Description
Technical field
The present invention relates to a kind of gas-cooker, a kind of back-fire oxygen enrichment cumulative gas-cooker, 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 is along the hole ejection of the fire cover circumferential edge on two grades of Fourth Ring back-fire burning sub-assemblies, and straight line burns 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 combustion gas parts of existing gas-cooker are assemblied on kitchen range top support, maintain static, and without closed, unobstructed, be not incubated, easily suffer the impact of air-flow wind, cause heat energy to run off in a large number, flame instability, easily stopped working by wind.
Existing gas-cooker adopts embedded, is arranged on the top of cabinet, and the combustion gas of blender, air inlet port are under stove, and air source is in cabinet.When cupboard door is closed, blocks air flows into, impact burning.Cabinet sealing quality directly affects gas-air mixed proportion, and seal better AIR Proportional lower, fiery temperature is also low, and the thermal efficiency is low.Sometimes cupboard door is needed out to use, unreasonable, inapplicable.During burning, switch cupboard door can make cabinet inner air pressure raise suddenly, and the AIR Proportional in gaseous mixture increases, flow velocity is accelerated, forced fray-out of flame; When opening cupboard door, play contrary problem, to make in cabinet air produce negative pressure, force gaseous mixture to flow backwards, fray-out of flame instantaneously, unburned gaseous mixture is stretched, and dangerously easily has an accident.Some gas-cooker Bian upper air inlet, through because there being hole to stitch bottom gas stove housing, still can not solve above-mentioned deficiency.
