A flange hole burner

Abstract

The utility model discloses a flanged hole burner, comprising a burner body, wherein at least two fire holes are arranged on the burner body, and the burner body is provided with flanges outwardly around the fire holes to form flanged holes. The height A of the flanged hole is greater than the wall thickness L of the burner body, and the height of the flanged hole increases the wall thickness in disguise. When an ordinary burner is in use, the flame will directly contact the burner surface through the fire hole, causing the burner surface temperature to rise to form a high-temperature zone. The design of the flanged hole will cause the flame to move outward, and it is not easy to form a high-temperature zone on the burner surface. The diameter B of the fire hole located on the inner wall of the burner body is greater than the diameter C of the fire hole located on the outer wall of the burner body. The fire holes are arranged in two rows and are symmetrically arranged at 180 degrees. The utility model still keeps the fire holes opened on both sides of the burner body by adding the design of the flanged hole. Since the flanged hole has a height, the flame moves outward as a whole away from the burner surface during combustion, and it is not easy for the burner to form a high-temperature zone.

Description

Technical Field

[0001] The utility model relates to the field of burners, and specifically designs a flanging hole burner. Background Art

[0002] The burners of the common barbecue grills on the market use gas to flow directly from the gas source through the combustion holes and burn. This type of burner not only has low combustion efficiency and unstable combustion flames, but is also prone to produce toxic substances. In addition, due to cost constraints, the gas grill burners on the market are generally made of stainless steel pipes. However, the existing ordinary stainless steel burners have two obvious defects in actual use: 1. Since the wall thickness of the stainless steel pipe is generally less than 1mm, the burner is easily affected by high temperature and barbecue sauce during the actual barbecue process, which will cause corrosion and damage to the stainless steel burner, greatly reducing the service life of the gas grill. 2. The original stainless steel burner was designed to open two rows of fire holes on both sides of the burner, but this will cause the flame to completely wrap the upper half of the burner, forming a large area of ​​high temperature area. The subsequent design was changed to a 90° opening method for the two rows of fire holes, but there will also be a defect of poor temperature uniformity, which will have a great impact on the temperature uniformity performance of the entire gas grill. Therefore, it is very important to obtain a flanged hole burner that overcomes the above defects. Utility Model Content

[0004] As a preferred embodiment of the above, the height A of the flanged hole is greater than the wall thickness L of the burner body, and the height of the flanged hole increases the wall thickness in disguise.

[0005] Through the above technical solution, when an ordinary burner is in use, the flame will directly contact the burner surface through the fire hole, causing the burner surface temperature to rise and form a high-temperature zone. The design of the flange hole in this technical solution will cause the flame to move outward, making it difficult to form a high-temperature zone on the burner surface.

[0006] As a preferred embodiment of the above, the diameter B of the fire hole located on the inner wall of the burner body is larger than the diameter C of the fire hole located on the outer wall of the burner body.

[0007] Preferably, the inner wall of the fire hole is an arc surface, and the two ends of the arc surface are respectively connected to the inner wall of the flange and the inner wall of the burner body, so that the fire hole forms an air inlet with an outer port diameter smaller than the inner port diameter.

[0008] The diameter B is larger than the diameter C, and the arc-shaped air inlet can greatly optimize the outflow resistance of the gas, making the combustion condition of the burner body more stable and uniform.

[0009] The inner wall of the flange is connected to the outer wall of the burner body through an arc surface.

[0010] The number of the combustion zones is two, and the two combustion zones are respectively arranged on both sides of the burner body. There are multiple fire holes in each combustion zone, and the multiple fire holes are arranged along the length direction of the burner body. The multiple fire holes in each combustion zone are all located on the axis of the length direction of the burner body. The two combustion zones are relatively distributed so that the fire holes in the two combustion zones are symmetrically arranged at 180 degrees.

[0011] Through the above technical solution, the utility model increases the flange hole design and still keeps the fire holes on both sides of the burner body. Since the flange holes have a height, the flame moves outward as a whole away from the burner surface during combustion, making it difficult for the burner to form a high temperature zone.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure, and the design of the flanged hole can increase the wall thickness of the fire hole and reduce the high-temperature area on the burner body to extend the service life, and good temperature uniformity performance is obtained by opening holes on both sides of the burner.

[0019] As a preferred embodiment of the above, the height A of the flange hole 4 is greater than the wall thickness L of the burner body 1, and the height of the flange hole 4 increases the wall thickness in disguise.

[0020] The above-mentioned wall thickness L is in the range of 1-2 mm.

[0021] The traditional wall thickness is less than 1mm. During the actual barbecue process, the burner is very susceptible to the influence of high temperature and barbecue sauce, which will cause corrosion and damage to the stainless steel burner, greatly reducing the service life of the gas barbecue oven. The wall thickness of the utility model is increased, which can overcome the above defects, is not easy to damage the stainless steel burner, and increases the service life of the burner.

[0022] Through the above technical solution, when an ordinary burner is in use, the flame will directly contact the burner surface through the fire hole 2, causing the burner surface temperature to rise to form a high-temperature zone. The design of the flange hole 4 in the present technical solution will cause the flame to move outward, making it difficult to form a high-temperature zone on the burner surface.

[0023] The flange 3 and the burner body 1 are integrally formed, which is convenient for mass production, and the integrally formed burner body has a longer service life.

[0024] As a preferred embodiment of the above, the diameter B of the fire hole 2 located on the inner wall of the burner body 1 is larger than the diameter C of the fire hole 2 located on the outer wall of the burner body 1 .

[0025] The inner wall of the fire hole 2 is an arc surface 5, and the two ends of the arc surface 5 are respectively connected to the inner wall of the flange 3 and the inner wall of the burner body 1, so that the fire hole 2 forms an air inlet with an outer port diameter smaller than the inner port diameter.

[0026] The diameter B is larger than the diameter C, and the arc-shaped air inlet can greatly optimize the outflow resistance of the gas, making the combustion condition of the burner body 1 more stable and uniform.

[0027] The inner wall of the flange 3 is connected to the outer wall of the burner body 1 via a curved surface 6 to make the air flow smoother.
