The utility model is characterized in that the outer shell of the boiler forms a closed annular insulating water tank with the inner shell of the boiler, the annular duct of a boiler cavity is arranged on the inner wall of the inner shell of the boiler body, the upper part of the annular duct of a boiler cavity is provided with a heat water tank, and the middle part of the heat water tank is provided with a flue. The utility model has the characteristics of small size, large area of heat transmission, large amount of hot water supply, no pollution and safe use.

Description

Domestic gas boiler

The utility model relates to a kind of domestic heating device, specifically is meant domestic gas boiler.

Existing heating system has following a few class: a class is that these class methods are more original, and are both unhygienic, dangerous again by burning or directly heating of heating; With electric heating cost height not only, and the thermal efficiency is low, is not suitable for the larger area heating.Two classes are outside calefactory, and burning heating heat transfer medium (steam or water) is by discharging heat energy to heat transfer medium input heating room, reach the effect of heating,, be widely used as central heating system, but investment takies building site greatly, and seriously polluted, is difficult for using flexibly.Three classes are family expenses oil burning boilers, reach the heating purpose by oil firing, though this type of boiler is easy to use, heating effect good, involve great expense, and usage charges height, complex structure, volume be big, be difficult for promoting the use of.Four class combustion gas heating installations, as gas heater, its structure is that gas combustion apparatus is directly installed on the water heater, carries out heating service.Because the furnace tube internal memory water yield of water heater is few, be unsuitable for the heating of large-area room.

The purpose of this utility model is the domestic gas boiler that the Automatic Control that a kind of production cost is low, volume is little, heat transfer area is big, pollution-free, safe in utilization is provided at the deficiencies in the prior art.

The purpose of this utility model is achieved in that

Domestic gas boiler, include boiler shell, the burner hearth pipeline, inlet and outlet pipe lines and gas combustion apparatus, wherein between the shell body of boiler and inner housing, form a semi-enclosed annular attemperater, shell body is provided with independent water inlet pipe, outlet pipe and vapor outlet port, on the inwall of boiler inner housing, coil the annular furnace pipeline from bottom to top, the lower port of burner hearth pipeline communicates with water inlet pipe, the top of burner hearth pipeline is provided with heating water tank, heating water tank respectively with the upper port of burner hearth pipeline, outlet pipe is connected, the middle part of heating water tank has flue, communicate with the external world by attemperater and shell body, around the top of boiler jacket body and flue, be provided with miniature stove and accessory leg, gas combustion apparatus is installed in the bottom of boiler jacket body, micro pump is installed on water inlet pipe, water to heating system inside plays the forced circulation effect, and simultaneously, this device is provided with gas alarm system and TEMP electronic automatic control system.

The utlity model has following advantage:

1, owing to adopted the mode of pipe (annular furnace pipeline) case (heating water tank) combination to constitute boiler furnace, both reduced the furnace volume of quite a few, guaranteed the interior water amount of furnace tube of the boiler heating that heating area is required again, simultaneously, heating water tank has been sealed the top of burner hearth, the middle part only is provided with a flue, has therefore increased the heating surface area of burner hearth, has improved the thermal efficiency.

2, " machine " uses: the utility model can provide used hot water of shower and the drinking hot water in the attemperater in heating, in addition, also can utilize the waste heat at flue place, heats up water or makes coffee on miniature stove and accessory leg etc.

3, because of having adopted TEMP electronic automatic control device and air-sensitive warning system, therefore easy to operate, safe in utilization.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the structure chart of the utility model inner housing inside.

Fig. 3 is a fundamental diagram of the present utility model.

Fig. 4 is an electrical principle block diagram of the present utility model.

See figures.1.and.2, between the shell body (1) of boiler and inner housing (3), form the annular attemperater (2) of a sealing, shell body (1) is provided with independent water inlet pipe (10), outlet pipe (11) and vapor outlet port (9), on the inwall of boiler inner housing (3), coil annular furnace pipeline (4) from bottom to top, the lower port of burner hearth pipeline (4) communicates with water inlet pipe (5), the top of burner hearth pipeline (4) is provided with heating water tank (14), heating water tank (14) respectively with the upper port of annular furnace pipeline (4), outlet pipe (12) is connected, by boiler inner housing (3), burner hearth pipeline (4), heating water tank (14) has constituted boiler furnace, the top that heating water tank (14) has been sealed burner hearth, have a flue (8) in the middle, communicate with the external world by attemperater (2) and shell body (1), around the top of boiler jacket body (1) and flue (8), be provided with miniature stove and accessory leg (7), in its underpart support fixation, gas combustion apparatus (13) is installed in the bottom center place of shell body (1) to the integral body of boiler jacket body (1) by support (6).

With reference to Fig. 3, micro pump (15) is installed on water inlet pipe (5), its effect is that water inner in the heating system is carried out forced circulation.

Operation principle is with reference to Fig. 1, Fig. 2 and Fig. 3.

Running water in the water tank (16) enters in annular furnace pipeline (4) and the heating water tank (14) by water inlet pipe (5) and micro pump (15), gas heating through gas combustion apparatus (13), cold water becomes hot water, by outlet pipe (12) to radiator (17) and shower bath (18) hot-water supply, the water that loses heat energy is back in water inlet pipe (5) and the micro pump (15) through pipeline, and so forth, reach the heating purpose.Water in the attemperater (2) is replenished by water inlet pipe (10) supply, and boiler inner housing (3) is incubated, and the water of its heating is drinkable by outlet pipe (11).In addition, the waste heat that utilizes flue (8) to locate can be heated up water or make coffee on miniature stove and accessory leg etc.
