Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a three-ring fire burner. Background Art

[0002] Existing household gas stoves typically feature a double-ring burner head, with an outer ring and a center ring. The maximum power of such burners is typically no more than 4.2 kW. The corresponding gas control device for these double-ring burners is a double-ring valve body. As cooking becomes more diverse, the need for more varied burner head temperatures has spurred the development of triple-ring burners, which can reach power levels exceeding 5.2 kW. These burners typically utilize a single triple-ring gas valve. However, existing triple-ring gas valves have a narrow power adjustment range and cannot meet diverse user demands.

DETAILED DESCRIPTION

[0018] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0019] Combine Figures 1 to 3 A three-ring fire burner shown includes a burner body 2 and a double-valve control module. An outer fire ring 3, an inner fire ring 4 and a central fire ring 5 are installed on the burner body 2. The double-valve control module is connected to the outer fire ring 3, the inner fire ring 4 and the central fire ring 5 respectively, so that the central fire ring 5 can be ignited and burned simultaneously with the outer fire ring 3 or the inner fire ring 4; this embodiment uses a double-valve control module to connect the outer fire ring 3, the inner fire ring 4 and the central fire ring 5, so that the central fire ring 5 forms a permanent ignition state, so that the central fire ring 5 can be coordinated according to the use of the outer fire ring 3 or the inner fire ring 4 to meet the use requirements of power below 5.2KW. When high power is required, the outer fire ring 3 and the inner fire ring 4 can be ignited simultaneously through the double-valve control module. Since the central fire ring 5 is in the permanent ignition state, the outer fire ring 3, the inner fire ring 4 and the central fire ring 5 can be used simultaneously, thereby achieving a use requirement of more than 5.2KW. The power usage is higher than that of the traditional three-ring burner to meet various firepower requirements.

[0020] In this embodiment, the outer fire ring 3 is provided with a first inclined surface 19 on its upper surface, and the inner fire ring 4 is provided with a second inclined surface 20 on its upper surface. Both the first inclined surface 19 and the second inclined surface 20 are inclined toward the center fire ring 5. A first air outlet 21 is provided on the first inclined surface 19 and the second inclined surface 20. The center fire ring 5 is provided with a third inclined surface 22 on its upper surface. The third inclined surface 22 is inclined toward the inner fire ring 4. A second air outlet 23 is provided on the third inclined surface 22. When the premixed gas is burned, the first air outlet 21 on the outer fire ring 3 and the inner fire ring 4 sprays toward the center and upward, making the flame more concentrated under the pot bottom and reducing the phenomenon of heat rapidly diffusing outward. The second air outlet 23 on the center fire ring 5 can spray and burn outward, so that the flame on the center fire ring 5 cooperates with the outer fire ring 3 or the inner fire ring 4, so that the heat is more evenly distributed under the pot bottom and the heat utilization rate is higher.

[0021] It is worth noting that the upper end surface of the third inclined surface 22 of this embodiment is provided with a heat-insulating ring 24. A temperature sensor 6 is inserted into the heat-insulating ring 24 to implement a dry-burn prevention function, and the heat-insulating ring 24 can surround the outside of the temperature sensor 6 to prevent the temperature sensor 6 from being directly burned and causing misjudgment.

[0022] The burner body 2 of this embodiment is respectively provided with an outer fire gas groove 16, an inner fire gas groove 17 and a central fire gas groove 18, the outer fire ring 3 is covered on the outer fire gas groove 16, the inner fire ring 4 is covered on the inner fire gas groove 17, and the central fire ring 5 is covered on the central fire gas groove 18, and the lower end of the burner body 2 is respectively provided with a first ejection tube 25, a second ejection tube 26 and a third ejection tube 27, the outer fire gas groove 16 is connected to the first ejection tube 25, the inner fire gas groove 17 is connected to the second ejection tube 26, and the central fire gas groove 18 is connected to the third ejection tube 27, and the first ejection tube 25, the second ejection tube 26 and the third ejection tube 27 are parallel to each other; the outer fire gas groove 16, the inner fire gas groove 17 and the central fire gas groove 18 can be used to eject premixed gas through their respective ejection tubes.

[0023] The burner body 2 of this embodiment is mounted on the base 1, and the first nozzle seat 7, the second nozzle seat 8 and the third nozzle seat 9 are respectively provided on one side of the base 1. The output end of the first nozzle seat 7 is connected to the first ejector tube 25, the output end of the second nozzle seat 8 is connected to the second ejector tube 26, and the output end of the third nozzle seat 9 is connected to the third ejector tube 27. The input ends of the first nozzle seat 7, the second nozzle seat 8 and the third nozzle seat 9 are all connected to the dual-valve control module, so that the outer fire ring 3, the inner fire ring 4 and the center fire ring 5 can be coordinated and controlled by the dual-valve control module. Specifically, the dual-valve control module includes a first control valve 10 and a second control valve 11. The first control valve 10 is connected to a first air pipe 12 and a second air pipe 13. The first air pipe 12 is connected to the input end of the first nozzle holder 7, and the second air pipe 13 is connected to the input end of the third nozzle holder 9. The second control valve 11 is connected to a third air pipe 14 and a fourth air pipe 15. The third air pipe 14 is connected to the input end of the second nozzle holder 8, and the fourth air pipe 15 is connected to the input end of the third nozzle holder 9. The outer fire ring 3 and the center fire ring 5 are independently controlled by the first control valve 10, while the inner fire ring 4 and the center fire ring 5 can be controlled by the second control valve 11. This allows the center fire ring 5 to be constantly ignited during use, thereby meeting the power requirements for more cooking.

[0024] It is worth noting that the burner body 2 of this embodiment is provided with a support leg 28 at the lower end, which is mounted on the base 1 through the support leg 28, so that a gap is formed between the burner body 2 and the base 1 to facilitate the entry of air.

[0025] It's worth noting that a flameout protection pin is also mounted on the base 1 of this embodiment. This pin is positioned between the inner flame ring 4 and the center flame ring 5. Both the first control valve 10 and the second control valve 11 are connected to the flameout protection pin via a signal line. Since the center flame ring 5 remains ignited during use, the flameout protection pin can be used to detect whether the center flame ring 5 has accidentally gone out, facilitating activation of the flameout protection switch.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
