The exhausted harmful gas. Further, the air intake pipe 11, the mixing plate 2, and the mating structure of the dispensing plate 4 are simple, not only ensures that the premixing of air and the gas is better, but also the cost of the premixing device is low.
[0035] Further, such as figure 2 As shown, the mixture plate 2 forms a first premixing region 51 between the dispensing plate 4, and the dispensing plate 4 forms a second premixing region 52 between the mixed air outlet 71, and the mixture distribution hole 41 functions. District 51 and the second premixing region 52.
[0036] It should be noted that the term "first", "second" is used only for the purpose of describing purposes, and cannot be understood as an indication or implies relative importance or implicitting the number of techniques indicated. Thereby, the features of "first", "second" may be defined, and one or more of this feature may be further included. In the description of the invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0037] In a specific embodiment, when air is entered into the first premix region 51, since the space is suddenly expanded, the flow rate of air and gas is rapidly reduced, and the air can be mixed with the gas, which facilitates improving the degree of mixing of air and gas. Subsequently, the gas mixture enters the second premixing region 52 from the mixture distribution hole 41, and the distribution plate 4 is uniformly dissipated, and when the air and gas can be performed again when it enters the second premixing region 52. Mixing to ensure uniform mixing of air and gas, and, the mixed gas mixture can be uniformly flooded at the mixed air outlet 71.
[0038] Further, the mixture dispensing hole 41 is configured with the air outlet of the premixing tube 21, which can increase the path of the mixed gas in the first premixing region 51, thereby preventing gas mixing air from passing through the wind pressure of the exhaust. The mixture dispensing hole 41 causes a poor mixture of air and gas.
[0039] Further, such as Figure 1 - Figure 2 As shown, a swirling blade 6 is provided in the premixing tube 21, and a third premixing region 53 is formed between the outlet end of the air intake pipe 11 and the swirl blade 6.
[0040] The swirl blades 6 can be rotated under the action, and therefore, a swirling blade 6 is provided in the premixing tube 21, and it is possible to further improve the effect of gas mixing with the air. Further, there is a gap between the outlet end of the air intake pipe 11 and the swirl blades 6 to form a third premixing region 53, which provides a space to the air with the air.
[0041] Further, the air intake pipe 11 is a plurality of swirl blades 6, and the premixing tube 21 corresponds to the air intake pipe 11. Therefore, when air enters into the cavity, the air is uniformly flowing into the respective air intake pipes 11, and the gas flows out from each corresponding gas intake passage 3, thereby not only reduce the flow rate of intake air, not only. It is guaranteed that the air resistance is small, and the mixing effect of air and gas can also be improved.
[0042] Preferably, the plurality of air intake pipes 11 are uniformly arranged, thereby facilitating ensuring uniform air volume of the respective air intake pipes 11, which further benefits the mixing effect of gas and air.
[0043] In the specific embodiment, if figure 2 As shown, the gas and air will perform initial contact, mix, and, under the action of air and gas flow inertia, and therefore, when air and gas are passed through the flow inertia of air and gas. When the swirling blade 6, the flow blade 6 will stir the gas to air, so that the gas can be mixed into the inside of the air, and the mixing effect of gas and air can be further improved, and the gas and air will enter the first In the premix region 51, in the second premixing region 52, the gas and air are in contact with the second premixing region 52 again, and to ensure that the gas is mixed with air.
[0044] Further, such as Figure 1 - Figure 2 As shown, the premixing device can include: the mixture fixing seat 7 and the intake base 1, the mixture fixing seat 7 is located above the intake base 1, and the mixture fixing seat 7 is enclosed in a cavity, air into the air. The air pipe 11 is located on the intake base 1, and the gas inlet 12 is formed on the intake base 1, and the air intake pipe 11 is sturdy, and the mixture air outlet 71 is located at the top of the mixed retaining seat 7, that is, mixed air The fixing seat 7 has a hollow cavity having a port on both sides, and the bottom surface of the mixture fixing seat 7 is fitted to the intake base 1 to enclose the cavity, the intake pipe is located on the intake base 1, and the gas inlet 12 is formed. On the intake base 1, the top surface of the mixed fixing seat 7 forms a mixed air outlet 71.
[0045] Further, the mixing plate 2 is located in the mixed retaining seat 7, and the mixing plate 2 is located above the intake base 1, thereby ensuring that the gas can be mixed with the air in the third premixing region 53.
[0046] Specifically, the mixing wall of the adjacent two premix tubes 21 is aligned with the base connection wall of the adjacent two air intake pipe 11, to form a hollow portion 8 between the connecting wall connecting the wall connecting wall and the base connection wall. The gas inlet 12 is in communication with the hollow portion 8 through the gas intake passage 3.
[0047] Therefore, when the gas can be stored, the gas can be temporarily stored in the hollow portion 8, and when the gas in the hollow portion 8 is full, the gas that is continuously flowing into the hollow portion 8 can squeeze the gas stored in the hollow portion 8. Each gas intake passage 3 thus enables all gas intake passages 3 to flow out, which in turn ensures that the effect of air and gas mixing is better.
[0048] Further, the air intake pipe 11 is a linholic tube, and the inlet segment of the air intake pipe 11 is facing the outside, and the air inlet 111 of the air intake is formed, and the diffusion section of the air intake pipe 11 is toward the top surface of the mixed retaining seat 7, therefore, The air intake pipe 11 is a Wenqi tube. When the air passes through the air intake pipe 11, the flow rate of the air can be improved, so that the air of the air can increase the impact force of the gas, and further improve the mixing effect of air and gas.

The heat released by the combustion can maintain the lifting temperature required for the catalytic burner 9 itself, and on the other hand, heat exchanger is heated, and the flame is more soft and smooth, and the noise is low, thereby ensuring the gas water heater at work. Friendly is more friendly in the external environment, thereby ensuring the use of gas water heaters more environmentally friendly and safe and comfortable.
[0055] In a specific embodiment, when the gas water heater starts working, the air enters the air intake pipe 11 from the plurality of air inlet 111, while the gas begins to supply, the gas flows into each gas intake passage 3, air and gas in the third The premixing region 53 is initially mixed, and the gas is stirred with air under the rotation of the swirl blades 6, and then all gas and air are aggregated in the second premixing region 52 to carry out another mix, and the distribution plate 4 pair After the gas mixing is dispersed, the final mixing is performed at the first premixing region 51, and finally the mixed gas mixture is uniformly discharged from the mixed air outlet 71, and the preheating burner 9 is ignited after mixing gas mixing, while The heat exchanger is heated with the catalytic burner 9. When the catalytic burner 9 reaches the operating temperature, the preheating burner 9 stops working, the catalytic burner 9 continues to heat the heat exchanger, thereby the heat exchanger Heating is performed to ensure that the gas water heater has continuously hot water to complete the heating process of the gas water heater.
[0056] It should be noted that the premixing device can not only be used in the gas water heater, but also mixed with air, but also in other combustion heat exchange devices, for example, in nitrogen vehicles, the premixing device can be mixed with air. .
