Description

Indirect type domestic gas hot water heater

The utility model relates to a kind of heating device, particularly a kind of indirect type domestic gas hot water heater.

Family uses gas-heating to have cleaning, characteristics fast.In order to reach the purpose of fast starting with less load, indirect type domestic gas hot water heater's in the market combustion heat-exchange structure more complicated, burner mostly is the cast iron burner, not only heaviness but also be difficult for the designed combustion chamber; Many designs have fin or inserted sheet with augmentation of heat transfer in the flue, but cause processing difficulties, and cost increases; Existing in addition heating does not have safety device, in case accident extinguishing, combustion gas will leak into indoor, cause explosion accident.

In view of common indirect type domestic gas hot water heater has the problems referred to above; the purpose of this utility model is by changing the combustion heat-exchange system; be aided with flame-out protection device, design indirect type domestic gas hot water heater simple in structure, that starting is fast, efficient is high, pollution is little, safe and reliable.

A kind of indirect type domestic gas hot water heater; mainly form by burner, combustion chamber, remittance cigarette device, heating clamber, flame-out protection device, igniter, inlet tube and outlet tube, smoke exhaust pipe, shell, support etc.; it is characterized in that; heating clamber is shaped as inverted concave; the cigarette device that converges is placed on heating clamber inside; and by some smoke collection pipes and combustion chamber UNICOM, by smoke exhaust pipe flue gas is discharged, stainless steel punching press burner and flame-out protection device, igniter are positioned at the middle and lower part of groove combustion chamber.

The cigarette device that converges is a circulation structure in the rectangle, some smoke collection pipes be positioned at converge four medial surfaces of cigarette device wherein three sides and and the smoke exhaust pipe branch be located at the two ends of remittance cigarette device.

Running of the present utility model is: take fire after heating device whole system is filled with water, the high-temperature flue gas that burning discharges enters in the interior circulation remittance cigarette device that is immersed in the water by some smoke collection pipes in the combustion chamber, discharge from the smoke exhaust pipe of the remittance cigarette device other end then, temperature raises after the radiation and convection heat exchange of the water process outer wall of combustion chamber in the heating clamber and this heat exchange of convection current of remittance cigarette device, flow to the inlet of radiator from delivery port, to indoor heat radiation, the cooling back is back to heating from water inlet pipe and thinks highly of new heating through radiator.So move in circles, lean on hot water or cold water's density contrast to carry out Natural Circulation.

In the heating process of a few hours, in case wind or flue gas refluence are arranged and make burner flame-out, flame-out protection device moves immediately, at one minute internal cutting off source of the gas, avoids the danger of gas leakage.

The utility model adopts the interior circulation remittance cigarette device that is immersed in the water, makes processing simple, and cost reduces, and heat-exchange system only is half of existing heating heat-exchange system cost; Add and be equipped with stainless steel punching press burner and flame-out protection device; the thermal efficiency of this heating device is up to more than 85%; the discharge capacity of carbon monoxide only 0.01% in the flue gas; saved the energy greatly; alleviated environmental pollution, and igniting automatically, auto extinguishing; the function of Natural Circulation makes that this heating device is easy to use, safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is interior circulation remittance cigarette device sketches.

As shown in Figure 1; in the water that the cigarette device 12 that converges immerses in the inverted concave heating clamber 11; and by smoke collection pipe 9 and combustion chamber 10 UNICOMs; by smoke exhaust pipe 16 waste gas is discharged; stainless steel punching press burner 7 and flame-out protection device 6; pulse ignition device 5 stretches into 20-30mm in the combustion chamber 10 from the center; air inlet pipe 2; valve body assembly 4; arteries and veins igniter 5; flame-out protection device 6; burner 7; heating clamber 11 and shell 18 all are fixed on the support 1; loam cake 14 can freely be buckled on the shell 18; the thick heat-insulation layer of 40mm 13 is arranged, to reduce radiation loss between shell 18 and heating clamber 11.

Igniter 5 is the electronic impulse formula, is furnished with delay circuit, plays the purpose of lighting fast; 7 burnings of stainless steel punching press burner are complete, and adaptability is good; Flame-out protection device 6 is a thermoelectric (al) type; form by thermocouple, magnetic valve and executive circuit; thermocouple is heated and produces electromotive force magnetic valve is opened during burner 7 burning; make fuel gas pipeline unimpeded; in case accident extinguishing, thermocouple cooling back electromotive force disappears, and magnetic valve closes valve; cut off fuel gas path, prevent that combustion gas from leaking.

During whole heating system operate as normal, the flue gas of being discharged by smoke exhaust pipe 16 is discharged outdoor via the flue of 1-2 rice, guarantee the indoor cleaning health; Outlet pipe 8, water inlet pipe 17 link to each other with the advancing of radiator, return pipe respectively, constitute natural convection loop, and thermic load is designed to two retainings, and a retaining is 6KW, guarantees fast starting; When water temperature reaches the heating requirement in the whole heating system, can thermic load be adjusted to the second retaining 4KW by combustion gas knob 3, can guarantee that like this system normally moves, and has saved the energy again.

As shown in Figure 2, the cigarette device 12 that converges be interior circulation structure, and three smoke collection pipes 9 and smoke exhaust pipe were located at the two ends of remittance cigarette device in 16 minutes, guarantee that flue gas flows through remittance cigarette device whole process, be provided with drainpipe 15 in bottom, condensed water in the flue gas is in time discharged, be beneficial to heat exchange near the remittance cigarette device of smoke exhaust pipe.

The utility model can be adapted to liquefied petroleum gas, natural gas, artificial coal gas.
