Abstract
The utility model relates to a closed energy-saving burner which belongs to a cooking stove, comprising a cylinder body 4 whose upper and lower sides are respectively provided with a top cover 8 and an adjusting air door 11, a container 3 whose upper end is arranged in the cylinder body 4 via a contact surface of the cylinder body 4, a burning chamber 1 and a flue gas chamber 2. In the cylinder body 4, the burning chamber 1 and the flue gas chamber 2 are respectively formed between the bottom of the cylinder body 4 and the bottom of the container 3, and between the inner wall of the cylinder body 4 and the outer wall of the container 3. The utility model has the advantages that the open fire can not generate outside the burner in the burning process, the thermal efficiency is high, and the utility model can be used in some special occasions where the open fire is forbidden.
Description
The utility model relates to a kind of closed energy-saving burner, belongs to cooking stove.
Burners in prior.Because it is outside naked that hot spots reveals, when the pot body being positioned over the pillar upper end that is located on the burner base and lighting the fuel tank that is placed on burner base central authorities when having a dinner, not only cause heat waste, and safety inadequately, thereby can not use in the specific occasion of some no open flames.
The purpose of this utility model is will provide a kind of out-of-bounds can not produce naked light, closed energy-saving burner that the thermal efficiency is high in when burning at burner.
The purpose of this utility model is achieved like this: a kind of closed energy-saving burner, it comprise the upper and lower cylindrical shell 4 that has top cover 8 and damper 11 respectively, upper end by with container 3 in contacting of cylindrical shell 4 is located at cylindrical shell 4 and in cylindrical shell 4 respectively by formed combustion chamber 1 and smoke chamber 2 between cylindrical shell 4 bottoms and container 3 bottoms and between cylindrical shell 4 inwalls and container 3 outer walls.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is a structural representation of the present utility model.
The inboard of cylindrical shell 4 of the present utility model scribbles thermal insulation fire-resistant material 5, with the transmission loss of the heat energy of minimizing in combustion process, thereby improves the thermal efficiency.Cylindrical shell 4 can adopt plastics or metal material to make, and has damper 11 in the bottom of cylindrical shell 4 sidewalls, and the flame size when burning in order to be adjusted in is stopped working until closing damper 11.Rock for avoiding container 3 in cylindrical shell 4, to produce, inner bottom part rivet clasp at cylindrical shell 4 has fuel rack 10, thereby the bottom that makes container 3 rests on the fuel rack 10, on fuel rack 10, can place convenient solid fuel 9, also convenient solid fuel 9 can be placed directly in cylindrical shell 4 inner bottom parts, smokeless, ashless, nontoxic, free of contamination siliceous composite solid fuel (Chinese invention patent application number 93110568.4) when convenient solid fuel 9 preferably adopts burning, the top of cylindrical shell 4 is furnished with top cover 8, and periphery has the smoke evacuation pore 7 that communicates with smoke chamber 2.
The outer wall of container 3 of the present utility model is provided with spiral winding 6, plays enhanced heat transfer component therefrom.When the smoke evacuation pore 7 of the hot flue gas in the smoke chamber 2 on top cover 8 effluxes, owing to the effect of spiral winding 6 makes hot flue gas become the rising of spiraling.Because spiral winding 6 has destroyed the boundary layer of container wall, make the Laminar Flow of wall be converted into Turbulence Flow, thereby reduce thermal resistance, improved the thermal efficiency.The top of container 3 is processed with a flange 12, have on the flange 12 with top cover 8 on the smoke evacuation pore 13 that matches of smoke evacuation pore 7, flue gas in the smoke chamber 2 is discharged by the smoke evacuation pore 7 of smoke evacuation pore 13 on top cover 8, entire container 3 is that the flange 12 by its upper end is located in the cylindrical shell 4, and the bottom of container 3 is just in time rested on the fuel rack 10.Open damper 11, light the convenient solid fuel 9 that is placed on the fuel rack 10, the high-temperature flue gas that is produced when at this moment just burn abrim in the position of combustion chamber 1, these high-temperature flue gas are discharged through smoke chamber 2 and by smoke evacuation pore 13,7.Thereby finish the heating to container 3, whole heating process mainly is to give container 3 in the mode of radiation and convection heat transfer' heat-transfer by convection with thermal energy transfer.Whole in addition combustion process has been avoided the dew fire burns, so fool proof.
The utility model is located in the enclosed cylindrical shell 4, so fool proof combustion chamber 1, smoke chamber 2, container 3 owing to adopted said structure; Owing to be respectively equipped with thermal insulation fire-resistant material 5 and spiral winding 6 at the inwall of cylindrical shell 4 and the outer wall of container 3,, saved fuel so improved the thermal effect that adds to container 3.
Claims (3)
