Description
Technical field
The present invention relates to kitchen range technical field, especially a kind of stir-fry kitchen range premix hollow burner of not peppery eyes.
Background technology
At present, burner on market easily produces peppery eye or pungent peculiar smell in the process of using, brought very large inconvenience to cook's work, for this reason, someone specialized designs has gone out a new burner, the structure of this traditional burner as depicted in figs. 1 and 2, by upper cover 6 and base 8 docking, formed, the inner mixing chamber 9 that forms of upper cover 6 and base 8, upper cover 6 crown centers have through hole 2, upper cover 6 bottoms are positioned at mixing chamber 9 wind scooper 17 are housed, between wind scooper 17 and upper cover 6 bottoms, some doughnut-shaped steel plates 1 are housed, between doughnut-shaped steel plate 1, by packing ring 5, separate between two and be formed with annular outgassing groove 7, the diameter of the through hole 2 that the diameter of the interior circular hole 3 of doughnut-shaped steel plate 1 is middle with upper cover 6 equates, between through hole 2 and the interior circular hole 3 of all doughnut-shaped steel plate 1, form combustion chamber 4.Tube connector 11 is housed in the middle of the bottom of base 8, connects 11 one end and put in wind scooper 17 and whirlwind deflector 16 is housed, the neighboring of whirlwind deflector 16 has a circle air guide hole 10; The other end protuberate basic unit 8 of tube connector 11 is also equipped with an elbow 13, and elbow 13 one end are connected with tube connector 11, and the other end is provided with air inlet 12.In elbow 13, be also fitted with a gas inlet pipe 14 that points to tube connector 11, on gas inlet pipe 14, offer a circle gas injection hole 15.During work, air blast is blasted air by air inlet 12, combustion gas and air enter wind scooper 17 by tube connector 11 after mixing, and then reverse flow flows out downwards through air guide hole 10, gaseous mixture flows out wind scooper 17 and enters mixing chamber 9, finally by annular outgassing groove 7, enters combustion chamber 4 burnings.Although the burner of this structure can prevent peppery eye or pungent peculiar smell, but noise is very large in the process of work, and because mixing chamber 9 spaces are less, cause real work effect still undesirable, fuel gas buring is still insufficient, can not keep more violent blue flame always, the problem of most critical is that this burner does not have kindling material cap and offers separately the high-purity gas of kindling material cap, the kindling material of always not lighting is used for igniting, cause this burner can not turn fire down, because the mixing chamber of this burner 9 is limited space not only, and gaseous mixture need just can enter combustion chamber 4 through reverse refluence several times, gaseous mixture air pressure is originally less, once turn air pressure down, will the missing of ignition or flame-out phenomenon of origination point.
Summary of the invention
Object of the present invention is exactly to solve that traditional burner cannot realize that combustion gas is fully burnt, energy consumption is large, noise more greatly, easily produces peppery eye or the pungent problems such as peculiar smell, and a kind of stir-fry kitchen range premix hollow burner of not peppery eyes is provided.
Concrete scheme of the present invention is: a kind of stir-fry kitchen range premix hollow burner of not peppery eyes, there is furnace shell, and on the lower sides of furnace shell, blast pipe is housed, on blast pipe, be fitted with gas inlet pipe; The crown center of furnace shell is equipped with stove dish, has the outer main fire hole of a circle on stove dish, and the top sides of furnace shell is along the upper cover of pushing down stove dish is housed; It is characterized in that: described stove dish is designed to upper, middle and lower-ranking hierarchic structure, and the diameter of upper strata, middle level, lower floor from top to bottom increases successively, upper cover is pressed in the top, outer ring of the lower floor of stove dish, its main fire hole in China and foreign countries is arranged in the junction of the outer ring on upper strata and the outer ring in middle level, between the outer ring in middle level and upper cover, be formed with outer air drain, the junction of the outer ring in middle level and the outer ring of lower floor has the external compensation fire hole of the outward-dipping layout of a circle, and the outlet of external compensation fire hole is arranged over against outer air drain; Insulating collar is equipped with in the centre of stove dish, and a natural induced draft pipe is equipped with in the bottom of insulating collar, and furnace shell is stretched out in the bottom of natural induced draft pipe; In described furnace shell, be positioned at natural induced draft pipe outside wind deflector is housed, on wind deflector, have a circle air guide hole, a mixing cover is equipped with at the top of wind deflector, this mixing cover is comprised of the choke circle at cover body and cover body top, the top of choke circle is horn mouth shape, between choke circle and natural induced draft pipe outer wall, is formed with air channel.
The inner ring on upper strata of the dish of stove described in the present invention and the junction of the inner ring in middle level have a circle inner main fire hole, air drain in forming between the inner ring in the middle level of stove dish and insulating collar, the junction of the inner ring in the middle level of stove dish and the inner ring of lower floor has the interior compensation fire hole of inside oblique layout, and the outlet of interior compensation fire hole is arranged over against interior air drain.
Outer all outward-dipping settings of main fire hole described in the present invention, its angle of inclination is 6 °～10 °; The setting that all slopes inwardly of described inner main fire hole, its angle of inclination is 12 °～18 °.
The angle of inclination of the fire hole of external compensation described in the present invention is 60 °～64 °, and the angle of inclination of interior compensation fire hole is 54 °～60 °.
In order to prevent that kindling material from being gone out by wind, the present invention has in the top of furnace shell one side the chamber of keeping out the wind, and indoor kindling material, ignition electrode, the flame-out pin of being fitted with keeps out the wind.
In order to facilitate burner of the present invention to be buckled on burner hearth, the present invention is also provided with the buckle of downward layout in the top of furnace shell one side.
