Abstract

The utility model relates to a multifunctional cooking and warming stove. An annular hot air exchanger is assembled in a burning stove, and thus, the cold air can be heated to rise by the residual heat recovery of the fume, which realizes the purpose of hot air heating and meal cooking. The structure is that the periphery of the stove tile of a hearth is provided with the annular hot air exchanger whose top and bottom are provided with a cold inlet and a hot inlet, and a secondary air inlet pipe is assembled on a stove body, which improves the combustion efficiency. The utility model has the advantages of high combustion efficiency, clean and sanitary and convenient hot air heating. The utility model serves many purposes, such as cooking and heating.

Description

Multifunctional cooking and warming stove

The utility model relates to a kind of home-use cooking heating furnace tool, and outstanding finger is used cooking heating coal furnace more.

In background technology, the common traditional stove and accessory of selling on the market that an air feed of fire door is arranged of cooking and heating furnace adopts hot-water heating; The modified stove and accessory of the employing secondary air feed that has adopts fire door that the heating of hot-water heating pipe is arranged; The old-fashioned burner of still employing that has, the radiant heating of employing chimney and body of heater.In the above-mentioned technology, adopt hot-water heating, though high and other advantage of heating efficient is arranged, radiator occupation of land side is arranged, stove, pipeline and radiator often seep water and leak, inconvenient maintenance after using a period of time.Though and the chimney heating is convenient, indoor not too health, coal gas during the evening of not doing a good job is easy, threat to life.

The purpose of this utility model is the weak point that overcomes in the above-mentioned background technology, provide a kind of many with cooking heating coal furnace, utilize secondary air feed efficient combustion, flue gas waste heat recovery apparatus is set, make full use of fume afterheat and improve the thermal efficiency, utilize hot blast heating, the upper of furnace body cooking of still can cooking, reach the purpose that effectively utilizes the combustion heat.

Technical solution of the present utility model is as follows:

Body of heater comprises on the fire grate 14 that assembles in the furnace shell 13 tile 10, fire grate 14 times is by an air-inlet cavity 17 of being made up of the

airduct

15 and 13 ends of furnace shell, tile 10 peripheries are provided with secondary air channel 8, its main feature is the annular hot blast interchanger 6 of airduct 8 peripheries assembling sealing, its underpart assembling cold wind import 11, top assembling hot-blast outlet 18, back welding connects flue gas waste heat recovery pipe 7 up and down in hot blast interchanger 6, the top in fired coal combustion chamber in the logical tile 10 on the recovery tube 7, the down logical chimney 5 that puts a chimney on the stove and make the fire draw.

Technical solution of the present utility model also comprises:

Stationary annular spiral heat dissipation sheet 19 in hot blast interchanger 6.

Description of drawings of the present utility model is as follows:

Fig. 1 partly cuts open structural representation, also is the echelon sectional view of Fig. 2.

Fig. 2 is the vertical view after Fig. 1 removes bell 1.

Above-mentioned number in the figure is described as follows:

The 1-bell, the 2-pallet cover, the 3-furnace tray, 4-assists smoke exhaust pipe, the 5-chimney, 6-hot blast interchanger, 7-flue gas waste heat recovery pipe, 8-secondary air channel, the 9-heat-insulation layer, the 10-tile, the import of 11-cold wind, the 12-flue gas confluxes, the 13-furnace shell, 14-fire grate, airduct of 15-, 16-air inlet valve, air-inlet cavity of 17-, 18-hot-blast outlet, 19-spiral heat dissipation sheet, the 20-base, 21-strengthening band, 22-flue gas shunting road.

Be that the utility model is described in further detail accompanying drawing below: referring to Fig. 1, bottom fixed grate 14 in the furnace shell 13, annular tile 10 of assembling and secondary air channel 8 on the fire grate 14, secondary air channel 8 uniform 6, assembling heat-insulation layer 9 between secondary air channel 8 and tile 10, the material of heat-insulation layer 9 can be selected asbestos fibre or stone etc. for use, assembling hot blast interchanger 6 between secondary air channel 8 and furnace shell 13, uniform 6～12 the flue gas waste heat recovery pipes 7 of bottom annular up and down of annular hot blast interchanger 6, go up the flue gas shunting road 22 of top, logical fired coal combustion chamber, the flue gas of logical chimney 5 bottoms confluxes 12 down, welding spiral heat dissipation sheet 19 in its hot blast interchanger 6, interchanger 6 tops are welded with hot-blast outlet 18, and the bottom is welded with cold wind import 11, filled heat insulating material between interchanger 6 and the furnace shell 13, as heat-insulation layer 9, chimney 5 stretches out from furnace shell 13 middle and lower parts, extends upward, top one side connects the auxiliary smoke exhaust pipe 4 that communicates, combustion-supporting effect when playing cooking.Furnace shell 13 bottoms, an air-inlet cavity 17 is formed in airduct 15 and furnace shell 13 bottoms, adjusts intake and carries out whole body of heater with 16 rotations of air inlet valve and be bearing on the base 20.In upper of furnace body, place annular furnace pallet 3, as the supporting cooker usefulness of cooking, put pallet cover 2 on the furnace tray 3, be used to bank up a fire or warm oneself, the body of heater top is fixing with strengthening band 21, the removable bell 1 of assembling on the strengthening band 21.

Whole operation principle is like this, coal-fired in tile 10 internal combustion as burner hearth, the top piles combustion chamber and can be used for cooking, air intake enters from an airduct 15, wherein to enter burner hearth combustion-supporting for most air quantity, and the sub-fraction air quantity rises and is preheated to the stove fire mouth along secondary pipe 8, and it is combustion-supporting to carry out secondary, fully burning improves efficiency of combustion.The flue gas of burner hearth top is under the sealing of bell 1 and pallet cover 2 or cooker, can only be from top to bottom along hot blast interchanger 6, arrange to atmosphere through chimney 5, the air in hot blast interchanger 6 spaces is under the transmission heat effect of flue gas and burner hearth, be heated and move upward, discharge from hot-blast outlet 18, to indoor heating wind, cold mouthful of import 11 of hot blast interchanger 6 bottoms, constantly with the cold air inspiration, form free convection, the fin 18 in the interchanger 6 is shape in the shape of a spiral, both strengthen heat-transfer effect, be beneficial to the hot blast circulation again.

Advantage of the present utility model and effect are as follows:

1, owing to the employing hot-wind heating, thus easily leaking, easily seeping water of hot-water heating existence avoided, and the shortcoming that takes up space, and with low cost.

2, owing to adopt the burner hearth periphery to exchange hot blast, so the burner hearth top still can be used for doing the meal cooking, reach the purpose of multi-use.

3, because the hot blast that adopts is to transmit the heat heating, thus this hot-wind heating avoided old-fashioned stove heating bring air stale, easily in the shortcoming of coal gas, and health, clean, energy-conservation, hot-wind heated efficient height, good flowing properties.

4, for the space of improving heating and heating temperature, can be under fire coal burns cmpletely, small blast fan of cold wind import 11 places assembling, hot-blast outlet 18 usefulness linking steel tubes through bull in parallel to several indoor hot blasts of supplying simultaneously.

5, simple in structure, operating maintenance is convenient, and cost is low, and it is little to take up an area of volume, easily promotes at average family.
