Description

Household miniature hot-water central heating arrangement

The utility model relates to a kind of heating device, particularly a kind of domestic hot water's heating device.

The present useful stove of warming oneself by a fire of family's winter heating, also useful fuel gas heating apparatus also has with space heater, the stove waste of fuel of warming oneself by a fire is big, seriously polluted, and corrosivity is big, use trouble, room air is bad and dust is big, and the fuel gas heating apparatus oxygen demand is big, and drying has flavor, the danger of poisoning is arranged, space heater power consumption is big, and the heating scope is little, and air is also dry.Now some big unit also has to adopt and concentrates the water-heating system heating, and its investment is big, and equipment is many, needs special messenger's burning boiler, and the radiator in each room is done thicklyer owing to need bear certain water pressure, the cost height, and installation and maintenance are also inconvenient.

The purpose of this utility model is exactly in order to address the above problem, and a kind of domestic miniature hot water heater is provided.

Technical solution of the present utility model:

A kind of domestic miniature hot water heater, it includes miniature body of heater 1 and radiator 2, the delivery port of miniature body of heater 1 is communicated with radiator 2 by pipeline 3, in it is characterized in that miniature body of heater 1 is served as reasons, outer wall 4, the toroidal cavity body of 5 sealings of forming, on the sealing toroidal cavity body sidewall, the lower end has delivery port 6 and water inlet 7, the upper surface of miniature body of heater 1 is provided with outlet flue 8, be used for being connected with chimney 9, this outlet flue is communicated with cavity between miniature body of heater 1 inwall 4, place burning things which may cause a fire disaster in the cavity lower end between the inwall 4, the cavity body first half between inwall 4 is horizontally arranged with heat extraction exchange pipe 10, the two ends of each heat-exchange tube 10 are respectively with interior, outer wall 4, sealing annular cavity body between 5 is communicated with, the outstanding radiation ball 11 of forming by metal tungsten wire that connects on the outer wall of a bottom heat-exchange tube 10, its hottest point of burning things which may cause a fire disaster in the cavity lower end between inwall 4, the cavity body Lower Half between inwall 4 is provided with vertical secondary ventilating ducting 12 along inwall 4 inner surfaces.

The utility model is simple in structure, and volume is little, and cost is low, and sanitation and hygiene are safe and reliable, and are easy to install, no waste gas non-corrosiveness, and power consumption is few, and heat is imitated high, and with the humid air, the heating scope is big, and hot water can be provided, and is multiple functional.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the structural representation of the miniature body of heater of the utility model.

As Fig. 1,2, the burning things which may cause a fire disaster that the cavity lower end between miniature body of heater 1 inwall 4 is provided with is preferably combustion gas, fuel oil burning things which may cause a fire disaster, and its kitchen range puts in inwall cavity lower end by burning things which may cause a fire disaster frame 14, also can adopt the burning things which may cause a fire disaster of other fuel.The delivery port 6 of miniature body of heater 1 can be communicated with the water inlet of two radiators 2 by pipeline 3, to be used for the heating in two rooms, also can connect boiler 15 simultaneously, for hot water, or the pouring shower nozzle is set on boiler 15 for bathing usefulness, the delivery port 7 of miniature body of heater 1 is communicated with the water source, is communicated with the delivery port of two radiators 2 simultaneously, constitutes hot water cyclesystem.The utility model fully takes into account conduction in selection, convection current, three factors of radiation, and the utility model is that the open temperature difference is circulating, then the requirement of strength to miniature body of heater 1 and heating installation body 2 is very low, so miniature body of heater 1 and radiator 2 all adopt the thin steel of the high low-carbon (LC) of thermal conductivity factor to make, reduce cost on the one hand greatly, handling ease, make the hot water cyclesystem operation very safe on the other hand, need not to use the circulating pump consumed power, like this, the heat that the utility model produces burning can be under less resistance to heat situation, be delivered to indoor by miniature body of heater 1 by radiator 2 through medium (water), because the outer surface of miniature body of heater 1 outer wall 5 is provided with one deck heat-insulation layer 13, has reduced the convection current radiation and conducted the heat that is discharged into the space simultaneously.The utility model since between miniature body of heater 1 inwall 4 the cavity body first half one heat extraction exchange pipe 10 is set, the burning contact area is increased greatly, the contact site is the most effective, is convenient to hot water and constantly flows therein and be heated.Because heat exchange is abundant, the EGT that miniature body of heater 1 upper surface outlet flue 8 is discharged by chimney 9 reduces.The utility model is owing to be provided with radiation ball 11 and secondary ventilating ducting 12, and secondary ventilating ducting 12 is provided with four, and they evenly are arranged on the Lower Half inner surface of inwall 4, so make burning more abundant.Combustion gas (fuel oil) fully mixes toroidal cavity body and the heat-exchange tube 10 that miniature body of heater 1 is heated in after-combustion with air, heat the medium (water) in it, radiation ball 11 with the burning things which may cause a fire disaster hottest point burns red simultaneously, send the air that come at first through burning things which may cause a fire disaster preheating obtain burn desired oxygen from secondary ventilating ducting 12 this moment, make the combustion gas of primary combustion heat mixing generation second-time burning once again, the heat release of fully burning of its remaining fuel gas, further add heat radiation ball 11 again, thereby further heat the sealing annular housing and the heat-exchange tube 10 of miniature body of heater 1, more heat is delivered to indoor.The utility model all is provided with ball valve on the water inlet pipe of each radiator 2, can choose at random the room or the control heating temperature of heating as required.Therefore burning things which may cause a fire disaster kitchen range of the present utility model can adopt electric ignition and the adjustable mode of tolerance, and random switch heating installation is regulated temperature and air consumption, is particularly suitable for nuclear family and uses, from the only need tens minutes of radiator heat production of lighting a fire.
