Description
Technical field
The present invention relates to a kind of fixing device for installing of the burner nozzle on gas-cooker.
Background technology
General all using atmospheric burner on household cooker, it is dimerous with injector by head, and is drawn
The strong and weak pass of being put for atmospheric burner combustion conditions of emitter ejector capacity is important, influences injector ejector capacity each side
In the reason of face in nozzle and injector air-breathing collapsible tube, mixing tube, the concentricity of diffuser pipe and nozzle to throat apart from right and wrong
It is often significant, it by influence primary air introducing number, fired at work so as to influence the stability of burning and kitchen range
The height of burning situation, carbon monoxide content and the thermal efficiency.All it is to make to be calculated with one heart completely when theoretical calculation is with design
It with design, but can not often meet in practical manufacturing process the requirement of design, generate deviation and cause kitchen range at work
The serious consequences such as combustion conditions are poor, generate yellow flame, and carbon monoxide content is exceeded in flue gas, and combustion thermal efficiency is low.
At present the burner of household cooker be usually used iron casting, aluminium alloy compression casting, aluminium alloy centrifugal casting side
Method manufactures, the air-breathing collapsible tube of injector, mixing tube, diffuser pipe concentricity realized by mold, product
Consistency is easily guaranteed that, and common product all in the design of the oral area of air-breathing collapsible tube there are one fixed air door, in its center
Position processes internal thread and loads onto the nozzle of machined good outside nut and forms.The deviation of concentricity mainly has internal thread processing
Caused by the process, cast body is to process using external form as positioning when processing internal thread.And external form can not ensure casting
It is consistent in the process with the shape of inner cavity.And although die casting can guarantee that external form is consistent with inner cavity, but die casting is interior
Chamber and outer wall are all there are draw taper, if air door will re-work installation, it is difficult to ensure that concentricity, is easy to cause a deviation；
During assembling nozzle, the elastic of screw thread will directly affect concentricity and distance；And nozzle directly installs burner with screw thread
On fixed air door, the heat that burner generates at work will be transmitted on nozzle, and nozzle is straight when causing spray nozzle thermal state
Diameter becomes smaller, and stretching heat flow with gas-cooker usage time edge gradually decreases, this does not meet the requirement used.

The positioning pressuring plate（6）And the workpiece formed by plate stamping, wherein there is placement appendix（5）Forming tank
（16）With the hole of positioning appendix position（24）, the cross section of forming tank is V-type（20）Or V-type is connected with circular arc（19）Or circle
Arc（16）One of them；Positioning pressuring plate can also be formed without placing appendix（5）Forming tank（21）Only position appendix
（5）The hole of position（24）；There is fastener hole thereon（25）, the screw hole on position and nozzle fixed frame（13）It is corresponding.
Compared with prior art, the advantage of the invention is that：One kind of the present invention has heat-insulated with positioning exact nozzle
Fixture structure is simple, part is formed with plate stamping, and easily fabricated and assembling reduces manufacture cost；Plate stamping
The part consistency formed is easily guaranteed that nozzle fixed frame protrudes positioning directly in the burner external form formed with aluminium die casting
Column is installed as positioning, preformed hole as screw locking, the air-breathing collapsible tube, mixing tube, diffuser pipe in nozzle and injector
Concentricity, size distance are effectively ensured, simultaneously because nozzle is mounted on nozzle fixed frame, far from this heat of burner
Source, relative to the thermal conductivity factor 237 of aluminium（W/Mk）The thermal conductivity factor 80 of iron（W/Mk）It is 3 times low, play heat-insulated practical effect
Fruit substantially increases the stability of gas-cooker combustion conditions, so as to improve the thermal efficiency of gas-cooker.

Implementation describes
Refering to Fig. 1 and Fig. 2, revealed one of one embodiment of the present of invention has heat-insulated with positioning exact nozzle fixation dress
The injector (1) that burner is formed including aluminium die casting is put, is connected to and with the protrusion positioning column in aluminium diecasting external form（3）As
Positioning;Die casting preformed hole is as screw（2）Lock nozzle fixed frame（4）, in nozzle fixed frame（4）Slot in installation it is defeated
Tracheae（5）, positioning pressuring plate is pressed against on appendix（6）, use screw（7）With nozzle fixed frame（4）Be locked appendix（5）.It is defeated
Tracheae（5）End have internal thread（17）Nozzle is fixedly mounted（8）, shunk in the air-breathing of aluminium die casting into injector（9）'s
End is equipped with fixed air door（22）And using air door center as the rotary damper in axle center（23）.Implement from Fig. 1
The sectional view of example can be seen that nozzle and air-breathing collapsible tube in Venturi tube（9）, mixing tube（10）, diffuser pipe（11）Height with one heart and
Nozzle（8）To throat（26）Distance by positioning the hole (14) and appendix (5) of appendix (5) position on nozzle fixed frame (4)
There are one the flanges in the vertical center of circle for outer wall system apart from end certain distance（18）It matches so that dimensional accuracy is reliably protected
Card.It can be seen that nozzle fixed frame (4) is molded by plate stamping from the stereogram of Fig. 3 nozzles fixed frame (4), periphery drawing
Molding, another part have enough rigidity and intensity, two location holes thereon（3）4, space degree of freedom can be eliminated installing, two
A screw hole can eliminate 2, space degree of freedom, and positioning is reliable；Its moulding is to meet nozzle (8) to receive with the air-breathing in injector
The draw（9）, mixing tube（10）, diffuser pipe（11）It is concentric, with throat（26）Distance it is definite and reliable with burner injector
Connection can have many modifications；It can be seen that from Fig. 1 and Fig. 2 and two nozzles be installed on nozzle fixed frame (4)（8）It is defeated with two
Tracheae（5）With two injectors（1）It is connected, positioning pressuring plate（6）Fixation and locking can be reliably fixed with a screw；
Spirit disclosed according to one embodiment of present invention is installed with one on the nozzle fixed frame that equally can be subject to modification with one
A nozzle（8）With an appendix（5）With an injector（1）It is connected, the both sides for being subject to the positioning pressuring plate bracket groove of modification are used
Two screws are fixed locking, can also be on one side with using a screw locking while sticking up linkage.As can be seen from Figure 5 it sprays
Mouth fixed frame（4）Slot（12）There can be many mutation.As can be seen from Figure 8 positioning pressuring plate（6）Slot（16）Can also have
Many mutation.
Although depicting the present invention by embodiment, it will be appreciated by the skilled addressee that there are many deform by the present invention
With variation without departing from the spirit of the present invention, it is desirable to which appended claim includes these deformations and deforms without departing from the present invention
Spirit.
