Description

Heating and cooking two-purpose hot-wind stove

The utility model relates to a kind of civilian hot-air heating cooking dual-purpose stove, belongs to the technical field of Civil energy-saving cooking stove.

Along with the raising of living standard of urban and rural population level, adopt heating stove in generally being in, and supply stove that sell or hot-water heating on the market, its cardinal principle is still traditional Industrial Boiler, adopts Natural Circulation.Though through many improvement, its major defect is that fuel is just lower with rate, because the low interior ignition temperature of stove that reduced of water temperature in the body of heater, fuel combustion is difficult for and is insufficient; The water that the user uses is all handled without softening and deoxygenation, very easily be subjected to corrosion and scaling in pipe-line system, even stop up, make the life-span of radiator short, especially when using stove, also to add and purchase stove and accessory, invest also bigger at indoor configuration radiator, though it is convenient but also uneconomical that some resident makes the stove of electricity consumption or coal gas use in addition, therefore presses for a kind of economical and practical stove.

The purpose of this utility model is that a kind of civilian hot-air heating cooking dual-purpose stove will be provided, and it can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, form a combustion chamber with insulation tile and internal layer body of heater, its top suitable for reading is that flue is equipped with triangle heat exchange fin and reverse combustion mouth, its effect is to carry out the burning second time, the pollution of flue dust is reduced, improve the thermal efficiency, flue stretches out, and a flue outlet is arranged, and the dual-purpose stove housing is lined with insulation material, blower fan and combustion-supporting gate valve are equipped with in its below, damper is housed out above the air channel, and combustion-supporting gate valve is closed when usual, and air quantity outflows from the air channel by going out damper, as improving burning velocity, just open combustion-supporting gate valve, make burning faster, the spirality guide vane is housed between the housing of stove and internal layer body of heater, and it forms air intake to turn back for three times and directly is blown in the stove again, do not need to add any servicing unit, just can be for the heating of multilayer inner room.

Fig. 1 is the schematic diagram of civilian hot blast heating-cooking dual-purpose stove

Now in conjunction with the accompanying drawings the structure of civilian hot blast heating-cooking dual-purpose stove is described in further detail.

By Fig. 1, constitute the combustion chamber (5) of garden tubular by insulation tile (4), combustion chamber (5) has loam cake (14) and end opening (15) to constitute an internal layer body of heater with internal layer body of heater (16), top in (14) suitable for reading, fire door and a flue join, flue extends to a side, bending is stretched away again, form a flue outlet (9), the cigarette dispatch thus of going out is just gone out, the top that triangle fin (6) triangle heat exchange fin (6) triangle heat exchange fin is housed in flue is reverse combustion mouth (8), and unburnt chemical fuel gas produces secondary combustion process through triangle heat exchange fin (6) and reverse after-flame mouth (8).Because the high heat of sufficient intake furnace wall, and the cooperation of triangle heat exchange fin (8) can fully finish the second-time burning effect, so the surplus cigarette of discharging from the flue outlet harmfulness of atmosphere pollution that has been the minimizing that purifies.Be lined with insulation material (2) in the dual-purpose stove housing (17), make the unlikely decline of temperature of flue (18), between housing (17) and internal layer shell (16), guide vane (3) is housed, it is arranged in a spirality along the internal layer furnace shell, housing (17) lower-left side has the below that an air inlet (13) blower fan (12) just places adiabator layer (2), (15) below of going to the bottom of (5) in the combustion chamber, combustion-supporting gate valve (11) is equipped with on the left side, the ash discharge gate valve is equipped with in housing (1) lower right side, its controlled ash amount of making, the upper left side of housing (17), damper (10) is housed out, upper stone or metal plate for standing on a stove as a precaution against fire (7) is positioned at the top of housing (17), and base (18) is positioned at the bottom of housing (17).

Air is heat exchange and combustion-supporting medium, is blasted from air inlet (12) by blower fan (12), and the heat exchange of circulating air process body of heater is returned windbreak after three times by guide vane, directly is blown into heating with indoor through going out damper (10) again.By the heat exchange of cold and hot air mass transfer, also can pass through single channel pipeline transmission hot-air for the room of multilayer inner room, at this moment do not need to add any additional heat transmission equipment yet, thereby subtracted one-time investment husky.

Lighting a fire or adjusting damper and combustion-supporting gate valve during cooking in order to improve burning velocity, part or all air quantity is blasted the combustion chamber improved burning, can take into account the sharing of load of regulating cooking and heating like this, also can control burning velocity on a large scale, accomplish that a wind uses more.Guiding fan blade (3) between internal layer body of heater and the shell has improved the heat exchange between air and stove, additional certain circulation resistance in the right body of heater.

Mutually two with prior art, this civil air heating-cooking dual-purpose stove has following advantage:

1, fire door be provided with the triangle heat exchange wing and oppositely combustion mouth make the fuel gas that does not burn produce second-time burning not only to improve the thermal efficiency but also reduced smoke-discharging pollution.

2, the guiding fan blade is housed between internal layer body of heater and the outer casing, has improved the heat exchange effect between body of heater, and additional certain circulation resistance.

3, can also make the air Natural Circulation reach underload heating without the blower fan forced circulation.

4, utilize out the combustion-supporting gate valve of damper can the part air quantity or all air quantity send into the combustion chamber and improved combustion efficiency, improve burning velocity.

Claims (2)

1, a kind of civilian hot-air heating cooking dual-purpose stove, it is characterized in that constituting garden cannular combustion chamber (5) by the insulation tile, it is made up of (14) suitable for reading end openings (15) internal layer bodies of heater (16) insulation tiles (4), its top fire door has flue, the hot fin of triangle (6) is housed in the flue, the top of triangle heat exchange fin (6) is reverse combustion mouth (8), flue stretches out, a flue outlet (9) is arranged, the dual-purpose stove housing is lined with insulation material in (17), and it is arranged in a spirality along the internal layer body of heater between housing (17) and the internal layer body of heater (16) guide vane (3) to be housed.

2, dual-purpose stove according to claim 1, it is characterized in that housing (17) lower-left side is air inlet (13), blower fan (12) places the below of insulation material, combustion-supporting gate valve (11) is equipped with on the left side, (15) below going to the bottom, ash discharge gate valve (1) is equipped with in housing (1) lower right side, and damper (10) is equipped with out on housing (17) upper left side.
