Description
Technical field
The present invention relates to gas-cooker fields, and in particular to a kind of burner for gas-cooker.
Background technology
Tempering and steady flame are always the Research Emphasis of gas burner；Existing burner is controlled by fire cover fire output hole
Fire hole intensity processed avoids being tempered by the way that stable flame hole is arranged.
For example, disclosed in CN200720176575.4《A kind of cooker burner》, pass through the structure shape of change burning disk
At the steady flame slot of central flame and the steady flame slot of main fire, to avoid central flame and main fire tempering.It controls fire hole by controlling fire output hole
The wall thickness of intensity, fire cover is thicker, and material cost is high, and complicated, needs process component more.
Invention content
The technical problem to be solved by the present invention is to provide one kind for the present situation of the prior art stable flame hole need not be arranged
Fire hole intensity and good, the at low cost burner for gas-cooker of steady flame effect can effectively be controlled.
Technical solution is used by the present invention solves above-mentioned technical problem：This is used for the burner of gas-cooker, including base
Seat and interior ring fire cover and the external ring fire cover being connected on pedestal, the top surface inner wall of the interior ring fire cover form center with annular peripheral wall
Mixing chamber, the annular peripheral wall of the interior ring fire cover offer the inner ring fire hole of the extraneous center mixing chamber of multiple connections；The outer shroud
The top surface inner wall of fire cover forms outer shroud mixing chamber with annular peripheral wall, and the external ring fire cover annular peripheral wall is equipped with multiple main fire holes；
The pedestal is equipped with the center blast tube for being connected to the center mixing chamber and the outer shroud combustion gas for being connected to the outer shroud mixing chamber
Channel；
It is characterized in that：
Vertical annular baffle is additionally provided on the pedestal, the outer shroud mixing chamber is divided into positioned inside by the partition board
Mixed air cavity and cushion chamber positioned at outside；And have between the upper edge of the baffle and the inner surface of the external ring fire cover
It is connected to the gap of the mixed air cavity and cushion chamber；
The outer shroud blast tube is connected to the mixed air cavity.
Preferably, the outer shroud blast tube has multiple, axially through on the pedestal, and along the outer shroud mixing chamber
It is arranged circumferentially.The structure enables the gaseous mixture of combustion gas and primary air even into outer shroud mixing chamber, is conducive to fire
Gas uniformly and stably burns.
As an improvement, can also be also equipped at intervals on the pedestal it is multiple radially penetrate through for inside ring fire hole it is secondary
The air supply passage of tonifying Qi.
It is preferred that the longitudinal section area of the air supply passage is gradually reduced from outside to inside.
Preferably, the air supply passage is taper hole.The air that the structure of the air supply passage is conducive to secondary supplement accelerates stream
Dynamic, tonifying Qi effect is good.
Compared with prior art, in the burner provided by the present invention for gas-cooker can not only there is the design of partition board
Effect control fire hole intensity, and steady flame effect is good, avoids the generation of tempering phenomenon；And it is controlled in the prior art using fire hole
Fire hole intensity, fire cover wall thickness is big, of high cost；And the present invention by partition board be arranged on pedestal, due to pedestal may be used it is at low cost
Material preparation, therefore the manufacturing cost of burner can be substantially reduced.

Specific implementation mode
Below in conjunction with attached drawing embodiment, present invention is further described in detail.
As shown in Figures 1 to 4, which includes：
Pedestal 1 is the support base of fire cover, standby using aluminum；Gas is mixed for connecting ejector pipe (not shown) and fire cover
Room.The middle part of pedestal 1 is equipped with center blast tube 11, is equipped at intervals in the periphery of center blast tube 11 on pedestal 1 multiple outer
Ring blast tube 12；And outer shroud blast tube 12 is arranged with the interval of center blast tube 11, forms tonifying Qi chamber 13 between the two.
Center blast tube 11 is connected to the first ejector pipe (not shown), and outer shroud blast tube 12 is connected to the second ejector pipe
(not shown).
In the present embodiment, each outer shroud blast tube 12 is and outer axially through pedestal 1 and being arranged circumferentially along pedestal
The cross section of ring blast tube 12 is double "u"-shapeds.
Multiple air supply passages 34 being used for 13 secondary air compensating of tonifying Qi chamber radially penetrated through are also equipped at intervals on pedestal 1；
The longitudinal section area of air supply passage 34 is gradually reduced from outside to inside, and the present embodiment is taper hole.
The top surface of pedestal 1 is equipped with vertical annular baffle 4.
External ring fire cover 3, top surface inner wall form outer shroud mixing chamber 32, exterior annular peripheral wall with inside and outside both sides annular peripheral wall
It is equipped with multiple main fire holes 31.Partition board 4 is extend into outer shroud mixing chamber 32, and outer shroud mixing chamber 32 is divided into positioned at the mixed of inside
Air cavity 321 and cushion chamber 322 positioned at outside；Have between the upper edge of partition board 4 and the inner surface of external ring fire cover 3 and is connected to mixed gas
The gap 33 of chamber 321 and cushion chamber 322.The connection of outer shroud blast tube 12 mixes air cavity 321, and main fire hole 31 is connected to cushion chamber 322.
Interior ring fire cover 2, top surface inner wall form center mixing chamber 22 with annular peripheral wall, multiple companies are offered on annular peripheral wall
The inner ring fire hole 21 of logical center mixing chamber 22；Center mixing chamber 22 is connected to center blast tube 11.
When work, combustion gas and primary air gaseous mixture enter each outer shroud blast tube via ejector pipe, subsequently into mixed gas
Chamber enters cushion chamber via the gap between partition board and external ring fire cover, finally sprays burning from each main fire hole.
Gaseous mixture increases via flow velocity when gap, can control fire hole intensity by the size in gap, can effectively be thinned outer
The wall thickness of ring fire cover, and increased partition board is arranged on pedestal 1, pedestal 1 is to be prepared using aluminium, therefore the cost of burner is big
It is big to reduce；Meanwhile gaseous mixture enters cushion chamber via gap, volume increases suddenly, and gas flow rate reduces, main fire hole flare height
Low, steady flame effect is good；The design of partition board avoids the generation of tempering phenomenon simultaneously.
Combustion gas and primary air gaseous mixture enter center blast tube by the first ejector pipe simultaneously, then mix gas via center
Room sprays from inner ring fire hole and burns；In combustion process, outside air enters tonifying Qi chamber, the fire in internal ring fire hole via air supply passage
Flame enters secondary air compensating, ensure that abundant burning.
