Description

General gaseous fuel energy-saving netted range burner with adjustable fire lid

The utility model has related to the burner of gas kitchen ranges, and specifically a kind of burning needs for the combustion gas of adaptation variety classes make the netted fuel gas energy-saving kitchen range of the adjustable generalization fire lid formula of burning area.

Existing gas kitchen ranges had three to improve greatly in recent years, and one is adorned development by cast iron plate outside luxurious stainless steel kitchen range; Its two, igniting electronization is also synchronous with the switch air valve; Its three, secondary wind oxygenating hole, gas burner center obviously increases, and has improved the combustion position in inner ring Fu Huo district.But still exist some problems, especially this crucial main part of gas burner, prolong in decades with sunflower-shaped slotted eye or the garden cellular type lid that catches fire always, igniting is slow, be afraid of wind, tempering, take off shortcomings such as flame, cutoff and sooting pot, be difficult to thoroughly break away from always, more seriously affect the injection of a wind and making full use of of secondary wind.Therefore, the CO content in the flue gas is difficult to drop to minimum point, and the thermal efficiency also is difficult to lift, and this is to abundant burning utilization and the saving of combustion gas, and environmental contamination reduction is all had any problem.Though occurred many netted or ceramic orderliness's shape infrared radiation burners in recent years, its wire side is the plane and lays, secondary wind deficiency; Especially infrared ray is transplanted on the kitchen range open the application from airtight industrially drying chamber, and people's eyes have been increased radiation hazradial bundle.Particularly develop rapidly under the universal situation at present liquefied petroleum gas coke-stove gas, natural gas, the exchange versatility of kitchen range is relatively poor, when the combustion gas kind is changed, because of nozzle and original fire hole area incompatibility, must be when changing nozzle, kitchen range also must be abandoned old purchasing newly, but also have nozzle has been changed, and kitchen range fire hole area still, the former causes a kind of wealth waste because of abandoning old kitchen range to society, bring economic loss to the people, the latter then can not adapt with the combustibility of combustion gas, and fully completing combustion causes energy waste and pollution.

The purpose of this utility model is to release a kind of versatility that is applicable to that existing various gas kitchen ranges is equipped, strengthens all kinds of combustion gas, adopt and uprightly establish net and guard fire hole, the adjustable energy-saving cooking stove head of burning area, so that thoroughly thoroughly do away be afraid of wind, tempering, take off flame, disadvantages such as cutoff, the smoked pot of black smoke, thereby can increase the injection power of a wind and make full use of secondary wind, make its burning more complete, for the raising thermal efficiency, reduction CO, energy savings have been created condition, and have been avoided the radiation injury of infrared ray cooker to human eye.

Task of the present utility model is that the fuel chamber's centre bottom with used pipe type kitchen range hollows out, but the fire cover of turn about in the of equipped, its lower end and kitchen range fuel chamber bottom links by spiral shell and connects, but makes whole fire cover left rotation and right rotation, move up and down, to regulate fire open opening and burning area; With above the kitchen range fuel chamber periphery, along respectively driving symmetrically a circle deep trouth its garden week, the upright metal burning net circle of plug-in mounting ring-type in the groove stitches shape opening, the outer fire of wheel shape, i.e. main flame range to form below the periphery at fire cover top; The garden, inclined-plane of side secondary air central passage oxygenating macropore week boss is laid the big garden of circle fire hole, pack on each fire hole tubular or sheet shape metal net mask, fire in forming, payable at sight flame range in the fire cover top; The master pays the seam of igniting between the flame range, in order to the rapid transmission of inside and outside fire is lighted; Fire cover is stretched out the lower end offside of fuel chamber bottom and is opened a unthreaded hole or screw along center line, and one to two rotary handle is installed.

The utility model makes combustion gas laterally spray burning because main flame range has adopted vertical type metal burning net circle and the outer fire of seam shape opening, contacts with Secondary Air well, and fire hole obstruction accident is also few; Pay the corresponding employing Secondary Air of flame range central passage oxygenating macropore and guard fire hole, strengthened the combustion aid function of interior flame range Secondary Air; Total burning area of netted burning pyrosphere and guard fire hole can increase by 3 to 5 times than old-fashioned kitchen range burning area, and when normal the use, flame is bright blue look; When a wind was excessive, flame became purple or is flameless combustion and produces infrared radiation; Flame envelope is clearly demarcated in the blue fire, burning fully, temperature is high, be fast, the CO of cooking a meal is significantly less than the standard laid down by the ministries or commissions of the Central Government, not smoked pot, the difficult problems such as the igniting of garden shape or bar shaped fire hole gas burner is slow, fearness wind, leaping flame, tempering, cutoff, smoked pot have thoroughly been solved, for further reducing the CO content in the flue gas and improving the thermal efficiency, new approach and mode have been developed; Because fire cover can move up and down, and when gas component changes, just the fire open burning area can be regulated and its adaptation; When changing the combustion gas kind, will not abandon old purchasing newly by kitchen range, only change a nozzle and can reach the general purpose of whole table cooker tool; The utility model fire cover General gaseous fuel energy-saving netted range burner with adjustable can use with general gas kitchen range or baking oven stove are equipped, have sufficient combustion, fully, calorific value is high, fuel consumption is few, the solar term rate can reach more than 20%, pollutes the advantages such as little.If make into upright net tilting or garden hole pattern when hood-shaped in the main flame range in the fire cover outside, fire cover can be fixed or the fire hole area regulated the regulatory function that becomes with the pot distance.Non-net ring also can be turned fire open down and use.

The specific embodiment of the universal netted energy-saving cooking stove head of the utility model fire adjustable combustion gas of lid is provided by the following drawings.What present embodiment provided is the kitchen range that vertical type net circle adds guard garden fire hole structure.
