Abstract

The utility model relates to an efficient energy-saving firewood-burning stove. Structurally, a heat flow chamber is composed of an inner sleeve and an outer sleeve. In a combustion processes, when flame and temperature reaches a limit, heat flow flows in the closed heat insulation chamber through a control pipe and generates heat expansion. The efficient energy-saving firewood-burning stove has the advantages of quick ignited speed, high fire heat, large heating area and high heat efficiency, and can be automatically regulated according to needed temperature.

Description

Energy-efficient faggot stove

The utility model relates to cooking stove, relates to a kind of energy-efficient faggot stove in more detail, is specially adapted to family, restaurant, middle grill room.

Coal stove or faggot stove just at present commonly used, though can a stove multipotency, can carry out cooking, steamed rice, hot water simultaneously, as the stove main body, the speed of getting angry is slower, can not regulate automatically when being subjected to heat request when the height of flare and thickness surpass.

The purpose of this utility model is that providing a kind of to the public can overcome above-mentioned shortcoming, when burning but that wastes with present gas burner gas-fired aspect the firepower size, quick combustion, the intensity of a fire is prosperous, and heating surface area is big, thermal efficiency height, simultaneously can do even heating, after tableware leaves burning things which may cause a fire disaster, still can use the waste heat boiling, structurally form a hot-fluid storehouse by inside and outside two-layer cover, tableware and internal layer cover is heated simultaneously and is incubated and uses overcoat during heating, and the big I of firepower is regulated as required at any time.

Structural principle of the present utility model and details thereof provide from Figure of description and embodiment.

Fig. 1 is the novel structural principle cut-away view of this reality;

Fig. 2 is the novel door structure schematic diagram of this reality;

Further specify structural principle of the present utility model below in conjunction with Figure of description, it is to be welded with sheet iron that this reality wins novel monnolithic case.Top is divided into 2/5 spherical structure, the bottom is a column construction, body of heater the 1. layer with the 2. in the middle of the arc heat-insulation layer (6) and intermediate thermal insulating layer (10) be filled with aluminum silicate insulation material, upper furnace is divided into garden arc plate (3) in three layers, middle garden arc plate (4) and outer garden arc plate (5), 12 thermistor(-ter)s (2), pot keeps off river (1) and chimney (14) solder joint; The 2. layer be to store the hot-fluid storehouse in the middle of the layer arc 3. with the, when combustion process moderate heat merit and temperature acquire a certain degree, then type of thermal communication is crossed in the airtight adiabatic storehouse of thermistor(-ter) (2) inflow, impel the hot-fluid storehouse to produce thermal expansion, at this moment the firepower size is regulated thermal switch (7) as required, this moment, the hot-fluid in hot-fluid storehouse flowed into 4 convection current negative pressure airducts (9) rapidly, because convection current negative pressure airduct (9) is adiabatic heat-insulation all around, under thermodynamic activity, hot-fluid is until fire door control panel (12), control panel is under the effect of geometry, thereby the form of impelling hot-fluid to be converted to turbulent flow is delivered to left and right sides fire door (11).Left and right sides fire door is drilled with respectively like tiltedly towards 15 ° of angle apertures of axis direction, like this since turbulent flow reached the growth encourage combustion, the speed of getting angry is fast, and is intimately prosperous; And combustion chamber (8) can be controlled the diffusion of hot-fluid around the coal that is burning, in whole heat flow system, because heat energy constantly increases, pot retaining river (1) is parts that change with pot shape contact edge, fasten the contact edge of pot tightly, do not allow heat energy lose from contact edge, make whole hot-fluid form the integral body of an insulated enclosure like this, heat energy constantly increases, at this moment the hot-fluid storehouse of hot arc plate (3) and middle garden arc plate (4) in hot-fluid can only enter by thermistor(-ter) (2) again, impel the pressure of hot-fluid increasing, because chimney (14) welds together with the hot-fluid storehouse, at this moment the portion of hot flowing pressure is want to run away from chimney, but because there is an atmospheric existence outside of chimney, the thermal expansion that it is inner and the formation of pressure reduction impel whole interior heat to produce the pressure reduction of malleation and negative pressure, and whole hot-fluid has formed vacuum.Produce 5-7 torr negative pressure in the stove.Garden arc plate (3) is to make according to geometry in the stove, increase the heating surface area of pot, reach and evenly add heat request, left and right sides fire door (11) is fixed on down on the hearth box dividing plate, by about be divided into two, the inside one circle φ 5 is uniform, four φ 3 of aperture, totally 13 circles increase by a loop diameter outward and increase 10 millimeters φ 15, centerline diameter to the last φ of 13 circles 3 holes should be 125 millimeters, aperture becomes plum blossom Pu, and each φ 3 aperture is oblique 15 ° of angles towards the center, directly supply with the burning of fuel, hot-fluid in the whole stove circulates, and the speed of getting angry is fast; As long as, the ash that has burnt will be fallen on the closing cap fixed base plate (13), take out base plate (13) and can finish whole actions of buing or get by illegal means faggot when adding faggot by the control crank action.

Claims (3)

1, a kind of energy-efficient faggot stove, it is characterized in that upper of furnace body is 2/5 spherical structure, upper furnace is garden arc plate (3) in three layers, middle garden arc plate (4) and outer garden arc plate (5), thermistor(-ter) (2), a pot retaining river (1) are connected with chimney (14), body of heater the 1. layer 7. the middle heat-insulation layer (6) of layer arc and intermediate thermal insulating layer (10) are filled with silicic acid companion insulation material with the;

2, energy-efficient faggot stove according to claim 1 is characterized in that 3. 7. body of heater the pacifying 4 convection current negative pressure airducts (9), thermal switch (7), fire door control panel (12) in the layer arc intermediate storage hot-fluid storehouse with the;

3, effect energy-saving firewood stove according to claim 1, it is characterized in that left and right sides fire door (1) is fixed on down the hearth box dividing plate, septulum φ 3～φ 15 is totally 13 circles, whenever increase by a loop diameter outward and increase 10 millimeters, 125 millimeters of φ 3～φ 15 central diameter, each φ 3 aperture is oblique 15 ° of angles towards the center, and it is quincunx that aperture becomes.
