Description

Technical Field

[0001] This utility model relates to the field of burners, and in particular to a hot water boiler burner. Background Technology

[0002] Traditional hot water heater burners are mostly floor-standing models, usually fixed below the hot water heater, and heat the hot water heater by burning gas.

[0003] Traditional hot water boiler burners have two major drawbacks: the flame is concentrated and columnar, and uneven heat radiation leads to localized overheating; during combustion, condensate produced on the outer wall of the hot water boiler accumulates on the burner head under the influence of gravity, and the condensate seeps into the nozzles, inducing micro-explosions or even flameout. Utility Model Content

[0004] The purpose of this invention is to provide a hot water boiler burner to solve the above-mentioned problems.

[0005] According to one aspect of this utility model, a hot water boiler burner is provided, comprising: a gas pipe and a burner head, the burner head including a lower baffle and an upper baffle, the lower baffle having a gas supply hole in the middle for communicating with the gas pipe, the top surface of the lower baffle having a plurality of first protrusions arranged circumferentially around the gas supply hole, a first gas outlet groove being formed between adjacent first protrusions, the bottom surface of the upper baffle having a plurality of second protrusions corresponding to the first protrusions, a second gas outlet groove being formed between adjacent second protrusions, the first protrusions and the second protrusions being welded together, the first gas outlet groove and the second gas outlet groove being combined to form a gas outlet channel; the edge of the lower baffle having an annular water groove, the inner side of the annular water groove having a drain hole corresponding to the first gas outlet groove.

[0006] In some embodiments, both the lower baffle and the upper baffle are circular structures; the diameter of the lower baffle is larger than the diameter of the upper baffle.

[0007] In some embodiments, the first air outlet groove is radially oriented toward the air supply hole; the second air outlet groove is radially oriented toward the center of the upper baffle.

[0008] In some embodiments, the cross-sections of both the first and second air outlet grooves are arc-shaped grooves.

[0009] In some embodiments, the edge of the upper baffle extends downward to provide a water guide, the end of which hangs directly above the water tank.

[0010] In some embodiments, multiple fixed supports are welded to the outside of the gas pipe.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] During combustion, the flame forms a lotus-shaped flame outside the exhaust channel, increasing the contact area between the flame and the heated surface and improving thermal efficiency. After the condensate falls into the burner head, the combination of the drain hole and the annular water groove completely eliminates the accumulation of condensate and avoids the risk of flameout.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figures 1 to 5 This application provides a hot water boiler burner, including: a gas pipe 1 and a burner head 2. The burner head 2 includes a lower baffle 3 and an upper baffle 4. The lower baffle 3 has a gas supply hole 5 in the middle for communicating with the gas pipe 1. The top surface of the lower baffle 3 has a plurality of first protrusions 6 arranged circumferentially around the gas supply hole 5. A first gas outlet groove 7 is formed between adjacent first protrusions 6. The bottom surface of the upper baffle 4 has a plurality of second protrusions 8 corresponding to the first protrusions 6. A second gas outlet groove 9 is formed between adjacent second protrusions 8. The first protrusions 6 and the second protrusions 8 are welded together. The first gas outlet groove 7 and the second gas outlet groove 9 are combined to form a gas outlet channel 10. The edge of the lower baffle 3 is provided with an annular water groove 11. The inner side of the annular water groove 11 is provided with a drain hole 12 corresponding to the first gas outlet groove 7.

[0020] In some embodiments, both the lower baffle 3 and the upper baffle 4 are circular structures; the diameter of the lower baffle 3 is larger than the diameter of the upper baffle 4.

[0021] In some embodiments, the first vent groove 7 is radially oriented toward the air supply hole 5; the second vent groove 9 is radially oriented toward the center of the upper baffle 4.

[0022] In some embodiments, the cross-sections of the first air outlet groove 7 and the second air outlet groove 9 are both arc-shaped grooves to increase the air guiding area.

[0023] In some embodiments, the edge of the upper baffle 4 extends downward and is provided with a water guide 13, the end of which hangs over the water tank.

[0024] In some embodiments, a plurality of fixed supports 14 are welded to the outside of the gas pipe 1.

[0025] When in use, the gas is delivered through the gas pipe 1 to the cavity between the upper baffle 4 and the lower baffle 3 and is evenly discharged outward through the gas outlet channel 10. When burning, it presents a lotus-shaped flame. When the condensate falls into the top of the upper baffle 4, it can be discharged along the water guide 13 to the annular water tank 11 below. When the water in the annular water tank 11 accumulates to a certain amount, it is discharged along the drain hole 12.

[0026] During combustion, the flame forms a lotus-shaped flame outside the exhaust channel 10, which increases the contact area between the flame and the heated surface and improves thermal efficiency. After the condensate falls into the burner head 2, the cooperation between the drain hole 12 and the annular water tank 11 completely eliminates the accumulation of condensate and avoids the risk of flameout.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
