Description
Technical field
The utility model belong to gas-cooker technical field more particularly to a kind of burner fire lid for gas-cooker and
Using the burner for having the burner fire lid.
Background technology
The burner of existing gas cooker is generally provided with outer ring fire cover and inner-ring fire cover, wherein inner-ring fire cover generally in
Cylinder circumferentially opens up multiple round fire holes, the angle of inclination of these fire holes and horizontal plane in the side wall of cylinder
Angle be generally 20~40 degree.When this burner operation, the apparent oblique outer ejection of interior ring flame is formed when being contacted with the bottom of a pan
Cricoid heating collar, and then cause the bottom of a pan heating uneven.In addition, the inner ring combustion gas of this burner is due to straight without buffering
It connects from the fire hole of inner-ring fire cover and sprays, thus the air velocity at fire hole is very fast, interior ring flame is not easy steady flame.Such as Patent No.
Disclosed in the Chinese utility model patent of ZL201020103772.5 (Authorization Notice No. CN201599854U)《One kind is used for
The inner-ring fire cover of gas-cooker》It is such a inner-ring fire cover, which includes cage in a ring and be arranged in cage
The protective cover at top, circumferentially face equably opens up multiple fire holes to external annulus in cage.In order to improve in order to improve and be input to
The efficiency of combustion for enclosing the combustion gas in fire cover, keeps fuel gas buring more abundant, is provided in many inner-ring fire covers and is separated by with fuel chamber
From central through hole, the required Means of Secondary Air Supplement of fuel gas buring is reached by the circulation of air in central through hole.
But in actual use, since inner-ring fire cover is positioned at the position of the bottom of a pan centre, for common frying pan, inner ring
Fire cover is closest at a distance from the bottom of a pan, causes the useful space above the central through hole of inner-ring fire cover very narrow, reduces by two
The effect of secondary air supply, sometimes, the bottom of a pan excessively almost can block the center and run through close to the central through hole of inner-ring fire cover
Hole makes central through hole not have any effect.On the other hand, during actual use, often there is dirt to be dripped along the bottom of a pan
It is directly fallen to inside gas-cooker on inner-ring fire cover, or by the center through hole, pollutes gas-cooker internal structure, and
It is very unlikely to clean.
In addition, there are the following problems for the structure of ring fire cover and external ring fire cover separate design in existing cooker burner：1、
Inner-ring fire and outer ring fire need to separately design the steady flame structure of the steady flame structure of inner-ring fire cover and outer ring fire cover after separately designing, from
And keeping the structure of entire burner relatively complicated, cost increases, and steady flame effect is undesirable, and stable flame hole is easily stifled, once surely
Flame hole is blocked, and is easily caused de- fire, is misfired, thermocouple difficulty maintains and flame-out phenomenon.2, due to asking there are Internal and external cycle fire
Topic needs to design secondary air inlet to supplement inner-ring fire, burner at present on the market is main to make inner-ring fire fully burn
Secondary air is solved the problems, such as using being supplemented from chassis and supplementing two ways from panel, for supplementing auxiliary air from chassis
Burner for, cause secondary air inlet cleaning be more not easy.
