Embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As shown in Fig. 1~5, a kind of burner fire lid of gas-cooker, including circular fire cover body 1, the fire cover body 1
Including annular upper wall 11 and internal ring wall 13 that is vertical respectively by the medial and lateral edge of the annular upper wall 11 or extending obliquely downward
With external annulus 12, and the annular upper wall 11, internal ring wall 13 and external annulus 12 enclose and set to form mixed air cavity 10.On above-mentioned external annulus 12
Axially spaced to be equipped with fire output hole 2, in the shape of a spiral, its one end is and mixed air cavity in the duct 20 of the fire output hole 2 in the present embodiment
The air inlet 22 of 10 connections, the other end is crater 21.In the present embodiment the duct 20 of fire output hole 2 in the shape of a spiral, so in height
In the case of pressure, compared with straight-through duct, outlet speed slows down, so as to effectively avoid from flame；And under low voltage situations, air-flow is not
Easily return in fire output hole, so as to reduce tempering；In addition, under normal barometric pressure, this kind of fire output hole be also less likely to occur tempering and
From flame, so as to ensure the stability of fire output hole burning.
Further, the pitch in the duct 20 of fire output hole 2 is 4~15mm in the present embodiment, the air inlet 22 in the duct 20
Central point O1With the central point O of crater 212Line O1O2Angle α with horizontal plane is 25 °~60 °.The duct of fire output hole 2
20 cross-sectional area is 1.77~7.10mm2.The cross section in the duct 20 of fire output hole 2 can be diversified forms in the present embodiment,
Such as circular, oval, square, triangle, it is preferable that the cross section in the duct 20 of fire output hole 2 is circle, its a diameter of 1.5
~3.0mm.
Further, the duct 20 of fire output hole 2 includes air inlet section 201, changeover portion 202 and goes out fiery section 203, the air inlet section
201 reverse to form above-mentioned changeover portion 202 to upper right, and the changeover portion 202 to left down direction reverse and formed it is above-mentioned go out fire
Section 203, air inlet 22 are located at the free end of air inlet section 201 and rounded, and crater 21 is located at the free end of fiery section 203, and
Outwards pulled along the lateral wall of fire cover body 1 on crater wall left end edge.
Specifically, in the present embodiment, the pitch in the duct 20 of air inlet section 201 is：4~8mm, cross-sectional area are：5.1~
7.1mm2, duct 20 is a diameter of：4~8mm.The setting of 201 concrete structure of air inlet section, so that it is to from 22 access aperture of air inlet
The combustion gas in road 20 and the resistance of air are smaller, then allow combustion gas and air to be rotated along cell walls, so that combustion
Gas and air are more fully mixed, are more uniform.
The pitch in the duct 20 of changeover portion 202 is：8~15mm, cross-sectional area are：1.77~5.1mm2, duct 20 is straight
Footpath is：8~15mm.After the rotation mixing of combustion gas and air by air inlet section 201, second of rotation is carried out in changeover portion 202,
So as to further enhance the rotatory power of combustion gas and air.
The pitch for going out the duct 20 of fiery section 203 is：6~10mm, cross-sectional area are：5.1~7.1mm2, 20 diameter of duct
For：6~10mm.Third time rotation is carried out in fiery section 203 is gone out through second of rotating combustion gas and air, by rotating three times,
Rotation is formed in the flame that crater 21 goes out, its rotatory power is most strong, is combined with the shuffle structure of crater 21, can inhale around volume
More auxiliary airs, so that burning is more abundant, the flue gas for generation of burning is also less, while also can effectively avoid tempering
With the generation from flame phenomenon.
In the shape of a spiral, the mixed gas of combustion gas and air passes through multiple rotary, and mixing is more in the duct of fire output hole in the present invention
Add abundant, uniform, the mixed gas of combustion gas and air forms rotating flame after exporting out from fire hole, and single fire hole can shape
Into independent rotating flame, volume inhales more auxiliary airs, and can be sufficiently mixed with auxiliary air, and incorporation time is opposite to extend,
The flame combustion residence time, also opposite extension, efficiency and flue gas got a promotion, and efficiency of combustion improves.
By test of simulating and draw a design, the present invention is less than 100ppm in conversion flue gas (CO), and efficiency reaches level-one efficiency
More than 63%, no tempering, without from flame, is tested (GB16410-2007) using new national standard.
