Abstract

The invention discloses a non-premixing inverted condensing gas water heater which comprises a shell, a fume pipe cavity, a fan, a water valve, a gas valve and a heat exchanger; a combustor box is arranged on the upper part of the shell, more than two groups of combustors are arranged in the combustor box, a fume shade is arranged on the lower part of the combustor box, the fan is arranged at the lower end of the fume shade and connected with the fume pipe cavity by fume pipes; the fume pipe cavity is internally provided with one or more than one group of spiral heat exchanging pipes which are communicated with the water valve and the heat exchanger to form the inverted combustion structure; and simultaneously the fume pipe cavity is used as a condenser. The invention can solve the problem that the condensate water corrodes and blocks the heat exchanger, can reduce the manufacture and use costs, and has obvious energy-saving effect.

Description

Non-premixing inverted condensing gas water heater
Technical field:
The present invention relates to a kind of gas heater, a kind of non-premixing inverted condensing gas water heater of more specifically saying so.
Background technology:
Gas heater is with the favor of the extremely numerous families of convenient, fast, the round-the-clock advantage that can both use, in the prior art, the most of atmospheric burning type mode that adopts of gas heater, combustion gas and air are combined in the burner through secondary mixing and burn, the flue-gas temperature of its discharge is too high, mostly more than 110 ℃, a lot of heats are not fully utilized and waste; The condensed type combustion gas water heater that existing market is sold often adopts heat exchanger and the conjuncted structure of condenser, be inverted the full premix combustion mode, remarkable energy saving effect is arranged, but manufacturing cost height, complex structure has hindered product and has popularized and development, increase financial burden to the user, become the bottleneck of production development.
Summary of the invention:
Purpose of the present invention is exactly the non-premixing inverted condensing gas water heater of provide for the deficiency that solves prior art a kind of simple in structure, low cost of manufacture, obvious energy conservation.
The deal with problems technical scheme that adopted of the present invention is achieved in that and the present invention includes housing, smoke pipe chamber, blower fan, water valve, gas valve and heat exchanger; It is characterized in that: the burner box is settled on the top at housing, and inside is provided with two groups of above burners; On the heat exchanger of bottom petticoat pipe is set, blower fan is placed in the petticoat pipe lower end, connects with the smoke pipe chamber by smoke-intake pipe; Be provided with a group or more spiral heat exchange tube in the smoke pipe chamber, the heat exchanger tube inlet side connects with water valve by the water inlet connecting tube, goes out end and communicates with heat exchanger by the water outlet connecting tube; The gas distributing rod of burner is provided with two groups of above gas nozzles, and the burner fire hole is inverted, and has the igniting pin on the fire hole; Upper end, smoke pipe chamber is a smoke exhaust pipe, and the bottom is the condensation mouth of a river.
The present invention compared with the prior art, beneficial effect is embodied in:
1, settle the burner box on the top of housing of the present invention, inside is provided with two groups of above burners; The bottom is provided with petticoat pipe, and blower fan is placed in the petticoat pipe lower end, connects with the smoke pipe chamber by smoke-intake pipe, forms and is inverted burning structure, simultaneously the smoke pipe chamber is used as condenser, has solved the difficult problem of condensed water corrosion and blocking heat-exchanger, has reduced manufacturing cost.
2, the present invention is provided with a group or more spiral heat exchange tube in inside, smoke pipe chamber, and communicates with water valve and heat exchanger respectively, forms simple compact water channel.
3, simple in structure, the energy savings of the present invention, installation, maintenance, use are all very convenient.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a burner structure schematic diagram of the present invention;
Fig. 3 looks up structural representation for burner of the present invention;
By the following examples, in conjunction with the accompanying drawings the present invention is further described;
Description of reference numerals: 1-pipe, 2-burner box, 3-housing, 4-combustion chamber, 5-heat exchanger, 6-petticoat pipe, 7-blower fan, 8-Gas Pipe, 9-hot water outlet, 10-gas valve, 11-fuel gas inlet, 12-water valve, 13-cooling water inlet, 14-water inlet connecting tube, the 15-condensation mouth of a river, 16-heat exchanger tube, 17-smoke-intake pipe, 18-smoke pipe chamber, 19-water outlet connecting tube, 20-gas distributing rod, 21-burner, 22-fire hole, 23-gas nozzle, the 24-pin of lighting a fire;
Embodiment: referring to accompanying drawing 1,2,3; The present invention includes housing (3), smoke pipe chamber (18), blower fan (7), water valve (12), gas valve (10) and heat exchanger (5); Burner box (2) is settled on top at housing (3), and inside is provided with three groups of burners (21); The heat exchanger of bottom (5) top is provided with petticoat pipe (6), and blower fan (7) is placed in petticoat pipe (6) lower end, connects with smoke pipe chamber (18) by smoke-intake pipe (17); Inside, smoke pipe chamber (18) is provided with two groups of spiral heat exchange tubes (16), and heat exchanger tube (16) inlet side connects with water valve (12) by water inlet connecting tube (14), goes out end and communicates with heat exchanger (5) by water outlet connecting tube (19); The gas distributing rod (20) of burner (21) is provided with three groups of gas nozzles (23), and burner (21) fire hole (22) is inverted, and has igniting pin (24) on the fire hole (22), and smoke pipe chamber (18) upper end is pipe (1), and the bottom is the condensation mouth of a river (15).
During use, running water and combustion gas are connected in respectively on cooling water inlet (13) and the fuel gas inlet (11), open the water source, start-up control part (not drawing among the figure), blower fan (7) work, igniting pin (24) igniting, combustion gas enters in the burner (21) by gas valve (10) and Gas Pipe (8), because burner (21) is inverted, flame burns in combustion chamber (4) from fire hole (22) ejection; The burned on every side device box of burner (21) (2) parcel, air can only (direction of arrow) enter from top, and the high-temperature flue gas that produces during burning enters smoke pipe chamber (18) through petticoat pipe (6), blower fan (7) by smoke-intake pipe (17), discharges from pipe (1); Cold water enters water valve (12) from cooling water inlet (13) simultaneously, in water inlet connecting tube (14) enters heat exchanger tube (16) in the smoke pipe chamber (18) and high-temperature flue gas carry out heat exchange, heat in the flue gas is fully used, water after the preheating heats through water outlet connecting tube (19) inflow heat exchanger (5) again, and the hot water of formation flows out for people to use from hot water outlet (9); Because as condenser, structure is very simple, and does not produce condensed water in the heat exchanger (5), has solved corrosion and the obstruction of condensed water to heat exchanger (5) with smoke pipe chamber (18), the condensed water that smoke pipe chamber (18) produces is discharged from bottom condensate water mouth (15).
