Abstract
The invention relates to an energy-saving type gas water heater which comprises an outer shell. A burner is arranged in the outer shell, 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, and a hot water opening is formed in the other side of the hot water tank; a smoke vent is formed in the top of the outer shell, a preheating water tank is arranged on the cold water opening, a smoke exhaust pipeline is arranged in the preheating water tank, the outlet of the smoke exhaust pipeline is connected with the smoke vent, and the inlet of the smoke exhaust pipeline is located above a gas opening. By the adoption of the structure, hot air after gas water heater burns is fed into cold water which is not heated, so the cold water can be preheated, gas needing to be heated is saved, heating efficiency can be improved, and heat energy resources after the gas burns are sufficiently utilized.
Description
Technical field
The present invention relates to field of water heaters, especially relate to a kind of energy-saving gas heater.
Background technology
Gas heater claims again gas water-heating furnace, and it refers to combustion gas and act as a fuel, and by the 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 purpose for 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 now is also with a large amount of heats, so just cause a lot of wastes, can not take full advantage of resource.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of energy-saving gas water heater that can take full advantage of the rear air heat of burning.
The present invention solves the technical scheme that its technical problem takes: 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, be provided with boiler above burner, a side at boiler is provided with cold water outlet, be provided with the hot water mouth at opposite side, case top is provided with exhaust opening outside, described cold water outlet place is provided with the preheating water tank, be provided with smoke discharging pipe in the preheating water tank, 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 the preheating water tank.
Further concrete, the air flow in described smoke discharging pipe is contrary with the flow direction in the preheating water tank.
Further concrete, the outside of described boiler is provided with heat-insulation layer.
The invention has the beneficial effects as follows: after having adopted said structure, hot-air after the 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, take full advantage of the heat resource after fuel gas buring.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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, be provided with burner 7 in shell body 1 inside, in the other igniter 6 that is provided with of burner 7, be provided with boiler 4 above burner 7, a side at boiler 4 is provided with cold water outlet 8, be provided with hot water mouth 5 at opposite side, be provided with exhaust opening 3 at shell body 1 top, described cold water outlet 8 places are provided with preheating water tank 9, be provided with smoke discharging pipe 2 in preheating water tank 9, 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 takes full advantage of the heat after the 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, reduce the time to hot water by cool water heating, facilitates bathing.
It is emphasized that: above is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
