Embodiment Construction
[0028] figure 1 It is a schematic structural diagram of a condensing gas water heater according to an embodiment of the present invention. The small arrow in the figure indicates the direction of water flow, and the large arrow indicates the direction of flue gas flow. As can be appreciated by those skilled in the art, the condensing gas water heater of the embodiment of the present invention, like the existing conventional condensing gas water heater, also includes a gas distributor 6 and its upper burner group 8, a main heat exchanger 14 and its The upper condensing heat exchanger 18, the water inlet pipe 26 and the flow sensor 28 arranged on the water inlet pipe 26, the gas inlet pipe 22, the gas proportional valve 24, the hot water outlet pipe 2 and the temperature sensor 10 arranged thereon. The gas distributor 6 and the combustor group 8 may be arranged in the combustion chamber defined by the combustion chamber shell 30; the main heat exchanger 14 and the condensation he...

The invention provides a condensation type gas water heater. The condensation type gas water heater comprises a smoke heat exchange cavity shell and a condensation heat exchanger arranged in the smoke heat exchange cavity shell. The condensation type gas water heater further comprises a gasification device, and the gasification device is arranged in the smoke heat exchange cavity shell and located below the condensation heat exchanger so that condensate water dripping from the condensation heat exchanger can be gasified. The gasification device is additionally arranged between the condensation heat exchanger and a main heat exchanger, after releasing latent heat and becoming liquid water, steam can be gasified again and exhausted out of the heater along with smoke, and liquid condensate water is prevented from dripping down. The potential danger brought by discharging of acid condensate water indoors in the prior art is avoided, and high safety is achieved. A condensate water discharge pipe does not need to be arranged in the condensation type gas water heater any more, and after installing, attractiveness is achieved, meanwhile, using is convenient, and the user experience is good.
Description
Technical field [0001] The invention relates to a gas water heater, in particular to a condensing gas water heater. Background technique [0002] After the gas water heater performs a heat exchange, it usually produces medium temperature flue gas with a temperature generally around 180 ℃, and CO in the medium temperature flue gas 2 , NO X The water vapor with high content and high heat energy content, if directly discharged, not only pollutes the environment, but also causes a large amount of heat energy loss. The condensing gas water heater uses a condensing heat exchange device for secondary heat exchange, preheats the water, recovers the latent heat of the mid-temperature flue gas, improves the utilization rate of the gas, and greatly reduces the temperature of the flue gas discharged outside the machine. Because the water vapor in the medium temperature flue gas will condense into liquid condensate while releasing latent heat, and the CO in the flue gas 2 , NO X Other acid ga...
