Description
The utility model relates to a kind of burner of household gas cooker.
At present, the burner used of gas-cooker nearly all has axially injector of 1 or 2---3.Owing to structural reason, when they were used on cabinet type (or claiming embedded) kitchen range, carbon monoxide content etc. was difficult to satisfy the national standard requirement of this series products in its combustibility and the waste gas.The radially burner of injector of one of a kind of employing is abroad arranged, has partly solved the problems referred to above, but following shortcoming is arranged:
1, owing to have only nozzle to supply with the radially air of injector injection burning usefulness of combustion gas and,
Thereby having limited the specified heat flow (power) of burner, the diet that is difficult to satisfy the Asians is practised
The needs of being used to the cooking of requirement vigorous fire.
2, in the whole adjustable range between specified heat flow and minimum thermal flow, the fire hole of burner
Area is constant, so thermal intensity of fire port (heat flow of unit fire hole area) and combustibility
Change very big.
3, during the different combustion gas of burning, the fire hole area is identical, does not meet fire hole when burning different combustion gas
The requirement that calorific intensity is different.
The purpose of this utility model provides a kind of gas burner with two compound injectors, and its specified heat flow is big, and adjustable range is wide, and thermal intensity of fire port and combustibility change lessly in whole working range, and are fit to the requirement of the different combustion gas of burning.
The purpose of this utility model is achieved in that a kind of gas burner with two compound injectors, it is characterized in that comprising an outer ring channel, ring passage and a cup shell in one, wherein cup shell is in order to fixing nozzle, and other member of supporting outer ring channel and interior ring passage, outer ring channel is by the outer shroud nozzle, the compound injector of outer shroud, form with the outer shroud distributor, the compound injector of outer shroud comprises axial injection part and injection part radially, in the ring passage chew by interior ring spray, the compound injector of interior ring and interior ring distributor are formed, the compound injector of interior ring comprises radially injection part of an axial injection part and.
Aforesaid gas burner with two compound injectors, it is characterized in that axial injection partly is the cross-sectional passage of enclosing along the axis direction of nozzle ejection gas-flow, radially injection partly is to be right after after axial injection part, along the radial distribution of gas-flow ejection axis, the passage that its sectional area enlarges gradually.
The utility model increases the air capacity of injection because adopted two axial injections parts and the compound injector that partly makes up of injection radially.Adopt two-way control combustion gas to burn respectively, specified heat flow is increased.The two-way combustion gas can be simultaneously by separately distributor burning, also can have only one tunnel (interior ring) distributor to burn separately, make thermal intensity of fire port when regulating heat flow, changes lessly, thereby combustibility is stable, adjustable range expansion.At different combustion gas, adopt the distributor of nozzle with different fire hole areas (the single fire hole area and the gross area) in different apertures, in the time of just satisfying various fuel gas buring to the requirement of thermal intensity of fire port.
Below in conjunction with accompanying drawing concrete structure of the present utility model is elaborated.

The utility model comprises an outer ring channel A, a ring channel B and a cup shell 5 (as shown in Figure 1) in one.
Outer ring channel A is by outer shroud nozzle 1, and compound injector 3 of outer shroud and outer shroud distributor 6 are formed (as shown in Figure 4).The compound injector 3 of outer shroud comprises axial injection part 8 and injection part 9 radially.
Interior ring channel B chews 2 by interior ring spray, and compound injector 4 of interior ring and interior ring distributor 7 are formed (as shown in Figure 7).In the compound injector 4 of ring comprise radially injection part 11 of an axial injection part 10 and.
The axial injection of compound injector partly is the cross-sectional passage of enclosing along the axis direction of nozzle ejection gas-flow, the air inlet section that it has a cross section to become to shrink along axis, its smallest cross-sectional place is a throat, be right after the diffuser that can have to become to enlarge thereafter along axis, in the present embodiment, after the throat of injection part 10 diffuser is arranged at inner axle, annulate shaft does not have diffuser after the throat of injection part 8 outside.The radial component of compound injector is right after after the former, and it is along the radial distribution of gas-flow ejection axis, the passage that its sectional area enlarges gradually.Radially the injection part can be one, also can be a plurality of.In the present embodiment, interior ring radially injection partly is one, and external loop diameter partly is 3 to injection.
When opening burnt gas switch, combustion gas sprays into the axial injection part 8 or 10 of corresponding compound injector 3 or 4 at a high speed from nozzle 1 or 2, forms local decompression, and the cavity that attracts air to be formed by cup shell 5 enters axial injection part, and and combustion gas mixing.Gaseous mixture passes through accordingly radially injection part 9 or 11 deceleration superchargings respectively, and combustion gas and air are further mixed, flow through then separately distributor 6 or 7 fire hole burn.The combustion gas that enters nozzle 1 and 2 is controlled by gas valve (illustrating), can spray into or only chew 2 from interior ring spray from two nozzles simultaneously on request to spray into, to regulate the required heat flow of the cooking.In the previous case, heat flow is big (until specified heat flow), and two distributor are worked simultaneously.Then a kind of situation heat flow is less, but the ring distributor is being worked in having only.Therefore in whole working range, thermal intensity of fire port changes less, and total specified heat flow improves and adjustable range expansion.When the combustion gas kind not simultaneously, can change the different nozzle in aperture 1 and 2, and the distributor 6 and 7 of fire hole area difference (the single fire hole area and the gross area), just can satisfy the specified heat flow of the thermal intensity of fire port and the needs of the requirement of this kind fuel gas buring, and make flameholding.
The utility model the heat flow separated into two parts that needs, is supplied with combustion gas and air by different separately nozzles and injector when work.The compound injector that adopts axial injection to combine with injection radially improves the injection effect, and reduces physical dimension.Combustion gas is sent into different distributor with air mixing back by different passages and is burnt.Two parts combustion gas can be adjusted its flow by different control devices, can obtain desired maximum heat flow when supplying with maximum stream flow simultaneously.Reduce to one regularly when regulating gas flow, close the air feed of outer shroud nozzle and only use nozzle, injector and the distributor work of interior ring passage.The heat flow of this moment is less, but corresponding fire hole area is also less, thereby it is less that thermal intensity of fire port is changed, and combustibility is stable.When using different combustion gas, the distributor of nozzle and different fire hole areas (the single fire hole area and the gross area) by changing different apertures, the thermal intensity of fire port requirement in the time of can satisfying this kind fuel gas buring.
