Abstract

The utility model relates to a domestic gas boiler. A flue is in a bent shape. Heated water pipes and heat absorbing sheets which are vertically and horizontally arrayed are arranged in the flue and the combustion chamber. The upper part of a fume venting pipe is provided with an air reverse flowing preventing device. The utility model has the advantages of high heat energy use rate, small land occupation, simple structure, low cost, and safety. The utility model is suitable for heating in households in winter.

Description

Domestic gas boiler

The utility model is a kind of domestic gas boiler, belongs to normal-pressure boiler, is applicable to household heating.

More existing domestic gas boiler adopts and establishes the design that fireguard and pyrotechnics are walked pipe in the middle of the combustion chamber, and the heat part of fire is as adding hot water, and another part heat but directly contacts furnace wall and in-line arrangement air channel and scatters and disappears and consume, heat utilization efficiency is low, power consumption is high, adopts electronic air draft, has increased power consumption again.

The purpose of this utility model provides a kind of domestic gas boiler that improves heat utilization efficiency, reduction power consumption, prevents downdraught.

The purpose of this utility model is realized by following technical scheme:

A kind of domestic gas boiler, by boiler casing 3, heat-insulation layer 6, inwall 22, combustion chamber 18, burner 1, flue 13, be subjected to hot-water line 5, boiler water courage 4, outlet pipe 12, water tank 11, water inlet pipe 15, circulating pump 14, blowdown discharging valve 17, foot 16, fire hole 2, smoke exhaust pipe 8 is formed, its characteristics are: be provided with horn mouth 21 on smoke exhaust pipe 8, fixedly connected by dowel B20 between horn mouth 21 and the smoke exhaust pipe 8, be provided with the anti-wind tongue 9 of irritating in the middle of horn mouth 21 bottoms, the anti-wind tongue 9 of irritating is fixedly attached on the horn mouth 21 by dowel A19, horn mouth 21 tops are provided with manual blinker 10, flue 13 inside be provided with in length and breadth arrange have heat absorbing sheet 7 and connect boiler water courage 4 be subjected to hot-water line 5.

The utility model has the advantages that: simple in structure, cost is low, the heat utilization efficiency height, and it is little to consume energy, and can prevent downdraught, and simple to operate, safe and reliable, volume is little.Being fit to the average family independent heat supply uses.

The utility model is described in further detail to utilize the accompanying drawing illustrated embodiment below:

Fig. 1 is that cuing open of a kind of embodiment of the utility model shown structural representation.

Fig. 2 is the A-A cut-away view of Fig. 1.

Fig. 3 is the B-B cut-away view of Fig. 1.

Among the figure, 1 burner, 2 fire holes, 3 outer walls, 4 boiler water courages, 5 are subjected to hot-water line, 6 heat-insulation layers, 7 heat absorbing sheets, 8 smoke exhaust pipes, 9 anti-wind tongue, 10 manual blinkers, 11 water tanks of irritating, 12 outlet pipes, 13 flues, 14 circulating pumps, 15 water inlet pipes, 16 foots, 17 blowdown discharging valves, 18 combustion chambers, 19 dowel A, 20 dowel B, 21 horn mouths, 22 inwalls.

With reference to Fig. 1, Fig. 2, Fig. 3, I have implemented a kind of domestic gas boiler, and boiler integral body is vertical rectangle, and 4 foots 16 are established in the bottom, but belt wheel, convenient moving, burner 1 activity is positioned on 18 bottoms, combustion chamber, and convenient for maintaining uses natural gas, coal gas all can.Pass through fire hole 2 ignition combustion devices 1 with long tube gas ignitor, pyrotechnics rises along flue 13 circuitous states, prolonged heat exchanger time with boiler water courage 4, be subjected to hot-water line 5 and the heat absorbing sheet 7 arranged in length and breadth in combustion chamber and the flue are also surrounded by pyrotechnics simultaneously, carry out heat exchange with Guan Zhongshui, remaining heat is discharged through the preventing air reverse flow device by stove top smoke exhaust pipe 8, the preventing air reverse flow device by horn mouth 21, anti-irritate wind tongue 9, manually blinker 10, dowel A19, dowel B20 form, anti-filling wind tongue 9 Wei Yuan Cone body cavity structure.When firm igniting, outdoor cold air pours in down a chimney, and is prevented irritating the limit wall that wind tongue 9 keeps off horn mouth 21, can not enter flue by in-line arrangement smoke pipe 8; When flue heat got up, flue gas flow to outdoor by the preventing air reverse flow device automatically.When flame-out, rotation manual blinker 10 separates indoor-outdoor air.Between inwall 22 and outer wall 3, be provided with heat-insulation layer 6, make insulation in the stove.Be provided with water inlet pipe 15 and outlet pipe 12 in boiler one side,, do water filling and exhaust and use at outlet pipe 12 place's water receiving casees 11.Water inlet pipe 15 places add circulating pump 14, can connect many group radiators between circulating pump and the outlet pipe.Blowdown discharging valve 17 is connected on drop-bottom, for deposit in the anti-boiler water courage stops up.Because of artificial burner, every stove all is furnished with JBQ (T, R, Y)-K1 household gas leakage alarm that a Tai Taike Electric Applicance Co., Ltd produces, and can directly receive on smoke exhaust or the exhaust equipment.

Method of operating: burn the stokehold, at first boiler and radiator are filled with water, watching cistern water level should be at 2/3 place, next opens manual wind sheet, the igniter back of igniting is stretched in the stove on the stone or metal plate for standing a stove on as a precaution against fire from fire hole, open air valve point burner (note not using electronic lighter, ignite) simultaneously, treated 1 hour or the longer time with naked light, but indoor temperature reaches about 16 ℃ blowing outs of basic demand, room temperature can continue to rise, and radiator is incubated more than four hours, burns the stove time and can decide by floor space, burn every day and get final product for 2-3 time, can be by the principle of saving, cold can the burning, warm can the burning less more, to close manual wind sheet after the blowing out, to keep furnace temperature, preferably adorn air bleeding valve at the heating installation end, influence the water circulation in case deposit gas.

Points for attention:

Forbid anhydrous dry combustion method, when burning stove in the room not from the people, stove fire to be often observed,, gas valve be closed at once as finding the contingency accident extinguishing, after 30 minutes, determine stove internal memory gas all discharge outdoor after, can light a fire once more, in time find if fail, coal gas also can be discharged the outdoor danger of not having voluntarily by stove hall and flue, but notes not igniting at once.Burn stove time length and will consume a large amount of oxygen,, also can utilize door and window to stay certain slit or short time to open the door to replenish indoor oxygen, to guarantee safety so must leave little window in order to introducing outdoor fresh air.
