Embodiment Construction

[0034] figure 1 It is a schematic structural diagram of a condensing gas water heater according to an embodiment of the present invention. The arrows in the figure indicate the flow direction of the smoke. As those skilled in the art can recognize, 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 condensing heat exchanger 18 above, 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 burner group 8 can be arranged in the combustion chamber defined by the combustion chamber shell 30; in the flue gas heat exchange chamber. The flue gas heat exchange chamber is arranged above the combustion chamber, and i...

Abstract

The invention provides a condensation type gas water heater which comprises a flue gas heat exchanging chamber, a condensation heat exchanger arranged in the flue gas heat exchanging chamber, and an atomization device, wherein the atomization device is used for collecting condensate water dropping from the condensation heat exchanger, atomizing the collected condensate water, and discharging the atomized condensate water out of the condensation type gas water heater along with flue gas. According to the invention, the atomization device is arranged, so that water steam releases latent heat to convert into liquid water, the liquid water is atomized and then discharged out of the condensation type gas water heater along with the flue gas, liquid-state condensate water is prevented from dropping, the condensation type gas water heater operates more reliably, the potential risk caused by indoor discharging of acid condensate water is avoided at the same time, and the condensation type gas water heater has higher safety. The condensation type gas water heater is not provided with a condensate water drain pipe, so that the condensation type gas water heater is attractive in appearance and convenient to use, and has better user experience after installation.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a condensing gas water heater. Background technique [0002] After a heat exchange, the gas water heater usually produces medium-temperature flue gas with a temperature of about 180°C, and the CO in the medium-temperature flue gas 2 , NO X The content of water vapor is high and has high heat energy content. If it is directly discharged, it will not only pollute the environment, but also cause 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 medium-temperature flue gas, improves the utilization rate of the gas, and greatly reduces the temperature of the flue gas discharged outside the machine. Since the water vapor in the medium-temperature flue gas will condense into liquid condensed water while releasing latent heat, and the CO in the flue gas 2 , NO ...
