The utility model is by booster-type flameless burner 28, heat exchanger 4, and gas skirt 27, blast pipe 3 and electronic and electrical equipment, shell 1 grade four is partly formed.Booster-type flameless burner 28, heat exchanger 4 and gas skirt 27 have been formed the movement of water heater.The combustion gas throttle linkage 6 of booster-type flameless burner 28 is by gas inlet pipe 13, hollow shaft 14, movable valve 15, fixedly valve 16, connecting rod 17, push rod 18, be subjected to press mold 19, spring 20 is formed, and is set with movable valve 15 on hollow shaft 14 from top to bottom successively, fixedly valve 16, movable valve 15 is provided with pore 21 respectively on the fixed air 16, fixedly valve 16 and core shell 9 Joints, movable valve 15 is hinged with an end of push rod 18 by connecting rod 17, the other end of push rod 18 pass directly with the affixed press mold shell 22 of core shell 9 be subjected to press mold 19 one side centers affixed, spring 20 is sleeved on the interior push rod 18 of press mold shell 22, is provided with a combustion gas metering-orifice 23 on gas inlet pipe 13, gas inlet pipe 13 one tunnel links with the fixing import department of valve 16 back centrifugal fans 7, and another road enters and apply pressure to the another side that is subjected to press mold 19.Also can outside press mold shell 22, be connected with a connecting plate 24 affixed with core shell 9, simultaneously centers are affixed with being subjected to press mold 19 for push rod 18 1 ends, the other end is hinged by connecting rod 17 and movable valve, the other end at connecting plate 24 is provided with pilot hole 25, push rod 18 just passes pilot hole 25 and be provided with spring base 26 on push rod 18, and spring 20 just is located at 25 of spring base 26 and pilot holes.
If when the axis direction of centrifugal fan 7 and porous barrier 10 are vertical, available guide vane wheel 8, make wind direction all perpendicular to porous barrier 10.
As based on booster core shell 9, it is the tubbiness housing of a back-off, the bottom is last, there is an oblate projection centre, dome is smooth, uniform some scallop holes 21, formation one is valve 16 fixedly, and there is a hollow shaft 14 centre, and its upper sliding sleeve one is movable air throttle 15 with the duplicate disk of dome pass, adorn a shaft-use elastic gear ring with the fixed knot valve position in the active section valve outside, one micromotor 5 is arranged on the certain position at an upper portion thereof, use screw, be fixed on the core shell support at 9 ends, its output shaft stretches into housing 9 bottoms by hollow shaft 14, press-fit or with screw tightening one centrifugal fan 7, its air inlet is towards housing bottom fixed knot valve 16 at axle head.Have in centrifugal fan 7 outsides one with core shell 9 be connected around the air-flow guide vane wheel 8 of some arcuate guide blades is arranged, it makes the gaseous mixture of rotation at a high speed become downwards the axially air-flow of output, there is inner plane at 9 body lower openings places at the core shell, porous barrier 10 had both been adorned thereon, and on its periphery press-fits the base of the shell of heat exchanger 4, between porous inlet plate and heat exchanger, form the combustion chamber 11 that a little space is gaseous mixture, at the combustion chamber periphery, interior or outside be with one the circle water pipe, and with the seam of heat exchanger base, have two holes 30 in the vacancy of water pipe, 31, spark plug is installed in one hole, the ion plug is installed in one hole, join with impulse generator high-voltage line and amplifier input line respectively, combustion gas--throttle linkage 6 also is housed on the bottom of booster shell.
When connecting power supply opening turnover water valve, micromotor drives centrifugal fan 7 and rotates, the combustion G﹠W is realized the ratio supply of water and combustion gas through water-gas linkage 29, combustion gas is by combustion gas-throttle linkage 6, guarantee that combustion gas and air enter centrifugal fan 7 by proper ratio and mix and pressurize, when the gaseous-pressure that enters air inlet pipe 2 increases or reduces, gas pressure acts on pressure membrane 19, pressure membrane 19 can be epithelium, promote push rod 17 or move left to the right, when the air pressure on acting on epithelium equates with spring 20 pressure, push rod 17 stops in the relevant position, so just can make certain gas pressure guarantee combustion gas and the proportional burner that enters of air with regard to certain throttle opening is arranged.Make the gaseous mixture axial flow of rotation at a high speed through air-flow guide vane wheel 8, through porous barrier 10, porous barrier 10 can be porous ceramic plate or multiple layer metal web plate, and to enter combustion chamber 12 be that passages through which vital energy circulates charges and attacks fire burns, flow through heat exchanger 4 of high-temperature fuel gas is paid water with heat, chilled waste gas is discharged by the blast pipe on the gas skirt 27 3, and fresh air is then entered in the outer cover of water heater 1 by admission line 2.The movement of this water heater is an inversion type, working gas is the movement of flowing through from top to bottom, its reason is that the combustible gas mixing ratio is near 1, the high dew point height of water institute composition in the waste gas, can't overcome the water problems of coagulating on the heat exchanger blade, cause burner and the damage of its annex altogether for unlikely because of coagulating water, the movement of inversion type makes the water that coagulates drip to outdoor via blast pipe 3.This just need not to improve delivery temperature and solves water problems with fixed attention, has also improved the thermal efficiency of water heater simultaneously.Certain movement of the present utility model also can just be put, both the booster-type flameless burner also can be arranged on heat exchanger 4 belows, it is opposite when just its installation direction is inverted with movement fully, be that motor 5 is descending porous barrier 10 last, the superjacent air space of porous barrier 10 is combustion chamber 11, and following side space is a mixing chamber 12.
The utility model is when the axis direction of centrifugal fan 7 and porous barrier 10 are parallel, available guide vane 32, make wind direction all perpendicular to porous barrier 10, but motor 5 and combustion gas throttle linkage 6 homonymies or branch side are installed on the both sides of centrifugal fan 7, from core shell 9 outer wall gas inlet pipes 13 can be directly and hollow shaft 14 link, combustion gas enters centrifugal fan 7 equably.The core shell of booster is seeing it is a spiral case from the rotating shaft direction, its gas outlet is expanded into horn-like, multi-disc air-flow prerotation vane 32 is arranged in horn mouth, its water conservancy diversion direction all makes air-flow big extremely perpendicular to bell-mouthed porous barrier 10, there are air inlet and air throttle in one side center of its horn-like housing, motor, combustion gas--control valve linkage installation method such as preceding, just direction has changed.
Electronic centrifugal fan and combustion gas are being installed--the side plate of throttle linkage and these assemblies of installation can adopt side plate as an assembly, is screwed then on the big hole of leaving accordingly on the spiral case.Also can be with combustion gas--the throttle linkage offside is installed, and at this moment also fuel gas inlet can be connected on the hollow shaft 14 at air throttle center.
