Abstract
The present invention discloses a non-backfire combustion device of a gas range, which comprises a gas control valve, a gas nozzle, a gas and air mixing pipe, a gas and air mixing cavity, a combustor (5) and a fire cover (6), wherein the outer end of the gas and air mixing pipe is provided with a wind adjusting pipe 7 which can move along an axial direction. The gas and air mixing pipe at least has one curved part. Because the combustion device of the gas range of the present invention is improved on five links from a gas inlet, the combustion device does not have a tempering phenomenon during a combustion course so as to ensure the stable combustion and the safe use of the gas range.
Description
The present invention relates to the improvement of kitchen gas stove structure, is a kind of improvement of kitchen gas stove burner structure specifically.
Gas-cooker is to be the kitchen range of fuel with oil liquefied gas, coal gas or natural gas.At present, people are the burner of employed kitchen gas stove in daily life, comprises gas control valve, gas nozzle, mixing tube, burner and Huo Gai.After opening gas control valve, combustion gas enters the gas-air mixing tube through gas nozzle, burns in the outside of burner and the fiery junction of covering.Be provided with air regulating board in the burner end, be used to regulate intake one time, thereby make burning obtain suitable air supply.The problem that this gas-cooker burner exists is the tempering phenomenon that can not prevent fully in the combustion process, in case tempering occurs, the gas-air mixing tube is heated, and not only influences combustion efficiency, and is the hidden danger that stays safe in utilization.Not seeing the non-backfire burner of gas stove identical with structure of the present invention before the present invention finishes as yet uses in daily life, not seeing the non-backfire burner of gas stove identical with structure of the present invention has sale on market, it is on the books in the literature also not see the non-backfire burner of gas stove identical with structure of the present invention.
The object of the present invention is to provide a kind of non-backfire burner of gas stove, tempering phenomenon does not appear in this burner in combustion process, thereby has guaranteed the stable of burning and the safety that gas-cooker uses.
For achieving the above object, the present invention adopts following technical proposals:
Non-backfire burner of gas stove comprises gas control valve, gas nozzle, gas-air mixing tube, gas-air hybrid chamber, burner and Huo Gai, and gas-air mixing tube outer end is arranged with axially displaceable accent airduct, it is characterized in that:
The gas-air mixing tube has a sweep at least;
Said sweep can be the knuckle bending, also can be the circular arc type bending;
The angle of said knuckle bending can for 45 the degree to 180 the degree;
The ratio of the length of gas-air mixing tube and diameter can be between 15 to 1 and 25 to 1;
Between gas-air mixing tube and burner, set up one-level gas-air hybrid chamber again, one-level burner air hybrid chamber is positioned on the burner base, secondary burner air hybrid chamber is positioned at burner inside, combustion gas and Air mixing process are carried out step by step, increased the uniformity of mixing and the stability of burning;
Offer some burner ports at fire lid side, burner port is positioned at the junction of fire lid and burner in the replacement prior art;
Two cover gas control valve, gas nozzle and gas-air mixing tubes are set, link to each other with the fire burns hole, center of burner and the outer shroud fire burns hole of burner respectively.
Be the connection that closely cooperates between said accent airduct and the gas-air mixing tube in the technique scheme, the set screw of transferring airduct is housed in the outer end of gas-air mixing tube.
In the technique scheme, it is between 15 to 1 and 25 to 1 that the gas-air mixing tube has the length of setting up of a sweep and gas-air mixing tube and the ratio of diameter at least, make the flowing velocity and the distance of mist of gas-air that change take place, the possibility that this change makes tempering produce reduces; Between gas-air mixing tube and burner, set up one-level gas-air hybrid chamber again, combustion gas and air are fully mixed in second gas burning air hybrid chamber; The setting of two-stage burner air hybrid chamber has increased the uniformity of mixing, thereby realizes the stability of burning; Offer burner port at fire lid side, the distance between burner hybrid chamber and the flame is strengthened, increased the stability of burning, avoid producing tempering; Two cover gas control valve, gas nozzle and gas-air mixing tubes are set, link to each other with the fire burns hole, center of burner and the outer shroud fire burns hole of burner respectively, can realize the control respectively and the adjusting of centering internal heat and outer ring fire, realize fully burning, prevent tempering.
Effect of the present invention and good effect:
Because the present invention is from fuel gas inlet, burner to gas-cooker on five links improves, use if above-mentioned five technical measures are separately positioned on the gas-cooker, tempering phenomenon does not appear in burner in combustion process, thereby the stable of burning and the safety that gas-cooker uses have been guaranteed, if above-mentioned five technical measures are used on a gas-cooker simultaneously, anti-backfire effect can be better.
Below in conjunction with drawings and Examples structure of the present invention is described in further detail:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the burner structure schematic diagram of the embodiment of the invention;
Fig. 3 is the fire lid structural representation of the embodiment of the invention.
