Description
Technical field
The utility model relates to a kind of back-fire oxygen enrichment cumulative gas-cooker back-fire ring assemblies, belongs to gas-cooker technical field.
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 purpose of this utility model is to overcome above-mentioned weak point, thus a kind of back-fire oxygen enrichment cumulative gas-cooker back-fire ring assemblies is provided, the secondary combustion-supporting burned flame temperature that can be used in the main combustion flame of back-fire oxygen enrichment cumulative gas-cooker is higher, flameholding, the thermal efficiency of burning is high, and waste gas is few.
According to the technical scheme that the utility model provides, back-fire oxygen enrichment cumulative gas-cooker back-fire ring assemblies comprises little quirk back-fire ring and large quirk back-fire ring, little quirk back-fire ring is positioned at large quirk back-fire ring inner ring, it is characterized in that: described little quirk back-fire ring is provided with the combustion-supporting gas outlet hole of multiple little quirk, multiple little quirks combustion-supporting gas outlet hole is uniformly distributed along little quirk back-fire ring circumferencial direction; Described large quirk back-fire ring is provided with the combustion-supporting gas outlet hole of multiple large quirk, and multiple large quirks combustion-supporting gas outlet hole is uniformly distributed along large quirk back-fire ring circumferencial direction.
Further, the combustion-supporting gas outlet hole of multiple little quirk is inclined hole.
Further, the combustion-supporting gas outlet hole of multiple large quirk is inclined hole.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, can be used in the secondary combustion-supporting of the main combustion flame of back-fire oxygen enrichment cumulative gas-cooker, the main combustion gas road burned flame that the combustion-supporting gas circuit 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.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1, the utility model mainly comprises little quirk back-fire ring 1 and large quirk back-fire ring 3, and little quirk back-fire ring 1 is positioned at large quirk back-fire ring 3 inner ring.
As shown in Figure 2, described little quirk back-fire ring 1 is provided with the combustion-supporting gas outlet hole 2 of multiple little quirk, multiple little quirks combustion-supporting gas outlet hole 2 is uniformly distributed along little quirk back-fire ring 1 circumferencial direction, little quirk back-fire ring 1 is positioned at back-fire little fire cover lid when installing, and is communicated with the multiple little quirk combustion-supporting gas outlet passage one_to_one corresponding arranged in back-fire little fire cover lid.
The described combustion-supporting gas outlet hole 2 of multiple little quirk is inclined hole, and the combustion-supporting combustion gas of little quirk enters inner ring along inclined hole and carries out secondary combustion-supporting to the main combustion flame of little quirk, and burned flame temperature is higher, flameholding, and the thermal efficiency of burning is high, and waste gas is few.
As shown in Figure 3, described large quirk back-fire ring 3 is provided with the combustion-supporting gas outlet hole 4 of multiple large quirk, multiple large quirks combustion-supporting gas outlet hole 4 is uniformly distributed along large quirk back-fire ring 3 circumferencial direction, large quirk back-fire ring 3 is positioned at back-fire big fire cover lid when installing, and is communicated with the multiple large quirk combustion-supporting gas outlet passage one_to_one corresponding arranged in back-fire big fire cover lid.
The described combustion-supporting gas outlet hole 4 of multiple large quirk is inclined hole, and the combustion-supporting combustion gas of large quirk enters inner ring along inclined hole and carries out secondary combustion-supporting to the main combustion flame of large quirk, and burned flame temperature is higher, flameholding, and the thermal efficiency of burning is high, and waste gas is few.
The utility model structure is simple, compact, reasonable, can be used in the secondary combustion-supporting of the main combustion flame of back-fire oxygen enrichment cumulative gas-cooker, the main combustion gas road burned flame that the combustion-supporting gas circuit 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.
