Description

Condensing Gas Volumetric Water Heater

Technology area

The utility model relates to a gas volumetric water heater, in particular to a condensing gas volumetric water heater.

Background technique

With the continuous development of science and technology and the improvement of people's living standards, the demand for hot water in people's daily life has greatly increased. Water heaters and gas water heaters are widely used by people, especially gas volume water heaters have gradually entered thousands of households. . It uses gas combustion to heat up the water in the inner tank. However, due to the small heat exchange surface of the inner tank of the gas volumetric water heater, the high-temperature flue gas flow generated by combustion is short, and the exhaust temperature of the flue gas is high, so the loss of part of the heat cannot be fully realized. Utilization, resulting in low working thermal efficiency of the whole machine, low hot water production capacity per unit time, and high thermal load for heat preservation, resulting in a certain waste of heat energy. Therefore, a condensing gas-fired volumetric water heater has appeared, and its combustion releases The heat energy and high-temperature flue gas are firstly transferred through the lower cover of the inner tank combination for a heat exchange, and then under the retention of the flue stagnation sheet, they conduct a second heat exchange with the smoke exhaust pipe in the middle of the inner tank combination. The residual heat and high-temperature flue gas from the secondary heat exchange are blocked by the top cover of the counter-flow hood at the upper port of the exhaust pipe, reversed downward through the counter-flow hood, and exchange heat again with the outer wall of the enamel inner tank in the counter-flow cavity, and the residual heat and high-temperature flue gas are absorbed Fully absorbed, when the flue gas below the water vapor dew point temperature retrogrades to the lower end of the enamel liner, it is blocked by the water pan, the flue gas turns upward, and passes through the recirculation chamber formed by the recirculation hood and the recirculation hood, and the flue gas passes through the recirculation chamber again It goes back to the upper part of the return chamber and is blocked by the sealing ring of the return cover. At this time, the accumulated flue gas passes through the exhaust duct connected to the upper smoke port on the front of the return cover, the corresponding via holes on the shell and the exhaust on both sides of the front cover. The smoke hole is directly discharged to the outside of the water heater. Since the flue gas after combustion is directly discharged to the space from the flue exhaust duct in the middle of the gas water heater, the installation and use environment of this type of water heater is limited, and it must be installed in an environment suitable for the position of the flue exhaust duct, otherwise the use environment will be affected air quality.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings of the existing gas volumetric water heaters, and provide a condensing gas volumetric water heater, which has a simple structure, is safe and convenient to use, and can choose different exhaust gas directions according to the conditions and requirements of the use environment. Gas volumetric water heaters reduce the environmental requirements for installation and use, and reduce the impact on the air quality of the use environment.

In order to achieve the purpose of this utility model, such a technical solution is adopted: a condensing gas volumetric water heater, including an inner tank combination, an anode magnesium rod, a smoke pipe, a flue stagnation piece, a flue exhaust duct, a water heater insulation layer, a support Ring combination, shell upper cover, shell, shell lower cover combination, front cover combination, water inlet joint, water outlet joint, condensate water joint, temperature and pressure safety valve joint, back flow cover, return cover, return cover sealing ring, water pan, Water pan support ring, main burner assembly, gas control valve, reverse flow cover transition ring, reverse flow cover top cover, solar circulation return water joint, solar circulation water outlet joint, characterized by the left front side or left side of the aforementioned return flow cover The rear side or the right front side or the upper part of the right rear side is provided with a smoke port, and the aforementioned flue exhaust duct is arranged on the aforementioned shell opposite to the smoke port, and is connected with the smoke port on the return hood. A smoke exhaust hood is arranged on the shell at the end, and the smoke exhaust hood communicates with the smoke exhaust duct.

According to the condensing type high-efficiency gas volumetric water heater provided with a smoke exhaust hood provided by the utility model, during the normal working process of the water heater, the air required for combustion passes through the ventilation holes on both sides of the front cover, the through holes on the shell and the combination of the support ring. Through the hole into the combustion chamber; the flue stagnation piece is installed in the smoke pipe in the middle of the inner tank combination, and the upper port of the smoke tube has a counterflow cover top cover. Then, under the retention of the flue stagnation piece, the second heat exchange is carried out with the smoke tube in the liner combination; the waste heat and high-temperature flue gas that has passed the second heat exchange are blocked at the top of the counterflow hood at the upper port of the smoke tube After the lid is covered, it reverses downward through the counterflow hood, and exchanges heat with the outer wall of the liner combination in the counterflow cavity again. The waste heat and the heat of high-temperature flue gas are fully absorbed, and the flue gas that falls below the water vapor dew point temperature travels retrogradely to the liner combination. At the lower end, it is blocked by the water accumulation pan, and the flue gas turns upward, and passes through the return cavity formed by the return cover and the counter flow cover. The flue gas passes through the flue gas that is arranged in different directions on the return hood as required, the flue exhaust duct that communicates with it, and the flue gas exhaust hood on the outside of the shell to discharge the flue gas after the water heater is burned. The utility model has the advantages of simple structure, safe and convenient use. According to the conditions and requirements of the use environment, gas volumetric water heaters with different exhaust gas directions can be selected as needed, which reduces the environmental requirements for installation and use, and reduces the impact on the use of ambient air. quality impact.
