Description
Technical field
The present invention relates to a kind of little quirk fire cover, the little fire cover of back-fire oxygen enrichment cumulative gas-cooker back-fire, belongs to gas-cooker technical field specifically.
Background technology
Gas-cooker is applied very extensive socially, and every household all will use gas-cooker.But in use there is big and small a lot of problem in gas-cooker of the prior art.
Existing gas-cooker, adopts combustion gas injection and air to be mixed into fuel gas.Flame temperature during burning is in proper range, and in the fuel gas be 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, and the thermal efficiency is just low, and the combustion gas of consumption is just many.Gas-cooker divides large and small fire second gear, blender mostly is two mixing tubes, the mixing mouth of pipe is provided with air door, is limited the mixed proportion of air and combustion gas by air door, strengthens the mixed proportion that air door can improve air, when increasing oxygen content and improve wind speed, mixer chamber internal gas pressure can be made to raise flow velocity quickening, during burning, flame burns from inside to outside, there will be misfire, the fire that wafts, runout, flame-out phenomenon, impact normally uses, cause unsafe factor, waste energy.
Existing gas-cooker, combustible gas stream sprays along the hole of the fire cover circumferential edge on burner, straight line burning from inside to outside, especially the fiery decentre of big fire cover periphery has certain distance, and flame is not to the heating of pot center, and the high-temperature region of flame flows to the outer of pot, cause pot central temperature low, pot outer temperature is high, even fails Thorough combustion to run off outside pot the sixth of the twelve Earthly Branches, flow velocity is faster, run off more, weak effect, the wasting of resources, scorching hot during use, contaminated environment.
Existing gas-cooker, generally all only uses upper surface and the upper side of flame, and the lower surface of flame and the heat energy of lower side waste in combustion.When particularly pan presses close to flame, flame top cannot produce combustion-supporting flame, and the combustion-supporting flame of both sides can only be leaned on combustion-supporting, so the flame being close to pan can not get combustion-supporting fully.The pan that flame leans on too closely then causes the black mark in the bottom of a pan, burns insufficient, and because distance causes heat-energy losses in then flame combustion process too far away too far away, trace it to its cause and be to lack oxygenating in flame, combustion-supporting insufficient, combustion heat value is not high.The fire cover of conventional gas apparatus generally all only has single channel many grades to go out gas firing, and single channel burned flame of giving vent to anger is stable not, and temperature is not high enough, and the thermal efficiency of burning is lower.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of back-fire oxygen enrichment cumulative gas-cooker back-fire little fire cover, can be used in the combustion-supporting of the little quirk main combustion flame of back-fire oxygen enrichment cumulative gas-cooker, burned flame temperature is higher, flameholding, the thermal efficiency of burning is high, and waste gas is few.
According to technical scheme provided by the invention, the little fire cover of back-fire oxygen enrichment cumulative gas-cooker back-fire comprises little quirk lid, it is characterized in that: in little quirk lid, be provided with the combustion-supporting gas outlet passage of multiple little quirk, be provided with multiple large quirks main combustion gas outlet passage in little quirk lid, multiple little quirks combustion-supporting gas outlet passage is positioned at multiple large quirks main combustion gas outlet passage inner ring; Be provided with little quirk pyrosphere in little quirk lid, little quirk pyrosphere is positioned at little quirk combustion-supporting gas outlet passage inner ring; Little quirk pyrosphere is provided with the combustion-supporting gas outlet hole of multiple little quirk, and each little quirk combustion-supporting gas outlet hole is corresponding with little quirk combustion-supporting gas outlet passage to be communicated with; Little quirk lid top is provided with multiple large quirk column of flame, is provided with a large quirk main combustion gas outlet hole in each large quirk column of flame, and each large quirk main combustion gas outlet hole is corresponding with large quirk main combustion gas outlet passage to be communicated with.
Further, multiple little quirks combustion-supporting gas outlet passage is uniformly distributed along little quirk lid circumferencial direction.
Further, multiple large quirks main combustion gas outlet passage is uniformly distributed along little quirk lid circumferencial direction.
Further, multiple little quirks combustion-supporting gas outlet hole is uniformly distributed along little quirk pyrosphere circumferencial direction.
Further, the combustion-supporting gas outlet hole of multiple little quirk is inclined hole.Multiple large quirk column of flame is uniformly distributed along little quirk lid circumferencial direction.
Compared with the prior art the present invention has the following advantages: structure of the present invention is simple, compact, reasonable, can be used in the combustion-supporting of the little quirk main combustion flame of back-fire oxygen enrichment cumulative gas-cooker, the little quirk main combustion gas road burned flame that the combustion-supporting gas circuit of little quirk that air content is high is high to gas content carries out combustion-supporting, burned flame temperature is higher, flameholding, the thermal efficiency of burning is high, and waste gas is few.
