Description

Multifunctional assembled domestic briquet stove

The utility model relates to a kind of combined household coal stove that has heating and toasting performance concurrently.

Existing multifunctional household coal stove is of a great variety, but is monolithic construction, and it mainly is made up of body of heater, tile, cyclic water jacket and baking vessel.As Chinese patent 2123017 disclosed domestic briquet stoves is exactly this structure.Existing this class coal stove is difficult to as required or changes of seasons is adjusted.For example, will give the water jacket water flowing period in non-heating in the same old way, otherwise very easily damage water jacket, this has just increased the unnecessary consumption of fuel.In addition, from the structure of water jacket, existing coal stove water jacket is essentially single tubular, and its heat-absorbent surface is less, is difficult to satisfy larger area heating requirement; From subsidiary baking vessel, existing coal stove only depends on burner hearth sidewall to conduct heat basically, and its effect is undesirable.

It is big and can load onto or shed the multifunctional assembled domestic briquet stove of cyclic water jacket as required easily that the purpose of this utility model provides a kind of heating load.

The solution that realizes the utility model purpose is: the multifunctional assembled domestic briquet stove that is provided comprises body of heater, tile, cyclic water jacket and baking vessel.This body of heater is made up of the upper furnace body and the lower furnace body that separate, and both are bound up with screw; The tertiary-air pipe that upper furnace body comprises the last tile, the flue around last tile, the chimney that communicates with this flue that are embedded with cage shape pan pipe, be positioned at the tile top and communicate with fire door around the cyclic water jacket of fire door and chimney and lower ending opening, upper end, wherein cage shape pan pipe is made up of the vertical tube that descends ring pipe and communicate with cyclic water jacket and following ring pipe, and cyclic water jacket and following ring pipe go out with the outside respectively, return pipe joins; Lower furnace body comprises lower stove lining, the secondary air channel, the baking vessel that communicate with air inlet and lower stove lining upper port and is embedded in the lower stove lining and stretches into hot grid in the baking vessel, the upper end open of secondary air channel wherein, and join with the lower port of upper furnace body tertiary-air pipe, the last end face of baking vessel contacts with the bottom surface of upper furnace body.Because upper and lower body of heater partable, and circulating water device all is located at upper furnace body, so, when non-heating is used period, upper furnace body can be shed, this moment, lower furnace body was just as common coal stove; When needing heating, upper and lower body of heater merges.The primary reformer that upper furnace body is set up watt is equivalent to lower stove lining is extended, so that further increase calory burning; The cage shape pan pipe of setting up increases heat exchange area widely, thereby has increased heating-surface.

Compared with prior art, whether easily the utility model can be according to heating loading, unloading recirculated water heater, thereby has avoided the unnecessary waste of fuel; Owing to improved the recirculated water heater, be provided with tertiary-air pipe in addition, make fuel be able to abundant burning, and improved leaving water temperature, thereby can enlarge area of heat-supply service.In addition, baking vessel of the present utility model is the multiaspect heat absorption, and is provided with hot grid, so indoor temperature is higher.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the cover plate figure supporting with lower furnace body shown in Figure 1, wherein numbers 25-pot circle.

Fig. 3 is the structure chart of the another kind of lower stove lining of the utility model.

As shown in Figure 1: going up the Lower Half that tile 2 is located at upper furnace body 1, is flue 3 around it.Cage shape pan pipe 4 is embedded in the tile 2, and it is by ring pipe 5 and vertical tube 6 are formed down.Flue gas is by fire door 7 approaching side flues 8, discharge by chimney 9 through flue 3 again, the cyclic water jacket 10 above in advancing, waste heat being passed to and below baking vessel 11.Recirculated water enters cage shape pan pipe 4 by return pipe 12 and is heated, and enters cyclic water jacket 10 then and is heated once more, is discharged by outlet pipe 13 at last.Be provided with ash output opening 14 in the bottom of flue 3.The right side of lower furnace body 15 is baking vessel 11, the palisade thing that hot grid 17 wherein are made up of a plurality of parallel bonding jumpers, its end is embedded in the wall of lower stove lining 18, thereby its temperature is higher, except that to baking vessel conducts heat, also be particularly suitable for toasting steamed bun or other food.The lower end of secondary air channel 19 communicates with inlet air plenum 20; The upper end is a three-way pipe 21, communicates with the burner hearth 22 of lower furnace body and the tertiary-air pipe 23 of upper furnace body respectively, and the fire door of upper furnace body is led in the upper end of tertiary-air pipe 23, and it is more abundant like this coal combustion to be got.Upper and lower body of heater is coupled as one with screw 24.During not heating, upper furnace body can be shed, then cover plate 16 (as shown in Figure 2) be covered on lower furnace body, promptly can be used as common coal stove and use.

In order to use diffusing coal, this coal stove can adopt inversed taper platform shape lower stove lining 31 shown in Figure 3, and it is made with die for special purpose, is provided with secondary air channel 32 in its sidewall, the wind hole 34 that there is secondary air hole 33 on the top and communicates with the tertiary-air pipe 23 of last tile 2.Lower stove lining 31 is placed on the fire-grating seat 35, and the fire bars 37 of fire grate 36 middle bodies is a moving grate.If will use honeycomb briquette the time, can put into the coal grid 38 with the corresponding bore of honeycomb briquette, the moving grate 36 of taking out middle body gets final product.
