Technical Field

[0001] The invention belongs to the technical field of burners, and in particular relates to a burner with a double-layer pot rack. Background Art

[0002] As a convenient and fast cooking appliance, gas stoves have become popular in the kitchens of thousands of households. The burners of gas stoves can use gas fuels such as liquefied petroleum gas, artificial coal gas, and natural gas for direct fire heating, thereby quickly heating cooking pots. As for the existing burner components, they generally include a burner (including a burner head, a gas distribution plate and a fire cover, etc.), a control valve, an igniter, an ejector tube, etc. Its working process is that the gas supplied by an external gas pipe or a gas tank is transported to the burner through the control valve and the ejector tube, and the igniter ignites the gas at the burner to generate heat. The existing outer fire cover is provided with one or more fire discharge holes on the outer wall, while the inner wall of the outer fire cover is not provided with fire discharge holes. The inner side only relies on the fire discharge holes on the inner fire cover on the burner to form an inner ring flame, and the outer wall of the outer fire cover is generally a circular surface. The number of fire discharge holes is small, the fire discharge area is small, the combustion efficiency of the burner is average, and the combustion is insufficient. Existing patent documents disclose a utility model patent for an outer ring fire cover and burner that is easy to ignite (Announcement No.: CN217540742U). Its technical solution records that a row of fire holes are set on the outer wall of the outer fire cover, but no fire holes are set on the inner wall of the outer fire cover. The overall combustion efficiency is average, the combustion is insufficient, and the above-mentioned technical problems also exist. Summary of the Invention

[0003] The purpose of the present invention is to provide a technical solution for a burner with a double-layer pot rack in response to the shortcomings of the existing technology. The structural design is ingenious and reasonable, and the practicability is strong. The outer ring fire cover adopts the cooperation of the inner ring fire hole and the outer ring fire hole to form two gas airflows, enhance the mixing degree of gas and air, and improve the combustion efficiency of the burner. At the same time, two inner and outer ring flames are formed on the outer ring fire cover to improve the thermal efficiency of the burner.

DETAILED DESCRIPTION

[0040] like Figures 1 to 14 As shown, a burner with a double-layer pot rack of the present invention includes a burner 1, a base 2, a fire dividing cover and a pot rack 25. The base 2 is arranged on the burner 1, and the fire dividing cover is arranged on the base 2. The fire dividing cover includes an outer ring fire cover 3 and an inner ring fire cover 4; the outer ring fire cover 3 includes a top wall 5, an inner side wall 7 and an outer side wall 6, and an inner inclined surface 8 is connected between the top wall 5 and the inner side wall 7. A groove group 19 is provided on the inner inclined surface 8, and the groove group 19 includes at least one groove 12, and an inner ring fire hole 10 is provided in the groove 13; an outer inclined surface 11 is connected between the top wall 5 and the outer side wall 6, and a groove group 2 12 is provided on the outer inclined surface 11. The groove group 2 12 includes at least one groove 24, and an outer ring fire hole is provided in the groove 24.

[0041] The inner ring fire outlet hole 10 is coordinated with the outer ring fire outlet hole to form two gas airflows, thereby enhancing the mixing degree of gas and air and improving the combustion efficiency of the burner. At the same time, two inner and outer ring flames are formed on the outer ring fire cover 3 to improve the thermal efficiency of the burner. The inner ring fire outlet hole 10 is arranged in groove one 23, and the outer ring fire outlet hole is arranged in groove two 24. The design of the groove can increase the flame area at the fire outlet hole, making it less likely for flame separation to occur, and the flame formation is more stable, which effectively improves the combustion thermal efficiency and improves energy efficiency.

[0042] At least two groove groups 9 are provided, with several groove groups 9 distributed circumferentially along the inner bevel 8. The groove groups 9 are preferably evenly distributed circumferentially on the inner bevel 8, ensuring uniformity in the layout of the inner ring of fire holes 10, thereby forming a stable inner ring flame and achieving uniform heating. At least two groove groups 12 are provided, with several groove groups 12 distributed circumferentially along the outer bevel 11. The groove groups 12 are preferably evenly distributed circumferentially on the outer bevel 11, ensuring uniformity in the layout of the outer ring of fire holes, thereby forming a stable outer ring flame and achieving uniform heating. A burn-proof zone 22 is formed between adjacent groove groups 12, allowing the outer flame to avoid the pot support 25, thereby preventing burns on the pot claws of the pot support 25, reducing heat loss, and lowering the carbon monoxide content in the combustion products.

[0043] The outer wall 6, the outer bevel 11, the top wall 5, the inner bevel 8 and the inner side wall 7 are connected in sequence to form a mixing chamber 14 at the bottom of the outer ring fire cover 3. The inner ring fire hole 10 and the outer ring fire hole are connected to the mixing chamber 14. A reinforcing protrusion 15 is provided in the mixing chamber 14. The inner ring fire hole 10 passes through the reinforcing protrusion 15. The gas and air are mixed in the mixing chamber 14 and buffered in the mixing chamber 14. The inner ring fire hole 10 and the outer ring fire hole are connected to the mixing chamber 14 so that the mixed gas in the mixing chamber 14 can enter the inner ring fire hole 10 and the outer ring fire hole. The design of the reinforcing protrusion 15 can enhance the overall structural strength of the outer ring fire cover 3, improve the quality of the outer ring fire cover 3, and extend the service life of the outer ring fire cover 3. The inner ring fire hole 10 just passes through the reinforcing protrusion 15, so that the outer ring fire cover 3 is not easy to break when the inner ring fire hole 10 is processed, thereby facilitating the processing and manufacturing of the outer ring fire cover 3.

[0044] The reinforcing protrusions 15 are distributed circumferentially along the mixing chamber 14, and a guide groove 16 is formed between two adjacent reinforcing protrusions 15. The reinforcing protrusions 15 are distributed circumferentially in the mixing chamber 14, and the reinforcing protrusions 15 are preferably arranged to be uniformly distributed circumferentially in the mixing chamber 14, thereby improving the structural stability and firmness of the entire outer ring fire cover 3, and guide grooves 16 are formed between adjacent reinforcing protrusions 15. The guide grooves 16 can be used to more conveniently guide the gas to the outer ring fire outlet, thereby improving the combustion efficiency of the outer ring fire cover 3 and also playing a role in stabilizing the fire.

[0045] The inner bevel 8 extends downward from the inner edge of the top wall 5 to the inner side wall 7, and the inner bevel 8 is set downwardly toward the center of the outer ring fire cover 3. The outer bevel 11 extends downwardly from the outer edge of the top wall 5 to the outer side wall 6, and the outer bevel is set downwardly away from the center of the outer ring fire cover 3. The inner bevel 8 and the outer bevel 11 are straight bevels or curved bevels, and the design is simple and reasonable. The inner bevel 8 and the outer bevel 11 can be adjusted to straight bevels or curved bevels according to actual design requirements. The outer bevel 11 adopts a bevel design to guide the secondary air well, reduce the smoke generated at the outer ring fire hole, and improve the combustion efficiency. In the present application, the inner bevel 8 is preferably designed as a curved bevel to ensure the energy gathering effect on the inner side of the outer ring fire cover 3. The inner bevel 8 and the outer bevel 11 are not limited to straight bevels or curved bevels, and can also be a combination of straight lines and curves.

[0046] A fire transfer groove 13 is provided on the outer ring fire cover 3. The fire transfer groove 13 is used to conduct the flame to the outer ring fire hole. The fire transfer groove 13 is provided on the surface of the outer ring fire cover 3, shortening the communication path between the inner ring fire hole 10 and the outer ring fire hole, which is more conducive to the transmission of the inner flame to the outer flame, improves the reliability of flame transmission, and makes the flame transmission effect good, fast and short. The cross-section of the inner ring fire hole 10 and the outer ring fire hole can be circular, polygonal or irregular.

[0047] Fire transfer holes 17 are provided on both sides of the fire transfer groove 13, and the groove 23 adjacent to the fire transfer hole 17 is a blind groove. The groove 23 adjacent to the fire transfer hole 17 is a blind groove design, and the inner ring fire outlet hole 10 is not provided on the groove 23, thereby improving the structural strength of the outer ring fire cover 3 where the fire transfer groove 13 and the fire transfer hole 17 are provided, and extending the service life of the outer ring fire cover 3. The fire transfer holes 17 are provided on both sides of the fire transfer groove 13, and the fire transfer holes 17 are preferably symmetrically provided on both sides of the fire transfer groove 13, so that the gas formed above the end of the fire transfer groove 13 has a steady flow, thereby making the flame combustion more stable and improving the flame quality, and the fire transfer hole 17 is provided close to the inner side wall 7 of the outer ring fire cover 3, so that the fire transfer groove 13 can transfer the flame at the fire transfer hole 17 to the outside of the outer ring fire cover 3, ignite the outer ring fire outlet hole, and make the flame transfer more stable and reliable.

[0048] The outer ring fire hole is tilted on the outer inclined surface 11, and the outer ring fire hole is tilted downward from the outside of the outer ring fire cover 3 to the mixing chamber 14. The design is ingenious and reasonable. This design makes the end of the outer ring fire hole connected to the mixing chamber 14 lower than the flame outlet end of the outer ring fire hole, so that it is roughly the same as the direction of upward transmission of the gas, which is more conducive to the transmission of gas into the outer ring fire hole, making the flame conduction more reliable.

[0049] The outer ring fire holes include outer ring fire hole 18 and outer ring fire hole 2 19. The diameter of outer ring fire hole 18 is larger than the diameter of outer ring fire hole 2 19. Outer ring fire hole 18 and outer ring fire hole 2 19 are distributed up and down in groove 2 24. The design is reasonable. The outer ring fire holes adopt the design of outer ring fire hole 18 and outer ring fire hole 2 19, so that two rows of outer ring fire holes are formed on the outside of the outer ring fire cover 3. At the same time, since the diameter of outer ring fire hole 18 is larger than the diameter of outer ring fire hole 2 19, the upper outer ring fire hole 18 is the main combustion fire hole, and the lower outer ring fire hole 2 19 is the main flame stabilization fire hole, thereby making the outer flame more stable. Outer ring fire hole 18 and outer ring fire hole 2 19 can be distributed symmetrically up and down, or they can be staggered up and down.

[0050] A positioning convex ring is provided at the bottom of the outer ring fire cover 3, and the positioning convex ring includes a positioning convex ring 1 20 and a positioning convex ring 21. The positioning convex ring 1 20 is arranged close to the outer wall 6 of the outer ring fire cover 3, and the positioning convex ring 2 21 is arranged close to the inner wall 7 of the outer ring fire cover 3. The positioning convex ring 1 20 and the positioning convex ring 2 21 can cooperate with the base 2 to facilitate the installation and positioning of the outer ring fire cover 3 on the base 2, and the two positioning convex rings are respectively arranged close to the inner and outer walls 6 of the outer ring fire cover 3, so that the two positioning convex rings are located exactly at the two side edges of the mixing chamber 14, so that the positioning convex ring 1 20 and the positioning convex ring 2 21 can also play a sealing role, effectively preventing the mixed gas in the mixing chamber 14 from overflowing from the connection gap between the outer ring fire cover 3 and the base 2, thereby improving the safety of use.

[0051] The pot rack 25 includes a ring plate 1 26 and a ring plate 2 27. The pot rack 25 adopts a double-layer design of the ring plate 1 26 and the ring plate 2 27. The ring plate 1 26 and the ring plate 2 27 cooperate to form an energy-gathering cavity 40. The energy-gathering cavity 40 is hollow or filled with heat-insulating material. The ring plate 1 26 and the ring plate 2 27 are integrally formed to facilitate the overall processing of the pot rack 25.

[0052] The ring plate 26 includes an inclined surface with a wavy structure, a bottom support ring 28 and a top support ring 29. The top support ring 29 is connected to the bottom support ring 28 through the inclined surface. A downwardly concave water receiving groove 30 is formed between the inclined surface and the bottom support ring 28. Through the design of the above structure, not only the energy gathering effect of the pot rack 25 is improved, but also the soup can be slowed down from falling into the water receiving tray, preventing the soup in the water receiving tray from splashing onto the burner, making it easier to clean.

[0053] The ring disk 27 includes an inclined portion 1 35, an inclined portion 2 36 and a support surface 37. The inclined portion 1 35 is connected to the inclined portion 2 36 through the support surface 37. The inclined portion 1 35 is close to the top support ring 29, and the inclined portion 2 36 is close to the bottom support ring 28, so as to form an energy-gathering cavity 40 of the required size and improve the energy-gathering effect.

[0054] A retaining ring 1 31 is provided on the bottom support ring 28 , and a retaining ring 2 38 is provided on the inclined portion 2 36 . A channel 39 is formed between the retaining ring 1 31 and the retaining ring 2 38 .

[0055] A supporting foot 33 is provided on the ring plate 27, and a supporting portion 34 is provided on the supporting foot 33. The supporting portion 34 is attached to the supporting surface 37. Four pot foot pieces 32 distributed in a ring are provided on the inclined surface to support the bottom of the pot. The pot foot pieces 32 and the supporting foot 33 on the same side are located in the same vertical plane. The structural design is reasonable, which effectively improves the overall supporting strength and structural stability.

[0056] The structural design of the present invention is ingenious and reasonable, with strong practicality. The inner ring fire outlet hole 10 and the outer ring fire outlet hole are combined to form two gas airflows, enhance the mixing degree of gas and air, and improve the combustion efficiency of the burner. At the same time, two inner and outer ring flames are formed on the outer ring fire cover, thereby improving the thermal efficiency of the burner. The inner ring fire outlet hole 10 is arranged in groove 1 23, and the outer ring fire outlet hole is arranged in groove 2 24. The design of the groove can increase the flame area at the fire outlet hole, making it less likely to cause flame separation and making the combustion more complete. At the same time, the pot rack 25 is designed, and the pot rack 25 has a good energy gathering effect and can slow down the soup from falling into the water receiving tray, thereby preventing the soup in the water receiving tray from splashing onto the burner. It is easy to clean and has strong practicality.
