The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Figure 1-4, the present invention includes body of heater 1, described body of heater 1 top is provided with the air-supply passage 3 of air inlet, some fresh air inlets 9 are offered in air-supply passage 3 bottoms, on air-supply passage 3 inwalls, offer some secondary intake openings 8, one time fresh air inlet 9 is connected with burner hearth 2 bottoms with an air intake passage 10 between body of heater 1 by burner hearth 2 outer walls, air-supply passage 3 tops are provided with the annular flue 6 being connected with burner hearth 2, flue 6 is connected with burner hearth 2 by entering mouth, secondary intake opening 8 is directly connected with burner hearth 2 tops, some electrothermal modules 4 that utilize thermo-electric generation are set between flue 6 and air-supply passage 3.Referring to Fig. 5, between some electrothermal modules 4, there is space, in space, fill heat insulation layer 5, wherein, heat insulation layer 5 is the flexible material of thermal conductivity factor 0.01～0.2W/ (mK).Air inlet 13 is opened on air-supply passage 3 sidewalls, on air-supply passage 3 sidewalls, is also provided with the gas outlet being connected with air-supply passage 3, the adjacent setting of gas outlet and air inlet; Air inlet and enter mouth and be arranged at the same side, and air inlet 13 is arranged under mouth, be beneficial to and fully carry out heat exchange, air inlet place arranges the air blast of being powered and being driven by electrothermal module 4, and the air that discharge gas outlet is directly sent into indoor (or in tent).Between flue 6, electrothermal module 4, air-supply passage 3, adopt high-temperature plastic bonding (temperature that high-temperature plastic is at least resistance to 400 ℃).
A described fresh air inlet 9, the aperture of secondary intake opening 8 increase (the circumferencial direction aperture along air-supply passage increases gradually to gas outlet from air inlet in the aperture of fresh air inlet 9, secondary intake opening 8) gradually from air inlet to gas outlet, fresh air inlet and secondary intake opening gross area ratio are 8.0～10.0, can increase like this intake one time.Air in air-supply passage of the present invention enters air intake passage 10 one time by a fresh air inlet, passes through the further heat exchange with hearth outer wall from top to bottom, and temperature raises, and in burner hearth internal combustion fully and more stable, heat release rate is fast, and when reinforced, fire box temperature fluctuation is little; When in burner hearth, flue gas is through secondary intake opening, unburned flue gas burns again, and burner hearth and flue-gas temperature raise.
In the present invention, between flue 6 and air-supply passage 3, electrothermal module 4 is set, flue 6 enter that mouth is adjacent with exhaust opening to be arranged on flue 6 sidewalls, the flue gas that enters flue 6 from entering mouth, is discharged from exhaust opening 2 one weeks around burner hearth, and the exhaust opening place of flue 6 arranges chimney seat.In the present invention, flue was around burner hearth 2 one weeks, and flue gas is discharged around burner hearth in flue for 2 one weeks, has extended flue gas flow; Entering under mouth of the air inlet 13 of air-supply passage 3 and flue 6, between air-supply passage 3 and flue 6, heating surface area is large, makes full use of the heat of flue gas, and the air in air-supply passage 3 is heated soon, and air-supply heating speed is fast, and heat utilization efficiency is high.During use, because the flare of burner hearth 2 is flue 6 heating, the wind that air blast blows out enters the air-supply passage 3 of flue 6 bottoms, after the heat exchange with flue, become hot blast and through gas outlet, send into indoor (in tent), heat up rapidly in the space that makes to warm oneself, air blast, by electrothermal module 4 power supplies between flue 6 and air-supply passage 3, has improved heat utilization efficiency.Air-supply passage 3 and indoor radiation and the heat convection of carrying out, the wind pushing temperature of gas outlet decreases, and is conducive to the cooling of temperature-difference power generation module cold junction, has strengthened heat exchange simultaneously, and utilization efficiency of heat energy obviously improves, and heating effect is better.
Operation principle of the present invention is: between flue and air-supply passage, be provided with electrothermal module, the flue gas that hearth combustion produces is during through annular flue and electrothermal module and the air-supply passage heat exchange of downside, electrothermal module utilizes the temperature difference between flue and air-supply passage to produce the air-supply of driven by power air blast, air blast blasts the cold junction heat exchange of air and the electrothermal module of air-supply passage, heated air is sent into burner hearth for burning through sending into fresh air inlet, a secondary intake opening, fuel adds by charge door, guarantees the continuity of burning.
