Abstract
The invention provides a cooking and heating furnace with upper and lower gas ducts. The cooking and heating furnace comprises a panel and a furnace body, wherein a hearth is arranged in the furnace body; a grate is arranged in the hearth; a combustion chamber is arranged above the grate; a dust containing box is arranged below the grate; a feeding opening is arranged on the combustion chamber; the upper gas duct is arranged at the upper end of the combustion chamber; the combustion chamber is communicated with the upper gas duct; a heat storage and radiation box is arranged at the lower part of the dust containing box; the lower gas duct is arranged on the heat storage and radiation box; the heat storage and radiation box is communicated with the lower gas duct; the upper gas duct is communicated with the heat storage and radiation box through an interlayer of the furnace body; a switch is arranged on the upper gas duct; the upper gas duct is communicated with an external gas duct through the switch; and the lower gas duct is communicated with the external gas duct. The cooking and heating furnace provided by the invention has the advantages as follows: the upper gas duct and the lower gas duct are arranged, so that the gas ducts can be converted according to requirements. Therefore, not only can the smoke heat use ratio be improved to enable to light a fire more conveniently, but also the furnace is more convenient to use.
Description
Technical field
The present invention relates to a kind of civilian stove, particularly a kind ofly can arbitrarily change, have the cooking heating furnace of lower flue because of the cooking heating function is different.
Background technology
The existing stove smoke exhaust methods that adopt upper flue more; Can improve smoke exhaust efficiency like this, increase the firepower of stove, but be unfavorable for utilizing the heat of flue gas itself; If adopt the smoke exhaust method of the next flue; Though can the distance of flow of prolong smoke in stove improve the utilization rate of flue gas heat, the efficient that the fume exhausting type of upper/lower positions flue is lit a fire is low, the stove and accessory firepower of processing is little.
Summary of the invention
Technical problem to be solved by this invention provides a kind of utilization rate that both can improve the inner flue gas of the stove heat, can improve the efficient of lighting a fire again, the cooking heating dual-purpose stove that has lower flue that the cooking heating is dual-purpose.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: stove comprises panel, body of heater, is provided with burner hearth in the body of heater, is provided with fire grate in the burner hearth; The fire grate top is the combustion chamber, and the fire grate below is an ash box, and charging aperture is established in the combustion chamber; The upper end, combustion chamber is provided with upper flue, and the combustion chamber is communicated with upper flue, and the ash box bottom is provided with heat accumulation heat radiation case; Set flue on the heat accumulation heat radiation case, heat accumulation heat radiation case is communicated with lower flue, and upper flue is communicated with heat accumulation heat radiation case through the interlayer of body of heater; Upper flue is provided with switch, and upper flue is communicated with external flue through switch, and lower flue is communicated with external flue.
A kind of cooking heating furnace that has lower flue provided by the invention through respectively establishing a flue up and down at stove, is opened switch when lighting a fire; The discharging of flue gas stream nature; Let smoke pipe generate heat, it is strong to form negative pressure smoke pipe draft afterwards, can accomplish the cooking operation; Can not cause body of heater middle and lower part temperature too high, no longer need increase heat insulation facility in the body of heater yet.In the time of need increasing in the space temperature winter, close switch after lighting a fire, because of flue generates heat; Form negative pressure; Flue gas flows through external flue from lower flue naturally, need not ignite, combustion adjuvant and auxiliary air intake, has prolonged flue gas circulation distance; Make full use of the heat of flue gas itself, improved the utilization rate of cigarette heat.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In Fig. 1, stove comprises panel 1, body of heater 2, is provided with burner hearth 13 in the body of heater 2; Be provided with fire grate 5 in the burner hearth 13, fire grate 5 tops are combustion chamber 3, and fire grate 5 belows are ash box 4; Charging aperture 6 is established in combustion chamber 3, and 3 upper ends, combustion chamber are provided with upper flue 8, and combustion chamber 3 is communicated with upper flue 8; Ash box 4 bottoms are provided with heat accumulation heat radiation case 7, and heat accumulation heat radiation case 7 is communicated with lower flue 9, and upper flue 8 is communicated with heat accumulation heat radiation case 7 through the interlayer 10 of body of heater 2; Upper flue 8 is provided with switch 11, and said upper flue 8 is communicated with external flue 12 through switch 11, and lower flue 9 is communicated with external flue 12.
Operation principle of the present invention is following: when row is like cooking operations such as cookings at that time; Open switch 11; In combustion chamber 3, place fuel, the flue gas that fuel combustion produces gets into external flue 12 through upper flue 8 and discharges, and residual the entering in the ash box 4 through fire grate 5 of fuel deposited; When the operation of need warming oneself at cold weather; And make and break closes 11; Flue gas via interlayer 10 backs that stove and accessory produces get into heat accumulation heat radiation case 7, discharge through external flue 12 through the lower flue 9 that communicates with heat accumulation heat radiation case 7, have prolonged the emission path of flue gas in stove and accessory; Improved the utilization rate of heat, heating effect is good.
