Abstract
The utility model relates to a warm air furnace for domestic use, which belongs to the category of a hot air furnace. The warm air furnace for domestic use comprises a furnace body and a chimney and is characterized in that an air interlayer is arranged between an inner and an outer furnace bodies of the furnace body; cold air enters from the interlayer, thoroughly exchanges the heat with hot fume in the furnace body, and then becomes hot air with certain temperature to be released indoors after once more heat exchange with waste heat inside the chimney through a residual heat sleeve arranged outside the chimney. The utility model which has the advantages of low price, convenient operation, rapid hot reaction and high thermal efficiency is suitable for domestic warming or the dual-purpose use for warming and cooking and is especially for being used in humid areas with low temperature.
Description
The utility model is the dual-purpose civilian hot-blast stove of a kind of heat supply, cooking.
Existing civil heating stove all is to reach heating effect by the heat conduction of hot flue gas by pipeline or chimney, so fuel factor is slow, and chimney length limits by again in the room, and it is inconvenient to install, and the thermal efficiency is not high.
The purpose of this utility model is to design a kind of civilian hot-blast stove, and it can make the fuel factor of heating fast, thermal efficiency height, and transportation, simple installation.
The utility model is to realize like this, it enters air blanketing in the furnace main body with cold air, making itself and hot flue gas carry out after the sufficient heat exchange is hot-air, and with this hot-air once more in the air blanketing of chimney once more with directly be thrown into indoorly after the flue gas heat exchange, make indoor warm rapidly.This hot-blast stove fuel factor is fast, and no longer includes the heat conduction of pipeline (chimney), so thermal efficiency height adopts the plug-in structure with furnace main body and chimney in addition, so install, the equal facility very of transportation.
Below in conjunction with accompanying drawing structure of the present utility model is further specified.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 is the C-C cutaway view of Fig. 1.
By Fig. 1～4 as seen, this domestic burners comprises main body, chimney two parts, furnace main body is by external furnace body 19, inner furnace body 9, burner hearth 20, fire grate 6, fire door 7, ash chamber 10 is formed, it is characterized in that between external furnace body 19 and the inner furnace body 9 being a wind interlayer 21, its end is connected with the air inlet 1 of external furnace body 19 bottoms, the other end waste heat outer with being located at chimney overlaps 4 one ends and is connected, the other end of waste heat cover 4 is a hot-blast outlet, fire grate 6 has a combustion-supporting airduct 2 that is connected with air inlet 1, described inner furnace body 9 one ends are connected with chimney 14, its top is connected with fire door 18 with cooking a meal of external furnace body 19 by leading smoke pipe 23, cook a meal and be provided with bell 24 with fire door, the middle part of inner furnace body 9 is provided with a reducing 22, be provided with the logical fire hole 12 of a guiding flue gas stream between reducing 22 and inner furnace body 9 opposite sides, be provided with a wind isolation board 3 between reducing 22 tops and external furnace body, grey chamber 10, external furnace body 19, be respectively equipped with shoot door 10 on the air waste heat cover 4,11,16.
This hot-blast stove is when operate as normal, and coal is dropped on the inherent fire grate of stove by fire door 7 and burns, and better burning under the support of combustion-supporting airduct 2.Flue gas is risen by burner hearth 20, arrives upper of furnace body through the fire hole 12 of crossing at middle part, when opening with the bell 24 of fire door 18 when cooking a meal, chimney place door 25 is shut, combustion gas and hot flue gas mainly come out from fire door, can be used to the usefulness of cooking a meal, as the heating time spent, bell 24 is covered, open chimney door 25, flue gas merges in the bottom of chimney 14 at last from the diffluence backward along both sides of left and right two outlet flues 21, along with chimney rises, discharge outdoor.And cold wind enters wind interlayer in the stove from air inlet 1, with the high-temperature flue gas heat exchange of burner hearth, and rise to wind dividing plate 3 back and turn round by reducing 22 and be folded to again backward, at last in waste heat cover 4 with chimney in waste heat be thrown into after the heat exchange indoor once more.
Because after above-mentioned hot-blast stove air and flue gas carried out heat exchange fully, cold wind became hot blast very soon, and hot blast directly delivers to indoorly, so thermal efficiency height, thermal response is fast, and chimney and waste heat cover directly be connected with main furnace body, so very convenient during use.In order to improve the thermal efficiency and to make the stove internal combustion more abundant, this domestic burners can be offered twice aeration hole 8 on fire door 7, establish hot muscle 5 around inner furnace body outer wall and chimney outer wall, can in chimney, be provided with flight 15 in addition, so that flue gas flow rate is accelerated, the flue gas stroke prolongs, and makes heat exchange more abundant.
This hot-blast stove can add heat-insulation layer 17 at body of heater and waste heat wind cover 4 in order to improve the thermal efficiency in combustion system; Overheated in order to prevent burner hearth and other high temperature position metals, can weld bitch in advance thereon after, lay refractory protection 13 again, this protective layer can improve fire box temperature again and make furnace thermal efficiency higher simultaneously.
This stove can change the draft of chimney as the unlatching of heating, two time spent of cooking chimney door, shoot door in addition, thereby reaches the effect of control, adjusting cooking firepower.
This hot-blast stove also can increase hot air circulation and augmentation of heat transfer at the axial flow blower of the low blast of air intake vent 1 adapted, low noise, little power consumption.
