Description

The condensed type combustion gas displacement type water heater

Technology neck city

The utility model relates to a kind of gas displacement type water heater, especially a kind of condensed type combustion gas displacement type water heater.

Background technology

Along with the continuous development of science and technology, the improvement day by day of people's living standard, the demand of hot water in people's daily life increases greatly, and water heater, gas heater are extensive use of by people, and especially gas displacement type water heater has been come into huge numbers of families gradually.It adopts the burning of combustion gas, water in the inner bag is carried out heat temperature raising, but because gas displacement type water heater inner bag heat-transfer surface is little, the high-temperature flue gas flow process that burning produces is short, flue gas exhaust gas temperature height, forfeiture part heat can not make full use of, thereby cause complete machine working heat efficient low, the heat production outlet capacity is low in unit interval, and insulation maintaining heat load is higher, thereby produce certain thermal waste, thereby a kind of condensed type combustion gas displacement type water heater appearred, heat energy that its burning discharges and high-temperature flue gas at first carry out a heat exchange by the inner bag lower cover transmission of inner bag combination, subsequently under the delay effect of the stagnant sheet of flue, carry out the secondary heat exchange with inner bag combination middle part smoke exhaust pipe again, waste heat by the secondary heat exchange and high-temperature flue gas are after the smoke exhaust pipe upper port is hampered by adverse current cover top cover, reverse downwards by the adverse current cover, in the adverse current chamber, carry out heat exchange once more with the enamel inner container outer wall, waste heat and high-temperature flue gas are fully absorbed, reduce to the following flue gas of water vapour dew-point temperature when driving in the wrong direction to the enamel inner container bottom, be hampered by the ponding dish, flue gas rotary upwards, back cavity by reflux cover and the hood-shaped one-tenth of adverse current, flue gas is once more by the contrary back cavity top that is back to of back cavity, be hampered by the cover sealing ring that refluxes, at this moment, the flue gas of accumulation is again by covering the smokejack that the front upper mouth links to each other with backflow, the exhaust smoke hole of corresponding via hole on the shell and front shroud two upper lateral parts directly drains into outside the water heater.Since its gas fume after burning directly from the middle part smokejack of gas heater to space drainage, therefore the environment of installing and using of such water heater is restricted, the environment that adapts with the smokejack position must be installed in, otherwise the air quality of environment for use will be influenced.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of existing gas displacement type water heater, a kind of condensed type combustion gas displacement type water heater is provided, it is simple in structure, safe and convenient to use, can be according to the conditional request of environment for use, select the gas displacement type water heater of different smoke discharging directions as required, reduce its environmental requirement, reduce influence the environment for use air quality to installing and using.

For realizing that the purpose of this utility model has adopted such technical scheme: a kind of condensed type combustion gas displacement type water heater, include the inner bag combination, anodic magnesium rod, smoke pipe, the flue sheet that stagnates, smokejack, the water heater heat-insulation layer, the support ring combination, outer casing upper cover, shell, the combination of shell lower cover, the front shroud combination, water supply connector, water out adapter, the condensed water joint, temperature, pressure safety valve joint, the adverse current cover, cover refluxes, the cover sealing ring refluxes, the ponding dish, the ponding dish props up seat ring, the main burner assembly, gas control valve, adverse current cover transition circle, adverse current cover top cover, solar energy circulating backwater joint, solar energy cyclic water outlet joint, it is characterized in that the front left side of aforesaid backflow cover or the top of left rear side or forward right side or right lateral side are provided with mouth, position relative with this mouth on aforesaid shell is provided with aforesaid smokejack, and the mouth that covers with backflow leads to, the shell of smokejack outer end is provided with enclosure, and this enclosure and smokejack lead to.

By the condensing type highly effective gas displacement type water heater that enclosure is arranged that the utility model provides, in the water heater course of normal operation, the required air that burns enters in the combustion chamber by the via hole in via hole on front shroud both sides air vent, the shell and the support ring combination; The stagnant sheet of flue is contained in the smoke pipe at inner bag combination middle part, the smoke pipe upper port has adverse current cover top cover, heat energy that its burning discharges and high-temperature flue gas at first carry out a heat exchange by the transmission of inner bag combination lower cover, under the delay effect of the stagnant sheet of flue, the smoke pipe in making up with inner bag again carries out the secondary heat exchange subsequently; Waste heat by the secondary heat exchange and high-temperature flue gas are after the smoke pipe upper port is hampered by adverse current cover top cover, reverse downwards by the adverse current cover, in the adverse current chamber, carry out heat exchange once more with inner bag combination outer wall, the heat of waste heat and high-temperature flue gas is fully absorbed, reduce to the following flue gas of water vapour dew-point temperature when driving in the wrong direction to inner bag combination bottom, be hampered by the ponding dish, flue gas rotary upwards, back cavity by reflux cover and the hood-shaped one-tenth of adverse current, flue gas is once more by the contrary back cavity top that is back to of back cavity, be hampered by the cover sealing ring that refluxes, at this moment, the flue gas of building up is arranged on the mouth of different directions and the smokejack that interlinks with it as required by covering with backflow again, enclosure on the shell outside is discharged this water heater gas fume after burning.Of the present utility model simple in structure, safe and convenient to use, can be according to the conditional request of environment for use, select the gas displacement type water heater of different smoke discharging directions as required, reduced its environmental requirement, reduced influence the environment for use air quality to installing and using.
