Abstract
A hot water supply type gas water heater comprises a finned tube heat exchanger and a combustion chamber. The finned tube heat exchanger is provided with a cold water inlet pipe and a hot water outlet pipe, and the finned tube heat exchanger is arranged on the top of the combustion chamber. The hot water supply type gas water heater is characterized in that the combustion chamber comprises a heat insulation tube and an outer cover, the heat insulation tube is opened up and down and is defined by four insulation boards, the outer cover is used for fixing the insulation boards, and the outer cover wraps the outer circumferential face of the heat insulation tube. By the adoption of the structure, compared with the prior art, a coiled tube is removed, the structure is simplified, and cost is lowered. Due to the fact that the heat insulation structure of the combustion chamber is adopted, heat can be prevented from radiating towards the inside of the water heater, heat loss is avoided, and heat efficiency is improved. For the reason that the coiled tube is removed, flue gas condensate water is avoided, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of gas heater.
Background technology
Prior art is a kind of at present
Supplying hot water type gas heater comprisesFin-tube type heat exchanger, combustion chamber and coil pipe have cold water inlet and hot water outlet pipe on the described fin-tube type heat exchanger; Fin-tube type heat exchanger is arranged on the top of combustion chamber.The one, running water from water valve body out after, pass through first coil pipe, then enter fin-tube type heat exchanger, discharge water heater from outlet pipe afterwards, the advantage of this structure is that the water tank wall surface temperature is lower, be conducive to the coil pipe absorbing heat, improve the thermal efficiency, shortcoming is that the water tank wall face is prone to flue gas condensing water, the corrosion water heater.The 2nd, running water from water valve body out after, be introduced into fin-tube type heat exchanger, then pass through coil pipe, discharge water heater from outlet pipe afterwards, the advantage of this structure is that wall surface temperature is higher, generally condensed water can not occur, but wall surface temperature is higher, the water heater radiation loss is larger, is unfavorable for that the thermal efficiency promotes, and higher to the water heater internal temperature, normal operation may have certain influence to electronic control circuit.
Summary of the invention
The purpose of this utility model is: a kind of supplying hot water type gas heater is provided, and it can prevent radiation loss, can prevent the flue gas condensing water generates again and corrodes water heater.
The utility model is achieved in that a kind of
Supplying hot water type gas heater comprisesThere are cold water inlet and hot water outlet pipe in fin-tube type heat exchanger and combustion chamber on the described fin-tube type heat exchanger; Fin-tube type heat exchanger is arranged on the top of combustion chamber; Described combustion chamber comprises the insulation cylinder of the upper and lower opening that is surrounded by four thermal insulation boards and the fixing overcoat of thermal insulation board;
The outer circumferential surface of described overcoat parcel insulation cylinder.
Described a kind of
Supplying hot water type gas heater, its special character is: described overcoat is made by sheet metal;
The lower surface of the in-flanges covering and heat insulating heat insulation cylinder of overcoat lower end is also stretched in the insulation cylinder, and the inner surface of in-flanges and insulation cylinder is fitted.
The utility model is a kind of
Supplying hot water type gas heater owing to adopt such structure, compared with prior art, has saved coil pipe, simplifies the structure, and has reduced cost; The structure of insulation is adopted in the combustion chamber, can prevent that heat from distributing in water heater, causes thermal loss, has improved the thermal efficiency; Save coil pipe, prevented the generation of flue gas condensing water, prolonged service life.
Description of drawings
Fig. 1 is front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of
Supplying hot water type gas heater comprisesThere are cold water inlet 11 and hot water outlet pipe 12 in fin-tube type heat exchanger 1 and combustion chamber 2 on the described fin-tube type heat exchanger 1; Fin-tube type heat exchanger 1 is arranged on the top of combustion chamber 2; Described combustion chamber 2 comprises the insulation cylinder 21 of the upper and lower opening that is surrounded by four thermal insulation boards and the fixing overcoat 22 of thermal insulation board, and described combustion chamber comprises the insulation cylinder of upper and lower opening and the fixing overcoat of thermal insulation board,
The outer circumferential surface of described overcoat 22 parcel insulation cylinders 21.
Described insulation cylinder 21 has resistant to elevated temperatures function.
Described overcoat 22 is made by sheet metal;
The lower surface of the in-flanges 23 covering and heat insulating heat insulation cylinders 21 of overcoat 22 lower ends is also stretched in the insulation cylinder 21, and in-flanges 23 is fitted with the inner surface of insulation cylinder 21.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art in the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
