Referring to fig. 1, a zero cold water gas heater of condensing, including shell 1, install combustion chamber 2, heat exchanger 3, the system 4 and the circulating water pump 5 of discharging fume in shell 1, still be equipped with water inlet 11, delivery port 12 and exhaust port 13 on the shell 1, still include condensing heat exchanger 6, condensing heat exchanger 6 installs between system 4 and the exhaust port 13 of discharging fume, heat exchanger 3 includes coil pipe heat transfer mechanism and fin heat transfer mechanism, fin heat transfer mechanism sets up on combustion chamber 2, coil pipe heat transfer mechanism sets up outside combustion chamber 2, be equipped with the water route in shell 1, the water route is through water inlet 11, circulating water pump 5, coil pipe heat transfer mechanism, condensing heat exchanger 6, fin heat transfer mechanism and delivery port 12 in proper order. And a condensed water processing box 7 is also arranged at the lower part of the shell 1, and the condensed water processing box 7 is communicated with the condensing heat exchanger 6 through a condensed water pipe 8. Still include main control unit 9 in the shell 1, still establish sensor 10 on the water inlet, circulating water pump 5 and sensor 10 all are connected with main control unit 9 electricity.

When the water heater works, the gas is introduced into the water heater and then ignited, so that the gas is combusted in the combustion chamber to generate heat, then the water flows through the heat exchanger and is heated, and hot water is generated at the water outlet. And the combustion chamber will produce a large amount of high temperature waste gas in the combustion process to and the heat in the combustion process can be because the outer wall of combustion chamber has been heated to the thermal radiation, consequently, cold water is at first through coil pipe heat exchanger this time primary heating after getting into the water heater, retrieves the heat of the outer wall of combustion chamber.

The water enters the condensing heat exchanger, and after passing through the condensing heat exchanger, the water recovers the heat of the high-temperature waste gas, and meanwhile, because cold water passes through the coil heat exchanger, the temperature difference between the condensing heat exchanger and the water is reduced, so that the generation of condensed water can be reduced. Since the condensed water produced by the condensing heat exchanger is a harmful liquid with acidity, the condensed water corrodes the heat exchanger and causes damage to the environment. Therefore, smaller condensate production will be more environmentally friendly. Meanwhile, the recovered condensed water is neutralized and collected by the condensed water processing box. The condensed water is convenient to treat.

The hot water heated by the condensing heat exchanger is heated by the fin heat exchange mechanism, and the gas directly heats the fin heat exchange mechanism, so that the water temperature rises most obviously in the process, and the water is heated and then discharged from the water outlet. Therefore, cold water passes through the heat exchange mechanism for many times in the water heater, so that the heat generated by gas combustion is more fully utilized.

When the user does not use hot water, cold water in the water channel flows in a circulating mode through the circulating water pump 5, and then the water in the water channel is heated by the water heater, so that the user can directly discharge hot water when using the water heater, and the effect of zero cold water is achieved. And the user is when normal water using, because circulating water pump is established ties on the water route, can play the effect of pressure boost through circulating water pump, improves user's water pressure.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
