Specific embodiment

The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model Description, but this utility model is not limited to these embodiments.

As shown in Figures 1 to 4, the burner of this improvement includes：

Outer burner 11, in circular setting, fastening on outer burner 11 has outer fire cover 12 and outer fire cover 12 and outer burner 11 Surround to form outer hybrid chamber 111,11 bottom of outer burner is provided with the multiple main channels 31 with 111 UNICOM of outer hybrid chamber, it is main logical The cross section in road 31 is square setting；

Interior burner 21, wears in the middle part of outer burner 11, on interior burner 21 fasten have inner fire cover 22 and inner fire cover 22 with it is interior Burner 21 surrounds to form inner mixing chamber 211, and 21 bottom of interior burner is provided with the subchannel 32 with 211 UNICOM of inner mixing chamber；

Conduit assembly, below outer burner 11, is provided with conduit assembly and 32 corresponding air inlet pipe of subchannel 42 and with 31 one-to-one multiple main air inlet pipes 41 of each main channel；

Point the column of flame 50, be set to it is multiple, each point column of flame 50 with conduit assembly UNICOM, point the column of flame 50 extend straight up And be resisted against in 21 outer peripheral sidewall of interior burner；

Pillar 60, is set to multiple, and each pillar 60 is vertically installed at below conduit assembly.

For this purpose, this utility model devises a kind of burner of improvement, by arranging the main air inlet pipe of multiple mating reactions 41 with main channel 31 so that combustion gas circulation mixing in the burner is abundant, is easy to follow-up burning work.

In the present embodiment, preferred main channel 31 is three with the quantity of main air inlet pipe 41, for supplying in outer burner 11 Combustion gas, interior burner 21 then coordinate delivery of fuel gas by subchannel 32 with secondary air inlet pipe 42.Due to burning when, flame often along Pan extends laterally, is independently supplied 21 combustion gas of interior burner herein and may insure that pan is heated evenly.

During work, a part of combustion gas Jing main air inlet pipes 41 enter corresponding main channel 31, into outer mixed in outer burner 11 Chamber 111 is closed, is finally burnt by the output of outer fire cover 12；Jing air inlet pipe of Some gases 42 enters subchannel 32, into interior stove 21 inner mixing chamber 211, is finally burnt by the output of inner fire cover 22.

Inner fire cover 22 and the output for arranging on the one hand control combustion gas of outer fire cover 12, on the other hand can avoid exterior materials Flow in corresponding burner, affect burner operation.

During burning, the external control point column of flame 50 is lighted a fire, and specifically, is provided with ignition electrode (in figure in a column of flame 50 It is not shown), ignition is carried out by controlling igniting for combustion gas.The point column of flame 50 is resisted against in 21 outer peripheral sidewall of interior burner, just In combustion gas is quickly lighted, the quantity of the preferred point column of flame 50 is two herein.

What burner was often operated in gas-cooker, burner is by being arranged on the pillar 60 of bottom and firing Gas kitchen is fixedly connected, and in the present embodiment, the quantity of pillar 60 is preferably four, is evenly distributed on below conduit assembly, gives and fire Burner supporting role.

Further, each main channel 31 is uniformly distributed around 11 axial line of outer burner, and each main channel 31 bends extension To outer burner 11 and main channel 31 inwall pass through one domatic 311 and outer hybrid chamber 111 bottom surface it is in smoothing junction.

Specifically, three main channels 31 are uniformly distributed in 11 bottom of outer burner.As the cross section of main channel 31 is square Arrange, in order to ensure that combustion gas is that circulation is unobstructed into outer hybrid chamber 111, the inwall of main channel 31 is mixed with outer by one domatic 311 The bottom surface for closing chamber 111 is in smoothing junction, mixes gas circulation abundant.

Preferably, the upper surface of inner fire cover 22 caves inward to form the conical surface 221, offers and mix with interior on inner fire cover 22 The multiple interior fire output hole 222 of 211 UNICOM of chamber, interior fire output hole 222 around 22 axial line of inner fire cover be uniformly distributed and each in go out fire Hole 222 extends vertically through the conical surface 221 and arranges.

The setting of interior fire output hole 222 is easy to control combustion gas uniformly export, and the setting of the conical surface 221 when combustion gas is exported compared with For concentrating, be conducive to ignition, wherein interior fire output hole 222 extends vertically through the conical surface 221 and arranges, and further ensures that combustion gas court Center output, it is ensured that the centrality of flame of centre, combustion efficiency are good.

It is noted that the edge ring in the conical surface 221 has opened up some grooves around interior fire output hole 222 so that the conical surface 221 Petal-like structures, and one petal of the correspondence of fire output hole 222 in each is presented, strengthens overall aesthetic property.

Additionally, run through in the middle part of interior burner 21 that through hole 213 is offered, and through hole 213 is upwardly extended and passes through inner fire cover 22, just Enter in air, with combustion gas mixing fully, be conducive to the abundant burning of combustion gas.

It is further preferred that the upper surface portion outwardly convex of outer fire cover 12 forms multiple semilunes that head and the tail are sequentially connected Projection 121, the upper surface of each semilune projection 121 offer equally distributed multiple first outer fire output holes 122, and each half The lateral surface of month shape projection 121 offers equally distributed multiple second outer fire output holes 123, and each outer fire output hole is mixed with outer 111 UNICOM of chamber.

Combustion gas in outer burner 11 is finally exported via the first outer fire output hole 122, the second outer fire output hole 123, each outgoing fire The setting in hole is equally easy to control combustion gas uniformly to export, and is easy to combustion gas fully to burn.Wherein, the setting of semilune projection 121, carries High overall aesthetic property.

Preferably, in 11 outer peripheral sidewall of outer burner through equally distributed multiple air intake ducts 112 are offered, in interior burner 21 The auxiliary tank 212 with 211 UNICOM of inner mixing chamber is offered in outer peripheral sidewall.

The setting of air intake duct 112 is easy to air to enter, air intake duct 112 not with 111 UNICOM of outer hybrid chamber, air can be via entering Wind groove 112 enters auxiliary tank 212, travels further in inner mixing chamber 211 with combustion gas mixing uniformly, is easy to the abundant combustion of combustion gas Burn.Preferably the quantity of air intake duct 112 is three herein.

The burner structure of this improvement is reasonable in design, using multiple main channels 31 for cooperating and main air inlet pipe 41, makes The gas circulation mixing being passed through in outer burner 11 is abundant, is conducive to the carrying out of subsequent combustion；Subchannel 32 and secondary air inlet pipe 42 Arrange, for supplying the combustion gas in interior burner 21, make combustion gas be evenly distributed；The structure design of inner fire cover 22 and outer fire cover 12 and The setting of semilune projection 121 causes burner moulding more attractive in appearance.

Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment Mode substitute, but without departing from it is of the present utility model spirit or surmount scope defined in appended claims.
