Abstract
The invention relates to a large flame path cover, specifically relates to a large backfire flame cover of a backfire oxygen-enriched energy-gathered gas cooker and belongs to the technical field of the gas cookers. The large backfire flame cover comprises a large flame cover body, wherein a plurality of large flame path combustion-supporting gas channels are formed in the large flame cover body; a large flame path ring is arranged in the large flame cover body; a plurality of large flame path combustion-supporting gas outlets are formed in the large flame path ring; each large flame path combustion-supporting gas outlet is correspondingly communicated with one large flame path combustion-supporting gas channel. A plurality of bracket support chambers are arranged on the upper surface of the large flame cover body. The large backfire flame cover can be applied to combustion-supporting for the principal-combustion flame of the backfire oxygen-enriched energy-gathered gas cooker; a large flame path combustion-supporting gas channel high in air content is used for supporting the combustion of the flame of a large flame path principal-combustion gas channel high in gas content, and therefore, the temperature of the flame is relatively high, the combustion is stable, the thermal efficiency of combustion is high and less exhaust gas is generated.
Description
Technical field
The present invention relates to a kind of large quirk fire cover, back-fire oxygen enrichment cumulative gas-cooker back-fire big fire cover, 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 a kind of back-fire oxygen enrichment cumulative gas-cooker back-fire big fire cover is provided, can be used in the combustion-supporting of the large 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, back-fire oxygen enrichment cumulative gas-cooker back-fire big fire cover comprises big fire road lid, it is characterized in that: in big fire road lid, be provided with the combustion-supporting blast tube of multiple large quirks, large quirk pyrosphere is provided with in big fire road lid, large quirk pyrosphere is provided with the combustion-supporting gas outlet hole of multiple large quirk, and each large quirk combustion-supporting gas outlet hole is corresponding with combustion-supporting blast tube of large quirk to be communicated with.Described big fire road lid upper surface is provided with multiple support bracket support chamber.
Further, the combustion-supporting blast tube of multiple large quirks is uniformly distributed along big fire road lid circumferencial direction.
Further, multiple large quirks combustion-supporting gas outlet hole is uniformly distributed along large quirk pyrosphere circumferencial direction.
Further, the combustion-supporting gas outlet hole of multiple large quirk is inclined hole.
Further, multiple support bracket support chamber is uniformly distributed along big fire road lid circumferencial direction.
Further, big fire road lid upper surface is provided with the limiting bracket identical with support bracket support chamber quantity, and limiting bracket is positioned at support bracket support chamber inner ring.
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 large quirk main combustion flame of back-fire oxygen enrichment cumulative gas-cooker, the large quirk main combustion gas road burned flame that the combustion-supporting gas circuit of large 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.
