Door spring and nozzle.Problems be present when being used in inlaid gas range in the burner：One be due to burner be arranged on it is embedding
Enter in formula gas kitchen ranges, mixed once air comes from the kitchen range top, so the kitchen range top need to reserve air intlet, causes U.S. to the kitchen range top
See and structure causes to damage, otherwise can be because of lack of air, premix is insufficient, causes fuel gas buring incomplete.Second, burner burns
When operating mode is undesirable, user need to make house calls by the whole table cooker tool ability damper of lifting, or by factory repair personnel,
It is inconvenient.Third, when burner produces tempering, user can not be had found in time, and kitchen range are produced and greatly destroyed, or even are therefore sent out
Light a fire the major accidents such as calamity, blast, cause personal injury and property loss, when panel is glass material, easily produce glass
Blast.Fourth, the heat of burner is directly emitted in kitchen range, cause other part accelerated ageings and damage in kitchen range.
Above mentioned problem, Chinese patent notification number existing for lower air intake burner are used in order to solve inlaid gas range
CN205782941U discloses a kind of multi-functional direct injection upper air inlet burner, including the burner body and nozzle being connected with combustion gas,
Nozzle is provided with the blast tube being connected with combustion gas, and burner body is circle, nozzle be respectively arranged at the burner the center of circle and
On radius and form three kinds of inner ring nozzle, middle ring nozzle, outer shroud nozzle circulating type nozzle arrangements；It is inner ring nozzle, middle ring nozzle, outer
Ring spray mouth is respectively arranged with blast tube；The inner ring nozzle, middle ring nozzle, outer shroud nozzle are respectively arranged with steady fire cover.The knot
Although there is problems with structure without separately setting air admission hole in kitchen range bottom or cabinet：One is due to that installing space is limited, people
Main fiery admission line and air feeding in center pipeline can only be shortened, primary air is insufficient with combustion gas mixing, causes fuel gas buring endless
Entirely, fuel gas buring efficiency is low.Second, flame size only has large, medium and small three kinds of flame, the requirement of user can not be met.For
This, many scientific research institutions, manufacturer and knowledgeable people are researched and developed regarding to the issue above, but so far there has been no compared with
Rational product emerges.
The content of the invention
To overcome above mentioned problem existing for present upper air inlet burner, the purpose of the invention is to provide a kind of simple in construction

Air flue, upper air feeding in center road, upper arc mix air flue, be correspondingly provided with room under burner at least together under main fiery air intake duct, lower center
Air flue, arc lower mix air flue, and main fiery air intake duct forms main fiery admission line, upper and lower air feeding in center road organization center air inlet pipe up and down
Road, lower arcuate mix air flue composition arc gas mixing pipe road, and one end of arc gas mixing pipe road is connected with main fiery admission line, the other end
Annular mixing chamber is connected by gas mixing pipe road angle, the outlet of air feeding in center pipeline communicates with central air chamber, main fiery admission line
Inlet end is correspondingly provided with the entrance point of air feeding in center pipeline, the combustion gas entered from inlet end and air are in main fiery admission line
Mixed gas for the first time is carried out, second of mixed gas is carried out in arc gas mixing pipe road and produces rotation, the mixed gas of rotation is in annular
Third time is carried out in mixing chamber and rotates mixed gas.
The further scheme of the invention, it is provided with the inlet end of the main fiery admission line and air feeding in center pipeline
Gas nozzle, the air door of adjustable air size is correspondingly installed on gas nozzle by air door spring and jump ring.
The further scheme of the invention, described main fiery admission line and air feeding in center pipeline use Venturi tube knot
Structure.
The further scheme of the invention, room is Split type structure under described burner upper chamber and burner, by copper or aluminium or
Zinc alloy diecasting processing and forming forms, or is formed by iron plate punch process.
The further scheme of the invention, room is conjoined structure under described burner upper chamber and burner, by cast iron or copper
Or aluminium or kirsite founding are process.
The further scheme of the invention, described annular mixing chamber set two circles, and form fire, inner ring based on outer ring
For secondary fire, the tricyclic structure that central air chamber is small fire.
After said structure, have the following advantages compared with prior art and effect：One be due to main fiery admission line and
The venturi tube structure of air feeding in center pipeline is directly designed in burner main body, ensures primary air with combustion gas in main fiery air inlet pipe
It is sufficiently mixed for the first time in road and air feeding in center pipeline.Second, the arc being connected with main fiery admission line is set in burner main body
Gas mixing pipe road, combustion gas and air carry out producing rotation, the gaseous mixture of rotation while second of mixed gas in arc gas mixing pipe road
Body carries out third time in annular mixing chamber and rotates mixed gas, not only ensure that mixed gas is uniformly distributed nothing in annular mixing chamber
Pressure difference, make surrounding firepower homogenous combustion, the firepower small situation in big another side, and extend mixed gas on the whole on one side will not occur
Duct length, the mixed gas of rotation is set to mix also more uniformly, burning is more complete.Third, the results show, uses this stove
For the inlaid gas range combustion thermal efficiency of head up to more than 70%, discharge flue gas can control can in below 100ppm, thermic load
More than 4.5KW is designed, the country-level Energy Efficiency Standard of thermal efficiency ratio 63% improves nearly 10%, and discharge flue gas is lower than national standard 500ppm
A lot, thermic load is more much higher than national standard 3.8kw, and each side index can be greatly improved.
