Description
Technical field
The present invention relates to the oxygen-enriched cumulative gas-cooker back-fire big fire cover of a kind of big quirk fire cover, specifically back-fire, belongs to
Gas-cooker technical field.
Background technology
Gas-cooker is socially applied quite varied, and every household will use gas-cooker.But combustion of the prior art
There is big and small a lot of problems in use in gas kitchen.
Existing gas-cooker, is mixed into fuel gas using combustion gas injection and air.Flame temperature during burning is appropriate
In the range of, in the fuel gas being mixed into, oxygen content is high, and flame temperature is just high, and the thermal efficiency is just high；Oxygen content is low, and flame temperature is just
Low, the thermal efficiency is just low, and the combustion gas of consumption is just many.Gas-cooker divides two grades of large and small fire, and blender mostly is two mixing tubes, mixes the mouth of pipe
Air door is provided with, the mixed proportion of air and combustion gas is limited by air door, increase the mixed proportion that air door can improve air, increasing
When oxygen content and raising wind speed, mixer chamber internal gas pressure can be made to rise high flow rate quickening, flame burns from inside to outside during burning, can go out
Now misfire, the fire that floats, runout, phenomenon of stopping working, impact is normal to be used, and causes unsafe factor, wastes the energy.
Existing gas-cooker, combustible gas stream are sprayed along the hole of the fire cover circumferential edge on burner, from inside to outside straight line
Burning, especially there is a certain distance at the Huo Li center of big fire cover periphery, and flame is not heated to pot center, the high-temperature region of flame
The outer of pot is flowed to, causes pot central temperature low, pot outer temperature is high, or even fail outside fully burning the sixth of the twelve Earthly Branches loss pot, flow velocity is got over
Hurry up, loss is more, and effect is poor, the wasting of resources, scorching hot during use, pollute environment.
Existing gas-cooker, typically all only uses upper surface and the upper side of flame, the lower surface of flame and lower side
The heat energy in face is wasted in combustion.When particularly pan presses close to flame, flame top cannot produce combustion-supporting flame, only
Can be combustion-supporting by the combustion-supporting flame of both sides, so the flame for being close to pan cannot be sufficiently combustion-supporting.The pan that flame is leaned on is too closely then
The black mark in the bottom of a pan is caused, is burnt insufficient, because distance causes heat-energy losses during too remote too remote then flame combustion, trace it to its cause
In oxygenating in flame is lacked, combustion-supporting insufficient, combustion heat value is not high.
The fire cover of conventional gas apparatus typically all only has single channel multi gear to give vent to anger burning, and single channel burned flame of giving vent to anger is not steady enough
Fixed, temperature is not high enough, and the thermal efficiency of burning is relatively low.
Content of the invention
It is an object of the invention to overcome above-mentioned weak point, big so as to provide a kind of oxygen-enriched cumulative gas-cooker back-fire of back-fire
Fire cover, can be used in the oxygen-enriched cumulative gas-cooker of back-fire big quirk main combustion flame combustion-supporting, burned flame temperature is higher, burning
Stable, the thermal efficiency of burning is high, and waste gas is few.
According to the technical scheme that the present invention is provided, the oxygen-enriched cumulative gas-cooker back-fire big fire cover of back-fire includes big fire road lid,
It is characterized in that：The combustion-supporting blast tube of multiple big quirks is provided with big fire drive cap body, is provided with big quirk pyrosphere, greatly in big fire drive cap body
Quirk pyrosphere is provided with the combustion-supporting gas outlet hole of multiple big quirks, and the combustion-supporting gas outlet hole of each big quirk is helped with a big quirk
Combustion blast tube corresponds to connection.The big fire road lid upper surface is provided with multiple support bracket support chambeies.
Further, the combustion-supporting blast tube of multiple big quirks is uniformly distributed along big fire road lid circumferencial direction.
Further, the combustion-supporting gas outlet hole of multiple big quirks is uniformly distributed along big quirk pyrosphere circumferencial direction.
Further, the combustion-supporting gas outlet hole of multiple big quirks is inclined hole.
Further, multiple support bracket support chambeies are uniformly distributed along big fire road lid circumferencial direction.
Further, lid upper surface in big fire road is provided with and support bracket support chamber quantity identical limiting bracket, limiting bracket
Positioned at support bracket support chamber inner ring.
Compared with the prior art the present invention has advantages below：
Present configuration is simple, compact, reasonable, can be used in the main combustion flame of big quirk of back-fire oxygen-enriched cumulative gas-cooker
Combustion-supporting, the main combustion gas road burned flame of the combustion-supporting gas circuit of the high big quirk of the air content big quirk high to gas content is helped
Combustion, burned flame temperature are higher, flameholding, and the thermal efficiency of burning is high, and waste gas is few.

Specific embodiment
The embodiment combined in accompanying drawing is further described by the present invention below：
As shown in Fig. 1 ~ 3, the invention mainly comprises big fire road lid 1, is provided with multiple big quirks in big fire road lid 1 combustion-supporting
Blast tube 4, the combustion-supporting blast tube 4 of multiple big quirks are uniformly distributed along 1 circumferencial direction of big fire road lid.
Big quirk pyrosphere 6 is provided with big fire road lid 1, big quirk pyrosphere 6 is provided with the combustion-supporting gas outlet of multiple big quirks
Hole 5, the combustion-supporting gas outlet hole 5 of multiple big quirks are uniformly distributed along big 6 circumferencial direction of quirk pyrosphere.The combustion-supporting combustion gas of each big quirk
The connection corresponding with the combustion-supporting blast tube 4 of big quirk of venthole 5.
The combustion-supporting gas outlet hole 5 of the plurality of big quirk is inclined hole, and the combustion-supporting combustion gas of big quirk enters inner ring along inclined hole
Combustion flame main to big quirk carries out combustion-supporting, and burned flame temperature is higher, flameholding, and the thermal efficiency of burning is high, and waste gas is few.
Lid 1 upper surface in the big fire road is provided with multiple support bracket support chambeies 2, is installed for supporting to live in support bracket support chamber 2
