Abstract
The utility model relates to a kind of round trip domestic gas-fired water heater in field of water heaters, and be provided with dividing plate in its housing, dividing plate upper end is connected with housings close, and interface channel is left in dividing plate lower end, and combustion chamber is arranged on dividing plate side, and dividing plate opposite side is baffling passage; Be connected with serpentine coil through spiral coil between inlet suction port and water supply connector, spiral coil integrated straight is vertical to be arranged in combustion chamber, and burner is arranged on case top, and gas nozzle is inserted into the upper port position of the spiraled cavity that spiral coil is formed downwards; Serpentine coil is arranged in baffling passage, and baffling channel roof is connected with smoke exhaust pipe.During work, combustion gas is in spiraled cavity combustion and heat exchange, and the flue gas after burning then enters baffling passage by interface channel, and in baffling passage, the further heat exchange of water in flue gas and serpentine coil, own temperature reduces further, then discharges from smoke exhaust pipe.This device can fully heat exchange, effectively reduces exhaust gas temperature, reaches the effect of heat energy efficiency utilization.
Description
Technical field
The utility model relates to a kind of water heater, particularly a kind of gas heater.
Background technology
In prior art, there is a kind of domestic gas-fired water heater, its structure comprises housing, housing is provided with smoke exhaust pipe, inlet suction port, water supply connector and water out adapter, is provided with heat exchanger between water supply connector and water out adapter, and inlet suction port connects burner, described burner comprises the gas nozzle, blower fan and the ignitor that are connected with inlet suction port, be provided with combustion chamber in housing, heat exchanger is arranged in combustion chamber, and smoke exhaust pipe is connected to the exit position of combustion chamber.This device, by combustion gas, is absorbed heat by heat exchanger, and heat transfer is to the water of its inside, and the water after heating is available.Its weak point is: owing to directly discharging fume after fuel gas buring, and the heat in flue gas is not fully absorbed, and causes energy loss larger.
Utility model content
The purpose of this utility model is to provide a kind of round trip domestic gas-fired water heater, can more fully absorb heat, and reduces exhaust gas temperature.
The purpose of this utility model is achieved in that a kind of round trip domestic gas-fired water heater, comprise housing, housing is provided with smoke exhaust pipe, inlet suction port, water supply connector and water out adapter, inlet suction port connects burner, described burner comprises the gas nozzle, blower fan and the ignitor that are connected with inlet suction port, combustion chamber is provided with in housing, dividing plate is provided with in described housing, dividing plate upper end is connected with housings close, interface channel is left in dividing plate lower end, combustion chamber is arranged on dividing plate side, and dividing plate opposite side is baffling passage; Be connected with serpentine coil through spiral coil between described inlet suction port and water supply connector, described spiral coil integrated straight is vertical to be arranged in combustion chamber, burner is arranged on case top, and gas nozzle is inserted into the upper port position of the spiraled cavity that spiral coil is formed downwards; Serpentine coil is arranged in baffling passage, and baffling channel roof is connected with smoke exhaust pipe.
During utility model works, the spiraled cavity combustion that combustion gas is formed at spiral coil, the heat produced passes to the water in spiral coil, flue gas after burning then enters baffling passage by interface channel, in baffling passage, the further heat exchange of water in flue gas and serpentine coil, after own temperature reduces further, flue gas is discharged from smoke exhaust pipe.Compared with prior art, the utility model flue gas, then to be discharged fume to smoke exhaust pipe through baffling passage from combustion chamber through interface channel, and what it was walked is round trip; What water was walked in spiral coil and serpentine coil is also round trip; Can fully heat exchange, effectively reduce exhaust gas temperature, make full use of the heat energy after fuel gas buring, reach the effect of heat energy efficiency utilization.
For avoiding housing outwards to dispel the heat, described inner walls is provided with thermal insulation layer.
In order to prevent flame Jet with downward flow direction from causing scaling loss on housing or thermal insulation layer, the inner walls below described spiral coil is fixed with anti-yaw damper plate.
For ensureing flame stabilization further, described gas nozzle lower end is provided with stable flame pan.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 dividing plate, 2 serpentine coils, 3 baffling passages, 4 water supply connectors, 5 smoke exhaust pipes, 6 ignitors, 7 inlet suction ports, 8 blower fans, 9 gas nozzles, 10 stable flame pans, 11 water out adapters, 12 spiral coils, 13 thermal insulation layers, 14 combustion chambers, 15 housings, 16 interface channels, 17 anti-yaw damper plates.
Detailed description of the invention
As shown in Figure 1, be round trip domestic gas-fired water heater, comprise housing 15, housing 15 inwall is provided with thermal insulation layer 13; Housing 15 is provided with smoke exhaust pipe 5, inlet suction port 7, water supply connector 4 and water out adapter 11, inlet suction port 7 connects burner, described burner comprises the gas nozzle 9, blower fan 8 and the ignitor 6 that are connected with inlet suction port 7, gas nozzle 9 lower end is provided with stable flame pan 10, ignitor 6 extend into gas nozzle 9 side, combustion chamber 14 is provided with in housing 15, dividing plate 1 is provided with in housing 15, dividing plate 1 upper end is closed with housing 15 and is connected, interface channel 16 is left in dividing plate 1 lower end, combustion chamber 14 is arranged on dividing plate 1 side, and dividing plate 1 opposite side is baffling passage 3; Be connected with serpentine coil 2 through spiral coil 12 between inlet suction port 7 and water supply connector 4, spiral coil 12 integrated straight is vertical to be arranged in combustion chamber 14, burner is arranged on housing 15 top, and gas nozzle 9 is inserted into the upper port position of the spiraled cavity that spiral coil 12 is formed downwards; Serpentine coil 2 is arranged in baffling passage 3, and baffling passage 3 top is connected with smoke exhaust pipe 5.Housing 15 inwall below spiral coil 12 is fixed with anti-yaw damper plate 17.
During the work of this device, the spiraled cavity combustion that combustion gas is formed at spiral coil 12, the heat produced is passed to the water in spiral coil 12, flue gas after burning then enters baffling passage 3 by interface channel 16, in baffling passage 3, the further heat exchange of water in flue gas and serpentine coil 2, after own temperature reduces further, flue gas is discharged from smoke exhaust pipe 5.Flue gas, then to be discharged fume to smoke exhaust pipe 5 through baffling passage 3 from combustion chamber 14 through interface channel 16, and what it was walked is round trip; What water was walked in spiral coil 12 and serpentine coil 2 is also round trip; Can fully heat exchange, effectively reduce exhaust gas temperature, make full use of the heat energy after fuel gas buring, reach energy-conservation effect.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
