In order to solve the above technical problems, technical solution adopted in the utility model is: a kind of top-blown oil hot-water dress It sets, including furnace body, combustion chamber and burner, the burner is arranged in the opening at the top of furnace body inner combustion chamber；On furnace body Chimney is set on the shoulder of combustor side, lays heating tube in furnace body flue, the lower nozzle of heating tube and bottom of combustion chamber Smoke-box connection, the upper orifice of heating tube are connected to chimney；Medium water is full of between heating tube, along inboard wall of furnace body in medium water Circumference lays the coil pipe with entery and delivery port；The admitting pipe joint of furnace body is connect with external fluid delivery conduit pipeline.

Since the intracorporal water of furnace is reduced by thermal evaporation, for the intracorporal water of furnace is replenished in time, on the top of the furnace body If automatic water supply tank, automatic water supply tank is connect with external fluid delivery conduit, the water outlet of automatic water supply tank and the admitting pipe joint of furnace body Connection.

In order to ensure furnace body is using safe, overpressure safety device is also set in the upper top of the furnace body, on the top of furnace body It is connected with logical atmosphere pipe fitting, logical atmosphere pipe fitting is connect with automatic water supply tank pipeline.

The furnace body is vertical furnace, lays insulating layer between the furnace wall interlayer of furnace body, also sets furnace body in the lower part of furnace body Sewage pipe.

The utility model designed top-blown oil hot-water's device by adopting the above technical scheme, by existing fuel oil Boiler is improved, and burner is changed to the top for being located at boiler furnace, by blowing and spraying mist of oil downwards, in vertical combustor internal combustion It burns, expands the space of combustion chamber, increase the water heating surface (area) (HS of combustion chamber periphery；Smoke outlet is changed to the top for being located at boiler furnace Heating tube is located in flue by side, not only extends the distance that mist of oil is taken out of by flue gas, and resistance is directly taken out of when mist of oil, makes oil Mist full combustion, and the waste heat for also using flue gas in flue heats water, has saved energy, has improved the thermal efficiency；It is being situated between Coil pipe is laid along inboard wall of furnace body circumference in matter water, the water in coil pipe is heated by medium water, it is possible to provide endlessly hot water Source；The utility model burner, smoke outlet layout are in vertical boiler top side portion, and it is small that oil burning boiler occupies plane space, convenient for behaviour Make, repair and maintenance；Because being equipped with free vent (pipe fitting) at the top of furnace body, make to use in furnace body always in running without pressure Securely and reliably.The utility model expands the application range of oil burning boiler, can be applied on outdoor flow mobile shower bath and make well For its heating device.

Detailed description of the invention

Fig. 1 shows the structural schematic diagrams of the utility model top-blown oil hot-water's device；

Fig. 2 indicates the operation principle schematic diagram of the utility model top-blown oil hot-water's device.

Specific embodiment

The utility model top-blown oil hot-water's device is illustrated with reference to the accompanying drawing.

Referring to Fig. 1 and Fig. 2, the utility model top-blown oil hot-water device, including furnace body 1, combustion chamber 2 and burner 6, Wherein, furnace body 1 uses vertical furnace, and insulating layer 4 is built-in between the furnace wall interlayer of furnace body 1, and insulating layer 4 is the common heat preservation of filling Material covers with stainless steel plate 3 in the appearance of furnace body 1.Burner 6 is arranged in the opening at 1 inner combustion chamber of furnace body, 2 top.In furnace Chimney 8 is set on the shoulder of 2 side of combustion chamber on body 1.Heating tube 10 is laid in the flue of furnace body 1, under heating tube 10 Nozzle is connected to the smoke-box 12 of 2 bottom of combustion chamber, and the upper orifice of heating tube 10 is connected to chimney 8.It is full of between heating tube 10 Medium water lays the coil pipe 11 of tep reel water inlet tube connector 14, coil pipe water outlet connector 5 in medium water along the inner wall circumference of furnace body 1. The utility model is since the water in furnace body 1 is reduced by thermal evaporation, for the water being replenished in time in furnace body 1, on the top of furnace body 1 If automatic water supply tank 15, the installation site of automatic water supply tank 15 is higher than furnace body 1, and automatic water supply tank 15 is connected with external fluid delivery conduit It connects, the lower bottom part water outlet of automatic water supply tank 15 is connect with the admitting pipe joint 13 of furnace body 1.Furnace is additionally provided in the lower part of furnace body 1 Body sewage pipe.In order to ensure furnace body 1 is using safe, overpressure safety device 7 is also set in the upper top of furnace body 1, over-voltage fills safely Setting 7 can be safety air vavle, and the logical atmosphere pipe fitting 9 being connected to ambient atmosphere is connected on the top of furnace body 1, lead to atmosphere pipe fitting 9 It is connected with automatic water supply tank 15 by pipeline.

After the utility model starting, external fluid delivery conduit flows into automatic water supply tank 15 all the way, by the admitting pipe joint of furnace body 1 13 enter furnace body, stop water inlet after water in furnace body 1 fills.Start burner 6, burner 6 start by program dry, sparking, Oil spout, burning, the gas mixture that the spray head of burner 6 is sprayed, which enters, carries out full combustion in combustion chamber 2, after oil jetting combustion Generated hot-air successively passes through the lower part of smoke-box 12, heating tube 10, the top of smoke-box 12, to combustion chamber 2 and heating tube 10 Between medium water sufficiently heated.After the medium water in furnace body 1 be heated to setting temperature after, external fluid delivery conduit it is another Road water inlet flows into coil pipe 11 through coil pipe water supply connector 14, and after heating in coil pipe 11, the coil pipe water outlet connector 5 through coil pipe 11 flows out Hot water.Steam caused by water in furnace body 1 and pressure are by leading to atmosphere pipe fitting 9 into automatic water supply tank 15.In furnace body 1 Water when being reduced because of evaporation, automatic water supply tank 15 is kept in furnace body 1 automatically by the moisturizing into furnace body 1 of admitting pipe joint 13 Water in the altitude range of setting.The waste heat of burner 6 then passes through combustion tail gas through 8 row of chimney to atmosphere.
