Description
Technical field
The present invention relates to kitchen range technical field, especially a kind of stir-fry stove 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 used, very large inconvenience is brought to the work of cook, 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, docked by upper cover 6 and base 8 and form, upper cover 6 and base 8 inside form mixing chamber 9, upper cover 6 crown center has through hole 2, mixing chamber 9 is positioned at built with a wind scooper 17 bottom upper cover 6, between bottom wind scooper 17 and upper cover 6, some pieces of doughnut-shaped steel plates 1 are housed, separated by packing ring 5 between doughnut-shaped steel plate 1 between two and be formed with annular outgassing groove 7, the diameter of the interior circular hole 3 of doughnut-shaped steel plate 1 is equal with the diameter of the through hole 2 in the middle of upper cover 6, combustion chamber 4 is formed between the interior circular hole 3 of through hole 2 and all doughnut-shaped steel plates 1.In the middle of the bottom of base 8, tube connector 11 is housed, connect 11 one end and to 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 is connected with tube connector 11, and the other end is provided with air inlet 12.Also be fitted with the gas inlet pipe 14 that is pointed to tube connector 11 in elbow 13, gas inlet pipe 14 offer a circle gas injection hole 15.During work, air is blasted by air inlet 12 by air blast, and enter wind scooper 17 by tube connector 11 after combustion gas and air mixing, then reverse flow flows out downwards through air guide hole 10, gaseous mixture flows out wind scooper 17 and enters mixing chamber 9, enters combustion chamber 4 burn finally by annular outgassing groove 7.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 due to mixing chamber 9 space less, cause real work effect still undesirable, fuel gas buring is still insufficient, more violent blue flame can not be kept always, the problem of most critical is that this burner does not have kindling material cap and is supplied to separately the high-purity gas of kindling material cap, the kindling material always do not lighted is used for igniting, this burner is caused not turn fire down, because the mixing chamber of this burner 9 not only limited space, and gaseous mixture just need can enter combustion chamber 4 through reverse refluence several times, gaseous mixture air pressure is original 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 will solve traditional burner cannot realize that combustion gas Thorough combustion, energy consumption are comparatively large, noise is comparatively large, easily produce the problem such as peppery eye or pungent peculiar smell, provides a kind of stir-fry stove premix hollow burner of not peppery eyes.
