Upper inclination.
The deflector can be 40~50 ° with the angle of horizontal plane.The structure can simultaneously ensure water conservancy diversion with mixing
Effect.
Preferably, the area of the deflector intermediate throughholes is 0.3~0.7 times of the upper end open area of the sleeve.Should
Structure can accelerate on the premise of water conservancy diversion to gaseous mixture, the gaseous mixture diffusion deceleration suddenly again after entering in mixing chamber,
Not only increasing mixture homogeneity, and reduce the flow velocity of gaseous mixture can provide steady flame effect, while the design of deflector increases
The resistance of gas reflux, so as to avoid tempering.
It is preferred that the flame plate is network structure, air permeability is 4000~5500L/minm2, and the flame plate upper surface
Higher than the upper surface of the sleeve；Flame floats on and stabilization, uniform flame is formed on wire side when so burning, and can also
Be effectively prevented from combustion because fire hole it is excessive caused by flame tempering phenomenon；Flame can be again in burning simultaneously
The air in surrounding environment is filled into, the adequacy of burning is further ensured that.
For convenience of the installation of deflector and flame plate, the outer peripheral edge of the flame plate is downwardly extending the first ring-type wall, institute
The outer peripheral edge for stating deflector upwardly extends to form the second ring-type wall, and first wall and second wall are each attached to institute
State on the inwall of sleeve, and the first wall is located between the second wall and the inwall of sleeve.
Compared with prior art, burner for gas water-heater provided by the utility model, can send to injector
Gaseous mixture introduce auxiliary air, increase combustion gas in oxygen mixed volume, while repeatedly being mixed to gaseous mixture, it is ensured that combustion
The abundant burning of gas, improves the efficiency of combustion of combustion gas, so that the generation of NOx is effectively reduced, it is environment-friendly.

Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1 to Figure 3, the burner for gas water-heater includes at least one fire row being connected with injector 1.
The structure of injector 1 can as needed from it is of the prior art any one.
Fire row includes：
Mix room 2, closed structure, its entrance is connected with the outlet of injector 1, it is pre- for what is sent to injector 1
Combustion gas and primary air gaseous mixture after mixed carry out stream and once mix；Multiple outlets are interval with the side wall for mixing room 2
Hole 21.
Sleeve 3, is set in outside mixing room 2, and the side wall of sleeve 3 and the space mixed between room 2 form and mix air cavity 31 again,
Carry out premix and flow for the auxiliary air and mixed once gas to introducing.
Flame plate 4, is arranged in the outlet of sleeve 3, and the outer peripheral edge of flame plate 4 is downwardly extending the first ring-type wall 42, the
One ring-type wall 42 is fixed on the madial wall of sleeve 3；Multiple flame holes 41 are interval with flame plate 4.Flame plate 4 in the present embodiment
It is network structure, is prepared from using heat-resisting metal net, air permeability is 4800L/minm2, to the combustion gas stream via outflow
Further mix, and combustion flame is formed in wire netting surface；And the upper surface of flame plate is higher than the upper end of a little higher than sleeve
Face, so that the air being mixed into again during fuel gas buring in surrounding environment, is further ensured that the adequacy of burning.
Deflector 5, deflector 5 is cyclic structure, and its outer peripheral edge upwardly extends to form the second ring-type wall 51, the second wall
51 are fixed on the madial wall of sleeve 3 by the first wall 42；Deflector 5 is located at and mixes between room 2 and flame plate 4, deflector 5 with
Formation diversion cavity 32 between the top surface of room 2 is mixed, the cavity between deflector 5 and flame plate 4 is formed and connects each flame hole 41
Mix chamber 33；Diversion cavity 32 connects the mixing chamber 33 in each flame hole 41 by the intermediate throughholes of deflector.
In the present embodiment, the side wall of its outer peripheral edge branch sleeve 3, and deflector 5 from outside to inside, bottom-up inclination；
In the present embodiment, deflector 5 is 45 ° with the angle of horizontal plane.
The operation principle of the burner for gas water-heater is described as follows：
The mixed once gas that injector is sent enters to mix interior and flow for the first time and mixes, and from venthole outflow, enters
Mix in air cavity again；Air enters mixed air cavity again from the lower port of sleeve, to air is stepped into again in mixed once gas, is formed
Secondary gaseous mixture.
Secondary gaseous mixture enters mixing chamber under the guide functions of deflector, during via diversion cavity；Secondary gaseous mixture enters
After diversion cavity, volume reduces suddenly, and gaseous mixture flow velocity is accelerated, and rapidly enters in mixing chamber, and volume is larger suddenly, secondary gaseous mixture
Disperse in chamber is being mixed, flow velocity declines, and initially enters the flow velocity that the secondary gaseous mixture mixed in chamber has still continued diversion cavity,
It is impacted and is stirred to the combustion gas in mixing chamber, further increases the uniformity of secondary mixing；Secondary gaseous mixture is mixed
Sufficient mixing has been obtained in even chamber.Then burning is discharged via the flame hole on flame plate.
Due to the hole that wire netting is fine and close, secondary gaseous mixture is flowed again, in metal netlist when having fully ensured that burning
Face forms stabilization, uniform flame, in combustion process, again to the air that surrounding environment is filled into combustion gas, has fully ensured that combustion
The adequacy of burning, high combustion efficiency suppresses the generation of the flue gases such as carbon monoxide, oxynitrides well, environment-friendly.
