stipulates that the thermal efficiency of Grade 1 energy efficiency should be ≥63%; and the group standard T / CNHA1023-2020 "Evaluation Requirements for 'Leader' Standards for Household Gas Stoves" stipulates that the advanced level requires a thermal efficiency of ≥70% and a CO concentration in dry flue gas of ≤0.03%.

[0003] Therefore, it is very important to ensure that the gas burns completely, reduce the emission of harmful fumes, and improve the thermal efficiency of the stove. Utility Model Content

[0014] The flame gas distributor is a flame gas distributor.

[0015] In the above technical solution, the fire hole channel includes a vertical channel section as the air intake section and an oblique channel section as the air outlet section.

[0016] The flame distribution plate is located in the inclined channel section of the flame hole channel.

[0017] In the above technical solution, the burner body includes a burner base, a burner cover and a flame cap. The burner cover is arranged around the outer ring of the burner base and forms an annular gas mixing chamber with the burner base.

[0025] 1. When the flame distribution plate in this application is installed in the burner, it can divide the flame from the burner's fire hole channel into multiple streams. When the flame distribution plate is installed in the burner's fire hole channel, its installation position can be set in the radial direction of the burner corresponding to the burner's foot plate. This can avoid the flame from directly interfering with the foot plate, greatly reduce the temperature of the flue gas and the foot plate, reduce heat loss, improve thermal efficiency and the durability of the pot support. At the same time, since the flame distribution plate is also provided with small ignition holes, it can also interrupt the flame without affecting the ignition effect. Attached Figure Description

[0085] Existing stove burners often suffer from the following technical problems:

[0086] 1. In existing technologies, the distribution of the gas-air mixture within the gas mixing chamber is not uniform enough, and the original tangential air intake direction cannot adequately adapt to combustion requirements. This results in an irregular flame pattern during gas combustion, low combustion efficiency, and high flue gas content, failing to meet increasingly stringent environmental protection and energy-saving requirements.

[0087] 2. The gas mixing chamber of existing burners is uneven, preventing the gas from being fully and evenly discharged for combustion. This not only affects the combustion efficiency, resulting in lower thermal efficiency, but also increases the content of flue gas produced during combustion, causing adverse environmental impacts. Furthermore, it fails to adequately meet users' demands for highly efficient and energy-saving gas stoves.

[0088] 3. In existing technologies, the burner's flame port channel lacks a corresponding gas distribution device, causing the flame to easily interfere with the pot support plates during combustion. This not only increases the temperature of the pot support plates, affecting the durability of the pot support, but also increases heat loss and reduces the burner's thermal efficiency. Furthermore, the uneven flame distribution also leads to an increase in the content of flue gas produced during combustion, failing to adequately meet environmental protection requirements.

[0089] 4. Existing burners exhibit significant downward heat conduction and diffusion during combustion, along with a substantial amount of excess secondary air. This results in low thermal efficiency, hindering the full utilization of heat generated by the combustion gas, increasing energy consumption, and leading to relatively high flue gas content, which contradicts the trend of energy conservation and environmental protection. Furthermore, the versatility of these burners is limited, hindering the flexible application of burners with different structures.

[0090] In view of the above-mentioned technical problems, this application provides several different embodiments that can solve at least one of the above-mentioned technical problems.

[0091] Example 1

[0092] like Figures 1a-1f As shown, the first aspect of this embodiment provides an annular gas distributor 30, which is circumferentially disposed at the communication position between the annular gas mixing chamber 21 and the annular flame hole channel 22 in the burner body. The annular gas distributor 30 includes:

[0093] The ring body 33 has multiple upwardly protruding gas distribution teeth 32 distributed circumferentially on its upper surface. The gap between each pair of adjacent gas distribution teeth 32 forms a gas distribution groove 31 that connects the gas mixing chamber and the flame hole channel.

[0094] In this embodiment of the application, by setting a gas distribution component with multiple gas distribution slots 31, the gas-air mixture that enters the gas mixing chamber tangentially can be discharged in the vertical direction, thereby improving the lifting and ejection capability of the burner, making the annular thin flame pattern of gas combustion more standardized, and reducing the flue gas content.

[0095] It is worth noting that the aforementioned annular fire hole channel 22 can be composed of a single component or multiple components working together. This embodiment does not limit the specific configuration of the annular fire hole channel 22.

[0096] Furthermore, in some possible implementations,

[0097] The air-splitting teeth 32 are straight teeth, and the center surface of each straight tooth passes through the center line of the annular body 33.

[0098] or

[0099] The air-splitting teeth 32 are helical teeth, and the center surface of each helical tooth is parallel to the center line of the ring body.

[0100] Furthermore, in some possible embodiments, the radial outer height of the air distribution tooth 32 is higher than its radial inner height, and the upper end surface of the air distribution tooth 32 is a stepped surface or a sloping surface.

[0101] In this embodiment, by setting the radial outer height of the gas distribution tooth 32 to be higher than its radial inner height, and setting the upper end face of the gas distribution tooth 32 as a stepped surface or a slope surface, the space on the gas outlet side of the gas distribution groove 31 can be made larger, thereby further improving the ejection capability of the burner and further reducing the flue gas content of the burner.

[0102] Furthermore, in some possible embodiments, the upper end face of the air distribution tooth 32 includes a first transverse surface 321 extending horizontally, a first vertical surface 323 extending downward from the inner end side of the first transverse surface 321 along the height direction of the air distribution tooth 32, and a second transverse surface 322 extending horizontally towards the inner side of the ring body 33 from the lower end side of the first vertical surface 323, wherein the first transverse surface 321 constitutes the tooth tip surface of the air distribution tooth 32.

[0103] In this embodiment, the gas distribution tooth 32 has a notch on the side that mates with the burner base. This notch can mate with the burner base to form a cavity, which makes the space on the gas outlet side of the gas distribution groove 31 larger, thereby further improving the ejection capability of the burner and further reducing the flue gas content of the burner.

[0104] Furthermore, in some possible implementations, the ratio of the axial height of the air distribution tooth 32 to the height of the first vertical surface 323 is between 2.5 and 3;

[0105] The ratio of the radial width of the air distribution tooth 32 to the radial length of the first transverse surface 321 is between 2 and 2.5, and the ratio of the radial width of the air distribution tooth 32 to the radial length of the second transverse surface 322 is between 2 and 2.5.

[0106] The ratio of the circumference of the ring body 33 to the circumferential width of the air distribution tooth 23 is between 130 and 150, and the ratio of the circumference of the ring body 33 to the circumferential width of the air distribution groove 31 is between 130 and 150.

[0107] Furthermore, in some possible implementations, the bottom surface of the gas distribution groove 31 is inclined upwards towards the radially inward side;

[0108] and / or

[0109] The cross-section of the gas distribution groove 31 in the circumferential direction is a surface of equal width;

[0110] and / or

[0111] The flow area of ​​the air distribution groove 31 gradually increases along the inflow and outflow direction of the airflow.

[0112] The second aspect of this embodiment provides a burner base, wherein the burner base 10 is integrally formed with the annular gas distribution component 30 provided in the first aspect of this embodiment.

[0113] The third aspect of this embodiment provides a burner body, which is provided with the burner base 10 provided in the second aspect of this embodiment.

[0114] Furthermore, in some possible embodiments, the burner body 20 is provided with an annular gas mixing chamber 21 and an annular flame hole channel 22 communicating with the gas mixing chamber 21;

[0115] An annular gas distributor 30 is provided at the connection position between the gas mixing chamber 21 and the flame hole channel 22;

[0116] The annular gas distributor 30 is the annular gas distributor provided in the first aspect of this embodiment.

[0117] Furthermore, in some possible implementations, the annular gas distributor 30 is integrally formed with the burner body.

[0118] Furthermore, in some possible embodiments, the burner body 20 includes a burner base 20a, a burner cover 20b, and a flame cap 20c, wherein:

[0119] The burner cover 20b is arranged around the outer ring of the burner base 20a and forms an annular gas mixing chamber 21 with the burner base 20a;

[0120] The burner cap 20c is arranged on the inner ring side of the burner base 20a and forms a circumferentially connected annular gap with the end of the burner cap 20b. The annular gap forms a fire hole channel 22 that communicates with the gas mixing chamber 21.

[0121] The gas mixing chamber 21 is connected to the flame hole channel 22 on the side near the flame hole channel 22, and an annular gas distributor 30 is provided at the connection position;

[0122] The annular gas distributor 30 is the annular gas distributor provided in the first aspect of this embodiment.

[0123] Furthermore, in some possible implementations, the annular gas distributor 30 is integrally formed from the burner base 20a.

[0124] Furthermore, in some possible embodiments, the end of the burner cover 20b that is upward away from the inner ring of the burner seat forms an inwardly bent edge 20b1, and the inwardly bent edge 20b1 of the burner cover 20b and the burner cap 20c form a flame hole channel 22.

[0125] There is a gap between the free end of the inwardly bent edge 20b1 of the burner cover 20b and the upper end face of the annular gas distributor 30. The gap forms the communication port 40 between the gas mixing chamber 21 and the flame hole channel 22.

[0126] When a gas distributor with multiple gas distribution teeth 32 is installed in the gas mixing chamber, the upper tooth surface of the gas distribution teeth 32 can correspond to the bottom end of the flame hole channel, and the two are spaced apart. This can reduce the resistance encountered by the annular gas distributor during gas distribution.

[0129] The inner peripheral wall of the ring rib 20a1 is fitted together with the outer peripheral wall of the fire cover 20c.

[0130] Furthermore, in some possible embodiments, the inwardly bent edge 20b1 of the burner cover 20b includes a burner cover oblique portion 20b11 and a burner cover vertical portion 20b12.

[0131] The flame cap 20c includes an oblique portion 20c11 and a vertical portion 20c12;

[0132] The inclined portion 20b11 of the burner cover and the inclined portion 20c11 of the flame cap are fitted together to form the inclined portion of the flame hole channel 22;

[0133] The vertical portion 20b12 of the burner cover and the vertical portion 20c12 of the flame cap are fitted together to form the vertical portion of the flame hole channel 22;

[0134] The ring rib 20a1 protrudes upward into the vertical part of the flame hole channel 22, and the inner peripheral wall of the ring rib 20a1 fits together with the outer peripheral wall of the vertical part of the flame cap 20c.

[0135] The inlet flow area of ​​the vertical part of the fire hole channel 22 is smaller than the outlet flow area of ​​the inclined part of the fire hole channel 22.

[0136] Furthermore, in some possible embodiments, the burner body also includes a plurality of foot pieces 10 arranged circumferentially along the burner base 20a;

[0137] The burner body also includes multiple flame distribution plates 50 arranged circumferentially within the flame hole channel 22. The multiple flame distribution plates 50 are located inside the multiple pot foot plates 10 and their positions correspond one-to-one with the multiple pot foot plates 10.

[0138] Each flame distribution plate 50 is provided with an ignition channel 51, which extends from the air inlet side of the flame hole channel 22 to the air outlet side of the flame hole channel 22.

[0139] The flame distribution plate 50 has a first mating surface and a second mating surface, wherein the first mating surface mates with the flame cap 20c and the second mating surface mates with the burner cap 20b;

[0140] The flame distribution plate 50 is configured to impede the circumferential flow and radial outflow of the gas mixture at the location of its flame hole channel 22, but allows the gas mixture to flow out of the ignition channel 501 for combustion.

[0141] Furthermore, in some possible embodiments, a channel structure is formed on the first mating surface to the side of the second mating surface, the channel structure forming an ignition channel 501, and a protrusion structure 52 is formed on the second mating surface at the position corresponding to the channel structure, the protrusion structure 52 on the second mating surface side mating together with the flame cap 20c.

[0142] Furthermore, in some possible embodiments, the burner base 20a is provided with a foot plate slot 20a1, and the foot plate 10 is inserted into the foot plate slot 20a1 of the burner base 20a.

[0143] The fourth aspect of this application provides a stove burner, which includes the burner body provided in the third aspect of this application.

[0144] The fourth aspect of this application also provides a stove burner, which is provided with a high-fire burner body and a low-fire burner body, wherein the high-fire burner body adopts the burner body provided in the third aspect of this application.

[0145] In summary, this embodiment utilizes an annular gas distributor located at the junction of the gas mixing chamber and the flame port channel in the burner body. Multiple gas-distributing teeth on the annular component form gas-distributing grooves, effectively altering the flow direction of the gas-air mixture from tangential intake to vertical exhaust. This improvement significantly enhances the burner's ejection capability, resulting in a more standardized flame pattern and an ideal annular thin flame. This, in turn, reduces the amount of flue gas produced during combustion, improving combustion efficiency and environmental performance.

[0146] Furthermore, the gas distribution teeth are designed with a higher radial outer side than a higher radial inner side, and the upper surface adopts a stepped or sloping structure. This unique structural design further increases the space on the outlet side of the gas distribution slot, thereby further enhancing the ejector capability of the burner, allowing the gas mixture to be discharged more smoothly and burned more completely, further reducing the flue gas content and optimizing the combustion effect.

[0147] Furthermore, the annular gas distributor is integrally molded with the burner base, which not only improves the overall structural stability of the burner, but also reduces assembly errors and connection gaps between components, ensuring the uniformity and stability of the gas mixture during the flow process. This helps to further improve combustion efficiency and reduce flue gas content, while simplifying the burner manufacturing process and reducing production costs.

[0148] Furthermore, the burner port channel is formed by the inward bending edge of the burner cap and the burner cap, with the inlet flow area of ​​its vertical portion being smaller than the outlet flow area of ​​its inclined portion. This structural design helps control the flow velocity and pressure distribution of the gas-fuel mixture within the burner port channel, allowing the gas-fuel mixture to be discharged and burned more evenly from the burner port channel. This further improves the stability and uniformity of combustion, reduces localized high temperatures and incomplete combustion, thereby reducing the amount of pollutants generated in the flue gas and improving the environmental performance of the burner.

[0149] Furthermore, flame distribution plates are spaced circumferentially within the burner channel, dividing the flame into multiple segments and preventing direct interference between the flame and the pot support. This improvement not only reduces the temperature of the pot support, minimizing heat loss and improving thermal efficiency, but also enhances the burner's durability and extends the pot support's lifespan. Simultaneously, the ignition channels on the flame distribution plates allow the gas mixture to flow out for combustion, ensuring continuous and stable combustion and further optimizing the combustion effect.

[0150] In summary, through the aforementioned series of structural optimizations and improvements, the burner's ejection capability, the uniformity of gas-fuel mixture distribution, and the stability and uniformity of combustion have all been significantly enhanced. This allows for more complete combustion of the gas, releasing more heat and thus achieving a substantial increase in burner thermal efficiency. This meets users' demands for high-efficiency and energy-saving gas stoves while also reducing energy consumption, resulting in significant economic and social benefits. The improved burner has achieved remarkable results in reducing flue gas content, effectively reducing the emission of harmful gases and pollutants such as carbon monoxide (CO) during combustion. This elevates the burner's environmental performance to a higher standard, complying with relevant national environmental regulations and playing a vital role in improving environmental quality. The integrated design of the burner base and gas distribution components, along with the tight fit between all components, improves the overall structural stability of the burner, reduces the probability of component loosening or detachment, enhances the burner's reliability and lifespan, and lowers user operating costs and maintenance workload.

[0151] Example 2

[0152] like Figures 2a-2f As shown, in the first aspect of this embodiment, the burner body 20 is provided with:

[0153] The annular gas mixing chamber 21 and the annular flame hole channel 22 communicating with the gas mixing chamber 21, the gas mixing chamber 21 having a mixing chamber inlet 211 capable of gas entering along the tangential direction of the gas mixing chamber 21;

[0154] An annular gas distributor 30 is disposed within the gas mixing chamber 21.

[0155] The annular gas distributor 30 has multiple gas distribution grooves 31 formed in its circumferential direction. Each of the multiple gas distribution grooves 31 can connect the gas mixing chamber 21 and the flame hole channel 22. The multiple gas distribution grooves 31 are used to divide the gas-air mixture in the gas mixing chamber 21 into multiple streams and guide them upward to the flame hole channel 22.

[0156] In this embodiment, an annular gas distributor with multiple gas distribution grooves 31 is provided in the gas mixing chamber. This allows the gas-air mixture that enters the gas mixing chamber tangentially to be discharged vertically, thereby improving the lifting and ejection capability of the burner, making the annular thin flame of gas combustion more standardized, and reducing the flue gas content.

[0157] Furthermore, in some possible embodiments, the gas mixing chamber 21 includes an outer ring and an inner ring.

[0158] Furthermore, in some possible embodiments, the burner body 20 includes a burner base 20a, a burner cover 20b, and a flame cap 20c, wherein:

[0159] The burner cover 20b is arranged around the outer ring of the burner base 20a and forms an annular gas mixing chamber 21 with the burner base 20a;

[0160] The burner cap 20c is arranged on the inner ring side of the burner base 20a and forms a circumferentially connected annular gap with the end of the burner cap 20b. The annular gap forms a fire hole channel 22 that communicates with the gas mixing chamber 21.

[0161] The gas mixing chamber 21 is connected to the flame hole channel 22 on the side near the flame hole channel 22, and the annular gas distributor 30 is located at the connection position between the gas mixing chamber 21 and the flame hole channel 22.

[0162] In this embodiment, by setting the annular gas distributor 30 at the connection position between the gas mixing chamber 21 and the flame hole channel 22, the multiple airflows separated by the annular gas distributor 30 can be directly discharged upward into the flame hole channel 22, reducing the flow resistance of the gas-air mixture.

[0163] Furthermore, in some possible implementations, the annular gas distributor 30 is integrally formed from the burner base 20a.

[0164] Furthermore, in some possible embodiments, the burner base 20a is provided with annular ribs 20a1 on the radial inner side of the annular gas distribution member 30, and the annular ribs 20a1 protrude upward into the fire hole channel 22.

[0165] The outer peripheral wall of the ring rib 20a1 is fitted together with the inner peripheral wall of the annular air distribution component 30;

[0166] The inner peripheral wall of the ring rib 20a1 is fitted together with the outer peripheral wall of the fire cover 20c.

[0168] There is a gap between the free end of the inwardly bent edge 20b1 of the burner cover 20b and the upper end face of the annular gas distributor 30. The gap forms the communication port 40 between the gas mixing chamber 21 and the flame hole channel 22.

[0169] The inwardly bent edge 20b1 of the burner cover 20b includes the inclined portion 20b11 of the burner cover and the vertical portion 20b12 of the burner cover;

[0170] The flame cap 20c includes an oblique portion 20c11 and a vertical portion 20c12;

[0171] The inclined portion 20b11 of the burner cover and the inclined portion 20c11 of the flame cap are fitted together to form the inclined portion of the flame hole channel 22;

[0172] The vertical portion 20b12 of the burner cover and the vertical portion 20c12 of the flame cap are fitted together to form the vertical portion of the flame hole channel 22;

[0173] The ring rib 20a1 protrudes upward into the vertical part of the flame hole channel 22, and the inner peripheral wall of the ring rib 20a1 fits together with the outer peripheral wall of the vertical part of the flame cap 20c.

[0174] The inlet flow area of ​​the vertical part of the fire hole channel 22 is smaller than the outlet flow area of ​​the inclined part of the fire hole channel 22.

[0175] Furthermore, in some possible embodiments, the annular gas distributor 30 includes:

[0176] The ring body 33 has multiple upwardly protruding gas distribution teeth 32 distributed circumferentially on its upper surface. The gap between each pair of adjacent gas distribution teeth 32 forms a gas distribution groove 31 that connects the gas mixing chamber 21 and the flame hole channel 22.

[0177] The air-splitting teeth 32 are straight teeth, and the center surface of each straight tooth passes through the center line of the annular body 33.

[0178] or

[0179] The air-splitting teeth 32 are helical teeth, and the center surface of each helical tooth is parallel to the center line of the ring body 33.

[0180] Furthermore, in some possible embodiments, the radial outer height of the air distribution tooth 32 is higher than its radial inner height, and the upper end surface of the air distribution tooth 32 is a stepped surface or a sloping surface.

[0181] Furthermore, in some possible embodiments, the upper end face of the air distribution tooth 32 includes a first transverse surface 321 extending in the horizontal direction, a first vertical surface 323 extending downward in the height direction of the air distribution tooth 32 from the inner end side of the first transverse surface 321, and a second transverse surface 322 extending in the horizontal direction towards the inner side of the ring body 33 from the lower end side of the first vertical surface 323.

[0182] The first transverse surface 321 forms the tip surface of the air-splitting tooth 32.

[0183] Furthermore, in some possible implementations, the ratio of the axial height of the air distribution tooth 32 to the height of the first vertical surface 323 is between 2.5 and 3;

[0184] The ratio of the radial width of the air distribution tooth 32 to the radial length of the first transverse surface 321 is between 2 and 2.5, and the ratio of the radial width of the air distribution tooth 32 to the radial length of the second transverse surface 322 is between 2 and 2.5.

[0185] The ratio of the circumference of the ring body 33 to the circumferential width of the air distribution tooth 23 is between 130 and 150, and the ratio of the circumference of the ring body 33 to the circumferential width of the air distribution groove 31 is between 130 and 150.

[0186] Furthermore, in some possible implementations, the bottom surface of the gas distribution groove 31 is inclined upwards towards the radially inward side;

[0187] and / or

[0188] The cross-section of the gas distribution groove 31 in the circumferential direction is a surface of equal width;

[0189] and / or

[0190] The flow area of ​​the air distribution groove 31 gradually increases along the inflow and outflow direction of the airflow.

[0191] Furthermore, in some possible embodiments, the annular gas distributor 30 includes:

[0192] The ring body 33 has multiple upwardly protruding gas distribution teeth 32 distributed circumferentially on its upper surface. The gap between each pair of adjacent gas distribution teeth 32 forms a gas distribution groove 31 that connects the gas mixing chamber and the flame hole channel.

[0193] The second aspect of this embodiment provides a stove burner, which includes the burner body provided in the first aspect of this embodiment.

[0194] The second aspect of this embodiment also provides a stove burner, which includes a high-fire burner body and a low-fire burner body, wherein the high-fire burner adopts the burner body provided in the first aspect of this embodiment.

[0195] In summary, by setting an annular gas distributor with multiple gas distribution slots in the gas mixing chamber, the gas-air mixture that enters the gas mixing chamber tangentially can be discharged vertically, thereby improving the ejector capability of the burner, making the gas combustion flame pattern more standardized, and reducing the flue gas content.

[0196] Furthermore, the gas mixing chamber includes an outer ring and an inner ring. The gas outlet of the mixing chamber is connected to the gas mixing chamber near the outer ring, and the flame port channel is connected to the gas mixing chamber near the inner ring. An annular gas distributor is located in the inner ring of the gas mixing chamber. This allows the gas-air mixture ejected from the injector to collect at the outer ring of the gas mixing chamber. After being distributed by the annular gas distributor in the inner ring, the mixture is discharged axially through the flame port channel above, changing the flow direction of the gas-air mixture within the gas mixing chamber and further improving the injector's injection capability.

[0197] Furthermore, by configuring the burner body to include a burner base, a burner cover, and a flame cap, with the burner cover and burner base forming a gas mixing chamber, and the flame cap and the end of the burner cover forming a flame port channel; an annular gas distributor is positioned at the connection point between the gas mixing chamber and the flame port channel. This allows the multiple gas streams separated by the annular gas distributor to be directly discharged upwards into the flame port channel, reducing the flow resistance of the gas-air mixture and improving combustion efficiency.

[0198] Furthermore, a flame port channel is formed between the inwardly bent edge of the burner cap and the flame cap. The inwardly bent edge of the burner cap includes an oblique portion and a vertical portion, and the flame cap also includes an oblique portion and a vertical portion. These two components work together to form the oblique and vertical portions of the flame port channel, respectively. A ring rib protrudes upward into the vertical portion of the flame port channel, and the inner circumferential wall of the ring rib fits into the outer circumferential wall of the vertical portion of the flame cap. The inlet flow area of ​​the vertical portion of the flame port channel is smaller than the outlet flow area of ​​the oblique portion. This optimized structure of the flame port channel allows for smoother flow of the gas-fuel mixture within the channel, further improving combustion stability and uniformity, reducing localized high temperatures and incomplete combustion, lowering the amount of pollutants generated in the flue gas, and enhancing the environmental performance of the burner.

[0199] Furthermore, the gas distribution teeth are straight or helical, with the radial outer height of the gas distribution teeth being higher than their radial inner height, and the upper end face of the gas distribution teeth being a stepped or sloping surface; the upper end face of the gas distribution teeth includes a first transverse surface, a first vertical surface, and a second transverse surface arranged sequentially. This further increases the space on the outlet side of the gas distribution groove, reduces the resistance encountered by the annular gas distribution component during gas distribution, allows the gas mixture to be discharged more smoothly and combusted more completely, further improves the ejector capability of the burner, and reduces the flue gas content.

[0200] Furthermore, the ratios of the axial height of the gas distribution tooth to the height of the first vertical plane, the ratio of the radial width of the gas distribution tooth to the radial length of the first transverse plane, the ratio of the radial width of the gas distribution tooth to the radial length of the second transverse plane, the ratio of the circumference of the ring body to the circumferential width of the gas distribution tooth, and the ratio of the circumference of the ring body to the circumferential width of the gas distribution groove were optimized. The bottom surface of the gas distribution groove is inclined radially inward and upward, the cross-section of the gas distribution groove in the circumferential direction is a surface of equal width, and the flow area of ​​the gas distribution groove gradually increases along the inflow and outflow direction of the airflow. By optimizing the size and shape, the gas distribution effect and the performance of the burner are further improved, the distribution of the gas mixture is more uniform, the combustion is more complete, the flue gas content is further reduced, and the combustion efficiency and thermal efficiency are improved.

[0201] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves, while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0202] Example 3

[0203] like Figures 3a-3e As shown, the first aspect of this embodiment provides a gas distributor 70, which is disposed in the annular gas mixing chamber 21 of the burner body 20. The gas distributor 70 is a sheet structure, and the sheet structure has a first edge and a second edge opposite to each other in the circumferential direction. The area between the first edge and the second edge constitutes a gap area.

[0204] The gas distributor 70 is configured such that when the gas distributor 70 is arranged circumferentially in the gas mixing chamber 21, the gas distributor divides the gas mixing chamber 211 into an upper gas mixing chamber 21a and a lower gas mixing chamber 21b, and the position of the notch area of ​​the gas distributor 70 in the gas mixing chamber 21 corresponds to the position of the air inlet 211 of the gas mixing chamber 21.

[0205] In this embodiment of the application, by providing a gas distributor 70 in the gas mixing chamber, the gas-air mixture can be distributed more evenly in the gas mixing chamber, so that the content of flue gas produced during combustion can be reduced when the gas is discharged for combustion.

[0206] Furthermore, in some possible implementations, the gas distributor is a C-shaped gas distributor.

[0207] It should be noted that the gas distribution component mentioned in the embodiments of this application is not required to be a C-shape in a completely mathematical sense. It only needs to be roughly C-shaped. At the same time, the arc length of the notch area of ​​the gas distribution component 70 mentioned in the embodiments of this application is smaller than the arc length of the solid part, so as to achieve a better layered gas distribution effect.

[0208] Furthermore, a second aspect of the embodiments of this application also provides a burner body,

[0209] The burner body 20 is provided with an annular gas mixing chamber 21 and an annular flame hole channel 22 connected to the gas mixing chamber 21. The lower part of the gas mixing chamber 21 is provided with an air inlet 211 for supplying gas mixture into the gas mixing chamber 21, and the side is provided with an air outlet for supplying the gas mixture in the gas mixing chamber to the flame hole channel 22.

[0210] The gas mixing chamber 21 is provided with a gas distributor arranged circumferentially along the gas mixing chamber 21. The gas distributor is used to divide the gas mixing chamber 211 into an upper gas mixing chamber 21a and a lower gas mixing chamber 21b. The upper gas mixing chamber 21a and the lower gas mixing chamber 21b are connected to the gas outlet on the radial inner side. The gas distributor 70 is configured such that the position of its notch area in the gas mixing chamber 21 corresponds to the position of the gas inlet 211 of the gas mixing chamber 21.

[0211] The gas distributor is the gas distributor provided in the first aspect of this embodiment.

[0212] In this embodiment of the application, by providing a gas distributor 70 in the gas mixing chamber of the burner body, the gas-air mixture can be more evenly distributed in the gas mixing chamber, so that the content of flue gas generated during combustion can be reduced when the gas is discharged for combustion.

[0213] Furthermore, in some possible embodiments, the intake airflow supplied by the gas mixing chamber inlet 211 is designed to flow from the second edge 702 side to the first edge 701 side, and the position of the notch of the gas distributor within the gas mixing chamber 21 corresponds to the position of the gas mixing chamber inlet 211 in one of the following cases:

[0214] In the first scenario, viewed from the top view, the air inlet 211 of the gas mixing chamber 21 is located within the circumferential area defined by the first edge 701 and the second edge 702 and does not overlap with the first edge 701 and the second edge 702.

[0215] In the second scenario, viewed from the top view, the air inlet 211 of the gas mixing chamber is located within the circumferential region defined by the first edge 701 and the second edge 702, wherein the end of the air inlet 211 of the gas mixing chamber 21 near the first edge 701 is located within the circumferential region defined by the first edge 701 and the second edge 702.

[0216] In other words, in this embodiment of the application, the gas mixing chamber inlet 21 corresponds at least partially to the notch of the gas distributor 70. This way, when the gas-air mixture enters the gas mixing chamber tangentially, it will not be blocked by the annular gas distributor 70 located above, thereby avoiding reducing the flow resistance of the gas-air mixture when entering the gas mixing chamber.

[0217] Furthermore, in some possible implementations, the end of the gas mixing chamber 21 inlet 211 near the first edge 211 is spaced apart from the first edge 701 by a distance a, and the end of the gas mixing chamber 21 inlet 211 near the second edge 702 is spaced apart from the second edge 702 by a distance b.

[0218] Where a>0, b>0.

[0219] Furthermore, in some possible implementations, when the position of the gap region within the gas mixing chamber 21 is in the first case, 0mm < a < 20mm, 0mm < b < 20mm;

[0220] When the gap area is located in the second case within the gas mixing chamber 21, 0mm < a < 20mm, 0mm < b < 15mm.

[0221] As can be seen from the above description, in this embodiment of the application, the end of the mixing chamber inlet 211 near the first edge of the air distributor 70 cannot be blocked by the air distributor 70, while the end of the mixing chamber inlet 211 near the second edge of the air distributor 70 can be blocked by the air distributor 70.

[0222] Furthermore, in some possible embodiments, the burner body 20 also includes:

[0223] The ejector channel is connected to the air inlet 211 of the gas mixing chamber;

[0224] The ejector channel is designed as an inclined channel that extends upward from the second edge 702 side of the air inlet to the first edge 701 side of the air inlet, so that the airflow in the ejector channel can flow tangentially into the gas mixing chamber 21 through the air inlet 211 of the gas mixing chamber 21.

[0225] The reason why the gas-air mixture in this embodiment can flow into the gas mixing chamber along the tangential direction is due to the ejector channel structure of the ejector tube. In other words, by improving the ejector channel structure of the ejector tube in this embodiment, the gas-air mixture can flow into the gas mixing chamber tangentially, thereby improving the mixing effect between gas and air.

[0226] Furthermore, in some possible embodiments, the burner body 20 includes a burner base 20a, a burner cover 20b, and a flame cap 20c, wherein:

[0227] The burner cover 20b is arranged around the outer ring of the burner base 20a and forms an annular gas mixing chamber 21 with the burner base 20a;

[0228] The burner cap 20c is arranged on the inner ring side of the burner base 20a and forms a circumferentially connected annular gap with the end of the burner cap 20b. The annular gap forms a fire hole channel 22 that communicates with the gas mixing chamber 21.

[0229] The ejector channel and the burner base 20a are integrally formed.

[0230] Furthermore, in some possible embodiments, the burner body also includes an annular gas distributor 30 circumferentially disposed at the location where the gas mixing chamber communicates with the flame port channel; wherein

[0231] The annular gas distributor 30 is positioned lower than the gas distributor 70, and is used to divide the gas-air mixture in the lower gas mixing chamber 21a into multiple streams and guide them into the flame hole channel 22.

[0232] or

[0233] The annular gas distributor 30 is positioned higher than the gas distributor 70, and is used to divide the gas-air mixture in the upper gas mixing chamber 21b into multiple streams and guide them into the flame hole channel 22.

[0234] or

[0235] The annular gas distributor 30 is positioned corresponding to the gas distributor 70, and is used to divide the gas-air mixture in the upper gas mixing chamber into multiple streams and guide them into the flame hole channel 22, and to divide the gas-air mixture in the lower gas mixing chamber into multiple streams and guide them into the flame hole channel 22.

[0236] Preferably, the annular gas distributor 30 is positioned corresponding to the gas distributor 70, and is used to divide the gas-air mixture in the upper gas mixing chamber into multiple streams and guide them into the burner channel 22, and to divide the gas-air mixture in the lower gas mixing chamber into multiple streams and guide them into the burner channel 22. This configuration of the gas distributor 70 allows for the separation of the gas-air mixture in the gas mixing chamber into upper and lower layers, improving the mixing effect between gas and air. The annular gas distributor 30 further redirects the separated gas-air mixture before discharge, thereby improving the ejector's injection capability and ultimately enhancing the burner's combustion efficiency.

[0237] Furthermore, in some possible embodiments, the annular gas distributor 30 has a plurality of gas distribution grooves 31 formed in its circumferential direction. Each of the plurality of gas distribution grooves 31 can connect the gas mixing chamber 21 and the ignition channel 22. The plurality of gas distribution grooves 31 are used to divide the gas-air mixture in the gas mixing chamber 21 into multiple streams and guide them upward to the ignition channel 22.

[0238] Furthermore, in some possible embodiments, the gas mixing chamber 21 includes an inner ring and an outer ring, and the flame port channel 22 is located above the inner ring.

[0239] The annular gas distributor 30 is disposed on one side of the inner ring of the gas mixing chamber 21, and the gas distributor 70 is disposed between the annular gas distributor 30 and the outer ring.

[0240] Furthermore, in some possible embodiments, a gap c is formed between the inner ring side of the air distributor 70 and the outer ring side of the annular air distributor 30.

[0241] Furthermore, in some possible embodiments, the annular air distribution member 30 includes an annular toothed air distribution plate having a plurality of air distribution teeth 32 in the circumferential direction, and an air distribution groove 31 is formed between two adjacent air distribution teeth 32.

[0242] The top surface of the air distribution tooth 31 is higher than the upper plate surface of the air distribution component 70.

[0243] The third aspect of this embodiment provides a stove burner, which includes a small flame burner body that emits flame at the center of the burner and a large flame burner body that emits flame outside the small flame burner body.

[0244] The main body of the large-fire burner adopts the burner body provided in the second aspect of this embodiment.

[0245] In summary, this embodiment utilizes a plate-shaped gas distributor with a notched area within the annular gas mixing chamber of the burner body. This notched area divides the gas mixing chamber into an upper and lower gas mixing chamber, with the notched area corresponding to the air inlet position of the gas mixing chamber. This allows for more uniform gas distribution within the gas mixing chamber, reducing the amount of flue gas produced during combustion and improving combustion efficiency and environmental performance.

[0246] Furthermore, the gas distributor is C-shaped, with the arc length of the notch area being shorter than the arc length of the solid portion. This achieves better stratified gas distribution, further improving the uniformity of the gas-fuel mixture distribution within the gas mixing chamber and optimizing combustion performance.

[0247] Furthermore, the air inlet of the gas mixing chamber is designed to flow from the second edge of the gas distributor to the first edge, with specific correspondences between the notch area and the air inlet position. This ensures that when the gas-air mixture enters the gas mixing chamber tangentially, it is not blocked by the upper gas distributor, thus avoiding reduced flow resistance and guaranteeing smooth entry and uniform distribution of the gas mixture.

[0248] Furthermore, the ejector channel is connected to the air inlet of the gas mixing chamber and is designed as an inclined channel extending upwards from the second edge of the air inlet to the first edge of the air inlet. This allows the gas-air mixture to flow tangentially into the gas mixing chamber, improving the mixing effect between the gas and air and further optimizing combustion conditions.

[0249] Furthermore, the burner body includes a burner base, a burner cover, and a flame cap. The burner cover and burner base form a gas mixing chamber, and the ends of the flame cap and burner cover form a flame channel. The ejector channel is integrally formed with the burner base. Through the reasonable cooperation of various components, a complete burner body structure is formed, ensuring the smooth flow of the gas mixture and the stable operation of the combustion process.

[0250] Furthermore, an annular gas distributor is circumferentially installed at the connection point between the gas mixing chamber and the burner channel. The annular gas distributor can be positioned in various ways, further dividing the stratified gas-air mixture into multiple streams before guiding them into the burner channel. This further alters the flow direction of the gas mixture, improves the ejector tube's ejection capacity, optimizes combustion, ensures more complete combustion, further reduces flue gas content, and improves combustion and thermal efficiency.

[0251] Furthermore, the annular gas distributor has multiple gas distribution grooves formed in its circumferential direction; the gas mixing chamber includes an inner ring and an outer ring, with the flame port channel located above the inner ring. The annular gas distributor is positioned on one side of the inner ring of the gas mixing chamber, and between the annular gas distributor and the outer ring; a gap is formed between the inner ring side and the outer ring side of the annular gas distributor; the annular gas distributor includes annular toothed gas distribution plates, with the tooth tip surface higher than the upper plate surface of the gas distributor. This further optimizes the distribution and flow of the gas mixture, improves the burner performance, makes combustion more stable and uniform, further reduces the flue gas content, and improves combustion efficiency and thermal efficiency.

[0252] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0253] Example 4

[0254] like Figures 4a-4f As shown, the first aspect of this embodiment provides a flame distribution plate. The flame distribution plate 10 is used to be installed in the annular flame hole channel 22 of the burner body. The flame distribution plate includes a plate body and the plate body is provided with an ignition channel 101. The ignition channel 101 is used to allow part of the gas mixture to flow out of the ignition channel 101 for combustion when the flame distribution plate 10 is installed in the flame hole channel 22.

[0255] In this embodiment, the flame distribution plate 10 can divide the flame from the fire hole channel into multiple streams. When the flame distribution plate 10 is installed in the fire hole channel, its installation position can be set in the radial direction corresponding to the burner's foot plate. This can avoid the flame from directly interfering with the foot plate, greatly reduce the temperature of the flue gas and the foot plate, reduce heat loss, improve thermal efficiency and the durability of the pot support. At the same time, since the flame distribution plate 10 is also provided with a small hole-shaped ignition channel 101, the ignition effect can be maintained without interrupting the flame.

[0256] Furthermore, in some possible embodiments, the sheet body is an arched structure, with the arched structure forming an ignition channel 101 at its bend.

[0257] Furthermore, in some possible implementations, the crown of the arch is a curved arch.

[0258] Furthermore, in some possible implementations, the sheet body has a socket structure formed at one end of its ignition channel 101 extending in the direction of extension.

[0259] Furthermore, in some possible embodiments, the sheet body forms overlapping portions on both sides of its arch, the bottom surface of the overlapping portion is used to mate with the bottom surface of the annular fire hole channel 22, and the top surface of the arch mates with the top surface of the annular fire hole channel 22.

[0260] Furthermore, in some possible implementations, the burner body includes:

[0261] The burner base 20a, burner cover 20b and flame cap 20c are provided. The burner cover 20b is arranged around the outer ring of the burner base 20a and forms a circumferentially connected gas mixing chamber 21 with the burner base 20a. The flame cap 20c is arranged around the inner ring of the burner base 20a and forms a circumferentially connected annular flame hole channel 22 with the end of the burner cover 20b.

[0262] The bottom surface of the overlapping part contacts and fits together with the burner cap 20c, and the top surface of the arch contacts and fits together with the burner cap.

[0263] In this embodiment, by providing a flame distribution plate 10 between the burner cap and the burner cover, the gap between the flame hole channel 22 between the burner cap 20c and the burner cover 20b and the height of the flame distribution plate 40 can be kept the same, facilitating the control of the size of the flame hole channel 22. In other words, in this embodiment, only the height of the flame distribution plate 10 needs to be designed accordingly to ensure that the gap between the flame hole channel and the burner cover meets the corresponding design requirements. This simplifies the manufacturing process of the burner cap and the burner cover and allows for very precise control of the dimensional accuracy of the flame hole channel between the burner cap and the burner cover.

[0264] The second aspect of this embodiment provides a burner body, wherein a circumferentially connected fire hole channel 22 is formed inside the burner body 20, and a plurality of pot foot pieces 30 are provided along the circumference of the burner body on the outer edge.

[0265] The fire hole channel 22 is provided with a plurality of flame distribution plates 10 that are spaced apart along the circumference of the fire hole channel 22. The plurality of flame distribution plates correspond one-to-one with the positions of the plurality of pot feet plates in the radial direction of the burner body.

[0266] The flame gas distributor 10 is the flame gas distributor provided in the first aspect of this embodiment.

[0267] Furthermore, in some possible embodiments, the fire port channel 22 includes a vertical channel section 221 as an air intake section and an oblique channel section 222 as an air outlet section.

[0268] The flame distribution plate 10 is installed in the inclined channel section 222 of the flame hole channel 22.

[0269] It should be noted that the oblique channel section 222 of the flame port channel 22 is a key dimension in the burner design. In this embodiment, by setting multiple circumferentially distributed and equally high flame distribution plates 10 in the oblique channel section 222, the manufacturing process of the burner cap and burner cover can be simplified, and the dimensional accuracy of the oblique channel section 222 in the flame port channel 22 can be controlled very accurately.

[0270] Furthermore, in some possible embodiments, the burner body 20 includes a burner base 20a, a burner cover 20b, and a flame cap 20c. The burner cover 20b is arranged around the outer ring of the burner base 20a and forms an annular gas mixing chamber 21 with the burner base 20a. The flame cap 20c is arranged around the inner ring of the burner base 20a and forms a circumferentially connected flame hole channel 22 with the end of the burner cover 20b.

[0271] The burner cover 20b forms an inwardly bent edge at the end away from the inner ring of the burner seat 20a. The inwardly bent edge of the burner cover 20b and the flame cap 20c form a flame hole channel 22. The inwardly bent edge of the burner cover 20b includes a slanted portion of the burner cover and a vertical portion of the burner cover. The flame cap 20c includes a slanted portion of the flame cap and a vertical portion of the flame cap.

[0272] The inclined portion of the burner cover and the inclined portion of the flame cap together form the inclined through-and-through section 221 of the flame hole channel 22, and the vertical portion of the burner cover and the vertical portion of the flame cap together form the vertical through-and-through section 222 of the flame hole channel 22.

[0273] Furthermore, in some possible embodiments, the burner body 20 includes a burner base 20a, a burner cover 20b and a flame cap 20c, with a circumferentially connected flame hole channel 22 formed between the burner cover 20b and the flame cap 20c.

[0274] Multiple pot-foot plates 30 are spaced apart along the circumference of the burner base 20a. This prevents the flame from the fire hole channel 22 from directly interfering with the pot-foot plates 30, greatly reducing the temperature of the flue gas and the pot-foot plates, reducing heat loss, improving thermal efficiency and the durability of the pot support. At the same time, since the flame distribution plate 10 is also provided with small-hole ignition channels 101, the ignition effect is not affected while the flame is intermittent.

[0275] The third aspect of this embodiment provides a stove burner, which includes the burner body provided in the second aspect of this embodiment.

[0276] The third aspect of this embodiment also provides a stove burner, which includes a high-fire burner body and a low-fire burner body, wherein the high-fire burner adopts the burner body provided in the second aspect of this embodiment.

[0277] In summary, this embodiment provides a flame distribution plate for installation within the annular flame port channel of the burner body. The flame distribution plate includes a plate body with an ignition channel that allows a portion of the fuel-gas mixture to flow out for combustion. By dividing the flame output from the flame port channel into multiple streams, direct interference between the flame output and the burner support is avoided, significantly reducing the temperature of the flue gas and the burner support, minimizing heat loss, and improving thermal efficiency and the durability of the burner support. Simultaneously, the design of the ignition channel ensures that the intermittent flame does not affect the ignition effect, guaranteeing the stability and continuity of combustion.

[0278] Furthermore, the flame distribution plate has an arched structure, with an ignition channel formed at its bend; the top of the bend is an arc-shaped dome; a spigot structure is formed at one end of the plate along the extension direction of the ignition channel; overlapping portions are formed on both sides of the plate at the bend, the bottom surface of the overlapping portion mates with the bottom surface of the annular flame port channel, and the top surface of the bend mates with the top surface of the annular flame port channel. The arched structure and arc-shaped dome design allow the flame distribution plate to better adapt to the shape of the flame port channel, improving the matching effect between the flame distribution plate and the flame port channel, and further optimizing the flame distribution and combustion effect. The spigot structure and overlapping portion design facilitate the installation and fixation of the flame distribution plate, improving the structural stability and reliability of the burner.

[0279] Furthermore, the burner body includes a burner base, a burner cover, and a flame cap. The burner cover and burner base form a gas mixing chamber, and the ends of the flame cap and burner cover form flame port channels. The bottom surface of the overlapping part contacts and fits with the flame cap, and the top surface of the arched part contacts and fits with the burner cover. By setting a flame distribution plate between the flame cap and the burner cover, the gap between the flame port channels and the height of the flame distribution plate are kept the same, which facilitates the control of the flame port channel size, simplifies the manufacturing process of the flame cap and burner cover in the burner, and allows for very precise control of the dimensional accuracy of the flame port channels between the flame cap and the burner cover.

[0280] Furthermore, the burner body has multiple flame distribution plates spaced circumferentially along the flame port channel. These flame distribution plates correspond one-to-one with the positions of multiple pot legs in the radial direction of the burner body. This further avoids direct interference between the flame exiting the flame port channel and the pot legs, optimizes the relative positional relationship between the flame and the pot legs, further reduces the temperature of the flue gas and the pot legs, reduces heat loss, and improves thermal efficiency and the durability of the pot support.

[0281] Furthermore, the flame port channel includes a vertical channel section serving as the air inlet and an oblique channel section serving as the air outlet; the flame distribution plate is disposed in the oblique channel section of the flame port channel. The oblique channel section is a key dimension in burner design. By setting multiple circumferentially distributed flame distribution plates of equal height within the oblique channel section, the manufacturing process of the burner cap and burner cover can be simplified, and the dimensional accuracy of the oblique channel section in the flame port channel can be controlled very accurately, further optimizing combustion conditions and improving combustion efficiency and thermal efficiency.

[0282] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0283] Example 5

[0284] like Figures 5a-5c As shown, this embodiment provides a stove burner, including:

[0285] The main body of the small flame burner has a small flame hole channel 25, which includes a small flame hole channel 251 as the air inlet section and a small flame hole channel 252 as the air outlet section.

[0286] The flow area of ​​the small fire hole channel 1 251 is smaller than that of the small fire hole channel 2 252.

[0287] In this embodiment of the application, by designing the cross-sectional area of ​​the small flame hole channel 251 to be smaller than the cross-sectional area of ​​the small flame hole channel 252, the problem of flameout of the small flame hole channel can be prevented.

[0288] Furthermore, in some possible embodiments, the small flame burner body includes an annular small flame burner cover 22 located on the outer side and an annular small flame cover 21 located on the inner side. A vertically extending gap channel one is defined between the inner annular surface of the small flame burner cover 22 and the outer annular surface of the small flame cover 21, and a gap channel two is connected to the extended end of the gap channel one and extends obliquely outward.

[0289] The main body of the small flame burner also includes an annular small flame burner base 23, and at least a portion of the small flame burner base 23 is embedded in the gap channel 1.

[0290] The inner ring surface of the small flame burner base 23 embedded in the gap channel 1 is in contact with the outer ring surface of the small flame cover 21. The outer ring surface of the small flame burner base 23 and the inner ring surface of the small flame burner cover 22 define the gap channel 3. The gap channel 3 serves as the small flame hole channel 1 251 of the small flame burner body, and the gap channel 2 serves as the small flame hole channel 252.

[0291] Furthermore, in some possible embodiments, the stub burner base 23 embedded in the gap channel 1 has a machined surface, and the machined surface of the stub burner base 23 and the inner annular surface of the stub burner cover 22 define a stub fire hole channel 251.

[0292] It should be noted that the flame area and heat load of the small flame hole channel in the burner are controlled by the small flame hole channel 251. Since the small flame burner base 23 has a machined surface, its gap width is relatively easier to control. Therefore, the size of the small flame hole channel 251 defined by the small flame burner base 23 and the small flame burner cover 22 is easier to control, thereby reducing the manufacturing difficulty of the burner and improving the dimensional accuracy of the small flame hole channel 251.

[0293] It should also be noted that the small flame hole channel 252 mainly controls the direction of the small flame, i.e. the tilt angle, and the accuracy range of its gap width dimension can be relaxed.

[0294] Furthermore, in some possible implementations, the small flame burner base 23 supports the small flame cover 21 located on the inner side;

[0295] The burner also includes a main body for the large fire burner, which includes an annular base 13 for the large fire burner and supports a small fire burner cover 22 located on the outer side.

[0296] The large burner base 13 supporting the small burner cover 22 and the small burner base 23 supporting the small burner cover 21 are connected together and define the small burner gas mixing chamber 24 that is connected to the small burner fire hole channel 251.

[0297] Furthermore, in some possible embodiments, the small flame cap 21 has an outwardly bent structure, and the small flame burner cap 22 has an inwardly bent structure.

[0298] The small burner base 23 and the small burner cover 21 have an outer bending structure that fits together, while the large burner base 13 and the small burner cover 22 have an inner bending structure that fits together.

[0299] Furthermore, in some possible embodiments, the small flame cap 21 includes a first annular portion 211 extending vertically upward and a second annular portion 212 connected to the extended end of the first annular portion 211 and bent outward. The connection position of the first annular portion 211 and the second annular portion 212 constitutes the outward bending structure of the small flame cap 21.

[0300] The small burner cover 22 includes a first annular portion 221 extending vertically upward and a second annular portion 222 connected to the extended end of the first annular portion 221 and bent inward. The connection position of the first annular portion 221 and the second annular portion 222 constitutes the inward bending structure of the small burner cover 22.

[0301] Furthermore, in some possible embodiments, the second annular portion 222 of the small flame burner cover includes a downwardly inclined second annular portion A2221 of the burner cover and a second annular portion B2221 of the burner cover that is connected to the extended end of the second annular portion A2221 and extends vertically downward.

[0302] A vertically extending gap channel one is defined between the second annular portion B2222 of the burner cap and the first annular portion 211 of the flame cap, and an obliquely extending gap channel two is defined between the second annular portion A2221 of the burner cap and the second annular portion 212 of the flame cap.

[0303] Furthermore, in some possible embodiments, the small-fire gas mixing chamber 24 has a small air inlet, wherein the airflow entering the small-fire gas mixing chamber through the small air inlet can flow into the small-fire gas mixing chamber 24 in a tangential direction.

[0304] Furthermore, in some possible embodiments, the burner also includes a high-fire burner body, which includes an annular high-fire burner cover 12, an annular high-fire flame cap 11, and a disc-shaped high-fire burner base 13. An annular high-fire gas mixing chamber 14 and an annular high-fire flame hole channel 15 are defined between the high-fire burner cover 12, the high-fire flame cap 11, and the high-fire burner base 13. The high-fire gas mixing chamber 14 and the high-fire flame hole channel 15 are connected.

[0305] Furthermore, in some possible implementations, the burner also includes a gas distribution module, which includes gas distribution module one, gas distribution module two, and gas distribution module three;

[0306] in

[0307] The gas distribution module is installed in the combustion gas mixing chamber 14 to separate the gas-air mixture in the combustion gas mixing chamber 14 into upper and lower layers.

[0308] The second gas distribution module is located at the connection between the large fire gas mixing chamber 14 and the large fire vent channel 15. It is used to divide the stratified gas-air mixture in the large fire gas mixing chamber into multiple streams in the circumferential direction and guide it in the longitudinal direction into the large fire vent channel 15.

[0309] The third gas distribution module is installed inside the large fire hole channel 15 to divide the flame in the large fire hole channel 15 into multiple streams in the circumferential direction.

[0310] The gas distribution module three is positioned in the radial direction of the burner, corresponding to the burner foot cover position 60.

[0311] Furthermore, in some possible embodiments, the large-fire gas mixing chamber 14 also has a large air inlet, wherein the airflow entering the medium-large-fire gas mixing chamber 14 through the large air inlet can enter the large-fire gas mixing chamber 14 along the tangential direction of the large-fire gas mixing chamber 14.

[0312] The gas distribution module includes a C-shaped gas distribution component 40 disposed in the large fire gas mixing chamber 14. The notch of the C-shaped gas distribution component 40 corresponds to the large air inlet, that is, the notch of the C-shaped gas distribution component 40 corresponds to the mixing chamber air inlet of the large fire gas mixing chamber 14.

[0313] The second gas distribution module includes a toothed annular gas distribution component 30 located at the connection position between the large fire gas mixing chamber 14 and the large fire hole channel 15. The annular gas distribution component 30 has multiple gas distribution grooves 31 formed in its circumferential direction. The upper plate surface of the C-shaped gas distribution component 40 is lower than the top of the gas distribution groove 31, and the inner ring of the C-shaped gas distribution component 40 is spaced apart from the outer ring of the annular gas distribution component 30.

[0314] The third gas distribution module includes multiple flame gas distribution plates 50 disposed within the large fire hole channel 15. The multiple flame gas distribution plates 50 are distributed circumferentially along the large fire hole channel 15, and each flame gas distribution plate 50 is provided with an ignition channel 51 connecting the air inlet side and the air outlet side of the large fire hole channel 15.

[0315] In summary, this embodiment includes a small flame orifice channel 1 as the air inlet section and a small flame orifice channel 2 as the air outlet section. The flow area of ​​small flame orifice channel 1 is smaller than that of small flame orifice channel 2. This structural design can prevent flameout of the small flame orifice channel, improve the stability and reliability of small flame combustion, and ensure the normal operation of the burner in small flame mode.

[0316] Furthermore, the main body of the small flame burner includes an annular small flame burner cover, an annular small flame flame cap, and an annular small flame burner base. The small flame burner base is embedded in gap channel one, with its inner annular surface fitting against the outer annular surface of the small flame flame cap. Gap channel three, serving as small flame hole channel one, is defined between the outer annular surface of the small flame burner base and the inner annular surface of the small flame burner cover. Gap channel two serves as small flame hole channel two. The small flame burner base has a machined surface, and small flame hole channel one is defined between the machined surface of the small flame burner base and the inner annular surface of the small flame burner cover. Through this structural optimization, the flame area and heat load of the small flame hole channel are controlled by small flame hole channel one. Because the small flame burner base has a machined surface, its gap width is relatively easier to control, thereby reducing the manufacturing difficulty of the burner and improving the dimensional accuracy of small flame hole channel one. Small flame hole channel two mainly controls the direction of the small flame, i.e., the tilt angle, and its gap width accuracy range can be widened, further simplifying the manufacturing process.

[0317] Furthermore, the main body of the high-fire burner includes an annular burner cover, an annular flame cap, and a disc-shaped burner base. The burner cover, flame cap, and burner base define an annular combustion gas mixing chamber and an annular flame orifice channel, which are interconnected. This forms a complete main body structure for the high-fire burner, providing favorable conditions for combustion and ensuring its stability and efficiency.

[0318] Furthermore, the burner also includes a gas distribution module, comprising three modules: Gas Distribution Module 1, Gas Distribution Module 2, and Gas Distribution Module 3. Gas Distribution Module 1 is located within the main combustion chamber to separate the gas-air mixture into upper and lower layers. Gas Distribution Module 2 is located at the connection point between the main combustion chamber and the main combustion orifice channel, and is used to circumferentially divide the stratified gas-air mixture within the main combustion chamber into multiple streams, then guide it longitudinally into the main combustion orifice channel. Gas Distribution Module 3 is located within the main combustion orifice channel to circumferentially divide the flame within the channel into multiple streams. The gas distribution modules further optimize the distribution and flow of the gas-air mixture, improving combustion efficiency and thermal efficiency, resulting in more complete and uniform combustion, reduced flue gas content, and improved environmental performance of the burner. The placement of Gas Distribution Module 3 in the radial direction of the burner corresponds to the position of the burner's foot cover, preventing interference between the flame and the foot cover, reducing the foot cover temperature, minimizing heat loss, and improving thermal efficiency and the durability of the burner support.

[0319] Furthermore, the large-fire gas mixing chamber also has a large air inlet, through which the incoming airflow can flow into the large-fire gas mixing chamber along the tangential direction; the first gas distribution module includes a C-shaped gas distribution component installed in the large-fire gas mixing chamber, with the notch of the C-shaped gas distribution component corresponding to the large air inlet; the second gas distribution module includes a toothed annular gas distribution component installed at the connection position between the large-fire gas mixing chamber and the large-fire fire hole channel, with multiple gas distribution grooves formed in its circumferential direction, the upper plate surface of the C-shaped gas distribution component being lower than the top of the gas distribution groove, and the inner ring of the C-shaped gas distribution component being spaced apart from the outer ring of the annular gas distribution component; the third gas distribution module includes multiple flame gas distribution plates installed in the large-fire fire hole channel, with the multiple flame gas distribution plates distributed along the circumference of the large-fire fire hole channel, and each flame gas distribution plate having an ignition channel connecting the air inlet side and the air outlet side of the large-fire fire hole channel. By using the tangential air intake method of the combustion chamber and the reasonable coordination of the gas distribution module, the mixing effect between gas and air is further improved, the flow direction and distribution of the gas mixture are optimized, the combustion is more complete and stable, the combustion efficiency and thermal efficiency are further improved, the flue gas content is reduced, and the environmental performance of the burner is improved.

[0320] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0321] Example 6

[0322] like Figures 6a-6c As shown, the first aspect of this embodiment provides an energy-saving disc 70, which is arranged around the burner body of a stove burner and is used to cooperate with the pot foot piece 60 of the stove burner, wherein the energy-saving disc 70 includes:

[0323] The annular radiating disk 71 and the annular tray 72 are arranged vertically, with the annular radiating disk 71 located above the annular tray 72;

[0324] The radiant plate 71 has radiant plate perforations, and the tray 72 has tray perforations. The radiant plate perforations and the tray perforations are arranged vertically and vertically to allow the pot foot pieces 60 to pass through.

[0325] The radiant disc 71 and the tray 72 are configured such that when the foot plate passes through the annular radiant disc 71 and the annular tray 72 and is engaged with the burner body, the radiant disc 71 and the tray 72 can remain in contact with each other.

[0326] In this embodiment, by setting the radiant plate 71 and the tray 72 of the supporting pot foot piece 60 to not contact each other, the heat conduction and diffusion of the radiant plate 71, which is closest to the flame, can be reduced, and more heat radiation can be radiated to the cookware, thereby improving thermal efficiency.

[0327] Furthermore, in some possible embodiments, one of the radiant plate 71 and the tray 72 is used to weld together with the foot piece 60, and the other is used to snap together with the foot piece 72.

[0328] In this embodiment, when the radiant plate 71 and the tray 72 are installed together with the pot foot piece 60, they can be fixed together with the pot foot piece 60 by welding and / or snap-fitting, and the fixed radiant plate 71 and the tray 72 can still not contact each other.

[0329] Furthermore, in some possible embodiments, the pot foot piece 60 includes a pot foot piece head for supporting the pot and a pot foot piece support foot connected to the bottom end of the pot foot piece head and extending downward.

[0330] The upper surface of the radiant plate 71 is used to weld to the lower end of the head of the pot foot piece, and / or the radiant plate perforation of the radiant plate 71 is used to weld to the pot foot piece support foot.

[0331] The tray 72 has a snap-fit ​​structure at the tray perforation position, and the pot foot piece support has a snap-fit ​​79. The snap-fit ​​structure can be snapped into the snap-fit ​​79 of the pot foot piece support when the pot foot piece 60 is inserted through the tray perforation, so as to fix the tray 72 and the pot foot piece 60 through the snap-fit ​​structure and the snap-fit ​​79.

[0332] Furthermore, in some possible embodiments, the snap-fit ​​structure includes a spring piece 74 disposed at the perforation position of the tray, and the snap-fit ​​opening 79 is a notch recessed on the outer periphery of the foot support.

[0333] When the pot foot support is inserted through the tray through the hole from top to bottom, the bottom end of the pot foot support can press down on the spring piece 74 to make the spring piece 74 elastically deform. When the pot foot support moves to the position corresponding to the slot 79 and the spring piece 74, the spring piece 74 can be reset under its own elastic action and locked into the slot 79 of the pot foot support.

[0334] Furthermore, in some possible embodiments, the inner side of the energy-saving disc 70 and the outer side of the burner body are fitted together with a gap to form an outer secondary air supply channel 76. In this way, when the burner is in use, the outer secondary air supply channel 76 can supply air to the flame in the burner hole channel from the outside of the burner hole channel to improve the combustion effect of the burner.

[0335] Furthermore, in some possible implementations, the outer secondary air supply channel 76 is designed as an inclined channel extending upward from the outside to the inside, with the inlet width of the outer secondary air supply channel 76 on the outside being x2 and the outlet width of the outer secondary air supply channel 76 on the inside being x1.

[0336] Where x2 ≥ x1.

[0337] In this embodiment, the inlet width x2 of the outer secondary air replenishment channel 76 is designed to be greater than or equal to the outlet width x1 of the outer secondary air replenishment channel, which makes the air intake of the outer secondary air replenishment channel 76 smoother.

[0338] Furthermore, in some possible implementations, the outer secondary air supply channel 76 is designed as a tapering inclined channel that extends upwards from the outside to the inside.

[0339] or

[0340] The outer secondary air supply channel 76 is designed as an equally spaced inclined channel that extends upwards from the outside to the inside.

[0341] Furthermore, in some possible implementations, the air intake direction of the outer secondary air replenishment channel 76 forms an angle α with the horizontal plane;

[0342] The outlet direction of the outer secondary air supply channel 76 forms an angle b with the horizontal plane.

[0343] Where a ≥ b.

[0344] Furthermore, in some possible embodiments, the radiating disk 71 includes a first annular portion 711 of the radiating disk extending obliquely upward from the inside to the outside;

[0345] The tray 72 includes a first annular portion 721 of the tray that extends downward at an angle from the inside out;

[0346] The inner side of the first annular portion 721 of the tray is located below the inner side of the first annular portion 711 of the radiant disk. An outer secondary air supply channel 76 is defined between the first annular portion 721 of the tray and the outer side of the burner body. An outlet channel communicating with the outer secondary air supply channel 76 is defined between the inner edge of the first annular portion 711 of the radiant disk and the outer side of the burner body.

[0347] That is, the outer secondary air supply channel 76 in this embodiment is obtained by the cooperation between the two components, the radiant disk 71 and the tray 72, and the main body of the burner, without the need to make holes or slots in the components to achieve the function of secondary air supply.

[0348] Furthermore, in some possible embodiments, the downward slope k1 of the first annular portion 721 of the tray satisfies the following: when the first annular portion 721 of the tray and the outer side of the burner body are fitted together with a gap, an outer secondary air supply channel 76 can be defined between them in a gradually narrowing or equally spaced manner from the outside to the inside.

[0349] Furthermore, in some possible embodiments, the tray 72 also includes a second annular portion 722 of the tray, which is disposed at the extended end of the first annular portion 721 of the tray and extends obliquely upward. The outer side of the burner body includes an inclined outer annular surface 77 of the burner body for clearance fitting with the first annular portion 721 of the tray and a vertical outer annular surface 78 of the burner body formed at the extended end of the inclined outer annular surface 77 of the burner body and continuing to extend downward.

[0350] The length L of the downwardly extending first annular portion 721 of the tray satisfies the following: when the first annular portion 721 of the tray and the inclined outer annular surface 77 of the burner body are fitted together with a gap, the downward extension line of the second annular portion 722 of the tray can intersect with the vertical outer annular surface 78 of the burner body. This setting makes the internal structure of the burner invisible from the user's perspective, thus making the appearance of the burner cleaner.

[0351] As can be seen, by designing the slope k and length L of the first annular portion 721 of the tray in this embodiment, the appearance of the burner can be made neater and more beautiful, and the combustion effect of the burner can be improved. {Because the first annular portion 721 of the tray can define a gradually narrowing or equally spaced outer secondary air replenishment channel 76 that extends upward from the outside to the inside between the main body of the burner}.

[0352] Furthermore, in some possible embodiments, the burner body includes a burner base 13 and a flame cap 11 and a burner cover 12 disposed on the burner base 13 and fitted together internally and externally. A gas mixing chamber 14 and a flame hole channel 15 are connected between the burner base 13, the flame cap 11 and the burner cover 12.

[0353] The burner cover 12 includes a downwardly inclined annular surface extending from the inside to the outside, and the burner base 13 includes a downwardly inclined annular surface extending from the inside to the outside. The bottom end of the burner cover inclined annular surface is connected and engaged with the top end of the base inclined annular surface.

[0354] The inclined annular surface of the burner cover, as part of the inclined outer annular surface 77 of the burner body, is fitted together with the first annular portion 721 of the tray with a gap, and the inclined annular surface of the base, as another part of the inclined outer annular surface 77 of the burner body, is fitted together with the first annular portion 721 of the tray with a gap.

[0355] The base inclined ring 77 has a pot foot piece slot 131 for the pot foot piece 60 to be inserted.

[0356] Furthermore, in some possible embodiments, the radiating disk 71 includes, from the inside out, a first annular portion 711, a second annular portion 712, and a third annular portion 713.

[0357] The first annular portion 711 of the radiating disk extends upward at an angle from the inside to the outside, the second annular portion 712 extends horizontally, and the third annular portion 713 extends upward at an angle from the inside to the outside.

[0358] Furthermore, in some possible implementations, the energy-saving disk 70 also includes:

[0359] The annular reflector 73 is located within the mounting space enclosed by the upper radiating disk 71 and the lower tray 72.

[0360] The reflector plate 73 has a perforation for the foot plate 60 to pass through.

[0361] In this embodiment, by setting a reflector 73 between the radiant plate 71 and the tray 72, the heat conduction and diffusion of the radiant plate 71, which is closest to the flame, can be further reduced downward, thereby allowing more heat to radiate upward to the cookware and improving the thermal efficiency of the burner.

[0362] Furthermore, in some possible embodiments, the reflector 73 has an inner low and outer high structure. The reflector 73 includes, from the inside to the outside, a first annular portion 731, a second annular portion 732, and a third annular portion 733. The first annular portion 731 extends upward at an angle from the inside to the outside, the second annular portion 732 extends horizontally from the inside to the outside, and the third annular portion 733 extends upward at an angle from the inside to the outside.

[0363] The inner sides of the first annular portion 731 of the reflector, the inner sides of the first annular portion 711 of the radiator, and the inner sides of the first annular portion 721 of the tray cooperate with each other, and the outer sides of the third annular portion 733 of the reflector, the outer sides of the third annular portion 713 of the radiator, and the outer sides of the second annular portion 722 of the tray cooperate with each other.

[0364] The second aspect of this embodiment provides a burner body that includes the energy-saving disc provided in the first aspect of this embodiment.

[0365] The third aspect of this embodiment provides a stove burner, which includes a pot foot plate and the burner body provided in the second aspect of this embodiment.

[0366] The third aspect of this embodiment also provides a stove burner, which includes a large-flame burner body and a small-flame burner body, wherein the large-flame burner body adopts the burner body provided in the second aspect of this embodiment.

[0367] Furthermore, in some possible embodiments, the pot foot piece 60 includes a pot foot piece head for supporting the pot and a pot foot piece support foot connected to the bottom end of the pot foot piece head and extending downward.

[0368] The radiating disk 71 includes, from the inside out, a first annular portion 711, a second annular portion 712, and a third annular portion 713.

[0369] The first annular portion 711 of the radiating disk extends upwards at an angle from the inside out; the second annular portion 712 extends horizontally; and the third annular portion 713 extends upwards at an angle from the inside out.

[0370] The second annular portion 712 and the third annular portion 713 of the radiant disk are both used to mate with the head of the pot foot piece. After mating, the top of the head of the pot foot piece can be higher than the top of the third annular portion 713 of the radiant disk, and the distance between the two is x3.

[0371] The distance x3 between the top of the head of the foot plate and the top of the third annular part 713 of the radiant disk is greater than the channel outlet width x1 of the outer secondary air replenishment channel 76.

[0372] In this embodiment, the distance x3 between the top of the head of the pot foot piece and the top of the third annular part of the radiant disk is set to be greater than the channel outlet width x1 of the outer secondary air replenishment channel. This allows the air in the outer secondary air replenishment channel 76 to be effectively discharged, avoiding the outer secondary air replenishment channel 76 from encountering greater resistance when replenishing air.

[0373] Furthermore, in some possible implementations, the inner side of the energy-saving disc 70 and the outer side of the burner body are fitted together with a gap to form an outer secondary air supply channel 76.

[0374] The burner body is also provided with a foot plate slot 131, and the foot plate 60 is inserted into the foot plate slot 131 of the burner body through the foot plate insertion port of the energy-saving plate 70.

[0375] The pot foot piece 60, which is inserted into the pot foot piece slot 131, passes through the outer secondary air supply channel 76 so that the heat on the pot foot piece 60 can be carried away by the air flow of the outer secondary air supply channel.

[0376] In summary, the energy-saving plate in this embodiment includes an annular radiant plate and an annular tray arranged vertically, which do not contact each other. This reduces the downward conduction and diffusion of heat from the radiant plate, which is closest to the flame, allowing more heat to radiate to the cookware and improving thermal efficiency.

[0377] Furthermore, the radiant plate and tray are fixed to the pot feet by welding and / or snap-fitting. This ensures a stable connection between the energy-saving plate and the pot feet while maintaining the separation between the radiant plate and the tray, further optimizing thermal efficiency.

[0378] Furthermore, the inner side of the energy-saving disc is fitted with the outer side of the burner body to form an outer secondary air supply channel. The channel is designed as a gradually narrowing or equally spaced inclined channel extending upwards from the outside to the inside, and the inlet width of the channel is greater than or equal to the outlet width of the channel. This allows air to be supplied to the flame outside the burner channel, improving combustion efficiency while ensuring smooth air supply, further optimizing combustion efficiency and thermal efficiency.

[0379] Furthermore, a reflector is placed between the radiant plate and the cooktop, with the reflector having a lower inner surface and a higher outer surface. This further reduces the downward conduction and diffusion of heat from the radiant plate, allowing more heat to radiate upwards to the cookware, thus further improving thermal efficiency.

[0380] Furthermore, the burner body includes a burner base, a flame cap, and a burner cover, forming an interconnected gas mixing chamber and flame port channel; the inclined annular surface of the burner cover is fitted with the first annular portion of the tray with a clearance. This forms a complete burner body structure, providing favorable conditions for combustion, and in conjunction with the energy-saving disc, optimizing combustion efficiency and thermal efficiency.

[0381] Furthermore, the foot plates are inserted into the foot plate slots of the burner body through the foot plate insertion ports of the energy-saving plate, and the foot plates pass through the outer secondary air supply channel. The airflow in the outer secondary air supply channel can be used to carry away the heat on the foot plates, further optimizing thermal efficiency, while ensuring a stable connection between the foot plates and the burner body.

[0382] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0402] The third aspect of this embodiment also provides a stove burner, which is provided with a large-fire burner body and a small-fire burner body, wherein the large-fire burner body adopts the burner body provided in the second aspect of this embodiment.

[0403] Furthermore, in some possible embodiments, the pot foot piece 60 includes a pot foot piece head for supporting the pot, and a pot foot piece support foot disposed at the bottom end of the pot foot piece head and extending downward.

[0404] When the foot support is inserted into the foot through hole on the energy-saving cover 801, the head of the foot is located above the energy-saving cover 801, and there is a distance between the lower end face of the foot head and the upper cover surface of the energy-saving cover 801.

[0405] Furthermore, in some possible implementations,

[0406] The pot foot support is welded together with the energy-saving cover 801 in the energy-saving device 80;

[0407] and / or

[0408] The pot foot support is welded together with the energy-saving cover tray 802 in the energy-saving device 80.

[0409] Furthermore, in some possible embodiments, multiple pot foot pieces are provided, and the multiple pot foot pieces are distributed circumferentially at intervals on the energy-saving device 80, and a channel is formed between two adjacent pot foot pieces 60 and the upper plate surface of the energy-saving device 80.

[0410] When the pot foot plate 60 supports the pot, the channel can form an outer secondary air supply channel with the bottom of the pot, which is used to supply air to the burner outlet.

[0411] Furthermore, in some possible embodiments, the burner body is formed with a flame port channel 15, wherein the highest position of the energy-saving device 80 disposed on the burner body is lower than the flame outlet position of the flame port channel 15.

[0412] Furthermore, in some possible embodiments, the burner body includes an annular burner base 13, an annular burner cover 12, and an annular flame cap 11, with a gas mixing chamber 14 and a flame hole channel 15 connected between the burner base 13, the burner cover 12, and the flame cap 11.

[0413] The inclined ring surface of the burner base 13 and the inclined ring surface of the burner cover 12 are connected together to form the inclined outer ring surface 77 of the burner body. The inclined ring surface of the energy-saving cover tray 802 is matched with the inclined ring surface of the burner base 13. The inclined ring surface of the energy-saving cover 801 is matched with the inclined ring surface of the burner cover 12.

[0414] The burner base 13 also includes a vertical annular surface formed at the bottom of the inclined portion of the burner base and extending downward, the vertical annular surface of the burner base engaging with the vertical annular surface of the energy-saving cover tray.

[0415] Furthermore, in some possible embodiments, the energy-saving cover tray 802 and the burner base 13 are fixed together by locking member 79, and the energy-saving cover 801 is welded to the energy-saving cover tray 802 as a separate component;

[0416] or

[0417] The energy-saving cover tray 802 and the burner base 13 are fixed together by the locking member 79. The energy-saving cover 801 is an integral cover structure with the burner base 13 and is welded together with the energy-saving cover tray 802.

[0418] It should be noted that this specification describes in detail several embodiments of the present invention, totaling seven. These embodiments demonstrate the diversity and practicality of the present invention from different perspectives. Among them, the technical solutions involved in embodiments 1 to 5 are independent of each other and highly compatible, and can be arbitrarily combined according to actual application needs to achieve better usage effects and functional expansion.

[0419] However, it should be specifically pointed out that the energy-saving panel solution in Embodiment 6 and the energy-saving cover solution in Embodiment 7 are parallel independent technical solutions. They are mutually exclusive in structure and function and cannot be applied to the same product or system at the same time. In other words, when the energy-saving panel solution of Embodiment 6 is combined with one or more of Embodiments 1-5, the energy-saving cover solution of Embodiment 7 cannot be used at the same time, and vice versa.

[0420] In summary, embodiments 1 to 5 of this utility model can be freely combined, while embodiments 6 and 7 are mutually exclusive independent solutions. Those skilled in the art can flexibly select and apply the technical solutions in the above embodiments according to specific application scenarios and target needs, so as to fully leverage the technical advantages and innovative value of this utility model.

[0421] It should be noted that when the solutions in Examples 1-5 are combined, the resulting stove burner can achieve a heat load of 5.2kW, a CO concentration in dry flue gas ≤0.042%, and a thermal efficiency of 68.4%. However, GB16410-2020 "Household Gas Stoves" stipulates that built-in gas stoves require a thermal efficiency ≥55% and a CO concentration in dry flue gas ≤0.05%. GB30720-2014 "Energy Efficiency Limits and Energy Efficiency Grades for Household Gas Stoves" stipulates that the energy efficiency of a Grade 1 built-in gas stove is 63%.

[0422] It should be further noted that when the solutions in Examples 1-5 are combined together and the energy-saving panel solution in Example 6 is added, the resulting stove burner can achieve a heat load of 5.2kW, a CO concentration in dry flue gas of ≤0.0075%, and a thermal efficiency of 79.2%, which further improves the various performance indicators of the burner.

[0423] It should be further noted that when the solutions in Examples 1-5 are combined together and the energy-saving cover solution in Example 7 is added, the burner can achieve a heat load of 5.2kW, a CO concentration in dry flue gas of ≤0.0273%, and a thermal efficiency of 70.5%, which further improves the various performance indicators of the burner.

[0424] In summary, the energy-saving device in this embodiment includes an annular energy-saving cover with perforations for inserting the pot legs. When the pot legs are inserted into the perforations on the energy-saving cover, the heads of the pot legs are positioned above the cover. This reduces the downward transfer and diffusion of heat from the heads of the pot legs, allowing more heat to radiate upwards to the bottom of the pot above the heads of the pot legs, thus improving the thermal efficiency of the burner.

[0425] Furthermore, the energy-saving device also includes an annular energy-saving cover tray located below the energy-saving cover; the energy-saving cover and the energy-saving cover tray are spaced apart vertically and enclose a heat-insulating cavity. The energy-saving cover tray and the energy-saving cover have corresponding perforations for the pot feet to pass through. When the pot feet are inserted through the perforations, the pot feet support the pot feet through the heat-insulating cavity. Through the formed closed heat-insulating cavity, the downward conduction and diffusion of heat from the energy-saving cover, which is closest to the flame, is reduced, allowing more heat to radiate upwards to the cookware, further improving the thermal efficiency of the burner.

[0426] Furthermore, the inner ring side of the energy-saving cover tray and the inner ring side of the energy-saving cover are fixedly fitted together; and / or the outer ring side of the energy-saving cover tray and the outer ring side of the energy-saving cover are fixedly fitted together. This enhances the overall structural stability of the energy-saving device and ensures the stability and insulation effect of the insulation cavity.

[0427] Furthermore, the burner body includes an inclined outer ring surface extending downwards from the inside out; the energy-saving device includes an inclined inner ring surface extending downwards from the inside out, for mating with the inclined outer ring surface of the burner body. This allows for a good fit between the energy-saving device and the burner body, optimizing the overall structure and performance of the burner.

[0428] Furthermore, the foot support is welded to the energy-saving cover in the energy-saving device; and / or the foot support is welded to the energy-saving cover tray in the energy-saving device, which can ensure a stable connection between the foot support and the energy-saving device and further optimize thermal efficiency.

[0429] Furthermore, the pot feet are provided in multiple pieces, which are distributed circumferentially around the energy-saving device. A channel is formed between two adjacent pot feet and the upper plate of the energy-saving device. When the pot feet support the pot, the channel can form an outer secondary air supply channel with the bottom of the pot, which is used to supply air to the burner outlet. This design can provide air supply to the burner outlet, optimize combustion conditions, and improve combustion efficiency and thermal efficiency.

[0430] In summary, through the above series of structural optimizations and improvements, the combustion efficiency, thermal efficiency, and environmental performance of the stove burner have been significantly improved, meeting users' needs for high-efficiency and energy-saving gas stoves while reducing energy consumption and pollutant emissions, resulting in good economic and social benefits.

[0431] Example 8

[0432] Embodiment 8 of this application provides a gas stove burner, such as Figures 8a-8l As shown, the gas stove burner in this embodiment mainly consists of the following modules. These modules, when combined, can form a gas stove burner with superior combustion performance. Specifically, the module distribution and composition of the burner are as follows:

[0433] I. Main Burner Module

[0434] The main burner module includes a large fire ejector tube 10 and a large fire burner module;

[0435] The large-fire burner module includes an annular large-fire cover 11, an annular large-fire burner cover 12, and a disc-shaped large-fire burner base 13; the large-fire burner base 13, the large-fire burner cover 12, and the large-fire cover 11 form a connected large-fire gas mixing chamber 14 and a large-fire hole channel 15; the large-fire ejector tube 10 is formed at the bottom of the large-fire burner base 13, and the large-fire ejector tube 10 can inject gas-air mixture into the large-fire gas mixing chamber 14 along the tangential direction of the large-fire gas mixing chamber 14;

[0436] The end of the large fire burner cover 12 away from the large fire burner base 13 and the end of the large fire cover 11 away from the large fire burner base 13 are fitted together to form a uniform and circumferentially connected annular gap, which serves as the large fire hole channel 15 of the large fire burner module.

[0437] Furthermore, the large fire hole channel 15 has an upper opening and a lower opening in its fire outlet direction. The lower opening serves as the inlet end of the gas-air mixture, with its opening facing downwards and communicating with the large fire gas-air mixture chamber 14. The upper opening serves as the outlet end of the gas-air mixture, forming a complete circle of large fire holes with its opening facing upwards. The gas-air mixture in the large fire gas-air mixture chamber 14 enters from the lower opening of the large fire hole channel 15 and exits from the large fire hole at the upper opening.

[0438] Furthermore, the end of the large fire burner cover 12 near the large fire burner base 13 is sealed to the outer ring stepped surface of the large fire burner base 13 (preferably riveted), and the end of the large fire cover 11 near the large fire burner base 13 is sealed to the inner ring of the large fire burner base 13.

[0439] Furthermore, the inner part of the large fire burner cover 12 is higher than the outer part. The large fire burner cover 12 has a first bent edge that bends downward at the high point, and the large fire cover 11 has a second bent edge that bends outward at the high point. The first bent edge and the second bent edge define a large fire hole channel 15 that bends outward.

[0440] II. Auxiliary Combustion Module

[0441] The auxiliary burner module includes a pilot flame injector 20 and a pilot flame burner module;

[0442] The small flame burner module includes an annular small flame cover 21, an annular small flame burner cover 22, and a disc-shaped small flame burner base 23. The annular small flame cover 21, the annular small flame burner cover 22, and the disc-shaped small flame burner base 23 form an interconnected small flame gas mixing chamber 24 and a small flame orifice channel 25. A gap is formed between the auxiliary burner module located on the inner side and the main burner module located on the outer side. This gap serves as a secondary air supply channel 26 in the middle of the burner. The secondary air supply channel 26 is used to supply air to the flame inside the main flame orifice channel 15 and to supply air to the flame outside the small flame orifice channel 25, so as to make the gas combustion of the main burner module and the auxiliary burner module more complete.

[0443] Furthermore, the small burner base 23 and the large burner base 13 are sealed together, with the parting surface being the centerline plane of the ejector tubes {large burner ejector tube 10 and small burner ejector tube 20}, and fastened with screws. The small burner cover 22 is riveted to the large burner base 13, and the small burner cover 21 is riveted to the small burner base 23.

[0444] Furthermore, the small flame burner base 23 and the small flame burner cover 22 form a uniform small flame hole channel 1 251, which connects to the small flame gas mixing chamber 24. The small flame cover 21 and the small flame burner cover 22 form a uniform small flame hole channel 252, which connects to form a small flame hole channel 25. The hollow part of the small flame cover 21 is an inner secondary air supply channel 27, which is used to supply air to the flame inside the small flame hole channel 25.

[0445] It should be noted that in this embodiment, the cross-sectional area of ​​the second small flame hole channel 252 is set to be larger than the cross-sectional area of ​​the first small flame hole channel 251, so as to prevent the problem of flameout.

[0446] It should be further explained that the flame area and heat load of the small flame hole channel 25 are controlled by the small flame hole channel 251. Since the small flame burner base 23 has a machined surface, its gap width is relatively easier to control. Therefore, the size of the small flame fire control channel 251 formed by the small flame burner base 23 and the small flame burner cover 22 is easier to control, thus making it easier to control the flame area and heat load of the small flame hole channel 25 to meet the flame requirements.

[0447] It should be further noted that the second flame hole channel 252 mainly controls the flame direction, i.e., the tilt angle, and the dimensional accuracy range of its gap width can be relaxed. This reduces the manufacturing difficulty and improves the circumferential gap accuracy. Therefore, the gap between the small flame cover 21 and the small flame burner cover 22 can meet the dimensional requirements of the second flame hole channel 252.

[0448] III. Gas Distribution Module 1

[0449] In this embodiment, the gas distribution module 1 includes an annular gas distribution component 30 disposed in the large fire gas mixing chamber 14, and the annular gas distribution component 30 is provided with a plurality of gas distribution grooves 31 along its circumference.

[0450] The gas distribution groove 31 is located below the first bent edge of the burner cover 12 and connects the combustion gas mixing chamber 14 and the combustion fire hole channel 15. Preferably, the gas distribution groove 31 is a vertically extending strip-shaped groove structure. The gas in the combustion gas mixing chamber 14 is separated by multiple gas distribution grooves 31 on the annular gas distributor 30 and discharged into the combustion fire hole channel 15. This can divide the gas-air mixture that enters the combustion gas mixing chamber 14 tangentially into multiple streams and discharge them vertically into the combustion fire hole channel 15 to improve the injection capability, make the combustion flame pattern (annular thin flame) more standardized, and reduce the flue gas content.

[0451] Furthermore, the lower end of the first bent edge of the large-fire burner cover 12 has a certain axial gap with the upper end of the gas distribution groove 31, that is, the lower end of the first bent edge of the large-fire burner cover 12 and the upper end of the gas distribution groove 31 are spaced apart. This can further enhance the air intake capacity of the large-fire injector 10, thereby further reducing the flue gas content of the burner.

[0452] IV. Gas Distribution Module Two

[0453] The second gas distribution module in this embodiment includes a C-shaped gas distribution component 40 disposed in the combustion chamber 14. It should be noted that the C-shape mentioned in this embodiment does not require a perfect C-shape; it only needs to be roughly C-shaped. In other words, the gas distribution plate in this embodiment can be understood as a ring-shaped plate with a notch in the circumferential direction. The gas distribution plate 40 divides the combustion chamber 14 into an upper combustion chamber and a lower combustion chamber in the vertical direction. The C-shaped gas distribution component 40 has legs 41, and the bottom of the combustion chamber 14 has slots corresponding to these legs 41. The empty portion of the C-shaped gas distribution component 40 corresponds to the outlet position of the combustion ejector tube 10 connecting to the combustion chamber 14, so that the gas distribution within the combustion chamber 14 is more uniform, and the combustion of the exhaust gas reduces the flue gas content. It should be noted that in this embodiment, the reason why the missing part of the C-shaped gas distributor 40 corresponds to the outlet position of the large fire ejector pipe 10 connecting the large fire gas mixing chamber 14 is to avoid the gas-air mixture discharged from the large fire ejector pipe 10 being greatly blocked by the C-shaped gas distributor 40, so as to ensure the air intake of the large fire gas mixing chamber 14 while making the gas-air mixture in the large fire gas mixing chamber 14 more uniform.

[0454] Furthermore, in this embodiment, the height of the C-shaped gas distributor 40 is set to be lower than the height of the top of the gas distributor 31. In this way, the gas-air mixture in the upper high-fire gas mixing chamber and the gas-air mixture in the lower high-fire gas mixing chamber can both enter the strip-shaped gas distributor 31 laterally and be discharged vertically into the high-fire ignition channel 15. Preferably, in this embodiment, the C-shaped gas distributor 40 is set at the middle position of the height of the gas distributor 31, so that the gas-air mixture in the upper high-fire gas mixing chamber and the gas-air mixture in the lower high-fire gas mixing chamber are more evenly distributed.

[0455] Furthermore, there is a certain circumferential gap between the inner edge of the C-shaped gas distributor 40 and the outer edge of the gas distribution groove 31. That is, the C-shaped gas distributor 40 and the gas distribution groove 31 are spaced apart in the radial direction of the burner, which can enhance the air intake capacity of the large flame injector 10 and reduce the flue gas content.

[0456] V. Gas Distribution Module Three

[0457] In this embodiment, the gas distribution module three includes a flame gas distribution plate 50 disposed in the large fire hole channel 15. The large fire hole channel 15 includes a large fire hole channel one 151 that extends vertically and is connected to the large fire gas mixing chamber 14, and a large fire hole channel two 152 that is connected to the large fire hole channel one 151 and extends outward at an angle. Preferably, the flame gas distribution plate 50 is disposed in the large fire hole channel two 152.

[0458] The burner base 13 has multiple foot plate slots 131, preferably four, evenly distributed around the circumference of the burner base 13. The number of flame distribution plates 50 corresponds to the number of foot plate slots 131. The flame distribution plate 50 is an arched structure, welded to the burner cover 12 of the second flame hole channel 152, with a small hole in the middle (serving as an ignition channel 51). The air inlet end of the ignition channel 51 connects to the first flame hole channel 151. The burner cover 11 rests on the upper arched surface of the flame distribution plate 50 (the height of the flame distribution plate 50 is equal to the width of the gap in the flame hole channel 15). Foot plates 60 are inserted into the foot plate slots 131.

[0459] Multiple flame distribution plates 50 divide the flame in the large fire hole channel 152 into multiple segments, intermittently burning the flame without affecting the ignition. (Because small holes 51 are provided on the flame distribution plates 50, the separated flames can be reintroduced to the outside of the large fire hole channel 15.) At the same time, since the flame distribution plates 40 are arranged radially to correspond to the foot plate 60, interference between the flame and the foot plate 60 can be avoided, thereby greatly reducing the temperature of the flue gas and the foot plate 60, reducing heat loss, improving thermal efficiency and the durability of the foot plate 60.

[0460] The burner cover 12 has a corresponding flame distribution plate positioning groove 121, and the flame distribution plate 50 is set in the flame distribution plate positioning groove 121 and preferably welded and fixed together with the burner cover 12.

[0461] It should be noted that the gap width of the second flame hole channel 152 is a critical dimension. This application simplifies the manufacturing process and can control the dimensional accuracy of the second flame hole channel 15 very accurately by setting flame distribution plates 50 of equal height inside the second flame hole channel 15. In layman's terms, by setting multiple flame distribution plates 50 of equal height in this application, the dimensions of the second flame hole channel 152 formed by the burner cover 12 and the burner cover 11 can be precisely controlled.

[0462] It should also be noted that the applicant found that reducing the burner height (i.e., the height from the top of the burner foot plate to the burner cap) can improve thermal efficiency, but it will increase the flue gas emission content. Flue gas emission content and thermal efficiency have a certain inverse relationship. Through the above measures, the flue gas emission content of the burner combustion is significantly reduced, far below the national standard requirements. The burner height can be reduced, and the flue gas emission content can be appropriately increased and controlled within the standard range, while simultaneously improving the thermal efficiency of the burner.

[0463] Specifically, in this embodiment, by making the aforementioned improvements to the burner, a heat load of 5.2kW, a CO concentration in dry flue gas ≤0.042%, and a thermal efficiency of 68.4% can be achieved. However, GB16410-2020 "Household Gas Stoves" stipulates that built-in gas stoves must have a thermal efficiency ≥55% and a CO concentration in dry flue gas ≤0.05%. GB30720-2014 "Energy Efficiency Limits and Energy Efficiency Grades for Household Gas Stoves" stipulates that the energy efficiency of a Grade 1 built-in gas stove must be 63%.

[0464] As can be seen, by making the above-mentioned improvements to the burner in the embodiments of this application, the various performance indicators of the burner can far exceed the performance indicators stipulated by the state.

[0465] VI. Energy-saving module

[0466] Furthermore, in this embodiment, in order to further improve the various performance indicators of the burner, an energy-saving module is also provided. The energy-saving module includes an energy-saving disk 70 arranged around one side of the burner, and the energy-saving disk 70 is provided with pot foot plate through holes for the pot foot plates to pass through.

[0467] Specifically, the energy-saving tray in this embodiment includes a double-layer or triple-layer energy-saving tray. The double-layer tray includes a radiant tray 71 that radiates heat to the cookware and a tray 72. The triple-layer tray further includes a reflector 73 located between the radiant tray 71 and the tray 72. The radiant tray 71 does not contact the outer surfaces of the reflector 73 and the tray 72, reducing the downward conduction and diffusion of heat from the radiant tray 71, which is closest to the flame, and allowing more heat to radiate to the cookware or pot above, thus improving thermal efficiency. The radiant tray 71, reflector 73, and tray 72 all have perforations for pot feet 60, which sequentially pass through these perforations. The pot feet 60 are welded to the radiant tray 71. The tray 72 and the foot piece 60 are fastened together. A spring clip 74 is provided at the foot piece slot of the tray 72. The foot piece 60 has a corresponding notch 75. When the foot piece 60 is inserted into the tray 72, its lower end first pushes open the spring clip 74. As it continues to be inserted into the notch 75, the spring clip 74 slides into the notch 75, securing the foot piece 60 to the tray 72. The lower end of the foot piece 60 is inserted into the foot piece slot 131 on the burner base 13.

[0468] Experimental verification shows that the burner with a three-layer energy-saving disc in this embodiment can achieve a heat load of 5.2kW, a CO concentration of ≤0.0075% in dry flue gas, and a thermal efficiency of 79.2%, further improving the various performance indicators of the burner.

[0469] Of course, in some possible implementations, the energy-saving disc 70 surrounding one side of the burner can be replaced with an energy-saving cover 80, and the energy-saving cover 80 is also provided with pot foot plate through holes for the pot foot plate 60 to pass through.

[0470] Specifically, in this embodiment, the energy-saving cover 80 includes an energy-saving cover 801 and an energy-saving cover tray 802, wherein;

[0471] The energy-saving cover 801 has a flat ring and is placed on the outer edge of the large-fire burner cover 12 or the outer edge of the large-fire burner base 13. The overall height of the energy-saving cover 801 is lower than the flame outlet position of the large-fire flame hole channel 15. The energy-saving cover 801 has a pot foot plate through-hole, and the pot foot plate 60 passes through the pot foot plate through-hole and is inserted into the pot foot plate slot 131 on the large-fire burner base 13.

[0472] The energy-saving cover tray 802 is welded and fixed to the energy-saving cover 801, forming a heat-insulating cavity 81. The energy-saving cover tray 802 also has corresponding through holes for the pot foot pieces 60 to pass through. The energy-saving cover tray 802 is fixed to the high-fire burner base 13 by screws 76, so that the energy-saving cover 80 is fixed to the high-fire burner base 13 and cannot be easily removed. The energy-saving cover 80 configured as described above can reduce the downward conduction and diffusion of heat during burner use, while reducing excess secondary air and improving the thermal efficiency of the burner.

[0473] Through experimental verification, the burner with an energy-saving cover in this embodiment of the application can achieve a heat load of 5.2kW, a CO concentration in dry flue gas of ≤0.0273%, and a thermal efficiency of 70.5%, which further improves the various performance indicators of the burner.

[0474] It should be noted that the energy-saving cover 801 in this embodiment can also be a flat surface on the outer slope of the large-fire burner base 13, that is, the energy-saving cover itself is part of the large-fire burner base 13.

[0475] In summary, by adding corresponding gas distribution modules {annular gas distribution component 30, C-shaped gas distribution component 40 and flame gas distribution plate 50} and / or energy-saving modules {energy-saving cover 70 or energy-saving cover 80} to the burner in this embodiment, the various performance indicators of the burner can be effectively improved.

Therefore, detailed improvements to the specific components themselves are not elaborated upon. Those skilled in the art will understand that Embodiment 8 may employ improvements from Embodiments 1-7 or combine different improvements.

[0477] It should also be noted that the burner improvements provided in this application are preferably used for stove burners. The energy-saving improvements in Examples 6 and 7 can be applied to different types of stove burners, while the gas distribution improvements in Examples 1-5 are more suitable for ring burners with annular flame channels and / or annular flame holes.
