Description

Technical Field

[0001] This invention relates to a high-efficiency burner. Background Technology

[0002] Currently, the mainstream gas stove burners on the market are mainly divided into two categories: single-ejector burners and double-ejector burners. Single-ejector burners supply gas to the center flame and the outer ring flame simultaneously through a single ejector tube. They have inherent defects such as mutual interference between the gas flow of the center flame and the outer ring flame, poor flame adjustment accuracy, uneven circumferential flame distribution of the outer ring flame, and insufficient mixing of gas and air. They have been gradually phased out of the market.

[0003] While traditional dual-ejector burners have improved some of the problems of single-ejector burners to a certain extent, they still have the following issues: simple gas distribution structure, low gas distribution accuracy, most of them use straight baffles or have no dedicated gas distribution structure, the gas is directly impacted by the gas distribution plate after being ejected from the ejector, generating eddies and pressure loss, the gas distribution ratio between the center flame and the outer ring flame is unstable, and the problem of excessively strong center flame and insufficient local firepower in the outer ring flame is easy to occur; a single air inlet cannot meet the primary air demand under high load and high firepower conditions, resulting in a low primary air coefficient, incomplete combustion, large heat loss, and easy carbon deposits clogging the burner holes. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly efficient burner that fully mixes gas and air, significantly improves combustion efficiency, provides precise gas distribution, and delivers uniform and consistent firepower.

[0006] In this technical solution, the burner head body includes an upper half shell and a lower half shell; the upper half shell is installed on the upper part of the lower half shell, and the upper and lower half shells are provided with corresponding half grooves to form two ejector tubes, two outer ring flame flow channels and a central flame flow channel.

Detailed Implementation

[0013] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0014] like Figures 1 to 10 The image shows a high-efficiency burner, comprising: The burner head body includes a gas inlet 45, an air inlet 44, a mixing chamber 51, two ejector tubes 7, two outer ring flame flow channels 6, a central flame flow channel 8, two arc-shaped gas distribution baffles 9, a central flame outlet 41, and two outer ring flame outlets 42. The two ejector tubes 7 and the two outer ring flame flow channels 6 are symmetrically distributed in the burner head body. The outlets of the two ejector tubes 7 are respectively connected to the inlets of the corresponding outer ring flame flow channels 6 and the inlets of the central flame flow channels 8. The two arc-shaped gas distribution baffles 9 are located at the outlets of the corresponding ejector tubes 7. At the connection point where the air inlet of the outer ring gas flow channel 6 and the air inlet of the central gas flow channel 8 are connected, the arc-shaped gas distribution plate 9 bends toward the outer ring gas flow channel 6, the air outlets of the two outer ring gas flow channels 6 are connected to the corresponding outer ring gas outlet 42, the central gas flow channel 8 is connected to the central gas outlet 41, the air outlets of the gas inlet 45 and the air inlet 44 are respectively connected to the first air inlet of the mixing chamber 51, the mixing chamber 51 is also provided with a second air inlet 511 connected to the outside air, and the air outlet of the mixing chamber 51 is connected to the air inlet of the two ejector tubes 7. Upper flame distribution structure 3; the upper flame distribution structure 3 covers the upper part of the furnace head body and communicates with the central flame outlet 41 and the two outer ring flame outlets 42. A central flame cap 1 and an outer ring flame cap 2; the central flame cap 1 is mounted on the upper flame distributor structure 3 and located above the central flame outlet 41, and the outer ring flame cap 1 is mounted on the upper flame distributor structure 3 and located above the outer ring flame outlet 42; and Ignition assembly; the ignition assembly is installed on the burner body to ignite the gas.

[0015] During operation, two symmetrically distributed ejector tubes 7 and two outer ring fire flow channels 6 are used to ensure uniform distribution of pressure and flow in the outer ring fire, resulting in even heating of the pot bottom and good cooking effect. At the connection between the gas outlet of the ejector tube 7 and the outer ring fire flow channel 6 and the central fire flow channel 8, an arc-shaped gas distribution baffle 9 that bends towards the outer ring fire flow channel is set. The fluid dynamics wall effect is used to smoothly guide the mixed gas to split, avoiding airflow impact, eddies and pressure loss caused by straight baffles. This ensures that the central fire is stable and small while the outer ring fire receives a sufficient gas supply.

[0016] In this embodiment, the burner head body includes an upper half-shell 4 and a lower half-shell 5. The upper half-shell 4 is installed on the upper part of the lower half-shell 5. The upper half-shell 4 and the lower half-shell 5 are provided with corresponding semi-grooves to form two ejector tubes 7, two outer ring flame flow channels 6, and a central flame flow channel 8. The upper half-shell 4 and the lower half-shell 5 are also provided with corresponding upper and lower partitions to form an arc-shaped gas distribution partition 9. The central flame outlet 41 and the two outer ring flame outlets 42 are located on the upper half-shell 4. The process is convenient.

[0017] In this embodiment, the upper flame distributor structure 3 includes a central flame distributor 31 and an outer ring flame distributor 32. The central flame distributor 31 is located above the central flame outlet 41, and the outer ring flame distributor 32 is located above the two outer ring flame outlets 42.

[0018] In this embodiment, the ignition assembly includes an ignition needle 10 and a thermocouple 11. The ignition needle 10 and thermocouple 11 are respectively installed on the burner body, with the ignition end of the ignition needle 10 located next to the central flame outlet 41. In use, the ignition needle 10 generates a high-voltage electric spark to ignite the gas, and the thermocouple 11 senses the flame temperature; if the flame extinguishes, the gas valve is closed. This technical solution also includes a mixing channel 46, the inlet of which is connected to the outside air, and the outlet of which is connected to both the air inlet 44 and the gas inlet 45. In use, the mixing channel 46 acts as a common air pressure stabilizing channel, effectively buffering the impact of external airflow fluctuations on the combustion system, ensuring that the air pressure entering the gas inlet and air inlet remains stable and consistent, and guaranteeing that the air-fuel ratio is always within the optimal combustion range.

[0019] In this embodiment, the arc radius of the arc-shaped air distribution baffle 9 is 7mm, 9mm, or 11mm, and the arc area is 127mm². 2 Or 131mm 2 Or 135mm2 .
