Abstract

The utility model relates to an energy-saving gas water heater which comprises an outer shell body. A combustor is arranged in the outer shell body. An ignition device is arranged beside the burner. A hot water tank is arranged above the burner. A cold water opening is formed in one side of the hot water tank. A hot water opening is formed in the other side of the hot water tank. A smoke discharging opening is formed in the top of the outer shell body. A preheating water tank is arranged at the cold water opening. A smoke discharging channel is arranged in the preheating water tank. An outlet of the smoke discharging channel is connected with a smoke discharging opening. An inlet of the smoke discharging channel is placed above a gas opening. After the structure is used, hot air after burning through the gas water heater goes into cold water which is not heated, the cold water can be preheated, gas needed for heating is saved, heating efficiency is improved, and heat energy resources after gas burning are fully used.

Description

Energy-saving gas water heater
Technical field
The utility model relates to field of water heaters, especially relates to a kind of energy-saving gas heater.
Background technology
Gas heater claims again gas water-heating furnace, and it refers to usings combustion gas as fuel, by combustion heating mode, heat is delivered in the cold water of the heat exchanger of flowing through to reach a kind of gas appliance of the object of preparing hot water.Its advantage is exactly plug and play, and without wait, and floor space is less, can save a lot of spaces, and gas heater is discharged through exhaust opening through the air of burning at present, and air is now also with a large amount of heats, so just cause a lot of wastes, can not make full use of resource.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energy-saving gas water heater that can make full use of the rear air heat of burning.
The technical scheme in the invention for solving the technical problem is: a kind of energy-saving gas water heater, comprise shell body, enclosure interior is provided with burner outside, in the other igniter that is provided with of burner, above burner, be provided with boiler, a side at boiler is provided with cold water outlet, at opposite side, be provided with hot water mouth, case top is provided with exhaust opening outside, described cold water outlet place is provided with preheating water tank, in preheating water tank, be provided with smoke discharging pipe, the outlet of smoke discharging pipe is connected with exhaust opening, and the import of smoke discharging pipe is positioned at the top of burner.
Further concrete, described smoke discharging pipe is crooked coiling in preheating water tank.
Further concrete, the air flow in described smoke discharging pipe is contrary with the flow direction in preheating water tank.
Further concrete, the outside of described boiler is provided with heat-insulation layer.
The beneficial effects of the utility model are: after having adopted said structure, hot-air after gas heater burning is passed in the cold water that there is no heating, can makes cold water heat in advance, save the combustion gas of required heating, can improve the efficiency of heating surface, make full use of the heat resource after fuel gas buring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, shell body; 2, smoke discharging pipe; 3, exhaust opening; 4, boiler; 5, hot water mouth; 6, igniter; 7, burner; 8, cold water outlet; 9, preheating water tank.
The specific embodiment
A kind of energy-saving gas water heater as shown in Figure 1, comprise shell body 1, in shell body 1 inside, be provided with burner 7, in the other igniter 6 that is provided with of burner 7, above burner 7, be provided with boiler 4, a side at boiler 4 is provided with cold water outlet 8, at opposite side, be provided with hot water mouth 5, at shell body 1 top, be provided with exhaust opening 3, described cold water outlet 8 places are provided with preheating water tank 9, in preheating water tank 9, be provided with smoke discharging pipe 2, the outlet of smoke discharging pipe 2 is connected with exhaust opening 3, and the import of smoke discharging pipe 2 is positioned at the top of burner 7; Described smoke discharging pipe 2 is in the interior crooked coiling of preheating water tank 9; Air flow in described smoke discharging pipe 2 is contrary with the flow direction in preheating water tank 9; The outside of described boiler 4 is provided with heat-insulation layer.
Said structure makes full use of the heat after gas heater burning, and the hot-air of discharge is collected by smoke discharging pipe 2 cold water to not heating and preheated, and takes full advantage of heat, and the air themperature of discharge reduces; Through pre-warmed cold water, time shorten when again heating, reduces the time to hot water by cool water heating, facilitates bathing.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
